Description

Technical Field

[0001] This invention relates to the field of tire forming production technology, and in particular to a quick loading and unloading mechanism for the lining roller of a tire forming machine. Background Technology

[0002] Tire forming machines are specialized equipment used in tire manufacturing to assemble semi-finished materials. Their function is to assemble and bond semi-finished components such as tread rubber, carcass rubber, inner lining rubber, cord fabric, and steel wire rings according to process requirements to form a tire blank. To save space, semi-finished materials such as tread rubber, carcass rubber, inner lining rubber, and cord fabric are typically prepared and loaded into the machine using a roller rolling method. This roller rolling method also facilitates material transfer and improves the flexibility of the tire forming process. However, since the surfaces of semi-finished materials such as tread rubber, carcass rubber, inner lining rubber, and cord fabric are all made of rubber, adhesion can occur between layers during rolling. Therefore, a lining layer needs to be added during the semi-finished product rolling process for isolation. The lining is then recycled and rolled back during the semi-finished product production process, allowing for reuse.

[0003] Chinese utility model patent CN202670845U discloses a lining machine for tire component manufacturing. Its technical solution involves winding the lining roll to be recycled onto a take-up roller, and then rotating the take-up roller via a motor to achieve winding. It is evident that existing lining recycling and unloading devices mostly use a motor to directly drive a square shaft, which in turn drives the lining to wind and recycle it. After a roll of lining is fully wound, workers enter the equipment to remove it and place it in a designated area. Manual handling not only reduces production efficiency but also increases the labor intensity of workers. Furthermore, operators often need to enter the machine, which poses a safety hazard. Therefore, a rapid loading and unloading mechanism for lining rollers is needed to achieve quick and convenient loading and unloading of lining rollers, thereby improving the production efficiency and safety of tire forming. Summary of the Invention

[0004] Therefore, the present invention provides a quick loading and unloading mechanism for the lining roller of a tire forming machine, in order to solve the problems of low loading and unloading efficiency and poor safety of manual handling of the lining roller in the prior art.

[0005] To achieve the above objectives, the present invention provides a quick loading and unloading mechanism for the lining roller of a tire forming machine, comprising: The drive take-up unit is capable of contacting or separating from the lining roller. When in contact with the lining roller, the drive take-up unit can perform frictional drive on both sides of the lining roller, causing the lining roller to rotate axially. The inner support section is used to support the convex shaft at the outer end of one side of the lining roller, and the inner support section can be raised and lowered. The outer support section is used to support the convex shaft at the outer end of the other side of the lining roller. The outer support section can also avoid the loading and unloading path of the lining roller by moving laterally. The loading and unloading transfer unit is used to transfer the fully loaded liner roller that has been wound and recycled to the outside of the mechanism. The loading and unloading transfer unit can also transfer the empty liner roller to be wound and recycled to the inner support unit and the outer support unit for mounting.

[0006] Furthermore, the drive take-up unit includes a rubber wheel for frictionally driving the lining roller, a rotating arm for controlling the contact or separation of the rubber wheel from the lining roller, and a drive motor for driving the rubber wheel to rotate. The drive motor is mounted on a motor bracket, and symmetrical rotating arms are arranged on both sides of the motor bracket. One end of each rotating arm is hinged to the motor bracket, and the other end of each rotating arm is connected to a first telescopic cylinder and a second telescopic cylinder, respectively. The first telescopic cylinder and the second telescopic cylinder can swing the two rotating arms by extending and retracting.

[0007] Furthermore, the rubber wheel is mounted between the two rotating arms, with one side of the rubber wheel passing through one of the rotating arms and connected to the drive motor via a transmission gear. The drive motor drives the rubber wheel to rotate through the transmission gear.

[0008] Furthermore, the inner support unit includes a fixed frame plate fixedly mounted on the main frame, a third telescopic cylinder fixedly mounted at the bottom of the fixed frame plate, and a lifting seat slidably mounted on the fixed frame plate; The third telescopic cylinder is connected to the lifting seat. The third telescopic cylinder can extend and retract to make the lifting seat slide on the fixed frame plate, thereby raising and lowering the lifting seat.

[0009] Furthermore, a longitudinal slide rail is provided on the fixed frame plate, and the lifting seat is connected to the fixed frame plate through the longitudinal slide rail.

