Description

Technical Field

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

[0002] Currently, textile fabrics often require width-fixed cutting during production. The cutting process involves the fabric being conveyed to the cutting position via a weaving conveyor, where multiple fixed blades come into contact and cut the fabric. Since most of these blades are directly mounted on the support frame of the weaving conveyor, lacking protection and control mechanisms, it is difficult to quickly adjust the blade spacing to the required fabric width during operation. Furthermore, the blades are constantly exposed, posing a significant risk of personal injury, especially during replacement, maintenance, or when not in operation.

[0003] Based on this, the present invention designs a textile processing and cutting device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a textile processing and cutting device to solve the above-mentioned technical problems.

The positive and negative threaded walls of the positive and negative threaded screw are respectively threaded with screw sleeve blocks, and a cutting mechanism is provided at one end of the screw sleeve block.

[0006] The cutting mechanism includes a connecting arm fixedly connected to the outer wall of the lead screw sleeve block, a blade sleeve fixedly connected to the outer wall of the connecting arm, a blade slidably disposed at one end of the blade sleeve, and a push-pull electromagnet fixed at one end of the connecting arm. The push-pull end of the electromagnet is connected to the blade and is used to drive the blade to extend and retract relative to the blade sleeve.

[0007] Preferably, the cutting mechanism further includes a blade groove at one end of the blade sleeve and a sliding opening on the outer wall of the connecting arm. The sliding opening is arranged along the path of the blade groove and communicates with it. One end of the blade is slidably disposed at one end of the blade groove of the blade sleeve.

[0008] Preferably, the cutting mechanism further includes a nut connector fixedly connected to the extension end of the push-pull electromagnet spring, and a locking bolt passing through the blade and the slide, wherein the threaded end of the locking bolt is threadedly connected to the nut connector.

[0009] Preferably, a limiting rod is fixedly connected between the two mounting seats and near the positive and negative threaded rods. Two sliding sleeves are slidably connected to the outer wall of the limiting rod. The two sliding sleeves correspond to and are fixedly connected to one end of the two threaded rod sleeve blocks, respectively.

[0010] Preferably, a servo motor is fixedly connected to the outer wall of one of the mounting bases, and one end of the servo motor drive shaft is fixedly connected to one end of the positive and negative threaded rod.

[0011] Preferably, the weaving conveyor is used to transport the textile fabric to below the cutting mechanism and to bring the textile fabric into contact with the cutting edge of the inclined blade in the cutting mechanism to achieve cutting.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, when the blade is not in operation, it can be automatically retracted into the blade holder's groove by pushing and pulling the electromagnet. The blade holder effectively prevents accidental contact by the operator and improves safety.

[0023] 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 scope of protection of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a textile processing and cutting device, including: a weaving conveyor 1; two mounting seats 2 are symmetrically fixed on the top of the weaving conveyor 1, and a positive and negative threaded screw 4 is rotatably connected between the two mounting seats 2. The positive and negative threaded walls of the positive and negative threaded screw 4 are respectively threaded with screw sleeve blocks 6, and a cutting mechanism is provided at one end of the screw sleeve block 6.

[0025] The cutting mechanism includes a connecting arm 8 fixedly connected to the outer wall of the lead screw sleeve block 6, a blade sleeve 9 fixedly connected to the outer wall of the connecting arm 8, a blade 11 slidably disposed at one end of the blade sleeve 9, and a push-pull electromagnet 13 fixedly connected to one end of the connecting arm 8. The push-pull end of the push-pull electromagnet 13 is connected to the blade 11 and is used to drive the blade 11 to perform telescopic movement relative to the blade sleeve 9.

[0026] The positive and negative threaded screw 4 is a screw with positive and negative threaded sections. After the two screw sleeves 6 are threadedly connected, they can be pushed to move synchronously in opposite directions or in opposite directions when rotated. Each screw sleeve 6 drives a cutting mechanism to move, so as to quickly adjust to accommodate more fabric widths. In the cutting mechanism, the blade 11 is driven by the push-pull electromagnet 13 and extends and retracts in the blade sleeve 9, so that the blade 11 can automatically retract, improving safety.

