DETAILED DESCRIPTION

[0020] See also Figure 1-4 The utility model provides a plastic straw processing and forming machine, including a mounting seat 1, a rotating disk 2 is arranged at one end of the mounting seat 1, a rotating shaft 3 is rotatably connected to the middle position of the mounting seat 1, one end of the rotating shaft 3 is fixed to the middle position of the surface of one end of the rotating disk 2, a connecting block 5 is fixed to the bottom of the outer circumference of the rotating disk 2, a resistance hole 6 is opened through the surface of the connecting block 5, a slide bar 7 is arranged on one side of the connecting block 5, a support hole 8 is opened through the surface of the slide bar 7, a gear 14 is fixedly sleeved on one end of the outer circumference of the rotating shaft 3, a rack 15 is meshed at the bottom of the gear 14, and the surface of one end of the mounting seat 1 is fixed at the position at the bottom of the connecting bar 20 There are two fixed blocks 16, and a positioning rod 17 is fixed at the middle position of the two fixed blocks 16. A sliding sleeve 18 is slidably sleeved on the outer circumference of the positioning rod 17. The top of the sliding sleeve 18 is fixed to the surface of the bottom of the connecting strip 20. Springs 19 are sleeved on the outer circumference of the positioning rod 17 at positions on both sides of the sliding sleeve 18. By extending one side of the straw to the inside of the abutment hole 6 and the other side to the inside of the support hole 8, the rotating shaft 3 is rotated to make the rotating disk 2 drive the connecting block 5 to rotate, so that the straw can be bent under the drive of the connecting block 5, thereby ensuring that the bending position of the straw is consistent to improve the uniformity and aesthetics of the straw after bending.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that two mounting blocks 9 are fixed on the surface of one end of the mounting seat 1 near the slide bar 7, a positioning shaft 11 is fixed at the middle position of the two mounting blocks 9, and a slider 12 is slidably sleeved on the outer circumference of the positioning shaft 11, and one end of the slider 12 is fixed to the surface of the slide bar 7. Since the slider 12 can only slide along the outer circumference of the positioning shaft 11, the position of the slide bar 7 can be adjusted, thereby facilitating extending one side of the straw to the inside of the support hole 8 or extending it out from the inside of the support hole 8.

[0022] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that two magnetic rods 10 are fixed on one side of the mounting block 9 close to each other, and two magnetic holes 13 are provided on the surface of the slider 12, wherein one side of the two magnetic rods 10 extends to the inside of the magnetic hole 13 at the adjacent position and fits with the inner circumferential surface of the magnetic hole 13, and when the slider 12 slides along the outer circumferential surface of the positioning shaft 11, one side of the magnetic rod 10 can extend to the inside of the magnetic hole 13 at the adjacent position, so that the slider 12 can be limited by the magnetic attraction between the magnetic rod 10 and the magnetic hole 13.

[0023] Further as Figure 4 As shown, it is worth explaining in detail that a sleeve handle 4 is fixedly provided at a position where the outer circumference of the rotating shaft 3 is located at one end of the gear 14, the side of the springs 19 that are close to each other is fixed to the surface of the sliding sleeve 18, and the side of the springs 19 that are away from each other is fixed to the surface of the adjacent fixed block 16, a connecting strip 20 is fixedly provided at a position where the outer circumference of the rotating shaft 3 is located at one end of the sleeve handle 4, and an L-shaped positioning strip 21 is fixedly provided at a position where the surface of one end of the mounting seat 1 is located at the top of the gear 14, so that the user can rotate the rotating shaft 3 by rotating the sleeve handle 4, and due to the connection setting of the spring 19, when the rotating shaft 3 rotates to drive the sliding sleeve 18 to slide, it can directly contact the adjacent spring 19 to deform it, thereby facilitating the resetting of the angle of the rotating shaft 3 after rotation, and when the rotating shaft 3 rotates, the rotation angle of the rotating shaft 3 can be limited by the interference between the connecting strip 20 and the positioning strip 21.

