Description

Technical Field

[0001] The utility model belongs to the technical field of large-format paper guiding mechanisms, and specifically relates to a large-format paper guiding mechanism for a page overlapping and pasting machine. Background Technique

[0002] Existing page overlapping and pasting machines can only guide small-format papers. When guiding large-format papers, due to the small distance between the paper guiding belt and the machine frame, when the previous large-format paper is guided from the paper guiding mechanism to the supporting paper board on the front side of the machine frame, the conveying mechanism arranged inside the machine frame cannot drive the conveying push board extending outside the machine frame to push the large-format paper in time. Then, the next large-format paper has been conveyed from the paper guiding mechanism to the supporting paper board on the front side of the machine frame, resulting in the two large-format papers being interleaved and affecting each other, and thus unable to push and convey the large-format papers page by page, resulting in the problem of disordered pasting. Therefore, there is an urgent need to design a large-format paper guiding mechanism for a page overlapping and pasting machine to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a large-format paper guiding mechanism for a page overlapping and pasting machine, which solves the problem that the distance between the paper guiding belt and the machine frame is too small, resulting in the inability to convey two large-format papers page by page and causing disordered pasting.

One end of each paper guiding belt penetrates into the machine frame, sequentially bypasses the corresponding tensioning wheel assembly and main guide wheel, and then extends outside the machine frame and forms a closed loop with the other end of the paper guiding belt.

[0005] A lead screw support is fixedly arranged on the inner wall of the machine frame. The lead screw support is located between the two main guide wheels. The upper end of the lead screw assembly passes through the bottom of the machine frame and the tensioning seat and is arranged on the lead screw support.

[0006] Two groups of paper pressing wheel assemblies are arranged on the outer side of the paper feeding belt, and the two groups of paper pressing wheel assemblies are connected to the frame through an adjusting bracket.

[0007] Furthermore, each group of the tensioning wheel assembly includes a first tensioning wheel, a second tensioning wheel and a third tensioning wheel that are staggered, and the first tensioning wheel and the second tensioning wheel are staggered up and down on one side of the tensioning seat through a first pin shaft, a second pin shaft is passed through the third tensioning wheel, and the second pin shaft is connected to the frame through a connecting frame, and the paper feeding belt is sequentially wound around the outside of the first tensioning wheel, the second tensioning wheel, the third tensioning wheel and the main guide wheel.

[0011] Furthermore, the fastener is a hexagon socket countersunk screw.

[0012] Beneficial effects of the utility model: the design of the paper guide seat on the outer wall of the frame in the utility model can make the bottom of the large-format paper protrude from the previous large-format paper during the transportation on the paper feeding belt, avoiding the problem that the conveying mechanism on the frame cannot convey a single page due to the overlap of the previous large-format paper and the next large-format paper, effectively improving the conveying accuracy of a single-page large-format paper to prevent the risk of sticking errors;

[0013] The design that the screw assembly drives the tensioner to move up and down allows the first tensioner wheel and the second tensioner wheel on both sides of the tensioner to move up and down with the tensioner, so as to adjust the tension of the paper feed belt and improve the efficiency of the paper feed belt in driving the large-format paper to move;

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0022] In a specific embodiment of the present invention, as Figures 1-3As shown in the figure, a large-format paper guiding mechanism for a page-set sticking machine is specifically disclosed, which includes two main guide wheels 2, two sets of tensioning wheel assemblies 3, a tensioning seat 4, and a lead screw assembly 5 arranged inside the frame 1 of the page-set sticking machine. A support plate is provided at the lower part of the front side of the frame 1, and a horizontal groove is opened above the support plate. The horizontal groove is used for the extension of the conveying plate of the conveying mechanism inside the frame 1 to drive the large-format paper to move left and right. The two main guide wheels 2 are arranged in parallel and at intervals, and a main shaft 8 is passed through them. The main shaft 8 is connected to a driving mechanism. The two sets of tensioning wheel assemblies 3 are both located below the two main guide wheels 2 and are respectively arranged on both sides of the tensioning seat 4.

