[0003] Patent CN216264105U discloses a dust collection device for laser cutting equipment. This device includes an air pump, an air nozzle, an air jet nozzle, an inner dust collection hood, an outer dust collection hood, a fixing ring, and an air jet pump. A fixing ring is installed at the upper end of the laser head. The inner dust collection hood is installed behind the fixing ring via a connecting rod. The inner dust collection hood is designed to be enclosed on three sides and open on one side. An air jet nozzle is installed in front of the fixing ring via a support rod, located on the open side of the inner dust collection hood. An air nozzle is installed on the inner wall of the inner dust collection hood via a support platform. The outer dust collection hood is installed on the outer wall of the inner dust collection hood via a mounting plate, which also has an air nozzle installed. This patent provides a dust collection device for laser cutting equipment that collects dust through blowing and suction, making the collection simple and effective, thus preventing dust from flying and affecting the working environment, reducing environmental pollution, and avoiding impacts on the health of production workers.

[0004] During the cutting process of the sewing machine casing, the laser head emits a high-energy beam to cut the casing. The laser head vibrates during the cutting process, which leads to inaccurate cutting by the high-energy beam. At the same time, the laser head generates a lot of heat on its surface during the cutting process, which can cause the laser head to overheat and be damaged. Furthermore, the ring frame bears the weight of the laser head during its movement. When the equipment is started, the ring frame is not supported and is prone to sliding and jamming due to inertia. Summary of the Invention

The two springs are sleeved on the outside of the guide rod, and the elastic force when the springs are compressed or extended reduces the vibration when the laser head cuts the sewing machine housing.

[0010] In one possible implementation, the two electrically controlled slides are located on the left and right sides of the shell frame, the laser head is located above the shell frame, the laser head is positioned below the long shell, and the guide rod is located below the screw.

[0011] In one possible implementation, a cooling device is provided on the lower left and right sides of the I-shaped tube, the cooling device being used to cool the laser head during operation, and an anti-jamming device is provided on the inner wall of the through hole of the ring vertical frame, the anti-jamming device being used to support the reciprocating left and right movement of the ring vertical frame.

[0012] In one possible implementation, the cooling device includes: two L-shaped plates, which are fixed below the left and right sides of the I-shaped tube, and the two L-shaped plates are located inside the groove of the long shell; The recessed boxes are respectively fixed on the sides of the two L-shaped plates that are close to each other; A copper pipe is inserted through and fixed to the inner wall of two concave boxes. The left end of the copper pipe has a water inlet and the right end has a drain outlet. The concave boxes drive the copper pipe to move back and forth. A heat-conducting plate is fixed on one side of two concave boxes that are close to each other. The heat-conducting plate is attached to the left and right sides of the laser head. The concave boxes drive the heat-conducting plate to move back and forth. The heat-conducting plate absorbs the heat generated during laser head operation, while the cold water circulating in the copper pipe carries away the heat from the heat-conducting plate.

[0013] In one possible implementation, a connecting plate is fixed to the side of each of the two L-shaped plates that are far apart from each other, and an inclined plate is fixed to the side of each of the two connecting plates that are far apart from each other. The connecting plate drives the inclined plate to move back and forth left and right. A chamfered frame is fixed to the bottom surface of each of the two inclined plates, and the inclined plate drives the chamfered frame to move back and forth left and right.

[0014] In one possible implementation, the anti-jamming device includes: a U-shaped rod fixed to the inner wall of the through hole of the ring vertical frame; The U-shaped frame is fixed to the left and right sides of the inner wall of the long shell, and the U-shaped frame is located above the screw.

A thin tube is passed through and fixed to the inner wall of each of the two oil grooves. The horizontal block drives the thin tube to move back and forth. The outer walls of the two thin tubes are fixedly connected to the inner walls of the two small holes of the ring vertical frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention uses a base, shell frame, electrically controlled slide, column frame, long shell, screw, servo motor, ring vertical frame, laser head, I-shaped tube, short column and guide rod with spring. The electrically controlled slide drives the column frame to move back and forth, the column frame drives the long shell to move back and forth, and under the restriction of the slide groove of the long shell, the ring vertical frame moves left and right in the thread groove of the screw. The ring vertical frame drives the laser head to move left and right, so that the laser head automatically moves to cut the sewing machine shell. The ring vertical frame drives the I-shaped tube to move left and right, and the I-shaped tube slides left and right on the surface of the guide rod. The I-shaped tube stretches and compresses the spring. Under the action of the spring, the spring buffers the ring vertical frame to prevent the laser head from shaking when moving and cutting, which would cause the high-energy beam emitted by the laser head to cut inaccurately.

