Description

Technical Field

[0001] This utility model relates to the field of paper folding machine technology, specifically a continuous tablet box folding mechanism. Background Technology

[0002] Currently, in tablet packaging production lines, the folding and packaging of instruction manuals or other paper sheets generally employs a continuous mechanical conveying structure. This structure guides and feeds the paper sheets into the folding unit via clamping mechanisms, roller feeding mechanisms, or friction belt conveying mechanisms. One existing type of structure relies on the interaction of upper and lower rollers to achieve frictional conveying of the paper sheets. While its advantage is its simple structure, it is prone to problems such as unstable clamping, insufficient friction, or conveying deviation when the type, thickness, and size of the paper sheets vary significantly. Furthermore, because the contact area between the rollers and the paper sheets is fixed, when the edges of the paper sheets are curled, warped, or have hard folds, a jumping phenomenon occurs, affecting the positioning accuracy of the paper sheets entering the folding mechanism.

[0003] Another common structure is a track-guided chain clamping structure, where the clamping fingers on the chain and the guide rail work together to propel the paper. During long-term operation, this structure is prone to accumulated gaps or localized wear on the chain, leading to unstable clamping finger movements and causing the paper to be guided in a skewed direction. Furthermore, the guide rail structure often uses a straight groove arrangement, which provides insufficient constraint on the paper at high speeds. When the paper is light or the creases are not obvious, the paper may drift or change its posture during the guiding process, affecting the accuracy of subsequent folding actions.

[0004] In addition, to achieve continuous paper feeding, some technologies use cam-driven clamping mechanisms to make the clamping fingers move up and down. However, the clamping stroke of this type of structure is limited and the contact position is fixed, making it difficult to ensure continuous and stable feeding of paper sheets with different flexibility. When the thickness of the paper sheet changes or the friction characteristics of the paper surface are different, the clamping rhythm is prone to unevenness, resulting in the paper sheet tip shaking or fold line deviation, affecting the production cycle and the quality of boxing.

[0005] In view of this, this paper studies and improves upon the existing problems, and provides a continuous tablet box folding mechanism to solve the current problems. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0006] This invention aims to solve the technical problems commonly found in existing origami conveying structures, such as unstable paper guiding, insufficient consistency in clamping and pushing, and difficulty in adjusting the introduction angle, thereby improving the paper feeding quality and conveying continuity before origami formation.

[0007] To address this issue, this invention proposes a continuous tablet folding mechanism, the overall structure of which includes a frame, a conveyor frame, a continuous conveying assembly, and a folding forming unit. By combining a crankshaft-driven worm gear propulsion mechanism with a guide box guiding structure, the tablets can maintain a stable and smooth conveying state even under high-speed conditions.

[0008] The technical solution adopted in this utility model is as follows: a continuous tablet folding mechanism, including a frame, a conveyor frame, and a continuous conveying assembly. The folding and forming unit is arranged on the surface of the frame; the conveyor frame is located on the side of the frame and serves to drive the continuous conveying assembly; the continuous conveying assembly includes a guide box, a crankshaft, and several creepers for clamping, pushing, and guiding the paper sheets. Through the combination of the above structures, the paper sheets can achieve highly stable linear conveying before the folding process.

[0009] In a preferred embodiment, the crankshaft is further configured such that: the crankshaft includes a shaft and a plurality of crank wheels arranged on its surface, each crank wheel being distributed in a straight line along the shaft and eccentrically arranged, and evenly distributed around the outer periphery of the shaft in a circumferential direction.

[0010] Specifically, the periodic rotation of the eccentric crank wheel can drive the worm to form a stable and consistent reciprocating linear motion, thereby unifying the clamping and pushing rhythm and improving the continuity and stability of paper conveying.

[0011] In a preferred example, each crank wheel is configured to use a magnetic component, and the worm is made of a ferromagnetic material, so as to achieve the adsorption and adhesion of the crank wheels during rotation.

[0012] Specifically, the magnetic attraction structure can enhance the fit between the worm and the crankshaft during reciprocating motion, improve the accuracy of the worm's movement trajectory, and thus enhance the stability of paper clamping and propulsion.

