Description

Technical Field

[0001] This utility model relates to the field of food packaging bag production technology, and more specifically, to an anti-sticking and flattening device for packaging film winding. Background Technology

[0002] The anti-sticking and flattening device for food packaging bags is a piece of equipment used to solve the problems of sticking and unevenness that occur in the production, printing, and sealing processes of packaging bags. However, existing anti-sticking and flattening devices cannot achieve a consistently tight effect on food plastic bags of different thicknesses during normal use. Therefore, its flattening effect is effective when dealing with food of different thicknesses and elasticities. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an anti-sticking and flattening device for packaging film winding, which has the advantage of being able to maintain tension at any time.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-sticking and flattening device for packaging film winding, comprising a support leg, a motor fixedly installed above the support leg, a lead screw fixedly installed at the output end of the motor, a connecting plate meshing with the outer side of the lead screw, a positioning sleeve fixedly installed on the outer side of the connecting plate, a connecting shaft sleeved inside the positioning sleeve, a flattening roller fixedly installed on the outer side of the connecting shaft, a silicone sleeve fixedly installed on the outer side of the flattening roller, and a limit plate fixedly installed at the bottom end of the lead screw.

[0005] As a preferred embodiment of this utility model, the support leg has a groove inside, a slider is slidably connected inside the groove, a docking plate is fixedly installed on the outside of the slider, a telescopic rod is fixedly installed above the docking plate, a spring is sleeved on the outside of the telescopic rod, an mounting block is fixedly installed above the spring, a fixed shaft is rotatably connected inside the mounting block, and a compression wheel is fixedly installed on the outside of the fixed shaft.

[0006] As a preferred embodiment of this utility model, a fixing plate is fixedly installed above the docking plate, and a screw hole is opened inside the supporting leg. A bolt is engaged inside the screw hole, and the bolt passes through the inside of the fixing plate.

[0007] As a preferred embodiment of this utility model, there are two support legs and two motors, with the two support legs and two motors located on the left and right sides of the silicone sleeve, respectively. There are also two lead screws and two connecting plates, with the two lead screws located at the bottom of the two motors, respectively.

[0008] In a preferred embodiment of this invention, the diameter of the flattening roller is greater than the diameter of the connecting shaft, the diameter of the silicone sleeve is greater than the diameter of the flattening roller, and the connecting shaft, the flattening roller, and the silicone sleeve are all located between the two supporting legs.

[0009] As a preferred embodiment of this utility model, there are multiple screw holes, which are located inside the two support legs respectively. There are four bolts, which respectively engage with four of the multiple screw holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model features a motor fixedly mounted above the support leg, a lead screw fixedly mounted at the motor's output end, a connecting plate engaged with the lead screw, a positioning sleeve fixedly mounted with the connecting plate, a connecting shaft sleeved inside the positioning sleeve, a flattening roller fixedly mounted with the connecting shaft, and a silicone sleeve fixedly mounted with the flattening roller. When dealing with food packaging bags of varying tightness, the motor is started to rotate the lead screw, causing it to engage with the connecting plate. Since the connecting plate and positioning sleeve are fixedly connected, and the positioning sleeve houses the connecting shaft, the overall height of the connecting shaft can be adjusted after the lead screw engages with the connecting plate. This allows the height of the flattening roller and silicone sleeve to be adjusted, ensuring that the silicone sleeve always maintains a tight fit with the food packaging bag.

[0012] 2. This utility model features a telescopic rod fixedly installed above the docking plate, a spring sleeved on the outside of the telescopic rod, an mounting block fixedly installed above the spring, a fixed shaft rotatably connected inside the mounting block, and a squeezing wheel fixedly installed on the outside of the fixed shaft. When the food packaging bag is flattened during production, the silicone sleeve will adhere to the food packaging bag. At this time, since the squeezing wheel is located at the bottom and edge of the silicone sleeve, the spring provides elasticity to push the mounting block upward, causing the fixed shaft to be pushed upward, so that the squeezing wheel adheres to the bottom of the silicone sleeve. This results in the two sides of the food packaging bag being clamped by the squeezing wheel and the fixed plate, thus preventing the two sides of the food packaging bag from curling up.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown, this utility model provides an anti-sticking and flattening device for packaging film winding, including a support leg 1, a motor 2 fixedly installed above the support leg 1, a lead screw 3 fixedly installed at the output end of the motor 2, a connecting plate 4 meshing with the outside of the lead screw 3, a positioning sleeve 5 fixedly installed on the outside of the connecting plate 4, a connecting shaft 6 sleeved inside the positioning sleeve 5, a flattening roller 7 fixedly installed on the outside of the connecting shaft 6, a silicone sleeve 8 fixedly installed on the outside of the flattening roller 7, and a limit plate 9 fixedly installed at the bottom end of the lead screw 3.

[0021] When dealing with food packaging bags of varying tightness, the motor 2 is started to drive the lead screw 3 to rotate, causing the lead screw 3 to engage with the connecting plate 4. Since the connecting plate 4 and the positioning sleeve 5 are fixedly connected, and the positioning sleeve 5 sleeves the connecting shaft 6 inside, the overall height of the connecting shaft 6 can be adjusted after the lead screw 3 engages with the connecting plate 4. This allows the connecting shaft 6 to adjust the height of the flattening roller 7 and the silicone sleeve 8, ensuring that the silicone sleeve 8 always maintains a tight fit with the food packaging bag.

