Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a cutting roller loading and unloading trolley. Background Technology

[0002] Figure 1 The detachable fiber chopped strand cutter roller shown is a core component in the fiber chopped strand industry. Its function is to achieve continuous chopped strand cutting of fibers through the relative rotation of the blades and the rubber roller. The cutter roller consists of a roller shaft, a blade mounting roller, a fixed end cap, and multiple blades, which are mounted on precision radial grooves on the outer circumferential wall of the blade mounting roller. Under high-speed operation, the blades will gradually wear down, requiring periodic disassembly and replacement to ensure the length accuracy and cut surface quality of the chopped fibers.

[0003] Currently, the replacement of blades on the aforementioned cutter rollers is mostly done manually, which presents the following problems: ① Manual operation cannot precisely control the consistency of the circumferential installation position and axial arrangement of the blades. Even slight deviations in installation can lead to uneven chopped lengths, fiber fraying, or rough cuts, severely affecting the quality of the chopped cuts. The blade edge needs to protrude a specific distance from the outer surface of the blade mounting section (usually with strict tolerance requirements). Manual installation and adjustment make it difficult to ensure consistency in the protrusion among multiple blades, easily leading to cumulative errors. ② The disassembly and assembly process of the cutter roller is cumbersome, requiring multiple steps such as sequentially removing the end cap, taking out the old blade, cleaning the blade groove, installing the new blade, and tightening the end cap. Each maintenance session is time-consuming, severely impacting the overall utilization rate of the equipment. ③ The blades themselves are sharp, and the cutter roller is relatively heavy. Manual operation carries a high risk of scratches and impacts, and the roller has poor stability during handling, making it prone to accidental slippage.

[0004] To improve the automation level of cutter roller maintenance and reduce labor costs and operational risks, the industry is working to develop dedicated automatic blade changing equipment. However, the effective operation of such automated equipment highly depends on a stable and reliable cutter roller conveying and storage system. Commonly used material racks or flatbed carts in workshops cannot meet the requirements; they lack specialized designs for the special structure and precise positioning needs of cutter rollers, making it difficult to provide a stable and repeatable gripping and placement reference for robotic arms during loading and unloading.

[0005] Therefore, there is an urgent need for a dedicated front-end and rear-end material handling and temporary storage device. This device not only needs to achieve safe transfer of the cutter roller between the maintenance station and the main machine, but more importantly, it needs to provide reliable spatial positioning and attitude maintenance for the cutter roller, so as to ensure that the robot can achieve repeatable positioning accuracy when grasping and placing the cutter roller, and provide reliable material support and technical guarantee for a series of precision operations such as automatic disassembly and assembly and blade replacement.

[0008] Preferably, the stop is a front stop groove disposed at the front end of the base plate and a buffer anti-collision block installed in the front stop groove, and the buffer anti-collision block is made of engineering plastic.

[0009] Preferably, at least one positioning block is fixedly provided on the mobile frame, and the positioning block has a positioning hole; the side groove is provided with a positioning pin that cooperates with the positioning hole, and the positioning pin is connected to a pneumatic drive device; when the trolley assembly moves to the preset working position, the pneumatic drive device drives the positioning pin to insert into the positioning hole.

[0010] Preferably, the adjacent support plates are staggered in the height direction, and all the support plates spatially form a load-bearing structure for accommodating two layers of cutter rollers.

Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0022] In the embodiments, such as Figures 2-5As shown, a cutting roller loading and unloading trolley includes: a track assembly 1, fixedly installed on the ground; a trolley assembly 2, disposed on the track assembly 1 and movable along its length; the trolley assembly 2 includes a movable frame 2.1, the bottom of the movable frame 2.1 is provided with casters 2.2 with braking mechanisms, and the top is provided with a support platform 2.3; the support platform 2.3 is provided with a plurality of grouped support plates 2.4, and the upper surface of the support plates 2.4 is provided with an arc-shaped groove 2.5 for supporting the roller shaft 3.1 of the cutting roller 3; the track assembly 1 includes a base plate 1.1, side retaining grooves 1.2 fixedly installed on both sides of the base plate 1.1, and a stop member disposed at the front end of the base plate 1.1; the side retaining grooves 1.2 are provided with a plurality of guide wheels 1.3, and the sides of the movable frame 2.1 are fixed with guide plates 2.6 that roll with the guide wheels 1.3. The track assembly 1 is fixedly installed on the ground, providing a stable movement path for the trolley assembly 2. The trolley assembly 2 is flexibly moved and fixed via casters 2.2 with brake mechanisms at the bottom of the moving frame 2.1, improving the convenience and safety of transportation. The grouped support plates 2.4 and their arc-shaped grooves 2.5 on the bearing platform 2.3 are specifically designed to support the roller shaft 3.1, preventing the cutter roller 3 from rolling or slipping during transportation and ensuring the stability of the cutter roller's posture. The guide wheels 1.3 on the side grooves 1.2 of the track assembly 1 roll in cooperation with the guide plates 2.6 on both sides of the moving frame 2.1, making the trolley move smoothly and reducing shaking. The stop at the front end of the base plate 1.1 limits the movement range of the trolley assembly 2, avoiding the risk of collision caused by excessive movement. The overall design realizes the safe transportation of the cutter roller between the maintenance station and the main unit, and provides a reliable positioning reference for automated operation.

