[0001] This utility model relates to the field of garment processing technology, specifically, a garment fabric cutting device. Background Technology

[0002] A fabric cutting machine is a piece of equipment used in industrial production, mainly for cutting large-format fabrics into multiple narrow fabric pieces according to a predetermined width. Existing technology includes a Chinese utility model patent (CN220579668U) that discloses a fabric cutting machine for garment production. This machine includes a machine body with a support assembly on its top. Multiple cutting blade assemblies are mounted on the support assembly, all positioned above the machine body along the fabric's movement direction. Its advantages are: the position of the cutting blade assemblies on the lead screw can be adjusted according to the fabric width cutting requirements; as the fabric moves on the machine body, the blades within the multiple cutting blade assemblies can quickly cut the wide fabric into multiple narrow fabric pieces, thus improving garment manufacturing efficiency. However, the drawback of this solution is that each time a new roll of fabric needs to be laid, the support components used to support the cutter need to be disassembled and adjusted to facilitate the laying of the fabric between the frame and the cutter. After the fabric is laid, the position of the support components needs to be readjusted to adjust the relative position of the cutter and the fabric. The accuracy of the relative position of the cutter and the fabric determines the cutting quality. Therefore, each adjustment of the support components is time-consuming and cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a garment fabric cutting device that solves the problem that existing cutting devices require adjusting the cutter every time a roll of fabric is changed, which is cumbersome, time-consuming, and inefficient.

Detailed Implementation

[0024] 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.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0026] This embodiment provides a garment fabric cutting device, as shown in Figures 1, 3, 4, and 5. It includes a device frame on which an unwinding roller, a fabric cutting section, and multiple take-up rollers are sequentially installed. The fabric is released from the unwinding roller, divided into multiple strips by the fabric cutting section, and then taken up one by one by the multiple take-up rollers. Since the device frame, take-up rollers, and unwinding rollers are all existing technologies, and this utility model does not require protection for them, they are not shown in the accompanying drawings.

[0027] The fabric dividing section includes a mounting frame 20 and a plurality of dividers 10 mounted thereon; each divider 10 includes a mounting frame, a pressing unit, a switching unit, and a dividing blade 105; the switching unit includes a switching rod 107, a limiting rod 108, a blade holder 104, a second spring 111, and a pad 114; the mounting frame includes a base 101 and a limiting frame mounted thereon; the switching rod 107 is rotatably connected to the base 101, and a pressing ear is provided on each side of the switching rod 107; the limiting rod 108 is fixedly mounted on the base 101 to limit the pressing ear of the switching rod 107; the dividing blade 105 is mounted on the blade holder 104; the pad 114 is slidably connected to the blade holder 104; a second spring 111 is provided between the blade holder 104 and the pad 114; the switching rod 107 is movably connected to the blade holder 104; and the blade holder 104 is pressed against the limiting frame.

[0028] Before operation, preliminary adjustments are performed by pressing the higher pressing lug of the switching lever 107 using the pressing unit. The switching lever 107 is then subjected to a rotational force, causing it to compress the pad 114. The pad 114, in turn, compresses the second spring 111. At this point, the angle between the switching lever 107 and the tool holder 104 begins to increase until it reaches 180 degrees. At this point, the switching lever 107 and the tool holder 104 are collinear, and the second spring 111 is compressed to its maximum extent. As the switching lever 107 rotates further, the angle exceeds 180 degrees, and the second spring 111 releases its elasticity, causing the tool holder 104 to slide from the side of the limiting frame away from the equipment frame to the side closer to the equipment frame, thus changing from the state shown in Figure 5 to the state shown in Figure 3. Afterwards, the height of the configuration frame 20 on the equipment frame is adjusted to ensure... The dividing blade 105 is designed to effectively divide the fabric. Then, the mounting frame 20 is fully secured, and the switching lever 107 is pressed once more, returning the dividing blade 105 to the position shown in Figure 5. At this point, the unwinding roller is activated to release the fabric, which is then pulled through the equipment frame and the divider 10 until it is wound up by the take-up roller. The switching lever 107 is pressed again, returning the dividing blade 105 to the position shown in Figure 3, where it rests on the fabric, beginning the dividing process. The dividing operation then officially begins. Once one roll of fabric is divided, there is no need to adjust the mounting frame 20. Simply press the switching lever 107 to return the dividing blade 105 to the position shown in Figure 5, and a new roll of fabric can be laid out. Then, pressing the switching lever 107 again returns the dividing blade 105 to the position shown in Figure 3, starting a new round of dividing operations.

[0029] With the above setup, after each roll of fabric is divided, the worker only needs to press the switching lever 107 to move the dividing blade 105 away from the dividing station. At this point, the worker can directly begin laying the new roll of fabric. Then, pressing the switching lever 107 again returns the dividing blade 105 to the dividing station to continue working. This eliminates the need for frequent disassembly and reassembly of the configuration frame 20, saving considerable time and improving work efficiency. Example 2:

[0030] This embodiment further expands the mounting frame based on the above embodiment, as shown in Figures 3-5. The limiting frame includes a movable frame 109 and a fixed frame 110. The fixed frame 110 is fixedly connected to the base 101, and the movable frame 109 is rotatably connected to the base 101. A torsion spring 113 is installed at the connection between the movable frame 109 and the base 101.

