Description

Technical Field

[0001] This invention relates to the field of electric hot wire cutting machine technology, and more specifically to a multi-angle hot wire defoaming machine for processing semi-finished sponge products. Background Technology

[0002] A hot wire foam cutter, also known as an electric hot wire cutter, is a machine that uses an electric hot wire to achieve the cutting purpose. Hot wire cutters are mainly used for cutting foam sponges, filter screens, synthetic fiber fabrics, woven bags, etc. They offer fast cutting speeds and prevent fraying. In the processing of sponge products, hot wire cutters are needed to cut large areas of semi-finished sponge products into smaller pieces.

[0003] Existing hot wire foam descaling machines can only cut sponges at a single angle, and cannot cut at multiple angles according to the specific shape of the sponge product, which is inconvenient for users. In addition, during the process of cutting sponges, the hot wire foam descaling machine will produce small sponge debris. This debris will adhere to the surface of the hot wire foam descaling machine. In order not to affect the subsequent cutting of sponges, the debris adhering to the surface of the hot wire foam descaling machine needs to be cleaned. Manually cleaning the debris from the surface of the hot wire foam descaling machine is time-consuming and labor-intensive, increasing the labor intensity and hindering the improvement of the efficiency of hot wire foam descaling machine in cutting sponges. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-angle hot wire defoaming machine for processing semi-finished sponge products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-angle hot wire defoaming machine for processing semi-finished sponge products includes a processing table. Two columns are installed on one outer wall of the processing table, and a movable frame is set between the two columns. The two columns are equipped with a drive mechanism for moving the movable frame up and down. A rotating rod is rotatably installed on the side of the movable frame closer to the processing table, and a mounting frame is connected to the side of the rotating rod away from the movable frame through a telescopic mechanism. A rectangular groove adapted to the mounting frame is opened at the center of the top of the processing table. Through slots are opened at both ends of the mounting frame near the processing table. The hot wire body is inserted through both through slots. The two through slots are equipped with a fixing mechanism for fixing the two ends of the hot wire body. A cleaning mechanism for cleaning the surface of the hot wire body is installed inside the mounting frame.

[0007] Optionally, the drive mechanism includes a first groove formed on one side of two columns that are close to each other. A drive screw and a slide rod are respectively installed inside the two first grooves, and the two ends of the moving frame are respectively engaged with the outer walls of the drive screw and the slide rod.

[0008] Optionally, a drive motor is installed on the outer wall of the movable frame away from the processing table. The output end of the drive motor is connected to the rotating part of the rotating rod. Multiple telescopic limit rods are installed on the side of the movable frame near the rotating rod. Two limit holes that are adapted to the telescopic ends of the telescopic limit rods are opened on the side of the rotating rod near the movable frame.

[0009] Optionally, the telescopic mechanism includes a second groove on the side of the rotating rod away from the movable frame, a first double-ended screw is rotatably mounted inside the second groove, and two movable blocks are symmetrically mounted on the outer wall of the first double-ended screw.

[0010] Optionally, connecting rods are rotatably mounted on the ends of the two movable blocks away from the first double-ended screw, and the ends of the two connecting rods away from the movable blocks are hinged to one side of the outer wall of the mounting frame.

[0011] Optionally, the fixing mechanism includes screws rotatably mounted at both ends of the mounting bracket, one end of each screw extending into the through groove and connected to a fixing plate, and the other end of each screw connected to a rotating handle.

[0012] Optionally, the cleaning mechanism includes a first slide groove opened on the outer wall of one side of the mounting frame, a first slider installed inside the first slide groove, an electric telescopic rod installed at the end of the first slider away from the first slide groove, and a movable frame connected to the telescopic end of the electric telescopic rod.

[0013] Optionally, a third groove is provided on one inner wall of the movable frame, and a second double-ended screw is installed inside the third groove. Two clamping plates are symmetrically installed on the outer wall of the second double-ended screw, and a cleaning pad is installed on the outer wall of the side of the two clamping plates that are close to each other.

[0014] Optionally, rotating blocks are rotatably mounted on both outer walls of the movable frame, and multiple dust suction ports are opened on one outer wall of each of the two rotating blocks.

[0015] Optionally, the movable frame has two second sliding grooves on the outer walls of both sides near the two rotating blocks. A second slider is installed inside each of the two second sliding grooves. The ends of the two adjacent second sliders away from the second sliding grooves are connected to a mounting base. A protective plate is rotatably installed inside each of the two mounting bases.

[0016] The beneficial effects of this invention are:

[0017] 1. In this invention, the drive motor can drive the rotating rod and mounting frame to rotate, which can drive the hot wire body to cut the sponge on the top of the processing table in both horizontal and vertical directions. Furthermore, the electric telescopic rod and the moving frame can drive the hot wire body to deform, which is convenient for cutting some sponges that need to be processed into bevels, thereby achieving the effect of cutting sponges from multiple angles and improving the overall applicability of the device.

