Abstract

This utility model discloses a dust-free cutting device for processing parts of a tenter frame, relating to the field of dust-free cutting technology. The device includes a workbench, a dust-free cutting machine, and an explosion-proof vacuum cleaner. Two supports are connected to one side of the top of the workbench, and two rollers are connected between the supports. Both rollers are fitted with anti-slip sleeves. Through the arrangement of rollers, a housing, a spring, and a counterweight, when the dust-free cutting machine moves away from the explosion-proof vacuum cleaner during cutting, it pulls the flexible hose. The hose contacts the rollers and is guided by the rollers. When the hose is pulled, the rollers rotate due to friction, compressing the spring. Therefore, the rollers apply a reverse pulling force to the hose, tautning it and reducing the risk of damage caused by the hose sagging and contact with the sheet metal, workbench, or dust-free cutting machine. This facilitates hose protection, eliminating the need for frequent handling by operators and reducing the risk of cuts.

Description

Technical Field

[0001] This utility model relates to the field of dust-free cutting technology, specifically a dust-free cutting device for processing parts of a tenter frame. Background Technology

[0002] The difference between a dust-free cutting machine and a traditional cutting machine lies in its piping system. A pipe is installed on the protective cover of the dust-free cutting machine. The centrifugal force or negative pressure suction generated when the cutting blade rotates, or both, are used to remove the debris and dust generated during cutting. The end of the pipe can be connected to a dust filter bag or a bag vacuum cleaner. The negative pressure suction can come from the impeller linked to the tail of the cutting machine or an external bag vacuum cleaner.

[0003] However, during production, the tenter frame needs to cut large-sized metal materials such as sheet metal used to make its outer shell. There are two methods for cutting large-sized metal materials: one is to move the material while the cutting blade is fixed, and the other is to move the cutting blade while the metal material is fixed. The first method consumes more energy if the material size is large, and requires clamps to prevent the material from shifting during movement. Therefore, the second method is usually used, as it consumes less energy and can be limited by the weight of the material itself or by the operator's hand, or by clamps.

[0004] However, the cutter needs to be connected to a vacuum cleaner via a pipe to remove the debris and dust generated during cutting. As the cutter moves, it pulls on the pipe, so a flexible hose is necessary. However, the hose is prone to sagging due to gravity and may come into contact with the workbench or metal materials, potentially causing the pipe to be cut by the cutting blade or to rub against the sheet metal and other structures, affecting the lifespan of the structure and its dustproof effect. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a dust-free cutting device for processing parts of a tenter frame, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust-free cutting device for processing parts of a tenter frame, comprising a worktable, a dust-free cutting machine, and an explosion-proof vacuum cleaner. Two supports are connected to one side of the top of the worktable, and two rollers are connected between the two supports. Anti-slip sleeves are fitted onto the outside of both rollers, and pressure plates are connected to the outer surface and back of the anti-slip sleeves. Two housings are connected to the back of one of the supports, and two spring-loaded springs are connected between the two rollers and the two housings respectively. A flexible hose is provided between the dust-free cutting machine and the explosion-proof vacuum cleaner. A counterweight is connected to the outside of the flexible hose via an anti-slip pad.

[0007] By adopting the above technical solution, when the dust-free cutting machine moves away from the explosion-proof vacuum cleaner during the cutting process, the hose will be pulled. The hose contacts the roller and is guided by the roller. When the hose is pulled, the roller will rotate due to friction, compressing the spring. Therefore, the roller will apply a reverse pulling force to the hose, taut the hose, thereby reducing the occurrence of damage caused by the hose sagging and contact with the sheet metal, worktable, and dust-free cutting machine. Furthermore, by covering the outside of the roller with an anti-slip sleeve, the friction between the roller and the hose is increased, reducing the phenomenon of roller slippage affecting the subsequent hose retraction. In addition, the large contact area between the protective sleeve and the roller, combined with the pressure plate to tighten the protective sleeve, reduces the phenomenon of relative movement between the protective sleeve and the roller. When the cutter is near the explosion-proof vacuum cleaner during the reset process, the spring-loaded mechanism drives the rollers to reverse, thus pulling the hose. Simultaneously, a counterweight assists the rollers, applying a pulling force to one side of the hose through gravity. An anti-slip pad increases friction between the counterweight and the hose, making the connection more stable and preventing the counterweight from slipping and affecting the pulling operation. The rollers and counterweight keep the area of ​​the hose above the worktable taut, reducing the risk of damage from the hose sagging and contact with the sheet metal, worktable, or the dust-free cutting machine. When the counterweight contacts the ground, the rollers transport the hose independently. At this point, most of the hose is not above the worktable, so the rollers transport it without any impact.

