Description

Technical Field

[0001] This utility model relates to the field of automated glue spraying equipment technology, and in particular to a glue wiping device for a dual-spray valve. Background Technology

[0002] Glue spray valves are widely used, especially for products with irregular shapes and high precision requirements for glue application. In automated glue spraying equipment, due to the valve's structure and the high-precision requirements of its application, the nozzle needs frequent cleaning of residual glue; otherwise, the glue spraying process and the size of the glue dots will be affected.

[0003] The main purpose of "wiping" the glue spray valve is to address glue residue issues, maintain stable operation, and ensure spray accuracy. The primary objectives are: 1) to remove residual glue from the nozzle after each spray, preventing accumulation and drying that could clog the nozzle; 2) to ensure accurate glue volume, precise positioning, and consistent shape with each spray; 3) to eliminate potential glue stringing issues; 4) to reduce contamination of the sealing surface and prevent valve leakage; and 5) to maintain critical components and extend the valve's lifespan. In short, wiping the glue spray valve is a necessary and routine maintenance procedure for ensuring efficient, stable, and accurate operation.

[0004] Existing technologies, such as the adhesive wiping device disclosed in CN222551180U, are only suitable for dispensing machines with a single adhesive spray valve, and not for dispensing machines with two dispensing valves. If this wiping device is used on a dispensing machine with two dispensing valves, adhesive wiping is required twice, wiping each valve separately. Since adhesive needs to be sprayed onto the receiving box and then wiped before each dispensing, this increases the cleaning frequency and reduces cleaning efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by designing a glue-wiping device for a dual-spray valve, which solves the problem that existing glue-wiping devices cannot meet the glue-wiping requirements of dual-spray valves.

[0006] The technical solution of this utility model to achieve the above objectives is a glue-wiping device for dual-dispensing valves, used for glue-wiping operations on two dispensing valves, comprising:

[0007] device body;

[0008] The driving wheel and the driven wheel are rotatably connected to the same side of the device body and are used to wind up and unwind the cleaning cloth, respectively.

[0009] Two cleaning tanks are located between the driving wheel and the driven wheel, and are used to add cleaning agent to the two cleaning sponges respectively. The distance between the two cleaning tanks is adapted to the distance between the two dispensing valves.

[0010] The first auxiliary shaft, the tensioning shaft, and the second auxiliary shaft are rotatably connected to the side of the device body where the driving wheel and the driven wheel are located, and are close to the driven wheel, wherein the tensioning shaft is located below the first auxiliary shaft and the second auxiliary shaft;

[0011] The third auxiliary shaft is rotatably connected to the side of the device body where the driving wheel and the driven wheel are located, and is close to the driving wheel;

[0012] After being released from the drive wheel, the cleaning cloth passes sequentially through the first auxiliary shaft, the tensioning shaft, and the second auxiliary shaft, and is moistened after passing over the upper surface of the cleaning sponge. Then, it passes through the third auxiliary shaft and is rolled up onto the drive wheel.

[0013] Preferably, a drive motor is installed inside the device body, and the output shaft of the drive motor is driven and connected to the drive wheel.

[0014] Preferably, the device body is provided with a drive shaft and a driven shaft, the drive wheel is mounted on the drive shaft, the driven wheel is mounted on the driven shaft, and the output shaft of the drive motor is connected to the drive shaft for transmission.

[0015] Preferably, the device body is provided with two glue collection cups, which are used to collect excess glue from the two glue spray valves respectively. The mouth of the glue collection cup protrudes from the upper surface of the device body, and the distance between the two glue collection cups is adapted to the distance between the two glue spray valves.

[0016] Preferably, a cross-shaped baffle is provided at one end of the tensioning shaft located inside the device body, and a photoelectric sensor that cooperates with the cross-shaped baffle is provided inside the device body. The photoelectric sensor is linked to the control system of the drive motor.

[0017] Preferably, the bottom of the device body is provided with a base plate, and the base plate has a tool slot for placing tools.

