Description

Technical Field

[0001] This application relates to the field of shearing machines, and particularly to a shearing machine. Background Art

[0002] A shearing machine is a machine used in a combined machine for brushing, ironing, and shearing, or a combined machine for raising and shearing.

[0003] Currently, the Chinese utility model patent with the publication number CN215947633U discloses a plant shearing device capable of recycling waste materials, including a spiral circular knife and a flat knife that cooperate with each other. A recycling cover is arranged above the spiral circular knife, and an arc-shaped cover surrounding the outer circumference of the spiral circular knife is arranged inside the recycling cover. An arc-shaped air guiding gap is formed between the arc-shaped cover and the spiral circular knife. The side of the air guiding gap facing the flat knife is the lower week side, and the side away from the flat knife is the upper week side. A wind guiding plate is arranged on the lower week side of the air guiding gap. A wind guiding channel is formed between the wind guiding plate and the inner wall of the recycling cover. An air extraction pipe is connected above the wind guiding channel. A brush roller is arranged in the wind guiding channel. This application has the effect of being able to recycle the trimmed fluff waste materials.

[0004] During the movement of chemical fiber fabrics relative to the flat knife, static electricity is easily generated, causing the cut scraps of hair to adsorb on the surface and internal gaps of the spiral circular knife. The scraps of hair on the surface of the spiral circular knife can be absorbed by the recycling cover, while the scraps of hair at the internal gaps will accumulate over time, and the scraps of hair will come into contact with the fabric surface again to form hair balls or defects. Summary of the Invention

[0005] In order to reduce the scraps of hair at the gaps of the spiral circular knife from being brought back to the fabric surface again to form hair balls or defects, this application provides a shearing machine.

[0006] A shearing machine provided by this application adopts the following technical solution: A shearing machine includes a shearing machine body, a spiral circular knife, a flat knife, a driving member, and an absorption assembly. The spiral circular knife is rotatably connected to the shearing machine body. The flat knife abuts against the surface of the spiral circular knife. The driving member is used to drive the spiral circular knife to rotate. The absorption assembly is used to absorb the fluff cut by the spiral circular knife and includes a cleaning assembly. The cleaning assembly includes an annular belt, a plurality of matching plates, and a plurality of scraping plates. The length of the annular belt is parallel to the length direction of the spiral circular knife. The annular belt is arranged on the shearing machine body and on one side of the spiral circular knife. A plurality of matching plates are distributed circumferentially along the annular belt. The matching plates are rotatably connected end to end. A plurality of scraping plates correspond to the plurality of matching plates. The scraping plates are arranged on the matching plates. The scraping plates abut against the gaps of the spiral circular knife.

[0007] By adopting the above technical solution, the blades of the spiral circular knife are spiral, and several blades are evenly distributed in the circumferential direction. When the spiral circular knife rotates, it will cut the lint on the fabric surface together with the flat knife. Some lint will be located in the gaps of the spiral circular knife and cannot be absorbed by the absorption component. The cleaning component is used to clean the lint in the gaps of the spiral circular knife. Several matching plates are connected end to end. When the spiral circular knife rotates, the scraping plate rotates relative to the spiral circular knife, and the scraping plate drives the matching plate to move along the annular belt, conforming to the rotation law of the spiral circular knife, and the scraping plate abuts against the gaps of the spiral circular knife. The scraping plate will separate the lint in the spiral circular knife from the spiral circular knife, reducing the lint from entering the subsequent fabric again to form lint balls or defects, and improving the production quality of the shearing machine.

[0008] Optionally, the cleaning component further includes a receiving box, the receiving box is arranged in the annular belt, a communication hole communicating with the inside of the receiving box is opened on one side of the receiving box facing the spiral circular knife, and a matching hole for guiding lint into the communication hole is opened on the scraping plate.

[0009] By adopting the above technical solution, the scraping plate scrapes the lint in the gaps of the spiral circular knife into the matching holes of the scraping plate, and the lint in the matching holes enters the receiving box through the communication hole, reducing the random floating of the lint separated from the spiral circular knife and improving the cleanliness around the shearing machine body.

