Description

Technical Field

[0001] This invention relates to the field of carton opening equipment, and more particularly to a flexible carton opening device. Background Technology

[0002] With the development of online shopping and short video marketing, products and packaging styles have become popular for a certain period, resulting in temporary bestsellers. This places higher demands on the applicability, rapid changeover, flexible manufacturing, and intelligent control of packaging machinery, becoming a major pain point for the industry. Multi-specification carton opening equipment, compatible with the opening of twelve existing carton sizes, achieves true flexible manufacturing, rapid changeover, and intelligent control.

[0003] Furthermore, existing solutions include equipment that uses robotic arms to open flexible boxes of various sizes, but such equipment is expensive, occupies a large space, and is very difficult to program, making it unsuitable for large-scale use. Summary of the Invention

[0004] To address the aforementioned issues, this invention proposes a flexible box-opening device. This device achieves flexible box opening through multiple mechanisms, and its overall space occupancy is relatively small compared to other box-opening devices. Furthermore, the device uses a simple and easy-to-manufacture structure, which is more cost-effective than complex robotic arms and is not difficult to use. This device is also suitable for large-scale application.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] In some embodiments, a flexible box opening device includes at least a feeding device, a box opening device, a filling device, and a box sealing device. One end of the box opening device is adjacent to the feeding device, the other end of the box opening device is adjacent to the filling device, and the other end of the filling device is adjacent to the box sealing device.

[0007] The unpacking device includes at least a first material line, an unpacking mechanism, a first folding mechanism, and a first adhesive applicator. The unpacking mechanism is located at one end of the first material line, the first folding mechanism is located below the unpacking mechanism, and the first adhesive applicator is located below the first material line. After the material is unpacked by the unpacking mechanism, it is folded and sealed at the bottom by the first folding mechanism and the first adhesive applicator.

[0008] The feeding device, carton opening device, loading device, and sealing device are connected in sequence. Internally, the feeding mechanism retrieves carton materials from the storage device, which then transfers them to the carton opening device for opening. The opened carton materials are placed on a material conveyor belt connected to the loading and sealing devices. The material conveyor belt then sequentially passes the carton materials through the loading and sealing devices, ultimately sealing the carton. The sequential connection of these devices makes more efficient use of space, resulting in a more compact overall system. The carton opening device, using suction cups to hold the carton materials, is adaptable to different carton sizes, and the bottom folding mechanism is also adjustable, allowing the entire system to adapt to various carton sizes.

[0009] In some embodiments, the unpacking mechanism includes a first lifting component, a receiving rotating component, and an auxiliary unpacking component; the lifting component is provided with a first slide; the receiving rotating component is located at the upper end of the first slide, and the auxiliary unpacking component is located at the lower end of the first slide, and the receiving rotating component and the auxiliary unpacking component are arranged opposite to each other after rotation.

[0010] The unpacking mechanism is equipped with a receiving rotating component for receiving box materials. The receiving rotating component picks up the box materials through a suction cup and rotates to open the folded box materials. The lower auxiliary unpacking component folds the bottom of the opened box materials so that they can be sealed with tape when they are sent to the next station. The lifting component is mainly used to move the receiving rotating component up and down.

[0011] In some embodiments, the first lifting assembly further includes a first frame, a first slide rail, a first belt assembly, and a first motor; the first slide rail, the first belt assembly, and the first motor are fixed on the frame, and the first motor is connected to the belt assembly; the first slide block is slidably connected to the first slide rail, and the belt assembly is connected to the drive end of the first slide block and drives the first slide block to move up and down;

[0012] The material receiving and rotating assembly includes: a first suction cup, a first bracket, and a first drive motor; the first drive motor is fixed on a first slide, and the drive end of the first drive motor is connected to the end of the first bracket to drive the first bracket to rotate 90°; the first suction cup is disposed on the first bracket;

[0013] The auxiliary unpacking assembly includes: a second suction cup, a second bracket, and a second drive motor. The second drive motor is mounted on the first slide and located below the first drive motor. The power end of the second drive motor is provided with a first gear, and a second gear meshes next to the first gear to make the second gear rotate. The second bracket is connected to the second bracket, and the second suction cup is mounted on the second bracket.

