Description

Technical Field

[0001] The invention relates to the technical field of lead smelting slag recovery, and in particular to a crushing device for improving the recovery efficiency of lead smelting slag. Background Art

[0002] In the process of lead smelting, smelting slag is a by-product, and its treatment and recycling have always been the focus of the industry. Traditional lead smelting slag treatment methods often have problems such as low efficiency, high energy consumption, and poor crushing effect, resulting in a large amount of valuable metals and other resources not being effectively recycled, which not only wastes resources but also increases the environmental burden. With the enhancement of environmental awareness and the popularization of the concept of resource recycling, improving the recycling efficiency of lead smelting slag has become a key issue that the industry needs to solve urgently.

[0003] The patent with announcement number CN218924772U discloses a crushing device for lead-zinc smelting slag. It adds a motor and a rotating shaft to the outside of the crushing box, which is transmitted to the fine crusher through a chain, so that the fine crusher can be driven alone. The material that is not completely crushed by the fixed jaw plate and the movable jaw plate is crushed more thoroughly under the action of the fine crusher, which not only realizes the screening of the smelting slag after crushing, but also solves the problem of insufficient crushing, avoids repeated crushing, and improves efficiency.

[0004] Although the above scheme can crush the lead smelting slag evenly and improve subsequent utilization efficiency, in the process of the movable jaw plate moving toward the fixed jaw plate, the power source driving the movable jaw plate can be converted into the power source for crushing the lead smelting slag, and in the process of the movable jaw plate moving away from the fixed jaw plate, the power source driving the movable jaw plate can only drive the movable jaw plate to move, so that the mechanical energy of the movable jaw plate moving away from the fixed jaw plate cannot be fully utilized.

[0011] Preferably, the secondary crushing structure includes two mutually parallel arc-shaped mounting frames. A plurality of second rotating shafts are arranged between the two arc-shaped mounting frames, and each second rotating shaft corresponds to a strip-shaped discharge groove on the arc-shaped crushing plate.

[0012] Preferably, the secondary crushing structure further includes a plurality of linkage components, and the plurality of linkage components connect two adjacent second rotating shafts.

[0013] Preferably, the crushing drive structure includes a drive shaft parallel to the main shaft and connected to the frame through a bearing.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] 1. The present invention is provided with a crushing box, an arc-shaped crushing, an eccentric crushing structure, a secondary crushing structure and a crushing drive structure. Driven by the eccentric crushing structure, the arc-shaped pressing plate realizes reciprocating motion through the rotation of the main shaft. The reciprocating motion of the main shaft makes the gap between the arc-shaped pressing plate and the arc-shaped crushing plate change periodically, forming a sucking effect on the lead smelting slag. When the arc-shaped pressing plate moves to one side, the gap increases, sucking the lead smelting slag. When moving to the other side, the gap decreases, squeezing and crushing the sucked lead smelting slag. The synchronous progress of such material taking and crushing greatly improves the working efficiency. The secondary crushing structure further finely processes the lead smelting slag after primary crushing, effectively reducing the particle size of the material and improving the recovery rate. Through secondary crushing, it can be ensured that the lead smelting slag is crushed to a smaller size to meet the requirements of subsequent treatment or recovery. Within one rotation cycle of the main shaft, the arc-shaped pressing plate crushes the lead smelting slag in both the first crushing chamber and the second crushing chamber, thus realizing the two-way crushing of the lead smelting slag by the arc-shaped pressing plate and significantly reducing the production energy consumption.

[0018] 2. The present invention is provided with two crushing tooth assemblies. When the crushing tooth assemblies contact the lead smelting slag, the resistance of the lead smelting slag during movement is increased, preventing the rolling of spherical particles and ensuring that the slag material can enter the narrower channel formed between the arc-shaped pressing plate and the arc-shaped crushing plate more deeply, thus effectively avoiding the situation that some lead smelting slag rolls and is not fully squeezed and crushed.

[0019] 3. The present invention alternately arranges the first tooth plate and the second tooth plate. The first crushing teeth on the first tooth plate and the second crushing teeth on the second tooth plate are arranged in an interlaced manner, forming a complementary crushing effect. After the lead smelting slag is initially crushed, it can be quickly secondarily crushed by the adjacent second crushing teeth, thus ensuring that the lead smelting slag can be fully and evenly crushed and effectively improving the crushing effect.

