Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of glue supply pump, especially a glue supply double ball pump. BACKGROUND

[0002] In the field of glue delivery, the traditional glue supply double ball pump often faces many challenges when delivering high-viscosity glue. Due to the poor flowability of high-viscosity glue and the generation of large pressure and friction during flow, the sealing performance and wear resistance of the glue supply double ball pump are highly required. However, the existing glue supply double ball pump has obvious deficiencies in sealing design and self-lubrication function.

[0003] Specifically, the sealing element of the traditional glue supply double ball pump often cannot withstand the huge pressure generated by high-viscosity glue during flow, which easily leads to leakage, resulting in waste of glue and pollution of the working environment. At the same time, the large friction generated by high-viscosity glue during flow in the pump body easily accelerates the wear of the pump body and shortens the service life of the pump body. In addition, the traditional glue supply double ball pump often has the problem of air mixing during the process of sucking and discharging glue, which affects the normal delivery of glue and reduces work efficiency.

[0004] In addition, the lubrication method of the traditional glue supply double ball pump usually relies on external lubrication, which not only increases the complexity and cost of maintenance, but also makes it difficult to ensure the durability and stability of the lubrication effect. Especially when delivering high-viscosity glue, external lubrication is difficult to effectively penetrate into all contact surfaces of the pump body, which easily leads to dry grinding and overheating of the pump body during work.

[0005] Therefore, there is an urgent need for a glue supply double ball pump with excellent sealing performance, self-lubrication function, and high work efficiency to solve the technical problems of leakage, wear, air mixing, and insufficient lubrication of the traditional glue supply double ball pump when delivering high-viscosity glue. This new type of glue supply double ball pump should be able to adapt to the delivery needs of various types of glue, improve work efficiency, prolong service life, and simplify maintenance procedures to meet the high performance requirements of modern industrial production for the glue supply double ball pump.

[0006] Therefore, we propose a glue supply double ball pump. Utility model content

Through its excellent sealing performance, innovative self-lubrication function, and high work efficiency and wide applicability, the overall performance of the pump body is significantly improved. Specifically, the combination of multi-layer sealing design and self-lubrication function effectively solves the problems of leakage, wear, and insufficient lubrication of the traditional glue supply pump when delivering high-viscosity glue.

[0037] The specific embodiments of the utility model will be described below in conjunction with the drawings.

[0038] The utility model relates to a kind of glue supply double-ball pump technical field, specifically a kind of glue supply double-ball pump, its structure design is novel, can effectively improve the sealing performance of pump body, while having self-lubricating function, extend the service life of pump body, the technical scheme in the embodiment of the utility model will be described clearly and completely in conjunction with the drawings in the embodiment of the utility model, obviously, the described embodiment is only a part of the embodiment of the utility model, not all embodiments.

[0039] Referring to Figures 1 to 3 As shown in the utility model discloses a kind of glue supply double-ball pump, comprising:

[0040] The piston head 202 is slidably disposed inside the cylinder 200. The piston head 202 is connected to the drive structure 400 and moves up and down to realize the intake and discharge of glue.

[0041] The feeding section 100 is equipped with a lower ball 101. The lower ball 101 moves freely within a certain range in response to the pressure generated by the piston moving up and down, and intermittently controls the flow of materials.

[0042] The piston head 202 is provided with an upper ball 201. The upper ball 201 moves freely within a certain range in response to the pressure generated by the piston moving up and down, intermittently controlling the flow of materials. The upper ball 201 moves in the opposite direction to the lower ball 101.

[0043] The other end of the discharge section 300 is connected to a filling shell 500. The upper end of the filling shell 500 is open, and a second sealing element 303 is provided between the filling shell 500 and the discharge section 300.

[0044] like Figure 1 As shown, the feed section 100 in this embodiment serves as the entrance for the adhesive, and its design facilitates the smooth entry of the adhesive.

[0045] The feeding section 100 is equipped with a lower ball 101, which can move freely within a certain range to respond to the negative pressure generated by the piston head 202.

[0046] A first movable cavity 102 is provided below the lower ball 101, which provides space for the lower ball 101 to move.

[0047] The first movable chamber 102 has a first liquid hole 103 on its side wall, which allows the glue to flow between the first movable chamber 102 and the space above the piston head 202.

