Description

Technical Field

[0001] This utility model relates to the technical field of paper cup forming, and in particular to a cup bottom forming mechanism. Background Technology

[0002] A paper cup forming machine is a paper container made by mechanically processing and bonding paper made from chemical wood pulp. It is cup-shaped in appearance. Currently, the cup body and cup bottom of paper cups are processed and formed separately. The cup bottom needs to provide support and requires circumferential folding. In the existing technology, the paper is usually punched to form a circular cup bottom blank, and then the circular bottom blank is sent to the folding process for folding. Since punching and folding are completed in two separate processes, the processing efficiency is low.

[0003] A search revealed Chinese patent publication number CN212288928U, which discloses a paper cup bottom punching and forming device. The device includes a mounting plate, a paper feed plate, a punching flange shaft, a push rod, a punch holder, and a lower punch die. Paper is fed into the paper feed plate through its inlet. A first power source drives the punching flange shaft axially, causing the punching die to engage with the lower punch die to punch the paper into a circular cup bottom blank. A second power source then drives the push rod axially along the punching flange shaft, thereby engaging the push die to push the cup bottom blank into the punch holder. In the mold cavity, since the mold cavity size of the lower die of the punch is larger than the mold cavity size of the punch holder, when the bottom pusher pushes the cup bottom blank into the punch holder, the cup bottom blank is folded along the punch holder to form the cup bottom. Based on this paper cup bottom punching and forming device, the cup bottom folding and forming can be completed simultaneously with the paper punching, and the cup bottom punching and folding can be formed in one step, which has a high processing efficiency. However, in actual use, the device can only process one cup bottom at a time. For two cup bottoms of different sizes, they need to be processed separately, which makes the efficiency low and the cost high. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cup bottom forming mechanism, which aims to improve the problem that the existing device can only process one cup bottom at a time. For two cup bottoms of different sizes, they need to be processed separately, which results in low efficiency and high cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cup bottom forming mechanism, comprising a worktable, a motor fixedly connected to the top of the inner wall of the worktable, a disc fixedly connected to the output end of the motor, a rotating rod rotatably connected to the top of the front side of the outer wall of the disc, a connecting rod rotatably connected to the bottom end of the rotating rod, a limiting tube fixedly connected to the front bottom side of the outer wall of the worktable, the connecting rod slidably connected to the limiting tube, a pressing plate fixedly connected to the bottom end of the connecting rod, a mounting plate fixedly connected to the top of the pressing plate, and a mounting plate fixedly connected to the bottom of the mounting plate. The device has a telescopic rod, with a connecting plate fixedly connected to the bottom end of the telescopic rod. Upper molds are fixedly connected to the bottom left and right sides of the connecting plate. A second motor is fixedly connected to the front side of the outer wall of the workbench. A rotating disk is fixedly connected to the top of the second motor. Reserved slots are provided around the top of the rotating disk. Lower molds are fixedly connected to the inner walls of the multiple reserved slots. Multiple air inlets are opened and closed on the left and right sides of the outer wall of the workbench. Two suction pumps are fixedly connected to the front end of the bottom of the inner wall of the workbench. A cleaning mechanism is provided in the middle of the front side of the outer wall of the workbench. The cleaning mechanism is used to clean paper scraps on the device.

[0006] The above technical solution works as follows: First, when the motor starts, its output drives the disc to rotate. During the rotation of the disc, the rotating rod connected to the disc moves accordingly. The bottom end of the rotating rod drives the connecting rod to slide up and down within the limiting tube. Since the bottom end of the connecting rod is connected to the pressing plate, it drives the pressing plate to move up and down, causing the upper mold at the bottom of the connecting plate to move down synchronously. At the same time, the second motor drives the rotating disc to rotate. When a forming operation is required, the corresponding lower mold is rotated to the position corresponding to the upper mold. When the pressing plate contacts the raw material paper, the telescopic rod extends, pushing the two upper molds to move down and cooperate with the lower mold located on the rotating disc to cut the raw material paper to complete the forming of the cup bottom. The air inlet is used to introduce external air, and the suction pump is used to generate suction, thereby sucking the formed cup bottom into the reserved groove.

