Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and in particular to a feeding mechanism for a semi-automatic pipe cutting machine. Background Technology

[0002] A pipe cutting machine is a specialized piece of equipment that cuts pipes of various materials (such as steel, aluminum, and plastic) into sections of the required length and specifications using specific cutting methods (such as sawing or laser cutting). It typically consists of a cutting device, clamps, a transmission device, and a control system. It enables efficient and precise pipe cutting. Traditional manual feeding methods require significant manpower, resulting in low efficiency, cumbersome operation, and high labor intensity for workers. Direct contact between humans and machines increases the risk of workplace injuries. Therefore, a semi-automatic pipe cutting machine feeding mechanism is needed to reduce the frequency and intensity of manual operation and improve production efficiency.

[0003] Chinese Patent Publication No. CN205057632U discloses a feeding mechanism for a pipe cutting machine, relating to the field of pipe cutting production equipment. It includes a feeding frame, a slide table connected to the outlet of the feeding frame, a tilting plate for controlling feeding within the feeding frame, a sliding groove within the slide table whose edge connects to the outlet of the feeding frame, and a top block within the sliding groove. A long-stroke cylinder is installed at one end of the slide table, with its push rod connected to the top block. A blocking mechanism is installed at the other end of the slide table. This invention separates the feeding and cutting processes using a slide table. Workers only need to place the pipe material into the feeding frame for on-site electrical operation to achieve pipe cutting, thereby reducing the workload of workers and ensuring their safety.

[0004] However, the above-mentioned patent documents still have the following defects in practice;

[0005] Although the aforementioned patent document equipment can feed pipe cutting machines, manual insertion of pipes into the device is still required during use. The device cannot automatically complete part of the feeding process, resulting in untimely pipe supply. This may cause the pipe cutting machine to stop working while waiting for pipes, increasing manual operation time, reducing the overall feeding speed, and failing to guarantee the stability of the pipes during the feeding process through stable mechanical transmission and control methods. This may also cause the pipes to be subjected to unnecessary external interference. Utility Model Content

[0006] The main purpose of this utility model is to provide a semi-automatic pipe cutting machine feeding mechanism, which can effectively solve the problem of manual feeding.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 As shown, a semi-automatic pipe cutting machine feeding mechanism includes a chain conveyor 2. A frame 1 is fixedly connected to the right end of the chain conveyor 2. Several placement mechanisms 5 are fixedly connected in a rectangular distribution on the upper end of the chain conveyor 2. Several top-feeding mechanisms 4 are fixedly connected to the inner surface of the frame 1. A servo motor 7 is fixedly connected to the right side of the front end of one of the top-feeding mechanisms 4. Several hoppers 6 are fixedly connected to the right end of the frame 1. An electrical distribution box 8 is fixedly connected to the front end of the frame 1. An operating table 3 is fixedly connected to the front end of the electrical distribution box 8.

[0028] The aforementioned control panel 3 and power distribution box 8 can adopt the existing Omron PLC + Weintek touch screen CNC system, which uses teach-memory programming mode and can switch between automatic feeding mode and manual mode to suit different working conditions. The system has complete detection, fault self-diagnosis, interlock, alarm and protection functions. Other functions such as debugging, setting and manual are integrated into the touch screen, which is very intuitive. This utility model will not elaborate further.

[0029] In the specific implementation process of this utility model, several pipes are placed inside the bag hopper 6. Then, the operating table 3 and the power distribution box 8 control the start of the internal drive structure of the bag hopper 6 and the top material mechanism 4 to lift the pipes upward. Then, the top material mechanism 4 sends a single pipe onto the chain conveyor 2. Finally, the chain conveyor 2 and the placement mechanism 5 transport and cut the pipes.

[0030] Specifically, in order to achieve the purpose of feeding the pipe into the top material mechanism 4 for conveying, refer to Figure 2 In this solution, the conveyor belt hopper 6 includes a reducer 62 and a guard plate 61. The reducer 62 is fixedly connected to the lower right side of the support plate 41, and the guard plate 61 is fixedly connected to the right end of the support plate 41. A belt 63 is rotatably connected to the upper right side of the rear end of the support plate 41. Both the belt 63 and the guard plate 61 are C-shaped. An output shaft is rotatably connected to the front end of the reducer 62. The output end of the servo motor 7 is fixedly connected to the front end of the output shaft through a coupling.

