DETAILED DESCRIPTION

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

[0027] Embodiments of the present application disclose a paper laminating positioning device of a paper laminating machine. Embodiment 1

[0028] With reference to Figure 1 , Figure 2 and Figure 3 , a paper laminating positioning device of a paper laminating machine comprises a paper supporting board 1, a face paper 11 is placed on the paper supporting board 1, base plates 2 are arranged on both sides of the paper supporting board 1, support plates 3 are fixed above the two base plates 2, lateral positioning mechanisms 4 and front end positioning mechanisms 5 for adjusting the position of the face paper 11 are arranged on the support plates 3, first sensors 31 for detecting the lateral position of the face paper 11 are arranged on the support plates 3, bottom papers 12 are arranged below the paper supporting board 1, and second sensors 32 for detecting the lateral position of the bottom papers 12 are arranged on the support plates 3.

[0029] When the face paper 1 moves to the support plates 3, the bottom papers 12 move below the face paper 11 at the same time, at this time, the first sensors 31 detect the lateral edge position of the face paper 11, and the second sensors 32 detect the lateral edge position of the bottom papers 12, thereby the lateral positioning mechanisms 4 adjust the lateral position of the face paper 11, so that the face paper 11 and the bottom papers 12 are laterally aligned, and the front end positioning mechanisms 5 adjust the front end position of the face paper 11, so that the face paper 11 and the bottom papers 12 are front end aligned, thereby the lateral positioning and the front end positioning are simultaneously performed, and the face paper 11 and the bottom papers 12 can be quickly laminated.

[0030] The lateral positioning mechanism 4 comprises a guide rail base 41 fixed on the support plate 3, a support plate 42 fixedly connected to the guide rail base 41, a side gauge motor 43 fixed on the support plate 42, and an output shaft of the side gauge motor 43 penetrating through the support plate 42, a driving wheel 44 fixedly connected to the output shaft of the side gauge motor 43, a driven wheel 45 connected to the driving wheel 44 through a belt 46, a lead screw 47 coaxially fixed to the driven wheel 45, the lead screw 47 being located below the guide rail base 41 and having two ends rotatably connected to bearing seats fixedly connected to the guide rail base 41, a fixed plate 48 provided below the lead screw 47, a front end positioning mechanism 5 provided on the lower side of the fixed plate 48 and connected to the paper supporting plate 1 and the face paper 11, and a connecting piece 49 provided between the fixed plate 48 and the lead screw 47. The support plate 3 is further provided with a third sensor 33 for detecting the displacement of the side gauge motor 43.

[0031] The output shaft of the side gauge motor 43 drives the driving wheel 44 to rotate, the driving wheel 44 drives the driven wheel 45 to rotate through the belt 46, and the driven wheel 45 drives the lead screw 47 to rotate, so that the lead screw 47 drives the fixed plate 48 to move through the connecting piece 49, and the fixed plate 48 drives the front end positioning mechanism 5 to move, and the front end positioning mechanism 5 drives the face paper 11 to move along the width direction of the face paper 11, so as to adjust the lateral position of the face paper 11, and the face paper 11 can be quickly aligned with the lateral position of the base paper 12. After the face paper 11 and the base paper 12 are laminated, the side gauge motor 43 returns to the original position, and the third sensor 33 detects the position, so as to ensure that the next face paper 11 is positioned and adjusted.

[0032] The connecting piece 49 comprises a nut base 491 threadedly connected to the lead screw 47, the nut base 491 being fixedly connected to the fixed plate 48, the guide rail base 41 being fixedly provided with a guide rail 492 parallel to the lead screw 47, and the fixed plate 48 being fixedly provided with a sliding block 493 slidably connected to the guide rail 492. The lead screw 47 drives the nut base 491 to move, the nut base 491 drives the fixed plate 48 to move, and the guide rail 492 and the sliding block 493 guide the fixed plate 48 to stably slide.

