Description

Technical Field

[0001] This invention relates to the field of sawing technology, specifically to an electric chainsaw for processing acrylic sheets. Background Technology

[0002] Acrylic sheets can be sawed using precision sliding table saws, CNC panel saws, mini bench saws, reciprocating panel saws, or specialized plastic sawing machines. These should be equipped with special saw blades and the sawing speed should be controlled to prevent the plastic from melting at the cut. These sawing machines are good at straight lines or simple angle sawing; for complex shapes, curves, or high-precision cutouts, laser sawing machines or CNC engraving machines are required.

[0003] Use a hard-toothed saw blade to avoid burrs or high-temperature melting during sawing. Acrylic has poor thermal conductivity, so it needs to be sawed at medium to low speeds to avoid yellowing or sticking of the cut.

[0004] Traditional saw teeth gradually heat up during continuous sawing friction, requiring a technology that can quickly replace saw teeth to prevent the sawing point of the acrylic sheet from melting due to prolonged friction and heating of a single saw tooth. At the same time, it is also necessary to cool down the replaced saw teeth to ensure that the saw teeth can be recycled for subsequent sawing. To this end, the present invention provides an electric chain saw for acrylic sheet processing. Summary of the Invention

[0005] The purpose of this invention is to provide an electric chainsaw for processing acrylic sheets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electric chainsaw for processing acrylic sheets, comprising an electric chainsaw mechanism, a telescopic cylinder mechanism for driving the electric chainsaw mechanism to rise and fall, a frame for supporting the telescopic cylinder mechanism, and a platform plate fixed at the bottom of the frame. An acrylic sheet is conveyed above the platform plate, and the electric chainsaw mechanism descends to saw the acrylic sheet. The electric chainsaw mechanism includes an electric chainsaw power body fixedly connected to the telescopic end of the telescopic cylinder mechanism, a sawing execution component driven by one end of the electric chainsaw power body, and a long box cover covering the sawing execution component. The sawing execution component includes: The chain is driven and transported by the power unit of the electric chainsaw, the chainsaw guide plate is used to support and guide the chain, and the saw teeth are installed at fixed intervals on the outside of the chain. The saw teeth are transported along a flat closed loop on the chain. The saw teeth slide over the acrylic plate to complete the sawing. The saw teeth are changed to avoid overheating and melting the acrylic plate. One end of the chainsaw guide plate is fixed to the power unit of the electric chainsaw.

[0007] The sawing execution component further includes: A reinforcing rail plate fixed to the guide plate of the chainsaw guides the saw tooth component to move laterally. A cold flow box assembly is distributed on the upper side of the chain, which is used to blow air to dissipate heat from the sawtooth components passing by on one side.

[0008] The sawing execution component further includes: A long ring track body is distributed parallel to one side of the chain. Multiple track grooves are opened on the long ring track body to guide the saw tooth component, and the distance between any two adjacent parallel track grooves is fixed. The slot changing frame and the telescopic device that drives the slot changing frame to move are provided. The slot changing frame is distributed at the notches opened in the long ring track body and is used to guide the saw tooth component to the new track slot. The telescopic device is fixed to the electric saw guide plate.

[0009] The sawtooth component includes a cutter holder fixed on a single link of the chain, a decorative cutter head supported on the cutter holder, a tooth-changing adjustment group for driving the decorative cutter head, and a tube for blowing air into the middle of the decorative cutter head. A support plate is provided on the cutter holder to fix the support tube. One end of the tooth-changing adjustment group is inserted into a track groove on a long ring rail. A through groove is provided on the cutter holder for the reinforced rail plate encountered to pass through.

[0010] The cutting head includes a cutting shaft supported by a cutting tool holder, a heat-conducting plate fixed at one end of the cutting shaft, multiple cutting tools arranged around the outside of the heat-conducting plate, multiple heat-conducting tubes embedded in the heat-conducting plate, and a ventilation duct fixed in the middle of the heat-conducting plate. The edge of the heat-conducting plate is provided with heat-conducting protrusions to be embedded in the cutting tools. One end of each heat-conducting tube extends into the ventilation duct, and the other end extends outside the heat-conducting plate. The heat-conducting tubes are arranged in a meandering pattern within the heat-conducting protrusions to absorb heat from the cutting tools.

