[0002] When producing wooden pallets, it is necessary to set up an assembly mechanism and a feeding mechanism. The assembly mechanism uses a robot to grab the boards delivered by the feeding mechanism and place them at the specified position according to the program, and then nail and assemble them. The feeding mechanism delivers the processed semi-finished wooden boards to the assembly station one by one. The existing feeding mechanism manually puts the boards between two feeding wheels one by one, and then drives the two feeding wheels to rotate through a motor to deliver the boards to the assembly mechanism in sequence. This feeding method cannot achieve continuous feeding in the true sense, and can only be fed manually. During the feeding process, the physical strength is consumed, which leads to a decrease in feeding efficiency, and also increases the labor intensity of the staff.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] See attached Figure 1-5 , shown is a plate continuous feeding mechanism, including a material guide unit 1 and a feeding unit 2, specifically, the material guide unit 1 includes a frame 3, a plurality of slide rails 5 are vertically arranged on the frame 3, the frame 3 is slidably connected to a mounting plate 4 through the slide rails 5, the frame 3 is sequentially provided with a feed wheel group and a feeding wheel group along the length direction through the mounting plate 4, wherein the feed wheel group includes a first material guide roller 8 and a second material guide roller 9 arranged up and down, the first material guide roller 8 and the second material guide roller 9 are located on the other side of the frame 3 and a first reducer 17 is provided, When in use, the first reducer 17 drives the first guide roller 8 and the second guide roller 9 to rotate toward each other, wherein the second guide roller 9 is mounted on the frame 3, and a connecting seat 21 is bolted to the position of the mounting plate 4 close to the first guide roller 8, one end of the connecting seat 21 is hinged with a connecting arm 22, and the end of the connecting arm 22 away from the connecting seat 21 is hinged to the outer wall of the roller sleeve of the first guide roller 8, and a pressure wheel cylinder 23 is installed on one side of the connecting seat 21, and the output end of the pressure wheel cylinder 23 is hinged to the outer wall of the roller sleeve of the first guide roller 8 In addition, a waist hole is vertically opened at the roller shaft position of the first guide roller 8 of the frame 3, so that the first guide roller 8 is driven by the pressure wheel cylinder 23 to realize the elastic setting on the mounting plate 4. In addition, in order to improve the stability of the first guide roller 8, a guide component 24 that follows the elastic action of the pressure wheel cylinder 23 is also provided on the first guide roller 8. More importantly, the first guide roller 8 is a conical structure, and the first guide roller 8 and the second guide roller 9 are both provided with a feeding thread 10. When in use, the plate is transported to the feeding wheel group through the feeding unit 2. Since the moving direction of the plate on the feeding unit 2 is perpendicular to the moving direction on the guide unit 1, an inward thrust must be applied to the plate in order to place the plate between the first guide roller 8 and the second guide roller 9. Therefore, based on this premise, the plate can be automatically screwed between the first guide roller 8 and the second guide roller 9 through the feeding thread 10 on the first guide roller 8 and the second guide roller 9, which replaces manual feeding, and then the plate is transported forward under the action of the first reducer 17;

[0030] In addition, the end of the second guide roller 9 is also tapered, so the tapered structure on the first guide roller 8 and the second guide roller 9 makes the transition of the plate from the feeding unit 2 to the first guide roller 8 and the second guide roller 9 smoother, which is equivalent to providing a V-shaped channel for the feeding of the plate through the tapered structure, thereby increasing the passing width of the plate;

[0031] Furthermore, the feeding wheel group is provided with a first feeding roller 11 and a second feeding roller 12 above and below. The first feeding roller 11 and the second feeding roller 12 are provided with a second reducer 18 on the other side of the frame 3. The first reducer 17 and the second reducer 18 are connected to a driving motor 19 through a transmission shaft. Similarly, the second feeding roller 12 is also provided on the frame 3. At the same time, each first feeding roller 11 is also provided with a pressure roller cylinder 23. Therefore, by configuring the pressure roller cylinder 23 on the first guide roller 8 and the second guide roller 9, the first guide roller 8 and the first feeding roller 11 can realize dynamic fitting with the surface of the plate when conveying plates of different thicknesses, thereby ensuring the friction of the feeding wheel group and the feeding wheel group on the plate, avoiding slipping, and improving the feeding quality.

