Description

Technical Field

[0001] This invention relates to a shoe-making device, specifically a shoe sole coating apparatus. Background Technology

[0002] The production of cold-bonded shoes typically includes the following steps: forming the upper with a last, pre-treatment of the upper with a last, pre-treatment of the sole, cold bonding of the upper and sole, as well as untying the laces, removing the last, and finishing. Currently, these steps are mostly completed manually, especially the sole adhesive application process in the "sole pre-treatment" and "cold bonding of the upper and sole".

[0003] Currently, the glue application process for shoe soles is generally done manually, which is characterized by high labor intensity and low efficiency. In practice, workers need to use a glue brush to carefully apply glue along the edge of the sole before filling the middle area, resulting in high workload and low efficiency, making it impossible to complete the task with high quality and quantity. Even with the existence of some glue application aids, it is difficult to effectively solve the aforementioned defects caused by manual glue application. For example, a Chinese utility model patent with authorization publication number CN 211932869 U discloses a precision glue application device for shoe uppers. This device directly presses the edge of the midsole surface to be glued, fixing the midsole while isolating areas that do not need glue application, allowing workers to easily apply glue to the inside of the midsole. Although this device reduces the difficulty of glue application to some extent, it does not change the fact that it is done manually, and the problem of low efficiency still exists.

[0004] In addition, manual application of glue cannot precisely control the thickness of the glue on the sole. If the glue is applied too thinly, the product is prone to coming off later. If the glue is applied too thickly, it will waste glue and reduce the comfort of wearing the product. Summary of the Invention

[0031] (1) This invention changes the manual glue application process in shoe sole coating, realizing automated production in the shoe sole coating process, and effectively solving the problems of high labor intensity, low production efficiency, and large differences in glue application quality caused by manual glue application. Specifically, in this invention, the shoe sole to be coated is clamped and fixed by a shoe sole mold clamping mechanism, the glue is prepared by a glue processing mechanism, and the glue is applied evenly to the shoe sole by an automatic glue application mechanism.

[0033] (3) The glue brushing roller in the automatic glue coating mechanism of the present invention is fixed on the left and right sides of the concave plate by means of telescopic rod and spring, which can ensure that the glue brushing roller and the surface of the shoe sole to be coated on the shoe sole mold are well attached, so as to improve the uniformity of glue application.

[0034] (4) The stirring blades and heating rods provided in the glue processing mechanism of the present invention can effectively prevent the glue in the processing tank from solidifying, so that the staff can prepare at least one working day's worth of glue at one time, avoiding equipment downtime due to untimely glue preparation, or insufficient glue application on shoe soles.

[0035] (5) In the shoe sole mold clamping mechanism of the present invention, the first clamping member and the second clamping member can move closer or further apart under the control of the ball screw assembly, so as to adapt to shoe sole molds of different lengths; and the two limiting rods in the first clamping member and the second clamping member can be adjusted in position under the action of the sliding rod and the limiting bolt, so as to adapt to shoe sole molds of different widths.

[0046] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and understanding purposes only and are not intended to limit the scope of the invention.

[0047] An embodiment of a shoe sole adhesive application device

[0048] like Figure 1 As shown, this embodiment includes a base 4 and a shoe sole mold clamping mechanism 1, an automatic glue application mechanism 2, and a glue treatment mechanism 3 fixed on the base 4. The base 4 is a cuboid structure with a cavity, and rubber pads are fixed at the four corners of the bottom. The base 4 has an opening on one side, and its cavity is divided into two layers by a partition 5 to facilitate the storage of the shoe sole mold 111.

[0049] I. Shoe Sole Mold Clamping Mechanism 1

[0050] The shoe sole mold clamping mechanism 1 is used to clamp and fix the shoe sole mold 111, on which the shoe sole to be coated with glue is mounted. For example... Figure 2 and Figure 3As shown, the shoe sole mold clamping mechanism 1 includes a recess 101, a ball screw assembly, and a clamping assembly. The recess 101 is fixed to the top surface of the base 4. Two limiting grooves 102 are formed on the recess 101 along its length, and the two limiting grooves 102 are collinear. The ball screw assembly is assembled at the bottom of the recess 101, arranged along the length of the recess 101, and the ball screw assembly passes through the limiting grooves 102 and connects to the clamping assembly on the top surface of the recess 101. The clamping assembly includes a first clamping member and a second clamping member arranged opposite to each other, and the first clamping member and the second clamping member can move closer or further apart under the drive of the ball screw assembly.

[0051] Specifically, such as Figure 3 As shown, the ball screw assembly includes a second screw 103, a second nut seat 104, and a third nut seat 105. The second screw 103 is rotatably connected to the bottom of the recess 101, positioned along the length of the recess 101, directly below the two limiting grooves 102 on the recess 101. The second screw 103 has a first helical groove and a second helical groove with opposite helical directions. The second nut seat 104 is fitted into the first helical groove region of the second screw 103 and extends from one of the limiting grooves 102 to the top of the recess 101, connecting with the first clamping member. The third nut seat 105 is fitted into the second helical groove region of the second screw 103 and extends from the other limiting groove 102 to the top of the recess 101, connecting with the second clamping member. To facilitate operation of the second screw 103, in this embodiment, one end of the second screw 103 extends to the outside of the recess 101 and is fitted with and fixed with a handwheel 106. By operating the handwheel 106, the second lead screw 103 is rotated, which causes the second nut seat 104 and the third nut seat 105 to move closer or further apart along a straight line under the limiting action of the limiting groove 102. This, in turn, causes the first clamping member and the second clamping member to move closer or further apart, so that the first clamping member and the second clamping member can adapt to clamping shoe sole molds 111 of different lengths.

