Description

Technical Field

[0001] This utility model relates to the field of book processing machinery technology, specifically to a book sticker feeding and conveying mechanism. Background Technology

[0002] In the bookbinding and printing industry, the feeding and conveying of book labels is a crucial link affecting overall efficiency and quality. Traditional equipment typically uses conveyor belts or roller mechanisms to transfer separated book labels, aiming to achieve continuous and stable assembly line operations. However, with the continuous improvement of production efficiency requirements and the increasing emphasis on the flatness and integrity of finished books and periodicals, ensuring that book labels, especially thin, soft, and easily wrinkled ones, maintain precise posture and stable clamping force during feeding and conveying, and avoiding slippage, misalignment, or curling, has become a technical problem that urgently needs to be optimized and solved in this field.

[0003] In existing technologies, some conveying mechanisms attempt to clamp book stickers by adding pressure rollers or using a single belt with driven rollers. However, these solutions often suffer from limitations such as uneven clamping force or insufficient contact surface, which may lead to excessive localized force on the book stickers, causing indentations, or insufficient friction causing the book stickers to slip when the conveying speed changes. In addition, structural limitations also result in poor adaptability to book stickers of different thicknesses, inconvenient adjustments, and difficulty in ensuring that the front end of the book sticker can be smoothly and evenly fed into the clamping area at high speeds, thus restricting further improvements in the overall production speed and quality. Utility Model Content

[0004] This utility model proposes a book sticker feeding and conveying mechanism, which solves the problem in the prior art that cannot ensure that book stickers, especially thin, soft and easily wrinkled book stickers, maintain a precise posture and stable clamping force during the feeding and conveying process, resulting in slippage, misalignment or curling.

[0005] The technical solution of this utility model is implemented as follows: The book cover feeding and conveying mechanism includes a fixed base and an active guide vane belt assembly and a driven guide vane belt assembly disposed on the fixed base; The active guide vane belt assembly includes an active shaft fixed to a fixed base and an active pulley fixed to the active shaft; it also includes an active auxiliary pulley located in front of the active pulley, and an active belt is tumblingly connected to the active pulley and the active auxiliary pulley; The driven guide vane belt assembly includes a support shaft fixed to a fixed base and a driven wheel rotatably mounted on the support shaft, wherein the driven wheel is located behind the driving wheel; it also includes a driven auxiliary wheel located in front of the driven wheel and below the driving belt, and a driven belt is rolledly connected to the driven wheel and the driven auxiliary wheel, wherein the upper part of the driven belt is close to the lower part of the driving belt and moves in accordance with the movement of the driving belt; The booklet enters from the beginning between the driving belt and the driven belt and is transported by being clamped and conveyed by the driving belt and the driven belt.

[0006] Furthermore, the active guide vane belt assembly also includes a fixed shaft fixed on a fixed base and located between the active wheel and the active auxiliary wheel. A first auxiliary wheel is rotatably mounted on the fixed shaft. The first auxiliary wheel is rolled above the active belt to increase the contact area between the active belt and the active wheel.

[0007] Furthermore, the fixed shaft is provided with an active extension arm, wherein the active auxiliary wheel is rotatably mounted on the active extension arm.

[0008] Furthermore, the fixed base has an internal rotating second auxiliary wheel located below the driven wheel, and the second auxiliary wheel is tactilely connected to the driven belt.

[0009] Furthermore, the fixed base is provided with multiple rotatable guide wheels, and the driven belt is rotatably connected to the multiple guide wheels to increase the transmission contact surface.

[0010] Furthermore, the fixed base is also provided with a driven extension arm, and the driven auxiliary wheel is rotatably mounted on the driven extension arm.

[0011] Furthermore, the fixed base is provided with a support member, which is installed on the top of the driven extension arm and located inside the driven belt.

[0012] Furthermore, the top of the support member is provided with a plurality of spring plates, the top of which abuts against the driven belt so that the driving belt and the driven belt are in close contact with each other.

