Description

Technical Field

[0001] This invention belongs to the field of hot stamping machines, and particularly relates to a paper correction device for hot stamping machines. Background Technology

[0002] Hot stamping refers to the process of hot stamping electroplated aluminum foil onto the surface of a substrate under specific temperature and pressure. A hot stamping machine is the equipment used to perform this process. After the paper has been processed in the previous stage, it is fed into the hot stamping machine via a conveyor belt, robotic arm, or manually. Because hot stamping requires high precision, even slight misalignment of the paper can reduce the accuracy of the stamping. Therefore, the paper needs to be corrected before entering the hot stamping machine to ensure the precision of the hot stamping process.

[0003] In existing technologies, when correcting paper alignment, the paper is usually moved to the appropriate position by moving a pusher block. After alignment, the paper needs to be fed into the hot stamping machine by a pushing mechanism. During this process, since the paper is a flexible material, simply moving the pusher block during alignment may cause problems such as bending or folding of the paper's sides, resulting in inaccurate paper movement. The same problem exists when pushing the paper into the hot stamping machine. Summary of the Invention

[0004] This invention provides a paper correction device for a hot stamping machine to solve the problems in the prior art.

[0005] The present invention adopts the following technical solution: a paper correction device for a hot stamping machine, disposed on the front side of the feed port of the hot stamping machine, comprising:

[0006] The workbench has multiple horizontally extending first grooves on both the left and right sides, and two second grooves extending to the rear end at the front end of the workbench.

[0007] Multiple first baffles, each located in a multiple first tank, are connected together by a pressure plate at their tops on the same side of the worktable.

[0008] A first slider is provided above each pressure plate, and the two first sliders are at the same height. An adjustment component is provided between each first slider and the corresponding pressure plate to adjust the height distance between them.

[0009] The bidirectional adjustment assembly on the worktable is used to drive the two first sliders to move toward each other;

[0010] Two second baffles are respectively installed in the two second tanks;

[0011] And a stretching mechanism located below the workbench, which can pull two second baffles to move towards the rear end of the workbench and upwards in the corresponding second grooves.

[0012] Multiple first baffles can move the paper by moving it inwards towards the worktable and correct any slight deviations in the paper, ultimately centering the paper in the length direction of the worktable and correcting the paper's skewness.

[0013] Furthermore, the multiple first baffles at each pressure plate are located at the outer end below the pressure plate.

[0014] Furthermore, each set of adjustable distance components includes two first linear drive sources, both of which are longitudinally mounted at the lower end of the corresponding first slider, and the output shafts of both first linear drive sources are fixedly connected to the corresponding pressure plate.

[0015] The first linear drive source drives the pressure plate to descend. With the two pressure plates in a limiting position, the paper can be prevented from being bent significantly during the pushing process, thus affecting the paper's conveyance to the feed port.

[0016] Furthermore, the bidirectional adjustment component includes;

[0017] Two side plates are respectively located at the left and right ends of the workbench;

[0018] And two first guide rods are provided between the two side plates. Both first guide rods are arranged horizontally, and the two ends of each first guide rod are fixedly connected to the two side plates respectively. Each first slider is provided with two first guide holes that slide and cooperate with the two first guide rods respectively.

[0019] Furthermore, the bidirectional adjustment component also includes:

[0020] The bearing housing is located on the inner side of the left side plate;

[0021] The lead screw is mounted on the bearing housing. The threads at both ends of the lead screw are in opposite directions. A rotating hole is provided on the right side plate. The right end of the lead screw is rotatably disposed in the rotating hole. The two first sliders are respectively provided with threaded holes that are threaded to the two ends of the lead screw.

[0022] Motor bracket located on the outer side of the right side panel;

[0023] And a rotary drive mounted on a motor bracket, the output shaft of which is connected to the end of a lead screw via a coupling.

[0024] Furthermore, the stretching mechanism includes:

[0025] A first rectangular block is installed under the workbench. The first rectangular block is located between two second baffles. The lower end face of the first rectangular block is set as a first inclined surface that extends upward from its front side to its rear side.

