Description

Technical Field

[0001] The utility model relates to the technical field of mask production equipment, in particular to a flattening device for mask production and processing. Background Technique

[0002] A mask is a hygiene and epidemic prevention product that can block harmful gases, odors, droplets, viruses and other substances. Flattening is an important link in the mask production process. Generally, three groups of flattening rollers are used to roll the raw materials to form and fix the folds, which is convenient for subsequent slicing and gluing.

[0003] Most of the commonly used mask production and processing flattening devices on the market are similar in structure. An electric motor drives three groups of driving rollers to rotate continuously. There is a flattening roller on the top of the driving roller. The blank of the mask is shaped by the pressing force between the upper and lower rollers. In the actual use process, there are some functional deficiencies and there is room for improvement. For example, the electric motor is connected to the roller through transmission components such as chains and sprockets. As the service life increases, it is necessary to regularly open the protective cover to lubricate the sprockets and chains, and the overall operation is relatively troublesome and does not have the function of facilitating oiling and maintenance. Secondly, the pressure of the rollers of the current mask flattening equipment on the market is mostly adjusted manually. By rotating the screw rod to drive the flattening roller up and down, the actual pressure between the upper and lower groups of rollers cannot be intuitively understood. If it is too loose, the pressing effect is poor. If it is too tight, the blank is easily deformed and damaged, and it does not have the function of pressure value feedback.

[0004] Now, a new type of mask production and processing flattening device is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flattening device for mask production and processing to solve the problem of not having the function of facilitating oiling and maintenance mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A flattening device for mask production and processing, including a main fixing plate. A concave frame is fixedly connected to the middle position of the top of the main fixing plate. Three groups of bottom supporting rollers are longitudinally movably connected between the front and rear ends inside the concave frame. A transmission sprocket is fixedly connected to the outside of the rear end of the bottom supporting roller. A transmission chain is sleeved on the outside of the transmission sprocket. An outer protective cover is fixedly connected to the bottom of the rear end of the concave frame. Square fixing tubes are respectively vertically fixedly connected to the four corners of the bottom of the main fixing plate. A bearing plate is horizontally fixedly connected between one sides of the square fixing tubes. Three groups of fixing seats are respectively fixedly connected to the front and rear ends of the top of the concave frame. An adjusting block is arranged below the fixing seat. A pressure sensor is installed at the middle position of the top of the adjusting block. An extension leg is inserted into the bottom end of the square fixing tube from bottom to top. An automatic oiling and maintenance mechanism is arranged on the top of the bearing plate.

[0007] The automatic oiling and maintenance mechanism includes an oil storage box fixedly connected to one side of the top of the bearing plate. A metering pump is arranged on the left side of the oil storage box. An oil delivery pipe is arranged above the outer protective cover, and three drip nozzles are installed at the bottom of the oil delivery pipe.

[0008] Preferably, one side of the oil delivery pipe is connected to one side of the metering pump, and the oil storage box, the metering pump, and the oil delivery pipe are connected.

[0009] Preferably, the bottom end of the drip nozzle penetrates through the top end of the outer protective cover and extends into the interior, and the bottom end of the drip nozzle is higher than the top end of the transmission chain.

[0010] Preferably, a driving motor is installed at the rear end of the bottom of the main fixing plate. The driving motor and the transmission gear disk are connected by a transmission chain, and the vertical center lines of the transmission gear disk and the drip nozzle coincide.

[0011] Preferably, a first electric cylinder is installed on the top of the fixed seat. The bottom end of the first electric cylinder penetrates through the interior of the fixed seat and is connected to the top end of the pressure sensor.

[0012] Preferably, a pressing roller is movably connected between one ends of the two adjusting blocks. A liquid crystal display screen is installed at the front end of the fixed seat, and the liquid crystal display screen is electrically connected to the pressure sensor.

[0013] Preferably, the outer diameter of the extension leg is consistent with the inner diameter of the square fixing pipe, and the extension leg can slide up and down along the interior of the square fixing pipe.

