Description

Technical Field

[0001] This utility model relates to the field of lid opening, and more specifically, to a lid opening device. Background Technology

[0002] The existing capping and cutting components of the capping device are relatively fixed in design and can only be used for cutting caps of fixed size or shape. For caps of different specifications, parts need to be replaced or the equipment needs to be adjusted, resulting in poor compatibility and adaptability. Utility Model Content

[0003] The main purpose of this utility model is to provide a lid-opening device to solve the problem of poor compatibility and adaptability of lid-opening devices in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a cover opening device is provided, comprising: a frame; a mounting frame movably mounted on the frame; a moving drive component mounted on the frame and driving the mounting frame to move on the frame; a cover opening assembly mounted on the mounting frame and moving under the drive of the mounting frame, the cover opening assembly including a rotatably disposed cover opening member for opening the cover; and a cover pressing assembly movably mounted on the mounting frame and disposed at the cover opening member, the cover pressing assembly pressing against the cover when the mounting frame moves.

[0005] Furthermore, the opening assembly is movably disposed relative to the mounting frame, and the opening device also includes an opening floating assembly, which is drivenly connected to the opening assembly and drives the opening assembly to move relative to the mounting frame. The direction of movement of the opening assembly relative to the mounting frame is parallel to the direction of movement of the capping assembly relative to the mounting frame.

[0006] Furthermore, the opening floating assembly includes: an opening floating member connected to the opening assembly and moving synchronously; a transition member spaced apart from the opening floating member; a first elastic member disposed between the transition member and the opening floating member, which drives the opening floating member to move when the transition member moves; and a floating drive member connected to the transition member and driving the opening assembly to move through the transition member, the first elastic member, and the opening floating member.

[0007] Furthermore, the cover opening assembly also includes: a cover opening drive component; a rotating shaft, which is drivenly connected to the cover opening drive component and rotates under the drive of the cover opening drive component; a connecting block, which is connected to the rotating shaft and rotates synchronously with the rotating shaft, and the cover opening component is disposed on the connecting block, and the cover opening component is eccentrically disposed relative to the rotation axis of the rotating shaft.

[0008] Furthermore, the cover opening assembly also includes a prepositioning member, which is connected to the connecting block and located at the rotation axis of the rotating shaft. The outer peripheral side of the prepositioning member has threads for drilling the cover body, and the connecting block has a first surface facing the cover body. The distance by which the prepositioning member protrudes from the first surface is greater than the distance by which the cover opening member protrudes from the first surface.

[0009] Furthermore, the lid opening device also includes a lid removal assembly, at least a portion of which is located at the end of the prepositioning member and has a through hole through which the prepositioning member passes. When the lid opening assembly moves, the prepositioning member passes through the through hole and is drilled into the lid body. When the lid opening assembly moves in the opposite direction, the lid body on the prepositioning member abuts against the lid removal assembly and disengages from the prepositioning member.

[0010] Furthermore, the cap removal component is floatingly supported on the cap opening component, and the cap opening component is movable up and down relative to the mounting bracket. The travel distance of the cap removal component relative to the cap opening component is greater than the distance of the prepositioning member protruding from the first surface. When the cap opening component descends, the cap removal component is supported on the cap body and separates from the cap opening component. The prepositioning member is drilled into the cap body through the through hole. When the cap opening component rises, the prepositioning member moves above the through hole, and the cap body disengages from the prepositioning member.

[0011] Furthermore, the cap removal assembly includes: a support block disposed above the connecting block and capable of supporting the connecting block; a connecting column disposed longitudinally and connected to the support block; and a cap removal plate connected to the bottom of the connecting column and located below the connecting block, the cap removal plate having a through hole.

[0012] Furthermore, the capping assembly includes: a floating seat supported on the mounting frame; and a capping seat connected to the floating seat, the capping seat having a capping end for abutting against the cap body. When the capping assembly moves, the capping end abuts against the cap body. When the mounting frame continues to move, the capping seat is supported on the cap body and the floating seat separates from the mounting frame.

[0013] Furthermore, the cap seat has a cavity, the cap opening component is located in the cavity, one side of the cavity is the opening side, the end of the opening side is the cap end, the cap end has a bevel structure, the bevel structure abuts against the cap body, and along the direction close to the cap body, the bevel structure is inclined in the direction away from the center of the cavity.

