Description

Technical Field

[0001] The utility model belongs to the technical field of PVC glove production equipment, and in particular relates to a dust removal device for PVC glove production equipment. Background Art

[0002] PVC gloves are polymer plastic gloves and are the fastest growing product in the protective gloves industry. Medical staff and food industry service personnel choose this product because PVC gloves are comfortable to wear, flexible to use, do not contain any natural latex ingredients, and will not cause allergic reactions. During the production process of PVC gloves, a certain amount of dust is often generated, which requires dust removal.

[0003] For example, the Chinese patent with the announcement number CN216572097U discloses a dust removal device for PVC glove production equipment, including a dust removal device body, an air outlet pipe, a dust filter plate, a connecting plate, a motor, a scraper, a cleaning brush, a connecting pipe, a base plate, a dust collecting box, a pull plate, a collecting box and an air filter plate, wherein the air outlet pipe is connected to the top of the right side of the dust removal device body, the dust filter plate is fixedly connected to the right side of the inner wall of the air outlet pipe, the connecting plate is fixedly connected to the top and bottom of the inner wall of the air outlet pipe, the motor is fixedly connected to the opposite side of the connecting plate, the scraper is fixedly connected to the right side of the motor, the cleaning brush is fixedly connected to the right side of the scraper, the right side of the cleaning brush contacts the left side of the dust filter plate, and the connecting pipe is connected to the front of the air outlet pipe. The utility model solves the problem that the existing dust removal device directly discharges air in the air outlet area, the dust intercepted by the dust removal device will be directly discharged, and the dust removal effect is not improved.

[0004] This patent has some shortcomings when in use, such as: the device in this patent simply filters the exhaust gas by setting a dust filter plate at the outlet pipe, and then rotates the cleaning brush on the inner side of the dust filter plate to remove the dust remaining on the dust filter plate. When the cleaning brush scrapes the dust filter plate to remove the dirt, some dust may still escape to the outside through the dust filter plate, making the overall dust removal effect poor. In addition, when the device in this patent cleans the dust in the collection box, it cannot operate without stopping the machine, resulting in problems such as line stoppage and shutdown in the production of PVC gloves, affecting production efficiency. In view of this, we propose a dust removal device for PVC glove production equipment. Utility Model Content

[0042] Embodiment 1:

[0043] See also Figure 1 - Figure 5 As shown, this embodiment provides a dust removal device for PVC glove production equipment, comprising:

[0044] The air inlet duct 1 is in a Y-shaped structure, and one of them is an air inlet end, and the other two are symmetrically arranged air outlet ends. The two air outlet ends of the air inlet duct 1 are both provided with a dust removal box 2, and a partition 6 is fixed in the dust removal box 2, and the partition 6 divides the inner cavity of the dust removal box 2 into an upper insulating layer and a lower dust removal layer, and a discharge port is opened on the side wall of the dust removal box 2 near the bottom;

[0045] A collecting box 13, the collecting box 13 is slidably mounted at the discharge port of the dust removal box 2;

[0046] The dust filter 7 is arranged in the dust removal layer of the dust filter 7, and fixed plates 8 fixed to the inner wall of the dust removal box 2 are symmetrically arranged on both sides of the dust filter 7, and a plurality of evenly distributed soft brushes 9 are fixed on the fixed plates 8;

[0047] Exhaust duct 10, the exhaust duct 10 is arranged just above the dust removal box 2, and the bottom end of the exhaust duct 10 passes through the upper surface of the dust removal box 2 and the upper surface of the partition 6 in sequence and extends to the dust removal layer of the dust removal box 2 and is fixed to the dust removal filter 7, the dust removal filter 7 is hollow cylindrical and is connected to the exhaust duct 10, the dust removal filter 7 is located just above the collection box 13, and the top of the exhaust duct 10 is fixed with a fan 11 by bolts;

[0048] A driving assembly, the driving assembly is located in the insulating layer of the dust filter 7 and is used to drive the exhaust pipe 10 and the dust filter 7 to rotate;

[0049] Two holders 3 are fixedly mounted at the center of the end of the air inlet end of the air inlet pipe 1. A reversing plate 4 is rotatably mounted between the two holders 3. A knob 5 is arranged above the air inlet pipe 1. The bottom end of the knob 5 sequentially penetrates the upper surface of the air inlet pipe 1 and the holder 3 located above and is fixed to the reversing plate 4.

[0050] Three limit assemblies are all located on the upper surface of the air inlet pipe 1 and are used to constrain and limit the rotation direction of the reversing plate 4.

[0051] The air inlet end of the air inlet pipe 1 is fixed to the air outlet of the main body of the PVC glove production equipment. In the initial state, the reversing plate 4 is in a horizontal state and is constrained by the limit assembly located in the middle. At the same time, the fans 11 on the two dust removal boxes 2 are started. At this time, the dust-containing gas enters the inner cavity of the two dust removal boxes 2 along the two air outlet ends of the air inlet pipe 1. It is worth noting that the air outlet end of the air inlet pipe 1 penetrates the outer wall of the dust removal box 2 and is connected to the dust removal layer of the dust removal box 2. The dust-containing gas passes through the dust removal filter 7 and enters the exhaust pipe 10. In this process In the process, the dust and large particles in the gas will be blocked by the dust filter 7, the driving component is started, and the driving component drives the exhaust pipe 10 and the dust filter 7 to rotate. During the rotation of the dust filter 7, the circumferential wall of the dust filter 7 is constantly in contact with the soft brushes 9 on both sides, and the dust accumulated on the circumferential wall of the dust filter 7 will be continuously scraped off by the soft brushes 9. The fallen dust falls into the collection box 13 below under the action of gravity and is collected. The air filtered by the dust filter 7 flows into the upper part along the exhaust pipe 10 and is discharged under the action of the fan 11;

[0052] When it is necessary to clean the collection box 13 in one of the dust removal boxes 2, the operator turns the knob 5, which drives the reversing plate 4 to rotate during the rotation. The operator rotates the reversing plate 4 to the side of the dust removal box 2 that needs to be cleaned until a "click" sound is heard. At this time, the reversing plate 4 is re-constrained and limited by the limiting component on the corresponding side. At this time, the gas containing dust in the air inlet end of the air inlet pipe 1 cannot enter the air outlet end on the side blocked by the reversing plate 4, and can only enter the dust removal box 2 on the other side from the air outlet end on the other side. At this time, the operator will need to clean one side The collecting box 13 is pulled out from the dust removal box 2, and the dust in the collecting box 13 is cleaned. After cleaning, the collecting box 13 is reinserted into the discharge port of the dust removal box 2 on that side. Then the operator can clean the dust in the collecting box 13 in the dust removal box 2 on the other side according to the above principle. It is worth adding that when the dust in the collecting boxes 13 in the dust removal boxes 2 on both sides is cleaned, in order to ensure the dust removal efficiency of the device, the operator needs to reset the knob 5, that is, to ensure that the reversing plate 4 is in the center position and will not block the dust and gas from entering the dust removal boxes 2 on both sides at the same time.

[0053] By setting two dust removal boxes 2, and by setting a knob 5, a reversing plate 4 and an air inlet pipe 1, the reversing plate 4 is used to change the direction of the air duct in the inner cavity of the air inlet pipe 1, so as to change the direction of the dust gas, so that when the operator cleans the dust in the collection box 13 in one of the dust removal boxes 2, the dust removal box 2 on the other side can also maintain normal operation, thereby ensuring the continuous operation of the PVC glove production. At the same time, by setting two dust removal boxes 2 and using two dust removal filters 7 to shunt and filter the gas in the air inlet pipe 1, the filtering effect of the device is improved; further, a filter box 12 is set above the fan 11, and activated carbon is used to perform secondary filtration on the filtered gas to remove harmful impurities and odors that may be contained in the first filtered gas, thereby greatly improving the overall filtering effect of the device.

