Description

Technical Field

[0001] This utility model relates to the field of paper production technology, specifically a limiting structure for paper transportation. Background Technology

[0002] Paper, made from plant fibers, is a non-woven material that can be folded at will for writing. Printing is the technology of mass-producing the content of original manuscripts such as text, pictures, photos, and anti-counterfeiting materials by transferring ink to the surface of materials such as paper, textiles, plastics, and leather through processes such as plate making, inking, and pressing. Before and after printing, transportation equipment is needed to move the raw paper and the finished paper. Existing transportation equipment uses trailers or manual handling.

[0003] Publication No. CN209553253U discloses a transport device for printed paper. The carrier plate is tilted during transport, and under its own weight and the action of side baffles, it can prevent stacked paper from tilting or slipping during transport, thus avoiding damage to the paper. It is equipped with a picking slot and a side passage for easy handling and paper loading / unloading. Additionally, it allows for quantitative picking of stacked paper by referring to scale markings. The push rod is retractable, making it suitable for people of different heights and easy to use. However, this patent still has the following problems in actual use:

[0004] Although this type of transport device for printing paper is tilted during transport by means of a support plate, and under its own weight and the action of the side baffles, it can prevent the stacked paper from tilting or slipping during transport, the paper is still susceptible to being blown away by the wind during transport, thus affecting the transport of the paper.

[0005] A limiting structure for paper transport is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a limiting structure for paper transportation, in order to solve the problem mentioned in the background art that, in the current method, the supporting plate is tilted during transportation. Under its own weight and the action of the side baffles, it can prevent the stacked paper from tilting and slipping during transportation. However, the paper is easily blown away by the wind during transportation, which affects the transportation of the paper.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a limiting structure for paper transportation, including a limiting mechanism and a turntable installed on one side of the limiting mechanism;

[0008] The bottom of the limiting mechanism is provided with a lifting mechanism and a hydraulic cylinder installed at the bottom of the lifting mechanism.

[0009] Also includes:

[0010] The limiting mechanism includes a trolley, the top of which is fixedly connected to a bracket, and the top of which is fixedly connected to a clamping frame.

[0011] One side of the clamping frame is rotatably connected to a worm gear, one end of which passes through the clamping frame and is fixedly connected to the turntable;

[0012] One side of each end of the worm is meshed with a worm wheel.

[0013] Preferably, a bidirectional threaded rod is fixedly connected to the center position inside each of the two worm gears, and both ends of the bidirectional threaded rod are rotatably connected to the clamping frame.

[0014] Preferably, the two ends of the bidirectional threaded rod are symmetrically threaded with threaded sleeves, one end of the threaded sleeve is fixedly connected to a connecting block, and one end of the connecting block is fixedly connected to a limit frame.

[0015] Preferably, a plurality of limiting frames are fixedly connected to one side of the limiting frame, the number of limiting frames being eleven, and the limiting frames are evenly distributed on one side of the limiting frame, and the paper body is attached to the inside of the limiting frame.

[0016] Preferably, the lifting mechanism includes a base plate, the bottom of which is fixedly connected to a trolley, and one side of the top of the base plate is rotatably connected to a hydraulic cylinder, the output end of which is rotatably connected to a connecting rod assembly.

[0017] Preferably, a first connecting seat is rotatably connected to one end of the upper and lower sides of the connecting rod assembly, and a second connecting seat is rotatably connected to the other end of the upper and lower sides of the connecting rod assembly, with a frame slidably connected to the outer side of the second connecting seat.

[0018] Preferably, a top plate is fixedly connected to the top side of the upper frame of the linkage assembly, and a support frame is fixedly connected to the top of the top plate, with the top of the support frame being in close contact with the paper body.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This limiting structure for paper transportation can quickly clamp and limit the paper body by setting a limiting mechanism, preventing the paper from falling during transportation. The lifting mechanism can adjust the height of the paper body, facilitating its handling and storage. The specific details are as follows:

[0020] 1. By setting a limiting mechanism, the paper body can be quickly clamped and limited to prevent the paper from falling during transportation. The turntable drives the worm to rotate, and the meshing between the worm and the worm wheel drives the bidirectional threaded rod to rotate. The thread action between the bidirectional threaded rod and the threaded sleeve drives the two limiting frames to move in opposite directions at the same time, so as to clamp and limit the paper body of the same model.

