Abstract
Description
Technical Field
[0001] This application relates to the field of drip coffee production, and in particular to a sealing film cutting device. Background Technology
[0002] In the production and packaging process of drip coffee, bag sealing is a key step to ensure product quality and extend shelf life. Its core requirement is to achieve effective sealing of the bag to prevent oxygen and moisture from entering and to slow down the leakage of nitrogen gas filled into the bag. A good sealing effect can lock in the fresh flavor of coffee powder and slow down oxidation and deterioration.
[0003] Currently, the industry typically uses sealing film for packaging, and the mainstream process is heat sealing. The working logic of this process is as follows: first, coffee powder is quantitatively filled into the inner bag, then the inner bag is placed inside the sealing film pre-cut by the cutting device, then a portion of the sealing film is heated to its melting point by a heating device, and then pressure is applied to the sealing film to fuse the material to seal the inner bag, and then it is cooled and shaped to obtain the bag containing the coffee powder inner bag.
[0004] The heating devices, pressing devices, and cutting devices related to the above-mentioned production process are all independently set up and are general-purpose equipment. There is insufficient production coordination between the various devices. Production personnel need to assist in the continuous debugging of each device and the positioning and adjustment of materials. The production efficiency is not high and cannot meet the needs of large-scale continuous production. Utility Model Content
[0005] In order to improve the efficiency of sealing inner bags with sealing film and achieve effective sealing, this application provides a sealing film cutting and sealing device.
[0006] The sealing film cutting and sealing device provided in this application adopts the following technical solution: A sealing film cutting device includes a heat pressing mechanism and a cutting mechanism; The hot pressing mechanism includes a driving component, a hot pressing component, and an elastic pressing component. The hot pressing component and the elastic pressing component are both connected to the driving component. The elastic pressing component includes a pressing block with a through pressing groove. At least a portion of the hot pressing component passes through the pressing groove. The pressing block is configured to move relative to the hot pressing component along the pressing direction so that at least a portion of the hot pressing component moves out of the pressing groove.
[0007] By adopting the above technical solution, the continuous sealing film passes through the pressing block side, and the driving component drives the pressing block to move and press it onto the sealing film to fix the position of the sealing film. At this time, as the driving component continues to work, the hot pressing part can move out of the pressing groove and press onto the sealing film, while simultaneously heating the sealing film to seal the edge. The above actions, combined with the action of inserting the sealing film into the inner bag, can complete the sealing of the inner bag containing coffee powder. Subsequently, the continuous sealing film reaches the cutting mechanism side and is cut by the cutting mechanism to obtain the bag containing the inner bag of coffee powder.
[0008] In one specific implementation, the resilient pressing assembly further includes a pressing spring located between the pressing block and the drive assembly, the pressing spring causing the pressing block to tend to move away from the drive assembly.
[0009] By adopting the above technical solution, when the hot-pressing component is used to heat-press the sealing film, the pressing spring can provide the pressing block with the force to press the sealing film.
[0010] In one specific implementation, the elastic pressing assembly further includes a guide post, one end of which is connected to the driving assembly, and the other end of which is slidably connected to the pressing block, with the pressing spring sleeved on the guide post.
[0011] By adopting the above technical solution, the guide column can guide the movement of the pressing block.
[0012] In one specific implementation, the drive assembly includes a hot-press drive element and a base connected to the hot-press drive element; the base includes an internal heating core plate and a heat insulation plate connected to the heating core plate, and the hot-press element is connected to the heating core plate.
[0013] By adopting the above technical solution, the hot-pressed parts can be heated by heating the heating core plate, and the heat insulation plate can prevent heat from being conducted outward.
[0014] In one specific implementation, the hot pressing component includes a hot pressing horizontal bar and two hot pressing vertical bars, the two hot pressing vertical bars being fixedly connected to the heating core plate, and the base body is also connected to a reciprocating drive component, the hot pressing horizontal bar being connected to the reciprocating drive component.
[0015] By adopting the above technical solution, when the reciprocating drive moves the hot-pressing horizontal bar to be aligned with the two hot-pressing vertical bars, the hot-pressing horizontal bar and the two hot-pressing vertical bars can simultaneously perform three-sided heat sealing on the sealing film. However, when the reciprocating drive moves the hot-pressing horizontal bar closer to the sealing film, the hot-pressing horizontal bar and the hot-pressing vertical bars are not aligned, and the hot-pressing horizontal bar can perform horizontal edge heat sealing on the sealing film alone.
[0016] In one specific implementation, the cutting mechanism includes a cutting drive, a mounting base connected to the cutting drive, a cutter connected to the mounting base, and an elastic pressing component also connected to the mounting base.
[0017] In one specific implementation, the elastic pressure-resistant component includes a mounting block connected to a mounting base, the mounting block having a receiving groove, and the cutter located within the receiving groove; the mounting block is connected to a column, the column being slidably connected to a pressure plate, and a pressure spring is sleeved on the column, with both ends of the pressure spring connected to the mounting block and the pressure plate respectively.
