AI Technical Summary
Existing straw production equipment is limited by the spacing of the limiting holes when adjusting the length, and cannot be adjusted freely. Furthermore, the lack of an effective limiting structure during cutting leads to excessive deformation and cutting failure.
The positioning structure uses a combination of a cylinder telescopic rod and a limiting plate. The position of the limiting plate is adjusted by the cylinder telescopic rod, and the suction tube is precisely positioned by a hydraulic pump and a blocking plate. The cutting structure uses a rotating shaft and a cutting frame, equipped with a limiting ring and a motor drive, to ensure that the suction tube remains fixed during the cutting process.
It enables free adjustment of straw length and effective support during the cutting process, improving cutting efficiency and success rate, and avoiding cutting failure caused by excessive straw deformation.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of straw production technology, specifically a cutting device for producing drinking straws. Background Technology
[0002] Straws are hollow plastic products, usually made by heating the raw materials to a molten state, cooling them, and then cutting them. They are generally used in the catering industry.
[0003] In the prior art, for example, a cutting device for producing drinking straws disclosed in CN218837928U, the device uses a periodic hammer to strike a cutting blade holder, thereby enabling the cutting blade to cut the straw, and adjusts the length of the cut straw through a support or other structure.
[0004] In actual use, the above-mentioned device uses the method of adjusting the position of the bracket when adjusting the length of the straw. This method will cause the adjusted straw length to be limited by the spacing of the limiting holes, so it is impossible to adjust the straw length to any length. In addition, when cutting the straw, the cutting blade will squeeze the straw, causing the straw to deform before being cut. However, the above-mentioned device does not have a limiting structure at this point, which can easily lead to excessive deformation of the straw during cutting, resulting in the straw and the cutting blade moving together and causing the cutting to fail. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] It solves the problem that the distance cannot be freely adjusted due to the limitation of the spacing of the limiting holes when adjusting the straw length; it also solves the problem that the lack of an effective limiting structure when cutting straws easily leads to cutting failure.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Example 1
[0028] Reference Figure 1-3 This is the first embodiment of the present invention, providing a cutting device for producing drinking straws, including a feeding platform 1, which is a cylindrical frustum with a supporting base parallel to the ground on its bottom side, and the base is fixed to the ground. A discharging platform 11 is provided on one side of the feeding platform 1. The discharging platform 11 has the same shape as the feeding platform 1, but its thickness is much smaller than that of the feeding platform 1, and the discharging platform 11 is also fixed to the ground. Five circular holes 12 are evenly distributed on the discharging platform 11, and the feeding platform 1 also has… The same circular hole 12 is provided for the straw to pass through. A limiting pipe 13 is fixedly connected to the feeding platform 1. The cross-section of the limiting pipe 13 is larger than that of a semi-circular ring, and the inner diameter is the same as that of the circular hole 12. After the straw passes through the circular hole 12, it will be wrapped by the limiting pipe 13, which is larger than a semi-circle, so that the straw will not fall out of the limiting pipe 13. In addition, the limiting pipe 13 is also fixedly connected to the discharging platform 11. The limiting pipe 13 on the feeding platform 1 is shorter, while the limiting pipe 13 on the discharging platform 11 is longer.
[0029] It also includes a positioning structure on the discharge platform 11;
[0030] The positioning structure includes a mounting plate 21 fixed to the limiting pipe 13. The mounting plate 21 consists of two parts: an outer ring-shaped plate fixed to the limiting pipe 13 and a middle circular plate with a square slot. A cylinder telescopic rod 22 is fixed to the mounting plate 21 and installed in the square slot in the middle part of the mounting plate 21. The cylinder telescopic rod 22 is also fixedly connected to the discharge platform 11 through the limiting rod. A limiting plate 23 is fixed to one side of the cylinder telescopic rod 22. The limiting plate 23 can be accessed by the cylinder telescopic rod 22. The position of the limiting plate 23 on the limiting pipe 13 is controlled by the extension and retraction of 2. The liquid storage tank 24 is set in the limiting plate 23. The liquid storage tank 24 stores oil. The delivery pipe 25 is fixed on the liquid storage tank 24. The liquid storage tank 24 and the hydraulic pump 26 are connected through the delivery pipe 25. The hydraulic pump 26 is fixed on the delivery pipe 25. The hydraulic pump 26 can be controlled by an external control system. When the suction pipe has not been cut, the hydraulic pump 26 is started. When the suction pipe is cut, the hydraulic pump 26 is turned off. The baffle plate 27 is set on one side of the hydraulic pump 26.
