Description

Technical Field

[0001] The invention relates to the technical field of brochure folding, and in particular to a printed brochure folding device. Background Art

[0002] In order to increase the attractiveness of brochures and facilitate carrying and mailing, brochures are usually folded. Among them, folding a brochure into a memorial shape is a creative binding method.

[0003] The device for folding a brochure once can refer to the Chinese patent application document with authorization announcement number CN219688949U, announcement date September 15, 2023, and name "A new type of printed brochure folding equipment". The telescopic rod drives the L-shaped folding part to exert force toward the middle of the brochure to fold the brochure in half. The second guide roller rotates in the opposite direction to the lower leaf conveyor roller directly above it, driving the brochure to fold, squeeze and transport it backward.

[0004] The device for performing multiple Z-folding of the brochure can be referred to Fig.11 , multiple guide rollers 1 are arranged in parallel, multiple guide rollers 2 are arranged in parallel, guide roller 1 rotates clockwise, guide roller 2 rotates counterclockwise, guide roller 2 is connected to guide roller 1, multiple vertically arranged temporary storage plates are provided on the left side of guide roller 1, multiple vertically arranged temporary storage plates are provided on the right side of guide roller 2, and a cavity for accommodating paper is opened on one side of the temporary storage plate. When folding, the paper moves down obliquely from the upper right to between the top guide roller 1 and the top guide roller 2, and the bottom end of the paper slides into the temporary storage plate at the top left. The temporary storage plate is provided with a baffle that abuts against the end of the paper. As the upper paper continues to be conveyed, the paper between the top guide roller 1 and the middle guide roller 1 bends downward, and the bent part of the paper is captured by the middle guide roller 1 and the top guide roller 2, and moves downward under the action of the guide rollers 1 and 2, completing the first Z-fold. The second folding is similar. The folded part of the paper slides into the temporary storage plate at the top right, and then the paper bends and enters between the middle guide roller 1 and the middle guide roller 2, completing the second Z-fold. After several folds, the paper is folded into a Z shape to obtain a brochure in the shape of a memorial.

[0005] With respect to the above-mentioned related technologies, as the paper is folded multiple times, the thickness of the folded part of the paper gradually increases. Since the paper is elastic, the paper that slides into the temporary storage plate is tightly attached to the surface of the temporary storage plate. In the process of the paper sliding out of the temporary storage plate, the surface of the temporary storage plate hinders the movement of the paper. During the process, the folded part of the paper may bend and deform. In addition, when the end of the paper after multiple folding is captured by the two adjacent guide rollers 1 and 2, multiple folded surfaces may be misaligned, affecting the folding quality of the device and the folding effect of the brochure. Summary of the invention

[0006] In view of this, the present invention provides a printed brochure folding device, aiming to solve the technical problems in the prior art that the paper becomes thicker after being folded multiple times and the paper has elasticity, which makes the paper tightly attached to the surface of the temporary storage board and difficult to move smoothly.

[0007] In order to solve the above technical problems, the present invention provides a printed brochure folding device, which adopts the following technical solution: a printed brochure folding device, comprising a folding machine equipped with a plurality of guide rollers 1, a plurality of guide rollers 2 and a plurality of temporary storage plates, each of which is provided with a baffle;

[0008] The baffle is connected to the temporary storage plate in a sliding manner along the left-right direction. The temporary storage plate is provided with a through groove which is vertically penetrated and extends along the left-right direction. The temporary storage plate is provided with two groups of support members which slide along the left-right direction. The support members are both provided on one side of the baffle plate close to the guide roller 1. Each group of support members is composed of a plate 1 located above the through groove and a plate 2 located below the through groove. A clamping roller 1 is provided on the plate 1, and a clamping roller 2 is provided on the plate 2. A pressure member which can make the clamping roller 1 and the clamping roller 2 have a tendency to move toward each other is provided on the support member, and a gap is left between the clamping roller 1 and the clamping roller 2 for paper to pass through.

[0009] The temporary storage plate is provided with a spacing adjustment member for controlling the sliding of the baffle plate and the two groups of support members, and can arrange the baffle plate and the two groups of support members at equal intervals.

