[0001] This utility model relates to the field of lid opening device technology, and in particular to a sealing lid opening device. Background Technology

[0002] With the rapid development of the dairy industry, cream has become an important food ingredient and is widely used. To ensure the quality and safety of cream during transportation and storage, existing technologies typically use specialized packaging bags for sealing. To prevent leakage during transportation, these bags have a sealing structure protruding from the outer circumference of the cap. This sealing structure fits tightly with the bag's seal, making it difficult for personnel to remove the cap, thus affecting work efficiency. Prying open the cap with tools can easily damage the cap and seal, making it difficult to remove the cream. Utility Model Content

[0003] The purpose of this invention is to provide a sealing cap opening device that does not require external pulling force from personnel, saving time and effort, improving work efficiency, and, compared to forcibly prying open the sealing cap, will not damage the sealing cap and the sealing nozzle, making it easier to remove materials.

[0004] To achieve the above objectives, this utility model provides the following technical solution: In a first aspect, this utility model provides a sealing cover opening device, including a limiting component, a driving mechanism, and an outward pulling component; The limiting component has a first limiting channel, which is used for the nozzle to enter and exit and to limit the position of the nozzle along the axial direction of the nozzle; The driving mechanism is fixedly disposed relative to the limiting component, the outward pulling component is connected to the driving mechanism, and the outward pulling component has a second limiting channel that is spaced apart from and parallel to the first limiting channel.

[0010] In an optional embodiment, a first discharge gap is provided between the outer shell and the bottom end of the external pull-out component, and a second discharge gap is provided between the outer shell and the bottom end of the limiting component. The second discharge gap communicates with the first discharge gap to discharge the pulled-out sealing cap.

[0011] In an optional embodiment, the sealing cap opening device further includes a recycling box located outside the housing, the recycling box being used to receive the sealing cap that falls off the housing.

[0012] In an optional embodiment, the side opening is connected to a baffle, the baffle is disposed opposite to the end of the first limiting channel for entering and exiting the sealing nozzle, and there is a first gap between the baffle and the first limiting channel.

Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] The first aspect of this utility model provides a sealing cover opening device, such as... Figure 1 and Figure 2 As shown, it includes a limiting component 1, a driving mechanism 2, and an external pulling component 3; The limiting component 1 has a first limiting channel 11, which is used for the sealing nozzle 4 to enter and exit and to limit the position of the sealing nozzle 4 along the axial direction of the sealing nozzle 4; The drive mechanism 2 is fixedly set relative to the limiting component 1. The pull-out component 3 is connected to the drive mechanism 2. The pull-out component 3 has a second limiting channel 31 that is spaced apart from and parallel to the first limiting channel 11. The second limiting channel 31 is used for the sealing cover 5 to enter and exit and to pull out the sealing cover 5 under the drive of the drive mechanism 2.

[0024] Reference Figure 3 and Figure 4 As shown, when the sealing cap opening device provided in the above embodiment is in use, the sealing nozzle 4 is slid into the first limiting channel 11, and at the same time, the sealing cap 5 connected to the sealing nozzle 4 is slid into the second limiting channel 31. The first limiting channel 11 can limit the position of the sealing nozzle 4 along the axial direction of the sealing nozzle 4. Since the driving mechanism 2 is fixedly set relative to the limiting component 1, after the driving mechanism 2 is activated, it can drive the external pulling component 3 to pull out the sealing cap 5, thereby realizing the disassembly of the sealing cap 5.

[0025] Compared with the prior art, the sealing cap opening device provided in the above embodiment does not require personnel to apply external pulling force, which saves time and effort, improves work efficiency, and will not damage the sealing cap and the sealing nozzle compared with forcibly prying open the sealing cap, making it easier to take out materials.

[0026] The structure of the limiting component 1 is described in detail below: In alternative implementations, such as Figure 1 and Figure 2 As shown, the limiting component 1 includes a first limiting plate 12 and a second limiting plate 13, and a first limiting channel 11 is formed between the first limiting plate 12 and the second limiting plate 13.