[0031] A support plate 28 is provided on one side of the baffle plate 27. The baffle plate 27 is an arc-shaped plate and is rotatably connected to the support plate 28. It is also connected to the support plate 28 via a hydraulic telescopic rod. The hydraulic telescopic rod is connected to the hydraulic pump 26 via a delivery pipe 25. When the hydraulic pump 26 applies oil pressure to the baffle plate 27 in the support plate 28, it forces the baffle plate 27 to open, thereby blocking the suction pipe that wants to pass through the through hole 29. When the hydraulic pump 26 is turned off, the baffle plate 27 will retract into the support plate 28, allowing the suction pipe to pass through the through hole 29. The support plate 28 is connected to the hydraulic pump 26 via the delivery pipe 25.
[0032] The limiting plate 23 has a through hole 29, the diameter of which is larger than that of the limiting pipe 13, so that the limiting plate 23 can be slidably connected to the limiting pipe 13.
[0033] The lower side of the limiting plate 23 is connected to a pulley 210. The pulley 210 is used to reduce the friction when the limiting plate 23 is displaced and can support the positional relationship between the limiting plate 23 and the limiting pipe 13. The feeding table 1 is equipped with a cutting structure.
[0034] During use, the length of the suction tube needs to be positioned before cutting. When the suction tube enters through the round hole 12 of the feeding platform 1 and enters the limiting pipe 13, the cylinder extension rod 22 can be activated to adjust the position of the limiting plate 23. The cylinder extension rod 22 is extended to a suitable length, i.e., the required suction tube length, and then the extension and retraction of the cylinder extension rod 22 is stopped. When the cylinder extension rod 22 is activated, the hydraulic pump 26 is always in the activated state. When the hydraulic pump 26 is activated, it will transport the oil in the storage tank 24 to the support plate 28 through the delivery pipe 25. The oil has a certain pressure, which can drive the hydraulic extension rod connecting the blocking plate 27 and the support plate 28, so that the blocking plate 27 can rotate around the axis and open in the through hole 29 and play a blocking role, so that the suction tube cannot continue to pass through, thereby completing the limiting function of the suction tube.
[0035] When the cut straw needs to continue passing through, the hydraulic pump 26 is turned off and the baffle plate 27 is retracted into the carrier plate 28. At this time, due to the subsequent delivery of the straw, the cut straw will be pushed out of the limiting pipe 13 and discharged through the round hole 12 on the discharge platform 11. The end of the discharge platform 11 can also be connected to a straw transport device for transporting the cut straw. When the uncut straw is about to contact the baffle plate 27, the hydraulic pump 26 is started to reopen the baffle plate 27 for limiting.
[0036] Example 2
[0037] Reference Figure 1-5This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the cutting structure includes a rotating shaft 31 rotatably connected to the feeding table 1. A motor is provided on one side of the rotating shaft 31. The motor is located inside the feeding table 1 and is used to drive the rotating shaft 31 to rotate. A cutting frame 32 is fixed on the rotating shaft 31. The cutting frame 32 and the rotating shaft 31 are fixedly connected. A cutting blade 33 is provided on the cutting frame 32. The cutting blade 33 rotates in the gap between the limiting pipe 13 on the feeding table 1 and the limiting pipe 13 on the discharge table 11.
[0038] A limiting ring 34 is fixedly connected to the outer side of the cutting frame 32. The limiting ring 34 is rotatably connected to the feeding table 1, which can prevent the cutting blade 33 from being accidentally deformed or deviated during the cutting process. A motor is provided on one side of the rotating shaft 31.
[0039] During use, when the straw is fed from the round hole 12 on the feeding platform 1 into the limiting pipe 13, the straw is simultaneously located in the limiting pipe 13 of the feeding platform 1 (hereinafter referred to as the short limiting pipe) and the limiting pipe 13 of the discharging platform 11 (hereinafter referred to as the long limiting pipe). The short limiting pipe and the long limiting pipe always maintain a certain distance, which is the distance that the cutting blade 33 can pass through. At this time, the rotating shaft 31 driven by the motor and the cutting frame 32 rotate, and the cutting blade 33 is set on the cutting frame 32. During the rotation, the cutting blade 33 passes through the area between the short limiting pipe and the long limiting pipe. Therefore, the cutting blade 33 can cut the straw in the limiting pipe 13 during the rotation. The straw is limited by the limiting pipe 13. Therefore, the straw is always supported and limited during the cutting process, so it can be cut well. Five straws can be cut at the same time in a single cutting process, which improves efficiency and increases the success rate of cutting.
[0040] The remaining structure is the same as that in Example 1.
[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
