Description

Technical Field

[0001] The utility model relates to a curling machine, in particular to a curling machine for the cup mouth of disposable plastic cups. Background Art

[0002] The opening edge of a plastic cup is relatively sharp and can easily cause scratches to the hand or mouth during use. Therefore, after the plastic cup is formed, it is necessary to process its opening edge to turn it outwards to form a smooth curled edge to prevent harm to the user's hand or mouth. The patent with the authorization announcement number

[0003] CN211307355U discloses a plastic curling machine, whose mechanism is relatively complex and inefficient, and many steps still require manual operation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a curling machine for the cup mouth of disposable plastic cups aiming at the existing technical status.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A curling machine for the cup mouth of disposable plastic cups includes a feeding structure, a curling structure and a stacking structure. The curling structure is arranged between the feeding structure and the stacking structure. The curling structure includes heating threaded rods and heating ceramic sheets. The heating threaded rods are arranged in a square pattern, and the heating ceramic sheets are arranged at intervals around the heating threaded rods.

[0007] Preferably, radial adjustment mechanisms are provided at both ends of the heating threaded rods.

[0008] Preferably, the radial adjustment mechanism includes a handle, a gear transmission group and a push rod. The handle is connected to the gear transmission group, the gear transmission group is connected to the push rod, and the push rod is arranged at both ends of the heating threaded rod.

[0009] The structure of the utility model is simple. By heating and transporting plastic cups with threaded rods at the same time, the working efficiency is greatly improved. The heating ceramic sheets arranged on the periphery also ensure the curling speed and effect. The radial adjustment mechanism can adjust the diameter to adapt to plastic cups of different specifications. Description of the Drawings

[0010] Figure 1 is the structural schematic diagram of the utility model.

[0011] Figure 2 is the internal structural schematic diagram of the curling structure.

[0012] Figure 3 is the structural schematic diagram of the heating threaded rod and the heating ceramic sheet.

[0013] Figure 4It is a schematic structural diagram of a radial adjustment mechanism.

[0014] In the figure, 1 is a feeding structure, 2 is a curling structure, 3 is a stacking structure, 4 is a heating screw rod, 5 is a heating ceramic sheet, 6 is a handle, 7 is a gear transmission group, and 8 is a push rod. Specific implementation mode

[0015] The following further details the present utility model with reference to the accompanying drawings.

[0016] Refer to Figures 1 to 4 As shown, a disposable plastic cup mouth curling machine includes a feeding structure 1, a curling structure 2 and a stacking structure 3. The curling structure 2 is arranged between the feeding structure 1 and the stacking structure 3. The curling structure 2 includes a heating screw rod 4 and a heating ceramic sheet 5. The heating screw rods 4 are arranged in a square pattern, and the heating ceramic sheets 5 are arranged at intervals around the heating screw rods. Radial adjustment mechanisms are provided at both ends of the heating screw rod 4. The radial adjustment mechanism includes a handle 6, a gear transmission group 7 and a push rod 8. The handle 6 is connected to the gear transmission group 7, the gear transmission group 7 is connected to the push rod 8, and the push rod 8 is arranged at both ends of the heating screw rod 4.

[0017] The motor drives the heating screw rod to rotate. The disposable plastic cup to be curled is transported through the feeding structure into the cavity formed by the heating screw rods. The mouth of the plastic cup is stuck in the thread of the heating screw rod. As the heating screw rod rotates, curling is completed within the curling structure and finally transported to the stacking structure. The heating temperature of the heating ceramic sheet is 200 - 250 °C, the heating temperature of the heating screw rod is 70 - 120 °C, and the distance between the heating screw rod and the heating ceramic sheet is 4 cm. If only the heating screw rod is used for curling, a higher temperature is required, which easily causes the plastic cup to deform. The present utility model combines the heating of the heating screw rod and the heating ceramic sheet to avoid this problem and has a better curling effect. When curling plastic cups with different diameters, adjust the radial adjustment mechanisms at both ends of the heating screw rod, rotate the handle, drive the gear transmission group and the push rod to move, and push the heating screw rod inward to reduce the diameters of the inlet and outlet.

[0018] The above content further details the present utility model in combination with specific preferred implementation modes. The technical scope of this utility model is not limited to the content in the specification. For those of ordinary skill in the art, improvements or transformations can be made according to the above description. All such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