[0026] A second rectangular block is connected to the lower ends of the two second baffles, and the top of the second rectangular block is provided with a second inclined surface that matches the first inclined surface;

[0027] The second slider is located directly below the second rectangular block, and the second slider and the second rectangular block are elastically connected together by an elastic component.

[0028] And a linear drive assembly located below the worktable, the linear drive assembly being used to drive the second slider to move laterally.

[0029] The combination of the stretching mechanism and the two second baffles prevents the paper from being blocked when it is placed on the worktable. At the same time, the stretching mechanism can also move the two second baffles diagonally upwards during operation, so that the second baffles can push the paper towards the hot stamping machine.

[0030] Furthermore, the linear drive component includes:

[0031] A right-angle plate is provided below the workbench. Two sets of linear guides are provided on the horizontal end of the right-angle plate. The length direction of the two sets of linear guides is consistent with the length direction of the second groove. Two sliding grooves are provided at the bottom of the second slider. The two sliding grooves are respectively slidably engaged with the two linear guides.

[0032] A second linear drive source is mounted on a right-angle plate. The output shaft of the second linear drive source is fixedly connected to the second slider to drive the second slider to move.

[0033] Furthermore, the resilient component includes:

[0034] Two second guide rods are installed longitudinally at the lower end of the second rectangular block. Two second guide holes are provided longitudinally on the second slider. The two second guide rods are slidably disposed in the two second guide holes respectively.

[0035] And two springs respectively installed on the two second guide rods, both springs being located between the second rectangular block and the second slider.

[0036] The two springs ensure that the first rectangular block always elastically contacts the first inclined surface. Thus, when the second linear drive source is activated, it can drive the two second baffles to move obliquely upward, which is beneficial for the second baffles to push the paper.

[0037] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0038] This invention uses a bidirectional adjustment component to drive two first sliders closer together. With the connection of the adjustment component and the pressure plate, each first baffle moves towards the center of the worktable within its corresponding first groove. As multiple first baffles on the left and right sides move inwards towards the worktable, they push the paper and correct any slight deviation, ultimately centering the paper along the length of the worktable and correcting its skewness. Due to the first groove and first baffles, this invention can correct the position of various paper sizes. Simultaneously, a first linear drive source lowers the pressure plate, bringing it close to the paper. The two pressure plates limit the paper's movement, preventing it from being significantly bent during the pushing process, thus ensuring its transport to the feed port. The tensioning mechanism, in conjunction with the two second baffles, prevents the second baffles from obstructing the paper's movement when placed on the worktable. Furthermore, the tensioning mechanism moves the two second baffles diagonally upwards, allowing them to push the paper towards the hot stamping machine. Attached Figure Description

Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0051] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0052] Reference Figures 1 to 8As shown, this embodiment of the invention provides a paper correction device for a hot stamping machine, which is installed on the front side of the feed port 81 of the hot stamping machine 8. It includes: a worktable 1, with multiple horizontally extending first grooves 11 on both the left and right sides of the worktable 1; two second grooves 12 extending towards the rear end of the front end of the worktable 1; multiple first baffles 2 respectively disposed within the multiple first grooves 11; the tops of the multiple first baffles 2 located on the same side of the worktable 1 are connected together by a pressure plate 21; the multiple first baffles 2 at each pressure plate 21 are located at the outer end below the pressure plate 21; and a first slider 3 disposed above each pressure plate 21, with two first sliders 3 at the same height. A height adjustment assembly 4 is provided between a slider 3 and a corresponding pressure plate 21 to adjust the height distance between them. Each height adjustment assembly 4 includes two first linear drive sources 41, which are longitudinally installed at the lower end of the corresponding first slider 3. The output shafts of the two first linear drive sources 41 are fixedly connected to the corresponding pressure plate 21. A bidirectional adjustment assembly 5 is provided on the worktable 1 to drive the two first sliders 3 to move towards each other. Two second baffles 6 are respectively provided in the two second grooves 12. A tensioning mechanism 7 is provided below the worktable 1. The tensioning mechanism 7 can pull the two second baffles 6 to move towards the rear end of the worktable 1 in the corresponding second grooves 12 while moving upward.

