Description

Technical Field

[0001] This utility model relates to the technical field of screen drum processing equipment, and in particular to a screen drum support ring arrangement device. Background Technology

[0002] Pressure screen drums are widely used in papermaking pulp screening to screen shredded waste paper pulp, separating paper fibers from light and heavy impurities. The pressure screen drum is made by machining grooves on a reinforcing ring, inserting the machined bars one by one into the grooves of the support ring, and then connecting the bars to the support ring by welding or bonding.

[0003] Before inserting the bars, multiple support rings need to be coaxially arranged and fixed according to the design spacing using temporary brackets or mandrels to ensure that each ring is parallel and the spacing is consistent. Then, the single bar is passed through the positioning grooves or slots of all support rings in sequence, and the tooling is used to ensure that the slots of all support rings are aligned.

[0004] Currently, the support rings are arranged using temporary brackets or mandrels, which only allows multiple support rings to be arranged at the required spacing. It is difficult to accurately position the toothed grooves in each support ring, making it difficult for the bar to be accurately inserted into the toothed grooves of each support ring during insertion, thus affecting processing efficiency and accuracy. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a screen drum support ring arrangement device to solve the problem that it is difficult to position the support ring tooth groove and it is inconvenient to insert the bar in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a screen drum support ring arrangement device, including a base, a column vertically arranged on the base, a horizontal plate rotatably connected to the column about the axis of the column for placing the support ring, and a positioning piece rotatably connected to the horizontal plate and capable of being inserted into a toothed groove. The horizontal plate is arranged in multiple equidistant positions along the axial direction of the column, and the column is provided with a positioning post capable of abutting against and positioning the side wall of each horizontal plate.

[0007] By adopting the above technical solution, the support rings can be placed one by one on the horizontal plate of the support column. The positioning plates on the horizontal plate abut against the toothed grooves on each support ring, thereby positioning the position of the toothed grooves on the support rings on each horizontal plate. Then, by rotating the horizontal plate, the positioning post of each horizontal plate is abutted against, thereby positioning each horizontal plate and thus positioning the position of the support rings on each horizontal plate. This allows the toothed grooves on each support ring to be positioned vertically, which facilitates the insertion of the bars. Furthermore, the positioning plates adopt a rotating connection method, which will not cause interference when inserting the bars, making it easier for workers to use and improving the processing efficiency of the screen drum.

[0008] In one embodiment of the present invention, the two ends of the horizontal plate are respectively provided with support plates that can slide horizontally to abut against the lower side of the support ring. The support plates are provided with relief grooves that communicate with the tooth grooves of the support ring. The positioning piece is rotatably connected in the relief groove and can be flipped into the tooth groove.

[0009] By adopting the above technical solution, the support ring can be supported by the support plate that is slidably connected in the horizontal plate, and the positioning piece is set in the relief groove, which makes it easier for it to abut against the toothed groove on the positioning support ring, without interfering with the installation of the bar, and can be adapted to support rings with various inner diameters.

[0010] In one embodiment of the present invention, the positioning piece is L-shaped, with one end of the positioning piece facing upward and protruding out of the relief groove, and the other end of the positioning piece is provided with a connecting shaft that is rotatably connected to the support plate. The connecting shaft is provided with an elastic element that enables the positioning piece to reciprocate around the axis of the connecting shaft.

[0011] By adopting the above technical solution, the positioning piece can be rotated back and forth around the connecting shaft by the elastic element, making it easier for it to abut against the positioning support ring, and making the operation more convenient.

[0012] In one embodiment of the present invention, sliders that are slidably connected to the sidewalls of the support plate are also provided at both ends of the connecting shaft, and the two ends of the connecting shaft are respectively rotatably connected to the sliders on both sides.

[0013] By adopting the above technical solution, the positioning piece can be slid along the moving direction of the support plate via the slider, thereby adjusting the position of the positioning piece to make it more targeted.

[0014] In one embodiment of the present invention, a collar is provided at the center of the horizontal plate and is rotatably connected to the support column. Through grooves are provided at both ends of the horizontal plate in the horizontal direction, and the support plate is slidably connected in the through grooves.

[0015] By adopting the above technical solution, the horizontal plate can be rotatably connected to the center of the support column, and the axis of the support ring can be made to coincide with the axis of the support column when the support ring is placed.