[0023] In the embodiments, such as Figures 2-5 As shown, the stop components are a front stop groove 1.4 located at the front end of the base plate 1.1 and a buffer anti-collision block 1.5 installed on the front stop groove 1.4. The buffer anti-collision block 1.5 is made of engineering plastic. The front stop groove 1.4 provides a structured stop device, enhancing the strength and durability of the front end of the track assembly 1. The engineering plastic material of the buffer anti-collision block 1.5 has good buffering performance and wear resistance, effectively absorbing the impact energy when the trolley assembly 2 moves, reducing collision noise and component damage, and further improving the safety and service life of the trolley.

[0024] In the embodiments, such as Figures 2-5As shown, at least one positioning block 2.7 is fixedly installed on the mobile frame 2.1, and the positioning block 2.7 has a positioning hole 2.8. The side groove 1.2 is provided with a positioning pin 1.6 that cooperates with the positioning hole 2.8. The positioning pin 1.6 is connected to a pneumatic drive device 1.7. When the trolley assembly 2 moves to the preset working position, the pneumatic drive device 1.7 drives the positioning pin 1.6 to insert into the positioning hole 2.8 to achieve positioning and locking of the trolley assembly 2. The cooperation between the positioning pin 1.6 and the positioning hole 2.8 achieves precise positioning and locking of the trolley assembly 2, eliminates human operation errors, ensures the repeatability of the positioning accuracy of the cutter roller 3 during the loading and unloading process, provides a stable and reliable reference for the robot to grasp and place the cutter roller 3, and improves the efficiency and reliability of automated operation.

[0025] In the embodiments, such as Figures 2-5 As shown, adjacent support plates 2.4 are staggered in the height direction, and all support plates 2.4 form a load-bearing structure in space to accommodate two layers of cutter rollers 3. Through space optimization design, the temporary storage capacity of the trolley is increased, allowing more cutter rollers 3 to be carried at the same time, thus improving space utilization and operating efficiency. The staggered arrangement avoids interference between cutter rollers 3, ensuring the stability and safety of the placement of cutter rollers 3, and is suitable for high-density storage and transfer needs.

[0026] In the embodiments, such as Figures 2-5 As shown, the spacing between each set of support plates 2.4 is adapted to the positioning step structure on the roller shaft 3.1 of the cutter roller 3 to be supported. By customizing the spacing, the support plates 2.4 can accurately match the structure of the roller shaft 3.1, providing a more stable support and preventing the cutter roller 3 from axially moving or tilting during transportation. This ensures the posture maintenance and positioning accuracy of the cutter roller 3, and improves the accuracy and safety of loading and unloading.

[0027] In the embodiments, such as Figures 2-5 As shown, the guide wheel 1.3 is vertically mounted on the side retaining groove 1.2 via an axle, and the movable frame 2.1 is supported on the guide wheel 1.3 by the guide plates 2.6 on both sides. The vertically mounted guide wheel 1.3 and the guide plates 2.6 form a stable rolling support structure, reducing frictional resistance and wear during trolley movement and ensuring smooth movement of the trolley on the track. This design enhances the overall rigidity and guiding accuracy, prevents the trolley assembly 2 from deviating or jamming, and improves the reliability and durability of the transfer.

[0028] In the embodiments, such as Figures 2-5 As shown, a guide ramp 1.8 is provided at one end of the entrance of the side retaining groove 1.2. The guide ramp 1.8 provides guidance, enabling the trolley assembly 2 to enter the track assembly 1 easily and accurately, reducing alignment difficulty and operation time, preventing the trolley from colliding or being damaged when entering the track, and improving the convenience and safety of use.

[0029] Obviously, the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Other obvious variations or modifications derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
