Description

Technical Field

[0001] The invention relates to the technical field of brick blank manufacturing equipment, in particular to a distribution machine for producing full-body brick blanks. Background Art

[0002] At present, with the progress of society and the continuous improvement of people's living standards, people's decoration of porcelain tiles is no longer limited to the beauty brought by the surface decoration of the product. During the paving and decoration process of ceramic tiles, the internal color of the tiles will be exposed due to surface grooving, cutting or chamfering, making the color and pattern inside and outside inconsistent, thus greatly reducing the overall decoration grade and beauty. Therefore, the consistency of the internal and surface colors and corresponding texture effects of the product, that is, the similarity between the connotation of the tile and the surface decoration (the inside and outside of the tile are the same) is an important research content for building ceramics companies.

[0003] The distribution machine used in the manufacture of brick blanks is used to selectively drop the powder according to the texture of the required brick blanks, so as to form a powder layer with a unique texture. In the existing distribution machine, the distribution mechanism usually distributes the powder on the first transmission mechanism, and then the powder is discharged from the first transmission mechanism to the second transmission mechanism. In this process, due to the movement of the first transmission mechanism, the powder has a certain initial speed after leaving the second transmission mechanism, so that the path of the powder discharged from the first transmission mechanism to the second transmission mechanism is a parabola; this easily causes the pattern and texture formed by the powder falling on the second transmission mechanism to deviate from the actual requirements, and finally causes the color and corresponding texture effect of the interior and surface of the brick blank to be inconsistent. Summary of the invention

[0004] The purpose of the present invention is to provide a material distribution machine for producing full-body brick blanks, aiming to solve the technical problem in the prior art that the internal and surface colors and corresponding texture effects of the brick blanks are not consistent.

[0005] To achieve the above object, the present invention provides a material distribution machine for producing full-body brick blanks, comprising:

[0006] frame;

[0007] A first transmission mechanism, which is arranged on the frame;

[0008] a second transmission mechanism, which is disposed on the frame and located directly above the first transmission mechanism;

[0010] The material distributing mechanism is arranged on the frame and is located directly above the second transmission mechanism.

[0011] The powder is blocked by the unloading baffle to eliminate the initial speed of the powder after it leaves the second transmission mechanism, so that the powder can fall vertically on the first transmission mechanism, thereby making the pattern and texture formed by the powder more accurate, ensuring the consistency of the color and corresponding texture effect between the inside and surface of the brick.

[0013] Preferably, the unloading baffle plate includes a vertical plate and an inclined plate, wherein the inclined plate is arranged at the lower end of the vertical plate and is inclined from top to bottom toward the side where the second transmission mechanism is located. The inclined plate can guide the powder material to a certain extent when the powder material is blocked by the vertical plate and falls downward, so that the pattern and texture formed by the powder material are more accurate, and the whole body effect of the whole body brick is better.

[0014] Preferably, the included angle formed between the vertical plate and the inclined plate is α, 120°≤α≤150°. When the included angle α is within the range of 120° to 150°, the guiding effect can be ensured, thereby ensuring the accuracy of powder distribution.

[0015] Preferably, the unloading baffle is provided with an anti-sticking layer on one side close to the second transmission mechanism, so as to prevent the powder from sticking to the unloading baffle and affecting the distribution accuracy.

[0016] Preferably, a plurality of the material distribution mechanisms are sequentially arranged directly above the second transmission mechanism. Arranging a plurality of material distribution mechanisms can meet the demand for producing bricks with unique textures.

[0017] Preferably, the material distribution mechanism includes a feeding pipe, a feeding funnel and a feeding nozzle, the feeding pipe is arranged directly above the feeding funnel, and a plurality of feeding nozzles are arranged at the feeding port of the feeding funnel. The plurality of nozzles can make the texture of the brick more precise and the color accuracy higher.

[0018] Preferably, the length of the distribution funnel is L2, the width of the transmission part of the second transmission mechanism is W, and L2 ≥ W. The width of the powder layer can be increased as much as possible, thereby increasing the width of the bricks, making the production efficiency of the bricks higher.

[0019] Preferably, it also includes a moving device, which is used to drive the feeding pipe to move back and forth along the length direction of the distribution funnel, so that the powder is more uniform in the distribution funnel.

