Description

Technical Field

[0001] The invention relates to a wool shearing machine, in particular to a wool shearing machine used for fabric shearing production. Background Art

[0002] In the textile industry, pattern cutting is a process for deep processing of fabric surface cloth, and the processing objects are generally velvet and fabrics with relatively long velvet. Pattern cutting is generally completed on a shearing machine by a pattern shearing roller that lifts up the fabric, and the velvet part that is pushed out from the convex part of the pattern shearing roller is cut off, while the velvet part that is not pushed out from the concave part of the pattern shearing roller is not cut, thus forming a protruding pattern velvet. However, there is generally only one set of pattern shearing rollers installed on the shearing machine. Once the shearing roller is damaged, or the shearing roller needs to be replaced due to the need to change the type of shearing pattern, it is necessary to stop the machine for disassembly and replacement, which is not only time-consuming and labor-intensive, but also increases the labor intensity of the operator.

[0003] Therefore, there is an urgent need for a shearing machine for fabric shearing production which has a simple structure, is easy to maintain and replace, and has a time-saving and labor-saving replacement operation. Summary of the invention

[0004] The purpose of the present invention is to provide a shearing machine for fabric shearing production, which has a simple structure, is convenient to maintain and replace, and the replacement operation is also relatively time-saving and labor-saving.

The cloth guide roller is arranged between the two sets of side plates, and its two ends are rotatably connected to the two sets of side plates. There is a gap between the cloth guide roller and the lowest shearing roller body for the fabric to pass through.

[0008] Preferably, the plurality of groups of first blades are distributed in a spiral shape on the side wall of one group of shearing roller bodies.

[0009] Preferably, a plurality of groups of second blades are equally spaced around the side walls of another group of shearing roller bodies.

[0010] Furthermore, the support block is a counterweight block, which is symmetrically distributed on both sides of the bottom of the connecting block, and through its own weight, when the rotating shaft rotates, the shearing roller body keeps the counterweight block downward by self-rotation.

[0011] Preferably, the shearing roller group further comprises two groups of annular slide rails, which are correspondingly arranged on the two groups of rotating frames and are rotatably connected to the annular slide grooves on the inner sides of the side plates.

[0013] Preferably, support legs are provided at the bottom of the support plate.

[0014] Preferably, the shearing roller bodies are symmetrically distributed on both sides of the rotating shaft.

DETAILED DESCRIPTION

[0023] Combination Figures 1 to 4The shearing machine for fabric shearing production shown in the figure, in this embodiment, includes a frame group 1, a shearing roller group 2 installed on the frame group 1 and a first driving group for driving the shearing roller group 2 to rotate; the frame group 1 includes two groups of side plates 11 arranged opposite to each other and a support plate 12 connected between the side plates 11, the shearing roller group 2 includes a rotating frame 21, a shearing roller body 22 and a rotating shaft 23, the rotating frame 21 is provided with two groups, and is rotatably connected to the two groups of side plates 11 through the rotating shaft 23 in a one-to-one manner, one end of the rotating shaft 23 is fixed to the rotating frame 21, and the other end passes through the side plate 11 and is driven and connected to the first driving group installed on the outer side of the side plate 11, the two groups of shearing roller bodies 22 are arranged in parallel between the two groups of rotating frames 21, and the short shafts at both ends of the shearing roller bodies 22 pass through the rotating frame 21; the ends of the short shafts are connected with connecting blocks 24 Two groups of support blocks 25 are also fixed to the bottom of the connecting block 24, and an electric push rod 26 is installed on the support block 25. The movable end of the electric push rod 26 is fixed with a limit block 27. In this embodiment, in order to improve the stability of the limit block movement, a guide sleeve 6 for a linear guide limit block can be provided outside the limit block, and a matching gap is formed between the two groups of limit blocks 27. A second driving group 28 is also installed on the side plate 11. The movable end of the second driving group 28 passes through the side plate 11 and is fixed with a matching block 29. The matching block 29 is placed in the matching gap, and the side surfaces on both sides are matched and limited with the side surfaces of the two groups of limit blocks 27. The shearing roller body 22 is driven to rotate by the rotation of the second driving group 28. A blade for shearing is also provided on the side wall of the shearing roller body 22, and in this embodiment, the first driving group and the second driving group 28 can adopt a rotating motor.

