Description

Technical Field

[0001] The utility model belongs to the technical field of tire molding, and particularly relates to a tire body puncturing and exhausting device for molding a full-steel radial tire. Background Art

[0002] The blank of all-steel radial tire is generally formed by a one-step two-drum forming machine. After the sidewall, inner liner, bead reinforcement layer, carcass, and cushion rubber are bonded and rolled on the main drum, the bead is buckled to form a main drum composite. At the same time, the auxiliary drum is used to bond the 1#, 2#, 3#, 4# / 0° belt layer and tread to form an auxiliary drum composite. After the transfer ring transfers the auxiliary drum composite to the appropriate position of the main drum, the main drum forming drum maintains appropriate fan-shaped block pressure, and the middle drum is inflated with air pressure to perform pre-forming, finalizing, and super-forming operations to form a tire blank. Figure 2 As shown, the main drum upper sidewall ( Figure 2 The thickest part near the center of the main drum is generally 3-10mm thick. Figure 2 203) has a thickness of 1.5-3mm. If it is a heavy-duty product, one or two layers of nylon reinforcement layers (about 1.15-2.5mm) are used. In this way, after the carcass is attached, it is easy to Figure 2 Gaps are formed between the tire and the inner liner, causing hidden dangers in product quality, affecting the uniformity and durability of the tire, shortening the service life of the tire, and even causing the sidewall and shoulder of the tire to delaminate or even explode during use, affecting the reputation of the tire brand.

[0003] By using the exhaust roller pressing operation, the parts can be fitted more tightly without leaving any gaps, otherwise bubbles are easily formed in the tire, resulting in defective tires. In traditional operations, in order to roll more tightly, workers use awls and rotate the main drum for one circle to manually pierce the holes before rolling. This operation is not only inefficient, but also increases the operating risk of the operator due to the rotation, which poses a personal safety hazard. At the same time, improper operation will also affect product quality. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described and illustrated in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments provided by the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] The utility model embodiment provides a tire body 204 puncturing and exhausting device for forming an all-steel radial tire. Figure 1 Schematic diagram of the structure of the puncturing and exhausting device for the carcass 204 for forming a full steel radial tire according to an embodiment of the utility model. Figure 1 As shown, the device at least includes a main frame 101, a cantilever 102, an angle adjustment member, a rotating wheel 103, and an exhaust assembly; one end of the cantilever 102 is rotatably connected to the main frame 101; the angle adjustment member is connected to the main frame 101 and the cantilever 102, and adjusts the rotation angle of the cantilever 102 relative to the main frame 101; the rotating wheel 103 is connected to the other end of the cantilever 102, and the rotating wheel 103 is rotatably connected to the other end of the cantilever 102; the exhaust assembly includes a plurality of mounting members arranged on the outer circumference of the rotating wheel 103, and a pin 104 that can be detachably fixedly connected to the mounting member, and the outer end of the pin 104 is a pointed structure. Further, the angle adjustment member is an adjustable rotating knob, which is arranged at the connection between the cantilever 102 and the main frame 101; the rotating wheel 103 is rotatably connected to the other end of the cantilever 102 through a rolling axis. Among them, the cantilever 102 is installed on the main frame 101, and an adjustable rotating knob is provided at the connection between the cantilever 102 and the main frame 101, which can adjust the puncturing position according to production needs (adjusted according to the production construction and material distribution of different products, generally positioned 10-20 cm away from the sub-mouth reinforcement layer 203); the cantilever 102 is the intermediate connecting piece between the rotating wheel 103 and the main frame 101, which can make the rotating wheel 103 rotate stably and make the exhaust holes arranged in a row with a fixed spacing; the rotating wheel 103 is installed on a rolling shaft on the cantilever 102. When the carcass 204 delivers material forward, it drives the pin 104 on the rotating wheel 103 to move, and then drives the rotating wheel 103 to rotate.

[0024] The above-mentioned carcass 204 puncturing and exhausting device for forming all-steel radial tires is easy and quick to operate. When the forming machine needs to switch production and construction, the positioning of the device can be quickly adjusted according to the construction requirements. The operation process is stable and will not damage the quality of the carcass 204 cord. Moreover, the position and spacing of the output exhaust holes are stable, which replaces the traditional manual puncturing. The arrangement of the small holes conforms to the construction settings, and the puncturing force is fixed, which avoids the instability of human factors and ensures product quality. At the same time, it also avoids the hidden safety hazards caused by the rotating main drum, and can save the operator's physical strength. This step is completed while the carcass 204 is feeding forward, eliminating the time for the operator to rotate the main drum for another week to puncture holes in the traditional practice, saving 15-30 seconds and increasing production efficiency by 5%-10%. In addition, after using this device, the incidence of bubbles and delamination defects in the tire products is greatly reduced.

[0025] In order to ensure the stability of the cantilever 102, a positioning piece 105 is also included. The positioning piece 105 passes through the middle of the cantilever 102. The cantilever 102 and the positioning piece 105 are rotatably connected to prevent the rotating wheel 103 from driving the cantilever 102 to swing up and down during the rotation process, causing uneven puncture spacing and depth, or even damaging the quality of the tire body 204 cord.

[0026] Furthermore, in order to improve the exhaust efficiency and ensure the exhaust effect, the cantilever 102, the angle adjustment member, the rotating wheel 103, and the exhaust assembly are all provided in two sets. The two sets of cantilever 102, the angle adjustment member, the rotating wheel 103, and the exhaust assembly are symmetrically arranged about the central axis of the main machine.

[0027] In some embodiments, the length of the pin 104 is 4-6 cm; 8-12 pins 104 are connected to the outer circumference of the rotating wheel 103; the pin 104 is a sharp nail. The pins 104 on the rotating wheel 103 are sharp nails about 5 cm long and are installed on the rotating wheel 103 through nuts, with 8-12 pins on the circumference, and the spacing between the small holes on the carcass 204 is 6-20 cm.

[0028] Furthermore, the mounting piece is a nut, and an outer thread is provided on the inner outer side of the pin 104. By providing the mounting piece, a corresponding number of pins 104 can be connected to the corresponding positions on the rotating wheel 103 according to actual needs, which is conducive to meeting the exhaust requirements of different tires.

[0029] The working process of the above-mentioned tire body 204 puncturing and exhausting device for forming an all-steel radial tire is as follows: according to the needs, the main frame 101 drives the cantilever 102 to rotate to the corresponding position, and the rotating wheel 103 at one end of the cantilever 102 rotates to drive the pin 104 to rotate, thereby realizing efficient exhaust of the tire body 204.

[0030] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
