Description

Technical Field

[0001] This invention relates to the field of packaging, specifically to an intelligent ointment box packaging device and its process. Background Technology

[0002] Ointment boxing packaging equipment is a mechanical device used to automatically fill ointment products into packaging boxes. This equipment is widely used in the pharmaceutical, daily chemical and other related industries to meet the packaging needs of various ointment products. In the pharmaceutical field, this equipment can be used to package various ointment drugs, such as antibacterial ointments, antifungal ointments, etc.

[0003] The equipment typically operates as an automated production line. It first places the flattened packaging box on the conveyor belt of the equipment, then unfolds the packaging box through compression. Next, a robotic arm or pusher grabs or pushes the ointment product into the packaging box. Finally, the lid of the packaging box is sealed and sent out of the equipment, completing the entire packaging process.

[0004] Existing double-lid packaging boxes have a main lid and two flaps on both sides. When the boxes are closed normally, the main lid uses a tongue to insert into the gap between the two flaps and one side of the box to engage with them. However, when the existing ointment box packaging equipment is used for the closing operation, the tongue of the main lid may not be properly inserted into the gap between the main lid and the flaps. Instead, the tongue may push against the flaps on one or even both sides during the closing process. In this case, the tongue and flaps will deform, and during subsequent side re-pressing, the tongue and flaps will continue to stick together in a deformed form, thus creating the illusion that the boxes are closed. However, the tongue and flaps are not actually engaged. During subsequent transportation, the ointment may be able to be pushed open and the main lid may fall off. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an intelligent ointment box packaging device and its process. The device comprises an ointment conveyor belt and a box conveyor belt arranged parallel to each other on the machine body. The ointment conveyor belt and the box conveyor belt have adjacent material mixing zones, and a box-packing push rod is provided on the ointment conveyor belt in the material mixing zone. A cover-opening guide rod and a cover-closing mechanism are respectively arranged in front of the material mixing zone and the next-level box conveyor belt. The end of the box conveyor belt is provided with a double-pressure discharge conveyor belt for planar extrusion of both sides of the packaging box.

[0006] The lid-closing mechanism includes a lid-closing rocker, a lid-squeezing rod, a lid-closing guide rod, a tongue-pulling plate, and a tongue-fixing plate arranged sequentially along the production direction. The front ends of the tongue-pulling plate and the front ends of the tongue-fixing plate are respectively provided with a tongue-pressing plate and a lid-closing adjustment assembly via a reciprocating arm. The lid-closing adjustment assembly includes a lid-closing plate mounted on the reciprocating arm. The lid-closing plate is driven by the reciprocating arm to squeeze the lid of the packaging box into the packaging box so that the tongue is inserted into the packaging box.

[0007] The bottom end of the lid plate is provided with a lid adjustment component that is inserted into the interlocking gap between the lid and the tongue and is inserted into the packaging box along with the lid and contacts the hinged lid. The lid adjustment component is inserted into the interlocking gap by swinging from the side end of the interlocking gap and is pulled out from the interlocking gap by linear movement.

[0008] The adjustable lid assembly includes a hook plate that can swing and unfold, and the hook plate abuts against the inside of the hinged lid of the packaging box during the outward pulling process;

[0009] There is a gap between the bottom end of the adjusting lid assembly and the fixed tongue plate that is smaller than the thickness of the tongue. The tongue moves against the fixed tongue plate under the pressure of the adjusting lid assembly. The horizontal height of the top surface of the fixed tongue plate that supports the tongue is higher than the height of the bottom inner wall of the packaging box.

[0010] Furthermore, the cover adjustment assembly also includes a swing arm assembly. The cover adjustment assembly is connected to the swing arm assembly via a positioning rocker arm. The swing arm assembly is installed at the bottom of the cover plate via a mounting bracket. The mounting bracket has a swing arm assembly, a positioning rocker arm, and a cover adjustment assembly on both sides.

[0011] The adjusting lid assembly swings through the swing arm assembly and moves into the interlocking gap between the lid and the tongue on the fixed tongue plate.

[0012] The adjusting cover assembly is slidably mounted on the positioning rocker arm and is pulled out from the interlocking seam by linear movement on the positioning rocker arm.

