[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1 to 9The utility model discloses a kind of aviation tire corrugated crown belt protective layer production equipment 1 (hereinafter referred to as corrugated crown belt protective layer production equipment), including spindle rack 10, the spindle rack 10 is used to provide a certain number of fiber components 100 (the fiber component 100 includes nylon and / or aramid etc. Non-steel wire fiber);Tension control device 20, the tension control device 20 is used to control the pay-off tension of fiber component 100 on spindle rack 10;Corrugated forming wire arranging device 30, the corrugated forming wire arranging device 30 is provided with the silk outlet component 31 that can reciprocate along first direction (such as X axis direction), a plurality of silk outlet holes 311 are arranged at certain distance interval on the silk outlet component 31, and the fiber 100 component is sequentially arranged through silk outlet hole 311;Compound forming device 40 is oppositely arranged with corrugated forming wire arranging device 30, and the compound forming device 40 has a pair of counter-rotating compound roller groups 41, i.e. two counter-rotating compound rollers driven by driving source (not shown);It also includes film supply device, the film supply device includes first film supply device 51 arranged above compound forming device 40 and second film supply device 52 arranged below compound forming device 40, the first film supply device 51 is used to provide first film 200 for compound forming device 40, and the second film supply device 52 is used to provide second film 300 for compound forming device 40, and the first film 200, sequentially arranged fiber component 100 and second film 300 are pressed and combined to form corrugated crown belt protective layer by counter-rotating of compound roller groups 41.

[0026] The corrugated crown belt protective layer production equipment disclosed in the utility model is through the real-time reciprocating movement of silk outlet component 31 along first direction, so that a plurality of fiber components 100 passing through compound roller groups 41 present corrugated shape as shown Figure 10 The first film 200 and the second film 300 are adhered to each other to press and combine fiber component 100 between the first film 200 and the second film 300. When the film (the film refers to the first film 200 and the second film 300) reaches compound roller groups 41 by film supply device, it is usually in normal temperature state rather than hot glue state, and the corrugated crown belt protective layer formed by pressing and combining the film in normal temperature state is easy to delaminate, and the pressing and combining quality is not very good. Therefore, in order to solve the above technical problems, the compound roller groups 41 of the utility model are two heating rollers with a certain temperature, the heating rollers are heated by electromagnetic, water and other ways, so that the surface of the heating rollers has a certain temperature. When the first film 200 and the second film 300 contact with the two heating rollers, the adhesion of the first film 200 and the second film 300 can be increased, so as to be beneficial to improve the adhesion between the first film 200, the second film 300 and fiber component 100, and improve the pressing and combining quality of the corrugated crown belt protective layer.

[0027] As Figure 5The corrugated forming row of wire device 30 includes a wire arranging frame 32, a wire arranging mechanism 33 which can move along a first direction (such as the X-axis direction), and a wire arranging driving source 34 which is fixedly arranged on the wire arranging frame 32, the driving end of the wire arranging driving source 34 is connected with the wire arranging mechanism 33, and the wire arranging driving source 34 is used for driving the wire arranging mechanism 33 to reciprocate along the first direction; the wire arranging mechanism 33 is arranged on one end of the wire arranging frame 32 close to the composite forming device 40. When the composite roller group 41 rotates to drive a plurality of fiber components 100 to be conveyed along a second direction (such as the Y-axis direction), the wire arranging driving source 34 drives the wire arranging mechanism 33 to reciprocate along the first direction, and the fiber components 100 arranged in the wire hole 311 also reciprocate along the first direction, so that the fiber components 100 pressed between the first rubber sheet 200 and the second rubber sheet 300 are in a continuous wave shape.

[0028] In the process that the fiber components 100 enter the composite roller group 41 from the wire hole 311, if the wire hole 311 is far away from the composite roller group 41, the fiber components 100 can be easily displaced without constraint, thereby affecting the corrugated shape of the corrugated crown protection layer. Therefore, in order to ensure the corrugated shape of the corrugated crown protection layer, the wire hole 311 needs to be as close to the composite roller group 41 as possible. Preferably, the wire arranging frame 32 is provided with a sliding plate 35 which can move along the second direction, the wire arranging mechanism 33 is movably arranged on the sliding plate 35, and a telescopic driving source 36 is fixedly arranged on the wire arranging frame 32, the driving end of the telescopic driving source 36 is connected with the sliding plate 35, and the telescopic driving source 36 is used for driving the sliding plate 35 to move along the second direction, so that the wire arranging mechanism 33 is driven to be close to the composite roller group 41, and the wire arranging mechanism 31 can be placed at a gap position between the two composite rollers or away from the composite roller group.

