Description

Technical Field

[0001] This utility model relates to the field of paper cup forming technology, specifically a paper cup forming device. Background Technology

[0002] Paper cups, as a common disposable beverage container, are widely used in daily life and business activities. With the continuous growth of market demand, the requirements for paper cup production efficiency and quality are also increasing.

[0003] Chinese Patent Publication No. CN222310001U discloses a coating paper cup bonding and forming device, which includes a support mechanism. A motor is fixedly mounted on the upper end of the support mechanism, an bonding mechanism is fixedly mounted in the middle of the support mechanism, and an auxiliary mechanism is fixedly mounted on the lower end of the support mechanism. In this utility model, the device, through the arrangement of a motor, a fixed plate, a support column, a worktable, a placement groove, a rotating column, a cylinder, and a rotating disk, allows the user to place the cup body onto the outer surface of the support column and place the cup bottom into the placement groove. At this time, the operation of the cylinder drives the worktable to rise and fall, causing the support column to insert into the placement groove so that the cup body and cup bottom come into contact.

[0004] In practical applications, although this device employs a technical solution where the cup body is fitted over the outer end of a support column, and the support column is inserted into a placement groove to achieve contact between the cup body and the bottom of the cup for adhesion, it has significant shortcomings. The formed paper cups remain fitted over the support column, requiring manual unloading one by one. This greatly reduces the unloading efficiency of the formed paper cups and severely impacts the overall performance of the device. Therefore, it is necessary to provide a paper cup forming device to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a paper cup forming device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A paper cup forming apparatus, comprising:

[0008] The workbench has a base frame fixedly installed at its bottom and a forming mechanism installed at its top. Symmetrically distributed support columns are fixedly installed on both sides of the top of the workbench. A top plate is fixedly installed at the top of the support columns. An electric telescopic rod is rotatably installed at the bottom of the top plate. An upper movable plate is fixedly installed at the drive end of the electric telescopic rod. Several mounting slots are evenly and equidistantly opened on the outer side of the bottom of the upper movable plate.

[0009] The upper movable plate has an annular groove inside, which is connected to the interior of the mounting groove. A slide rod is fixedly installed inside the mounting groove. Symmetrically distributed movable blocks are sleeved on the outer wall of the slide rod, and the movable blocks are slidably installed on the mounting groove. A spring is sleeved on the outer wall of the slide rod between two movable blocks. Limit frames are fixedly installed at the bottom of both movable blocks, and a connecting column is fixedly installed at the top of one of the movable blocks.

[0010] A guide hole corresponding to the position and number of the connecting column is opened on one side of the inner wall of the annular groove. An annular rotating plate is rotatably installed on the outer perimeter of the upper movable plate. A pull rope is fixedly installed on the outer wall of the connecting column, and one end of the pull rope passes through the guide hole and is fixedly connected to the inner surface of the annular rotating plate.

[0011] Preferably, the bottom of the top plate is provided with a plurality of equidistant and evenly distributed limiting telescopic rods, and the telescopic ends of the limiting telescopic rods are fixedly connected to the top of the upper movable plate. The top of the limiting telescopic rods is fixedly installed with limiting blocks, and the bottom of the top plate is provided with an annular slide rail, and the annular slide rail is slidably connected to the limiting blocks.

[0012] Preferably, the forming mechanism includes a rotating shaft, which is rotatably mounted on the top of the worktable. A lower movable plate is fixedly mounted on the top of the rotating shaft. The top of the lower movable plate has placement slots corresponding to the position and number of mounting slots. A first gear is fixedly mounted on the outer wall of the rotating shaft. A servo motor is fixedly mounted on one side of the bottom of the worktable. The drive end of the servo motor passes through the worktable and extends to the top of the worktable. A second gear is fixedly mounted on the drive end of the servo motor, and the second gear meshes with the first gear.

[0013] Preferably, the limiting block is a T-shaped mechanism and is adapted to the annular slide.

[0014] Preferably, the movable block has a sliding hole adapted to the slide rod, and the movable block is slidably connected to the slide rod through the sliding hole.