[0008] Furthermore, the hose is in contact with the anti-slip sleeve, and the roller is rotatably connected to the bracket via a bearing.

[0009] By adopting the above technical solution, the friction between the roller and the hose is increased by putting an anti-slip sleeve on the outside of the roller, reducing the phenomenon of roller slippage affecting subsequent hose retraction; and the contact area between the protective sleeve and the roller is large, and the protective sleeve is pressed tightly by the pressure plate to reduce the phenomenon of relative movement between the protective sleeve and the roller.

[0010] Furthermore, both the anti-slip sleeve and the anti-slip mat are made of silicone rubber, and both the anti-slip sleeve and the anti-slip mat have anti-slip textures on their surfaces.

[0011] By adopting the above technical solution, the friction between the roller and the hose is increased by putting an anti-slip sleeve on the outside of the roller, reducing the phenomenon of roller slippage affecting the subsequent hose retraction; at the same time, the anti-slip pad increases the friction between the counterweight and the hose, making the connection between the counterweight and the hose more stable and preventing the counterweight from slipping off and affecting the pulling work.

[0012] Furthermore, the counterweight is made of stainless steel.

[0013] By adopting the above technical solution, the weight is similar to that of traditional cast iron and carbon steel, which can achieve a good effect of gravity-driven hose pulling. At the same time, it is corrosion-resistant, maintenance-free, aesthetically pleasing, non-magnetic, and reduces inconvenience during use.

[0014] Furthermore, electric slides are installed on both sides of the top of the workbench, and a dust-free cutting machine is installed at the output end of the electric slides via a bracket. The explosion-proof vacuum cleaner is located on one side of the workbench.

[0015] By adopting the above technical solution, after the dust-free cutting machine is started, the cutting blade at the bottom begins to rotate at high speed. After the explosion-proof vacuum cleaner is started, it generates suction. The explosion-proof vacuum cleaner is connected to the dust-free cutting machine through a hose, which generates suction inside the dust-free cutting machine. After the electric slide is started, it drives the dust-free cutting machine to move horizontally and contact the material to be cut to start cutting. This makes it easier to cut the material into the approximate shape required by the tenter frame parts. At the same time, the centrifugal force generated by the rotation of the cutting blade, together with the suction generated by the explosion-proof vacuum cleaner, will suck the cutting debris and dust into the explosion-proof vacuum cleaner for collection, avoiding external dust pollution.

[0016] Furthermore, the air outlet of the dust-free cutting machine and the air inlet of the explosion-proof vacuum cleaner are both fixed with pagoda connectors, and both ends of the hose are connected to the two pagoda connectors respectively. The hose is fitted with a clamp.

[0017] By adopting the above technical solution, the hose is connected to the cleanroom cutting machine and the explosion-proof vacuum cleaner through a combination of pagoda connector and clamp, which can effectively prevent the hose from falling off the cleanroom cutting machine or the explosion-proof vacuum cleaner after being pulled, thus increasing the structural stability.

[0018] Furthermore, the clamp is detachably connected to the hose, and the hose is detachably connected to the dust-free cutting machine and the explosion-proof vacuum cleaner via a pagoda connector.

[0019] By adopting the above technical solution, when the hose is damaged due to prolonged use, the staff first removes the bolts on the clamp and then disassembles the clamp. After that, the staff can remove the hose from the pagoda connector for replacement.

[0020] Furthermore, the bracket is detachably connected to the workbench by bolts, and the housing is detachably connected to the bracket by bolts. The roller has a groove on its back, and the spring is detachably connected to the roller and the housing.

[0021] By adopting the above technical solution, the operator can remove the bolts between the bracket and the worktable, and remove the bolts between the two brackets, which makes it easy to remove the roller from between the two brackets for replacement. The operator can also replace the spring by removing the bolts between the housing and the bracket.

[0022] Furthermore, the pressure plate is detachably connected to the roller and the anti-slip sleeve by bolts, and the anti-slip sleeve is detachably connected to the roller.

[0023] By adopting the above technical solution, after the roller is removed, the staff can remove the bolts on the pressure plate to remove the pressure plate. After removing the pressure plate, the staff can remove the protective cover from the roller by flipping or prying it off for replacement.

