[0048] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0049] like Figure 1 As shown, an ampoule bottle sliding mechanism comprises a stroke assembly 1 and a guide plate 3, a slide drive assembly 2 mounted at the free end of the guide plate 3, the fixed end of the guide plate 3 being mounted on the stroke assembly 1, and the free end of the slide drive assembly 2 being connected with a slide portion 4. The stroke assembly 1 pushes the slide drive assembly 2 from the standby position to the working position, the blade 41 of the slide portion 4 protrudes outside the edge of the guide plate 3 and abuts against the narrow waist bottleneck of the ampoule bottle, and the slide drive assembly 2 drives the blade 41 of the slide portion 4 and the narrow waist bottleneck of the ampoule bottle to slide relative to each other for multiple times according to a preset trajectory, so as to process a pre-folding mark.

[0050] The blade 41 and the narrow waist neck of the ampoule bottle slide and rub to produce scratches, which may occur in the following situations:

[0051] The ampoule bottle may be fixed, and the blade 41 may rotate along the ampoule bottle, and slide and carve along the same circular scratch multiple times to produce a pre-folding scratch; or the blade 41 may be fixed, and the ampoule bottle may be driven to rotate, and the blade 41 may slide and carve along the same circular scratch multiple times at the bottleneck of the ampoule bottle to produce a pre-folding scratch; or, the ampoule bottle may be fixed, and the blade 41 may be limited to one side of the ampoule bottle and move in a straight line perpendicular to the bottleneck to slide and carve out the scratch.

[0052] In the utility model, the ampoule bottle and the blade 41 move relative to each other to carve the pre-folding mark. The ampoule bottle is fixed on the working position, and the blade 41 is limited to one side of the ampoule bottle and moves linearly vertically to the bottleneck to slide and carve the mark.

[0053] The stroke component 1 includes a guide rail sliding module, which is driven by a motor or a cylinder. The stroke component 1 moves, driving the guide plate 3, the slide driving component 2, and the slide part 4 to move along the guide rail sliding module as a whole, from the standby position to the working position, and stays at the working position for a period of time. During the interval of stay time, the slide driving component 2 drives the blade 41 of the slide part 4 and the narrow waist bottleneck of the ampoule bottle to slide relative to each other for multiple times according to a preset trajectory, thereby processing a pre-folding scratch.

[0054] The slide part 4 includes a blade 41, which is fixedly mounted on a blade seat 42, and the blade seat 42 is directly or indirectly mounted on the second guide rail sliding module 21 through a connecting part 5. When the slide part 4 moves with the guide plate 3, the blade seat 42 and the blade 41 can be fixed and not move with the guide plate 3, or can move synchronously with the guide plate 3. Among them, the blade seat 42 and the blade 41 do not move synchronously with the guide plate 3, and a hole or a groove or a retractable structure is set on the guide plate 3 to adapt to the reciprocating movement of the guide plate 3.

[0055] For example, the present invention adopts one of the embodiments, that is, the blade 41 is fixed in the working position and keeps contact with the narrow waist bottleneck of the ampoule bottle in the working state, and the blade seat 42 is installed on the second guide rail sliding module 21 through the connecting part 5.

[0056] For details, refer to the attached Figure 2 The connecting part 5 includes a support 53 and a linear shaft 51 coaxially sleeved with a spring 52. The linear shaft 51 is mounted on the support 53 and its end extends outside the support 53. The support 53 is fixedly mounted on the second guide rail sliding module 21. The spring 52 is distributed on the blade seat 42 and the rod body of the linear shaft 51 of the support 53; the guide plate 3 moves, driving the linear shaft 51 to move relative to the support 53, and the spring 52 stretches or contracts to adapt to the position movement of the support 53.

[0057] Specifically, the travel assembly 1 includes a first guide rail sliding module 11 and a first power unit 12. The first guide rail sliding module 11 is fixedly mounted on the base 6, and one end of the guide plate 3 is mounted on the slider of the first guide rail sliding module 11. The first power unit 12 serves as a power source, and drives the guide plate 3 to move back and forth along the first guide rail sliding module 11 in a straight line through the first transmission unit 13, thereby driving the guide plate 3 to drive the slide portion 4 at the end and the slide drive assembly 2 to move between the standby position and the working position.

