Description

Technical Field

[0001] The invention relates to the technical field of brick glazing, and in particular to a closed low-loss brick glazing device. Background Art

[0002] Brick glazing is a key link in the ceramic tile production process. By applying glaze slurry on the surface of the brick, the aesthetics, wear resistance, stain resistance and other properties of the ceramic tile can be increased. Traditional glazing methods mainly include pouring glaze, spraying glaze and throwing glaze. However, in the process of glazing the brick using the above glazing methods, these traditional methods have many problems such as low degree of automation, poor working environment and poor production stability.

[0003] With the development of science and technology, technicians in related fields have also made a lot of optimizations on the brick glazing technology. In order to make a more accurate comparison, a Chinese patent with publication number CN117962087A discloses a ceramic tile glazing device and a glazing method, including a first glazing structure and a second glazing structure. The front end limit of the conduction control structure is installed with a dust collector. The first glazing structure includes a docking duct, and the front end of the connecting control pipe is connected to the docking duct. The driving transmission on the guide belt is provided with a ceramic tile, and the lower end of the ceramic tile is provided with a driven roller, and the lower end of the valve seat is connected to a guide and exhaust spray port.

[0004] When in use, the tiles are first placed on the dust collector, and the lower ends of the tiles are supported and carried by the driven rollers so that they can move together. Then the tiles reach the second glazing structure. At this time, the glaze is introduced through the docking duct, and the glaze is sprayed onto the tiles through the guide spray port. Then the tiles continue to be transported and reach the first glazing structure, where they are glazed by the glazing turntable to complete the work.

[0005] However, the above prior art still has some shortcomings in the process of glazing tiles:

[0006] 1. In the process of glazing tiles, the above-mentioned prior art cannot control the glazing width of the guide spray port on the tiles, so that the glaze that is larger than the width of the tiles cannot be sprayed on the tiles, resulting in a waste of glaze and increased costs.

[0007] 2. A large amount of air will be mixed in during the preparation of the glaze. If it is sprayed directly, the air may form pinholes or bubbles in the glaze layer. However, the above-mentioned existing technology cannot eliminate the bubbles in the glaze, which may easily cause defects on the tile glaze surface and affect the quality of the glaze surface.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-Figure 10 Embodiments of the present invention are described in detail.

[0038] The embodiment of the present application discloses a closed low-loss brick glazing device. It should be noted that the closed low-loss brick glazing device of the present application is mainly used in the process of glazing the surface of the brick. In terms of technical effect, the glazing width can be adjusted according to the width of the brick while fixing the brick, so as to avoid the glazing width being greater than the width of the brick, thereby causing unnecessary loss of glaze and reducing costs; further, the closed low-loss brick glazing device of the present application can also defoam the glaze to avoid the bubbles in the glaze affecting the glazing of the brick.

[0039] Reference Figure 1 As shown, in order to realize the glazing work on the surface of the brick, specifically, this embodiment provides a closed low-loss brick glazing device, including a support frame 1, two support plates 2 symmetrically distributed along the width direction are installed on the upper end of the support frame 1, a reaction barrel 3 is installed on the side of one of the support plates 2 away from the support frame 1, a protection box 4 is commonly arranged on the upper ends of the two support plates 2, a conveyor belt 5 is arranged between the two support plates 2, an aging unit 6 is installed inside the reaction barrel 3, and a glaze spraying unit 7 for spraying glaze on the brick is installed inside the protection box 4.

[0040] Furthermore, in this embodiment, the aging unit 6 includes a stirring rod 65 installed inside the reaction barrel 3, and the glaze spraying unit 7 includes a partition plate 9 installed on the inner wall of the protection box 4, a glaze box 10 for storing raw materials is installed on the upper end of the partition plate 9, a throttling assembly 12 is installed below the partition plate 9, and an opening and closing assembly 14 is arranged inside the glaze box 10.

