A second mounting tube 38 is provided at one end of the inner expansion shaft body 32 away from the first mounting tube 25. A suction cup 15 communicating with the inner expansion shaft body 32 is provided at one end of the second mounting tube 38 away from the outer expansion shaft body 24. A push plate 40 connected to the hollow seat 45 is provided inside the first mounting tube 25, and a chamber 251 is formed between the push plate 40 and the inner wall of the first mounting tube 25. At the same time, in the process of die-cutting the die-cutting raw materials, by adjusting another expansion shaft perpendicular to the upper surface of the base, when the first through hole opened on the circumferential outer wall of the inner expansion shaft body is rotated to be misaligned with the second through hole opened on the circumferential outer wall of the outer expansion shaft body, the second through hole opened on the circumferential outer wall of the outer expansion shaft body is closed by the inner expansion shaft body. When the die-cutting raw materials need to be die-cut during the transmission process, by connecting the die-cutting part and the vacuum equipment, the vacuum suction cup at one end of the inner expansion shaft body can be used to vacuum adsorb the lower surface of the die-cutting raw materials, thereby ensuring the stability of the die-cutting raw materials during the die-cutting process.

[0021] A coil spring 34 is provided on the outer wall of the second mounting tube 38, one end of the coil spring 34 is fixedly connected to the outer wall of the second mounting tube 38, and the other end is connected to the inner wall of the outer expansion shaft body 24. When the coil spring 34 is in a natural state, the first through hole 33 and the second through hole 35 overlap, so that the expansion head 41 can pass through the first through hole 33 and the second through hole 35 and extend out.

[0022] An extrusion rod 14 is disposed on the second mounting tube 38 and located outside the outer expansion shaft body 24, and a vertical rod 19 for pushing the extrusion rod 14 is disposed at the bottom of the connecting plate 18, so that the inner expansion shaft body 32 and the outer expansion shaft body 24 rotate relative to each other; By providing a connecting rod, the lateral movement of the hollow seat can be converted into a linear movement of the mounting block along the circumferential outer wall of the limit rod. When the internal expansion reel needs to be supported by the internal expansion method, the expansion head can pass through the first through hole and the second through hole in sequence under the driving action of the mounting block, and finally be supported on the inner surface of the internal expansion reel. By providing a magnet, the push plate can be adsorbed on the circumferential inner wall of the first mounting tube after moving to a set position along the circumferential inner wall of the first mounting tube, thereby limiting the position of the expansion head and ensuring the stability of the expansion head when expanding the internal expansion reel. When the die-cutting raw material of the circumferential outer wall of the internal expansion reel is completed and the internal expansion reel needs to be replaced, the magnet is powered off, so that the expansion head can automatically reset under the elastic force of the spring, which is convenient for subsequent periodic internal expansion support of the internal expansion reel.

[0023] A vertical plate 8 with an air cylinder 6 on the upper end is fixedly installed on the top of the above-mentioned base 1, and the end of the above-mentioned transverse rod 51 away from the pad 27 can be extended into the interior of the air cylinder 6 and is fixedly connected with a piston plate 50, and one end of the above-mentioned air cylinder 6 is connected to one of the chambers 251 through a first hose 7, and the other end is connected to the other chamber 251 through a second hose 17.

[0024] A cushion block 27 is installed at one end of the traverse rod 51 and the guide rod 12, a gear 26 is installed on one side of the cushion block 27, and an annular hoop 30 is installed on the outer wall of the first mounting tube 25 on the other side, and the gear 26 and the annular hoop 30 are fixedly connected by an intermediate rod 31, and the intermediate rod 31 is rotatably connected to the cushion block 27; A driving motor is provided to drive the toggle plate to rotate, and the first waist-shaped hole and the second waist-shaped hole on the surface of the toggle plate are respectively adapted to the two driving rods, so that during the rotation of the toggle plate, the first waist-shaped hole and the second waist-shaped hole on the surface of the toggle plate can be used to convert the circular motion of the toggle plate into the lateral linear motion of the two expansion shafts, and the movement directions of the two expansion shafts are opposite.

