Description

Technical Field

[0001] This utility model relates to the field of carton sealing machine technology, and more specifically, to a lifting mechanism for a carton sealing machine. Background Technology

[0002] Paper packaging machines utilize pre-formed cardboard to automatically and continuously package glass bottles, PET bottles, and cans. They are compatible with automated production lines in industries such as beer, beverages, food, and pharmaceuticals, and are especially suitable for secondary carton packaging when integrated with filling lines. The process includes bottle conveying, stacking, cardboard conveying, carton feeding, glue spraying, wrapping, and output.

[0003] Most carton packaging machines on the market are designed for packaging cartons of the same size. The cartons to be packaged are placed into the carton packaging machine, and the tape applicator inside the machine will apply tape to the gaps in the cartons that need to be sealed. Usually, the tape applicator has its own adjustment function to adapt to cartons of different sizes. However, the tape applicator has limited size adaptability. If the height of the cartons varies greatly, the tape applicator will not be able to complete the sealing process for the gaps in the cartons. In view of this, we propose a lifting mechanism for a carton packaging machine. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0058] This embodiment provides a lifting mechanism for a carton sealing machine. Please refer to the attached instruction manual. Figure 5-7 The specific explanation is as follows:

[0059] Please refer to the instruction manual attached. Figure 5 The lifting mechanism includes two or four symmetrically distributed lifting components 900, two of which are symmetrically mounted on the lower support arm 600, as shown in the attached instruction manual. Figure 7 The other two sets of lifting components 900 are symmetrically distributed and installed on the upper support arm 600;

[0060] Continue to refer to the appendix Figure 5 Each lifting assembly 900 includes a fixed connecting rod 910 installed on the housing 100, a lifting slider 920 sleeved on the outside of the fixed connecting rod 910, a cylinder connecting plate 930 connected to the support arm 600, and a lifting cylinder 940. The lifting slider 920 and the cylinder connecting plate 930 are both fixedly installed on the back side of the support arm 600. The lifting slider 920 is slidably connected to the fixed connecting rod 910. The piston rod at the output end of the lifting cylinder 940 is fixedly connected to the cylinder connecting plate 930, and the other end is fixed to the housing 100. The height of the support arm 600 is adjusted by extending and retracting the output end of the lifting cylinder 940 to adjust the height of the upper and lower tape applicators.

[0061] Continue to refer to the instruction manual appendix Figure 6 Further explanation of the cylinder connecting plate 930 in this embodiment: The cylinder connecting plate 930 includes an integrally formed cylinder connecting plate angle steel plate 931 and a cylinder connecting plate connecting plate 932. One end of the cylinder connecting plate angle steel plate 931 is fixedly connected to the support arm 600, and the other end of the cylinder connecting plate angle steel plate 931 is connected to the output piston rod of the lifting cylinder 940. The cylinder connecting plate connecting plate 932 is located on the side of the cylinder connecting plate angle steel plate 931 facing the synchronous transmission gear 1030. The cylinder connecting plate 930 is set in a similar triangular structure to improve the stability when the output piston rod of the lifting cylinder 940 drives the cylinder connecting plate angle steel plate 931 to move.

[0062] This embodiment uses the two sets of lifting components 900 located at the bottom as an example for specific explanation: refer to the appendix of the instruction manual. Figure 5The fixed connecting rod 910 and the lifting cylinder 940 are both installed inside the housing 100. The lifting slider 920 and the cylinder connecting plate 930 are both fixed on the support arm 600. When the lifting cylinder 940 is activated, the piston rod at the output end of the lifting cylinder 940 extends, pushing the cylinder connecting plate 930 upward, which in turn drives the support arm 600 upward. With the cooperation of the fixed connecting rod 910 and the lifting slider 920, the support arm 600 will move vertically upward in the direction of the fixed connecting rod 910, thereby realizing the rise of the side sealing lower tape applicator 800. Similarly, the piston rod at the output end of the lifting cylinder 940 retracts, realizing the fall of the side sealing lower tape applicator 800, thus realizing the rise and fall of the side sealing lower tape applicator 800. The rise and fall of the side sealing upper tape applicator 700 is the same as that of the side sealing lower tape applicator 800, and will not be described in detail here. The positions of the side sealing upper tape applicator 700 and the side sealing lower tape applicator 800 can be adjusted to accommodate cartons of different heights.

