An adaptive delivery device for gluing

Abstract

This utility model discloses an adaptive conveying device for applying adhesive, applicable in the field of adhesive application. It includes a housing with supporting legs bolted to the bottom. This utility model achieves tension adjustment by rotating an adjusting head, causing a bidirectional screw to move two sliders relative to each other. This relative movement of the sliders causes a transmission rod to move a pressure plate, thus changing the elasticity of the first spring. This ensures effective conveying. When changes in the weight of the conveyed workpiece cause fluctuations in belt tension, the first spring automatically compensates through its extension and retraction, reducing maintenance. This utility model also achieves cleaning functionality by having a scraper remove adhesive from the conveyor belt surface during operation, followed by a cleaning head to remove any remaining adhesive. This ensures a clean conveyor belt and prevents adhesive hardening. Rotating the screw adjusts the pressure of the cleaning head and scraper, ensuring effective cleaning.

Description

Technical Field

[0001] This utility model relates to the field of adhesive application, and in particular to an adaptive conveying device for adhesive application. Background Technology

[0002] In the production of components in industries such as electronics, automobiles, and home appliances, the adhesive application process is a key step in ensuring the sealing, fixing, or insulation performance of products. During adhesive application, the workpiece is usually transported to the adhesive application station via a conveyor belt.

[0003] A search of Chinese patents revealed publication number CN205652720U, which discloses a composite template adhesive-coated core board conveying device. This device includes a conveyor frame, a longitudinal conveying mechanism, a transverse conveying mechanism, a core board arrival detector, and a controller. The longitudinal conveying mechanism comprises a transverse rotating shaft, conveying wheels, a chain connected to one end of the transverse rotating shaft, and a motor driving the chain. The transverse conveying mechanism includes a support frame, a support lifting drive mechanism, a longitudinal rotating shaft, and conveying wheels mounted on the longitudinal rotating shaft. The support lifting drive mechanism is mounted on the conveyor frame and can drive the support frame to move up and down. The core board arrival detector, motor, and support lifting drive mechanism are electrically connected to the controller. This invention features a simple structure. The adhesive-coated core board is conveyed by the conveyor mechanism, and the core board is highly ergonomic. Workers do not need to repeatedly bend over; they only need to stand fixedly to the side of the conveyor frame to receive the core board, reducing labor intensity and improving production efficiency.

[0004] Existing conveyor systems are inconvenient for tension adjustment. During use, the conveyor belt tension tends to loosen, causing slippage between the belt and the rotating roller, affecting conveying efficiency. Tension adjustment is necessary, but typically requires stopping the machine, removing the bolts at both ends of the rotating roller, adjusting the roller to the desired position, and then fixing it back in place. This process is cumbersome, has low precision, and can easily cause the roller to tilt, affecting performance. Furthermore, it lacks a cleaning function. During use, adhesive often adheres to the conveyor belt surface. Failure to clean this adhesive promptly affects belt cleanliness, and allowing it to harden increases cleaning difficulty, reducing practicality and making it inconvenient to use. To address these problems, we propose an adaptive conveyor device for applying adhesive. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive conveying device for applying adhesive, which has the advantages of easy tension adjustment and cleaning function.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adaptive conveying device for applying adhesive, comprising a housing, a support leg bolted to the bottom of the housing, a fixed rod bolted between the inner walls of the housing, a groove formed on the surface of the fixed rod, two sliders slidably connected to the inner wall of the groove, a bidirectional lead screw threaded between the inner walls of the sliders, and the bidirectional lead screw rotatably sleeved with the fixed rod and the inner wall of the housing, a transmission rod hinged to the surface of the bidirectional lead screw, a pressure plate hinged to the other end of the transmission rod, two guide rods slidably sleeved on the inner wall of the pressure plate, a first fixed frame bolted to one end of the guide rod, and the first fixed frame slidably connected to the inner wall of the housing, a first spring sleeved on the surface of the guide rod, and the first spring located between the pressure plate and the fixed frame, and a conveying mechanism provided inside the housing.

[0007] By adopting the above technical solution, rotating the adjusting head causes the bidirectional lead screw to drive the two sliders to move relative to each other. The relative movement of the sliders causes the transmission rod to drive the pressure plate to move, thereby changing the elastic force of the first spring. In this way, the tension can be adjusted to ensure the conveying effect. When the weight of the conveyed workpiece changes, causing the belt tension to fluctuate, the first spring automatically compensates through the amount of extension and retraction, reducing the amount of maintenance.

[0008] The present invention is further configured such that: two pressure regulating mechanisms are provided between the inner walls of the housing; a second fixing frame and a fixing seat are respectively bolted to the top of the pressure regulating mechanism; a cleaning head is slidably connected to the inner wall of the fixing seat; a first bolt is threadedly connected to the inner walls of the fixing seat and the cleaning head; a fixing pin is rotatably sleeved between the inner walls of the fixing frame; a rotating seat is threadedly connected to the surface of the fixing pin; a scraper is slidably sleeved on the inner wall of the rotating seat; a second bolt is threadedly connected between the scraper and the inner wall of the rotating seat; and a first nut is threadedly connected to the surface of the fixing pin.

