Description

Technical Field

[0001] This application relates to the field of die-cutting equipment, and more particularly to a sound-absorbing cotton die-cutting equipment. Background Art

[0002] Using sound-absorbing and sound-insulating materials for sound insulation and noise reduction is a common means of controlling noise pollution. As one of the sound-absorbing and sound-insulating materials, sound-absorbing cotton is widely used. The shapes of sound-absorbing cotton products are diverse, mainly adjusted according to different application scenarios of the sound-absorbing cotton.

[0003] Usually, a die-cutting equipment is used to punch and cut the sound-absorbing cotton, and a specified shape is cut out by a die. In the die-cutting equipment, a pressing mechanism composed of a bottom plate and a top plate is usually provided. The tool is usually arranged on the bottom end surface of the top plate, and the top plate is driven to press down by a cylinder. After the top plate and the bottom plate are in stamping contact, the single-piece sound-absorbing cotton placed between the top plate and the bottom plate will be cut out into a specified shape by the die on the top plate. The die is usually arranged on the bottom end surface of the top plate. When the die needs to be disassembled and replaced, it is necessary for the operator to reach into the space between the top plate and the bottom plate by hand to remove the die. The whole disassembly and replacement operation is inconvenient, so it needs to be improved. Utility Model Content

[0004] In order to improve the problem of inconvenient operation when removing the die, this application provides a sound-absorbing cotton die-cutting equipment.

[0005] A sound-absorbing cotton die-cutting equipment provided by this application adopts the following technical solutions:

[0006] A sound-absorbing cotton die-cutting equipment includes a working frame, a pressing mechanism is arranged on the working frame, a bottom plate for receiving the sound-absorbing cotton is slidably connected to the working frame, a tool is arranged on the bottom plate, the bottom plate can move to directly below the pressing mechanism, and the pressing mechanism is used to press the sound-absorbing cotton on the bottom plate so that the tool cuts the sound-absorbing cotton.

[0007] By adopting the above technical solutions, during operation, first, the bottom plate is pulled out from directly below the pressing mechanism, then the sound-absorbing cotton is placed on the tool, and then the bottom plate is moved back to directly below the pressing mechanism. At this time, the pressing mechanism is started to press the sound-absorbing cotton on the bottom plate. During this process, the tool moves upward relative to the sound-absorbing cotton in the vertical direction, thereby realizing the cutting of the sound-absorbing cotton. When the tool needs to be disassembled and replaced, the bottom plate is directly moved to drive the tool out of the area below the pressing mechanism, so that the tool is exposed upward. The operator can directly observe the tool and the operation is more convenient, so that the operator can directly disassemble the tool.

[0008] Optionally, the pressing mechanism includes a cylinder and a top plate. The cylinder is arranged on the working frame. The top plate is located above the bottom plate and is parallel to the bottom plate. The top plate is fixed to the output end of the cylinder, and the cylinder is used to drive the top plate to move up and down.

[0009] By adopting the above technical solution, when the sound-absorbing cotton is placed on the cutting tool and moves to directly below the top plate driven by the bottom plate, the cylinder is started to drive the top plate to move downwards, so that the top plate abuts against the sound-absorbing cotton. Then the top plate continues to move to press the sound-absorbing cotton, so that the cutting tool continuously embeds into the sound-absorbing cotton from the bottom of the sound-absorbing cotton until the cutting tool completely penetrates the sound-absorbing cotton, realizing the cutting of the sound-absorbing cotton.

[0010] Optionally, a guide rod is fixed on the working frame. The guide rod is arranged vertically and penetrates through the top plate, and the top plate can move on the guide rod.

[0011] By adopting the above technical solution, when the cylinder drives the top plate to move, the top plate slides on the guide rod. The guide rod plays a guiding role, enabling the top plate to move only in the vertical direction, improving the stability of the movement of the top plate, making the moving distance of each part where the sound-absorbing cotton abuts against the cutting tool the same, and preventing the situation that the part where the sound-absorbing cotton abuts against the cutting tool is not cut in place, thus improving the cutting accuracy of the sound-absorbing cotton.

[0012] Optionally, an installation groove is formed on the top wall of the bottom plate, and an installation plate is adaptively inserted into the installation groove. The cutting tool is fixed on the top wall of the installation plate.