[0063] Continue to refer to the instruction manual appendix Figure 5 To further explain the lifting assembly 900 in this embodiment, a synchronization assembly 1000 is provided between the two sets of lifting assemblies 900 to maintain synchronous lifting. The synchronization assembly 1000 includes a horizontally arranged lifting synchronization shaft 1010. A first fixing plate 1020 for mounting bearings is provided on the back side of the support arm 600 near both ends of the lifting synchronization shaft 1010. The first fixing plate 1020 is fixed to the back side of the support arm 600 and moves with the support arm 600. The two ends of the lifting synchronization shaft 1010 pass through the bearings on the first fixing plate 1020 and are then fitted with synchronous transmission gears 1030. A second fixing plate 1040 is fixedly connected to a lifting spur plate 1050 corresponding to the side wall of the synchronous transmission gear 1030. The second fixing plate 1040 is fixed inside the carton packaging machine chassis and is not limited to a specific structure. In this embodiment, the second fixing plate 1040 is installed in the lower synchronization assembly 1000 and is mounted on the lower knife holder assembly 200. The synchronous transmission gear 1030 and the lifting spur plate 1050 mesh and transmit power.

[0064] When the lower support arm 600 moves under the push of the lifting cylinder 940, the movement of the support arm 600 drives the two first fixed plates 1020 to move synchronously, thus synchronously driving the lifting synchronous shaft 1010 to rise. Since a bearing is provided between the lifting synchronous shaft 1010 and the first fixed plate 1020, the two are kept in rotational connection. In addition, the synchronous transmission gears 1030 installed at both ends of the lifting synchronous shaft 1010 mesh with the lifting spur gear plate 1050. When the lifting synchronous shaft 1010 rises along with the support arm 600, the synchronous transmission gears 1030 at both ends rise synchronously along the lifting spur gear plate 1050, thereby avoiding the error in the lifting height of the support arm 600 on both sides caused by the hydraulic push of the lifting cylinders 940 on both sides, so that the two sets of lifting components 900 rise and fall synchronously, further maintaining the stability of the support arm 600 when it rises and falls.

[0065] Example 2

[0066] This embodiment provides a carton sealing machine. Please refer to [link / reference]. Figure 1-12 Specifically, it includes a chassis 100, a support arm 600, a side sealing upper tape applicator 700, a side sealing lower tape applicator 800, a lifting mechanism for adjusting the position of the upper and lower tape applicators, and a side brush swing arm mechanism. For ease of description, the gap when the two top covers of the carton are closed is called the top gap, the gap when the two bottom covers of the carton are closed is called the bottom gap, the gap between the two top covers of the carton and the carton body is called the upper side gap, and the gap between the two bottom covers of the carton and the carton body is called the lower side gap. Therefore, the carton has six gaps: a top gap, a bottom gap, two upper side gaps, and two lower side gaps. When sealing the gaps with tape, half of the tape adheres to the cardboard of the carton, while the other half is suspended. Therefore, a brush is needed to smooth the suspended half of the tape so that the suspended tape adheres to the cardboard of the carton.

[0067] in:

[0068] Inside the chassis 100, a lower blade holder structure and an upper blade holder structure are installed respectively. The cardboard boxes to be packaged are placed between the lower blade holder structure and the upper blade holder structure. The upper and lower blade holder structures are used to seal the top and bottom gaps of the cardboard boxes with tape.

[0069] Specifically: the lower knife holder structure includes a lower knife holder assembly 200 arranged along the carton moving direction and a lower knife holder assembly 300 for carton discharge; the upper knife holder structure includes an upper knife holder assembly 400 located above the lower knife holder assembly 200 and an upper knife holder assembly 500 located above the lower knife holder assembly 300, and is combined with an attached... Figure 3 , 4 As shown in Figure 7, when the packaged items are moved into the machine casing 100 and sealed with tape, the top gap between the left and right top covers of the carton is sealed with tape by the upper knife holder assembly 400. Similarly, the bottom gap between the left and right bottom covers of the carton is sealed with tape by the lower knife holder assembly 200.

[0070] Refer to the instruction manual appendix Figure 4The following is a detailed description of the lower blade holder assembly 200 in this embodiment: The lower blade holder assembly 200 includes a lower roller frame 210, a lower tape applicator 220, a lower brush 230, and two symmetrical first belts 240. The carton moves above the lower roller frame 210. The lower tape applicator 220 is positioned in the middle of the lower roller frame 210 and aligned with the bottom gap of the carton. During the movement of the carton, the bottom gap of the carton is sealed by the lower tape applicator 220 using tape. The lower tape applicator 220 can be any tape applicator in the prior art, which can be easily implemented by those skilled in the art, and will not be elaborated further here. The lower brush 230 is positioned above the lower roller frame 210, aligning with the bottom gap of the carton. The tape applicator 220 is located on one side of the carton's moving direction. During the carton's movement, it contacts the tape sealing the bottom seam of the carton, thus smoothing the tape. Two first belts 240 contact the two sides of the carton respectively to drive the carton to move above the lower roller frame 210. The working process is as follows: Start the drive motor of the first belt 240. The first belt 240 drives the carton from both sides to move above the lower roller frame 210. During the carton's movement, the tape applicator 220 first seals the bottom seam with tape. As the carton continues to move, the lower brush 230 smooths the tape to ensure the quality of the tape sealing.

