Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0028] According to an embodiment of the present utility model, a cloth wrapping machine is provided. Please refer to Figures 1 to 6 , including: a support mechanism 1 for supporting a workpiece to be wrapped 10, and the workpiece to be wrapped 10 is rotatably connected to the support mechanism 1; a curtain cloth conveying mechanism for conveying the curtain cloth 20 to the inner circle 101 of the workpiece to be wrapped 10 so that the curtain cloth 20 fits the inner circle 101; a cloth wrapping mechanism 3 including a cloth wrapping roller 31 rotatably arranged to roll the curtain cloth 20 onto the inner circle 101 and bend the two sides of the curtain cloth 20 towards the side surface of the workpiece to be wrapped 10; a pressing mechanism 4 including a pressing roller 41 in contact with the side surface of the workpiece to be wrapped 10, and the pressing roller 41 presses the two sides of the curtain cloth 20 bent towards the side surface of the workpiece to be wrapped 10 against the workpiece to be wrapped 10.

[0029] With the above settings, the support mechanism 1 supports the workpiece to be wrapped 10, the curtain cloth conveying mechanism conveys the curtain cloth 20 so that the curtain cloth 20 reaches and fits the inner circle 101. As the workpiece to be wrapped 10 rotates, the curtain cloth 20 is pulled. At the same time, the cloth wrapping roller 31 rolls the curtain cloth 20 onto the entire inner circle 101 and bends the two sides of the curtain cloth 20 towards the side surface of the workpiece to be wrapped 10. The pressing roller 41 presses the side surfaces of the curtain cloth 20 bent towards the side surface of the workpiece to be wrapped 10 against the workpiece to be wrapped 10, making the curtain cloth 20 fit more tightly, thus completing the cloth wrapping process of a single workpiece to be wrapped 10. Applying the cloth wrapping machine in this embodiment to the tire production process, the machine replaces manual labor to complete the cloth wrapping of the bead wire, greatly reducing the labor intensity of the staff, making the curtain cloth distribution more uniform, the pressing more tight, improving the tire product quality, and solving the technical problems in the related tire production process that manual intervention is required during the cloth wrapping process, which is likely to cause asymmetry in cloth wrapping on the left and right, large tolerances, and unstable product quality.

[0030] Applying the cloth wrapping machine in this embodiment to the tire production process, the workpiece to be wrapped 10 is a bead wire wrapped with apex rubber. The cloth wrapping machine in this embodiment can automatically complete the process of fitting the curtain cloth on the outer side where the bead wire is connected to the apex rubber.

[0031] There are multiple support mechanisms 1, and the multiple support mechanisms 1 are concentrically arranged around the axis of the item to be wrapped 10. The support mechanism 1 drives the positioning and reciprocating movement of the guide wheel through a cylinder and a slider rail structure. After the item to be wrapped 10 is loaded, the support mechanisms 1 synchronously tighten outward along the radial direction, so that the guide wheels tightly press the item to be wrapped 10, and friction is formed between the item to be wrapped 10 and the wrapping cloth roller 31, so that the rotation of the wrapping cloth roller 31 drives the item to be wrapped 10 to rotate.

[0032] In the wrapping machine of this embodiment, refer to Figures 3 - 4 , the pressing roller 41 includes a first pressing roller 411 and a second pressing roller 412 arranged oppositely. The first pressing roller 411 and the second pressing roller 412 are both rotatably arranged, and a pressing space 413 for accommodating the item to be wrapped 10 is formed between the first pressing roller 411 and the second pressing roller 412. Specifically, through the relatively arranged first pressing roller 411 and second pressing roller 412, as the item to be wrapped 10 rotates continuously, the parts of the item to be wrapped 10 passing through the pressing space 413 are respectively rolled by the first pressing roller 411 and the second pressing roller 412, and at the same time, the cord fabrics on the two sides of the item to be wrapped 10 are adhered.

