Description

Technical Field

[0001] This utility model relates to the field of belt conveyor adjustment technology, specifically a belt conveyor that is easy to adjust. Background Technology

[0002] Belt conveyors, also known as belt conveyors, are continuous conveying equipment widely used in industrial production, logistics and other fields. Belt conveyors play a significant role, and in the logistics industry, they are an indispensable piece of equipment used for sorting, handling and loading / unloading goods. They can handle large quantities of goods quickly and efficiently. However, in actual use, belt conveyors often need to be height adjusted because different working environments and production needs have different requirements for the height of belt conveyors.

[0003] Existing adjustable belt conveyors have a support leg assembly fixedly connected to the conveyor frame. This assembly includes a fixed plate, an angle adjustment plate, an upper support leg, and a lower support leg. The upper support leg is vertically connected to the bottom of the fixed plate and has a long slotted hole vertically on it. The lower support leg has several threaded holes at its connection end with the upper support leg. Adjusting bolts are used to pass through the long slotted hole and the threaded holes to fix the two together. By changing the position of the bolts in the long slotted hole and the threaded holes, the relative position of the upper support leg and the lower support leg can be adjusted, thereby achieving the adjustment of the belt conveyor height.

[0004] Existing belt conveyors of this type that are easy to adjust mostly rely on manual operation for outrigger adjustment. Height adjustment is achieved by changing the position of bolts in long slots or different threaded holes. This method makes it difficult to accurately control the height of the belt conveyor and is prone to over- or under-adjustment. During the adjustment process, it is necessary to manually operate the bolts and other components on the outriggers one by one. For longer or larger belt conveyors, there may be multiple outriggers that need to be adjusted, which is cumbersome and time-consuming. Therefore, we propose a belt conveyor that is easy to adjust. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an easily adjustable belt conveyor that can effectively reduce swaying and deviation during the adjustment process, ensure the stability of the belt conveyor when adjusting the height, eliminate the need for manual operation of each adjustment component, greatly improve the degree of automation of adjustment, and effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an easily adjustable belt conveyor, comprising a support frame, wherein rotating shafts are rotatably connected to the front and rear inner walls of the support frame, a base is fixedly connected between the two rotating shafts, and transmission rollers are rotatably connected between the front and rear inner walls of the base, the two transmission rollers are connected by a transmission belt, and a height adjustment mechanism is also included.

[0007] Height adjustment mechanism: It includes rectangular grooves, rotating columns, connecting rods, sliding grooves, and top rods. Rectangular grooves are respectively opened on the upper surface of the support frame. Rotating columns are rotatably connected to the inner wall of the rectangular grooves away from the center of the support frame. Connecting rods are fixedly sleeved on the outside of the rotating columns. Sliding grooves are respectively opened on the front and rear inner walls of the base. Top rods are fixedly connected between the two connecting rods. The outside of the top rods is slidably connected to the inner wall of the sliding groove. This can effectively reduce shaking and offset during the adjustment process, ensure the stability of the belt conveyor when adjusting the height, and eliminate the need for manual operation of each adjustment component, greatly improving the automation level of adjustment.

[0008] Furthermore, a microcontroller is provided on the front side of the support frame. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0009] Furthermore, the height adjustment mechanism also includes sprocket one, sprocket two, and a chain. A dual-axis motor is fixedly connected to the bottom end of the support frame. Sprocket two is fixedly mounted on the end of the output shaft of the dual-axis motor away from the center of the support frame, and sprocket one is fixedly mounted on the end of the rotating column near the center of the support frame. Sprocket one and sprocket two on the same side are connected by chain drive. The input end of the dual-axis motor is electrically connected to the output end of the microcontroller to realize adjustment drive.

