Description

Technical Field

[0001] The invention relates to the technical field of paper printing, in particular to an anti-curling paper air-drying device for printing. Background Art

[0002] With the development of printing technology, computer printers and copying technology, the requirements for paper smoothness are getting higher and higher. If the paper curls or has poor dimensional stability, it will be stacked unevenly, affecting the paper feeding and output of printers and copiers, and causing adjustments and running directions during the printing process. Simply put, if the front and back of the paper react differently to changes in humidity or it contains a Z-direction humidity decrease, once the paper roll is off the machine, the paper will curl. If the force relative to the fiber shrinkage or expansion exceeds the toughness of the paper, curling will occur. If the drying is asymmetrical or uneven, the paper will also curl. There are some devices for air-drying paper in the prior art, but these devices generally have low air-drying efficiency.

[0003] For example, Chinese application number CN201420141951.6 discloses a paper air-drying device, which includes an air-drying rack, a fan mounting frame, and a clamping unit; the clamping unit and the fan mounting frame are mounted on the air-drying rack, and the fan mounting frame is located below the clamping unit; the key is that the clamping unit includes a front clamping plate, a rear clamping plate, and a paper jam ball disposed therebetween, and the distance between the front clamping plate and the rear clamping plate is larger at the top and smaller at the bottom, and the smallest distance is smaller than the diameter of the paper jam ball. However, the device has the following disadvantages: First, although the structure of the clamping mechanism can reduce damage to the paper, the setting of the baffle makes it inconvenient to fix and remove the paper to be air-dried, which makes the clamping and removal process of the paper cumbersome, the air-drying efficiency is low, and the manual operation is virtually increased.

[0004] Another example is Chinese application number CN201821174779.9, which discloses a paper clamping and air-drying device, which includes an air-drying rack and a clamping mechanism, wherein the clamping mechanism is installed on the air-drying rack, and the clamping mechanism includes a front clamping plate, a rear clamping plate, and an extrusion fixing component, wherein the extrusion fixing component is arranged between the front clamping plate and the rear clamping plate, and the extrusion fixing component includes a housing and a left pressing block, a right pressing block, and a counterweight block arranged in the housing, wherein the left pressing block and the right pressing block are connected by an elastic member, and the counterweight block passes through an elastic ring formed by the elastic member. The present invention is cleverly designed, and can conveniently and efficiently realize the hanging and removal of paper, reducing the labor intensity of manual labor, and the device can be disassembled and assembled by itself, which is convenient for storage and does not occupy storage space. However, the device has the following defects in use: the clamping mechanism only clamps the upper two ends of the paper, and the corners of the lower side of the paper are prone to curling. Secondly, since the clamping mechanism is distributed in a vertical space, it is inconvenient to fix. Summary of the invention

Detailed implementation mode

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] As Figures 1 to 6 shown, a paper air-drying device for preventing curling during printing includes a storage rack 1, an air-drying rack 2, a guide rack 3, a turning mechanism, and a lifting and feeding mechanism. The air-drying rack 2 is located on the right side of the storage rack 1. Both ends of the guide rack 3 are connected to the storage rack 1 and the air-drying rack 2. Six air-drying storage frames 4 for clamping paper are provided on the storage rack 1, and the six air-drying storage frames 4 are distributed vertically one above the other. The turning mechanism is arranged between the storage rack 1 and the air-drying rack 2, and is used to turn the air-drying storage frame 4 at the uppermost position on the storage rack 1 along the guide rack 3 to the air-drying rack 2. Four groups of lifting and feeding mechanisms are provided, corresponding to being arranged around the storage rack 1, and are used to lift and feed the remaining air-drying storage frames 4 upward after the air-drying storage frame 4 at the uppermost position is turned away.

[0029] Further, left vertical guide grooves 11 and right vertical guide grooves 12 are correspondingly arranged on the storage rack 1. There are two left vertical guide grooves 11, which are distributed front and back. There are two right vertical guide grooves 12, which are distributed front and back. On the air-drying rack 2, upper horizontal guide grooves 21 and lower horizontal guide grooves 22 are correspondingly arranged. There are two upper horizontal guide grooves 21, which are distributed front and back. There are two lower horizontal guide grooves 22, which are distributed front and back. On the guiding rack 3, outer arc guide grooves 31 and inner arc guide grooves 32 are correspondingly arranged. There are two outer arc guide grooves 31, which are distributed front and back. There are two inner arc guide grooves 32, which are distributed front and back. The left end openings of the two outer arc guide grooves 31 are correspondingly connected to the upper openings of the two left vertical guide grooves 11, and the right end openings are correspondingly connected to the left openings of the two upper horizontal guide grooves 21. The left end openings of the two inner arc guide grooves 32 are correspondingly connected to the upper openings of the two right vertical guide grooves 12, and the right end openings are correspondingly connected to the left openings of the two lower horizontal guide grooves 22. A number of air-drying storage frames 4 are correspondingly and slidably mounted in the two left vertical guide grooves 11 and the two right vertical guide grooves 12.

[0030] In this embodiment, six air-drying storage frames 4 are provided. Four sliding bumps 41 that are slidably matched with the two left vertical guide grooves 11 and the two right vertical guide grooves 12 are arranged on the side walls of the six air-drying storage frames 4. Four clamping bottom plates 42 and four clamping assemblies that cooperate with the clamping bottom plates 42 are arranged around the upper frame end faces of the six air-drying storage frames 4. The lifting and loading mechanism abuts against the sliding bumps 41 on the lowermost air-drying storage frame 4. Through the upward lifting of the lifting and loading mechanism, when the uppermost air-drying storage frame 4 is turned, the air-drying storage frame 4 on the second layer moves upward to the uppermost position, realizing loading.