[0018] By adopting the above technical solution, the pressure of the pressure plate by the pressure spring can make the pressure plate press firmly against the sealing film when the cutter cuts the sealing film.
[0019] In one specific implementation, the cutter has a blade portion with a pointed tip.
[0020] By adopting the above technical solution, it is easy to cut the sealing film to obtain the bag body.
[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. In this application, firstly, the continuous sealing film passes one side of the pressing block, and the pressing block is moved and pressed onto the sealing film by the driving component to fix the position of the sealing film. At this time, as the driving component continues to work, part of the hot pressing component can be moved out of the pressing groove and pressed onto the sealing film, while the sealing film is heated at the same time to seal the edge. The above actions, combined with the action of inserting the sealing film into the inner bag, can complete the sealing of the inner bag containing coffee powder. Subsequently, the continuous sealing film reaches the cutting mechanism and is cut by the cutting mechanism to obtain the bag containing the inner bag of coffee powder, realizing the effective sealing of the bag and thus firmly locking in the fresh flavor of the coffee powder. 2. When the reciprocating drive moves the hot pressing horizontal bar to be aligned with the two hot pressing vertical bars, the hot pressing horizontal bar and the two hot pressing vertical bars can simultaneously heat seal the sealing film on three sides. However, when the reciprocating drive moves the hot pressing horizontal bar closer to the sealing film, the hot pressing horizontal bar and the hot pressing vertical bars are not aligned, and the hot pressing horizontal bar can heat seal the sealing film on the horizontal side alone. 3. The pressure of the pressure spring on the pressure plate allows the pressure plate to press firmly against the sealing film when the cutter cuts the sealing film. The presence of the tip makes it easier for the cutter to cut the sealing film to obtain the bag body, thus improving the cutting efficiency. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings.
[0029] This application discloses a sealing film cutting and sealing device. It is used to improve the efficiency of sealing inner bags using sealing film.
[0030] Reference Figure 1 A sealing film cutting device includes a frame 1, on which an adjacent hot pressing mechanism 2 and a cutting mechanism 3 are provided, with the cutting mechanism 3 located downstream of the hot pressing mechanism 2.
[0031] During production, the continuous sealing film passes through the hot pressing mechanism 2 and the cutting mechanism 3 in sequence, thereby completing the sealing of the sealing film and the cutting of the sealing film in sequence.
[0032] Reference Figure 1 and Figure 2 The hot pressing mechanism 2 includes a drive assembly 21, a hot pressing component 22, and an elastic pressing component 23 mounted on the frame 1. Both the hot pressing component 22 and the elastic pressing component 23 are connected to the drive assembly 21, which can drive the hot pressing component 22 and the elastic pressing component 23 to move left and right. In this embodiment, two hot pressing mechanisms 2 are provided, symmetrically arranged, and the sealing film passes between the two hot pressing mechanisms 2 from top to bottom.
[0033] Reference Figure 1 and Figure 2 Specifically, the drive assembly 21 includes a hot-press drive component 211 mounted on the frame 1 and a base 212 connected to the hot-press drive component 211. The hot-press drive component 211 is, for example, a cylinder or a hydraulic cylinder. The base 212 includes an internal heating core plate 2121 and multiple external heat insulation plates 2122. The multiple heat insulation plates 2122 wrap around the heating core plate 2121. The hot-press component 22 is connected to the heating core plate 2121. The hot-press component 22 can be heated by heating the heating core plate 2121. The specific structure of the heating core plate 2121 is existing technology.
[0034] Reference Figure 2 and Figure 3 The elastic pressing assembly 23 includes a pressing block 231 located on the right side of the seat 212. A pressing spring 232 is provided between the pressing block 231 and the seat 212. The two ends of the pressing spring 232 are respectively connected to the pressing block 231 and the seat 212. The pressing spring 232 causes the pressing block 231 to maintain a tendency to move away from the seat 212. In order to guide the movement of the pressing block 231, the elastic pressing assembly 23 also includes a guide post 233. One end of the guide post 233 is connected to the seat 212, and the other end of the guide post 233 is slidably connected to the pressing block 231. The pressing spring 232 is sleeved on the guide post 233. The pressing block 231 has a pressing groove 2311 that extends from left to right. At least a portion of the hot pressing member 22 passes through the pressing groove 2311. The pressing block 231 can move relative to the hot pressing member 22 along the pressing direction so that at least a portion of the hot pressing member 22 moves out of the pressing groove 2311 in a direction away from the seat 212.
[0035] Reference Figure 2 and Figure 3 The hot pressing component 22 has a split structure, including a hot pressing horizontal bar 221 and two hot pressing vertical bars 222. The two hot pressing vertical bars 222 are arranged in parallel and the lower end of each hot pressing vertical bar 222 is in contact with the hot pressing horizontal bar 221. The two hot pressing vertical bars 222 are fixedly connected to the heating core plate 2121. The base 212 is also connected to a reciprocating drive component 24, such as a cylinder or hydraulic cylinder. The hot pressing horizontal bar 221 is connected to the output end of the reciprocating drive component 24. The reciprocating drive component 24 can drive the hot pressing horizontal bar 221 to move left and right. During the movement of the hot pressing horizontal bar 221, the hot pressing horizontal bar 221 is always in contact with the hot pressing vertical bars 222 so that the hot pressing vertical bars 222 can conduct heat to the hot pressing horizontal bar 221.