[0014] When the receiving rotating assembly and the auxiliary unpacking assembly rotate, the first bracket and the second bracket rotate, so that the second suction cup is positioned opposite to the first suction cup.

[0015] The frame of the first lifting assembly is located on one side of the feed device's outlet. The frame has two crossbeams, and a first belt assembly is located on the other side of the crossbeams facing the feed device outlet. The first belt assembly has two fixed pulleys, one upper and one lower, fixed at the upper and lower ends of the frame. The belt moves on these pulleys. One of the fixed pulleys at each end is connected to the power end of a first motor, controlling the belt's up and down movement. The belt moves along the crossbeams near the feed device outlet.

[0016] A first slide rail is provided on one side, and a first frame is connected to the first slide rail. At the same time, the first frame is clamped on a first belt by a clamping block and moves up and down with the first belt.

[0017] A first suction cup is provided on the receiving and rotating assembly of the first frame. The first suction cup is used to adsorb the box material sent out by the feeding device. The first suction cup is arranged on the first bracket. One side of the first bracket is connected to the first drive motor. When the first drive motor is driven, the first bracket rotates 90° axially around the side connected to the first drive motor.

[0018] The auxiliary unpacking component, located below the material receiving rotating assembly, rotates the second bracket, causing the second suction cup above the second bracket to rotate and correspond to the first suction cup. The second bracket is vertically positioned with a second gear at one end, which is directly tangentially positioned near the lifting assembly. Optionally, the second bracket can also be positioned above the second gear, with the center of the second gear fixed to the first frame. The second gear can rotate on the first frame and meshes with a first gear. A second drive motor is fixed below the first gear. When the second drive motor is driven, it drives the first gear to rotate, which in turn drives the second gear to rotate, causing the second bracket to rotate around the axis of the second gear. Ultimately, the suction surface of the second suction cup on the second bracket aligns with the suction surface of the first suction cup rotated by the first motor, allowing the first and second suction cups to respectively adhere to both sides of the box material. To open the box, simply keep the suction cups in contact and rotate the second bracket 90° in the opposite direction.

[0019] In some embodiments, the first folding mechanism includes four folding components and a sliding component, with the four folding components arranged opposite to each other in pairs; each folding component includes a folding motor and a folding connecting rod; the power end of the folding motor is connected to two moving arms of the folding connecting rod, and the upper arm of the folding connecting rod performs a swing arm movement of the connecting rod;

[0021] Two folding components are arranged in a cross shape, with each folding component having a certain space between them in the middle. Below the folding components that are far away from the box mechanism, there is also a sliding component. The sliding component is driven by a third drive motor to move a second belt. A second guide rail is arranged parallel to the belt. One side of the folding component on the sliding component is connected to the second guide rail.

[0022] The folding assembly has two rotatable fulcrums below the folding link. One fulcrum is connected to the power end of the folding motor, and the other end is rotatably fixed to the folding assembly. When the motor drives the folding link, it performs an opening and closing swing arm movement. When the box material is opened, the folding assembly swings its arm to close the bottom of the box material and make the bottom cover of the box closed when the box material is transported onto the guide rail.

[0023] In some embodiments, the unpacking mechanism further includes a pressure plate assembly, which mainly includes a pressure plate, a first support frame, and a first lifting cylinder; the first lifting cylinder is fixed on the first support frame, the pressure plate is disposed at the drive end of the first lifting cylinder, and the pressure plate is located above the first material line.

[0024] The pressure plate mechanism is set on the first support frame of the box opening mechanism. It moves up and down under the action of the first lifting cylinder. The pressure plate presses the box material when it is conveyed from the first material line to the box opening line.