[0010] Optionally, the absorption component includes a negative pressure cover, a filtering part for filtering lint, an air suction pipe and a fan. The negative pressure cover is arranged on the shearing machine body, the negative pressure cover covers the spiral circular knife and the flat knife, the fan is arranged on the shearing machine body, one end of the air suction pipe is arranged on the air inlet end of the fan, the other end of the air suction pipe is arranged on the negative pressure cover, and the filtering part is arranged on the air suction pipe.

[0011] By adopting the above technical solution, the absorption component is used to absorb the fabric lint cut by the spiral circular knife and the flat knife. The negative pressure cover is used to cover the periphery of the spiral circular knife. The fan sucks air through the air suction pipe to the negative pressure cover, and the negative pressure cover generates negative pressure on the periphery of the spiral circular knife. The lint will enter the negative pressure cover and be blocked by the filtering part, reducing the contact between the lint and the fan, prolonging the service life of the fan, and the absorption component has a simple structure and is convenient for the staff to operate.

[0012] Optionally, the filtering part includes a filtering box, a filtering rack and a filtering net. The filtering box is arranged on the shearing machine body, the air inlet pipe is communicated with the filtering box, the filtering rack is slidably connected to the filtering box, and the filtering net is arranged on the filtering rack.

[0013] By adopting the above technical solution, the filter screen is used to prevent lint from entering the fan. When there is too much lint blocked on the filter screen, the staff can remove the filter rack from the filter box and centrally process the lint on the filter screen. The filter element has a simple structure, is effective and reliable.

[0014] Optionally, a locking member for restricting the detachment of the filter rack is provided on the filter box. The locking member includes a locking rod and a locking block. The locking rod is rotatably connected to the filter box. The locking block is provided on the locking rod. A locking groove is formed on the locking block, and the locking rod is used for snap-fit connection with the locking groove.

[0015] By adopting the above technical solution, after the filter screen is cleaned, the filter rack is installed into the filter box. Then, the staff rotates the locking rod so that the locking rod is snap-fitted into the locking groove of the locking block. When the locking rod can be snap-fitted into the locking groove, it indicates that the filter rack is installed in place. The locking member facilitates the staff to identify the installation state of the mounting rack.

[0016] Optionally, the absorption assembly further includes a connecting pipe. One end of the connecting pipe is provided on the suction pipe, and the other end of the connecting pipe is provided on the receiving box.

[0017] By adopting the above technical solution, when the absorption assembly is used to absorb the lint around the spiral circular knife, the fan also makes the receiving box generate negative pressure through the connecting pipe. The negative pressure in the receiving box enables the lint in the gap of the spiral circular knife to enter the receiving box through the matching holes of the scraper, and also facilitates the transfer of the lint in the receiving box to the filter screen, reducing the separate treatment of lint by the staff.

[0018] Optionally, a fluff blowing assembly for raising the fluff on the surface of the fabric is provided on the shearing machine body. The fluff blowing assembly includes a fabric support frame and an air inlet pipe. The fabric support frame is provided on the shearing machine body. The fabric support frame is used to support the fabric. A ventilation cavity is formed in the fabric support frame. A plurality of ventilation holes are formed at the top of the fabric support frame. The ventilation holes are communicated with the ventilation cavity. One end of the air inlet pipe is provided at the air outlet end of the fan, and the other end of the air inlet pipe is provided on the fabric support frame and communicated with the ventilation cavity.

[0019] By adopting the above technical solution, the fluff blowing assembly is used to raise the fluff on the surface of the fabric, facilitating the fluff to enter between the spiral circular knife and the flat knife for cutting treatment. The fabric support frame is used to support the fabric. When the fan makes the negative pressure hood and the receiving box generate negative pressure, the fan blows the air into the air inlet pipe. The air inlet pipe introduces the air into the ventilation cavity and sprays it out from the ventilation holes, making the fluff on the fabric stand up. No additional power source is required, which conforms to the concept of green environmental protection.

