Description

Technical Field

[0001] This invention relates to the field of pipe cutting machine technology, and more specifically to a pipe cutting machine that facilitates material feeding. Background Technology

[0002] Yellow wax tubing (polyvinyl chloride fiberglass flexible tubing) is an electrical insulating tubing made of alkali-free fiberglass braided and coated with polyethylene resin through plasticization. This tubing has good flexibility, elasticity, insulation and chemical resistance. Yellow wax tubing is suitable for wiring insulation and mechanical protection of motors, electrical appliances, instruments, radio and other devices.

[0003] A computer-controlled pipe cutting machine is a fully automatic pipe cutting device. It refers to a device that uses a computer to control the cutting of waxed tubing. The length and quantity of the waxed tubing, as well as the feeding speed, can be freely set. It has pressure adjusting screws on both sides for automatic pressure and height adjustment, allowing for rapid material discharge. Computer-controlled pipe cutting machines offer high precision, low waste, simple operation, and high automation, greatly improving work efficiency. They are widely used in various industries, and with the rapid development of the electronics industry, their use is becoming increasingly common to meet market demands.

[0004] However, existing computerized pipe cutting machines still have shortcomings: First, when a pile of waxed tubes is placed on the ground and then inserted into the computerized pipe cutting machine, the waxed tubes are prone to tangling during continuous automated cutting, resulting in uneven force on each tube. This reduces the friction during feeding, causing slippage and inconsistent cut lengths. In addition, when the waxed tubes are driven onto the feeding rollers, they are prone to wobbling and shifting, which accumulates errors in the cut tubes, resulting in low cutting accuracy. All of these factors lead to reduced production efficiency, wasted time, and lower production quality. Summary of the Invention

[0005] In order to overcome the above-mentioned technical problems, the purpose of this invention is to provide a tube cutting machine that facilitates material feeding, so as to solve the problem in the prior art that the yellow wax tubes are prone to knotting, resulting in uneven force on each yellow wax tube, which causes a decrease in friction during the feeding of the yellow wax tubes and causes length deviation after cutting, thus affecting the cutting quality of the yellow wax tubes.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A pipe cutting machine for easy material feeding includes a pipe cutting machine body. A feeding bracket is fixedly connected to one side of the pipe cutting machine body. A fixed frame is provided on the inner wall of the feeding bracket. Two sets of rotating shafts are rotatably connected inside the fixed frame. One set of rotating shafts can move up and down. The outer walls of both sets of rotating shafts are fitted with cylindrical airbags with adjustable air pressure. A conveying roller is also rotatably connected to the inner wall of the feeding bracket. Multiple sets of V-shaped grooves are formed on the conveying roller.

[0008] As a further embodiment of the present invention: the fixed frame has sliding grooves on both sides, and a slider is slidably connected inside the sliding groove. The two ends of a set of rotating shafts are respectively rotatably connected to the two sets of sliders. An adjusting cylinder is fixedly connected to the top of the fixed frame. The output end of the adjusting cylinder passes through the fixed frame and is fixedly connected to a moving plate. Two sets of lifting rods are fixedly connected to the bottom of the moving plate. The bottoms of the two sets of lifting rods are respectively connected to the tops of the two sets of sliders.

[0009] As a further aspect of the present invention: both sets of rotating shafts are hollow inside, and the inside of the rotating shafts is connected to the airbag through a through hole. One end of each set of rotating shafts is fixedly connected to a rotary joint. An air supply pump is fixedly connected to the top of the fixing frame. The air supply pump is connected to the two sets of rotary joints through an air supply pipe.

[0010] As a further aspect of the present invention: a connecting plate is fixedly connected between the two sets of movable plates, and multiple sets of limiting rods are provided at the bottom of both sides of the connecting plate, with protective heads fixedly connected to the bottom of each set of limiting rods.

[0011] As a further aspect of the present invention: multiple sets of the limiting rods are slidably connected to the connecting plate, and springs are sleeved on the outer wall of the limiting rods, with the two ends of the springs abutting against the connecting plate and the limiting rods respectively.

[0012] As a further aspect of the present invention: there are two sets of conveying rollers, which are located on both sides of the fixed frame, and the V-grooves on the two sets of conveying rollers are in corresponding positions.

