Description

Technical Field

[0001] The present invention relates to the field of tires, and in particular to a rubber tire blank storage device which is convenient for storage and retrieval. Background Art

[0002] The existing Chinese patent publication number is CN216301957U: A non-road tire embryo support device, which can provide good support for the embryo, solve the technical problem that the embryo is easily deformed during storage, and at the same time improve the degree of automation of the embryo support. The cylinder adjusts the lifting height of the upper slide bar to control the rising height of the capsule, which can adapt to a variety of specifications of embryo support.

[0003] However, after the tire blank is formed, it has not been vulcanized and is relatively soft overall. When the bladder is squeezed to the tire bead (also called the bead, which refers to the part of the tire installed on the wheel hub), the soft bead will undergo some plastic deformation under the squeezing of the bladder. After long-term storage, the deformation of the bead cannot be restored, resulting in inaccurate tire size during subsequent vulcanization molding, which greatly affects the tire molding quality.

Then, the external pump is controlled to start and coolant is delivered to the rubber tube, so that the rubber tube cools the tire bead of the tire body, so that the tire bead is relatively hardened at low temperature, the softness of the tire bead is reduced, and excessive plastic deformation of the tire bead is avoided when the elastic cloth supports the tire bead for a long time.

[0016] The present invention controls the push rod to drive the push plate to move toward the inner side of the tire embryo body until the push plate contacts the inner side of the tire embryo body, thereby supporting the inner side of the tire embryo body. When the push plate moves, it drives the sliding plate and the support rod to move, and the sliding plate and the support rod move close to the inner side of the tire embryo body, so that the sliding plate and the support rod slide downward in the slide groove under the limitation of the tire embryo body and compress the spring rod, so that the sliding plate and the support rod support the inner upper part of the tire embryo body under the elastic force of the spring rod, thereby keeping the inner side of the tire embryo body in a vertical state.

[0017] The present invention limits the position of the tire body by a limiting ring so that the center of the tire body coincides with the center of the tray, and the tire body is manually placed on the limiting ring. After the tire body contacts the support plate, the sponge material support plate adaptively deforms to support the lower side of the tire body, preventing the lower side of the tire body from directly contacting the tray and deforming.

The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] Example 1

[0029] A rubber tire storage device that is easy to access, such as Figure 1-8 As shown, it includes a storage rack 1;

[0030] It also includes a support plate 2, a tray 3, a fixing rod 101, a fixing disk 102, an airbag ring 103, an elastic cloth 104, a rubber tube 105, a fixing ring 106 and a connecting tube 107; the storage rack 1 is connected to a number of vertically distributed plate groups; each plate group is composed of four rectangularly distributed support plates 2, the storage rack 1 is rotatably connected to all the support plates 2 by a torsion spring, and the support plate 2 can only be turned ninety degrees on the storage rack 1, from a vertical state to a horizontal state; a tray 3 for supporting the tire blank body 6 is placed on each of the same plate groups; a circular notch is opened in the middle of the tray 3, and the diameter of the notch is larger than the diameter of the airbag ring 103 in the initial state; the storage rack 1 is fixed with a fixing rod 1 01; the fixed rod 101 is fixed with several vertically distributed disc groups, and the number of disc groups corresponds to the number of trays 3; each disc group is composed of two symmetrically distributed fixed discs 102; each fixed disc 102 is fixed with a fixed ring 106; each fixed ring 106 is fixed with an airbag ring 103; each airbag ring 103 is fixed with the bottom of a stretch cloth 104, and the top of the stretch cloth 104 is fixed with the fixed rod 101; each elastic cloth 104 is fixed with a rubber tube 105 on the inner side, and the rubber tube 105 is in contact with the airbag ring 103; each fixed ring 106 is fixed with a connecting tube 107, and the connecting tube 107 is connected to the airbag ring 103.

[0031] It also includes a connecting plate 4, a connecting bucket 5, a connecting rod 21 and a rope 22; each pallet 3 is fixedly connected to two symmetrically distributed connecting plates 4; each pallet 3 is fixedly connected to two symmetrically distributed connecting buckets 5, and the connecting buckets 5 are located below the connecting plates 4, and the connecting buckets 5 and the connecting plates 4 cooperate with each other; the two upper and lower adjacent support plates 2 are commonly connected to a rope 22; the storage rack 1 is fixedly connected to a number of connecting rods 21, and the front and rear adjacent ropes 22 are slidably connected to the corresponding connecting rods 21; the initial state of the support plate 2 in the lowest plate group is inclined, and the other plate groups are vertical, and the rope 22 between the lowest support plate 2 and the second support plate 2 from the bottom to the top is in a taut state at this time.

