Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Continuous cutting equipment as fig. 1 to 8, including the base that distributes in pairs, including left side base 1 and right side base 2, constitute the hand hay cutter between left side base 1 and the right side base 2 and cut the processing region, its distinctive and easy to understand lies in: in order to realize continuous feeding of materials to be processed, a driving roller 3 is installed in the chopping and cutting processing area, and one side of the driving roller 3, which is positioned on the base, is connected with a driving device. The chopping processing area is provided with a driven roller 4 at the upper end of the driving roller 3. Auxiliary driving devices are arranged on two sides of the driven roller 4 and are connected with the corresponding left base 1 and the right base 2. In combination with the actual use, the driven roller 4 is stressed by a pressing force under the action of the driven roller cylinder 20, so that the distance between the driven roller 4 and the driving roller 3 is reduced, and the materials can be clamped. Therefore, when the driving roller 3 rotates under the control of the driving device, the driven roller 4 can also realize appropriate follow-up rotation, and smooth feeding of materials is ensured. In the process of feeding the material, if the driven roller 4 is not used for performing corresponding matching movement, the driving roller 3 cannot smoothly feed the material under the control of the driving device, and an idle phenomenon often occurs. Consider the needs that cut in succession, the utility model discloses the discharge end department that is located drive roll 3 at the hand hay cutter cutting processing region is provided with the scissors device. Specifically, the scissors device comprises an upper scissors blade 5, and the front end of the upper scissors blade 5 is movably connected with a lower scissors blade 7 through a scissors end shaft 6. The scissors end shaft 6 is provided with an auxiliary spring for adjusting the pressing force at the joint of the front ends of the upper scissors blade 5 and the lower scissors blade 7, so as to adjust the opening and closing friction force of the scissors.

A guide plate 8 is provided at a position in close contact with the upper scissor piece 5 at the rear of the upper scissor piece 5, and a slit through which the material to be cut passes is provided in the guide plate 8. Therefore, the sheared material is conveyed to the position below the shearing mouth through the slit due to the existence of the slit, and the material can be prevented from falling off after being sheared. Furthermore, in consideration of the shearing control of the scissor device, the tail end of the upper scissor blade 5 is provided with an upper scissor shaft assembly, the tail end of the lower scissor blade 7 is provided with a lower scissor shaft assembly, and the upper scissor shaft assembly and the lower scissor shaft assembly are connected through a cylinder assembly 9.

In view of a preferred embodiment of the present invention, the upper scissor shaft assembly includes a cylinder block 10 connected to the left base 1. In order to facilitate the subsequent cylinder assembly 9 to drive the lower shear blade 7 to move smoothly, a cylinder rotating shaft 11 is arranged on the cylinder seat 10. And simultaneously, the utility model discloses be provided with cylinder bearing 12 at the front end of cylinder pivot 11, cylinder bearing 12 outer joint has cylinder mounting panel 13. Specifically, the cylinder mounting plate 13 is fixed to the front end of the cylinder rotating shaft 11 by being pressed by the cylinder bearing 12 and the lock nut 14, and can rotate around the cylinder rotating shaft 11. And, in order to realize smooth operation drive, the cylinder assembly 9 is installed on the cylinder mounting plate 13, so that the cylinder assembly 9 can rotate around the cylinder rotating shaft 11.

As further seen in connection with fig. 5, the lower scissor axle assembly includes a floating joint 15, a fixed end of the floating joint 15 being adapted to be coupled to the trailing end of the lower scissor blade 7, and a floating end of the floating joint 15 being coupled to an adjustment mechanism 16. The adjusting mechanism 16 is provided with a lower scissors seat 17, and the air cylinder assembly 9 is connected with the lower scissors seat 17.

As seen in connection with fig. 6 to 8, the lower scissor blade 7 is attached to the fixed end of the floating joint 15. Meanwhile, the adjusting mechanism 16 comprises an optical axis 23 used for being connected with the floating end of the floating joint 15, one end of the optical axis 23 is connected with the end sleeve 25, and the optical axis 23 can slide in an inner hole of the end sleeve 25 to form clearance fit with a clearance allowance of 0.05-0.1 mm. The optical axis 23 is sleeved with a spring 22, one side of the spring 22 abuts against one end face of the floating joint 15, and the other side of the spring 22 abuts against the side end face of the end sleeve 25. End sleeve 25 is connected into the internal threaded through hole of lower scissor seat 17 through outer ring threads 24. The locknut 18 is screwed onto the end sleeve 25. In addition, in view of the actual assembly, the optical axis 23 is connected to the floating joint 15 of the lower scissor shaft assembly.

