Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a cutting structure in the sewing thread processing process. Background Technology

[0002] A search revealed that application number 202323369308.7 discloses a cutting structure for sewing thread processing, including a cutting mechanism. The cutting mechanism includes a cutting frame, a hydraulic cylinder fixed to the surface of the cutting frame, one end of the hydraulic cylinder passing through the cutting frame and fixed to a movable plate, a cutting blade fixed to the bottom of the movable plate, a conveying mechanism below the cutting blade, a cleaning mechanism on the surface of the movable plate, and a winding mechanism on one side of the conveying mechanism. The conveying mechanism includes a rodless cylinder, and a pneumatic gripper is fixed to a slide table on the surface of the rodless cylinder.

[0003] The cutting structure in the sewing thread processing of this patent application uses a rodless cylinder to drive a pneumatic gripper to transport the cut sewing thread. However, in this process, the pneumatic gripper only clamps and fixes one end of the sewing thread at the cut position, lacking clamping and fixing of the other end. If the sewing thread is not taut, it affects the cutting effect of the sewing thread. Furthermore, the other end of the sewing thread is slack after cutting, affecting the collection quality of the sewing thread on the collecting roller and reducing the practicality of the device. Therefore, we propose a cutting structure for the sewing thread processing. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a cutting structure in the sewing thread processing process.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a cutting structure for sewing thread processing, including a cutting mechanism and a rodless cylinder disposed below the cutting mechanism. A winding mechanism and a guide roller assembly are respectively disposed at the front and rear ends of the rodless cylinder. A movable box is fixedly mounted on the surface slide of the rodless cylinder. A clamping mechanism is disposed on the top of the movable box. The clamping mechanism includes four mounting brackets arranged in a matrix on the top of the movable box, and two first clamping plates and two second clamping plates fixedly mounted at the ends of the four mounting brackets that are close to each other. Four limiting sliding rods are disposed at the ends of the four mounting brackets that are far apart from each other, penetrating the left and right side walls of the movable box. The movable box contains... An adjustment mechanism is provided to drive four limit slide rods to move left and right. The adjustment mechanism includes an adjustment slide plate that is slidably connected to the bottom of the inner cavity of the movable housing, two first adjustment slots that are symmetrically opened through the rear side of the top wall of the adjustment slide plate, and two second adjustment slots that are symmetrically opened through the front side of the top wall of the adjustment slide plate. Two first adjustment slide columns that are slidably connected to one end of the two limit slide rods located at the rear side are fixedly connected to the two first adjustment slots. Two second adjustment slide columns that are slidably connected to one end of the two limit slide rods located at the front side are fixedly connected to the two second adjustment slots. An adjustment electric push rod for driving the front and rear ends of the adjustment slide plate is fixedly installed on the rear wall of the movable housing.

[0006] Furthermore, the two first clamping plates are symmetrically arranged on the two mounting brackets located at the rear side, at one end close to each other.

[0007] Furthermore, the two second clamps are symmetrically arranged on the two mounting brackets located at the front side, at one end close to each other.

[0008] Furthermore, all four mounting brackets are L-shaped and arranged symmetrically.

[0009] Furthermore, four return springs are sleeved on the outer side of one end of the four limiting slide rods located on the outside of the movable box, and the two ends of the four return springs are fixedly connected to the outer wall surface of the movable box and the outer wall surface of the four mounting brackets, respectively.

[0010] Furthermore, the two first adjustment channels are L-shaped and their front ends are arranged in a parallel manner.

[0011] Furthermore, the two second adjustment channels are arranged at an angle.

[0012] Furthermore, the front ends of the two first adjustment channels correspond to the front ends of the two second adjustment channels, respectively.

[0013] Furthermore, the telescopic end of the adjusting electric push rod extends into the inner cavity of the movable housing and is fixedly installed with the rear end of the adjusting slide plate.