[0054] Embodiment 2:

[0055] This embodiment provides a dust removal device for PVC glove production equipment, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the driving component includes:

[0056] The worm wheel 14 is sleeved and fixed on the circumferential wall of the exhaust duct 10 and is located in the insulating layer of the dust removal box 2. A worm 15 is meshed on the circumferential side of the worm wheel 14, and one end of the worm 15 is fixed with a bearing seat 16 fixed to the inner wall of the dust removal box 2. A motor 17 is fixedly installed on the outer wall of the dust removal box 2, and the output shaft end of the motor 17 passes through the outer wall of the dust removal box 2 and extends to the insulating layer of the dust removal box 2 and is coaxially connected to the worm 15.

[0057] Among them, when it is necessary to clean the dust on the circumferential wall of the dust filter 7, start the motor 17, the output shaft of the motor 17 drives the worm 15 to rotate, the worm 15 drives the worm wheel 14 to rotate, and the exhaust duct 10 fixed to the worm wheel 14 rotates accordingly, and the exhaust duct 10 drives the dust filter 7 to rotate synchronously. The dust accumulated on the surface wall of the dust filter 7 is continuously scraped off by the soft brushes 9 on both sides, and falls into the collection box 13 below under the action of gravity. It is worth adding that the exhaust duct 10 is rotatably connected to the dust removal box 2 and the partition 6.

[0058] By setting up a driving component, using a motor 17 for driving, and transmitting through a worm 15 and a worm gear 14, the exhaust duct 10 and the dust filter 7 can rotate, thereby cooperating with the soft brushes 9 on both sides of the dust filter 7 to remove dust accumulated on the surface of the dust filter 7.

[0059] Embodiment 3:

[0060] This embodiment provides a dust removal device for PVC glove production equipment. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the soft brush 9 is in contact with the circumferential wall of the dust removal filter 7.

[0061] During the rotation of the dust filter 7, different positions of the circumferential wall of the dust filter 7 can fully contact the soft brushes 9 on both sides.

[0062] Ensure that the soft brushes 9 on both sides can remove the dust accumulated on the surface of the dust removal filter 7.

[0063] Embodiment 4:

[0064] This embodiment provides a dust removal device for PVC glove production equipment, which, in addition to the technical solutions of the above embodiments, also has the following technical features. The limiter assembly includes:

[0065] A limit block 18 is fixedly installed on the upper surface of the air inlet duct 1. A slide groove 19 is provided in the limit block 18. A plug 20 is slidably connected in the slide groove 19. A spring 21 is provided just above the plug 20 and in the slide groove 19. Both ends of the spring 21 are respectively fixed to the inner top surface of the slide groove 19 and the upper surface of the plug 20. The bottom of the plug 20 is hemispherical. A hemispherical groove 22 is provided on the upper surface of the reversing plate 4 to accommodate the bottom end of the plug 20 to slide into. The plug 20 is plugged into the hemispherical groove 22, and the three limit blocks 18 are distributed in a fan shape.

[0066] Among them, when the operator rotates the reversing plate 4 through the knob 5, the reversing plate 4 is subjected to force and rotates to one side. At this time, the plug 20 in the previous limit assembly slides out of the hemispherical groove 22. When the reversing plate 4 rotates to the bottom of another limit assembly, the upper surface of the reversing plate 4 will first squeeze the plug 20 in the limit assembly, so that the plug 20 slides into the corresponding slide groove 19 and squeezes the spring 21 directly above it. As the plug 20 slides into the hemispherical groove 22, under the action of the spring 21, the bottom end of the plug 20 will quickly bounce into the inner cavity of the hemispherical groove 22. At this time, the operator can hear a "click" sound, which means that the reversing plate 4 is constrained by the new limit assembly. In the absence of external force, the reversing plate 4 will not rotate arbitrarily under the action of the limit assembly.

[0067] By providing a limit assembly and utilizing the cooperation between the plug 20 and the hemispherical groove 22 , the reversing plate 4 will not rotate randomly when no external force is applied.

[0070] The gas filtered once may be filtered twice through the filter box 12 .

[0071] Activated carbon is used to perform secondary filtration on the filtered gas to remove harmful impurities and odors that may be contained in the first filtered gas, greatly improving the overall filtering effect of the device.

[0072] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
