DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] The aerosol can is divided into a can body and a cover body. The cover body is transported to the lower end of the chuck 26, and the chuck 26 grabs a cover body. At the same time, the transfer mechanism 23 rotates the clamping mechanism 22 to the conveying disc 12, and the clamping mechanism 22 clamps the can body in the driving groove 121. The transfer mechanism 23 then transfers the clamping mechanism 22 to the U-shaped mounting plate 21. At this time, the can body is below the cover body, and the clamping mechanism 22 releases the clamping of the can body, and the can body falls on the first fixing structure 24. The first fixing structure 24 fixes the can body while making the axis of the fixed can body and the axis of the cover body collinear. Then the lifting drive 27 drives the chuck 26 to move downward until the cover body is pressed against the upper end of the can body, and the rotary drive mechanism 25 works, the can body rotates, and the can body moves toward the cover body, so that the can body and the cover body are connected. By setting the first fixing structure 24, the first fixing structure 24 can make the axis of the can body and the axis of the cover body collinear, thereby improving the qualified rate after the can body and the cover body are connected.

[0040] Reference Figure 3 , Figure 4 and Figure 5As shown: the first fixing structure 24 includes a U-shaped frame 241 and a self-clamping structure 242; the opening of the U-shaped frame 241 faces upward, and the axis of the U-shaped frame 241 is collinear with the axis of the chuck 26, so that the axis of the tank body fixed by the self-clamping structure 242 is collinear with the axis of the cover body; the self-clamping structure 242 is arranged at the lower end of the U-shaped frame 241, and the self-clamping structure 242 includes two second arc-shaped clamping plates 2421, and the two second arc-shaped clamping plates 2421 can fix the axis of the tank body to be collinear with the axis of the cover body under the action of the tank body's own gravity, and the self-clamping structure 242 also includes a supporting plate 2422, a second guide column 2423, a second spring 2424, two driving plates 2425, two limiting shafts 2426, two first rectangular frames 2427 and two second rubber pads 2428, the axis of the supporting plate 2422 is collinear with the axis of the chuck 26, and the second guide column 242 3 vertically passes through the lower end of the U-shaped frame 241, and the second guide column 2423 can move up and down, the second spring 2424 is sleeved on the second guide column 2423, the two driving plates 2425 are respectively arranged on both sides of the second guide column 2423, the two ends of the driving plate 2425 are respectively axially connected with the second guide column 2423 and the second arc clamping plate 2421, the two limiting shafts 2426 are respectively installed in the middle of the two driving plates 2425, the two first rectangular frames 2427 are respectively arranged on both sides of the second guide column 2423, the first rectangular frame 2427 is symmetrically provided with two second strip grooves, the two ends of the limiting shaft 2426 are respectively slidably arranged in the two second strip grooves, the two second rubber pads 2428 are respectively arranged on the inner sides of the two second arc clamping plates 2421, and the second rubber pads 2428 can prevent the second arc clamping plates 2421 from scratching the surface of the tank body.

[0041] After the tank body is released by the clamping mechanism 22, the tank body falls on the supporting plate 2422, and the supporting plate 2422 moves downward due to the gravity of the tank body. The supporting plate 2422 pushes the second guide column 2423 to move, the second spring 2424 is compressed, and the second guide column 2423 drives the driving plate 2425 to move, and the driving plate 2425 drives the limiting shaft 2426 to slide along the second strip groove. At the same time, the driving plate 2425 drives the second arc clamping plate 2421 to move toward the tank body, and the two second arc clamping plates 2421 move toward the tank body from both ends of the tank body at the same time. After one second arc clamping plate 2421 contacts the tank body first, it pushes the tank body to move toward the other second arc clamping plate 2421 until the two second arc clamping plates 2421 are both in contact with the tank body, so that the axis of the tank body is in line with the axis of the cover body, thereby achieving the adjustment and fixation of the position of the tank body without using a driving device.

[0042] Reference Figure 4 and Figure 5As shown: the first fixed structure 24 also includes a first auxiliary structure 243, the first auxiliary structure 243 has two, the two first auxiliary structures 243 are respectively arranged at the two ends of the U-shaped frame 241, the two first auxiliary structures 243 are respectively used to control the movement posture of the two second arc-shaped plates, the first auxiliary structure 243 includes a second rectangular frame 2431, a third guide column 2432, a slider 2433, a third spring 2434 and a telescopic column 2435, the second rectangular frame 2431 is connected to the U-shaped frame 241, the third guide column 2432 is vertically arranged, and the third guide column 243 2 are respectively connected to the two ends of the second rectangular frame 2431, the slider 2433 is slidably set on the third guide column 2432, the third spring 2434 is sleeved on the third guide column 2432, one end of the third spring 2434 is connected to the slider 2433, and the other end of the third spring 2434 is connected to the second rectangular frame 2431, the third spring 2434 is used to apply a force to the slider 2433 so that the slider 2433 can be reset, one end of the telescopic column 2435 is connected to the slider 2433, and the other end of the telescopic column 2435 is connected to the second arc clamping plate 2421.

