Description

Technical Field

[0001] This utility model relates to the field of shoe processing, specifically to a shoe upper chemical coating device. Background Technology

[0002] In footwear manufacturing, the bonding process between the upper and the outsole is one of the key factors determining the quality of the finished shoe. To ensure bonding strength, the upper typically requires pretreatment, mainly including surface sanding and applying a treatment agent (or adhesive). The effectiveness of this pretreatment process directly affects the bond strength between the upper and the outsole, thus impacting the shoe's durability and performance.

[0003] In existing technologies, the traditional process for pre-treating shoe uppers typically involves conveying the uppers to different workstations via conveyor belts, where operators at each workstation apply the coating agent. Specifically, operators manually hold the uppers and use adhesive application tools to apply adhesive or treatment agent to the bonding areas. However, this traditional method suffers from low automation, limited production efficiency, insufficient quality stability, high labor costs and intensity, and difficulty in standardizing the process. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, this utility model provides a shoe upper chemical coating device, which divides the shoe upper processing area into two parts: the four sides and the bottom. The two parts are coated with glue or treatment agent by brushing, so that the chemical agent (glue or treatment agent) can be better bonded to the processing area. At the same time, an all-round drive mechanism and a roller brush drive mechanism are used to realize automatic chemical coating, thereby improving processing efficiency.

[0005] Specifically, a shoe upper coating device includes a coating box, a conveying device installed inside the coating box, the shoe upper being mounted on the conveying device via a shoe last, and a perimeter coating unit and a bottom coating unit being sequentially installed below the conveying device in the conveying direction, the shoe upper being conveyed by the conveying device to the top of the perimeter coating unit and the bottom coating unit in sequence. The surrounding agent unit includes a rotating agent brush that moves along the contour of the shoe upper processing area to apply agent around the processing area of ​​the shoe upper. The agent is a pretreatment agent or glue. The bottom-mounted agent unit includes a rotating agent roller brush that moves in a reciprocating linear motion to brush the agent to the bottom of the processing area.

[0006] Optionally, the surrounding agent unit includes a first agent box, an agent brush, a first motor that drives the agent brush to rotate, and an omnidirectional drive mechanism that drives the first motor with the agent brush to move axially. The lower part of the agent brush can contact the agent contained in the first agent box. Under the drive of the omnidirectional drive mechanism, the rotating agent brush applies the agent in the first agent box to the surrounding area of ​​the shoe upper processing area.

[0007] Optionally, there are two agent brushes arranged opposite each other and inclined toward the processing area of ​​the shoe upper.

[0008] Optionally, the omnidirectional drive mechanism includes an X-axis slide screw, a Y-axis slide screw, and a Z-axis slide screw. The X-axis slide screw is fixed to the base surface along the X-axis. The Y-axis slide screw is fixedly installed on the slider of the X-axis slide screw. The Z-axis slide screw is installed on the slider of the Y-axis slide screw via a rotating component. The Z-axis connecting plate in the rotating component is fixedly connected to the Z-axis slide screw. The first motor is fixedly installed on an inclined plate, which is fixedly connected to the slider of the Z-axis slide screw. The inclined plate is inclined towards the first medicine box. The first motor drives the medicine brush to rotate via belt drive.

[0009] Optionally, the rotating component includes a Z-axis mounting bracket, a rotating motor, and a rotating table. The Z-axis mounting bracket is fixedly mounted on the slider of the Y-axis slide screw. The rotating motor is fixedly mounted on the Z-axis mounting bracket. The rotating shaft of the rotating motor is connected to the rotating table. The rotating table is rotatably connected to the Z-axis mounting bracket. The rotating table is fixedly connected to the Z-axis slide screw through a Z-axis connecting plate.

[0010] Optionally, the bottom-mounted agent unit includes a second agent box, an agent roller brush, a second motor that drives the agent roller brush to rotate, and a roller brush drive mechanism that drives the second motor to move up and down and horizontally. The lower part of the agent roller brush can contact the agent contained in the second agent box. Under the drive of the roller brush drive mechanism, the rotating agent roller brush brushes the agent in the second agent box to the bottom of the shoe upper processing area.

[0011] Optionally, the roller brush driving mechanism includes an X-axis slide screw, an X-axis slide rail, a Z-axis slide rail, and a Z-axis slide screw. The X-axis slide screw and the X-axis slide rail are fixedly mounted parallel to each other on the base surface via an extension frame. A transfer mounting plate that can move on the X-axis slide rail is mounted on the slider of the X-axis slide screw. The Z-axis slide rail and the Z-axis slide screw are mounted parallel to the transfer mounting plate. The second motor is slidably mounted on the Z-axis slide rail, and the other end of the pharmaceutical roller brush is rotatably mounted on the slider of the Z-axis slide screw.