[0027] More preferably, the cutting mechanism also includes a blade groove 10 opened at one end of the blade sleeve 9 and a sliding opening 12 opened on the outer wall of the connecting arm 8. The sliding opening 12 is arranged along the opening path of the blade groove 10 and is connected to it. One end of the blade 11 is slidably disposed at one end of the blade groove 10 of the blade sleeve 9.

[0028] An open groove 10 is provided on the outer wall of the blade sleeve 9, and a sliding opening 12 is provided on the connecting arm 8. An auxiliary push-pull electromagnet 13 drives the blade 11 to move linearly and extend along the groove 10. One end of the groove 10 of the blade sleeve 9 is open to allow the blade 11 to extend and retract, so that the blade 11 extends out of the groove 10 at a preset angle to achieve stable guidance.

[0029] More preferably, the cutting mechanism also includes a nut connector 14 fixedly connected to the spring extension end of the push-pull electromagnet 13, and a locking bolt 15 that penetrates the blade 11 and the slide 12, with the threaded end of the locking bolt 15 threadedly connected to the nut connector 14.

[0030] The locking bolt 15 passes through the blade 11 and the slide 12. The threaded end is connected to the nut connector 14, and the screw end abuts against the blade 11. The blade 11 can be moved by pushing and pulling the spring extension end of the electromagnet 13. Disassembly is simple and blade replacement is convenient.

[0031] More preferably, a limiting rod 3 is fixedly connected between the two mounting bases 2 and close to the positive and negative threaded rods 4. Two sliding sleeves 7 are slidably connected to the outer wall of the limiting rod 3. The two sliding sleeves 7 correspond to one end of the two threaded rod sleeves 6 and are fixedly connected.

[0032] A limiting rod 3 is arranged between the two mounting bases 2. When the lead screw sleeve block 6 moves laterally, the connected sliding sleeve 7 slides on the limiting rod 3, which provides guidance and constraint. A wire loop is provided at the bottom of the sliding sleeve 7 for the external control cable of the push-pull electromagnet 13.

[0033] More preferably, a servo motor 5 is fixedly connected to the outer wall of a mounting base 2, and one end of the drive shaft of the servo motor 5 is fixedly connected to one end of the positive and negative threaded rod 4;

[0034] A servo motor 5 is mounted on a mounting base 2 to drive the forward and reverse threaded screw 4 to rotate forward or in reverse.

[0035] More preferably, the weaving conveyor 1 is used to convey the textile fabric to the area below the cutting mechanism and to bring the textile fabric into contact with the cutting edge of the inclined blade 11 in the cutting mechanism to achieve cutting;

[0036] The fabric conveyor 1 is a common fabric conveying equipment that can send the fabric to the bottom of the cutting mechanism. The blade 11 in the cutting mechanism is set in an inclined position. The inclined blade 11 is conducive to improving cutting efficiency and cut surface neatness. Automatic feeding and automatic cutting are seamlessly connected.

[0037] One specific application of this embodiment is as follows: Before the cutting process, the servo motor 5 can be started to drive the positive and negative threaded screws to rotate in the forward or reverse direction, so that the two screw sleeves 6 move closer or further apart under the thread drive. When the cutting mechanism moves to the designated position, the push-pull electromagnet 13 is energized and started. Its spring push-pull end retracts and drives the blade 11 to extend along the blade groove 10 port of the blade sleeve 9. Then the weaving conveyor 1 transports the textile fabric to be cut to the bottom of the cutting mechanism and makes the textile fabric contact the blade 11 of the connecting arm 8. As the textile fabric moves, the blade 11 gradually cuts the passing textile fabric.

[0038] After the cutting is completed, the push-pull electromagnet 13 is de-energized. Through the rebound action of the spring, the spring push-pull end drives the entire blade 11 back into the blade sleeve 9, so that the blade edge is no longer exposed and thus improves safety.
