Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a servo-driven upward film packaging machine with a transverse sealing structure. Background Art

[0002] A packaging machine is a device that uses packaging bags to package products. For example, during food processing, packaging bags need to be placed on the outside of the food to achieve the purpose of preservation, freshness and convenient transportation. The upper film packaging machine uses packaging film to pass over the top of the product to achieve the packaging purpose. Corresponding to this is the lower film packaging machine.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN218432006U discloses an upper film pillow packaging machine, including: a conveying platform; a packaging module, which is installed on the conveying platform; a conveying module, which is docked with the conveying platform; a bag former, which is located between the packaging module and the conveying module; a ground roller table, which is arranged on the side of the conveying module, and the ground roller table is detachably connected with a roller for carrying a roll film; a reversing frame, which is connected to the ground roller table, and the reversing frame is located above the conveying module, and the ground roller table is provided with a tensioning mechanism between the roller and the reversing frame; a film discharging module, which is provided with an active roller for discharging film, and the reversing frame and the bag former are docked through the film discharging module. Since the roller of the utility model is arranged on the ground roller table, no matter how large the size of the roll film is, the ground roller table can effectively support the two ends of the roller, and the roll film can be easily replaced to adapt to the use of large-sized roll film;

[0004] During use, the above-mentioned device unwinds the roll film so that the roll film covers the outside of the product to achieve the packaging purpose. However, during actual use, the reel in the above-mentioned device can only install one roll at a time, so it needs to be replaced after use to continue working, which makes the replacement process more frequent, increases the workload of personnel and reduces the overall work efficiency. Utility Model Content

[0005] The utility model aims to provide a servo-driven upward film packaging machine with a transverse sealing structure, so as to solve the problem in the above-mentioned background technology that frequent replacement of film rolls reduces the overall work efficiency.

[0006] To achieve the above object, the utility model provides the following technical solution: a servo-driven upward film packaging machine with a transverse sealing structure, comprising a working platform horizontally placed on the ground with lower legs, the upper surface of the working platform is in a groove-shaped structure, and a servo motor is fixedly installed on the front outer surface of the working platform, and also includes:

[0007] A conveyor belt is horizontally rotatably mounted on the inner side above the working platform, and product bodies to be packaged are placed at equal intervals on the upper surface of the conveyor belt;

[0008] Side limiting rollers are rotatably mounted on the front and rear sides of the working platform, and the side limiting rollers are evenly distributed from left to right with equal spacing;

[0009] A mounting plate is longitudinally fixedly mounted on the upper surface of the rear side of the working platform, a power device is arranged inside the mounting plate, and a mounting roller and a guide roller are arranged on the outer surface of the front side of the mounting plate, and a packaging film in a roll structure is sleeved and mounted on the outer side of the mounting roller;

[0010] The edge sealing device is fixedly mounted on the upper surface of the right end of the working platform, and the edge sealing device is in an upwardly arched structure as a whole.

[0011] Preferably, a movable plate with two hole structures is horizontally arranged inside the edge sealing device, and heat sealing strips for horizontally sealing the packaging film are fixedly installed at the left and right ends of the lower surface of the movable plate. After the movable plate moves downward, the heat sealing strips on its lower surface are used to automatically seal the packaging film wrapped around the outside of the product body.

[0012] Preferably, the upper surface of the movable plate is fixedly connected to a telescopic cylinder fixedly installed above the edge sealing device, and a connecting structure is formed between the telescopic cylinder and a small air pump fixedly installed outside the edge sealing device. An infrared sensor for determining the position of the product body is fixedly installed inside the edge sealing device. The infrared sensor is used to detect whether there is a product body passing through the edge sealing device. At this time, the infrared sensor transmits a signal to the small air pump using a wire and turns on the small air pump.

[0013] Preferably, the installation rollers are fixedly connected to the movable frame, and four installation rollers are symmetrically arranged about the center of the movable frame, so that four groups of packaging films can be installed simultaneously by using the installation rollers.

[0014] Preferably, a rotating structure is formed between the movable frame and the mounting plate, and a driven gear is coaxially fixedly installed at the rear of the movable frame, and a driving gear is meshingly connected to the side of the driven gear, and the meshing between the driving gear and the driven gear is utilized to drive the movable frame to rotate, thereby automatically replacing the packaging film for use and reducing the replacement steps.

[0015] Preferably, a cleaning brush is fixedly installed on the inner lower surface of the working platform, and the upper surface of the cleaning brush is pressed and fitted with the outer surface of the conveyor belt.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the servo-driven upward film packaging machine with a transverse sealing structure adopts a new structural design, so that the device can install four groups of packaging films at one time during use, and the four groups of packaging films can work continuously by rotating, reducing the frequency of replacing the packaging films by the staff, improving the overall work efficiency, and after packaging, the heat sealing strip under the movable plate is used to heat-seal the packaging films on the outside of the front and rear products, so that adjacent products are separated. The specific contents are as follows:

[0017] 1. The movable frame, installation roller, driven gear and driving gear are used in coordination. Four installation rollers can be used to install four groups of packaging films at the same time. After one group of packaging films is used up, the installation rollers are driven to rotate through the transmission between the driving gear and the driven gear, and the next group of packaging films is automatically replaced for continued use, so that the staff does not need to frequently disassemble and replace the packaging films, making the overall working continuity of the device stronger, thereby achieving the purpose of improving work efficiency.

[0018] 2. The movable plate, telescopic cylinder, infrared sensor and heat sealing strip are used in coordination. When the infrared sensor detects that a product body is passing below, the telescopic cylinder is activated by a small air pump, thereby driving the movable plate to move downward. Finally, the heat sealing strip under the movable plate is used to automatically seal the packaging films on the outside of the two adjacent product bodies. BRIEF DESCRIPTION OF THE DRAWINGS
