Technical Field

[0001] This invention relates to the field of umbrella manufacturing technology, and in particular to a raw material cutting device for producing fiber umbrella ribs. Background Technology

[0002] Umbrella ribs are one of the components of an umbrella. Fiber umbrella ribs are made from fiber threads and have advantages such as being lightweight, flexible, and rust-free. To make fiber umbrella ribs, multiple strands of fiber threads are combined into one, and then this strand is processed into a fiber rod. Subsequently, the fiber rod is cut according to the actual length of the umbrella rib to obtain fiber rods of different sizes. After processes such as coating, the umbrella ribs are made. When cutting the fiber rods, a large bunch of fiber rods is usually cut at once, which can easily cause the blades and fiber rods to overheat, affecting the cutting quality. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention proposes a raw material cutting device for the production of fiber umbrella ribs.

[0004] To achieve the above objectives, the technical solution of the present invention is to provide a raw material slitting device for fiber umbrella rib production, including a worktable, a cutting device on the worktable, and a positioning device to prevent the fiber rod from moving during cutting.

[0007] A further improvement is that the guiding device includes a guide post on one side of the cavity and a guide sleeve that cooperates with the guide post on the other side of the cavity.

[0008] A further improvement is that several deformation grooves are also provided on the outer periphery of the temperature-changing block.

[0009] A further improvement is that the positioning device includes a positioning plate located at both the front and rear ends of the mounting plate between the L-shaped support plates, and a first telescopic member is provided on the positioning plate. The telescopic rod of the first telescopic member passes through the positioning plate and is connected to an anti-movement plate.

[0010] A further improvement is that the workbench is also equipped with a protective plate for use with the anti-movement plate.

[0011] A further improvement is that the protective plate is provided with several positioning strips corresponding to the axial direction of the fiber rod, and the anti-movement plate is provided with a buffer layer to prevent damage to the fiber rod.

[0012] A further improvement is that the workbench is also equipped with a collection device for collecting the cut fiber rods.

[0013] A further improvement is that the collection device includes: a collection box is provided around the workbench, and a second telescopic component is also provided on the workbench, with a push plate connected to the telescopic rod of the second telescopic component.

Detailed Implementation

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] like Figures 1-8 As shown, a raw material cutting device for fiber umbrella frame production includes a workbench 1, a cutting device on the workbench 1, and a positioning device to prevent the fiber rod from moving during cutting. The cutting device includes: two L-shaped support plates 2 on the workbench 1, at least one mounting plate 3 between the L-shaped support plates 2, a first rotating component 4 on the mounting plate 3 via a driving device, a blade 5 on the rotating rod of the first rotating component 4, a clearance groove 6 on the workbench 1 matching the blade 5, and a cooling device between the first rotating component 4 and the blade 5.

[0030] The mounting plate 3 consists of two pieces;

[0031] To smoothly drive the first rotating component 4 to translate, the driving device includes: a slide rail 7 on each of the mounting plates 3, a slide block 8 on the slide rail 7, a second rotating component 9 on the L-shaped support plate 2, a transmission screw 10 rotatably mounted on the L-shaped support plate 2, the transmission screw 10 being connected to the rotating rod of the second rotating component 9, a transmission nut (not shown in the figure) on the slide block 8 cooperating with the transmission screw 10, and the first rotating component 4 being suspended on the slide block 8 via a connecting plate 11.

[0032] To prevent the blade 5 from overheating and affecting the cutting effect, the cooling device includes: a protective cover 12 on the first rotating part 4, a temperature-changing block 13 on the protective cover 12 that can expand and contract with temperature changes, a sponge block 14 on the temperature-changing block 13 for cooling the blade 5, and several water supply pipes 15 on the protective cover 12 for supplying water to the sponge block 14.

[0033] The temperature-changing block 13 is U-shaped to allow the fluid to spread naturally and conform to the outer periphery of the blade 5;

[0034] The workbench 1 is equipped with a water pump (not shown in the figure). The outlet of the water pump is connected to the water supply pipe 15, and the inlet of the water pump is connected to the water source.

[0035] In order to make the temperature-changing block 13 more sensitive to temperature changes, a cavity 16 is provided inside the temperature-changing block 13, and the cavity 16 is filled with nitrogen gas. The temperature-changing block 13 is an elastic temperature-changing block 13, and a guide device is also provided inside the cavity 16 to prevent the temperature-changing block 13 from shifting when it expands.

