Technical Field

[0001] The utility model belongs to the field of apex glue laminating machines, in particular to a horizontal apex glue laminating machine for agricultural tires and engineering tires. Background Art

[0002] In the prior art, the apex rubber is processed and produced, and then the steel ring is placed on a laminating machine so that the apex rubber is laminated to the outer wall of the steel ring, and finally the processed product is taken away to form a fully automatic production line.

[0003] However, the above production lines can only process steel rims of the same diameter. The diameter of the steel rims ranges widely, mostly from 20 inches to 60 inches, and the longest diameter can reach 1.6 meters. Due to the different specifications of the steel rims produced, multiple devices are generally required to process the corresponding sizes. This automated production line is more suitable for processing manufacturers with large production needs.

[0004] For processing manufacturers with small production needs, the steel rims they process often face the situation of a large span of processing specifications and small production output. At this time, it will consume a lot of financial resources to purchase corresponding production lines according to the specifications of the steel rims, so the production line is not suitable for small-scale manufacturers. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a horizontal apex glue laminating machine for farm tires and engineering tires, which can be adjusted according to the diameters of steel rims of different specifications, and then the apex glue is manually assisted to meet the production of steel rims of most specifications. It has a compact structure, saves money, and is suitable for small-scale production.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a horizontal apex glue laminating machine for farm tires and engineering tires, comprising a main frame, a placement platform rotated above the main frame by a driving device, a plurality of support mechanisms are arranged around the center of a circle on the placement platform, the support mechanism comprises a support ring plate, a plurality of groups of the support ring plates are radially coordinated to extend and retract to support the inner wall of the steel ring, a downwardly pressing rubber roller is arranged above the placement platform to make the apex glue and the steel ring fit;

[0007] It comprises an expansion and contraction mechanism, which drives a plurality of support ring plates to move radially, so as to be suitable for steel rings with different diameters.

[0008] Furthermore, the placement platform includes a turntable and a tray, the multiple groups of support mechanisms are arranged at the upper end of the turntable, and the support mechanism includes a rubber supporting plate that is arranged on the outer side of the support ring plate and expands and contracts therewith.

[0009] Furthermore, the supporting mechanism includes an optical axis assembly, a fixed block and a movable block are arranged along the optical axis of the optical axis assembly, the support ring plate and the rubber support plate are both arranged on the movable block, and a pushing cylinder for driving the support ring plate to extend and retract is arranged on the fixed block.

[0010] Furthermore, the expansion and contraction mechanism includes an expansion and contraction screw rotatably mounted on a fixed seat in the optical axis assembly, and the expansion and contraction screw is threadedly connected to the fixed block.

[0011] Furthermore, a side pipe rack is provided on one side of the main pipe rack, and the rubber pressing roller can slide axially on the side pipe rack to match with steel rings of different diameters.

[0012] Furthermore, a crossbeam is slidably disposed on the support plate of the side pipe rack via a guide rail, and the rubber pressing roller is liftably disposed at the end of the crossbeam.

[0013] Furthermore, the tray is pressed above the turntable and is located in the same plane as the plurality of rubber supporting plates, and a sliding groove is provided on the tray to guide the sliding path of the support ring plate and the rubber supporting plates.

[0014] Furthermore, the expansion and contraction mechanism includes a rotating main shaft passing through the turntable and a main bevel gear arranged at the upper end of the rotating main shaft, and a slave bevel gear meshing with the main bevel gear is arranged on the end of the fixed seat close to the center of the turntable, and the slave bevel gear drives the expansion and contraction screw to rotate.

[0016] Furthermore, an adjusting rod which is rotatably connected to the side pipe rack through a thread is provided at the lower end of the cross beam.

[0017] The advantages and positive effects of the utility model are:

[0018] 1. Due to the adoption of the above technical solution, by setting the placement platform above the main frame, its height is convenient for the operator to process, and the support ring plates in the multiple support mechanisms automatically shrink radially, which can complete the support and fixation of the inner wall of the steel ring and the release of support after processing. The operator only needs to manually fit the triangle glue to the outer wall of the steel ring, and the driving device will drive the placement platform to rotate, thereby improving the processing efficiency. The expansion and contraction mechanism causes the push cylinders in the multiple support mechanisms to move radially. By changing the initial position of the push cylinders, the diameter of the rings presented by the multiple support ring plates has been changed, which can be applied to steel rings of different diameters.

[0019] 2. The driving device rotates by meshing the outer ring gear with the driving gear, which makes the transmission effect of the placement platform more precise and easy to control. The meshing of the main bevel gear in the expansion and contraction mechanism with multiple slave bevel gears can accurately adjust the position of the support ring plates in multiple groups of support mechanisms at the same time.

[0020] 3. When the operator fits the apex with the rotation of the placement platform, the downward pressing rubber roller strengthens the fit between the apex and the steel ring, improving the quality of the finished product. In order to match the steel rings of different diameters, the rubber pressing roller changes through the axial movement of the crossbeam. BRIEF DESCRIPTION OF THE DRAWINGS

The support mechanisms include an arc-shaped support ring plate 6. The plurality of support ring plates 6 are radially coordinated to extend and retract to support the inner wall of the steel ring. A glue pressing roller 51 can be pressed down above the placement platform to make the apex glue fit the steel ring. The glue pressing roller 51 is conical, and its contact surface can match the apex glue and the steel ring.