[0013] In a preferred example, the worm is further configured such that the two sides of the worm slide against the inner wall of the guide groove, and the outer periphery of the crankshaft slides against the inner wall of the worm, thereby achieving a stable movement path for the worm through upper and lower double limiters.

[0014] Specifically, this structure can prevent the worm from swaying or deviating from its trajectory during high-speed movement, ensuring a constant linear feeding direction of the paper and improving paper feeding accuracy.

[0015] In a preferred example, the surface of the worm block is provided with a toothed structure to improve the friction between the worm block and the paper surface.

[0016] Specifically, the rack can increase the force-bearing area of ​​the paper, reducing the probability of slippage during the paper's feeding process, thereby improving the paper's clamping reliability and conveying efficiency.

[0017] In a preferred embodiment, the drive box is further configured to include a motor and a timing belt assembly for driving the upper and lower crankshafts to rotate synchronously.

[0018] Specifically, the synchronous drive structure can keep the upper and lower creep blocks advancing at the same pace, avoiding deformation, displacement or misalignment of the paper due to uneven tension, and improving the coordination of the entire conveying mechanism.

[0019] In a preferred example, the bottom of the feed trough inside the guide box has an arc-shaped transition structure that matches the peripheral motion trajectory of the worm block, providing stable guidance and limiting for the paper sheet.

[0020] Specifically, the arc transition allows the paper to form a smooth bonding path before entering the folding and forming unit, preventing the paper from jumping, curling, or changing its posture, and improving the stability of the paper's feeding posture.

[0021] In a preferred embodiment, the guide box is further configured to have a detachable connection structure with the conveyor frame, and a position adjustment component is provided to adjust the guide box's infeed angle relative to the folding forming unit.

[0022] Specifically, by introducing an angle adjustment mechanism, it is possible to make real-time adjustments based on different paper thicknesses, crease shapes, or changes in the position of the folding station, making the paper introduction more flexible and controllable, and improving the equipment's adaptability and overall folding quality.

[0023] The beneficial effects achieved by this utility model are as follows:

[0024] 1. In this utility model, by setting a material trough, a sliding guide groove, and a creep block that works in conjunction with the crankshaft rod on the inner side of the guide box, the eccentric contour of the crank wheel is used to realize the reciprocating sliding of the creep block along the sliding guide groove, so that the paper sheet forms a continuous and stable clamping and pushing effect during the conveying process.

[0025] 2. In this utility model, the continuous conveying component adopts a crankshaft structure that rotates synchronously on both the upper and lower sides, and is linked with the motor and synchronous belt group in the drive box to enable the creep block to maintain a highly consistent clamping rhythm and reciprocating stroke; at the same time, a position adjustment component is configured between the guide box and the conveyor frame, which can realize the fine adjustment of the infeed angle according to the paper feeding angle requirements of the folding forming unit.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0036] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0037] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a continuous tablet box folding mechanism.

[0038] Combination Figures 1-5 As shown, the present invention provides a continuous tablet box folding mechanism, including a frame 100, a conveyor frame 200, a continuous conveying assembly 300, and a folding forming unit 110 arranged on the surface of the frame 100.

[0039] In this embodiment, the conveyor frame 200 is fixedly installed on one side of the frame 100, and its surface is provided with a drive box 210 for driving the continuous conveying assembly 300. The drive box 210 is equipped with a motor and a synchronous belt assembly, which can drive the crankshafts 320 located on the upper and lower sides of the guide box 310 to rotate synchronously through the synchronous belt assembly after the motor outputs power, thereby enabling the continuous conveying assembly 300 to maintain a stable clamping and conveying rhythm.

[0040] The continuous conveying assembly 300 includes a guide box 310, a crankshaft 320, and several creep blocks 330. The two sides of the guide box 310 are fixedly connected to the inner side of the conveyor frame 200, and the guide box 310 is arranged at an angle towards the folding forming unit 110, so that the paper can be smoothly guided before entering the folding forming unit 110, avoiding deviation and jamming.