[0010] Furthermore, the height adjustment mechanism also includes a locking assembly, which includes a groove, a telescopic rod, a support plate, a protrusion, and a spring. The bottom wall of the slide groove is provided with a groove, and the bottom wall of the groove is provided with a telescopic rod. The top ends of two telescopic rods located inside the same groove are fixedly connected to the lower surface of a support plate. The support plate is slidably connected to the inside of the groove on the same side. The upper surface of the support plate is provided with evenly distributed protrusions, and the right side of the protrusions is an arc surface. The springs are respectively sleeved on the outside of the telescopic rods, and the springs are located between the bottom wall of the groove and the lower surface of the support plate to achieve locking after adjustment.

[0011] Furthermore, the locking assembly also includes an electric push rod. The bottom wall of the groove is provided with an electric push rod. The top end of the telescopic end of the electric push rod is fixedly connected to the middle of the lower surface of the support plate inside the same groove. The input end of the electric push rod is electrically connected to the output end of the microcontroller to provide a drive to cancel the locking of the push rod.

[0012] Furthermore, a motor is provided on the front side of the base, and the rear end of the motor's output shaft is fixedly connected to the front end of the transmission roller on the left side. A clearance groove corresponding to the motor is provided on the upper surface of the support frame, and the input end of the motor is electrically connected to the output end of the microcontroller to realize transmission drive.

[0013] Furthermore, support rollers are rotatably connected between the front and rear inner walls of the base, and the outer top ends of the support rollers are in contact with the transmission belt to provide transmission support.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This easily adjustable belt conveyor has the following advantages:

[0015] The dual-axis motor drives the second sprocket to rotate, which in turn drives the first sprocket to rotate via chain transmission. The rotating column then drives the connecting rod to rotate, causing the top rod between the two connecting rods to slide inside the groove in the base. This allows for height adjustment of the base without requiring operators to change the position of bolts in the long slot or different threaded holes. It enables precise control of the conveyor height, reducing the possibility of over- or under-adjustment, and effectively preventing the conveyor from swaying or shifting during adjustment.

The input end of the motor 9 is electrically connected to the output end of the microcontroller 6. The support rollers 10 are rotatably connected between the front and rear inner walls of the base 3. The outer top ends of the support rollers 10 are in contact with the transmission belt 5. When the belt conveyor is needed for work, the support frame 1 is first placed in the designated position. Through the control of the microcontroller 6, the motor 9 starts to run. The output shaft will drive the transmission roller 4 to start running. Through the transmission of the conveyor belt 5, the transmission roller 4 on the right side also starts to rotate, thereby conveying the items.

