Description

Technical Field

[0001] This invention relates to the field of ceramic production equipment technology, and in particular to a dry granule fabric production line. Background Technology

[0002] In ceramic tile production, the adhesive-positioned dry granule process involves spraying adhesive followed by the application of dry granules to create decorative textures. Existing dry granule application production lines typically employ a full-surface application method, where the application device evenly distributes powder across the entire tile surface, while the adhesive spraying mechanism only applies adhesive to specific patterned areas. This results in a large amount of dry granules falling into non-adhesive areas and failing to adhere, leading to significant waste. Furthermore, full-surface application necessitates the subsequent dry granule removal mechanism to remove substantial amounts of excess powder, resulting in a high removal load, high energy consumption, and easy contamination of the powder during removal, making recycling difficult. Additionally, existing application mechanisms cannot selectively apply powder to specific areas based on the sprayed pattern, leading to poor powder distribution precision on the tile and negatively impacting the decorative effect.

Detailed Implementation

[0016] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] The following is combined with Figures 1 to 5 Embodiments of the present invention will be described.

[0018] In existing dry granule fabric production lines, traditional fabric spreading devices typically use a full-surface spreading method, that is, spreading dry granules over a large area on the entire surface of the brick blank. However, the glue spraying mechanism 3 only sprays glue on specific patterned areas on the surface of the brick blank, causing a large number of dry granules to fall into non-glue areas and fail to adhere. Subsequently, a large amount of these excess dry granules need to be removed by a suction device, which not only causes serious waste of dry granules but also increases the load and energy consumption of the suction device.

[0019] This invention provides a dry granule fabric production line, comprising a frame 1, a conveyor belt 2, a glue spraying mechanism 3, a dry granule fabric dispensing mechanism 4, a dry granule suction mechanism 5, and a dry granule feeding device 6. The conveyor belt 2 is mounted on the frame 1. The glue spraying mechanism 3, the dry granule fabric dispensing mechanism 4, and the dry granule suction mechanism 5 are all mounted on the frame 1 and arranged sequentially along the conveyor belt 2. The glue spraying mechanism 3 is used to spray glue onto the brick blank for powder adhesion. The dry granule fabric dispensing mechanism 4 is used to output powder onto the brick blank for adhesion. The dry granule suction mechanism 5 is used to remove excess powder that has not been adhered. The dry granule feeding device 6 is used to supply powder to the dry granule fabric dispensing mechanism 4. The dry granule fabric dispensing mechanism 4 includes multiple sets of movable feeding components that can be partially opened or closed. With this configuration, the glue spraying mechanism 3, the dry granule spreading mechanism 4, and the dry granule suction mechanism 5 are arranged sequentially in the conveying direction of the conveyor belt 2, so that the brick blank can sequentially complete the processes of glue spraying, spreading, and suction of excess powder during the conveying process. Furthermore, the dry granule spreading mechanism 4, through its multiple sets of movable feeding components that can be partially opened or closed, can open only the movable feeding components corresponding to the glue spraying pattern according to the specific distribution position of the glue spraying pattern on the surface of the brick blank, so that the powder only falls into the glue spraying area, thereby improving the powder spreading accuracy and powder utilization rate on the brick blank.

