Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a ribbon box pasting mechanism, a packaging box ribbon machine and a ribbon box pasting method. Background Art

[0002] During the production process of ribbon packaging boxes, due to the soft nature of the ribbon, it is often necessary to manually attach the ribbon to the designated position of the packaging box. The current production process usually includes two consecutive stations: a dispensing station and a shaping station. At the dispensing station, the packaging box is dispensed with glue, and the dispensing position will be distributed along the inner or outer wall of the packaging box where the ribbon needs to be attached. After the dispensing is completed, the shaping process can be entered. At the shaping station, the operator first fixes the packaging box, holds the free end of the ribbon with one hand, and holds the scraper with the other hand to scrape and press along the upper surface of the ribbon. This operation starts from the top of the first side wall of the packaging box, slides along the side wall to the bottom, and then scrapes along the bottom surface to the bottom of the second side wall opposite to the first side wall, and finally scrapes upward to the top of the second side wall. The entire process relies on the operator's manual skills and experience, so not only is the production efficiency low, but it also has a certain impact on the quality of the final product.

[0003] This manual operation method has many limitations. It is time-consuming and may lead to uneven product quality. There is an urgent need to find a more efficient and stable solution to improve production efficiency and product consistency. Summary of the invention

[0004] In view of this, the present invention proposes a ribbon box pasting mechanism, a packaging box ribbon machine and a ribbon box pasting method, through the provided connecting head, the lower pressing block can be driven to move toward the packaging box, so that the lower pressing block can contact the ribbon on the packaging box, and the ribbon can be tightly attached to the bottom of the inner wall of the packaging box, and after the lower pressing block contacts the packaging box, the connecting head continues to move downward, and the movable gap becomes smaller at this time, and the linkage part will contact the side pressure part through the transmission surface, and push the side pressure part toward the side away from the lower pressing block, and the side pressure part makes the ribbon completely attached to the bottom of the inner wall of the packaging box during the movement, and when the side pressure part contacts the side of the inner wall of the packaging box, the ribbon is attached to the inner side wall of the packaging box, thereby realizing one-time pressing to complete the ribbon pasting operation, and making the ribbon stick to the inner wall of the packaging box during the pasting process, so as to improve the ribbon shaping and pasting efficiency, and at the same time, make the product have better consistency.

[0026] On the basis of the above technical solution, preferably, it also includes a drying mechanism, which is arranged between the glue dispensing mechanism and the ribbon box sticking mechanism, and is used to dry the glue on the packaging box.

[0027] On the other hand, the present invention provides a method for pasting a box with a ribbon, which is implemented based on the above-mentioned ribbon pasting box mechanism and includes the following steps:

[0028] The S1 transverse movement module drives the primary negative pressure adsorption component to move to the outside of the fixed end of the ribbon, and through suction, the free end of the ribbon enters the primary negative pressure adsorption component;

[0029] The S2 transverse movement module moves along the width direction of the packaging box, so that part of the ribbon leaves the primary negative pressure adsorption component and is located below the secondary negative pressure adsorption component;

[0030] S3 The secondary negative pressure adsorption component causes the free end of the ribbon to leave the primary negative pressure adsorption component through suction and enter the secondary negative pressure adsorption component;

[0031] The S4 correction part squeezes the free end of the ribbon, and the lateral movement module moves along the width direction of the packaging box to straighten the ribbon and pull the free end to the outside of the packaging box;

[0032] The S5 transverse movement module pushes the connector downward until the box pasting action is completed through the downward pressure block and the side pressure piece.

[0033] The ribbon box pasting mechanism, packaging box ribbon machine and ribbon box pasting method of the present invention have the following beneficial effects compared with the prior art:

[0034] (1) By setting a connecting head, the lower pressing block can be driven to move toward the packaging box, so that the lower pressing block can contact the ribbon on the packaging box and make the ribbon close to the bottom of the inner wall of the packaging box. After the lower pressing block contacts the packaging box, the connecting head continues to move downward. At this time, the movable gap becomes smaller, and the linkage part will contact the side pressing part through the transmission surface and push the side pressing part toward the side away from the lower pressing block. The side pressing part makes the ribbon completely fit to the bottom of the inner wall of the packaging box during the movement, and when the side pressing part contacts the side of the inner wall of the packaging box, the ribbon is fitted to the inner wall of the packaging box, thereby achieving one-time downward pressure to complete the ribbon bonding operation, and making the ribbon fit to the inner wall of the packaging box during the bonding process, so as to improve the ribbon shaping and bonding efficiency, and at the same time, make the product have better consistency;

