Description

Technical Field

[0001] This utility model relates to the field of short-cutting device technology, specifically a composite short fiber short-cutting device. Background Technology

[0002] Short fibers, also known as cut fibers, are chemical fiber bundles that have been cut or broken into fibers of length equivalent to various natural fibers. The definition of short fibers is generally 35–150 mm in length. Based on the specifications of natural fibers, they can be classified into cotton-type, wool-type, carpet-type, and medium-length short fibers.

[0003] After the composite short fibers are cut, they need to undergo a material removal process, which currently still relies on manual operation. This not only increases labor costs, but also poses a high safety risk as the fibers are very easy to pierce the skin during the process and are difficult to remove. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A composite short fiber chopped device includes a cutting mechanism, a pressing mechanism, a blowing mechanism, and a pushing mechanism. The cutting mechanism includes a support frame, a feeding platform installed inside the support frame, a hydraulic cylinder 1 movably suspended above the feeding platform, and a cutter connected between the support frame and the hydraulic cylinder 1. The pressing mechanism includes a hydraulic cylinder 2 vertically penetrating the top of the support frame, a pressure plate located on one side of the cutter and connected to the movable end of the hydraulic cylinder 2. The blowing mechanism includes two side plates installed on the front and rear sides of the pressure plate, a plate body rotatably installed between the two side plates, two torsion springs connected between the side plates and the plate body, and a fan installed inside the plate body. The pushing mechanism includes a plastic sheet connected to the outer end of the plate body, two ropes movably penetrating the top of the support frame and connected to the fan, a horizontal plate connected between the two ropes, and a rubber column movably sleeved on the outside of the ropes. The bottom end of the rubber column is fixed to the top of the support frame, and the top end of the rubber column is attached to the bottom of the horizontal plate.

[0007] By adopting the above technical solution, after the cutter finishes cutting the short fibers, the two moving ends of the hydraulic cylinder retract, the rope relaxes the plate, and at this time, the torsion spring drives the plate and the plastic sheet to flip downwards. The plastic sheet then scrapes the short fibers off the feeding platform. At the same time, the fan starts to ensure that the short fibers on the feeding platform can fall completely into the receiving box, eliminating the need for manual intervention. This reduces the cost of material collection and eliminates safety hazards.

[0008] In a preferred embodiment, the present invention can be further configured such that two torsion springs are located on both sides of the plate, and the diameter of the torsion springs is smaller than the thickness of the plate.

[0009] In a preferred embodiment, the present invention can be further configured such that two ropes are vertically symmetrical about the fan, and the ropes are made of multiple nylon filaments bound together.

[0010] In a preferred embodiment, the present invention can be further configured such that: a material blocking mechanism is provided on the outside of the support frame, the material blocking mechanism including two plastic rods fixed to one side of the support frame, a support rod fixed to the front side of the support frame, and a baffle cloth movably sleeved on the outside of the support rod.

[0011] In a preferred embodiment, the present invention can be further configured such that: a receiving box is movably provided at the bottom of the support frame, the receiving box is located between two shaping rods, and the top of the receiving box is in contact with the bottom of the feeding platform.

[0012] In a preferred embodiment, the present invention can be further configured such that: two baffles are fixedly connected to the top of the feeding platform, and the distance between the two baffles is greater than the width of the pressure plate.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, after the cutter finishes cutting the short fibers, the two movable ends of the hydraulic cylinder retract, the rope relaxes the plate, and at this time, the torsion spring drives the plate and the plastic sheet to flip downwards. The plastic sheet then scrapes the short fibers off the feeding platform. At the same time, the fan starts to ensure that the short fibers on the feeding platform can fall completely into the receiving box, eliminating the need for manual intervention, which reduces the cost of material collection and eliminates safety hazards.

[0015] 2. In this utility model, when the receiving box collects the cut short fibers, the baffle is stretched so that it is arranged around the two plastic rods, which can prevent the short fibers blown by the wind from flying around. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a composite short fiber shaving device.

