[0027] Generally, the initial position of the positioning roller of the sidewall positioning device 100 is lower than the upper surface of the down driving roller and the swing roller table 300. When the sidewall material passes through the swing roller table 300 to the rear conveyor, the swing roller table 300 swings down. Then the positioning roller of the sidewall positioning device 100 is raised to position the sidewall.

[0028] The sidewall positioning device 100 comprises a lifting mechanism 110 and an adjusting mechanism 120 coupled to the lifting mechanism 110.

[0029] The lifting mechanism 110 comprises a first lifting unit 110a and a second lifting unit 110b arranged opposite to each other and act synchronously.

[0030] It can be seen from Figure 3 that the first lifting unit 110a of the lifting mechanism 110 is a perspective view from a first direction, Figure 4 it can be seen that the first lifting unit 110a of the lifting mechanism 110 is a perspective view from a second direction, Figure 5 is a perspective view of the lifting mounting plate in the arbitrary lifting unit.

[0031] The structure of the first lifting unit 110a will be described below as an example, as shown in Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the first lifting unit 110a comprises a first sliding rail 111a, a first sliding block 112a, a first lifting mounting plate 113a, a first cylinder 114a, a first cylinder support 115a, a first one-way throttle valve 116a, a first screw bearing seat 117a, a first guide rod fixing seat 118a and a first positioning roller support 119a. The first sliding rail 111a is fixed to the downhill conveyor frame, and the first sliding block 112a is fitted on the sliding rail. The first cylinder support 115a is fixed to the first side of the frame of the sidewall positioning device, and the first cylinder 114a is vertically fixed to the first cylinder support 115a through the cylinder body. The cylinder rod of the first cylinder 115a is connected to the first lower mounting hole 1131a of the first lifting mounting plate 113a through a pin shaft, so as to be connected to the inner side of the first lifting mounting plate 113a, so that the lifting of the cylinder rod can drive the lifting mounting plate 113a to rise and fall. The outer side of the first lifting mounting plate 113a is fixed with the sliding block 112a. The first screw bearing seat 117a and the second screw bearing seat 117b are fixed at the positions of the first upper opening 1132a and the first lower opening 1133a arranged on the first lifting mounting plate 113a. The first guide rod fixing seat 118a is fixed above the first upper mounting hole 1134a. The first positioning roller support 119a is fixed above the first upper mounting hole 1134a of the first lifting mounting plate 113a.

[0032] The first lifting unit 110a and the second lifting unit 110b are respectively driven by the first cylinder 114a and the second cylinder 114b, guided by the first sliding rail and the second sliding rail, and can realize automatic material passing.

[0033] The first cylinder or the second cylinder adopts a one-way throttle valve 116 arranged on the cylinder, or an exhaust throttle valve, to adjust the lifting speed, so that the sidewall positioning device can quickly rise to the working position after the material passing. Each lifting unit can be guided by a sliding rail, so as to ensure that the sidewall positioning device stably rises and falls, and ensure that the angle of the adjusting roller is accurate and reliable.

[0034] For example, the first cylinder support and the first sliding rail of the first lifting unit are fixedly installed on the first side of the downhill conveyor frame. The second cylinder support and the second sliding rail of the second lifting unit are fixedly installed on the second side of the downhill conveyor frame. The initial position of the positioning roller of the sidewall positioning device should be lower than the upper surface of the downhill conveyor drive roller and the swing roller, so as to facilitate the material passing. At this time, the first cylinder and the second cylinder are in the retracted position. After the sidewall material passes through the swing roller, the cylinder rod of the first cylinder and the second cylinder is pushed out, and the adjusting mechanism 120 is pushed up to the working position.

The arrangement of the first screw rod and the second screw rod can be vertically up and down as shown in the figure, or horizontally front and back in other embodiments, or at an angle front and back or up and down. The first adjusting handle 125a is coupled to one end of the first screw rod, and the second adjusting handle 125b is coupled to one end of the second screw rod.

[0037] The first nut block 123a is a structure that spans the guide rod and the first screw rod 122a.

The second part of the first nut block 123a is hinged to the first end of the first connecting rod 126a, the second end of the first connecting rod 126a is hinged to the first end of the first T-shaped support rod 1271a of the first positioning roller 127a, and the second end of the first T-shaped support rod is pinned to the first positioning roller support 119a of its first lifting unit. Thus, rotating the first adjusting handle 125a can make the first screw rod rotate and drive the first nut block 123a to slide along the guide rod, thereby driving the first connecting rod to drive the first T-shaped support rod 1271a to pivot around the first positioning roller support 119a, and then drive the first positioning roller body 1272a of the first positioning roller 127a to rotate to the desired angle.

[0038] The second nut block 123b is arranged across the guide rod and the second screw rod 122b, the first part of the second nut block 123b is in threaded cooperation with the second screw rod 122b, and the second part of the second nut block 123b is in sliding cooperation with the guide rod. The second part of the second nut block 123b is hinged to the first end of the second connecting rod 126b, the second end of the second connecting rod 126b is hinged to the first end of the second T-shaped support rod 1271b of the second positioning roller 127b, and the second end of the second T-shaped support rod is pinned to the second positioning roller support 119b of the second lifting unit, so that rotating the second adjusting handle 125b can drive the second screw rod to rotate, thereby driving the second nut block 123b to slide along the guide rod, thereby driving the second connecting rod to drive the second T-shaped support rod 1271b to pivot around the second positioning roller support 119b, and thereby driving the second positioning roller body 1272b of the second positioning roller 127b to rotate to a desired angle with the horizontal plane. The correct positioning of the two sidewalls is realized.

[0039] The first adjusting handle and the second adjusting handle are hand wheels, and drive the two first screw rods and the second screw rod to rotate, respectively, and push the first nut block 123a or the second nut block 123b.

[0040] A first limiting ring 124a can also be arranged on the guide rod segment between the second part of the first nut block 123a and the first lifting unit, so as to limit the movement range of the first nut block 123a and adjust the maximum angle and the minimum angle of the swing of the first positioning roller. A second limiting ring 124b can also be arranged on the guide rod segment between the second part of the second nut block 123b and the second lifting unit, so as to limit the movement range of the second nut block 123b and adjust the maximum angle and the minimum angle of the swing of the second positioning roller.

[0041] The second part of the first nut block and the second part of the second nut block of the adjusting mechanism 120 adopt linear bearings for guidance, and the movement is flexible. The first screw rod and the second screw rod adjust the swing angles of the left and right rollers, respectively, and the two sidewalls are positioned separately, so that the positioning requirements under different conditions can be met. The mechanism formed by the connecting rods is connected firmly, and the swing angle range required by the sidewall positioning roller can be met.

[0042] The advantages of the embodiment of the utility model include:
