Description

Technical Field

[0001] The utility model relates to an anti - shrinkage protection device for the production of tourist shoes, belonging to the technical field of sole production equipment. Background Technique

[0002] Tourist shoes are comfortable and durable shoes designed specifically for travelers. Such shoes usually have characteristics such as anti - slip, shock - absorption, and breathability, and can provide sufficient support and protection during long - distance walking and on different terrains. Tourist shoes can be applied to various travel scenarios, such as hiking, city strolls, lightweight mountaineering, etc. In order to facilitate molding and manufacturing, the soles and uppers of tourist shoes are generally produced separately and then bonded and formed. In order to increase the aesthetic appearance of tourist shoes, the soles of tourist shoes generally have various different colors. Therefore, when producing the sole manufacturing materials of tourist shoes, it is necessary to first use a mixer to produce the raw rubber color materials, and then mix the raw rubber color materials with the proportioned masterbatch materials through a set of extrusion rollers of a two - roll mill to form the colored sole manufacturing materials. Finally, the manufactured sole manufacturing materials are hot - pressed into soles by sole - forming equipment.

[0003] In the prior art, when pouring the proportioned masterbatch materials onto the raw rubber color materials wrapped around the extrusion rollers of a two - roll mill, it is generally necessary to pour them directly by hand between a set of extrusion rollers. In this process, it is necessary to stretch the arm over the top of one of the extrusion rollers in a set of extrusion rollers, which poses a certain safety hazard in the addition of the masterbatch materials of the two - roll mill; at the same time, during the process of mixing and calendering the raw rubber color materials and the proportioned masterbatch materials by a set of extrusion rollers of the two - roll mill, a certain temperature is required to make the materials have a certain softness, so as to facilitate calendering and mixing.

[0033] In the above technical solution, by arranging the lifting motor 401, the rotation of the lifting motor 401 drives the driving gear 402 on its output shaft to rotate. When the driving gear 402 rotates, it can drive the driven gear 404 on one of the threaded rods 403 directly meshed therewith to rotate and the driven gear 404 on the other threaded rod 403 drivingly connected thereto through the reversing gear 405 to rotate, thereby driving the same-direction synchronous rotation of a set of threaded rods 403, and further driving the movement of the U-shaped frame 301 threadedly connected to the threaded rods 403 through the threaded holes 305, and finally achieving the purpose of driving the feed hopper 201 to move up and down.

[0034] In the present utility model, the heating mechanism 5 includes a special-shaped groove 501. One side wall of the front side of the feed hopper 201 is arranged in an irregular arc shape. An arc-shaped baffle 502 is provided near the top position on the inner wall of one side surface of the front side of the feed hopper 201. The special-shaped groove 501 is opened on the side wall of the feed hopper 201. A plurality of heating slots 503 are provided at the bottom of the special-shaped groove 501. The heating slots 503 are all located within the irregular arc-shaped side wall of the feed hopper 201, and heating wires are provided in the heating slots 503.

[0035] In the above technical solution, by opening the heating slots 503 in the special-shaped groove 501 and arranging heating wires in the heating slots 503, the heating wires can be heated to heat the irregular arc-shaped side wall near the pressing roller 7 on the front side of the feed hopper 201.

[0036] In the present utility model, a first mounting table 10 is provided on the left side of the top of the frame 1. A driving motor 11 is provided on the first mounting table 10. A second mounting table 12 is provided on the right side of the first mounting table 10. A speed reducer 13 is provided on the second mounting table 12. The output end of the driving motor 11 is in transmission connection with the input end of the speed reducer 13. The output end of the speed reducer 13 is in transmission connection with one of a set of pressing rollers 7. A control cabinet 14 is provided at the position between the second mounting table 12 and the vertical plate.

[0037] In the above technical solution, by arranging the driving motor 11 on the first mounting table 10, when the driving motor 11 starts, the speed reducer 13 installed on the second mounting table 12 is used to reduce the speed of the driving motor 11, so that when the driving motor 11 starts, it can drive one of a set of pressing rollers 7 to rotate, which can be used for the kneading of raw rubber color. By setting the controller 15, the operation start of each motor and the heating wires can be controlled.

[0038] The working principle of a shrinkage prevention and protection device for tourist shoes production in the present utility model is as follows:

[0039] In use, first, start the drive motor 11 through the controller 15. The drive motor 11 rotates and is decelerated via the speed reducer 13, and then drives one of a set of extrusion rollers 7 to rotate. Then, the raw rubber color material produced by the kneader is wound around the rotating extrusion roller 7. It should be noted that at this time, the U-shaped frame 301 is located at the upper position inside the limit groove 302. After that, the rotation motor 303 rotates forward, driving the rotating shaft 202 rotatably connected by the large bearing 203 and the small bearing 205, and further driving the feed hopper 201 to flip forward so that the side wall with the arc-shaped baffle 502 is turned parallel to the ground. At this time, the outer side wall of the feed hopper 201 provided with the heating mechanism 5 just abuts against the raw rubber color material wound around the extrusion roller 7. Then, pour the prepared color masterbatch raw material on the top of the side wall of the feed hopper 201 arranged in an irregular arc. After that, the rotation motor 303 rotates reversely and at the same time the lifting motor 401 rotates. The lifting motor 401 rotates to drive a set of threaded rods 403 to rotate synchronously in the same direction, and further drives the U-shaped frame 301 to slide downward in the limit groove 302. The rotation motor 303 rotates reversely to drive the rotating shaft 202 to rotate reversely, which can drive the feed hopper 201 to rotate. Finally, it can drive the feed hopper 201 to move downward while rotating reversely, so that the discharge port of the feed hopper 201 is directly above the position between a set of extrusion rollers 7. The color masterbatch raw material located inside the feed hopper 201 can then fall from the feed hopper 201 onto the raw rubber color material. After that, the heating wire heats up to heat the color masterbatch raw material and the raw rubber color material, prevent them from cooling and shrinking, and accelerate the mixing and calendering of the materials, and then the sole forming material of the required color can be produced.
