Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipe packaging, in particular to a feeding device for a corrugated pipe surface protection film winding machine. Background Art

[0002] Metal bellows is a kind of wave-like pipe with regular shape. Commonly used metal bellows are carbon steel and stainless steel, steel lined with plastic, aluminum, etc. It is mainly used for non-concentric axial transmission with a small bending radius, or irregular turning, expansion, or absorbing thermal deformation of pipes, or for connecting pipes to pipes or pipes to equipment in occasions where it is not convenient to install with fixed elbows.

[0003] In the production of metal corrugated pipes, a protective film needs to be wrapped around the surface of the corrugated pipe before leaving the factory to effectively protect the surface of the corrugated pipe and reduce the contact between stains and corrosive liquids. This requires the use of a protective film wrapping machine for the wrapping work. Since the protective film of the protective film wrapping machine is made of PE or PVC, the rolled protective film is heavy. During the feeding process, the rolled protective film needs to be put on the feed shaft. This requires the feeding equipment to be lifted to the rated height and ensure that the center of the protective film roll is concentric with the feed shaft. The existing feeding equipment is difficult to adjust and it is difficult to quickly put the rolled protective film on the surface of the feed shaft. Utility Model Content

[0004] The utility model aims at the defects in the prior art and provides a feeding device for a corrugated pipe surface protective film winding machine.

[0005] The utility model is realized through the following technical solutions:

The lifting plate is arranged on the top of the scissor lift, and a supporting ball is clamped on the top of the lifting plate. The supporting assembly is movably arranged on the top of the lifting plate. The supporting assembly includes a rotating disk, an inclined plate, a clamping shaft, a push plate and an operating handle. The inclined plate is movably connected to the top of both sides of the rotating disk through a hinge, the clamping shaft is fixedly arranged at the bottom of the rotating disk, the push plate is clamped in the middle of the rotating disk, and the operating handle is clamped at one end of the push plate.

[0007] In a preferred embodiment of the utility model, the top end of the supporting ball contacts the bottom of the rotating disk;

[0009] In a preferred embodiment of the utility model, a limiting groove is provided on the top of the push plate, and the vertical section of the limiting groove is an isosceles trapezoidal structure;

[0010] The limiting groove is mainly used to effectively limit the rolled protective film to avoid lateral displacement during transportation.

[0012] The guide strips on both sides of the push plate effectively guide the sliding of the push plate in the slot at the top of the rotating disk.

[0013] In a preferred embodiment of the present utility model, one end of the clamping shaft penetrates through and extends to the inner side of the bottom of the lifting plate, and the clamping shaft is movably connected to the lifting plate.

[0014] The beneficial effects of the utility model are:

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0023] like Figure 1-5 The feeding equipment for a corrugated pipe surface protective film winding machine shown in the figure includes a scissor lift 1, a lifting plate 2 and a supporting assembly 3. The lifting plate 2 is arranged on the top of the scissor lift 1, and a supporting ball 4 is clamped on the top of the lifting plate 2. The supporting assembly 3 is movably arranged on the top of the lifting plate 2. The supporting assembly 3 includes a rotating disk 31, an inclined plate 32, a clamping shaft 33, a push plate 34 and an operating handle 36. The inclined plate 32 is movably connected to the top of both sides of the rotating disk 31 through a hinge, the clamping shaft 33 is fixedly arranged at the bottom of the rotating disk 31, the push plate 34 is clamped in the middle of the rotating disk 31, and the operating handle 36 is clamped at one end of the push plate 34.

[0024] Specifically, the top of the supporting ball 4 contacts with the bottom of the rotating disk 31, and a limiting groove 35 is provided on the top of the push plate 34. The vertical section of the limiting groove 35 is an isosceles trapezoidal structure. Guide strips are provided on both sides of the push plate 34. A clamping groove cooperating with the push plate 34 is provided on the top of the rotating disk 31. The inner wall of the clamping groove at the top of the rotating disk 31 is provided with guide grooves cooperating with the guide strips on both sides of the push plate 34. One end of the clamping shaft 33 passes through and extends to the bottom inner side of the lifting plate 2, and the clamping shaft 33 is movably connected to the lifting plate 2.

[0025] In this embodiment, the lifting plate 2 is first adjusted to the lowest position through the scissor lift 1, and then the inclined plate 32 is flipped to form inclined surfaces on both sides of the rotating disk 31, which is convenient for rolling the rolled protective film to the top of the supporting assembly 3, and a push plate 34 is provided on the top of the rotating disk 31. A limiting groove 35 with a trapezoidal vertical cross-section is provided in the middle of the push plate 34. In this way, the protective film roll will be stuck in the limiting groove 35 after rolling to the upper surface of the push plate 34, which will have a certain limiting effect during transportation.

[0026] Furthermore, the scissor lift 1 is moved to the position of the feed shaft of the protective film winding machine, and then the lifting plate 2 is raised by the scissor lift 1 to the same height as the center of the protective film roll and the center of the feed shaft. The operating handle 36 is clamped in the push plate 34, and its bottom is clamped in the clamping hole on the surface of the rotating disk 31. The rotating disk 31 can be rotated by holding the operating handle 36 so that the center of the protective film roll and the feed shaft are concentrically arranged. During the rotation, the supporting ball 4 provides effective support to the rotating disk 31. The operating handle 36 is lifted to separate its bottom from the clamping hole on the surface of the rotating disk 31, and then the push plate 34 is pushed forward to move it forward, so that the protective film roll can be directly sleeved on the outside of the feed shaft. The operation is simple and efficient.

[0027] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
