Description

Technical Field

[0001] This utility model relates to the field of saddle stitching machine technology, specifically to an anti-deviation mechanism for saddle stitching machines. Background Technology

[0002] The anti-deviation mechanism for saddle stitching machines is a key component used to prevent paper from shifting position during the binding process. It works in concert with a positioning component, guide rollers, and an adjustment device: the positioning component precisely defines the paper's lateral reference, the guide rollers maintain the paper's flatness through symmetrical pressure, and the adjustment device flexibly adjusts the spacing according to paper specifications. This mechanism effectively solves the deviation problem caused by uneven paper thickness and variations in conveyor speed, improving saddle stitching accuracy and finished product quality. It is widely used in saddle stitching scenarios for books, albums, and other publications, adapts to various paper sizes, and is easy to install and maintain. It is an important auxiliary structure for improving the automation efficiency of saddle stitching machines.

[0003] According to a public disclosure (Publication No.: CN213413327U), a saddle stitching machine includes: a frame; a processing section located at the bottom of the frame, a conveyor section for conveying cover paper, and a feeding platform; two rotating rollers rotatably connected to the feeding platform, with a conveyor belt for conveying books wound around the two rollers; a motor coaxially fixedly connected to one of the rotating rollers; a storage basket located below the side of the feeding platform away from the frame; a slant plate hinged to the side wall of the storage basket; one end of the slant plate connected to the end of the feeding platform away from the frame; two push plates slidably connected to the slant plate along its width; and a bidirectional lead screw rotatably connected to the slant plate parallel to its width direction, passing through the two push plates, with two reverse threaded grooves of the bidirectional lead screw threadedly engaging with the two push plates respectively; and a drive assembly for driving the bidirectional lead screw to rotate on the slant plate. This application enables books to be neatly arranged during feeding and saves manpower.

[0004] In the aforementioned application, the cooperation between the bidirectional lead screw and the push plate thread assembly makes it difficult to properly position the material when it is discharged from the discharge table, resulting in the material deviating during discharge. Therefore, we propose an anti-deviation mechanism for a saddle stitching machine. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an anti-deviation mechanism for a saddle stitching machine, which solves the technical problem of material deviation during the discharge process in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides an anti-deviation mechanism for a saddle stitcher, comprising: a bracket, a material plate fixedly connected to the top of the bracket, a motor fixedly connected to the side of the material plate, a roller and a threaded rod fixedly connected to the end of the output shaft of the motor, a threaded sleeve threadedly connected to the circumferential surface of the threaded rod, a material clamping plate fixedly connected to the circumferential surface of the threaded sleeve, a pulley rotatably connected to the side of the bracket, a belt rotatably provided on the circumferential surface of the pulley rotatably connected to the side of the bracket, a second pulley rotatably connected to the side of the pulley rotatably, a belt rotatably provided on the circumferential surface of the pulley rotatably connected to the side of the pulley rotatably, a motor rotatably connected to the side of the pulley rotatably, a paging rod fixedly connected to the top of the belt rotatably, and a correction mechanism provided on the side of the belt rotatably.

[0007] The correction mechanism includes a third motor, the bottom of which is fixedly connected to the top of a bracket. A rotating wheel is fixedly connected to the end of the output shaft of the third motor. A clamping plate is fixedly connected to the top of the bracket. A displacement block is slidably connected to the side of the clamping plate. A lower plate is fixedly connected to the side of the displacement block. A support column is fixedly connected to the top of the lower plate. An upper plate is fixedly connected to the top of the support column. A clamping wheel is fixedly connected to the top of the upper plate. A connecting rod is fixedly connected to the top of the lower plate. A rotating wheel is fixedly connected to the end of the connecting rod away from the lower plate.

[0008] For example, in at least one embodiment of the present invention, an anti-deviation mechanism for a saddle stitcher is provided, which further includes: an inclined block is provided on the top of the material plate, and the circumferential surface of the roller is located at the inclined bottom of the inclined block, so that the material automatically adjusts its posture before entering the conveying area and slides along the inclined surface to the roller, thereby avoiding jamming or deviation of the material due to misalignment in the initial conveying stage and improving the smoothness and stability of the overall conveying.

