Description

Technical Field

[0001] The invention relates to the technical field of corrugated box sealing, in particular to a fully automatic plastic corrugated box sealing device using an adhesive tape. Background Art

[0002] Plastic corrugated boxes are common objects for packaging products. They are folded into a box to hold the product. After closing the corrugated box, it is usually necessary to seal it with tape to strengthen the corrugated box and protect the product.

[0003] Defect 1: Although it solves the problem of manual packaging and low efficiency, it does not solve the problem of the lifting stability of the device during packaging. At the same time, it cannot limit the packaging box, which easily causes the device to deviate during packaging;

[0004] In order to solve the above-mentioned defect 1, the prior art 1 (application number 202121831671.4, Chinese patent with application date of 2021-08-06) discloses a tape box sealing machine with adjustable size. The tape box sealing machine with adjustable size can enhance the stability of the packaging mechanism body during lifting and lowering through the joint action of the recessed frame, lifting assembly, slide groove and slider, prevent the box from deviation during packaging, resulting in incomplete packaging. Through the setting of the first electric push rod and the limit plate, it can be adjusted according to the size of the box, thereby limiting the box and assisting in positioning the box. Through the joint action of the vertical plate, the motor, the threaded rod and the threaded cap, the packaging mechanism body can be lifted and lowered conveniently, thereby facilitating the packaging of the box. Through the setting of the transmission mechanism body, the packaging of the box can be carried out continuously. Through the setting of the guide plate, the receiving plate, the connecting plate, the pressure rod, the second electric push rod, the L-shaped rod, the fixing rod and the third electric push rod, the box can be folded, thereby reducing manual labor and improving the working efficiency of the device.

[0005] Defect 2: Most of the existing packaging box sealing machines are not equipped with reinforcement devices, so that after the packaging box is sealed by the sealing machine, the tape of some packaging boxes will fall off from the packaging box because it is not firmly adhered, causing the packaging box to be opened during transportation, causing the items in the packaging box to fall out. A small number of packaging box sealing machines are equipped with reinforcement devices, but they cannot fix the position of the packaging box, so that the reinforcement device cannot accurately reinforce the tape, reducing the practicality of the sealing machine;

[0006] In order to solve the above-mentioned defect 2, the second prior art (application number 202121132923.4, Chinese patent with application date of 2021-05-25) discloses an automatic box sealing machine. By setting a support plate, a top plate, an electric telescopic rod, a connecting plate, a sliding rod, a sleeve, a sleeve rod, a pressure plate, and a spring A, the function of reinforcing the tape on the box is achieved to prevent the box from opening during transportation and prevent the items in the box from falling out. By setting a pull rod, a splint and a spring B, the function of fixing the position of the box is achieved, so that the reinforcement device can accurately reinforce the tape, thereby improving the practicality of the box sealing machine. By setting a card slot, an adapter slot, a card block, a mounting plate, a limit rod, and a tension spring, the function of installing a conveyor is achieved, which simplifies the traditional installation method of the conveyor, saves the time and energy wasted by workers in disassembling and assembling the conveyor, speeds up the installation rate of the conveyor, and improves the work efficiency of workers;

[0007] At present, corrugated box sealing with tape is usually done manually. The tape is cut to a fixed length by an automatic tape cutter, and the tape is taken out manually from the tape cutter and pasted on the two sides and bottom of the corrugated box in sequence. However, the tape needs to be pasted in the designated positions in sequence, resulting in inconsistent pasting positions and intervals each time, as well as inconsistent tightness of the tape, which makes the tape easy to fall off.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the fully automatic plastic corrugated box tape sealing device adopts a new structural design, and its specific contents are as follows:

[0024] (1) The plastic corrugated box is lifted to the tape-sticking position by means of a lifting cylinder and a placing plate. At this time, a set of one-way wheels are driven by a two-way threaded rod to move horizontally to a position close to the left and right sides and one side of the hinge of the plastic corrugated box according to the size of the plastic corrugated box set by the program, and then the first cylinder is used to make it move vertically upward to start taping from both sides until a set of one-way wheels reaches the top of the corrugated box, and finally moves horizontally to tape the top.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 9 , the present invention provides the following technical solutions: a fully automatic plastic corrugated box tape sealing device;

