Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of automatic fabric rolling machine, and specifically relates to a cutting structure for an automatic fabric rolling machine. Background Technology
[0002] In the textile industry, automatic fabric winding machines are crucial equipment for efficient fabric winding and finishing. Currently, the fabric pressing function of automatic fabric winding machines mostly uses point pressing. This point pressing method results in uneven pressure distribution during the cutting process. When cutting fabric, uneven force leads to displacement, wrinkles, and other problems, severely affecting cutting accuracy and quality. This is especially true when cutting thin and easily deformable fabrics, where the drawbacks of point pressing are amplified, resulting in uneven edges that fail to meet production requirements. Furthermore, in terms of cutting methods, existing automatic fabric winding machines mostly use linear track cutting devices. In practice, these track-type cutting devices are mostly operated in a semi-automatic manual mode. Operators manually control the cutting components to move along the track to complete the cutting work. This process is not only slow, but existing track-type cutting devices can only perform unidirectional cutting. After each cut, the fabric cutting device needs to be reset to the starting position before the next cut can be made. This greatly increases the time cost of cutting and reduces production efficiency. Especially in large-scale fabric cutting operations, this inefficient cutting method will seriously restrict the production schedule.
[0003] In order to overcome the above-mentioned defects of the existing automatic fabric rolling machine cutting structure, this utility model proposes a cutting structure for an automatic fabric rolling machine, which ensures uniform pressing force and realizes bidirectional cutting, thereby effectively improving cutting efficiency. Utility Model Content
[0004] To achieve the above objectives, this utility model provides the following technical solution: a cutting structure for an automatic fabric rolling machine, comprising a frame, with tabletops fixed on both sides of the top of the frame, a cutting slit between the two tabletops, a support fixed on the top of the tabletops, and pressing cylinders evenly fixed on the bottom of the support. A pressing rod is fixed to the output end of the pressing cylinder, and the pressing rod is arranged parallel to the tabletops. A housing is fixed on the top of one of the support, and slides are slidably connected to both ends of the top of the housing. A moving mechanism is provided between the slides and the housing. A support is fixed on one side of the slide, and a lifting cylinder is fixed on the top of the support. A fixing frame is fixed to the output end of the lifting cylinder, and the fixing frame and the support are slidably connected. A cutting saw is installed at the bottom of the fixing frame.
[0005] As a preferred embodiment of this utility model, the saw blade and the cutting kerf of the cutting saw are arranged along the same line.
[0006] As a preferred embodiment of this utility model, the moving mechanism includes screws, which are respectively installed at both ends inside the housing, and each screw has a drive mechanism installed at one end. The screw body is threadedly connected to a nut seat, and the slide is fixed to the top of the nut seat.
[0007] As a preferred embodiment of this utility model, the screw rods at both ends inside the housing have opposite thread directions, and the corresponding threads inside the nut seat are also opposite.
[0008] In a preferred embodiment of this invention, the housing and the slide table, as well as the fixed frame and the support, are slidably connected by linear guide rails and sliders.
[0009] In a preferred embodiment of this invention, the countertop is entirely made of stainless steel. Compared with the prior art, the advantages of this invention are:
[0010] (1) By installing a pressing rod parallel to the table surface, this utility model can evenly press the two sides of the fabric cutting point, ensuring that the fabric is subjected to uniform force during the cutting process, effectively avoiding fabric displacement and wrinkles, greatly improving the cutting accuracy and quality, and meeting production requirements.
[0011] (2) This utility model achieves bidirectional cutting by setting slides at both ends of the top of the machine casing and using a moving mechanism to drive the slides to move. This allows the two cutting saws to move towards or away from each other. This bidirectional cutting method, as well as the method of directly lifting the cutting saws with a lifting cylinder after cutting, enables the cutting saws to pass through the fabric smoothly without returning to the starting point, greatly shortening the cutting time and improving the cutting efficiency. Especially in large-scale fabric cutting operations, it can significantly speed up the production progress and improve the overall production efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example
[0019] Please see Figure 1-3 This utility model provides the following technical solution: a cutting structure for an automatic fabric rolling machine, including a frame 1, with tabletops 2 fixed on both sides of the top of the frame 1, a cutting slit 3 between the two tabletops 2, a support 4 fixed on the top of the tabletops 2, and pressing cylinders 5 evenly fixed at the bottom of the support 4. A pressing rod 6 is fixed at the output end of the pressing cylinder 5 and is arranged parallel to the tabletops 2. A housing 7 is fixed on the top of one support 4, and slides 8 are slidably connected to both ends of the top of the housing 7. A moving mechanism is provided between the slides 8 and the housing 7. A support 9 is fixed on one side of the slides 8, and a lifting cylinder 11 is fixed on the top of the support 9. A fixing frame 10 is fixed at the output end of the lifting cylinder 11. The fixing frame 10 and the support 9 are slidably connected. A cutting saw 12 is installed at the bottom of the fixing frame 10, and the saw blade of the cutting saw 12 and the cutting slit 3 are arranged collinearly.
