DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In this application, if Figures 1 to 5As shown, the roller conveyor 1 can convey the load. The front and rear ends of the roller conveyor 1 along the conveying direction are provided with long rollers 2, and the middle section is provided with short rollers 3. The short rollers 3 can be unpowered rollers or self-powered electric rollers. Two groups of short rollers 3 are provided on both sides of the conveying length direction of the roller conveyor. The long rollers 2 can be driven by a motor or can be powered electric rollers. A vertical spacing portion 4 is formed between the two groups of short rollers 3. The lifting mechanism is provided below the spacing portion 4, and can lift the load located in the spacing portion 4, so that it can be raised or lowered vertically, which is convenient for the processing operation of the load. The distance adjustment mechanism can act on the lifting mechanism to limit the maximum lifting stroke of the lifting mechanism, and can stop the lifting of the load at a preset height. When the preset height needs to be changed, the lifting stroke can be controlled by adjusting the distance adjustment mechanism.

[0026] In some embodiments, Figure 5 and Figure 6 As shown, the lifting mechanism includes a cylinder 5, a lifting base plate 6 and a fixed bracket 7. The fixed bracket 7 is fixedly connected to the ground to play a supporting role. The fixed end of the cylinder 5 is fixedly connected to the fixed bracket 7. The free end of the cylinder 5 is upward and connected to the lower surface of the lifting base plate 6 through a transition piece 8. The lifting base plate 6 is arranged in the vertical space where the spacer 4 is located. When it is in the initial position, that is, the cylinder 5 is in a low stroke position, the upper surface of the lifting base plate 6 is lower than the conveying surface of the roller conveyor 1. When the cylinder 5 is in a high stroke position, the lifting base plate 6 is driven by the cylinder 5 to move vertically upward.

[0027] In some embodiments, Figure 5 and Figure 6 As shown, the distance adjustment mechanism includes a first limit assembly and a second limit assembly, wherein the first limit assembly is arranged on the lifting base plate 6, including a clamping plate 9 and a striker plate 10, wherein the two clamping plates 9 are arranged downwardly and relatively on the lower surface of the lifting base plate 6, and the striker plate 10 is horizontally clamped between the clamping plates 9 on both sides, and the second limit assembly is arranged on the fixed bracket 7, including a limit plate 11, the limit plate 11 is arranged horizontally and fixedly connected to the fixed bracket 7, the limit plate 11 is located between the striker plate 10 and the lifting base plate 6, and the limit plate 11 overlaps with the striker plate 10 in the vertical projection direction, that is, during the rising process of the lifting base plate 6 under the action of the cylinder 5, the striker plate 10 is driven by the clamping plates 9 on both sides and is blocked and stops moving upward after contacting the limit plate 11, and the lifting base plate 6 stops moving upward. By adjusting the distance of the striker plate 10 relative to the lifting base plate 6, that is, adjusting the position of the striker plate 10 at the clamping plates 9 on both sides, the lifting height of the lifting base plate 6 can be adjusted.

[0028] In some embodiments, Figure 5 and Figure 6As shown, the first limiting assembly includes a connecting plate 12 and a strike plate adjusting bolt 13. The connecting plate 12 is located below the strike plate 10 in the vertical direction and fixes the bottom ends of the clamping plates 9 on both sides. The connecting plate 12 can limit the maximum downward distance of the strike plate 10 relative to the lifting base plate 6. A threaded hole is provided on the connecting plate 12. The strike plate adjusting bolt 13 is screwed into the threaded hole in the vertical direction. The lower surface of the strike plate 10 abuts against the top of the strike plate adjusting bolt 13, that is, the top height of the strike plate adjusting bolt 13 limits the maximum distance of the strike plate 10 relative to the lifting base plate 6, that is, limits the maximum height of the lifting of the lifting base plate 6.