[0041] Embodiment 1: In order to solve the problem that the current corrugated box tape sealing is usually done manually in the prior art, the tape is cut to a fixed length by an automatic tape cutter, and the tape is taken out from the tape cutter manually and sequentially pasted on the two sides and the bottom of the corrugated box. However, the tape needs to be pasted at the designated positions manually, resulting in inconsistent pasting positions and intervals each time, and inconsistent tightness of the tape, which causes the tape to fall off easily. Therefore, the following solution is disclosed, and specific reference is made to Figure 1-Figure 4 and Figure 6 and Figure 7 As shown, it includes a control console 1, a roller conveyor line 2 is installed on the upper surface of the control console 1, a gantry 3 is fixedly connected to the left and right sides of the upper surface of the control console 1, and a motor is installed above the left side of the gantry 3;

[0042] A lifting cylinder 6 is installed in the middle position inside the console 1, and a placing plate 7 is fixed on the top of the lifting cylinder 6. A two-way threaded rod 4, a screw rod 28 and a limit rod are respectively connected above the two gantries 3; the outer sides of the two-way threaded rod 4, the screw rod 28 and the limit rod are all sleeved with a frame 5, and the lower part of the frame 5 is respectively fixedly connected with a fixed rod 12 and a first cylinder 13, the front end of the screw rod 28 and the outer sides of the two ends of the two-way threaded rod 4 are connected through a bevel gear set, and the threads on the outer sides of the two ends of the two-way threaded rod 4 are in opposite directions. Multiple frames 5 are threadedly connected to the two-way threaded rod 4 and the screw rod 28, and multiple frames 5 are slidably connected to the limit rod, a movable plate 14 is sleeved on the outer side of the fixed rod 12, and a movable plate 15 is connected to one side of the movable plate 14; the side of the movable plate 15 away from the movable plate 14 is connected to a rotating plate 20 through an axis rotation, and a one-way wheel 19 is provided on one side of the rotating plate 20. A second return spring 17 is installed between the left side and the inner wall of the movable plate 14, and the left side inside the movable plate 14 is connected to a driven gear 16 through an axis rotation, and the driven gear 16 and the movable plate 15 are connected through a second traction rope 18. A first tooth block is fixed at equal intervals on the right side of the upper end of the fixed rod 12, and the driven gear 16 and the multiple first tooth blocks on the fixed rod 12 are meshingly connected. One end of the second traction rope 18 is fixed to the side of the movable plate 15, and the other end of the second traction rope 18 is wound around the shaft end of the driven gear 16. The movable plate 15 and the movable plate 14 are slidably connected, and the one-way wheel 19 is a one-way rotating structure composed of a ratchet assembly. A second rack 30 is fixedly connected to one side of the movable plate 14 above the movable plate 15, and a large gear 29 is connected to the inside of the movable plate 15 through an axis rotation, and a small gear 31 is fixedly mounted on the shaft end of the rotating plate 20, and the large gear 29 is meshingly connected to the second rack 30 and the small gear 31;

[0043] After the folding, the corrugated box is automatically transferred to the placement plate 7 along the edge of the roller conveyor line 2. At this time, the first suction cup 8 works to fix the corrugated box, and then the lifting cylinder 6 is started to lift the corrugated box on the placement plate 7 to the tape sticking position, and then the motor is started. The motor drives the bidirectional threaded rod 4 to rotate, and at the same time, the bidirectional threaded rod 4 drives the screw rod 28 to rotate using the bevel gear set. At this time, the two racks 5 located on the bidirectional threaded rod 4 move relatively, and at the same time, the two racks 5 located between the screw rod 28 and the limit rod move forward, so that the corrugated box size set by the program can be adjusted. The one-way wheel 19 is positioned so that it is close to the surface of the corrugated box, and then the two groups of first cylinders 13 are started, one group of first cylinders 13 drives the movable plate 14 to move upward, and the other group of first cylinders 13 drives the movable plate 14 to move downward. At this time, the driven gear 16 is rotated by using a plurality of first gear blocks, and the second traction rope 18 is loosened, so that the second traction rope 18 no longer pulls the movable plate 15. Then the movable plate 14 drives a group of one-way wheels 19 to move vertically upward to start taping from both sides, and then when the one-way wheels 19 reach the top position of the corrugated box, the second return spring 17 is used to return the movable plate 15 to the top of the corrugated box. The elastic force of the one-way wheel 19 pushes the moving plate 15, the rotating plate 20 and the one-way wheel 19 to move, and the second rack 30 is used to rotate the large gear 29 and drive the meshing small gear 31 to rotate, so that the one-way wheel 19 rotates downward by 90 degrees, so that it is arranged perpendicular to the top of the corrugated box, and at the same time, it can move horizontally to stick the top tape, and another set of one-way wheels 19 moves vertically downward to start sticking the tape until the one-way wheels 19 reach the bottom of the corrugated box, and finally moves horizontally to stick the bottom tape, and then the tape is automatically cut after the action is completed, and a set of one-way wheels 19 is driven by multiple first cylinders 13 to stick the tape to the top of the corrugated box. The movable plate 14 moves downward, driving another set of movable plates 14 to move upward at the same time, and under the action of the second tooth block, the driven gear 16 rotates in the opposite direction, reels the second traction rope 18, and then pulls the movable plate 15, the rotating plate 20 and the one-way wheel 19 to reset (the second reset spring 17 is in a compressed state at this time), and then the lifting cylinder 6 drives the placement plate 7 to reset. At this time, the first suction cup 8 is released, completing the automatic tape sealing action of the corrugated box, so that the device has an adaptive function and can adapt to corrugated boxes of different sizes, while ensuring that the tape length and spacing are consistent.

