[0002] The clamping and feeding of the base paper roll is an important processing step in the production process of corrugated board, and the clamping and feeding equipment is an indispensable and important equipment in the feeding process. Its main function is to stably clamp the base paper roll of the cardboard and deliver the base paper to the subsequent workstation by rotating the roll. During the clamping process, the equipment needs to extend the clamp into the inner cylinder of the base paper roll, and after fixing the base paper roll, drive the base paper roll to rotate and feed.

[0003] At present, the common method of fixing the base paper roll chuck and the base paper roll in the workshop is to extend it and then expand it to fix it. For example, patent CN209973817U discloses a base paper rack slider expansion chuck. After this type of chuck is placed in the roll, the paper clamping and paper unwinding of the base paper roll are achieved by expanding and retracting the slider, that is, by expanding the outer wall of the chuck. However, in actual application, due to the insufficient hardness of the base paper roll, the slider is easily embedded in the inner tube of the roll after expanding, resulting in the slider being unable to retract and exit smoothly during retraction and unwinding, and manual assistance is required for unwinding, and there is a situation where the paper unwinding speed is slow and manual supervision is required. Moreover, this method of clamping the paper by expansion will damage the base paper of the innermost layer of the roll, causing part of the innermost layer of the base paper to be unusable due to damage, resulting in waste of base paper and increasing the production and processing costs of the enterprise.

[0033] Embodiment 1:

[0034] The present embodiment provides a cardboard base paper roll clamping device, which is mainly used in corrugated cardboard processing equipment. Its purpose is to clamp the base paper roll and then bracket it, so that the base paper roll can be rotated and loaded under the clamping of the clamping device, and the base paper is transported to the rear station. Based on the design of the chuck 20 in the current clamping device, the base paper roll is easily damaged during the actual processing process, which makes it difficult to unwind the paper, and requires manual equipment to assist in unwinding the paper, and will cause damage to the inner layer of the base paper roll, resulting in some base paper being unable to be used normally. The clamping device in this embodiment optimizes the design of the chuck 20, and through the ingenious structural design, when the chuck 20 is placed in the base paper roll for clamping, it will not cause damage to the base paper roll, and it will be fast and smooth when unwinding the paper, without getting stuck, thereby improving the processing efficiency. At the same time, the inner layer of the base paper roll will not be damaged, avoiding the waste of resources.

[0035] For detailed structure, please refer to Figure 1-5 The cardboard base paper roll clamping device in this embodiment includes a base 10, a chuck 20 and a gear ring sleeve 30, wherein the base 10 is mainly used to complete the connection between the clamping device and the processing equipment, and to fix the chuck 20 on the processing equipment. The chuck 20 is used to extend into the inner cylinder of the base paper roll. During the extension process, the chuck 20 abuts and clamps against the base paper roll to complete the paper clamping operation. The gear ring sleeve 30 is used for auxiliary limiting, that is, after the chuck 20 clamps the paper, the gear ring sleeve 30 is meshed with the inner cylinder of the base paper roll to further stabilize the clamping state between the chuck 20 and the base paper roll.

[0036] Furthermore, one end of the chuck 20 is fixedly mounted on the base 10, and is rotatably connected to the rotating shaft of the rotating mechanism through the base 10, wherein the rotating shaft of the rotating mechanism can drive the rotation of the base paper roll by driving the chuck 20 to rotate. Of course, in some processing equipment, the rotation of the base paper roll can also be driven by the storage device of the subsequent processing equipment, and the rotating mechanism here serves as an auxiliary. In order to ensure that the chuck 20 can extend into the base paper roll for effective abutment and clamping, the cross-section of the chuck 20 is set to be circular, and a limiting portion 21, a slope portion 22 and a tapered portion 23 are sequentially set in the direction away from the base 10, and the gear ring sleeve 30 is nested on the limiting portion 21 of the chuck 20, and a plurality of gear teeth 31 are protruding in the direction of the tapered portion 23. In the specific setting, the diameter of the slope portion 22 gradually decreases from the end close to the limiting portion 21 to the end of the tapered portion 23; the tapered portion 23 is set to be conical. The advantage of this design is that the tapered portion 23 of the chuck 20 first enters the inner cylinder of the base paper roll. If the chuck 20 and the inner cylinder are not aligned with the center of the inner cylinder of the base paper roll, the tapered portion 23 can be used to guide the chuck 20 so that it can be smoothly placed in the inner cylinder of the base paper roll, and the chuck 20 and the base paper roll are tightly connected through the cooperation of the inclined portion 22 and the inner cylinder, so that the chuck 20 can drive the base paper roll to rotate and feed. After the chuck 20 and the base paper roll are tightly clamped, the gear teeth 31 on the gear ring sleeve 30 are embedded in the inner cylinder of the base paper roll to strengthen the connection between the chuck 20 and the base paper roll.

