Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and more specifically, to a dual-station alternating feeding mechanism for a sandpaper adhesive coating machine. Background Technology

[0002] Sponge sandpaper is an extended type of sandpaper. In the production process of sponge sandpaper, an adhesive application process is required. During the feeding process of sponge sandpaper, a gantry frame structure is often used for adhesive application. During the adhesive application process, a glue gun needs to be used to apply the adhesive close to the sponge.

[0003] Although existing sandpaper has an automatic structure to assist in the movement of the adhesive during the coating process, it lacks a limiting mechanism for the sandpaper. During the movement, the sandpaper is prone to deviation due to the pushing force and surface friction, resulting in skewed adhesive application.

[0004] A search revealed a Chinese patent with publication number CN216883441U that discloses a gluing device for producing sponge sandpaper. This utility model utilizes the conveying characteristics of rollers to linearly and smoothly push the sandpaper through the gluing frame. The batch gluing mechanism set on the gluing frame uses gravity in conjunction with a threaded feeding mechanism to ensure that the material can be stably and quantitatively pushed to each nozzle through the threaded feeding method, thus ensuring the uniformity of the spraying.

[0005] However, in actual use, after a roll of sandpaper is coated with glue, the sandpaper roller needs to be disassembled and replaced, and the machine needs to be stopped to feed a new roll of sandpaper. The glue coating head of the glue coating machine will be idle, resulting in low glue coating efficiency. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dual-station alternating feeding mechanism for a sandpaper coating machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dual-station alternating feeding mechanism for a sandpaper coating machine includes a base frame. Two supports are fixedly connected to one side of the base frame, and a rotating roller is rotatably connected to the inner side of each support. Two fixed seats are fixedly connected to the top of the base frame, and two pins are slidably connected to the inner side of each fixed seat. A connecting plate is fixedly connected to one side of each pin. An alternating mechanism is provided on the outer side of the rotating roller. The alternating mechanism includes two connecting rods, the inner side of which is fixedly connected to the outer side of the rotating roller. A concentrating roller is rotatably connected to both ends of the connecting rods. A collecting cylinder is slidably connected to the outer side of the concentrating roller. Two sliders are fixedly connected to the inner side of the collecting cylinder, and the outer sides of the sliders slide against the inner side of the concentrating roller. The system is dynamically connected, with a retaining ring at one end of the central roller, a socket inserted into one side of the connecting rod, two bolts threadedly connecting the outer side of the socket to the inner side of the connecting rod, a load-bearing frame fixedly connected to the top of the base frame, a receiving plate fixedly connected to the inner side of the load-bearing frame, two receiving rollers rotatably connected to the outer side of the receiving plate, a servo motor fixedly connected to the top of the base frame, two transmission rollers rotatably connected to the inner side of the load-bearing frame, one end of which is fixedly connected to the output end of the servo motor, two transmission belts drivingly connected to the outer side of the transmission roller, and multiple guide rollers fixedly connected to the inner side of the load-bearing frame; an adhesive application mechanism is provided on the outer side of the base frame.

[0009] By adopting the above technical solution: using two connecting rods to deflect the concentrating roller and the collecting cylinder, the two collecting cylinders can be rotated, allowing them to assist in the unwinding of the sandpaper. At the same time, multiple guide rollers are used to assist in guiding the edge of the sandpaper, keeping the adhesive coating on the sandpaper flat.

[0010] As a further description of the above technical solution: the adhesive application mechanism includes a liquid storage tank, the bottom of which is fixedly connected to the top of the base frame, a water inlet pipe is connected to the top of the liquid storage tank, a guide block is fixedly connected to the inside of the water inlet pipe, a water pipe is connected to the bottom of the liquid storage tank, two gear pumps are installed on the outside of the water pipe, and multiple nozzles are fixedly connected to the bottom of the water pipe.

[0011] By adopting the above technical solution, two gear pumps and guide blocks are used to allow the glue to be input into the inside of the water pipe in opposite directions, so that the glue can maintain effective pressure and be sprayed onto the sandpaper surface through multiple nozzles.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up an alternating mechanism, compared with the existing technology, two centralized rollers and a collecting cylinder are quickly disassembled on the outside of the connecting rod, so that the two centralized rollers can drive multiple collecting cylinders and sandpaper to perform dual-station alternating feeding, so that the two sandpapers can maintain a stable feeding efficiency, and multiple guide rollers are used to guide the edge of the sandpaper, so that the sandpaper is smoothly conveyed inside the glue coating machine and maintains stable operation continuity.

