[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-9 As shown, a dust removal and sterilization equipment for non-woven fabric processing includes a frame 1, on which a symmetrically distributed clamping assembly is provided. The clamping assembly includes a plurality of base plates 122 movably mounted on the frame 1, and cutting knives 126 are symmetrically and movably provided on the base plates 122. A channel for the flow of heating gas is provided on the base plate 122, and an air outlet 125 is provided at the bottom of the base plate 122. The base plate 122 moves along a predetermined path to clamp, pull and heat the non-woven fabric, and the cutting knife 126 moves to cut the non-woven fabric.

[0031] Specifically, the frame 1 is provided with a clamping roller 13 for guiding the non-woven fabric, the frame 1 is provided with a winding rod 135 for winding the non-woven fabric, the frame 1 is provided with a mounting rod 133, the mounting rod 133 is provided with a cutting knife 134 for cutting the non-woven fabric, and the interior of the bottom plate 122 is provided with an electric heating wire, and the bottom plate 122 is electrically connected to the inner wall of the frame 1 when it moves to the middle of the frame 1.

[0032] Furthermore, when working, the end roll of the non-woven fabric is fed into the frame 1 and passes through the clamping roller 13. The bottom plates 122 of the two clamping assemblies distributed above and below in the frame 1 move according to a predetermined path. The upper and lower corresponding bottom plates 122 approach the non-woven fabric, and the hot air flows into the bottom plate 122 to preheat the bottom plate 122. The airflow flowing out from the upper and lower bottom plates 122 blows on the two surfaces of the non-woven fabric to blow off some of the attachments on the non-woven fabric. Then the upper and lower bottom plates 122 cooperate to clamp the non-woven fabric and pull the non-woven fabric to move. The bottom plate 122 moves to the frame. 1, the bottom plate 122 is electrically connected to the inside of the frame 1, and the electric heating wire inside the bottom plate 122 is energized to heat the bottom plate 122. The temperature of the bottom plate 122 gradually rises to sterilize the non-woven fabric. At the same time, the non-woven fabric is affected by the higher temperature of the bottom plate 122, and part of the surface of the non-woven fabric is in a molten state. At this time, the cutting knife 126 inside the bottom plate 122 moves to trim the non-woven fabric, which can greatly reduce the hair scraps generated during the cutting process. The separated non-woven fabric is then manually wound and fixed on the reeling rod 135, and the reeling rod 135 reels the non-woven fabric.

[0033] Furthermore, the cutting knife 134 in the above embodiment may be an electric scissors, or other existing devices capable of cutting non-woven fabrics.

[0034] In the above technical solution, when working, the end of the non-woven fabric is fed into the frame 1, and the bottom plates 122 of the two clamping assemblies distributed above and below in the frame 1 move according to a predetermined path. The upper and lower corresponding bottom plates 122 approach the non-woven fabric, and the hot air flow enters the bottom plate 122 to preheat the bottom plate 122. The air flow flowing out from the upper and lower bottom plates 122 blows on the two surfaces of the non-woven fabric to blow off some attachments on the non-woven fabric. Then the upper and lower bottom plates 122 cooperate to clamp the non-woven fabric and pull the non-woven fabric to move. The bottom plate 122 gradually heats up during the movement to disinfect the non-woven fabric. At the same time, the non-woven fabric is affected by the higher temperature bottom plate 122, and part of the surface of the non-woven fabric is in a molten state. At this time, the cutting knife 126 inside the bottom plate 122 moves to trim the non-woven fabric, which can greatly reduce the lint generated during the cutting process.

[0035] As a further embodiment provided by the present invention, the channel inside the bottom plate 122 is provided with an air inlet 123 distributed opposite to the air outlet 125. The air outlet 125 is specifically U-shaped and points toward the non-woven fabric.

[0036] Specifically, the interior of the channel is provided with a guide plate 124 for guiding the airflow to flow toward the middle of the bottom plate 122, and a slope is provided near the air outlet 125 in the channel. The slope and the air outlet 125 cooperate to form an inclined U-shaped flow channel to guide the airflow to blow obliquely on the surface of the non-woven fabric and blow the non-woven fabric surface clean. A channel for the flow of hot air is provided on the inner wall of the frame 1.

