Description

Technical Field

[0001] The utility model relates to the field of bubble rollers, in particular to a bubble roller device for high-speed production. Background Art

[0002] Now the express delivery industry is developing very rapidly. Almost everyone likes to buy things online. After our things are mailed, they are usually wrapped with bubble film to prevent them from being damaged during transportation. Because bubble film is light in texture, waterproof and drop-proof, it is the first choice for packaging materials; the existing bubble film is generally a double-layer single-sided bubble film (one side is a bubble layer, the other side is a flat film layer). This bubble film is a light, transparent, non-toxic and tasteless plastic packaging material. The double-layer single-sided bubble film is also the bubble film with the largest usage and the cheapest price. As a packaging material, it is usually necessary to print product information on the surface of the packaging material. Since printing directly on the surface of the bubble film by an ordinary plastic film printing device will crush the bubbles and the printing is not clear, the current bubble film mainly adopts a medium printing method, first printing the printing layer on the medium layer, and then bonding the medium layer to the bubble film by heat sealing or bonding, and finally achieving the printing effect.

[0003] The existing Chinese utility model patent with publication number CN211000443U discloses a medium-free printed bubble film production equipment, whose main structure includes a bubble film production device, a printing device and a drying device. The printing device is located on the side of the bubble film forming roller surface with material in the bubble film production device. Since the bubble film layer being formed is protruded inside the bubble film forming roller, the pressure is uniform when the bubble film forming roller and the printing roller extrude the plastic template and the protrusion will not be crushed. The ink can be evenly attached to the surface of the flat film layer, so that the text or pattern of the printed layer is clear; by directly printing on the flat film layer surface of the bubble film during the production of the bubble film, the bubble film with the printed layer is produced and formed at one time, and the printed layer is firmly attached and clear; the production equipment is advanced, the operation process is simple, the production efficiency is high, the resources are saved, and the application environment is friendly.

[0004] In the above technical solution, the bubble film production equipment is indispensable to be set as a bubble film forming roller. The existing bubble film forming roller includes a roller core and a roller shaft fixedly connected to both ends of the roller core. The existing roller core is manufactured by assembling two steel cylinders in a fixed sleeve manner, wherein a plurality of airway partitions are machined on the outer peripheral surface of the inner steel cylinder, and then sleeved in the outer iron barrel to form a plurality of negative pressure airways, and finally bubble forming holes and small air holes are machined on the surface. In actual use, such bubble film forming rollers have the following problems:

[0005] 1. The bubble roller is generally made of steel or iron, which is heavy. The manufacturing process is very cumbersome and inefficient. At the same time, under the existing structure, the cooling water in the bubble film forming roller needs to be filled to the inner wall in the center. In order to ensure that the negative pressure airway has sufficient negative pressure suction, the outer cylinder needs to have a large enough diameter to mass produce bubble molds, so the cooling water space circulating in the inner cylinder needs to be particularly large. This makes the cooling water consumption of the bubble roller huge, and the bubble film forming roller in the upper space cannot be cooled in time, and the bubble film after forming cannot be efficiently cooled, resulting in low processing efficiency of the bubble film.

[0006] 2. In the prior art, when the bubble roller rotates, only the roller core rotates, and the outer suction disk does not move. The suction disk is only provided with a suction port to generate negative pressure for each negative pressure airway that rotates to the suction port. However, after the bubble film passing through the suction port is formed, due to the influence of the cooling water structure, the temperature is not cooled in time, resulting in a long time for cooling before demolding. If the speed of the bubble roller is forcibly increased, the uncooled bubble film will be peeled off in a sticky state, resulting in the rupture of bubbles on the bubble film, affecting the yield and causing the entire equipment to be unable to achieve high-speed production. Therefore, a set of effective cooling solutions is urgently needed to quickly cool the formed bubble film, thereby achieving rapid demolding and high-speed production. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a bubble roller device for high-speed production in view of the deficiencies of the above-mentioned prior art.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-speed production bubble roller device, comprising a roller core and a main shaft arranged on both sides of the roller core, the outer circumferential surface of the roller core is provided with a plurality of bubble forming holes along the circumferential direction, the inner wall of the roller core is provided with a plurality of circumferentially arranged air channels, the bubble forming holes are provided with a plurality of small air holes that are mutually connected with the air channels, and the characteristic is that: at least one cover plate that is relatively stationary with the roller core is provided on the side of the roller core, and the cover plate is provided with suction holes and blowing holes at intervals along the rotation direction of the roller core, the suction holes and the blowing holes are correspondingly arranged on the circumferential line of the air channel, and act on the air channel as the roller core rotates.

