Description

Technical Field

[0001] This utility model relates to the field of palletizing machine technology, and in particular to a palletizing machine for paper products. Background Technology

[0002] A palletizer for paper products is an automated device that neatly stacks paper products (such as cartons, boxes, and molded pulp products) onto pallets or designated locations in a specific arrangement. It improves the efficiency of paper product handling and storage, reduces manual labor intensity, and has the following structure:

[0003] 1. Base: The guide rails on the base are used for the horizontal movement of the base;

[0004] 2. Movable base: Slides on the base, which is equipped with slide rails for the gripping mechanism to move up and down.

[0005] 3. Gripping Mechanism: The key component of the palletizer that directly contacts the paper products and completes the gripping action. The suction cup gripping mechanism mainly consists of a vacuum pump, suction cup, air pipe, etc. The vacuum pump generates negative pressure, causing the suction cup to adhere to the surface of the paper products, thereby achieving gripping.

[0006] During the use of paper product palletizers, the guide rail on the base is a key component for the sliding of the moving base. The palletizing operation environment is often quite complex, and impurities such as paper scraps and dust will be generated. If impurities enter the base guide rail area and adhere to the outside of the guide rail, the frictional resistance between the guide rail and the moving base will increase, resulting in a decrease in the smoothness of the sliding of the moving base, and thus reducing the accuracy of paper product palletizing. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a palletizing machine for paper products, which solves the technical problem that impurities enter the base guide rail area and adhere to the outside of the guide rail, increasing the frictional resistance between the guide rail and the moving base, resulting in a decrease in the smoothness of sliding of the moving base, and thus reducing the accuracy of paper product palletizing.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A palletizer for paper products includes a base, a movable base slidably connected to the outside of the base, and protective mechanisms at both ends of the base. Each protective mechanism includes a fixed frame and a protective cloth. The fixed frame is located outside the base, one end of the protective cloth is located outside the movable base, and the other end is located outside the fixed frame. Two support shafts are provided between the two fixed frames, and the two ends of the two protective cloths are slidably connected to the outside of the two support shafts, respectively.

[0010] Preferably, each protective fabric has a support frame one and a support frame two fixedly installed at both ends, and the support frame one and the support frame two are slidably connected to the outside of the support shaft.

[0011] Preferred configuration: The movable base has two bolts 1 slidably connected to one side of each support frame 1, and each bolt 1 has a nut 1 threadedly connected to the outside of the bolt 1. The support frame 1 is slidably connected to the outside of the bolt 1. The fixed frame has two bolts 2 slidably connected to the outside of the fixed frame, and each bolt 2 has a nut 2 threadedly connected to the outside of the bolt 2. The support frame 2 is slidably connected to the outside of the bolt 2. This is the structure for assembling and disassembling the protective cloth.

[0012] Preferred configuration: Each fixed frame has round holes at both ends, and each protective cloth has mounting holes at both ends. The protective cloth is slidably connected to the outside of the support shaft through the mounting holes. The two ends of the support shaft are slidably connected to the inside of the two round holes. Each support shaft is fixedly installed with a screw, and each screw is threaded with a nut for preventing the support shaft from moving.

[0013] Preferably, the base has a storage slot on one side corresponding to each fixed frame, the fixed frame is slidably connected to the inside of the storage slot, and the base has threaded holes at both ends corresponding to each storage slot, with a threaded rod threadedly connected inside each threaded hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the movable base slides outside the base, one end of the protective cloth is set outside the movable base and the other end is set outside the fixed frame. The sliding of the movable base will drive the protective cloth to slide on the support shaft, thereby realizing the extension and contraction of the protective cloth. During the paper product stacking process, the movement of the movable base will cause the two protective cloths to extend or contract, protecting the guide rail area on the base and preventing impurities from entering the guide rail area on the base. This reduces the problem of increased frictional resistance between the guide rail and the movable base due to impurities, thereby ensuring the smooth sliding of the movable base and thus ensuring the accuracy of paper product stacking.

[0016] Second, the threaded rod and threaded hole facilitate the stability of the fixed frame in the storage state and during use. When the palletizer is transferred, it pushes the fixed frame so that one end of the fixed frame is attached to the base. At this time, the other end of the fixed frame slides inside the storage slot, thereby reducing the space occupied by the palletizer during transfer and reducing the difficulty of transfer.

