Description

Technical Field

[0001] This utility model relates to the field of vulcanized shoe production technology, specifically to an auxiliary device for applying adhesive to vulcanized shoes. Background Technology

[0002] In the manufacturing process of vulcanized shoes, one step involves applying glue to the upper and sole. Traditionally, the worker holds the shoe last in one hand, rotating it with their wrist, while using a glue brush in the other to apply glue to the upper and sole. To improve efficiency, existing systems typically use auxiliary devices to secure and support the shoe last, reducing workload. A search revealed Chinese Patent Publication No. CN211581778U, which discloses an auxiliary device for applying glue to vulcanized shoes. This device includes a clamp, a drive component, a base, and a foot switch. When glue application is needed, the shoe last is placed on the clamp, and the drive component opens the clamp, securing the shoe last firmly. Then, the glue is applied using… The drive mechanism allows for rotation, specifically the synchronous rotation of the pawls on the drive mechanism. The shoe last is held and rotated, allowing for the application of glue to the upper and sole. Throughout the glue application process, the shoe last and the shoe fitted with it are firmly supported, eliminating the need for manual wrist rotation. Workers can focus on brushing along the marked lines on the shoe, without worrying about the shoe last swaying and affecting the accuracy of the glue application. This stabilizes the glue application quality, improves efficiency, and reduces the physical strain of holding the shoe last. When the glue line can be controlled effectively, the defect rate can be reduced, minimizing shoe cleaning work and avoiding unnecessary contamination.

[0003] While the above technical solution can reduce the workload of operators and improve work efficiency, it requires operators to disassemble the shoe lasts and replace them with new ones after brushing, which makes the operation cumbersome, increases the workload and reduces work efficiency. Furthermore, the height of the above technical solution cannot be adjusted according to the height of different users, thus reducing its practicality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary device for vulcanizing shoe brush adhesive. This solves the problems mentioned in the background art, such as the need for operators to disassemble and replace the shoe last with a new one after brushing, which is cumbersome, increases workload, and reduces work efficiency. Furthermore, the device cannot be height-adjusted according to different users' heights, thus reducing its practicality.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a vulcanized shoe brushing auxiliary device, including a base, a rotating mechanism fixedly installed on the upper surface of the base, a lifting adjustment mechanism throughly installed on the outer surface of the rotating mechanism, an angle adjustment mechanism fixedly installed on the movable end of the lifting adjustment mechanism, and an adjustable vulcanized shoe last fixing mechanism fixedly installed at the top end of the angle adjustment mechanism.

[0006] The rotating mechanism includes a motor fixedly installed at the center of the upper surface of the base. The output shaft of the motor is fixedly connected to a rotating shaft, and a turntable is fixedly connected to the top of the rotating shaft. A protective frame that is rotatably connected to the lower surface of the turntable is fixedly connected to the upper surface of the base.

[0007] Preferably, the lifting adjustment mechanism includes a one-way lead screw that is rotatably connected to the upper surface of the turntable. A lifting ring is threaded onto the outer surface of the bottom end of the one-way lead screw. Multiple support rods are fixedly connected in a ring array on the upper surface of the lifting ring. The support rods pass through the turntable and are slidably connected to the turntable, which facilitates the adjustment of the height of the adjustable vulcanized shoe last fixing mechanism.

[0008] Preferably, a rotating wheel is fixedly connected to the top of the unidirectional lead screw, and a guide rod that is slidably connected to the lifting ring is fixedly connected to the lower surface of the turntable to facilitate guiding the lifting ring.

[0009] Preferably, the angle adjustment mechanism includes a base fixedly connected to the top of the support rod, a bottom plate rotatably connected to the top of the base, a bracket fixedly connected to the upper surface of the bottom plate, a connecting block rotatably connected to the outer surface of the bracket, a plurality of first levers fixedly connected to the outer surface of the bottom plate, and second levers symmetrically rotatably connected to both sides of the outer surface of the bracket, with one end of the second lever rotatably connected to the center of the outer surface of the connecting block, facilitating the change of the angle of the adjustable vulcanized shoe last fixing mechanism.

[0010] Preferably, a first torsion spring (not shown in the figure) is fixedly connected between the base and the bottom plate, and a second torsion spring (not shown in the figure) is fixedly connected between the bracket and the connecting block, so as to facilitate the automatic reset of the adjustable vulcanized shoe last fixing mechanism.

