[0002] As the name implies, a fluff machine is a machine designed for producing fluff. It is commonly used in the textile industry and waste recycling industry. According to its literal meaning, the fluff machine is a broad term, which is divided into sweeping machines, cutting machines, beating machines, etc. according to the production process. Most textile fluff workshops will have a separate cutting room. The cutting machine is located in the cutting room. It is mainly used to cut the fluff material (recycled strip material head). According to the recycling needs, the narrower the cut material, the greater the fluff precision will be, the closer the obtained product is to wool, and the finer the fluff will be.

The free end of the attached hopper is located in the discharge hopper, and the attached hopper can rotate upward around the hinge shaft. A leakage port is opened at one end of the attached hopper connected to the hinge shaft. When the attached hopper rotates downward into the discharge hopper, the leakage port falls on the bottom surface of the inner cavity of the discharge hopper, and the leakage port covers the bottom surface of the inner cavity of the discharge hopper.

DETAILED DESCRIPTION

[0032] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0033] In one embodiment, if Figure 1-Figure 10 As shown:

[0034] The present embodiment provides a fluffing machine, comprising a main body 1, a lower die 2 fixed on the top of the main body 1, a guide column 3 fixed on the lower die 2 and vertically upward, an upper die 4 installed on the lower die 2 through the guide column 3, and a connecting seat 5 installed on the top surface of the upper die 4. In actual use, the connecting seat 5 is connected to the head of the punching machine, the lower die 2 is fixed on the working platform of the punching machine, and the upper die 4 is fixed to the head by the connecting seat 5. When the head is punching, the upper die 4 is lowered relative to the lower die 2 through the connecting seat 5; Figure 2 As shown, a material cavity 6 communicating front to back is provided between the upper mold 4 and the lower mold 2, and the front and rear ends of the material cavity 6 are communicated with the front and rear surfaces of the upper mold 4 and the lower mold 2. A discharge port 7 is provided on the front side of the material cavity 6, and a feed pipe 8 is connected between the rear ends of the upper mold 4 and the lower mold 2 and the discharge port 7. The fluff material flows into the material cavity 6 from the feed pipe 8 and is discharged through the discharge port 7. When the material is discharged to the discharge port 7, the upper mold 4 carries a cutter 9 to punch and cut the material being discharged, and the cut fluff material strips (strip-shaped fluff material) fall into the discharge hopper 10 and are finally discharged outward through the discharge hopper 10. In actual use, a material bag will be installed at the bottom of the discharge hopper 10 to receive the fluff material strips. The punching speed of the punch head is adjusted, but the feeding speed of the feeding device into the feed pipe 8 is not changed, so that the number of times the cutter 9 punches the material per unit time becomes more, so that the obtained fluff material strips are narrower and finer; the discharge hopper 10 is tilted downward from the front of the lower die 2 to facilitate discharge.

[0035] In addition to the above functions, Figure 1 , Figure 5 , Figure 6 as well as Figures 8 to 10As shown, a secondary processing mechanism 11 is arranged in the discharge hopper 10, and the secondary processing mechanism 11 includes a transmission shaft 12 installed in the discharge hopper 10, and also includes a grinding wheel assembly 13 fixed to the transmission shaft 12 and located in the discharge hopper 10, the grinding wheel assembly 13 is composed of a plurality of grinding wheel units 131, and the plurality of grinding wheel units 131 are distributed in the discharge hopper 10 along the width direction of the discharge hopper 10 through the transmission shaft 12; the outer end of the transmission shaft 12 passes through the outside of the discharge hopper 10, and the secondary processing mechanism 11 also includes a transmission connection between the outer end of the transmission shaft 12 and the The driving mechanism 14 between the upper molds 4, that is, when the upper mold 4 carries the cutter 9 to perform a punching action on the fluff material being discharged through the discharge port 7, the upper mold 4 will also rotate the transmission shaft 12 through the driving mechanism 14 under the action of the upper mold 4, and the transmission shaft 12 will rotate the grinding wheel assembly 13. Since the grinding wheel assembly 13 is composed of a plurality of grinding wheel units 131, and is distributed and rotated in the width direction of the discharge hopper 10, when the transmission shaft 12 rotates with these grinding wheel units 131, the fluff material strips falling into the discharge hopper 10 will be crushed into fluff. It can be seen from this that after the strip-shaped fluff material is cut into fluff material strips by this device, the fluff material strips can be secondary-rolled into finer fluff while being discharged from the discharge hopper 10. Two functions are set on the same device, and these two functions complete two actions progressively. In particular, the power generated when the upper mold 4 carries the cutter 9 to cut the material into strips is applied to the preparation of the fluff. Therefore, in order to obtain finer fluff, no additional power is required, and no additional other equipment is required. It can not only meet two production needs, but also save costs.

