Description

Technical Field

[0001] This application relates to the field of sponge processing technology, specifically a sponge cutting device. Background Technology

[0002] Currently, there are more and more oxygen generating devices on the market, and people are using them more and more widely. Because existing oxygen generating devices are noisy when emitting gas during operation, they need to be noise-reducing through sound-absorbing sponges. Most existing sound-absorbing sponges are cylindrical, and the sides of square cylindrical sponges are usually rounded during processing and production.

[0003] In existing sponge processing, the heating wire of the thermal cutting equipment cuts into the square cylindrical sponge from one side and is then rounded by a workbench. However, the waste generated during the cutting process cannot be automatically and completely removed from the cutting area, requiring manual assistance for unloading. If not handled in time, the waste in contact with the heating wire is prone to ignition, posing a safety hazard.

[0004] Therefore, it is necessary to provide a sponge cutting device to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a sponge cutting device that solves the problem that waste materials are prone to ignition at the cutting point.

[0007] The technical solution adopted by this application to solve its technical problem is: a sponge cutting device, including a machine tool, a workbench, a rotating assembly, and a guiding assembly; The top of the machine tool is slidably connected to the bottom of the workbench. The top of the machine tool is provided with a movable groove, and the workbench is located above the movable groove. A grooved strip is fixedly installed on the top of the workbench, and the long side of the grooved strip is parallel to the long side of the movable groove. The rotating assembly includes a mounting frame, a rotary motor, a rotating shaft, and a sleeve. The mounting frame is fixedly installed at the bottom of the workbench, and the rotary motor is fixedly installed at the end of the mounting frame away from the workbench, located within a movable slot. One end of the rotating shaft passes through the workbench and the mounting frame, and is mounted to the workbench and the mounting frame via a bearing. The rotating shaft is located on one side of the slot. One end of the rotating shaft is fixedly connected to the output end of the rotary motor, and the other end of the rotating shaft is engaged with the sleeve. A drive wheel is fixedly installed on the side of the rotating shaft between the sleeve and the workbench. The bottom end of the square sponge to be processed has a mounting groove that mates with the sleeve, forming a square cylindrical sponge, which is easy to fit onto the sleeve. Thus, the sleeve is fitted with the square cylindrical sponge to be processed, and the rotary motor controls the rotation of the sleeve via the rotating shaft, facilitating subsequent cutting processing. The guiding assembly includes a moving strip, a support rod, and a guide plate. The bottom of the moving strip is slidably connected to the groove, the top of the moving strip is fixedly connected to the support rod, and one side of the support rod is fixedly connected to the guide plate. A rack is provided on one side of the top of the moving strip, and the rack can mesh with the drive wheel for transmission. Thus, the rotating shaft drives the drive wheel to rotate, and the drive wheel moves the moving strip by meshing with the rack. When the sleeve rotates 60 degrees, the guide plate moves to fit against the side wall of the square cylindrical sponge, thereby increasing the gap between the subsequent cutting waste and the sample, facilitating rapid heat dissipation of the sponge cutting part, and indirectly reducing the probability of fire at the cutting point.

[0008] Furthermore, the guide plate is an arc-shaped plate; thus, the arc-shaped guide plate will not affect the continuous rotation of the inner square cylindrical sponge, and at the same time, it is convenient for the excess sponge portion after cutting to be discharged along the outer side of the guide plate.

[0009] Furthermore, two slide rails are fixedly installed on the top of the machine tool, and the movable groove is located between the two slide rails, with the long side of the movable groove parallel to the long side of the slide rail; an electric telescopic rod is fixedly installed on the top of the machine tool, located on the side of one of the slide rails away from the movable groove; two sliding seats are provided at the bottom of the machine tool, the two sliding seats are arranged in parallel, and the sliding seats are slidably connected to the slide rails one by one; a connecting seat is provided at the bottom of the machine tool, the connecting seat is located on one side of one of the sliding seats, and the end face of the connecting seat is fixedly connected to the end of the electric telescopic rod; thus, the electric telescopic rod provides pushing and pulling force to the machine tool through the connecting seat, and the machine tool moves along the slide rails through the sliding seats.