[0053] In this embodiment, the hot stamping machine 8 has a paper feed port 81 and two take-up rollers 82 at the feed port 81 for transporting the paper for hot stamping into the hot stamping machine 8. The hot stamping machine 8 is prior art, and its internal structure is not shown in the diagram. The top of the workbench 1 and the gap between the two take-up rollers 82 are at the same height.

[0054] After the paper is processed by the previous process, it can be placed on the worktable 1 by a conveyor belt, a robotic arm, or directly by hand. Since the position of the paper on the worktable 1 cannot be guaranteed to be the same every time, the distance between the first slider 3 and the corresponding pressure plate 21 is adjusted by the distance adjustment component 4 (that is, by running the first linear drive source 41, so that the pressure plate 21 moves downward). As the distance between the pressure plate 21 and the corresponding first slider 3 increases, multiple first baffles 2 are also inserted into the corresponding first grooves 11 to ensure that the pressure plate 21 is as close to the paper as possible, which can prevent the sides of the paper from being pushed laterally. The paper bends at a large angle, and then the two first sliders 3 are driven to move closer to each other by the bidirectional adjustment component 5. Under the connection of the adjustment component 4 and the pressure plate 21, each first baffle 2 moves towards the center of the worktable 1 in the corresponding first groove 11. When the multiple first baffles 2 on the left and right sides move towards the inside of the worktable 1, the paper can be pushed to move and the slight deviation of the paper can be corrected. Finally, the paper is centered in the length direction of the worktable 1, and the slant of the paper is corrected. Due to the setting of the first groove 11 and the first baffle 2, the position of various sizes of paper can be corrected.

[0055] At this point, the two second baffles 6 are still in their initial positions, both at the front end of their respective second grooves 12, and their tops are below the worktable 1. This arrangement prevents the second baffles 6 from obstructing the worktable 1, facilitating the feeding of paper onto the worktable 1 by the conveyor belt or robotic arm. After the paper has been corrected, since there is still a certain distance between the paper and the feed port 81, the tensioning mechanism 7 pulls the two second baffles 6 towards the rear end of the worktable 1 within their respective second grooves 12. Simultaneously, the two second baffles 6 can move upwards within their respective second grooves 12, causing their tops to move above the worktable 1. When the two second baffles 6 then move towards the rear of the worktable 1, they can lift the paper onto the worktable 1. The paper is pushed towards the hot stamping machine 8. When one end of the paper moves to the gap between the two take-up rollers 82 at the feed port 81, the paper can be conveyed by the take-up rollers 82 into the hot stamping machine 8 for further processing. It should be noted that before the second baffle 6 pushes the paper, the pressure plate 21 is still close to the paper. Under the limitation of the two pressure plates 21, the paper can be prevented from being bent significantly during the pushing process, thus affecting the paper's conveyance to the feed port 81. Through the cooperation of the stretching mechanism 7 and the two second baffles 6, the two second baffles 6 can be prevented from blocking the movement of the paper when it is placed on the worktable 1. At the same time, when the stretching mechanism 7 is running, it can also move the two second baffles 6 diagonally upward, so that the second baffles 6 can push the paper towards the hot stamping machine 8.

[0056] Specifically, refer to Figure 1 , Figure 2 and Figure 5 As shown, the bidirectional adjustment assembly 5 includes: two side plates 51 respectively located at the left and right ends of the worktable 1; and two first guide rods 52 located between the two side plates 51. The two first guide rods 52 are arranged laterally, and both ends of each first guide rod 52 are fixedly connected to the two side plates 51 respectively. Each first slider 3 is provided with two first guide holes 31 that are slidably engaged with the two first guide rods 52. The bidirectional adjustment assembly 5 also includes: a bearing seat 53 located inside the left side plate 51; a lead screw 54 mounted on the bearing seat 53, the threads at both ends of the lead screw 54 having opposite directions; a rotating hole 511 opened on the right side plate 51, the right end of the lead screw 54 being rotatably disposed in the rotating hole 511; threaded holes 32 on the two first sliders 3 respectively being threadedly connected to the two ends of the lead screw 54; a motor bracket 55 located outside the right side plate 51; and a rotary driver 56 mounted on the motor bracket 55. The output shaft of the rotary driver 56 is connected to the end of the lead screw 54 via a coupling.

