Description

Technical Field

[0002] The spray-gluing flocking line fully automates the entire process, from gluing and flocking to drying and lint removal. It can be applied to a wide variety of surfaces, creating a velvety surface that enhances texture and reduces noise. Suitable materials include, but are not limited to, fabrics, crafts, toys, automotive plastic parts, storage boxes, calendars, couplets, and gift boxes.

[0003] The patent library discloses an automatic amplitude modulation mechanism for a flocking production line and a flocking production line (authorization announcement number CN217963345U), which includes a segmented transmission track, including multiple groups of workstation tracks; multiple groups of track amplitude modulation mechanisms; multiple groups of amplitude modulation drive mechanisms, each of which is connected to the corresponding track amplitude modulation mechanism in a transmission manner, and the amplitude modulation drive mechanism is used to adjust the width of the track amplitude modulation mechanism; and an automatic amplitude modulation synchronous drive mechanism. According to the automatic amplitude modulation mechanism for a flocking production line and a flocking production line of the present invention, when processing products of different specifications, the automatic amplitude modulation synchronous drive mechanism can simultaneously drive each amplitude modulation drive mechanism to rotate, thereby driving the track amplitude modulation mechanism of each workstation track to adjust the width. The effect of synchronous amplitude modulation of the segmented transmission track is achieved, ensuring that the connection accuracy of each workstation track remains unchanged, and there is no need to calibrate the track connection position separately. The track width is uniformly adjusted according to product specifications, saving amplitude modulation labor hours, ensuring stable operation of the production line, and improving production efficiency.

[0004] The automatic amplitude modulation mechanism used in the above-mentioned flocking production can synchronously adjust the track width during use, but it needs to be driven by multiple power sources for adjustment, which increases energy consumption and production costs, and is relatively less practical.

In addition, it can continuously drive the lubricating oil in the oil tank 19 to be delivered to the storage box 24. When it accumulates to a certain level, the oil level sensor 25 detects that it reaches the set value and then opens the one-way valve on the oil pipe 29. The lubricating oil in the storage box 24 can be discharged through the oil pipe 29 and added to the bevel gear 1 11 and the bevel gear 2 12 to lubricate them, reduce their friction and wear, and cool them to dissipate heat and extend their service life.

[0025] In this example, one end of the cover plate 8 is hinged to one end of the transmission case 7, and the other end of the cover plate 8 is connected to the transmission case 7 via a lock, so that the cover plate 8 can be opened to facilitate inspection and maintenance of the internal components of the transmission case 7. In this example, the movable seat 4 is movably mounted on the outside of the screw rod 6 and is movably connected to the screw rod 6. One end of the filter screen 20 is connected to the outside of the oil tank 19 with a handle, and one end of the filter screen 20 is connected to the oil tank 19 via a quick-release bolt, so that the filter screen 20 can be removed, cleaned, or replaced.

The outer wall of the piston 23 is provided with a sealing ring, and the piston 23 is located inside the horizontal portion of the T-shaped tube 21. The inner bottom surface of the transmission case 7 is inclined toward the center to transmit power and improve the sealing between the piston 23 and the T-shaped tube 21. The inclined surface of the inner bottom surface of the transmission case 7 can guide lubricating oil dripping into the transmission case 7 so that it can flow back into the transmission case 7. In this example, the valve component 22 includes a sealing block 26, and the sealing block 26 is fixedly installed in the T-shaped tube 21.

[0026] The working principle of the utility model is as follows: when in use, the distance between the workpiece to be processed and the sensor is detected by the displacement sensor, and then the signal is transmitted to the controller, thereby issuing a command to control the servo motor 9 to work, so that the servo motor 9 drives the rotating shaft 10 to drive the bevel gear 2 12 to rotate, and the bevel gear 2 12 drives the meshing bevel gear 1 11 to drive the screw rod 6 to rotate, thereby synchronously driving multiple movable seats 4 to move. The forward or backward movement of the movable seat 4 can be changed by the forward and reverse rotation of the servo motor 9, and the movement of the movable seat 4 will drive the synchronous movement of one side of the station track 2 connected to it. Thereby changing the width of the track to adapt it to the processing of workpieces of different widths. In addition, the operation of the servo motor 9 will drive the connected sprocket 14 to rotate, and cooperate with the chain 15 to drive another sprocket 14 to drive the reducer 13 to work, so that the output end of the reducer 13 drives the crankshaft 16 to rotate, thereby driving the connecting member 17 to drive the push rod 18 and then push and pull the piston 23 to move back and forth. When the piston 23 moves to the left, the pressure in the T-shaped tube 21 is reduced, so that the sealing plate 27 in the upper valve member 22 is flipped open and the torsion spring 28 is twisted, so that the lubricating oil in the oil tank 19 enters the T-shaped tube 21, then, when the piston 23 moves to the right, the pressure in the T-shaped tube 21 can be increased, the sealing plate 27 in the upper valve member 22 will be reset to close the sealing block 26, and at the same time, the sealing plate 27 in the lower valve member 22 will flip open, so that the lubricating oil in the T-shaped tube 21 is discharged and distributed to the conduit 2 through the three-way valve, and then transported to the storage box 24. When the oil height in the storage box 24 reaches the value set by the oil level sensor 25, a signal can be transmitted to drive the one-way valve on the oil delivery pipe 29 to open through the controller, and at the same time, the one-way valve on the conduit 1 is closed, and the one-way valve on the conduit 2 is closed. When the one-way valve is opened, the subsequent pushed lubricating oil will flow back into the oil tank 19, and the opening of the one-way valve on the oil pipe 29 will discharge the lubricating oil in the oil pipe 29 through the nozzle, thereby adding it to the bevel gear 11 and the bevel gear 2 12, reducing their friction or wear and extending their service life; and when it is necessary to inspect and maintain the internal components of the transmission box 7, the cover 8 can be opened by opening the lock, thereby facilitating the inspection of the internal components of the transmission box 7; the filter 20 is connected to the oil tank 19 by a quick-release bolt, which can facilitate the disassembly of the filter 20 for disassembly, cleaning or replacement, and is more practical.
