Description

Technical Field

[0001] This application relates to the field of conveying devices, and more specifically, to an electric roller conveyor high and low station connection device. Background Technology

[0002] An electric roller conveyor is a new type of drive device that integrates both the motor and the reducer inside the roller body. It is mainly used in stationary and mobile belt conveyors, replacing traditional electric motors. The reducer is a separate drive unit located outside the drive roller. As a power unit for belt conveyors, electric roller conveyors are widely used in mining, metallurgy, chemical, coal, building materials, power, grain, and transportation industries.

[0003] Existing electric roller conveyor systems often employ fixed slope designs or passive transition structures to cope with angle changes, making it difficult to adapt to the flexible connection requirements of multiple workstations and angles. When the conveyor belt needs to transition from a horizontal section to an inclined section, the items are prone to lateral slippage due to the force of gravity, resulting in a deviation in the conveying path. Therefore, an electric roller conveyor high and low workstation connection device is needed to help solve this problem. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of existing technologies by providing a high-low station connection device for electric roller conveyors. This addresses the problem that existing electric roller conveyor systems often employ fixed slope designs or passive transition structures when dealing with angle changes, making it difficult to adapt to the flexible connection requirements of multiple stations and angles. Furthermore, when the conveyor belt needs to transition from a horizontal section to an inclined section, the items are prone to lateral slippage due to the force of gravity, leading to deviation of the conveying path.

[0006] To achieve the above objectives, this application provides the following technical solution: A high-low position connection device for electric roller conveyor includes: a mounting frame, on which electric rollers are rotatably arranged at equal intervals, a servo motor for driving the electric rollers to rotate is installed on the side of the mounting frame, and a high-low position switching device for assisting in switching the height of items is installed in the middle section of the mounting frame. The high / low position switching device includes a mounting base installed at the bottom of the mounting frame. The mounting base has a cavity inside, and a connecting plate is slidably arranged in the cavity. A support base protrudes from the top of the connecting plate and is located between the two electric rolling cylinders. A ball bearing is rotatably arranged at the top of the support base. A movable cavity is provided inside the support base, and a movable component that drives the ball bearing to rotate is installed in the movable cavity. An electric push rod that drives the height adjustment of the connecting plate is installed at the bottom of the mounting base.

[0007] Furthermore, a plurality of balls are provided, and the plurality of balls are arranged in a rectangular array on the top of the support base.

[0008] Furthermore, the moving component includes a conveyor roller rotatably disposed within the moving cavity, a moving belt wound around the conveyor roller, a rotating motor installed inside the support base, a grooved wheel installed on the side of one of the conveyor rollers, a grooved wheel installed at the front end of the shaft of the rotating motor, and the two grooved wheels being connected by a transmission belt.

[0009] Furthermore, guide rods are symmetrically installed on the mounting base, and the top of the guide rods is fixed at the bottom of the connecting plate.

[0010] Furthermore, a first mounting clip is symmetrically mounted on the outer side of the mounting frame, a clamping plate is mounted on the first mounting clip, and a base frame is fixed between the first mounting clip and the clamping plate.

[0011] Furthermore, the four base frames are connected and fixed together by I-shaped connecting frames.

[0012] Furthermore, a leveling knob is installed at the bottom of the base frame, and the base frame and the leveling knob are threaded together.

[0013] The beneficial effects of this application are as follows: by setting a height switching device, the ball bearings set on the top of the support base are distributed in a rectangular array, which effectively reduces the frictional resistance between the item and the support surface. Combined with the active drive function of the moving component, a smooth transition is achieved when the item is switched between high and low work positions, avoiding jamming or damage caused by height difference, improving conveying efficiency. The precise lifting control of the electric push rod enables the device to adapt to the connection needs of work positions at different heights, enhancing the versatility of the equipment.

[0014] The combination structure of the first mounting clip and the clamping plate, together with the I-shaped connecting frame, forms a high-strength frame system, which effectively disperses the stress generated during the operation of the electric rolling drum and the high-low position switching device, extends the service life of the equipment, and also allows for convenient and effective adjustment of the overall height of the mounting frame during operation.

