Specific embodiments

[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0026] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0027] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are generally in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms do not limit the present invention.

[0028] In order to solve the problem that the push plate, the positive wrapping finger seat, the capsule seat and the main shaft in the prior art are prone to seizure when they cooperate, the present invention provides a positive and negative wrapping device and a molding machine.

[0029] Such as Figures 1 to 7A provided front and back wrapping device includes a base 10, a main shaft 20, a capsule assembly 30, a front wrapping finger assembly 40, and a push plate assembly 50. The main shaft 20 is connected to the base 10. The capsule assembly 30 has a bushing 31 and a capsule seat 32. Both the bushing 31 and the capsule seat 32 are sleeved outside the main shaft 20, and the bushing 31 is located between the capsule seat 32 and the main shaft 20. The front wrapping finger assembly 40 is connected to the base 10, sleeved outside the main shaft 20, and is spaced from the main shaft 20. The push plate assembly 50 is connected to the base 10, sleeved outside the main shaft 20, and is spaced from the main shaft 20.

[0030] In this embodiment, by arranging the bushing 31 between the capsule seat 32 and the main shaft 20, the capsule seat 32 and the main shaft 20 do not directly contact each other. Moreover, there are spaces between the front wrapping finger assembly 40 and the main shaft 20, and between the push plate assembly 50 and the main shaft 20. In this way, none of the capsule seat 32, the front wrapping finger assembly 40, and the push plate assembly 50 directly contacts the main shaft 20, thereby avoiding the problem of jamming with the main shaft 20, improving the working stability of the molding machine, reducing costs, and improving work efficiency.

[0031] In this embodiment, along the axial direction of the main shaft 20, the length of the bushing 31 is greater than or equal to the length of the capsule seat 32, so as to avoid the direct contact between the capsule seat 32 and the main shaft 20. The bushing 31 in this embodiment is set in a sleeve shape and extends along the axial direction of the main shaft 20. The length of the bushing 31 refers to the distance between both ends of the bushing 31.

[0032] In this embodiment, the capsule seat 32 includes a seat body 321 for installing a capsule, a guide seat 322, and a guide rod 323. The seat body 321 is axially movably sleeved outside the main shaft 20. The guide seat 322 is axially movably sleeved outside the main shaft 20. There are bushings 31 between the seat body 321 and the main shaft 20, and between the guide seat 322 and the main shaft 20. The guide rod 323 is arranged between the seat body 321 and the guide seat 322, and both ends of the guide rod 323 are respectively connected to the seat body 321 and the guide seat 322. The guide seat 322 drives the seat body 321 to move axially synchronously through the guide rod 323. There are multiple guide rods 323 in this embodiment, which are set in a long rod shape and extend along the axial direction of the main shaft 20, connecting the seat body 321 and the guide rod 323 together. The multiple guide rods 323 are arranged circumferentially along the main shaft 20.

[0033] In this embodiment, there are multiple bushings 31, including a first bushing 311 and a second bushing 312. The first bushing 311 is located between the seat body 321 and the main shaft 20, and the second bushing 312 is located between the guide seat 322 and the main shaft 20. The first bushing 311 and the second bushing 312 are spaced or integrally arranged, so as to isolate the capsule seat 32 from the main shaft 20. As Figure 3As shown, considering cost issues, in this embodiment, the first bushing 311 and the second bushing 312 are arranged at intervals. The length of the first bushing 311 is set to be greater than the axial length of the guide seat 322, and the length of the second bushing 312 is greater than the axial length of the guide seat 322. No bushing 31 is arranged between the first bushing 311 and the second bushing 312. The connection of the guide rod 323 enables the capsule seat 32, the first bushing 311, and the second bushing 312 to move synchronously, thereby reducing costs. Of course, an integrated setting method can also be adopted, that is, bushings 31 are arranged between the seat body 321 and the guide seat 322, thereby improving the movement stability of the capsule seat 32.