[0010] By adopting the above technical solution, the clamping roller 1 and the clamping roller 2 cooperate to compress the paper in the temporary storage plate, reduce the influence of the paper elastic force on the thickness of the folded paper, reduce the thickness of the folded paper, and make the folded multiple layers of paper stick more closely to each other, thereby reducing the resistance of the temporary storage plate to the movement of the paper and reducing the risk of bending of the paper when it is moved out of the temporary storage plate.

[0011] Providing a spacing adjustment member is beneficial to adjusting the position of the support member, so that the clamping rollers 1 and 2 on the two groups of support members can better provide support and compression for the paper.

[0012] Optionally, the pressure member includes torsion spring 1 and torsion spring 2, and both clamping roller 1 and clamping roller 2 are connected to the support member in a hinged manner. Torsion spring 1 is arranged at the hinge axis of clamping roller 1 and applies a force to clamping roller 1 to rotate upward and is less than the gravity of clamping roller 1. Torsion spring 2 is arranged at the hinge axis of clamping roller 2 and applies a force to clamping roller 2 to rotate upward and is greater than the gravity of clamping roller 2.

[0013] By adopting the above technical solution, under the action of torsion spring 1 and torsion spring 2, clamping roller 1 and clamping roller 2 tend to approach each other. When the paper enters between clamping roller 1 and clamping roller 2, clamping roller 1 and clamping roller 2 cooperate to press the paper.

[0014] Optionally, the clamping roller 1 and the clamping roller 2 are both provided with a pressing piece, and when the paper is away from the baffle, the pressing piece can make the clamping roller 1 and the clamping roller 2 approach each other.

[0015] By adopting the above technical solution, the interval between clamping roller 1 and clamping roller 2 of the same group of clamping rollers is reduced, and the paper is compressed twice, so that the paper is easier to be captured by guide roller 1 and guide roller 2 to complete folding, which can improve the folding quality.

[0016] Optionally, a hinge rod 1 is provided between the clamping roller 1 and the plate 1, the end of the hinge rod 1 is rotatably connected to a rotating shaft, the clamping roller 1 is fixedly sleeved on the rotating shaft, the pressing member comprises a receiving groove which is opened on a side wall of the clamping roller and extends axially, a vertical plate fixedly sleeved on the rotating shaft is provided in the receiving groove, a sleeve sleeved on the rotating shaft is fixedly connected to one side of the vertical plate, a plurality of friction blocks circumferentially arranged around the rotating shaft are provided in the receiving groove, the friction blocks are hinged to the side wall of the vertical plate through a hinge rod 2, and a spring sheet is provided between each hinge rod 2 and the sleeve;

[0017] Among them, for the clamping roller 1 located on the left temporary storage plate, the hinged rod 2 located on the top thereof is inclined from top to bottom toward the baffle, the spring sheet is arranged in the acute angle area between the friction block and the sleeve, and the pressing piece in the clamping roller 2 is symmetrically arranged with the pressing piece in the clamping roller 1;

[0018] The clamping member on the left temporary storage plate and the pressing member at the corresponding position on the right temporary storage plate are symmetrically arranged.

[0019] By adopting the above technical solution, the left clamping roller 1 is subjected to less friction when rotating clockwise and can rotate normally. When rotating counterclockwise, it is affected by the friction block and the spring sheet and is difficult to rotate smoothly. At this time, as the bent portion of the paper is captured by the next guide roller 1 and guide roller 2, the paper moves toward the outside of the temporary storage plate. Since the clamping roller 1 is difficult to rotate, the friction between the paper and the clamping roller 1 causes the clamping roller 1 to move further downward. Similarly, the left clamping roller 2 is subjected to less friction when rotating counterclockwise and can rotate normally. When rotating clockwise, it is difficult to rotate smoothly. Under the action of the friction between the paper and the clamping roller 2 and the torsion spring 2, the clamping roller 2 moves further upward.

