Description

Technical Field

[0001] This utility model relates to a glue-applying device, belonging to the field of shoemaking technology, specifically a glue-applying device with controllable glue output. Background Technology

[0002] In shoe manufacturing, different parts of the shoe need to be coated with glue. The quality of this coating directly affects subsequent processes and the final product quality. Some coating processes, especially those requiring precise handling, involve workers using a hand-held applicator to apply glue to specific areas. However, in current technology, the glue output from the applicator is usually uncontrollable and unadjustable. Generally, the glue output of the applicator is set to be relatively large. When a smaller amount of glue is needed, the excessive output causes glue to overflow, affecting product quality. In this case, a separate process is required to remove the overflowing glue, which increases the workload for workers, wastes glue materials, and reduces production efficiency. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a glue application device with controllable glue output, which can precisely control the glue output from the glue application tube to achieve the purpose of applying glue in small quantities, thereby improving production efficiency and product quality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A glue application device with controllable glue output includes a glue application tube, an installation cylinder, a glue leakage plate, a sealing component, and a glue output control mechanism. The glue application tube has a glue inlet and a glue outlet at both ends along its axial direction. An installation cylinder with a closed upper end is fixedly installed inside the glue application tube, and the installation cylinder is fixedly connected to the inner wall of the glue application tube via a connecting frame. A glue leakage plate for separating the inner wall of the glue application tube is fixedly installed near the glue outlet end inside the glue application tube. The edge of the glue leakage plate is fixedly connected to the inner wall of the glue application tube, and a plurality of glue leakage holes are evenly opened on the glue leakage plate. A glue output control mechanism that can move along the axial direction of the glue application tube is provided inside the installation cylinder. The lower end of the glue output control mechanism is fixedly connected to the sealing component, and the sealing component abuts against the glue leakage plate. The sealing component can partially block the glue leakage holes on the glue leakage plate.

[0005] As a limitation of this utility model: the adhesive dosage control mechanism includes an operating lever, a pushing block, a moving block, a moving plate, a guide rod, a spring, a connecting rod, and a sealing plate, wherein the pushing block, moving block, moving plate, guide rod, and connecting rod are arranged sequentially from top to bottom; the operating lever is horizontally slidable, with one end placed inside the mounting cylinder and fixedly connected to the pushing block, and the other end passing through the mounting cylinder and the adhesive application tube in sequence; the moving block is fixedly mounted on the moving plate, which can slide up and down along the inner wall of the mounting cylinder, and the pushing block abuts against the moving block with the contact surface being inclined; a sealing plate is fixedly mounted at the lower end of the mounting cylinder to seal the mounting cylinder, and several guide rods fixedly mounted at the lower end of the moving plate pass through the sealing plate and are fixedly connected to the connecting rod, which can slide up and down along the inner wall of the mounting cylinder, with the lower end of the connecting rod fixedly connected to the sealing component; a spring is sleeved on the guide rod, with both ends of the spring abutting against the moving plate and the sealing plate respectively.

[0006] As a limitation of this utility model, the number of guide rods is 1 to 4.

[0007] As a limitation of this utility model: the closed end of the upper end of the mounting cylinder is an upwardly convex conical surface.

[0008] As a limitation of this utility model: the glue-straining plate has a downwardly convex arc surface structure, and the lower end surface of the sealing component has a downwardly convex arc surface structure corresponding to the glue-straining plate.

[0009] As a limitation of this utility model: the end where the adhesive outlet is located is a downwardly convex conical surface, and a brush is fixedly provided at the adhesive outlet.

[0010] As a limitation of this utility model: the glue quantity control mechanism is located on the central axis of the glue application tube.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0012] (1) The glue quantity control mechanism provided in the glue coating tube cavity of this utility model can control the glue output of the glue coating tube. In some processes, when the required glue quantity is small, the worker holds the glue coating tube to apply glue while pressing the operating rod to seal the part of the glue leakage hole, thereby achieving the purpose of reducing the glue output, avoiding the problem of excessive glue quantity overflow affecting product quality, saving raw materials, and improving production efficiency.

[0013] (2) The glue quantity control mechanism of this utility model adopts the cooperation of a push block that can only move in the horizontal direction and a moving block that can only move in the vertical direction to realize the up and down movement of the sealing component. When the spring on the guide rod is not compressed, there is a gap between the sealing block and the glue leakage plate. At this time, the glue output is the maximum. When the operating rod is pressed, the sealing component moves down to seal part of the glue leakage hole, and the glue output becomes smaller. The whole operation process is simple and quick. The worker can control the glue output while applying glue.