[0031] In the above process, the servo motor 7 is started to drive the output shaft to rotate. Then, the output shaft winds the left side of the belt 63 behind the reducer 62. The belt 63 gradually straightens as it is being wound, thereby lifting the tube inside the guard plate 61. Since the right column of the guard plate 61 is higher than the left column, the belt 63 can smoothly lift the tube to the top of the top material mechanism 4.

[0032] Specifically, in order to achieve the purpose of pipe transportation, refer to Figure 2 In this scheme, the top material mechanism 4 includes several support plates 41, all of which are fixedly connected to the inner surface of the frame 1. The upper end of each support plate 41 is rotatably connected to a conveyor chain 43. A servo motor 42 is fixedly connected to the upper right side of the rear end of each support plate 41. A top material feeder 44 is fixedly connected to the upper left side of the rear end of each support plate 41. A feeding arm 46 is slidably connected to the upper front end of each support plate 41. A conveying mechanism 45 is fixedly connected to the middle front end of each support plate 41. The output end of the servo motor 42 is fixedly connected to the sprocket on the right side of the conveyor chain 43 via a coupling. A placement plate 461 is fixedly connected to the left end of the feeding arm 46. The placement plate 461 is Z-shaped.

[0033] In the above, by starting the servo motor 42, the conveyor chain 43 is driven to rotate, so that the pipe falling on the upper end of the conveyor chain 43 can be conveyed toward the chain conveyor 2.

[0034] The specific installation method, circuit connection method, and control method of the servo motor 42 used above are all conventional designs, which only need to drive the conveyor chain 43 to rotate. This utility model will not elaborate further.

[0035] Specifically, in order to achieve the goal of feeding the pipes into the upper part of the chain conveyor 2, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In this scheme, the conveying mechanism 45 includes two sprockets 451, which are rotatably connected to the middle of the front end of the support plate 41 and the left side of the middle of the front end, respectively. A chain 452 is wound around the outer surface of the two sprockets 451. A drive shaft 453 is fixedly connected to the middle of the sprocket 451 located in the middle. One end of the chain 452 is fixedly connected to the right side of the lower end of the feeding arm 46. The other end of the chain 452 is slidably connected and extends through the right wall of the feeding arm 46 to the outside. A motor is fixedly connected to the middle of the front end of the support plate 41. The output end of the motor is fixedly connected to the front end of the drive shaft 453 through a coupling.

[0036] Furthermore, the top feeder 44 includes a top plate 441 and a cylinder 442. The top plate 441 is slidably connected to the upper left side of the rear end of the support plate 41, and the cylinder 442 is fixedly connected to the upper left side of the rear end of the support plate 41. The output end of the cylinder 442 is fixedly connected to the lower right side of the top plate 441, and the upper end of the top plate 441 is inclined.

[0037] The specific installation method, air circuit connection method, and control method of the cylinder 442 used above are all conventional designs, which only need to be able to drive the top plate 441 to rise. This utility model will not elaborate further.

[0038] Furthermore, the placement mechanism 5 includes a base 51, which is fixedly connected to the upper end of the chain conveyor 2, and baffles 52 are fixedly connected to the left and right sides of the upper front part of the base 51.

[0039] In the above process, when the pipe is placed on the upper end of the placement plate 461, the second motor drives the second transmission shaft 453 to rotate, which in turn drives the first sprocket 451 to rotate. The first sprocket 451 then drives the chain 452 to rotate. Since a section of the chain 452 is fixedly connected to the lower end of the feeding arm 46, it drives the feeding arm 46 to be conveyed upwards on the chain conveyor 2 while rotating, thus feeding the pipe into the upper end of the base 51. Then, the top plate 441 lifts the pipe, and the inclined surface allows it to slide into the angle on the left side of the placement plate 461. The feeding arm 46 is then retracted. The inclined surface of the placement plate 461 prevents the pipe from sliding outwards through the stop bar 52.

[0040] It should be noted that the specific installation method, circuit connection method, and control method of the motor used in this utility model are all conventional designs, and will not be described in detail here.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
