Description

Technical Field

[0001] This utility model relates to the field of automatic packaging technology, specifically a tension-type bag feeding mechanism and a glass slide packaging machine. Background Technology

[0002] A slide packaging machine is an automated packaging device for glass slides or coverslips. Its main function is to neatly pack slides or coverslips into packaging boxes or containers to ensure their safety and integrity during transportation and storage. This equipment is typically designed to be efficient, precise, and easy to operate, and is suitable for applications in laboratories, medical research, and industrial production.

[0003] When packaging glass slides, different slides have different sizes, so different sized packaging bags are needed to package them. During packaging, the opening of the packaging bag of different sizes needs to be tensioned and controlled in order to fit the glass slide. In existing equipment, hydraulic rods are generally used to suction and open the bag opening. However, it is complicated to operate and make the process cumbersome when using automated equipment to drive the hydraulic rods to adjust the tension of the bag opening. Utility Model Content

[0004] The purpose of this invention is to provide a tension-type bag feeding mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tension-type bag feeding mechanism includes a mounting frame and a conveying mechanism disposed on the mounting frame. The conveying end of the conveying mechanism is provided with a first adsorption element capable of adsorbing the opening end of the packaging bag.

[0007] A support frame is fixedly installed on the mounting frame, and a second adsorption element is slidably arranged on the support frame. The first adsorption element can be aligned with the second adsorption element after being flipped over.

[0008] A reciprocating movable component is mounted on the support frame and connected to the second adsorption component. When the second adsorption component adsorbs and pulls open the other end of the packaging bag opening, the pushing component provided on the support frame acts on the reciprocating movable component to change the size of the packaging bag opening.

[0009] As described above, the tensioned bag feeding mechanism has a connecting frame fixedly installed at the conveying end of the conveying mechanism. One end of the connecting frame is connected to a flipping component fixedly installed on the mounting frame, and the other end is connected to the first adsorption component.

[0010] As described above, the tension-type bag feeding mechanism includes a first hydraulic rod fixedly mounted on the connecting frame, and the movable end of the first hydraulic rod is fixed to a first suction cup slidably mounted on the connecting frame.

[0011] As described above, the tension-type bag feeding mechanism includes a second suction member that is slidably mounted on the support frame. A second hydraulic rod is fixedly mounted on the movable plate, and the movable end of the second hydraulic rod is fixed to a second suction cup that is slidably mounted on the movable plate. The second suction cup can be aligned with the first suction cup after it has been flipped over.

[0012] The tension-type bag feeding mechanism described above includes the following reciprocating moving parts:

[0013] The first conveying wheel is rotatably mounted on the support frame and its rotation is controlled by an intermittent drive component disposed on the support frame;

[0014] The second conveying wheel is rotatably mounted on the support frame and connected to the pushing component;

[0015] The third conveying wheel is rotatably mounted on the support frame and connected to the elastic structure provided on the support frame;

[0016] The conveyor belt is respectively sleeved on the first conveyor wheel, the second conveyor wheel and the third conveyor wheel, and the conveyor belt has protrusions formed on it. The protrusions can be inserted into the limiting groove formed by the movable plate and are slidably connected with the limiting groove.

[0017] As described above, the tensioned bag feeding mechanism includes an intermittent drive component comprising a drive shaft rotatably mounted on the support frame, the drive shaft being driven to rotate by a motor fixedly mounted on the support frame, the drive shaft being connected to a transmission shaft rotatably mounted on the support frame via a Maltese cross mechanism, and the transmission shaft being connected to the first conveyor wheel via a belt.

[0018] As described above, the tensioned bag feeding mechanism includes a lead screw rotatably mounted on the support frame, a first slider threadedly connected to the support frame, and the first slider rotatably connected to the second conveying wheel.

[0019] The tensioned bag feeding mechanism described above: the elastic structure includes a second slider that is rotatably connected to the third conveying wheel, a groove is formed on the support frame for relative sliding of the second slider, a spring is provided in the groove, one end of the spring is connected to the second slider, and the other end is connected to the side wall of the groove.

