The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figures 1 to 10 As shown, the material conveying device of the present invention includes a frame 10, a conveyor belt 11, a separation frame 20, a partition 30, an adjustment mechanism 40, a recovery box 50, a cleaning component 60, an absorption component 70, a transmission mechanism 80 and a stripping mechanism 90. The conveyor belt 11 is arranged in the frame 10 for conveying materials. The separation frame 20 is arranged in the frame 10 and can move back and forth relative to the conveyor belt 11 to separate the material from the conveyor belt 11. There are multiple partitions 30 arranged above the conveyor belt 11. Under the adjustment of the adjustment mechanism 40, they can move closer to or away from each other, adjust the distance between adjacent partitions 30, and then isolate the material to avoid the material from being skewed during transportation, resulting in falling and stacking. The recovery box 50 is arranged below the frame 10. With the cooperation of the cleaning component 60 and the absorption component 70, the material residues, flour, etc. that fall and adhere to the surface of the conveyor belt 11 can be recovered.

[0030] refer to Figure 1 and Figure 2 A base 12 is fixedly installed at the bottom of the frame 10, and a support 13 located at the discharge end of the conveyor belt 11 is fixedly installed on the frame 10 for supporting the stripping mechanism 90.

[0031] The material of the conveyor belt 11 is food grade silicone, and the surface of the conveyor belt 11 is provided with protrusions, which can reduce the contact area between the conveyor belt 11 and the material, reduce the adhesion of the material, and increase the friction on the surface of the conveyor belt 11, so as to better convey the material for movement.

[0032] In order to facilitate understanding of the present invention, it is defined in the present invention that the conveying direction of the conveyor belt 11 is the transverse direction, and the conveying direction perpendicular to the horizontal direction of the conveyor belt 11 is the longitudinal direction.

[0033] refer to Figure 1 、 Figure 4 as well as Figure 5 The separation frame 20 includes a side plate 21, a scraper 22 and a connecting rod 23. The side plate 21 is arranged on one side of the frame 10, and the scraper 22 is fixedly installed on the side plate 21. There are multiple scrapers 22 equidistantly distributed along the conveying direction of the conveyor belt 11, and the bottom of the scraper 22 is set close to the top of the conveyor belt 11, which can separate the material from the conveyor belt 11 during transportation. The connecting rod 23 is vertically fixed to the side wall of the side plate 21, and the connecting rod 23 is slidably assembled inside the frame 10, which can drive the side plate 21 close to or away from the frame 10, and then make the scraper 22 slide longitudinally relative to the conveyor belt 11, which can apply longitudinal shear force to the transversely conveyed material, and then make the material better separated from the conveyor belt 11.

[0034] refer to Figure 5 A pushing shaft 231 is provided on one side of the connecting rod 23, and the pushing shaft 231 is rotatably assembled in the frame body 10. A spiral guide groove 232 is provided on the side wall of the pushing shaft 231, and a sliding shaft 233 is slidably assembled inside the guide groove 232, and the sliding shaft 233 is fixedly installed on the connecting rod 23. When the pushing shaft 231 rotates, the guide groove 232 pushes the sliding shaft 233 to move, and then drives the connecting rod 23 to slide in the frame body 10, so that the side plate 21 moves with the scraper 22, applying a longitudinal shear force to the material. The guide groove 232 is a closed-loop groove connected from head to tail, so that when the pushing shaft 231 continues to rotate, it can push the sliding shaft 233 to slide back and forth, and then make the connecting rod 23 push the scraper 22 back and forth.

