Description

Technical Field

[0001] This utility model relates to the field of vacuum feeding machine technology, and in particular to an automatic loading trolley. Background Technology

[0002] A vacuum feeder is an automated device that uses the principle of vacuum negative pressure to transport powdery and granular materials. Its core components include a vacuum generation system, a filtration and separation system, a hopper, and a control system. During operation, a vacuum pump or vacuum generator creates a negative pressure airflow within a closed pipeline, drawing material from the starting point into the hopper. After gas-solid separation via a filter element, the material falls into downstream equipment under gravity or backflushing. This technology is widely used in the pharmaceutical, food, and chemical industries, effectively achieving closed-loop conveying in the production process, significantly reducing dust leakage and cross-contamination, and improving the automation level of material transfer and the cleanliness of the operating environment. It is an indispensable key process equipment in modern industry.

[0003] The loading trolley is a device that mounts the material cylinder of a vacuum feeder onto a trolley, allowing for more flexible movement of the vacuum feeder. However, this type of loading trolley has the following drawbacks: the height of the material cylinder cannot be adjusted, and the distance between the material cylinder and the trolley cannot be changed, making it inconvenient to adapt to processing equipment of different heights and widths, thus exhibiting certain limitations. Therefore, further improvements are needed. To this end, we propose an automatic loading trolley. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an automatic loading trolley.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic loading trolley, comprising a base plate, a negative pressure pump, and a material cylinder. The negative pressure pump is fixed to the upper surface of the base plate, and an air extraction pipe is connected between the material cylinder and the negative pressure pump. A suction pipe is fixed to the inlet of the material cylinder. Two through slots are opened on the side of the base plate near the material cylinder, and a support component is installed inside the through slots. A vertical guide rail groove is fixed to the upper surface of the base plate, and a slider is slidably connected inside the guide rail groove. A telescopic component is fixedly connected to the slider and the outer wall of the material cylinder. A servo motor is installed at the top of the guide rail groove, and a lead screw is fixed to the bottom output end of the servo motor. The lead screw passes through the slider and is threadedly connected to the slider. A controller is installed on the upper surface of the negative pressure pump.

[0006] Furthermore, a handle is fixed to one side of the upper surface of the base plate, and multiple casters are fixed to the lower surface of the base plate.

[0007] Furthermore, the support assembly includes a first electric telescopic rod fixed inside the through groove, the telescopic end of the first electric telescopic rod being fixed with a support wheel, and the first electric telescopic rod being electrically connected to the controller.

[0008] Furthermore, a guide rod is fixed inside the guide rail groove, the guide rod passes through the slider and is slidably connected to the slider, and the servo motor is electrically connected to the controller.

[0009] Furthermore, a laser distance sensor is fixed to the bottom wall of the guide rail groove, and the top of the laser distance sensor faces the lower surface of the slider. The laser distance sensor is electrically connected to the controller.

[0010] Furthermore, the telescopic assembly includes a support tube fixed to the surface of the slider, a support rod slidably connected inside the support tube, one end of the support rod located outside the support tube being fixedly connected to the material cylinder, a second electric telescopic rod being fixedly fixed to the surface of the support tube, the telescopic end of the second electric telescopic rod being fixedly connected to the upper surface of the support rod, and the second electric telescopic rod being electrically connected to the controller.

[0011] The beneficial effects of this utility model are:

[0012] 1. When in use, this utility model includes a base plate, a negative pressure pump, a material cylinder, an air extraction pipe, a support assembly, a guide rail groove, a slider, a telescopic assembly, and a servo motor. When the loading trolley is in use, the slider can be driven by the servo motor to move up and down along the guide rail groove, or the material cylinder can be driven to move horizontally by the telescopic assembly, thereby adjusting the height and horizontal position of the material cylinder to adapt to processing equipment of different heights.

[0013] 2. When this utility model is in use, a base plate and a support assembly are provided. When the telescopic assembly drives the material cylinder to move away from the base plate, the center of gravity moves away from the base plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, an automatic feeding trolley is disclosed, comprising a base plate 1, a negative pressure pump 2, and a material cylinder 3. The negative pressure pump 2 is fixed to the upper surface of the base plate 1. An air extraction pipe 4 is connected between the material cylinder 3 and the negative pressure pump 2. A suction pipe 5 is fixed to the inlet of the material cylinder 3. Two through slots 101 are opened on the side of the base plate 1 near the material cylinder 3, and a support component 6 is installed inside the through slots 101. A vertical guide rail groove 7 is fixed to the upper surface of the base plate 1, and a slider 8 is slidably connected inside the guide rail groove 7. A telescopic component 9 is fixedly connected to the slider 8 and the outer wall of the material cylinder 3. A servo motor 10 is installed at the top of the guide rail groove 7. A lead screw 11 is fixed to the bottom output end of the servo motor 10. The lead screw 11 passes through the slider 8 and is threadedly connected to the slider 8. A controller 14 is installed on the upper surface of the negative pressure pump 2.

[0022] In this embodiment, both the negative pressure pump 2 and the material cylinder 3 are existing technologies. After the negative pressure pump 2 is started, a vacuum can be drawn into the inside of the material cylinder 3, thereby using the suction pipe 5 to draw the powder into the inside of the material cylinder 3. Then the valve at the bottom of the material cylinder 3 is opened, allowing the powder to fall into the processing equipment. The specific working principle will not be described in detail here.

