Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to packaging equipment for cervical sampling swabs. Background Technology

[0002] In the medical device industry, the packaging of cervical sampling swabs is a crucial step in ensuring product safety and efficacy. Existing cervical sampling swab packaging equipment typically uses a cylinder-driven sealing device for thermoforming. While this method achieves basic sealing functionality, it has some significant shortcomings in practical applications.

[0003] First, the pressure applied directly by the cylinder often lacks flexible adjustment capabilities. During the heat sealing process, excessive pressure may damage the packaging film or deform the sampling swab, thus affecting the product's usability and safety. Conversely, insufficient pressure may result in a weak heat seal, leading to leakage and contamination risks.

[0004] Secondly, existing technologies lack effective cushioning structures. During the application of pressure by the cylinder, the lack of a cushioning mechanism can cause severe impacts in the direct contact between the heat-sealing device and the packaging film. This not only affects the sealing quality but may also lead to equipment wear and frequent malfunctions. Furthermore, if the pressure generated during the heat-sealing process is not properly controlled, it may adversely affect the physical properties of the packaging film, resulting in poor heat-sealing performance. Utility Model Content

[0005] The purpose of this invention is to provide a cervical sampling swab packaging device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cervical sampling swab packaging device, comprising:

[0007] frame;

[0011] A support platform, which is mounted on the frame and corresponds to the position of the sealing device;

[0012] The guide roller is symmetrically mounted on the upper surface of the frame, and the guide roller is rotatably connected to the support frame.

[0013] Preferably, the elastic clamping device includes:

[0014] Connecting rod, which is slidably inserted into the frame;

[0017] A limiting ring is fixedly sleeved on the connecting rod, and the limiting ring is used to support the plastic sealing device.

[0018] Preferably, the elastic clamping device further includes:

[0032] The technical effects and advantages of this utility model are as follows:

[0033] This invention utilizes a combination of an elastic clamping device and a lifting device. The lifting device facilitates the downward movement of the elastic clamping device, which in turn moves the sealing device towards the support platform.

The elastic clamping device cushions the downward heat-pressing of the sealing device, resulting in a better heat-sealing effect. The elastic support of the clamping device provides a more uniform and stable pressure distribution during heat sealing, avoiding the poor heat-sealing caused by excessive or insufficient pressure in traditional technologies. This significantly improves the strength and sealing of the seal, ensuring the safety of the sampling swab, reducing the risks to operators during heat sealing, enhancing overall operational safety, and ensuring safe operation under high temperature and high pressure conditions.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This utility model provides, for example Figure 1-5 The cervical swab packaging equipment shown includes: a frame 1; multiple elastic clamping devices 2 slidably connected to the frame 1; a lifting device 3 installed at the bottom of the frame 1, used to drive the lifting movement of the elastic clamping devices 2; a sealing device 4 slidably connected to the elastic clamping devices 2, used for heat sealing the packaging paper; a support platform 5 installed on the frame 1, corresponding to the sealing device 4, facilitating the carrying of the packaging bag; and guide rollers 6, with support frames fixedly and symmetrically installed on the upper surface of the frame 1, the guide rollers 6 rotatably connected to the support frames. The vertical arrangement of the two guide rollers 6 facilitates the guidance of the upper and lower packaging films, allowing the upper and lower packaging films to be stacked together for swab packaging. The lifting device 3 facilitates the lifting movement of the packaging paper. The elastic clamping device 2 descends, causing the sealing device 4 to move towards the support platform 5. This allows the sealing device 4 to heat-seal the upper and lower packaging films, encapsulating the cervical sampling swab within the two layers of film. The elastic clamping device 2 cushions the downward heat-pressing of the sealing device 4, resulting in a better heat-sealing effect. The elastic support of the elastic clamping device 2 provides a more uniform and stable pressure distribution during heat sealing, avoiding poor sealing caused by excessive or insufficient pressure in traditional techniques. This significantly improves the strength and sealing of the seal, ensuring the safety of the sampling swab, reducing the risk to operators during heat sealing, enhancing overall operational safety, and ensuring safe operation under high temperature and high pressure conditions.

