[0001] The invention relates to cutting technology, in particular to a cutting mechanism for an automobile sound insulation pad. Background Art

[0002] As the automotive market continues to expand, the quality of a car's sound insulation has become a key consideration for consumers. However, traditional cutting heads are not suitable for this process. Traditional fabric cutting heads use a disc-shaped cutting method, which is difficult to process for the diverse shapes of sound insulation pads, requiring a vertical cutting head. Furthermore, the cutting heads require disassembly, replacement, or maintenance during long processing periods. These heads are typically secured with screws, but these screws can easily fall off during disassembly and assembly, causing inconvenience.

[0003] CN214322038U discloses a cutting blade replacement structure for a cutting device, wherein the cutting blade body is fixed by a rotating shaft driving a traction rope. The structure is inconvenient to install and relatively complicated. Summary of the Invention

[0004] In order to solve the defects of the above-mentioned prior art, the present invention proposes a cutting mechanism for an automobile sound insulation pad.

[0005] The technical solution of the present invention is achieved as follows:

[0006] A cutting mechanism for automobile sound insulation pads, characterized by comprising:

[0007] A conveyor platform,

[0008] A fixed frame is provided on the conveying platform, and a cylinder is provided on the fixed frame. The lower end of the cylinder passes through the fixed frame and is placed between the fixed frame and the conveying platform. A mounting plate is provided at the lower end of the cylinder, and a motor is provided at the lower end of the mounting plate. The lower end of the motor has a connecting plate, and both ends of the connecting plate are provided with fixing components.

[0009] The cutter head is installed at the lower end of the connecting plate, and the two ends of the cutter head have fixing columns, and the cutter head is connected to the fixing component through the fixing columns, wherein

[0010] The fixing assembly comprises a retaining seat, an elastic member, a movable member and rotating members symmetrically arranged at both ends of the elastic member.

[0011] The retaining seat has an installation chamber in the middle and movable openings connected to the installation chamber at both ends. The elastic member is arranged in the installation chamber. The rotating member is installed in the movable opening through a rotating shaft. The movable member has a through opening in the middle. The movable member is sleeved on the retaining seat through the through opening. The retaining seat has a retaining column, and a spring is sleeved on the retaining column. The movable member has a retaining hole that cooperates with the retaining column, and the retaining column has a nut. The nut is located at the lower end of the movable member. The elastic member has a threaded hole in the middle, and the fixed column has a threaded portion that cooperates with the threaded hole.

[0012] In the present invention, both sides of the elastic member have an inwardly recessed through opening.

[0013] In the present invention, the rotating member comprises a protruding portion extending into the installation chamber and a rotating portion extending downward, the protruding portion is provided with a first guiding inclined surface, and the elastic member is provided with an arcuate portion cooperating with the first guiding inclined surface.

[0014] In the present invention, the protrusion has a strip-shaped hole, and the rotating shaft is arranged in the strip-shaped hole.

[0015] In the present invention, the rotating portion has a second guiding inclined surface.

[0016] In the present invention, the movable part has a symmetrically arranged triangular portion and a blocking portion, a movable area for placing the rotating portion is reserved between the triangular portion and the blocking portion, and the triangular portion has a third guide inclined surface that cooperates with the second guide inclined surface.

[0017] In the present invention, the thickness of the rotating portion is smaller than the width of the active area.

[0018] In the present invention, the rotating member further has a deformation portion extending upward, and the upper end of the movable opening has a fourth guiding inclined surface cooperating with the deformation portion.

