Description

Technical Field

[0001] The utility model belongs to the technical field of new fiber and composite material preparation, and particularly relates to a double-station felt double-sided broken needle removing system. Background Art

[0002] At present, the production line of felt (such as aerogel felt or PAN fiber felt) usually consists of pretreatment equipment, feeding equipment, needle punching equipment, heat setting equipment, trimming and winding equipment, etc. Among them, the needle punching equipment is the core part of the production line, including a pre-needle punching machine, a normal needle punching machine, a reverse needle punching machine, etc. The fibers are interwoven with each other to form a felt through the needle punching action.

[0003] However, during the needle punching process, broken needles are inevitable. Therefore, basically, on-line broken needle detection is required after needle punching. According to whether there is a broken needle (judged based on the magnetic adsorption method), once there is a broken needle, the felt in the corresponding detection area is adsorbed and relatively attached to the magnetic component, then the machine stops, and then the operator manually pulls out the broken needle.

[0004] Obviously, the above operation of removing broken needles still has the following difficulties:

[0005] 1) Since the felt is an interwoven product, once it is adsorbed and pulled, the formed interwoven gap will become smaller, increasing the difficulty of pulling out the broken needle;

[0006] 2) Magnetic adsorption is a whole-section adsorption. Since the broken needles are hidden in the felt and the lengths of the broken needles are different, it not only increases the difficulty of manual extraction, but also increases the probability of missed handling of broken needles, thus affecting the quality of the felt. At the same time, it is not conducive to subsequent cutting, sewing and other series of processing;

[0007] 3) With the requirement of the thickness of the felt itself, the general thickness is about 1.2 - 6.5 mm, and magnetic screening on one side has a high probability of missed detection. Summary of the Utility Model

[0008] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved double-station felt double-sided broken needle removing system.

[0009] To solve the above technical problem, the utility model adopts the following technical solutions:

[0010] A double-station felt cloth double-sided broken needle removal system, comprising a front broken needle removal device and a back broken needle removal device, and a cloth turning device, wherein the front broken needle removal device comprises a front magnetic detection unit and a first operating station, the felt cloth is transferred from the front side to the front detection area of the front magnetic detection unit from bottom to top, the first operating station comprises a first operating platform, a first ejector component formed at the feeding end of the front detection area, and a first magnetic suction component arranged corresponding to the first ejector component, the first ejector component extends along the width direction of the felt cloth, and contacts the front and / or back side of the felt cloth to put the felt cloth in a tensioned state to repeatedly and multiple times eject the broken needles out of the felt cloth, the first magnetic suction component is close to the end where the broken needle emerges, and absorbs the broken needle;

[0011] The back-side broken needle removal device comprises a back-side magnetic force detection unit identical to the front-side magnetic force detection unit, and a second operating station identical to the first operating station, wherein the back-side magnetic force detection unit is located below the discharge end of the second ejector component of the second operating station, and the felt cloth passes through the second operating station and the back-side magnetic force detection unit from top to bottom, the second ejector component extends along the width direction of the felt cloth, and contacts the front and / or back of the felt cloth to put the felt cloth in a tensioned state to repeatedly and multiple times eject the broken needle out of the felt cloth, and the second magnetic suction component is close to the end where the broken needle emerges, and absorbs the broken needle;

[0012] The cloth turning device is located between the front broken needle removing device and the back broken needle removing device, and is used for turning the felt cloth between the front and back sides so as to pass through the second ejector needle component.

[0013] Preferably, the first ejector pin component includes a plurality of ejector pin groups whose ejection contact force increases gradually from bottom to top, and each ejector pin group has at least three broken needle extrusion points; the first magnetic attraction component includes a magnetic attraction group corresponding to each ejector pin group. The three broken needle extrusion points form at least three extrusions to achieve repeated extrusion of the front and back sides (of course, the number of broken needle extrusion points can be four, five or more), which makes the pinhole larger and facilitates magnetic attraction (effectively removing broken needles).

[0014] According to a specific implementation and preferred aspect of the utility model, each ejector pin group includes a plurality of ejector pins that are relatively spaced in both the vertical direction and the felt cloth thickness direction, and an external connection seat for fixing the plurality of ejector pins relatively from the end, wherein the felt cloth passes through the plurality of ejector pins from bottom to top in the felt cloth thickness direction so that a V-shaped sharp angle ejection support is formed between every three of the ejector pins, and the felt cloth is ejected outward by the tip of the V-shaped sharp angle, and the magnetic adsorption group is correspondingly arranged at the tip of the V-shaped sharp angle. The extrusion with a V-shaped angle will not cause damage to the felt cloth due to broken needles, and is more conducive to the ejection operation.