[0035] The placement platform includes a turntable 2 and a tray 3, and multiple groups of supporting mechanisms are arranged around the upper end of the turntable 2. The supporting mechanism includes a rubber supporting plate 7 arranged on the outside of the support ring plate 6 and an optical axis assembly guiding the telescopic path of the support ring plate 6. The optical axis assembly includes a fixed seat 12 and an optical axis 121 arranged in the fixed seat 12. Two optical axes 121 are relatively arranged on the fixed seat 12. A fixed block 13 and a moving block 131 are slidably connected on the optical axis 121. The support ring plate 6 and the rubber supporting plate 7 are connected to the moving block 131. A pushing cylinder 61 for driving the support ring plate 6 to extend and retract is arranged on the fixed block 13, and the fixed block 13 is driven to move by the expansion and contraction mechanism.

[0036] The tray 3 is pressed onto the turntable 2 and is located in the same plane as the multiple glue supporting plates 7. A sliding groove is provided on the tray 2 to guide the sliding path of the support ring plate 6 and the degumming plate 7, and a through groove is left to expose the pushing cylinder 61. The tray 2 is connected to the turntable 2 by a connecting member, such as a bolt.

[0037] The driving device includes an outer ring gear 21 sleeved on the lower end of the turntable 2, a B motor 9 is arranged on one side of the main frame 1, and a driving gear 91 meshing with the outer ring gear 21 is arranged at the output end of the B motor 9, thereby driving the placement platform to rotate.

[0038] The expansion and contraction mechanism is provided with multiple groups matching the number of the supporting mechanisms. The tensioning mechanism is used to drive the multiple support ring plates 6 to move radially, which has been matched with steel rings of different diameters, including an expansion and contraction screw 122 rotatably arranged on the fixed seat 12. The expansion and contraction screw 122 is threadedly connected to the fixed block 13 and passes through the moving block 131. The initial position of the pushing cylinder 61 is changed by the expansion and contraction screw 122.

[0039] The tensioning mechanism also includes a rotating main shaft 82 that passes through the turntable 2. A main bevel gear 81 is arranged at the upper end of the rotating main shaft 82. A slave bevel gear 123 that meshes with the main bevel gear 81 is arranged at the end of the fixed seat 12 close to the center of the turntable 2. The slave bevel gear 123 is linked to the expansion and contraction screw 122, and the rotating main shaft 82 is driven by the A motor 8 arranged in the main frame 1.

[0040] A guide rail 41 is arranged on the support plate of the side pipe rack 10, and a crossbeam 4 is connected to the slider of the guide rail 41. In order to drive the crossbeam 4 to move axially, an adjusting rod 42 is rotatably arranged at the lower end of the crossbeam 4, and the other end of the adjusting rod 42 is threadedly connected to the side pipe rack 10. The rubber pressing roller 51 is driven to move axially by rotating the adjusting rod 42. A downward pressure cylinder 5 for driving the rubber pressing roller 51 to move up and down is arranged at the end of the crossbeam 4.

[0041] The rotation of the driving adjustment rod 42 can be driven automatically or manually. In the present embodiment, it is manually driven by the hand wheel 11. Specifically, an A sprocket 111 is provided on the adjustment rod 42, and a B sprocket 112 which is linked by a chain is provided below the side pipe frame 10 opposite to the A sprocket 111. The B sprocket 112 is driven by rotating the hand wheel 11.

[0042] The working process of this example:

[0043] The steel ring is placed on the tray 3, and multiple push cylinders 61 drive the corresponding support ring plate 6 and the rubber supporting plate 7 to push outward to achieve radial extension, support the inner wall of the steel ring to prevent the steel ring from running, and the operator fits the apex rubber to the outer wall of the steel ring. At this time, the downward pressure cylinder 5 drives the rubber pressing roller 51 to press the fitting part of the apex rubber and the steel ring. The B motor 9 drives the steel ring on the tray 3 to rotate together through the meshing of the driving gear 91 and the outer ring gear 21. The operator continues to fit the apex rubber with the rotation of the tray 3 until the initial end of the apex rubber turns back, and the downward pressure rubber pressing roller 51 rises and lifts up. The operator then manually fits the two ends of the apex rubber together to complete the processing of the steel ring;

[0044] At this time, in order to strengthen the fit between the apex rubber and the steel ring, the glue pressing roller 51 is pressed down again, and the tray 3 is rotated again to press the apex rubber and the steel ring. After the processing is completed, multiple pushing cylinders 61 drive the corresponding support ring plates 6 and rubber supporting plates 7 to retract inward, realize radial retraction, and release the fixation on the inner wall of the steel ring.

[0045] If the diameter of the steel ring changes, the A motor 8 drives the rotating main shaft 82 to rotate the main bevel gear 81, and the slave bevel gear 123 meshes with the main bevel gear 81 to link the expansion and contraction screw 122 to make the pushing cylinder 61 on the fixed block 13 move inward or outward along the optical axis 121, and the support ring plate 6 connected to the output end of the pushing cylinder 61 also drives the moving block 131 to move together, and through the joint linkage of multiple groups of expansion and contraction mechanisms, the support ring plates 6 in the multiple groups of support mechanisms change radially.

[0046] In order to match the pressing position of steel rings of different diameters, the hand wheel 11 is shaken, and the adjusting rod 42 is driven to rotate through the linkage of the A sprocket 111 and the B sprocket 112, driving the crossbeam to achieve axial displacement, so as to match the diameter of the steel ring.
