Description

Technical field:

[0002] The invention relates to the technical field of textile product production equipment, and more specifically to a down-sweeping and down-absorbing device with a double air outlet structure. Background technology:

[0004] In the production process of down clothing, home textile products such as mattresses, pillows, and plush toys, there is a process of filling down or cotton. After filling down or cotton, it is necessary to beat it to make the filling uniform. The existing beating methods include manual beating and simple machine beating. However, beating easily causes dust and floating of down and cotton, which not only pollutes the production environment, but also has a certain impact on the health of workers.

[0005] Chinese utility model CN201921317395.2 provides a dust suction device for an automatic down and cotton beating machine, comprising a down and cotton beating machine body, a dust suction pipe and a suction fan; the dust suction pipe is respectively arranged on the outside of the down filling piece inlet and the down filling piece outlet of the down and cotton beating machine body, and the two ends of the dust suction pipe are respectively connected and fixed to the down and cotton beating machine body, and the surface of the dust suction pipe is provided with a dust suction port arranged toward the down filling piece inlet and the down filling piece outlet; the suction fan is installed and fixed on the equipment bracket of the down and cotton beating machine body, and the air inlet of the suction fan is connected to the dust suction pipe. Although the above-mentioned automatic down and cotton beating machine dust suction device solves the problem of suctioning down and dust to a certain extent, it still has many shortcomings; for example, the filtering device connected to the outer side of the air outlet of the suction fan is a dust bag, but the down and cotton wool raised by beating are relatively small. If a dust bag is used for collection, the dust bag is easily filled with air under the action of the suction fan, and the down or cotton wool collected in the dust bag will adhere to the inner surface of the dust bag, thereby increasing the filtration resistance and having to be disassembled and replaced. However, in fact, the dust bag only contains a small amount of down, and its utilization rate is low. The negative effects brought about by this include but are not limited to: the dust bag needs to be frequently disassembled and replaced during the down collection process, which is not only costly but also time-consuming and labor-intensive. Summary of the invention:

[0007] The purpose of the present invention is to provide a down-sweeping and down-absorbing device with a double air outlet structure in view of the shortcomings of the prior art, so as to at least solve one of the technical problems existing in the prior art; the down-sweeping and down-absorbing device can not only realize down-sweeping and down-absorbing, but also has a large down-absorbing capacity at a single time and a long replacement cycle, and there is no need to frequently replace collection devices such as collection boxes or collection bags.

[0008] The technical solutions of the present invention are as follows:

[0014] Preferably, the air suction port comprises a first air suction port located below the conveyor belt and a second air suction port located above the conveyor belt.

[0015] Preferably, a duct outlet cleaning portion is provided at one end of the first duct close to the gathering portion, and the duct outlet cleaning portion is a passage with a reduced diameter relative to the pipelines adjacent to both ends thereof, and at least part of the duct outlet is arranged on the duct outlet cleaning portion.

[0016] Preferably, the cleaning device is provided with an annular scraper, and the outer ring of the annular scraper is made of elastic material.

[0017] Preferably, a detachable connection structure is provided between the first conduit and the material collecting portion, and between the second conduit and the material collecting portion.

[0018] Preferably, the first conduit and the second conduit are connected to the cover plate, and communicate with the material collecting part through the through hole of the cover plate. The cover plate is detachably mounted on the opening of the material collecting part, and a slider device for controlling the cover plate to slide up and down is connected to the cover plate.

[0019] The beneficial effects of the present invention are:

[0020] The present invention includes the duct air outlet and the collection part air outlet, which are combined to form a double air outlet structure; when collected materials such as down or cotton wool accumulate on the inner wall of the collection part and block the air outlet of the collection part, a smooth directional air duct from the air suction port to the collection part can still be formed through the duct air outlet to collect down and cotton wool to fill the storage space in the middle of the collection part. At the same time, a cleaning device is installed at the duct air outlet, and the collected materials attached to the inner wall of the duct air outlet can be pushed into the collection part through the cleaning device, so that the air duct from the air suction port to the collection part is more stable, and it can also ensure that the collection part can be effectively filled with collected materials before replacement, thereby increasing the single collection capacity of the collection part, extending the replacement cycle, reducing the waste of production time, and improving the overall production efficiency.