[0014] Furthermore, the inclined structure is continuously arranged along the circumference of the pressure seat; and / or the surface of the inclined structure has a concave-convex structure.

[0015] Furthermore, the mounting bracket has mounting holes, and a floating seat passes through the mounting holes. The floating seat includes a large-diameter section and a small-diameter section connected in sequence. The end of the small-diameter section is connected to the pressure cap seat, and the stepped surface between the large-diameter section and the small-diameter section is supported at the edge of the mounting hole.

[0016] Furthermore, both the stepped surface and the inner wall of the mounting hole are inclined surfaces, and along the direction close to the cover, the inclined surfaces are inclined in the direction close to the axis of the mounting hole.

[0017] Furthermore, the cover opening device also includes: a second guide shaft, which is connected to the mounting frame, and a floating seat is movably disposed on the second guide shaft; and a second elastic member, which passes through the second guide shaft, with its two ends abutting against the mounting frame and the floating seat respectively, and providing the floating seat with an elastic force to move toward the cover.

[0018] Furthermore, a detection component is provided between the floating seat and the mounting bracket. The detection component is used to detect the position of the floating seat in order to determine the pressing state of the pressing assembly.

[0019] Furthermore, the lid opening device also includes a negative pressure component, which is connected to the lid opening component and / or the lid pressing component. The air port of the negative pressure component is located at the lid opening part and draws in negative pressure air when the lid opening part cuts the lid.

[0020] By applying the technical solution of this utility model, the opening assembly and the pressing assembly are mounted on a mounting bracket. The mounting bracket is movably mounted on a frame and can move under the drive of a moving drive component, thereby moving the opening assembly and the pressing assembly mounted thereon, allowing them to approach the cover. Simultaneously, because the pressing assembly is movable relative to the mounting bracket, its position can be adaptively adjusted according to the size of the cover, ensuring that the pressing assembly is always pressed against the cover. This allows the opening component of the opening assembly to rotate and open the pressed cover, fulfilling the need to open the cover. Specifically, the mounting bracket moves the opening assembly and the pressing assembly closer to the cover, causing the pressing assembly to press against the cover. As the mounting bracket moves, the opening component approaches the cover, and then the opening component can rotate to open the cover. The above setup allows for compatibility and adaptability with different types and sizes of lids, enabling the device to open lids of different heights and diameters. The entire process is fully automated, requiring no manual intervention, saving manpower and preventing harm to workers from toxic materials. Attached Figure Description

Detailed Implementation

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0030] To address the problem of poor compatibility and adaptability of existing lid-opening devices, this utility model provides a lid-opening device.

[0031] like Figures 1 to 3The illustrated lid opening device includes a frame 10, a mounting bracket 20, a moving drive component 30, a lid opening assembly 40, and a lid pressing assembly 50. The mounting bracket 20 is movably mounted on the frame 10. The moving drive component 30 is mounted on the frame 10 and drives the mounting bracket 20 to move on the frame 10. The lid opening assembly 40 is mounted on the mounting bracket 20 and moves under the drive of the mounting bracket 20. The lid opening assembly 40 includes a rotatably disposed lid opening member 41 for opening the lid. The lid pressing assembly 50 is movably mounted on the mounting bracket 20 and disposed at the lid opening member 41. When the mounting bracket 20 moves, the lid pressing assembly 50 presses against the lid.

[0032] like Figure 2 As shown, in this embodiment, the opening assembly 40 and the pressing assembly 50 are mounted on the mounting bracket 20. The mounting bracket 20 is movably mounted on the frame 10 and can move under the drive of the moving drive component 30, thereby moving the opening assembly 40 and the pressing assembly 50 mounted thereon, allowing them to approach the cover. Simultaneously, since the pressing assembly 50 is movable relative to the mounting bracket 20, its position can be adaptively adjusted according to the size of the cover, ensuring that the pressing assembly 50 is always pressed against the cover. This allows the opening component 41 of the opening assembly 40 to rotate and open the pressed cover, fulfilling the need to open the cover. Specifically, the mounting bracket 20 moves the opening assembly 40 and the pressing assembly 50 closer to the cover, causing the pressing assembly 50 to press against the cover. As the mounting bracket 20 moves, the opening component 41 approaches the cover, and then the opening component 41 can rotate to open the cover. The above setup allows for compatibility and adaptability with different types and sizes of lids, enabling the device to open lids of different heights and diameters. The entire process is fully automated, requiring no manual intervention, saving manpower and preventing harm to workers from toxic materials.

