Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, in particular to a cold-rolled steel plate receiving machine. Background Art

[0002] The coiled material of cold-rolled steel plate is cut into required lengths after unwinding, and after cutting, the cold-rolled steel plates need to be received, neatly stacked and packed. The Chinese utility model patent with the publication number of CN217512544U in the prior art proposes a cold-rolled steel plate receiving machine. Through the setting of the supporting device, when in use, the moving plate is moved to the highest position. When the first steel plate moves to the top surface of the moving plate, the moving plate moves downward, so that the top layer of the steel plate is flush with the top surface of the receiving box, which is convenient for collecting the next steel plate. This movement process is cycled until the receiving box is full of steel plates. When the steel plate passes under the conveying roller, the rotation of the conveying roller can assist the steel plate to enter the receiving box, reducing the situation where the steel plate cannot enter the receiving box.

[0003] However, in the above prior art, the conveying roller rotates to assist the steel plate to slide into the receiving box through the connecting table. Since the driving stroke of the conveying roller for the steel plate is limited, and the lower end of the connecting table is connected to the front end of the receiving box, when the steel plate detaches from the conveying table and the conveying roller, the rear end of the steel plate cannot directly fall into the receiving box. The rear end of the steel plate can only slide along the inclined connecting table for the entire length of the steel plate before entering the receiving box, resulting in a long sliding distance when receiving the steel plate and causing the steel plate not to be received in place. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a cold-rolled steel plate receiving machine that can guide the steel plate to the rear end of the receiving table, shorten the sliding distance when receiving the steel plate, enable the steel plate to be received in place, and has high receiving efficiency.

[0005] A cold-rolled steel sheet collecting machine of the utility model includes a frame and a plurality of conveying rollers, and the plurality of conveying rollers are rotatably installed on the frame; it further includes a shaft tube, a supporting roller, a first bearing seat, a bracket, a shaft rod, a pushing block, a push rod and a push rod assembly. The shaft tube is rotatably installed at the rear end of the frame, and a plurality of supporting rollers are arranged on the outer wall of the shaft tube. The shaft tube is driven by a driving assembly. The inner ring of the first bearing seat is sleeved on the outer wall of the shaft tube between the plurality of supporting rollers. The middle part of the bracket is connected to the outer ring of the first bearing seat, and the rear end of the bracket extends out of the rear end of the frame. The shaft rod is rotatably installed in the shaft tube. A plurality of chutes arranged along the axis of the shaft tube are arranged on the shaft tube between the plurality of supporting rollers. The pushing block is installed on the outer wall of the shaft rod, and the pushing block is slidably arranged in the chute of the shaft tube. The push rod is installed on the outer ring of the first bearing seat, and the push rod is aligned with the pushing block. The push rod assembly is used to adjust the position of the shaft rod in the shaft tube so that the shaft rod drives the pushing block to contact or disengage from the push rod; the plurality of conveying rollers and the supporting rollers rotatably support the steel sheet and convey it to the rear end of the frame. When the steel sheet reaches above the bracket, the push rod assembly drives the shaft rod to move in the shaft tube, so that the shaft rod drives the pushing block to move in the chute of the shaft tube, so that the pushing block is aligned with the side surface of the push rod. The shaft tube continues to rotate, driving the pushing block to rotate. The pushing block pushes the outer ring of the first bearing seat to rotate through the push rod, driving the front end of the bracket to turn up vertically, and turning the rear end of the bracket downward, so that the rear end of the bracket extends into the middle of an externally connected receiving table, and the rear end of the bracket points to the rear end of the receiving table. At this time, the bracket lifts the steel sheet from the plurality of conveying rollers and the plurality of supporting rollers, and makes the steel sheet slide down along the bracket, so that the rear end of the steel sheet directly falls on the rear end of the receiving table. After the steel sheet slides off the bracket, it is naturally flattened on the receiving table. The push rod assembly drives the shaft rod to reset, so that the shaft rod drives the pushing block to disengage from the push rod, so that the bracket resets. Compared with the prior art, it can guide the steel sheet to the rear end of the receiving table, align the end of the steel sheet with the end of the receiving table, and directly stack the steel sheet neatly on the receiving table, shortening the sliding distance when collecting the steel sheet, making the steel sheet collection in place and having high collection efficiency.

