Abstract
Description
Technical Field
[0001] This utility model belongs to the field of paper cup processing technology, and specifically relates to a paper cup forming mechanism. Background Technology
[0002] Currently, both domestic and international standards require disposable cups to be environmentally friendly and biodegradable. Paper cup machines are specialized equipment for producing paper cups.
[0003] Because the paper cups are very thin, they are prone to folding during the process of being clamped and transferred from the feeding mechanism to the forming mechanism. This leads to an increase in the defect rate of the paper cups produced by the paper cup machine, which in turn increases the cost and reduces the production quality of the paper cup bottom forming process. Therefore, an improved forming mechanism for paper cup machines is provided. Utility Model Content
[0004] To address the problems mentioned in the background section, this invention provides a forming mechanism for a paper cup machine. This mechanism uses a clamping and feeding mechanism to deliver the bottom paper of the paper cup to the lower forming mold within the forming cavity, preventing folding during the transfer of the bottom paper to the forming mechanism and thus improving production quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper cup forming mechanism, including a processing platform, wherein a forming table is mounted on the processing platform via a mounting base, and four sets of forming cavities are formed around the forming table. A cylinder is installed at the bottom of each forming cavity, and the driving end of the cylinder passes through the forming cavity to drive and connect to the lower forming mold. A forming mechanism that is compatible with the lower forming mold is mounted on one end of the processing platform via a frame one, and a clamping and feeding mechanism is mounted on the other end of the processing platform via a frame two.
[0006] Furthermore, the clamping and dispensing mechanism includes a clamp, an electric telescopic rod, and a placement frame. A spring is installed at the bottom of the placement frame, and an extrusion plate is connected to the upper end of the spring. Unformed paper cup bottom paper is placed on the extrusion plate. Limiting rods for limiting the paper cup bottom paper are installed around the placement frame. A clamping opening is provided at the upper end of the placement frame. The electric telescopic rod is installed at the middle position of the top of the second frame. The telescopic end of the electric telescopic rod is driven and connected to a clamp for clamping the paper cup bottom paper.
[0007] Furthermore, the forming mechanism includes four hydraulic cylinders, and the bottom drive end of each hydraulic cylinder is connected to an upper forming mold that corresponds to the lower forming mold. The upper forming mold is driven by the hydraulic cylinder to descend into the forming cavity and cooperate with the lower forming mold to press the bottom paper of the paper cup into shape.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] 1) This utility model starts the electric telescopic rod to drive the clamp to send the paper cup bottom paper to the forming lower mold in the forming cavity; thereby preventing the paper cup bottom paper from easily folding during the transfer to the forming mechanism, reducing the defect rate of paper cup bottom production, and improving the production quality of paper cup bottom forming process.
[0010] 2) After feeding the material, start the motor to drive the forming table to rotate below the forming mechanism. Use the hydraulic cylinder to drive the upper forming mold to move downward and cooperate with the lower forming mold to press the bottom paper of the paper cup into shape, thus obtaining the bottom forming structure of the paper cup; this realizes a fast forming operation and improves the overall forming processing efficiency.
[0011] 3) After molding, the motor drives the molding table to rotate 90°, and then the cylinder drives the lower molding mold to push the molded paper cup bottom out of the molding cavity, so that the paper cup bottom can continue to be processed and produced. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0020] Please see Figures 1-4 This utility model provides the following technical solution: a paper cup forming mechanism, including a processing platform 1, on which a forming table 2 is mounted via a mounting base 11. Four sets of forming cavities 21 are formed around the forming table 2. A cylinder 43 is installed at the bottom of each forming cavity 21. The driving end of the cylinder 43 passes through the forming cavity 21 and drives a lower forming mold 44 connected thereto. A forming mechanism 4, compatible with the lower forming mold 44, is mounted on one end of the processing platform 1 via a frame 13. A clamping and dispensing mechanism 3 is mounted on the other end of the processing platform 1 via a frame 2 12. The clamping and dispensing mechanism 3 includes a clamp 31, an electric telescopic rod 32, and a placement rack 33. A spring 34 is installed at the bottom of the placement rack 33, and an extrusion plate 35 is connected to the upper end of the spring 34. Unformed paper cup bottom paper 6 is placed on the extrusion plate 35. Limiting rods 36 are installed around the perimeter of the placement frame 33 to limit the paper cup bottom paper 6. The upper end of the placement frame 33 is provided with a clamping port 37. An electric telescopic rod 32 is installed at the middle position of the top of the frame 12. The telescopic end of the electric telescopic rod 32 is connected to a clamp 31 for clamping the paper cup bottom paper 6. When feeding, the electric telescopic rod 32 is activated to drive the clamp 31 to pass through the clamping port 37 into the placement frame 33 to clamp the unformed paper cup bottom paper 6. Then, the electric telescopic rod 32 drives the clamp 31 to send the paper cup bottom paper 6 to the forming cavity 21. The clamp 31 is released to place the paper cup bottom paper 6 on the forming lower mold 44 inside the forming cavity 21. This prevents the paper cup bottom paper 6 from easily folding during the transfer to the forming mechanism, reduces the defect rate of paper cup bottom production, and improves the production quality of paper cup bottom forming.
