Description

Technical Field

[0001] The invention relates to the technical field of tile production distribution systems, in particular to a large particle material truck distribution system. Background Art

[0002] Among ceramic tile products, terrazzo texture patterns are becoming more and more popular among consumers. The pattern texture of traditional terrazzo products is mainly achieved through flat texture decoration using silk screen, roller or inkjet printing technology. Compared with real terrazzo products, the pattern is not three-dimensional and the texture clarity is not realistic enough.

[0003] For example, the Chinese patent with publication number CN114161564A discloses a block powder preparation and random distribution system, including a block powder production unit and a block powder random distribution unit, the block powder production unit includes a first unloading device, a cake pressing device, a dicing device and a main belt, the first unloading device includes a unloading assembly and a secondary belt, and the unloading assembly is arranged in parallel above the belt, the block powder random distribution unit includes a swinging device and a spreading device, and the unloading end of the swinging device can reciprocate along the width direction of the spreading device.

[0004] However, the above scheme has the following shortcomings: in the above patent, the powder is fed to the main belt by the first feeding device to form a powder layer, the powder layer is pressed into powder cakes by the cake pressing device, and the powder cakes are cut into blocks by the dicing device. However, in the process of dicing the powder cakes by the dicing device, since the powder cakes are pressed by powder, when the pressing in the previous step does not complete the compaction of the powder, the rotating roller and the cutting blade in the dicing device may cause the powder to be squeezed and adhered to the surface of the rotating roller or the cutting knife when cutting the uncompacted powder cake, so that when the rotating roller and the cutting knife cut the next powder cake, the divided material adhered to the rotating roller or the cutting knife may squeeze the cut powder cake, causing the powder cake to break and crack. For this reason, we have introduced a large-particle material cart feeding system. Summary of the invention

The second feeding conveyor belt 13 transports the materials in the third storage hopper 11 to the second mixing hopper 10 for mixing, and lays them on the bottom material of the second cloth conveyor belt 2;

[0033] The flattening and slicing mechanism 100 includes a flattening device 14 and a slicing roller 26. The slicing roller 26 is arranged on the inner side of a mounting frame 23. The mounting frame 23 is fixedly connected to the flattening device 14. A plurality of groups of slicing grooves 27 are provided on the outer side of the slicing roller 26. The plurality of groups of slicing grooves 27 are arranged in irregular shapes. The flattened material is cut into material blocks of different shapes by the plurality of groups of slicing grooves 27. A scraping hopper 24 is fixedly connected to one side of the mounting frame 23. The scraping hopper 24 contacts the outer side of the slicing roller 26. When the rubber sheet 28 moving outward moves to the position of the scraping hopper 24, the scraping hopper 24 scrapes the rubber sheet 28, so that the material adhering to the surface of the rubber sheet 28 is scraped into the scraping hopper 24.

[0034] A rubber plate 28 is movably connected in the block cutting groove 27, and the shape of the rubber plate 28 corresponds to that of the block cutting groove 27. The end of the rubber plate 28 close to the block cutting roller 26 is fixedly connected to the sealing folding ring 15, and the end of the sealing folding ring 15 away from the rubber plate 28 is fixedly connected to the block cutting groove 27. The block cutting groove 27 is connected to the air storage chamber 30 through two groups of through holes 35. The through holes 35 and the air storage chamber 30 are both provided in the block cutting roller 26. The extrusion plate 31 moves to push the air in the air storage chamber 30 into the block cutting groove 27. At this time, the rubber plate 28 will move outward, and the material adhered to the block cutting groove 27 will be pushed out by the movement of the rubber plate 28. When the extrusion plate 31 moves inward, the air entering the block cutting groove 27 will be re-drawn into the air storage chamber 30. The rubber plate 28 moves inward and drives the sealing folding ring 15 to move, so that the sealing folding ring 15 changes from the unfolded state to the folded state.

[0035] An extrusion plate 31 is movably connected in the air storage chamber 30, and a connecting rod 32 is fixedly connected near one end of the extrusion plate 31. The end of the connecting rod 32 away from the rubber plate 28 extends into the cavity 34 and is fixedly connected to the pulley 36. The cavity 34 is opened in the cutting roller 26. A support rod 33 is movably connected in the cavity 34. An extrusion block 29 is fixedly connected to one side of the support rod 33. One end of the support rod 33 extends out of the cutting roller 26 and is fixedly connected to the mounting frame 23, so that when the cutting roller 26 rotates, the support rod 33 will not rotate with it. When the cutting roller 26 rotates, the support rod 33 is connected to the connecting rod 32. The connected pulley 36 will contact the extrusion block 29, and the connecting rod 32 will drive the extrusion plate 31 to move along the air storage chamber 30. The outer side of the connecting rod 32 is sleeved with a spring 4, one end of the spring 4 is fixedly connected to the pulley 36, and the other end is fixedly connected to the cavity 34. When the rubber plate 28 passes through the scraper hopper 24, the pulley 36 is no longer in contact with the extrusion block 29. At this time, under the elastic force of the spring 4, the connecting rod 32 moves inward and the extrusion plate 31 moves synchronously. One end of the mounting frame 23 is fixedly connected to the transmission motor 25, and the output end of the transmission motor 25 passes through the mounting frame 23 and is fixedly connected to the cutting roller 26;