[0037] Furthermore, in the process of the bottom plate 122 approaching the non-woven fabric, a hot air flow is injected into the air inlet 123 on the bottom plate 122 from the inner wall of the frame 1, and the hot air flow enters the bottom plate 122 along the air inlet 123 and is guided by the guide plate 124 to flow to the middle part of the bottom plate 122, preheating the bottom plate 122, and then flows along the slope close to the air outlet 125, enters the air outlet 125, and along the inclined U-shaped flow channel formed by the slope and the air outlet 125, the hot air flow is blown obliquely toward the non-woven fabric to blow off the attachments on the surface of the non-woven fabric.

[0038] As another embodiment further provided by the present invention, an air blast port is provided on the inner wall of the frame 1 on one side close to the air outlet 125 , and a dust suction port 14 is provided on the other side.

[0039] Specifically, the air blast port is connected to a blower for blowing in disinfecting gas, and the dust suction port 14 is connected to a high-power dust collector.

[0040] Furthermore, during the movement of the non-woven fabric, the blower blows disinfectant gas into the inside of the frame 1, and the disinfectant gas blows the non-woven fabric to blow off the attachments on the non-woven fabric. At the same time, the vacuum cleaner receives the disinfectant gas blown through the non-woven fabric through the suction port 14 and sucks away the used disinfectant gas and the attachments therein.

[0041] As another embodiment further provided by the present invention, the frame 1 is symmetrically provided with first guide grooves 131 corresponding to the clamping components, and the bottom plate 122 moves along the first guide grooves 131 to clamp and pull the non-woven fabric.

[0042] Specifically, the first guide groove 131 is a pentagon with three right angles at its inner angles. The first guide groove 131 has two horizontal straight sides, two vertical straight sides and one oblique side. A movable seat 121 is provided on the bottom plate 122. The movable seat 121 is provided with a rectangular guide block 138 adapted to the first guide groove 131. The guide block 138 is symmetrically provided with slopes to adapt to the oblique side of the first guide groove 131.

[0043] Furthermore, in the process of the movable seat 121 moving with the base plate 122, the guide block 138 first cooperates with the oblique side of the first guide groove 131 to guide the movable seat 121 and the base plate 122 to move, and the base plate 122 approaches the non-woven fabric. When the base plate 122 is close to the non-woven fabric, the guide block 138 moves to the connection between the oblique side of the first guide groove 131 and the horizontal straight side, and then the guide block 138 cooperates with the horizontal straight side of the first guide groove 131 to guide the movable seat 121 and the base plate 122 to move horizontally, and clamp and pull the non-woven fabric to move horizontally, and then the guide block 138 cooperates with the vertical straight side of the first guide groove 131 to guide the movable seat 121 and the base plate 122 to move away from the non-woven fabric, and then moves to another horizontal straight side, and then moves to another vertical straight side, and gradually enters the oblique side of the first guide groove 131.

[0044] Furthermore, the movement of the movable seat 121 in the above embodiment can be undertaken by a conveyor belt with the same moving trajectory as the first guide groove 131. The guide block 138 on the movable seat 121 is rotatably installed on the conveyor belt. When the conveyor belt moves, the movable seat 121 is driven to move through the guide block 138. The guide block 138 cooperates with the first guide groove 131 to keep the movable seat 121 and the base plate 122 in a horizontal state at all times. It can also be a structure that can be obtained by other technical personnel in this field based on common technical knowledge.

[0045] As another embodiment further provided by the present invention, a second guide groove 132 for guiding the movement of the cutting knife 126 is provided on the frame 1 , and a tenon rod 127 adapted to the second guide groove 132 is provided on the cutting knife 126 .

[0046] Specifically, the second guide groove 132 is V-shaped, and a slope is provided on a side of the second guide groove 132 .

[0047] Furthermore, as the base plate 122 moves along a predetermined path, the tenon rod 127 on the base plate 122 gradually becomes aligned with and inserted into the second guide groove 132. The base plate 122 continues to move, and the tenon rod 127 moves along the V-shaped second guide groove 132, driving the cutting knife 126 to move back and forth once. The cutting knife 126 cuts off the non-woven fabric, and then the tenon rod 127 leaves the second guide groove 132 along the slope on the side of the second guide groove 132.

[0048] As another embodiment further provided by the present invention, a limit block 128 is provided on the tenon rod 127 for preventing it from moving up and down, and the tenon rod 127 extends into the second guide groove 132 to unlock the tenon rod 127.