[0009] By adopting the above technical solution, the adhesive on the surface of the conveyor belt is scraped off by a scraper when the conveyor belt is working, and then the residual adhesive on the conveyor belt is cleaned by a cleaning head. This achieves the purpose of cleaning, ensures the cleanliness of the conveyor belt, and prevents the adhesive from hardening. The pressure of the cleaning head and scraper can be adjusted by rotating the screw to ensure the cleaning effect.

[0010] The present invention is further configured such that: the conveying mechanism includes a first rotating roller and a second rotating roller, the first rotating roller is rotatably sleeved with the inner wall of the first fixed frame, and the second rotating roller is rotatably sleeved with the inner wall of the housing, a motor is bolted to one end of the second rotating roller, and the motor is bolted to the surface of the housing, and a conveyor belt is drivingly connected to the surfaces of the first rotating roller and the second rotating roller.

[0011] By adopting the above technical solution, a conveying mechanism is set up, in which the motor rotates and drives the rotating roller to rotate, thereby causing the conveyor belt to rotate and convey the workpiece.

[0012] The present invention is further configured such that: the pressure regulating mechanism includes a fixed plate, the fixed plate is bolted to the inner wall of the housing, the inner wall of the fixed plate is threaded with a screw, the top of the screw is rotatably connected to an adjusting plate, the inner walls of the adjusting plate and the fixed plate are slidably sleeved with a sliding rod, and the top of the sliding rod is bolted to the bottom of the fixed seat and the second fixed frame respectively, and a second spring is sleeved on the surface of the sliding rod.

[0013] By adopting the above technical solution, a pressure regulating mechanism is set up. Rotating the screw moves the regulating plate, and the movement of the regulating plate changes the elastic force of the second spring, thereby adjusting the pressure of the cleaning head and the scraper, ensuring the quality of cleaning.

[0014] The present invention is further configured such that a collection box is provided inside the housing.

[0015] By adopting the above technical solution and setting up a collection box, it is convenient to collect the scraped glue.

[0016] The present invention is further configured such that the cleaning head is made of fiber cotton material.

[0017] By adopting the above technical solution and setting the cleaning head to be made of fiber cotton, the cleaning effect is good.

[0018] The present invention is further configured such that a second nut is threaded onto the surface of the screw.

[0019] By adopting the above technical solution, the screw is fixed by setting a second nut, thereby improving stability.

[0020] The present invention is further configured such that an adjusting head is bolted to one end of the bidirectional lead screw.

[0021] By adopting the above technical solution, the adjustment head facilitates the rotation of the bidirectional lead screw, making it easy to adjust the tension.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model achieves the purpose of adjusting tension by rotating the adjusting head to drive the two sliders to move relative to each other with the bidirectional lead screw. The relative movement of the sliders causes the transmission rod to move the pressure plate, thereby changing the elastic force of the first spring. This ensures the conveying effect. When the weight of the conveyed workpiece changes, causing the belt tension to fluctuate, the first spring automatically compensates by the amount of extension and retraction, reducing maintenance.

[0024] 2. This utility model achieves the purpose of cleaning by having a scraper remove the glue from the surface of the conveyor belt during operation, and then cleaning the remaining glue on the conveyor belt with a cleaning head. This ensures the cleanliness of the conveyor belt, prevents the glue from hardening, and the pressure of the cleaning head and scraper can be adjusted by rotating the screw to ensure the cleaning effect.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1:

[0034] refer to Figure 1 , Figure 2 and Figure 3An adaptive conveying device for applying adhesive includes a housing 1. A support leg 2 is bolted to the bottom of the housing 1. A fixing rod 3 is bolted between the inner walls of the housing 1. A groove 4 is formed on the surface of the fixing rod 3. Two sliders 5 are slidably connected to the inner wall of the groove 4. A bidirectional lead screw 6 is threaded between the inner walls of the sliders 5, and the bidirectional lead screw 6 is rotatably sleeved with the fixing rod 3 and the inner wall of the housing 1. A transmission rod 7 is hinged to the surface of the bidirectional lead screw 6. A pressure plate 8 is hinged to the other end of the transmission rod 7. Two guide rods 9 are slidably sleeved on the inner wall of the pressure plate 8. A first fixing frame 10 is bolted to one end of each guide rod 9. The frame 10 is slidably connected to the inner wall of the housing 1. A first spring 11 is sleeved on the surface of the guide rod 9, and the first spring 11 is located between the pressure plate 8 and the fixed frame. The housing 1 is equipped with a conveying mechanism 12. By rotating the adjusting head 34, the bidirectional lead screw 6 drives the two sliders 5 to move relative to each other. The relative movement of the sliders 5 causes the transmission rod 7 to drive the pressure plate 8 to move, thereby changing the elastic force of the first spring 11. In this way, the tension can be adjusted to ensure the conveying effect. When the weight of the conveyed workpiece changes, causing the belt tension to fluctuate, the first spring 11 automatically compensates through the amount of extension and retraction, reducing the amount of maintenance.

