Description

Technical Field

[0001] The utility model belongs to the technical field of plastic packaging films, and specifically relates to a drying device for plastic packaging films. Background Art

[0002] The share of plastic packaging and plastic packaging products in the market is increasing. Especially for composite plastic flexible packaging, it has been widely used in the fields of food, medicine, chemical industry, etc. Among them, food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, cooked food packaging, fast food packaging, etc. These products have brought great convenience to people's lives.

[0003] After retrieval, a document with the publication number (CN213273619U) discloses a plastic packaging film drying device, including: a base, a storage rack, a winding shaft, a drying layer and a fixing plate. A storage rack is fixed on one side of the top of the base, and a winding shaft is fixed on one side of the top of the base located beside the storage rack. Two drying layers are symmetrically arranged on one side of the top of the base far away from the storage rack with respect to the winding shaft, and a fixing plate is fixed on one side of the top of the base far away from the drying layer with respect to the winding shaft.

[0004] Due to the linkage effect of the above device, the first driven pulley, the second driven pulley and the auxiliary pulley rotate simultaneously. Since the first driven pulley and the second driven pulley are respectively fixedly connected to the first conveying rod and the second conveying rod, the first conveying rod and the second conveying rod are driven to rotate. Such a plastic packaging film drying device realizes drying and conveying the plastic packaging film in two levels under the combined action of the lifting mechanism, the transmission mechanism and the sliding mechanism.

[0005] The above device only dries the plastic packaging film through the cooperation of the drying layer and the fan, but the plastic packaging film passes through the transmission mechanism, resulting in that the device can only dry one side of the plastic packaging film, resulting in poor drying effect. At the same time, drying one side for a long time will cause that side to break or have a fault due to over-drying, affecting the quality of the plastic packaging film.

[0006] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0012] As a preferred embodiment of the present invention, a limiting rod is provided in the middle of the gear, one end of the limiting rod is threadedly connected to the gear, and the other end of the limiting rod is rotatably connected to the side plate.

[0013] As a preferred embodiment of the present invention, a spring is sleeved on the limiting rod, one end of the spring is fixedly connected to the gear, and the other end of the spring is fixedly connected to the limiting rod.

[0014] As a preferred embodiment of the present invention, hydraulic presses are symmetrically arranged in the base, the hydraulic presses are fixedly connected to the inner wall of the base, and the side plates are fixedly connected to the output shafts of the hydraulic presses.

[0016] The present invention has the following beneficial effects compared with the prior art:

[0017] 1. This plastic packaging film drying equipment uses hot air blowers arranged diagonally to heat the surface of the plastic packaging film with hot air, raising the temperature of the surface of the plastic packaging film, thereby evaporating the moisture on the surface of the plastic packaging film.

Place the plastic packaging film between the two fixed rollers 11 at both ends, and let one of the fixed rollers 11 rotate with the help of the motor to pull the plastic packaging film towards the fixed roller 11 on the motor side. At this time, the hot air blower 12 arranged diagonally heats the surface of the plastic packaging film with hot air to raise the temperature of the surface of the plastic packaging film, so as to evaporate the moisture on the surface of the plastic packaging film. By heating intermittently on both sides, the situation of the plastic packaging film being broken or having a fault due to overheating of the same surface for too long is avoided.

