[0004] However, the automatic feeding device disclosed in the above patent still has certain inconveniences in practical applications. Since the production of high-performance adhesives requires high-quality control of raw material quality, when adding some solid granular or powdered raw materials, it is generally necessary to screen the raw materials to filter out impurities and substandard raw materials. However, the automatic feeding device disclosed in the above patent does not have the function of screening and filtering raw materials, which makes it difficult to meet the production needs of high-performance adhesives. Utility Model Content

[0005] The purpose of this invention is to provide an automatic feeding device for the production of high-performance adhesives, so as to solve the problem mentioned in the background art that the existing automatic feeding devices do not have the function of screening and filtering raw materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for the production of high-performance adhesives, comprising an automatic feeding box, wherein crossbars are provided in the inner cavities on both the front and rear sides of the automatic feeding box, and the two ends of the crossbars are respectively fixed to the left and right side walls of the inner cavity of the automatic feeding box. A sliding groove is provided on the top wall of the left end of the crossbar, and a sliding block is slidably connected in the groove cavity at one end of the sliding groove. A spring is fixedly connected between the right side wall of the sliding block and the right side wall of the groove cavity of the sliding groove. A screening plate is provided in the inner cavity of the automatic feeding box, and the bottom walls on both sides of the screening plate are respectively fixedly connected to the top walls of the two sliding blocks. A driving assembly is provided on one side wall of the automatic feeding box. The drive assembly includes two horizontal plates fixedly installed on the left side wall of the automatic feeding box. A rotating rod is rotatably connected between the two horizontal plates. The bottom end of the rotating rod passes through the bottom horizontal plate. A motor is fixed on the top wall of the top horizontal plate. The output end of the motor is connected to the top end of the rotating rod via a coupling. The drive assembly also includes an eccentric cam fixedly installed on the surface of the middle part of the rotating rod. A rectangular through slot adapted to the eccentric cam is provided on the left side wall of the automatic feeding box. The eccentric cam, the rectangular through slot, and the screening plate are all located on the same horizontal plane. A hollow box is provided at the bottom of the screening plate. The left end of the hollow box passes through the left side wall of the automatic feeding box. A discharge cylinder communicating with the inner cavity of the automatic feeding box is fixed on the bottom wall of the automatic feeding box. A spiral conveying rod is provided in the cylinder. The top end of the spiral conveying rod passes through the right bottom wall of the hollow box via a bearing and extends into the inner cavity of the hollow box.

[0007] Preferably, pulleys are fixedly installed on the top surface of the spiral conveyor rod and the bottom surface of the rotating rod, and a belt is sleeved between the two pulleys.

[0008] Preferably, the automatic feeding box has feeding hoppers fixed on both sides of its top wall that communicate with the inner cavity of the automatic feeding box, and guide plates that are placed at an inclination are fixedly installed on both sides of the inner cavity of the automatic feeding box. The guide plates are located on top of the screening plate, and the front wall of the automatic feeding box is equipped with a door.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This invention involves adding solid granular or powdered raw materials required for adhesive production into an automatic feeding box via a feeding hopper. Under the action of a guide plate, the raw materials automatically fall into a screening plate. As the motor starts, it drives a rotating rod to rotate, which in turn drives an eccentric cam to rotate. When the eccentric cam rotates, it contacts the screening plate through a rectangular slot, pushing the screening plate to the right. During this rightward movement, the screening plate causes a sliding block to move along a sliding groove to the right, compressing a spring. When the eccentric cam rotates to the other side, it temporarily ceases to push the screening plate, allowing the screening plate to move under the elastic force of the spring. The eccentric cam moves to the left to achieve automatic reset. With the continuous rotation of the eccentric cam and the action of the spring, the screening plate can move continuously left and right, thus screening and filtering the raw materials. The screened and filtered materials fall to the bottom of the automatic feeding box and are then introduced into the adhesive production equipment through the discharge cylinder. Driven by the pulley and belt, the rotating rod rotates, driving the screw conveyor to rotate as well. The rotation of the screw conveyor ensures stable discharge of the screened raw materials, preventing blockages. By refining the raw materials through screening, the quality of the adhesive production raw materials is improved, which is beneficial for the production of high-performance adhesives.

