Description

Technical Field

[0001] This utility model belongs to the field of cold rolling mill technology, and in particular relates to a waste recycling device for cold rolling mills. Background Technology

[0002] Cold rolling uses hot-rolled steel coils as raw materials, and after pickling to remove oxide scale, it is continuously cold rolled. The finished product is hard-rolled coil. Due to the work hardening caused by continuous cold deformation, the strength and hardness of the hard-rolled coil increase and the toughness and plasticity decrease. Therefore, the stamping performance will deteriorate, and it can only be used for parts with simple deformation.

[0003] Waste is generated during cold rolling. To improve the utilization rate of waste, it is remelted. However, the waste is generally static in the melting furnace, and its accumulation slows down heat transfer, thus affecting the melting rate. Therefore, we provide a waste recycling device for cold rolling mills to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a waste recycling device for cold rolling mills. A first spur gear drives a rotating rod to reciprocate, which in turn drives a mixing rod to reciprocate. Because two toothed plates are staggered on the outer side of the first spur gear, the two rotating rods rotate in opposite directions, causing the mixing rods on both sides to rotate in opposite directions. This further accelerates the rapid tumbling of the waste inside the melting chamber, thereby speeding up the uniform heating of the waste and increasing the melting rate. This solves the problem that in existing waste remelting systems, the waste is generally stationary in the melting furnace, and the accumulation of waste slows heat transfer, thus affecting the melting rate.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] This utility model relates to a waste recycling device for a cold rolling mill, comprising a support assembly. The support assembly includes a base, an L-shaped support rod fixedly connected to the top of the base, an arc-shaped mounting plate fixedly connected to the end of the L-shaped support rod, and a melting assembly fixedly fitted to the inner circumferential side of the arc-shaped mounting plate. The melting assembly includes a melting box fixedly connected to the inner circumferential side of the arc-shaped mounting plate, a rotating rod symmetrically rotatably connected to the bottom of the melting box, several mixing rods symmetrically fixedly connected to the circumferential side of the rotating rod, a first spur gear fixedly connected to the bottom of the rotating rod, and a discharge pipe connected to the bottom of the melting box. A reciprocating drive assembly is slidably fitted to the top of the base, the reciprocating drive assembly including a first sliding plate slidably connected to the top of the base, a connecting plate fixedly connected to the top of the first sliding plate, toothed plates corresponding to and meshing with the first spur gear fixedly connected to both opposite sides of the connecting plate, and an L-shaped rod fixedly connected to one side of the first sliding plate.

[0007] The present invention is further configured such that a crushing assembly is fixedly fitted to the top of the melting box, the crushing assembly includes a crushing box connected to the top of the melting box, a first rotating shaft is symmetrically rotatably connected inside the crushing box, and a second spur gear is fixedly connected to the end of the first rotating shaft.

[0008] The present invention is further configured such that a motor is fixedly connected to one outer side of the crushing box, a transmission rod is fixedly connected to the drive end of the motor, a third spur gear that meshes with one of the second spur gears is fixedly connected to the circumferential side of the transmission rod, a first sprocket is fixedly connected to the end of the transmission rod, and a crushing roller is fixedly connected to the circumferential side of the first rotating shaft.

[0009] The present invention is further configured such that a reciprocating moving component is fixedly fitted to the top of the base, the reciprocating moving component includes a vertical plate fixedly connected to the top of the base, a second rotating shaft is rotatably connected to one side of the vertical plate, a second sprocket is fixedly connected to the circumferential side of the second rotating shaft, and a chain is meshed between the first sprocket and the second sprocket.

[0010] The present invention is further configured such that a disc is fixedly connected to the end of the second rotating shaft, a connecting column is fixedly connected to one side of the disc at an eccentric position, a second sliding plate is slidably connected to the top of the base, a rectangular frame that slides with the connecting column is fixedly connected to the top of the second sliding plate, and the rectangular frame and the L-shaped rod are fixedly connected.