[0013] By adopting the above technical solution, when it is necessary to change the shape of the cut sound-absorbing cotton, the installation plate originally connected to the cutting tool is pulled out from the installation groove to realize the disassembly of the original cutting tool on the bottom plate. Then the installation plate provided with the cutting tool of the specified shape is placed into the installation groove to realize the installation of the new cutting tool on the installation plate on the bottom plate, so as to achieve the effect of cutting different sound-absorbing cotton products.

[0014] Optionally, a receiving groove is formed on the top wall of the installation plate.

[0015] By adopting the above technical solution, when it is necessary to take out the installation plate from the installation groove, the operator can reach into the receiving groove and apply force to the inner wall of the receiving groove, so as to facilitate taking out the installation plate from the installation groove.

[0016] Optionally, a slide rail is fixed on the working frame, and a slider is fixed on the bottom wall of the bottom plate. The slider is sleeved on the slide rail and can move on the slide rail.

[0017] By adopting the above technical solution, when moving the bottom plate, the slider moves on the slide rail, and the side wall of the slide rail abuts against the inner wall of the slider, playing a role in limiting and guiding, so that the bottom plate is not easily offset during movement, improving the stability of the bottom plate movement, ensuring that the bottom plate can still return to directly below the top plate after movement, and further improving the precision of cutting the sound-absorbing cotton, and not easily showing a skew situation.

[0018] Optionally, a placement groove is formed in the side wall of the slider, and an oil-soaked sponge is inserted into the placement groove, and the side wall of the oil-soaked sponge abuts against the side wall of the slide rail.

[0019] By adopting the above technical solution, when the bottom plate moves, the slider moves on the slide rail, and the lubricating oil on the oil-soaked sponge adheres to the slide rail, playing a lubricating role, thereby reducing the friction between the slider and the slide rail, and facilitating the movement of the bottom plate on the slide rail.

[0020] Optionally, a handle is fixed on the side wall of the bottom plate.

[0021] By adopting the above technical solution, the handle provides a force application part for the hand, facilitating the operator to drive the bottom plate to move.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] 1. During work, first pull the bottom plate out from directly below the pressing mechanism, then place the sound-absorbing cotton on the cutter, and then move the bottom plate back to directly below the pressing mechanism. At this time, start the pressing mechanism to press the sound-absorbing cotton on the bottom plate. During this process, the cutter moves upward vertically relative to the sound-absorbing cotton, so as to realize the cutting of the sound-absorbing cotton. When it is necessary to disassemble and replace the cutter, directly move the bottom plate to drive the cutter out of the lower area of the pressing mechanism, so that the cutter is exposed upward, and the operator can directly observe the cutter and the operation is relatively convenient, so as to facilitate the operator to directly disassemble the cutter;

[0024] 2. When the sound-absorbing cotton is placed on the cutter and moves to directly below the top plate driven by the bottom plate, start the air cylinder to drive the top plate to move downward, so that the top plate abuts against the sound-absorbing cotton, and then the top plate continues to move to press the sound-absorbing cotton, so that the cutter continuously embeds into the sound-absorbing cotton from the bottom of the sound-absorbing cotton until the cutter completely penetrates the sound-absorbing cotton, realizing the cutting of the sound-absorbing cotton.

Detailed implementation mode

[0029] The following further elaborates on this application in conjunction with the attached Figures 1-3 for a more detailed description of this application.

[0030] The embodiment of this application discloses a sound-absorbing cotton die-cutting device. Refer to Figure 1 and Figure 2 , the sound-absorbing cotton die-cutting device includes a working frame 10, a downward pressing mechanism 20, a bottom plate 30 and a cutting tool 42. The downward pressing mechanism 20 is arranged on the working frame 10. The bottom plate 30 is horizontally arranged on the working frame 10 and is located below the downward pressing mechanism 20. The downward pressing mechanism 20 can move up and down, and the cutting tool 42 is installed on the top wall of the bottom plate 30, and the cutting tool 42 protrudes from the plane of the top wall of the bottom plate 30. During operation, the sound-absorbing cotton is placed on the cutting tool 42, and then the downward pressing mechanism 20 is started to press the sound-absorbing cotton against the bottom plate 30. During this process, the cutting tool 42 moves upward relative to the sound-absorbing cotton in the vertical direction, so as to realize the cutting of the sound-absorbing cotton.