[0024] Furthermore, two counterweights and two anti-slip pads are provided, and the cross-sections of the two counterweights and anti-slip pads are both semi-circular. The two counterweights are connected by bolts.

[0025] By adopting the above technical solution, the staff can remove the bolts on the counterweight, thereby allowing the counterweight and anti-slip pad to be separated and replaced individually.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model, through the arrangement of rollers, housing, spring-loaded mechanism, and counterweight, allows the hose to be pulled when the cleanroom cutting machine moves away from the explosion-proof vacuum cleaner during cutting. The hose contacts the roller and is guided by the roller. When the hose is pulled, the roller rotates due to friction, compressing the spring-loaded mechanism. Therefore, the roller applies a reverse pulling force to the hose, keeping it taut and reducing the risk of damage from the hose sagging and contact with the sheet metal, worktable, or cleanroom cutting machine. When the cleanroom cutting machine returns to its restoring position near the explosion-proof vacuum cleaner, the spring-loaded mechanism drives the roller to reverse, pulling the hose. Simultaneously, the counterweight assists the roller, applying a pulling force to one side of the hose through gravity. Both components keep the area of ​​the hose above the worktable taut, further reducing the risk of damage from the hose sagging and contact with the sheet metal, worktable, or cleanroom cutting machine. This design facilitates hose protection, eliminating the need for frequent handling by operators and reducing the risk of cuts.

[0028] 2. This utility model, through the setting of anti-slip sleeve and pressure plate, increases the friction between the roller and the hose by covering the outside of the roller with an anti-slip sleeve, reducing the phenomenon of roller slippage affecting subsequent hose retraction; and the large contact area between the protective sleeve and the roller, combined with the pressure plate to press the protective sleeve tightly, reduces the phenomenon of relative movement between the protective sleeve and the roller; thus improving the stability by increasing friction.

[0029] 3. This utility model increases the friction between the counterweight and the hose by setting an anti-slip pad, making the connection between the counterweight and the hose more stable and preventing the counterweight from slipping and affecting the pulling work; thus improving the stability of the structure.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1:

[0040] A dust-free cutting device for processing parts of a tenter frame, such as Figures 1-6As shown, the system includes a workbench 1, a dust-free cutting machine 3, and an explosion-proof vacuum cleaner 4. Two supports 8 are connected to one side of the top of the workbench 1, and two rollers 9 are connected between the two supports 8. Each roller 9 is fitted with an anti-slip sleeve 10. A flexible hose 7 contacts the anti-slip sleeve 10. The rollers 9 are rotatably connected to the supports 8 via bearings. Pressure plates 11 are connected to the outer surface and back of the anti-slip sleeve 10. Two housings 12 are connected to the back of one of the supports 8, and two spring-loaded springs 13 are connected between the two rollers 9 and the two housings 12 respectively. A flexible hose 7 is installed between the dust-free cutting machine 3 and the explosion-proof vacuum cleaner 4. The flexible hose 7 is covered with an anti-slip sleeve 10. The sliding pad 15 is connected to a counterweight 14. Both the anti-slip sleeve 10 and the anti-slip pad 15 are made of silicone rubber, and both surfaces have anti-slip textures. The counterweight 14 is made of 304 stainless steel. When the dust-free cutting machine 3 moves away from the explosion-proof vacuum cleaner 4 during cutting, it pulls the hose 7. The hose 7 contacts the roller 9 and is guided by the roller 9. When the hose 7 is pulled, the roller 9 rotates due to friction, thus compressing the spring 13. Therefore, the roller 9 applies a reverse pulling force to the hose 7, tautning the hose 7 and reducing the drooping of the hose 7 against the sheet metal and worktable 1. To prevent damage caused by contact with the dust-free cutting machine 3, an anti-slip sleeve 10 is placed on the outside of the roller 9 to increase the friction between the roller 9 and the hose 7, reducing the phenomenon of the roller 9 slipping and spinning freely, which affects the subsequent retraction of the hose 7. Furthermore, the large contact area between the protective sleeve and the roller 9, combined with the pressure plate 11 to tighten the protective sleeve, reduces the relative movement between the protective sleeve and the roller 9. When the dust-free cutting machine 3 approaches the explosion-proof vacuum cleaner 4 during the reset process, the spring 13 drives the roller 9 to reverse, thereby pulling the hose 7. Simultaneously, the counterweight 14 assists the roller 9, and the counterweight 14 can exert gravity to pull the hose 7... While applying tension, the anti-slip pad 15 increases the friction between the counterweight 14 and the hose 7, making the connection between the counterweight 14 and the hose 7 more stable and preventing the counterweight 14 from slipping and affecting the pulling work. The area of ​​the hose 7 above the worktable 1 is kept taut by the roller 9 and the counterweight 14, thereby reducing the occurrence of damage caused by the hose 7 sagging and contacting the sheet, worktable 1, and dust-free cutting machine 3. When the counterweight 14 is in contact with the ground, the hose 7 is transported by the roller 9 alone. At this time, most of the area of ​​the hose 7 is not above the worktable 1, so the transport by the roller 9 alone has no impact.

