The bottle bottoms or bottle caps on the feeding equipment may have different orientations. Before entering the assembly equipment, the bottle bottoms or bottle caps of the feeding equipment need to be adjusted to an orientation suitable for direct use by the assembly equipment. Manual adjustment is not only inefficient, but also prone to leakage. In view of this, the utility model provides a feeding mechanism for adjusting the bottle bottoms or bottle caps of the automatic production line of fire extinguishers, which adjusts the bottle bottoms or bottle caps on the feeding equipment and then outputs them to the assembly equipment.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0018] A downward adjustment mechanism for the bottom and cap of a fire extinguisher bottle, such as Figure 1-Figure 3As shown, it includes a clamping mechanism 1, a direction adjustment driving member 2 and a feeding bin 3. A feeding port 31 is provided at the bottom of the feeding bin 3, and a feeding channel 4 is provided below the feeding bin 3. The feeding port 31 is communicated with the top of the feeding channel 4, and the bottom end of the feeding channel 4 is connected with the assembly equipment of the automatic production line of fire extinguishers and delivers the bottle bottoms or bottle caps therein to the assembly equipment. The clamping mechanism 1 is arranged at the opening of the lower material bin 3, and the clamping mechanism 1 includes a first clamping piece and a second clamping piece. The first clamping piece and the second clamping piece are arranged opposite to each other, and the facing side end surfaces of the two constitute a accommodating cavity. At one end of the accommodating cavity, a first feeding port is formed by the end edge of the first clamping piece and the end edge of the second clamping piece. The first feeding port is communicated with the accommodating cavity, and the bottle bottom or bottle cap of the fire extinguisher can enter or leave the accommodating cavity through the first feeding port. At the other end of the accommodating cavity, a second feeding port is formed by the end edge of the first clamping piece and the end edge of the second clamping piece. The second feeding port is also communicated with the accommodating cavity, and the bottle bottom or bottle cap of the fire extinguisher can enter or leave the accommodating cavity through the second feeding port. The first feeding port and the second feeding port are respectively at two opposite ends of the accommodating cavity.

[0019] The direction adjustment drive member 2 is arranged on the side of the clamping mechanism 1, and the rotating part of the direction adjustment drive member 2 is connected to the clamping mechanism 1. The direction adjustment drive member 2 is a forward and reverse motor, and the direction adjustment drive member 2 can drive the clamping mechanism 1 to rotate forward or reverse. The clamping mechanism 1 is arranged at the port of the unloading bin 3. Driven by the adjustment driving member 2, when the first feeding port and the second feeding port are both outside the unloading bin 3, the clamping mechanism 1 is in the material receiving and feeding position. At this time, the first clamping member or the second feeding member blocks the port of the unloading bin 3, and the bottle bottom or bottle cap of the accommodating cavity can enter the accommodating cavity through the first feeding port or the second feeding port, and the bottle bottom or bottle cap in the accommodating cavity can leave the accommodating cavity through the first feeding port or the second feeding port; when the clamping mechanism 1 rotates to a position where the first material receiving port and the unloading port 31 are correspondingly communicated, the clamping mechanism 1 is in the first material discharging position, at which time the bottle bottom or bottle cap in the accommodating cavity can enter the unloading channel 4 through the first feeding port and the unloading port 31; when the clamping mechanism 1 rotates to a position where the second material receiving port and the unloading port 31 are correspondingly communicated, the clamping mechanism 1 is in the second material discharging position, at which time the bottle bottom or bottle cap in the accommodating cavity can enter the unloading channel 4 through the second feeding port and the unloading port 31. The direction adjustment driving member 2 drives the clamping mechanism 1 to rotate between the material receiving position, the first material discharging position and the second material discharging position.

[0020] When the clamping mechanism 1 receives the material and passes the material position, the bottle bottom or bottle cap is loaded into the accommodating chamber. If the front side of the bottle bottom or bottle cap faces upward, the adjustment driving member 2 drives the clamping mechanism 1 to rotate to the first discharge position, and the bottle bottom or bottle cap enters the discharge channel 4 through the first feeding port and the discharge port 31 under the action of gravity; if the back side of the bottle bottom or bottle cap faces upward, the adjustment driving member 2 drives the clamping mechanism 1 to rotate in the opposite direction to the second discharge position, and the bottle bottom or bottle cap enters the discharge channel 4 through the second feeding port and the discharge port 31.

[0021] The cross section of the material discharge channel 4 is rectangular or elliptical, and the bottle bottom or bottle cap cannot be turned over when moving in the material discharge channel 4, thereby avoiding the change of direction of the bottle bottom or bottle cap during movement.

