Description

Technical Field

[0001] This application belongs to the technical field of nonwoven fabric needle punching equipment, specifically a nonwoven fabric needle punching device that facilitates needle replacement. Background Technology

[0002] Nonwoven fabric needle punching device is a type of equipment commonly used in the textile, carpet, and car seat industries. It is used to process fiber materials to enhance their strength and thickness, and improve their quality and performance. The nonwoven fabric needle punching device is mainly composed of needles, needle plates, drive devices, rollers and other components. Through the up and down movement of the needles and the support of the needle plates, the fiber materials are needle punched to achieve the interweaving and locking of the fibers.

[0003] Referring to CN221662150U, a nonwoven fabric needle punching device includes a frame, a needle punching mechanism, an unwinding roller, and a winding roller. It also includes an expansion mechanism mounted on the winding roller, comprising several floating support blocks. The expansion mechanism includes a pair of mounting slots symmetrically arranged on the outer peripheral wall of the winding roller. A drive unit is installed between the pair of mounting slots to drive each support block to extend / retract into its corresponding mounting slot. In daily use, by adopting the above technical solution, the nonwoven fabric after needle punching is wound onto the winding roller. The drive unit operates, causing each support block to extend out of its corresponding mounting slot. After winding is completed, the drive unit controls each support block to retract into its mounting slot, allowing the wound nonwoven fabric roll to be easily removed from the winding roller.

[0004] However, the following problems still exist. When the needle breaks during use, or when it is necessary to replace the needle with a different specification, the space between the needle and the base plate is small and usually fixed by multiple bolts, which makes the replacement process dangerous. In addition, multiple bolts need to be removed with tools multiple times, which is inconvenient for replacing the needle. Utility Model Content

[0005] The purpose of this application is to address the problems of existing needle punching machines, such as needle breakage during use or the need to replace needles of different specifications, where the space between the needle and the base plate is small and usually fixed by multiple bolts, making replacement dangerous and requiring multiple tool removals, which is inconvenient for needle replacement. The application provides a non-woven fabric needle punching device that facilitates needle replacement.

[0006] The technical solution adopted in this application is as follows: A non-woven fabric needle punching device that facilitates needle replacement includes a support leg. A housing and a worktable are fixedly connected to the upper surface of the support leg. A support frame is fixedly connected to the upper surface of the worktable. An electric telescopic rod is fixedly connected to the upper surface of the support frame. A needle pressing block is fixedly connected to the bottom end of the electric telescopic rod. A push plate is slidably connected to the side of the needle pressing block. A pushing component is provided on the upper surface of the push plate. A limit block is fixedly connected to the side of the needle pressing block. A rotating rod is rotatably connected to the side of the limit block. A bracket is fixedly sleeved on the surface of the rotating rod. A locking component is provided at the end of the rotating rod away from the limit block. A mounting plate is slidably connected to the lower surface of the needle pressing block. A needle is fixedly connected to the lower surface of the mounting plate.

[0007] Preferably, the pushing component includes a driving cylinder, which is fixedly inserted through the upper surface of the push plate. A threaded rod is threadedly connected to the inner wall of the driving cylinder, and the top end of the threaded rod is fixedly connected to the driving cylinder. The bottom end of the threaded rod is rotatably connected to the upper surface of the limiting block. The user can manually rotate the driving cylinder to drive the threaded rod to rotate. The rotation of the threaded rod pushes the push plate downward through the driving cylinder. Reverse rotation of the driving cylinder drives the threaded rod to rotate in the opposite direction, thereby driving the push plate upward.

[0008] Preferably, the locking component includes a positioning cylinder, the side of the positioning cylinder near the bracket being fixedly connected to the end of the rotating rod away from the bracket, a limiting cylinder being rotatably connected to the surface of the positioning cylinder, the side of the limiting cylinder near the piercing block being fixedly connected to the side of the piercing block, a fixing hole being provided on the upper surface of the positioning cylinder, and an insert rod being fixedly connected to the lower surface of the push plate, the inner wall of the fixing hole being adapted to the surface of the insert rod. When the push plate moves down, it drives the insert rod to move down, and the insert rod moves down through the upper surface of the limiting cylinder and enters the fixing hole. At this time, the positioning cylinder is blocked by the insert rod, preventing the rotating rod from rotating, thereby limiting the positioning cylinder, and the bracket cannot rotate.

