Description

Technical Field

[0001] The utility model relates to the technical field of side sealing machines, in particular to a simple side sealing machine for cosmetic packaging. Background Art

[0002] After cosmetics are packaged, they usually need to be covered with a film on the outside of the packaging box. The film can protect the outer packaging of cosmetics. When the film is wrapped on the cosmetic packaging, the packaging needs to be put into the film first, and then the packaging film is cut with a hot blade, and the opening is heat-sealed, and then heated and shrunk to make the film fit the outside of the packaging.

[0003] Prior art, such as the patent with publication number CN217673642U, discloses a side-cut film sealing mechanism for a heat shrink packaging machine, which specifically includes a base, a mounting plate symmetrically mounted on the top of the base, a conveyor belt arranged between the mounting plates, a power shaft connected to both ends of the conveyor belt, both ends of the power shaft fixed to the mounting plate through bearings, and one end of the power shaft connected to a first motor, the first motor fixed to the mounting plate through a motor bracket, a U-shaped frame mounting frame mounted on the top of the base, a cylinder mounted on the top of the U-shaped frame, the cylinder passing through the U-shaped frame, a fixed plate mounted on the bottom of the cylinder, a sealing knife fixedly mounted on the bottom of the fixed plate, a heating plate symmetrically mounted on the bottom of the fixed plate, a mounting groove opened on the side of the heating plate close to the sealing knife, and a number of heating blocks evenly fixed in the mounting groove. This application can clean up impurities adhering to the sealing knife through a cleaning roller to avoid affecting subsequent sealing and improve the use effect.

[0004] The existing technology still has shortcomings:

[0005] The sealing mechanism in the above-mentioned prior art lacks a limiting structure for the film when cutting and sealing the film, resulting in that after the heated sealing knife cuts the film, part of the film is easily melted and adhered to the sealing knife due to the heat. After the sealing knife rises, it adheres to the film and pulls the film, causing the articles packaged by the film to be unable to move forward and causing the articles to pile up. Therefore, it is necessary to limit the cutting point of the film to avoid the phenomenon of the sealing knife rising and pulling the film. For this purpose, a simple side sealing machine for cosmetic packaging is proposed. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a simple side sealing machine for cosmetic packaging, which is convenient for laminating the cosmetic packaging.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a simple side sealing machine for cosmetic packaging, comprising a base, a conveyor belt and a bracket are installed on the upper surface of the base, a cylinder is installed on the upper surface of the bracket, the output end of the cylinder passes through the bracket and is installed with a heating sealing knife, and limiting units are installed on both sides of the heating sealing knife. The limiting units include two connecting blocks fixedly connected to the side walls of the heating sealing knife, a sliding sleeve is fixedly connected to the bottom surface of the connecting block, a sliding rod is slidably connected in the sliding sleeve, the upper end of the sliding rod is fixedly connected to a pressure spring, and the other end of the pressure spring is fixedly connected to the inner top wall of the sliding sleeve, and a pressing plate is fixedly connected between the lower end surfaces of the two sliding rods, and the lower end of the pressing plate is lower than the lower end of the heating sealing knife.

[0008] Preferably, the pressing plate is an L-shaped structure, the lower end of the pressing plate close to the heating sealing knife is a sloped structure, the interior of the pressing plate is a hollow structure, and a plurality of first air outlets are provided on the sloped outer wall of the pressing plate, the first air outlets correspond to the sealing positions of the film by the heating sealing knife, the upper surface of the pressing plate is connected to an air inlet pipe, the other end of the air inlet pipe passes through the bracket and is connected to an external air pump, and the penetrating portion of the air inlet pipe and the bracket is fixedly connected to the bracket.

[0009] Preferably, the air intake pipe is located between the bracket and the pressure plate and is a spring-like structure, and the air intake pipe is an elastic pipe.

[0010] Preferably, a plurality of second air vents are provided at the upper end of one side of the pressure plate close to the heating sealing knife, and the second air vents correspond to the outer wall of the lower end of the heating sealing knife. Two scrapers are fixedly connected between the inner walls of the bracket, and the two scrapers are respectively located on both sides of the heating sealing knife. The two scrapers clean the outer wall of the heating sealing knife.

[0011] Preferably, the height of the scraper corresponds to the second air outlet.

