Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a blown film integrated printing machine. Background Technology

[0002] Nowadays, various texts or patterns are printed onto the surface of plastic films using printing machines. Due to the different materials of the plastic films, their elasticity varies, resulting in different tensions. Therefore, when printing on plastic films of different materials, it is impossible to adjust the tension of the plastic film according to the requirements, which leads to curling or wrinkling on the surface of the plastic film, thus affecting the printing effect. At the same time, after the plastic film is printed, it needs to be collected by a winding machine. However, the printing speed of existing printing machines cannot be adjusted according to the winding speed of the winding machine, thus affecting the winding machine's ability to rewind the printed plastic film. Utility Model Content

[0003] To address the aforementioned problems, this application provides a blown film integrated printing machine. Through the setting of a tensioning mechanism, the tension of the plastic film can be adjusted to prevent curling or wrinkling during printing, thereby improving the printing quality. By setting a control mechanism, the power of the drive mechanism can be adjusted according to the tension of the plastic film by the tensioning mechanism, which in turn adjusts the rotation speed of the printing machine, and consequently, the printing speed of the plastic film. This allows the printing speed of the plastic film to be synchronized with the winding speed of an external winding machine, improving the printing efficiency of the plastic film.

[0004] To address the problems of existing technologies, this utility model provides a blown film integrated printing machine, including a frame, a printing machine mounted on the frame, multiple movable rollers for guiding plastic film mounted on the printing machine, a tensioning mechanism mounted on the printing machine, a drive mechanism linked to one side of the printing machine, and a control mechanism mounted on the printing machine, the control mechanism being linked to the tensioning mechanism and the drive mechanism.

The electronic ruler is mounted on the mounting plate and connected to the tensioning mechanism. The control panel is mounted on the printing press, and the potentiometer is mounted on the control panel and connected in parallel with the electronic ruler.

[0006] Preferably, the drive mechanism includes a motor and a gearbox, the motor is located on the outside of the printing press, and a gearbox is connected to one side of the motor.

[0007] Preferably, the tensioning mechanism includes limit blocks, sliding members, a rotating shaft, a tensioning wheel, a pushing member, and a connecting rod. Two limit blocks are respectively disposed on the upper sides of the printing press, with openings on opposite sides of each block. Each limit block has a mounting groove. The number of sliding members is the same as the number of limit blocks and corresponds one-to-one. The sliding members are disposed within the mounting grooves of their respective limit blocks. The rotating shaft is disposed between the two limit blocks, with both ends extending into the openings of the limit blocks at both ends. Both ends of the rotating shaft are connected to the sliding surfaces of the corresponding sliding members. The tensioning wheel is rotatably disposed on the rotating shaft. The number of pushing members is the same as the number of sliding members and corresponds one-to-one. The pushing members are disposed on the printing press, with one of the two pushing members located on the same side of the printing press as the electronic ruler.

Detailed Implementation

[0013] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0014] See Figures 1 to 6 As shown, a blown film integrated printing machine includes a frame 1, a printing machine 2 mounted on the frame 1, multiple movable rollers 3 for guiding plastic film mounted on the printing machine 2, a tensioning mechanism 4 mounted on the printing machine 2, a drive mechanism 5 linked to one side of the printing machine 2, and a control mechanism 6 mounted on the printing machine 2. The control mechanism 6 is linked to the tensioning mechanism 4 and the drive mechanism 5.

[0015] When printing on plastic film, one end of the plastic film is first placed on the printing machine 2, and then the drive mechanism 5 is started, causing the printing machine 2 to begin printing on the plastic film. The multiple movable rollers 3 on the printing machine 2 facilitate the movement of the plastic film on the printing machine 2. After the plastic film is printed, it comes out from the output end of the printing machine 2 and is then wound up by an external winding machine. When it is necessary to adjust the tension of the plastic film, the tensioning mechanism 4 is started to adjust the tension of the plastic film on the printing machine 2, thereby improving the printing efficiency of the plastic film and preventing the plastic film from curling or wrinkling. When the tension of the plastic film changes, the power of the drive mechanism 5 is controlled by the control mechanism 6, which in turn controls the printing speed of the printing machine 2, so that the printing speed of the plastic film can be synchronized with the winding speed of the external winding machine, thereby improving the printing efficiency of the plastic film.

[0016] See Figure 2 ,Figure 4 and Figure 5 As shown, the control mechanism 6 includes a mounting plate 61, a control panel 64, an electronic ruler 62, and a potentiometer 63. The mounting plate 61 is mounted on the printing machine 2 and is located on one side of the tensioning mechanism 4. The electronic ruler 62 is mounted on the mounting plate 61 and is connected to the tensioning mechanism 4. The control panel 64 is mounted on the printing machine 2, and the potentiometer 63 is mounted on the control panel 64. The potentiometer 63 and the electronic ruler 62 are connected in parallel.

[0017] When the tensioning mechanism 4 adjusts the tension of the plastic film, the tension dimension of the plastic film can be detected by the electronic ruler 62 and potentiometer 63. The tension data of the plastic film is then transmitted to the drive mechanism 5, which controls the rotation speed of the drive mechanism 5. At the same time, since the electronic ruler 62 and potentiometer 63 are connected in parallel, they can independently control the rotation speed of the drive mechanism 5 in the printing machine 2. This allows the printing speed of the plastic film to be synchronized with the winding speed of the external winding film, thereby adjusting the printing speed of the plastic film and improving the practicality of the device.

