Description

Technical Field

[0001] This utility model relates to the field of plastic film production technology, specifically to a slitting machine for plastic film production. Background Technology

[0002] Plastic film production refers to the process of processing plastic raw materials into film products with specific thicknesses, widths, and properties through specific technological processes. This process is widely used in packaging, agriculture, industry, medicine, and many other fields, and is an indispensable part of modern industry.

[0003] An existing patent (publication number: CN219469224U) discloses a slitting machine for plastic film production, including a machine body. A first motor is bolted to the outer wall of one side of the machine body. A conveying roller is bolted to the first motor through its output end. A first cylinder and a second cylinder are bolted to the top of the machine body. The first cylinder is located next to the second cylinder, and a first lifting block is bolted to the first cylinder through its output end. A second lifting block is bolted to the second cylinder through its output end. This slitting machine for plastic film production allows for adaptive adjustment of the slitting width of the plastic film using slitting blades fitted on the slitting rollers. The blades are easily fixed by tightening a nut. The slitting blade position adjustment is simple and convenient, allowing for adaptive adjustment and broadening the machine's adaptability.

[0004] During use, the slitting machine described above can be adjusted according to the slitting width of the plastic film and can be easily fixed by tightening the fastening nut. The adjustment of the slitting blade position is simple and convenient and can be adjusted adaptively, making the slitting machine more adaptable. However, the slitting machine mainly uses bolts to fix the blades for adjusting the slitting blades, and the fixed hole position cannot be flexibly adjusted. Since the slitting blades are sleeved on the rotating spindle, excess slitting blades cannot be stored, which affects the cutting of the plastic film. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a slitting machine for plastic film production, which has the advantages of high adjustment precision and flexible adjustment, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slitting machine for plastic film production, comprising a machine body, an adjustment assembly inside the machine body, the adjustment assembly including multiple irregularly shaped parts, a limit rod fixedly connected to the inner wall of the machine body, a set of scale grooves on the outer surface of the limit rod, each irregularly shaped part being slidably sleeved with the limit rod, a rotating ring rotatably connected inside each irregularly shaped part, the bottom end of each rotating ring being convex, a slitting blade being provided at the bottom end of the convex end of each rotating ring, a concealed hole being provided on the left side of each slitting blade, an elastic limiting claw fixedly connected to the left side of each rotating ring, each elastic limiting claw engaging with its adjacent concealed hole, a sliding sleeve fixedly connected to the inner wall of the front end of each irregularly shaped part, each irregularly shaped part being connected to its adjacent sliding sleeve by a clamping bolt, and a tensioning assembly and an anti-wrinkle assembly being provided inside the machine body.

[0007] The above solution, by setting up adjustment components, enables precise adjustment of multiple slitting blades. With the help of scale grooves, workers can clearly and accurately observe the specific distance between each slitting blade.

[0008] Furthermore, the inner wall of the machine body is rotatably connected to an irregularly shaped column, which is slidably inserted into each rotating ring.

[0009] The above scheme allows the irregularly shaped column to rotate, causing each rotating ring to rotate. This rotation of each rotating ring then drives the slitting blade to adjust its angle, thereby allowing for adjustment of the cutting depth.

[0010] Furthermore, a limiting slide rod is fixedly connected to the inner wall of the machine body, and each sliding sleeve is slidably connected to the limiting slide rod. Each sliding sleeve is connected to the limiting slide rod by a clamping bolt.

[0011] The above scheme allows for the adjustment of the position of irregularly shaped parts by setting a limit slide bar and a sliding sleeve, and the position of the irregularly shaped parts can be locked by tightening bolts.

[0012] Furthermore, two tensioning rollers are rotatably connected to the inner wall of the machine body. The tensioning assembly includes a transport spindle, with sliding blocks rotatably connected to both ends of the transport spindle. Limiting frames are slidably sleeved on the bottom ends of the two sliding blocks. A set of springs is fixedly connected to the inner walls of the two limiting frames, and the other end of each spring is fixedly connected to the adjacent sliding block.

[0013] The above solution allows for the adjustment of the tension of the plastic film by setting up a tensioning component, ensuring that the plastic film is kept taut and facilitating subsequent slitting.

