Description

Technical Field

[0001] The utility model relates to the technical field of stretch film production, in particular to a film pressing device for stretch film production. Background Art

[0002] With the rapid development of the packaging industry, as an important packaging material, the market demand for stretch film is growing. Stretch film, also known as stretch film or heat shrink film, has been widely used in logistics, food, chemical industry and other fields due to its excellent tensile properties and self-adhesiveness. However, with the continuous improvement of market demand, higher requirements are also placed on the quality and performance of stretch film. In the production process of stretch film, it is usually necessary to roll up the stretch film. During the rolling process, in order to prevent the stretch film from loosening, it is usually necessary to perform a film pressing operation to improve the rolling effect.

[0003] However, most of the current film pressing devices for winding up the wrapping film form a film pressing effect by setting up a single pressing roller and a winding roller to squeeze. During the winding process, although a certain film pressing effect can be formed on the wrapping film, it is easy for the wrapping film to shift. At the same time, the film pressing operation at a single position is easy to make other positions loose. It is not convenient to automatically adjust as the volume of the wrapping film wound by the winding roller increases, which reduces the film pressing effect. For this reason, the applicant proposes a film pressing device for wrapping film production to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a film pressing device for producing stretch films, so as to solve the problems raised in the above-mentioned background technology.

[0006] The support mechanism comprises a support frame fixedly mounted on the top of the base, and a winding roller is mounted between the support frames through a mounting groove;

[0007] The film pressing mechanism includes two sliding frames which are slidably installed on the inner side of the support frame and are symmetrically distributed at the top and bottom of the winding roller. A support seat is fixedly installed on one side of the two sliding frames, a thrust spring is fixedly installed between the top of the support seat and the support frame, a pressure wheel is rotatably installed on one side of the support seat, and a limiting disk is fixedly installed on the outer end of the pressure wheel.

[0008] Preferably, a docking wheel is rotatably mounted inside the mounting groove, and docking blocks used in conjunction with the docking wheel are fixedly mounted at both ends of the winding roller.

[0009] Preferably, a motor is fixedly mounted at the rear end of the support frame, and an output end of the motor extends to the mounting groove and is fixedly connected to the docking wheel.

[0010] Preferably, a baffle corresponding to the mounting groove is installed through one side of the support frame, and the support frame and the baffle are fixed by a fixing bolt.

[0011] Preferably, the guiding mechanism includes a fixed frame fixedly mounted on the top of the base, a moving block is slidably mounted inside the fixed frame through a moving groove, a pressure roller is rotatably mounted between a threaded rotating rod extending from the fixed frame, and a supporting roller is rotatably mounted between the fixed frames and at the bottom of the pressure roller.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The film pressing device for the production of stretch film can use a plurality of pressure wheels 404 to roll and press the upper and lower sides of the winding roller during the process of winding the stretch film by the winding roller, which can effectively ensure that the stretch film will not become loose when it is wound up. The limit plate can fit the edge position of the winding roller, and the two sides of the stretch film can be limited, so that the stretch film is not easily offset when it is wound up, which effectively improves the winding quality of the stretch film. At the same time, as the volume of the stretch film on the winding roller gradually increases, the sliding frame can be used to move accordingly along the supporting frame, so that the film pressing mechanism can be automatically moved and adjusted along with the increase in the volume of the stretch film, and at the same time, it will not affect the film pressing effect on the stretch film, which effectively improves the use effect.

[0022] See also Figure 1-5 As shown, the utility model proposes a film pressing device for the production of stretch film, comprising a base 2 and a supporting mechanism 1 mounted on the top of the base 2, a film pressing mechanism 4 mounted on the inner side of the supporting mechanism 1, and a guide mechanism 3 mounted on the top of the base 2 and located on one side of the supporting mechanism 1, the supporting mechanism 1 comprises a supporting frame 101 fixedly mounted on the top of the base 2, a winding roller 5 is mounted between the supporting frames 101 through a mounting groove 105, the film pressing mechanism 4 comprises two sliding frames 401 slidably mounted on the inner side of the supporting frame 101 and symmetrically distributed on the top and bottom of the winding roller 5, a supporting seat 402 is fixedly mounted on one side of the two sliding frames 401, a thrust spring 405 is fixedly mounted between the top of the supporting seat 402 and the supporting frame 101, a pressing wheel 404 is rotatably mounted on one side of the supporting seat 402, and a limiting disk 403 is fixedly mounted on the outer end of the pressing wheel 404.