[0020] Preferably, the distance D between two adjacent material distribution nozzles is less than 1.5 mm; this can make the material distribution more precise and the texture of the bricks more refined.

[0033] like Figures 1 to 5 As shown, a material distribution machine for producing full-body brick blanks comprises:

[0034] Rack 1;

[0035] A first transmission mechanism 2, which is arranged on the frame 1;

[0036] a second transmission mechanism 3, which is arranged on the frame 1 and is located directly above the first transmission mechanism 2;

[0037] A material discharge baffle 4 is installed on the frame 1, the material discharge baffle 4 is located at the front end of the material discharge end of the second conveying mechanism 3, and a gap is left between the second conveying mechanism 3 and the material discharge baffle 4, and the material discharge baffle 4 is used to block the powder material discharged from the second conveying mechanism 3 to the first conveying mechanism 2, so that the powder material can fall vertically onto the first conveying mechanism 2;

[0038] The material distribution mechanism 5 is arranged on the frame 1 and is located directly above the second transmission mechanism 3 .

[0039] The frame 1 is the base of the entire material distribution machine, and is used to carry the first transmission mechanism 2, the second transmission mechanism 3, the material discharging baffle 4 and the material distribution mechanism 5 and other parts of the material distribution machine; the first transmission mechanism 2, the second transmission mechanism 3, the material discharging baffle 4 and the material distribution mechanism 5 are specifically connected to the frame bar 11 of the frame 1 and then fixed on the frame 1. The first transmission mechanism 2 is arranged on the frame 1, and the first transmission mechanism 2 can adopt the belt transmission method. It is arranged on the frame 1 and can operate normally to transmit the powder carried on the belt. The second transmission mechanism 3 can also adopt the belt transmission method. It is arranged on the frame 1 and can operate normally to transmit the powder carried on the belt. The second transmission mechanism 3 is located directly above the first transmission mechanism 2, and the first transmission mechanism 2 can receive the powder discharged from the second transmission mechanism 3. A material discharge baffle 4 is also installed on the frame 1, and the material discharge baffle 4 is located at the front end of the material discharge end of the second conveying mechanism 3. There is a certain gap between the material discharge baffle 4 and the second conveying mechanism 3 for the powder to pass through; when the powder is discharged from the second conveying mechanism 3, due to the movement of the second conveying mechanism 3, the powder has a certain initial speed after leaving the second conveying mechanism 3, and then the powder falls onto the first conveying mechanism 2; and a baffle is set at the front end of the discharge end of the second conveying mechanism 3 to block the powder separated from the second conveying mechanism 3. The baffle eliminates the initial speed of the powder, so that the powder can only fall into the first conveying mechanism 2 under the action of gravity. The material distribution mechanism 5 is set on the frame 1 and is located directly above the second conveying mechanism 3. The material distribution mechanism 5 is used to place the powder on the second conveying mechanism 3 according to the pattern requirements.

[0040] In an existing distribution machine, a distribution mechanism usually distributes powder on a first conveying mechanism, and then the powder is discharged from the first conveying mechanism to a second conveying mechanism. During this process, due to the movement of the first conveying mechanism, the powder has a certain initial speed after leaving the second conveying mechanism, so that the path of the powder discharged from the first conveying mechanism to the second conveying mechanism is a parabola; this easily causes the pattern and texture formed by the powder distributed on the second conveying mechanism to deviate from the actual requirements to a certain extent. In the present technical solution, a discharge baffle 4 is arranged at the front end of the discharge end of the second conveying mechanism 3. The discharge baffle 4 blocks the powder to eliminate the initial speed of the powder after it leaves the second conveying mechanism 3, so that the powder can fall vertically on the first conveying mechanism 2, thereby making the pattern and texture formed by the powder more precise, ensuring the consistency of the color inside and surface of the brick blank and the corresponding texture effect; the graphics of the prepared ceramic tiles are decomposed according to the different colors, and the precise and quantitative distribution of blank powders of different colors is achieved through multiple distribution methods, so that the whole body brick has the whole body effect of material (both the blank and the surface are porcelain), color (the color of the blank and the surface are similar), and texture (the texture of the blank and the surface are consistent).