[0032] Example 1:

[0033] Combination Figure 1-5 As shown, the present invention provides a composite short fiber shaving device, including a cutting mechanism 100, a pressing mechanism 200, a blowing mechanism 300, and a pushing mechanism 400. The cutting mechanism 100 includes a support frame 110, a feeding platform 120 installed inside the support frame 110, a hydraulic cylinder 130 movably suspended on the top of the feeding platform 120, and a cutter 140 connected between the support frame 110 and the hydraulic cylinder 130.

[0034] The clamping mechanism 200 includes a second hydraulic cylinder 210 that extends vertically through the top of the support frame 110 and a pressure plate 220 located on one side of the cutter 140 and connected to the movable end of the second hydraulic cylinder 210.

[0035] The blowing mechanism 300 includes two side plates 310 installed on the front and rear sides of the pressure plate 220, a plate body 320 rotatably installed between the two side plates 310, two torsion springs 330 connected between the side plates 310 and the plate body 320, and a fan 340 installed inside the plate body 320.

[0036] The material pushing mechanism 400 includes a plastic sheet 410 connected to the outer end of the plate 320, two ropes 420 that movably pass through the top of the support frame 110 and are connected to the fan 340, a horizontal plate 430 connected between the two ropes 420, and a rubber column 440 that is movably sleeved on the outside of the ropes 420. The bottom end of the rubber column 440 is fixed to the top of the support frame 110, and the top end of the rubber column 440 is attached to the bottom of the horizontal plate 430.

[0037] Furthermore, two torsion springs 330 are located on both sides of the plate 320. The diameter of the torsion springs 330 is smaller than the thickness of the plate 320. The size design of the torsion springs 330 allows them to firmly bind the plate 320.

[0038] Furthermore, the two ropes 420 are vertically symmetrical about the fan 340. The ropes 420 are made of multiple nylon filaments bundled together. The structural design of the ropes 420 can reduce the probability of rope breakage.

[0039] Furthermore, two baffles 700 are fixedly connected to the top of the feeding platform 120. The distance between the two baffles 700 is greater than the width of the pressure plate 220. The baffles 700 can prevent short fibers from falling to the outside of the receiving box 600.

[0040] Example 2:

[0041] Combination Figure 1 and Figure 5 As shown, based on Embodiment 1, the support frame 110 is provided with a material blocking mechanism 500 on the outside. The material blocking mechanism 500 includes two plastic rods 510 fixed to one side of the support frame 110, a support rod 520 fixed to the front side of the support frame 110, and a baffle 530 movably sleeved on the outside of the support rod 520. When the receiving box 600 collects the cut short fibers, it stretches the baffle 530 so that the baffle 530 is arranged around the two plastic rods 510, which can prevent the short fibers blown by the wind from flying around.

[0042] Example 3:

[0043] Combination Figure 1 and Figure 5As shown, in the above embodiment, a receiving box 600 is movably provided at the bottom of the support frame 110. The receiving box 600 is located between the two shaping rods 510. The top of the receiving box 600 is attached to the bottom of the feeding platform 120. The receiving box 600 provides conditions for the unified collection of short fibers.

[0044] The working principle and usage process of this utility model are as follows: Short fibers are placed on the feeding platform 120, and hydraulic cylinders 130 and 210 are started simultaneously. The pressure plate 220 then cooperates with the feeding platform 120 to first press the short fibers, and then the cutter 140 cuts the short fibers. During this process, the plate 320 descends with the pressure plate 220, but is restricted by the tension of the rope 420, and its outer end is forced to tilt upward, causing the torsion spring 330 to deform. When the movable end of the hydraulic cylinder 210 retracts, the rope 420 relaxes the plate 320. At this time, the torsion spring 330 drives the plate 320 and the plastic sheet 410 to flip downward. The plastic sheet 410 then scrapes the short fibers off the feeding platform 120. At the same time, the fan 340 starts to ensure that the short fibers on the feeding platform 120 can fall completely into the receiving box 600.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
