Description

Technical Field

[0001] The present application relates to the field of test platforms, and in particular to a cutting test platform for a water needle roll changing device. Background Art

[0002] The water-jet paper cutting machine is an essential wet paper cutting device for any paper machine. Its dust-free cutting process, clean and neat cut edges, and high operational safety are key features. Before shipping, water-jet paper cutting machines typically undergo quality inspections to simulate actual operating conditions. Since only the water-jet paper cutting machine's cutting performance is tested, workers design a support platform to place cut samples. Currently, this support platform primarily consists of a bracket and a testing platform. The testing platform is secured to the bracket and has through-holes for clearance.

[0003] The current support platform has poor adjustment capabilities and cannot adapt to different types of paper guide needles, which affects the testing work of the paper guide needles. Utility Model Content

[0029] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The present application embodiment discloses a cutting test platform for a water needle roll changing device, such as Figure 1 As shown, the apparatus comprises a support frame 1 and a platform 2, with the platform 2 positioned above the support frame 1. A lifting frame 3 is provided below the platform 2. The lifting frame 3 and the support frame 1 slide relative to each other in the vertical direction, and a control assembly 4 is provided on the support frame 1 to control the sliding of the lifting frame 3. The platform 2 and the lifting frame 3 rotate relative to each other, and a positioning assembly 5 is provided on the lifting frame 3 to control the positioning of the platform 2.

[0032] like Figure 1 and 2 As shown, the control assembly 4 includes a control rod 41 and a control nut 42. The length of the control rod 41 is vertical and is threadedly connected to the support frame 1. One end of the control rod 41 passes through the support frame 1 and abuts the lifting frame 3. The control nut 42 is threadedly connected to the control rod 41. When the height of the platform 2 needs to be adjusted, the operator rotates the control rod 41. The end of the control rod 41 passes through the support frame 1 and applies force to the lifting frame 3, thereby raising or lowering the lifting frame 3. The operator then screws into the control nut 42, which reinforces the control rod 41 and thus raises or lowers the platform 2.

[0033] like Figure 2 As shown, a lifting hole 31 is opened on the lifting frame 3, and a lifting block 11 is fixedly connected to the support frame 1; when the lifting frame 3 moves, the movement of the lifting frame 3 can drive the movement of the lifting block 11, so that the lifting block 11 slides in the lifting hole 31. The lifting block 11 can limit the sliding of the lifting frame 3, thereby improving the stability of the lifting frame 3 when sliding.

[0034] like Figure 1 、 2As shown in Figure 3, a first connecting plate 21 is fixedly connected to the bottom of the platform 2, and a second connecting plate 32 is fixedly connected to the lifting frame 3. The first connecting plate 21 and the second connecting plate 32 are in contact with each other and are rotatably connected. The positioning assembly 5 includes a positioning bolt 51 and a positioning nut 52. The positioning bolt 51 passes through the first connecting plate 21 and the second connecting plate 32. The positioning nut 52 is threadedly connected to one end of the positioning bolt 51 that passes through the second connecting plate 32. When the angle of the platform 2 needs to be adjusted, the operator can rotate the platform 2. The rotation of the platform 2 can drive the rotation of the first connecting plate 21, and the second connecting plate 32 can provide support for the rotation of the first connecting plate 21. When the platform 2 is rotated to a suitable angle, the operator can pass the positioning bolts 51 through the first connecting plate 21 and the second connecting plate 32 in sequence, and then screw in the positioning nuts 52. The positioning nuts 52 are rotated until they abut against the second connecting plate 32. The positioning nuts 52 can limit the first connecting plate 21 and the second connecting plate 32, thereby fixing the first connecting plate 21 and the second connecting plate 32, thereby fixing the platform 2.

[0035] like Figure 1 As shown, the platform 2 is connected by bolts with two first support plates 22 and two second support plates 23. The first support plates 22 and the second support plates 23 are used to place cutting samples. The two first support plates 22 are in close contact with each other, and an avoidance hole 231 is formed between the two second support plates 23. The two first support plates 22 and the two second support plates 23 are used to place cutting samples, and the avoidance hole 231 can reduce the possibility of collision between the paper guide needle and the second support plate 23 during paper cutting.

[0036] like Figure 1 As shown, a pressing plate 24 is provided on the first support plate 22, and a connecting bolt 221 is threadedly connected to the first support plate 22. A connecting hole 241 is formed on the pressing plate 24, and the connecting bolt 221 slides in the connecting hole 241. When the pressing plate 24 needs to be installed, the operator can move the pressing plate 24 to a suitable position and then screw in the connecting bolt 221. The connecting bolt 221 can limit the position of the pressing plate 24, making it easier for the pressing plate 24 to move to apply force to the cutting sample, thereby reducing the possibility of the cutting sample being deflected during cutting.

[0037] The implementation principle of a cutting test platform for a water needle roll changing device in the embodiment of the present application is as follows:

[0038] To adjust the height of the sample being cut, the operator rotates the control lever 41, which raises the lifting frame 3, thereby raising the platform 2. The platform 2 then raises the sample being cut, facilitating adjustment to the desired height. To adjust the angle of the sample being cut, the operator rotates the platform 2, securing it with the positioning bolt 51 and positioning nut 52. This allows for adjustment of the sample's angle to accommodate different types of paper-feeding needles.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
