Description

Technical Field

[0001] This utility model relates to the field of magnetic strip processing technology, and more specifically, to a cutting device for an automatic magnetic strip slitting machine. Background Technology

[0002] Magnetic strips are typically made of multiple layers of composite materials. The core is a magnetic material layer, usually made of ferrite, cobalt-nickel alloys, or other materials with good magnetic properties. These magnetic materials can store magnetic information. The outer layer often has a protective coating that isolates the strip from the external environment, prevents wear, and avoids interference with the magnetic properties, allowing it to function in a relatively stable state.

[0003] Magnetic strip cutting is a processing operation that divides continuous magnetic strip materials into sections according to specific dimensions and specifications. As a crucial component of the magnetic strip production line, the existing magnetic strip cutting device typically uses a cylinder assembly for lifting and cutting. However, fluctuations in air pressure during cylinder operation and wear of seals can easily lead to slight variations in the stroke of each cutting action, and the built-in structure is extremely inconvenient to maintain. Therefore, we propose an automatic magnetic strip slitting machine cutting device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a cutting device for an automatic magnetic stripe cutting machine to solve the technical problems of inconvenient debugging and inconvenient replacement of consumables in the current cylinder-controlled cutting operation.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a magnetic strip automatic slitting machine cutting device, including a cutting mechanism, the cutting mechanism including an assembly table installed on the production line, a guide table fixed in the middle of the assembly table, a cutting component eccentrically mounted on the inner side of the assembly table, and a lifting component and a driving component fixed on the upper end of the assembly table. The assembly table includes a base plate fixed on the production line panel, vertical plates fixed longitudinally on both sides of the base plate, a horizontal plate connected and fixed between the two vertical plates, and a top plate fixed at the top of the vertical plates. The cutting component includes a rocker arm transversely inserted between the two vertical plates, an adjustment port opened at one end of the rocker arm, a sliding groove through the rocker arm and connected at one end to the adjustment port, and a synchronous arm slidably installed in the sliding groove. The lifting component includes a piston cylinder through the top plate, a piston rod slidably through the piston cylinder, a frame fixed at the bottom of the piston rod, and a fixing plate fixed at the top of the piston rod.

[0006] Preferably, the production line is divided into sections, including a material storage area, a winding mechanism, a tape mechanism, a coding mechanism, and a feeding mechanism, with the cutting mechanism located between the tape mechanism and the coding mechanism.

[0007] Preferably, the upright plate has an opening, and a bearing seat is provided on the outside of the opening on one side of the upright plate. After the rocker arm passes through the opening, one end is rotatably mounted on the bearing seat.

[0008] Preferably, the rocker arm has an assembly opening on its front side, and a cutting tool is fixedly installed in the assembly opening by an assembly piece. The assembly piece has an insertion rod, the cutting tool has an insertion hole, and the insertion rod is inserted into the insertion hole.

[0009] Preferably, the outer end of the synchronizing arm is located inside the adjustment port, the synchronizing arm is L-shaped, and the inner end face of the bent part of the synchronizing arm is fixedly connected to the inside of the sliding groove by a spring. A pressure rod is rotatably installed at the bottom of the sliding groove by a rotating shaft, and the inner end of the synchronizing arm corresponds to the upper end of the pressure rod.

[0010] Preferably, the frame is provided with a positioning shaft, which is slidably installed in the adjustment port. The upper end of the piston rod is sleeved with a second spring, and the two ends of the second spring are connected to the piston cylinder and the fixing plate.

[0011] Preferably, the drive assembly includes a motor fixed to the top plate, a shaft passing through one side of the upright plate, a bushing sleeve fixed to the shaft, and a cam inserted into the outside of the bushing sleeve. A limit nut is threaded on the outside of the shaft, and the output shaft of the motor and the outer end of the shaft are connected by a synchronization assembly.

