Description

Technical Field

[0001] The invention relates to the technical field of glass wool production, and in particular to a 3D glass wool collecting device. Background Art

[0002] The glass wool production line includes automatic feeding system, glass melting furnace, solution fiber centrifuge, cotton collecting device, white cotton pressure coiling machine, curing furnace, cooling conveyor, longitudinal cutting conveyor, edge scraping conveyor, cross-cutting machine, etc. The function of the cotton collecting device is to collect the glass wool output from the centrifuge and convey it to the white cotton pressure coiling machine.

[0003] For example, a Chinese patent with authorization announcement number CN216550158U and authorization announcement date of May 17, 2022 discloses "A cotton collector for rock wool board production". The cotton collecting sleeve on the surface of the cotton collecting rod is used to collect the rock wool on its surface during each cotton collection process, and then the internal mechanism is used to detach the rock wool attached to the end of the cotton collecting rod.

[0004] However, after the doffing rod in the above-mentioned comparative patent rotates to a vertical downward position and the doffing sleeve is at the bottom under the action of gravity, part of the rock wool will still be attached to the cotton collecting rod, resulting in part of the rock plate being compressed at one end of the doffing rod near the middle part as the doffing rod moves to a vertical upward position. This part of the rock wool cannot be doffed by the internal mechanism, and there are deficiencies in its use. Summary of the invention

[0005] The purpose of the present invention is to provide a glass wool 3D stereoscopic cotton collecting device, which has the function of improving the cotton collecting effect.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a glass wool 3D stereoscopic cotton collecting device, comprising a frame, a cotton collecting chamber arranged on one side of the frame, a conveyor belt arranged on the other side of the frame, and a cotton collecting mechanism arranged in the middle of the frame and realizing the adsorption of glass wool fiber filaments in the cotton collecting chamber to a set thickness and then converting them into a glass fiber cotton layer and conveying them to the conveyor belt. The cotton collecting mechanism comprises a negative pressure pipe arranged in the middle of the frame, an annular rotating frame rotatably connected to the negative pressure pipe, a plurality of cotton collecting mesh plates arranged on the periphery of the annular rotating frame and connected end to end, a negative pressure cover connected to the negative pressure pipe, and a power component arranged on the frame and driving the annular rotating frame to rotate. A cotton outlet is formed on the cotton collecting chamber and is embedded in the upper left half of the periphery of the annular rotating frame. The negative pressure cover extends from one end of the negative pressure pipe away from the cotton collecting mesh plate and corresponds to the range of the cotton outlet.

[0007] By adopting the above technical scheme, when the centrifugally stretched glass fiber yarn is transported to the cotton collecting chamber, the negative pressure device is connected to the negative pressure pipe, so that the glass fiber yarn is adsorbed by the negative pressure to the surrounding side of the cotton collecting mesh plate at the corresponding negative pressure cover and gradually adsorbed to form a glass fiber cotton layer of a certain thickness. The glass fiber cotton layer is separated from the adsorption range of the negative pressure cover after the annular rotating frame, so that the glass fiber cotton layer is conveniently separated from the cotton collecting mesh plate and transported to the conveyor belt, and then transmitted to the next process through the conveyor belt, thereby finally improving the cotton collecting effect; at the same time, the 3D structure setting of the cotton collecting mechanism makes the cotton collecting process smoother and more efficient.

[0008] The present invention is further configured such that: the height of the upper surface of the conveyor belt is the same as the height of the rotation axis of the annular rotating frame, and an inclined guide mechanism extending to the side close to the annular rotating frame is provided at one end of the conveyor belt close to the annular rotating frame, and the inclined guide mechanism includes an inclined guide plate whose lower end is rotatably connected to both sides of the conveyor belt and whose upper end abuts against the peripheral side of the cotton collecting mesh plate, and a linkage component which is provided between the inclined guide plate and the frame of the conveyor belt and drives the inclined guide plate to swing back and forth and drives the glass fiber cotton layer to separate from the cotton collecting mesh plate.

[0009] By adopting the above technical solution, when the glass fiber cotton layer is attached to the peripheral side of the cotton collecting mesh plate, there is a certain adhesion force even if it leaves the negative pressure range of the negative pressure cover. At this time, by setting an inclined guide mechanism, the linkage assembly drives the inclined guide plate to swing back and forth, so that the inclined guide plate applies a pulling force to the bottom of the glass fiber cotton layer, which makes it convenient for the glass fiber cotton layer to detach from the cotton collecting mesh plate, thereby making it convenient for the glass fiber cotton layer to enter the conveyor belt.

