[0002] In the packaging machinery industry of beverages, liquor and the like, the capping structure of liquor bottle caps is complex and the capping precision is relatively high. The inside of the liquor bottle cap has requirements for guaranteeing sealing and anti-theft and anti-rotation structures, and the capping head cannot adopt the scraping mode to take the cap; in addition, most of the liquor cap bodies are mainly shaped, for example, the head is large and the body is small, which further increases the difficulty of taking the cap. In addition, the outer surface of the liquor cap body has high requirements for the factory specifications and cannot be ground, so the materials for taking and capping the cap should be carefully selected.

The pressing block assembly 7 comprises a pressing block 701, a third elastic member 702 and a pressing cover head 703; the pressing block 701 is circumferentially uniformly provided with a flange 7011, the flange 7011 is installed in the positioning clamping groove 6004 below the pressure claw base 6 and is fixed with the pressure claw base 6; the pressing cover head 703 is movably arranged in the pressing block 701 and is provided with a key groove to limit the circumferential rotation, and it can move axially relative to the pressing block 701; the third elastic member 702 is a compression spring, which is arranged between the pressing block 701 and the pressing cover head 703.

For example, the structure of the clamp jaw in the case can be designed as an arc, thereby better adapting to special-shaped bottle caps, especially the large-head small-body liquor bottle cap.

[0009] When the pressing cover plunger and the ejector rod descend together, the pressing cover plunger can drive the pressing block assembly to approach the bottle cap, and the first cam stroke is greater than the second cam stroke, so that the ejector rod moves upward relative to the pressing cover plunger, thereby controlling the connecting rod clamp jaw mechanism to close and clamp the bottle cap; thereafter, with the continuous descent of the pressing cover plunger, the pressing block assembly completes the capping work, and forces the pressure claw base to move upward, thereby forcing the connecting rod clamp jaw mechanism to open until the bottle cap is taken away; finally, the pressing cover plunger and the ejector rod ascend together, and the ejector rod moves downward relative to the pressing cover plunger, thereby causing the connecting rod clamp jaw mechanism to continuously open and wait for the next descent.

DETAILED DESCRIPTION

[0012] ​​In order to clearly illustrate the technical features of the application, the following will be described in detail through specific embodiments and in conjunction with the accompanying drawings.

[0013] Figure 1 、 Figure 2 A schematic diagram showing a part of the structure of a high-speed capping structure, the high-speed capping structure having a bottle feeding star wheel B1, a capping star wheel B2, a cap slide B3, and a bottle discharging star wheel B4, wherein the capping star wheel B2 is one of the components of a capping machine, and is fixedly connected to a central rotating shaft of the capping machine, and the capping machine further comprises a first cam A1, a second cam A2, and a mounting base B5, wherein the first cam A1 and the second cam A2 are fixed on a frame of the capping machine, the mounting base B5 is fixed axially relative to the capping machine, and is coaxial and rotates at the same speed as the capping star wheel B2 circumferentially relative to the capping machine around a central shaft K. Figure 2 、 Figure 3 A schematic diagram showing a capping head mounting and working mode, the capping head is arranged at a fixed interval along the outer circumferential circle of the capping star wheel of the capping machine, the fixed seat 1 is fixedly mounted on the mounting base B5, and the first roller 301 is distributed and attached to the track surface of the first cam A1.

