After injecting the sample powder into the sample test channel, the sample feeding test can be carried out on the brick body, with high working efficiency and no need to disassemble and assemble the tile feeding hopper.

Description

Technical Field

[0001] The present invention relates to the technical field of tile production, and particularly to a tile cloth hopper. Background Art

[0002] When existing tile cloth equipment produces wall and floor tiles with multiple colors and specific decorative patterns, usually two or more hoppers need to be equipped. By controlling the reciprocating movement of these hoppers filled with different powder materials, the cloth work of different colors and patterns of the entire brick body can be achieved.

[0003] Existing hoppers generally can only hold one color or type of powder material. Therefore, when manufacturing tile samples, it is often necessary to empty all the powder in the hopper for normal batch production and clean the inner wall of the hopper before adding the powder for manufacturing sample tiles to carry out sample manufacturing. Similarly, when normal tile production needs to be resumed, all the powder in the hopper also needs to be emptied and the inner wall of the hopper needs to be cleaned before adding the powder for the currently batch-produced tiles. It can be seen that not only multiple disassembly and assembly of the hopper are required, the process is cumbersome and time-consuming, but also the powder of the products in normal production is wasted.

[0004] Although the existing patent (CN 1868712A) can be adopted to provide a ceramic tile cloth composite hopper, by setting an auxiliary hopper in the main hopper, the auxiliary hopper and the main hopper do not affect each other, so that the composite hopper can hold two or more types of powder materials at the same time. However, the auxiliary hopper occupies a large amount of space in the main hopper, resulting in very little powder that can be stored in the main hopper, which easily affects the normal cloth efficiency. Moreover, the main hopper also needs to avoid the position where the auxiliary hopper is set for feeding, resulting in the complication of the feeding process. Summary of the Invention

[0005] In view of the above deficiencies of the existing technology, the purpose of the present invention is to provide a tile cloth hopper, aiming to form a sample test channel in the hopper during sample cloth, but not affecting the internal space of the hopper during normal cloth.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A kind of hopper for ceramic tile fabric, comprising a hopper main body with an upper cavity and a lower cavity, a movable partition arranged in the upper cavity and capable of moving horizontally, a first driving device for driving the movable partition to move, and a fixed partition vertically arranged at the middle position of the lower cavity. The hopper main body is hollow and has a main material inlet at its top. The fixed partition is used to form a first lower chamber and a second lower chamber inside the lower cavity. The movable partition can be connected to the fixed partition to form a first upper chamber and a second upper chamber inside the upper cavity. The bottom of the hopper main body is provided with a first discharge port and a second discharge port. The first discharge port is communicated with the first lower chamber and is controlled to open and close by a first valve. The second discharge port is communicated with the second lower chamber and is controlled to open and close by a second valve. A scraper for cleaning the inner wall of the second lower chamber is arranged in the second lower chamber, and the scraper is controlled to reciprocate by a second driving device.

[0008] As a further improvement of the above technical solution, the movable partition is an iron plate, and the first driving device comprises a first electromagnet and a second electromagnet arranged on the outer wall of the upper cavity. The first electromagnet is used to generate a magnetic attraction with the movable partition to drive the movable partition to move leftward and connect with the fixed partition. The second electromagnet is used to generate a magnetic attraction with the movable partition to drive the movable partition to move rightward and press against the inner wall of the hopper main body.

[0009] As a further improvement of the above technical solution, two tracks extending left and right are arranged on the inner wall of the hopper main body. Corresponding guiding sliding grooves are arranged on the movable partition and are slidably connected to the tracks through the guiding sliding grooves.

[0010] As a further improvement of the above technical solution, the cross-section of the track is an equilateral trapezoid, and the side where the short side is located is connected to the inner wall of the hopper main body. The cross-section of the guiding sliding groove is the same as that of the track. A limiting projection for limiting the moving stroke of the movable partition is arranged at one end of the track far from the second electromagnet.

[0011] As a further improvement of the above technical solution, the cross-section of the upper cavity is rectangular, and the cross-section of the lower cavity is semi-circular.

[0012] As a further improvement of the above technical solution, two transfer shafts are arranged on the scraper, and the transfer shafts extend out of the lower cavity. The second driving device comprises a servo motor arranged on the outer wall of the hopper main body, and the output shaft of the servo motor is in transmission connection with the transfer shaft.

[0013] As a further improvement of the above technical solution, a sample material inlet communicated with the second upper chamber is arranged on the side wall of the upper cavity.

[0014] As a further improvement of the above technical solution, a vibration motor is arranged on the outer wall of the upper cavity.

[0015] As a further improvement of the above technical solution, hooks are provided on the front side and the rear side of the lower cavity.