[0035] refer to Figure 3 The conveying mechanism 12 includes a first rotating roller 23 and a second rotating roller 24. The first rotating roller 23 is rotatably sleeved with the inner wall of the first fixed frame 10, and the second rotating roller 24 is rotatably sleeved with the inner wall of the housing 1. A motor 25 is bolted to one end of the second rotating roller 24, and the motor 25 is bolted to the surface of the housing 1. A conveyor belt 26 is driven to the surfaces of the first rotating roller 23 and the second rotating roller 24. By setting the conveying mechanism 12, the motor 25 rotates and drives the rotating rollers to rotate, causing the conveyor belt 26 to rotate and convey the workpiece.

[0036] refer to Figure 1 and Figure 2 The housing 1 is provided with a collection box 32. The collection box 32 is provided inside the housing 1 to facilitate the collection of scraped glue.

[0037] refer to Figure 1 and Figure 3 One end of the double-acting lead screw 6 is bolted with an adjusting head 34. By setting the adjusting head 34, the double-acting lead screw 6 can be rotated to easily adjust the tension.

[0038] Example 2:

[0039] refer to Figure 2 , Figure 4 , Figure 5 and Figure 6Two pressure regulating mechanisms 13 are provided between the inner walls of the housing 1. The top of the pressure regulating mechanism 13 is respectively bolted with a second fixed frame 14 and a fixed seat 15. A cleaning head 16 is slidably connected to the inner wall of the fixed seat 15. A first bolt 17 is threadedly connected to the inner walls of the fixed seat 15 and the cleaning head 16. A fixing pin 18 is rotatably sleeved between the inner walls of the fixed frame. A rotating seat 19 is threadedly connected to the surface of the fixing pin 18. A scraper 20 is slidably sleeved to the inner wall of the rotating seat 19. A second bolt 21 is threadedly connected between the scraper 20 and the inner wall of the rotating seat 19. A first nut 22 is threadedly connected to the surface of the fixing pin 18. By scraping the glue on the surface of the conveyor belt 26 with the scraper 20 when the conveyor belt 26 is working, and then cleaning the residual glue on the conveyor belt 26 with the cleaning head 16, the cleaning function can be achieved, ensuring the cleanliness of the conveyor belt 26 and preventing the glue from hardening. The pressure of the cleaning head 16 and the scraper 20 can be adjusted by rotating the screw 28 to ensure the cleaning effect.

[0040] refer to Figure 4 The pressure regulating mechanism 13 includes a fixed plate 27, which is bolted to the inner wall of the housing 1. A screw 28 is threadedly connected to the inner wall of the fixed plate 27. An adjusting plate 29 is rotatably connected to the top of the screw 28. A sliding rod 30 is slidably sleeved between the adjusting plate 29 and the inner wall of the fixed plate 27. The top of the sliding rod 30 is bolted to the bottom of the fixed seat 15 and the second fixed frame 14, respectively. A second spring 31 is sleeved on the surface of the sliding rod 30. By setting the pressure regulating mechanism 13, rotating the screw 28 causes the adjusting plate 29 to move. The movement of the adjusting plate 29 changes the elastic force of the second spring 31, thereby adjusting the pressure of the cleaning head 16 and the scraper 20 and ensuring the quality of cleaning.

[0041] refer to Figure 5 The cleaning head 16 is made of fiber cotton, and by setting the material of the cleaning head 16 to be fiber cotton, the cleaning effect is good.

[0042] refer to Figure 4 The screw 28 has a second nut 33 threadedly connected to its surface. By setting the second nut 33, the screw 28 is fixed and its stability is improved.

[0043] Brief description of the operation: Rotating the adjusting head 34 causes the bidirectional lead screw 6 to rotate, which in turn causes the two sliders 5 to move relative to each other simultaneously. This relative movement of the sliders 5 moves the transmission rod 7, which in turn moves the pressure plate 8. The movement of the pressure plate 8 changes the elastic force of the first spring 11, thereby tensioning the conveyor belt 26 with the first rotating roller 23. This facilitates tension adjustment. When changes in the weight of the workpiece on the conveyor belt 26 cause fluctuations in the belt tension, the first spring 11 automatically compensates through its extension and retraction, achieving adaptive adjustment. During conveying, the scraper 20 removes the adhesive from the surface of the conveyor belt 26, and then the cleaning head 16 wipes and cleans the conveyor belt 26 to achieve the cleaning purpose. By loosening the first bolt 17 and the second bolt 21, the cleaning head 16 and the scraper 20 can be easily replaced and maintained. The cleaning head 16 and the scraper 20 are in close contact with the conveyor belt 26 under the action of the second spring 31, ensuring the cleaning effect. By rotating the screw 28, the adjusting plate 29 is moved. The movement of the adjusting plate 29 changes the elasticity of the second spring 31, which can adjust the pressure of the cleaning head 16 and the scraper 20, improving practicality.

[0044] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
