Description

Technical Field

[0001] The utility model relates to the technical field of stretching and leveling for printing machines, and more specifically to a stretching and leveling device for printing machines. Background Art

[0002] Currently, there are two types of screen printing for printing, one is flat screen printing, and the other is rotary screen printing. After the fabric or lace embroidery is processed and formed, it must be stretched to become the fabric for production.

[0003] The existing stretching and leveling devices for printing machines on the market have a relatively simple structure. During the stretching process, the fabric is damaged due to excessive pulling force, or the fabric shrinks due to insufficient pulling force, resulting in waste of resources and greatly affecting work efficiency. Therefore, in view of this, the existing structure and deficiencies are studied and improved to provide a stretching and leveling device for printing machines, with the expectation of achieving a more practical value. Summary of the Utility Model

[0004] In order to overcome the above defects of the prior art, the utility model provides a stretching and leveling device for printing machines to solve the problems existing in the above background art.

[0005] The utility model provides the following technical solution: A stretching and leveling device for printing machines, including a box body, a hot air blower, and a winding device. A winding device is arranged at one end of the box body. The outer surface of the top of the box body is fixedly installed with a hot air blower, and the output end of the hot air blower extends into the interior of the box body. One side of the box body is provided with a feeding port, and one end of the feeding port is fixedly installed with a moving chamber. One end of the moving chamber is provided with a motor body. The output end of the motor body is fixedly installed with a bidirectional threaded rod, and the other end of the bidirectional threaded rod is connected to the interior of the moving chamber through a bearing. Both sides of the bidirectional threaded rod are provided with movable mounting boxes. The top of the movable mounting box is fixedly installed with an L-shaped vertical plate. The mutually close ends of the L-shaped vertical plates are provided with a mounting frame, and a transport roller is arranged inside the mounting frame. The interior of the box body is fixedly installed with a smoothing support box, and the outer surface of the smoothing support box is provided with heat dissipation holes. The top inner wall of the box body is fixedly installed with a first hydraulic cylinder, and the bottom of the first hydraulic cylinder is fixedly installed with a smoothing plate. In actual use, through the setting of the above structure, both ends of the fabric are limited between two transport rollers, and then the fabric is stretched and flattened by driving the bidirectional threaded rod by the motor. Then, through the combined use of the smoothing plate and the hot air blower, the pattern on the fabric is quickly dried, so that the fabric is quickly shaped, preventing the fabric from shrinking after stretching and saving time.

[0006] Further, one end of the L-shaped vertical plate close to each other is provided with a mounting groove. The bottom of the inner wall of the mounting groove is installed with a screw rod body through a bearing. A rectangular block is arranged on the outer side of the screw rod body. A handle is fixedly installed at the top of the screw rod body. In actual use, through the setting of the above structure, this mechanism may be used to adjust the height between the transport rollers to adapt to fabrics of different thicknesses, ensuring that the fabric can maintain appropriate tension and position during the stenter leveling process.

[0007] Further, a guide rod is fixedly installed inside the moving chamber. A through groove is opened on the movable installation box, and the guide rod is slidably installed inside the through groove.

[0008] Further, a discharge port is arranged on one side of the box body close to the winding device. A bottom plate is arranged on the discharge port of the box body. A return spring is fixedly installed on the top of the bottom plate. A movable plate is fixedly installed on the top of the return spring. A second hydraulic cylinder is fixedly installed on the top of the box body. A connecting plate is fixedly installed at the bottom of the second hydraulic cylinder. In actual use, through the setting of the above structure, through the combined use of the return spring and the movable plate, a certain buffering and supporting effect can be provided when the fabric is moved out of the discharge port, preventing the fabric from being impacted or damaged too much.

[0009] Further, the outer surface of the movable plate is arc-shaped.

[0010] Further, a transparent observation window is arranged on the outer surface of the box body.

[0012] 1. By providing a moving chamber, a motor body, a bidirectional threaded rod, a movable installation box, an L-shaped vertical plate, a mounting frame, a transport roller, a first hydraulic cylinder, a flattening plate and a flattening support box, with this design, the two ends of the fabric are respectively limited between the two transport rollers, and then the fabric is stretched and flattened by driving the bidirectional threaded rod with the motor. Then, through the combined use of the flattening plate and the hot air blower, the pattern on the fabric is quickly dried, so that the fabric is quickly shaped, preventing the fabric after stenter from shrinking back, saving time.

[0013] 2. By providing a mounting groove, a screw rod body and a rectangular block, with this design, this mechanism may be used to adjust the height between the transport rollers to adapt to fabrics of different thicknesses, ensuring that the fabric can maintain appropriate tension and position during the stenter leveling process.
