[0005] The above patent uses a support frame to open the packaging bag and uses a slide and a baffle to limit and guide the hat, thereby ensuring that the staff can stably bag the hat and improving the convenience of using the device.

[0006] However, the above patent is not applicable to the packaging of disposable protective caps. Currently, disposable protective caps are still packaged manually, which has low packaging efficiency. Summary of the invention

[0007] The invention provides an automatic folding machine for disposable protective caps, aiming to solve the problem of low packaging efficiency in the related art.

[0008] The automatic folding machine for disposable protective caps of the present invention comprises: a frame, a rotating disk and a packaging assembly; The frame is provided with a feeding conveyor belt and a discharging conveyor belt; The rotating disk is rotatably engaged with the frame, and the packaging assembly includes a frustum, a rotating mechanism, a limit plate group, a fixed seat, a rotating plate group and a driving rod. The frustum is arranged on the side wall of the rotating disk, and the rotating mechanism is rotatably engaged with the frustum. The rotating mechanism is used to roll the disposable protective cap into a cylindrical shape. The limit plate group has a plurality of limit plates, and the plurality of limit plates are all arranged on the side wall of the frustum. The fixed seat is arranged on the end surface of the frustum. The rotating plate group has a plurality of rotating plates, and one end of each rotating plate is rotatably engaged with the fixed seat. The driving rod is slidably engaged with the frustum, and is used to drive the rotating plate to rotate. A rubber band is sleeved on the side wall of the frustum, and the rotation of the rotating plate can tie the rubber band to the disposable protective cap.

[0009] Beneficial effect: The disposable protective cap is placed on the feed conveyor belt, and is sent to the packaging assembly through the feed conveyor belt. The disposable protective cap is rolled into a cylindrical shape through the rotating mechanism, and the rotating plate group is driven to rotate by the driving rod to hook the rubber band from the side wall of the cone. The rubber band moves along the limiting plate and is finally bundled on the rolled disposable protective cap, thereby realizing the automatic packaging of the disposable protective cap and being discharged from the disposable protective cap automatic folding machine through the discharging conveyor belt.

[0010] Preferably, the rotating mechanism includes a mounting seat, a first lever and a second lever, the mounting seat is rotationally coordinated with the frustum, a first driving member is provided in the frustum, the first driving member is used to drive the mounting seat to rotate, and the first lever and the second lever are spaced apart and distributed on the mounting seat.

[0011] Preferably, the rotating plate group includes a first rotating plate and a second rotating plate, the inner end of the first rotating plate is rotatably matched with a connecting block, the connecting block is provided with a limiting protrusion, and the frustum is provided with a matching groove, the inner end of the first rotating plate can extend into the matching groove, so that the limiting protrusion can hook the rubber band sleeved on the frustum.

[0012] The effect is that the limiting protrusion can stop against the rubber band, thereby preventing the rubber band from falling off the first limiting plate due to its own elastic force when the first rotating plate hooks up the rubber band.

[0013] Preferably, the connection block is also rotatably matched with a limiting block, a limiting groove is formed between the limiting block and the limiting protrusion, and the cross-sectional dimension of the limiting groove is the same as the cross-sectional dimension of the rubber band.

[0014] The effect is that the cross-sectional size of the limiting groove is the same as the cross-sectional size of the rubber band, so that only one rubber band can be present in the limiting groove, thereby preventing multiple rubber bands from being bundled on a disposable protective cap and reducing the waste of rubber bands.

[0015] Preferably, the driving rod is respectively provided with a first push rod and a second push rod, the first push rod is abutted against the first rotating plate, the second push rod is abutted against the second rotating plate, the second rotating plate has a first section and a second section, the first section is close to the cone, and its thickness is smaller than that of the second section.

[0017] The effect is that when the second push rod moves along the first section of the second rotating plate, the angle between the first limit plate and the cone is greater than the angle between the second limit plate and the cone. Since the elastic force of the first torsion spring is less than the elastic force of the second torsion spring, the rubber band will first push the second limit plate to rotate. When the rubber band passes over the second limit plate, it will push the third limit plate to rotate. In this process, different limit plates are kept in place to continuously limit the rubber band mounted on the cone, preventing the rubber band mounted on the side wall of the cone from falling off the cone.

[0018] Preferably, the top end of the first limiting plate is rotatably matched with a toggle plate.

