[0025] In order to solve the problem of poor adjustability of drum specifications of apex glue laminating machines in the prior art, the present invention provides an apex glue forming drum device.

[0026] like Figure 1 The apex rubber forming drum device shown includes a spindle frame 10, a flap 20, a first adjusting device 30 and a second adjusting device 40. The flap 20 is sleeved on the outside of the spindle frame 10 and is movably connected to the spindle frame 10. The first adjusting device 30 and the second adjusting device 40 are movably arranged relative to the spindle frame 10, and are respectively connected to the two axial ends of the flap 20, and respectively drive the two ends of the flap 20 to expand outward or contract inward to change the position of the flap 20 relative to the spindle frame 10.

[0027] In this embodiment, the first adjusting device 30 and the second adjusting device 40 are provided. When changing specifications, the two ends of the flap 20 can be adjusted respectively by the first adjusting device 30 and the second adjusting device 40, so that the flap 20 can expand outward or contract inward, so that the apex forming drum device is adapted to the specifications of the steel ring and the apex, thereby improving the versatility and adaptability of the apex forming drum device, facilitating the subsequent continuous fitting of the apex and the steel ring, realizing the automation of the equipment, and making the entire adjustment process easy to operate, saving time and improving efficiency.

[0028] In this embodiment, the first adjusting device 30 includes a first screw 31, a first nut 32 and a first transmission assembly 33. The first screw 31 is inserted into the spindle frame 10 and is rotatable relative to the spindle frame 10. A thread is provided on a section of the first screw 31. The first nut 32 is sleeved on the outside of the threaded section of the first screw 31, so as to cooperate with the thread of the first screw 31. When the first screw 31 is rotated, the first screw 31 will drive the first nut 32 to move axially; the two ends of the first transmission assembly 33 are respectively connected to the first nut 32 and one end of the flap 20. When the first nut 32 moves, it will drive the first transmission assembly 33 to move, and the flap 20 is driven by the first transmission assembly 33 to realize the outward expansion or inward contraction of the flap 20.

[0029] Optionally, the first screw rod 31 has a first operating end, which is exposed on the spindle frame 10, and a polygonal protrusion or countersunk hole may be provided on the first operating end to facilitate the use of a tool to rotate the first screw rod 31. Of course, an external device may also be connected to the first screw rod 31 to achieve automatic adjustment.

[0030] In this embodiment, the first transmission assembly 33 includes a first sliding plate 331 and a first connecting rod group 332. The first sliding plate 331 is sleeved on the spindle frame 10 and abuts against the first nut 32. The first sliding plate 331 moves axially along the spindle frame 10 under the extrusion and drive of the first nut 32. The two ends of the first connecting rod group 332 are respectively connected to the first sliding plate 331 and the flap 20. When the first sliding plate 331 slides, the first sliding plate 331 squeezes the first connecting rod group 332. The connecting rods of the first connecting rod group 332 cooperate with each other to transmit power to the flap 20, thereby driving the flap 20 to move.

[0031] Similar to the structure of the first adjusting device 30, the second adjusting device 40 includes a second screw 41, a second nut 42 and a second transmission assembly 43. The second screw 41 is rotatably inserted into the spindle frame 10. The second screw 41 also has a threaded section. The second nut 42 is sleeved on the outside of the threaded section of the second screw 41, so as to be threadedly matched with the second screw 41. When the second screw 41 is rotated, the second screw 41 will drive the second nut 42 to move axially; one end of the second transmission assembly 43 is connected to the second nut 42, and the other end of the second transmission assembly 43 is connected to the end of the flap 20 away from the first transmission assembly 33. The second nut 42 drives the second transmission assembly 43 to move, and the flap 20 is driven to move by the second transmission assembly 43 to realize the outward expansion or inward contraction of the flap 20.

[0032] In this embodiment, the second screw 41 is sleeve-shaped and sleeved on the outside of the first screw 31, and the second screw 41 rotates independently with the first screw 31. The first screw 31 has a relatively long overall length, and includes a first large diameter section, a small diameter section, and a second large diameter section connected in sequence. One end of the second screw 41 is located on the first large diameter section, and the other end is located on the second large diameter section. In this way, the middle of the second screw 41 cooperates with the small diameter section to avoid wear caused by mutual contact between the two, and bearings are provided between the first large diameter section and the second screw 41 and between the second large diameter section and the second screw 41. The bearings reduce the wear between the first screw 31 and the second screw 41, which is conducive to smooth relative rotation between the two.

