Description

Technical Field

[0001] This utility model relates to the field of grafting film production technology, and in particular to a heating device for grafting film with gapless temperature control. Background Technology

[0002] In modern agricultural production, grafting film is often used when propagating plants by grafting. When used, it can tighten the cut of the plant.

[0003] In the production of grafting film, stirring devices are often used to stir the grafting film masterbatch. However, existing stirring devices are not convenient for quickly and thoroughly stirring the masterbatch, requiring more time to stir. Furthermore, traditional heating methods result in uneven heating of the masterbatch, causing some of the masterbatch to cool and solidify, which affects the stirring process. Therefore, a heating device with seamless temperature control for grafting film is provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a seamless temperature-controlled heating device for grafting films. While stirring the grafting film masterbatch, a temperature sensor detects the temperature of the masterbatch and transmits the temperature information to a controller. The controller then controls the heating temperature of the radiant heating tube to achieve constant temperature heating and stable temperature control, thus enabling uniform heating of the masterbatch. This helps improve the processing effect of the grafting film masterbatch and overcomes the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] As a further improvement of this utility model, the interlayer between the inner tube and the outer cylinder is filled with a nano-radiation resistant heat insulation board.

[0008] As a further embodiment of this utility model: the stirring mechanism includes a servo motor installed on the lower end face of the outer cylinder, the output end of the servo motor extends into the interior of the outer cylinder and is connected to a rotating rod, a connecting sleeve is fixed to the top of the rotating rod, and two L-shaped stirring rods are symmetrically fixed to the outer wall of the connecting sleeve.

[0009] As a further improvement of this utility model: a scraper is fixed on one side of the vertical section of each of the two L-shaped stirring rods, and both scrapers slide in contact with the inner wall of the inner tube.

[0010] As a further improvement of this utility model: the bottom ends of the vertical sections of the two L-shaped stirring rods are each connected to a horizontal rod, and the top of the two horizontal rods near the rotating rod is fixed with a vertical rod.

[0011] As a further improvement of this utility model, a spiral stirring blade is fixed on the outer wall of the rotating rod and below the connecting sleeve.

[0012] As a further embodiment of this utility model: the bottom end of the outer cylinder is provided with an arc-shaped discharge port, and an arc-shaped sleeve is fixed on the lower end face of the outer cylinder and on one side of the arc-shaped discharge port. An arc-shaped baffle is slidably inserted inside the arc-shaped sleeve.
