Description

Technical Field

[0001] This invention relates to the field of ring-cutting devices, and more specifically to a ring-cutting device for ampoules. Background Technology

[0002] An ampoule is a small, sealed container, usually made of glass, primarily used to hold and preserve liquids that require a highly pure and sterile environment, especially pharmaceuticals, vaccines, and cosmetic serums.

[0003] When using ampoules, to facilitate breaking them and drawing out the medication, a pre-cut groove, called a scoring ring, is usually made around the neck of the ampoule. This guides the ampoule to break along a predetermined line when force is applied, ensuring a clean break. This not only significantly reduces the risk of cuts to healthcare workers during operation but also reduces the probability of glass particles entering the medication.

[0004] Current ampoule ring-cutting devices still have the following problems when in use: 1. Due to the small size of ampoules and the close proximity of adjacent ampoules, when using a cutting device to make a circumferential cut on an ampoule, it is easy to scratch nearby ampoules, affecting the surrounding ampoules. At the same time, when the cutting device is pressed on a fixed-position ampoule, the support points at both ends of the ampoule are far from the cutting point, and the cutting pressure can easily cause the ampoule to break, resulting in increased production costs.

[0005] 2. Some cutting devices are fixedly connected to the lifting device. The cutting depth is controlled by the up and down movement of the lifting device. Since ampoules are made of glass, the thickness and shape of the formed bottle are uncontrollable. Cutting with a fixed pressing depth cannot adapt well to the shape of the bottle, affecting the cutting effect.

[0006] 3. When using sensors to detect the position of the cutting device and the bottle rotation device, dust will be generated during the ring cutting of ampoules. The falling dust will fall on the sensors below and cause malfunctions of the equipment.

[0007] Therefore, it is necessary to propose a ring-cutting device for ampoules to solve the above problems. Summary of the Invention

[0008] In view of the above situation and to overcome the defects of the prior art, the present invention provides a ring-cutting device for ampoules to solve the problems mentioned in the background art.

[0009] The technical solution is as follows: The present invention includes a conveying device body, a support frame connected to the conveying device body, symmetrically arranged chains connected to the support frame, an external drive device connected to the chains, and equally spaced support plates connected to opposite sides of the two chains.

[0010] Furthermore, a guide column located below the support frame is connected to the side wall of the conveying device body. An inner rod is slidably connected inside the guide column. An axial drive structure is connected to the outside of the inner rod. A rotating sleeve is rotatably connected to the side of the rotating seat away from the motor frame. A driven rod is connected to the outer wall of the rotating sleeve. An active rod is connected to the driven rod. An adjusting bolt that cooperates with the bending frame is connected to the top of one end of the active rod.

[0011] Furthermore, a first fixed block is connected to the end of the inner rod near the driven rod, and a movable block is sleeved on the inner rod. An adjusting bolt is rotatably connected to the first fixed block, and the adjusting bolt is threadedly connected to the movable block. A contact plate is connected to one side of the movable block, and the end of the driven rod near the contact plate is connected to the contact plate by a spring. The contact plate is provided with a beveled surface, and a bearing that contacts the beveled surface is rotatably connected to the end of the driven rod away from the rotating sleeve.

[0012] Furthermore, a drive motor is connected inside the conveying device body, and the output end of the drive motor is connected to a first rotating shaft. A first cam disk is rotatably connected to the first rotating shaft. A first support plate is connected inside the conveying device body, and a first swing frame is rotatably connected to one side of the first support plate. A sliding groove is provided on the top of the first swing frame. The end of the inner rod away from the first fixed block is connected to a pin located in the sliding groove. The end of the first swing frame away from the pin contacts the first cam disk. The first swing frame and the first support plate are connected by a torsion spring.

[0013] Furthermore, a second fixing block is connected to the end of the inner rod away from the first fixing block, a guide frame is connected inside the conveying device body, a guide groove is provided in the guide frame, and a bearing located in the guide groove is rotatably connected to one end of the second fixing block.