[0031] The limiting frame is set up in two parts. When the dividing blade 105 needs to be replaced or repaired, the dividing blade 105 is first made to the state shown in Figure 5. At this time, under the force of the torsion spring 113, the movable frame 109 limits the blade holder 104. The operator overcomes the elastic force of the torsion spring 113 and pries the movable frame 109 to separate the movable frame 109 from the fixed frame 110. At this time, the blade holder 104 will slide out under the elastic force of the second spring 111. Then the operator can remove the blade holder 104 and replace the dividing blade 105 on the blade holder 104. Then the blade holder 104 is reinserted into the switching rod 107. The movable frame 109 returns to the state of being in contact with the fixed frame 110 under the elastic force of the torsion spring 113. It is not necessary to remove the entire switching unit for replacement, which facilitates the maintenance and replacement of the dividing blade 105.

[0032] Furthermore, a protective cover 112 is installed on the movable frame 109, which is used to cover the cutting blade 105. By enclosing the cutting blade 105 with the protective cover 112, the cutting blade 105 can be prevented from accidentally injuring workers and causing safety accidents, thus improving safety.

[0033] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again. Embodiment 3:

[0034] This embodiment further expands the pressing unit based on the above embodiment, as shown in Figures 3, 4, 6, and 7. The pressing unit includes a pressing rod 102, a first spring 103, an adjusting shaft 115, a pressing strip 106, and an adjusting group. The adjusting shaft 115 is mounted on the base 101, and the pressing rod 102 is mounted on the adjusting shaft 115. The first spring 103 is provided between the base 101 and the pressing rod 102. The pressing strip 106 is mounted on the adjusting shaft 115 and is used to press the pressing ear of the switching rod 107. The adjusting group is used to automatically change the orientation of the pressing strip 106 to ensure that it only presses the higher pressing ear on the switching rod 107.

[0035] Furthermore, the adjustment assembly includes a pin 116 and a third spring 117; the pin 116 is slidably connected to the base 101, and the third spring 117 is provided between the pin 116 and the base 101; the adjustment shaft 115 is provided with two vertical slide grooves 118 and a spiral slide groove 119, the vertical slide grooves 118 and the spiral slide grooves 119 are alternately arranged and completely connected to form a closed loop, and guide platforms 120 are provided on both the vertical slide grooves 118 and the spiral slide grooves 119, and the pin 116 slides in the vertical slide grooves 118 and the spiral slide grooves 119.

[0036] The specific working principle of the pressing unit is as follows: When the operator presses the pressing rod 102, causing the adjusting shaft 115 to move downwards, the first spring 103 is compressed, and at the same time, the pin 116 begins to slide upwards relative to the vertical slide groove 118. When the pin 116 slides to the guide platform 120 on the vertical slide groove 118, the third spring 117 is compressed; then the pin 116 slides to the spiral slide groove 119, at which time the third spring 117 causes the pin 116 to pop out and reset; correspondingly, the pressing bar 106 presses one pressing ear of the switching rod 107. When the pin 116 slides to the spiral slide groove 119, the dividing blade 105 has moved from one side of the limiting frame to the other side; then the operator releases the pressing rod 102, at which time the first spring 103 is compressed. A spring 103 drives the pressing rod 102 to move upward and reset. Since the guide table 120 blocks the pin 116 from sliding into the vertical slide groove 118, the pin 116 begins to slide on the spiral slide groove 119. At this time, the adjusting shaft 115 not only moves upward but also rotates half a turn until the pin 116 passes the guide table 120 on the spiral slide groove 119 and returns to the bottom of another vertical slide groove 118. At this time, the pressing rod 102 is fully reset, the adjusting shaft 115 has rotated half a turn compared to the initial state, and the pin 116 has slid from one vertical slide groove 118 to another vertical slide groove 118. The height of the two pressing ears on the switching rod 107 also changes. When pressing the rod 102 in the same way, the principle is the same as the above steps.

[0037] The above settings allow staff to press both pressing ears of the switch lever 107 directly with a single button, eliminating the need to search for which ear is the higher one, thus reducing operational difficulty and improving adjustment efficiency.

[0038] The other parts of this embodiment are the same as those in the above embodiments, and will not be repeated here. Embodiment 4:

[0039] This embodiment further expands the configuration frame 20 based on the above embodiment, as shown in Figures 2 and 4. The configuration frame 20 includes a first support shaft 204, a second support shaft 206, and two symmetrically arranged configuration frame bodies 201. Both ends of the first support shaft 204 and the second support shaft 206 are mounted on the configuration frame bodies 201. The first support shaft 204 is provided with a locking surface 205. The first support shaft 204 and the second support shaft 206 are inserted into the base 101. Bolts 207 are installed on the base 101. The bolts 207 cooperate with the locking surface 205 to limit the position of the divider 10.

[0040] The first support shaft 204 and the second support shaft 206 are used to limit the movement of the divider 10, so that it can only slide laterally. The bolt 207 is tightened and pressed on the locking surface 205, so that the divider 10 is completely fixed. Therefore, when adjusting the distance between the dividers 10, the bolt 207 can be loosened first, and then tightened after adjustment. Only one bolt 207 needs to be tightened to fix one divider 10, which is highly efficient.

[0041] Furthermore, the configuration frame 20 also includes a synchronous pressure rod 202, which is slidably connected to the configuration frame body 201, and a fourth spring 203 is provided between the synchronous pressure rod 202 and the configuration frame body 201.

[0042] When the operator presses the synchronous pressure rod 202, the fourth spring 203 is compressed. At this time, the synchronous pressure rod 202 will press all the pressing rods 102, so that all the pressing rods 102 can be adjusted in a unified manner without pressing them one by one, which further improves the work efficiency. At the same time, this method ensures that the dividing blades 105 of multiple dividers 10 are in the same position, preventing some dividing blades 105 from working while others are not.

[0043] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
