Description

Technical Field

[0001] This application relates to the field of paper mounting equipment, and in particular to a paper composite positioning device for a paper mounting machine. Background Technology

[0002] A laminating machine is a printing and packaging device that laminates base paper and face paper together. Before laminating, the base paper needs to be glued, and the face paper needs to be positioned. Face paper positioning includes front positioning and side positioning. Usually, these two positioning processes are independent, that is, side positioning is performed first, followed by front positioning.

[0003] The paper side positioning and front-end positioning are set as two separate processes, which adds an extra positioning mechanism to the machine in the direction of paper movement, making the structure bulky and inefficient. Utility Model Content

[0004] In order to simplify the paper positioning process and improve positioning efficiency and effect, this application provides a paper composite positioning device for a paper mounting machine.

[0005] The paper laminating machine paper composite positioning device provided in this application adopts the following technical solution: A paper laminating machine paper composite positioning device includes a tray for carrying face paper, base plates on both sides of the tray, and support plates fixed on the top of each base plate. The support plates are provided with a lateral positioning mechanism and a front positioning mechanism for adjusting the position of the face paper. The support plates are also provided with a first sensor for detecting the lateral position of the face paper. A bottom paper is provided below the tray, and a second sensor for detecting the lateral position of the bottom paper is provided on the support plates.

[0006] By adopting the above technical solution, the support plate supports the face paper. When the face paper moves to the support plate, the bottom paper moves below the face paper. At this time, the first sensor detects the side position of the face paper, and the second sensor detects the side position of the bottom paper. The lateral positioning mechanism adjusts the lateral position of the face paper to align the face paper and the bottom paper laterally. At the same time, the front positioning mechanism adjusts the front position of the face paper to align the front ends of the face paper and the bottom paper. This allows for rapid paper positioning and simplifies the paper positioning process. Compared with the traditional method of positioning the face paper and the bottom paper separately, the connection between the lateral positioning mechanism and the front positioning mechanism makes the positioning accuracy of the face paper and the bottom paper more accurate and the misalignment error between the face paper and the bottom paper smaller. This improves the subsequent paper processing speed and die-cutting accuracy. At the same time, the improved alignment accuracy of the face paper and the bottom paper reduces the requirements for the face paper, which does not need to be too large than the bottom paper size to meet the requirement of not exposing the bottom paper. Therefore, it can reduce costs and improve the efficiency and accuracy of paper mounting.

[0007] Optionally, the lateral positioning mechanism includes a guide rail seat mounted on the support plate, a side guide motor mounted on the guide rail seat, a lead screw rotatably connected below the guide rail seat, the lead screw being connected to the output shaft of the side guide motor via a belt, a fixed plate being mounted below the lead screw, a front-end positioning mechanism being mounted on the lower side of the fixed plate, the front-end positioning mechanism being connected to the support plate and the face paper, and a connecting member being provided between the fixed plate and the lead screw.

[0008] By adopting the above technical solution, the side guide motor drives the lead screw to rotate via a belt, and the lead screw drives the fixed plate to move via a connector. The fixed plate then drives the front positioning mechanism to move, and the front positioning mechanism drives the face paper to move along the width direction of the face paper, thereby adjusting the lateral position of the face paper so that the face paper can quickly align with the lateral position of the bottom paper. Compared with the traditional paper pushing method, this structure is less likely to cause paper deformation, thus meeting the paper's precision requirements.

[0009] Optionally, the lateral positioning mechanism includes a guide rail seat mounted on a support plate, a support plate mounted on the guide rail seat, a common sliding key shaft passing through the two support plates, a sliding key sleeve mounted on the sliding key shaft that slides only along the length of the sliding key shaft, and the sliding key sleeve is rotatably connected to the support plate, both ends of the sliding key shaft are rotatably connected to a frame, the frame is equipped with a drive motor for driving the sliding key shaft to rotate, a lead screw is rotatably connected below the guide rail seat, the lead screw is connected to the sliding key sleeve via a belt, a fixed plate is mounted below the lead screw, the front positioning mechanism is mounted on the lower side of the fixed plate, the front positioning mechanism is slidably connected to the tray and clamps the face paper, and a connecting member is provided between the fixed plate and the lead screw.

[0010] By adopting the above technical solution, the distance between the two sliding key sleeves is adjusted according to the width of the paper, thereby adjusting the range of the lateral positioning mechanism to adapt to the width of the face paper. The drive motor drives the sliding key to rotate, which in turn drives the sliding key sleeve to rotate. The sliding key sleeve drives the lead screw to rotate, and the lead screw drives the fixed plate to move through the connecting piece. The fixed plate then drives the front positioning mechanism to move, and the front positioning mechanism drives the face paper to move along the width direction of the face paper, thereby adjusting the lateral position of the face paper so that the face paper can quickly align with the lateral position of the bottom paper. Compared with the traditional paper pushing method, this structure is less likely to cause paper deformation, thus meeting the paper's precision requirements.

