Technical Field

[0001] This invention belongs to the field of packaging paper technology, specifically an automatic paper rolling packaging device. Background Technology

[0002] Currently, in the production and packaging of some flammable and explosive hollow medicinal cakes, the outer surface of the product is usually wrapped entirely manually with packaging paper rolls, which involves direct contact between people and the medicine. Given the flammable and explosive nature of the medicinal cakes, manual packaging poses significant safety hazards. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide an automatic paper roll packaging device.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] An automatic roll paper packaging device includes a base frame, a front support frame, a rear support frame, a product loading component, a product positioning component, a packaging paper folding component, a paper pushing component, a packaging paper packaging component, and an upper support frame.

[0006] The front support frame is located at the front side of the upper part of the base frame, and the rear support frame is located at the rear side of the upper part of the base frame.

[0007] The product loading component is mounted on the rear support frame and is used to load and move the product to or from the packaging paper component.

[0008] The upper support frame is located on the top surface of the front support frame away from the rear support frame. A sliding mounting bracket is slidably connected to the upper support frame. A cylinder A is also installed on the upper support frame. The driving end of the cylinder A is connected to the sliding mounting bracket and drives the sliding mounting bracket to move in the front-back direction. The axial center line of the driving end of the cylinder A is parallel to the horizontal plane.

[0009] The packaging paper folding assembly includes an elastic support structure and a packaging paper pressing head structure. The elastic support structure is disposed on the top surface of the front support frame, and the packaging paper pressing head structure is disposed on the sliding mounting frame. The packaging paper pressing head structure is used to press the packaging paper placed on the elastic support structure in its initial state and to fold the folded edges on both sides of the packaging paper in the length direction upward under the action of the elastic support structure.

[0010] The paper pushing component is disposed on the sliding mounting frame, and the paper pushing component is used to push the folded packaging paper from the elastic support structure to the packaging paper packaging component;

[0011] The packaging paper assembly is positioned between the front support frame and the rear support frame, and is used to wrap the folded packaging paper onto the outer periphery of the product that has been moved by the product loading assembly.

[0012] The product loading assembly includes a flip shaft, a flip shaft drive, and a product loading component. The flip shaft is rotatably mounted on the rear support frame. The flip shaft drive is fixedly mounted on the rear support frame. The drive end of the flip shaft drive is connected to one end of the flip shaft and drives the flip shaft to rotate. One end of the product loading component is fixed to the middle of the flip shaft. The other end of the product loading component is provided with an expansion sleeve that fits into the center hole of the product. The expansion sleeve passes through the center hole of the product and puts the product on the expansion sleeve.

[0013] The projection of the axial center line of the flipping shaft in the horizontal plane is perpendicular to the projection of the axial center line of the drive end of the cylinder A in the horizontal plane.

[0014] The flip shaft drive drives the flip shaft to rotate, which in turn drives the product loading component to rotate, thereby moving the product on the product loading component to or from the packaging paper assembly. After the product on the product loading component moves to the packaging paper assembly, the axial centerline of the product is parallel to the axial centerline of the drive end of the cylinder A.

[0015] The product positioning component includes a medicine cake positioning shaft and a cylinder B. The cylinder body of the cylinder B is mounted on a cylinder mounting plate. The cylinder mounting plate is connected to the sliding mounting frame through several support columns. One end of the medicine cake positioning shaft is connected to the drive end of the cylinder B, and the other end of the medicine cake positioning shaft passes through the sliding mounting frame.

[0016] The axial centerline of the drive end of cylinder B, the axial centerline of the medicated cake positioning shaft, and the axial centerlines of each support column are all parallel to the axial centerline of the drive end of cylinder A.

[0017] After the product on the product loading component moves to the packaging paper packaging assembly, the driving end of the cylinder B extends, causing the other end of the medicine cake positioning shaft to abut against the product from the product's axial direction and axially limit the product.

[0018] The paper pushing assembly includes a cylinder C, a push plate, and a guide shaft A. The cylinder C is mounted on the sliding mounting frame, and the driving end of the cylinder C is connected to the push plate. The push plate is located on the side of the sliding mounting frame closer to the elastic support structure. One end of the guide shaft A is connected to the push plate, and the other end passes through the sliding mounting frame. The axial center line of the driving end of the cylinder C and the axial center line of the guide shaft A are both parallel to the axial center line of the driving end of the cylinder A.