[0049] Specifically, the interior of the base plate 122 is provided with a locking groove 136 adapted to the limit block 128 and a movable groove 137 for the limit block 128 to move. A self-elastic telescopic rod is provided between the limit block 128 and the cutting knife 126. The diameter of the tenon rod 127 is greater than the width of the first guide groove 131, which can prevent the tenon rod 127 from being embedded in the first guide groove 131 when passing through the first guide groove 131.

[0050] Furthermore, during the movement of the bottom plate 122, the self-elastic telescopic rod pushes the tenon rod 127, the tenon rod 127 abuts against the inner wall of the frame 1, the limit rod is in the locking groove 136, the cutting knife 126 is locked, and when the tenon rod 127 is facing the second guide groove 132, the self-elastic telescopic rod pushes the tenon rod 127, the self-elastic telescopic rod extends, the tenon rod 127 is inserted into the second guide groove 132, the limit block 128 moves from the locking groove 136 to the movable groove 137, and the bottom plate 122 is locked. Continuing to move, the tenon rod 127 moves along the V-shaped second guide groove 132 and drives the cutting knife 126 to move back and forth once. The cutting knife 126 cuts the non-woven fabric, and the limit block 128 moves up and down in the movable groove 137 and returns to the position facing the locking groove 136. Then the tenon rod 127 leaves the second guide groove 132 along the slope on the side of the second guide groove 132, the self-elastic telescopic rod is compressed, the limit block 128 returns to the locking groove 136, and the cutting knife 126 is locked.

[0051] As another embodiment further provided by the present invention, knocking rods 111 for knocking non-woven fabrics are symmetrically and movably provided on the frame 1, and the multiple bottom plates 122 move to make the two knocking rods 111 move intermittently.

[0052] Specifically, a spring is provided between the knocking rod 111 located above the non-woven fabric and the frame 1 , and the elastic modulus of the spring is relatively small, and can only support the knocking rod 111 located above the non-woven fabric to reset.

[0053] Furthermore, during the movement of the multiple base plates 122, the two knocking rods 111 move intermittently and alternately, knocking the non-woven fabric, causing the non-woven fabric to shake violently and shake off the attachments on it. At the same time, the blower blows disinfection gas into the inside of the frame 1, and the disinfection gas blows the non-woven fabric to blow off the attachments on the non-woven fabric. At the same time, the vacuum cleaner receives the disinfection gas blown through the non-woven fabric through the suction port 14, and sucks away the used disinfection gas and the attachments therein.

[0054] As another embodiment further provided by the present invention, a knocking block 113 corresponding to the knocking rod 111 is provided on the frame 1 , and a supporting rod 112 for supporting the knocking block 113 is provided on the knocking rod 111 .

[0055] Specifically, the supporting rod 112 is a self-elastic telescopic rod, and a rubber block is provided on the top of the supporting rod 112.

[0056] Furthermore, during the movement of the base plate 122, the knocking block 113 hits the rubber block on the top of the supporting rod 112 on the knocking rod 111, and the knocking block 113 maintains contact with the supporting rod 112 for a certain period of time, and maintains a certain force to continuously output, so that the supporting rod 112 is compressed, and then the supporting rod 112 pushes the knocking rod 111 to move and extend. Based on the continuous force of the knocking rod 111, the knocking rod 111 collides with the non-woven fabric, causing the non-woven fabric to shake violently and shake off the attachments on the non-woven fabric. Although the kinetic energy output by the knocking block 113 will be lost in the process of dry transfer, the retractable supporting rod 112 and the rubber block at the end of the supporting rod 112 can reduce the damage during the collision between the knocking block 113 and the knocking rod 111, and extend the adaptability life of the knocking block 113 and the knocking rod 111. At the same time, the rubber block can greatly reduce the noise generated during the collision.

[0057] As another embodiment further provided by the present invention, the frame 1 is symmetrically provided with discs 116 for driving the striking block 113 to move and rotate synchronously, and the two discs 116 are respectively movably provided with an upper push block 118 and a lower push block 119 for contacting the bottom plate 122.

[0058] Specifically, a connecting rod 114 is provided on the knocking block 113, the middle part of the connecting rod 114 is rotatably installed on the frame 1, a torsion spring is provided between the connecting rod 114 and the frame 1, and a dial wheel 115 for toggling the connecting rod 114 is provided on the disc 116. A rocker 117 is movably provided between the upper push block 118 and the corresponding disc 116, and between the lower push block 119 and the corresponding disc 116. The upper push block 118 and the lower push block 119 are both provided with a slope for contacting the corresponding bottom plate 122, and a spring is provided between the upper push block 118 and the frame 1, and between the lower push block 119 and the frame 1.

