Description

Technical Field

[0001] The utility model belongs to the technical field of tire manufacturing, and in particular relates to a multi-station tire embryo storage, centering and shaping device. Background Art

[0002] The last step in tire production is to vulcanize the tire embryo at high temperature. When the tire embryo is vulcanized, the tire storage tray is located below the vulcanizer manipulator, and the vulcanizer tire claw grabs the tire embryo and sends it to the vulcanization model center for vulcanization. Since the tire embryo will collapse and deform during storage and transportation, the tire embryo will be tilted and eccentric when the vulcanizer tire claw grabs the tire embryo and sends it to the vulcanization model center. The collapse and deformation of the tire embryo will cause the tire embryo to fit poorly with the mold, resulting in defects in the tire after vulcanization or quality problems such as unsatisfactory dynamic balance. At present, the method adopted is: after the vulcanizer tire claw grabs the tire embryo and sends it to the vulcanization model center, workers are required to stretch and shape the collapsed and deformed tire embryo, which is time-consuming and labor-intensive, has low production efficiency, and the shaping effect is not good.

[0003] Chinese patent CN219381707U discloses a centering stretching and shaping device for a tire embryo. Although the clamping claws are used to shape the embryo, the shaping device can only shape one tire embryo at a time, and the production efficiency is low. Utility Model Content

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "up", "down", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figure 1-Figure 3 As shown, a multi-station embryo storage and centering shaping device is characterized in that the multi-station embryo storage and centering shaping device comprises: a rotating frame 1, at least two clamping claws, and a displacement adjustment structure, wherein:

[0039] The rotating frame 1 is rotatably arranged and has at least two placement frames with lower opening structures for storing embryos distributed around the rotation axis of the rotating frame 1. For example, in this embodiment, the hollow space formed between the first frame body 11 and the second frame body 12 is the placement frame. Further, the rotation of the rotating frame 1 can be connected to the rotating shaft 15 through the output end of the rotating driving machine 7 as in this embodiment, and the rotating shaft 15 drives the rotating frame 1 to rotate.

[0040] At least two claws 4 are arranged below the motion path of the placement rack, and the claws 4 move by displacement to clamp and position the embryo; it can be understood that the two claws 4 extend outward at the same time to stretch and shape the embryo located on the two claws 4. Further, the rotating cylinder 5 in this embodiment can be connected to the claws 4 to drive the claws 4 to extend outward.

[0041] The displacement adjustment structure is used to drive the relative or opposite movement between the rotating frame 1 and the clamping claw 4, so that the clamping claw 4 extends to or escapes from the lower ring opening of the embryo through the lower opening structure of the placing frame 1. It can be understood that when the rotating frame 1 rotates, a certain distance is kept between the tire blank and the clamping claw 4 so that the rotating frame 1 rotates smoothly. When the clamping claw 4 shapes the tire blank, the rotating frame 1 needs to be lowered or the clamping claw needs to be raised so that the clamping claw can support the tire blank.

[0042] Furthermore, the rotating frame 1 rotates, driving multiple tire blanks to rotate. When the tire blank to be shaped is located above the claws, the displacement adjustment structure is activated, the claws enter the tire blank, and the claws extend to shape the tire blank. After the tire blank is shaped, the displacement adjustment structure is activated, the rotating frame 1 or the claws 4 return to their positions, and the rotating frame continues to rotate, driving the tire blank on the next placement rack to be shaped in correspondence with the claws.

[0043] In this embodiment, a plurality of green tires are placed on the rotating frame, and the clamping claws shape the plurality of green tires in sequence, thereby improving production efficiency.

[0044] like Figure 1As shown, in other embodiments, it also includes:

[0045] A plurality of tire storage mechanisms 3 are respectively fixed on the placement rack, and a hollow space is provided inside the tire storage mechanism 3, and the cross section of the hollow space is consistent with the shape of the tire blank. It can be understood that when the tire blank is placed in the tire storage mechanism, the tire storage mechanism fixes the tire blank because the cross section is consistent with the shape of the tire blank, and when the claws shape the tire blank, the tire blank is more stable and the shaping effect is better.