[0009] The number of threaded rods is set to two and arranged in a linear array on the side of the material plate. The number of threaded sleeves is set to two and arranged in a linear array on the circumference of the threaded rods. This ensures that the material clamping plate is subjected to balanced force and moves synchronously, avoids tilting or jamming, makes the clamping force of the material clamping plate on the material more uniform, enhances the limiting effect on the material, and improves the reliability of the mechanism operation.

[0010] The number of piecing bars is set to several and arranged in a linear array on the top of belt two. The circumferential surface of the piecing bars is located on the displacement trajectory of belt one, so as to separate the material one by one and avoid multiple pages sticking together during conveying.

[0011] The clamping rollers are arranged in a linear array on the top of the upper plate. The connecting rods are arranged in two symmetrical positions along the vertical central axis of the rollers. This creates a continuous limiting and correction zone in the material conveying direction, adapting to materials of different lengths. By applying correction force evenly through multi-point contact, excessive local force can be avoided, which could lead to material deformation and ensure stable correction effect.

[0012] According to another aspect, at least one embodiment of the present invention also provides an anti-deviation mechanism for a saddle stitcher, comprising: a cutting mechanism provided at the top of the bracket, the cutting mechanism including a vertical plate, the bottom of the vertical plate being fixedly connected to the top of the bracket, a rotatable wheel being rotatably connected to the inner side of the vertical plate, a motor being fixedly connected to the side of the rotatable wheel, a locking block being fixedly connected to the side of the rotatable wheel, a fixing frame being fixedly connected to the side of the vertical plate, a cutter shaft being slidably connected to the inner side of the fixing frame, a slot block being fixedly connected to the circumferential surface of the cutter shaft, a limit block being fixedly connected to one end of the cutter shaft, a cutting blade being fixedly connected to the other end of the cutter shaft, and a transmission belt being fixedly connected to the top of the bracket.

[0013] For example, in at least one embodiment of the present invention, an anti-deviation mechanism for a saddle stitching machine is provided, which further includes: a foot post fixedly connected to the bottom of the transmission belt, and the foot post is arranged in a linear array at the bottom of the transmission belt, which can evenly distribute the weight of the transmission belt and the material above it, enhance the overall support stability, reduce vibration and shaking during operation, ensure the stability of the material position during the conveying process, and provide a stable material conveying foundation for the cutting mechanism.

[0014] The number of vertical plates is set to two, and they are symmetrical to each other along the vertical central axis of the transmission belt. The top of the transmission belt is located on the displacement trajectory of the second belt, which can provide symmetrical and stable support for the cutting mechanism, ensuring that the circumferential wheel, the cutter shaft and other components are subjected to balanced forces during operation, and avoiding unilateral offset that affects the cutting accuracy.

[0015] The side of the upright plate is provided with a sliding groove, and the side of the cutting blade is fixedly connected with a slider. The width of the slider is equal to the width of the sliding groove on the side of the upright plate, which restricts the movement trajectory of the cutting blade and makes it move stably only along the direction of the sliding groove. This avoids the cutting position deviation caused by shaking or offset during the cutting process, ensures that the depth and angle of each cut are consistent, and improves the processing accuracy.

[0016] The locking block engages inside the locking slot block, and the top of the transmission belt is located on the displacement trajectory of the cutting blade, realizing the up and down cutting action of the cutting blade, ensuring precise and efficient power transmission, and avoiding transmission slippage. The side of the cutting blade is provided with grooves, and the number of grooves is set to several and arranged linearly on the side of the cutting blade. This can reduce the contact area with the material during cutting, reduce frictional resistance and heat generation, while enhancing the sharpness of the blade, improving cutting efficiency, preventing material from sticking to the blade, ensuring a flat cutting surface, and adapting to the cutting needs of materials of different thicknesses.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] In this invention, the upper plate, clamping rollers, and inclined blocks within the correction mechanism work together to drive the rotating wheel with a three-wheeled motor, which in turn moves the lower and upper plates via connecting rods. The displacement block slides within the clamping plate to ensure stable movement, allowing for flexible fine-tuning of the clamping rollers. Several clamping rollers can accommodate materials of different widths, applying corrective force in real-time during conveying to guide misaligned materials back to the correct trajectory, preventing deviation from affecting subsequent paging, saddle stitching, and cutting accuracy. The symmetrical double-link design enhances operational stability and, in conjunction with the pre-positioning mechanism, significantly reduces the probability of material misalignment, ensuring continuous and efficient operation of the saddle stitching machine and improving product quality consistency.

