Description

Technical Field

[0001] This utility model belongs to the field of film production technology, and in particular relates to an edge guide roller device for a slitting machine in a biaxially stretched film production line. Background Technology

[0002] Biaxially stretched film is a type of plastic film produced through a biaxial stretching process. When biaxially stretched polyester film slitting machines are used for slitting, a guide roller device is required to pull the cut edge film to ensure stable tension of the film edge material and improve the slitting efficiency of the slitting machine.

[0003] Existing biaxially oriented polyester film slitting machines typically include two edge guide rollers, one on each side. The film is pulled by the two edge guide rollers, and the edge material is tightened by the edge winding machine, thus ensuring that the slitting machine can slit at high speed.

[0004] However, existing biaxially oriented polyester film slitting machines use side rollers fixed in a designated position and tensioned by the edge cutting machine. After abnormal edge breakage, the edge material will spring back, causing the side roller to wrap around itself. Furthermore, when disassembling the original side roller, the entire side roller needs to be removed, which is time-consuming and laborious. Therefore, a side roller structure that is easy to disassemble is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an edge guide roller device for a slitting machine in a biaxially stretched film production line, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an edge guide roller device for a slitting machine in a biaxially stretched film production line, comprising a cylinder, an adjustment component, an expansion component, and a positioning component. Two cylinders are symmetrically and parallelly arranged on a frame, and both ends of the two cylinders are symmetrically rotatably connected to insert blocks. The insert blocks are inserted parallel to grooves with openings on both sides inside a connecting block, and the connecting block is slidably disposed within the frame. The adjustment component is used to adjust the distance between the two cylinders. The expansion component is used to remove the film wrapped around the cylinder. The positioning component is used to position the insert blocks.

[0007] Beneficial effects This utility model provides an edge guide roller device for a slitting machine in a biaxially stretched film production line, which has the following advantages compared with the prior art: 1. When the roller is wrapped, the user can release the limit on the insert block by using the positioning component. At this time, the insert block can slide on its own in the connecting block. Then the user can apply a lateral pulling force to the cylinder to pull the connecting rod A at both ends out of the connecting block. Then the user can use the expansion component to clean the film covering it, so that the cylinder can be quickly disassembled. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1-5 This utility model provides an embodiment of an edge guide roller device for a slitting machine in a double-stretch film production line, comprising a cylinder 104, an adjustment component, an expansion component, and a positioning component. The two cylinders 104 are symmetrically and parallelly arranged on a frame 101, and both ends of the two cylinders 104 are symmetrically and rotatably connected to insert blocks 103. The insert blocks 103 are parallelly inserted into grooves with openings on both sides inside a connecting block 102, and the connecting block 102 is slidably arranged inside the frame 101. The adjustment component is used to adjust the distance between the two cylinders 104; the expansion component is used to remove the film wrapped on the cylinder 104; and the positioning component is used to position the insert block 103.

[0017] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific insert 103 and connecting block 102 described in the above embodiments. For example, both the insert 103 and connecting block 102 are made of high-hardness material. The purpose of this arrangement is to increase their load-bearing capacity.

[0018] In the above embodiment, when the roller is wrapped, the user releases the limit on the insertion block 103 by using the positioning component. At this time, the insertion block 103 can slide in the connecting block 102 by itself. Then the user can apply a lateral pulling force to the cylinder 104, thereby pulling the connecting rods A203 at both ends out of the connecting block 102. Then the user can clean the film covering it by using the expansion component, so that the cylinder 104 can be quickly disassembled.

[0019] Specifically, the adjustment assembly includes a bidirectional screw 105, two connecting blocks 102 are respectively threaded to both sides of the bidirectional screw 105, and the bidirectional screw 105 is rotatably connected to the frame 101. The other end of the bidirectional screw 105 is fixedly connected to the output shaft of the motor A106, and the motor A106 is fixedly connected to the frame 101.

[0020] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific motor A106 described in the above embodiments. For example, the motor A106 is selected as a motor with a self-locking effect. The purpose of this setting is to facilitate the increase of the limiting effect on the bidirectional screw 105 through this setting.

[0021] In the above embodiment, the user can start the motor A106, so that the bidirectional screw 105 fixedly connected to its output shaft starts to rotate at a constant speed. At this time, the two connecting blocks 102, which are threaded to its two ends, start to move linearly along the sliding connection between them and the frame 101, thereby increasing or decreasing the distance between the two cylinders 104, so as to facilitate the disassembly or installation of the insert 103.