[0014] (3) The top of the mounting cylinder of this utility model is set as a conical surface, which can guide the glue to flow to both sides of the glue application tube axis, improve the fluidity of the glue inside the glue holding tube, and prevent the glue from being distributed only in the middle part of the brush at the outlet, resulting in uneven glue application; and the mounting cylinder and glue quantity control mechanism are both located on the central axis of the glue application tube, so that the sealing part can seal the glue leakage hole in the center of the glue leakage plate. Combined with the conical end design at the lower end of the glue application tube, it further guides the glue to flow evenly to the brush at the glue outlet. When the brush at the glue outlet is wider, it can prevent the glue from being distributed only in the middle part of the brush.

[0015] (4) The glue-straining plate of this utility model can be designed as a planar structure or an arc surface structure with a certain curvature according to different production requirements. The number, shape, distribution state of the glue-straining holes and the effective sealing area of ​​the sealing components can be adjusted according to different production conditions, which can meet the requirements of different processes and different glue application amounts.

[0016] In summary, this utility model has a simple structure and is easy to operate. The amount of glue dispensed from the glue applicator can be controlled by pressing the operating lever, making it suitable for various glue application processes. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of this utility model are described below with reference to the accompanying drawings. It should be understood that the adhesive applicator with controllable adhesive output described herein is a preferred embodiment and is only used for illustration and explanation of this utility model, and does not constitute a limitation thereof.

[0022] The directional terms or positional relationships used in this utility model, such as "upper" and "lower," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0023] This implementation example Figure 1 , Figure 2 As shown, this is a glue application device with controllable glue output, including a glue application tube 1, a mounting cylinder 2, a glue leakage plate 3, a sealing component 4, and a glue quantity control mechanism. The glue application tube 1 is tubular, with a glue inlet 11 and a glue outlet 12 at its two ends along its axial direction. The end with the glue inlet 11 is the upper end, and the end with the glue outlet 12 is the lower end. The glue inlet 11 is connected to a glue supply device (not shown in the figure). A brush 6 is fixed at the glue outlet 12, and the end of the glue outlet 12 is a downwardly convex conical surface with the brush 6 located at the tip. During glue application, the worker holds the glue application tube 1, and the glue supply device continuously supplies glue. The glue flows out from the brush 6 at the glue outlet 12 for application.

[0024] An installation cylinder 2 with a closed upper end is fixedly installed inside the cavity of the glue application tube 1. The installation cylinder 2 is fixedly connected to the inner wall of the glue application tube 1 by a connecting bracket 21. Preferably, the installation cylinder 2 is located in the middle or upper part of the glue application tube 1, and the installation cylinder 2 is on the central axis of the glue application tube 1. The closed end of the upper end of the installation cylinder 2 is set as an upwardly convex conical surface. The conical surface structure can guide the glue liquid to flow to both sides of the glue application tube 1 after entering from the inlet, improve the fluidity of the glue liquid inside the glue tube, and prevent the glue liquid from being distributed only in the middle part of the brush 6 at the outlet, resulting in uneven glue application.

[0025] A glue-straining plate 3 is fixedly installed inside the glue-coating tube 1 near the glue outlet 12. The glue-straining plate 3 serves to separate the inner wall of the glue-coating tube. The edge of the glue-straining plate 3 is fixed to the inner wall of the glue-coating tube 1. A plurality of glue-straining holes 31 are evenly opened on the glue-straining plate 3. The glue enters the glue-coating tube 1 from the glue inlet 11, passes through the glue-straining holes 31 on the glue-straining plate 3, and then flows out through the glue outlet 12. The shape of the glue-straining plate 3 can be designed as a planar structure or an arc-shaped structure with a certain curvature according to different production requirements. In this embodiment, the glue-straining plate 3 is preferably designed as a downwardly convex arc-shaped structure, which can increase its contact area with the glue. The number, shape, and distribution of the glue-straining holes 31 can be adjusted according to different production conditions to meet the requirements of different processes and different glue coating amounts.

