Description

Technical Field

[0001] This utility model belongs to the technical field of glue scraping devices, and specifically relates to a glue scraping device for processing fabric core layered conveyor belts. Background Technology

[0002] During bonding, splicing, or vulcanization, adhesive may overflow from between layers or edges under pressure, forming phenomena such as glue nodules (local bulges) and flowing adhesive (irregular accumulation on the surface). If not scraped off, this will cause impact noise between the conveyor belt and rollers and idlers during operation, and stress concentration in the splice area, which is prone to early cracking. Therefore, it is necessary to use an adhesive scraping device to scrape off the adhesive on the conveyor belt.

[0003] Most existing glue scraping devices use a scraper mounted on the lower end of a support frame to smooth the glue on the conveyor belt. While this meets the need for glue scraping, the scraper is fixed to the support frame, making it difficult to adjust its angle. Furthermore, glue viscosity, curing speed, and cover adhesive hardness vary greatly. Soft glues require a smaller scraping angle to avoid stringing or accumulation, while hard glues require a larger scraping angle to provide sufficient cutting force. The fixed scraper angle is limited and cannot accommodate different working conditions or adapt to different glue properties and process requirements, thus reducing equipment compatibility. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a scraping device for adhesive in the processing of fabric core layered conveyor belts. By setting a rotating plate, the rotating plate drives the scraper to rotate, thereby adjusting the scraping angle of the scraper. Different scraping angles are used for different adhesive states, thus flexibly adapting to different types of adhesive states and improving the applicability of the scraper.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a scraping device for adhesive in the processing of fabric core layered conveyor belts, including a base plate, support plates symmetrically arranged on the upper end of the base plate, a top plate commonly arranged on the upper end of the two support plates, a telescopic push rod arranged on the upper end of the top plate, a fixed frame arranged on the telescopic end of the telescopic push rod extending to the lower end of the top plate, a rotating rod rotatably arranged inside the fixed frame, both ends of the rotating rod extending to the front and rear sides of the fixed frame and connected to rotating plates, a scraper detachably connected between the two rotating plates, and a driving component for driving the rotating rod to rotate inside the fixed frame.

[0006] As a further improvement of this utility model, the driving component includes a worm gear disposed in the middle of the fixed frame, a worm wheel that meshes with the worm gear disposed in the middle of the rotating rod, a motor disposed at the left end of the fixed frame, and the output end of the motor being connected to the worm gear through a coupling.

[0007] As a further improvement of this utility model, a fixing member for fixing the scraper is provided on the side wall of the rotating plate. The fixing member includes a mounting bracket provided on the side wall of the rotating plate. A slider is slidably arranged inside the mounting bracket. A plug rod is provided at one end of the slider near the scraper. A slot adapted to the plug rod is opened on the side wall of the scraper.

[0008] As a further improvement of this utility model, several springs are provided between the side wall of the slider and the inner side wall of the mounting bracket.

[0009] As a further improvement of this utility model, a pull rod is provided on the side wall of the slider, the pull rod is slidably connected to the side wall of the mounting bracket, and a pull ring is provided on the pull rod extending to the outside of the mounting bracket.

[0010] As a further improvement of this utility model, a limiting rod is provided at the upper end of the fixing frame, and a limiting plate is provided at the upper end of the limiting rod extending to the upper end of the top plate. The limiting rod is slidably connected to the top plate.

[0011] As a further improvement of this utility model, a number of support bases are evenly arranged at the lower end of the base plate, and anti-slip stripes are provided on the bottom outer wall of each support base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by setting up a rotating plate, the rotating rod drives the rotating plate to rotate, which in turn drives the scraper to rotate, thereby adjusting the scraping angle of the scraper. The adhesives used in the processing of fabric core conveyor belts (such as bonding adhesives and cover adhesives) exhibit different physical properties at different stages. When scraping off uncured soft adhesive, the angle can be adjusted to scrape lightly and smoothly. When scraping off semi-cured adhesive, it can cut precisely and remove it completely. When scraping off cooled and hardened adhesive, it can cut with a large angle and force, thus flexibly adapting to different types of adhesive states and improving the applicability of the scraper.

[0013] Secondly, by setting up inserts and slots, the scraper can be easily disassembled. As a vulnerable part that comes into direct contact with the glue, the scraper will experience wear and dulling of the cutting edge, chipping due to hard glue nodules, and surface glue curing during long-term use, which will affect the scraping effect. If disassembly is cumbersome (requiring multiple screws and special tools), it will take 10 to 20 minutes to replace. If a quick-release structure (such as a snap-fit) is adopted, the replacement can be completed within 30 seconds, reducing the downtime for single model change or maintenance by more than 80%, significantly improving the overall efficiency of the equipment.

