Description

Technical Field

[0001] This utility model relates to the field of binding machinery and equipment, and in particular to a fully automatic thread-locking machine conveying device that is easy to adjust. Background Technology

[0002] Sewing machines are indispensable core equipment in the printing and binding industry, mainly used to bind collated book blocks into books using sewing. In the workflow of a fully automatic sewing machine, the feeding of paper or book blocks is the first and most critical step, and the stability of the feeding device directly determines the accuracy and efficiency of subsequent sewing processing.

[0003] Currently available fully automatic thread-locking machines typically use a pusher plate structure to push the paper on the table forward to the processing station. However, in actual production applications, due to the wide variety of book and album sizes, the width of the paper often varies. Traditional conveying devices mostly rely on manual adjustment of the baffle positions to accommodate paper of different widths. Operators need to repeatedly tighten and loosen screws and calibrate the center position, which is not only cumbersome and time-consuming, but also makes it difficult to ensure that the two baffles are strictly symmetrical about the conveyor center line after adjustment, easily leading to feed deviation.

[0004] More importantly, with the diversification of printing processes, the application of soft papers such as lightweight paper and dictionary paper is becoming increasingly widespread. Existing conveyor pushers are mostly rigid structures, applying pushing force only to the rear edge of the paper. When conveying softer or thinner papers, due to the paper's insufficient stiffness, the middle of the paper is prone to arching and deformation under the combined effect of the rearward pushing force and the frictional resistance between the paper and the table surface. Alternatively, it may curl, wrinkle, or even jam due to gravity as it sags upon leaving the table and entering the feed inlet. Current technology lacks a conveyor structure that can quickly and automatically adapt to width while effectively providing flexible auxiliary support throughout the entire process for soft papers.

[0005] Therefore, this utility model proposes a fully automatic wire-locking machine conveying device that is easy to adjust, in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing fully automatic thread-locking machine conveying device, such as the cumbersome paper width adjustment requiring repeated manual calibration, and the lack of top auxiliary support when conveying soft or thin paper, the paper is prone to arching and deformation due to pushing force or curling and wrinkling due to gravity, resulting in unstable conveying and low yield. The present invention aims to provide a fully automatic thread-locking machine conveying device with an improved structure that can effectively solve the above problems and is easy to adjust.

[0007] This utility model provides an easily adjustable fully automatic wire-locking machine conveying device, comprising: a device housing, a placement platform and a baffle fixedly installed on the device housing; and an adjustment component, a support component, and a one-way cylinder.

[0008] The adjusting component and the supporting component have a specific linkage structure. The adjusting component includes a bidirectional synchronous cylinder fixed to the bottom of the device housing. Adjusting rods are fixedly connected to the piston rod ends on both sides of the bidirectional synchronous cylinder. A sliding groove is formed on the surface of the baffle facing the placement platform. A rotating wheel is rotatably connected to the end of the adjusting rod away from the bidirectional synchronous cylinder. The rotating wheel slides into the interior of the sliding groove. The supporting component includes a pressure plate. A sliding hole is formed at one end of the pressure plate. The pressure plate is slidably sleeved on the outer wall of the adjusting rod through the sliding hole. An elastic supporting rod is fixedly installed on the top of the pressure plate. A rubber block is adhered to the inner side of the top of the supporting rod.

[0009] Furthermore, the device housing, the placement platform, the adjustment component, and the support component are combined through a specific spatial relationship. The adjustment component is installed between the device housing and the placement platform, and the bidirectional synchronous cylinder drives the adjustment rod to move to limit the width. The adjustment rod also serves as a guide rail for the movement of the pressure plate. The unidirectional cylinder is installed on the device housing, and its output end is fixedly connected to the pressure plate through a connecting block, driving the pressure plate to move axially along the adjustment rod. This, in conjunction with the elastic support rod and the rubber block, achieves flexible clamping and conveying of the paper.

[0010] Preferably, the cylinder body of the bidirectional synchronous cylinder is fixed to the inner wall of the bottom of the device housing near the placement platform by bolts, and the adjusting rod is fixedly connected to the piston rod of the bidirectional synchronous cylinder by a flange or connecting sleeve to ensure stable transmission of driving force and compact structure.

[0011] Preferably, the outer circumferential surface of the wheel is in rolling contact with the inner wall of the groove, the groove extends horizontally along the length of the baffle, and the cross-sectional shape of the groove is adapted to the cross-sectional shape of the wheel, thereby converting sliding friction into rolling friction, reducing adjustment resistance and providing end support.

