Description

Technical Field

[0001] The invention relates to the technical field of packaging, and in particular to a finished product packaging machine for graphics card heat sinks. Background Art

[0002] The finished graphics card heat sink is packaged in a packaging box. The packaging box is a packaging product made of honeycomb paperboard, which is made by punching, cutting and pasting the honeycomb paperboard. The packaging box is sealed by pasting tape on the cardboard at the port of the packaging box. This is mainly for the convenience of transportation, loading and unloading and warehousing. It has the advantages of fast assembly, time-saving and labor-saving, exquisite workmanship, good sealing performance, and can save a large amount of wood resources. It is an internationally recognized and promoted new environmentally friendly packaging product. In the actual sealing process, it is usually necessary to glue and seal the packaging box. The packaging box is transported by a conveyor belt, and then the staff glues and seals the port of the packaging box so that the port of the packaging box is sealed to achieve a closed effect, so that the sealing is completed to meet the requirements of transportation, loading and unloading and warehousing.

[0003] There are four cardboards at the port of a common packaging box. The four cardboards are located on the four sides of the port of the packaging box, with two longer cardboards facing each other and two shorter cardboards facing each other. When sealing, the two shorter cardboards are folded first, and then the two longer cardboards are folded. The two shorter cardboards are located under the two longer cardboards, and the two longer cardboards are bonded with tape, and the two ends of the tape extend downward and bonded to the outside of the packaging box.

[0004] In the process of gluing and sealing the packaging boxes containing the finished graphics card heat sinks, manually sealing the packaging boxes with tape is inefficient, has high labor input costs, and is labor-intensive.

[0005] When the existing partially automatic tape sealing device seals the packaging box, the tape is attached to the longer cardboard at the port of the packaging box, and then the tape is rolled by a pressure roller to improve the bonding strength between the tape and the longer cardboard at the port of the packaging box. However, when the tape is squeezed by the pressure roller, in order to improve the bonding strength of the tape to the longer cardboard, the pressure of the pressure roller on the longer cardboard is large and the pressure remains constant. However, since the two shorter cardboards can support the two ends of the longer cardboard respectively, the pressure bearing capacity of the ends of the longer cardboard is greater than the pressure bearing capacity of the middle part of the longer cardboard. When the pressure roller rolls the middle part of the longer cardboard, the middle part of the longer cardboard is prone to collapse downward, resulting in the tape being unable to be effectively bonded to the longer cardboard. For this reason, a packaging machine that can ensure the bonding strength between the tape and the longer cardboard at the port of the packaging box is required. Summary of the invention

[0006] The main purpose of the present invention is to provide a graphics card heat sink finished product packaging machine which can improve the bonding strength between the adhesive tape and the longer cardboard at the end of the packaging box.

[0063] A second longitudinal rod 30 is fixed on the connecting plate 26, a pressure sensor 28 is fixed on the side of the connecting plate 26 facing the push rod 29, a first magnetic block 27 is fixed on the force-bearing end of the pressure sensor 28, and the first magnetic block 27 corresponds to the push rod 29. In this embodiment, there are two second longitudinal rods 30, and the two second longitudinal rods 30 are symmetrically arranged front and back.

[0064] The end of the second longitudinal rod 30 is slidably disposed in the first slideway 19. In this embodiment, there are two first slideways 19, which are symmetrically disposed front and back, and are respectively fixed on the front and back inner walls of the mounting frame 7. The two second longitudinal rods 30 are slidably disposed in the two first slideways 19, respectively.

The second magnetic block 31 magnetically attracts the second slideway 21. When the limit plate 22 moves in the second slideway 21, it has sliding damping.

[0066] In this embodiment, there are two second slideways 21, which are symmetrically arranged front and back, and are respectively fixed on the front and back inner walls of the mounting frame 7. The front and back ends of the limit plate 22 are respectively slidably arranged in the second slideways 21 on the front and back sides. There are two second magnetic blocks 31, which are respectively fixed on the front and back ends of the limit plate 22. The two second magnetic blocks 31 are respectively located in the two second slideways 21.

[0067] The second slideway 21 is located below the first slideway 19. The first slideway 19 and the second slideway 21 are flush with one end close to the stop assembly. The length of the second slideway 21 is greater than that of the first slideway 19. The middle part of the first slideway 19 bulges upward.

[0068] The pressure sensor 28, the suction cup 24 and the controller are electrically connected.

[0069] An L-shaped baffle 20 is fixed in the mounting frame 7 on one side of the first slide 19. The baffle 20 is located above the second slide 21. A gap is provided between the straight portion of the baffle 20 and the first slide 19. The width of the gap is greater than the diameter of the first longitudinal rod 18. The second longitudinal rod 30 can be blocked by the straight portion of the baffle 20 after withdrawing from the first slide 19.