[0025] The driving mechanism comprises: a suspension rod 16, a driving rod 28 installed at the bottom of a cushion block 27, and a toggle plate 47 having a first waist-shaped hole 21 and a second waist-shaped hole 22. A driving motor 49 is arranged between the two vertical plates 8 and on the top of the base 1, and the output shaft of the driving motor 49 is fixedly connected to the toggle plate 47. The first waist-shaped hole 21 and the second waist-shaped hole 22 are symmetrically distributed about the output shaft of the driving motor 49. One of the cushion blocks 27 and the first waist-shaped hole 21 and the other cushion block 27 and the second waist-shaped hole 22 are connected respectively through the driving rod 28. The suspension rod 16 with a rack 13 installed at the bottom is fixedly connected to the die-cutting plate 3, and the rack 13 is meshedly connected to the gear 26. By providing the rack and the gear, when the two expansion shafts perform linear motion in the lateral direction, when one of the expansion shafts is gradually rotated to be perpendicular to the upper surface of the base under the driving action of the rack and the gear, the other expansion shaft can be gradually rotated to be parallel to the upper surface of the base under the driving action of the rack and the gear.

[0026] A magnet 39 is fixed to the outer wall of one side of the push plate 40 , and an electromagnet 36 cooperating with the magnet 39 is arranged on the outer wall of the first mounting tube 25 .

[0027] A bracket 4 with a cylinder 10 installed is arranged on the top of the die-cutting plate 3 , and the movable shaft of the cylinder 10 is fixedly connected to the die-cutting knife 11 .

[0028] The die-cutting board 3 is fixedly mounted on the top of the base 1 through a plurality of vertical rods 2 .

[0029] The vertical rods 2 are respectively installed at the bottom corners of the die-cutting board 3 .

[0030] The extrusion rod 14 is threadedly connected to the outer wall of the second mounting tube 38 .

[0031] Embodiment 2: An expansion shaft die-cutting machine, comprising: a base 1, a die-cutting plate 3 with a hollow area 301 is arranged above the base 1, a connecting plate 18 is arranged at the inner interval of the hollow area 301, and a die-cutting knife 11 is arranged between the two connecting plates 18; a first guide plate 9 with a lateral rod 51 slidably connected to the upper end and a second guide plate 20 with a guide rod 12 slidably connected to the upper end are fixedly installed on the top of the base 1, and the lateral rod 51 and the guide rod 12 are both connected to an expansion shaft mechanism, and a driving mechanism is arranged between the die-cutting plate 3 and the base 1, so that one of the expansion shaft mechanisms is in a vertical state while the other is in a horizontal state; When one of the expansion shafts is being operated, the material can be installed on the other expansion shaft through the hollow area, thereby saving the time of disassembly and installation of the material and improving the overall production efficiency.

[0032] The expansion shaft mechanism comprises: an outer expansion shaft body 24 having a first mounting tube 25 at one end, an inner expansion shaft body 32 having a plurality of first through holes 33 formed in the circumferential outer wall, a plurality of mounting blocks 42 being arranged inside the outer expansion shaft body 24 having a plurality of second through holes 35 formed in the circumferential side wall, and a plurality of expansion heads 41 being arranged at intervals along the length direction of the mounting block 42, a limiting rod 43 for movably fitting the mounting block 42 being fixedly mounted on the inner wall of the outer expansion shaft body 24, and a spring 46 being arranged between the ends of the mounting block 42 and the limiting rod 43, and a hollow seat 45 movably connected to the connecting rod 44 being movably connected inside the first mounting tube 25; One of the expansion shaft mechanisms is in a horizontal state, and the hollow seat inside the expansion shaft mechanism moves toward the inside of the expansion shaft body, so that the connecting rod movably connected to the hollow seat pushes the mounting block to slide along the limit rod, so that the expansion head extends through the second through hole, thereby supporting and fixing the material outside the external expansion shaft body. The loss of support and fixation for the material makes it easier for personnel to replace the material, greatly improving the convenience of personnel operation; The inner expansion shaft body 32 is fitted and sleeved inside the outer expansion shaft body 24. A second mounting tube 38 is provided at one end of the inner expansion shaft body 32 away from the first mounting tube 25. A suction cup 15 communicating with the inner expansion shaft body 32 is provided at one end of the second mounting tube 38 away from the outer expansion shaft body 24. A push plate 40 connected to the hollow seat 45 is provided inside the first mounting tube 25, and a chamber 251 is formed between the push plate 40 and the inner wall of the first mounting tube 25. The other expansion shaft mechanism is in a vertical state, and the hollow seat inside the expansion shaft mechanism moves away from the inside of the outer expansion shaft body, and under the tension of the spring, the mounting block is driven to move in the axial direction of the outer expansion shaft body, so that the expansion head shrinks from the second through hole, and in this process, the inner expansion shaft body and the outer expansion shaft body rotate relatively, so that the first through hole and the second through hole are staggered, thereby forming a confined space between the inner expansion shaft body and the outer expansion shaft body in the vertical state, and during the movement of the push plate, the confined space forms a negative pressure environment, which is conducive to the adsorption of materials and improves the stability of material movement.