[0017] (2) By setting up a cooling device, the L-shaped plate, the concave box and the copper tube work together with the heat-conducting plate. The concave box drives the copper tube to move back and forth, and the concave box drives the heat-conducting plate to move back and forth. The heat-conducting plate absorbs the heat on the laser head, and the cold water flowing in the copper tube carries away the heat on the heat-conducting plate, preventing the laser head from moving and cutting, and preventing the laser head from generating high heat on the surface of the laser head, which would cause the laser head to overheat and be damaged.

[0018] (3) By setting a cooling device, the present invention enables the connecting plate and the inclined plate to cooperate with the chamfered frame. The connecting plate drives the inclined plate to move back and forth left and right, and the inclined plate drives the chamfered frame to move back and forth left and right. The chamfered frame slides in the long shell groove, preventing impurities from accumulating in the long shell groove and causing the ring vertical frame to slide unsmoothly.

[0019] (4) By setting up an anti-jamming device, the U-shaped rod, U-shaped frame and ring horizontal plate cooperate with the roller. The ring horizontal plate drives the roller to move back and forth left and right. The roller rolls back and forth left and right on the U-shaped frame. The roller supports the ring vertical frame to move back and forth left and right, preventing the ring vertical frame from sliding and jamming due to the weight of the laser head when it moves.

[0020] (5) By setting an anti-jamming device, the present invention enables the horizontal block and the oil tank to cooperate with the thin tube. The horizontal block drives the thin tube to move back and forth. The lubricating oil in the oil tank flows into the thin tube, and the thin tube delivers the lubricating oil to the ring vertical frame, preventing the screw surface from aging and rusting, which would cause the ring vertical frame to have poor laser head movement effect.

[0023] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0024] like Figure 1-8 As shown, one embodiment of the present invention is: a cutting device for a sewing machine casing, comprising: a base 1, a casing frame 2 provided on the top surface of the base 1, and the top surface of the casing frame 2 being used to place the sewing machine casing; Two electrically controlled slides 3 are provided on the top surface of the base 1. The two electrically controlled slides 3 are located on the left and right sides of the shell frame 2. The electrically controlled slides 3 include: a frame plate 301, a threaded rod 302, a second servo motor 303, and a platform 304. A sliding groove is provided in the lower interior of the frame plate 301.

A column frame 4 is provided on the top surface of each of the two electrically controlled slides 3. The top surface of the platform 304 is fixedly connected to the bottom surface of the column frame 4. The long shell 5 is fixed to the top surface of the two column frames 4, and a sliding groove is provided at the bottom of the interior of the long shell 5. Screw 6 is rotatably mounted on the inner wall of the long shell 5, and a non-self-locking threaded groove is provided on the outer wall of screw 6; Servo motor 7 is located on the left side of the long shell 5, and the right end of the output shaft of servo motor 7 is fixedly connected to the left end of screw 6. The ring vertical bracket 8 is slidably installed on the outer wall of the screw 6. The outer wall of the ring vertical bracket 8 is slidably connected to the inner wall of the sliding groove of the long shell 5. The inner wall of the ring vertical bracket 8 is engaged with the outer wall of the threaded groove of the screw 6. A through hole is opened on the front of the ring vertical bracket 8, and two small holes are provided on the upper front of the ring vertical bracket 8. Laser head 9 is located on the bottom surface of the ring vertical frame 8, above the shell frame 2, and below the long shell 5. I-shaped tube 10, which is fixed to the inner wall of the ring vertical frame 8; Two short pillars 11 are fixed to the left and right sides of the inner wall of the long shell 5. Guide rod 12 is fixed at one end of two short columns 11 that are close to each other. The outer wall of guide rod 12 is in sliding contact with the inner wall of I-shaped tube 10. Guide rod 12 is located below screw 6. Two springs 13 are fixed between the two short columns 11 on the side that are close to each other and the left and right sides of the I-shaped tube 10. The two springs 13 are sleeved on the outside of the guide rod 12. The elastic force of the springs 13 when they are compressed or extended reduces the vibration of the laser head 9 when cutting the sewing machine housing. When using this cutting device, the base platform 1 supports the shell frame 2. The operator places the sewing machine housing on the shell frame 2 and starts the electronically controlled slide table 3 via the computer terminal. The output shaft of servo motor 2 303 begins to rotate in both directions. The output shaft of servo motor 2 303 drives the threaded rod 302 to rotate in both directions. The threaded rod 302 rotates in both directions within the frame plate 301. Under the constraint of the sliding groove of the frame plate 301, the platform 304 slides back and forth in the threaded groove of the threaded rod 302. The platform 304 moves back and forth within the sliding groove of the frame plate 301. The platform 304 drives the column frame 4 to move back and forth. The column frame 4 drives the long shell 5 to move back and forth. The long shell 5 drives the screw 6 to move back and forth. The screw 6 drives the ring vertical frame 8 to move back and forth. The ring vertical frame 8 drives the laser head 9 to move back and forth. At the same time, the computer terminal starts servo motor 1 7, and the output shaft of servo motor 1 7 begins to rotate in both directions. Servo motor 1 7 drives the screw 6 to move in both directions. The screw 6 rotates back and forth within the long shell 5. Constrained by the groove of the long shell 5, the ring vertical frame 8 moves left and right within the threaded groove of the screw 6. The ring vertical frame 8 drives the laser head 9 to move left and right, causing the laser head 9 to automatically move and cut the sewing machine casing. Simultaneously, the ring vertical frame 8 drives the I-shaped tube 10 to move left and right, which in turn drives the spring 13 to move left and right. The long shell 5 supports the short column 11, which in turn supports the guide rod 12. The I-shaped tube 10 slides left and right on the surface of the guide rod 12, repeatedly stretching and compressing the spring 13. Under the elastic force of the spring 13, the spring 13 buffers the ring vertical frame 8. Through the damping of the groove of the long shell 5, the vibration of the laser head 9 during cutting is reduced, thus avoiding the problem of inaccurate cutting of the high-energy beam emitted by the laser head 9 due to vibration during the cutting process of the sewing machine casing.

