Description

Technical Field

[0001] The invention relates to the field of laundry beads production equipment, in particular to a pulse dust removal equipment for laundry beads production. Background Art

[0002] Laundry detergent beads are composed of a water-soluble outer membrane that can withstand heavy pressure and concentrated detergent. When used in a washing machine to wash clothes, they dissolve in water and can quickly dissolve the concentrated detergent into water, assisting the washing machine in cleaning clothes.

[0003] A pulse dust collector is one that removes dust attached to the filter medium by blowing compressed air. It is controlled by a pulse controller or PLC. Each time a group of pulse valves is opened, dust is removed from the bag or filter cartridge it controls, while other bags or filter cartridges work normally. After a period of time, the next group of pulse valves is opened to clean the next part. The dust collector consists of a hopper, an upper box, a middle box, a lower box and other parts. The upper, middle and lower boxes are chamber structures.

[0004] In order to ensure product quality, existing laundry detergent beads production workshops generally choose to produce laundry detergent beads in clean workshops. The dust removal method in the laundry detergent beads production process is to purify the air in the production workshop to reduce the dust content in the production workshop to achieve the purpose of improving product quality.

[0005] With regard to the above-mentioned related technologies, the construction cost of existing clean workshops is relatively high, and a large number of dust removal equipment are required to continuously purify the air in the production workshop to maintain a high air quality, which in turn leads to an increase in the cost of producing laundry beads. In summary, the use cost of existing dust removal equipment used in the production of laundry beads is relatively high. Summary of the invention

[0006] Based on this, the purpose of the present invention is to provide a pulse dust removal device for the production of laundry beads to solve the technical problem of high use cost of the existing dust removal equipment used in the production of laundry beads.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a pulse dust removal device for the production of laundry beads, comprising a pulse dust removal box, an air suction box is provided at the air inlet end of the pulse dust removal box, and an air outlet end is connected to an exhaust pipe, the air suction box is connected to the exhaust pipe, and also comprises an outer shell, an inner shell is connected to the outer shell, and a windshield cotton is fixedly connected to the bottom edge of the outer shell, the windshield cotton is closely attached to the surface of the mold drum used for the production of laundry beads, and the width is greater than the width of the liquid injection groove on a single mold drum, the exhaust pipe is connected to the interior of the outer shell, and the air suction pipe is connected to the interior of the inner shell.

[0008] By adopting the above technical solution, the airflow generated by the air flow is used to remove the dust adhered to the surface of the mold drum, while preventing the dust-containing air from the outside from entering the double-layer shell. The mold drum that is about to be filled with liquid is efficiently dusted. Under the premise of maintaining the production quality of laundry beads, the cost of air purification in the production workshop due to the deployment of a large number of air purification equipment is effectively reduced.

[0009] The present invention is further configured such that the inner shell is rotatably connected to the outer shell, the width of the inner shell is also greater than the width of a single injection groove, and cleaning mechanisms are provided on both sides of the inner shell for cleaning dust on the surface of the mold roller into the inner shell.

[0010] By adopting the above technical solution, when the mold drum is rotating, since the inner shell is connected to the inner wall of the outer shell through the rotating shaft, the inside of the inner shell is in a negative pressure state, while the outer shell and the inner shell are in a positive pressure state. When the side of the inner shell is aligned with the injection groove, it is pressed down by the air pressure, and similarly, the other side is tilted, so that the inner shell makes a circular swing with the rotating shaft connected to the outer shell, thereby increasing the gas flow rate flowing through the injection groove into the inner shell, and improving the dust collection effect in the injection groove.

[0011] The present invention is further configured such that the air extraction pipe is located inside the outer shell, and a flexible air connection pipe is provided at a position connected to the inner shell.

[0012] By adopting the above technical solution, it is avoided that the exhaust pipe is rigidly connected to the inner shell and interferes with the movement of the inner shell.