[0015] In a specific embodiment, the V-shaped angle formed by the tips of each thimble group of the first thimble component has a gradually decreasing adsorption force from bottom to top; the angle formed by the tips of each of the thimble groups of the second thimble component has a gradually decreasing adsorption force from bottom to top. In this way, as the felt is transported, under the action of different extrusion forces, needles of different lengths can be effectively extruded, and it is easier first and then more difficult, reducing the probability of missed removal of broken needles.

[0016] Preferably, the cross-section of the ejector rod is circular or elliptical or triangular; in this application, there are three ejector rods, and the centers of the three ejector rods are distributed in an isosceles triangle in the orthographic projection in their own axial direction. Such a layout is more conducive to the fitting of the felt and is also conducive to the extrusion of broken needles.

[0017] According to another specific implementation and preferred aspect of the present invention, the magnetic adsorption group includes two mounting seats located on both sides and a magnetic rod mounted between the two mounting seats from the end, and the magnetic rod is correspondingly distributed with the tip. Adopting the layout of the magnetic rod corresponding to the tip is more conducive to the adsorption of broken needles.

[0018] According to another specific implementation and preferred aspect of the present invention, the adsorption force of each magnetic adsorption group of the first magnetic adsorption component increases gradually from bottom to top; the adsorption force of each magnetic adsorption group of the second magnetic adsorption component increases gradually from top to bottom. As the adsorption difficulty increases, a greater adsorption force is required.

[0019] According to another specific implementation and preferred aspect of the present invention, the distance from each magnetic adsorption group of the first magnetic adsorption component to the tip gradually decreases from bottom to top; the adsorption force of each magnetic adsorption group of the second magnetic adsorption component gradually decreases from top to bottom. Further, according to the layout of different spacing distances, the optimal adsorption force is further improved.

[0020] Preferably, each magnetic adsorption group of the first magnetic adsorption component is located on the same side of the felt and is located on the relatively outer side of the external seat. This is very convenient for the installation of the magnetic adsorption group.

[0021] In addition, the cloth turning device includes a turning seat located on the tops of the first operation platform and the second operation platform, multiple parallel turning rollers installed on the turning seat, and a turning motor for driving any one or more of the turning rollers to rotate. Among them, under the rotation transmission of the multiple turning rollers, the felt is transmitted from the back facing down and inward to the second thimble component, and keeps the back facing down and facing the back detection area. Generally, there are three turning rollers, which are distributed in a triangular shape, and only one of them needs to be driven, and the remaining two rotate idly.

[0022] As for the magnetic force detection unit (the front magnetic force detection unit and the back magnetic force detection unit have the same structure), it includes a fixed seat, a magnetic force transmission roller, and a magnetic sensor. The magnetic sensor performs magnetic force detection on the felt cloth after being processed at the operation station and can give an alarm. In short, the magnetic force detection unit is the last guarantee. As long as the detection is passed, the probability of broken needles in the felt cloth is basically zero. Moreover, once an alarm is given, it means that there are needles that have not been adsorbed and removed. At this time, only manual emergency treatment can be carried out.

[0023] Due to the implementation of the above technical solutions, the present utility model has the following advantages compared with the prior art:

[0024] Based on the existing operation of removing broken needles, since the felt cloth is an interwoven product, once adsorption causes pulling, the formed interwoven gaps will become smaller, increasing the difficulty of pulling out the broken needles. At the same time, magnetic adsorption is a whole-section adsorption. Since the broken needles are hidden in the felt cloth and the lengths of the broken needles are different, not only does it increase the difficulty of manual removal, but also increases the probability of missed treatment of broken needles, thereby affecting the quality of the felt cloth. At the same time, it is not conducive to subsequent processing such as cutting and sewing. In addition, with the requirements for the thickness of the felt cloth itself, the general thickness is about 1.2 - 6.5 mm, and there are many deficiencies such as a high probability of missed detection when performing magnetic screening on one side. However, the present application conducts an overall design on the double-station felt cloth double-sided broken needle removal system, skillfully solves the deficiencies and defects of the prior art. After adopting this double-station felt cloth double-sided broken needle removal system, based on the double stations and the cloth turning and transferring, first remove the broken needles with the front side facing in and the back side facing out, and then after passing through the cloth turning and transferring part, remove the broken needles with the front side facing out and the back side facing in. The process of removing the broken needles adopted is the same, and both use the method of repeatedly squeezing and ejecting on the front and back sides to extrude the broken needles out of the felt cloth to expand the needle hole gaps, and then use magnetic adsorption to remove the broken needles. Therefore, compared with the prior art, on the one hand, the present utility model adopts double stations to sequentially extrude the front and back sides of the felt cloth, and during the extrusion, it uses the method of repeatedly ejecting to expand the needle holes to relatively loosen the broken needles from the felt cloth, and then combines magnetic adsorption to remove the broken needles. That is, it not only meets the need to remove broken needles from felt cloth of different thicknesses, but also long and short broken needles can be effectively ejected, and at the same time, no manual labor is required and the efficiency is high. On the other hand, based on the removal detection of the front and back magnetic force detection units after removal, the quality of broken needle removal is further controlled to avoid economic losses caused by missed broken needles.

