Description

Technical Field

[0001] This utility model relates to the field of book processing technology, and in particular to a test paper transportation alignment and positioning device. Background Technology

[0002] In existing technologies, some clamping devices achieve clamping by applying pressure in one direction, but they neglect the posture correction requirements of paper materials during the conveying process. If the test paper is slightly tilted before entering the clamping area, it is easy to shift further during clamping, affecting the subsequent alignment and positioning accuracy. At the same time, it is difficult to balance the structural strength and motion coordination of most devices, which can easily lead to problems such as loosening of connectors and transmission jamming in high-frequency operations, resulting in high maintenance costs.

[0003] Therefore, this application provides a test paper transportation alignment and positioning device to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a test paper transportation alignment and positioning device, which aims to solve the problem that when non-conforming products are detected, the response time of its actuator is too long, which may lead to non-conforming products not being removed in time and being mixed into the process of qualified products, or causing production line stoppage.

[0005] To achieve the above objectives, this application provides the following technical solution: a test paper transportation alignment and positioning device, comprising a conveying body and a frame, wherein the conveying body is connected to the frame via a steering conveying component, and a tail conveying component is provided on the frame; The frame is equipped with a page-clamping mechanism that cooperates with the tail conveyor assembly; The page clamping mechanism includes support arms, an upper pressure component, a lower pressure component, and a No. 1 cylinder. Two sets of support arms are provided on the frame, and the free ends of the two sets of support arms are connected by a set of upper pressure components, which are curved panels. Two sets of symmetrical No. 1 uprights are installed on the frame. A connecting rod is hinged to the top of the No. 1 upright. A set of connecting plates is connected to the free ends of the two sets of connecting rods. The connecting rods are slidably connected to the connecting plates. The free ends of the connecting rods are connected to the No. 1 uprights through a reset component. Two sets of symmetrical No. 2 uprights are provided on the outer wall of the frame. A flipping rod is hinged to the free end of the No. 2 upright. A pressing component is provided on the flipping rod. The flipping rod is hinged to the connecting plate. A No. 1 cylinder is provided on the frame. The No. 1 cylinder is connected to the flipping rod.

[0006] The overall mechanism is connected by modular components such as uprights, connecting rods, and flipping rods, with a clear transmission path and reduced redundant structures. The key connection parts adopt a hinged design, which reduces wear and tear, and the core components such as springs and cylinder number one are easy to disassemble and replace, making later maintenance more convenient.

[0007] Preferably, the reset element is a spring, with one end of the spring connected to the No. 1 upright and the other end connected to the connecting rod.

[0008] The connecting rod is connected to the frame by a spring. After the clamping action is completed, it can be quickly reset by the spring force without the need for an additional drive structure, which shortens the single clamping cycle and improves the continuous operation capability of the device. During the reset process, the flipping action of the connecting plate on the No. 1 upright is stable and controllable, avoiding interference with the subsequent test papers.

[0009] Preferably, the support arm has a hole, and a protrusion is provided at the edge of the upper pressure member. The protrusion has a through hole, and the through hole is fixed to the hole by bolts and nuts.

[0010] Preferably, a limiting folding plate is provided on the frame, and the connecting plate and the limiting folding plate are slidably connected.

[0011] Preferably, the two sets of flipping rods are connected by a reinforcing rod, and the No. 1 cylinder is connected to the reinforcing rod through a connecting piece that rotates at the end.

[0012] The flipping rods are connected by reinforcing rods, which greatly improves the structural stability of the flipping assembly. The hinged design of the connecting rod and the connecting plate, and the linkage structure of the flipping rod and the connecting plate, enable the driving force of the No. 1 cylinder to be efficiently transmitted to the clamping parts, ensuring the synchronization of the upper and lower pressing parts, reducing transmission jamming, and meeting the needs of high-frequency continuous operation.

[0013] Preferably, the alignment mechanism includes a slide bar, a second cylinder, a movable plate, and a fixed plate. The slide bar is mounted on the frame and is located at the inner ring of the tail conveyor assembly. A slider is provided on the slide rod, a second cylinder is provided at the bottom of the slider, a set of sliding plates is provided at the telescopic end of the second cylinder, the sliding plates are slidably connected to the slide rod, and a set of extension plates is fixedly installed on the slide rod. A set of movable plates with a U-shaped cross section is provided on the outer wall of the extension plates through a connecting rod. A positioning plate is provided on the other end of the slide rod, and a set of L-shaped fixing plates is provided on the top surface of the positioning plate.

[0014] In summary, the technical effects and advantages of this utility model are as follows: This invention features a clamping mechanism that uses an upper pressure member (arc panel) and a lower pressure member for clamping. The arc surface structure forms a suitable pressure surface when in contact with the test paper, preventing excessive local pressure from causing paper wrinkles. Simultaneously, a cylinder drives a flipping rod to achieve the clamping action. Combined with a spring-assisted resetting mechanism, the clamping force can be flexibly adjusted, ensuring stable clamping of test papers of different thicknesses while minimizing damage to the paper material, significantly improving adaptability. The limiting folding plate not only acts as a steering platform but also covers the gap between the frame and itself, effectively preventing the test paper from getting stuck in the gap when conveyed to the clamping area, ensuring a continuous material conveying path. The design of the test paper moving upwards along the inclined surfaces of the connecting plate and the lower pressure member achieves a smooth transition between conveying and clamping actions, reducing material posture deviation and improving alignment and positioning accuracy.