[0012] Preferably, the conveyor belt includes a first conveyor belt and a second conveyor belt, a gap is left between the first conveyor belt and the second conveyor belt, the first conveyor belt is located below the heating sealing knife, a slot is opened on the upper surface of the base, the slot is located between the first conveyor belt and the second conveyor belt, and a collection box corresponding to the slot is fixedly connected to the bottom surface of the base.

[0013] Preferably, a cleaning plate is slidably connected inside the collection box, a pull frame is fixedly connected to one side of the cleaning plate, and the length of the pull frame is greater than the length of the inner wall of the collection box.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model installs limiting units on both sides of the heating and sealing knife. When the heating and sealing knife descends to cut and seal the film, the pressure plate in the limiting unit will first contact the film and cooperate with the conveyor belt to clamp the film. Then the heating and sealing knife descends to cut the film. After the film is cut, the heating and sealing knife will rise first, and the pressure plate will still limit the film until the heating and sealing knife rises to a certain height. The pressure plate will rise accordingly. By limiting the film with the pressure plate, the phenomenon that the heating and sealing knife cannot be transported forward due to the adhesion of the film to the film when rising and pulling the film can be avoided, thereby improving practicality.

[0016] 2. The utility model can transport gas to the inside of the pressing plate through an external air pump and an air inlet pipe, and the gas is then discharged from the first air outlet on one side of the pressing plate. Therefore, the gas blown out after the heated sealing knife seals the film can quickly dry the sealed area, so as to avoid the phenomenon that the film at the pulled area is torn again due to the adhesion and pulling of the heated sealing knife when rising, thereby improving practicality.

[0017] 3. In the utility model, the gas in the air intake pressure plate is discharged from the second air outlet, which can dry some film fragments adhering to the outer wall of the heating and sealing knife, and the film fragments dried by the outer wall of the heating and sealing knife can be scraped off by using the scraper located on the inner wall of the bracket, so as to avoid the accumulation of film fragments on the outer wall of the heating and sealing knife to affect the cutting and sealing of the film, thereby improving practicality.

[0018] 4. The utility model uses the first conveyor belt and the second conveyor belt, so that the film fragments scraped off by the outer wall of the heating sealing knife are transported to the junction of the first conveyor belt and the second conveyor belt through the gap between the two and fall into the collection box through the notch for collection, so as to facilitate the centralized treatment of the film fragments.

[0019] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The simple side sealing machine for cosmetic packaging of this embodiment includes a base 1, a conveyor belt 2 and a bracket 3 are installed on the upper surface of the base 1, a cylinder 4 is installed on the upper surface of the bracket 3, the output end of the cylinder 4 passes through the bracket 3 and is installed with a heating and sealing knife 5, and both sides of the heating and sealing knife 5 are installed with a limiting unit 6, the limiting unit 6 includes two connecting blocks 61 fixedly connected to the side wall of the heating and sealing knife 5, the bottom surface of the connecting block 61 is fixedly connected to a sliding sleeve 62, a sliding rod 63 is slidably connected in the sliding sleeve 62, the upper end of the sliding rod 63 is fixedly connected to a pressure spring 64, and the other end of the pressure spring 64 is fixedly connected to the inner top wall of the sliding sleeve 62, and a pressing plate 65 is fixedly connected between the lower end surfaces of the two sliding rods 63, and the lower end of the pressing plate 65 is lower than the lower end of the heating and sealing knife 5.