[0014] Furthermore, a second rotating shaft located below the lifting column is rotatably connected within the body of the conveying device. The second rotating shaft is externally connected to a rotating drive structure. One end of the second rotating shaft is connected to a lifting frame. The bottom of the lifting column is in contact with the lifting frame. A second support plate is connected to one side of the body of the conveying device. The lifting column is slidably connected within the second support plate. The lifting column and the second support plate are connected by a spring.

[0015] Furthermore, a first connecting rod is connected to the end of the second rotating shaft away from the lifting frame. A third rotating shaft and a second swing frame are rotatably connected within the body of the conveying device. A second connecting rod is rotatably connected between the bottom of the second swing frame and the first connecting rod. A second cam disk is connected to the third rotating shaft. The top of the second swing frame is in contact with the second cam disk. The third rotating shaft and the first rotating shaft are connected by a bevel gear transmission structure.

[0016] Furthermore, the conveying device body is connected to an air blowing pipe, the air blowing pipe is externally connected to an air supply device, the air blowing end of the air blowing pipe is located obliquely above the cutting point, and a negative pressure gas collection hood located below the clamping roller is connected inside the support frame, and a negative pressure device is externally connected to the negative pressure gas collection hood.

[0017] Compared with existing known technologies, the technical solution provided by this invention has the following significant advantages: 1. Through the coordinated setup of the cutting motor, cutting blade, and clamping rollers, the clamping rollers drive the ampoule to rotate, thereby performing a uniform ring-cutting action. When the ring-cutting device rotates downwards, it performs ring-cutting on the neck of the ampoule under the action of gravity, which has the function of maintaining a consistent cutting depth. Even if the shape of the bottle is different, the ring-cutting state is guaranteed to be consistent, thus improving the efficiency of ring-cutting.

[0018] 2. This device is equipped with a roller frame and support roller at the bottom of the clamping roller, which can lift the ampoule to be ring-cut, so that it comes into contact with the clamping roller at the top. This can prevent the cutting blade from contacting other ampoules during ring cutting, improve the consistency of ampoule ring cutting, and at the same time improve the support capacity of the ampoule, avoid the side supports from breaking easily, and reduce the generation of waste.

[0019] 3. The combination of the first fixed block, the moving block, and the adjusting bolt facilitates the adjustment of the rotation angle of the cutting motor, thereby controlling the depth of the ring cut. This makes it convenient for ring cutting different types of ampoules. At the same time, the adjusting bolt on the drive rod can also adjust the lifting angle and the ring cut depth, providing multiple adjustment methods for easy use.

[0020] 4. Through the transmission connection of the first cam plate, the second cam plate and the drive motor, the inner rod and the second rotating shaft can be kept in sync, thus cooperating and avoiding the use of sensors and other structures, which improves the stability of operation. At the same time, the air blowing pipe and negative pressure air collection hood on the conveying device body can collect the generated dust particles, reducing the impact on the environment.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] The conventional components and key load-bearing components in this case are selected in accordance with standards in terms of material selection, heat treatment process and structural dimensions to ensure that they have sufficient strength, stiffness and fatigue resistance under rated load and expected working conditions. These are all conventional design considerations well known to those skilled in the art.

