[0024] The middle part of the material receiving table 30 is provided with a recess, and the recess is provided with a clamping assembly 70, the clamping assembly 70 comprising a support frame 71, the support frame 71 being provided with a hinge seat 72 at both ends, a pair of clamping plates 73 being hinged to the corresponding hinge seat 72, a guide hole 75 being provided on the support frame 71 corresponding to the lower end of each clamping plate 73, a piston 76 being provided in each guide hole 75, a ball pin 74 being provided on one end of each piston 76 near the clamping plate 73, the ball pin 74 being threadedly connected to the piston 76 on one end and being hinged to the lower end of the clamping plate 73 on the other end, the other end of each piston 76 being hinged to a connecting rod 77, a pneumatic cylinder 78 being provided on the material receiving table 30 below the center of the support frame 71, the piston rod of the pneumatic cylinder 78 penetrating the material receiving table 30, the end of the piston rod being hinged to a pair of connecting rods 77, the pneumatic cylinder 78 driving the piston rod to extend and retract, the piston rod driving the piston 76 to reciprocate through the connecting rod 77, the piston 76 driving a pair of clamping plates 73 to rotate around the hinge seat 72, realizing clamping and loosening of the aluminum bar.

[0025] A pressure sensor 90 is arranged at the center of the support frame 71. When the aluminum rod is placed on the pulley assembly 60 of the material receiving table 30, the aluminum rod presses the pressure sensor 90. The pressure sensor 90 is connected to the electromagnetic valve through a wire. The electromagnetic valve controls the extension and retraction of the pneumatic cylinder 78 to clamp the aluminum rod.

[0026] A position sensor 100 is arranged on the base 20 at one side of the peeling knife 40. The material receiving table triggers the position sensor 100. The position sensor 100 is connected to the electromagnetic valve through a wire. The electromagnetic valve controls the retraction of the pneumatic cylinder 78 to release the aluminum rod.

[0028] A return spring 80 is arranged at one end of the linear guide rail 50 close to the peeling knife 40. The return spring 80 is sleeved on the linear guide rail 50 to reset the material receiving table 30.

[0029] The working process of the aluminum rod peeling device is as follows. The aluminum rod is placed on the material receiving table 30. The two ends of the aluminum rod are placed on a pair of pulley assemblies 60 respectively. The pulleys 62 on the pulley assemblies 60 form a V-shaped support for the aluminum rod. The aluminum rod can move along the center axis. When the aluminum rod presses the pressure sensor 90, the pressure sensor 90 is connected to the electromagnetic valve through a wire. The electromagnetic valve controls the extension and retraction of the pneumatic cylinder 78 to clamp the aluminum rod on the pulley assembly 60. The aluminum rod is fixed on the material receiving table 30 at this time and cannot move along the center axis. At the same time, the hydraulic cylinder 10 is started. The piston cylinder of the hydraulic cylinder 10 pushes the material receiving seat to press the aluminum rod. Due to the action of the clamping assembly 70, the clamping force overcomes the friction force and the elastic force of the return spring 80. The material receiving table 30 and the aluminum rod move synchronously along the linear guide rail 50. The material receiving table 30 presses the return spring 80 to compress. When the aluminum rod enters the peeling knife 40, the material receiving table 30 triggers the position sensor 100. The position sensor 100 is connected to the electromagnetic valve through a wire. The electromagnetic valve controls the retraction of the pneumatic cylinder 78 to release the aluminum rod. At this time, the aluminum rod continues to enter the peeling knife 40 under the action of the hydraulic cylinder 10. The material receiving table 30 moves in the opposite direction with the aluminum rod under the action of the return spring 80 to reset. The aluminum rod moves in the opposite direction with the pulley assembly 60 by rolling friction. The device prevents the aluminum rod from jumping on the pulley assembly 60 due to the fixation of the clamping assembly 70 when the aluminum rod enters the peeling knife. This prevents the center axis from deviating from the axis of the peeling knife, making the peeling more uniform. At the same time, the degree of automation is higher.

[0030] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the protection scope of the present application.