[0022] Specifically, the positioning component includes a pressure plate 108, which is slidably disposed in a cavity on the upper surface of the connecting block 102, and the end of the pressure plate 108 penetrates into a groove on the upper surface of the insert block 103. A spring 201 is fixedly connected to the upper surface of the pressure plate 108, and the other end of the spring 201 is fixedly connected to the connecting block 102.

[0023] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific pressure plate 108 described in the above embodiments. For example, the outer wall of the pressure plate 108 is provided with a pressure block that passes through the connecting block 102. The purpose of this arrangement is to facilitate pressing the pressure plate 108 downward through this arrangement.

[0024] Specifically, a rod 107 is slidably connected to the insert block 103, and a damping rubber strip is provided at the connection between the rod 107 and the insert block 103. The end of the rod 107 is inserted into the cylinder 104 through a groove on the outer wall of the cylinder 104.

[0025] In the above embodiment, the user can lift the pressure plate 108 upwards to compress the spring 201 fixedly connected to it, so that the spring 201 can quickly push the pressure plate 108 back to its original position after the user stops lifting the pressure plate 108. During the process of lifting the pressure plate 108, the pressure plate 108 gradually disengages from the insert block 103, so that the pressure plate 108 stops limiting the insert block 103. At this time, the user can pull the insert block 103 out laterally from the connecting block 102, thus completing the disassembly of the cylinder 104. At the same time, during the disassembly process, the user should press down the insert rod 107 to insert it into the cylinder 104, thereby limiting the rotation of the cylinder 104 and preventing the cylinder 104 from rotating during the disassembly process.

[0026] Specifically, the expansion assembly includes a roller surface 202 and a support assembly. Multiple roller surfaces 202 are arranged around and fitted to the outer wall of the cylinder 104, and two adjacent roller surfaces 202 are seamlessly connected. A connecting rod B204 is hinged to one side of the roller surface 202, and the other end of the connecting rod B204 is disposed inside the cylinder 104. The support assembly is used to enable the multiple roller surfaces 202 to slide synchronously.

[0027] In the above embodiment, under the action of the support component, the multiple roller surfaces 202 begin to expand synchronously outward of the cylinder 104, thus pushing the film on them to stretch and deform. Since the film cannot quickly return to its original position after deformation, the user can use the support component again to reset the multiple roller surfaces 202 on the cylinder 104. At this time, there is a large gap between the film and the roller surface 202. The user can then remove the film along the length of the roller surface 202, thereby achieving rapid peeling of the film wrapped around the roller.

[0028] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific roller surface 202 described in the above embodiments. For example, the roller surface 202 is made of a high-hardness material. The purpose of this setting is to facilitate the increase of the limiting effect of the roller surface 202 on the film between them.

[0029] Specifically, the support assembly includes a connecting rod A203 and a drive assembly. One end of the connecting rod A203 is hinged to the cylinder 104, and the other end of the connecting rod A203 is hinged to the slider 207. The slider 207 is laterally slidably disposed on the inner arc surface of the roller surface 202 corresponding to it. The connecting rod A203 and the connecting rod B204 are rotatably connected to each other. The driving component is used to make the slider 207 slide at a constant speed.

[0030] Specifically, the drive assembly includes a lead screw 206, which is rotatably connected to the cylinder 104. A sliding sleeve 205 is threaded onto the lead screw 206, and the sliding sleeve 205 is hinged to multiple connecting rods B204. The other end of the lead screw 206 is fixedly connected to the output shaft of a motor 208, which is fixedly connected inside the cylinder 104 and has a self-locking effect.

[0031] In the above embodiment, the user can start the motor 208, which causes the lead screw 206 fixedly connected to its output shaft to rotate at a constant speed. At this time, the sliding sleeve 205 threaded on it begins to move linearly. That is, the sliding sleeve 205 begins to push the multiple connecting rods B204 hinged on it. Since the slider 207 hinged at the end of the connecting rod A203 is slidably set on the inner wall of the roller surface 202, the slider 207 begins to move linearly along its connection with the roller surface 202, thereby causing the multiple roller surfaces 202 to expand outward or converge inward synchronously.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0034] (1) Detachable connection: Components are fixed together using screws, splines, wedges, etc. This type of connection allows for disassembly during maintenance without damaging the parts. However, the specifications of the connectors used must be correct. (Such as the length of bolts, keys, and wedges), and tighten them properly.

[0035] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, during connection, [the following should be noted:] Pay attention to process quality, technical testing, and remedial measures (such as correction, polishing, etc.).

[0036] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0037] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
