Description

Technical Field

[0001] The present application relates to the field of spherical ball production equipment, and in particular to an automatic grinding machine for a mid-tire parting line. Background Art

[0002] During the production of the spherical tire, a vulcanizer is required to vulcanize and mold to form the tire sphere, and then the subsequent skinning process is carried out to produce the finished ball (basketball, football, volleyball, rugby, etc.).

[0003] After the middle tire sphere is vulcanized and molded, a protruding mold line will be formed in the middle position, so it needs to be polished flat to ensure the smoothness of subsequent skinning. The existing technology usually polishes the mold line of the middle tire sphere by manual sanding belt polishing or manually holding the sphere and polishing it with a motor-driven grinding wheel, which results in low polishing efficiency and needs to be improved.

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The embodiment of the present application discloses an automatic grinding machine for the middle tire parting line. Figure 1 and Figure 2The automatic grinding machine includes a frame 1, a placement seat 2, a clamping seat 3, a clamping drive assembly 4 and a grinding assembly 5. The placement seat 2 is horizontally rotatably connected to the frame 1 and is used to place the middle tire ball 7. The clamping seat 3 is located above the placement seat 2. The clamping drive assembly 4 is installed on the frame 1 and is used to drive the clamping seat 3 to move up and down and rotate, thereby clamping and driving the middle tire ball 7 to rotate. The grinding assembly 5 is installed on the frame 1 on one side of the placement seat 2 and is used to grind the parting line 71 of the middle tire ball 7. The middle tire ball 7 is placed on the placement seat 2. The clamping drive assembly 4 drives the clamping seat 3 to move downward to cooperate with the placement seat 2 to clamp the middle tire ball 7, and at the same time drives the clamping seat 3 to rotate, thereby rotating the middle tire ball 7. Then the grinding device cyclically grinds the parting line 71 in the middle position of the middle tire ball 7, thereby improving the grinding efficiency and quality of the middle tire parting line 71.

[0028] Specifically, the grinding assembly 5 includes a grinding wheel 51, a driving source 52, a driving block 53, and a first motor 54. The grinding wheel 51 includes a mounting roller 511 and hard bristles 512 distributed circumferentially on the mounting roller 511. The output shaft of the first motor 54 is coaxially fixedly connected to the mounting roller 511. The first motor 54 is mounted on the driving block 53, and the driving block 53 is mounted on the output shaft of the driving source 52. The driving source 52 is used to push the grinding wheel 51 to the grinding position or the yielding position. The grinding position is located in the middle position between the clamping seat 3 and the placement seat 2, so that the grinding wheel 51 contacts the mold line 71 in the middle of the middle tire sphere 7. The grinding wheel 51 is arranged to rotate vertically, while the mold line 71 of the middle tire sphere 7 rotates horizontally, so that the grinding wheel 51 automatically reciprocates to grind the mold line 71 of the middle tire sphere 7.

[0029] The driving source 52 in this application is a cylinder, and a multi-axis cylinder is used. The cylinder is horizontally mounted on the movable base 63, which can enable the driving source 52 to stably drive the grinding wheel 51 and facilitate the control of the grinding wheel 51 in the grinding position or the yielding position. In other embodiments, a motor and a connecting rod can also be used.

[0030] Furthermore, an adjustment assembly 6 for adjusting the distance between the grinding wheel 51 and the middle tire ball 7 is also included. The adjustment assembly 6 includes a mounting seat 61, a screw 62, a movable seat 63, a guide rod 64, and an adjustment member 65. The mounting seat 61 is fixedly mounted on the frame 1, the screw 62 is horizontally rotatably connected to the mounting seat 61, the movable seat 63 is threadedly connected to the screw 62, and the guide rod 64 is arranged parallel to the mounting seat 61 on one side of the screw 62. Two guide rods 64 are provided in the present application, and the screw 62 is located between the two guide rods 64. The movable seat 63 is movably sleeved on the guide rod 64, the driving source 52 is mounted on the movable seat 63, and the adjustment member 65 is coaxially fixedly connected to the screw 62 for driving the screw 62 to rotate. The screw rod 62 is driven to rotate by the adjusting member 65, thereby adjusting the position of the movable seat 63, and then adjusting the position of the grinding wheel 51, so as to adapt to the grinding of the tire ball 7 that cannot be adjusted, and at the same time, the grinding pressure of the grinding wheel 51 can also be adjusted, thereby improving the grinding efficiency.

[0031] The adjusting member 65 in the present embodiment is a handle, which is convenient for rotating the screw rod 62 and can achieve fine adjustment at the same time. In addition, in other embodiments, a private motor can also be used to drive the screw rod 62 to rotate accurately.

[0032] Specifically, the clamping drive assembly 4 includes a mounting plate 41, a pusher 42, a pusher plate 43, and a second motor 44. The mounting plate 41 is vertically fixedly mounted on the frame 1. The pusher 42 is mounted on the frame 1 through the mounting plate 41. The pusher plate 43 is fixedly mounted on the output shaft of the pusher 42. The second motor 44 is mounted on the pusher plate 43. The clamping seat 3 is rotatably connected to the rotating shaft of the second motor 44. The pusher 42 drives the pusher plate 43 to move downward, thereby causing the second motor 44 to drive the clamping seat 3 to move downward, cooperating with the placement seat 2 to clamp the middle tire ball 7. Then, the second motor 44 drives the clamping seat 3 to rotate, thereby driving the middle tire ball 7 to rotate.

[0033] The pusher 42 in this embodiment is a cylinder, and a multi-axis cylinder is used. The pusher 42 is a cylinder that can stably and conveniently control the up and down movement of the clamping seat 3.

[0034] Furthermore, the surfaces of the placement seat 2 and the clamping seat 3 have arcuate grooves 21. The arcuate grooves 21 on the surfaces of the placement seat 2 and the clamping seat 3 can improve the stability of the rotation of the middle tire ball 7.

[0035] The first motor 54 and the second motor 44 are both private motors. The operation of the first motor 54 and the second motor 44 can be precisely controlled by the private motor and the private controller.

[0036] The implementation principle of an automatic grinder for the middle tire mold line 71 of an embodiment of the present application is as follows: the middle tire ball 7 is placed on the placement seat 2, the clamping drive assembly 4 drives the clamping seat 3 to move downward to cooperate with the placement seat 2 to clamp the middle tire ball 7, and then the second motor 44 drives the clamping seat 3 to drive the middle tire ball 7 to rotate, and then the grinding wheel 51 located in the middle position on one side of the middle tire ball 7 rotates under the drive of the first motor 54, automatically grinding the mold line 71 in the middle position of the middle tire ball 7, thereby improving the grinding efficiency and quality of the middle tire mold line 71.
