Description

Technical Field

[0001] The invention relates to the technical field of food film winding equipment, and in particular to a winding equipment for producing food-grade films and a use method thereof. Background Art

[0002] Winding equipment for food-grade film production is a very important component in the food packaging industry. It is responsible for neatly winding the film materials manufactured on the production line onto paper or plastic cores for subsequent processing, transportation and storage. These devices must meet strict hygiene standards to ensure safety in contact with food.

[0003] The existing winding equipment for food-grade film production can refer to the Chinese utility model patent with patent announcement number CN217732135U, which discloses a winding equipment for food packaging film production, including a bottom plate, two support rods are arranged on one side of the upper end of the bottom plate, and the two support rods are arranged on the upper end of the side close to each other through the rotation of the shaft. A housing is fixedly arranged at the support rod at the upper end of the bottom plate and close to the rear end, and a motor is fixedly arranged inside the housing. An electric slide rail is fixedly arranged on the upper surface of the bottom plate and below the support rod at the front end, and a slider is fixedly arranged in the middle of the lower end of the support rod at the front end, and a first electric telescopic rod is fixedly arranged in the middle of the upper end of the bottom plate, and the upper end of the first electric telescopic rod is fixedly connected to a mounting frame, and a disinfection lamp is fixedly arranged inside the mounting frame. In the utility model, packaging films of different lengths can be rolled up, and when rolling up, the packaging film can be tensioned and disinfected, thereby improving its practicality.

[0004] The above device has a good use effect in actual production, but there are still some defects in actual use: First, the support rod on one side of the device slides on the electric slide rail through a slider to adjust the distance between the two mounting blocks, install winding rollers of different lengths, and wind up packaging films of different lengths; however, during the adjustment process, only the spacing between the two mounting blocks is adjusted, and the length of the winding roller itself is not adjusted. If the length of the winding roller itself is fixed, then for packaging films beyond this length range, the equipment cannot be effectively wound, which limits the adaptability of the equipment to products of different sizes and specifications; in addition, the device drives the mounting frame to rise and fall through the first electric telescopic rod, and disinfects the packaging film between the tensioning roller and the winding roller through the disinfection lamp to improve the hygiene and safety of the packaging film, but because the disinfection lamp can only disinfect the lower surface of the food film, the packaging film usually contacts food or other items on both sides in actual application, so only disinfecting the lower surface may not meet comprehensive hygiene requirements, especially for sensitive products that require double-sided protection. If the upper surface is not properly sterilized, contaminants may be introduced during subsequent processing or use, leading to an increased risk of cross-contamination. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the second motor of the present invention is started, the worm gear is driven to rotate through the worm, thereby rotating the horizontal threaded rod. Due to the threaded connection between the horizontal threaded rod and the horizontal threaded sleeve, the front support rod will move horizontally along the guide groove, thereby adjusting the distance between the first winding roller and the second winding roller.

[0017] 2.

The guide rod ensures that the screw sleeve moves in a straight line, increasing the stability and accuracy of the system. The sliding of the telescopic rod in the fixed sleeve and the buffering effect of the No. 2 spring enable the No. 1 mounting frame to automatically adjust its height within a certain range to adapt to food films of different thicknesses and maintain appropriate tension. The No. 1 ultraviolet disinfection lamp and the No. 2 ultraviolet disinfection lamp disinfect the upper and lower surfaces of the food film respectively to ensure comprehensive hygiene and safety. The equidistant setting and rotation connection of the lamps ensure uniform light coverage and improve the disinfection effect.

[0018] 3. The present invention adjusts the electric push rod through the controller to make the U-shaped block and the tension roller in the best position to ensure that the surface of the food film is flat and wrinkle-free. According to the thickness of the food film, the electric push rod is adjusted through the controller. The electric push rod adjusts the height of the U-shaped block through telescopic action, thereby changing the position of the tension roller to ensure that the food film maintains appropriate tension when passing through the dust removal area. After the air pump is started, air is extracted from the dust box through the shunt pipe and the connecting pipe to generate negative pressure. The negative pressure is transmitted to the dust suction pipe through the telescopic pipe and finally reaches the dust suction head to suck the dust and impurities on the surface of the food film into the dust suction pipe. The sucked dust and impurities are collected in the dust box and stored after filtering or separation. The cleaning door is opened regularly and the handle is used to conveniently clean the waste in the dust box to ensure the continuous and efficient operation of the system.

DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 8A winding device for producing food-grade films includes a support mechanism 100 and a winding mechanism 200, a disinfection mechanism 300 and a dust removal mechanism 400 arranged on the top thereof. The support mechanism 100 includes a bottom plate 101, and the top four corners of the bottom plate 101 are fixedly connected to support columns 102, and the tops of the four support columns 102 are fixedly connected to top plates 103:

[0029] Furthermore, a winding mechanism 200 for winding the food film is rotatably connected to the right side of the top of the bottom plate 101, and a disinfection mechanism 300 for disinfecting the upper and lower surfaces of the food film is provided at the center of the top of the bottom plate 101. The disinfection mechanism 300 is rotatably connected to the winding mechanism 200, and a dust removal mechanism 400 is fixedly connected to the top of the top plate 103.

[0030] The bottom plate 101 serves as the basic platform of the entire device, provides stable support, and carries all other components. Four support columns 102 evenly distributed around the bottom plate 101 increase the stability of the structure and support the top plate 103. The top plate 103 is fixed on the top of the four support columns 102, providing space and support for installing upper components (such as the dust removal mechanism 400).

[0031] The winding mechanism 200 is located on the top right side of the bottom plate 101, and is responsible for winding the food film output from the production line onto the reel. The disinfection mechanism 300 is arranged at the top center of the bottom plate 101, between the winding mechanism 200 and the dust removal mechanism 400, and disinfects the upper and lower surfaces of the food film. The dust removal mechanism 400 is fixed on the top of the top plate 103, and its function is to remove dust and other tiny particles on the surface of the food film before it enters the winding process.

[0032] Furthermore, the winding mechanism 200 includes front and rear support rods 201 correspondingly arranged on the front and rear sides of the top of the base plate 101. The two support rods 201 are both located on the right side of the top of the base plate 101. The bottom of the rear end support rod 201 is fixedly connected to the rear side of the top of the base plate 101, and the bottom of the front end support rod 201 is slidably connected to the front side of the top of the base plate 101.

[0033] The sliding connection of the front support rod 201 allows for easy adjustment of the spacing between the two support rods 201 to accommodate packaging films of different lengths and improve production efficiency. The fixed connection of the rear support rod 201 ensures the stability of the entire system and maintains good mechanical properties even when the front support rod 201 moves.

[0034] Furthermore, a slider No. 210 is fixedly connected to the bottom of the front end support rod 201, and a guide groove 104 is provided on the right side of the top of the bottom plate 101, which moves from the front end to the rear end of the bottom plate 101, and the slider No. 110 is slidably connected to the guide groove 104. The rear side of the top of the front end support rod 201 is rotatably connected to the No. 1 winding roller 202, and the front side of the top of the rear end support rod 201 is rotatably connected to the No. 2 winding roller 203. The No. 1 winding roller 202 and the No. 2 winding roller 203 are slidably connected between the sides close to each other, and a mounting plate 204 is fixedly connected to the top of the rear end support rod 201. A first motor 205 is fixedly connected to the top of the mounting plate 204, and an output shaft of the first motor 205 passes through the rear end support rod 201 and is rotatably connected between the side of the No. 2 winding roller 203 away from the No. 1 winding roller 202. A first protective cover 206 is provided on the outside of the first motor 205, and the bottom of the first protective cover 206 is fixedly connected to the top of the mounting plate 204.

[0035] By moving the front support rod 201 (by means of the sliding of the slider 210 in the guide groove 104), the distance between the winding roller 202 and the winding roller 203 can be adjusted to meet the requirements of different lengths of winding. The first motor 205 is started to drive the winding roller 203 to rotate. After the packaging film is output from the production line, it is guided between the winding roller 202 and the winding roller 203, and gradually wound onto the reel as the winding roller 203 rotates. Due to the sliding connection between the two winding rollers, the tension can be automatically adjusted as needed to ensure that the film is wound flat and wrinkle-free. The first protective cover 206 not only protects the safe operation of the first motor 205, but also facilitates daily inspection and maintenance work.

[0036] Furthermore, a plurality of connecting rods 207 are fixedly connected in a circular array on the side of the No. 1 winding roller 202 close to the No. 2 winding roller 203, and a plurality of circular grooves 208 are opened in a circular array on the side of the No. 2 winding roller 203 close to the No. 1 winding roller 202. The plurality of connecting rods 207 are matched with the plurality of circular grooves 208 one by one, and the plurality of connecting rods 207 extend into the interior of the circular grooves 208 away from one end of the No. 1 winding roller 202 and are slidably connected to the inner wall thereof, and a No. 1 spring 209 is provided inside the plurality of circular grooves 208, and one end of the plurality of No. 1 springs 209 is fixedly connected to one end of the plurality of connecting rods 207 away from the No. 1 winding roller 202, and the other end of the plurality of No. 1 springs 209 is fixedly connected to one side of the inner wall of the plurality of circular grooves 208.

