A mobile stretch film support

Abstract

This application discloses a movable stretch film support, relating to the field of stretch film, including a film roll, a mounting base, a folding assembly, and a cutting assembly. A sliding interlocking frame unlocks the first and second rotating plates. The second rotating plate is then rotated to engage with the forearm, causing the interlocking frame to engage with the L-shaped fixing block, thus securing the second rotating plate to the forearm. The first rotating plate rotates to engage with the interlocking block, locking the first rotating plate to the rear arm. The entire support can be lifted by gripping two levers for easy removal and movement. A toggle plate retracts a compression spring into the rotating frame, unlocking the frame from the forearm. The rotating frame is then rotated to engage with the locking block, limiting its maximum rotation angle. After rotation, the auxiliary support rod can be opened, engaging with the interlocking slot on the outer surface of the forearm to support the rotating frame. This allows for folding and storage of the cutting component, facilitating transport.

Description

Technical Field

[0001] This utility model relates to the field of stretch film technology, and in particular to a mobile stretch film support. Background Technology

[0002] Stretch film, also known as stretch wrap or stretch packaging film, is a plastic film material widely used in the packaging industry. It is mainly made of polyethylene or other plastic materials through blow molding or casting processes. It has good tensile properties and transparency, and can tightly wrap items to provide protection and fixation. Stretch film plays an important role in logistics, warehousing, transportation and other industries.

[0003] When using existing stretch film to wrap items, a stretch film holder is required. Before use, the stretch film needs to be inserted into the outer surface of the rotating shaft, and then the rotating shaft is installed on the stretch film holder. Then, one end of the stretch film can be pulled out to wrap the stretch film around the surface of the item.

[0004] The existing stretch film support system mainly uses a fixed triangular bracket to achieve the support effect. However, during use, it is often necessary to move the stretch film support system to a designated location. However, the existing support system cannot be folded and stored, so the entire support system can only be moved, which is quite inconvenient. Utility Model Content

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 and Figure 3This is the first embodiment of the present utility model. This embodiment provides a movable winding film support, including a film roll 1, with mounting bases 2 installed at both ends of the film roll 1, and a folding component 3 provided below the mounting bases 2.

[0031] The folding assembly 3 includes a forearm 301 hinged to the lower surface of the mounting base 2, a rear arm 302 hinged to the lower surface of the mounting base 2, a second rotating plate 307 hinged to the bottom end of the forearm 301 near the rear arm 302, a first rotating plate 305 hinged to the bottom end of the rear arm 302 near the forearm 301, a plug-in frame 306 movably connected to the outer surface of the end of the second rotating plate 307 near the first rotating plate 305, and a grip bar 309 fixedly connected between the two forearms 301 and the two rear arms 302.

[0032] Specifically, a limiting groove is provided on the outer surface of the second rotating plate 307, and a rectangular slot is provided inside the insertion frame 306 to cooperate with the first rotating plate 305. The inner wall of the rectangular slot is provided with a limiting block that cooperates with the limiting groove. Through the cooperation of the limiting groove and the limiting block, the insertion frame 306 is prevented from separating from the second rotating plate 307. Through the insertion of the rectangular slot inside the insertion frame 306 with the first rotating plate 305, the first rotating plate 305 and the second rotating plate 307 cannot rotate after the insertion is completed.

[0033] Specifically, the inner wall of the rectangular slot inside the plug-in frame 306 has a limiting protrusion. An L-shaped fixing block 304, which mates with the plug-in frame 306, is fixedly connected to the outer surface of the forearm 301. Both the L-shaped fixing block 304 and the outer surface of the first rotating plate 305 have limiting grooves that mate with the limiting protrusions. A plug block 303 is fixedly connected to the side of the rear arm 302 closest to the first rotating plate 305. The interior of the first rotating plate 305 has a plug hole that mates with the plug block 303. Through the cooperation of the limiting protrusions and limiting grooves, the plug-in frame 306 and the second rotating plate 301 are locked together. 07. To prevent the second rotating plate 307 from separating from the first rotating plate 305, at least two limiting protrusions and limiting grooves are provided. The number of limiting protrusions and limiting grooves can be increased to four or more depending on the specifications of the wrapping film used. By increasing the number of limiting protrusions and limiting grooves, the friction between the insertion frame 306 and the first rotating plate 305 can be increased when the bracket carries a large weight of wrapping film, thereby ensuring that the insertion frame 306 and the first rotating plate 305 cannot separate, and ensuring that the front arm 301 and the rear arm 302 maintain a fixed opening angle.

[0034] Specifically, a fixing rod 308 is fixedly connected between the two forearms 301. The fixing rod 308 is positioned above the cutting assembly 4. The fixing rod 308 allows one end of the pulled-out film roll 1 to pass under the fixing rod 308, achieving tension and keeping the film roll 1 unfolded after being pulled out, which is convenient for winding.