[0041] Furthermore, the length of the unloading baffle 4 is L1, the width of the transmission part of the second transmission mechanism 3 is W, and L1≥W.

[0042] The second transmission mechanism 3 is installed on the frame 1, and its transportation direction is from one end of the frame 1 to the other end of the frame 1; the transmission part of the second transmission mechanism 3 refers to the part that carries and transports the sealed material (if the second transmission mechanism 3 is a belt transmission, the transmission part of the second transmission mechanism 3 is a belt), and the width direction of the transmission part of the second transmission mechanism 3 is perpendicular to its transportation direction. The length direction of the material removal baffle 4 is perpendicular to the transportation direction of the second transmission mechanism 3, that is, the material removal baffle 4 is mounted on both sides of the frame 1, so the width direction of the second transmission mechanism 3 is parallel to the length direction of the material removal baffle 4. When the feeding mechanism 5 is feeding on the second conveying mechanism 3, under the condition of meeting the production requirements, it will generally feed wider powder as much as possible, that is, feed more material in the width direction of the second conveying mechanism 3 as much as possible; therefore, the length L1 of the unloading baffle 4 is ≥ the width W of the conveying part of the second conveying mechanism 3. Even if the second conveying mechanism 3 feeds more powder in its width, it can still be ensured that the unloading baffle 4 can block the powder on the second conveying mechanism 3 to eliminate the initial speed of the powder after it leaves the second conveying mechanism 3, thereby making the pattern and texture formed by the powder more precise and the whole body effect of the whole body tile better.

[0043] Furthermore, the unloading baffle plate 4 includes a vertical plate 41 and an inclined plate 42 . The inclined plate 42 is disposed at the lower end of the vertical plate 41 , and the inclined plate 42 is inclined from top to bottom toward the side where the second transmission mechanism 3 is located.

[0044] The material discharge baffle 4 is formed of a vertical plate 41 and an inclined plate 42, the vertical plate 41 is parallel to the bearing plane of the first transmission mechanism 2, and the inclined plate 42 is arranged at the lower end of the vertical plate 41 and is inclined from top to bottom toward the side where the second transmission mechanism 3 is located, that is, the lower end of the inclined plate 42 is closer to the second transmission mechanism 3 than the upper end thereof. After the vertical plate 41 blocks the powder, the powder will more or less generate an opposite force, so that the powder may be a little scattered during the falling process, affecting the distribution accuracy; in this embodiment, the material discharge baffle 4 is set to be a structure composed of the vertical plate 41 and the inclined plate 42, so that when the powder is blocked by the vertical plate 41 and falls downward, the inclined plate 42 can play a certain guiding role on the powder, so that the pattern and texture formed by the powder are more accurate, and the whole body effect of the whole body brick is better.

[0045] Furthermore, the included angle formed between the vertical plate 41 and the inclined plate 42 is α, and 120°≤α≤150°.

[0046] There is a certain angle between the vertical plate 41 and the inclined plate 42, and the range of the angle is 120° to 150°; if the angle α is less than 120°, it is easy to affect the falling speed of the powder, and if the angle α is greater than 150°, it is difficult to play a guiding role; therefore, when the angle α is within the range of 120° to 150°, the guiding effect can be guaranteed, thereby ensuring the accuracy of the powder distribution.

[0047] Furthermore, the unloading baffle plate 4 is provided with an anti-sticking layer 43 on one side close to the second transmission mechanism 3. The anti-sticking layer 43 is used to prevent the powder from sticking to the unloading baffle plate 4, thereby affecting the cloth accuracy; the anti-sticking layer 43 can be made of polyurethane material or silicone rubber material.

[0048] Furthermore, a plurality of the material distribution mechanisms 5 are sequentially arranged directly above the second transmission mechanism 3 .

[0049] The texture of the brick blank is specifically formed by arranging powders of different colors according to certain rules. Therefore, in the process of producing brick blanks, it is usually necessary to spread powders of multiple colors together to form a single layer of powder, and then stack multiple layers of powder to form a blank. A plurality of spreading mechanisms 5 are arranged in sequence directly above the second transmission mechanism 3. Each spreading mechanism 5 is responsible for spreading powders of a corresponding color. Different numbers of spreading mechanisms 5 are set according to the number of colors of the full-body brick blanks to be produced. The transmission part of the second transmission mechanism 3 passes through a plurality of spreading mechanisms 5 in sequence. The plurality of spreading mechanisms 5 spreads powders of corresponding colors on the second transmission mechanism 3 to form a powder layer with a unique texture. Setting a plurality of spreading mechanisms 5 can meet the demand for producing brick blanks with unique textures.