[0014] Furthermore, a collection frame is fixedly connected to the inner wall of the machine body, a collection box is inserted into the inside of the collection frame, and both limiting frames are fixedly connected to the collection frame.

[0015] The above solution allows for the collection of scraps generated during cutting, facilitating their unified processing by subsequent staff.

[0016] Furthermore, a baffle is installed on the front of the collection box, and a connecting pipe is fixedly connected to the front of the collection frame, the connecting pipe being fixedly connected to the output end of an external extraction device.

[0017] By using the above scheme, the combination of the connecting pipe and the baffle can allow the suction force of the external extraction device to be transmitted to the collection frame through the baffle, so that the collection frame can collect the scraps generated during cutting through suction.

[0018] Furthermore, a ratchet is fixedly connected to the left end of the irregular column, and a pawl is hinged to the left side of the machine body, with the ratchet in contact with the pawl.

[0019] The above scheme, which sets the pawl and ratchet in action, can limit the movement of the irregular column and prevent it from rotating during the slitting process, thus affecting the cutting quality of the plastic film.

[0020] Furthermore, a control device is installed on the right side of the machine body.

[0021] The above solution enables staff to control the overall operation of the equipment and record its status.

[0022] Furthermore, the anti-wrinkle assembly includes a rotating rod rotatably connected to the inner wall of the machine body. The left end of the rotating rod is fixedly connected to the output end of an external motor. Two symmetrical threaded grooves are formed on the outer surface of the rotating rod. Support frames are threadedly connected to the outer surfaces of the two threaded grooves. Tensioning cylinders are rotatably connected to the inner walls of the two support frames through one-way bearings.

[0023] The above solution allows for the adjustment of the plastic film at the front end of the slitting process, preventing wrinkles caused by tension.

[0024] Furthermore, each of the slitting blades is hinged to the inner wall of the protruding end of the adjacent rotating ring, and each of the slitting blades is capable of rotating and folding with respect to the adjacent rotating ring.

[0025] With the above solution, the rotating slitting blade fits snugly against the surface of the rotating ring, making it safer and preventing it from piercing the outside, thus avoiding accidental injury to workers.

[0026] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0027] This plastic film slitting machine, through the connection between the irregular part and the limiting slide rod, allows for unequal adjustment of the distance between each slitting blade by sliding the irregular part when adjusting its position. With the help of the scale groove, the operator can clearly and accurately observe the specific distance between each slitting blade, thus meeting the user's personalized production needs.

[0028] Secondly, the slitting blade has an adjustment function. The operator only needs to rotate the irregular column and drive the rotating ring and the slitting blade on the rotating ring to adjust the position, thereby adjusting the distance between the slitting blade and the film surface. The cutting depth can be flexibly adjusted according to actual needs. The operator can adjust the number of slitting blades used according to the number of films to be cut, and store and fold the idle slitting blades.

[0029] By setting a tensioning component, the tension of the plastic film can be adjusted. In conjunction with an anti-wrinkle component, the tension of the plastic film can be maintained while preventing wrinkles from appearing on its surface due to stretching, thereby ensuring the slitting quality of the plastic film.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Please see Figure 1 , Figure 2 and Figure 3 This embodiment describes a slitting machine for producing plastic film. The machine body 1 has an internal adjustment assembly 2, which includes multiple irregularly shaped parts 202. A limiting rod 203 is fixedly connected to the inner wall of the machine body 1. A set of graduated grooves 204 are formed on the outer surface of the limiting rod 203. Each irregularly shaped part 202 is slidably sleeved with the limiting rod 203. A rotating ring 205 is rotatably connected inside each irregularly shaped part 202. The bottom end of each rotating ring 205 is protruding, and a slitting blade 206 is provided at the protruding bottom end of each rotating ring 205. A hidden hole 207 is formed on the left side of each slitting blade 206. An elastic limiting claw 208 is fixedly connected to the left side of each rotating ring 205, and each elastic limiting claw 208 engages with its adjacent hidden hole 207. The inner wall of the front end of each irregularly shaped part 202... Each component 202 is fixedly connected to a sliding sleeve 209. Each irregularly shaped component 202 is connected to its adjacent sliding sleeve 209 by a clamping bolt. The machine body 1 is equipped with a tensioning component 14 and an anti-wrinkle component 15. By setting the adjustment component 2, the multiple slitting blades 206 can be precisely adjusted. With the help of the scale groove 204, the operator can clearly and accurately observe the specific distance between each slitting blade 206 to ensure that the spacing setting meets the production requirements. Secondly, the adjustment function of the slitting blade 206 provides great convenience for adjusting the cutting depth. The operator only needs to easily rotate the slitting blade 206 to flexibly adjust the cutting depth according to the actual needs. When the slitting blade 206 is adjusted to the correct position, the unused slitting blade 206 can be folded and stored to avoid the tool being idle and occupying space and interfering with the slitting work.

