[0002] Reciprocating cloth machine is often used in the feeding system of sintering process or pelletizing process in the steel industry, and single-point unloading will cause material granularity segregation due to the large size of the feeding bin, and after the material is distributed to the trolley, the granularity is uneven, the air permeability is quite different, which affects the sinter quality, increases the return ore amount and increases the sintering system cost. Therefore, using the reciprocating cloth machine to uniformly distribute the material in the large bin is an important technical measure to realize low carbon, emission reduction and clean production.

DETAILED DESCRIPTION

[0027] In order to facilitate the understanding of the present application, the present application will be described more fully below, and preferred embodiments of the present application will be given. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application herein is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0029] Embodiment:

[0030] Referring to Figures 1-6 The present embodiment provides a pin gear transmission type reciprocating cloth machine, which comprises a frame body, a cloth trolley and a belt. The frame body is provided with a guide rail, and the cloth trolley is slidingly connected to the guide rail. The cloth trolley comprises a trolley frame, a first change direction roller, a second change direction roller and a driving mechanism for driving the trolley frame to reciprocate along the guide rail. The first change direction roller is rotatably arranged at one end of the trolley frame, and the second change direction roller is rotatably arranged below the trolley frame and away from the first change direction roller. The first end of the driving mechanism is connected to the top of the trolley frame, and the second end of the driving mechanism is connected to the frame body. The reciprocating cloth machine further comprises a driving roller, a third change direction roller and a fourth change direction roller, which are all rotatably connected to the frame body. The belt is sequentially wound around the driving roller, the third change direction roller, the first change direction roller, the second change direction roller and the fourth change direction roller. The belt between the third change direction roller and the first change direction roller is a first section belt, which is arranged parallel to the guide rail. The belt between the second change direction roller and the fourth change direction roller is a second section belt, which is arranged parallel to the guide rail.

[0031] Specifically, the pin-tooth transmission type reciprocating distributing machine is arranged above the stock bin needing to be distributed, and the stock bin is within the moving range of the distributing trolley discharge port, so that the distributing trolley can be moved to each position of the stock bin, and thus the material output by the distributing trolley can uniformly cover the entire stock bin.

[0032] It can be known that the material above the belt is discharged from the discharge port of the distributing trolley in the moving process of the belt driven by the driving roller. Figure 1 and Figure 2 It can be known that when the distributing trolley moves, the length of the first section of the belt becomes shorter while the length of the second section of the belt becomes longer, and the length of the first section of the belt becomes shorter by exactly the length of the second section of the belt, that is, the tightness of the belt does not change when the distributing trolley moves on the track, so that the belt is not easy to slip during the movement of the distributing trolley, so that the belt can always run stably and uniformly, and when the distributing trolley moves uniformly on the track, the position of the discharge port on the distributing trolley also moves uniformly with the distributing trolley, so that the material can be uniformly laid in the stock bin below the distributing trolley.

[0033] Further, a fifth redirection roller is rotationally connected to the frame and arranged below the third redirection roller.

[0034] The fifth redirection roller changes the direction of the belt, so that the belts on both sides of the driving roller are substantially parallel, facilitating the arrangement of the position of the driving roller, and being conducive to ensuring that the driving roller has a large enough belt wrap angle to prevent the belt from slipping.

[0035] Further, a tensioning mechanism is arranged between the driving roller and the fourth redirection roller, and the tensioning mechanism includes a first tensioning roller and a second tensioning roller, both of which are rotationally connected to the frame, and the belt passes the first tensioning roller and the second tensioning roller in sequence.

[0036] It can be known that the first tensioning roller and the second tensioning roller of the tensioning mechanism tension the belt, and the setting of the tensioning mechanism prevents the belt from loosening and slipping during operation, so that the belt can run smoothly.

[0037] Further, the distributing trolley further includes a plurality of support rollers, which are rotationally connected to the frame in sequence and at intervals, and the top of the plurality of support rollers is flush with the top of the first redirection roller.

[0038] The material distribution trolley is horizontally arranged on the frame, that is, the material distribution trolley moves horizontally during movement, and the belt above the material distribution trolley also moves horizontally with the material distribution trolley. The belt needs to carry materials, and the belt is supported by the supporting rollers to prevent the belt from being in dry friction with the frame of the material distribution trolley under the pressure of the materials, and the supporting rollers and the belt are in rolling friction during operation, thereby reducing the resistance of the belt during operation.

[0039] Further, the material distribution trolley further comprises a supporting roller, which is rotationally connected to the lower part of the frame and located between the first and second redirecting rollers, and the belt is supported on the supporting roller.

[0040] It can be known that the supporting roller supports the belt, reduces the tension of the belt caused by its own weight, and improves the service life of the belt.

