Specifically, the cylinder cover 7 is connected with the main cylinder body 1 by a tooth-shaped rolling head ring 72 and is sealed in a self-sealing manner, the cylinder 71 automatically pushes the rolling head ring 72 to rotate for a certain angle, the locking and the unlocking of the cylinder cover 7 and the main cylinder body 1 are completed, and the safety interlocking device is arranged.

Preferably, the partition 32 is a rectangular plate, which is axially disposed in the cloth storage tank 2. The shape of the partition plate 32 is matched with the section of the cloth storage groove 2. The edge of the partition plate 32 is provided with a reinforcing pipe which can improve the deformation resistance of the partition plate 32. The cloth storage groove 2 can be separated by the partition plate 32 matched with the groove body section of the cloth storage groove 2, and the fabric is prevented from being clamped in a gap between the partition plate 32 and the cloth storage groove 2.

Preferably, the cloth storage groove 2 is provided with a semicircular arc groove body, and the inner wall of the groove body is provided with a polytetrafluoroethylene rod or a polytetrafluoroethylene plate.

Preferably, 1, 2, 3, 4, 6 or 8 cloth storage grooves 2 are axially arranged in the main cylinder 1, and each cloth storage groove 2 can independently contain a preset volume of fabrics. The cloth storage groove 2 is respectively provided with a corresponding cloth lifting roller 5, a nozzle 6 and a corner type adjusting plate 3. By providing a different number of the cloth storage tanks 2, a plurality of the same dyeing processes or different kinds of dyeing processes can be performed in parallel.

In order to ensure the smooth rotation of the angle adjusting plate 3 in each cloth storage groove 2, the angle adjusting plates 3 of the adjacent cloth storage grooves 2 are connected through a spherical sliding support seat 9. The rotating device 4 comprises a spherical sliding shaft head 41, a universal coupling 42, a rolling bearing 43, a bearing seat 44, a connecting shaft 45, an elastic coupling 46, a speed reducer 47 and a motor 48, wherein the connecting shaft 45 is arranged on the bearing seat 44 through the rolling bearing 43, one end of the connecting shaft is connected with the spherical sliding shaft head 41 through the universal coupling 42, and the other end of the connecting shaft is connected with the speed reducer 47 and the motor 48 through the elastic coupling 46.

The second embodiment of the invention provides a bidirectional jet dyeing method, which comprises the following steps:

s001, opening a cylinder cover 7, and feeding one end of a fabric 8 into a fabric storage groove 2 through a fabric lifting roller 5;

s002, first half dyeing period: after the fabric is completely fed into the main cylinder body 1, the side with more fabric in the main cylinder body 1 is a lifting area, the side with less fabric is a falling area, and the space corresponding to the lifting area and the falling area in the fabric storage groove 2 is separated by a corner type adjusting plate 3; during the dyeing process, the nozzles 6 located in the drop zone work, and the nozzles 6 located in the lift zone stop working; the fabric is moved from the lifting area to the falling area through the fabric lifting roller 5, and in the moving process of the fabric, the corner adjusting plate 3 swings in the fabric storage groove 2 around a preset swing shaft, so that the sizes of two fabric storage spaces corresponding to the lifting area and the falling area are correspondingly increased and reduced;

s003, a latter half dyeing period: when the fabric of the fabric storage groove 2 falling into the area is increased to a preset value, the fabric lifting roller 5 rotates reversely, the fabric moves reversely, the two nozzles 6 switch the working state, and the corner type adjusting plate 3 swings reversely;

s004, repeating the steps S002 and S003 for a plurality of times until dyeing is completed.

It should be noted that, by the above method, in the whole dyeing period, both ends of the fabric are always in the corresponding fabric storage spaces, and after dyeing is completed, since both ends of the fabric are open, the cylinder cover can be directly opened to grab the fabric on the cloth lifting roller 5, so that the fabric can be simply and integrally pulled out, and full-automatic feeding and discharging can be realized.

Preferably, the angle-adjustable plate 3 is oscillating back and forth at a constant speed between left and right maximum oscillation angles to obtain a first cloth storage space periodically varying from a maximum volume to a minimum volume during the dyeing process of the fabric and a second cloth storage space periodically varying from the minimum volume to the maximum volume at the same time node. For example, when the first cloth storage space is at the maximum volume, in which most of the fabric is accommodated, the first cloth storage space is at the lifting zone, and the cloth lifting roller 5 transfers the fabric from the first cloth storage space to the second cloth storage space. The second stores up the cloth space and is in and falls into the district, and during the fabric slowly falls into the second and stores up the cloth space, at fabric transfer process, the corresponding swing of corner formula regulating plate 3 for the volume that promotes the district reduces gradually, and the volume that falls into the district crescent, guarantees that the proportion of fabric and dyestuff remains stable. As shown in fig. 5, after most of the fabric falls into the second fabric storage space, the fabric lifting roller 5 rotates reversely, the angle adjusting plate 3 swings reversely, and the fabric moves reversely, so that the cycle is repeated for a plurality of cycles until the dyeing process requirement is met.

The invention divides the cloth storage groove 2 into two parts of lifting and falling, can make the dyed fabric perform bidirectional reciprocating stacking, gradually changes the proportion of the volumes of the two parts of the cloth storage groove within the range of 120 degrees of rotation angle, but keeps the total volume unchanged. No cloth ring is needed to be formed, and the cloth feeding and the cloth discharging are simple.

Considering the two ends of the fabric in the length direction, one section of the fabric is required to be reserved for reversing, so that the fabric cannot be dyed. Before the fabric is fed into the main cylinder body, two ends of the fabric can be respectively connected with a fabric guide head (polypropylene fiber or non-dyed textile can be selected), and the fabric can be repeatedly used.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
