Description

Technical Field

[0001] The present application relates to the technical field of heat treatment equipment, and in particular to a device for correcting mesh belt deviation. Background Art

[0002] Mesh belt furnaces such as quenching furnaces and tempering furnaces are heating equipment that use mesh belts to transport materials to achieve continuous sintering and / or heat treatment of materials. The mesh belt is a machine that uses static friction to transport materials in a continuous manner driven by friction. The use of mesh belts can form a material conveying process on a certain conveyor line from the initial feeding point to the final unloading point.

[0003] When the mesh belt of the existing mesh belt furnace is in operation, the mesh belt will deviate to both sides, causing the mesh belt to gradually tilt and run, resulting in excessive stretching of the mesh belt, which greatly shortens the service life of the mesh belt; the mesh belt rubs against the front desk during operation, causing the mesh belt to get stuck, ultimately causing the mesh belt furnace to stop production and the mesh belt to be damaged. Utility Model Content

[0004] Aiming at the problem that the mesh belt of the mesh belt furnace deviates during operation, the present application provides a mesh belt deviation correction device, and the specific scheme is as follows:

[0005] The mesh belt deviation correction device is arranged on the side of the mesh belt furnace close to the front desk, including a driving mechanism, an adjusting mechanism, a mesh belt adjusting roller and a mesh belt sensing mechanism, wherein:

[0014] By rotating the bearing and connecting it to the movable block, one end of the telescopic spring is connected to the movable block, and the other end is connected to the fixed block. When the mesh belt flange deviates to the left, the bearing is subjected to force, and the telescopic spring is compressed by force, causing the movable block to deviate to the left, thereby causing the left connecting rod to drive the first sensing head to the left and approach the left proximity sensor; when the mesh belt flange deviates to the right, the bearing is not subjected to force, and the telescopic spring stretches, causing the movable block to deviate to the right, thereby causing the right connecting rod to drive the second sensing head to the right and approach the right proximity sensor.

[0038] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figures 1 to 4 As shown, the present application provides a mesh belt deviation correction device, which is installed on the side of the mesh belt furnace close to the front desk 100, including a driving mechanism 2, an adjustment mechanism 3, a mesh belt adjustment roller 4 and a mesh belt sensing mechanism 1, wherein:

[0040] The mesh belt adjusting roller 4 is in contact with the lower surface of the mesh belt, the driving mechanism 2 is connected to the adjusting mechanism 3, the mesh belt sensing mechanism 1 is electrically connected to the driving mechanism 2, and the adjusting mechanism 3 is used to adjust the position of the mesh belt adjusting roller 4;

[0041] The driving mechanism 2 drives the adjusting mechanism 3 to drive the mesh belt adjusting roller 4 to move forward or backward based on the signal sent by the mesh belt sensing mechanism 1.

[0042] The present application uses a mesh belt sensing mechanism 1 to sense the deviation direction of the mesh belt and transmits a signal of the deviation direction to a driving mechanism 2. The driving mechanism 2 drives the adjusting mechanism 3 to drive the mesh belt adjusting roller 4 to move forward or backward according to the received signal, so that the mesh belt adjusting roller 4 is in an initial balanced state, thereby returning the mesh belt to the correct position, avoiding the mesh belt from getting stuck or over-stretching due to deviation, and improving the service life of the mesh belt.

[0043] like Figures 5 to 8As shown, the mesh belt sensing mechanism 1 includes a base 15, a mounting assembly, a bearing 16, a telescopic spring 17, a proximity sensor and a sensing head. The base 15 is fixed on one side of the mesh belt furnace, the fixed part of the mounting assembly is fixed on the base 15, the bearing 16 is rotatably mounted on the movable part of the mounting assembly, one end of the telescopic spring 17 is connected to the movable part of the mounting assembly, and the other end is connected to the fixed part of the mounting assembly, the proximity sensor is fixed on the base 15, and the sensing head is arranged on the mounting assembly and is used to control the proximity sensor to transmit a signal.

[0044] refer to Figures 5 to 7 The installation assembly includes two fixed blocks 19, a movable block 18 and two connecting rods 110. The two fixed blocks 19 are fixed on the base 15 at intervals. Two guide holes are provided on the fixed blocks 19, and a mounting hole is provided in the center of one of the fixed blocks 19. One end of the two connecting rods 110 is fixed on the movable block 18, and the other end passes through the guide hole and extends outward. The aperture of the guide hole is larger than the rod diameter of the connecting rod 110; the first induction head 13 and the second induction head 14 are respectively connected to one end of the two connecting rods 110; one end of the telescopic spring 17 is connected to the movable block 18, and the other end passes through the mounting hole and is connected to the other fixed block 19, and the bearing 16 is rotatably connected to the movable block 18.