[0035] (2) The suction end of the pulling component is set to absorb the ribbon and straighten the ribbon. The pulling component is then driven by the transverse movement module to move so that the ribbon is straightened and extended to the outside of the packaging box. At this time, the connecting head is pressed down, and the ribbon is attached and fixed by the pressing block and the side pressure piece, so that the shaping and box-attaching process of the ribbon does not require manual operation, and a mechanized automatic processing operation can be realized;

[0036] (3) By setting the dispensing head tilted, the dispensing head can form an angle with the inner wall and the inner bottom of the packaging box, so as to perform the dispensing operation, while avoiding being perpendicular to the bottom of the packaging box and being unable to dispense glue on the side wall. The dispensing head is preferably tilted at a 45° angle relative to the bottom of the packaging box. This setting is based on the fact that the end of the dispensing head is conical. After the dispensing head is tilted, the dispensing operation can still be performed. For the inner walls with different directions on both sides, the dispensing head can be directly driven by the rotary drive unit to rotate 180 degrees, so as to perform dispensing on different inner walls or outer walls, so as to be suitable for dispensing operations at different dispensing positions.

[0046] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0047] During the production process of ribbon packaging boxes, due to the soft nature of the ribbon, it is often necessary to manually attach the ribbon to the designated position of the packaging box. The current production process usually includes two consecutive stations: a dispensing station and a shaping station. At the dispensing station, the packaging box is dispensed with glue, and the dispensing position will be distributed along the inner or outer wall of the packaging box where the ribbon needs to be attached. After the dispensing is completed, the shaping process can be entered. At the shaping station, the operator first fixes the packaging box, holds the free end of the ribbon with one hand, and holds the scraper with the other hand to scrape and press along the upper surface of the ribbon. This operation starts from the top of the first side wall of the packaging box, slides along the side wall to the bottom, and then scrapes along the bottom surface to the bottom of the second side wall opposite to the first side wall, and finally scrapes upward to the top of the second side wall. The entire process relies on the operator's manual skills and experience, so not only is the production efficiency low, but it also has a certain impact on the quality of the final product.

[0048] In order to solve the problem, the present invention proposes a ribbon box sticking mechanism. In a specific packaging box example, the packaging box is a rectangular parallelepiped with an open side. One end of the ribbon is fixed at the connection between the side wall and the bottom wall of the packaging box. Now, the ribbon needs to be stuck to the packaging box along the width direction of the packaging box and extend to the outside of the packaging box. In addition, the packaging box is on the ribbon.

[0049] like Figure 1-3As shown, the ribbon box sticking mechanism of the present invention is used to stick the ribbon of a packaging box into a box, and includes a connecting head 1, a lower pressing block 2, a side pressing piece 3 and a linkage piece 4.

[0050] The connector 1 is used to connect other parts of the ribbon laminating mechanism and enable the lower pressing block 2 to move relatively. Specifically, a square metal block can be selected and multiple installation positions are set on it to install and connect other parts.

[0051] The lower pressing block 2 is arranged on the connector 1, and there is a movable gap between the lower pressing block 2 and the connector 1. The lower pressing block 2 can move toward and away from the connector 1 through the movable gap. The lower pressing block 2 is used to press the ribbon to the bottom of the inner wall of the packaging box. The lower pressing block 2 is movably connected to the connector 1, and the lower pressing block 2 and the connector 1 are located on the same straight line perpendicular to the packaging box. When the connector 1 moves toward the packaging box, the lower pressing block 2 will move synchronously, and after the lower pressing block 2 contacts the packaging box, the connector 1 continues to move downward, so that the movable gap becomes smaller. The lower pressing block 2 is arranged in an H shape as a whole, and the middle part is used to squeeze the ribbon to fit the bottom of the inner wall of the packaging box, and the two ends are used to install two side pressure pieces 3 respectively.

