[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, the present invention proposes a PET foam board cutting device, including a machine table 1 and a saw wire 13. The machine table 1 includes a cutting table and a machine head. The machine head is located directly above the cutting table. A driving mechanism for driving the saw wire 13 is provided inside the machine table 1. The saw wire 13 is led out of the machine table 1 from the machine head and introduced into the machine table 1 from the cutting table. The saw wire 13 between the machine head and the cutting table is used to cut the PET foam board.

[0022] Furthermore, a servo slide module 4 is provided on one side of the cutting table. The servo slide module 4 includes two servo slides with transmission directions perpendicular to each other, so that it can move in two directions in the horizontal plane. The servo slide module 4 is provided with a clamp 5 for clamping the plate. The servo slide module 4 can drive the clamp 5 to move in two directions in the horizontal plane, and the servo slide module 4 is connected to an external CNC module, which drives the servo slide module 4 to move according to a preset program.

[0023] In this way, the PET foam board to be cut is clamped by the clamp 5, and the servo slide module 4 is used to drive the PET foam board to move on the cutting table according to the preset cutting path, and the running saw wire 13 is used to cut the PET foam board.

[0024] Combination Figure 3 As shown, the driving mechanism includes a plurality of wire wheels 11 distributed inside the machine 1, and the saw wire 13 passes through the plurality of wire wheels 11 in sequence. The driving mechanism also includes a power component 12, and the output end of the power component 12 is connected to any one of the wire wheels 11 to drive the wire wheels 11 to rotate, and the wire wheels 11 drag the saw wire 13 to run, and the saw wire 13 runs from the head of the machine 1 to the cutting table surface (such as Figure 3 as shown).

[0025] In a specific embodiment, the power component 12 includes a motor and a transmission box, the output end of the motor is connected to the input end of the transmission box, the output end of the transmission box is connected to the reel 11, and the motor drives the reel 11 to rotate after adjusting the speed through the transmission box and converting the direction of the output shaft.

[0026] Combination Figure 1 and Figure 4 As shown, a wire storage mechanism 2 is provided at the head of the machine platform 1 , and the saw wire 13 is introduced into the wire storage mechanism 2 from the head of the machine platform. The wire storage mechanism 2 can release or tension the saw wire 13 .

[0027] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the bottom end of the wire storage mechanism 2 is movably connected to the support shell 3, and the upper and lower ends of the support shell 3 are respectively connected to the upper limit wheel 31 and the lower limit wheel 32. After the saw wire 13 is drawn out from the wire storage mechanism 2, it enters the support shell 3 and passes through the upper limit wheel 31 and the lower limit wheel 32 in sequence (as shown in FIG. Figure 5 As shown in FIG. 1 , the saw wire 13 extends from the lower limit wheel 32 to the cutting table, and is introduced into the machine table 1 from the cutting table (as shown in FIG. Figure 3 shown); The bottom end of the support shell 3 is configured to be able to swing along the rotation plane of the lower limit wheel 32, and the swinging direction can enable the lower limit wheel 32 to support the saw wire 13 (such as Figure 4 As shown in FIG. 1 ), when the support shell 3 swings, the lower limit wheel 32 at the bottom end of the support shell 3 moves in the horizontal direction. At this time, under the support of the lower limit wheel 32, the cutting path of the saw wire 13 between the lower limit wheel 32 and the cutting table is adjusted in the horizontal direction (as shown in FIG. 1 ). Figure 3 and Figure 4 As shown), the saw wire 13 forms an inclined cutting path. At this time, when the saw wire 13 cuts the PET foam board, the cutting surface is an inclined surface. By adjusting the swing angle of the support shell 3, the cutting angle of the saw wire 13 is adjusted, and the inclination angle of the cutting surface of the PET foam board can be adjusted; At the same time, when the support shell 3 swings and the saw wire 13 is tilted by the support of the lower limit wheel 32, the cutting path of the saw wire 13 between the lower limit wheel 32 and the cutting table increases. At this time, the wire storage mechanism 2 releases the saw wire 13 to meet the tilting requirement of the saw wire 13. When the saw wire 13 returns to a vertical state, the wire storage mechanism 2 tensions the saw wire 13 so that the excess saw wire 13 is stored in the wire storage mechanism 2 to meet the tension of the saw wire 13 during cutting, thereby preventing the saw wire 13 from being too loose and affecting the cutting accuracy. When the saw wire 13 between the lower limit wheel 32 and the cutting table is tilted, the saw wire 13 above the lower limit wheel 32 will also tilt, and the upper limit wheel 31 will support the saw wire 13 above the lower limit wheel 32 to prevent the saw wire 13 above the lower limit wheel 32 from contacting the support shell 3 and causing equipment wear.

[0028] The rotation planes of the upper limit wheel 31, the lower limit wheel 32 and the wire wheel 11 are in the same plane. Therefore, when the support shell 3 swings, the saw wire 13 tilts along the rotation planes of each rotating wheel to avoid friction between the saw wire 13 and the upper limit wheel 31, the lower limit wheel 32 or the side wall of the wire groove of the wire wheel 11.

