The utility model has the advantages that: the pneumatic device is adopted to replace the original torsion spring to provide the torsion of the cutter shaft, so that the reliability of the torsion of the cutter shaft of the cutting machine is greatly improved, and the hidden danger of product quality caused by the breakage of the original torsion spring is avoided; due to the structural characteristics of the pneumatic device, the change of the torque of the cutter shaft is more flexible and convenient, the torque adjustment can be continuous, and the precision is higher.
Description
Technical Field
The utility model relates to the field of machinary, specifically a textile machinery, more specifically the turned angle regulation structure of cutter says so.
Background
The cutter is special equipment for a cellulose short fiber production line and is used for cutting cellulose fiber tows. For the butt of guaranteeing cutter blade and mill, the arbor of traditional cutter sets up torsion spring, and torsion relies on torsion spring to realize, and in the use, torsion spring appears the fracture easily, can not in time discover in production, causes the product to fall etc. because of cutting off the quality.
In addition, the adjustment of the torsion of the conventional cutter spring changes the torque and the torsion angle by adjusting the position of the spring, so that the precision is not high.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing a pneumatic adjustment structure can adjust the angle of torsion according to the elongation of cylinder, and concrete technical scheme is as follows:
a grinding disc is arranged on a rack, a cutter holder is arranged below the grinding disc, the cutter holder is arranged on the cutter holder, the cutting edge of a cutter is abutted against the grinding disc, a support is arranged on the rack, a rotary seat is arranged above the support and is in shaft connection with one end of a rocker, and the other end of the rocker is connected with the end part of a piston rod of an air cylinder; the middle position of the rocker is provided with a connecting plate, the connecting plate is in shaft connection with the hook, the lower part of the hook is fixed with the upper end of the sliding shaft, the lower part of the sliding shaft is fixed with the connecting plate, the two ends of the connecting plate are sleeved on the fulcrum shaft, the fulcrum shaft below the connecting plate is sleeved with a spring, the lower part of the fulcrum shaft is in shaft connection with a slotted hole of the swing rod, and the swing rod is fixed with the rotating shaft of the tool apron.
The sliding shaft is arranged in a sliding sleeve, and the sliding sleeve is fixed on the support.
The connecting plate is cross-shaped, 4 support shafts are arranged, each support shaft is in shaft connection with a slotted hole of a swing rod, and each swing rod is fixed with a tool apron rotating shaft.
The utility model has the advantages that: the pneumatic device is adopted to replace the original torsion spring to provide the torsion of the cutter shaft, so that the reliability of the torsion of the cutter shaft of the cutting machine is greatly improved, and the hidden danger of product quality caused by the breakage of the original torsion spring is avoided; due to the structural characteristics of the pneumatic device, the change of the torque of the cutter shaft is more flexible and convenient, the torque adjustment can be continuous, and the precision is higher.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a left side view of FIG. 1;
fig. 3 is a partially enlarged view of the lower end of the slide shaft.
Detailed Description
The utility model is described in detail with the attached drawings, as shown in the figure, a grinding disc 3 and a grinding disc motor 2 are arranged on a frame 1, and the grinding disc motor drives the grinding disc to rotate; a cutter seat 4 is arranged below the grinding disc, a cutter handle is arranged on the cutter seat 4, the cutting edge of the cutter is abutted against the grinding disc 3, a support 5 is arranged on the rack, a rotary seat 6 is arranged above the support 5, the rotary seat 6 is in shaft connection with one end of a rocker 7, and the other end of the rocker 7 is connected with the end part of a piston rod of the air cylinder 10; the middle position of the rocker is provided with a connecting plate 8, the connecting plate 8 is in shaft connection with a hook 9, the lower part of the hook 9 is fixed with the upper end of a sliding shaft 11, the lower part of the sliding shaft 11 is fixed with a connecting plate 13, two ends of the connecting plate 13 are sleeved on a support shaft 14, a spring 19 is sleeved on the support shaft 14 below the connecting plate 13, the lower part of the support shaft 14 is in shaft connection with a groove hole 17 of a swing rod 15, and the swing rod 15 is fixed with a tool apron rotating shaft 16. The structure ensures that the swing rod swings along with the up-and-down movement of the sliding shaft, and then the tool apron rotating shaft is driven to rotate.
In order to ensure the precision, the sliding shaft is arranged in a sliding sleeve 12 which is fixed on the support 5.
The connecting plate 13 is cross-shaped, the middle position of the connecting plate is connected with the sliding shaft, 4 end parts of the connecting plate are respectively sleeved on 4 fulcrum shafts, each fulcrum shaft is connected with a slotted hole of a swing rod in a shaft mode, and each swing rod is fixed with a tool apron rotating shaft.
One optimized structure is: the lower end of the support shaft 14 is fixed to a bushing 18, and the bushing 18 is coupled to the slot 17. This structure accessible axle sleeve's effect carries out the axial to the spring lower extreme spacing.