Detailed implementation manners

[0033] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0034] Refer to Figures 1 to 12 As shown in the figure: A crushing device for improving the recycling efficiency of lead smelting slag includes a crushing box 1, an arc-shaped crushing plate 2, an eccentric crushing structure 3, a secondary crushing structure 4 and a crushing drive structure 5; a plurality of strip-shaped discharge grooves are formed on the arc-shaped crushing plate 2, and the arc-shaped crushing plate 2 divides the interior of the crushing box 1 into a crushing chamber and a discharging chamber, and a discharging structure 6 capable of quickly discharging materials is arranged in the discharging chamber; the eccentric crushing structure 3 includes a frame 31, a main shaft 32 parallel to the axis of the arc-shaped crushing plate 2 and located above the arc-shaped crushing plate 2 is arranged on the frame 31, an eccentric connecting frame 321 is arranged on the main shaft 32, an arc-shaped extrusion plate 33 is installed on the eccentric connecting frame 321, and the axis of the main shaft 32 deviates from the axis of the arc-shaped extrusion plate 33; the secondary crushing structure 4 is arranged at the lower end of the arc-shaped crushing plate 2; the crushing drive structure 5 is arranged on one side of the frame 31, and the crushing drive structure 5 is used to drive the eccentric crushing structure 3 and the secondary crushing structure 4 to operate.

[0035] When the arc-shaped extrusion plate 33 is symmetric about the main shaft 32, the crushing chamber is divided by the arc-shaped extrusion plate 33 into a first crushing chamber and a second crushing chamber with the same volume. And a passage connecting the first crushing chamber and the second crushing chamber is formed between the arc-shaped crushing plate 2 and the arc-shaped extrusion plate 33. The passage is relatively narrow. And at this time, the distance between the lowest point of the arc-shaped crushing plate 2 and the arc-shaped extrusion plate 33 is the largest. When one end of the arc-shaped extrusion plate 33 moves to the lowest point of the arc-shaped crushing plate 2, the distance between the end of the arc-shaped extrusion plate 33 and the arc-shaped crushing plate 2 is the smallest. Therefore, during the operation of the eccentric crushing structure 3, the distance between the arc-shaped extrusion plate 33 and the arc-shaped crushing plate 2 changes at all times.

[0036] When crushing, first put the lead smelting slag into the first crushing chamber and the second crushing chamber. Since the passage between the arc-shaped crushing plate 2 and the arc-shaped extrusion plate 33 is relatively narrow, the lead smelting slag cannot enter the passage immediately. When the crushing drive structure 5 is started and drives the main shaft 32 to rotate clockwise, the eccentric connecting frame 321 drives the arc-shaped extrusion plate 33 to move towards the first crushing chamber. During this process, the gap between the arc-shaped extrusion plate 33 and the arc-shaped crushing plate 2 gradually increases, forming a suction effect on the lead smelting slag in the first crushing chamber, realizing the first material taking. Subsequently, the main shaft 32 rotates counterclockwise, and the arc-shaped extrusion plate 33 moves towards the second crushing chamber accordingly. During this process, the previously sucked lead smelting slag is squeezed by the arc-shaped extrusion plate 33, moves towards the lowest point of the arc-shaped crushing plate 2 and is squeezed and crushed. At the same time, the other end of the arc-shaped extrusion plate 33 enters the second crushing chamber for the second material taking. The main shaft 32 rotates clockwise again, not only continues to squeeze and crush the lead smelting slag taken for the second time, but also enters the first crushing chamber for a new round of material taking. This reciprocating process realizes the synchronous progress of material taking and crushing, greatly improving the working efficiency. The lead smelting slag that has completed one crushing falls onto the secondary crushing structure 4 through the strip-shaped discharge groove on the arc-shaped crushing plate 2. The secondary crushing structure 4 further finely processes these preliminarily crushed lead smelting slags, effectively reducing the particle size of the materials and improving the recycling rate. Finally, the lead smelting slag that has been secondarily crushed is discharged from the crushing box 1 under the action of the discharge structure 6, completing the entire crushing process. Through the continuous operation of the crushing drive structure 5, the main shaft 32 can swing reciprocally, driving the arc-shaped extrusion plate 33 to perform reciprocating motion inside the arc-shaped crushing plate 2, thereby realizing the two-way crushing of the lead smelting slag by the arc-shaped extrusion plate 33 and significantly reducing the production energy consumption.

