Description

Technical Field

[0001] The utility model relates to the technical field of disposable smooth cup production, in particular to a disposable smooth cup forming device. Background Art

[0002] A disposable smooth cup is a transparent, unpatterned plastic cup commonly used for beverages. Made of food-grade plastic, it is suitable for both cold and hot drinks and is odorless, heat-resistant, highly transparent, and pressure-resistant.

[0003] In the production of disposable smooth cups, plastic granules are placed in an extruder to form strips of plastic sheets, which are then placed in a punching machine and punched into the desired cups. After the cups are formed, most of the cups are still embedded in the molding grooves and need to be ejected using an ejection mechanism. However, the ejected cups will still remain on the mold and cannot be completely discharged. In addition, the ejected cups will be blocked by the plastic sheets that still need to be transported, which will affect the discharge and may cause damage to the cups or plastic sheets. Utility Model Content

A plurality of forming convex molds are installed at the bottom of the upper mold, and the forming convex molds correspond to the forming concave molds one by one.

[0008] Support rollers are provided at both ends above the lower mold. The ends of the support rollers are fixed to the base through connecting seats, and a cross-flow fan is provided on the support frame. The air outlet of the cross-flow fan corresponds to the lower mold, and the front projection of the cross-flow fan is located between the support rollers and the top surface of the lower mold.

After the mold is opened, the lower mold can be away from the plastic plate on the support roller, thereby avoiding the obstruction of the plastic plate to the cup discharge. The cup can be fully ejected by the ejection rod and blown out by the cross-flow fan, realizing a complete and effective discharge operation.

[0017] 2. The disposable smooth cup forming device uses an air pump to absorb the plastic plate attached to the forming punch when the mold is closed to ensure the cup is formed. When the mold is opened, air can be blown to blow the cup off the forming punch, allowing the cup to be completely separated from the forming punch, ensuring the cup's complete demoulding.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 4 A disposable smooth cup forming device includes a base 1, which is a hollow structure. A lower mold 2 is arranged above the base 1, and a first pushing mechanism 3 is installed at the bottom of the lower mold 2. The first pushing mechanism 3 is fixed in the base 1. In actual use, the first pushing mechanism 3 is one of a hydraulic cylinder, an electric push rod, and a cylinder, so that the lower mold 2 can be raised and lowered above the base 1.

[0025] Further, such as Figure 4 As shown, at least one first guide shaft 16 is vertically installed at the bottom edge of the lower mold 2. The bottom of the first guide shaft 16 slides through the top of the base 1 to provide guidance for the lifting and lowering of the lower mold 2, allowing the lower mold 2 to move stably.

[0026] A plurality of spaced-apart forming dies 4 are provided on the top of the lower mold 2. The forming dies 4 pass through the bottom of the lower mold 2. Each forming die 4 is provided with an ejector rod 5, which is vertically fixed to the top surface of the base 1. When the lower mold 2 rises, the ejector rod 5 can be separated from the forming die 4 without affecting the forming of the cup in the forming die 4. When the lower mold 2 is lowered, the cup in the forming die 4 can fall onto the ejector rod 5 and be ejected from the forming die 4, thereby realizing the discharge of the cup;

[0027] When in use, support rollers 18 are provided at both ends above the lower mold 2. The ends of the support rollers 18 are fixed to the base 1 through connecting seats 19. The strip-shaped plastic plate will be placed on the support rollers 18 at both ends for transmission. When the mold is closed, the lower mold 2 will be sent to the bottom of the plastic plate by the first pushing mechanism 3 and fit tightly against the plastic plate.

[0028] Subsequently, an upper mold 6 is provided above the lower mold 2, and a second pushing mechanism 7 is installed on the top of the upper mold 6. The second pushing mechanism 7 is fixed to the base 1 through a support frame 8, and multiple forming punches 9 are installed at the bottom of the upper mold 6. The forming punches 9 correspond one-to-one to the forming concave mold 4. In actual use, the second pushing mechanism 7 is one of a hydraulic cylinder, an electric push rod, and a pneumatic cylinder. The second pushing mechanism 7 will push the upper mold 6 downward and extend the forming punch 9 into the forming concave mold 4 to complete the stamping molding of the cup.

[0029] Furthermore, in order to ensure the stable lifting and lowering of the upper mold 6, a second guide shaft 12 is provided parallel to the side of the second pushing mechanism 7, the bottom of the second guide shaft 12 is fixed on the top of the upper mold 6, and the top of the second guide shaft 12 slides through the support frame 8.

[0030] It should be noted that if Figure 1 and Figure 4 As shown, the upper mold 6 is a hollow shell, and an air pump 11 is installed on the upper mold 6. One end of the air pump 11 is connected to the interior of the upper mold 6. Each forming punch 9 is a hollow shell connected to the upper mold 6, and a plurality of through holes 10 are opened on the forming punch 9. When the mold is closed, the air pump 11 will extract the air in the upper mold 6, so that the plastic plate fits into the forming punch 9, which is convenient for the molding of the cup. Then, when the mold is opened, the air pump 11 will supply air to the forming punch 9, so that the cup can fall off the forming punch 9 when the upper mold 6 is lifted, which is helpful for the discharge of the cup.

[0031] Specifically, after the lower mold 2 falls and the cup is ejected from the forming die 4, a cross-flow fan 13 is provided on the support frame 8. The air outlet of the cross-flow fan 13 corresponds to the lower mold 2, and the front projection of the cross-flow fan 13 is located between the support roller 18 and the top surface of the lower mold 2. The cross-flow fan 13 will blow air toward the top surface of the lower mold 2, thereby blowing the cup away from the lower mold 2 for quick discharge. The entire discharge process is away from the plastic plate placed on the support roller 18, so that the discharge of the cup will not be hindered by the plastic plate.

[0032] Furthermore, an exhaust hood 14 is installed on the air outlet of the cross-flow fan 13, and limit plates 15 are provided at both ends of the exhaust hood 14. The limit plates 15 are located at both ends of the lower mold 2 when viewed from the front, so that the air blown out by the cross-flow fan 13 is concentrated above the lower mold 2, ensuring that the cups can be fully discharged.

[0033] Finally, an inclined discharge chute 17 is provided on the side of the lower mold 2 away from the cross flow fan 13. The top of the discharge chute 17 corresponds to the lower mold 2, and the discharge chute 17 is fixed on the base 1. The blown cups will fall on the discharge chute 17 and fall along the discharge chute 17. In actual use, a collection device can be placed under the discharge chute 17 to collect the discharged cups.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