[0041] See Figure 1In the above embodiment, electric slides 2 are installed on both sides of the top of the workbench 1. A dust-free cutting machine 3 is installed at the output end of the electric slide 2 via a bracket. An explosion-proof vacuum cleaner 4 is located on one side of the workbench 1. After the dust-free cutting machine 3 is started, the cutting blade at its bottom begins to rotate at high speed. After the explosion-proof vacuum cleaner 4 is started, it generates suction. The explosion-proof vacuum cleaner 4 is connected to the dust-free cutting machine 3 through a hose 7, so that suction is generated inside the dust-free cutting machine 3. After the electric slide 2 is started, it drives the dust-free cutting machine 3 to move horizontally and contact the material to be cut to start cutting. This makes it easier to cut the material into the approximate shape required by the tenter frame parts. At the same time, the centrifugal force generated by the rotation of the cutting blade will cooperate with the suction generated by the explosion-proof vacuum cleaner 4 to suck the cutting debris and dust into the explosion-proof vacuum cleaner 4 for collection, avoiding external dust pollution.

[0042] Example 2:

[0043] Based on the above embodiment 1, in order to increase the stability of the hose 7 connection, the following settings are now implemented.

[0044] See Figure 1 , Figure 5 and Figure 6 In the above embodiment, both the air outlet of the dust-free cutting machine 3 and the air inlet of the explosion-proof vacuum cleaner 4 are fixed with pagoda connectors 5. The two ends of the hose 7 are connected to the two pagoda connectors 5 respectively. The hose 7 is detachably connected to the dust-free cutting machine 3 and the explosion-proof vacuum cleaner 4 through the pagoda connectors 5. The hose 7 is fitted with a clamp 6. The clamp 6 is detachably connected to the hose 7. The hose 7 is limited by the combination of the pagoda connectors 5 and the clamp 6, which can effectively prevent the hose 7 from falling off the dust-free cutting machine 3 or the explosion-proof vacuum cleaner 4 after being pulled, thus increasing the structural stability. When the hose 7 is damaged after prolonged use, the operator first removes the bolts on the clamp 6 and then disassembles the clamp 6. Then the operator can remove the hose 7 from the pagoda connectors 5 for replacement.

[0045] Example 3:

[0046] Based on the above embodiment one, the following settings are now adopted to facilitate the replacement of damaged structures.

[0047] See Figures 1-4In the above embodiment, the bracket 8 is detachably connected to the workbench 1 by bolts, the housing 12 is detachably connected to the bracket 8 by bolts, the roller 9 has a groove on its back, the spring 13 is detachably connected to the roller 9 and the housing 12, the pressure plate 11 is detachably connected to the roller 9 and the anti-slip sleeve 10 by bolts, the anti-slip sleeve 10 is detachably connected to the roller 9, and two counterweights 14 and two anti-slip pads 15 are provided. The cross-sections of the two counterweights 14 and the anti-slip pads 15 are both semi-circular, and the two counterweights 14 are detachably connected by bolts. When the roller 9, counterweights 14, and other components are damaged due to prolonged use, the worker... The operator removes the bolts on the counterweight 14, allowing the counterweight 14 and anti-slip pad 15 to be separated and replaced individually. The operator removes the bolts between the bracket 8 and the workbench 1, and also removes the bolts between the two brackets 8, making it easier to remove the roller 9 from between the two brackets 8 for replacement. The operator also removes the bolts between the housing 12 and the bracket 8 to replace the spring spring 13. After removing the roller 9, the operator can remove the bolts on the pressure plate 11 to remove the pressure plate 11. After removing the pressure plate 11, the operator can remove the protective cover from the roller 9 by flipping or prying it for replacement.

