Description

Technical Field

[0001] This application relates to the field of plastic sheet trimming technology, and in particular to a plastic sheet trimming device with burr removal and dust adhesion functions. Background Technology

[0002] With the widespread application of plastic film in packaging, agriculture, industry and other fields, plastic film cutting devices are key equipment in plastic film processing, and their performance directly affects product quality and production efficiency.

[0003] In related technologies, plastic sheets are prone to defects such as edge tearing and wavy deformation during forming processes such as stamping and stretching. Traditional edge cutting devices need to use mechanical tools to perform secondary cutting on the damaged edges.

[0004] However, this method has the following drawbacks: while cutting the edges of the plastic sheet, it also brings some problems, such as burrs and particulate dust generated during the cutting process. Burrs not only affect the appearance quality of the plastic sheet, but may also cause safety hazards during use, while particulate dust may pollute the production environment. Utility Model Content

[0005] To address the aforementioned issues, this application provides a plastic sheet trimming device with burr removal and dust adhesion functions.

[0006] The plastic sheet trimming device with burr removal and dust adhesion functions provided in this application adopts the following technical solution:

[0007] A plastic sheet edge cutting device with burr removal and dust adhesion functions includes a frame and a cutting assembly, and also includes an adhesion assembly. The adhesion assembly is disposed at the rear end of the cutting assembly. The adhesion assembly includes a support rod and an adhesive attachment. The support rod is slidably disposed on the frame. The adhesive attachment is sleeved on the outer wall of the support rod and is located between the plastic sheet cut by the cutting assembly and the edge piece generated after cutting. The adhesive attachment is in frictional contact with the plastic sheet and the edge piece.

[0008] By adopting the above technical solution, the adhesive attachment is sleeved on the outer wall of the support rod and rubs against the cut plastic sheet and the edge piece generated after cutting. The burrs can be removed in real time through physical friction. At the same time, it can adhere to particulate dust, reducing the impact of burrs on appearance quality and reducing the problem of particulate dust from cutting polluting the production environment. The sliding setting of the support rod on the frame can be dynamically adjusted according to the position between the plastic sheet and the edge piece, ensuring that the adhesive attachment can always maintain frictional contact with the plastic sheet and the edge piece.

[0009] Preferably, the adhesive attachment is made of gauze, which is wrapped around the outer wall of the support rod and in frictional contact with the plastic sheet and the edge piece.

[0010] By adopting the above technical solution, the gauze is woven from natural fibers and has the characteristics of being soft and porous. When rubbing against the edge of the plastic sheet, the fibers of the gauze gradually peel off the burrs generated during the cutting process through a tiny physical scraping action. The gauze is prone to generating static electricity during the friction process with the plastic sheet and the edge piece. By utilizing the electrostatic adhesion of the gauze fibers and the porous structure of the gauze to intercept dust particles, the problem of dust pollution from cutting is reduced.

[0011] Preferably, the support rod includes a rod body and a cylindrical block, the rod body is fixedly connected to the outer wall of the cylindrical block, and the cylindrical block is slidably disposed on the frame.

[0012] By adopting the above technical solution, the support rod is slidably set on the frame through the cylindrical block, which realizes the free movement of the support rod along the horizontal direction of the frame. It can be dynamically adjusted according to the position between the edge piece and the cut plastic piece after cutting, ensuring that the adhesive can always maintain frictional contact with the plastic piece and the edge piece.

[0013] Preferably, it also includes a fastening bolt, wherein a threaded hole is provided at the end of the cylindrical block away from the rod body, and the fastening bolt is screwed into the threaded hole and abuts against the frame.

[0014] By adopting the above technical solution, after the support rod slides to the target position, the fastening bolts are screwed into the threads and abut against the side wall of the frame. The other side wall of the frame abuts against the inner wall of the cylindrical block, which can quickly fix the cylindrical block to the frame and reduce the displacement of the support rod caused by external vibration or impact during the cutting of plastic sheet.

[0015] Preferably, the rod is fixedly connected to a limiting block, and the gauze is wrapped around the limiting block and the rod.

[0016] By adopting the above technical solution, the limiting block can provide adhesion conditions for the gauze through its own physical blocking effect, and provide longitudinal resistance for the gauze wrapped on the rod, reducing the gauze from slipping or loosening when subjected to external force.

[0017] Preferably, it further includes an auxiliary conveying assembly located at the front end of the cutting assembly. The auxiliary conveying assembly includes a support frame and an adjusting roller group. The adjusting roller group includes a first roller and a second roller. Both the first roller and the second roller are rotatably supported on the support frame, and the surfaces of the first roller and the second roller are in rolling contact with the plastic sheet.

