Description

Technical Field

[0001] This utility model relates to the technical field of printing equipment, and in particular to an embossing device for printing equipment. Background Technology

[0002] In the printing industry, embossing is a common post-processing technique used to create three-dimensional patterns or text on the surface of paper or other printed materials. However, existing embossing devices in printing equipment have many shortcomings in practical applications.

[0003] Traditional embossing devices often struggle to precisely adjust the embossing position when embossing printed materials. This not only results in low positional accuracy of the embossed pattern, affecting the aesthetics and quality of the printed product, but also lacks flexibility and adaptability when dealing with printing tasks of different sizes or design requirements. Furthermore, most existing devices cannot effectively handle fluctuations in paper thickness. When the paper thickness is uneven, inconsistent embossing pressure can easily occur, leading to over- or under-embossing in some areas, severely impacting the stability and consistency of the embossing effect. Moreover, traditional embossing devices also have limitations in pressure control, making it difficult to precisely adjust the pressure according to actual needs, thus failing to meet the printing industry's high-precision requirements for embossing effects.

[0004] Existing embossing devices for printing equipment have significant shortcomings in terms of position adjustment accuracy, paper thickness adaptability, and pressure control accuracy, making it difficult to efficiently and stably complete high-quality embossing tasks. There is an urgent need for a new type of embossing device that can overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide an embossing device for printing equipment, which aims to solve the problem of inaccurate embossing position adjustment in the prior art.

[0006] To achieve the above objectives, the present invention provides an embossing device for printing equipment, comprising an equipment support base and a bracket mounted on the equipment support base. The equipment support base has a lower mold placement plate. The bracket has a cylinder fixing block sliding rod and a drive screw arranged parallel to each other. The cylinder fixing block sliding rod slides through one end of the cylinder fixing block, and the drive screw is threaded to the other end of the cylinder fixing block. A cylinder is located at the bottom of the cylinder fixing block, and a cylinder push rod and an upper mold connecting block are located at the bottom of the cylinder. The drive screw can be rotated to allow the cylinder fixing block to move along the width direction of the equipment support base under the guidance of the cylinder fixing block sliding rod, thereby adjusting the relative position of the upper mold connecting block and the equipment support base.

[0007] Preferably, the equipment support base is provided with a lower mold placement plate limiting slide rod and a transmission screw arranged in parallel. The lower mold placement plate limiting slide rod slides through one end of the lower mold placement plate, and the transmission screw is threaded to the other end of the lower mold placement plate. The transmission screw can be rotated to allow the lower mold placement plate to move along the width direction of the equipment support base under the guidance of the lower mold placement plate limiting slide rod.

[0008] Preferably, the drive screw and the transmission screw are connected by a synchronous belt, which enables the lower mold placement plate and the upper mold connecting block to move horizontally and synchronously.

[0009] Preferably, the end of the drive screw is equipped with a hand crank.

[0010] Preferably, the equipment support base is provided with a pressing roller and a support roller at both ends of the lower mold placement plate. The pressing roller is located above the support roller and is connected by a pressing roller drive gear and a support roller drive gear. The two pressing rollers are connected by a drive belt, and one of the pressing rollers is connected to a power motor.

[0011] Preferably, the bracket is provided between the cylinder push rod and the upper mold connecting block. The bracket is provided with a fixed slide cylinder. The fixed slide cylinder is provided with a limiting slide groove to slide with the top of the upper mold connecting block. A compression spring is provided vertically in the limiting slide groove to abut against the top of the upper mold connecting block.

[0012] Preferably, the top of the upper mold connecting block has an outwardly extending annular protrusion, and the bottom opening of the limiting slide groove contracts towards the center to form an annular structure to restrict the annular protrusion from detaching, wherein the central portion of the annular structure allows the middle portion of the upper mold connecting block to pass through.

[0013] Preferably, the upper mold connecting block is provided with a limiting protrusion on the outside of the annular protrusion, and the side wall of the limiting slide groove is provided with a groove to slide and cooperate with the limiting protrusion.

[0014] Preferably, the top of the bracket is provided with a controller, and a pressure sensor electrically connected to the controller is provided between the top wall of the limiting slide groove and the top of the compression spring. The controller can adjust the descent amplitude of the cylinder through a solenoid valve according to the pressure signal captured by the pressure sensor to adapt to the pressing pressure.