[0012] Preferably, the adjustment assembly further includes a protective plate, which is fixedly installed on the outside of the placement platform, and one side of the protective plate is fixedly connected to the inner wall of the device housing by bolts. The protective plate covers the movement range of the adjustment rod, serving as a dustproof and safety protection function.

[0013] Preferably, the pressure plate has an L-shaped plate structure, the sliding hole penetrates one side wall of the pressure plate, and the bottom of the pressure plate and the upper surface of the placement platform are in clearance fit or sliding contact to ensure smooth movement.

[0014] Preferably, the support rod is an elastic metal sheet with an arc-shaped structure. One end of the support rod is fixed to the top of the pressure plate, and the other end extends in the conveying direction of the placement table and is suspended in the air, so as to adapt to paper of different thicknesses by utilizing its elastic deformation.

[0015] Preferably, the rubber block is fixed to the inner surface of the suspended end of the support rod, the bottom surface of the rubber block is higher than the bearing surface of the placement platform, and the surface of the rubber block is provided with anti-slip texture to increase the friction when in contact with the paper and prevent slipping.

[0016] Preferably, one end of the connecting block is fixedly connected to the piston rod end of the one-way cylinder by a thread, and the other end of the connecting block is fixedly connected to the side wall of the pressure plate near the two-way synchronous cylinder, so as to realize reliable power transmission.

[0017] Preferably, the device housing has a feeding port at one end away from the placement table, and the bottom surface of the feeding port is on the same horizontal plane as the upper surface of the placement table to ensure that the paper can be smoothly output.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problems of cumbersome width adjustment of the conveying device and the large size and complex structure of the equipment caused by the independent operation of the conveying guide mechanism and the width limiting mechanism. It is achieved by setting a bidirectional synchronous cylinder to drive the adjusting rods on both sides to open and close synchronously, and cleverly using the adjusting rods directly as guide rails for the movement of the pressure plate of the support component. This achieves the technical effect of automatically adapting to different paper widths, simplifying the mechanical structure and ensuring that the conveying components always automatically center with the width adjustment.

[0019] 2. This utility model, by setting an elastic support rod and a rubber block above the pressure plate, utilizes the deformation recovery force of the elastic support rod in conjunction with the high friction characteristics of the rubber block to form a flexible clamping on the upper surface of the paper during the conveying process. This solves the problem in the prior art that when conveying softer or thinner paper, simply relying on rearward pushing can easily cause the paper to arch, bend, or wrinkle due to force. It achieves the technical effects of flexible clamping from top to bottom, eliminating deformation during the conveying of soft paper, and improving conveying stability and yield.

[0020] 3. This utility model solves the problem of end sagging or wobbling of cantilevered adjusting rods when they move long distances or are subjected to force by setting a rotating wheel at the end of the adjusting rod and embedding it in the groove of the baffle to cooperate with rolling. It achieves the technical effect of converting sliding friction into rolling friction to reduce adjustment resistance, while using the groove to provide high-precision horizontal guiding support to ensure the long-term operational stability of the device.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 5This utility model provides an easily adjustable fully automatic thread-locking machine conveying device, which aims to solve the problems of cumbersome adjustment when facing different widths of paper in existing fully automatic thread-locking machine conveying devices, and the instability and low yield rate caused by paper sagging, bending or wrinkling due to gravity when conveying softer paper.

[0025] like Figure 1 and Figure 2 As shown, the main structure of the easily adjustable fully automatic thread-locking machine conveying device includes a device housing 1, a placement platform 3 fixedly installed on the top of the device housing 1, and a baffle 2 located on the rear side of the placement platform 3. The device housing 1 serves as the mounting base and outer shell of the entire device, used to house the internal drive components and provide stable support. The placement platform 3 has a flat surface and is used to carry stacks or single sheets of paper to be conveyed. The baffle 2 is vertically fixed on the device housing 1, and a horizontally extending groove 405 is provided on the side of its surface facing the placement platform 3 for guiding subsequent adjustment actions.

[0026] To achieve automated paper width adaptation and adjustment, an adjustment component 4 is installed between the device housing 1 and the placement platform 3. The adjustment component 4 uses a bidirectional synchronous cylinder 402 fixed to the bottom inner wall of the device housing 1 near the placement platform 3 as the core driving source. The cylinder body of the bidirectional synchronous cylinder 402 is firmly connected to the inside of the device housing 1 by bolts. The output ends on both sides are designed with synchronously extending and retracting piston rods. Two adjustment rods 403 are fixedly connected to the piston rod ends on both sides of the bidirectional synchronous cylinder 402 by flanges or connecting sleeves, so that the adjustment rods 403 can synchronously expand outward or retract inward in the horizontal direction under the drive of the cylinder, thereby changing the distance between the two adjustment rods 403 to match the width of different paper sizes.