[0033] A coil spring 34 is disposed on the outer wall of the second mounting tube 38. One end of the coil spring 34 is fixedly connected to the outer wall of the second mounting tube 38, and the other end is connected to the inner wall of the outer expansion shaft body 24. When the coil spring 34 is in a natural state, the first through hole 33 and the second through hole 35 overlap, so that the expansion head 41 can pass through the first through hole 33 and the second through hole 35 and extend out. The connection of the coil spring can play a positioning role between the outer expansion shaft body and the inner expansion shaft body in the initial stage, thereby ensuring that the first through hole opened on the circumferential outer wall of the inner expansion shaft body can overlap with the second through hole opened on the circumferential outer wall of the outer expansion shaft body. When the expansion shaft rotates under the drive of the rack and the gear, when the extrusion rod gradually rotates to the vertical rod, the vertical rod will block and limit the extrusion rod, thereby limiting the movement of the inner expansion shaft body. Therefore, when the outer expansion shaft body continues to move, the vertical rod blocks the extrusion rod to enable the outer expansion shaft body and the inner expansion shaft body to rotate relative to each other.

[0034] An extrusion rod 14 is disposed on the second mounting tube 38 and located outside the outer expansion shaft body 24, and a vertical rod 19 for pushing the extrusion rod 14 is disposed at the bottom of the connecting plate 18, so that the inner expansion shaft body 32 and the outer expansion shaft body 24 rotate relative to each other; During this process, the coil spring begins to produce elastic deformation. The ultimate goal is that when the expansion shaft rotates to be perpendicular to the upper surface of the base, the first through hole opened on the circumferential outer wall of the inner expansion shaft body and the second through hole opened on the circumferential outer wall of the outer expansion shaft body are automatically misaligned, ensuring that when the vacuum suction cup is used to adsorb and fix the lower surface of the die-cutting raw material in the future, gas leakage is avoided. When the two expansion shafts need to switch their postures, the elastic effect of the coil spring is used to quickly reset the inner expansion shaft body relative to the outer expansion shaft body.

[0035] A vertical plate 8 with an air cylinder 6 on the upper end is fixedly installed on the top of the above-mentioned base 1, and the end of the above-mentioned transverse rod 51 away from the pad 27 can be extended into the interior of the air cylinder 6 and is fixedly connected with a piston plate 50, and one end of the above-mentioned air cylinder 6 is connected to one of the chambers 251 through a first hose 7, and the other end is connected to the other chamber 251 through a second hose 17.

[0036] A cushion block 27 is installed at one end of the traverse rod 51 and the guide rod 12, a gear 26 is installed on one side of the cushion block 27, and an annular hoop 30 is installed on the outer wall of the first mounting tube 25 on the other side, and the gear 26 and the annular hoop 30 are fixedly connected by an intermediate rod 31, and the intermediate rod 31 is rotatably connected to the cushion block 27; By fixing the piston plate on the circumferential outer wall of the transverse rod, the piston plate can be driven to slide along the circumferential inner wall of the cylinder when the transverse rod moves horizontally. The piston plate divides the interior of the cylinder into two left and right chambers. The piston plate can ensure that the gas in one of the chambers is squeezed during the movement, so that the air pressure in the other chamber is increased, so that the gas can be introduced into the first mounting tube through the first hose or the second hose. The push plate can be squeezed by the pushing effect of the gas, thereby automatically realizing the lateral movement of the hollow seat and realizing automatic adjustment of the expansion head assembly. When the expansion head assembly is adjusted to the set state, the magnet is adsorbed on the circumferential inner wall of the first mounting tube to limit the expansion head assembly, and then the electromagnet is turned on, so that the excess gas can be discharged through the electromagnet in time to avoid damage to the inner expansion drum caused by excessive deformation of the expansion head assembly.

[0037] The above-mentioned driving mechanism includes: a suspension rod 16, a driving rod 28 installed at the bottom of the pad 27, and a toggle plate 47 with a first waist-shaped hole 21 and a second waist-shaped hole 22. A driving motor 49 is arranged between the two vertical plates 8 and on the top of the above-mentioned base 1, and the output shaft of the driving motor 49 is fixedly connected to the toggle plate 47, and the above-mentioned first waist-shaped hole 21 and the second waist-shaped hole 22 are symmetrically distributed about the output axis of the driving motor 49. One of the above-mentioned pads 27 and the first waist-shaped hole 21 and the other above-mentioned pad 27 and the second waist-shaped hole 22 are respectively connected by the driving rod 28. The above-mentioned suspension rod 16 with a rack 13 installed at the bottom is fixedly connected to the die-cutting plate 3, and the above-mentioned rack 13 is meshed with the gear 26.