[0024] Height adjustment mechanism 7: It includes a rectangular groove 71, a rotating column 72, a connecting rod 73, a sliding groove 74, and a top rod 75. Rectangular grooves 71 are respectively opened on the upper surface of the support frame 1. A rotating column 72 is rotatably connected to the inner wall of the rectangular groove 71 on the side away from the center of the support frame 1. A connecting rod 73 is fixedly sleeved on the outside of the rotating column 72. Sliding grooves 74 are respectively opened on the front and rear inner walls of the base 3. A top rod 75 is fixedly connected between the two connecting rods 73. The outside of the top rod 75 is slidably connected to the inner wall of the sliding groove 74. The height adjustment mechanism 7 also includes a first sprocket 76, a second sprocket 77, and a chain 78. A dual-axis motor 8 is fixedly connected to the bottom end of the support frame 1. A second sprocket 77 is fixedly sleeved on the end of the output shaft of the dual-axis motor 8 away from the center of the support frame 1. The rotating column 72 is close to... One end of the support frame 1 near the center is fixedly fitted with a sprocket 76. The sprocket 76 and sprocket 77 on the same side are connected by a chain 78. The input end of the dual-axis motor 8 is electrically connected to the output end of the microcontroller 6. The height adjustment mechanism 7 also includes a locking assembly 79, which includes a groove 791, a telescopic rod 792, a support plate 793, a protrusion 794, and a spring 795. The bottom wall of the slide groove 74 is provided with grooves 791, and the bottom wall of the grooves 791 is provided with telescopic rods 792. The top ends of the two telescopic rods 792 located inside the same groove 791 are fixedly connected to the lower surface of a support plate 793. The support plates 793 are slidably connected to the inside of the grooves 791 on the same side. The upper surface of the support plates 793 is provided with evenly distributed... The fabric protrusion 794 has a right side that is an arc surface. Springs 795 are respectively sleeved on the outside of the telescopic rod 792. The springs 795 are located between the bottom wall of the groove 791 and the lower surface of the support plate 793. The locking assembly 79 also includes an electric push rod 796. The bottom wall of the groove 791 is provided with an electric push rod 796. The top end of the telescopic end of the electric push rod 796 is fixedly connected to the middle of the lower surface of the support plate 793 inside the same groove 791. The input end of the electric push rod 796 is electrically connected to the output end of the microcontroller 6. When the belt conveyor needs to adjust the height, the dual-axis motor 8 starts to run through the control of the microcontroller 6. The output shaft will drive the externally fixed sprocket 77 to start rotating, which is transmitted through the chain 78. The sprocket 76 drives the rotating column 72 to rotate inside the rectangular groove 71, which in turn causes the two connecting rods 73 to drive the push rod 75 to slide to the left inside the slide groove 74. This causes the base 3 to rotate inside the support frame 1 under the support of the rotating shaft 2. When the push rod 75 slides inside the slide groove 74, its outer surface contacts the protrusion 794, causing the protrusion 794 to push down the support plate 793, and the spring 795 to contract. When the push rod 75 slides past the protrusion 794, the spring 795 causes the support plate 793 to rebound, limiting the push rod 75 and preventing it from sliding inside the slide groove 74 during operation. When the conveyor belt needs to be returned to its initial position after use, the electric push rod 796 starts operating under the control of the microcontroller 6.The telescopic end pulls the support plate 793 downwards inside the groove 791, removing the limiting effect of the protrusion 794 on the push rod 75. The dual-axis motor 8 then reverses, causing the connecting rod 73 to drive the push rod 75 to slide to the right inside the slide groove 74, causing the belt conveyor to fall into the support frame 1.

[0025] The working principle of the easily adjustable belt conveyor provided by this utility model is as follows: When the belt conveyor is needed for work, the support frame 1 is first placed in the designated position. Under the control of the microcontroller 6, the motor 9 starts running, and the output shaft drives the transmission roller 4 to start running. Through the transmission of the conveyor belt 5, the right-side transmission roller 4 also starts to rotate, thus conveying the items. When the belt conveyor needs height adjustment, under the control of the microcontroller 6, the dual-shaft motor 8 starts running, and the output shaft drives the externally fixed sprocket 77 to start rotating. Through the transmission of the chain 78, the sprocket 76 drives the rotating column 72 to start rotating inside the rectangular groove 71, thereby causing the two connecting rods 73 to drive the top rod 75 to slide to the left inside the sliding groove 74, so that the base 3, supported by the rotating shaft 2, is supported by the support frame 1. When the top rod 75 slides inside the slide groove 74, and its outer side contacts the protrusion 794, the protrusion 794 causes the support plate 793 to press down, and the spring 795 contracts. When the top rod 75 slides past the protrusion 794, the spring 795 causes the support plate 793 to rebound, so that the protrusion 794 limits the top rod 75 and prevents the top rod 75 from sliding inside the slide groove 74 when the belt conveyor is working. When the belt conveyor needs to be returned to its initial position after use, the electric push rod 796 starts to operate through the control of the microcontroller 6. The telescopic end pulls the support plate 793 down inside the groove 791, canceling the limit of the protrusion 794 on the top rod 75. The dual-axis motor 8 starts to reverse, so that the connecting rod 73 drives the top rod 75 to slide to the right inside the slide groove 74, so that the belt conveyor falls into the support frame 1.

[0026] It is worth noting that the microcontroller 6 disclosed in the above embodiments can be a PI C18F4550, the dual-axis motor 8 can be an 86BYGH118 dual-axis motor, and the motor 9 can be a YS8024. The microcontroller 6 controls the operation of the dual-axis motor 8 and the motor 9 using methods commonly used in the prior art.
