Description

Technical Field

[0001] The present application relates to the technical field of corduroy fabric production equipment, and in particular to a strip cutting machine with adjustable cutter positions. Background Art

[0002] Corduroy fabric is a fabric with multiple mutually parallel wale lines on its surface; the wale lines on its surface are formed by the process of "cutting weft for raising pile", that is, by cutting the weft on the surface of the fabric with a strip cutting machine, so as to form a groove-like structure on the surface of the fabric, and correspondingly, multiple wale lines are formed. Generally speaking, corduroy fabrics can be divided into different types according to the different distances between adjacent two wale lines on the surface of the corduroy fabric.

[0003] A strip cutting machine for corduroy fabric production generally includes a frame, a rotating roller is rotatably arranged on the frame, a cutter is arranged on the rotating roller, and a plurality of cutters are arranged at intervals along the axial direction of the rotating roller; a motor is arranged on the frame to drive the rotating roller to rotate, so as to drive the cutter to rotate around the axis of the rotating roller to cut the weft on the surface of the fabric on one side of the cutter.

[0004] Regarding the above related technology, the inventor believes that the cutter is generally directly fixedly installed on the rotating roller, resulting in a relatively fixed distance between adjacent wale lines on the surface of the processed corduroy fabric, making it difficult for the strip cutting machine to be applicable to the production and processing of different types of corduroy fabrics, so it needs to be improved. Summary of the Invention

[0005] The purpose of the present application is to provide a strip cutting machine with adjustable cutter positions to adjust the distance between adjacent two cutters, so as to adjust the distance between the wale lines on the surface of the processed corduroy fabric, thereby improving the applicability of the strip cutting machine to the production of different types of corduroy fabrics.

[0006] A strip cutting machine with adjustable cutter positions provided by the present application adopts the following technical solution:

[0007] A strip cutting machine with adjustable cutter positions includes a machine base, a plurality of rotating rollers are sequentially arranged along the length direction of the machine base, and the rotating rollers are rotatably connected to the machine base; the rotating roller is connected with a driving member for driving its own rotation; a supporting roller for supporting the fabric is rotatably arranged at a position below each rotating roller of the machine base, and guiding rollers for abutting against the upper surface of the fabric are rotatably arranged at positions on both sides of the supporting roller of the machine base, and the guiding rollers are located below the supporting roller; an installation rod is slidably arranged along the axial direction of the rotating roller, and a plurality of cutters for cutting the fabric are sequentially arranged along the axial direction of the rotating roller on the installation rod; a driving assembly for driving the installation rod to move is arranged on the rotating roller.

[0008] By adopting the above technical solution, the driving assembly is used to drive the installation rod to move, thereby adjusting the positions of all the cutters connected to the corresponding installation rod, so that the cutters on two adjacent rotating rollers can be arranged alternately along the axial direction of the rotating roller, so as to cut the required velvet strips on the surface of the cloth. By adjusting the position of the corresponding installation rod by the driving assembly, the distance between the cutters on the two adjacent rotating rollers along the axial direction of the rotating roller can be adjusted to adjust the distance between adjacent velvet strips formed on the surface of the produced cloth, thereby facilitating the improvement of the applicability of the production of different types of corduroy cloth.

[0009] Compared with the conventional method in which the position of each cutter is adjustable relative to the corresponding rotating roller, the cutters on multiple rotating rollers cooperate with each other, and the distance between two adjacent velvet strips of the produced cloth can be adjusted by simply adjusting the position of the mounting rod on each rotating roller. The operation is simpler, more convenient and labor-saving.

[0010] Optionally, the driving assembly includes a driving screw rotatably connected to the rotating roller and a fixing stud for abutting against the peripheral wall of the driving screw; the mounting rod is provided with a driving screw hole mating with the driving screw thread and a fixing screw hole mating with the fixing stud thread.

[0011] By adopting the above technical solution, the installation rod can be moved by rotating the driving screw rod, which is simple and convenient to operate. When the position adjustment of the installation rod is completed, the fixing stud is rotated so that the fixing stud rod is tightly pressed against the peripheral wall of the driving screw rod, thereby limiting the rotation of the driving screw rod and achieving the effect of locking the installation rod.

