Description

Technical fields:

[0001] This utility model belongs to the technical field of paper cup packaging equipment, and specifically refers to a paper cup packaging equipment with an exhaust function. Background technology:

[0002] In the field of automated paper cup packaging, traditional equipment generally uses heat sealing to encapsulate multi-layered stacked paper cups within a plastic film to achieve moisture protection, dust prevention, and ease of storage and transportation. However, in actual packaging, traditional packaging equipment lacks an exhaust function. When the sealing and cutting components directly act on the surface of the packaging film for thermoforming, a sealed air cavity is formed between the plastic film and the multi-layered paper cup stack. This sealed air cavity contains a significant amount of air, causing the sealed plastic film to bulge partially or entirely due to the air pressure within the cavity. During transportation and storage, the bulging plastic film is easily ruptured by external pressure, causing the paper cups to be directly exposed to the outside environment and losing their hygienic protective function. Summary of the Invention:

[0003] The purpose of this invention is to provide a paper cup packaging device with a venting function. Before the existing sealing and cutting components perform thermoplastic operation, the device uses a venting telescopic source to push the packaging film into the mouth of the paper cup to effectively vent the air and reduce the size of the air cavity between the packaging film and the paper cup assembly. As a result, the packaging film does not bulge significantly after thermoplastic sealing and is less likely to be squeezed and broken.

[0004] This utility model is implemented as follows:

[0005] A paper cup packaging device with venting function includes a frame, a paper cup conveying platform for forward conveying of paper cup groups and enabling them to enter unsealed packaging film, and a sealing and cutting component for cutting and sealing the unsealed packaging film. The paper cup group includes one or more stacked paper cups with their openings facing away from the sealing and cutting component. A venting telescopic source is connected to the frame in front of the sealing and cutting component via a support frame. The telescopic end of the venting telescopic source is positioned towards the opening of the paper cup, and the telescopic end of the venting telescopic source can push part of the packaging film into the opening of the top layer of paper cup.

[0006] In the aforementioned paper cup packaging equipment with venting function, the support frame has an assembly strip-shaped through hole in the front-back direction, the venting telescopic source is fixed on the venting adjustment seat, and the venting adjustment seat can slide through the assembly screw and be relatively fixed on the assembly strip-shaped through hole.

[0012] In the aforementioned paper cup packaging equipment with venting function, the positioning adjustment seat includes a second horizontal adjustment support plate, a second vertical adjustment support plate, and a second mounting plate. The second horizontal adjustment support plate is connected to the second mounting strip-shaped through hole via assembly screws. The second horizontal adjustment support plate has a second horizontal strip-shaped through hole along its horizontal direction.

[0018] The present invention will be further described below with reference to specific embodiments. See below for details. Figure 1 :

[0019] A paper cup packaging device with venting function includes a frame 1, a paper cup conveying platform 4 for conveying paper cup groups 2 forward and into unsealed packaging film 3, and a sealing and cutting component 5 for cutting and sealing the unsealed packaging film 3. The paper cup group 2 includes one or more stacked paper cups with their openings facing away from the sealing and cutting component 5. A venting telescopic source 7 is connected to the frame 1, located in front of the sealing and cutting component 5, via a support frame 6. The telescopic end of the venting telescopic source 7 is positioned towards the opening of the paper cup, and this telescopic end can push part of the packaging film 3 into the opening of the top layer of paper cup. In this embodiment, a rubber pad 23 is fitted onto the telescopic end of the venting telescopic source 7.

[0020] This utility model has a simple structure, reasonable design and high economic benefits. Before the existing sealing and cutting component 5 performs thermoplastic operation, the packaging film 3 is pushed into the mouth of the paper cup by means of the exhaust telescopic source 7, so as to effectively exhaust the air and reduce the size of the air cavity between the packaging film 3 and the paper cup assembly 2. As a result, the packaging film 3 does not bulge significantly after thermoplastic sealing and is not easily squeezed and broken.

[0021] In order to adjust the front and rear position of the exhaust telescopic source 7 relative to the paper cup group 2 so that the exhaust telescopic source 7 can be applied to paper cup groups 2 composed of different stacked numbers of paper cup groups 2, the support frame 6 is provided with an assembly strip-shaped through hole 8 in the front and rear direction. The exhaust telescopic source 7 is fixed on the exhaust adjustment seat, and the exhaust adjustment seat can slide through the assembly screw and be relatively fixed on the assembly strip-shaped through hole 8.

