Description

Technical Field

[0001] The present invention relates to the technical field of fabric crushing, and specifically to a device for crushing and recycling non-woven fabric waste edges. Background Art

[0002] Non-woven fabrics are not made through traditional spinning and weaving processes. Instead, textile short fibers or filaments are arranged directionally or randomly to form a fiber web structure, which is then reinforced by mechanical, thermal bonding, or chemical methods. This production process breaks through the traditional textile principle and has the characteristics of a short process flow, high production speed, high output, and low cost. During the processing of non-woven fabrics, waste edges are formed, and it is necessary to crush and recycle them because the crushed non-woven fabric waste edges can be used to produce recycled paper, sound insulation materials, or building insulation materials, etc.

[0003] During the process of crushing non-woven fabrics by a non-woven fabric waste crusher, since non-woven fabrics are composed of polymer materials, these materials are prone to generating fine fiber particles during the crushing process, forming fiber dust. This fiber dust floats with the gas and will float out from the feed inlet. Therefore, a dust-proof curtain is installed at the feed inlet of the non-woven fabric waste crusher. And to facilitate the smooth entry of waste into the crusher, the dust-proof curtain is composed of multiple rubber sheets, which can effectively prevent the dust-proof curtain from blocking the waste from entering the crusher. However, due to the gaps between the multiple rubber sheets, during the process of the crusher crushing non-woven fabric waste, a large amount of fiber dust still diffuses from the feed inlet of the crusher, and the diffused fiber dust has a serious impact on the respiratory system of workers, which may cause symptoms such as sore throat, cough, and asthma. Long-term exposure may also lead to chronic diseases such as pneumoconiosis. Summary of the Invention

[0017] 3. In the present invention, by installing a deceleration component, during the closing process of the cover plate, the hollow ball in the deceleration component will block the smaller-diameter end of the conical tube, enabling the gas in the arc-shaped sleeve to be discharged through the through-hole on the hollow ball, which can slow down the gas discharge speed in the arc-shaped collar, thereby slowing down the rotation speed of the cover plate and the pedal. This can not only prevent the cover plate from hitting and damaging the feed inlet due to too fast a rotation speed, but also prevent the pedal from hitting a person's leg due to too fast a rotation speed.

[0020] 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Example 1: Please refer to Figures 1-4 and Figure 8 . A non-woven waste edge material crushing and recycling device shown in the figure includes a crusher 1. An inlet 2 is fixedly installed outside the crusher 1. The inlet 2 is in an inclined state, aiming to facilitate personnel to put non-woven waste edge materials into the crusher 1. It also includes a dust blocking mechanism for blocking the diffusion of fiber dust from the inlet 2. The dust blocking mechanism is installed outside the inlet 2.

[0022] The dust blocking mechanism includes a cover plate 3 rotatably connected to the crusher 1. The connection between the cover plate 3 and the inlet 2 is in a movable abutting manner. The area of the cover plate 3 is larger than that of the inlet 2. A rubber strip is installed at the joint between the cover plate 3 and the inlet 2 to increase the sealing performance between the cover plate 3 and the inlet 2. Two symmetrically distributed front and rear limit guide seats 4 are fixedly installed at the lower end of the cover plate 3 corresponding to the outside of the inlet 2. A long top rod 5 is installed below the limit guide seats 4. The lower end of the long top rod 5 is hinged to a hinge seat 6.

[0023] The lower end of the hinge seat 6 is fixedly connected to a pedal 7. The pedal 7 is rotatably connected to the crusher 1 through a positioning shaft 8, and the positioning shaft 8 is close to the hinge seat 6. The distance from the positioning shaft 8 to the right end of the pedal 7 is greater than the distance from the positioning shaft 8 to the left end of the pedal 7. This is beneficial for personnel to save effort when stepping on the pedal 7. A roller 9 is rotatably installed inside the limit guide seats 4 corresponding to the upper end of the long top rod 5. The roller 9 can not only prevent the long top rod 5 from disengaging from the limit guide seats 4, but also reduce the friction between the long top rod 5 and the cover plate 3. The connection between the roller 9 and the limit guide seats 4 is in a rolling connection. By rotating the pedal 7, the long top rod 5 can be driven to move upward through the hinge seat 6. The long top rod 5 can drive the cover plate 3 to rotate and open through the roller 9. A socket 10 is movably sleeved outside the roller 9, and the connection between the socket 10 and the crusher 1 is in a fixed connection. The socket 10 can limit the long top rod 5.

[0024] An annular pipe 11 is fixedly installed on the upper end surface of the cover plate 3. A plurality of exhaust pipes 12 are fixedly installed at the lower end of the annular pipe 11 at equal distances, and the exhaust pipes 12 penetrate the cover plate 3. Two symmetrically distributed first conduits 13 are fixedly installed outside the annular pipe 11. A corrugated part 39 is provided on the first conduit 13. The corrugated part 39 is beneficial for the first conduit 13 to adapt to the rotation of the cover plate 3.