A bidirectional lead screw is rotatably connected through the interior of the rectangular frame. Two sliders that are symmetrically threaded to the outer surface of the bidirectional lead screw and slidably connected to the inner wall of the rectangular frame are connected to the outer surface of the bidirectional lead screw. A spring is fixedly connected to one side of the slider, and a clamping plate for clamping the vulcanized shoe last is fixedly connected to the other end of the spring. The bottom end of the clamping plate is slidably connected to the inner wall of the rectangular frame. The outer surfaces of the top of the clamping plate, which are far apart from each other, are provided with inclined surfaces. An anti-slip pad is fixedly connected to the outer surface of the clamping plate. A knob is fixedly connected to one end of the bidirectional lead screw, which can change the distance between the two clamping plates, thereby clamping vulcanized shoe lasts of different sizes.

[0012] This utility model provides an auxiliary device for vulcanizing shoe adhesive. It has the following beneficial effects:

[0013] 1. This vulcanized shoe glue-applying auxiliary device, through its rotating mechanism and adjustable vulcanized shoe last fixing mechanism, allows the motor to rotate and switch the position of the adjustable vulcanized shoe last fixing mechanism at the top. This enables the removal of vulcanized shoes that have already been glued and the delivery of vulcanized shoes to be glued, thus achieving automatic feeding and improving work efficiency. This solves the problem of existing devices where the glue applicator needs to disassemble the shoe last, replace it with a new last, and fix it after glue application, resulting in cumbersome operation, increased workload, and reduced work efficiency.

[0014] 2. This vulcanized shoe adhesive brushing auxiliary device, through its lifting adjustment mechanism and adjustable vulcanized shoe last fixing mechanism, allows the unidirectional screw rotation to drive the lifting ring to rise and fall, which in turn drives the adjustable vulcanized shoe last fixing mechanism to rise and fall via the support rod. This allows the height of the adjustable vulcanized shoe last fixing mechanism to be changed to accommodate users of different heights, improving practicality and solving the problem that existing devices cannot adjust the height of the device according to the height of different users, thus reducing practicality.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: As Figure 1 and Figure 2 As shown, the vulcanized shoe glue-applying auxiliary device includes a base 1. A rotating mechanism 2 is fixedly installed on the upper surface of the base 1. The rotating mechanism 2 includes a motor 21 fixedly installed at the center of the upper surface of the base 1. The output shaft of the motor 21 is fixedly connected to a rotating shaft 22. A turntable 23 is fixedly connected to the top of the rotating shaft 22. A protective frame 24, which is rotatably connected to the lower surface of the turntable 23, is fixedly connected to the upper surface of the base 1. In use, the motor 21 rotates, driving the rotating shaft 22 and the turntable 23 to rotate, thereby switching the position of the adjustable vulcanized shoe last fixing mechanism 5 at the top. This allows vulcanized shoes that have already been glued to be sent away and vulcanized shoes waiting to be glued to be sent in, thus realizing automatic feeding operation, improving work efficiency, and solving the problem that existing devices require the glue applicator to disassemble the shoe last, replace it with a new shoe last, and fix it after glue application, resulting in cumbersome operation, increased workload, and reduced work efficiency.

[0021] Example 2: Figure 1 and Figure 2As shown, a lifting adjustment mechanism 3 is installed through the outer surface of the rotating mechanism 2. The lifting adjustment mechanism 3 includes a one-way screw 31 that is rotatably connected to the upper surface of the turntable 23. A lifting ring 33 is threadedly connected to the outer surface of the bottom end of the one-way screw 31. Multiple support rods 34 are fixedly connected in a ring array on the upper surface of the lifting ring 33. The support rods 34 pass through the turntable 23 and are slidably connected to the turntable 23. A rotating wheel 32 is fixedly connected to the top end of the one-way screw 31. A guide rod 35 that is slidably connected to the lifting ring 33 is fixedly connected to the lower surface of the turntable 23. The rotation of the rotating wheel 32 drives the one-way screw 31 to rotate, thereby driving the lifting ring 33 to rise and fall. In turn, the support rods 34 can drive the adjustable vulcanized shoe last fixing mechanism 5 to rise and fall, which can change the height of the adjustable vulcanized shoe last fixing mechanism 5 to adapt to users of different heights, improve practicality, and solve the problem that existing devices cannot adjust the height of the device according to the height of different users, thus reducing practicality.

