Abstract
Description
Technical Field
[0001] This utility model relates to the field of food and pharmaceutical packaging equipment technology, specifically to a capping locking device and a filling capping system. Background Technology
[0002] Existing capping machines typically use a cam to drive two semi-circular jaws to open and close, capping glass and plastic bottles. This method is only suitable for capping caps with a single indentation. Uneven force is applied to the cap during the capping process, resulting in poor sealing. This is especially problematic for aseptic three-piece spray kits (including the bottle, pump head, and push button). The bottle has a neck groove at the top, and the pump head has a cap on its periphery. The cap needs to be folded inward and tightened into the neck groove of the bottle. Existing capping machines cannot meet these requirements.
[0003] Due to the unique structure of the aseptic three-piece spray kit (including the bottle, pump head, and push button), current assembly and production are generally carried out manually, which is labor-intensive and has low production efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a capping locking device and filling capping system that provides good uniformity of force during the capping process and good sealing performance after capping, and can meet the capping requirements of aseptic three-piece spray kit.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A capping locking device includes a mounting base, a pressure sleeve, a capping head, and a capping sleeve. The pressure head is located at the bottom of the mounting base. The top of the capping sleeve is fixed on the mounting base and sleeved over the pressure head. The capping sleeve has multiple spacer grooves arranged around a center, extending to the bottom of the capping sleeve. Adjacent spacer grooves form a capping body that can swing inward and outward. The pressure sleeve is movably sleeved over each capping sleeve. The mounting base is provided with a capping driving mechanism, which is connected to the pressure sleeve and is used to drive the pressure sleeve to move and push the capping body to swing inward.
[0007] As a further improvement to the above technical solution:
[0008] The bottom inner side of the cap body is provided with an inwardly convex cap portion and the outer side is provided with an outwardly convex pressure receiving portion. The inner side of the pressure sleeve is provided with a pushing surface that cooperates with the pressure receiving portion.
[0009] The extrusion surface is a conical surface, and the outer side of the pressure-bearing part is adapted to the extrusion surface.
[0010] The capping drive mechanism includes a telescopic drive component and a linkage assembly. The telescopic drive component is mounted on a mounting base and connected to the pressure sleeve through the linkage assembly.
[0011] The telescopic drive component is a pneumatic cylinder, hydraulic cylinder, or electric cylinder.
[0012] The pressure head is an elastic pressure head.
[0013] The capping locking device also includes a lifting mechanism, and the mounting base is disposed on the lifting mechanism.
[0014] A filling and capping system includes a conveyor line and a bottle feeding device, a front weighing device, a filling device, a rear weighing device, a pump head device, the capping locking device, a push button device, and a waste rejection device arranged sequentially along the conveyor line.
[0015] As a further improvement to the above technical solution:
[0016] An air washing device and a pre-nitrogen filling device are sequentially provided between the front weighing device and the filling device, and a post-nitrogen filling device is provided between the rear weighing device and the pump head device.
[0017] The bottle feeding device includes a bottle unscrambling mechanism and a bottle feeding mechanism, wherein the bottle feeding mechanism is located between the bottle unscrambling mechanism and the conveyor line.
[0018] Compared with the prior art, the advantages of this utility model are:
[0019] This utility model discloses a capping and locking device. During capping, the cap body extends into the capping sleeve, the capping head abuts against the top surface of the cap body, and the capping drive mechanism drives the pressure sleeve to move, pushing the capping body to swing inward to squeeze the bottom edge of the cap body to achieve capping. Multiple capping bodies arranged at central intervals in the capping sleeves work together to achieve capping, with two opposing semi-circular grippers achieving the same effect. The cap body experiences good uniform force during capping, resulting in good sealing after capping, thus meeting the capping requirements for aseptic three-piece spray kits.
[0020] The filling and capping system of this utility model has all the advantages of the capping and locking device. Attached Figure Description

[0036] Example 1:
[0037] Figures 1 to 4 This invention illustrates an embodiment of the cap-locking device. The cap-locking device of this embodiment includes a mounting base 1, a pressure sleeve 2, a cap-locking head 3, and a cap-locking sleeve 4. The pressure sleeve 3 is located at the bottom of the mounting base 1. The top of the cap-locking sleeve 4 is fixed on the mounting base 1 and sleeved over the pressure sleeve 3. The cap-locking sleeve 4 has multiple spacer grooves 41 arranged around the center, which extend to the bottom of the cap-locking sleeve 4. Adjacent spacer grooves 41 form a cap-locking body 42 that can swing inward and outward. The pressure sleeve 2 is movably sleeved over each cap-locking sleeve 4. The mounting base 1 is provided with a cap-locking drive mechanism 5, which is connected to the pressure sleeve 2 and is used to drive the pressure sleeve 2 to move (moving along the axial direction of the cap-locking sleeve 4) to push the cap-locking body 42 to swing inward and lock the cap.