[0023] A handle 16 is fixed to one side of the upper surface of the base plate 1, and multiple casters 15 are fixed to the lower surface of the base plate 1.

[0024] The caster wheel 15 is a locking caster wheel 15. The trolley can be pushed to the side of the processing equipment by the handle 16, and then the caster wheel 15 can be locked to fix the trolley.

[0025] The support assembly 6 includes a first electric telescopic rod 61 fixed inside the through groove 101. The telescopic end of the first electric telescopic rod 61 is fixed with a support wheel 62. The first electric telescopic rod 61 is electrically connected to the controller 14.

[0026] The controller 14 controls the extension and retraction of the first electric telescopic rod 61, which in turn moves the support wheel 62, causing the support wheel 62 to move closer to or further away from the base plate 1. When the support wheel 62 moves away from the base plate 1, it increases the stability of the entire vehicle; when the support wheel 62 moves closer to the base plate 1, it reduces the space occupied at the bottom of the vehicle. The extension and retraction of the first electric telescopic rod 61 is matched with the extension and retraction of the telescopic assembly 9.

[0027] A guide rod 12 is fixed inside the guide rail groove 7. The guide rod 12 passes through the slider 8 and is slidably connected to the slider 8. The servo motor 10 is electrically connected to the controller 14.

[0028] After the servo motor 10 is controlled to rotate forward or backward by the controller 14, the servo motor 10 drives the lead screw 11 to rotate, and the lead screw 11 then drives the slider 8 to rise and fall along the guide rail groove 7 and the guide rod 12, thereby driving the telescopic component 9 and the material cylinder 3 to rise and fall as a whole.

[0029] A laser distance sensor 13 is fixed to the bottom wall of the guide rail groove 7, and the top of the laser distance sensor 13 faces the lower surface of the slider 8. The laser distance sensor 13 is electrically connected to the controller 14.

[0030] During the lifting and lowering of slider 8, laser distance sensor 13 continuously monitors the height of slider 8, and this information is fed back to controller 14. Therefore, when adjusting the height of cylinder 3, the specified height can be directly input through controller 14. Under the feedback of laser distance sensor 13, servo motor 10 drives slider 8 to lift and lower. After reaching the specified height, servo motor 10 stops rotating.

[0031] The telescopic assembly 9 includes a support tube 91 fixed to the surface of the slider 8, a support rod 92 slidably connected inside the support tube 91, one end of the support rod 92 located outside the support tube 91 being fixedly connected to the material cylinder 3, a second electric telescopic rod 93 fixed to the surface of the support tube 91, the telescopic end of the second electric telescopic rod 93 being fixedly connected to the upper surface of the support rod 92, and the second electric telescopic rod 93 being electrically connected to the controller 14.

[0032] If the processing equipment is wide, even after the base plate 1 is close to the processing equipment, the material cylinder 3 still cannot be positioned horizontally above the feed inlet of the processing equipment. In this case, the controller 14 can control the extension of the second electric telescopic rod 93, thereby driving the support rod 92 to extend from the support tube 91, so that the material cylinder 3 moves away from the base plate 1 until the material cylinder 3 is located at the top feed inlet of the processing equipment. During this process, the center of gravity will deviate from the base plate 1. Therefore, while controlling the extension and retraction of the second electric telescopic rod 93, the controller 14 will simultaneously drive the extension and retraction of the first electric telescopic rod 61, thereby ensuring the stability of the entire trolley.

[0033] In this embodiment, the controller 14 can be a Siemens SIMATIC KP1200 series (HMI+PLC integrated machine) KP1212 Basic PN controller with screen. The first electric telescopic rod 61, the second electric telescopic rod 93, and the servo motor 10 are all controlled by the controller 14. The model of the laser distance sensor 13 can be selected according to cost. The electrical components, the electrical connection lines with the controller 14 and the control program mentioned above are existing technologies and will not be described in detail here.

[0034] Working principle: The operator first pushes the trolley with handle 16 and moves it to the vicinity of the target processing equipment using casters 15, then locks the casters 15 to achieve positioning. The target height of the material cylinder 3 is set by the controller 14, and the servo motor 10 starts and drives the lead screw 11 to rotate, causing the slider 8 to slide vertically along the guide rod 12 and the guide rail groove 7; during this process, the laser distance sensor 13 monitors the height of the slider 8 in real time and feeds it back to the controller 14 until the material cylinder 3 reaches the preset position.

[0035] If the material cylinder 3 is not horizontally aligned with the equipment inlet, the controller 14 activates the second electric telescopic rod 93 to push the support rod 92 out of the support pipe 91, so that the material cylinder 3 extends horizontally to directly above the inlet. At the same time, the controller 14 synchronously controls the first electric telescopic rod 61 to extend the support wheel 62 to balance the center of gravity. After positioning is completed, the negative pressure pump 2 is activated to evacuate the material cylinder 3 through the suction pipe 4. External materials are sucked into the material cylinder 3 through the suction pipe 5. Then, the valve at the bottom of the material cylinder 3 is opened, and the material falls into the processing equipment under gravity, completing the automated loading process.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