[0018] 2. In this invention, during the process of the hot wire body cutting the sponge, odors and dust will be generated at the contact point between the hot wire body and the sponge. By using the set rotating block and the dust suction port, and with the help of the externally preset dust suction mechanism, the dust suction port can absorb and remove the odors and dust generated during the sponge cutting process, improve the air quality of the surrounding environment, and avoid the situation where workers work in a polluted environment for a long time, which may cause physical and mental harm to the workers.

[0019] 3. In this invention, a small amount of debris from the cutting sponge adheres to the surface of the hot wire body. The two clamping plates can be controlled to move towards each other, causing the cleaning pads on the adjacent side of the two clamping plates to come into contact with the hot wire body. As the first slider moves back and forth inside the first slide groove, it causes the moving frame and the two clamping plates inside it to move together, so that the debris on the surface of the hot wire body is removed during the friction with the two cleaning pads, eliminating the need for manual cleaning by subsequent personnel. During the cleaning of debris on the surface of the hot wire body, the side of each of the two rotating blocks with the dust suction port is controlled to rotate to a position close to the moving frame, so that the dust suction port can absorb and remove the debris cleaned off the surface of the hot wire body, preventing it from falling downwards and causing secondary pollution to the processing table.

[0020] 4. In this invention, when the hot wire body breaks unexpectedly during use, the first slider can be controlled to move the moving frame to the end of the hot wire body that is close to the broken end. The broken end of the hot wire body is placed between the two clamping plates, and the two clamping plates are driven by the second double-headed screw to assist in clamping and fixing the broken end of the hot wire body. This allows the hot wire body to continue cutting the subsequent sponge. After the entire sponge cutting work is completed, there is sufficient time to replace the hot wire body. This allows the entire device to continue working even if the hot wire body breaks, avoiding the problem of the hot wire body breaking and causing the inability to continue cutting the sponge.

[0031] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figures 1-8A multi-angle hot wire defoaming machine for processing semi-finished sponge products includes a processing table 1. Two columns 3 are installed on one outer wall of the processing table 1, and a movable frame 4 is set between the two columns 3. The interior of the two columns 3 is equipped with a drive mechanism for driving the movable frame 4 to move up and down. A rotating rod 10 is rotatably installed on the side of the movable frame 4 near the processing table 1. The side of the rotating rod 10 away from the movable frame 4 is connected to a mounting frame 6 through a telescopic mechanism. A rectangular groove 2 adapted to the mounting frame 6 is opened at the center of the top of the processing table 1. Through grooves 17 are opened at both ends of the mounting frame 6 near the processing table 1. The hot wire body 8 is inserted through both through grooves 17. The interior of both through grooves 17 is equipped with a fixing mechanism for fixing the two ends of the hot wire body 8. The interior of the mounting frame 6 is equipped with a cleaning mechanism for cleaning the surface of the hot wire body 8.

[0033] As a technical optimization of the present invention, the driving mechanism includes a first groove 13 formed on one side of the two columns 3 that are close to each other. A drive screw 14 and a slide rod are respectively installed inside the two first grooves 13. The two ends of the moving frame 4 are respectively engaged with the outer walls of the drive screw 14 and the slide rod. In actual use, a first motor is pre-installed at the top of one of the columns 3. The output end of the first motor is connected to the top of the drive screw 14, thereby driving the drive screw 14 to rotate inside the first groove 13, and driving the moving frame 4 to move up and down between the two columns 3.

[0034] As a technical optimization of the present invention, a drive motor 15 is installed on the outer wall of the movable frame 4 away from the processing table 1. The output end of the drive motor 15 is connected to the rotating part of the rotating rod 10. A plurality of telescopic limiting rods 11 are installed on the side of the movable frame 4 near the rotating rod 10. Two limiting holes 23 are provided on the side of the rotating rod 10 near the movable frame 4, which are adapted to the telescopic ends of the telescopic limiting rods 11. The drive motor 15 can drive the rotating rod 10 to rotate, and the position of the rotating rod 10 after rotation is assisted in limiting and fixing by the telescopic limiting rods 11.

[0035] As a technical optimization of the present invention, the telescopic mechanism includes a second groove 16 formed on the side of the rotating rod 10 away from the movable frame 4. A first double-ended screw 21 is rotatably mounted inside the second groove 16, and two moving blocks 22 are symmetrically mounted on the outer wall of the first double-ended screw 21. In actual use, a second motor is pre-installed on one side of the outer wall of the rotating rod 10. The output end of the second motor is connected to the first double-ended screw 21, thereby driving the first double-ended screw 21 to rotate inside the second groove 16, causing the two moving blocks 22 to move in a direction closer to or further apart.

