Detailed Implementation
[0014] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] like Figures 1-4 As shown, a reagent packaging box sealing heat shrinking equipment includes a sealing machine 100 and a heat shrinking machine 200. The sealing machine 100 includes a first frame 110 and a sealing table 120. A sealing heating strip 130 is provided on the sealing table, and a liftable sealing pressure strip 140 is provided above the sealing heating strip. A control mechanism 150 for controlling the lifting and lowering of the sealing pressure strip is provided on the first frame 110. The heat shrinking machine 200 includes a second frame 210 and a conveying device 220. A cover 230 is provided on the conveying device, and a heating furnace channel 240 is formed between the cover and the conveying device. After the reagent packaging box is covered with plastic film, the plastic film is heat-sealed on the sealing machine 100. The opening of the plastic film is placed on the sealing heating strip, and then the sealing pressure strip is pressed down to heat seal. After sealing, the reagent packaging box is transferred to the conveying device of the heat shrink machine 200. The heat shrink machine 200 drives the reagent packaging box through the heating furnace channel 240. The plastic film on the reagent packaging box is heated and shrunk by heating, so that the plastic film tightly wraps the reagent packaging box. Using the sealing machine 100 to heat seal the opening of the plastic film not only has a good sealing effect and effectively prevents the reagent from getting damp or contaminated, but also has high processing efficiency.
[0017] In this embodiment, the control mechanism 150 includes swing arms 151 hinged to both sides of the sealing table and capable of swinging up and down. The free ends of the swing arms are connected to both ends of the sealing strip. A foot pedal 152 is hinged to the lower part of the first frame. A crossbar 153 is provided on the lower side of the sealing table. A pull rod 154 is connected between the crossbar and the foot pedal. Connecting rods 155 passing through the sealing table are respectively connected between the two ends of the crossbar and the two swing arms. Tension springs 156 are connected between the two ends of the crossbar and the bottom surface of the sealing table. The worker can operate the sealing strip with one foot to raise and lower it, which is easy to operate.
[0018] In this embodiment, the sealing table of the sealing machine is higher than the conveying device of the heat shrink machine. A windbreak screen 300 is provided between the sealing machine and the heat shrink machine, and a transition chute 400 passing through the windbreak screen is connected to it. The windbreak screen has a window for the transition chute 400 to pass through. By integrating the sealing and heat shrinking processes, continuous processing of reagent packaging boxes is achieved, eliminating the need for transfer. The sealed packaging box is placed on the transition chute and slides down onto the conveying device of the heat shrink machine. At the same time, the windbreak screen 300 can block the hot air generated by the heat shrink machine, preventing the heat from blowing onto the workers operating the sealing machine.
[0019] In this embodiment, the conveying device 220 adopts a chain conveyor belt. A heating box 250 is located below the conveying device on the second frame. The upper side of the heating box is open, and several electric heating rods 251 are installed inside. An upward-blowing fan 252 is located in the middle of the heating box, and an air inlet gap 253 is left between the bottom of the fan and the bottom of the heating box. The heating chamber of the heat shrink machine adopts a uniform heating mechanism. The upward blowing of the fan and the bottom air inlet design promote the internal circulation of hot air, achieving uniform heating and reducing energy consumption, thereby improving the uniformity of shrinkage.
[0020] In this embodiment, baffles 260 are provided on both sides of the heating box, located between the upper and lower conveyor belts. The design of the baffles reduces the escape of hot air between the upper and lower conveyor belts, thus reducing heat loss.
[0021] In this embodiment, heat-resistant baffles 231 are provided at both ends of the cover to reduce the loss of hot air from the openings at both ends of the heating furnace channel.
[0022] In this embodiment, the two ends of the cover are bolted to both sides of the conveying device, and the two ends of the cover are provided with vertical grooves 232 that are adapted to the bolts. The height of the cover can be adjusted by the cooperation of the vertical grooves and the bolts.
[0023] In this embodiment, the sealing table of the sealing machine 100 is provided with a first temperature controller 160 for controlling the heating temperature of the sealing heating strip, and the second frame of the heat shrink machine 200 is provided with a second temperature controller 270 for controlling the heating temperature of the electric heating rod.

Therefore, this utility model discloses only some numerical values to illustrate the technical solutions of this utility model. Furthermore, the numerical values listed above should not constitute a limitation on the scope of protection of this utility model.
[0025] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integral molding process).