[0059] Furthermore, during the movement of the base plate 122, the base plate 122 moves along the slope on the upper push block 118 or the lower push block 119, and then drives the two discs 116 to rotate through the rocker 117, and the disc 116 drives the dial wheel 115 to rotate, and the dial wheel 115 drives the connecting rod 114 to move the knocking block 113 away from the knocking rod 111. The torsion spring between the connecting rod 114 and the frame 1 twists, and the disc 116 continues to rotate. The connecting rod 114 separates from the dial wheel 115, and the torsion spring drives the knocking block 113 to move and collide with the supporting rod 112, and then pushes the knocking rod 111 to collide with the non-woven fabric.

[0060] Furthermore, in the above embodiment, the two discs 116 may be caused to rotate synchronously by providing a chain between the two discs 116, and the chain may be in the shape of an "8"; or a pair of meshing gears capable of transmitting kinetic energy may be provided between the two discs 116; or other structures that can be obtained by those skilled in the art based on common technical knowledge.

[0061] As another embodiment further provided by the present invention, the upper push block 118 cooperates with the corresponding bottom plate 122 , and the lower push block 119 cooperates with the corresponding bottom plate 122 to enable the two disks 116 to rotate continuously.

[0062] Specifically, there is an angular difference between the two disks 116 .

[0063] Furthermore, when working, the end roll of the non-woven fabric is fed into the frame 1 and passes through the clamping roller 13. The bottom plates 122 of the two clamping assemblies distributed above and below in the frame 1 move with the movable seat 121. The guide block 138 first cooperates with the oblique edge of the first guide groove 131 to guide the movable seat 121 and the bottom plate 122 to move. The bottom plate 122 approaches the non-woven fabric, and the hot air flow is injected into the air inlet 123 on the bottom plate 122 from the inner wall of the frame 1. The hot air flow enters the bottom plate 122 along the air inlet 123 and is guided by the guide piece 124 to flow to the middle part of the bottom plate 122 to preheat the bottom plate 122. Then, it flows along the slope near the air outlet 125 and enters the air outlet 125. Along the inclined U-shaped flow channel formed by the slope and the air outlet 125, the hot air flow is blown obliquely toward the non-woven fabric to blow off the attachments on the surface of the non-woven fabric and preheat the non-woven fabric.

[0064] When the bottom plate 122 is in close contact with the non-woven fabric, the guide block 138 moves to the connection between the oblique side and the horizontal straight side of the first guide groove 131, and then the guide block 138 cooperates with the horizontal straight side of the first guide groove 131 to guide the movable seat 121 and the bottom plate 122 to move horizontally, and clamps and pulls the non-woven fabric to move horizontally. When the bottom plate 122 moves to the middle of the frame 1, the bottom plate 122 is electrically connected to the inside of the frame 1, and the electric heating wire inside the bottom plate 122 is energized to heat the bottom plate 122. The temperature of the bottom plate 122 gradually rises, sterilizing the non-woven fabric. At the same time, the non-woven fabric is affected by the higher temperature of the bottom plate 122, and part of the surface of the non-woven fabric is in a molten state.

[0065] During the movement of the bottom plate 122, the self-elastic telescopic rod pushes the tenon rod 127, the tenon rod 127 rests on the inner wall of the frame 1, the limit rod is in the locking groove 136, the cutting knife 126 is locked, and when the tenon rod 127 is facing the second guide groove 132, the self-elastic telescopic rod pushes the tenon rod 127, the self-elastic telescopic rod extends, the tenon rod 127 is inserted into the second guide groove 132, the limit block 128 moves from the locking groove 136 to the movable groove 137, and the bottom plate 122 continues to move. The tenon rod 127 moves along the V-shaped second guide groove 132 and drives the cutting knife 126 to move back and forth once. The cutting knife 126 cuts the non-woven fabric. The limiting block 128 moves up and down in the movable groove 137 and returns to the position facing the locking groove 136. Then the tenon rod 127 leaves the second guide groove 132 along the slope on the side of the second guide groove 132. The self-elastic telescopic rod is compressed, and the limiting block 128 returns to the locking groove 136, and the cutting knife 126 is locked.

