Description

Technical Field

[0001] The present invention relates to the field of tile production, and particularly to a powder cloth-feeding device for textured tiles. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the appearance of tiles, and some textured tiles are deeply loved by people. When producing tiles with continuous textures, in order to make the continuous textures natural, the outlet of the cloth-feeding cavity is usually arranged above the receiving belt. However, in the application document with the patent number CN102310477B, there is a certain height between the hopper and the receiving belt. When there is a height difference between the hopper and the belt as in this patent, the powder will have a downward impact force during the falling process, causing the textured powder to be scattered and chaotic, resulting in unclear textures in some parts of the tile surface.

[0003] Therefore, the prior art still needs to be improved and developed. Summary of the Invention

[0004] The present invention discloses a powder cloth-feeding device for textured tiles, which is used to improve the problem that the textured powder is scattered and chaotic due to the impact force when the powder falls.

[0010] A linear driver installed on the fixed seat; and

[0011] A gate structure installed at the output end of the linear driver for opening and closing the lower opening;

[0012] A belt driven by a motor is arranged below the gate structure, and the belt can be relatively close to or far from the preforming hopper. During cloth-feeding, the belt is parallel and close to the gate structure.

[0013] Preferably, the gate structure includes a frame body and a gate plate. The frame body is used for connecting with the output end of the linear driver, the gate plate is installed on the frame body, the gate plate is a thin plate, and

[0014] the gate plate is parallel and close to the belt.

[0017] Preferably, the preformed hopper includes a front plate, a back plate and two side plates. The front plate is parallel to and opposite to the back plate, and the two side plates are respectively installed on both sides of the front plate and the back plate.

[0018] Preferably, the preformed hopper further includes a baffle, and the baffle is installed at the bottom of the back plate.

[0019] Preferably, the powder feeding device further includes a movable side baffle. The side baffle is installed on the preformed hopper and is used to prevent powder from leaking from the side of the preformed hopper and to adjust the width of the feeding.

[0020] 5Preferably, the gate structure further includes a cross beam, and the cross beam is installed on the preformed hopper.

[0021] The fixed seat is installed on the cross beam.

[0022] Preferably, the thicknesses of the bottom of the front plate and the back plate gradually decrease from top to bottom.

[0023] Preferably, the powder feeding device further includes a blanking plate. The blanking plate is arranged on the discharging side of the belt. One side of the blanking plate is closely attached to the belt and the blanking surface of the blanking plate is tangent to the belt.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] A powder feeding device for textured tiles provided by the present invention, by arranging a gate structure driven by a linear driver below the preformed hopper, and arranging a belt driven by a motor parallel and closely below the gate structure, so that the powder falling at the gate structure will not be scattered due to the action of gravity, ensuring that the texture of the powder is continuous and natural.

[0026] In addition, a thinner shutter is installed on the frame, so as to ensure that the shutter can maintain its own shape when the linear driver drives the shutter. By slidably connecting the frame to the fixed seat, the shutter is more stable during operation. By providing through holes in the shutter, a pile of powder on the shutter can fall, thereby avoiding the influence on powder feeding caused by the large block of powder piled up on the shutter and falling.

[0027] Moreover, by arranging a gate structure driven by a linear driver below the preformed hopper and arranging a belt driven by a motor parallel and closely below the gate structure, the powder falling at the gate structure will not be scattered due to the action of gravity, ensuring that the texture of the powder is continuous and natural.

[0028] In addition, by installing a thinner shutter on the frame, it is ensured that the shutter can maintain its own shape when the linear driver drives the shutter. By slidably connecting the frame to the fixed seat, the shutter is more stable during operation. By providing through holes in the shutter, a pile of powder on the shutter can fall, thereby avoiding the influence on powder feeding caused by the large block of powder piled up on the shutter and falling.

[0029] The preformed hopper is composed of a front plate, a back plate and two side plates, which facilitates the processing and assembly of the preformed hopper and is easy to disassemble for cleaning and maintenance. By setting a baffle, the powder will not fall downstream of the conveyor belt and affect the subsequent cloth laying. By setting side stop strips on the preformed hopper, it is possible to prevent the powder from leaking out from the bottom side of the preformed hopper and adjust the cloth laying width. By setting a cross beam, it is possible to avoid the frequent cleaning of the gate structure from affecting the structural stability of the preformed hopper. By setting a blanking plate, the powder on the belt can be completely transferred. By gradually reducing the bottom thickness of the front plate and the back plate from top to bottom, the contact area between the preformed hopper and the powder is reduced, ensuring the cloth laying quality.

[0048] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0049] Embodiment

[0050] With the improvement of living standards, people have new requirements for the beauty of home decoration. For example, some user groups prefer textured tiles for home decoration.

