Description

Technical Field

[0001] The utility model relates to the technical field of stretch film processing, in particular to an auxiliary stretching tool for stretch film processing. Background Art

[0002] With the rapid development of the packaging industry, stretch film, as an important packaging material, is widely used in food, chemical, pharmaceutical, logistics and other fields with its excellent tensile properties, tear resistance, self-adhesiveness and other properties. In the production and processing of stretch film, the stretching link is a crucial step. Through the stretching operation, the molecules of the stretch film can be more closely intertwined, thereby enhancing the strength and stability of the film, helping to avoid problems such as rupture or breakage during packaging and transportation, and ensuring the safety of the packaged goods.

[0003] However, current stretching tools usually perform stretching operations by clamping the two ends of the stretch film with a clamp. When the traditional clamping mechanism clamps one end of the stretch film, wrinkles are easily generated. Usually, one end of the stretch film needs to be manually flattened in the clamp, which is troublesome to operate and reduces the processing efficiency of the stretch film. Therefore, the applicant proposes an auxiliary stretching tool for stretch film processing to solve the above problem. Utility Model Content

[0004] The utility model aims to provide an auxiliary stretching tool for processing a stretch film, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary stretching tool for processing a stretch film, comprising a base and a stretching mechanism mounted on the top of the base, and a clamping mechanism mounted in the stretching mechanism;

[0006] The stretching mechanism comprises two stretching frames which are slidably mounted on the top of the base and are symmetrically distributed, threaded rotating rods are rotatably mounted on the outer sides of the two stretching frames, and a support seat is fixedly mounted on the inner side of the stretching frame;

[0007] The clamping mechanism includes a movable plate slidably installed on the inner side of the stretching frame, a pressure plate corresponding to the support seat is fixedly installed at the bottom of the movable plate, two movable arms that penetrate the pressure plate and are symmetrically distributed are hingedly installed at the bottom of the movable plate, leveling rollers are rotatably installed at the bottom of the two movable arms, thrust springs are hingedly installed between the two movable arms and the movable plate, and a storage groove for the movable arms and the leveling rollers to move is opened on the pressure plate.

[0008] Preferably, a threaded sleeve penetrating the stretching frame and used in conjunction with the threaded rotating rod is fixedly mounted on one side of the movable plate, and the threaded rotating rod and the threaded sleeve are threadedly connected.

[0009] Preferably, a movable groove is provided on the stretching frame, and the threaded sleeve is slidably mounted between the movable groove.

[0010] Preferably, a hydraulic push rod is fixedly installed between the top of the base and the stretching frame, and a supporting foot is fixedly installed at the bottom of the base.

[0011] Preferably, the stretching frame and the base are slidably mounted via a moving block, and a moving groove for the moving block to slide is provided on the top of the base.

[0012] Preferably, an anti-skid pad is adhered to the bottom of the pressing plate, and an anti-skid sleeve is sleeved on the outer side of the leveling roller.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The auxiliary stretching tool for processing stretch film can put one end of the stretch film into the support seat and drive the clamping mechanism to move downward, so that the flattening roller can contact the stretch film. When the clamping mechanism continues to move downward, the movable arm can be forced to open outward, so that the flattening roller can roll outward on the surface of the stretch film, which can facilitate the flattening operation of the stretch film to avoid wrinkles. There is no need for manual flattening and wrinkle removal operations, which reduces the work intensity of the staff. When the flattening roller moves to the maximum position on both sides, the pressure plate can contact the stretch film, and the flattened stretch film can be clamped by the pressure plate, which can effectively integrate wrinkle removal and clamping, and can relatively quickly fix the stretch film, thereby improving the efficiency of the stretching process.

In the drawings or descriptions, similar or identical parts use the same reference numerals, and in actual applications, the shape, thickness or height of each component can be enlarged or reduced. The various embodiments listed in the utility model are only used to illustrate the utility model, and are not used to limit the scope of the utility model. Any obvious modifications or changes made to the utility model do not depart from the spirit and scope of the utility model.