[0036] As a technical optimization of the present invention, each of the two movable blocks 22 has a connecting rod 5 rotatably mounted on one end away from the first double-headed screw 21, and the two connecting rods 5 are hinged to one side of the outer wall of the mounting frame 6 at the end away from the movable block 22.

[0037] As a technical optimization of the present invention, the fixing mechanism includes screws rotatably mounted at both ends of the mounting bracket 6. One end of each screw extends into the through groove 17 and is connected to a fixing plate 18. The other end of each screw is connected to a rotating handle 19. By rotating the rotating handle 19, the screws are driven to rotate towards the inside of the through groove 17, causing the fixing plate 18 to move together inside the through groove 17 until one outer wall of the fixing plate 18 is in close contact with the hot wire body 8, thereby fixing the hot wire body 8 inside the through groove 17.

[0038] As an optimized technical solution of the present invention, the cleaning mechanism includes a first groove 20 formed on the outer wall of one side of the mounting frame 6. A first slider 24 is installed inside the first groove 20. An electric telescopic rod 7 is installed at the end of the first slider 24 away from the first groove 20. The telescopic end of the electric telescopic rod 7 is connected to a movable frame 12. A first linear motor is pre-installed inside the first groove 20. The first linear motor can drive the first slider 24 to move back and forth inside the first groove 20, thereby driving the electric telescopic rod 7 and the movable frame 12 to move back and forth together.

[0039] As a technical optimization of the present invention, a third groove 30 is provided on one inner wall of the movable frame 12. A second double-ended screw 31 is installed inside the third groove 30. Two clamping plates 32 are symmetrically installed on the outer wall of the second double-ended screw 31. A cleaning pad 33 is installed on the outer wall of the two clamping plates 32 that are close to each other. In actual use, a third motor is pre-installed on one outer wall of the movable frame 12. The output end of the third motor is connected to one end of the second double-ended screw 31, thereby driving the second double-ended screw 31 to rotate inside the third groove 30, so that the two clamping plates 32 can move towards each other or away from each other, causing the two cleaning pads 33 to come into close contact with the hot wire body 8.

[0040] As a technical optimization of the present invention, rotating blocks 25 are rotatably mounted on both outer walls of the movable frame 12, and multiple suction ports 26 are opened on one outer wall of each of the two rotating blocks 25. Both rotating blocks 25 are rotatably connected to the movable frame 12 via electric rotating shafts at both ends. The two electric rotating shafts can be driven by an external drive device, thereby causing the two rotating blocks 25 to rotate and adjust on both sides of the movable frame 12. Connection ports are pre-set on the outer walls of the two rotating blocks 25, and these ports can be connected to an externally pre-set dust collection mechanism via flexible hoses, allowing the external dust collection mechanism to absorb and clean smoke and dust through the multiple suction ports 26 after activation.

[0041] As a technical optimization of the present invention, two second sliding grooves 27 are opened on the outer walls of both sides of the movable frame 12 near the two rotating blocks 25. A second slider 28 is installed inside each of the two second sliding grooves 27. The ends of the two adjacent second sliders 28 away from the second sliding grooves 27 are connected to a mounting base 29. A protective plate 9 is rotatably installed inside each of the two mounting bases 29. A second linear motor is pre-installed inside each of the two second sliding grooves 27. The second linear motor can drive the second slider 28 to move back and forth within the second sliding groove 27, thereby driving the mounting base 29 and the protective plate 9 to move together. Both protective plates 9 are rotatably connected to the mounting base 29 via electric rotating shafts at both ends. The two electric rotating shafts can be driven by an external drive device, thereby causing the two protective plates 9 to rotate and adjust on both sides of the mounting base 29.

[0042] In this invention, when the user uses the device, the heating device pre-installed inside the mounting bracket 6 heats the hot wire body 8 installed inside the two through slots 17. After heating the hot wire body 8 to a specified temperature, refer to... Figure 1 As shown, the first slider 24 is controlled to move multiple components of the cleaning mechanism together to one end of the first chute 20. At this time, the sponge to be cut can be placed on the top of the processing table 1. The drive screw 14 is controlled to move the moving frame 4 downward, which in turn moves the mounting frame 6 and the hot wire body 8 and other components downward together to cut the sponge placed below longitudinally. Alternatively, the mounting frame 6 and the hot wire body 8 can be controlled to move downward to a specified height first, and then the sponge can be pushed towards the hot wire body 8 to achieve the effect of cutting the sponge laterally.