[0009] Preferably, the number of brackets is four, and each pair of brackets forms a group. The two groups of brackets are symmetrically arranged on both sides of the piercing block with the vertical line on the front of the piercing block as the axis of symmetry. By setting four brackets, the four corners of the mounting plate can be supported respectively, so that the piercing block can push the needle to pierce the non-woven fabric in a stable manner.

[0010] Preferably, an L-shaped sliding plate is fixedly connected to the lower surface of the mounting plate, and baffles are fixedly connected to the front of the two brackets on the front of the piercing block, with the baffles located on the front of the L-shaped sliding plate. By setting the L-shaped sliding plate, the mounting plate can be stably pushed into the piercing block. After the brackets rotate, the mounting plate is limited to the piercing block by the L-shaped sliding plate. After the brackets rotate, the baffles block the front of the L-shaped sliding plate, preventing the mounting plate from swaying towards the front of the piercing block when the piercing block drives the needle to pierce the nonwoven fabric.

[0011] Preferably, a handle is fixedly connected to the front of the mounting plate, which makes it easy for the user to pull the mounting plate out of the puncture block.

[0012] Preferably, a motor is fixedly connected to the front of the housing, a drive rod is fixedly connected to the output end of the motor, a roller is fixedly sleeved on the surface of the drive rod, a support plate is fixedly connected to the front of the housing, a vertical plate is fixedly connected to the top wall of the inner ring surface of the support plate, and a pressure roller is provided on the lower surface of the vertical plate.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, when the needle needs to be replaced, the rotating push component moves the push plate upward, which in turn moves the insertion rod upward away from the fixing hole to cancel the limit on the positioning cylinder. Then, the bracket is rotated, and the bracket rotates away from the mounting plate. Then, the locking component is de-positioned in sequence. After that, the pull handle is pulled, and the pull handle moves the mounting plate, bringing out the needle. Then, according to the needs, mounting plates of different sizes fixed on the needle are pushed into the puncture block. Then, the bracket is rotated to fit against the lower surface of the mounting plate. At this time, the baffle blocks the front of the L-shaped sliding plate. Then, the push component is rotated in the opposite direction, and the push component pushes the push plate downward. The push plate moves down into the fixing hole to reposition the positioning cylinder, so that the device has the effect of facilitating needle replacement. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Example:

[0022] Reference Figure 2-4 A nonwoven fabric needle-punching device for easy needle replacement includes a support leg 1. A housing 2 and a worktable 7 are fixedly connected to the upper surface of the support leg 1. A support frame 8 is fixedly connected to the upper surface of the worktable 7. An electric telescopic rod 9 is fixedly connected to the upper surface of the support frame 8. A needle-pressing block 10 is fixedly connected to the bottom end of the electric telescopic rod 9. A push plate 12 is slidably connected to the side of the needle-pressing block 10. A pushing component 13 is provided on the upper surface of the push plate 12. A limit block 11 is fixedly connected to the side of the needle-pressing block 10. A rotating rod 23 is rotatably connected to the side of the limit block 11. A bracket 17 is fixedly sleeved on the surface of the rotating rod 23. A locking component 16 is provided at the end of the rotating rod 23 away from the limit block 11. A mounting plate 20 is slidably connected to the lower surface of the needle-pressing block 10. A needle 19 is fixedly connected to the lower surface of the mounting plate 20. When the needle 19 needs to be replaced, the needle 19 is rotated... The pusher 13 moves the push plate 12 upward, which in turn moves the insertion rod 161 upward away from the fixing hole 164, thus removing the limit on the positioning cylinder 162. Then, the bracket 17 is rotated away from the mounting plate 20. Next, the locking component 16 is de-positioned. Then, the handle 21 is pulled, which moves the mounting plate 20 and brings out the needle 19. Then, the mounting plates 20 of different sizes fixed on the needle 19 are pushed into the puncture block 10 as needed. Then, the bracket 17 is rotated to fit against the lower surface of the mounting plate 20. At this time, the baffle 18 blocks the front of the rotating rod 23. Then, the pusher 13 is rotated in the opposite direction, which pushes the push plate 12 downward. The push plate 12 moves down into the fixing hole 164 and repositions the positioning cylinder 162, thus making the device easy to replace the needle 19.