[0052] The side pressure pieces 3 are two in number and are movably arranged on both sides of the lower pressure block 2. The two side pressure pieces 3 can move along the same straight line. The side pressure pieces 3 are used to press the ribbon against the inner wall of the packaging box. The side pressure pieces 3 can move on both sides of the lower pressure block 2, and the bottom surfaces of the side pressure pieces 3 and the bottom surfaces of the lower pressure block 2 are located on the same plane, which coincides with the plane where the bottom of the inner wall of the packaging box is located when the ribbon is pasted, so that the side pressure pieces 3 can also squeeze the ribbon against the bottom of the inner wall of the packaging box. When the side pressure pieces 3 move away from the lower pressure block 2, the ribbon can be squeezed to fit the inner wall of the packaging box. The side pressure pieces 3 are rectangular as a whole. In the present embodiment, since one end of the ribbon is fixed inside the packaging box and the other end needs to extend outside the packaging box, the ribbon can be pressed against one side wall of the packaging box by one of the two side pressure pieces 3. However, the two side pressure pieces 3 can also be used in scenarios where the ribbon needs to be attached to the two side walls of the packaging box.

[0053] There are two linkage parts 4, and both are fixed on the connecting head 1. A transmission surface is provided on the linkage part 4. The transmission surface forms an angle with the straight line along which the side pressure part 3 moves. When the activity gap becomes smaller, the transmission surface contacts and pushes the side pressure part 3 away from the lower pressure block 2. Specifically, the two linkage parts 4 are symmetrically arranged on both sides of the connecting head 1. When the lower pressure block 2 contacts the packaging box and the connecting head 1 continues to move toward the packaging box, the side pressure part 3 can be pushed by the linkage part 4 to move along the bottom of the inner wall of the packaging box toward the inner wall of the packaging box until the ribbon is pressed against the inner wall of the packaging box.

[0054] During the downward pressing process of the connecting head 1, the transmission surface will leave the side pressure piece 3, that is, at the maximum pushing stroke of the transmission surface. At this time, the distance between the two opposite surfaces of the two side pressure pieces 3 must be equal to the width of the two inner walls of the packaging box, or slightly larger than the width, so that the ribbon can be stably attached to the inner wall of the packaging box.

[0055] In this embodiment, a transverse moving module 5 and a first pushing member 6 are also provided. The transverse moving module 5 has a transverse moving end. The first pushing member 6 is arranged on the transverse moving end of the transverse moving module 5. The first pushing member 6 has a first movable end. The connecting head 1 is arranged on the first movable end to drive the connecting head 1 to move toward the packaging box. The transverse moving module 5 can be driven to move along the transmission direction of the packaging box, and after moving to the top of the packaging box, the connecting head 1 is pushed down by the first pushing member 6. The transverse moving module 5 can use a linear module, and the first pushing member 6 can use a cylinder. The transverse moving end of the transverse moving module 5 and the first movable end of the first pushing member 6 are perpendicular to each other along the straight line.

[0056] The automatic pressing down action of the connector 1 is realized by the transverse movement module 5 and the first pushing member 6, thereby further improving the processing efficiency.

[0057] Although the rapid lamination of the ribbon can be achieved by setting the lower pressure block 2 and the side pressure piece 3, in the prior art, in addition to the manual lamination of the ribbon, the operator is also required to pull the ribbon. Therefore, in this embodiment, a pulling component 7 is also provided to cooperate with the ribbon box lamination operation. The pulling component 7 is provided on the transverse end of the transverse module 5. The pulling component 7 includes an adsorption end, which is used to absorb the ribbon and pull the ribbon during the movement of the transverse end.

[0058] Before the connector 1 is pressed down, the ribbon is sucked by the adsorption end of the pulling component 7 and straightened, and then the pulling component 7 is driven by the transverse module 5 to move, so that the ribbon is straightened and extended to the outside of the packaging box. At this time, the connector 1 is pressed down again, and the ribbon is fitted and fixed by the pressing block 2 and the side pressure piece 3, so that the ribbon shaping and box pasting process does not require manual operation, and mechanized automatic processing can be realized.

