Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0030] Referring to "embodiments" herein means that the specific features, structures or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art understand explicitly and implicitly that the embodiments described herein can be combined with other embodiments.

[0031] In the process of fiberglass base fabric production, a cutting knife is used to cut both sides of the fiberglass base fabric neatly. The falling fiberglass yarn waste is cleaned by a vacuum cleaner. The currently used vacuum cleaner can suck the fiberglass yarn waste into the dust collection bin of the vacuum cleaner. After the dust collection bin of the vacuum cleaner is filled with fiberglass yarn waste, the operator needs to turn off the vacuum cleaner, open the door of the dust collection bin, and pour out the fiberglass yarn waste in the dust collection bin. This process is complex in operation, which will reduce the cleaning efficiency of the fiberglass yarn waste and increase the labor cost.

[0032] Based on this, the present invention provides a dust suction device, including a bin body, a bin door, a swinging mechanism and a driving part. Among them, a dust suction port communicating with the inner cavity of the bin body is arranged at the upper part of the bin body for fiberglass yarn waste to enter the bin body, and a dust discharge port communicating with the inner cavity of the bin body is arranged at the lower part of the bin body. The fiberglass yarn waste in the bin body can be discharged through the dust discharge port under the action of gravity. The bin door is used to open or close the dust discharge port. The swinging mechanism includes at least one swing arm. One end of the swing arm is rotatably connected to the bin body, and the other end of the swing arm is connected to the bin door to drive the bin door to move. The driving part is drivingly connected to the swing arm and is used to drive the swing arm to swing between a first position and a second position to drive the bin door to open or close the dust discharge port. Thus, the driving part can drive the bin door to move through the swing arm, automatically open the dust discharge port to timely discharge the waste in the bin body, and automatically close the dust discharge port to seal the bin body and ensure the dust suction effect.

[0033] An exemplary embodiment of the present invention provides a dust suction device. As Figure 1 shown, the dust suction device 1 includes a bin body 2, a bin door 3, a swinging mechanism 4 and a driving part 5. Among them, a dust suction port 22 communicating with the inner cavity of the bin body 2 is arranged at the upper part of the bin body 2 for sucking fiberglass yarn waste. A dust discharge port 21 communicating with the inner cavity of the bin body 2 is arranged at the lower part of the bin body 2 for discharging the fiberglass yarn waste collected in the inner cavity of the bin body 2 under the action of gravity. The bin door 3 cooperates with the dust discharge port 21 to open or close the dust discharge port 21. The swinging mechanism 4 includes at least one swing arm 41. One end of the swing arm 41 is rotatably connected to the bin body 2, and the other end of the swing arm 41 is connected to the bin door 3 for driving the bin door 3 to move. Exemplarily, two groups of swinging mechanisms 4 can be arranged. One group of swinging mechanisms 4 is arranged at one end of each bin door 3. Each group of swinging mechanisms 4 can include one swing arm 41, and the swing arm 41 is connected to the top surface of the bin door 3. In another embodiment, two groups of swinging mechanisms 4 are arranged, and one group of swinging mechanisms 4 is arranged at each end of the bin door 3. Each group of swinging mechanisms 4 includes two swing arms 41, and the swing arms 41 are connected to the top surface of the bin door 3. In this way, each group of swinging mechanisms 4 includes two swing arms 41. By the swinging of the two swing arms 41 to drive the bin door 3, the movement of the bin door 3 can be controlled more smoothly, and the situation of the bin door 3 tipping over during the movement can be avoided. The driving part 5 is drivingly connected to the swing arm 41, and the driving part 5 is used to drive the swing arm 41 to swing between a first position and a second position to drive the bin door 3 to open or close the dust discharge port 21.

[0034] In this embodiment, a plurality of dust suction ports 22 are provided on the dust suction device 1. The dust suction ports 22 can be located on the upper surface of the dust suction device 1 or on the side wall of the bin body 2. The shape of the dust suction port 22 is circular, and the shape of the dust suction port 22 can also be other shapes such as oval, rounded rectangle, rhombus, etc. As Figure 1 shown, exemplarily, the number of the dust suction ports 22 is 4. Among them, two dust suction ports 22 are located on the upper surface of the dust suction device 1, and the other two dust suction ports 22 are located on the side wall of the dust suction device 1. The dust suction port 22 is connected to the elbow 221 so that the dust suction port 22 is connected to a dust suction pipe (not shown in the figure) to suck in the fiberglass waste. Exemplarily, the dust suction port 22 and the elbow 221 are detachably connected, so that when the elbow 221 is damaged, it can be replaced in time, which is beneficial to reducing the maintenance cost. During the operation of the dust suction device 1, the operator can select the number of the dust suction ports 22 to be used according to the actual situation. Exemplarily, as Figure 2 shown, when the dust suction device 1 is operating, two dust suction ports 22 located on the upper surface of the bin body 2 suck in the fiberglass waste, and the other two dust suction ports 22 located on the side wall of the dust suction device 1 are closed.

