Abstract
Description
Technical Field
[0001] This utility model relates to the field of pearl cotton trimming and slitting technology, specifically an EPE pearl cotton trimming and slitting machine. Background Technology
[0002] EPE pearl cotton, also known as polyethylene foam, is a new type of environmentally friendly packaging material. During its production process, burrs or unevenness may appear on the edges of pearl cotton. By trimming and slitting, these burrs can be removed, making the product edges smoother and cleaner, thereby improving the overall appearance quality of the product.
[0003] The existing EPE foam trimming and slitting device mainly consists of a frame, a conveying system, trimming blades, slitting blades, a drive system, and a control system. When trimming and slitting EPE foam, the material to be processed is first placed on the conveying system. Driven by the conveying system, the material is smoothly fed into the device. When the EPE foam material enters the trimming area, the trimming blades begin to work, trimming the edges of the EPE foam. After trimming, the EPE foam material continues to move forward into the slitting area, where the slitting blades cut the EPE foam. The cut EPE foam material then moves forward as needed into the cutting area, where it is cut into strips for subsequent packaging and processing.
[0004] Existing EPE foam trimming and slitting devices cannot quickly separate the trimmed scraps from the EPE foam during trimming and slitting. This causes the EPE foam to continue moving along with the cut EPE foam, preventing rapid separation. Furthermore, the trimmed scraps accumulate around the EPE foam trimming and slitting machine, making cleaning inconvenient and affecting its operation. Therefore, an EPE foam trimming and slitting machine is proposed to address these issues. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes an EPE pearl cotton trimming and slitting machine.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An EPE pearl cotton trimming and slitting machine of this utility model includes a worktable. A conveying mechanism, a trimming mechanism, a slitting mechanism, and a cutting mechanism are sequentially arranged on the worktable. The trimming mechanism includes two vertical plates. Two vertical plates are fixedly connected to the worktable. Each of the two vertical plates has a first sliding groove. A first lifting block is arranged in each of the two first sliding grooves. A first pneumatic cylinder is fixedly connected to the top of each of the two vertical plates. A first pneumatic rod is mounted on the actuating end of each of the two first pneumatic cylinders, and the bottom end of the first pneumatic rod is fixedly connected to the first lifting block. A bidirectional lead screw is rotatably mounted on each of the two first lifting blocks. A first electric motor is mounted on one of the first lifting blocks. The output end of the first motor is connected to one end of the bidirectional lead screw. Both ends of the bidirectional lead screw are fitted with movable blocks, and the bottom ends of the two movable blocks are equipped with trimming blades. A guide rod is fixed between the two first lifting blocks, and the guide rod passes through the movable blocks. When the pearl cotton is conveyed to the trimming area, the first motor is started, causing the bidirectional lead screw to rotate. With the cooperation of the guide rod, the two movable blocks drive the two trimming blades to move closer to each other until the two trimming blades move to the position where the pearl cotton needs to be trimmed. Then, the first pneumatic cylinder is started, causing the first lifting block to drive the trimming blades down until the trimming blades move down into the pearl cotton. When the pearl cotton passes under the trimming blades, the trimming operation of the pearl cotton edge can be achieved.
[0007] Preferably, a dust collection hood is fixedly connected to the bottom end of each of the two vertical plates, and a support frame is fixedly connected to the bottom side of the workbench. A waste collection box is installed on the support frame. Dust collection pipes are connected between the two sides of the waste collection box and the corresponding dust collection hoods. A rotating rod is rotatably installed inside each of the two dust collection hoods, and a spiral crushing blade is fixed to the outer surface of the rotating rod. A first motor is installed on one side wall of each of the two dust collection hoods, and the output end of the first motor is connected to one end of the rotating rod. A negative pressure pump is installed on the waste collection box. The input port of the negative pressure pump is connected to an air extraction pipe, and the other end of the air extraction pipe is located inside the waste collection box. The output port of the negative pressure pump is connected to an exhaust pipe. A filter screen is installed inside the waste collection box, and the filter screen surrounds the exhaust pipe. The air pipe port is designed to prevent the trimmed scraps from quickly separating from the pearl cotton and to avoid accumulation. A negative pressure pump is activated, drawing gas from the waste collection box through the suction pipe and venting it through the exhaust pipe, creating a negative pressure environment inside the waste collection box. This allows for timely cleaning and collection of the trimmed scraps, preventing accumulation and ensuring smooth subsequent trimming and cutting operations. To prevent blockage of the dust collection pipe, the first motor is activated, rotating the spiral crusher blades to crush the trimmed scraps, preventing blockage and ensuring smooth cleaning and dust collection operations.