[0041] In actual application, after the staff adds the glaze and a certain proportion of defoaming agent into the reaction barrel 3, the glaze and the defoaming agent in the reaction barrel 3 are fully stirred by the stirring rod 65, so that the glaze and the defoaming agent can be fully mixed, ensuring that the bubbles inside the glaze can be eliminated under the action of the defoaming agent. At the same time, the stirring rod 65 can also accelerate the elimination of bubbles in the process of stirring the glaze, reduce the aging time of the glaze, and reduce time cost; the aging glaze is transported to the glaze box 10 through the pipeline, and then the brick blank is controlled to move to the lower end of the glaze box 10 by the conveyor belt 5, and the brick blank at the lower end of the glaze box 10 can be sprayed with glaze through the mutual cooperation between the throttling component 12 and the opening and closing component 14, and in the process of spraying glaze, the mutual cooperation between the throttling component 12 and the opening and closing component 14 can save the consumption of glaze to the maximum extent and reduce the cost.

[0042] Reference Figure 1 , Figure 2 and Figure 3 As shown, in order to reduce the aging time of the glaze and increase the aging effect of the glaze, based on this, in the present embodiment, the aging unit 6 also includes a power motor 61 arranged at the upper end of the reaction barrel 3 through a motor seat, and a transmission shaft 62 is installed at the lower end of the output shaft of the power motor 61. The transmission shaft 62 rotates through the reaction barrel 3 at one end away from the power motor 61, and a plurality of parallel rods 63 distributed in a circle are installed on the outer wall of the transmission shaft 62. A connecting ring 64 is installed together at one end of the plurality of parallel rods 63 away from the transmission shaft 62, and a plurality of stirring rods 65 parallel to the axis of the transmission shaft 62 and distributed in a circle are arranged at the lower end of the connecting ring 64.

[0043] Furthermore, in this embodiment, a sliding ring 66 is slidably penetrated through the outer walls of multiple stirring rods 65, and an annular protrusion 661 is provided on the inner and outer walls of the sliding ring 66. A filter plate 67 and a filter ring 68 are rotatably sleeved on the inner and outer walls of the sliding ring 66 respectively. An annular groove 662 is provided on the outer wall of the filter plate 67 and the inner wall of the filter ring 68. The annular protrusion 661 is in rotational contact with the annular groove 662. A plurality of circumferentially distributed aged hydraulic rods 69 are installed on the inner top wall of the reaction barrel 3, and the telescopic end of the aged hydraulic rod 69 is connected to the filter ring 68.

[0044] It should be noted that, since the sliding ring 66 and the stirring rod 65 are slidingly connected, and the sliding ring 66, the filter plate 67 and the filter ring 68 are in a rotating sleeve relationship, the connecting ring 64 rotates and can drive the sliding ring 66 to rotate through the stirring rod 65 during the stirring of the glaze, but will not drive the filter plate 67 and the filter ring 68 to rotate, and will not cause interference between the stale hydraulic rod 69 and the filter ring 68, thereby ensuring that the stale hydraulic rod 69 can smoothly drive the filter plate 67, the sliding ring 66 and the filter ring 68 to move upward.

[0045] In actual application, after the staff adds the glaze and defoamer into the reaction barrel 3, they start the power motor 61, and the power motor 61 drives the transmission shaft 62 to rotate, and the transmission shaft 62 drives the stirring rod 65 to rotate through the cooperation between the parallel rod 63 and the connecting ring 64. The stirring rod 65 can stir the glaze and defoamer in the reaction barrel 3 while rotating, so that the glaze and the defoamer are fully mixed, the aging effect of the defoamer on the glaze is increased, and the aging time is reduced; when the glaze and the defoamer are fully mixed, the connecting ring 64 drives the stirring rod 65 to rotate slowly and continuously stir the glaze, which not only avoids the generation of bubbles, It can also accelerate the elimination of bubbles and further reduce the aging time; when the glaze is aged in the reaction barrel 3, the aging hydraulic rod 69 is started, and the filter ring 68, the sliding ring 66 and the filter plate 67 are driven to move upward by the telescopic end of the aging hydraulic rod 69. The filter ring 68 and the filter plate 67 can filter the glaze and further remove the bubbles inside the glaze during the upward movement, so as to avoid the formation of pinholes and bubbles in the glaze layer when the glaze spraying unit 7 is spraying glaze on the brick blank, thereby affecting the quality of the glaze surface and increasing the subsequent glazing effect on the brick blank; then the glaze filtered at the bottom of the filter plate 67 is extracted and sprayed on the brick blank.