[0036] like Figures 1 to 9 As shown, hinge shafts 17 are installed on both sides of the discharge port 7, and an attached hopper 18 is installed on the front side of the discharge port 7 through the hinge shaft 17. The free end of the attached hopper 18 is located in the discharge hopper 10, and the attached hopper 18 can rotate up and down around the hinge shaft 17. One end of the attached hopper 18 connected to the hinge shaft 17 is provided with a leak 19. When the attached hopper 18 rotates downward into the discharge hopper 10, the leak 19 falls on the bottom surface of the inner cavity of the discharge hopper 10, and the leak 19 covers the bottom surface of the inner cavity of the discharge hopper 10. When the attached hopper 18 rotates upward, the leak 19 leaves the bottom surface of the inner cavity of the discharge hopper 10 upward, and makes the discharge port 7 and the leak 19 communicate with the bottom surface of the inner cavity of the discharge hopper 10. There are drop grooves 28 on both sides of the discharge hopper 10. When the attached hopper 18 rotates downward into the discharge hopper 10, it brings the two ends of the transmission shaft 12 into the drop grooves 28 on both sides respectively. A bearing 26 is installed at both ends of the transmission shaft 12. When the two ends of the transmission shaft 12 fall into the drop grooves 28 on both sides, the bearings 26 are respectively stuck in the drop grooves 28 on the same side.

[0037] In summary, the user can choose whether to completely rotate the attachment hopper 18 downward into the discharge hopper 10 according to different needs (needing fine fluff or only needing fluff strips). When the attachment hopper 18 is completely rotated downward into the discharge hopper 10, the leak 19 will rotate with the attachment hopper 18 to cover the bottom surface of the inner cavity of the discharge hopper 10, and at the same time, the transmission shaft 12 in the attachment hopper 18 will carry all the roller units 131 distributed in the discharge hopper 10, and At the discharge position of the discharge port 7, when the upper die 4 carries the cutter 9 to drop the fluff strips cut from the material into the discharge hopper 10, it will slide along the discharge hopper 10 to the first row of the grinding wheel unit 131. Each time the upper die 4 punches and cuts, the driving rod 22 will be lowered once, and the driving rod 22 will bring the ratchet 23 down once. According to the mechanical principle of the ratchet, when the ratchet 23 drops into the intermittent groove 24, it will provide a push to the intermittent groove 24, and the intermittent groove 24 will be pushed by the ratchet 23. The intermittent groove 24 drives the wheel disc 21 to rotate an angle, and rotates the next intermittent groove 24 to the position where the previous intermittent groove 24 is triggered by the pawl 23. According to the working principle of the punch press head, the upper mold 4 will rise again after each punching and cutting action, and the pawl 23 will rise again with the driving rod 22. According to the mechanical principle of the pawl, when the driving rod 22 rises, in addition to rising with the pawl 23 at the same time, the pawl 23 will also rotate outward from the intermittent groove 24, and automatically separate from the intermittent groove 24 as the driving rod 22 rises. When the upper mold 4 punches and cuts again with the cutter 9, it will bring the driving rod 22 down again, and the driving rod 22 brings the pawl 23 down again and gets stuck in the next rotated intermittent groove 24, and so on. The wheel disc 21 is triggered to rotate intermittently with the transmission shaft 12, and the fluff strips cut into the discharge hopper 10 by the transmission shaft 12 are crushed into finer fluff for the second time. When it is not necessary to make fine fluff, the attached hopper 18 is rotated upward around the hinge shaft 17 to separate the attached hopper 18 from the bottom surface of the inner cavity of the discharge hopper 10. At this time, the leak 19 provided on the hinged end of the attached hopper 18 will be opened, so that the discharge port 7 is connected with the leak 19, and at the same time, it is directly connected with the discharge hopper 10 through the leak 19. After the material is cut by the cutter 9 at the discharge port 7, it passes through the leak 19 and falls into the discharge hopper 10 and is discharged directly. At this time, fluff material strips (strip-shaped fluff material) are directly obtained, which can be used more flexibly according to different production needs.

