Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper bowl processing technology, specifically to a paper bowl machine edge forming mechanism. Background Technology
[0002] Paper bowls are a common type of paper container, widely used in food packaging, catering services, and disposable tableware. They offer advantages such as being environmentally friendly, lightweight, and low-cost. During the production process, the edges of the paper bowl need to be rolled and shaped to enhance its edge strength and aesthetics. The existing technology (authorized publication number CN 217124110) addresses this. U's patent discloses an automatic edge-rolling device for an environmentally friendly paper cup forming machine, including a worktable. A working plate for edge rolling is mounted on the upper end of the worktable via a first rotating block. A working groove is formed on the surface of the working plate, and a picking mechanism is installed inside the working groove. Hydraulic cylinders are installed on both sides of the working plate. While this device can change the corresponding edge-rolling block according to the paper cup model, the fixed size of the working groove causes the paper cups to shift or wobble during edge rolling. This results in inconsistent force and angle on the paper cups, leading to some edge rolls being too thick or too thin, thus reducing the edge rolling quality of the paper cups. Therefore, we propose an edge-rolling forming mechanism for a paper cup machine. Utility Model Content

The return spring 58 is movably sleeved with the longitudinally corresponding guide slide post 52, which can limit and fix different types of paper bowls, ensuring that the position of the paper bowl will not shift or shake during the edge rolling process. This solves the problem of some edges being too thick or too thin due to different edge rolling force and angle, and further improves the edge rolling quality of the paper bowl.
[0021] It also includes a control switch group 3, which is located at the front end of the fixed base 2. The input end of the control switch group 3 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.
[0022] Trapezoidal blocks 8 are provided at the middle of the front end of the mounting plate 53 and the middle of the rear end of the push plate 55. A vertical plate 6 is slidably connected to the rear side of the bottom wall of the fixed base 2. A top plate 7 is provided on the upper side of the left end of the vertical plate 6. The right ends of the two trapezoidal blocks 8 are in contact with the inclined surface provided on the left end of the top plate 7. During the rotation of the screw 9, the vertical plate 6 will be driven to move to the left through the threaded connection. During the movement of the vertical plate 6, the top plate 7 will be driven to move to the left. At this time, the front trapezoidal block 8 is pushed by the top plate 7 and begins to drive the rear clamping plate 57 to move forward through the push plate 55. The rear trapezoidal block 8 is pushed by the top plate 7 and begins to drive the connecting plate 54 to move backward through the mounting plate 53.
[0023] The fixed base 2 has a screw 9 rotatably connected to its lower side. The vertical plate 6 is threaded to the right side of the outer arc surface of the screw 9 through a threaded hole on its lower right end. The fixed base 2 has a motor 10 on its lower right side. The left end of the output shaft of the motor 10 is fixedly connected to the right end of the screw 9. The input end of the motor 10 is electrically connected to the output end of the control switch group 3. The motor 10 starts to run when the control switch group 3 is adjusted, and the output shaft of the motor 10 drives the screw 9 to rotate.
[0024] The base 1 has a mounting bracket 11 on its upper rear side, an electric push rod 12 on its lower front side, a connecting seat 13 at the lower end of the telescopic end of the electric push rod 12, a mold base 14 placed in a clearance groove in the middle of the lower end of the connecting seat 13, the mold base 14 corresponding to the placement groove 4 in its vertical position, slots on the upper right side of the mold base 14, and insert rods 16 slidably connected in the mounting groove in the middle of the right side of the connecting seat 13, the left ends of the two insert rods 16 respectively inserting into the horizontally adjacent slots, and the right ends of the insert rods 16 are respectively... The left end of the fixing plate 17 is fixedly connected to the fixing plate 17. A spring 18 is provided between the left end of the fixing plate 17 and the right end of the connecting seat 13. The spring 18 is sleeved on the outside of the right side of the insertion rod 16. The input end of the electric push rod 12 is electrically connected to the output end of the control switch group 3. After placing the mold seat 14 of the corresponding model at the lower end of the connecting seat 13, the fixing plate 17 is released. The tension generated by the contraction of the spring 18 can drive the insertion rod 16 to move to the left and reset through the fixing plate 17, so that the insertion rod 16 is inserted into the inside of the slot, thereby realizing the installation and fixation of the mold seat 14.
[0025] The working principle of the edge-rolling forming mechanism of the paper bowl machine provided by this utility model is as follows: Before use, first pull the fixing plate 17 to the right. The fixing plate 17 drives the insertion rod 16 to move to the right, and the spring 18 extends. Then, place the mold seat 14 of the corresponding model at the lower end of the connecting seat 13. At this time, release the fixing plate 17. The tension generated by the contraction of the spring 18 can drive the insertion rod 16 to move to the left and reset through the fixing plate 17, so that the insertion rod 16 is inserted into the inside of the slot, thereby realizing the installation and fixation of the mold seat 14. In the subsequent use of the edge-rolling forming mechanism of the paper bowl machine, first put the paper bowl corresponding to the model of the mold seat 14 into the inside of the placement slot 4. Then, through the regulation of the control switch group 3, the motor 10 starts to run. The output shaft of the motor 10 drives the screw 9 to rotate. During the rotation of the screw 9, it will drive the vertical plate 6 to move to the left through the threaded connection. During the movement of the vertical plate 6... During the process, the top plate 7 will move to the left. At this time, the front trapezoidal block 8 will be pushed by the top plate 7 and will start to move the rear clamping plate 57 forward through the push plate 55. The rear return spring 58 will contract. The rear trapezoidal block 8 will be pushed by the top plate 7 and will start to move the connecting plate 54 backward through the mounting plate 53. The connecting plate 54 will move the front clamping plate 57 backward. The front return spring 58 will contract, which will cause the gap between the two clamping plates 57 to gradually decrease. Finally, the clamping plate 57 will limit and fix the paper bowl. Then, through the control switch group 3, the electric push rod 12 will start to run. The telescopic end of the electric push rod 12 will extend, which will cause the connecting seat 13 to drive the mold seat 14 to move downward. Finally, the forming groove 15 will contact the edge of the paper bowl. Subsequently, under the pressure of the mold seat 14, the edge of the paper bowl will curl, thereby forming the required curled edge shape.
[0026] It is worth noting that the motor 10 disclosed in the above embodiments can be ECMA-C20604RS, the electric push rod 12 can be DYTFD2000-550 / 45, and the control switch group 3 is provided with control buttons corresponding to the motor 10 and the electric push rod 12 for controlling their switching.