[0018] By adopting the above technical solution, the auxiliary conveying component is located at the front end of the cutting component, and the support frame provides rigid support for the first roller and the second roller, ensuring that the plastic sheet is transported along a predetermined path at the front edge of the cutting component, reducing cutting deviations caused by the shaking or wrinkling of the plastic sheet.

[0019] Preferably, the auxiliary conveying assembly further includes a hinged rod, which is hinged to the support frame, and the first roller is rotatably supported on the hinged rod.

[0020] By adopting the above technical solution, the hinge rod is hinged to the support frame, thereby driving the vertical and lateral displacement of the first roller. This allows the distance between the first roller and the second roller to be adjusted according to the thickness of the plastic sheet, ensuring that the clamping force between the first roller and the second roller is adapted to different plastic sheet thicknesses, reducing the risk of material deformation due to excessive clamping or slippage due to excessive looseness.

[0021] Preferably, the auxiliary conveying assembly further includes a drive cylinder and a connecting block. The drive cylinder is hinged to the support frame and located above the hinge rod. The connecting block is hinged to the hinge rod. The piston rod of the drive cylinder is fixedly connected to the outer wall of the connecting block.

[0022] By adopting the above technical solution, the drive cylinder moves the connecting block through the piston rod, indirectly driving the hinge rod to swing, thereby dynamically adjusting the distance between the first roller and the second roller to adapt to plastic sheets of different thicknesses. At the same time, when the drive cylinder drives the first roller to move downward, the vertical distance between the second roller and the first roller decreases, and the horizontal distance increases, applying a lateral tension to the plastic sheet and keeping it in a taut state. When the first roller moves upward, the tension is released, ensuring that the probability of looseness or wrinkles in the plastic sheet is reduced before cutting.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By sliding the support rods set on the frame and attaching adhesive to the support rods, the adhesive is used to remove burrs and dust particles from the cut plastic sheets and edge pieces in real time through frictional contact with the cut plastic sheets and edge pieces. The support rods are dynamically adjusted to ensure frictional contact between the adhesive and the plastic sheets and edge pieces, thereby improving the appearance quality of the plastic sheets and the cleanliness of the production environment.

[0025] 2. The adhesive attachment is made of gauze. The soft and porous structure of the gauze enables micro-physical scraping to remove burrs. The gauze also attracts dust particles generated during cutting by electrostatic adsorption and the porous structure through friction between the gauze and the plastic sheet and its edge. This effectively improves the appearance quality of the plastic sheet and reduces environmental pollution.

[0026] 3. The limiting block is fixedly connected to the rod and wrapped with gauze. The longitudinal physical blocking effect of the limiting block provides resistance to the gauze, effectively reducing the gauze from slipping or loosening when subjected to external force, and ensuring that the adhesion component continues to perform its deburring and dust removal functions.

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a plastic sheet trimming device with burr removal and dust adhesion functions. (Refer to...) Figure 1A plastic sheet edge cutting device with burr removal and dust adhesion functions includes a frame 1, an auxiliary conveying component 2, a cutting component 3, and an adhesion component 4. The auxiliary conveying component 2, the cutting component 3, and the adhesion component 4 are all mounted on the frame 1. The auxiliary conveying component 2, the cutting component 3, and the adhesion component 4 are arranged at intervals along the processing direction of the plastic sheet. When the plastic sheet is conveyed into the plastic sheet edge cutting device with burr removal and dust adhesion functions, it is first guided by the auxiliary conveying component 2, then cut into finished plastic sheet and waste plastic sheet by the cutting component 3, and then deburred and treated with waste dust by the adhesion component 4 before being sent to the next process.

[0036] Reference Figure 2 Specifically, the frame 1 is rectangular and is mounted on the ground. The auxiliary conveying assembly 2 includes a support frame 21 and an adjusting roller assembly. The support frame 21 includes two frame bodies and two steps that are fixed parallel to each other on the frame 1. The adjusting roller assembly includes a first roller 22 and a second roller 23. The first roller 22 and the second roller 23 are both located between the two frame bodies. The second roller 23 is rotatably supported on the frame 1, and the first roller 22 is rotatably supported on the support frame 21. The surfaces of the first roller 22 and the second roller 23 are in rolling contact with the plastic sheet.