[0044] Please see Figure 1 , Figure 2 and Figure 3 The inner wall of the machine body 1 is rotatably connected to a shaped column 3, which is slidably inserted into each rotating ring 205. The shaped column 3 is designed to drive each rotating ring 205 to rotate during its rotation, thereby driving the slitting blade 206 to adjust its angle and thus adjust the cutting depth. The inner wall of the machine body 1 is fixedly connected to a limiting slide rod 201, and each sliding sleeve 209 is slidably connected to the limiting slide rod 201. Each sliding sleeve 209 is connected to the limiting slide rod 201 by a clamping bolt. By setting the cooperation between the limiting slide rod 201 and the sliding sleeve 209, the position of the shaped part 202 can be adjusted, and by cooperating with the clamping bolt, the position of the shaped part 2 can be locked.

[0045] Please see Figure 1 , Figure 2 and Figure 5 Two tensioning rollers 5 are rotatably connected to the inner wall of the machine body 1. The tensioning assembly 14 includes a transport main shaft 1401. Sliding blocks 1402 are rotatably connected to both ends of the transport main shaft 1401. Limiting frames 1403 are slidably sleeved at the bottom ends of the two sliding blocks 1402. A set of springs 1404 is fixedly connected to the inner wall of the two limiting frames 1403. The other end of each spring 1404 is fixedly connected to the adjacent sliding block 1402. By setting the tensioning assembly 14, the tension of the plastic film can be adjusted so that the plastic film can be kept in a taut state, which is convenient for subsequent cutting. A collection frame 7 is fixedly connected to the inner wall of the machine body 1. A collection box 8 is inserted into the inside of the collection frame 7. The two limiting frames 1403 are fixedly connected to the collection frame 7. The collection box 8 can collect the scraps generated during cutting, which is convenient for subsequent unified processing by the staff.

[0046] Please see Figure 1 , Figure 2 and Figure 4 A baffle 9 is installed on the front of the collection box 8, and a connecting pipe 10 is fixedly connected to the front of the collection frame 7. The connecting pipe 10 is fixedly connected to the output end of the external extraction device. The cooperation between the connecting pipe 10 and the baffle 9 allows the suction force of the external extraction device to be transmitted to the collection frame 7 through the baffle 9, so that the collection frame 7 can collect the scraps generated during cutting through suction. A ratchet 11 is fixedly connected to the left end of the irregular column 3, and a pawl 12 is hinged to the left side of the machine body 1. The ratchet 11 and the pawl 12 are in contact. The cooperation between the pawl 12 and the ratchet 11 can limit the irregular column 3 and prevent the irregular column 3 from rotating during the cutting process, which would affect the cutting quality of the plastic film. A control device 13 is installed on the right side of the machine body 1. The control device 13 allows the staff to control the operation of the entire equipment and record the working status.

[0047] Please see Figure 1 , Figure 4 and Figure 5 The anti-wrinkle assembly 15 includes a rotating rod 1501 rotatably connected to the inner wall of the machine body 1. The left end of the rotating rod 1501 is fixedly connected to the output end of an external motor. Two symmetrical threaded grooves 1502 are opened on the outer surface of the rotating rod 1501. Support frames 1503 are threadedly connected to the outer surfaces of the two threaded grooves 1502. The inner walls of the two support frames 1503 are rotatably connected to a tension cylinder 1504 through a one-way bearing. The anti-wrinkle assembly 15 can adjust the plastic film at the front end of the slitting operation to prevent the plastic film from wrinkling due to tension. Each slitting blade 206 is hinged to the inner wall of the protruding end of the adjacent rotating ring 205. Each slitting blade 206 can rotate and fold with the adjacent rotating ring 205. The rotating slitting blade 206 fits against the surface of the rotating ring 205, which is safer and will not insert into the outside, avoiding accidental injury to the staff.