[0011] The present invention is further configured such that the support component includes a first guide groove formed on the top of the base, the first slide plate is slidably engaged with the first guide groove, and the top of the base is provided with a second guide groove that slidably engages with the second slide plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model involves feeding crushed waste material into a melting chamber, then heating the melting chamber to transfer heat to the waste material, thereby melting the waste material. Simultaneously, the connecting plate is controlled to move back and forth, causing the connecting plate to drive two toothed plates to move back and forth. The toothed plates drive the meshing first spur gear, which in turn drives the rotating rod to rotate back and forth, further driving the mixing rod to rotate back and forth. Since the two toothed plates are staggered and distributed on the outside of the first spur gear, the two rotating rods rotate in opposite directions, which in turn causes the mixing rods on both sides to rotate in opposite directions. This further accelerates the rapid tumbling of the waste material inside the melting chamber, thereby accelerating the uniform heating of the waste material and increasing the melting rate of the waste material.

[0014] 2. This utility model controls the motor to drive the transmission rod to rotate, which in turn drives the third spur gear and the first sprocket to rotate. The third spur gear drives the meshing second spur gear to rotate, which in turn drives the crushing roller to rotate through the first rotating shaft. Then, the waste material is fed between the two crushing rollers, thereby completing the crushing of the waste material and improving the subsequent melting rate of the waste material.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0030] Please see Figure 1-9 This utility model relates to a waste recycling device for a cold rolling mill, comprising a support assembly 1; the support assembly 1 includes a base 101, an L-shaped support rod 102 fixedly connected to the top of the base 101, an arc-shaped mounting plate 103 fixedly connected to the end of the L-shaped support rod 102, and a melting assembly 2 fixedly fitted to the inner circumferential side of the arc-shaped mounting plate 103; the melting assembly 2 includes a melting box 201 fixedly connected to the inner circumferential side of the arc-shaped mounting plate 103, a rotating rod 202 symmetrically rotatably connected to the inner bottom of the melting box 201, and several symmetrically fixedly connected to the circumferential side of the rotating rod 202. The bottom end of the mixing rod 203 and the rotating rod 202 is fixedly connected to the first spur gear 204. The bottom of the melting box 201 is connected to the discharge pipe 205. The top of the base 101 is slidably fitted with the reciprocating drive assembly 3. The reciprocating drive assembly 3 includes a first slide plate 301 slidably connected to the top of the base 101. The top of the first slide plate 301 is fixedly connected to the connecting plate 302.

One side of the first slide plate 301 is fixedly connected to the L-shaped rod 304.

[0031] The operation process of this embodiment is as follows: the crushed waste material is put into the melting box 201, and then the melting box 201 is heated to transfer heat to the waste material, thereby melting the waste material. Simultaneously, the connecting plate 302 is controlled to move back and forth, causing the connecting plate 302 to drive the two toothed plates 303 to move back and forth. The toothed plates 303 drive the meshing first spur gear 204, causing the first spur gear 204 to drive the rotating rod 202 to rotate back and forth, further driving the mixing rod 303 to rotate back and forth. Since the two toothed plates 303 are correspondingly and alternately distributed on the outside of the first spur gear 204, the two rotating rods 202 rotate in opposite directions, thereby causing the mixing rods 203 on both sides to rotate in opposite directions. This further accelerates the rapid tumbling of the waste material inside the melting box 201, thereby accelerating the uniform heating of the waste material and increasing the melting rate of the waste material.

A first sprocket 407 is fixedly connected to the end of the transmission rod 405. A crushing roller 408 is fixedly connected to the circumferential side of the first rotating shaft 402.

[0034] The operation process of this embodiment is as follows: the control motor 404 drives the transmission rod 405 to rotate, which in turn drives the third spur gear 406 and the first sprocket 407 to rotate. The third spur gear 406 drives the meshing second spur gear 403 to rotate, which in turn drives the crushing roller 408 to rotate through the first rotating shaft 402.
