Description

[Technical Field]

[0001] This utility model relates to the field of rubber wave structure technology, and in particular to a rubber wave opening and positioning mechanism for denim processing. [Background Technology]

[0002] Currently, one step in the processing of jeans involves decolorizing or machine rubbing with potassium permanganate. Because potassium permanganate is highly corrosive, this is typically done using a robotic arm. When jeans are inflated and tightened, the legs need to be kept full to facilitate spraying the surface. This inflating fixture is called a rubber band. Since the positioning in robotic operations is precise, misalignment or displacement during inflating or turning the jeans can occur, leading to inconsistent angles and incorrect spraying positions by the robotic arm. Traditional denim rubber bands have a straight-tube structure. One end is tied and sealed with a rope, while the other end is connected and tied to the air injection tube. This straight-tube design makes it impossible for the inflated legs to achieve a consistent angle, resulting in deviations in the position and angle when spraying potassium permanganate onto the jeans.

[0003] In view of the above-mentioned technical problems, this utility model proposes a rubber wave opening and positioning mechanism for denim processing. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to provide a rubber wave opening and positioning mechanism for denim processing, so as to solve the technical problem in the prior art that two support skeletons are arranged opposite each other on both sides of axis A as the center, and two opening and positioning components are used to adjust the two support skeletons to a predetermined angle and keep them consistent, so as to prevent misalignment during spraying.

[0005] To solve the above-mentioned technical problems, the present invention includes a rubber wave opening and positioning mechanism for denim processing, including a connecting seat, two support frames are provided at intervals at the bottom of the connecting seat, and two opening and positioning components are provided below the connecting seat. Each opening and positioning component positions the lower end of the two support frames accordingly, and the two support frames are symmetrically arranged about axis A, and the two opening and positioning components are symmetrically arranged about axis A.

[0006] Furthermore, the support frame includes a rigid connecting pipe and an angle support rod. One end of the rigid connecting pipe is rigidly connected to the connecting seat, and the rigid connecting pipe is provided with an air hole for inflation and deflation of the rubber wave. The air hole can communicate with the air pipe on the connecting seat. The upper end of the angle support rod is hinged to the lower end of the rigid connecting pipe, and the lower ends of the two angle support rods can respectively abut against the opening positioning component so that the two angle support rods are kept open to a predetermined angle.

[0007] Furthermore, the upper end of the angle support rod is connected to the lower end of the rigid connecting pipe through a ball joint.

[0008] Furthermore, the lower end of the angle support rod is provided with a guide portion that can slide or roll against the opening positioning component.

[0009] Furthermore, the corrugated board opening and positioning mechanism also includes a connecting beam for connecting to the ground. The two opening and positioning components are connected to the connecting beam about axis A. The opening and positioning components include a lifting drive and a positioning guide. The lifting drive is connected to the connecting beam. The bottom of the positioning guide is connected to the output end of the lifting drive so that when the positioning guide is raised, it abuts against the lower end of the support frame, and the lower end of the support frame produces a predetermined sway angle relative to axis A.

[0010] Furthermore, the positioning guide includes a downwardly inclined guide block, the upper edge of which is connected to form a closed guide opening, and the lower part of the guide block has a positioning part. The cross-section of the positioning guide gradually narrows from the guide opening to the positioning part, making the positioning guide as a whole have a trumpet-shaped structure.

[0011] Furthermore, the positioning guide has a conical or pyramidal structure.

[0012] Furthermore, the connecting beam is also provided with a spacing adjustment component for adjusting the distance between the two opening positioning components. The spacing adjustment component includes an adjustment seat connected to the bottom end of the lifting drive component and a clamp component that is movably sleeved on the connecting beam. The adjustment seat is connected to the clamp component by bolts.

[0013] Furthermore, the adjusting seat is provided with a height adjusting component that cooperates with the clamp to adjust the vertical height of the adjusting seat. The height adjusting component includes several adjusting bolts that are threadedly engaged with the adjusting seat, and several fixing bolts that pass through the adjusting seat and are fixedly connected to the clamp at the bottom. It also includes a fixing nut that is threadedly engaged with the fixing bolt. The bottom of the adjusting bolt abuts against the top of the clamp, and the fixing nut is located above the adjusting seat. The adjusting seat is provided with a strip hole for the fixing bolt to pass through.

[0014] Furthermore, the angle between the guide blocks on the opposing sides of the two positioning guides and the horizontal plane is α, and the angle between the guide blocks on the opposing sides of the two positioning guides and the horizontal plane is β, and β>α is satisfied.

