Description

Technical Field

[0001] This utility model relates to the field of paper cup production technology, and in particular to an automatic die-cutting device for double-sided coated paper cup-shaped cardboard. Background Technology

[0002] Paper cups are paper containers made by mechanically processing and bonding paper made from chemical wood pulp. They are cup-shaped in appearance. Paper cups for frozen foods are coated with wax and can hold ice cream, jam, butter, etc. Paper cups for hot drinks are coated with plastic. Paper cups are characterized by safety, hygiene, lightness, and convenience. They can be used in public places, restaurants, and eateries and are disposable items. Paper cups are divided into single-sided PE-coated paper cups and double-sided PE-coated paper cups. Paper cups made with double-sided PE-coated paper are called double-sided PE-coated paper cups. They are characterized by PE coating on both the inner and outer surfaces. In the processing of disposable paper cups, a die-cutting machine is used to cut the paper cup raw material into fan shapes. The working principle of the die-cutting machine is to use tools such as die-cutting blades to punch and cut the paper to obtain the desired paper shape.

[0003] A paper cup die-cutting machine is disclosed in Chinese utility model patent with announcement number CN221022545U, including a base, a material discharge box installed at the top front end of the base, a support frame fixedly connected to the top of the base, fixed plates fixedly connected to both sides of the top of the support frame, a transmission mechanism installed between the two fixed plates, a stamping groove installed on the top of the transmission mechanism, a first support seat fixedly connected to one side of the top of the support frame, and a stamping mechanism installed on the top of the first support seat.

[0004] Regarding the aforementioned technology, the inventors believe that the following drawbacks exist: The device drives a lead screw via a drive motor to rotate, which in turn drives a rolling nut seat to move the stamping groove below the stamping mechanism. Subsequently, the stamping mechanism cuts the cardboard in the stamping groove into a fan shape. During this process, the operator needs to frequently move the rolling nut seat forward and backward using the drive motor. Furthermore, the lead screw-driven mechanism results in a slow movement speed of the rolling nut seat, leading to decreased work efficiency and consequently reducing overall work productivity. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an automatic die-cutting device for double-sided coated paper cup-shaped cardboard.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic die-cutting device for double-sided coated paper cup-shaped cardboard, comprising a base, a rotating seat with an open top fixedly disposed on the upper surface of the base, a worktable rotatably disposed inside the rotating seat, a plurality of stamping grooves being arranged in a circumferential array on the upper surface of the worktable, a support frame with an L-shaped cross-section fixedly disposed on the upper surface of the base, a stamping cylinder fixedly disposed on the upper surface of the support frame, the piston rod of the stamping cylinder passing through the support frame, a stamping cutter for cutting coated paperboard being fixedly disposed at the end of the piston rod of the stamping cylinder, and a driving device for intermittently rotating the worktable disposed inside the rotating seat, the driving device comprising a control component and a driving component.

[0007] By adopting the above technical solution, when workers need to cut cardboard into fan shapes, they place the cardboard into the stamping groove. Then, the worker activates the stamping cylinder, causing the piston rod to move downwards. This piston rod then drives the stamping cutter downwards to cut the cardboard into fan shapes. After cutting, the worker activates the drive device, which causes the worktable to rotate intermittently, aligning other stamping grooves with the stamping cutter. This process improves the efficiency of cardboard cutting, thereby increasing the worker's overall work efficiency.

[0008] Furthermore, the control component includes a connecting rod fixedly mounted on the bottom surface of the workbench, a connecting plate fixedly mounted on the bottom surface of the connecting rod, and multiple mounting rods arranged in a circumferential array on the bottom surface of the connecting plate.

[0009] Furthermore, the drive assembly includes a motor fixedly mounted on the inner bottom wall of the rotating seat, a rotating rod fixedly mounted on the end of the motor output shaft, and a drive rod fixedly mounted on the outer wall of the rotating rod. The side wall of the drive rod abuts against the side wall of the mounting rod, and the axis of the rotating rod is parallel to the axis of the connecting rod.

