DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] Embodiment one

[0037] Please refer to Figures 1-12 The present application provides a bearing steel mesh belt type recrystallization annealing furnace, which comprises a feeding machine 1 and an annealing furnace body 2. The feeding machine 1 comprises a fixed frame 3, a feeding roller shaft 4 driven by a power element on the fixed frame 3, and a conveying chain 23 driven by the power element to drive transmission, so that the feeding roller shaft 4 rotates at the original position (the feeding roller shaft 4 is a conventional technology), and the workpiece located on the feeding roller shaft 4 is moved to make the workpiece enter the annealing furnace body 2 for processing.

[0038] The feeding machine 1 is further provided with a movable column 5 and a movable element. The movable element is used to make the movable column 5 move the workpiece located on the feeding roller shaft 4. In the process of rotating the feeding roller shaft 4 to move the workpiece, the movable element is also moved, so that the movable column 5 located on the feeding roller shaft 4 moves along the conveying direction of the feeding machine 1 at a certain angle to make reciprocating circular motion, so as to move the workpiece located on the feeding roller shaft 4 into the annealing furnace body 2.

[0039] In the vertical direction, the movable column 5 also moves up and down reciprocally, so that when the movable column 5 moves circularly towards the annealing furnace body 2, the movable column 5 moves vertically downward, thereby facilitating the workpiece on the feeding roller shaft 4 to enter the feeding port 22 of the annealing furnace body 2. When the movable column 5 moves circularly away from the annealing furnace body 2, the movable column 5 moves vertically upward, thereby avoiding the movable column 5 from moving the workpiece on the feeding roller shaft 4 away from the annealing furnace body 2.

[0040] The movable part comprises a rotating disc 6, the edge of which is rollingly connected with a movable plate 7, the end of which is connected with one of the feeding roller shafts 4, the middle shaft of the rotating disc 6 is rotationally connected with a limiting plate 8, the end of the limiting plate 8 is rotationally connected with a pressing column 9 which rollingly connects with the movable plate 7.

[0041] The movable part further comprises a connecting plate 15 which is fixedly connected with the end of one of the feeding roller shafts 4, the other end of the connecting plate 15 is rotationally connected with the movable plate 7, and the rotating disc 6 is rotationally connected with the fixed frame 3.

[0042] The feeding roller shaft 4 rotates at the original position on the fixed frame 3, drives the connecting plate 15 to rotate, and the end of the connecting plate 15 makes a circular motion, so that one end of the movable plate 7 makes a circular motion, wherein the movable plate 7 is located between the pressing column 9 and the rotating disc 6, and since the rotating disc 6 rotates at the original position on the fixed frame 3, the limiting plate 8 rotates, and the limiting plate 8 drives the pressing column 9 to make a circular motion at a certain angle (the circular motion of the pressing column 9 is taken as the axis of the rotating disc 6), under the limitation of the pressing column 9 and the rotating disc 6, the movable plate 7 relatively slides along the rotating disc 6 and the pressing column 9, and the other end of the movable plate 7 makes a small distance reciprocating movement, so that the whole movable plate 7 relatively reciprocating rotates at a small angle with respect to the fixed frame 3.

[0043] That is, the feeding roller shaft 4 rotates at the original position, the connecting plate 15 circularly rotates, the movable plate 7, the rotating disc 6 and the limiting plate 8 reciprocating rotate at a small angle, and the movable plate 7 relatively reciprocating slides along the rotating disc 6 and the pressing column 9.

[0044] The fixed shaft 16 is rotationally connected with the fixed frame 3, is fixedly connected with the limiting plate 8, and is rotationally connected with the rotating disc 6, which ensures that the limiting plate 8 and the rotating disc 6 independently rotate, and the rotation centers of the limiting plate 8 and the rotating disc 6 always maintain coaxial relationship.

[0045] On the one hand, the gear which reciprocating rotates at a certain angle makes the movable column 5 reciprocating move along the conveying direction of the workpiece through the sleeve joint; on the other hand, makes the movable column 5 vertically move up and down.

[0046] The description of the movable column 5 reciprocating moving under the action of the sleeve joint and the pushing of the workpiece:

[0047] The sleeve joint comprises a sleeve 10 which is fixedly connected with the inner side of the rotating disc 6, a sleeve rod 11 which is movably sleeved in the sleeve 10, an installation plate 12 which is fixedly connected between the bottoms of the two sleeve rods 11 and is fixedly installed with the plurality of movable columns 5, and a elastic member 13 which is hung between the pressing column 9 and the sleeve rod 11.

