Technical Field

[0001] This utility model relates to the field of mesh belt conveying technology, specifically to an adjustable mesh belt length assembly structure. Background Technology

[0002] A mesh belt furnace is an industrial furnace that uses a high-temperature resistant metal mesh belt as a conveyor belt to heat-treat workpieces in continuous operation. Its working principle involves placing the workpiece evenly on the mesh belt, which is then driven by a motor to slowly pass through the furnace chamber, achieving fully automated heating, heat preservation, and cooling processes under controlled atmosphere and temperature conditions.

[0003] In the prior art, the authorized announcement number CN220624844U discloses a mesh belt furnace feeding device, which includes a support frame, a mesh belt furnace is fixed between two sets of support frames with screws, a feeding port is opened at one end of the mesh belt furnace, a conveying component is installed inside the mesh belt furnace to convey materials, and a uniform feeding mechanism is installed at the top of the conveying component at the end of the feeding port.

[0004] Through the continuous operation of the mesh belt, various materials can be effectively transported into the furnace for processing. However, in actual working environments, the required mesh belt length often varies due to different production needs and equipment layouts. This difference depends not only on the specific dimensions and location of the furnace but also on factors such as the type of material, conveying speed, and working environment conditions. Therefore, an adjustable mesh belt assembly structure is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable assembly structure for the conveyor belt to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable mesh belt assembly structure, including an outer shell, a mesh belt body inside the outer shell, a protective cover fixedly installed on the side wall of the outer shell, a drive roller rotatably installed at one end of the outer shell, and an adjustment mechanism installed at the other end of the outer shell. The adjustment mechanism includes positioning slide rails fixedly installed on both sides of the outer shell and a mounting frame fixedly installed inside the outer shell. Telescopic rods are slidably installed on the positioning slide rails, a crossbeam is fixedly installed between the telescopic rods, a driven roller is rotatably installed at the end of the telescopic rods, a screw jack is fixedly installed on the mounting frame, the output end of the screw jack is connected to the crossbeam, and a tensioning mechanism is installed on the outer shell.

[0007] Preferably, a drive shaft is fixedly installed on the input end of the screw jack, and a crank handle is fixedly installed at the end of the drive shaft.

[0008] Preferably, a bearing is mounted on the housing, and the drive shaft is rotatably mounted on the housing via the bearing.

[0009] Preferably, the telescopic rod is slidably installed on both sides of the housing via a positioning slide rail, the driven roller is movably installed at the other end of the housing via the telescopic rod, and the screw jack is fixedly installed inside the housing via a mounting bracket.

[0010] Preferably, the tensioning mechanism includes turntables rotatably mounted on both sides of the housing, two tensioning rollers rotatably mounted on the edge of the turntables, and the mesh belt body passing through the gap between the tensioning rollers. A reducer is fixedly mounted on one side of the housing, and a bidirectional threaded rod is rotatably mounted on one side of the housing. A lead screw slider is threaded onto the bidirectional threaded rod, and a tensioning spring is connected to the lead screw slider. A bevel gear is fixedly mounted on the output end of the reducer, and a drive shaft is fixedly mounted on the output end of the reducer. Bevel gears are fixedly mounted on the drive shaft, the drive shaft, and the bidirectional threaded rod.

[0011] Preferably, a groove is provided on the side wall of the outer casing, and the lead screw slider is slidably mounted on the side wall of the outer casing through the groove.

[0012] Preferably, the outer casing has rotating grooves on both sides, and the turntable is rotatably mounted on the outer casing through the rotating grooves.

[0013] Preferably, one end of the tension spring is fixedly installed on the lead screw slider, and the other end of the tension spring is fixedly installed on the edge of the turntable. The bevel gear on the drive shaft meshes with the bevel gear on the input end of the reducer, and the bevel gear on the transmission shaft meshes with the bevel gear on the bidirectional threaded rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, after the user turns the crank handle, the drive shaft will drive the screw jack to extend. When the screw jack extends, it will move the crossbeam forward, causing the telescopic rod to extend. After the telescopic rod extends, it will drive the driven roller to move forward, thereby adjusting the running length of the conveyor belt.

[0015] 2. In this application, the tension spring provides tension to the turntable, causing it to twist. After the turntable twists, the tension roller applies tension to the conveyor belt body, achieving tensioning of the conveyor belt body. Furthermore, when the drive shaft rotates, it drives the input end of the reducer to rotate. After the reducer slows down, the drive shaft drives the bidirectional threaded rod to rotate slowly. During the slow rotation of the bidirectional threaded rod, the two screw sliders move closer to each other, shortening the tension length of the tension spring, reducing the tension applied by the tension roller to the conveyor belt body, making the telescopic rod easier to slide out, and reducing the difficulty of adjustment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for an adjustable mesh belt assembly structure, including a shell 1, a mesh belt body 3 inside the shell 1, a protective cover 2 fixedly installed on the side wall of the shell 1, a drive roller 4 rotatably installed at one end of the shell 1, an adjustment mechanism 5 installed at the other end of the shell 1, and a tensioning mechanism 6 installed on the shell 1.

