Description

Technical Field

[0001] This utility model relates to the technical field of automatic sealing film machines, and in particular to an automatic sealing film machine suitable for dispensing tubes of different specifications. Background Technology

[0002] The automatic sealing film applicator is an automated device used for sealing dispensing tubes in fields such as biological experiments, medical testing, and chemical reagent storage. Its core function is to automatically wrap and seal the dispensing tube with sealing film through a mechanical structure, replacing traditional manual sealing operations. In practice, the operator places the dispensing tube containing the sample or reagent upside down in the instrument's inlet. The instrument fixes the dispensing tube using a built-in positioning mechanism. Then, according to preset parameters, the sealing component drives the sealing film to rotate around the opening of the dispensing tube, completing the wrapping, application, and cutting of the film material, ultimately sealing the dispensing tube.

[0003] However, the clamping structure of existing automatic sealing film machines is mostly of fixed size, which cannot flexibly adjust the clamping range according to the specifications of the dispensing tubes, resulting in only being able to adapt to a single specification of dispensing tubes; if different specifications need to be processed, it is necessary to frequently change special clamping accessories or even equipment, which is cumbersome and affects efficiency.

[0004] Therefore, this utility model proposes an automatic sealing film machine suitable for dispensing tubes of different specifications to solve the above problems. Utility Model Content

The adaptive action component is assembled on the inner arc surface of the middle telescopic plate. An outer peripheral gear that meshes with the driving component is assembled on the outer periphery of the upper driving plate. The driving component drives the upper driving plate to rotate through the outer peripheral gear, thereby moving the middle telescopic plate and the adaptive action component.

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Reference Figures 1-4 As shown, the first embodiment of this utility model provides an automatic sealing film instrument suitable for dispensing tubes of different specifications, including an automatic sealing film instrument body and an adaptive clamping mechanism. The adaptive clamping mechanism is assembled at the sample inlet of the automatic sealing film instrument body and is used to clamp the dispensing tube portion that is inverted into the sample inlet of the automatic sealing film instrument body. The automatic sealing film instrument automatically seals dispensing tubes of different specifications.

[0021] The adaptive clamping mechanism includes a clamping component 100, an adaptive action component 200, and a driving component 300. The clamping component 100 includes an upper driving plate 101, a middle telescopic plate 102, and a lower limiting plate 103 stacked on top of each other. The middle telescopic plate 102 is engaged with the upper driving plate 101 and the lower limiting plate 103 and is guided and driven by the upper driving plate 101 and the lower limiting plate 103. A motor mounting plate 400 for fixing the driving component 300 is mounted on the side of the lower limiting plate 103 opposite to the middle telescopic plate 102. The adaptive action component 200 is mounted on the inner arc surface of the middle telescopic plate 102. An outer peripheral gear 104 that meshes with the driving component 300 is mounted on the outer periphery of the upper driving plate 101. The driving component 300 drives the upper driving plate 101 to rotate through the outer peripheral gear 104 to move the middle telescopic plate 102 and the adaptive action component 200 to clamp different specifications of packaging tubes.

[0022] Furthermore, the size of the injection port is larger than the maximum outer diameter of the dispensing tube that can be held by the multiple sets of adaptive action components 200.

[0023] Reference Figure 2 and Figure 3 As shown, there are multiple central telescopic plates 102, which are distributed circumferentially at equal intervals. Adjacent central telescopic plates 102 are attached to each other, and an arc-shaped drive block 1022 is arranged on the side of the central telescopic plate 102 facing the upper drive plate 101.

[0024] Furthermore, a columnar limiting plate 1021 is installed through the surface of the central telescopic plate 102, and the columnar limiting plate 1021 extends downward through the lower surface of the central telescopic plate 102.

[0025] Reference Figure 3 As shown, the surface of the upper drive plate 101 is provided with multiple strip-shaped drive arc grooves 1011, and the multiple strip-shaped drive arc grooves 1011 correspond to multiple middle telescopic plates 102, and the arc-shaped drive block 1022 is engaged in the strip-shaped drive arc grooves 1011.

[0026] Reference Figure 2 As shown, the surface of the lower limiting plate 103 has multiple strip-shaped limiting arc grooves 1031, and the multiple strip-shaped limiting arc grooves 1031 correspond to multiple middle telescopic plates 102. The column-shaped limiting plate 1021 is engaged in the strip-shaped limiting arc grooves 1031.

