Description

Technical Field

[0001] The invention relates to the technical field of waste collection, and in particular to a waste collection device for non-woven fabric processing. Background Art

[0002] In the production of non-woven fabrics, high-temperature melting, spinning, and steel laying are achieved by meltblowing machines. Generally, meltblowing machines are mainly composed of extruders and web-forming devices. In actual operation, high-speed hot air flow is used to stretch the polymer melt fine stream extruded from the die spinneret hole, thereby forming ultrafine fibers and collecting them on the condensing screen or roller, and at the same time, they are bonded to form meltblown non-woven fabrics. The molten raw materials are ejected through the meltblowing head and finally cooled and formed. At this stage, when the meltblowing machine is working, whenever the equipment is just running or about to stop running, the molten raw materials ejected by the nozzle are uneven, so that the molten raw materials ejected by the nozzle will accumulate on the web-forming device, and the uneven molten raw materials and accumulated materials will affect the quality of non-woven fabrics. Therefore, it is necessary to design a device that can collect uneven molten raw materials. On the one hand, it can improve the product processing quality, and on the other hand, it can also collect waste materials for recycling. Summary of the invention

[0040] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0041] Embodiment 1:

[0042] Reference Figure 1-Figure 10 The present invention proposes a waste collection device for non-woven fabric processing, comprising a waste collection plate 3 arranged outside a nozzle 1 of a spray melt machine, a transfer mechanism for sucking waste, and a drive mechanism for driving the waste collection plate 3 to move. The nozzle in the present invention has a substantially consistent internal structure with that of an existing nozzle, generally including a material channel 102 arranged in the center for conveying molten material, and a material spray port 103 is arranged at the bottom of the nozzle 1, and air channels 101 for cooling air flow are also arranged on both sides of the material channel 102.

[0043] The waste collection plate 3 is an L-shaped plate composed of a collection section 301 and a connection section 302. The collection section 301 is located below the nozzle 1. The collection section 301 is used to receive the waste sprayed by the nozzle 1, and the waste sprayed by the nozzle 1 forms a waste block 18 on the surface of the collection section 301. The connection section 302 and the nozzle 1 are connected by a driving mechanism. The surface of the collection section 301 is smoothed, and its material can be selected from stainless steel, which can avoid excessive adhesion with the waste and inconvenience in separating the waste.

[0044] The transfer mechanism includes a scraping unit and a suction unit, wherein: the scraping unit is used to separate the waste block 18 on the collecting section 301 from the collecting section 301 and break the waste block 18; the suction unit is used to suck away the broken waste block 18.

[0045] The driving mechanism is used to drive the collecting section 301 to move to the scraping unit to separate and break the waste blocks 18 on the collecting section 301 .

[0046] The present invention can collect waste materials during the time period when the nozzle is turned on or off through the above scheme, thereby preventing the waste materials from being sprayed on the non-woven fabric forming plate, and can also collect the waste materials for secondary recycling.

[0047] In this scheme, please refer to Figure 4 The driving mechanism includes a micro push rod 15 installed on the outside of the nozzle and a movable seat 16 connected to the output end of the micro push rod 15, the movable seat 16 and the connecting section 302 are longitudinally slidably connected, and the driving mechanism also includes a guide rod 17 with an angle with the horizontal direction, one end of the guide rod 17 is connected to the nozzle 1, and the connecting section 302 can slide along the inclined direction of the guide rod 17. The guide rod 17 and the housing of the nozzle 1 can be connected by a screw installation. The micro push rod 15 can be controlled by a PLC controller.

[0048] The present invention uses the above structure to make the collecting section 301 tilt and move, so that the waste blocks 18 on the surface thereof can be separated and broken by the scraping unit.

[0049] It should be noted that in this solution, the scraper unit includes a scraper 8 and a scratching knife 9 arranged on one side of the bottom surface of the nozzle, wherein the scratching knife 9 is arranged close to the center of the nozzle 1, and a knife groove for installing the scratching knife 9 is provided on the bottom surface of the nozzle 1, the end of the scraper 8 is arranged obliquely, and the blade of the scraper 8 points to one side of the scratching knife 9, and the other end of the scraper 8 is rotatably connected to the bottom surface of the nozzle 1, and a return spring connected to the scraper 8 is also installed on the bottom surface of the nozzle 1. The initial tilt angle of the scraper 8 can be controlled by the elastic force and length of the return spring.

[0050] In this way, when the collecting section 301 gradually moves, the waste block 18 first contacts the scraper 9 and divides it into several small pieces of waste, and the scraper 8 can then separate the small pieces of waste from the surface of the collecting section, making it convenient for the subsequent suction unit to suck away the waste.

[0051] It is worth mentioning that the blade of the scratching knife 9 is serrated, and both the scraper 8 and the scratching knife 9 are made of stainless steel. When not affected by other external forces, the bottom end height of the scraper 8 is lower than the bottom end height of the scratching knife 9.

