Referring to fig. 6, the rope 8 facing the space has the effect that the parison tube not in contact with the roller tube is in contact with the roller tube in advance, and after the parison tube is in contact with the roller tube for a certain length, the negative pressure acting on the parison tube is generated by extruding the rope 8, so that the negative pressure acting range is wider, and blank areas are avoided.

With reference to the above description, the specific configurations of the roller tube and the suction and discharge member in the present embodiment will be described:

referring to fig. 5, the roller tube includes a sleeve 53 and a plurality of tube slots 51 arranged outside the sleeve 53, and through holes communicating with adjacent suction and discharge members are formed in the plurality of tube slots 51.

As for the suction and discharge member, please refer to fig. 5-9, which includes a porous block mounting box 55 disposed in the casing 53, wherein a mating hole communicating with the adjacent through hole is formed on one surface of the porous block mounting box 55 contacting the casing 53;

it should be noted that the mating holes coincide with and correspond to the perforations;

the porous block mounting box 55 is internally provided with a porous block 56, two sides of the porous block 56 are respectively provided with a sliding block 57 which is matched with the porous block mounting box 55 in a sliding way, the sliding block 57 is a connecting end of the rope 8, one side of the sliding block 57, which is back to the porous block 56, is provided with a spring 58 which is sleeved on the rope 8, and the end part of the spring 58 is abutted against the sliding block 57 and the porous block mounting box 55, so that when the sliding block 57 is abutted against or away from the porous block 56, positive pressure or negative pressure is generated in the through hole and the matching hole.

In the present embodiment, the rope 8 is kept at a distance from the roller tube in the length direction of the roller tube, and accordingly, in order to maintain the distance, please refer to fig. 5 and 6, a plurality of rope lifting portions facing to the interval are arranged outside the sleeve 53, the rope lifting portions comprise rope threading plates 54 mounted near the ends of the sleeve 53 and a plurality of baffles 52 positioned between the rope threading plates 54, wherein the rope threading plates 54 are internally provided with rope passages for lifting the rope 8, the baffles 52 are provided with open rope threading spaces, and the baffles 52 are fixed at the intervals between the adjacent pipe grooves 51 for exposing the rope 8 to the outside of the pipe grooves 51 after passing through the plurality of baffles 52.

The working principle of the glass fiber sleeve dip-coating equipment is explained in combination with the explanation:

the parison tube is wound into the tube slot 51 from the bottom of the sleeve 53, and accordingly, the sleeve 53 rotates to make the plurality of strings 8 positioned outside the sleeve 53 alternately contact the parison tube, so that when the parison tube presses the strings 8 in contact with the parison tube, the slide block 57 connected with the strings 8 moves linearly in the porous block mounting box 55 away from the porous block 56, and negative pressure is generated in the porous block 56, the negative pressure is intensively acted on the through holes and the matching holes, so that the parison tube positioned in the range of the porous block mounting box 55 can receive the negative pressure (the parison tube wound into the tube slot 51 tends to block the through holes, and in addition, the parison tube made of glass fiber has certain air permeability, therefore, the dip-coating material can rapidly penetrate through the parison tube during the action of the negative pressure), and the dip-coating material can rapidly penetrate into the parison tube under the action of the negative pressure.

Of course, the application of negative pressure to the parison tube is only a part of the entire dip coating operation, that is, when the string 8 rotates to a position where the parison tube cannot contact, the pressing force of the string 8 by the parison tube pressing by the spring 58 in the porous block mounting box 55 disappears, and then the spring 58 quickly releases the long-time pressing elastic force to make the slider 57 move linearly toward the porous block 56, thereby generating positive pressure in the porous block 56, which acts intensively on the through hole and the mating hole, so that the parison tube which is about to be away from the porous block mounting box 55 can receive the positive pressure, and the dip coating material which enters the porous block 56 under the negative pressure acts on the parison tube in an impact manner, thereby accelerating the dip coating material to penetrate the parison tube.

In the present embodiment, the rope lifting portion has another function, that is, the rope lifting portion protrudes outward than the sleeve 53, and thus, when the sleeve 53 rotates, the rope lifting portion protruding outward can effectively stir the dip coating material placed in the hopper 1, so as to prevent the dip coating material with a poor flow coefficient from hardening and the like.

In this embodiment, the wetting roller 5 is driven to rotate by a motor (not shown in the drawings).

In this embodiment, workbin 1 includes case body 11 and is located the intermediate layer 12 of soaking 5 tip both sides of roller, be equipped with in the intermediate layer 12 with soak 5 roller directly link and the rotation of roller fixed to 11 department drive wheels 6 of case body, in view of the above, arrange two first rollers 2 in workbin 1 top, two first rollers 2 are including the rotatory roller body 21 that sets up in frame 4 department, roller body 21 is parallel with soak 5 roller, and roller body 21 department installs the power of getting wheel 22, the power of getting wheel 22 passes through belt 7 and is connected with the transmission of drive wheel 6 transmission.

It should be noted that, the force taking wheel 22 installed at the roller body 21 near the first frame opening is rotatably connected with the roller body 21, and the force taking wheel 22 installed at the roller body 21 near the second frame opening is fixedly connected with the roller body 21, so that the driving wheel 6 is directly connected with the soaking roller 5 to obtain the torque force, so that the roller body 21 near the second frame opening obtains the torque force and reversely rotates relative to the soaking roller 5, and the roller body 21 near the first frame opening does not obtain the torque force of the soaking roller 5.

It is to be noted that the parison tube enters the frame 4 through the first frame opening and exits through the second frame opening.

Referring to fig. 1-4, in the present embodiment, a plurality of second rollers 3 are further disposed in the frame 4 near the first frame opening.