[0014] Thirdly, by setting a limiting rod, which is slidably connected to the top plate, the fixed frame typically carries the scraper, pressure plate, slider, and other actuators, and performs strictly linear motion (usually up and down) under the action of the telescopic push rod. Without guidance, lateral forces, uneven loads, or vibrations can easily cause the frame to sway, the scraper / pressure plate to tilt, movement to jam, or increased wear. The limiting rod, as a high-rigidity guide column, cooperates with the linear bearing or wear-resistant bushing on the top plate to force the fixed frame to slide only in the vertical direction, eliminating lateral displacement and rotational degrees of freedom, thereby making the movement trajectory precise and controllable, ensuring uniform scraping pressure, parallel pressing surfaces, and consistent grinding gaps.

[0015] Fourth, by setting anti-slip stripes, the equipment may be subjected to the following external forces during operation: the reaction force of the grinding / scraping mechanism and the horizontal tension generated by the tension of the conveyor belt. The anti-slip stripes, by adding concave and convex textures to the bottom of the support base, greatly increase the static friction coefficient between the equipment and the ground (concrete, steel plate, floor tile, etc.), effectively preventing the equipment from accidentally sliding, displacing or overturning during operation or transportation. This is especially important in scenarios where there are no anchor bolts for fixing or temporary deployment. Attached Figure Description

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2 As shown in Figure 3, a device for scraping off adhesive used in processing fabric core layered conveyor belts includes a base plate 101. Support plates 102 are symmetrically arranged on the upper end of the base plate 101. A top plate 103 is arranged on the upper end of the two support plates 102. A telescopic push rod 104 is arranged on the upper end of the top plate 103. A fixed frame 105 is arranged at the telescopic end of the telescopic push rod 104 extending to the lower end of the top plate 103. A rotating rod 106 is rotatably arranged inside the fixed frame 105. Both ends of the rotating rod 106 extend to the front and rear sides of the fixed frame 105 and are connected to rotating plates 107. A scraper 108 is detachably connected between the two rotating plates 107. A driving component for driving the rotating rod 106 to rotate is arranged inside the fixed frame 105.

[0021] like Figure 2 , 3 As shown, the driving component includes a worm gear 109 disposed in the middle of the fixed frame 105, a worm wheel 110 meshing with the worm gear 109 disposed in the middle of the rotating rod 106, and a motor 111 disposed at the left end of the fixed frame 105. The output end of the motor 111 is connected to the worm gear 109 via a coupling. When the motor 111 is started, the output end of the motor 111 drives the worm gear 109 to rotate, the worm gear 109 drives the worm wheel 110 to rotate, the worm wheel 110 drives the rotating rod 106 to rotate, and the rotating rod 106 drives the rotating plate 107 to rotate. The rotating plate 107 drives the scraper 108 to rotate, thereby adjusting the scraping angle of the scraper 108. The adhesives used in the processing of fabric core conveyor belts (such as bonding adhesives and cover adhesives) exhibit different physical properties at different stages. When scraping off uncured soft adhesive, the angle can be adjusted to scrape lightly and smoothly. When scraping off semi-cured adhesive, it can cut precisely and remove it completely. When scraping off cooled and hardened adhesive, it can cut with a large angle and force. This allows for flexible application to different types of adhesive states and improves the applicability of the scraper 108.

[0022] like Figure 2 , 3 As shown, a fixing member for fixing the scraper 108 is provided on the side wall of the rotating plate 107. The fixing member includes a mounting bracket 201 provided on the side wall of the rotating plate 107. A slider 202 is slidably provided inside the mounting bracket 201. A plug rod 203 is provided at one end of the slider 202 near the scraper 108. A slot 204 adapted to the plug rod 203 is provided on the side wall of the scraper 108.

[0023] like Figure 3 As shown, several springs 205 are provided between the side wall of the slider 202 and the inner side wall of the mounting bracket 201.

[0024] like Figure 3As shown, a pull rod 206 is provided on the side wall of the slider 202. The pull rod 206 is slidably connected to the side wall of the mounting bracket 201. The pull rod 206 extends to the outside of the mounting bracket 201 and is provided with a pull ring. When it is necessary to disassemble the scraper 108, first pull the pull ring. The pull ring drives the pull rod 206, and the pull rod 206 drives the slider 202 to move. In turn, the slider 202 drives the insertion rod 203 to move. The insertion rod 203 disengages from the inside of the slot 204, making it convenient for the operator to remove the scraper 108. When it is necessary to fix the scraper 108, first place the scraper 108 at the lower end of the two rotating plates 107, and slide the scraper 108 towards the upper end of the rotating plates 107. During the sliding process, gently pull the pull ring. The pull ring drives the pull rod 206, and the pull rod 206 moves to the upper end of the mounting bracket 201. 6. The slider 202 drives the insertion rod 203 to move, so that the side wall of the insertion rod 203 abuts against the side wall of the scraper 108. The scraper 108 continues to move towards the upper end of the rotating plate 107 until the insertion rod 203 is inserted into the slot 204 under the action of the spring 205, which facilitates the disassembly of the scraper 108. As a vulnerable part that directly contacts the glue, the scraper 108 will experience wear and dulling of the cutting edge, chipping due to hard glue nodules, and surface glue curing during long-term use, which will affect the glue scraping effect. If disassembly is cumbersome (such as requiring multiple screws and special tools), it will take 10 to 20 minutes to replace. If a quick-release structure (such as a snap-fit) is adopted, the replacement can be completed within 30 seconds, reducing the downtime for single model change or maintenance by more than 80%, significantly improving the overall efficiency of the equipment.

