Abstract
Description
Technical Field
[0001] This application relates to the field of glue valves, and more specifically, to a glue replacement valve designed to prevent clogging. Background Technology
[0002] A glue-changing valve is an automated industrial device used to precisely control the delivery of adhesives, sealants, or other fluid materials. It is primarily used in fields requiring high-precision dispensing or coating, such as electronics manufacturing, automotive assembly, medical devices, and packaging. Its core function is to achieve controllable distribution of fluid materials through precise opening and closing and flow regulation, ensuring process consistency and product quality. A glue-changing valve typically consists of a valve body, a drive mechanism (pneumatic, electric, or piezoelectric), a nozzle, a sealing assembly, and a control system. The workflow includes: pressure from the storage tank drives fluid into the valve chamber; the drive device triggers the valve core to open the flow channel; material is extruded through the nozzle; and when closed, a spring or reverse driving force resets and cuts off the flow.
[0003] After the current glue-changing valve is used, glue tends to adhere to the inner wall of the glue outlet tube, making it difficult to drain in time. This causes the glue to solidify on the inner wall of the glue outlet tube, resulting in blockage and affecting the use of the glue-changing valve, thus reducing the practicality of the device. Utility Model Content
[0004] To overcome the above shortcomings, this application provides an anti-clogging glue replacement valve, which aims to improve the problem that after the glue replacement valve is used, glue easily adheres to the inner wall of the glue outlet tube, making it difficult to discharge in time. This causes the glue to solidify on the inner wall of the glue outlet tube, resulting in blockage of the glue outlet tube, affecting the use of the glue replacement valve, and reducing the practicality of the device.
[0005] This application provides an anti-clogging adhesive replacement valve, including an adhesive inlet structure and a cleaning structure. The adhesive inlet structure includes two support plates and an adhesive inlet assembly, which is disposed within the support plates. The cleaning structure includes an adhesive replacement valve body, an adhesive outlet pipe, a pulling assembly, and a pushing column. The two support plates are arranged parallel to each other on one side of the adhesive replacement valve body. The adhesive inlet assembly is connected to the adhesive replacement valve body, and the adhesive outlet pipe is also connected to the adhesive replacement valve body. The pulling assembly is slidably connected to the adhesive replacement valve body, and the pushing column is connected to the pulling assembly and is in contact with the inner wall of the adhesive outlet pipe.
[0006] In one specific implementation, the glue inlet assembly includes a storage cylinder and a glue inlet pipe. The storage cylinder is fixedly connected to the support plate, and the two ends of the glue inlet pipe are respectively connected to the storage cylinder and the glue changing valve body.
[0007] In the above implementation process, the installation of the storage cylinder and the glue inlet pipe makes it convenient to supply glue to the glue changing valve body.
[0008] In one specific implementation, the pulling assembly includes a pull ring, a rotating ring, a connecting ring, and two L-shaped pull plates. The rotating ring is fixedly connected to the pull ring, and the rotating ring is rotatably connected to the connecting ring. Two L-shaped pull plates are fixedly connected to one side of the connecting ring. Both L-shaped pull plates are fixedly connected to the push column, and both L-shaped pull plates are slidably connected to the rubber changing valve body.
[0009] In the above implementation process, the pull ring, rotating ring, connecting ring and two L-shaped pull plates make it easy to pull and push the column to move.
[0010] In one specific implementation, a mounting ring is fixedly connected to one side of the rubber replacement valve body, and the rotating ring is threadedly connected to the mounting ring.
[0011] In the above implementation process, the rotating ring is threadedly connected to the mounting ring, which facilitates the fixed connection between the rotating ring and the body of the glue changing valve, and avoids the glue extrusion column being blocked by the glue squeezing and pushing when the glue changing valve body is in use.
[0012] In one specific implementation, a bearing is embedded in the connecting ring, and the rotating ring is interference-fitted with the inner ring of the bearing.
[0013] In the above implementation process, by using an interference fit between the rotating ring and the inner ring of the bearing, the rotating ring and the connecting ring can be easily connected, reducing the losses generated during rotation.
[0014] In one specific implementation, a sealing ring is fixedly connected to one side of the connecting ring, and the sealing ring is in contact with the body of the rubber replacement valve.
[0015] In the above process, the sealing ring fits into the body of the glue-changing valve, which facilitates sealing and prevents glue leakage.
[0016] In one specific implementation, a piston is fixedly connected to one end of the push column, and the piston is in contact with the inner wall of the dispensing tube.
[0017] In the above process, by having the piston fit against the inner wall of the dispensing tube, the cleaning effect can be easily improved.
[0018] Compared with the prior art, the beneficial effects of this application are as follows: by setting up the glue inlet component, it is convenient to supply glue to the glue replacement valve body. By pulling the component to drive the push column to move, it is convenient to push out the residual glue in the glue outlet tube after the glue replacement valve body is used, so as to avoid the glue solidifying on the inner wall of the glue outlet tube and causing blockage of the glue outlet tube.