[0033] The front end positioning mechanism 5 comprises a front gauge motor 51 fixed on the lower side of the fixed plate 48, a deviation correcting wheel 52 driven by a key fixed on the output shaft of the front gauge motor 51, a connecting plate 53 fixed on the fixed plate 48, and a supporting wheel 54 provided below the deviation correcting wheel 52 on the connecting plate 53. The paper supporting plate 1 and the face paper 11 are located between the deviation correcting wheel 52 and the supporting wheel 54. When the paper supporting plate 1 and the face paper 11 are clamped by the deviation correcting wheel 52 and the supporting wheel 54, the front gauge motor 51 drives the deviation correcting wheel 52 to rotate, so as to drive the face paper 11 to move. The front end position of the face paper 11 is adjusted by adjusting the rotating speed of the two deviation correcting wheels 52. The deviation correcting wheels 52 and the supporting wheels 54 on the two support plates 3 apply pressure to the face paper 11, so that the position of the paper is not prone to be deviated during positioning.

[0034] The supporting wheel 54 is provided with a wheel shaft coaxial with the supporting wheel 54, and abutting stop rings are arranged on both sides of the supporting wheel 54. The stop rings are arranged on the wheel shaft, and moving blocks are rotatably connected to both ends of the wheel shaft. The moving blocks are slidably connected to the connecting plate 53, and springs 56 are arranged between the connecting blocks and the connecting plate 53 to connect the two.

[0035] The spring 56 compensates the position of the supporting wheel 54, so that the supporting wheel 54 and the deviation correcting wheel 52 can clamp the face paper 11 and the supporting paper 1, and when the deviation correcting wheel 52 rotates, the face paper 11 can be driven to move stably. The stop ring stabilizes the position of the supporting wheel 54 on the wheel shaft, thereby avoiding the problem of position misalignment of the face paper 11 due to the position movement of the supporting wheel 54.

[0036] The implementation principle of the paper laminating machine paper composite positioning device in the embodiment is as follows: when the face paper 11 moves to between the supporting wheel 54 and the deviation correcting wheel 52, and the base paper 12 moves to the second sensor 32, the first sensor 31 and the second sensor 32 detect the lateral positions of the face paper 11 and the base paper 12, respectively. At this time, the side gauge motor 43 drives the lead screw 47 to rotate, adjusts the horizontal movement of the front end positioning mechanism 5, thereby driving the supporting wheel 54 and the deviation correcting wheel 52 and the face paper 11 clamped by the two to move, until the face paper 11 is laterally flush with the base paper 12. At the same time, the front gauge motor 51 drives the deviation correcting wheel 52 to rotate, thereby improving the front end position of the face paper 11, so that the front end position of the face paper 11 is flush with the front end position of the base paper 12, thereby quickly positioning the face paper 11 and the base paper 12, and facilitating lamination. Embodiment 2

[0037] Reference Figure 4 The difference between the embodiment 1 and the embodiment 2 is that the lateral positioning mechanism 4 comprises a sliding key assembly 6, the sliding key assembly 6 comprises a sliding key shaft 62 penetrating through the two support plates 42, and a rack 64 is rotatably connected to both ends of the sliding key shaft 62 through a bearing. One of the racks 64 is further provided with a driving motor 61 for driving the sliding key shaft 62 to rotate. The sliding key shaft 62 is further slidably connected with a sliding key sleeve 63 corresponding to the support plate 42. The sliding key sleeve 63 is slidably connected with the sliding key shaft 62 only in the length direction of the sliding key shaft 62, and is rotatably connected with the support plate 42. The sliding key sleeve 63 is coaxial with and fixedly connected with the driving wheel 44.

[0038] A guide shaft screw mechanism is further arranged on the rack 64, which is used to control the distance between the two support plates 42 and limit the position of the support plate 42. The guide shaft screw mechanism is a conventional technology, and will not be described here.

[0039] When the driving motor 61 drives the slide key shaft 62 to rotate, the slide key shaft 62 drives the slide key sleeve 63 to rotate, and the slide key sleeve 63 drives the driving wheel 44 to rotate, thereby realizing the effect that one driving motor 61 replaces two side gauge motors 43. Two base plates 2 are driven to move synchronously by one driving motor 61, the operation is more convenient, and the synchronization rate is higher.

[0040] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