[0012] Preferably, the synchronization component consists of two synchronization pulleys and a timing belt for transmission, and the synchronization component is located on the rear side of the assembly table.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. When this utility model is working, the cam of the drive component presses down on the rocker arm of the cutting component to deflect it, so that the cutter cuts the magnetic strip passing through the guide table. The continuous rotation of the cam completes the repeated cutting action of the cutter, realizing assembly line operation. Compared with the existing cylinder drive method, the rotation angle and speed are accurately controlled by the preset parameters of the motor. Combined with the specific contour curve of the cam, the axial displacement of the cutter can be precisely controlled. Compared with the cylinder drive method, which is limited by the piston stroke accuracy and air pressure stability, the accuracy of stroke control is poor. At the same time, the consumables such as the cylinder seal ring are installed internally, making maintenance more difficult.

[0014] 2. During the cutting action of this utility model, the top of the rocker arm deflects and descends. Due to the axial rotation, the connection position between the rocker arm and the positioning shaft changes. The positioning shaft moves and squeezes within the adjustment port, causing the synchronous arm to move synchronously. The inner end of the synchronous arm pushes the upper end of the pressure rod, causing it to deflect. The lower end of the pressure rod pushes the side of the magnetic strip passing through the guide table from one side, so that the magnetic strip is aligned and fixed to one side of the guide groove. Through the above-mentioned synchronous structure, the magnet is fixed first during the cutting action to prevent the magnetic strip from moving during the oblique cutting process due to the width of the guide groove being greater than the magnetic strip, thus affecting the flatness of the cut surface and ensuring product quality.

[0017] like Figures 1 to 5As shown, the present invention relates to an automatic magnetic stripe slitting machine cutting device, including a cutting mechanism 5. The cutting mechanism 5 includes an assembly table 11 installed on the production line 1, a guide table 10 fixed in the middle of the assembly table 11, a cutting component 9 eccentrically mounted on the inner side of the assembly table 11, and a lifting component 8 and a driving component 12 fixed on the upper end of the assembly table 11. The assembly table 11 includes a base plate 1106 fixed on the panel of the production line 1, vertical plates 1101 longitudinally fixed on both sides of the base plate 1106, a horizontal plate 1102 connecting and fixed between the two vertical plates 1101, and a top plate 1105 fixed at the top of the vertical plates 1101. The production line 1 is divided into sections, including a storage area 2, a winding mechanism 3, a tape mechanism 4, a coding mechanism 6, and a feeding mechanism 7. The cutting mechanism 5 is located between the tape mechanism 4 and the coding mechanism 6. An opening 110 is provided on the vertical plate 1101. 4. A bearing seat 1103 is provided on the outer side of the opening 1104 of the upright plate 1101. After the rocker arm 901 passes through the opening 1104, one end is rotatably mounted on the bearing seat 1103. During operation, the cam 1205 of the drive assembly 12 presses down on the rocker arm 901 of the cutting assembly 9 to deflect it, so that the cutter 909 cuts the magnetic strip passing through the guide table 10. The continuous rotation of the cam 1205 completes the repeated cutting action of the cutter 909, realizing assembly line operation. Compared with the existing cylinder drive method, the rotation angle and speed are accurately controlled by the preset parameters of the motor 1201. Combined with the specific contour curve of the cam 1205, the axial displacement of the cutter 909 can be precisely controlled. Compared with the cylinder drive method, which is limited by the piston stroke accuracy and air pressure stability, the accuracy of stroke control is poor. At the same time, the consumables such as the cylinder seal ring are installed internally, making maintenance more difficult.