[0043] The state of the second arc-shaped clamping plate 2421 is not controlled. When the two second arc-shaped clamping plates 2421 clamp the tank body, the outer surface of the tank body may be damaged. By setting the first auxiliary structure 243, the telescopic column 2435 connects the second arc-shaped clamping plate 2421 and the slider 2433, so that the second arc-shaped clamping plate 2421 is in a horizontal state. When the driving plate 2425 moves, the slider 2433 moves along the third guide column 2432, so that the axis of the second arc-shaped clamping plate 2421 is always parallel to the axis of the tank body, so that when the two second arc-shaped clamping plates 2421 clamp the tank body, the second rubber pad 2428 is between the second arc-shaped clamping plate 2421 and the tank body, avoiding damage to the surface of the tank body.

[0044] Reference Figure 4 and Figure 6 As shown: the first fixed structure 24 also includes a second auxiliary structure 244, which is arranged at the upper end of the U-shaped frame 241. The second auxiliary structure 244 is used to limit the movement range of the upper end of the U-shaped frame 241. The second auxiliary structure 244 includes a limiting cylinder 2441, an annular frame 2442 and a plurality of first rollers 2443. The axis of the limiting cylinder 2441 is colinear with the axis of the chuck 26. One end of the limiting cylinder 2441 is connected to the U-shaped mounting plate 21. The annular frame 2442 is sleeved on the limiting cylinder 2441. The two ends of the annular frame 2442 are respectively connected to the two ends of the U-shaped frame 241. A plurality of first rollers 2443 are arranged in an annular array on the annular frame 2442. The first rollers 2443 are tangent to the limiting cylinder 2441.

[0045] When the U-shaped frame 241 rotates, the upper end of the U-shaped frame 241 is affected by the centrifugal force and will swing to a certain extent. The swing of the U-shaped frame 241 will cause deviation between the tank body and the cover body. By setting the second auxiliary structure 244, the U-shaped frame 241 drives the annular frame 2442 to rotate, and the annular frame 2442 rotates around the limiting cylinder 2441. The first roller 2443 can reduce the friction between the annular frame 2442 and the limiting cylinder 2441. The limiting cylinder 2441 can prevent the annular frame 2442 from swinging. The annular frame 2442 therefore limits the swing of the upper end of the U-shaped frame 241, thereby preventing the tank body from swinging following the U-shaped frame 241.

[0046] Reference Figure 3 and Figure 7 As shown: the rotary drive mechanism 25 includes a rotary driver 251, a transmission plate 252, a fourth guide column 253 and a transmission connection block 254; the rotary driver 251 is connected to the U-shaped frame 241, and the output shaft of the rotary driver 251 extends into the interior of the U-shaped frame 241; the middle part of the transmission plate 252 is connected to the output shaft of the rotary driver 251; there are two fourth guide columns 253, which are respectively arranged at both ends of the transmission plate 252, and one end of the fourth guide column 253 is connected to the transmission plate 252; there are two transmission connection blocks 254, which are respectively arranged on both sides of the U-shaped frame 241, and the U-shaped frame 241 is installed on the U-shaped frame 241, and the other end of the fourth guide column 253 passes through the transmission connection block 254 upward.

[0047] When the tank body is connected to the cover body, the tank body will drive the U-shaped frame 241 to move upward toward the cover body. By setting a rotation driver 251, a transmission plate 252, a fourth guide column 253 and a transmission connecting block 254, the rotation driver 251 drives the transmission plate 252 to rotate, and the transmission plate 252 drives the two fourth guide columns 253 to rotate. The two fourth guide columns 253 drive the U-shaped frame 241 to move through the two transmission connecting blocks 254. When the U-shaped frame 241 moves upward, the U-shaped frame 241 drives the transmission connecting block 254 to move upward along the two fourth guide columns 253, thereby realizing that the U-shaped frame 241 can both rotate and move upward.

[0048] Reference Figure 3 and Figure 8As shown: the capping device 2 also includes a second fixing structure 28, which is used to fix the open end of the can body. The second fixing structure 28 includes an annular mounting plate 281 and two second clamping arms 282. The annular mounting plate 281 is coaxially arranged with the chuck 26, and the annular mounting plate 281 is fixedly connected with the chuck 26. The two second clamping arms 282 are respectively arranged on both sides of the annular mounting plate 281. The second clamping arm 282 includes an L-shaped connecting plate 2821, a second linear driver 2822, an arc-shaped mounting plate 2823 and a plurality of second rollers 2824. One end of the L-shaped connecting plate 2821 is connected with the chuck 26, the second linear driver 2822 is connected with the L-shaped connecting plate 2821, the arc-shaped mounting plate 2823 is connected with the output end of the second linear driver 2822, and a plurality of second rollers 2824 are arranged on the arc-shaped mounting plate 2823, and the second rollers 2824 are tangent to the can body.