[0033] Similar to the first operating end, the second screw rod 41 has a second operating end, and the second operating end is exposed from the spindle frame 10. The second operating end can also be provided in the form of a polygonal protrusion or a countersunk hole, or can be operated automatically.

[0034] Preferably, the first operating end and the second operating end are located on the same side of the spindle frame 10, and the first adjusting device 30 is connected to the end of the flap 20 away from the first operating end, and the second adjusting device 40 is connected to the end of the flap 20 close to the first operating end. In this way, when adjustment is required, the flap 20 is adjusted from the same position by the first adjusting device 30 and the second adjusting device 40, and in order to keep the flap 20 always horizontal, both ends of the flap 20 need to be achieved by synchronously adjusting the first adjusting device 30 and the second adjusting device 40.

[0035] In this embodiment, the second transmission assembly 43 includes a second sliding plate 431 and a second connecting rod group 432. The second sliding plate 431 is sleeved on the spindle frame 10. The second nut 42 abuts against the second sliding plate 431. The second sliding plate 431 moves axially along the spindle frame 10 under the extrusion and drive of the second nut 42. The two ends of the second connecting rod group 432 are respectively connected to the second sliding plate 431 and the flap 20. When the second nut 42 squeezes the second sliding plate 431, the second sliding plate 431 squeezes the second connecting rod group 432. The connecting rods in the second connecting rod group 432 cooperate with each other to transmit power to the flap 20, thereby driving the flap 20 to move.

[0036] In this embodiment, the apex forming drum device further includes a driving assembly 50, which is drivingly connected to the first adjusting device 30 and drives the flap 20 to flip through the first adjusting device 30. The driving assembly 50 is preferably a cylinder, the piston of which is fixedly connected to the first sliding plate 331, and the cylinder body drives the piston to move, thereby driving the flap 20 to flip 90 degrees through the first sliding plate 331 and the first connecting rod group 332, and flipping the apex onto the steel ring of the subsequent process. A gap is formed between the outer edge of the piston and the first sliding plate 331, and the outer edge of the first nut 32 extends into the gap, thereby squeezing the first sliding plate 331 and the piston, and realizing the movement of the flap 20 inward and outward directions.

[0037] like Figure 2 As shown, the apex rubber forming drum device also includes a first locking device 60 and a second locking device 70. The first locking device 60 is connected to the spindle frame 10, and a portion of the first locking device 60 can pass through the first through hole on the spindle frame 10 and extend into the first adjusting device 30 to hinder the movement of the first adjusting device 30 and lock the first adjusting device 30; the second locking device 70 is connected to the spindle frame 10, and a portion of the second locking device 70 can pass through the second through hole on the spindle frame 10 and extend into the second adjusting device 40 to hinder the movement of the second adjusting device 40 and lock the second adjusting device 40.

[0038] Specifically, the first locking device 60 includes a locking plate, which is arranged in a fan shape and has a protrusion on the inner side. Accordingly, a first through hole is opened on the spindle frame 10, and a groove is opened on the side of the first screw 31. The protrusion passes through the first through hole and extends into the groove to lock the first screw 31, thereby locking the first adjusting device 30. The first locking device 60 is rotatable along the circumference of the spindle frame 10, and an arc-shaped hole is opened near the outer edge of the locking plate. The bolt is connected to the spindle frame 10 after passing through the arc-shaped hole. In this way, the locking plate can be rotated at a certain angle relative to the spindle frame 10. When the rotation adjustment of the first screw rod 31 is completed, the position of the locking plate can be adjusted so that the protrusion, the first through hole and the groove are aligned. The protrusion can be inserted into the groove for locking. Since the first through hole is on the spindle frame 10, its position cannot be adjusted. Therefore, a plurality of first through holes are provided and arranged along the circumference of the spindle frame 10, that is, arranged along the circumference of the first screw rod 31. In this way, the locking plate can cooperate with different first through holes respectively to ensure that the protrusion is inserted into the groove only after passing through the first through hole, thereby ensuring the reliability of the first locking device 60. The second locking device 70 is arranged in a substantially similar manner to the first locking device 60 , except that the two are arranged at different axial sections of the spindle frame 10 to respectively cooperate with the first screw rod 31 and the second screw rod 41 .

[0039] Preferably, the first locking device 60 and the second locking device 70 are arranged on the same side of the spindle frame 10 and are both on the front side of the apex rubber forming drum. This is convenient for adjustment and has a compact structure. It only requires special tools for adjustment, which facilitates the subsequent continuity and automation of the equipment.

[0040] It should be noted that, the multiple in the above embodiments refers to at least two.
