In the process of non-woven fabric processing, a transport truck is needed to transport them, so we propose a transport truck that is easy to load and unload.

[0003] According to the existing patent publication number: CN219687357U, a handling device for non-woven fabric production includes a vehicle body bottom plate and a cylindrical rod. The upper surface of the vehicle body bottom plate is provided with a movable component, and the movable component includes a roller storage frame, a rolling wheel 1 and a placement frame. The inner side of the roller storage frame is connected to a rolling wheel 1 in a rolling manner, and the cylindrical rod is fastened to the upper side of the inner bottom wall of the placement frame by bolts. The handling device for non-woven fabric production avoids the phenomenon of the placement frame shaking left and right during the movement of the handling device by setting the cylindrical rod, but the following defects are exposed during use:

[0004] 1. After the transporter transfers the non-woven materials to the appropriate location, when unloading the non-woven materials, the staff needs to take out the non-woven materials inside one by one. The non-woven materials at the bottom are lower, which requires the staff to bend down to reach the materials, which is inconvenient for loading and unloading.

[0005] 2. Secondly, the internal space of the transport vehicle is usually fixed. When there are a lot of non-woven materials to be transported, the staff will need to increase the number of times of transporting, thereby increasing the labor intensity of the staff. Utility Model Content

[0025] The embodiment of the utility model provides a transport vehicle that is convenient for loading and unloading materials, and has the following beneficial effects:

[0026] 1. By setting a servo motor, a load-bearing plate and a ball bearing, the servo motor drives the load-bearing plate to move up and down in the outer frame through the threaded shaft, and controls the forward and reverse rotation of the servo motor. If loading, first rotate forward to drive the load-bearing plate to move up, and then slowly reverse to drive the load-bearing plate to move down as the non-woven material is placed. If unloading, then slowly rotate forward to drive the load-bearing plate to move up as the non-woven material above is taken, so as to facilitate the non-woven material at the bottom, thereby facilitating the loading and unloading work of the staff. At the same time, the load-bearing plate moves up and down stably with the cooperation of the ball bearing and the ball bearing groove.

[0027] 2. By setting up the extension plate, fixings and connecting holes, when there are a lot of non-woven materials to be transported, the staff can take out the fixings and pull the extension plate upwards. After the limiting plate limits it to the appropriate position, the fixings can be connected to the corresponding connecting holes in turn to complete the fixation of the extension plate, thereby increasing the longitudinal area of ​​the outer frame, so that more non-woven materials can be placed at one time, so as to reduce the number of times the staff carry them back and forth, thereby reducing the labor intensity of the staff.

DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0035] Example: Figure 1-Figure 4As shown, a transport vehicle convenient for loading and unloading materials comprises an outer frame 1 and columns 3 at both ends thereof, which are used to install and fix various components so as to facilitate the cooperation of various components. The staff can use the control panel 4 to operate the transport vehicle. The carrying plate 16 is initially located at the bottom of the outer frame 1. The servo motor 5 is started, and the threaded shaft 15 rotates with the drive of the servo motor 5. Since the left side of the carrying plate 16 is meshed with the threaded shaft 15 and the right side is penetrated by the sliding rod 18, the carrying plate 16 moves upward to a position convenient for personnel to place under the forward rotation of the servo motor 5 (determined according to the best comfort of the staff), and then the non-woven fabric raw materials are stacked on the top of the carrying plate 16. When the top is stacked to a certain extent, the servo motor 5 is controlled to reverse. The rotation drives the carrying plate 16 to move slowly downward in the outer frame 1, so as to facilitate the subsequent placement of the staff, and when the carrying plate 16 moves in the outer frame 1, the balls 17 on both sides thereof will roll in the ball groove 9 on the inner wall of the outer frame 1, to ensure the stability of the movement of the carrying plate 16. After the placement is completed, the staff can push the push handle 6 to drive the whole to move along with the universal wheels 2 at the four corners of the bottom. The cross bar 7 on the inner side of the push handle 6 is used to increase the strength of the push handle to transport the non-woven material. After it reaches the appropriate position, the internal brake pad is stepped on to brake it, and then the non-woven material on the top is unloaded. Finally, the servo motor 5 rotates forward to drive the carrying plate 16 to move slowly upward, so as to facilitate the non-woven material at the bottom inside to be taken, thereby improving the convenience of loading and unloading materials.

[0036] Furthermore, the servo motor 5 used in the transporter is a Simotics S-1FK2 model, which has fast acceleration and deceleration capabilities, can achieve high-speed movement and rapid stopping in a short time, and uses reliable materials and processes, and has good durability and anti-interference capabilities.

[0037] like Figure 1-Figure 3 As shown, the bottom of the two groups of extension plates 8 are initially located inside the outer frame 1. According to the actual situation, when a large amount of materials are to be transported, the fixing parts 10 on the surface of the outer frame 1 are first taken out one by one, and then the handles 11 are pulled upward one by one to drive the extension plates 8 to move upward in the internal slide grooves 12 of the outer frame 1. The limiting plates 13 at the bottom of the extension plates 8 are used to limit them to prevent them from sliding out completely. After the surfaces of the extension plates 8 correspond to the connecting holes 14 on the surface of the outer frame 1 one by one, the fixing parts 10 are connected to the corresponding connecting holes 14 one by one to fix the extension plates 8, thereby increasing the internal placement space and reducing the number of transports.

[0038] Working principle: First, the initial state of the carrier plate 16 is at the bottom of the outer frame 1. The servo motor 5 is started, and the threaded shaft 15 rotates with the drive of the servo motor 5, so that the carrier plate 16 moves upward to a position convenient for personnel to place under the positive rotation of the servo motor 5. Then, the non-woven fabric raw materials are stacked on the carrier plate 16. When the upper part is stacked to a certain extent, the servo motor 5 is controlled to reverse and drive the carrier plate 16 to slowly move down in the outer frame 1, so as to facilitate the subsequent placement of the staff. After the placement is completed, the staff can push the push handle 6 to drive the whole body to move along the universal wheels 2 at the four corners of the bottom to transport the non-woven fabric materials. , after reaching the appropriate position, step on the internal brake pad to brake it, then unload the non-woven material on the top, and then the servo motor 5 rotates forward to drive the carrying plate 16 to slowly move upward, so as to facilitate the non-woven material below the inside to be taken, thereby improving the convenience of loading and unloading materials, and when there are a lot of non-woven materials to be transported, the staff can take out the fixing part 10 and pull the extension plate 8 upward. After it is limited by the limiting plate 13 to the appropriate position, the fixing part 10 is connected to the corresponding connecting hole 14 in turn to complete the fixing of the extension plate 8, thereby increasing the longitudinal area of ​​the outer frame 1, so that more non-woven materials can be placed at one time.

[0039] In this embodiment: the control circuit of the control panel 4 can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the art. It is only used without modification, so the control method and circuit connection are not described in detail.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