[0025] Depend on Figures 1 to 7 Provided is a conveyor body 101, which is placed on an ampoule production line. Upstream is an ampoule forming machine, and ampoules leaving the forming machine are transported via a chain 103. The production line uses the chain 103 to convey the vials, and a support plate 104 is connected to the chain 103. The shape of the support plate 104 is referenced. Figure 2The conveying device body 101 is connected to a support frame 102, which supports the chain 103. Symmetrically arranged chains 103 are driven onto the support frame 102. Each chain 103 is externally connected to a drive device. The two chains 103 are connected via a connecting structure to maintain synchronous movement. This is an existing device and will not be described in detail here. Equally spaced support plates 104 are connected to opposite sides of the two chains 103. The top of each support plate 104 has a groove, and the two ends of the ampoule are placed within these grooves. Because the two ends of the ampoule have different diameters, in one embodiment, the support plates 104 on the two chains 103 have different heights. The angle of the support plate 104 near the ampoule opening is higher than the other support plate 104, ensuring the ampoule remains horizontal when supported. The side wall of the conveying device body 101 is slidably connected to a lifting column 105 located below the support frame 102. The lifting column 105 is vertically arranged and reciprocates in the vertical direction. The lifting column 105 is externally connected to a lifting drive structure. The top of the lifting column 105 is connected to a roller frame 106. The top of the roller frame 106 is rotatably connected to a support wheel 107. The support wheel 107 and the clamping roller 110 are fitted with high-temperature resistant anti-slip rubber rings. The conveying device body 101 is connected to an upper support 108 located above the support frame 102. A pressure roller motor 109 is connected to one side of the upper support 108. The output end of the pressure roller motor 109 is connected to a clamping roller 110. The plane of the clamping roller 110 is perpendicular to the axis of the ampoule. The clamping roller 110 is configured to cooperate with the support wheel 107. The pressure roller motor 109 is always rotating. When the ampoule comes into contact with the clamping roller 110, it will be driven to rotate by the pressure roller motor 109. The support frame 102 is connected to a horizontal bracket 149 at one end away from the conveying device body 101. The horizontal bracket 149 provides support, and a rotating seat 111 is connected to the horizontal bracket 149. A motor frame 112 is rotatably connected to one side of the rotating seat 111. The motor frame 112 can be opened to adjust the position of the internal cutting motor 113, thereby adapting to the cutting of ampoules of different lengths. The cutting motor 113 is connected inside the motor frame 112, and a cutting blade 114 is connected to the output end of the cutting motor 113. The cutting blade 114 is located above the neck of the ampoule. A bending frame 115 is connected to the bottom of the motor frame 112. The bending frame 115 is L-shaped and has a lifting structure that moves up and down. When the ampoule moves upward and contacts the clamping roller 110, the cutting motor 113 rotates along the rotating seat 111, so that the cutting blade 114 at the output end corresponds to the neck of the ampoule, thereby performing a circumferential cutting action.

[0026] Since each ampoule model has a different required ring-cut depth, the following provides a structure for easily adjusting the ring-cut depth: (Reference) Figure 3 and Figure 4 The conveying device body 101 has a guide column 116 connected to its side wall, located below the support frame 102. The guide column 116 is parallel to the axis of the cutting motor 113. An inner rod 117 is slidably connected inside the guide column 116. The inner rod 117 is externally connected to an axial drive structure, and the inner rod 117 reciprocates axially within the guide column 116. A rotating sleeve 118 is rotatably connected to the side of the rotating seat 111 away from the motor frame 112. The rotation axis of the rotating sleeve 118 is connected to the motor frame. The rotation axes of 112 are located on the same axis. A driven rod 119 is connected to the outer wall of the rotating sleeve 118, and a driving rod 120 is connected to the driven rod 119. When the driven rod 119 rotates along the rotation axis, it will drive the driving rod 120 to rotate together. One end of the driving rod 120 is connected to an adjusting bolt 121 that cooperates with the bending frame 115. The height of the adjusting bolt 121 can be adjusted, which can adjust the cutting depth and lifting height of the cutting blade 114. When the upward lifting angle is small, the contact time with the bottle will be prolonged. With the rotation time remaining unchanged, the cutting depth can be increased.

[0027] Since the connection position between the inner rod 117 and the driven rod 119 changes when they move, the following structure is provided to adapt to the connection position: Reference Figure 2 and Figure 4 The inner rod 117 is connected to a first fixing block 122 near the driven rod 119. The first fixing block 122 is fixedly connected to the inner rod 117. A moving block 123 is sleeved on the inner rod 117. The moving block 123 is slidably connected to the inner rod 117 and is located at the end near the conveying device body 101. An adjusting bolt 124 is rotatably connected to the first fixing block 122. The adjusting bolt 124 is threadedly connected to the moving block 123. When the adjusting bolt 124 is rotated, the positional relationship of the moving block 123 on the inner rod 117 can be adjusted. One side of the moving block 123 is connected to a contact plate 125. The end of the driven rod 119 near the contact plate 125 is connected to the contact plate 125 by a spring 126. The spring 126 is in a stretched state. The contact plate 125 is provided with an inclined surface 127. The end of the driven rod 119 away from the rotating sleeve 118 is rotatably connected to a bearing 128 that contacts the inclined surface 127. The spring 126 pulls the bearing 128 on the driven rod 119 to contact the inclined surface 127. When the inner rod 117 drives the driven rod 119 to move, the bearing 128 will slide on the inclined surface 127 to adapt to the positional change between the inner rod 117 and the driven rod 119.

