Description
Technical Field
[0001] This application relates to the field of pharmaceutical packaging production technology, and in particular to a heat shrink film packaging machine for pharmaceutical packaging boxes. Background Technology
[0002] In the pharmaceutical production process, heat shrink film packaging machines are used to package the product. These machines shrink the film through heating, tightly wrapping the product. There are various types of heat shrink film packaging machines. Based on the heating method, they can be divided into hot air circulation type, quartz tube heating type, and stainless steel heating tube type; based on the conveying method, they include roller type, mesh belt type, and chain type; in terms of automation, there are semi-automatic and fully automatic models. In pharmaceutical packaging, the heat shrink film must meet hygiene standards and possess properties such as dustproof, moisture-proof, and tamper-proof. Simultaneously, the material must be safe and harmless, complying with food or drug contact regulations.
[0003] Existing heat shrink film packaging machines lack fixing devices when packaging multiple small medicines at the same time. During multiple processes, the medicines may not be aligned before packaging, resulting in incomplete packaging or abnormalities. This often requires rework and reduces production efficiency. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a heat shrink film packaging machine for pharmaceutical packaging boxes, which overcomes the deficiencies of existing technologies. It aims to solve the problem that existing heat shrink film packaging machines lack fixing devices when packaging multiple small pharmaceuticals in a unified manner. This can lead to situations where pharmaceuticals are not aligned before packaging, resulting in incomplete packaging or abnormalities. Consequently, rework is often required, leading to a decrease in production efficiency.

The heat preservation mechanism includes a soft cloth curtain, and a fixing member is provided at the top of the soft cloth curtain. The fixing member is fixedly connected to the heating furnace.
[0014] By adopting the above technical solution and setting up a heat preservation mechanism, the overall heat preservation performance of the heating furnace can be improved during use, further reducing heat loss, improving thermal efficiency, and reducing energy consumption.
[0015] As a preferred technical solution of this application, multiple sets of temperature sensors are provided on the inner wall of the heating furnace and the bottom of the conveyor roller, and the multiple sets of temperature sensors are electrically connected to the control panel.

[0018] By adopting the above technical solution and setting up an observation window, staff can easily observe the efficiency of heat sealing from the outside, thus improving the practicality of the device.
[0019] As a preferred technical solution of this application, a connecting plate is provided at the connection between the sealing conveyor belt and the support base, and the connecting plate is rotatably connected to the sealing conveyor belt.
[0020] By adopting the above technical solution and setting a connecting plate, the stability of the connection between the sealing conveyor belt and the support can be improved, making the transmission of medicines more stable and improving the stability during use.
[0021] The beneficial effects of this application are:
[0022] 1. By setting up a feeding conveyor belt, during use, the staff places the medicine on the top of the feeding conveyor belt, which is then conveyed to the bottom of the film rolling mechanism for film covering.