[0020] In summary, the gap between the clamping roller 1 and the clamping roller 2 of the same clamping roller group is reduced, the paper is compressed twice, the influence of the paper elastic force on the overall thickness of the multi-layer paper is reduced, and the folding quality is improved. Similarly, for the clamping roller 1 on the right side, it rotates normally counterclockwise, but it is difficult to rotate smoothly clockwise. For the clamping roller 2 on the right side, it rotates normally clockwise, but it is difficult to rotate smoothly counterclockwise. That is, in the process of moving the paper out of the temporary storage plate, the clamping roller 1 and the clamping roller 2 move closer to each other.

[0021] Optionally, the spacing adjustment member includes screw one and screw two which are located above and below the temporary storage plate respectively, screw one is passed through the top of the baffle and the top of the two plates one respectively, screw two is passed through the bottom of the two plates two respectively, screw one rotates synchronously with screw two, screw one is provided with three thread grooves one, thread groove two and thread groove three which correspond to the baffle and the two plates one respectively, and the pitch multiples of the three are 3:2:1, screw two is provided with two thread grooves two and thread groove three which correspond to the two plates two respectively.

[0022] By adopting the above technical solution, screw rod one and screw rod two are provided, and screw rod one and screw rod two rotate synchronously, so that the movement of the stopper and the two groups of support members can be synchronously adjusted.

[0023] Optionally, the ends of screw rod one and screw rod two are fixedly sleeved with worm gears, the temporary storage plate is rotatably connected to the worm, and the two worm gears are meshed with the worm.

[0024] By adopting the above technical solution and arranging a worm gear, it is convenient to control the rotation speed of screw one and screw two, thereby improving the precision of the device.

[0025] Optionally, the upper plate of the temporary storage plate is inclined from top to bottom in a direction away from the guide roller one.

[0026] Optionally, the baffle is composed of a plate three located above the temporary storage plate and a plate four located in the internal cavity of the temporary storage plate. Plate three and plate four are fixedly connected by a fixing rod. A plate five extending downward is connected to the side of plate three away from the baffle, and plate five is slidably inserted into the side wall of the through groove.

[0027] In summary, the present invention includes the following beneficial technical effects:

[0028] 1. The clamping rollers 1 and 2 cooperate to compress the paper in the temporary storage board, reduce the influence of the paper elastic force on the thickness of the folded paper, reduce the thickness of the folded paper, and make the folded multi-layer paper stick more closely to each other, thereby reducing the hindering effect of the temporary storage board on the movement of the paper and reducing the risk of bending of the paper when it is removed from the temporary storage board;

[0029] Providing a spacing adjustment member is beneficial to adjusting the position of the support member, so that the clamping rollers 1 and 2 on the two groups of support members can better provide support and compression for the paper.

[0030] 2. Under the action of torsion spring 1 and torsion spring 2, clamping roller 1 and clamping roller 2 tend to approach each other. When the paper enters between clamping roller 1 and clamping roller 2, clamping roller 1 and clamping roller 2 cooperate to press the paper.

[0031] 3. The interval between the clamping roller 1 and the clamping roller 2 of the same clamping roller group is reduced, and the paper is compressed twice, so that the paper is easier to be captured by the guide roller 1 and the guide roller 2 to complete the folding, which can improve the folding quality.

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0045] The following is combined with Figure 1 -Attached Fig.11 The present invention is described in further detail.

[0046] The embodiment of the present invention discloses a printed brochure folding device. Figures 1 to 11 A printing brochure folding device includes a folding machine 1, which is equipped with a plurality of guide rollers 1 2, a plurality of guide rollers 2 3 and a plurality of temporary storage plates 4. Each temporary storage plate 4 is provided with a baffle 5 and a compression component. The compression component is used to apply pressure to the paper in the temporary storage plate 4. Figure 2 and Fig.11 , which can make multiple layers of paper closely attached to each other, improves the situation in the prior art where the paper is closely attached to the surface of the temporary storage board 4, thereby alleviating the hindering effect of the temporary storage board 4 on the movement of the paper, reducing the risk of paper bending during the process of being removed from the temporary storage board 4, making the folded multiple layers of paper closely attached to each other, and improving the folding effect of the device.

