Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle label wrinkle removal technology, specifically a bottle outer packaging wrinkle removal machine. Background Technology
[0002] Bottles, including plastic and glass bottles, require labeling machines to affix wraparound labels with production information after molding. Due to manufacturing processes, air bubbles or wrinkles sometimes inevitably exist between the wraparound label and the bottle body. Therefore, the wraparound label needs to be shrunk. The common practice is to use a steam shrink wrapper, which uses high-temperature steam to heat-shrink the label again to quickly eliminate wrinkles and improve label adhesion. However, in existing steam shrink wrappers, the high-temperature steam tends to escape quickly during label wrinkling, generally flowing upwards to the top of the machine where it condenses into water droplets. These water droplets accumulate and fall back onto the bottle, interfering with the wrinkle-removing effect of the high-temperature steam and reducing its effectiveness. Utility Model Content
[0003] The purpose of this invention is to provide a bottle outer packaging wrinkle removal machine that can form a relatively sealed space between the partition and the conveyor belt. The partition reduces the flow rate of high-temperature steam while slowing down steam loss. In addition, the gas collection hood guides some of the water droplets formed by the cooling of high-temperature steam to the outside of the conveyor belt, preventing water droplets from dripping onto the conveyor belt and interfering with the wrinkle removal of the bottle body. This solves the problem mentioned in the background art that the existing steam shrink machine is prone to steam loss and the water droplets formed by condensation interfere with the wrinkle removal of high-temperature steam.
[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0022] 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.
[0023] Please see Figure 1-2A bottle packaging wrinkle removal machine includes a frame 1 and a housing 2 mounted on top of the frame 1. The housing 2 has a cavity, and inlet and outlet ports are respectively opened at both ends of the housing 2 for bottles to enter and exit. A transport mechanism 3 is provided inside the housing 2. The transport mechanism 3 includes a conveyor belt 31 arranged horizontally along the length of the housing 2 for transporting bottles. One end of the conveyor belt 31 extends out of the inlet port, and the other end extends out of the outlet port. Several high-temperature steam nozzles 4 are arranged along the length of the conveyor belt 31 on both sides and above the conveyor belt 31. A partition net 5 is provided above the conveyor belt 31, and an inverted V-shaped gas collecting hood 6 is provided above the partition net 5, with both ends of the gas collecting hood 6 extending to the inner sidewall of the housing 2.
[0024] In use, the high-temperature steam nozzle 4 is connected to an external steam generator. The steam generator supplies high-temperature steam to the high-temperature steam nozzle 4, which then sprays the high-temperature steam onto the bottle body. The high-temperature steam nozzle 4 is a universal steam nozzle, and its nozzle direction can be adjusted up, down, left, and right to adjust the position of the high-temperature steam nozzle 4 towards the bottle. This allows it to adapt to the shrinkage of labels on bottles of different sizes, resulting in more uniform shrinkage of the label around the bottle and improving the shrinkage effect of the label.
[0025] This invention creates a relatively enclosed space between the partition net 5 and the conveyor belt 31 by setting a partition net 5 above the conveyor belt 31. The partition net 5 reduces the flow rate of high-temperature steam and slows down steam loss, thereby improving the wrinkle removal effect of high-temperature steam and making the bottle shrink more evenly around the label. The gas collection hood 6 guides some of the water droplets formed by the cooling of high-temperature steam to the outside of the conveyor belt 31 to prevent water droplets from dripping onto the conveyor belt 31 and interfering with the wrinkle removal of the bottle. The remaining high-temperature steam is cold-recovered and reused.
[0026] Please see Figure 1 as well as Figure 3 The transport mechanism 3 includes two upright and oppositely arranged side plates 32 on the bottom wall of the box body 2, a plurality of rollers 33 spaced along the length of the side plates 32 and rotatably connected to the two side plates 32 respectively, and a motor 34 mounted on one of the side plates 32. The conveyor belt 31 is wound around the plurality of rollers 33, and the output shaft of the motor 34 is drivenly connected to one of the rollers 33. In this embodiment, the two ends of the side plates 32 extend outside the box body 2 through the inlet and outlet respectively, and the motor 34 is mounted on the end of the side plate 32 extending out of the inlet.
[0027] Please refer to Figure 3-4A plurality of limiting protrusions 7 are provided on the top surface of the conveyor belt 31 along the length of the conveyor belt 31. A ring 71 is integrally formed on the outer circumference of the limiting protrusions 7, and a limiting groove 72 is formed between the inner circumference of the ring 71 and the outer circumference of the limiting protrusions 7. During conveying, the bottle mouth of an inverted bottle is fitted onto the limiting protrusion 7, and the lower end face of the bottle mouth abuts against the bottom surface of the limiting groove 72 to prevent high-temperature steam from entering the bottle. The ring 71 restricts the bottle mouth to the outside, which facilitates stable conveying when the bottle is inverted.
[0028] Please see Figure 2-3 Limit adjustment structures 8 are respectively provided on both sides of the conveyor belt 31. Each limit adjustment structure 8 includes a plurality of mounting plates 81 spaced apart along the length of the side plate 32, a slide rod 82 movably mounted on the mounting plate 81, and a limiting plate 83 connected to one end of the slide rod 82. The limiting plate 83 is located beside the top surface of the conveyor belt 31. A screw 84 is provided on the top surface of the mounting plate 81. The lower end of the screw 84 passes through the mounting plate 81 and abuts against the slide rod 82 to limit the sliding of the slide rod 82. During installation, the slide rod 82 can be slid left and right to adjust the limiting plates 83 on both sides of the conveyor belt 31 to a suitable position to accommodate bottles of different sizes. After adjustment, the slide plate is tightened by the screw 84. In this embodiment, the surface of the limiting plate 83 is covered with bristles. The bristles are used to assist in the shrinking of the surrounding label on the bottle by high-temperature steam. At the same time, the bristles can prevent scratches or abrasions caused when the side wall of the bottle comes into direct contact with the limiting plate 83.
