Description

[Technical field]

[0001] The utility model belongs to the technical field of tire manufacturing, and in particular relates to a tire storage device. [Background technology]

[0002] The storage of tire blanks in the semi-steel tire vulcanizer consists of a tire storage device and a tire grabber. The tire storage device is the first step in the vulcanizer to load tires. The stability of the tire storage device is not only related to the effect of grabbing the tire, but also indirectly affects the loading and vulcanization effects. The newly installed tire storage device has the advantages of high equipment precision, less wear, and accurate positioning. The tire blanks are smoothly grabbed during the transfer from the tire storage device to the tire grabber (the probability of the tire blank tilting after grabbing is low), and the tire blanks are accurately positioned after grabbing. When the tire blanks are loaded on the vulcanizer, they can also be smoothly sent to the steamer according to the set position. After the equipment has been used for a period of time, due to partial wear of the equipment, the tire storage device will cause positioning deviations during the tire hanging process, but it can still operate, but the positioning is not accurate enough. Improper operation of this process is prone to produce NB / PB defective products, which poses a major quality risk.

[0003] At present, the solution to this problem is to replace the device that has inaccurate tire positioning and more deflection of tire hanging, and adjust the positioning length of the original device. The second is to manually adjust the tire grabber and straighten the tire embryo after the tire is grabbed. However, there are two disadvantages in doing so: first, the tire grabber and tire storage device must be replaced or adjusted frequently, which increases the labor intensity of the security personnel and the maintenance cost of the equipment. Second, when manually straightening the tire embryo, more people are involved in the production process, and the degree of understanding of the tire embryo hanging standard is different. In addition, the production efficiency of semi-steel tires is much greater than that of full-steel tires, so the number of defective semi-steel tires will increase significantly. [Utility Model Content]

[0004] The utility model aims to provide a tire storage device to solve the problems of low precision and low working efficiency in that the tire embryo needs to be manually straightened after the existing tire grabbing is completed.

[0005] The utility model adopts the following technical scheme: the tire storage device comprises:

[0006] A cylinder, the central axis of the cylinder extending upward;

[0007] A sleeve, the sleeve is coaxially sleeved outside the central axis, a connecting rod seat is coaxially fixedly installed outside the top of the sleeve, a spring seat is coaxially slidably installed outside the bottom of the sleeve, the spring seat is fixedly connected to a spring extending upward, and the spring is coaxially sleeved on the outer wall of the sleeve;

[0008] At least two tire retaining claws are evenly arranged around the top of the central axis; each tire retaining claw is a vertically arranged flat plate, the upper section of the flat plate, the side away from the central axis, protrudes outward to form an upper step, and the bottom of the upper step to the bottom end of the flat plate is a smoothly transitional inclined surface;

[0009] At least two adjusting rods, one end of each adjusting rod is fixedly connected to the top end of the central shaft, and the other end of each adjusting rod is hinged to each tire storage claw;

[0010] At least two second connecting rods, one end of each second connecting rod is hinged to the lower part of the tire retaining claw, and the other end is hinged to the bottom of the spring;

[0011] At least two first connecting rods, one end of each first connecting rod is hinged to each adjusting rod, and the other end of each first connecting rod is hinged to the connecting rod seat;

[0012] The central axis is used to push up or reset downward under the push of the cylinder, and under the rotation drive of the paired adjusting rods and the first connecting rod, each tire storage claw is retracted inward or spread outward for storing or removing the tire.

[0013] Furthermore, each adjusting rod has the same structure, and one adjusting rod has a long slide groove and a long connecting rod arranged in the same direction; one end of the connecting rod is hinged to the tire storage claw; one end of the slide groove close to the tire storage claw is hinged to the first connecting rod, and the other end is fixed to the top end of the central shaft;

[0014] The connecting rod is used for reciprocating movement in the slide groove to adjust the relative distance between each tire retaining claw.

[0015] Furthermore, the number of the tire retaining claws, the adjusting rod, the first connecting rod and the second connecting rod are all four.

[0016] The beneficial effects of the utility model are as follows: the outer side surface of the tire storage claw of the utility model has an upper step, and the tire bead on the tire embryo can be fixed by the support of the top surface of the upper step; when the tire embryo is lifted by the tire grabber, the bottom surface of the upper step will exert downward pressure on the tire, so that the tire embryo is dragged out along the direction of the positioning disk, and the tire embryo is automatically straightened; by adjusting the length of the adjustment rod, the relative position of each tire storage claw can be adjusted to match the storage of tires of various sizes. Through the tire storage device of the utility model, the operator only needs to place the tire on the tire storage device to realize the automatic tire grabbing and potting function, which improves the operating efficiency, reduces the labor intensity of workers, saves equipment maintenance costs, and reduces the probability of defective tire embryos.

[Specific implementation method]

[0021] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0022] The utility model provides a tire storage device, such as Figures 1 to 3 As shown, it includes a cylinder 10, a central shaft 5, a sleeve 9 and a tire retaining claw 1, as well as an adjusting rod 2, a first connecting rod 3 and a second connecting rod 4.

