Description

Technical Field

[0001] This utility model relates to the field of paper bowl processing technology, specifically to a forming machine for paper bowl processing. Background Technology

[0002] The forming machine for paper bowls is a special equipment used to process paper into paper bowls with specific shapes and specifications through processes such as feeding, molding, heating and shaping, and trimming. It can realize the automated forming process of paper bowls from raw materials to finished products.

[0003] Existing paper bowl forming machines typically use heat conduction to heat the hot melt adhesive film between the bowl body and the bottom for bonding. Due to the slow heat transfer during the heat conduction process, it takes a long time for the hot melt adhesive film to reach the molten state required for effective bonding from its initial state. The traditional heat conduction heating method results in uneven heat distribution, with some areas not fully melting and failing to bond effectively, which greatly affects the quality and efficiency of paper bowl bonding. Furthermore, after the hot melt adhesive film melts and when the paper bowl is squeezed by the mold, it will become stuck and adhere to the mold. The lack of an effective demolding structure increases the difficulty of separating the paper bowl from the mold. Forcibly demolding not only consumes a lot of time and manpower, but also easily causes damage and deformation to the surface of the paper bowl. Utility Model Content

[0019] This utility model discloses a forming machine for processing paper bowls.

[0020] This utility model provides, for example Figure 1-3The paper bowl forming machine shown includes a base 1. A processing plate 2 is fixedly connected to the top of the base 1 via a rotating support mechanism. The top of the processing plate 2 has multiple conical placement openings 3. An L-shaped bracket 4 is fixedly connected to one end of the top of the base 1. A first cylinder 5 is fixedly connected to the cavity of one end of the L-shaped bracket 4. An upper conical mold shell 6 is fixedly connected to the bottom of the first cylinder 5. A second cylinder 7 is fixedly connected to the cavity of one end of the top of the base 1. One end of the second cylinder 7 passes through the top of the base 1 and is fixedly connected to a lower mold shell 8. A first ultrasonic component 9 is fixedly connected inside the cavity of the upper conical mold shell 6. The vibration output end of the first ultrasonic component 9 passes through the bottom of the upper conical mold shell 6 and is fixedly connected to an ultrasonic template 10. A second ultrasonic component 11 is fixedly connected to both ends of the cavity of the lower mold shell 8. The vibration output ends of the second ultrasonic components 11 at both ends pass through the top of the lower mold shell 8 and are fixedly connected to an arc-shaped ultrasonic template 12. Air guide cavities 13 are provided inside the cavities of both the upper conical mold shell 6 and the lower mold shell 8. Multiple demolding air jet holes 14 are provided on the outer wall of the upper conical mold shell 6 and the top of the lower mold shell 8. A power supply mechanism is fixedly connected to the upper conical mold shell 6 and the lower mold shell 8 inside the cavity of the base 1. A control display 15 is fixedly connected to the side wall of the base 1. The rotating support mechanism can drive the processing disc 2 to rotate, facilitating continuous multi-station processing and improving production efficiency. The conical placement port 3 is used to position the paper bowl material to ensure molding accuracy. The first cylinder 5 and the second cylinder 7 are used to... The upper conical mold shell 6 and lower mold shell 8 are driven separately to achieve precise pressing, positioning, and forming of the paper bowl. The first ultrasonic component 9 and the second ultrasonic component 11 generate heat through high-frequency vibration. Compared with traditional heat conduction methods, the heat transfer is rapid and uniform, which can quickly melt the adhesive parts of the paper bowl material, greatly improving the adhesion efficiency and quality. The ultrasonic template 10 and the arc-shaped ultrasonic template 12 can be used directly on the forming part of the paper bowl to ensure the forming effect. The air guide cavity 13, together with the demolding air hole 14, can spray gas under the action of the power supply mechanism to effectively blow away the paper bowls that are stuck to the mold, solving the problem of difficult demolding. The control display 15 allows the operator to monitor and adjust the working parameters of the forming machine in real time, ensuring the stability and reliability of the processing process. This solves the problems of slow heat transfer and uneven distribution during heating and forming of existing paper bowl processing forming machines, which lead to low adhesion efficiency and easy jamming and adhesion between the paper bowl and the mold, causing demolding difficulties.

[0021] In order to drive the processing disc 2 to rotate smoothly, such as Figure 1 and 2As shown, the rotating support mechanism includes a support chamber 16, a support column 17, and a control motor 18. The support chamber 16 is fixedly connected to the top of the base 1, and the support column 17 is rotatably connected inside the cavity of the support chamber 16. The top of the support column 17 is fixedly connected to the bottom of the processing tray 2, and the control motor 18 is fixedly connected to the bottom of the cavity of the support chamber 16. One end of the control motor 18 is fixedly connected to the bottom of the support column 17. The control motor 18 drives the support column 17 to rotate, thereby driving the processing tray 2 to rotate smoothly, realizing the automated flow of paper bowl processing and reducing manual intervention.

[0022] To provide a stable air supply for the demolding air jet 14, such as Figure 1 and 2 As shown, the power supply mechanism includes a fan 19, a first power supply hose 20, and a second power supply hose 21.

The other end of the first power supply hose 20 is fixedly connected to the input port of the lower mold shell 8, and the other end of the second power supply hose 21 is fixedly connected to the input port of the upper conical mold shell 6. The fan 19 generates high-pressure airflow, which is delivered to the air guide cavity 13 of the upper conical mold shell 6 and the lower mold shell 8 through the first power supply hose 20 and the second power supply hose 21, respectively. This provides a stable air source for the demolding spray hole 14, ensuring efficient demolding. At the same time, the airflow in the air guide cavity 13 can also help dissipate heat from the mold and maintain the normal operating temperature of the mold.

[0023] To achieve automatic material feeding, such as Figure 1 As shown, a third cylinder 22 is fixedly connected to the other end of the top of the base 1, and a feeding top plate 23 is fixedly connected to the top of the third cylinder 22. The feeding top plate 23 is driven to move upward by the third cylinder 22, which can push the formed paper bowl out from the conical placement opening 3 of the processing plate 2, realize automatic feeding, reduce the manual material handling process, further improve production efficiency, and reduce labor intensity.

[0024] To prevent the paper bowls from being damaged by friction during molding and demolding, such as Figure 1-3 As shown, the surfaces of the conical placement port 3, the upper conical mold shell 6, and the lower mold shell 8 are all coated with anti-wear silicone. The anti-wear silicone coating can effectively reduce the friction between the paper bowl material and the mold surface, prevent the paper bowl from being damaged by friction during molding and demolding, reduce mold wear, extend the mold service life, and reduce equipment maintenance costs.

[0025] To achieve ultrasonic heating and prevent the paper bowl from being damaged by collision due to excessive expansion and contraction, such as Figure 1-3As shown, both the first ultrasonic component 9 and the second ultrasonic component 11 consist of an ultrasonic generator, a transducer, and an amplitude transformer. The outer walls of the upper conical mold shell 6 and the lower mold shell 8 are fixedly connected with limit protection rings 24. The ultrasonic components consisting of the ultrasonic generator, transducer, and amplitude transformer can efficiently convert electrical energy into high-frequency mechanical vibration, generating stable and concentrated heat to meet the heating requirements of paper bowl forming. The limit protection rings 24 provide a certain degree of protection for the mold, preventing the paper bowl from being damaged by collision during the expansion and contraction process.