[0014] 2. By setting up an adhesive application mechanism, compared with the existing technology, the inclined setting of the guide block surface allows the adhesive to flow naturally to the water pipe inside the liquid storage tank by gravity, reducing adhesive residue in the corners or edges of the liquid storage tank and improving adhesive utilization.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The embodiments disclosed in this application are as follows: Figure 1-6The dual-station alternating feeding mechanism of a sandpaper coating machine shown includes a base frame 1. Two supports 2 are fixedly connected to one side of the base frame 1. A rotating roller 3 is rotatably connected to the inner side of the supports 2. Two fixed seats 4 are fixedly connected to the top of the base frame 1. Two pins 5 are slidably connected to the inner side of the fixed seats 4. A connecting plate 6 is fixedly connected to one side of the pins 5. An alternating mechanism is provided on the outer side of the rotating roller 3. The alternating mechanism includes two connecting rods 7. The inner side of the connecting rods 7 is fixedly connected to the outer side of the rotating roller 3. A concentrating roller 8 is rotatably connected to both ends of the connecting rods 7. A collecting cylinder 9 is slidably connected to the outer side of the concentrating roller 8. Two sliders 10 are fixedly connected to the inner side of the collecting cylinder 9. The outer side of the sliders 10 is slidably connected to the inner side of the concentrating roller 8. One end is fitted with a retaining ring 11, and a socket 19 is inserted into one side of the connecting rod 7. Two bolts 20 are threadedly connected to the outer side of the socket 19 and the inner side of the connecting rod 7. A load-bearing frame 12 is fixedly connected to the top of the base frame 1. A receiving plate 13 is fixedly connected to the inner side of the load-bearing frame 12. Two receiving rollers 14 are rotatably connected to the outer side of the receiving plate 13. A servo motor 15 is fixedly connected to the top of the base frame 1. Two transmission rollers 16 are rotatably connected to the inner side of the load-bearing frame 12. One end of one of the transmission rollers 16 is fixedly connected to the output end of the servo motor 15. Two transmission belts 17 are drively connected to the outer side of the transmission roller 16. Multiple guide rollers 18 are fixedly connected to the inner side of the load-bearing frame 12. A glue application mechanism is provided on the outer side of the base frame 1.

[0024] By utilizing the sliding of the two sockets 19 on the outside of the connecting rod 7, the concentrating roller 8 can be removed from the inside of the connecting rod 7 during its rotation inside the connecting rod 7. Then, by removing the retaining ring 11, the collecting cylinder 9 can be removed from the outside of the concentrating roller 8, and a new uncoated collecting cylinder 9 and sandpaper can be replaced. This allows the two connecting rods 7 to be swapped in opposite directions. The servo motor 15 drives the transmission roller 16 and the two transmission belts 17 to rotate, so that the two transmission belts 17 and multiple guide rollers 18 can transmit and guide the sandpaper in the adhesive coating process.

[0025] Reference Figure 1 and Figure 6 As shown, the adhesive application mechanism includes a liquid storage tank 21. The bottom of the liquid storage tank 21 is fixedly connected to the top of the base frame 1. A water inlet pipe 22 is connected to the top of the liquid storage tank 21. A guide block 23 is fixedly connected to the inner side of the water inlet pipe 22. A water pipe 24 is connected to the bottom of the liquid storage tank 21. Two gear pumps 25 are installed on the outer side of the water pipe 24. Multiple nozzles 26 are fixedly connected to the bottom of the water pipe 24. The guide block 23 guides the adhesive so that the low-level adhesive can always accumulate at the water inlet end of the water pipe 24. Then, the two gear pumps 25 transfer the adhesive so that the adhesive can be sprayed onto the sandpaper surface through the multiple nozzles 26.

[0026] The working principle of this utility model is as follows: During the application of adhesive to the sandpaper, firstly, the two connecting plates 6 are pulled, causing the corresponding two pins 5 to slide inside the fixed seat 4. Then, the two connecting rods 7 are pushed, causing the concentrating roller 8 and the collecting cylinder 9 to deflect, so that one of the collecting cylinders 9 moves to one side of the load-bearing frame 12. Then, one end of the sandpaper is placed on the top of the two transmission belts 17. After that, one end of the sandpaper passes through the load-bearing frame 12 and multiple guide rollers 18, connecting one end of the sandpaper to the subsequent processing mechanism. The subsequent processing mechanism pulls the sandpaper, and simultaneously... The servo motor 15 drives one of the transmission rollers 16 to drive the two transmission belts 17 and the other transmission roller 16, so that the two transmission belts 17 can drive the bottom of the sandpaper to a certain extent. At the same time, the guide block 23 inside the liquid storage tank 21 guides the glue, so that the glue can flow to both ends of the water pipe 24. Then, the two gear pumps 25 suck in the two ends of the water pipe 24, so that the glue flows through the water pipe 24 to multiple nozzles 26 at the bottom of the two water pipes 24, and then sprays the glue out through the multiple nozzles 26, so that the glue is sprayed onto the surface of the sandpaper.

[0027] After the sandpaper on the outside of one of the collection cylinders 9 is coated, the two connecting rods 7 are deflected so that the uncoated sandpaper on the outside of the other concentrating roller 8 and the collection cylinder 9 is moved to one side of the support frame 12. The sandpaper on the outside of the collection cylinder 9 is then placed on the top of the support frame 12, and the glue spraying continues. The multiple sockets 19 are rotated out from one side of the two connecting rods 7. Then the concentrating roller 8 and the collection cylinder 9 are removed from the inside of the connecting rod 7. The retaining ring 11 on one side is pulled out from the outside of the concentrating roller 8. Then the collection cylinder 9 is guided by the slider 10 so that it can slide out from the inside of the concentrating roller 8. Then another uncoated sandpaper and collection cylinder 9 are replaced, and the collection cylinder 9 is reinserted into the outside of the concentrating roller 8 for alternating coating.