[0006] Preferably, it further includes an arm plate and a spring. The upper end of the arm plate is connected to the outer ring of the first bearing seat. One end of the spring is connected to the lower end of the arm plate, and the other end of the spring is connected to the frame; the elastic force of the spring makes the outer ring of the first bearing seat drive the front end of the bracket to be placed flat between the plurality of supporting rollers through the arm plate. After the pushing block and the push rod are disengaged, the bracket can automatically reset under the action of the elastic force of the spring, and the practicability is good.

[0007] Preferably, it further includes a plurality of rollers, and a plurality of rollers are rotatably installed on the bracket; the plurality of rollers rotatably support the steel sheet on the bracket, reducing the friction between the steel sheet and the bracket and improving the smoothness of the steel sheet sliding out.

[0008] Preferably, it further includes a driving motor, a driving wheel, a driven wheel and a transmission belt. The driving motor is installed on the frame. The output shaft of the driving motor is concentrically installed with the driving wheel. The driven wheel is concentrically installed on the shaft tube. The transmission belt is sleeved on the driving wheel and the driven wheel. The driving motor drives the driving wheel to rotate. The driving wheel drives the driven wheel to rotate through the transmission belt. The driven wheel drives the shaft tube to rotate, so as to drive the shaft tube and multiple idler rollers, and can also drive multiple conveying rollers to realize the conveying of the steel plate.

[0009] Preferably, the push rod assembly includes a cam, a second roller and a second spring. The cam is concentrically installed at one end of the shaft rod. The inner end face of the cam is stepped. The second roller is installed on the frame through a bracket. The second roller is in rolling contact with the inner end face of the cam. One end of the second spring is connected to the other end of the shaft rod, and the other end of the second spring is connected to the shaft tube. The elastic force of the second spring pulls the shaft rod towards one end of the shaft tube, so that the inner end face of the cam is always in rolling contact with the second roller. When the second roller reaches the convex part of the cam, it pushes the shaft rod outwards, so that the shaft rod drives the push block to slide in the shaft tube, thereby adjusting the relative position between the push block and the push rod. The structure is simple and can realize the receiving action with a fixed rhythm.

[0010] Preferably, the push rod assembly includes a push cylinder and a second bearing seat. The fixed end of the push cylinder is installed on the frame. The piston rod of the push cylinder is connected to the outer ring of the second bearing seat. The inner ring of the second bearing seat is sleeved and connected with the shaft rod. When the piston rod of the push cylinder extends, it pulls the shaft rod outwards of the shaft tube through the second bearing seat. When the piston rod of the push cylinder contracts, it pushes the shaft rod inwards of the shaft tube through the second bearing seat, so as to realize the relative movement between the shaft rod and the shaft tube, make the push block contact or separate from the push rod, and the control is more flexible and the practicability is good.

[0011] Preferably, it further includes a sliding table, a rack, a gear and a semi-gear ring. The sliding table is slidably installed at the rear end of the frame. The sliding table is used to carry the receiving table. The rack is installed on the sliding table. The gear is rotatably installed on the frame. The gear meshes with the rack. The semi-gear ring is installed on the arm plate. The semi-gear ring meshes with the gear. When the bracket is turned over and erected for receiving materials, the outer ring of the first bearing seat drives the arm plate to swing forward. The arm plate drives the semi-gear ring to rotate. The semi-gear ring meshes and drives the gear to rotate. The gear meshes with the rack and drives the sliding table to move backward. After the rear end of the steel plate is placed on the rear end of the receiving table, the sliding table drives the receiving table to move backward, so that the steel plate is separated from the bracket faster and the receiving efficiency is improved.

[0012] The beneficial effects of the present utility model compared with the prior art are as follows: Multiple conveying rollers and supporting rollers rotate to support the steel plate and convey it to the rear end of the frame. When the steel plate reaches above the bracket, the push rod assembly drives the shaft rod to move in the shaft tube, causing the shaft rod to drive the push block to move in the chute of the shaft tube, aligning the push block with the side surface of the push rod. The shaft tube continues to rotate, driving the push block to rotate. The push block pushes the outer ring of the first bearing seat to rotate through the push rod, driving the front end of the bracket to turn upwards and the rear end of the bracket to turn downwards, so that the rear end of the bracket extends into the middle of the externally connected receiving table and the rear end of the bracket points to the rear end of the receiving table. At this time, the bracket lifts the steel plate from the multiple conveying rollers and multiple supporting rollers, and the steel plate slides down along the bracket, making the rear end of the steel plate directly fall on the rear end of the receiving table. After the steel plate slides off the bracket, it lies flat on the receiving table naturally. The push rod assembly drives the shaft rod to reset, causing the shaft rod to drive the push block to disengage from the push rod, and the bracket resets.