[0008] Preferably, a discharge port is provided on one side wall of the waste collection box, and limit slide rails are fixedly connected to both the upper and lower sides of the discharge port. The two limit slide rails are fitted with a sealing cover plate. When using the device, the discharge port facilitates the removal of scraps collected in the waste collection box.
[0009] Preferably, the slitting mechanism includes two upright plates, each with a second sliding groove. A second lifting block is installed in each of the two second sliding grooves. A second pneumatic cylinder is mounted at the top of each of the two upright plates. A second pneumatic rod is fitted to the actuating end of each of the two second pneumatic cylinders. The bottom ends of each of the two second pneumatic rods are fixed to the second lifting block. A rotating column is rotatably mounted on each of the two second lifting blocks. Multiple slitting blades are mounted on the rotating column. A second electric motor is mounted on one of the second lifting blocks. The output end of the second electric motor is connected to one end of the rotating column. When the trimmed pearl cotton continues to be conveyed to the slitting area, the second pneumatic cylinder is activated, causing the second lifting block to move the slitting blade down to contact the pearl cotton. When the pearl cotton passes under the slitting blade, the slitting operation of the pearl cotton is achieved.
[0010] Preferably, the cutting mechanism includes a first fixed frame, which is fixedly connected to one side of the top of the workbench. Two third pneumatic cylinders are installed on the top side of the first fixed frame. The working ends of the two third pneumatic cylinders are equipped with third pneumatic rods, and the bottom ends of the two third pneumatic rods are fitted with cutting blades. When the slit pearl cotton continues to be conveyed to the cutting area, the third pneumatic cylinders are activated to move the cutting blades down, thereby cutting the slit pearl cotton, which facilitates subsequent packaging, processing and other operations.
[0011] Preferably, the conveying mechanism includes a second fixed frame. The second fixed frame is fixedly connected to the other side of the top of the workbench. Two limiting grooves are opened on both side walls of the second fixed frame. Each limiting groove is provided with a limiting block. An installation frame is fixedly connected between the two limiting blocks. A sanding conveying roller is installed in the installation frame through a rotating shaft. A second motor is mounted on one side wall of the installation frame. The output end of the second motor is connected to one end of the rotating shaft. A fourth pneumatic cylinder is installed on the top side of the second fixed frame. A fourth pneumatic rod is mounted on the working end of the fourth pneumatic cylinder, and the bottom end of the fourth pneumatic rod is fixedly connected to the installation frame. When conveying pearl cotton, the fourth pneumatic cylinder is activated to make the installation frame and the sanding conveying roller move down stably until the sanding conveying roller moves down to contact the surface of the pearl cotton. The second motor is activated to make the sanding conveying roller rotate. The rotating sanding conveying roller can drive the pearl cotton to move by friction, thereby realizing the automatic conveying of pearl cotton and facilitating subsequent automatic trimming and cutting operations.
[0012] Preferably, the top side of the workbench has four limiting grooves, and two limiting grooves on the same side are fitted with U-shaped movable frames. The top of each of the two U-shaped movable frames is fixedly connected to a limiting plate. The bottom side of the workbench is fixedly connected to two fixing blocks, and a bidirectional threaded rod is rotatably mounted on each of the two fixing blocks. The bidirectional threaded rod passes through the U-shaped movable frames. A third motor is mounted on one of the fixing blocks, and the output end of the third motor is connected to one end of the bidirectional threaded rod. When conveying the pearl cotton, in order to prevent the pearl cotton from shifting during the conveying process, a limiting mechanism is set up. When the third motor is started, the bidirectional threaded rod rotates, which causes the two U-shaped movable frames to move the two limiting plates closer together until the two limiting plates move to contact the two sides of the pearl cotton. Then the third motor stops working, thereby effectively limiting and fixing the pearl cotton, preventing the pearl cotton from shifting during the conveying process, and ensuring that the pearl cotton moves stably and straight along the preset trajectory.