[0020] Specifically, the motor drives the drive roller 4 to rotate, which in turn drives the mesh belt body 3 to move, thereby conveying the material. The tensioning mechanism 6 applies tension to the mesh belt body 3, keeping it in a taut state. The adjustment mechanism 5, used in conjunction with the tensioning mechanism 6, allows users to easily adjust the running length of the mesh belt.

[0021] Example 2: Figure 3 and Figure 4As shown, the adjustment mechanism 5 includes positioning slide rails 503 fixedly installed on both sides of the housing 1 and mounting brackets 506 fixedly installed inside the housing 1. Telescopic rods 502 are slidably installed on the positioning slide rails 503. A crossbeam 504 is fixedly installed between the telescopic rods 502. A driven roller 501 is rotatably installed at the end of the telescopic rods 502. A screw jack 505 is fixedly installed on the mounting bracket 506. The output end of the screw jack 505 is connected to the crossbeam 504. A drive shaft 507 is fixedly installed on the input end of the screw jack 505. A crank handle 508 is fixedly installed at the end of the drive shaft 507. A bearing is installed on the housing 1. The drive shaft 507 is rotatably installed on the housing 1 through the bearing.

[0022] Specifically, when the user rotates the crank handle 508, the drive shaft 507 immediately begins to rotate. This rotation is directly transmitted to the screw jack 505, causing it to extend. During the extension process, the internal mechanical structure of the screw jack 505, through a precise transmission mechanism, drives the crossbeam 504 forward along a preset track. As the crossbeam 504 moves forward, the connected telescopic rod 502 is also pushed and gradually extends outward. Once the telescopic rod 502 is fully extended, the driven roller 501 connected to its front end also moves forward to a new position. This series of interlocking actions ultimately achieves effective adjustment of the conveyor belt's running length, ensuring stable operation and precise control of the equipment under different working conditions.

[0023] Example 3: Figure 3 and Figure 5 As shown, the tensioning mechanism 6 includes a turntable 601 rotatably mounted on both sides of the outer casing 1. Two tensioning rollers 602 are rotatably mounted on the edge of the turntable 601, and the mesh belt body 3 passes through the gap between the tensioning rollers 602. A reducer 607 is fixedly mounted on one side of the outer casing 1, and a bidirectional threaded rod 604 is rotatably mounted on one side of the outer casing 1. A lead screw slider 603 is threaded onto the bidirectional threaded rod 604, and a tensioning spring 605 is connected to the lead screw slider 603. A bevel gear 608 is fixedly mounted on the output end of the reducer 607, and a drive shaft 606 is fixedly mounted on the output end of the reducer 607. Bevel gears 608 are fixedly mounted on the drive shaft 507, the drive shaft 606, and the bidirectional threaded rod 604. A sliding groove is provided on the side wall of the outer casing 1, and the lead screw slider 603 is slidably mounted on the side wall of the outer casing 1 through the sliding groove.

[0024] Specifically, the tension spring 605 applies tension to the turntable 601, causing the turntable 601 to twist. After the turntable 601 twists, the tension roller 602 applies tension to the mesh belt body 3, thereby tensioning the mesh belt body 3.

[0025] Furthermore, when the drive shaft 507 rotates, it drives the input end of the reducer 607 to rotate. After being reduced in speed by the reducer 607, the drive shaft 606 drives the bidirectional threaded rod 604 to rotate slowly. When the bidirectional threaded rod 604 rotates slowly, the two screw sliders 603 will move closer to each other, shortening the tension length of the tension spring 605, reducing the tension applied by the tension roller 602 to the mesh belt body 3, making the telescopic rod 502 easier to slide out, and reducing the difficulty of adjustment.

[0026] Working principle: The motor drives the drive roller 4 to rotate, which in turn drives the mesh belt body 3 to rotate, thereby conveying materials. When the user turns the crank handle 508, the drive shaft 507 drives the screw jack 505 to extend. When the screw jack 505 extends, it drives the crossbeam 504 forward, causing the telescopic rod 502 to extend. After the telescopic rod 502 extends, it drives the driven roller 501 forward, thereby adjusting the running length of the mesh belt. The tension spring 605 provides tension to the turntable 601, causing the turntable 601 to twist. After the turntable 601 twists, the tension roller 602 applies tension to the mesh belt body 3, tightening the mesh belt body 3. Furthermore, when the drive shaft 507 rotates, it will drive the input end of the reducer 607 to rotate. After being reduced by the reducer 607, the transmission shaft 606 will drive the bidirectional threaded rod 604 to rotate slowly. When the bidirectional threaded rod 604 rotates slowly, the two screw sliders 603 will move closer to each other, shortening the tension length of the tension spring 605, reducing the tension that the tension roller 602 will apply to the mesh belt body 3, making the telescopic rod 502 easier to slide out and reducing the difficulty of adjustment.