[0028] When the driven rod 119 rotates along the rotating sleeve 118 toward the end away from the conveying device body 101, it drives the bending frame 115 to rotate downwards via the driving rod 120. Under the action of gravity, the bending frame 115 drives the cutting motor 113 to rotate, and the cutting blade 114 is used to perform a ring cut on the neck of the ampoule. In one embodiment, the driving rod 120 rotates downwards at a relatively fast speed, so that the cutting blade 114 performs a ring cut on the ampoule under the action of gravity. Since the ampoule is in a rotating state, the ring cut depth can be kept consistent.

[0029] In some production processes, after the ampoules are ring-cut, the necks need to be wire-cut to improve the efficiency and smoothness of breaking them. A color-coded mark is used above the neck for easy user identification. Therefore, multiple cutting devices are installed on the conveyor body 101. The wire-cutting device is the same as the ring-cutting device, except that the pressure roller motor 109 at the top does not rotate, thus achieving the wire-cutting effect. The marking structure is an existing device and will not be described in detail here. To improve ease of breaking, the thickness of the cutting blade 114 is changed.

[0030] To drive the inner rod 117 to reciprocate, and simultaneously to drive the inner rod 117 on the wire cutting device to move, a driving structure is provided below: (Refer to...) Figure 2 and Figure 4The conveying device body 101 is internally connected to a drive motor 129. The output end of the drive motor 129 is connected to a first rotating shaft 130. A coupling connects the drive motor 129 and the first rotating shaft 130. A first cam disk 131 is rotatably connected to the first rotating shaft 130. The drive motor 129 drives the first cam disk 131 to rotate in one direction. The conveying device body 101 is internally connected to a first support plate 132. A first swing frame 133 is rotatably connected to one side of the first support plate 132. A torsion spring connects the first swing frame 133 and the first support plate 132, so that the end of the first swing frame 133 facing the first cam disk 131 is always pressed against the first cam disk 131. Because the connection point between the first swing frame 133 and the inner rod 117 changes when the first swing frame 133 rotates, a sliding groove 134 is provided on the top of the first swing frame 133. The end of the inner rod 117 away from the first fixed block 122 is connected to a pin located in the sliding groove 134. The sliding of the inner rod 117 in the sliding groove 134 adapts to the change in the connection position between the two. The end of the first swing frame 133 away from the pin is in contact with the first cam disk 131. The first swing frame 133 and the first support plate 132 are connected by a torsion spring. The drive motor 129 is always rotating. The frequency at which the first cam disk 131 lifts the first swing frame 133 is the same as the moving speed of the chain 103. The chain 103 moves a certain distance and then stops. At this time, the ampoule at the corresponding position is lifted and cut in a ring. After the ring cut, it falls back onto the support plate 104 on the chain 103. Then the chain 103 continues to move, and so on.

[0031] The reciprocating movement of the inner rod 117 within the guide post 116 can lead to unstable movement, such as rotation. The following structure improves this stability: [Reference] Figure 5 and Figure 6 The inner rod 117 is connected to a second fixing block 135 at one end away from the first fixing block 122. A guide frame 136 is connected inside the conveying device body 101. The guide frame 136 is arranged parallel to the axis of the inner rod 117. A guide groove 137 is opened in the guide frame 136. One end of the second fixing block 135 is rotatably connected to a bearing 128 located in the guide groove 137. When the inner rod 117 moves, the sliding of the second fixing block 135 on the outer wall in the guide frame 136 plays a role in stabilizing the movement. The bearing 128 reduces the friction when moving in the guide groove 137.