[0019] The packaging paper pressing head structure includes a cylinder D and a packaging paper pressing head. The cylinder D is mounted on the sliding mounting frame. The driving end of the cylinder D faces downward and is connected to the packaging paper pressing head. The axial center line of the driving end of the cylinder D is perpendicular to the horizontal plane.

[0020] The elastic support structure includes a folding support plate, guide shafts B, springs A, a folding roller mounting frame, and folding rollers. The folding support plate is located above the front support frame and is used to place the packaging paper in its initial state to be folded. The bottom surface of the folding support plate is connected to the upper ends of several guide shafts B. The lower end of each guide shaft B passes through the top surface of the front support frame. A spring A is fitted onto each guide shaft B between the top surface of the front support frame and the bottom surface of the folding support plate. Each of the front support frames on the front and rear sides is provided with a folding roller mounting frame. Each folding roller mounting frame has a folding roller rotatably mounted at its top. The folding rollers on the front folding roller mounting frames are located on the front side of the folding support plate, and the folding rollers on the rear folding roller mounting frames are located on the rear side of the folding support plate. The projection of the axial center line of each folding roller in the horizontal plane is perpendicular to the projection of the axial center line of the drive end of cylinder A in the horizontal plane.

[0021] The sliding mounting bracket drives the cylinder D connected to the packaging paper pressure head to move back and forth. When the packaging paper pressure head moves directly above the folding support plate, the driving end of the cylinder D extends, causing the packaging paper pressure head to press the packaging paper on the folding support plate and the folding support plate downward. The spring A is compressed, and the folding support plate is pressed down below each of the folding rollers. The folded edges on both sides of the packaging paper in the length direction are folded upward by the folding rollers located on the front and rear sides of the folding support plate. The driving end of the cylinder D retracts, causing the packaging paper pressure head to rise again, and the folding support plate returns to its initial height position under the action of the spring A.

[0022] The packaging paper assembly includes a main packaging structure, a packaging paper end limiting structure, and a rolling sealing structure.

[0023] The main packaging structure includes a lifting frame, a U-shaped elastic baffle, roller A, and cylinder E. Cylinder E is mounted on a base frame between the front and rear support frames. The drive end of cylinder E faces upwards and is connected to the bottom of the lifting frame. The axial centerline of the drive end of cylinder E is perpendicular to the horizontal plane. A limiting block is provided on the top surface of the lifting frame to block the folded packaging paper pushed by the paper pushing assembly. A product passage opening is provided in the center of the top surface of the lifting frame. The U-shaped elastic baffle is installed inside the lifting frame and has an upward-facing U-shaped opening. The U-shaped opening of the U-shaped elastic baffle corresponds vertically to the product passage opening. Rollers A are respectively provided at both ends of the opening, and the axial center line of each roller A is parallel to the axial center line of the driving end of the cylinder A. After the product on the product loading component moves to the packaging paper packaging component, the product is located directly above the product passage and the U-shaped opening of the U-shaped elastic baffle. The driving end of the cylinder E extends, thereby driving the lifting frame to rise. The packaging paper on the lifting frame is pressed by the product. The packaging paper and the product fall together through the product passage into the inner bottom of the U-shaped elastic baffle. The inner bottom of the U-shaped elastic baffle holds the packaging paper and makes the packaging paper surround the downward-facing outer peripheral surface of the product. The two ends of the packaging paper in the length direction are pressed upward and folded by the rollers A at both ends of the U-shaped opening of the U-shaped elastic baffle to realize the initial packaging operation.

[0024] The end-limiting structure of the packaging paper includes a cylinder F and rollers B. There are two cylinders F, which are located directly above the two ends of the packaging paper blocked by the limiting blocks along its length. The cylinder body of each cylinder F is connected to the rear support frame. The driving end of each cylinder F faces downward and is connected to the rollers B. The axial center line of the driving end of each cylinder F is perpendicular to the horizontal plane, and the axial center line of each roller B is parallel to the axial center line of the driving end of the cylinder A. When the driving end of each cylinder F extends, each roller B abuts against the packaging paper from above.

