Description

Technical Field

[0001] This utility model relates to the technical field of hardware component processing equipment, and more specifically to a material conveyor belt. Background Technology

[0002] Some existing workpieces need to be taken out from the previous processing equipment and transported to the subsequent processing equipment during processing. In order to reduce manual labor and improve efficiency; It sets up a belt conveyor between two processing equipment, so that the workpieces processed in one process can be placed on the belt conveyor and transported to the subsequent processing equipment for manual processing; However, in existing belt conveyors, the conveyor belt lacks a limiting mechanism, which causes it to shift back and forth during operation. This results in the edge of the conveyor belt colliding with the transverse beam and wearing down, reducing its service life and affecting its conveying efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a material conveyor belt, in which the annular protrusions on the conveyor belt cooperate with and insert into the guide grooves of the horizontal support plate, so that the conveyor belt will not shift back and forth, ensuring normal conveying and good conveying effect.

[0004] The solution of this utility model to the aforementioned technical problem is: A material conveyor belt includes a main frame, which includes two transverse beams at the front and rear. A transmission roller extending from the front and rear is provided between the left and right parts of the two transverse beams. The two ends of the transmission roller are connected to the two transverse beams by bearings. The connecting shaft at one end of the transmission roller extends out of the corresponding transverse beam and is fixed with a transmission sprocket. Vertical support legs are fixed to the left and right sides of the bottom surface of the two transverse beams. Motor frames are fixed to the side walls of the corresponding vertical support legs. The drive motor is fixed to the motor frame. A drive sprocket is fixed to the output shaft of the drive motor. The chain is tensioned on the drive sprocket and the transmission sprocket. The two drive rollers are tensioned with conveyor belts; Multiple horizontal support plates are fixed between the two transverse beams, and the top surface of the horizontal support plates is in close contact with or close to the bottom surface of the upper belt body of the conveyor belt. The top surface of the horizontal support plate is formed with guide grooves that extend to the left and right and protrude from the left and right ends of the horizontal support plate. The inner walls of the left and right sides of the conveyor belt are each formed with annular raised strips, and the upper part of the annular raised strips is inserted into the corresponding guide grooves.

[0005] Two horizontal support plates are fixed between the two transverse beams, and an intermediate support roller is provided between the two horizontal support plates. The two ends of the rotating shaft movably connected in the middle of the intermediate support roller extend out of the front and rear ends of the intermediate support roller and are installed on the bent support block fixed on the inner side wall of the middle of the two transverse beams.

[0006] The top surface of the vertical part of the two bent support blocks has a slot extending downward. The two ends of the shaft of the middle support roller are inserted into the corresponding slots, and its bottom surface presses against the bottom surface of the slot. The top surface of the middle support roller presses against the bottom surface of the middle part of the upper belt body of the conveyor belt. The front and rear outer walls of the transmission roller are both formed with annular grooves, and the annular protrusions are inserted into the corresponding annular grooves.

[0007] Bottom support rollers are provided on the left and right sides of the bottom surface of the two transverse beams. The front and rear ends of the bottom support rollers are installed on the lower support seats, which are fixed on the bottom surface of the corresponding transverse beams. The bottom surface of the lower belt body of the conveyor belt presses against the top surface of the two bottom support rollers.

[0008] The outstanding effect of this utility model is: Its conveyor belt has annular raised strips that fit into and insert into the guide grooves of the horizontal support plate, ensuring that the conveyor belt will not shift back and forth, thus guaranteeing normal conveying and good conveying effect.

[0009] Similarly, annular grooves are formed on the front and rear outer walls of the drive roller body, and annular protrusions are inserted into the corresponding annular grooves, which further ensures the normal conveying of the conveyor belt. Meanwhile, its limiting rod can limit the height of the workpieces conveyed on the conveyor belt, preventing the workpieces from being stacked and affecting subsequent processing and material handling.

A transmission roller 11 extending forward and backward is provided between the left and right parts of the two transverse beams. The two ends of the transmission roller 11 are connected to the two transverse beams by bearings. The connecting shaft of one end of the transmission roller 11 extends out of the corresponding transverse beam and is fixed with a transmission sprocket 12. Vertical support legs are fixed to the left and right sides of the bottom surface of the two transverse beams. A transverse connecting beam is fixed between each pair of adjacent vertical support legs. A motor frame is fixed to the side wall of one of the corresponding vertical support legs. The drive motor 13 is fixed to the motor frame. A drive sprocket 131 is fixed to the output shaft of the drive motor 13. The chain 1 is tensioned on the drive sprocket 131 and the transmission sprocket 12. The two drive rollers 11 are tensioned with conveyor belts 14; Multiple horizontal support plates 20 are fixed between the two transverse beams, and the top surface of the horizontal support plates 20 is in close contact with or close to the bottom surface of the upper belt of the conveyor belt 14. The bottom surfaces of the front and rear parts of the horizontal support plate 20 are both formed with downwardly extending bent edges 21, which are closely attached to the inner side of the corresponding transverse beam and fixedly connected by bolts. The top surface of the horizontal support plate 20 is formed with guide grooves 22 that extend to the left and right ends of the horizontal support plate 20 at both the front and rear. The inner walls of the left and right sides of the conveyor belt 14 are each formed with annular protrusions 141, and the upper part of the annular protrusions 141 is inserted into the corresponding guide grooves 22.

