Description

Technical Field

[0001] The utility model relates to the technical field of cloth cutting machines, in particular to an alignment structure for a cloth cutting machine. Background Art

[0002] In the textile industry, cloth cutting is an important link in the production process. Most traditional cloth cutting machines rely on manual operation to ensure the alignment state of the cloth before cutting. In order to improve the cutting efficiency, an alignment structure has emerged, but the existing alignment structure has certain limitations in use.

[0003] For example, in the Chinese patent with the publication number "CN 218968399 U", a precisely controlled cloth feeding machine is disclosed, including a roller mounting plate, a roller assembly, a cloth edge detection assembly, an action control device, etc. Although this device can perform alignment operations on the cloth, when aligning the cloth, the distance of the alignment structure cannot be adjusted. Therefore, when aligning a cloth with a smaller width, the cloth is prone to shift during movement, reducing the alignment efficiency of the device for the cloth and narrowing the scope of use of the device. Summary of the Utility Model

[0004] The utility model provides an alignment structure for a cloth cutting machine to solve the problem that the existing device is prone to shift when aligning a cloth with a smaller width.

[0005] To achieve the above object, the utility model provides the following technical solution: An alignment structure for a cloth cutting machine, including a guiding member. The guiding member includes a guiding part and two symmetrically arranged guiding parts, and a moving cavity for guiding the movement of the cloth is formed between the two guiding parts. The guiding part includes a substrate, and a through installation groove is opened on the substrate. A lead screw is rotatably connected inside the installation groove, and the bottoms of the two guiding parts are both sleeved on the lead screw. By rotating the lead screw, the two guiding parts approach or separate from each other.

[0006] Preferably, a first motor is fixedly connected to the substrate, and the output end of the first motor is connected to the lead screw.

[0007] Preferably, the guiding part includes a base frame. On one side of the two base frames facing each other, a side groove is recessed. Two positioning rollers are symmetrically and rotatably connected inside the side groove. The moving cavity is formed between the four positioning rollers. A second motor is fixedly connected to the base frame, and the output end of the second motor is connected to one of the positioning rollers.

[0008] Preferably, a moving plate is fixedly connected to the bottom of the base frame. The moving plate is sleeved on the lead screw. Opposite thread grooves are opened on the two moving plates, and both thread grooves match the lead screw.

[0009] Preferably, two second limiting members for abutting against the bottom of the fabric are symmetrically and fixedly connected to the top of the guiding member. The installation groove is located between the two second limiting members. The second limiting member includes a second mounting frame, and a second limiting roller is rotatably connected to the top of the second mounting frame.

[0010] Preferably, a first limiting member for abutting against the top of the fabric is fixedly connected above the substrate. The first limiting member is located above the second limiting roller. The first limiting member includes a top frame. Two first electric push rods are symmetrically and fixedly connected to the top of the top frame. The telescopic ends of the two first electric push rods extend below the top frame, and a first mounting frame is fixedly connected between the telescopic ends of the two first electric push rods. A first limiting roller is rotatably connected to the bottom of the first mounting frame.

[0011] In the above technical solution, the technical effects and advantages provided by the present invention are as follows:

[0012] (1) By rotating the lead screw inside the installation groove, the two guiding parts move in the installation groove, thereby adjusting the distance between the two guiding parts, enabling the device to be adjusted according to the width of the fabric, making it easier for the fabric not to shift during movement, improving the centering efficiency of the device for the fabric, and expanding the application range of the device;

[0013] (2) When the device centers the fabric through the positioning roller, the second positioning roller supports the bottom of the fabric, and the first electric push rod drives the first mounting frame to move, so that the first mounting frame drives the first limiting roller to abut against the top of the fabric, making the fabric move more stably during centering and avoiding accidental loosening during the centering process of the fabric, further improving the centering efficiency of the device for the fabric.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 - 6 shown, a centering structure of a cloth cutting machine includes a guide member 1. The guide member 1 includes a guiding part and two symmetrically arranged guiding parts, and a moving cavity for guiding the movement of the cloth is formed between the two guiding parts. The guiding part includes a substrate 11. A through installation groove 13 is opened on the substrate 11. A lead screw 14 is rotatably connected inside the installation groove 13. The bottoms of the two guiding parts are both sleeved on the lead screw 14. By rotating the lead screw 14, the two guiding parts approach or move away from each other;

[0024] A first motor 12 is fixedly connected to the substrate 11, and the output end of the first motor 12 is connected to the lead screw 14.