[0013] Furthermore, the swing arm assembly includes an active swing arm and a synchronous swing arm. The inner ends of the active swing arms on both sides are provided with gears on the inner side of the mounting frame, and the active swing arms on both sides move synchronously through gear meshing. The outer ends of the active swing arms are hinged to the positioning rocker arm.

[0014] The inner end of the synchronous swing arm is hinged to the mounting frame, while the outer end is hinged to the positioning rocker arm. The gear part of the active swing arm is connected to the drive motor on the mounting frame.

[0015] Furthermore, the synchronous swing arm and the active swing arm are parallel and their two ends are respectively combined with the positioning rocker arm and the mounting frame to form a parallelogram linkage mechanism;

[0016] The furthest distance between the outer ends of the two active swing arms is greater than the width of the packaging box.

[0017] Furthermore, the adjusting cover assembly also includes a sliding pressure plate slidably mounted on the positioning rocker arm, the pressure hook plate is mounted on the sliding pressure plate via a rotating shaft, and the tongue moves against the fixed tongue plate under the pressure of the sliding pressure plate.

[0018] The positioning rocker arm is provided with a limiting guide wall, the limiting guide wall is provided with a guide groove, and the rotating shaft is provided with a driven pin that moves in the guide groove. The guide groove guides the rotating shaft to rotate, so that the pressure hook plate abuts against the inside of the packaging box's flap during the outward pulling process.

[0019] Furthermore, the swing arm assembly includes a movable swing arm, and a slide block is slidably mounted on the mounting frame. The inner end of the movable swing arm is hinged to the slide block, and the outer end is hinged to the adjusting cover assembly.

[0020] The mounting bracket is equipped with a push-pull component connected to the slide block, and the adjusting cover assembly slides on the positioning rocker arm via the push-pull component.

[0021] Furthermore, the guide groove on the limiting guide wall includes an unfolding groove for guiding the unfolding of the hook plate, a translation groove for guiding the hook plate to remain in the unfolded state when it is pulled out, and a reset groove for guiding the unfolded hook plate to reset.

[0022] Furthermore, the length of the guide groove is less than the length of the translation pressure plate extending into the packaging box.

[0023] A smart box-packaging process for ointments includes the following steps:

[0024] Step 1: The ointment conveyor belt and the box conveyor belt transport ointment and packaging boxes at intervals. At the material collection area, the boxing pusher pushes the ointment on the ointment conveyor belt into the packaging box on the box conveyor belt. The box conveyor belt continues to transport and stops at each station.

[0025] Step two: The box conveyor belt carries the packaging box to the position of the closing claw and the squeezing rod and stops. The flap closest to the squeezing rod is squeezed by the squeezing rod and swings into the packaging box. At this time, the closing claw swings and squeezes the other flap into the packaging box. Then the box conveyor belt continues to move, guiding the box cover downward through the closing guide rod and pressing the tongue against the guide plate position and stopping. The tongue pressing plate squeezes the tongue on the guide plate and bends it. Then the box conveyor belt continues to move, allowing the bent tongue to move to the fixed tongue plate position and stop. At this time, the packaging box is in the ready-to-close state on the fixed tongue plate.

[0026] Step 3: The lid adjustment assembly swings through the swing arm assembly and moves into the interlocking gap between the lid and the tongue on the fixed tongue plate. Then, the lid closing plate moves towards the lid, causing the lid to be pressed into the packaging box. The lid adjustment assembly moves synchronously with the lid closing plate. The tongue is pressed against the fixed tongue plate by the sliding pressure plate and moves. The lid adjustment assembly presses the tongue into the packaging box.

[0027] Step four: After the tongue enters the packaging box, the push-pull component drives the translation pressure plate to be pulled outward. Under the guidance of the guide groove, the pressure hook plate unfolds and causes the rocker cover to swing outward, so that the interlocking seam and the interlocking protrusion interlock. After reaching the required position, the pressure hook plate swings back to horizontal and is pulled out from the interlocking seam. At this time, the closing plate continues to abut against the box cover until the pressure hook plate is pulled out and the closing plate retracts to its original position. After the closing is completed, the box conveyor belt continues to move and sends the packaging box containing ointment into the repressing discharge conveyor belt to flatten both sides of the packaging box again.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] This invention provides a lid adjustment assembly at the bottom of the lid plate. The assembly of the swing arm allows the lid to swing and insert into the interlocking gap. During the process of the lid plate pressing the lid into the packaging box, the translational pressure plate of the lid adjustment assembly presses down on the tongue. The lid adjustment assembly also restricts the tongue's freedom to swing excessively upward, thus ensuring that the tongue is fixedly attached to the top surface of the tongue plate when it enters the packaging box. This prevents the common situation where the tongue swings upward during lid closing, causing significant pressure on the lid.

