DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0040] Example:

[0041] See also Figure 1-Figure 10 The present invention provides a technical solution: a needling machine for foam board production, comprising a base frame 1, a guide column 3 is fixedly installed on the top of the base frame 1, a telescopic cylinder 4 is fixedly installed on the top of the guide column 3, an extrusion plate 5 is movably installed on the outer side of the guide column 3, the bottom end of the telescopic cylinder 4 is fixedly connected to the extrusion plate 5, a needle hole plate 6 and a supporting oil cylinder 8 are respectively fixedly installed on the base frame 1, a first mounting plate 9 is fixedly installed on the top of the supporting oil cylinder 8, a foam board body 7 is arranged above the needle hole plate 6, a connecting mechanism is arranged inside the first mounting plate 9, and a needle plate 2 is installed through the connecting mechanism, the connecting mechanism facilitates the quick disassembly and installation of the needle plate 2 on the first mounting plate 9, facilitates the rapid repair and replacement of the needle plate 2 if it is damaged, and increases the acupuncture work efficiency of the needle plate 2 on the foam board body 7.

[0042] The telescopic cylinder 4 works to fix the top of the foam board body 7 on the needle plate 6 through the squeezing plate 5. When the needle plate 2 needles the foam board body 7, the squeezing plate 5 prevents the foam board body 7 from moving when the needle plate 2 is working. It also prevents the movement of the foam board body 7, which causes the needle on the needle plate 2 to be damaged, such as tilting.

[0043] In this embodiment, a connecting block 19 and a plug-in column 48 are fixedly installed at the bottom end of the needle plate 2, and the plug-in column 48 extends through the first mounting plate 9. A fixed frame 23 is fixedly installed inside the first mounting plate 9, and a connecting frame 24 and an extension frame 26 are fixedly installed in the fixed frame 23. The connecting block 19 extends into the extension frame 26, and two adjacent extension frames 26 are distributed in the connecting frame 24. A second abutment block 29 is movably installed at the end of the extension frame 26, and the other end of the second abutment block 29 is plugged into the plug-in column 48.

[0044] The plug-in column 48 and the connecting block 19 are both inserted into the top end of the first mounting plate 9. After the connecting block 19 enters the first mounting plate 9, the second abutment block 29 is inserted into the plug-in column 48 through the diagonal support plate 27 and the second sliding block 28, thereby fixing the plug-in column 48 to prevent the plug-in column 48 from moving, thereby achieving quick installation of the needle plate 2.

[0045] In this embodiment, a first sliding block 21 is movably installed in the connecting frame 24, and a sliding groove 31 matching the first sliding block 21 is opened on the inner wall of the connecting frame 24. The top of the first sliding block 21 contacts the connecting block 19, and a diagonal support plate 27 is movably installed on the bottom of the first sliding block 21. A second sliding block 28 is movably installed in the expansion frame 26, and the second sliding block 28 is movably connected to the other end of the diagonal support plate 27. A first compression spring 30 is fixedly installed on one side of the second sliding block 28, and the other end of the first compression spring 30 is fixedly connected to the outer wall of the connecting frame 24, and the other side of the second sliding block 28 is fixedly connected to the second abutment block 29.

[0046] After the connecting block 19 enters the first mounting plate 9, it contacts the first sliding block 21. With the action of gravity of the needle plate 2, the connecting block 19 will drive the first sliding block 21 to slide downward in the connecting frame 24. The sliding groove 31 ensures the stability of the first sliding block 21 when sliding. At the same time, when the first sliding block 31 moves downward, the second sliding block 28 will cooperate with the movement to increase the angle between the diagonal support plate 27 and the connecting frame 24. At the same time, the diagonal support plate 27 will drive the second sliding block 28 to slide on the fixed frame 23, so that the first compression spring 30 is stretched. At the same time, the second sliding block 28 will drive the second abutment block 29 to slide toward the outside of the fixed frame 23, and the other end of the second abutment block 29 will extend into the plug-in column 49, thereby achieving a quick connection between the needle plate 2 and the first mounting plate 9.