[0033] Specifically, the shapes of the contact surfaces of the first pressing roller 411 and the second pressing roller 412 with the item to be wrapped 10 are both matched with the side surface of the item to be wrapped 10, so that the cord fabric is pressed more tightly and evenly.

[0034] In the wrapping machine of this embodiment, refer to Figure 4 , the pressing mechanism 4 includes a floating shaft 42. The extending direction of the floating shaft 42 is perpendicular to the rotation axis of the first pressing roller 411. The first pressing roller 411 is rotatably arranged around the floating shaft 42 so that the first pressing roller 411 rotates relative to the second pressing roller 412. Specifically, the first pressing roller 411 is a floating pressing roller, which facilitates the loading and unloading of the item to be wrapped 10.

[0035] Specifically, the pressing mechanism 4 includes a driving cylinder and a connecting rod structure drivingly connected to the driving cylinder. The connecting rod structure is drivingly connected to the floating shaft 42. By extending or retracting the piston rod of the driving cylinder, the connecting rod structure can be driven to act, so that the floating shaft 42 rotates, so as to drive the first pressing roller 411 to rotate relative to the second pressing roller 412.

[0036] In the wrapping machine of this embodiment, refer to Figure 2, the cord fabric conveying mechanism includes: a cord fabric unwinding mechanism 21, the cord fabric unwinding mechanism 21 includes a storage roller 211 for storing the cord fabric 20 and the backing fabric 30 and a backing fabric take-up roller 212 for recycling the backing fabric 30, the cord fabric unwinding mechanism 21 includes a first driving component 213 drivingly connected to the storage roller 211 and the backing fabric take-up roller 212, the cord fabric unwinding mechanism 21 includes a peeling roller 214, after passing through the peeling roller 214, the cord fabric 20 is peeled off from the backing fabric 30, and the backing fabric 30 is wound around the backing fabric take-up roller 212 to form a backing fabric roll; a feeding component 22, the feeding component 22 is arranged between the cord fabric unwinding mechanism 21 and the covering fabric mechanism 3 along the transmission direction of the cord fabric 20, the feeding component 22 includes a rotatable feeding roller, the cord fabric 20 passes around the feeding roller, and the feeding roller is movably arranged along the transmission direction of the cord fabric 20 to transfer the cord fabric 20 to the inner ring 101. Specifically, the storage and output of the cord fabric are realized through the cord fabric unwinding mechanism 21, and the cord fabric 20 can be delivered to the inner ring 101 through the feeding component 22.

[0037] Specifically, one side of the cord fabric 20 is provided with an adhesive layer, the backing fabric 30 and the adhesive layer are wound around the storage roller 211 at intervals, the output shaft of the first driving component 213 is drivingly connected to the storage roller 211, the storage roller 211 and the backing fabric take-up roller 212 are drivingly connected through a conveyor belt, and a pneumatic damper is installed on the rotating shaft of the backing fabric take-up roller 212 to keep the backing fabric under a certain tension.

[0038] In some embodiments, the storage roller 211 is provided with three sets of photoelectric switches for detecting the coil diameter of the storage roller 211. The three sets of photoelectric switches are respectively arranged on the frame at intervals corresponding to low, medium and high coil diameters. The first driving component 213 can automatically start and stop according to the cord fabric storage amount, control the start and stop of the cord fabric unwinding mechanism, and ensure that there is always a stock of cord fabric.

[0039] In the covering machine of this embodiment, refer to Figures 4 - 6, the feeding rollers include a first feeding roller 221 and a second feeding roller 222 which are arranged at intervals, and the cord fabric 20 successively winds around the first feeding roller 221 and the second feeding roller 222; the feeding component 22 includes a slide rail 223 and a slider 224, the slider 224 is slidably connected with the slide rail 223, and the first feeding roller 221 and the second feeding roller 222 are fixedly connected with the slider 224 through a mounting frame. The slider drives the first feeding roller 221 and the second feeding roller 222 to move towards the wrapping mechanism 3, and the feeding component 22 reaches the feeding position, so that the cord fabric 20 is attached to the inner ring 101. As the workpiece 10 to be wrapped drives the cord fabric 20 to rotate, the slider drives the first feeding roller 221 and the second feeding roller 222 to move away from the wrapping mechanism 3, so that the feeding component 22 reaches the cutting position. At this time, the cord fabric 20 between the inner ring 101 and the storage roller 211 is still in a connected state. After cutting the cord fabric 20, the cord fabric head of the cord fabric 20 hangs on the second feeding roller 222. When the feeding component 22 moves to the feeding position again, the cord fabric head is sent to the inner ring 101.