[0009] By adopting the above technical scheme, the bubble forming holes can be circular, square, triangular, polygonal and other structures. The suction holes and the blowing holes are correspondingly arranged on the circumference of the air channels. When the roller core rotates, different air channels are acted on. After the suction holes are connected to the air source from the outside of the cover plate, they act on multiple air channels above. After the blowing holes are connected to the air source from the outside of the cover plate, they act on multiple air channels below. When the roller core rotates, the air channels will enter the area of ​​the suction holes and the blowing holes one by one and communicate with them, so that the roller core inhales air at the top, adsorbs the bubble film to be formed into the bubble forming holes, and then heat-melts with the outer film to form a bubble film. However, the bubble film needs a long time to cool down before it can be demolded. Therefore, a blowing hole is arranged below the rotation direction of the roller core. The formed bubble film will enter the action range of the blowing hole below as the roller core rotates. While the blowing hole blows air to cool it down at a high speed, it also assists the formed bubbles to blow out of the bubble forming holes, thereby achieving rapid shaping and demolding, thereby ensuring that the roller core can rotate faster and efficiently produce bubble films.

[0010] The above-mentioned high-speed production bubble roller device can be further configured as follows: one end of the air blowing diffusion chamber along the rotation direction of the roller core is provided with a narrow air tube with a gradually increasing inner diameter.

[0011] By adopting the above technical solution, when the newly formed bubble film is rotated, the air volume at the rotating end is first small and then gradually increases, thereby avoiding direct demoulding of the bubble film at the end without cooling, resulting in rupture of the bubble film and stable demoulding.

[0012] The above-mentioned high-speed production bubble roller device can be further configured as follows: an end of the cover plate corresponding to the airway is provided with an air intake diffusion chamber connected to the air intake hole, and the air intake diffusion chamber is configured to be an arc shape and is arranged along the circumferential line direction of the airway; an end of the cover plate corresponding to the airway is provided with a blowing diffusion chamber connected to the blowing hole, and the blowing diffusion chamber is configured to be an arc shape and is arranged along the circumferential line direction of the airway.

[0013] By adopting the above technical scheme, the air suction diffusion chamber on the inner side of the cover plate acts on multiple air channels. After the blowing holes are connected to the air source from the outer side of the cover plate, the air suction diffusion chamber on the inner side of the cover plate acts on multiple air channels. Both the air suction diffusion chamber and the blowing diffusion chamber are set to be arc-shaped to match the roller core. When the roller core rotates, the air channels will enter the area of ​​the air suction diffusion chamber and the blowing diffusion chamber one by one and communicate with them, thereby realizing the effect of the large aperture on multiple air channels after the small aperture is connected, and realizing multi-range bubble forming and cooling demolding.

[0014] The above-mentioned high-speed production bubble roller device can be further configured to: also include a spoiler arranged on one side of the roller core, the spoiler is arranged on the side close to the blowing hole, the spoiler is bent toward the side of the roller core to form an arc shape, and cooperates with the blowing hole to form an air vortex between the bubble forming hole and the spoiler.

[0015] By adopting the above technical solution, the air blown out from the suction hole assists the bubble film to peel off the roller core, while the bubble forming hole after peeling is still within the range of the blowing hole, and blows air outwards and cooperates with the spoiler back to form an air vortex, which cools down the inner wall of the bubble film, achieves further cooling, and quickly demolds to accelerate production.

[0016] The above-mentioned high-speed production bubble roller device can be further configured as follows: the roller core has an inner core at the center, and a plurality of cooling cavities equidistantly distributed around the inner core are opened between the inner core and the bubble forming hole. The cooling cavities are against the outer walls of the bubble forming holes and are independently arranged with each other. Cooling circulation mechanisms are provided at both ends of the roller core for passing cooling medium into the cooling cavities for circulation.

[0017] By adopting the above technical scheme, a plurality of independent cooling chambers are arranged. The arrangement of the cooling chamber allows cooling water to directly act on the surface of the roller core at the corresponding position to achieve rapid lowering after it is passed into the cooling chamber, thereby improving the foundation for subsequent rapid demolding and thus achieving high-speed production. At the same time, the cooling water can be saved and overflow into the entire cooling chamber to directly cool the outer wall of the roller core, thereby reducing the amount of cooling water used and improving the cooling efficiency. This avoids the problem in the previous technology that only the bubble film below is cooled and the cooling efficiency above is too low. By arranging cooling circulation mechanisms on both sides, the cooling circulation mechanisms supply water to the multiple cooling chambers for cooling, thereby realizing cooling water circulation.

[0018] The above-mentioned high-speed production bubble roller device can be further configured as follows: the cooling circulation mechanism includes at least one main shaft seat connected to the inner wall of the roller core at the inner core corresponding to the roller core, and a water supply cavity that is mutually conductive with the cooling cavity is provided between the main shaft seat and the inner core, and the main shafts are all arranged on the main shaft seat, and a water inlet is provided inside to allow the cooling medium to enter the water supply cavity.

[0019] By adopting the above technical solution, water supply chambers are set on both sides to make the water supply chamber and the cooling chamber connected. When the bubble film is subsequently formed, the cooling water enters the water supply chamber on the other side through the cooling chamber from the water supply chamber at one end and then returns to the cooling water station. The cooling water circulation can be conveniently realized, the temperature can be quickly cooled, and the inlet and outlet at both ends can be realized. The cooling chamber is completely filled with cooling water, thereby efficiently cooling down.