[0029] In this way, when the PET foam board needs to be cut on an inclined surface, the saw wire 13 is released through the wire storage mechanism 2, and then the angle of the support shell 3 is manually adjusted to make the lower limit wheel 32 at the bottom end of the support shell 3 move in the horizontal direction, and the saw wire 13 is supported by the lower limit wheel 32, so that the saw wire 13 between the lower limit wheel 32 and the cutting table is tilted (such as Figure 3 As shown), until the inclination angle of the saw wire 13 is consistent with the required cutting angle, and then the wire storage mechanism 2 tensions the excess saw wire 13, so that the saw wire 13 between the lower limit wheel 32 and the cutting table is in a taut state. After tensioning the saw wire 13, the power component 12 is turned on to make the saw wire 13 run, and the PET foam board to be cut is clamped by the clamp 5, and the servo slide module 4 is used to drive the PET foam board to move on the cutting table according to the preset cutting path, and the running saw wire 13 is used to cut the PET foam board. At this time, the cutting surface of the PET foam board is an inclined surface.

[0030] It should be noted that the support shell 3 is a rectangular shell with openings at both ends. The saw wire 13 can be introduced through the opening at the top of the support shell 3 and led out through the opening at the bottom of the support shell 3 .

[0031] The support shell 3 of a rectangular shell is used as a mounting platform for the upper limit wheel 31 and the lower limit wheel 32 , so as to protect the upper limit wheel 31 and the lower limit wheel 32 .

[0032] Combination Figure 2 and Figure 6 As shown, a bracket 33 is provided at the top of the support shell 3, a first end of the bracket 33 is connected to the wire storage mechanism 2, and a second end of the bracket 33 is connected to the support shell 3 through a connecting shaft 331, so that the support shell 3 can swing with the connecting shaft 331 as a rotating shaft, and a locking mechanism is provided on the bracket 33. When the swing angle of the support shell 3 is adjusted, the support shell 3 can be locked to keep the support shell 3 in a fixed state, and the lower limit wheel 32 located at the bottom end of the support shell 3 can stably support the saw wire 13 to prevent the saw wire 13 from shaking during the cutting process, thereby ensuring the accuracy of the cutting surface.

[0033] In a specific embodiment, the locking mechanism includes a fixing pin 332 and a mounting hole 302 provided on the bracket 33, the fixing pin 332 is inserted into the mounting hole 302, a plurality of fixing holes 301 corresponding to the mounting hole 302 are provided on the support shell 3, and the plurality of fixing holes 301 are circumferentially distributed with the connecting shaft 331 as the center. When the support shell 3 is swung, the swing radius of the plurality of fixing holes 301 is the same as the center distance between the mounting hole 302 and the connecting shaft 331.

[0034] In this way, when adjusting the swing angle of the support shell 3, the fixing hole 301 corresponding to the angle is swung to correspond to the mounting hole 302, and then the fixing pin 332 is inserted into the mounting hole 302 and the fixing hole 301 in sequence. At this time, the support shell 3 is fixed.

[0035] In an optional embodiment, the fixing hole 301 is an internal threaded hole, and the fixing pin 332 is provided with a corresponding external thread. After the fixing pin 332 passes through the installation hole 302, it is connected to the fixing hole 301 through threads, and the connection is more stable, which can prevent the fixing pin 332 from loosening and slipping.

[0036] Combination Figure 4 As shown, the wire storage mechanism 2 includes a fixed wheel 21, a movable wheel 22 and a lifting component 23. The saw wire 13 passes through the movable wheel 22 and the fixed wheel 21 in sequence. The fixed wheel 21 is connected to the machine table 1 and has a fixed position. The movable wheel 22 is connected to the lifting end of the lifting component 23. The lifting component 23 can drive the movable wheel 22 to rise and fall. When the movable wheel 22 rises, the movable wheel 22 approaches the fixed wheel 21, so that the saw wire 13 between the fixed wheel 21 and the movable wheel 22 is released. When the movable wheel 22 descends, the movable wheel 22 moves away from the fixed wheel 21, so that the saw wire 13 is tensioned.

[0037] Furthermore, the wire storage mechanism 2 also includes a protective shell 24, which is connected to the machine platform 1. The fixed rotating wheel 21, the movable rotating wheel 22 and the lifting component 23 are all arranged in the protective shell 24. The fixed rotating wheel 21 and the movable rotating wheel 22 are protected by the protective shell 24 to improve the safety of the equipment.

[0038] It should be noted that a lead-out tube 25 corresponding to the saw wire 13 is provided at the bottom of the protective shell 24. The saw wire 13 can be led out of the protective shell 24 through the lead-out tube 25, and the supporting shell 3 is located directly below the lead-out tube 25. After the saw wire 13 is led out of the protective shell 24, it can be directly introduced into the supporting shell 3.