[0023] Reference Figure 1-3The pushing component 13 includes a driving cylinder 131, which is fixedly mounted on the upper surface of the push plate 12. A threaded rod 132 is threadedly connected to the inner wall of the driving cylinder 131. A driving cylinder 133 is fixedly connected to the top end of the threaded rod 132. The bottom end of the threaded rod 132 is rotatably connected to the upper surface of the limiting block 11. The user can manually rotate the driving cylinder 133 to drive the threaded rod 132 to rotate. The rotation of the threaded rod 132 pushes the push plate 12 downward through the driving cylinder 131. Reverse rotation of the driving cylinder 133 drives the threaded rod 132 to rotate in the opposite direction, thereby driving the push plate 12 upward. The locking component 16 includes a positioning cylinder 162. The side of the positioning cylinder 162 closest to the bracket 17 is connected to the rotating component. The end of rod 23 away from bracket 17 is fixedly connected. The surface of positioning cylinder 162 is rotatably connected to limit cylinder 163. The side of limit cylinder 163 near the piercing block 10 is fixedly connected to the side of piercing block 10. The upper surface of positioning cylinder 162 is provided with fixing hole 164. The lower surface of push plate 12 is fixedly connected with insertion rod 161. The inner wall of fixing hole 164 is adapted to the surface of insertion rod 161. When push plate 12 moves down, it drives insertion rod 161 to move down. Insertion rod 161 moves down and passes through the upper surface of limit cylinder 163 and enters fixing hole 164. At this time, positioning cylinder 162 is blocked by insertion rod 161, so rotating rod 23 cannot rotate, thereby limiting positioning cylinder 162. At this time, bracket 17 cannot rotate.

[0024] Reference Figure 2-4 There are four brackets 17, and each pair of brackets 17 forms a group. The two groups of brackets 17 are symmetrically arranged on both sides of the piercing block 10 with the vertical line on the front of the piercing block 10 as the axis of symmetry. By setting four brackets 17, the four corners of the mounting plate 20 can be supported respectively, so that the piercing block 10 can push the needle 19 to pierce the non-woven fabric in a stable manner.

[0025] Reference Figure 1-4 An L-shaped sliding plate 22 is fixedly connected to the lower surface of the mounting plate 20. A baffle 18 is fixedly connected to the front of the two side brackets 17 on the front of the piercing block 10, and the baffle 18 is located on the front of the L-shaped sliding plate 22. By setting the L-shaped sliding plate 22, the mounting plate 20 can be stably pushed into the piercing block 10. After the bracket 17 rotates, the L-shaped sliding plate 22 limits the mounting plate 20 in the piercing block 10. After the bracket 17 rotates, the baffle 18 blocks the front of the L-shaped sliding plate 22, preventing the mounting plate 20 from swaying in front of the piercing block 10 when the piercing block 10 drives the needle 19 to pierce the non-woven fabric. A pull handle 21 is fixedly connected to the front of the mounting plate 20. By setting the pull handle 21, it is easy for the user to pull the mounting plate 20 out of the piercing block 10.

[0026] Reference Figure 1-2A motor 3 is fixedly connected to the front of the housing 2. A drive rod 15 is fixedly connected to the output end of the motor 3. A roller 14 is fixedly sleeved on the surface of the drive rod 15. A support plate 4 is fixedly connected to the front of the housing 2. A vertical plate 5 is fixedly connected to the top wall of the inner ring surface of the support plate 4. A pressure roller 6 is provided on the lower surface of the vertical plate 5.

[0027] The implementation principle of the nonwoven needle-punching device embodiment of this application, which facilitates needle replacement, is as follows: When the needle 19 needs to be replaced, the rotating push component 13 drives the push plate 12 to move upward. The upward movement of the push plate 12 drives the insertion rod 161 to move upward away from the fixing hole 164, thus canceling the limitation on the positioning cylinder 162. Then, the bracket 17 is rotated, and the bracket 17 rotates away from the mounting plate 20. Then, the locking component 16 is sequentially de-positioned. After that, the pull handle 21 is pulled, and the pull handle 21 moves the mounting plate 20, bringing out the needle 19. Then, according to the needs, different sizes of mounting plates 20 fixed on the needle 19 are pushed into the puncture block 10. Then, the bracket 17 is rotated to fit against the lower surface of the mounting plate 20. At this time, the baffle 18 blocks the front of the L-shaped sliding plate 22. Then, the pushing component 13 is rotated in the opposite direction, and the pushing component 13 pushes the push plate 12 downward. The push plate 12 moves down into the fixing hole 164 and repositions the positioning cylinder 162, thus making the device easy to replace the needle 19.