[0010] The present invention is further configured as follows: the driven shaft of the transmission belt is close to the annular rotating frame and protrudes from the frame at both ends, and the linkage assembly includes a driving gear arranged on the driven shaft of the transmission belt and having an arc-shaped rack on the circumferential side, a driving ring slidably arranged on the frame of the transmission belt and having a first spur rack on the upper and lower sides inside, a second spur rack arranged on the top of the driving ring, and a driven gear arranged on both sides of the inclined guide plate and surrounding the rotation axis of the inclined guide plate; during the rotation of the driving gear, when the arc-shaped rack of the driving gear and the first spur rack on the upper side of the driving ring are disengaged, the arc-shaped rack meshes with the first spur rack on the lower side of the driving ring, and when the arc-shaped rack of the driving gear and the first spur rack on the lower side of the driving ring are disengaged, the arc-shaped rack meshes with the first spur rack on the upper side of the driving ring, and the driven gear and the second spur rack mesh.

[0011] By adopting the above technical solution, during the operation of the conveyor belt, the driving gear is driven to rotate through its driven shaft, and the driving gear drives the driving ring to move back and forth linearly during the rotation. The second spur rack on the driving ring drives the driving gear to swing back and forth, thereby driving the inclined guide plate to swing back and forth, so that the inclined guide plate applies a pulling force to the bottom of the glass fiber cotton layer, which facilitates the separation of the glass fiber cotton layer from the cotton collecting mesh plate.

[0012] The present invention is further configured as follows: the annular rotating frame includes two rotating disks rotatably connected to the circumference of the negative pressure pipe, and two annular shelf rings arranged on the inner sides of the rotating disks; the two ends of the cotton collecting mesh plate are arranged on the annular shelf rings; an elastic connection mechanism is arranged between the ends of the cotton collecting mesh plate and the annular shelf rings so that the cotton collecting mesh plate can be extended and retracted along the radial direction of the annular rotating frame under the action of external force; when the cotton collecting mesh plate rotates to the bottom of the annular rotating frame, the gravity of the cotton collecting mesh plate is less than the elastic connection mechanism fixing the cotton collecting mesh plate A disengaging mechanism is provided between the frame and any one of the cotton collecting screens, which can disengage the cotton collecting screen after overcoming the elastic force of the elastic connecting mechanism when the cotton collecting screen is rotated to the position below the annular rotating frame; the negative pressure pipe is provided with a brush mechanism for abutting against the inner side of the cotton collecting screen near the end of the inclined guide plate; the frame is provided with a fluff suction mechanism located below the annular rotating frame, and the fluff suction mechanism allows the sucked fluff to flow out from the gap between the cotton collecting screen disengaged by the disengaging mechanism and the nearby cotton collecting screen.

[0013] By adopting the above technical scheme, during the process of glass fiber filaments being adsorbed on the cotton collecting mesh plate, part of the glass fiber filaments will adhere to the cotton collecting mesh plate and are not easy to detach. At this time, the glass fiber filaments on the inner side of the cotton collecting mesh plate can be brushed off by setting the brush mechanism, and the glass fiber filaments brushed off into balls will fall to the bottom of the annular rotating frame. At this time, the elastic connection mechanism between the cotton collecting mesh plate and the annular shelving ring and the disengagement mechanism are used to make the cotton collecting mesh plate that is rotated to the bottom of the annular rotating frame overcome the elastic connection mechanism and then disengage, so that there is a gap between adjacent cotton collecting mesh plates, and finally the fluff suction mechanism is used to extract the balled glass fiber filaments, and finally the glass fiber filaments that are attached to the cotton collecting mesh plate and are not easy to detach can be reduced, thereby ensuring the effect of making the glass fiber filaments adhere to the cotton collecting mesh plate under the action of negative pressure; at the same time, the disengagement mechanism is set at the bottom of the annular rotating frame, and at this time, part of the force of the elastic connection mechanism of the cotton collecting mesh plate will also be offset by gravity, thereby reducing the force of the disengagement mechanism when it detaches from the cotton collecting mesh plate.