[0032] The lifting column 105 needs to move back and forth up and down. The following is a structure for propelling this back and forth movement: (Reference) Figure 2 and Figure 3The conveying device body 101 is rotatably connected to a second rotating shaft 138 located below the lifting column 105. The second rotating shaft 138 is externally connected to a rotating drive structure, which performs reciprocating rotational motion, thereby driving the second rotating shaft 138 to reciprocate. One end of the second rotating shaft 138 is connected to a lifting frame 139, and the bottom of the lifting column 105 contacts the lifting frame 139. When the second rotating shaft 138 drives the lifting frame 139 to rotate, it will lift the top lifting column 105 upwards. A second support plate 140 is connected to one side of the conveying device body 101, and the lifting column 105 is slidably connected within the second support plate 140. The lifting column 105 and the second support plate 140 are connected by a spring 126, which is in a stretched state to keep the lifting column 105 at the bottom.

[0033] The lifting speed of the lifting column 105 must be the same as the moving frequency of the inner rod 117. The following is a structure that maintains the same operating frequency for both: [Reference] Figure 5 and Figure 6 The second rotating shaft 138, at the end furthest from the lifting frame 139, is connected to a first connecting rod 141. A third rotating shaft 142 and a second swing frame 143 are rotatably connected within the conveying device body 101. Both the first and second swing frames 133 are L-shaped, and rollers are rotatably connected to the ends that contact the cam disc. The rollers reduce friction between the swing frame 143 and the cam disc. A second connecting rod 144 is rotatably connected between the bottom of the second swing frame 143 and the first connecting rod 141. When the second swing frame 143 rotates, the second rotating shaft 138 is driven to rotate through the connection between the second connecting rod 144 and the first connecting rod 141. A second cam disc 145 is connected to the third rotating shaft 142, and the top of the second swing frame 143 contacts the second cam disc 145. The third rotating shaft 142 and the first rotating shaft 130 are connected via a bevel gear transmission structure 146, which consists of multiple bevel gears. (Structure reference...) Figure 6 , Figure 6 The black line with an arrow indicates the direction of rotation.

[0034] Since glass dust is generated when cutting ampoules, the following structure is provided for collecting glass dust to reduce the impact on the surrounding environment: [Reference] Figure 1 and Figure 5The conveying device body 101 is connected to an air blowing pipe 147, which is externally connected to an air supply device. In one embodiment, the cutting blade 114 rotates towards the air blowing pipe 147, and the ejected airflow is used to blow the dust downwards to prevent the dust from scattering. The blowing end of the air blowing pipe 147 is located diagonally above the cutting point. A negative pressure gas collection hood 148 is connected inside the support frame 102 and located below the clamping roller 110. The negative pressure gas collection hood 148 is externally connected to a negative pressure device. The downward-moving dust will be affected by the negative pressure of the negative pressure gas collection hood 148, and the dust will be collected by the negative pressure.

[0035] In use, the conveying device body 101 is placed at the unloading point of the ampoule forming machine. The chain 103 on the conveying device body 101 is used to convey the ampoules. The chain 103 moves intermittently. When the ampoule moves below the clamping roller 110, the lifting column 105 moves upward, lifting the ampoule through the top roller frame 106. The roller frame 106 has four support wheels 107, which are used to clamp the cylindrical body of the ampoule. When moving upward, they will contact the bottom clamping roller 110, causing the clamping roller 110 to rotate the ampoule. At the same time, the cutting motor 113 will also press down, and the cutting blade 114 at the output end will perform a ring cut on the neck of the ampoule. After the ring cut, the lifting column 105 will return to its original position, and the output end of the cutting motor 113 will lift up. This ring cut is repeated in sequence.

[0036] The dust cut off is collected in the negative pressure dust collection hood 148 by the airflow blown out by the air blowing pipe 147.

[0037] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