[0035] In this embodiment, the dust discharge port 21 is provided at the lower part of the bin body 2. One or more dust discharge ports 21 can be provided, and the shape of the dust discharge port 21 can be oval, circular, square, etc. As Figure 1 shown, exemplarily, the dust suction device 1 is provided with one dust discharge port 21, and the shape of the dust discharge port 21 is rectangular.

[0036] In this embodiment, one end of the swing arm 41 is rotatably connected to the bin body 2, and the other end of the swing arm 41 is connected to the bin door 3 to realize the opening or closing of the bin door 3 driven by the swing arm 41. The swing arm 41 can be directly rotatably connected to the bin door 3, or the swing arm 41 can be rotatably connected to the bin door 3 through the connecting member 6. In one embodiment, the swing arm 41 is directly rotatably connected to the bin door 3 to ensure that during the movement of the bin door 3 driven by the swing arm 41, the bin door 3 always remains horizontal under the action of gravity, avoiding damage caused by collision with other structures during the movement of the bin door 3. In another embodiment, as Figure 1 shown, the swing arm 41 is connected to the bin door 3 through the connecting member 6. One end of the connecting member 6 is rotatably connected to the swing arm 41, and the other end of the connecting member 6 is fixedly connected to the bin door 3. Thus, during the process of opening or closing the dust discharge port 21, the bin door 3 can always remain horizontal, thereby avoiding the collision of the bin door 3.

[0037] Exemplarily, referring to Figure 1 , the first position is the position where the bin door 3 opens the dust discharge port 21. Referring to Figure 2, the second position is the position where the bin door 3 closes the dust exhaust port 21. In this way, when the driving part 5 drives the swing arm 41 to swing between the first position and the second position, the bin door 3 can be driven to open or close the dust exhaust port 21.

[0038] Reference Figure 1 and Figure 2 , in one embodiment, the swing arm 41 is configured such that when the swing arm 41 swings from the first position to the second position, the bin door 3 is driven by the swing arm 41. The bin door 3 receives a downward force and a force towards the outside of the bin body 2. Thus, the bin door 3 opens the dust exhaust port 21. In this way, it is ensured that when the bin door 3 is opened, it can open to both sides, completely opening the dust exhaust port 21, so that all the fiberglass waste in the bin body 2 falls down. When the swing arm 41 swings from the second position to the first position, the bin door 3 is driven by the swing arm 41. The bin door 3 receives an upward force and a force towards the inside of the bin body 2. Thus, the bin door 3 closes and seals the dust exhaust port 21. In this way, when the bin door 3 is closed, the sealing performance of the bin body 2 can be improved. The swing arm 41 drives the bin door 3 to swing between the first position and the second position to open and close the dust exhaust port 21, eliminating the need for an operator to disassemble the bin body 3 to pour out the fiberglass waste therein, which is beneficial to improving the cleaning efficiency and reducing the labor cost.

[0039] In one embodiment, the swing arm 41 includes a first arm portion 411 and a second arm portion 412 arranged at an angle. The angle between the first arm portion 411 and the second arm portion 412 can be set according to actual needs. Exemplarily, the angle between the first arm portion 411 and the second arm portion 412 is an obtuse angle. One end of the first arm portion 411 is rotatably connected to the bin body 2 to achieve the swing of the swing arm 41. The other end of the first arm portion 411 is connected to one end of the second arm portion 412, and the other end of the second arm portion 412 is connected to the bin door 3. The driving part 5 is drivingly connected to the intersection position of the first arm portion 411 and the second arm portion 412 to drive the swing of the swing arm 41, and further drive the bin door 3 connected to the swing arm 41 to open or close the dust exhaust port 21.

[0040] As Figures 1 to 3 shown, in this embodiment, the first arm portion 411 is connected to the bin body 2 through a swing arm support 413. Exemplarily, the swing arm support 413 can be a vertical structure made of stainless steel. One surface of the swing arm support 413 is detachably connected to the bin body 2, and a connection structure is provided on the other surface of the swing arm support 413 perpendicular to this surface. One end of the first arm portion 411 is rotatably connected to the swing arm support 413 through the connection structure. When the swing mechanism 4 moves, there is a space between the swing arm 41 and the bin body 2. Thus, it is possible to prevent the swing arm 41 from wearing the bin body 2 during the swing process, which is beneficial to extending the service life of the bin body 2.