[0010] By adopting the above technical solution, when the operator needs to drive the worktable to rotate intermittently, the operator needs to start the motor, which in turn rotates the motor output shaft. This causes the rotating rod to rotate under the action of the motor output shaft, which in turn causes the drive rod to rotate under the action of the rotating rod. This causes the side wall of the drive rod to gradually approach and eventually abut against the side wall of one of the mounting rods. Consequently, the mounting rod rotates along the axis of the connecting plate under the action of the drive rod, causing the connecting plate to rotate under the action of the mounting rod, which in turn causes the connecting rod to rotate under the action of the connecting plate. This, in turn, causes the worktable to rotate under the action of the connecting rod. During this process, [the following text appears to be unrelated and possibly a separate sentence fragment: "by..."] Figure 3 and Figure 4As shown, the axis of the rotating rod is parallel to the axis of the connecting rod. When the worktable rotates 90°, the driving rod and the mounting rod separate, thereby stopping the worktable from rotating. This allows the stamping groove to be aligned with the stamping tool, which improves the efficiency of the workers in cutting cardboard and thus increases their work efficiency.

[0011] Furthermore, an annular groove is provided on the inner wall of the rotating seat, and an annular block is rotatably disposed in the annular groove, the annular block being fixed to the worktable.

[0012] By adopting the above technical solution, when the worktable rotates, the annular block rotates under the action of the worktable. During this process, the annular block limits the worktable, thereby reducing the probability of the worktable moving up and down, and thus improving the stability of the device.

[0013] Furthermore, a limiting disk is fixedly provided on the outer wall of the rotating rod, and multiple limiting grooves are formed in a circumferential array on the bottom surface of the connecting disk, and the limiting disk and the limiting grooves rotate relative to each other.

[0014] By adopting the above technical solution, when the rotating rod rotates, the limiting plate rotates synchronously with the rotating rod; when the connecting plate rotates, the limiting plate rotates relative to the limiting groove, thereby reducing the probability of shaking when the connecting plate rotates and thus improving the stability of rotation. Furthermore, by... Figure 4 As shown, the limiting plate is semi-circular, which reduces the probability of collision between the limiting plate and the limiting groove, thereby further improving the stability of the device.

[0015] Furthermore, a rotating groove is provided on the inner wall of the plurality of limiting grooves, and the rotating rod is rotatably connected to the rotating groove.

[0016] By adopting the above technical solution, when the connecting disc rotates, the rotating rod and the rotating groove rotate relative to each other. During this process, the rotating groove limits the rotation rod, thereby reducing the probability of the rotating rod wobbling and improving the stability of the device.

[0017] Furthermore, multiple heat dissipation holes are provided through the inner wall of the rotating base.

[0018] By adopting the above technical solution, the heat dissipation holes reduce the probability of motor overheating and damage, thereby extending the service life of the device.

[0019] Furthermore, the end of the drive rod away from the rotating rod is provided with a rounded corner.

[0020] By adopting the above technical solution, the rounded corners reduce the probability of wear on the mounting rod when the drive rod approaches the mounting rod, thereby extending the service life of the device.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. In this application, when a worker needs to cut cardboard into a fan shape, the worker must place the cardboard into a stamping groove. Then, the worker must activate the stamping cylinder, causing the piston rod of the cylinder to move downwards, thereby driving the stamping cutter downwards to cut the cardboard into a fan shape. After cutting is complete, the worker must activate the drive device, causing the drive device to drive the worktable to rotate intermittently, thus aligning other stamping grooves with the stamping cutter. This process improves the worker's efficiency in cutting cardboard, thereby increasing the worker's overall work efficiency.