[0011] The fitting includes a curved pipe and an arc plate fixed at one end of the curved pipe. The curved pipe of the fitting is connected to the air duct. The air duct and the fitting rotate relative to each other to replace the heat-conducting pipe sealed by the arc plate of the fitting.

[0012] The cold flow box assembly includes a long cold box connected to a row of pipes, an inlet on one side of the long cold box, a belt wrapped around the side of the long cold box, a spline gear for driving the belt, an actuation shaft fixed in the middle of the spline gear, and a bracket for supporting the actuation shaft, the bracket being fixed to the electric saw guide plate.

[0013] A long strip notch is opened on one side of the long cold box, and a section of the belt blocks the notch of the long cold box. Air holes are opened at fixed intervals on the belt, and the air holes meet and communicate with the pipe on one side. The spline gear and the multi-tooth grooves arranged on the edge of the belt mesh.

[0014] The gear-changing adjustment assembly includes a vertical shaft that drives perpendicularly to the cutter shaft, a worm gear with a worm wheel fixed at one end of the vertical shaft, an amplifying gear with a gear drive fixed at the end of the worm gear, an amplifying shaft fixed in the middle of the amplifying gear, a rack with a gear drive fixed at the end of the amplifying shaft, and a traction rod fixed on one side of the rack. The traction rod is inserted into a track groove on the long ring rail body. The traction rod is transported in the track groove for one revolution and changes to a new track groove after being guided by the slot-changing frame.

[0015] The vertical shaft, worm gear, and amplification shaft are all mounted on the tool post, and the rack slides directionally on the tool post.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses multiple saw teeth components to cut by sliding across an acrylic plate one by one. After a single saw tooth component cuts, it automatically changes its internal teeth to avoid the sawing part on the acrylic plate from heating up due to long-term friction of a single tooth. In addition, the removed blades are cooled by blowing air to dissipate heat, and the cooled blades can be recycled for subsequent sawing.

[0017] 2. In this invention, each tool is provided with a heat pipe on one side for heat dissipation. Cool air flows through the heat pipe to effectively absorb the heat emitted from the tool nearby, thus cooling the tool down. In addition, cool air only flows through the heat pipe on the side of the tool that is generating heat, while the heat pipe on the side of the tool that is not hot is shut off to avoid energy loss and waste.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions 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.

[0035] Please see Figures 1 to 15This invention provides a technical solution: an electric chainsaw for processing acrylic sheets, comprising an electric chainsaw mechanism 1, a telescopic cylinder mechanism 2 for driving the electric chainsaw mechanism 1 to rise and fall, a frame 3 for supporting the telescopic cylinder mechanism 2, and a platform plate 4 fixed at the bottom of the frame 3. An acrylic sheet 5 is conveyed above the platform plate 4, and the electric chainsaw mechanism 1 descends to cut the acrylic sheet 5. The telescopic cylinder mechanism 2 can be a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic cylinder. One end of the acrylic sheet 5 is connected to a horizontal displacement mechanism, which can be a screw and nut transmission mechanism, such as a ball screw combined with a linear guide, suitable for CNC sawing machines that require precise control of the sawing size; or it can be a gear and rack combined with a servo drive. The horizontal displacement mechanism clamps one end of the acrylic plate 5 and moves it laterally along the track on the sawing machine, so that different parts of the acrylic plate 5 pass under the electric chainsaw mechanism 1 one by one. Each time the acrylic plate 5 stops, the electric chainsaw mechanism 1 descends and cuts the acrylic plate 5. The electric chainsaw mechanism 1 includes an electric chainsaw power body 6 fixedly connected to the telescopic end of the telescopic cylinder mechanism 2, a sawing execution component 7 driven by one end of the electric chainsaw power body 6, and a long box cover 8 covering the sawing execution component 7. The long box cover 8 is connected to lifting control instruments at both ends to control the independent lifting and lowering of the long box cover 8. When the electric chainsaw mechanism 1 descends to cut the acrylic plate 5, the long box cover 8 descends to cover the electric chainsaw mechanism 1 to prevent debris from flying and to prevent personnel from accidentally touching and being injured.