[0047] Reference Figure 1 and Figure 2, there are three guide rollers 2, which are arranged in parallel, and the central axis line of the three guide rollers 2 is arranged from top to bottom and tilted to the left. There are three guide rollers 23, which are arranged in parallel, and the three guide rollers 23 are arranged in parallel with the three guide rollers 2. The top guide roller 23 is located on the right side of the top guide roller 2 and the middle guide roller 2 and connected to the two. The middle guide roller 23 is located on the right side of the middle guide roller 2 and the bottom guide roller and connected to the two. The bottom guide roller 23 is located on the right side of the bottom guide roller 2 and connected to it. The folding machine 1 is equipped with a driving member 10 for driving the three guide rollers 2 and the three guide rollers 23 to rotate, which will not be described in detail here.

[0048] Reference Figure 2 and Figure 3 There are four temporary storage plates 4, two temporary storage plates 4 are arranged on the left and right sides of the guide roller 1 2 and the guide roller 2 3, the two temporary storage plates 4 on the left are arranged in the interval between two adjacent guide rollers 1 2, and the two temporary storage plates 4 on the right are arranged in the interval between two adjacent guide rollers 2 3, the temporary storage plates 4 are all inclined, and the temporary storage plates 4 are inclined downward from left to right, and the temporary storage plates 4 on the left and the temporary storage plates 4 on the right are arranged symmetrically along the inclined plane. A cavity for accommodating paper is opened at one end of the temporary storage plate 4, and a baffle 5 is arranged on each temporary storage plate 4, and the baffle 5 is located at the end of the temporary storage plate 4 away from the guide roller 1 2 and the guide roller 2 3, and the baffle 5 can abut against the end of the paper to bend the part of the paper outside the end of the temporary storage plate 4.

[0049] Reference Figure 3 and Figure 6 Furthermore, the right end of the upper plate of the left temporary storage plate 4 is tilted from top to bottom to the left, and the left end of the upper plate of the right temporary storage plate 4 is tilted from top to bottom to the right. The temporary storage plate 4 is partially tilted to provide a guide for the paper, so that the paper can pass through the guide roller 1 2 and the guide roller 2 3 and enter the temporary storage plate 4.

[0050] Reference Figure 2 and Figure 3 The guide rollers are used to drive the transmission of the paper. The guide roller 12 rotates clockwise, and the guide roller 23 rotates counterclockwise. The adjacent guide rollers 12 and guide rollers 23 cooperate to capture the bottom end of the paper. The three guide rollers 12 cooperate with the three guide rollers 23 to make the paper move in a zigzag shape. Specifically, when folding, the paper moves down from the upper right to between the top guide roller 12 and the top guide roller 23, and the bottom end of the paper slides into the temporary storage plate 4 at the top of the left side. The temporary storage plate 4 is provided with a baffle 5 that abuts against the end of the paper. As the upper paper continues to be transported, the paper between the top guide roller 2 and the middle guide roller 2 bends to the lower right, and the bent part of the paper is captured by the middle guide roller 2 and the top guide roller 23, and moves downward under the action of the guide roller 12 and the guide roller 23 to complete the first Z-shaped folding.

[0051] The second fold is similar. The folded part of the paper slides into the temporary storage plate 4 at the top right side. Then the paper between the top guide roller 23 and the middle guide roller 23 bends to the lower left. The paper enters between the middle guide roller 12 and the middle guide roller 23 to complete the second Z-fold. After multiple folds, the paper is folded into a Z shape to obtain a brochure in the shape of a memorial. This device folds the paper four times. If more folds are required, the number of guide rollers 12 and 23 can be increased according to actual needs.