[0059] Specifically, the pulling assembly 7 also includes a second pushing member 72, a primary negative pressure adsorption member 73, a secondary negative pressure adsorption member 74 and a correction part 75. The second pushing member 72 is arranged on the transverse end of the transverse module 5. The second pushing member 72 has a second movable end. The primary negative pressure adsorption member 73 is arranged on the second movable end of the second pushing member 72. The secondary negative pressure adsorption member 74 is arranged on the second movable end of the second pushing member 72 and is located between the primary negative pressure adsorption member 73 and the connecting head 1. The correction part 75 is arranged in the secondary negative pressure adsorption member 74 for contacting and squeezing the ribbon into the secondary negative pressure adsorption member 74.

[0060] The primary negative pressure adsorption member 73 is a cylindrical component, which is arranged on the second movable end through a mounting frame. A slot is provided on the mounting frame for connecting the second movable end. The relative distance between the primary negative pressure adsorption member 73 and the secondary negative pressure adsorption member 74 can be adjusted through the slot, so as to adapt to ribbons of different lengths for adsorption operation. The secondary negative pressure adsorption member 74 includes an air guide cylinder and an adsorption block. The adsorption block is provided with a suction port, and the correction part 75 is movably arranged in the suction port. The air guide cylinder is fixed on the adsorption block and connected to the suction port. The inner diameter of the suction port is smaller than the inner diameter of the primary negative pressure adsorption member 73. The primary negative pressure adsorption member 73 is used to move with the transverse movement module 5 and is pushed toward the packaging by the second pushing member 72. The box moves, and the ribbon is preliminarily sucked from one end of the packaging box where the ribbon is connected. After suction, the second pushing member 72 drives the primary negative pressure adsorption member 73 to move upward, and the transverse movement module 5 moves at the same time. After the end of the ribbon moves to the bottom of the secondary negative pressure adsorption member 74, the secondary negative pressure adsorption member 74 sucks the ribbon into the air guide cylinder. The ribbon leaves the primary negative pressure adsorption member 73 at this time, that is, the primary negative pressure adsorption member 73 is used for the preliminary picking up of the ribbon, and the secondary negative pressure adsorption member 74 is used for picking up and positioning the ribbon with higher precision. It should be noted that the suction force of the primary negative pressure adsorption member 73 must be smaller than that of the secondary negative pressure adsorption member 74 to avoid the secondary negative pressure adsorption member 74 being unable to suck the ribbon into it after the primary negative pressure adsorption member 73 picks up the ribbon.

[0061] After the secondary negative pressure adsorption component 74 absorbs the ribbon, the correction part 75 moves in the suction port of the adsorption block, changes the cross-section of the suction port, and slightly squeezes the ribbon. This setting can straighten the ribbon during the lateral movement of the secondary negative pressure adsorption component 74. At the same time, the ribbon will not twist itself when leaving the suction port, thereby realizing the shaping action of the ribbon.

[0062] Specifically, the correction part 75 is a plate-shaped part, which is inserted into the suction port from the outside of the adsorption block, and a cylinder is provided on the outside of the adsorption block to drive the correction part 75 to insert and leave the suction port. When the ribbon is sucked into the secondary negative pressure adsorption part 74, the correction part 75 enters the suction port to squeeze the ribbon, and when the ribbon leaves the port, the correction part 75 leaves the suction port.

[0063] In some processing scenarios, the ribbon also needs to be attached to the outer wall of the packaging box, that is, the free end of the ribbon extending from the packaging box is attached to the outside of the packaging box, and the ribbon cannot be attached to the outer wall of the packaging box only by the lower pressure block 2 and the side pressure piece 3. Therefore, in a preferred embodiment, a side sticking component 8 is also provided, and the side sticking component 8 is provided on the connecting head 1. The side sticking component 8 includes a side sticking piece 81, and the side sticking piece 81 is used to press the end of the ribbon located outside the packaging box to the outer wall of the packaging box.

[0064] The side sticker assembly 8 is provided to move downward along with the connector 1, and the side sticker 81 presses the outer ribbon of the packaging box onto the outer wall of the packaging box, thereby meeting the needs of the processing and production scenario.