[0036] The sawing execution component 7 includes a chain 10 driven and conveyed by the electric chainsaw power body 6, an electric chainsaw guide plate 9 for supporting and guiding the chain 10, and saw teeth 11 installed at fixed intervals on the outside of the chain 10. The saw teeth 11 are conveyed along a flat closed loop on the chain 10. The saw teeth 11 slide over the acrylic plate 5 to complete the sawing, and the saw teeth 11 avoid overheating and melting the acrylic plate 5 by changing teeth. One end of the electric chainsaw guide plate 9 is fixed to the electric chainsaw power body 6.

[0037] The chain 10 drives the saw tooth component 11 to slowly descend and feed. At the same time, the saw tooth component 11 is horizontally conveyed on the chain 10. The saw tooth component 11 contacts the acrylic plate 5 below and gradually moves laterally to saw the acrylic plate 5.

[0038] In this embodiment, a saw tooth component 11 is installed on the chain 10 every seven links. The saw tooth component 11 is fixed on a single link, which can also increase the number density of the saw tooth components 11. In this way, more saw tooth components 11 can be cut across the acrylic plate 5 in a short time, resulting in faster sawing efficiency. However, it requires a larger power load to drive the chain 10. The number of saw tooth components 11 on the chain 10 can be adjusted according to the processing needs of the enterprise and the amount of power that the electric chainsaw power unit 6 can provide. The number of saw tooth components 11 does not affect the subsequent tooth replacement. Any saw tooth component 11 will automatically replace its tooth once after each closed loop of conveying.

[0039] Reference Appendix Figure 6 The sawing execution component 7 also includes a reinforcing rail plate 12 fixed on the electric saw guide plate 9, a cold flow box group 13 distributed on the upper side of the chain 10, a long ring rail body 14 parallel to one side of the chain 10, a slot changing frame 15, and an extension device 16 for driving the slot changing frame 15 to move. The reinforcing rail plate 12 guides the saw tooth component 11 to move laterally. The cold flow box assembly 13 is used to blow air to dissipate heat from the serrated component 11 that passes by on one side.

[0040] Reference Appendix Figure 5 The long ring rail body 14 has multiple track grooves to guide the sawtooth component 11, and the distance between any two adjacent parallel track grooves is fixed. The slot changing frame 15 is distributed at the gaps partially opened in the long ring track body 14 and is used to guide the saw tooth component 11 to the new track slot. The telescopic device 16 is fixed on the electric saw guide plate 9.

[0041] The new track groove and sawtooth component 11 are connected at one end, combined with the attached... Figure 10 This is understood, and further understood in conjunction with the fact that the long ring track body 14 is a flat, closed ring body. The long ring track body 14 has an outer track groove 141, a middle track groove 142, and an inner track groove 143. The long ring track body 14 is a ring-shaped track structure. The outer track groove 141, the middle track groove 142, and the inner track groove 143 are distributed in the thickness direction on the side facing the chain 10. The serrated component 11 moves from left to right, and one end of the serrated component 11 is inserted into the outer track groove 141. The serrated component 11 is circulated along the long ring track 14 for one revolution, passing through the downward inclined track 152 on the slot changing frame 15, and then being transported into the inner track groove 143. The serrated component 11 is then circulated along the long ring track 14 for one revolution, that is, during one revolution in the inner track groove 143, the telescopic device 16 drives the slot changing frame 15 to shift and change gears. The left end of the upward inclined track 151 on the slot changing frame 15 descends and aligns with the inner track groove 143, while the right end of the upward inclined track 151... The sawtooth component 11 is connected to the middle track groove 142, thus guiding the insertion point on the sawtooth component 11 from the inner track groove 143 to the middle track groove 142. The sawtooth component 11 is conveyed around the middle track groove 142. The telescopic device 16 drives the slot changing frame 15 again. The left end of the upper inclined track 151 is connected to the middle track groove 142, and the right end of the upper inclined track 151 is connected to the outer track groove 141, thereby guiding the sawtooth component 11 back to the outer track groove 141. This cycle continues. The sawtooth component 11 is conveyed along one track groove on the long ring track body 14. When it is about to complete one revolution, it will be changed to the track groove of the next long ring track body 14. The chain 10 is in a flat closed loop state. All the sawtooth components 11 on the chain 10 are conveyed synchronously. All the sawtooth components 11 are conveyed in one track groove of the long ring track body 14. After encountering the slot changing frame 15, they are automatically changed to another track groove. This invention controls the sawtooth component 11 to change teeth in reverse by changing the track groove.