[0052] Reference Figures 3 to 10 The compression assembly includes a compression member 6, a pressure member 7, a spacing adjustment member 8, a pressing member 9 and a driving member 10. The compression member 6 acts on the paper, and the pressure member 7 controls the compression member 6 to make the compression member 6 compress the paper so that the folded multiple layers of paper are more closely attached. The spacing adjustment member 8 is used to adjust the positional relationship between the baffle 5 on the temporary storage board 4 and the compression member 6. In the process of the paper moving from the temporary storage board 4, the pressing member 9 can make the compression member 6 further compress the paper so that the paper can be caught by the guide roller 1 2 and the guide roller 2 3. The driving member 10 is used to drive the operation of the spacing adjustment member 8.

[0053] Reference Figure 3 and Figure 4 In order to improve the close contact between the paper and the surface of the temporary storage board 4 and improve the current situation where the surface of the temporary storage board 4 hinders the movement of the paper, the following structure is adopted: a plurality of compression members 6 are provided, and each temporary storage board 4 is provided with four compression members 6, and the four compression members 6 are arranged in parallel and spaced in the front-to-back direction. The plurality of compression members 6 on the temporary storage board 4 on the same side are arranged in parallel, and the compression members 6 on the left temporary storage board 4 and the compression members 6 on the right temporary storage board 4 are symmetrically arranged along the inclined plane. The compression members 6 on each temporary storage board 4 are arranged on the side of the baffle 5 close to the guide roller 1 2 and the guide roller 2 3, so that the paper entering the temporary storage board 4 is first compressed by the compression members 6, and then moves to abut against the baffle 5.

[0054] Taking a group of compression members 6 located on the left temporary storage plate 4 as an example, specifically, the compression member 6 includes a through groove 61, two groups of support members 62, a plurality of clamping rollers 1 63 and a plurality of clamping rollers 2 64.

[0055] Reference Figure 3 and Figure 4 The through slot 61 extends in the left-right direction, and the through slot 61 passes through the temporary storage plate 4 in the vertical direction. Figure 5 , Figure 7 and Figure 8The two groups of support members 62 are arranged in parallel in the left-right direction. The support member 62 is composed of a plate 1 621 and a plate 2 622. The plate 1 621 is located above the through slot 61, and the plate 2 622 is located below the through slot 61. The plates 1 621 and 622 provide support for the clamping roller 1 63 and the clamping roller 2 64 respectively. The use of the plate 1 621 and the plate 2 622 to form the support member 62 can avoid the situation where the middle part of the support member 62 conflicts with the paper, thereby ensuring the smooth movement of the paper.

[0056] Reference Figure 5 , Figure 7 and Figure 8 A plurality of clamping rollers 63 are connected to the plate 1 621 in a one-to-one manner, and a plurality of clamping rollers 64 are connected to the plate 2 622 in a one-to-one manner. The clamping rollers 1 63 and 2 64 cooperate to press the paper located at the through groove 61, so that the folded multi-layer paper is more closely attached to each other, thereby improving the situation in which the paper is closely attached to the surface of the temporary storage plate 4 and enhancing the folding effect of the device.

[0057] Reference Figure 5 Furthermore, the baffle plate 5 is composed of a plate three located above the temporary storage plate 4 and a plate four located in the internal cavity of the temporary storage plate 4. The plate three and the plate four are fixedly connected by a fixing rod. The side of the plate three away from the baffle plate 5 is connected to a plate five extending downward, and the plate five is slidably inserted into the side wall of the through groove 61.

[0058] Reference Figure 5 and Figure 8 Furthermore, two clamping rollers 1 63 are symmetrically arranged on the plate 1 621, and two clamping rollers 2 64 are symmetrically arranged on the plate 2 622, which can improve the stability of the device and contribute to the balance of the structure. Figure 8 It is illustrated that two clamping rollers 1 63 are connected to each plate 1 621 and two clamping rollers 2 64 are connected to each plate 2 622. Furthermore, the structure of the clamping roller 1 63 can also be changed. In actual operation, the shapes of the clamping roller 1 63 and the clamping roller 2 64 can also be adjusted according to specific needs. During the adjustment process, the balance of the device can be ensured.