[0025] Cooling devices 14 are provided on the lower left and right sides of the I-shaped tube 10. Cooling devices 14 are used to cool the laser head 9 during operation. Anti-jamming devices 15 are provided on the inner wall of the through hole of the ring vertical frame 8. Anti-jamming devices 15 are used to support the reciprocating movement of the ring vertical frame 8.

[0026] Working principle: The sewing machine housing is placed on the shell frame 2. The electric control slide 3 drives the column frame 4 to move back and forth, and the column frame 4 drives the long shell 5 to move back and forth. The servo motor 7 drives the screw 6 to rotate in both directions. Under the constraint of the sliding groove of the long shell 5, the ring vertical frame 8 moves left and right in the threaded groove of the screw 6. The ring vertical frame 8 moves left and right in the sliding groove of the long shell 5. The ring vertical frame 8 drives the laser head 9 to move left and right, so that the laser head 9 automatically moves to cut the sewing machine housing. The ring vertical frame 8 drives the I-shaped tube 10 to move left and right. The I-shaped tube 10 drives the spring 13 to move left and right. The I-shaped tube 10 slides left and right on the surface of the guide rod 12. The I-shaped tube 10 stretches and compresses the spring 13. Under the elastic force of the spring 13, the spring 13 buffers the ring vertical frame 8.

[0027] like Figure 1-8 As shown, based on the above embodiments, in another embodiment of the present invention, the cooling device 14 includes: two L-shaped plates 141, which are fixed below the left and right sides of the I-shaped tube 10, and the two L-shaped plates 141 are located inside the sliding groove of the long shell 5. The recessed box 142 is fixed on one side of the two L-shaped plates 141 that are close to each other. A copper pipe 143 is inserted through and fixed to the inner wall of two concave boxes 142. A water inlet is provided at the left end of the copper pipe 143 and a drain outlet is provided at the right end of the copper pipe 143. Heat-conducting plate 144 is fixed on one side of the two concave boxes 142 that are close to each other, and heat-conducting plate 144 is attached to the left and right sides of laser head 9. The heat-conducting plate 144 absorbs the heat from the laser head 9 during operation, and the cold water circulating in the copper pipe 143 carries away the heat from the heat-conducting plate 144. The operator connects a circulating water pump to the inlet and outlet of the copper pipe 143. While the ring vertical frame 8 drives the I-shaped pipe 10 to move back and forth, the I-shaped pipe 10 drives the L-shaped plate 141 to move back and forth, the L-shaped plate 141 drives the concave box 142 to move back and forth, the concave box 142 drives the copper pipe 143 to move back and forth, and the concave box 142 drives the heat-conducting plate 144 to move back and forth. The heat-conducting plate 144 absorbs the heat from the laser head 9, and the cold water flowing in the copper pipe 143 carries away the heat from the heat-conducting plate 144. This avoids the problem of the laser head 9 overheating and being damaged when it moves and cuts during the cutting process of the sewing machine casing.