[0013] The beneficial effects of the technical solution provided in this application are as follows: 1. This bookplate feeding and conveying mechanism employs a dual-belt clamping and conveying system with a driving guide vane belt assembly and a driven guide vane belt assembly that fit together tightly. This design allows the bookplate to receive a large-area, uniform clamping force from the upper and lower belts at its inlet, effectively overcoming the problem of excessive local pressure caused by point or line contact in traditional mechanisms, thus preventing indentations or damage to the bookplate. Simultaneously, the synchronous movement of the driven belt, closely attached to the driving belt, ensures efficient transmission of driving force during conveying, significantly eliminating the risk of slippage and misalignment of the bookplate, and providing a reliable guarantee for the stable and precise conveying of thin and soft bookplates. 2. The bookmark feeding and conveying mechanism features an ingenious layout. The active auxiliary wheel, located in front of the drive wheel, and the driven auxiliary wheel, located in front of the driven wheel, together form a smooth wedge-shaped inlet at the clamping beginning, greatly facilitating the smooth feeding of the bookmark's front end. This structure not only enhances adaptability to bookmarks of different thicknesses and reduces the frequency and complexity of equipment adjustments, but also, because the double belts maintain stable clamping over a relatively long area, the mechanism can maintain the stability of the bookmark's posture and the accuracy of its trajectory even under high-speed operation. This fundamentally improves the conveying efficiency of the entire production line and the binding quality of the final product. Attached Figure Description

[0017] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] The core of this invention lies in providing a feeding and conveying mechanism that can stably and efficiently transport book stickers, and especially effectively protect the integrity of thin and soft book stickers. Please refer to [link / reference]. Figures 1 to 6 The entire mechanism is mounted on a fixed base 10, which serves as the basic support platform for the entire mechanism. It is typically made of precision-machined metal sheets to ensure the accuracy of the installation positions of each component and the rigidity of the overall structure.

[0019] The core transmission function of the mechanism is achieved by the active guide vane belt assembly 30. This assembly includes a drive shaft 31 driven by an external drive device (such as a motor, not shown in the figure), which is reliably fixed to the fixed base 10 via bearing seats. A drive pulley 32 is fixedly mounted on the drive shaft 31, preferably a synchronous belt pulley or a roller with a high friction surface. To ensure that the drive belt 36 is tensioned and forms an effective wrap angle, an active auxiliary pulley 35 is provided in front of the drive pulley 32 (with the book cover conveying direction as the front). The drive belt 36 is rolled and connected to the drive pulley 32 and the active auxiliary pulley 35 together. The drive belt 36 can be a rubber or polyurethane synchronous belt with an appropriate coefficient of friction on its surface.

[0020] Working in conjunction with the active guide vane belt assembly 30 is the driven guide vane belt assembly 20. This assembly includes a support shaft 21 fixed to the fixed base 10, on which a driven wheel 22 is rotatably mounted via bearings. The driven wheel 22 is positioned behind the active wheel 32. Similarly, a driven auxiliary wheel 24 is positioned in front of the driven wheel 22. A driven belt 25 is fitted and rolled together on the driven wheel 22 and the driven auxiliary wheel 24. Crucially, the upper section of the driven belt 25 is arranged to be tightly pressed against the lower section of the active belt 36, so that the driven belt 25 is driven entirely by the friction between it and the active belt 36, forming a "throat" or "wedge-shaped inlet" for holding book stickers.

[0021] The book label is conveyed as follows: The book label is introduced from the beginning of the area where the drive belt 36 and the driven belt 25 are in contact (i.e., the entrance formed by the drive auxiliary wheel 35 and the driven auxiliary wheel 24), and is then clamped between the upper and lower belts. As the drive belt 36 moves continuously, the book label is smoothly conveyed forward by friction until it is released from the end.

[0022] To significantly increase the contact wrap angle between the drive belt 36 and the drive pulley 32, and improve the efficiency and stability of power transmission, in a preferred embodiment of this invention, a fixed shaft 33 is added inside the drive guide vane belt assembly 30. The fixed shaft 33 is located between the drive pulley 32 and the drive auxiliary pulley 35, and is fixed to the fixed base 10. A first auxiliary pulley 37 is rotatably mounted on the fixed shaft 33 via bearings. The first auxiliary pulley 37 presses against and rolls onto the drive belt 36 from above, causing it to bend downwards, thereby effectively increasing the winding angle of the drive belt 36 on the drive pulley 32.