[0016] Beneficial effects:

[0017] Compared with the prior art, the tile feeding hopper provided by the present invention has two working modes. When in the normal feeding mode, the first driving device drives the movable partition to move to the right, so that the movable partition closely adheres to the right side plate of the upper cavity, and the powder for normal production fills the inner cavity of the entire hopper body, making full use of the internal space of the entire hopper body. After the first valve and the second valve open the first discharge port and the second discharge port, the powder is discharged from the first discharge port and the second discharge port to achieve feeding, ensuring the feeding efficiency and effect.

[0018] When changing from the normal batch feeding mode to the sample feeding mode, the first valve closes the first discharge port, the second valve opens the second discharge port, and first discharges part of the powder in the second lower chamber for pressure relief. Then the first driving device drives the movable partition to move to the left, so that the movable partition is connected with the fixed partition, and a first upper chamber and a second upper chamber are formed inside the upper cavity. The first upper chamber and the first lower chamber are communicated to form a buffer channel, and the second upper chamber and the second lower chamber are communicated to form a sample test channel; part of the powder for normal feeding is temporarily stored in the buffer channel and waits for subsequent normal batch feeding, reducing the waste of powder; before injecting the sample powder into the sample test channel, it is necessary to empty the powder for normal feeding in the sample test channel. The second driving device drives the scraper to swing reciprocally to scrape the powder on the inner wall of the second lower chamber, so as to prevent the sample powder and the powder for normal feeding from being mixed with each other; after injecting the sample powder into the sample test channel, a sample feeding test can be carried out on the brick body, with high working efficiency and no need to disassemble and assemble the tile feeding hopper.

Detailed implementation

[0025] The present invention provides a tile feeding hopper. To make the purpose, technical solution and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention.

[0026] Please refer to Figures 1 to 5 The present invention provides a tile feeding hopper, which includes a hopper body 1 having an upper cavity 11 and a lower cavity 12, a movable partition 2 disposed in the upper cavity 11 and capable of moving horizontally, a first driving device for driving the movable partition 2 to move, and a fixed partition 4 vertically disposed at the middle position of the lower cavity 12. The hopper body 1 is hollowly arranged and has a main material inlet 81 opened at its top. The fixed partition 4 is used to form a first lower chamber 41 and a second lower chamber 42 inside the lower cavity 12. The movable partition 2 can be connected with the fixed partition 4 to form a first upper chamber 21 and a second upper chamber 22 inside the upper cavity 11. The bottom of the hopper body 1 is provided with a first discharge port 13 and a second discharge port 14. The first discharge port 13 is communicated with the first lower chamber 41 and is controlled to open and close by a first valve 51. The second discharge port 14 is communicated with the second lower chamber 42 and is controlled to open and close by a second valve 52. A scraper 61 for cleaning the inner wall of the second lower chamber 42 is disposed in the second lower chamber 42, and the scraper 61 is controlled to reciprocate by a second driving device 62.

[0027] In practical applications, the tile feeding hopper provided by the present invention has two working modes. When in the normal feeding mode, the first driving device drives the movable partition 2 to move to the right, so that the movable partition 2 closely adheres to the right side plate of the upper cavity 11. The powder for normal production fills the entire inner cavity of the hopper body 1, making full use of the internal space of the entire hopper body 1. After the first valve 51 and the second valve 52 open the first discharge port 13 and the second discharge port 14, the powder is discharged from the first discharge port 13 and the second discharge port 14 to achieve feeding, ensuring the feeding efficiency and effect.

[0028] When changing from the normal fabric mode to the sample fabric mode, the first valve 51 closes the first discharge port 13, and the second valve 52 opens the second discharge port 14. First, part of the powder in the second lower chamber 42 is discharged for pressure relief. Then, the first driving device drives the movable partition 2 to move leftward, so that the movable partition 2 is connected to the fixed partition 4. A first upper chamber 21 and a second upper chamber 22 are formed inside the upper cavity 11. The first upper chamber 21 is communicated with the first lower chamber 41 to form a buffer channel, and the second upper chamber 22 is communicated with the second lower chamber 42 to form a sample test channel B. Part of the powder for normal fabric is temporarily stored in the buffer channel A and waits to continue normal batch fabric in the future, reducing the waste of powder. Before injecting the sample powder into the sample test channel B, it is necessary to empty the powder for normal fabric in the sample test channel B. The second driving device 62 drives the scraper 61 to swing reciprocally to scrape the powder on the inner wall of the second lower chamber 42, so as to prevent the sample powder and the powder for normal fabric from being mixed with each other. After injecting the sample powder into the sample test channel, the sample fabric test can be carried out on the brick body, with high working efficiency and no need to disassemble and assemble the tile fabric hopper.