[0021] The present invention includes an air volume sensor arranged in the first duct for sensing the air volume. By detecting the air volume in the first duct, the blockage conditions of the duct air outlet and the gathering part air outlet can be reflected in real time and effectively. Combined with the cleaning device, when the air outlet is detected to be blocked, it can be automatically cleaned immediately to improve the overall down suction efficiency of the device.

[0022] The present invention includes a destaticizing device, through which materials entering the down-beating device body can be destaticized, effectively avoiding static adsorption of collected objects such as down or cotton wool, while optimizing the beating and improving the down absorption effect of the device.

[0023] The present invention includes a conveyor belt with mesh holes, and a funnel connected to a material collecting part is provided below the conveyor belt to collect attachments such as down or cotton wool on the bottom surface of the beaten material, thereby improving the overall down absorption effect of the device, rather than simply performing down absorption treatment on the top surface or side surface of the beaten material.

[0024] The present invention includes a venturi-like structure formed by the duct air outlet cleaning part and the pipelines adjacent to both ends thereof, ensuring that when the air outlet of the collecting part is unobstructed, the duct air outlet will not be completely blocked before the air outlet of the collecting part, so that the collected materials can be better collected in the collecting part, thereby improving the overall lint absorption and collection effect of the device.

[0025] The present invention includes an annular scraper whose outer ring is made of elastic material, which can effectively prevent the cleaning device from damaging the duct air outlet during the process of cleaning the blockage of the duct air outlet. Moreover, when the outer ring of the annular scraper has a certain elasticity, it can make the contact with the inner wall of the duct air outlet closer and the cleaning effect is better.

[0026] The present invention comprises a cover plate detachably mounted on the opening of the material collecting part, the cover plate is connected with a slider device, and the slider device can drive the cover plate to move up and down to complete the opening and closing control of the material collecting part, so as to facilitate the replacement of the material collecting part.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0044] A down-sweeping and down-sucking device with a double air outlet structure, see attached Figure 1 To Attachment Figure 6 , including a down-beating device body 1, the down-beating device body 1 is provided with at least one air suction port, the air suction port is connected to the collection part 12 through a first duct 4, and at least one fan assembly is provided to form a directional air duct from the air suction port to the collection part 12; the first duct 4 is provided with a duct outlet 4011 at one end close to the collection part 12; the first duct 4 is provided with a cleaning device 8 for cleaning the inner wall attachments of the duct outlet 4011; the collection part 12 is provided with at least one collection part outlet 1201. Preferably, the air outlet structure of the duct outlet 4011 and the collection part outlet 1201 is adapted to the size of the collected down or cotton wool, and can be a mesh structure, a uniformly arranged fine through-hole structure, etc.

[0045] Preferably, due to the directional air duct formed by the fan assembly from the air suction port to the collection portion 12, dust, down, cotton wool and other easily floating objects raised by the flapping of the flapping device 2 inside the down-beating device body 1 will follow the air duct from the air suction port along the first duct 4 into the collection portion 12; in this process, the down, cotton wool and other easily floating objects will pass through the duct air outlet 4011, and since down, cotton wool and other easily floating objects are easily adsorbed on the air outlet, both the duct air outlet 4011 and the collection portion air outlet 1201 will be accumulated and blocked due to the adsorption of down, cotton wool and other easily floating objects, making it impossible for the duct air outlet 4011 and the collection portion 12 to exhaust air, thereby hindering the formation of the directional air duct. The cleaning device 8 can clean the down or cotton wool and other floating objects adsorbed on the duct air outlet 4011, and push the cleaned down or cotton wool and other floating objects into the collecting part 12 to restore the directional air duct, thereby ensuring the stability of the down absorption state. The collecting part 12 can be replaced after the full amount of collection is completed, the down absorption and collection amount is large, and the replacement cycle is long.