[0021] 2. By setting up a lifting mechanism, the height of the paper body can be adjusted, making it easier to pick up or store the paper body. The piston rod of the hydraulic cylinder extends and drives the connecting rod assembly to rotate around the first connecting seat and the second connecting seat. At the same time, the connecting rod assembly drives the second connecting seat to move within the frame, thereby changing the height position of the top plate and thus changing the height of the paper body.

[0031] A worm gear 104 is rotatably connected to one side of the clamping frame 103. One end of the worm gear 104 passes through the clamping frame 103 and is fixedly connected to the turntable 105. A worm wheel 106 is meshed with one side of both ends of the worm gear 104. A bidirectional threaded rod 107 is fixedly connected to the center of each of the two worm wheels 106. Both ends of the bidirectional threaded rod 107 are rotatably connected to the clamping frame 103. The meshing action between the worm gear 104 and the worm wheel 106 drives the bidirectional threaded rod 107 to rotate. The thread action between the bidirectional threaded rod 107 and the threaded sleeve 108 drives the two limiting frames 111 to move towards each other simultaneously, thereby clamping and limiting the paper body 112 of the same type.

[0032] The two ends of the bidirectional threaded rod 107 are symmetrically threaded with threaded sleeves 108. One end of the threaded sleeve 108 is fixedly connected to a connecting block 109. One end of the connecting block 109 is fixedly connected to a limiting frame 110. A number of limiting frames 111 are fixedly connected to one side of the limiting frame 110. There are eleven limiting frames 111, and the limiting frames 111 are evenly distributed on one side of the limiting frame 110. The paper body 112 is attached to the inside of the limiting frame 111. The limiting frames 111 are used to separate and store the paper body 112.

[0033] The lifting mechanism 2 includes a base plate 201. The bottom of the base plate 201 is fixedly connected to the trolley 101. One side of the top of the base plate 201 is rotatably connected to a hydraulic cylinder 202. The output end of the hydraulic cylinder 202 is rotatably connected to a connecting rod assembly 203. One end of the upper and lower sides of the connecting rod assembly 203 is rotatably connected to a first connecting seat 204. The other end of the upper and lower sides of the connecting rod assembly 203 is rotatably connected to a second connecting seat 205. A frame 206 is slidably connected to the outside of the second connecting seat 205.

The top of the support frame 208 is attached to the paper body 112. The first connecting seat 204 on the top side of the linkage assembly 203 is fixedly connected to the top plate 207.

[0035] Working principle: Before using this limiting structure for paper transportation, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6 As shown, firstly, the paper body 112 is placed in the corresponding limiting frame 111, and the bottom is disengaged from the support frame 208. Then, the turntable 105 is rotated, which drives the worm gear 104 to rotate. The meshing action between the worm gear 104 and the worm wheel 106 drives the bidirectional threaded rod 107 to rotate. The thread action between the bidirectional threaded rod 107 and the threaded sleeve 108 drives the two limiting frames 111 to move towards each other simultaneously, thus clamping and limiting the paper body 112 of the same model, which can prevent the paper body 112 from falling during transportation.

[0036] Secondly, when it is necessary to take out the paper body 112, first loosen the limiting frame 111 to release the limitation on the paper body 112, and then start the piston rod of the hydraulic cylinder 202 to extend and drive the connecting rod assembly 203 to rotate around the first connecting seat 204 and the second connecting seat 205. At the same time, the connecting rod assembly 203 drives the second connecting seat 205 to move within the frame 206, thereby changing the height position of the top plate 207, thereby changing the height of the paper body 112, and extending the paper body 112 out of the clamping frame 103, which makes it easy to take out the paper body 112.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
