Description

Technical Field

[0001] The utility model relates to the technical field of rotary screen printing machines, in particular to a rotary screen seat of a rotary screen printing machine. Background Art

[0002] As a screen printing machine, the working mechanism of the rotary screen printing machine is that 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. In the existing rotary screen printing machine, the rotary screen is usually installed on the mesh head seat with two ends. Under the structure of the vertical mesh head seat, the vertical installation space is relatively abundant, and the mesh head transmission structure is mostly arranged below the mesh seat, as disclosed in the patent document of Chinese patent application No. 200520061063.4. In this type of rotary screen printing machine, when working, the slurry in the upper rotary screen flows downward and flows to the mesh head transmission structure below, which not only easily causes corrosion damage to the mesh head transmission structure, but more seriously, it is also easy to cause electrical failures and increase equipment maintenance costs. In addition, the traditional vertical mesh head seats are mostly lifted and lowered by cylinders. Specifically, the mesh head seats at both ends correspond to a set of cylinder lifting mechanisms. Under this lifting structure, the mesh head seats at both ends are independent of each other, and it is difficult to synchronize the movements of the cylinder lifting mechanisms at both ends. At the same time, improper height adjustment at both ends of the round mesh will increase the probability of mesh twisting and breaking. Utility Model Content

[0003] The utility model aims at a rotary screen seat of a rotary screen printing machine.

[0004] The technical solution to achieve the purpose of the utility model is: a rotary screen seat of a rotary screen printing machine, comprising a rotating shaft installed on the machine seat, a first swing arm and a second swing arm are installed on the rotating shaft, the first swing arm and the second swing arm are arranged at intervals along the axial direction of the rotating shaft, a first chuck is installed on the first swing arm, and a second chuck is installed on the second swing arm. The first chuck and the second chuck are coaxial and are used together to install the rotary screen, the first chuck is provided with a screen head transmission wheel coaxial with the first chuck, and a rotary screen driving mechanism is installed on the first swing arm. The rotary screen driving mechanism is located on one side of the screen head transmission wheel and is connected to the screen head transmission wheel in transmission connection.

[0005] Furthermore, the round screen driving mechanism is connected to the mesh head transmission wheel through a belt. The round screen driving mechanism can be connected to the mesh head transmission wheel through a belt, or through a gear. Compared with gears, belt transmission connection can achieve long-distance transmission, that is, the round screen driving mechanism and the mesh head transmission wheel can be spaced far apart. When the round screen driving mechanism and the mesh head transmission wheel are spaced far apart, it is difficult for the slurry in the round screen to be brought to the round screen driving mechanism, thereby effectively ensuring the safety of the use of the round screen driving mechanism.

[0006] Furthermore, the rotary screen driving mechanism includes a motor and a reducer, and the motor, the reducer and the screen head transmission wheel are sequentially connected. When working, the motor drives the reducer and the screen head transmission wheel in sequence to rotate the first chuck and the rotary screen fixed thereon.

[0007] Furthermore, the first swing arm and the second swing arm are respectively located at two ends of the rotating shaft.

[0008] Furthermore, the rotating shaft includes a first small shaft and a second small shaft, the first small shaft and the second small shaft are coaxial, the first swing arm is installed on the first small shaft, and the second swing arm is installed on the second small shaft. The rotating shaft can be integrated, consisting of one shaft; or it can be split, including the first small shaft and the second small shaft. Since the horizontal span of the rotary screen printing machine of the utility model is large, for the convenience of installation, preferably, the rotating shaft includes the first small shaft and the second small shaft.

[0009] The rotary screen seat of the rotary screen printing machine of the utility model, through the setting of the rotating shaft and the first swing arm and the second swing arm thereon, enables the first chuck and the second chuck to be respectively installed on the first swing arm and the second swing arm, and the rotary screen fixedly installed on the first chuck and the second chuck can be side-mounted under the action of the first swing arm and the second swing arm. Under the rotary screen side-mounting structure, on the one hand, the horizontal installation space of the first swing arm is relatively abundant, and when installing the rotary screen driving mechanism, the rotary screen driving mechanism can be conveniently installed on one side of the screen head transmission wheel, so that the slurry in the rotary screen will not flow to the rotary screen driving mechanism during operation, and the rotary screen driving mechanism is prevented from being corroded or causing electrical failure due to the slurry flowing thereon; on the other hand, the rotary screen is installed on the same rotating shaft through the first swing arm and the second swing arm, and when the rotary screen is raised and lowered, the rotating shaft can be rotated to make the rotary screen as a whole rotate and raise and lower together, and the lifting and lowering actions of the two ends of the rotary screen are consistent, and there is no situation where the two ends of the rotary screen are raised and lowered at inappropriate heights, which effectively avoids the twisting of the screen and the breaking of the screen.

[0015] The rotary screen seat of the rotary screen printing machine of the utility model, the rotating shaft 1 is installed on the machine base 10 and can rotate under the action of driving force. The first swing arm 2 and the second swing arm 3 are movably installed on the rotating shaft 1, and are used as mounting brackets for the first chuck 21 and the second chuck 31. The first chuck 21 and the second chuck 31 movably installed on the rotating shaft 1 are rotatable and are used together to install the rotary screen 101. The mesh head transmission wheel 4 is integrated with the first chuck 21.

The rotating shaft 1 can be integrated, consisting of one shaft; it can also be split, including the first small shaft 11 and the second small shaft 12. Since the horizontal span of the rotary screen printing machine of the utility model is large, for the convenience of installation, preferably, the rotating shaft 1 includes the first small shaft 11 and the second small shaft 12.
