Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, specifically to a high-efficiency bag making machine for biodegradable packaging bags. Background Technology

[0002] Packaging bags are bags used to package various products. They facilitate the transportation and storage of goods during the production and distribution process and are widely used in daily life and industrial production.

[0003] In current packaging bag making machines, the hot pressing device is used in practice. Due to the different thicknesses of packaging bags of different specifications, the hot pressing temperature varies slightly. Currently, it is mainly controlled by the pre-pressing time. However, thicker plastics require a longer hot pressing time, which prolongs the processing time. At the same time, after the hot pressing plate presses the packaging bag, a small amount of residue will adhere to the outside of the bag. This residue mostly needs to be cleaned manually. However, it is impossible to remove the residue from the machine manually, so workers have to clean it on the machine, which is a very limited process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-efficiency bag-making machine for biodegradable packaging bags, which has the advantages of controllable hot-pressing temperature and easy removal of the hot-pressing plate, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a high-efficiency biodegradable packaging bag making machine, including a mounting frame, a cylinder fixedly mounted on the top of the mounting frame, a fixing frame fixedly mounted on the inner wall of the mounting frame, a heat insulation chamber fixedly mounted on the top of the fixing frame, a protective shell fixedly mounted on the outer wall of the heat insulation chamber, a hot press plate movably connected to the top of the heat insulation chamber, a motor fixedly mounted on the inner wall of the fixing frame, a threaded rod fixedly mounted on the top of the motor, a heating plate slidably connected to the inner wall of the heat insulation chamber, a threaded sleeve and a guide rail fixedly mounted on the bottom of the heating plate, a limit groove formed on the inner wall of the heat insulation chamber, a spring provided on the inner wall of the protective shell, a telescopic plate slidably connected to the inner wall of the protective shell, a pull rod fixedly mounted on the outer wall of the telescopic plate, a fixing block fixedly mounted on the bottom of the hot press plate, and a fixing groove formed on the outer wall of the fixing block.

[0006] As a preferred embodiment of this utility model, the outer wall of the telescopic plate is fitted with the inner wall of the protective shell, and the pull rod penetrates the protective shell.

[0007] As a preferred embodiment of this utility model, the shape of the fixing groove is adapted to the shape of the side of the telescopic plate near the fixing base block, and the height of the telescopic plate and the fixing groove are the same.

[0008] In a preferred embodiment of this invention, the threaded rod extends to the inner wall of the threaded sleeve, and the threaded sleeve is threadedly connected to the threaded rod.

[0009] As a preferred embodiment of this utility model, there are two guide rails and two limiting grooves, and the two guide rails and two limiting grooves are symmetrically arranged on both sides of the inner wall of the heat insulation chamber, and the two limiting grooves are slidably connected to the two guide rails.

[0010] As a preferred technical solution of this utility model, the fixed frame, heat insulation chamber, hot press plate, protective shell, motor, threaded rod, threaded sleeve, heating plate, guide rail and limiting groove are regarded as a movable component, and the two movable components are respectively fixedly assembled with the bottom of the mounting frame and the telescopic end of the cylinder.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This biodegradable packaging bag high-efficiency bag making machine starts the motor, which drives the threaded rod to rotate. The threaded connection between the threaded rod and the threaded sleeve causes the threaded sleeve to move up and down on the outer wall of the threaded rod. This causes the threaded sleeve to pull the heating plate up and down on the inner wall of the heat insulation chamber. This adjusts the distance between the heating plate and the fixed bottom block. The temperature transmission speed is adjusted by adjusting the distance between the heating plate and the fixed bottom block, which in turn adjusts the surface temperature of the hot press plate to suit packaging bags of different thicknesses.

[0013] 2. This high-efficiency biodegradable packaging bag making machine, by pulling the pull rod, causes the pull rod to move the telescopic plate towards the spring, which in turn causes the telescopic plate to retract the spring. At this time, the telescopic plate separates from the inner wall of the fixed groove, thus eliminating the fixing relationship of the fixed groove. At this time, the fixing relationship of the fixed bottom block also disappears. Pulling the hot press plate upward causes the hot press plate to move the fixed bottom block upward, thus removing it from the inner wall of the heat insulation chamber. This makes it easier to clean the surface of the hot press plate. Attached Figure Description

[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 - Figure 5 A high-efficiency biodegradable packaging bag making machine includes a mounting frame 1, a cylinder 2 fixedly mounted on the top of the mounting frame 1, a fixing frame 3 fixedly mounted on the inner wall of the mounting frame 1, a heat insulation chamber 4 fixedly mounted on the top of the fixing frame 3, a protective shell 6 fixedly mounted on the outer wall of the heat insulation chamber 4, a heat pressure plate 5 movably connected to the top of the heat insulation chamber 4, a motor 7 fixedly mounted on the inner wall of the fixing frame 3, a threaded rod 8 fixedly mounted on the top of the motor 7, a heating plate 10 slidably connected to the inner wall of the heat insulation chamber 4, and a threaded sleeve 9 and a guide rail 11 fixedly mounted on the bottom of the heating plate 10. The inner wall of the heat insulation chamber 4 is provided with a limiting groove 12, the inner wall of the protective shell 6 is provided with a spring 13, the inner wall of the protective shell 6 is slidably connected with a telescopic plate 14, the outer wall of the telescopic plate 14 is fixedly installed with a pull rod 15, the bottom of the hot press plate 5 is fixedly installed with a fixed base block 16, and the outer wall of the fixed base block 16 is provided with a fixing groove 17. In the above structure, the heating plate 10 is located below the fixed base block 16. By adjusting the position of the heating plate 10 and the fixed base block 16, the heating rate of the fixed base block 16 is adjusted, thereby regulating the temperature of the fixed base block 16.

