DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1: Figure 1-Figure 5 The technical solution adopted by the utility model is as follows: a cloth cutting device of a shaping machine, which can cut fabrics such as Teslin cloth, and the cut fabrics are short waste materials, referring to Figure 5 , what is cut is the protruding and discontinuous burr parts on both sides of the cloth. It includes a cutting frame 1 and a heat sealing sheet 6. The cutting frame 1 is rotatably connected to the spacing shaft 2. The cutting frame 1 is fixedly connected to a servo motor 3. The output end of the servo motor 3 is fixedly connected to the spacing shaft 2. The servo motor 3 can drive the spacing shaft 2 to rotate in the positive and negative directions. The servo motor 3 is a prior art and will not be described in detail.

[0023] Two symmetrically arranged translation frames 5 are connected to the spacing adjustment shaft 2. The spacing adjustment shaft 2 is provided with a first external thread and a second external thread. The two translation frames 5 are threadedly connected to the spacing adjustment shaft 2 through the first external thread and the second external thread respectively. The thread directions of the first external thread and the second external thread are opposite. A limiting shaft 4 is fixedly connected to the cutting machine frame 1, and the limiting shaft 4 is slidably connected to the two translation frames 5.

[0024] When the distance adjusting shaft 2 is rotating, since the thread directions of the first external thread and the second external thread are opposite, the two translation frames 5 always move in opposite directions, so as to adjust the distance between the two cutting blades 9 to adapt to the width of the cloth to be cut.

[0025] A cutting motor 7 is fixedly connected to the translation frame 5, a cutting shaft 8 is fixedly connected to the output end of the cutting motor 7, a cutting blade 9 is fixedly connected to the cutting shaft 8, a cutting opening 10 is provided on the translation frame 5, and the upper end of the cutting blade 9 extends to the upper end surface of the translation frame 5 through the cutting opening 10. When the cloth is cut, the cloth slides relative to the top of the translation frame 5. When the cloth needs to be cut, the cutting motor 7 is controlled to control the rotation of the cutting blade 9, and the cutting blade 9 rotates to cut the cloth.

[0026] Embodiment 2: The heat sealing sheet 6 is fixedly connected to the upper end surface of the translation frame 5 through a support frame. Taking the direction of cloth feeding as the positive direction: the heat sealing sheet 6 is located above the cutting blade 9 near the front end. Specifically, the direction of cloth feeding is Figure 1 The direction of the arrow.

[0027] The translation frame 5 is rotatably connected with a cleaning shaft 12, the bottom end of which is fixedly connected with a rotating gear 13, and the cutting shaft 8 is fixedly connected with an incomplete gear 11. The incomplete gear 11 is meshed with the rotating gear 13. When the cutting blade 9 is cutting, the rotating gear 13 is driven to rotate by the incomplete gear 11. Since the cutting blade 9 rotates at a high speed when cutting the cloth, the rotation speed of the cleaning shaft 12 can be adjusted and reduced by setting a suitable gear ratio between the incomplete gear 11 and the rotating gear 13.

[0028] The upper end surface of the translation frame 5 is provided with two cleaning rods 16 for cleaning the cut cloth, and the two cleaning shafts 12 correspond to the two cleaning rods 16 one by one and are fixedly connected.

[0029] When the cleaning shaft 12 is rotated by the rotating gear 13, Figure 3 For reference, the direction of rotation of the cleaning shaft 12 is counterclockwise. Thus, when the cleaning shaft 12 rotates, the cleaning rod 16 pushes the cut waste into the collecting frame 15. And the cleaning rod 16 is attached to the upper end surface of the translation frame 5, so as to prevent the waste from being wound around the cleaning shaft 12.

[0030] The translation frame 5 is detachably connected with a collecting frame 15. The two collecting frames 15 are respectively located in the moving direction of the cloth when the two cleaning rods 16 scrape the cut cloth. The collecting frame 15 is used to collect the cut cloth, facilitate its processing, and improve the cutting efficiency of the cloth.
