During the conveying process, the product is pushed by the correction unit 5 to adjust the position of the product on the conveyor belt 2 so that the product is located at the center of the conveyor belt 2. The product during the conveying process is limited by the limiting unit 4 to effectively prevent the product from tilting during the conveying process. During the conveying process, the tensioning adjustment unit 3 drives the driven roller 6 to move, so as to adjust and correct the tension of the conveyor belt 2, effectively preventing the conveyor belt 2 from running off and causing the conveyed product to tilt;

[0033] The tensioning adjustment unit 3 includes a slide groove 31 and a displacement assembly, which are both arranged on both sides of the mounting frame 1. A mounting seat 32 is slidably installed in the slide groove 31, and the mounting seat 32 is rotatably connected to the driven roller 6. The mounting seat 32 is connected to the displacement assembly. A crossbeam 35 is installed on the mounting seat 32, and a detection assembly is arranged on the crossbeam 35. The detection assembly is slidably connected to the conveyor belt 2, such as Figure 3 , Figure 8 As shown, the tension of the conveyor belt 2 is monitored by the detection component. During operation, when the conveyor belt 2 is extended or worn, the tension of the conveyor belt 2 changes, the pressure applied by the conveyor belt 2 to the detection component changes, and the detection value of the detection component exceeds the set range. At this time, the conveyor belt 2 needs to be adjusted, and the mounting seat 32 is driven by the displacement component to slide in the slide groove 31, and the mounting seat 32 drives the driven roller 6 to move, so that the driven roller 6 tensions the conveyor belt 2, thereby timely correcting the conveyor belt 2, effectively avoiding the deviation of the conveyor belt 2 due to the extension of the conveyor belt 2, and avoiding the deviation of the products on the conveyor belt 2 due to the deviation of the conveyor belt 2, thereby improving the convenience and timeliness of the tension adjustment of the conveyor belt 2, avoiding injuries during adjustment, and improving safety;

[0034] The limiting unit 4 includes a bracket 41 and a two-way adjustment component. The bracket 41 is mounted on the mounting frame 1, and the two-way adjustment component is mounted on the bracket 41. Two slide plates 44 are mounted on the two-way adjustment component.

Figure 1 , Figure 5 , Figure 7 As shown, according to the size of the conveyed product, the two slide plates 44 are driven to move by the two-way adjustment component, and the two slide plates 44 respectively drive the two limit plates 45 to move, so as to adjust the distance between the two limit plates 45, and the products on the conveyor belt 2 are limited and guided by the two limit plates 45, so as to effectively prevent the products from being deflected during the conveying process;

[0035] The deviation correction unit 5 includes a mounting groove 55 and a guide belt 54. The mounting groove 55 is arranged at the end of the limiting plate 45. Two rollers 53 are rotatably mounted in the mounting groove 55. A brake assembly is arranged inside the mounting groove 55. The two rollers 53 are connected by transmission through the guide belt 54. The brake assembly is frictionally connected to the rollers 53. Figure 1 , Figure 2 , Figure 7As shown, the product on the conveyor belt 2 is guided by the guide belt 54. When the conveyor belt 2 drives the product to move, the friction between the product and the guide belt 54 causes the guide belt 54 to rotate. The posture of the product conveyed on the conveyor belt 2 is judged according to the tension of the conveyor belt 2. According to the posture of the product on the conveyor belt 2, the roller 53 is frictionally braked by the brake assembly, and the speed of the guide belt 54 is slowed down, so that the guide belt 54 blocks the product in the reverse direction, making the speed of the guide belts 54 on both sides of the product inconsistent, thereby making the conveying speed on both sides of the product inconsistent, and adjusting the posture of the product through the conveying speed difference, so that the product is conveyed in a suitable posture, and the deviation correction of the product is completed, thereby improving the convenience and efficiency of product deviation correction.

[0036] The brake assembly in the mounting groove 55 includes a hydraulic cylinder 51, which is arranged in the mounting groove 55. A brake pad 52 is installed on the telescopic end of the hydraulic cylinder 51. The brake pad 52 is frictionally connected to the roller 53. The hydraulic cylinder 51 is electrically connected to the external controller. The hydraulic cylinder 51 works by using existing technologies, such as Figure 2 As shown, when the guide belt 54 needs to be decelerated, the brake pad 52 is driven to move by the hydraulic cylinder 51 so that the brake pad 52 contacts the roller 53. By increasing the friction between the brake pad 52 and the roller 53, the rotation speed of the roller 53 is slowed down, thereby slowing down the speed of the guide belt 54.