[0046] Reference Figure 1 , Figure 4 and Figure 5 As shown, in order to realize the transportation and glazing of the brick blanks, based on this, in the present embodiment, the power motor 61 is a bidirectional motor, and has an output shaft at both ends. A matching shaft 15 is installed on the upper end of the output shaft of the power motor 61, and a matching bevel gear 21 is sleeved on the outer wall of the matching shaft 15. Linkage shafts 16 are rotatably installed on both side walls of the protection box 4. The outer wall of the linkage shaft 16 away from the protection box 4 is sleeved with a synchronous bevel gear 17 meshing with the matching bevel gear 21, and the outer wall of the linkage shaft 16 close to the protection box 4 is sleeved with an intermittent gear 18. A plurality of equally spaced rotating shafts 19 are rotatably penetrated between the two support plates 2, and the outer wall of the rotating shaft 19 in the middle of the support plate 2 is sleeved with a spur gear 20 meshing with the intermittent gear 18. The outer walls of the plurality of rotating shafts 19 are jointly sleeved with a conveyor belt 5, and the outer wall of the conveyor belt 5 is evenly installed with a plurality of equally spaced resistance blocks 8.

[0047] Furthermore, in this embodiment, the glaze box 10 is connected to the reaction barrel 3 by a pipeline, and a plurality of glazing groups are installed at the lower end of the glaze box 10, each glazing group includes a plurality of glaze spraying cylinders 72 arranged at the lower end of the glaze box 10 and equidistantly distributed along the length direction of the protection box 4, and the plurality of glaze spraying cylinders 72 of two adjacent glazing groups are staggered and offset from each other, and the lower ends of the plurality of glaze spraying cylinders 72 are all provided with elliptical glaze nozzles 73; two resistance plates 74 symmetrically distributed along the width direction of the conveyor belt 5 are arranged above the conveyor belt 5, and a plurality of equidistantly distributed resistance spring rods 75 are commonly installed between the two resistance plates 74 and the inner wall of the protection box 4.

[0048] It should be noted that the intermittent gear 18 is an incomplete gear, which can drive the spur gear 20 to rotate intermittently when it rotates continuously. Therefore, each time the spur gear 20 is driven to rotate once, the conveyor belt 5 controls the brick to move once, and the distance that the conveyor belt 5 controls the brick to move once is the distance between two adjacent resistance blocks 8; the resistance spring rod 75 always pushes the resistance plate 74 toward the side of the resistance block 8, so that the two resistance plates 74 can limit and fix the brick, ensuring that the brick is positioned during the glaze spraying process.

[0049] In actual application, after the aged glaze is transported to the glaze box 10 through the pipeline, the brick is placed above the conveyor belt 5 and located on the side of the abutment block 8 close to the glaze box 10, and then the power motor 61 drives the matching shaft 15 and the matching bevel gear 21 to rotate synchronously, the matching bevel gear 21 drives the synchronous bevel gear 17 meshing therewith to rotate, the synchronous bevel gear 17 drives the intermittent gear 18 to rotate through the linkage shaft 16, the intermittent gear 18 drives the spur gear 20 meshing therewith to rotate intermittently, the spur gear 20 drives the rotating shaft 19 to rotate intermittently, and the rotating shaft 19 drives the conveyor belt 5 through the connecting sleeve. The brick blanks are intermittently rotated, and the conveyor belt 5 is used to control the brick blanks to intermittently move toward the side of the glaze box 10. In the process of moving toward the side of the glaze box 10, the brick blanks gradually come into contact with the resistance plate 74, so that the brick blanks can smoothly move to the bottom of the glaze box 10. During this period, the brick blanks can be corrected by the mutual cooperation between the resistance block 8 and the resistance plate 74 to avoid the brick blanks being tilted, not placed horizontally, etc., which will cause spraying deviation and incomplete spraying, thereby increasing the glazing effect of the brick blanks; when the brick blanks move to the bottom of the glaze box 10, the brick blanks can be sprayed with glaze by the mutual cooperation between the glaze spraying tube 72 and the glaze nozzle 73.