[0012] Optionally, the conveying device includes a conveying component, which is detachably mounted with several shoe lasts that move in the conveying direction of the conveying component; A connecting box is provided on the upper part of the shoe last. An L-shaped first suspension plate and a second suspension plate arranged in the same direction are provided on the upper end of the connecting box. A box connecting plate is installed on the conveying component, and the first and second suspension plates are suspended from the box connecting plate. The box connecting plate is connected to the first suspension plate via a locking mechanism.

[0013] Optionally, both the surrounding drug application unit and the bottom drug application unit are equipped with a sealing unit. The sealing unit includes a sealing box and a Z-axis slide screw that drives the sealing box. The Z-axis slide screw is connected to the sealing box through a sealing box connecting plate.

[0014] This utility model has the following advantages: This utility model is a shoe upper chemical coating device. The shoe upper processing area is divided into two parts: the four sides and the bottom. The two parts are coated with glue or treatment agent by brushing, so that the chemical agent (glue or treatment agent) can be better bonded to the processing area. At the same time, an all-round drive mechanism and a roller brush drive mechanism are used to realize automatic chemical coating, thereby improving processing efficiency.

[0015] The shoe last with the upper attached is conveyed to the surrounding chemical application units and the bottom chemical application unit through a conveying device to facilitate the application of the chemical and achieve automatic conveying. At the same time, the sealing unit is reasonably designed. Through the upward-moving sealing box, the chemical application process is placed in a relatively independent space to reduce the leakage of the treatment agent and avoid affecting the health of the workers.

[0016] Because the adhesive (glue or treatment agent) is highly corrosive to hoses, if a robotic arm is used to apply the adhesive, the pipes conveying the adhesive are easily corroded and leak. This invention, however, uses a rotating adhesive brush and roller brush (rotating at a certain speed, neither too fast nor too slow) to apply the adhesive to the processing area of ​​the shoe upper, thus avoiding pipe corrosion. Furthermore, this invention is carried out in a sealed coating box or sealed box, preventing workers from directly contacting the adhesive and causing occupational diseases. At the same time, the brushing method avoids the problem of clogging (because traditional adhesive application also includes spraying, and if the spraying process stops, the nozzle is very prone to clogging).

Detailed Implementation

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0020] As described in the background section, in existing technologies, the traditional process for pre-treating shoe uppers typically involves conveying the shoe uppers to different workstations via conveyor belts, where operators at each workstation apply the coating agent. Specifically, operators manually hold the shoe upper and use an adhesive brush to apply adhesive or treatment agent to the bonding areas. However, this traditional method suffers from low automation, limited production efficiency, insufficient quality stability, high labor costs and intensity, and difficulty in standardizing the process.

[0021] For the reasons mentioned above, this embodiment provides a shoe upper agent application device, such as... Figures 1-13 As shown, the device includes a coating box 300, and a conveying device 400 is installed inside the upper part of the coating box. The shoe upper 601 is installed on the conveying device through the shoe last 600. Below the conveying device, along the conveying direction, a four-sided application unit 100 and a bottom application unit 200 are installed in sequence. The shoe upper is conveyed by the conveying device and arrives above the four-sided application unit and the bottom application unit in sequence.

[0022] The surrounding application unit 100 includes a first medicine box 180, medicine brushes 170, a first motor 160 that drives the medicine brushes to rotate, and an omnidirectional drive mechanism that drives the first motor with the medicine brushes to move axially. There are two medicine brushes 170, arranged opposite each other and tilted towards the processing area 602 of the shoe upper. The lower part of each medicine brush 170 can contact the medicine contained in the first medicine box 180. To accommodate the height of the medicine brushes, the first medicine box 180 is mounted on a base surface via a column support 181. When the surrounding application unit is running, the rotating medicine brushes 170, driven by the omnidirectional drive mechanism, apply the medicine contained in the first medicine box... The agent is applied to the perimeter of the shoe upper processing area; the bottom agent unit 200 includes a second agent box 230, an agent roller brush 210, a second motor 220 that drives the agent roller brush to rotate, and a roller brush drive mechanism that drives the second motor to move up and down and horizontally. The second motor 220 is driven by the agent roller brush 210 via belt transmission. The second agent box 230 is mounted on the base surface by an agent column support 231. The lower part of the agent roller brush can contact the agent contained in the second agent box. When the bottom agent unit is running, the rotating agent roller brush, driven by the roller brush drive mechanism, brushes the agent in the second agent box onto the bottom of the shoe upper processing area.

