Description

Technical Field

[0001] This utility model relates to the field of paper cup production technology, and in particular to a cup body forming device for paper cup production. Background Technology

[0002] Paper cup forming equipment is a crucial piece of equipment in the food packaging machinery industry, primarily used to process paper cup raw materials into standard cup bodies through forming processes. With increasing environmental protection requirements and growing demand for disposable paper cups, the market is placing higher demands on the forming efficiency, product adaptability, and automation level of paper cup production equipment. Traditional cup forming processes often suffer from inconvenient adjustments and poor adaptability, necessitating the development of a new forming device capable of quickly adapting to the production of paper cups of different specifications.

[0003] Existing paper cup forming technology mainly employs fixed molds combined with hydraulic forming. A typical device includes a frame, clamping rollers, forming molds, and a drive mechanism. Its working principle involves driving the clamping rollers to clamp and form the cup body material. However, the clamping rollers are usually designed with fixed dimensions, and different specifications of products are produced by replacing the entire set of clamping rollers. However, existing technology has a significant drawback: due to the fixed-size clamping roller structure, switching to paper cups of different diameters requires stopping the machine to replace the entire set of clamping rollers, leading to low production efficiency and increased equipment setup time. Therefore, a cup body forming device for paper cup production is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cup body forming device for paper cup production, which aims to improve the problem that the forming structure size used in the prior art cannot automatically adapt to different cup sizes, thus reducing the practicality of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cup body forming device for paper cup production, comprising a support frame, wherein the support frame has left and right symmetrical arc grooves inside, a mounting column is fixedly connected to the center of one side of the support frame, a mold is provided on the opposite side of the mounting column, and left and right symmetrical forming components are slidably connected inside the support frame;

[0006] The two molding components include a limiting frame, the outer wall of which is slidably connected to the inner wall of the arc-shaped groove. A limiting rod is slidably connected inside the limiting frame. A limiting block is fixedly connected to one end of the limiting rod. A hinge block is rotatably connected to one side of the inner wall of the limiting rod. A connecting frame is fixedly connected to one side of the outer wall of the hinge block. A rotating roller is rotatably connected inside the connecting frame. A spring is sleeved on the outer wall of the limiting rod. A driving component is installed on the other side of the outer wall of the support frame.

[0007] Furthermore, the drive assembly includes a motor, one side of which is fixedly connected to the other side of the outer wall of the support frame. A spur gear is fixedly connected to the output end of the motor. A symmetrical half gear is rotatably connected to the outer wall of the support frame near the spur gear. A sliding plate is fixedly connected to the outer wall of the two half gears. One half gear meshes with the spur gear. The sliding plate is slidably connected to the limiting frame.

[0008] Furthermore, an electric slide rail is fixedly connected to the upper surface of the support frame, and a feeding rack is slidably connected to the outer wall of the electric slide rail.

[0009] Furthermore, an L-shaped bracket is fixedly connected to one side of the upper surface of the unloading rack, and a limit rod is slidably connected inside the L-shaped bracket.

[0010] Furthermore, a spring is sleeved on the outer wall of the second limiting rod, and a roller is installed at one end of the second limiting rod.

[0011] Furthermore, multiple fixing blocks are fixedly connected to the outer wall of the mounting column, and a plug rod is fixedly connected to one side of each fixing block. Symmetrical locking blocks are slidably connected inside the plug rod, and a spring is provided between two locking blocks.

[0012] Furthermore, a telescopic rod is fixedly connected to one side of another fixed block, and a material ejection block is fixedly connected to one end of the telescopic rod. A spring is sleeved on the outer wall of the telescopic rod.

[0013] Furthermore, a mounting bracket is fixedly connected to one side of the outer wall of the mold, the inner wall of the mounting bracket is slidably connected to the outer wall of the mounting column, and the mounting bracket is slidably connected to the insertion rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the driving component drives the limiting frame to slide within the arc-shaped groove, thereby causing the paper cup material to adhere to the outer wall of the mold. The movement of the limiting frame causes the connecting frame to press against the material and lift it up in the mold for forming. At the same time, the rotating roller is forced to slide the limiting rod on one side of the connecting frame inside the limiting frame. The cooperation between the limiting rod and the spring achieves efficient paper cup forming while adapting to paper cups of different diameters, thus improving the practicality of the device.

[0016] 2. In this utility model, the feeding rack is moved to the opening of the paper cup by the electric slide rail, and the rollers abut against the opening of the paper cup. Then the feeding rack moves in the opposite direction, which makes it easy to quickly feed the paper cup. At the same time, by pressing the locking block, the second spring is contracted, and the reaction force of the third spring pushes the mounting frame, which makes it easy to change the mold of different sizes, thus improving the practicality of the device.

[0028] Reference Figure 1 , Figure 4 and Figure 5An electric slide rail 15 is fixedly connected to the upper surface of the support frame 1. The electric slide rail 15 is used to provide a precise linear motion trajectory. A feeding rack 16 is slidably connected to the outer wall of the electric slide rail 15. The feeding rack 16 is used to complete the feeding operation of paper cups. An L-shaped bracket 17 is fixedly connected to one side of the upper surface of the feeding rack 16. The L-shaped bracket 17 is used to support the limiting mechanism. A second limiting rod 18 is slidably connected inside the L-shaped bracket 17.

A telescopic rod 25 and an ejector block 26, in conjunction with a spring 27, enable quick disassembly of the mold 14. A mounting bracket 28 ensures precise positioning of the mold 14.

[0030] Working principle: When the paper cup forming device is needed, first, the rotating roller 12 is reset above the feeding rack 16. The paper cup material is placed between the rotating roller 12 and the mold 14. At this time, the starting motor 3 drives the spur gear 4 to mesh with one half gear 5 and rotate. Then, after the two half gears 5 mesh, they drive the limiting frame 7 inside the slide plate 6 to move synchronously on the inner wall of the arc-shaped groove 2. At this time, the reaction force of the spring 29 drives the rotating roller 12 to contact the material against the outer wall of the mold 14 for forming. Through the elasticity of the spring 29 and the sliding of the limiting rod 8, it is possible to easily form cups of different sizes. The effect of the process is that when material needs to be unloaded, the electric slide rail 15 drives the unloading rack 16 to move the roller 20 to the opening of the paper cup. When the electric slide rail 15 drives the unloading rack 16 to move in the opposite direction, the paper cup is pushed above the unloading rack 16 for unloading. At the same time, the cooperation of the limit rod 28 and the spring 19 enables the adaptive effect according to different molds 14. When it is necessary to change different molds 14, the spring 24 is retracted by pressing the locking block 23. The reaction force of the spring 327 drives the ejector block 26 to push the mounting frame 28, so that the mold 14 can be changed quickly.