[0033] like Figures 1 to 3 As shown, this embodiment takes the overall vertical orientation of the lid-opening device as an example. In this case, the moving components such as the mounting bracket 20, the lid-opening assembly 40, and the lid-pressing assembly 50 all move vertically, while the lid is placed below the entire lid-opening device. The lid-pressing assembly 50 moves downward and presses against the top of the lid. Of course, the orientation of the lid-opening device can also be adjusted as needed, and it can also be arranged horizontally. Meanwhile, in this embodiment, the lid-opening component 41 uses a blade or similar component. The blade can penetrate the upper surface of the lid and cut open the upper part of the lid, thereby opening the lid. Alternatively, the lid-opening component 41 can use a screw-on component with protrusions, in which case the lid-opening component 41 can rely on friction to rotate the lid together, thus opening the lid.

[0034] The lid opening device in this embodiment also includes a ball screw. A moving drive component 30 is installed on the frame 10. The moving drive component 30 can be a motor, cylinder, etc. The moving drive component 30 is connected to the mounting frame 20 through the ball screw, and drives the mounting frame 20 to move by rotating the ball screw. The mounting frame 20 can drive the lid opening component 40 and the lid pressing component 50 to rise and fall on the frame 10. The lid pressing component 50 can be driven down by the mounting frame 20 until it presses the lid. After the lid opening component 41 of the lid opening component 40 falls down, it pierces the lid and opens the lid by rotation. The lid pressing component 50 can rise and fall on the mounting frame 20 according to the size of the lid to press the lid of different specifications, which solves the problem of poor compatibility and adaptability of the lid opening device.

[0035] The mounting frame 20 in this embodiment includes mounting plates, which can be multiple and arranged vertically at intervals. This embodiment uses three mounting plates as an example, which are, from top to bottom, a first mounting plate 21, a second mounting plate 22, and a third mounting plate 23. Each of the three mounting plates has openings, through which the cover opening assembly 40 and the cover pressing assembly 50 pass, allowing the cover opening assembly 40 and the cover pressing assembly 50 to be moved by the mounting frame 20 or to move autonomously within the openings of the mounting frame 20.

[0036] like Figure 1 , Figure 2 As shown, in this embodiment, the cap opening component 40 is movably disposed relative to the mounting frame 20. The cap opening device also includes a cap opening floating component 60, which is drivenly connected to the cap opening component 40 and drives the cap opening component 40 to move relative to the mounting frame 20. The direction of movement of the cap opening component 40 relative to the mounting frame 20 is parallel to the direction of movement of the cap pressing component 50 relative to the mounting frame 20. That is to say, in this embodiment, not only is the cap pressing component 50 a floating structure, but the cap opening component 40 also adopts a floating structure. The cap opening component 40 can also move up and down relative to the mounting frame 20. This allows the mounting frame 20 to stop completely after the cap pressing component 50 is pressed onto the cap body. The cap opening floating component 60 then drives the cap opening component 40 to move downward, causing the cap opening member 41 of the cap opening component 40 to insert into the cap body. Then, the cap cutting effect is achieved by rotating the cap opening member 41. Of course, the opening floating component 60 can be omitted, and the opening component 40 can be raised and lowered synchronously with the mounting frame 20. In this case, after the cap pressing component 50 presses the cap, the mounting frame 20 can drive the opening component 40 to continue to descend, so that the opening part 41 can be inserted into the cap to achieve the cap cutting action.

[0037] like Figure 1As shown, the opening floating assembly 60 of this embodiment includes: an opening floating component 61, a transition component 62, a first elastic component 63, and a floating drive component 64. The opening floating component 61 is connected to the opening assembly 40 and moves up and down synchronously. The opening floating component 61 can be a cylinder or other components. The floating drive component 64 is fixedly installed on the first mounting plate 21 of the mounting bracket 20, and the output end of the floating drive component 64 is connected to the transition component 62. The transition component 62 and the opening floating component 61 are spaced apart. The first elastic component 63 is disposed between the transition component 62 and the opening floating component 61. The opening floating component 61, the transition component 62, and the first elastic component 63 are all located between the first mounting plate 21 and the second mounting plate 22. In this way, when the floating drive component 64 drives the transition component 62 to float up and down, the transition component 62 can drive the opening floating component 61 to move up and down through the first elastic component 63, thereby causing the opening floating component 61 to drive the entire opening assembly 40 to move up and down, realizing the up and down floating effect of the opening assembly 40. The presence of the first elastic element 63 makes the opening floating element 61 and the opening assembly 40 have a flexible driving relationship. When the opening assembly 40 moves to the limit position, the driving force of the opening floating element 61 will be converted into the elastic force of the first elastic element 63, thereby avoiding the opening assembly 40 from rising and falling too much.

