Description

Technical Field

[0001] This utility model relates to the field of glue supply switch technology for coating machines, and more specifically, to a glue supply switch device for a thermoplastic warm edge spacer coating machine. Background Technology

[0002] A coating machine is an industrial piece of equipment typically used to apply liquids such as adhesives and coatings to the surface of paper or fabric. By controlling the amount and speed of coating, different production needs can be met. It is commonly used in industries such as packaging, electronics, and printing. The adhesive supply switch device of the coating machine is a component that controls the delivery of adhesive. It is used to control the supply and cut-off of adhesive to the coating mechanism, allowing users to make appropriate controls in different situations.

[0003] The glue supply switch device of a coating machine is generally composed of a glue inlet channel, a valve core, and a drive assembly. The drive assembly drives the valve core to realize the delivery and shut-off of the glue, and is a component that maintains the stable operation of the coating machine.

[0004] In existing technologies, the glue supply switch device of some coating machines is prone to jamming or switch failure due to the pressure inside the cavity during glue replenishment. This can lead to glue supply interruption, disrupt the coating rhythm, and cause defects such as missed coating or glue breakage on the substrate surface, reducing the product qualification rate. At the same time, jammed plug-in structures require machine shutdown for disassembly and maintenance, which reduces production time and affects capacity. Therefore, it is impossible to avoid the occurrence of plug-in structure jamming. To solve the above problems, a glue supply switch device for a thermoplastic warm edge spacer coating machine is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a glue supply switch device for a thermoplastic warm edge spacer coating machine, so as to solve the problem that the plug-in structure cannot be prevented from jamming in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a glue supply switch device for a thermoplastic warm edge spacer coating machine, comprising...

[0007] The glue inlet block is connected to two rotary cylinders. One of the rotary cylinders is fixedly connected to a switch valve core, and the other rotary cylinder is fixedly connected to a switch valve core. The inner wall of the glue inlet block is detachably connected to a connector. The inner wall of the connector is fixedly connected to two S-shaped elastic elements, and the inner wall of the connector is slidably connected to two inclined locking blocks.

[0008] Each of the two S-shaped elastic elements has a pressure plate fixedly connected to one end away from the connector, a connecting block fixedly connected to one end of the pressure plate, and a washer fixedly connected to the outside of the connector.

[0009] A filter element is fixedly connected to the inner wall of the connector, a through hole is formed in the inner wall of the connector, a sliding groove is formed in the inner wall of the connector, and the outer side of the pressure plate is slidably connected to the inner wall of the sliding groove.

[0010] The external rotatable connection of the first switch valve core is to the inner wall of the glue inlet block, and the external rotatable connection of the second switch valve core is to the inner wall of the glue inlet block.

[0011] The pressure plate is slidably connected to the inner wall of the connector, and the end of the pressure plate away from the connector is fixedly connected to the outside of the inclined card block.

[0012] The filter element is fixedly connected to the inner wall of the through hole, and the connecting block is slidably connected to the inner wall of the connector.

[0013] The oblique locking block is engaged with the inner wall of the glue inlet block at one end away from the connector, and the gasket is in contact with the outside of the glue inlet block at one end away from the connector.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, the rotation of switch valve core one and switch valve core two by a rotary cylinder can realize the operation of replenishing and discharging material into the glue inlet block. The rotary cylinder can achieve continuous and stable glue discharging by alternating glue replenishment of switch valve core one and switch valve core two. The glue replenishment switch action is realized by rotating switch valve core one or switch valve core two with a rotary cylinder. Switch valve core one and switch valve core two move flexibly and are not prone to jamming. At the same time, when the glue is fed into the glue inlet block, the glue will first pass through the connector to filter out the impurities contained in the glue, so as to prevent impurities from entering the glue inlet block and affecting its components. Furthermore, the connector adopts a modular quick-release design, which provides convenience for subsequent maintenance. Attached Figure Description

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a glue supply switch device for a thermoplastic warm edge spacer coating machine, including a glue inlet block 1 and two rotary cylinders 2. One rotary cylinder 2 has a switch valve core 3 fixedly connected to its driving end, and the other rotary cylinder 2 has a switch valve core 4 fixedly connected to its driving end. A connector 5 is detachably connected to the inner wall of the glue inlet block 1. Two S-shaped elastic elements 6 are fixedly connected to the inner wall of the connector 5. Two inclined blocks 8 are slidably connected to the inner wall of the connector 5. The outer side of the switch valve core 3 is rotatably connected to the inner wall of the glue inlet block 1, and the outer side of the switch valve core 4 is rotatably connected to the inner wall of the glue inlet block 1.