[0036] Reference Figure 2 and Figure 4 In this embodiment, the two hot-pressing vertical strips 222 mainly seal the two sides of the sealing film, while the hot-pressing horizontal strip 221 mainly seals the horizontal side of the sealing film.
[0037] Reference Figure 2 and Figure 4 The specific actions of continuously sealing the inner bag using the sealing film in this application are as follows: When the sealing film reaches the side of the heat-pressing member 22 from top to bottom, the reciprocating drive member 24 is driven to make the heat-pressing horizontal strip 221 flush with the heat-pressing vertical strip 222. The heat-pressing drive member 211 is driven to move the heat-pressing horizontal strip 221 and the two heat-pressing vertical strips 222 toward the sealing film to perform three-sided heat sealing, that is, sealing the bottom edge and the two sides. Then the inner bag is placed into the sealing film and the inner bag will not fall out. Then the sealing film continues to move downward, and the heat-pressing drive member 211 is driven to move the heat-pressing horizontal strip 221 and the two heat-pressing vertical strips 222 again to perform three-sided heat sealing of the sealing film. At this time, the previous inner bag will be sealed and the next inner bag can be put into the sealing film. Repeating the above actions can complete the continuous sealing of the inner bag containing coffee powder. Subsequently, the sealing film is cut by the cutting mechanism 3 to obtain the bag body. It should be noted that for multiple bags produced using the same sealing film, the sealing of the last bag requires first driving the heat-pressing horizontal strip 221 to move outward and protrude from the heat-pressing vertical strip 222, and then driving the heat-pressing drive component 211 to drive the heat-pressing horizontal strip 221 to contact the sealing film individually.
[0038] Reference Figure 5 and Figure 6 The cutting mechanism 3 includes a cutting drive 31 mounted on the frame 1, a mounting base 32 connected to the cutting drive 31, a cutter 33 connected to the mounting base 32, and an elastic pressing component 34 also connected to the mounting base 32. In this embodiment, for ease of cutting, combined with... Figure 1 There are two cutting mechanisms 3, which are symmetrically arranged and have the same structure. The two cutters 33 can cut the sealing film in an alternating manner.
[0039] After the sealing film containing the inner bag moves down to the side of the cutter 33, the cutting drive 31 drives the cutter 33 to move and cut the sealing film to obtain the bag body. At this time, the elastic pressing group will press the sealing film to prevent the sealing film from moving accidentally. It should be noted that the cutter 33 cuts the sealing film at the connection between adjacent uncut bag bodies, that is, at the horizontal edge sealed by the heat-pressing crossbar 221, specifically at the middle position of the horizontal edge in the vertical direction. The cut horizontal edge seal will be divided into two parts, one part as the bottom edge of one bag body and the other part as the top edge of another bag body.
[0040] Reference Figure 5 and Figure 6The cutting drive component 31 includes, for example, a cylinder or hydraulic cylinder. The elastic pressure assembly 34 includes a mounting block 341 connected to the mounting base 32. The mounting block 341 has a receiving groove 3411 that extends towards the sealing film. The cutter 33 is located within the receiving groove 3411. A column 342 is connected to the mounting block 341. A pressure plate 343 is slidably connected to the column 342. A pressure spring 344 is fitted on the column 342. The two ends of the pressure spring 344 are respectively connected to the mounting block 341 and the pressure plate 343. To facilitate the cutter 33 cutting the sealing film, the cutter 33 has a blade 331 with a tip 332.
[0041] The principle of the sealing film cutting and sealing device in this embodiment is as follows: the sealing film reaches one side of the heat-pressing member 22 from top to bottom, the reciprocating drive member 24 is driven to make the heat-pressing horizontal strip 221 flush with the heat-pressing vertical strip 222, the heat-pressing drive member 211 is driven to move the heat-pressing horizontal strip 221 and the two heat-pressing vertical strips 222 toward the sealing film to perform three-sided heat sealing of the sealing film, that is, sealing the bottom edge and the two sides, and then the inner bag is placed into the sealing film; the sealing film continues to move downward, driving the heat-pressing drive member 211. 1. The heat-pressing horizontal bar 221 and the two heat-pressing vertical bars 222 are driven again to heat-seal the sealing film on three sides. At this time, the previous inner bag will be sealed and the next inner bag can be put into the sealing film. Repeat the above actions to complete the continuous sealing of the inner bag containing coffee powder. Finally, the sealing film containing the inner bag reaches the side of the cutter 33. The cutting drive 31 drives the cutter 33 to move and cut the sealing film to obtain the bag body. At this time, the pressure plate 343 will press the sealing film to prevent the sealing film from moving accidentally.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
