Description

Technical Field

[0001] This utility model relates to the field of paper product technology, and in particular to an automatic paper pressing and stacking machine after paper is folded. Background Technology

[0002] Automatic paper folding and stacking machines are commonly used for folding paper, facilitating subsequent storage, transportation, and distribution. Currently, the pressing direction of paper folding and stacking machines on the market is that the paper folding spine passes laterally across the pressure roller. The contact time and contact area between the folding spine and the pressure roller are short, resulting in a loose pressing effect. The folded paper is not pressed firmly, is uneven, and is not conducive to subsequent binding processes. This leads to low production efficiency, and the bound books are not sturdy, uneven, or aesthetically pleasing.

[0003] In view of this, there is a need to provide an automatic paper pressing and stacking machine after paper folding to overcome the shortcomings of the existing technology. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is to provide an automatic paper pressing and folding machine that is simple in structure, low in cost, low in failure rate, easy to maintain, and high in production efficiency. The folding spine has a long contact time and a large contact area with the pressure roller, which presses the folded paper tightly and flat, which is beneficial to the subsequent binding process. The bound book is strong, flat and beautiful.

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic paper pressing and stacking machine after paper folding, which includes a frame, a paper folding spine longitudinal pressing device, a paper correction conveying device, a paper lifting conveying device, and a paper stacking device installed on the frame. After the folded paper is corrected by the paper correction conveying device, it is conveyed to the paper folding spine longitudinal pressing device, where it is pressed firmly. At the same time, the paper lifting conveying device lifts the pressed paper and conveys it to the paper stacking device, where the paper stacking device stacks the pressed paper.

[0006] A further improvement of this utility model is that the longitudinal compaction device for the paper folding spine includes a compaction wheel assembly rotatably mounted on the frame, and a drive mechanism for driving the compaction wheel assembly to rotate.

[0007] A further improvement of this utility model is that the compaction wheel assembly includes a first wheel axle and a second wheel axle rotatably mounted on the lower part of the frame. The first wheel axle is located directly above the second wheel axle. A first compaction wheel is mounted on the first wheel axle, and a second compaction wheel is mounted on the second wheel axle. The first compaction wheel and the second compaction wheel face each other, and the distance between the first compaction wheel and the second compaction wheel is the thickness of the folded paper.

[0008] A further improvement of this utility model is that the driving mechanism includes a motor mounting base mounted on the frame, a drive motor mounted on the motor mounting base, a first sprocket mounted on the output shaft of the drive motor, a second sprocket mounted on the first sprocket shaft, and a first chain that drives and cooperates with the first sprocket and the second sprocket.

[0009] A further improvement of this utility model is that the driving mechanism further includes a driven mechanism for driving the second wheel shaft to rotate; the driven mechanism includes a first gear mounted on the first wheel shaft, a rotating shaft rotatably mounted on the frame, a second gear and a third sprocket respectively fixedly mounted on the rotating shaft, a fourth sprocket mounted on the second wheel shaft, and a second chain that drives and cooperates with the third sprocket and the fourth sprocket, wherein the first gear meshes with the second gear.

[0010] A further improvement of this utility model is that the paper correction and conveying device includes an inclined roller mechanism mounted on the frame and a linear positioning mechanism mounted on the inclined roller mechanism.

[0011] A further improvement of this utility model is that the inclined roller mechanism includes a bracket mounted on the frame, multiple rollers mounted obliquely on the bracket, a first synchronous pulley mounted on each roller, a motor base mounted on the frame, a first motor mounted on the motor base, a second synchronous pulley mounted on the output shaft of the first motor, and a first synchronous belt that is connected to the first synchronous pulley and the second synchronous pulley on each roller respectively.

[0012] A further improvement of this utility model is that the linear positioning mechanism includes a positioning plate mounted on the bracket, a bead movable plate mounted on the positioning plate, a bead baffle and a guide plate mounted on the bead movable plate, and the bead movable plate is provided with a plurality of circular through holes, each of which contains a ball bearing.