[0025] The rolling sealing structure includes cylinders G and rollers C. Two cylinders F are provided and are respectively located on both sides of the product on the product loading component after it has moved to the packaging paper packaging assembly. The cylinder body of each cylinder G is connected to the rear support frame. The driving end of each cylinder G faces the side closer to the product and is connected to the roller C. The axial center line of each roller C is parallel to the axial center line of the driving end of cylinder A. After the driving end of cylinder E extends, when the driving end of each cylinder G extends, each roller C moves to the top of the product and rolls along the upward-facing outer peripheral surface of the product, thereby pressing the two ends of the packaging paper located outside the product along its length onto the upward-facing outer peripheral surface of the product, thus realizing the rolling sealing operation.

[0026] Each roller C is connected to the drive end of the corresponding cylinder G via a swing connector. Each swing connector includes a fixed hinge frame and a swing hinge frame. The fixed hinge frame is fixedly installed on the drive end of the corresponding cylinder G. The middle part of the swing hinge frame is hinged to the fixed hinge frame of the same swing connector via a hinge shaft. The axial center line of the hinge shaft is parallel to the axial center line of the drive end of the cylinder A. The end of the swing hinge frame closer to the product is rotatably mounted with the corresponding roller C. The end of the swing hinge frame away from the product is provided with a limiting shaft. The fixed hinge frame is provided with a limiting ear at a position corresponding to the limiting shaft on the fixed hinge frame of the same swing connector. The limiting ear has a limiting elongated hole for the corresponding limiting shaft to pass through.

[0027] The present invention also includes an adhesive tape assembly, which includes a tape machine, a swing drive, a pneumatic gripper, a cylinder H, and a tape pressure head. The tape machine is mounted on the base frame, with the tape output end of the tape machine close to one end of the lifting frame. The swing drive is fixedly mounted on the rear support frame, and the pneumatic gripper is mounted on the drive end of the swing drive. The cylinder H is mounted inside one end of the lifting frame, with the drive end of the cylinder H facing upward and connected to the tape pressure head. The axial centerline of the drive end of the cylinder H is perpendicular to the horizontal plane. A tape pressure head passage is provided on the top surface of the lifting frame, and the tape pressure head is located below the drive end of an adjacent cylinder F.

[0028] The pneumatic gripper is initially positioned near the tape output end of the tape machine and is used to grip tape from the tape output end. After the pneumatic gripper grips the tape, the driving end of the swing drive drives the pneumatic gripper to rotate to a position above the tape pressure head and below one end of the packaging paper along its length. The driving end of the cylinder F extends and moves the tape pressure head upward through the tape pressure head passage, pressing one end of the tape gripped by the pneumatic gripper onto the lower surface of one end of the packaging paper along its length. After one end of the tape is pressed onto the packaging paper, the driving end of the cylinder F retracts to its original position, and the driving end of the swing drive drives the pneumatic gripper to rotate back to the side near the tape output end of the tape machine. During the rolling and closing operation, the tape originally pressed onto the lower surface of one end of the packaging paper along its length is bonded to the other end of the packaging paper along its length by the pressing action of the roller C located near the tape machine.

[0029] The invention also includes a feeding assembly for moving the packaging paper in its initial state to the elastic support structure of the packaging paper folding assembly;

[0030] The feeding assembly includes a material trough, a lifting electric cylinder, a lifting bracket, cylinder I, a suction cup translation seat, an extension adapter plate, a suction cup mounting plate, a guide shaft C, a spring B, and a vacuum suction cup. The material trough is set on the base frame and is used to stack the packaging paper in its initial state. The lifting electric cylinder is installed on the base frame, with its drive end facing upwards and connected to the lifting bracket. The axial centerline of the drive end of the lifting electric cylinder is perpendicular to the horizontal plane. The cylinder body of cylinder I is installed on the lifting bracket, and the axial centerline of the drive end of cylinder I is parallel to the horizontal plane. The projection of the axial centerline of the drive end of cylinder I onto the horizontal plane is parallel to the drive end of cylinder A. The projections of the axial center lines of the ends onto the horizontal plane are perpendicular to each other. One end of the suction cup translation seat is connected to the driving end of the cylinder I, and the other end of the suction cup translation seat is connected to the extension adapter plate. The suction cup mounting plate is located below the extension adapter plate. The top surface of the suction cup mounting plate is provided with the lower ends of several guide shafts C. The upper ends of each guide shaft C pass through the extension adapter plate. A spring B is provided on the outer side of each guide shaft C between the extension adapter plate and the suction cup mounting plate. The upper and lower ends of each spring B are connected to the extension adapter plate and the suction cup mounting plate, respectively. Several vacuum suction cups are provided on the lower surface of the suction cup mounting plate.