[0071] Please refer to the instruction manual. Figure 8 The following is a detailed description of the second lower blade holder assembly 300 in this embodiment: The second lower blade holder assembly 300 includes a second lower roller frame 310 and two second belts 320. The two second belts 320 are installed on both sides above the second lower roller frame 310, similar to the first belt 240. When the carton moves above the second lower roller frame 310, the two second belts 320 contact the sides of the carton, thereby driving the carton to continue moving, facilitating unloading. The working process is as follows: When the carton moves from above the first lower roller frame 210 to above the second lower roller frame 310, the second belts 320 clamp the carton from both sides. The drive motor of the second belts 320 is started to drive the second belts 320 to move. The second belts 320 drive the carton forward to complete the sealing process and then unload the carton.

[0072] Please refer to the instruction manual. Figure 7The upper blade holder assembly 400 in this embodiment is described in detail below: The upper blade holder assembly 400 includes an upper blade holder 410, an upper tape applicator 420, and an upper tape applicator brush 430. The upper blade holder 410 is located above the lower roller frame 210, and the upper tape applicator 420 is installed in the middle of the upper blade holder 410. Therefore, the upper tape applicator 420 is located above the lower tape applicator 220. During the movement of the carton, the upper tape applicator 420 seals the top seam of the carton with tape. The tape applicator brush 430 is installed on the side of the upper tape applicator 420 facing the direction of carton movement. During the movement of the carton, it contacts the tape sealing the top gap of the carton and brushes the tape flat. The working process is as follows: When the carton moves above the lower roller frame 210, the upper tape applicator 420 installed in the middle of the upper knife holder 410 applies tape to the top gap of the carton for sealing. As the carton moves continuously, the upper tape applicator brush 430 contacts the tape after sealing the top gap and brushes the tape flat.

[0073] Refer to the instruction manual appendix Figure 3 , 10 11. Two support arms 600 are provided. The two support arms 600 are located at the upper and lower parts of the machine housing 100, respectively. The upper support arm 600 is located on the side of the upper knife holder assembly 400 facing the upper knife holder 500, and a side sealing upper tape applicator 700 is installed on it to seal the upper side seam of the carton. The lower support arm 600 is located on the side of the lower knife holder assembly 200 facing the lower knife holder assembly 300, and a side sealing lower tape applicator 800 is installed on it to seal the lower side seam of the carton.

[0074] Specifically, the support arm 600 is made of aluminum profile, and the side sealing upper tape applicator 700 and the side sealing lower tape applicator 800 are existing technologies, so they will not be described in detail here; among them, the side sealing upper tape applicator 700 and the side sealing lower tape applicator 800 are adjusted in position by a lifting mechanism to facilitate the sealing of cartons of different heights and sizes.

[0075] It is worth mentioning that, in conjunction with the instruction manual... Figure 2 When the front end of the carton moves to the junction of the lower knife holder assembly 200 and the lower knife holder assembly 300, the side sealing upper tape applicator 700 seals the upper side seam of the front end of the carton with tape. Similarly, the side sealing lower tape applicator 800 seals the lower side seam of the front end of the carton with tape. When sealing, the tape length will be slightly longer than the side seam length, and the excess tape length will be adhered to both sides of the carton, forming a horizontal "L" shape on both sides of the side seam. At this time, part of the tape suspended at the side seam is in a horizontal state, and another part is in a vertical state. The specific length is determined by the length of the sealing tape being greater than the side seam length, which can be fully understood by those skilled in the art and will not be elaborated on here.

[0076] After packaging, the side brush swing arm mechanism located on both sides of the carton is used to brush the part of the tape that is vertically suspended flat, so that this part of the tape adheres to the front cardboard of the carton and avoids the tape bulging out.