[0048] The implementation principle of this utility model is as follows: First, the staff places materials such as plates, bars, rods, or steel structures such as angle steel and channel steel, or aluminum alloy profiles, used to make the shell and other parts of the tenter frame on the top of the workbench 1. Then, the materials are limited by their own weight, manual positioning by the staff, or by the addition of clamps; clamps are known in the prior art and there are many types, so this technical solution does not limit or elaborate on them; thus limiting the materials, the staff can then start the electric slide table 2, the dust-free cutting machine 3, and the explosion-proof vacuum cleaner 4.

[0049] After the dust-free cutting machine 3 is started, its cutting blade at the bottom begins to rotate at high speed. After the explosion-proof vacuum cleaner 4 is started, it generates suction. The explosion-proof vacuum cleaner 4 is connected to the dust-free cutting machine 3 through the hose 7, so that the dust-free cutting machine 3 generates suction inside. After the electric slide table 2 is started, it drives the dust-free cutting machine 3 to move horizontally and contact the material to be cut to start cutting. This makes it easier to cut the material into the approximate shape required by the tenter frame parts. At the same time, the centrifugal force generated by the rotation of the cutting blade will work with the suction generated by the explosion-proof vacuum cleaner 4 to suck the cutting debris and dust into the explosion-proof vacuum cleaner 4 for collection, avoiding external dust pollution.

[0050] When the dust-free cutting machine 3 moves away from the explosion-proof vacuum cleaner 4 during the cutting process, it will pull the hose 7. The hose 7 contacts the roller 9 and is guided by the roller 9. When the hose 7 is pulled, the roller 9 will rotate due to friction, thereby compressing the spring 13. Therefore, the roller 9 will apply a reverse pulling force to the hose 7, making the hose 7 taut. This reduces the phenomenon of the hose 7 sagging and contacting the sheet metal, workbench 1, and dust-free cutting machine 3, which would cause damage. In addition, by putting an anti-slip sleeve 10 on the outside of the roller 9, the friction between the roller 9 and the hose 7 is increased, reducing the phenomenon of the roller 9 slipping and spinning freely, which would affect the subsequent retraction of the hose 7. Furthermore, the protective sleeve has a large contact area with the roller 9, and the pressure plate 11 presses the protective sleeve tightly, reducing the phenomenon of relative movement between the protective sleeve and the roller 9.

[0051] When the dust-free cutting machine 3 approaches the explosion-proof vacuum cleaner 4 during the reset process, the spring 13 will drive the roller 9 to reverse, thereby pulling the hose 7. At the same time, the counterweight 14 assists the roller 9. The counterweight 14 can apply a pulling force to one side of the hose 7 by gravity. At the same time, the anti-slip pad 15 increases the friction between the counterweight 14 and the hose 7, making the connection between the counterweight 14 and the hose 7 more stable and preventing the counterweight 14 from slipping and affecting the pulling work. The area of ​​the hose 7 above the worktable 1 is kept taut by the roller 9 and the counterweight 14, thereby reducing the occurrence of damage caused by the hose 7 sagging and contacting the sheet metal, worktable 1, and dust-free cutting machine 3. When the counterweight 14 contacts the ground, the roller 9 alone transports the hose 7. At this time, most of the area of ​​the hose 7 is not above the worktable 1, so the transport by the roller 9 alone has no impact.

[0052] The hose 7 is connected to the cleanroom cutting machine 3 and the explosion-proof vacuum cleaner 4 by a combination of a pagoda connector 5 and a clamp 6, which effectively prevents the hose 7 from falling off the cleanroom cutting machine 3 or the explosion-proof vacuum cleaner 4 after being pulled, thus increasing structural stability. When the hose 7 is damaged after prolonged use, the staff first removes the bolts on the clamp 6 and then disassembles the clamp 6. The staff can then remove the hose 7 from the pagoda connector 5 for replacement.

[0053] When components such as roller 9 and counterweight 14 become damaged due to prolonged use, the operator removes the bolts on counterweight 14, allowing the counterweight 14 and anti-slip pad 15 to be disassembled and replaced individually. The operator removes the bolts between bracket 8 and workbench 1, and also removes the bolts between the two brackets 8, making it easier to remove roller 9 from between the two brackets 8 for replacement. The operator can also replace the clock spring 13 by removing the bolts between housing 12 and bracket 8. After removing roller 9, the operator can remove the bolts on pressure plate 11 to remove pressure plate 11. After removing pressure plate 11, the operator can remove the protective cover from roller 9 by flipping or prying it off for replacement.
