Description

Technical Field

[0001] This utility model relates to the field of automatic packaging technology, and in particular to a folding and sealing device. Background Technology

[0002] A capping and sealing machine is used to package and seal products, making them easier to store and transport.

[0003] In existing technology, the automatic box sealing process requires bending the inner cap first, then bending the outer cap, and finally sealing with glue. The cap-folding and sealing machine includes a lifting mechanism and a cap-folding and sealing mechanism. The lifting mechanisms are located on opposite sides of the product to be sealed, and the opposite sides of the cap-folding and sealing mechanism are slidably connected to the lifting mechanisms. During box sealing, the cap-folding and sealing mechanism slides along the lifting mechanisms to approach the sealing station, where it performs the cap-folding and sealing work. However, when the cap-folding and sealing mechanism is raised to its highest point, its own weight causes the lifting mechanisms on both sides to wobble and loosen, preventing the cap-folding and sealing mechanism from sliding smoothly and affecting the cap-folding and sealing efficiency. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a folding and sealing device that avoids the problem of the folding and sealing mechanism wobbling and loosening during sliding, thus preventing smooth sliding.

[0005] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0006] This utility model provides a folding and sealing device, comprising:

[0007] The lifting mechanism includes two lifting components arranged opposite each other along a first direction, with a working space formed between the two lifting components;

[0008] The cap-folding and sealing mechanism is located within the workspace, and its opposite sides are slidably connected to the two lifting components respectively.

[0009] The lifting assembly includes two lifting structures arranged opposite each other along a second direction. The folding and sealing mechanism has two connecting plates arranged opposite each other along a first direction, with the opposite ends of the connecting plates connected to the two lifting structures respectively. The folding and sealing mechanism extends along the second direction, and the distance between the two lifting structures in the second direction is greater than 50% of the length of the folding and sealing mechanism in the second direction.

[0010] In some implementations, the lifting component includes a lifting drive, the lifting structure includes a slide rail, the connecting plate is provided with a slider, the slider is slidably connected to the slide rail, and the lifting drive drives the connecting plate to slide.

[0011] In this implementation, the two lifting structures are arranged opposite each other along the second direction, so that the two slide rails are arranged opposite each other, thereby reducing the space occupied by the lifting components in the workspace.

[0012] In some implementations, the lifting drive includes a shaft, a motor, a gear, and a timing belt. The motor is driven and connected to the middle section of the shaft. The gear is sleeved on both opposite ends of the shaft. The timing belt is sleeved on the gear and located between two lifting structures arranged opposite each other along a second direction. The connecting plate is connected to the timing belt.

[0013] In this implementation, the motor drives the rotating shaft to rotate, which in turn drives the gear to rotate, thereby driving the synchronous belt transmission. Since the connecting plate is connected to the synchronous belt, the cap-folding and sealing mechanism moves up and down along the slide rail under the drive of the motor, thereby approaching or moving away from the preset position of cap-folding and sealing.

[0014] In some implementations, the cap-folding and sealing mechanism includes a first support rod, a second support rod, a cap-folding assembly, and a sealing assembly. The two ends of the first support rod are respectively connected to the first ends of the two connecting plates, and the two ends of the second support rod are respectively connected to the second ends of the two connecting plates. The cap-folding assembly is connected to the first support rod, and the sealing assembly is connected to the second support rod and located downstream of the cap-folding assembly.

[0015] In some implementations, the sealing assembly is connected to the flap assembly.

[0016] In some implementations, the folding cover assembly includes a folding cover bracket, a front folding cover plate, and a first driving member. The folding covers are connected to the first support rod, the front folding cover plate is rotatably connected to the folding cover bracket, and the first driving member drives the front folding cover plate to rotate relative to the folding cover bracket.

[0017] In some implementations, the folding cover assembly further includes a rear folding cover and a second driving member, the rear folding cover being rotatably connected to the folding cover bracket and located upstream of the front folding cover, and the second driving member driving the rear folding cover to rotate relative to the folding cover bracket.