[0013] A further improvement of this utility model is that the paper rising and conveying device includes a third wheel shaft installed on the upper part of the frame, a first large roller installed on the third wheel shaft, a second large roller installed on the first wheel shaft, a belt tensioning mechanism installed on the frame, and tensioning belts respectively sleeved on the first large roller, the second large roller, and the belt tensioning mechanism.

[0014] A further improvement of this utility model is that the paper stacking device includes a paper input mechanism, a lifting mechanism, a paper support mechanism, and a paper sorting mechanism installed on the frame, and a paper receiving output mechanism installed on the lifting mechanism. The compacted paper is input from the paper input mechanism into the paper receiving output mechanism. The lifting mechanism drives the paper receiving output mechanism to move up and down. The paper sorting mechanism is used to tap the paper in the paper receiving output mechanism to expel air from the paper. When the paper receiving output mechanism is full of paper, the paper support mechanism supports the paper input by the paper input mechanism, and the paper receiving output mechanism outputs the stacked paper outward.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. After being corrected by the paper alignment conveyor, the folded paper is conveyed to the longitudinal compaction device at the folding ridge, where it is compacted. Simultaneously, the paper lifting conveyor raises the compacted paper and conveys it to the paper stacking device, which stacks the compacted paper. This invention has a simple structure, low cost, low failure rate, simple and convenient maintenance, and high production efficiency.

[0017] 2. The two compaction rollers of the compaction roller group are in complete longitudinal contact from beginning to end to compact and tighten the paper folding ridge. Therefore, the contact time between the folding ridge and the pressure roller is long and the contact area is large, so the folded part of the paper is pressed tightly and flat.

[0018] 3. When the folded parts of the folded paper are pressed tightly and flat, it is more conducive to the subsequent binding process, and the bound book is sturdy, flat and beautiful. Attached Figure Description

[0082] Specifically, such as Figure 1-3 As shown, the idler roller 6 is a non-powered straight sleeve idler roller.

[0083] This utility model also includes a control system, which is used to receive signals from the sensor 5111 and the positioning sensor, and to control the operation of the drive motor 222, the first motor 315, the lifting motor 5241, the translation motor 5343, the second motor 54441, and the output motor 555.

[0084] Working principle:

[0085] After being corrected by the paper correction conveyor 3, the folded paper 7 is conveyed to the longitudinal compaction device 2 at the folding spine of the paper. The longitudinal compaction device 2 at the folding spine of the paper is compacted. At the same time, the paper rising conveyor 4 raises the compacted paper and conveys it to the paper stacking device 5. The paper stacking device 5 stacks the compacted paper.

[0086] Specifically, after being folded, the paper 7 passes through the inclined roller mechanism 31, the linear positioning mechanism 32, and the paper transition device 33 before entering the longitudinal pressing device 2 at the folding ridge and the paper rising conveyor 4. The pressed paper is then fed from the paper input mechanism 51 to the paper receiving and output mechanism 55. The lifting mechanism 52 drives the paper receiving and output mechanism 55 to move up and down. The paper sorting mechanism 54 is used to tap the paper in the paper receiving and output mechanism 55 to expel the air from the paper. When the paper receiving and output mechanism 55 is full of paper, the paper supporting mechanism 53 supports the paper input by the paper input mechanism 51, and the paper receiving and output mechanism 55 outputs the stacked paper outward.

[0087] Specifically, the folded paper 7 exits the folding machine and enters the roller 312. The first motor 315 drives the 27 rollers 312 to rotate simultaneously through 27 first synchronous rollers 313, 27 second synchronous rollers 316, and the first synchronous belt 317. As the inclined rollers 312 rotate, the folded paper 7 generates an oblique force, causing the folded paper 7 to longitudinally press against the positioning plate 321. It is pressed by the ball bearings 325 and passes through the transition roller 333. The folded paper 7 then longitudinally enters the first pressing roller 213 and the second pressing roller 214. At the same time, the folded paper 7 enters the paper rising conveyor 4 through the transition roller 333.