[0036] The powder recovery mechanism includes a first recovery conveyor belt 21, which is fixedly connected to the bracket 1. A second recovery conveyor belt 12 is provided on the lower side of the first recovery conveyor belt 21, and the second recovery conveyor belt 12 is fixedly connected to the bracket 1. The second recovery conveyor belt 12 is arranged on the upper side of the feed hopper 6 away from one end of the first recovery conveyor belt 21. The leaked powder is conveyed to the second recovery conveyor belt 12 through the first recovery conveyor belt 21, and the second recovery conveyor belt 12 puts the recovered powder back into the feed hopper 6.

[0037] Working principle: when in use, the bottom material is conveyed to the top of the first cloth conveyor belt 22 through the feeding hopper 6, the first cloth conveyor belt 22 drives the bottom material to move, and conveys the bottom material to the bottom hopper 20, and the three groups of first storage hoppers 7 convey the material to the top of the first feeding conveyor belt 5, and the first feeding conveyor belt 5 conveys the material in the first storage hopper 7 to the first mixing hopper 8 for mixing, and the material mixed by the first mixing hopper 8 enters the carved feeding device 3 and falls onto the surface of the second cloth conveyor belt 2, and at the same time, the carved roller rotating in the carved feeding device 3 creates a gap in the material falling onto the surface of the second cloth conveyor belt 2, so as to facilitate the mixing of the material with materials of other colors;

[0038] Two groups of second storage hoppers 9 lay materials of different colors on top of the materials on the second cloth conveyor belt 2. The second feeding conveyor belt 13 transports the materials in the third storage hopper 11 to the second mixing hopper 10 for mixing and lays them on top of the bottom material of the second cloth conveyor belt 2, so that the materials have a sense of layering. The flattening device 14 first performs a sweeping process on the surface of the materials and then flattens them. The rotation of the transmission motor 25 drives the cutting roller 26 to rotate. When the flattened materials move between the second cloth conveyor belt 2 and the cutting roller 26, a plurality of groups of cutting grooves 27 cut the flattened materials, and the cut materials fall into the upper end of the feeding conveyor belt 18.

[0039] During the rotation of the cutting roller 26, the pulley 36 connected to the connecting rod 32 will contact the extrusion block 29. At this time, the connecting rod 32 will drive the extrusion plate 31 to move along the air storage chamber 30. The movement of the extrusion plate 31 pushes the air in the air storage chamber 30 into the cutting groove 27. At this time, the rubber plate 28 will move outward, and the material adhered to the cutting groove 27 will be pushed out by the movement of the rubber plate 28. When the outward moving rubber plate 28 moves to the position of the scraping hopper 24, the scraping hopper 24 will scrape the rubber plate 28, so that the material adhered to the rubber The material on the surface of the plate 28 is scraped into the scraper hopper 24. After the rubber plate 28 passes through the scraper hopper 24, the pulley 36 is no longer in contact with the extrusion block 29. At this time, under the elastic force of the spring 4, the connecting rod 32 moves inward and the extrusion plate 31 moves synchronously. At this time, the air entering the cutting groove 27 will be re-injected into the air storage chamber 30. The rubber plate 28 moves inward and drives the sealing folding ring 15 to move, so that the sealing folding ring 15 changes from the unfolded state to the folded state. At this time, the cutting groove 27 can cut the flattened material again;

[0040] The material blocks of different sizes are transported to the top of the pressing conveyor plate 19 through the feeding conveyor belt 18. After the bottom hopper 20 distributes the material to the grid, the pressing conveyor plate 19 feeds the material between the upper mold 16 and the lower mold 17 together, so that the bottom material and the block materials of different sizes are pressed together. During the movement of the pressing conveyor plate 19, the feeding conveyor belt 18 will stop, and the leaked powder will be transported to the second recovery conveyor belt 12 through the first recovery conveyor belt 21. The second recovery conveyor belt 12 will put the recovered powder back into the feeding hopper 6.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