[0023] This application provides a palletizing machine for paper products, which effectively solves the technical problem that impurities enter the base guide rail area and adhere to the outside of the guide rail, increasing the frictional resistance between the guide rail and the moving base, resulting in a decrease in the smoothness of sliding of the moving base, and thus reducing the accuracy of paper product palletizing.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that impurities enter the base guide rail area and adhere to the outside of the guide rail, increasing the frictional resistance between the guide rail and the moving base, resulting in a decrease in the smoothness of sliding of the moving base, and thus reducing the accuracy of paper product stacking. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a palletizing machine for paper products, including a base 1, a movable base 2 slidably connected to the outside of the base 1, and protective mechanisms provided at both ends of the base 1. Each protective mechanism includes a fixed frame 3 and a protective cloth 4. The fixed frame 3 is located outside the base 1, and one end of the protective cloth 4 is located outside the movable base 2, and the other end is located outside the fixed frame 3. Two support shafts 5 are provided between the two fixed frames 3, and the two ends of the two protective cloths 4 are slidably connected to the outside of the two support shafts 5 respectively.

[0027] The protective cloth 4 extends and retracts when the movable base 2 slides, protecting the guide rail area on the base 1 and preventing paper scraps, dust and other impurities generated during the paper product stacking process from entering the guide rail and affecting the normal sliding of the movable base 2. The fixed frame 3 is a distance away from the base 1 to provide space for the protective cloth 4 to retract. The support shaft 5 ensures that the protective cloth 4 will not shift during the extension and retraction process, and at the same time prevents the protective cloth 4 from falling down during the retraction process.

[0028] Each protective cloth 4 has a support frame 6 and a support frame 7 fixedly installed at both ends. Both support frames 6 and 7 are concave and are slidably connected to the outside of the support shaft 5.

[0029] Each side of the movable base 2 corresponding to each support frame 6 is slidably connected to two bolts 8, and each bolt 8 is threaded with a nut 9. The support frame 6 is slidably connected to the outside of the bolts 8.

[0030] Each fixed frame 3 is externally connected to two bolts 10, and each bolt 10 is externally connected to a nut 11. The support frame 7 is externally connected to the bolts 10.

[0031] Support frame 1 6 and support frame 2 7 are respectively installed on the outside of the movable base 2 and the fixed frame 3 by bolt 1 8 and nut 1 9 and bolt 2 10 and nut 2 11. At the same time, the connection method of bolts and nuts is easy to disassemble, which facilitates the maintenance and replacement of the protective cloth 4.

[0032] Each fixed bracket 3 has a round hole 12 at both ends, and each protective cloth 4 has a mounting hole 13 at both ends. The protective cloth 4 is slidably connected to the outside of the support shaft 5 through the mounting hole 13. The two ends of the support shaft 5 are slidably connected to the inside of the two round holes 12. Each support shaft 5 is fixedly installed with a screw 14 on the outside. Each screw 14 is threaded with a nut 15 to prevent the support shaft 5 from moving. The connection method of the screw 14 and the nut 15 also facilitates the disassembly of the support shaft 5, so as to facilitate the disassembly of the protective cloth 4.

[0033] The base 1 has a storage slot 16 on one side corresponding to each fixed frame 3. The fixed frame 3 is slidably connected to the inside of the storage slot 16. The base 1 has threaded holes 18 at both ends corresponding to each storage slot 16. The threaded holes 18 are connected to the inside of the storage slot 16. Each threaded hole 18 is threaded with a threaded rod 17. The storage slot 16 reduces the distance between the fixed frame 3 and the base 1, reducing the space occupied by the overall equipment during transportation. The threaded rod 17 and the threaded hole 18 facilitate the stability of the fixed frame 3 in the storage state and during use.

[0034] Working principle:

[0035] In the first step, when the movable base 2 slides outside the base 1, one end of the protective cloth 4 is set outside the movable base 2 and the other end is set outside the fixed frame 3. The two ends of the protective cloth 4 are slidably connected to the outside of the two support shafts 5 respectively. The sliding of the movable base 2 will drive the protective cloth 4 to slide on the support shafts 5, thereby realizing the extension and retraction of the protective cloth 4. During the paper product stacking process, the suction cup of the palletizer descends to a suitable position above the paper product, and the suction cup connects to the vacuum to start sucking the paper product. After being sucked, the mechanical arm or other handling mechanism of the palletizer will transport the paper product to the designated stacking area. During this process, the movement of the movable base 2 will cause the two protective cloths 4 to extend or retract, protecting the guide rail area on the base 1 and preventing impurities from entering the guide rail area on the base 1.

[0036] The second step is to rotate nut 15 to disconnect it from screw 14, then pull support shaft 5 to disconnect it from protective cloth 4, then rotate nut 9 to disconnect it from bolt 8, then rotate nut 11 to disconnect it from bolt 10. At this time, support frame 6 and support frame 7 can be pulled to disconnect them from bolts 8 and 10. Protective cloth 4 is then disassembled, and workers can then clean it.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
