Description

Technical Field

[0001] The invention relates to the technical field of iron roller processing, in particular to automatic loading, unloading and replacing equipment for iron rollers. Background Art

[0002] Iron rollers are often used in devices for peeling or crushing the seeds of crops. Common ones include: iron roller energy-saving rice milling machine, iron roller peeling machine and a high-efficiency vertical iron roller rice milling machine for rice processing. The main function of the device is to drive the iron roller to rotate, and the iron roller is used to squeeze the crops.

[0003] The iron roller needs to be turned and polished during the production process. In the existing process, the two ends of the iron roller are clamped with a clamping claw, and then connected to the clamping claw through a suspension device to drive the iron roller to move. In order to improve work efficiency and reduce the physical labor of the staff and realize the automation of the device, most production lines are equipped with position sensors to detect the position of the device. When the iron roller is moved to the appropriate position, the staff operates the machine to perform relevant operations on the iron roller. At this time, PLC technology is used to realize automatic control of the mechanical device. However, when the existing device is processing, the iron roller is suspended by the suspension device throughout the process. Therefore, the existing device is not easy to position and needs to be fixed by personnel, which brings great inconvenience to the operation. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an automatic loading and unloading and replacing device for iron rollers.

[0008] As a further solution of the present invention: the clamping arm is star-shaped, and the height of the moving block is greater than the depth of the moving groove.

[0009] As a further solution of the present invention: a load-bearing row rod is welded to an outer wall of one side of the support frame of the second fixing claw, and a plurality of threaded holes distributed at equal distances are opened on the outer wall of the bottom plate where the second fixing claw is located.

[0010] As a further solution of the present invention: a plurality of guide grooves distributed at equal distances are formed on the top outer wall of the bottom plate, and the load-bearing row rods are in sliding contact with the inner walls of the guide grooves.

[0029] In the present invention, the first fixed clamping claw 3 and the second fixed clamping claw 8 are both composed of an electric telescopic rod 22, a connecting base 24, a lifting block 20 and a support frame 19. The electric telescopic rod 22 is fixed on the base plate 1, the connecting base 24 is fixed to the bottom of the electric telescopic rod 22, the lifting block 20 is fixedly installed on the top of the output end of the electric telescopic rod 22, and the support frame 19 is fixedly installed on the connecting base 24, and the support frame 19 is located on both sides of the electric telescopic rod 22; when the electric telescopic rod 22 is extended upward, the two clamping arms 17 rotate, and at this time, the two clamping blocks 16 are in an open state; when the electric telescopic rod 22 is retracted downward, the lifting block 20 moves downward with the moving block 18, and at the same time, the two moving blocks 18 move away from each other along the inner wall of the moving groove 21, and at this time, the clamping arm 17 rotates to make the clamping block 16 in a folded and clamped state, so that the clamping block 16 can clamp and release the iron roller body 7 through the action of the electric telescopic rod 22.

[0030] In the present invention, the upper part of the support frame 19 is rotatably connected to two symmetrically distributed clamping arms 17, and the upper ends of the clamping arms 17 are fixedly connected to the clamping blocks 16, and the bottom ends of the clamping arms 17 are hinged to the moving blocks 18. The top outer wall of the lifting block 20 is provided with a moving groove 21, and the moving blocks 18 are in sliding contact with the inner wall of the moving groove 21. The clamping arms 17 are star-shaped, and the height of the moving blocks 18 is greater than the depth of the moving groove 21, so as to facilitate the rotation between the moving blocks 18 and the clamping arms 17.

[0031] In the present invention, a load-bearing row rod 23 is fixedly connected to the outer wall of one side of the support frame 19 of the second fixed claw 8, a plurality of threaded holes equidistantly distributed are provided on the outer wall of the base plate 1 where the second fixed claw 8 is located, a plurality of guide grooves 15 equidistantly distributed are provided on the top outer wall of the base plate 1, and the load-bearing row rod 23 is in sliding contact with the inner wall of the guide groove 15, and the connecting base 24 on the second fixed claw 8 is adjusted to the installation position of the threaded hole, and the load-bearing row rod 23 is stretched outward from the guide groove 15, so that the slide rail 5 with the support plate 6 installed has a suitable support, thereby avoiding the phenomenon of insufficient support of the slide rail 5 where the support plate 6 is located when the fixed iron roller body 7 is processed.

[0032] In the present invention, the outside of the slide rail 5 near the second fixed claw 8 is fixedly connected with a support plate 6, and the top outer wall of the bottom plate 1 on the side where the support plate 6 is located is provided with a plurality of mounting holes 9, and the support plate 6 is fixed at the mounting holes 9 by bolts; by adjusting the installation position of the support plate 6 and the mounting holes 9, the spacing between the two slide rails 5 can be adjusted, and at this time, the stretching bearing plate 13 is automatically stretched to adapt to the spacing of the slide rails 5, thereby facilitating adaptation to iron roller bodies 7 of multiple length specifications.

[0033] In the present invention, the first position sensor 2 and the second position sensor 4 are fixedly installed on the top outer wall of the base plate 1, and the second position sensor 4 is located between the gearbox 12; when the stretching bearing plate 13 moves to the set first position sensor 2, the controller controls the power box 11 to start decelerating, and when the stretching bearing plate 13 moves to the second position sensor 4, the gearbox 12 stops rotating, thereby achieving a slow stop, which is beneficial to avoid the impact of sudden stop on the device.

[0034] In the present invention, grooves are provided at both ends of the tensile bearing plate 13, and buffer pads are provided on the inner walls of the grooves. The iron roller body 7 is located on the buffer pads, and lubricant is applied to the outer surface of the buffer pads.

[0035] Working principle and usage: The power device and the signal detection device are electrically connected to the PLC control cabinet. When the iron roller body 7 is placed on the stretching bearing plate 13, the pressure sensor detects the pressure change, thereby controlling the gearbox 12 to operate through the PLC control cabinet, and the power box 11 to operate, and the gearbox 12 drives the threaded rod 10 to rotate, thereby driving the stretching bearing plate 13 carrying the iron roller body 7 to move. When the stretching bearing plate 13 moves to the set first position sensor 2, the controller controls the power box 11 to start decelerating, and when the stretching bearing plate 13 moves to the second position sensor 4, the gearbox 12 stops. The electric telescopic rod 22 is in an extended state. When the electric telescopic rod 22 is retracted downward, the lifting block 20 moves downward with the moving block 18. At this time, the clamping arm 17 rotates to make the clamping block 16 in a folded and clamped state, thereby clamping and fixing the iron roller body 7; when the iron roller body 7 needs to be turned over, the electric telescopic rod 22 is appropriately extended upward so that the iron roller body 7 falls into the groove of the stretching bearing plate 13. Since the buffer pad is coated with lubricant, it is convenient for the staff to rotate the iron roller body 7. After the rotation is completed, the electric telescopic rod 22 is actuated, and the iron roller body 7 is clamped by the clamping block 16.
