Detailed implementation mode

[0025] The present invention provides a wallboard of a paper receiving machine frame, a paper receiving machine frame and a paper feeding unit frame structure. To make the purpose, technical solution and effect of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it cannot be understood as a limitation to the present invention. In addition, "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Therefore, the features defined with "first", "second", "third" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0027] In the production process of carton board, it is generally made by adhesively bonding multiple layers of base paper online, and the feeding of the base paper generally requires the use of a paper receiving machine and a base paper rack. The existing paper receiving machines and base paper racks are generally produced separately. Since the paper receiving machine frame has a relatively large size, especially a relatively wide lateral dimension, it is easily restricted by the loading space during transportation and needs to disassemble and load the paper receiving machine frame and the base paper rack, and then assemble them into a complete machine at the customer site. At present, this installation method requires additional on-site installation personnel. Although it saves the loading space, the installation cost is high, which greatly increases the cost of the enterprise. In order to improve the current situation of the industry, the present invention provides a wall of a paper receiving machine frame, which can switch between the working mode and the transportation mode. In the transportation mode, the width of the wall is shortened, the limitation of the loading space is reduced, and on-site professional personnel are not required for installation, which greatly saves the installation time cost and economic cost.

[0028] Please refer to Figure 1-7, the present invention provides a wall panel of a paper splicing machine frame. The wall panel 3 includes a first wall panel 4, a second wall panel 5 and a third wall panel 6. The first wall panel 4 and the third wall panel 6 are respectively detachably connected to both sides of the second wall panel 5, and the first wall panel 4 and the third wall panel 6 can respectively rotate downward by a certain angle with their connection points with the second wall panel 5 as the fulcrums. The first wall panel 4, the second wall panel 5 and the third wall panel 6 adopt a detachable connection structure, so that they can be converted into different forms during normal operation and transportation to reduce the loading space required for transportation.

[0029] The angles by which the first wall panel 4 and the third wall panel 6 rotate downward are not greater than 90 degrees, and the preferred angle is 90 degrees, which just makes the first wall panel 3 and the third wall panel 3 perpendicular to the horizontal plane, saving the most space in the transverse length. If the folding angle is less than 90 degrees, the transverse length of the wall panel cannot be minimized to the greatest extent; if the folding angle is greater than 90 degrees, the first wall panel and the third wall panel may interfere with the second wall panel, making it difficult to achieve.

[0030] In this embodiment, as Figure 1 , 3 and 4, when the wall panel 3 of the paper splicing machine frame is in normal operation, it is in a "T" shape, and the longitudinal length and transverse length dimensions are 2472×3850 mm; during transportation, after the first wall panel 4 and the third wall panel 6 are rotated downward by 90 degrees, the first wall panel 4 and the third wall panel 6 are in a folded state, so that the longitudinal length and transverse length dimensions of the wall panel 3 of the paper splicing machine frame are 2278×2316 mm, greatly shortening the transverse length and meeting the transportation space of a standard container.

[0031] In order to achieve detachable connection between the first wall panel 4 and the second wall panel 5, and between the second wall panel 5 and the third wall panel 6, mounting grooves 7 are respectively provided on the inner sides of the first wall panel 4 and the third wall panel 6, and mounting holes 8 corresponding to the mounting grooves 7 are respectively provided on both sides of the second wall panel 5; the "inner side" here refers to the side where the first wall panel 4 and the third wall panel 6 are respectively connected to the second wall panel 5; the wall panel 3 further includes fixing pins 9 and cover plates 10 corresponding to and connected to the mounting grooves 7 and the mounting holes 8. The fixing pins 9 include a positioning portion and a connecting portion. The positioning portion is located at one end, and the outer diameter of the positioning portion is greater than the inner diameters of the mounting hole 8 and the mounting groove 7. The outer diameter of the connecting portion is not greater than the inner diameters of the mounting hole 8 and the mounting groove 7. The connecting portions of the two fixing pins 9 respectively pass through the mounting groove 7 on the first wall panel 4 and the mounting hole 8 on one side of the second wall panel 5 or the mounting groove 7 on the third wall panel 6 and the mounting hole 8 on the other side of the second wall panel 5. The free end of the connecting portion is covered with the cover plate 10. Through the limiting action of the positioning portion and the cover plate 10, the first wall panel 4 and the third wall panel 6 are fixed on the second wall panel 5. In other embodiments, the fixing pins and the cover plates 10 can also be in the structure of bolts and nuts. One end of the bolt passes through the mounting hole 8 and the mounting groove 7, and then is locked with a nut to fix the first wall panel and the third wall panel on the second wall panel 5 respectively.