[0051] When producing tiles with continuous textures, in order to make the textures continuous and natural, the lower opening of the fabric chamber is usually set above the receiving belt. However, there is a relatively high distance between the hopper and the receiving belt in the prior art. During the falling process of the powder, there will be a downward impact force. After the powder has fallen this height, the textured powder pre-placed in the hopper will be scattered and disordered on the receiving belt. The tiles formed after pressing such powder have unclear and discontinuous textures.

[0052] In order to make the textures of the pressed tiles continuous and clear, the present invention discloses a fabricating device for tile powder. The gate plate of the fabricating device is parallel and close to (close to) the receiving belt, so that the falling distance of the powder is short, avoiding the texture disorder of the powder due to the impact of gravity during falling, and enabling the textures of the tiles to remain continuous after pressing.

[0053] Specifically, referring to Figure 1 and Figure 5-6, the powder feeding device for the textured tile disclosed in the present invention includes a preforming hopper 10. The preforming hopper 10 includes an upper opening 11 and a lower opening 12. The preforming hopper 10 is arranged below the pre - arranged feeding device and is used to receive powders 50 of different colors. And the powders 50 of different colors are formed in the preforming hopper 10. A switch unit 20 is arranged at the lower opening 12 below the preforming hopper 10. The switch unit 20 includes a fixed seat 21, a linear driver 22 and a gate structure 23. Among them, the fixed seat 21 is fixedly connected to the side wall of the bottom of the preforming hopper 10. The linear driver 22 is installed on the fixed seat 21. The gate structure 23 is installed at the output end of the linear driver 22. And the gate structure 23 opens or closes the lower opening 12 of the preforming hopper 10 along with the drive of the linear driver 22. A belt 30 driven by a motor is arranged below the gate structure 23. During the feeding process, the belt 30 is parallel to and close to (adheres to) the gate structure 23. And the part of the gate structure 23 used to close the preforming hopper 10 is a thin plate. When the gate structure 23 is opened along with the linear driver 22, in the case where the falling distance of the powder 50 is extremely short, the powder 50 in the preforming hopper 10 will not be scattered due to impact, thus ensuring that the tiles after production have continuous textures.

[0054] Combined with Figure 5 and Figure 1 , to enable the gate structure 23 and the preforming hopper 10 to be stably connected, usually two fixed seats 21 are provided. The two fixed seats 21 are respectively installed on both sides of the preforming hopper 10.

[0055] Similarly, linear drivers 22 are arranged on both fixed seats 21 on both sides. The gate structure 23 can be stably driven to move under the drive of the two linear drivers 22.

[0056] The upper opening 11 of the preforming hopper 10 gradually narrows from top to bottom. The larger upper opening 11 ensures that the powder 50 in the upper feeding device above can all enter the preforming hopper 10.

[0057] In an embodiment of the present invention, the linear driver 22 can be one of a cylinder, a linear motor or a lead screw structure. Usually, to enable the gate structure 23 to be quickly opened so that the powder 50 on the bottom surface of the preforming hopper 10 can fall almost simultaneously, preferably, in an embodiment of the present invention, the linear driver 22 is selected as a cylinder.

[0058] Combined with Figure 5 and Figure 6The gate structure 23 is used to seal the powder 50, and a thin plate is required to be used, so that the powder 50 falls as short as possible. In order to improve the strength of the gate structure 23, the gate structure 23 includes a frame 231 and a gate plate 232, wherein the frame 231 is provided with connecting parts 2313 on both sides, and the connecting parts 2313 on both sides are respectively connected to the linear drive 22 on both sides of the preforming bucket 10, and the gate plate 232 is installed on the frame 231. When the linear drive 22 drives the frame 231 to move, the gate plate 232 moves synchronously with the frame 231. The gate plate 232 is a thin plate, and the gate plate 232 is parallel to and close to the belt 30.

[0059] Reference Figure 6 The gate plate 232 is an "L"-shaped thin plate, the frame 231 is a "匚"-shaped frame, and the frame 231 includes a horizontal bar 2311 and a vertical bar 2312. Two vertical bars 2312 are provided and fixedly connected to both ends of the horizontal bar 2311. The vertical part of the thin plate is fixedly connected to the horizontal bar 2311, and the connecting part 2313 is installed on the vertical bar 2312, and the connecting part 2313 is connected to the output end of the cylinder.

[0060] Preferably, in one embodiment of the present invention, in order to make the assembly of the output end of the cylinder and the connecting portion 2313 simpler, a fisheye bearing is provided at the connection, and the output end of the cylinder is connected to the fisheye bearing.