[0035] Furthermore, the sliding insertion frame 306 separates from the first rotating plate 305, thereby unlocking the first rotating plate 305 from the second rotating plate 307. Then, the second rotating plate 307 is rotated to fit against the forearm 301. After fitting, the sliding insertion frame 306 extends out, thereby driving the insertion frame 306 to fit against the L-shaped fixing block 304. The limiting protrusion on the inner side of the insertion frame 306 cooperates with the limiting groove on the outer surface of the L-shaped fixing block 304 to fix the second rotating plate 307 against the forearm 301. The first rotating plate 305 then rotates to cooperate with the insertion block 303, thereby locking the first rotating plate 305 against the rear arm 302. The forearm 301 and the rear arm 302 can then be rotated and fitted together. By holding the two grips 309, the entire bracket can be lifted.

[0036] Example 2

[0037] Reference Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment, and the outer surface of the forearm 301 is provided with a cutting component 4;

[0038] The cutting assembly 4 includes a rotating frame 401 hinged to the outer surface of the forearm 301. A cutting blade is slidably disposed at the top of the rotating frame 401. An auxiliary support rod 404 is hinged to the side of the rotating frame 401 near the forearm 301. Compression springs 406 are fixedly connected inside both ends of the rotating frame 401. A limit pin 403 is fixedly connected to the end of the compression spring 406 near the forearm 301.

[0039] Specifically, a rectangular groove is provided on the outer surface of the forearm 301, and the rotating frame 401 is hinged inside the rectangular groove by a pin. The inner wall of the rectangular groove is provided with an insertion port that cooperates with the auxiliary support rod 404. A snap-fit ​​block 402 is fixedly connected to the outer surface of the forearm 301. The rectangular groove allows the rotating frame 401 to be rotated and stored inside the rectangular groove. The rotating frame 401 has a groove on the side near the forearm 301 that cooperates with the auxiliary support rod 404. The auxiliary support rod 404 is movably connected inside the groove by a pin.

[0040] Specifically, a toggle plate 405 is fixedly connected to the outer surface of the limit pin 403. A rectangular opening that cooperates with the toggle plate 405 is provided on the side of the rotating frame 401 near the forearm 301. The limit pin 403 can be easily retracted through the toggle plate 405. The rectangular opening facilitates the movement of the toggle plate 405.

[0041] Furthermore, by pushing the actuating plate 405, the compression spring 406 is driven to retract into the rotating frame 401, thereby unlocking the rotating frame 401 from the forearm 301. The rotating frame 401 is then rotated to abut against the locking block 402, thereby limiting the maximum rotation angle of the rotating frame 401. After rotation, the auxiliary support rod 404 can be rotated open, allowing the auxiliary support rod 404 to engage with the insertion port on the outer surface of the forearm 301, thereby supporting the rotating frame 401. The connection relationship, working principle, and operation sequence between the cutter component and other components are existing technologies and are common knowledge known to those skilled in the art, and will not be elaborated further here.

[0042] Working principle: When handling the stretch film support, the sliding insertion frame 306 separates from the first rotating plate 305, thereby unlocking the first rotating plate 305 from the second rotating plate 307. Then, the second rotating plate 307 rotates to fit against the forearm 301. After fitting, the sliding insertion frame 306 extends out, thereby driving the insertion frame 306 to fit against the L-shaped fixing block 304. The limiting protrusion on the inner side of the insertion frame 306 cooperates with the limiting groove on the outer surface of the L-shaped fixing block 304 to fix the second rotating plate 307 against the forearm 301. The first rotating plate 305 rotates to engage with the insert block 303, thereby locking the first rotating plate 305 and the rear arm 302 together. This allows the forearm 301 and the rear arm 302 to rotate and fit together. By holding the two levers 309, the entire bracket can be lifted, making it easy to pick up and move without requiring strenuous handling. After moving the bracket to the designated position, the same steps are repeated to rotate and open the forearm 301 and the rear arm 302, causing the first rotating plate 305 and the second rotating plate 307 to rotate to the docking position. Then, the sliding insert frame 3... 06. The first rotating plate 305 is locked by the insertion frame 306, ultimately locking the first rotating plate 305 and the second rotating plate 307, thereby limiting the rotation angle of the forearm 301 and the rear arm 302. Then, by pushing the actuating plate 405, the compression spring 406 is driven to retract into the rotating frame 401, thereby unlocking the rotating frame 401 and the forearm 301. The rotating frame 401 is rotated until it abuts against the locking block 402, thereby limiting the maximum rotation angle of the rotating frame 401. After the rotation is completed, the auxiliary support rod 404 can be rotated open, allowing the auxiliary support rod to rotate and open. The auxiliary support rod 404 engages with the insertion port on the outer surface of the forearm 301 to support the rotating frame 401. After the film roll 1 is installed between the two mounting seats 2, one end of the film roll 1 can be pulled out and passed under the fixing rod 308. The fixing rod 308 can then act as a limiting roller to assist the film roll 1 in winding. After winding, the film can be pressed down on the top of the rotating frame 401, and the cutting component at the top of the sliding rotating frame 401 can drive the film to cut, thus completing the transfer of the film support and the film winding operation.