[0023] For example, both the medicine brush and the medicine roller brush are soft bristle roller brushes, the purpose of which is to dip the medicine and brush it evenly onto the shoe surface and sole. The reason for using a brush roller is that the bristles of the brush roller have a certain degree of flexibility and are not too rigid, so that the medicine can be applied to places such as crevices.

[0024] The omnidirectional drive mechanism includes an X-axis slide screw 110, a Y-axis slide screw 120, and a Z-axis slide screw 130. The X-axis, Y-axis, and Z-axis slide screws are all existing slide screws or other existing transmission mechanisms capable of linear transmission and applicable to this application. The X-axis slide screw is fixedly mounted on the base surface along the X-axis direction, where the X-axis is the length direction of the shoe last or the conveying direction of the shoe upper on the production line. The Z-axis is longitudinal, and the Y-axis is perpendicular to the XZ plane (e.g., ...). Figure 1 As shown in the coordinate system (as shown in the figure), the X-axis slide screw described in this application is represented as a slide screw along the coordinate system shown in the figure. Figure 1The slide screw is arranged along the X-axis, and the slide screw along the Y-axis is represented as follows. Figure 1 The Y-axis slide screw is arranged in the middle, and the Z-axis slide screw is represented as follows: Figure 1 A Z-axis sliding screw is arranged in the middle. The Y-axis sliding screw is fixedly installed on the slider of the X-axis sliding screw. The Z-axis sliding screw 130 is installed on the slider of the Y-axis sliding screw 120 via a rotating component 140. The Z-axis connecting plate in the rotating component is fixedly connected to the Z-axis sliding screw 130. The first motor 160 is fixedly installed on an inclined plate 161, which is fixedly connected to the slider of the Z-axis sliding screw 130. The inclined plate 161 is inclined towards the first medicine box 180. The first motor 160 drives the medicine brush 170 to rotate via belt drive. The inclined plate enables the medicine brush to be installed at an angle, reducing the amount of medicine dripping outside the first medicine box during rotation and improving the adhesion of the medicine brush to the processing area. To prevent the sliders of the X-axis, Y-axis, and Z-axis sliding screws from moving too much and causing the medicine brush to detach from the first medicine box or the medicine, corresponding limit switches are provided. When the omnidirectional drive mechanism is working, the rotating agent brush moves around the shoe upper processing area through the X-axis slide screw, Y-axis slide screw and Z-axis slide screw to apply the agent to the shoe upper processing area. In order to better fit the rotating agent brush with the curved surface around the inclined processing area, the position of the agent brush is finely adjusted by the rotating component.

[0025] For example, the rotating component 140 includes a Z-axis mounting bracket 141, a rotating motor 142, and a rotating table 143. The Z-axis mounting bracket 141 is fixedly mounted on the slider of the Y-axis slide screw 130. The rotating motor 142 is fixedly mounted on the Z-axis mounting bracket 141. The rotating shaft of the rotating motor 142 is connected to the rotating table 143. The rotating table 143 is rotatably connected to the Z-axis mounting bracket 141. The rotating table 143 is fixedly connected to the Z-axis slide screw through a Z-axis connecting plate 144.

[0026] like Figure 9 and Figure 10As shown, the roller brush driving mechanism includes an X-axis slide screw 110, an X-axis slide rail, a Z-axis slide rail 130, and a Z-axis slide screw. The X-axis slide screw and the X-axis slide rail are fixedly mounted parallel to each other on the base surface via an extension bracket 231. A transfer mounting plate 240, which can move on the X-axis slide rail, is mounted on the slider of the X-axis slide screw. The Z-axis slide rail and the Z-axis slide screw are mounted parallel to the transfer mounting plate. The second motor is slidably mounted on the Z-axis slide rail, and the other end of the medicine roller brush (the end away from the second motor) is rotatably mounted on the slider of the Z-axis slide screw. In use, the medicine roller brush is driven to rotate by the second motor, and the second motor and the medicine roller brush move up and down on the Z-axis slide rail under the drive of the Z-axis slide screw. The Z-axis slide screw moves back and forth in the X-axis direction on the X-axis slide rail under the action of the X-axis slide screw.