[0025] In some embodiments, the feeding mechanism includes at least one automatic material handling component and at least one storage layer; the storage layer is divided into at least one storage cabinet, and the inner side wall of the storage cabinet is provided with a through groove for the automatic material handling component to pass through;

The side wall of each storage cabinet has a through-slot for the automatic material handling component. The automatic material handling component is located above the storage cabinet, and above it is a track assembly for the automatic material handling mechanism to move. A first moving component is mounted on the track assembly and moves along it. The drive source for the first moving component is located on the track assembly. The motor drive assembly on the first moving component provides power to the robotic arm on the material handling component, allowing the robotic arm to swing up and down within the through-slot. The free end of the robotic arm is connected to a suction cup, which is used to pick up unopened boxes stored in the storage cabinet.

[0032] In some embodiments, the sealing device includes a second material line, a second folding mechanism, a second adhesive applicator, a third adhesive applicator, and a second lifting assembly; the second lifting assembly is disposed on the left and right sides of the second material line, and a second slide is connected to the left and right second support frames, and the second slide is disposed on the second folding mechanism and the second adhesive applicator; the third adhesive applicator is disposed at the tail end of the second material line and is disposed on the second material line, the second adhesive applicator applies adhesive to the top of the box material downwards, and the third adhesive applicator applies adhesive to the bottom of the box material;

[0033] The second slide is located behind the folding mechanism and a second adhesive applicator is also provided. Pressure blocks are provided on both sides of the second adhesive applicator on the second slide. The pressure blocks are sleeved on the guide rod. The lower part of the guide rod is fixed to the second line body, and the upper end is suspended above the second line body.

[0034] The sealing device has second lifting components on the left and right sides of the second material line. A second slide is connected to the second lifting component, and a second folding mechanism is installed on the second slide. The second folding mechanism is mainly used to fold the top of the incoming material after packing.

The second lifting components allow the second slide to accommodate various box sizes. A third adhesive applicator is located at the exit of the sealing device, on the second material line, and applies adhesive to the bottom of the box. On both sides of the second adhesive applicator on the second slide, pressure blocks are fixed. These pressure blocks are fitted onto guide rods, the bottom of which are fixed to the second material line. When the second slide slides up and down, the pressure blocks also move up and down, pressing the top of the box.

[0035] In some embodiments, the second lifting assembly includes: a second frame, a second slide rail, a second belt assembly, and a second motor; the second slide rail, the second belt assembly, and the second motor are fixed on the frame, and the second motor is connected to the belt assembly; a first slide block is slidably connected to the second slide rail, and the second belt assembly is connected to the drive end of the second slide block and drives the second slide block to move up and down.

[0036] The second lifting assembly drives the second slide block clamped on the belt to move up and down through the second belt, the second guide rail, and the second motor set in the left and right frames.

[0037] In some embodiments, the second folding assembly further includes: the second folding mechanism includes: a first swing arm assembly, a second swing arm assembly, a first support arm, a pressing assembly, and guide rods; the first support arm is disposed at the front end of the second slide block, the first support arm is provided with the first swing arm assembly, the fixed end of the first swing arm assembly is connected to the first support arm, the free end of the first swing arm assembly is connected to the second swing arm assembly, the pressing assembly is fixed at the downward extension of the first support arm, and two inclined upward guide rods are also provided below the first support arm, with an included angle of less than 180° between the guide rods.

[0038] The second folding assembly is connected to the second slide block via the first support arm. One end of the first support arm is fixed to the second slide block, and the other end is fixed to the first swing arm assembly. The first swing arm assembly includes a cylinder and a swing arm. One end of the cylinder is connected to the first support arm, and the other end is connected to the middle of the swing arm. When the cylinder pushes, the swing arm opens and swings. At the front end of the swing arm, a second swing arm assembly is provided. The second swing arm assembly includes a cylinder and a swing arm. The cylinder power end of the second swing arm assembly is located in the middle of the swing arm of the second cylinder swing arm assembly. When the cylinder pushes, the swing arm of the second swing arm assembly opens and swings at the free end of the first swing arm assembly. The swing arm of the second cylinder swing arm assembly is shovel-shaped. During folding, the shovel-shaped swing arm better folds the top of the box material. The double swing arm design allows for a larger folding space, making it more adaptable to various box materials of different sizes. A pressing assembly extends from below the first support arm. This assembly consists of a cylinder, a swing arm capable of linkage motion, and a pressing plate. When the cylinder pushes, the linkage swing arm lifts the pressing plate, achieving a swinging folding effect. The pressing plate and the second swing arm assembly then close the top of the box material, achieving the folding effect.