[0048] A lower ball stop pin 104 is provided above the lower ball 101 to limit the upward movement distance of the lower ball 101 and ensure that it can seal the feed port of the first active cavity 102 when it is in a specific position.

[0049] In this embodiment, the cylinder 200 is the main part of the pump body, and its inner wall is smooth to reduce the resistance when the glue flows.

[0050] Specifically, a piston head 202 is provided inside the cylinder 200. The piston head 202 can move up and down inside the cylinder 200 to realize the intake and discharge of glue.

[0051] An upper ball 201 is provided above the piston head 202, and the upper ball 201 can move freely in the second movable cavity inside the piston head 202.

[0052] A top ball stop pin 203 is provided above the top ball 201 to limit the upward movement distance of the top ball 201.

[0053] The piston head 202 is provided with an upper ball 201, which is capable of freely moving in the second movable cavity in the piston head and is positioned under the restriction of an upper ball blocking pin 203. This design helps to seal the lower port of the second movable cavity when the piston head moves upward, preventing the glue from leaking upward.

[0054] The feeding section 100 is provided with a lower ball 101, which is capable of freely moving within a certain range to respond to the negative pressure generated by the piston head. The lower ball is capable of blocking the feeding port of the first movable cavity 102 under the dual action of pressure and gravity, preventing the glue from leaking downward. This design can ensure the stable flow of glue in the pump body for high-viscosity glue, avoiding leakage and backflow.

[0055] The piston head 202 is provided with a second liquid hole 204 on the side wall, allowing the glue to flow between the space above the piston head 202 and the discharge section 300.

[0056] The piston head 202 is provided with a first sealing member 205, which is tightly fitted with the inner wall of the cylinder 200, improving the sealing performance of the pump body.

[0057] The piston head 202 is provided with a first sealing member 205, which is tightly fitted with the inner wall of the cylinder 200. This design can effectively prevent the glue from leaking under high pressure, which is particularly important for high-viscosity glue, as high-viscosity glue generates greater pressure when flowing, requiring higher sealing performance.

[0058] As shown in Figure 1 and Figure 2 , the discharge section 300 in this embodiment serves as the outlet part of the glue, which helps to smoothly discharge the glue.

[0059] The discharge section 300 is provided with an exhaust hole 301 on the side wall, which is provided with a one-way valve (not shown in the figure) for discharging air in the pump, preventing air from affecting the normal transportation of the glue.

[0060] The discharge section 300 is provided with at least one discharge port 302, the height of which is lower than that of the exhaust hole 301, ensuring that the glue will not be affected by air when discharged.

[0061] The discharge section 300 is provided with at least one discharge port 302, the height of which is lower than that of the exhaust hole 301, ensuring that the glue will not be affected by air when discharged.

[0062] The filling shell 500 is inserted into the opening of the discharge section 300 on the side of the driving mechanism 400, and a certain amount of lubricating oil can be filled in the filling shell to lubricate the contact surface between the piston rod 600 and the discharge section 300. The self-lubricating function is very important for reducing the wear of the pump body during operation, especially for high-viscosity glue, because the friction generated by high-viscosity glue when flowing is larger, which can easily accelerate the wear of the pump body, and because the pressure in the cylinder barrel 200 is very large, the lubricating oil can also avoid entering the cylinder barrel through the second sealing element 303, and the presence of leakage at the second sealing element 303 can also be determined through the lubricating oil, and the sealing effect is further improved, which is convenient for conveying high-viscosity glue.

[0063] The second sealing element 303 is arranged between the filling shell 500 and the discharge section 300, and the second sealing element 303 is tightly attached to the piston rod 600, thereby improving the sealing performance of the pump body.

[0064] The second sealing element 303 is arranged on the inner wall of the discharge section 300, and the second sealing element 303 is arranged on the inner wall of the discharge section 300.

[0065] The driving mechanism 400 in the embodiment is connected with the discharge section 300 through a driving rod 401, and the driving rod 401 can move up and down to drive the piston rod 600 and the piston head 202 to move together.

[0066] The driving mechanism 400 can be electrically driven, pneumatically driven or hydraulically driven, and the specific selection is determined according to actual use requirements.

[0067] As shown in the drawings, Figure 3 The piston rod 600 in the embodiment is connected with the piston head 202 and the driving rod 401, and transmits the power of the driving mechanism 400 to make the piston head 202 move up and down in the cylinder barrel 200.

