[0041] Below is the attached figure Figures 1 to 3The technical solution of the utility model is further illustrated through specific implementation methods.

[0042] like Figure 1-3 As shown, a flocking production line includes:

[0043] Unwinding mechanism 1, the unwinding mechanism 1 is used to unwind the hot melt adhesive tape;

[0044] a first coating mechanism 2, which is used to coat a bridging agent onto the front surface of the hot melt adhesive sheet discharged by the unwinding mechanism 1;

[0045] a first heating mechanism 3, the first heating mechanism 3 being used to heat the hot melt adhesive cloth coated with a bridging agent;

[0046] A second coating mechanism 4, the second coating mechanism 4 is used to apply silica gel to the front surface of the hot melt adhesive cloth coated with the bridging agent;

[0047] A flocking machine 5, which is used to flock the front surface of the hot melt adhesive cloth coated with silicone;

[0048] A second heating mechanism 6, the second heating mechanism 6 is used to heat the hot melt adhesive cloth after flocking;

[0049] a lint removal mechanism 7, the lint removal mechanism 7 being used to recover excess lint on the surface of the hot melt adhesive sheet heated by the second heating mechanism 6;

[0050] The winding mechanism 8 is used to wind up the hot melt adhesive cloth processed by the lint removal mechanism 7 .

[0051] During flocking, a bridging agent is first applied to the upper surface of the hot-melt adhesive tape and then heated and dried to allow the bridging agent to fully react with the hot-melt adhesive tape. Silica gel is then applied to the upper surface of the hot-melt adhesive tape and heated to allow the silica gel and the hot-melt adhesive tape to be firmly bonded together with the aid of the bridging agent. Silica gel is then flocked on the upper surface of the silica gel, and after flocking, it is heated and dried to ensure that the fluff is firmly bonded to the silica gel. Excess fluff on the surface of the hot-melt adhesive tape is then removed by a de-linting mechanism 7, and finally recycled. Production is carried out through a production line consisting of multiple devices, without the need to circulate through multiple workshops, thereby improving production efficiency.

[0052] like Figure 1 As shown, the first coating mechanism 2 includes a frame 21, a conveying roller 22, a material carrying plate 23 and a lifting assembly 24;

[0053] The conveying roller 22 is rotatably mounted on the frame 21, and the carrying plate 23 is fixedly mounted on the frame 21. The carrying plate 23 is located on one side of the conveying roller 22 and is spaced apart from the conveying roller 22. Limiting plates 231 are symmetrically provided on both sides of the top of the carrying plate 23. One side of the two limiting plates 231 is closely attached to the conveying roller 22.

[0054] The lifting assembly 24 is fixedly mounted on the frame 21 , and a scraper 25 is installed at the lifting end of the lifting assembly 24 . The scraper 25 is located above the conveying roller 22 . The hot melt adhesive tape is wound around the conveying roller 22 and passes through the gap between the loading plate 23 and the scraper 25 and the conveying roller 22 in sequence.

[0055] Specifically, the bridging agent is stored on the carrier plate 23. When the hot melt adhesive tape is transported by the conveying roller 22, it passes through the gap between the carrier plate 23 and the conveying roller 22, thereby coating the bridging agent on the upper surface of the hot melt adhesive tape. Then, when it passes through the gap between the scraper 25 and the conveying roller 22, the scraper 25 scrapes off the excess bridging agent, and the lifting component 24 drives the scraper 25 to rise and fall, thereby adjusting the distance between the scraper 25 and the conveying roller 22, thereby adjusting the thickness of the bridging agent coated on the upper surface of the hot melt adhesive tape.

[0056] like Figure 3 As shown, the second coating mechanism 4 has the same structure as the first coating mechanism 2 .

[0057] Specifically, the second coating mechanism 4 has the same structure as the first coating mechanism 2 , which can reduce the types of devices used in the production line and facilitate operation and maintenance.

[0058] like Figure 2 As shown, the first heating mechanism 3 and the second heating mechanism 6 are tunnel furnaces.

[0059] like Figure 1 As shown, an observation box 9 is provided between the flocking machine 5 and the second heating mechanism 6. The observation box 9 is a hollow structure. A first feed port and a first discharge port connected to the interior of the observation box 9 are respectively provided on opposite sides of the observation box 9. An observation port is provided at the top of the observation box 9.

[0060] Specifically, the observation box 9 is provided to facilitate the user to observe the flocking condition of the upper surface of the hot melt adhesive tape, thereby ensuring the production quality.

[0061] like Figure 1 As shown, the lint removal mechanism 7 includes a collection box 71 and a negative pressure recovery component 72;

[0062] The collecting box 71 is a hollow structure. A second feed port 711 and a second discharge port 712 are respectively provided at the top of the collecting box 71, which are connected to the interior of the collecting box 71. A cleaning component 73 is provided inside the collecting box 71. The hot melt adhesive sheet enters the collecting box 71 from the feed port 711 and comes out from the discharge port 712 after contacting the cleaning end of the cleaning component 73. The cleaning component 73 is used to sweep excess fluff on the surface of the hot melt adhesive sheet into the collecting box 71.

[0063] The recovery end of the negative pressure recovery component 72 is connected to the interior of the collection box 71 , and the negative pressure recovery component 72 is used to suck away the fluff in the collection box 71 .