[0022] Meanwhile, considering the different cup opening positions of paper cups of different sizes, the exhaust adjustment seat includes a horizontal adjustment support plate 9, a vertical adjustment support plate 10, and a mounting plate 11. The horizontal adjustment support plate 9 is connected to the mounting strip-shaped through hole 8 by mounting screws. The horizontal adjustment support plate 9 has a horizontal strip-shaped through hole 8. The vertical adjustment support plate 10 is slidable and relatively fixed to the horizontal adjustment through hole 8 by mounting screws. The vertical adjustment support plate 10 has a vertical strip-shaped through hole 8. The mounting plate 11 is slidable and relatively fixed to the vertical strip-shaped through hole 8 by mounting screws. The exhaust telescopic source 7 is connected to the mounting plate 11. That is, by means of the sliding engagement of the vertical adjustment support plate 10 on the horizontal strip-shaped through hole 8 and the sliding engagement of the mounting plate 11 on the vertical strip-shaped through hole 8, the horizontal and vertical position adjustment of the exhaust telescopic source 7 relative to the frame 1 can be realized.

[0023] Furthermore, in this embodiment, a pusher cylinder is provided on the rear side of the paper cup conveying platform 4 to push the paper cup group 2 forward on the paper cup conveying platform 4. That is, after the previous group of paper cups 2 is pushed into the packaging film 3 and heat-sealed, under the action of the pusher cylinder, the next group of paper cups 2 moves forward into the packaging film 3, and at the same time, it also pushes the previous group of paper cups 2 to continue to move forward, thereby realizing automatic and continuous packaging and sealing operation. Therefore, in order to enable the packaged paper cup group 2 to exit from the paper cup conveying platform 4 without being interfered with by the position of the exhaust telescopic source 7, a pusher telescopic source 12 and an unloading channel 13 are respectively provided on the frame 1 on the left and right sides of the paper cup conveying platform 4. The pusher telescopic source 12 is arranged laterally and its telescopic end is provided with a push plate 14. That is, the unloading telescopic source pushes the paper cup group 2 laterally into the unloading channel 13 through the push plate 14.

[0024] Furthermore, a vertical adjustment cylinder 15 is vertically arranged on the mounting plate 11, and a support base plate 16 is provided at the telescopic end of the vertical adjustment cylinder 15. The exhaust telescopic source 7 is fixed on the support base plate 16. That is, the vertical adjustment cylinder 15 drives the support base plate 16 and the exhaust telescopic source 7 to move up and down, so as to effectively avoid the paper cup group 2 that continues to move forward.

[0025] Furthermore, in order to ensure that the exhaust telescopic source 7 can extend and retract back and forth into the mouth of the paper cup, a positioning telescopic source 17 is provided on the support frame 6 located above the paper cup group 2. The telescopic end of the positioning telescopic source 17 is set towards the paper cup wall of the paper cup group 2, and a clamping plate 18 is provided on the telescopic end of the positioning telescopic source 17. A clamping space for clamping and fixing the paper cup group 2 is formed between the clamping plate 18 and the paper cup conveying platform 4.

[0026] In order to adjust the front-to-back position of the positioning telescopic source 17 relative to the paper cup assembly 2, so that the positioning telescopic source 17 can be applied to paper cup assemblies 2 composed of different stacked numbers of paper cups 2, the support frame 6 has a second assembly strip-shaped through hole 19 along the front-to-back direction. The positioning telescopic source 17 is fixed on the positioning adjustment seat, and the positioning adjustment seat can be slidably and relatively fixed on the second assembly strip-shaped through hole 19 by assembly screws. At the same time, in this embodiment, the first assembly strip-shaped through hole 8 and the second assembly strip-shaped through hole 19 are the same through hole structure.

[0027] Furthermore, considering the different cup opening positions of paper cups of different sizes, the positioning adjustment seat includes a second horizontal adjustment support plate 20, a second vertical adjustment support plate 21, and a second mounting plate 22. The second horizontal adjustment support plate 20 is connected to the second mounting strip-shaped through hole 19 by assembly screws. The second horizontal adjustment support plate 20 has a second horizontal strip-shaped through hole along the horizontal direction. The second vertical adjustment support plate 21 can slide and be relatively fixed on the second horizontal adjustment through hole by assembly screws. The second vertical adjustment support plate 21 has a second vertical strip-shaped through hole along the vertical direction. The second mounting plate 22 can slide and be relatively fixed on the second vertical strip-shaped through hole by assembly screws. The exhaust telescopic source 7 is connected to the second mounting plate 22.

[0028] In this embodiment, the exhaust telescopic source 7, the material pushing telescopic source 12, and the positioning telescopic source 17 all employ telescopic cylinders. Of course, the exhaust telescopic source 7, the material pushing telescopic source 12, and the positioning telescopic source 17 can also be commercially available electromagnets or hydraulic cylinders.

[0029] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