[0023] A paper guiding seat 6 is provided on the outer side wall of the frame 1. The length of the paper guiding seat 6 is 400 - 480 mm, and the thickness is 10 - 20 mm. The vertical cross-section of the paper guiding seat 6 is trapezoidal. The upper part of the trapezoid is provided with a guiding surface 62 for guiding the paper and is inclined, and the lower part is provided with a vertical surface for separating the papers. The included angle between the guiding surface 62 and the vertical surface is 15 - 30°. The paper guiding seat 6 is connected to the tensioning seat 4 through fasteners. The bottom of the tensioning seat 4 is fixed to the paper guiding seat 6 through fasteners. The fasteners are internal hexagon countersunk head screws. The bottom of the tensioning seat 4 is plate-shaped. After the internal hexagon countersunk head screws pass through the plate-shaped part at the bottom of the tensioning seat 4 and pass through the frame 1, they are screwed on the side wall of the paper guiding seat 6. A through groove for the up and down movement of the internal hexagon countersunk head screws is opened on the side wall of the frame 1. Two guide grooves 61 are opened on the outer side wall of the paper guiding seat 6. A paper running belt 9 is arranged in each guide groove 61 in a matching manner. One end of each paper running belt 9 passes into the frame 1, successively bypasses the corresponding tensioning wheel assembly 3 and the main guide wheel 2, and then extends outside the frame 1 to form a closed loop with the other end of the paper running belt 9. The design of the paper guiding seat 6 on the outer side wall of the frame 1 can make the bottom of the large-format paper protrude from the previous large-format paper during the conveying process of the paper running belt, avoiding the problem that the previous large-format paper and the subsequent large-format paper overlap, resulting in the inability of the conveying mechanism on the frame 1 to convey a single page, effectively improving the conveying accuracy of a single large-format paper, and preventing the risk of sticking errors.

[0024] A lead screw support 10 is fixedly arranged on the inner wall of the frame 1. The lead screw support 10 is located between the two main guide wheels 2. The upper end of the lead screw assembly 5 passes through the bottom of the frame 1 and the tensioning seat 4 and is then passed through the lead screw support 10.

[0025] Two groups of paper pressing wheel assemblies 7 are provided on the outer side of the paper feeding belt 9, and the two groups of paper pressing wheel assemblies 7 are connected to the frame 1 through an adjusting bracket, and a paper feeding channel for large-format paper to pass is formed between the two groups of paper pressing wheel assemblies 7 and the paper feeding belt 9. The two groups of paper pressing wheel assemblies 7 are close to or away from the paper feeding belt 9 under the adjustment action of the adjusting bracket to change the size of the paper feeding channel. A fixing rod is provided on the frame 1, and the adjusting bracket includes an adjusting rod, a longitudinal bracket and two transverse brackets. One end of the adjusting rod is set on the rotating rod on the frame 1 through a connecting sleeve, and the longitudinal bracket is connected to the adjusting rod through a connecting piece. The two transverse brackets are arranged on the longitudinal bracket up and down, and the middle part thereof is connected to the shaft between the two groups of paper pressing wheel assemblies 7 through a connecting piece. Speed brakes are respectively connected to the two ends of the lower transverse bracket, and the speed brakes are made of soft material, and the lower end thereof is in contact with the frame 1. When adjusting the size of the paper feeding channel, it is only necessary to adjust the angle of the adjusting rod and the connection angle between the longitudinal bracket and the adjusting rod, so as to adjust the size of the paper feeding channel to meet the conveying requirements of a single large-format paper.

[0026] Each group of tension wheel assemblies 3 includes a first tension wheel 31, a second tension wheel 32 and a third tension wheel 33 which are staggered. The first tension wheel 31 and the second tension wheel 32 are staggered up and down on one side of the tension seat 4 through a first pin shaft 34. A second pin shaft 35 is passed through the third tension wheel 33, and the second pin shaft 35 is connected to the frame 1 through a connecting frame. The paper feeding belt 9 is sequentially wound around the outside of the first tension wheel 31, the second tension wheel 32, the third tension wheel 33 and the main guide wheel 2.