[0029] Preferably, the wire arranging mechanism 33 further includes a wire entering part 37, a plurality of wire entering holes 371 are arranged on the wire entering part 37 opposite to the wire hole 311, the interval of the plurality of wire entering holes 371 is consistent with the interval of the plurality of wire holes 311, and the arrangement height of the wire entering hole 371 is consistent with the arrangement height of the wire hole 311, so that the fiber components 100 are pressed after passing through the wire entering hole 371 and then passing through the wire hole 311, and the consistency between the plurality of fiber components 100 is better.

[0030] As Figure 1 and 3The first film supply device 51 includes a first film guide opening device 511 and a first film conveying device 512, and the second film supply device 52 includes a second film guide opening device 521. Since the first film 200 and the second film 300 are guided and conveyed by the film supply device to a position between the laminating roller set 41 and the laminating roller set 41, the position of the first film 200 and the second film 300 on the laminating roller set is not fixed, and the range may exceed the production requirements. Therefore, the film deviation correcting device is further arranged on the laminating forming device 40, so that the conveying position of the first film 200 and the second film 300 is adjusted in real time, so that the position of the first film 200 and the second film 300 on the laminating roller set is satisfied.

[0031] As shown in Figure 4 and 8 Specifically, the laminating forming device 40 includes a support frame 42, and the laminating roller set 41 is arranged on the support frame 42 and is driven to rotate by an independent driving source (not shown). The film deviation correcting device includes a first film deviation correcting device 60A arranged above the laminating roller set 41 and a second film deviation correcting device 60B arranged below the laminating roller set 41.

The film deviation correcting device 60 further includes a pair of detection units 615 arranged between the deviation roller 613 and the laminating roller set 41, and the pair of detection units 615 have a conveying space (not shown) for the fiber component 100 to pass through. In use, the first film 200 and the second film 300 pass through the conveying space of the detection unit from the respective film supply device to the deviation roller 613 and then to the laminating roller set 41. The detection unit 615 has a detection interval (not shown), and after the fiber component 100 passes through the detection interval and is detected, according to the parameters of the detection interval, the deviation driving source drives the deviation roller 613 to move on the fixed shaft 612, so as to adjust the position of the fiber component 100 in the conveying space of the detection unit and correct in real time.

[0032] As shown in Figure 7 and 8As shown, further, the film deviation correction device further comprises a material picking mechanism 616, which is arranged between the film feeding device and the deviation correction roller 613, and the material picking mechanism 616 comprises a material picking driving source 6161 and a material picking roller 6162, the material picking driving source 6161 is fixedly arranged on the deviation correction mounting frame 611, and the driving end of the material picking driving source 6161 is fixedly connected with the material picking roller 6162. When the fiber component 100 exceeds the detection interval of the detection unit, the material picking driving source 6161 drives the material picking roller 6162 to extend out, so that the fiber component 100 is no longer in contact with the deviation correction roller 613, and the deviation correction driving source drives the deviation correction roller 613 to reset, and then the fiber component 100 is re-corrected.

[0033] As shown in Figure 4 and 9 In order to avoid bubbles generated after the first film 200, the fiber component 100 and the second film 300 are pressed, so that the corrugated crown tape protective layer is delaminated, the corrugated crown tape protective layer production equipment further comprises a film piercing roller device 53, which is arranged between the film feeding device and the composite forming device 40, and the film piercing roller device 53 comprises a first film piercing roller device 53A arranged between the first film feeding device 51 and the composite forming device 40, and the first film piercing roller device 53A is used for piercing the first film 200, and a second film piercing roller device 53B arranged between the second film feeding device 52 and the composite forming device 40, and the second film piercing roller device 53B is used for piercing the second film 300. The first film piercing roller device 53A and the second film piercing roller device 53B have the same structure, specifically, the film piercing roller device 53 comprises a rotatable conveying roller 531, a plurality of piercing grooves 5311 are arranged on the conveying roller 531, a piercing roller driving source 532 and a piercing roller 533, the driving end of the piercing roller driving source 532 is connected with the piercing roller 533, and the piercing roller driving source 532 is used for driving the piercing roller 533 to approach or move away from the conveying roller 531, a needle piercing part 5331 is arranged on the piercing roller 533, and the needle piercing part 5331 is arranged in the piercing groove 5311 during use, the film is arranged between the piercing roller 533 and the conveying roller 531 after passing through the film conveying device, the piercing roller 533 and the conveying roller 531 are driven to rotate passively during conveying of the film to the next process, so that the needle piercing part 5331 on the piercing roller 533 pierces the film, and the first film 200 and the second film 300 have piercing holes, and the bubbles are discharged from the piercing holes of the film during pressing of the first film 200, the fiber component 100 and the second film 300.