[0030] During the lid-closing operation, the sliding pressure plate moves along with the hook plate into the packaging box. Then, the sliding pressure plate is pulled outwards, and the guide groove on the limiting guide wall guides the hook plate to unfold and causes the rocker lid to swing outwards, thereby making the interlocking seam and the interlocking protrusion engage. After reaching the desired position, the hook plate swings back to horizontal and is pulled out from the interlocking seam. At this time, the lid-closing plate continues to abut against the box lid until the hook plate is pulled out, at which point the lid-closing plate retracts and resets, thus ensuring the degree of engagement between the box lid and the rocker lid and preventing the box lid's tongue from squeezing the rocker lid during the closing process, which would result in a loose lid. After the lid is closed, the box conveyor belt continues to move, sending the packaging box containing the ointment into the re-pressing discharge conveyor belt to flatten both sides of the packaging box.

[0044] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Examples, such as Figures 1-9As shown: This invention provides an intelligent ointment box packaging device. The packaging box A used in this packaging device is a double-lid A4 packaging box. Two flaps A4 and a box cover A2 are provided at the openings at both ends of the main body of the packaging box A, which occupy three sides of the opening respectively. The remaining side is the insertion point of the tongue A2 at the end of the box cover A2. There are interlocking seams A3 on both sides between the box cover A1 and the tongue A2. The interlocking seams A3 are used to engage with the interlocking protrusions A5 of the two flaps A4 after being inserted into the packaging box A, so that the box cover A2 is fastened to the two flaps A4 and the two sides of the packaging box A are covered.

[0046] The packaging equipment structure includes an ointment conveyor belt 1 and a box conveyor belt 3 arranged parallel to each other on the machine body on the same horizontal plane. The ointment conveyor belt 1 and the box conveyor belt 3 are respectively provided with a partition plate 11 and a partition rack 31 for separating the transport of ointment and packaging box A. The ointment conveyor belt 1 and the box conveyor belt 3 have adjacent material mixing areas a and a boxing push rod 2 is provided on the ointment conveyor belt 1 in the material mixing area a. The boxing push rod 2 is used to push the ointment on the ointment conveyor belt 1 into the packaging box of the box conveyor belt 3.

[0047] A lid-opening guide rod b and a lid-closing mechanism 4 are respectively arranged in front of the material mixing area a and the next-level box conveyor belt 3. The lid-opening guide rod b is used to guide the lid A2 of the packaging box A to open so that the ointment can enter. The lid-closing mechanism 4 is responsible for closing the lid A2 and the hinged lid A4 of the packaging box A. The lid-closing mechanism 4 includes a lid-closing claw 42, a lid-squeezing rod 41, a lid-closing guide rod 43, a tongue-pulling plate 44, and a tongue-fixing plate 46 arranged sequentially along the production direction. The lid-closing claw 42 is connected to a reciprocating arm 6 that swings back and forth. When the packaging box A moves to the lid-closing claw 42 and the lid-squeezing rod 41, the hinged lid A4 closest to the lid-squeezing rod 41 is squeezed by the lid-squeezing rod 41 and swings into the packaging box A. At this time, the lid-closing claw 42 swings and closes the other hinged lid. The lid A4 is pressed into the packaging box A, and then the lid A2 is guided downward by the lid closing guide rod 43 and the tongue A2 is pressed against the tongue guide plate 44. Then, the front end of the tongue guide plate 44 and the front end of the fixed tongue plate 46 are respectively provided with a tongue pressing plate 45 and a lid closing adjustment component 7 via a linear reciprocating arm 6. The tongue pressing plate 45 presses the tongue A2 on the tongue guide plate 44 to bend it, and then moves the bent tongue A2 to the fixed tongue plate 46. Thus, the packaging box A is in a ready-to-close state on the fixed tongue plate 46. The lid closing and adjustment operations are performed by the lid closing adjustment component 7. After the lid is closed, the end of the box conveyor belt 3 is provided with a re-pressing discharge conveyor belt 5 for flattening the two sides of the packaging box A.

