The PLC controller 28 achieves automated control, executing actions such as rotation angle and pressing according to a pre-programmed language. The control panel's concise and clear design makes it easy for workers to master its operation.

[0037] like Figure 11 、 12 As shown, the heating unit includes a mold positioning plate 17 and a heating element 39. The mold positioning plate 17 is installed on the turntable of the rotation positioning unit by bolts. The heating element 39 is clamped in the bottom groove of the mold positioning plate 17. The lower part is a mica plate. The heating element 39 is provided with a wire interface, and the wire interface is connected to the power supply through an electric heating line. Specifically, in this embodiment, a total of six heating elements 39 are fixed together by high-temperature wires through magnetic columns, and finally two power lines are led out; a mica plate is provided between the bottom surface of the mold positioning plate 17 and the turntable 15 on the rotation positioning unit. The thickness of the mica plate is 2mm and is mainly used for insulation and heat insulation. Specifically, the heating element adopts an aluminum heating plate with high thermal conductivity. The intelligent temperature control instrument makes the temperature stable and reliable and can be observed in real time. The one-button knob control is more convenient; the mold is separated from the heating element, and the mold is easy to replace, which is suitable for heat sealing packaging of products of different models.

[0038] like Figure 1 、 3As shown, two pressing units are symmetrically provided, and the two pressing units are connected to the two ends of the crossbeam 4, and the crossbeam 4 is connected to the top of the column 3, and the column 3 is mounted on the table support frame 2 by bolts. Specifically, the pressing unit includes a driving cylinder 23 and a pressing plate 19. The cylinder 23 is connected to the end face of the crossbeam 4 through a cylinder positioning frame 6. The pressing plate 19 is connected to the concave flange 7 by bolts. The concave flange 7 is connected to the ball head of the connecting ball 25 and is locked in place by the ball head cover 12. The top of the connecting ball 25 is connected to the working rod end face of the cylinder 23 by a threaded connector 26. The cylinder 23 is electrically connected to the PLC controller 28. When working, the cylinder 23 starts to drive the pressing plate 19 below to move up and down linearly through the connecting ball 25, completing the heat pressing operation of the corresponding heat sealing and packaging station below. The cylinder 23 specifically adopts a large-volume cylinder to ensure sufficient and stable pressure. The introduction of the connecting ball 25 realizes a universal pressure head structure, which enables the pressure head and the mold to automatically fit tightly when pressing and heat-sealing, thereby ensuring the quality of heat sealing.

[0039] like Figure 3 、 4 , 5, and 6, the rotation positioning unit includes a servo motor 29 and a turntable 15. The servo motor 29 is installed on the top bottom surface of the frame 1 through a servo motor positioning plate 30. The working shaft of the servo motor 29 passes through the servo motor positioning plate 30 and is connected to a driving gear 38. The driving gear 38 is meshed with the second spur gear. The second spur gear is rotatably mounted on the bottom of the gear shaft 32 through a bearing 31. The top of the gear shaft 32 is connected to the first spur gear 24 and is locked in position through a gear shaft pressure cover 33. The first spur gear 24 is meshed with the ring gear, and the ring gear is mounted on the The bottom of the turntable 15 is located near the periphery; the servo motor 29 is electrically connected to the PLC controller 28; the turntable 15 is connected to the turntable main shaft 14 by screws and is located in the through hole of the table 8, the turntable main shaft 14 is connected to the table support frame 2 through the support plate 11, and a rotating component is provided between the turntable main shaft 14 and the support plate 11; a guard plate assembly 34 is provided above the turntable 15, and a plurality of heat sealing and packaging stations are provided on the guard plate assembly 34, one of which is located directly below the pressing unit, and the heating unit is installed between the guard plate assembly and the turntable 15. Specifically, as Figure 9 As shown, the turntable main shaft 14 is configured as a hollow multi-step cylindrical structure.

[0040] During operation, the servo motor 29 is started, and the driving gear connected to the end is driven to rotate through the working shaft of the servo motor 29. Since the driving gear is engaged with the second spur gear, the second spur gear and the first spur gear 24 are simultaneously installed at the bottom of the gear shaft 32, and the first spur gear 24 is engaged with the ring gear. The turntable is then driven to rotate through the ring gear. The angle of each rotation of the turntable 15 is set to 60° according to the actual rotation ratio, that is, the servo motor 29 drives the turntable 15 to rotate each time it works to realize the replacement of the heat sealing packaging station. After one rotation, the servo motor 29 rotates in the opposite direction to realize the replacement of the six heat sealing packaging stations.

[0041] Specifically, such as Figure 6 As shown, the rotating assembly includes a rolling bearing 13, which is installed in the bearing sleeve 10 and the end is sealed and positioned by the bearing cover 9. A bearing spacer 16 is provided between the two rolling bearings 13, and the turntable main shaft 14 rotates around the rolling bearing 13 driven by the turntable 15.