[0043] At the same time, the mounting frame 6 can be moved closer to the moving frame 4 by controlling the telescopic mechanism, so that the rotation of the mounting frame 6 is not hindered by the processing table 1. The drive motor 15 drives the rotating rod 10 to rotate 90 degrees, and the two vertical telescopic limit rods 11 limit and fix the position of the rotating rod 10 after rotation, so that the mounting frame 6 and the hot wire body 8 rotate at this time. Figure 2 In the vertical position shown, a longer end of the sponge can be placed on top of the processing table 1, and the sponge can be moved from left to right, allowing the hot wire body 8 to cut the longer sponge. If the sponge needs to be cut at an angle, a longer hot wire body 8 can be replaced. By controlling the extension or retraction of the electric telescopic rod 7, the hot wire body 8 inside the moving frame 12 is moved away from or closer to the mounting frame 6, so that the hot wire body 8 is V-shaped, which is convenient for cutting some sponges that need to be processed into bevels, thereby achieving the effect of cutting sponges at multiple angles.

[0044] During the cutting process of the hot wire body 8 on the sponge, odors and dust will be generated at the contact points between the hot wire body 8 and the sponge. These odors and dust will affect the air quality as they diffuse in the processing environment. Depending on the different usage states of the mounting frame 6, the first slider 24 can be controlled to move the electric telescopic rod 7 and the moving frame 12 to the cutting area near the sponge. The corresponding rotating block 25 with the dust suction port 26 can be controlled to rotate to the cutting area near the sponge. With the help of the externally preset dust suction mechanism, the dust suction port 26 can absorb and remove the odors and dust generated during the sponge cutting process, improve the air quality of the surrounding environment, and prevent workers from working in a polluted environment for a long time, which could cause physical and mental harm to the workers.

[0045] If the heating wire body 8 is used for a long time without being replaced, it is easy for the fixed ends of the heating wire body 8 to break when cutting relatively hard sponges due to repeated bending and deformation. If there is no replacement heating wire body 8 around the device, the first slider 24 can be controlled to move the moving frame 12 to the vicinity of the broken end of the heating wire body 8. The broken end of the heating wire body 8 is placed between the two clamping plates 32. The second double-headed screw 31 drives the two clamping plates 32 to move towards each other, so that the two clamping plates 32 cooperate to assist in clamping and fixing the broken end of the heating wire body 8. This allows the heating wire body 8 to continue cutting the subsequent sponges. After the entire sponge cutting work is completed, there is sufficient time to replace the heating wire body 8. This allows the entire device to continue working even if the heating wire body 8 breaks, avoiding the problem of the heating wire body 8 breaking and causing the inability to continue cutting sponges.

[0046] After the sponge cutting is completed, the surface of the processing table 1 needs to be cleaned. At this time, the first slider 24 can be controlled to move the moving frame 12 to the center position of the mounting frame 6, and the two protective plates 9 can be controlled to rotate to a state parallel to the hot wire body 8, so that the two protective plates 9 can shield and protect the hot wire body 8, and prevent the workers cleaning the processing table 1 from accidentally touching the hot wire body 8 with a high temperature, which could result in burns.

[0047] Furthermore, a small amount of debris from the cutting sponge will adhere to the surface of the hot wire body 8. If the hot wire body 8 does not show obvious deformation or breakage, the two clamping plates 32 can be controlled to move towards each other, causing the cleaning pads 33 on the side of the two clamping plates 32 that are close to each other to come into contact with the hot wire body 8. Since the cleaning pads 33 are made of high-temperature resistant materials in the prior art, and both sides of the two cleaning pads 33 that are close to each other are provided with rough surfaces, after the two cleaning pads 33 are in close contact with the hot wire body 8, as the first slider 24 moves back and forth inside the first slide groove 20, it causes the moving frame 12 and the two clamping plates 32 inside it to move together, so that the debris on the surface of the hot wire body 8 is removed during the friction with the two cleaning pads 33, without the need for subsequent manual cleaning by the staff; and during the cleaning of the debris on the surface of the hot wire body 8, the side of the two rotating blocks 25 with the dust suction port 26 is controlled to rotate to the position close to the moving frame 12, so that the dust suction port 26 can absorb and remove the debris cleaned off the surface of the hot wire body 8, avoiding the problem of falling downward and causing secondary pollution to the processing table 1.

[0048] If the hot wire body 8 needs to be replaced after use, the two protective plates 9 can be rotated to a position parallel to the hot wire body 8. Then, the two sets of corresponding second sliders 28 can be controlled to move the mounting base 29 and the protective plates 9 inside the second slide groove 27 towards the hot wire body 8 until the two protective plates 9 are in contact with the hot wire body 8. Since the two protective plates 9 are made of thermally conductive metal material, the high temperature inside the hot wire body 8 can be conducted out and dissipated after the two protective plates 9 are in contact with the hot wire body 8, so that the hot wire body 8 can be cooled down quickly. This makes it convenient for subsequent staff to quickly replace the hot wire body 8 without waiting for the hot wire body 8 to cool down naturally, thus improving the replacement efficiency of the hot wire body 8.

[0049] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
