Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a fully automatic continuous stretch film packaging machine. Background Technology

[0002] The principle of a stretch film packaging machine is as follows: a groove is stretched into the bottom film at the forming station; then, the product is used to fill the groove in the filling section; and finally, the groove is sealed with an upper film at the sealing station. Chinese utility model patent application number 201921649873.X for a stretch film packaging machine includes: a frame for mounting the stretch film packaging machine on a mounting surface; a forming station for stretching the groove into the bottom film; a filling section for filling the groove with the product; and a sealing station for sealing the groove with an upper film extracted from the upper film receiving section.

[0003] In terms of existing technology, the filling section of existing packaging machines mainly relies on manual feeding, which requires people to place the products to be packaged one by one into different grooves of the bottom film. This requires personnel to bend over frequently during filling, especially for filling grooves that are located far away, which is even more difficult.

[0004] In view of this, the purpose of this utility model is to propose a fully automatic continuous stretch film packaging machine with an auxiliary feeding mechanism to solve the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model discloses a fully automatic continuous stretch film packaging machine, including a packaging machine body 1. The packaging machine body 1 is provided with a filling section 3 for loading products into the groove of the bottom film 2. The above is the prior art, which will not be described in detail here. For details, please refer to the Chinese utility model patent for stretch film packaging machine with application number 201921649873.X.

[0022] The filling section 3 of the existing packaging machine mainly relies on manual feeding, which means that the products to be packaged need to be placed one by one into different grooves of the bottom film 2. This requires the personnel to bend over frequently during the filling process, especially for filling grooves that are located far away, which is even more difficult.

[0023] To solve the above problems, the main innovation of this utility model is that the filling section 3 is provided with an auxiliary feeding mechanism 4.

[0024] The auxiliary feeding mechanism 4 includes a mounting plate 41, which is fixed to the filling section 3 of the main body 1 of the packaging machine. A circular guide rail 42 is fixedly provided on the surface of the mounting plate 41. The circular guide rail 42 is existing technology. A feeding hopper 43 is movably mounted on the circular guide rail 42. Driven by the circular guide rail 42, the feeding hopper 43 moves in a circular motion on the surface of the mounting plate 41. A first gate mechanism 44 is provided at the bottom of the feeding hopper 43. When the product is put into the feeding hopper 43, the first gate mechanism 44 can close the bottom of the feeding hopper 43, so that the feeding hopper 43 can carry the product and move.

[0025] With the above structure, when filling products, personnel can stand on the side of the filling section 3 of the main body 1 of the packaging machine and put the products to be packaged into the feeding hopper 43. The feeding hopper 43 moves under the drive of the circular guide rail 42. When it moves to the groove above the bottom film 2 before the product is loaded, the first gate mechanism 44 opens, allowing the product to fall into the groove. Then, the bottom film 2 carrying the product in the groove continues to move. After the subsequent film covering and film cutting processes, a single packaged product is formed. The film covering and film cutting processes are the existing packaging machine structure and will not be described in detail here.

[0026] In some embodiments, a receiving hopper 5 is fixedly disposed above the groove of the bottom film 2 on the mounting plate 41. The bottom of the receiving hopper 5 is provided with a second gate mechanism 51. The receiving hopper 5 is used to temporarily receive the products put into the feeding hopper 43. It can be understood that the grooves are arranged in rows on the surface of the bottom film 2. Therefore, when a row of grooves is filled with products, the bottom film 2 will move forward one row. During the movement, the products put into the feeding hopper 43 will be temporarily stored in the receiving hopper 5. In this way, when the next row of grooves reaches below the receiving hopper 5, the second gate mechanism 51 will open, allowing the products to fall into the grooves.

[0027] To facilitate the detection of whether the groove below the receiving hopper 5 contains products, the receiving hopper 5 is equipped with an infrared sensor 6 for detecting products in the groove of the bottom film 2. When the infrared sensor 6 detects that the groove contains products, the second gate mechanism 51 will not open.

[0028] In some embodiments, the second gate mechanism 51 includes a second gate plate 510 horizontally movably disposed below the receiving hopper 5 and a telescopic cylinder 511 connected between the second gate plate 510 and the receiving hopper 5.

[0029] In order for the baffle to detect whether there is a product in the receiving hopper 5, the second gate 510 is equipped with a first pressure sensor 7. When there is a product in the receiving hopper 5, the first pressure sensor 7 can sense the pressure, so that the feeding hopper 43 will not put the product into the receiving hopper 5 when it passes by, but will directly pass by the receiving hopper 5. Conversely, when the first pressure sensor 7 does not detect the pressure, it means that the receiving hopper 5 is empty, and the feeding hopper 43 will put the product into the receiving hopper 5 when it passes by.

[0030] In some embodiments, the first gate mechanism 44 includes a first gate plate 440 rotatably mounted on the bottom of the feeding hopper 43 and a motor 441 fixed on the feeding hopper 43 for driving the first gate plate 440 to rotate.

[0031] To prevent repeated product loading into the feeding hopper 43, a second pressure sensor 8 is installed on the surface of the first gate 440. The second pressure sensor 8 is used to detect whether there is product on the surface of the first gate 440. The feeding hopper 43 is equipped with an LED light 9. When the first gate 440 detects a product through the second pressure sensor 8, it sends a signal to the microcontroller. The microcontroller can be fixed on the feeding hopper 43. The output terminal of the microcontroller is connected to the input terminal of the LED light 9 to control the LED light 9 to turn on, so that personnel will not repeatedly put products into the feeding hopper 43. In this way, personnel only need to put the product into the feeding hopper 43 where the LED light 9 is not lit. The rest of the filling can be done automatically, making the entire packaging work orderly and more labor-saving.

[0032] In summary, this utility model aims to solve the problems of low efficiency and difficult operation caused by manual feeding in the prior art. The auxiliary feeding mechanism 4 can automatically place the product into the groove of the bottom film 2, thereby reducing the frequency and difficulty of manual operation and improving the overall working efficiency of the packaging machine.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