[0019] The effect is that after the first rotating plate hooks up the rubber band, it will pass through the rotating path of the toggle plate. During the rotation process, the toggle plate will stop with the first rotating plate and pull down the excess rubber band on the first rotating plate, preventing the first rotating plate from hooking up multiple rubber bands at a time.

[0020] Preferably, a plurality of the packaging assemblies are distributed on the side wall of the rotating disk at intervals along the circumference of the rotating disk.

[0021] Preferably, the feed conveyor belt and the discharge conveyor belt are spaced apart up and down, the packaging assembly is located between the feed conveyor belt and the discharge conveyor belt, a third push rod is slidably fitted on the frame, a limiting claw is provided at the end of the third push rod, and the third push rod can push the disposable protective cap on the packaging assembly onto the discharge conveyor belt.

A first driving member 524 is provided in the cone 51. The first driving member 524 is a motor, and its output end is fixedly connected to the mounting seat 521. The first driving member 524 is used to drive the mounting seat 521 to rotate. The limiting plate group includes a first limiting plate 531, a second limiting plate 532 and a third limiting plate 533. The first limiting plate 531 is fixedly connected to the side wall of the cone 51, the second limiting plate 532 is rotatably connected to the side wall of the cone 51 through a first torsion spring, and the third limiting plate 533 is rotatably connected to the side wall of the cone 51 through a second torsion spring. The first limiting plate 531, the second limiting plate 532 and the third limiting plate 533 are distributed at intervals along the axial direction of the cone 51, and the elastic force of the second torsion spring is smaller than the elastic force of the third torsion spring. The fixed seat 54 is fixedly connected to the end surface of the small diameter end of the frustum 51, and the rotating plate group includes a first rotating plate 551 and a second rotating plate 552. The first rotating plate 551 and the second rotating plate 552 are symmetrically distributed on the upper and lower sides of the fixed seat 54. The outer ends of the first rotating plate 551 and the second rotating plate 552 are respectively rotatably connected to the fixed seat 54 through a fifth torsion spring. The inner end of the first rotating plate 551 is provided with a connecting block 6, and the connecting block 6 is rotatably connected to the first rotating plate 551 through a third torsion spring. A limiting protrusion 61 is provided on the connecting block 6, and a limiting block 7 is also provided on the connecting block 6.

The connecting block 6 can pass through the avoidance groove and extend into the matching groove. There is a gap between the inner end of the second rotating plate 552 and the small diameter end of the cone 51 .

[0034] like Figure 3As shown, the driving rod 56 is slidably fitted inside the cone 51 and is rotatably fitted with the mounting seat 521. A hydraulic cylinder is provided inside the cone 51, and the output end of the hydraulic cylinder is fixedly connected to the driving rod 56. The hydraulic cylinder is used to drive the driving rod 56 to move along its axial direction, and the driving rod 56 can extend out of the cone 51. The top and bottom ends of the driving rod 56 are respectively provided with a first push rod 561 and a second push rod 562. The first push rod 561 and the second push rod 562 are both T-shaped structures. The first push rod 561 can stop with the first rotating plate 551, and the second push rod 562 can stop with the second rotating plate 552. When the driving rod 56 gradually extends outward from the cone 51, the first push rod 561 and the second push rod 562 respectively push the first rotating plate 551 and the second rotating plate 552 to rotate, so that the distance between the inner ends of the first rotating plate 551 and the second rotating plate 552 and the axis of the cone 51 gradually increases.

[0035] like Figure 3 and Figure 6 As shown, the second rotating plate 552 has a first section 5521 and a second section 5522. The first section 5521 is close to the inner end of the second rotating plate 552, and its thickness is less than the thickness of the second section 5522. When the driving rod 56 pushes the first rotating plate 551 and the second rotating plate 552 to rotate through the first push rod 561 and the second push rod 562, the second push rod 562 first stops with the first section 5521, so that the angle between the second rotating plate 552 and the axis of the cone 51 is smaller than the angle between the first rotating plate 551 and the axis of the cone 51. When the second push rod 562 stops with the second section 5522, the angle between the second rotating plate 552 and the axis of the cone 51 is equal to the angle between the first rotating plate 551 and the axis of the cone 51.