In practice, with the broken line as a boundary line where blade deformation occurs, the floating joint 15 is subjected to a force to the left from the spring 22 in the adjustment mechanism 16, and is transmitted to the lower scissor blade 7. The lower blade 7 is thus subjected to a force to the left along the axis 21. The magnitude of this force can be adjusted by the adjustment mechanism 16. Under this controlled force, the lower shear blade 7, which is made of spring steel, will undergo a torsional deformation to the left, the amount of which is typically controlled to within 2 mm. After torsional deformation occurs, due to the fact that a deviation amount of +/-5 degrees is arranged between the floating end and the fixed end to which the floating joint 15 belongs, the fixed end and the floating end can have a non-coaxial phenomenon, so that improper stress generated by torsional deformation can be absorbed, and the stability of the whole scissors assembly is enhanced. If the above-described amount of deflection is not present, the torque of such abnormal torsional deformation is transmitted to the cylinder assembly, and the stability of the entire assembly is impaired. This allows the lower cutting blade 7 to be brought into contact with the cut of the upper cutting blade 5 at any time by controlled deformation of the lower cutting blade 7.

Further, by sliding the optical axis 23 in the inner bore of the end sleeve 25, the adjusting mechanism 16 can expand and contract itself in the direction of the axis 21, in addition to generating a pressure to the left, the amount of expansion and contraction being a maximum of about 4 mm. By means of the elastic stretching mode, the force of the adjusting mechanism 16 acting on the lower shear blade 7 is adjustable. Meanwhile, the outer ring threads 24 of the end sleeve 25 are in threaded fit with the inner hole threads of the lower scissor seat 17, the spring 22 can be compressed to increase pressure by rotating the end sleeve 25 clockwise, and the spring 22 can be released to reduce pressure by rotating the end sleeve 25 anticlockwise. And the distance that the end sleeve 25 is screwed in is controllable. The spring 22 generates a large elastic force as the distance to be screwed increases, and the amount of deformation of the lower blade 7 increases, and decreases as the distance to be screwed decreases. Finally, the existence of the locknut 18 can meet the requirement of double-thread locking after corresponding tightness adjustment.

Further, the utility model discloses a drive arrangement be servo motor 19, and servo motor 19 passes through the shaft coupling and links to each other with one side of drive roll 3. Meanwhile, the auxiliary driving means employed is a driven driving cylinder 20.

The working principle of the utility model is as follows:

the feeding is done by a servo motor 19. With the utility model discloses the major control system who cooperatees and use can signal messenger cylinder assembly 9 actions, and it is closed with last shear blade 5 to drive lower shear blade 7 to accomplish and tailor.

At each moment of cutting, the lower shear blade 7 is in a leftward bent state, so that each joint point of the lower shear blade 7 and the upper shear blade 5 is in a tight state without a gap in the continuous jointing process. Thus, reliable shearing of ultrathin materials is satisfied.

Specifically, when the lower blade 7 is fitted to the upper blade 5 in the upward direction, the lower blade 7 gradually changes from the bent state to the straightened state. At the same time, this deformation displacement is transmitted directly to the end of the lower blade 7 and further to the floating joint 15. In this case, if left untreated, this amount of deformation displacement is eventually transmitted to the cylinder assembly 9, so that the cylinder assembly 9 is subjected to a strong force in the non-self expansion and contraction direction, and the cylinder assembly 9 is damaged. Since the adjusting mechanism 16 can extend and contract, the displacement is absorbed by the adjusting mechanism 16 after passing through the floating joint 15, thereby ensuring the normal action of the cylinder assembly 9. Further, a gap can be secured between the lower blade 7 and the upper blade 5. Thus, the material is cut while being fed according to the adhesion of the lower shear blade 7 and the upper shear blade 5.
