Description

Technical Field

[0001] The invention belongs to the field of tire manufacturing, and in particular relates to a cloth wrapping machine and a cloth wrapping method. Background Art

[0002] In the production of tires and wires, the rubber compound needs to be wrapped layer by layer on the steel rim during the wrapping process. In the wrapping of the steel rim, the wrapping method currently used, such as the new tire forming wrapping machine with patent number CN201420669886.4, rotates the wrapping rod upward to support the capsule, and the capsule wraps the rubber compound on the steel rim. In this way, both sides of the steel rim are squeezed at the same time. If the force on both sides is uneven, the steel rim will move, and the side root at the bottom of the steel rim on one side will not fit tightly, forming an air hole, making it difficult to fit completely. Summary of the Invention

[0003] In order to solve the defects mentioned in the background technology, the present invention presents a cloth wrapping machine and a cloth wrapping method.

[0004] In order to achieve the above objectives, the following technical solutions are provided:

[0005] A cloth wrapping machine comprises a vertical plate mechanism, a capsule reverse wrapping mechanism, a capsule push plate mechanism and a root rolling mechanism;

[0006] The vertical plate mechanism, the capsule reverse packaging mechanism and the capsule push plate mechanism are sequentially arranged at one end of the main shaft, a locking block mechanism is arranged between the vertical plate mechanism and the capsule reverse packaging mechanism, and the root rolling mechanism is arranged on the upper part of the locking block mechanism;

[0007] The other end of the main shaft is arranged in the box body, and a bearing is arranged between the box body. A synchronous wheel is arranged in the middle of the main shaft, and a synchronous belt connects the synchronous wheel and the motor.

[0008] Furthermore, the vertical plate mechanism includes a cylinder 1, which is a hollow cylinder sleeved on the main shaft, and the cylinder rod of the cylinder 1 is hingedly connected to the vertical plate through a connecting rod 1.

[0009] Furthermore, the locking block mechanism includes cylinder 2 and locking block 1. Cylinder 2 is a hollow cylinder, which is sleeved on the main shaft. The extending rod of cylinder 2 is hinged to locking block 1 through connecting rod 2. A limiting ring is provided on one side of the locking block, and the vertical plate is hinged to locking block 1.

[0010] Furthermore, the capsule reverse packaging mechanism includes a capsule and a locking block 2, the capsule is fixed on the locking block 1 and the locking block 2, and an airway is provided on the lower side of the locking block 2.

[0012] Furthermore, the root rolling mechanism includes a pressing roller cylinder and a pressing roller, and the pressing roller is fixedly arranged on the telescopic rod of the pressing roller cylinder.

[0013] A cloth wrapping method includes the following steps: 1. placing the rubber material and the steel ring at a set position;

[0014] Step 2: Raise the locking block and press the rubber material against the underside of the steel ring;

[0015] Step 3: Rotate the vertical plate to stick the rubber material to one side of the steel ring;

[0016] Step 4: Inflate the capsule to lift the rubber material, and the rubber material is attached to the other side of the steel ring;

[0017] Step 5: Use the push plate to push the capsule to stick the rubber material to the other side of the steel ring;

[0020] Furthermore, in the step three, the cylinder 1 actively moves, driving the connecting rod 1 to rotate, thereby driving the vertical plate to rotate; in the step four, the air flow enters the capsule from the airway, inflating the airbag.

[0021] Furthermore, in step six, the pressure roller cylinder drives the pressure roller to extend toward the steel ring, and the main shaft rotates to press the rubber material onto the steel ring along the root of the steel ring.

[0022] Beneficial effects of the present invention:

[0023] The present invention provides a wrapping machine that wraps the cloth on one side of a steel rim using a vertical plate mechanism. A bladder is inflated and wrapped on the other side of the steel rim. The bladder is pushed by a push plate mechanism, pressing the bladder against the upper portion of the rubber compound.

[0024] The present invention provides a cloth wrapping machine. A locking block first adheres the rubber material to the bottom of a steel ring. Then, a vertical plate rotates to fold and adhere the rubber material on one side of the steel ring. After the bottom is adhered, the locking block is used to limit the movement of the steel ring. The vertical plate lifts the rubber material on one side. A bladder on the other side is inflated to lift the rubber material. Then, a push plate pushes the bladder to press the rubber material against the steel ring. These two sides are adhered separately, and one side is a vertical plate. This can prevent the bottom two sides of the steel ring from being loosely adhered. A pressure roller rolls the rubber material on the upper part of the steel ring to solve the problem of loose adhesion on the upper part of the steel ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make those skilled in the art more clear and specific about the technical solution of the present invention, the technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0031] like Figure 1 As shown, a cloth wrapping machine includes a vertical plate mechanism 3, a capsule reverse wrapping mechanism 5, a capsule push plate mechanism 6 and a root rolling mechanism 7;

[0032] The vertical plate mechanism 3, the capsule reverse packaging mechanism 5 and the capsule push plate mechanism 6 are sequentially arranged at one end of the main shaft 2. A locking block mechanism 4 is arranged between the vertical plate mechanism 3 and the capsule reverse packaging mechanism 5. The root rolling mechanism 7 is arranged on the upper part of the locking block mechanism 4.

[0033] The other end of the main shaft 2 is disposed within the housing 1, with a bearing 21 disposed therebetween. A synchronous pulley is disposed in the middle of the main shaft 2, and a synchronous belt connects the synchronous pulley to the motor. By rotating the main shaft 2, the steel ring and the rubber compound 91 rotate, and the root rolling mechanism 7 completes the rolling of the steel ring.