[0037] Reference Figure 3 Furthermore, the auxiliary conveying assembly 2 includes a drive cylinder 24, a connecting block 25, and a hinge rod 26. Two sets of each drive cylinder 24, connecting block 25, and hinge rod 26 are provided, located on opposite sides of the frame 1. The two sets of drive cylinders 24, connecting blocks 25, and hinge rods 26 act on the two ends of the first roller 22. Taking one set of drive cylinders 24, connecting blocks 25, and hinge rods 26 as an example, the drive cylinder 24 is hinged to the support frame 21 and located above the hinge rod 26. A hinge block 27 is provided between the connecting block 25 and the hinge rod 26. The connecting block 25 rotatably rests on the hinge block 27, while the side wall of the hinge block 27 is fixedly connected to the side wall of the hinge rod 26. The piston rod of the drive cylinder 24 is fixedly connected to the outer wall of the connecting block 25. Additionally, the side of the hinge rod 26 furthest from the adjusting roller group is hinged to the frame, and the other side of the hinge rod 26 is rotatably connected to both ends of the first roller 22.

[0038] The piston rod of the drive cylinder 24 drives the connecting block 25 to move, indirectly driving the hinge rod 26 to swing, thereby dynamically adjusting the distance between the first roller 22 and the second roller 23 to adapt to plastic sheets of different thicknesses. At the same time, when the drive cylinder 24 drives the first roller 22 to move downward, the vertical distance between the second roller 23 and the first roller 22 decreases and the horizontal distance increases, applying a lateral tension to the plastic sheet and keeping it in a taut state. When the first roller 22 moves upward, the tension is released, ensuring that the probability of looseness or wrinkles in the plastic sheet is reduced before cutting.

[0039] Reference Figure 4 In addition, a transmission assembly 5 is provided between the second roller 23 and the frame 1. The transmission assembly 5 is fixed on the frame 1. The second roller 23 rotates on the transmission assembly 5 and can be linearly displaced in the vertical direction by the transmission assembly 5.

[0040] Specifically, a shaft 7 is provided between the second roller 23 and the transmission assembly 5. The second roller 23 is rotatably connected to the shaft 7. A rotating block 71 is fixed on the side of the shaft 7 away from the second roller 23. The transmission assembly 5 includes a lead screw 51 and a handwheel 52. The rotating block 71 is threadedly engaged with the lead screw 51, and the handwheel 52 is coaxially fixed with the lead screw 51. When the handwheel 52 is rotated, it drives the lead screw 51 to rotate synchronously. When the lead screw 51 rotates, the interaction between the lead screw 51 and the rotating block 71 forms a threaded engagement, which causes the shaft 7 to reciprocate linearly along the axis of the lead screw 51. Since the second roller 23 is rotatably connected to the shaft 7, it also drives the second roller 23 to reciprocate linearly along the axis of the lead screw 51.

[0041] On the other hand, a third roller 6 is provided on the side of the cutting assembly 3 away from the auxiliary traction assembly. The third roller 6 is also rotatably supported on the transmission assembly 5. The cutting assembly 3 includes a machine cutter 31 and a drive motor 32. The machine cutter 3 is slidably mounted on the frame 1. The machine cutter 31 has a cutting channel inside. The plastic sheet enters the cutting channel through the auxiliary traction assembly. Rotating cutter discs 311 are provided at both ends of the cutting channel. The drive motor 32 drives the rotating cutter discs 311 to achieve high-speed and continuous cutting of the plastic sheet. The machine cutter 31 can be moved in the horizontal direction. The position of the machine cutter 31 can be adjusted according to the position of the plastic sheet.

[0042] Furthermore, since the first roller 22 and the second roller 23 can adjust the vertical displacement according to the thickness of the plastic sheet, the height of the plastic sheet can be further adjusted so that the plastic sheet comes into contact with the rotating cutter head 311, ensuring that the plastic sheet is successfully cut.

[0043] Reference Figure 5 In addition, the cut plastic and edge pieces are fed into the adhesion assembly 4 through the third roller 6. The adhesion assembly 4 is provided with two sets. The adhesion assembly 4 includes a support rod 41 and an adhesive attachment 42. The support rod 41 is slidably mounted on the frame 1. The adhesive attachment 42 is sleeved on the outer wall of the support rod 41 and is located between the plastic sheet cut by the cutting assembly 3 and the edge piece produced after cutting. The adhesive attachment 42 is in frictional contact with the plastic sheet and the edge piece.

[0044] This demonstrates that the adhesive attachment 42, sleeved on the outer wall of the support rod 41, rubs against the cut plastic sheet and the edge piece generated after cutting. It can remove burrs in real time through physical friction, and at the same time, it can adhere to particulate dust, reducing the impact of burrs on appearance quality and reducing the problem of particulate dust from cutting polluting the production environment. The sliding setting of the support rod 41 on the frame 1 can be dynamically adjusted according to the position between the plastic sheet and the edge piece, ensuring that the adhesive attachment 42 can always maintain frictional contact with the plastic sheet and the edge piece.

