Description
Technical Field
[0001] The utility model relates to the technical field of rotary screen printing machines, in particular to a transverse alignment device of a rotary screen printing machine. Background Art
[0002] As a screen printing machine, the rotary screen printing machine works in the following way: the fabric is transported along the guide belt under the rotary screen, and the rotary screen continuously rolls on the fabric. During the rolling process of the rotary screen, the slurry in the rotary screen is printed on the fabric through the mesh on the rotary screen to achieve printing. During the printing process, the installation position of the rotary screen is directly related to the printing quality. To ensure the printing quality, a pattern alignment device needs to be set so that the position of the rotary screen can be adjusted. The pattern alignment of the rotary screen printing machine includes horizontal pattern alignment and oblique pattern alignment. Among them, horizontal pattern alignment refers to the pattern alignment with horizontal deviation. The specific pattern alignment operation is to adjust the horizontal position of the rotary screen, move the rotary screen horizontally, and correct the horizontal deviation of the pattern.
[0003] The existing horizontal alignment devices of rotary screen printing machines, such as those disclosed in the patent documents with Chinese patent application numbers 201420315204.X and 201120214996.8, mostly adopt drive structures such as screw nuts or worm gears, and the drive structures are all connected to the horizontal sliding body of the rotary screen in a transmission manner. Although such horizontal alignment devices can realize the horizontal movement of the horizontal sliding body of the rotary screen under the drive of the drive structures such as screw nuts or worm gears, after the drive structure is connected to the horizontal sliding body of the rotary screen, the horizontal sliding body of the rotary screen cannot move freely due to the restraint of the drive structure. When loading and unloading the rotary screen, the horizontal sliding body of the rotary screen cannot be pushed manually and flexibly and randomly, and can only be driven to move by the drive structure, which is extremely unfavorable for the operation of loading and unloading the rotary screen, and greatly reduces the operation efficiency. Utility Model Content
[0004] The utility model aims at providing a transverse alignment device for a rotary screen printing machine.
[0005] The technical solution to achieve the purpose of the utility model is: a transverse alignment device for a rotary screen printing machine, comprising a transverse track, on which a first transverse slider and a second transverse slider are movably installed, the first transverse slider and the second transverse slider are connected to the two ends of the rotary screen in a one-to-one correspondence, and a nut block is also slidably installed on the transverse track, the nut block is located between the first transverse slider and the second transverse slider, the nut block is threadedly mounted on a screw rod, the screw rod is arranged parallel to the transverse track, the screw rod is connected to a motor and driven to rotate by the motor, a cylinder is installed on the frame, and the telescopic rod of the cylinder is connected to the second transverse slider.
[0006] Furthermore, the first transverse slider and the second transverse slider are slidably or rollingly installed on the transverse track.
[0007] Furthermore, the nut block is close to the first transverse slider, so that the nut block can be used to limit the first transverse slider.
[0008] Further, the screw is installed at the output end of the motor. The screw can be rotatably installed on the frame, or directly installed at the output end of the motor. Due to the limitation of the installation space, preferably, the screw is installed at the output end of the motor.
[0009] Furthermore, the motor is mounted on the frame.
[0010] Furthermore, the cylinder is located between the first transverse slider and the second transverse slider. The cylinder can be located outside the second transverse slider or inside the second transverse slider. Compared with the outside, the inside of the second transverse slider has more installation space and is more convenient to install.
[0011] Furthermore, the cylinder is hinged to the frame, and the telescopic rod of the cylinder is hinged to the second transverse slider. Under the hinged installation, the cylinder can be parallel to the transverse track or not, and the installation of the cylinder is more flexible.
[0012] Furthermore, the telescopic rod of the cylinder is parallel to the transverse track.
[0013] Furthermore, the transverse track is a split structure. The transverse track can be an integrated structure or a split structure. When the transverse track is a split structure, it is more convenient to install the first transverse slider, the second transverse slider and the nut block.
[0014] Furthermore, the transverse rail is arranged on the frame.