One end of the second conduit 14 far from the two first conduits 13 is fixedly connected to a blower 15, and the blower 15 is fixedly installed on the upper end of the crusher 1. The blower 15 blows air above the inlet 2 through the first conduit 13, the second conduit 14 and a plurality of exhaust pipes 12, and can form an air screen above the inlet 2 to prevent fiber dust from diffusing at the inlet 2.

[0025] At the upper end of the crusher 1, a switch assembly is installed corresponding to the left side of the cover plate 3. The switch assembly includes a switch box 32 fixedly installed at the upper end of the crusher 1, and the connection between the switch box 32 and the blower 15 is a fixed connection. A key rod 33 is movably embedded on one side of the switch box 32 close to the cover plate 3. A static contact is arranged in the switch box 32, and a moving contact is arranged on the key rod 33. When the moving contact on the key rod 33 contacts the static contact in the switch box 32, the blower 15 is in an operating state. A gasket 34 is fixedly sleeved on the outer side of the key rod 33.

[0026] A straight spring 35 is movably sleeved on the outer side of the gasket 34, and the two ends of the straight spring 35 are respectively in movable abutment with the switch box 32 and the gasket 34. The straight spring 35 can drive the key rod 33 to move to the right through the gasket 34, so that the moving contact on the key rod 33 moves away from the static contact in the switch box 32. A ball 36 is movably embedded at one end of the key rod 33 away from the switch box 32. An arc driving bar 37 is fixedly sleeved on the outer side of the cover plate 3 corresponding to the key rod 33. A beveled edge portion 38 is arranged at the lower end of the arc driving bar 37, and the ball 36 is in rolling contact with the arc driving bar 37 through the beveled edge portion 38. The ball 36 is used to reduce the friction between the key rod 33 and the arc driving bar 37. The arc driving bar 37 can drive the key rod 33 to move to the left through the beveled edge portion 38.

[0027] Embodiment 2: Please refer to Figure 4 , Figure 4 , Figure 5 , this embodiment further describes Embodiment 1. A positioning component is used to position and support the dust-proof mechanism. The positioning component is installed on the lower side of the dust-proof mechanism. The positioning component includes arc-shaped support rods 16 fixedly installed at the lower end of the cover plate 3. The number of arc-shaped support rods 16 is two groups, and they are symmetrically distributed on the outer side of the feed inlet 2. Card slots 17 are opened on the outer sides of the two arc-shaped support rods 16 close to their lower ends. A pin rod 18 is movably embedded in the card slots 17. The two pin rods 18 are fixedly connected at one end away from the arc-shaped support rods 16. An arc-shaped spring 20 is fixedly installed on the lower side of the pin rod 18. The pin rod 18 is embedded in the card slot 17 under the drive of the arc-shaped spring 20, and can support the cover plate 3 through the arc-shaped support rods 16.

[0028] One end of the arc-shaped spring 20 away from the pin rod 18 is fixedly connected with a positioning block 21, and the connection mode between the positioning block 21 and the feed inlet 2 is a fixed connection. The arc-shaped spring 20 can drive the pin rod 18 to rotate through the positioning block 21. A cap pin 22 is fixedly installed on one side of the pin rod 18 close to the feed inlet 2. A connecting seat 23 is movably sleeved outside the cap pin 22, and the connection mode between the connecting seat 23 and the feed inlet 2 is a fixed connection. The pin rod 18 is rotationally connected to the connecting seat 23 through the cap pin 22. The cap pin 22 can prevent the pin rod 18 from detaching from the connecting seat 23. A stop rod 24 is movably abutted on the upper side of the pin rod 18, and the connection mode between the stop rod 24 and the feed inlet 2 is a fixed connection. The stop rod 24 is located on the right side of the cap pin 22. The long connecting rod 19 is used to simultaneously toggle two pin rods 18.

[0029] Embodiment 3: Please refer to Figure 4 , Figure 7 , Figure 8 , this embodiment further illustrates the second embodiment. A deceleration component is used to decelerate the rotation of the dust-proof mechanism. The deceleration component is installed outside the positioning component. The number of deceleration components is two groups and they are symmetrically distributed. The deceleration component includes a piston 25 fixedly installed at the lower end of the arc-shaped support rod 16. An arc-shaped sleeve 26 is movably sleeved outside the piston 25, and the arc-shaped sleeve 26 is fixedly connected to the crusher 1 and the feed inlet 2 respectively. The outer diameter of the piston 25 is smaller than the inner diameter of the arc-shaped sleeve 26, which can make the piston 25 move smoothly in the arc-shaped sleeve 26. One end of the piston 25 away from the arc-shaped support rod 16 is fixedly connected with a tapered tube 27.