[0065] Specifically, the side sticking assembly 8 also includes a side sticking cylinder, which is fixed to the connecting head 1 through a mounting bracket, and the side sticking member 81 is arranged on the output end of the side sticking cylinder. When the ribbon is attached to the inner wall of the packaging box, the side sticking cylinder drives the side sticking member 81 downward, so that the side sticking member 81 squeezes the ribbon downward to make it contact the outer wall of the packaging box. Specifically, the bottom end of the side sticking member 81 is tilted outward, and a U-shaped groove is provided in the tilted portion. When pressed down, the tilted portion of the side sticking member 81 will contact the packaging box and position the outer wall of the packaging box, and the ribbon enters the U-shaped groove and adheres to the outer side of the packaging box as the side sticking member 81 continues to be pressed down.

[0066] In addition, in the present embodiment, an elastic guide portion 9 is further provided. There are multiple elastic guide portions 9 and all are provided on the lower pressing block 2 . The connector 1 and the side pressure piece 3 are both connected to the lower pressing block 2 via the elastic guide portions 9 .

[0067] The elastic guide part 9 includes a guide column and a spring. Two elastic guide parts 9 are arranged between the lower pressing block 2 and the connecting head 1. The guide column of the elastic guide part 9 is fixed on the lower pressing block 2 and passes through the connecting head 1, and is slidably connected with the connecting head 1, thereby realizing the movable guiding of the lower pressing block 2 and the connecting head 1. The spring is sleeved outside the guide column, and the two ends are respectively connected to the lower pressing block 2 for the connecting head 1, so that when the lower pressing block 2 is pressing the ribbon, the spring can produce compression deformation and provide a certain pressure. At the same time, after the lower pressing block 2 leaves the packaging box, the spring pushes the lower pressing block 2 to reset.

[0068] Similar to this arrangement, the side pressure piece 3 and the lower pressure block 2 also adopt a similar arrangement, that is, the guide column is fixed on the side pressure piece 3 and is slidably connected to the lower pressure block 2. A spring is also sleeved on the guide column, but due to space limitations, one end of the spring is set on the lower pressure block 2, and the other end is connected to the end of the guide column. When the spring moves up the connecting head 1, it pushes the guide column to move, so that the reset side pressure piece 3 is reset.

[0069] Although the ribbon box sticking mechanism proposed in this embodiment can realize the fully automatic box sticking operation of the ribbon, for glue dispensing, it is still necessary to position the packaging box by means of a positioning tool, and then use a special lamp to irradiate light onto the packaging box to form glue dispensing points, and then manually dispense glue according to the glue dispensing points. In order to realize the fully automatic ribbon sticking operation of the packaging box, the present invention also proposes a packaging box ribbon machine.

[0070] like Figure 1-8As shown, the packaging box ribbon machine of the present invention includes a transmission line 10, and a loading mechanism 20, a glue dispensing mechanism 30 and the above-mentioned ribbon box sticking mechanism which are sequentially arranged along the conveying direction of the transmission line 10, the loading mechanism 20 is used to transfer the packaging box to the transmission line 10, and the glue dispensing mechanism 30 is used to dispense glue on the packaging box.

[0071] Among them, the transmission line 10 is set on the ground, which includes an equipment frame, conveyor rollers, a conveyor belt and a motor. The transmission rollers are set on the equipment frame, and the conveyor belt is set on the equipment frame through the conveyor rollers to form a whole transmission device. The motor is fixed to the equipment frame, and the output end is connected to the conveyor roller by transmission, thereby forming the transmission line 10. The feeding mechanism 20, the gluing mechanism 30 and the ribbon box pasting mechanism are sequentially arranged on the transmission line 10, which are used for feeding, gluing and ribbon box pasting operations of the packaging box. After the box pasting is completed, the transmission line 10 transmits the packaging box to the next process for processing, thereby realizing full automation in the ribbon box pasting process to improve production efficiency and save manpower.

[0072] In this embodiment, the dispensing mechanism 30 includes a two-axis module 301, a rotary drive unit 302 and a dispensing head 303. The two-axis module 301 is arranged on the outside of the transmission line 10. The two-axis module 301 has a transfer end. The rotary drive unit 302 is arranged on the transfer end of the two-axis module 301. The rotary drive unit 302 has a rotating end. The dispensing head 303 is tiltedly arranged on the transfer end of the two-axis module 301 and is transmission-connected to the rotating end of the rotary drive unit 302.