[0041] In one embodiment, two sets of swing mechanisms 4 are provided. The two sets of swing mechanisms 4 are symmetrically arranged on both sides of the bin body 2, and each set of swing mechanisms 4 is connected to a bin door 3. As Figure 1 shown, the two sets of swing mechanisms 4 can respectively control the two bin doors 3 to open the dust discharge port 21. As Figure 2 shown, the two sets of swing mechanisms 4 can respectively control the two bin doors 3 to close the dust discharge port 21.

[0042] In this embodiment, as Figure 1 shown, when the two sets of swing mechanisms 4 move from the first position to the second position, the two sets of swing mechanisms 4 respectively drive the two bin doors 3 to move downward and in opposite directions at the same time. When both bin doors 3 reach the second position, the dust discharge port 21 is opened. Thus, the waste glass fiber yarn collected in the bin body 2 can fall under the action of gravity, and the bin body 2 can be emptied in time. As Figure 2 shown, when the two sets of swing mechanisms 4 move from the second position to the first position, the two sets of swing mechanisms 4 respectively drive the two bin doors 3 to move upward and relatively at the same time. When the two bin doors 3 reach the first position, the dust discharge port 21 is closed by the bin doors 3.

[0043] In one embodiment, a first sealing structure (not shown in the figure) is provided on the upper surface of the bin door 3, and a second sealing structure (not shown in the figure) is provided on the surface of the dust discharge port 21. When the bin door 3 moves from the second position to the first position, the first sealing structure and the second sealing structure can cooperate to close and seal the dust discharge port 21. In this way, when the dust discharge port 21 is closed, the sealing performance of the bin body 2 is increased, effectively preventing the waste glass fiber yarn collected in the bin body 2 from falling, and at the same time, preventing the bin body 2 from leaking air.

[0044] As Figure 3 shown, in one embodiment, the dust suction device 1 includes a frame body 7. The frame body 7 is used to provide support for the dust suction device 1, and the bin body 2 is fixed on the frame body 7. Thus, during the use of the bin body 2, the bin body 2 can be prevented from moving due to external forces. The driving part 5 includes a driving cylinder. The cylinder body 51 of the driving cylinder is rotatably connected to the frame body 7, and the piston rod 52 of the driving cylinder is rotatably connected to the swing arm 41.

[0045] As Figure 3 shown, in this embodiment, the frame body 7 is a rectangular parallelepiped frame, and the material of the frame can be, for example, stainless steel. Exemplarily, four support feet 71 are provided at the bottom of the frame body 7, and the four support feet 71 are fixedly connected to the bottom of the frame body 7. The support feet 71 can improve the structural stability of the frame body 7, reduce the influence of vibration on the dust suction device 1, and improve the structural stability of the dust suction device 1. The shape of the support feet 71 can be circular, or rectangular, oval, rhombic, hexagonal, etc., and this embodiment does not make any restrictions.

[0046] Refer to Figure 3 and Figure 4, In one embodiment, the shape of the bin body 2 is a funnel shape that is wider at the top and narrower at the bottom, with a trapezoidal cross-section. The bin body 2 includes four side walls. Among them, two opposite trapezoidal vertical side walls of the bin body 2 are arranged in parallel, with a trapezoidal shape that is wider at the top and narrower at the bottom; the other two opposite side walls of the bin body 2 are inclined, with a rectangular shape. In this embodiment, the frame body 7 includes a connection structure 75, and the connection structure 75 is connected to the two inclined side walls of the bin body 2 to provide support for the bin body 2. Exemplarily, the connection structure 75 is located at the middle and lower part of the inclined side wall, close to the driving part 5. The connection structure 75 is a rectangular frame. One long side of the rectangular frame is connected to the inclined side wall of the bin body 2, and the other long side is fixedly connected to the frame body 7. The two short sides of the rectangular frame are inclined, with one end of the short side fixedly connected to the inclined side wall of the bin body 2 and the other end fixedly connected to the frame body 7. In this way, the stability of the bin body 2 is effectively guaranteed. In this embodiment, the two side walls of the bin body 2 are inclined, so that the waste fiberglass yarn entering the bin body 2 can fall along the inclined side walls and gather at the bottom of the bin body 2. In this way, it is beneficial for the waste fiberglass yarn in the bin body 2 to gather downward and be discharged.