[0014] This utility model provides a cutting structure for sewing thread during processing. It has the following beneficial effects:

[0015] 1. This cutting structure for sewing thread processing includes a clamping mechanism and an adjusting mechanism. During use, the sewing thread is wound up by a winding mechanism, and guided by a guide roller assembly, allowing the thread to pass stably between two first clamping plates and two second clamping plates. When cutting is required, a rodless cylinder moves the moving housing to a position below the cutting mechanism. The extension and retraction end of the adjusting electric push rod drives the adjusting slide plate to slide towards the rear of the moving housing's inner cavity, forcing the two first adjusting slide columns and the two second adjusting slide columns to slide along the interior of the two first adjusting slots. The two first and second adjusting slides slide forward and move closer to each other inside the two second adjusting channels. The two first and two second adjusting slides drive the four limiting slides to move closer to each other. The four limiting slides drive the four mounting brackets to compress the four return springs, which in turn drive the two first clamping plates and the two second clamping plates to move closer to each other. This clamps and fixes the front and rear ends of the sewing thread at the cutting position, improving the stability of the sewing thread cutting position and the cutting effect of the cutting mechanism. After the sewing thread is cut, the winding mechanism is controlled to continue winding the sewing thread. The rodless cylinder drives the two first clamping plates and the two second clamping plates to move closer to each other by moving the housing. The two second clamping plates move forward synchronously with the winding mechanism's winding speed, ensuring the cut end of the sewing thread is fully wound up while taut, improving the winding quality. Controlling the extension and retraction of the electric push rod drives the adjusting slide plate forward a distance along the inner cavity of the moving housing. This causes the two second adjusting pins, guided by the two second adjusting slots, to move the two second clamping plates away from each other, releasing the clamping and fixing of the cut end of the sewing thread. When the winding mechanism is replaced and thread winding is needed, the extension and retraction of the electric push rod is again controlled to drive the adjusting slide plate further forward along the inner cavity of the moving housing. The forward sliding mechanism guides the two first adjusting slides and the two first adjusting slots, causing the two first clamping plates to move away from each other. This releases the clamping and fixing of the cut end of the sewing thread, allowing the cut end of the sewing thread to be fixed on the winding mechanism for winding. The four mounting brackets, under the elastic force of the four return springs, more smoothly drive the two first clamping plates and the two second clamping plates to move away from each other. The above operation is simple and practical, with a reasonable and compact structure. This device achieves the fixing of the sewing thread cutting position and the conveying operation, improving the cutting and collection quality of the sewing thread and enhancing the practicality of the device.

[0023] A cutting structure in the sewing thread processing process, such as Figure 1-4As shown, the device includes a cutting mechanism 10 and a rodless cylinder 11 disposed below the cutting mechanism 10. A winding mechanism 12 and a guide roller assembly 13 are respectively disposed at the front and rear ends of the rodless cylinder 11. The cutting mechanism 10, winding mechanism 12, and guide roller assembly 13 are all prior art and will not be described in detail. A movable housing 15 is fixedly mounted on the surface slide of the rodless cylinder 11. A clamping mechanism is disposed on the top of the movable housing 15. The clamping mechanism includes four mounting brackets 17 arranged in a matrix on the top of the movable housing 15, and two first clamping plates 19 and two second clamping plates 2 fixedly mounted at the ends of the four mounting brackets 17 close to each other. 0. Four mounting brackets 17 are provided with four limiting slide rods 16 at their far ends, which penetrate the left and right side walls of the movable housing 15. An adjustment mechanism is provided inside the movable housing 15 to move the four limiting slide rods 16 left and right. The adjustment mechanism includes an adjustment slide plate 21 slidably connected to the bottom of the movable housing 15, two first adjustment slots 22 symmetrically opened at the rear side of the top wall of the adjustment slide plate 21, and two second adjustment slots 23 symmetrically opened at the front side of the top wall of the adjustment slide plate 21. The two first adjustment slots 22 are slidably connected to the two limiting slide rods located at the rear side. Two first adjusting slide columns 24 are fixedly connected to one end of the slide rod 16. Two second adjusting slide columns 25 are slidably connected inside the two second adjusting through slots 23 and are fixedly connected to one end of the two limiting slide rods 16 located at the front side. An adjusting electric push rod 26 for driving the front and rear ends of the adjusting slide plate 21 is fixedly installed on the rear wall of the movable box 15. Two first clamping plates 19 are symmetrically arranged on the two mounting brackets 17 located at the rear side with their ends close to each other. Two second clamping plates 20 are symmetrically arranged on the two mounting brackets 17 located at the front side with their ends close to each other. All four mounting brackets 17 are L-shaped and symmetrically arranged. Four limit slide rods 16 are located on the outer side of one end of the movable housing 15, and four return springs 18 are sleeved on the outer side. The two ends of the four return springs 18 are fixedly connected to the outer wall surface of the movable housing 15 and the outer wall surface of the four mounting brackets 17, respectively. The two first adjustment channels 22 are L-shaped and the front ends of the two first adjustment channels 22 are set in a parallel state. The two second adjustment channels 23 are set in an inclined state. The front ends of the two first adjustment channels 22 correspond to the front ends of the two second adjustment channels 23, respectively. The telescopic end of the adjusting electric push rod 26 extends into the inner cavity of the movable housing 15 and is fixedly installed with the rear end of the adjusting slide plate 21.