[0010] Furthermore, the top of the lifting seat is provided with a notch, through which the lifting seat supports and lifts the outer end convex shaft of the lining roller; The fixed frame plate is equipped with an inner limit roller, which is used to limit the height of the lifting seat, and the inner limit roller can rotate freely. Two inner frame holding rollers are installed in the notch at the top of the lifting platform, and both inner frame holding rollers can rotate freely.

[0011] Furthermore, the external support unit includes a fixed frame fixedly mounted on the main frame, a boom slidably mounted on the fixed frame, and a support arm hinged to the boom; A transverse slide rail is provided on the fixed frame, and the boom is connected to the fixed frame via the transverse slide rail. A fourth telescopic cylinder is fixedly installed on the fixed frame and is connected to the boom. The fourth telescopic cylinder is used to control the lateral movement of the boom on the fixed frame by telescopic control.

[0012] Furthermore, a fifth telescopic cylinder is also installed on the boom, which is longitudinally fixed to the boom by a fixing plate on the boom. One end of the support arm is provided with a notch, and two freely rotatable outer frame holding rollers are provided in the notch. The other end of the support arm is connected to a fifth telescopic cylinder arranged longitudinally. The fifth telescopic cylinder is used to control the rotation of the support arm relative to the boom through telescopic control to raise and lower the end of the support arm. The boom end is also equipped with a freely rotating outer limit roller, which is used to limit the height of the boom end lifting.

[0013] Furthermore, the loading and unloading transfer unit includes a transfer track horizontally fixed on the main frame and a transfer trolley set on the transfer track; One end of the transfer track is located inside the main frame, and the other end extends outside the main frame. The transfer trolley is used to transfer the lining roller and can move on the transfer track.

[0014] Furthermore, a lifting platform is hinged to one end of the transfer track that extends outside the main frame. One side of the lifting platform is hinged to the transfer track, and an extension plate is fixedly installed on the other side. The extension plate is inclined relative to the lifting platform. The lifting platform is also connected to a sixth telescopic cylinder, which is used to control the rotation of the lifting platform, making the lifting platform horizontal or tilted. When the lifting platform is horizontal, the lifting platform is at the same height as the transfer track; when the lifting platform is tilted, the extension plate is in contact with the ground and is horizontal.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting the drive winding part to drive the lining roller to rotate through friction, the lining roller can rotate without being sleeved on the square shaft. At the same time, the drive winding part can also be separated from the lining roller, making it easier to install and unload the lining roller. The lining roller is supported by the lifting of the inner support part and the outer support part on both sides, which can realize the automated loading and unloading of the lining roller and is more compatible with the driving method of the drive winding part. By setting the loading and unloading transfer part, the fully loaded lining roller is transferred to the outside of the lining roller quick loading and unloading mechanism, and the empty lining roller is transferred to the inside of the lining roller quick loading and unloading mechanism, realizing automated transfer, effectively simplifying the loading and unloading process of the lining roller, reducing manual operation links, and improving the loading and unloading efficiency of the lining roller while ensuring the safety of loading and unloading.

[0022] Please see Figure 1 and Figure 2 As shown, this embodiment provides a quick loading and unloading mechanism for the lining roller of a tire forming machine. It includes a main frame 1, a drive winding unit 2, an inner support unit 3, an outer support unit 4, and a loading and unloading transfer unit 5; In this embodiment, the inner support part 3 and the outer support part 4 support the outer end convex shafts on both sides of the lining roller 6, and the drive winding part 2 drives the wheel circles on both sides of the lining roller 6 to rotate axially, thereby realizing the winding and recovery of the lining. At the same time, both the inner support part 3 and the outer support part 4 have lifting functions. By lifting the inner support part 3 and the outer support part 4, the lining roller 6 can be raised or lowered, realizing the rapid loading and unloading of the lining roller 6. In addition, this embodiment also provides a loading and unloading transfer part 5 for loading and unloading. The transfer unit 5 can transfer the fully loaded lining roller 6 that has completed winding and recycling to the outside of the mechanism, and can also transfer the empty lining roller 6 that is to be wound and recycled to the corresponding position inside the mechanism. It can be quickly installed by controlling the lifting support of the inner support unit 3 and the outer support unit 4. The drive winding unit 2 can achieve contact and separation with the lining roller 6. When the drive winding unit 2 contacts the lining roller 6, it can drive the lining roller 6 to rotate to wind up the lining. When the drive winding unit 2 separates from the lining roller 6, it facilitates the quick loading and unloading of the lining roller 6.