[0023] The cylinder 10 is located at the bottom, and the central axis 5 of the cylinder 10 extends upward. The sleeve 9 is coaxially sleeved outside the central axis 5, and a connecting rod seat 6 is coaxially fixedly installed outside the top of the sleeve 9, and a spring seat 8 is coaxially slidably installed outside the bottom of the sleeve 9. The spring seat 8 is fixedly connected to a spring 7 extending upward, and the spring 7 is coaxially sleeved on the outer wall of the sleeve 9. The spring seat 8 can slide up and down along the outer wall of the sleeve 9, and the spring 7 is compressed by sliding upward, and the spring 7 is reset downward to make the spring seat slide downward.

[0024] At least two tire retaining claws 1 are evenly arranged around the top of the central axis 5; each tire retaining claw 1 is a vertically arranged flat plate, the upper section of the flat plate, the side away from the central axis 5, protrudes outward to form an upper step 11, and a smooth transition slope 12 is formed between the bottom of the upper step 11 and the bottom of the flat plate. The functions of the upper step 11 are: first, after the tire is put in, the upper bead of the tire is supported by the top surface of the upper step 11; second, when the tire is taken out, a certain amount of obstruction is generated to the removal action, that is, the lower part of the upper step 11 will block the removal of the lower bead of the tire, and then in the process of overcoming the obstruction and continuing to take out the tire, the position of the tire will be automatically corrected.

[0025] At least two adjusting rods 2, one end of each adjusting rod 2 is fixedly connected to the top of the central shaft 5, and the other end of each adjusting rod 2 is hinged to each tire retaining claw 1. At least two second connecting rods 4, one end of each second connecting rod 4 is hinged to the lower part of the tire retaining claw 1, and the other end is hinged to the bottom of the spring 7. At least two first connecting rods 3, one end of each first connecting rod 3 is hinged to each adjusting rod 2, and the other end of each first connecting rod 3 is hinged to the connecting rod seat 6.

[0026] The central shaft 5 is used to push up or reset downward under the push of the cylinder 10, and driven by the rotation of the paired adjusting rods 2 and the first connecting rod 3, each tire storage claw 1 is retracted inward or expanded outward. When retracted, it can be used to put in a tire and perform a tire storage action; when expanded, it can support the tire.

[0027] The upper tire bead is located above the inner side of the tire, and the lower tire bead is located below the inner side. Each tire retaining claw 1 is used to support the inner side of the upper tire bead through its top in the outwardly expanded state to achieve tire retention. It is also used to block the lifting action of the lower tire bead through the upper step 11 when the tire is lifted upward, and compress the spring 7 through the lifting spring seat 8. Continuing to lift upward will cause the tire to detach from the tire retaining claw 1; the spring 7 is used to drive the spring seat 8 to reset.

[0028] In some embodiments, each of the adjustment rods 2 has the same structure, and one of the adjustment rods 2 has a long strip-type slide 21 and a long strip-type connecting rod 22 arranged in the same direction; one end of the connecting rod 22 is hinged to the tire retaining claw 1; one end of the slide 21 close to the tire retaining claw 1 is hinged to the first connecting rod 3, and the other end is fixed to the top of the central axis 5; the connecting rod 22 is used to reciprocate in the slide 21 to adjust the relative distance of each tire retaining claw 1. The relative position of the slide and the connecting rod can be fixed by bolts, and adjusting the relative position of the slide and the connecting rod is to adjust the relative position of each tire retaining claw, so that the tire retainer is suitable for the placement of tires of different diameters.

[0029] In some embodiments, the number of the tire retaining claw 1, the adjusting rod 2, the first connecting rod 3 and the second connecting rod 4 are all four.

[0030] A method for using a tire storage device of the utility model is as follows:

[0031] 1. The cylinder 10 pushes the central shaft 5 upward, thereby driving each tire retaining claw 1 to close, and then put the tire in. The cylinder 10 then drives the central shaft 5 downward, so that each tire retaining claw 1 is spread open, and the upper tread of each tire retaining claw 1 supports the upper bead of the tire.

[0032] 2. The tire is grabbed upward by the tire grabber. In the first stage, the lower tire bead is stuck on the bottom surface of the upper step 11 and stops briefly. Then the tire grabber continues to grab the tire upward. During this process, the position of the tire will be automatically corrected. At the same time, each tire retaining claw 1 is squeezed, moves upward and closes, and the spring 7 is compressed, finally causing the tire to detach from the tire retainer.

[0033] 3. After the tire is detached, the spring 7 is reset and drives the spring seat to move down and reset, and each tire retaining claw 1 is opened to the original state.

[0034] The outer side of the tire storage claw of the utility model has an upper step, and the tire bead on the tire embryo can be fixed by the support of the top surface of the upper step; when the tire embryo is lifted by the tire grabber, the bottom surface of the upper step will exert downward pressure on the tire, so that the tire embryo is dragged out along the direction of the positioning disk, and the tire embryo is automatically straightened; by adjusting the length of the adjustment rod, the relative position of each tire storage claw can be adjusted to match the storage of tires of various sizes. Through the tire storage device of the utility model, the operator only needs to place the tire on the tire storage device to realize the automatic tire grabbing and potting function, which improves the operating efficiency, reduces the labor intensity of workers, saves equipment maintenance costs, and reduces the probability of defective tire embryos.