[0039] In some embodiments, the first, second, and third adhesive application mechanisms include: an adhesive application plate, a third swing arm assembly, a fourth swing arm assembly, adhesive tape, a spring, a first connecting arm, a second connecting arm, a toothed blade, and a first connecting rod; the third and fourth swing arm assemblies are rotatably fixed to one side of the adhesive application plate, and the first connecting arm is also connected at the connection point between the third swing arm assembly and the adhesive application plate, and the second connecting arm is also connected at the connection point between the fourth swing arm assembly and the adhesive application plate. One end of the first and second connecting arms is connected, the first connecting rod is horizontally disposed in the adhesive application plate, one end of the spring is disposed on the first connecting rod and the other end is connected to the fourth swing arm assembly, the toothed blade is connected between the third and fourth connecting arm assemblies, and the adhesive surface of the adhesive tape is disposed on the third swing arm assembly.

[0040] As the box material moves, the adhesive tape on the outer surface of the third swing arm assembly contacts and adheres to the box material first. As the box material continues to move, the third swing arm assembly bends. Because there is a connecting rod structure between the two swing arms, the fourth swing arm assembly also bends, causing the spring to deform elastically. The rollers below the third and fourth swing arms also press the tape together. When the third swing arm leaves the box surface, it returns to its original position due to the reset of the spring and connecting rod, at which point the tape has not yet reached the threshold range. When it has moved a certain distance, the toothed cutter can cut the tape, and at this time the third swing arm springs back behind the box, pressing the tape tightly.

[0041] The flexible box opening device of the present invention has the following effects:

[0042] This invention relates to a multi-specification box opening and unpacking device, enabling rapid switching between various box sizes and quick box opening. The storage hopper and material handling device are integrated into a single unit, resulting in a small overall footprint. Furthermore, the device utilizes multiple workstations for box opening, featuring a compact design, flexible workstation arrangement, minimal space requirements, and seamless operation, allowing for rapid loading and unloading and making it suitable for various scenarios.

The second bracket 2432 is connected to the first bracket 2432, and the second suction cup 2431 is mounted on the second bracket 2432. When the receiving rotation assembly 242 and the auxiliary box-opening assembly 243 rotate, the first bracket 2422 and the second bracket 2432 rotate, so that the second suction cup 2431 is positioned opposite to the first suction cup 2421.

[0081] The frame of the first lifting assembly 241 is located on one side of the discharge port of the feeding device 100. The frame has two crossbeams. A first belt assembly is located on the other side of the crossbeams facing the discharge port of the feeding device 100. The first belt assembly has two fixed pulleys, one upper and one lower, fixed at the upper and lower ends of the frame. The belt moves on the fixed pulleys. One of the fixed pulleys at the upper and lower ends is connected to the power end of the first motor 2413, controlling the up and down movement of the belt. The belt moves on the crossbeams facing the discharge port of the feeding device 100.

[0082] A first slide rail 2412 is provided on one side, and a first frame 2411 is connected to the first slide rail 2412. The first frame 2411 is clamped on a first belt by a clamping block and moves up and down with the first belt. A first suction cup 2421 is provided on the receiving and rotating assembly 242 of the first frame 2411. The first suction cup 2421 is used to absorb the box material delivered by the feeding device 100. The first suction cup 2421 is arranged on a first support 2422. A first drive motor 2423 is connected to one side of the first support 2422. When the first drive motor 2423 is driven, the first support 2422 rotates 90° axially around the side connected to the first drive motor 2423.