[0034] In this embodiment, the capsule assembly 30 further includes a capsule driving member 33. The capsule driving member 33 is connected to the base 10 and is drivingly connected to the guide rod 323 to drive the capsule seat 32 to move axially. Specifically, an installation plate is arranged on the base 10. The installation plate is set as a square plate, and a through hole is arranged in the middle of the square plate so that it can be sleeved on the main shaft 20 and is arranged at an interval from the main shaft 20. The capsule driving member 33 is fixed on the installation plate. Thus, the capsule driving member 33 can drive the guide seat 322 to drive the guide rod 323 and the seat body 321 to move axially to perform the reverse wrapping operation. Optionally, as Figure 2 shown, the capsule driving member 33 can be arranged in a manner that a servo motor drives a sprocket group, and the sprocket group drives a lead screw. Compared with driving by an oil cylinder or a cylinder, the servo motor drive has higher precision and is beneficial to improving the quality of tire blank forming. Among them, the servo motor and the sprocket group are both arranged on the installation plate. The sprocket group drives the lead screw to move axially. The lead screw is connected to the guide seat 322, and the lead screw drives the guide seat 322 to move axially, thereby driving the seat body 321 to move axially. Of course, for the processing of tire blanks with lower precision requirements, an oil cylinder or a cylinder can also be used for driving, and the seat body 321 can also be driven to move axially.

[0035] In this embodiment, the capsule assembly 30 further includes an exhaust valve 34. The exhaust valve 34 is connected to the guide seat 322 to assist in exhausting the capsule. Specifically, the exhaust valve 34 is arranged on the side of the guide seat 322 away from the seat body 321 to assist in quickly exhausting the capsule while avoiding interfering with other components. Optionally, two exhaust valves 34 can be arranged, thereby increasing the exhaust speed of the capsule and shortening the timing of capsule reverse wrapping. Of course, according to the actual exhaust needs, the number of exhaust valves 34 can be adjusted, and it can also be arranged as three, four or more. If one exhaust valve 34 meets the exhaust needs of the capsule, only one can also be arranged.

[0036] As Figure 4 、 Figure 5As shown in the figure, in this embodiment, the positive wrapping finger means that the component 40 includes a positive wrapping finger mechanism 41, a mounting seat 42, and a positive wrapping driving member 43. The positive wrapping finger mechanism 41 is sleeved outside the main shaft 20 at intervals; the mounting seat 42 is movably arranged relative to the base 10, and the positive wrapping finger mechanism 41 is connected to the mounting seat 42; the positive wrapping driving member 43 is connected to the base 10 and is drivingly connected to the mounting seat 42. The positive wrapping driving member 43 drives the mounting seat 42 to move along the axial direction of the main shaft 20, so as to complete the positive wrapping action. Specifically, along the axial direction of the main shaft 20, the mounting plate, the mounting seat 42, and the positive wrapping finger mechanism 41 are sleeved on the outer peripheral side of the main shaft 20 in sequence, and all three are arranged at intervals with the main shaft 20; the mounting plate serves as a fixing device for the positive wrapping driving member 43 and is also a fixing device for the above-mentioned capsule driving member 33; the mounting seat 42 serves as a supporting device for the positive wrapping driving member 43. The positive wrapping finger mechanism 41 is movably arranged relative to the base 10 through the mounting seat 42. In this way, the positive wrapping driving member 43 can drive the mounting seat 42 to move axially relative to the main shaft 20, thereby driving the positive wrapping finger mechanism 41 to move axially to complete the positive wrapping work; the mounting seat 42 is arranged as a square structure with a certain thickness, and a through hole is arranged in the middle of the square structure to be sleeved on the outer peripheral side of the main shaft 20. Reinforcing plates are arranged on both the side of the mounting seat 42 close to the mounting plate and the side close to the positive wrapping finger mechanism 41 to improve the strength and stability of the mounting seat 42, thereby improving the stability of the movement of the positive wrapping finger mechanism 41; the positive wrapping finger mechanism 41 is composed of a positive wrapping finger seat and a plurality of positive wrapping fingers. The positive wrapping fingers extend along the length direction of the main shaft 20, and the plurality of positive wrapping fingers are arranged along the circumferential direction of the main shaft 20 and enclose an annular structure. The positive wrapping finger seat is arranged as a circular ring, fixed at one end on the mounting seat 42, and connected to a plurality of positive wrapping fingers at the other end. Optionally, the positive wrapping driving member 43 can adopt a servo motor to improve the positive wrapping accuracy, thereby improving the quality of the tire blank forming.