[0035] refer to Figure 1 、 Figure 2 、 Figure 4 as well as Figure 9, multiple partitions 30 are equidistantly distributed along the length direction of the scraper 22, so that the multiple partitions 30 form multiple conveying paths to separate and block the materials, and prevent the materials from tilting and falling during transportation. A notch 31 is provided at the bottom of the partition 30, and the partition 30 is slidably assembled on the outside of the scraper 22 through the notch 31. The top of each partition 30 is fixedly mounted on the hanging plate 32 to drive the partition 30 to slide on the scraper 22, and then adjust the distance between adjacent partitions 30 to adapt to the conveying limit of materials of different sizes. The material of the partition 30 is food-grade plastic with a smooth surface, not easy to stick to the material and light weight, which is easy to adjust.

[0036] refer to Figure 5 、 Figure 7 、 Figure 8 as well as Figure 9 The adjusting mechanism 40 includes an adjusting box 41, a support plate 42, a telescopic sleeve 43, a push plate 44 and a double-headed screw 45. The adjusting box 41 is fixedly installed on the top of the frame 10. There are multiple support plates 42, all of which are arranged inside the adjusting box 41. Multiple support plates 42 are respectively fixed one-to-one with the hanging plates 32 on the multiple partitions 30, and the support plates 42 can slide longitudinally inside the adjusting box 41 to drive the hanging plates 32 to move. There are multiple telescopic sleeves 43 respectively arranged between two adjacent support plates 42, there are two push plates 44, and multiple support plates 42 are located between the two push plates 44. The double-headed screw 45 is rotatably connected to the inside of the adjusting box 41. The two push plates 44 are respectively threaded at the two ends of the double-headed screw 45 and can be pushed closer to or away from each other when the double-headed screw 45 rotates. When the two push plates 44 approach each other, they can push the support plate 42 to compress the telescopic sleeve 43, and then the multiple support plates 42 gradually move closer to each other in the adjustment box 41, and the distance between the multiple support plates 42 is reduced; when the two push plates 44 move away from each other, the telescopic sleeve 43 extends and pushes the support plates 42 to gradually disperse to both sides, and then the multiple support plates 42 gradually move away from each other in the adjustment box 41, and the distance between the multiple support plates 42 is increased, which can better adjust the limit spacing between the two partitions 30 according to the size of the material.

[0037] A slide groove 411 is provided at the bottom of the adjustment box 41, and the hanging plate 32 is slidably assembled inside the slide groove 411. A guide rod 412 is fixedly connected to the inside of the adjustment box 41. The support plate 42 and the push plate 44 are both slidably assembled on the guide rod 412. The guide rod 412 guides the support plate 42 and the push plate 44 to slide in the adjustment box 41. A through hole 421 is provided in the middle of the support plate 42, and the double-headed screw 45 passes through the through hole 421 of the support plate 42.

[0038] refer to Figure 8 and Figure 10The telescopic sleeve 43 is composed of a sleeve 431, a sliding rod 432 and a piston block 433. The sleeve 431 and the sliding rod 432 are respectively fixed on two adjacent support plates 42, and the sliding rod 432 is slidably assembled inside the sleeve 431. The piston block 433 is fixedly installed at the end of the sliding rod 432 for sealing between the sleeve 431 and the sliding rod 432. When the sliding rod 432 gradually slides into the sleeve 431 after being subjected to external force, the piston block 433 can compress the gas inside the sleeve 431, and the air pressure gradually increases. When the external thrust applied to the sliding rod 432 gradually decreases, the high-pressure gas in the sleeve 431 can push the sliding rod 432 out, so that the sliding rod 432 gradually extends from the sleeve 431. Therefore, the distance between the multiple support plates 42 can be adjusted by the extension and contraction of the sliding rod 432 in the sleeve 431.

[0039] refer to Figure 4 and Figure 5 The recycling box 50 includes an upper box body 51, a lower box body 52, a U-shaped tube 53 and a connecting tube 54. The upper box body 51 and the lower box body 52 are both fixed on the support 13, and the lower box body 52 is located below the upper box body 51. Both ends of the U-shaped tube 53 are inserted into the top of the lower box body 52 and are connected to the interior of the lower box body 52. The connecting tube 54 is inserted into the middle of the U-shaped tube 53, and the top end of the connecting tube 54 is inserted into the interior of the upper box body 51, so that the upper box body 51 and the U-shaped tube 53 are connected.