[0012] Optionally, a fixing block is provided in the fixing screw hole, and the fixing stud abuts against an end wall of the fixing block at an end away from the driving screw rod; the fixing block abuts against an external thread of the driving screw rod.

[0013] By adopting the above technical solution, the fixing stud abuts against the driving screw rod through the fixing block, which is beneficial to reducing the wear between the external threads of the fixing stud and the driving screw rod.

[0014] Optionally, a connecting seat is provided between the support roller and the machine base, and the support roller is connected to the machine base via the connecting seat; the support roller is rotatably connected to the upper end of the connecting seat; the lower end of the connecting seat is rotatably connected to the machine base, and the machine base is provided with a fixing part for fixing the connecting seat.

[0015] By adopting the above technical solution, loosening the fixing part and rotating the connecting seat, the supporting roller can be driven to move, so that the cloth and its corresponding cutter are separated, thereby further increasing the distance between two adjacent velvet strips on the cloth surface, so as to further improve the applicability of the production of various types of corduroy cloth.

[0016] Optionally, the machine base is provided with an air collecting hood, and the mouth of the air collecting hood is arranged towards the direction of the cutting knife; the air collecting hood is connected with an air suction pipe, the air suction pipe is connected with a filter housing, and the filter housing is connected with a negative pressure source; a filter element for filtering the gas flowing towards the negative pressure source is arranged in the filter housing.

[0017] By adopting the above technical solution, the negative pressure source can suck the thread ends, fluff, etc. generated by the cutting knife cutting the fabric into the filter housing through the air suction pipe and the air collecting hood, so as to reduce the thread ends, fluff and other sundries in the production workshop, which is beneficial to improving the air quality in the workshop and keeping the workshop clean.

[0018] Optionally, the filter element is in a hollow cylindrical shape, and the filter housing is provided with a support plate for supporting the filter element; the support plate is provided with ventilation holes communicating with the inside of the filter element, and the air inlet end of the negative pressure source communicates with the inside of the ventilation holes.

[0019] By adopting the above technical solution, the filter element is in a hollow cylindrical shape, which is beneficial to increasing the contact area between the filter element and the gas in the filter housing, thereby improving the filtering efficiency of the gas in the filter housing.

[0020] Optionally, a rotating rod is rotatably arranged on the inner side wall of the filter housing around the axis of the filter element, and a cleaning scraper for abutting against the outer peripheral wall of the filter element is arranged on the rotating rod; the filter housing is provided with a rotating member for driving the rotating rod to rotate.

[0021] By adopting the above technical solution, the rotating member drives the rotating rod to rotate, so that the cleaning scraper moves relative to the filter element to scrape the sundries attached to the outer peripheral wall of the filter element, reducing the possibility of the filter element being blocked, which is beneficial to ensuring the filtering effect of the filter element.

[0022] Optionally, the cleaning scraper is spiral along the circumferential direction of the filter element, and the lower surface of the cleaning scraper is used for abutting against the outer peripheral wall of the filter element; a cleaning scraper for abutting against the lower surface of the cleaning scraper is slidably arranged on the inner side wall of the filter housing in the up and down direction, and a gap for the cleaning scraper to pass through is arranged between the lower end wall of the cleaning scraper and the upper surface of the support plate; the cleaning scraper is connected with an elastic resetting member for driving it to move upward.

[0023] By adopting the above technical solution, the rotating rod drives the cleaning scraper to rotate, so that the lower surface of the cleaning scraper scrapes the sundries on the outer peripheral wall of the filter element downward, which is conducive to the downward sliding of the sundries; when the lower surface of the cleaning scraper abuts against the cleaning scraper, the cleaning scraper can move downward; during the downward movement of the cleaning scraper, the cleaning scraper can push the sundries on the lower surface of the cleaning scraper downward, so as to further facilitate the downward falling and gathering of the sundries, so as to facilitate the unified cleaning of the sundries, and at the same time reduce the possibility of the sundries being lifted again and blocking the filter holes of the filter element. When the cleaning scraper moves to the position of the lower end wall of the cleaning scraper, the cleaning scraper is separated from the cleaning scraper, and the elastic reset member drives the cleaning scraper to move upward and reset, so that the cleaning scraper can abut and cooperate with the cleaning scraper again.

