Description

Technical Field

[0002] A needle punching machine is used to prepare high-performance fiber products by densely punching multi-layer fiber cloth. It repeatedly punctures the fiber web with needles having a triangular or other shaped cross-section and barbs on the edges. When multiple needles puncture the fiber web, the barbs on the needles drive the fibers on the surface and subsurface of the fiber web to move from the plane direction of the fiber web to the vertical direction of the fiber web, causing the fibers to shift up and down. The fibers that shift up and down exert a certain pressure on the fiber web, causing the fibers in the fiber web to come closer and be compressed.

DETAILED DESCRIPTION OF THE INVENTION

[0025] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0026] Embodiment: Refer to Figures 1 - 5, A misaligned needle device for a needle punching machine, comprising: a main beam 1, a driving mechanism 2, a connecting mechanism 3 and a pneumatic feeding module 4. The driving mechanism 2 is installed on the main beam 1. The driving mechanism 2 is arranged on a mounting frame. The driving mechanism 2 is connected to the pneumatic feeding module 4 through the connecting mechanism 3. The top end of the pneumatic feeding module 4 is slidably connected to the main beam 1. The output end of the pneumatic feeding module 4 faces the coiling roller on the mounting frame.

[0027] The principle and beneficial effects of the above solution are as follows:

[0028] The operator fixes the end of the fiber material on the coiling roller and starts the coiling roller to wind the fiber material. During the winding process, the pneumatic feeding module 4 is started to process the fiber material. When the area of the fiber material to be processed is large, the driving mechanism 2 is started. The driving mechanism 2 drives the connecting mechanism 3 to move longitudinally. The connecting mechanism 3 drives the pneumatic feeding module 4 to move longitudinally. At the same time, the pneumatic feeding module 4 processes the material. By setting the driving mechanism 2 to be connected to the connecting mechanism 3 and the connecting mechanism 3 to be connected to the pneumatic feeding module 4, and the driving mechanism 2 drives the connecting mechanism 3 and the pneumatic feeding module 4 to move longitudinally, the pneumatic feeding module 4 can process fiber materials with a large area.

[0029] By setting the pneumatic feeding module 4, the setting of the lifting mechanism in the device is reduced, the cost of device manufacturing is saved, and at the same time, it is convenient to maintain and replace the pneumatic feeding module 4, improving the processing efficiency of the product.

[0030] The driving mechanism 2 includes: a mounting seat 6, a reduction gear 7, a T-shaped screw 8 and a limiting mechanism 9. The top wall of the mounting frame is connected to the top surface of the mounting seat 6. The top surface of the main beam 1 is connected to the bottom surface of the mounting seat 6. The side wall of the mounting seat 6 is connected to the end face of the reduction gear 7. One end of the T-shaped screw 8 is rotatably connected to the output end of the reduction gear 7. The mounting seat 6 is rotatably connected to the T-shaped screw 8. The connecting mechanism 3 is connected to the T-shaped screw 8. The other end of the T-shaped screw 8 is rotatably connected to the limiting mechanism 9. The limiting mechanism 9 is installed on the top surface of the main beam 1. A servo motor is installed on the top surface of the main beam 1. The output end of the servo motor is connected to the input end of the reduction gear 7.

[0031] The principle and beneficial effects of the above solution are as follows:

[0032] When it is necessary to make the connecting mechanism 3 and the pneumatic feeding module 4 move laterally, start the servo motor to rotate forward, driving the reducer 7 to rotate forward. The forward rotation of the reducer 7 drives the T-shaped screw 8 to rotate forward. The forward rotation of the T-shaped screw 8 drives the connecting mechanism 3 to move to the right, and the connecting mechanism 3 drives the pneumatic feeding module 4 to move to the right. Start the servo motor to rotate in reverse, driving the reducer 7 to rotate in reverse. The forward rotation of the reducer 7 drives the T-shaped screw 8 to rotate in reverse. The reverse rotation of the T-shaped screw 8 drives the connecting mechanism 3 to move to the left, and the connecting mechanism 3 drives the pneumatic feeding module 4 to move to the left. By setting the rotation of the T-shaped screw 8 to drive the movement of the connecting mechanism 3 and the pneumatic feeding module 4, the efficiency of the mechanism moving left and right is improved, and the setting of components is reduced.