[0023] Please continue reading. Figure 3 As shown, specifically, the drive take-up unit 2 includes a rubber wheel 202 for rubbing the two sides of the lining roller 6, a rotating arm 201 for controlling the contact or separation of the rubber wheel 202 from the lining roller 6, and a drive motor 203 for driving the rubber wheel 202 to rotate; wherein, the drive motor 203 is mounted on a motor bracket 207, the motor bracket 207 is fixedly mounted on the bottom surface of the main frame 1, and the rotating arms 201 are symmetrically arranged hinged on both sides of the motor bracket 207, the rotating arms 201 being able to rotate relative to the motor bracket 202. 07 rotates, the rubber wheel 202 is mounted between the two rotating arms 201, and the rubber wheel 202 can rotate axially. One side of the rubber wheel 202 passes through one of the rotating arms 201 and is connected to the drive motor 203 through the transmission gear 204. The drive motor 203 can make the rubber wheel 202 rotate. At the same time, one side of the two rotating arms 201 is connected to the first telescopic cylinder 205 and the second telescopic cylinder 206 respectively, and the first telescopic cylinder 205 and the second telescopic cylinder 206 are both fixedly mounted on the side wall of the main frame 1. By controlling the extension and retraction of the first telescopic cylinder 205 and the second telescopic cylinder 206, the two rotating arms 201 can be driven to rotate, thereby realizing the contact and separation of the rubber wheel 202 and the lining roller 6. When the first telescopic cylinder 205 and the second telescopic cylinder 206 are extended, the rubber wheel 202 squeezes the two wheel circles of the lining roller 6. At this time, the drive motor 203 rotates, and drives the rubber wheel 202 to rotate through the transmission gear 204, thereby realizing the friction drive of the lining roller 6.

[0024] Please continue reading. Figure 4 As shown, the inner support part 3 is used to support the convex shaft at the outer end of one side of the lining roller 6; Specifically, the inner support unit 3 includes a fixed frame plate 304 fixedly mounted on the main frame 1, a third telescopic cylinder 303 fixedly mounted on the bottom of the fixed frame plate 304, and a lifting seat 301 slidably mounted on the fixed frame plate 304. The fixed frame plate 304 is provided with a longitudinal slide rail 305, and the lifting seat 301 is connected to the fixed frame plate 304 through the longitudinal slide rail 305. The lifting seat 301 can move longitudinally relative to the fixed frame plate 304. At the same time, the lifting seat 301 is connected to the third telescopic cylinder 303, and the longitudinal movement is driven by the extension and retraction of the third telescopic cylinder 303. The top of the lifting seat 301 is provided with a notch, and two freely rotatable inner support rollers 302 are provided in the notch. The fixed frame plate 304 is also provided with freely rotatable inner limit rollers 306. During the installation of the lining roller 6, the third telescopic cylinder 303 retracts, causing the lifting seat 301 to move down to its lowest point. At this time, the convex shaft at the outer end of one side of the lining roller 6 extends above the top notch of the lifting seat 301. Then, the third telescopic cylinder 303 extends, causing the notch of the lifting seat 301 to abut against the convex shaft at the outer end of one side of the lining roller 6 and move upward to the inner limit roller 306. The two inner support rollers 302 on the lifting seat 301 and the inner limit roller 306 on the fixed frame plate 304 support one side of the lining roller 6. At the same time, since both inner support rollers 302 and one inner limit roller 306 can rotate automatically, the friction between the outer end convex shaft and the inner support part 3 can be reduced when the lining roller 6 rotates, which facilitates the rotation and winding of the lining roller 6.

