Description

Technical Field

[0001] The invention relates to the technical field of sole forming machines, in particular to a sole forming machine for producing rubber soles. Background Art

[0002] Rubber soles refer to soles made of rubber. Rubber sole materials can be roughly divided into natural rubber or synthetic rubber. The advantage of natural rubber is that it is very soft and elastic, suitable for various sports. Indoor sports shoes are mostly made of natural rubber. Synthetic rubber is divided into wear-resistant rubber, environmentally friendly rubber, air rubber, sticky rubber, hard rubber and carbon-added rubber.

[0003] For example, "CN108606412A" is a sole shaping machine for rubber sole production, comprising a frame, a first hydraulic telescopic rod, an electric telescopic rod, a storage frame, a bracket and a support leg. A mounting plate is arranged above the frame, and the mounting plate is fixed to the frame by mounting nuts. An operating table is arranged in the middle of the frame, and an electric heating plate is arranged inside the operating table, and an electric heating wire is arranged inside the electric heating plate, and a shaping mold is arranged above the electric heating plate, and a limiting hole is arranged inside the shaping mold, and connecting shafts are arranged on both sides of the shaping mold. The storage frame is arranged on the frame below the movable plate, and rollers are arranged below the storage frame, and the support leg is arranged below the frame. The sole shaping machine for rubber sole production is provided with a second hydraulic telescopic rod close to the inner upper surface of the operating table. Under the telescopic action of the second hydraulic telescopic rod, the shaping mold is pushed to move horizontally on the operating table, thereby eliminating the manual push-pull mold operation and reducing human labor;

[0004] In the prior art, the most important process in the production of rubber soles is the compaction and shaping of the soles. The sole shaping machines for rubber sole production currently on the market are designed to shape the soles by placing the rubber raw materials into a sole mold, and then pushing the mold into a heated compaction plate. After the shaping is completed, the mold is pulled out of the compaction plate, the mold is opened to take out the soles, and the sole shaping process is completed.

[0005] However, at present, when processing rubber soles, the rubber raw materials are usually placed in a mold manually, and the mold is covered and placed on a heated mechanical part. The rubber is heated and melted to fill the mold. After cooling and shaping, the mold is manually taken out and opened. Since there is a certain viscosity between the rubber and the mold, the staff needs to use tools to take the rubber out of the mold during demoulding. There are many manual operations, which is inconvenient to operate. In addition, each time the sole is processed, the previous rubber sole needs to be taken out before the next sole can be loaded and processed, which reduces the work efficiency to a certain extent. Summary of the invention

The provided rubber layer 1103 and rubber teeth 1104 greatly improve the friction between the rubber soles, thereby ensuring the stability of rolling up the rubber soles and rolling them between the two unloading wheels 11.

[0048] Working principle: When processing rubber soles, the rubber strips that have been cut and weighed in advance are placed in the barrel 8, and the barrel 8 is assembled on the fixed frame 7. In the initial state, the second mold 4 is in the unfolded state and does not contact the first mold 3. The interior of the first mold 3 is exposed to the outside. The fixed frame 7 is driven downward by the second cylinder 701 until the bottom of the barrel 8 is close to the top of the first mold 3, and the quantitative discharge mechanism is driven to drop a rubber strip in the barrel 8 smoothly into the first mold 3. The second cylinder 701 is moved upward and reset, and the second mold 4 is driven to rotate, so that the second mold 4 is flipped over to the top of the first mold 3, and the first mold 3 and the second mold 4 are just adapted. At this time, the first cylinder 701 is driven to rotate. 601 drives the shaping seat 5 to move downward, and the lower part of the shaping seat 5 squeezes the upper part of the second mold 4, so that the first mold 3 and the second mold 4 fit tightly together, and the rubber overflow during the heating process is avoided as much as possible. The shaping seat 5 has a built-in heating plate 501, and the heating plate 501 is powered on to heat the rubber strip under the second mold 4, so that the melted rubber strip fills the space between the first mold 3 and the second mold 4. At this time, the heating plate 501 is turned off and the air cooling mechanism in the shaping seat 5 is driven to cool and shape the molded rubber in the second mold 4. After a period of time, the rubber is completely shaped. At this time, the shaping seat 5 is moved upward and separated from the second mold 4, and the second mold 4 is turned over and separated from the first mold 3. The rubber after molding remains in the first mold 3. In order to ensure that the rubber is more easily retained in the first mold 3, a mold with more slots and a larger rubber contact area can be set on the turntable 2 as the first mold 3 according to the style of the rubber shoe body to be manufactured. Next, the rubber sole in the first mold 3 needs to be demoulded, and the turntable 2 is rotated to rotate the first mold 3 to a position directly below the next barrel 8. By rotating the unloading rack 9, one end provided with the unloading wheel 11 is moved to directly above the rubber sole. After the first mold 3 is separated from the second mold 4, a part of the upper part of the rubber sole is located outside the upper part of the first mold 3. At this time, the unloading wheel 11 is located on both sides of the edge of one end of the rubber sole and clamps it. By synchronously rotating the unloading wheels 11 in opposite directions, one end of the rubber sole is lifted up due to the greater friction between the unloading wheels 11 and the rubber sole, and the rubber sole is continuously rolled between the two unloading wheels 11 until the entire sole is detached from the first mold 3. At this time, the unloading rack 9 is rotated to remove the finished sole on the unloading wheel 11 to realize unloading, and the above steps are repeated. In the same position, the material is loaded into the empty first mold 3 through the barrel 8, and the turntable 2 is rotated to the next position, the second mold 4 is flipped and overlapped, the molding seat 5 is pressed down for molding, and the demoulding operation is performed, which effectively saves the labor of the staff in manually loading and unloading the rubber raw material strips and manually storing and retrieving the first mold 3 and the second mold 4, making the processing work more convenient.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
