Description

Technical Field

[0001] The utility model belongs to the technical field of shoe production, in particular to a sole raw material mixing device for shoe production. Background Art

[0002] Shoes are items worn on the feet to protect the feet from injury. The common properties of general sole materials should be wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to adapt to the foot shape, not easy to deform after shaping, heat preservation, easy to absorb moisture, etc. During the production process of the sole, in order to improve the toughness and wear resistance of the sole, it is necessary to add some other auxiliary raw materials to the sole raw materials, and stir and mix all the raw materials, so as to produce better quality soles.

[0003] A Chinese utility model patent with publication number CN217962330U discloses a raw material mixing device for sole production. The sole raw materials can be sorted and combed by two dispersing rollers, the clumped raw materials in the sole raw materials can be broken up, the large pieces of sole raw materials can be crushed, and different sole raw materials can be mixed while beating the sole raw materials. The screen is used to screen the sole raw materials so that large particles and clumped sole raw materials remain on the screen. The first and second half gears are rotated alternately, so that the upper and lower positions of the dispersing box can be repeatedly reversed several times, so that the large particles and clumped sole raw materials on the screen are crushed and dispersed by the two dispersing rollers until all the sole raw materials pass through the screen. The stirring rod can perform secondary mixing on the sole raw materials, which can accelerate the mixing between the sole raw materials and improve the mixing effect of the device.

[0004] However, in the actual use of the device, some areas that need to be improved were found: it is not convenient to put multiple materials in an orderly manner, and more materials are put in at one time for mixing, which easily leads to problems such as long mixing time and insufficient mixing. In addition, it does not have a heating function, and liquefied rubber and other materials are prone to solidification and affect mixing. Therefore, it is urgent to improve the existing sole raw material mixing equipment and provide a sole raw material mixing equipment for shoe production that is convenient for adding multiple materials in an orderly manner and has a heating function.

[0038] In this embodiment, by opening the fixed column 805 and the guide groove 14, when the second feed barrel 8 rotates with the movable cover 5, the fixed column 805 can drive the sealing plate 804 to be raised and lowered, so that the raw materials in the temporary storage barrel 801 can be added in batches, which is convenient for more thorough mixing of various raw materials.

The outer side of the stirring rod 1301 is rotatably sleeved with a bracket 1303, and the other end of the bracket 1303 is welded to the inner wall of the mixing tank 1.

[0042] In this embodiment, when the worm 11 rotates, the stirring rod 1301 can be controlled to rotate through the worm gear 1302, so as to facilitate stirring and mixing of various sole raw materials in the mixing tank 1.

[0043] The working principle of the utility model is as follows:

[0044] When in use, firstly, liquid rubber and other main sole raw materials are added into the mixing tank 1 through the first feeding barrel 7, at which time the solenoid valve 3 and the discharge pipe 2 are both in a closed state, the heating plate 4 is turned on to heat the liquid rubber and other sole raw materials to prevent solidification and affect the subsequent stirring and mixing, and then the barrel cover 802 on the top of the temporary storage barrel 801 is opened, and the required multiple auxiliary sole raw materials are added to the multiple groups of second feeding barrels 8 in the specified amount in turn, and then the barrel cover 802 is closed;

[0045] After all the sole raw materials are added, the motor 10 can be turned on to control the rotation of the worm 11 and the conical gear 12. At this time, the movable cover 5, the first feed barrel 7 and the multiple groups of second feed barrels 8 can be driven to rotate at a uniform speed through the conical gear ring 6. When the fixed column 805 on the outer wall of the sealing plate 804 at the bottom end of the temporary storage barrel 801 moves and enters the "concave" section of the guide groove 14, the fixed column 805 can drive the sealing plate 804 and the square rod 806 to move vertically downward stably under the limiting action of the fixed block 807. After the sealing plate 804 moves downward, the bottom outlet of the temporary storage barrel 801 is opened, and the raw materials therein can fall into the mixing tank 1, and the sealing plate 804 is a pointed cone to prevent the raw materials from piling up at its upper end;

[0046] As the movable cover 5 continues to rotate, when the fixed column 805 re-enters the annular section of the guide groove 14, the fixed column 805 can drive the sealing plate 804 to move up and reset, and stop the discharge of raw materials. Similarly, during the continuous rotation of the movable cover 5, through the guide groove 14 and the fixed column 805, multiple groups of second feed barrel 8 bottom outlets are opened in sequence to carry out batch and orderly input of raw materials, so as to improve the speed and efficiency of mixing various raw materials for the soles, and prevent too much raw material from being added at one time and affecting the mixing effect. Moreover, when the worm 11 rotates, it can also drive the stirring rod 1301 to rotate through the worm gear 1302, so as to facilitate the mixing of various raw materials for the soles put into the mixing tank 1. After sufficient mixing, the solenoid valve 3 can be opened to discharge the raw materials for the soles through the discharge pipe 2 and collect them.

[0047] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