[0047] In this embodiment, an adjusting mechanism 18 is provided at the bottom end of the first mounting plate 9, and the adjusting mechanism 18 can prompt the connecting mechanism to quickly remove the needle plate 2 from the first mounting plate 9. The adjusting mechanism 18 includes a second mounting plate 20 and a movable gear column 22. The second mounting plate 20 is fixedly mounted on the bottom end of the first mounting plate 9, and a second telescopic cylinder 35 is fixedly mounted on the side of the second mounting plate 20. A second rotating gear 34 is movably mounted on the end of the second telescopic cylinder 35. A rotating column 32 is movably mounted on the upper part of the second mounting plate 20, and a first rotating gear 33 is movably mounted on the outer side of the rotating column 32, and a second rotating gear 34 is movably mounted on the outer side of the rotating column 32.

[0048] The second telescopic cylinder 35 is provided with a controller. When the needle plate 2 needs to be removed from the first mounting plate 9, the second telescopic cylinder 35 will drive the second rotating gear 34 to move on the rotating column 32 and move it until it contacts the rotating block 16. A sliding bar groove is provided between the second rotating gear 34 and the rotating column 32. The second rotating gear 34 can move laterally on the outer side of the rotating column 32. When the rotating column 32 rotates, the second rotating gear 34 will rotate at the same time, and the end of the second telescopic cylinder 35 is movably connected to the second rotating gear 34. A circular connecting groove is provided on the side of the second rotating gear 34 close to the second telescopic cylinder 35. The second telescopic cylinder 35 is located in the circular connecting groove, so that the second telescopic cylinder 35 can push the second rotating gear 34 to slide on the rotating column 32. At the same time, the second rotating gear 34 will not be restricted by the second telescopic cylinder 35 when rotating.

[0049] The telescopic cylinder works by fixing the upper part of the foam board body on the needle hole plate through the extrusion plate. When the needle plate is acupuncturing the foam board body, the extrusion plate prevents the foam board body from moving when the needle plate is working. It also prevents the movement of the foam board body, which causes the needle on the needle plate to tilt and other damages, thereby ensuring the accuracy of acupuncture and improving product quality.

[0050] In this embodiment, the mobile gear column 22 is meshingly connected with the first rotating gear 33, and the two adjacent mobile gear columns 22 are rotationally symmetrically distributed about the center of the first rotating gear 33, and the adjacent sides of the two adjacent mobile gear columns 22 are fixedly installed with the first abutment block 25, the first abutment block 25 and the second abutment block 29 are located on the same straight line, and the first abutment block 25 and the second abutment block 29 are in contact with each other.

[0051] When the needle plate 2 needs to be removed from the first mounting plate 9, the first rotating gear 33 is driven to rotate by the coordinated rotation of the second rotating gear 34 and the rotating column 32. When the first rotating gear 33 rotates, it will drive the moving gear column 22 to move in the second mounting plate 20 and the inner wall of the bottom end of the first mounting plate 9, and the two adjacent moving gear columns 22 are close to each other. When the moving gear column 22 moves, it will contact the second abutment block 29 through the first abutment block 25, and drive the second abutment block 29 to move to the side of the fixed frame 23, and at the same time, the second abutment block 29 will separate from the plug-in column 48. When the second abutment block 29 moves, it will drive the second sliding block 28 to move toward the side of the connecting frame 24, and the diagonal support plate 27 movably connected to the second sliding block 28 will move, and the angle between the diagonal support plate 27 and the connecting frame 24 will become smaller. Due to the inconvenience of the length of the diagonal support plate 27, the diagonal support plate 27 will drive the first sliding block 21 to move upward in the sliding groove 31 in the connecting frame 24 when it moves, and the connecting block 19 located above the first sliding block 21 will move toward the outside of the first mounting plate 9 at the same time, that is, the needle plate 2 is separated from the first mounting plate 9, so as to achieve the quick release of the needle plate 2.

[0052] After the connecting block 19 enters the first mounting plate 9, the second abutment block 29 will be inserted into the plug-in column 48 through the diagonal support plate 27 and the second sliding block 28, thereby fixing the plug-in column 48 to prevent the plug-in column 48 from moving, thereby ensuring the stability of the needle plate 2 after installation. When the first sliding block 21 slides in the connecting frame 24, the sliding groove 31 ensures the stability of the first sliding block 21 when sliding, thereby enhancing the stability of the entire connecting mechanism.

