Description

Technical Field

[0001] This utility model belongs to the technical field of aerosol can refrigerant filling equipment, specifically relating to an aerosol can refrigerant filling, positioning, and stacking mechanism. Background Technology

A nut is fixedly connected to the top right side of the extension plate. A lead screw is threaded into the inner cavity of the nut. A rotating rod is fixedly connected to the end of the lead screw. The end of the rotating rod is rotatably inserted into the end surface of the sliding frame.

[0009] As a further embodiment of this utility model, the two ends of the sliding frame are respectively threaded with fixing bolts, and the ends of the two sets of fixing bolts are respectively threaded through the corresponding side ends of the sliding frame and abut against the surface of the extension plate.

[0010] As a further embodiment of this utility model, the moving part includes a lead screw rotatably connected to a rectangular ring inner cavity, a nut seat threadedly connected to the surface of the lead screw, the bottom of the nut seat being fixedly connected to the top of the extension plate, a servo motor being fixedly mounted at one end of the rectangular ring, and the output shaft of the servo motor being connected to one end of the lead screw via a coupling.

[0016] 3. By setting the fixing bolts, after adjusting the spacing of the receiving cover, the position of the sliding frame is locked by the fixing bolts to prevent the spacing from changing due to vibration or external force during operation, thus ensuring gripping accuracy and stability.

[0030] See appendix Figure 1-3As shown in the figure, an embodiment of the present invention discloses an aerosol can refrigerant filling, positioning, and stacking mechanism, including a gantry frame 100. The gantry frame 100 is installed on the top of one side of the conveyor belt 500 used for conveying aerosol cans. An electric push rod 102 is fixedly installed on the top of the gantry frame 100. A rectangular ring 104 is fixedly connected to the actuating end of the electric push rod 102. One end of the rectangular ring 104 extends above the conveyor belt 500. An extension plate 200 is provided at the bottom of the rectangular ring 104. The inner cavity of the rectangular ring 104 is provided with a moving part for moving the extension plate 200. The extension plate 200 has a limiting hole 209 at its bottom that extends along its length. Several sets of limiting posts 402 are slidably connected to the inner cavity of the limiting hole 209. The bottom of each set of limiting posts 402 is fixedly connected to a receiving cover 400 that is snapped onto the end of the aerosol can. An electromagnet 401 is embedded in the top inner wall of the receiving cover 400. The top of the extension plate 200 is provided with a cross linkage mechanism that adjusts the distance between two adjacent sets of receiving covers 400 according to the diameter of the aerosol can. The top inner wall of the gantry frame 100 is provided with a rotating part for rotating the electric push rod 102.

[0031] The cross linkage mechanism includes a square groove 208 formed on the top of the extension plate 200 and extending along its width. The inner cavity of the square groove 208 is connected to the inner cavity of the limiting hole 209. A sliding block 403 is fixedly connected to the top of each set of limiting posts 402. Each set of sliding blocks 403 is slidably connected to the inner cavity of the square groove 208. Two sets of first connecting rods 300 arranged in a cross configuration are provided on the top of each set of sliding blocks 403. The middle parts of the two sets of first connecting rods 300 on the same side are connected together by a hinge rod 302. The bottom of each set of hinge rods 302 is fixedly connected to the top of the corresponding side sliding block 403. The ends of the two sets of first connecting rods 300 in the same position are rotatably connected to the ends of the adjacent first connecting rods 300 through a transition rod 301. The two sets of first connecting rods on the far left are connected together. The left end of rod 300 is rotatably connected to a second connecting rod 305. The left ends of the two sets of second connecting rods 305 are rotatably connected together by a positioning rod 304. The bottom of the positioning rod 304 is fixedly connected to the top left side of the extension plate 200. The right surface of the extension plate 200 is provided with a pusher for the left-side sliding block 403. Through the setting of the cross linkage mechanism, according to the diameter of the aerosol can, the pusher pushes the sliding frame 202 to the left, thereby the second connecting rod 305 drives the cross-set first connecting rod 300 to move, thereby causing the sliding block 403 connected to the top of the limiting post 402 to slide in the square groove 208, realizing the adjustment of the spacing of the receiving cap 400, thus adapting to the stacking operation of aerosol cans of different specifications. The adjustment process is very simple, improving the continuity and efficiency of production.

[0032] The pusher includes a sliding frame 202 slidably connected to the right end of the extension plate 200. A strip-shaped limiting ring 203 is fixedly connected between the two ends of the sliding frame 202. Two sets of round rods 306 are slidably connected inside the strip-shaped limiting ring 203. The ends of the two sets of round rods 306 are rotatably connected to the corresponding ends of two sets of second connecting rods 305 located on the right side. A nut 207 is fixedly connected to the top right side of the extension plate 200. A lead screw 206 is threaded into the inner cavity of the nut 207. A rotating rod 204 is fixedly connected to the end of the lead screw 206. The end of the rotating rod 204 is rotatably inserted into the end surface of the sliding frame 202. Through the setting of the pusher, the lead screw 206 transmission achieves precise linear displacement control, which is convenient for fine adjustment according to the diameter of the aerosol can. At the same time, the cooperation between the strip-shaped limiting ring 203 and the round rod 306 not only restricts the movement direction of the sliding frame 202, but also allows for angle changes within a certain range, adapting to the motion characteristics of the linkage mechanism.