[0058] The slide drive assembly 2 is mounted at the other end of the guide plate 3 and moves with the guide plate 3. The slide drive assembly 2 includes a second guide rail sliding module 21 and a second power unit 22. The second guide rail sliding module 21 is fixedly mounted on the guide plate 3. Under the action of the second transmission unit 23, the second power unit 22 drives the blade 41 to abut against the narrow waist bottleneck of the ampoule bottle and move back and forth linearly to carve out a pre-folding mark.

[0059] The first power unit 12 and the second power unit 22 are respectively motors or cylinders. In one embodiment, based on the common installation of guide rail sliding modules and the installation layout of motors or cylinders, the output shaft of the first power unit 12 directly drives the corresponding first guide rail sliding module 11 or second guide rail sliding module 21 (the motor or cylinder is arranged outside the guide plate 3 along the direction of the slide rail). In this way, after the motor or cylinder is installed, it protrudes outside the guide plate 3 area, which is suitable for the situation where there is sufficient space.

[0060] The first power unit 12 and the second power unit 22 respectively use motors or cylinders. In another embodiment, the first power unit 12 is fixedly arranged below the guide plate 3, the output end of the first power unit 12 faces upward, and drives the guide plate 3 to move through the first transmission unit 13.

[0061] For details, refer to the attached Figure 3The first transmission part 13 includes a first transmission shaft 131 and a first limiting rod 133. The bottom end of the first transmission shaft 131 is fixedly connected to the output end of the first power part 12. A first stroke plate 134 with a first stroke hole 135 is arranged above the top end of the first transmission shaft 131, and a first round cap 132 is coaxially covered on the top end of the first transmission shaft 131; the first limiting rod 133 is vertically fixed on the top surface of the first round cap 132 near the circumferential edge, inserted into the first stroke hole 135 and limitedly fitted in the first stroke hole 135.

[0062] The first travel plate 134 is fixedly connected to the guide plate 3 at the bottom via a connecting column 136 , and a first waist hole 31 for accommodating the first transmission shaft 131 is formed on the guide plate 3 .

[0063] The first limit rod 133 is limited by the first stroke hole 135 and cooperates with the first stroke hole 135 to drive the guide plate 3 to move. Figure 6 As shown, the first stroke plate 134 is fixedly connected to the guide plate 3 and moves synchronously. The first round cap 132 makes a circular motion driven by the first transmission shaft 131, and the first limit rod 133 is eccentrically installed on the first round cap 132. In the absence of the first stroke hole 135, the first limit rod 133 and the first round cap 132 make concentric circular motion. Due to the existence of the first stroke hole 135, the circular rotation motion of the first limit rod 133 is limited, and the first limit rod 133 always remains in the first stroke hole 135, but the first limit rod 133 always has a tendency to rotate in a circle, so stress is generated on the side wall of the first stroke hole 135, thereby pushing the first stroke plate 134 to move. The first stroke plate 134 is fixedly connected to the guide plate 3. Therefore, the first stroke plate 134 and the guide plate 3 move linearly along the second guide rail sliding module 21 as a whole.

[0064] The first stroke hole 135 is in the shape of a cashew nut as a whole, and a concave portion of the first stroke hole 135 faces the standby position.

[0065] As attached Figure 6As shown, from top to bottom, initially, the first limit rod 133 is located in the middle of the first stroke hole 135. When subjected to stress, the first stroke plate 134 moves to one side of the working position, and the first limit rod 133 moves in the first stroke hole 135 toward the bottom end of the first stroke hole 135, and then moves back to the middle position. Since the curvature of the inner and outer wall curves near the middle position of the first stroke hole 135 is close to the inner and outer circumferential arcs of the first limit rod 133, the mutual stress between the first limit rod 133 and the first stroke hole 135 is very small, which is not enough to move the first stroke plate 134 and the guide plate 3. Therefore, after the guide plate 3 sends the slide part 4 and the slide drive assembly 2 to the working position, it will stay for a period of time. During the interval, the blade 41 is affected by the slide drive assembly 2 and moves in a straight line to slide and scratch the narrow waist bottleneck of the ampoule bottle.