[0041] In this embodiment, a material groove 311 for accommodating paper sheets is provided on the inner side of the guide box 310, and the bottom of the material groove 311 has an arc-shaped transition structure. The arc-shaped transition structure matches the outer peripheral movement trajectory of the worm block 330, so that the paper sheets can conform to the transition surface during the conveying process to achieve stable guidance, reduce the lifting of the paper sheet edges or deviation caused by jumping, and improve the overall guiding stability.

[0042] The upper and lower surfaces of the guide box 310 are respectively provided with several sliding guide grooves 312 for limiting and guiding the worm block 330. The worm block 330 slides into the inner side of the sliding guide groove 312 one by one, and slides back and forth in a straight line along the direction of movement of the crankshaft 320 under the constraint of the inner wall of the sliding guide groove 312. In addition, the surface of the worm block 330 is provided with a toothed structure to improve the friction of the worm block 330 when in contact with the paper, ensuring that the paper can be stably clamped, pushed and conveyed to the folding and forming unit 110.

[0043] The crankshaft 320 is located on the upper and lower sides of the guide box 310 and is driven synchronously by a motor in the drive box 210 via a synchronous belt assembly. The crankshaft 320 includes a shaft 321 and several crank pulleys 322 arranged on the surface of the shaft 321. Each crank pulley 322 is linearly distributed along the shaft 321 and is eccentrically structured, and is evenly arranged circumferentially around the outer periphery of the shaft 321. Through this structure, the crank pulleys 322 can provide periodic cam displacement to the worm gear 330 during rotation, thereby driving the worm gear 330 to achieve reciprocating sliding motion.

[0044] In some embodiments, the crank wheel 322 is made of a magnetic material, while the worm block 330 is made of a ferromagnetic material. During rotation, the crank wheel 322 can periodically attract and release the worm block 330, allowing the worm block 330 to stably adhere to the outer periphery of the crankshaft 320 and achieve follow-up motion, thereby further ensuring the accuracy and stability of the worm block 330's motion trajectory in high-frequency reciprocating motion.

[0045] In this embodiment, the two sides of the worm block 330 slide against the inner wall of the guide groove 312, while the outer periphery of the crankshaft rod 320 slides against the inner side of the worm block 330. Through this double-limiting and double-adhesion structure, the worm block 330 can maintain a stable linear reciprocating trajectory, avoid paper deviation caused by swaying, and ensure the quality of paper conveying.

[0046] In another embodiment, the guide box 310 has a detachable mounting structure relative to the conveyor frame 200. A position adjustment component is provided between the guide box 310 and the conveyor frame 200. This position adjustment component can finely adjust the angle of the guide box 310 according to changes in the paper feeding angle or paper thickness of the folding forming unit 110. By adjusting the guide angle between the guide box 310 and the folding forming unit 110, the paper can maintain a precise angle when it is conveyed into the folding forming unit 110 by the creep block 330, improving folding accuracy and reducing folding deviation.

[0047] In this embodiment, after the paper sheet enters the feed trough 311 from the upstream station, it is stably held by the worm gear 330 driven by the crankshaft 320 and pushed along the guide box 310 under the reciprocating motion of the worm gear 330. The toothed surface of the worm gear 330 can generate moderate friction on the paper sheet surface, so that the paper sheet maintains a stable speed and straightness during the conveying process. When the paper sheet reaches the outlet position of the guide box 310, it enters the folding and forming unit 110 under the action of the inclined guide structure for folding and forming, thereby realizing a continuous, stable, and efficient process for folding and boxing tablet instructions.

[0048] In summary, by setting up a crankshaft-driven creep conveyor structure, combined with an arc-shaped material trough guide, a sliding guide groove limiter, a rack and pinion friction enhancement mechanism, and an adjustable guide box angle mechanism, the continuous tablet box folding mechanism of this utility model can achieve long-term, high-frequency, and stable paper conveying, significantly improving the continuity and adaptability of the folding forming process.
