[0035] like Figure 3 As shown, the leveling device 1 includes a back plate 11, a front plate 12, a lifting device 13, a leveling component 14, and a movable seat 15. The back plate 11 is fixedly mounted on the frame 5 through a mounting column, and the front plate 12 is fixedly mounted on the back plate 11. The back plate 11 and the front plate 12 are spaced apart. The upper ends of the back plate 11 and the front plate 12 are tilted toward the direction close to the receiving component 3, so that the tension wheel 4 can be separated from the leveling device 1 by its own weight during the subsequent sorting process. The front plate 12 is provided with a sliding groove 121. The lifting device 13 includes a support plate 131 and a driving device 132. The driving device 132 can drive the support plate 13 1 slides along the sliding groove 121, the driving device 132 is an electric telescopic device, the front plate 12 is provided with a first mounting plate 122 and a second mounting plate 124, the first mounting plate 122 is located at the front end surface of the front plate 12, the second mounting plate 124 is located at the rear end surface of the front plate 12, the driving device 132 is fixedly mounted on the second mounting plate 124, the lower end of the telescopic rod of the driving device 132 is connected to the supporting plate 131, the lower end surface of the first mounting plate 122 is arranged parallel to the upper end surface of the supporting plate 131, so that the supporting plate 131 can make the detection error of the leveling end surface 421 smaller when driving the tensioning wheel 4 to approach the leveling assembly 14.

[0036] like Figure 4 , Figure 5 As shown, the leveling assembly 14 is installed on the first mounting plate 122, the leveling assembly 14 is located at the upper end of the sliding groove 121, the leveling assembly 14 includes three leveling terminals 141, the leveling assembly 14 includes a mounting seat 142, the mounting seat 142 is provided with three second mounting holes 1421, the mounting seat 142 is installed with three movable members 143, at least a portion of the movable member 143 extends out of the lower end surface of the mounting seat 142, at least a portion of the movable member 143 is located in the second mounting hole 1421, a first spring 144 is installed in the second mounting hole 1421, a leveling terminal 141 is installed at the upper end of each second mounting hole 1421, and the movable member 143 is installed in the second mounting hole 1421. The movable part 143 can move up and down along the first mounting hole 135. The lower end of the leveling terminal 141 is provided with a detection end 1411. The upper end of the movable part 143 can be close to or away from the detection end 1411. When the leveling end surface 421 contacts the lower end of the movable part 143, the movable part 143 is pressed by the leveling end surface 421 and moves upward until the upper end of the movable part 143 contacts the detection end 1411 of the leveling terminal 141. The control system connected to the leveling terminal 141 can receive signals and process them to obtain the time difference between the three leveling terminals 141 and the movable part 143, thereby determining whether the detected leveling end surface 421 is qualified.

[0037] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the front plate 12 is provided with a slide rail 123, and the slide rail 123 is located on the side of the sliding groove 121 close to the receiving component 3. The movable seat 15 is slidably installed on the slide rail 123, the support plate 131 is provided with a first side plate 133, and the movable seat 15 is provided with a second side plate 151. At least a part of the first side plate 133 is located below the second side plate 151. The first side plate 133 can drive the second side plate 151 to move, and the support plate 131 can drive the movable seat 15 to move. When the support plate 131 moves toward the leveling component 14, the first side plate 133 presses against the second side plate 151 and can drive the movable seat 15 to move upward. When the support plate 131 moves away from the leveling component 14, the movable seat 15 moves downward under the influence of gravity. The movable seat 15 can place the tensioning wheel 4, and the leveling end surface 421 is located within the range of the extension plate 42. The support plate 131 is used to support the extension plate 42.