[0015] Preferably, the surface of the device support base is provided with a pressure display screen and a pressure adjustment button that are electrically connected to the controller. The target pressure value can be set through the pressure adjustment button, and the controller precisely controls the downward thrust of the cylinder through a solenoid valve and displays the actual pressure value on the pressure display screen.

[0016] In summary, this utility model has the following beneficial technical effects: This invention achieves precise adjustment of the embossing position by setting an adjustable lower mold placement plate and a matching upper mold connecting block. When the hand crank is manually turned, the drive screw rotates and, through threaded transmission, moves the cylinder fixing block along the width direction of the equipment support. Simultaneously, the rotation of the drive screw drives the transmission screw to rotate via a transmission belt, causing the lower mold placement plate and the cylinder to achieve horizontal synchronous displacement. This effectively ensures precise alignment of the embossing templates, thereby improving the accuracy and quality of the embossing process and meeting the high precision requirements of the printing industry for embossing effects.

[0017] This invention offers significant advantages in pressure control. When the cylinder pushes the cylinder rod downwards, the upper mold connecting block slides within the fixed slide to compress the spring. The pressure signal captured by the pressure sensor is transmitted to the controller in real time. Based on this signal, the controller adjusts the cylinder's descent amplitude via a solenoid valve, automatically adapting the pressing pressure to ensure that the embossing quality is unaffected by fluctuations in paper thickness. Furthermore, the pressure display screen and pressure adjustment button allow operators to intuitively monitor and adjust the pressure. The controller precisely controls the downward thrust of the cylinder via the solenoid valve and displays the actual pressure value on the pressure display screen, achieving closed-loop precise control of the embossing pressure and further improving the stability and reliability of the embossing process.

[0018] This invention features closely coordinated components that automate and precisely control operations from paper feeding, position adjustment, and pressure regulation to mold protection. The pressure roller and support roller on the equipment support base are connected by gears and a transmission belt, providing power for the paper's uniform forward movement and ensuring stable paper flow. Simultaneously, the lower mold placement plate limiting slide rod and the cylinder fixing block sliding rod guide the movement of the lower mold placement plate and the cylinder fixing block, respectively, ensuring stability during movement. The entire device improves the efficiency and quality of embossing processes while also being easy to operate, monitor, and adjust, demonstrating promising application prospects and market value.

[0021] 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.

[0022] This utility model discloses an embossing device for printing equipment, including an equipment support base 1, with a bracket 29 mounted on top of the equipment support base 1. The equipment support base 1 serves as the basic support structure for the entire device. A pressure roller 24 and a support roller 25 are respectively mounted on its left and right ends, with the pressure roller 24 positioned above the support roller 25. The two rollers are connected by a pressure roller drive gear 26 and a support roller drive gear 27. The brackets 29 for the left and right pressure rollers 24 are connected by a drive belt 28. A power motor 23 is mounted on the shaft of the pressure roller 24 located at the left end of the equipment support base 1, providing power for the uniform forward movement of the paper. During operation, the paper to be embossed is placed between the pressure roller 24 and the support roller 25. The power motor 23, in conjunction with the pressure roller drive gear 26, the support roller drive gear 27, and the drive belt 28, causes the paper to move forward stably.

[0023] The support rollers 25 at both ends of the equipment support base 1 are close to each other, and a lower mold placement plate limiting slide rod 22 and a transmission screw 15 are respectively set on one side. The lower mold placement plate limiting slide rod 22 and the transmission screw 15 are at the same height. The lower mold placement plate limiting slide rod 22 passes through the left end of the horizontally arranged lower mold placement plate 16, and the transmission screw 15 is threaded through the right end of the lower mold placement plate 16. When the equipment is running, the paper passes over the lower mold placement plate 16. The drive screw 2 is directly above the transmission screw 15. The two are connected by a synchronous belt 13 to realize transmission. The drive screw 2 is located below the top of the bracket 29. The end of the drive screw 2 is equipped with a hand crank 18 for easy manual operation to adjust the concave position. At the same time, a cylinder fixing block sliding rod 17 is provided directly above the lower mold placement plate limiting slide rod 22. The cylinder fixing block sliding rod 17 and the active lead screw 2 are at the same height. The cylinder fixing block sliding rod 17 passes through the left end of the horizontally arranged cylinder fixing block 3, and the active lead screw 2 and the right end of the cylinder fixing block 3 are threadedly connected. The cylinder 4 is fixed to the bottom of the cylinder fixing block 3 and is set downward.