[0038] During capping, the cap extends into the capping sleeve 4, the capping head 3 abuts against the top surface of the cap, and the capping drive mechanism 5 drives the pressure sleeve 2 to move, pushing the capping body 42 inward to squeeze the bottom edge of the cap to achieve capping. Multiple capping bodies 42, arranged at central intervals in the capping sleeves 4, work together to achieve capping, with the capping achieved by the relative two semi-circular grippers. The cap experiences good uniform force during the capping process, resulting in good sealing after capping, thus meeting the capping requirements for aseptic three-piece spray kits.
[0039] Furthermore, in this embodiment, the inner side of the bottom of the capping body 42 is provided with an inwardly protruding capping portion 421, and the outer side is provided with an outwardly protruding pressure receiving portion 422. The inner side of the pressure sleeve 2 is provided with a pushing surface 21 that cooperates with the pressure receiving portion 422. Thus, as Figure 4 As shown, when the pressure sleeve 2 is relative to the bottle body 18 (e.g.) Figure 6As shown, when moving downwards, the extrusion surface 21 pushes the pressure-receiving part 422 to cause the capping body 42 to swing inwards. During the inward swing of the capping body 42, the capping part 421 squeezes the bottom edge of the capping body to achieve capping. When the pressure sleeve 2 moves upwards relative to the bottle body 18, the extrusion surface 21 disengages from the pressure-receiving part 422, and the capping body 42 swings outwards to reset under the elastic reset action.
[0040] Furthermore, such as Figure 2 As shown, in this embodiment, the extrusion surface 21 is a conical surface, and the outer surface of the pressure-bearing part 422 is adapted to the extrusion surface 21. The extrusion effect is good.
[0041] Furthermore, such as Figure 2 As shown, in this embodiment, the capping drive mechanism 5 includes a telescopic drive component 51 and a linkage component 52. The telescopic drive component 51 is mounted on the mounting base 1 and connected to the pressure sleeve 2 via the linkage component 52. The telescopic drive component 51 telescopically moves, driving the pressure sleeve 2 to reciprocate through the linkage component 52, thereby achieving capping and cap release.
[0042] Furthermore, in this embodiment, the telescopic drive component 51 is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.
[0043] Furthermore, in this embodiment, the capping head 3 is an elastic capping head to avoid damaging the cap.
[0044] Furthermore, in this embodiment, the capping and locking device also includes a lifting mechanism, and the mounting base 1 is disposed on the lifting mechanism. The mounting base 1 is disposed on the lifting mechanism and can move up and down with the lifting mechanism to meet the capping and locking device's requirement for each cap to be pressed down.
[0045] This utility model relates to a capping and locking device for capping aseptic three-piece spray kits, such as... Figures 7 to 9 As shown, the device includes a bottle body 18, a pump head 19, and a push button 101. The top of the bottle body 18 has a neck ring groove 181, and the periphery of the pump head 19 has a bottle cap 191 (also called a cap). This capping and locking device folds the bottom of the bottle cap 191 inward and tightens it into the neck ring groove 181 of the bottle body 18.
[0046] Example 1:
[0047] Figure 5 This invention illustrates one embodiment of the filling and capping system of the present invention. The filling and capping system of this embodiment includes a conveyor line 6 and a bottle feeding device 7, a front weighing device 8, a filling device 9, a rear weighing device 11, a pump head device 12, a capping locking device of Embodiment 1, a push button device 13, and a waste rejection device 14 arranged sequentially along the conveyor line 6.
[0048] The bottle feeding device 7 is used to supply the bottle body 18 to the conveyor line 6. The conveyor line 6 conveys the bottle body 18 sequentially to the front weighing device 8, the filling device 9, the rear weighing device 11, and the pump head device 12. The front weighing device 8 performs a pre-weighing of the bottle body 18 (empty bottle weighing), the filling device 9 fills the bottle body 18, and the rear weighing device 11 performs a post-weighing of the bottle body 18 (post-filling weighing). The pump head device 12 adds a pump head 19 to the top of the bottle body 18. The capping and locking device folds the bottom of the cap 191 inward and tightens it into the neck ring groove 181 of the bottle body 18. The push button device 13 is used to add the push button 101 to the bottle body 18 and cover the top of the pump head 19.
[0049] This filling and capping system includes a capping locking device, which has all the advantages of a capping locking device.
[0050] Furthermore, in this embodiment, a gas washing device 15 and a front nitrogen filling device 16 are sequentially provided between the front weighing device 8 and the filling device 9, and a rear nitrogen filling device 17 is provided between the rear weighing device 11 and the pump head device 12. The gas washing device 15 is used to gas wash the bottle body 18. The front nitrogen filling device 16 and the rear nitrogen filling device 17 are used to fill the bottle body 18 with nitrogen.
[0051] Furthermore, in this embodiment, the bottle feeding device 7 includes a bottle sorting mechanism 71 and a bottle feeding mechanism 72, with the bottle feeding mechanism 72 located between the bottle sorting mechanism 71 and the conveyor line 6.