[0041] Further, the driving mechanism comprises a pin gear rack, a pin gear and a driving source, the pin gear rack is fixedly connected to the top of the material distribution trolley, the pin gear is rotationally connected to the frame, the pin gear is engaged with the pin gear rack, and the driving source is fixedly connected to the frame and coaxially fixedly connected to the pin gear at the output end.

[0042] It can be known that the driving source drives the pin gear to rotate to drive the pin gear rack to move, thereby driving the frame to slide along the slide rail on the frame. By driving the pin gear to rotate forward or reversely, the pin gear drives the pin gear rack and the frame to reciprocatingly slide along the slide rail. The engagement between the pin gear and the pin gear rack has low requirements for the environment and can adapt to high-temperature and high-dust environments. The pin gear and the pin gear rack do not need to be lubricated by grease and oil, so dust is not easy to adhere to the pin gear and the pin gear rack in the environment with dust, thereby reducing the wear of the pin gear and the pin gear rack and improving the service life.

[0043] Notably, the driving mechanism is arranged at the middle position of the frame of the material distribution trolley, thereby improving the stability of the driving mechanism in driving the frame to move.

[0044] Further, the pin gear rack comprises a plurality of cylindrical pins, two vertical plates and a bottom plate, the bottom plate is fixedly installed on the top of the frame by bolts, the bottom plate is arranged in parallel with the guide rail, the two vertical plates are fixedly connected to the bottom plate by welding, and the two vertical plates are arranged in parallel with each other, the cylindrical pins are arranged in sequence and horizontally penetrate through the two vertical plates, the plurality of cylindrical pins are arranged at equal intervals along the length direction of the vertical plate, and the interval between the centers of two adjacent cylindrical pins is equal to the length of the arc line of the pitch circle between two adjacent teeth on the pin gear.

[0045] It can be known that during rotation of the pin gear, each tooth groove of the pin gear is engaged with the cylindrical pin on the pin gear rack in sequence, and such engagement enables the pin gear to conveniently drive the pin gear rack to move. The production precision of the pin gear and the pin gear rack is lower than that of gears, thereby reducing the manufacturing cost.

[0046] Further, the pin rack further comprises pin sleeves, the pin sleeves are coaxially sleeved on the cylindrical pins, the pin sleeves are arranged in plurality, and the pin sleeves are arranged in one-to-one correspondence with the cylindrical pins.

[0047] It can be known that, without the pin sleeve, when the pin gear meshes with the cylindrical pin of the pin rack, the contact between the pin gear and the cylindrical pin is linear contact, and sliding friction occurs between the pin gear and the cylindrical pin during the meshing process, and the friction of the linear contact easily causes wear between the cylindrical pin and the pin gear, thereby affecting the service life of the cylindrical pin and the pin gear. After the pin sleeve is sleeved on the cylindrical pin, the contact between the pin sleeve and the cylindrical pin is surface contact, and the rotation of the pin sleeve relative to the cylindrical pin can reduce friction and wear, thereby improving the service life of the cylindrical pin. When the pin gear meshes with the cylindrical pin, the pin sleeve contacts the pin gear, and the pin sleeve rotates relative to the cylindrical pin. No sliding friction occurs between the pin sleeve and the pin gear, so the wear of the pin gear is also reduced, and the service life of the driving mechanism is improved.

[0048] Further, the inner surface of the pin sleeve is provided with a self-lubricating plating layer, and the pin sleeve is rotatably connected through the self-lubricating plating layer. It can be known that the self-lubricating plating layer reduces the friction between the pin sleeve and the cylindrical pin, reduces the wear between the pin sleeve and the cylindrical pin, and improves the service life of the cylindrical pin and the pin sleeve.

[0049] Further, the driving source comprises a motor and a speed reducer, the speed reducer is installed on the frame body, the output end of the motor is connected with the input end of the speed reducer, and the output end of the speed reducer is coaxially and fixedly connected with the pin gear. Specifically, the speed reducer reduces the rotation speed and increases the torque, the motor drives the speed reducer to rotate, and the speed reducer drives the pin gear to rotate through the motor, the pin gear drives the pin rack to move along the length direction of the pin rack, and the pin rack reciprocatingly moves through the forward or reverse rotation of the motor. Because the pin rack is fixedly connected to the vehicle frame, the vehicle frame reciprocatingly moves with the pin rack.

[0050] Further, a dust cover is arranged on the vehicle frame and below the pin rack. Through the arrangement of the dust cover, the dust generated by the material on the belt is prevented from moving upward and adhering to the pin gear or the pin rack.

[0051] Further, the first end of the track is arranged with a first limiting block, and the second end of the track is arranged with a second limiting block. Through the arrangement of the limiting blocks, the material cart is prevented from deviating from the track and causing an accident during movement.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