[0018] See Figure 1 and Figure 3 As shown, the drive mechanism 5 includes a motor 51 and a gearbox 52. The motor 51 is located on the outside of the printing press 2, and a gearbox 52 is connected to one side of the motor 51. It also includes a frequency converter for controlling the motor 51. The frequency converter is connected to an electronic ruler 62 and a potentiometer 63.

[0019] The motor 51 provides power to the printing press 2, facilitating its printing of plastic film. Since the frequency converter is connected to the electronic ruler 62 and potentiometer 63, the frequency of the frequency converter can be adjusted via the potentiometer 63 based on the film output speed of the external blown film machine. This adjustment is made when the electronic ruler 62 is in position and the tension is sufficient. The frequency converter then controls the rotation speed of the motor 51, ensuring that the printing speed of the printing press 2 matches that of the external blown film machine. This improves the printing quality and efficiency of the plastic film, achieving a seamless integration between the printing press 2 and the external blown film machine.

[0020] See Figure 4 , Figure 5 and Figure 6As shown, the tensioning mechanism 4 includes a limiting block 41, a sliding member 42, a rotating shaft 43, a tensioning wheel 44, a pushing member 45, and a connecting rod 46. The limiting block 41 has two members respectively disposed on the upper sides of the printing press 2. Each limiting block 41 has an opening 412 on its opposite side. The limiting block 41 has a mounting groove 411. The number of sliding members 42 is the same as the number of limiting blocks 41 and corresponds one-to-one. The sliding members 42 are disposed within the mounting grooves 411 of the corresponding limiting blocks 41. The rotating shaft 43 is disposed between the two limiting blocks 41, with both ends extending to the two ends of the shaft. The tensioning wheel 44 is rotatably mounted on the rotating shaft 43 within the opening 412 of the limiting block 41, and the two ends of the rotating shaft 43 are connected to the sliding surfaces of the corresponding sliding members 42. The number of the pushing members 45 is the same as the number of the sliding members 42 and they correspond one-to-one. The pushing members 45 are mounted on the printing machine 2. One of the two pushing members 45 is located on the same side of the printing machine 2 as the electronic ruler 62. The pushing members 45 and the sliding members 42 are linked together. One end of the connecting rod 46 is connected to the end of the rotating shaft 43 near the electronic ruler 62, and the other end of the connecting rod 46 is connected to the electronic ruler 62.

[0021] The mounting groove 411 provided by the limiting block 41 facilitates the installation of the sliding member 42 into the mounting groove 411. The sliding member 42 allows the rotating shaft 43 to move along the opening 412 provided by the limiting block 41, thereby driving the tensioning wheel 44 to move together. Through the cooperation of the pushing member 45 and the sliding member 42, the tensioning wheel 44 on the rotating shaft 43 moves to a designated position at the opening 412 provided by the limiting block 41, thereby adjusting the tension of the plastic film. At the same time, the connecting rod 46 connects the measuring end of the electronic ruler 62 to the rotating shaft 43, allowing the measuring end of the electronic ruler 62 to move in the same direction as the rotating shaft 43. The tension data of the plastic film can be measured by the moving distance of the measuring end of the electronic ruler 62, which allows the electronic ruler 62 to adjust the rotation speed of the drive mechanism 5 according to the tension of the plastic film.

[0022] See Figure 4 and Figure 6 As shown, the sliding member 42 includes a slide table 421 and a slider 422. The slide table 421 is disposed in the mounting groove 411 opened in the limiting block 41. The sliding surface of the slide table 421 is disposed at one end of the rotating shaft 43. The slider 422 is slidably disposed on the slide table 421. The slider 422 is fixedly connected to one end of the rotating shaft 43. One side of the slider 422 is connected to the pushing end of the pusher 45.

[0023] By cooperating with the slide table 421 and the slider 422, the rotating shaft 43 can slide on the slide table 421 via the slider 422. Since one side of the slider 422 is connected to the pushing end of the pusher 45, the slider 422 can move automatically on the slide table 421 when the pusher 45 is activated, thereby controlling the movement of the tension wheel 44 without manual adjustment, improving the automation of the device and reducing the workload of the operator.

[0024] See Figure 4 and Figure 6 As shown, the pushing member 45 includes a pushing cylinder 451 and a push rod 452. The pushing cylinder 451 is disposed on one side of the electronic ruler 62. The output end of the pushing cylinder 451 is disposed in the direction of the limiting block 41. The output end of the pushing cylinder 451 is provided with a push rod 452. The end of the push rod 452 away from the pushing cylinder 451 is connected to the sliding member 42.

[0025] By pushing the cylinder 451 and push rod 452, power is provided for the movement of the rotating shaft 43 on the sliding member 42. At the same time, the movement distance of the tensioning wheel 44 on the rotating shaft 43 can be made more precise, so as not to cause the tension of the plastic film to deviate from the required requirements.

[0026] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