[0033] The limiting mechanism 9 includes: a base 10 and a pedestal bearing 11. The top surface of the main beam 1 is connected to the bottom surface of the base 10, the top surface of the base 10 is connected to the bottom surface of the pedestal bearing 11, and the pedestal bearing 11 is rotatably connected to the other end of the T-shaped screw 8.

[0034] The principle and beneficial effects of the above solution are as follows:

[0035] Install the base 10 on the top surface of the main beam 1, install the pedestal bearing 11 on the base 10, and the pedestal bearing 11 is rotatably connected to the other end of the T-shaped screw 8. By setting the installation base 10 on the top surface of the main beam 1, the installation base 10 can provide a good fixing effect for the pedestal bearing 11, and at the same time, it is convenient for the installation and disassembly of the pedestal bearing 11.

[0036] A bearing limit block 12 is installed on the side wall where the base 10 and the pedestal bearing 11 are connected, and the bearing limit block 12 is rotatably connected to the T-shaped screw 8.

[0037] The principle and beneficial effects of the above solution are as follows:

[0038] A bearing limit block 12 is installed on the side wall where the base 10 and the pedestal bearing 11 are connected, and the bearing limit block 12 is rotatably connected to the T-shaped screw 8. It can limit the T-shaped screw 8 during its operation, and at the same time prevent the T-shaped screw 8 from moving axially, improving the stability of the T-shaped screw 8 during operation.

[0039] The connecting mechanism 3 includes: a T-nut 13, a moving block 14 and an adjusting component 15. The T-shaped screw 8 is arranged in the through hole of the moving block 14. A T-nut 13 is installed on each end face of the moving block 14. The T-nut 13 is concentric with the through hole. The inner diameter of the T-nut 13 is smaller than the inner diameter of the through hole. The T-nut 13 is threadedly connected to the T-shaped screw 8. Both sides of the moving block 14 are respectively connected to one end of the adjusting component 15, and the bottom end of the adjusting component 15 is installed on the top end of the pneumatic feeding module 4.

[0040] The principle and beneficial effects of the above solution are as follows:

[0041] The T-shaped nut 13 is installed on the moving block 14. The T-shaped nut 13 is threadedly connected to the T-shaped screw rod 8. When the T-shaped screw rod 8 rotates, the T-shaped nut 13 can drive the moving block 14 to move. By setting the T-shaped nut 13, it is avoided to process threads on the moving block 14. When the T-shaped nut 13 is worn out too much, directly replacing the T-shaped nut 13 can complete the repair of the connecting mechanism 3, improving the repair efficiency of the mechanism.

[0042] The adjusting assembly 15 includes: a guide post 16 and a connecting block 17. A bushing is provided on each side of the moving block 14. The bushing is slidably connected to the guide post 16. The bottom end of the guide post 16 is connected to the top surface of the connecting block 17. The bottom surface of the connecting block 17 is connected to the top end of the pneumatic feeding module 4.

[0043] The principle and beneficial effects of the above solution are as follows:

[0044] When the moving block 14 moves, the moving block 14 drives the guide post 16 and the connecting block 17 to move. The movement of the connecting block 17 drives the movement of the pneumatic feeding module 4. By setting the bushing to be slidably connected to the guide post 16, the bottom end of the guide post 16 is connected to the top surface of the connecting block 17, and the bottom surface of the connecting block 17 is connected to the top end of the pneumatic feeding module 4. Among them, the connection between the bottom end of the guide post 16 and the top surface of the connecting block 17 can be in a threaded connection manner or a welding manner, which can improve the connection stability between the mechanisms and the synchronous movement efficiency of the pneumatic feeding module 4 at the same time.

[0045] The pneumatic feeding module 4 includes: a needle beam 18, a slider 19 and a needle punching mechanism 20. A plurality of sliders 19 are slidably connected to the bottom end of the main beam 1. The bottom ends of the slider 19 and the connecting block 17 are both connected to the top surface of the needle beam 18. The needle punching mechanism 20 is installed at the bottom end of the needle beam 18.

[0046] The principle and beneficial effects of the above solution are as follows:

[0047] When the connecting block 17 moves, the movement of the connecting block 17 drives the movement of the needle beam 18. The needle beam 18 drives the slider 19 to slide along the bottom end of the main beam 1. The needle beam 18 slides relative to the main beam 1 through the slider 19, improving the movement efficiency of the needle beam 18; when it is necessary to disassemble the needle beam 18 for maintenance, the connecting block 17 connected to the top surface of the needle beam 18 can be disassembled, and the slider 19 and the needle beam 18 can be removed from the bottom end of the main beam 1, improving the disassembly and installation efficiency of the device.

