Description

Technical Field

[0001] This utility model belongs to the field of fire extinguisher manufacturing technology, specifically relating to a rotating feeding mechanism for a fire extinguisher cylinder. Background Technology

[0002] In the fire protection equipment manufacturing industry, fire extinguishers are important fire-fighting equipment, and their production efficiency and product quality are directly related to fire safety assurance capabilities. Currently, in the fire extinguisher production process, the assembly and welding of the cylinder and bottom cover usually involves accurately picking up the bottom cover from the conveyor line and firmly fixing it in the predetermined position of the cylinder, followed by welding operations.

[0003] However, the existing production process for picking up the bottom cover often relies on manual operation or simple robotic arm gripping. This method has high labor costs, and the existing technology uses a motor as the part to control rotation, which is prone to damage after long-term use. Replacing the motor is costly and increases the burden on enterprises. Utility Model Content

[0004] The purpose of this invention is to provide a rotating feeding mechanism for fire extinguisher cylinders to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A fire extinguisher cylinder rotary feeding mechanism includes an assembly bracket. A rotating shaft is rotatably mounted on the upper side of the assembly bracket. A rotating block is fixed to the left side of the rotating shaft. A lifting cylinder is fixed to the left side of the rotating block. A slide rail is vertically fixed to the left side of the lifting cylinder. A slider is slidably mounted on the upper side of the slide rail. A circular disk is fixed to the bottom of the slider. The top of the circular disk is drivenly connected to the output end of the lifting cylinder. A suction cup is installed on the inner side of the bottom of the circular disk. A control arm is fixed to the right side of the rotating shaft. A rotary cylinder is hinged to the lower right side of the assembly bracket. One end of the control arm is drivenly connected to the output end of the rotary cylinder.

[0007] The number of suction cups is multiple and evenly distributed around the circumference, and the suction cups are spring-shaped rubber suction cups.

[0008] An upper limit bar is fixed to the upper left side of the assembly bracket, and a lower limit bar fixed to the assembly bracket is installed on the lower side of the rotating shaft. Both the upper limit bar and the lower limit bar are matched with the rotating block.

[0009] Rubber blocks are fixed on both the front and rear sides of the rotating block.

[0010] The control arm tilts downwards from back to front.

[0011] The rotary cylinder, in conjunction with the control arm, drives the rotating shaft to rotate rapidly. Combined with the lifting cylinder, slide rail, and slider, it achieves a combined motion of rapid rotation and lifting of the cylinder, reducing labor costs, shortening component handling cycles, supporting assembly line production, and improving the overall efficiency of the fire extinguisher production line. The combination of the circular disc and suction cups can accommodate different cylinder sizes, enhancing equipment versatility. The fully pneumatic drive scheme of the rotary and lifting cylinders eliminates the risk of electrical sparks, better meeting the explosion-proof safety standards of fire equipment production workshops. Furthermore, the use of industrial standard components such as the rotary cylinder, lifting cylinder, and slide rail results in lower production costs, reducing maintenance and spare parts inventory costs in the long term, thus alleviating the burden on enterprises. Multiple evenly distributed circumferential suction cups ensure a more secure gripping and fixing of the bottom cover, resulting in more precise feeding of workpieces such as the bottom cover. With stability, the spring-shaped rubber suction cup can adapt to the curved surface of the cylinder, avoiding damage to the workpiece surface such as the bottom cover caused by rigid collisions, thereby improving the processing quality of fire extinguisher products; the upper and lower limit bars can work with the rotating cylinder to precisely limit the rotation range of the rotating block, thereby ensuring the feeding accuracy of the equipment and improving the operational stability of the equipment; the rubber buffer blocks on the front and rear sides of the rotating block can reduce the rigid impact of the upper and lower limit bars on the rotating block when the rotating block rotates to the limit position of the upper and lower strokes, which is suitable for high-frequency operation, reduces the equipment failure rate, thereby further extending the service life of the equipment and reducing the operating noise of the mechanism; the tilting control arm can prevent the axis of the control arm from coinciding with the axis of the rotating cylinder during operation, which would cause the mechanism to jam, thereby ensuring that the control arm can rotate smoothly, further ensuring the operational stability and reliability of the equipment.

