Abstract
Description
Technical Field
[0001] The utility model relates to a cutting device, in particular to a silk fabric weaving and cutting device. Background Art
[0002] The production process of silk fabrics mainly includes reeling, weaving, dyeing and finishing, and cutting. The cutting process is used to store the fabric in a fixed length for easy packaging and transportation. Existing fabric cutting equipment is divided into continuous cutting type and non-continuous cutting type, and the difference lies in whether the fabric is in a conveying state during the cutting stage. The cutting efficiency of continuous cutting equipment is much higher than the latter, but its structure is also more complex. The cutting mechanism on this type of cutting equipment is equipped with a multi-axis servo mechanism, which can drive the cutting knife to move synchronously with the fabric at the same speed. However, this will result in a larger size of the equipment, especially a longer length, resulting in a larger equipment footprint. Summary of the Invention
[0003] The utility model provides a silk fabric weaving and cutting device, which solves the problem in the prior art that the device occupies a large area.
[0004] The above technical problems of the present invention are mainly solved by the following technical solutions: A silk fabric weaving and cutting device, comprising two positioning plates, a sleeve fixedly connected between the two positioning plates, a slider slidably assembled in the sleeve, a shaft cylinder rotatably sleeved on the outside of the sleeve and a plurality of pressure rollers rotatably connected between the two positioning plates, the pressure rollers and the shaft cylinder are arranged in an external tangent to each other, the shaft cylinder is provided with cutting grooves distributed along its length, the sleeve is provided with guide grooves distributed along its length, and the slider is provided with a positioning block protruding from the guide groove. , a rotating sleeve is slidably sleeved on the outside of the sleeve, and the rotating sleeve is axially positioned relative to the positioning block. The rotating sleeve is provided with a blade seat that partially extends into the cutting groove and slides with the cutting groove. The top of the blade seat is provided with a blade extending outward. A screw rod is coaxially provided in the sleeve, and the screw rod rotates with the slider. The screw rod is installed on the two positioning plates, one of which is provided with a servo motor that drives the screw rod to rotate. The pressure roller is provided with an avoidance groove that can avoid the blade, and the distribution path of the avoidance groove is adapted to the movement path of the blade.
[0005] The present invention features a shaft for winding fabric. Rollers press against the fabric to ensure a tight fit. Fabric is drawn into the shaft by the frontmost roller and then exits the shaft by the rearmost roller. The width of the fabric is smaller than the length of the cutting slot. The blade holder is initially positioned at one end of the cutting slot, with the blade offset from the fabric, and the blade's cutting edge facing the fabric. When the fabric needs to be cut, a servo motor drives the lead screw in forward rotation, moving the slider, which in turn drives the rotating sleeve, causing the blade to begin moving toward the other end of the cutting slot, cutting the fabric. The starting point for the blade's contact with the fabric is near the first roller. During cutting, the blade's path follows a spiral curve, with the avoidance grooves on each roller aligned with this spiral path. This prevents the blade from physically colliding with the rollers. Furthermore, because the fabric is tightly held between each roller, even after the fabric is cut, it remains fixed to the shaft and unlikely to shift, ensuring a flush cut. The cut fabric then exits at the final roller. Then when the blade completes cutting, the shaft will continue to rotate. Since there is no fabric on the shaft between the end roller and the front roller, this section is the section for resetting the blade seat. The screw rotates in the opposite direction at high speed to control the reset of the blade seat.
[0006] Furthermore, the outer side of the pressure roller is covered with a rubber sleeve. The rubber sleeve is used to increase friction between the roller and the fabric, thereby improving the fixing effect on the fabric. At the same time, the rubber sleeve has an elastic deformation effect, which can reduce the installation accuracy of the equipment.