[0059] Reference Figure 7 and Figure 8 In order to make the clamping roller 1 63 and the clamping roller 2 64 better press the paper, the following structure is adopted: there are multiple groups of pressure members 7, and the vertically corresponding clamping rollers 1 63 and the clamping rollers 2 64 form a group of clamping rollers. Multiple groups of pressure members 7 correspond to multiple groups of clamping rollers 1 63. The pressure members 7 make the clamping rollers 1 63 and the clamping rollers 2 64 of the same group of clamping rollers have a movement tendency to approach each other, so that the clamping rollers 1 63 and the clamping rollers 2 64 cooperate to compress the paper.

[0060] Reference Figure 7 and Figure 8Specifically, the pressure member 7 includes a torsion spring 1 71 and a torsion spring 2 72. The clamping roller 1 63 and the clamping roller 2 64 are both connected to the support member 62 in a hinged manner. Taking the clamping roller 1 63 as an example, a hinge rod 1 631 is provided between the clamping roller 1 63 and the plate 1 621. The hinge rod 1 631 is rotatably connected to the plate 1 621 through a hinge shaft. The end of the hinge rod 1 631 is rotatably connected to a rotation shaft 632. The clamping roller 1 63 is fixedly sleeved on the rotation shaft 632, and the clamping roller 1 63 and the rotation shaft 632 rotate synchronously. A torsion spring 71 is provided at the hinge shaft between the plate 621 and the clamping roller 63. The torsion spring 71 acts on the clamping roller 63. The torsion spring 71 applies an upward rotational force to the clamping roller 63. The force of the torsion spring 71 on the clamping roller 63 is smaller than the gravity exerted on the clamping roller 63, so that the resultant force exerted on the clamping roller 63 is directed downward.

[0061] Torsion spring 2 72 is provided at the hinge axis between plate 2 622 and clamping roller 2 64. Torsion spring 2 72 acts on clamping roller 2 64. Torsion spring 2 72 applies an upward rotation force to clamping roller 2 64. The force of torsion spring 2 72 on clamping roller 2 64 is greater than the gravity of clamping roller 2 64, so that the combined force of clamping roller 2 64 is upward. Under the action of torsion spring 1 71 and torsion spring 2 72, clamping roller 1 63 and clamping roller 2 64 tend to approach each other. When the paper enters between clamping roller 1 63 and clamping roller 2 64, clamping roller 1 63 and clamping roller 2 64 cooperate to press the paper.

[0062] Reference Figure 4 and Figure 5 In order to facilitate the adjustment of the position of the baffle 5 and the position of the two groups of support members 62, so as to facilitate the folding of papers of different sizes, the following structure is adopted: according to the corresponding relationship in the front-to-back direction, the multiple groups of support members 62 on the temporary storage board 4 are divided into two groups, namely the left support group and the right support group, and multiple groups of spacing adjustment members 8 are provided, and the multiple groups of spacing adjustment members 8 correspond one by one to the multiple groups of compression members 6. The spacing adjustment members 8 are used to adjust the movement of the baffle 5, the left support group and the right support group, so that the three are arranged at equal intervals in sequence to ensure uniform support for the paper, and in order to ensure the stable movement of the paper, the multiple support groups of the left support group move synchronously, and the multiple support groups of the right support group move synchronously.

[0063] Reference Figure 1 , Figure 4 and Figure 6, take a set of spacing adjustment members 8 on the left temporary storage plate 4 as an example, specifically, the spacing adjustment member 8 includes a screw rod 1 81 and a screw rod 2 82. The screw rod 1 81 is rotatably arranged above the temporary storage plate 4, and the screw rod 2 82 is rotatably arranged below the temporary storage plate 4. The screw rod 1 81 is sequentially arranged on the top of the baffle 5, the top of the left side plate 1 621, and the top of the right side plate 1 621 from left to right. The screw rod 1 81 is provided with three thread grooves 1, 2, and 3 corresponding to the baffle 5, the left side plate 1 621, and the right side plate 1 621 in sequence. The baffle 5 moves along the thread groove 1, the left side plate 1 621 moves along the thread groove 2, and the right side plate 1 621 moves along the thread groove 3. The pitch multiples of the thread grooves 1, 2, and 3 are 3:2:1, that is, the displacement ratio of the baffle 5, the left side plate 1 621, and the right side plate 1 621 is 3:2:1. The screw rod 82 is passed through the bottom of the left side plate 622 and the bottom of the right side plate 622 from left to right. The thread groove 2 and the thread groove 3 are also opened on the screw rod 82 and correspond to the left side plate 622 and the right side plate 622 respectively. The pitch ratio of the thread groove 2 and the thread groove 3 is 2:1. The left side plate 1 621 moves synchronously with the left side plate 2 622, and the right side plate 1 621 moves synchronously with the right side plate 2 622.