[0027] In the above embodiments, the first limiting channel 11 is formed by the first limiting plate 12 and the second limiting plate 13, which makes the structure of the limiting component 1 simpler and facilitates the processing of the sealing cover opening device.

[0028] The first limiting plate 12 and the second limiting plate 13 are preferably structural components with high rigidity and wear resistance, such as those made of metal or high-strength engineering plastics, to ensure stable positioning of the sealing nozzle 4 during frequent use. A certain distance is maintained between the opposing surfaces of the two limiting plates, thereby forming a first limiting channel 11. This distance is designed according to the standard outer diameter of the sealing nozzle 4, allowing the sealing nozzle 4 to smoothly slide into or out of the first limiting channel 11 along its own radial direction, while preventing excessive radial offset, thus achieving accurate positioning of the sealing nozzle 4.

[0029] Specifically, the outer circumferential surface of the sealing nozzle 4 is usually provided with multiple rings of protrusions, which are distributed at intervals along the axial direction of the sealing nozzle 4. The first limiting plate 12 and the second limiting plate 13 can extend into any two adjacent protrusions near the edge of the first limiting channel 11. Thus, when the outer pulling assembly 3 pulls out the sealing cover 5, the first limiting plate 12 and the second limiting plate 13 fix the sealing nozzle 4 along the axial direction of the sealing nozzle 4, and the pulling force of the outer pulling assembly 3 can be fully applied to the sealing cover 5.

[0030] In addition, both the first limiting plate 12 and the second limiting plate 13 can be bent into an "L" shape. One side of the plate can be fixed to other supporting objects by means of bolts or welding, while the other side forms the first limiting channel 11.

[0031] The first limiting channel 11 can extend horizontally, vertically, or at a certain angle to the vertical direction. In other words, the extension direction of the first limiting channel 11 is not limited to a fixed direction.

[0032] In alternative implementations, such as Figure 5As shown, the first limiting channel 11 extends vertically, and at least one end of the first limiting channel 11 is provided with a first opening 111 for the sealing nozzle 4 to enter and exit. That is, the first opening 111 is provided at the top and / or bottom of the first limiting channel 11 so that the sealing nozzle 4 can be inserted or removed from above or below.

[0033] In the above embodiment, the first limiting channel 11 extends vertically, which facilitates personnel to observe the docking status of the sealing nozzle 4 and the first limiting channel 11 from above during use.

[0034] In one implementation, such as Figure 5 As shown, the top of the first limiting channel 11 is provided with a first opening 111. The sealing nozzle 4 is inserted into the channel from top to bottom, and the sealing nozzle 4 is axially limited by the first limiting plate 12 and the second limiting plate 13, thereby ensuring that it remains stable during the subsequent disassembly of the sealing cover 5.

[0035] The size of the first opening 111 can be slightly larger than the outer diameter of the sealing nozzle 4 to ensure that the sealing nozzle 4 can be smoothly inserted, while preventing the gap from being too large and causing unstable positioning. In some embodiments, the first opening 111 may also be provided with a guide chamfer or guide slope to guide the sealing nozzle 4 smoothly into the first limiting channel 11, thereby improving the fault tolerance and convenience of operation.

[0036] The structure of the pull-out component 3 is described in detail below: In alternative implementations, such as Figure 6 As shown, the external pull-out component 3 includes a third limiting plate 32 and a fourth limiting plate 33, both of which are connected to the drive mechanism 2, and a second limiting channel 31 is formed between the third limiting plate 32 and the fourth limiting plate 33.

[0037] In the above embodiments, the second limiting channel 31 is formed by the third limiting plate 32 and the fourth limiting plate 33, which makes the structure of the external pull-out component 3 simpler and facilitates the processing of the sealing cover opening device.

[0038] The third limiting plate 32 and the fourth limiting plate 33 are preferably structural components with high rigidity and wear resistance, such as those made of metal or high-strength engineering plastics, to ensure stable limiting of the sealing cover 5 during frequent use.