[0027] A guide plate for placing large-format paper is provided on the top of the frame 1 , and a grabbing device is provided below the guide plate. The grabbing device is used to grab a single large-format paper and move it toward the paper guide seat 6 .

[0028] Each group of paper pressing wheel assemblies 7 includes a first paper pressing wheel 71 and a second paper pressing wheel 72. The first paper pressing wheel 71 and the second paper pressing wheel 72 are arranged up and down, and the second paper pressing wheel 72 is arranged on the outside of the paper guide seat 6. The design of the second paper pressing wheel 72 being arranged on the outside of the paper guide seat 6 and being in contact with the guide surface 62 on the upper part of the paper guide seat 6 can effectively make the bottom of the large-format paper protrude from the previous large-format paper when it stops, thereby effectively separating the two large-format papers to prevent the problem of obstruction of transportation caused by the overlap of the two large-format papers.

[0029] The lead screw assembly 5 includes a lead screw 51 and an adjusting handwheel 52. The lead screw 51 is helically arranged in the tensioning seat 4 and extends out of the tensioning seat 4 at both ends. The upper end passes through the lead screw support 10 and is helically connected therewith. The lower end passes through the bottom of the frame 1 and is connected to the adjusting handwheel 52. The design that the lead screw assembly 5 drives the tensioning seat 4 to move up and down can make the first tensioning wheel 31 and the second tensioning wheel 32 on both sides of the tensioning seat 4 move up and down along with the tensioning seat 4, so as to adjust the tension of the paper feed belt 9. At the same time, it can also drive the paper guide seat 6 connected to the tensioning seat 4 to move up and down to adjust the size of the paper feed channel, and at the same time improve the efficiency of the paper feed belt 9 driving the large-format paper to move.

[0030] The working process of the present utility model:

[0031] Stacks of large-format papers are placed staggeredly on the guide plate at the top of the frame 1. The bottom of the front side of the stacks of large-format papers is in partial contact with two parts of the paper feed belts 9 outside the two main guide wheels 2. Adjust the adjusting bracket to make the first paper pressing wheel 71 and the second paper pressing wheel 72 approach the two paper feed belts 9 to adjust the size of the paper feed channel to meet the size that a large-format paper can pass through; then the driving mechanism drives the main shaft 8 to rotate to drive the two main guide wheels 2 and the two paper feed belts 9 to rotate. The bottom paper of the stacks of large-format papers moves along the two paper feed belts 9 towards the paper guide seat 6. At the same time, the gripping device below the guide plate grabs the bottom paper and continues to move it towards the paper guide seat 6. The first paper pressing wheel 71 and the two paper feed belts 9 cooperate to convey the bottom large-format paper to the second paper pressing wheel 72. The guiding surface 62 of the paper guide seat 6 raises the bottom of this large-format paper. The second paper pressing wheel 72 and the two paper feed belts 9 cooperate to convey this large-format paper to the support plate on the front side of the frame 1;

[0032] When the bottom large-format paper is conveyed and falls onto the support plate on the front side of the frame 1, when the next large-format paper moves to the second paper pressing wheel 72 according to the above steps, the guiding surface 62 of the paper guide seat 6 causes the large-format paper to be in a vertical plane. The vertical plane raises the bottom of the next large-format paper so that the next large-format paper and the previous large-format paper are staggered, thereby stratifying the two papers to avoid the influence of the staggering of the two large-format papers and the inability to push and transport the large-format papers page by page, thus causing the problem of sticking and disorder, so as to improve the conveying efficiency and sticking accuracy of the large-format papers.

[0033] The above-disclosed is only a preferred embodiment of the present utility model. Of course, it cannot be used to limit the scope of the rights of the present utility model. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