[0038] like Figure 1 As shown, the opening device of this embodiment also includes a guide shaft 80. There can be multiple guide shafts 80. In this embodiment, two guide shafts are used as an example. The first guide shaft 81 is connected to the mounting bracket 20 and is arranged longitudinally. The opening floating member 61 is provided with a sleeve structure. The sleeve structure is sleeved on the outside of the first guide shaft 81 and can move up and down on the first guide shaft 81. This makes the opening floating member 61 and the opening assembly 40 as a whole only able to move up and down, ensuring the stability and reliability of the movement.

[0039] like Figure 2 As shown, the cover opening assembly 40 of this embodiment further includes: a cover opening drive 42, a rotating shaft 43, a connecting block 44, and a linear bearing; the cover opening drive 42 can be a motor or other components, and the cover opening drive 42 can be floatingly disposed at the opening of the first mounting plate 21; the rotating shaft 43 is drivenly connected to the cover opening drive 42 and rotates under the drive of the cover opening drive 42; the connecting block 44 is connected to the bottom end of the rotating shaft 43 and rotates synchronously with the rotating shaft 43; the cover opening component 41 is disposed on the connecting block 44, and the cover opening component 41 is eccentrically disposed relative to the rotation axis of the rotating shaft 43, that is, the cover opening component 41 can be disposed on the outer side of the connecting block 44, while the rotating shaft 43 can be connected to the center of the connecting block 44, so that the rotation trajectory line of the cover opening component 41 when it rotates under the drive of the connecting block 44 is circular, ensuring the cutting effect on the cover.

[0040] like Figure 2As shown, since the cover opening drive 42 of this embodiment is located at the first mounting plate 21 and the cover opening member 41 is located at the bottom of the whole device, the length of the rotating shaft 43 is set to be relatively long so as to transmit the driving force at the top to the cover opening member 41 at the bottom. Based on this, the rotating shaft 43 will pass through the openings on the second mounting plate 22 and the third mounting plate 23, and will also pass through the cover assembly 50. Therefore, in this embodiment, a linear bearing is provided between the rotating shaft 43 and the cover assembly 50. The linear bearing is sleeved on the outside of the rotating shaft 43 and connected to the cover assembly 50, so that the rotating shaft 43 can move up and down smoothly relative to the cover assembly 50, avoiding jamming and other situations.

[0041] like Figure 2 As shown, the cover opening assembly 40 of this embodiment also includes a pre-positioning member 45. The pre-positioning member 45 is connected to the bottom surface of the connecting block 44 and located at the rotation axis of the rotating shaft 43. The outer periphery of the pre-positioning member 45 has threads for drilling the cover. In this embodiment, the pre-positioning member 45 is a self-tapping screw, so that the connecting block 44 can be rotated using the self-tapping screw. With the downward movement of the cover opening assembly 40, the self-tapping screw can be inserted into the cover body to achieve the fixing effect of the cover body. The connecting block 44 of this embodiment has a first surface facing the cover body. Based on the overall vertical arrangement of this embodiment, the first surface is also the lower surface of the connecting block 44. The distance by which the pre-positioning member 45 protrudes from the first surface is greater than the distance by which the cover opening member 41 protrudes from the first surface, so that the pre-positioning member 45 can contact the cover body first and insert into the cover body. Then, as the cover opening assembly 40 descends, the cover opening member 41 subsequently inserts into the cover body and cuts the cover body open.