[0024] Manually turning the hand crank 18 drives the drive screw 2 to rotate. Through threaded transmission, the cylinder fixing block 3 moves along the width of the equipment support base 1, adjusting the concave position. The rotation of the drive screw 2 is transmitted via the drive pulley 12 and the synchronous belt 13 to the transmission pulley 14, causing the transmission screw 15 to rotate. This ensures that the lower mold placement plate 16 and the cylinder 4 achieve horizontal synchronous displacement, guaranteeing precise alignment of the concave and convex mold plates. During this process, the cylinder fixing block sliding rod 17 guides the movement of the cylinder fixing block 3, while the lower mold placement plate limiting sliding rod 22 ensures the stability of the lower mold placement plate 16 during movement.

[0025] A cylinder push rod 5 extends vertically downward from the bottom of cylinder 4. A fixed slide cylinder 6 is fixedly connected to the bottom of cylinder push rod 5. The fixed slide cylinder 6 has a limiting groove 9 inside to slide with the top of upper mold connecting block 10. The top of upper mold connecting block 10 has an annular protrusion extending outward. The bottom opening of the limiting groove 9 narrows inward to form an annular structure. The annular structure restricts the annular protrusion and prevents it from detaching. The central part of the annular structure allows the middle part of upper mold connecting block 10 to pass through. In addition, upper mold connecting block 10 has a limiting protrusion 11 outside the annular protrusion. The side wall of the limiting groove 9 has a corresponding groove that slides and engages with the limiting protrusion 11 to ensure that upper mold connecting block 10 does not rotate around its own axis and avoids misalignment and damage with lower mold.

[0026] When cylinder 4 operates, it pushes cylinder push rod 5 downwards, thereby causing fixed slide cylinder 6 and upper mold connecting block 10 to press down together. A controller 19 is installed at the top of bracket 29. A compression spring 8 is vertically positioned above the top of upper mold connecting block 10 within the limiting slide groove 9. The top of the compression spring 8 abuts against a pressure sensor 7 located on the top wall of the limiting slide groove 9. In cases of uneven paper thickness, when the upper mold below upper mold connecting block 10 contacts and compresses the paper and lower mold, if the paper is too thick, upper mold connecting block 10 will compress the compression spring 8. Upper mold connecting block 10 itself slides upwards relative to the fixed slide cylinder 6. At this time, the compression spring 8 is further compressed to increase the force on pressure sensor 7. The pressure signal captured by pressure sensor 7 is transmitted to controller 19 in real time. Based on this signal, controller 19 adjusts the descent amplitude of cylinder 4 via a solenoid valve, automatically adapting the pressing pressure to ensure that the embossing quality is not affected by fluctuations in paper thickness.

[0027] The surface of the equipment support base 1 is equipped with a pressure display screen 20 and a pressure adjustment button 21 electrically connected to the controller 19. Operators can use these to set the target pressure value. The controller 19 precisely controls the downward thrust of the cylinder 4 via a solenoid valve, and displays the actual pressure value directly on the pressure display screen 20, facilitating monitoring and adjustment by on-site operators. When the cylinder 4 pushes the cylinder push rod 5 downwards, acting on the upper mold connecting block 10, the upper mold connecting block 10 slides within the fixed slide cylinder 6, compressing the compression spring 8. The reaction force of the compression spring 8 is fed back to the controller 19 via the pressure sensor 7. The controller 19 compares the actual pressure with the preset pressure and dynamically adjusts the downward pressing depth of the cylinder 4 pushing the cylinder push rod 5 via the solenoid valve, achieving closed-loop precise control of the convex pressure.

[0028] The components of this invention work closely together, from paper feeding, position adjustment, pressure control to mold protection, to achieve automated and precise operation, effectively improving the efficiency and quality of embossing processes for printed materials and meeting the high precision requirements of the printing industry for embossing effects.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