[0036] like Figure 3 and Figure 7 As shown, a toggle plate 8 is also provided at the top of the first limit plate 531. The toggle plate 8 is rotatably connected to the first limit plate 531 through a rotating shaft 9. The rotating bottom end can extend into the cone 51. A driving rack is provided on the driving rod 56. A driving gear is provided on the rotating shaft 9. The driving gear can engage with the driving rack, so that the driving rod 56 can also drive the toggle plate 8 to rotate during the movement.

[0037] like Figure 1 As shown, a third push rod 10 is also provided on the frame body 1. The third push rod 10 is slidably matched with the frame body 1, and a limiting claw 11 is provided at the end thereof. A hydraulic cylinder is provided in the frame body 1 for driving the third push rod 10 to move along its axial direction. The third push rod 10 can push the disposable protective cap packaged on the packaging assembly 5 onto the discharge conveyor belt 3.

[0038] According to the automatic folding machine for disposable protective caps of the embodiment of the present invention, the disposable protective caps are placed on the right end of the feeding conveyor belt 2, and the feeding conveyor belt 2 transfers the disposable protective caps to the left end thereof, and the disposable protective caps are extended between the first lever 522 and the second lever 523, and the mounting seat 521 rotates to rotate the first lever 522 and the second lever 523, thereby rolling the disposable protective caps into a cylindrical shape, and then the driving rod 56 extends outward, and the first push rod 561 and the second push rod 562 respectively push the first rotating plate 551 and the second rotating plate 552 to rotate in opposite directions, and then the disposable protective caps are rolled into a cylindrical shape. During the rotation of the first rotating plate 551, the connecting block 6 can stop against the rubber band sleeved on the side wall of the cone 51 and hook up the rubber band. At this time, there will be a rubber band in the limiting groove, and the driving rack on the driving rod 56 will mesh with the driving gear on the rotating shaft 9. The movement of the driving rod 56 will drive the toggle plate 8 to rotate. When the first rotating plate 551 rotates until the connecting block 6 is flush with the top of the first limiting plate 531, the toggle plate 8 will push away the excess rubber band on the connecting block 6, and the pushed away rubber band will be re-sleeved on the cone 51, and the rubber band in the limiting groove will continue to be stretched. The rubber band can apply pressure to the limiting block 7, so that the limiting block 7 can overcome the elastic force of the fourth torsion spring and rotate, and the limiting block 7 is received in the connecting block 6, so that the rubber band moves along the connecting block 6 and the first rotating plate 551 under the action of its own elastic force. When the rubber band is gradually stretched, it applies pressure to the second limiting plate 532 and the third limiting plate 533. When the pressure is greater than the elastic force of the first torsion spring, the second limiting plate 532 rotates, so that the stretched rubber band can pass over the second limiting plate 532 and move outward, and then the second limiting plate 532 returns to its original position. When the pressure is greater than the elastic force of the second torsion spring, the second limiting plate 532 rotates, and the third limiting plate 533 and the second rotating plate 552 stop, so that the stretched rubber band can be sleeved on the second rotating plate 552 along the third limiting plate 533. As the driving rod 56 gradually extends out of the cone 51, the inner end of the first rotating plate 551 and the second The distance between the inner end of the rotating plate 552 and the axis of the cone 51 gradually increases, and the rubber band gradually moves from the inner ends of the first rotating plate 551 and the second rotating plate 552 to the outer ends of the first rotating plate 551 and the second rotating plate 552 under the action of its own elastic force, and finally detaches from the first rotating plate 551 and the second rotating plate 552, and is fastened to the rolled disposable protective cap to complete the packaging. Then the rotating disk 4 rotates, so that the packaged disposable protective cap moves to the top of the rotating disk 4, and under the push of the third push rod 10, moves to the discharge conveyor belt 3, and the discharge conveyor belt 3 can discharge the packaged third push rod 10 out of the disposable protective cap automatic folding machine.

[0039] After packaging is completed, the driving rod 56 is retracted into the cone 51, and the first rotating plate 551 and the second rotating plate 552 are reset under the action of the fifth torsion spring. When the connecting block 6 moves to the cone 51, the connecting block 6 and the rubber band sleeved on the cone 51 stop, and the rubber band enables the connecting block 6 to rotate while overcoming the elastic force of the third torsion spring. When the connecting block 6 passes over the rubber band, the connecting block 6 is reset under the elastic force of the third torsion spring.
