Description

Technical Field

[0001] This utility model relates to the field of fabric slitting technology, specifically a fabric slitting device for trouser production. Background Technology

[0002] The fabric slitting device in trouser production is a specialized machine used in garment processing equipment to cut large rolls of fabric into smaller rolls of specific widths or lengths. It is mainly used in the pre-production process of trousers.

[0003] An existing fabric slitting device for trouser production uses a cutter to cut large rolls of fabric. However, the cutter wears down over time, and continued use of a worn cutter results in severe fraying of the cut fabric. In severe cases, this can lead to uneven width of the cut fabric, rendering it unusable and causing material loss. Furthermore, existing devices lack a means to detect the degree of cutter wear, requiring operators to visually inspect the cutter. This method is not only inefficient but also makes it difficult to accurately observe cutter wear with the naked eye.

[0004] Therefore, a fabric rolling device for trouser production is proposed. Utility Model Content

[0013] Compared with the prior art, this utility model provides a fabric slitting device for trouser production, which has the following beneficial effects: During the fabric cutting process, the slitting blade is subjected to pressure from the movement of the fabric. The blade pressure sensor detects the magnitude of this pressure. As the slitting blade is used over time, its surface wears down to varying degrees. This wear increases the contact area between the slitting blade and the fabric, leading to greater pressure on the blade. The pressure sensor transmits the detected pressure changes to the pressure integrated processor via a pressure signal transmission line. The processor analyzes and records these pressure changes. When the pressure exceeds the blade's rated value, it indicates severe damage, rendering the blade unusable and requiring immediate replacement. The pressure integrated processor can monitor the pressure of multiple slitting blades, improving the accuracy of damage assessment and preventing severe burrs and uneven cutting during fabric slitting, thus avoiding material waste.

[0016] 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.

[0017] Example 1: See Figure 1 — Figure 6A fabric slitting and rolling device for trouser production includes a base plate 1. A support column 13 is welded to each of the four corners of the top of the base plate 1. An operating platform 12 is welded to the top of each support column 13. A winding assembly 11 is installed on one side of the top of the operating platform 12. A tension conveying assembly 10 is fixed to the top of the operating platform 12. Two support assemblies 5 are fixed to one side of the top of the operating platform 12. A fixing frame 15 is fixed to the top of the operating platform 12. A cylinder 8 is bolted to the top of the fixing frame 15. The output end of the cylinder 8 passes through the interior of the fixing frame 15 and is fixed to a positioning frame 9. The frame 9 has a fixed rod 6 welded inside. Multiple cutter pressure sensors 7 are fixedly mounted at equal intervals on the outside of the fixed rod 6. A slitting blade 17 is fixed inside the cutter pressure sensor 7. The bottom of the slitting blade 17 extends out of the cutter pressure sensor 7. A pressure signal transmission line 3 is connected to one side of the cutter pressure sensor 7. A pressure integrated processor 4 is installed on one side of the fixed frame 15 by bolts. The fixed rod 6 and the pressure integrated processor 4 work together. A dust collection assembly 2 is installed on the top of the base plate 1. A dust collection cover 16 is fixed to the bottom of the fixed frame 15 by bolts.

[0018] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a large roll of fabric to be cut is fixed between two support components 5. Then, one end of the fabric is passed under the fixing frame 15. The extension of the output end of the control cylinder 8 drives the positioning frame 9 downwards, causing the bottom ends of multiple slitting blades 17 to press the fabric above the slitting blades 17 and the dust collection hood 16. The device then starts, pulling the fabric. As the fabric is pulled, it continuously passes under the fixing frame 15, while the multiple slitting blades 17 cut the fabric. During the cutting process, the slitting blades 17 are subjected to pressure from the movement of the fabric. The blade pressure sensor 7 can detect the magnitude of the pressure on the slitting blades 17. As the slitting blades 17 are used for a longer period, their surfaces will experience varying degrees of wear. When the fabric is slit after the surface is worn, the contact area between the slitting blade 17 and the fabric increases, resulting in greater pressure on the slitting blade 17. The pressure sensor 7 can transmit the detected pressure changes to the pressure integrated processor 4 through the pressure signal transmission line 3. The pressure integrated processor 4 can analyze and record the pressure value changes. When the pressure value exceeds the rated value of the slitting blade 17, it indicates that the slitting blade 17 is severely damaged and cannot continue to be used. It should be replaced immediately. The pressure integrated processor 4 can monitor the pressure of multiple slitting blades 17, thereby improving the accuracy of monitoring the damage of multiple slitting blades 17, avoiding serious burrs and uneven cutting of the fabric, and avoiding material waste.

