Description

Technical Field

[0001] The utility model belongs to the technical field of plastic film blowing machines, and in particular relates to a fully automatic film blowing machine. Background Art

[0002] The film blowing machine heats and melts plastic particles and then blows them into a film. During the operation of the film blowing machine, the plastic particles are heated and melted and then extruded by the extrusion mechanism. The blower assembly and the die head assembly are used to blow the plastic body into a certain shape. The top is gathered by the mold clamping rod, and finally it is pulled by a traction machine at a certain speed. The winder winds it up and finally makes a finished film of the heat shrink tubing.

[0003] However, in the process of preparing finished film products, there are still the following obvious technical problems:

[0004] (1) After the hot melt raw material is blown into film, the long cylindrical heat shrink tubing will be suspended in the air under the action of the wind from the blower. At this time, the heat shrink tubing needs to be shrunk and flattened to form a two-layer film structure. However, the existing plastic film blowing machine directly uses two adjacent rollers to complete the above process during the shrinking and flattening process, which results in the shrinking and flattening of the heat shrink tubing being very prone to wrinkles. That is, the surface flatness of the heat shrink tubing is low, resulting in the poor quality of the produced heat shrink tubing.

[0005] (2) The traditional heat shrink tubing film thickness device cannot uniformly adjust the film thickness during the control process, resulting in uneven thickness of the film during processing, causing damage to the film during the film forming process, thereby affecting the production quality of the film and causing losses to the manufacturer's economic benefits;

[0006] (3) In the final reeling process, the traditional practice is to reel the heat shrink tubing onto a single reel and manually pause the machine when the reel is full. However, the workers are often busy and drag the heat shrink tubing onto the ground after the reel is full, causing product contamination. In addition, the workers have to judge whether the reel is full by themselves, which can easily lead to different lengths of each reel, low efficiency, and increased labor costs.

[0007] Therefore, this solution proposes a fully automatic film blowing machine, which can solve the above technical problems at the same time through the production line. Utility Model Content

[0008] The purpose of the utility model is to provide a fully automatic film blowing machine, which solves the technical problem of how to avoid wrinkles on the heat shrink tubing, ensures the flatness and uniformity of the heat shrink tubing, and realizes the automation and efficient replacement of the roller.

[0009] A fully automatic film blowing machine includes an extruder, a die head assembly for correction and shaping, a film blowing device, a shaping device, a clamping roller device and a winding device connected in sequence. The film blowing device is connected to an aeration component for blowing air into a heat shrink tubing. The shaping device includes a cold water shaping component 1, a hot water expansion component and a cold water shaping component 2 connected in sequence.

[0014] During specific operation, there will be air loss in the width of the heat shrink tubing before it is pulled to the clamping roller device after the aforementioned blowing. The reduced air volume causes the width of the heat shrink tubing to become smaller. If the width is lower than the error set by the system, the entire machine is controlled to reverse as a whole through the track (a power wheel is set at the bottom of the control box 2 to control the power wheel to move on the track). According to the servo distance set by the system, the heat shrink tubing is also pulled back and air is blown again to increase the overall width of the heat shrink tubing until the product is within the error range (automatic adjustment, reducing material loss and no need to stop the machine, to ensure the continuity of the finished product).

[0015] The first clamping roller assembly includes a lower clamping roller and an upper clamping roller arranged in parallel with each other, a lower support seat connected to the first lower clamping roller, an upper support seat connected to the first upper clamping roller, and a lifting mechanism connected to the first upper support seat;

[0020] A guide roller assembly is provided on the fixed frame, and one end of the heat shrinkable sleeve passes through the guide roller assembly and sequentially passes around one of the winding assemblies, one of the cutting mechanisms and / or one of the supporting assemblies to be connected to another adjacent winding assembly.

[0027] The beneficial effects of the present invention are as follows:

[0028] (1) It is equipped with a clamping roller assembly 1, a clamping roller assembly 2 and an image acquisition module, which can be used with a blast assembly to take pictures of the heat shrink tubing. The picture data is transmitted to the automation equipment in real time to measure whether the width of the finished product is within the range set by the system;

[0029] If the width is lower than the error set by the system, the entire clamping device will be controlled to pause first. After 3 seconds, the clamping device will change its running direction and rewind the heat shrink tubing according to the servo distance set by the system to re-blow air, increasing the overall width until the product is within the error range. This achieves automatic adjustment, reduces material loss and does not require shutdown, ensuring the consistency of the finished product.

