The Clamp carrier is the basis for customers to find new designs
The clamp carrier is one of the main equipments for the production of blockboard (large core board). It is mainly used to make small-diameter logs, rotary-cut wood cores, timber sheets and other raw materials. , extrusion, heating and other processes to make the whole surface of the solid core board equipment, the jigsaw machine is mainly composed of hydraulic system, pneumatic system.
The clamp carrier working principle:
Using the Zener breakdown characteristics of the Zener diode, a high-frequency signal with a frequency of several hundred megahertz can be obtained. The circuit is shown in the figure. The signal taken from output V01 is a single frequency signal that can be used to align the resonant frequency in the tuned loop. The signal taken out from the output V02 is a broad-spectrum high-frequency signal, and the tuning between the input resonant circuit and the local oscillator tuning circuit in the superheterodyne radio can be performed. The clamp carrier frequency range of the generator is l00kHz~27MHz, which is divided into five frequency bands: 100kHz~300kHz~lMHz~3MHz~9MHz~27MHz. The output voltage of the signal generator is approximately 9mV. The coils L1 to L5 are wound on a skeleton having a fine-tuning magnetic core, L1 to L3 are made of Φ0.1 mm enameled wires, and L4 and L5 are made of Φ0.2 mm enameled wires. The number of turns of Ll~L5 is 270+270, 260, 80, 30 and 10匝. After assembly, calibrate with a standard signal generator and make a frequency scale on the knob of variable capacitor C3. Adjusting the potentiometer RP makes the output high frequency signal strongest. There is no special requirement for the voltage regulator used in the circuit, except that the power supply voltage should be higher than the regulation voltage to ensure that the Zener diode works at the inflection point of the characteristic curve.
The clamp carrier working process is:
1.Feeding and conveying:
The length of the cast sheet is not less than 100 mm. The width is not less than 1200mm, the thickness is between 1.2mm-3.5mm, and the material to be spliced ??is placed on the conveyor belt for conveying.
2.material board correction:
The conveyor belt conveys the material plate, and first passes the correction device to perform the edge correction. Achieve one side, so the clamp carrier finished board is based on a side, and it will be easy to operate in the plywood production process in the future.
3.Front drive:
The calibrated material plate is transported to the front drive, and the front drive is a bottom-up compression drive, which is to flatten the feed plate.
4.cutting and control:
After the material plate enters the front drive flattening conveying, it is detected by the pressure wheel type micro switch, the cutting distance is calculated by the rotary encoder, and the pulse signal is sent to the PLC (computer), combined with the cut set already set on the display text. The data executes the cut program.
The cutting program cuts one knife before and after, and the purpose is to cut the front and back sides of the material into parallel sides for docking.
5.after the drive:
The rear drive is a transfer device that combines cutting and cutting after cutting and cutting.
The front part of the rear drive is designed to be movable up and down. It needs to be leveled when the material is transferred. clamp carrier is used for material transfer. It does not need to be lifted up automatically when the material is delivered. The purpose is to let the cut waste material fall naturally. It will not enter the rear drive to make a docking puzzle.
6.docking puzzle:
The trimmed material plate is driven by the rear drive, and the glue photoelectric switch controls the applicator claw to lift up, and touches the hot melt glue on the rubber claw on the cross section of the traveling medium plate.
Synchronization of the cross-section of the feed plate section, under the material plate, the wire filled with the hot-melt glue is evenly pressed on the opposite side of the traveling material plate by the fixed pressure roller, and then the copper wheel immersed in the water is rapidly cooled by the pressure of the copper wheel. The glue line is firmly adhered to the material board, so that the cut and sized boards are connected one by one.
7.the finished board cut:
The spliced panels are joined together to form an infinitely long monolithic panel that needs to be cut to the required length for palletizing or use.
After the whole plate passes through the rear cutter, it enters the conveyor belt. Above the conveyor belt, there is a photoelectric switch. When the photoelectric switch detects that the whole plate will start, the cutter is cut off. At this time, clamp carrier the whole plate will be cut off, and the length of the cutting depends on the photoelectric switch. The distance from the cutter to the cutter, the longer the photoelectric switch is cut from the cutter, the longer the length of the photoelectric switch is from the cutter. The shorter the length of the photoelectric switch is, the shorter the length of the plywood is generally about 2500 mm.
8.the finished product board:
The finished board that has been spliced and cut off within the specified size is transported through the conveyor belt into the take-up rack. The clamp carrier function of the pick-up machine is to automatically discharge the finished board pallets.
