Description

Technical Field

[0001] This utility model relates to the field of leather cutting technology, and in particular to a scraping device for producing handbags. Background Technology

[0002] With the innovative development of the leather industry, leather products have gradually encompassed major sectors such as leather goods, footwear, leather tanning, and related products, leading to a gradual increase in people's demand for and quality of leather products. To meet the demand for leather products, along with the restructuring of the leather industry, equipment that optimizes leather production processes, such as leather spraying machines, leather ironing machines, leather buffing machines, and leather sewing machines, has emerged. Among these, the leather peeling machine is one such example.

[0003] In existing peeling machines, the presser foot is positioned directly above the cutting edge. When cutting leather, the presser foot presses the leather onto the feed roller, which then guides the leather into the cutting blade to complete the cutting. However, since the pressure applied by the presser foot to the leather is entirely manual, inexperienced workers may apply too much pressure, making it difficult to feed the leather, or apply too little pressure, resulting in incomplete cutting. Utility Model Content

[0011] This invention provides a trimming device for handbag production. It offers the following advantages: The device controls the pressure applied to the leather by the pressing block through a sliding engagement between the pressing block and the pressing foot, and a first spring between them. As the pressing foot descends, it brings the pressing block into contact with the leather surface. Further descent of the pressing foot compresses the spring. Within a certain compression range, the pressure generated by the spring can be calculated using Hooke's Law. A stop bar positioned at the top of the top rod blocks the movement of the top rod and the pressing block, controlling the compression distance of the first spring, thereby stabilizing the pressure applied to the leather by the pressing block.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A handbag production edge-trimming device includes a peeling machine 1, a presser foot 2 on the peeling machine 1, a pressure block 201 slidably mounted on the bottom of the presser foot 2, a plurality of first springs 3 between the pressure block 201 and the presser foot 2, a plurality of push rods 4 fixedly mounted on the top of the pressure block 201, and a stop rod 5 slidably mounted on the presser foot 2, with the top of the push rods 4 directly below the stop rods 5. When the peeling machine 1 is in use, the presser foot 2 is directly above the cutting edge of the peeling machine 1. When cutting the leather, the presser foot 2 presses the leather onto the feed roller, which then drives the leather into the cutting blade to complete the cutting. However, since the pressure applied by the presser foot 2 to the leather is entirely manually operated by the user of the peeling machine 1, inexperienced workers may mishandle the pressure applied by the presser foot 2. Excessive force can cause difficulties in leather conveying, while insufficient pressure from the presser foot 2 can lead to incomplete cutting. Therefore, this device controls the pressure applied by the presser foot 201 to the leather through the sliding cooperation between the presser foot 201 and the presser foot 2, and the first spring 3 between the presser foot 2 and the presser foot 201. As the presser foot 2 descends, it causes the presser foot 201 to contact the leather surface. After the presser foot 201 contacts the leather surface, the presser foot 2 continues to descend, which will cause the presser foot 201 to compress the spring. Within a certain compression range, the pressure generated by the spring can be calculated according to Hooke's Law. The stop rod 5 is set at the top of the top rod 4 to block the top rod 4, which is to control the movement stroke of the top rod 4 and the presser foot 201, that is, the compression distance of the first spring 3, so as to control the stability of the pressure applied by the presser foot 201 to the leather.

[0023] As a preferred technical solution in this embodiment, the stop bar 5 is provided with a movable groove 6, and a connecting post 7 is slidably disposed inside the movable groove 6. A turntable 8 is fixedly connected to one side of the connecting post 7. The connecting post 7 is fixedly installed on the edge of the turntable 8. When it is necessary to change the height of the stop bar 5, the connecting post 7 is rotated by rotating the turntable 8, so that the position of the connecting post 7 inside the movable groove 6 changes. At the same time, the rotation of the turntable 8 will change the height of the connecting post 7, thereby changing the height of the stop bar 5.

[0024] As a preferred embodiment, a ratchet 9 is rotatably mounted on the side wall of the presser foot 2, and a locking tongue 14 is fixedly mounted on one side of the ratchet 9. The locking tongue 14 is adapted to the tooth groove of the ratchet 9, and the ratchet 9 is fixedly connected to the turntable 8. A torsion spring 10 is provided between the ratchet 9 and the locking tongue 14 and the presser foot 2 respectively. The turntable 8 is locked by the adaptation of the ratchet 9 and the locking tongue 14. In this application, the rotation direction of the ratchet 9 is counterclockwise, and the restoring force direction of the torsion spring 10 is clockwise.

[0025] As a preferred technical solution in this embodiment, the number of tooth grooves on the ratchet 9 is fixedly related to the lifting height of the stop lever 5; by measuring the number of times the tooth grooves of the ratchet 9 disengage from the locking tongue 14, the corresponding lifting height of the stop lever 5 can be accurately determined.

[0026] As a preferred technical solution in this embodiment, a connecting post 11 is slidably installed on the locking tongue 14. The connecting post 11 is fixedly connected to the torsion spring 10. A second spring 12 is fixedly connected between the locking tongue 14 and the connecting post 11. The connecting post 11 is rotatably installed on the pressure foot 2. Through the sliding cooperation between the pressure foot 2 and the support post, the locking tongue 14 can be adapted to rotate with the ratchet 9, while the locking tongue 14 can be pulled outward to disengage from the ratchet 9, thereby unlocking the ratchet 9 and facilitating the reset of the stop bar 5.

[0027] As a preferred technical solution in this embodiment, a support frame 13 is fixedly installed on the peeling machine 1, and the presser foot 2 is fixedly installed at the bottom of the support frame 13.