[0018] Preferably, one side of the device body is provided with an electrical control cable connector for connecting to the electronic components inside the device body.

[0019] Its advantages over existing technologies are:

[0020] This invention's adhesive-wiping device can simultaneously wipe adhesive from two adhesive spray valves. After being released from the driven wheel, the cleaning cloth passes sequentially through the first auxiliary shaft, the tensioning shaft, and the second auxiliary shaft, and is moistened after passing over the upper surface of the cleaning sponge. It then passes through the third auxiliary shaft and is wound onto the driving wheel. Under the action of the tensioning shaft, the cleaning cloth remains taut and adheres tightly to the cleaning sponge in the cleaning tank. This allows the cleaning cloth to rub against the valve heads of the adhesive spray valves during wiping, enabling the valve heads of both spray valves to be cleaned simultaneously, reducing the frequency of wiping and improving cleaning efficiency.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figure 1 As shown, a preferred embodiment of this utility model provides a glue-wiping device for dual-spray valves, which can simultaneously perform glue-wiping operations on two dispensing valves on a dispensing machine.

[0027] Specifically, the adhesive wiping device mainly consists of a base plate 12, a device body 1, a drive wheel 2, a driven wheel 3, two cleaning tanks 8, and multiple auxiliary shafts.

[0028] The device body 1 is fixedly mounted on the base plate 12, which is generally mounted on the machine base of the dispensing machine.

[0029] A driven shaft and a driving shaft (not shown in the figure) are respectively provided on the left and right sides of the front of the device body 1. Both the driven shaft and the driving shaft are rotatably connected to the device body 1. The driven wheel 3 and the driving wheel 2 are respectively mounted on the driven shaft and the driving shaft.

[0030] A clean cleaning cloth 11 is wound on the driven wheel 3, while the driving wheel 2 is used to wind the cleaning cloth 11 that has been used to clean the glue spray valve. When the driving wheel 2 winds up the cleaning cloth 11, it will drive the driven wheel 3 to rotate and release the cleaning cloth 11.

[0031] refer to Figure 3A drive motor 14 is installed inside the device body 1. The drive motor 14 is fixed on the inner wall of the device body 1. The output shaft of the drive motor 14 is connected to the drive shaft through a drive, for example, through a coupling or gear. The drive motor 14 controls the rotation of the drive shaft, thereby driving the drive wheel 2 to rotate.

[0032] refer to Figure 1 Two cleaning tanks 8 are also installed on the front of the device body, located on the top side. The cleaning tanks 8 contain cleaning agents, and the top of the cleaning tanks 8 holds cleaning sponges 9. The cleaning tanks 8 continuously replenish the cleaning sponges 9 with cleaning agents, which are absorbed into the cleaning sponges 9.

[0033] The distance between the two cleaning tanks 8 is matched with the horizontal distance between the two glue spray valves on the dispensing machine. In other words, there is a one-to-one correspondence between the cleaning tanks 8 and the glue dispensing valves.

[0034] There are three auxiliary shafts: a first auxiliary shaft 4, a second auxiliary shaft 5, and a third auxiliary shaft 6. The first and second auxiliary shafts 4 and 5 are located between the driven wheel 3 and the cleaning tank 8, and are close to the upper edge of the front of the device body 1. The third auxiliary shaft 6 is located between the driving wheel 2 and the cleaning tank 8, and is also close to the upper edge of the front of the device body 1. All three auxiliary shafts are rotatably connected to the device body 1 and are approximately at the same height.

[0035] A tensioning shaft 7 is provided below the area between the first auxiliary shaft 4 and the second auxiliary shaft 5 for adjusting the tension of the cleaning cloth 11.

[0036] A limiting piece is provided at the front end of the three auxiliary shafts and the tensioning shaft 7 to prevent the cleaning cloth 11 from deviating. The limiting piece acts as a stop and limit, ensuring that the cleaning cloth 11 is always in contact with the outer surface of the shaft.