[0024] The working principle of this utility model is as follows: In use, the winding mechanism 12 winds up the sewing thread, and the guide roller assembly 13 guides the sewing thread, allowing it to pass stably between the two first clamping plates 19 and the two second clamping plates 20. When the sewing thread needs to be cut, the rodless cylinder 11 moves the moving housing 15 to a position below the cutting mechanism 10. The telescopic end of the adjusting electric push rod 26 drives the adjusting slide plate 21 to slide towards the rear of the inner cavity of the moving housing 15, forcing the two first adjusting slide columns 24 and the two second adjusting slide columns 25 forward along the inside of the two first adjusting slots 22 and the two second adjusting slots 23, respectively. The sliding mechanism moves the thread closer to each other. The two first adjusting slide columns 24 and two second adjusting slide columns 25 drive the four limiting slide rods 16 to move closer to each other. The four limiting slide rods 16 drive the four mounting brackets 17 to compress the four return springs 18, causing the two first clamping plates 19 and two second clamping plates 20 to move closer to each other. This clamps and fixes the thread at the front and rear ends of the cutting position, improving the stability of the cutting position and enhancing the cutting effect of the cutting mechanism 10. After cutting the thread, the winding mechanism 12 continues to wind the thread, while the rodless cylinder 11 moves the two first clamping plates 19 and two second clamping plates 20 through the moving housing 15. Plate 20 moves forward synchronously with the winding mechanism 12 at its winding speed, ensuring that the cut end of the sewing thread can be fully wound up while taut, thus improving the winding quality of the winding mechanism 12. The telescopic end of the adjusting electric push rod 26 drives the adjusting slide plate 21 to slide forward a distance along the inner cavity of the moving housing 15. This causes the two second adjusting slide columns 25, guided by the two second adjusting slots 23, to move the two second clamping plates 20 away from each other, releasing the clamping and fixing of the cut end of the sewing thread. When the winding mechanism 12 is replaced and sewing thread winding is required, the telescopic end of the adjusting electric push rod 26 is again controlled to drive the adjusting slide plate 21 along the inner cavity of the moving housing 15. Continuing to slide forward, the two first adjusting slide columns 24, guided by the two first adjusting through slots 22, cause the two first clamping plates 19 to move away from each other, releasing the clamping and fixing of the cut end of the sewing thread. The cut end of the sewing thread can then be fixed on the winding mechanism 12 for winding. The four mounting brackets 17, under the elastic force of the four return springs 18, more smoothly drive the two first clamping plates 19 and the two second clamping plates 20 to move away from each other. The above operation is simple and practical, with a reasonable and compact structure. It realizes the fixing of the sewing thread cutting position and the conveying operation, improves the cutting and collection quality of the sewing thread, and enhances the practicality of the equipment.