[0046] As an embodiment of the present invention, refer to the attached Figure 1 To Attachment Figure 5 The main body 1 of the velvet-beating device includes a conveyor belt 14 provided with mesh holes 1401 installed in the middle position of the main body 1 of the velvet-beating device, and the conveyor belt 14 crosses the main body 1 of the velvet-beating device; the conveyor belt 14 can be an integrated structure, and can also be assembled from modular components to ensure convenient disassembly and replacement, and can provide sufficient support; the modular components can be flat grid plate chains, mesh chains, combined mesh belts, etc., and the flat grid plate chains and mesh chains are both existing common sense structures, so they are not described in detail here; at least a part of the modular components are provided with mesh holes 1401. In the first embodiment, in order to achieve a better ventilation effect, a structure in which mesh holes 1401 are evenly distributed on the conveyor belt 14 is adopted; the size of the mesh holes 1401 is determined according to the size of the maximum surface attachment of the material to be beaten. The beating device body 1 also includes a beating device 2 arranged above the conveyor belt 14. The beating device 2 can be a single-beating rod beating or a multi-beating rod beating; it can be a vertical movement beating or a rotation beating; technical personnel in this field can make their own choices based on needs and existing technologies, so it will not be described in detail here and is not shown in the drawings.

[0047] Preferably, a destaticizing device 3 is provided at the feed inlet of the velvet-beating device body 1. The destaticizing device 3 may be at least one destaticizing ion rod or other structures for destaticizing. In the first embodiment, in order to optimize the destaticizing effect, a destaticizing device 3 may be installed at both the upper and lower ends of the feed inlet of the velvet-beating device body 1. When the material is fed through the feed inlet, the destaticizing device 3 may complete the destaticizing treatment of the inside of the material, the upper surface of the material and the lower surface of the material, so as to prepare for optimizing the beating, velvet suction and dust removal.

[0048] Preferably, in Example 1, in order to optimize the down suction effect, the suction port includes a first suction port 606 provided below the discharge port of the down-sweeping device body 1 and a second suction port 607 provided above the discharge port of the down-sweeping device body 1; one end of the first suction port 606 is connected to the second connecting pipe 605, and the other end is connected to the fourth connecting pipe 609; one end of the second suction port 607 is connected to the first connecting pipe 604, and the other end is connected to the third connecting pipe 608; the lower ends of the first connecting pipe 604, the second connecting pipe 605, the third connecting pipe 608, and the fourth connecting pipe 609 are all connected to the transfer pipe 6011, and the transfer pipe 6011 is connected to the second fan assembly 6010, and the air outlet end of the second fan assembly 6010 is connected to the second air outlet pipe 6012, and the second air outlet pipe 6012 is connected to the first duct 4, and the first duct 4 is provided with a duct outlet 4011 at one end close to the collection part 12. The fan assembly is a conventional fan structure, and its control method is also a common knowledge content, so it is not described in detail here, and it is not shown in the drawings. Further preferably, the second fan assembly 6010 can be installed between the air inlet and the first duct 4 according to the present invention, or it can be installed in the first duct 4, or it can be installed between the first duct 4 and the aggregate part 12, or it can be installed in other suitable locations where it can be installed. Those skilled in the art can make their own choices based on the content of the present invention.

[0049] Preferably, the movement of the cleaning device 8 can be controlled manually by directly observing the blocking state of the duct air outlet 4011; or the movement of the cleaning device 8 can be controlled by timing; or a sensor can be set to control the movement of the cleaning device 8. In order to make the operation simple and efficient, in the first embodiment, an air volume sensor for sensing the air volume is installed in the first duct 4. The air volume sensor can be installed at the end of the first duct 4 connected to the second air outlet pipe 6012 or the end connected to the collecting part 12, or installed in the middle of the first duct 4. When the air volume sensor detects that the air volume is weakened to a certain value, a feedback signal is given to the cleaning device 8, and the cleaning device 8 moves to clean the inner wall of the duct outlet 4011, and pushes the collected down or cotton wool adsorbed and blocked on the duct outlet 4011 into the collection part 12 to make the air duct from the suction port to the collection part 12 unblocked; through the air volume sensor, the duct outlet 4011 can be cleaned in real time according to the blockage state of the outlet to ensure the stability of the suction of down and improve the overall suction effect of the device. The air volume detection, signal feedback, and control of the air volume sensor are all common knowledge, and those skilled in the art can fully understand and reproduce them in combination with the content of the present invention, so they will not be described in detail here, and they are not shown in the drawings. Further, as a preferred embodiment, the specific data size of the certain value is based on comprehensive considerations such as the size of the equipment and the external pressure of the production environment. Those skilled in the art can set it by themselves in combination with the content of the present invention, and they will not be described in detail here.