[0050] Furthermore, the material distribution mechanism 5 includes a material discharge pipe 51 , a material distribution funnel 52 and a material distribution nozzle 53 . The material discharge pipe 51 is arranged directly above the material distribution funnel 52 , and a plurality of material distribution nozzles 53 are arranged at the discharge port of the material distribution funnel 52 .

[0051] The distribution funnel 52 is a structure with openings at both the upper and lower ends. The upper opening is used to allow powder to enter the funnel, and the lower opening is used to discharge the powder onto the second transmission mechanism 3. The feeding pipe 51 is arranged directly above the distribution funnel 52, and is used to discharge the powder into the distribution funnel 52. A distribution nozzle 53 is installed on the feeding port of the distribution funnel 52, and the powder in the distribution funnel 52 is distributed on the second transmission mechanism 3 through the distribution nozzle 53. A plurality of distribution nozzles 53 are installed on the distribution funnel 52, and the plurality of distribution nozzles 53 are evenly spaced along the length direction of the distribution mechanism 5. The width direction of the second transmission mechanism 3 is divided into hundreds or thousands of cells, and the area of ​​each cell is generally less than or equal to 4mm×4mm. Therefore, each distribution nozzle 53 corresponds to a cell, that is, the powder discharged by each distribution nozzle 53 will fall on the corresponding cell. Setting multiple nozzles can make the texture of the brick more precise and the color accuracy higher.

[0052] Furthermore, the length of the material distribution funnel 52 is L2, the width of the transmission part of the second transmission mechanism 3 is W, and L2≥W.

[0053] The length direction of the distribution funnel 52 is consistent with the width direction of the transmission part of the second transmission mechanism 3. The length L2 of the distribution funnel 52 determines the width of the powder layer formed by the powder distribution on the second transmission mechanism 3. The length L2 of the distribution funnel 52 is designed to be ≥ the width W of the transmission part of the second transmission mechanism 3. The width of the powder layer can be increased as much as possible, thereby increasing the width of the brick blank, making the production efficiency of the brick blank higher.

[0054] Furthermore, it also includes a moving device 6, and the moving device 6 is used to drive the feeding pipe 51 to move back and forth along the length direction of the feeding funnel 52.

[0055] The distribution funnel 52 is in the shape of a long strip, which is mounted on the frame 1 and is located directly above the second conveying mechanism 3; the feeding pipe 51 is used to discharge the powder into the distribution funnel 52. Since the distribution funnel 52 is relatively long, in order to make the powder more uniform in the distribution funnel 52, the present embodiment is provided with a moving device 6, which drives the feeding pipe 51 to move back and forth in the length direction of the distribution funnel 52 to evenly distribute the powder in the distribution funnel 52, thereby ensuring that each distribution nozzle 53 can accurately discharge the cloth onto the second conveying mechanism 3 when needed. The moving device 6 can adopt a transmission form in which a motor, a screw rod and a nut seat are coordinated. For example, the screw rod is connected to the output end of the motor, the nut seat is set on the screw rod, and the feed tube 51 is connected to the nut seat; the motor drives the screw rod to rotate, and the rotation of the screw rod drives the nut seat to slide on the screw rod, and the threaded seat drives the feed tube 51 to move; of course, the moving device 6 can also be other transmission forms, such as a motor driving a gear rack transmission or a cylinder driving the telescopic rod to extend and retract, etc.

[0056] Furthermore, the distance D between two adjacent material dispensing nozzles 53 is less than 1.5 mm.

[0057] As mentioned above, each material distribution nozzle 53 corresponds to a cell on the second transmission mechanism 3, so it is necessary to ensure that the gap D between each material distribution nozzle 53 is not too large, otherwise it is difficult to achieve the accuracy requirement of material distribution. The spacing D between two adjacent material distribution nozzles 53 is less than 1.5mm, which can make the material distribution more accurate and the texture of the brick more refined.

[0058] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
