Description

Technical Field

[0001] The utility model relates to the technical field of tube breaking machines, in particular to a full-automatic tube breaking machine. Background Art

[0002] With the continuous development of society and the continuous advancement of science and technology, the technology related to the drum breaking machine is also constantly improving. The production of screen products is that the stainless steel wire is rolled and then woven into a screen drum by a resistance welding machine. The screen drum is then broken, that is, cut and separated. The unfolded screen sheet is leveled using a flat mesh machine, and finally cut according to the size requirements of the drawing.

[0003] There are two types of existing domestic stainless steel screen drum cutting processes. One is manual drum breaking. The rolled cylindrical screen drum is fixed on the angle iron frame. The operator uses a plasma cutting gun to cut it horizontally from one end face. When cutting to the other end face, one or two stainless steel wires are reserved without cutting. Then a wooden stick or a long iron rod is used to knock it open. This process has a high risk factor. The other is semi-automatic drum breaking. According to the diameter of the screen drum, a suitable diameter is selected to make a cylindrical semi-enclosed flat iron frame. The two ends of the frame are fixed with wire ropes and locking rings. Two electric hoists are installed to release the wire ropes to slowly unfold the broken stainless steel screen drum. The safety of the unfolding process is greatly improved. The screen drum is still cut by personnel operating the plasma cutting machine. Although this process avoids the problem of sudden unfolding of the screen drum and injuring people, the preliminary preparation work is complicated. The screen drum needs to be placed in the frame and the wire rope is retracted to fix it. In case of a stainless steel screen drum with a large diameter and a long length, two people are required to complete the operation, which will inevitably lead to reduced production efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: manual barrel breaking, which has a high process risk factor; semi-automatic barrel breaking, which has complex preliminary preparation work and low production efficiency, and to propose a fully automatic barrel breaking machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A fully automatic drum crusher comprises a main frame and a screening barrel, wherein a lower baffle is mounted on the main frame, a support column and a cutting beam are fixedly mounted on the main frame, an upper baffle is rotatably mounted on the main frame, and the upper baffle is connected to the support column via two hydraulic cylinders;

[0007] Two rotating assemblies are provided on the main frame, each of the rotating assemblies includes a wire tensioner rotatably mounted on the main frame, each of the wire tensioners is provided with a wire rope, locking assemblies are provided on both sides of the main frame, a cutting slide is slidably provided on the cutting beam, and a plasma straight-handled cutting gun is provided on the cutting slide.

[0008] Preferably, a cylinder is fixedly mounted on the cutting beam, and a driving end of the cylinder is fixedly connected to the cutting slide.

[0009] Preferably, two limit bars are fixedly connected to the cutting beam, and the cutting slide is slidably connected to the two limit bars.

[0010] Preferably, each of the locking assemblies includes a fixing cylinder fixedly mounted on a side surface of the main frame, the fixing cylinder is connected to the steel wire rope via a locking bolt, and a through opening for connecting the steel wire rope is provided on the fixing cylinder.

[0011] Preferably, two side surfaces of the main frame are rotatably connected to two guide wheels, and each of the steel wire ropes is in contact with the corresponding surface of the guide wheel.

[0012] Preferably, two servo motors are fixedly mounted on the main frame, and a driving end of each servo motor is fixedly connected to the corresponding wire tensioner.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The upper baffle and the lower baffle are combined with the steel wire to fully surround the screen barrel. After cutting, the screen barrel will not bounce off directly to injure people, which is safer. The plasma straight-handled cutting gun slides along the limit bar to automatically cut the screen barrel. The stability during cutting is good, and the screen barrel is convenient to clamp. You only need to push the screen barrel between the upper baffle and the steel wire to fix it. The servo motor tightens the steel wire, which greatly improves production efficiency and saves labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

A support column 11 and a cutting beam 12 are fixedly installed on the main frame 1. An upper baffle 7 is rotatably provided on the main frame 1. The upper baffle 7 is connected to the support column 11 through two hydraulic cylinders 10. One end of each hydraulic cylinder 10 is rotatably connected to the support column 11, and the other end is rotatably connected to the upper baffle 7. Two rotating components are provided on the main frame 1, each rotating component includes a wire tensioner 2 rotatably installed on the main frame 1, each wire tensioner 2 is provided with a wire rope 5, and locking components are provided on both sides of the main frame 1. A cutting slide 16 is slidably provided on the cutting beam 12, and a plasma straight-handled cutting gun 15 is provided on the cutting slide 16.

