When the mould release agent is used, firstly, the mould release agent is filled in the box 11, the mould release agent is generally sticky, and under the action of gravity, the mould release agent can enter the cavity 12 along the filter screen 13 between the box 11 and the cavity 12; because the semicircular templates are generally placed with the arc surfaces facing downwards, the inner side surfaces of the templates face upwards; when the smearing is needed, firstly, the scraping plates 8 and the smearing plates 10 at the end parts of the two supporting rods 7 are rotated; the scraper 8 facing one side of the advancing direction faces downwards, and the smearing plate 10 on the other side faces downwards (when moving from left to right in the attached drawings 1-3, the scraper 8 on the right side faces downwards, and the smearing plate 10 on the left side faces downwards); the entire device is then placed inside the formwork, see fig. 1-3, with the front and rear sleeves 2 having the pulleys 24 clamped on the edges of the two sides of the semicircular formwork, and then the handle 31 is held by hand and the entire box 11 is pressed down, so that the wheels 5 are in full contact with the ground, and the scraper 8 and the applicator plate 10 can also be in full contact with the inner side of the formwork, while the plurality of nozzles at the ends of the hollow tubes 16 can also be pressed against the inner side of the formwork.

In the initial position, the squeegee 8 and the applicator plate 10 are on opposite sides of the stencil and are aligned with the edges of the stencil, with the two struts 7 forming an angle of 170 degrees (depending on the width of the squeegee 8 and the applicator plate 10).

When the painting is started, the whole device is translated rightwards from the left end of the template along the length direction of the template, in the translation process, firstly, a plurality of wheels 5 can simultaneously rotate in the same direction, and a rotating shaft 3 in a sleeve 2 is driven to rotate through a belt and a belt pulley, after the rotating shaft 3 rotates, the rotating shaft 3 can drive a second bevel gear 19 to rotate through a first bevel gear 17, then the incomplete gear 20 is driven to rotate through a short shaft 18, and when a toothed part of the incomplete gear 20 rotates to be meshed with a gear on a left transverse shaft 6, the left transverse shaft 6 can be driven to rotate; the left transverse shaft 6 and the right transverse shaft 6 are linked through a third bevel gear 22 and two fourth bevel gears 23 which are sleeved on the rotating shaft 3; therefore, the left and right transverse shafts 6 can synchronously and reversely rotate; moreover, the third bevel gear 22 and the rotating shaft 3 are mounted through a bearing, so that the rotation of the rotating shaft 3 is not influenced; therefore, when the left transverse shaft 6 swings from back to front, the right rotary shaft 3 swings from front to back, a crossed motion mode is realized, and the unstable phenomenon caused by the same-direction swinging can be reduced.

Scraper blade 8 on right side and left smearing plate 10 are swung to the in-process of offside by initial horizontal position, can clear the template and scrape and smear, after scraper blade 8 and smearing plate 10 swung the offside respectively, the non-tooth portion of incomplete gear 20 on the minor axis 18 this moment can contact with the gear on the pivot 3 of left side, thereby make left cross axle 6 lose power, the cross axle 6 of the left and right sides can be under the effect of reset torsion spring 21 this moment, reverse rotation once more, resume to initial state, thereby realized again and clearly scraping and smearing the template.

Because the whole device is translated from left to right, and the end part of the right supporting rod 7 is provided with the scraper 8, when the scraper 8 moves, the scraper 8 on the right side can scrape the inner side surface of the template, so that dust or sundries adhered to the surface can be scraped off, and the left smearing plate 10 can be smeared conveniently; realizing the mutual matching movement; at the same time, since the spray head is in the middle of the housing 1, i.e. between the right-hand scraper 8 and the left-hand applicator plate 10, the movements of both are not disturbed. When the device needs to move from right to left, the smearing plate 10 at the end of the right-side supporting rod 7 can be downward, and the scraper 8 at the end of the left-side supporting rod 7 can be downward, so that the scraping from right to left can be realized, and the principle is consistent with the process.

In the process that the scraping plate 8 and the smearing plate 10 synchronously and reversely swing, the transverse shaft 6 can also reciprocate, and the transverse shaft 6 on the left side and the disc 14 are linked through a belt and a belt pulley, so that the disc 14 can also reciprocate; referring to fig. 6, since the plurality of radial baffles 15 are installed on the disc 14, the baffles 15 can extend and contract, and the interval between the disc 14 and the cavity 12 is sequentially reduced from top to bottom, during the rotation of the disc 14, the baffles 15 drive the release agent to move downwards, and the space of the release agent is gradually reduced, so as to extrude the release agent, and the release agent is extruded into the hollow pipe 16 through the plurality of pipelines and enters the spray head along the hollow pipe 16; because the end of the spray head is provided with the balls 26, the release agent can be coated on the inner side surface of the template along with the rolling of the balls 26, and because the hollow pipes 16 are provided with a plurality of hollow pipes and face different angles, the uniform coating can be realized, and after the release agent flows into the inner side surface of the template, the inner side surface of the template can be uniformly coated with a layer of release agent under the repeated scraping action of the coating plate 10.

Because the cross shaft 6 is reciprocating rotation in this device, consequently scraper blade 8 and daub board 10 are reciprocating swing, have guaranteed that scraper blade 8 and daub board 10 all swing in the inside of template, can not break away from the template and move, have realized the perfect adaptation to semi-circular template, have avoided excessive swing, and the swing is not enough, and is with strong points.

Although the scraping plate 8 and the smearing plate 10 are both reciprocated and swept and smeared in the horizontal moving process, because the scraping plate 8 and the smearing plate 10 both have certain lengths, an overlapping area exists in the swinging process every time, and the condition of scraping omission or smearing omission is avoided; realize all-round clear scraping and scribbling.

After one of the templates is coated, the next coating can be continuously carried out simply and quickly by only checking the content of the release agent in the box 11 and supplementing the release agent in time.

In the device, the clearance between the disc 14 and the cavity 12 is bilaterally symmetrical and is sequentially reduced from high to low, so that the release agent can be extruded no matter the disc 14 rotates forwards or backwards, and the continuous supply of the release agent is ensured.

The device can realize the effects of scraping and smearing at one time by placing the whole device in the whole template in a horizontal moving mode, has strong pertinence, can exactly cover the semicircular template, and cannot cause throwing and flying of the release agent and waste; the operation is simple, and the working efficiency is improved.

This device does not need extra power supply, through promoting whole device, utilizes wheel 5 to carry out power transmission, has realized the swing of cross axle 6 to and the automation of release agent is extruded, mutually supports between a plurality of moving parts, has accomplished whole process jointly.

The device realizes the reverse synchronous movement of the scraper 8 and the smearing plate 10 by the common matching of a plurality of bevel gears, the incomplete gear 20, the reset torsion spring 21 and the like, balances the stress and avoids the inclination.

In this device, owing to install telescopic link 30 between two connecting rods 4 about, consequently can increase the frictional force between wheel 5 and the ground on the one hand, on the other hand can adapt to the semicircular template of different diameters, simultaneously because the tip of two spinal branch poles 7 all overlaps and is equipped with extension spring 28, consequently also can realize inseparable contact to the medial surface of the semicircular template of different diameters.

In this device, because the position of the scraper blade 8 of the branch 7 tip of left and right sides and daub board 10 can be exchanged to the shower nozzle is in position between the two, consequently after changing 8 and the relative position of daub board 10 of scraper blade, can realize working from a left side to a right side or work from a right side to a left side, be favorable to when carrying out batch daub, reduce reciprocal movement number.