The shaft tube 3 is rotatably installed at the rear end of the frame 1. A plurality of supporting rollers 4 are arranged on the outer wall of the shaft tube 3. The shaft tube 3 is driven by a driving assembly. The inner ring of the first bearing seat 5 is sleeved on the outer wall of the shaft tube 3 between the plurality of supporting rollers 4. The middle part of the bracket 6 is connected to the outer ring of the first bearing seat 5. The rear end of the bracket 6 extends out of the rear end of the frame 1. The shaft rod 7 is rotatably installed in the shaft tube 3. A plurality of chutes arranged along the axis of the shaft tube 3 are arranged on the shaft tube 3 between the plurality of supporting rollers 4. The pushing block 8 is installed on the outer wall of the shaft rod 7. The pushing block 8 is slidably arranged in the chute of the shaft tube 3. The push rod 9 is installed on the outer ring of the first bearing seat 5. The push rod 9 is aligned with the pushing block 8. The push rod assembly is used to adjust the position of the shaft rod 7 in the shaft tube 3 so that the shaft rod 7 drives the pushing block 8 to contact or separate from the push rod 9. It also includes an arm plate 10 and a spring 11. The upper end of the arm plate 10 is connected to the outer ring of the first bearing seat 5. One end of the spring 11 is connected to the lower end of the arm plate 10. The other end of the spring 11 is connected to the frame 1. It also includes a plurality of rollers 12. A plurality of rollers 12 are rotatably installed on the bracket 6. It also includes a driving motor 13, a driving wheel 14, a driven wheel 15 and a transmission belt 16. The driving motor 13 is installed on the frame 1. The output shaft of the driving motor 13 is concentrically installed with the driving wheel 14. The driven wheel 15 is concentrically installed on the shaft tube 3. The transmission belt 16 is sleeved on the driving wheel 14 and the driven wheel 15. The push rod assembly includes a cam 17, a second roller 18 and a second spring 19. The cam 17 is concentrically installed at one end of the shaft rod 7. The inner end face of the cam 17 is stepped. The second roller 18 is installed on the frame 1 through a bracket. The second roller 18 is in rolling contact with the inner end face of the cam 17. One end of the second spring 19 is connected to the other end of the shaft rod 7. The other end of the second spring 19 is connected to the shaft tube 3.

[0024] The drive motor 13 drives the driving wheel 14 to rotate. The driving wheel 14 drives the driven wheel 15 to rotate through the transmission belt 16. The driven wheel 15 drives the shaft tube 3 to rotate, realizing the drive of the shaft tube 3 and multiple idler rollers 4, and can also drive multiple conveying rollers 2 to realize the conveying of the steel plate. The multiple conveying rollers 2 and idler rollers 4 rotate to support the steel plate and convey it to the rear end of the frame 1. The elastic force of the spring 11 makes the outer ring of the bearing block one 5 drive the front end of the bracket 6 to be placed flat between the multiple idler rollers 4 through the arm plate 10. When the steel plate reaches above the bracket 6, the elastic force of the spring two 19 pulls the shaft rod 7 towards one end of the shaft tube 3, so that the inner end surface of the cam 17 is always in rolling contact with the roller two 18. When the roller two 18 reaches the convex part of the cam 17 towards the inside, it pushes the shaft rod 7 outwards, so that the shaft rod 7 drives the push block 8 to slide in the shaft tube 3, thereby adjusting the relative position between the push block 8 and the push rod 9, making the shaft rod 7 drive the push block 8 to move in the chute of the shaft tube 3, so that the push block 8 is aligned with the side surface of the push rod 9. The shaft tube 3 continues to rotate, driving the push block 8 to rotate. The push block 8 drives the outer ring of the bearing block one 5 to rotate through the push rod 9, driving the front end of the bracket 6 to turn upwards and stand up, and making the rear end of the bracket 6 turn downwards, so that the rear end of the bracket 6 extends into the middle of the externally connected receiving table, and the rear end of the bracket 6 points to the rear end of the receiving table. At this time, the bracket 6 lifts the steel plate from the multiple conveying rollers 2 and multiple idler rollers 4, and makes the steel plate slide down along the bracket 6. The multiple rollers 12 rotate to support the steel plate on the bracket 6, reducing the friction between the steel plate and the bracket 6, improving the smoothness of the steel plate sliding out, so that the rear end of the steel plate directly falls on the rear end of the receiving table. After the steel plate slides off the bracket 6, it is naturally placed flat on the receiving table. The push rod assembly drives the shaft rod 7 to reset, so that the shaft rod 7 drives the push block 8 to disengage from the push rod 9. After the push block 8 and the push rod 9 disengage, the bracket 6 automatically resets under the elastic force of the spring 11. Compared with the prior art, it can guide the steel plate to the rear end of the receiving table, align the end of the steel plate with the end of the receiving table, and directly stack the steel plate neatly on the receiving table, shortening the sliding distance of the steel plate during receiving, making the steel plate receiving in place, and having high receiving efficiency.