[0027] Furthermore, the drive component 300 includes a drive motor 301 mounted on the motor mounting plate 400 and a cylindrical gear 302 mounted on the output end of the drive motor 301. The output end of the drive motor 301 mounted on the motor mounting plate 400 faces the upper drive plate 101. The cylindrical gear 302 meshes with the outer peripheral gear 104. The drive motor 301 drives the cylindrical gear 302 to rotate, thereby driving the outer peripheral gear 104 and the upper drive plate 101 to rotate. The rotating upper drive plate 101 rotates through the arc-shaped drive block 1022. However, under the guidance of the cylindrical limiting plate 1021 and the strip-shaped limiting arc groove 1031, the arc-shaped drive block 1022 rotates inward along the groove trajectory of the strip-shaped limiting arc groove 1031. The clamping range enclosed by the multiple middle telescopic plates 102 extends and retracts to adapt to different specifications of dispensing tubes.

[0028] Reference Figure 4 As shown, the adaptive action component 200 includes an arc-shaped connector 201 connected to the inner arc of the central telescopic plate 102, a U-shaped rod 202 assembled on the connector 201, a positioning vertical rod 203 sleeved on the U-shaped rod 202, and an action component engaged with the positioning vertical rod 203. The action component and the surface of the positioning vertical rod 203 are rotatably connected. The functional components include a sleeve 204, an arc-shaped functional substrate 205 mounted on the surface of the sleeve 204, and a thick silicone layer 206 attached to the side of the arc-shaped functional substrate 205 facing away from the sleeve 204.

[0029] Furthermore, the U-shaped rod 202 and the positioning vertical rod 203 are arranged parallel to the axis of the clamping component 100. The arc-shaped action plate 205 is made of thermoplastic elastomer TPE material. Under the action of external force, it can produce slight deformation to adapt to the outer circumferential curvature of different specification dispensing tubes. When the external force disappears, it can quickly return to its original shape. This avoids the dispensing tube from being deformed due to excessive rigidity. It can also increase the contact area with the dispensing tube through its own deformation, so that the action component 200 has sufficient clamping force and clamping surface acting on the surface of the dispensing tube to achieve the purpose of clamping the dispensing tube.

[0030] Working principle: When the dispensing tube to be sealed is inverted and inserted into the inlet of the automatic sealing film instrument, the adaptive clamping mechanism starts working. The drive motor 301 of the drive component 300 outputs power, driving the cylindrical gear 302 to rotate. Since the cylindrical gear 302 meshes with the outer peripheral gear 104 on the outer periphery of the upper drive plate 101, it drives the upper drive plate 101 to rotate synchronously. At this time, the strip-shaped drive arc groove 1011 on the surface of the upper drive plate 101 rotates with it, and the arc-shaped drive block 1022 of the middle telescopic plate 102, which is engaged in the groove, is constrained by the groove trajectory of the strip-shaped limiting arc groove 1031, forming a guide. This causes multiple circumferentially distributed middle telescopic plates 102 to move inward synchronously along the arc trajectory of the strip-shaped limiting arc groove 1031, and the clamping range they form gradually shrinks until it matches the outer diameter of the current dispensing tube.

[0031] Among them, the adaptive action component 200, which is assembled on the inner arc surface of the central telescopic plate 102, synchronously approaches the dispensing tube. The arc-shaped action base plate 205 undergoes slight deformation under the push of external force, and in conjunction with the thick silicone layer 206 on the surface, it closely adheres to the outer peripheral wall of the dispensing tube. The deformation of the arc-shaped action base plate 205 and the thick silicone layer 206 compensates for the curvature difference of dispensing tubes of different specifications, increases the clamping contact area, and provides stable clamping force by means of its own elasticity, so as to avoid the dispensing tube being deformed or loosened by pressure.

[0032] After the adaptive clamping mechanism securely clamps the dispensing tube, the automatic sealing film machine body starts the automatic sealing program according to the preset dispensing tube specifications and the set number of sealing film wrapping turns. The sealing mechanism at the sample inlet completes the wrapping and sealing of the sealing film, ultimately achieving efficient and stable sealing of dispensing tubes of different specifications.

[0033] Throughout the process, the power transmission of the drive component 300, the extension and retraction adjustment of the central telescopic plate 102, and the deformation adaptation of the adaptive component 200 work together to ensure that the automatic sealing film machine can quickly respond to the clamping requirements of different specifications of dispensing tubes, providing a reliable structural foundation for subsequent automatic sealing.