[0052] The first and second clamping members in the clamping assembly have the same structure. Taking the first clamping member as an example, its structure will be described as follows: Figure 2As shown, the first clamping member includes a clamping plate 107, a sliding rod 108, a limiting rod 109, and a limiting bolt 110. The clamping plate 107 is arranged along the width direction of the recess 101, located on the top surface of the recess 101, and a groove is formed on the clamping plate 107 along its length direction. Two sliding rods 108 are provided, both slidingly disposed inside the clamping plate 107 along its length direction, and the two sliding rods 108 are arranged opposite to each other. Two limiting rods 109 are provided, each fixedly connected to the outer end of one sliding rod 108, and the first limiting rod 109 and one sliding rod 108 form an "L" shape structure. Two limiting bolts 110 are also provided, each limiting bolt 110 passing through the groove and threadedly connected to the inner end of one sliding rod 108, and the limiting bolt 110 is vertically arranged, with its bottom end able to abut against the top surface of the recess 101 to limit and fix the sliding rod 108. Loosening the limiting bolt 110 allows the sliding rod 108 to slide inside the clamping plate 107, thereby adjusting the distance between the limiting rod 109 and the other limiting rod 109 so that the two limiting rods 109 can accommodate shoe sole molds 111 of different widths. Tightening the limiting bolt 110 causes the bottom end of the limiting bolt 110 to abut against the top surface of the recess 101, thus limiting and fixing the sliding rod 108, thereby fixing the positions of the sliding rod 108 and the limiting rod 109.

[0053] It should be explained here that the clamping plate 107 in the first clamping member is connected to the second nut seat 104 in the ball screw assembly; the clamping plate 107 in the second clamping member is connected to the third nut seat 105 in the ball screw assembly. In the above description, "the outer end of the sliding rod 108" refers to the end of the sliding rod 108 that extends outside the clamping plate 107; "the inner end of the sliding rod 108" refers to the end of the sliding rod 108 located inside the clamping plate 107.

[0054] II. Automatic Glue Application Mechanism 2

[0055] The automatic glue application mechanism 2 is used to achieve uniform glue application to the shoe sole. For example...

The glue application frame 201 is fixed to the top surface of the base 4; the sliding column 202 is fixed to the glue application frame 201, horizontally positioned, and aligned with the length direction of the recessed frame 101 in the shoe sole mold clamping mechanism 1; the first lead screw 203 is rotatably connected to the glue application frame 201, parallel to the sliding column 202, and the first lead screw 203 and the sliding column 202 are located on the same horizontal plane; the first motor 204 is fixed to the glue application frame 201, and the power output end of the first motor 204 is connected to the first lead screw 203 via a coupling; the sliding plate 205... 05 is slidably connected to the slide column 202 via a slider. The slide plate 205 is also mounted on the first lead screw 203 via the first nut seat, and the slide plate 205 is located directly above the recess 101 in the shoe sole mold clamping mechanism 1. The cylinder 206 is fixed on the slide plate 205, and the power output end of the cylinder 206 is set vertically downward. The glue application component is mounted on the power output end of the cylinder 206, and the working end of the glue application component faces the shoe sole to be glued and fixed by the shoe sole mold clamping mechanism 1. The glue application component is also connected to the glue treatment mechanism 3.

[0056] Furthermore, such as Figure 5 As shown, the adhesive application assembly includes a concave plate 207 fixed to the power output end of the cylinder 206, an adhesive application nozzle 208 fixed to the bottom surface of the concave plate 207, and adhesive rollers 209 fixed to the left and right sides of the concave plate 207 and lower than the adhesive application nozzle 208. The adhesive application nozzle 208 is connected to the adhesive treatment mechanism 3 via a hose. In this embodiment, the connection structure between the adhesive roller 209 and the concave plate 207 is as follows: rectangular blocks are fixed to both ends of the concave plate 207, and a telescopic rod 210 is fixedly connected to the bottom of each rectangular block. A connecting seat is fixedly connected to the bottom of the telescopic rod 210, and the adhesive roller 209 is rotatably connected to the connecting seat. In order to make the adhesive roller 209 fit more closely to the sole of the shoe to be coated, a spring is also sleeved on the outside of the telescopic rod 210.

[0057] In this embodiment, the bottom surface of the concave plate 207 is also provided with a thickness detection sensor for detecting the adhesive coating thickness. An indicator light 211 is fixed on the top or side of the concave plate 207. The indicator light 211 is electrically connected to the thickness sensor through a controller. During operation, the thickness detection sensor detects the adhesive coating thickness in real time and transmits the signal to the controller, which then controls the corresponding indicator light 211 to be powered on, thereby providing information to the operator.
