Technical Field

[0001] The invention relates to the technical field of umbrella production, in particular to a raw material slitting device for producing fiber umbrella ribs. Background Art

[0002] Umbrella ribs are one of the components of an umbrella. Fiber ribs are made of fiber lines and have the advantages of being light, flexible, and rust-resistant. When making fiber ribs from fiber lines, multiple strands of fiber lines are combined into one strand, and then the strand of fiber line is processed to become a fiber rod. Subsequently, the fiber rod is cut according to the actual length of the ribs to obtain fiber rods of different sizes. The ribs are then made by processes such as rubber coating. When cutting the fiber rods, a large number of fiber rods are usually cut at one time, which can easily cause the blade and the fiber rod to overheat, affecting the cutting quality.

[0019] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

The slide block 8 is provided with a transmission nut (not shown in the figure) that cooperates with the transmission screw 10, and the first rotating member 4 is hoisted on the slide block 8 through a connecting plate 11.

[0021] In order to prevent the temperature of the blade 5 from rising sharply and affecting the cutting effect, the cooling device includes: a protective cover 12 is provided on the first rotating member 4, and a temperature-changing block 13 that can expand and contract with temperature changes is provided on the protective cover 12. A sponge block 14 is provided on the temperature-changing block 13 for cooling the blade 5. The protective cover 12 is also provided with a plurality of water supply pipes 15 for supplying water to the sponge block 14; The temperature change block 13 is U-shaped to allow the fluid to spread naturally and fit the periphery of the blade 5; A water pump (not shown in the figure) is provided on the workbench 1 , the water outlet of the water pump is connected to the water supply pipe 15 , and the water inlet of the water pump is connected to a water source.

[0022] In order to make the temperature-changing block 13 more sensitive to temperature changes, a cavity 16 is provided in the temperature-changing block 13 , and the cavity 16 is filled with nitrogen. The temperature-changing block 13 is an elastic temperature-changing block 13 , and a guide device is also provided in the cavity 16 to prevent the temperature-changing block 13 from deflecting when expanding.

[0023] In order to prevent the temperature-changing block 13 from deviating from its direction when it expands due to heat, the guide device includes: a guide column 17 is provided on one side of the cavity 16, and a guide sleeve 18 is provided on the other side of the cavity 16 to match the guide column 17.

[0024] In order to prevent the temperature-changing block 13 from cracking due to multiple expansions and contractions, which would affect its service life, a plurality of deformation grooves 19 are further provided on the outer circumference of the temperature-changing block 13 .

[0025] In order to position the fiber rod and prevent it from shifting during cutting, the positioning device includes: a positioning plate 20 is provided at the front and rear ends of the mounting plate 3 between the L-shaped support plate 2, and a first telescopic member 21 is provided on the positioning plate 20, and the telescopic rod of the first telescopic member 21 passes through the positioning plate 20 and is connected to an anti-movement plate 22.

[0026] In order to prevent the fiber rod from being damaged during the pressing and positioning, and to enhance the positioning effect of the cylindrical object and reduce its shaking, the workbench 1 is further provided with a protective plate 23 for cooperating with the anti-movement plate 22. The protective plate 23 is a nylon plate and is provided with a plurality of positioning strips 24 corresponding to the axial direction of the fiber rod. The anti-movement plate 22 is provided with a buffer layer for preventing the fiber rod from being crushed. The buffer layer is a rubber layer. In order to facilitate the collection of the cut fiber rods, the workbench 1 is also provided with a collection device for collecting the cut fiber rods, and the collection device includes: a collection box 25 is provided on the side of the workbench 1, and a second telescopic member 26 is also provided on the workbench 1, and a push plate 27 is connected to the telescopic rod of the second telescopic member 26.

[0027] In order to reduce the burden of labor, avoid manual loading, and enable the fiber rod to be cut continuously, the workbench 1 is also provided with a feeding device for conveying the fiber rod, and the feeding device includes: a CNC feeder 28 is provided on the side of the workbench 1, and a support seat 29 is provided on the slide of the CNC feeder 28, and at least one third telescopic member 30 is provided on the support seat 29. The telescopic rod of the third telescopic member 30 passes through the support seat 29 and is connected to a pressing plate 31. The pressing plate 31 and the slide of the CNC feeder 28 are both provided with anti-slip buffer pads (not shown in the figure), and the anti-slip buffer pads (not shown in the figure) are rubber pads.

[0028] In order to prevent the fiber rods from being close to each other and resonating during cutting, which affects the cutting effect, the workbench 1 and the CNC feeder 28 are each provided with at least one separation plate 32 for keeping the fiber rods at an appropriate distance, and the separation plate 32 is provided with a plurality of through holes 33 for the fiber rods to pass through.

[0029] The first telescopic member, the second telescopic member and the third telescopic member are telescopic air cylinders, telescopic oil cylinders or telescopic electric cylinders.

[0030] Working principle: When in use, the user sequentially passes each fiber rod through the through-hole 33 on the separation plate 32, and then activates the third telescopic member 30 to control the pressing plate 31 to move downward, pressing the fiber rod against the slide of the CNC feeder 28. At this time, the CNC feeder 28 works, and the slide moves toward the workbench 1, so that the fiber rod is transported forward; Subsequently, the first telescopic member 21 is activated to control the anti-movement plate 22 to move toward the fiber rod, so that the fiber rod is pressed against the protective plate 23. Since most fiber rods are cylindrical, under normal conditions, the fiber rod has only two force points, the upper and lower points, after being positioned. However, a large number of positioning strips 24 parallel to the axial direction of the fiber rod are densely distributed on the protective plate 23. Therefore, the fiber rod can be positioned at three points, improving positioning stability and preventing deviation during cutting. At this time, the first rotating member 4, the second rotating member 9 and the water pump are started. The first rotating member 4 controls the blade 5 to rotate, and the second rotating member 9 controls the blade to move horizontally for cutting. Due to the material of the fiber rod, some powder debris will be produced during cutting. At this time, the water in the sponge will begin to drip due to the continuous water supply from the water pump, thereby playing a dust-proof role. After the cutting is completed, the first telescopic member 21 releases the positioning of the fiber rod. At this time, the second telescopic member 26 is activated, driving the push plate 27 to move, pushing all the cut fiber rods into the collection box 25. At this time, the third telescopic member 30 is activated to release the pressure on the fiber rod, and then moves away from the workbench 1, and then presses the fiber rod again, moving towards the workbench 1, and repeats the cycle. After a long period of cutting, due to the uninterrupted operation of the blade 5, the temperature of the blade 5 continues to rise under the action of friction. At this time, the temperature-changing block 13 and the nitrogen in the temperature-changing block 13 continue to expand under the action of high temperature, causing the sponge block 14 to approach the blade 5 until it abuts against the blade 5, allowing the cooling water to directly contact the blade 5 to cool it down, preventing it from overheating and rapid wear during cutting, which would affect its service life.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