[0007] Therefore, compared with the existing technology, the present invention has the following characteristics: 1. The present invention can realize continuous cutting through the above technical scheme, that is, the fabric continues to be transported during the cutting process. At the same time, the overall structure is relatively streamlined and occupies a small area. The cutting blade is driven by only a single servo motor, which is conducive to reducing manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0016] Example 1: See Figure 1 、 Figure 2 and Figure 3 A silk fabric weaving and cutting device includes two positioning plates 10, a sleeve 20 fixedly connected between the two positioning plates, a slider 30 slidably assembled in the sleeve, a shaft cylinder 40 rotatably sleeved on the outside of the sleeve, and five pressure rollers 50 rotatably connected between the two positioning plates. Two bearings 21 are installed between the shaft cylinder and the sleeve. The pressure rollers are arranged circumferentially with the shaft cylinder. The shaft cylinder is provided with cutting grooves 41 distributed along its length. The sleeve is provided with guide grooves 22 distributed along its length. The guide grooves are provided in three rows and are distributed in a circumferential array. The slider is provided with three positioning blocks 31 protruding from the guide grooves. A rotating sleeve 60 is also slidably sleeved on the outside of the sleeve. The positioning block is provided with a card slot 32 (see Figure 6 ), the rotating sleeve is arranged in the card slot, and the rotating sleeve is provided with a blade seat 61 which partially extends into the cutting groove and slides with the cutting groove. The top of the blade seat is provided with a blade 62 extending outward, and a screw rod 70 is also coaxially provided in the sleeve. The screw rod rotates with the slider, and the screw rod is installed on two positioning plates, one of which is provided with a servo motor 71 for driving the screw rod to rotate. The pressure roller is provided with an avoidance groove 51 that can avoid the blade. The distribution path of the avoidance groove is adapted to the moving path of the blade, and the width of the avoidance groove is more than twice the width of the blade.
[0017] In this embodiment, a small gear 53 is provided at one end of the pressure roller, and a large gear 42 (see FIG. Figure 5 ), so that the pressure roller and the shaft cylinder can realize synchronous rotation. In this embodiment, 5 pressure rollers are arranged around the shaft cylinder at equal intervals, covering a range of 180° (see Figure 4The fabric is wound around the shaft, and pressure rollers press against it to ensure it adheres tightly to the shaft. The fabric is drawn into the shaft by the frontmost pressure roller and then exits the shaft by the rearmost pressure roller. The fabric width is smaller than the length of the cutting slot. The blade holder is initially positioned at one end of the cutting slot, with the blade's cutting edge facing the fabric. When the fabric needs to be cut, the servo motor drives the lead screw in forward rotation, moving the slider, which in turn drives the rotating sleeve, causing the blade to begin moving toward the other end of the cutting slot, cutting the fabric as it moves. The starting point for the blade to cut the fabric is near the first pressure roller. During the cutting process, the blade's movement path is a spiral curve, and the position of the avoidance groove on each pressure roller corresponds to this spiral curve, preventing the blade from physically colliding with the pressure rollers. Furthermore, because the fabric is tightly pressed between each pair of pressure rollers, even if the fabric is cut, it remains fixed to the shaft and is less likely to shift, ensuring a flush cut. The cut fabric flows out of the last pressure roller. Then when the blade completes cutting, the shaft will continue to rotate. Since there is no fabric on the shaft between the end roller and the front roller, this section is the section for resetting the blade seat. The screw rotates in the opposite direction at high speed to control the reset of the blade seat.
[0018] See Figure 4 The outer side of the pressure roller is covered with a rubber sleeve 52. The rubber sleeve is used to increase the friction between the rubber sleeve and the fabric, thereby improving the fixing effect on the fabric. At the same time, the rubber sleeve has an elastic deformation effect, which can reduce the installation accuracy of the equipment.
[0019] See Figure 3 The blade seat is provided with a plug-in slot, the bottom of which is provided with a magnet 64, and the blade is provided with a plug-in body 65 adapted to the plug-in slot. This makes it easy to replace the blade and is very convenient to install and disassemble.
[0020] It is obvious to those skilled in the art that the present invention can be modified in many ways, and such modifications are not considered to depart from the scope of the present invention. All such modifications obvious to those skilled in the art are intended to be included within the scope of the present claims.