[0073] Specifically, the dispensing head 303 can be moved horizontally and vertically above the transmission line 10 through the two-axis module 301, so that dispensing operations can be performed on the packaging box along the part where the ribbon needs to be pasted. If it is necessary to dispense glue on the packaging box in places other than the width direction, the two-axis module 301 needs to be replaced with a three-axis module.

[0074] The rotary drive unit 302 can use a servo motor or a stepper motor. Through the tilted setting of the dispensing head 303, the dispensing head 303 can form an angle with the inner wall and the inner bottom of the packaging box, so as to perform the dispensing operation, and avoid being perpendicular to the bottom of the packaging box and being unable to dispense glue on the side wall. The inclination angle of the dispensing head 303 relative to the bottom of the packaging box is preferably 45°. This setting is based on the conical end of the dispensing head 303. After its tilted setting, the dispensing operation can still be performed. For the inner walls with different directions on both sides, the dispensing head 303 can be directly driven by the rotary drive unit 302 to rotate 180 degrees, so as to perform glue dispensing on different inner walls or outer walls.

[0075] It should be noted that an air blowing head needs to be provided on the dispensing head 303 so that during the dispensing process, the air blowing head follows the movement of the dispensing head 303 and blows the ribbon synchronously, so that the ribbon will not be located at the position where the dispensing head 303 needs to dispense glue.

[0076] As a preferred implementation, a drying mechanism 40 is further provided. The drying mechanism 40 is provided between the glue dispensing mechanism 30 and the ribbon box pasting mechanism, and is used for drying the glue on the packaging box.

[0077] After the glue is dispensed, the next station is to paste the ribbon, and the glue just dispensed does not have a good adhesion effect due to its high water content. Therefore, a drying mechanism 40 is set between the glue dispensing mechanism 30 and the ribbon box pasting mechanism, so that before the ribbon box pasting operation is performed on the packaging box, the glue dispensed on the packaging box is dried, so that the glue forms a semi-dry viscous state.

[0078] Specifically, the drying mechanism 40 includes a third pushing member 401 and a blowing block 402. The third pushing member 401 is arranged outside the transmission line 10 and has a third movable end. The blowing block 402 is fixed on the third movable end. At least one air channel is arranged on the blowing block 402. The blowing block 402 is used to blow out gas through the air channel to air-dry the glue on the packaging box.

[0079] In this embodiment, the number of the blowing blocks 402 is set to two. This setting is due to the fact that the ribbon box pasting mechanism operates at a relatively fast speed. In order not to affect the transmission speed of the entire line, two blowing blocks 402 are set to perform blowing and drying operations on both sides so as not to affect the transmission speed of the packaging box. At the same time, it has a better drying effect on the glue liquid. The third pushing member 401 is preferably a cylinder.

[0080] The air channel on the blowing block 402 needs to be set according to the glue dispensing position on the packaging box. For example, if the packaging box needs to be glued on both inner and outer side walls, Figure 8 As shown, the blowing block 402 can be configured to be U-shaped, and air channels can be provided at both ends to perform air drying treatment on the two side walls respectively.

[0081] For the feeding mechanism 20, if Figure 6 As shown, in the present embodiment, it is configured as a linear cylinder, and a lifting cylinder is configured on the output end of the linear cylinder, a rotary cylinder is configured on the lifting cylinder, and a clamping cylinder is configured on the rotary end of the rotary cylinder, and clamping plates are configured on the two rotating ends of the clamping cylinder, and the two clamping plates cooperate to clamp the sides of the packaging box, and the angle of the packaging box is adjusted by the rotary cylinder, and then the linear module drives it to move from outside the transmission line 10 to the transmission line 10.

[0082] In addition, a positioning component should be provided on the transmission line 10. The positioning component is arranged next to the loading mechanism 20. When the packaging box moves onto the transmission line 10, the positioning component pushes the packaging box to the side so that the ribbon pasting position is located on a fixed straight line of the transmission line 10, and subsequent processing operations are carried out during the transmission process.

[0083] In a specific ribbon box pasting action, the ribbon box pasting method of the present invention is implemented based on the above-mentioned ribbon box pasting mechanism, including steps S1-S5.

[0084] Step S1: the transverse movement module 5 drives the primary negative pressure adsorption component 73 to move to the outside of the fixed end of the ribbon, and causes the free end of the ribbon to enter the primary negative pressure adsorption component 73 through suction.