[0022] In a preferred embodiment, the outer wall of the telescopic plate 14 is fitted against the inner wall of the protective shell 6, and the pull rod 15 passes through the protective shell 6. In the above structure, the inner wall of the protective shell 6 is fitted against the telescopic plate 14, so that the telescopic plate 14 cannot rotate during movement. Then, by pulling the pull rod 15, the pull rod 15 drives the telescopic plate 14 to move on the inner wall of the protective shell 6, so that the telescopic plate 14 will not tilt during movement.

[0023] In a preferred embodiment, the shape of the fixing groove 17 is adapted to the shape of the side of the telescopic plate 14 near the fixing base block 16, and the height of the telescopic plate 14 and the fixing groove 17 are the same. In the above structure, by inserting the telescopic plate 14 into the inner wall of the fixing groove 17, the height of the fixing groove 17 is fixed, the fixing groove 17 fixes the position of the fixing base block 16, and the fixing base block 16 fixes the position of the hot press plate 5.

[0024] In a preferred embodiment, the threaded rod 8 extends to the inner wall of the threaded sleeve 9, and the threaded sleeve 9 is threadedly connected to the threaded rod 8. In the above structure, by starting the motor 7, the motor 7 drives the threaded rod 8 to rotate, thereby causing the threaded rod 8 to move up and down on the outer wall of the threaded rod 8 through the threaded connection with the threaded sleeve 9, thereby causing the threaded sleeve 9 to move up and down on the top heating plate 10, thereby adjusting the position of the heating plate 10.

[0025] In a preferred embodiment, there are two guide rails 11 and two limiting grooves 12, and the two guide rails 11 and the limiting grooves 12 are symmetrically arranged on both sides of the inner wall of the heat insulation chamber 4. The two limiting grooves 12 are slidably connected to the two guide rails 11. In the above structure, the two guide rails 11 are located inside the two limiting grooves 12, so that the guide rails 11 move on the inner wall of the limiting grooves 12 during the movement of the heating plate 10, so that the guide rails 11 cannot be disengaged from the limiting grooves 12, so that the heating plate 10 is limited during the movement, so that the heating plate 10 cannot tilt or rotate when it moves.

[0026] In a preferred embodiment, the fixed frame 3, the heat insulation chamber 4, the hot press plate 5, the protective shell 6, the motor 7, the threaded rod 8, the threaded sleeve 9, the heating plate 10, the guide rail 11, and the limiting groove 12 are regarded as a movable component, and the two movable components are fixedly assembled to the bottom of the mounting frame 1 and the telescopic end of the cylinder 2, respectively. In the above structure, by activating the cylinder 2, the fixed frame 3 at its telescopic end is moved downward, thereby causing the movable component located at the telescopic end of the cylinder 2 to move closer to the movable component at the bottom of the inner wall of the mounting frame 1.

[0027] Working principle: When using this equipment, the packaging bag arrives above the movable component on the inner wall of the mounting frame 1 via the conveying device. At this point, the two heating plates 10 are activated, generating heat that is then transferred to the interior of the two fixed base blocks 16. The fixed base blocks 16 then transfer the heat to the interior of the hot pressing plate 5, generating heat on the surface of the two hot pressing plates 5. The cylinder 2 is then activated, pushing the movable component at its telescopic end downwards. This causes the upper hot pressing plate 5 to move downwards, bringing it into contact with the top and bottom sides of the packaging bag for a heat-pressing process, thus sealing the bag. When the size of the packaging bag changes, its thickness changes. At this point, the motor 7 is activated, driving the threaded rod 8 to rotate. The threaded rod 8, through its threaded connection with the threaded sleeve 9, drives the threaded sleeve 9 to rotate within the threaded rod. The outer wall of 8 moves up and down, which in turn causes the threaded sleeve 9 to move the top heating plate 10 up and down, thereby adjusting the position of the heating plate 10. At this time, the change in the position of the heating plate 10 causes the distance between the heating plate 10 and the fixed base block 16 to change, resulting in a change in the heat transfer speed to adapt to packaging bags of different thicknesses, so that hot pressing can be completed in the shortest time to adapt to the temperature. When it is necessary to clean the surface of the hot pressing plate 5, the pull rod 15 is pulled, which causes the pull rod 15 to move the telescopic plate 14 towards the inner wall of the protective shell 6, thereby causing the spring 13 to contract. At this time, the telescopic plate 14 is disengaged from the fixed groove 17, thereby eliminating the fixing relationship of the fixed groove 17 and the fixing relationship between the hot pressing plate 5 and the fixed base block 16. At this time, the hot pressing plate 5 is pulled upward, which causes the hot pressing plate 5 to move the fixed base block 16 out from the inner wall of the heat insulation chamber 4, thereby removing the hot pressing plate 5 for easy cleaning of its surface.

[0028] 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.