[0020] A glass slide packaging machine includes the tensioning bag feeding mechanism described in any one of the above.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] After the first adsorption component adsorbs the opening end of the packaging bag on the conveying mechanism, it drives the packaging bag to rotate 90° relative to the conveying mechanism and align with the second adsorption component. At this time, the second adsorption component adsorbs the other end of the packaging bag. By activating the reciprocating moving part, the second adsorption component slides relative to the support frame and stops intermittently after sliding to the end of its stroke. This allows time for the glass slides to be packaged into the bag, avoiding interference between the opening of the packaging bag and the glass slides being packaged. Furthermore, driven by the pushing component, the reciprocating stroke of the second adsorption component is adjusted according to the size of the packaging bag to change the tension of the packaging bag opening. This prevents the packaging bag from being over-opened, causing deformation, or the opening from being insufficient to package the glass slides. This ensures the efficiency and aesthetics of the glass slide packaging and avoids the time wasted in traditional manual adjustment methods due to mold replacement or parameter adjustment.

[0030] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0031] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0032] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0033] Please see Figures 1-6 In this embodiment of the utility model, a tension-type bag feeding mechanism includes a mounting frame 1 and a conveying mechanism 2 disposed on the mounting frame 1. The conveying end of the conveying mechanism 2 is provided with a first adsorption element capable of adsorbing the opening end of the packaging bag.

[0034] A support frame 7 is fixedly installed on the mounting frame 1, and a second adsorption element is slidably arranged on the support frame 7. The first adsorption element can be aligned with the second adsorption element after being flipped.

[0035] A reciprocating movable component is installed on the support frame 7 and connected to the second adsorption component. When the second adsorption component adsorbs and pulls open the other end of the packaging bag opening, the pushing component provided on the support frame 7 acts on the reciprocating movable component to change the size of the packaging bag opening.

[0036] It should be noted that the opening of the packaging bag conveyed by the conveying mechanism 2 faces the conveying direction, and the packaging bag is conveyed one by one.

[0037] In this embodiment, after the first adsorption member adsorbs the opening end of the packaging bag on the conveying mechanism 2, the first adsorption member drives the packaging bag to rotate 90° relative to the conveying mechanism 2 and align it with the second adsorption member. At this time, the second adsorption member adsorbs the other end of the packaging bag. By activating the reciprocating moving part, the second adsorption member is driven to slide relative to the support frame 7 and stops intermittently after sliding to the end of the stroke. This allows time for the glass slides to be packed into the bag, avoiding interference between the opening of the packaging bag and the glass slides being packed into the bag. Furthermore, driven by the pushing component, the stroke of the reciprocating movement of the second adsorption member is adjusted according to the size of the packaging bag to change the tension of the packaging bag opening. This prevents the packaging bag from being over-opened, causing deformation, or the opening from being insufficient to pack the glass slides, thereby ensuring the efficiency and aesthetics of the glass slide packaging and avoiding the time wasted in the traditional manual adjustment method due to changing molds or adjusting parameters.

[0038] As a further embodiment of this invention, a connecting frame 3 is fixedly installed at the conveying end of the conveying mechanism 2. One end of the connecting frame 3 is connected to a flipping component fixedly installed on the mounting frame 1, and the other end is connected to the first adsorption component.

[0039] The first adsorption component includes a first hydraulic rod 5 fixedly mounted on the connecting frame 3, and the movable end of the first hydraulic rod 5 is fixed to a first suction cup 4 slidably mounted on the connecting frame 3.

[0040] It should be noted that the flipping component includes a rotating shaft 6 rotatably mounted on the mounting frame 1. The rotating shaft 6 is fixed to the connecting frame 3, and the rotation of the rotating shaft 6 is controlled by a motor mounted on the mounting frame 1 to ensure that the rotating shaft 6 rotates 90° each time. The specific motor control method for the rotating shaft 6 is existing technology.

[0041] As a further embodiment of this utility model, the second suction member includes a movable plate 10 slidably disposed on the support frame 7, a second hydraulic rod 9 is fixedly mounted on the movable plate 10, and the movable end of the second hydraulic rod 9 is fixed to a second suction cup 8 slidably disposed on the movable plate 10, and the second suction cup 8 can be aligned with the first suction cup 4 after being flipped over.