[0057] The two first guide rods 52 enable the two first sliders 3 to be at the same height and slide laterally between the two side plates 51. The first guide rods 52 guide the first sliders 3. When the rotary driver 56 is running, it can drive the lead screw 54 to rotate. Since the threads at both ends of the lead screw 54 are opposite, and the two first sliders 3 are respectively provided with threaded holes 32 that are threaded to the two ends of the lead screw 54, the two first sliders 3 can move closer or further apart when the lead screw 54 rotates, thereby driving the second baffle 6 to move laterally, thus achieving the correction of the paper position.

[0058] Specifically, refer to Figure 4 , Figure 6 and Figure 7 As shown, the stretching mechanism 7 includes: a first rectangular block 71 installed below the worktable 1, the first rectangular block 71 being located between two second baffles 6, the lower end face of the first rectangular block 71 being configured as a first inclined surface 711 extending upward from its front side to its rear side; a second rectangular block 72 connected to the lower ends of the two second baffles 6, the top of the second rectangular block 72 being provided with a second inclined surface 721 that cooperates with the first inclined surface 711; a second slider 73 located directly below the second rectangular block 72, the second slider 73 being elastically connected to the second rectangular block 72 by an elastic component 74; and a linear drive component 75 disposed below the worktable 1, the linear drive component 75 being used to drive the second slider 73 to move laterally.

[0059] In the initial state, the second rectangular block 72 is located at the front end below the first rectangular block 71, and under the action of the elastic component 74, the second rectangular block 72 is always elastically abutting against the first rectangular block 71 (i.e., the first inclined surface 711 and the second inclined surface 721 are in close contact). When the linear drive component 75 drives the second slider 73 to move laterally to the rear side of the worktable 1, it can pull the second slider 73 and the second rectangular block 72 together to move to the rear side of the worktable 1. Under the action of the elastic component 74, the second rectangular block 72 moves obliquely upward along the first inclined surface 711, so that the second baffle 6 moves to the rear side of the worktable 1, and the top of the second baffle 6 also moves to the top of the worktable 1, which is conducive to the second baffle 6 pushing the paper to ensure that the paper can be smoothly pushed into the hot stamping machine 8.

[0060] Specifically, refer to Figure 4 , Figure 6 and Figure 7 As shown, the linear drive assembly 75 includes: a right-angle plate 751 disposed below the worktable 1, with two sets of linear guide rails 752 disposed on the lateral end of the right-angle plate 751, the length direction of the two sets of linear guide rails 752 being consistent with the length direction of the second groove 12; two sliding grooves 731 disposed at the bottom of the second slider 73, the two sliding grooves 731 being slidably engaged with the two linear guide rails 752 respectively; and a second linear drive source 753 mounted on the right-angle plate 751, the output shaft of the second linear drive source 753 being fixedly connected to the second slider 73 for driving the second slider 73 to move.

[0061] The elastic component 74 includes: two second guide rods 741 longitudinally mounted on the lower end of the second rectangular block 72; two second guide holes 732 longitudinally provided on the second slider 73; and two second guide rods 741 slidably disposed in the two second guide holes 732 respectively; and two springs 742 respectively mounted on the two second guide rods 741; and the two springs 742 are located between the second rectangular block 72 and the second slider 73.

[0062] The linear guide rail 752 ensures that the second slider 73 always moves along the front and rear sides of the worktable 1. Under the support of the right-angle plate 751, the second slider 73 is also guaranteed to be stable in the longitudinal direction. The two second guide rods 741 enable the second rectangular block 72 to move longitudinally above the second slider 73. Under the action of the two springs 742, the second rectangular block 72 is guaranteed to abut against the first inclined surface 711. When the second linear drive source 753 drives the second slider 73 to move to the rear side of the worktable 1, it can also drive the second baffle 6 to move to the rear side of the worktable 1. At the same time, the second baffle 6 rises above the worktable 1, ensuring that the second baffle 6 can effectively push the paper.

[0063] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