[0013] The advantages of this utility model are:
[0014] 1. To prevent the trimmed scraps from quickly separating from the pearl cotton and to prevent accumulation, this utility model activates a negative pressure pump. This pump extracts gas from the waste collection box through the suction pipe and discharges it through the exhaust pipe, creating a negative pressure environment inside the waste collection box. This allows the trimmed scraps to be sucked into the waste collection box, enabling timely cleaning and collection of the scraps and preventing accumulation. This ensures the smooth progress of subsequent trimming and cutting operations. To prevent blockage of the dust collection pipe, the first motor is activated, causing the spiral crushing blades to rotate. This crushes the trimmed scraps, preventing blockage of the dust collection pipe and ensuring smooth cleaning and dust collection operations.
[0015] 2. In order to prevent the pearl cotton from shifting during the conveying process, this utility model sets up a limiting mechanism. The third motor is started, and the bidirectional threaded rod rotates, which causes the two U-shaped movable frames to drive the two limiting plates to move closer to each other until the two limiting plates move to contact the two sides of the pearl cotton. Then the third motor stops working, thereby effectively limiting and fixing the pearl cotton and preventing the pearl cotton from shifting during the conveying process. This ensures that the pearl cotton moves stably and straight along the preset trajectory. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 As shown, an EPE pearl cotton trimming and slitting machine includes a worktable 1. A conveying mechanism, trimming mechanism, slitting mechanism, and cutting mechanism are sequentially arranged on the worktable 1. The trimming mechanism includes two vertical plates 2. Two vertical plates 2 are fixedly connected to the worktable 1. Each vertical plate 2 has a first sliding groove 3. A first lifting block 4 is installed in each of the two first sliding grooves 3. A first pneumatic cylinder 5 is fixedly connected to the top of each of the two vertical plates 2. A first pneumatic rod is mounted on the actuating end of each of the two first pneumatic cylinders 5, and the bottom end of the first pneumatic rod is fixedly connected to the first lifting block 4. A bidirectional lead screw 6 is rotatably mounted on each of the two first lifting blocks 4. A first motor 7 is mounted on one of the first lifting blocks 4. The output end of the first motor 7 is connected to one end of the bidirectional lead screw 6. Movable blocks 8 are sleeved on both ends of the bidirectional lead screw 6. Trimming blades 9 are mounted on the bottom ends of both movable blocks 8. A guide rod 10 is fixedly connected between the two first lifting blocks 4. The guide rod 10 passes through the movable block 8. Dust hoods 11 are fixed to the bottom of the two vertical plates 2. A support frame 12 is fixed to the bottom side of the workbench 1. A waste collection box 13 is installed on the support frame 12. Dust collection pipes 14 are connected between the two sides of the waste collection box 13 and the corresponding dust hoods 11. When working, when the pearl cotton is transported to the trimming area, the trimming mechanism starts to work. First, the first motor 7 is started, which makes the bidirectional lead screw 6 rotate. With the cooperation of the guide rod 10, the two movable blocks 8 drive the two trimming blades 9 to move closer to each other until the two trimming blades 9 move to the position where the pearl cotton needs to be trimmed. The first motor 7 stops working. Then, the first pneumatic cylinder 5 is started, which makes the first pneumatic rod drive the first lifting block 4 to move down, and then the trimming blades 9 also move down until the trimming blades 9 move down into the pearl cotton. When the pearl cotton passes under the trimming blades 9, the trimming operation of the pearl cotton edge can be realized.
[0026] Both dust collection hoods 11 have rotating rods installed inside, and spiral crushing blades 15 are fixed to the outer surface of the rotating rods. A first motor 16 is installed on one side wall of each of the two dust collection hoods 11, and the output end of the first motor 16 is connected to one end of the rotating rod. A negative pressure pump 17 is installed on the waste collection box 13. The input port of the negative pressure pump 17 is connected to a suction pipe 18, and the other end of the suction pipe 18 is located inside the waste collection box 13. The output port of the negative pressure pump 17 is connected to an exhaust pipe 19. A filter screen is installed inside the waste collection box 13, and the filter screen surrounds the port of the suction pipe 18. A waste discharge port is opened on one side wall of the waste collection box 13. Limiting slide rails 20 are fixed to both the upper and lower sides of the waste discharge port. A sealing cover 21 is slidably fitted onto the two limiting slide rails 20 during operation. During operation, to avoid… The trimmed scraps are quickly separated from the pearl cotton without accumulation. The negative pressure pump 17 is started, which extracts the gas in the waste collection box 13 through the suction pipe 18 and discharges it through the exhaust pipe 19, creating a negative pressure state inside the waste collection box 13. This allows the trimmed scraps to be sucked into the waste collection box 13 through the dust suction pipe 14, thus enabling timely cleaning and collection of the trimmed scraps and preventing accumulation. This ensures the smooth progress of subsequent trimming and cutting operations. To prevent the dust suction pipe 14 from becoming blocked, the first motor 16 is started, which rotates the spiral crushing blade 15 to crush the trimmed scraps, preventing blockage of the dust suction pipe 14 and ensuring the smooth progress of cleaning and dust collection operations.