[0019] In this invention, the cutting mechanism utilizes the cooperation of components such as the fixed frame, cutter shaft, and slotted blocks. A four-wheel drive motor drives a rotating wheel, which, through the engagement of the slotted blocks, propels the cutter shaft to slide stably within the fixed frame, achieving precise up-and-down movement of the cutting blade. The vertical plate groove cooperates with the cutting blade slider to ensure cutting stability. The cutting blade's multi-groove design enhances cutting efficiency and quality. A transmission belt precisely conveys materials, and the symmetrical vertical plate structure ensures accurate cutting positioning. The foot support enhances overall stability and, in conjunction with the anti-deviation mechanism, guarantees cutting accuracy, improves the integrated processing efficiency of the saddle stitching machine, reduces material loss, and increases product qualification rate.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, this invention illustrates an anti-deviation mechanism for a saddle stitcher according to an embodiment of the present invention, comprising: a support 1, a material plate 2 fixedly connected to the top of the support 1, a motor 3 fixedly connected to the side of the material plate 2, a roller 4 and a threaded rod 5 fixedly connected to the end of the output shaft of the motor 3, a threaded sleeve 6 threadedly connected to the circumferential surface of the threaded rod 5, a material clamping plate 7 fixedly connected to the circumferential surface of the threaded sleeve 6, a pulley 8 rotatably connected to the side of the support 1, a belt 9 provided on the circumferential surface of the pulley 8, a pulley 10 rotatably connected to the side of the support 1, a belt 11 provided on the circumferential surface of the pulley 10, a motor 12 fixedly connected to the side of the pulley 10, a paging rod 13 fixedly connected to the top of the belt 11, and a correction mechanism 14 provided on the side of the belt 11;

[0034] The correction mechanism 14 includes a motor 141, the bottom of which is fixedly connected to the top of the bracket 1. A rotating wheel 142 is fixedly connected to the end of the output shaft of the motor 141. A clamping plate 143 is fixedly connected to the top of the bracket 1. A displacement block 144 is slidably connected to the side of the clamping plate 143. A lower plate 145 is fixedly connected to the side of the displacement block 144. A support column 146 is fixedly connected to the top of the lower plate 145. An upper plate 147 is fixedly connected to the top of the support column 146. A clamping wheel 148 is fixedly connected to the top of the upper plate 147. A connecting rod 149 is fixedly connected to the top of the lower plate 145. A rotating wheel 142 is fixedly connected to the end of the connecting rod 149 away from the lower plate 145.

[0035] In some examples, the top of the material plate 2 is provided with a ramp 1410, and the circumferential surface of the roller 4 is located at the inclined bottom of the ramp 1410, so that the material automatically adjusts its posture before entering the conveying area and slides along the inclined surface to the roller 4, avoiding jamming or deviation of the material due to misalignment in the initial conveying stage, and improving the smoothness and stability of the overall conveying.

[0036] There are two threaded rods 5 arranged in a linear array on the side of the material plate 2. There are two threaded sleeves 6 arranged in a linear array on the circumference of the threaded rods 5. This ensures that the material clamping plate 7 is subjected to balanced force and moves synchronously, avoiding tilting or jamming. It also makes the clamping force of the material clamping plate 7 on the material more evenly distributed, enhances the limiting effect on the material, and improves the reliability of the mechanism operation.

[0037] The number of page separating rods 13 is set to several, and they are arranged in a linear array on the top of the second belt 11. The circumferential surface of the page separating rods 13 is located on the displacement trajectory of the first belt 9, so as to separate the material one by one and avoid multiple pages sticking together during conveying.

[0038] There are several clamping rollers 148 arranged in a linear array on the top of the upper plate 147. There are two connecting rods 149 arranged symmetrically along the vertical central axis of the rotating wheel 142. They can form a continuous limiting and correction area in the material conveying direction, adapt to materials of different lengths, and apply correction force evenly through multi-point contact to avoid excessive local force causing material deformation and ensure stable correction effect.

