[0002] The plastic cup processing thermoforming device is mainly used to heat and soften plastic sheets and then press them into plastic cups of required shapes through molds. The plastic sheets are fed into the heating area through an automatic feeding device and heated to the softening temperature by heating elements. The softened plastic sheets are fed into the forming mechanism. The upper mold table and the lower mold table are closed under the drive of a servo motor to press the plastic sheets into the shape of a cup. The formed plastic cups are separated from the molds through the mold opening action and further processed by subsequent processes. The plastic cup processing thermoforming device has broad application prospects in industries such as food, beverage, and daily chemicals.

[0003] In the patent with the application number 202322710011.6, a plastic cup processing thermoforming device is disclosed. This application is provided with a blanking device. When the lower mold moves upward for production, cooling can be carried out through the first air guide cover at this time. When the lower mold moves downward, the plastic cup can be ejected from the mold hole through a push rod, and the plastic cup can be blown out through the air in the first air guide cover to complete blanking. In the use process of the existing heating and forming device, the mold needs to be installed on an injection molding device for injection molding. When the mold is being installed and transported, or when it is placed after use, dust and the like are likely to enter the cavity through the gaps of the mold table. If a large amount of dust enters, cleaning is required before injection molding, which affects the convenience and practicality in the use process of the device. For this reason, we propose a plastic cup processing thermoforming device. Content of the Utility Model

Detailed Description of the Embodiment

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1

[0020] Please refer to Figure 1 , Figure 2 and Figure 3, the present utility model provides a technical solution: Plastic cup thermoforming is a process of processing thermoplastic sheet materials into various plastic products, which is suitable for manufacturing products with thin walls and large surface areas, such as disposable plastics. The thermoforming process is based on the physical properties of plastics, that is, plastics will soften when heated and harden when cooled. By controlling the heating and cooling processes, the shape and size of plastics can be precisely controlled, thus realizing the manufacture of the required products. A plastic cup processing thermoforming device includes an upper die base 100 and a lower die base 104. An upper push plate base 101 is installed at the top of the upper die base 100, and an upper die table 102 is installed at the bottom of the upper die base 100. A lower die table 105 is installed at the top of the lower die base 104, and a lower push plate base 106 is installed at the bottom of the lower die base 104. Guide posts 103 are installed between the upper die base 100 and the lower die base 104. A lifting sealing convex ring 201 is provided at the bottom edge of the upper die table 102, and a lifting sealing sleeve seat 200 is installed at the top edge of the lower die table 105. A lifting sealing groove 207 is opened at the top of the lifting sealing sleeve seat 200. Threaded lifting seats 202 are provided on both sides of the lifting sealing sleeve seat 200. Lifting adjustment seats 205 are fixedly installed on both sides of the lower die table 105. Lifting screw rods 206 are installed on the lifting adjustment seats 205. Rotating sleeve seats 204 are provided on the lifting screw rods 206. Hexagonal screw heads 203 are provided at the bottoms of the lifting screw rods 206. If the device in this application is used for thermoforming and processing plastic cups, when the device is being transported or after use and being transported, after the upper die table 102 and the lower die table 105 are combined together, the lifting screw rod 206 can be rotated and adjusted to make the lifting sealing sleeve seat 200 and the lifting sealing convex ring 201 contact and seal with each other. Turning the lifting screw rod 206 requires using a tool to engage with the hexagonal screw head 203. By turning the lifting screw rod 206 with a tool, when the lifting screw rod 206 rotates, it rotates on the lifting adjustment seat 205 through the rotating sleeve seat 204. At the same time, one end of the lifting screw rod 206 drives the threaded lifting seat 202 to lift through the thread. The lifting of the threaded lifting seat 202 drives the lifting sealing sleeve seat 200 to lift synchronously, so that the lifting sealing groove 207 at the top of the lifting sealing sleeve seat 200 contacts and seals with the lifting sealing convex ring 201 at the edge of the upper die table 102. Through the raised lifting sealing sleeve seat 200, dust can be prevented from entering the interior of the device from the gap between the upper die table 102 and the lower die table 105, thus avoiding cleaning the device before use and improving the practicability of the device.

[0021] Specifically, the lifting screw rod 206 is rotatably installed on the lifting adjustment seat 205 through the rotating sleeve seat 204, and the other end of the lifting screw rod 206 is screwed through the threaded lifting seat 202. The lifting of the lifting sealing sleeve seat 200 is driven by the rotation of the lifting screw rod 206. At the same time, the upper die table 102 and the lower die table 105 are aligned through the lifting sealing groove 207 and the lifting sealing convex ring 201, which not only ensures the stable lifting of the structure but also improves the practicability of the device.

[0022] Example 2

[0023] Please refer to Figure 1 、 Figure 2 and Figure 3 , the present utility model provides a technical solution: a hot forming device for plastic cup processing. At both inner ends of the lifting and sealing sleeve seat 200, lifting limit grooves 300 are provided. At the top of both sides of the lower die table 105, integral lifting limit blocks 301 are arranged. Between the lifting and sealing sleeve seat 200 and the lower die table 105, the lifting and limiting are carried out through the lifting limit grooves 300 and the lifting limit blocks 301. When the lifting and sealing sleeve seat 200 is adjusted in lifting, the lifting limit block 301 and the positioning bolt 302 can also play a limiting role on the lifting and sealing sleeve seat 200, avoiding the shaking and instability of the lifting and sealing sleeve seat 200, thereby improving the practicability and stability of the device. Specifically, a positioning bolt 302 is arranged on one side of the lifting and sealing sleeve seat 200 where the lifting and sealing groove 207 is located. When the lifting and sealing sleeve seat 200 contacts the lifting and sealing convex ring 201, it can also be locked by the positioning bolt 302. After the lifting and sealing groove 207 on the lifting and sealing sleeve seat 200 contacts and presses the lifting and sealing convex ring 201, the positioning bolt 302 can be locked. The lifting and sealing sleeve seat 200 and the lifting and sealing convex ring 201 are fixed by the positioning bolt 302, and at the same time, it is also the fixation of the upper die table 102 and the lower die table 105, avoiding the dislocation of the upper die table 102 and the lower die table 105 caused by bumps during the movement of the device, thereby improving the stability of the device.

[0024] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