[0050] Preferably, the shape and structure of the cleaning device 8 match the shape and structure of the first conduit 4 at the installation position of the cleaning device 8. In the first embodiment, in order to facilitate the installation and movement of the cleaning device 8, the end of the first conduit 4 connected to the collecting part 12 is a straight tube 401 of a straight cylinder type, and a mounting seat 803 for mounting the cleaning device 8 is provided on the straight tube 401; the cleaning device 8 includes a movable rod 801 that can slide up and down, the upper end of the cleaning device 8 is connected to the mounting seat 803, and the lower end is provided with an annular scraper 802 connected to the movable rod 801, the outer ring of the annular scraper 802 is annular, and the outer diameter of the annular scraper 802 is adapted to the inner diameter of the straight tube 401. Furthermore, the outer ring of the annular scraper 802 is made of elastic material, including but not limited to elastic materials such as rubber, silicone, elastic plastic, etc.; when the cleaning device 8 cleans the inner wall of the duct air outlet 4011, the outer ring of the annular scraper 802 will form an elastic extrusion with the inner wall of the duct air outlet 4011, so that the outer ring of the annular scraper 802 and the inner wall of the duct air outlet 4011 are closer, so as to achieve a better cleaning effect, and at the same time, damage to the annular scraper 802 or the duct air outlet 4011 can be avoided.

[0051] Preferably, the first conduit 4 and the second conduit 5 are connected to the cover plate 11, and are connected to the collection part 12 through the through hole 1101 of the cover plate 11. In the first embodiment, the aperture of the through hole 1101 is not less than the outer diameter of the annular scraper 802, so as to ensure that the annular scraper 802 can push the maximum amount of collected materials into the collection part 12. The cover plate 11 is detachably covered on the opening of the collection part 12. The collection part 12 can be a collection box structure or a collection bag structure, etc. The collection box structure is adopted in the first embodiment. Except for the opening surface connected to the cover plate 11, the other side surfaces or bottom surfaces of the collection part 12 can be provided with the collection part air outlet 1201. The more the collection part air outlet 1201, the better the air outlet effect and the better the down collection effect. Considering the cost and technology, the technicians in this field can choose the required setting position and number of the collection part air outlet 1201. Furthermore, in order to protect the material collection portion 12, a collecting box device 7 is also provided on the outside of the material collection portion 12, and at least one air outlet 701 is provided on the collecting box device 7; to facilitate the installation and positioning of the material collection portion 12, a limiting guide plate 13 is also provided on the collecting box device 7; to facilitate movement, rollers are provided at the bottom of the collecting box device 7, and the collecting box device 7 is provided with a material replacement port that can be opened and closed.

[0052] As the second embodiment of the present invention, based on the first embodiment, refer to the attached Figure 4 A funnel 603 is provided below the conveyor belt 14, the lower end of the funnel 603 is connected to the first fan assembly 602, the outlet end of the first fan assembly 602 is connected to the first outlet pipe 601, the first outlet pipe 601 is connected to the second conduit 5, the structure of the second conduit 5 and the connection between the second conduit 5 and the material collection part 12 refer to the first conduit 4 in the first embodiment. The collected down or cotton wool on the surface of the material connected with the conveyor belt 14 can pass through the mesh 1401 of the conveyor belt 14 along the air duct from the funnel 603, along the second conduit 5, and into the material collection part 12; the overall velvet absorption surface of the device is increased, and the overall velvet absorption effect of the device is improved.

[0053] As the third embodiment of the present invention, based on the first embodiment or the second embodiment, refer to the attached Figure 6, the first conduit 4 or the second conduit 5 is provided with a conduit outlet cleaning part 4012 at one end near the collecting part 12, and the conduit outlet cleaning part 4012 is a passage with a reduced diameter relative to the pipelines adjacent to both ends thereof, so as to form a local structure similar to a Venturi tube. The Venturi tube is a pipe that first contracts and then gradually expands. The Venturi effect will be generated through the Venturi tube. This effect is manifested in that when the restricted flow passes through the reduced flow section, the fluid has an increased flow velocity, and its flow velocity is inversely proportional to the flow section. According to Bernoulli's law, the increase in flow velocity is accompanied by a decrease in fluid pressure, which is the common Venturi phenomenon. In layman's terms, this effect refers to the low pressure generated near the high-speed flowing fluid, thereby generating an adsorption effect. In Example 3, the restricted flow passing through the reduced flow section refers to the flow section passing through the conduit outlet cleaning part 4012, and the conduit outlet cleaning part 4012 is connected to the cover plate 11 through the connecting port 4013. Furthermore, in the third embodiment, at least a portion of the duct air outlet 4011 is disposed on the duct air outlet cleaning portion 4012 ; and the outer diameter of the annular scraper 802 is adapted to the inner diameter of the duct air outlet cleaning portion 4012 .