[0050] Reference Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in order to make the glaze nozzle 73 glaze only when there are bricks under the glaze box 10, and to automatically stop glazing after the bricks are glazed, based on this, in the present embodiment, the throttling assembly 12 includes two sliding rods 121 arranged on the two inner walls of the protection box 4 and parallel to its length direction, and a throttling frame 122 is installed on the opposite sides of the two sliding rods 121. The throttling frame 122 is provided with a plurality of throttling plates 123 corresponding to the glaze nozzle 73 on the side close to the glaze nozzle 73, and the glaze nozzle 73 is provided with a valve hole 124 on the side close to the throttling plate 123, and the top wall of the valve hole 124 is provided with an arc groove 125, and an arc block 126 is slidably installed in the arc groove 125, and the lower end of the arc block 126 gradually tilts toward the inner side of the glaze nozzle 73, and the upper edge of the throttling plate 123 is provided with a chamfer for easy insertion into the valve hole 124.

[0051] Furthermore, in the present embodiment, the throttling assembly 12 also includes an arc-shaped shifting bar 127 installed on the side of the intermittent gear 18 away from the protection box 4, and parallel holes 128 are provided on both side walls of the protection box 4 close to the intermittent gear 18. A square rod 129 sliding through the parallel hole 128 is provided on the side of the slide rod 121 close to the protection box 4, and a round rod 130 is installed on the end of the square rod 129 away from the slide rod 121. Damping blocks 131 are provided on the top wall and the bottom wall of the parallel hole 128. A spring groove 132 is provided on the side wall of the parallel hole 128 away from the intermittent gear 18, and an ejection spring 133 and an ejection block 134 are slidably installed in the spring groove 132 from the side away from the square rod 129 to the side close to the square rod 129 in sequence; a sliding groove 135 is provided on the inner side wall of the protection box 4, and a support rod 136 located in the sliding groove 135 is installed on the end of the slide rod 121 away from the square rod 129, and the support rod 136 is in sliding contact with the sliding groove 135.

[0052] It should be noted that the ejection spring 133 always applies an ejection force to the square rod 129 toward the side of the intermittent gear 18, so that the square rod 129 can be reset under the action of the ejection spring 133, thereby closing the glaze nozzle 73 and avoiding unnecessary waste caused by continuous supply of glaze.

[0053] In actual application, when the intermittent gear 18 is separated from the spur gear 20, the arc-shaped bar 127 contacts the circular rod 130, and the circular rod 130 moves toward the side away from the intermittent gear 18 under the action of the arc-shaped bar 127. The circular rod 130 drives the sliding rod 121 to move synchronously toward the side away from the intermittent gear 18 through the square rod 129. The two sliding rods 121 jointly drive the throttle frame 122 to move toward the side away from the intermittent gear 18. The throttle frame 122 drives all the throttle plates 123 to move synchronously, so that the throttle plate 123 is separated from the valve hole 124, thereby realizing the opening of the glaze nozzle 73, so that the glaze nozzle 73 can smoothly glaze the brick blank; when the throttle plate 123 is separated from the valve hole 124, the arc-shaped block 126 moves downward under the action of gravity to close the valve hole 124, so as to prevent the glaze from flowing out of the valve hole 124 and affecting the glazing of the brick blank, while reducing the consumption of glaze, increasing the glazing effect of the brick blank and reducing the cost.