[0018] like Figures 4 to 10As shown, the present invention relates to an automatic magnetic stripe slitting machine cutting device, including a cutting mechanism 5, a cutting assembly 9 including a rocker arm 901 transversely inserted between two vertical plates 1101, an adjustment port 902 opened at one end of the rocker arm 901, a sliding groove 911 penetrating inside the rocker arm 901 and connected at one end to the adjustment port 902, and a synchronous arm 903 slidably installed in the sliding groove 911, a lifting assembly 8 including a piston cylinder 802 penetrating on a top plate 1105, a piston rod 801 slidably penetrating inside the piston cylinder 802, a frame 803 fixed to the bottom of the piston rod 801, and a fixing piece 806 fixed to the top of the piston rod 801, an assembly port 905 opened on the front side of the rocker arm 901, and a component fixedly installed in the assembly port 905 by the assembly piece 906. The cutting tool 909 has an insertion rod 907 on the assembly piece 906, and the cutting tool 909 has an insertion hole 908. The insertion rod 907 is inserted into the insertion hole 908. During the cutting action, the top of the rocker arm 901 deflects and descends. Due to the axial rotation, its connection position with the positioning shaft 804 changes. The positioning shaft 804 moves and squeezes within the adjustment port 902, causing the synchronous arm 903 to move synchronously. The inner end of the synchronous arm 903 pushes the upper end of the pressure rod 904, causing it to deflect. The lower end of the pressure rod 904 pushes the side of the magnetic strip passing through the guide table 10 from one side, so that the magnetic strip is aligned and fixed to one side of the guide groove 1002. Through the above-mentioned synchronous structure, the magnet is fixed first during the cutting action to prevent the magnetic strip from moving during the oblique cutting process due to the width of the guide groove 1002 being greater than the magnetic strip, thus affecting the flatness of the cut surface and ensuring product quality.

[0019] Preferably, the outer end of the synchronizing arm 903 is located inside the adjusting port 902. The synchronizing arm 903 is L-shaped, and the inner end face of the bent portion of the synchronizing arm 903 is fixedly connected to the inside of the sliding groove 911 by a spring 910. A pressure rod 904 is rotatably mounted on the bottom of the sliding groove 911 via a rotating shaft, and the inner end of the synchronizing arm 903 corresponds to the upper end of the pressure rod 904. A positioning shaft 804 is provided inside the frame 803, and the positioning shaft 804 is slidably mounted inside the adjusting port 902. A second spring 805 is sleeved on the upper end of the piston rod 801, and the two ends of the second spring 805 are connected to the piston cylinder 802 and the fixed... The drive assembly 12 includes a motor 1201 fixed on the top plate 1105, a shaft 1203 passing through one side plate 1101, a bushing 1204 sleeved and fixed on the shaft 1203, and a cam 1205 inserted into the outside of the bushing 1204. A limit nut is threaded on the outside of the shaft 1203. The output shaft of the motor 1201 and the outer end of the shaft 1203 are connected by a synchronization assembly 1202. The synchronization assembly 1202 consists of two synchronization pulleys and a synchronous belt for transmission. The synchronization assembly 1202 is located behind the assembly table 11.

[0020] Working Principle: This embodiment provides an automatic magnetic strip slitting machine cutting device. During operation, the cam 1205 of the drive assembly 12 presses down on the rocker arm 901 of the cutting assembly 9, causing it to deflect. This causes the cutter 909 to cut the magnetic strip passing through the guide table 10. The continuous rotation of the cam 1205 completes the repeated cutting action of the cutter 909, realizing assembly line operation. Compared with the existing cylinder-driven method, during the cutting action, the top of the rocker arm 901 deflects and descends. Due to axial rotation, its connection position with the positioning shaft 804 changes. The positioning shaft 804 moves and squeezes within the adjustment port 902, causing the synchronous arm 903 to move synchronously. The inner end of the synchronous arm 903 pushes the upper end of the pressure rod 904, causing it to deflect. The lower end of the pressure rod 904 pushes the side of the magnetic strip passing through the guide table 10 from one side, so that the magnetic strip is aligned and fixed to one side of the guide groove 1002. Through the above-mentioned synchronous structure, the magnet is fixed before the cutting action, preventing the magnetic strip from moving during the oblique cutting process due to the width of the guide groove 1002 being greater than the magnetic strip, thus affecting the flatness of the cut surface and ensuring product quality.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations.