[0040] As Figures 1 to 5 shown, the double-station felt double-sided broken needle removing system of this embodiment includes a front broken needle removing device 1, a back broken needle removing device 2, and a cloth turning device 3.

[0041] Specifically, the front broken needle removing device 1 includes a front magnetic force detection unit 10 and a first operation station 11. The felt cloth M is transmitted from the bottom up towards the front detection area of the front magnetic force detection unit 10. The first operation station 11 includes a first operation platform 110, a first thimble component 111 formed at the feeding end of the front detection area, and a first magnetic attraction component 112 correspondingly arranged with the first thimble component 111. The first thimble component 111 extends along the width direction of the felt cloth M and abuts against the front and / or back of the felt cloth M to repeatedly and multiple times push the broken needle out of the felt cloth M under the tension state of the felt cloth M. The first magnetic attraction component 111 is close to the protruding end of the broken needle and adsorbs the broken needle.

[0042] In some specific embodiments, the first thimble component 111 includes multiple thimble groups a with gradually increasing top contact force formed from bottom to top, and each thimble group a has at least three broken needle extrusion points; the first magnetic attraction component 112 includes a magnetic force adsorption group b corresponding to each thimble group a. The three broken needle extrusion points at least form three extrusions in this way to achieve repeated extrusion on the front and back (of course, the number of broken needle extrusion points can be four, five or more), which makes the needle holes larger, and thus facilitates magnetic adsorption (effectively removing the broken needle).

[0043] In this example, each thimble group a includes multiple thimble rods a1 with relative intervals in the up-down direction and the thickness direction of the felt cloth M, and an external connection seat a2 for relatively fixing the multiple thimble rods a1 from the ends. The felt cloth M winds through the multiple thimble rods a1 in the thickness direction of the felt cloth M from bottom to top so that a V-shaped sharp angle is formed between every three thimble rods, and the felt cloth M is pushed out by the tip of the V-shaped sharp angle. The magnetic force adsorption group b is correspondingly arranged at the tip of the V-shaped sharp angle. Using the extrusion of the V-shaped angle will not cause damage to the felt cloth by the broken needle, and is more conducive to the ejection operation. The cross-section of the thimble rod a1 is circular or oval or triangular; in this application, there are three thimble rods a1, and the centers of the three thimble rods are distributed in an isosceles triangle in the orthographic projection of their own axial directions. Such a layout is more conducive to the fitting of the felt cloth and is also conducive to the extrusion of the broken needle. The magnetic force adsorption group b includes two mounting seats b1 on both sides and a magnetic rod b2 mounted between the two mounting seats b1 from the ends, and the magnetic rod b2 is correspondingly distributed with the tip. Using the layout of the magnetic rod corresponding to the tip is more conducive to the adsorption of the broken needle. Each magnetic force adsorption group b of the first magnetic attraction component 112 is located on the same side of the felt cloth M and is located on the relative outer side of the external connection seat a2. This is very convenient for the installation of the magnetic force adsorption group.

[0044] The back-side broken needle removal device 2 includes a back-side magnetic detection unit 20 that is the same as the front-side magnetic detection unit 10, and a second operating station 21 that is the same as the first operating station 11, wherein the back-side magnetic detection unit 20 is located below the discharge end of the second ejector component 211 of the second operating station 21, and the felt cloth M passes through the second operating station 21 and the back-side magnetic detection unit 20 from top to bottom, the second ejector component 211 extends along the width direction of the felt cloth M, and contacts the front and / or back side of the felt cloth M to put the felt cloth M in a tensioned state to repeatedly and multiple times eject the broken needle out of the felt cloth M, and the second magnetic suction component 212 is close to the end where the broken needle emerges, and absorbs the broken needle.