[0020] To facilitate the movement of the screws in opposite directions and avoid collisions with the cutting saw 12, in this embodiment, as a preferred technical solution of the present invention, the moving mechanism includes screws 13. The screws 13 are respectively installed at both ends inside the housing 7, and a drive mechanism 14 is installed at one end of each screw 13. The screw 13 is threadedly connected to a nut seat 15, and the slide table 8 is fixed to the top of the nut seat 15. The screws 13 at both ends inside the housing 7 have opposite thread directions, and the corresponding threads inside the nut seat 15 are also opposite.
[0021] To ensure stability during movement, in this embodiment, as a preferred technical solution of the present invention, the housing 7 and the slide table 8, as well as the fixed frame 10 and the support 9, are slidably connected by linear guide rails and sliders.
[0022] In order to reduce the friction between the fabric and the countertop 2 and avoid scratching the fabric, in this embodiment, as a preferred technical solution of the present invention, the countertop 2 is made entirely of stainless steel.
[0023] In summary, based on the above-described technical solution of this utility model, the following is the usage process of the cutting structure for the automatic fabric rolling machine:
[0024] First, place the fabric to be cut flat on the table 2, and let the fabric pass through the bottom of the bracket 4;
[0025] Start the clamping cylinder 5. The output end of the clamping cylinder 5 pushes the pressing rod 6 downward. Since the pressing rod 6 is set parallel to the table surface 2 and the clamping cylinders 5 are evenly distributed at the bottom of the bracket 4, the pressing rod 6 can evenly press the two sides of the fabric cutting point, avoiding displacement and wrinkles of the fabric due to the cutting force of the cutting saw 12 during the cutting process, and ensuring cutting accuracy.
[0026] Start the lifting cylinder 11. The output end of the lifting cylinder 11 drives the fixed frame 10 to slide vertically downward on the support 9 through the linear guide rail and the slider, thereby causing the cutting saw 12 installed at the bottom of the fixed frame 10 to descend to the appropriate cutting position.
[0027] Start the two drive mechanisms 14 to drive the screw 13 to rotate. Since the threads of the screws 13 at both ends inside the housing 7 are opposite, and the threads inside the corresponding nut seats 15 are also opposite, the two nut seats 15 will drive the slide table 8 to move in opposite directions on the top of the housing 7 via the linear guide rail and the slider.
[0028] When the slide table 8 moves, it drives the cutting saw 12 to move via the support 9, lifting cylinder 11, and fixed frame 10, achieving bidirectional cutting and improving cutting efficiency. However, due to the inconsistent path lengths of the screws 13 at both ends inside the housing 7, the nut seat 15 on the relatively shorter screw 13 rotates in the opposite direction corresponding to the drive mechanism 14 after reaching the end point, causing the nut seat 15 on the shorter screw 13 to return to the starting point; while the nut seat 15 on the longer screw 13 continues to move until the cutting saw 12 completes the fabric cutting. The inconsistent path lengths of the screws 13 can prevent the cutting saws 12 on both sides from colliding with each other when cutting in opposite directions, thus avoiding any impact. The saw blade of the cutting saw 12 moves within the cutting kerf 3 to cut the fabric. During the cutting process, the cutting saw 12 continues to work until the fabric cutting is completed.
[0029] After the fabric is cut, start the lifting cylinder 11, which will cause the output end of the lifting cylinder 11 to drive the fixed frame 10 and the cutting saw 12 to rise and detach from the fabric. Then start the drive mechanism 14, which will cause the slide table 8 to drive the cutting saw 12 back to the initial position. Then close the clamping cylinder 5, and the pressing rod 6 will rise to release the pressure on the fabric.
[0030] Finally, it should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
