Description

Technical Field

[0001] This utility model relates to the field of straw processing technology, specifically to an equidistant cutting device for straw processing. Background Technology

[0002] In the straw manufacturing process, a long plastic straw blank typically needs to be cut into individual straws of the same length, with the length error between each straw controlled within a very small range. This requires equidistant cutting, which involves cutting continuous straw raw materials at equal length intervals to obtain straw products of consistent dimensions.

[0003] Chinese patent CN222135074U discloses a biodegradable straw cutting device. This device comprises a cutting assembly consisting of a motor, a rotating shaft, a turntable, a pin, a movable ring, a cutting rod, cutting scissors, and a slant plate; and a positioning assembly consisting of first and second positioning screws, a positioning block, a soft pad, a T-slot, a slider, and a support block. The motor rotates the rotating shaft and turntable, causing the pin to move and the movable ring to move up and down. When the movable ring moves downwards, it drives the cutting rod and cutting scissors to cut the straw placed in the cutting hole. The cut straw falls into a collection box. Simultaneously, rotating the first and second positioning screws moves the positioning block to clamp the straw, and the soft pad increases friction and reduces damage, preventing the straw from tilting. However, after long-term use, the cutting scissors may wear out, there is a lack of a convenient replacement mechanism, and it cannot perform synchronous and equidistant cutting of the straw.

[0004] In view of the above-mentioned related technologies, an equidistant cutting device for straw processing is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

A hydraulic cylinder 2 is fixedly installed at the top of the frame 1, and a blade base 3 is fixedly connected to its output end. Two guide rods 31 are symmetrically fixedly installed on the blade base 3, slidingly connected within the guide grooves 10 of the frame 1 to ensure smooth movement of the blade base 3 and improve cutting accuracy. An equidistant cutting assembly 6 is fixedly installed on the blade base 3.

[0025] The equidistant cutting assembly 6 includes a connecting plate 61. A cylinder 62 is fixedly installed on the top of the connecting plate 61. A linkage push rod 63 is fixedly connected to the output end of the cylinder 62. A sliding groove 630 is opened at the bottom end of the linkage push rod 63. Multiple blade arms 64 are slidably connected to the sliding groove 630. A connector 641 is sleeved on one end of the blade arm 64. A blade head 65 is detachably connected to the other end of the blade arm 64. An accordion groove 610 for adjusting the spacing of the blade arms 64 is opened on the connecting plate 61. The connector 641 is slidably connected in the accordion groove 610. By pushing the linkage push rod 63 with the cylinder 62, and with the cooperation of the sliding groove 630, the connector 641 and the accordion groove 610, the spacing of the multiple blade arms 64 can be adjusted, and the position of the blade head 65 can be flexibly adjusted to meet different equidistant cutting requirements. The connecting plate 61 has scale lines 611 on both sides of the panel for reading the spacing value. The two ends of the linkage push rod 63 are fixedly installed with sensors 631 for reading the scale line 611 value, which can accurately read the spacing of the cutter arm 64, improve the adjustment accuracy, and ensure the accuracy of equidistant cutting.

[0026] A collection frame 5 is slidably connected to the frame 1 below the carrying plate 4. A V-groove 40 and a knife groove 400 are provided on the side of the carrying plate 4 near the equidistant cutting device 6. A V-shaped clamp 41 for positioning straws of different diameters is engaged in the knife groove 400 at the end of the carrying plate 4. In this way, the V-groove 40 and knife groove 400 on the carrying plate 4, as well as the V-shaped clamp 41 at the end, can effectively position straws of different diameters, ensuring the accuracy of the straw's position during the cutting process. The cut straws can fall directly into the collection frame 5 for easy collection and sorting, thus improving production efficiency.

[0027] Working principle: First, the straw is placed on the carrier plate 4, and the V-shaped clamp 41, which is engaged in the cutter groove 400 at the end of the carrier plate 4, positions the straws of different diameters. The carrier plate 4 is connected and fixed to the frame 1 through the dovetail groove 100, and the carrier plate 4 is embedded in the dovetail groove 100. The hydraulic cylinder 2 at the top of the frame 1 drives the cutter base 3, and the guide rod 31 on the cutter base 3 slides along the guide groove 10. The cylinder 62 in the equidistant cutting assembly 6 pushes the linkage push rod 63, and the linkage push rod 63 drives multiple cutter arms 64 to move through the slide groove 630. The connector 641 at one end of the cutter arm 64 slides in the accordion groove 610 of the connecting plate 61 to adjust the distance between the cutter arms 64. At the same time, the sensor 631 reads the value of the scale line 611. Finally, the cutter head 65 completes the equidistant cutting of the straw, and the cut straw falls into the collection frame 5.