[0017] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1-3 As shown, a fire extinguisher cylinder rotary feeding mechanism includes an assembly bracket 101. A rotating shaft 102 is rotatably mounted on the upper side of the assembly bracket 101. A rotating block 103 is fixed to the left side of the rotating shaft 102. A lifting cylinder 104 is fixed to the left side of the rotating block 103. A slide rail 105 is vertically fixed to the left side of the lifting cylinder 104. A slider 106 is slidably mounted on the upper side of the slide rail 105. A circular disk 107 is fixed to the bottom of the slider 106. The top of the circular disk 107 is connected to the output end of the lifting cylinder 104. A suction cup 108 is installed on the inner side of the bottom of the circular disk 107. A control arm 109 is fixed to the right side of the rotating shaft 102. A rotary cylinder 110 is hinged to the lower right side of the assembly bracket 101. One end of the control arm 109 is connected to the output end of the rotary cylinder 110.

[0019] In this application, the suction cup 108 is connected to the external air extraction equipment pipeline. When the equipment is working, the lifting cylinder 104 extends and retracts to control the circular disk 107 to move up and down. At this time, the circular disk 107 abuts against the workpiece such as the bottom cover that needs to be clamped. The suction cup 108 adsorbs and fixes the bottom cover. Then, the rotary cylinder 110 converts the linear motion into the rotational motion of the rotating shaft 102 through the hinged control arm 109, rotating the lifting cylinder 104 to the horizontal. Then, the lifting cylinder 104 extends and retracts to drive the bottom cover to the designated position for subsequent welding and other processes.

[0020] The rotary cylinder 110, in conjunction with the control arm 109, drives the rotating shaft 102 to rotate rapidly. Combined with the lifting cylinder 104, slide rail 105, and slider 106, it achieves a combined motion of rapid rotation and lifting of the cylinder. This reduces labor costs, shortens component handling cycles, supports assembly line production, and improves the overall efficiency of the fire extinguisher production line. The combination of the circular disc 107 and the suction cup 108 allows for adaptation to different cylinder specifications, enhancing equipment versatility. The fully pneumatic drive scheme of the rotary cylinder 110 and lifting cylinder 104 eliminates the risk of electrical sparks, better meeting the explosion-proof safety standards of fire equipment production workshops. Furthermore, the use of industrial standard components such as the rotary cylinder 110, lifting cylinder 104, and slide rail 105 results in lower production costs. Long-term use reduces maintenance costs and spare parts inventory costs, helping to alleviate the burden on enterprises.

[0021] There are multiple suction cups 108, which are evenly distributed around the circumference, and the suction cups 108 are spring-shaped rubber suction cups 108.

[0022] Multiple evenly distributed suction cups 108 enable the equipment to grip and fix the bottom cover more firmly, thereby making the feeding of workpieces such as the bottom cover more accurate and stable. The spring-shaped rubber suction cups 108 can adapt to the curved surface of the cylinder, avoiding surface damage to workpieces such as the bottom cover caused by rigid collisions, thereby improving the processing quality of fire extinguisher products.

[0023] An upper limit bar 301 is fixed on the upper left side of the assembly bracket 101, and a lower limit bar 302 fixed to the assembly bracket 101 is installed on the lower side of the rotating shaft 102. Both the upper limit bar 301 and the lower limit bar 302 are matched with the rotating block 103.

[0024] The upper limit bar 301 and the lower limit bar 302 can work together with the rotating cylinder to precisely limit the rotation range of the rotating block 103, thereby ensuring the feeding accuracy of the equipment and improving the operational stability of the equipment.

[0025] Rubber blocks 401 are fixed on the front and rear sides of the rotating block 103.

[0026] The rubber buffer blocks on the front and rear sides of the rotating block 103 can reduce the rigid impact of the upper limit bar 301 and the lower limit bar 302 on the rotating block 103 when the rotating block 103 rotates to the limit position of the upper and lower strokes. This is suitable for high-frequency operation, reduces the equipment failure rate, and further extends the service life of the equipment, as well as reduces the operating noise of the mechanism.

[0027] The control arm 109 tilts downwards from back to front.

[0028] The tilted control arm 109 can prevent the axis of the control arm 109 from coinciding with the axis of the rotary cylinder 110 during operation, thus preventing the mechanism from jamming and ensuring that the control arm 109 can rotate smoothly, further guaranteeing the stability and reliability of the equipment operation.

[0029] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
