Description

Technical Field

[0001] The utility model relates to the technical field of glue spraying machines, in particular to a steel knife feeding, welding and glue spraying machine. Background Art

[0002] A steel knife, as the name suggests, is a type of cutting tool. During its production process, it is often necessary to weld the handle and the blade. After welding, in order to improve the aesthetics and oxidation resistance of the weld, a glue sprayer is required for glue protection. A glue sprayer is a device that specifically controls adhesives and other coatings and drips and applies them to the surface of the product.

[0003] However, the gluing head of the gluing nozzle in the existing gluing machine is a conical reducing pipe with fixed specifications. In later use, the specifications of the gluing nozzle cannot be flexibly adjusted according to the needs of use, which reduces the applicability of the device in the later stage to a certain extent. At the same time, when gluing of different specifications is required, finding the required suitable gluing head for replacement will also increase the operation steps of the device, which will affect the use experience of the device.

[0004] Therefore, it is necessary to provide a new steel knife feeding welding glue machine to solve the above-mentioned technical problems. Utility Model Content

[0013] Preferably, when the arc-shaped guide rod moves toward the nozzle, the arc-shaped connecting piece moves outward along with the arc-shaped guide rod in the radial direction of the connecting tube, so that the nozzle diameter increases.

[0014] Preferably, when the arc-shaped guide rod moves toward the glue barrel, the arc-shaped connecting piece moves inward along with the arc-shaped guide rod in the radial direction of the connecting barrel, so that the diameter of the glue nozzle is reduced.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0037] See also Figures 1 to 8 The embodiment of the utility model provides a steel knife loading welding glue spraying machine, which includes: a glue spraying cylinder 1, and a connecting cylinder 2 connected to the glue spraying cylinder 1; a glue nozzle adjustment mechanism is arranged on the connecting cylinder 2, and the glue nozzle adjustment mechanism includes a plurality of arc-shaped connecting pieces 22 movably arranged on the connecting cylinder 2, and a flexible connecting piece 24 is connected between each two adjacent arc-shaped connecting pieces 22, and a guide limit piece 23 on the arc-shaped connecting piece 22 is slidably connected to an arc-shaped guide rod 41, and the arc-shaped guide rod 41 is connected to a hand-held part 51, and the hand-held part 51 is threadedly connected to the connecting cylinder 2.

[0038] It should be noted that the nozzle adjustment mechanism drives the arc guide rod 41 to move on the connecting tube 2 through the hand-held part 51, so that the arc connecting piece 22 is bent and changed in cooperation with the arc guide rod 41 through the guide limit piece 23, so that the nozzle diameter formed by the arc connecting piece 22 and the flexible connecting piece 24 changes.

[0039] In the embodiments of the present invention, please refer to Figure 2 and Figures 4 to 8 The nozzle adjustment mechanism further includes a connecting ring 4 connected to the arc-shaped guide rod 41 , a driving ring 5 is provided on the hand-held portion 51 , and a limiting ring 52 connected to the connecting ring 4 is provided on the driving ring 5 .

[0040] It should be noted that: when the arc-shaped guide rod 41 moves toward the glue nozzle, the arc-shaped connecting piece 22 is displaced outwardly along with the arc-shaped guide rod 41 in the radial direction of the connecting tube 2, thereby increasing the diameter of the glue nozzle; when the arc-shaped guide rod 41 moves toward the glue tube 1, the arc-shaped connecting piece 22 is displaced inwardly along with the arc-shaped guide rod 41 in the radial direction of the connecting tube 2, thereby reducing the diameter of the glue nozzle.

[0041] In the embodiments of the present invention, please refer to Figure 2 and Figure 4 A connecting portion 21 is connected between the multiple arc-shaped connecting pieces 22 and the connecting tube 2. The multiple arc-shaped connecting pieces 22 are distributed in a circular array on the connecting portion 21. The guide limit piece 23 is arranged in the middle of the arc-shaped connecting piece 22. A guide hole 231 is opened on the guide limit piece 23. The arc-shaped guide rod 41 slides through the guide hole 231.

[0042] It should be noted that the cross section of the arc-shaped connecting piece 22 is a trapezoidal structure, the wide end of the arc-shaped connecting piece 22 is connected to the connecting portion 21, and the narrow end of the arc-shaped connecting piece 22 cooperates with the flexible connecting piece 24 to form a nozzle.

[0043] In the embodiments of the present invention, please refer to Figure 1 and Figure 3The hand-held portion 51 is detachably connected to the sealing cover 3, and the inner wall of the sealing cover 3 is provided with a sealing gasket 31 that contacts the nozzle.

[0044] It should be noted that the sealing cover 3 is set to seal the glue gun part in time after the gluing is completed, and the sealing gasket 31 is set to seal the glue nozzle to reduce the impact of its contact with external air, dust and impurities, and reduce the phenomenon of glue condensation for subsequent use.

[0045] The working principle of the steel knife feeding welding and gluing machine provided by the utility model is as follows:

[0046] By rotating the hand-held part 51, it can be moved on the connecting tube 2. Since the driving ring 5 and the connecting ring 4 are limited by sliding, and the guide limiting piece 23 also limits the arc-shaped guide rod 41, the driving ring 5 will not drive the connecting ring 4 to rotate, but only drive the connecting ring 4 and the arc-shaped guide rod 41 to move in the axial direction of the connecting tube 2.

[0047] When the arc-shaped guide rod 41 moves toward the nozzle in the axial direction of the connecting tube 2, the arc-shaped connecting piece 22 is guided by the guide limit piece 23 on the arc-shaped guide rod 41 and moves outward in the radial direction of the connecting tube 2, so that the diameter of the nozzle increases.

[0048] When the arc-shaped guide rod 41 moves toward the glue-spraying cylinder 1 in the axial direction of the connecting cylinder 2, the arc-shaped connecting piece 22 is guided by the guide limit piece 23 on the arc-shaped guide rod 41 and moves inward in the radial direction of the connecting cylinder 2, so that the diameter of the glue nozzle is reduced; thereby achieving the effect of adjusting the size of the glue nozzle and improving the application range of the glue-spraying machine; and the enlarged glue nozzle is also convenient for cleaning and handling after disassembly, which brings convenience to the operator.

[0049] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0050] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