[0023] See also Figure 1-5 As shown, the utility model proposes an auxiliary stretching tool for wrapping film processing, comprising a base 2 and a stretching mechanism 1 mounted on the top of the base 2, and a clamping mechanism 3 mounted in the stretching mechanism 1, the stretching mechanism 1 comprises two stretching frames 101 slidably mounted on the top of the base 2 and symmetrically distributed, the outer sides of the two stretching frames 101 are rotatably mounted with threaded rotating rods 103, the inner sides of the stretching frames 101 are fixedly mounted with support seats 4, the clamping mechanism 3 comprises a movable plate 301 slidably mounted on the inner sides of the stretching frames 101, a pressing plate 302 corresponding to the support seat 4 is fixedly mounted on the bottom of the movable plate 301, two movable arms 304 that are both penetrating the pressing plate 302 and are symmetrically distributed are hingedly mounted on the bottom of the movable plate 301, flattening rollers 305 are rotatably mounted on the bottoms of the two movable arms 304, thrust springs 303 are hingedly mounted between the two movable arms 304 and the movable plate 301, and a storage groove 308 for the movable arms 304 and the flattening roller 305 to move is provided on the pressing plate 302.

[0024] Based on the above-mentioned structural setting, the auxiliary stretching tooling for processing the stretch film is composed of a stretching mechanism 1, a base 2, and a clamping mechanism 3, wherein the clamping mechanism 3 can facilitate the integrated wrinkle removal and clamping operations on both ends of the stretch film, which can effectively save the operation time of fixing the stretch film and improve the processing efficiency. By moving the stretching mechanism 1 relatively away from each other, the stretching operation of the stretch film can be easily realized. Specifically, in the working process, by placing the end of the stretch film into the support seat 4, the threaded rotating rod 103 can be rotated to conveniently drive the entire clamping mechanism 3 to move up and down. When driving the clamping mechanism 3 to move downward, the flattening roller 305 can first contact the stretch film, and by continuing to move the clamping mechanism 3 downward, the movable arm 304 can be forced to flip outward. The flattening roller 305 can be pushed to roll to both sides on the surface of the wrapping film, and the thrust spring 303 can apply thrust to the movable arm 304, so that the flattening roller 305 can roll the wrapping film, and the rolling action of the flattening roller 305 can conveniently flatten the wrinkled position of the wrapping film, and when the flattening roller 305 moves to the maximum position, the flattening roller 305 and the movable arm 304 can extend into the storage groove 308, so that the pressure plate 302 can contact the wrapping film, and the flattened wrapping film can be conveniently pressed and held by the pressure plate 302, so that the wrinkle removal and clamping functions can be performed in one body, which effectively improves the work efficiency of fixing the wrapping film, and the relatively far movement of the stretching frame 101 can facilitate the stretching operation of the wrapping film.

[0025] Furthermore, a threaded sleeve 309 penetrating the stretching frame 101 and used in conjunction with the threaded rotating rod 103 is fixedly installed on one side of the movable plate 301, and the threaded rotating rod 103 and the threaded sleeve 309 are threadedly connected. The threaded rotating rod 103 can conveniently drive the threaded sleeve 309 to move up and down, so that the threaded sleeve 309 can synchronously drive the movable plate 301 to move up and down, and the entire clamping mechanism 3 can be driven to move up and down, which can facilitate the clamping operation of the wrapping film.

[0026] Furthermore, a movable groove 102 is provided on the stretching frame 101, and the threaded sleeve 309 is slidably installed between the movable groove 102. The threaded sleeve 309 can be stably slid vertically up and down by the limiting effect of the movable groove 102 on the threaded sleeve 309.

[0027] Furthermore, a hydraulic push rod 202 is fixedly installed between the top of the base 2 and the stretching frame 101, and a supporting foot 203 is fixedly installed at the bottom of the base 2. The hydraulic push rod 202 can push the stretching frame 101 to move closer to each other or away from each other through the telescopic function, so as to facilitate the stretching operation of the wrapping film.

[0028] Furthermore, the stretching frame 101 and the base 2 are slidably mounted via a moving block 104, and a moving groove 201 is provided on the top of the base 2 for the moving block 104 to slide. The moving groove 201 acts as a limiter on the moving block 104, so that the moving block 104 can slide along the moving groove 201, and the stretching frame 101 can perform a stable moving operation.

[0029] Furthermore, an anti-skid pad 307 is adhered to the bottom of the pressing plate 302, and an anti-skid sleeve 306 is sleeved on the outer side of the leveling roller 305. When the pressing plate 302 is used to press the wrapping film, the anti-skid pad 307 can be used to increase the friction between the pressing plate 302 and the wrapping film to avoid slipping during stretching. The anti-skid sleeve 306 can prevent the leveling roller 305 from slipping when rolling on the surface of the wrapping film, thereby improving the wrinkle removal effect of the leveling roller 305 on the wrapping film.