[0064] Specifically, the hot melt adhesive tape passes through the collecting box 71 and contacts the cleaning end of the cleaning component 73 inside the collecting box 71, so that the excess fluff on the surface of the hot melt adhesive tape is swept into the collecting box by the cleaning end of the cleaning component 73, and then the air in the collecting box is extracted by the negative pressure recovery mechanism 72, so that the fluff in the collecting box 71 is extracted. By cleaning with the cleaning component 73, the excess fluff on the surface of the hot melt adhesive tape can be swept into the collecting box 1, avoiding the fluff from remaining on the surface of the hot melt adhesive tape, so that the device has a better recovery effect.

[0065] like Figure 1 As shown, the cleaning assembly 73 includes a first cleaning assembly 731 and a first synchronous driving assembly;

[0066] The first cleaning component 731 includes at least two first brush rollers 7311 and at least one second brush roller 7312. The first brush roller 7311 and the second brush roller 7312 are rotatably installed inside the collection box 1. The first synchronous drive component is used to drive the first brush roller 7311 and the second brush roller 7312 to rotate synchronously. The first brush roller 7311 is used to clean the upper surface of the hot melt adhesive tape, and the second brush roller 7312 is used to clean the lower surface of the hot melt adhesive tape.

[0067] Specifically, flocking is performed on the upper surface of the hot melt adhesive tape, so at least two first brush rollers 7311 are required to clean the upper surface of the hot melt adhesive tape to sweep away excess fluff. In order to prevent the swept fluff from adhering to the lower surface of the hot melt adhesive tape, the second brush roller 7312 is also required to clean the lower surface of the hot melt adhesive tape.

[0068] like Figure 1 As shown, it also includes a second cleaning component 732 and a second synchronous drive component. The structure of the second cleaning component 732 is consistent with that of the first cleaning component 731, and the structure of the second synchronous drive component is consistent with that of the first synchronous drive component.

[0069] Specifically, the second cleaning component 732 can be used to perform a second cleaning on the hot melt adhesive tape, thereby improving the lint removal effect of the device.

[0070] like Figure 1 As shown, the negative pressure recovery assembly 72 includes a first recovery bin 721, a second recovery bin 722 and a negative pressure blower;

[0071] The first recovery bin 721 is located between the first cleaning assembly 731 and the first brush rollers 7311 of the second cleaning assembly 732. The opposite side walls of the first recovery bin 721 are provided with a plurality of first through holes, and the plurality of first through holes are arranged in a one-to-one correspondence with the plurality of first brush rollers 7311.

[0072] The second recovery bin 722 is located above the first cleaning assembly 731 and the second brush roller 7312 of the second cleaning assembly 732. A second through hole corresponding to the second brush roller 7312 is opened at the bottom end of the second recovery bin 722.

[0073] The suction end of the negative pressure fan is connected to the interior of the first recovery bin 721 and the second recovery bin 722 through pipelines respectively;

[0074] The opposite side walls of the first recovery bin 721 are respectively provided with baffles 7211, and the side walls of each baffle 7211 are installed with multiple partitions 7212. The side of the multiple partitions 7212 away from the baffle 7211 is against the inner wall of the collection box 71, and a recovery chamber 7213 is formed between every two adjacent partitions 7212, the collection box 71 and the baffle 7211. Several first brush rollers 7311 are respectively located in the corresponding recovery chambers 7213, and several first through holes are respectively located in the corresponding recovery chambers 7213.

[0075] Specifically, the negative pressure fan is started, and the fluff cleaned by the first brush roller 7311 of the first cleaning component 731 and the second cleaning component 732 will enter the first recovery bin 721 through the first through hole, and the fluff cleaned by the second brush roller 7312 of the first cleaning component 731 and the second cleaning component 732 will enter the second recovery bin 722 through the second through hole. Then the cleaned fluff enters the pipeline through the first recovery bin 721 and the second recovery bin 722 respectively to complete the recovery.

[0076] It is worth noting that the first brush roller 7311 is arranged in the recovery chamber 7213, so that the fluff swept by the first brush roller 7311 is located in the recovery chamber 7213, making it easier for the fluff to enter the first recovery bin 721 through the first through hole.

[0077] It is also worth mentioning that the first recycling bin 721 and the second recycling bin 722 can prevent the cleaned fluff from accumulating in the collection box 71, facilitate the recycling of the fluff, and prevent the cleaned fluff from re-attaching to the hot melt tape.

[0078] Furthermore, a third through hole 7221 is provided on the side wall of the second recovery bin 722. Through the third through hole 7221, the fluff cleaned from the collection box 71 can enter the second recovery bin 722 through the third through hole 7221, thereby preventing the cleaned fluff from accumulating in the collection box 71.

[0079] like Figure 1 As shown, it also includes a correction mechanism 10 arranged between the unwinding mechanism 1 and the first coating mechanism 2, between the first heating mechanism 3 and the second coating mechanism 4, between the second heating mechanism 6 and the lint removal mechanism 7, and between the lint removal mechanism 7 and the winding mechanism 8. The correction mechanism 10 is used to correct the hot melt adhesive tape.

[0080] Specifically, the deviation-correcting mechanism 10 can prevent the hot-melt adhesive tape from deviating during long-distance transportation, thereby preventing the quality of the produced product from being affected.

[0081] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention.