[0037] The detection assembly on the crossbeam 35 includes a pressure sensor 36. An installation cavity is equidistantly arranged in the crossbeam 35. The pressure sensor 36 is installed in the installation cavity. A slide bar 38 is slidably installed on the crossbeam 35. A top plate 37 is installed on the upper end of the slide bar 38 located in the installation cavity. A placement frame 310 is installed on the lower end of the slide bar 38. A spring 39 is sleeved on the part of the slide bar 38 located between the crossbeam 35 and the placement frame 310. A tensioning roller 311 is rotatably installed on the placement frame 310. The tensioning roller 311 is slidably connected to the conveyor belt 2. The pressure sensor 36 is electrically connected to the external controller. The pressure sensor 36 works using existing technologies, such as Figure 4 , Figure 8As shown, the tensioning roller 311 is attached to the conveyor belt 2 through the spring 39, and the conveyor belt 2 pushes the slide bar 38 and the top plate 37 in the opposite direction through the tensioning roller 311 and the placement frame 310, so that the top plate 37 squeezes the pressure sensor 36, and the tensioning force of the conveyor belt 2 is monitored by the pressure detected by the pressure sensor 36. During the working process, when the conveyor belt 2 is extended or worn, the tension of the conveyor belt 2 changes. Due to the elastic force of the spring 39, when the tension of the conveyor belt 2 changes, the conveyor belt 2 exerts pressure on the pressure sensor 36. When the pressure changes, the value detected by the pressure sensor 36 exceeds the set range. At this time, the conveyor belt 2 needs to be adjusted. The displacement component drives the mounting seat 32 to slide in the slide groove 31, and the mounting seat 32 drives the driven roller 6 to move, so that the driven roller 6 tensions the conveyor belt 2, thereby timely correcting the conveyor belt 2, effectively avoiding the deviation of the conveyor belt 2 due to the extension of the conveyor belt 2, and avoiding the deviation of the products on the conveyor belt 2 due to the deviation of the conveyor belt 2, thereby improving the convenience and timeliness of the tension adjustment of the conveyor belt 2, avoiding injuries during adjustment, and improving safety.

[0038] The displacement assembly in the tension adjustment unit 3 includes a lead screw 33 and a first motor 34. The lead screw 33 is rotatably mounted on both sides of the mounting frame 1. The lead screw 33 is threadedly connected to the mounting seats 32 on both sides of the mounting frame 1. The first motor 34 is arranged on both sides of the mounting frame 1.

The first motor 34 works by using existing technologies, such as Figure 3 , Figure 6 , Figure 8 As shown, when the tension of the conveyor belt 2 needs to be adjusted, the first motor 34 drives the lead screw 33 to rotate, and the lead screw 33 drives the mounting seat 32 to move, thereby driving the driven roller 6 to move, so that the driven roller 6 tensions the conveyor belt 2, effectively improving the convenience and safety during adjustment.

[0039] The bidirectional adjustment assembly in the limiting unit 4 includes a second motor 42 and a bidirectional screw 43. The second motor 42 is mounted on the bracket 41. The bidirectional screw 43 is rotatably mounted on the bracket 41. The bidirectional screw 43 is connected to the output shaft of the second motor 42. The two ends of the bidirectional screw 43 have opposite screw directions. The two ends of the bidirectional screw 43 have opposite screws connected to the slide plate 44 respectively. The second motor 42 is electrically connected to the external controller. The second motor 42 works using existing technologies, such as Figure 1 , Figure 5 As shown, the bidirectional screw 43 is driven to rotate by the second motor 42, and the slide plate 44 is driven to move by the bidirectional screw 43, so that the distance between the two limit plates 45 is adjusted according to the size of the conveyed product, so that the limit plates 45 can better limit and guide the product, thereby improving the convenience of adjustment and the scope of use.

[0040] Optical films 10 are disposed on opposite sides of the two limiting plates 45. Figure 1 , Figure 2 As shown, the limiting plate 45 is protected by the optical film 10, and at the same time the smoothness of the surface of the limiting plate 45 is improved, effectively reducing the friction between the product and the limiting plate 45, so that the limiting plate 45 can better limit the product and avoid the limiting plate 45 affecting the transportation of the product.