[0032] The elastic fabric 104 is arranged in a conical shape, thereby increasing the contact area between the elastic fabric 104 and the tire blank body 6 and improving the supporting effect.

[0033] The surface of the stretch fabric 104 is smooth.

[0034] During use, the external pump is first connected to the rubber tube 105, and the external air pump is connected to the connecting pipe 107. After the tire blank body 6 is formed, the tire blank body 6 is manually placed horizontally on the pallet 3. Then, the fork arm of the external palletizer is manually controlled to support the lower side of the pallet 3, and the pallet 3 supporting the tire blank body 6 is placed on the support plate 2 from top to bottom. During this process, the tire blank body 6 and the pallet 3 pass through the fixing rod 101, the fixing plate 102 and the components connected thereto;

[0035] Since the tire blank body 6 produced is single, the fork arm can only place one tire blank body 6 and tray 3 through the fixing rod 101 onto the storage rack 1 at a time. The following description is from bottom to top.

[0036] When the first tire blank body 6 and the tray 3 pass through the fixing rod 101 and reach the lowest support plate 2, the lowest support plate 2 is initially in an inclined state under the action of the torsion spring, while the remaining support plates 2 are in a vertical state. Figure 8 As shown, after the tray 3 contacts the lowermost support plate 2, the lowermost support plate 2 rotates downward under the pressure of the tray 3 and gradually becomes horizontal. The torsion spring connected to the lowermost support plate 2 is compressed, so that the lowermost support plate 2 supports the tire embryo body 6 and the tray 3. The lowermost support plate 2 pulls the rope 22 connected to its upper surface while rotating downward. The rope 22 is straightened under the limiting action of the connecting rod 21, and then the rope 22 pulls the upper support plate 2 into an inclined state. The upper support plate 2 pulls the rope 22 that was originally in a relaxed state, and then when the second tire embryo body 6 and the tray 3 reach the second support plate 2, due to the The two support plates 2 are in an inclined state, so that the second support plate 2 rotates downward to a horizontal state under the pressure of the tray 3, thereby supporting the second tire blank body 6 and the tray 3. At the same time, the second support plate 2 pulls the rope 22 connected to its upper surface while rotating downward, thereby making the third support plate 2 inclined, and so on, until the storage rack 1 is full of tire blank bodies 6; it should be noted that, when the second support plate 2 rotates downward under the pressure of the tray 3 it carries, the rope 22 between the second support plate 2 and the first support plate 2 changes from a taut state to a loose state, so as to avoid the rope 22 being taut for a long time and affecting its service life.

[0037] When the tire blank body 6 needs to be taken out for vulcanization, the fork arm of the external palletizer is manually controlled to support the lower side of the top tray 3 of the storage rack 1, driving the tray 3 supporting the tire blank body 6 to move upward, thereby taking the tray 3 supporting the tire blank body 6 out of the storage rack 1. When it is necessary to take out multiple tire blank bodies 6 at the same time, the fork arm of the external palletizer is manually controlled to support the lower side of the bottom tray 3 of the storage rack 1, driving the bottom tray 3 and the components connected thereto to move upward, so that the connecting plate 4 on the bottom tray 3 is inserted into the connecting bucket 5 of the upper tray 3, and the upward moving tray 3 pushes the supporting plate 2, causing the supporting plate 2 to rotate upward under the action of the torsion spring, and so on, thereby all the trays 3 on the storage rack 1 are connected into a whole through the connecting plate 4 and the connecting bucket 5, so that the fork arm of the external palletizer drives the bottom tray 3 and the components connected thereto to move upward, and at the same time, all the trays 3 supporting the tire blank bodies 6 on the storage rack 1 are taken out of the storage rack 1 together, thereby realizing the function of easy access.

[0038] After the tire body 6 and the tray 3 pass through the fixing rod 101 and the fixing plate 102 and the parts connected thereto and are placed on the support plate 2, the external air pump is controlled to start and the airbag ring 103 is inflated through the connecting pipe 107. The inner side of the airbag ring 103 is fixed by the fixing ring 106, so that the outer side of the airbag ring 103 expands outward, and the outer side of the airbag ring 103 drives the elastic fabric 104 to stretch outward under the action of its own elastic force. After the elastic fabric 104 contacts the tire bead 6a of the tire body 6, the elastic fabric 104 continues to stretch outward under the expansion of the airbag ring 103. After the elastic fabric 104 contacts the tire bead 6a, relative movement occurs until the elastic fabric 104 pushes the tire bead 6a. The elastic fabric 104 is lifted up, thereby supporting the bead 6a of the tire blank body 6. Since the surface of the elastic fabric 104 is smooth, the friction between the elastic fabric 104 and the bead 6a is reduced during the relative movement after the elastic fabric 104 and the bead 6a come into contact, thereby avoiding the elastic fabric 104 causing wear on the bead 6a. Then, the external pump is controlled to start and the coolant is delivered to the rubber tube 105, so that the rubber tube 105 cools the bead 6a of the tire blank body 6, making the bead 6a relatively hardened at low temperature, reducing the softness of the bead 6a, and thereby avoiding excessive plastic deformation of the bead 6a when the elastic fabric 104 supports the bead 6a for a long time.