[0046] like Figure 1 As shown, in other embodiments, a plurality of tire storage mechanisms 3 are composed of concentric circles of different diameters. It is understandable that, since the outer diameter of the tire has various specifications, the diameter of the cross section may be adjusted according to the tire specifications. When the diameter of the tire blank to be shaped is large, the tire storage structure 3 increases the upper opening concentric circle to increase the diameter of the upper opening cross section. This embodiment can make the tire storage mechanism 3 adapt to tire blanks of different specifications.

[0047] like Figure 3 As shown, in other embodiments, the rotating frame 1 further comprises:

[0048] Multiple frames, such as the first frame 11, the second frame 12, and the third frame 13 in this embodiment, are radially connected to the rotating axis, and a placement rack is formed between two of the frames. It can be understood that the frame structure is simple and easy to manufacture.

[0049] like Figure 2 As shown, in other embodiments, it also includes: a frame 2 connected to the bottom of the rotating frame 1. It can be understood that the rotating frame 1 is fixed on the frame to make the rotating frame 1 more stable when rotating. The frame 2 includes:

[0050] The base 21 is a frame structure; the circular rail 22 fixes the upper end of the base 21 .

[0051] like Figure 2 As shown, in other embodiments, it also includes: multiple bottom plates 23, multiple bottom plates are fixed on both sides of the base, and multiple bottom plates are respectively fixed to the ground using fasteners, such as the pins 24 and pin sleeves 25 in this embodiment, so as to make the frame structure more stable.

[0052] like Figure 2 As shown, in other embodiments, the rotating frame 1 further includes:

[0053] The ball bearings 14 are located below the rotating frame 1, and the ball bearings 14 drive the rotating frame 1 to rotate on the circular rail 22. The embodiment realizes the rotation of the rotating frame 1 on the frame 2.

[0054] like Figure 4 As shown, in other embodiments, the displacement adjustment structure is:

[0055] The lifting drive 6 is connected to the claw 4 or the rotating frame 1 to drive the claw 4 / rotating frame 1 to rise or fall. As in the present embodiment, the lifting drive 6 is connected to the claw 4 to drive the claw 4 to rise or fall. In other embodiments, it can also be connected to the rotating frame 1 and installed below the rotating frame 1. When the rotating frame 1 rotates, the lifting drive 6 drives the rotating frame 1 to rise. When the claw 4 shapes the tire blank, the lifting drive 6 drives the rotating frame 1 to fall.

[0056] like Figure 2 As shown, in other embodiments, the circular track is 3 / 4 circle, and the claw 4 is located on the long arc of the circular track. It can be understood that the rotation range of the rotating frame 1 is 3 / 4 arc, and the claw 4 is located on the other 1 / 4 arc, which can avoid interference between the rotating frame 1 and the claw 4, and the structure is more compact.

[0057] like Figure 3 As shown, in other embodiments, the number of the racks is 3, such as the first rack 11, the second rack 12, and the third rack 13 in this embodiment, the angle between the two racks is 120°, and the number of the placement racks is 3. It can be understood that the three racks are evenly distributed, making it more stable during the rotation process; the three placement racks make full use of the space to place more tire blanks.

[0058] like Figure 1 As shown, in other embodiments, the tire storage mechanism 3 is made of metal material, and the surface is plated with hard chrome. The hard chrome can prevent the tire from sticking and is more conducive to taking the tire.

[0059] like Figure 5 As shown, in other embodiments, the number of the claws 4 is 4. The 4 claws are simultaneously outward to prop up the tire blank, so that the tire blank is more easily propped up and the shaping effect is better.

[0060] Through the description of multiple embodiments of the multi-station embryo storage and centering shaping device of the utility model, it can be seen that the utility model has at least the following advantages:

[0061] In the utility model, a plurality of tire blanks to be shaped are placed on a plurality of rotating racks, and when the rotating racks rotate, the plurality of tire blanks are shaped in sequence corresponding to the clamping claws, thereby improving production efficiency;

[0062] The rotating frame of the utility model rotates on the 3 / 4 circular rail, and the clamping claws are located on the connecting line of the 3 / 4 circular rail, so the structure is more compact.

[0063] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0064] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