[0045] Furthermore, the adhesive attachment 42 is made of gauze, and the support rod 41 includes a rod body 411 and a cylindrical block 412. The cylindrical block 412 is fixedly connected to the rod body 411, and a limiting block 44 is fixed on the rod body 411. The gauze is wrapped around the limiting block 44. The limiting block 44 can provide longitudinal resistance to the gauze wrapped around the rod body 411 through its own physical blocking effect, reducing the gauze from slipping or loosening when subjected to external force.

[0046] This demonstrates that because the adhesive attachment 42 is made of gauze, which is woven from natural fibers and has soft and porous properties, when rubbing against the edge of the plastic sheet, the fibers of the gauze gradually peel off the burrs generated during the cutting process through a tiny physical scraping action. The gauze easily generates static electricity during the friction process with the plastic sheet and the edge piece. Utilizing the electrostatic adhesion of the gauze fibers and the porous structure of the gauze to trap dust particles reduces the problem of particulate dust pollution of the production environment caused by cutting.

[0047] Reference Figure 6 Furthermore, the cylindrical block 412 is slidably mounted on the frame 1 and fixed to the frame 1 by fastening bolts 43. The end of the cylindrical block 412 away from the rod 411 is provided with a threaded hole 4121. After the support rod 41 slides to the target position through the cylindrical block 412, the fastening bolt 43 is screwed into the threaded hole 4121 and abuts against the frame 1. After the support rod 41 slides to the target position, it is screwed into the thread by the fastening bolt 43 and abuts against the side wall of the frame 1. The other side wall of the frame 1 abuts against the inner wall of the cylindrical block 412. This allows the cylindrical block 412 to be quickly fixed to the frame 1, reducing the displacement of the support rod 41 caused by external vibration or impact during the cutting of the plastic sheet.

[0048] The implementation principle of the plastic sheet edge cutting device with burr removal and dust adhesion function in this application embodiment is as follows: The plastic sheet edge cutting device with burr removal and dust adhesion function includes a frame, an auxiliary conveying component, a cutting component and an adhesion component. The auxiliary conveying component, the cutting component and the adhesion component are all set on the frame, and the auxiliary conveying component, the cutting component and the adhesion component are arranged at intervals along the processing direction of the plastic sheet.

[0049] During the plastic sheet processing, the plastic sheet first enters the auxiliary conveying assembly, which includes a support frame, an adjusting roller group, a drive cylinder, a connecting block, a hinge rod, and a hinge block. The adjusting roller group includes a first roller and a second roller. The first roller and the second roller on the support frame achieve dynamic spacing adjustment through the coordinated work of the drive cylinder and the hinge rod to adapt to plastic sheets of different thicknesses.

[0050] The hinge rod is hinged to the support frame. The first roller rotates and is supported on the hinge rod, and the connecting block rotates and is supported on the hinge block. At the same time, the side wall of the hinge block is fixedly connected to the side wall of the hinge rod. The piston rod of the drive cylinder is fixedly connected to the outer wall of the connecting block. When the piston rod of the drive cylinder extends or retracts, it drives the connecting block to move, which in turn drives the hinge rod to swing, causing the first roller to move vertically. Meanwhile, the second roller is adjusted through the transmission assembly to achieve vertical displacement. The first roller and the second roller work together to apply lateral tension to the plastic sheet, ensuring that the plastic sheet remains taut before cutting and reducing slack or wrinkles.

[0051] A third roller is provided on the side of the cutting assembly away from the auxiliary conveying assembly. The third roller is also adjusted in the vertical direction by the transmission assembly.

[0052] The plastic sheet enters the cutting assembly, which includes a cutting machine and a drive motor. The cutting machine is equipped with a rotating cutter head. The plastic sheet is horizontally adjusted by the vertical displacement of the second and third rollers to ensure precise contact between the rotating cutter head and the edge of the plastic sheet. The drive motor drives the rotating cutter head to rotate at high speed, continuously cutting the plastic sheet and separating the finished product from the waste edge pieces. During the cutting process, the plastic sheet and the waste edge pieces are guided into the adhesion assembly by the third roller.

[0053] The adhesion assembly includes a support rod, fastening screws, adhesive attachments, and limiting blocks. The support rod comprises a rod body and a cylindrical block, and is slidably mounted on the frame. The support rod of the adhesion assembly slides to the target position via the cylindrical block and is fixed to the frame by the fastening screws. The adhesive attachment, sleeved on the outer wall of the support rod, makes close frictional contact with the cut plastic sheet and waste edge pieces. The adhesive attachment is made of gauze; the natural fibers of the gauze remove burrs generated by the cutting edges in real time through micro-physical scraping, improving the appearance quality of the plastic sheet. Simultaneously, the static electricity generated by the frictional contact between the gauze and the plastic sheet and edge pieces, along with the porous structure of the gauze, effectively reduces the impact of burrs on product quality and dust pollution to the production environment.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
