DETAILED DESCRIPTION

[0021] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0022] Embodiment 1

[0023] like Figure 1-Figure 3 As shown, a mask nose strip conveying and positioning device proposed by the utility model includes a device body 1, a positioning plate 4 and a slider 6, on which a conveying groove 2 is opened, a friction conveying roller 3 driven by power is rotatably arranged in the conveying groove 2, the positioning plate 4 is horizontally arranged in the conveying groove 2 and is located on one side of the friction conveying roller 3, a slide groove 5 is opened inside, a slider 6 is slidably arranged in the slide groove 5, and the slider 6 has an adjustment limit mechanism cooperating with the positioning plate 4.

[0024] like Figure 2 As shown, there are multiple groups of sliders 6, and limiting channels 7 are formed between two adjacent groups of sliders 6, so that the nose strips can be limited from both sides during the transmission process by the sliders 6.

[0025] like Figure 3 As shown, the cross-sections of the slide groove 5 and the slider 6 are both set to a cross shape, and the four ends of the slide groove 5 respectively pass through the outside of the positioning plate 4. The cross-shaped structure is set to improve the fit between the slide groove 5 and the slider 6 and the stability of the slider 6 moving inside it.

[0026] Embodiment 2

[0027] like Figure 1-Figure 3 As shown, the utility model proposes a mask nose strip conveying and positioning device. On the basis of the above embodiment, this embodiment also records in detail the specific components of the adjustment and limiting mechanism, and the matching method between the adjustment and limiting mechanism and the positioning plate 4.

[0028] like Figure 3 As shown, the adjustment and limiting mechanism includes an elastic member, a slide plate 9, a connecting shaft 10, a strip plate 11 and an insertion rod 12. A groove 13 is provided on the top of the cross slider 6. The slide plate 9 is slidably arranged on the inner side of the groove 13 through the elastic member. A connecting shaft 10 passing through the positioning plate 4 is arranged on it. The strip plate 11 is arranged on the connecting shaft 10, and the insertion rod 12 is symmetrically arranged at the bottom of the strip plate 11.

[0029] like Figure 3 As shown, the elastic member includes a tension spring 14, the bottom end of the tension spring 14 is connected to the bottom of the groove 13, and the top end of the tension spring 14 is connected to the bottom of the slide plate 9, so that the tension spring 14 generates a downward elastic pulling force on the slide plate 9.

[0030] like Figure 2 and Figure 3 As shown, multiple groups of insertion holes 8 are linearly and equidistantly arranged on both sides of the top of the positioning plate 4, and the insertion rods 12 are inserted and connected with the corresponding insertion holes 8.

[0031] In summary, when the utility model is in use, the power part inside the device body 1 for driving the friction conveying roller 3 to rotate is the prior art, so it is not shown in the figure. In actual use, by driving the friction conveying roller 3 to rotate, the nose strip is driven to be synchronously conveyed under the action of friction force. During the conveying process, it passes through the limiting channel 7 and is limited on both sides by two sets of sliders 6. At the same time, when it is necessary to adjust the size of its limiting channel 7, an upward force is manually applied to the strip plate 11. Under the force, on the one hand, the strip plate 11 drives the slide plate 9 to stretch the tension spring 14 through the connecting shaft 10, so that Elastic deformation occurs and elastic potential energy is accumulated. On the other hand, the insertion rod 12 at the bottom of the strip plate 11 will disengage from the originally corresponding socket 8 as its own position rises, thereby driving it to release the limit, and then applying a lateral force to the strip plate 11, so that it drives the slider 6 to move in the slide groove 5. After moving to the desired location, the upward force applied to the strip plate 11 is released. At this time, the tension spring 14 releases elastic potential energy without external force to drive the slider 6 and the strip plate 11 to reset, thereby making the insertion rod 12 at the bottom of the strip plate 11 plug into the corresponding socket 8. The overall adjustment method is simple and has strong operability.

[0032] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