[0012] The front and rear outer walls of the transmission roller 11 are both formed with annular grooves, and the annular protrusions 141 are inserted into the corresponding annular grooves.

[0013] The above structure enables the conveyor belt 14 to have a limiting function during operation, preventing it from shifting forward or backward and ensuring its normal operation; Furthermore, the bottom surface of the horizontal support plate 20 is fixed with a plurality of front-to-back extending reinforcing ribs 23.

[0014] Furthermore, two horizontal support plates 20 are fixed between the two transverse beams, and an intermediate support roller 30 is provided between the two horizontal support plates 20. The two ends of the rotating shaft movably connected to the middle of the intermediate support roller 30 extend out of the front and rear ends of the intermediate support roller 30 and are installed on the bent support block 31 fixed on the inner side wall of the middle of the two transverse beams. The intermediate support roller 30 is located between two annular protrusions 141.

[0015] Furthermore, the top surface of the vertical part of the two bending support blocks 31 is formed with a downward extending slot, and the two ends of the rotating shaft of the intermediate support roller 30 are inserted into the corresponding slots, with its bottom surface pressing against the bottom surface of the slot, and the top surface of the intermediate support roller 30 pressing against the bottom surface of the middle part of the upper belt body of the conveyor belt 14. Furthermore, the bottom support rollers 16 are provided on the left and right sides of the bottom surface of the two transverse beams. The front and rear ends of the bottom support rollers 16 are mounted on the lower support seats 17. The lower support seats 17 are fixed on the bottom surface of the corresponding transverse beams. The bottom surface of the lower belt body of the conveyor belt 14 presses against the top surface of the two bottom support rollers 16.

[0016] The lower part of the conveyor belt 14 is supported by the bottom support roller 16.

[0017] Furthermore, a protective cover 18 is fixed on the outer wall of the transverse beam on the side where the motor frame is installed, and the chain 1, drive sprocket 131 and transmission sprocket 12 are located in the protective cover 18.

[0018] Furthermore, a side vertical support frame 40 is fixed to the top surface of the middle of both transverse beams. A vertical screw 41 is provided in the middle of the side vertical support frame 40. The top and bottom ends of the vertical screw 41 are movably connected to the top and bottom blocks of the side vertical support frame 40 through bearings. An adjusting motor 42 is fixed in the middle of the top surface of the top block of the side vertical support frame 40. The output shaft of the adjusting motor 42 is a spline shaft that is inserted into the spline hole at the top of the vertical screw 41. The top of the vertical screw 41 is fixed in the inner ring of the bearing fixed in the through hole in the middle of the top block of the side vertical support frame 40. The adjusting motor 42 drives the vertical screw 41 to rotate. The lifting block 43 is screwed onto the vertical screw 41. The two ends of the limiting rod 44 are fixedly connected to the two lifting blocks 43. A vertical baffle is fixed on the left side wall of the limiting rod 44, and the top of the vertical baffle extends upward.

[0019] Furthermore, self-lubricating plates 45 are fixed on both the left and right sides of the lifting block 43, and the outer side wall of the self-lubricating plate 45 is in close contact with the inner side wall of the vertical side beam of the corresponding side vertical support frame 40.

[0020] In this embodiment, the workpiece can be placed on the conveyor belt 14 and transported by the operation of the conveyor belt 14. Generally, after the previous equipment has finished processing, there will be a pile of workpieces placed on the top surface of the upper belt body of the conveyor belt 14. They will be stacked, which will affect the subsequent material handling. Therefore, by operating two adjusting motors 42 simultaneously (the adjusting motors 42 are servo motors), the vertical baffle is lowered so that its bottom reaches the required height. When the workpiece is transported on the conveyor belt 14, the part that is higher than the bottom of the vertical baffle will be blocked by the vertical baffle and fall to the left side (the workpiece is transported from left to right). This ensures that the height of the workpiece entering the right end is lower than the bottom of the vertical baffle (generally, stacked workpieces will be higher than the bottom of the vertical baffle). This ensures that the workpieces entering the right end are basically not stacked, making it convenient for the subsequent processing equipment to handle the material.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
