Description

Technical Field

[0001] This utility model relates to the field of transparent film packaging machine technology, specifically a cutting assembly for a transparent film packaging machine. Background Technology

[0002] A transparent film packaging machine is a type of equipment used for product packaging. It primarily completes the packaging process through a series of mechanical transmissions and control systems. First, the transparent packaging film is drawn from the film roll. Then, a conveyor belt or other conveying device transports the product to the packaging location. During the packaging process, the film undergoes shaping, wrapping, and sealing. For example, for some three-dimensional products, the film is heated, stretched, and shaped using molds or other devices to conform to the product's shape, then tightly wrapped around the product surface.

[0003] According to patent application number CN202323541948.1, when the outer surface of the silk cake needs to be packaged, the silk cake is first placed on the clamping post on the packaging device. At this time, the transparent packaging film on the packaging film roller is initially wrapped around the silk cake twice. Then, the clamping post is rotated by the No. 2 motor, which drives the silk cake to rotate, so that the transparent packaging film can be wrapped to complete the packaging. This reduces the workload of the workers and improves their efficiency. After the wrapping is completed, the No. 2 hydraulic cylinder on the cutting device drives the cutting blade down into the cutting groove to cut the transparent packaging film, so as to facilitate the workers to package the next silk cake.

[0004] In the aforementioned patent, the transparent film can be cut by moving the cutting blade downward into the cutting groove. However, the cutting groove is recessed and easily accumulates dust particles. When the cutting blade performs frequent cutting operations in the future, it further aggravates the wear at the blade edge and fails to remove the waste material in the cutting groove in time. Therefore, in order to address the above shortcomings and shorten the service life of the cutting blade, this utility model makes the following improvements. Utility Model Content

[0024] 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.

[0025] Example 1

[0026] Please see Figure 1 , Figure 2 as well as Figure 4 and Figure 5 As shown, this utility model provides a technical solution, with specific improvements as follows:

[0027] A cutting assembly for a transparent film packaging machine includes two fixed frames 1 mounted on the packaging machine. Each fixed frame 1 has a column 2 mounted on its top surface. A cutting seat 3 is fixedly mounted between opposite sides of the two columns 2. A cutting groove is formed on the top surface of the cutting seat 3. A scraping plate 4 is slidably mounted inside the cutting groove. A squeezing rod 18 is fixedly mounted on the front side of the scraping plate 4. A driving component for controlling the back-and-forth movement of the scraping plate 4 is mounted on the back side of one of the columns 2. The driving component includes a motor 6. The motor 6 is fixedly connected to the surface of one of the columns 2 via a support rod. A threaded sleeve 7 is rotatably mounted on the back side of one of the columns 2 via a support cylinder. A threaded rod 8 is threadedly connected inside the threaded sleeve, and one end of the threaded rod 8 is connected to the back side of the scraping plate 4. A first gear 9 is fixedly mounted on the output end of the motor 6 via a coupling. A second gear 10 meshing with the first gear 9 is fixedly mounted on the surface of the threaded sleeve 7.

[0028] Another column 2 has a material collection mechanism 5 for collecting waste on its front side. The material collection mechanism 5 includes a collection frame 56, and a collection box 51 is movably installed inside the collection frame 56. A through groove is opened on the top surface of the collection frame 56, and a telescopic curtain 52 is installed inside the through groove. The telescopic curtain 52 can be extended and retracted. Baffles 53 are fixedly installed on both sides of the top surface of the collection frame 56. A sliding groove adapted to the slider is opened on the opposite side of the two baffles 53, and a buffer spring 55 is fixedly connected to the inner wall of the sliding groove and the surface of the slider. A sealing plate 54 is fixedly installed on one side of the telescopic curtain 52, and both sides of the sealing plate 54 are slidably connected to the surface of the baffle 53 through the slider.

[0029] Start the motor 6, which drives the threaded sleeve 7 to rotate through the first gear 9 and the second gear 10. Then the threaded rod 8 inside the threaded sleeve 7 drives the scraper 4 to move forward along the inside of the cutting groove, which can push out the waste material inside the cutting groove.

[0030] When the squeezing rod 18 on the front of the scraper 4 contacts the sealing plate 54, the scraper 4 is controlled to move forward until the sealing plate 54 is pushed open. At this time, the waste material enters the collection box 51 through the through groove. After cleaning, the scraper 4 is controlled to move to the initial position, and the sealing plate 54 moves to the initial position under the action of the buffer spring 55. The through groove is closed by the setting of the telescopic curtain 52 to prevent the waste material inside the collection box 51 from re-entering the cutting groove due to air flow, thus avoiding the inconvenience of secondary cleaning.

[0031] Example 2

[0032] Based on Example 1, please refer to Figure 1 and Figure 3 As shown, the specific improvements are as follows:

[0033] A lifting rod 11 is slidably arranged between the two opposing sides of the two columns 2, and a mounting frame 12 is fixedly arranged on the bottom surface of the lifting rod 11. A blade 13 is arranged inside the mounting frame 12, and a slot adapted to the T-shaped insert plate 15 is opened inside the blade 13. A T-shaped insert plate 15 is movably arranged on one side of the mounting frame 12 through a guide rod 14. A stop is provided at one end of the guide rod 14, and a clamping spring 16 is arranged between the stop and the opposite side of the T-shaped insert plate 15 and on the surface of the guide rod 14. An electric push rod 17 is fixedly arranged at the top of each of the two columns 2 through a mounting plate, and the extended end of the electric push rod 17 is fixedly connected to the top surface of the lifting rod 11.

[0034] Activate the electric push rod 17, causing its extended end to lower the lifting rod 11. The blade 13 then lowers synchronously, allowing for the cutting of the transparent film. When the blade 13 becomes worn and needs replacement, the operator slides the T-shaped insert 15 to the right along the surface of the guide rod 14, causing the T-shaped insert 15 to disengage from the slot. After replacing the blade 13, release the T-shaped insert 15. At this point, the T-shaped insert 15 is reinserted into the slot under the action of the clamping spring 16, thus securing the blade 13.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] 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.