[0022] The support leg 1 has a groove 10 inside, a slider 11 is slidably connected inside the groove 10, a docking plate 12 is fixedly installed on the outside of the slider 11, a telescopic rod 13 is fixedly installed above the docking plate 12, a spring 14 is sleeved on the outside of the telescopic rod 13, an installation block 15 is fixedly installed above the spring 14, a fixed shaft 16 is rotatably connected inside the installation block 15, and a pressing wheel 17 is fixedly installed on the outside of the fixed shaft 16.

[0023] When food packaging bags are being produced and laid out, the silicone sleeve 8 will be attached to the food packaging bag. At this time, since the extrusion roller 17 is located at the bottom and edge of the silicone sleeve 8, and the spring 14 provides elasticity to push the mounting block 15 upward, the fixing shaft 16 will be pushed upward to make the extrusion roller 17 attach to the bottom of the silicone sleeve 8, thereby clamping the two sides of the food packaging bag and achieving the effect of keeping the two sides of the food packaging bag from curling up.

[0024] Among them, a fixing plate 18 is fixedly installed on the top of the docking plate 12, and a screw hole 19 is opened inside the support leg 1. A bolt 20 is engaged inside the screw hole 19 and passes through the inside of the fixing plate 18.

[0025] The main function of the fixing plate 18 is to fix the docking plate 12 in a suitable position after the sliding action of the slider 11 and the slide groove 10 is used, and then fix it by the engagement of the bolt 20 and the screw hole 19, so as to make the docking plate 12 easy to fix.

[0026] There are two support legs 1 and two motors 2, which are located on the left and right sides of the silicone sleeve 8, respectively. There are two lead screws 3 and two connecting plates 4, which are located at the bottom of the two motors 2.

[0027] After the two motors 2 are started, they will drive the two lead screws 3 to rotate, so that the two connecting plates 4 mesh with the two lead screws 3, thereby enabling the silicone sleeve 8 to maintain balance when it is raised and lowered.

[0028] The diameter of the flattening roller 7 is greater than that of the connecting shaft 6, and the diameter of the silicone sleeve 8 is greater than that of the flattening roller 7. The connecting shaft 6, the flattening roller 7, and the silicone sleeve 8 are all located in the middle of the two support legs 1.

[0029] The main function of the flattening roller 7 is to facilitate the conveying of food plastic packaging through the rotation of the connecting shaft 6 and the positioning sleeve 5.

[0030] There are multiple screw holes 19, which are located inside the two support legs 1 respectively. There are four bolts 20, which engage with four of the screw holes 19 respectively.

[0031] Multiple screw holes 19 are distributed vertically. Their main function is to facilitate the fixing of the fixing plate 18 through the meshing action of the screw holes 19 and the bolts 20 when the height of the docking plate 12 needs to be adjusted. At the same time, the fixing plate 18 and the docking plate 12 are fixedly connected. Therefore, the fixing plate 18 will drive the docking plate 12 to be fixed, thereby achieving the effect of adjusting the height of the telescopic rod 13 and the spring 14 and fixing them.

[0032] Working principle and usage process of this utility model:

[0033] First, a motor 2 is fixedly installed above the support leg 1. A lead screw 3 is fixedly installed at the output end of the motor 2. A connecting plate 4 is engaged on the outside of the lead screw 3. A positioning sleeve 5 is fixedly installed on the outside of the connecting plate 4. A connecting shaft 6 is sleeved inside the positioning sleeve 5. A flattening roller 7 is fixedly installed on the outside of the connecting shaft 6. A silicone sleeve 8 is fixedly installed on the outside of the flattening roller 7. When dealing with food packaging bags of different tightness, the motor 2 is started to drive the lead screw 3 to rotate, so that the lead screw 3 engages with the connecting plate 4. Since the connecting plate 4 and the positioning sleeve 5 are fixedly connected, and the positioning sleeve 5 sleeves the connecting shaft 6 inside, after the lead screw 3 engages with the connecting plate 4, the overall height of the connecting shaft 6 can be adjusted. This keeps the height of the flattening roller 7 and the silicone sleeve 8 adjusted by the connecting shaft 6, so that the silicone sleeve 8 always keeps tightly fitted to the food packaging bag.

[0034] Secondly, a telescopic rod 13 is fixedly installed above the docking plate 12. A spring 14 is sleeved on the outside of the telescopic rod 13. An mounting block 15 is fixedly installed above the spring 14. A fixed shaft 16 is rotatably connected inside the mounting block 15. An extrusion wheel 17 is fixedly installed on the outside of the fixed shaft 16. When the food packaging bag is flattened during production, the silicone sleeve 8 will adhere to the food packaging bag. At this time, since the extrusion wheel 17 is located at the bottom and edge of the silicone sleeve 8, and the spring 14 provides elasticity to push the mounting block 15 upward, the fixed shaft 16 will be pushed upward to make the extrusion wheel 17 adhere to the bottom of the silicone sleeve 8. Thus, the two sides of the food packaging bag are clamped by the extrusion wheel 17 and the fixed plate 18, so as to keep the two sides of the food packaging bag from curling up.

[0035] Finally, when the height of the docking plate 12 needs to be adjusted, the height of the docking plate 12 is first adjusted by the sliding action of the slide groove 10 and the slider 11, and then fixed by the fixing plate 18 through the meshing action of the screw hole 19 and the bolt 20. At the same time, the fixing plate 18 and the docking plate 12 are fixedly connected, so the fixing plate 18 will drive the docking plate 12 to be fixed, thereby achieving the effect of adjusting the height of the docking plate 12, which in turn drives the telescopic rod 13 and the spring 14 to be fixed.