[0013] The present invention is further configured such that, when the mold roller rotates, the side of the inner shell that is first close to the injection groove is the leading side, and the other side is the trailing side, a plurality of first rollers are arranged on the surface of the inner shell facing the mold roller, and a first cleaning roller is rotatably connected to the leading side, and the rotating shaft of the first cleaning roller is connected to the rotating shaft of the first roller through a transmission belt.

[0014] By adopting the above technical solution, when the mold roller rotates, the first roller continuously contacts with the outer wall of the mold roller and generates relative rotation. The first cleaning roller driven by the first roller on the front side of the inner shell sweeps the dust on the outer wall of the mold roller, and sweeps the dust on the outer wall of the mold roller into the inner shell, thereby achieving a better dust collection effect on the surface of the mold roller under the action of the negative pressure inside the inner shell.

[0015] The present invention is further configured such that the rear side of the inner shell is rotatably connected to a second cleaning roller, the second cleaning roller is coaxially fixedly connected to at least one second roller, the second roller can contact the surface of the mold roller, and the inner shell is provided with a torsional energy storage assembly at the rotating shaft of the second cleaning roller.

[0016] By adopting the above technical solution, the energy storage component releases energy to make the second cleaning roller rotate at high speed in the same direction relative to the mold roller. Since the second cleaning roller is located on the tail side of the inner shell, the second cleaning roller rotating at high speed and in contact with the outer wall of the mold roller can sweep the dust on the surface of the mold roller to the inside of the inner shell, thereby further improving the dust collection effect on the surface of the mold roller.

[0017] The present invention is further configured such that a first roller is connected to the inner shell via a spring telescopic column, and the first roller is always in close contact with the surface of the mold roller.

[0018] By adopting the above technical solution, the first roller is prevented from losing contact with the mold cylinder.

[0019] The present invention is further configured such that when the front side of the inner shell contacts the mold roller, the second roller is out of contact with the mold roller, and the second cleaning roller keeps contacting the surface of the mold roller.

[0020] By adopting the above technical solution, when the rear side of the inner shell is tilted, the potential energy stored in the energy storage box is released to drive the second cleaning roller to rotate at a high speed to sweep the dust on the surface of the mold roller into the inner shell.

[0021] The present invention is further configured such that when the rear side of the inner shell contacts the mold roller, the first cleaning roller keeps contacting the surface of the mold roller.

[0022] By adopting the above technical solution, during the process of the energy storage box rotating and storing energy, the first cleaning roller keeps rotating under the drive of the first roller. At this time, the front side of the inner shell is in a raised state, and the air between the inner shell and the outer shell enters the inner shell through the gap between the front side of the inner shell and the mold roller. Along with the sweeping of the first cleaning roller, the dust on the surface of the mold roller and in the injection groove is brought into the inner shell.

[0023] The present invention is further configured such that both ends of the shell are provided with mounting components for connecting to a laundry beads production device, and the shell is installed on a surface of a mold drum of the laundry beads production device near a detergent spray port.

[0024] By adopting the above technical scheme, before the washing liquid contact port of the laundry beads production equipment sprays washing liquid into the liquid injection groove, the dust removal device is used to remove dust from the liquid injection groove and the surface of the mold drum. This can not only avoid excessive impurities in the laundry beads, but also improve the sealing quality between adjacent laundry beads, thereby avoiding the situation where the laundry beads are pressurized and leak.

[0025] In summary, the present invention mainly has the following beneficial effects:

[0026] 1. The present invention sets a double-layer shell structure by fitting the mold drum of the laundry condensation bead production equipment, and uses two pipes to connect the corresponding inner and outer shells respectively, so that the two pipes are respectively connected to the air inlet end and the air outlet end of the pulse dust removal box, and an exhaust fan is arranged at the air inlet end of the pulse dust collector to continuously circulate the air in the double-layer shell, and the airflow generated by the air flow is used to take away the dust adhered to the surface of the mold drum, while preventing the dust-containing air from the outside from entering the double-layer shell, and efficiently removes dust from the mold drum that is about to be filled with liquid. On the premise of maintaining the production quality of the laundry condensation beads, the cost of air purification in the production workshop due to the deployment of a large number of air purification equipment is effectively reduced;