[0037] After the cleaning cloth 11 is released from the driven wheel 3, it will first pass over the first auxiliary shaft 4, then pass down under the tension shaft 7, then pass up over the second auxiliary shaft 5, then pass over the upper surfaces of the two cleaning sponges 9 in sequence to get wet, and finally pass down under the third auxiliary shaft 6 before being rolled up onto the drive wheel 2.

[0038] Under the action of the tensioning shaft 7, the cleaning cloth 11 will adhere tightly to the cleaning sponge 9, and the cleaning sponge 9 will soak the cleaning cloth 11 with cleaning agent. The two glue dispensing valves on the dispensing machine will move down, and the valve heads of the two dispensing valves will respectively contact the cleaning cloth 11 at the positions of the two cleaning tanks 8. During the movement, the cleaning cloth 11 will wipe off the glue on the valve heads of the dispensing valves.

[0039] like Figure 1As shown, two glue collection cups 10 are also provided inside the device body 1, with the openings of the two glue collection cups 10 facing upwards and protruding from the upper surface of the device body 1. The distance between the two glue collection cups 10 is adapted to the distance between the two glue spray valves.

[0040] Because the glue on the valve head of the glue spray valve may solidify, the two glue spray valves will spray out some glue before applying the glue, and the solidified glue will be carried away with it. The glue collection cup 10 is used to collect the glue sprayed out by the glue spray valves. After the glue spraying is completed, the two glue spray valves will move above the two cleaning tanks 8 and gradually come into contact with the cleaning cloth 11.

[0041] Under the action of the tensioning shaft 7, the cleaning cloth 11 has sufficient tension, keeping it taut. This ensures that during movement, the cleaning cloth 11 has sufficient friction to clean the valve head of the glue dispensing valve. The cleaning cloth 11 is wide enough to prevent the wiping paths of two glue dispensing valves that are staggered along its width from overlapping. Figure 1 The cleaning cloth portion that has been wiped with adhesive on the left cleaning tank 8 will not be used on the right cleaning tank 8.

[0042] refer to Figure 3 A cross-shaped baffle 16 is provided at the other end of the tensioning shaft 7 (located within the device body 1), and correspondingly, a photoelectric sensor 15 is provided within the device body 1. The photoelectric sensor 15 has a transmitting end and a receiving end. As the tensioning shaft 7 rotates, the blades of the cross-shaped baffle 16 pass between the transmitting end and the receiving end of the photoelectric sensor 15. The photoelectric sensor 15 is linked to the control system of the drive motor 14.

[0043] Every time the cross baffle 16 rotates 90°, one of the blades of the cross baffle 16 will block the signal between the transmitter and receiver of the photoelectric sensor 15. The photoelectric sensor 15 will then trigger a signal, which will be fed back to the control system of the drive motor 14. The control system will then control the drive wheel 2 to rotate approximately 1 / 4 turn each time, and the cleaning cloth 11 will be partially released.

[0044] The cross-shaped baffle 16 intermittently blocks the signal between the transmitter and receiver of the photoelectric sensor 15. The photoelectric sensor 15 can detect the number of rotations of the cross-shaped baffle 16, i.e. the number of rotations of the tension shaft 7, in this way, and indirectly measure the release length of the cleaning cloth 11. As a result, the system controls the number of rotations of the drive motor 14.

[0045] In this embodiment, the cross-shaped baffle 16 has four blades, so the cross-shaped baffle 16 will trigger a signal once every 90° rotation. In other technical solutions, the number of blades of the baffle will be increased or decreased according to the viscosity and residual amount of the adhesive. The number of blades of the baffle can be 1, 2, 3, etc., so that the baffle will trigger a signal once every 360°, 180°, or 120° rotation.

[0046] like Figure 2 As shown, a tool slot 121 is provided on the base plate 12 for placing tools, such as a cleaning bucket for holding cleaning agents, so that cleaning agents can be manually added to the cleaning bucket.

[0047] On one side of the device body 1, there is an electrical control wire connector 13, which is electrically connected to electronic components inside the device body 1, such as the control system of the drive motor 14.

[0048] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