A screening plate 14 is disposed in the inner cavity of the automatic feeding box 1, the front and rear bottom walls of the screening plate 14 are respectively welded to the top walls of the two sliding blocks 16, and a drive assembly is disposed on the left side wall of the automatic feeding box 1.

[0014] The drive assembly includes two horizontal plates 4 welded to the left side wall of the automatic feeding box 1. The top end of the rotating rod 7 is rotatably mounted on the top horizontal plate 4 via a bearing, and the bottom end of the rotating rod 7 passes through the bottom horizontal plate 4 via a bearing. The motor 5 is fixed to the top wall of the top horizontal plate 4 by screws, and the output end of the motor 5 is connected to the top end of the rotating rod 7 via a coupling. The drive assembly also includes an eccentric cam 8 welded to the surface of the middle part of the rotating rod 7. A rectangular through slot 6 adapted to the eccentric cam 8 is provided on the left side wall of the automatic feeding box 1 to allow the eccentric cam 8 to rotate normally. The eccentric cam 8, the rectangular through slot 6, and the screening plate 14 are all located on the same horizontal plane to allow the eccentric cam 8 to push the screening plate 14 to move during rotation. A hollow box 9 is located at the bottom of the screening plate 14, and the left end of the hollow box 9 passes through the left side wall of the automatic feeding box 1. The hollow box 9 is welded to the left side wall of the automatic feeding box 1. The bottom wall of the automatic feeding box 1 is welded with a discharge cylinder 18 that communicates with the inner cavity of the automatic feeding box 1 for discharging material. The screw conveyor 19 is set in the cylinder of the discharge cylinder 18. The top end of the screw conveyor 19 passes through the bottom wall of the right end of the hollow box 9 via a bearing and extends into the inner cavity of the hollow box 9. The top wall of the hollow box 9 is conical, which is intended to prevent the raw material falling after screening from accumulating on the top wall of the hollow box 9. Both the top surface of the spiral conveyor rod 19 and the bottom surface of the rotating rod 7 are welded with pulleys 10. A belt 11 is sleeved between the two pulleys 10. The top walls of the left and right sides of the automatic feeding box 1 are welded with feeding hoppers 3 that communicate with the inner cavity of the automatic feeding box 1. The left and right sides of the inner cavity of the automatic feeding box 1 are welded with inclined guide plates 12. The guide plates 12 are located on the top of the screening plate 14. The door 2 is installed on the front wall of the automatic feeding box 1. Its purpose is to facilitate opening the automatic feeding box 1 and cleaning up the unqualified raw materials remaining on the screening plate 14.

[0015] In use, solid granular or powdered raw materials required for adhesive production are added to the automatic feeding box 1 through the feeding hopper 3. Under the action of the guide plate 12, the raw materials automatically fall into the screening plate 14. As the motor 5 starts, the motor 5 drives the rotating rod 7 to rotate, and the rotating rod 7 drives the eccentric cam 8 to rotate. When the eccentric cam 8 rotates, it touches the screening plate 14 through the rectangular through groove 6, pushing the screening plate 14 to the right. During the movement of the screening plate 14 to the right, it drives the sliding block 16 to move to the right along the sliding groove 15, so that the sliding block 16 compresses the spring 17. When the eccentric cam 8 turns to the other side, it temporarily no longer pushes the screening plate 14, so that the screening plate 14 is under the elastic force of the spring 17. Under the action of the automatic leftward movement, the eccentric cam 8 and the spring force of the spring 17 work together to make the screening plate 14 move left and right continuously, thereby screening and filtering the raw materials. The screened and filtered raw materials fall to the bottom of the automatic feeding box 1 and can be introduced into the adhesive production equipment through the discharge cylinder 18 for adhesive production. Under the transmission action of the pulley 10 and the belt 11, the rotating rod 7 rotates and drives the screw conveyor 19 to rotate together. When the screw conveyor 19 rotates, the screened raw materials can be discharged stably to avoid blockage. By screening and refining the raw materials, the quality of the raw materials for adhesive production is improved, which is beneficial to the production of high-performance adhesives.