[0045] Continue to refer Figures 5 to 7 The proximity sensor includes a left proximity sensor 11 and a right proximity sensor 12; the sensing head includes a first sensing head 13 and a second sensing head 14; the first sensing head 13 is used to control the left proximity sensor 11 to transmit a signal, and the second sensing head 14 is used to control the right proximity sensor 12 to transmit a signal.

[0046] The working process of the mesh belt sensing mechanism 1 is as follows: when the bearing 16 contacts the mesh belt flange 5, and the telescopic spring 17 is in a balanced compression state, the two sensing heads are exactly in the middle position of the proximity sensors on the left and right, and the proximity sensors cannot sense any signal;

[0047] When the mesh belt deviates to the left, the bearing 16 is pressed by the mesh belt flange 5, the telescopic spring 17 is compressed, and the movable block 18 deviates to the left, so that the connecting rod 110 drives the first sensing head 13 to the left and approaches the left proximity sensor 11. The left proximity sensor senses the first sensing head 13 and transmits a signal to the driving mechanism 2 at the same time.

[0048] When the mesh belt deviates to the right, the bearing 16 is not compressed by the mesh belt flange 5, and the movable block 18 moves to the right under the extension of the telescopic spring 17, so that the connecting rod 110 drives the second sensor head 14 to the right and approaches the right proximity sensor 12. The right proximity sensor senses the second sensor head 14 and transmits a signal to the driving mechanism 2 at the same time.

[0049] like Fig. 9As shown, the adjustment mechanism includes two slide rails 32, a slider 33, a roller shaft and a supporting plate 31, wherein: the supporting plate 31 is fixed on one side of the mesh belt furnace, and a guide groove 311 is provided on the supporting plate 31; the slide rail 32 is horizontally arranged and fixed on the supporting plate 31, and the two slide rails 32 are symmetrically installed on the upper and lower sides of the guide groove 311, one end of the roller shaft is fixed on one side of the mesh belt furnace, and the other end is accommodated in the guide groove 311 and connected to the slider 33; the slider 33 is slidably installed on the slide rail 32, the slider 33 is connected to the driving mechanism 2, and the mesh belt adjustment roller 4 is sleeved on the roller shaft.

[0050] Optional, such as Fig. 9 As shown, the driving mechanism 2 includes an AC motor 21, a screw 22 and a screw nut 23, wherein: the screw 22 is connected to the driving end of the AC motor 21, and the screw nut 23 is sleeved on the screw 22; the slider 33 is connected to the screw nut 23, and the AC motor 21 is electrically connected to the proximity sensor.

[0051] The specific working process of the driving mechanism 2 and the adjusting mechanism 3 is as follows:

[0052] When the AC motor 21 drives the lead screw 22 to rotate based on the signal from the left proximity sensor 11, it drives the lead screw nut 23 and the slider 33 to move to the right, so that the roller shaft moves forward along the guide groove 311. At this time, the mesh belt adjusting roller 4 is in a state of slightly tilting forward, and the mesh belt will naturally shift to the right during the movement. After a period of time, the AC motor 21 makes the lead screw nut 23 and the slider 33 return to the initial position, and the roller shaft also returns to the initial position. The mesh belt adjusting roller 4 returns to the balanced position, and the mesh belt returns to the normal position.

[0053] Similarly, when the AC motor 21 drives the lead screw 22 to rotate based on the signal from the right proximity sensor 12, it drives the lead screw nut 23 and the slider 33 to move to the left, causing the roller shaft to move backward along the guide groove 311. At this time, the mesh belt adjusting roller 4 is in a state of slight backward tilt, and the mesh belt will naturally shift to the left during movement. After a period of time, the AC motor 21 returns the lead screw nut 23 and the slider 33 to their initial positions, and the roller shaft also returns to their initial positions. The mesh belt adjusting roller 4 returns to the balanced position, and the mesh belt returns to the normal position.

[0054] The application has a simple structure, low cost, and is easy for staff to maintain.

[0055] The principle of the mesh belt deviation correction implemented in the present application is as follows: the mesh belt sensing mechanism 1 is used to sense the deviation of the mesh belt to the left or right. When the mesh belt deviation is sensed, a signal will be transmitted to the driving mechanism 2. After the driving mechanism 2 receives the signal, the output end of the driving mechanism 2 drives the adjusting mechanism 3 to move to the right or left by rotating, so that the mesh belt adjusting roller 4 moves forward or backward to correct the deviation of the mesh belt; after adjusting for a period of time, the driving mechanism 2 drives the adjusting mechanism 3 back to the initial position, and the mesh belt adjusting roller 4 returns to the balanced position, and the mesh belt is basically back to the original position. In this way, after adjusting once or twice, the deviation of the mesh belt is corrected. Since the mesh belt adjusting roller 4 is in a balanced position, the probability of the mesh belt deviation will also be reduced.

[0056] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