[0085] The primary negative pressure adsorption member 73 is a cylindrical component, which is arranged on the second movable end through a mounting frame. A slot is provided on the mounting frame for connecting the second movable end. The relative distance between the primary negative pressure adsorption member 73 and the secondary negative pressure adsorption member 74 can be adjusted through the slot, so as to adapt to ribbons of different lengths for adsorption operation. The secondary negative pressure adsorption member 74 includes an air guide cylinder and an adsorption block. The adsorption block is provided with a suction port, and the correction part 75 is movably arranged in the suction port. The air guide cylinder is fixed on the adsorption block and connected to the suction port. The inner diameter of the suction port is smaller than the inner diameter of the primary negative pressure adsorption member 73. The primary negative pressure adsorption member 73 is used to move with the transverse movement module 5 and is moved toward the packaging box by the second pushing member 72. The ribbon is preliminarily absorbed from one end of the ribbon connected to the packaging box. After absorption, the second pushing member 72 drives the primary negative pressure adsorption member 73 to move upward.

[0086] Step S2: the transverse movement module 5 moves along the width direction of the packaging box, so that part of the ribbon leaves the primary negative pressure adsorption component 73 and is located below the secondary negative pressure adsorption component 74 .

[0087] After the primary negative pressure adsorption component 73 moves upward to its position, the transverse movement module 5 drives the primary negative pressure adsorption component 73 to move transversely until the free end of the ribbon moves to the bottom of the secondary negative pressure adsorption component 74 .

[0088] Step S3: The secondary negative pressure adsorption component 74 causes the free end of the ribbon to leave the primary negative pressure adsorption component 73 and enter the secondary negative pressure adsorption component 74 through suction.

[0089] At this time, the secondary negative pressure adsorption component 74 sucks the ribbon into the air guide cylinder, and the ribbon leaves the primary negative pressure adsorption component 73, that is, the primary negative pressure adsorption component 73 is used for the preliminary picking up of the ribbon, and the secondary negative pressure adsorption component 74 is used for picking up and positioning the ribbon with higher precision. It should be noted that the suction force of the primary negative pressure adsorption component 73 must be smaller than that of the secondary negative pressure adsorption component 74 to avoid the secondary negative pressure adsorption component 74 being unable to suck the ribbon into its interior after the primary negative pressure adsorption component 73 picks up the ribbon.

[0090] Step S4: the correction part 75 squeezes the free end of the ribbon, and the transverse movement module 5 moves along the width direction of the packaging box to straighten the ribbon and pull the free end to the outside of the packaging box.

[0091] After the secondary negative pressure adsorption component 74 absorbs the ribbon, the correction part 75 moves in the suction port of the adsorption block, changes the cross-section of the suction port, and slightly squeezes the ribbon. This setting can straighten the ribbon during the lateral movement of the secondary negative pressure adsorption component 74. At the same time, the ribbon will not twist itself when leaving the suction port, thereby realizing the shaping action of the ribbon.

[0092] Specifically, the correction part 75 is a plate-shaped part, which is inserted into the suction port from the outside of the adsorption block, and a cylinder is provided on the outside of the adsorption block to drive the correction part 75 to insert and leave the suction port. When the ribbon is sucked into the secondary negative pressure adsorption part 74, the correction part 75 enters the suction port to squeeze the ribbon, and when the ribbon leaves the port, the correction part 75 leaves the suction port.

[0093] Step S5: the lateral movement module 5 pushes the connector downward until the box pasting action is completed through the lower pressing block 2 and the side pressing member 3.

[0094] When the connector 1 moves toward the packaging box, the lower pressure block 2 will move synchronously, and after the lower pressure block 2 contacts the packaging box, the connector 1 continues to move downward, so that the movable gap becomes smaller, and the linkage part 4 can push the side pressure part 3 to move along the bottom of the inner wall of the packaging box toward the inner wall of the packaging box until the ribbon is pressed against the inner wall of the packaging box.

[0095] For the whole machine, after the ribbon box pasting is completed, the conveyor line 10 transfers the packaging box and replaces the packaging box that needs to be pasted with a ribbon, thereby realizing a cyclic box pasting operation.

[0096] 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, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