[0029] When changing from the sample fabric mode to the normal fabric mode, the sample powder in the sample test channel B is emptied, and the second driving device 62 is used to drive the scraper 61 to swing reciprocally to scrape the powder on the inner wall of the second lower chamber 42. The first driving device drives the movable partition 2 to move rightward to reset, and the movable partition 2 closely adheres to the right side plate of the upper cavity 11, thereby eliminating the setting of the sample test channel B. The powder located in the buffer channel will pour into the second upper chamber 22 and the second lower chamber 42, and normal fabric production work can be immediately carried out.

[0030] In this embodiment, the movable partition 2 is an iron plate, and the first driving device includes a first electromagnet 31 and a second electromagnet 32 arranged on the outer wall of the upper cavity 11. When performing normal batch fabric, the second electromagnet 32 is turned on, the first electromagnet 31 is turned off, and the second electromagnet 32 has a magnetic attraction effect on the movable partition 2, driving the movable partition 2 to move rightward and closely adhere to the inner wall of the hopper main body 1, so as to make full use of the inner cavity of the entire hopper main body 1. When fabricating a sample, the first electromagnet 31 is turned on, the second electromagnet 32 is turned off, and the first electromagnet 31 has a magnetic attraction effect on the movable partition 2, driving the movable partition 2 to move leftward and connect with the fixed partition 4.

[0031] Two left - right extending tracks 7 are arranged on the inner wall of the hopper main body 1. Corresponding guiding chutes are arranged on the movable partition 2 and the movable partition 2 is slidably connected to the tracks 7 through the guiding chutes. On the one hand, the tracks 7 support the movable partition 2 to ensure that the movable partition 2 is in a vertical state. On the other hand, the tracks 7 ensure that the moving direction of the movable partition 2 is accurate and the movement is stable.

[0032] In this embodiment, the cross-section of the track 7 is an equilateral trapezoid, and the side where the short side is located is connected to the inner wall of the hopper main body 1. The cross-section of the guiding chute is the same as that of the track 7, which can prevent the movable partition 2 from derailing.

[0033] Preferably, a limiting protrusion for restricting the moving stroke of the movable partition 2 is provided at one end of the track 7 away from the second electromagnet 32. When the movable partition 2 abuts against the limiting protrusion, the movable partition 2 moves to the middle position of the upper cavity 11, and the bottom surface of the movable partition 2 is connected to the top surface of the fixed partition 4.

[0034] Preferably, the cross-section of the upper cavity 11 is rectangular, and the cross-section of the lower cavity 12 is semi-circular. By setting like this, on the one hand, it is convenient to arrange components inside the hopper main body 1, and on the other hand, it can prevent powder from hiding in the corners and better clean the inner cavity of the hopper main body 1.

[0035] Further, two transfer shafts are provided on the scraping plate 61, and the transfer shafts extend out of the lower cavity 12. The second driving device 62 includes a servo motor provided on the outer wall of the hopper main body 1, and the output shaft of the servo motor is in transmission connection with the transfer shaft. The servo motor is used to drive the scraping plate 61 to reciprocally scrape the inner wall of the lower cavity 12 in the second lower chamber 42, ensuring that when the powder in the sample test channel B is emptied, the powder remaining on the inner wall of the lower cavity 12 is reduced, and the sample powder and the powder for normal cloth feeding do not mix with each other.

[0036] Preferably, a sample material feeding port 82 communicating with the second upper chamber 22 is provided on the side wall of the upper cavity 11. By setting like this, there is no need to modify the structure of the feeding device for normal mass production. When a sample needs to be manufactured, the sample powder is fed into the sample test channel from the sample material feeding port 82, which is simple and fast. During normal mass cloth feeding, the sample material feeding port 82 is closed, and the powder for normal cloth feeding is injected from the main material feeding port 81. The setting is simple and there is no need to modify the feeding device.

[0037] Preferably, a vibration motor 91 is provided on the outer wall of the upper cavity 11. The high-frequency vibration generated by the vibration motor 91 is transmitted to the hopper main body 1, which can cause the powder attached to the inner wall of the hopper main body 1 to shake off, playing a better cleaning role. Preferably, the vibration motor 91 is arranged at a position close to the track 7. The vibration motor 91 emits high-frequency vibration, so that the powder attached to the track 7 can be better vibrated and shaken off, playing a cleaning role for the track 7.

[0038] Preferably, hooks 92 are provided on the front side and the rear side of the lower cavity 12. The powder recovery bag is hung on the hooks 92, which is convenient to use. When the powder in the sample test channel needs to be emptied, the second valve 52 controls the second discharge port 14 to open, and the powder in the sample test channel B is discharged from the second discharge port 14, and the powder recovery bag receives the powder. Similarly, when the powder in the entire hopper body 1 needs to be emptied, the first discharge port 13 and the second discharge port 14 are opened, and the first valve 51 and the second valve 52 control the first discharge port 13 and the second discharge port 14 to open. The powder in the hopper body 1 is discharged from the first discharge port 13 and the second discharge port 14, and the powder recovery bag receives the powder.