[0068] The working principle of the utility model is as follows:

[0069] Suction process:

[0070] When the driving mechanism 400 drives the driving rod 401 to move upwards, the piston rod 600 and the piston head 202 also move upwards.

[0071] At this time, the upper ball 201 in the piston head 202 is limited in the second movable cavity and seals the lower port of the second movable cavity to prevent the glue from leaking upwards.

[0072] With the upward movement of the piston head 202, a negative pressure is generated in the region between the piston head 202 and the feeding section 100.

[0073] Under the action of the negative pressure, the lower ball 101 moves upwards and is positioned by the lower ball stop pin 104.

[0074] The glue flows through the gap between the first movable cavity 102 and the lower ball 101 and the first liquid hole 103 to the area between the piston head 202 and the feeding section 100, realizing the suction of the glue.

[0075] Discharge process:

[0076] When the piston head 202 moves to the highest position, the driving mechanism 400 drives the driving rod 401 to move downward, and the piston rod 600 and the piston head 202 also move downward.

[0077] At this time, the lower ball 101 blocks the feeding port of the first movable cavity 102 under the action of pressure and gravity, preventing the glue from leaking downward.

[0078] At the same time, the upper ball 201 moves upward under the action of the glue and is positioned by the upper ball blocking pin 203.

[0079] The glue moves upward along the gap between the second movable cavity and the upper ball 201 and passes through the second liquid hole 204 into the space above the piston head 202.

[0080] With the downward movement of the piston head 202, the glue is compressed and delivered outward through the discharge port 302.

[0081] Self-lubricating function:

[0082] During the operation of the pump body, the lubricating oil in the filling shell 500 penetrates into the contact surface through the gap between the piston rod 600 and the discharge section 300, realizing the self-lubricating function.

[0083] The design of the second sealing member 303 ensures that the lubricating oil does not leak into the pump body, and at the same time does not affect the normal movement of the piston rod 600.

[0084] The double-ball pump for glue provided by the utility model has the following beneficial effects compared with the prior art:

[0085] In this embodiment, by sleeving the first sealing member 205 on the piston head 202 and arranging the second sealing member 303 between the filling shell 500 and the discharge section 300, the sealing performance of the pump body is effectively improved.

[0086] The first sealing member 205 and the second sealing member 303 are both V-shaped sealing rings arranged in multiple layers, which have good sealing effect and wear resistance. Such sealing rings have good sealing effect and wear resistance and can withstand the friction and pressure generated by the high-viscosity glue when flowing. At the same time, the first sealing member 205 and the second sealing member 303 have openings facing upward, that is, their sharp ends face downward, which can overcome the hydraulic pressure of the glue at the lower end.

[0087] The circumferential direction of the piston head is also provided with an annular groove for fixing the first sealing member 205, thereby improving the connection effect of the first sealing member 205.

[0088] Meanwhile, in the embodiment, the filling shell 500 is inserted into the side wall of the discharge section 300, and the lubricating oil is injected into the filling shell 500, so that the self-lubricating function of the pump body is realized.

[0089] The self-lubricating function reduces the wear of the pump body during operation, and prolongs the service life of the pump body.

[0090] Improve work efficiency:

[0091] The novel structure design of the glue supply double-ball pump is simple and reliable in working principle, and can efficiently suck and discharge glue.

[0092] Through the design of the exhaust hole 301 and the one-way valve, the air in the pump is effectively discharged, and the influence of air on glue delivery is prevented.

[0093] The novel structure design of the glue supply double-ball pump is simple and reliable in working principle, and can efficiently suck and discharge glue.

[0094] By adjusting the structure and parameters of the pump body, the needs in different use scenarios can be met.

[0095] The self-lubricating function in the embodiment reduces the dependence of the pump body on external lubrication, and simplifies the maintenance process.

[0096] The structure design of the pump body is reasonable, easy to disassemble and clean, and convenient for users to carry out daily maintenance and maintenance.

[0097] In summary, the novel structure design of the glue supply double-ball pump is simple and reliable in working principle, has good sealing performance, has a self-lubricating function, is high in working efficiency, is strong in applicability, and is easy to maintain.

[0098] In addition, the novel structure design of the glue supply double-ball pump is simple and reliable in working principle, has good sealing performance, has a self-lubricating function, is high in working efficiency, is strong in applicability, and is easy to maintain.