[0027] Please see Figure 5 As shown, the slitting mechanism includes two upright plates 22, each with a second sliding groove 23. A second lifting block 24 is installed within each of the two second sliding grooves 23. A second pneumatic cylinder 25 is mounted at the top of each of the two upright plates 22. A second pneumatic rod is fitted to the actuating end of each of the two second pneumatic cylinders 25. The bottom ends of each of the two second pneumatic rods are fixed to the second lifting block 24. A rotating column 26 is rotatably mounted on each of the two second lifting blocks 24. Multiple slitting blades 27 are mounted on the rotating column 26, one of which... The second lifting block 24 is equipped with a second motor 28, and the output end of the second motor 28 is connected to one end of the rotating column 26. During operation, when the trimmed pearl cotton continues to be conveyed to the slitting area, the slitting mechanism starts to work, and the second pneumatic cylinder 25 is activated, so that the second pneumatic rod drives the second lifting block 24 to move down, and then the slitting blade 27 also moves down until the slitting blade 27 moves down to contact the pearl cotton. When the pearl cotton passes under the slitting blade 27, the pearl cotton can be slitting.
[0028] The cutting mechanism includes a first fixed frame 29, which is fixed to one side of the top of the workbench 1. Two third pneumatic cylinders 30 are installed on the top side of the first fixed frame 29. The working end of each of the two third pneumatic cylinders 30 is equipped with a third pneumatic rod, and the bottom end of each of the two third pneumatic rods is fitted with a cutting blade 31. During operation, when the slit pearl cotton continues to be conveyed to the cutting area, the cutting mechanism starts to work, and the third pneumatic cylinders 30 are activated, causing the third pneumatic rods to drive the cutting blade 31 to move down, thereby cutting the slit pearl cotton, which is convenient for subsequent packaging, processing and other operations.
[0029] Please see Figure 1 and Figure 6 As shown, the conveying mechanism includes a second fixed frame 32. The second fixed frame 32 is fixedly connected to the other side of the top of the worktable 1. Two limiting grooves 33 are formed on both side walls of the second fixed frame 32. Limiting blocks 34 are provided in each of the two limiting grooves 33. A mounting frame 35 is fixedly connected between the two limiting blocks 34. A sanding conveying roller 36 is mounted in the mounting frame 35 via a rotating shaft. A second motor is mounted on one side wall of the mounting frame 35, and the output end of the second motor is connected to one end of the rotating shaft. A fourth pneumatic cylinder 37 is mounted on the top side of the second fixed frame 32. A fourth pneumatic rod is mounted on the actuating end of the fourth pneumatic cylinder 37, and the fourth pneumatic rod... The bottom end is fixed to the mounting frame 35. During operation, after the distance between the two limit plates 40 is adjusted, when conveying the pearl cotton, the fourth pneumatic cylinder 37 is started. With the cooperation of the limit groove 33 and the limit block 34, the fourth pneumatic rod drives the mounting frame 35 and the sanding conveying roller 36 to move down steadily until the sanding conveying roller 36 moves down to contact the surface of the pearl cotton. The fourth pneumatic cylinder 37 stops working and the second motor is started to make the sanding conveying roller 36 rotate. The rotating sanding conveying roller 36 can drive the pearl cotton to move by friction, thereby realizing the automatic conveying of the pearl cotton, which is convenient for subsequent automatic trimming and cutting operations.