[0040] Specifically, the first feeding roller 221 and the second feeding roller 222 are one-way rotating rollers, which prevent the first feeding roller 221 and the second feeding roller 222 from rotating in the reverse direction, so that the cord fabric 20 falls off from the feeding roller. The adhesive side of the cord fabric 20 is connected with the feeding roller, and through the mutual frictional force between the adhesive side and the feeding roller, the cord fabric is kept in a connected state with the feeding roller.

[0041] In the wrapping machine of this embodiment, refer to Figures 4 - 6 , the feeding component 22 includes a positioning frame 225, the positioning frame 225 is fixedly connected with the mounting frame, the positioning frame 225 includes a positioning channel for the cord fabric 20 to pass through, the width of the positioning channel matches the width of the cord fabric 20, the opening 226 of the positioning channel is connected with the first feeding roller 221, and the outlet 227 of the positioning channel is connected with the second feeding roller 222. By setting the positioning frame 225, the positioning of the cord fabric 20 can be completed, preventing the cord fabric 20 from running off before reaching the inner ring 101 and enabling it to be accurately attached to the workpiece 10 to be wrapped.

[0042] Specifically, at the opening 226, a guide plate is arranged in an inclined manner, so that the cord fabric 20 can smoothly enter the positioning channel along the guide plate.

[0043] In the wrapping machine of this embodiment, refer to Figures 4 - 6, the wrapper includes a cutting mechanism 5, and the cutting mechanism 5 includes: a cutting knife 51 for cutting the completed laminated cord fabric 20; a second driving member 52, the piston rod of the second driving member 52 is fixedly connected to the cutting knife 51 to control the reciprocating movement of the cutting knife 51; a fixed seat 53 for fixing the second driving member 52; wherein, the feeding member 22 has a feeding position where the cord fabric 20 abuts against the inner ring 101 and a cutting position where the cord fabric 20 is cut, and the cutting knife 51 is arranged corresponding to the cutting position. Specifically, by controlling the movement of the second driving member 52, the cutting knife 51 can reciprocate, thereby completing the cutting of the cord fabric 20.

[0044] In the wrapper of this embodiment, refer to Figures 5 - 6 , the cutting mechanism 5 includes a hollow mounting frame 54, one end of the mounting frame 54 is connected to the piston rod of the second driving member 52, the other end of the mounting frame 54 is fixedly provided with the cutting knife 51, and at least part of the feeding member 22 is arranged inside the mounting frame 54.

[0045] Specifically, the cutting edge of the cutting knife 51 is inclined relative to the horizontal direction, and the cutting edge of the cutting knife 51 has a tendency to approach the second feeding roller 222. When the cutting knife 51 cuts the cord fabric 20, the cord fabric 20 is located between the cutting knife 51 and the second feeding roller 222. With the impact and guidance of the cutting knife 51, the head of the cord fabric is lapped on the second feeding roller 222.

[0046] Specifically, when the feeding member 22 is in the feeding position, at this time the second feeding roller 222 passes through the mounting frame 54 to reach the inner ring 101. At this time, when the cutting knife 51 moves, it will collide with the mounting frame 54. When the feeding member 22 is in the cutting position, at this time the second feeding roller 222 moves out of the inside of the mounting frame 54, and the cutting knife 51 can move to complete the cutting of the cord fabric 20, so that the head of the cord fabric is lapped on the second feeding roller 222, which is convenient for automatic next wrapping.