[0045] Although the back broken needle removal device 2 and the front broken needle removal device 1 have the same structure, there are still the following differences in layout: 1) The V-shaped angle formed by the tips of each ejector group a of the first ejector component 111 has a gradually smaller adsorption force from bottom to top; the angle formed by the tips of each ejector group of the second ejector component 211 has a gradually smaller adsorption force from bottom to top. In this way, with the transmission of the felt cloth, under the action of different extrusion forces, broken needles of different lengths can be effectively extruded, and the easy ones are removed first and then the difficult ones, reducing the probability of missing broken needles.

[0046] 2) The adsorption force of each magnetic adsorption group of the first magnetic attraction component 111 increases gradually from bottom to top; the adsorption force of each magnetic adsorption group of the second magnetic attraction component 211 increases gradually from top to bottom. As the adsorption difficulty increases, the required adsorption force is greater.

[0047] 3) The distance from each magnetic attraction group of the first magnetic attraction component 111 to the tip gradually decreases from bottom to top; the attraction force of each magnetic attraction group of the second magnetic attraction component 211 gradually decreases from top to bottom. Further, according to the layout of different spacing distances, the optimal attraction force is further improved.

[0048] As for the magnetic detection unit (the front magnetic detection unit 10 or the back magnetic detection unit 20 has the same structure), it includes a fixed seat g1, a magnetic transmission roller g2, and a magnetic sensor g3, wherein the magnetic sensor g3 performs magnetic detection on the felt cloth processed by the operating station and can give an alarm. In short, the magnetic detection unit is the last guarantee. As long as it is detected, the probability of broken needles in the felt cloth is basically zero; and once an alarm is given, it means that it has not been adsorbed and removed. At this time, emergency treatment can only be carried out manually.

[0049] In addition, the cloth turning device 3 is located between the front broken needle removing device 1 and the back broken needle removing device 2, and is used for turning the felt cloth M between the front and back sides through the second ejector component 211.

[0050] Specifically, the cloth turning device 3 includes a turning base 30 located on the tops of the first operation platform 110 and the second operation platform 210, multiple parallel turning rollers 31 installed on the turning base 30, and a turning motor 32 for driving any one or more of the turning rollers 31 to rotate. Under the rotation transmission of the multiple turning rollers 31, the felt cloth M is transmitted from the state with the back side facing downwards and inwards to the second thimble member 211, and is transmitted downwards while keeping the back side facing the back detection area. Generally, there are three turning rollers, which are distributed in a triangular pattern, and only one of them needs to be driven, and the remaining two rotate idly.

[0051] In summary, after adopting this double-station felt cloth double-sided broken needle removal system, based on the double stations and cloth turning transfer, the broken needles are first removed with the front side facing inwards and the back side facing outwards, and then after passing through the cloth turning transfer part, the broken needles are removed with the front side facing outwards and the back side facing inwards. The process of removing the broken needles adopted is the same, and the broken needles are extruded out of the felt cloth by repeatedly squeezing and ejecting on both the front and back sides to expand the needle hole gap, and then the broken needles are removed by magnetic adsorption. Therefore, compared with the prior art, on the one hand, the present utility model adopts double stations to sequentially extrude the front and back sides of the felt cloth, and in the extrusion, the broken needles are relatively loosened from the felt cloth by repeatedly ejecting to expand the needle holes, and then combined with magnetic adsorption to remove the broken needles. That is, it not only meets the need of removing broken needles from felt cloths of different thicknesses, but also long and short broken needles can be effectively ejected, and at the same time, no manual labor is required and the efficiency is high; on the other hand, based on the removal detection of the front and back magnetic detection units after removal, the quality of broken needle removal is further controlled to avoid economic losses caused by missed broken needles; on the third hand, at least three extrusions are formed at the three broken needle extrusion points to achieve repeated extrusion on the front and back sides (of course, the number of broken needle extrusion points can be four, five or more), so that the needle holes become larger, which is convenient for magnetic adsorption (effectively implementing broken needle removal); on the fourth hand, the extrusion with a V-shaped angle will not cause damage to the felt cloth by the broken needles, and is more conducive to the ejection operation. At the same time, with the transmission of the felt cloth, under the action of different extrusion forces, broken needles of different lengths can be effectively extruded, and it is easier first and then more difficult, reducing the probability of missed removal of broken needles; on the fifth hand, the layout of the magnetic rods corresponding to the tips is more conducive to the adsorption of broken needles. At the same time, as the adsorption difficulty increases, a greater adsorption force is required. In addition, according to the layout of different spacing distances, the best adsorption force is further improved.

[0052] The above has made a detailed description of the present utility model, aiming to enable those skilled in this field to understand the content of the present utility model and implement it. However, the protection scope of the present utility model cannot be limited thereby. Any equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