[0066] When the first limiting rod 133 returns to the middle position from the other end, the stress between the first limiting rod 133 and the first travel hole 135 pushes the guide plate 3 and the slide drive assembly 2 back to the standby position to wait for the next working process.

[0067] Refer to the attached Figure 4 The second power unit 22 is fixedly arranged below the guide plate 3; the second transmission unit 23 includes a second transmission shaft 231 and a second limit rod 233, and the bottom end of the second transmission shaft 231 is fixedly connected to the output end of the second power unit 22.

[0068] A second stroke plate 234 with a second stroke hole 235 is arranged above the top end of the second transmission shaft 231, and a second round cap 232 is coaxially covered on the top end of the second transmission shaft 231; the second limiting rod 233 is vertically fixed on the top surface of the second round cap 232 near the circumferential edge, inserted into the second stroke hole 235 and limitedly fitted in the second stroke hole 235.

[0069] The second travel plate 234 is fixedly connected to the slider of the second guide rail sliding module 21 ; a mounting hole 32 for accommodating the second round cap 232 is provided on the guide plate 3 .

[0070] The second limiting rod 233 is limited by the second stroke hole 235 and cooperates with the second stroke hole 235 to drive the guide plate 3 to move. Figure 5 As shown, starting from the first view state on the upper left, the blade 41 moves back and forth along the length direction of the slide rail. The specific process is:

[0071] The second power unit 22 drives the second round cap 232 and the second limiting rod 233 to move in a circle through the second transmission shaft 231. The rotation trajectory of the second limiting rod 233 is limited by the second stroke hole 235. Stress is generated between the second limiting rod 233 and the side wall of the second stroke hole 235. Under the action of the stress, the second stroke plate 234, the slide portion 4 and the connecting portion 5 are pushed to move back and forth in a straight line along the second guide rail sliding module 21 as a whole, so as to slide and carve scratches at the narrow waist bottleneck of the ampoule bottle; the second stroke hole 235 adopts a waist-shaped hole, and the second limiting rod 233 itself moves along the second stroke hole 235. The length direction of the second stroke hole 235 is consistent with the pushing direction of the guide plate 3.

[0072] In addition, a sensing component 7 is installed on the base 6, including a sensing sheet 71 and a proximity switch 72. The proximity switch 72 is fixed on the base 6, and the sensing sheet 71 is fixedly installed on the guide plate 3 and protrudes outside the guide plate 3; the sensing sheet 71 is opposite to the proximity switch 72 and is in a standby position. After the next ampoule bottle is in place, the first power unit 12 and the second power unit 22 are in operation, and the guide plate 3 drives the sensing sheet 71 away from the proximity switch 72 and starts to move and scratch. After the scratching is completed, the guide plate 3 drives the sensing sheet 71 to approach and return to above the proximity switch 72, waiting for the next round of scratching operation.

[0073] In summary, the utility model arranges the stroke assembly 1, the slide drive assembly 2 and the guide plate 3, and arranges the power parts of the stroke assembly 1 and the slide drive assembly 2 at the bottom of the guide plate 3, thereby saving space, reducing the overall size of the equipment and making the structure more compact.

[0074] The first power unit 12 of the stroke assembly 1 drives the guide plate 3 carrying the slide drive assembly 2 to the working position through the first transmission unit 13, and the first limit rod 133 of the first transmission unit 13 cooperates with the first stroke hole 135 on the first stroke plate 134, so that the first transmission unit 13 does not simply drive the guide plate 3 to move back and forth, but stays at the far end, i.e., the working position, for a period of time; during this interval, the second power unit 22 of the slide drive assembly 2 drives the blade 41 to slide on the ampoule bottle through the second transmission unit 23 to scratch the ampoule bottle, mechanically carve out the scratch, open the bottle head along the scratch, reduce the generation of glass fragments when opening the bottle cap, and improve the safety of the bottle opening operation.

[0075] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