[0015] Preferably, a number of vertical anti-slip strips are adhered to the outer surface of the annular rotating plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model utilizes a combination of a placement groove, a lower movable plate, a servo motor, a second gear, an electric telescopic rod, a rotating shaft, an annular groove, an installation groove, a pull rope, a movable block, a spring, a sliding rod, a connecting column, and a guide hole. After the paper cups are glued, rotating the annular plate reduces the distance between the two limiting frames, thus eliminating their supporting and limiting function inside the paper cup. The paper cup then automatically detaches under its own weight. Because the rotation of the annular plate can simultaneously adjust the distance between each set of limiting frames, the unloading of the formed paper cups can be completed in one operation, avoiding the tedious operation of unloading each cup individually. This significantly improves the unloading efficiency of the formed paper cups and ensures the overall performance of the device.

[0018] 2. This utility model utilizes the combined use of a limiting telescopic rod, a limiting block, and an annular slide rail. During device operation, the rotation of the lower and upper movable plates drives the limiting telescopic rod and the electric telescopic rod to rotate synchronously. The rotation of the limiting telescopic rod causes the limiting block to slide on the annular slide rail. Furthermore, when the electric telescopic rod drives the upper movable plate to move vertically, the upper movable plate automatically extends and retracts the telescopic end of the limiting telescopic rod. The rational design of the limiting telescopic rod effectively enhances the stability of the upper movable plate during vertical movement or rotation, thereby improving the stability and reliability of the entire device and possessing high practical value.

[0029] Please see Figures 1-5 One embodiment provided by this utility model:

[0030] A paper cup forming apparatus, comprising:

[0031] Workbench 1, with a base frame 2 fixedly installed at the bottom of the workbench 1, a forming mechanism set at the top of the workbench 1, symmetrically distributed support columns 3 fixedly installed on both sides of the top of the workbench 1, a top plate 8 fixedly installed at the top of the support columns 3, an electric telescopic rod 14 rotatably installed at the bottom of the top plate 8, an upper movable plate 7 fixedly installed at the drive end of the electric telescopic rod 14, and several mounting slots 19 evenly and equidistantly opened on the outer side of the bottom of the upper movable plate 7.

[0032] The upper movable plate 7 has an annular groove 18 inside, and the annular groove 18 is connected to the interior of the mounting groove 19. A slide rod 23 is fixedly installed inside the mounting groove 19. Symmetrically distributed movable blocks 21 are sleeved on the outer wall of the slide rod 23, and the movable blocks 21 are slidably installed on the mounting groove 19. A spring 22 is sleeved on the outer wall of the slide rod 23 between the two movable blocks 21. A limit frame 4 is fixedly installed at the bottom of each of the two movable blocks 21, and a connecting column 24 is fixedly installed at the top of one movable block 21.

[0033] A guide hole 25 corresponding to the position and number of the connecting column 24 is provided on one side of the inner wall of the annular groove 18. An annular rotating plate 5 is rotatably installed on the outer perimeter of the upper movable plate 7. A pull rope 20 is fixedly installed on the outer wall of the connecting column 24, and one end of the pull rope 20 passes through the guide hole 25 and is fixedly connected to the inner surface of the annular rotating plate 5.

[0034] The bottom of the top plate 8 is provided with several equidistant and evenly distributed limiting telescopic rods 13, and the telescopic ends of the limiting telescopic rods 13 are fixedly connected to the top of the upper movable plate 7. The top of the limiting telescopic rods 13 is fixedly installed with limiting blocks 15. The bottom of the top plate 8 is provided with an annular slide 16, and the annular slide 16 is slidably connected to the limiting blocks 15.

[0035] In one embodiment, the molding mechanism includes a rotating shaft 17, which is rotatably mounted on the top of the worktable 1. A lower movable plate 10 is fixedly mounted on the top of the rotating shaft 17. The top of the lower movable plate 10 has placement slots 9 corresponding to the position and number of mounting slots 19. A first gear 6 is fixedly mounted on the outer wall of the rotating shaft 17. A servo motor 11 is fixedly mounted on one side of the bottom of the worktable 1. The drive end of the servo motor 11 passes through the worktable 1 and extends to the top of the worktable 1. A second gear 12 is fixedly mounted on the drive end of the servo motor 11, and the second gear 12 meshes with the first gear 6.