[0018] In some implementations, the folding cap assembly further includes left and right pressure plates, which are located below the folding cap bracket.

[0019] In this implementation, after the back cover of the carton is folded, the left and right pressure plates bend the left and right tongues of the carton toward the middle of the carton during the continued movement, thereby completing the automatic bending of the front cover, back cover, and left and right tongues of the carton.

[0020] In some implementations, the sealing assembly includes a sealing bracket, a front sealing roller, a cutter, and a rear sealing roller. The sealing bracket is connected to the flap support. The front sealing roller is rotatably connected to the sealing bracket and is wrapped with sealing tape. The rear sealing roller is connected to the cutter via a lever structure. When the carton enters the rear sealing roller, the rear sealing roller is raised, and the cutter is driven down to cut the tape via the lever structure.

[0021] In some implementations, the folding and sealing device further includes a mounting frame and a caster assembly, wherein the lifting mechanism is mounted in the mounting frame and the caster assembly is mounted on the bottom of the mounting frame;

[0022] The mounting bracket has interconnected mounting slots and mounting holes at its bottom. The caster assembly includes a support column and casters. The support column is installed in the mounting slot and has an adjustment hole and a connection hole. A first bolt passes through the adjustment hole to adjust the installation depth of the support column in the mounting slot by rotating the first bolt. A second bolt passes through both the mounting hole and the connection hole to fix the support column in the mounting slot. The casters are rotatably connected to the support column.

[0023] In summary, this utility model has at least the following advantages:

[0024] The folding and sealing device provided by this utility model has a working space formed between two lifting components arranged opposite each other along a first direction. The folding and sealing mechanism is located in the working space and is slidably connected to the two lifting components on opposite sides. The lifting components include two lifting structures arranged opposite each other along a second direction. The two ends of the connecting plate of the folding and sealing mechanism are respectively connected to the two lifting structures. The distance between the two lifting structures in the second direction is greater than 50% of the length of the folding and sealing mechanism in the second direction. The four lifting structures are arranged in parallel to each other, thereby evenly distributing the weight of the folding and sealing mechanism, improving the overall strength of the lifting mechanism, and avoiding the problem of the folding and sealing mechanism shaking and loosening during sliding, thus preventing it from sliding smoothly.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] Please see the appendix Figure 1 ~Appendix Figure 3 The folding and sealing device of this utility model includes a lifting mechanism 10 and a folding and sealing mechanism 20.

[0041] In this regard, please combine Figure 1 and Figure 2 , Figure 1 The diagram illustrates the structural relationship between the lifting mechanism 10 and the folding and sealing mechanism 20 in this embodiment of the present invention. Figure 2 The specific structure of the lifting component 11 in this embodiment of the present invention is illustrated. For ease of description, an example of the first direction and the second direction is defined, specifically as follows: Figure 1 and Figure 2 As shown, the XYZ coordinate axes are defined, where the first direction is parallel to the X-axis and the second direction is parallel to the Y-axis; these two directions are orthogonal to each other. It is understandable that the first and second directions may not be orthogonal.

[0042] Specifically, the lifting mechanism 10 includes two lifting components 11 arranged opposite each other along a first direction, with a working space 12 formed between the two lifting components 11; the cap-folding and sealing mechanism 20 is located within the working space 12, and its opposite sides are slidably connected to the two lifting components 11. The lifting components 11 include two lifting structures 111 arranged opposite each other along a second direction; the cap-folding and sealing mechanism 20 has two connecting plates 21 arranged opposite each other along the first direction, with their opposite ends connected to the two lifting structures 111; the cap-folding and sealing mechanism 20 extends along the second direction, and the distance between the two lifting structures 111 in the second direction is greater than 50% of the length of the cap-folding and sealing mechanism 20 in the second direction.

[0043] In this embodiment, the folding and sealing mechanism 20 is located within the working space 12 formed by the two lifting components 11, and is slidably connected to the two lifting components 11 on opposite sides. This allows the folding and sealing mechanism 20 to move closer to a preset position along the lifting components 11 under the drive of the lifting components 11 when the carton is folded and sealed, thereby folding and sealing the carton. After the folding and sealing work is completed, the lifting components 11 drive the folding and sealing mechanism 20 away from the carton again, thereby realizing fully automatic folding and sealing of the carton.