[0054] Preferably, when the air outlet 1201 of the aggregate part has not been completely blocked, and the air outlet 4011 of the duct is basically completely blocked, a relatively low-pressure area will be formed in the cleaning part 4012 of the duct air outlet due to the change in flow rate, and the air pressure of the outside air and the air pressure of the gas in the cleaning part 4012 of the duct air outlet form a pressure difference, and the pressure difference makes the outside air have a driving force to flow into the cleaning part 4012 of the duct air outlet, and the driving force makes the outside air pass through the air outlet hole of the duct air outlet 4011 to the air attached to the duct air outlet. The collected objects on the inner wall of the outlet 4011 are pushed inward, so that at least part of the collected objects attached to the inner wall of the duct outlet 4011 can be separated from the duct outlet 4011 and flow into the collection part 12 along with the air duct in the duct; and when the duct outlet 4011 is unblocked to a certain extent, the duct outlet 4011 blows air outward, the low pressure area formed when blocked disappears, and the Venturi effect disappears accordingly, until the collected objects once again basically completely block the duct outlet 4011, the Venturi effect will appear again. This ensures that the duct outlet 4011 will not be completely blocked before the collection part outlet 1201, so that the collected objects can be better collected in the collection part 12. When the aggregate outlet 1201 on the inner side of the aggregate portion 12 is completely blocked, a relatively large and stable air duct cannot be formed. At this time, if the duct outlet 4011 is also blocked, the attachments on the inner wall of the duct outlet 4011 cannot be eliminated by the Venturi effect, and the duct outlet 4011 needs to be cleaned by the cleaning device 8.

[0055] As a further preference, based on the first embodiment, the second embodiment or the third embodiment, the cover plate 11 is connected with a slider device 10 for controlling the cover plate 11 to slide up and down, the slider device 10 is connected to the slider mounting frame 9, and the slider mounting frame 9 is connected to the collection box device 7. Furthermore, a door opening sensor is provided on the material exchange port of the collection box device 7. When the door opening sensor detects that the material exchange port is open, a signal can be fed back to the slider device 10 to control the slider device 10 to drive the cover plate 11 to leave the opening of the material collection part 12, and then the material collection part 12 can be replaced; by controlling whether the cover plate 11 is covered on the material collection part 12 by the door opening sensor and the slider device 10, the replacement efficiency can be improved, no manual disassembly is required, the replacement is convenient, and better installation accuracy can be guaranteed. The switch sensing, signal feedback, and motion control of the slider device 10 of the door opening sensor are all existing technologies of common knowledge, and those skilled in the art can fully understand them in combination with the content of the present invention, so they are not described in detail here, and are not shown in the drawings.

[0056] The specific usage is as follows:

[0057] When the material enters the down-beating device body 1 from the feed inlet, the anti-static device 3 will perform an overall anti-static treatment on the material. As the material further enters the down-beating device body 1, the beating device 2 will beat the material, and at the same time, the fan assembly 6 will absorb and collect the material. The collected materials such as down or cotton wool sucked by the fan assembly 6 will enter the collection part 12 through the first conduit 4 or the second conduit 5. When the air outlet 1201 of the collecting part 12 and the air outlet 4011 of the duct are blocked, the wind blown into the collecting part 12 by the fan assembly 6 cannot be discharged, so a high-pressure area will be formed in the collecting part 12, which will reduce the air volume in the first duct 4 and the second duct 5. When the air volume sensor detects that the air volume has decayed to a certain value, it will feedback a signal to control the movement of the annular scraper 802 of the cleaning device 8, thereby pushing the collected materials such as down or cotton wool attached to the inner wall of the duct air outlet 4011 into the collecting part 12, so that the duct air outlet 4011 is unblocked, and the fan assembly 6 can continue to collect and process the materials. When the collecting part 12 is full, the collecting part 12 can be replaced, or the collected materials such as down or cotton wool collected in the collecting part 12 can be processed and then reused.