[0042] like Figure 6 、 10 As shown, the bottom of the turntable spindle 14 is connected to a rotor 21. A carbon brush is installed on one side of the rotor 21. The carbon brush is mounted on a carbon brush positioning bracket 20, which is bolted to both sides of the frame 1. During processing, the turntable is equipped with six heat-sealing and packaging stations, each with a heating element. The six heating elements share a set of power cables (two wires) and a temperature measuring element (thermocouple, two wires). A ground wire is connected to the turntable. The spindle is designed as a hollow structure. These five wires are connected to the rotor of the conductive slip ring below through the center hole of the spindle, forming a relatively static structure. The rotor of the conductive slip ring contacts the carbon brush on one side to transmit signals and current. The conductive slip ring can transmit 220V heating power and 12V control signal power.

[0043] like Figure 7 、 8 As shown, the guard plate assembly 34 is provided with six heat sealing and packaging stations and is evenly distributed around the circumference. The guard plate assembly 34 includes a circular guard plate body 34-1 and a plurality of positioning blocks 34-4. The plurality of positioning blocks 34-4 are regularly arranged and connected to the top surface of the guard plate body 34-1 to form six heat sealing and packaging stations. A mold positioning plate 17 is installed on each heat sealing and packaging station, and a mold 18 is placed in each mold positioning plate 17. When working, a PVC film, a diamond saw blade, a gasket and a cardboard 34-2 are placed on each mold 18.

[0044] Specifically, a circular gasket tray 34 - 3 is connected to the center of the top surface of the guard plate body 34 - 1 . The gasket tray 34 - 3 is configured as a disc with a U-shaped cross section, and a plurality of gaskets are placed in the disc.

[0045] The working process of the present invention is as follows:

[0046] Step 1, preparation: Connect a multi-station rotary diamond saw blade heat-sealing packaging machine to the power supply, set the corresponding operating parameters, including heat-sealing time and heat-sealing temperature, etc. through the control panel 27, and then install the corresponding mold 18 into the mold installation slot 40. Place the PVC film (positioned by the mold), diamond saw blade, gasket, and cardboard 34-2 (the surface of the cardboard is coated with special hot melt adhesive) on the mold from bottom to top. The advantage of this placement is that the hot pressing process first allows the connection between the PVC film and the cardboard to directly conduct heat through the mold to achieve the best thermal adhesion. Only then can the cylinder 23 drive the pressing plate 19 to descend for pressing, thereby completing the saw blade packaging process. The specific mold 18 uses an aluminum mold with good thermal conductivity, which heats more evenly and has a good thermal bonding effect.

[0047] Step 2: Heating unit operation: Press the heating knob on the control panel 27, and the heating element 39 starts and runs according to the setting for the specified time. When the heating temperature reaches the set value, the heating indicator light lights up and transmits the signal to the PLC controller 28. Specifically, turn the heating knob on the control panel 27 to the on position, and the red heating indicator light lights up. Six aluminum heating plates of the same specifications begin heating simultaneously, and the thermocouple transmits the signal to the PLC controller. The temperature displayed by the thermostat continues to rise. When the temperature reaches the set temperature, the thyristor controls the heating element 39 to stop heating. The heating and stopping of the heating element are automatically controlled by the program settings in the PLC controller, so that the temperature is always stable at the set temperature.

[0048] Step 3, pressing unit operation: When the heating temperature reaches the set value, the PLC controller 28 sends a command to the cylinder 23, and the working rod of the cylinder 23 extends downward, driving the lower pressing plate 19 to move downward and press on the PVC film through the connecting ball 25. After pausing for the set time value, it moves upward in the opposite direction to reset; completing the hot pressing operation of the diamond saw blade on the corresponding heat sealing packaging station below.

[0049] Step 4, rotation and positioning unit operation: After the cylinder 23 is completely reset, the PLC controller 28 receives the signal and issues a rotation command. At this time, the servo motor 29 is started, and the working shaft of the servo motor 29 drives the driving gear connected to the end to rotate. The driving gear drives the ring gear to rotate through the second spur gear and the first spur gear 24, thereby driving the turntable 15 to rotate. According to the actual rotation ratio, the angle of each rotation of the turntable 15 is set to 60°, and the next heat sealing packaging station is rotated to the bottom of the pressing unit to realize a new heat sealing packaging operation of the diamond saw blade.

[0050] In general, the multi-station rotary diamond saw blade heat-sealing packaging machine of the present invention is applied by repeating steps 2-4 to achieve the heat-sealing packaging operation of multiple groups of diamond saw blades. The equipment comprises two symmetrical pressing units and two rotary positioning units, each of which is provided with six stations. A single operation can achieve the heat-sealing packaging operation of 12 diamond saw blades. The equipment uses manual loading and realizes automated control of heating, pressing, and position change via a PLC controller, resulting in high work efficiency. Specifically, the six stations heat simultaneously. When starting operation, the heating knob is first turned on. After the temperature reaches the set value, the turntable rotation knob is turned on to start operation. When stopping operation, the turntable rotation knob is first turned off, followed by the heating knob.

[0051] Through the description of the above assembly principle combined with the existing PLC programming technology, it is entirely possible to realize the automatic control of the multi-station rotary diamond saw blade heat sealing packaging machine, so it will not be described in detail here.

[0052] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
