Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a roller device for a plate-type feeder. Background Art

[0002] In modern material conveying systems, apron feeders are widely used in mining, metallurgy, building materials and other fields as a basic and key component. It relies on the movement of the chain plate to achieve continuous conveying of large or bulk materials. During the operation of the chain plate, the roller device plays a vital supporting and guiding role. However, the existing roller device has certain limitations and urgently needs technical innovation to improve its integrity.

[0003] In the prior art, the rollers at the ends of the plate feeder are often installed in a fixed position and lack an effective tension adjustment mechanism. As the chain plate is used and aged, its tension will gradually decrease, causing the chain plate to jump, deviate or even fall off during movement, which not only affects the conveying efficiency, but also may cause material loss or mechanical failure, increasing maintenance costs and downtime. Therefore, we propose a plate feeder roller device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] The present application provides a plate feeder roller device, which is mainly used to solve the problem that the rollers at the end of the plate feeder in the prior art are often installed in a fixed position and lack an effective tension adjustment mechanism. As the chain plate is used and aged, its tension will gradually decrease, causing the chain plate to jump, deviate or even fall off during movement, which not only affects the conveying efficiency, but also may cause material loss or mechanical failure, increase maintenance costs and downtime, and provide the following technical solutions, which will be combined with Figure 1-Figure 3 Make a detailed description:

[0024] A plate feeder roller 5 device, comprising:

[0025] A mounting base 1 and an apron feeder body 2, wherein the apron feeder body 2 is arranged on one side of the top of the mounting base 1, and a conveying chain plate 201 is arranged on the apron feeder body 2 for transmission;

[0026] The fixing plate 3 is symmetrically fixed on the end side of the mounting seat 1, and the inner side surface of the fixing plate 3 is fixed with a mounting box 4;

[0027] The roller 5 is movably arranged between the two mounting boxes 4 and inserted into the conveying chain plate 201;

[0028] The adjusting mechanism 6 is used to adjust the front and rear positions of the roller 5. The adjusting mechanism 6 includes a screw rod 601 rotatably connected between the inner walls of the installation box 4. The surface of the screw rod 601 is threadedly connected with a slider 602. The slider 602 is slidably connected to the inner wall of the installation box 4. The roller 5 is arranged between the sliders 602.

[0029] The driving mechanism 7 is arranged at the end side of the installation box 4 and is used to drive the screw rod 601 to rotate.

[0030] The working principle of the plate feeder roller 5 device is mainly to adjust the position of the roller 5 through the adjustment mechanism 6 to change the tension of the conveying chain plate 201. When the tension of the conveying chain plate 201 decreases due to use and aging, the driving mechanism 7 can be used to drive the screw 601 to rotate and drive the slider 602 to move in the installation box 4, thereby realizing precise adjustment of the position of the roller 5 to change the tension of the conveying chain plate 201, so that the conveying chain plate 201 maintains an appropriate tension state to ensure its normal operation. The device has a simple structure and is easy to implement. It can be widely used in various plate feeders and has high practical value.

[0031] like Figure 3As shown, in some embodiments, a rotating rod 603 is rotatably connected between the sliders 602 via a bearing, and the roller 5 is fixed at the middle of the rotating rod 603. More specifically, due to the rotating design of the rotating rod 603, the roller 5 can rotate freely when the conveying chain 201 moves, which helps to maintain the smoothness of the chain movement. When the chain moves on the roller 5, the rotation of the roller 5 can reduce the resistance, so that the chain can pass more smoothly and reduce the possibility of jumping and deviation.

[0032] like Figure 2 As shown, in some embodiments, a strip channel 401 is constructed on one side of the mounting box 4 close to the conveying chain plate 201, and a rotating rod 603 slides and penetrates inside the strip channel 401. More specifically, the strip channel 401 provides a precise guide path for the rotating rod 603, so that when the position of the roller 5 is adjusted, the movement of the rotating rod 603 will not deviate from the predetermined trajectory, thereby ensuring the correct alignment of the roller 5 and stable support of the conveying chain plate 201.

[0033] like Figure 3 As shown, in some embodiments, the driving mechanism 7 includes an extension plate 701 fixedly mounted on the end side of the mounting box 4, an adjusting rod 702 is rotatably connected between the extension plates 701, a driven bevel gear 703 is fixedly mounted at one end of the screw 601 located outside the mounting box 4, and active bevel gears 704 are fixedly mounted on both sides of the surface of the adjusting rod 702, and the active bevel gear 704 is meshed with the driven bevel gear 703. More specifically, the specific working principle of the driving mechanism 7 is to rotate the adjusting rod 702, utilize the active bevel gear 704 to drive the driven bevel gear 703 to rotate, and then drive the screw 601 to rotate.

[0034] like Figure 3 As shown, in some embodiments, one end of the adjustment rod 702 passes through the extension plate 701 and is connected to a knob 705. More specifically, the design of the knob 705 allows the operator to easily turn the adjustment rod 702 to adjust the position of the roller 5, thereby maintaining the appropriate tension of the conveyor chain plate 201.

[0035] like Figure 1 As shown, in some embodiments, a guide block 8 is provided in the middle of one side of the mounting seat 1 close to the fixed plate 3. The guide block 8 is triangular and its upper end is connected with the conveying chain plate 201. More specifically, the triangular guide block 8 helps to smoothly guide the material from the conveying chain plate 201 to the next stage. The triangular design helps to reduce the blockage of the material during the conveying process. The material can move along the inclined surface of the triangular guide block 8 with the help of its own gravity to reduce the accumulation of the material at the end of the conveying chain plate 201, thereby ensuring the smooth operation of the plate feeder.

[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