[0044] Specifically, the lifting assembly 11 includes two lifting structures 111 arranged opposite each other along the second direction. The cap-folding and sealing mechanism 20 extends along the second direction. The two ends of the connecting plate 21 of the cap-folding and sealing mechanism 20 are respectively connected to the two lifting structures 111, that is, the two ends of the two connecting plates 21 are respectively connected to the two lifting structures 111 arranged opposite each other along the second direction, thereby ensuring the balance and stability of the cap-folding and sealing mechanism 20 when it rises and / or falls. The distance between the two lifting structures 111 in the second direction is greater than 50% of the length of the cap-folding and sealing mechanism 20 in the second direction. In this way, the four lifting structures 111 share the weight of the cap-folding and sealing mechanism 20, ensuring the overall strength of the lifting mechanism 10. At the same time, the four lifting structures 111 are parallel to each other, avoiding the cap-folding and sealing mechanism 20 from getting stuck or loose during sliding, which would affect the cap-folding and sealing. Preferably, the distance between the two lifting structures 111 in the second direction is equal to any value between 70% and 80% of the length of the cap-folding and sealing mechanism 20 in the second direction.

[0045] In the aforementioned cap-folding and sealing device, a working space 12 is formed between two lifting components 11 arranged opposite to each other along the first direction. The cap-folding and sealing mechanism 20 is located within the working space 12 and is slidably connected to the two lifting components 11 on its opposite sides. The lifting components 11 include two lifting structures 111 arranged opposite to each other along the second direction. The two ends of the connecting plate 21 of the cap-folding and sealing mechanism 20 are respectively connected to the two lifting structures 111. The distance between the two lifting structures 111 in the second direction is greater than 50% of the length of the cap-folding and sealing mechanism 20 in the second direction. The four lifting structures 111 are arranged parallel to each other, thereby evenly distributing the weight of the cap-folding and sealing mechanism 20, improving the overall strength of the lifting mechanism 10, and avoiding the problem of the cap-folding and sealing mechanism 20 shaking and loosening during sliding, thus preventing it from sliding smoothly.

[0046] In some preferred embodiments, the lifting assembly 11 includes a lifting drive 112, the lifting structure 111 includes a slide rail 1111, and a slider 211 is provided on the connecting plate 21. The slider 211 is slidably connected to the slide rail 1111, and the lifting drive 112 drives the connecting plate 21 to slide. The two lifting structures 111 are arranged opposite to each other along the second direction, so that the two slide rails 1111 are arranged opposite to each other, thereby reducing the space occupied by the lifting assembly 11 in the working space 12, and avoiding the problem of interference between the slide rail 1111 and the slider 211 and the carton when the slider 211 of the folding and sealing mechanism 20 slides along the slide rail 1111, ensuring the flatness of the side wall of the working space 12, and thus making the overall structure more reliable.

[0047] In some more preferred embodiments, please refer to Figure 3 , Figure 3The diagram illustrates the specific structure of the lifting drive component 112 in this embodiment of the present invention. Specifically, the lifting drive component 112 includes a rotating shaft 1121, a motor 1122, a gear 1123, and a synchronous belt 1124. The motor 1122 is driven and connected to the middle section of the rotating shaft 1121. The gear 1123 is sleeved on both opposite ends of the rotating shaft 1121. The synchronous belt 1124 is sleeved on the gear 1123 and located between two lifting structures 111 arranged opposite each other along the second direction. A connecting plate 21 is connected to the synchronous belt 1124. The motor 1122 drives the rotating shaft 1121 to rotate, and the rotation of the rotating shaft 1121 drives the gear 1123 to rotate, thereby driving the synchronous belt 1124 to transmit power. Since the connecting plate 21 is connected to the synchronous belt 1124, the cap-folding and sealing mechanism 20 is driven by the motor 1122 to rise and fall along the slide rail 1111, thereby approaching or moving away from the preset position of cap folding and sealing. It is understandable that because the motor 1122 is connected to the middle section of the rotating shaft 1121, the torque on both ends of the rotating shaft 1121 is evenly distributed. Furthermore, a bearing housing 1125 is also sleeved between the motor 1122 and the gear 1123 on the rotating shaft 1121, which reduces the shear force on the rotating shaft 1121. In this way, while ensuring the stable sliding of the cap-folding and sealing mechanism 20 along the slide rail 1111, the performance of the lifting drive component 112 is improved, and the phenomenon of the rotating shaft 1121 breaking due to uneven torque on both ends of the rotating shaft 1121 is avoided.