[0027] like Figure 1-3As shown, the side sealing machine structure in the utility model is similar to the existing side sealing machine structure, such as a side film cutting and sealing mechanism of a heat shrink packaging machine disclosed in the patent with publication number CN217673642U. The main improvement of the utility model is to facilitate the coating of cosmetic packaging; in the utility model, when the cosmetic packaging needs to be coated, the packaging is covered in the film by the conveying mechanism, and the packaging drives the film to move to the conveyor belt 2, and the base 1 supports the conveyor belt 2 and the bracket 3, and moves to the bottom of the heating sealing knife 5 through the conveyor belt 2. The heating sealing knife 5 can be heated, and the heating method can be conduction heating by the heating block. Because the prior art is not shown in the figure, the cylinder 4 is started to work at this time, and the bracket 3 supports the cylinder 4, and the cylinder 4 drives the heating sealing knife 5 to descend. The heating sealing knife 5 drives the sliding sleeve 62, the sliding rod 63 and the pressing plate 65 to descend through the connecting block 61. The pressing plate 65 is located below the heating sealing knife 5, and the pressing plate 65 first contacts with the film The film is then sealed by the cylinder 4 and the cylinder 4 drives the heating and sealing knife 5 to rise, and the heating and sealing knife 5 is separated from the film. Under the elastic force of the pressure spring 64, the pressing plate 65 still presses the film tightly until the heating and sealing knife 5 rises to a certain distance. At this time, the sliding rod 63 and the sliding sleeve 62 are fully extended, and the pressing plate 65 is driven to separate from the film. The restriction of the pressing plate 65 on the film makes the heating and sealing knife 5 rise to seal the film. The adhesion between the film and the heating and sealing knife 5 will be separated due to the restriction of the pressing plate 65 and the upward movement of the heating and sealing knife 5, so as to avoid the adhesion between the heating and sealing knife 5 and the film affecting the transportation of the articles, improve the practicality, and facilitate the production and use.

[0028] like Figure 2 , 3 As shown, the pressing plate 65 is an L-shaped structure, and the lower end of the pressing plate 65 on one side close to the heating and sealing knife 5 is an inclined structure. The interior of the pressing plate 65 is a hollow structure. A plurality of first air vents 8 are provided on the inclined outer wall of the pressing plate 65, and the first air vents 8 correspond to the sealing position of the heating and sealing knife 5 on the film. The upper surface of the pressing plate 65 is connected with an air inlet pipe 7, and the other end of the air inlet pipe 7 penetrates the bracket 3 and is connected with the external air pump. The penetration portion of the air inlet pipe 7 and the bracket 3 is fixedly connected with the bracket 3; after the heating and sealing knife 5 seals the film, the heating and sealing knife 5 stops heating and rises. At this time, the pressing plate 65 still presses down on the film, and the external air pump is started. The external air pump conveys gas into the pressing plate 65 through the air inlet pipe 7, and the gas is blown out along the first air vents 8. The blown wind cools the sealing position of the film, thereby avoiding the phenomenon that the sealing of the film is pulled open when the heating and sealing knife 5 rises due to a certain adhesion between the heating and sealing knife 5 and the film, thereby ensuring the effect of the film on the cosmetic packaging.

[0029] like Figure 2 , 3 As shown, the air inlet pipe 7 is located between the bracket 3 and the pressure plate 65 and is a spring-like structure. The air inlet pipe 7 is an elastic tube. The spring-like air inlet pipe 7 will stretch as the pressure plate 65 descends, and will shrink as the pressure plate 65 rises. The air inlet pipe 7 will not sag and affect the rise and fall of the heating sealing knife 5, thereby improving practicality.

[0030] like Figure 2 , 3 As shown, a plurality of second air vents 9 are provided at the upper end of one side of the pressing plate 65 close to the heating and sealing knife 5, and the second air vents 9 correspond to the outer wall of the lower end of the heating and sealing knife 5. Two scrapers 10 are fixedly connected between the inner walls of the bracket 3, and the two scrapers 10 are respectively located on both sides of the heating and sealing knife 5, and the two scrapers 10 clean the outer wall of the heating and sealing knife 5; when the heating and sealing knife 5 rises, the second air vents 9 also blow out wind to cool the film fragments adhered to the outer wall of the heating and sealing knife 5, and the cooled film fragments are scraped off by the scraper 10 on the inner wall of the bracket 3 as the heating and sealing knife 5 continues to rise, thereby avoiding the phenomenon that the film fragments adhered to the outer wall of the heating and sealing knife 5 affect the cutting and sealing of the film, thereby improving practicality.

[0031] like Figure 2 As shown, the height of the scraper 10 corresponds to the second air outlet 9; after the heating sealing knife 5 rises to its position, the second air outlet 9 corresponds to the scraper 10, and the wind blown out by the second air outlet 9 can blow the film fragments scraped out by the scraper 10 away, avoiding the film fragments from sticking to the scraper 10, thereby improving practicality.