[0064] Reference Figure 3 , Figure 8 , Fig. 9 and Fig.10 In the process of the paper moving away from the baffle 5 and outside the end of the temporary storage plate 4, the clamping roller 1 63 and the clamping roller 2 64 further press the paper, so that the paper is easily captured by the guide roller 1 2 and the guide roller 2 3, and the following structure is adopted: there are multiple groups of clamping members 9, and the clamping members 9 are arranged in a one-to-one correspondence inside the multiple clamping rollers 1 63 and the multiple clamping rollers 2 64. For the same group of clamping rollers, the clamping members 9 in the clamping roller 1 63 and the clamping members 9 in the clamping roller 2 64 are symmetrically arranged. The clamping roller 1 63, the clamping roller 2 64 and the clamping member 9 on the left temporary storage plate 4 and the clamping roller 1 63, the clamping roller 2 64 and the clamping member 9 on the right temporary storage plate 4 are all symmetrically arranged along the inclined surface.

[0065] Reference Figure 8 , Fig. 9 and Fig.10 Taking the clamping member 9 in the clamping roller 63 on the left temporary storage plate 4 as an example, specifically, the clamping member 9 includes a receiving groove 91, a vertical plate 92, a sleeve 93, a plurality of friction blocks 94, a plurality of hinge rods 95 and a plurality of springs 96.

[0066] Reference Fig. 9 and Fig.10The receiving groove 91 is provided on the side wall of the clamping roller 1 63, and the receiving groove 91 extends along the axial direction of the clamping roller 1 63. The vertical plate 92 is provided in the receiving groove 91. Two vertical plates 92 are provided. The two vertical plates 92 are arranged in parallel along the axial direction of the rotating shaft 632. The vertical plate 92 is fixedly sleeved on the rotating shaft 632. The sleeve 93 is axially penetrated. The sleeve 93 is fixedly connected between the two vertical plates 92 and sleeved on the rotating shaft 632. The rotating shaft 632, the clamping roller 1 63, the vertical plate 92 and the sleeve 93 rotate synchronously. A plurality of friction blocks 94 are arranged along the circumference of the rotating shaft 632. The friction blocks 94 are hinged to the side wall of the vertical plate 92 through the hinge rod 2 95. A plurality of spring plates 96 correspond to the plurality of friction blocks 94 one by one. The two sides of the spring plates 96 are fixedly connected to the hinge rod 2 95 and the sleeve 93 in sequence. The hinged rod 95 is tilted. Taking the hinged rod 95 at the top as an example, the hinged rod 95 is tilted from top to bottom toward the baffle 5 , and the spring 96 is disposed in the acute angle area between the hinged rod 95 and the sleeve 93 .

[0067] Reference Figure 8 , Fig. 9 and Fig.10 For the clamping roller 1 63 on the left side, when it rotates clockwise, the friction force it encounters is small and it can rotate normally. When it rotates counterclockwise, it is affected by the friction block 94 and the spring sheet 96 and it is difficult to rotate smoothly. At this time, as the bent portion of the paper is captured by the next guide roller 1 2 and the guide roller 2 3, the paper moves toward the outside of the temporary storage plate 4. Since the clamping roller 1 63 is difficult to rotate, the friction force between the paper and the clamping roller 1 63 causes the clamping roller 1 63 to move further downward.