[0048] In this embodiment, a slitting machine for plastic film production utilizes the connection between the shaped component 202 and the limiting slide rod 201. When adjusting the position of the shaped component 202, the distance between each slitting blade 206 can be adjusted unequally by sliding the shaped component 202. Combined with the scale groove 204, operators can clearly and accurately observe the specific distance between each slitting blade 206, meeting the user's personalized production needs. Furthermore, the slitting blades 206 have an adjustment function; operators only need to rotate the shaped column 3, which in turn drives the rotating ring 205 and the rotating ring 206. The position of the slitting blade 206 on the 5 is adjustable, which allows for adjustment of the distance between the slitting blade 206 and the film surface. The cutting depth can be flexibly adjusted according to actual needs. The number of slitting blades 206 used can be adjusted according to the number of films to be cut. The idle slitting blades 206 can be stored and folded. The tension component 14 can be set to adjust the tension of the plastic film. With the anti-wrinkle component, the tension of the plastic film can be maintained while preventing wrinkles from appearing on the surface of the plastic film due to stretching, thereby ensuring the slitting quality of the plastic film.

[0049] It should be noted that each elastic limiting claw 208 is integrally stamped from elastic steel, and the outer surfaces of both limiting frames are stamped with openings. When adjusting the height of the sliding block, the sliding block is limited by tightening bolts passing through the openings.

[0050] The working principle of the above embodiment is as follows: First, before operation, multiple irregularly shaped parts 2 are displaced, and the positions between them are adjusted according to production needs. This allows for flexible adjustment of the spacing between multiple slitting blades 206. After the spacing of the multiple slitting blades 206 is adjusted, when it is necessary to cut plastic films of different sizes simultaneously, the slitting blade 206 located in the middle of the wider plastic film is folded. This allows the wider plastic film to be cut during the slitting process. When irregular spacing adjustment is required, the clamping bolt is loosened, and the sliding sleeve 209 is slid on the limiting slide rod 201 to readjust each irregularly shaped part. The spacing between parts 202 is adjusted by tightening bolts to re-fix them together, thus completing the irregular spacing adjustment. The operator can fold away the unused slitting blade 206, allowing the other end of the elastic limiting claw 208 to engage with the concealed hole 207 of the slitting blade 206 after adjustment, thereby positioning the slitting blade 206. Then, the operator rotates the irregular-shaped column 3, causing multiple rotating rings 205 to rotate. During this rotation, the rotating rings 205 adjust the angle of the slitting blade 206, thus adjusting the cutting depth. After rotation, the irregular-shaped column 3 is held in place by the ratchet 1... 2. The ratchet 11 engages with the shaped column 3 to limit its movement, ensuring its stability and preventing rotation during the slitting process that could affect cutting quality. When slitting the plastic film, as the film passes the two tension rollers 5, the rotating rod 1501 rotates under the drive of an external motor, and through the threaded groove 1502, it moves the two support frames 1503 closer or further apart. When the two support frames 1503 move closer, the two stretching cylinders 1504 rotate; when the two support frames 1503 move further apart, the two stretching cylinders 1504 stop under the action of the one-way bearing and utilize their friction with the plastic film to... The plastic film is stretched to prevent wrinkles caused by tension. The plastic film is then conveyed to the transport spindle 1401. The tension of the plastic film can be adjusted by the cooperation of the spring and the transport spindle 1401 to facilitate subsequent slitting. During the slitting process, the external extraction device can transmit suction to the collection frame 7 through the connecting pipe 10, so that the collection frame 7 can extract the scraps generated during the cutting. The operator can then remove the scraps inside the collection box 8. During the slitting process, the operator can control the operation of the entire equipment through the control device 13, and at the same time, the operator can record the working status.