[0021] In this embodiment, the forming mechanism 4 includes four hydraulic cylinders 41. The bottom drive end of each hydraulic cylinder 41 is connected to an upper forming mold 42, which corresponds to the lower forming mold 44. The upper forming mold 42 is driven down into the forming cavity 21 by the hydraulic cylinders 41 and cooperates with the lower forming mold 44 to press the bottom paper 6 of the paper cup into shape. After feeding, the motor 5 is started to drive the forming table 2 to rotate. After the forming table 2 rotates to a position below the forming mechanism 4, the hydraulic cylinders 41 are started to drive the upper forming mold 42 to move down into the forming cavity 21 and cooperate with the lower forming mold 44 to press the bottom paper 6 of the paper cup into shape, thus obtaining the bottom forming structure of the paper cup. This achieves rapid forming operation and improves the overall forming processing efficiency.
[0022] In this embodiment, a motor 5 is mounted on the mounting base 11 via a machine column, and the drive shaft end of the motor 5 is fixedly connected to the center of the bottom of the forming table 2.
[0023] In this embodiment, the lower forming mold 44 is driven by the cylinder 43 to push the formed paper cup bottom out of the forming cavity 21. After forming, the motor 5 drives the forming table 2 to rotate 90°, and then the cylinder 43 is activated to drive the lower forming mold 44 to push the formed paper cup bottom out of the forming cavity 21, so that the paper cup bottom can be continuously processed and produced.
[0024] In this embodiment, the processing platform 1 is equipped with a power supply box for supplying power to the motor 5, hydraulic cylinder 41, air cylinder 43, and electric telescopic rod 32.
[0025] The working principle and usage process of this utility model are as follows: When using this utility model, the operator first places the unformed paper cup bottom paper 6 on the extrusion plate 35 in the placement rack 33, compresses the spring 34, and limits the paper cup bottom paper 6 in the placement rack 33 through the limiting rod 36; when it is necessary to release the material, the electric telescopic rod 32 is activated to drive the clamp 31 to pass through the clamping port 37 into the placement rack 33 to clamp the unformed paper cup bottom paper 6, and then the electric telescopic rod 32 drives the clamp 31 to send the paper cup bottom paper 6 to the forming cavity 21, and the clamp 31 is released to place the paper cup bottom paper 6 on the forming lower mold 44 inside the forming cavity 21; thereby preventing the paper cup bottom paper 6 from easily folding during the transfer to the forming mechanism, reducing the defect rate of paper cup bottom production, and improving the production quality of paper cup bottom forming process.
[0026] After the material is fed in, the motor 5 is started to drive the forming table 2 to rotate. After the forming table 2 rotates, it moves to the bottom of the forming mechanism 4. The hydraulic cylinder 41 is started to drive the upper forming mold 42 to move downward into the forming cavity 21 and cooperate with the lower forming mold 44 to press the bottom paper 6 of the paper cup into shape, thus obtaining the bottom forming structure of the paper cup. This achieves rapid forming operation and improves the overall forming processing efficiency.
[0027] After molding, the motor 5 drives the molding table 2 to rotate 90°, and then the cylinder 43 drives the molding lower mold 44 to push the molded paper cup bottom out of the molding cavity 21, so that the paper cup bottom can be continuously processed and produced.
[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