[0015] Compared with the prior art, the rubber wave spreading and positioning mechanism for denim processing of this utility model has the following advantages:

[0016] 1. This application uses two opening positioning components to fix the jeans to the lower end of the corresponding support frame. During the spraying process, the two support frames can support the jeans smoothly and symmetrically along axis A, so that when spraying potassium permanganate, it can be sprayed more evenly on the jeans, preventing the jeans from shifting and causing spraying deviation.

[0017] 2. In this application, by setting an opening positioning component on the spacing adjustment component and the height adjustment component under the opening angle support rod, after initial adjustment, the two opening angle support rods slide to the positioning part along the guide member on the α side of the opening positioning component. The guide member on the β side has a larger included angle than the guide member on the α side, so the guide member on the β side plays a limiting role, ultimately limiting the opening angle of the two opening angle support rods to be consistent. When used for products of the same series, the opening angle of the opening angle support rods is made consistent through the adjustment of the spacing adjustment component, the height adjustment component, and the opening positioning component, reducing the time required for repositioning due to angle deviation and effectively improving productivity. When used in different series, the adjustment component and the opening positioning component can adjust the opening angle support rods to different angles, making it more widely applicable.

Detailed Implementation Methods

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 1-10 As shown, this utility model includes a rubber wave opening and positioning mechanism for denim processing, comprising a connecting seat 2, with two support frames 1 spaced apart at the bottom of the connecting seat 2, and two opening and positioning components 3 disposed below the connecting seat 2. Each opening and positioning component 3 positions the lower end of the two support frames 1 accordingly. The rubber wave opening and positioning mechanism also includes a connecting beam 4 for connecting to the ground, with the two opening and positioning components 3 connected to the connecting beam 4. The two support frames 1 and the two opening and positioning components 3 are symmetrically arranged about axis A. During the denim spraying operation, rubber waves 8 are placed outside the support frames 1 to support the denim and prevent it from slipping.

[0035] This application uses two opening positioning components 3 to position and fix the jeans at the lower end of the corresponding support frame 1. During the spraying process, the two support frames 1 can stably and symmetrically support the jeans along axis A, so that when spraying potassium permanganate, it can be sprayed more evenly on the jeans, preventing the jeans from shifting and causing spraying deviation.

[0036] In this utility model, the support frame 1 includes a rigid connecting pipe 11 and a flared support rod 12. One end of the rigid connecting pipe 11 is fixedly connected to the connecting seat 2. After the jeans are put on, the air pipe on the connecting seat 2 is connected through the air hole 111 on the rigid connecting pipe 111 to inflate and deflate the rubber wave 8. Subsequently, the upper end of the flared support rod 12 is hinged to the lower end of the rigid connecting pipe 11 by a pin connection. The upper end of the flared support rod 12 and the lower end of the rigid connecting pipe 11 can also be connected by a ball joint. The lower ends of the two flared support rods 12 can respectively abut against the opening positioning component 3. The lower end of the flared support rod 12 is provided with a guide part 121 that can slide or roll against the opening positioning component 3. When the external cylinder works, gas is transported along the connecting seat 2 and output from the air hole 111, inflating and tightening the rubber wave 8. Then, the guide part 121 in the angle support rod 12 slides or rolls along the opening positioning assembly 3 with axis A as the center, and remains in an inflated and tightened state.

[0037] like Figures 2 to 6 As shown, as a further embodiment, since the leg opening angles of different models of jeans are inconsistent, a spacing adjustment component 5 is also provided on the connecting beam 4 to adjust the distance between the two opening positioning components 3 in order to further adapt to different models of jeans. The spacing adjustment component 5 includes an adjustment seat 51 connected to the bottom end of the lifting drive component 31 and a clamp 52 movably fitted onto the connecting beam 4. The adjustment seat 51 is connected to the clamp 52 by bolts. The clamp 52 consists of a U-shaped retaining ring 520 and a connecting plate 521 disposed on the U-shaped retaining ring 520. The U-shaped retaining ring 520 and the connecting plate 521 are connected by bolts, thereby fixing them to the connecting beam 4. The adjustment seat 51 is then fixed to the connecting plate 521 by bolts. By loosening the bolts between the U-shaped retaining ring 520 and the connecting plate 521, the distance between the two opening positioning components 3 can be adjusted. After adjusting to a preset value, the adjustment seat 51 is then fixed to adapt to different models of jeans.