[0037] Refer to Figure 3 and Figure 4 As shown: The eccentric crushing structure 3 further includes two crushing tooth assemblies 34, and the two crushing tooth assemblies 34 are symmetrically arranged on the convex surface of the arc-shaped extrusion plate 33.

[0038] When the arc-shaped extrusion plate 33 reciprocates inside the arc-shaped crushing plate 2, through the change in the distance between the arc-shaped extrusion plate 33 and the arc-shaped crushing plate 2, effective extrusion and crushing of lead smelting slag are achieved. Among the lead smelting slag, some particles are spherical. If the surface of the arc-shaped extrusion plate 33 is too smooth, during the movement process, these spherical particles are prone to rolling under the action of thrust. Therefore, two crushing tooth assemblies 34 are added on the convex surface of the arc-shaped extrusion plate 33. During the reciprocating movement of the arc-shaped extrusion plate 33, these two crushing tooth assemblies 34 come into contact with the lead smelting slag in sequence and alternately. When the crushing tooth assembly 34 contacts the lead smelting slag, the arc-shaped extrusion plate 33 exerts a force on the lead smelting slag towards the arc-shaped crushing plate 2. This force increases the resistance of the lead smelting slag during the movement process, ensuring that the slag material can enter the narrower channel formed between the arc-shaped extrusion plate 33 and the arc-shaped crushing plate 2 more deeply, thereby effectively avoiding the situation of insufficient extrusion and crushing caused by the rolling of some lead smelting slag.

[0039] Refer to Figure 4 and Figure 5 As shown: The crushing tooth assembly 34 includes a plurality of first tooth plates 341 and second tooth plates 342 alternately installed on the arc-shaped crushing plate 2. A plurality of first crushing teeth 3411 are provided on the first tooth plate 341, and a plurality of second crushing teeth 3421 are provided on the second tooth plate 342. Moreover, the second crushing teeth 3421 on the second tooth plate 342 are located between two adjacent first crushing teeth 3411 on the first tooth plate 341.

[0040] The mutually staggered first crushing teeth 3411 and second crushing teeth 3421 form a complementary crushing effect. During the working process, the first tooth plate 341 at the lowermost position in the crushing tooth assembly 34 first comes into contact with the lead smelting slag. At this time, the plurality of first crushing teeth 3411 on the first tooth plate 341 exert pressure on the lead smelting slag to perform a preliminary extrusion and crushing operation. At this stage, after being squeezed by the first crushing teeth 3411, the crushed lead smelting slag will disperse along both sides of the first crushing teeth 3411. Subsequently, the second tooth plate 342 moves along the movement trajectory to the position where the first tooth plate 341 was previously located. At this time, the second crushing teeth 3421 on the second tooth plate 342 perform a secondary crushing treatment on the lead smelting slag that has been preliminarily crushed by the first crushing teeth 3411. During this process, the lead smelting slag is further refined under the action of the second crushing teeth 3421 and disperses again to both sides of the second crushing teeth 3421. The subsequent first tooth plate 341 and second tooth plate 342 take turns in sequence to perform continuous crushing operations on the lead smelting slag. This alternating crushing mechanism enhances the crushing efficiency, thereby ensuring that the lead smelting slag can be fully and evenly crushed, effectively improving the crushing effect.

[0041] Refer to Figure 3 ,Figure 4 and Figure 5 As shown in Figure 5 , the eccentric crushing structure 3 further includes an adjustment structure 35. The adjustment structure 35 includes a fixing plate 351 and an adjustment driving structure 352 disposed in the middle of the fixing plate 351. Height adjustment components 353 connected to the ends of the main shaft 32 are provided at both ends of the adjustment driving structure 352, and the adjustment driving structure 352 is in transmission connection with the two height adjustment components 353.