[0016] In one embodiment of this utility model, the positioning column is arranged parallel to the column axis along the column side, the positioning column is fixedly connected to the column through the support plate, and the positioning column can abut against the side wall of the horizontal plate.

[0017] By adopting the above technical solution, the positioning posts can abut against each horizontal plate respectively, thereby achieving synchronous positioning of each horizontal plate.

[0018] In one embodiment of the present invention, each of the horizontal plates is provided with a magnetic suction element that can be magnetically connected to the positioning post, and the positioning post is provided with a metal part on its corresponding side wall.

[0019] By adopting the above technical solution, when the horizontal bar contacts the positioning column, it can be magnetically attracted and fixed, thus preventing the horizontal bar from shaking and affecting the positioning accuracy.

[0020] As described above, the screen drum support ring arrangement device of this utility model has the following beneficial effects: it can place the support rings one by one on the horizontal plate on the support column, and the positioning plates on the horizontal plate respectively abut against the toothed grooves on each support ring, thereby positioning the position of the toothed grooves on the support rings on each horizontal plate. Then, by rotating the horizontal plate, the positioning post abutting each horizontal plate is used to position each horizontal plate, thereby positioning the position of the support rings on each horizontal plate, so that the toothed grooves on each support ring can be positioned vertically, which facilitates the insertion of the bars. Moreover, the positioning plates adopt a rotating connection method, which can avoid interference when inserting the bars, making it convenient for workers to use and improving the processing efficiency of the screen drum.

[0028] like Figure 1 , Figure 2 As shown, this utility model provides a screen drum support ring arrangement device, including a base 1, a column 2 vertically arranged on the base 1, a horizontal plate 3 rotatably connected to the column 2 around the axis of the column 2 for placing the support ring 4, and a positioning piece 6 rotatably connected to the horizontal plate 3 and capable of being inserted into the tooth groove 5. Multiple horizontal plates 3 are arranged equidistantly along the axial direction of the column 2, and the column 2 is provided with a positioning post 7 that can abut against and position the side wall of each horizontal plate 3.

[0029] The support column 2 is located at the center of the base 1. A collar 8 is provided at the center of the crossbar that can be fitted onto the support column 2. The crossbar is rotatably connected to the support column 2 through the collar 8. Each crossbar is arranged equidistantly on the support column 2. A through groove 9 is provided at both ends of the crossbar. Support plates 10 are provided at both ends of the cross plate 3, which can slide horizontally and connect to the through groove 9 and abut against the lower side of the support ring 4. The two support plates 10 can slide along the through groove 9 respectively, thereby adjusting the support range and adapting to support rings 4 of different diameters.

[0030] The support plate 10 is provided with a relief groove 11 that communicates with the tooth groove 5 of the support ring 4. The positioning piece 6 is rotatably connected to the relief groove 11 around the horizontal plane and can be flipped from bottom to top into the tooth groove 5. The positioning piece 6 is L-shaped, with one end of the positioning piece 6 facing upward and protruding out of the relief groove 11. The other end of the positioning piece 6 is provided with a connecting shaft 12 that is rotatably connected to the support plate 10. The connecting shaft 12 is provided with an elastic element 13 that allows the positioning piece 6 to reciprocate around the axis of the connecting shaft 12.

Each side wall of the horizontal plate 3 is provided with a magnetic suction component that can be magnetically connected to the positioning column 7. The side wall of the positioning column 7 is correspondingly provided with a metal part 18.

[0034] In summary, this utility model allows the support rings 4 to be placed one by one on the horizontal plate 3 of the support column 2. The positioning pieces 6 on the horizontal plate 3 abut against the toothed grooves 5 on each support ring 4, thereby positioning the position of the toothed grooves 5 on each support ring 4 on the horizontal plate 3. Then, by rotating the horizontal plate 3, the positioning post 7 of each horizontal plate 3 is abutted against, thereby positioning each horizontal plate 3 and thus positioning the support ring on each horizontal plate 3. This allows the toothed grooves 5 on each support ring 4 to be positioned vertically, which facilitates the insertion of the bars. Furthermore, the positioning pieces 6 adopt a rotating connection method, which can prevent interference when inserting the bars, making it convenient for workers to use and improving the processing efficiency of the screen drum.
