Description

Technical Field

[0001] This application relates to the field of encapsulation technology, and in particular to an advertising design template encapsulation machine. Background Art

[0002] In order to facilitate the display of their own design styles to customers, some advertising design works will be pre-made into templates. And in order to use the templates multiple times, for example, for reference display to different customers or mailing as gifts, etc., the templates will also be selected for plastic packaging.

[0003] Existing plastic packaging equipment can use a conveyor belt to convey the template placed in the heat shrink film on the conveyor belt to a designated position, and then the heating cover that can heat the heat shrink film moves down to cover the template inside, and then the heating cover heats the inside to make the heat shrink film shrink due to heat, so as to achieve the encapsulation of the template. For example, a split plastic sealer with the publication number CN221776249U.

[0004] In view of the above related technologies, after one encapsulation is completed, the heating cover moves up to make the encapsulated template move forward. At this time, the air heated to a relatively high temperature inside the heating cover overflows, so that when encapsulating the next template, the air inside the heating cover needs to be reheated. And in order for the heating cover to adapt to the encapsulation operations of templates of different sizes, the internal space volume of the heating cover needs to be designed larger, resulting in a long re-heating time and low encapsulation efficiency. Summary of the Invention

[0005] In order to improve the encapsulation efficiency, this application provides an advertising design template encapsulation machine.

[0006] The advertising design template encapsulation machine provided by this application adopts the following technical solutions.

[0007] An advertising design template encapsulation machine includes a conveyor for conveying templates, and a heating cover that can cover the templates inside and heat the internal air to achieve the encapsulation of the templates. There is a gas-retaining plate at the bottom inside the heating cover that can close the upper middle part inside the heating cover, and a gas-retaining cylinder that can drive the gas-retaining plate to move out of or into the heating cover is detachably connected to the outside of the heating cover.

[0008] By adopting the above technical solutions, before the template is encapsulated and the heating cover moves away from the conveyor, the gas-retaining plate first closes the upper part inside the heating cover, and then the heating cover moves up, so that a part of the hot air inside the heating cover is retained. When encapsulating the next template, the air temperature inside the heating cover is not likely to be too low, so as to improve the heating speed of the air inside the heating cover and improve the encapsulation efficiency.

[0009] Optionally, at least two gas-retaining plates are provided, and the two gas-retaining plates can be attached to each other to close the heating cover.

[0010] By adopting the above technical solution, the volume of each of the two air-retaining plates exposed outside the heating cover does not need to be too large, and the moving path of the air-retaining plate can be shortened, so as to minimize the occupation of external volume as much as possible.

[0011] Optionally, a plurality of groups of the air-retaining plates are arranged along the height direction of the heating cover, and there are two in each group. An anti-pressure mechanism is provided between the power rod of the air-retaining cylinder and the air-retaining plate, which can prevent the air-retaining plate with a lower height from moving along with the operation of the air-retaining cylinder when the air-retaining plate abuts against the template. The friction coefficient between the adjacent surfaces of the two air-retaining plates in the same group is low.

[0012] By adopting the above technical solution, when the height of the template is relatively high, the two air-retaining plates with a lower height in the same group will abut against the template, and the two air-retaining plates with a higher height in the same group can still close the heating cover, so as to retain as much hot air in the heating cover as possible.

[0013] Optionally, the anti-pressure mechanism includes a rod block detachably connected to the power rod of the air-retaining cylinder, a guide rod fixedly connected to the rod block and inserted into the air-retaining plate, and a compression spring detachably connected between the rod block and the air-retaining plate to force the air-retaining plate to move towards the inside of the heating cover.

[0014] By adopting the above technical solution, when the air-retaining plate with a lower height abuts against a relatively high template, the air-retaining plate is not likely to exert too much pressure on the template.

[0015] Optionally, an end block is fixedly connected to one end of the guide rod located inside the air-retaining plate. The air-retaining plate is detachably connected with a guide ring sleeved thereon and for the guide rod to slide through, and the guide ring can abut against the end block.

[0016] By adopting the above technical solution, the guide rod is not likely to be separated from the air-retaining plate due to the acting force of the compression spring.

[0017] Optionally, at least one row of plate surface rollers are rotatably connected to the adjacent surfaces of the two air-retaining plates in the same group, and the plate surface rollers can be attached to the surface of the template.

[0018] By adopting the above technical solution, when the heating cover moves upward, due to the existence of the plate surface rollers, the relatively high template is less likely to be driven to move upward.

[0019] Optionally, the two rows of plate surface rollers corresponding to the two air-retaining plates in the same group are arranged in a staggered manner, and plate surface holes for the plate surface rollers to enter are formed in the adjacent surfaces of the two air-retaining plates in the same group.

[0020] By adopting the above technical solution, even when there are plate surface rollers, the two air-retaining plates can be closely attached when the two air-retaining plates are close to each other, so that when the heating cover moves upward and then moves downward again, the hot air in the heating cover is not likely to overflow too much.

[0021] Optionally, the heating hood includes a hood body that covers the template conveyed on the conveyor, an electric heater detachably connected to the inner wall of the top of the hood body, and a guiding fan detachably connected to the hood body and capable of sending air flow to the electric heater.

[0022] By adopting the above technical solution, the air flow in the hood body is accelerated, so as to improve the air heating efficiency in the hood body.

[0023] Optionally, crisscross belt surface channels are formed on the conveyor belt surface of the conveyor.

[0024] By adopting the above technical solution, the heat shrinkable film on the lower surface of the template is heated.

[0025] Optionally, the material of the conveyor belt of the conveyor includes any one or several of silica white, graphene, copper powder, aluminum powder and alumina powder.