[0042] Specifically, the adjustment driving structure 352 includes a first rotating shaft 3521 and two bevel gear sets 3522. The first rotating shaft 3521 is parallel to the main shaft 32. The two bevel gear sets 3522 are connected to both ends of the first rotating shaft 3521. The height adjustment component 353 includes a rectangular frame 3531, a double-headed lead screw 3532, two first moving blocks 3533, two driving plates 3534, a first bearing seat 3535, and a guiding telescopic rod 3536. The rectangular frame 3531 is fixed to the end of the fixing plate 351. Both ends of the double-headed lead screw 3532 are connected to the rectangular frame 3531. The end of the first rotating shaft 3521 extends into the interior of the rectangular frame 3531, and the first rotating shaft 3521 and the double-headed lead screw 3532 are connected by the bevel gear sets 3522. The two first moving blocks 3533 are respectively connected to the two threaded portions of the double-headed lead screw 3532. The two driving plates 3534 are respectively pivotally connected to the two first moving blocks 3533. The first bearing seat 3535 is connected to the end of the rotating shaft. Both ends of the first bearing seat 3535 are pivotally connected to the two driving plates 3534. The guiding telescopic rod 3536 is disposed between the two driving plates 3534, and the guiding telescopic rod 3536 is connected to the first bearing seat 3535.

[0043] When all the lead smelting slag in the crushing box 1 is crushed, there may be some lead smelting slag with smaller particles that has not been crushed by extrusion. Therefore, an adjusting structure 35 is provided. When it is necessary to further crush the remaining lead smelting slag by extrusion, the adjusting drive structure 352 starts to operate. The first rotating shaft 3521 rotates and is transmitted to the two height adjusting components 353 through the two bevel gear sets 3522 respectively. Inside each height adjusting component 353, the end of the first rotating shaft 3521 extends into the rectangular frame 3531 and is in transmission connection with the double-headed lead screw 3532 through the bevel gear set 3522. As the first rotating shaft 3521 rotates, the double-headed lead screw 3532 rotates accordingly. The two threaded parts on the double-headed lead screw 3532 drive the two first moving blocks 3533 to move away from each other along the axis of the lead screw respectively. The two drive plates 3534 are respectively pivotally connected to the two first moving blocks 3533. Therefore, the drive plates 3534 move respectively following the movement of the two first moving blocks 3533. During the movement, the two drive plates 3534 exert a downward thrust on the first bearing block 3535, prompting the first bearing block 3535 to move downward. At the same time, the guiding telescopic rod 3536 arranged between the two drive plates 3534 contracts to limit and guide the movement of the first bearing block 3535 to ensure the movement stability of the first bearing block 3535. Since the two height adjusting components 353 operate simultaneously, both ends of the main shaft 32 are simultaneously subjected to downward forces, realizing the smooth downward movement of the main shaft 32, making the distance between the arc-shaped extrusion plate 33 and the arc-shaped crushing plate 2 gradually decrease, providing conditions for further extrusion crushing. At this time, the crushing drive structure 5 drives the eccentric crushing structure 3 to move again, so that the arc-shaped extrusion plate 33 and the arc-shaped crushing plate 2 effectively crush the lead smelting slag smaller than the channel size between them, thereby enabling the eccentric crushing structure 3 to crush lead smelting slag of different sizes.

[0044] Refer to Figure 4 and Figure 6 As shown: The adjusting structure 35 further includes two fixing structures 354. The two fixing structures 354 are respectively arranged at both ends of the fixing plate 351, and the two fixing structures 354 are respectively connected to both ends of the main shaft 32. The fixing structure 354 is used to fix the position of the main shaft 32.

[0045] Specifically, the fixed structure 354 includes two mutually parallel first connecting plates 3541 and two mutually parallel first guide rods 3542. The two first connecting plates 3541 and the two first guide rods 3542 enclose a rectangle. A second bearing block 3543 slidably connected to the two first guide rods 3542 is arranged between the two first guide rods 3542. The middle of the second bearing block 3543 is connected to the end of the main shaft 32. A first spring 3544 is sleeved on each of the two first guide rods 3542. The two ends of the first spring 3544 respectively abut against the first connecting plate 3541 and the second bearing block 3543. The first spring 3544 is used to apply an upward acting force along the axis direction of the first guide rod 3542 to the second bearing block 3543. A downward pressing driver 3545 is arranged at the upper end of the second bearing block 3543. The downward pressing driver 3545 is used to apply a downward acting force along the axis direction of the first guide rod 3542 to the second bearing block 3543.