[0026] An adhesive quantity control mechanism that can move axially along the adhesive application tube 1 is provided inside the mounting cylinder 2. The lower end of the adhesive quantity control mechanism is fixedly connected to the sealing member 4, which abuts against the adhesive leakage plate 3. The shape of the sealing member 4 matches the shape of the abutment part of the adhesive leakage plate 3. The sealing member 4 can partially block the adhesive leakage hole 31 on the adhesive leakage plate 3. The effective sealing area of ​​the sealing member 4 can be adjusted according to different production conditions. The sealing member 4 can move up and down under the drive of the vertically movable adhesive quantity control mechanism. When the sealing member 4 is in the highest position, there is a gap between it and the adhesive leakage plate 3, which does not reduce the amount of adhesive. When it moves to the lowest position, it abuts against the adhesive leakage plate 3, blocking the adhesive leakage hole 31 to reduce the amount of adhesive.

[0027] Specifically, the adhesive dosage control mechanism in this embodiment includes an operating lever 51, a push block 52, a moving block 53, a moving plate 54, a guide rod 55, a spring 56, a connecting rod 57, and a sealing plate 58. Inside the mounting cylinder 2, the push block 52, moving block 53, moving plate 54, guide rod 55, and connecting rod 57 are arranged sequentially from top to bottom. The operating lever 51 is horizontally slidable, with one end placed inside the mounting cylinder 2 and fixedly connected to the push block 52, and the other end passing through the mounting cylinder 2 and the adhesive application tube 1. The moving block 53 is fixedly mounted on the moving plate 54, which can slide up and down along the inner wall of the mounting cylinder 2. The push block 52 and the moving block 53 abut against each other, and the contact surface is an inclined plane. The push block 52 can only move horizontally under the push of the operating lever 51, and the moving block 53 can only move vertically under the push of the inclined plane of the push block 52. A sealing plate 58 is fixed to the lower end of the mounting cylinder 2 to seal it. Several guide rods 55 fixed to the lower end of the moving plate 54 pass through the sealing plate 58 and are fixed to a connecting rod 57 that can slide up and down along the inner wall of the mounting cylinder 2. The lower end of the connecting rod 57 is fixed to the sealing component 4. A spring 56 is sleeved on the guide rod 55, and the two ends of the spring 56 abut against the moving plate 54 and the sealing plate 58 respectively. The number of guide rods 55 can be 1 to 4. When the spring 56 on the guide rod 55 is not compressed, there is a gap between the sealing block and the glue-leaking plate 3, and the glue output is at its maximum. When the operating rod 51 is pressed, the sealing component 4 moves downward to seal the glue-leaking hole 31, and the glue output decreases. The whole operation process is simple and quick, and the worker can control the glue output while applying glue.

[0028] The vertical position of the mounting cylinder 2 determines the location of the glue quantity control mechanism in the middle or upper part of the inner cavity of the glue application tube 1. At this time, the end of the operating rod 51 extending out of the glue application tube 1 is located in the middle or upper part of the glue application tube 1. The operating rod 51 is flush with the worker's palm (fingers), which facilitates the control of the operating rod 51 during glue application. The position of the mounting cylinder 2 on the central axis of the inner cavity of the glue application tube 1 determines that the glue quantity control mechanism is also located on the central axis of the glue application tube 1. This allows the sealing part 4, which is fixed to the glue quantity control mechanism, to seal the glue leakage hole 31 at the center of the glue leakage plate 3. Combined with the tapered end design at the lower end of the glue application tube 1, this further guides the glue to flow evenly onto the brush 6 at the glue outlet. When the brush 6 at the glue outlet is wide, it can prevent the glue from being distributed only in the middle part of the brush 6.

[0029] When using this embodiment, apply glue by holding the glue applicator 1. When the required amount of glue is small, press the operating lever 51 with your palm or fingers. The operating lever 51 drives the push block 52 to move horizontally to the left, thereby pushing the moving block 53, which is in contact with the inclined surface of the push block 52, to move downward. The moving plate 54, guide rod 55, and connecting rod 57 all move downward, ultimately pushing the sealing member 4 downward and sealing part of the glue leakage hole 31 on the glue leakage plate 3. Figure 2 As shown, spring 56 is in a compressed state at this time. After the glue application is completed, the palm or fingers are released, and the elastic force of spring 56 returns to its initial state, pushing the moving plate 54 upward, which in turn drives the guide rod 55 and the connecting rod 57 to move upward. At this time, the push block 52 drives the operating rod 51 to move horizontally to the right. Finally, the sealing part 4 is driven upward by the glue quantity control mechanism and leaves the glue leakage plate 3, and the glue output returns to the maximum glue output.
