Abstract
Description
Technical Field
[0001] The utility model relates to a capping knife mechanism, belonging to the technical field of capping machinery for foods, medicines, etc. Background Art
[0002] In the production of food and medicine, after the container is filled and plugged, the container mouth needs to be covered with an aluminum cap. First, the aluminum cap is placed on the bottle mouth, and then the aluminum cap is rolled to tightly and evenly engage with the groove under the bottle mouth, so that the sealing of the container is more reliable. The existing rolling capping knife cannot rebound or the rebound performance is not increased, resulting in the container mouth being broken after the rolling capping, and the aluminum cap after the rolling capping is uneven, unsightly, not compact, and poorly sealed. Summary of the invention
[0003] The problem to be solved by the utility model is to provide a capping knife structure which has simple structure, low cost, reboundable knife head and can effectively prevent aluminum cap from cutting edge.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A rebound-type capping knife comprises a capping knife head for tightly pressing the lower edge of an aluminum cap of a container bottle mouth under the bottle mouth, a spring for providing a rebound force for the capping knife, a capping knife fixing shaft for fixing the capping knife head and the spring, and a rotating bolt for providing an installation space and a guide for the capping knife head and the capping knife fixing shaft.
[0006] Preferably, the capping knife fixed shaft is arranged in the rotating bolt, the upper end of the capping knife fixed shaft is exposed from the rotating bolt, the end is provided with upper and lower washers, and the spring is arranged between the two washers; the capping knife head is arranged at the lower end of the capping knife fixed shaft.
[0007] More preferably, a bushing is provided between the capping cutter fixed shaft and the rotating bolt.
[0008] More preferably, a spring nut for limiting the position of a washer located above is provided at the upper end of the capping knife fixed shaft.
[0009] More preferably, a bearing is provided between the capping cutter fixed shaft and the capping cutter head.
[0010] Furthermore, a bearing gland screw for limiting the bearing is provided at the bottom of the capping cutter fixed shaft.
[0011] More preferably, a cap is provided above the capping knife fixed shaft, and the edge of the cap extends downward to the outer wall of the rotating bolt. The cap plays the role of aesthetics and dust prevention.
[0012] More preferably, a boss for limiting the rotation of the bolt is provided at the lower portion of the capping cutter fixed shaft, and the capping cutter head is arranged outside the boss.
[0013] Preferably, the rotating bolt is outer-circuited with a large fixed nut.
[0014] Compared with the prior art, the utility model has the advantages of simple structure, low cost, reboundable cutter head and effective prevention of aluminum cover edge cutting. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 The utility model provides a structural schematic diagram of the rebound type capping knife. DETAILED DESCRIPTION
[0016] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.
[0017] Example
[0018] like Figure 1 As shown, a rebound type capping cutter provided by the utility model comprises a capping cutter head 6 for tightly pressing the lower edge of the aluminum cover of the container bottle mouth under the bottle mouth (the chamfer of the upper edge of the capping cutter head 6 matches the chamfer of the lower edge of the container mouth), a spring 3 for providing a rebound force for the capping cutter, a capping cutter fixing shaft 9 for fixing the capping cutter head 6 and the spring 3, and a rotating bolt 8 for providing installation space and guidance for the capping cutter head 6 and the capping cutter fixing shaft 9.
[0019] The capping knife fixed shaft 9 is arranged in the rotating bolt 8, and the rotating bolt 8 is provided with upper and lower bushing installation grooves, in which bushings 4 are respectively inserted. The bushings 4 are fixedly connected to the capping knife fixed shaft 9, serving as a guide for the capping knife fixed shaft 9 and ensuring that the fixed shaft can be lifted and lowered smoothly.
[0020] The capping knife fixed shaft 9 is used as the main shaft of the whole structure, and the middle part is connected with the rotating bolt 8 through the bushing 4 for guiding and positioning. The upper end of the capping knife fixed shaft 9 is exposed from the rotating bolt 8, and the exposed end is provided with upper and lower washers 2, and the spring 3 is arranged between the two washers 2. The upper end of the capping knife fixed shaft 9 is provided with two spring nuts 1 for limiting the washers 2 located above. The lower part of the capping knife fixed shaft 9 is provided with a boss, and the rotating bolt 8 is limited by the boss.
[0021] The capping cutter head 6 is arranged at the lower end of the capping cutter fixed shaft 9 (i.e., the part of the boss), and a pair of upper and lower bearings 10 are provided between the capping cutter fixed shaft 9 and the capping cutter head 6, and an inner and outer spacer sleeves are provided between the two bearings 10. There is a gap between the capping cutter head 6 and the capping cutter fixed shaft 9 to ensure that the capping cutter head 6 can rotate flexibly, and the lower bearing 10 is positioned by a bearing cover screw 11 connected to the bottom of the capping cutter fixed shaft 9.
[0022] A cap 7 is sleeved on the top of the capping knife fixed shaft 9, and the edge of the cap 7 extends downward to the outer wall of the rotating bolt 8. The cap 7 plays the role of aesthetics, dust prevention, and protection from external environmental influences.
[0023] The rotating bolt 8 is provided with a thread on the outside, and the fixing large nut 5 is first inserted into it to fix the assembly of the capping knife on the corresponding capping knife holder; then the cap 7 is inserted into it, and the lower edge of the cap 7 has an internal thread, which cooperates with the fixing large nut 5 to adjust the upper and lower positions of the capping knife on the capping knife holder.
[0024] The spring 3 provides a rebound force for the entire mechanism. When the capping knife is not subjected to downward pressure from the container, the spring 3 stretches, and the boss of the capping knife fixed shaft 9 contacts the lower edge of the rotating bolt 8 to reach the maximum extension length of the spring 3, and the capping knife head 6 is at the highest point. When the capping knife is working, if the container is lower than the set container position, downward pressure will be generated on the capping knife head 6. At this time, the capping knife head 6 drives the capping knife fixed shaft 9 to descend, and the spring 3 is compressed. When the capping work is completed, the capping knife head 6 is separated from the container, and the spring 3 rebounds, driving the capping knife fixed shaft 9 and the capping knife head 6 to reset. This design can provide a stable and reliable rebound force for the overall structure, cooperate with the rotating knife head, effectively prevent the cutting edge of the aluminum cover of the container mouth during work, and the capping is beautiful without corrugated edges, which greatly improves the product qualification rate.

The directions "up", "down", "left", "right", etc. involved are relative positions such as those shown in the accompanying drawings, and are not absolute limitations. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description.