[0030] A hole plate 28 is fixedly embedded inside the arc-shaped sleeve 26 near the tapered tube 27. On the one hand, the hole plate 28 is beneficial to the gas flow inside the arc-shaped sleeve 26, and on the other hand, it is beneficial to limit the hollow ball 30. A positioning rod 29 is fixedly embedded at the center of one side of the hole plate 28 close to the tapered tube 27. A hollow ball 30 is movably sleeved outside the positioning rod 29, and the diameter of the hollow ball 30 is larger than the smaller end diameter of the tapered tube 27. The hollow ball 30 can block the port of the tapered tube 27. The tapered tube 27 is used to prevent the hollow ball 30 from detaching from the arc-shaped sleeve 26. A plurality of through holes 31 are arranged on the outer side of the hollow ball 30 at equal circumferential intervals. The plurality of through holes 31 facilitate the discharge of gas through the hollow ball 30. The positioning rod 29 is beneficial to keep the plurality of through holes 31 on the hollow ball 30 always aligned with the pipe orifice of the tapered tube 27.

[0031] Working principle: when the crusher 1 crushes the non-woven waste, the cover plate 3 presses against the upper end of the feed port 2 under the action of its own gravity, which can effectively prevent the fiber dust from being discharged through the feed port 2. At this time, the ball 36 contacts the bevel 38 of the arc driving strip 37, and the moving contact on the button rod 33 is separated from the static contact in the switch box 32. At this time, the blower 15 is in the shutdown state, which can prevent the fiber dust from diffusing through the feed port 2 and reduce the energy consumption of the equipment. When it is necessary to add non-woven waste to the crusher 1, the person steps on the pedal 7 to rotate the pedal 7 through the positioning shaft 8. During the rotation, the pedal 7 drives the long push rod 5 to move upward through the hinge seat 6. During the upward movement, the long push rod 5 The cover plate 3 is driven to rotate and open by the roller 9. During this process, the arc driving bar 37 drives the button rod 33 to move leftward through the bevel portion 38. The moving contact on the button rod 33 contacts the static contact in the switch box 32, so that the blower 15 is powered on and operates. The blower 15 operates through multiple exhaust pipes 12 to form a wind screen on the upper side of the feed port 2, so that when the cover plate 3 is opened to add material to the crusher 1, the wind screen blocks the fiber dust from diffusing from the feed port 2 to prevent the fiber dust from affecting human health (in the prior art, a cloth bag is tied at the discharge port of the crusher 1, and the crushed non-woven waste edge materials enter the cloth bag under gas drive. On the one hand, the cloth bag can hold non-woven scraps, and on the other hand, it can prevent the fiber dust at the discharge port from diffusing).

[0032] When it is necessary to add non-woven fabric scraps into the crusher 1 multiple times, the person steps on the pedal 7 to rotate the pedal 7 to the bottom. In the process of the arc support rod 16 rotating with the cover plate 3, the pin rod 18 will be embedded in the slot 17 driven by the arc spring 20. Since the pin rod 18 cannot rotate downward due to the obstruction of the blocking rod 24, the arc support rod 16 and the cover plate 3 cannot rotate downward due to the obstruction of the pin rod 18, so that the cover plate 3 can be positioned, which is convenient for the person to add non-woven fabric scraps multiple times. After the feeding is completed, the person rotates the long connecting rod 19 downward. In the process of the long connecting rod 19 driving the pin rod 18 to rotate, the pin rod 18 will drive the arc support rod 16 to move upward through the slot 17 until the pin rod 18 is out of the slot 17. At this time, the cover plate 3 will rotate closed under the action of gravity.

[0033] During the process of the cover plate 3 rotating and closing, the hollow ball 30 will block the smaller-diameter end of the tapered tube 27 under the drive of the airflow in the arc-shaped sleeve 26. At this time, the gas in the arc-shaped sleeve 26 can only be discharged through the multiple through-holes 31 on the hollow ball 30, so as to reduce the gas discharge flow rate of the arc-shaped sleeve 26 and slow down the moving speed of the piston 25 in the arc-shaped sleeve 26, which is beneficial to the slow rotation of the cover plate 3 and the pedal 7. This can not only prevent the cover plate 3 from hitting the feed port 2 and being damaged due to too fast rotation speed, but also prevent the pedal 7 from hitting the legs of personnel due to too fast rotation speed. During the process of the cover plate 3 rotating and opening, the hollow ball 30 will fit against the hole plate 28 under the drive of the airflow. At this time, the gas can quickly enter the inside of the arc-shaped sleeve 26 through the tapered tube 27. And because the diameter of the piston 25 is smaller than the inner diameter of the arc-shaped sleeve 26, the piston 25 can move inside the arc-shaped sleeve 26 at a relatively fast speed, so that the influence of the piston 25 on the opening speed of the cover plate 3 is relatively small.

[0034] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