[0015] The horizontal alignment device of the rotary screen printing machine of the utility model, through the combined use of the motor and the cylinder, can be driven one by one with the movement of the rotary screen in two directions, for example, the motor is responsible for the movement of the rotary screen in the positive direction, and the cylinder is responsible for the movement of the rotary screen in the reverse direction; if the motor is responsible for the movement of the rotary screen in the reverse direction, the cylinder is responsible for the movement of the rotary screen in the positive direction. Under the combined use of the motor and the cylinder, a single motor or cylinder only needs to drive the rotary screen to move in one direction, without taking into account the movement of the rotary screen in two directions at the same time. It is for this reason that when the nut block on the screw drives the first horizontal slider to drive the rotary screen to move horizontally, the nut block can be independently set relative to the first horizontal slider without forming a connection with the first horizontal slider. The nut block and the first horizontal slider are separated and do not form a mutual restraint, so they can move flexibly. The flexibly movable first transverse slider is extremely beneficial to the loading and unloading of the round screen. In particular, during the loading and unloading process of the round screen, the first transverse slider can be flexibly moved manually without relying on the drive of the nut block, thereby facilitating the loading and unloading of the round screen and improving the loading and unloading efficiency of the round screen.
[0016] The horizontal alignment device of the rotary screen printing machine of the utility model adopts the motor and the cylinder to provide power for it. The motor and the cylinder can be automated power sources to provide conditions for intelligent adjustment, thereby greatly improving the adjustment efficiency. In the horizontal alignment device of the rotary screen printing machine of the utility model, the first horizontal slider and the second horizontal slider can move to any position along the horizontal track, that is, stepless adjustment can be performed, and the rotary screen can achieve stepless alignment with high alignment accuracy.
[0017] In addition, in the transverse alignment device of the rotary screen printing machine of the utility model, the nut block can not only support the first transverse slider, so that the first transverse slider and the rotary screen installed between the first transverse slider and the second transverse slider are moved from the second transverse slider to the first transverse slider side for alignment; but also limit the rotary screen installed between the first transverse slider and the second transverse slider during the process of the first transverse slider moving to the second transverse slider side for alignment, so that the cylinder-driven alignment is more accurate.

[0021] The following is a detailed description of the preferred embodiment of the horizontal alignment device of the rotary screen printing machine of the utility model in conjunction with the accompanying drawings:
[0022] like Figures 1 to 3 As shown, a transverse alignment device of a rotary screen printing machine includes a transverse track 10, on which a first transverse slider 11 and a second transverse slider 12 are movably installed, and the first transverse slider 11 and the second transverse slider 12 are connected to the two ends of the rotary screen 100 in a one-to-one correspondence. A nut block 2 is also slidably installed on the transverse track 10, and the nut block 2 is located between the first transverse slider 11 and the second transverse slider 12. The nut block 2 is threadedly mounted on a screw rod 3, and the screw rod 3 is arranged parallel to the transverse track 10. The screw 3 is transmission-connected to a motor 4 and driven to rotate by the motor 4. A cylinder 5 is installed on a frame 20, and a telescopic rod 51 of the cylinder 5 is connected to the second transverse slider 12.
[0023] In the horizontal alignment device of the rotary screen printing machine of the utility model, the first horizontal slider 11 and the second horizontal slider 12 are both slidably mounted on the horizontal track 10, the rotary screen 100 is located between the first horizontal slider 11 and the second horizontal slider 12, one end of the rotary screen 100 is mounted on the first horizontal slider 11, and the other end is mounted on the second horizontal slider 12. The nut block 2 located between the first horizontal slider 11 and the second horizontal slider 12 is slidably mounted on the horizontal track 10, and is used to push the first horizontal slider 11 and limit the first horizontal slider 11; after the nut block 2 is threadedly mounted on the screw rod 3, the screw rod 3 is rotated to drive the nut block 2 to move along the horizontal track 10; the motor 4 provides power for the rotation of the screw rod 3. The cylinder 5 provides power for pushing the second horizontal slider 12.
[0024] In the horizontal alignment device of the rotary screen printing machine of the utility model, when the second horizontal slider 12 moves toward the first horizontal slider 11 for alignment, the motor 4 drives the screw rod 3 to rotate, and the rotating screw rod 3 drives the nut block 2 to move along the horizontal track 10 under the action of the thread, and the nut block 2 moving toward the first horizontal slider 11 along the horizontal track 10 presses against the first horizontal slider 11, so that the first horizontal slider 11 and the rotary screen 100 installed between the first horizontal slider 11 and the second horizontal slider 12 move from the second horizontal slider 12 to the first horizontal slider 11. After adjustment, the motor 4 drives to drive the nut block 2 to retreat.
