[0002] With the development of the times, people's requirements for the quality of life have increased. In the field of decoration materials, wood veneer wall panels are deeply loved by consumers. Its production process mainly involves the automatic spiral feeder feeding the reasonably proportioned raw materials into the mixer for mixing, and then the automatic feeder feeds the mixed raw materials into the extrusion device. After melting at a certain temperature, it is extruded from the extrusion device to the extrusion die, and then shaped by the shaping die. After passing through the cooling bracket, it is evenly pulled by the eight-roller traction machine to the dust-free cutting unit, and finally automatically stacked by the robot.

[0003] At present, the main components of the wood veneer extruder on the market usually include a feeding system, an extrusion system, a mold system, and a shaping system. The feeding system is mainly composed of a funnel, a feeder and a conveyor, the extrusion system is mainly composed of a screw, a heater and a head, the mold system is mainly composed of a mold and a pouring system, and the shaping system is mainly composed of a cooling mechanism and a temperature control system. However, in actual use, after the produced board is cooled and shaped by the shaping system, the board is not immediately checked for bending, and the result is not reliable if it is only observed by the naked eye of the staff. If the produced board is bent and is not discovered in time and the equipment is not repaired and adjusted, it will not only affect the board production qualification rate but also cause material waste. Therefore, a wood veneer extruder is proposed. Utility Model Content

[0023] like Figures 1 to 4As shown, a wood veneer extruder comprises a feeding mechanism 1, an extrusion mechanism 2 is fixedly installed at the output end of the feeding mechanism 1, a mold 3 is fixedly installed at the output end of the extrusion mechanism 2, a cooling mechanism 4 is fixedly installed at the output end of the mold 3, two side panels 5 are arranged at the output end of the cooling mechanism 4, a plurality of rotatable conveying rollers 6 which are evenly distributed are arranged in the middle of the two side panels 5, a U-shaped frame 7 is fixedly installed on the two side panels 5, two electric telescopic rods 10 are arranged inside the U-shaped frame 7, a connecting rod 11 is fixedly installed at the output end of each electric telescopic rod 10, and an adjusting mechanism 12 is arranged at the ends of the two connecting rods 11 which are close to each other. Two U-shaped frames 13 are arranged on the side where the two adjustment mechanisms 12 are close to each other (in the technical solution, each group of adjustment mechanisms 12 can drive the two adjacent U-shaped frames 13 to move away from or close to each other), a cylinder 14 is fixedly installed on the side where the two adjacent U-shaped frames 13 are far away from each other, and a sensor 15 is fixedly installed on the inner side wall of each cylinder 14, and a circular hole 16 is opened on the side where the two adjacent U-shaped frames 13 are close to each other, and a round rod 17 is movably installed inside each circular hole 16, and a spring 18 is sleeved on the end where the two adjacent round rods 17 are close to each other, and a sensor 15 is fixed on the inner side wall of each cylinder 14, and a circular hole 16 is opened on the side where the two adjacent U-shaped frames 13 are close to each other. A rectangular plate 19 is installed, and an alarm 20 is fixedly installed on the top of each connecting rod 11 (in this technical solution, each alarm 20 is connected to two adjacent sensors 15 through a wireless signal). It should be noted that when the feeding mechanism 1 mixes the raw materials according to a certain proportion and then transports them to the extrusion mechanism 2, the extrusion mechanism 2 then fuses the materials into the inside of the mold 3, and finally the formed plate is cooled by the cooling mechanism 4. When the cooled plate comes out from the output end of the cooling mechanism 4, the edges of the two sides of the plate pass through the middle of each adjacent two rectangular plates 19 respectively. In advance, the staff can control the two electric telescopic rods 10 respectively. Each electric telescopic rod 10 can drive the corresponding connecting rod 11 to move up and down to a suitable height, and each connecting rod 11 drives the corresponding adjusting mechanism 12 to move synchronously to a suitable height, and each adjusting mechanism 12 drives the corresponding two rectangular plates 19 to move synchronously to a suitable height. If the plate is bent, the protrusion will push the rectangular plate 19 to the adjacent U-shaped frame 13 during transportation, and then the corresponding spring 18 is squeezed and the rectangular plate 19 drives the corresponding round rod 17 to contact the adjacent sensor 15. After the sensor 15 is contacted, it immediately sends a signal to the corresponding alarm 20, and the alarm 20 sends a warning to remind the staff to check in time.