[0032] like Figure 4 As shown, the conveyor belt 2 includes a first conveyor belt 21 and a second conveyor belt 22, a gap is left between the first conveyor belt 21 and the second conveyor belt 22, the first conveyor belt 21 is located below the heating and sealing knife 5, a notch 11 is opened on the upper surface of the base 1, the notch 11 is located between the first conveyor belt 21 and the second conveyor belt 22, and a collecting box 12 corresponding to the notch 11 is fixedly connected to the bottom surface of the base 1; the first conveyor belt 21 conveys the package and the film outside the package to the bottom of the heating and sealing knife 5, and after the film is cut and sealed, the first conveyor belt 21 continues to drive the package to move to the second conveyor belt 22, and the second conveyor belt 22 conveys the package out, and the film fragments scraped off by the scraper 10 first fall on the first conveyor belt 21, and are transported to the gap between the first conveyor belt 21 and the second conveyor belt 22 with the first conveyor belt 21, and the fragments fall from the gap and pass through the notch 11 to fall into the collecting box 12 for collection, so as to facilitate the collection and treatment of the cleaned film debris.

[0033] like Figure 4As shown, a cleaning plate 13 is slidably connected to the collecting box 12, and a pull frame 14 is fixedly connected to one side of the cleaning plate 13, and the length of the pull frame 14 is greater than the inner wall length of the collecting box 12; by pulling the pull frame 14 outward, the cleaning plate 13 can be driven to move in the collecting box 12, and the cleaning plate 13 can take the film fragments collected in the collecting box 12 out of the collecting box 12 for processing, which is convenient and practical.

[0034] The implementation steps in this embodiment are as follows: when the cosmetic package needs to be coated, the package is put into the film by using the conveying mechanism, and the package drives the film to move to the first conveyor belt 21, and the base 1 supports the conveyor belt 2 and the bracket 3, and moves to the bottom of the heating and sealing knife 5 through the first conveyor belt 21. At this time, the cylinder 4 is started to work, and the bracket 3 supports the cylinder 4, and the cylinder 4 drives the heating and sealing knife 5 to descend. The heating and sealing knife 5 drives the sliding sleeve 62, the sliding rod 63 and the pressing plate 65 to descend through the connecting block 61. The pressing plate 65 is located below the heating and sealing knife 5, and the pressing plate 65 is first The heated sealing knife 5 contacts the film, and as the heated sealing knife 5 continues to descend, the heated sealing knife 5 drives the sliding sleeve 62 to slide on the outer wall of the sliding rod 63, and the sliding sleeve 62 drives the pressure spring 64 to be compressed. The elastic force of the pressure spring 64 is used to make the pressing plate 65 cooperate with the conveyor belt 2 to clamp the film until the heated sealing knife 5 contacts the film to cut and seal the film. After the film is sealed, the cylinder 4 drives the heated sealing knife 5 to rise, and the heated sealing knife 5 is separated from the film. Under the elastic force of the pressure spring 64, the pressing plate 65 still presses the film tightly, and the external air pump is started. The external air pump passes through the air inlet pipe 7 transports gas into the pressing plate 65, and the gas is blown out along the first air outlet 8 and the second air outlet 9. The blown air cools the film fragments adhered to the sealing part of the film and the outer wall of the heating sealing knife 5. As the heating sealing knife 5 continues to rise, the scraper 10 on the inner wall of the bracket 3 scrapes off the film fragments cooled by the outer wall of the heating sealing knife 5. After the heating sealing knife 5 rises to its position, the second air outlet 9 corresponds to the scraper 10, and the air blown out of the second air outlet 9 can blow the film fragments scraped by the scraper 10 away, and the sliding rod 63 and the sliding sleeve 62 are fully extended, and the pressing plate 65 is driven to separate from the film. The first conveyor belt 21 continues to drive the package to move to the second conveyor belt 22, and the second conveyor belt 22 conveys the package out. The film fragments scraped off by the scraper 10 first fall on the first conveyor belt 21, and are transported to the gap between the first conveyor belt 21 and the second conveyor belt 22 by the first conveyor belt 21. The fragments fall from the gap and pass through the slot 11 to the collection box 12 for collection. The cleaning plate 13 can be driven to move in the collection box 12 through the external pulling frame 14, and the cleaning plate 13 can take the film fragments collected in the collection box 12 out of the collection box 12.
