Description

Technical Field

[0001] This utility model relates to the field of straw cutting machine technology, specifically an adjustable straw cutting machine. Background Technology

[0002] A straw, also known as a drinking straw, is a cylindrical, hollow plastic product. Its main function is to drink beverages from cups and other containers. It can also be used to suck out the marrow from cooked animal bones. The formed plastic tube needs to be cut to the required length using cutting equipment to form a straw.

[0003] According to the description in the patent application CN 220517004 U, an adjustable straw cutting machine is disclosed, "This utility model discloses an adjustable straw cutting machine, comprising: a frame mounted on a support, with a traction mechanism on one side of the frame; a cutting mechanism located within the frame; the cutting mechanism includes a first cutting disc and a second cutting disc; the first cutting disc is connected to a first motor fixed to the outer wall of the frame via a first rotating shaft, and the first cutting disc is close to a limiting tube; the second cutting disc is connected to a second motor fixed to a support plate via a second rotating shaft, and the support plate is threadedly connected to a threaded rod; a pair of mounting grooves evenly distributed around the circumference of the cutting disc are formed on the cutting disc; an angle adjustment mechanism is installed in the mounting groove, and a cutting blade is detachably mounted at the end of the angle adjustment mechanism away from the center of the cutting disc. This utility model provides an adjustable straw cutting machine with good cutting effect, and the distance between the two cutting discs can be adjusted to adjust the cutting length of the straw, enhancing its practicality."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model uses a limiting tube to limit the plastic tube, making cutting more convenient. Then, the cutting blade cuts the plastic tube. However, the diameters of the straws are different. Thinner plastic tubes placed inside the larger limiting tube will be suspended, causing deviation during cutting and resulting in a low straw pass rate. Furthermore, when cutting plastic tubes of different diameters, it is necessary to frequently change the limiting tubes with different inner diameters, which is cumbersome. Therefore, it is necessary to improve the straw cutting machine to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable straw cutter to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable straw cutting machine, comprising a platform, a cutting box on the top of the platform, a protective door on the front of the cutting box, a viewing window inside the protective door, a motor A fixedly installed on the left side of the cutting box, a threaded rod A fixedly installed at the output end of the motor A, a movable plate installed on the external thread of the threaded rod A, an adjustment mechanism inside the cutting box, a cutting mechanism inside the cutting box, and two limiting posts fixedly installed inside the cutting box.

[0008] Preferably, the adjustment mechanism includes two rotating shafts, which are rotatably installed inside the cutting box and the moving plate, respectively. A handle is fixedly installed on the outer side of each of the two rotating shafts. A turntable is fixedly installed on the side of each rotating shaft away from the handle. A limit support hole is formed inside the turntable. Through holes are formed inside both the cutting box and the moving plate. A fixing frame is fixedly installed on the side of the handle away from the rotating shaft. A spring is fixedly installed on the inner side of the fixing frame. A circular plate is fixedly installed at the end of the spring away from the fixing frame. The moving plate is slidably installed outside the two limit posts. A positioning post is fixedly installed inside the circular plate and inserted into the positioning hole, so that the plastic tube is placed inside the two appropriately sized limit support holes, providing certain support for the plastic tube.

[0009] Preferably, the positioning pin is slidably installed inside the fixed frame and the handle, and six positioning holes are opened inside the cutting box and the moving plate, with the positioning pin inserted into the positioning hole. The position of the limiting support hole corresponds to the position of the positioning hole, so that positioning can be performed after adjustment.

[0010] Preferably, the limiting support hole and the through hole are positioned to correspond, so that the center of the limiting support hole and the through hole of different diameter sizes coincide, thereby allowing the limiting support hole to be switched according to the required diameter of the plastic tube to be cut.

[0011] Preferably, the cutting mechanism includes two motors B, which are respectively fixedly installed on the right side of the cutting box and the left side of the moving plate. A cutter disc is fixedly installed at the output end of each motor B. Four cutting blades are arranged inside the cutter disc. A protrusion A is provided on the side of each cutting blade away from the motor B. A rotating rod is rotatably installed inside the protrusion A. A threaded rod B is threaded inside the cutter disc. A rectangular block is rotatably installed outside the threaded rod B. Four protrusions B are fixedly installed outside the rectangular block, so that the movement of the protrusions B drives the rotating rod to rotate.

[0012] Preferably, the end of the rotating rod away from protrusion A is rotatably mounted inside protrusion B, so that protrusion A drives the cutting blade to rotate inside the blade disc.

[0013] Preferably, a limiting disc is fixedly installed at one end of the threaded rod B near the motor B, and the limiting disc is movably installed inside the cutter disc to prevent the threaded rod B from dislodging from the inside of the cutter disc due to rotational errors.

[0014] Compared with the prior art, this utility model provides an adjustable straw cutter, which has the following beneficial effects:

[0015] 1. This adjustable straw cutter uses a turntable to align the center of the limiting support holes of different diameters with the center of the through hole, allowing the limiting support holes to be switched according to the required diameter of the plastic tube to be cut. A spring drives the positioning pin to insert into the positioning hole, so that the plastic tube is placed inside the two appropriately sized limiting support holes, providing a certain support for the plastic tube. This results in a better cutting effect when the cutter cuts the plastic tube, and the switching between the limiting support holes is faster, eliminating the need for frequent replacements.

[0016] 2. Based on this, the present invention uses the threaded rod B to drive the rectangular block to move, which causes the rotating rod to rotate, and the protrusion A to drive the cutting blade to rotate inside the cutter disc. This allows the angle between the cutting blades to be selected, with one set of cutting blades in a vertical position and the other set at an angle, so that plastic tubes can be cut at any angle, thus expanding the range of applications.