[0054] During the process of glazing the brick by the glaze nozzle 73, the square rod 129 moves toward the side close to the intermittent gear 18 under the action of the ejection spring 133 and the ejection block 134, and the square rod 129 drives the slide bar 121 and the throttle frame 122 to move synchronously, and the throttle frame 122 drives the throttle plate 123 to move toward the side close to the glaze nozzle 73. At the same time, the moving speed of the square rod 129, the slide bar 121 and the throttle frame 122 can be delayed by the damping block 131, so as to ensure that the glaze nozzle 73 has enough time to glaze the brick and increase the glazing effect of the brick. When the square rod 129 leaves the area of ​​the damping block 131, the square rod 1 29 moves rapidly toward the side close to the intermittent gear 18 under the action of the ejection spring 133 and the ejection block 134. During this period, the throttle plate 123 gradually contacts with the arc block 126 and squeezes the arc block 126 upward, so that the throttle plate 123 can smoothly enter the valve hole 124, so that the throttle plate 123 can quickly close the glaze nozzle 73. When the next brick moves to the bottom of the glaze box 10, the arc strip 127 contacts with the round rod 130 again, and then opens the glaze nozzle 73, so as to realize the precise positioning and glazing of the brick by the glaze nozzle 73, avoid unnecessary consumption of glaze and reduce costs.

[0055] Reference Fig. 9 and Fig.10As shown, in order to enable the glaze nozzle 73 to automatically adjust the glazing width according to the width of the brick blank, avoid the glazing width being greater than the width of the brick blank, thereby causing unnecessary waste of glaze, based on this, in this embodiment, the opening and closing component 14 includes two telescopic opening and closing plates 141 arranged on the inner bottom wall of the glaze box 10 and symmetrically distributed along its width direction, the opposite sides of the two telescopic opening and closing plates 141 are slidably connected, and the opposite sides of the two telescopic opening and closing plates 141 are installed with opening and closing ropes 142, and the opening and closing ropes 142 are passed through the glaze nozzle 73 in sequence away from the end of the telescopic opening and closing plate 141. The box 10 and the partition plate 9 are connected to the square block 143 at the back, and the square block 143 is installed on the upper end of the contact plate 74. The outer wall sliding sleeve of the opening and closing pull rope 142 is provided with a limiting cylinder 144 located at the lower end of the partition plate 9, and a connecting block 145 for fixing the limiting cylinder 144 is installed at the lower end of the partition plate 9. The connecting block 145 is connected to the limiting cylinder 144 at one end away from the partition plate 9; the inner bottom wall of the glaze box 10 is installed with two closing blocks 146 distributed symmetrically along its length direction, and a closing spring rod 147 is arranged between the closing block 146 and the telescopic opening and closing plate 141.

[0056] It should be noted that the closing spring rod 147 always applies a contraction force to the telescopic opening and closing plate 141 pointing to the middle side of the glaze box 10, so as to ensure that the telescopic opening and closing plate 141 can be smoothly reset; the path of the opening and closing pull rope 142 can be limited by the limiting cylinder 144 to avoid interference between the opening and closing pull rope 142 and other components.