[0068] Similarly, for the left clamping roller 2 64, the friction force is small when it rotates counterclockwise, and it can rotate normally. When it rotates clockwise, it is difficult to rotate smoothly. Under the action of the friction between the paper and the clamping roller 2 64 and the torsion spring 2 72, the clamping roller 2 64 moves further upward. In summary, the interval between the clamping roller 1 63 and the clamping roller 2 64 of the same clamping roller group is reduced, and the paper is compressed twice, which reduces the influence of the paper elastic force on the overall thickness of the multi-layer paper and improves the folding quality.

[0069] Similarly, for the clamping roller 1 63 on the right side, it rotates normally counterclockwise, but it is difficult to rotate smoothly clockwise, and for the clamping roller 2 64 on the right side, it rotates normally clockwise, but it is difficult to rotate smoothly counterclockwise. That is, in the process of paper moving out of the temporary storage plate 4, the clamping roller 1 63 and the clamping roller 2 64 are further close to each other.

[0070] In order to facilitate the control of the synchronous rotation of multiple screws 1 81 and screws 2 82 on the same temporary storage plate 4, the following structure is adopted: the driving member 10 includes multiple worm wheels 101 and worms 102, and the multiple worm wheels 101 correspond to the multiple screws 1 81 and the multiple screws 2 82 one by one. The worm 102 is rotatably arranged on the temporary storage plate 4, and the worm 102 drives its own rotation through the external rotating driving member 10, and the multiple worm wheels 101 are all engaged with the spiral grooves on the worm 102. When the worm 102 rotates, it drives the multiple worm wheels 101 to rotate, that is, drives the rotation of the multiple screws 1 81 and the multiple screws 2 82. The use of this structure is conducive to adjusting the rotation speed of the screws 1 81 and the screws 2 82.

[0071] The implementation principle of a printed brochure folding device according to an embodiment of the present invention is as follows:

[0072] When folding, the paper moves downward from the upper right to between the top guide roller 1 2 and the top guide roller 2 3, the bottom end of the paper slides into the temporary storage plate 4 at the top left, the paper passes between the clamping roller 1 63 and the clamping roller 2 64, the end of the paper abuts against the baffle 5 in the temporary storage plate 4, as the upper paper continues to be conveyed, the length of the paper between the top guide roller 1 2 and the middle guide roller 1 2 increases, and the paper is bent to the lower right under the action of the gravity of the paper, and the bent part of the paper is captured by the middle guide roller 1 2 and the top guide roller 2 3, and moves downward under the action of the guide roller 1 2 and the guide roller 2 3, completing the first Z-folding.

[0073] The second folding is similar. The folded part of the paper slides into the temporary storage plate 4 at the top right side, and the end of the folded paper passes between the clamping roller 1 63 and the clamping roller 2 64. Under the action of the torsion spring 1 71 and the torsion spring 2 72, the clamping roller 1 63 and the clamping roller 2 64 cooperate to compress the folded paper, reduce the influence of the paper elastic force on the thickness of the folded paper, reduce the thickness of the folded paper, and make the folded multi-layer paper more closely attached, thereby reducing the hindering effect of the temporary storage plate 4 on the movement of the paper and reducing the risk of bending of the paper when it is removed from the temporary storage plate 4.

[0074] Afterwards, the paper between the top guide roller 23 and the middle guide roller 23 bends to the lower left, and the paper enters between the middle guide roller 12 and the middle guide roller 23. In the process of the paper moving out from the temporary storage plate 4 at the top on the right side, it is affected by the spring piece 96 of the friction block 94, and the rotation of the clamping roller 1 63 and the clamping roller 2 64 is restricted. Under the action of the friction force between the paper and the clamping roller 1 63 and the clamping roller 2 64, the clamping roller 1 63 and the clamping roller 2 64 move closer to each other, and the paper in the temporary storage plate 4 at the top on the right side is compressed for the second time, reducing the influence of the paper elastic force on the overall thickness of the multi-layer paper, improving the folding quality, and making the paper easier to be pulled by the middle guide roller 1 2 and the middle guide roller 2 3 to complete the second Z-folding.

[0075] Similarly, after multiple folds, the paper is folded into a Z shape to obtain a brochure in the shape of a memorial.

[0076] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0077] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
