Description

Circular screen printer

Technical Field

The utility model belongs to the technical field of textile printing and dyeing's technique and specifically relates to a circular screen printer is related to.

Background

The rotary screen printing is a printing mode for printing color paste in a rotary screen onto a fabric under the driving of pressure by using a scraper. The circular screen printing machine is generally composed of four parts, namely a cloth feeding device, a printing machine head, a drying device and a cloth dropping device, has the characteristics of simplicity and convenience in operation, low labor intensity and high yield, and is suitable for printing of various fabrics.

The Chinese patent with the publication number of CN208469287U discloses a circular screen printer, which comprises a main frame, a cloth feeding device and a printing device are sequentially arranged on the main frame, the circular screen printer further comprises a hair removing device which removes wool on cloth entering the printing device, the hair removing device is arranged on the main frame and is positioned between the cloth feeding device and the printing device, and the hair removing device is abutted to the surface of the cloth entering the printing device. The device utilizes the unhairing device to clear the lint on the surface of the cloth entering the printing device, avoids incomplete printed patterns caused by the lint in the printing process, and further improves the printing quality of the cloth.

The above prior art solutions have the following drawbacks: the brush articulates on first rotation roller among the above-mentioned device, and then is inconvenient to carry out the change work to the brush, and along with going on of stamp process, the condition of ageing and wearing and tearing can appear in the brush, and can influence the cleaning work of brush to cloth surface batting after wearing and tearing appear in the brush for part batting still adheres on the cloth surface, and then influences the quality that the stamp process was carried out to the cloth.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, one of the purposes of the utility model is to provide a circular screen printer has the convenient characteristics of dismantling and installing of brush for can carry out the change of brush according to the degree of wear of brush, the brush after avoiding wearing and tearing influences the work is got rid of to the batting on cloth surface.

The above object of the present invention is achieved by the following technical solutions:

the utility model provides a circular screen printer, includes into cloth holder, it is connected with many brush rollers to rotate on the cloth holder to advance, can dismantle on the brush roller and be connected with the brush, the both ends tip of brush inner wall is provided with the installation piece, the brush roller along the axial seted up with installation piece complex mounting groove, follow on the mounting groove the arc wall has been seted up to brush roller circumference, seted up on the one end lateral wall of arc wall with installation piece complex spacing groove, be provided with in the spacing groove and be used for the locking installation piece axial position's locking piece.

Through adopting above-mentioned technical scheme, when needs are dismantled the brush roller, at first remove the locking piece and the locking of installation piece, then slide the installation piece along the brush roller axial, leave the spacing groove and get into the arc wall until the installation piece, then rotate the brush along brush roller circumference until the installation piece gets into the mounting groove in, slide the brush roller along the mounting groove at last and dismantle and change work, when wearing and tearing or ageing appear in the brush, make things convenient for the staff to carry out timely change to the brush, the work is got rid of to the batting of avoiding influencing the cloth surface.

The present invention may be further configured in a preferred embodiment as: the locking piece includes adapter sleeve, spring and spacing pearl, set up threaded hole on the lateral wall of spacing groove, the adapter sleeve outside is provided with the external screw thread, adapter sleeve one end is sealed, the other end is provided with the throat, the diameter of throat is less than the diameter of spacing pearl, spacing pearl is installed in the adapter sleeve, the both ends of spring butt adapter sleeve bottom surface and spacing pearl respectively, seted up on the lateral wall of installation piece with spacing pearl complex spacing hole.

Through adopting above-mentioned technical scheme, when the installation work of brush is carried out to needs, slide installation piece on the brush inner wall along mounting groove and arc wall in proper order to finally slide and get into the spacing inslot, the spacing groove plays the restriction to brush circumference rotation, and then drives the brush and takes place to rotate when making the brush roller take place to rotate. When the mounting block slides to enter the limiting groove, the side wall of the mounting block further extrudes the limiting beads, the limiting bead compression springs enter the connecting sleeve until the limiting holes on the mounting block move to the necking position, the elastic force generated by the spring reset pushes the limiting beads out of the connecting sleeve and enters the limiting holes, and the axial fixation of the hairbrush is realized.

The present invention may be further configured in a preferred embodiment as: the end wall of arc wall is followed first arc wall has been seted up to brush roller circumference, install reset spring in the first arc wall, install an arc piece in the first arc wall, the size of arc piece with first arc wall the arc wall size cooperation, set up flutedly on the both sides wall of arc piece, install wedge and first spring in the recess, first spring both ends butt respectively the grooved underside with the wedge.