[0019] Example 2: The winding assembly 11 includes two second fixing plates 1104 welded to both sides of the top of the operating table 12, and a winding shaft 1102 is installed between the two second fixing plates 1104 via bearings. Multiple partitions 1103 are equidistantly sleeved on the outer side of the winding shaft 1102. A drive motor 1101 is fixed to one side of one of the second fixing plates 1104 by bolts, and the output end of the drive motor 1101 is fixedly connected to one end of the winding shaft 1102. A limiting groove 1106 is opened on the top of the winding shaft 1102, and a limiting slider 1105 is welded to each side of the partition 1103. The limiting slider 1105 is slidably installed inside the limiting groove 1106. Positioning screw holes 1107 are opened inside the limiting slider 1105 and the limiting groove 1106, respectively.

[0020] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, by sliding the partition 1103, the limiting sliders 1105 welded on both sides of the partition 1103 can slide along the opening direction of the limiting groove 1106. After moving to the designated position, the partition 1103 can be fixed to the outside of the roll 1102 by inserting bolts into the positioning screw holes 1107 at the bottom of the limiting slider 1105 and the limiting groove 1106. By adjusting the spacing between multiple partitions 1103, the fabric of different widths can be rolled up. The rotation of the output end of the drive motor 1101 can drive the roll 1102 to rotate, thereby rolling up the cut fabric.

[0021] Example 3: The dust collection assembly 2 includes a collection box 202 fixed to the top of the base plate 1 by bolts, and one end of the collection box 202 is connected to a dust collection pipe 203. One end of the dust collection pipe 203 is connected to the bottom of the dust collection hood 16. A negative pressure machine 201 is installed on one side of the collection box 202. An anti-slip pad 14 is welded to each of the four corners of the bottom of the base plate 1. The tension conveying assembly 10 includes two first fixing plates 1002 fixed to the top two sides of the operating table 12. The two first fixing plates 1002 are installed between the two rollers 1102 through bearings. A gearbox 1003 of a reduction motor is installed on one side of one of the first fixing plates 1002. The gearbox 1003 of the reduction motor drives the two conveying rollers 1001 to rotate in opposite directions through gears. The support assembly 5 includes a bracket 501. A limit block 503 is installed on the top of the bracket 501 through a rotating shaft. The limit block 503 and the bracket 501 are fixedly connected by a limit bolt 502.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, starting the negative pressure machine 201 can create negative pressure inside the collection box 202. The dust suction pipe 203 can suck the flying lint generated during the fabric cutting process into the collection box 202 through the dust collection hood 16, avoiding contamination of the device. The gearbox 1003 of the reduction motor can drive the two conveying rollers 1001 to rotate in opposite directions, thereby controlling the tension and conveying the fabric between the two conveying rollers 1001, ensuring the normal cutting of the fabric. When fixing the large roll of fabric, the limiting blocks 503 rotatably installed on the top of the two support components 5 are opened. Then, the two ends of the large roll of fabric are clamped on the top of the bracket 501. Then, the limiting blocks 503 and the bracket 501 are fixed with the limiting bolts 502 to fix the large roll of fabric between the two support components 5.

[0023] Working principle: In use, open the limiting blocks 503 rotatably mounted on the top of the two support components 5, then clamp the two ends of the large roll of fabric onto the top of the bracket 501. Then, fix the limiting blocks 503 and the bracket 501 with the limiting bolts 502 to fix the large roll of fabric between the two support components 5. Then, pass one end of the fabric through the bottom of the fixing frame 15 and between the two conveying rollers 1001. By sliding the partition 1103, the limiting sliders 1105 welded on both sides of the partition 1103 can slide along the opening direction of the limiting groove 1106 and move to the designated position. After placement, bolts are inserted into the positioning screw holes 1107 at the bottom of the limiting slider 1105 and the limiting slide groove 1106 to fix the partition 1103 to the outside of the roll 1102. By adjusting the spacing between the multiple partitions 1103, the fabric of different widths can be rolled up. Then the device is started to pull the fabric. After being pulled, the fabric will continuously pass under the fixing frame 15, while the multiple cutting blades 17 will cut the fabric. The rotation of the output end of the drive motor 1101 can drive the roll 1102 to rotate, thereby rolling up the cut fabric.