[0044] Embodiment 2: Different from Embodiment 1, this embodiment uses the first suction cup 8 to absorb and fix the corrugated box on the placement plate 7, which can prevent the corrugated box from shifting when the tape is applied and affecting the product quality. For details, refer to Figure 1 , Figure 4 and Figure 8As shown, first suction cups 8 are embedded and installed at equal intervals around the upper surface of the placement plate 7, and the first piston block 11 is sealed and slidably connected inside the first suction cup 8, a first return spring 10 is installed between the bottom of the first piston block 11 and the inner wall of the first suction cup 8, and a first traction rope 9 is fixedly connected between the bottom of the first piston block 11 and the top of the console 1;

[0045] When the lifting cylinder 6 drives the placement plate 7 to rise, the first traction rope 9 can be used to pull the first piston block 11 downward in the first suction cup 8, so that the first suction cup 8 generates negative pressure and adsorbs and fixes the corrugated box on the placement plate 7, thereby preventing the corrugated box from being displaced during tape application and affecting product quality. Then, when the lifting cylinder 6 drives the placement plate 7 to descend, the first traction rope 9 no longer pulls the first piston block 11, so that the first piston block 11 is reset under the elastic force of the first reset spring 10, so that the first suction cup 8 is released and no longer adsorbs and fixes the corrugated box, and then the corrugated box is transported through the roller conveyor line 2.

[0046] Embodiment 3: Different from Embodiment 2, this embodiment uses the cutting blade 26 to move, which can automatically cut the tape, and uses the second suction cup 23 to adsorb and fix the tape to prevent the tape from falling off the one-way wheel 19. For details, refer to Figure 2 , Figure 5 and Fig. 9 As shown, the front and rear ends of the rotating plate 20 away from the moving plate 15 are fixedly connected with a connecting plate 21, and an arc plate 22 is arranged inside the connecting plate 21, a cutting blade 26 is connected to the inside of the connecting plate 21 below the arc plate 22, and a second tooth block is fixed at an equal angle to the top of the cutting blade 26, and a driving gear 27 is connected to the inside of the connecting plate 21 between the arc plate 22 and the cutting blade 26 through an axis rotation, a motor is installed below the back of the connecting plate 21, and the output end of the motor is fixedly connected to the shaft end of the driving gear 27, the first rack 24 is slidably connected to the inside of the cavity, and the outer side of the second piston block 25 is connected to the inner wall of the cavity. The second suction cup 23 is connected with the inside of the cavity in a sealed sliding connection, the second suction cup 23 is connected with the inside of the cavity, the moving directions of the first rack 24 and the cutting blade 26 are opposite, a cavity is opened inside the arc plate 22, and the inside of the cavity is connected with the first rack 24, a second piston block 25 is fixed to the right end of the first rack 24, and the second suction cup 23 is installed on the right end of the arc plate 22, the driving gear 27 and the first rack 24 and the cutting blade 26 are meshed and connected, both ends of the cutting blade 26 extend out of the outer surface of the connecting plate 21, and the cutting blade 26 is connected with the connecting plate 21 in a sliding connection, and the cutting blade 26 is arranged in a circular arc shape;

[0047] However, after the tape is pasted, the motor is started, and the motor drives the driving gear 27 to rotate, so that the driving gear 27 drives the meshing second tooth block and the cutting blade 26 to move to the right, thereby automatically cutting the tape. At the same time, the driving gear 27 drives the first rack 24 to move to the left, and drives the second piston block 25 to move to the left inside the cavity, so that the second suction cup 23 generates negative pressure and adsorbs and fixes the tape, so that the tape is always wrapped around the one-way wheel 19 to prevent it from falling off after cutting. Then, when the one-way wheel 19 is reset, the motor drives the driving gear 27 to rotate in the opposite direction. At this time, the cutting blade 26 moves to the left and resets. At the same time, the second suction cup 23 is released and no longer fixes the tape.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
