Description

Technical Field

[0001] The utility model belongs to the field of packaging devices, and in particular relates to an automatic cup packaging device. Background Art

[0002] Currently, in the production process of beverage cups, it is usually necessary to stack multiple cups to a certain number and then use plastic film to package the multiple cups.

[0003] However, in the actual production process, the above packaging process is generally completed manually, which is not only prone to damage of the plastic film due to operational errors, thereby affecting the packaging quality, but also the manual operation is cumbersome (needing to take cup material, take film material, pack, and seal), time-consuming, inefficient, and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a new automatic cup packaging device.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An automatic cup packaging device, comprising:

[0007] A cup material supply unit, which is used to supply a plurality of cup bodies stacked in sequence in the front-to-back direction;

[0008] a film material supply unit comprising an unwinding roller having a plastic film roll, wherein the plastic film is unwound and forms a packaging section that is transported from front to back;

[0009] The packaging unit includes a packaging channel arranged on the packaging section transmission path and matching the multiple cup bodies, and a sealing component with a sealing area located behind the packaging channel. When the multiple cup bodies enter the packaging channel, as the packaging section enters the packaging channel and is transmitted from front to back, the packaging channel drives the packaging section to gradually converge from the two side edges to cover the surfaces of the multiple cup bodies and form an opening. The multiple cup bodies move synchronously from front to back, and the opening passes through the sealing area to form a seal.

[0010] Preferably, when the packaging section enters the packaging channel, the packaging section fits in with the inner wall of the packaging channel, thereby ensuring that the plastic film evenly covers the cup body, thereby ensuring that the subsequent process can be smoothly sealed.

[0011] According to a specific embodiment and preferred aspect of the present invention, the packaging channel includes a bottom plate and two side plates vertically disposed on opposite sides of the bottom plate. As the plastic film is transported from front to back, the packaging section gradually conforms to the inner walls of the bottom plate and the two side plates. When the packaging section is wrapped around the surfaces of multiple cups, the edges of the packaging section form an opening above the multiple cups, thereby facilitating the sealing operation.

[0012] Preferably, the top of each side panel forms a guide edge extending upward and downward at an angle. The packaging channel also includes a guide rod disposed at the front end of the base panel. The guide rod comprises a first rod extending along the width of the packaging section and flush with the base panel, and two second rods extending backward and outward from each end of the first rod. The middle portion of the packaging section passes around the first rod and then travels along the base panel. The sides of the packaging section then pass around the corresponding second rod and guide edge, then travel along the inner walls of the side panels. The provision of the first and second rods facilitates the gradual bending of the plastic film during transportation, forming three sections that are transported along the base panel and the two side panels, reducing the likelihood of the plastic film breaking and ensuring stable transportation.

[0013] Specifically, the centerline of the first rod coincides with the centerline of the packaging section; and / or the guide edges on both sides are flush. This ensures that the widths of the two sides of the packaging section are consistent, ensuring the positional accuracy of the opening formed, thereby ensuring accurate sealing in subsequent operations.

[0014] According to another specific implementation and preferred aspect of the present invention, the sealing component includes two sealing wheels spaced apart along the width direction of the packaging section, wherein a sealing area is formed between the two sealing wheels, and the opening entering the sealing area is sealed under the squeeze of the two sealing wheels. The sealing wheels can be heated synchronously to improve the sealing efficiency and ensure the sealing quality. It should be noted that when the first batch of cup bodies is packaged, manual operation is required to make the opening enter the sealing area. Therefore, when the subsequent batches of cup bodies are packaged, the corresponding opening can automatically and gradually close into the sealing area to form a seal as they are transported.

[0015] According to another specific embodiment and preferred aspect of the present invention, the cup material supply unit includes a conveyor belt connected to the front end of the packaging channel, and multiple cup bodies are placed on the conveyor belt and transported from front to back, thereby achieving continuous and stable feeding of the cup bodies.

[0016] Preferably, a gap is formed between the conveyor belt and the front end of the packaging channel, and the unwinding roller is arranged below the packaging unit, and the plastic film passes through the gap from bottom to top and then is transferred backward to form a packaging section. In this way, the layout is compact and space-saving.

[0017] Preferably, the film material supply unit further comprises a tension roller group for adjusting the surface tension of the plastic film, a reversing roller group for driving the plastic film to be transported toward the packaging channel, and a traction roller group for traction of the plastic film.