[0061] Reinforcing ribs 2314 are provided at the middle and connecting corners on both sides of the frame 231 to stabilize the frame 231 during movement.

[0062] Preferably, in one embodiment of the present invention, a slide groove 211 is provided on the mounting frame, and a slide rail 2315 is provided on the corresponding vertical rod 2312. The slide groove 211 is adapted to the slide rail 2315, that is, the frame 231 is slidably connected to the fixed seat 21. When the linear drive 22 drives the frame 231 to drive the gate plate 232 to move, the frame 231 slides smoothly along the slide groove 211 on the mounting seat, and at the same time, the load on the cylinder is also reduced.

[0063] Reference Figure 2-3 The preforming bucket 10 includes a front plate 13, a back plate 14 and two side plates 15. The front plate 13 is parallel to the back plate 14 and the two are arranged opposite to each other. The two side plates 15 are respectively installed on both sides of the front plate 13 and the back plate 14. The top and bottom of the front plate 13 and the back plate 14 are not connected, and an upper opening 11 and a lower opening 12 are formed above and below the front plate 13 and the back plate 14.

[0064] Since both the front plate 13 and the back plate 14 are straight plates, in order to make the upper opening 11 of the preformed hopper 10 gradually decrease from top to bottom, a material receiving plate 18 is provided above the front plate 13 and the back plate 14. The material receiving plate 18 is installed above the front plate 13 and the back plate 14, and the opening above the material receiving plate 18 is larger than the opening below.

[0065] Referring to Figure 1 and Figure 7 , since the preformed hopper 10 is a combination of a glass / or acrylic panel and an aluminum profile, it is usually not disassembled or assembled after assembly to avoid damaging the profile groove. And a chute 211 is provided on the mounting seat. The mounting seat works in a high-dust environment and needs to be routinely disassembled or cleaned to ensure that the chute 211 can work properly. In order to prevent the disassembly and assembly of the mounting seat from interfering with the preformed hopper 10, a cross beam 233 is provided between the preformed hopper 10 and the mounting seat. The cross beam 233 is fixedly connected to the preformed hopper 10, and the mounting seat is installed on the cross beam 233. When the mounting seat is disassembled and assembled, it will not affect the preformed hopper 10.

[0066] As Figure 3 shown, the powder feeding device further includes side baffle strips 17, and the side baffle strips 17 are installed on the preformed hopper 10. The side baffle strips 17 are clamped between the front plate 13 and the back plate 14, and the side baffle strips 17 extend out of the lower opening 12 of the preformed hopper 10 from the top of the side plate 15. The bottom of the side baffle strips 17 is located below the lower opening 12 of the preformed hopper 10, so as to prevent leakage of materials on both sides of the preformed hopper 10. When the powder 50 falls, its width can be restricted by the side baffle strips 17, so as to further ensure the profile into which the powder 50 falls.

[0067] The side baffle strips 17 can be made of rigid materials (such as metal plates, acrylic, etc.) or flexible materials or made by wrapping flexible materials at predetermined positions on the periphery of rigid materials.

[0068] Preferably, in an embodiment of the present invention, the side baffle strips 17 are made of a material with a rigid inner and flexible outer. The side baffle strips 17 are usually selected to be slightly larger. The side baffle strips 17 are installed inside the side plate 15 (i.e., the inner cavity of the preformed hopper 10). When the front plate 13 and the back plate 14 clamp the side plate 15, the flexible material on the periphery of the side baffle strips 17 is deformed by being clamped by the front plate 13 and the back plate 14, so that the side gaps are blocked, further ensuring that the powder 50 will not leak from both sides.

[0069] Specifically, a sponge, which is a material with low cost and easy to process, can be selected for the periphery of the side baffle strips 17. After the sponge is bonded, it is squeezed by the front plate 13 and the back plate 14, so as to realize the sealing of the side of the preformed hopper 10.

[0070] Furthermore, if the width of the fabric needs to be adjusted, it can be achieved by simply moving the position of the side baffle 17.

[0071] Furthermore, the preformed hopper 10 further includes a baffle 16, which is installed on the back plate 14. The baffle 16 is also provided at the lower part of the preformed hopper 10, and the baffle 16 extends downward out of the preformed hopper 10. The bottom surface of the baffle 16 abuts against the gate plate 232, and the baffle 16 is used to block the powder material 50 so that it can only move in one direction.

[0072] Combined with Figure 1 , the conveyor belt moves in the direction shown by the arrow. The setting of the baffle 16 can effectively prevent the powder material 50 from moving backward along the conveyor belt.