[0014] Referring to Figure 1 and Figure 2, the glass bottle or the like filled with liquid through the filling valve (not shown) is transferred to the capping star wheel B2, the capping star wheel B2 rotates clockwise to rotate the glass bottle or the like, the capping head moves from the rising stage to the horizontal capping stage of the first cam A1, and the second roller 501 drives the guide seat 5 to move downward relative to the capping head 100 until the guide block 10 touches the lowermost edge of the waist-shaped through hole 2001 of the capping plunger 2, at this time the top rod 4 transmits the downward stroke to the connecting rod jaw mechanism 12, according to the principle of the planar connecting rod mechanism, it is known that the first connecting rod 121 moves inward relative to the capping head, referring to the drawings, the articulation point of the first connecting rod 121 and the connecting piece 8 moves downward, at this time the articulation point of the first connecting rod 121 and the second connecting rod 122 moves toward the central axis L, thereby driving the second connecting rod 122 to rotate toward the axis L relative to the pin hole of the pressing jaw seat 6, and then the jaw 123 rotates outward relative to the pin hole to open to the maximum angle. At this time, the lowermost edge of the capping head is higher than the bottle cap P; when the bottle cap P is accurately transferred to the position directly below the capping head, the capping head moves downward relative to the cap body under the action of the first cam A1, thereby lowering the opened jaw 123 to the appropriate position of the bottle cap P, at the same time, under the relative motion restriction of the second roller 501 and the second cam A2, the top rod 4 is subjected to the upward force from the second elastic member 15 to move the guide seat 5 upward relative to the capping head until the guide block 10 touches the uppermost edge of the waist-shaped through hole 2001 of the capping plunger 2, according to the principle of the planar connecting rod mechanism, it is known that the first connecting rod 121 moves outward relative to the capping head 100, thereby driving the second connecting rod 122 to rotate outward relative to the pin hole of the pressing jaw seat 6, and then the jaw 123 rotates inward relative to the pin hole to close to the minimum angle and grip the bottle cap P.

[0015] After the cap is taken, the capping head continues to move downward under the action of the first cam A1 and clamps the bottle cap P on the bottle mouth of the glass bottle or the like. The capping head 100 continues to move downward and presses the bottle cap P on the bottle mouth of the container under the action of the pressing block assembly 7, at the same time, the second connecting rod 122 moves upward in a plane under the action of the upward movement of the pressing jaw seat 6 during capping and the position of the fixed articulation point of the second connecting rod 122 and the pressing jaw seat 6 moves upward, thereby pushing the articulation point of the first connecting rod 121 and the second connecting rod 122 to rotate upward around the articulation point center of the first connecting rod 121 and the connecting piece 8, and forcing the jaw 123 to open outward. When the capping is completed, the top rod 4 is driven downward by the height difference of the two cams to complete the continuous opening of the jaw. This is to prevent the jaw from tightening the bottle cap P after capping, causing the capping head 100 to lift the whole bottle to the air, and avoiding the loss caused by the falling of the bottle after the jaw is loosened.

[0016] Finally, the capped glass bottle or other container is sent to the bottle star wheel B4 by the capping star wheel B2, and then is sent to the next process by the conveying belt (not shown).

Thus, the first roller 301 and the second roller 501 can perform lifting motion in the same direction at the same time, and relative linear motion is generated due to the difference in the movement stroke, further controlling the closing or opening of the connecting rod clamping jaw mechanism 12.

[0019] The capping head further comprises a fixed seat 1, a capping plunger 2, a guide block 10, a jacking rod 4, a first elastic member 14, a second elastic member 15, a guide seat 5 and a clamping jaw seat 6; The fixed seat 1 is fixedly installed on the mounting seat B5, the capping plunger 2 is movably arranged in the fixed seat 1, and a lubrication-free bearing is arranged between the capping plunger 2 and the fixed seat 1, the top end of the capping plunger 2 is connected with the first roller 301 and moves up and down with the first roller 301, the lower part of the capping plunger 2 is fixedly installed with a spring seat 13 and the bottom end is fixedly connected with a baffle 9, the clamping jaw seat 6 is movably sleeved on the bottom end of the capping plunger 2 and is between the spring seat 13 and the baffle 9, the first elastic member 14 is arranged between the spring seat 13 and the clamping jaw seat 6, and the clamping jaw seat 6 is fixedly connected with the pressing block assembly 7 through a plurality of cantilever arms; thus, when the clamping jaw seat 6 receives the upward force transmitted by the pressing block assembly 7, it can move upward relative to the capping plunger 2, and when the force disappears, it can be reset downward under the action of the first elastic member 14 and the self weight; The top rod 4 is movably arranged in the pressure cover plunger 2, and a lubrication-free bearing is arranged between the pressure cover plunger 2 and the top rod 4.