It should be noted that the distance between each two adjacent rectangular plates 19 can be controlled according to the thickness of the plate. Specifically, it is only necessary to start the servo motor 1203, and the servo motor 1203 drives the corresponding threaded rod 1204 to reciprocate. The reciprocating rotation of the threaded rod 1204 can make the corresponding two movable blocks 1205 move away from or closer to each other. When moving, each movable block 1205 will drive the corresponding U-shaped frame 13, round rod 17, and rectangular plate 19 to move synchronously, so as to control the distance between each two adjacent rectangular plates 19.

[0025] like Figure 2 , Figure 3 , Figure 4 As shown, two square grooves 21 are provided on the side where each two adjacent rectangular plates 19 are close to each other, and a rotatable roller 22 is movably installed inside each square groove 21. It should be noted that when the edge of the plate passes between each two adjacent rectangular plates 19, each roller 22 can rotate due to the friction of the movement of the plate, so as to facilitate the transmission of the plate between each two adjacent rectangular plates 19.

[0026] like Figure 3 As shown, a mounting plate 23 is fixedly installed on one side where the two adjustment rods 1201 are close to each other, and an electric telescopic rod 24 is fixedly installed on one side where the two mounting plates 23 are close to each other. A marking pen 25 is fixedly installed on the output end of each electric telescopic rod 24 (in the present technical solution, each alarm 20 is connected to the adjacent electric telescopic rod 24 via a wireless signal). It should be noted that after each alarm 20 sounds an alarm, it immediately controls the output end of the corresponding electric telescopic rod 24 to drive the corresponding marking pen 25 to move toward the plate, marking it from the side of the plate to facilitate inspection by the staff.

[0027] like Figure 1 , Figure 2 As shown, a slide groove 8 is provided on the top of the U-shaped frame 7, and two sliders 9 are movably installed inside the slide groove 8. The top ends of two electric telescopic rods 10 are fixedly connected to the bottom ends of the two sliders 9 respectively. It should be noted that the positions of the two sliders 9 can be moved according to the width of the plate, and specifically, the sliders 9 only need to be pulled inside the slide groove 8.

[0028] like Figure 1 , Figure 2 As shown, strip holes 26 are provided on the symmetrical side walls inside the slide groove 8, and screw rods 27 are fixedly installed on the side walls of each slider 9. Each screw rod 27 passes through the corresponding strip hole 26, and each screw rod 27 is threadedly connected with a nut 28. It should be noted that when the slider 9 is moved to a suitable position, the position of the slider 9 can be fixed by rotating the corresponding two nuts 28 respectively.

[0029] In summary:

[0030] When the feeding mechanism 1 mixes the raw materials according to a certain proportion and then conveys them to the extrusion mechanism 2, the extrusion mechanism 2 then fuses the materials and squeezes them into the inside of the mold 3, and finally the formed plate is cooled by the cooling mechanism 4. When the cooled plate comes out from the output end of the cooling mechanism 4, the edges on both sides of the plate pass through the middle of each two adjacent rectangular plates 19 respectively. In advance, the staff can control the two electric telescopic rods 10 respectively, and each electric telescopic rod 10 can drive the corresponding connecting rod 11 to move up and down to a suitable height. Each connecting rod 11 then drives the corresponding adjustment mechanism 12 to move synchronously to a suitable height, and each adjustment mechanism 12 then drives the corresponding two rectangular plates 19 to move synchronously to a suitable height. If the plate is bent, the convex part will push the rectangular plate 19 to the adjacent U-shaped frame 13 during transportation, and then the corresponding spring 18 is squeezed and the rectangular plate 19 drives the corresponding round rod 17 to contact the adjacent sensor 15. After the sensor 15 is contacted, it immediately sends a signal to the corresponding alarm 20, and the alarm 20 sends a warning to remind the staff to check in time.