[0083] The auxiliary unpacking component 243, located below the receiving rotating assembly 242, rotates the second bracket 2432, causing the second suction cup 2431, located above the second bracket 2432, to rotate and correspond to the first suction cup 2421. The second bracket 2432 is vertically positioned with a second gear 2435 at one end. The second gear 2435 is positioned directly as a tangential section near the lifting assembly. Optionally, the second bracket 2432 can also be positioned above the second gear 2435. The center of the second gear 2435 is fixed to the first frame 2411, and the second gear 2435 can rotate on the first frame 2411. A second suction cup 2431 meshes with the first suction cup 2435. A first gear 2434 is provided, and a second drive motor 2433 is fixed below the first gear 2434. When the second drive motor 2433 drives the first gear 2434 to rotate, it causes the second gear 2435 to rotate, which in turn causes the second bracket 2432 to rotate around the axis of the second gear 2435. Ultimately, the suction surface of the second suction cup 2431 on the second bracket 2432 corresponds to the suction surface of the first suction cup 2421 rotated by the first motor 2413. This allows the first suction cup 2421 and the second suction cup 2431 to adsorb the two sides of the box material respectively. When opening the box, it is only necessary to keep the suction cups adsorbed and rotate the second bracket 2432 in the opposite direction by 90° to open the box. In actual implementation, after receiving an unopened box, the box opening device uses the first suction cup 2421 and the second suction cup 2431 to adsorb the box and the second suction cup 2431 to open the box. The box is opened according to the selected specifications through the lifting component. Compared with traditional box opening devices, this device does not require manual adjustment of the box opening mechanism 240 after changing the box material. Moreover, the box opening mechanism 240 is simple to manufacture and the material cost is very cheap.

[0084] In one embodiment of this invention, the first folding mechanism 220 includes four folding components 221 and a sliding component 222. The four folding components 221 are arranged opposite to each other in pairs. Each folding component 221 includes a folding motor 2211 and a folding connecting rod 2212. The power end of the folding motor 2211 is connected to two moving arms of the folding connecting rod 2212, and the upper arm of the folding connecting rod 2212 performs a swing arm movement.

[0085] The sliding component 222 is located away from the box mechanism 240, and the sliding component 222 includes a second guide rail 2221, a second belt assembly 2222, a first movable seat 2223, and a third drive motor 2224. The first movable seat 2223 is slidably connected to the second guide rail 2221, and the second drive motor 2433 drives the first movable seat 2223 to move through the second belt assembly 2222. A folding component 221 is disposed on the first movable seat 2223.

[0086] Two folding components 221 are arranged in a cross shape, with a certain space between each folding component 221 in the middle. Below the folding components 221 located away from the box mechanism 240, a sliding component 222 is also provided. The sliding component 222 is driven by a third drive motor 2224 to move a second belt. A second guide rail 2221 is arranged parallel to the belt. One side of the folding component 221 on the sliding component 222 is connected to the second guide rail 2221. There are two rotatable fulcrums below the folding connecting rod 2212 on the folding component 221. One fulcrum is connected to the power end of the folding motor 2211, and the other end is rotatably fixed to the folding component 221. When driven by the motor, the folding connecting rod 2212 performs an opening and closing swing arm movement. When the box material is opened, the folding component 221 swings its arm to close the bottom of the box material, so that the bottom box cover is closed when the box material is transported onto the guide rail. In actual implementation, the four folding components 221 are arranged in a cross shape below the receiving rotating component 242 and below the first material line 210. The area below the four folding components 221 is raised according to actual conditions, so that when the upper swing arm moves to the top, the four connecting rods of the four folding components 221 are close to the area below the first material line 210 for better folding of the bottom edge of the box material. Below the folding components 221 of the principle box opening mechanism 240, there is a sliding component 222 that allows the folding components 221 to move. In the above embodiment, a bottom rail and belt drive are used to allow the moving folding components 221 to move away from the center of the four folding components 221. The main purpose of the sliding component 222 is to accommodate the folding of various box sizes.

