Description

Technical Field

[0001] This utility model relates to the field of cotton sliver cutting technology, specifically to a cotton sliver cutting device for spinning. Background Technology

[0002] Spinning involves first dyeing the fibers, then thoroughly mixing the fibers of different colors before spinning them into yarn with a unique blended effect. Because this process uses dyeing before spinning, it saves more than 50% of water and reduces emissions compared to the traditional spinning-before-dyeing process. Color-spun yarn fibers are first carded into slivers, then cut into short slivers before dyeing. A cutting device is required when cutting the slivers.

[0003] In the existing technology, the fixed installation method of the cutting blade is to weld the cutting blade directly to the blade holder or blade disc base to form a permanent connection in order to pursue structural stability. When the cutting blade wears out, it cannot be replaced individually and must be scrapped as a whole, which increases the maintenance cost of the device. If stress cracks occur at the weld, it needs to be returned to the factory for re-welding, which has a long maintenance cycle and affects the production line scheduling.

[0004] This utility model proposes a spinning sliver cutting device to solve the problem that the cutting blade is directly welded to the blade holder or blade disc base to form a permanent connection, and cannot be replaced separately when the cutting blade is worn. Summary of the Invention

[0011] Further defining the above technical solution, a roller-type meter-counting sensor is provided on the inner top wall of the upper mounting base, and the bottom of the roller-type meter-counting sensor is in contact with the top of the first traction roller. A controller is installed on the right side of the base, and the output end of the roller-type meter-counting sensor is electrically connected to the input end of the controller. The output end of the controller is electrically connected to the input end of the drive motor.

[0012] To further define the above technical solution, a cutting groove is provided in the middle of the top of the support frame.

[0013] Further defining the above technical solution, the clamping structure includes multiple movable rods, which are respectively movably inserted into the four corners of the mounting plate. Each of the multiple movable rods has a baffle fixedly installed at its top and a pressure plate fixedly installed at its bottom. Each of the multiple movable rods has a return spring sleeved on its outer side, and the return spring is located between the mounting plate and the pressure plate.

[0014] Further defining the above technical solution, the connection structure includes a connecting groove, which is fixedly installed in the middle of the bottom of the mounting plate.

[0026] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0027] Example 1: This example provides a yarn sliver cutting device, such as... Figure 1 and Figure 4 As shown, this invention solves the problem of the cutting blade being directly welded to the blade holder or blade disc base, forming a permanent connection, and being unable to be replaced individually when the cutting blade wears out. It includes a base 1, a traction structure 2 at one end of the top of the base 1, a support frame 3 at the end of the top of the base 1 near the traction structure 2, a support plate 4 fixedly installed at the rear end of the top of the support frame 3, a second electric push rod 5 installed on the inner top wall of the support plate 4, an installation plate 6 fixedly installed at the bottom of the second electric push rod 5, a clamping structure 7 at each of the four corners of the installation plate 6, a connecting structure 9 at the middle of the bottom of the installation plate 6, a cutting blade 10 installed at the bottom of the connecting structure 9, and a conveying structure 8 at the other end of the top of the base 1.

[0028] The connecting structure 9 is used for the disassembly and assembly of the cutting blade 10.

[0029] Combination Figure 1 and Figure 3 In an embodiment of this utility model, the traction structure 2 includes a frame 21, which is fixedly installed at one end of the top of the base 1. A lifting member 22 is provided at the top of the frame 21, and an upper mounting seat 23 is installed at the bottom of the lifting member 22. A first traction roller 24 is rotatably connected between the upper mounting seats 23. A lower mounting seat 26 is fixedly installed on the inner bottom wall of the frame 21, and a second traction roller 27 is rotatably connected between the lower mounting seats 26. A drive motor 28 is fixedly installed on the outer side of both the upper mounting seat 23 and the lower mounting seat 26, respectively for driving the first traction roller 24 and the second traction roller 27 to rotate. The two sets of drive motors 28 rotate in opposite directions.

[0030] Combination Figure 1 and Figure 3 In an embodiment of this utility model, the lifting component 22 includes a first electric push rod 221, which is fixedly inserted into the middle of the top of the frame 21. A lifting plate 222 is fixedly installed at the bottom of the first electric push rod 221. Guide rods 223 are fixedly connected to both ends of the top of the lifting plate 222. The tops of the two sets of guide rods 223 extend out of the frame 21. Guide holes 224 are provided at both ends of the top of the frame 21 for cooperating with the guide rods 223.