[0039] A certain distance is maintained between the opposing surfaces of the third limiting plate 32 and the fourth limiting plate 33, thereby forming a second limiting channel 31. The second limiting channel 31 is opposite to and spaced apart from the first limiting channel 11 along the outward pulling direction of the sealing cover 5. The above-mentioned spacing is designed according to the standard outer diameter of the sealing cover 5, so that the sealing cover 5 can smoothly slide into or out of the second limiting channel 31 along its own radial direction, while preventing the sealing cover 5 from falling out of the second limiting channel 31 when it is pulled outward.

[0040] Specifically, the end of the sealing cap 5 furthest from the packaging bag usually has a radial protrusion. The distance between the protrusions can be smaller than the outer diameter of the protrusions. The third limiting plate 32 and the fourth limiting plate 33 can be removed by pulling out the protrusions.

[0041] In addition, such as Figure 6 As shown, both the third limiting plate 32 and the fourth limiting plate 33 can be bent into an "L" shape. One side of the plate can be connected to the drive mechanism 2 by bolts or other connecting parts, and the other side forms the second limiting channel 31.

[0042] Of course, the shapes of the third limiting plate 32 and the fourth limiting plate 33 are not limited to the one mentioned above; they can also be "Z" shaped or "T" shaped, etc.

[0043] Similar to the first limiting channel 11, the second limiting channel 31 can extend horizontally, vertically, or at a certain angle to the vertical direction. In other words, the extension direction of the second limiting channel 31 is not limited to a fixed direction.

[0044] In an optional embodiment, the second limiting channel 31 extends in a vertical direction, and at least one end of the second limiting channel 31 is provided with a second opening 311 for the sealing cover 5 to enter and exit.

[0045] In one implementation, such as Figure 5 As shown, the top of the second limiting channel 31 is provided with a second opening 311, which makes it convenient for personnel to observe the docking status of the sealing cover 5 and the second limiting channel 31 from above during use. The sealing cover 5 can be inserted into the channel from top to bottom.

[0046] The structure of drive mechanism 2 is described in detail below: The drive mechanism 2 may include a pneumatic cylinder, a hydraulic cylinder, or a linear motor, which can drive the sealing cover 5 to perform linear reciprocating motion.

[0047] The fixed end of the drive mechanism 2 can be installed on the limit component 1, thereby ensuring that the drive mechanism 2 is fixed relative to the limit component 1.

[0048] like Figure 6 As shown, when the external pull-out assembly 3 includes a third limiting plate 32 and a fourth limiting plate 33, the drive mechanism 2 includes a first driver 21 that drives the third limiting plate 32 to reciprocate and a second driver 22 that drives the fourth limiting plate 33 to reciprocate. Both the first driver 21 and the second driver 22 can be pneumatic cylinders, and the direction of movement of the pneumatic cylinders can be controlled by a solenoid valve.

[0049] The cylinder body of the first actuator 21 can be mounted on the first limiting plate 12 by bolts or other connecting parts. The telescopic end of the first actuator 21 is connected to the third limiting plate 32 through the first connecting seat 211. The connection between the first connecting seat 211 and the telescopic end, as well as between the first connecting seat 211 and the third limiting plate 32, can be achieved through bolts, buckles, pins, or other structures. The cylinder body of the second actuator 22 can be mounted on the second limiting plate 13 by bolts or other connecting parts. The telescopic end of the second actuator 22 is connected to the fourth limiting plate 33 through the second connecting seat 221. The connection between the second connecting seat 221 and the telescopic end, as well as between the second connecting seat 221 and the fourth limiting plate 33, can be achieved through bolts, buckles, pins, or other structures.

[0050] When in use, the sealing nozzle 4 is slid into the first limiting channel 11, and at the same time, the sealing cap 5 connected to the sealing nozzle 4 is slid into the second limiting channel 31. At this time, the protrusion at the end of the sealing cap 5 is located on the side of the third limiting plate 32 and the fourth limiting plate 33 away from the first limiting channel 11. The telescopic ends of the first driver 21 and the second driver 22 extend out simultaneously, respectively driving the third limiting plate 32 and the fourth limiting plate 33 to pull out the protrusion on the sealing cap 5, thereby realizing the disassembly of the sealing cap 5.