[0025] like Figure 1 , 4 As shown, a limiting rod 207 is provided at the upper end of the fixed frame 105. The upper end of the limiting rod 207 extends to the upper end of the top plate 103, where a limiting plate is provided. The limiting rod 207 is slidably connected to the top plate 103. The fixed frame 105 typically carries the scraper 108, pressure plate, slider 202, and other actuators. Under the action of the telescopic push rod 104, it performs a strictly linear motion (usually up and down). Without guidance, lateral forces, uneven loads, or vibrations can easily cause the frame to shake, the scraper 108 / pressure plate to tilt, movement to jam, or increased wear. The limiting rod 207, as a high-rigidity guide post, cooperates with the linear bearing or wear-resistant bushing on the top plate 103 to force the fixed frame 105 to slide only in the vertical direction, eliminating lateral displacement and rotational freedom, thereby making the movement trajectory precise and controllable, ensuring uniform scraping pressure, parallel pressing surfaces, and consistent grinding gaps.

[0026] like Figure 1 , 4 As shown, several support bases 208 are evenly arranged at the lower end of the base plate 101.

[0027] In use, first adjust the angle of the scraper 108 according to the type of adhesive, then start the motor 111. The output of the motor 111 drives the worm gear 109 to rotate, the worm gear 109 drives the worm wheel 110 to rotate, the worm wheel 110 drives the rotating rod 106 to rotate, and the rotating rod 106 drives the rotating plate 107 to rotate. The rotating plate 107 drives the scraper 108 to rotate, thereby adjusting the scraping angle of the scraper 108. The adhesives used in the processing of the fabric core conveyor belt (such as bonding adhesives and cover adhesives) exhibit different physical properties at different stages. When scraping off uncured soft adhesive, the angle can be adjusted to scrape lightly and smoothly. When scraping off semi-cured adhesive, it can cut precisely and remove it completely. When scraping off cooled and hardened adhesive, it can cut with a large angle and force. This allows for flexible application to different types of adhesive states, improving the applicability of the scraper 108. The fabric core layered conveyor belt to be scraped is conveyed to the lower end of the scraper 108 through the conveying device. The conveyor belt is moved to move along the lower side wall of the scraper 108, thereby scraping off the adhesive on the conveyor belt.

[0028] When the scraper 108 needs to be disassembled, first pull the pull ring. The pull ring drives the pull rod 206, which in turn moves the slider 202. This causes the slider 202 to move the insertion rod 203, disengaging it from the slot 204, thus facilitating the removal of the scraper 108. When the scraper 108 needs to be fixed, first place the scraper 108 at the lower end of the two rotating plates 107 and slide it towards the upper end of the rotating plates 107. During this sliding process, gently pull the pull ring. The pull ring drives the pull rod 206, which in turn moves the insertion rod 203 via the slider 202, causing the side wall of the insertion rod 203 to contact the scraper 108. The scraper 108 continues to move towards the upper end of the rotating plate 107 as the side wall of 8 abuts against each other until the insertion rod 203 is inserted into the slot 204 under the action of the spring 205, thus facilitating the disassembly of the scraper 108. As a vulnerable part that directly contacts the glue, the scraper 108 will experience wear and dulling of the cutting edge, chipping due to hard glue nodules, and surface glue curing during long-term use, which will affect the scraping effect. If disassembly is cumbersome (such as requiring multiple screws or special tools), it will take 10 to 20 minutes to replace. If a quick-release structure (such as a snap-fit) is adopted, the replacement can be completed within 30 seconds, reducing the downtime for single model change or maintenance by more than 80%, significantly improving the overall efficiency of the equipment.

[0029] According to another embodiment of the present invention, such as Figure 1 , 4As shown, anti-slip stripes are provided on the bottom outer wall of the support base 208. During operation, the equipment may be subjected to the following external forces: the reaction force of the grinding / scraping mechanism and the horizontal tension generated by the tension of the conveyor belt. The anti-slip stripes, by adding concave and convex textures to the bottom of the support base 208, greatly increase the static friction coefficient between the equipment and the ground (concrete, steel plate, floor tile, etc.), effectively preventing the equipment from accidentally sliding, displacing or overturning during operation or transportation. This is especially important in scenarios where there are no anchor bolts for fixing or temporary deployment.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