[0040] refer to Figure 5 The cleaning assembly 60 includes a central shaft 61, a brush roller 62 and a motor 63. The central shaft 61 is longitudinally rotated and assembled inside the upper box body 51. The brush roller 62 is coaxially fixed to the outside of the central shaft 61, and the top of the brush roller 62 is set close to the bottom surface of the conveyor belt 11. The motor 63 is fixedly installed on the outside of the recovery box 50, and the output shaft of the motor 63 is fixed to the central shaft 61, which can drive the central shaft 61 to rotate, and then the brush roller 62 rotates to clean the surface of the conveyor belt 11, and clean the material debris and flour adhering to the conveyor belt 11, and the upper box body 51 is used for recovery.

[0041] refer to Figure 5The absorbing assembly 70 includes a sealing plug 71, a sealing plate 72, an elastic member 73 and a one-way valve 74. The sealing plug 71 is slidably assembled inside the lower box body 52 and is located between the two pipe openings of the U-shaped tube 53. The sealing plate 72 has two pieces respectively arranged in the two pipe openings of the U-shaped tube 53 for sealing the pipe opening of the U-shaped tube 53. The elastic member 73 is arranged between the sealing plate 72 and the U-shaped tube 53, and can apply a pulling force to the sealing plate 72 in the direction of the U-shaped tube 53 so that the sealing plate 72 keeps blocking the U-shaped tube 53. In this solution, the elastic member 73 is specifically a spring, and its two ends are respectively fixed to the U-shaped tube 53 and the sealing plate 72. There are multiple one-way valves 74 respectively arranged at both ends of the lower box body 52, and all of them can be opened as the air pressure in the lower box body 52 increases, thereby discharging flour. A filter bag (not shown in the figure) is provided at one end of the one-way valve 74 away from the lower box body 52, which can collect the discharged flour.

[0042] As the sealing plug 71 moves in the lower box body 52, the front end of the lower box body 52 gradually moves away from the sealing plug 71, forming a negative pressure inside, and the sealing plate 72 in the mouth of the U-shaped tube 53 at this end is sucked into the lower box body 52, so that the mouth of the U-shaped tube 53 at the front end of the lower box body 52 opens, and then the air and flour in the upper box body 51 are sucked into the lower box body 52. At the same time, the rear end of the lower box body 52 gradually approaches the sealing plug 71, the internal air is compressed, and the air pressure gradually increases, causing the one-way valve 74 at this end to open, and the air is discharged, and then the lower box body 52 forms a state of front-end air intake and rear-end exhaust. When the exhaust After completion, the sealing plug 71 moves back, and the sealing plate 72 is reset under the action of the elastic member 73, closing the pipe mouth of the U-shaped tube 53 at the front end of the lower box body 52 again. At the same time, the one-way valve 74 at the rear end of the lower box body 52 is also closed again. As the sealing plug 71 continues to move, the air at the front end of the lower box body 52 is compressed, and a negative pressure is formed inside the rear end, which then forms a state of exhaust at the front end and air intake at the rear end inside the lower box body 52. In this way, through the reciprocating movement of the sealing plug 71 in the lower box body 52, the two ends of the lower box body 52 can be alternately exhausted, so as to better collect and process the flour.

[0043] refer to Figure 4-Figure 6 The lower box body 52 is internally rotated and equipped with a reciprocating screw 521, and a slider 522 is provided on the outside of the reciprocating screw 521, and the slider 522 is fixedly installed in the sealing plug 71. The slider 522 can move back and forth along the threaded groove on the outside of the reciprocating screw 521 as the reciprocating screw 521 rotates, thereby driving the sealing plug 71 to slide back and forth in the lower box body 52 to achieve flour absorption and discharge. A limiting rod 523 is also fixedly installed inside the lower box body 52, and the sealing plug 71 is slidably assembled on the outside of the limiting rod 523. A stepped groove 531 is provided at the end of the U-shaped tube 53, and the sealing plate 72 is arranged inside the stepped groove 531 to facilitate the limiting of the sealing plate 72 so that the sealing plate 72 will not enter the U-shaped tube 53.