[0047] In the wrapper of this embodiment, refer to Figure 1 , the cord fabric conveying mechanism further includes: a conveying roller 23 arranged along the conveying direction of the cord fabric 20 between the cord fabric unwinding mechanism 21 and the feeding roller, and the conveying roller 23 is used to guide the conveying direction of the cord fabric 20; a guiding roller 24 arranged along the conveying direction of the cord fabric 20 between the conveying roller 23 and the feeding member 22, and the guiding roller 24 is used to guide the cord fabric 20 to the inner ring 101. Specifically, the conveying roller 23 and the guiding roller 24 are kept in contact with the back glue surface of the cord fabric 20.

[0048] In the wrapper of this embodiment, refer to Figures 5 - 6, the wrapping roller 31 includes a hemming groove that matches the width of the item 10 to be wrapped, so that both sides of the cord fabric 20 are bent towards the side surfaces of the item 10 to be wrapped; the wrapping mechanism 3 includes a third driving member 32, and the output shaft of the third driving member 32 is drivingly connected to the wrapping roller 31 to drive the item 10 to be wrapped to rotate by driving the rotation of the wrapping roller 31. Specifically, there are multiple wrapping rollers 31, and multiple wrapping rollers 31 are all driving rollers, so as to drive the item 10 to be wrapped to rotate actively. The rotation of the item 10 to be wrapped can pull the cord fabric 20 to complete the fitting synchronously. The cord fabric 20 is fitted to the inner ring 101 and the two sides of the cord fabric are gradually bent by multiple wrapping rollers 31. The third driving member 32 drives multiple wrapping rollers 31 to rotate simultaneously and starts and stops automatically according to the program setting.

[0049] Specifically, by controlling the outer diameter of the wrapping roller 31 or the number of teeth of the driving gear, etc., multiple wrapping rollers 31 have different speed ratios, and the rotation speeds of multiple wrapping rollers 31 gradually increase in sequence, so as to maintain the tension on the cord fabric 20 and make the cord fabric 20 fit more evenly and tightly.

[0050] In some embodiments, there are at least three wrapping rollers 31, and at least three wrapping rollers 31 complete the processes of flattening the cord fabric onto the inner ring 101, initially bending the side edges of the cord fabric 20, and further bending the side edges of the cord fabric 20 in sequence.

[0051] In some embodiments, the wrapping machine includes a loading and unloading manipulator, and the loading and unloading manipulator is used for loading and unloading the item 10 to be wrapped, realizing full-automatic wrapping of the wrapping machine.

[0052] The working principle of the wrapping machine in this embodiment is as follows:

[0053] The peeling and guiding of the cord fabric 20 are completed by the cord fabric guiding mechanism 21, and the cord fabric 20 is guided to the feeding member 22. The cord fabric 20 enters the positioning channel after passing around the first feeding roller 221, and then the cord fabric passes around the second feeding roller 222. The slider 224 drives the second feeding roller 222 to move towards the wrapping mechanism 3. At this time, the feeding member 22 reaches the feeding position, and the head of the cord fabric is fitted to the inner ring 101. As the item 10 to be wrapped rotates, the cord fabric 20 is pulled. At the same time, the wrapping roller 31 rolls the cord fabric 20 onto the inner ring 101 and bends both sides of the cord fabric 20 towards the side surfaces of the item 10 to be wrapped. Then, the pressing roller 41 presses the bent side of the cord fabric 20 against the item 10 to be wrapped. At the same time, the slider drives the second feeding roller 222 to move away from the wrapping mechanism 3, so that the feeding member 22 reaches the cutting position. When the item 10 to be wrapped rotates one week to complete the wrapping, the moving cutting knife 51 cuts the cord fabric 20, so that the head of the cord fabric is lapped on the second feeding roller 222, and the item 10 to be wrapped is loaded and unloaded, and the cycle is repeated in sequence.