[0057] In actual application, when the conveyor belt 5 controls the brick to move under the glaze box 10, the brick gradually contacts the contact plate 74 and under the action of the conveyor belt 5 and the contact block 8, the contact plate 74 moves close to the inner wall of the protection box 4. When the distance between the two contact plates 74 is the same as the width of the brick, the two contact plates 74 stop moving toward the inner wall of the protection box 4, and the brick moves from between the two contact plates 74 to under the glaze box 10. During this period, the two contact plates 74 drive the two telescopic opening and closing plates 141 to move close to both sides of the intermittent gear 18 through the opening and closing pull ropes 142. The moving distance of the two telescopic opening and closing plates 141 is the same as the width of the brick, so as to open the glaze spraying cylinder 72 corresponding to the width of the brick; because the telescopic opening and closing plates 141 are slidably connected to the glaze The inner bottom wall of the material box 10, so the glaze spraying tube 72 installed on the inner bottom wall of the glaze box 10 can be closed by the telescopic opening and closing plate 141, so as to prevent the glaze inside the glaze box 10 from entering the glaze spraying tube 72, and the telescopic opening and closing plate 141 has a plurality of slidingly connected telescopic joints, and the plurality of telescopic joints have elastic force expanding outward, so when the opening and closing pull rope 142 applies tension to the telescopic opening and closing plate 141, the telescopic joints closest to the opposite sides of the two telescopic opening and closing plates 141 are first moved to open the corresponding number of glaze spraying tubes 72, so that the glaze enters, and the glazing width of the glaze spraying tube 72 is consistent with the width of the brick, so as to avoid the waste of glaze and reduce the cost; during this period, the other telescopic joints remain stationary under the action of the elastic force and always seal the unopened glaze spraying tube 72.

[0058] It should be noted that the bottom of the multiple telescopic joints of the telescopic opening and closing plate 141 provided in this embodiment are all equipped with sealing pads that are in sliding contact with the inner bottom wall of the glaze box 10, so as to compensate for the gap between the telescopic opening and closing plate 141 and the inner bottom wall of the glaze box 10, thereby ensuring the sealing effect of the glaze spraying cylinder 72.

[0059] During operation: Step 1: After the staff adds the glaze and the defoamer into the reaction barrel 3, the power motor 61 is started, and the transmission shaft 62 is driven to rotate by the power motor 61. The transmission shaft 62 drives the stirring rod 65 to rotate through the cooperation between the parallel rod 63 and the connecting ring 64. The stirring rod 65 can stir the glaze and the defoamer in the reaction barrel 3 while rotating, so that the glaze and the defoamer are fully mixed; when the glaze and the defoamer are fully mixed, the connecting ring 64 drives the stirring rod 65 to rotate slowly and continuously stir the glaze, which not only avoids the generation of gas Bubbles can also be accelerated to eliminate bubbles; when the glaze is aged in the reaction barrel 3, the aging hydraulic rod 69 is started, and the filter ring 68, the sliding ring 66 and the filter plate 67 are driven to move upward by the telescopic end of the aging hydraulic rod 69. The filter ring 68 and the filter plate 67 can filter the glaze and further remove the bubbles inside the glaze during the upward movement, so as to avoid the formation of pinholes and bubbles in the glaze layer when the glaze spraying unit 7 is spraying glaze on the brick blank, thereby affecting the quality of the glaze surface; then the glaze filtered at the bottom of the filter plate 67 is extracted and sprayed on the brick blank.

[0060] Step 2: After the aged glaze is transported to the glaze box 10 through the pipeline, the brick is placed above the conveyor belt 5 and located on the side of the abutment block 8 close to the glaze box 10. Then, the power motor 61 drives the matching shaft 15 and the matching bevel gear 21 to rotate synchronously. The matching bevel gear 21 drives the synchronous bevel gear 17 meshing therewith to rotate. The synchronous bevel gear 17 drives the intermittent gear 18 to rotate through the linkage shaft 16. The intermittent gear 18 drives the spur gear 20 meshing therewith to rotate intermittently. The spur gear 20 drives the rotating shaft 19 to rotate intermittently. The rotating shaft 19 drives the conveyor through the connecting sleeve. The belt 5 rotates intermittently, and the conveyor belt 5 controls the brick blank to intermittently move toward the side of the glaze box 10. The brick blank gradually contacts the contact plate 74 during the movement toward the side of the glaze box 10, so that the brick blank can smoothly move to the bottom of the glaze box 10. During this period, the brick blank can be corrected by the mutual cooperation between the contact block 8 and the contact plate 74 to avoid the brick blank being tilted, not placed horizontally, etc., which may cause spraying deviation and incomplete spraying; when the brick blank moves to the bottom of the glaze box 10, the glaze spraying tube 72 and the glaze nozzle 73 can be used to spray glaze on the brick blank through the mutual cooperation between the glaze spraying tube 72 and the glaze nozzle 73.