[0048] Example 2:

[0049] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the folding and sealing device of this utility model. Please refer to the appendix. Figure 4 .

[0050] The folding and sealing mechanism 20 includes a first support rod 22, a second support rod 23, a folding assembly 24, and a sealing assembly 25. The two ends of the first support rod 22 are respectively connected to the first ends of two connecting plates 21, and the two ends of the second support rod 23 are respectively connected to the second ends of the two connecting plates 21. The folding assembly 24 is connected to the first support rod 22, and the sealing assembly 25 is connected to the second support rod 23 and is located downstream of the folding assembly 24. The folding assembly 24 is used to fold the top cover of the carton, and the sealing assembly 25 is used to seal the folded carton. The first support rod 22 is connected to the first ends of the folding assembly 24 and the two connecting plates 21, and the second support rod 23 is connected to the second ends of the sealing assembly 25 and the two connecting plates 21, thereby allowing the folding assembly 24 and the sealing assembly 25 to be slidably connected to the lifting structure 111. Preferably, the folding cap assembly 24 is connected to the middle section of the first support rod 22, and the sealing assembly 25 is connected to the middle section of the second support rod 23, thereby ensuring the balance of the folding cap assembly 24 and the sealing assembly 25.

[0051] Furthermore, the sealing assembly 25 is connected to the flap assembly 24 to make the overall structure more compact, thereby enhancing the stability of the flap sealing mechanism 20.

[0052] In some preferred embodiments, the folding cover assembly 24 includes a folding cover bracket 241, a front folding cover plate 242, and a first driving member 243. The folding covers are connected to a first support rod 22, the front folding cover plate 242 is rotatably connected to the folding cover bracket 241, and the first driving member 243 drives the front folding cover plate 242 to rotate relative to the folding cover bracket 241.

[0053] In this embodiment, the bottom of the carton to be packaged is sealed, while its front cover, rear cover, and left and right flaps are open. The cover that enters the working space 12 first is the front cover, the cover in the opposite position is the rear cover, and the covers on both sides of the carton are the left and right flaps. That is, the folding and sealing mechanism 20 proceeds from carton feeding to carton discharging.

[0054] During carton sealing, the folding and sealing mechanism 20 slides to a preset position under the drive of the lifting mechanism 10. The carton to be sealed is folded by the front folding cover plate 242 as it moves into the working space 12. The first driving member 243 drives the front folding cover plate 242 to rotate relative to the folding bracket 241, thereby flattening the front cover of the carton. Preferably, the carton to be sealed can enter the working space 12 via a roller conveyor or conveyor belt, and thus be folded by the front folding cover plate 242 during movement.

[0055] In some preferred embodiments, the folding assembly 24 further includes a rear folding cover 244 and a second driving member 245. The rear folding cover 244 is rotatably connected to the folding bracket 241 and is located upstream of the front folding cover 242. The second driving member 245 drives the rear folding cover 244 to rotate relative to the folding bracket 241. After the front cover of the carton to be packaged is folded, the carton continues to move backward. Driven by the second driving member 245, the rear folding cover 244 bends the rear cover of the carton, thereby folding the rear cover of the carton.

