Description

Technical Field

[0001] The utility model relates to straw processing equipment, in particular to a novel degradable material cutting device. Background Art

[0002] At present, a Chinese patent with publication number CN115431338A discloses a straw slitting and processing device, including a rotary conveying unit, which is used to convey the straws along a conveying path and make the straws rotate continuously during the conveying process.

[0003] It also includes a cutting unit, which is provided with a first rotating cutter disc and a second rotating cutter disc beside the conveying path, the first rotating cutter disc is provided with a first tool holder, the first tool holder is provided with a first end and a second end, the first end is provided with a first blade, the second end is provided with a rotatable drill bit, the cutting direction of the first blade is perpendicular to the conveying path, the second rotating cutter disc is provided with a second tool holder, the second tool holder is installed with a second blade, and the cutting direction of the second blade is inclined with respect to the conveying path.

[0004] When the straw moves along the conveying path, the first rotating cutter disc drives the first blade on the first end to tangentially cut the conveying path to cut the straw, and the first rotating cutter disc drives the drill bit on the second end to move to the conveying path to contact the outer wall of the straw. Under the action of the spiral conveying unit, the straw rotates forward to form a thread groove, and the second rotating cutter disc drives the second blade on the second tool holder to tangentially cut the conveying path to cut the straw.

[0005] However, when the above-mentioned cutting device is used to cut the straw, the cutting unit can only cut off a section of the straw in one operation, which has the defect of low cutting efficiency. Summary of the invention

[0006] In view of this, the purpose of the utility model is to provide a novel biodegradable material cutting device, which has the advantage of higher cutting efficiency.

[0007] In order to solve the above technical problems, the technical solution of the utility model is: a new type of biodegradable material cutting device, comprising a cutting bracket, a mounting groove is opened on the front side of the cutting bracket, a transmission shaft is rotatably connected in the mounting groove, and the transmission shaft extends along the conveying direction of the straw to be cut, and the outer fixed sleeve of the transmission shaft is provided with two cutting blades, and the edges of the two cutting blades protrude from the notch of the mounting groove; a driving motor is arranged on the left side of the cutting bracket, and the output shaft of the driving motor is connected to the transmission shaft through a coupling; a limiting baffle is arranged at the left edge of the cutting bracket, and the limiting baffle is used to interfere with the end of the straw to be cut, and the spacing between the limiting baffle and the cutting blade on the left is equal to the spacing between the two cutting blades.

[0008] According to the above technical solution, when in use, the straw conveying device drives the straw to move to one side of the cutting device until the straw contacts the limit baffle. At the same time, the driving motor drives the cutting blade to rotate through the driving shaft, and when the cutting blade rotates to contact the straw, the cutting blade can cut the straw. Since two cutting blades are arranged side by side on the transmission shaft, and the spacing between the limit baffle and the left cutting blade is equal to the spacing between the two cutting blades, two straws can be obtained when the transmission shaft rotates one circle, which has the advantage of high cutting efficiency.

[0009] Preferably, a storage groove is opened on the right side of the limit baffle, a rubber baffle is arranged in the storage groove, the right side of the rubber baffle is flush with the right side of the limit baffle, and an arc-shaped rubber buffer plate is arranged at the top edge of the right side of the rubber baffle, and the arc-shaped rubber buffer plate is used to fit with the end of the straw to be cut.

[0010] With the above technical solution, when the straw hits the limiting baffle, the arc-shaped rubber buffer plate contacts the outer wall of the straw to limit the straw, so that the straw is not easy to move in the opposite direction after hitting the rubber baffle. The rubber baffle can be used to protect the end of the straw, so that the end of the straw is not easy to deform.

[0011] Preferably, a curved rubber guide plate is provided on the right top edge of the curved rubber buffer plate, and the inner edge of the curved rubber guide plate gradually increases from left to right.

[0012] With the above technical solution, the inner edge of the arc-shaped rubber guide plate gradually increases from left to right, which can be used to guide the straw to pass through under the arc-shaped rubber buffer plate, so that the straw is less likely to collide with the end of the arc-shaped rubber buffer plate and stop moving.

[0013] Preferably, a plurality of arc-shaped plug-in grooves are provided on the right side of the rubber baffle plate, and the plurality of arc-shaped plug-in grooves are arranged concentrically, and an arc-shaped plug-in block is provided on the left side of the arc-shaped rubber buffer plate, and the arc-shaped plug-in block is plugged and fixed in the arc-shaped plug-in groove.

[0014] Through the above technical solution, the arc-shaped plug-in groove and the arc-shaped plug-in block cooperate with each other to connect the rubber baffle plate with the arc-shaped rubber buffer plate, making the disassembly and assembly of the arc-shaped rubber buffer plate more convenient.

[0015] Preferably, a support frame is provided at the right edge of the cutting bracket, a support tube is provided on the top of the support frame, and the straw to be cut passes through the support tube.

[0016] Through the above technical solution, the support tube can be used to support the straw, so that the end of the straw is not likely to droop downward, and the accuracy of straw cutting is not easily affected.

[0017] Preferably, the support tube includes a fixed flap fixedly connected to the support frame and a movable flap movably arranged on the top of the fixed flap, one end of the movable flap is hinged to the fixed flap, and the other end of the movable flap is clamped to the fixed flap.

[0018] Through the above technical solution, one end of the movable flap is hinged to the fixed flap, and the other end of the movable flap is clamped to the fixed flap. In this way, you only need to open the movable flap to easily put the straw between the movable flap and the fixed flap, which makes the operation more convenient.

[0019] Preferably, a mounting plate is provided at the bottom of the fixed flap, and screws are provided on both sides of the mounting plate, and the two screws press and fix the mounting plate to the support frame.

[0020] Through the above technical solution, the screws press and fix the mounting plate to the support frame, so as to fix the fixed flap to the support frame, making the disassembly and assembly of the fixed flap more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