[0007] As a further description of the above technical solution:

[0008] The cleaning mechanism includes a suction head, which is fixedly connected to the front side of the outer wall of the workbench. A delivery pipe is connected to the rear side of the outer wall of the suction head. A drawer is slidably connected to the bottom of the inner wall of the workbench. Air outlets are opened on both the drawer and the right side of the outer wall of the workbench. An air duct is fixedly connected to the right side of the outer wall of the workbench, and a fan is fixedly connected to the right end of the air duct.

[0009] The above technical solution works as follows: when the device stops running, the fan starts and generates suction. At this time, scraps of paper and other debris are sucked up by the suction head and then transported through the conveying pipe connected to it. The debris travels along the conveying pipe and finally enters the drawer that is slidably connected to the bottom of the inner wall of the workbench. The air outlets on the right side of the drawer and the outer wall of the workbench are used to balance the airflow to ensure smooth air circulation. The air duct is used to connect the fan and the workbench to ensure that the suction can be effectively transmitted.

[0010] As a further description of the above technical solution:

[0011] Two support rods are fixedly connected to the top front side of the workbench, and a display screen is fixedly connected to the top of the two support rods.

[0012] The above technical solution involves two support rods on the front side of the top of the workbench supporting the display screen, which can display the working parameters of the cup bottom forming mechanism in real time.

[0013] As a further description of the above technical solution:

[0014] A mounting base is fixedly connected to the top right side of the workbench, and an alarm light is fixedly connected to the inner wall of the mounting base.

[0015] The above technical solution involves a mounting bracket on the top right side of the workbench to secure an alarm light. When the equipment malfunctions, operates abnormally, or reaches its preset working limits, the alarm light will illuminate, alerting the operator to take timely action to avoid greater losses or safety hazards.

[0016] As a further description of the above technical solution:

[0017] An information board is provided on the top front side of the outer wall of the workbench. Each of the four sides of the outer wall of the information board is threaded with a screw, and the information board is threaded to the workbench through the screws.

[0018] The above technical solution involves fixing the information board to the top front side of the outer wall of the workbench with screw one. This board is used to record relevant equipment information. The connection method of screw one ensures that the information board is firmly installed, not easy to fall off, and convenient for operators to view at any time.

[0019] As a further description of the above technical solution:

[0020] A dustproof net is provided on the rear side of the outer wall of the workbench. Screws are threaded around the outer wall of the dustproof net, and the dustproof net is threaded to the workbench through the screws.

[0021] The above technical solution prevents external dust and other impurities from entering the workbench, protecting internal components from dust interference and ensuring normal equipment operation.

[0022] As a further description of the above technical solution:

[0023] The workbench has sliding grooves on the bottom left and right sides of its inner wall, and the drawer has sliders fixedly connected to the left and right sides of its outer wall. The two sliders are slidably connected to the corresponding air inlets.

[0024] The above technical solution involves sliding grooves on the left and right sides of the bottom of the inner wall of the workbench, which cooperate with the sliders on the left and right sides of the outer wall of the drawer. When the drawer needs to be inserted or pulled out, the sliders slide in the grooves. This sliding connection method ensures the smoothness and directionality of the drawer's movement, enabling it to be accurately installed or smoothly pulled out, and facilitating the cleaning of collected debris.

[0025] As a further description of the above technical solution:

[0026] A controller is fixedly connected to the top right side of the outer wall of the workbench. The controller is electrically connected to the first motor, the telescopic rod, and the second motor.

[0027] Through the above technical solution, the controller is electrically connected to motor one, telescopic rod and motor two respectively to control the operation of these components, thereby realizing operations such as starting, stopping, speed adjustment and telescopic length adjustment, so as to achieve the purpose of precisely controlling the cup bottom forming process.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the rotating disk driven by motor two quickly switches between different lower mold positions, and works in conjunction with the upper mold to achieve continuous operation, which greatly improves the production efficiency of cup bottoms. By changing the size of one of the two upper molds, two different sizes of cup bottoms can be manufactured at the same time, which increases the production flexibility of the equipment and meets the diverse market demands. In addition, the air inlet introduces air and the suction pump generates suction, which ensures that the formed cup bottoms can be stably transported to the reserved slot, avoiding positional deviation and falling, and facilitating the smooth progress of subsequent operations.