[0019] The automotive sound insulation mat cutting mechanism of the present invention has the following advantages: it utilizes an insert-type installation and a push-type removal. To install the cutter head, the elastic member is simply inserted into the installation chamber. To remove it, the movable member is pushed upward, causing the rotating member to also move upward. When the rotating member is blocked by the fourth guide slope, it rotates counterclockwise about the axis. Pulling the cutter head downward releases the elastic member from the installation chamber. This eliminates the need for additional installation tools and facilitates assembly and disassembly, improving replacement efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation Method

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] like Figures 1 to 11 As shown, the automotive sound insulation pad cutting mechanism of the present invention comprises a conveyor platform 1, a fixed frame 2, and a fixed assembly 3. The conveyor platform 1 is used to transport the fabric to be cut to the lower end of the fixed frame 2. A cylinder 4 at the upper end of the fixed frame 2 then drives a motor 5 downward. This rotation of the motor 5 then drives a cutter head 6 to cut the sound insulation pad material into various shapes. A horizontally mounted movable assembly can be added to the fixed frame 2. The movable assembly can be driven by a motor to rotate a screw rod, thereby repositioning the cylinder.

[0034] Mounting frame 2 is mounted on conveyor platform 1. Cylinder 4 is mounted on mounting frame 2, with the lower end of cylinder 4 extending through mounting frame 2 and positioned between the two platforms. A mounting plate 7 is located below cylinder 4, which in turn houses a motor 5. A connecting plate 8 is located below motor 5, with fixing assemblies 3 located at each end of connecting plate 8. Cylinder 4 drives motor 5 up and down, which in turn drives cutter head 6 to rotate to various angles. Fixing assembly 3 facilitates the attachment of cutter head 6 to the lower end of connecting plate 8, utilizing a plug-in mounting mechanism.

[0035] The cutter head 6 is installed at the lower end of the connecting plate 8 . There are fixing columns 9 at both ends of the cutter head 6 . The cutter head 6 is connected to the fixing assembly 3 through the fixing columns 9 .

[0036] The fixing assembly 3 includes a retaining seat 10, an elastic member 11, a movable member 12, and rotating members 13 symmetrically arranged at both ends of the elastic member 11. The retaining seat 10 is connected to the connecting plate 8, and the elastic member 11 is arranged in the middle of the retaining seat 10. The rotating member 13 is used to clamp and fix the elastic member 11, keeping the elastic member 11 in place. The movable member 12 is used to rotate the rotating member 13 about the rotating shaft 14, so that the rotating member 13 no longer supports the elastic member 11, facilitating the removal of the elastic member 11 from the installation chamber 15.

[0037] The elastic member 11 and the rotating member 13 are made of rubber material, so that they have a certain elasticity and can be deformed under force during installation.

[0038] The retaining seat 10 has a central mounting chamber 15 and two ends with movable openings 16 communicating with the mounting chamber 15. The elastic member 11 is disposed in the mounting chamber 15. The rotating member 13 is mounted in the movable opening 16 via a rotating shaft 14. The movable member 12 has a central opening 17 through which the movable member 12 is sleeved onto the retaining seat 10.

[0039] The retaining seat 10 has a retaining post 18 with a spring 19 sleeved thereon. The movable member 12 has a retaining hole 20 that cooperates with the retaining post 18. The retaining post 18 has a nut 21 that is threadedly connected to the retaining post 18 and is located at the lower end of the movable member 12. Since the nut 21 is arranged on the retaining post 18, the nut 21 can be rotated to move the nut 21 on the retaining post 18, thereby changing the position of the movable member 12 on the retaining post 18.

[0040] When the movable member 12 is pushed upward, the movable member 12 can compress the spring 19 upward, causing the spring 19 to shorten. At the same time, the position of the movable member 12 can be moved upward, so that the movable member 12 pushes the rotating member 13 to rotate the moving angle.

[0041] The elastic member 11 has a threaded hole 22 in the middle, and the fixing post 9 has a threaded portion 23 that matches the threaded hole 22. The elastic member 11 is installed on the fixing post 9 by threading, and then the cutter head 6 and the elastic member 11 are inserted into the fixing assembly 3 together.

[0042] The elastic member 11 has an inwardly recessed through opening 43 on both sides. The upper end of the through opening 43 forms an upper contact surface 24 , and the lower end forms a lower contact surface 25 .

[0043] The rotating member 13 comprises a protruding portion 26 extending into the installation chamber 15 and a rotating portion 27 extending downward. The protruding portion 26 has a first guiding inclined surface 28 , and the elastic member 11 has an arcuate portion 29 cooperating with the first guiding inclined surface 28 .