[0038] like Figure 4 , Figure 6As shown, the lifting device 13 includes a limit member 18, which is installed on the support plate 131. The support plate 131 is provided with a first through hole 134 and a first mounting hole 135. The limit member 18 includes a mounting tube 181 and a limit column 182. The mounting tube 181 passes through the first through hole 134, and the limit column 182 passes through the first mounting hole 135. A third spring 1822 is installed in the first mounting hole 135. The limit column 182 is provided with a ring plate 1821, and the ring plate 1821 is located in the first mounting hole 135. The upper end of the third spring 1822 abuts against the lower end surface of the ring plate 1821. The extension plate 42 is provided with a second through hole 422. The first through hole 134 is aligned with the second through hole 422. When the support plate 131 is in the first position, at least a portion of the mounting tube 181 The mounting tube 181 is located in the second through hole 422. When the support plate 131 is in the second position, the mounting tube 181 leaves the second through hole 422. When the tensioning wheel 4 is placed on the movable seat 15, the lower end surface of the extension plate 42 is not in contact with the upper end surface of the support plate 131. The mounting tube 181 passes through the second through hole 422 to position the extension plate 42. When the driving device 132 drives the support plate 131 to move upward, when the first side plate 133 abuts against the second side plate 151, a gap is generated between the lower end surface of the main body 41 of the tensioning wheel 4 and the placement plane of the movable seat 15 on which the tensioning wheel 4 is placed. This can eliminate the error caused by the contact between the lower end surface of the main body 41 of the tensioning wheel 4 and the movable seat 15, and reduce the impact on the detection of the leveling end surface 421, making the leveling result more accurate.

[0039] More preferably, the movable seat 15 is provided with a stopper 152, which is located on the side of the movable seat 15 close to the support plate 131. The stopper 152 is provided with a stop surface 153, and the stop surface 153 is arc-shaped. The stop surface 153 abuts against the outer wall of the main body 41. The stop surface 153 of the movable seat 15 supports the main body 41, thereby playing a role in placing, positioning and limiting the tensioning wheel 4.

[0040] like Figure 4 , Figure 5 , Figure 6 As shown, a second spring 1811 is installed in the mounting tube 181, and a ball 1812 is installed in the mounting tube 181. The upper end of the second spring 1811 abuts against the ball 1812, and at least a portion of the ball 1812 is located in the mounting tube 181. The ball 1812 can move up and down along the mounting tube 181. When the leveling end surface 421 abuts against the movable part 143 and contacts the leveling assembly 14 for leveling calculation, the limiting column 182 abuts against the lower end surface of the first mounting plate 122, and the mounting tube 181 leaves the second through hole 422. Since the entire leveling device 1 is in an inclined state, the ball 1812 partially located in the second through hole 422 can play a certain limiting role on the extension plate 42, and can cooperate with the elastic force of the movable part 143 to clamp it, so as to prevent the tensioning wheel 4 from accidentally detaching during leveling.

[0041] like Figure 7 , Figure 8 , Fig. 9 As shown, the support plate 131 includes a first position, a second position, and a third position. When the support plate 131 is in the first position, the tensioning wheel 4 can be loaded and placed on the movable seat 15 and the support plate 131. At this time, the support plate 131 is in the initial position. The tensioning wheel 4 is positioned and placed on the movable seat 15 and the support plate 131. The driving device 132 drives the support plate 131 to move to the second position. When the support plate 131 is in the second position, the leveling end surface 421 contacts the movable member 143, and the movable member 143 is pressed upward to contact the detection end 1411 of the leveling terminal 141.

When the support plate 131 is in the second position, the push plate 161 can push the extension plate 42 out of the support plate 131. When the leveling terminal 141 is connected and the control system determines that the leveling end surface 421 is qualified, the cylinder 16 controls the push plate 161 to extend, and the push plate 161 pushes the extension plate 42 toward the movable seat 15, so that the extension plate 42 leaves the support plate 131. The qualified tensioning wheel 4 falls into the first receiving groove 32 of the receiving component 3 under the action of gravity.

[0042] The front plate 12 is installed with a base plate 17, and the base plate 17 is located at the lower end of the slide rail 123. A push rod 171 is provided on the upper end surface of the base plate 17. When the support plate 131 is in the first position and the third position, the upper end of the push rod 171 abuts against the lower end surface of the movable seat 15. When the leveling terminal 141 is connected, when the control system determines that the leveling end surface 421 is unqualified, the driving device 132 drives the support plate 131 to move from the second position to the third position, the push rod 171 abuts against the movable seat 15, and the first side plate 133 is separated from the second side plate 151. At this time, the second mounting tube 181 leaves the second through hole 422, and the tensioning wheel 4 slides toward the second receiving groove 33 of the receiving component 3 under the action of gravity, and the main body 41 leaves the movable seat 15. The unqualified tensioning wheel 4 can enter the second receiving groove 33, thereby forming a classification function for the tensioning wheel 4 after detection.