[0039] Example 2

[0040] On the basis of Example 1, Figure 2-7 As shown, it also includes a spreading assembly; the spreading assembly includes a push rod 201 and a push plate 202; the fixed rod 101 is bolted to a plurality of vertically distributed rod groups, and each rod group is located in a corresponding disk group; each rod group is composed of three annularly distributed push rods 201; the telescopic end of each push rod 201 is fixed with an arc-shaped push plate 202.

[0041] The expansion assembly also includes a spring rod 203, a sliding plate 204, and a support rod 205; each push plate 202 is provided with a sliding groove 202a; each sliding groove 202a is fixed with a number of spring rods 203; the telescopic ends of all spring rods 203 located in the same sliding groove 202a are fixed with a sliding plate 204, and the sliding plates 204 slide in the corresponding sliding groove 202a; each sliding plate 204 is fixed with a support rod 205.

[0042] The expansion assembly also includes a support cloth 206 and a connecting ring 207; each airbag ring 103 is fixed with a support cloth 206 made of elastic material on the outside; each support cloth 206 is fixed with a connecting ring 207, and the connecting ring 207 cooperates with the support rod 205.

[0043] The upper and lower sides of the push plate 202 are both rounded to reduce the wear of the push plate 202 on the tire blank body 6.

[0044] After the elastic fabric 104 supports the bead 6a of the tire embryo body 6, in order to prevent the soft tire embryo body 6 from being deformed after being placed horizontally for a long time after being placed on the tray 3, the control push rod 201 drives the push plate 202 to move in the direction close to the inner side of the tire embryo body 6 until the push plate 202 contacts the inner side of the tire embryo body 6, thereby supporting the inner side of the tire embryo body 6. When the push plate 202 moves, it drives the sliding plate 204 and the support rod 205 to move, and the sliding plate 204 and the support rod 205 are tightly attached to the inner side of the tire embryo body 6, so that the sliding plate 204 and the support rod 205 slide downward in the slide groove 202a under the limitation of the tire embryo body 6 and compress the spring rod 203, so that the sliding plate 204 and the support rod 205 support the inner upper part of the tire embryo body 6 under the elastic force of the spring rod 203, thereby keeping the inner side of the tire embryo body 6 in a vertical state.

[0045] When the sliding plate 204 and the support rod 205 move toward the inner side of the tire body 6, the support rod 205 contacts the connecting ring 207, and the connecting ring 207 is stuck on the lower side of the annular support rod 205, so that the support rod 205 drives the connecting ring 207 to move toward the inner side of the tire body 6. The connecting ring 207 stretches the support cloth 206, and the elastic material support cloth 206 undergoes adaptive deformation under the action of its own elastic force, so that the support cloth 206 supports the inner side of the tire body 6. Figure 7 As shown, it is possible to prevent the inner side of the tire blank body 6 from falling and deforming under the action of its own gravity when it is placed horizontally for a long time.

[0046] Example 3

[0047] On the basis of Example 2, Figure 3-4 As shown, it also includes a limiting component; the limiting component includes a limiting ring 301; each tray 3 is fixed with a limiting ring 301.

[0048] The limiting assembly further includes a supporting plate 302 ; a supporting plate 302 made of sponge material is fixedly connected to the inner side of each limiting ring 301 .

[0049] When the embryo body 6 is manually placed on the tray 3, there is an offset between the center of the embryo body 6 and the center of the tray 3, which makes the support force of the elastic cloth 104 and multiple push plates 202 on the embryo body 6 uneven, thereby affecting the support effect of the elastic cloth 104 and the push plates 202 on the embryo body 6. At this time, the embryo body 6 is manually placed in the limiting ring 301, and the position of the embryo body 6 is limited by the limiting ring 301 so that the center of the embryo body 6 coincides with the center of the tray 3, and the embryo body 6 is manually placed on the limiting ring 301. After the embryo body 6 contacts the support plate 302, the sponge material support plate 302 undergoes adaptive deformation to support the lower side of the embryo body 6, preventing the lower side of the embryo body 6 from directly contacting the tray 3 and deforming.

[0050] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to be illustrative only and not to limit the present invention, which is to be defined by the claims.