[0032] Furthermore, the frame 3 is provided with a blocking arm 13 between the feed wheel group and the feeding wheel group, and the blocking arm 13 includes a guide plate 15 parallel to the feeding direction of the feeding unit 2 and a limit plate 16 obliquely arranged at one end of the guide plate 15, and the limit plate 16 is in an arc structure. At the same time, the frame 3 is provided with a wall 14 at a position corresponding to the limit plate 16, and the spacing between the limit plate 16 and the wall 14 decreases along the moving direction of the plate. At the same time, an inlet 30 is formed between the end of the limit plate 16 and the wall 14, and the width of the inlet 30 can only accommodate the width of one plate, so that the plate can be restricted by the inlet 30. The plates pass through one by one in sequence. When in use, the plate is rotated between the first guide roller 8 and the second guide roller 9 under the action of the feeding screw thread 10, and the plate is pressed against the wall 14. Then, the plate is pressed against the wall 14 under the action of the first guide roller 8 and the second guide roller 9 rotating in opposite directions, and passes through the inlet 30. Then, the plate continues to reach the next process under the clamping action of the first feeding roller 11 and the second feeding roller 12. In this way, continuous mechanical feeding is realized by using the first guide roller 8 and the second guide roller 9 with the feeding screw thread 10 instead of manpower, thereby improving the feeding efficiency and reducing the labor intensity.

[0033] Further, the feeding unit 2 includes a feeding frame 25, a plurality of bearing beams 26 are arranged side by side on the top of the feeding frame 25, a feeding belt 28 is arranged on each bearing beam 26, and a feeding shaft 27 is arranged at the bottom of the plurality of bearing beams 26, the feeding belt 28 and the feeding shaft 27 are linked by gears, and a feeding motor 29 is arranged at the inner bottom of the feeding frame 25, the output end of the feeding motor 29 is linked with the feeding shaft 27 through a belt, and when in use, the feeding motor 29 is linked with the feeding shaft 27 to drive the feeding belt 28 to convey the horizontally placed plates;

[0034] At the same time, in order to make the transition of the plate between the feeding unit 2 and the feeding wheel set more stable, the length of the second guide roller 9 is greater than that of the first guide roller 8, and an overlap area is provided between the second guide roller 9 and one end of the load-bearing beam 26. In this overlap area, there is both the spiral force of the feed thread 10 on the plate inward and the forward thrust of the feed belt 28 on the plate, so that the plate is more easily introduced between the first guide roller 8 and the second guide roller 9, and jamming during transportation is also avoided;

[0035] Furthermore, a lifting motor 6 is provided at the bottom of the frame 3, and the lifting motor 6 is provided with a lead screw 7 through a connecting rod, and one end of the lead screw 7 is rotatably connected to the mounting plate 4. When in use, the lifting motor 6 can use the lead screw 7 to adjust the spacing between the first guide roller 8 and the second guide roller 9, thereby facilitating the conveying of plates of different thicknesses.

[0036] Furthermore, in order to reduce the jumping of the plate on the conveyor belt 28 , a pressing arm 20 is provided on the frame 3 , and the pressing arm 20 can limit the longitudinal jumping of the plate on the conveyor belt 28 .

[0037] When in use, the plates are placed one by one horizontally side by side on the conveyor belt 28, and the conveyor motor 29 is started to transport the plates to the guide wheel group through the conveyor belt 28. Then, under the action of the feed thread 10 of the first guide roller 8 and the second guide roller 9, the plates are screwed between the two and pressed against the wall 14. Then, under the action of the opposite rotation of the first guide roller 8 and the second guide roller 9, the plates enter one by one from the feed port 30 between the first feeding roller 11 and the second feeding roller 12, and finally reach the next process under the action of the second reducer 18.

[0038] The above description is only a preferred specific implementation method of the present utility model, and does not limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
