Description

Technical Field

[0001] The utility model relates to transportation equipment, in particular to a printing cardboard tractor. Background Art

[0002] In printing, some large cardboards have a large surface area after the traditional printing process, so they need to be left alone for a period of time to wait for the ink to dry before they can be transported; on the other hand, the static electricity after printing will also damage the printing quality of the product. Therefore, it is necessary to waste time waiting for a period of time before transportation. This greatly affects the overall transportation efficiency and the use area of ​​the factory. The cost and technical difficulty required to shorten the time are greater, so this problem has become a difficult problem in the industry. On the other hand, these cardboards will be displaced during transportation due to sudden braking or uneven ground factors, which will eventually affect the quality of the finished product, and the fixed structure itself may affect the product due to its own material hardness.

[0024] like Figure 1 As shown, a printed cardboard tractor comprises: a frame 100, a buffer structure 200, a wheel structure 300, a pull handle 400 and a wheel block structure 500, wherein the frame 100 is connected to the bottom end of the buffer structure 200, the wheel structure 300 is arranged on both sides of the frame 100, the pull handle 400 is connected to the front end of the frame 100, and the wheel block structure 500 is arranged at the side end of the frame 100;

[0025] Among them, the buffer structure 200 includes: a buffer bracket 210, a synchronous shaft 220, a pulley 230 and a belt 240. The buffer bracket 210 is arranged at the four corners of the frame 100, the pulley 230 is arranged at the upper and lower ends of the buffer bracket 210, the belt 240 is connected to the pulley 230, and the pulleys 230 are connected to each other through the synchronous shaft 220.

[0026] The vehicle frame 100 includes: a bottom frame 110 , a baffle 120 and a side plate 130 . The baffle 120 and the side plate 130 are disposed on both sides of the bottom frame 110 . The top end of the side plate 130 is connected to the synchronization shaft 220 .

[0027] The wheel structure 300 includes a fixed wheel 310 and a universal wheel 320 . The fixed wheel 310 is arranged at the rear end of the frame 100 , and the universal wheel 320 is arranged at the front end of the frame 100 .

[0028] like Figure 3 and 4 As shown, the wheel stop structure 500 includes: a fixing groove 510 and a stop baffle 520 . The fixing groove 510 is arranged on the side of the frame 100 . The stop baffle 520 is a U-shaped structure. The stop baffle 520 is plug-in connected to the fixing groove 510 .

[0029] The basic structure of the utility model is a tractor trailer. The printed paper is placed on it. Generally speaking, this tractor trailer is mainly suitable for large cardboard. In the actual production process, as mentioned in the background technology, whether it is drying or static electricity considerations, it needs a certain amount of time to stand still before it can be stacked and transported. Another problem is the lack of buffer fixation during transportation, and direct hard fixation can easily cause damage to the cardboard.

[0030] like Figure 2As shown, the principle of the utility model is to solve the above problems by adding a buffer structure 200. To summarize the above problems, it can be basically considered that there are the following directions. The first is the contradiction between buffering and support. Rigid fixation can easily cause damage to the cardboard. Therefore, a soft fixation method is needed. The utility model adopts a belt 240 as a fixing method, and a combination of pulleys 230 and belts 240 are arranged around to provide support forces on the left and right sides of the upper and lower sides of the quadrilateral cardboard respectively. The material of this support force is a soft, elastic and tough belt structure. Its support force is converted into friction force through the sliding force of the pulley 230. The second is the contradiction between spacing and fixation. Our expected idea is to replace the traditional static during transportation, so it is necessary to design an air barrier between these cardboards, and the air barrier layers must meet the soft fixation conditions of the previous one. As for the combination of belts and pulleys, as mentioned above, its soft surface will not damage the cardboard, and it can naturally form a vacuum layer between the cardboards without the need for other accessories. Because the belt is an elastic material, in actual use, we put the first piece of cardboard into the last layer, and the pulley can drive the belt to rotate, so the friction is not large. Since there is only one, this process is very easy. Then when the second piece of cardboard is printed, we continue to stack it. At this time, we can also reserve a large distance between the second and first pieces of cardboard. By analogy, as the number increases, the belt becomes more and more tensioned, and the distance between the cardboards becomes smaller and smaller. However, although the actual space interval that can be placed becomes smaller, the fixing force of the belt is also greater, so it will not fit completely. In summary, through the buffer structure designed by the utility model, it is possible to reserve space between cardboards and complete the fixation in a flexible manner.

[0031] The present invention has also made some improvements in other details. First, due to the addition of the buffer structure, a baffle 120 is added to the frame to increase the shielding support force at the bottom, and a side plate 130 is added to fix the buffer bracket 210 and the synchronous shaft 220. The synchronous shaft 220 is the rotation axis of the pulley 230, which facilitates the synchronous sliding of the left-right symmetrical buffer structure.

[0032] The wheel structure 300 is a combination of a conventional fixed wheel 310 and a universal wheel 320. Through the wheel block structure 500 placed at the side end, when the vehicle is stagnant, the stagnant baffle 520 can be taken out from the fixing groove 510 and then inserted into the front end of the wheel structure 300 to play a blocking role, so that the vehicle body will not move during the transportation process.

[0033] Compared with the traditional technology, the utility model has a buffer structure, which can fix the large cardboard on the one hand; on the other hand, the fixing structure is soft and can not damage the cardboard; finally, it naturally has a certain upper and lower buffer space, which can ensure that the drying time of the surface printing effect can be achieved during transportation.

[0034] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
