Description

Technical field:

[0001] The utility model belongs to the technical field of packaging equipment, in particular to a disposable cup packaging machine. Background technology:

[0002] The paper cup packaging mechanism disclosed in the existing Chinese utility model patent (authorization announcement number CN212606392U) includes a sealing and cutting device, which has a horizontal knife for cutting the packaging film horizontally by heat sealing and a vertical knife for not cutting the packaging film longitudinally by heat sealing, the horizontal knife and the vertical knife are arranged in a T shape, the vertical knife is close to the front end of the horizontal knife, and the left and right film support plates are arranged above the sealing and cutting device, and the left and right film support plates are relatively opened and closed. That is, the stacked paper cups lie on the left and right film support plates, the packaging film is folded in a U shape and wrapped around the outer periphery of the left and right film support plates, and at this time, the lower side of the packaging film is closed under the heat sealing action of the horizontal knife, and the packaging process is as follows: the packaging film moves downward, and under the opening and closing action of the left and right film support plates, the stacked paper cups fall into the packaging film, and the packaging heat sealing of the stacked paper cups is achieved through the heat sealing cutting of the horizontal knife and the heat sealing action of the vertical knife.

[0003] Since the packaging film is in a state of being stretched open by the left and right film supporting plates, the horizontal knife will squeeze the two side walls of the packaging film inward during operation, causing the packaging film to produce an upward displacement variable, resulting in the position of the two side edges of the opening of the packaging film being misaligned. Ultimately, under the heat sealing of the horizontal and vertical knives, the side edges of the packaging mold will be wrinkled and cannot be effectively sealed. Summary of the invention:

[0004] The utility model aims to provide a disposable cup packaging machine, which clamps and fixes the corresponding side edges of the packaging film in advance with the aid of auxiliary clamping components before heat sealing with horizontal and vertical knives, thereby ensuring that the side edges of the packaging film can be effectively sealed and the seal is neat and wrinkle-free.

[0005] The utility model is achieved in this way:

[0006] A disposable cup packaging machine comprises a frame, on which are arranged left and right film-supporting assemblies capable of relatively opening and closing, and a sealing and cutting device located below the left and right film-supporting assemblies, the sealing and cutting device comprising a horizontal knife capable of transversely heat-sealing and cutting the packaging film, and a vertical knife capable of longitudinally heat-sealing the packaging film, an auxiliary clamping assembly being arranged on the frame at a side of the vertical knife away from the horizontal knife, the auxiliary clamping assembly being capable of clamping and placing the corresponding side edges of the packaging film.

[0007] In the above-mentioned disposable cup packaging machine, the auxiliary clamping assembly includes a thumb cylinder and a power air pump that provides air energy to the thumb cylinder. The thumb cylinder is fixed to the frame through a connecting bracket, and the two clamping ends of the thumb cylinder are used to clamp the packaging film.

[0008] In the above-mentioned disposable cup packaging machine, clamping rubber pads are arranged on the opposite side walls of the two clamping ends of the thumb cylinder.

[0009] In the above-mentioned disposable cup packaging machine, the two clamping ends of the thumb cylinder are arranged vertically upward, and the bottom edge of the packaging film is inserted downward between the two clamping ends of the thumb cylinder.

[0010] In the above-mentioned disposable cup packaging machine, the connecting bracket is vertically slidably connected to the frame, and the relative position between the connecting bracket and the frame is fixed by a fastening bolt.

[0011] The prominent advantages of the present utility model compared with the prior art are:

[0012] The structure of the present utility model is simple, reasonably designed and low in cost. Before the transverse knife and the vertical knife are heat-sealed, the corresponding side edges of the packaging film are clamped and fixed in advance by means of the auxiliary clamping assembly, so as to ensure that the side edges of the packaging film can be effectively sealed, and the seal is neat and free of wrinkles. Description of the drawings:

[0013] Figure 1 It is a structural diagram of the auxiliary clamping assembly of the present utility model cooperating with the sealing and cutting device.

[0014] In the figure: 1, left and right film supporting assemblies; 2, packaging film; 3, transverse knife; 4, vertical knife; 5, thumb cylinder; 6, connecting bracket; 7, clamping rubber pad. Specific embodiments:

[0015] The following further describes the present utility model with specific embodiments, see Figure 1 :

[0016] A disposable cup packaging machine includes a frame, on which there are left and right film supporting assemblies 1 that can perform relative opening and closing actions, and a sealing and cutting device located below the left and right film supporting assemblies 1. The sealing and cutting device includes a transverse knife 3 that can perform transverse heat-sealing and cutting on the packaging film 2, and a vertical knife 4 that can perform longitudinal heat-sealing on the packaging film 2. An auxiliary clamping assembly is arranged on the frame on the side of the vertical knife 4 away from the transverse knife 3, and the auxiliary clamping assembly can clamp and release the corresponding side edges of the packaging film 2.

[0017] The structure of the present utility model is simple, reasonably designed and low in cost. Before the transverse knife 3 and the vertical knife 4 are heat-sealed, the corresponding side edges of the packaging film 2 are clamped and fixed in advance by means of the auxiliary clamping assembly, so as to ensure that the side edges of the packaging film 2 can be effectively sealed, and the seal is neat and free of wrinkles.

[0018] Among them, the auxiliary clamping assembly can adopt two relatively arranged strip-shaped clamping plates to be able to clamp a large area of the corresponding side edge of the packaging film 2. In this embodiment, the auxiliary clamping assembly includes a thumb cylinder 5 and a power air pump that provides air energy for the thumb cylinder 5. The thumb cylinder 5 is fixed to the frame through a connecting bracket 6, and the two clamping ends of the thumb cylinder 5 are used to clamp the packaging film 2. That is, the two clamping ends of the thumb cylinder 5 are used to fix the position of the corresponding side edge of the packaging film 2. When the cross knife 3 performs heat sealing operation, the packaging film 2 moves upward, so that the side edge of the packaging film 2 is straightened, and effective sealing of the corresponding side of the packaging film 2 is achieved.

[0019] Furthermore, in order to ensure stable clamping of the packaging film 2, clamping rubber pads 7 are arranged on the opposite side walls of the two clamping ends of the thumb cylinder 5.

[0020] And, in this embodiment, the two clamping ends of the thumb cylinder 5 are arranged vertically upward, and the bottom edge of the packaging film 2 is inserted downward between the two clamping ends of the thumb cylinder 5. That is, the thumb cylinder 5 fixes the position of the bottom end of the corresponding side of the packaging film 2, so that the entire corresponding side of the packaging film 2 can be straightened under the action of the cross knife 3.

[0021] In addition, the connecting bracket 6 is vertically slidably connected to the frame, and the relative position of the connecting bracket 6 and the frame is fixed through a fastening bolt. That is, one or more vertical strip-shaped holes can be provided on the connecting bracket 6, and the fastening bolt is penetrated and matched in the vertical strip-shaped holes.

[0022] The above embodiments are only one of the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the shape, structure, and principle of the present invention should be covered within the protection scope of the present invention.
