Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a conveyor driving device. Background Art

[0002] The existing conveyor drive device cannot work properly when the material gets entangled with the conveying spiral blades during operation. At the same time, the rotational stress of the motor increases, causing overload. If there is no coupling, the motor will be damaged. If there is a coupling, the existing coupling lacks a warning device, which makes it impossible for the staff to know the equipment status in the first time.

[0003] Therefore, the present application provides a conveyor drive device to meet the needs. Utility Model Content

[0004] The purpose of this application is to provide a conveyor drive device, which aims to solve the problem that when the motor of the existing drive device is overloaded and cannot work normally, the staff cannot be notified immediately.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example: Reference Figure 1-7 The conveyor driving device shown includes a conveyor body 1 and a driving device 2, and the conveyor body 1 and the driving device 2 are connected.

[0027] Driving device 2: The driving shaft of the motor 3 is connected to the coupling 5 through the reducer 4. A prompt component is provided next to the coupling 5. When the equipment is overloaded, the sliding part provided on the coupling 5 contacts the prompt component, thereby causing the prompt component to disconnect the power supply of the motor 3 and activate the alarm so that the staff can be aware of the situation here.

[0028] Coupling 5: The No. 1 cover 6 and the No. 2 cover 7 are connected by bolts and nuts, and the No. 1 groove 61 and the No. 2 groove 71 are respectively provided on the opposite surfaces of the No. 1 cover 6 and the No. 2 cover 7. The No. 1 groove 61 and the No. 2 groove 71 are both connected to the outside world. The driven disc 8 and the driving disc 9 are rotatably connected in the No. 1 groove 61 and the No. 2 groove 71 respectively, and the end surface of the driven disc 8 is provided with six groups of hemispherical limit grooves 81 arranged in an annular array; the end surface of the driving disc 9 is provided with a telescopic groove 91 adapted to the limit groove 81, and the limit head 10 is slidably connected in the telescopic groove 91, and the limit head 10 The outward end is adapted to the limit slot 81, and a spring 12 that can push the limit head 10 outward at any time is pressed between the limit head 10 and the telescopic slot 91; the driven disc 8 is connected to the conveyor body 1, and the driving disc 9 is connected to the reducer 4. Through the above structure, disconnection protection can be performed when overload occurs to avoid damage to the motor; in order to further reduce the economic losses caused by overload, a sliding part is provided in the No. 2 cover 7, and the sliding part is connected to the prompt component (when overloaded, the sliding part cooperates with the prompt component to stop the motor and prompt the staff's operation).

[0029] Sliding member: An annular ring groove 72 is provided at the end of the second groove 71, and an annular drive ring 13 is provided on the outer wall of the drive disk 9. The design of the ring groove 72 provides a sliding space for the drive ring 13, and in order to achieve the overload of the coupling 5, the drive ring 13 can be pushed to slide in the ring groove 72; therefore, a card groove 92 connected to the outside is provided on the inner wall of the telescopic groove 91, and a card block 11 is provided on the outer wall of the limit head 10. The card block 11 slides in the card groove 92 and protrudes from the card groove 92, and its end slides in the ring groove 72 (and at the drive The ring 13 contacts), so when it is overloaded, the limit head 10 slides in the telescopic groove 91, squeezing the spring 12 while the block 11 pushes the drive ring 13 to move backward, and in order to enable the drive ring 13 to have the ability to automatically reset, an auxiliary mechanism is provided on the second cover 7; a slide groove 73 connected to the outside is provided at the top of the annular groove 72, and a protrusion is provided on the outer wall of the drive ring 13, and the protrusion slides in the slide groove 73, so that the moving drive ring 13 contacts the prompt component through the protrusion extending out of the slide groove 73 to perform prompt and power-off operations.

[0030] Auxiliary mechanism: An auxiliary groove 74 connecting the annular groove 72 is provided on the right end face of the No. 2 cover 7, and the auxiliary groove 74 is in a "convex" shape. The T-shaped auxiliary rod 15 slides in the auxiliary groove 74, one end of which contacts the drive ring 13, and the other end cooperates with the bolt on the auxiliary groove 74. An auxiliary spring 16 is pressed between the two, which provides an inward thrust to the drive ring 13 at all times so that it can perform a reset operation after the overload is completed.

[0031] Prompt component: A U-shaped bracket is provided next to the coupling 5, and a contact switch 14 is provided on the bracket, which is electrically connected to the alarm and the power supply of the motor 3. The button and the protrusion of the contact switch 14 are at the same height. When overloaded, the drive ring 13 moves and touches the contact switch 14 through the protrusion to perform the alarm and shutdown tasks.

[0032] The working principle of this utility model is as follows: by starting the motor 3 of the driving device 2 to make it work, the driving shaft of the motor 3 passes through the reducer 4, so that the torque provided by it is uniformly transmitted to the conveyor body 1 through the coupling 5 to achieve the working purpose.

[0033] When an overload occurs during use, the driving disk 9 in the second cover 7 and the limiting head 10 on the driving disk 9 slide out of the limiting groove 81 of the driven disk 8 in the first cover 6. In this process, the limiting head 10 squeezes the spring 12, and the clamping block 11 on the limiting head 10 slides in the clamping groove 92 and the annular groove 72, pushing the driving ring 13, so that the driving ring 13 slides on the driving disk 9, and pushes the auxiliary rod 15, squeezing the auxiliary spring 16 in the auxiliary groove 74, and the convex head on the outer wall of the driving ring 13 slides in the sliding groove 73 and contacts the contact switch 14 on the bracket. The overload situation here is notified through the contact switch 14, and the motor 3 is powered off.

[0034] When the maintenance work is completed, the auxiliary rod 15 and the auxiliary spring 16 cooperate to automatically reset the drive ring 13 and release the contact state with the contact switch 14 so that it can be used normally.
