Description

Technical Field

[0001] This utility model relates to the field of printing and embossing technology, specifically to an accurate positioning fixture for printing and embossing. Background Technology

[0002] In the modern printing industry, embossing is a core technology for enhancing product quality and added value, and is widely used in packaging, labeling, decorative materials and other fields. As consumers' requirements for the quality of printed materials continue to increase, the precise alignment of embossed patterns with printed text and images has become the focus of industry attention.

[0003] The core function of precision positioning fixtures for printing embossing is to ensure that the relative position of the embossing mold and the printing material (such as paper, leather, plastic film) is fixed, so as to avoid pattern misalignment caused by material offset and tension changes.

[0004] Traditional precision positioning fixtures for printing and embossing have poor adaptability to irregularly shaped materials or materials with large thickness fluctuations due to mechanical positioning structures (such as baffles and slots), and are prone to positioning reference deviation due to mechanical wear. Alternatively, although vision positioning systems have high accuracy, they are affected by factors such as material surface reflection and stains, resulting in unstable recognition success rate. In addition, the equipment cost and maintenance difficulty are high, which reduces the practicality of precision positioning fixtures for printing and embossing.

[0005] To address this issue, we propose a precise positioning fixture for printing and embossing. Utility Model Content

[0006] This invention provides an accurate positioning fixture for printing and embossing, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] An embodiment of this utility model provides an accurate positioning fixture for printing and embossing, comprising:

[0009] Base;

[0010] The first conveyor belt, located inside the base, is used to transport the paper.

[0011] A heat dissipation grille A is fixedly installed at the front end of the base. A second servo motor is fixedly installed inside the front end of the base behind the heat dissipation grille A. A embossing wheel is fixedly connected to the output end of the second servo motor. A clamping wheel is provided below the embossing wheel. A fixed frame is rotatably connected to both ends of the clamping wheel. A first guide rod is slidably connected to both ends of the fixed frame. A hydraulic press is fixedly connected to the bottom end of the fixed frame.

[0012] A heat dissipation grille B is fixedly installed on one front end of the base, and a first servo motor is fixedly installed inside the front end of the base on one side of the heat dissipation grille B.

[0013] The positioning device, located on the inner top of the base, is used to position the paper.

[0014] The above technical solution allows for embossing of paper by using a second servo motor in conjunction with an embossing wheel, while the positioning device further enhances the embossing effect.

[0015] Furthermore, the positioning device includes a lead screw fixedly connected to the output end of the first servo motor. The outer arc surfaces of both ends of the lead screw are provided with threads in opposite directions. The two ends of the lead screw are respectively symmetrically threaded to a first slider. A fixed box is fixedly connected to one side of the first slider. A second slider is fixedly connected to the other end of the fixed box. A second guide rod is slidably connected to the bottom end of the second slider. The two ends of the second guide rod are fixedly connected to the inner ends of the base.

[0016] The above technical solution, with its opposite-direction threads, enables the first servo motor to start, synchronously driving the two fixed boxes to move towards each other, ensuring centered positioning.

[0017] Furthermore, a second conveyor belt is provided inside the fixed box. Rotating shafts are symmetrically snapped onto the inner sides of both ends of the second conveyor belt. The two ends of the two rotating shafts are rotatably connected to the two sides of the inner wall of the fixed box. Four fixing plates are fixedly connected to one side of the inner wall of the fixed box. A sliding rod is connected through the middle of the four fixing plates. Fixing members are symmetrically fixed to both ends of the sliding rod. A roller is rotatably connected to the other end of the fixing member. A spring is provided on the outer arc surface of the sliding rod.

[0018] Through the above technical solution, the tension of the slide bar can push the second conveyor belt downward, thereby making the second conveyor belt tightly hold the paper.

[0019] Furthermore, a baffle is provided at the rear of the fixing box, and the bottom end of the baffle is flush with the top surface of the first conveyor belt.

[0020] The above technical solution, namely the setting of the baffle, can prevent the paper from shifting left and right, thus avoiding tilting of the embossing.

[0021] Furthermore, the inner ends of the first conveyor belt are symmetrically connected to a driven shaft and a driving shaft, respectively. One end of the driving shaft is connected to a belt on its outer arc surface, and the other end of the belt is connected to the outer arc surface of one end of the embossing wheel.

[0022] The above technical solution allows the embossing wheel to rotate synchronously with the first conveyor belt, further improving the uniformity and integrity of the embossing.

[0023] Furthermore, rollers that are rotatably connected to the top inner side of the base are provided on the outer sides of both ends of the first conveyor belt.

[0024] The above technical solution, namely the setting of rollers, can further improve the tension of the paper and at the same time prevent the paper from being scratched by the equipment.

[0025] The beneficial effects of this utility model are:

[0026] 1. By using a positioning device, the first servo motor, lead screw, first slider, second conveyor belt, slide bar, fixing parts, and rollers work together. The first servo motor drives the first slider to move, and the distance between the fixing parts on both sides is adjusted synchronously. This effectively avoids the left and right offset of the paper due to insufficient width adaptation, ensuring that the embossing pattern is accurately aligned with the edge of the paper. At the same time, the spring setting allows the fixing parts to make the second conveyor belt fit tightly against the paper through the rollers for fixation, and rotate with the paper to avoid the paper tilting and offset, further improving the practicality of the accurate positioning fixture for printing embossing.