[0051] In alternative implementations, such as Figure 1 As shown, the sealing cover opening device may also include a housing 6, which has a side opening 61. The limiting component 1 is connected and fixed to the side opening 61 of the housing 6 by means of screws, welding or integral molding.

[0052] The aforementioned outer shell 6 provides support for the limiting component 1, and the drive mechanism 2 can also be installed inside the outer shell 6, which protects the drive mechanism 2.

[0053] Specifically, the fixed end of the drive mechanism 2 can also be directly mounted on the housing 6, which can also achieve a fixed setting relative to the limit component 1.

[0054] The outer shell 6 can be made of stainless steel, which can ensure the stability of its structure.

[0055] In alternative implementations, such as Figure 5 As shown, a first discharge gap a is provided between the bottom end of the outer shell 6 and the outer pull-out component 3, and a second discharge gap b is provided between the bottom end of the outer shell 6 and the limiting component 1. The second discharge gap b is connected to the first discharge gap a, thereby forming a discharge channel extending from the outer pull-out component 3 to the limiting component 1.

[0056] When the external pull-out component 3 pulls off the sealing cover 5, under the action of gravity, the sealing cover 5 can slide from the second limiting channel 31 into the first discharge gap a. When the outer shell 6 is tilted towards the side opening 61, the sealing cover 5 can continue to slide down and finally be discharged from the outer shell 6 through the second discharge gap.

[0057] In alternative implementations, such as Figure 7 As shown, the sealing cover opening device also includes a recycling box 7 located outside the housing 6. The recycling box 7 is used to receive the sealing cover 5 that falls from the housing 6 after passing through the second discharge gap, so as to collect the sealing cover 5.

[0058] In alternative implementations, such as Figure 2 As shown, a baffle 62 is connected to the side opening 61. The baffle 62 is positioned opposite to the end of the first limiting channel 11 used for entering and exiting the sealing nozzle 4. That is, the baffle 62 is positioned opposite to the first opening 111 of the first limiting channel 11 along the outward pulling direction of the sealing cover 5. There is a first gap c between the baffle 62 and the first limiting channel 11. The first gap c is configured such that when the sealing nozzle 4 enters the first limiting channel 11, the baffle 62 abuts against the end face of the sealing cover 5.

[0059] With the above settings, when the above device is needed to perform the cap removal operation, the end face of the sealing cap 5 abuts against the baffle 62, and the position of the sealing cap 5 is limited along the axial direction of the sealing cap 5. At this time, the sealing nozzle 4 can be aligned with the first limiting channel 11, and the sealing cap 5 can be aligned with the second limiting channel 31, which facilitates the user's operation and speeds up the docking efficiency of the sealing nozzle 4 and the sealing cap.

[0060] In addition, the baffle 62 is located above the drive mechanism 2 and the external pull assembly 3 to avoid obstructing the cap removal operation.

[0061] In alternative implementations, such as Figure 3 As shown, the sealing cap opening device also includes a sensor 8 and a controller. The sensor 8 and the drive mechanism 2 are both electrically connected to the controller. The sensor 8 is used to detect the positioning information of the sealing nozzle 4 or the sealing cap 5. The controller controls the drive mechanism 2 to drive the external pulling component 3 to pull out the sealing cap 5 according to the positioning information.

[0062] When in use, when the sealing nozzle 4 slides into position in the first limiting channel 11, or when the sealing cover 5 slides into position in the second limiting channel 31, the sensor 8 detects the positioning information. The controller controls the solenoid valve to drive the pneumatic cylinder to move according to the positioning information. The cylinder drives the external pulling component 3 to pull out the sealing cover 5, thus completing the action of opening the sealing cover.

[0063] The controller can be a PLC controller or a microcontroller, etc. The control principle of the controller controlling the corresponding actuator based on the received information is a well-known existing technology. To save space, the control principle will not be described in detail here.

[0064] Specifically, sensor 8 can be a photoelectric sensor, pressure sensor, or ultrasonic sensor, etc.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