[0048] The gear reciprocating at a certain angle drives the sleeve 10 to reciprocate synchronously, so that the sleeve rod 11 in the sleeve 10 moves synchronously, and the movable column 5 on the mounting plate 12 reciprocates at a certain angle, so that the workpiece on the feeding roller shaft 4 is pushed to make the workpiece enter the annealing furnace body 2 for annealing treatment.

[0049] The movable column 5 in the vertical position contacts the workpiece (at this time, the movable column 5 moves vertically to the lowest position):

[0050] The shape of the movable plate 7 is an arc structure, when the end of the connecting plate 15 (the end connected with the movable plate 7) does the circular motion, and is in the highest position, at this time, the part of the movable plate 7 close to the annealing furnace body 2 is horizontally distributed, and the sleeve 10 and the sleeve rod 11 are in the vertical state, at this time, the distance between the abutting column 9 and the sleeve rod 11 is the shortest, the sleeve rod 11 is moved downward along the sleeve 10 by the elastic member 13 (compression spring), so that the bottom of the movable column 5 is closest to the workpiece, and the workpiece is pushed;

[0051] It is worth noting that: the plurality of movable columns 5 are distributed at an inclined angle on the mounting plate 12, and the movable column 5 in the middle position is away from the annealing furnace body 2, so that when the movable column 5 contacting the workpiece moves the workpiece, the workpiece position can be adjusted to the middle position by the guiding effect of the plurality of movable columns 5 distributed at an inclined angle, and the position of the workpiece is corresponding to the inlet 22 of the annealing furnace body 2, so that the workpiece can be accurately put into the annealing furnace body 2.

[0052] The abutting column 9 is rotatably connected with the contact column 17 rolling with the movable plate 7, because the abutting column 9 does not rotate relative to the limiting plate 8, in order to ensure that the abutting column 9 and the rotating disc 6 limit the movable plate 7, and at the same time, the movable plate 7 smoothly reciprocates along the abutting column 9, the contact column 17 rotates and the movable plate 7 rolls, so that the movable plate 7 runs smoothly.

[0053] It is worth noting that: the two sleeves 10 are fixedly connected with the limiting rod 14, which on the one hand ensures the connection between the two sleeves 10, and on the other hand avoids the accumulation of workpieces, the limiting rod 14 in the application is a back-shaped structure, which can first push the workpieces accumulated far away, and the bottom of the movable column 5 is an elastic column, which pushes the workpiece through the elastic member 13, and the elasticity of the elastic column is moderate, which ensures that the workpiece can be pushed without exceeding the elastic limit.

[0054] The connecting plate 15 is slidably connected with a U-shaped slide plate 18, the U-shaped slide plate 18 is fixedly connected with a rotation shaft 19 rotatably connected with the end of the movable plate 7, the U-shaped slide plate 18 and the connecting plate 15 are provided with screw grooves 20 for facilitating screwing, and the side of the connecting plate 15 and the inner end of the U-shaped slide plate 18 are both provided with inclined surfaces matched with each other, the angle of the reciprocating rotation of the rotating disc 6 is adjusted by sliding the U-shaped slide plate 18 along the connecting plate 15 and by cooperating the screw with the screw groove 20.

[0055] In the present application, the rotating disc 6 and the movable plate 7 are rollingly matched with each other, and the rotating disc 6 and the movable plate 7 can preferably select gears and toothed plates to ensure stable meshing rolling.

[0056] Embodiment two

[0057] Please refer to Figures 12-13 The present embodiment two is a further illustration and supplement of the embodiment one, and the U-shaped clamping column 21 can be rotatably connected with the edge of the movable plate 7 (i.e. the U-shaped clamping column 21 can be assembled and disassembled from the movable plate 7, and has high flexibility), and the elastic member 13 is located between the U-shaped clamping columns 21.

[0058] The U-shaped clamping column 21 is moved by the movable plate 7, so that the elastic member 13 is bent, thereby making the movable column 5 away from the workpiece.

[0059] When the movable column 5 and the limiting plate 8 are vertical, and the end of the connecting plate 15 (the end doing the circular motion) is located at the highest position, at this time, the elastic member 13 is vertical, and the U-shaped clamping column 21 will not bend the elastic member 13, thereby making the movable column 5 contact the workpiece and move the workpiece.