[0048] The needle punching mechanism 20 includes: a cylinder 21, a mounting plate 22, an L-shaped plate 23 and a needle punching assembly 24. A plurality of L-shaped plates 23 are installed on both sides of the needle beam 18. The side wall of the L-shaped plate 23 is equipped with a cylinder 21. An inverted U-shaped groove is formed between the side wall of the L-shaped plate 23 and the cylinder 21. The output end of the cylinder 21 is connected to the top surface of the needle punching assembly 24. The inverted U-shaped groove is slidably connected to the mounting plate 22. The mounting plate 22 is installed on the top surface of the needle punching assembly 24.

[0049] The principle and beneficial effects of the above solution are as follows:

[0050] The output end of the starting cylinder 21 moves downward. The downward movement of the output end of the cylinder 21 drives the needle punching assembly 24 to process the fiber material. The output end of the cylinder 21 moves upward, and the upward movement of the output end of the cylinder 21 drives the needle punching assembly 24 to end the processing of the fiber material. By installing a plurality of L-shaped plates 23 on both sides of the needle beam 18, the cylinder 21 is installed on the side wall of the L-shaped plate 23. The movement of the output end of the cylinder 21 drives the needle punching assembly 24 to move upward or downward to process the fiber material, reducing the setting of the lifting mechanism and saving the space between the mechanisms at the same time;

[0051] An inverted U-shaped groove is formed between the L-shaped plate 23 and the cylinder 21. The inverted U-shaped groove is slidably connected to the mounting plate 22, which can ensure that the needle punching assembly 24 is accurately guided when moving upward or downward, preventing the needle punching assembly 24 from shifting during the movement;

[0052] At the same time, the top wall of the inverted U-shaped groove can limit the mounting plate 22 to prevent damage to the mechanism caused by excessive movement amplitude of the mounting plate 22.

[0053] The needle punching assembly 24 includes: a U-shaped beam 25, a mesh supporting plate 26 and a needle 27. A U-shaped beam 25 is provided on each side of the needle beam 18. The openings of the two U-shaped beams 25 face each other. The top surface of the U-shaped beam 25 is connected to the output end of the cylinder 21. The bottom end of the mounting plate 22 is connected to the top surface of the open end of the U-shaped beam 25. The mesh supporting plate 26 is installed on the inner wall of the U-shaped beam 25. A baffle is installed at the top end of the mesh supporting plate 26. The top surface of the baffle is in contact and cooperation with the top wall of the U-shaped beam 25. The needle 27 is slidably connected in the mesh hole of the mesh supporting plate 26. The bottom surface of the baffle is connected to the top end of the needle 27 through a return spring.

[0054] The principle and beneficial effects of the above solution are as follows:

[0055] After the output end of the cylinder 21 moves downward, the U-shaped beam 25 drives the wire supporting plate 26 and the baffle to move downward, and the needle 27 contacts the fiber material. Since the wire supporting plate 26 continues to move downward, the return spring at the top of the needle 27 is compressed. After the return spring is compressed, the needle 27 pierces the fiber material thoroughly. After the output end of the cylinder 21 moves upward, the U-shaped beam 25 drives the wire supporting plate 26 and the baffle to move upward, the return spring resets, and the continuous upward movement of the wire supporting plate 26 and the baffle drives the needle 27 to move upward through the return spring and pulls the needle 27 out of the fiber material; by setting the return spring to be connected to the top of the needle 27, and the top of the return spring to be connected to the bottom surface of the baffle, when piercing the fiber material, the needle 27 can be gradually inserted into the fiber material. When pulling the needle 27 out of the fiber material, the needle 27 can be gradually pulled out of the fiber material through the action of the return spring, preventing the needle 27 from breaking when piercing or resetting the fiber material due to the too fast moving speed of the needle 27 relative to the fiber material;

[0056] By opening a plurality of mesh holes in the wire supporting plate 26, and the inner wall of the mesh holes is slidably connected with the needle 27, the accuracy of the movement of the needle 27 is improved;

[0057] By setting two U-shaped beams 25 to fix the wire supporting plate 26 and the baffle, and the top of the U-shaped beam 25 is connected to the output end of the cylinder 21, the installation and disassembly efficiency of the wire supporting plate 26 is improved.

