Description

Technical Field

[0001] The invention relates to the technical field of sole manufacturing, in particular to a rubber raw material cutting device. Background Art

[0002] Before the rubber for making the soles is refined, it is necessary to cut the required amount of rubber raw materials from large pieces, and use a hydraulic cylinder installed on the cutting knife holder to drive the cutting knife to fall and divide the raw materials. However, when the amount of raw materials to be cut is small, the side of the raw materials that are cut off is pressed down by the cutting knife, which is easy to slightly warp up and cause the cut surface to deviate, affecting the cutting effect and the processing accuracy of subsequent products. Therefore, designing a rubber raw material cutting device that can improve the accuracy of the cut surface has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a rubber raw material cutting device.

[0005] After adopting the above structure, the rubber raw material is placed on the side of the placement table where the fixed plate is not provided, and the fixed plate is rotated around the flip axis, the lower edge is flipped up toward the side where the cutting knife is located, the end of the fixed thorn is tilted upward, and then the raw material is pushed through the knife holder to be squeezed toward the fixed plate. The side of the raw material first contacts the flipped lower edge of the fixed plate, and the fixed plate is pushed to flip back to its original position. The fixed thorn is rotated downward to press into the side of the rubber raw material, and the fixed plate fits the side of the raw material to prevent the raw material from moving in the horizontal direction. At the same time, the fixed thorn rotates to generate a downward pressure force, and the fixed thorn prevents the cut side of the raw material from bending and warping, thereby ensuring the accurate position of the cutting surface and not affecting the quality of subsequent processing.

[0006] As a further improvement of the utility model, the placing table is connected to an adjusting slide rail, which is perpendicular to the cutting knife; the bottom of the rotating shaft seat is connected to the adjusting slide rail for coordinated movement, and the rotating shaft seat is provided with a threaded through hole, in which an extrusion screw is screwed, and a rotating wrench is provided at the top of the extrusion screw.

[0007] After adopting the above structure, by pushing the rotating wrench, the extrusion screw and the threaded through hole are rotated in coordination, and the extrusion screw moves downward to press on the adjusting slide rail, thereby increasing the friction force to prevent the rotating shaft seat from moving along the adjusting slide rail and maintaining the distance between the fixed plate and the cutting knife; by moving the extrusion screw upward, the rotating shaft seat can move along the adjusting slide rail and adjust the distance with the cutting knife to match the amount of raw materials to be cut.

[0008] As a further improvement of the utility model, a narrowed wedge-shaped surface is provided on one side of the fixing thorn facing the bottom end of the fixing plate.

[0009] After adopting the above structure, the wedge-shaped surface is set by the fixing thorn, which reduces the contact area with the raw material and increases the pressure, so that the fixing thorn can be pressed into the rubber raw material more easily to complete the fixation.

[0010] As a further improvement of the present invention, a roller groove is provided on the other side of the placement table relative to the fixed plate, and an auxiliary roller parallel to the fixed plate is provided in the roller groove.

[0011] After adopting the above structure, the rubber material is pressed on the auxiliary roller, and the auxiliary roller rotates in coordination when the material is pushed through the knife holder, thereby reducing the friction force on the material and making it easier to push the material through the knife holder to squeeze the fixed plate.

[0012] As a further improvement of the present invention, a lifting plate is connected to the lower edge of the fixing plate, and the lifting plate extends toward the placement table.

[0013] After adopting the above structure, after the raw material is cut, the fixed plate is rotated around the flip axis to make the lifting plate tilt upward and press against the bottom surface of the raw material, and continue to flip upward, pushing the raw material to flip in the direction away from the cutting knife, avoiding friction with the cutting knife to generate resistance when removing the raw material.

Both ends of the turning shaft 7 are provided with a rotating shaft seat 8 connected to the placing table 1, and the fixing spikes 6 are perpendicular to the fixing plate 5.

[0018] The rubber raw material is placed on the side of the placement table 1 where the fixed plate 5 is not provided, and the fixed plate 5 is rotated around the flip axis 7, the lower edge is flipped up toward the side where the cutting knife 2 is located, and the end of the fixed thorn 6 is tilted upward, and then the raw material is pushed through the knife holder 3 to be squeezed toward the fixed plate 5. The side of the raw material first contacts the flipped lower edge of the fixed plate 5, and the fixed plate 5 is pushed back to its original position. The fixed thorn 6 is rotated downward and pressed into the side of the rubber raw material. The fixed plate 5 fits the side of the raw material to prevent the raw material from moving in the horizontal direction. At the same time, the fixed thorn 6 rotates to generate a downward pressure force. The fixed thorn 6 prevents the cut side of the raw material from bending and warping, thereby ensuring the accurate position of the cutting surface and not affecting the quality of subsequent processing.

[0020] By pushing and rotating the wrench 12, the extrusion screw 11 is rotated in coordination with the threaded through hole 10, and the extrusion screw 11 moves downward to press on the adjusting slide rail 9, thereby increasing the friction force to prevent the rotating shaft seat 8 from moving along the adjusting slide rail 9, thereby maintaining the distance between the fixed plate 5 and the cutting knife 2; by moving the extrusion screw 11 upward, the rotating shaft seat 8 can move along the adjusting slide rail 9, and the distance with the cutting knife 2 is adjusted to match the amount of raw materials to be cut.

[0021] The fixing thorn 6 is provided with a narrowed wedge-shaped surface on one side facing the bottom end of the fixing plate 5 .

[0022] By setting a wedge-shaped surface on the fixing thorn 6, the contact surface with the raw material is reduced, and the pressure is increased, so that the fixing thorn 6 can be pressed into the rubber raw material more easily to complete the fixing.

[0023] A roller groove is further provided on the other side of the placing platform 1 relative to the fixing plate 5 , and an auxiliary roller 13 parallel to the fixing plate 5 is provided in the roller groove.