[0039] In an optional embodiment, the lifting component 23 adopts one of an electric screw slide, a cylinder, a hydraulic telescopic cylinder, and an electric push rod, and preferably adopts an electric screw slide, which has high transmission accuracy and can accurately control the release length and tension of the saw wire 13.

[0040] Combination Figure 2 and Figure 5 As shown, a delivery pipe 34 is connected to one side of the bottom end of the support shell 3, and an ultrasonic atomizing nozzle 341 is arranged inside the delivery pipe 34. The ultrasonic atomizing nozzle 341 is connected to an external water supply device through a connecting pipe 342, and is used to deliver water mist into the support shell 3. The water mist is gathered by utilizing the sealing performance of the support shell 3 and can be attached to the saw wire 13. When the saw wire 13 contacts the PET foam board for cutting, the water attached to the saw wire 13 can reduce the dust generated by friction cutting. At the same time, the water attached to the saw wire 13 can absorb the heat generated by the friction between the saw wire 13 and the PET foam board, thereby preventing the saw wire 13 from breaking due to excessive temperature.

[0041] Furthermore, an exhaust pipe 35 is connected to one side of the top of the support shell 3, and the exhaust pipe 35 is connected to an external induced draft fan, which can guide the water mist output by the ultrasonic atomizing nozzle 341 to flow toward the top of the support shell 3. The flow direction of the water mist is opposite to the running direction of the saw wire 13. The water mist can be fully attached to the saw wire 13. At the same time, the induced draft fan is used to discharge excess water mist to prevent the water mist from accumulating and dripping down onto the PET foam board.

[0042] Working principle of the present invention: When the PET foam board needs to be cut on an inclined surface, the saw wire 13 is released through the wire storage mechanism 2, and then the angle of the support shell 3 is manually adjusted to make the lower limit wheel 32 at the bottom end of the support shell 3 displace in the horizontal direction, and the saw wire 13 is supported by the lower limit wheel 32, so that the saw wire 13 between the lower limit wheel 32 and the cutting table is tilted (such as Figure 3 The cam 13 is moved upwards to the left of the support shell 3, and then the support shell 3 is locked until the inclination angle of the saw wire 13 is consistent with the required cutting angle. Then, the locking mechanism is used to lock the support shell 3, and the wire storage mechanism 2 is used to tension the excess saw wire 13, so that the saw wire 13 between the lower limit wheel 32 and the cutting table is in a taut state. After tensioning the saw wire 13, the power component 12 is turned on to make the saw wire 13 run, and the PET foam board to be cut is clamped by the clamp 5, and the servo slide module 4 is used to drive the PET foam board to move on the cutting table according to a preset cutting path, and the running saw wire 13 is used to cut the PET foam board. At this time, the cutting surface of the PET foam board is an inclined surface. When normal cutting is required, the support shell 3 is swung to a vertical state, and the wire storage mechanism 2 is used to store and tension the excess saw wire 13. At this time, the saw wire 13 between the lower limit wheel 32 and the cutting table is in a vertical state. When cutting the PET foam board, the cutting surface is a plane. During cutting, the ultrasonic atomizing nozzle 341 is used to deliver water mist to the supporting shell 3, and the sealing performance of the supporting shell 3 is used to gather the water mist and attach it to the saw wire 13. When the saw wire 13 contacts the PET foam board for cutting, the water attached to the saw wire 13 can reduce the dust generated by friction cutting. At the same time, the water attached to the saw wire 13 can absorb the heat generated by the friction between the saw wire 13 and the PET foam board to prevent the saw wire 13 from breaking due to excessive temperature. At the same time, the external induced draft fan draws the gas inside the supporting shell 3 through the exhaust pipe 35, and uses suction to guide the water mist output by the ultrasonic atomizing nozzle 341 to flow toward the top of the supporting shell 3. The flow direction of the water mist is opposite to the running direction of the saw wire 13, and the water mist can fully attach to the saw wire 13. At the same time, the induced draft fan is used to discharge excess water mist to prevent the water mist from accumulating and dripping down onto the PET foam board.

[0043] In summary of the above embodiments: by providing an upper limit wheel 31 and a lower limit wheel 32 that can move horizontally, and using the lower limit wheel 32 to support the saw wire 13, by adjusting the position of the lower limit wheel 32, the saw wire 13 between the lower limit wheel 32 and the cutting table is tilted. At this time, the cutting surface formed by the saw wire 13 cutting the PET foam board is an inclined surface, thereby realizing inclined surface cutting; A rectangular shell support shell 3 is used as an installation platform for the upper limit wheel 31 and the lower limit wheel 32, and an ultrasonic atomizing nozzle 341 is arranged on the support shell 3 to transport water mist into the support shell 3. The sealing performance of the support shell 3 is utilized to gather the water mist so that the water mist can better adhere to the saw wire 13. When the saw wire 13 contacts the PET foam board for cutting, the water attached to the saw wire 13 can reduce the dust generated by friction cutting. At the same time, the water attached to the saw wire 13 can absorb the heat generated by the friction between the saw wire 13 and the PET foam board, thereby preventing the saw wire 13 from breaking due to excessive temperature.
