DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings and specific embodiments to clearly and completely describe the technical solution of the utility model. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the utility model and cannot be understood as limiting the scope of protection of the utility model. Technical personnel skilled in the art can make some non-essential improvements and adjustments based on the content of the utility model described below. In the utility model, unless otherwise clearly specified and limited, the technical terms used in this application should be the common meanings understood by the technical personnel described in the utility model.

[0025] like Figure 1 As shown, the mechanical building drum 1 includes a set of symmetrical turn-up devices 2. During the tire blank forming process, the turn-up action is achieved by the cylinder inside the turn-up device 2 driving the turn-up rod. The turn-up device 2 is the side drum of the building drum 1. For example, CN216914924U discloses a connection between the turn-up rod and the cylinder in a turn-up rod pressure control device for a mechanical building drum.

[0026] Therefore, the exhaust device of the mechanical forming drum turn-up device of the present application comprises two quick-connect connectors 5 installed on the end covers at both ends of the turn-up device 2; the quick-connect connectors 5 are connected to the cylinder body inside the turn-up device 2;

[0027] Two radial air hole interfaces are respectively provided at both ends of the main shaft 3 of the forming drum 1, each of which is provided with a throttle valve 4, each of which is connected to a quick-connection connector 5 at the corresponding end, and the quick-connection connector 5 is connected to the throttle valve 4 through a hose 6; thereby, the air hole inside the main shaft 3 of the forming drum 1 and the cylinder body inside the turn-up device 2 are connected;

[0028] A transmission main shaft 8 is installed in a driving chassis 7 (a motor and a reducer are installed in the driving chassis, and the motor and the reducer drive the transmission main shaft to rotate). A rotary valve 10 is installed outside the transmission main shaft 8 in the driving chassis 7. A silencer 12 and a quick exhaust valve 11 are also provided in the driving chassis 7. The quick exhaust valve 11 includes an air source interface a, a functional interface b and an exhaust interface c.

[0029] The radial air hole interface of the main shaft 3 of the forming drum 1 is connected to the air path of the driving chassis transmission main shaft 8 through the air path, and each air path of the driving chassis transmission main shaft 8 is connected to the air source through the rotary valve 10. At least one quick exhaust valve 11 is installed on each rotary valve 10. The rotary valve 10 is respectively connected to the air source and the silencer 12 through the quick exhaust valve 11. The silencer 12 is connected to the radial air holes of the main shaft 3 of at least two forming drums 1. The air source interface a of the quick exhaust valve 11 is connected to the air source, the functional interface b of the quick exhaust valve 11, i.e., the working interface, is connected to the rotary valve 10 through the hose 6, and the exhaust interface c is connected to the silencer 12 through the hose 6.

[0030] The rotary valve 10 is arranged on the driving chassis transmission main shaft 8. The rotary valve is connected to the driving chassis transmission main shaft 8 through radial air holes 80 opened on the transmission main shaft and the air path of the transmission main shaft 8. The number of air paths of the transmission main shaft 8 corresponds to the number of rotary valves.

[0031] The rotary valve 10 includes an annular sleeve 100 which is sleeved on the outside of the transmission main shaft 8 of the driving chassis. An annular groove 101 corresponding to the radial air hole 80 provided on the transmission main shaft 8 is provided on the side surface of the annular sleeve 100 corresponding to the transmission main shaft 8. A connecting hole 102 which connects the annular groove 101 and the functional interface b of the quick exhaust valve 11 is provided on the annular sleeve 100. The annular sleeve 100 is rotatably connected to the transmission main shaft 8, so that as the transmission main shaft 8 of the driving chassis rotates, it can be ensured that the air supply to the air path in the transmission main shaft 8 is not affected, and the air path exhaust in the transmission main shaft 8 is not affected.

[0032] The specific connection mode of the rotatable connection between the annular sleeve 100 and the transmission main shaft 8 is as follows: on both sides of the annular groove 101 , the annular sleeve is connected to the outside of the transmission main shaft 8 in the driving chassis through annular sealing rings 103 .

[0033] Air intake into the internal cylinder of the turn-up device 2: the air from the air source is transported into the rotary valve 10 through the air source interface a and the functional interface b of the quick exhaust valve 11, and then enters the corresponding air paths of the transmission main shaft 8 and the main shaft 3 of the forming drum 1, and then enters the cylinder inside the turn-up device 2; when the internal cylinder of the turn-up device 2 is exhausted, the gas of the internal cylinder of the turn-up device 2 enters the corresponding air paths of the main shaft 3 and the transmission main shaft 8 through the radial air hole interfaces at both ends of the main shaft 3 of the forming drum 1, and then enters the rotary valve, and enters the silencer 12 through the functional interface b and the exhaust interface c of the quick exhaust valve 11.

[0034] The air intake and exhaust of the anti-packing device are realized by exhausting or exhausting the air through the air path.

[0035] The throttle valve 4 is an exhaust throttle valve, which is used to adjust the turn-up speed of the turn-up device 2. Therefore, when the turn-up action is in progress, by adjusting the exhaust throttle valve on the main shaft of the forming drum, the speed and synchronization of the turn-up action on both sides of the mechanical forming drum 1 can be adjusted respectively, and the synchronization of the turn-up on both sides of the tire blank can be adjusted.