[0022] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1-4 As shown, this utility model provides an electric roller conveyor high and low position connection device, including: a mounting frame 1, on which electric rollers 3 are rotatably arranged at equal intervals, a servo motor 4 for driving the electric rollers 3 to rotate is installed on the side of the mounting frame 1, a first mounting clamp 5 is symmetrically installed on the outer side of the mounting frame 1, a clamping plate 6 is installed on the first mounting clamp 5, a base frame 2 is fixed between the first mounting clamp 5 and the clamping plate 6, and the four base frames 2 are connected and fixed by an I-shaped connecting frame 7. The combination structure of the first mounting clamp 5 and the clamping plate 6, together with the I-shaped connecting frame 7, forms a high-strength frame system, which effectively disperses the stress generated by the electric rollers 3 and the high and low position switching device 9 during operation, extends the service life of the equipment, and also allows for convenient and effective adjustment of the overall height of the mounting frame 1 during operation.

[0024] The base frame 2 is equipped with a leveling knob 8 at its bottom. The base frame 2 and the leveling knob 8 are threaded together. By using the leveling knob 8, the overall levelness of the device can be effectively adjusted during operation, thereby ensuring that the device will not shake during operation.

[0025] The mounting frame 1 is equipped with a height-low position switching device 9 for assisting in switching the height of items at its middle section. The height-low position switching device 9 includes a mounting base 10 installed at the bottom of the mounting frame 1. The mounting base 10 has a cavity inside, and a connecting plate is slidably disposed within the cavity. A support base 13 protrudes from the top of the connecting plate and is located between two electric rolling cylinders 3. A ball bearing 14 is rotatably disposed at the top of the support base 13. The characteristic feature is that several balls bearing 14 are arranged in a rectangular array on the top of the support base 13. The support 13 has a movable cavity inside, and a movable component 15 that drives the ball bearing 14 to rotate is installed inside the movable cavity. The movable component 15 includes a conveyor roller 16 that is rotatably installed inside the movable cavity. A movable belt 17 is wound around the conveyor roller 16. A rotary motor 18 is installed inside the support 13. A grooved wheel 19 is installed on the side of one of the conveyor rollers 16. A grooved wheel 19 is installed at the front end of the shaft of the rotary motor 18. The two grooved wheels 19 are connected by a transmission belt 20. An electric push rod 11 that drives the height adjustment of the connecting plate is installed at the bottom of the mounting base 10.

[0026] With the height switching device 9, the ball bearings 14 on the top of the support base 13 are designed in a rectangular array to effectively reduce the frictional resistance between the item and the support surface. Combined with the active drive function of the moving component 15, the item can smoothly transition between high and low work positions, avoiding jamming or damage caused by height differences and improving conveying efficiency. The precise lifting control of the electric push rod 11 allows the device to adapt to the connection needs of work positions at different heights, enhancing the versatility of the equipment.

[0027] Furthermore, guide rods 12 are symmetrically installed on the mounting base 10. The top of the guide rods 12 is fixed to the bottom of the connecting plate. The guide rods 12 ensure that the connecting plate can only move vertically up and down during operation.

[0028] Working principle: This electric roller conveyor is a high-low station connection device. This electric roller conveyor high and low station connection device realizes the basic conveying of items through the electric rollers 3 equidistantly arranged on the mounting frame 1. The electric rollers 3 are driven by the servo motor 4 to rotate synchronously, completing the directional movement of items on the conveyor line.

[0029] The high / low position switching device 9 set in the middle section of the mounting frame 1 achieves workstation switching through the following process: the electric push rod 11 pushes the connecting plate in the mounting base 10 to slide vertically, driving the support base 13 to rise and fall vertically, so that the balls 14 distributed in a rectangular array on the top of the support base 13 contact the bottom of the item. At this time, the rotating motor 18 is started to drive the conveyor roller 16 to rotate through the grooved wheel 19 and the transmission belt 20, which in turn drives the moving belt 17 to rotate in conjunction with the balls 14, forming an auxiliary pushing force, so that the item can smoothly cross different height workstations under the dual drive of the electric rolling drum 3 and the balls 14.

[0030] The first mounting clip 5 on the outside of the mounting frame 1 cooperates with the clamping plate 6 to fix the base frame 2. The four base frames 2 form a stable frame structure through the I-shaped connecting frame 7. The leveling knob 8 at the bottom of the base frame 2 achieves fine adjustment of the device's level through threaded engagement, ensuring that each component is subjected to uniform force during the conveying process. The guide rod 12 passes through the mounting base 10 and is fixed to the bottom of the connecting plate, forming a vertical lifting guide constraint to prevent the support base 13 from shifting.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