[0042] The elastic compression device 2 includes: a connecting rod 21, which is slidably inserted into the frame 1; a limiting mechanism 22, which is slidably sleeved on the top of the connecting rod 21; a spring 23, which is sleeved on the outside of the connecting rod 21 and is used to elastically compress the sealing device 4; and a limiting ring 24, which is fixedly sleeved on the connecting rod 21 and is used to support the sealing device 4. The elastic pressing device 2 also includes a guide cylinder 25, which is slidably inserted into the connecting rod 21 and is fixedly installed on the frame 1. The sliding sleeve between the connecting rod 21 and the guide cylinder 25 facilitates the limiting of the lifting and lowering movement of the connecting rod 21, making the lifting and lowering movement of the connecting rod 21 more stable. The spring 23 facilitates the elastic support of the insert plate 41, allowing the sealing device 4 to perform elastic heat pressing on the packaging film. The limiting ring 24 facilitates the bearing of the position of the insert plate 41, preventing the insert plate 41 from moving excessively downward under the elastic pressure of the spring 23, making the position of the insert plate 41 relative to the connecting rod 21 more stable.

[0043] Specifically, the limiting mechanism 22 includes: a limiting pressure ring 221, which is slidably sleeved with the connecting rod 21 and is used to compress the spring 23; and a limiting slide post 222, which is fixedly installed inside the limiting pressure ring 221. A vertically formed groove 201 is provided on the connecting rod 21, and multiple limiting grooves 202 are formed on one side of the inner wall of the groove 201. The limiting slide post 222 cooperates with the inner cavity of the limiting groove 202. The limiting pressure ring 221 facilitates the adjustment of the position of the limiting slide post 222 relative to the axis of the connecting rod 21 under the limiting of the groove 201, thereby compressing the spring. Further compression of spring 23 increases the elastic force of spring 23. The limiting groove 202 is L-shaped. When the position of the limiting pressure ring 221 relative to the connecting rod 21 is adjusted to a suitable state, the limiting pressure ring 221 is rotated, causing the limiting pressure ring 221 to drive the limiting slide 222 to rotate around the axis of the connecting rod 21. Through the reverse support force of spring 23, the limiting slide 222 is engaged with the end of the inner cavity of the limiting groove 202, thereby realizing the position limitation of the limiting slide 222 and the limiting pressure ring 221, so as to realize the limitation after the position of the limiting pressure ring 221 is adjusted, making the use of the limiting mechanism 22 more flexible.

[0044] The lifting device 3 includes: a cylinder 31, which is fixedly installed on the lower surface of the frame 1; and a lifting plate 32, which is connected to the output end of the cylinder 31. The lifting plate 32 is fixedly connected to the connecting rod 21. The cylinder 31 is used as a power source to drive the lifting plate 32 to move up and down, so that the lifting plate 32 can drive the lifting of multiple connecting rods 21 simultaneously.

[0045] The sealing device 4 includes: an insert plate 41, which is slidably inserted into the connecting rod 21; and a heat sealing mechanism 42, which is installed at the bottom of the insert plate 41 and is easily driven to move the insert plate 41 up and down by means of the elastic pressing device 2. The heat-sealing mechanism 42 includes: a mounting plate 421, which is fixedly installed on the bottom of the insert plate 41; a first heat-sealing protrusion 422 and a second heat-sealing protrusion 423, both of which are connected to the lower surface of the mounting plate 421. The first heat-sealing protrusion 422 and the second heat-sealing protrusion 423 are arranged opposite to each other. Both the first heat-sealing protrusion 422 and the second heat-sealing protrusion 423 are arranged in a comb shape, and the openings of the first heat-sealing protrusion 422 and the second heat-sealing protrusion 423 face opposite directions. This allows the packaging film to shrink into a U-shape when the first heat-sealing protrusion 422 heat-presses and seals the upper and lower packaging films. The front opening is not sealed, leaving an opening for the cervical sampling swab to enter. Then, after the cervical sampling swab enters, the reserved opening is sealed by the heat-pressing of the second heat-sealing protrusion 423.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