[0061] Step 3: When the intermittent gear 18 is separated from the spur gear 20, the arc-shaped bar 127 contacts the circular rod 130, and the circular rod 130 moves toward the side away from the intermittent gear 18 under the action of the arc-shaped bar 127. The circular rod 130 drives the sliding rod 121 to move synchronously toward the side away from the intermittent gear 18 through the square rod 129. The two sliding rods 121 jointly drive the throttle frame 122 to move toward the side away from the intermittent gear 18. The throttle frame 122 drives all the throttle plates 123 to move synchronously, so that the throttle plate 123 is separated from the valve hole 124, thereby realizing the opening of the glaze nozzle 73; when the throttle plate 123 is separated from the valve hole 124, the arc-shaped block 126 moves downward under the action of gravity to close the valve hole 124, so as to prevent the glaze from flowing out of the valve hole 124 and affecting the glazing of the brick, and at the same time reduce the consumption of glaze.

[0062] When the glaze nozzle 73 is glazing the brick, the square rod 129 moves toward the side close to the intermittent gear 18 under the action of the ejection spring 133 and the ejection block 134, and the square rod 129 drives the slide bar 121 and the throttle frame 122 to move synchronously, and the throttle frame 122 drives the throttle plate 123 to move toward the side close to the glaze nozzle 73. At the same time, the damping block 131 can slow down the movement speed of the square rod 129, the slide bar 121 and the throttle frame 122, so as to ensure that the glaze nozzle 73 has enough time to glaze the brick; when the square rod 129 leaves the area of ​​the damping block 131, The square rod 129 moves rapidly toward the side close to the intermittent gear 18 under the action of the ejection spring 133 and the ejection block 134. During this period, the throttle plate 123 gradually contacts the arc block 126 and squeezes the arc block 126 upward, so that the throttle plate 123 can smoothly enter the valve hole 124, so that the throttle plate 123 can quickly close the glaze nozzle 73. When the next brick moves to the bottom of the glaze box 10, the arc strip 127 contacts the round rod 130 again, and then opens the glaze nozzle 73, so as to achieve precise positioning and glazing of the brick by the glaze nozzle 73.

[0063] Step 4: When the conveyor belt 5 controls the brick to move under the glaze box 10, the brick gradually contacts the contact plate 74 and under the action of the conveyor belt 5 and the contact block 8, the contact plate 74 moves close to the inner wall of the protection box 4. When the distance between the two contact plates 74 is the same as the width of the brick, the two contact plates 74 stop moving toward the inner wall of the protection box 4, and the brick moves from between the two contact plates 74 to the bottom of the glaze box 10. During this period, the two contact plates 74 drive the two telescopic opening and closing plates 141 to move close to both sides of the intermittent gear 18 through the opening and closing pull ropes 142. The moving distance of the two telescopic opening and closing plates 141 is the same as the width of the brick, so as to open the glaze spraying cylinder 72 corresponding to the width of the brick; due to the sliding of the telescopic opening and closing plates 141 It is movably connected to the inner bottom wall of the glaze box 10, so the glaze spraying tube 72 installed on the inner bottom wall of the glaze box 10 can be closed by the telescopic opening and closing plate 141 to prevent the glaze inside the glaze box 10 from entering the glaze spraying tube 72, and the telescopic opening and closing plate 141 has a plurality of slidingly connected telescopic joints, and the plurality of telescopic joints have elastic force expanding outward, so when the opening and closing pull rope 142 applies tension to the telescopic opening and closing plate 141, the telescopic joints closest to the opposite sides of the two telescopic opening and closing plates 141 are first moved to open the corresponding number of glaze spraying tubes 72, so that the glaze enters, and the glazing width of the glaze spraying tube 72 is consistent with the width of the brick; during this period, the other telescopic joints remain stationary under the action of the elastic force and always seal the unopened glaze spraying tube 72.