[0031] A material trough support frame is fixedly installed on the basic frame, and the material trough is slidably connected to the material trough support frame. A handle is provided on the material trough.

[0032] The advantages and positive effects of this invention are as follows:

[0033] This invention, through the coordinated arrangement of a basic frame, a front support frame, a rear support frame, a product loading component, a product positioning component, a packaging paper folding component, a paper pushing component, a packaging paper packaging component, and an upper support frame, can automatically wrap the packaging paper roll around the outer periphery of the medicinal cake product, realizing the automated operation of this process.

[0048] 001 represents the initial state of the packaging paper, 0011 represents the folded edge, 002 represents the finished folded packaging paper, and 003 represents the product. Detailed Implementation

[0049] The following is in conjunction with the appendix Figure 1-13 The present invention will be described in further detail below.

[0050] An automatic paper roll packaging device, such as Figure 1-13 As shown, this embodiment includes a base frame 1, a front support frame 2, a rear support frame 3, a product loading assembly, a product positioning assembly, a packaging paper folding assembly, a paper pushing assembly, a packaging paper packaging assembly, and an upper support frame 4. Figure 2 As shown, the packaging paper 001 is in the initial state of packaging the product 003 applicable in this embodiment. The shape of the packaging paper 001 is the same as that of the packaging paper applicable in the prior art, and it has folded edges 0011 on both sides in the length direction. After the outer periphery of the product 003 is covered by the folded packaging paper 002, the folded edges 0011 are used for subsequent packaging of the end face of the product 003.

[0051] The front support frame 2 is located at the front of the upper part of the base frame 1, and the rear support frame 3 is located at the rear of the upper part of the base frame 1.

[0052] The product loading assembly is mounted on the rear support frame 3 and is used to load and move the product 003 to or from the packaging paper assembly.

[0053] The upper support frame 4 is positioned on the top surface of the front support frame 2, away from the rear support frame 3. A sliding mounting bracket 5 is slidably connected to the upper support frame 4 via a guide rail slider. A cylinder A6 is also mounted on the upper support frame 4 via a cylinder mounting bracket A 55. The driving end of the cylinder A6 is connected to the sliding mounting bracket 5 and drives the sliding mounting bracket 5 to move in the front-to-back direction. The axial centerline of the driving end of the cylinder A6 is parallel to the horizontal plane. In this embodiment, the cylinder A6 is a commercially available product, and its operation is controlled by an external controller.

[0054] The packaging paper folding assembly includes an elastic support structure and a packaging paper pressing head structure. The elastic support structure is set on the top surface of the front support frame 2, and the packaging paper pressing head structure is set on the sliding mounting frame 5. The packaging paper pressing head structure is used to press the packaging paper 001 in its initial state placed on the elastic support structure and to fold the folded edges 0011 on both sides of the packaging paper in the length direction upward under the action of the elastic support structure.

[0055] The paper pushing assembly is mounted on the sliding mounting frame 5. The paper pushing assembly is used to push the folded packaging paper 002 from the elastic support structure to the packaging paper packaging assembly.

[0056] The packaging paper assembly is positioned between the front support frame 2 and the rear support frame 3, and is used to wrap the folded packaging paper 002 onto the outer periphery of the product 003 that has been moved by the product loading assembly.

[0057] Specifically, such as Figure 4 and Figure 5 As shown, in this embodiment, the product loading assembly includes a tilting shaft 7, a tilting shaft drive 8, and a product loading component 9. The tilting shaft 7 is rotatably mounted on the rear support frame 3, and the tilting shaft drive 8 is fixedly mounted on the rear support frame 3. The drive end of the tilting shaft drive 8 is connected to one end of the tilting shaft 7 and drives the tilting shaft 7 to rotate. One end of the product loading component 9 is fixed to the middle of the tilting shaft 7, and the other end of the product loading component 9 is provided with an expansion sleeve that fits into the center hole of the product 003. The expansion sleeve passes through the center hole of the product 003 and makes the product 003 fit on the expansion sleeve. The expansion sleeve setting structure adopts existing technology. In this embodiment, the mounting structure of the tilting shaft 7 adopts existing technology. For example, the tilting shaft 7 can be mounted on the rear support frame 3 by a bearing seat with a deep groove ball bearing. In this embodiment, the tilting shaft drive 8 is a commercially available motor, and its operation is controlled by an external controller.