[0025] Please continue reading. Figure 5 As shown, the outer support part 4 is used to support the convex shaft at the outer end of the other side of the lining roller 6; Specifically, the outer support unit 4 includes a fixed frame 401 fixedly mounted on the main frame 1, a boom 404 slidably mounted on the fixed frame 401, and a support arm 406 hinged to the boom 404; wherein, the fixed frame 401 is provided with a transverse slide rail 402, the boom 404 is connected to the fixed frame 401 through the transverse slide rail 402, a fourth telescopic cylinder 403 is fixedly mounted on the fixed frame 401, the fourth telescopic cylinder 403 is connected to the boom 404, and the fourth telescopic cylinder 403 controls the transverse movement of the boom 404 on the fixed frame 401 by telescopic control; A fifth telescopic cylinder 407 is also provided on the boom 404. The fifth telescopic cylinder 407 is longitudinally fixed to the boom 404 via a fixing plate 405. One end of the support arm 406 is provided with a notch, in which two freely rotatable outer frame holding rollers 408 are provided. The other end of the support arm 406 is connected to the longitudinally arranged fifth telescopic cylinder 407. The extension of the fifth telescopic cylinder 407 causes one side of the support arm 406 to descend. Since the support arm 406 and the boom 404 are hinged... The support arm 406 is rotatable relative to the boom 404. When one side of the support arm 406 is lowered, the other side is raised by the rotation of the hinge, so that the notch at the end of the support arm 406 supports the convex shaft at the outer end of the lining roller 6. At the same time, the end of the boom 404 is also provided with an outer limit roller 409 that can rotate freely. The two outer support rollers 408 in the notch abut against the convex shaft at the outer end of the lining roller 6 and rise, so that the upper part of the convex shaft at the outer end of the lining roller 6 abuts against the outer limit roller 409, thereby supporting the lining roller 6. During the installation of the lining roller 6, the fourth telescopic cylinder 403 is first retracted to move the boom 404 laterally, leaving space for the lining roller 6 to enter. After the lining roller 6 enters, the fourth telescopic cylinder 403 is extended to move the boom 404 to move the support arm 406 to below the convex shaft at the outer end of the lining roller 6. The fifth telescopic cylinder 407 is extended to raise one end of the support arm 406, lifting and supporting the convex shaft at the outer end of the lining roller 6. Since the two outer support rollers 408 and one outer limit roller 409 can rotate freely, the friction between the outer convex shaft and the outer support part 4 can be reduced when the lining roller 6 rotates, making it easier for the lining roller 6 to rotate and be wound.

[0026] In this embodiment, the support arm 406 is rotated to raise one end of the notch. When holding the convex shaft at the outer end of the lining roller 6, the notch of the support arm 406 is in a horizontal state. When the lining roller 6 needs to be unloaded, the horizontal state of the notch can be changed to an inclined state by rotating one end of the support arm 406 to lower the notch. The front end of the notch is lower, which can avoid the convex shaft at the outer end of the lining roller 6. This allows the boom 404 to move laterally on the fixed frame 401 without being blocked by the convex shaft at the outer end of the lining roller 6, thereby completing the lateral movement of the boom 404 and avoiding the unloading path of the lining roller 6.

[0027] Please continue reading. Figure 6 As shown, the loading and unloading transfer unit 5 is used to transfer the fully loaded liner roller 6 that has completed winding and recycling to the outside of the mechanism, and to transfer the empty liner roller 6 that is to be wound and recycled to the corresponding position inside the mechanism. Specifically, the loading and unloading transfer unit 5 includes a transfer track 501 horizontally fixed on the main frame 1 and a transfer trolley 502 set on the transfer track 501. One end of the transfer track 501 is located inside the main frame 1, and the other end extends outside the main frame 1. A lifting platform 503 is hinged to the end extending outside the main frame 1. The lifting platform 503 can rotate relative to the transfer track 501. The lifting platform 503 is also connected to a sixth telescopic cylinder 504. When the sixth telescopic cylinder 504 extends, the lifting platform 503 rotates to a horizontal state, level with the height of the transfer track 501. When the sixth telescopic cylinder 504 retracts, the lifting platform 503 rotates to lower one side, and the lifting platform 503 is in an inclined state. An extension plate 505 is also fixedly set on one side of the lifting platform 503. When the sixth telescopic cylinder 504 retracts to tilt the lifting platform 503, the extension plate 505 on one side of the lifting platform 503 abuts against the ground, and the extension plate 505 is in a horizontal state. During the installation of the lining roller 6, the lining roller 6 is moved to the horizontal extension plate 505 on the ground. The sixth telescopic cylinder 504 extends, causing the lifting platform 503 to rotate and lift the lining roller 6. When the lifting platform 503 rotates to a horizontal position, the lining roller 6 rolls onto the transfer trolley 502 of the transfer track 501. The transfer trolley 502 drives the lining roller 6 to move on the transfer track 501, so that the lining roller 6 enters the main frame 1. Then, through the lifting support of the inner support part 3 and the outer support part 4, the lining roller 6 is quickly installed.