[0034] As shown in Figure 1 and 3As shown, the corrugated crown belt protective layer production equipment further comprises a cutting device 71 and a curling device 72. The continuous corrugated crown belt protective layer formed by the compression molding device 40 is curled into a roll by the curling device 72, and then cut to a fixed length by the cutting device 71 after curling is completed. When producing corrugated crown belt protective layers of different specifications, the number of fiber components 100 between the first rubber sheet 200 and the second rubber sheet 300 is different, and the corrugated shape is also different. The distance and the reciprocating speed of the reciprocating movement of the fiber arrangement driving source 34 driving the fiber arrangement mechanism 33 can be adjusted to adjust the single corrugated shape, and the number and the spacing of the fiber outlet holes 311 can be adjusted to form different specifications.

[0035] As shown, Figure 4 It should be noted that, in the process of compression molding of the corrugated crown belt protective layer, in order to avoid the fiber components 100 from being placed on the side edges of the first rubber sheet 200 or the second rubber sheet 300 or outside the side edges, the width of the first rubber sheet 200 and the width of the second rubber sheet 300 are generally wider than the width of the corrugated crown belt protective layer. Therefore, the corrugated crown belt protective layer needs to be cut to a fixed width after compression molding is completed. Therefore, the corrugated crown belt protective layer production equipment further comprises an edge cutting device 81 for cutting the corrugated crown belt protective layer to a fixed width after compression molding is completed, and an edge material curling device 82 for curling and recycling the edge material after cutting. Preferably, the edge cutting device 81 and the edge material curling device 82 are arranged on the compression molding device 40 away from one end of the compression roller set 41.

[0036] As shown, Figure 3 When the compression roller set 41 is a heating roller, the corrugated crown belt protective layer after compression molding by the compression roller set 41 also has a certain temperature, and the corrugated crown belt protective layer curled by the curling device 72 cannot have a temperature. If the corrugated crown belt protective layer after compression molding by the compression roller set 41 cannot be completely cooled before the curling device 72, curling cannot be performed. Therefore, in order to ensure that the corrugated crown belt protective layer curled by the curling device 72 has been sufficiently cooled, the corrugated crown belt protective layer production equipment can further comprise a cooling drum device 90 arranged between the compression molding device 40 and the curling device 72 for cooling the corrugated crown belt protective layer after compression molding.

[0037] The number of fiber components 100 in the corrugated crown belt protective layer generally ranges from several tens to several hundred, and the fiber components 100 need to be combed and arranged between the spindle holder 10 and the fiber outlet hole 311, and cannot be mixed together. As shown, Figure 2Therefore, when the number of fiber components 100 is large, the spool holder 10 can be arranged in two groups, respectively arranged on both sides of the corrugated forming wire arranging device 30, each group including at least one spool holder 10, and the spool holder 10 and the corrugated forming wire arranging device 30 are arranged at an angle (i.e. the spool holder 10 and the corrugated forming wire arranging device 30 are not arranged in parallel), so that the fiber components 100 far away from the corrugated forming wire arranging device 30 in the first direction will not change too much in the conveying angle during the conveying to the corrugated forming wire arranging device 30, so that the consistency of the fiber components 100 is better.

[0038] The utility model mainly provides a kind of aviation tire corrugated crown belt protective layer production equipment, and fiber component is formed wave type by forming wire arranging device, and first rubber sheet, fiber component, second rubber sheet are pressed and formed corrugated crown belt protective layer by composite roller group, simple structure, convenient to use.