[0049] The upper end of the tank body is not fixed, and the tank body will swing when it rotates. By setting the second fixed structure 28, after the cover body abuts against the tank body, the two second linear drivers 2822 work simultaneously, and the second linear drivers 2822 push the arc-shaped mounting plate 2823 to move toward the tank body until a plurality of second rollers 2824 abut against the tank body. Since the second fixed structure 28 will not rotate with the U-shaped frame 241, the tank body drives the plurality of second rollers 2824 to rotate when it rotates, reducing the friction between the tank body and the arc-shaped mounting plate 2823, thereby realizing the posture control of the upper end of the tank body during the rotation process, and improving the success rate of the connection between the tank body and the cover body.

[0051] The first driver 223 first drives the bidirectional screw 222 to rotate, and the bidirectional screw 222 drives the two transmission clamps 2241 to move away from each other. The transfer mechanism 23 pushes the two transmission clamps 2241 to be inserted between the two conveying discs 12. The first driver 223 drives the bidirectional screw 222 to rotate, and the bidirectional screw 222 drives the two transmission clamps 2241 to move closer to each other. The two transmission clamps 2241 drive the four first arc clamps 2242 to move toward the tank body. The four first arc clamps 2242 clamp the tank body, thereby clamping the tank body.

[0052] Reference Fig. 9 and Fig.10 As shown, the clamping mechanism 22 further includes a pressure detector 225, which is used to detect the force of the first clamping arm 224 clamping the can body. There are four pressure detectors 225, and the four pressure detectors 225 correspond to the four first guide pillars 2243 respectively.

[0053] After the tank body and the cover body are connected, the lifting driver 27 drives the chuck 26 to move upward, and the chuck 26 drives the tank body to move upward, and the tank body is disengaged from the first fixed structure 24, and the U-shaped frame 241 and the self-clamping structure 242 are reset. At the same time, the second fixed structure 28 is separated from the tank body. At this time, only the cover body is connected to the chuck 26, and then the transfer mechanism 23 pushes the clamping mechanism 22 to the tank body, and the two first clamping arms 224 clamp the tank body, and the four first arc-shaped clamping plates 2242 are pressed against the tank body. If the axis of the tank body is collinear with the axis of the cover body, the detection values ​​of the four pressure detectors 225 are the same. If the detection value of the pressure detector 225 is abnormal, it means that the tank body has a deviation, so as to distinguish whether the cover body and the tank body are qualified after connection.

[0054] Reference Figure 1 and Fig.11 As shown: the transfer mechanism 23 includes a storage box 231, a first linear driver 232 and a first connecting block 233; one end of the storage box 231 is connected to the U-shaped mounting, and a first strip groove is provided on the surface of the storage box 231; the first linear driver 232 is arranged on the storage box 231; one end of the first connecting block 233 is connected to the first linear driver 232, and the other end of the first connecting block 233 passes through the first strip groove and is connected to the clamping mechanism 22.

[0055] The first linear drive 232 drives the first connecting block 233 to move, the first connecting block 233 drives the base 221 to move, the first clamping arm 224 brings the tank body into the U-shaped mounting plate 21, and the first clamping arm 224 releases the clamping of the tank body. The first clamping arm 224 will hinder the rotation of the U-shaped frame 241, so the first linear drive 232 drives the first connecting block 233 to continue to move, the first connecting block 233 drives the base 221 to move toward the storage box 231, and the clamping mechanism 22 is stored in the storage box 231, thereby avoiding the first clamping arm 224 from hindering the movement of the U-shaped frame 241.

[0056] A capping method for a conveying and capping system of an aerosol can comprises the following steps:

[0057] S1, the conveying track 11 conveys the can body to the conveying tray 12, and the conveying tray 12 drives the can body to move;

[0058] S2, the transfer mechanism 23 pushes the clamping mechanism 22 to the conveying plate 12, the clamping mechanism 22 clamps the can body, and the transfer mechanism 23 then transfers the can body to the inside of the U-shaped mounting plate 21;

[0059] S3, the clamping mechanism 22 removes the force acting on the can body, and the can body falls on the first fixing structure 24, and the first fixing structure 24 makes the axis of the can body and the axis of the cover body collinear and fixes the can body;

[0060] S4, the rotation drive mechanism 25 drives the first fixed structure 24 to rotate, and the first fixed structure 24 drives the can body to rotate, so that the axis of the can body and the axis of the cover body are collinearly connected, thereby improving the qualified rate of the capping.

[0061] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