[0058] The projection of the axial center line of the flipping shaft 7 onto the horizontal plane is perpendicular to the projection of the axial center line of the drive end of cylinder A 6 onto the horizontal plane.

[0059] The flip shaft drive 8 drives the flip shaft 7 to rotate, which in turn drives the product loading component 9 to rotate, thereby moving the product 003 on the product loading component 9 to or from the packaging paper packaging component; after the product on the product loading component 9 moves to the packaging paper packaging component, the axial center line of the product 003 is parallel to the axial center line of the drive end of the cylinder A 6.

[0060] Specifically, such as Figure 1 and Figure 6 As shown, in this embodiment, the product positioning component includes a medicine cake positioning shaft 10 and a cylinder B11. The cylinder body of the cylinder B11 is mounted on a cylinder mounting plate 12, which is connected to a sliding mounting frame 5 via four support columns 13. One end of the medicine cake positioning shaft 10 is connected to the drive end of the cylinder B11, and the other end of the medicine cake positioning shaft 10 passes through the sliding mounting frame 5. In this embodiment, the cylinder B11 is a commercially available product, and its operation is controlled by an external controller.

[0061] The axial centerline of the drive end of cylinder B11, the axial centerline of the cadmium positioning shaft 10, and the axial centerlines of each support column 13 are all parallel to the axial centerline of the drive end of cylinder A6.

[0062] After product 003 on product loading component 9 moves to packaging paper packaging component, the drive end of cylinder B11 extends, so that the other end of medicine cake positioning shaft 10 abuts against product 003 from the axial direction of product 003 and limits product 003 axially.

[0063] Specifically, such as Figure 1 and Figure 6 As shown, in this embodiment, the paper pushing assembly includes a cylinder C14, a push plate 15, and a guide shaft A16. The cylinder C14 is mounted on the sliding mounting frame 5, and its drive end is connected to the push plate 15. The push plate 15 is located on the side of the sliding mounting frame 5 closest to the elastic support structure. One end of the guide shaft A16 is connected to the push plate 15, and the other end passes through the sliding mounting frame 5. The axial centerline of both the drive end of the cylinder C14 and the axial centerline of the guide shaft A16 are parallel to the axial centerline of the drive end of the cylinder A16. In this embodiment, the cylinder C14 is a commercially available product, and its operation is controlled by an external controller. The guide shaft A16 guides the movement of the push plate 15 driven by the cylinder C14.

[0064] Specifically, such as Figure 1 and Figure 6As shown, the packaging paper pressing head structure in this embodiment includes a cylinder D17 and a packaging paper pressing head 18. The cylinder D17 is mounted on the sliding mounting bracket 5 via a cylinder mounting bracket B 56. The driving end of the cylinder D17 faces downward and is connected to the packaging paper pressing head 18. The axial center line of the driving end of the cylinder D17 is perpendicular to the horizontal plane. In this embodiment, the cylinder D17 is a commercially available product, and its operation is controlled by an external controller.

[0065] like Figure 1 , Figure 3 and Figure 6 As shown, the elastic support structure includes a folding support plate 19, guide shafts B 20, springs A 21, a folding roller mounting frame 22, and a folding roller 23. The folding support plate 19 is located above the front support frame 2 and is used to place the packaging paper 001 in its initial state to be folded. The bottom surface of the folding support plate 19 is connected to the upper ends of several guide shafts B 20. The lower end of each guide shaft B 20 passes through the top surface of the front support frame 2. A spring A is sleeved on each guide shaft B 20 between the top surface of the front support frame 2 and the bottom surface of the folding support plate 19. 21. A folding roller mounting frame 22 is respectively provided on the top surface of the front support frame 2 on both the front and rear sides of the folding support plate 19. A folding roller 23 is rotatably mounted on the top of each folding roller mounting frame 22. The folding roller 23 on the front folding roller mounting frame 22 is located on the front side of the folding support plate 19, and the folding roller 23 on the rear folding roller mounting frame 22 is located on the rear side of the folding support plate 19. The projection of the axial center line of each folding roller 23 in the horizontal plane is perpendicular to the projection of the axial center line of the driving end of the cylinder A 6 in the horizontal plane.

