Description

Technical Field

[0001] This utility model relates to the field of gluing equipment, and in particular to a gluing machine. Background Technology

[0002] In shoe manufacturing, a gluing machine is used to apply glue to the surface of shoe materials to bond different parts of the shoe together. However, in current gluing machines, the first roller is connected to the frame, and part of the first roller is immersed in the liquid storage tank. After the glue application is completed, the glue in the storage tank is poured out, and the storage tank and the first roller are cleaned. However, since the first roller cannot be moved, the available operating space between the storage tank and the first roller is small, making it inconvenient for workers to clean the storage tank and the first roller. Moreover, it is difficult to clean them completely. Residual glue may deteriorate and oxidize if exposed to air for a long time, and may affect the bonding effect when mixed with subsequent glues.

[0003] CN201810325575 discloses a shoe gluing machine, including a main body with a PLC controller inside. A glue tank is located in the middle, with supports on the upper sides of both sides of the glue tank and a hydraulic sensor at the bottom. A pressure roller and a first roller are mounted sequentially from top to bottom on the supports. A motor is located on the right side of the right support and connected to the first roller. A glue tank is located on the left side of the left support. The glue tank and glue tank are connected by a conduit, and a flow control valve is located on the conduit. The PLC controller is connected to the flow control valve and the hydraulic sensor. The first roller of this gluing machine cannot move up and down on the supports, making it difficult for workers to clean the glue tank and the first roller.

[0004] The technical problem that this utility model needs to solve is: how to more conveniently clean the liquid storage tank and the glue roller assembly. Utility Model Content

[0005] The main purpose of this utility model is to provide a gluing machine that uses a lifting unit to drive the gluing roller assembly to move up and down, allowing the gluing roller assembly to be partially immersed in or completely detached from the liquid storage tank. When the gluing machine needs to be cleaned, the gluing roller assembly can detach from the liquid storage tank and rise to a certain height, increasing the operating space for the operator, so that the operator can reach into the liquid storage tank to thoroughly clean the inside of the liquid storage tank.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

The liquid storage tank 2 is connected to the frame 1, and the glue application roller assembly 3 is located above the liquid storage tank 2. The power output end of the drive unit 4 is detachably connected to the glue application roller assembly 3. The machine also includes a lifting unit 5 connected to the frame 1. The glue application roller assembly 3 is connected to the lifting unit 5. The lifting unit 5 is used to immerse or detach the glue application roller assembly 3 from the liquid storage tank 2.

[0027] In this embodiment, the glue coating process of the glue applicator is as follows: the lifting unit 5 drives the glue roller group 3 to descend, so that the glue roller group 3 is partially immersed in the liquid storage tank 2. The driving unit 4 is connected to the glue roller group 3, and the driving unit 4 drives the glue roller group 3 to rotate. After the glue roller group 3 adheres to the glue in the liquid storage tank 2, the glue roller group 3 applies the glue to the surface of the product.

[0028] The cleaning process of the glue applicator is as follows: the drive unit 4 disconnects from the glue roller group 3, the lifting unit 5 drives the glue roller group 3 to detach from the liquid storage tank 2 and rise to a position where the worker's hand can easily reach into the liquid storage tank 2, and the worker uses cleaning tools to clean the liquid storage tank 2 and the glue roller group 3.

[0029] It should be noted that the drive unit 4 is a motor, and the drive unit 4 is disconnected from the glue roller assembly 3 by means of a clutch. The lifting unit 5 drives the glue roller assembly 3 to rise, which can increase the operating space between the glue roller assembly 3 and the liquid storage tank 2, making it easier for workers to clean the liquid storage tank 2 and the glue roller assembly 3.

[0030] Preferably, it further includes a flipping unit 6; the flipping unit 6 includes a gear 61 connected to the upper glue roller group 3 and a rack 62 and a guide post 63 connected to the frame 1; the upper glue roller group 3 is rotatably connected to the lifting unit 5; the guide post 63 is located on both sides of the upper glue roller group 3;

[0031] When the lifting unit 5 drives the upper rubber roller group 3 to rise to the position where it is disengaged from the guide column 63, the gear 61 meshes with the rack 62 to make the upper rubber roller group 3 rotate from the vertical state to the horizontal state.