[0017] 3. Based on this, the present invention allows the movable plate to slide outside the cutting box (2) and the two limiting posts through the threaded rod A, thereby adjusting the distance between the two cutter discs and thus adjusting the cutting length of the suction tube, which enhances its practicality.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Example 1:

[0029] Please see Figure 1-4 This utility model provides a technical solution: an adjustable straw cutting machine, including a platform 1, a cutting box 2 on the top of the platform 1, a protective door 3 on the front of the cutting box 2, a viewing window 4 inside the protective door 3, a motor A5 fixedly installed on the left side of the cutting box 2, a threaded rod A6 fixedly installed at the output end of the motor A5, a movable plate 7 installed on the external thread of the threaded rod A6, an adjustment mechanism 8 inside the cutting box 2, a cutting mechanism 9 inside the cutting box 2, and two limiting posts 10 fixedly installed inside the cutting box 2.

[0030] Furthermore, the adjustment mechanism 8 includes two rotating shafts 81, which are rotatably installed inside the cutting box 2 and the moving plate 7, respectively. A handle 82 is fixedly installed on the outer side of each of the two rotating shafts 81, and a turntable 83 is fixedly installed on the side of each of the two rotating shafts 81 away from the handle 82. A limit support hole 84 is opened inside the turntable 83. A through hole 85 is opened inside the cutting box 2 and the moving plate 7. A fixing frame 86 is fixedly installed on the side of the handle 82 away from the rotating shaft 81. A spring 87 is fixedly installed on the inner side of the fixing frame 86. A circular piece 88 is fixedly installed on the end of the spring 87 away from the fixing frame 86. The moving plate 7 is slidably installed outside the two limit posts 10. A positioning post 89 is fixedly installed inside the circular piece 88. The positioning post 89 is inserted into the positioning hole, so that the plastic tube is placed inside the two appropriately sized limit support holes 84, providing a certain support for the plastic tube.

[0031] Furthermore, the positioning pin 89 is slidably installed inside the fixed frame 86 and the handle 82. The cutting box 2 and the moving plate 7 are both provided with six positioning holes, and the positioning pin 89 is inserted into the positioning hole. The position of the limiting support hole 84 corresponds to the position of the positioning hole, so that positioning can be performed after adjustment.

[0032] Furthermore, the limiting support hole 84 and the through hole 85 are positioned to correspond, so that the center of the limiting support hole 84 and the through hole 85 of different diameter sizes coincides, thereby allowing the limiting support hole 84 to be switched according to the required diameter of the plastic tube to be cut.

[0033] Example 2:

[0034] Please see Figure 5-6 Furthermore, in conjunction with Embodiment 1, the cutting mechanism 9 includes two motors B91, which are respectively fixedly installed on the right side of the cutting box 2 and the left side of the moving plate 7. A cutter disc 92 is fixedly installed at the output end of the motors B91. Four cutting blades 93 are arranged inside the cutter disc 92. A protrusion A94 is arranged on the side of the cutting blade 93 away from the motors B91. A rotating rod 95 is rotatably installed inside the protrusion A94. A threaded rod B96 is threaded inside the cutter disc 92. A rectangular block 97 is rotatably installed outside the threaded rod B96. Four protrusions B98 are fixedly installed outside the rectangular block 97, so that the movement of the protrusions B98 drives the rotating rod 95 to rotate.

[0035] Furthermore, the end of the rotating rod 95 away from the protrusion A94 is rotatably mounted inside the protrusion B98, so that the protrusion A94 drives the cutting blade 93 to rotate inside the cutter head 92.

[0036] Furthermore, a limiting disc is fixedly installed at one end of the threaded rod B96 near the motor B91, and the limiting disc is movably installed inside the cutter head 92 to prevent the threaded rod B96 from disengaging from the cutter head 92 due to rotational errors.

[0037] In actual operation, when this device is used, pulling the positioning pin 89 away from the fixed frame 86 causes the positioning pin 89 to disengage from the positioning hole inside the cutting box 2 and the moving plate 7. At this time, the disc 88 approaches the fixed frame 86, causing the spring 87 to be compressed. The spring 87 is initially in a stretched state. Then, turning the handle 82 drives the rotating shaft 81 to rotate, thereby causing the turntable 83 to rotate. This causes the center of the limiting support hole 84 with different diameter sizes to coincide with the center of the through hole 85, allowing the limiting support hole 84 to be switched according to the required diameter of the plastic tube to be cut. Then, releasing the spring 87 causes the spring 87 to rebound, causing the disc 88 to return to its original position. This causes the disc 88 to drive the positioning pin 89 to be inserted into another positioning hole, so that the plastic tube is placed inside the two appropriately sized limiting support holes 84, providing a certain support for the plastic tube, and allowing the cutting blade 93 to... The cutting effect is good when cutting plastic tubes, and the switching between the limiting support holes 84 is faster, eliminating the need for frequent replacements and making it more convenient. Then, the threaded rod B96 is rotated and threaded inside the cutter head 92, driving the rectangular block 97 to move, causing the protrusion B98 to move and drive the rotating rod 95 to rotate, causing the protrusion A94 to drive the cutting blade 93 to rotate inside the cutter head 92. The angle between the cutting blades 93 can be selected, with one set of cutting blades 93 in a vertical state and the other set at an angle, allowing for arbitrary angled cutting of plastic tubes, thus expanding the range of applications. Starting the motor A5 drives the threaded rod A6 to rotate, causing the moving plate 7 to slide outside the cutting box 2 and the two limiting posts 10, which can adjust the distance between the two cutter heads 92, thereby adjusting the cutting length of the straw and enhancing practicality.

[0038] It should be noted that both platform 1 and cutting box 2 have rectangular slots for feeding, and the limiting post 10 is set in the rectangular slot for feeding of cutting box 2.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