[0038] like Figures 2 to 6As shown, as a further embodiment, the adjusting seat 51 is provided with a height adjusting component 6 that cooperates with the clamp 52 to adjust the vertical height of the adjusting seat 51. The height adjusting component 6 includes several adjusting bolts 60 that are threadedly engaged with the adjusting seat 51, and several fixing bolts 61 that pass through the adjusting seat 51 and are fixedly connected to the clamp 52 at the bottom. It also includes fixing nuts 62 that are threadedly engaged with the fixing bolts 61. The bottom of the adjusting bolts 60 abuts against the top of the clamp 52, and the fixing nuts 62 are located above the adjusting seat 51. The adjusting seat 51 is provided with a strip-shaped hole for the fixing bolts 61 to pass through. When initially installing the entire rubber wave opening and positioning mechanism, it is necessary to adjust the height of the opening and positioning component 3, or it may be necessary to adjust the height of the opening and positioning component 3 during later maintenance and adjustment. Therefore, by setting the height adjusting component 6, it is convenient to adjust the height of the opening and positioning component 3.

[0039] In this embodiment, the fixing bolt 61 is fixedly connected to the connecting plate 521 in the clamp 52, and the bottom of the corresponding adjusting bolt 60 abuts against the connecting plate 521. When adjusting the height adjustment component 6, rotating the adjusting bolt 60 will lift the adjusting seat 51. After the adjusting seat 51 is lifted to the correct position, rotating the fixing nut 62 will press the adjusting seat 51 downward, thereby fixing the adjusting seat 51 and adjusting the height of the opening positioning component 3. Alternatively, the levelness of the opening positioning component 3 can also be adjusted by the cooperation of the adjusting bolt 60, the fixing bolt 61, and the fixing nut 62.

[0040] Furthermore, since the adjusting seat 51 has a strip-shaped hole, the horizontal position of the adjusting seat 51 can be finely adjusted. With the help of the clamp 52, the horizontal position of the opening positioning component 3 can be adjusted.

[0041] like Figures 8 to 10 As shown, the opening positioning component 3 includes a lifting drive component 31 and a positioning guide component 32. The positioning guide component 32 includes a downwardly inclined guide block 321. The upper edge of the guide block 321 forms a closed guide opening 322. The lower part of the guide block 321 has a positioning part 333. The cross-section of the positioning guide component 32 gradually narrows from the guide opening 322 to the positioning part 333, making the positioning guide component 32 have an overall trumpet-shaped structure. In this application, the lifting drive component 31 is a cylinder. The positioning part 333 in the trumpet-shaped guide component 32 is connected to the piston rod of the cylinder. The lifting drive component 31 is connected to the connecting beam 4. The bottom of the positioning guide component 32 is connected to the output end of the lifting drive component 31 so that when the positioning guide component 32 is raised, it abuts against the lower end of the support frame 1, and the lower end of the support frame 1 moves relative to the axis A to the position of the positioning part 333 for fixing.

[0042] The guide part 121 can also be spherical, rolling along the guide block 321 in the positioning guide 32, so that the angle support rod 12 moves more smoothly and steadily. The positioning guide 32 can also be a conical or pyramidal structure. In this example, the positioning guide 32 adopts a trumpet-shaped structure. The angle between the guide block 321 on the facing side of the two positioning guides 32 and the horizontal plane is α, and the angle between the guide block 321 on the opposite side of the two positioning guides and the horizontal plane is β. The angle of β is greater than the angle of α. Therefore, in the inflation state, with axis A as the center, the cylinders in the two lifting drive parts 31 work to make the two positioning guides 32 rise. The guide part 121 in the two support frames 1 slides along the guide block 321 on the α side of the two angle support rods 12 to the positioning part 333, keeping the opening angle of the two angle support rods 12 consistent and tensioned so that the position is consistent during spraying.

[0043] It should be noted that the lifting drive component 31 can be a multi-axis cylinder, which can be directly or indirectly mounted on the adjusting seat 51, and the positioning guide component 32 is mounted on the end of the output shaft of the multi-axis cylinder. Alternatively, the lifting drive component 31 can be a conventional cylinder, with a mounting base on the adjusting seat 51 for fixing the conventional cylinder. The positioning guide component 32 is connected to the output shaft of the conventional cylinder, and a guide rod is mounted on the positioning guide component 32 that slides with the mounting base for guiding and limiting.