[0023] The film pressing device for producing the wrapping film is composed of a supporting mechanism 1, a base 2, a guiding mechanism 3, a film pressing mechanism 4 and a winding roller 5, wherein the supporting mechanism 1 can conveniently support the winding roller 5 so that the winding roller 5 can rotate to realize the winding operation of the wrapping film, the guiding mechanism 3 can conveniently guide the wrapping film and at the same time roll and press the wrapping film, so as to flatten the wrinkles of the wrapping film and avoid wrinkles when rolling up, and the film pressing mechanism 4 can conveniently roll and press the upper and lower sides of the wrapping film on the wrapping roller 5 at the same time, so that the wrapping film is not easy to become loose when rolling up, and at the same time can avoid the deviation of the wrapping film. Specifically, in the working process, the installation operation can be conveniently carried out by inserting the wrapping roller 5 into the installation groove 105, and the wrapping film can be passed through the guiding mechanism 3, so that the guide mechanism 3 can be used to conveniently guide and support the wrapping film, so that the wrapping film can be smoothly rolled up by the winding roller 5. The support frame 402 is provided with a plurality of pressure wheels 404, which can press and hold the edge of the winding film on the winding roller 5 from the top and the bottom at the same time, so that the winding film is not easy to be loose when it is wound, and the film pressing effect is effectively improved. At the same time, the limiting plate 403 can be fitted on the outer position of the winding film, so as to achieve the limiting effect of the winding film, so that the winding film is not easy to deviate when it is wound, and the winding quality effect is improved. At the same time, when the volume of the winding film increases during winding, the moving effect of the sliding frame 401 can be used to make the pressure wheel 404 move accordingly with the increase of the volume of the winding film, so that the pressure wheel 404 can always be in close contact with the winding film, without affecting the film pressing effect.

[0024] Furthermore, a docking wheel 106 is rotatably mounted inside the mounting groove 105, and docking blocks 501 used in conjunction with the docking wheel 106 are fixedly mounted at both ends of the winding roller 5. By inserting the docking block 501 into the docking wheel 106 for engagement, the rotation of the docking wheel 106 can be conveniently used to drive the winding roller 5 to rotate, so that the winding roller 5 can perform a winding operation on the wrapping film.

[0025] Further, a motor 102 is fixedly installed at the rear end of the support frame 101, and the output end of the motor 102 extends to the mounting slot 105 and is fixedly connected to the docking wheel 106. The motor 102 can provide power for the docking wheel 106, so as to drive the docking wheel 106 to rotate.

[0026] Furthermore, a baffle 103 corresponding to the mounting groove 105 is installed through one side of the support frame 101, and the support frame 101 and the baffle 103 are fixed by a fixing bolt 104. The mounting groove 105 can be conveniently blocked by sliding the baffle 103 to prevent the winding roller 5 from falling off from the mounting groove 105, and the baffle 103 can be fixed by the fixing bolt 104 to prevent the baffle 103 from moving.

The threaded rotating rod 305 and the fixed frame 301 are threadedly connected, and the threaded rotating rod 305 can be rotated to drive the moving block 304 to slide along the moving groove 306.

[0028] Furthermore, a pressure roller 303 is rotatably installed between the moving blocks 304, and a support roller 302 is rotatably installed between the fixed frames 301 and at the bottom of the pressure roller 303. The spacing between the pressure roller 303 and the support roller 302 can be adjusted by moving the moving blocks 304, and can be conveniently adjusted according to the thickness of the wrapping film. By passing the wrapping film between the pressure roller 303 and the support roller 302, the support roller 302 can be used to roll and support the wrapping film, and the pressure roller 303 can be used to press and hold the wrapping film, so that wrinkles can be removed before rolling up, which can avoid affecting the subsequent rolling and film pressing effect.
