Description

Technical Field

[0001] This invention relates to the field of shoe sole coating equipment and production process technology, and more specifically to a side-coated popcorn shoe sole and its production equipment and production process. Background Technology

[0002] The midsole of popcorn shoes is made of lightweight materials, making them light and comfortable to wear without putting too much burden on the feet. However, popcorn shoe midsoles also have some drawbacks, such as being prone to attracting dust and dirt, requiring frequent cleaning and maintenance. In particular, once the edges of the shoes get dirty, it can easily affect the appearance and hygiene of the shoes.

[0003] Currently, there is a lack of research on side-coated popcorn shoe soles in the market, which led to this case. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems by providing a side-coated popcorn shoe sole, its production equipment, and production process.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] A side-coated popcorn shoe sole includes a sole with a protective film on the side of the sole.

[0007] The protective film is made of one of the following materials: TPU, mesh fabric, or fibrous material.

[0008] A production equipment for side-coated popcorn shoe soles includes a machine base, a servo motor mounted on the machine base, a sub-mold connected to the output end of the servo motor, a pressing cylinder mounted on the machine base, a fixed plate fixedly connected to the piston end of the pressing cylinder, a turntable rotatably connected to the fixed plate via a bearing, a mother mold bolted to the turntable and disposed opposite to the sub-mold, a pressure roller disposed above the sub-mold, a guide film box, a hot air gun disposed above the guide film box, and a sliding assembly.

[0009] The protective film is installed inside the guide film box. A fixing plate is installed on the side wall of the guide film box. A fixing shaft is movably connected to the bottom of the fixing plate through a bearing. The fixing shaft is fixedly sleeved with the pressure roller.

[0010] The sliding assembly includes a slide rail fixedly mounted on the machine base, a slide block slidably connected to the slide rail, and a pressure rod that drives the slide block to slide up and down along the slide rail. An L-shaped plate is welded to one side of the slide block. The horizontal part of the L-shaped plate is bolted to the guide film box, and the vertical part of the L-shaped plate is used to install the hot air gun. The air outlet of the hot air gun is located near the discharge port of the guide film box. A mounting base is bolted to the other side of the slide block. A fastening seat is provided on the top of the mounting base. The bottom of the fastening seat is rotatably connected to the mounting base. An insertion hole is provided on the top of the fastening seat. The insertion hole is fixedly fitted with the pressure rod. A gas strut is provided at the bottom of the mounting base. One end of the gas strut is rotatably connected to the mounting base through a pin, and the other end of the gas strut is hinged to the machine base. The discharge port of the guide film box is the rear end port of the guide film box.

[0011] The space between the master mold and the sub-mold is used to place the shoe sole. The master mold is brought close to the sub-mold by the pressing cylinder to press the shoe sole onto the sub-mold. The shoe sole is rotated by the servo motor. The pressing rod drives the pressing roller to press the protective film on the side of the shoe sole.

[0012] The output end of the servo motor is fixedly fitted with a fixed frame, and a connecting plate is screwed onto the fixed frame. The connecting plate is screwed onto the sub-mold.

[0013] The size of the master mold and the child mold is 2-3 sizes smaller than the shoe sole.

[0014] Both the mother mold and the daughter mold have a rubber anti-slip layer on their inner sides.

[0015] Limiting components are provided on both sides of the pressing cylinder. Each limiting component includes a limiting seat connected to the side wall of the pressing cylinder. The limiting seat has a sliding hole, and a sliding rod is inserted through the sliding hole. One end of the sliding rod is mounted on a fixed plate.

[0016] The guide film box is open from front to back, and the front and rear ends of the guide film box are respectively provided with guide components. The guide components include two guide rollers that are arranged in contact with each other, and the protective film is inserted between the guide rollers.

[0017] A fixing rod is installed on the machine base, and a roll of the protective film is sleeved on the fixing rod.

[0018] A manufacturing process for a side-coated popcorn shoe sole includes the following steps:

[0019] Step 1) Secure the sole

[0020] Place the sole between the mother mold and the child mold, activate the clamping cylinder, and the clamping cylinder will push the mother mold to fix the sole onto the child mold;

[0021] Step 2) Apply protective film

[0022] The protective film is threaded between the guide rollers and extends from the front end of the guide film box to the rear end of the guide film box. At the same time, the hot air gun heats the pulled-out protective film, causing the hot melt adhesive on the protective film to melt and become sticky. Then, the protective film is pulled out and the front end of the protective film is attached to the side of the sole.

[0023] Step 3) Rolling out the protective film

[0024] Manually press down the pressure rod to make the pressure roller come into contact with the side of the sole to press the protective film. Then start the servo motor to drive the sole to rotate, and the pressure roller rolls along the side of the sole.

[0025] Step 4) Hot pressing

[0026] Place the sole obtained in step 3) into the molding mold, place the molding mold in the hot press, and perform molding processing in the hot press to obtain the final coated sole.

[0027] In step 2), the hot air gun heats the protective film at a temperature of 500-800℃; in step 4), the hot press heats the film at a temperature of 160-170℃ for 300-400 seconds, and cools the film at a temperature of 20-40℃ for 300-400 seconds.

[0028] The beneficial effects of this invention are as follows:

[0029] The sole has a protective film on the side, which is easy to clean and maintain, and has excellent weather resistance and durability. When designing patterns on the side of the sole, the pattern can be transferred onto the protective film, avoiding painting, which is more economical and environmentally friendly. The production equipment and process for this side-coated popcorn sole has fewer steps, is simple to operate, saves manpower, and reduces production costs. Attached Figure Description