[0066] The sliding mounting bracket 5 drives the cylinder D17, which is connected to the packaging paper pressure head 18, to move back and forth. When the packaging paper pressure head 18 moves directly above the folding support plate 19, the driving end of the cylinder D17 extends, causing the packaging paper pressure head 18 to press the packaging paper on the folding support plate 19 and the folding support plate 19 to move downward. The spring A 21 is compressed, and the folding support plate 19 is pressed down to a position lower than each folding roller 23. The folded edges 0011 on both sides of the packaging paper in the length direction are folded upward by the folding rollers 23 located on the front and rear sides of the folding support plate 19. The driving end of the cylinder D17 retracts, causing the packaging paper pressure head 18 to rise again, and the folding support plate 19 returns to its initial height position under the action of the spring A21.

[0067] Specifically, such as Figure 8-12 As shown, in this embodiment, the packaging paper packaging assembly includes a main packaging structure, a packaging paper end limiting structure, and a rolling sealing structure.

[0068] The main packaging structure includes a lifting frame 24, a U-shaped elastic baffle 25, rollers A 26, and a cylinder E 27. Cylinder E 27 is mounted on the base frame 1 between the front support frame 2 and the rear support frame 3. The drive end of cylinder E 27 faces upwards and is connected to the bottom of the lifting frame 24. The axial centerline of the drive end of cylinder E 27 is perpendicular to the horizontal plane. A limiting block 28 is provided on the top surface of the lifting frame 24 to block the folded packaging paper 002 pushed by the paper pushing assembly. A product passage opening is provided in the center of the top surface of the lifting frame 24. The U-shaped elastic baffle 25 is installed inside the lifting frame 24. The U-shaped elastic baffle 25 has an upward-facing U-shaped opening, which corresponds vertically to the product passage opening. Rollers A 26 are provided at both ends of the U-shaped opening of the U-shaped elastic baffle 25. The axial centerlines of each roller A 26 are parallel to the cylinder A. The axial centerline of the drive end of 6. After the product 003 on the product loading component 9 moves to the packaging paper assembly, the product 003 is located directly above the product passage and the U-shaped opening of the U-shaped elastic baffle 25. In this embodiment, the cylinder E 27 is a commercially available product, and its operation is controlled by an external controller. The drive end of the cylinder C14 extends and drives the push plate 15 to push the folded packaging paper 002 from the folding support plate 19 to the top surface of the lifting frame 24. The folded packaging paper 002 is blocked by the limiting block 28. The drive end of cylinder E 27 extends, thereby driving the lifting frame 24 to rise. The folded packaging paper 002 on the lifting frame 24 is pressed by the product 003. The packaging paper and the product 003 fall together through the product passage into the inner bottom of the U-shaped elastic baffle 25. The inner bottom of the U-shaped elastic baffle 25 holds the packaging paper and makes it surround the downward-facing outer peripheral surface of the product 003. The two ends of the packaging paper in the length direction are pressed upward and folded by the rollers A 26 at both ends of the U-shaped opening of the U-shaped elastic baffle 25, realizing the initial packaging operation. In this embodiment, the lifting frame 24 and the rear support frame 3 are connected by a guide rail slider.

[0069] The end-limiting structure of the packaging paper includes cylinders F29 and rollers B30. Two cylinders F29 are provided, located directly above the two ends of the packaging paper along its length, which are blocked by the limiting blocks 28. The cylinder body of each cylinder F29 is connected to the rear support frame 3. The drive end of each cylinder F29 faces downwards and is connected to rollers B30. The axial centerline of the drive end of each cylinder F29 is perpendicular to the horizontal plane, and the axial centerline of each roller B30 is parallel to the axial centerline of the drive end of cylinder A6. In this embodiment, the cylinders F29 are commercially available and their operation is controlled by an external controller; the mounting structure of the cylinders F29 is also existing technology. When the drive end of each cylinder F29 extends, each roller B30 abuts against the packaging paper from above, preventing the two ends of the packaging paper along its length from curling upwards on the downward-facing outer periphery of the product 003, thus affecting the packaging effect. The roller B 30 is designed so that when the packaging paper is pressed by product 003, both ends of the packaging paper can disengage from the drive end of cylinder F 29 along the top surface of lifting frame 24.