[0077] Afterwards, the upper side sealing tape applicator 700 and the lower side sealing tape applicator 800 brush the tape flat from the top and bottom sides respectively, so that the part of the tape that is in a horizontal suspended state is attached to the front cardboard of the carton. After brushing the upper and lower side gaps at the front of the carton flat, the carton continues to move to the rear end where it is located at the junction of the lower knife holder assembly 1 200 and the lower knife holder assembly 2 300. The upper side sealing tape applicator 700 and the lower side sealing tape applicator 800 use the same operation to seal the upper and lower side gaps at the rear of the carton with tape, and then use the side sealing large brushes 1300 on both sides and the side brush swing arm mechanism to seal and smooth the upper and lower side gaps at the rear of the carton.

[0078] Please refer to the instruction manual. Figure 9 Two large side sealing brushes 1300 are arranged opposite each other. The upper side sealing brush 1300 is installed above the upper knife holder 2 500 with the brush facing downwards, while the lower side sealing brush 1300 is installed below the lower knife holder assembly 2 300 with the brush facing upwards. The position of both side sealing brushes 1300 is adjusted by a telescopic mechanism to facilitate the sealing of cartons of different sizes. The telescopic mechanism includes telescopic component 1210 and telescopic component 2 1220. Telescopic component 1210 adjusts the lateral extension distance of telescopic component 2 1220, and the height of the side sealing brush 1300 is adjusted by telescopic component 2.

[0079] This embodiment uses the telescopic mechanism installed on the upper side-sealed large brush 1300 as an example for illustration, as follows: The telescopic component one 1210 includes a brush cylinder fixing plate 1211 installed above the upper blade holder two 500, a brush first cylinder 1212 located above the brush cylinder fixing plate 1211, and a brush slider fixing plate 1213. The piston rod at the output end of the brush first cylinder 1212 is connected to the brush slider fixing plate 1213. The brush slider fixing plate 1213 and the brush cylinder fixing plate 1211 are slidably connected. A slider rail structure commonly used in the art can be adopted, which will not be described in detail here. When the brush first cylinder 1212 is activated, its output end piston rod pushes the brush slider fixing plate 1213 to slide above the brush cylinder fixing plate 1211, thereby adjusting the extension distance of the telescopic component two 1220 and realizing the adjustment of the lateral distance.

[0080] Furthermore, the telescopic component 1220 includes a second brush cylinder 1221 and a third brush cylinder 1222 disposed above the brush slider fixing plate 1213. The piston rod at the output end of the second brush cylinder 1221 passes through the brush slider fixing plate 1213 and connects to the third brush cylinder 1222. The output end of the third brush cylinder 1222 is connected to the side sealing large brush 1300. The piston rod at the output end of the second brush cylinder 1221 pushes the third brush cylinder 1222 to adjust its position. This is a longitudinal distance adjustment. Through the dual adjustment of the lateral and longitudinal directions, the adjustment distance of the side sealing large brush 1300 is increased, so that the side sealing large brush 1300 is in different positions, thereby adapting to cartons of different sizes and specifications. In addition, after the position of the side sealing large brush 1300 is adjusted to above the side gap, the output end of the third brush cylinder 1222 extends out, thereby pushing the side sealing large brush 1300 to smooth the tape after sealing the side gap.

[0081] Please refer to the instruction manual. Figure 2 The side brush swing arm mechanism in this embodiment is described as follows: The side brush swing arm mechanism includes a plurality of brush swing arm assemblies 1100. In this embodiment, the number of brush swing arm assemblies 1100 is set to four, which are divided into two groups and installed on the lower blade holder assembly 1 200 and the lower blade holder assembly 2 300 respectively. The two brush swing arm assemblies 1100 in each group are symmetrically distributed.

[0082] Specifically, refer to the instruction manual. Figure 12 The brush arm assembly 1100 includes a vertically arranged spline shaft, a spline shaft slider mounted above the spline shaft, and the position is adjusted by sliding the spline shaft slider on the spline shaft to adapt to different sizes of cartons. A rotatable side sealing first small brush is mounted below the spline shaft slider.

[0083] A second side-sealing brush is installed below the first side-sealing brush. A side-sealing brush cylinder is installed on one side of the second side-sealing brush. The piston rod at the output end of the side-sealing brush cylinder drives the second side-sealing brush to swing. When the second side-sealing brush rotates, it can smooth out the vertical suspended tape at the bottom side seam of the packaged carton, so that the tape adheres to the front cardboard of the carton. At the same time, since both the first and second side-sealing brushes rotate synchronously with the spline shaft, when the first side-sealing brush rotates, it can smooth out the vertical suspended tape at the top side seam of the packaged carton, so that the tape adheres to the front cardboard of the carton. Therefore, the brush swing arm assembly 1100 smooths out the tape at the top and bottom side seams, so that the tape adheres to the carton.