[0010] Furthermore, a bracket is fixedly installed on the top of the machine tool, the bracket is located at one end of the movable slot, and a magnetic male connector is fixedly installed at the support end of the bracket; a magnetic female connector is fixedly installed at the end of the moving bar away from the rack; the magnetic male connector and the magnetic female connector are a mating mechanism; thus, when the machine tool is reset, the magnetic female connector at the moving bar engages with the magnetic male connector. When the machine tool proceeds to the next process, the magnetic female connector and the magnetic male connector are in a locked state, the moving bar slides in the slot, so that the rack re-engages with the drive wheel, and at the same time, the guide plate moves away from the square cylindrical sponge, which facilitates the subsequent rotation of the square cylindrical sponge.

[0011] Furthermore, a limiting component is fixedly installed on the top of the workbench. The limiting component is gantry-shaped, with the groove passing through its interior. The crossbeam of the limiting component is L-shaped and faces downwards. The top of the moving bar is slidably connected to the crossbeam of the limiting component, and one side of the rack can fit against the crossbeam of the limiting component. Thus, when the moving bar resets, the rack re-engages with the drive wheel, and the crossbeam of the limiting component abuts against the rack, causing the moving bar to stop moving. This, in turn, causes the magnetic female connector to disengage from the magnetic male connector.

[0012] Furthermore, a pushing assembly is provided on the top of the workbench, the pushing assembly including a support column, a pushing component, and a driven wheel; one end of the support column is fixedly installed on the workbench, and the support column is located on the side of the driving wheel away from the groove; the pushing component and the driven wheel are mounted on the support column through bearings, the pushing component is located on the side of the driven wheel away from the workbench, and a connecting rod is fixedly installed between the pushing component and the driven wheel; The top of the workbench is rotatably connected to intermediate gear one and intermediate gear two. One side of intermediate gear one meshes with the driving gear, the other side of intermediate gear one meshes with intermediate gear two, and the other side of intermediate gear two meshes with the driven gear. Thus, the rotating shaft drives the driving wheel to rotate, which in turn causes the driven wheel to rotate through intermediate gear one and intermediate gear two. The driven wheel controls the rotation of the pushing component through the connecting rod. The pushing component pushes the remaining material after cutting to move from the outside of the guide plate, preventing the remaining material from staying at the cutting point after cutting, and indirectly preventing the remaining material at the cutting point from catching fire.

[0013] Furthermore, the pushing member includes a receiving body and four protrusions. The interior of the receiving body is connected to the support column via a bearing, and the four protrusions are arranged circumferentially. Thus, the scrap material generated during cutting passes between the guide plate and the protrusions. The receiving body drives the protrusions to rotate, and the end of the protrusion away from the receiving body applies a thrust to the triangular part of the scrap material, causing the scrap material to move outward.

[0014] Furthermore, a hot-cutting assembly is fixedly installed on the top of the machine tool. The hot-cutting assembly includes a main frame, an upper support arm, and a lower support arm. One end of the main frame is fixedly connected to the machine tool, and the main frame is located at the end of the movable slot away from the support. One end of the upper support arm and the lower support arm are slidably connected to one side of the main frame, and the upper support arm and the lower support arm are located above the movable slot. A heat insulation plate is slidably connected to one side of the upper support arm and the lower support arm, and a baffle is bolted to one side of the heat insulation plate. An electric heating wire is held between the heat insulation plate and the baffle. Thus, after the electric heating wire is heated, the machine tool controls the square cylindrical sponge to move to the hot-cutting assembly, so that the electric heating wire is in close contact with the middle section of one side of the square cylindrical sponge. The rotating assembly controls the square cylindrical sponge to rotate, so that the electric heating wire rounds the side of the square cylindrical sponge.