[0037] During the winding process, as the packaging film is gradually wound onto the No. 2 winding roller 203, the connecting rod 207 will maintain a certain extension length under the action of the No. 1 spring 209, thereby maintaining an appropriate spacing between the two winding rollers. When the film thickness changes or the winding speed fluctuates, the connecting rod 207 can slide in the circular groove 208, and with the elastic recovery force of the No. 1 spring 209, automatically adjust the tension to ensure that the film is wound smoothly. Due to the existence of the connecting rod 207 and the No. 1 spring 209, the system can respond to changes in the film width, and even when switching between films of different widths, a good winding effect can be guaranteed. The No. 1 spring 209 provides a certain buffering effect to prevent the film from breaking or wrinkling due to sudden tension changes. The connecting rod 207 and the circular groove 208 arranged in a circular array ensure that the support points are evenly distributed throughout the rotation cycle, improving the stability and accuracy of the system.

[0038] Furthermore, a horizontal threaded sleeve 211 is fixedly connected to the bottom of the rear side of the front support rod 201, and a second slider 217 is fixedly connected to the bottom of the surface of the horizontal threaded sleeve 211. The second slider 217 extends to the inside of the guide groove 104 and is slidably connected thereto. A horizontal threaded rod 212 is threadedly connected to the inner wall of the horizontal threaded sleeve 211. The horizontal threaded rod 212 extends away from one end of the horizontal threaded sleeve 211 to the outside thereof and to the outside of the rear support rod 201. The horizontal threaded rod 212 is rotatably connected to the rear support rod 201. The horizontal threaded rod 212 is located on the front side of the rear support rod 201 and is fixed thereto. A worm wheel 213 is sleeved, a worm 214 is meshedly connected to the bottom of the worm wheel 213, a second motor 215 is fixedly connected to the rear end of the top right side of the base plate 101, an output shaft of the second motor 215 is fixedly connected to one end of the worm 214, a second protective cover 216 is provided outside the second motor 215, the bottom of the second protective cover 216 is fixedly connected to the top of the base plate 101, a first sprocket 218 is fixedly sleeved on the surface of one end of the horizontal threaded rod 212 away from the horizontal threaded sleeve 211, a chain 219 is meshedly connected to the surface of the first sprocket 218, and a second sprocket 303 is meshedly connected to the other side of the inner wall of the chain 219.

[0039] When the second motor 215 is started, the worm gear 213 is driven to rotate through the worm 214, thereby rotating the horizontal threaded rod 212. Due to the threaded connection between the horizontal threaded rod 212 and the horizontal threaded sleeve 211, the front support rod 201 will move horizontally along the guide groove 104, thereby adjusting the distance between the No. 1 winding roller 202 and the No. 2 winding roller 203.

[0040] Furthermore, the disinfection mechanism 300 includes a U-shaped frame 301 fixedly arranged at the top center of the base plate 101, the front and rear bottom of the U-shaped frame 301 are fixedly connected to the front and rear ends of the top of the base plate 101, a bidirectional screw rod 302 is rotatably connected to the lower part of the U-shaped frame 301, the front end of the bidirectional screw rod 302 is rotatably connected to one side of the inner wall of the U-shaped frame 301, the rear end of the bidirectional screw rod 302 extends to the rear side of the outside of the U-shaped frame 301 and is fixedly sleeved with a No. 2 sprocket 303, a No. 1 mounting frame 308 is provided at the lower part of the U-shaped frame 301, the surface of the No. 2 sprocket 303 is meshed with a chain 219, the front and rear sides of the surface of the bidirectional screw rod 302 are threadedly connected to screw rod sleeves 304, the tops of the two screw rod sleeves 304 are rotatably connected to inclined fixed sleeves 305, the four fixed sleeves 305 are slidably connected to the inside of the four fixed sleeves 305, and the tops of the four telescopic rods 306 extend to the outside of the fixed sleeves 305 The fixing sleeve 305 is rotatably connected to the front and rear sides of the bottom of the No. 1 mounting frame 308, a No. 2 spring 307 is provided inside the fixing sleeve 305, one end of the No. 2 spring 307 is fixedly connected to the bottom of the inner wall of the fixing sleeve 305, and the other end of the No. 2 spring 307 is fixedly connected to the bottom of the telescopic rod 306, and the top of the No. 1 mounting frame 308 is rotatably connected to multiple No. 1 ultraviolet disinfection lamps 309 arranged at equal distances, and the left and right sides of the bottom of the inner wall of the U-shaped frame 301 are fixedly connected to guide rods 310, and the two guide rods 310 are slidably connected to the two screw sleeves 304, and rectangular grooves 311 are correspondingly provided on the front and rear sides of the top of the U-shaped frame 301, a No. 2 mounting frame 312 is provided on the upper part of the U-shaped frame 301, and the bottom of the No. 2 mounting frame 312 is rotatably connected to multiple No. 2 ultraviolet disinfection lamps 313 arranged at equal distances, and the front surface of the U-shaped frame 301 is fixedly connected to a controller 314 for controlling the entire equipment.