[0029] Please see Figure 1-2 A steam recovery hood 21 is installed above both the inlet and outlet of the housing 2, and the steam recovery hood 21 is connected to a steam recovery pipe 22; the top of the gas collecting hood 6 is connected to a steam channel 61 that communicates with the steam recovery pipe 22. In this embodiment, the steam channel 61 is a long and narrow rectangular channel, and the high-temperature steam collected by the steam recovery pipe 22 is used to circulate and supply the high-temperature steam nozzle 4, thereby improving the utilization rate of high-temperature steam and reducing energy consumption.
[0030] Please see Figure 2 The bottle packaging wrinkle removal machine includes a support structure 9 disposed within a housing 2. The support structure 9 includes several columns 91 positioned opposite each other on the bottom wall of the housing 2, and a first support frame 91 connected to the upper part of the columns 91. Several high-temperature steam nozzles 4 are mounted on the first support frame 91. During the wrinkle removal process, high-temperature steam can pass between the first support frame 91 and the second support frame 92. A mesh 5 is laid on the first support frame 91, with both ends extending downwards to near the bottom wall of the housing 2. A steam chamber is formed between the mesh 5 and the conveyor belt 31. This steam chamber slows down the rate of steam loss and improves the shrinkage effect of the high-temperature steam on the bottle label.
[0031] The support structure 9 includes a second support frame 92 connected to the upper part of a plurality of columns 91 and located above the first support frame 91. In this embodiment, both the first support frame 91 and the second support frame 92 are inverted V-shaped and are arranged above the conveyor belt 31 along the length direction of the conveyor belt 31.
[0032] Please see Figure 2 A self-cleaning structure 10 is provided on the second support frame 92. The self-cleaning structure 10 includes a plurality of spray pipes 101 rotatably mounted on the second support frame 92, and the plurality of spray pipes 101 are located above the partition screen 5. In this embodiment, the spray pipes 101 are connected to an external high-pressure water pump, and the spray pipes 101 have evenly distributed water outlets. When the mesh opening of the partition screen 5 is blocked, the spray pipes 101 are opened to powerfully rinse the mesh opening of the partition screen 5. During this process, the spray pipes 101 can be rotated to different angles to clean different positions of the partition screen 5, so as to clean more thoroughly and avoid the high-temperature steam from not being able to escape upward due to the blockage of the mesh opening of the partition screen 5. When the high-temperature steam cannot escape upward, it will condense into water droplets, and the water droplets falling on the conveyor belt 31 will interfere with the wrinkle removal effect of the bottle.
[0033] Please see Figure 1-2 The bottom wall of the housing 2 is provided with water collection tanks 23 located below both ends of the gas collection hood 6. The water collection tanks 23 are used to collect water droplets formed by the condensation of high-temperature steam when it comes into contact with the gas collection hood 6. The bottom of the housing 2 is provided with a water storage tank 24 connected to the water collection tanks 23. The bottom of the water storage tank 24 is V-shaped. The water storage tank 24 is used to store and recycle the water droplets collected by the water collection tanks 23.
[0034] Please see Figure 1 as well as Figure 5 A preheating structure 11 is provided at the inlet of the housing 2. The preheating structure 11 includes a heating box 111 fixed on the housing 2 and heating pipes 112 arranged opposite each other on both sides inside the heating box 111. The heating pipes 112 are used to preheat the bottles, so that the high-temperature steam will not come into contact with the outer wall of the bottle and condense, thus preventing the outer wall of the bottle from getting wet and affecting the shrinkage and wrinkle removal effect. In this embodiment, the heating box 111 has openings on both sides for the conveyor belt 31 to pass through and communicate with the inlet.
[0035] In this embodiment, please refer to Figure 1 The two side walls of the enclosure are equipped with openable and closable inspection doors for easy maintenance later.
[0036] The working principle of this bottle outer packaging wrinkle removal machine is as follows: When shrinking and wrinkling the label around the bottle, the motor 34 starts and drives the conveyor belt 31 to move through the roller 33, inverting the bottle so that its mouth is fitted onto the limiting protrusion 7; the conveyor belt 31 carries the bottle and preheats it when it passes through the heating box 111. The conveyor belt 31 continues to move forward, and the bottle enters the box 2 through the feed port of the box 2. During this process, the high-temperature steam nozzle 4 sprays high-temperature steam onto the bottle, filling the steam chamber with high-temperature steam to remove wrinkles from the bottle; the high-temperature steam slowly flows upward through the partition 5, and the gas collection hood 6 guides some of the water droplets formed by the cooling of the high-temperature steam to the outside of the conveyor belt 31, and the remaining high-temperature steam is cold-recovered and reused through the steam channel 61. The dripping water droplets are collected by the water collection tank 23 into the water storage tank 24; the conveyor belt 31 continues to move forward, and the bottle is carried out of the box 2, and the wrinkle removal is completed; during the wrinkle removal process, some high-temperature steam also flows to the steam recovery hood 21 through the feed port and the discharge port respectively, realizing the high-temperature steam recovery and reuse.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