[0030] 2. In this utility model, a powerful suction force is generated by the operation of a fan, and debris is collected into a drawer through a suction head and a conveying pipe. The operation is convenient and efficient. This not only reduces the risk of equipment failure due to debris accumulation and extends its service life, but also eliminates potential safety hazards. The cleaned work area is clean and orderly, creating conditions for quick production when the machine is turned on again, improving overall work efficiency and creating a good production environment.

[0046] Reference Figure 1 , Figure 3 and Figure 4 The bottom left and right sides of the inner wall of the workbench 1 are provided with sliding grooves 27. The sliding grooves 27 are used to guide the sliding of the drawer 203. The left and right sides of the outer wall of the drawer 203 are fixedly connected with sliders 28. The sliders 28 are used to slide in the sliding grooves 27. The two sliders 28 are respectively slidably connected to the corresponding air inlets 17. The top right side of the outer wall of the workbench 1 is fixedly connected with a controller 29. The controller 29 is used to control the operation of the equipment. The controller 29 is electrically connected to motor 4, telescopic rod 10 and motor 13 respectively.

[0047] Specifically, the sliding grooves 27 on the left and right sides of the bottom of the inner wall of the workbench 1 cooperate with the sliders 28 on the left and right sides of the outer wall of the drawer 203. When the drawer 203 needs to be inserted or pulled out, the sliders 28 slide in the sliding grooves 27. This sliding connection method ensures the smoothness and directionality of the drawer 203's movement, enabling it to be accurately installed or smoothly pulled out, facilitating the cleaning of collected debris. The controller 29 is electrically connected to the motor 4, the telescopic rod 10, and the motor 13, respectively, to control the operation of these components, thereby realizing operations such as starting, stopping, speed adjustment, and telescopic length adjustment, so as to achieve precise control of the cup bottom forming process.

[0048] Working principle: After motor 4 starts, its output drives the disc 5 to rotate in a circular motion. Since the disc 5 is rotatably connected to the rotating rod 6, the rotation of the disc 5 changes the position of the connection point between the rotating rod 6 and the disc 5, thereby driving the rotating rod 6 to move. The bottom end of the rotating rod 6 is rotatably connected to the connecting rod 7, so the movement of the rotating rod 6 causes the connecting rod 7 to slide linearly up and down within the limiting tube 3. The bottom end of the connecting rod 7 is fixed with the pressing plate 8, so the pressing plate 8 will move up and down synchronously with the connecting rod 7. The bottom of the connecting plate 11 connected to the pressing plate 8 is equipped with the upper mold 12, so the upper mold 12 will move up and down with the pressing plate 8. At the same time, motor 2 13 drives the rotating disc 14 to rotate. When it is necessary to perform... During the cup bottom forming operation, the rotation of the rotating disk 14 rotates the appropriate lower mold 16 to the position corresponding to the upper mold 12. When the pressing plate 8 contacts the raw material paper, the telescopic rod 10 extends, further driving the upper mold 12 to move downward precisely, so that the two upper molds 12 and the lower mold 16 located on the rotating disk 14 are closely matched to accurately cut the raw material paper and complete the cup bottom forming work. During this process, the air inlet 17 introduces external air into the worktable 1, and the suction pump 18 is started to generate suction. After the cup bottom is formed, the suction of the suction pump 18 can suck the formed cup bottom into the reserved groove 15 opened around the top of the rotating disk 14 for subsequent operations or processing.

[0049] Furthermore, after the cup bottom forming mechanism stops operating, in order to clean up the paper scraps and other debris generated during the operation, the blower 206 starts to run. When the blower 206 is working, it will create a negative pressure inside, thereby generating a strong suction force. Due to the suction force, the suction head 201 near the debris location sucks in the surrounding paper scraps and other debris. These sucked-in debris will move along the conveying pipe 202 connected to it. The conveying pipe 202 guides the debris to the drawer 203 at the bottom of the inner wall of the workbench 1, realizing the collection of debris.