[0048] It should be noted that those skilled in the art know the execution mode of the reciprocating arm 6, whether it is a swing reciprocating type or a linear reciprocating type, while the repressing discharge conveyor belt 5 is a synchronous conveyor belt with a fixed spacing on both sides, which clamps the package box A after it is closed and sends it out. Those skilled in the art can use a repressing discharge conveyor belt 5 with heating as needed.

[0049] The lid adjustment assembly 7 includes a lid plate 71 mounted on a reciprocating arm 6. The lid plate 71 is driven by the reciprocating arm 6 to press the lid A1 of the packaging box A into the packaging box A so that the tongue A2 is inserted into the packaging box A. In this embodiment, the bottom end of the lid plate 71 is provided with a lid adjustment assembly 75 that is inserted into the interlocking gap A3 between the lid A1 and the tongue A2 and follows the lid A1 into the packaging box A and contacts the swing cover A4. The lid adjustment assembly 75 is inserted into the interlocking gap A3 by swinging from the side end of the interlocking gap A3 and is pulled out from the interlocking gap A3 by linear movement. The lid adjustment assembly 75 includes a hook plate 752 that can be swinged and unfolded. During the outward pulling process, the hook plate 752 abuts against the inner side of the swing cover A4 of the packaging box A.

[0050] Therefore, in order to insert the cover assembly 75 into the interlocking slot A3 to compress the guide tongue A2, and to cause the cover A4 to press against the box cover A1 during the withdrawal process so that the interlocking slot A3 and the interlocking protrusion A5 engage, in this embodiment:

[0051] For the entry part, there is a gap between the bottom end of the adjusting lid assembly 75 and the fixed tongue plate 46 that is smaller than the thickness of the tongue A2. The tongue A2 moves against the fixed tongue plate 46 under the pressure of the adjusting lid assembly 75, so that the tongue A2 is fixedly attached to the top surface of the fixed tongue plate 46. The adjusting lid assembly 75 restricts the degree of freedom of the tongue A2 to swing upward excessively, preventing the common situation where the tongue A2 swings upward when the lid is closed, thus greatly squeezing the flap A4. The horizontal height of the top surface of the fixed tongue plate 46 that supports the tongue A2 is higher than the height of the bottom inner wall of the packaging box A. At the same time, it is known that it will also be lower than the bottom edge of the flap A4. The optimal position is within the range of the upper and lower parts of the biting protrusion A5.

[0052] Meanwhile, the cover adjustment assembly 75 also includes a swing arm assembly 73. The cover adjustment assembly 75 is connected to the swing arm assembly 73 via a positioning rocker arm 72. The swing arm assembly 73 is mounted on the bottom end of the cover plate 71 via a mounting bracket 74. The mounting bracket 74 has a swing arm assembly 73, a positioning rocker arm 72, and a cover adjustment assembly 75 on both sides. The cover adjustment assembly 75 swings through the swing arm assembly 73 and moves into the engagement seam A3 between the cover A1 and the tongue A2 on the fixed tongue plate 46. Specifically, the swing arm assembly 73 includes an active swing arm 731 and a synchronous swing arm 732. The inner ends of the active swing arms 731 on both sides are provided with gears on the inner side of the mounting bracket 74. The gear parts of the active swing arms 731 are connected to the drive motor 77 on the mounting bracket 74. The active swing arms 731 on both sides move synchronously through gear meshing. The outer ends of the active swing arms 731 are hinged to the positioning rocker arm 72. The inner end of the synchronous swing arm 732 is hinged to the mounting frame 74 and the outer end is hinged to the positioning rocker arm 72. In this embodiment, the synchronous swing arm 732 and the active swing arm 731 are parallel and their two ends are respectively combined with the positioning rocker arm 72 and the mounting frame 74 to form a parallelogram linkage mechanism.

[0053] Therefore, by setting the farthest distance of the outer ends of the two active swing arms 731 to be greater than the width of the packaging box A, the positioning rocker arm 72, driven by the drive motor 77, swings from the side of the box cover A1 and inserts into the interlocking seam A3. Then, the closing plate 71 moves toward the box cover A1, causing the box cover A1 to be pressed into the packaging box A. The closing plate 75 is synchronized with the closing plate 71. The tongue A2 moves against the fixed tongue plate 46 under the pressure of the translation pressure plate 751. The closing plate 75 presses the tongue A2 into the packaging box A.