[0024] The present solution has the following working process: in actual use, when the user needs to bend the straw, the corrugated section at one end of the straw is extended to the inside of the abutting hole 6, and then the sliding bar 7 is used to slide the straw along the outer circumference of the positioning shaft 11 so that the other end of the straw is extended to the inside of the supporting hole 8, and then the sleeve 4 is rotated to rotate the rotating shaft 3, so that the rotating shaft 3 can drive the gear 14 to rotate, so that the connecting bar 20 can drive the sliding sleeve 18 to slide under the meshing action between the gear 14 and the connecting bar 20, so that the sliding sleeve 18 can slide along the outer circumference of the positioning rod 17 to abut against the adjacent position spring 19 to deform it, so that the rotating shaft 3 rotates and drives the connecting block 5 to rotate, so that the corrugated section of the straw that abuts against the abutting hole 6 is bent, so that the corrugated section of the straw can be bent to a certain angle. The rotation of the shaft 3 allows the connecting strip 20 to perform a circular motion, so that the rotating shaft 3 can be bent ninety degrees at a time under the interference between the connecting strip 20 and the positioning strip 21, thereby ensuring that the angle of the straw bent by the device is constant each time, which not only ensures that the bending position of the straw is consistent, but also improves the uniformity and aesthetics of the straw after bending. After the straw is bent, the slider 12 can move horizontally under the limiting action of the positioning shaft 11 by sliding the slider 7, so that the slider 7 moves horizontally to allow one side of the straw to extend out from the inside of the support hole 8, thereby moving the straw vertically downward so that the corrugated section of the straw is disengaged from the inside of the interference hole 6, and then loosening the handle 4 so that the sliding sleeve 18 can be reset under the action of the rebound force of the spring 19, so that the rotating shaft 3 drives the connecting block 5 to return to the initial state to facilitate the bending operation of the next straw.

[0025] According to the above working process, it can be known that: by extending one side of the straw to the inside of the abutment hole 6 and the other side of the straw to the inside of the support hole 8, the rotating shaft 3 is rotated to make the rotating disk 2 drive the connecting block 5 to rotate, so that the straw can be bent under the drive of the connecting block 5, thereby ensuring that the bending position of the straw is consistent, improving the uniformity and aesthetics of the straw after bending, thereby improving the practicality of the device, and the slider 12 can slide the slide bar 7, so that one side of the straw can be extended out of the slide bar 7 after bending, so that the bent straw can be directly taken out to avoid affecting the bending state of the straw during disassembly, thereby further improving the practicality of the device.

[0026] Further as Figure 1 and Figure 2As shown, it is worth explaining in detail that the diameter at the middle position of the surface of the rotating disk 2 is smaller than the two ends of the outer circumference of the rotating disk 2, and the interference hole 6 and the support hole 8 are at the same horizontal height. The shape of the rotating disk 2 is set to facilitate the placement of the straw in the middle position of the surface of the rotating disk 2 when it is bent to prevent it from tilting during the bending operation under the action of the interference. The height setting of the interference hole 6 and the support hole 8 ensures that the unbent part remains horizontal.

[0027] In summary: by extending one side of the straw to the inside of the interference hole 6 and the other side of the straw to the inside of the support hole 8, the rotating shaft 3 is rotated to make the rotating disk 2 drive the connecting block 5 to rotate, so that the straw can be bent under the drive of the connecting block 5, thereby ensuring that the bending position of the straw is consistent, improving the uniformity and aesthetics of the straw after bending, thereby improving the practicality of the device, and the slider 12 can slide the slide bar 7, so that it is convenient to extend one side of the straw to the outside of the slide bar 7 after bending, so that it is convenient to directly take out the bent straw to avoid affecting the bending state of the straw during disassembly, thereby further improving the practicality of the device, and the shape setting of the rotating disk 2 makes it convenient to place the straw in the middle position of the surface of the rotating disk 2 when bending to avoid it from being skewed during the bending operation under the action of the interference, and the height setting of the interference hole 6 and the support hole 8 ensures that the unbent part remains horizontal.