[0047] As Figure 4 shown, in this embodiment, a support structure is provided inside the bin body 2. The support structure includes a plurality of support rods 29. The support rods 29 are used to support the respective side walls of the bin body 2 to improve the structural stability of the bin body 2. Exemplarily, the support rods 29 can be arranged on one side of the inner cavity of the bin body 2. Three support rods 29 are arranged on each inclined side wall of the bin body 2, and the three support rods 29 are arranged in parallel at a preset interval; two support rods 29 are arranged on each trapezoidal vertical side wall of the bin body 2, and the two support rods 29 are arranged in parallel at a preset interval. The support rods 29 arranged on the inclined side walls of the bin body 2 have the same inclination angle as the side walls, are fixed on the inclined side walls, and are completely attached to the inclined side walls. The extending directions of the two support rods 29 arranged on the trapezoidal vertical side walls of the bin body 2 are the directions of the heights of the trapezoidal vertical side walls, and the two support rods 29 are fixed on the trapezoidal vertical side walls and are completely attached to the trapezoidal vertical side walls..

[0048] In one embodiment, a partition structure 24 is provided inside the bin body 2. The partition structure 24 can divide the inner cavity of the bin body 2 into an air inlet cavity 25 and an air exhaust cavity 26, and a first filtering structure 27 is provided between the air inlet cavity 25 and the air exhaust cavity 26. The dust suction port 22 and the dust discharge port 21 of the bin body 2 are communicated with the air inlet cavity 25. The dust suction device 1 further includes a blower 8 provided at the upper part of the bin body 2. The blower 8 includes an air inlet (not shown in the figure) and an air outlet (not shown in the figure). Among them, the air inlet of the blower 8 is communicated with the air exhaust cavity 26.

[0049] In this embodiment, the fan 8 can discharge the air in the inner cavity of the bin body 2, thereby creating a negative pressure in the bin body 2. Then, the waste fiberglass yarn generated during the production process can enter the air inlet cavity 25 of the bin body 2 through the dust suction port 22. The air discharged from the bin body 2 enters the exhaust cavity 26 through the first filtering structure 27 and is then discharged through the air outlet of the fan 8. Exemplarily, a variable-frequency motor is provided inside the fan 8, and the power of the variable-frequency motor can be adjusted. Thus, during the actual production process, the operator can adjust the power of the variable-frequency motor according to the waste fiberglass yarn of different gram weights. In this way, it is beneficial to reduce the energy consumption of the fan 8 and save resources.

[0050] As Figure 3 and Figure 4 shown, in this embodiment, the partition structure 24 can be, for example, a partition board, and the material of the partition board can be, for example, stainless steel, plastic, aluminum alloy, etc. The first filtering structure 27 and the partition structure 24 together form the exhaust cavity 26, and the air in the bin body 2 can be discharged through the exhaust cavity 26. Among them, the first filtering structure 27 can be, for example, an iron filter screen.

[0051] As Figure 4 shown, in one embodiment, a second filtering structure 28 is provided in the exhaust cavity 26, the second filtering structure 28. The second filtering structure 28 and the first filtering structure 26 are arranged in parallel in the exhaust cavity 26 at a preset interval. When the fan 8 operates to discharge the air in the bin body 2 to form a negative pressure, the air passes through the first filtering structure 27 and the second filtering structure 28 respectively. Exemplarily, the first filtering structure 27 and the second filtering structure 28 are inclinedly arranged inside the bin body 2. The inclination angle can be set according to actual needs, for example, it can be 15° to 75°. The first filtering structure 27 and the second filtering structure 28 can be, for example, rectangular iron filter screens, and the two long sides of the rectangular iron filter screens are respectively in contact with the partition boards located in the upper and lower parts. In this way, the fiberglass yarn debris existing in the discharged air can be filtered more effectively, and the influence of the fiberglass yarn debris blocking the air inlet of the fan 8 on the working efficiency of the fan 8 can be avoided. Referring to Figure 4 , a first handle 271 is provided at one end of the first filtering structure 27, a second handle 281 is provided at one end of the second filtering structure 28, and both the first handle 271 and the second handle 281 extend out of the bin body 2. The operator can pull out the first filtering structure 27 and / or the second filtering structure 28 by pulling the first handle 271 and / or the second handle 281 outwards for cleaning or replacement.

[0052] As Figure 6As shown, in one embodiment, the dust suction device 1 includes an exhaust buffer chamber 9, and the exhaust buffer chamber 9 is communicated with the air outlet of the fan 8. An exhaust buffer structure 91 is arranged in the exhaust buffer chamber 9 for reducing the noise when the fan 8 discharges air. The exhaust buffer structure 91 includes a plurality of partition plates 911 arranged in parallel at a preset interval. Each partition plate 911 is provided with an opening 912. Among them, the shape of the opening 912 can be, for example, circular, hexagonal, oval, etc. Exemplarily, the shape of the opening 912 is rectangular. The positions of the openings 912 on two adjacent partition plates 911 are arranged staggeredly, so that the partition plates 911 can effectively reduce the air flow rate.