[0034] The vertical plate mechanism 3 includes a cylinder 31, which is a hollow cylinder and sleeved onto the main shaft 2. The cylinder rod of cylinder 31 is hingedly connected to the vertical plate 33 via a connecting rod 32. The vertical plate 33 surrounds the main shaft 2, and the connecting rod 32 also surrounds the main shaft 2. The cylinder pushes the vertical plate 33 upward through the connecting rod 32, completing the rubber material 91 wrapping on one side of the steel ring.

[0035] The locking block mechanism 4 comprises a second cylinder 41 and a first locking block 43. The second cylinder 41 is a hollow cylinder that fits over the main shaft 2. The extension rod of the second cylinder 41 is hingedly connected to the first locking block 43 via a second connecting rod 42. A limit ring is provided on the side of the first locking block 43. The vertical plate 33 is hingedly connected to the first locking block 43. When the second cylinder 41 is actuated, the second connecting rod 42 pushes the first locking block 43 upward, causing the rubber material 91 on the bottom of the steel ring to adhere to the steel ring.

[0036] The capsule reverse packing mechanism 5 includes a capsule 51 and a second locking block 52. The capsule 51 is fixed to the first locking block 43 and the second locking block 52. An air channel 53 is provided on the lower side of the second locking block 52. The first locking block 43 and the second locking block 52 are used to fix the capsule 51. Air flows through the air channel 53 to inflate the capsule 51, causing the capsule 51 to swell and press the rubber material 91 toward one side of the steel ring.

[0037] The capsule push plate mechanism 6 includes a push plate 61 and a third cylinder 62. Three push plates 61 and three cylinders 62 are arranged around the main shaft 2. The push plate 61 is fixed to the rod of the third cylinder 62 and is located on one side of the capsule 51. When the third cylinder 62 is actuated, it pushes the push plate 61 against the capsule 51, which in turn presses the rubber material 91 toward the upper portion of the steel ring.

[0038] The root rolling mechanism 7 includes a pressing roller cylinder 71 and a pressing roller 72 , and the pressing roller 72 is fixedly arranged on the telescopic rod of the pressing roller cylinder 71 .

[0039] One side of the steel ring is wrapped with cloth using a vertical plate mechanism 3, and the other side of the steel ring is wrapped with cloth after the capsule 51 is inflated, and the capsule 51 is pushed by the push plate 61 mechanism, so that the capsule 51 presses the upper part of the rubber material 91. The upper side of the steel ring pushes the capsule 51 through the push plate 61, so that the capsule 51 presses the rubber material 91 concave toward the upper part of the steel ring, and finally the root rolling mechanism 7 rolls the rubber material 91 so that it is completely attached to the upper part of the steel ring.

[0040] The steps are as follows: Figure 2Principle diagram, step 1, the rubber material 91 is first attached to the bottom of the steel ring and placed on the locking block mechanism 4; step 2, the locking block is raised, and the rubber material 91 is tightly attached to the bottom of the steel ring; step 3, the vertical plate 33 is erected, and the wrapping cloth on one side of the steel ring is turned over; step 4, the capsule 51 is inflated and bulged, and the wrapping cloth or rubber material 91 on the other side of the steel ring is turned over. The wrapping cloth mentioned in this article is the rubber material 91; step 5, the push plate 61 moves forward, pushing the capsule 51 to press against the rubber material 91; step 6, the capsule 51 pushes the plate 61 back, the capsule 51 falls back, the vertical plate 33 falls back, and the root rolling mechanism 7 rolls the root. The locking block 43 first fits the rubber material 91 at the bottom of the steel ring, and then the vertical plate 33 rotates to fold the rubber material 91 on one side of the steel ring and fit it. After the bottom is fitted, it is limited by the locking block 43 to restrict the movement of the steel ring. The vertical plate 33 will lift the rubber material 91 on one side; the capsule 51 on the other side is inflated to lift the rubber material 91, and then the push plate 61 pushes the capsule 51 to press the rubber material 91 tightly on the steel ring; these two sides fit separately, and one side is the vertical plate 33, which can prevent the bottom two sides of the steel ring from fitting loosely. The pressure roller 72 rolls the rubber material 91 on the upper part of the steel ring to solve the problem of loose fitting on the upper part of the steel ring.

[0041] A cloth wrapping method includes the following steps: 1. placing the rubber material 91 and the steel ring in a set position;

[0042] Step 2: The locking block 43 is raised to press the rubber material 91 against the lower side of the steel ring; the cylinder 2 41 moves along the main shaft 2, driving the extension rod to rotate, and the extension rod lifts the locking block 43, so that the locking block 43 lifts the rubber material 91.

[0043] Step 3: The vertical plate 33 rotates to stick the rubber material 91 to one side of the steel ring; the cylinder 1 31 moves along the active direction, driving the connecting rod 1 32 to rotate, thereby driving the vertical plate 33 to rotate.

[0044] Step 4: The capsule 51 is inflated to push up the rubber material 91, and the rubber material 91 is attached to the other side of the steel ring; the air flow enters the capsule 51 from the airway 53, and inflates the airbag.

[0045] Step 5: The push plate 61 pushes the capsule 51 to attach the rubber material 91 to the other side of the steel ring;

[0046] Step 6: The push plate 61 returns, the capsule 51 falls back, the vertical plate 33 falls back, and the pressure roller 72 presses the root; the pressure roller cylinder 71 drives the pressure roller 72 to extend toward the steel ring, and the main shaft 2 rotates the pressure roller 72 along the root of the steel ring to press the rubber material 91 on the steel ring.

[0047] The above description is merely the best embodiment of the present invention and is not intended to limit the present invention in any form. Any person skilled in the art who uses the above-disclosed methods and contents to make many possible changes and modifications to the present invention without departing from the scope of the technical solution of the present invention shall fall within the scope of protection of the claims.