[0038] A magnet 39 is fixed to the outer wall of one side of the push plate 40 , and an electromagnet 36 cooperating with the magnet 39 is arranged on the outer wall of the first mounting tube 25 .

[0040] An air bag 23 is arranged on one side of the bracket 4 and above the hollow area 301, an electromagnetic valve 36 is arranged on the side wall of the mounting ring 25, and an inflation tube 5 is arranged between the air bag 23 and the electromagnetic valve 36; During this process, the piston plate evacuates gas from another chamber, and the gas can be drawn into the first installation tube through the electromagnet under the action of negative pressure to replenish the gas; The airbag and the electromagnet are connected by a hose, so that when the electromagnet is turned on, excess gas can be introduced into the airbag through the electromagnet. The airbag gradually expands after the air is taken in, so that the airbag can exert a certain pressure on the upper surface of the die-cutting raw material. The airbag can play a smoothing role in the process of conveying the die-cutting raw materials, which can effectively avoid wrinkles on the surface of the die-cutting raw materials, thereby ensuring the flatness of the die-cutting raw materials during die-cutting.

[0041] The working principle is: The toggle plate can be driven to rotate by providing a driving motor, and the first waist-shaped hole and the second waist-shaped hole on the surface of the toggle plate are respectively adapted to the two driving rods, so that during the rotation of the toggle plate, the first waist-shaped hole and the second waist-shaped hole on the surface of the toggle plate can be used to convert the circular motion of the toggle plate into the lateral linear motion of the two expansion shafts, and the movement directions of the two expansion shafts are opposite; By providing a rack and a gear, when the two expansion shafts move linearly in the horizontal direction, when one of the expansion shafts is gradually rotated to be perpendicular to the upper surface of the base under the driving action of the rack and the gear, the other expansion shaft can be gradually rotated to be parallel to the upper surface of the base under the driving action of the rack and the gear; When it is necessary to perform die-cutting on the die-cutting raw material, the expansion shaft parallel to the upper surface of the base is adjusted so that the first through hole opened on the circumferential outer wall of the inner expansion shaft body is rotated to overlap with the second through hole opened on the circumferential outer wall of the outer expansion shaft body, so that the expansion head arranged inside the inner expansion shaft body is led out through the first through hole and the second through hole, so that the inner expansion reel can be supported by the inner expansion method, thereby ensuring the stability between the inner expansion reel and the circumferential outer wall of the outer expansion shaft body, so that the outer expansion shaft body can unwind the die-cutting raw material during the rotation process, thereby facilitating the subsequent die-cutting of the die-cutting raw material; At the same time, in the process of die-cutting the die-cutting raw material, by adjusting another expansion shaft perpendicular to the upper surface of the base, when the first through hole opened on the circumferential outer wall of the inner expansion shaft body is rotated to be misaligned with the second through hole opened on the circumferential outer wall of the outer expansion shaft body, the second through hole opened on the circumferential outer wall of the outer expansion shaft body is closed by the inner expansion shaft body. When the die-cutting raw material needs to be die-cut during the transmission process, by connecting the die-cutting part and the vacuum equipment, the vacuum suction cup at one end of the inner expansion shaft body can be used to vacuum adsorb the lower surface of the die-cutting raw material, thereby ensuring the stability of the die-cutting raw material during the die-cutting process. The connection of the coil spring can play a positioning role between the outer expansion shaft body and the inner expansion shaft body in the initial stage, thereby ensuring that the first through hole opened on the circumferential outer wall of the inner expansion shaft body can overlap with the second through hole opened on the circumferential outer wall of the outer expansion shaft body. When the expansion shaft rotates under the driving action of the rack and the gear, when the extrusion rod gradually rotates to the vertical rod, the vertical rod will play a blocking and limiting role on the extrusion rod, thereby limiting the movement of the inner expansion shaft body. Therefore, when the outer expansion shaft body continues to move, the vertical rod is used to block the extrusion rod so that the outer expansion shaft body can be The shaft body and the inner expansion shaft body rotate relative to each other, and the coil spring begins to produce elastic deformation during this process. The ultimate goal is that when the expansion shaft rotates to be perpendicular to the upper surface of the base, the first through hole opened on the circumferential outer wall of the inner expansion shaft body and the second through hole opened on the circumferential outer wall of the outer expansion shaft body are automatically misaligned, so as to ensure that when the vacuum suction cup is used to adsorb and fix