[0053] In this embodiment, a fixed box 10 is fixedly installed on the top of the base frame 1, and a reciprocating motion mechanism is arranged above the fixed box 10. The top of the reciprocating motion mechanism is movably connected to the bottom end of the first mounting plate 9. When the reciprocating motion mechanism is working, it can drive the needle plate 2 through the pinhole plate 6 through the first mounting plate 9 to periodically puncture the foam board body 7, thereby prompting air to enter the foam board body 7 to perform secondary foaming of butane in the product.

[0054] In this embodiment, the reciprocating motion mechanism includes a first motor 14 and an arc-shaped contact plate 17. A rotating disk 15 is fixedly mounted on the first motor 14. A support column 11 is movably mounted on the side of the rotating disk 15 at a position offset from the center. The top of the support column 11 is movably connected to the bottom end of the first mounting plate 9. A rotating block 16 is fixedly mounted on the outer ring side of the rotating disk 15. The shape of the rotating block 16 is set to be L-shaped. The rotating block 16 is in sliding contact with the arc-shaped contact plate 17. An arc-shaped tooth block plate is fixedly mounted on the outer side of the rotating block 16. The arc-shaped tooth block plate is meshingly connected to the second rotating gear 34.

[0055] The first motor 14 is fixedly installed at the top of the side of the fixed box 10. When the first motor 14 is working, it will drive the rotating disk 15 to rotate. When the rotating disk 15 rotates, it will drive the first mounting plate 9 to move up and down periodically between the base frame 1 through the support column 11. When the rotating disk 15 rotates, it will also drive the rotating block 16 to rotate together. When the rotating block 16 rotates and contacts with the arc contact plate 17, the piston plate 39 in the fixed box 10 will move downward, and the gas or liquid under the piston plate 39 in the fixed box 10 will flow into the inner cavity of the base frame 1 through the connecting pipe 12. When the rotating block 16 does not contact with the arc contact plate 17, the piston plate 39 in the fixed box 10 will move up, and the rotating block 16 will be parallel to and overlap with the support column 11. When the second rotating gear 34 contacts with the rotating block 16, the needle plate 2 can be quickly disassembled.

[0056] When the reciprocating mechanism is working, the first mounting plate 9 can drive the needle plate 2 to periodically puncture the foam plate body 7 through the pinhole plate 6, so as to force air into the foam plate body 7 to perform secondary foaming of butane in the product, thereby improving the production speed and efficiency.

[0057] See also Figure 11-Figure 14 The present invention provides a technical solution: in this embodiment, a piston plate 39 is movably installed in the fixed box 10, and the top end of the piston plate 39 passes through the fixed box 10 and is fixedly connected to the bottom end of the arc contact plate 17. A connecting pipe 12 is fixedly installed through the side wall of the fixed box 10, and the other end of the connecting pipe 12 extends into the base frame 1. An inner cavity is opened in the base frame 1, and a T-shaped fixed block 40 and a fixed rod 42 are fixedly installed in the inner cavity respectively. A first movable block 41 and a second compression spring 45 are movably installed on the outer side of the T-shaped fixed block 40 respectively, and a connecting column 43 is fixedly installed on the top end of the first movable block 41. The top end of the connecting column 43 passes through the T-shaped fixed block 40 and is fixedly installed with a second movable block 44.

[0058] When the rotating block 16 contacts the arc-shaped contact plate 17, the piston plate 39 will move the components in the inner cavity of the base frame through the connecting pipe 12, thereby clamping and releasing the foam board body 7, facilitating the transportation of the foam board body 7, and thus carrying out the next foam board acupuncture work, with simple and efficient operation.

[0059] In this embodiment, a clamping plate 38 and a third compression spring 46 are movably installed on the outer side of the fixed rod 42, the clamping plate 38 is in contact with the foam board body 7, a second inclined panel 47 is fixedly installed on the bottom end of the clamping plate 38, and a first inclined panel 37 is fixedly installed on the top end of the second movable block 44, and the first inclined panel 37 and the second inclined panel 47 are in sliding contact with each other.

