Description

Technical Field

[0001] This utility model belongs to the field of slitting machine technology, and in particular relates to a slitting machine and a slitting machine for preventing scratches on finished film rolls. Background Technology

[0002] A slitting machine is a device that longitudinally cuts wide materials (such as paper, plastic, film, metal foil, etc.) into multiple narrow strips and winds them into finished film rolls. To eliminate static electricity carried by the finished film rolls, static eliminators are usually installed on the rolls and mounted on the steel wire rope of the slitting machine. However, under prolonged use, the steel wire rope is prone to deformation, i.e., sagging. This causes the static eliminator to become too close to the finished film roll, resulting in scratches on the roll. This paper proposes a structure that can prevent scratches on the finished film rolls during slitting. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a scratch-resistant structure for finished film rolls in a slitting machine and a slitting machine in general, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a scratch-resistant structure for finished film rolls in a slitting machine and a slitting machine, comprising a support frame, the support frame being horizontally positioned beside the slitting machine, a top rod being vertically positioned above the support frame, and two symmetrically positioned limiting blocks being vertically positioned on the side of the upper end of the top rod, with each limiting block being fixedly connected to the side of the top rod, and each of the two limiting blocks having symmetrically positioned through holes, which together form a complete circular hole after the two limiting blocks are fitted together, with the diameter of the circular hole being smaller than the diameter of the steel wire rope, and bolts A for fastening the two limiting blocks being horizontally and symmetrically positioned on the sides of the two limiting blocks.

[0005] Beneficial effects

[0006] This utility model provides a scratch-resistant structure for finished film rolls in a slitting machine and a slitting machine in general, which has the following advantages compared with the prior art:

[0007] 1. When it is necessary to fix the steel wire rope used to install the anti-static device on the slitting machine, the user should place the limiting block close to the steel wire rope and make the steel wire rope inside the through hole. At this time, the user can press the other limiting block until it fits against the through hole. Then, the through holes on the two limiting blocks can fit against the steel wire rope. Since the diameter of the through hole is smaller than the diameter of the steel wire rope, the sides of the two limiting blocks that are close to each other cannot fit tightly together. Then, the user inserts the disc into the through hole of the limiting block and tightens the bolt on its end, thereby giving the two limiting blocks a preload force, so that the two limiting blocks cooperate to position the steel wire rope. At this time, the steel wire rope is relatively fixed at the upper end of the bracket, thereby supporting the steel wire rope through the bracket and effectively preventing it from deforming and sagging after long-term use.

[0013] 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.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1-4This invention provides an embodiment of a slitting machine for preventing scratches on finished film rolls, and a slitting machine itself. The slitting machine includes a support 101, which is horizontally positioned beside the slitting machine. A top rod 201 is vertically positioned above the support 101. Two symmetrically positioned limiting blocks 202 are vertically arranged on the side of the upper end of the top rod 201, with each limiting block 202 fixedly connected to the side of the top rod 201. Each limiting block 202 has symmetrically positioned through holes 203, which form a complete circular hole when the two limiting blocks 202 are fitted together. The diameter of the circular hole is small. Regarding the diameter of the wire rope; both ends of the bracket 101 should be horizontally welded to the slitting machine, and the welding position should ensure that the upper end of the top rod 201 can contact the wire rope, and avoid affecting the normal operation of the slitting machine; or the bracket 101 can be fixed to the ground on the side of the slitting machine with expansion bolts; the user can flexibly choose the above two fixing methods according to the specific situation; at the same time, the bracket 101 can be equipped with multiple top rods 201 for supporting the wire rope, and any static elimination device hoisted on the wire rope is located between two adjacent top rods 201; and the wire rope should be in a horizontally taut state when the static elimination device is hoisted.

[0016] Specifically, two limiting blocks 202 are horizontally and symmetrically provided with bolts A207 on their sides, and the bolts A207 pass through the two limiting blocks 202 through the through holes on the limiting blocks 202, and the ends of the bolts A207 that pass through the limiting blocks 202 are threaded with nuts.