[0015] The beneficial effects of this application are as follows: The sponge cutting device provided by this application is equipped with a guide assembly. The rotating shaft drives the drive wheel to rotate, and the drive wheel moves the moving strip by meshing with the rack. When the sleeve rotates 60 degrees, the guide plate moves to fit against the side wall of the square cylindrical sponge, which increases the gap between the subsequent cutting waste and the sample, making it easier for the sponge cutting part to dissipate heat quickly, and indirectly reducing the probability of fire at the cutting point.

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figure 1-12 As shown, this application provides a sponge cutting device for processing cylindrical sound-absorbing sponges, including a machine tool 1, a workbench 2, a rotating assembly 3, and a guiding assembly 5; Reference Figure 1 , Figure 3The top of the machine tool 1 is slidably connected to the bottom of the workbench 2. The top of the machine tool 1 is provided with a movable groove 11, and the workbench 2 is located above the movable groove 11. A groove 24 is fixedly installed on the top of the workbench 2, and the long side of the groove 24 is parallel to the long side of the movable groove 11. Reference Figure 2 The rotating assembly 3 includes a mounting frame 31, a rotary motor 32, a rotating shaft 33, and a sleeve 34. The mounting frame 31 is fixedly installed at the bottom of the workbench 2, and the rotary motor 32 is fixedly installed at the end of the mounting frame 31 away from the workbench 2. The rotary motor 32 is located in the movable slot 11. One end of the rotating shaft 33 passes through the workbench 2 and the mounting frame 31, and is mounted to the workbench 2 and the mounting frame 31 via a bearing. The rotating shaft 33 is located on one side of the groove 24. One end of the rotating shaft 33 is fixedly connected to the output end of the rotary motor 32, and the other end of the rotating shaft 33 is engaged with the sleeve 34. A drive wheel 35 is fixedly installed on the side of the rotating shaft 33 between the sleeve 34 and the workbench 2. The bottom end of the square sponge to be processed is provided with a mounting groove that mates with the sleeve 34, which is used to fit the square sponge onto the sleeve 34. Thus, the sleeve 34 is fitted with the square cylindrical sponge to be processed. The rotary motor 32 controls the rotation of the sleeve 34 through the rotating shaft 33, which facilitates subsequent cutting processing. Reference Figure 2 , Figure 5 The guide assembly 5 includes a moving bar 51, a support rod 52, and a guide plate 53. The bottom of the moving bar 51 is slidably connected to the groove 24, the top of the moving bar 51 is fixedly connected to the support rod 52, and one side of the support rod 52 is fixedly connected to the guide plate 53. A rack 511 is provided on one side of the top of the moving bar 51, and the rack 511 can mesh with the drive wheel 35 for transmission. Thus, the rotating shaft 33 drives the drive wheel 35 to rotate, and the drive wheel 35 moves the moving bar 51 by meshing with the rack 511. When the sleeve 34 rotates 60 degrees, the guide plate 53 moves to fit against the side wall of the square cylindrical sponge, which increases the gap between the subsequent cutting waste and the sample, facilitates rapid heat dissipation of the sponge cutting part, and indirectly reduces the probability of fire at the cutting point.

[0021] Where: Reference Figure 5 The guide plate 53 is an arc-shaped plate; thus, the arc-shaped guide plate 53 will not affect the continuous rotation of the inner square cylindrical sponge, and at the same time, it is convenient for the excess sponge part after cutting to be discharged along the outer side of the guide plate 53.