[0025] Embodiment 2

[0026] As Figure 2 and Figure 5 shown, on the basis of Embodiment 1, the push rod assembly includes a push cylinder 20 and a bearing block two 21. The fixed end of the push cylinder 20 is installed on the frame 1, the piston rod of the push cylinder 20 is connected to the outer ring of the bearing block two 21, and the inner ring of the bearing block two 21 is sleeved and connected to the shaft rod 7.

[0027] When the piston rod of the push cylinder 20 extends, it pulls the shaft rod 7 towards the outside of the shaft tube 3 through the bearing block two 21. When the piston rod of the push cylinder 20 contracts, it pushes the shaft rod 7 towards the inside of the shaft tube 3 through the bearing block two 21, thereby realizing the relative movement between the shaft rod 7 and the shaft tube 3, making the push block 8 contact or disengage from the push rod 9, and the control is more flexible.

[0028] Embodiment 3

[0029] As Figures 1 to 3 and Figure 7 shown, on the basis of Embodiment 1 or 2, it further includes a sliding table 22, a rack 23, a gear 24 and a semi-tooth ring 25. The sliding table 22 is slidably installed at the rear end of the frame 1. The sliding table 22 is used to carry the receiving table. The rack 23 is installed on the sliding table 22. The gear 24 is rotatably installed on the frame 1. The gear 24 meshes with the rack 23. The semi-tooth ring 25 is installed on the arm plate 10. The semi-tooth ring 25 meshes with the gear 24.

[0030] When the bracket 6 is turned over and erected for material collection, the outer ring of the bearing seat 1-5 drives the arm plate 10 to swing forward. The arm plate 10 drives the semi-tooth ring 25 to rotate. The semi-tooth ring 25 meshes and drives the gear 24 to rotate. The gear 24 meshes with the rack 23 to drive the sliding table 22 to move backward. After the rear end of the steel plate is placed on the rear end of the receiving table, the sliding table 22 drives the receiving table to move backward, so that the steel plate is separated from the bracket 6 faster, improving the material collection efficiency.

[0031] As Figures 1 to 7 shown, for a cold-rolled steel plate receiving machine of the present utility model, when it works, first, a plurality of conveying rollers 2 and supporting rollers 4 rotate to support the steel plate and convey it to the rear end of the frame 1. When the steel plate reaches above the bracket 6, the push rod assembly drives the shaft rod 7 to move in the shaft tube 3, so that the shaft rod 7 drives the push block 8 to move in the chute of the shaft tube 3, making the push block 8 align with the side surface of the push rod 9. Then the shaft tube 3 continues to rotate, driving the push block 8 to rotate. The push block 8 pushes the outer ring of the bearing seat 1-5 to rotate through the push rod 9, driving the front end of the bracket 6 to turn up and erect, and the rear end of the bracket 6 to turn down. Then the rear end of the bracket 6 extends into the middle of an externally connected receiving table, and the rear end of the bracket 6 points to the rear end of the receiving table. At this time, the bracket 6 lifts the steel plate from the plurality of conveying rollers 2 and the plurality of supporting rollers 4, and the steel plate slides down along the bracket 6, so that the rear end of the steel plate directly falls on the rear end of the receiving table. When the bracket 6 is turned over and erected for material collection, the outer ring of the bearing seat 1-5 drives the arm plate 10 to swing forward. The arm plate 10 drives the semi-tooth ring 25 to rotate. The semi-tooth ring 25 meshes and drives the gear 24 to rotate. The gear 24 meshes with the rack 23 to drive the sliding table 22 to move backward. After the rear end of the steel plate is placed on the rear end of the receiving table, the sliding table 22 drives the receiving table to move backward, so that the steel plate is separated from the bracket 6 faster. Finally, after the steel plate slides off the bracket 6, it is naturally placed flat on the receiving table. The push rod assembly drives the shaft rod 7 to reset, so that the shaft rod 7 drives the push block 8 to disengage from the push rod 9, and the elastic force of the spring 11 makes the bracket 6 reset.