[0027] To ensure stable paper transport while maintaining width adjustment, a support assembly 6 is provided above the placement platform 3. The support assembly 6 includes a pressure plate 601 that is slidably fitted onto the outer wall of the adjusting rod 403 through a sliding hole 604. Here, the adjusting rod 403 cleverly combines the dual functions of a width limiting component and a transport guide rail. An elastic support rod 602 is fixedly installed on the top surface of the pressure plate 601. A rubber block 603 is bonded to the inner side of the suspended end of the support rod 602 extending in the transport direction. The rubber block 603 and the support rod 602 cooperate to form a flexible pressing structure on the upper surface of the paper, which is used to eliminate paper arching and wrinkles during transport.

[0028] The power supply for conveying relies on a one-way cylinder 7 installed on the device housing 1. The piston rod end of the one-way cylinder 7 is fixedly connected to the side wall of the pressure plate 601 near the bidirectional synchronous cylinder 402 via a connecting block 8. The one-way cylinder 7 drives the pressure plate 601 to move the support assembly 6 along the axis of the adjusting rod 403 in a reciprocating linear motion, thereby smoothly pushing the paper on the placement table 3 towards the unloading port 5 opened at the end of the device housing 1 away from the placement table 3, thus completing the automated feeding process.

[0029] Please refer to the following carefully. Figure 2 and Figure 3 The core structure will be described in detail below: As a key component connecting the power source and the guide end, the adjusting rod 403 has a rotating wheel 404 rotatably connected to its end away from the bidirectional synchronous cylinder 402. The rotating wheel 404 is mounted on the end axis of the adjusting rod 403 through bearings or pins, and the outer diameter of the rotating wheel 404 is adapted to the groove width of the slide groove 405 opened on the surface of the baffle 2, so that the rotating wheel 404 can be embedded in the slide groove 405 and roll along the length of the slide groove 405. This rolling contact method significantly reduces the mechanical resistance during the adjustment process compared with the traditional sliding contact. At the same time, the upper and lower limit effect of the slide groove 405 on the rotating wheel 404 ensures that the adjusting rod 403 always maintains a horizontal posture when it is moved under force, preventing the adjusting rod 403 from drooping at the end due to excessive cantilever or shaking when conveying force.

[0030] Meanwhile, a protective plate 401 is also provided on the outside of the placement platform 3. The protective plate 401 is fixedly connected to the outer wall of the placement platform 3 by bolts and is fixedly connected to the inner wall of the device housing 1. The protective plate 401 has a shell-like structure that covers the outside of the moving stroke area of ​​the adjusting rod 403. When the adjusting rod 403 drives the rotating wheel 404 to move along the slide 405, the protective plate 401 can shield and protect the internal moving parts, prevent external debris from entering the adjustment mechanism and avoid accidental contact of the moving parts by the operator, which could cause injury.

[0031] Please refer to Figure 4 The pressure plate 601 in the support assembly 6 is designed as a driven component that directly cooperates with the adjusting rod 403. A through sliding hole 604 is provided on the side wall of the pressure plate 601 near the adjusting rod 403. The inner diameter of the sliding hole 604 and the outer diameter of the adjusting rod 403 are fitted together by tolerance to form a clearance fit. In the assembled state, the pressure plate 601 is directly sleeved on the outer circumference of the adjusting rod 403 through the sliding hole 604. At this time, the adjusting rod 403 acts as a linear guide for the reciprocating motion of the pressure plate 601. This structural design eliminates the need for additional conveying guide components, simplifies the overall structural volume, and ensures that when the pressure plate 601 moves with the adjusting rod 403 for width adjustment, its conveying axis always remains parallel to the adjusting rod 403 and will not deflect relative to it.

[0032] Based on the above-described embodiments, in order to further optimize the conveying stability of the fully automatic thread sewing machine for soft paper and improve the overall reliability of the operation, this utility model adopts more preferred component materials and connection details design.

[0033] Please refer to Figure 4 and Figure 5 For the core flexible pressing structure, the support rod 602 is preferably made of spring steel sheet with high resilience or high molecular elastic plastic. The root of the support rod 602 is fixed to the top plane of the pressure plate 601 by screws. Its rod body extends in an arc or oblique direction towards the paper conveying direction. This cantilever beam structure design gives the support rod 602 the ability to generate elastic deformation in the vertical direction, so that it can adapt to the height changes of stacked papers of different thicknesses.