[0036] To prevent the temperature-changing block 13 from shifting direction when it expands due to heat, the guiding device includes: a guide post 17 on one side of the cavity 16, and a guide sleeve 18 that cooperates with the guide post 17 on the other side of the cavity 16.

[0037] To prevent the temperature-sensitive block 13 from cracking due to repeated expansion and contraction, thus affecting its service life, several deformation grooves 19 are also provided on the outer periphery of the temperature-sensitive block 13.

[0038] To position the fiber rod and prevent it from shifting during cutting, the positioning device includes: a positioning plate 20 is provided at both the front and rear ends of the mounting plate 3 between the L-shaped support plates 2, and a first telescopic member 21 is provided on the positioning plate 20. The telescopic rod of the first telescopic member 21 passes through the positioning plate 20 and is connected to an anti-movement plate 22.

[0039] To prevent the fiber rod from being damaged during clamping and positioning, and to enhance the positioning effect on cylindrical objects and reduce their wobbling, the workbench 1 is also provided with a protective plate 23 for cooperating with the anti-movement plate 22. The protective plate 23 is a nylon plate and has several 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.

[0040] To facilitate the collection of the cut fiber rods, the workbench 1 is also equipped with a collection device for collecting the cut fiber rods. The collection device includes: a collection box 25 arranged around the workbench 1, and a second telescopic member 26 on the workbench 1. A push plate 27 is connected to the telescopic rod of the second telescopic member 26.

[0041] To reduce the workload of manual labor and avoid manual feeding, allowing the fiber rods to be continuously cut, the workbench 1 is also equipped with a feeding device for conveying the fiber rods. The feeding device includes: a CNC feeder 28 is provided around the workbench 1, a support seat 29 is provided on the slide plate of the CNC feeder 28, 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 pressure plate 31, and both the pressure plate 31 and the slide plate of the CNC feeder 28 are 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.

[0042] To prevent the fiber rods from touching each other and resonating during cutting, thus affecting the cutting effect, both the workbench 1 and the CNC feeder 28 are equipped with at least one separation plate 32 to keep the fiber rods at an appropriate distance. The separation plate 32 has several through holes 33 for the fiber rods to pass through.

[0043] The first telescopic component, the second telescopic component, and the third telescopic component are telescopic cylinders, telescopic hydraulic cylinders, or telescopic electric cylinders.

[0044] Working principle: When in use, the user passes each fiber rod through the through hole 33 on the separation plate 32 in sequence, and then the third telescopic component 30 is activated to control the pressure plate 31 to move downward and press the fiber rods against the slide plate of the CNC feeder 28. At this time, the CNC feeder 28 is working and the slide plate moves towards the worktable 1, so that the fiber rods are conveyed forward.

[0045] Subsequently, the first telescopic component 21 is activated, controlling the anti-movement plate 22 to move towards the fiber rod, thereby pressing the fiber rod onto the protective plate 23. Since most fiber rods are cylindrical, under normal conditions, the fiber rod only has two force points after being positioned. However, the protective plate 23 has a large number of positioning strips 24 that are parallel to the axial direction of the fiber rod. Therefore, the fiber rod can be positioned at three points, improving positioning stability and preventing displacement during cutting.

[0046] At this time, the first rotating part 4, the second rotating part 9 and the water pump are started. The first rotating part 4 controls the blade 5 to rotate, and the second rotating part 9 controls the blade to move horizontally to cut. Due to the material of the fiber rod, some powder and debris will be produced during cutting. At this time, the water in the sponge will start to drip due to the continuous water supply from the water pump, thus playing a role in dust prevention.

[0047] After cutting is completed, the first telescopic component 21 releases the positioning of the fiber rod. At this time, the second telescopic component 26 is activated, driving the push plate 27 to move and push all the cut fiber rods into the collection box 25. At this time, the third telescopic component 30 is activated, releasing the pressure on the fiber rod, and then moves away from the worktable 1 and presses the fiber rod again. It then moves towards the worktable 1, and repeats the cycle.

[0048] After a long period of cutting, due to the continuous 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 gas inside the temperature-changing block 13 continue to expand under the action of high temperature, causing the sponge block 14 to move closer to the blade 5 until it comes into contact with the blade 5, so that the cooling water directly contacts the blade 5 to cool it down, preventing it from overheating and wearing out quickly during cutting, thus affecting its service life.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions above are merely illustrative of the principles of the present invention.

All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