[0037] When the current chuck 20 is placed into the base paper roll, the operator needs to accurately align the center of the chuck 20 with the center of the base paper roll before placing it, otherwise it is easy to wear the inner tube of the base paper roll, and then damage the base paper roll. This refined operation requires the operator to make real-time corrections, and the calibration time is long, which prolongs the roll change time. For this reason, in this embodiment, the cone head 231 of the conical part 23 is set to an arc spherical surface. During the placement process, as long as the center point of the cone head 231 is in the inner tube, the chuck 20 can gently correct the inner position of the base paper roll through the arc spherical surface when it is placed into the inner tube, and then the chuck 20 can be smoothly placed without damaging the inner tube of the base paper roll. Preferably, the inclination slope of the tapered portion 23 is greater than the inclination slope of the inclined portion 22. The large slope design of the tapered portion 23 can reduce the length of the chuck 20, so that the chuck 20 placed in the base paper roll can quickly allow the inclined portion 22 to be squeezed and relatively tightened with the inner tube of the base paper roll, saving paper clamping time and improving production efficiency. The inclination slope of the inclined portion 22 is gentle, so that during the placement of the chuck 20, the inclined portion 22 can be gradually abutted and tightened with the inner tube without damaging the base paper roll, thereby completing the clamping between the chuck 20 and the base paper roll. Preferably, in this embodiment, the inclination of the inclined portion 22 is 4-8°, and the cone angle of the tapered portion 23 is 45-50°. In a specific embodiment, the inclination of the inclined portion 22 is 5°, and the cone angle of the tapered portion 23 is 48°.

[0038] Since the clamping of the chuck 20 and the base paper roll is abutting clamping, in certain circumstances, such as the softening of the inner tube of the base paper roll and other low-probability quality reasons, the base paper roll and the chuck 20 may become loose, causing the processing equipment to fail and affecting the processing process. In this embodiment, the limiting portion 21 of the chuck 20 is set as a plane, and the outer ring of the gear ring sleeve 30 is evenly opened, and is installed on the limiting portion 21 of the chuck 20 by setting a split pin. The protruding height of the gear teeth 31 of the gear ring sleeve 30 is adapted to the length of the limiting portion 21. When the chuck 20 is placed in the base paper roll, it is clamped with the inner tube through the inclined portion 22, and the protruding caliper of the gear teeth 31 of the gear ring sleeve 30 is clamped on the inner tube to perform secondary limiting to prevent the base paper roll from loosening and improve the processing safety factor. This type of clamp only performs circumferential limiting. When unwinding the paper, the chuck 20 is axially withdrawn, and it is not easy for the gear ring sleeve 30 to get stuck with the inner tube. This can avoid the problem of the clamping device not being able to unwind the paper smoothly to the greatest extent. In order to ensure the limiting effect, multiple gear teeth 31 are evenly arranged along the center of the gear ring sleeve 30, and an inverted trapezoidal groove 32 is arranged between adjacent gear teeth 31. This design reduces the situation where the gear teeth 31 are unstable on the inner tube. It is further preferred that the inner diameter of the gear ring sleeve 30 is compatible with the diameter of the limiting portion 21 of the chuck 20. This design is mainly to allow the gear ring sleeve 30 to be effectively installed on the limiting portion 21 of the chuck 20.

[0039] The main function of the inclined portion 22 is to clamp with the inner cylinder of the base paper roll. In order to achieve the clamping purpose, the minimum diameter of the inclined portion 22 is larger than the inner cylinder diameter of the base paper roll, and the maximum diameter is larger than the inner cylinder diameter of the base paper roll. When the chuck 20 is placed in the inner cylinder and the inclined portion 22 abuts against the inner cylinder, the inner cylinder is squeezed by the inclined portion 22 during the continuous placement of the chuck 20, and gradually expands slowly. Finally, when it is placed in the deepest part of the inclined portion 22, that is, when it has the maximum diameter, it clamps with the toothed ring sleeve 30 on the limiting portion 21 to achieve clamping with the chuck 20.

[0040] In order to improve the clamping strength of the base paper roll in the processing equipment, a concave platform can be set on the inner cylinder of the base paper roll. Figure 4 and Figure 5 Correspondingly, the chuck 20 is further provided with a secondary clamping portion 40 between the limiting portion 21 and the base 10, wherein the secondary clamping portion 40 cooperates with the recessed platform, a second inclined portion 41 is provided on the secondary clamping portion 40, and a second gear ring sleeve 42 is sleeved at the connection with the bottom. The chuck 20 cooperates with the recessed platform of the base paper roll through the secondary clamping portion 40, which can improve the firmness between the two and ensure that they will not loosen.

[0041] It is worth noting that, in actual use, two clamping devices are provided, and the two clamping devices are respectively provided on both sides of the base paper roll, and are respectively placed into the inner cylinder of the base paper roll through the clamping head 20, so as to clamp the base paper roll.

The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application.