[0042] like Figure 3 As shown, the cap opening device of this embodiment also includes a cap removal component 70. At least a portion of the cap removal component 70 is located at the end of the prepositioning member 45 and has a through hole through which the prepositioning member 45 passes. When the cap opening component 40 moves, the prepositioning member 45 passes through the through hole and is drilled into the cap body. When the cap opening component 40 moves in the reverse direction, the cap body on the prepositioning member 45 abuts against the cap removal component 70. The cap opening component 40 continues to move in the reverse direction, causing the cap body to disengage from the prepositioning member 45, thus preventing the cap body from being taken away by the prepositioning member 45 and affecting subsequent cap opening operations, thereby improving the cap opening efficiency of the device.

[0043] like Figure 3As shown, in this embodiment, the cap removal component 70 is buoyantly supported on the cap opening component 40. The cap opening component 40 is movable up and down relative to the mounting bracket 20. The travel distance of the cap removal component 70 relative to the cap opening component 40 is greater than the distance of the prepositioning member 45 protruding from the first surface. Thus, when the cap is cut, as the cap opening component 40 descends, the cap removal component 70 descends synchronously with the cap opening component 40 until the cap removal component 70 abuts against the upper surface of the cap. At this time, the cap removal component 70 is supported on the cap. When the cap opening component 40 continues to descend, the cap removal component 70 will separate from the cap opening component 40. The cap opening component 40 continues to move, causing the prepositioning member 45 to pass through the through hole of the cap removal component 70 and be drilled into the cap. The cap removal component 70 remains basically stationary on the cap. After the opening action is completed, the opening assembly 40 rises. The uncapping assembly 70 is not supported on the opening assembly 40, but on the cap portion cut off by the prepositioning member 45. This allows the opening assembly 40 to lift the uncapping assembly 70 along with the cap portion until the top of the uncapping assembly 70 comes into contact with the capping assembly 50 or other components. At this point, the uncapping assembly 70 can no longer rise, while the opening assembly 40 can continue to rise. Due to the obstruction of the cut-off portion of the cap by the uncapping assembly 70, the cap gradually separates from the prepositioning member 45 until the prepositioning member 45 moves above the through hole. The cut-off portion of the cap then completely separates from the prepositioning member 45, thus achieving automatic separation between the prepositioning member 45 and the cap without manual intervention. This prepares the device for the next cap cutting operation and improves the cap cutting efficiency.

[0044] like Figure 3 As shown, the cap removal assembly 70 of this embodiment includes: a support block 71, a connecting post 72, and a cap removal plate 73. The support block 71 is disposed above the connecting block 44 and can be supported by the connecting block 44. The cap removal assembly 70 is supported by the cap opening assembly 40 through the support block 71. The cap pressing assembly 50 or other components are located above the support block 71. The support block 71 can be configured as a floating flange, etc. The connecting post 72 is arranged longitudinally and connected to the support block 71. The cap removal plate 73 is connected to the bottom of the connecting post 72. The cap removal plate 73 is arranged laterally and located below the connecting block 44. The cap removal plate 73 has a through hole, so that the prepositioning member 45 can be inserted from above the through hole to below the cap removal plate 73, thereby achieving the insertion of the cap. In this embodiment, the axial length, i.e., the longitudinal length, of the connecting post 72 is greater than the longitudinal length of the connecting block 44, so that the travel distance of the cap removal assembly 70 relative to the cap opening assembly 40 is greater than the distance of the prepositioning member 45 protruding from the first surface. When the lid-opening assembly 40 rises after the lid-cutting is completed, the cut lid comes into contact with the lower surface of the lid-removing plate 73, and the lid-removing plate 73 separates the prepositioning member 45 from the lid.

[0045] In this embodiment, the connecting post 72 and the cover opening member 41 can be located on different sides of the connecting block 44 around the perimeter, so that the two do not affect each other and ensure that the cover cutting and cover removal actions can be carried out smoothly.

[0046] like Figure 2 As shown, the capping assembly 50 of this embodiment includes a floating seat 51 and a capping seat 52. The floating seat 51 is supported by the mounting frame 20, allowing the capping assembly 50 to move under the drive of the mounting frame 20. The capping seat 52 is connected to the bottom of the floating seat 51 and has a capping end for abutting against the cap. When the capping assembly 50 moves towards the cap under the drive of the mounting frame 20, the capping end can abut against the cap, press the cap, and assist the capping assembly 40 in opening the cap. When the mounting frame 20 continues to move, the excessive pressure between the capping end and the cap may cause problems such as cap breakage and capping end wear. At this time, the capping seat 52 can support the cap and the floating seat 51 can be separated from the mounting frame 20. In this way, the mounting frame 20 no longer drives the capping assembly 50 to move towards the cap, and the pressure between the capping end and the cap can be relieved. This ensures that the cap can be positioned and pressed while the capping assembly 50 and the cap are not damaged, thus extending the service life of the capping assembly 50. The pressure seat 52 can be configured into a cylindrical shape as needed, so that it corresponds and matches the shape of the cover body.