[0070] The rolling and closing structure includes cylinders G 31 and rollers C 32. Two cylinders F 29 are provided, respectively positioned on both sides of the product 003 on the product loading component 9 after it has moved to the packaging paper assembly. The cylinder body of each cylinder G 31 is connected to the rear support frame 3. The drive end of each cylinder G 31 faces the side closest to the product and is connected to a roller C 32. The axial centerline of the drive end of each cylinder G 31 is parallel to the horizontal plane, and the axial centerline of each roller C 32 is parallel to the axial centerline of the drive end of cylinder A 6. In this embodiment, cylinder G 31 is a commercially available product, and its operation is controlled by an external controller; the mounting structure of cylinder G 31 is also existing technology. After the drive end of cylinder E 27 extends, when the drive end of each cylinder G 31 extends, each roller C 32 moves above product 003 and rolls along the upward-facing outer circumferential surface of product 003, thereby pressing the two ends of the packaging paper located outside product 003 along its length onto the upward-facing outer circumferential surface of product 003, realizing the rolling and sealing operation. Before the drive end of cylinder E 27 extends and drives the lifting frame 24 to rise, the drive ends of each cylinder F 29 extend to their positions first; when the drive end of cylinder E 27 extends and drives the lifting frame 24 to rise, cylinder F 29 connected to roller B 30 is pushed back by the lifting frame 24; when the lifting frame 24 rises to its highest position, the drive end of control cylinder F 29 retracts to its initial position, and then the drive ends of each cylinder G 31 extend to avoid interference.

[0071] Each roller C 32 is connected to the drive end of the corresponding cylinder G 31 via a swing connector. Each swing connector includes a fixed hinge frame 34 and a swing hinge frame 35. The fixed hinge frame 34 is fixedly installed on the drive end of the corresponding cylinder G 31. The middle part of the swing hinge frame 35 is hinged to the fixed hinge frame 34 of the same swing connector via a hinge shaft 36. The axial center line of the hinge shaft 36 is parallel to the axial center line of the drive end of the cylinder A 6. The corresponding roller C 32 is rotatably installed on the end of the swing hinge frame 35 closest to the product 002. A limiting shaft 37 is provided on the end of the swing hinge frame 35 furthest from the product 003. A limiting ear is provided on the fixed hinge frame 34 at a position corresponding to the limiting shaft 37 on the fixed hinge frame 34 of the same swing connector. The limiting ear has a limiting elongated hole for the corresponding limiting shaft 37 to pass through. By using the swing connector, the roller C32 can move more accurately and smoothly along the upward-facing arc surface of product 003, ensuring that the packaging paper is accurately rolled on the upward-facing outer circumferential surface of product 003.

[0072] like Figure 8-12 As shown, the automatic paper roll packaging device in this embodiment also includes an adhesive tape assembly, which includes a tape machine 38, a swing drive 39, a pneumatic gripper 40, a cylinder H 41, and a tape pressure head 42.

The swing drive 39 is fixedly mounted on the rear support frame 3. The pneumatic gripper 40 is mounted on the drive end of the swing drive 39. The cylinder H 41 is mounted inside one end of the lifting frame 24. The drive end of the cylinder H 41 faces upward and is connected to the tape pressure head 42. The axial centerline of the drive end of the cylinder H 41 is perpendicular to the horizontal plane. A tape pressure head passage is provided on the top surface of the lifting frame 24. The tape pressure head 42 is located below the drive end of an adjacent cylinder F 29. In this embodiment, the tape machine 38, the swing drive 39, the pneumatic gripper 40, and the cylinder H 41 are all commercially available products, and their actions are controlled by an external controller. The swing drive 39 is a commercially available swing cylinder, which is mounted on the rear support frame 3 via the swing cylinder mounting seat 33.

[0073] The pneumatic gripper 40 is initially positioned near the tape output end of the tape machine 38 and is used to grip the tape from the tape output end of the tape machine 38. After the pneumatic gripper 40 grips the tape, the driving end of the swing drive 39 drives the pneumatic gripper 40 to rotate to a position above the tape pressure head 42 and below one end of the packaging paper along its length. The driving end of the cylinder F 29 extends, causing the tape pressure head 42 to move upward through the tape pressure head passage and press one end of the tape gripped by the pneumatic gripper 40 onto the lower surface of one end of the packaging paper along its length. After one end of the tape is pressed onto the packaging paper, the driving end of the cylinder F 29 retracts to its original position, and the driving end of the swing drive 39 drives the pneumatic gripper 40 to rotate back to the side near the tape output end of the tape machine 38. During the rolling and closing operation, the tape originally pressed onto the lower surface of one end of the packaging paper along its length is rolled onto the roller C located near the side of the tape machine 38. Under the pressure of 32, it is bonded to the other end of the packaging paper along its length.