[0032] In this embodiment, four guide posts 63 are provided. These guide posts 63 are positioned above the liquid storage tank 2 and contact both sides of the upper rubber roller assembly 3. Gears 61 are connected to the upper rubber roller assembly 3 and rotate together with it. When the lifting unit 5 moves the upper rubber roller assembly 3 out of or into the liquid storage tank 2, the guide posts 63 contact both sides of the upper rubber roller assembly 3 to prevent it from swaying during the lifting process. After the upper rubber roller assembly 3 leaves the liquid storage tank 2, the lifting unit 5 continues to move it upwards. After the upper rubber roller assembly 3 leaves the guide posts 63, the gears 61 mesh with the rack 62. During the upward movement of the upper rubber roller assembly 3, the gears 61 roll on the rack 62, thereby rotating the upper rubber roller assembly 3 from a vertical position to a horizontal position. Rotating the upper rubber roller assembly 3 to a horizontal position facilitates cleaning by the operator.

[0034] In this embodiment, in the vertical state, the first roller 31 and the second roller 32 are located on the same vertical plane; in the horizontal state, the first roller 31 and the second roller 32 are located on the same horizontal plane. When the drive unit 4 is connected to the first roller 31, it drives the first roller 31 to adhere the glue in the liquid storage tank 2. When the product passes through the glue application channel 34, the first roller 31 applies the glue to the lower surface of the product. After the drive unit 4 is disconnected from the first roller 31, the lifting unit 5 drives the rotating frame 33 to move upward, thereby driving the first roller 31 and the second roller 32 to move upward. The guide column 63 contacts both sides of the rotating frame 33 to prevent the rotating frame 33 from shaking during the lifting process. The lifting unit 5 drives the glue application roller group 3 to continue to move upward. The rotating frame 33 disengages from the guide column 63, and the gear 61 meshes with the rack 62, thereby causing the glue application roller group 3 to rotate to a horizontal state.

The lead screw is rotatably connected to the support frame 11, and the handwheel is connected to the end of the lead screw. The sliding block 52 is threadedly connected to the lead screw. Rotating the handwheel drives the lead screw to rotate, thereby causing the sliding block to move up and down on the support frame 11, and in turn, causing the rotating frame 33 to move up and down.

[0037] More preferably, the support frame 11 is provided with a guide rod 12, which is slidably connected to the sliding block 52. By setting the guide rod 12, the sliding block 52 can move up and down more smoothly.

[0038] Preferably, the drive unit 4 is provided with a clutch module 7; the two ends of the clutch module 7 are respectively connected to the power output end of the drive unit 4 and the first roller 31; the clutch module 7 is used to enable the drive unit 4 to be disconnected from the first roller 31.

[0039] In this embodiment, the clutch module 7 is a jaw clutch. When the drive unit 4 is connected to the first roller 31, the drive unit 4 drives the first roller 31 to rotate, thereby adhering the adhesive in the liquid storage tank 2 to the surface of the product.

[0040] Preferably, the clutch module 7 includes a first clutch 71, a second clutch 72, and a shift fork 73; the first clutch 71 is slidably connected to the power output end of the drive unit 4; the second clutch 72 is connected to the end of the first roller 31 near the drive unit 4; the shift fork 73 is rotatably connected to the frame 1, and the end of the shift fork 73 is in contact with the first clutch 71; the shift fork 73 is used to push the first clutch 71 closer to or away from the second clutch 72.

The first clutch 71 can move horizontally on the power output end of the drive unit 4 and can rotate with the power output end of the drive unit 4. When the drive unit 4 needs to connect with the first roller 31 and drive the first roller 31 to rotate, the shift fork 73 is rotated. The shift fork 73 pushes the first clutch 71 to engage with the second clutch 72, thereby enabling the drive unit 4 to drive the first roller 31 to rotate.

[0042] Preferably, the shift fork 73 has a symmetrically arranged push arm 731 at one end near the first clutch member 71; the push arm 731 is provided with a roller 732; the first clutch member 71 is provided with a push groove 711; the roller 732 is in contact with the inner wall of the push groove 711.