[0031] Refer to Figure 1 and Figure 2 , wherein the downward pressing mechanism 20 includes a cylinder 21 and a top plate 22. The cylinder 21 is installed on the working frame 10 by bolts. The output end of the cylinder 21 is vertically downward. The top plate 22 is horizontally arranged, and the top of the top plate 22 is fixed to the output end of the cylinder 21. The cylinder 21 is used to drive the top plate 22 to move up and down. A guide rod 11 is fixed on the working frame 10. The guide rod 11 is arranged in the vertical direction and passes through the top plate 22. The top plate 22 can move on the guide rod 11.

[0032] After the sound-absorbing cotton is placed on the cutting tool 42, the cylinder 21 is started to drive the top plate 22 to move downward along the guide rod 11 in the vertical direction, so that the top plate 22 abuts against the sound-absorbing cotton. Then the top plate 22 continues to move to press the sound-absorbing cotton, so that the cutting tool 42 continuously embeds into the sound-absorbing cotton from the bottom of the sound-absorbing cotton until the cutting tool 42 completely penetrates the sound-absorbing cotton, realizing the cutting of the sound-absorbing cotton.

[0033] Refer to Figure 1 and Figure 3, to facilitate the placement of the sound-absorbing cotton on the bottom plate 30, a slide rail 12 is fixed on the working frame 10. The slide rail 12 is arranged horizontally. A slider 50 is fixed on the bottom wall of the bottom plate 30. The slider 50 is sleeved on the slide rail 12 and can move along the length direction of the slide rail 12 on the slide rail 12. In order to reduce the friction force of the slider 50 moving on the slide rail 12, a placement groove 51 is opened on the inner wall of the slider 50, and an oil-soaked sponge 60 is inserted in the placement groove 51. The oil-soaked sponge 60 is filled with lubricating oil. One side of the oil-soaked sponge 60 abuts against the side wall of the slide rail 12. When the bottom plate 30 moves, the slider 50 moves on the slide rail 12, and the lubricating oil on the oil-soaked sponge 60 adheres to the slide rail 12, playing a lubricating role, thereby reducing the friction force between the slider 50 and the slide rail 12, and thus facilitating the movement of the bottom plate 30 on the slide rail 12.

[0034] Refer to Figure 1 and Figure 2 , a handle 32 is fixed on the side wall of the bottom plate 30. During operation, an operator applies force to the handle 32, first pulls the bottom plate 30 out from directly below the pressing mechanism 20, then places the sound-absorbing cotton on the cutting tool 42, and then moves the bottom plate 30 back to directly below the pressing mechanism 20, facilitating the placement of the sound-absorbing cotton.

[0035] Refer to Figure 1 , when different-shaped sound-absorbing cotton products need to be prepared, the cutting tool 42 needs to be replaced. To facilitate the removal of the cutting tool 42, a mounting plate 40 is fixed at the bottom of the cutting tool 42. A mounting groove 31 is opened on the top wall of the bottom plate 30. The mounting plate 40 is adaptively inserted into the mounting groove 31, and a long strip-shaped receiving groove 41 is opened on the top wall of the mounting plate 40.

[0036] When the shape of the sound-absorbing cotton to be cut needs to be changed, an operator can reach into the receiving groove 41 and apply force to the inner wall of the receiving groove 41, so as to facilitate pulling out the mounting plate 40 originally connected to the cutting tool 42 from the mounting groove 31. The original cutting tool 42 is disassembled from the bottom plate 30. Then, the mounting plate 40 provided with the cutting tool 42 of the specified shape is placed into the mounting groove 31, and the mounting plate 40 of the new cutting tool 42 on the bottom plate 30 is realized, so as to achieve the effect of cutting out different sound-absorbing cotton products.

[0037] The implementation principle of a sound-absorbing cotton die-cutting device according to an embodiment of the present application is as follows: During operation, first, the bottom plate 30 is withdrawn from directly below the downward pressing mechanism 20, and then the sound-absorbing cotton is placed on the cutting tool 42. Subsequently, the bottom plate 30 is moved back to directly below the downward pressing mechanism 20. At this time, the downward pressing mechanism 20 is started to press the sound-absorbing cotton against the bottom plate 30. During this process, the cutting tool 42 moves upward vertically relative to the sound-absorbing cotton, thereby realizing the cutting of the sound-absorbing cotton. When it is necessary to disassemble and replace the cutting tool 42, the bottom plate 30 is directly moved to drive the cutting tool 42 out of the lower area of the downward pressing mechanism 20, so that the cutting tool 42 is exposed upward. The operator can directly observe the cutting tool 42, and the operation is relatively convenient, thus facilitating the operator to directly disassemble the cutting tool 42.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