[0025] The horizontal alignment device of the rotary screen printing machine of the utility model, when the first horizontal slider 11 moves toward the second horizontal slider 12 for alignment, the cylinder 5 is started, and the cylinder 5 is actuated to drive the second horizontal slider 12 and the rotary screen 100 installed between the first horizontal slider 11 and the second horizontal slider 12 to move from the first horizontal slider 11 to the second horizontal slider 12. During the movement, the nut block 2 limits the first horizontal slider 11, so that the rotary screen 100 can be moved into place.
[0026] The horizontal alignment device of the rotary screen printing machine of the utility model, through the combined use of the motor 4 and the cylinder 5, can be driven by the motor 4 and the cylinder 5 in one-to-one correspondence with the movement of the rotary screen 100 in two directions, such as the motor 4 is responsible for the movement of the rotary screen 100 in the positive direction, and the cylinder 5 is responsible for the movement of the rotary screen 100 in the reverse direction; if the motor 4 is responsible for the movement of the rotary screen 100 in the reverse direction, the cylinder 5 is responsible for the movement of the rotary screen 100 in the positive direction. Under the combined use of the motor 4 and the cylinder 5, a single motor 4 or the cylinder 5 only needs to drive the rotary screen 100 to move in one direction, without taking into account the movement of the rotary screen 100 in two directions at the same time. It is for this reason that when the nut block 2 on the screw 3 drives the first horizontal slider 11 to drive the rotary screen 100 to move horizontally, the nut block 2 can be independently set relative to the first horizontal slider 11, and is not connected to the first horizontal slider 11. The nut block 2 and the first horizontal slider 11 are separated, do not form mutual restraint, and can move flexibly. The flexibly movable first transverse slider 11 is extremely beneficial to the loading and unloading of the round screen 100. In particular, during the loading and unloading process of the round screen 100, the first transverse slider 11 can be flexibly moved manually without relying on the drive of the nut block 2, thereby facilitating the loading and unloading of the round screen 100 and improving the loading and unloading efficiency of the round screen 100.
[0027] The horizontal alignment device of the rotary screen printing machine of the utility model adopts the motor 4 and the cylinder 5 to provide power for it. The motor 4 and the cylinder 5 can be automated power sources to provide conditions for intelligent adjustment, thereby greatly improving the adjustment efficiency. In the horizontal alignment device of the rotary screen printing machine of the utility model, the first horizontal slider 11 and the second horizontal slider 12 can move to any position along the horizontal track 10, that is, stepless adjustment can be performed, and the rotary screen 100 can achieve stepless alignment with high alignment accuracy.
[0028] In addition, in the transverse alignment device of the rotary screen printing machine of the utility model, the nut block 2 can not only support the first transverse slider 11, so that the first transverse slider 11 and the rotary screen 100 installed between the first transverse slider 11 and the second transverse slider 12 are moved from the second transverse slider 12 to the first transverse slider 11 side for alignment; but also limit the first transverse slider 11 and the rotary screen 100 installed between the first transverse slider 11 and the second transverse slider 12 during the process of the first transverse slider 11 moving toward the second transverse slider 12 side for alignment, so that the cylinder 5 can drive the alignment with higher accuracy.

[0030] In the lateral alignment device of the rotary screen printing machine of the present invention, preferably, the nut block 2 is close to the first lateral slider 11, so that the nut block 2 is used to limit the first lateral slider 11.
[0031] In the horizontal alignment device of the rotary screen printing machine of the utility model, the screw rod 3 can be rotatably mounted on the frame 20, or directly mounted on the output end of the motor 4. Due to the limitation of the installation space, preferably, the screw rod 3 is mounted on the output end of the motor 4.

The cylinder 5 can be located outside the second horizontal slider 12 or inside the second horizontal slider 12. Compared with the outside, the inside of the second horizontal slider 12 has more installation space and is more convenient to install.
[0034] In the horizontal alignment device of the rotary screen printing machine of the utility model, preferably, the cylinder 5 is hinged to the frame 20, and the telescopic rod 51 of the cylinder 5 is hinged to the second horizontal slider 12. Under the hinged installation, the cylinder 5 can be parallel to the horizontal track 10 or not, and the installation of the cylinder 5 is more flexible.
[0035] In the transverse alignment device of the rotary screen printing machine of the present invention, preferably, the telescopic rod 51 of the cylinder 5 is parallel to the transverse track 10 .
[0036] In the lateral alignment device of the rotary screen printing machine of the utility model, preferably, the lateral track 10 is a split structure.