[0042] Reference Appendix Figure 11 The saw tooth component 11 includes a cutter holder 19 fixed on a single link of the chain 10, a decorative cutter head 20 supported on the cutter holder 19, a tooth-changing adjustment group 21 for driving the decorative cutter head 20, and a tube 22 for blowing air into the middle of the decorative cutter head 20. A support plate is provided on the cutter holder 19 to fix and support the tube 22. One end of the tooth-changing adjustment group 21 is inserted into a track groove on the long ring rail body 14. A through groove is provided on the cutter holder 19 for the reinforced rail plate 12 to pass through.

[0043] Reference Appendix Figure 12 The decorative cutter head 20 includes a cutter shaft 23 supported by a cutter holder 19, a heat-conducting plate 24 fixed at one end of the cutter shaft 23, a plurality of cutters 25 arranged around the outside of the heat-conducting plate 24, a plurality of heat-conducting pipes 26 embedded in the heat-conducting plate 24, and a diffuser 27 fixed in the middle of the heat-conducting plate 24. The edge of the heat-conducting plate 24 is provided with heat-conducting protrusions to be embedded in the cutters 25. One end of the heat-conducting pipes 26 extends into the diffuser 27 and the other end extends to the outside of the heat-conducting plate 24. The heat-conducting pipes 26 are arranged in a meandering pattern in the heat-conducting protrusions to absorb heat from the cutters 25.

[0044] The tool shaft 23 is movably fitted into a shaft hole at the outer end of the tool holder 19. Figure 12 The cutter shaft 23 rotates one-third of a turn, driving the heat-conducting plate 24, which in turn drives all the cutters 25 to rotate. The bottom cutter 25 is used to saw the acrylic sheet 5 it encounters. Friction causes the temperature of the cutter 25 to rise. If sawing continues, the cutter 25 may melt the acrylic sheet 5 it is in contact with. Therefore, after a single sawing operation, the heat-conducting plate 24 rotates, the overheated cutter 25 leaves, and a new cutter 25 appears. Figure 12 The bottom position is used for the next sawing of acrylic sheet 5. In summary, after each pass of the decorative cutter head 20 over acrylic sheet 5, the decorative cutter head 20 automatically rotates and changes teeth to avoid continuous work and heat generation by a single cutter.

[0045] Reference Appendix Figure 13 Understandably, fitting 22 includes a curved pipe and an arc plate fixed at one end of the curved pipe. The curved pipe of fitting 22 is connected to the air duct 27. The air duct 27 and fitting 22 rotate relative to each other to replace the heat-conducting pipe 26 blocked by the arc plate of fitting 22.

[0046] The cutter shaft 23 rotates one-third of a turn, and a new cutter 25 is brought to the sawing position. The cutter shaft 23 continues to rotate one-third of a turn, and the third cutter 25 swings to the sawing position. Then, the cutter shaft 23 reverses two-thirds of a turn, and the first cutter 25, which has cooled down, comes to the sawing position. This cycle continues, with each cutter 25 taking turns to the sawing position, and then sawing the acrylic sheet 5 encountered. When the cutter shaft 23 drives the heat transfer plate 24 to rotate, the heat transfer pipe 26, which is connected to the inner cavity of the air duct 27, also changes accordingly. That is, after a single cutter 25 saws the acrylic sheet 5, it is transported to one side of the cold flow box assembly 13. The cold flow box assembly 13 blows air onto the encountered pipe 22. An air pump is set outside the saw to blow air onto the cold flow box assembly 13. Air is injected, and then the airflow is injected into the diffuser 27 through the connected fitting 22, then flows through the heat pipe 26 before being discharged. The heat on the cutting tool 25 is transferred to the heat-conducting plate 24 and carried away by the airflow in the heat pipe 26, thus achieving heat transfer and heat dissipation. This heat pipe 26 is the one that is not blocked by the arc plate on the fitting 22. In addition, a cooling mechanism can be set in the cold flow box assembly 13, so that the external air flowing through the cold flow box assembly 13 is cooled. Alternatively, an air pump can directly guide the cold air from the external cooling mechanism to the cold flow box assembly 13, and then diffuse it onto the cutting tool head 20. When the cooled airflow passes through the heat pipe 26, it can more efficiently absorb the heat dissipated from the cutting tool 25. (See attached diagram) Figure 8 It is understood that the cold flow box assembly 13 has a certain length, and the pipe 22 is transported along one side of the cold flow box assembly 13. For a period of time, the pipe 22 can continuously receive airflow, and finally the airflow continuously flows through the heat conduction pipe 26. The continuous heat conduction and heat dissipation are used to cool the tool 25 and the heat conduction plate 24. In this invention, the heat conduction and cooling medium, cold air, can also be replaced with cold water, and the air pump can be replaced with a cold water supply mechanism.