[0027] 2: By using the first conveyor belt, driven shaft, drive shaft, belt, second servo motor, embossing wheel and clamping wheel in combination, the second servo motor drives the embossing wheel to rotate, realizing the embossing of paper. At the same time, under the action of the belt, the second servo motor can synchronously drive the first conveyor belt to move and feed the paper, realizing synchronous rotation, improving the uniformity and integrity of the overall embossing of the paper, and further improving the use effect of the accurate positioning tooling for printing embossing.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] like Figures 1 to 6 As shown, an embodiment of this utility model provides a precise positioning fixture for printing embossing, comprising: a base 1; a first conveyor belt 2 is provided inside the base 1 for conveying paper; a heat dissipation grid A3, the heat dissipation grid A3 is fixedly installed at the front end of the base 1, a second servo motor 6 is fixedly installed inside the front end of the base 1 behind the heat dissipation grid A3, the output end of the second servo motor 6 is fixedly connected to an embossing wheel 7, a clamping wheel 71 is provided below the embossing wheel 7, a fixed frame 72 is rotatably connected to both ends of the clamping wheel 71, and a first servo motor 72 is slidably connected to both ends of the fixed frame 72. A guide rod 73 is provided, and a hydraulic press 74 is fixedly connected to the bottom end of the fixing frame 72. A heat dissipation grid B4 is fixedly installed on the front side of one end of the base 1. A first servo motor 5 is fixedly installed inside the front end of the base 1 on one side of the heat dissipation grid B4. A positioning device 10 is provided on the inner side of the top of the base 1 for positioning the paper. The fixing frame 72 is connected to the hydraulic press 74 by a fixed connection. When the hydraulic press 74 is started, the fixing frame 72 can move up and down under the action of the hydraulic press 74, thereby adjusting the gap between the embossing wheel 7 and the clamping wheel 71.

[0037] like Figures 5 to 6As shown, the positioning device 10 includes a lead screw 101 fixedly connected to the output end of the first servo motor 5. The outer arc surfaces of both ends of the lead screw 101 are provided with threads in opposite directions. The two ends of the lead screw 101 are symmetrically threaded to a first slider 102. A fixed box 103 is fixedly connected to one side of the first slider 102, and a second slider 104 is fixedly connected to the other end of the fixed box 103. A second guide rod 105 is slidably connected to the bottom end of the second slider 104. The two ends of the second guide rod 105 are fixedly connected to the inner ends of the base 1. A second conveyor belt 112 is provided inside the fixed box 103. Rotating shafts 111 are symmetrically snapped onto the inner sides of the two ends of the second conveyor belt 112. The two ends of the two rotating shafts 111 are rotatably connected to the fixed box 10. On both sides of the inner wall of the fixed box 103, four fixed plates 106 are fixedly connected to one side of the inner wall. A slide rod 107 is connected through the middle of the four fixed plates 106. Fixing members 109 are fixedly connected to both ends of the slide rod 107. A roller 110 is rotatably connected to the other end of the fixing member 109. A spring 108 is provided on the outer arc surface of the slide rod 107. A baffle is provided at the rear of the fixed box 103. The bottom end of the baffle is flush with the top surface of the first conveyor belt 2. The lead screw 101 is connected to the first slider 102 by a threaded connection. When the first servo motor 5 is started, the lead screw 101 rotates under the action of the first servo motor 5, thereby driving the two lead screws 101 to move towards each other and adjust according to the width of the paper.

[0038] like Figures 3 to 6 As shown, the driven shaft 21 and the driving shaft 22 are symmetrically connected to the inner ends of the first conveyor belt 2. The outer arc surface of one end of the driving shaft 22 is connected to the belt 23, and the other end of the belt 23 is connected to the outer arc surface of one end of the embossing wheel 7. Rollers 8 are rotatably connected to the top of the inner side of the base 1 at both ends of the first conveyor belt 2. The belt 23 is connected to the driving shaft 22 and the embossing wheel 7 by means of snap-fit ​​connection. When the second servo motor 6 starts and drives the embossing wheel 7 to rotate, the belt 23 drives the driving shaft 22 to rotate under the action of the embossing wheel 7. At this time, the first conveyor belt 2 transports the paper.

[0039] In this embodiment of the utility model (working principle), during use, the external paper roller is moved to one end of the feed port of the device. Then, according to the width of the paper, the first servo motor 5 is started to drive the two fixing boxes 103 to move left and right to adjust according to the width of the paper. After adjustment, the two sides of the paper are attached to the back baffle of the fixing box 103 and smoothly inserted into the bottom of the fixing box. Under the elastic action of the spring 108, the second conveyor belt 112 forms an adaptive clamping structure with the fixing member 109 and the roller 110, which can automatically adapt to the paper thickness for fixing, ensuring that papers of different weights can be stably fixed and avoiding indentation damage. Then, according to the thickness of the paper, the user starts the hydraulic press 74 to drive the fixing frame 72 to slide up and down, thereby driving the clamping wheel 71 to move, and then adjusting the clamping wheel 71 and the embossing wheel 7. The spacing is adjusted to meet the requirements of various embossing processes such as relief and raised textures. Then, the second servo motor 6 is started to drive the embossing wheel 7 to rotate. At the same time, under the action of the belt 23, the drive shaft 22 is also driven to rotate, which in turn drives the first conveyor belt 2 to move the paper. Meanwhile, the second conveyor belt 112 rotates synchronously with the paper under the action of friction, forming a double conveying guarantee at the front and rear ends. Then, the moving paper is passed between the embossing wheel 7 and the clamping wheel 71. With the cooperation of the embossing wheel 7 and the clamping wheel 71, the paper is embossed, which effectively reduces problems such as paper wrinkles and deviations caused by unstable clamping, and greatly improves the embossing production efficiency and yield.