[0022] In order to prevent the bottle bottom or bottle cap in the accommodating cavity from falling out during the rotation of the clamping mechanism 1, the inner wall of the lower material bin 3 is an arc-shaped surface, and the axis of the inner wall of the lower material bin 3 coincides with the rotation axis of the clamping mechanism 1. When the clamping mechanism 1 rotates so that the first feeding port or the second feeding port is in the lower material bin 3, there is a rotation gap between the first feeding port or the second feeding port and the inner wall of the lower material bin 3, and the inner wall can prevent the bottle bottom or bottle cap in the accommodating cavity from falling out.

[0023] See also Figure 2 and Figure 3 In some embodiments, a loading conveyor 5 is arranged at one side of the opening of the lower material bin 3, and the loading conveyor 5 is provided with a loading conveying channel. The loading conveyor 5 drives the bottle bottom or bottle cap to move along the loading conveying channel, and the clamping mechanism 1 is at the tail end of the loading conveyor 5. When the clamping mechanism 1 receives the material and passes the material level, the accommodating cavity communicates with the loading conveying channel through the first material passing port or the second material passing port, and at this time, the bottle bottom or bottle cap of the loading conveyor 5 can enter the accommodating cavity.

[0024] A forward and reverse detection member 51 is provided at the feeding conveying channel of the feeding conveyor 5. The feeding conveyor 5 conveys the bottle bottoms or bottle caps one by one through the detection position of the forward and reverse detection member 51, and the forward and reverse detection member 51 detects the orientation of the bottle bottoms or bottle caps. When the bottle bottoms or bottle caps conveyed by the feeding conveyor 5 enter the accommodating cavity, the feeding mechanism rotates in the corresponding direction according to the orientation of the bottle bottoms or bottle caps, so that the bottle bottoms or bottle caps enter the unloading channel 4 in a specified orientation and reach the assembly equipment.

[0025] As a specific example, the forward and reverse detection member 51 is a photoelectric switch, which is arranged above the feeding conveying channel and measures the bottle bottom or bottle cap passing below it. When the bottle bottom passes the photoelectric switch with the front side facing upward and when the bottle bottom passes the photoelectric switch with the back side facing upward, the detection result of the photoelectric switch is different. When the bottle cap passes the photoelectric switch with the front side facing upward and when the bottle bottom passes the photoelectric switch with the back side facing upward, the detection result of the photoelectric switch is also different. Therefore, the photoelectric switch can be used to detect the orientation of the bottle bottom and bottle cap.

[0026] In order to enable the bottle bottoms or bottle caps conveyed by the feeding conveyor 5 to enter the accommodating cavity one by one for adaptive adjustment, a blocking mechanism 52 is provided at the end of the feeding conveying channel, and the blocking mechanism 52 includes a blocking end and a blocking driving member, and the blocking driving member is arranged outside the feeding conveying channel, and the action part of the blocking driving member is connected to the blocking end and drives the blocking end to move between the blocking position and the pass position. The blocking driving member is a cylinder or an electric push rod, and when the blocking driving member drives the blocking end to the blocking position, the blocking end extends into the feeding conveying channel and blocks the bottle bottoms or bottle caps from passing through, and when the blocking driving member drives the blocking end to the pass position, the blocking end moves to the outside of the feeding conveying channel, and the bottle bottoms or bottle caps in the feeding conveying channel can pass through the end of the blocking end.

[0027] The loading conveyor 5 cooperates with the lower feeding mechanism to provide bottle bottoms or bottle caps to an assembly device. In some embodiments, in order to improve the processing efficiency of the fire extinguisher, two assembly devices are arranged in parallel. At this time, a feeding conveyor 6 can be arranged on the other side of the lower feeding bin 3. The feeding conveyor 6 is provided with a feeding conveying channel. The feeding conveyor 6 drives the bottle bottoms or bottle caps to move along the feeding conveying channel. When the clamping mechanism 1 receives the material and passes the material level, the accommodating cavity communicates with the feeding conveying channel of the feeding conveyor 6 through the first feeding port or the second feeding port. At this time, the feeding conveying channel communicates with the feeding conveying channel through the accommodating cavity. The bottle bottoms or bottle caps on the loading conveyor 5 can be sent to the feeding conveyor 6 through the clamping mechanism 1. At this time, the feeding conveyor 6 serves as the loading conveyor 5 of the second assembly device. A lower feeding mechanism is also installed at the conveying end of the feeding conveyor 6. The bottle bottoms or bottle caps on the feeding conveyor 6 are diverted and conveyed to the second assembly device by the lower feeding mechanism.

[0028] Because the structure and size of the bottle bottom and the bottle cap of the fire extinguisher are similar before assembly, the downward material adjustment mechanism of the utility model can be used not only for adjusting the bottle bottom to the assembly equipment, but also for adjusting the bottle cap to the assembly equipment.