[0054] For the extraction portion, the cover adjustment assembly 75 also includes a translation pressure plate 751 slidably mounted on the positioning rocker arm 72. The translation pressure plate 751 of the cover adjustment assembly 75 is slidably mounted on the positioning rocker arm 72 and is extracted from the interlocking seam A3 by linear movement on the positioning rocker arm 72. Specifically, the swing arm assembly 73 includes a movable swing arm 733, and a slide seat 76 is slidably mounted on the mounting bracket 74. The inner end of the movable swing arm 733 is hinged to the slide seat 76, and the outer end is connected to the cover adjustment assembly 75. The translation pressure plate 751 of 5 is hinged. The mounting bracket 74 is provided with a push-pull member 78 connected to the slide block 76. The cover adjustment assembly 75 slides on the reaching rocker arm 72 through the push-pull member 78, so that the cover adjustment assemblies 75 on both sides can be controlled by driving the slide block 76. And the reaching rocker arm 72 will not affect the cover adjustment assembly 75 when it swings. It can be seen that for the fixed position of the cover adjustment assembly 75 on the reaching rocker arm 72, a spring opposite to the pulling direction can be set.

[0055] In this embodiment, the push-pull component 78 is an electromagnet. When implementing this, those skilled in the art can add an inductor to the electromagnet circuit to increase the time constant, thereby extending the electromagnet's action time to avoid it being too fast. Those skilled in the art can also use other solutions, as long as the push-pull function is achieved at the required speed.

[0056] Meanwhile, the hook plate 752 is mounted on the translational pressure plate 751 via the rotating shaft 753. The positioning rocker arm 72 is provided with a limiting guide wall 721, and the limiting guide wall 721 is provided with a guide groove. The rotating shaft 753 is provided with a driven pin that moves in the guide groove. The guide groove guides the rotating shaft 753 to rotate, so that the hook plate 752 abuts against the inside of the flap A4 of the packaging box A during the outward pulling process. The guide groove on the limiting guide wall 721 includes an unfolding groove 722 for guiding the hook plate 752 to unfold, a translational groove 723 for guiding the hook plate 752 to remain unfolded when pulled out, and a reset groove 724 for guiding the unfolded hook plate 752 to reset.

[0057] Therefore, after the tongue A2 enters the packaging box A, the push-pull component 78 drives the slide 76 to slide, and the moving arm 733 pulls the translation pressure plate 751 outward. By setting the length of the guide groove to be less than the length of the translation pressure plate 751 extending into the packaging box A, under the guidance of the guide groove, the unfolded hook plate 752 drives the rocker cover A4 to swing outward, so that the interlocking seam A3 and the interlocking protrusion A5 are engaged. After reaching the required position, the reset groove 724 drives the hook plate 752 to swing back to the horizontal and pull it out from the interlocking seam A3. At this time, the closing cover 71 continues to abut against the box cover A2 until the hook plate 752 is pulled out and then the closing cover 71 retracts to its reset position.

[0058] In summary, this embodiment also provides an intelligent box-packaging process for ointments, including the following steps:

[0059] Step 1: Ointment conveyor belt 1 and box conveyor belt 3 transport ointment and packaging box A at intervals. At the material mixing area a, the boxing pusher 2 pushes the ointment on ointment conveyor belt 1 into the packaging box on box conveyor belt 3. Box conveyor belt 3 continues to transport and stops at each station.

[0060] Step 2: The box conveyor belt 3 carries the packaging box A to the position of the closing claw 42 and the squeezing rod 41 and stops. The flap A4 closest to the squeezing rod 41 is squeezed by the squeezing rod 41 and swings into the packaging box A. At this time, the closing claw 42 swings and squeezes the other flap A4 into the packaging box A. Then the box conveyor belt 3 continues to move and guides the box cover A2 downward through the closing guide rod 43 and presses the tongue A2 to the position of the tongue guide plate 44 and stops. The tongue press plate 45 squeezes the tongue A2 on the tongue guide plate 44 and bends it. Then the box conveyor belt 3 continues to move and moves the bent tongue A2 to the position of the fixed tongue plate 46 and stops. At this time, the packaging box A is in the ready-to-close state on the fixed tongue plate 46.

