Description

TECHNICAL FIELD

[0001] The utility model relates to a glue brushing device, in particular to an automatic glue brushing device for shoes. BACKGROUND

[0002] In the shoemaking process, there are multiple processes that need to be brushed with glue, among which the shoe midsole brushing is to bond the midsole with other parts (such as the outsole, insole, etc.). In the traditional process, the brushing of the shoe midsole is generally done manually. This method not only has the problem of uneven brushing or glue application due to individual differences in operation, but also has the problems of low production efficiency and harm to workers' health. Therefore, the existing technology uses a mechanical glue brushing method to replace the manual glue brushing method. The main process is to apply glue to the designated glue position and then press and bond the other parts with the shoe midsole. However, due to the irregular shape of the outer edge of the shoe sole and the varying width, the glue application position may not be evenly distributed when the glue is applied. Since the distance between the glue application position and the irregular edge is not the same, the edge of the object to be glued may not be bonded due to the lack of glue, or there may be excess glue after bonding. In short, although the existing shoe glue brushing machine has replaced manual glue brushing to some extent, it still has the problems of low brushing precision and uneven glue application, which ultimately affects the bonding effect of the shoes. SUMMARY

[0003] To solve the above problems in the prior art, the utility model aims to provide an automatic glue brushing device for shoes, which can improve production efficiency while ensuring precise and uniform glue application, thereby improving the production quality of shoes.

[0004] To achieve the above-mentioned purpose, the utility model employs the following technical scheme: an automatic glue brushing device for shoes, comprising a multi-axis robot arm, a lifting rod, a glue brushing mechanism, and a control mechanism.

The glue brushing mechanism is fixed to the lower end of the lifting rod and comprises a base and a glue supply pipe. One end of the base is fixed to the lifting rod, and the other end of the base is provided with a glue supply pipe that is fixed to the base. The upper end of the glue supply pipe is provided with a glue inlet connector that communicates with an external glue supply pipe. The lower end of the glue supply pipe is provided with a glue outlet connector.

Under the control of the control mechanism, the glue-applying mechanism 3 can move in multi-dimensional space. The multi-axis robotic arm 1, the lifting rod 2, and its control system all employ existing technologies.

[0029] like Figure 2 , Figure 3As shown, the glue brushing mechanism 3 comprises a base 31, one end of which is fixedly connected with the lifting rod 2, and the other end of which is provided with a glue supply pipe 32 fixedly connected with the base 31, the upper end of the glue supply pipe 32 is provided with a glue inlet joint 321 in communication with an external glue supply pipe (not shown in the figure), and the lower end of the glue supply pipe 32 is provided with a glue outlet joint 322, the outer periphery of the glue outlet joint 322 is provided with a brush head 33, the lower end of the brush head 33 is provided with a brush 331 which can continuously contact the shoe body to be brushed with glue during the glue brushing work, and the brush head 33 and the brush 331 can conveniently receive glue and avoid glue overflow. In the embodiment, the glue supply pipe fixing portion 324 of the upper part of the glue supply pipe 32 is fixedly connected with the base 31 by bolts (not shown in the figure), and the bolts are matched with screw holes 325 to fix the glue supply pipe 32 on the base 31. A plurality of glue outlet openings 323 are formed on the glue outlet joint 322 at the lower end of the glue supply pipe 32, the glue outlet openings 323 are distributed along the outer peripheral wall of the glue outlet joint 322, or the glue outlet openings 323 penetrate the lower end of the glue outlet joint 322, or the two opening modes are combined, for example, Figure 4 As shown in the figure, the two opening modes are combined in the embodiment to make the glue outlet more uniform.

[0030] In order to make the brush 331 on the brush head 33 more uniformly apply glue during brushing, the brush head 33 is arranged to rotate along the central axis of the glue supply pipe 32, specifically, the rotation of the brush head 33 is realized by a rotary power mechanism and a hollow rotating shaft 34.

[0031] The hollow rotating shaft 34 is vertically arranged in the base 31, the outer wall of the upper end of the hollow rotating shaft 34 is rotatably connected with the base 31 by a bearing 341, at this time, the glue supply pipe 32 is arranged in the hollow cavity of the hollow rotating shaft 34 and coaxially with the hollow rotating shaft 34, the glue supply pipe fixing portion 324 of the upper part of the glue supply pipe 32 is fixed with the base 31 to fix the glue supply pipe. The brush head 33 is connected with the lower end of the hollow rotating shaft 34, and the brush head 33 can rotate with the rotation of the hollow rotating shaft 34, in the embodiment, the brush head 33 is connected with the hollow rotating shaft 34 through a connecting seat 342 fixedly arranged on the hollow rotating shaft 34. In order to facilitate replacement of the brush head 33, the brush head 33 and the connecting seat 342 are arranged in a detachable structure, and the detachable structure can be a threaded or buckle connection structure.

[0032] The rotary power mechanism provides power for the rotation of the brush head 33, and the rotary power mechanism comprises a power portion 351 (not shown in the figure) Figure 3The power unit 351 (its internal structure is not shown), first gear 352, and second gear 353 are fixed above the base 31.

The second gear 353 is fixedly sleeved on the outer wall of the hollow rotating shaft 34 located below the base 31. The first gear 352 and the second gear 353 mesh with each other. In this embodiment, the power unit 351 is a motor. The power unit 351 drives the first gear 352 to rotate, which in turn causes the second gear 353 and the hollow rotating shaft 34 fixed to it to rotate, thereby causing the brush head 33 at the lower end of the hollow rotating shaft 34 to rotate.

The vacuum regulating valve 36 adopts existing technology. Specifically, the vacuum regulating valve 36 includes an inlet and an outlet. The external glue delivery pipe is connected to the vacuum regulating valve 36 and the glue inlet connector 321 in sequence. The glue enters the vacuum regulating valve 36 through the external glue delivery pipe and then enters the glue inlet connector 321 through a section of the external glue delivery pipe. The control of the glue flow rate can enable the glue application mechanism 3 to meet the glue usage requirements of different processes.

[0034] A removable sealing cover (not shown in the figure) is provided on the outside of the brush head 33. When the device stops working, the sealing cover is put on. The sealing cover and the brush head can be connected by screwing or snapping. The removable sealing cover can prevent the glue on the brush 331 on the brush head 33 from solidifying, so that it is not necessary to replace the brush head 33 frequently.

[0035] When using this embodiment, the control mechanism is set according to the characteristics of the shoe body to be brushed. The shoe body to be brushed is placed in the corresponding placement position. The control mechanism is started, and the brush head 33 is driven by the multi-axis robotic arm 1 to fall to the appropriate position and contact the shoe body. The glue brushing mechanism 3 starts to work. The glue flows sequentially through the external glue supply pipe, glue inlet connector 321, glue supply pipe 32, glue outlet connector 322, and glue outlet 323 to the brush 331 on the rotating brush head 33. The brush 331 brushes the glue along the prescribed route under the drive of the glue brushing mechanism 3. After the glue brushing is completed, the glue brushing mechanism 3 is lifted.