[0044] refer to Figure 1 and Figure 4 The transmission mechanism 80 includes a driving pulley 81, a driven pulley 82 and a transmission belt 83. The driving pulley 81 is fixedly mounted on the end of the central shaft 61. The driven pulley 82 has two ends respectively fixedly mounted on the push shaft 231 and the reciprocating screw 521. The transmission belt 83 is mounted between the driving pulley 81 and the driven pulley 82. When the central shaft 61 rotates, the driving pulley 81 can drive the two driven pulleys 82 to rotate through the transmission belt 83, thereby rotating the push shaft 231 and the reciprocating screw 521.

[0045] refer to Figure 1 and Figure 2 The unloading mechanism 90 includes an air pipe 91 and an air nozzle 92. The air pipe 91 is fixed horizontally inside the support 13. There are multiple air nozzles 92 distributed equidistantly on the air pipe 91, and the air outlet of the air nozzle 92 is tilted at the discharge end of the conveyor belt 11. An air compressor pump is provided at the end of the air pipe 91. The pressure of the air compressor pump can be adjusted between 0.2-0.5 MPa. When the material moves to the discharge end of the conveyor belt 11, the air compressor pump can deliver high-pressure gas into the air pipe 91 and blow it out from the air nozzle 92, blowing the material away from the conveyor belt 11 and into the next process, further avoiding the material sticking to the conveyor belt 11 during discharging, and improving the material conveying and discharging effect.

[0046] Working principle: The material is transported through the conveyor belt 11, and the double-headed screw 45 is rotated to make the two push plates 44 approach each other, pushing the support plate 42 to move the partition 30, and compressing the telescopic sleeve 43, and then adjusting the distance between adjacent partitions 30 to a suitable distance, and the partition 30 separates and blocks the material being transported.

[0047] The push shaft 231 is rotated, and the guide groove 232 pushes the sliding shaft 233 to move with the connecting rod 23, so that the connecting rod 23 drives the side plate 21 to move, so that the scraper 22 moves longitudinally, exerts a longitudinal shear force on the transversely transported material, and separates the material from the conveyor belt 11. At the same time, the partition 30 blocks the material on the side, making it unable to move with the scraper 22, thereby improving the material separation effect.

[0048] The central shaft 61 drives the brush roller 62 to rotate along the bottom of the conveyor belt 11, and the material debris, flour, etc. adhering to the surface of the conveyor belt 11 are cleaned and received by the upper box body 51. While the central shaft 61 rotates, it drives the reciprocating screw 521 to rotate, pushing the sealing plug 71 to move back and forth in the lower box body 52, and using negative pressure to suck the flour in the upper box body 51 into the lower box body 52, and using boost pressure to open the one-way valve 74 to recover the flour.

[0049] In the present invention, during material transportation, after the partition 30 separates and limits the material, it can effectively prevent the material from tilting and falling during transportation, and in conjunction with the longitudinally moving scraper 22, it can better scrape the material to separate the material from the conveyor belt 11, thereby avoiding the material from contacting the conveyor belt 11 for a long time and causing adhesion, so that the conveyor belt 11 can be better unloaded; during material transportation, the surface of the conveyor belt 11 can be better cleaned to ensure that the surface of the conveyor belt 11 is clean and tidy, thereby reducing the stickiness of the material and the probability of material adhesion, and can better collect and recycle the cleaned debris, flour, etc., thereby improving the environmental performance of the equipment and facilitating the maintenance of a good production environment in the workshop.
