Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable packaging technology, specifically a fruit and vegetable packaging machine and its packaging method. Background Technology

[0002] Fruits and vegetables are a general term for edible fruits and vegetables, and are a category of food, as opposed to meat. Packaging refers to the containers, materials, and auxiliary materials used to protect products, facilitate storage and transportation, and promote sales during the distribution process, according to certain technical methods. It also refers to the operational activities of applying certain technical methods in the process of using containers, materials, and auxiliary materials to achieve the above objectives. Items that hold goods that do not enter the distribution field cannot be called packaging; they can only be called "parcels," "boxes," "containers," etc. This is because, in addition to the function of containing and packaging goods, the important role of packaging is to enhance the appearance of the goods and attract the attention of the consumer.

[0003] The development of the packaging industry and technology has driven the formation of packaging science research and packaging discipline. Packaging science encompasses knowledge from physics, chemistry, biology, humanities, and art, belonging to the interdisciplinary group of comprehensive sciences. It organically absorbs and integrates new theories, materials, technologies, and processes from different disciplines, addressing comprehensive issues in the circulation process, such as commodity protection, storage, transportation, and sales promotion, from a systems engineering perspective. Fruit and vegetable packaging typically uses film wrapping for both fixation and preservation. However, traditional fruit and vegetable film packaging has a rigid structure, limited functionality, and particularly unsatisfactory wrapping efficiency and effectiveness. Therefore, the inventor has proposed a fruit and vegetable packaging machine, taking into account various factors. Summary of the Invention

[0004] The technical problem to be solved by this invention is that traditional fruit and vegetable packaging is inefficient and the coating effect is not ideal.

[0005] This invention provides the following technical solution:

[0006] A fruit and vegetable packaging machine includes a housing, within which are a horizontal clamping and covering mechanism and a vertical clamping and covering mechanism. The horizontal clamping and covering mechanism clamps both sides of the fruit and vegetables and covers them laterally, and can also drive the fruit and vegetables into the vertical clamping and covering mechanism. The vertical clamping and covering mechanism can intersect with the horizontal clamping and covering mechanism and vertically cover the fruit and vegetables. A thermoplastic shaping mechanism is provided at the top of the housing, which thermoplastic shapes the film covering the outside of the fruit and vegetables.

[0007] During operation, fruits and vegetables enter the machine casing. First, the horizontal clamping and covering mechanism clamps both sides of the fruits and vegetables and covers them horizontally. Then, the fruits and vegetables are clamped into the vertical clamping and covering mechanism, where the vertical clamping and covering mechanism and the horizontal clamping and covering mechanism cross-cover the fruits and vegetables. After the covering is completed, the film covering the outside of the fruits and vegetables is thermo-shaped by the thermoplastic shaping mechanism, thus completing the fruit and vegetable packaging.

[0008] As a further embodiment of the present invention: the horizontal clamping and covering mechanism includes a telescopic frame, a horizontal clamping arm assembly, a horizontal pin, a clamping support, and a clamping frame;

[0009] The telescopic frame is fixed to the inner wall of the machine housing. The horizontal clamping arm assembly is installed on the telescopic frame. The horizontal clamping arm assembly includes two horizontal clamping arms, which are hinged together in the middle by a horizontal pin. The front ends of the two horizontal clamping arms are respectively connected to clamping supports. The tail ends of the two horizontal clamping arms are connected to a clamping power mechanism. A transverse film conveying roller is provided in the machine housing corresponding to the clamping support, and a covering film is wrapped around the transverse film conveying roller.

The front ends of the two vertical clamping arms are respectively connected to clamping supports. The tail ends of the two vertical clamping arms are connected to a clamping power mechanism. A vertical film conveying roller is provided inside the housing corresponding to the clamping support. A covering film is wound on the vertical film conveying roller.

[0012] As a further embodiment of the present invention: a feeding hopper is provided at the top of the machine casing, and a lifting covering tray is provided inside the machine casing corresponding to the bottom of the feeding hopper.

[0013] As a further embodiment of the present invention: the bottom of the feed hopper is provided with a slow-release mesh bag.

[0014] As a further embodiment of the present invention: the lifting wrapping tray includes a tray, the bottom of which is fixed to the bottom of the machine housing by a lifting cylinder.

[0015] As a further embodiment of the present invention: the tray is provided with a flexible support pad; the clamping support is provided with a flexible clip pad;

[0016] As a further embodiment of the present invention: a thermoplastic lamp is provided on the side wall of the housing corresponding to the vertical clamping and covering mechanism to perform film thermoplastic shaping on the cross-wrapped fruits and vegetables;

[0017] As a further embodiment of the present invention: the coating film is provided with ribs on both sides, and the side of the coating film is connected to the ribs by connecting strips; the coating film is provided with uniformly distributed holes in the middle to form easy-tear lines;

[0018] A method for packaging fruits and vegetables includes the following steps:

[0019] Step 1: Deliver the material to the fulcrum position;

[0020] Step 2: Horizontally clamp and laterally wrap the material;

[0021] Step 3: Horizontally clamp and move the covering material away from the fulcrum;

[0022] Step 4: Vertically and crosswise clamp and wrap the material;

First, the horizontal clamping and covering mechanism clamps the two sides of the fruit and vegetables and covers them horizontally. Then, the clamped fruit and vegetables enter the vertical clamping and covering mechanism, where the vertical clamping and covering mechanism and the horizontal clamping and covering mechanism cross-cover the fruit and vegetables. After the covering is completed, the film covering the outside of the fruit and vegetables is thermoplasticized and shaped by the thermoplastic shaping mechanism to complete the fruit and vegetable packaging.