[0022] Example 3: As Figures 1 to 3 As shown, the movable end of the lifting adjustment mechanism 3 is fixedly installed with an angle adjustment mechanism 4. The angle adjustment mechanism 4 includes a base 41 fixedly connected to the top of the support rod 34. The top of the base 41 is rotatably connected to a bottom plate 42. The upper surface of the bottom plate 42 is fixedly connected to a bracket 43. The outer surface of the bracket 43 is rotatably connected to a connecting block 44. The outer surface of the bottom plate 42 is fixedly connected to a plurality of first levers 45. The two sides of the outer surface of the bracket 43 are symmetrically rotatably connected to second levers 46, and one end of the second lever 46 is rotatably connected to the center of the outer surface of the connecting block 44. A first torsion spring (not shown in the figure) is fixedly connected between the base 41 and the bottom plate 42, and a second torsion spring (not shown in the figure) is fixedly connected between the bracket 43 and the connecting block 44. Rotating the first lever 45 can drive the adjustable vulcanized shoe last fixing mechanism 5 to rotate in the horizontal direction, and rotating the second lever 46 can drive the adjustable vulcanized shoe last fixing mechanism 5 to rotate in the vertical direction, thereby facilitating the application of glue to different positions on the shoe last. The first and second torsion springs can automatically reset.

[0023] Example 4: Figures 1 to 3As shown, an adjustable vulcanized shoe last fixing mechanism 5 is fixedly installed at the top of the angle adjustment mechanism 4. The adjustable vulcanized shoe last fixing mechanism 5 includes a rectangular frame 51 fixedly connected to the top of the connecting block 44. A bidirectional lead screw 52 is rotatably connected through the interior of the rectangular frame 51. Two sliders 53 are symmetrically threaded on the outer surface of the bidirectional lead screw 52 and slidably connected to the inner wall of the rectangular frame 51. A spring 54 is fixedly connected to one side of the slider 53, and a clamping plate 55 for clamping the vulcanized shoe last is fixedly connected to the other end of the spring 54. The bottom end of the clamp 5 is slidably connected to the inner wall of the rectangular frame 51. The outer surface of the top of the clamp 55 is provided with inclined surfaces on the opposite sides. The outer surface of the clamp 55 is fixedly connected with an anti-slip pad 56. One end of the bidirectional lead screw 52 is fixedly connected with a knob 57. Rotating the knob 57 drives the bidirectional lead screw 52 to rotate. The screw threads drive the sliders 53 on both sides and the clamp 55 to move relative to each other, so that shoe lasts of different sizes can be clamped. The spring 54 can automatically clamp the shoe, eliminating the need to rotate the bidirectional lead screw 52 every time, thus reducing the workload.

[0024] Working principle: When in use, the vulcanized shoe last is placed on top of the two clamping plates 55. Then, the gate knob 57 is turned. The rotation of the knob 57 drives the bidirectional lead screw 52 to rotate. Through the thread, the sliders 53 on both sides and the clamping plates 55 move relative to each other, so that shoe lasts of different sizes can be clamped. The spring 54 can automatically clamp the shoe lasts, eliminating the need to turn the bidirectional lead screw 52 every time, thus reducing the workload.

[0025] When applying glue, the user can rotate the first lever 45 and the second lever 46 according to the glue application position. Rotating the first lever 45 can drive the adjustable vulcanized shoe last fixing mechanism 5 to rotate in the horizontal direction, and rotating the second lever 46 can drive the adjustable vulcanized shoe last fixing mechanism 5 to rotate in the vertical direction, thus facilitating the application of glue to different positions on the shoe last, and automatically resetting under the action of the first torsion spring and the second torsion spring.

[0026] After the glue application is completed, the motor 21 is started. The rotation of the motor 21 drives the rotating shaft 22 and the turntable 23 to rotate, thereby switching the position of the adjustable vulcanized shoe last fixing mechanism 5 at the top. This allows the vulcanized shoes that have been glued to be sent away and the vulcanized shoes waiting to be glued to be sent in, thus realizing automatic feeding operation, improving work efficiency, and solving the problem that in the existing device, the glue applicator needs to disassemble the shoe last, replace it with a new shoe last, and fix it after the glue application, which causes cumbersome operation, increases workload, and reduces work efficiency.