[0025] The alternating activation of two rotary cylinders 2 enables the internal replacement of adhesive, thus achieving stable adhesive dispensing and preventing jamming. The cooperation of the S-shaped elastic element 6 and the inclined locking block 8 enables quick disassembly and assembly of the connector 5, facilitating subsequent maintenance. Furthermore, the connector 5 can filter impurities in the adhesive, preventing them from entering the interior of the adhesive inlet block 1 and causing damage to its internal components.

[0026] Example 2: Based on Example 1, in order to facilitate the movement of the inclined locking block 8, pressure plates 7 are fixedly connected to the ends of the two S-shaped elastic elements 6 away from the connector 5. A connecting block 9 is fixedly connected to one end of the pressure plate 7. A washer 10 is fixedly connected to the outside of the connector 5. The outside of the pressure plate 7 is slidably connected to the inner wall of the connector 5. The end of the pressure plate 7 away from the connecting block 9 is fixedly connected to the outside of the inclined locking block 8. The end of the inclined locking block 8 away from the connector 5 is engaged with the inner wall of the glue inlet block 1. The end of the washer 10 away from the connector 5 is in contact with the outside of the glue inlet block 1.

[0027] When connecting the connector 5 to the glue inlet in the glue inlet block 1, pressing the two connecting blocks 9 in the connector 5 allows the connecting blocks 9 to transmit force to the S-shaped elastic element 6 through the pressure plate 7. The S-shaped elastic element 6 contracts when deformed, satisfying the space required for the inclined locking block 8 to be hidden in the connector 5. At this time, the connector 5 can be inserted into the glue inlet block 1. Then, the connecting blocks 9 are released, allowing the inclined locking block 8 to be locked inside the glue inlet block 1 for connection. At this time, the gasket ring 10 in the connector 5 will squeeze the glue inlet block 1 to form a sealing effect, preventing leakage during glue delivery.

[0028] Example 3: Based on Example 2, in order to facilitate the filtration of the adhesive, a filter sheet 11 is fixedly connected to the inner wall of the connector 5, a through hole 12 is opened in the inner wall of the connector 5, a sliding groove 13 is opened in the inner wall of the connector 5, the outer side of the pressure plate 7 is slidably connected to the inner wall of the sliding groove 13, the outer side of the filter sheet 11 is fixedly connected to the inner wall of the through hole 12, and the outer side of the connecting block 9 is slidably connected to the inner wall of the connector 5.

[0029] Meanwhile, during the conveying of adhesive, impurities such as metal shavings and dust may be mixed in with the adhesive during production or conveying. If these impurities enter the flow channel of the adhesive replenishment switch device, they can easily get stuck in the mating gap between the adhesive inlet block 1 and the first and second valve cores 3 and 4, causing the valve cores to rotate inflexibly or even jam, affecting the normal operation of the adhesive replenishment switch. Therefore, when the adhesive passes through the filter 11 in the connector 5, these impurities will be filtered by the filter 11 to prevent them from flowing into the interior of the adhesive inlet block 1 and causing blockage and jamming. When it is necessary to clean and maintain the connector 5, the connector 5 can be pulled out for cleaning by pressing the connector block 9, which not only satisfies the need for filtering the adhesive but also provides convenience for subsequent maintenance.

[0030] The working process of this utility model is as follows:

[0031] Firstly, when a glue replenishment operation is required, one of the rotary cylinders 2 is activated, causing the switch valve core 3 to rotate and connect the internal channels, making the internal channels interconnected. This allows for glue replenishment. The alternating glue replenishment by the two rotary cylinders 2 ensures continuous and stable glue dispensing, reducing the risk of jamming. Simultaneously, when the connector 5 is connected to the glue inlet in the glue block 1, pressing the two connecting blocks 9 in the connector 5 allows the connecting blocks 9 to transmit force to the S-shaped... In the elastic element 6, the S-shaped elastic element 6 contracts when deformed, satisfying the space required for the inclined locking block 8 to be hidden in the connector 5. At this time, the connector 5 can be inserted into the glue block 1. Then, the connector block 9 is released so that the inclined locking block 8 is locked inside the glue block 1 for connection. At this time, the gasket ring 10 in the connector 5 will squeeze the glue block 1 to form a sealing effect, preventing leakage during glue conveying. At the same time, during glue conveying, due to the glue material being mixed with impurities such as metal shavings and dust during production or conveying, impurities may be mixed in. If these impurities enter the flow channel of the glue filling switch device, they can easily get stuck in the gap between the glue inlet block 1 and the first and second switch valve cores 3 and 4, causing the valve cores to rotate inflexibly or even jam, affecting the normal operation of the glue filling switch. Therefore, when the glue passes through the filter 11 in the connector 5, these impurities will be filtered by the filter 11 to prevent them from flowing into the interior of the glue inlet block 1 and causing blockage and jamming. When it is necessary to clean and maintain the connector 5, the connector 5 can be pulled out for cleaning by pressing the connector block 9, which satisfies the filtering of the glue and provides convenience for subsequent maintenance.