[0023] 2. In this application, when the operator needs to drive the worktable to rotate intermittently, the operator needs to start the motor, which in turn causes the motor output shaft to rotate. This causes the rotating rod to rotate under the action of the motor output shaft, which in turn causes the drive rod to rotate under the action of the rotating rod. This causes the side wall of the drive rod to gradually approach and eventually abut against the side wall of one of the mounting rods. This causes the mounting rod to rotate along the axis of the connecting plate under the action of the drive rod, which in turn causes the connecting plate to rotate under the action of the mounting rod, which in turn causes the connecting rod to rotate under the action of the connecting plate. This causes the worktable to rotate under the action of the connecting rod. During this process, the... Figure 3 and Figure 4 As shown, the axis of the rotating rod is parallel to the axis of the connecting rod. When the worktable rotates 90°, the driving rod and the mounting rod separate, thereby stopping the worktable from rotating. This makes the stamping groove and the stamping tool face each other. In this process, the efficiency of the workers in cutting cardboard is improved, thereby improving the workers' work efficiency.

[0024] 3. In this application, when the worktable rotates, the annular block rotates under the action of the worktable. During this process, the annular block limits the worktable, thereby reducing the probability of the worktable moving up and down, and thus improving the stability of the device.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-4 As shown in the illustration, this application discloses an automatic die-cutting device for double-sided coated paper cup-shaped cardboard, including a base 1, a rotating seat 11, a worktable 12, a support frame 14, a stamping cylinder 15, a stamping cutter 16, a control component 2, a drive component 3, and a limiting plate 5. The base 1 is a rectangular plate structure. The rotating seat 11 is a cylindrical structure with an open top and a vertical axis, and is fixedly mounted on the upper surface of the base 1. The worktable 12 is a cylindrical structure, with its axis coinciding with the axis of the rotating seat 11. The worktable 12 is rotatably mounted within the rotating seat 11, and its upper surface has a circumferential array of stamping grooves 13. The support frame 14 has an L-shaped cross-section and is fixedly mounted on the upper surface of the base 1. The stamping cylinder 15 is fixedly mounted on the upper surface of the support frame 14, with its piston rod having a vertical axis and penetrating through the support frame 14. The stamping cutter 16 is fixedly mounted at the end of the piston rod of the stamping cylinder 15 and is used to cut coated paperboard. The drive unit is located in the rotary seat 11 and is used to drive the worktable 12 to rotate intermittently. The drive unit includes a control component 2 and a drive component 3.

[0032] When workers need to cut cardboard into fan shapes, they place the cardboard into the stamping groove 13. Then, they activate the stamping cylinder 15, causing its piston rod to move downwards. This, in turn, moves the stamping cutter 16 downwards to cut the cardboard into a fan shape. After cutting, the workers activate the drive device, which then drives the worktable 12 to rotate intermittently, aligning the other stamping grooves 13 with the stamping cutter 16. This process improves the efficiency of cardboard cutting, thereby increasing the workers' overall work efficiency.

[0033] The control component 2 includes a connecting rod 21, a connecting plate 22, and mounting rods 23. The connecting rod 21 is a round rod structure, and its axis coincides with the axis of the worktable 12. The connecting rod 21 is fixedly mounted on the bottom surface of the worktable 12. The connecting plate 22 is fixedly mounted on the bottom surface of the connecting rod 21, and its axis coincides with the axis of the connecting rod 21. Multiple mounting rods 23 are arranged in a circumferential array on the bottom surface of the connecting plate 22, and their axes are vertical.

[0034] The drive assembly 3 includes a motor 31, a rotating rod 32, and a drive rod 33. The motor 31 is fixedly mounted on the inner bottom wall of the rotating base 11, and its output shaft axis is vertical. The rotating rod 32 is fixedly mounted on the end of the output shaft of the motor 31, and its axis coincides with the axis of the output shaft of the motor 31. The axis of the rotating rod 32 is parallel to the axis of the connecting rod 21. The drive rod 33 is fixedly mounted on the outer wall of the rotating rod 32, and the side wall of the drive rod 33 abuts against the side wall of the mounting rod 23.