[0053] As Figure 6 shown, in this embodiment, the number of the partition plates 911 can be set to 3, for example. The openings 912 arranged on each partition plate 911 are staggered to form an S-shaped exhaust passage. The exhaust buffer structure 91 further includes a cover plate 913, and the cover plate 913 is arranged on the upper part of the partition plates 911. When the air is discharged from the air outlet of the fan 8, it passes through the S-shaped exhaust passage. During this process, the arrangement of the multiple partition plates 911 can effectively reduce the wind speed in the exhaust passage, reduce the wind force, and further reduce the working noise when the fan 8 is working.

[0054] As Figure 5 and Figure 6 shown, in one embodiment, a blanking area 72 is arranged at the lower part of the frame body 7 of the dust suction device 1. Baffles 73 are arranged on three sides of the lower part of the frame body 7, and the baffles 73 and the frame body 7 together form the blanking area 72. The blanking area 72 is used for collecting the waste glass fiber yarn dropped from the bin body 2 so that the operator can centrally process the waste glass fiber yarn.

[0055] In this embodiment, a waste yarn storage bag (not shown in the figure) can be placed in the blanking area 72. After the bin body 2 is filled with waste glass fiber yarn, the bin door 3 is opened, and the waste glass fiber yarn in the bin body 2 falls into the waste yarn storage bag in the blanking area 72 under the action of gravity. After the waste yarn storage bag is filled, it is replaced by the operator in time to avoid affecting the discharge efficiency of the waste glass fiber yarn in the bin body 2 of the dust suction device 1.

[0056] In one embodiment, a side plate 74 is arranged on the side where the swinging mechanism 4 is located in the dust suction device 1. The side plate 74 is fixedly connected to the frame body 7, which can protect the swinging mechanism 4 and prevent the swinging mechanism 4 from being damaged due to external forces, which is beneficial to extending the service life of the swinging mechanism 4.

[0057] As Figure 5As shown, in one embodiment, a control panel 11 is provided on one side of the dust suction device 1, which is used to control and adjust the power of the dust suction device 1 and display the working state of the dust suction device 1. The control panel 11 can be, for example, a touch control panel. The operator can turn on and off the dust suction device 1 by touching the control panel 11. In addition, the control panel 11 allows the operator to monitor the working state of the dust suction device 1 in real time, so as to perform timely maintenance when the dust suction device 1 fails.

[0058] In one embodiment, a sensing device is provided in the dust suction device 1. The sensing device can sense whether the bin 2 is full. When the fiberglass waste material sucked into the dust suction device 1 through the dust suction port 22 fills the bin 2, the sensing device controls the driving part 5 to automatically open the bin door 3. Thus, the fiberglass waste material in the bin 2 can be discharged in time through the dust discharge port 21, avoiding affecting the working efficiency of the dust suction device 1.

[0059] The specific working process of the dust suction device 1 of the present invention is as follows: The operator turns on the dust suction device 1 through the control panel 11, and the fan 8 starts to work, pumping out the air inside the bin 2 through the air inlet, so that a negative pressure is formed inside the bin 2. The dust suction port 22 is connected to a dust suction pipe, and the fiberglass waste material enters the dust suction port 22 through the dust suction pipe and then enters the bin 2. During the operation of the dust suction device 1, the air discharged by the fan 8 enters the exhaust cavity 26 through the exhaust port, and the first filtering structure 27 and the second filtering structure 28 filter the discharged air to prevent the fiberglass waste material from blocking the air outlet of the fan 8. The air discharged from the air outlet of the fan 8 enters the exhaust buffer cavity 9 and is discharged through the exhaust buffer channel. When the fan 8 continues to work but the dust suction port 22 can no longer suck in the fiberglass waste material, the sensing device on the loom connected to the dust suction device 1 issues an alarm. At this time, the driving part 5 drives the swing mechanism 4 to move, and the swing arm 41 drives the bin door 3 to open, so that the fiberglass waste material in the bin 2 falls into the blanking area 72, and the operator timely clears the fiberglass waste material in the blanking area 72.

The protection scope of the present invention should not be regarded as limited to the specific forms stated in the embodiments. The protection scope of the present invention also includes equivalent technical means that those skilled in the art can think of according to the inventive concept of the present invention.