[0024] Optionally, a blanking hole is provided through the upper surface of the support plate downward; an operation hole is provided through the peripheral wall of the filter housing, and a receiving frame for receiving the sundries falling from the blanking hole is slidably connected to the inner side wall of the operation hole; a blocking plate for sealing the blanking hole is slidably provided on the support plate.

[0025] By adopting the above technical solution, the sundries scraped off by the cleaning scraper can automatically fall under the action of their own gravity and can fall into the receiving frame through the blanking hole. When it is necessary to clean the receiving frame, slide the blocking plate to block the blanking hole, and then the receiving frame can be taken out from the operation hole, and the operation is convenient; at the same time, it is beneficial to keep the negative pressure source running continuously, so as to ensure the continuous filtration of the gas in the filter housing by the filter element, so as to ensure the filtration efficiency of the gas in the workshop.

[0026] Optionally, the sliding direction of the blocking plate is arranged along the sliding direction of the receiving frame; the blocking plate is located on the side of the blanking hole away from the operation hole; an elastic member for driving the blocking plate to move towards the operation hole is provided on the support plate; the blocking plate is provided with an abutting block extending downward, and the abutting block can abut against the outer end wall of the end of the receiving frame away from the operation hole; a locking member for fixing the receiving frame is provided on the filter housing.

[0027] By adopting the above technical solution, when it is necessary to clean the receiving frame, loosen the locking member, and the elastic member drives the blocking plate to move towards the operation hole to block the blanking hole; at the same time, the abutting block pushes the receiving frame to push the receiving frame outwards, so as to facilitate the removal of the receiving frame from the operation hole. When the receiving frame is cleaned, when the receiving frame is inserted into the operation hole and pushed, the receiving frame can push the abutting block to drive the blocking plate to move, so as to open the blanking hole, so that the sundries above the support plate can fall into the receiving frame.

The connecting block 528 is located on the side of the abutting block 5251 away from the operation hole 56, and the connecting block 528 is welded and fixed to the lower surface of the support plate 52. The elastic member 527 includes a spring, and the elastic member 527 is located between the connecting block 528 and the abutting block 5251; one end of the elastic member 527 abuts against the connecting block 528, and the other end abuts against the abutting block 5251, so that the abutting block 5251 and the material receiving frame 561 are kept in a tight state. The filter housing 5 is provided with a locking member 57 for fixing the material receiving frame 561.

[0060] Reference Figure 8 The locking member 57 is in the shape of a rod; one end of the locking member 57 is rotatably connected to the outer peripheral wall of the filter housing 5 through a pin shaft. The axial direction of the pin shaft of the locking member 57 is arranged along the radial direction of the filter housing 5; the locking member 57 is rotated, and the locking member 57 can abut against the outer side wall of the material receiving frame 561 to limit the movement of the material receiving frame 561 to the outside of the operation hole 56, thereby fixing the material receiving frame 561. When the locking member 57 is rotated to be separated from the material receiving frame 561, the elastic member 527 drives the blocking plate 525 to move toward the direction of the operation hole 56, so that the blocking plate 525 blocks the blanking hole 524; at the same time, the blocking plate 525 pushes the material receiving frame 561 to the outside of the operation hole 56 through the abutment block 5251, so that the material receiving frame 561 can be removed.

[0061] The implementation principle of the embodiment of the present application is:

[0062] When in use, the cloth is sequentially wound around all the guide rollers 12 and the support roller 311 so that the cloth is located between the rotating roller 2 and the support roller 311, and the lower surface of the cloth is in contact with the peripheral wall of the support roller 311; then the driving screw 231 is rotated to adjust the distance between the cutters 21 of two adjacent rotating rollers 2 along the axial direction of the rotating roller 2, and the driving screw 231 is locked by the fixing stud 232; finally, the connecting rod 31 is rotated and fixed by the fixing member 13 so that the weft of the surface of the cloth at the position of the support roller 311 contacts the cutter 21, so that the cutter 21 cuts the weft of the cloth, thereby forming velvet strips on the surface of the cloth; the distance between two adjacent velvet strips is equal to the distance between the corresponding two cutters 21 along the axial direction of the rotating roller 2.

[0063] The driving screw 231 can adjust the position of each mounting rod 221, thereby adjusting the distance between two adjacent cutters 21 along the axial direction of the rotating roller 2, so as to be suitable for the production of different types of corduroy fabrics.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