[0020] The above-mentioned high-speed production bubble roller device can be further configured as follows: the inner core is hollow, and water-blocking plates are provided at both ends to seal the inner core.

[0021] By adopting the above technical solution, the hollow inner core is used to reduce the cost of raw materials, make the roller core lighter, reduce energy consumption, increase the processing speed, and seal the inner core by welding the water-blocking plate to prevent the entry of cooling water.

The blowing holes 32, the suction holes 31 and the blowing holes 32 are correspondingly arranged on the circumference of the air passages 12. When the roller core 1 rotates, they act on different air passages 12. After the suction holes 31 are connected to the air source from the outside of the cover plate 3, they act on multiple air passages 12 through the suction diffusion chamber 311 on the inside of the cover plate 3. After the blowing holes 32 are connected to the air source from the outside of the cover plate 3, they act on multiple air passages 12 through the blowing diffusion chamber 321 on the inside of the cover plate 3.

When the roller core 11 rotates, the air channels 12 will enter the area of ​​the suction diffusion chamber 311 and the blowing diffusion chamber 321 one by one and be connected with them, and a spoiler 4 is provided on one side of the roller core 1 to spoil the air flow. The plate 4 is arranged on the side close to the blowing hole 32, and the spoiler 4 is bent toward the side of the roller core 1 to form an arc shape, and cooperates with the blowing hole 32 to form an air vortex between the bubble forming hole 11 and the spoiler 4, that is, the suction hole 31 blows out the air to assist the bubble film to peel off the roller core, and the bubble forming hole 11 after peeling is still within the range of the blowing diffusion chamber 321, and blows outwards and cooperates with the spoiler 4 back to form an air vortex, which cools down the inner wall of the bubble film, achieves further cooling, and quickly demolds to accelerate production.

[0030] like Figure 1-Figure 6As shown, the roller core 1 has an inner core 13 at the center, and a plurality of cooling cavities 14 are provided between the inner core 13 and the bubble forming hole 11 and are equidistantly distributed around the inner core 13. The cooling cavities 14 are against the outer wall of the bubble forming hole 11 and are independently arranged. The inner core 13 is hollow and has water baffles 5 at both ends. The hollow inner core 13 is used to reduce the cost of raw materials, make the roller core 1 lighter, reduce energy consumption, and increase processing speed. Two spindle seats 6 connected to the inner wall of the roller core 1 are provided at the roller core 1 corresponding to the inner core 13, and a water supply cavity 15 that is mutually conductive with the cooling cavity 14 is provided between the spindle seat 6 and the inner core 13. The spindles 2 are all arranged on the spindle seat 6, and a water inlet 21 is provided inside to allow the cooling medium to enter the water supply cavity 15, and in the two After a water-blocking plate 5 is set at the end, the inner core 13 is closed to prevent cooling water from entering the inner core 13, and cooperates with the main shaft seat 6 to form a water supply chamber 15 at both ends of the shaft core 1. The cooling water enters the water supply chamber 15 from the water port 21 at one end, and enters the water supply chamber 15 on the other side through the cooling chamber 14 and then returns to the cooling water station through the water port 21, thereby realizing cooling water circulation and rapid cooling. The cooling chamber 14 is changed from the original center to an independent cooling chamber 14, so that the cooling water can be saved and overflow into the entire cooling chamber 14 to directly cool the outer wall of the roller core 1, thereby reducing the use of cooling water and improving the cooling efficiency, thereby avoiding the problem in the previous technology that only the bubble film below is cooled and the cooling efficiency above is too low.

[0031] When the high-speed bubble roller device of the utility model is used on a bubble film forming machine, the inner core 13 of the finished roller core 1 after processing is sealed by welding the water-blocking plates 5 at both ends of the inner core 13, and then the spindle seat 6 is covered, and it is ensured that the spindle seat 6 and the roller core 1 are sealed and fixed, and the cooling chamber 14 and the water supply chamber 15 are mutually connected, and then the cover plate 3 is covered, and the air suction holes 31 and the air blowing holes 32 of the cover plate 3 correspond to the processing rotation direction of the roller core 1 respectively, and then the water ports 21 at both ends of the spindle 2 are connected to the cooling system, and the cooling water circulates through the independent cooling chamber 14 to quickly act on the roller core 1, and the bubble film forming machine is started, the roller core 1 rotates, and the cover plate 3 does not move. The suction holes 31 and the blowing holes 32 on the cover plate 3 work to form negative pressure suction and positive pressure blowing, and negative pressure suction is applied to the air channel 12 in the roller core 1 that passes through the action area of ​​the suction holes 31 to form bubbles. Then the formed bubbles rotate with the roller core 1 and enter the action area of ​​the blowing holes 32 below for blowing. After blowing, the bubbles are cooled faster and blown out of the bubble forming holes 11. At the same time, part of the bubble forming holes 11 facing the spoiler 4 will be blown toward the spoiler 4 by the gas and then returned, forming an air vortex in between, which assists in further cooling and rapid demolding of the bubble film, and cooperates with the optimized cooling chamber 14 for rapid cooling and demolding, thereby realizing high-speed bubble film forming processing.
