Description

Technical Field

[0001] This utility model relates to the field of book printing conveying equipment technology, and in particular to a convergence three-way conveying device based on book printing. Background Technology

[0002] On a book printing production line, semi-finished books typically come from different printing and binding processes, such as printed pages, unbound book blocks, and covers. These need to be gathered into a single channel via conveyor systems for subsequent binding and packaging. In current book printing production lines, conveyor belts, with their continuous and stable transport characteristics, serve as a crucial link between various production processes. Semi-finished books from different printing stages (such as printing, folding, and binding preparation) are transported from their respective workstations to specific locations using conveyor belts.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: existing conveyor belts generally lack effective shielding structures on both sides, and books are very prone to deviation or even falling during transmission due to factors such as conveyor belt vibration, turning inertia, or collisions from multiple converging lines, especially at the junction of branch channels and main channels; at the same time, although some devices are equipped with side shielding, the structure is fixed and cannot be adjusted according to the thickness of the books or the stacking height; therefore, in order to address the above problems, a convergence three-way conveyor device based on book printing is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of effective shielding on both sides of the conveyor belt, which makes books prone to shifting and falling at the junction of the branch and main channels due to vibration, inertia, or collisions during transport; and the fixed side shielding structures of some devices, which cannot adapt to books of different thicknesses and stacking heights. Therefore, this invention proposes a convergence three-way conveyor device based on book printing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a three-way conveyor device for book printing, comprising a conveyor belt body, a support frame installed on the lower surface of the conveyor belt body, support plates fixedly connected to both sides of the conveyor belt body, an adjustment device provided on the upper surface of the two support plates, the adjustment device comprising several installation chambers, each of the several installation chambers being fixedly connected to the upper surface of the two support plates, a sliding rod slidably connected to the inner wall of the installation chamber, a connecting plate fixedly connected to the upper end of the several sliding rods, an L-shaped plate fixedly connected to one side of the connecting plate, several circular grooves opened on the side of the two support plates that are far apart from each other, a fixing rod fixedly connected to the side of the two L-shaped plates that are far apart from each other, an arc plate slidably connected to the arc surface of the fixing rod, an insert rod slidably inserted into the L-shaped plate, one end of the arc plate being fixedly connected to the insert rod, and the insert rod being slidably connected to the inner wall of the circular groove. The aforementioned components achieve the following effect: By incorporating an adjustable device with a sliding rod structure within the mounting compartment, operators can flexibly adjust the height of the sliding rod according to the actual height of the books being transported, thereby altering the height of the limiting structure comprised of connecting plates, L-shaped plates, etc. This design is adaptable to books of varying heights, precisely limiting their position during transport and effectively preventing book displacement due to improper height matching, ensuring the stability and smooth flow of books during the confluence transport process.

[0006] Preferably, a stop is fixedly connected to one end of the fixing rod, and the size of the insert rod matches the size of the circular groove. The effect achieved by the above components is that the stop can limit the arc-shaped plate fitted on the fixing rod, preventing the arc-shaped plate from slipping off the fixing rod due to excessive sliding, thus improving the stability of the device.

[0007] Preferably, a spring is fitted onto the arc surface of the fixing rod, with both ends of the spring fixedly connected to the stop block and the arc-shaped plate, respectively. The effect achieved by the above components is that when the insertion rod is aligned with the circular groove, the spring force will cause the arc-shaped plate to move forward on the arc surface of the fixing rod, thereby causing the insertion rod to automatically insert into the inner wall of the circular groove, improving the convenience of the device.

[0008] Preferably, both the sliding rod and the arc surface of the mounting cavity are coated with a silicone coating. The effects achieved by the above components are as follows: the silicone coating can effectively reduce the frictional resistance when the two slide, making the sliding rod adjustment process smoother and more fluid, and improving the convenience of height adjustment operation; at the same time, the wear-resistant properties of the silicone coating can reduce wear between components, extend the service life of the adjustment device, and reduce maintenance costs.

[0009] Preferably, an auxiliary device is provided on one side of each of the two support plates. The auxiliary device includes two annular blocks, each fixedly connected to one side of one of the two support plates. A circular plate is rotatably connected to the inner wall of each annular block. A long rod is rotatably connected to each of the two support plates, with both ends of the long rod fixedly connected to the two circular plates. A rotating plate is fixedly connected to the arc surface of the long rod. Several fixing grooves are formed at the end of each annular block away from the support plates. A connecting rod is fixedly connected to the end of each circular plate away from the support plates. An arc-shaped block is fixedly connected to one end of the connecting rod. A threaded rod is threaded into the arc-shaped block. A fixing block is rotatably connected to one end of the threaded rod, and the fixing block is slidably connected to the inner wall of the fixing groove. A circular shaft is fixedly connected to the other end of the threaded rod. The effects achieved by the above components are: the auxiliary device, through the linkage of the annular blocks, circular plates, long rods, and rotating plates, can flexibly adjust the angle and position of the rotating plate; the cooperation of the threaded rod with the fixing grooves and fixing blocks can fix the rotating plate at a suitable angle. During the book converging and conveying process, the rotating plate can guide books smoothly into the required placement position, improving the practicality of the device.