[0066] The bottom plate 122 continues to move and comes to the junction of the horizontal straight edge and the vertical straight edge of the first guide groove 131. Then the guide block 138 cooperates with the vertical straight edge of the first guide groove 131 to guide the movable seat 121 and the bottom plate 122 to move away from the non-woven fabric. The non-woven fabric is separated from the bottom plate 122. At this time, the non-woven fabric is manually pulled so that the cut non-woven fabric passes through the dividing knife 134 on the mounting rod 133 to further divide the non-woven fabric. At this time, the temperature of the non-woven fabric is still relatively high. The cutting knife 126 can easily cut the non-woven fabric without generating too much lint. Then, the divided non-woven fabric is wound around the reeling rod 135, and the reeling rod 135 reels the non-woven fabric.

[0067] Then the bottom plate 122 moves to another horizontal straight edge, and then moves to another vertical straight edge, and moves vertically. The bottom plate 122 located above the non-woven fabric moves downward and moves along the slope of the upper push block 118, pushing the upper push block 118 to move. The upper push block 118 drives the disc 116 to rotate through the rocker 117, and the disc 116 drives the dial 115 to rotate. The dial 115 toggles the connecting rod 114 at the top, and the connecting rod 114 rotates, and the knocking block 113 moves away from the knocking rod 111, and the connecting rod 114 rotates. The torsion spring between the connecting rod 114 and the frame 1 is twisted, and the disc 116 continues to rotate. The connecting rod 114 is separated from the dial wheel 115. The torsion spring drives the knocking block 113 to move and collide with the supporting rod 112, and then pushes the knocking rod 111 above to collide with the non-woven fabric. The spring between the knocking rod 111 and the frame 1 is compressed, and the two discs 116 rotate synchronously, but there is an angle difference between the two discs 116. The knocking rod 111 below the non-woven fabric will alternately hit the non-woven fabric with the knocking rod 111 above the non-woven fabric;

[0068] When the knocking block 113 collides with the knocking rod 111, the knocking block 113 hits the rubber block on the top of the supporting rod 112 on the knocking rod 111. The knocking block 113 maintains contact with the supporting rod 112 for a certain period of time, and maintains a certain force to continuously output, so that the supporting rod 112 is compressed, and then the supporting rod 112 pushes the knocking rod 111 to move and extend. Based on the continuous force of the knocking rod 111, the knocking rod 111 collides with the non-woven fabric, causing the non-woven fabric to shake violently, and shaking off the attachments on the non-woven fabric. Although the kinetic energy output by the knocking block 113 will be lost in the process of dry transfer, the retractable supporting rod 112 and the rubber block at the end of the supporting rod 112 can reduce the damage of the knocking block 113 and the knocking rod 111 during the collision, extend the adaptability life of the knocking block 113 and the knocking rod 111, and at the same time, the rubber block can greatly reduce the noise generated during the collision.

[0069] When the knocking rod 111 knocks the non-woven fabric, the non-woven fabric shakes violently, shaking off the attachments on it. At the same time, the blower blows disinfectant gas into the interior of the frame 1, and the disinfectant gas blows the non-woven fabric to blow off the attachments on the non-woven fabric. At the same time, the vacuum cleaner receives the disinfectant gas blown through the non-woven fabric through the suction port 14 and sucks away the used disinfectant gas and the attachments therein.

[0070] When the connecting rod structure composed of the disc 116, rocker 117 and upper push block 118 above the non-woven fabric reaches the dead point, the connecting rod structure composed of the disc 116, rocker 117 and lower push block 119 below the non-woven fabric has not reached the dead point. The lower disc 116 can continue to rotate, thereby driving the upper disc 116 to rotate, and continue to rotate beyond the dead point of the connecting rod structure. Similarly, when the lower connecting structure reaches the dead point, the upper disc 116 can drive the lower disc 116 to continue rotating.

[0071] Furthermore, the bottom plate 122 in the clamping mechanism located above the non-woven fabric in the above embodiment can be staggered with the bottom plate 122 in the clamping mechanism located below the non-woven fabric, so that the cutting knife 126 in the upper bottom plate 122 and the cutting knife 126 in the lower bottom plate 122 are staggered, and the cutting edges of the cutting knife 126 for cutting the non-woven fabric can be connected, thereby directly realizing the edge trimming of the non-woven fabric, and the step of cutting the non-woven fabric with the dividing knife 134 can be omitted.

[0072] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