[0070] After the lower end of the packaging box 34 is sealed, the finished graphics card heat sink is placed in the packaging box 34, and then the packaging box 34 is placed in the center of the fixed frame 2. After the packaging box 34 is placed in the center of the fixed frame 2, there is a space between the left end of the fixed frame 2 and the left end of the packaging box 34, and there is a space between the right end of the fixed frame 2 and the right end of the packaging box 34.

[0071] The vacuum pump 3 is started, and the vacuum pump 3 can generate negative pressure in the through hole and absorb the side wall of the packaging box 34 on one side thereof, thereby positioning the packaging box 34 placed in the fixing frame 2 .

[0072] After placing the finished graphics card heat sink into the packaging box 34, close the two shorter cardboards at the upper end of the packaging box 34, and then close the two longer cardboards at the upper end of the packaging box 34, so that the two shorter cardboards at the upper end of the packaging box 34 are located below the two longer cardboards at the upper end of the packaging box 34.

[0073] When the conveying unit is started to convey the fixed frame 2 and the packaging box 34 toward the sealing device, the roller 6 rolls in contact with the two longer cardboards at the upper end of the packaging box 34 , and the roller 6 can limit the two longer cardboards at the upper end of the packaging box 34 .

[0074] When the packaging box 34 is located below the left side of the pressing roller 17, the conveying portion of the conveying member 1 is closed.

[0075] like Fig.13 As shown, the first telescopic rod 11 is then started, so that the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17 and the tape roller 15 move downward until the pressure roller 17 is located on the right side of the packaging box 34.

[0076] The adhesive tape 35 wound from the adhesive tape roller 15 is adhered to the right side wall of the packaging box 34. At this time, the adhesive tape 35 corresponds to the gap between the two longer cardboards at the upper end of the packaging box 34, and the lower ends of the two suction cups 24 are respectively in contact with the upper ends of the two longer cardboards at the upper end of the packaging box 34, and the suction cups 24 can prevent the two longer cardboards at the upper end of the packaging box 34 from rotating upward.

[0077] Then start the motor 10, the motor 10 drives the screw rod to rotate, and when the screw rod 9 rotates, the first telescopic rod 11, the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17 and the tape roller 15 are close to the right side wall of the packaging box 34.

[0078] When the pressure roller 17 contacts the right side wall of the packaging box 34, the motor 10 is turned off, and then the first telescopic rod 11 is started, so that the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17 and the tape roller 15 move upward.

[0079] During the upward movement of the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17 and the tape roller 15, the tape 35 gradually adheres to the right side wall of the packaging box 34, and the pressure roller 17 can roll the tape 35 adhered to the right side wall of the packaging box 34.

[0080] When the first telescopic rod 11 drives the connecting rod 13 , the first longitudinal rod 18 , the second fork rod 16 , the first fork rod 14 , the push rod 29 , the pressure roller 17 and the tape roller 15 to move upward to the top dead point, the first longitudinal rod 18 corresponds to the first slideway 19 .

[0081] Then the motor 10 is started, so that the motor 10 drives the lead screw to rotate. When the lead screw 9 rotates, the first telescopic rod 11, the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17 and the tape roller 15 move to the left direction, and the tape 35 gradually adheres to the two longer cardboards at the upper end of the packaging box 34. The pressure roller 17 rolls with the two longer cardboards at the upper end of the packaging box 34 and crushes the tape 35 adhered to the two longer cardboards at the upper end of the packaging box 34.

[0082] During the movement of the first telescopic rod 11, the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17 and the tape roller 15 to the left, when the push rod 29 presses the first magnetic block 27, the pressure on the pressure sensor 28 increases. At the same time, the first magnetic block 27 magnetically attracts the push rod 29. After the pressure on the pressure sensor 28 increases, the pressure sensor 28 sends a signal to the controller, and the controller starts the suction cup 24, which negatively attracts the longer cardboard at the upper end of the packaging box 34 on one side.

[0083] During the subsequent movement of the first telescopic rod 11, the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17 and the tape roller 15 toward the left, the connecting plate 26, the second longitudinal rod 30, the sliding rod 23, the limiting plate 22, the second magnetic block 31 and the suction cup 24 move toward the left together, and the suction cup 24 makes sliding contact with the longer cardboard at the upper end of the packaging box 34 on one side thereof and maintains negative pressure adsorption on the longer cardboard at the upper end of the packaging box 34.

[0084] Since the middle portion of the first slide 19 protrudes upward, under the guiding effect of the first slide 19 on the second longitudinal rod 30 and the first longitudinal rod 18 , the suction cup 24 and the pressure roller 17 can both move upward during the movement toward the middle portion of the packaging box 34 .