[0087] In one embodiment of this invention, the unpacking mechanism 240 of the present invention further includes a pressure plate assembly 250, which mainly includes a pressure plate 251, a first support frame 252, and a first lifting cylinder 253. The first lifting cylinder 253 is fixed on the first support frame 252, and the pressure plate 251 is disposed at the driving end of the first lifting cylinder 253 and is located above the first material line 210.

[0088] The pressure plate 251 mechanism is mounted on the first support frame 252 of the box opening mechanism 240. A first lifting cylinder 253 causes the pressure plate 251 to move up and down under its action. The pressure plate 251 presses the box material as it is conveyed from the first material line 210 to the box opening line. The pressure plate 251 mechanism is located on the first material line 210. When the opened and folded box is conveyed to the first material line 210, since there is no material inside the box, the pressure plate 251 prevents the box from being too light and vibrating on the first material line 210, thus preventing adhesive application failure.

[0089] Example 4:

[0090] In one embodiment of this example, referring to Figure 11 The sealing device 400 of the present invention includes a second material line 410, a second folding mechanism 420, a second adhesive applicator 430, a third adhesive applicator 440, and a second lifting assembly. The second lifting assembly is disposed on the left and right sides of the second material line 410. Second slides are connected to the left and right second support frames. The second slides are provided with the second folding mechanism 420 and the second adhesive applicator 430. The third adhesive applicator 440 is disposed at the tail end of the second material line 410 and is disposed on the second material line 410. The second adhesive applicator 430 applies adhesive to the top of the box material downwards, and the third adhesive applicator 440 applies adhesive to the bottom of the box material. The second lifting assembly includes a second frame, a second slide rail, a second belt assembly 2222, and a second motor. The second slide rail, the second belt assembly 2222, and the second motor are fixed on the frame, and the second motor is connected to the belt assembly. The first slide is slidably connected to the second slide rail, and the second belt assembly 2222 is connected to the driving end of the second slide and drives the second slide to move up and down.

[0091] The second slide is located behind the folding mechanism and a second adhesive applicator 430 is also provided. On the second slide, pressure blocks are provided on both sides of the second adhesive applicator 430. The pressure blocks are sleeved on the guide rod. The lower part of the guide rod is fixed to the second line body, and the upper end is suspended above the second line body.

[0092] The sealing device 400 has a second lifting assembly on the left and right sides of the second material line 410. The second lifting assembly is connected to a second slide, and the second slide is equipped with a second folding mechanism 420. The second folding mechanism 420 is mainly used to fold the upper part of the incoming material after packing. A second adhesive applicator 430 is also provided behind the second folding mechanism 420. The second adhesive applicator 430 seals the box after folding. The second lifting assembly allows the second slide to adapt to various sizes of box materials. A third adhesive applicator 440 is provided at the outlet of the sealing device 400. The third adhesive applicator 440 is located on the body of the second material line 410 and applies adhesive to the bottom of the box to seal it. On both sides of the second adhesive applicator 430 on the second slide, there are pressure blocks. The pressure blocks are sleeved on the guide rod, and the bottom end of the guide rod is fixed to the body of the second material line 410. When the second slide slides up and down, the pressure blocks also move up and down with the second slide and press the upper part of the box material. The second lifting assembly, via a second belt, a second guide rail 2221, and a second motor located in the left and right frames, drives the second slide, which is clamped on the belt, to move up and down. The sealing device 400 moves up and down according to the size of the box via the lifting assembly, and the second folding mechanism 420 is also equipped with a swing arm to adaptively adjust to different box sizes.

[0093] In one embodiment of this invention, the second folding assembly 221 further includes: a second folding mechanism 420 comprising: a first swing arm assembly 421, a second swing arm assembly 422, a first support arm 423, a pressing assembly 424, and guide rods 425; the first support arm 423 is disposed at the front end of the second slide block, the first swing arm assembly 421 is disposed on the first support arm 423, the fixed end of the first swing arm assembly 421 is connected to the first support arm 423, the free end of the first swing arm assembly 421 is connected to the second swing arm assembly 422, the pressing assembly 424 is fixedly disposed on the downward extension of the first support arm 423, and two inclined upward guide rods 425 are disposed below the first support arm 423, with an included angle of less than 180° between the guide rods 425.

