Description

Technical Field

[0001] This utility model relates to the field of steam shrink machine technology, specifically a steam shrink machine. Background Technology

[0002] Steam shrink wrappers, also known as heat shrink film machines, use a steam generator to transfer heat from water to labels or heat shrink film on bottles and cans through nozzles. This causes the labels or heat shrink film to shrink due to the heat. Compared to other machines, steam shrink wrappers can increase the area of ​​the label or heat shrink film that is heated, thus improving the shrinkage effect and quality. However, when using steam shrink wrappers, water droplets will form on the surface of the label or heat shrink film because the heat is transferred by water vapor. Often, workers need to wipe the water droplets dry before packaging, which is time-consuming and labor-intensive.

[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] Example 1

[0024] Please see Figure 1-4A steam shrinking machine includes a support platform 1, a conveying unit 2, and a steam shrinking unit 3. The support platform 1 is connected to the ground, the conveying unit 2 is connected to the support platform 1 and arranged along the length of the support platform 1, and the steam shrinking unit 3 is connected to the support platform 1. The length of the steam shrinking unit 3 extends along the length of the support platform 1 and is located above the conveying unit 2. The two ends of the steam shrinking unit 3 along its length are an inlet 33 and an outlet 34, respectively. The support platform 1 is provided with symmetrically arranged water suction rollers 4, which are located on both sides of the outlet 34. The outer peripheral wall of the water suction rollers 4 is in contact with the material on the conveying unit 2. The support platform 1 is also provided with a squeeze roller 5 that is in contact with the water suction rollers 4. The water suction rollers 4 are used to absorb water droplets from the surface of the material at the outlet 34, and the squeeze roller 5 is used to squeeze the water absorbed by the water suction rollers 4.

[0025] It should be noted that the material in this embodiment is an example of a cylindrical bottle, and the label is made of a heat-shrinkable material, which is well known to those skilled in the art.

[0026] In practical applications, workers place labels on materials, and then the labeled materials are conveyed one by one from inlet 33 to steam shrink unit 3 via conveyor unit 2. Steam shrink unit 3 is continuously filled with steam, ensuring uniform heating of every part of the material, improving the label shrinkage effect, and allowing the label to adhere to the outer periphery of the material. The material passing through steam shrink unit 3 is then conveyed out from outlet 34 via conveyor unit 2. At outlet 34, water-absorbing roller 4 absorbs moisture from the label surface or material surface after shrinkage. The material contacts the water-absorbing roller 4 at outlet 34. The material is continuously conveyed by the conveying unit 2, causing rolling friction between the material and the suction roller 4. This means the material rotates, driving the suction roller 4 to rotate as well. Therefore, after passing through the suction rollers 4 on both sides, the water on the material can be absorbed. However, since the suction roller 4 has an upper limit on the amount of water it can absorb, the absorption effect will decrease when too much water is absorbed. Therefore, the squeeze roller 5 can squeeze out the water absorbed by the suction roller 4, thereby ensuring the absorption effect of the suction roller 4 and allowing it to work continuously. This is suitable for production line work scenarios. As a preferred embodiment, a power source, such as a motor, can be added to the suction roller 4.

[0027] Preferably, the support platform 1 is provided with a locking block 11 and a guide rod 12. The locking block 11 is fixedly connected to the support platform 1, and the guide rod 12 is connected inside the locking block 11. The guide rod 12 is arranged along the width direction of the support platform 1. The locking block 11 locks the guide rod 12 to the support platform 1. The ends of the squeezing roller and the extrusion roller 5 are rotatably connected to the guide rod 12.

[0028] Through the above design, the guide rod 12 can guide the position of the material, and the locking block 11 can lock the guide rod 12 onto the support platform 1. The operator can adjust the position of the guide rod 12 according to the size of the material. When the material passes through the outlet 34 between the guide rods 12, the material will come into contact with the water absorption roller 4. The water absorption roller 4 can absorb the moisture on the surface of the material. The water absorption roller 4 and the squeezing roller 5 can continuously absorb the moisture on the surface of the material, avoiding water droplets remaining on the surface of the material. On the other hand, in order to ensure the absorption effect of the water absorption roller 4, the water absorption roller 4 is designed to protrude from one side of the guide rod 12. This will cause the material to be resisted when passing between the water absorption rollers 4. However, as the subsequent material is conveyed, the next material will push the material stuck between the water absorption rollers 4 forward under the conveying action of the conveying unit 2. Since the guide rod 12 restricts the movement of the material between the guide rods 12, the design of the guide rod 12 can also prevent the material from getting stuck between the water absorption rollers 4.