[0058] It further includes: positioning bolts 28. A plurality of positioning bolts 28 are threadedly connected to the top surface of the baffle, and the positioning bolts 28 are threadedly connected to the guiding screw holes opened on the top surface of the U-shaped beam 25.

[0059] The principle and beneficial effects of the above solution are:

[0060] By setting the positioning bolts 28 to be threadedly connected to the guiding screw holes opened on the top surface of the U-shaped beam 25, and the positioning bolts 28 are threadedly connected to the top surface of the baffle, the positioning bolts 28 can limit the baffle to prevent the baffle from vibrating or shifting during work;

[0061] At the same time, the positioning bolts 28 improve the fixing effect between the U-shaped beam 25 and the baffle, and the fixing of the baffle increases the installation stability of the wire supporting plate 26.

[0062] It further includes: a cleaning mechanism 5; the cleaning mechanism 5 includes: a suction hole 29 and a negative pressure hole 30. One end of the suction hole 29 is opened on the inner wall of the mesh hole, one end of the negative pressure hole 30 is opened on the end surface of the wire supporting plate 26, the other end of the negative pressure hole 30 is connected to the other end of the suction hole 29, and one end of a filtering device 31 is inserted into the inner wall of the negative pressure hole 30, and the other end of the filtering device 31 is connected to a suction device.

[0063] The inner diameter of the suction hole 29 is smaller than the inner diameter of the negative pressure hole 30.

[0064] The principle and beneficial effects of the above solution are as follows:

[0065] When the device is working, start the suction device. The suction device sucks the negative pressure hole 30 through the filter device 31. The negative pressure hole 30 sucks the mesh hole through the suction hole 29. After the support mesh plate 26 moves downward, when the needle 27 contacts the fiber material, the needle 27 moves upward along the mesh hole. After the conical bottom side wall of the needle 27 moves to the end of the suction hole 29, the mesh hole communicates with the suction hole 29, and the suction hole 29 communicates with the negative pressure hole 30. Through the suction of the suction device, the residual fibers on the needle 27 can be sucked to prevent the fibers from blocking the mesh hole;

[0066] When the support mesh plate 26 moves upward and the needle 27 is separated from the fiber material, the needle 27 moves downward along the mesh hole. After the cylindrical side wall of the needle 27 moves to the end of the suction hole 29, the suction hole 29 is closed, and the suction of the mesh hole by the suction hole 29 ends;

[0067] By arranging a return spring between the top end of the needle 27 and the bottom surface of the baffle, the return spring provides the power for the needle 27 to return, preventing the conical bottom end of the needle 27 from being unable to return due to the influence of air flow after moving to the end of the suction hole 29, and improving the stability of the device operation;

[0068] By arranging the suction device to connect the filter device 31, the filter device 31 connects the negative pressure hole 30, and the negative pressure hole 30 connects the suction hole 29. During the process of the device cleaning the fibers, the air flowing into from the bottom end of the mesh hole can cool the needle 27, preventing the needle 27 from getting hot due to long-term work, improving the service life of the needle 27, and at the same time preventing the fiber material from being thermally denatured due to the too high temperature of the needle 27, and improving the qualified rate of product processing;

[0069] When the cooled needle 27 punctures the fiber material, due to the decrease in the temperature of the needle 27, it can ensure that the pore diameters of the puncture holes processed on the surface of the fiber material are the same, preventing the pore diameters from expanding due to the thermal expansion of the fiber material caused by the increase in the temperature of the needle 27, and further improving the qualified rate of the product after processing.

[0070] Since the inner diameter of the suction hole 29 is smaller than the inner diameter of the negative pressure hole 30, when the mechanism sucks the fibers, the air flow velocity in the suction hole 29 is greater than the air flow velocity in the negative pressure hole 30, improving the suction efficiency of the mechanism for the fibers; at the same time, during the process of sucking the fibers, some fibers can be broken into smaller fibers to prevent the fibers from blocking the mechanism; since the volume of the fibers decreases during the suction process, it is convenient for the operator to clean the device.