[0041] A chassis 8 is mounted on the mounting seat 32, and a sliding sleeve 9 is rotatably mounted on the chassis 8. The chassis 8 and the sliding sleeve 9 are both slidably sleeved on the driven roller 6. The sliding sleeve 9 is located on both sides of the conveyor belt 2. Figure 3 , Fig. 9 As shown, the conveyor belt 2 is limited by the chassis 8 and the sliding sleeve 9, which effectively prevents the conveyor belt 2 from being deflected. Due to the rotational connection between the chassis 8 and the sliding sleeve 9, when the conveyor belt 2 rotates, the conveyor belt 2 drives the sliding sleeve 9 to rotate on the chassis 8, thereby protecting the conveyor belt 2 and effectively reducing the wear and deformation of the edge of the conveyor belt 2.

[0042] Working principle: Figure 1 , Figure 5 As shown, according to the size of the conveyed product, the bidirectional screw 43 is driven to rotate by the second motor 42, and the slide plate 44 is driven to move by the bidirectional screw 43, and the two slide plates 44 respectively drive the two limit plates 45 to move, so as to adjust the distance between the two limit plates 45;

[0043] like Figure 1 , Figure 5 , Figure 7 As shown, the product is placed on the conveyor belt 2, and the external driving component drives the active roller 7 to rotate. The active roller 7 cooperates with the driven roller 6 to drive the conveyor belt 2 to rotate, and the product is transported by the conveyor belt 2; during the transportation process, Figure 1 , Figure 2 , Figure 7 As shown, the guide belt 54 is used to guide and limit the product on the conveyor belt 2, so that the product is located in the middle of the conveyor belt 2. When the conveyor belt 2 drives the product to move, the friction between the product and the guide belt 54 causes the guide belt 54 to rotate;

[0044] like Figure 1 , Figure 5 , Figure 7 As shown, the conveyor belt 2 drives the product to enter between the two limit plates 45, and the two limit plates 45 limit and guide the product on the conveyor belt 2; at the same time, as shown Figure 1 , Figure 2 As shown, the limit plate 45 is protected by the optical film 10, and the friction between the product and the limit plate 45 is reduced by the optical film 10, so as to prevent the limit plate 45 from affecting the conveyed product;

[0045] During the product conveying process of conveyor belt 2, Figure 3 , Fig. 9 As shown, the conveyor belt 2 is limited by the chassis 8 and the sliding sleeve 9. When the conveyor belt 2 rotates, the conveyor belt 2 drives the sliding sleeve 9 to rotate on the chassis 8, thereby protecting the conveyor belt 2 and effectively reducing the wear and deformation of the edge of the conveyor belt 2;

[0046] At the same time, during the conveying process of the product by the conveyor belt 2, Figure 4 , Figure 8 As shown, the tensioning roller 311 is attached to the conveyor belt 2 through the spring 39, and the conveyor belt 2 pushes the slide bar 38 and the top plate 37 in the opposite direction through the tensioning roller 311 and the placement frame 310, so that the top plate 37 squeezes the pressure sensor 36, and the tensioning force of the conveyor belt 2 is monitored by the pressure detected by the pressure sensor 36;

[0047] When the conveyor belt 2 is stretched or worn, the tension of the conveyor belt 2 changes, such as Figure 3 , Figure 4 , Figure 8 As shown, due to the elastic force of the spring 39, when the tension of the conveyor belt 2 changes, the pressure applied by the conveyor belt 2 to the pressure sensor 36 changes. When the value detected by the pressure sensor 36 exceeds the set range, as shown in FIG. Figure 3 , Figure 6 , Figure 8 As shown, the first motor 34 drives the lead screw 33 to rotate, the lead screw 33 drives the mounting seat 32 to move, and the mounting seat 32 drives the driven roller 6 to move, so that the driven roller 6 tensions the conveyor belt 2, and corrects the conveyor belt 2 in time, effectively avoiding the conveyor belt 2 from running off due to the extension of the conveyor belt 2;

[0048] When the tension of the conveyor belt 2 changes, the posture of the product being conveyed on the conveyor belt 2 will change. The pressure sensor 36 detects the change in the tension pressure on both sides of the conveyor belt 2, thereby determining the posture of the product on the conveyor belt 2. Figure 1 , Figure 2 , Figure 7 As shown, according to the posture of the product on the conveyor belt 2, the brake pad 52 is driven to move by the hydraulic cylinder 51, so that the brake pad 52 contacts the roller 53, so that the brake pad 52 brakes the roller 53, and the speed of the guide belt 54 is slowed down. The brake pad 52 brakes the roller 53, so that the speed of the guide belt 54 on both sides of the product is inconsistent, so that the guide belt 54 blocks the product in the reverse direction, so that the conveying speed on both sides of the product is inconsistent, and the posture of the product is adjusted by the conveying speed difference, so that the product is conveyed in a suitable posture, the deviation correction of the product is completed, and the convenience and efficiency of product deviation correction are improved.