[0014] The present invention is further configured as follows: two mutually parallel telescopic holes are arranged at the end of the annular supporting ring corresponding to the cotton collecting mesh plate, and a mounting hole is arranged at the end of the cotton collecting mesh plate corresponding to the telescopic hole, and the elastic connecting mechanism includes a connecting screw which passes through the mounting hole and the telescopic hole in sequence, a compression spring sleeved on the connecting screw, a gasket sleeved on the connecting screw, and two adjusting nuts threadedly connected to the connecting screw, the two ends of the compression spring are elastically pressed between the inner ring of the annular supporting ring and the gasket, and the diameter of the end of the connecting screw close to the cotton collecting mesh plate is larger than the aperture of the mounting hole.

[0015] By adopting the above technical solution, after overcoming the force of the compression spring, the cotton collecting screen can be separated from the annular rotating frame at the disengagement mechanism, and the initial elastic force of the compression spring can be adjusted by adjusting the position of the two adjusting nuts.

[0016] The present invention is further configured as follows: the disengagement mechanism includes an "L"-shaped guide shaft arranged at both ends of the cotton collecting mesh plate, and a guide rail arranged on the frame and having a guide groove, the rail groove in the guide rail gradually moves away from the annular rotating frame, and when the cotton collecting mesh plate rotates to the lower position along with the annular rotating frame, the guide shaft enters from one end of the guide rail, and under the action of the guide rail, overcomes the force of the elastic connection mechanism, so that the cotton collecting mesh plate is disengaged.

[0017] By adopting the above technical solution, when the driving shaft enters the guide track, the guide track gradually moves away from the annular rotating frame, thereby overcoming the elastic force of the elastic connection mechanism, so that the cotton collecting mesh plate is separated from the annular rotating frame, and a gap is left between the cotton collecting mesh plate and the adjacent cotton collecting mesh plates, which facilitates the suction treatment of the clumped glass fiber filaments through the lint suction mechanism.

[0018] The present invention is further configured as follows: the brush mechanism comprises a bracket arranged on the negative pressure tube, and a brush arranged on the bracket and abutting against the inner side of the cotton collecting mesh plate.

[0019] By adopting the above solution, the brush of the brushing mechanism can brush off the glass fiber filaments on the inner side of the cotton collecting mesh plate.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment: A 3D glass wool collection device, such as Figure 1 and Figure 2 As shown, it includes a frame 1, a cotton collecting chamber 2 arranged on one side of the frame 1, a conveyor belt 3 arranged on the other side of the frame 1, and a cotton collecting mechanism arranged in the middle of the frame 1 and capable of adsorbing the glass wool fiber filaments in the cotton collecting chamber 2 to a set thickness to convert them into a glass fiber cotton layer and transporting them to the conveyor belt 3.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the cotton collecting mechanism includes a negative pressure pipe 41 arranged in the middle of the frame 1, an annular rotating frame 42 rotatably connected to the negative pressure pipe 41, a plurality of cotton collecting mesh plates 43 arranged on the periphery of the annular rotating frame 42 and connected end to end, a negative pressure cover 44 connected to the negative pressure pipe 41, and a power component 45 arranged on the frame 1 and driving the annular rotating frame 42 to rotate. A cotton outlet is formed on the cotton collecting chamber 2 and is embedded in the upper left half of the circumference of the annular rotating frame 42; the annular rotating frame 42 includes two rotating disks 421 rotatably connected to the circumference of the negative pressure tube 41, two annular supporting rings 422 arranged on the inner sides of the rotating disks 421, and both ends of the cotton collecting mesh plate 43 are arranged on the annular supporting rings 422; the negative pressure cover 44 extends from one end of the negative pressure tube 41 to the cotton collecting mesh plate 43 and corresponds to the range of the cotton outlet; the power assembly 45 includes a gear ring 451 arranged on the circumference of one end of the annular rotating frame 42, a reduction motor 452 arranged on the frame 1, and a driving gear 453 arranged on the output shaft of the reduction motor 452 and meshing with the gear ring 451.