[0020] Specifically, the conveyor belt 2 is mounted on the frame 1 and extends horizontally. The brick blank is placed on the upper surface of the conveyor belt 2, which runs along its conveying direction under the drive of an external drive source. The adhesive spraying mechanism 3 is located above the conveyor belt 2 and includes multiple adhesive spray nozzles spaced apart along the transverse direction of the conveyor belt 2. Each nozzle faces downwards toward the upper surface of the conveyor belt 2 and is used to spray adhesive onto specific patterned areas on the upper surface of the brick blank as it passes. In existing dry granule feeding mechanisms 4, the width of the discharge port 421 is usually fixed and can only achieve full-surface discharge. When the adhesive spraying pattern on the brick blank surface is discontinuous, the powder will still fall in a full-surface manner, resulting in a large amount of powder falling into non-adhesive areas and wasting powder. To address this issue, the dry granule feeding mechanism 4 in this embodiment includes a hopper 41, a discharge bin 42, a first baffle plate 43, and a movable feeding assembly. The hopper 41 has a bin opening 411 at its lower part. Powder is fed into the hopper 41 from the upper opening and discharged downwards through the bin opening 411. The discharge bin 42 is fixedly connected to the hopper 41 and is located below the bin opening 411. The discharge bin 42 includes a lower discharge port 421. The first baffle plate 43 is fixedly connected to the discharge bin 42. A baffle plate 43 is located on one side of the discharge port 421. The movable feeding assembly includes a mounting base 45, a horizontal adjustment structure, a driver 47, and a movable stop bar 48. The mounting base 45 is mounted on the discharge hopper 42 via the horizontal adjustment structure. The driver 47 is mounted on the mounting base 45 and is drivenly connected to the movable stop bar 48 to open and close the discharge port 421 together with the first baffle plate 43. The horizontal adjustment structure allows the mounting base 45 to move laterally relative to the discharge hopper 42 and be locked in different positions. The driver 47 is a cylinder, the cylinder body of which is fixed to the mounting base 45. The piston rod of the cylinder is fixedly connected to the movable stop bar 48, and the extension and retraction of the piston rod drives the movable stop bar 48 to move. In the dry granule feeding mechanism 4, multiple sets of movable feeding assemblies are arranged side by side in the transverse direction. Each set of movable feeding assemblies has its own mounting base 45, horizontal adjustment structure, driver 47, and movable stop bar 48. The sets are arranged adjacent to each other in the transverse direction, together covering the entire width range of the brick blank. During operation, the external control system determines the transverse position area to be fed based on the glue spraying pattern data of the glue spraying mechanism 3. Then, it controls the drivers 47 of each set of movable feeding assemblies respectively, so that the driver 47 of the movable feeding assembly located at the position corresponding to the glue spraying pattern drives the movable stop bar 48 to move to the discharge position, while the driver 47 of the movable feeding assembly located in the non-glue spraying area drives the movable stop bar 48 to remain in the stop position, thereby achieving the effect of feeding only locally to the glue spraying pattern area.When it is necessary to adjust the lateral discharge width of a certain set of movable feeding components, firstly, the locking of the set of lateral adjustment structures is released. Then, the set of mounting bases 45 is pushed laterally relative to the discharge bin 42 to a suitable position. The mounting bases 45 are then locked in this position by the lateral adjustment structure. The set of movable baffles 48 moves together with the mounting bases 45, thereby changing the relative positional relationship between the set of movable baffles 48 and the first baffle plate 43 in the lateral direction. This allows for adjustment of the discharge width to accommodate the material distribution requirements of different sized brick blanks or different pattern widths, thus improving the flexibility of adjusting the lateral discharge width of the discharge port 421. In this embodiment, the lateral adjustment structure adjusts the position of the movable baffles in a downward inclined direction, which has less impact on the powder falling space compared to rotational adjustment.

[0021] Furthermore, in this embodiment, to achieve lateral adjustment and locking of the mounting base 45 relative to the discharge bin 42, the lateral adjustment structure includes an adjusting base 46, a first oblong through hole 461, a second oblong through hole 462, a first screw hole 451, a first adjusting screw, a second adjusting screw, and a second screw hole 452. The adjusting base 46 is fixed on the discharge bin 42. The first oblong through hole 461 and the second oblong through hole 462 are both provided on the adjusting base 46, and the first screw hole 451 and the second screw hole 452 are both provided on the mounting base 45. The first adjusting screw passes through the first oblong through hole 461 and is threadedly connected to the first screw hole 451, and the second adjusting screw passes through the second oblong through hole 462 and is threadedly connected to the second screw hole 452. The first oblong through hole 461 and the second oblong through hole 462 are both elongated oval holes extending in the lateral direction, and the length direction of each oblong through hole is the lateral direction. When adjustment is required, the operator loosens the first and second adjusting screws respectively, allowing the first adjusting screw to have lateral movement space within the first oblong through hole 461 and the second adjusting screw to have lateral movement space within the second oblong through hole 462. Then, the mounting base 45 is pushed laterally to the desired position, and the first and second adjusting screws are tightened respectively, locking the mounting base 45 onto the adjusting seat 46 through the engagement of the first adjusting screw with the first oblong through hole 461 and the second adjusting screw with the second oblong through hole 462. The engagement of the two oblong through holes and the two adjusting screws provides two constraints to the mounting base 45 during lateral adjustment, thereby improving the ease of operation and positional stability of the lateral adjustment structure after locking.