[0044] A support surface 30 is formed at the upper end of the protrusion 26, and a placement surface 31 is formed at the lower end. A lifting surface 32 is formed in the movable opening 16, and the lifting surface 32 contacts the placement surface 31. Furthermore, the support surface 30 contacts the upper contact surface 24 in the through opening 43, so that the upper contact surface 24 is placed on the support surface 30, thereby supporting the entire elastic member 11.

[0045] When the elastic member 11 is inserted, the arcuate portion 29 first contacts the first guide slope 28, pushing the first guide slope 28 upward through the arcuate portion 29. After the rotating member 13 is blocked by the fourth guide slope 33, the arcuate portion 29 disengages from the first guide slope 28, allowing the elastic member 11 to continue to move upward. After this movement, the protrusion 26 can enter the through-hole 43. At this time, the upper end of the elastic member 11 is in a slightly compressed state, keeping the elastic member 11 clamped by the top surface of the installation chamber 15 and the support surface 30 on the protrusion 26, so that its position is fixed.

[0046] In addition, the protrusion 26 has a first side surface 34 , and the through hole 43 has a second side surface 35 that matches the first side surface 34 . After the elastic member 11 is installed, the first side surface 34 and the second side surface 35 contact each other to keep the elastic member 11 in place.

[0047] The raised portion 26 has a strip hole 36 in which the rotating shaft 14 is disposed. The length of the strip hole 36 is three times the diameter of the rotating shaft 14. When the rotating shaft 14 is stationary, the rotating member 13 can be forced to move up and down, and can be pushed by the movable member 12. The lower end of the rotating member 13 can be pushed by the movable member 12, so that it rotates around the rotating shaft 14 at a certain angle, facilitating the removal of the elastic member 11.

[0048] The rotating portion 27 has a second guide slope 37. The movable member 12 has a symmetrically arranged triangular portion 38 and a blocking portion 39. A movable area 40 for the rotating portion 27 is left between the triangular portion 38 and the blocking portion 39. The triangular portion 38 has a third guide slope 41 that mates with the second guide slope 37. The thickness of the rotating portion 27 is less than the width of the movable area 40.

[0049] The rotating member 13 also has an upwardly extending deformable portion 42. The upper end of the movable opening 16 has a fourth guide slope 33 that mates with the deformable portion 42. When the third guide slope 41 pushes the second guide slope 37 to move, the rotating member 13 can rotate about the rotation axis 14. Because the thickness of the rotating portion 27 is smaller than the width of the movable area 40, the rotating portion 27 can rotate within the movable area 40. After the rotation reaches the desired angle, it is blocked by the blocking portion 39.

[0050] When the rotating member 13 is pushed upward, the deformable portion 42 contacts the fourth guide slope 33. Further upward movement causes the deformable portion 42 to deform, causing the entire rotating member 13 to rotate counterclockwise. At this point, pulling the cutter head 6 downward disengages the through-hole 43 of the elastic member 11 from the protrusion 26.

[0051] During installation, first place the symmetrically arranged rotating member 13 into the movable opening 16, then insert the rotating shaft 14 into the corresponding position, keeping the rotating member 13 hinged to the retaining seat 10. Then, install the spring 19 onto the retaining post 18, and then install the movable member 12 onto the retaining post 18 and the retaining seat 10, securing the position of the movable member 12 with the nut 21. The elastic member 11 is connected to the threaded portion 23 of the fixed post 9 through the threaded hole 22.

[0052] When installing the cutter head 6, the elastic member 11 can be directly inserted into the installation chamber 15. When disassembling, the movable member 12 is pushed upward, and then the rotating member 13 is also moved upward. When the rotating member 13 is blocked by the fourth guide slope 33, the rotating member 13 will rotate counterclockwise around the rotating shaft 14. When the cutter head 6 is pulled downward, the elastic member 11 can be separated from the installation chamber 15.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