Detailed Implementation
[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0026] Please see Figure 1 This application provides an anti-clogging glue replacement valve, including a glue inlet structure 10 and a cleaning structure 20.
[0027] Please see Figure 1 and Figure 2 The glue injection structure 10 includes two support plates 110 and a glue injection assembly 120, wherein the glue injection assembly 120 is disposed within the support plates 110.
[0028] In a specific configuration, the glue feeding assembly 120 includes a storage cylinder 121 and a glue feeding pipe 122. The storage cylinder 121 is fixedly connected to the support plate 110. The two ends of the glue feeding pipe 122 are respectively connected to the storage cylinder 121 and the glue changing valve body 210. The storage cylinder 121 and the glue feeding pipe 122 facilitate glue supply to the glue changing valve body 210.
[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The cleaning structure 20 includes a glue-changing valve body 210, a glue outlet pipe 220, a pulling assembly 230, and a pushing column 240. Two support plates 110 are arranged parallel to each other on one side of the glue-changing valve body 210. The glue inlet assembly 120 is connected to the glue-changing valve body 210, the glue outlet pipe 220 is connected to the glue-changing valve body 210, the pulling assembly 230 is slidably connected to the glue-changing valve body 210, the pushing column 240 is connected to the pulling assembly 230, and the pushing column 240 is in contact with the inner wall of the glue outlet pipe 220.
[0030] In a specific configuration, the pulling assembly 230 includes a pull ring 231, a rotating ring 232, a connecting ring 233, and two L-shaped pull plates 234. The rotating ring 232 is fixedly connected to the pull ring 231, and the rotating ring 232 is rotatably connected to the connecting ring 233. Two L-shaped pull plates 234 are fixedly connected to one side of the connecting ring 233. Both L-shaped pull plates 234 are fixedly connected to the push column 240, and both L-shaped pull plates 234 are slidably connected to the rubber changing valve body 210. The arrangement of the pull ring 231, rotating ring 232, connecting ring 233, and two L-shaped pull plates 234 facilitates the pulling of the push column 240.
[0031] In a specific configuration, an mounting ring 250 is fixedly connected to one side of the glue-changing valve body 210, and the rotating ring 232 is threadedly connected to the mounting ring 250. The threaded connection between the rotating ring 232 and the mounting ring 250 facilitates the fixed connection between the rotating ring 232 and the glue-changing valve body 210, preventing the glue outlet pipe 220 from being blocked when the glue-changing valve body 210 is in use due to the glue squeezing pushing the column 240.
[0032] In a specific configuration, the connecting ring 233 is fitted with a bearing, and the rotating ring 232 is interference-fitted with the inner ring of the bearing. The interference fit between the rotating ring 232 and the inner ring of the bearing facilitates the rotational connection between the rotating ring 232 and the connecting ring 233, reducing the losses generated during rotation.
[0033] In a specific configuration, a sealing ring 260 is fixedly connected to one side of the connecting ring 233. The sealing ring 260 is in contact with the glue replacement valve body 210. The contact between the sealing ring 260 and the glue replacement valve body 210 facilitates sealing and prevents glue leakage.
[0034] In a specific configuration, a piston 270 is fixedly connected to one end of the push column 240. The piston 270 is in contact with the inner wall of the dispensing tube 220. The contact between the piston 270 and the inner wall of the dispensing tube 220 can improve the cleaning effect.
[0035] The working principle of this anti-clogging glue replacement valve is as follows: When using the anti-clogging glue replacement valve, glue is transported from the storage cylinder 121 to the glue replacement valve body 210 through the glue inlet pipe 122, and then discharged through the glue outlet pipe 220. When the glue replacement valve body 210 is finished, the pull ring 231 is manually rotated to cause the rotating ring 232 to disengage from the threaded fixing of the mounting ring 250. Then, the pull ring 231 is pulled axially. The friction is reduced by the cooperation between the connecting ring 233 and the bearing, which drives the L-shaped pull plate 234 to push... The moving column 240 and piston 270 move within the dispensing tube 220, squeezing out residual glue from the dispensing tube 220 to prevent the glue from solidifying on the inner wall of the dispensing tube 220 and causing blockage. The moving column 240 and piston 270 are retained within the dispensing tube 220. When the glue replacement valve body 210 is used next time, the reverse operation pulls the assembly 230 to reset the moving column 240 and fix the rotating ring 232. The sealing ring 260 prevents glue leakage.
[0036] It should be noted that the specific model and specifications of the rubber replacement valve body 210 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0037] The power supply and principle of the rubber replacement valve body 210 are clear to those skilled in the art and will not be described in detail here.
[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