[0014] Preferably, multiple positioning screw holes are arranged at one end of the extension leg. A positioning bolt is inserted into the bottom of one end of the square fixing pipe. A second electric cylinder is installed inside the extension leg. The positioning bolt penetrates through one end of the square fixing pipe and extends into the positioning screw holes, and the positioning screw holes are arranged at equal intervals.

[0015] Compared with the prior art, the beneficial effects of the present utility model are that the flattening device for mask production and processing not only realizes the function of facilitating oiling and maintenance, but also realizes the function of pressure value feedback, and also realizes the function of facilitating the adjustment of the equipment height;

[0016] By providing an oil storage box, a metering pump, an oil delivery pipe, and a nozzle, during use, the driving motor drives the bottom supporting rollers to rotate continuously through a transmission chain and a transmission gear disc. The bottom supporting rollers are driven by the transmission gear disc and the transmission chain, and the three groups of bottom supporting rollers rotate synchronously. The blank of the mask passes between the bottom supporting rollers and the pressing rollers and is shaped by being squeezed by the two groups of rollers.

The downward pressure of the pressing roller depends on the thrust received by the adjusting block. When the first electric cylinder on the fixed seat extends downward, the pressure increases, and when it retracts upward, the pressure decreases. The pressure sensor can directly monitor the pressure value and feedback it through the liquid crystal display screen, facilitating the user to view and refer to it, thus realizing the function of pressure value feedback;

[0018] By providing extension legs, positioning screw holes, positioning bolts, and a second electric cylinder, during use, when it is necessary to adjust the height of this equipment according to the actual height and specifications of other equipment on the same production line, first loosen and remove the positioning bolt, then start the second electric cylinder inside the extension leg. The second electric cylinder extends or retracts, and through the reaction force, the main fixed plate and the square fixed pipe can slide up and down along the outside of the extension leg. After adjusting to the appropriate height, reinsert the positioning bolt, and when the positioning bolt is inserted into the positioning screw hole, the height is fixed, thus realizing the function of convenient adjustment of the equipment height.

A bearing plate 8 is horizontally fixedly connected between one sides of the square fixing pipes 7. An automatic oiling and maintenance mechanism is arranged on the top of the bearing plate 8;

[0027] Please refer to Figures 1-5 , a flattening device for mask production and processing further includes an automatic oiling and maintenance mechanism. The automatic oiling and maintenance mechanism includes an oil storage box 9. The oil storage box 9 is fixedly connected to one side of the top of the bearing plate 8. A metering pump 10 is arranged on the left side of the oil storage box 9. An oil delivery pipe 11 is arranged above the outer shield 6. Three groups of drip nozzles 12 are installed at the bottom of the oil delivery pipe 11;

[0028] One side of the oil delivery pipe 11 is connected to one side of the metering pump 10. The oil storage box 9, the metering pump 10, and the oil delivery pipe 11 are connected. The bottom end of the drip nozzle 12 penetrates through the top end of the outer shield 6 and extends to the inside. The bottom end of the drip nozzle 12 is higher than the top end of the driving chain 5. A driving motor 13 is installed at the rear end of the bottom of the main fixed plate 1. The driving motor 13 and the driving gear disk 4 are connected by the driving chain 5. The vertical center lines of the driving gear disk 4 and the drip nozzle 12 coincide, which is convenient for quick oiling and maintenance without disassembling the cover;

[0029] Specifically, as Figure 1 ,Figure 2 and Figure 4 As shown in Figure 4 , start the metering pump 10. The metering pump 10 pumps out a certain amount of oil from the oil storage box 9 and transports it to the nozzle 12 through the oil delivery pipe 11. The three groups of nozzles 12 drip oil onto the transmission gear disk 4 below. As the transmission gear disk 4 rotates, the oil contacts the chain fully, and there is no need to disassemble or assemble the outer cover 6.