[0034] like Figure 1 and Figure 3As shown, the height of the upper surface of the conveyor belt 3 is the same as the height of the rotation axis of the annular rotating frame 42, and the end of the conveyor belt 3 close to the annular rotating frame 42 is provided with an inclined guide mechanism extending to the side close to the annular rotating frame 42, and the inclined guide mechanism includes an inclined guide plate 51 whose lower end is rotatably connected to both sides of the conveyor belt 3 and whose upper end is in contact with the side of the cotton collecting mesh 43, and a linkage component 52 which is arranged between the inclined guide plate 51 and the frame of the conveyor belt 3 and drives the inclined guide plate 51 to swing back and forth and drives the glass fiber cotton layer to separate from the cotton collecting mesh 43. The driven shaft of the transmission belt 3 is close to the annular rotating frame 42 and protrudes from the frame at both ends. The linkage assembly 52 includes a driving gear 521 arranged on the driven shaft of the transmission belt 3 and having an arc-shaped rack 5211 on the circumferential side, a driving ring 522 slidably arranged on the frame of the transmission belt 3 and having first straight racks 5221 arranged on the upper and lower sides of the interior, a second straight rack 523 arranged on the top of the driving ring 522, and a driven gear 524 arranged on both sides of the inclined guide plate 51 and surrounding the rotation axis of the inclined guide plate 51; During the rotation process of 21, when the arc-shaped rack 5211 of the driving gear 521 and the first straight rack 5221 on the upper side of the driving ring 522 are disengaged, the arc-shaped rack 5211 is meshed with the first straight rack 5221 on the lower side of the driving ring 522; when the arc-shaped rack 5211 of the driving gear 521 and the first straight rack 5221 on the lower side of the driving ring 522 are disengaged, the arc-shaped rack 5211 is meshed with the first straight rack 5221 on the upper side of the driving ring 522, and the driven gear 524 is meshed with the second straight rack 523.

[0035] like Figure 1 , Figure 2 As shown, an elastic connection mechanism 6 is provided between the end of the cotton collecting mesh plate 43 and the annular shelf ring 422, so that the cotton collecting mesh plate 43 can be extended and retracted along the radial direction of the annular rotating frame 42 under the action of an external force. When the cotton collecting mesh plate 43 rotates to the bottom of the annular rotating frame 42, the gravity of the cotton collecting mesh plate 43 is less than the force of the elastic connection mechanism 6 when fixing the cotton collecting mesh plate 43. A spring is provided between the frame 1 and any one of the cotton collecting mesh plates 43 when the cotton collecting mesh plate 43 rotates to the annular rotating frame 42. The disengaging mechanism 7 is disposed below the rotating frame 42 to overcome the elastic force of the elastic connecting mechanism 6 so as to disengage the cotton collecting mesh plate 43. The negative pressure tube 41 is provided with a brush mechanism 8 for abutting against the inner side of the cotton collecting mesh plate 43 near the end of the inclined guide plate 51. The frame 1 is provided with a fluff suction mechanism 9 located below the annular rotating frame 42. The fluff suction mechanism 9 allows the sucked fluff to flow out from the gap between the cotton collecting mesh plate 43 disengaged by the disengaging mechanism 7 and the nearby cotton collecting mesh plate 43.

[0036] like Figure 2 and Figure 4As shown, two mutually parallel telescopic holes 4221 are provided at the end of the annular resting ring 422 corresponding to the cotton collecting mesh plate 43, and a mounting hole 431 is provided at the telescopic hole 4221 of the cotton collecting mesh plate 43. The elastic connecting mechanism 6 includes a connecting screw 61 which passes through the mounting hole 431 and the telescopic hole 4221 in sequence, a compression spring 62 sleeved on the connecting screw 61, a gasket 63 sleeved on the connecting screw 61, and two adjusting nuts 64 threadedly connected to the connecting screw 61. Both ends of the compression spring 62 are elastically pressed between the inner ring of the annular resting ring 422 and the gasket 63, and the diameter of the end of the connecting screw 61 close to the cotton collecting mesh plate 43 is larger than the aperture of the mounting hole 431.

[0037] like Figure 1 , Figure 2 and Figure 5 As shown, the disengagement mechanism 7 includes an "L"-shaped guide shaft 71 arranged at both ends of the cotton collecting mesh plate 43, and a guide track 72 arranged on the frame 1 and having a guide groove. The track groove in the guide track 72 gradually moves away from the annular rotating frame 42. When the cotton collecting mesh plate 43 rotates to the lower position along with the annular rotating frame 42, the guide shaft 71 enters from one end of the guide track 72, and under the action of the guide track 72, overcomes the force of the elastic connecting mechanism 6, so that the cotton collecting mesh plate 43 is disengaged.