[0015] This utility model, through the cooperation of various components of the alignment mechanism, drives the slide plate and extension plate to move back and forth on the slide rod under the repeated extension and retraction of the second telescopic cylinder. It controls the movable plate to push the test papers and books passing through this point laterally. During this process, the fixed plate aligns the test papers and books. Furthermore, the outward folding design at the inlet of the movable plate and the fixed plate avoids the test papers and books from colliding with the movable plate or the fixed plate, thus preventing blockage.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Reference Figure 1-6 The test paper transportation alignment and positioning device shown includes a conveyor body 100 and a frame 200. The conveyor body 100 is connected to the frame 200 through a steering conveyor assembly. A tail conveyor assembly is provided on the frame 200. When the material is delivered to the frame 200, the tail conveyor assembly delivers the material to the clamping mechanism. While the tail conveyor assembly is delivering the material, the alignment mechanism aligns the test papers. Then, the clamping mechanism clamps the qualified items so that the material can proceed to the next step.

[0021] As one embodiment of this example, the page clamping mechanism has two sets of support arms 10 on the frame 200. The free ends of the two sets of support arms 10 are connected by a set of upper pressing members 11, which are arc-shaped panels. Two sets of symmetrical first uprights 1 are installed on the frame 200. A connecting rod 2 is hinged to the top of the first upright 1. A connecting plate 3 is connected to the free end of the two sets of connecting rods 2. The other end of the connecting rod 2 is connected to the frame 200 through a spring 9 to achieve self-reset. The connecting rod 2 is hinged to the connecting plate 3. Two sets of symmetrical second uprights 4 are provided on the outer wall of the frame 200. A flipping rod 5 is hinged to the free end of the second upright 4. The two sets of flipping rods 5 are connected by a reinforcing rod 7 (to improve structural stability). A lower pressing member 6 is provided on the flipping rod 5. The flipping rod 5 is hinged to the connecting plate 3. A first cylinder 8 is provided on the frame 200. The first cylinder 8 is connected to the reinforcing rod 7 through a connecting member that rotates at the end. This controls the flipping rod 5 to flip around the hinge point with the second upright 4 as the center. This causes the connecting plate 3, which is hinged to it, to flip on the first upright 1. This provides a stable conveying channel for the test paper, so that the upper pressing member 11 and the lower pressing member 6 can clamp the test paper.

[0022] The limiting folding plate 12 provided on the frame 200 acts as a turning platform, limiting the connecting plate 3 while blocking the gap between the limiting folding plate 12 and the frame 200.

[0023] As one embodiment of this example, the alignment mechanism has a slide bar 13 mounted on the frame 200, and the slide bar 13 is located at the inner ring of the tail conveying mechanism. A slider 14 is provided on the slider 13, and a second cylinder 15 is provided at the bottom of the slider 14. A set of sliding plates 16 is provided at the telescopic end of the second cylinder 15. The sliding plates 16 are slidably connected to the slider 13, and a set of extension plates 17 are fixedly installed on the slider 13. A set of movable plates 18 with a U-shaped cross section is provided on the outer wall of the extension plates 17 through a connecting rod (the inlet and outlet of the movable plates 18 are outwardly folded to form an obtuse angle to avoid the test paper and the movable plates 18 from colliding). A positioning plate 19 is provided on another section of the slide rod 13, and a set of fixed plates 20 with an L-shaped cross section is provided on the top surface of the positioning plate 19 (the top view of the fixed plate 20 is similar to that of the movable plate 18, both being obtuse angles, and the channel between the movable plate 18 and the fixed plate 20 when viewed from above is Y-shaped).

[0024] The working principle of this utility model is as follows: The conveyor body 100 transports books and other materials backward, then the steering conveyor assembly delivers them to the frame 200. Subsequently, under the transport of the tail conveyor assembly on the frame 200, the materials pass through the alignment mechanism. The second cylinder 15 operates, causing the slide plate 16 to slide on the slide rod 13. The moving slide plate 16 then drives the extension plate 17 to perform a lateral reciprocating motion, causing the movable plate 18 on the extension plate 17 to reciprocate. A positioning plate 19 is located on the other side of the slide rod 13, and a fixed plate 20 on the positioning plate 19 remains stationary. The movement trajectory of the movable plate 18, in conjunction with the fixed plate 20… The books and exam papers are aligned and then sent to the clamping mechanism. After passing through the limiting folding plate 12, they are moved to the connecting plate 3. Under the continuous conveying of the tail conveyor, all the books and other materials leave the tail conveyor and are positioned and aligned with the corner of the limiting folding plate 12. Under normal operation, the first cylinder 8 is kept raised and pressed against the reinforcing rod 7 to fix the height of the reinforcing rod 7. The lower pressing part 6 is stabilized by the flipping rod 5, so that the lower pressing part 6 and the upper pressing part 11 form a suitable channel for the current books and exam papers. Books and exam papers entering this channel can pass through subsequent equipment to the next step of operation. When a blockage occurs on the production line, cylinder 8 drives the telescopic rod to retract, which in turn drives the flipping rod 5 to rotate counterclockwise around the junction of the flipping rod 5 and the second upright rod 4 via the reinforcing rod 7. During this process, the flipping rod 5 is hinged to the connecting plate 3, causing the connecting plate 3 to flip on the first upright rod 1 via the connecting rod 2. The free end of the connecting rod 2 is connected to the frame 200 via the spring 9 (the spring 9 improves the stability of the mechanism during operation), which increases the distance between the lower pressing part 6 and the upper pressing part 11, making it easier to quickly troubleshoot the problem.

[0025] The slider 14 on the slide rod 13 is provided in four sets. One set is used to install the second cylinder 15, and the other three sets are used to measure and adjust the position of the positioning plate 19 and the sliding distance of the slide plate 16 on the slide rod 13, so as to avoid the movable plate 18 extending too far, which would cause the belt of the tail conveyor component to deform.