[0010] Preferably, a limiting rod is slidably inserted inside the arc-shaped block, and one end of the limiting rod is fixedly connected to the fixed block. The effect achieved by the above components is that the limiting rod can precisely constrain the sliding trajectory of the fixed block, preventing it from shifting or shaking when the threaded rod is rotated for adjustment.

[0011] Preferably, the circular surface of the shaft has several strip grooves, which are evenly distributed in a circumferential array on the circular surface of the shaft. The effect achieved by the above components is that the strip grooves provide the operator with a better gripping point, and the friction generated by the hand contacting the strip grooves when rotating the adjusting screw of the shaft is greater, which can effectively prevent slippage and make the adjustment operation more effortless and precise.

[0012] In summary, the beneficial effects of this utility model are as follows: 1. In this utility model, by setting an adjustment device and utilizing the sliding rod structure inside the installation compartment of the adjustment device, the operator can flexibly adjust the height of the sliding rod according to the actual height of the books being transported, thereby changing the height of the limiting structure composed of the connecting plate, L-shaped plate, etc. This design can adapt to books of different heights and specifications, accurately limiting the books during the transport process, effectively preventing the books from shifting due to improper height adaptation, and ensuring the stability and smoothness of the books in the confluence transport stage. 2. In this utility model, the auxiliary device, through the linkage of components such as the ring block, circular plate, long rod, and rotating plate, can flexibly adjust the angle and position of the rotating plate; the cooperation of the threaded rod with the fixing groove and fixing block can fix the rotating plate at a suitable angle. During the book confluence transport process, the rotating plate can be used to guide the books smoothly into the required placement position, improving the practicality of the device.

[0015] Reference Figures 1-6 As shown, this utility model provides a technical solution: a three-way conveyor device for book printing, including a conveyor belt body 1, a support frame 2 installed on the lower surface of the conveyor belt body 1, support plates fixedly connected to both sides of the conveyor belt body 1, and an adjustment device 3 provided on the upper surface of the two support plates. By setting the adjustment device 3, and utilizing the sliding rod 302 structure in the mounting compartment 301 of the adjustment device 3, the operator can flexibly adjust the height of the sliding rod 302 according to the actual height of the books being conveyed, thereby changing the height of the limiting structure composed of the connecting plate 303, L-shaped plate, etc. This design can accommodate books of different heights and specifications, precisely limiting the books during transport to effectively prevent them from shifting due to improper height matching. This ensures the stability and smoothness of the books during the confluence transport process. An auxiliary device 4 is provided on one side of each of the two support plates. The auxiliary device 4, through the linkage of components such as the ring block 401, the circular plate 402, the long rod 403, and the rotating plate 404, can flexibly adjust the angle and position of the rotating plate 404. The cooperation of the threaded rod 408 with the fixing groove 405 and the fixing block 410 can fix the rotating plate 404 at a suitable angle. During the confluence transport of books, the rotating plate 404 can be used to guide the books smoothly into the required placement position, improving the practicality of the device.

[0016] The specific settings and functions of its adjustment device 3 and auxiliary device 4 will be described in detail below.

[0017] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the adjusting device 3 includes several mounting chambers 301, each of which is fixedly connected to the upper surface of two support plates. A sliding rod 302 is slidably connected to the inner wall of each mounting chamber 301. A connecting plate 303 is fixedly connected to the upper end of each sliding rod 302. An L-shaped plate 304 is fixedly connected to one side of the connecting plate 303. Several circular grooves 305 are provided on the sides of the two support plates that are far apart from each other. A fixing rod 306 is fixedly connected to the sides of the two L-shaped plates 304 that are far apart from each other. An arc-shaped plate 307 is slidably connected to the arc surface of the fixing rod 306. A plug rod 308 is slidably inserted into the L-shaped plate 304. One end of the arc-shaped plate 307 is fixedly connected to the plug rod 308. The plug rod 308 is slidably connected to the inner wall of the circular groove 305. A stop block 309 is fixedly connected to one end of the fixing rod 306. The size of the plug rod 308 matches the size of the circular groove 305, and the stop block 309 can be fitted into the fixed groove 304. The arc-shaped plate 307 on the fixed rod 306 serves as a limit, preventing the arc-shaped plate 307 from slipping off the fixed rod 306 due to excessive sliding, thus improving the stability of the device. A spring 310 is fitted on the arc surface of the fixed rod 306. The two ends of the spring 310 are fixedly connected to the stop block 309 and the arc-shaped plate 307, respectively. When the insertion rod 308 is aligned with the circular groove 305, the elastic force of the spring 310 will drive the arc-shaped plate 307 to move forward on the arc surface of the fixed rod 306, thereby driving the insertion rod 308 to automatically insert into the inner wall of the circular groove 305, improving the convenience of the device. The arc surfaces of the sliding rod 302 and the mounting chamber 301 are coated with a silicone coating. The silicone coating can effectively reduce the frictional resistance when the two slide, making the adjustment process of the sliding rod 302 smoother and improving the convenience of height adjustment operation. At the same time, the wear-resistant properties of the silicone coating can reduce wear between components, extend the service life of the adjustment device 3, and reduce maintenance costs.

