Description

Technical Field

[0001] This utility model belongs to the field of screen printing transmission technology, and more specifically, it relates to a dual servo motor feeding and pulling roller for a printer. Background Technology

[0002] In the printing industry, screen printing is a widely used printing technology for the decoration, labeling, and electronic circuit printing of various products. Compared with other printing technologies, screen printing has the advantages of clear printing effect, high pattern complexity, and wide applicability.

[0003] Most existing printing equipment on the market adopts a feeding tension control combined with a pulling servo motor control mode in terms of feeding and pulling mechanisms, which meets the basic printing production needs. However, in the actual printing process, it is difficult to maintain the tension stability throughout the feeding and pulling process by relying solely on a single feeding tension control and pulling servo motor. The printing material vibrates during the conveying process, resulting in slight differences in the pulling length, which in turn affects the accuracy, smoothness, and aesthetics of the final printed product. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a printer with dual servo motor feeding and pulling rollers. This solves the problem that in the prior art, traditional printing equipment relies solely on a single feeding tension control and pulling servo motor, making it difficult to maintain tension stability throughout the feeding process. This results in vibration of the printing material during transport, causing slight differences in the pulling length, which in turn affects the accuracy, smoothness, and aesthetics of the final printed product.

[0005] The purpose and effect of this utility model of a printer with dual servo motor feeding and pulling rollers are achieved by the following specific technical means:

[0006] A printer with dual servo motor feeding and pulling rollers includes an equipment box and a printing table. The printing table is located on the top of the equipment box, and a screen printing plate is located on the top of the printing table. A printing component is located above the printing table. A feeding component is located at one end of the printing table corresponding to the screen printing plate. The feeding component includes a feeding servo motor and a feeding suction roller, and the main shaft of the feeding servo motor is connected to the feeding suction roller. A receiving component is located at the other end of the printing table, corresponding to the screen printing plate. The receiving component includes a receiving servo motor and a receiving suction roller. The receiving servo motor and the receiving suction roller are located at the other end of the printing table.

[0007] In a preferred embodiment, the feeding assembly further includes two sets of first mounting plates, with two sets of first mounting plates respectively arranged on both sides of the printing table, and a rotatable feeding suction roller arranged between the two sets of first mounting plates. A feeding servo motor is arranged on one side of one set of first mounting plates corresponding to the feeding suction roller.

[0008] In a preferred embodiment, two sets of first mounting rods are provided between the two sets of first mounting plates, and two sets of auxiliary wheels are fitted on each of the two sets of first mounting rods. A feeding rack is connected to the side of the two sets of first mounting plates away from the printing table.

[0009] In a preferred embodiment, the receiving assembly includes two sets of second mounting plates. One end of the printing table is connected to the two sets of second mounting plates. One set of second mounting plates has a through hole on one side. The receiving servo motor is provided at one end of the through hole. The main shaft of the receiving servo motor passes through the through hole and is connected to the receiving suction roller.

[0010] In a preferred embodiment, four sets of rotatable collecting wheels are provided on the outer side of the collecting suction roller, and two sets of second mounting rods are provided between the two sets of second mounting plates. The four sets of collecting wheels are respectively sleeved on the two sets of second mounting rods.

[0011] In a preferred embodiment, a frame is provided on one side of the printing table, a mounting side plate is provided on the top of the frame, a horizontal moving component is provided on one side of the mounting side plate corresponding to the screen printing plate, a lifting component is connected to the electric slider of the horizontal moving component, and the printing component is provided at the bottom of the lifting component that can be raised and lowered.

[0012] In a preferred embodiment, the horizontal moving component is provided with two sets of horizontally movable transfer components corresponding to the feeding component and the receiving component.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting up the feeding and receiving components, dual servo motor control is adopted using a feeding servo motor and a receiving servo motor. The feeding servo motor drives the feeding suction roller, and the receiving servo motor works in conjunction with the receiving suction roller. The two work together to control the speed and tension of feeding and receiving, which solves the problem of unstable tension during the feeding process of traditional printing equipment. This ensures that the printing material moves forward at a uniform speed and smoothly, eliminating the slight stretching or shrinkage caused by uneven tension. This improves the stability of the printing material conveying, so that the patterns and text on the printed products can be accurately aligned, the lines are straight and clear, and the edges are sharp, thus improving the precision of the printed products.

[0015] 2. With the setting of auxiliary wheels and take-up wheels, the auxiliary wheels on the two sets of first mounting rods gently receive and guide the printing material, disperse its force, and avoid the material from hard friction with the feeding mechanism to cause jamming; the four sets of take-up wheels at the take-up end rotate flexibly to match the running rhythm of the take-up suction roller, smoothly roll up the printing material, reduce tension fluctuations, make the conveying process smoother, and make the material surface flat and smooth.