[0030] Embodiment 2: Three groups of fixed seats 14 are respectively fixedly connected to the front and rear ends of the top of the concave frame 2. An adjusting block 18 is arranged below the fixed seat 14. A pressure sensor 17 is installed at the middle position of the top of the adjusting block 18. A first electric cylinder 15 is installed on the top of the fixed seat 14. The bottom end of the first electric cylinder 15 penetrates through the inside of the fixed seat 14 and is connected to the top end of the pressure sensor 17. A pressing roller 19 is movably connected between one ends of the two groups of adjusting blocks 18. A liquid crystal display screen 16 is installed at the front end of the fixed seat 14. The liquid crystal display screen 16 is electrically connected to the pressure sensor 17, which can intuitively feedback the pressure value and is convenient for the operator to refer to and adjust.

[0031] Specifically, as Figure 1 and Figure 3 shown in Figure 3 , the downward pressure of the pressing roller 19 depends on the thrust received by the adjusting block 18. When the first electric cylinder 15 on the fixed seat 14 extends downward, the pressure increases, and when it retracts upward, the pressure decreases. The pressure sensor 17 can directly monitor the pressure value and feedback it through the liquid crystal display screen 16, which is convenient for the user to view and refer to.

[0032] Embodiment 3: An extension leg 20 is inserted into the bottom end of the square fixed tube 7 from bottom to top. The outer diameter of the extension leg 20 is consistent with the inner diameter of the square fixed tube 7. The extension leg 20 can slide up and down along the inside of the square fixed tube 7. One end of the extension leg 20 is provided with multiple groups of positioning screw holes 21. A positioning bolt 22 is inserted into the bottom of one end of the square fixed tube 7. A second electric cylinder 23 is installed inside the extension leg 20. The positioning bolt 22 penetrates through one end of the square fixed tube 7 and extends into the inside of the positioning screw hole 21. The positioning screw holes 21 are arranged at equal intervals, which is convenient for adjusting the height of the equipment to match other equipment on the production line.

[0033] Specifically, as Figure 1 and Figure 5 shown in Figure 5 , loosen and remove the positioning bolt 22, then start the second electric cylinder 23 inside the extension leg 20. The second electric cylinder 23 extends or retracts. Through the reaction force, the main fixed plate 1 and the square fixed tube 7 can slide up and down along the outside of the extension leg 20. After adjusting to the appropriate height, reinsert the positioning bolt 22. When the positioning bolt 22 is stuck into the positioning screw hole 21, the height is fixed.

[0034] Working principle: When the utility model is in use, first, the driving motor 13 drives the bottom supporting rollers 3 to rotate continuously through the transmission chain 5 and the transmission gear disc 4. The bottom supporting rollers 3 are driven by the transmission gear disc 4 and the transmission chain 5, and the three groups of bottom supporting rollers 3 rotate synchronously. The blank of the mask passes between the bottom supporting rollers 3 and the pressing roller 19 and is shaped by being squeezed by the two rollers. The transmission gear disc 4 and the transmission chain 5 are used as transmission components and need to be lubricated regularly. When lubricating, start the metering pump 10. The metering pump 10 pumps out a certain amount of oil from the oil storage box 9 and transports it to the nozzle 12 through the oil delivery pipe 11. The three nozzles 12 drip oil onto the transmission gear disc 4 below. As the transmission gear disc 4 rotates, the oil contacts the chain fully, and there is no need to disassemble and assemble the outer cover 6. The blank of the mask passes between the bottom supporting rollers 3 and the pressing roller 19. The downward pressure of the pressing roller 19 depends on the thrust received by the adjusting block 18. When the first electric cylinder 15 on the fixed seat 14 extends downward, the pressure increases, and when it retracts upward, the pressure decreases. The pressure sensor 17 can directly monitor the pressure value and feedback it through the liquid crystal display screen 16, which is convenient for the user to view and refer to. When it is necessary to adjust the height of this equipment according to the actual height and specifications of other equipment on the same production line, first loosen and remove the positioning bolt 22, and then start the second electric cylinder 23 inside the extension leg 20. The second electric cylinder 23 extends or retracts, and through the reaction force, the main fixing plate 1 and the square fixing pipe 7 can slide up and down along the outside of the extension leg 20. After adjusting to the appropriate height, reinsert the positioning bolt 22, and when the positioning bolt 22 is inserted into the positioning eye 21, the height is fixed.