[0037] As Figure 6 , Figure 7 shown, in this embodiment, the push plate assembly 50 includes a push plate mechanism 51 and a push plate driving member 52. The push plate mechanism 51 is sleeved outside the main shaft 20 at intervals and is movably connected to the mounting seat 42; the push plate driving member 52 is connected to the mounting seat 42 and is drivingly connected to the push plate mechanism 51. The push plate driving member 52 drives the push plate mechanism 51 to move along the axial direction of the main shaft 20. Specifically, the push plate driving member 52 in this embodiment adopts a servo electric cylinder to drive a sprocket group, and the sprocket group drives the lead screw to move axially, and the lead screw drives the push plate mechanism 51 to move axially, so as to improve the accuracy of buckling the bead. Of course, according to actual accuracy requirements, the servo electric cylinder can be replaced by other drives such as an oil cylinder or a cylinder. The push plate mechanism 51 and the positive wrapping finger mechanism 41 are arranged on the same side of the mounting seat 42. The push plate mechanism 51 is arranged between the positive wrapping finger mechanism 41 and the mounting seat 42, and the push plate mechanism 51 is sleeved on the outer peripheral side of the positive wrapping finger seat, and the lead screw can drive the push plate mechanism 51 to move axially.

[0038] In this embodiment, the push plate mechanism 51 includes a snap ring plate 511 and a setscrew mechanism 512. The snap ring plate 511 is sleeved outside the main shaft 20 and is movably connected to the mounting seat 42. The setscrew mechanism 512 passes through the mounting seat 42 and abuts against the snap ring plate 511. When the setscrew mechanism 512 moves relative to the mounting seat 42, it drives the snap ring plate 511 to move radially, so as to change the size of the gap between the inner ring of the snap ring plate 511 and the main shaft 20. Specifically, the snap ring plate 511 of this embodiment is annular, and four setscrew mechanisms 512 are evenly distributed on the circumferential side surface of the snap ring plate 511. The setscrew mechanism 512 includes a setscrew and a setscrew hole. The axial directions of the setscrew and the setscrew hole are both perpendicular to the axial direction of the main shaft 20. The setscrew is located in the setscrew hole and abuts against the outer circumferential side surface of the snap ring plate 511. Therefore, by adjusting the position of the setscrew relative to the setscrew hole, the position of the center of the snap ring plate 511 relative to the center of the main shaft 20 can be adjusted, thereby improving the snap ring accuracy and the forming quality of the tire embryo. Preferably, the setscrew mechanisms 512 are arranged at the four positions of up, down, left and right of the snap ring plate 511 to facilitate the operator to adjust the accuracy of the snap ring plate 511.

[0039] Generally speaking, as Figure 1 shown, the two main shafts 20 on the left and right are fixed on the base 10, Figure 1 and the center is the drum 60 for placing the tire embryo. The drum 60 is supported by the two main shafts 20 on the left and right, so as to realize the rotation and expansion and contraction actions. Capsule assemblies 30, positive wrapping finger assemblies 40, and push plate assemblies 50 are symmetrically arranged on the left and right sides of the drum 60. According to the distance from the drum 60 from near to far, they are the seat body 321 of the capsule assembly 30, the positive wrapping finger mechanism 41, and the push plate mechanism 51. None of the three are directly in contact with the main shaft 20, avoiding jamming with the main shaft 20 during axial movement, and all three are controlled by servo motors. Therefore, the positioning accuracy is high, greatly improving the forming quality of the tire embryo.