[0029] Preferably, the locking block 11 includes a locking seat 111 and a locking rod 112. The locking seat 111 is fixedly connected to the support platform 1. The locking seat 111 is provided with a locking groove 1111. The locking rod 112 is arranged through the locking groove 1111. The guide rod 12 is connected in the locking groove 1111. The guide rod 12 can be locked in the locking seat 111 by the locking rod 112.

[0030] In the above design, the locking seat 111 is fixed on the support platform 1 by bolts, while the guide rod 12 can pass through the locking groove 1111 and be locked to the locking seat 111 by the locking rod 112. In this embodiment, the locking rod 112 is a bolt. The operator can adjust the position of the guide rod 12 by loosening the locking rod 112, so as to accommodate more materials of different sizes, and lock it by the locking rod 112.

[0031] Preferably, the support platform 1 is provided with a bracket 13, a rotating shaft 14, and a drive motor 15. The bracket 13 is connected to both sides of the support platform 1, the drive motor 15 is connected to the support platform 1, the output end of the drive motor 15 is fixedly connected to the rotating shaft 14, the rotating shaft 14 is rotatably connected to the bracket 13 and located above the conveying unit 2, and a plurality of striking bars 141 are provided on the outer peripheral wall of the rotating shaft 14.

[0032] With the above design, after the staff puts the label on the material, it is conveyed by the conveying unit 2. However, since the bottom of some labels is not flush with the bottom of the material, the position of the labels is not ideal after passing through the steam shrinking unit 3. Therefore, the bottom of the label can be aligned with the bottom of the material by the rotating shaft 14 and the striking bar 141. The striking bar 141 is made of soft material. In this embodiment, the striking bar 141 is made of rubber. The rotating shaft 14 is driven by the drive motor 15 to rotate counterclockwise, so that the striking bar 141 can strike the bottom of the label from top to bottom to the bottom of the material, that is, to make the bottom of the label flush with the bottom of the material, thereby improving the effect of the label shrinkage.

[0033] Preferably, the steam shrinkage unit 3 includes a support base 31 and a steam generator 32. The steam generator 32 is connected to the ground and located below the support platform 1. The support base 31 is connected to the support platform 1 and located above the steam generator 32. The support base 31 is provided with a through shrinkage channel 311. The shrinkage channel 311 is arranged along the conveying direction of the conveying unit 2. The output end of the steam generator 32 is connected to the shrinkage channel 311.

[0034] In the above design, the labeled material enters the support base 31 from the inlet 33 through the conveying unit 2, more specifically into the shrinkage channel 311, and the steam generator 32 continuously supplies steam into the shrinkage channel 311, so that the entire bottle of the labeled material can be heated evenly, improving the quality of label shrinkage. The steam generator 32 summarized in this embodiment can be referred to the steam generator 32 in Chinese patent document CN222408834U, which will not be described in detail here.

[0035] Preferably, curtains 312 are provided at both ends of the support base 31.

[0036] In this embodiment, the two ends of the support base 31 are the inlet 33 and the outlet 34, respectively. That is to say, there is a curtain 312 at the inlet 33 and the outlet 34. The curtain 312 can prevent steam from escaping and can concentrate it more in the shrink channel 311, thereby improving the quality of label shrinking.

[0037] Preferably, the support platform 1 is provided with a water receiving trough 16, which is located below the conveying unit 2. On the projection along the height direction of the support platform 1, both the squeezing roller 5 and the water suction roller 4 are located in the water receiving trough 16. The water receiving trough 16 is used to store the water squeezed by the squeezing roller 5 and the water suction roller 4.

[0038] Through the above design, the water receiving tank 16 can receive the water absorbed by the water suction roller 4 by the squeezing roller 5. On the one hand, the water receiving tank 16 can facilitate the recycling of water resources by the staff. On the other hand, the water receiving tank 16 can be connected to the water inlet of the steam shrink unit 3 to realize the recycling of water resources. The specific choice can be made flexibly according to the actual situation.

[0039] Preferably, the conveying unit 2 is a mesh belt conveyor.

[0040] In this embodiment, the conveying unit 2 is a mesh belt conveyor. The conveyor belt of the mesh belt conveyor has mesh holes, which facilitates the passage of steam and also allows the water squeezed by the squeezing roller 5 to fall from the mesh holes into the water receiving tank 16.