[0032] In order to further improve the connection stability between the first wall panel 4 and the second wall panel 5, and between the third wall panel 6 and the second wall panel 5, one or more first through holes 11 are further provided on the positioning portion of the fixing pins. The first wall panel 4, the second wall panel 5 and the third wall panel 6 are respectively provided with second through holes 12 corresponding to the first through holes 11. The first through holes 11 and the second through holes 12 are fixed by screws, which is easy to disassemble and assemble. When there are multiple first through holes 11, they are circumferentially distributed along the edge of the fixing pin 9 to ensure uniform force on the fixing pin 9; a plurality of second through holes 12 corresponding to the first through holes 11 are provided on the peripheries of the upper and lower parts of the mounting groove 7. The first wall panel 4 and the third wall panel 6 can still be fixed by this structure after being folded.

[0033] When the mounting groove 7 is a straight groove, when the first wall panel 4 and the third wall panel 6 rotate downward to a certain angle, their edges will interfere with the second wall panel 5 and cannot rotate to the optimal folding state of 90 degrees. In order to minimize the size of the paper receiving machine frame 1, in this embodiment, the mounting groove 7 is set as an arc groove. The opening of the arc groove faces outward and extends outward from top to bottom, increasing the distance between the lower part of the arc groove and the center line of the second wall panel 5. When the first wall panel 4 and the third wall panel 6 are folded downward, the fixing pin 9 is connected to the lower part of the arc groove, and the first wall panel and the third wall panel will not interfere with the second wall panel.

[0034] The present invention also provides a paper receiving machine frame 1, which includes two opposite wallboards 3. One or more cross beams are used to support and fix between the two wallboards 3. The paper receiving machine frame 1 further includes a plurality of guiding beams. The guiding beams are square tubes, and the corners on the length direction of the square tubes are smoothly transitioned, and the upper surface is inclined with respect to the horizontal plane, which plays a guiding role for the base paper, so that the paper outlet angle of the base paper meets the requirements of subsequent processes.

[0035] Please refer to Figure 4 , further, the present invention also provides a paper feeding unit frame structure, which includes the paper receiving machine frame 1 and a base paper rack 2. A positioning hole 13 is provided at the bottom of the second wallboard 5 in the paper receiving machine frame 1, and bumps 14 are respectively provided at both ends of the top of the base paper rack 2. When installing the paper feeding unit frame structure, by clamping the bumps 14 in the positioning holes 13, pre-positioning of the paper receiving machine frame 1 and the base paper rack 2 can be achieved, and then bolts are used to be screwed through the screw holes provided at the bottom of the second wallboard 5 and the screw holes at the top of the base paper rack 2 to fix the paper receiving machine frame 1 and the base paper rack 2. Preferably, a third through hole 15 extending in the horizontal direction is further provided on the bump 14, and a bolt with a length greater than the aperture of the positioning hole 13 can be connected in the third through hole 15 to prevent the paper receiving machine frame 1 from falling off during the installation process. Fixing holes for installing paper feeding rollers are provided on the base paper rack 2. The base paper roll is installed on the paper feeding rollers, and the motor drives the paper feeding rollers to rotate, driving the base paper to be conveyed downstream.

[0036] In this embodiment, when the paper feeding unit frame structure needs to be transported, the fixing pins 9 and the cover plates 10 are taken off. Rotate the first wallboard 4 on the left to a suitable position, and then install the fixing pin 9 into the installation slots 7 and the installation holes 8, and cover the cover plate 10; similarly, take off the fixing pins 9 and the cover plates 10 for fixing the second wallboard 5 and the third wallboard 6, rotate the third wallboard 6 on the right to a suitable position, and then install the fixing pin 9 into the installation slots 7 and the installation holes 8, and cover the cover plate 10. At this time, the first wallboard 4 and the third wallboard 6 of the paper feeding unit frame are folded towards the second wallboard 5, reducing the requirements for transportation space.

[0037] When the paper feeding unit frame arrives at the customer site, only the fixing pins 9 and the cover plates 10 need to be taken out respectively, and the reverse operation is performed according to the above steps to convert the paper feeding unit frame into a "T" - shaped structure in the working state, then it can work normally.

[0038] In summary, the present invention solves the drawback that the existing paper feeding unit frame structure of the paper receiving machine needs on - site assembly. The paper receiving machine frame and the base paper rack are integrated at the production end, making the structure of the equipment more compact, shortening the assembly time at the customer site, and greatly saving the assembly cost. The paper receiving machine frame can be converted in form according to different requirements, reducing the limitation of transportation space.

[0039] It will be understood that those of ordinary skill in the art can make equivalent substitutions or changes according to the technical solutions of the present invention and its inventive concept, and all such changes or substitutions should fall within the protection scope of the appended claims of the present invention.