[0027] 2. The present invention rotatably connects the inner shell to the outer shell, and rotatably arranges cleaning roller structures for cleaning the surface of the mold roller on both sides of the inner shell. The inner shell is intermittently rotated relative to the outer shell by utilizing the pressure difference generated by the intermittent alignment of the negative pressure environment in the inner shell with the injection grooves on the mold roller moving at a uniform speed. When the inner shell intermittently lifts the sides on both sides, the two groups of cleaning rollers are driven by the driving structure to rotate and sweep the dust on the surface of the mold roller to the inside of the inner shell, thereby further improving the dust collection capacity.

[0028] 3. The present invention installs a first roller that is always in contact with the mold roller in the inner shell, and uses the rotating shaft of the first roller to cooperate with the transmission structure to drive one of the cleaning rollers. When the edge of the inner shell is lifted on one side of the cleaning roller, the cleaning roller rotates to sweep the dust adhered to the surface of the mold roller into the inner shell, thereby effectively cleaning the dust adhered to the surface of the mold roller;

[0029] 4. The present invention rotatably connects another cleaning roller to one side of the inner shell, and arranges a torsional energy storage assembly at the rotating shaft of the cleaning roller. When the edge of the inner shell is lowered on one side of the cleaning roller, the second roller fixedly connected to the cleaning roller shaft contacts the surface of the mold roller to make the cleaning roller slowly rotate in the opposite direction. At this time, the torsional energy storage assembly stores energy. When the side of the inner shell corresponding to the cleaning roller is lifted, the second roller is out of contact with the mold roller. The torsional energy storage assembly releases energy to drive the cleaning roller to rotate rapidly, sweeping the dust adhered to the surface of the mold roller into the inner shell, thereby further improving the dust cleaning effect on the surface of the mold roller.

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] The following describes an embodiment of the present invention based on its overall structure.

[0044] Embodiment 1

[0045] A pulse dust removal device for producing laundry beads, such as Figure 1-11As shown, it includes a pulse dust removal box 1. Specifically, the pulse dust removal box 1 is a pulse dust collector, which can effectively separate dust in the gas. The air inlet end of the pulse dust removal box 1 is provided with an exhaust box 3, and the air outlet end is connected to an exhaust pipe 7, and the exhaust box 3 is connected to an exhaust pipe 6. Specifically, the air outlet end of the pulse dust removal box 1 is connected to the exhaust pipe 7 through an air outlet pipe 5, which is used to discharge the purified clean air, and the exhaust box 3 is connected to the exhaust pipe 6 through an air inlet pipe 4, which is used to extract the dust-containing air in the inner shell 8.

[0046] It also includes an outer shell 2, which is connected to an inner shell 8. A windshield cotton 202 is fixedly connected to the bottom edge of the outer shell 2. The windshield cotton 202 is close to the surface of the mold roller 14 used for the production of laundry beads, and its width is greater than the width of the liquid injection groove 1401 on a single mold roller 14. Specifically, the outside air cannot directly pass through the liquid injection groove 1401 and enter the inside of the outer shell 2, so that the dust-containing air from the outside will not enter the inside of the outer shell 2 along the airflow when the inside of the inner shell 8 is under negative pressure. The outer shell 2 and the inner shell 8 cooperate with the pulse dust removal box 1 to realize internal air circulation, thereby improving the dust removal quality of the mold roller 14. The exhaust pipe 7 is connected to the inside of the outer shell 2, and the exhaust pipe 6 is connected to the inside of the inner shell 8.