[0036] The interface specification of the quick exhaust valve 11 is selected to be an interface G1 / 2 or above to ensure the exhaust flow rate and speed. The quick exhaust valve 11 can be FESTO brand, model SE-1 / 2-B.

[0037] The silencer is a silencer with a large flow rate (the large flow rate is preferably a flow rate of not less than 30m³ / min). The use of a silencer with a large flow rate can quickly exhaust air due to the large flow rate. Also, due to the large flow rate, the silencer has a large space, and the sound-absorbing material or the sound-silencing material has a large volume. It takes longer for impurities to adhere and affect the exhaust effect, which can extend the maintenance cycle. Also, due to the large flow rate and the large space of the silencer, it is convenient to take out the sound-absorbing material or the sound-silencing material in the silencer for cleaning, so it can play a role in rapid exhaust, convenient cleaning and extending the maintenance cycle. The exhaust interfaces c of each quick exhaust valve are connected to the silencer through a hose to achieve the effect of centralized exhaust and silencing. The silencer is a silencer of the Japanese SMC pneumatic brand, model ANA1-14, ANA1-20.

[0038] At least two rotary valves 10 are connected to the silencer cylinder via a quick exhaust valve 11 .

[0039] There are at least three rotary valves 10 and corresponding quick exhaust valves. Because this article is about the turn-up function air circuit, it occupies 3 air circuits, 2 of which are the rising air circuits of the two side drum turn-up rods, and 1 is the falling air circuit of the turn-up rods shared by the two side drums, so the 3 air circuits are connected to a rotary valve 10 respectively.

[0040] The inlet of the silencer 12 is provided with an interface flange 13, and the interface flange 13 is provided with at least 3 G1 / 2 interfaces. The flange interface can be a G1 / 2 threaded interface. The unused flange interface can be plugged with a plug 14 first.

[0041] The sufficient interfaces of the muffler interface flange 13 can not only eliminate the anti-packing noise of the mechanical drum, but also connect the exhaust of the expansion and contraction function of the belt drum 15 to eliminate the exhaust noise of the belt drum 15. For example, the exhaust valve of the belt drum 15 is connected to the interface of the multi-interface flange 13 through a pipeline.

[0042] A connecting flange 9 is installed at one end of the transmission main shaft 8 outside the driving chassis, and the transmission main shaft 8 is connected to the main shaft 3 of the forming drum 1 through the connecting flange 9; an air path is processed inside the connecting flange, and the air path of the transmission main shaft 8 and the air path of the main shaft 3 of the forming drum 1 are connected through the connecting flange air path.

[0043] The exhaust process of the device of the utility model is as follows: when the cylinder in the mechanical forming drum reverse package device is exhausted, the airflow enters the air path in the main shaft of the forming drum through the throttle valve, then enters the air path of the transmission main shaft through the connecting flange air path and flows to the rotary valve 10, and the rotary valve 10 flows into the interior of the silencer through the exhaust interface c of the connected quick exhaust valve. As a result, the reverse package noise during the operation of the forming drum is basically eliminated, achieving "silent reverse package", effectively achieving the purpose of complying with noise standards and improving the working environment of operators.

[0044] The whole working process of the utility model is as follows: the air source passes through the air source interface a of the quick exhaust valve 11, and then enters the rotary valve 10 inside the driving chassis 7 through the functional air port b, and then enters the air path of the transmission main shaft 8, and then enters the cylinder body of the turn-up device / side drum 2 of the building drum through the connection flange 9, the main shaft 3 of the building drum, the exhaust throttle valve and other paths, and the turn-up cylinder bodies on both sides respectively push the corresponding turn-up rods of one circle to complete the turn-up action of the tire embryo. Adjusting the exhaust throttle valve 4 can adjust the turn-up speed of the turn-up device 2 and the synchronization of the turn-up on both sides. During the turn-up action, the exhaust gas of the cylinder body 2 in the turn-up device returns to the quick exhaust valve 11 along the air path, and is discharged from the exhaust port c of the quick exhaust valve 11 into the silencer 12, and the silencer is used to complete the silencer and discharge to the internal space of the driving chassis 7.

[0045] Because the exhaust of the silencer is transferred to the drive chassis, this exhaust position transfer plays a role in isolating the exhaust noise; on the other hand, the silencer with large flow and multiple interfaces installed inside the chassis also plays a silencing effect. With the help of these two measures, the so-called "silent anti-packing" effect or greatly reduced exhaust noise was achieved at the employee's work site, the noise standard was met and compliant, and the employees had a good experience on site.

The technical features of the above embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above embodiments are not described.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention. It should be pointed out that for those skilled in the art and any technician familiar with the technical field, without departing from the spirit of the overall concept of the present invention and the principle of the present invention, equivalent replacement or change according to the technical solution and its utility model concept of the present invention, and several changes and improvements made should also be regarded as the protection scope of the present invention.
