Description

Technical Field

[0001] The utility model relates to the field of paper conveying belt racks, in particular to a paper conveying belt rack with buffering capability. Background Art

[0002] During the paper conveying process, the belt needs to fit the paper and support the paper to ensure that the paper can be released from the paper roll smoothly and that the paper can be conveyed stably. To this end, the conveyor frame with the belt installed needs to be able to rise so that the belt can support the paper and improve the fit between the belt and the paper. The principle is similar to the tensioning of the tensioning wheel and the conveying wire.

[0003] As the base paper is conveyed, the roll diameter of the base paper roll will change, so that the frame with a belt needs to be able to rise and fall to adapt to the conveying of the base paper in real time. For this purpose, a hydraulic cylinder or a pneumatic cylinder is usually used to control the rise and fall of the frame. On the other hand, after the base paper on the base paper roll is conveyed, the base paper roll needs to be replaced, so the frame with the belt needs to be lowered to replace the base paper. After the replacement is completed, the frame rises, and the belt fits the base paper to continue conveying the base paper.

[0004] When the rack is lowered, due to its heavy weight and large inertia, the rack will have a large impact on the ground or the support blocks installed on the ground for supporting the rack. In the long run, not only the ground and / or the support blocks will be damaged, but also the rack. Therefore, it is necessary to solve this technical problem. Utility Model Content

[0022] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0023] Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0024] Example 1

[0025] like Figure 1-Figure 2 As shown, a paper feeding belt rack with buffering capacity comprises a support member 2 and a frame 1 with a belt, wherein the support member 2 has a support surface 21 for supporting the frame 1, and the frame 1 can be placed on the support surface 21 after being lowered; a driving device 7 and a buffering device are arranged between the frame 1 and the support surface 21; wherein the driving device 7 can drive the frame 1 to rise or fall, and the driving mechanism drives the frame 1 to rise, so that the belt supports the base paper and improves the fit of the belt to the base paper, and continues to convey the base paper; the driving mechanism lowers the frame 1, and the base paper roll can be replaced; the buffering device buffers the impact force generated when the frame 1 is lowered.

[0026] In this embodiment, by installing a buffer device between the conveyor belt frame 1 and the ground or the support block, the impact of the frame 1 on the ground or the support block can be effectively reduced, thereby reducing damage to the ground and / or the support block, and also reducing damage to the frame 1.

[0027] Example 2

[0028] On the basis of Example 1, a specific implementation method of the buffer device is further proposed.

[0029] In the first embodiment, the buffer device is a first angle iron piece 4 and a second angle iron piece 5, and the first angle iron piece 4 and the second angle iron piece 5 are matched; the first angle iron piece 4 is arranged on the frame 1, and the second angle iron piece 5 is arranged on the support surface 21; the angle iron pieces prevent the frame 1 from directly contacting the support surface 21, and can withstand most of the impact. At the same time, the large area of ​​the angle iron pieces disperses the impact force, thereby reducing the damage to the ground and / or the support block, and also reducing the damage to the frame 1.

[0030] The second embodiment adds an elastic pad 6 on the basis of the first embodiment, and is arranged between the second angle iron piece 5 and the supporting surface 21; the elastic pad 6 can be a rubber pad, which can deform and simultaneously convert the impact force received into potential energy storage, thereby reducing the damage to the ground and / or the supporting block, and also reducing the damage to the frame 1.

[0031] In a third embodiment, the buffer device is a damping rod 3, one end of which is hinged to the frame 1, and the other end of the damping rod 3 is hinged to the support surface 21. The damping rod 3 will generate damping when the length changes, that is, when the frame 1 is lowered, the frame 1 will move closer to the support surface 21, so that the length of the damping rod 3 changes, and then the damping rod 3 generates damping, which effectively reduces the lowering speed of the frame 1. In particular, when the driving device 7 fails suddenly, the frame 1 can still receive the damping effect and will not have an excessive impact, that is, it can reduce the damage to the ground and / or the support block, and also reduce the damage to the frame 1.

[0032] In the third embodiment, the damping rod 3 is a hydraulic damping rod 3 or a pneumatic damping rod 3; the hydraulic damping rod 3 and the pneumatic damping rod 3 are both commonly used damping rods 3 in the art and can be purchased on the market, and their specific structures will not be described in detail in this specification.

[0033] In the third embodiment, the two ends of the damping rod 3 are hinged, and the length of the damping rod 3 itself can be changed, so there is no motion interference, and the rack 1 can be effectively lowered.

[0034] In addition, in the third embodiment, the damping rod 3 is a telescopic rod, having a movable rod and a fixed rod, and the movable rod is slidably connected to the fixed rod; a positioning ring 32 is provided on the movable rod and the fixed rod, and a compression spring 31 is sleeved on the telescopic rod and between the two positioning rings 32. When the frame 1 is lowered and moved closer to the supporting surface 21, the movable rod slides against the fixed rod, the telescopic rod shortens, and the two positioning rings 32 approach, thereby compressing the compression spring 31, thereby realizing the conversion of the impact force of the frame 1 into potential energy storage, so that the supporting surface 21 will not be subjected to excessive impact, that is, the damage to the ground and / or the supporting block can be reduced, and the damage to the frame 1 can also be reduced.

[0035] It should be noted that the above three embodiments are only rubber pads relative to the buffer device, which can prevent the rubber pads from breaking and causing hard contact between the frame 1 and the supporting surface 21 of the support member 2.

[0036] It should be noted that any multiple implementations of the three implementations may exist between the frame 1 and the support surface 21 at the same time.

[0037] In a feasible implementation manner, buffer devices are provided on both sides of the frame 1 to improve the buffering stability and the balance of the force applied to the frame 1 during buffering.

[0038] Example 3

[0039] On the basis of any one of the implementations in Examples 1-2, a specific implementation method of the driving device 7 is further proposed.

[0040] The driving device 7 is a driving cylinder, which is a hydraulic telescopic cylinder or a pneumatic telescopic cylinder. The hydraulic telescopic cylinder and the pneumatic telescopic cylinder are both commonly used driving devices 7 in this field and can be purchased on the market. Their specific structures will not be described in detail in this specification. One end of the driving cylinder is hinged to the support 2, and the other end of the driving cylinder is hinged to one end of the frame 1. The middle part of the frame 1 has a rotating shaft 8 for installing the frame 1. The rotating shaft 8 is fixed to other devices or structures in the factory building, and the frame 1 can rotate around the rotating shaft 8. The driving rod is extended, so that the lower end of the frame 1 is away from the support 2, the frame 1 rotates around the rotating shaft 8, and the upper part of the frame 1 is close to the support 2, and the frame 1 is lowered; the driving rod is shortened, so that the lower end of the frame 1 is close to the support 2, the frame 1 rotates around the rotating shaft 8, and the upper part of the frame 1 is away from the support 2, and the frame 1 is raised.

[0041] In this embodiment, the support member 2 may be the ground or a support block installed on the ground for supporting the rack 1, or may be a wall of a factory building, which is determined according to actual conditions.

[0042] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