[0013] As a further embodiment of the present invention: a lifting cylinder is fixedly connected to the bottom of the fixed frame, the output end of the lifting cylinder passes through the fixed frame and is fixedly connected to a fixed plate, and two sets of rotating seats are fixedly connected to the top of the fixed plate, and the two sets of conveying rollers are respectively rotatably connected to the two sets of rotating seats.

[0014] As a further aspect of the present invention: two sets of sliding rods are fixedly connected to the bottom of the fixing plate, and the bottom of the two sets of sliding rods are slidably connected to the bottom of the fixing frame.

[0015] The beneficial effects of this invention are:

[0016] 1. In this invention, a set of rotating shafts drives the cylindrical airbags to move, and the distance between the two sets of cylindrical airbags is adjusted to facilitate the passage of wax tubes of different diameters. Then, the cylindrical airbags are inflated, and the expanded cylindrical airbags wrap around the outer wall of the wax tubes. Then, the friction generated between the rotating cylindrical airbags and multiple sets of wax tubes feeds multiple sets of wax tubes, avoiding uneven feeding lengths of the wax tubes and improving the consistency of subsequent cutting of multiple sets of wax tubes.

[0017] 2. In this invention, two sets of conveying rollers are set on both sides of the cylindrical airbag, and the V-shaped grooves on the two sets of conveying rollers are positioned correspondingly to convey the yellow wax tube. Then, the fireproof head at the bottom of the limiting rod limits the yellow wax tube in the V-shaped groove to prevent the yellow wax tube from being skewed and overlapping during conveying, which would cause the cutting to be tilted and improve the cutting quality of the yellow wax tube.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figures 1-5As shown, a pipe cutting machine for easy feeding includes a pipe cutting machine body 1 for cutting pipes. A feeding bracket 101 for feeding yellow wax pipes is fixedly connected to one side of the pipe cutting machine body 1. A fixed frame 2 is provided on the inner wall of the feeding bracket 101. Two sets of rotating shafts 3 are rotatably connected inside the fixed frame 2. One set of rotating shafts 3 can move up and down. The outer walls of both sets of rotating shafts 3 are fitted with cylindrical airbags 4 with adjustable air pressure. Two sets of conveying rollers 5 are also rotatably connected to the inner wall of the feeding bracket 101. Multiple sets of V-shaped grooves 501 are opened on the conveying rollers 5. The two sets of conveying rollers 5 are located on both sides of the fixed frame 2, and the positions of the V-shaped grooves 501 on the two sets of conveying rollers 5 are corresponding.

[0027] like Figure 2 and Figure 3 As shown, in order to facilitate the feeding adjustment of yellow wax tubes of different diameters, the fixed frame 2 is provided with sliding grooves 201 on both sides. Sliding blocks 6 are slidably connected inside the sliding grooves 201. The two ends of a set of rotating shafts 3 are respectively rotatably connected to the two sets of sliding blocks 6. An adjusting cylinder 601 is fixedly connected to the top of the fixed frame 2. The output end of the adjusting cylinder 601 passes through the fixed frame 2 and is fixedly connected to a moving plate 602. Two sets of lifting rods 603 are fixedly connected to the bottom of the moving plate 602. The bottom of the two sets of lifting rods 603 are respectively connected to the top of the two sets of sliding blocks 6. A drive motor 604 is provided on one side of a set of sliding blocks 6. The output end of the drive motor 604 is connected to a set of rotating shafts 3, thereby driving the cylindrical airbags 4 on the outer wall of the rotating shafts 3 to rotate and feed the yellow wax tubes.

[0028] like Figure 2 and Figure 3 As shown, in order to facilitate the inflation of the cylindrical airbag 4, both sets of rotating shafts 3 are hollow inside, and the interior of the rotating shafts 3 is connected to the cylindrical airbag 4 through the through hole 301. One end of each set of rotating shafts 3 is fixedly connected to a rotary joint 7. An air supply pump 701 is fixedly connected to the top of the fixing frame 2. The air supply pump 701 is connected to the two sets of rotary joints 7 through the air supply pipe 702, thereby supplying air to the interior of the rotating shafts 3. Then the air enters the interior of the cylindrical airbag 4 through the through hole 301, causing the cylindrical airbag 4 to expand and wrap around the yellow wax tube. Multiple sets of annular anti-slip rings are equidistantly arranged on the outer wall of each set of cylindrical airbags 4. When the cylindrical airbag 4 expands, the anti-slip rings are pressed and deformed against the surface of the yellow wax tube, thereby increasing the elastic friction of the anti-slip rings themselves.