[0018] The film supply unit also includes a shaping roller assembly, consisting of a first shaping roller and a second shaping roller spaced apart in the thickness direction of the plastic film. A shaping channel, aligned with the film, is formed between the first and second shaping rollers. The film then passes through the shaping channel and enters the packaging channel, ensuring a smooth surface to prevent wrinkles during packaging.

[0019] Due to the implementation of the above technical solution, the utility model has the following advantages compared with the prior art:

[0020] The prior art generally completes the cup packaging process manually, which is not only prone to damage of the plastic film due to operational errors, thus affecting the packaging quality, but also the manual operation is cumbersome (needing to take cup material, take film material, pack, and seal), time-consuming, inefficient, and labor-intensive; the present application makes an overall design of the structure of the automatic cup packaging device, cleverly solving the deficiencies and defects of the prior art. After adopting the packaging device, a plurality of cups stacked in sequence in the front and back directions are supplied by the cup material supply unit; the plastic film is supplied by the film material supply unit, wherein the plastic film is unwound from the unwinding roller and forms a packaging section that is transmitted from front to back. When packaging, a plurality of cups enter the packaging channel on the transmission path of the packaging section. As the packaging section enters the packaging channel, The packaging channel is used for packaging and is transmitted from front to back, and the packaging section gradually converges toward each other from the edges on both sides and covers the surfaces of multiple cup bodies to form an opening, thereby driving the multiple cup bodies to be transported from front to back, and when passing through the sealing area, the opening is sealed by the sealing component; therefore, compared with the prior art, the utility model is based on the continuous feeding of plastic film and multiple cup bodies on the one hand, and the packaging section is gradually converged and covered on the surface of the cup body through the packaging channel, and the cup body is driven to move synchronously under the front and back transmission of the plastic film to automatically form a seal through the sealing component, which greatly reduces the damage rate of the plastic film caused by human errors and effectively improves the packaging quality; on the other hand, it realizes continuous automatic feeding, packaging and sealing, which is simple and convenient to operate, has high packaging efficiency and low labor intensity.

[0036] like Figures 1 to 6 As shown, the automatic cup packaging device of this embodiment includes a cup material supply unit 1, a film material supply unit 2, and a packaging unit 3.

[0037] Specifically, the cup material supply unit 1 includes a conveyor belt 10 extending horizontally front to back, and multiple cup bodies B stacked in sequence in the front to back direction are placed on the conveyor belt 10 and transported from front to back along the conveyor belt, wherein the rear end of the conveyor belt 10 is connected to the packaging unit 3.

[0038] In this example, the film material supply unit 2 is arranged below the packaging unit 3, and includes an unwinding roller 20, a tension roller group 21, a reversing roller group 22, and a traction roller group (not shown in the figure, but it is not difficult to imagine).

[0039] In some specific embodiments, the plastic film roll is mounted on the unwinding roller 20, and the rear end of the plastic film M is pulled by the traction roller group to implement unwinding, and as the plastic film M is unwound from the unwinding roller 20, the plastic film M passes through the tension roller group 21 and the reversing roller group 22 respectively, wherein the tension roller group 21 adjusts the surface tension of the plastic film M, and the reversing roller group 22 drives the plastic film M to adjust the transmission direction so as to be transmitted toward the packaging unit 3, wherein the tension roller group 21, the reversing roller group 22, and the traction roller group are all conventional technologies and will not be elaborated here.

[0040] For ease of implementation, a gap is formed between the conveyor belt 10 and the packaging unit 3. The plastic film M passes through the gap from bottom to top and is then transported horizontally backward to form the packaging section M0. The film supply unit 2 also includes a shaping roller assembly 23, which includes a first shaping roller 231 and a second shaping roller 232 spaced apart in the thickness direction of the plastic film. A shaping channel t is formed between the first shaping roller 231 and the second shaping roller 232, which matches the plastic film M. After passing through the shaping channel t, the plastic film M enters the packaging unit 3. This ensures a smooth surface on the plastic film to prevent wrinkles during packaging.

[0041] In this example, the packaging unit 3 includes a packaging channel 30 arranged on the transmission path of the packaging section M0 and matching multiple cup bodies B, and a sealing component 31 with a sealing area q located behind the packaging channel 30, wherein the front end of the packaging channel 30 is connected with the conveyor belt 10 and is arranged flush. When multiple cup bodies B enter the packaging channel 30, as the packaging section M0 enters the packaging channel 30 and is transmitted from front to back, the packaging channel 30 drives the packaging section M0 to gradually converge from the two side edges to cover the surfaces of the multiple cup bodies B and form an opening k. The multiple cup bodies B move synchronously from front to back, and the opening k passes through the sealing area q to form a seal.