the lower surface of the die-cutting raw material in the future, gas leakage is avoided. When the two expansion shafts need to switch their postures, the elastic effect of the coil spring is used to quickly reset the inner expansion shaft body relative to the outer expansion shaft body. By providing a connecting rod, the lateral movement of the hollow seat can be converted into a linear movement of the mounting block along the circumferential outer wall of the limiting rod. When the inner expansion reel needs to be supported by the inner expansion method, the expansion head can pass through the first through hole and the second through hole in sequence under the driving action of the mounting block, and finally be supported on the inner surface of the inner expansion reel. By providing a magnet, the push plate can be adsorbed on the circumferential inner wall of the first mounting tube after moving to a set position along the circumferential inner wall of the first mounting tube, thereby limiting the position of the expansion head and ensuring the stability of the expansion head when the expansion reel is expanded internally. When the die-cutting raw material of the circumferential outer wall of the inner expansion reel is completed and the inner expansion reel needs to be replaced, the magnet is powered off, so that the expansion head can automatically reset under the elastic force of the spring, which is convenient for subsequent periodic internal expansion support of the inner expansion reel. The cylinder can be provided to drive the die-cutting head to perform die-cutting operation on the surface of the die-cutting raw material during the downward movement; By fixing the piston plate on the circumferential outer wall of the transverse rod, the piston plate can be driven to slide along the circumferential inner wall of the cylinder when the transverse rod moves horizontally. The piston plate divides the interior of the cylinder into two left and right chambers. The piston plate can ensure that the gas in one of the chambers is squeezed during the movement, so that the air pressure in the other chamber is increased, so that the gas can be introduced into the first mounting tube through the first hose or the second hose. The push plate can be squeezed by the pushing effect of the gas, so that the lateral movement of the hollow seat can be automatically realized, and the automatic adjustment of the expansion head assembly can be realized. When the expansion head assembly is adjusted to the set state, the magnet is adsorbed on the circumferential inner wall of the first mounting tube to limit the expansion head assembly, and then the electromagnet is turned on, so that the excess gas can be discharged through the electromagnet in time, so as to avoid damage to the inner expansion drum caused by excessive deformation of the expansion head assembly; During this process, the piston plate evacuates gas from another chamber, and the gas can be drawn into the first installation tube through the electromagnet under the action of negative pressure to replenish the gas; The airbag and the electromagnet are connected by a hose, so that when the electromagnet is turned on, excess gas can be introduced into the airbag through the electromagnet. The airbag gradually expands after the air is taken in, so that the airbag can exert a certain pressure on the upper surface of the die-cutting raw material. The airbag can play a smoothing role in the process of conveying the die-cutting raw materials, which can effectively avoid wrinkles on the surface of the die-cutting raw materials, thereby ensuring the flatness of the die-cutting raw materials during die-cutting.

[0042] When the above-mentioned expansion shaft die-cutting machine is used, it is possible to install materials on the other expansion shaft through the hollow area while operating one of the expansion shafts for work, thereby saving the time for disassembly and installation of materials and improving the overall production efficiency. One of the expansion shaft mechanisms is in a horizontal state, and the hollow seat inside the expansion shaft mechanism moves toward the inside of the expansion shaft body, so that the connecting rod movably connected to the hollow seat pushes the installation block to slide along the limit rod, so that the expansion head extends through the second through hole, thereby supporting and fixing the material outside the outer expansion shaft body. The loss of support and fixation of the material makes it convenient for personnel to replace the material, which greatly improves the production efficiency. The convenience of personnel operation, the other expansion shaft mechanism is in a vertical state, the hollow seat inside the expansion shaft mechanism moves away from the inside of the outer expansion shaft body, and under the tension of the spring, the mounting block is driven to move toward the axial direction of the outer expansion shaft body, so that the expansion head shrinks from the second through hole, and in this process, the inner expansion shaft body and the outer expansion shaft body rotate relatively, so that the first through hole and the second through hole are staggered, thereby forming a closed space between the inner expansion shaft body and the outer expansion shaft body in the vertical state, and during the movement of the push plate, the closed space forms a negative pressure environment, which is conducive to the adsorption of materials and improves the stability of material movement.