[0029] In some embodiments, Figure 5 and Figure 6 As shown, the second limiting member includes a limiting bolt 14, and the limiting plate 11 is provided with a threaded hole which passes through in the vertical direction. The limiting bolt 14 passes through the threaded hole of the limiting plate 11 vertically downward. At this time, the head end of the limiting bolt 14 is located between the limiting plate 11 and the impact plate 10, and the vertical projection of the limiting bolt 14 overlaps with the impact plate 10. When the impact plate 10 runs upward until it contacts the head end of the limiting bolt 14, the lifting base plate 6 is at the highest lifting distance. The maximum lifting height of the lifting base plate 6 can be further adjusted by adjusting the vertical height of the head end of the limiting bolt 14 relative to the limiting plate 11.

[0030] In some embodiments, Figure 5 and Figure 6 As shown, the second limiting member includes a buffer 15, the head end of the buffer 15 is downwardly arranged on the limiting plate 11, and the head end of the buffer 15 is arranged opposite to the impact plate 10. When the impact plate 10 moves upward by a certain preset distance, it will contact the head end of the buffer 15 and further compress the buffer 15. The buffer 15 buffers the impact plate 10 to the position of the limiting bolt 14, thereby preventing a hard collision during the lifting process, reducing noise, and improving the life of the device.

[0031] In some embodiments, Figure 5 and Figure 6 As shown, a pointer 16 is provided on the outer side of the impact plate 10, and the pointer 16 points to one side of the clamping plate 9. A scale 17 is provided on the clamping plate 9 on the side corresponding to the pointer 16. The scale 17 has a length scale and is pointed to by the pointer 16. When the height of the impact plate 10 is adjusted by the impact plate adjusting bolt 13, it will be quantified by the pointer 16 and the scale 17, and precise adjustment can be achieved.

[0032] In some embodiments, Figure 1 and Figure 3As shown, the lifting base plate 6 is provided with an avoidance portion 601 at a corresponding position in the vertical direction of the short roller 3, the lower end of the short roller support frame 18 is fixedly connected to the roller conveyor 1 through a bracket, and the upper end of the short roller support frame 18 passes through the avoidance portion 601 to support the end of the corresponding short roller 3 away from the edge of the roller conveyor 1 where the short roller 3 is located. Due to the provision of the avoidance portion 601, the lifting base plate 6 has a larger area and can be suitable for loads with a larger surface area.

[0033] In some embodiments, Figure 5 As shown, it includes a guiding mechanism, which can be a screw elevator 19. The transmission box 191 of the screw elevator 19 partially passes through the fixed bracket 7, the screw 192 is arranged in the vertical direction, and the lifting end of the screw 192 is connected to the jacking base plate 6. The use of the screw elevator as the guiding mechanism is more stable than the linear bearing guide, and can bear part of the load.

[0034] In some embodiments, Figures 1 to 3 As shown, upward positioning pins 20 and support columns 21 are provided above the lifting base plate 6. The positioning pins 20 play a positioning role for the load, and the support columns 21 play a supporting role for the load, so that the lifting process of the load is more firm and stable.

[0035] In some embodiments, Figure 1 As shown, a backstop 22 is provided in the middle section of the roller conveyor 1 near the feeding section, and a stopper 23 is provided in the middle section of the roller conveyor 1 near the discharging end. Both the backstop 22 and the stopper 23 are at least partially higher than the conveying plane.

[0036] The operation process of the present application is described below. When the load enters the roller conveyor 1 and is driven to run and stopped by the stopper 23, the check valve 22 prevents the load from rebounding. The load is located in the spacer 4, that is, above the lifting base plate 6. The lifting base plate 6 is in a low stroke position at this time. The lifting base plate 6 is displaced upward by the cylinder 5. At this time, the impact plate 10 is displaced upward at the same time. It is displaced to the position of the buffer 15 and is blocked by the head end position of the limit bolt 14. The lifting base plate 6 completes the maximum upward lifting stroke, and the load is lifted from the conveying plane to the processing position height. It should be noted that when the maximum lifting stroke needs to be adjusted, the impact plate adjustment bolt 13 is adjusted, and the scale 17 is referred to to complete the precise adjustment. When the load is processed, the lifting base plate 6 is lowered, the load returns to the conveying plane, the stopper 23 is in the release state, and the load continues to run.

[0037] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