[0035] When the operator needs to drive the worktable 12 to rotate intermittently, the operator needs to start the motor 31, which in turn causes the output shaft of the motor 31 to rotate. This causes the rotating rod 32 to rotate under the action of the output shaft of the motor 31, which in turn causes the drive rod 33 to rotate under the action of the rotating rod 32. This causes the side wall of the drive rod 33 to gradually approach and eventually abut against the side wall of one of the mounting rods 23, which in turn causes the mounting rod 23 to rotate along the axis of the connecting plate 22. This causes the connecting plate 22 to rotate under the action of the mounting rod 23, which in turn causes the connecting rod 21 to rotate under the action of the connecting plate 22, which in turn causes the worktable 12 to rotate under the action of the connecting rod 21. During this process, the... Figure 3 and Figure 4 As shown, the axis of the rotating rod 32 is parallel to the axis of the connecting rod 21. When the worktable 12 rotates 90°, the driving rod 33 separates from the mounting rod 23, thereby stopping the worktable 12 from rotating. This makes the stamping groove 13 face the stamping tool 16. In this process, the efficiency of the worker in cutting the cardboard is improved, thereby improving the worker's work efficiency.

[0036] To improve the stability of the device, an annular groove 4 is provided on the inner wall of the rotating base 11, and an annular block 41 is rotatably disposed in the annular groove 4. The annular block 41 is fixed to the worktable 12. When the worktable 12 rotates, the annular block 41 rotates under the action of the worktable 12. During this process, the annular block 41 limits the worktable 12, thereby reducing the probability of the worktable 12 moving up and down, thus improving the stability of the device.

[0037] The bottom surface of the connecting plate 22 is provided with multiple limiting grooves 51 arranged in a circular array. The limiting plate 5 is fixedly installed on the outer wall of the rotating rod 32, and its axis coincides with the axis of the rotating rod 32. The limiting plate 5 and the limiting groove 51 rotate relative to each other.

[0038] When the rotating rod 32 rotates, the limiting plate 5 rotates synchronously with the rotating rod 32. When the connecting plate 22 rotates, the limiting plate 5 and the limiting groove 51 rotate relative to each other, thereby reducing the probability of shaking when the connecting plate 22 rotates and improving the stability of rotation. Furthermore, due to... Figure 4 As shown, the limiting disk 5 is semi-circular, which reduces the probability of collision between the limiting disk 5 and the limiting groove 51, thereby further improving the stability of the device.

[0039] To improve the stability of the device, a rotating groove 6 is provided on the inner wall of multiple limiting grooves 51, and the rotating rod 32 is rotatably connected to the rotating groove 6. When the connecting plate 22 rotates, the rotating rod 32 and the rotating groove 6 rotate relative to each other. During this process, the rotating groove 6 limits the rotation of the rotating rod 32, thereby reducing the probability of the rotating rod 32 shaking and thus improving the stability of the device.

[0040] To extend the service life of the device, multiple heat dissipation holes are provided through the inner wall of the rotating base 11. These holes reduce the probability of the motor 31 overheating and being damaged, thereby extending the service life of the device.

[0041] To extend the service life of the device, a fillet 7 is provided at the end of the drive rod 33 away from the rotating rod 32. The fillet 7 reduces the probability of wear on the mounting rod 23 when the drive rod 33 approaches the mounting rod 23, thereby extending the service life of the device.

[0042] The operating principle of the automatic die-cutting device for double-sided coated paper cup-shaped cardboard in this embodiment is as follows: When the operator needs to cut the cardboard into a fan shape, the operator places the cardboard into the stamping groove 13. Then, the operator activates the stamping cylinder 15, causing the piston rod of the stamping cylinder 15 to move downwards, thereby driving the stamping cutter 16 downwards to cut the cardboard into a fan shape. After cutting, the operator activates the drive device, causing the drive device to drive the worktable 12 to rotate intermittently, so that the other stamping grooves 13 are aligned with the stamping cutter 16. This process improves the operator's efficiency in cutting the cardboard, thus increasing the operator's work efficiency.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