[0028] A connecting plate 145 is fixed to one side of each of the two L-shaped plates 141 that are far apart from each other. A sloping plate 146 is fixed to one side of each of the two connecting plates 145 that are far apart from each other. A chamfered frame 147 is fixed to the bottom surface of each of the two sloping plates 146. While the L-shaped plate 141 drives the concave box 142 to move back and forth, the L-shaped plate 141 drives the connecting plate 145 to move back and forth, the connecting plate 145 drives the inclined plate 146 to move back and forth, and the inclined plate 146 drives the chamfering frame 147 to move back and forth. The chamfering frame 147 scrapes away impurities such as metal powder, slag lubricating oil and dust accumulated in the groove of the long shell 5, thereby avoiding the problem of the ring vertical frame 8 not sliding smoothly due to impurities accumulating in the groove of the long shell 5 during the cutting process of the sewing machine shell.

[0029] The anti-jamming device 15 includes: a U-shaped rod 151, which is fixed to the inner wall of the through hole of the ring vertical frame 8; U-shaped frame 152 is fixed on the left and right sides of the inner wall of the long shell 5, and the U-shaped frame 152 is located above the screw 6; Two ring-shaped horizontal plates 153 are fixed to the outer wall of the U-shaped rod 151; Rollers 154 are installed in pairs on the side of the two ring horizontal plates 153 that are close to each other. The outer wall of the roller 154 rolls in contact with the bottom of the U-shaped frame 152. The left and right reciprocating rolling of the roller 154 supports the left and right reciprocating movement of the ring vertical frame 8. While the vertical ring frame 8 drives the I-shaped tube 10 to move back and forth, the vertical ring frame 8 drives the U-shaped rod 151 to move back and forth, the U-shaped rod 151 drives the horizontal ring plate 153 to move back and forth, the horizontal ring plate 153 drives the roller 154 to move back and forth, the roller 154 rolls back and forth on the U-shaped frame 152, and the roller 154 supports the vertical ring frame 8 to move back and forth, thus avoiding the problem of the vertical ring frame 8 sliding and getting stuck due to inertia when it bears the weight of the laser head 9 during the cutting process of the sewing machine casing.

[0030] A horizontal block 155 is fixed to the outer wall of the U-shaped rod 151. Two oil grooves 156 are opened on the top surface of the horizontal block 155. A thin tube 157 is passed through and fixed to the inner wall of each of the two oil grooves 156. The outer wall of the two thin tubes 157 is fixedly connected to the inner wall of the two thin holes of the ring vertical frame 8. While the U-shaped rod 151 drives the ring horizontal plate 153 to move back and forth, the U-shaped rod 151 drives the horizontal block 155 to move back and forth, and the horizontal block 155 drives the thin tube 157 to move back and forth. The lubricating oil in the oil groove 156 flows into the thin tube 157, and the thin tube 157 delivers the lubricating oil to the ring vertical frame 8. The lubricating oil inside the ring vertical frame 8 lubricates the thread groove of the screw 6, thereby avoiding the problem that the surface of the screw 6 is aged and corroded during the cutting process of the sewing machine housing, which causes the ring vertical frame 8 to have poor movement effect of supporting the laser head 9.

[0031] Working principle: Connect a circulating water pump to the inlet and outlet of copper pipe 143. I-shaped pipe 10 drives L-shaped plate 141 to move back and forth left and right. L-shaped plate 141 drives concave box 142 to move back and forth left and right. Concave box 142 drives copper pipe 143 to move back and forth left and right. Concave box 142 drives heat conduction plate 144 to move back and forth left and right. L-shaped plate 141 drives connecting plate 145 to move back and forth left and right, connecting plate 145 drives inclined plate 146 to move back and forth left and right, inclined plate 146 drives chamfer frame 147 to move back and forth left and right. The vertical ring 8 drives the U-shaped rod 151 to move back and forth left and right. The U-shaped rod 151 drives the horizontal ring 153 to move back and forth left and right. The horizontal ring 153 drives the roller 154 to move back and forth left and right. The roller 154 rolls back and forth left and right on the U-shaped frame 152. U-shaped rod 151 drives horizontal block 155 to move back and forth, and horizontal block 155 drives thin tube 157 to move back and forth.