[0047] like Figure 2 As shown, the cap holder 52 in this embodiment has a cavity, and components such as the connecting block 44, the cap opening component 41, and the cap removal component 70 are all located inside the cavity. One side of the cavity is the open side. In this embodiment, the bottom side of the cavity is the open side. The rotating shaft 43 passes through the cavity from top to bottom and connects with the connecting block 44 inside the cavity. The end of the cavity on the open side is the cap end. In this way, when the cap holder 52 descends, the cap end at the bottom can press against the cap, while the prepositioning component 45 and the cap opening component 41 inside the cavity can move downward to fix the cap and perform cap cutting operations. The cap end in this embodiment has a beveled structure. The beveled structure abuts against the cap. Along the direction close to the cap, the beveled structure is inclined away from the center of the cavity. In this way, caps of different specifications can be adaptively abutted against different positions of the beveled structure, improving the compatibility and adaptability of the cap opening device.

[0048] In this embodiment, the inclined structure can be continuously arranged along the circumference of the cap seat 52 to form a conical surface, ensuring the reliability of the contact between the inclined structure and the cap. The inclined structure can also have concave and convex structures on its surface to increase the friction between the inclined structure and the cap and ensure the reliability of the contact between the inclined structure and the cap. The concave and convex structures can be obtained by creating grooves, knurling, etc. The inclined structure can also be continuously arranged along the circumference of the cap seat 52 while having concave and convex structures, further ensuring the reliability of the contact between the inclined structure and the cap, preventing the cap from rotating during cap cutting and causing cap cutting failure, so that the device can smoothly open caps of different specifications.

[0049] like Figure 2 As shown, the mounting bracket 20 in this embodiment has mounting holes, and the floating seat 51 passes through the mounting holes. In this embodiment, it is set at the third mounting plate 23 at the bottom layer, so the opening on the third mounting plate 23 is the mounting hole. The floating seat 51 includes a large-diameter section and a small-diameter section connected in sequence, forming a stepped surface between the large-diameter section and the small-diameter section. Based on the vertical arrangement in this embodiment, the large-diameter section is located above the small-diameter section, and the bottom end of the small-diameter section is connected to the pressure cap seat 52. The diameter of the large-diameter section is larger than the diameter of the mounting hole, while the diameter of the small-diameter section is smaller than the diameter of the mounting hole, so that the stepped surface can be supported at the edge of the mounting hole, realizing a floating connection between the mounting frame 20 and the pressure cap assembly 50. That is, when the pressure cap assembly 50 is not pressed onto the cover, the mounting frame 20 can drive the floating seat 51 to descend together through the third mounting plate 23. When the pressure cap assembly 50 is pressed onto the cover, the stepped surface of the floating seat 51 separates from the mounting hole, so that the mounting frame 20 moves downward relative to the pressure cap assembly 50, realizing the effect of floating engagement.

[0050] Since the rotating shaft 43 in this embodiment is relatively long, the middle part of the floating seat 51 in this embodiment is hollow, so that the rotating shaft 43 can pass through the floating seat 51, and the linear bearing is disposed between the rotating shaft 43 and the floating seat 51.

[0051] In this embodiment, both the stepped surface and the inner wall of the mounting hole are inclined surfaces. The inclined surfaces are inclined towards the axis of the mounting hole in the direction close to the cover, so that the floating seat 51 can be reliably engaged with the mounting bracket 20. The inclined surface setting allows the stepped surface to automatically center under the inclination of the inclined surface when it is supported at the mounting hole, ensuring accurate and reliable positioning.