[0026] By adopting the above technical solution, the heat conductivity of the conveyor belt of the conveyor is improved as much as possible, so that the heat shrinkable film on the lower surface of the template can be fully heated.

[0027] In summary, the present application has at least the following beneficial effects.

[0028] When performing the encapsulation work of multiple templates, the air temperature in the heating hood is not easily too low, so as to improve the heating speed of the air in the heating hood and improve the encapsulation efficiency. Description of the Drawings

Detailed Embodiment

[0032] The following further describes the present application in detail with reference to the drawings.

[0033] The embodiment of the present application discloses an advertising design template encapsulation machine. Refer to Figure 1, including a conveyor 1 for conveying a template covered with a heat-shrinkable film in a belt-like manner. There is a heating hood 2 directly above the conveyor belt of the conveyor 1. A cylinder can be detachably connected to the frame of the conveyor 1 to drive the heating hood 2 to move vertically, so that the heating hood 2 can move down to cover the template conveyed by the conveyor 1, heat the air in the heating hood 2, cause the heat-shrinkable film to shrink due to heat and tightly adhere to the template, and complete the encapsulation of the template.

[0034] Refer to Figure 1 and Figure 2 , the heating hood 2 includes a hood body 58, an electric heater 59 and a diversion fan 41. The diversion fan 41 is detachably connected to the inner top of the hood body 58 to continuously circulate the air inside the hood body 58. The electric heater 59 is detachably connected to the inner top of the hood body 58 and the heating part is directly below the air outlet of the diversion fan 41. At the same time, the surface of the conveyor belt of the conveyor 1 is densely formed with criss-cross belt surface channels 42, and the conveyor belt of the conveyor 1 is made of any one or several of silica white, graphene, copper powder, aluminum powder and alumina powder, so that the heat-shrinkable film at the lower surface of the template can also be smoothly shrunk due to heat.

[0035] Refer to Figure 1 and Figure 2 , air-retaining plates 3 are slidably connected to the opposite two vertical outer walls of the hood body 58. The air-retaining plates 3 are arranged in several groups and two in each group. In this embodiment, the air-retaining plates 3 are arranged in two groups. The two air-retaining plates 3 in the same group are at the same height. One group of air-retaining plates 3 is located in the upper middle of the hood body 58 and the other group of air-retaining plates 3 is located in the lower middle of the hood body 58. The moving direction of the air-retaining plates 3 is horizontal. The two air-retaining plates 3 in the same group can approach or move away from each other. The two approaching air-retaining plates 3 can close the hood body 58, so that when the hood body 58 needs to move up after the encapsulation of one template is completed, the heated air in the hood body 58 can leak out as little as possible. Two groups of two air-retaining cylinders 4 are detachably connected to the vertical outer wall of the hood body 58. An anti-pressure mechanism 5 is provided between the power rods of the two air-retaining cylinders 4 in the same group and the corresponding two air-retaining plates 3.

[0036] Refer to Figure 2, the anti-pressure mechanism 5 includes a rod block 51 detachably connected to the end portions of the power rods of two air-retaining cylinders 4 in the same group. The rod block 51 is fixedly connected with a guide rod 52 inserted into the air-retaining plate 3 along the sliding direction of the air-retaining plate 3. One end of the guide rod 52 located inside the air-retaining plate 3 is fixedly connected with an end block 54. The end block 54 is slidably connected inside the air-retaining plate 3. A guide ring 55 is detachably connected to the opening of the air-retaining plate 3 for the guide rod 52 to be inserted. The guide ring 55 can abut against the end block 54 so that the guide rod 52 is not easily separated from the air-retaining plate 3. A compression spring 53 that forces the air-retaining plate 3 to move towards the inside of the cover body 58 is detachably connected between the rod block 51 and the air-retaining plate 3. So that when the height of the template is relatively high, the two air-retaining plates 3 in the lower group will abut against the opposite sides of the template, while the two air-retaining plates 3 in the higher group can be smoothly closed to minimize the leakage of hot air in the cover body 58 as much as possible. And, the lengths of the guide rod 52 and the compression spring 53 only need to be 1 / 2 to 1 / 3 of the length of the air-retaining plate 3 moving in the cover body 58, that is, it can meet the movement of the guide rod 52 inside the air-retaining plate 3 when the air-retaining plate 3 abuts against the template.

[0037] Referring to Figure 2 , a row of plate surface rollers 56 are rotatably connected to the adjacent vertical surfaces of the two air-retaining plates 3 in the same group. The rotation axis of the plate surface rollers 56 is horizontal. The plate surface rollers 56 can fit against the surface of the template so that when the cover body 58 moves upward, the template is not easily driven to move upward. The two rows of plate surface rollers 56 of the two air-retaining plates 3 in the same group are arranged in a staggered manner. A row of plate surface holes 57 are opened on the surface of each air-retaining plate 3 where the plate surface rollers 56 are arranged. The plate surface holes 57 of one air-retaining plate 3 can allow the plate surface rollers 56 of the other air-retaining plate 3 to enter so that the two air-retaining plates 3 in the same group are not easily unable to fit tightly due to the existence of the plate surface rollers 56.

[0038] The implementation principle of an advertising design template encapsulation machine according to an embodiment of the present application is as follows: The cover body 58 moves downward to cover the template placed on the conveyor belt of the conveyor 1, and then the electric heater 59 and the diversion fan 41 operate to heat the air in the cover body 58 until a predetermined time. After that, the template is encapsulated. Then the air-retaining cylinders 4 operate to move the two groups of air-retaining plates 3 to close the cover body 58 so that during the upward movement of the cover body 58, the heated hot air in the cover body 58 is not easily leaked out too much.

[0039] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