[0018] Reference Figure 5 and Figure 6As shown, specifically, the auxiliary device 4 includes two annular blocks 401, which are fixedly connected to one side of two support plates respectively. A circular plate 402 is rotatably connected to the inner wall of each annular block 401. A long rod 403 is rotatably connected to the inner walls of the two support plates, with both ends of the long rod 403 fixedly connected to the two circular plates 402 respectively. A rotating plate 404 is fixedly connected to the arc surface of the long rod 403. Several fixing grooves 405 are provided at the end of the annular block 401 away from the support plates. A connecting rod 406 is fixedly connected to the end of the circular plate 402 away from the support plates. An arc-shaped block 407 is fixedly connected to one end of the connecting rod 406. A threaded rod 408 is threaded into the arc-shaped block 407. A fixing block 410 is rotatably connected to one end of the threaded rod 408. The fixing block 410 and the fixing grooves 405... The inner wall of the screw rod 408 is slidably connected, and the other end of the screw rod 408 is fixedly connected to the round shaft 409. A limiting rod 411 is slidably inserted in the arc block 407. One end of the limiting rod 411 is fixedly connected to the fixed block 410. The limiting rod 411 can precisely constrain the sliding trajectory of the fixed block 410 to prevent it from shifting or shaking when the screw rod 408 is rotated for adjustment. The arc surface of the round shaft 409 is provided with several strip grooves 412. The strip grooves 412 are evenly distributed in a circumferential array on the arc surface of the round shaft 409. The strip grooves 412 can provide better gripping points for the operator. When the round shaft 409 is rotated to adjust the screw rod 408, the friction generated by the hand contacting the strip grooves 412 is greater, which can effectively prevent slippage and make the adjustment operation more labor-saving and precise.

[0019] The working principle is as follows: First, the arc plate 307 is pulled to move the insertion rod 308 away from the inner wall of the circular groove 305. During the sliding process of the arc plate 307, the stop block 309 on the fixed rod 306 can limit the arc plate 307 to prevent it from sliding excessively and detaching from the fixed rod 306. Then, according to the height of the books conveyed on the conveyor belt, the connecting plate 303 is pulled to move the sliding rod 302 upward in the installation chamber 301. During the movement of the connecting plate 303, the L-shaped plate 304 is moved upward. When the appropriate height is adjusted, the pulling of the arc plate 307 is released. At this time, the elastic force of the spring 310 will cause the arc plate 307 to slide forward on the arc surface of the fixed rod 306, thereby causing the insertion rod 308 to automatically insert into the inner wall of the circular groove 305, completing the height adjustment. In addition, the silicone coating on the arc surface of the slide bar 302 and the mounting chamber 301 has low friction characteristics, which makes the slide bar 302 slide more smoothly and reduces the adjustment resistance of the operator; on the other hand, the silicone coating has excellent wear resistance, which effectively reduces wear between parts.

[0020] When the angle of the rotating plate 404 needs to be adjusted, rotating the circular shaft 409 drives the threaded rod 408 to move backward. During the rotation of the circular shaft 409, the groove 412 on the arc surface of the circular shaft 409 increases the friction for the operator's fingers, making it less likely for the operator to slip. Subsequently, the threaded rod 408 drives the fixing block 410 away from the inner wall of the fixing groove 405, and then pushes the rotating plate 404 to drive the long rod 403 to rotate within the support plate. The long rod 403 drives the circular plate 402 to rotate. When a suitable angle is found, rotating the circular shaft 409 drives the threaded rod 408 to rotate. Under the constraint of the limiting rod 411, the fixing block 410 slides along the axis of the threaded rod 408, so that the fixing block 410 engages with the fixing groove 405 on the ring block 401, completing the angle adjustment. After the rotating plate 404 is fixed in the corresponding position, the guide surface of the rotating plate 404 can guide the books to change direction or align with the target position during the confluence transport, making the transport more accurate.