[0023] A cylinder 13 is fixedly installed on the cutting beam 12, and the driving end of the cylinder 13 is fixedly connected to the cutting slide 16. Two limit bars 14 are fixedly connected to the cutting beam 12, and the cutting slide 16 is slidably connected to the two limit bars 14. The cutting length, that is, the distance that the cylinder 13 drives the cutting slide 16 to move, can be set. The cylinder 13 drives the cutting slide 16 to slide along the limit bars 14, and the plasma straight-handled cutting gun 15 will also move stably along with it, and automatically cut the screen barrel 6.

[0024] When the cam 5 is in the upright position, the guide wheels 4 are engaged with the guide wheels 5, and one end of the cam 5 is engaged with the guide wheels 4. When the cam 5 is in the upright position, the guide wheels 4 are engaged with the guide wheels 4, and one end of the cam 5 is engaged with the guide wheels 4. When the cam 5 is in the upright position, the guide wheels 4 are engaged with the guide wheels 4, and one end of the cam 5 is engaged with the guide wheels 4. When the cam 5 is in the upright position, the guide wheels 4 are engaged with the guide wheels 4, and one end of the cam 5 is engaged with the guide wheels 4.

[0025] Two servo motors 8 are fixedly installed on the main frame 1. The driving end of each servo motor 8 is fixedly connected to the corresponding wire tensioner 2. When each servo motor 8 drives the wire tensioner 2 to rotate, the wire rope 5 can be wound. A tension sensor can be set on the wire rope 5. The tension of the wire rope 5 can be transmitted to the PLC system in real time through the tension sensor. According to the size of the real-time tension, the PLC sends a speed instruction to the frequency converter, and the frequency converter controls the tensioning speed of the servo motor 8 by changing the frequency of the servo motor 8.

[0026] After the sieve barrel 6 is in use, one end of the two wire ropes 5 is wound around the outside of the sieve barrel 6, and one end of the wire rope 5 is passed through the through-hole, and then the locking bolt is rotated to make it threadedly connected with the fixing cylinder 3 until one end of the locking bolt extends into the through-hole and one end of the wire rope 5 is fixed and locked, and then the two servo motors 8 are driven to operate at the same time. Since one end of each wire rope 5 away from the fixing cylinder 3 is wound around the corresponding wire tensioner 2 and cannot be separated from the wire tensioner 2, the wire rope 5 can be wound in the process of rotating the wire tensioner 2 driven by each servo motor 8. Under the transmission action of the wire rope 5, the sieve barrel 6 can be driven to move in the direction close to the upper baffle 7 until the sieve barrel 6 is in the right position. On one side of the plasma straight-handled cutting gun 15, the cutting length, that is, the distance that the cylinder 13 drives the cutting slide 16 to move, can be set. The cylinder 13 drives the cutting slide 16 to slide along the limit bar 14. In the process of the plasma straight-handled cutting gun 15 moving together, the screen barrel 6 can be automatically cut. The upper baffle 7 and the lower baffle 9 fully surround the screen barrel 6 in combination with the wire rope 5. After cutting, the screen barrel 6 will not directly bounce off and injure people, and the safety is better. The plasma straight-handled cutting gun 15 slides along the limit bar 14 to automatically cut the screen barrel 6. The stability during cutting is better, and the screen barrel 6 is convenient to clamp. You only need to push the screen barrel 6 between the upper baffle 7 and the wire rope 5 and fix it. The servo motor 8 tightens the wire rope 5, and the production efficiency can be greatly improved while saving manual labor intensity.
