Description

Technical Field

[0001] This application relates to the field of conveying equipment technology, and in particular to a mobile material centralized conveying trolley for an extrusion production line. Background Technology

[0002] In extrusion production lines in industries such as plastics, rubber, and food, traditional material conveying methods typically employ fixed pipeline conveying, manual handling, or decentralized feeding systems. Fixed conveying pipelines are difficult to adjust their layout after installation and cannot adapt to the flexible switching requirements of multiple production lines and multiple types of materials. Manual handling or single-point feeding methods lead to production cycle delays, especially during material changes or cleaning, resulting in long downtime.

[0003] A search revealed that CN215742094U discloses a portable mobile filter cart. This portable mobile filter cart facilitates efficient automated filtration through inlet, delivery, and outlet pipes. The filter cartridge, installed inside the filter cylinder, provides excellent filtration and purification, and is easy to disassemble, clean, or replace quickly. Support columns welded to the outside of the filter cylinder provide stable support to the top of the cart's base plate. The structure is simple, safe, and practical. A push rod welded to the top right end of the cart's base plate and wheels located at the bottom outer end of the base plate facilitate direct pushing and sliding, making it widely applicable and reducing the workload for workers. Spring rods and fixing plates welded to the top of the wheels provide cushioning and shock absorption, preventing swaying.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist that need to be improved: Although the above-mentioned device facilitates the transfer and transportation of materials by using a mobile trolley, the material distribution during transportation will be uneven, thereby increasing the difficulty of collection. Furthermore, the above-mentioned device connects the feeding system to the extruder through a rigid pipe, which cannot adapt to the flexible switching requirements of different machines. It also lacks a precise positioning system, which is prone to docking deviations that lead to material leakage. Utility Model Content

[0026] The adjustable docking assembly 6 includes a fixed frame 61, a push cylinder 62, a vertical tube 63, a metal telescopic tube 64, a snap-fit ​​plate 65, and a docking connector 66. The fixed frame 61 is fixedly connected to the top of the conveyor body 1. The top of the push cylinder 62 is fixedly connected to both sides of the snap-fit ​​plate 65. The bottom of the metal telescopic tube 64 is fixedly connected to one end of the vertical tube 63. The snap-fit ​​plate 65 snaps onto the outside of the metal telescopic tube 64. The docking connector 66 is fixedly connected to the top of the metal telescopic tube 64.

[0027] The anti-accumulation component 7 includes a toothed outer bracket 71, a sliding bracket 72, a servo motor 73, a locking gear 74, a stepper motor 75, and a sweeping roller 76. The toothed outer bracket 71 is fixedly connected to the outside of the centralized material box 5. The sliding bracket 72 is slidably connected to the outside of the toothed outer bracket 71, and the protruding end of the sliding bracket 72 extends into the interior of the centralized material box 5 and is slidably connected to the top inner wall of the centralized material box 5.

[0028] The bottom of the cone-shaped guide table 4 is also screwed with a vibration motor 8.

[0029] An inclined filter plate 9 and a slag frame 10 are also provided on the outer side of the conical guide platform 4. The inclined filter plate 9 is fixedly connected to the bottom outer side of the conical guide platform 4, and the slag frame 10 is located below the inclined filter plate 9 and is used to receive impurities that roll down under high-frequency vibration.

The top of the discharge pipe 11 extends into the interior of the centralized material box 5 and is tightly fitted to the top inner wall of the centralized material box 5.

[0031] The top of the centralized material box 5 is also fixedly connected to a limiting frame 13, which is slidably sleeved on the outside of the sliding bracket 72 and is used to limit the movement path of the sliding bracket 72.

[0032] The general process of using the mobile material centralized conveying trolley for the extrusion production line in this application embodiment is as follows: Laser scanner 2 starts working, emitting laser pulses and receiving reflected signals to scan the workshop environment in real time. Based on a preset path planning algorithm, the system controls the conveyor trolley 1 to automatically travel to the target extruder station. When approaching the target position, laser scanner 2 accurately identifies the coordinates of the extruder's discharge port, and conveyor trolley 1 makes fine adjustments to its positioning. During docking adjustment, the push cylinder 62 of the adjustable docking assembly 6 is activated, pushing the clamping plate 65 to move vertically. The metal telescopic tube 64 automatically adjusts its extension length and tilt angle based on the laser positioning data, achieving precise docking of the connector 66 with the extruder discharge pipe, forming a sealed connection channel. During material sorting, the material is conveyed through vertical pipe 63 to the side-groove guide box 3. Vibration motor 8 starts, driving the conical guide platform 4 to generate high-frequency micro-vibration. The material is evenly dispersed and falls along the conical surface. Light impurities are screened through inclined filter plate 9 to the slag frame 10, while clean material is further dusted through the lateral airflow channel of the side-groove guide box 3 before entering the centralized material box 5. The material pump 12 conveys the material to the centralized material box 5 through the discharge pipe 11. At this time, the servo motor 73 drives the locking gear 74 to rotate, which drives the sliding bracket 72 to move along the toothed outer bracket 71. The stepper motor 75 drives the sweeping roller 76 to rotate, so as to spread the material in the centralized material box 5 evenly. The limit frame 13 ensures that the sliding bracket 72 moves smoothly within the predetermined range, and completes the material spreading operation of the entire box, avoiding local accumulation that leads to dampness and mold.

[0033] The beneficial technical effects of the mobile material centralized conveying trolley used in the extrusion production line according to the embodiments of this application are roughly as follows: This device achieves automated driving and precise stopping of the conveyor trolley through laser pulse ranging and path recognition, avoiding human error. The cylinder 62 drives the clamping plate 65 to rise and fall. The metal telescopic tube 64 can be freely adjusted in length and angle. The connector 66 adapts to different diameter feed pipes, allowing the device to accommodate extruder interfaces with varying heights and inclination angles. The conical guide plate 4 promotes material flow through high-frequency vibration, while the inclined filter plate 9 screens impurities to the slag frame 10. The combined action of vibration and the filter plate separates clumps or foreign objects, improving raw material cleanliness and reducing the risk of extruder blockage. The spiral motion of the sweeping roller 76 evenly spreads the material, preventing localized accumulation that could lead to dampness and mold, facilitating subsequent feeding.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. 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.