[0056] In some more preferred embodiments, the folding assembly 24 further includes left and right pressure plates 246, which are located below the folding bracket 241. After the rear cover of the carton is folded, the left and right pressure plates 246 bend the left and right tongues of the carton toward the middle of the carton during the continued movement, thereby completing the automatic bending of the front cover, rear cover, and left and right tongues of the carton.

[0057] Example 3:

[0058] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the folding and sealing device of this utility model. Please refer to the appendix. Figure 5 ~Appendix Figure 7 .

[0059] In this regard, please combine Figure 5 and Figure 6 , Figure 5 The diagram illustrates the structural relationship between the folding cap assembly 24 and the sealing assembly 25 in this embodiment of the invention. Figure 6 The diagram illustrates the specific structure of the sealing assembly 25 in this embodiment of the present invention. Specifically, the sealing assembly 25 includes a sealing bracket 251, a front sealing roller 252, a cutter 253, and a rear sealing roller 254. The sealing bracket 251 is connected to the flap support 241. The front sealing roller 252 is rotatably connected to the sealing bracket 251 and is wrapped with sealing tape 255. The rear sealing roller 254 is connected to the cutter 253 through a lever structure. When the carton enters the rear sealing roller 254, the rear sealing roller 254 is raised, and the cutter 253 is driven down to cut the tape 255 through the lever structure.

[0060] In this embodiment, in order to seal the carton lid with tape 255 after bending it, a sealing assembly 25 is provided at the rear end of the lid folding assembly 24. A sealing bracket 251 is connected to the lid folding bracket 241. The front sealing roller 252, the cutter 253, and the rear sealing roller 254 are sequentially arranged below the sealing bracket 251. When the carton moves to the front sealing roller 252, the tape 255 is pressed firmly onto the carton by the front sealing roller 252. When the carton moves to the rear sealing roller 254, the rear sealing roller 254 is raised by the carton, which drives the lever structure to move so that the cutter 253 presses down, thereby cutting the tape 255 and completing the sealing of the carton.

[0061] In some preferred embodiments, please refer to Figure 7 , Figure 7 The diagram illustrates the structural relationship between the mounting frame 30 and the caster assembly 40 in this embodiment of the present invention. Specifically, the folding and sealing device further includes a mounting frame 30 and a caster assembly 40. The lifting mechanism 10 is installed in the mounting frame 30, and the caster assembly 40 is installed at the bottom of the mounting frame 30. The bottom of the mounting frame 30 has interconnected mounting grooves 31 and mounting holes 32. The caster assembly 40 includes a support column 41 and a caster 42. The support column 41 is installed in the mounting groove 31 and has an adjustment hole 411 and a connecting hole 412. A first bolt passes through the adjustment hole 411, allowing adjustment of the mounting depth of the support column 41 in the mounting groove 31 by rotating the first bolt. A second bolt passes through both the mounting hole 32 and the connecting hole 412 to fix the support column 41 in the mounting groove 31. The caster 42 is rotatably connected to the support column 41. By rotating the first bolt, the overall height of the folding and sealing device can be adjusted, and then fixed in position by the second bolt. This adjustment method eliminates the need for additional tools or manpower to raise the entire device before adjustment. The height of the entire device can be adjusted simply by rotating the first and second bolts in their original positions, saving manpower and resources.

[0062] The folding and sealing device of this utility model has a working space 12 formed between two lifting components 11 arranged opposite to each other along a first direction. The folding and sealing mechanism 20 is located in the working space 12 and is slidably connected to the two lifting components 11 on opposite sides. The lifting components 11 include two lifting structures 111 arranged opposite to each other along a second direction. The two ends of the connecting plate 21 of the folding and sealing mechanism 20 are respectively connected to the two lifting structures 111. The distance between the two lifting structures 111 in the second direction is greater than 50% of the length of the folding and sealing mechanism 20 in the second direction. The four lifting structures 111 are arranged parallel to each other, thereby evenly distributing the weight of the folding and sealing mechanism 20, improving the overall strength of the lifting mechanism 10, and avoiding the problem of the folding and sealing mechanism 20 shaking and loosening during sliding, thus preventing it from sliding smoothly.
