Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, in particular to an anti-fog film winding device for food. Background Art

[0002] Anti-fog film is produced by the manufacturer using electron beam evaporation technology to coat high melting point nickel-cadmium alloy under low temperature vacuum state or using magnetron sputtering technology to sputter ceramic fine particles onto PET substrate at high speed. The anti-fog coating PET contains super hydrophilic nanomaterials, which dissociate the adsorbed water on the glass to form fine water droplets. Since the anti-fog coating PET has good hydrophilicity, when water contacts the film surface, it will completely wet and spread, that is, when it reaches the water absorption limit (saturation state), a thin transparent water film layer is formed, reducing the angle of contact between the film and water (the angle is below 7 degrees, and the production technology is world-leading), so that the surface tension of the film is completely close to the surface tension of water, and water cannot adhere to the surface of the film, achieving the purpose of anti-fog. Anti-fog film is usually used in some food packaging processes. In the production process of anti-fog film, a winding device is required to reel the anti-fog film.

[0003] For example, Chinese patent application No. 202320230680.0 discloses an anti-skew winding device for flat film production. When the tension of the flat film is small, the force of the flat film on the fourth roller becomes smaller, and the data of the pressure sensor becomes larger. The length of the second telescopic rod is adjusted to make the first slider slide downward. Since the heights of the second roller and the third roller remain unchanged, the pulling force on the flat film becomes larger, so that the data of the pressure sensor is maintained within a predetermined range, and the flat film maintains a fixed tension. When the offset is large, the first telescopic rod is adjusted to make the first roller tilt in the opposite direction, and the rotating block rotates around the mounting block to correct the offset of the flat film.

[0004] It has the following defects:

[0005] There is a lack of a shearing device for the flat film. Therefore, when the winding roller winds a flat film of a certain thickness, the flat film needs to be sheared manually. However, the manual shearing of the flat film will result in an inclined surface at the shearing point, which affects the winding quality of the flat film.

[0006] Therefore, those skilled in the art provide an anti-fog film winding device for food to solve the problems raised in the above background technology. Utility Model Content

A hydraulic expander 3021 is fixedly connected to the upper end surface of the first C-shaped frame 301. A cutter 304 is provided on the upper inner side of the first C-shaped frame 301. The positions of the cutter 304 and the groove 303 correspond to each other. A connecting plate 305 is installed on the upper end surface of the cutter 304. The output end of the hydraulic expander 3021 passes through the first C-shaped frame 301 and is connected to the connecting plate 305.

[0026] When in use: first, one end of the anti-fog film for food is passed through the guide conveying device 2 and the anti-fog film cutting device 3 in sequence and wound on the anti-fog film winding mechanism 4, and then the anti-fog film for food is wound by the anti-fog film winding mechanism 4. When the anti-fog film winding mechanism 4 winds the anti-fog film to a certain thickness, the hydraulic retractor 3021 is started. The start of the hydraulic retractor 3021 drives the connecting plate 305 to move toward the anti-fog film for food. The movement of the connecting plate 305 drives the cutter 304 to move. When the cutter 304 sets the anti-fog film for food on the upper end surface of the support plate 302, the cutter 304 is continued to be pushed by the hydraulic retractor 3021 until the cutter 304 cuts off the anti-fog film for food.

[0027] Beneficial effect: The anti-fog film cutting device 3 replaces the manual cutting of the anti-fog film, which can avoid the problem of manually cutting an inclined surface at the cutting position of the anti-fog film, thereby affecting the winding quality of the anti-fog film.

[0028] like Figure 4 and Figure 5 As shown, the guide conveying device 2 includes a second U-shaped frame 201, and a group of extrusion wheels 202 are rotatably connected on both sides of the inner side of the second U-shaped frame 201, each group of extrusion wheels 202 has two extrusion wheels 202, and the two extrusion wheels 202 are arranged up and down, and guide wheels 203 are rotatably connected on both sides of the inner side of the second U-shaped frame 201, and the two guide wheels 203 are located between the two groups of extrusion wheels 202.

A driver 206 is fixedly installed on one side wall of the second U-shaped frame 201, and the output end of the driver 206 is connected to a fixed plate 204.

[0029] During use: when the anti-fog film for food passes through the guide conveying device 2, the anti-fog film for food will pass through two groups of extrusion wheels 202, the upper end surfaces of the two guide wheels 203, and between the two rollers 205 in sequence. If it is necessary to adjust the tension of the anti-fog film for food, start the driver 206. The start of the driver 206 drives the fixed plate 204 connected thereto to rotate. The rotation of the fixed plate 204 drives the two rollers 205 to rotate. The rotation of the two rollers 205 will adjust the tension of the anti-fog film for food passing between the two rollers 205.

[0030] Beneficial effect: The setting of the guiding and conveying device 2 not only plays a role in guiding and conveying the anti-fog film for food, but also can adjust the tension of the anti-fog film for food, so as to avoid the anti-fog film for food from being broken due to excessive tension during transportation, or from being wrinkled due to excessive tension.

[0031] like Figure 6 As shown, the anti-fog film winding mechanism 4 includes two limit plates 401, which are fixedly mounted on the front and rear sides of one side of the upper end surface of the support base 1, and an anti-fog film winding wheel 402 is arranged between the two support bases 1.

[0033] Beneficial effects: the anti-fog film winding mechanism 4 not only plays the role of winding the anti-fog film for food, but also has a simple structure and is easy to operate.

[0034] The working principle of the utility model is:

[0035] First, when one end of the anti-fog film for food is passed through the guide conveyor 2 in sequence, the anti-fog film for food will pass through the two sets of extrusion wheels 202 in sequence, be placed on the upper end surfaces of the two guide wheels 203, between the two rollers 205, and the upper end surface of the support plate 302, and be rolled up on the anti-fog film winding wheel 402, and then the drive motor 404 is started, and the drive of the drive motor 404 drives the anti-fog film winding wheel 402 to rotate, and the rotation of the anti-fog film winding wheel 402 will wind up the anti-fog film for food. When the anti-fog film winding wheel 402 winds the anti-fog film for food to a certain thickness, the hydraulic retractor 3021 is started. The start of the hydraulic retractor 3021 drives the connecting plate 305 to move toward the anti-fog film for food. The movement of the connecting plate 305 drives the cutter 304 to move. When the cutter 304 sets the anti-fog film for food on the upper end surface of the support plate 302, the cutter 304 is pushed continuously by the hydraulic retractor 3021 until the cutter 304 cuts the anti-fog film for food. If the tension of the anti-fog film for food needs to be adjusted, the driver 206 is started. The start of the driver 206 drives the fixed plate 204 connected thereto to rotate. The rotation of the fixed plate 204 drives the two rollers 205 to rotate. The rotation of the two rollers 205 will adjust the tension of the anti-fog film for food passing between the two rollers 205.