[0024] In order to improve the stability of the blade shearing effect when the shearing roller body 22 rotates, a steel cloth guide roller can be arranged under the shearing roller body 22 that rotates to the lowest side when the rotating frame 21 rotates. The cloth guide roller is arranged between the two groups of side plates 11, and its two ends are rotatably connected to the two groups of side plates 11. There is a gap between the cloth guide roller and the lowest shearing roller body 22 for the fabric to pass through.

[0025] The plurality of first blades are distributed in a spiral shape on the side wall of one of the shearing roller bodies 22 .

[0026] A plurality of groups of second blades are equally spaced around the side walls of another group of shearing roller bodies 22 .

[0027] The support block 25 is a counterweight block, which is symmetrically distributed on both sides of the bottom of the connecting block 24. Through its own weight, when the rotating shaft 23 rotates, the shearing roller body 22 keeps the counterweight block downward by self-rotation. When it is necessary to rotate the rotating frame 21 to replace the shearing roller body 22 for shearing, the counterweight block arranged at the bottom of the connecting block 24 can make the shearing roller body 22 revolve around the rotating shaft 23 while also rotating, thereby facilitating the automatic limit matching of the end faces of the matching block 29 and the limit block 27, reducing manual operations and reducing labor costs.

[0028] In order to improve the stability of the rotating frame 21 during rotation, the shearing roller group 2 also includes two groups of annular slide rails 3, which are correspondingly arranged on the two groups of rotating frames 21 and rotatably connected to the annular slide grooves on the inner sides of the side plates 11.

[0029] A sensor is also installed on the inner side of the side plate 11 above the second drive group 28, and a sensing block 4 that can cooperate with the sensor is also provided on the rotating frame 21 on one side of the shearing roller body 22. After the sensor senses the sensing block 4, the controller controls the first drive group to stop and controls the electric push rod 26 to extend. The inner side surfaces of the two groups of limit blocks 27 cooperate to limit the two outer side surfaces of the matching blocks 29, thereby limiting the second drive group 28 and the shearing roller body 22.

[0030] A supporting leg 13 is provided at the bottom of the supporting plate 12 .

[0031] The shearing roller bodies 22 are symmetrically distributed on both sides of the rotating shaft 23 .

[0032] A rectangular mounting hole is provided at the end of the short shaft, and a mounting block that fits in the rectangular mounting hole is provided at the end of the connecting block 24. The mounting block extending into the rectangular mounting hole is fixed on the short shaft by screws 5, thereby improving the detachable connection effect.

[0033] The working principle of the present invention is as follows: by arranging a rotating frame 21 between the side plates 11, and arranging a rotatably connected shearing roller body 22 between the rotating frames 21, the shearing roller body 22 can be replaced during the working process by rotating the rotating frame 21, and the shearing roller body 22 can be automatically switched and replaced by the two sets of electric push rods 26 and the matching limit blocks 27 and matching blocks 29 during replacement, which is more time-saving and labor-saving. After the limit blocks 27 and the matching blocks 29 are matched and positioned, the second drive group 28 can drive the shearing roller body 22 to rotate and shear through the connecting block 24. The overall operation process is only carried out through the rotation movement of the first drive group, and the two sets of electric push rods 26 can adopt micro electric push rods 26. Because after pushing the limit block 27, when the second drive group 28 drives the connecting block 24 to rotate, the micro electric push rod 26 is not subjected to force in the axial direction. Therefore, the micro electric push rod 26 can be adopted to reduce the overall structural weight and make the structure simpler.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