[0052] like Figure 1As shown, the opening device of this embodiment further includes: a second guide shaft 82 and a second elastic element; the second guide shaft 82 is connected to the mounting frame 20, and the floating seat 51 is movably disposed on the second guide shaft 82, so that the floating seat 51 can only move up and down under the action of the second guide shaft 82, ensuring the stable and reliable movement of the floating seat 51. The second elastic element can be a spring or other component, which passes through the guide shaft 80. The two ends of the second elastic element abut against the mounting frame 20 and the floating seat 51 respectively, and provide the floating seat 51 with a spring force to move towards the cover, so that the pressing assembly 50 can have a floating space to move away from the cover after pressing against the cover, so that the mounting frame 20 can continue to move downward at this time. The power of the mounting frame 20 will be converted into the spring force of the second elastic element, thereby avoiding excessive pressure on the cover by the pressing assembly 50 and damage to the cover.

[0053] Since both the first guide shaft 81 and the second guide shaft 82 in this embodiment are arranged longitudinally, they can be connected together to form an integral guide shaft 80, which can guide both the cover-opening floating component 61 and the floating seat 51. Of course, the first guide shaft 81 and the second guide shaft 82 can also be arranged separately.

[0054] like Figure 1 As shown, in this embodiment, the second mounting plate 22 is positioned above the third mounting plate 23. Therefore, the large-diameter section of the floating seat 51 is located between the second mounting plate 22 and the third mounting plate 23, and the top end of the second elastic member abuts against the lower surface of the second mounting plate 22. Simultaneously, a longitudinal plate can be added between the second mounting plate 22 and the third mounting plate 23. The longitudinal plate is arranged longitudinally, and its top and bottom ends are connected to the second mounting plate 22 and the third mounting plate 23 respectively, thereby forming a U-shaped structure, which helps to improve the overall structural strength.

[0055] In this embodiment, a detection component is provided between the floating seat 51 and the mounting bracket 20. The detection component is used to detect the position of the floating seat 51 to determine the pressing state of the pressing bracket 50. The detection component can be a sensor or other components. When the detection component detects a predetermined change in the position of the floating seat 51, the detection component determines that the inclined structure of the pressing bracket 50 has abutted against the cover body and completed the pressing action. At this time, the detection component can output a signal to stop the action of the mounting bracket 20, so that the mounting bracket 20 stops moving, avoids excessive movement and damage to the device, and extends the service life of the device.

[0056] like Figure 3As shown, the cap-opening device in this embodiment also includes a negative pressure component 90. The negative pressure component 90 is connected to the cap-opening component 40 and / or the cap-pressing component 50. The air port of the negative pressure component 90 is located at the cap-opening member 41, and it draws in negative pressure air when the cap-opening member 41 cuts the cap, which can remove the debris generated during the cap-cutting process, ensuring that the cap-cutting process is not affected by waste materials and improving the cap-cutting efficiency. In this embodiment, a connection port is provided on the side of the small-diameter section of the floating seat 51, and the negative pressure component 90 is located at the connection port. It can also extend through the interior of the floating seat 51 to the lower cap-opening member 41, so that the channel port is closer to the location where debris is generated, making the debris suction effect of the negative pressure component 90 better.

[0057] The overall operation process of the lid-opening device in this embodiment is as follows:

[0058] The rotating drive component 30 drives the opening assembly 40 and the pressing assembly 50 to descend until the pressing assembly 50 contacts the lid. At this point, the descent continues, and the pressing seat 52 and the floating seat 51 are lifted by the lid. Under the spring force of the second elastic element, the lid is positioned and pressed. At this time, the detection component on the floating seat 51 will output a signal to stop the descent. Next, the floating drive component 64 extends, driving the opening drive component 42 and the connected rotating shaft 43, opening component 41, and pre-positioning component 45 to descend. At the same time as the floating drive component 64 extends, the opening drive component 42 begins to rotate, driving the opening component 41 and the pre-positioning component 45 to rotate together. After the floating drive component 64 extends into place, the pre-positioning component 45 will rotate and screw into the lid. At the same time, the opening component 41 also rotates around the lid and cuts off the top of the lid. During this process, the negative pressure component 90 will be activated to generate negative pressure to suck away the debris generated during the opening.

[0061] 1. This solves the problem of poor compatibility and adaptability of existing lid-opening devices;

[0062] 2.

[0063] 3. The pre-positioning component is inserted into the cover body to fix the cover body in place;

[0064] 4. The cap removal component can automatically separate the cap from the prepositioning component without manual intervention, preparing for the next cap cutting and improving the cap cutting efficiency of the device;