[0017] In the above embodiment, when it is necessary to fix the steel wire rope used to install the anti-static device on the slitting machine, the user should place the limiting block 202 close to the steel wire rope and make the steel wire rope inside the through hole 203. At this time, the user can press the other limiting block 202 until it fits against the through hole 203. Then, the through holes 203 on the two limiting blocks 202 can fit against the steel wire rope. Since the diameter of the through hole 203 is smaller than the diameter of the steel wire rope, the sides of the two limiting blocks 202 that are close to each other cannot fit tightly against each other. Then, the user inserts the disc 205 into the through hole of the limiting block 202 and tightens the bolt on its end, thereby giving the two limiting blocks 202 a preload force, so that the two limiting blocks 202 cooperate with each other to position the steel wire rope. That is, at this time, the steel wire rope is relatively fixed at the upper end of the bracket 101, thereby supporting the steel wire rope through the bracket 101, effectively preventing it from deforming and sagging after long-term use.

[0018] Specifically, the limiting block 202 is provided with a clamping component for clamping the wire rope on its side. The clamping component includes a bolt 204, which is horizontally disposed at the upper end of the top rod 201 and threadedly connected to the top rod 201. The end of the bolt 204 faces the wire rope and is on the same horizontal plane as the wire rope.

[0019] Specifically, a disc 205 is coaxially fixedly connected to the end of the bolt 204 near the end of the wire rope. The upper end of the disc 205 is horizontally slidably mounted on the bracket 101, and the diameter of the disc 205 is larger than the diameter of the wire rope.

[0020] Specifically, the disc 205 has multiple limiting strips 206 horizontally fixedly connected to the side near the wire rope, and the wire rope is positioned between the multiple limiting strips 206.

[0021] In the above embodiment, after the wire rope is clamped and fixed by the limiting block 202, the wire rope is aligned with the axis of the disc 205. At this time, the user can rotate the bolt 204, causing the disc 205 to begin horizontal linear movement. That is, the disc 205 begins to push the limiting strip 206, causing it to lock onto the wire rope. The bolt 204 is then tightened until it cannot be rotated. Thus, while the wire rope is clamped by the limiting block 202, the disc 205 applies a lateral thrust to the wire rope, thereby further supporting the wire rope and effectively preventing displacement of the wire rope through the limiting strip 206.

[0022] Specifically, the bracket 101 is provided with an adjustment component for adjusting the support height of the top rod 201. The adjustment component includes a plug 208, a plurality of plugs 208 are fixedly connected to each other and are vertically arranged on the upper surface of the bracket 101. A slot 209 is horizontally arranged in the plug 208, and the lower end of the top rod 201 is horizontally inserted into the slot 209.

[0023] In the above embodiment, if the steel wire rope continues to descend after the support 101 has supported it for a long time, the user can manually hold the top rod 201 and pull the lower end of the top rod 201 out of its corresponding slot 209, and then immediately insert it into the upper slot 209. During the process of moving the slot 209, the top rod 201 is prevented from sliding downward. This increases the height of the top rod 201 to prevent the steel wire rope from sagging and causing the antistatic device on it to be too close to the finished film roll.

[0024] Specifically, the sidewall of the insert 208 is symmetrically provided with holes 301 penetrating both sides, and the part of the top rod 201 inside the insert 208 is provided with a through hole corresponding to and communicating with the hole 301. The side of the slot 209 is provided with a bolt B302, and the end of the bolt B302 passes through the hole 301 and is threaded with a nut A.

[0025] In the above implementation method, in order to increase the stability of the connection between the push rod 201 and the insert block 208, the user can push the lower end of the push rod 201 into the slot 209 to the maximum extent. At this time, the push rod 201 can no longer be pushed. Then, the through hole at the lower end of the push rod 201 is connected to the hole 301. At this time, the user can insert the bolt B302 through it and tighten the nut A at its end to fix the push rod 201.

[0026] Specifically, a connecting block 303 is fixedly connected to the lower surface of the bottommost insert 208, and the connecting block 303 is attached to the bracket 101. A bolt C304 is threadedly connected to the side of the connecting block 303, and the end of the bolt C304 is pressed against the side of the bracket 101.

[0027] In the above embodiment, the user can tighten the bolt C304 so that its end is pressed against the bracket 101, thereby fixing the connecting block 303 to the bracket 101.

[0028] 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.

[0029] 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.

[0030] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0031] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0032] 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.

[0033] 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.

[0034] 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.