[0022] Furthermore, to ensure that the height of the discharge port 421 relative to the conveyor belt 2 can accommodate brick blanks of different thicknesses, in this embodiment, the adjusting seat 46 is installed on the discharge bin 42 via a height adjustment structure. This height adjustment structure allows the installation height of the adjusting seat 46 on the discharge bin 42 to be adjustable. Specifically, the height adjustment structure includes a third oblong through hole 463, a fourth oblong through hole 464, a third height adjustment screw hole 423, a fourth height adjustment screw hole 424, a third height adjustment screw, and a fourth height adjustment screw. The third oblong through hole 463 and the fourth oblong through hole 464 are both located on the adjusting seat 46, and the third height adjustment screw hole 423 and the fourth height adjustment screw hole 424 are both located on the discharge bin 42. The third height adjustment screw passes through the third oblong through hole 463 and is threadedly connected to the third height adjustment screw hole 423, and the fourth height adjustment screw passes through the fourth oblong through hole 464 and is threadedly connected to the fourth height adjustment screw hole 424. Both the third oblong through-hole 463 and the fourth oblong through-hole 464 are elongated oval holes extending vertically, with the length direction of each oblong through-hole being vertical. When height adjustment is required, the operator loosens the third and fourth height adjustment screws respectively, allowing the third height adjustment screw to have vertical movement space within the third oblong through-hole 463 and the fourth height adjustment screw to have vertical movement space within the fourth oblong through-hole 464. Then, the operator moves the adjusting seat 46 vertically to the desired height position and tightens the third and fourth height adjustment screws respectively, locking the adjusting seat 46 at the corresponding height position on the discharge hopper 42. Since the mounting base 45 is mounted on the adjusting base 46 via the horizontal adjustment structure, and the discharge bin 42 is fixed to the hopper 41, when the height of the adjusting base 46 changes, the height of the mounting base 45 mounted on the adjusting base 46, as well as the driver 47 and the movable stop bar 48 on it, all change accordingly. This adjusts the distance between the lower edge of the discharge port 421 and the upper surface of the conveyor belt 2 to accommodate the gap requirements when brick blanks of different thicknesses pass through, thereby improving the height adaptability of the discharge port 421 relative to the conveyor belt 2.

[0023] In existing technologies, powder leakage often occurs when the discharge port 421 is closed because the movable baffle 48 and the baffle plate cannot form an effective sealing fit when closed. To address this issue, in this embodiment, the first baffle plate 43 is provided with an alignment groove 431 below the discharge port 421. The movable baffle 48 is driven by the driver 47 to move between the baffle position and the discharge position. When the movable baffle 48 moves to the baffle position, it abuts against the bottom surface of the alignment groove 431, sealing the discharge port 421. When the driver 47 drives the movable baffle 48 to move towards the first baffle plate 43 to the baffle position, the end of the movable baffle 48 away from the driver 47 extends into the alignment groove 431 and abuts against the bottom surface of the alignment groove 431. At this time, the movable baffle 48 and the first baffle plate 43 together completely seal the discharge port 421, preventing powder from falling from the discharge port 421. The abutting engagement between the movable baffle 48 and the bottom surface of the alignment groove 431 allows the movable baffle 48 to form a stable closed fit with the alignment groove 431 when in the material-blocking position, thereby improving the sealing effect of the discharge port 421 in the closed state. When the driver 47 drives the movable baffle 48 away from the first baffle plate 43 to the discharge position, the movable baffle 48 retracts from the alignment groove 431, forming a gap between the movable baffle 48 and the first baffle plate 43 for the powder to fall through, and the powder is output from the discharge port 421 through this gap. Preferably, when the movable baffle 48 moves to the discharge position, an "L"-shaped discharge port is formed between the movable baffle 48 and the first baffle plate 43. The "L"-shaped discharge port is defined by the upper surface of the movable baffle 48 and the side wall of the first baffle plate 43 facing the movable baffle 48. When the powder falls from the discharge port 421, it first contacts the upper surface of the movable baffle 48, and then changes its flow direction along the "L"-shaped path before falling onto the surface of the brick blank. This allows the powder to be evenly dispersed and fall along the "L"-shaped path when it is output through the discharge port, thereby improving the uniformity and spreading effect of the powder discharge.