[0022] Reference Figure 1Two slide rails 12 are fixedly installed on the top of the machine tool 1. A movable groove 11 is located between the two slide rails 12, and the long side of the movable groove 11 is parallel to the long side of the slide rail 12. An electric telescopic rod 13 is fixedly installed on the top of the machine tool 1. The electric telescopic rod 13 is located on the side of one of the slide rails 12 away from the movable groove 11. Two sliding seats 21 are provided at the bottom of the workbench 2. The two sliding seats 21 are arranged in parallel and are slidably connected to the slide rails 12 one by one. A connecting seat 22 is provided at the bottom of the workbench 2. The connecting seat 22 is located on one side of one of the sliding seats 21, and the end face of the connecting seat 22 is fixedly connected to the end of the electric telescopic rod 13. Thus, the electric telescopic rod 13 provides a pushing and pulling force to the workbench 22 through the connecting seat 22, and the workbench 2 moves along the slide rail 12 through the sliding seat 21.

[0023] Reference Figure 1 , Figure 6 A bracket 14 is fixedly installed on the top of the machine tool 1. The bracket 14 is located at one end of the movable groove 11. A magnetic male connector 15 is fixedly installed at the support end of the bracket 14. A magnetic female connector 54 is fixedly installed at the end of the moving bar 51 away from the rack 511. The magnetic male connector 15 and the magnetic female connector 54 are a mating mechanism. Thus, the machine tool 2 is reset, and the magnetic female connector 54 at the moving bar 51 is engaged with the magnetic male connector 15. When the machine tool 2 proceeds to the next process, the magnetic female connector 54 and the magnetic male connector 15 are locked. The moving bar 51 slides in the groove 24, so that the rack 511 re-engages with the drive wheel 35. At the same time, the guide plate 53 moves away from the square cylindrical sponge, which facilitates the subsequent rotation of the square cylindrical sponge.

[0024] Reference Figure 2 , Figure 4 , Figure 9 A limiting member 25 is fixedly installed on the top of the workbench 2. The limiting member 25 is gantry-shaped, and the groove 24 passes through the interior of the limiting member 25. The crossbeam of the limiting member 25 is L-shaped and faces downward. The top of the moving bar 51 is slidably connected to the crossbeam of the limiting member 25, and one side of the rack 511 can fit against the crossbeam of the limiting member 25. Thus, when the moving bar 51 is reset, after the rack 511 re-engages with the drive wheel, the crossbeam of the limiting member 25 abuts against the rack 511, causing the moving bar 51 to stop moving. This causes the magnetic female connector 54 to disengage from the magnetic male connector 15.

[0025] Reference Figure 2 , Figure 7 , Figure 9The top of the workbench 2 is provided with a pushing assembly 6, which includes a support column 61, a pushing member 62, and a driven wheel 63. One end of the support column 61 is fixedly installed with the workbench 2, and the support column 61 is located on the side of the driving wheel 35 away from the groove 24. The pushing member 62 and the driven wheel 63 are mounted on the support column 61 through bearings, and the pushing member 62 is located on the side of the driven wheel 63 away from the workbench 2. A connecting rod 64 is fixedly installed between the pushing member 62 and the driven wheel 63. The top of the workbench 2 is rotatably connected with intermediate gear 1 71 and intermediate gear 2 72. One side of intermediate gear 1 71 meshes with driving gear 35, the other side of intermediate gear 1 71 meshes with intermediate gear 2 72, and the other side of intermediate gear 2 72 meshes with driven gear 63. Thus, the rotating shaft 33 drives the driving wheel 35 to rotate, and through the intermediate gear 1 71 and intermediate gear 2 72, the driven wheel 63 rotates. The driven wheel 63 controls the rotation of the pushing component 62 through the connecting rod 64. The pushing component 62 pushes the remaining material after cutting to move from the outside of the guide plate 53, so as to avoid the remaining material from staying at the cutting point after cutting, and indirectly avoid the remaining material at the cutting point from catching fire.