[0085] During the movement of the two suction cups 24 toward the middle of the packaging box 34, the second longitudinal rod 30 moves in the first slideway 19 toward the middle of the first slideway 19, and the heights of the second longitudinal rod 30 and the connecting plate 26 gradually increase. During the gradual increase of the heights of the second longitudinal rod 30 and the connecting plate 26, the connecting plate 26 causes the slide bar 23 and the suction cup 24 to gradually move upward through the second spring 25. During the gradual upward movement of the suction cup 24, the two longer cardboards at the upper end of the packaging box 34 can be flipped upward.

[0086] When the pressing roller 17 moves toward the middle of the packaging box 34, the first longitudinal rod 18 moves in the first slideway 19 toward the middle of the first slideway 19, and the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the tape roller 15, the pressing roller 17 and the push rod 29 gradually move upward, and the first spring 12 is compressed. When the height of the pressing roller 17 gradually increases, the pressure of the pressing roller 17 on the two longer cardboards at the upper end of the packaging box 34 can be gradually reduced, and the pressure applied by the pressing roller 17 to the middle of the two longer cardboards at the upper end of the packaging box 34 can be prevented from being too great, causing the middle of the two longer cardboards at the upper end of the packaging box 34 to collapse.

[0087] When the pressure of the pressure roller 17 on the two longer cardboards at the upper end of the packaging box 34 is gradually reduced, the two longer cardboards at the upper end of the packaging box 34 can be turned upward during the movement of the suction cup 24. When the pressure of the pressure roller 17 on the longer cardboard at the upper end of the packaging box 34 is gradually reduced, the pressure between the longer cardboard at the upper end of the packaging box 34 and the pressure roller 17 can be ensured, thereby ensuring the bonding force between the adhesive tape 35 and the two longer cardboards at the upper end of the packaging box 34.

[0088] When the heights of the second longitudinal rod 30, the connecting plate 26, the slide bar 23 and the suction cup 24 gradually increase, the pressing roller 17 blocks the longer cardboard at the upper end of the packaging box 34. Since the upper end of the slide bar 23 is connected to the lower end of the connecting plate 26 by the second spring 25, the second spring 25 can play a certain buffering role on the slide bar 23 and the suction cup 24, preventing the suction cup 24 from causing the longer cardboard at the upper end of the packaging box 34 to flip over too much and cause the longer cardboard at the upper end of the packaging box 34 to be torn.

[0089] When the pressing roller 17 moves to the left side of the packaging box 34, the second longitudinal rod 30 passes over the gap between the baffle 20 and the first slide 19 and moves to the top of the straight portion of the baffle 20, and the baffle 20 blocks the second longitudinal rod 30. At this time, the first longitudinal rod 18 corresponds to the gap between the baffle 20 and the first slide 19. Since the first magnetic block 27 magnetically adsorbs the push rod 29, the second longitudinal rod 30 cannot move downward and pass through the gap between the baffle 20 and the first slide 19 when the second longitudinal rod 30 is located above the gap between the baffle 20 and the first slide 19.

[0090] like Fig.15As shown, the motor 10 is then turned off and the first telescopic rod 11 is started, so that the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17 and the tape roller 15 move downward. During the downward movement of the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17 and the tape roller 15, the tape 35 gradually adheres to the left side wall of the packaging box 34, and the pressure roller 17 can crush the tape 35 adhered to the left side wall of the packaging box 34.

[0091] Then start the second telescopic rod 32, the cutter 33 moves toward the adhesive tape 35 and cuts off the adhesive tape 35. So far, the adhesive tape 35 seals the upper end of the packing box 34.

[0092] After the adhesive tape 35 seals the upper end of the packaging box 34, the conveying part of the conveying member 1 is started to transfer the fixed frame 2 and the packaging box 34 out of the mounting frame 7. After the vacuum pump 3 is turned off, the packaging box 34 in the fixed frame 2 can be taken out.

[0093] After the tape 35 seals the upper end of the packaging box 34, the first telescopic rod 11 is started, so that the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17 and the tape roller 15 move upward. When the first longitudinal rod 18 passes through the gap between the baffle 20 and the first slide 19 and corresponds to the left port of the first slide 19, the first telescopic rod 11 is closed.

[0094] Then start the motor 10, so that the motor 10 drives the lead screw 9 to rotate in the opposite direction, thereby causing the first telescopic rod 11, the connecting rod 13, the first longitudinal rod 18, the second fork rod 16, the first fork rod 14, the push rod 29, the pressure roller 17, the tape roller 15, the connecting plate 26, the second longitudinal rod 30, the slide bar 23, the limit plate 22, the second magnetic block 31 and the suction cup 24 to move to the right together. During the movement of the push rod 29 to the right, the first magnetic block 27 is pulled, and the force-bearing end of the pressure sensor 28 is no longer subjected to pressure. The controller closes the suction cup 24, ensuring that the conveying portion of the conveying member 1 can smoothly convey the fixed frame 2 and the packaging box 34 therein to the outside of the mounting frame 7.

[0095] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