[0047] See also Figure 1-4 Both ends of the shell 2 are provided with mounting components for connecting to the laundry beads production equipment. Specifically, both ends of the shell 2 are fixedly connected with mounting ears 203. The shell 2 is installed on the surface of the mold drum 14 of the laundry beads production equipment near the detergent liquid nozzle. Before the detergent liquid nozzle of the laundry beads production equipment sprays the detergent into the liquid injection groove 1401, the dust removal device is used to remove dust from the liquid injection groove 1401 and the surface of the mold drum 14, which can not only avoid the impurities in the laundry beads from exceeding the standard, but also improve the sealing quality between adjacent laundry beads, and avoid the laundry beads from leaking due to pressure.

[0048] See also Figure 3-6The inner shell 8 is rotatably connected to the outer shell 2. Specifically, a connecting frame 201 is fixedly installed in the outer shell 2. The bottom end of the connecting frame 201 is rotatably connected to the outer shell 2. The width of the inner shell 8 is also greater than the width of a single injection groove 1401. The inner shell 8 is close to but does not contact the outer wall of the mold roller 14, so that the inner shell 8 can fully absorb the dust in the injection groove 1401 and prevent the inner shell 8 from rotating at a large angle. Both sides of the inner shell 8 are provided with a cleaning device for cleaning the dust on the surface of the mold roller 14 into the inner shell 8. The cleaning mechanism, when the mold roller 14 is rotating, since the inner shell 8 is connected to the inner wall of the outer shell 2 through the rotating shaft, the interior of the inner shell 8 is in a negative pressure state, while the outer shell 2 and the inner shell 8 are in a positive pressure state. When the side of the inner shell 8 is aligned with the injection groove 1401, it is pressed down by the air pressure, and similarly, the other side is tilted, so that the inner shell 8 makes a circular swing with the rotating shaft connected to the outer shell 2, increasing the gas flow rate flowing through the injection groove 1401 into the inner shell 8, and improving the dust collection effect in the injection groove 1401.

[0049] Embodiment 2

[0050] A pulse dust removal device for producing laundry beads, such as Figure 1-11 As shown, on the basis of Example 1, the difference from Example 1 lies in that, when the mold roller 14 rotates, the side of the inner shell 8 that is first close to the injection groove 1401 is the leading side, and the other side is the trailing side, a plurality of first rollers 801 are arranged on the surface of the inner shell 8 facing the mold roller 14, and a first cleaning roller 9 is rotatably connected to the leading side, and the rotating shaft of the first cleaning roller 9 is connected to the rotating shaft of the first roller 801 through a transmission belt 11.

[0051] Specifically, the rotation direction of the first roller 801 is opposite to that of the mold roller 14. Similarly, the rotation direction of the first cleaning roller 9 is also opposite to that of the mold roller 14. When the mold roller 14 rotates, the first roller 801 continuously contacts the outer wall of the mold roller 14 and generates relative rotation. The first cleaning roller 9 driven by the first roller 801 on the front side of the inner shell 8 sweeps the dust on the outer wall of the mold roller 14 and sweeps the dust on the outer wall of the mold roller 14 into the inner shell 8, thereby achieving a better dust collection effect on the surface of the mold roller 14 under the action of the negative pressure inside the inner shell 8.

[0052] See also Figure 3-6The rear side of the inner shell 8 is rotatably connected to a second cleaning roller 10, and the second cleaning roller 10 is coaxially fixedly connected to at least one second roller 12, and the second roller 12 can contact the surface of the mold cylinder 14. The inner shell 8 is provided with a torsion energy storage component at the rotating shaft of the second cleaning roller 10. Specifically, the torsion energy storage component is an energy storage box 13, and a clockwork spring is arranged in the energy storage box 13. During the reverse rotation of the second cleaning roller 10 and the mold cylinder 14, the clockwork spring in the energy storage box 13 stores elastic potential energy, and when the second roller 12 is out of contact with the mold cylinder 14, the elastic potential energy of the clockwork spring in the energy storage box 13 is released, thereby driving the second cleaning roller 10 to rotate quickly in the same direction as the mold cylinder 14, and sweeping the dust on the surface of the mold cylinder 14 into the inner shell 8.