[0031] Among them, the clamping assembly further includes a first transmission block 33 and a second transmission block 34. Both the first transmission block 33 and the second transmission block 34 are arranged on one side of the side plate 31. The first transmission block 33 and the second transmission block 34 are both rotatably connected to the side plate 31. There is a gap between the first transmission block 33 and the second transmission block 34. One end of each of the first transmission block 33 and the second transmission block 34 is fixedly connected to the clamping plate 3. The clamping assembly further includes a gear 5. Multiple groups of gears 5 are arranged on the other side of the side plate 31. The gear 5 is rotatably connected to the side plate 31. The gear 5 is fixedly connected to the first transmission block 33 and the second transmission block 34 respectively. Multiple groups of gears 5 are meshed with each other. The clamping assembly further includes a cylinder 32. The cylinder 32 is arranged on the side plate 31 on one side. The cylinder 32 is fixedly connected to the side plate 31. The other end of the first transmission block 33 is rotatably connected to the output shaft of the cylinder 32. A limiting rod 51 is arranged in the middle of the gear 5. One end of the limiting rod 51 is threadedly connected to the gear 5. The other end of the limiting rod 51 is rotatably connected to the side plate 31. A spring 52 is sleeved on the limiting rod 51. One end of the spring 52 is fixedly connected to the gear 5. The other end of the spring 52 is fixedly connected to the limiting rod 51. Hydraulic presses 4 are symmetrically arranged in the base 1. The hydraulic presses 4 are fixedly connected to the inner wall of the base 1. The side plate 31 is fixedly connected to the output shaft of the hydraulic press 4. Arc-shaped grooves are formed on the corresponding surfaces of the first transmission block 33 and the second transmission block 34. The radian of the arc-shaped groove is greater than the radian of the second transmission block 34. The first transmission block 33 is integrally in an irregular elliptical shape. The output shaft of the cylinder 32 pulls one end of the first transmission block 33 to rotate. The rotation of the first transmission block 33 drives the gear 5 to rotate. The two gears 5 are meshed with each other. The gear 5 drives the second transmission block 34. The first transmission block 33 and the second transmission block 34 rotate towards each other and drive the clamping plate 3. The plastic packaging film passes between the clamping plates 3. The clamping plates 3 scrape off the residual moisture on the surface of the plastic packaging film, avoiding excessive moisture on the surface of the plastic packaging film that cannot be dried by heating.

The hydraulic press 4 drives the clamping assembly to lift and lower through the output shaft. The lifting and lowering of the clamping assembly drive the plastic packaging film to lift and lower, changing the distance between the plastic packaging film and the hot air blower 12, adjusting the heat transfer of the hot air blown by the hot air blower 12 to the plastic packaging film, and controlling the attenuation of the flowing distance of the hot air blown in the air, so as to improve the drying efficiency control of the plastic packaging film.

[0032] Working principle: Place the plastic packaging film between the two fixed rollers 11 at both ends. One of the fixed rollers 11 rotates with the help of a motor, pulling the plastic packaging film towards the fixed roller 11 on the motor side. At this time, the hot air blower 12 arranged diagonally heats the surface of the plastic packaging film with hot air to raise the temperature of the surface of the plastic packaging film, thereby evaporating the moisture on the surface of the plastic packaging film. By heating intermittently on both sides, it is avoided that the same surface of the plastic packaging film is heated for too long, resulting in breakage or faults. The output shaft of the cylinder 32 pulls one end of the first transmission block 33 to rotate. The rotation of the first transmission block 33 drives the gear 5 to rotate. The two gears 5 are meshed with each other. The gear 5 drives the second transmission block 34. The first transmission block 33 and the second transmission block 34 rotate towards each other and drive the clamping plate 3. The plastic packaging film passes between the clamping plates 3. The clamping plates 3 scrape off the residual moisture on the surface of the plastic packaging film to prevent excessive moisture on the surface of the plastic packaging film from not being dried by heating. The clamping plates 3 heat the surface of the plastic packaging film through the internal heater to avoid the rapid drop in temperature of the plastic packaging film after passing through one hot air blower 12 due to the excessive distance between the two groups of hot air blowers 12, resulting in poor drying effect. The hydraulic press 4 drives the clamping assembly to lift through the output shaft. The lifting of the clamping assembly drives the plastic packaging film to lift, changing the distance between the plastic packaging film and the hot air blower 12, adjusting the heat transfer of the hot air blown out by the hot air blower 12 to the plastic packaging film, and controlling it by using the attenuation of the flowing distance of the hot air blown out in the air, so as to improve the control of the drying efficiency of the plastic packaging film.