[0011] Optionally, the connector includes a nut seat that is threadedly connected to the lead screw, the nut seat being fixedly connected to the fixed plate, a guide rail parallel to the lead screw being fixed on the guide rail seat, and a slider being fixed on the fixed plate, the slider being slidably connected to the guide rail.

[0012] By adopting the above technical solution, the lead screw drives the nut seat to move, the nut seat drives the fixed plate to move, and the guide rail and slider provide guidance for the fixed plate, so that the fixed plate can slide smoothly.

[0013] Optionally, the front positioning mechanism includes a front guide motor disposed on the lower side of the fixed plate, a correction wheel disposed on the output shaft of the front guide motor, a connecting plate disposed on the fixed plate, a support roller disposed on the connecting plate directly below the correction wheel, and the support plate and the face paper disposed between the correction wheel and the support roller.

[0014] By adopting the above technical solution, when the face paper and the support plate are clamped by the correction roller and the support roller, the front guide motor drives the correction roller to rotate, thereby moving the face paper. By adjusting the speed of the two correction rollers, the front end position of the face paper is adjusted. The correction roller and the support roller on the two support plates apply pressure to the face paper, thereby reducing the positional misalignment during the paper positioning process and improving the positioning accuracy.

[0015] Optionally, the support roller is provided with a coaxial axle, and both ends of the axle are rotatably connected to a movable block. The movable block is slidably connected to the connecting plate, and a spring is also provided between the connecting block and the connecting plate.

[0016] By adopting the above technical solution, the spring compensates for the position of the support roller, enabling the support roller and the correction roller to clamp the face paper and the support plate. When the correction roller rotates, it can drive the face paper to move stably.

[0017] Optionally, retaining rings are abutted on both sides of the support roller, and the retaining rings are disposed on the wheel axle.

[0018] By adopting the above technical solution, the retaining ring stabilizes the position of the support roller on the axle, thereby avoiding the problem of misalignment of the face paper caused by the movement of the support roller.

[0019] Optionally, the support plate is also equipped with a third sensor for detecting the displacement of the side gauge motor.

[0020] In summary, this application includes at least one of the following beneficial technical effects: The lateral and front-end positioning of the paper are performed simultaneously, reducing the need for additional positioning mechanisms in the direction of paper movement, simplifying the paper positioning process, and improving the efficiency of paper mounting. The correction rollers and support rollers on both support plates apply pressure to the paper, thereby reducing positional misalignment during the paper positioning process and improving positioning accuracy.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a paper composite positioning device for a paper mounting machine. Example 1

[0028] Reference Figure 1 , Figure 2 and Figure 3 A paper composite positioning device for a paper mounting machine includes a tray plate 1, a face paper 11 placed on the tray plate 1, base plates 2 on both sides of the tray plate 1, and support plates 3 fixed above the two base plates 2. The support plates 3 are provided with a lateral positioning mechanism 4 and a front positioning mechanism 5 for adjusting the position of the face paper 11. The support plates 3 are also provided with a first sensor 31 for detecting the lateral position of the face paper 11. A bottom paper 12 is provided below the tray plate 1, and a second sensor 32 for detecting the lateral position of the bottom paper 12 is provided on the support plates 3.

[0029] When the face paper 1 moves to the support plate 3, the bottom paper 12 moves to the bottom of the face paper 11. At this time, the first sensor 31 detects the side position of the face paper 11 and the second sensor 32 detects the side position of the bottom paper 12. Thus, the lateral positioning mechanism 4 adjusts the lateral position of the face paper 11 so that the face paper 11 and the bottom paper 12 are laterally aligned. At the same time, the front positioning mechanism 5 adjusts the front position of the face paper 11 so that the front ends of the face paper 11 and the bottom paper 12 are aligned. Thus, lateral positioning and front positioning are performed simultaneously, and the face paper 11 and the bottom paper 12 can be quickly laminated.

[0030] The lateral positioning mechanism 4 includes a guide rail seat 41 fixed on the support plate 3. A support plate 42 is fixedly connected to the guide rail seat 41. A side guide motor 43 is fixed on the support plate 42, and the output shaft of the side guide motor 43 passes through the support plate 42. A drive wheel 44 is fixedly connected to the output shaft of the side guide motor 43. The drive wheel 44 is connected to a driven wheel 45 via a belt 46. A lead screw 47 with a coaxial axis is fixedly connected to the driven wheel 45. The lead screw 47 is located below the guide rail seat 41, and bearing seats are rotatably connected to both ends of the lead screw 47. The bearing seats are fixedly connected to the guide rail seat 41. A fixing plate 48 is provided below the lead screw 47. A front-end positioning mechanism 5 is provided on the lower side of the fixing plate 48. The front-end positioning mechanism 5 is connected to the support plate 1 and the face paper 11. A connecting piece 49 is provided between the fixing plate 48 and the lead screw 47. A third sensor 33 for detecting the displacement of the side guide motor 43 is also provided on the support plate 3.