In this embodiment, the lifting electric cylinder 45, the cylinder I 47, and each vacuum suction cup 53 are commercially available products and their operation is controlled by an external controller. The material trough 44 is mounted on the base frame 1 and is used to stack the packaging paper 001 in its initial state. The lifting cylinder 45 is installed on the base frame 1. The drive end of the lifting cylinder 45 faces upward and is connected to the lifting bracket 46. The axial center line of the drive end of the lifting cylinder 45 is perpendicular to the horizontal plane. The cylinder body of cylinder I 47 is installed on the lifting bracket 46. The axial center line of the drive end of cylinder I 47 is parallel to the horizontal plane. The projection of the axial center line of the drive end of cylinder I 47 in the horizontal plane is perpendicular to the projection of the axial center line of the drive end of cylinder A 6 in the horizontal plane. One end of the suction cup translation seat 48 is connected to the drive end of cylinder I 47, and the other end of the suction cup translation seat 48 is connected to the extension adapter plate 49. The suction cup mounting plate 50 is located below the extension adapter plate 49. The top surface of the suction cup mounting plate 50 is provided with the lower ends of several guide shafts C 51. The upper ends of each guide shaft C 51 pass through the extension adapter plate 49. Each guide shaft C 51 between the extension adapter plate 49 and the suction cup mounting plate 50... Springs B 52 are provided on the outer side of each plate 51. The upper and lower ends of each spring B 52 are connected to the extension adapter plate 49 and the suction cup mounting plate 50, respectively. Several vacuum suction cups 53 are provided on the lower surface of the suction cup mounting plate 50. In this embodiment, the lifting bracket 46 is also connected to the base frame 1 through a guide rail slider. The vacuum suction cups 53 are used to adsorb the packaging paper 001 in its initial state. The guide shaft C 51 and the springs B 52 between the extension adapter plate 49 and the suction cup mounting plate 50 play a buffering role when the vacuum suction cups 53 adsorb the packaging paper 001 in its initial state after the suction cup mounting plate 50 is lowered. The lifting electric cylinder 45, the lifting bracket 46, the cylinder I 47, the suction cup translation seat 48, and the extension adapter plate 49 are arranged to adjust the position of the suction cup mounting plate 50, thereby transferring the packaging paper.

[0075] In this embodiment, a material trough support frame 54 is fixedly installed on the base frame 1.

The handle 55 can be pulled to move the material trough 44 for easy replenishment of packaging paper.

[0076] Working principle:

[0077] When the initial packaging paper 001 enters the feed trough 44, it is transported to the folding support plate 19 by the feeding component. After the feeding component returns to its original position, the packaging paper is folded by the combined action of the elastic support structure of the packaging paper folding component and the packaging paper pressing head structure. Then, the folded packaging paper 002 is pushed to the top surface of the lifting frame 24 by the paper pushing component, and the paper pushing component retracts. The adhesive tape component presses a fixed length of adhesive tape onto the lower surface of one end of the packaging paper along its length. At this time, the product loading component moves the product 003 to directly above the product passage and the U-shaped opening of the U-shaped elastic baffle 25. Afterward, the drive ends of each cylinder F 29 extend into place, causing each roller B 30 cylinders E27 extend from above, pressing against the packaging paper. The inner bottom of the U-shaped elastic baffle 25 presses against the packaging paper, causing it to surround the downward-facing outer periphery of product 003. The two ends of the packaging paper along its length are pressed upwards and folded by rollers A26 at the U-shaped openings of the U-shaped elastic baffle 25, completing the initial packaging operation. When the driving end of cylinder E27 extends, driving the lifting frame 24 upwards, cylinders F29 connected to rollers B30 are pushed back by the lifting frame 24. After the lifting frame 24 reaches its highest position, the driving ends of cylinders F29 are retracted to their initial positions. Then, the driving ends of cylinders G31 extend, and rollers C... 32 moves to above product 003 and rolls along the upward-facing outer periphery of product 003, thereby pressing the two ends of the packaging paper located on the outer surface of product 003 along the length direction onto the upward-facing outer periphery of product 003, realizing the rolling and sealing operation, and completing the process of wrapping the packaging paper roll around the outer periphery of product 003.