[0027] To facilitate the transport of shoe lasts via a conveying device, in one embodiment, the conveying device 400 includes a conveying component (exemplarily, this conveying component may be a chain conveyor). This conveying component is detachably mounted with several shoe lasts that move in the conveying direction. To achieve a detachable connection between the conveying component and the shoe lasts, a connecting box 500 is provided on the upper part of the shoe last 600. The upper end of the connecting box is provided with an L-shaped first suspension plate 510 and a second suspension plate 520 arranged in the same direction. A box connecting plate 410 is installed on the conveying component, and the first and second suspension plates are suspended from the box connecting plate. The first and / or second suspension plates are connected to the box connecting plate via a locking mechanism, such as... Figures 14-17As shown, a locking mechanism 700 is installed on the housing connecting plate 410. This locking mechanism 700 includes a rotary motor 721, a reaming plate 724, a clamping block mounting bracket 720, two opposing clamping blocks 710, and a rotary motor mounting plate 730. The clamping block mounting bracket 720 is fixedly installed above the housing connecting plate 410. The two opposing clamping blocks 710 are slidably installed on the clamping block mounting bracket 720. A thrust spring 725 is provided between the back of each clamping block 710 and the clamping block mounting bracket 720, forming a locking area with a variable spacing between the two clamping blocks. The two thrust springs push the clamping blocks closer together. The reaming plate is located in this locking area and connected to the rotating shaft of the rotary motor. The rotary motor is mounted above the clamping block mounting bracket 720 via the rotary motor mounting plate. The shaft rotation drives the expansion plate to rotate. The expansion plate is a diamond-shaped plate or a cam. When the long side protrusion contacts and rotates with the clamping block, it pushes the two clamping blocks to separate. When the separation distance is greater than the maximum width of the first suspension plate, the first suspension plate is in the unlocked state. When the expansion plate rotates in the opposite direction, the first suspension plate is clamped in the engagement area. At this time, the engagement tenon 511 on the first suspension plate is inserted into the engagement groove 723 on the inner side of the clamping block, thereby locking the first suspension plate. To ensure the smooth movement of the two clamping blocks, a guide post 722 that cooperates with the clamping block is also provided. Optionally, the guide post 722 can be connected to the clamping block mounting frame at both ends and pass through the two clamping blocks. The rotary motor 721 has a rotating guide post 726, and a rotating guide groove 727 matching the rotating guide post is provided on the clamping block mounting frame 720. The engagement mechanism can prevent the connecting box from being accidentally knocked off.

[0028] To place the shoe last in a relatively independent and sealed production line for applying the agent, both the perimeter agent application unit and the bottom agent application unit are equipped with sealing units. Each sealing unit includes a sealing box 150 and a Z-axis slide screw 130 that drives the sealing box. The Z-axis slide screw is connected to the sealing box via a connecting plate. In use, the Z-axis slide screw of the sealing unit drives the sealing box upwards, allowing the processing area of ​​the shoe upper to enter the sealing box through the interface until the sealing strip of the sealing box contacts the connecting box. At this point, the Z-axis slide screw stops moving, sealing the edge of the interface with the sealing strip before the agent is applied. After the agent application is complete, the Z-axis slide screw of the sealing unit drives the sealing box downwards to reset.

[0029] For example, when applying a chemical to the shoe upper processing area using the aforementioned shoe upper chemical application device, the following steps are included: The shoe upper is installed on the conveying component using the shoe last, and the conveying component sequentially conveys the shoe upper to the surrounding drug application unit and the bottom drug application unit. When the shoe upper is conveyed to the surrounding chemical application unit, the Z-axis slide screw of the sealing unit drives the sealing box to move upward. The processing area of ​​the shoe upper enters the sealing box through the interface of the sealing box until the sealing strip of the sealing box contacts the connecting box. The Z-axis slide screw stops moving, and the sealing strip seals the edge of the interface. Then, the rotating chemical brush, driven by the omnidirectional drive mechanism, applies the chemical from the first chemical box to the surrounding area of ​​the shoe upper processing area. After the chemical is applied around the surrounding area, the Z-axis slide screw of the sealing unit drives the sealing box to move downward and reset. When the shoe upper is conveyed to the bottom agent unit, the Z-axis slide screw of the sealing unit drives the sealing box to move upward. The processing area of ​​the shoe upper enters the sealing box through the interface of the sealing box until the sealing strip of the sealing box contacts the connecting box. The Z-axis slide screw stops moving, and the sealing strip seals the edge of the interface. Then, the rotating agent roller brush, driven by the roller brush drive mechanism, brushes the agent in the second agent box to the bottom of the shoe upper processing area. After the agent is applied to the bottom, the Z-axis slide screw of the sealing unit drives the sealing box to move downward and reset.