[0023] To allow for flexible adjustment of the position of the active auxiliary pulley 35 to accommodate different layout requirements or belt lengths, an active extension arm 34 is provided on the fixed shaft 33. The active auxiliary pulley 35 is rotatably mounted at the end of the active extension arm 34 via bearings. This design provides installation flexibility.

[0024] Accordingly, in the driven guide vane belt assembly 20, to optimize the path of the driven belt 25 and increase its contact with the driven pulley 22, a second auxiliary pulley 26 is rotatably arranged below the driven pulley 22 inside the fixed base 10. The second auxiliary pulley 26 rolls into contact with the inner side of the driven belt 25, forming a meandering path. Furthermore, multiple guide pulleys 27 are rotatably arranged inside the fixed base 10, and the driven belt 25 passes around these guide pulleys 27. This not only increases the transmission contact surface but also helps with belt tension and stable operation.

[0025] Similar to the design of the active side, the mounting position of the driven auxiliary wheel 24 is also adjusted by the driven extension arm 23. The driven extension arm 23 is mounted on the fixed base 10, and the driven auxiliary wheel 24 is rotatably mounted at its end.

[0026] To ensure that the upper section of the driven belt 25 can stably adhere to the driving belt 36 and provide a continuous and uniform clamping force, this invention employs a specialized elastic support structure. A support member 40 is mounted on the top of the driven extension arm 23, located inside the driven belt 25. A plurality of spring plates 41 arranged along the belt width direction are further provided on the top of the support member 40. The tips of these spring plates 41 elastically abut against the inner surface of the driven belt 25, applying a continuous upward elastic force, thereby reliably pushing the driven belt 25 to adhere to the driving belt 36.

[0027] Considering the stability when conveying wide book covers, the number of driven belts 25 and driving belts 36 in this invention can be set to at least one, preferably two, and arranged symmetrically from left to right. Correspondingly, all the cooperating components such as wheels, shafts, and arms, including driven wheel 22, second auxiliary wheel 26, driven extension arm 23, driven auxiliary wheel 24, driving auxiliary wheel 35, driving extension arm 34, and driving wheel 32, are also set to at least two sets to independently support and drive the two belts, forming two parallel clamping channels.

[0028] To further enhance the belt clamping effect and accommodate potential thickness fluctuations, this invention also includes a clamping mechanism 50. The number of clamping mechanisms 50 corresponds to the number of belts and can be arranged at the clamping points of the driven belt 25 or the driving belt 36. Each clamping mechanism 50 includes a swing arm 51 rotatably mounted on a fixed shaft 33 or a support shaft 21. A clamping wheel 52 is rotatably mounted at the end of the swing arm 51 via a bearing, and the outer edge of the clamping wheel 52 acts on the outer surface of the belt. A torsion spring 53 is connected to one side of the starting end of the swing arm 51 and is sleeved on the corresponding fixed shaft 33 or support shaft 21. The other end of the torsion spring 53 is hooked or fixed to a limiting member 54 mounted on the shaft, and the torque of the torsion spring 53 causes the swing arm 51 to drive the clamping wheel 52 to always apply a stable pressure to the belt.

[0029] To prevent the belt from shifting laterally during high-speed operation and to ensure the accuracy of the conveying trajectory, both sides of the first auxiliary wheel 37 and the second auxiliary wheel 26 of this invention are machined with raised flanges to form a guide groove, which restricts the belt to the correct running path.

[0030] Furthermore, to further optimize the centering stability of the belt, the active auxiliary pulley 35 and the driven pulley 22 of this invention are designed as convex pulleys. Specifically, the highest point of the rim is the center of the convex shape, which slopes smoothly down to both sides. This structure utilizes the tension of the belt itself to give it a tendency to automatically center towards the highest point of the pulley during operation, effectively preventing deviation.

[0031] In summary, this utility model organically combines a series of technical means, including upper and lower double belt clamping, multiple auxiliary wheels to increase the wrap angle, elastic support to provide uniform pressure, adjustable extension arm to increase layout flexibility, symmetrical multi-belt design to enhance stability, dedicated clamping mechanism for adaptive clamping, and anti-deviation side guards and convex wheel design, to form an efficient, stable, reliable and highly adaptable book sticker feeding and conveying solution, effectively overcoming the shortcomings of existing technologies.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