[0046] When the arc-shaped pressing plate 33 presses and crushes the lead smelting slag, the arc-shaped pressing plate 33 will receive a reaction force. This reaction force is transmitted to the two height adjusting components 353 through the main shaft 32, so that the double-headed screw rod 3532 in the height adjusting component 353 receives an upward force, making it easy for the double-headed screw rod 3532 to bend. Therefore, two fixed structures 354 are provided. When the adjusting drive structure 352 and the two adjusting components adjust the position of the main shaft 32, the main shaft 32 drives the second bearing block 3543 along the two first guide rods 3542. After the main shaft 32 stops moving, the downward pressing driver 3545 contacts the second bearing block 3543 to limit the second bearing block 3543. The reaction force received by the main shaft 32 will act on the two downward pressing drivers 3545 through the two second bearing blocks 3543, so that the reaction force cannot be transmitted to the two height adjusting components 353, thereby effectively enhancing the stability of the main shaft 32 during operation and reducing the risk of deformation of the height adjusting component 353 caused by the reaction force.

[0047] Refer to Figure 3 and Figure 7 As shown: The secondary crushing structure 4 includes two mutually parallel arc-shaped mounting frames 41. A plurality of second rotating shafts 42 are arranged between the two arc-shaped mounting frames 41, and each second rotating shaft 42 corresponds to a strip-shaped discharge slot on the arc-shaped crushing plate 2. A crushing roller 43 is arranged on the second rotating shaft 42, and two adjacent crushing rollers 43 are engaged with each other.

[0048] In the crushing process of lead smelting slag, there are differences in the particle sizes of the lead smelting slag after preliminary extrusion crushing. When these particles can pass through the strip-shaped discharge chute on the arc-shaped crushing plate 2, the lead smelting slag particles fall into the secondary crushing area below. At this time, two adjacent crushing rolls 43 rotate in opposite directions to form an effective biting effect. After the lead smelting slag enters the biting area, it is subjected to the re-crushing action from the two crushing rolls 43. Through the secondary crushing mechanism, the lead smelting slag is further refined, ensuring the uniformity of the particle sizes of the final crushed product, thus making the subsequent treatment or recycling of the lead smelting slag more convenient and efficient.

[0049] Refer to Figure 7 and Figure 8 As shown: The secondary crushing structure 4 further includes a number of linkage components 44, and the number of linkage components 44 connects two adjacent second rotating shafts 42.

[0050] Specifically, the linkage component 44 includes two linkage wheels 441. The two linkage wheels 441 are respectively connected to two adjacent second rotating shafts 42, and the two linkage wheels 441 are meshed with each other.

[0051] One of the second rotating shafts 42 among the multiple second rotating shafts 42 is in transmission connection with the crushing drive structure 5. When the crushing drive structure 5 is started, it will drive this second rotating shaft 42 to rotate. Subsequently, the rotating second rotating shaft 42 transmits the power to another linkage wheel 441 on the adjacent second rotating shaft 42 through one of the linkage wheels 441 connected to it. Since the two linkage wheels 441 are meshed with each other, the adjacent second rotating shaft 42 will be driven to rotate in the opposite direction. This transmission process will be sequentially transmitted through multiple groups of meshed linkage wheels 441, so that the adjacent two second rotating shafts 42 in the entire secondary crushing structure 4 can rotate in opposite directions, thus ensuring the effective biting between the crushing rolls 43 and realizing the secondary crushing of the lead smelting slag.

[0052] Refer to Figure 3 、 Figure 9 and Figure 10 As shown: The crushing drive structure 5 includes a drive shaft 51 parallel to the main shaft 32 and connected to the frame 31 through a bearing. A first transmission component 52 connected to the secondary crushing structure 4 and a second transmission component 53 connected to the main shaft 32 are provided on the drive shaft 51. A reciprocating swing component 54 is arranged on the frame 31, and the reciprocating swing component 54 is connected to the drive shaft 51.

[0053] Specifically, the first transmission assembly 52 includes two first transmission wheels 521 and a first transmission belt 522. The two first transmission wheels 521 are respectively connected to the second rotating shaft 42 and the drive shaft 51. The first transmission belt 522 is sleeved on the two first transmission wheels 521. The second transmission assembly 53 includes two second transmission wheels 531 and a second transmission belt 532. The two second transmission wheels 531 are respectively connected to the main shaft 32 and the drive shaft 51. The second transmission belt 532 is sleeved on the two second transmission wheels 531.