[0026] Reference Figure 8 The pusher 62 includes a receiving body 621 and four protrusions 622. The interior of the receiving body 621 is connected to the support column 61 via a bearing, and the four protrusions 622 are arranged circumferentially. Thus, the scrap material generated during cutting passes between the guide plate 53 and the protrusions 622. The receiving body 621 drives the protrusions 622 to rotate. The end of the protrusions 622 away from the receiving body 621 applies a thrust to the triangular part of the scrap material, causing the scrap material to move outward.

[0027] Reference Figure 12 A hot-cutting assembly 4 is fixedly installed on the top of the machine tool 1. The hot-cutting assembly 4 includes a main frame 41, an upper support arm 42, and a lower support arm 43. One end of the main frame 41 is fixedly connected to the machine tool 1, and the main frame 41 is located at the end of the movable slot 11 away from the support 14. One end of the upper support arm 42 and the lower support arm 43 are slidably connected to one side of the main frame 41, and the upper support arm 42 and the lower support arm 43 are located above the movable slot 11. One side of the upper support arm 42 and the lower support arm 43 is slidably connected to one side of the main frame 41. A heat insulation plate 441 is installed in a moving connection. A baffle 442 is installed on one side of the heat insulation plate 441 by bolts. An electric heating wire 45 is held between the heat insulation plate 441 and the baffle 442. Thus, after the electric heating wire 45 is heated, the workbench 2 controls the square cylindrical sponge to move to the heat cutting component 4, so that the electric heating wire 45 is in close contact with the middle section of one side of the square cylindrical sponge. The rotating component 3 controls the square cylindrical sponge to rotate, so that the electric heating wire 45 rounds the side of the square cylindrical sponge.

[0028] In summary, the working process is as follows: the square cylindrical sponge is installed on the sleeve 34 while the heating wire 45 heats it; the electric telescopic rod 13 controls the workbench 2 to move towards the hot cutting assembly 4; the positional status of the guide assembly, the pushing assembly, and the square cylindrical sponge on the workbench 2 is referenced. Figure 9 As the workbench 2 continues to move, the heating wire 45 cuts into the middle section of one side of the square tubular sponge; the rotary motor 32 controls the sleeve 34 to rotate through the rotating shaft 33, and the heating wire 45 rounds the square tubular sponge. Reference Figure 10 While the sleeve 34 drives the square cylindrical sponge to rotate, the drive wheel 35 causes the moving bar 51 to control the guide plate 53 to move closer to the square cylindrical sponge through the rack 511. When the square cylindrical sponge rotates sixty degrees, one corner of the square cylindrical sponge close to the guide plate 53 is located on the inner side of the guide plate 53, the rack 511 disengages from the drive wheel 35, and the guide plate 53 no longer moves. While the driving wheel 35 pushes the rack 511, it also causes the driven wheel 63 to rotate through the intermediate gear 1 71 and intermediate gear 2 72. The driven wheel 63 controls the rotation of the pushing component 62 through the connecting rod 64. The pushing component 62 pushes the cut residue to move from the outside of the guide plate 53 (see reference). Figure 11 This prevents leftover material from remaining at the cutting point after cutting, indirectly preventing the leftover material at the cutting point from catching fire; After cutting, the rotary motor 32 stops working and enters an idle state; the electric telescopic rod 13 pushes the workbench 2 to reset, and the magnetic female connector 54 at the moving bar 51 engages with the magnetic male connector 15; the cut sample sponge is removed and replaced with a new square cylindrical sponge; the electric telescopic rod 13 pushes the workbench 2 to move, and because the magnetic female connector 54 and the magnetic male connector 15 are locked, the moving bar 51 slides in the groove 24, causing the rack 511 to re-engage with the drive wheel 35; after one end of the rack 511 abuts against the limit member 25, the moving bar 51 stops moving, and the workbench 2 continues to move, causing the magnetic female connector 54 to disengage from the magnetic male connector 15; when the workbench 2 controls the square cylindrical sponge to reach the cutting position, the drive wheel 35 pushes the rack 511 to move away from the magnetic male connector 15; thus, the guide component 5 is automatically reset after use.