[0031] As a further improvement of this embodiment, the four clamping assemblies each include a clamping cover plate 5 rotatably mounted on the upper frame end face of the air-drying storage frame 4, a pressing pad 51 arranged on the cover plate face of the clamping cover plate 5. A threaded through hole 52 is arranged on the clamping cover plate 5 and close to the rotating end. A threaded connection hole 43 that is symmetrically distributed with the threaded through hole 52 along the rotation axis of the clamping cover plate 5 is arranged on the upper frame end face of the air-drying storage frame 4. The pressing pad 51 is made of an elastic material, which can ensure clamping the paper without damaging the paper. Three of the threaded through holes 52 and the threaded connection holes 43 are provided in each clamping assembly. After the clamping cover plate 5 is turned and clamped, the clamping cover plate 5 is fixed after being connected by a bolt passing through the threaded through hole 52 and the threaded connection hole 43, thereby realizing clamping of the paper.

[0032] On the lower frame end faces of all six air-drying storage frames 4, there are support and limit retaining bars 44 that abut against the upper frame end faces of adjacent air-drying storage frames 4. There are four of the support and limit retaining bars 44, which are correspondingly distributed on the left and right sides of the lower frame end face. When the air-drying storage frame 4 is located on the storage rack 1, the support and limit retaining bars 44 play a role in supporting the air-drying storage frame 4 above; when the air-drying storage frame 4 is located on the air-drying rack 2, the support and limit retaining bars 44 play a role in limiting and separating two adjacent air-drying storage frames 4, thereby ensuring that the paper is fully air-dried.

[0033] As a further improvement of this embodiment, the lifting and loading mechanism includes a lifting cylinder 6 arranged on the lower frame part of the storage rack 1, and a lifting chuck 61 connected to the lifting cylinder 6 and abutting against the sliding convex block 41 on the lowermost air-drying storage frame 4. The lifting chuck 61 has a V-shaped structure, which can better engage with the sliding convex block 41.

[0034] As a further improvement of this embodiment, the turning mechanism includes a rotating plate 7 located between the storage rack 1 and the air-drying rack 2, a turning plate 71 arranged on the rotating plate 7, a turning gear 72 coaxially connected to the turning plate 71, a driving gear 73 meshingly connected to the turning gear 72, and a driving motor 74 connected to the driving gear 73. The driving motor 74 and the driving gear 73 are arranged on the rotating plate 7. There is a support platform 8 between the storage rack 1 and the air-drying rack 2. The support platform 8 is correspondingly fixedly connected to the air-drying rack 2. A rotating motor 9 is arranged at the bottom of the support platform 8. The rotating plate 7 is installed on the support platform 8 and is connected to the rotating motor 9 at the bottom. The horizontal height of the turning plate 71 is between the uppermost air-drying storage frame 4 and the second-layer air-drying storage frame 4, and the upper plate surface of the turning plate 71 can be attached to the lower frame end face of the uppermost air-drying storage frame 4. Further, on the upper and lower side plate surfaces of the turning plate 71 near the rotating shaft, two vertically distributed side baffles 75 are symmetrically arranged.

[0035] The movement process of the above-mentioned turning mechanism is as follows: In the non-turned state, the turning plate 71 is located on the right side of the rotating shaft. When turning, the rotating plate 7 first rotates horizontally, rotating the turning plate 71 to the lower right side of the uppermost air-drying storage frame 4. Then, the driving motor 74 drives the turning plate 71 to rotate clockwise through the driving gear 73 and the turning gear 72. Under the guiding action of the guide groove on the guiding frame 3, the uppermost air-drying storage frame 4 is turned to the air-drying rack 2. During the turning process, the side baffles 75 play a role in limiting and supporting.

[0036] The working principle and usage process of the present invention:

[0037] During use, the staff lays the paper flat on the uppermost air-drying storage frame 4, and the four corners of the paper are located on the four clamping base plates 42. Then, the four clamping covers 5 located around the air-drying storage frame 4 are flipped so that the pressing pads 51 press on the four corners of the paper. Then, bolts are passed through the threaded through holes 52 and screwed into the threaded connection holes 43. After the paper is clamped, the rotating motor 9 drives the rotating plate 7 to rotate, so that the turning plate 71 moves to the bottom right end of the uppermost air-drying storage frame 4. Then, the driving motor 74 is started to drive the driving gear 73 to rotate counterclockwise, and the turning plate 71 is driven to rotate clockwise through the turning gear 72, and the uppermost air-drying storage frame 4 is dialed clockwise onto the air-drying rack 2 along the guiding of the outer arc-shaped guide groove 31 and the inner arc-shaped guide groove 32 on the guiding frame 3. When the turning plate 71 rotates to 90°, the air-drying storage frame 4 changes from a horizontal state to a vertical state. Then, the turning plate 71 continues to dial until it disengages from the air-drying storage frame 4, and the air-drying storage frame 4 slides to the right end of the air-drying rack 2 in a vertical state under the guiding of the upper horizontal guide groove 21 and the lower horizontal guide groove 22. At this time, the process of the air-drying storage frame 4 clamping the paper horizontally and drying the paper vertically is completed. On the other hand, after the uppermost air-drying storage frame 4 on the storage rack 1 is dialed onto the air-drying rack 2, the lifting cylinder 6 on the lower frame of the storage rack 1 is started, and the remaining five air-drying storage frames 4 are lifted upward for feeding through the lifting blocks 61. Then, the second air-drying storage frame 4 completes paper clamping and transfer to the air-drying rack 2 for drying according to the above process. Since the supporting and limiting rods 44 on each air-drying storage frame 4 prevent the adjacent two air-drying storage frames 4 from being in close contact with each other, there is enough space between them to ensure that the paper can be fully dried.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