[0031] The cotton strip to be cut is placed between the first traction roller 24 and the second traction roller 27. The first electric push rod 221 is extended to drive the lifting plate 222 to move downward. As the lifting plate 222 moves downward, it drives the guide rod 223 to slide inside the guide hole 224, thereby making the lifting plate 222 more stable when it moves downward. As the lifting plate 222 moves downward, it drives the first traction roller 24 to move downward and contact the top of the cotton strip. Then the drive motor 28 is started. When the drive motor 28 is working, it drives the first traction roller 24 and the second traction roller 27 to rotate in opposite directions, thereby driving the cotton strip to move to the right.

[0032] Combination Figure 1 In an embodiment of this utility model, a cutting groove 31 is provided in the middle of the top of the support frame 3.

[0033] After the cotton strip moves a certain distance, the second electric push rod 5 is activated. The second electric push rod 5 drives the mounting plate 6 and the cutting blade 10 to move downward. Through the cooperation of the cutting groove 31, the cotton strip can be cut by the cutting blade 10.

[0034] Combination Figure 1 and Figure 4 In an embodiment of this utility model, the connecting structure 9 includes a connecting groove 91, which is fixedly installed in the middle of the bottom of the mounting plate 6. A connecting seat 92 is fixedly connected to the top of the cutting blade 10 for engaging with the connecting groove 91. A locking bolt 93 is screwed onto the right side of the connecting groove 91, with one end of the locking bolt 93 extending into the interior of the connecting groove 91. A screw hole 94 is provided on the right side of the connecting groove 91 for threaded connection with the locking bolt 93.

[0035] When the cutter 10 becomes worn and unusable, the operator unscrews the locking bolt 93 from the screw hole 94 to release the locking bolt 93 from the fixing effect on the connecting seat 92. At this time, the cutter 10 is pulled down to separate the connecting seat 92 from the connecting groove 91, so that the cutter 10 can be disassembled and replaced, reducing the maintenance cost of the device.

[0036] Example 2: Reference Figure 1To address the problem that the device cannot effectively compress and fix the cotton strip during the cutting process, which can easily lead to the cotton strip shifting, the compression structure 7 includes multiple movable rods 71, which are movably inserted into the four corners of the mounting plate 6. Each of the multiple movable rods 71 ​​has a baffle 72 fixedly installed on its top and a pressure plate 73 fixedly installed on its bottom. Each of the multiple movable rods 71 ​​has a return spring 74 sleeved on its outer side, and the return spring 74 is located between the mounting plate 6 and the pressure plate 73.

[0037] When the second electric push rod 5 pushes the mounting plate 6 downward, the pressure plate 73 first contacts the top of the cotton strip. As the mounting plate 6 continues to move downward, the movable rod 71 slides inside the mounting plate 6 and compresses the return spring 74. At this time, the pressure plate 73 presses against the top of the cotton strip through the return spring 74 to press and fix the cotton strip, thereby improving the stability of the cotton strip during the cutting process and improving the cutting quality.

[0038] Example 3: Reference Figure 1 and Figure 3 To address the problem that existing devices cannot achieve fixed-length cutting, a roller-type meter sensor 25 is installed on the inner top wall of the upper mounting base 23, and the bottom of the roller-type meter sensor 25 is in contact with the top of the first traction roller 24. A controller is installed on the right side of the base 1, and the output end of the roller-type meter sensor 25 is electrically connected to the input end of the controller. The output end of the controller is electrically connected to the input end of the drive motor 28.

[0039] When the cotton sliver is being pulled and conveyed, the first traction roller 24 is always in contact with the roller-type meter sensor 25. Therefore, the length of the cotton sliver being conveyed can be calculated by the roller-type meter sensor 25. When the cotton sliver reaches the required length, the roller-type meter sensor 25 transmits a signal to the controller. The controller shuts off the drive motor 28, and the cotton sliver stops being conveyed, so that the cutting length of the cotton sliver can be accurately recorded.

[0040] Combination Figure 1 and Figure 2 In an embodiment of this utility model, the conveying structure 8 includes two sets of first vertical plates 81, both of which are installed on the top of the base 1 near the support frame 3. A first roller 82 is rotatably installed between the two sets of first vertical plates 81. A stepper motor 83 is fixedly installed on the outer side of one of the first vertical plates 81 to drive the first roller 82 to rotate. A second vertical plate 84 is installed on the top of the base 1 away from the two sets of first rollers 82. A second roller 85 is rotatably installed between the two sets of second vertical plates 84. A conveyor belt 86 is externally driven by the first roller 82 and the second roller 85.

[0041] The first roller 82 is driven to rotate by the stepper motor 83. The rotation of the first roller 82 drives the conveyor belt 86 to rotate, and the rotation of the conveyor belt 86 drives the second roller 85 to rotate. After the cotton sliver is cut, the cotton sliver can continue to move to the right under the rotation of the conveyor belt 86, ensuring that the entire production process continues uninterrupted.

[0042] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
