Description

Technical Field

[0001] The utility model relates to the technical field of tires, and particularly relates to a device for automatically pasting sound-absorbing cotton on tires. Background Technique

[0002] In the current automotive tire manufacturing and post-treatment industries, the pasting of sound-absorbing cotton is an important and complex process. Sound-absorbing cotton is mainly used to improve the noise reduction performance of tires, thereby enhancing the comfort of passenger vehicles. However, the traditional method of pasting sound-absorbing cotton mainly relies on manual installation, which has many deficiencies.

[0003] Firstly, manual installation of sound-absorbing cotton is time-consuming and laborious, with low efficiency. With the continuous increase in automobile production, the manual installation method is difficult to meet the requirements of large-scale production. Secondly, due to the uneven technical levels of workers, problems such as inconsistent installation standards often occur during manual installation, resulting in the difficulty of ensuring the sound insulation effect of tires and even the possible decline in the sound insulation effect.

[0004] In addition, due to the large variety of tire models, the corresponding sound-absorbing cotton also has various specifications, including different widths and thicknesses. During manual installation, it is necessary to cut the sound-absorbing cotton to the appropriate size according to the specific tire model, which not only increases the operation difficulty but also easily leads to material waste. More seriously, if the distance between the two fixed shafts of the clamping part is set improperly, the sound-absorbing cotton cannot be correctly clamped, thereby affecting the pasting effect. For example, if the distance between the two fixed shafts is too small and the clamping force is too large, the sound-absorbing cotton may not be able to pass through the clamping part or damage the equipment; if the distance is too large, the clamping force decreases or even disappears, which may cause the sound-absorbing cotton to fall off during transportation and result in pasting failure.

[0005] Therefore, how to improve the accuracy and efficiency of pasting tire sound-absorbing cotton, reduce costs, and at the same time ensure the consistency and stability of installation quality has become an urgent problem to be solved in the current automotive tire manufacturing field.

[0038] As Figures 1 to 6As shown in the figure, this embodiment discloses a device for automatically pasting soundproof cotton on tires. The device includes a storage mechanism 1, a rotating mechanism 2, a pasting mechanism 3, and a cutting mechanism 4.

[0039] The storage mechanism 1 is arranged on one side of the device and is used to store the soundproof cotton. The storage mechanism 1 includes a semi-circular storage disk 11, and a clamping wheel group 12 is arranged on the arc surface side. The clamping wheel group 12 includes a lower clamping wheel 122 at a fixed position and an upper clamping wheel 121 that can be controlled to move up and down by a pressing cylinder 123. The pressing cylinder 123 controls the movement of the upper clamping wheel 121 to adjust the clamping degree of the soundproof cotton.

[0040] The rotating mechanism 2 is responsible for fixing the tire and rotating it to facilitate the pasting of the soundproof cotton. This mechanism is divided into an upper rotating mechanism 21 and a lower rotating mechanism 22. The lower rotating mechanism 22 includes a tread clamping wheel group 12, in which the first roller 221 is fixed in position, and the second roller 222 can be driven by a cylinder to move along the guide rail to adjust the distance between the two to adapt to tires of different diameters. Similarly, the sidewall clamping wheel group 12 in the lower rotating mechanism 22 also includes a third roller 223 and a fourth roller 224, and the distance between the two can be adjusted by a cylinder to adapt to tires of different widths. A plurality of the third roller 223 and the fourth roller 224 are provided to facilitate the stable clamping of the tire.

[0041] As Figure 3 shown, the upper rotating mechanism 21 also includes a tread clamping wheel group 12 and a sidewall clamping wheel group 12. Different from the lower rotating mechanism 22, the first roller 221 in the tread clamping wheel group 12 can move up and down driven by a cylinder, and the second roller 222 can also move up and down driven by a cylinder. Adjusting the height of the sidewall clamping wheel group 12 can move up and down driven by the lifting rod mechanism 211, and at the same time, the lifting rod mechanism 211 can drive the tread clamping wheel group 12 to move up and down as a whole. One end of the screw of the lifting rod mechanism 211 is fixedly installed on the upper top plate, and the screw head is installed on the upper cross beam. By rotating the screw head, the upper tread clamping wheel group 12 and the sidewall clamping wheel group 12 are driven to rise and fall.

[0042] The core of the pasting mechanism 3 is the pressing head 31, which is realized by the cooperation of multiple cylinders to achieve multi-dimensional adjustment. The pressing head 31 is mounted on the third moving mechanism 34, which is mounted on one end of the second moving mechanism 33, and the second moving mechanism 33 is mounted on one end of the first moving mechanism 32. Such a design allows the pressing head 31 to be adjusted in the vertical direction (through the first moving mechanism 32), the horizontal direction (through the second moving mechanism 33) and the feeding direction (through the third moving mechanism 34). The pressing head 31 itself includes a pressing roller 312 fixed on the frame 311, a guide roller 313 with adjustable height mounted on the frame 311 through a guide cylinder, and a cutting mechanism 4 located between the pressing roller 312 and the guide roller 313. The cutting mechanism 4 has a built-in electric heating wire 41 for cutting the silent cotton.

[0043] The first moving mechanism 32 includes a first cylinder and a first guide rail, and the second moving mechanism 33 is installed at one end of the first cylinder. The first guide rail limits the second moving mechanism 33 to move in the up and down directions; the second moving mechanism 33 includes a linear guide slider mechanism and a second cylinder. The guide rail of the linear guide slider mechanism is set at one end of the first cylinder, and the moving direction is limited by the first guide rail. The slider of the linear guide slider mechanism is provided with a second cylinder, and the second cylinder moves left and right on the linear guide slider mechanism. The linear guide slider mechanism is an electromagnetic linear guide slider. The second cylinder further provides a moving distance in the left and right directions. The third moving mechanism 34 is set at one end of the second cylinder. The third moving mechanism 34 is a magnetic coupling type non-inductive cylinder. The frame 311 is installed on the magnetic coupling type non-inductive cylinder, thereby providing movement in the front and back directions.

[0044] The cutting mechanism 4 is integrated with the pressing head 31 , and the electric heating wire 41 in the cutting mechanism 4 is used to accurately cut the silent cotton after it reaches a predetermined position.

[0045] like Figure 6 As shown, during the pasting process, the guide wheel 5, the guide roller 313 and the pressure roller 312, the tire rotates clockwise, and the silent cotton is pasted counterclockwise upward. When the pasting is completed, the guide roller 313 is lifted, and the silent cotton is also lifted. The silent cotton hits the heating wire of the cutting mechanism and cuts the silent cotton.

[0046] In order to ensure the smooth operation of the silent cotton during the pasting process, the device is provided with a guide wheel 5 on one side to help the silent cotton be transferred to the tire surface along the correct path. A conveying wheel 6 is also provided on one side of the device to facilitate the installation of the tire on the device and save manpower.

[0047] When starting work, the tire is fed into the rotating mechanism 2 and fixed. Then, the soundproof cotton in the storage mechanism 1 is taken out and sent to the position below the pressing head 31 through the transmission mechanism. At this time, by adjusting each cylinder, the pressing head 31 is accurately aligned with the inner wall of the tire. The pressing head 31 descends, presses the soundproof cotton and presses it on the tire, and then cuts off the excess soundproof cotton through the heating wire 41. After the tire rotates a certain angle, the above steps are repeated until the entire inner wall of the tire is covered with soundproof cotton.

[0048] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
