DETAILED DESCRIPTION

[0022] In order to make the technical means, creation characteristics, achieve the purpose and function of the utility model easy to understand, the following will be further described in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] The specific embodiments of the utility model will be described below in conjunction with the drawings. Embodiment one:

[0025] Referring to Figures 1-4 An asynchronous induction scrap collecting shaft of a round knife machine, comprising an asynchronous scrap collecting shaft group 1, a processing chamber 9 and a mold material 11, the asynchronous scrap collecting shaft group 1 comprises a machine group board surface 2, a servo motor 3 is installed on one side of the top of the front surface of the machine group board surface 2, a transmission shaft 4 is installed outside the output end of the servo motor 3, the servo motor 3 and the transmission shaft 4 are connected through a shaft coupling, a gas expansion shaft 5 is installed on one side of the front surface of the machine group board surface 2, a guide shaft 6 is installed on the other side of the front surface of the machine group board surface 2, a material pulling shaft 7 is installed at the bottom of the front surface of the machine group board surface 2, the central axes of the material pulling shaft 7 and the transmission shaft 4 are parallel to each other, and the guide shaft 6 is arranged between the material pulling shaft 7 and the transmission shaft 4. Figure 1 The mold material 11 wound outside the material winding disc 8 of the guide shaft 6 is to be processed.

[0026] The asynchronous scrap collecting shaft group 1 comprises the machine group board surface 2, the servo motor 3, the transmission shaft 4, the gas expansion shaft 5, the guide shaft 6 and the material pulling shaft 7, and the transmission shaft 4, the gas expansion shaft 5, the guide shaft 6 and the material pulling shaft 7 are all clamped with the material winding disc 8 outside.

[0027] The asynchronous scrap collecting shaft group 1 is bolted to the back surface of the inner wall of the processing chamber 9, the bottom of the processing chamber 9 is embedded with a base bottom plate 10 on one side, in the middle and on the other side, the top of the base bottom plate 10 is installed with a mounting seat 12, the inside of the mounting seat 12 in the middle is installed with a round knife machine group 13, the round knife machine group 13 is driven by a motor, the top of the round knife machine group 13 is provided with a mounting bayonet 14, and the inside of the mounting bayonet 14 is clamped with a cutter mold 15.

[0028] The three mounting seats 12 are all existing pressing devices, the height of the bottom pressing block is adjusted by the bolts on the top of the two sides, so that the related components are fixed, when the unprocessed mold material 11 passes through the bottom of the round knife machine group 13, the cutter mold 15 on the round knife machine group 13 will press down and cut the mold material 11 after contacting the mold material 11, as shown in the figure, a plurality of mounting bayonets 14 are arranged on the round knife machine group 13, so that a plurality of cutter molds 15 can be installed, and a plurality of cutter molds 15 of different shapes can also be installed. Figure 3

[0029] ​The material 11 is wound on the outer roll plate 8 of the transmission shaft 4 and the outer roll plate 8 of the pulling shaft 7, and the material 11 on the transmission shaft 4 and the pulling shaft 7 passes through the bottom of the cutter set 13 and is closely attached to the bottom of the cutter set 13. The tension control shaft 16 is installed in the mounting seat 12, and the tension control shaft 16 is installed on the three groups of mounting seats 12 according to the actual situation.

[0030] The whole structure cancels the asynchronous mold, and uses the suspended attachment to walk the material. The original finished product cutter mold is unchanged, and the material specification is changed from the original synchronous feeding and whole attachment to two independent controls (such as Figure 1 ), and the material is rolled and cut by the cutter set 13, and the feeding is completed by using the friction and extrusion of the cutter mold foam. The whole asynchronous waste collecting shaft group 1 and the cutter set 13 are inducted to run asynchronously, the spacing of the material is reduced, and the material is saved. Specific embodiment two:

[0032] Referring to Figures 1-4 , in actual operation, the servo motor 3 starts to operate according to the preset program and accurate parameters at the moment of starting the equipment, and the power is stably transmitted to the transmission shaft 4 through the shaft coupling. The transmission shaft 4 drives the material 11 wound on the outer roll plate 8 to start uniform motion, at the same time, the pulling shaft 7 synchronously enters the standby state, and the parallel central axis of the transmission shaft 4 ensures the high stability and accurate linearity of the material 11 in the transmission process. The unprocessed material 11 is drawn out from the outside of the roll plate 8 of the guide shaft 6, accurately passes through the bottom of the cutter set 13 along the preset path and is closely attached. When the material 11 contacts the cutter mold 15 on the cutter set 13, the built-in motor of the cutter set 13 drives the cutter mold 15 to implement the downward cutting operation on the material 11. Because the suspended attachment walking material is used and the material specification is changed to two independent control modes, the material 11 in the rolling and cutting process of the cutter set 13 is assisted to complete the feeding process by the force generated by the friction and extrusion of the cutter mold foam.