[0052] In this solution, the suction unit includes a mounting box 2, a suction fan 27 disposed in the mounting box 2, and a suction pipeline connected to the suction port of the suction fan 27. The suction pipeline includes a suction head 10, an inner tube 11, and a telescopic tube 12, wherein one end of the inner tube 11 is connected to the suction port of the suction fan 27, and the two ends of the telescopic tube 12 are respectively connected to the suction head 10 and the inner tube 11. The end of the suction head 10 can extend out of the mounting box 2 and probe into the space between the scraper 8 and the scraper 9 to suck the material. The mounting box 2 is also provided with an adjustment module for driving the telescopic tube 12 to extend and retract. The suction fan can be implemented by using an existing negative pressure fan, and its specific shape and size are selected according to actual needs.

[0053] The present invention can use the suction head 10 to suck away small pieces of waste material under the negative pressure of the suction fan and transfer them to the installation box 2 for storage.

[0054] As an optional embodiment of the present invention, the adjustment module has two electromagnets 14 capable of generating magnetic force, one of which is connected to the inner wall of the mounting box 2, and the other is mounted on a mounting plate 13, and the mounting plate 13 is connected to the part of the suction head 10 located in the mounting box 2. By controlling the current direction of the electromagnet 14, the direction of action of the magnetic force can be changed, so that the suction head 10 moves back and forth.

[0055] For details, please refer to Fig. 9 A plurality of ear plates 4 are arranged on the outside of the mounting box 2, and the same ear plates 4 are also arranged on the nozzle 1. The ear plates 4 on the mounting box 2 are fixed with connecting screws 6. The ear plates 4 on the nozzle 1 are provided with through holes, and the ends of the connecting screws 6 pass through and are connected with locking nuts 7. A columnar spring 5 is also sleeved on the outside of the connecting screws 6.

[0056] See also Figure 5-Figure 8 As an optimal embodiment of the present invention, a partition 28 is fixed in the installation box 2, and the installation box 2 above the partition 28 is a collection chamber 201, and a waste sorting unit is also arranged in the installation chamber 201. A mounting hole is opened on the partition 28, and the mounting hole is used to install a discharge pipe 29 of a suction fan 27. A notch 25 is also opened on the shell of the installation box 2, and a switch door 26 is installed at the notch 25.

[0057] This solution utilizes a waste sorting unit to facilitate the collection of waste and facilitate centralized processing.

[0058] In order to facilitate the stable operation of the waste sorting unit and effectively collect the waste on one side of the collecting chamber to the other side, an inner wall of the collecting chamber 201 away from the notch 25 is set as an arc segment 32. The waste sorting unit includes a push-pull rod 24 that movably penetrates the installation box 2, a sorting plate movably arranged in the installation chamber 201, and a rack plate 22 fixed in the installation chamber 201. The sorting plate includes a rotating part 19, a sliding part 21 and a connecting shaft 35. The rotating part 19 and the sliding part 21 are rotatably connected by the connecting shaft 35. The sliding part 21 is connected to the push-pull rod 24. A gear 20 is mounted on the outer side of the connecting shaft 35. The gear 20 can mesh with the rack plate 22, and an elastic layer 31 is arranged on the outer side of the arc segment 32. A gap 30 is formed between the elastic layer 31 and the arc segment 32. A spring (not shown) for connecting the elastic layer 31 is installed in the gap 30. The purpose of setting the spring is to make the elastic layer 31 automatically reset, so that the waste can be cleaned more thoroughly by the rotating part 19.

[0059] Reference Figure 6 Before the suction fan 27 is started each time, the push-pull rod 24 is used to pull the sliding part 21 to drive the rotating part 19 to move to the side close to the notch. Due to the meshing action of the gear 20 and the rack plate 22, the rotating part 19 can be driven to rotate 180 degrees in the collection chamber 201, so that the waste located above the discharge pipe 29 can be fully pushed to the other side of the collection chamber 201. When the gear 20 and the rack plate 22 are separated, the rotating part just rotates 180 degrees, so that both sides of the rotating part 19 can contact the inner wall of the collection chamber, and the waste can be pushed to the notch by the rotating part for cleaning. In this solution, a connecting rod 33 is fixed in the collection chamber 201, and the end of the connecting rod 33 is used to install the rack plate 22.

[0060] In order to realize the automated work, an electric push rod for driving the push-pull rod 24 to work back and forth can be arranged on the outside of the installation box. In this way, the controller can be used to control the electric push rod to drive the push-pull rod to work automatically, saving manpower and material resources.

[0061] The present invention can prevent the waste material sucked into the collecting chamber 201 from being blocked at the discharge pipe 29 through the above-mentioned design, so as to ensure the normal operation of the equipment.

[0062] As a further improvement of the above scheme, rolling elements 34 are installed on both side ends of the rotating part 19, and the rolling elements 34 can contact the inner wall of the installation cavity 201 and the elastic layer 31, and a baffle 23 is also rotatably connected in the installation cavity 201, and a return spring is connected between the baffle 23 and the inner wall of the installation cavity 201. The purpose of setting the baffle 23 in this scheme is to prevent the waste from being pushed back to the original position by the rotating rotating part. Therefore, the baffle 23 can stop the waste and prevent the waste from continuing to move to the side close to the discharge pipe, so that the waste can be cleaned more fully and thoroughly.

[0063] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