[0060] When the rotating block 16 contacts the arc contact plate 17, the support column 11 will move downward at the highest height of the rotating disk 15, that is, the support column 11 will drive the first mounting plate 9 to move downward in the pinhole plate 6 and the foam plate body 7. When the rotating block 16 contacts the arc contact plate 17, the piston plate 39 will move the first movable block 41 in the inner cavity of the base frame 1 upward through the connecting pipe 12. When the first movable block 41 moves, it will drive the second movable block 44 to move upward at the same time through the connecting column 43, and compress the second compression spring 45. When the second movable block 44 moves upward, it will drive the first inclined plate 37 and the second inclined plate 47 The arc contact plate 17 is in direct contact with the foam board body 7, and the clamping plate 38 is driven by the second inclined plate 47 to clamp the foam board body 7, and the third compression spring 46 is squeezed at the same time. When the support column 11 moves to the lowest height with the rotation of the rotating disk 15, the rotating block 16 will be separated from the arc contact plate 17, and the needle plate 2 will also be separated from the foam board body 7 and detached from the pinhole plate 6. The arc contact plate 17 will rise under the release of the elastic force of the second compression spring 45 and the third compression spring 46, and the clamping plate 38 will be separated from the foam board body 7, so as to facilitate the transportation of the foam board body 7 on the pinhole plate 6, so as to carry out the next foam board needling work.

[0061] In this embodiment, a collecting chamber 36 is opened on the side of the base frame 1, and a collecting fan 49 is fixedly installed in the collecting chamber 36. A collecting box 13 is fixedly installed on the side of the base frame 1, and the collecting box 13 is located on the side of the collecting chamber 36. When the needle plate 2 moves to the bottom, the needle plate 2 contacts the collecting chamber 36. The collecting fan 49 will collect the foam impurities remaining on the needle plate 2 to ensure that there are no foam impurities on the needle plate 2, while preventing damage to the needle plate 2 and preventing the needles of the foam plate body 7 from tilting during acupuncture.

[0062] A collecting chamber 36 is provided on the side of the base frame 1, in which a collecting fan is fixedly installed. When the needle plate moves to the bottom, the collecting fan will collect the foam impurities remaining on the needle plate to ensure that there are no foam impurities on the needle plate, prevent damage to the needle plate, and prevent the needles from tilting during acupuncture of the foam plate body, thereby further ensuring product quality.

[0063] The working principle of this embodiment is as follows: after the connecting block 19 enters the first mounting plate 9, it contacts the first sliding block 21. With the action of gravity of the needle plate 2, the connecting block 19 will drive the first sliding block 21 to slide downward in the connecting frame 24. The sliding groove 31 ensures the stability of the first sliding block 21 when sliding. At the same time, when the first sliding block 31 moves downward, the second sliding block 28 will cooperate with the movement to increase the angle between the diagonal support plate 27 and the connecting frame 24. At the same time, the diagonal support plate 27 will drive the second sliding block 28 to slide on the fixed frame 23, so that the first compression spring 30 is stretched. At the same time, the second sliding block 28 will drive the second abutment block 29 to slide toward the outside of the fixed frame 23, and the other end of the second abutment block 29 will extend into the plug-in column 49, thereby achieving a quick connection between the needle plate 2 and the first mounting plate 9.

[0064] The first rotating gear 33 is driven to rotate by the coordinated rotation of the second rotating gear 34 and the rotating column 32. When the first rotating gear 33 rotates, it drives the moving gear column 22 to move in the inner wall of the bottom end of the second mounting plate 20 and the first mounting plate 9, and the two adjacent moving gear columns 22 are close to each other. When the moving gear column 22 moves, it contacts the second abutment block 29 through the first abutment block 25, and drives the second abutment block 29 to move to the side of the fixed frame 23. At the same time, the second abutment block 29 is separated from the plug-in column 48, and the second abutment block 29 is moved. When moving, the second sliding block 28 will be driven to move toward the side of the connecting frame 24, and the diagonal support plate 27 movably connected to the second sliding block 28 will move, and the angle between the diagonal support plate 27 and the connecting frame 24 will become smaller. Due to the inconvenient length of the diagonal support plate 27, the diagonal support plate 27 will drive the first sliding block 21 to move upward in the sliding groove 31 in the connecting frame 24 when moving, and the connecting block 19 located above the first sliding block 21 will move toward the outside of the first mounting plate 9 at the same time, that is, the needle plate 2 is separated from the first mounting plate 9, so as to achieve the quick release of the needle plate 2.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