[0047] The cold flow box assembly 13 includes a long cold box 136 connected to a row of pipes, an inlet 131 opened on one side of the long cold box 136, a belt 135 wrapped around the side of the long cold box 136, a sprocket 133 that drives the belt 135 to transport, an actuation shaft 132 fixed in the middle of the sprocket 133, and a bracket 134 that supports the actuation shaft 132. The bracket 134 is fixed on the electric saw guide plate 9.

[0048] The drive shaft 132 is movably sleeved in the shaft hole opened on the bracket 134. Multiple drive gears 133 can be set on one side of the belt 135. A servo motor assembly is set on one side of the electric saw guide plate 9 to drive the multiple drive shafts 132. The rotation of the gears 133 causes the belt 135 to convey. The conveying speed of the belt 135 is the same as the conveying speed of the chain 10. In this way, the cold flow box assembly 13 and the pipe 22 on one side can be stably connected to one end for a period of time.

[0049] A long strip notch is opened on one side of the long cold box 136. A section of the belt 135 blocks the notch of the long cold box 136. Air holes 130 are opened at fixed intervals on the belt 135. The air holes 130 meet and communicate with the pipe 22 on one side. The flower gear 133 and the multi-tooth grooves arranged on the edge of the belt 135 mesh.

[0050] The spacing between two adjacent air holes 130 is the same as the spacing between two adjacent sawtooth components 11. External cold air is injected into the long cold box 136 through the inlet 131, and then discharged through the long strip notch on one side of the long cold box 136. Specifically, it is discharged through the air hole 130 at the long strip notch to the docked pipe 22, and then ventilates and dissipates heat for the flower cutter head 20.

[0051] The gear changing adjustment group 21 includes a vertical shaft 216 that is perpendicular to the cutter shaft 23, a worm 215 that is fixed to one end of the vertical shaft 216 and driven by a worm gear, an amplifying gear 214 that is fixed to the end of the worm 215 and driven by a gear, an amplifying shaft 213 that is fixed in the middle of the amplifying gear 214, a rack 212 that is fixed to the end of the amplifying shaft 213 and driven by a gear, and a traction rod 211 fixed to one side of the rack 212. The traction rod 211 is inserted into a track groove on the long ring rail body 14. The traction rod 211 is transported in the track groove for one revolution and changes to a new track groove after being guided by the slot changing frame 15.

[0052] The vertical shaft 216, worm gear 215 and amplifying shaft 213 are all mounted on the tool holder 19, and the rack 212 slides directionally on the tool holder 19. A bevel gear is fixed at the end of the vertical shaft 216 to drive the bevel gear fixed at the end of the cutter shaft 23 in a different direction. The vertical shaft 216, worm 215 and amplifying shaft 213 are respectively movably sleeved in different through holes opened on the tool holder 19. The rack 212 passes through the T-shaped slide groove opened on the tool holder 19. As mentioned before, the sawtooth component 11 slides along a track groove on the long ring rail body 14. This means that the guide bar 211 slides in a single track groove. The guide bar 211 delivers one revolution, and after being guided by the slot changing frame 15, it is delivered to other track grooves. After the guide bar 211 changes position, it drives the rack 212. The rack 212 moves to drive the amplifying shaft 213 to rotate. Then, it drives the worm 215 through the amplifying gear 214, and then drives the cutter shaft 23 through the vertical shaft 216. In this way, the rotation of the cutter shaft 23 realizes the subsequent gear change. The guide bar 211 changes the track groove once for each revolution, triggering a gear change. Each saw blade 25 is replaced after each sawing operation to prevent the single blade from overheating and melting the local plastic of the acrylic sheet 5 due to prolonged friction. The replaced saw blade 25 is cooled by air blowing and can be recycled for subsequent sawing operations after it has cooled down.