[0042] The reciprocating moving part includes:

[0043] The first conveying wheel 11 is rotatably mounted on the support frame 7 and its rotation is controlled by an intermittent drive component provided on the support frame 7;

[0044] The second conveying wheel 12 is rotatably mounted on the support frame 7 and connected to the pushing component;

[0045] The third conveying wheel 13 is rotatably mounted on the support frame 7 and connected to the elastic structure provided on the support frame 7;

[0046] The conveyor belt 14 is respectively sleeved on the first conveyor wheel 11, the second conveyor wheel 12 and the third conveyor wheel 13, and the conveyor belt 14 has a protrusion 1401 formed on it. The protrusion 1401 can be inserted into the limiting groove formed by the movable plate 10 and slidably connected with the limiting groove.

[0047] As a further embodiment of this utility model, the intermittent drive includes a drive shaft 16 rotatably mounted on the support frame 7. The drive shaft 16 is driven to rotate by a motor 15 fixedly mounted on the support frame 7. The drive shaft 16 is connected to a transmission shaft 17 rotatably mounted on the support frame 7 via a Maltese cross mechanism 18, and the transmission shaft 17 is connected to the first conveyor wheel 11 via a belt 19.

[0048] In detail, after the second suction cup 8 adsorbs the packaging bag, the motor 15 is started. The output shaft of the motor 15 is fixed to the drive shaft 16, so that when the output shaft rotates, it drives the drive shaft 16 to rotate synchronously. At this time, under the transmission of the Maltese cross mechanism 18, the drive shaft 16 rotates one revolution, and the transmission shaft 17 can rotate 90° to meet the requirement of intermittent rotation of the transmission shaft 17. Under the transmission of the belt 19, the first conveyor wheel 11 is driven to rotate and the transmission ratio changes, so that the movable plate 10 can stop when it moves to the end of the stroke, so as to reserve time for the glass slide to be packaged into the bag and avoid interference between the opening of the packaging bag and the glass slide entering the bag.

[0049] When the first conveyor wheel 11 rotates, it drives the conveyor belt 14 to rotate in cooperation with the second conveyor wheel 12 and the third conveyor wheel 13. When the conveyor belt 14 rotates, the protrusions 1401 on it squeeze the movable plate 10. Under the restriction of the guide block 1001, when the conveyor belt 14 completes one revolution, the movable plate 10 completes a set of reciprocating movements on the support frame 7. When the conveyor belt 14 completes half a revolution, the movable plate 10 moves to the end of the stroke. At this time, the conveyor belt 14 stops rotating to meet the requirement of intermittent movement of the movable plate 10.

[0050] As a further embodiment of this invention, the pushing assembly includes a lead screw 21 rotatably mounted on the support frame 7, and a first slider 20 slidably connected to the support frame 7 is threaded onto the lead screw 21. The first slider 20 is rotatably connected to the second conveying wheel 12.

[0051] The elastic structure includes a second slider 22 rotatably connected to the third conveying wheel 13. A groove is formed on the support frame 7 for the second slider 22 to slide relative to it. A spring 23 is provided in the groove. One end of the spring 23 is connected to the second slider 22, and the other end is connected to the side wall of the groove.

[0052] When adjusting the tension of the packaging bag, it is necessary to change the distance between the first conveyor wheel 11 and the third conveyor wheel 13. By controlling the rotation of the lead screw 21, the distance between the second conveyor wheel 12 and the first and third conveyor wheels 11 can be adjusted so that when the tension of the conveyor belt 14 on the third conveyor wheel 13 is less than the elastic force of the spring 23, the third conveyor wheel 13 moves away from the first conveyor wheel 11 under the elastic action of the spring 23, thereby changing the distance between the first and third conveyor wheels 11 and thus changing the stroke of the movable plate 10 to adjust the tension of the opening of different sized packaging bags.

[0053] A glass slide packaging machine includes the tensioning bag feeding mechanism described in any one of the above.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