[0042] In order to further facilitate implementation, when the packaging section M0 enters the packaging channel 30, the packaging section M0 is in contact with the inner wall of the packaging channel 30. Here, it is ensured that the plastic film covers the cup body evenly, thereby ensuring that the subsequent process can be smoothly sealed.

[0043] In some embodiments, the packaging channel 30 includes a bottom plate 300 and two side plates 301 vertically disposed on opposite sides of the bottom plate 300. As the plastic film M is transported from front to back, the packaging section M0 gradually conforms to the inner walls of the bottom plate 300 and the two side plates 301. When the packaging section M0 is wrapped around the surfaces of the multiple cups B, the edges of the packaging section M0 form an opening above the multiple cups B, facilitating the sealing operation.

[0044] At the same time, a guide edge b extending upward and downward is formed at the top of each side panel 301. The packaging channel 30 also includes a guide rod 302 disposed at the front end of the base panel 300. The guide rod 302 comprises a first rod g1 extending along the width of the packaging section M0 and aligned with the base panel 300, and two second rods g2 extending backward and outward from each end of the first rod g1. The middle portion of the packaging section M0 passes around the first rod g1 and then travels along the base panel 300. The two sides of the packaging section M0 then pass around the corresponding second rod g2 and guide edge b, then travel along the inner wall of the side panel 301. The provision of the first and second rods facilitates the gradual bending of the plastic film during transportation, forming three sections that are transported along the base panel and the two side panels, reducing the possibility of plastic film breakage and ensuring stable transportation.

[0045] To further facilitate implementation, the centerline of the first rod g1 coincides with the centerline of the packaging section M0, and the guide edges b on both sides are flush. This ensures that the width of the two sides of the packaging section is consistent, ensuring the positional accuracy of the formed opening and ensuring accurate sealing in subsequent operations.

[0046] In this example, the sealing component 31 includes two sealing wheels 310 spaced apart along the width of the packaging section. A sealing area q is formed between the two sealing wheels 310, and the openings entering the sealing area q are squeezed by the two sealing wheels 310 to form a seal. The sealing wheels can be heated synchronously to improve sealing efficiency and ensure sealing quality. It should be noted that when packaging the first batch of cups, manual operation is required to allow the openings to enter the sealing area. Therefore, when packaging subsequent batches of cups, the corresponding openings can automatically and gradually close into the sealing area to form a seal as they are transported.

[0047] In summary, after adopting the packaging device, multiple cup bodies stacked in sequence in the front-to-back direction are supplied by the cup material supply unit; the plastic film is supplied by the film material supply unit, wherein the plastic film is unwound from the unwinding roller and forms a packaging section that is transmitted from front to back. When packaging, multiple cup bodies enter the packaging channel on the transmission path of the packaging section. As the packaging section enters the packaging channel and is transmitted from front to back, the packaging section gradually gathers toward each other from the edges on both sides and covers the surfaces of the multiple cup bodies to form an opening, thereby driving the multiple cup bodies to be transmitted from front to back, and when passing through the sealing area, the opening is sealed by the sealing component; therefore, compared with the prior art, the utility model is based on the continuous feeding of plastic film and multiple cup bodies on the one hand, and the packaging section is gradually gathered and covered on the surface of the cup body through the packaging channel. On the one hand, the cup body is driven to move synchronously with the front and rear transmission of the plastic film to automatically form a seal through the sealing component, which greatly reduces the damage rate of the plastic film caused by human error and effectively improves the packaging quality; on the other hand, it realizes continuous automatic feeding, packaging and sealing, which is simple and convenient to operate, has high packaging efficiency and low labor intensity; on the other hand, it ensures that the plastic film covers the cup body evenly, so as to ensure that the subsequent sealing can be done smoothly; on the other hand, by setting the first rod body and the second rod body, the plastic film is gradually bent during transmission and formed into three parts to correspond to the transmission along the bottom plate and the two side plates, reducing the probability of plastic film breakage and ensuring stable transmission of the plastic film; on the fifth hand, the width of the two sides of the packaging section is consistent, ensuring the position accuracy of the opening formed, so as to ensure accurate sealing in the subsequent sequence;

[0048] The above detailed description of the utility model is intended to enable people familiar with the technology in this field to understand the content of the utility model and implement it. It is not intended to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