[0073] Furthermore, the baffle 16 is also preferably made of a thin plate, so as to avoid the setting of the baffle 16 affecting the normal falling of the powder material 50. The illustrated thickness is only for facilitating the observation of the setting position of the baffle 16 (the actual installation position can be anywhere inside, outside or at the bottom of the back plate 14).

[0074] Combined with Figure 8 , when the baffle 16 extends downward out of the preformed hopper 10, since the baffle 16 is only provided on the back plate 14, a part of the powder material 50 will leak out from the Figure 8 left side shown. When the powder material 50 reaches a critical state, that is, after the powder material 50 collapses by one or two centimeters, the powder material 50 stops collapsing due to the gravitational force of its own weight

[0075] around. During fabric laying, this collapsed part 60 does not enter the press, and the powder material 50 on the right side of the collapsed part 60 is the normal powder material 50, and this part of the powder material 50 enters the press for pressing.

[0076] Although the baffle 16 and the gate plate 232 are in abutment, there is still a certain gap between the baffle 16 and the gate plate 232. As Figure 9 shown, during the long-term left and right movement of the gate plate 232, more and more powder material 50 will accumulate on the gate plate 232 between the frame body 231 and the baffle 16. During the accumulation process of the powder material 50, it will form lumps by itself. When the lumped part 70 increases, the powder material of the lumped part 0 70 will fall onto the belt 30 in a lump, and at this time the lumped powder material will seriously affect the forming quality of the ceramic tile.

[0077] Figure 9 Only a schematic diagram of the powder material lumping is drawn in

[0078] Combined with Figure 6Furthermore, in one embodiment of the present invention, in order to prevent the powder 50 from agglomerating and falling onto the belt 30 in a lump to affect the quality of tile forming, a plurality of through holes 2321 are provided on the gate plate 232, and the plurality of through holes 2321 are provided along the extension direction of the cross bar 2311. When the powder 50 moves to the position as shown in FIG. Figure 9 When the back plate 14 is between the frame 231 as shown, the small amount of powder 50 will leak out from the through hole 2321 , and the small amount of dispersed powder 50 falling on the belt 30 will not affect the overall pressing effect of the powder 50 .

[0079] 0Combination Figure 3 and Figure 8 or Figure 9 The thickness of the lower part of the front plate 13 and the back plate 14 is gradually decreasing from top to bottom.

[0080] When the thickness of the bottom surface of the front plate 13 and the back plate 14 reaches the thinnest, the contact area between the powder 50 and the front plate 13 is small after the powder 50 falls, and the particle shape of the powder 50 will be maintained higher, that is, the pressing effect will be better.

[0081] At the same time, refer to Figure 4 After the powder 50 falls onto the belt 30, the powder 50 needs to be transferred from the belt 30 to other belts 30. In order to facilitate the complete transmission of the powder 50, a discharge plate 40 is provided on one side of the discharge port of the belt 30. One side of the discharge plate 40 is tightly attached to the belt 30 and the discharge surface of the discharge plate 40 is tangent to the belt 30. At this time, the powder 50 can be completely transferred from the belt 30.

[0082] Specifically, combined Figure 10 and Figure 11 When the material distribution device is working, the belt 30 moves in a direction away from the press 80, and the powder falls on the belt 30. After the powder has finished falling, the belt 30 carries the powder away from the preforming bucket 10. At this time, the preforming bucket 10 can rise or the belt 30 can fall to avoid the preforming bucket 10 interfering with the powder conveyed by the belt. Then the belt 30 drives the powder to move closer to the press 80, and the powder falls into the mold cavity of the press 80, and then the press 80 presses the powder. In the process of falling, the powder has a process of gradually adjusting the inclination direction of the texture, so that the texture direction of the powder eventually tends to be perpendicular to the bottom surface of the mold cavity of the press 80.

[0083] Define the conveying direction of the belt conveying powder closer to the press as forward rotation, and the conveying direction of the belt conveying powder away from the press as reverse rotation.

[0084] It should be noted that, combined with Figure 8 , when the belt 30 Figure 10-11When feeding, during the process of switching from reverse rotation to forward rotation, the preforming hopper 10 and the belt 30 move away from each other, or the preforming hopper 10 moves upward, or the belt 30 moves downward, that is, the preforming hopper 10 and the belt 30 move relatively away from each other to avoid interference with the powder by the switching unit during the forward rotation of the belt.

[0085] Similarly, when the belt 30 rotates in reverse (when the preforming hopper 10 discharges materials), the belt 30 and the preforming hopper 10 move closer to each other, or the belt 30 moves upward to approach the preforming hopper 10, or the preforming hopper 10 moves downward to approach the belt 30, so that the falling distance of the powder is shorter and the powder texture can be continuous.

[0086] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