[0030] Four limiting grooves 38 are provided on the top side of the workbench 1. Two limiting grooves 38 on the same side are fitted with U-shaped movable frames 39. The top of each of the two U-shaped movable frames 39 is fixedly connected to a limiting plate 40. Two fixing blocks 41 are fixedly connected to the bottom side of the workbench 1. Two bidirectional threaded rods 42 are rotatably mounted on the two fixing blocks 41 and pass through the U-shaped movable frames 39. A third motor 43 is mounted on one of the fixing blocks 41, and the output end of the third motor 43 is connected to one end of the bidirectional threaded rod 42. During operation, when conveying pearl cotton, in order to avoid the pearl cotton... If the cotton deviates during the conveying process, a limiting mechanism is set up, the third motor 43 is started, the bidirectional threaded rod 42 rotates, and the two U-shaped movable frames 39 move within the limiting slide 38 and move closer to each other. This causes the two U-shaped movable frames 39 to drive the two limiting plates 40 to move closer to each other until the two limiting plates 40 move to contact the two sides of the pearl cotton. Then the third motor 43 stops working, thus effectively limiting and fixing the pearl cotton, preventing the pearl cotton from deviating in position during the conveying process, and ensuring that the pearl cotton moves stably and straight along the preset trajectory.
[0031] Working Principle: Existing EPE foam trimming and slitting devices cannot quickly separate the trimmed scraps from the EPE foam during trimming and slitting. This causes the EPE foam to continue moving along with the cut pieces, hindering rapid separation. Furthermore, the trimmed scraps accumulate around the trimming and slitting machine, making cleaning difficult and affecting its operation. Therefore, this EPE foam trimming and slitting machine is proposed to address these issues. Before trimming and slitting, the EPE foam needs to be conveyed. To prevent deviation during conveying, a limiting mechanism is used. The third motor 43 is activated, causing the bidirectional threaded rod 42 to rotate. This causes the two U-shaped movable frames 39 to move within the limiting groove 38 and move closer together. The two U-shaped movable frames 39 then drive the two limiting plates 40. The two limit plates 40 move closer together until they contact the sides of the pearl cotton. Then, the third motor 43 stops working, which effectively limits and fixes the pearl cotton, preventing it from shifting during transport and ensuring that it moves steadily and straight along the preset trajectory. After the distance between the two limit plates 40 is adjusted, the fourth pneumatic cylinder 37 is started when the pearl cotton is being transported. With the cooperation of the limit groove 33 and the limit block 34, the fourth pneumatic rod drives the mounting frame 35 and the sanding conveyor roller 36 to move steadily downward until the sanding conveyor roller 36 contacts the surface of the pearl cotton. The fourth pneumatic cylinder 37 stops working, and the second motor is started to make the sanding conveyor roller 36 rotate. The rotating sanding conveyor roller 36 can drive the pearl cotton to move by friction, thus realizing the automatic transport of the pearl cotton and facilitating subsequent automatic trimming and cutting operations.
[0032] When the pearl cotton is conveyed to the trimming area, the trimming mechanism begins operation. First, the first motor 7 is started, causing the bidirectional lead screw 6 to rotate. With the cooperation of the guide rod 10, the two movable blocks 8 drive the two trimming blades 9 to move closer to each other until the two trimming blades 9 move to the position where the pearl cotton needs trimming. The first motor 7 then stops operating. Next, the first pneumatic cylinder 5 is started, causing the first pneumatic rod to move the first lifting block 4 downward, which in turn moves the trimming blades 9 downward until they are inside the pearl cotton. When the pearl cotton passes under the trimming blades 9, the edge trimming operation of the pearl cotton is achieved. To prevent the trimmed scraps from quickly separating from the pearl cotton and to prevent accumulation, the starting of the negative... Pump 17 draws gas from the waste collection box 13 through the suction pipe 18 and discharges it through the exhaust pipe 19, creating a negative pressure inside the waste collection box 13. This allows the trimmed scraps to be sucked into the waste collection box 13 through the dust suction pipe 14, enabling timely cleaning and collection of the trimmed scraps and preventing accumulation. This ensures the smooth progress of subsequent trimming and cutting operations. To prevent blockage of the dust suction pipe 14, the first motor 16 is started, causing the spiral crushing blades 15 to rotate. This crushes the trimmed scraps, preventing blockage of the dust suction pipe 14 and ensuring smooth cleaning and dust collection operations.
