Description

Technical Field

[0001] The utility model relates to the technical field of vacuum capping machines, in particular to a double-station feeding structure of a capping machine. Background Art

[0002] Vacuum capping machines are used for vacuum capping of tinplate glass bottles. They are widely used in bottled products. By sealing the bottles in a vacuum chamber, they ensure that no air is trapped inside the bottles, thereby extending the shelf life of the products inside. Existing vacuum capping machines operate by placing the bottles into the vacuum chamber, sealing and evacuating them, then capping them. Finally, the bottles are removed from the vacuum chamber and moved on to the next tool.

[0003] Existing vacuum capping machines typically consist of a vacuum capping structure, a mounting base that secures the bottle body, and a dual-station loading mechanism that moves the bottle body mounting base to a designated position. The dual-station loading mechanism includes a mounting frame, a telescopic cylinder, guide rails, a slide, and a mounting base. During operation, the telescopic cylinder operates to move the two bottle body mounting bases on the mounting base below the vacuum capping structure. However, during use, it was discovered that the slides and guide rods experience sliding friction, requiring frequent maintenance and replacement. This is not only costly, but also inconvenient due to the layout and installation of the guide rods, slide, and mounting base. Utility Model Content

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0040] Refer to the attached Figure 1 -Attached Figure 5As shown, a double-station loading structure of a capping machine includes:

[0041] There are two fixing plates 1 and a threaded hole 11 is provided on the side thereof;

[0042] There is one telescopic cylinder 2 and it is horizontally arranged on one of the fixed plates 1;

[0043] There are two guide rods 3 and they are horizontally arranged between the two fixing plates 1. The two ends of the guide rods 3 are provided with threaded holes 31 that match the threaded holes 11. The threaded holes 11 and the threaded holes 31 are used to receive bolts together to bolt the guide rods 3 to the fixing plates 1.

[0044] There are four slides 4, and every two slides 4 are rolled and sleeved on the outside of a guide rod 3, and the top of the slide 4 is provided with a threaded hole 411;

[0045] There is one mounting seat 5 disposed on the top of the four slides 4. The mounting seat 5 is provided with a fourth threaded hole 51 that matches the third threaded hole 411. The third threaded hole 411 and the fourth threaded hole 51 are used to receive a bolt to connect the mounting seat 5 to the slide 4. The mounting seat 5 is also provided with a fifth threaded hole 52 for connecting to the bottle body fixing seat with a bolt.

[0046] The connecting seat 6 has a bolt connected to the bottom of the mounting seat 5 and is connected to the telescopic end of the telescopic cylinder 2, so that the operation of the telescopic cylinder 2 causes the connecting seat 6 to move horizontally, and finally causes the two bottle body fixing seats placed on the mounting seat 5 to move.

[0047] During the specific implementation of this embodiment, the slide 4 and the guide rod 3 have rolling friction, which reduces the friction between the two, thereby increasing the service life of the slide 4 and the guide rod 3 and reducing maintenance costs; in addition, the guide rod 3 and the fixed plate 1 are connected by bolts, and the slide 4 and the mounting seat 5 are connected by bolts. When replacement operations are required, the operation is convenient and the disassembly and assembly efficiency is improved.

[0048] In the above embodiment, the structure of the slide 4 is specifically as follows:

[0049] Refer to the attached Figure 4 and attached Figure 5 As shown, the slide 4 includes:

[0050] The seat body 41 has a central hole 412 extending therethrough in the middle thereof, and a threaded hole 411 is provided at the top of the seat body 41;

[0051] There are a plurality of balls 42 installed in the center hole 412 so that the balls 42 form a rolling channel in the center hole 412 that contacts the guide rod 3.

[0052] In addition, in the above scheme, considering the convenience of disassembly and assembly of the single slide 4, for this purpose, refer to the attached Figure 6 As shown, the seat body 41 is composed of an independent docking seat 1 413 and a docking seat 2 414, wherein the sides of the docking seat 1 413 and the docking seat 2 414 are provided with side threaded holes 415 for receiving bolts, so that the docking seat 1 413 and the docking seat 2 414 are connected by bolts; in this solution, by designing the slide 4 as a split type, which is composed of two independent parts, when the slide 4 needs to be disassembled and assembled, it is only necessary to operate the slide 4 alone to complete the disassembly and assembly of the slide 4 itself, thereby improving the convenience of disassembly and assembly.

[0053] In the above embodiment, considering the operation accuracy of the telescopic cylinder 2, Figure 7 As shown, a sensor 7 is installed on a fixed plate 1 opposite to the telescopic cylinder 2 to detect the running distance of the connecting seat 6, and the sensor 7 is electrically connected to the telescopic cylinder 2. Among them, the sensor 7 is a position sensor or a pressure sensor;

[0054] When a position sensor is used, such as a grating scale, a magnetic scale or a travel switch, to directly measure the position of the telescopic cylinder 2, the telescopic cylinder 2 stops operating when the connecting base 6 reaches the set position, thereby providing high-resolution position feedback;

[0055] When a pressure sensor is used, the pressure condition of the telescopic cylinder 2 is monitored. When the set pressure value is reached, the telescopic cylinder 2 stops operating, ensuring that the system operates in a safe and stable state.

[0056] In the above embodiment, considering the operation effect of the telescopic cylinder 2, in order to avoid the collision or damage caused by excessive inertia during the operation of the telescopic cylinder 2, Figure 8 As shown, a set of buffer components 8 are installed on each of the two guide rods 3, and the two sets of buffer components 8 are arranged on a fixed plate 1 opposite to the telescopic cylinder 2;

[0057] In the above solution, the structure of the buffer component 8 is specifically as follows:

[0058] Refer to the attached Figure 8 As shown, the buffer assembly 8 includes:

[0059] An inner hole seat 81 is sleeved on the outside of the guide rod 3 and is bolted to a fixed plate 1 opposite to the telescopic cylinder 2;

[0060] The second inner hole seat 82 is sleeved on the outside of the guide rod 3 and is made of rubber material to improve the use effect;

[0061] The spring 83 is connected between the inner hole seat 1 81 and the inner hole seat 2 82 and is sleeved on the outside of the guide rod 3 so that when the inner hole seat 2 82 receives an impact, the spring 83 can play a buffering role.

[0062] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