[0024] Furthermore, to ensure that the movable baffle 48 maintains linear motion without deviation during movement, the fabric feeding mechanism 4 in this embodiment further includes a second baffle plate 44. The second baffle plate 44 is disposed on one side of the first baffle plate 43, and the discharge port 421 is formed between the second baffle plate 44 and the first baffle plate 43. The movable baffle 48 is L-shaped and includes a connecting part 481 and a baffle part 482 that are connected to each other. The connecting part 481 is drively connected to the driver 47, and the side of the baffle part 482 away from the connecting part 481 slides along the second baffle plate 44. Both the first baffle plate 43 and the second baffle plate 44 are fixed to the discharge bin 42 and are spaced apart in the lateral direction. The space between them is the discharge port 421. The connecting portion 481 of the movable baffle 48 is located on the side of the second baffle plate 44 away from the first baffle plate 43. The baffle portion 482 extends from the connecting portion 481 toward the first baffle plate 43 and crosses the discharge port 421. When the driver 47 drives the movable baffle 48 to move, the side of the baffle portion 482 away from the connecting portion 481 abuts against the surface of the second baffle plate 44 and slides along the surface. The second baffle plate 44 provides guidance for the movement direction of the baffle portion 482, so that the movable baffle 48 is guided and constrained by the second baffle plate 44 during the movement, thereby improving the positional accuracy and running stability of the movable baffle 48 during the movement.

[0025] Furthermore, to improve the anti-sway capability of the movable stop bar 48 during reciprocating motion, the fabric feeding mechanism 4 in this embodiment also includes a guide plate 49. The guide plate 49 is fixed on the mounting base 45, and a guide groove is formed between the guide plate 49 and the second baffle plate 44. The movable stop bar 48 is disposed in the guide groove, with one side of the movable stop bar 48 abutting against the second baffle plate 44 and the other side of the movable stop bar 48 abutting against the guide plate 49. The guide plate 49 is a plate-shaped member extending along the movement direction of the movable stop bar 48, and it is parallel to and spaced apart from the second baffle plate 44. The space between the two is the guide groove. The width of the guide groove is adapted to the thickness of the movable stop bar 48, so that the movable stop bar 48 is just accommodated in the guide groove. The guide groove limits the two sides of the movable stop bar 48 through its one side wall, i.e., the surface of the second baffle plate 44, and its other side wall, i.e., the surface of the guide plate 49. When the driver 47 drives the movable stop bar 48 to reciprocate along the movement direction, the movable stop bar 48 slides in the guide groove. Since one side of the movable stop bar 48 abuts against the second baffle plate 44 and the other side abuts against the directional plate 49, the movable stop bar 48 is constrained by the two side walls of the guide groove in the lateral direction and cannot wobble. This makes the movable stop bar 48 subject to the double-sided limiting constraint of the guide groove during the movement, thereby improving the straightness and anti-wobble ability of the movable stop bar 48 during the reciprocating motion.