[0029] like Figure 2As shown, in order to improve the stability of the yellow wax tube conveying, a connecting plate 8 is fixedly connected between the two sets of moving plates 602. Multiple sets of limiting rods 801 are provided on the bottom of both sides of the connecting plate 8. Protective heads 802 are fixedly connected to the bottom of each set of limiting rods 801. The protective heads 802 are made of rubber or foam. The multiple sets of limiting rods 801 are slidably connected to the connecting plate 8. Springs 803 are sleeved on the outer wall of the limiting rods 801. The two ends of the springs 803 abut against the connecting plate 8 and the limiting rods 801 respectively. When the adjusting cylinder 601 drives the moving plate 602 to move, the connecting plate 8 on the moving plate 602 drives the multiple sets of limiting rods 801 to move downward. The protective heads 802 at the bottom of the multiple sets of limiting rods 801 press and limit the yellow wax tube in the multiple sets of V-grooves 501. At the same time, the tension of the springs 803 adjusts the pressing force of the protective heads 802 on the yellow wax tube.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, in order to facilitate the adjustment of the height of the two sets of conveying rollers 5, so that the bottom of the yellow wax tube in the V-groove 501 is flush with the bottom set of cylindrical airbags 4, the bottom of the fixed frame 2 is fixedly connected to a lifting cylinder 9. The output end of the lifting cylinder 9 passes through the fixed frame 2 and is fixedly connected to a fixed plate 901. The top of the fixed plate 901 is fixedly connected to two sets of rotating seats 902. The two sets of conveying rollers 5 are rotatably connected to the two sets of rotating seats 902 respectively. The bottom of the fixed plate 901 is fixedly connected to two sets of sliding rods 903. The bottom of the two sets of sliding rods 903 is slidably connected to the bottom of the fixed frame 2. The lifting cylinder 9 drives the fixed plate 901 to move upward. The fixed plate 901 drives the two sets of conveying rollers 5 to move upward through the two sets of rotating seats 902, thereby completing the height adjustment of the conveying rollers 5.

[0031] The working principle of this invention is as follows: When using the device, the user places multiple sets of waxed tubes into the V-grooves 501 on the conveying roller 5, then passes one end of the waxed tube through the space between two sets of cylindrical airbags 4 and the V-grooves 501 on another set of conveying rollers 5, and then extends it into the tube cutting machine body 1. The user then starts the adjusting cylinder 601, which, through the moving plate 602 and the lifting rod 603, drives the cylindrical airbags 4 on a set of rotating shafts 3 to move downwards, so that the cylindrical airbags 4 are in contact with the upper surface of the waxed tubes. Then, the air supply pump 701 is started to supply air... Air pump 701 delivers air through air supply pipe 702 and rotary joint 7 into the cavity inside the two sets of rotating shafts 3, and then through through hole 301 into the two sets of cylindrical airbags 4. The two sets of cylindrical airbags 4 expand to wrap around the outer wall of the yellow wax tube, increasing the friction between the cylindrical airbags 4 and the yellow wax tube. Then, drive motor 604 is started, and drive motor 604 drives the cylindrical airbags 4 on one set of rotating shafts 3 to rotate. Through the friction between the cylindrical airbags 4 and the yellow wax tube, multiple sets of yellow wax tubes are moved to the tube cutting machine body 1 for tube cutting.

[0032] Simultaneously, when the adjusting cylinder 601 drives the moving plate 602 to move downward, the connecting plate 8 on the moving plate 602 drives multiple sets of limiting rods 801 on both sides to move downward. The multiple sets of limiting rods 801 move to the top of the yellow wax tube in the multiple sets of V-grooves 501 and abut against the upper side of the yellow wax tube, so as to avoid the yellow wax tube shaking when it is being transported and cut, and improve the stability of the yellow wax tube transport. In addition, the spring 803 sleeved on the outer wall of the limiting rod 801 can prevent the protective head 802 at the end of the limiting rod 801 from excessively pressing the yellow wax tube and causing deformation.

[0033] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