[0094] The second folding assembly 221 is connected to the second slide block via the first support arm 423. One end of the first support arm 423 is fixed to the second slide block, and the other end is fixed to the first swing arm assembly 421. The first swing arm assembly 421 includes a cylinder and a swing arm. One end of the cylinder is connected to the first support arm 423, and the other end is connected to the middle of the swing arm. When the cylinder pushes, the swing arm opens and swings. At the front end of the swing arm, a second swing arm assembly 422 is provided. The second swing arm assembly 422 includes a cylinder and a swing arm. The cylinder power end of the second swing arm assembly 422 is located in the middle of the swing arm of the second cylinder swing arm assembly. When the cylinder pushes, the swing arm of the second swing arm assembly 422 opens and swings at the free end of the first swing arm assembly 421. The swing arm of the second cylinder swing arm assembly is shovel-shaped. During folding, the shovel-shaped swing arm better folds the top of the box material. The double swing arm design allows for a larger folding space, better accommodating various box materials of different sizes. A pressing assembly 424 extends below the first support arm 423. The pressing assembly 424 consists of a cylinder, a swing arm capable of linkage motion, and a pressing plate 251. When the cylinder pushes, the linkage swing arm lifts the pressing plate 251, achieving a swinging folding effect. The pressing plate 251 and the second swing arm assembly 422 close the top of the box material, achieving the folding effect. The second folding assembly 221 combines the two swing arm assemblies with the pressing assembly 424 to fold the upper part of the box body passing through the second material line 410. A second adhesive application assembly then applies adhesive to the upper part and the lower part of the box body.

[0095] Example 5:

[0096] In one embodiment of this example, referring to Figure 12The first adhesive applicator 230, second adhesive applicator 430, and third adhesive applicator 440 of the present invention, as shown, include: an adhesive applicator plate 510, a third swing arm assembly 530, a fourth swing arm assembly 540, adhesive tape 520, a spring 550, a first connecting arm 560, a second connecting arm 570, a toothed blade 580, and a first connecting rod 590; the third swing arm assembly 530 and the fourth swing arm assembly 540 are rotatably fixed to one side of the adhesive applicator plate 510, and the connection point between the third swing arm assembly 530 and the adhesive applicator plate is also connected to... There is a first connecting arm 560, and a second connecting arm 570 is connected at the connection point between the fourth swing arm assembly 540 and the adhesive plate. One end of the first connecting arm 560 and the second connecting arm 570 are connected. The first connecting rod 590 is horizontally arranged in the adhesive plate. One end of the spring 550 is arranged on the first connecting rod 590 and the other end is connected to the fourth swing arm assembly 540. The toothed blade 580 is connected between the third connecting arm assembly and the fourth connecting arm assembly. The adhesive surface of the tape 520 is externally arranged on the third swing arm assembly 530.

[0097] When the box material moves, the adhesive tape 520 on the outside of the third swing arm assembly 530 contacts and adheres to the box material first. As the box material continues to move, the third swing arm assembly 530 bends. Because there is a connecting rod structure between the two swing arms, the fourth swing arm assembly 540 also bends, and the spring 550 also deforms elastically. The rollers below the third swing arm assembly 530 and the rollers below the fourth swing arm also press the adhesive tape 520. When the third swing arm leaves the box surface, it returns to its original position due to the reset of the spring 550 and the connecting rod. At this time, the adhesive tape 520 has not yet reached the threshold range. When it has moved a certain distance, the toothed cutter 580 can cut the adhesive tape 520, and at this time the third swing arm springs back behind the box, pressing the adhesive tape 520 tightly. This adhesive application method mainly uses the inertia of the swing arm assembly to apply adhesive to the box. The process is fully automatic without manual intervention, and this method does not require limitation on the size of the box, and can adapt to the application of adhesive to boxes of different sizes.