[0036] In one preferred embodiment, the limiting block 15 is a T-shaped mechanism and is adapted to the annular slide 16, which can prevent the limiting block 15 from falling out of the slide, ensure stable sliding when the upper movable plate 7 rotates, and improve the operating stability of the device.

[0037] In one embodiment, the movable block 21 has a sliding hole adapted to the slide rod 23, and the movable block 21 is slidably connected to the slide rod 23 through the sliding hole.

[0038] In one preferred embodiment, several vertical anti-slip strips are adhered to the outer surface of the annular rotating plate 5, which can increase friction, facilitate the rotation of the annular rotating plate 5 by the operator, and improve the ease of operation and efficiency.

[0039] The working principle of this utility model is as follows: all electrical components mentioned in this article are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer for control, and existing publicly disclosed power connection technologies are not described in detail here. Parts not mentioned in this device are the same as existing technologies or can be implemented using existing technologies. During use, the cup body is placed on the outside of the two limiting brackets 4. With the help of the elastic force of the spring 22, the two movable blocks 21 are opened to the end positions inside the mounting groove 19. The movement of the movable blocks 21 drives the limiting brackets 4 to move, thereby making the two limiting brackets 4 firmly fix the cup body to its outer surface inside the cup body. At the same time, the bottom of the cup is placed in the placement groove 9. By controlling the drive end of the electric telescopic rod 14, the upper movable plate 7 is raised and lowered, causing the upper movable plate 7 to move downward and engage with the top of the lower movable plate 10. The movement of the upper movable plate 7 causes the bottom limiting bracket of the cup body, which is placed on the outer surface of the limiting bracket 4, to move downward, causing the limiting bracket 4 and the cup body to be inserted into the placement groove 9 and contact the bottom of the cup. When the cup body contacts the cup bottom, a heating mechanism inside the lower movable plate 10 heats the cup, melting the adhesive on the cup bottom and bonding the cup body to the cup bottom. During the bonding process, the servo motor 11 is activated, and its drive end rotates the second gear 12. Through the meshing of the second gear 12 with the first gear 6, the first gear 6 drives the rotating shaft 17 to rotate, which in turn drives the lower movable plate 10 to rotate. The rotation of the lower movable plate 10 then drives the upper movable plate 7 to rotate, thereby distributing the melted adhesive more evenly and improving the bonding quality between the cup body and the cup bottom. After the paper cup is bonded, the upper movable plate 7 is moved upward, and the bonded paper cup is removed from the placement slot 9 by the limiting frame 4. At this time, the worker places a tray on top of the lower movable plate 10 and rotates the annular rotating plate 5. The rotation of the annular rotating plate 5 pulls the pull rope 20. The movement of the pull rope 20 drives the movable block 21 at its bottom to move to another movable block 21 through the connecting column 24. This shortens the distance between the two movable blocks 21 and compresses the spring 22. As the inner movable block 21 moves, the distance between the two limiting frames 4 decreases, thereby causing the two limiting frames 4 to lose their supporting and limiting function inside the paper cup. The paper cup automatically falls off under its own weight. Since the rotation of the annular rotating plate 5 can simultaneously adjust the distance between each set of limiting frames 4, the unloading operation of the formed paper cups can be completed in one go, avoiding the tedious operation of unloading one by one by the worker. This significantly improves the unloading efficiency of the formed paper cups and ensures the overall efficiency of the device.

[0040] During device operation, the rotation of the lower movable plate 10 and the upper movable plate 7 causes the limiting telescopic rod 13 and the electric telescopic rod 14 to rotate synchronously. The rotation of the limiting telescopic rod 13 causes the limiting block 15 to slide on the annular slide rail 16. Furthermore, when the electric telescopic rod 14 drives the upper movable plate 7 to move vertically, the upper movable plate 7 automatically extends and retracts the telescopic end of the limiting telescopic rod 13. The reasonable design of the limiting telescopic rod 13 effectively enhances the stability of the upper movable plate 7 during vertical movement or rotation, thereby improving the stability and reliability of the entire device and demonstrating high practical value.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