[0053] In this embodiment, preferably, the first cleaning roller 9 and the second cleaning roller 10 are both brush rollers. When the brushes contact the surface of the mold roller 14, the air between the outer shell 2 and the inner shell 8 can enter the inner shell 8 through the gap between the brushes. Further, with the rotation of the first cleaning roller 9 or the second cleaning roller 10, the dust can be better swept into the inner shell 8.

[0054] Specifically, the second cleaning roller 10 keeps relative rotation with the mold roller 14 when the second roller 12 contacts the outer wall of the mold roller 14, and the rotation directions of the two are opposite. At this time, since the rear side of the inner shell 8 is close to the mold roller 14, the second cleaning roller 10 is compressed and deformed, and it is not easy to sweep the dust away from the inner shell 8. When the rear side of the inner shell 8 is tilted and the second roller 12 is out of contact with the outer wall of the mold roller 14, the energy storage component releases energy to make the second cleaning roller 10 rotate at a high speed in the same direction as the mold roller 14. Since the second cleaning roller 10 is located on the rear side of the inner shell 8, the second cleaning roller 10 that rotates at a high speed and contacts the outer wall of the mold roller 14 can sweep the dust on the surface of the mold roller 14 to the inside of the inner shell 8, thereby further improving the dust collection effect on the surface of the mold roller 14.

[0055] See also Figure 3-11 When the front side of the inner shell 8 contacts the mold roller 14, the second roller 12 breaks away from contact with the mold roller 14, and the second cleaning roller 10 keeps contacting the surface of the mold roller 14. When the rear side of the inner shell 8 is tilted, the potential energy accumulated in the energy storage box 13 is released to drive the second cleaning roller 10 to rotate at a high speed to sweep the dust on the surface of the mold roller 14 into the inner shell 8. When the rear side of the inner shell 8 contacts the mold roller 14, the first cleaning roller 9 keeps contacting the surface of the mold roller 14. During the process of the energy storage box 13 rotating and storing energy, the first cleaning roller 9 keeps rotating under the drive of the first roller 801. At this time, the front side of the inner shell 8 is in a tilted state, and the air between the inner shell 8 and the outer shell 2 enters the inner shell 8 through the gap between the front side of the inner shell 8 and the mold roller 14. Along with the sweeping of the first cleaning roller 9, the dust on the surface of the mold roller 14 and in the injection groove 1401 is brought into the inner shell 8.

[0056] See also Figure 2-9 The exhaust pipe 6 is located in the outer shell 2, and a flexible air connecting pipe 601 is provided at the connection with the inner shell 8. Specifically, the flexible air connecting pipe 601 can be a bellows. Under the premise of maintaining the negative pressure in the pipe, it can bend and deform at a certain angle to provide good movement conditions for the inner shell 8, avoid the exhaust pipe 6 and the inner shell 8 being rigidly connected and interfering with the movement of the inner shell 8, and a first roller 801 is connected to the inner shell 8 through a spring telescopic column. The first roller 801 is always in close contact with the surface of the mold roller 14 to avoid the first roller 801 being out of contact with the mold roller 14.

[0057] The working principle of the present invention is as follows: the vacuum box 3 works to maintain a negative pressure in the vacuum pipe 6, and the air between the outer shell 2 and the inner shell 8 enters the inner shell 8 through the gaps on both sides of the inner shell 8, and then enters the pulse dust removal box 1 along the negative pressure pipeline. After the dust is filtered by the pulse dust removal box 1, the clean air enters the exhaust pipe 7 along the air outlet pipe 5, and then returns to between the outer shell 2 and the inner shell 8. In this way, during the circulation of the mold drum 14, the dust on the surface of the mold drum 14 and in the injection groove 1401 is continuously adsorbed and collected, so that the injection groove 1401 to be filled with detergent is in a clean and dust-free state, thereby maintaining the production quality of the laundry beads at a lower cost, and completing the dust removal process in the production process of the laundry beads.

[0058] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
