Description

Technical Field

[0001] The utility model relates to the technical field of necking processing, in particular to a cup mouth forming device for a thermos cup. Background Technique

[0002] A thermos cup is a water container for keeping hot water warm. During the processing of a thermos cup made of metal material, necking processing is required. By necking the cup mouth, it can be ensured that the cup lid can fit tightly and be closed, avoiding the overflow of hot liquid or beverage. After the necking treatment of the cup mouth, the appearance is more neat and unified, meeting the aesthetic requirements and improving the appearance quality of the product.

[0003] The Chinese patent discloses a necking device for a thermos cup (authorization publication number CN218310471U). The patented technology includes a machine tool, on which a control console is fixedly connected, and a fixed rod is fixedly connected to the machine tool. There are two fixed rods and they are symmetrically distributed. The top end of the fixed rod is fixedly connected with a fixing plate. A sliding plate is slidably connected to the fixed rod. The top surface of the sliding plate is fixedly connected with a connecting rod, and the top end of the connecting rod is connected to the machine tool. The bottom side of the sliding plate is rotatably connected with a pressing block through a bearing. A rotating seat is rotatably connected to the machine tool, and a bearing block is fixedly connected to the inside of the rotating seat. A stop block is fixedly connected to the machine tool, and the top end of the stop block is at the same horizontal position as the top end of the bearing block; during use, the inner tube of the thermos cup is rotated at a high speed and deformed by extrusion. The operation process is simple, and the situation of the cup mouth wrinkling will not occur during the operation process.

[0004] This patented technology avoids the wrinkling of the cup mouth during the necking processing of the thermos cup, but there are still deficiencies in the use process. It can only process one specification of the thermos tube for necking. When the specifications of the thermos cup and the necking change, the equipment needs to be replaced, increasing the production cost, and the adaptability of the processing equipment is low. Therefore, those skilled in the art provide a cup mouth forming device for a thermos cup to solve the problems raised in the above background technique. Content of the Utility Model

[0042] Embodiment 1

[0043] Please refer to Figures 1 - 5 As shown, this embodiment is a cup mouth forming device for a thermos cup, including a mounting frame 100.

[0044] The necking forming structure 200 includes a hydraulic rod 1 (207), a lifting plate (208) located at the lower end of the hydraulic rod 1, a base plate (205) located below the lifting plate, a gear ring (203) located on the outer wall of the base plate, forming blocks (209) distributed in an annular array below the base plate, pressing die balls (210) rotatably installed inside the forming blocks, a motor (201) located at one side of the lower end of the base plate, and a gear (202) located at the lower end output of the motor and meshing with the gear ring.

[0045] Installation holes are provided inside the four corners of the mounting bracket 100;

[0046] A rotating ring 204 is provided at the upper end of the bottom plate 205, and an annular slide rail 206 is provided at the upper end of the bottom plate 205. The rotating ring 204 is rotatably mounted inside the slide rail 206;

[0047] Use the necking forming structure 200;

[0048] It is necessary to cooperate with a fixture to clamp and fix the thermos cup directly below the vertical position corresponding to the center of the bottom plate 205. The motor 201 drives the gear 202 to rotate, pushes the toothed ring 203. Through the rotation of the rotating ring 204 inside the slide rail 206, the bottom plate 205 is rotationally supported. The bottom plate 205 drives the forming block 209 to rotate. The hydraulic rod 207 drives the forming block 209 to descend, contacts the cup mouth of the thermos cup through the pressing die ball 210, and during the continuous descent process, squeezes the cup mouth of the thermos cup inward to perform necking processing on the cup mouth of the thermos cup. The necking specification of the cup mouth of the thermos cup gradually decreases. When the outer wall of the cup mouth of the thermos cup deforms due to rotational extrusion, relatively fine control can be achieved, thus better meeting the quality requirements of processing.

[0049] Embodiment 2

[0050] Please refer to Figures 1 - 5 As shown, this embodiment further includes on the basis of Embodiment 1;

[0051] And;

[0052] An adjusting structure 300, including a hydraulic rod 307, a lifting frame 308 at the lower end of the hydraulic rod 307, an adjusting ring 310 sleeved outside the forming block 209, guide rails 301 annularly arranged at the lower end of the bottom plate 205, a support ring 302 on one side at the lower end of the guide rail 301, and a spring 303 fixed between the support ring 302 and the forming block 209.

[0053] The inner wall of the adjusting ring 310 is rotatably sleeved with annularly arranged die-adjusting balls 311;

[0054] The outer wall of the adjusting ring 310 is provided with a connecting rod 309 sleeved outside the bottom plate 205 and connected to the lifting frame 308 at the upper end;

[0055] The upper end of the forming block 209 is provided with a slider 304 slidably mounted on the outer wall of the guide rail 301;

[0056] A guide sleeve 306 is embedded and installed inside the forming block 209, a guide rod 305 is slidably inserted inside the guide sleeve 306, and one end of the guide rod 305 is connected to the support ring 302;

[0057] Use the adjusting structure 300;

[0058] Through the elastic support of the spring 303, when the adjusting ring 310 is adjusted, it drives the forming block 209 to move through its own elasticity, realizing the adjustment of the radius of the forming block 209. The adjusting die ball 311 contacts the outer wall of the forming block 209. When the requirement for necking processing of the mouth of the thermos cup changes, the forming block 209 is adjusted through the adjusting structure 300 to adapt to the necking processing of thermos cup mouths of different specifications. During the use process, the forming blocks 209 distributed in an annular array are elastically supported by the spring 303 and the extrusion radius of the adjusting ring 310, ensuring the stable operation of the equipment during the processing, reducing the variation and waste in product processing. At the same time, the flexible adjustment of the necking size and shape of the thermos cup meets the necking processing requirements of different thermos cup mouths.
