Description

Technical Field

[0001] This utility model relates to cutting equipment, and more specifically, to a shoe material cutting equipment. Background Technology

[0002] In the production of finished leather shoes, large pieces of raw leather fabric need to be cut and trimmed into various shapes. The cut shoes then proceed to the next steps, such as sewing and gluing. Existing shoe material cutting equipment, due to the relatively soft nature of leather, easily causes wrinkles and unevenness in the fabric when the blade contacts it, resulting in an uneven cut surface and affecting the quality of the finished product. To address this problem, this application provides a shoe material cutting device with a positioning device at the blade tip. This reduces the impact of blade displacement on the flatness of the fabric, resulting in high-quality work and strong stability. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shoe material cutting device that can reduce the impact of the cutter head on the flatness of the fabric during cutting displacement, and has high working quality and strong stability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shoe material cutting device, including a cutting workbench and a cutting device located above the cutting workbench. The cutting device includes a support and a cylindrical cutting blade. The support is provided with a positioning device, which includes an annular positioning seat with a circular opening in the middle. The cutting blade passes through the circular opening. The upper end face of the positioning seat is provided with at least three telescopic columns, which are slidably mounted on the support. The lower end face is provided with an annular groove, in which a plurality of rolling balls are provided. Part of the rolling balls are displaced out of the annular groove.

[0005] The present invention is further configured such that: the telescopic column includes a column rod and a spring sleeved on the column rod, one end of the column rod is fixed to the upper end face of the positioning seat, and the other end slides through the bracket; one end of the spring abuts against the positioning seat, and the other end abuts against the bracket.

[0006] The present invention is further configured such that: the telescopic columns are distributed on both sides and the front end of the positioning seat; the bracket is provided with stepped grooves corresponding to the telescopic columns on both sides of the positioning seat; a through-hole for the column rod to pass through is provided in the stepped groove; and the bracket is provided with an adjustment frame corresponding to the telescopic column at the front end of the positioning seat.

[0007] The present invention is further configured such that: the adjustment frame includes a base frame with a through-hole and adjustment grooves located on both sides of the base frame, and fixing bolts are installed in the adjustment grooves to fix the adjustment frame to the support.

[0008] By adopting the above technical solution and adding a positioning device, the positioning device can not only move with the cutting blade during operation, but also press the soft fabric flat, making the cutting surface smooth and improving the quality of the cutting process. At the same time, this structure has the advantages of being simple, compact, and having low production costs. Attached Figure Description

Detailed Implementation

[0015] Reference Figures 1 to 5 The embodiments of this utility model will be further described below.

[0016] A shoe material cutting device includes a cutting workbench 1 and a cutting device 2 located above the cutting workbench 1. The cutting device 2 includes a support 3 and a cylindrical cutting blade 4. The support 3 is provided with a positioning device 5. The positioning device 5 includes an annular positioning seat 50 with a circular opening 500 in the middle. The cutting blade 4 passes through the circular opening 500. The upper end face of the positioning seat 50 is provided with at least three telescopic columns 51. The telescopic columns 51 are slidably fitted onto the support 3. The lower end face is provided with an annular groove 501. The annular groove 501 is provided with a plurality of rolling balls 502. Part of the rolling balls 502 are displaced out of the annular groove 501.

[0017] The telescopic column 51 includes a column rod 510 and a spring 511 sleeved on the column rod 510. One end of the column rod 510 is fixed to the upper end face of the positioning seat 50, and the other end slides through the bracket 3. One end of the spring 511 abuts against the positioning seat 50, and the other end abuts against the bracket 3.

[0018] The telescopic columns 51 are distributed on both sides and the front end of the positioning seat 50. The bracket 3 is provided with stepped grooves 30 corresponding to the telescopic columns 51 on both sides of the positioning seat 50. A through-hole 31 for the column rod 510 to pass through is provided in the stepped groove 30. The bracket 3 is provided with an adjustment frame 6 corresponding to the telescopic column 51 at the front end of the positioning seat 50.

[0019] The adjustment frame 6 includes a base frame 61 with a through opening 60 and adjustment grooves 62 located on both sides of the base frame 61. The adjustment grooves 62 are fitted with fixing bolts 63, which fix the adjustment frame 6 to the bracket 3.

[0020] Working principle: When the cutting blade 4 cuts the leather fabric, the positioning seat 50 on the positioning device 5 also moves to the surface of the leather fabric, pressing the fabric down. Under pressure, the positioning seat 50 adjusts its height by sliding along the through-holes 31 and 60 via the telescopic column 51, allowing it to adjust automatically according to actual usage. The positioning seat 50 assists the cutting blade 4 in the cutting process, keeping the fabric flat. Simultaneously, the ball bearings 502 on the positioning device 5 move with the cutting blade 4, positioning the fabric without obstructing its operation.

[0021] After loosening the fixing bolt 63, the adjusting frame 6 slides up and down along the fixing bolt 63 via the adjusting slide 62, which can slightly adjust the position of the telescopic column 51, thereby slightly adjusting the position of the positioning seat 50. After the adjustment is completed, the fixing bolt 63 is tightened to fix the height position of the adjusting frame 6.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