[0020] Optionally, a cavity is provided in the spiral circular knife, and a cooling component for reducing the temperature of the spiral circular knife is also provided on the shearing machine body, the cooling component comprises a water pump, a water tank, a water inlet pipe and a water outlet pipe, one end of the water inlet pipe is provided on the water tank, the other end of the water inlet pipe is rotatably connected to one end of the spiral circular knife, one end of the water outlet pipe is provided on the water tank, the other end of the water outlet pipe is rotatably connected to the other end of the spiral circular knife, the water outlet pipe is connected to the water inlet pipe and the cavity, the water pump is used to pump water in the water inlet pipe into the cavity, and the water tank is provided with fins for heat dissipation.

[0021] By adopting the above technical solution, since the scraper remains in contact with the spiral circular knife, the spiral circular knife is prone to friction with the scraper, which causes the spiral circular knife to generate heat. The temperature of the spiral circular knife can be reduced by the cooling component, thereby making the cleaning component more reasonable. The water pump pumps the water in the water tank into the water inlet pipe, and the water in the water inlet pipe enters the cavity. The water entering the cavity will reduce the temperature of the spiral circular knife, thereby extending the service life of the spiral circular knife. The water in the spiral circular knife then enters the water tank from the water outlet pipe to complete a cycle.

[0022] Optionally, the cooling component includes a spiral rod, a first gear, a second gear and a driving motor, the length direction of the spiral rod is parallel to the length direction of the spiral circular knife, the spiral rod is rotatably connected to the spiral circular knife, the spiral rod abuts against the inner wall of the cavity, one end of the spiral rod passes through the spiral circular knife, the first gear is arranged on the spiral rod, the driving motor is arranged on the shearing machine body, the second gear is arranged on the output shaft of the driving motor, and the first gear is meshed with the second gear.

[0023] By adopting the above technical solution, the motor drives the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the spiral rod to rotate, the spiral rod drives the water to move in the cavity inside the spiral circular knife, and the spiral rod makes the water more evenly distributed in the spiral circular knife, reducing the imbalance when the spiral circular knife rotates.

[0024] Optionally, the driving member includes a third gear, a fourth gear and an idler gear, the third gear is arranged on the output shaft of the driving motor, the fourth gear is arranged on the spiral circular cutter, and the third gear and the fourth gear are both meshed with the idler gear.

[0025] By adopting the above technical solution, when the motor drives the first gear to rotate, it will drive the third gear to rotate, the third gear drives the idler gear to rotate, the idler gear drives the fourth gear to rotate, and the fourth gear drives the spiral circular knife to rotate. The rotation direction of the spiral circular knife is opposite to the rotation direction of the spiral rod. The spiral rod can accelerate the flow of water through the cavity in the spiral circular knife and quickly take away the heat of the spiral circular knife.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The cleaning component is used to clean the fluff in the gap of the spiral circular knife, reducing the formation of lint balls and defects on the fabric caused by the fluff contacting the fabric again; 2. The absorption component is used to absorb the fluff around the spiral circular knife and in the receiving box; 3.

[0042] Part of the cut lint will enter the gap of the spiral circular knife 2. The scraper 63 of the cleaning component 6 abuts against the gap of the spiral circular knife 2. Through the relative movement of the annular belt 61 and the matching plate 62, the scraper 63 separates the lint from the gap of the spiral circular knife 2. And the blower 54 makes the receiving box 64 generate negative pressure through the connecting pipe 55. The lint enters the receiving box 64 through the matching hole 631 of the scraper 63 and enters the filter element 52 through the connecting pipe 55, reducing the chance that the lint in the gap of the spiral circular knife 2 contacts the fabric again and forming lint balls.

[0043] Since the scraper 63 abuts against the spiral circular knife 2, the spiral circular knife 2 will generate heat. The temperature reduction component 8 injects water into the cavity 21 inside the spiral circular knife 2, thereby reducing the temperature rise of the spiral circular knife 2. And by driving the motor 88, the rotation directions of the spiral circular knife 2 and the spiral rod 85 are opposite, making the internal water flow better contact with the spiral circular knife 2.

[0044] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly.