[0026] In existing technologies, excess powder removed by the dry granule removal mechanism 5 is usually treated directly as waste and cannot be effectively recycled, resulting in serious waste of powder. To address this issue, the dry granule feeding device 6 in this embodiment includes a cyclone separator 61, a vibrating screen mechanism 62, a dry granule storage mechanism 63, and a powder feeder. The discharge end of the dry granule removal mechanism 5 is connected to the input end of the cyclone separator 61 via a pipe (not shown in the figure). The cyclone separator 61 includes a discharge end for outputting powder, which is located above the input end of the vibrating screen mechanism 62. The output end of the vibrating screen mechanism 62 is connected to the dry granule storage mechanism 63 via a pipe (not shown in the figure). The dry granule storage mechanism 63 is connected to the dry granule distribution mechanism 4 via the powder feeder. The airflow containing powder, drawn by the dry granule removal mechanism 5, enters the cyclone separator 61 through a pipeline. The cyclone separator 61 uses centrifugal force to separate the powder from the airflow. The separated powder is discharged from the outlet of the cyclone separator 61 and falls to the input of the vibrating screen mechanism 62. The vibrating screen mechanism 62 sieves the powder to remove any impurities and agglomerated powder. The qualified powder after sieving is transported from the output of the vibrating screen mechanism 62 through a pipeline to the dry granule storage mechanism 63 for storage. The powder feeder pumps the powder in the dry granule storage mechanism 63 through a pipeline to the hopper 41 of the dry granule distribution mechanism 4 for reuse. Through the above-mentioned circulation loop, excess powder drawn by the dry granule removal mechanism 5 can be sequentially separated by the cyclone separator 61, sieved by the vibrating screen mechanism 62, and then recycled back to the dry granule storage mechanism 63 and resupplyed to the dry granule distribution mechanism 4, thereby improving the recycling rate of powder. Preferably, the dry particle removal mechanism 5 is a vacuum generator. The vacuum generator utilizes the high-speed airflow generated when compressed air passes through its internal nozzle to create negative pressure at the inlet, thereby drawing in excess powder that is not adhered to the material and discharging it through the outlet. By using a vacuum generator, the dry particle removal mechanism 5 can utilize compressed air to generate negative pressure to remove excess powder that is not adhered to the material. Compared to the traditional method using a blower, the vacuum generator has the advantages of small size, no moving parts, and rapid response, thus improving the removal efficiency of the dry particle removal mechanism 5. The powder feeder can be a conventional conveying device such as a conveying pump used for conveying powder.

[0027] The working principle of the dry granule fabric production line of the present invention is explained below: The brick blank to be fabricated is placed on the upper surface of the conveyor belt 2. The conveyor belt 2 runs along the conveying direction under the drive of an external drive source, conveying the brick blank sequentially to the area below the glue spraying mechanism 3, the area below the dry granule fabric spreading mechanism 4, and the area below the dry granule suction mechanism 5. First, when the brick blank passes under the glue spraying mechanism 3, the glue spraying mechanism 3 sprays adhesive onto a specific area on the upper surface of the brick blank according to a preset pattern, so that an adhesive pattern area with adhesion is formed on the surface of the brick blank. Then, the brick blank continues to run to the area below the dry granule fabric spreading mechanism 4. The external control system determines the lateral position area to be fabricated according to the glue spraying pattern data of the glue spraying mechanism 3, and controls the multiple sets of movable feeding components arranged side by side in the lateral direction in the dry granule fabric spreading mechanism 4 respectively. The driver 47 of the movable feeding component located at the position corresponding to the glue spraying pattern drives the movable stop bar 48 to move to the discharge position, while the driver 47 of the movable feeding component located in the non-glue spraying area drives the movable stop bar 48 to stay in the blocking position. The dry granule feeding device 6 supplies powder to the hopper 41. The powder enters the discharge hopper 42 through the hopper opening 411. At the movable feeding assembly in the discharge position, the powder is output from the discharge port 421 through the discharge port formed between the movable baffle 48 and the first baffle plate 43 and falls onto the adhesive spraying area on the upper surface of the brick blank. The powder falling into the adhesive area is adhered to the surface of the brick blank by the adhesive, forming the desired pattern or texture. During the horizontal adjustment of each set of movable feeding assemblies, the operator adjusts the horizontal position of each mounting base 45 through the horizontal adjustment structure of each set, so that the horizontal relative position between each movable baffle 48 and the first baffle plate 43 changes, thereby adjusting the discharge width corresponding to each set. During the height adjustment, the operator adjusts the height position of the adjusting base 46 through the height adjustment structure, so that the overall height of the movable baffle 48 and the discharge port 421 changes, thereby adjusting the distance between the discharge port 421 and the brick blank. Subsequently, the brick blank continues to move below the dry granule removal mechanism 5. The dry granule removal mechanism 5 removes excess powder that is loosely accumulated on the surface of the brick blank without being adhered to by the adhesive through its suction port, thus preventing excess powder from entering subsequent processes with the brick blank. The removed excess powder enters the cyclone separator 61 through a pipeline for gas-solid separation. The separated powder enters the vibrating screen mechanism 62 for sieving. The qualified powder after sieving is transported to the dry granule storage mechanism 63 for storage, and then transported back to the hopper 41 of the dry granule distribution mechanism 4 by the powder feeder, realizing the recycling of powder. At this point, the brick blank has completed the complete dry granule distribution process, including adhesive spraying, partial distribution, and excess powder removal.