[0041] When the position of the No. 1 mounting frame 308 needs to be adjusted, the second motor 215 drives the No. 2 sprocket 303 to rotate through the chain 219, thereby driving the bidirectional screw 302 to rotate. Due to the threaded connection between the bidirectional screw 302 and the screw sleeve 304, the two screw sleeves 304 will move in opposite directions, thereby changing the height position of the No. 1 mounting frame 308. The guide rod 310 ensures that the screw sleeve 304 moves in a straight line, increasing the stability and accuracy of the system. The sliding of the telescopic rod 306 in the fixed sleeve 305 and the buffering effect of the No. 2 spring 307 enable the No. 1 mounting frame 308 to automatically adjust its height within a certain range to adapt to food films of different thicknesses and maintain appropriate tension. The No. 1 ultraviolet disinfection lamp 309 and the No. 2 ultraviolet disinfection lamp 313 respectively disinfect the upper and lower surfaces of the food film to ensure comprehensive sanitation and safety. The equidistant setting and rotation connection of the lamps ensure uniform light coverage and improve the disinfection effect.

[0046] A method for using a winding device for producing food-grade films:

[0047] S1: Turn on the main power switch to ensure that the control system is powered on, start the controller 314, and perform initialization settings according to the screen prompts, lead the food film to be processed from the production line, pass it through the tension roller 405, and adjust it to a suitable position, guide the food film between the first winding roller 202 and the second winding roller 203, and prepare to start winding;

[0048] S2: According to the thickness of the food film, the electric push rod 402 is adjusted through the controller 314 to make the U-shaped block 401 and the tension roller 405 in the best position to ensure that the surface of the food film is flat and wrinkle-free. According to the thickness of the food film, the electric push rod 402 is adjusted through the controller 314. The electric push rod 402 adjusts the height of the U-shaped block 401 through telescopic action, thereby changing the position of the tension roller 405 to ensure that the food film maintains appropriate tension when passing through the dust removal area. After the air pump 412 is started, air is drawn out from the dust box 409 through the shunt pipe 413 and the connecting pipe 414 to generate negative pressure, which is transmitted to the dust suction pipe 406 through the telescopic pipe 408 and finally reaches the dust suction head 407, sucking dust and impurities on the surface of the food film into the dust suction pipe 406. The sucked dust and impurities are collected in the dust box 409, and stored after being filtered or separated. The cleaning door 410 is opened regularly, and the handle 411 is used to conveniently clean the waste in the dust box 409 to ensure the continuous and efficient operation of the system.

[0049] S3: When the position of the No. 1 mounting frame 308 needs to be adjusted, the second motor 215 drives the No. 2 sprocket 303 to rotate through the chain 219, thereby driving the bidirectional screw 302 to rotate. Due to the threaded connection between the bidirectional screw 302 and the screw sleeve 304, the two screw sleeves 304 will move in opposite directions, thereby changing the height position of the No. 1 mounting frame 308. The guide rod 310 ensures that the screw sleeve 304 moves in a straight line, increasing the stability and accuracy of the system. The sliding of the telescopic rod 306 in the fixed sleeve 305 and the buffering effect of the No. 2 spring 307 enable the No. 1 mounting frame 308 to automatically adjust its height within a certain range to adapt to food films of different thicknesses and maintain appropriate tension. The No. 1 ultraviolet disinfection lamp 309 and the No. 2 ultraviolet disinfection lamp 313 respectively disinfect the upper and lower surfaces of the food film to ensure comprehensive hygiene and safety. The equidistant setting and rotating connection of the lamps ensure uniform light coverage and improve the disinfection effect. The controller 314 can integrate sensors and PLC control systems to achieve real-time monitoring and automated management of ultraviolet lamps and mechanical components to ensure efficient operation of the equipment.

[0050] S4: When the second motor 215 is started, the worm gear 213 is driven to rotate through the worm 214, thereby rotating the horizontal threaded rod 212. Due to the threaded connection between the horizontal threaded rod 212 and the horizontal threaded sleeve 211, the front support rod 201 will move horizontally along the guide groove 104, thereby adjusting the distance between the No. 1 winding roller 202 and the No. 2 winding roller 203.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