[0033] The high-sensitivity tension sensors are equipped on the tension control shaft 16, which can accurately measure the tension of the mold material 11 on the tension control shaft 16 in real time, and convert the tension data into an electrical signal, which is transmitted to the central control system of the device. The control system analyzes and processes the signal according to the preset tension standard range and the current processing process requirements. The tension control shaft 16 in the mounting seat 12 is dynamically and finely adjusted according to the real-time tension condition of the mold material 11. The tension control shaft 16 senses the tension change of the mold material 11 through the high-sensitivity sensor. Once the tension deviates from the preset accurate range, the tension control shaft 16 adjusts the force on the mold material 11 through the internal electromagnetic control device. When the control system determines that the tension needs to be adjusted, it will send a command to the electromagnetic control device. The electromagnetic control device adjusts the magnetic field strength by changing the current flowing through its internal electromagnetic coil. For example, if the tension of the mold material 11 is too small, the control system will instruct the electromagnetic control device to increase the current, thereby increasing the magnetic field strength. The increase of the magnetic field strength will make the electromagnetic control device generate greater electromagnetic attraction or repulsion force on the part of the tension control shaft 16 that contacts the mold material 11, thereby increasing the clamping force or friction force on the mold material 11, and increasing the tension of the mold material 11. Conversely, if the tension is too large, the electromagnetic control device will reduce the current, weaken the magnetic field, and reduce the effect on the mold material 11, so that the tension falls within the appropriate range. This ensures that the mold material 11 always maintains appropriate tension, and prevents problems such as stretching, relaxation, wrinkles, and other problems caused by abnormal tension that affect processing precision. It should be noted that the central tension controller of the electromagnetic control device in the patent No. CN95221515.2 "A reel tension control device" is the same principle, which will not be described in detail here.

[0034] In the entire circular knife machine working system, the asynchronous waste collecting shaft group 1 and the circular knife machine group 13 achieve cooperative work through a special high-frequency induction communication device. The device adopts a hybrid technology of radio frequency identification and near field communication, has excellent signal transmission stability and high-speed processing capability, and ensures accurate and real-time information exchange between the two.

[0035] Need to be explained is that the laser displacement sensor, the pressure sensor and the Hall effect sensor are installed in the circular cutter unit 13, and when the circular cutter unit 13 starts the cutting action, the high-precision laser displacement sensor, the pressure sensor and the Hall effect sensor inside the circular cutter unit 13 work cooperatively to monitor the key parameters in the cutting process in real time. The laser displacement sensor accurately measures the cutting depth of the cutter mold, the pressure sensor monitors the pressure change in real time during cutting, and the Hall effect sensor accurately captures the position information of the cutting cutter mold. Based on these multi-dimensional and high-precision monitoring data, the intelligent master control chip inside the circular cutter unit 13 generates a control signal of a specific format according to a preset algorithm. The signal contains detailed information such as cutting rhythm, force change, mold stress condition and cutting position, and transmits the signal to the asynchronous waste collecting shaft group 1 through a high-frequency induction communication device.

[0036] After receiving the signal, the high-performance programmable logic controller built-in the asynchronous waste collecting shaft group 1 quickly analyzes the signal. After extracting the instruction information related to the material pulling and feeding from the signal, the PLC accurately controls the pulling speed of the pulling shaft 7 and the feeding speed of the transmission shaft 4 according to the instructions. For example, if the cutting rhythm of the circular cutter unit 13 is accelerated, which means that the amount of mold material 11 cut per unit time increases. At this time, the PLC of the asynchronous waste collecting shaft group 1 will adjust the output frequency of the servo driver according to the signal instruction, and correspondingly increase the pulling speed of the pulling shaft 7 and the feeding speed of the transmission shaft 4, to ensure that the mold material can be timely and smoothly supplied to the cutting position, avoiding the situation that the cutting is interrupted or the cutting quality is reduced due to insufficient feeding; on the contrary, if the cutting rhythm is slow, the pulling and feeding speed will also be accurately reduced.

[0037] In summary:

[0038] 1. In the device, the asynchronous waste collecting shaft group 1 is bolted to the back of the inner wall of the machining chamber 9.

When the unprocessed mold material 11 passes through the bottom of the circular cutter unit 13, the cutting tool 15 on the circular cutter unit 13 will press and cut the mold material 11 after contacting the mold material 11, like Figure 3As shown, the circular cutter set 13 is provided with a plurality of mounting sockets 14 for mounting a plurality of cutter dies 15, and a plurality of cutter dies 15 of different shapes can also be mounted, the material winding plate 8 outside the transmission shaft 4 and the material winding plate 8 outside the material pulling shaft 7 are both wound with material 11, the material 11 on the transmission shaft 4 and the material pulling shaft 7 passes through the bottom of the circular cutter set 13 and is attached to the bottom of the circular cutter set 13, and the tension control shaft 16 is installed in the mounting seat 12, and the tension control shaft 16 is installed on the three mounting seats 12 according to the actual situation.