[0071] The filtering device 31 includes: a housing 32, a filter screen 33, a lifting column 34, a vibrating wheel 35, a pressure relief spring 36, and a cover plate 37. One end of a connecting pipe is inserted into the inner wall of the negative pressure hole 30, and the other end of the connecting pipe is installed in the mounting hole on the end face of the housing 32. The filter screen 33 is installed on the inner wall of the housing 32. A pressure relief hole is opened at the top end of the housing 32, and the lifting column 34 is slidably connected in the pressure relief hole. A plurality of air guide grooves are opened on the side wall of the lifting column 34, and the bottom end of the air guide groove is located above the top surface of the housing 32. The mounting ring at the top end of the lifting column 34 is connected to the top surface of the housing 32 through the pressure relief spring 36. The bottom end of the lifting column 34 is rotatably connected to the vibrating wheel 35, and the side wall of the vibrating wheel 35 is in rolling cooperation with the filter screen 33. The second mounting hole on the other end face of the housing 32 is equipped with a second connecting pipe, and the output end of the second connecting pipe is connected to the suction device.

[0072] The principle and beneficial effects of the above solution are as follows:

[0073] When the stylet 27 moves upward in the mesh hole, the fiber is sucked into the connecting pipe through the suction hole 29 and the negative pressure hole 30, and enters the housing 32 through the connecting pipe, and is uniformly collected on the filter screen 33 in the housing 32, improving the protection effect of the mechanism on the suction device and preventing the fiber from entering the suction device and causing damage to it;

[0074] When the stylet 27 moves downward in the mesh hole, the suction hole 29 is closed. Due to the continuous operation of the suction device, the lifting column 34 slidably connected in the pressure relief hole of the housing 32 moves downward under the action of negative pressure, and the pressure relief spring 36 is compressed. The air guide groove on the side wall of the lifting column 34 opens the pressure relief hole, preventing the negative pressure in the housing 32 from being too high and causing damage to the housing; when the suction hole 29 is opened, the lifting column 34 resets under the elastic force of the pressure relief spring 36, and the lifting column 34 closes the pressure relief hole, ensuring that there is enough negative pressure in the suction hole 29 to clean the fiber, and improving the working ability of the device when adapting to various working conditions;

[0075] Due to the upward or downward movement of the lifting column 34 in the pressure relief hole, the vibrating wheel 35 rotatably connected to the bottom end of the lifting column 34 is in rolling cooperation with the filter screen 33. The vibrating wheel 35 vibrates the dust on the filter screen 33 during the rolling process, and the vibrated dust falls onto the cover plate 37 on the bottom wall of the housing 32, preventing the filter screen from being blocked due to long-term operation of the mechanism and reducing the difficulty of cleaning the mechanism;

[0076] When too much dust is collected in the device, the cover plate 37 can be opened at the bottom end of the housing 32 to pour out the dust.

[0077] The baffle includes: an upper plate body 38 and an electrode plate 39. The two sides of the upper plate body 38 are respectively in contact and cooperation with the inner walls of a U-shaped beam 25. The electrode plate 39 is connected below the upper plate body 38. The side wall of the electrode plate 39 is connected to the power supply, and the bottom surface of the electrode plate 39 is in contact and cooperation with the top end of the conductive column 40 at the top end of the stylet 27.

[0078] The principle and beneficial effects of the above solution are as follows:

[0079] When the needle 27 moves upward in the mesh hole, the conductive column 40 at the top of the needle 27 contacts the bottom surface of the electrode plate 39. Since the electrode plate 39 is connected to the power supply, after the conductive column 40 contacts the electrode plate 39, a tip discharge is formed at the conical bottom end of the needle 27, which can eliminate the static electricity in the fiber and prevent some fibers from being electrostatically adsorbed in the mesh hole and unable to be completely collected when the suction hole 29 cleans the mesh hole;

[0080] During the process of eliminating static electricity, after the static electricity of the fiber with static electricity is removed, the fiber is guided by the air flow and collides with the inner wall of the mesh hole or the side wall of the needle 27, causing the fiber to break, further preventing the fiber from blocking the mechanism;

[0081] Due to the elimination of static electricity, while improving the cleanliness inside the mesh hole, it can prevent the fiber from being carried out of the support mesh plate 26 by the needle 27 and falling into the fiber material being processed, improving the cleanliness of the fiber material and reducing the steps for the operator to clean the processed fiber material.

[0082] Although the embodiments of the present invention have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples described here.