[0038] like Figure 1 and Figure 2 As shown, the brush mechanism 8 includes a bracket 81 arranged on the negative pressure tube 41 and a brush 82 arranged on the bracket 81 and abutting against the inner side of the cotton collecting mesh plate 43 .

[0039] like Figure 1 As shown, the lint suction mechanism 9 includes a collecting hood 91 arranged on the frame 1 and corresponding to the bottom of the annular rotating frame 42, an exhaust fan 92 arranged on the frame 1 and connected to the collecting hood 91, and a dust collecting bag 93 arranged on the air outlet end of the exhaust fan 92.

[0040] Implementation effect: When the centrifugally stretched glass fiber yarn is transported to the cotton collecting chamber 2, a negative pressure device is connected to the negative pressure pipe 41, so that the glass fiber yarn is negatively adsorbed to the surrounding side of the cotton collecting mesh plate 43 at the corresponding negative pressure cover 44 and gradually adsorbed to form a glass fiber cotton layer of a certain thickness. The glass fiber cotton layer is separated from the adsorption range of the negative pressure cover 44 after the annular rotating frame 42, so that the glass fiber cotton layer is conveniently separated from the cotton collecting mesh plate 43 and transported to the conveyor belt 3, and then transmitted to the next process through the conveyor belt 3, thereby finally improving the cotton collecting effect; at the same time, the 3D structure setting of the cotton collecting mechanism makes the cotton collecting process smoother and more efficient.

[0041] When the glass fiber wool layer is attached to the side of the cotton collecting mesh plate 43, even if it leaves the negative pressure range of the negative pressure cover 44, there is still a certain adhesion force. At this time, by setting an inclined guide mechanism, the linkage component 52 drives the inclined guide plate 51 to swing back and forth, so that the inclined guide plate 51 applies a pulling force to the bottom of the glass fiber wool layer, which facilitates the glass fiber wool layer to be separated from the cotton collecting mesh plate 43, thereby facilitating the glass fiber wool layer to enter the conveyor belt 3. During the operation of the conveyor belt 3, the driven shaft drives the driving gear 521 to rotate, and the driving gear 521 drives the driving ring 522 to reciprocate linearly left and right during the rotation. The second straight rack 523 on the driving ring 522 drives the driving gear 521 to swing back and forth left and right, thereby driving the inclined guide plate 51 to swing back and forth, so that the inclined guide plate 51 applies a pulling force to the bottom of the glass fiber wool layer, which facilitates the glass fiber wool layer to be separated from the cotton collecting mesh plate 43.

[0042] In the process of glass fiber filaments being adsorbed on the cotton collecting mesh plate 43, some of the glass fiber filaments will adhere to the cotton collecting mesh plate 43 and will not be easily detached. At this time, the glass fiber filaments on the inner side of the cotton collecting mesh plate 43 can be brushed off by setting the brush mechanism 8. The glass fiber filaments brushed off into a ball will fall to the bottom of the annular rotating frame 42. At this time, the elastic connection mechanism 6 between the cotton collecting mesh plate 43 and the annular resting ring 422 is used in conjunction with the disengagement mechanism 7, so that the cotton collecting mesh plate 43 that has been rotated to the bottom of the annular rotating frame 42 overcomes the elastic connection mechanism 6. The disengagement allows gaps to exist between adjacent cotton collecting mesh plates 43, and ultimately cooperates with the lint suction mechanism 9 to extract the clumped glass fiber filaments, which can ultimately reduce the glass fiber filaments that are attached to the cotton collecting mesh plates 43 and are not easy to detach, thereby ensuring that the glass fiber filaments are attached to the cotton collecting mesh plates 43 under the action of negative pressure; at the same time, the disengagement mechanism 7 is arranged at the bottom of the annular rotating frame 42, and at this time, part of the force of the elastic connection mechanism 6 of the cotton collecting mesh plate 43 will also be offset by gravity, thereby reducing the force of the disengagement mechanism 7 when it detaches from the cotton collecting mesh plate 43.