[0038] like Fig. 9As shown, the driving mechanism 14 also includes a driven sprocket 25 fixed to the outer end of another transmission shaft 12. The driven sprocket 25 and the driving sprocket 20 are driven by a chain (the chain is omitted in the prior art), so that the two rows of grinding wheel units 131 can rotate simultaneously. After being processed by the upper row of grinding wheel units 131, the materials enter the next row of grinding wheel units 131 to wait for processing. When the upper row of grinding wheel units 131 are driven by the wheel disc 21 to rotate and grind again, the driven sprocket 25 will drive the next transmission shaft 12 to rotate through the chain transmission relationship, and the next transmission shaft 12 will drive the next row of grinding wheel units 131 to perform fine processing on the materials waiting to be processed last time.

[0039] As a further preferred embodiment, there are two transmission shafts 12, and the two transmission shafts 12 are adjacently distributed in the discharge hopper 10. Each transmission shaft 12 is equipped with a row of grinding wheel units 131. The two rows of grinding wheel units 131 are arranged in a row. Figure 7 The arrangement is spaced as shown, that is, the first row of grinding wheel units 131 and the second row of two grinding wheel units 131 are staggered, so that the material is rolled and kneaded by the first row of grinding wheel units 131, and then enters the second row of grinding wheel units 131 for rolling and kneading, increasing the area processed into fine fluff, realizing secondary processing and improving efficiency.

[0040] like Figure 3 As shown, a cover plate 27 is fixed in front of the attached hopper 18, and all the roller units 131 are covered in the cover plate 27. When the roller units 131 roll and rub the material strips into fluff, the fluff dust generated is covered by the cover plate 27 and confined in the attached hopper 18, and flows to the discharge hopper 10 through the attached hopper 18, and then the material is discharged uniformly by the discharge hopper 10, which is environmentally friendly and can also reduce waste.

[0041] like Figure 1 , Figure 3 As shown, a forward seat 15 is fixed to the front of the main body 1, and the forward seat 15 is located at the rear side of the discharge hopper 10. The top surface of the forward seat 15 is provided with a chamfered surface 16, and the chamfered surface 16 is close to the bottom surface of the discharge hopper 10. The bag mouth of the packaging bag is sleeved on the bottom end of the discharge hopper 10, and the part of the packaging bag close to the bag mouth is restricted by the bottom surface of the discharge hopper 10 on the chamfered surface 16, so that the bag mouth can be kept open when discharging materials to the bag mouth, which is convenient for receiving materials.

[0042] The present invention also provides a method for using a fluffing machine, which is applicable to the fluffing machine as described above, and comprises the following steps:

[0043] Step S01, fixed installation: fix the connection seat 5 on the punch head, use the punch head to provide power to the upper die 4; fix the lower die 2 on the workbench of the punch; connect the rear end of the feed pipe 8 to the feeding device;

[0044] Start the punch press, and the punch head brings the upper die 4 up and down along the guide pillar 3 to ensure that the upper die 4 moves smoothly relative to the lower die 2;

[0045] Step S02, feeding the strip-shaped fluff material into the feed pipe 8 through the feeding device, and the strip-shaped fluff material is cut into pieces by the cutter 9 while being discharged from the discharge port 7;

[0046] Step S03, according to production needs, the attached hopper 18 is rotated downward to make the attached hopper 18 enter the discharge hopper 10, and at the same time, the bottom end of the pawl 23 enters the intermittent groove 24. When the upper mold 4 is punching with the cutter 9, the pawl 23 is brought into the intermittent groove 24 and the wheel disc 21 is pushed to rotate intermittently. The wheel disc 21 drives the transmission shaft 12 to rotate intermittently, and the transmission shaft 12 drives the grinding wheel unit 131 to rotate intermittently, and the material that slides into the discharge hopper 10 after cutting is crushed into fluff and then discharged through the discharge hopper 10.

[0047] It should be further explained that the pawl used in the present invention is only a schematic structure in the figure, which is often used in intermittent motion occasions of mechanical transmission. It is composed of a pawl body, a pin shaft, a spring and other components. Each time the pawl body pushes the rotating workpiece to rotate, the pawl body can rotate back to its original position. Then, when the pawl body contacts the rotating workpiece again, it will automatically form a dead point to push the workpiece to rotate. Since this is an existing mature technology in the mechanical field, the present invention briefly mentions it and does not need to be elaborated, so it is hereby explained.

[0048] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0049] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