[0061] Step 3: The adjusting lid assembly 75 swings through the swing arm assembly 73 and moves into the interlocking seam A3 between the lid A1 and the tongue A2 on the fixed tongue plate 46. Then, the closing lid plate 71 moves toward the lid A1, causing the lid A1 to be pressed into the packaging box A. The adjusting lid assembly 75 moves synchronously with the closing lid plate 71. The tongue A2 moves against the fixed tongue plate 46 under the pressure of the translation pressure plate 751. The adjusting lid assembly 75 presses the tongue A2 into the packaging box A.

[0062] Step four: After the tongue A2 enters the packaging box A, the push-pull component 78 drives the translation pressure plate 751 to be pulled outward. Under the guidance of the guide groove, the pressure hook plate 752 unfolds and drives the rocking cover A4 to swing outward, so that the interlocking seam A3 and the interlocking protrusion A5 are engaged. After reaching the required position, the pressure hook plate 752 swings back to horizontal and is pulled out from the interlocking seam A3. At this time, the closing cover plate 71 continues to abut against the box cover A2 until the pressure hook plate 752 is pulled out and the closing cover plate 71 is retracted and reset. After the closing is completed, the box conveyor belt 3 continues to move and sends the packaging box A containing ointment into the repressing discharge conveyor belt 5 to flatten both sides of the packaging box A again.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The inner end of the movable swing arm is hinged to the slide block, and the outer end is hinged to the adjusting cover assembly. The mounting bracket is equipped with a push-pull component connected to the slide block, and the adjusting cover assembly slides on the positioning rocker arm via the push-pull component.

5. The intelligent ointment box packaging equipment according to claim 4, characterized in that: The guide groove on the limiting guide wall includes an unfolding groove for guiding the unfolding of the hook plate, a translation groove for guiding the hook plate to remain in the unfolded state when it is pulled out, and a reset groove for guiding the unfolded hook plate to reset.

6. The intelligent ointment box packaging equipment according to claim 5, characterized in that: The length of the guide groove is less than the length of the translation pressure plate that extends into the packaging box.

7. A smart box-packing process for ointments, characterized in that: Packaging using the intelligent ointment box packaging equipment as described in claim 6 includes the following steps: Step 1: The ointment conveyor belt and the box conveyor belt transport ointment and packaging boxes at intervals. At the material collection area, the boxing pusher pushes the ointment on the ointment conveyor belt into the packaging box on the box conveyor belt. The box conveyor belt continues to transport and stops at each station. Step two: The box conveyor belt carries the packaging box to the position of the closing claw and the squeezing rod and stops. The flap closest to the squeezing rod is squeezed by the squeezing rod and swings into the packaging box. At this time, the closing claw swings and squeezes the other flap into the packaging box. Then the box conveyor belt continues to move, guiding the box cover downward through the closing guide rod and pressing the tongue against the guide plate position and stopping. The tongue pressing plate squeezes the tongue on the guide plate and bends it. Then the box conveyor belt continues to move, allowing the bent tongue to move to the fixed tongue plate position and stop. At this time, the packaging box is in the ready-to-close state on the fixed tongue plate. Step 3: The lid adjustment assembly swings through the swing arm assembly and moves into the interlocking gap between the lid and the tongue on the fixed tongue plate. Then, the lid closing plate moves towards the lid, causing the lid to be pressed into the packaging box. The lid adjustment assembly moves synchronously with the lid closing plate. The tongue is pressed against the fixed tongue plate by the sliding pressure plate and moves. The lid adjustment assembly presses the tongue into the packaging box. Step four: After the tongue enters the packaging box, the push-pull component drives the translation pressure plate to be pulled outward. Under the guidance of the guide groove, the pressure hook plate unfolds and causes the rocker cover to swing outward, so that the interlocking seam and the interlocking protrusion of the rocker cover are engaged. After reaching the desired position, the pressure hook plate swings back to horizontal and is pulled out from the interlocking seam. At this time, the closing plate continues to abut against the box cover until the pressure hook plate is pulled out and the closing plate retracts to its original position. After the closing is completed, the box conveyor belt continues to move and sends the packaging box containing ointment into the repressing discharge conveyor belt to flatten both sides of the packaging box again.