[0034] To increase friction when in contact with paper and avoid scratching the paper surface, rubber block 603 is firmly bonded to the inner surface of the suspended end of support rod 602. Rubber block 603 is made of nitrile rubber or silicone with a high coefficient of friction and soft texture. The bottom surface of rubber block 603 is set slightly lower than the highest point of the paper to be conveyed in its natural state, or the position of rubber block 603 is higher than the bearing surface of the placement table 3 but can form an interference contact with the upper end of the paper. In this way, the elastic restoring force of support rod 602 is used to keep rubber block 603 in a slightly pressed state on the upper surface of the paper. This continuous flexible downward pressure effectively counteracts the tendency of soft paper to arch in the middle when pushed.

[0035] Regarding the details of the transmission connection of the power transmission, the connecting block 8 serves as an intermediate transmission component connecting the one-way cylinder 7 and the pressure plate 601. One end of the connecting block 8 is provided with an internal threaded hole that is tightly screwed into the external thread at the end of the piston rod of the one-way cylinder 7. The other end of the connecting block 8 is fixedly connected to the side wall of the pressure plate 601 near the bidirectional synchronous cylinder 402 by bolts. This rigid connection method ensures that the thrust of the one-way cylinder 7 can be transmitted to the pressure plate 601 without loss, and also facilitates the disassembly and replacement of the cylinder assembly during equipment maintenance.

[0036] In order to ensure that the paper can flow smoothly to the next process, the device box 1 has a rectangular through-hole 5 at the end away from the placement table 3. The bottom plane of the discharge port 5 is on the same horizontal plane as the upper surface of the placement table 3. The two are seamlessly connected by chamfering or arc transition, which eliminates the height difference in the paper conveying path and prevents the paper edge from getting stuck or curling when passing through the junction.

[0037] The working principle of this easily adjustable fully automatic wire-locking machine conveyor device is as follows: When the device receives a start signal and needs to adapt to the width of the paper to be processed, the adjustment component 4 first performs the width adaptation action. The control system sends a drive command to the bidirectional synchronous cylinder 402. The bidirectional synchronous cylinder 402 pushes the piston rods at both ends to extend outward or retract inward synchronously. Since the tail of the adjustment rod 403 is fixedly connected to the piston rod, the two adjustment rods 403 move horizontally to both sides of the baffle 2 under the drive of the piston rod. At this time, the roller 404 at the end of the adjustment rod 403 rolls along the slide groove 405 on the surface of the baffle 2. During the movement of the roller 404 in the slide groove 405, it not only provides horizontal guidance for the adjustment rod 403 to prevent the cantilever end from sagging, but also reduces the mechanical resistance during the adjustment process through rolling friction. At the same time, the protective plate 401 fixed outside the placement platform 3 provides external protection and isolation for the moving adjustment rod 403.

[0038] When the distance between the two adjusting rods 403 reaches the size that matches the width of the paper to be processed, the adjusting rods 403 immediately switch to the state of conveying guide rail. At this time, the support assembly 6 is activated to achieve stable support and conveying of the soft paper. The control system drives the one-way cylinder 7 to move. The piston rod of the one-way cylinder 7 extends outward and drives the pressure plate 601 of the support assembly 6 to move forward along the axis of the adjusting rod 403 through the connecting block 8. Since the pressure plate 601 is directly sleeved on the outer wall of the adjusting rod 403 through the sliding hole 604 on one side, the adjusting rod 403 restricts the lateral freedom of the pressure plate 601, ensuring that the pressure plate 601 remains horizontal and does not deflect during the movement.

[0039] As the pressure plate 601 pushes the paper forward, the elastic support rod 602 installed above the pressure plate 601 moves forward synchronously. The rubber block 603 located on the inner side of the top of the support rod 602 always maintains flexible contact with the upper surface of the paper to be conveyed. For softer paper, the support rod 602 uses its own elastic deformation characteristics to generate downward clamping force. Combined with the high friction surface of the rubber block 603, it effectively counteracts the arching tendency of the paper when it is pushed and the downward tendency of its own gravity. This vertical clamping conveying method ensures that the paper remains flat before entering the feed port 5, avoiding bending, wrinkling or jamming of the paper. Finally, the one-way cylinder 7 smoothly pushes the paper to the feed port 5 to complete the automatic conveying operation.

[0040] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the protection scope of the claims.