[0054] When the crushing drive structure 5 is started, the reciprocating swing assembly 54 starts to work, applying a reciprocating rotational force to the drive shaft 51. This force causes the drive shaft 51 to start reciprocating rotation. During the rotation of the drive shaft 51, the first transmission wheel 521 on the drive shaft 51 rotates accordingly, and transmits power to the first transmission wheel 521 on the second rotating shaft 42 in the secondary crushing structure 4 through the first transmission belt 522, driving the second rotating shaft 42 to start rotating. At the same time, the second transmission wheel 531 on the drive shaft 51 also rotates with the drive shaft 51, and transmits power to the second transmission wheel 531 on the main shaft 32 through the second transmission belt 532, thereby driving the main shaft 32 to rotate, achieving the synchronous operation of the eccentric crushing structure 3 and the secondary crushing structure 4, and improving the crushing efficiency and working coordination.

[0055] Refer to Figure 10 and Figure 11 As shown: The crushing drive structure 5 further includes a transmission adjustment assembly 55. The transmission adjustment assembly 55 is arranged on one side of the second transmission assembly 53, and the transmission adjustment assembly 55 is used to maintain the transmission effect of the second transmission assembly 53.

[0056] Specifically, the transmission adjustment assembly 55 includes a second guide rod 551, two second moving blocks 552, two second springs 553 and two auxiliary wheels 554. The second guide rod 551 is perpendicular to the connection line between the two second transmission wheels 531. The two second moving blocks 552 are both slidably arranged on the second guide rod 551. The two second springs 553 are respectively sleeved on both ends of the second guide rod 551. The second springs 553 are used to apply a force to the second moving blocks 552 towards the middle of the second guide rod 551. The two auxiliary wheels 554 are respectively axially connected to the two second moving blocks 552, and both of the two auxiliary wheels 554 are in contact with the second transmission belt 532.

[0057] Since the height of the main shaft 32 is adjustable, the distance between the two second driving wheels 531 will change, resulting in a change in the driving effect of the second driving belt 532. By providing a driving adjustment assembly 55, two second springs 553 in the driving adjustment assembly 55 respectively apply an inward acting force on the two second moving blocks 552, such that the two auxiliary wheels 554 apply an acting force towards the middle of the second driving belt 532, and the second driving belt 532 also applies an opposite acting force on the two auxiliary wheels 554. When the distance between the two second driving wheels 531 shortens, the acting force applied by the second driving belt 532 on the two auxiliary wheels 554 decreases. Therefore, the two second springs 553 will push the two second moving blocks 552 closer to each other, causing the auxiliary wheels 554 to be in close contact with the second driving belt 532. The circulating path of the second driving belt 532 changes, maintaining the tension of the second driving belt 532 unchanged, so as to ensure that the driving effect between the drive shaft 51 and the main shaft 32 is not affected.

[0058] Refer to Figure 10 and Figure 12 As shown: The reciprocating swing assembly 54 includes a second connecting plate 542 and a reciprocating movement assembly 541 for driving the second connecting plate 542 to reciprocate horizontally. A transmission rod 543 is pivotally connected to the middle of the second connecting plate 542. One end of the transmission rod 543 perpendicularly passes through the axis of the drive shaft 51 and is movably connected to the drive shaft 51.

[0059] Specifically, the reciprocating movement assembly 541 includes a guide frame 5411 movably connected to the frame 31. The guide frame 5411 is fixedly connected to the second connecting plate 542. Two racks 5412 are symmetrically arranged up and down inside the guide frame 5411. A half gear 5413 is arranged between the two racks 5412. The half gear 5413 meshes with one rack 5412 at the same time.

[0060] When the drive shaft 51 needs to swing, the reciprocating movement assembly 541 operates, and the half gear 5413 in the reciprocating movement assembly 541 rotates counterclockwise. When the half gear 5413 meshes with the rack 5412 below the inside of the guide frame 5411, the half gear 5413 drives the guide frame 5411 to move horizontally towards one end through the rack 5412. The guide frame 5411 drives the transmission rod 543 to move through the second connecting plate 542. The transmission rod 543 is movably connected to the drive shaft 51. Therefore, one end of the transmission rod 543 rotates relative to the second connecting plate 542, and the other end of the transmission rod 543 slides relative to the drive shaft 51. At this time, the transmission rod 543 tilts towards one side, and the transmission rod 543 drives the drive shaft 51 to rotate. When the half gear 5413 meshes with the rack 5412 above the inside of the guide frame 5411, the half gear 5413 drives the guide frame 5411 to move horizontally towards the other end through the rack 5412. Therefore, the drive shaft 51 deflects in the direction of movement towards the guide frame 5411. Through the continuous rotation of the half gear 5413, the reciprocating swing of the drive shaft 51 is realized.

The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