[0016] 3. The horizontal moving component and the lifting component can be used to position and adjust the printing components. This not only helps to maintain an appropriate distance between the print head and the screen printing plate, ensuring the consistency of the printing effect, but also allows the position of the two sets of transfer components to be adjusted according to the printing materials of different sizes, thus improving the adaptability of the equipment.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a printer with dual servo motor feeding and pulling rollers, including an equipment box 11 and a printing table 12. The equipment box 11 is located at the bottom and connected to an external circuit, while the printing table 12 is mounted on top of it. A screen printing plate 13 is provided on the surface of the printing table 12 to support the printing process. Above the printing table 12, a printing assembly 14 for performing the printing operation is also provided. At one end of the printing table 12, corresponding to the position of the screen printing plate 13, a feeding assembly is installed. This feeding assembly includes a feeding servo motor 21 and a feeding suction roller 22. The main shaft of the feeding servo motor 21 is connected to the feeding suction roller 22 to drive the feeding suction roller 22 and feed the material to be printed onto the screen printing plate 13. At the other end of the printing table 12, also corresponding to the position of the screen printing plate 13, a receiving assembly is provided to receive... The material assembly includes a receiving servo motor 31 and a receiving suction roller 32. The receiving servo motor 31 is installed on one side of the printing table 12, and its main shaft is connected to the receiving suction roller 32, which is responsible for collecting the printed material. The feeding servo motor 21 and the receiving servo motor 31 are used for dual servo motor control. Specifically, the feeding servo motor 21 is responsible for driving the feeding suction roller 22 to transport the material to be printed to the screen printing plate 13; while the receiving servo motor 31 works in conjunction with the receiving suction roller 32 to collect the printed material. The coordinated operation of the two servo motors allows the speed and tension of the entire material conveying process to be regulated, avoiding the tension instability problem that is prone to occur in the feeding stage of traditional printing equipment. This ensures that the printing material can maintain a uniform and stable forward movement, enhancing the stability of material conveying.

[0027] Please see as follows Figure 2 As shown, the feeding assembly also includes two sets of first mounting plates 23, which are fixed on both sides of the printing table 12. A rotatable feeding suction roller 22 is installed between the two sets of first mounting plates 23. A feeding servo motor 21 is provided on one side of one set of first mounting plates 23 corresponding to the feeding suction roller 22, so that the feeding servo motor 21 can directly drive the feeding suction roller 22 to rotate, thereby driving the printing material to be fed.

[0028] Two sets of first mounting rods 24 are also provided between the two sets of first mounting plates 23. Each of these first mounting rods 24 is fitted with two sets of rotatable auxiliary wheels 25. At the same time, a feeding rack 26 is connected to the side of the two sets of first mounting plates 23 away from the printing table 12. The four sets of auxiliary wheels 25 can bear and guide the conveying of printing materials, disperse the external force on the material during movement, and avoid excessive friction between the material and the feeding components, thereby preventing jamming. The feeding rack 26 provides support and guidance for the conveyed material.

[0029] Please see as follows Figure 3As shown, the receiving assembly includes two sets of second mounting plates 33, which are mounted on one end of the printing table 12. One set of second mounting plates 33 has a through hole on one side, and a receiving servo motor 31 is installed at one end of the through hole. The main shaft of the receiving servo motor 31 passes through the through hole and is connected to the receiving suction roller 32, so that the receiving servo motor 31 can directly drive the receiving suction roller 32 to rotate. After printing is completed, the receiving suction roller 32 can roll up the printing material to collect the completed printed material.

[0030] Please see as follows Figure 4 As shown, four sets of rotatable take-up rollers 34 are installed on the outside of the take-up suction roller 32. At the same time, two sets of second mounting rods 35 are provided between the two sets of second mounting plates 33. The four sets of take-up rollers 34 are respectively sleeved on the two sets of second mounting rods 35. The four sets of take-up rollers 34 can rotate flexibly with the operation of the take-up suction roller 32, and cooperate with its rhythm to complete the smooth winding of the printing material, reduce the tension fluctuations that may occur during the take-up process, and make the entire conveying process smoother and more fluid.

[0031] Please see as follows Figure 1 As shown, a frame 15 is installed on one side of the printing table 12, and a mounting side plate 16 is installed on the top of the frame 15. A horizontal moving component 17 is installed on one side of the mounting side plate 16 corresponding to the position of the screen printing plate 13. A lifting component 18 is connected to the electric slider of the horizontal moving component 17. The bottom of the pneumatic cylinder of the lifting component 18 is connected to the printing component 14. When the equipment is started, the horizontal moving component 17 drives the lifting component 18 and the printing component 14 below to move horizontally along the guide rail to reach the designated printing area. Then, the lifting component 18 starts to operate, adjusting the height of the printing component 14 so that the printing head of the printing component 14 maintains an appropriate distance from the screen printing plate 13. This prevents excessive printing pressure due to the distance being too close, resulting in ink accumulation and blurring of the printed patterns and text. It also avoids problems such as uneven ink adhesion and poor printing effect due to the distance being too far, ensuring the consistency of the printing effect. The horizontal moving component 17 is equipped with two sets of horizontally movable transfer components 19 corresponding to the feeding component and the receiving component.
