[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] This utility model provides a technical solution: such as Figures 1-5As shown, in this embodiment, a printing machine for knitted fabric processing includes a mounting frame 1 and a printing machine body 2. The printing machine body 2 is fixedly connected to the top of one end of the mounting frame 1. A conveying mechanism is installed inside one end of the mounting frame 1, a tensioning mechanism is installed on the top of the mounting frame 1, and a correction mechanism is installed on the inner side of the mounting frame 1. The conveying mechanism includes a first pressure roller 3 and a second pressure roller 13. A transmission wheel 14 is fixedly connected to the outer side of the same end of the first pressure roller 3 and the second pressure roller 13. A transmission belt 15 is sleeved on the outer side between the transmission wheels 14. A first motor 5 is fixedly connected to the outer side of the mounting frame 1. One end of the first pressure roller 3 is fixedly connected to the first motor 5. The first pressure roller 3 is fixedly connected to the output end of the first motor 5, and an auxiliary roller 4 is provided at the bottom of the first pressure roller 3. The auxiliary roller 4 is rotatably connected to the inner side of the mounting frame 1. The auxiliary roller 4 is used to cooperate with the first pressure roller 3 to transport the knitted fabric. During transport, one end of the knitted fabric passes between the first pressure roller 3 and the auxiliary roller 4, passes above the tensioning mechanism, and then passes below the second pressure roller 13. As the first motor 5 rotates, it will drive the first pressure roller 3 to transport the knitted fabric. During the rotation of the first pressure roller 3, the second pressure roller 13 will also rotate synchronously through the cooperation between the transmission wheel 14 and the transmission belt 15 to transport the knitted fabric.
[0025] The tensioning mechanism includes a first housing 6 and a second housing 7. A second motor 16 is fixedly connected to the top of the first housing 6. A screw 17 is fixedly connected to the output end of the second motor 16. The screw 17 is rotatably connected to the inside of the first housing 6. A first guide rod 18 is fixedly connected to the inside of the second housing 7.
[0026] The screw 17 is threadedly connected to a first connecting block 19, and the first guide rod 18 is movably connected to a second connecting block 20. The first connecting block 19 and the second connecting block 20 are rotatably connected to a tension roller 8 via a bearing. The bottom surface of the knitted fabric is on the top surface of the tension roller 8. When the knitted fabric becomes slack during the conveying process, the second motor 16 can be started. The second motor 16 drives the screw 17 to rotate, and then the first connecting block 19 moves upward along the screw 17. Then, the tension roller 8 moves steadily upward with the cooperation of the second connecting block 20 and the first guide rod 18, lifting the knitted fabric upward and ensuring that the knitted fabric maintains appropriate tension to ensure the stable conveying of the knitted fabric.
[0027] The correction mechanism includes a connecting plate 9 and two limiting plates 10. The top of the connecting plate 9 near the printing machine body 2 has two symmetrically arranged sliding grooves 11. A second guide rod 21 is fixedly connected inside each of the two sliding grooves 11. A slider 22 is fixedly connected to the bottom of each of the two limiting plates 10. The slider 22 is slidably connected to the outside of the second guide rod 21. Through the cooperation of the sliding grooves 11, the slider 22 and the second guide rod 21, the stable movement of the limiting plate 10 can be ensured.
[0028] Two electric cylinders 23 are fixedly connected to the outside of the mounting frame 1. The output ends of the two electric cylinders 23 are fixedly connected to one side of the adjacent limiting plate 10. The electric cylinders 23 are activated according to the width of the knitted fabric. The electric cylinders 23 will push the limiting plate 10 to move towards the middle of the connecting plate 9 to ensure that the knitted fabric is between the bottom of the limiting plate 10. The limiting plate 10 will limit the knitted fabric. Under the operation of the conveying mechanism, the knitted fabric is stably conveyed by the limiting plate 10 without deviation.
[0029] A connecting frame 12 is fixedly connected to the inner side of the mounting frame 1. A brush plate 24 is fixedly connected to the bottom surface of the connecting frame 12, and two dust collection buckets 25 are fixedly connected to the inner side of the bottom of the connecting frame 12.
[0030] Two suction pipes 26 are fixedly connected to the top of the connecting frame 12. One end of the two suction pipes 26 is connected to the adjacent suction hopper 25, and the other end of the suction pipes 26 is connected to the external high-pressure blower. During the conveying process, the knitted fabric will pass under the brush plate 24 and come into contact with the brush plate 24. The brush plate 24 will intercept the broken threads on the surface of the knitted fabric. As the external high-pressure blower operates, the broken threads will be sucked into the suction hopper 25, conveyed to the external high-pressure blower by the suction pipes 26, and then discharged from the output end of the external high-pressure blower.
[0031] This utility model provides a printing machine for knitted fabric processing. The specific working principle is as follows: A first motor 5 rotates, driving a first pressure roller 3 to rotate. The knitted fabric passes between the first pressure roller 3 and an auxiliary roller 4. During the rotation of the first pressure roller 3, transmission is achieved through the cooperation of a transmission wheel 14 and a transmission belt 15. The second pressure roller 13 also rotates synchronously, conveying the knitted fabric. Before one end of the knitted fabric passes the second pressure roller 13, it first passes above a tension roller 8. If slack occurs during the conveying of the knitted fabric, the second motor 16 can be started. The second motor 16 drives a screw 17 to rotate, thereby causing the first connecting block 19 to move upward along the screw 17. The tension roller 8 moves steadily upward in cooperation with the second connecting block 20 and the first guide rod 18, lifting the knitted fabric upward to ensure that the knitted fabric maintains appropriate tension and to ensure the stable conveying of the knitted fabric. As the second pressure roller 13 conveys the fabric, it passes under the brush plate 24 and comes into contact with the brush plate 24. The brush plate 24 intercepts the broken threads on the surface of the knitted fabric. As the external high-pressure blower operates, the broken threads are sucked into the dust collection hopper 25 and conveyed to the external high-pressure blower through the dust collection pipe 26. The fabric is then discharged from the output end of the external high-pressure blower. Subsequently, the knitted fabric is guided by the limiting plate 10 and enters the printing machine body 2 for printing.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