[0030] (2) The heat shrink tubing is pulled to the winding device, where it is wound into a final product. The winding device here can be vertical or table-type. The winding device in this solution is provided with four reels. After a certain length is set, the second reel will take over from the first reel to receive the product.

[0057] The specific working process of this utility model:

[0058] What needs to be explained in this scheme is that the extruder, the die head assembly for correction and shaping, the film blowing device, and the shaping device are connected in sequence, the film blowing device is connected to the air filling assembly for blowing air into the heat shrinkable sleeve 4, and the shaping device includes a cold water shaping assembly 1, a hot water expansion assembly and a cold water shaping assembly 2 connected in sequence. These are all existing technologies and will not be described in detail here or shown in the accompanying drawings. They are hereby explained; the innovation of this scheme lies in the clamping roller device and the winding device, and its main technical features and working process are explained with respect to these two.

[0059] A clamping roller assembly 1 5, a clamping roller assembly 2 6 and an image acquisition module 11 are provided, which cooperate with the blast assembly to take pictures of the heat shrinkable tube 4. The picture data is transmitted to the automation equipment in real time to measure whether the width of the finished product is within the range set by the system;

[0060] If the width is lower than the error set by the system, the entire machine is controlled to reverse as a whole through track 1 (a power wheel is set at the bottom of the control box 2 to control the power wheel to move on track 1), and the heat shrink tube 4 is also pulled back and re-blown according to the servo distance set by the system to increase the overall width of the heat shrink tube 4 until the product is within the error range (automatic adjustment, reducing material loss and no need to stop the machine, can ensure the consistency of the finished product).

[0061] The heat shrinkable tube 4 is pulled to the winding device, where it is wound into a final product. The winding device here can be vertical or desktop. In actual operation, an upper support roller and a lower support roller are set on the fixed frame. The heat shrinkable tube 4 passes between the upper support roller and the lower support roller, bypasses one of the winding assemblies 8, one of the cutting mechanisms 10 and / or one of the supporting assemblies 9, and is connected to another adjacent winding assembly 8. It is then wound by the other winding assembly 8. After the heat shrinkable tube 4 is fully wound, the cutting mechanism 10 between the two winding assemblies 8 cuts the heat shrinkable tube 4. After cutting, the cutting knife is quickly retracted into the long through hole 123.

[0062] At this time, the heat shrinkable tube 4 falls under gravity into one of the winding assemblies 8 passing by. At this time, the winding assembly 8 is in rapid rotation. The suction pipe 82 and the suction pump are used to quickly suck the heat shrinkable tube 4 so that the fine holes on the outside of the reel suck the heat shrinkable tube 4 and make it adhere tightly to the reel. Finally, the heat shrinkable tube 4 is rewound onto the reel, completing the switch from the other winding assembly 8 to one of the winding assemblies 8.

[0063] Specifically, a plurality of winding assemblies 8 are provided on the rotating plate 12, and the rotating plate 12 is also connected to the driving structure. The plurality of winding assemblies 8 and the driving structure cooperate with each other. When the winding in one of the winding assemblies 8 is fully wound, the heat shrinkable tube 4 is quickly cut, and then the rotating plate 12 is quickly rotated by the driving structure, so that the next adjacent winding assembly 8 quickly rolls up the heat shrinkable tube 4 and performs the next winding process, and this cycle is repeated continuously.

[0064] A support assembly 9 is provided to support the thermoplastic sleeve during movement, so as to facilitate the quick separation of the heat shrinkable sleeve 4 from the previous winding assembly 8 after cutting, so as to allow efficient bonding and winding with the next winding assembly 8;

[0065] A cutting mechanism 10 is provided. Through the combined action of the telescopic cylinder and the cutting knife, the cutting knife is extended into the long through hole 123. The thermoplastic sleeve crosses through the long through hole 123 and also crosses the cutting knife. The cutting process is realized by extending the cutting knife, which is convenient and quick.

[0066] The technical features not described in the present invention can be realized by or by adopting the existing technology, and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