[0025] Through the above technical solution, before cutting the cloth, the first motor 12 is driven to rotate the lead screw 14 in the installation groove 13 on the substrate 11, so that the two guiding parts move along the lead screw 14, and then the distance between the two guiding parts is adjusted. After the distance between the two guiding parts is adjusted, the cloth to be cut is passed through the two guiding parts, and then the cloth passing through the two guiding parts is conveyed to a cloth cutting machine (not shown in the figure). The cloth is centered by the two guiding parts, so that the cloth is always in the middle position, making it convenient for the subsequent cloth cutting machine to perform cutting.

[0026] Specifically, in one embodiment, regarding the above guiding part, as Figures 1 - 4As shown, the guiding part includes a base frame 15. On both opposite sides of the two base frames 15, recesses are formed to form side grooves 17. Inside the side grooves 17, two positioning rollers 18 are symmetrically and rotatably connected. A moving cavity is formed between the four positioning rollers 18. A second motor 16 is fixedly connected to the base frame 15, and the output end of the second motor 16 is connected to one of the positioning rollers 18.

[0027] In this embodiment, when the fabric passes between the two base frames 15, it is supported by the side grooves 17 on the base frame 15. Then the fabric is passed between the four positioning rollers 18. By operating the second motor 16, the second motor 16 drives the positioning rollers 18 to rotate in the side grooves 17, guiding the fabric to move through the positioning rollers 18 and centering the fabric.

[0028] In addition, in this utility model, regarding how the base frame 15 is connected to the lead screw 14, a moving plate 19 is fixedly connected to the bottom of the base frame 15. The moving plate 19 is sleeved on the lead screw 14. Opposite thread grooves are formed on the two moving plates 19, and both thread grooves match the lead screw 14.

[0029] In this embodiment, when it is necessary to drive the two base frames 15 to move relative to each other, the base plate 11 supports the first motor 12. The first motor 12 drives the lead screw 14 to rotate in the installation groove 13. Through the cooperation of the opposite thread grooves on the moving plates 19, the two moving plates 19 move relative to each other, thereby adjusting the distance between the two moving plates 19 to the distance required by the operator, and then adjusting the distance between the four positioning rollers 18. After the distance between the four positioning rollers 18 is adjusted, the fabric is guided and centered by the positioning rollers 18.

[0030] Moreover, in this utility model, to make the fabric transportation smoother, as Figures 1 - 3 and Figure 5 shown, two second limiting members 3 for abutting against the bottom of the fabric are symmetrically and fixedly connected to the top of the guiding member 1. The installation groove 13 is between the two second limiting members 3, and the second limiting member 3 includes a second mounting frame 32. A second limiting roller 31 is rotatably connected to the top of the second mounting frame 32;

[0031] Above the base plate 11, a first limiting member 2 for abutting against the top of the fabric is fixedly connected. The first limiting member 2 is above the second limiting roller 31, and the first limiting member 2 includes a top frame 21. Two first electric push rods 22 are symmetrically and fixedly connected to the top of the top frame 21. The telescopic ends of the two first electric push rods 22 extend below the top frame 21, and a first mounting frame 23 is fixedly connected between the telescopic ends of the two first electric push rods 22. A first limiting roller 24 is rotatably connected to the bottom of the first mounting frame 23.

[0032] In this embodiment, when centering the fabric by means of four positioning rollers 18, the second limiting roller 31 is supported by the second mounting bracket 32, the bottom of the fabric is supported by the second limiting roller 31, the first electric push rod 22 is supported by the top bracket 21, the first mounting bracket 23 is driven to move by the first electric push rod 22, the first mounting bracket 23 drives the first limiting roller 24 to move, and the first limiting roller 24 contacts the top of the fabric, so that the fabric moves more smoothly and the stability of fabric centering is improved.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
