Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, and in particular to a split-type two-component plunger valve. Background Technology

[0002] Adhesive processing is the process of producing adhesive products with specific bonding properties by mixing, reacting, and modulating basic raw materials. Its core is to control the viscosity, curing speed, bonding strength, and temperature resistance of the adhesive according to the needs of the application scenario. Solvent-based adhesives are gradually being replaced by water-based and solvent-free adhesives. Therefore, adhesive processing is a systematic project involving formulation development, process control, and quality inspection. It is necessary to optimize the raw material ratio and process parameters according to the specific application scenario, while taking into account safety and environmental protection requirements.

[0003] The main task in glue processing is to mix different types of raw materials for production. This process requires guiding the mixing of raw materials. In existing technologies, plunger valves used to guide the raw materials mostly use an integral diaphragm to detect air pressure and then drive the operation of other structures. However, the integral structure means that both sides of the plunger valve need to be disassembled for maintenance, which reduces practicality and maintenance efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a split-type two-component plunger valve, which aims to improve the problem that existing plunger valves mostly use an integral diaphragm, requiring both sides of the plunger valve to be disassembled for maintenance during replacement and maintenance, resulting in reduced practicality and maintenance efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a split-type two-component plunger valve, including a frame, a plurality of hollow tubes fixedly connected to the top of the inner wall of the frame, a valve body connected to the top of the inner wall of the hollow tubes, a feed pipe connected to the inner wall of the hollow tubes, a sliding plug slidably connected to the rear side of the inner wall of the hollow tubes, a spring provided on the outer wall of the sliding plug, a pneumatic diaphragm provided on the rear side of the hollow tubes, a positioning block provided on the rear side of the pneumatic diaphragm, a material diaphragm provided on the rear side of the positioning block, a positioning plate provided on the rear side of the material diaphragm, a locking block slidably connected to the inner wall of the valve body, a sliding rod slidably connected to the inner wall of the locking block, and a plurality of screws threadedly connected to the inner wall of the positioning plate.

[0006] As a further description of the above technical solution:

[0007] An observation window is fixedly connected to the rear side of the valve body.

[0008] As a further description of the above technical solution:

[0009] Each of the four corners at the top of the valve body is threaded with two screws.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the feed pipe is provided with a clamp.

[0012] As a further description of the above technical solution:

[0013] The bottom of the frame is connected to a connecting pipe, and the inner wall of the connecting pipe is provided with multiple discharge slots.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the clamp is rotatably connected to a rotating shaft.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the clamp plate is threaded with bolts near the edge.

[0018] As a further description of the above technical solution:

[0019] A piston is engaged with the top rear side of the valve body.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, adhesives with different components are guided into the hollow tube from the feed pipe, causing it to push the sliding rod upward. Subsequently, the remaining structures impact the sliding rod, thereby pushing the adhesive to squeeze the sliding plug and compress the spring. The pneumatic diaphragm provides a pressure signal to drive the remaining structures to process, so that the mixed adhesive flows out through the discharge trough. At the same time, the pneumatic diaphragm is a split type, which not only guides the mixing of adhesives but also makes it convenient for users to disassemble and maintain, improving maintenance efficiency and practicality.

[0029] 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.

[0030] Please see the appendix Figure 3 Appendix Figure 4 and attached Figure 5 An embodiment of this utility model provides a split-type two-component plunger valve, including a frame 1. Multiple hollow tubes 4 are fixedly connected to the top of the inner wall of the frame 1. A valve body 6 is connected to the top of the inner wall of the hollow tubes 4. A feed pipe 2 is connected to the inner wall of the hollow tubes 4. A sliding plug 11 is slidably connected to the rear side of the inner wall of the hollow tubes 4. A spring 12 is provided on the outer wall of the sliding plug 11. A pneumatic diaphragm 10 is provided on the rear side of the hollow tubes 4. A positioning block 9 is provided on the rear side of the pneumatic diaphragm 10. A material diaphragm 8 is provided on the rear side of the positioning block 9. A positioning plate 7 is provided on the rear side of the material diaphragm 8. A locking block 13 is slidably connected to the inner wall of the valve body 6. A sliding rod 14 is slidably connected to the inner wall of the locking block 13. Multiple screws 3 are threadedly connected to the inner wall of the positioning plate 7.

[0031] Specifically, the pneumatic diaphragm 10 is the power transmission component of the plunger valve. It deforms by receiving the pressure of external compressed air. The positioning block 9 fixes the position of the pneumatic diaphragm 10 to prevent displacement and shaking during operation, ensuring that the pneumatic diaphragm 10 can accurately transmit pressure. The material diaphragm 8 is mainly used to protect the positioning block 9 and the pneumatic diaphragm 10, preventing corrosion and damage from the two-component adhesive material. The positioning plate 7 provides stable support and positioning for the entire pneumatic diaphragm 10, ensuring that the relative positions between the components are accurate. The locking block 13 provides guidance and support for the movement of the sliding rod 14, ensuring that the sliding rod 14 can slide along a predetermined trajectory.

[0032] Please see the appendix Figure 1 and attached Figure 2 An observation window 20 is fixedly connected to the rear side of the valve body 6, and a clamping plate 18 is provided on the outer wall of the feed pipe 2. A bolt 19 is threadedly connected to the inner wall of the clamping plate 18 near the edge.

[0033] Specifically, the observation window 20 helps the user observe the lubricating oil inside the valve body 6, thereby helping the user determine whether the lubricating oil needs to be replaced, and the clamp 18 is used to connect the glue injection tube and the feed tube 2.

[0034] Please see the appendix Figure 2 and attached Figure 3 Screws 21 are threaded at the four corners of the top of the valve body 6, and a rotating shaft 17 is rotatably connected to the inner wall of the clamping plate 18.

[0035] Specifically, screw 21 is used to position and install valve body 6. Rotating shaft 17 supports the clamping plate 18 to rotate and open.

[0036] Please see the appendix Figure 2 and attached Figure 3 The bottom of the frame 1 is connected to a connecting pipe 15, and the inner wall of the connecting pipe 15 is provided with multiple discharge slots 16. The top rear side of the valve body 6 is engaged with a piston 5.

[0037] Specifically, the connecting pipe 15 is used to guide the glue to flow downward from the hollow tube 4 and to discharge downward through the discharge trough 16. The piston 5 can open the valve body 6 to replace the lubricating oil inside.

[0038] Working principle: First, observe the lubricating oil in the valve body 6 through the observation window 20 to confirm whether its color meets the standard, thereby determining whether replacement is necessary. Then, through the feed pipes 2 on both sides, different components of glue enter the hollow tube 4, gradually pushing the sliding rod 14 upward from inside. At the same time, due to the elastic force of the spring 12, the sliding plug 11 is squeezed outward by the glue, which in turn pushes the air in the positioning block 9. The air pressure signal is transmitted through the material diaphragm 8 and the pneumatic diaphragm 10, which in turn provides a signal to the other processing mechanisms to impact the sliding rod 14, causing it to push the glue to squeeze the sliding plug 11 outward. This allows the mixed glue to enter the connecting pipe 15 and be discharged outward from the discharge trough 16. Meanwhile, the material diaphragm 8 and the pneumatic diaphragm 10 are separate units located on the left and right sides of the entire structure. If one of them is damaged, there is no need to disassemble the whole structure.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