[0031] The output shaft of the side guide motor 43 drives the drive wheel 44 to rotate. The drive wheel 44 drives the driven wheel 45 to rotate via the belt 46. The driven wheel 45 drives the lead screw 47 to rotate, thereby causing the lead screw 47 to drive the fixed plate 48 to move via the connector 49. The fixed plate 48 then drives the front positioning mechanism 5 to move. The front positioning mechanism 5 drives the face paper 11 to move along the width direction of the face paper 11, thereby adjusting the lateral position of the face paper 11 so that the face paper 11 can be quickly aligned with the lateral position of the back paper 12. After the face paper 11 and the back paper 12 are laminated, the side guide motor 43 returns to its original position and is detected by the third sensor 33, thereby ensuring that the next face paper 11 is positioned and adjusted.

[0032] The connecting member 49 includes a nut seat 491 threadedly connected to the lead screw 47. The nut seat 491 is fixedly connected to the fixed plate 48. A guide rail 492 parallel to the lead screw 47 is fixed on the guide rail seat 41, and a slider 493 is fixed on the fixed plate 48. The slider 493 is slidably connected to the guide rail 492. The lead screw 47 drives the nut seat 491 to move, and the nut seat 491 drives the fixed plate 48 to move. At the same time, the guide rail 492 and the slider 493 provide guidance for the fixed plate 48, thereby enabling the fixed plate 48 to slide smoothly.

[0033] The front-end positioning mechanism 5 includes a front guide motor 51 fixed on the lower side of the fixed plate 48. A guide wheel 52 driven by a flat key is mounted on the output shaft of the front guide motor 51. A connecting plate 53 is also fixed on the fixed plate 48. A support roller 54 is mounted on the connecting plate 53 directly below the guide wheel 52. The paper support plate 1 and the face paper 11 are located between the guide wheel 52 and the support roller 54. When the face paper 11 and the paper support plate 1 are clamped by the guide wheel 52 and the support roller 54, the front guide motor 51 drives the guide wheel 52 to rotate, thereby moving the face paper 11. By adjusting the rotation speed of the two guide wheels 52, the front end position of the face paper 11 is adjusted. Both the guide wheel 52 and the support roller 54 on the two support plates 3 apply pressure to the face paper 11, making it less prone to misalignment during paper positioning.

[0034] The support roller 54 is provided with a coaxial axle, and the support roller 54 has retaining rings abutting on both sides. The retaining rings are set on the axle, and both ends of the axle are rotatably connected to moving blocks. The moving blocks are slidably connected to the connecting plate 53, and a spring 56 is provided between the connecting blocks and the connecting plate 53 to connect the two.

[0035] Spring 56 compensates for the position of support roller 54, enabling support roller 54 and correction roller 52 to clamp the face paper 11 and support plate 1. When correction roller 52 rotates, it can drive face paper 11 to move stably. The retaining ring stabilizes the position of support roller 54 on the axle, thereby avoiding the problem of face paper 11 shifting and misalignment due to the movement of support roller 54.

[0036] The implementation principle of the paper composite positioning device of the mounting machine in this application embodiment is as follows: When the face paper 11 moves between the support roller 54 and the correction roller 52, and the bottom paper 12 moves to the second sensor 32, the first sensor 31 and the second sensor 32 respectively detect the lateral position of the face paper 11 and the bottom paper 12. At this time, the side guide motor 43 drives the lead screw 47 to rotate, adjusts the front positioning mechanism 5 to move laterally, thereby driving the support roller 54 and the correction roller 52 and the face paper 11 held by the two to move until the face paper 11 is laterally aligned with the bottom paper 12. At the same time, the front guide motor 51 drives the correction roller 52 to rotate, thereby raising the front position of the face paper 11 so that the front position of the face paper 11 is aligned with the front position of the bottom paper 12, thereby quickly positioning the face paper 11 and the bottom paper 12 for easy mounting. Example 2

[0037] Reference Figure 4 The difference from Embodiment 1 is that the lateral positioning mechanism 4 includes a sliding key assembly 6, which includes a sliding key shaft 62 that passes through two support plates 42. Both ends of the sliding key shaft 62 are rotatably connected to a frame 64 via bearings. A drive motor 61 that drives the sliding key shaft 62 to rotate is also installed on one of the frames 64. A sliding key sleeve 63 corresponding to the support plate 42 is also slidably connected to the sliding key shaft 62. The sliding key sleeve 63 is slidably connected to the sliding key shaft 62 only along the length direction of the sliding key shaft 62. At the same time, the sliding key sleeve 63 is rotatably connected to the support plate 42, and the sliding key sleeve 63 is coaxial with and fixedly connected to the drive wheel 44.

[0038] A guide shaft screw mechanism is also provided on the frame 64 to control the distance between the two support plates 42 and limit the position of the support plates 42. The guide shaft screw mechanism is a conventional technology and will not be described in detail here.

[0039] When the drive motor 61 drives the slide key shaft 62 to rotate, the slide key shaft 62 drives the slide key sleeve 63 to rotate, and at the same time the slide key sleeve 63 drives the drive wheel 44 to rotate. This achieves the effect of one drive motor 61 replacing two side guide motors 43. By driving two base plates 2 to move synchronously through one drive motor 61, the operation is simpler and the synchronization rate is higher.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