[0033] The sliding frame 202 has two ends threaded with fixing bolts 201. The ends of the two sets of fixing bolts 201 are threaded through the corresponding side ends of the sliding frame 202 and abut against the surface of the extension plate 200. By setting the fixing bolts 201, after the spacing of the receiving cover 400 is adjusted, the position of the sliding frame 202 is locked by the fixing bolts 201 to prevent the spacing from changing due to vibration or external force during operation, and to ensure gripping accuracy and stability.

[0034] The moving part includes a lead screw 106 rotatably connected to the inner cavity of a rectangular ring 104. A nut seat 105 is threaded onto the surface of the lead screw 106. The bottom of the nut seat 105 is fixedly connected to the top of the extension plate 200. A servo motor 103 is fixedly mounted on one end of the rectangular ring 104. The output shaft of the servo motor 103 is connected to one end of the lead screw 106 via a coupling. Through the setting of the moving part, the nut mechanism of the lead screw 106 driven by the servo motor 103 provides precise lateral positioning capability, enabling the device to accurately align with aerosol cans at different positions.

[0035] The rotating component includes a rotating motor 101 fixedly installed on the top inner wall of the gantry 100. The output axis of the rotating motor 101 passes through the gantry 100 and is fixedly connected to the bottom of the electric push rod 102. By setting the rotating component, the electric push rod 102 and the components below it can be rotated, so that the aerosol can can be switched between different angles to meet the needs of multiple processes such as packaging and labeling.

[0036] A controller 501 is fixedly installed on the surface of the conveyor belt 500. Both the servo motor 103 and the rotary motor 101 are controlled by the controller 501. The controller 501 can control the power supply of the electromagnet 401. A counting sensor 502 is fixedly installed on the bottom right side of the extension plate 200. The signal output terminal of the counting sensor 502 is connected to the signal input terminal of the controller 501 through a wire. The counting sensor 502 is used to detect the number of aerosol cans above the conveyor belt 500. Through the settings of the controller 501, the counting sensor 502 monitors the number of aerosol cans in real time, providing data support for automated control and realizing accurate batch processing. At the same time, the controller 501 coordinates the actions of the servo motor 103, the rotary motor 101 and the electromagnet 401, making the entire operation process smooth and orderly, improving production efficiency and stability.

[0037] In use, according to the diameter of the aerosol can, the lead screw 206 is rotated. The lead screw 206 drives the sliding frame 202 to slide on the right side of the extension plate 200. The sliding frame 202 pushes the second connecting rod 305 through the round rod 306 in the strip-shaped limiting ring 203. The second connecting rod 305 then drives the cross-arranged first connecting rod 300 to move, thereby causing the sliding block 403 connected to the top of the limiting post 402 to slide in the square groove 208, thereby adjusting the spacing of the receiving cover 400. After the adjustment is completed, the fixing bolts 201 at both ends of the sliding frame 202 are tightened to lock the position of the sliding frame 202 and ensure that the spacing of the receiving cover 400 is fixed.

[0038] When the counting sensor 502 counts the aerosol cans, and the number reaches the set value, the controller 501 controls the telescopic end of the electric push rod 102 to move downward, thereby driving the extension plate 200 to move through the rectangular ring 104, so that each set of receiving caps 400 is respectively snapped into the end of the corresponding aerosol can. Subsequently, the controller 501 controls the electromagnet 401 to be energized, and the electromagnet 401 generates magnetic force to firmly attract the aerosol can.

[0039] The controller 501 controls the moving end of the electric push rod 102 to move upward, thereby moving the aerosol can upward. Then, the controller 501 controls the rotary motor 101 to rotate 180 degrees, and at the same time controls the servo motor 103 to rotate, which drives the extension plate 200 to move outward through the nut seat 105, thereby moving the aerosol can towards the palletizing station. Then, the controller controls the moving end of the electric push rod 102 to retract and fall into the palletizing station, and controls the extension end of the push rod to extend. At the same time, the power supply of the electromagnet 401 is disconnected, and the rotary motor 101 is reset to above the conveyor belt 500. At the same time, the counting sensor 502 counts again.

[0040] In summary, this utility model embodiment of a refrigerant filling, positioning, and stacking mechanism for aerosol cans uses a pusher to push the sliding frame 202 to the left according to the diameter of the aerosol can. This causes the second connecting rod 305 to drive the cross-arranged first connecting rod 300 to move, thereby causing the sliding block 403 connected to the top of the limiting post 402 to slide within the square groove 208. This allows for adjustment of the spacing between the receiving caps 400, thus adapting to stacking operations for aerosol cans of different specifications. The adjustment process is very simple, improving the continuity and efficiency of production.

[0041] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention.