[0088] The drive motor 222 drives the first wheel shaft 211 to rotate the first compaction wheel 213 through the first sprocket 223, the second sprocket 224, and the first chain 225. The first wheel shaft 211 drives the second wheel shaft 212 to rotate the second compaction wheel 214 through the first gear 2261, the second gear 2263, the third sprocket 2264, the fourth sprocket 2265, and the second chain 2266. The first compaction wheel 213 and the second compaction wheel 214 rotate in opposite directions, thus longitudinally compacting the folded paper 7 at the folded spine.

[0089] At the same time, the second wheel shaft 212 drives the three first large rollers 42 to rotate, and drives the three second large rollers 43 to rotate through the fifth sprocket 471, the sixth sprocket 472, and the third chain 473. The first large rollers 42 and the second large rollers 43 simultaneously drive the tension belts 45 to rotate, clamping the folded and compacted paper and moving it upward to the top. The folded and compacted paper is clamped by the two tension belts 45.

[0090] Sensor 5111 detects that paper is passing through and sends a signal to the control system. The control system sends a signal to the second motor 54441. The second motor 54441 drives the eccentric shaft 54446 to rotate through the fifth synchronous pulley 54443, the sixth synchronous pulley 54444, and the third synchronous belt 54445. The eccentric shaft 54446 drives the lower roller 5122 to rotate through the first cylindrical helical gear 5123 and the second cylindrical helical gear 5127. The lower roller 5122 drives the upper roller 5121 to rotate simultaneously through the transmission assembly 5124, conveying the folded and compacted paper forward to the output belt 554.

[0091] Meanwhile, the eccentric shaft 54446 drives the guide shaft 5442 through the first pull ring 54449 and the connecting clamp 54448 to move the right sorting plate 5441 to the left to sort the folded and compacted paper, so that the folded and compacted paper moves closer to the left plate 541 on the left side; at the same time, the eccentric shaft 54446 drives the shaft 5453 through the second pull ring 5458, the fisheye joint 5457, the round bar 5456 and the rocker arm 5455 to move the rear sorting plate 5451 forward to sort the folded and compacted paper towards the rear plate 542;

[0092] The lifting motor 5241 works by driving the sprocket drive shaft 5243 to rotate through the reducer 5242. The sprocket drive shaft 5243 drives the two lifting plates 521 to rise or fall along with the paper output mechanism 55 through the seventh sprocket 5231, the eighth sprocket 5232, and the fourth chain 5233.

[0093] When the output belt 554 is full of folded and compacted paper, the translation motor 5343 drives the lead screw 5341 to rotate via the third synchronous pulley 5345, the fourth synchronous pulley 5346, and the second synchronous belt 5347. The lead screw 5341 drives the two paper-holding fixing plates 532 to move inward with the two paper-holding plates 531 through the two lead screw nuts 5342 to receive the folded and compacted paper output from the lower roller 5122 and the upper roller 5121. Then, the output motor 555 drives the drive roller 552 to rotate via the seventh synchronous pulley 556, the eighth synchronous pulley 557, and the fourth synchronous belt 558, causing the output belt 554 to move outward and convey the folded and compacted paper.

[0094] The beneficial effects of this utility model are:

[0095] 1. After being corrected by the paper alignment conveyor, the folded paper is conveyed to the longitudinal compaction device at the folding ridge, where it is compacted. Simultaneously, the paper lifting conveyor raises the compacted paper and conveys it to the paper stacking device, which stacks the compacted paper. This invention has a simple structure, low cost, low failure rate, simple and convenient maintenance, and high production efficiency.

[0096] 2. The two compaction rollers of the compaction roller group are in complete longitudinal contact from beginning to end to compact and tighten the paper folding ridge. Therefore, the contact time between the folding ridge and the pressure roller is long and the contact area is large, so the folded part of the paper is pressed tightly and flat.

[0097] 3. When the folded parts of the folded paper are pressed tightly and flat, it is more conducive to the subsequent binding process, and the bound book is sturdy, flat and beautiful.

[0098] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