[0039] For example, such as Figures 1-5 As shown, the worker first places the material on the material plate 2, which is then guided to the roller 4 by the inclined block 1410. The motors 1-3, 2-12, and 3-141 are then started. Motor 1-3 drives the roller 4 to convey the material, while simultaneously rotating the double threaded rod 5. This causes the two threaded sleeves 6 to adjust the spacing of the material clamping plate 7, initially limiting the material to prevent deviation and preventing the material from sticking together and causing blockage. Motor 2-12 drives the pulley 2-10 and belt 2-11 to run. Several paging rods 13 on the belt 2-11 move with the belt 2-11 to paging the material conveyed by belt 1-9. After paging, the material enters the correction mechanism 14. Motor 3-141 drives the rotating wheel 142 to rotate, and through the double symmetrical connecting rod 149, the displacement block 144 slides on the clamping plate 143. Several clamping rollers 148 on the upper plate 147 correct the misaligned material in real time, guiding it back to the correct track and ensuring stable posture.

[0040] like Figures 1-5As shown, this invention illustrates an anti-deviation mechanism for a saddle stitcher according to another embodiment of the present invention, comprising: a cutting mechanism 15 disposed on the top of a support 1, the cutting mechanism 15 including a vertical plate 151, the bottom of the vertical plate 151 being fixedly connected to the top of the support 1, a rotatable wheel 152 being rotatably connected to the inner side of the vertical plate 151, a motor 153 being fixedly connected to the side of the rotatable wheel 152, a locking block 154 being fixedly connected to the side of the rotatable wheel 152, a fixing frame 155 being fixedly connected to the side of the vertical plate 151, a cutter shaft 156 being slidably connected to the inner side of the fixing frame 155, a slot block 157 being fixedly connected to the circumferential surface of the cutter shaft 156, a limit block 158 being fixedly connected to one end of the cutter shaft 156, a cutting blade 159 being fixedly connected to the other end of the cutter shaft 156, and a transmission belt 1510 being fixedly connected to the top of the support 1.

[0041] In some examples, the bottom of the conveyor belt 1510 is fixedly connected to a foot post 1511. The number of foot posts 1511 is set to several and arranged in a linear array at the bottom of the conveyor belt 1510. This can evenly distribute the weight of the conveyor belt 1510 and the material above it, enhance the overall support stability, reduce vibration and shaking during operation, ensure the stability of the material position during the conveying process, and provide a stable material conveying foundation for the cutting mechanism 15.

[0042] There are two upright plates 151, which are symmetrical to each other along the vertical central axis of the transmission belt 1510. The top of the transmission belt 1510 is located on the displacement trajectory of the second belt 11, which can provide symmetrical and stable support for the cutting mechanism 15, ensuring that the components such as the circumferential wheel 152 and the cutter shaft 156 are subjected to balanced forces during operation, and avoiding unilateral offset from affecting the cutting accuracy.

[0043] The side of the upright plate 151 is provided with a sliding groove, and the side of the cutting blade 159 is fixedly connected with a slider. The width of the slider is equal to the width of the sliding groove on the side of the upright plate 151, which restricts the movement trajectory of the cutting blade 159, so that it can only move stably along the direction of the sliding groove, avoiding the cutting position deviation caused by shaking or offset during the cutting process, ensuring that the depth and angle of each cut are consistent, and improving the processing accuracy.

[0044] The locking block 154 is engaged inside the locking slot block 157. The top of the transmission belt 1510 is located on the displacement trajectory of the cutting blade 159, realizing the up and down cutting action of the cutting blade 159, ensuring precise and efficient power transmission, and avoiding transmission slippage. The side of the cutting blade 159 is provided with grooves. The number of grooves is set to several and arranged linearly on the side of the cutting blade 159. This can reduce the contact area with the material during cutting, reduce frictional resistance and heat generation, while enhancing the sharpness of the blade, improving cutting efficiency, preventing material from sticking to the blade, ensuring a flat cutting surface, and adapting to the cutting needs of materials of different thicknesses.

[0045] For example, such as Figures 1-5As shown, the operator starts motor 153, which drives the rotary wheel 152 to rotate. The locking block 154 on its side rotates accordingly, engaging with the locking slot block 157 on the cutter shaft 156, causing the cutter shaft 156 to slide on the inner side of the fixed frame 155. The sliding groove on the side of the upright plate 151 cooperates with the slider of the cutting blade 159, restricting the vertical movement of the cutting blade 159. The transmission belt 1510 transports material to the displacement trajectory of the cutting blade 159, and the cutting blade 159 descends to complete the cutting. The groove on the blade surface reduces friction and improves cutting efficiency. This process achieves precise material cutting. Combined with the symmetrical upright plate 151 and the support column 1511, it ensures stable operation, reduces material loss, and improves processing quality.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
