It is suitable for multiple specifications and small batch orders. The overall machine cost is lower, the space is smaller, and the operation threshold is low, making it suitable for small and medium-sized packaging plants. In the existing technology, semi-automatic bottom-attaching equipment has certain drawbacks. Semi-automatic bottom-attaching equipment requires manual repeated placement of paper bags and bottom paper. The manual operation force and speed are inconsistent. Relying solely on visual alignment, the bottom of the bag and bottom paper are prone to skew and misalignment, resulting in unbalanced force at the bottom, easy breakage under load, and poor batch consistency. Summary of the Invention

[0003] The purpose of this invention is to provide a semi-automatic bottom-attaching device and its usage method to solve the problems mentioned in the background art: the semi-automatic bottom-attaching device requires manual repeated placement of paper bags and bottom paper, the manual operation force and speed are inconsistent, the alignment is only by visual inspection, the bottom of the bag and bottom paper are easy to be crooked and misaligned, the bottom is unbalanced, the load is easy to break, and the batch consistency is poor.

[0004] The objective of this invention can be achieved through the following technical solutions: A semi-automatic bottom-applying device includes an adhesive application module, a conveyor module, a linear bearing guide rail, a suction cup assembly, a linear motor, and a compaction and drying module.

The magnetic pole names of the first and second magnetic blocks are the same. The first and second magnetic blocks repel each other to lift the packaging paper bag upwards. A movable suction cup assembly is used to adhere the adhesive-coated bottom-applying cardboard to the bottom of the packaging paper bag at a specific position.

[0005] As a preferred embodiment of the present invention, the storage box is provided with two vertically arranged guide rods inside, which are located on both sides of the storage box. Guide holes are provided on both sides of the lifting plate, and the guide rods are slidably connected to the guide holes of the lifting plate, so that the lifting plate moves up and down in the vertical direction.

[0006] As a preferred embodiment of the present invention, the cross-sectional shape of the lifting plate is the same as that of the storage box, the lifting plate is slidably connected to the inner wall of the storage box, the lifting plate is fixed to the second magnetic block, the first magnetic block is fixed to the inner bottom of the storage box, and the position of the first magnetic block is aligned with the position of the second magnetic block.

[0007] As a preferred technical solution of the present invention, a transfer chamber and a discharge port are provided on the top side of the storage box. The transfer chamber is connected to the interior of the storage box, and the discharge port is opened at the top of one side of the storage box. The transfer chamber is used to transfer one of the packaging paper bags, and the discharge port is used to transport the pasted bottom cardboard and the packaging paper bag. The compaction and drying module is located on one side of the discharge port.

[0008] As a preferred technical solution of the present invention, the inner wall of the storage box is provided with a guide cavity. The horizontal cross-section of the guide cavity is defined by the same shape as the packaging paper bag. The guide cavity is used to raise and lower the position of the stacked packaging paper bags. The vertical cross-section edge of the guide cavity is in the shape of a "7". The top of the guide cavity is used to send the packaging paper bag into the material conveying structure.

[0009] As a preferred embodiment of the present invention, the material conveying structure includes a third roller and a fourth roller. A gear set consisting of two meshing spur gears is installed at the same end of the third roller and the fourth roller. The rotation direction of the third roller is opposite to that of the fourth roller. The gap between the third roller and the fourth roller is used to convey the uppermost packaging paper bag to a specific position.

[0010] As a preferred embodiment of the present invention, the ends of the third roller shaft, the second roller shaft, and the first roller shaft are all provided with a synchronous pulley group consisting of a plurality of synchronous pulleys. A synchronous belt is provided between each synchronous pulley of the synchronous pulley group. A drive motor is provided at the end of the first roller shaft. The drive motor is used to drive the first roller shaft, the second roller shaft, and the third roller shaft to rotate synchronously and intermittently.

[0011] As a preferred embodiment of the present invention, the rotation directions of the first roller shaft, the second roller shaft, and the third roller shaft are the same as the direction of conveying the packaging paper bags, and the two ends of the first roller shaft, the two ends of the second roller shaft, the two ends of the third roller shaft, and the two ends of the third roller shaft are all rotatably connected to the top of the storage box.

[0012] A semi-automatic bottom-applying method, using the aforementioned semi-automatic bottom-applying device, includes the following steps: S1. Place the un-adhesive bottom cardboard into the glue application module, feed the bottom cardboard between the two paper feeding traction rollers, and apply glue and press the bottom cardboard with the glue application roller and rubber pressure roller to apply a uniform layer of glue to the surface of the bottom cardboard. S2. Use the suction cup assembly to pick up the adhesive-coated cardboard. The coated cardboard enters the surface of the conveyor module. The suction cup assembly picks up the cardboard on the surface of the conveyor module and moves the suction cup assembly along the linear bearing guide rail. S3. The linear motor moves the suction cup assembly directly above the adhesive assembly. The suction cup assembly moves along the linear bearing guide rail until the linear motor is positioned in the transfer cavity. S4. The pasting component pastes the bottom cardboard to the bottom of the packaging paper bag. After the packaging paper bag is lifted by the lifting plate, it is transported to the transfer chamber through the material conveying structure. The descending suction cup component pastes the bottom cardboard to the bottom of the packaging paper bag. S5. The compaction and drying module is used to compact the bottom cardboard pasted on the packaging paper bag. The packaging paper bag discharged from the outlet is sent into the compaction and drying module, and the packaging paper bag is conveyed and compacted at the same time by multiple pairs of pressure rollers.

[0013] As a preferred technical solution of the present invention, the conveyor module in S2 has a partition on the surface of the conveyor belt for supporting the bottom cardboard. The partitions are arranged at equal intervals around the surface of the conveyor belt to avoid contact between the bottom cardboard and the surface of the conveyor belt. In S5, several of the pressure rollers are heatable steel rollers to ensure that the glue on the bottom cardboard is leveled and dried with the packaging paper bag.

[0014] Compared with the prior art, the beneficial effects of the present invention are: Equipped with a material storage structure, the packaging paper bags are lifted to the top of the storage box by the mutual repulsion of the first and second magnetic blocks, thereby realizing the automatic feeding function and improving production efficiency. When the suction cup assembly comes into contact with the transfer cavity, it can attach the bottom cardboard to the bottom of the packaging paper bag. The guide cavity is used to guide the stacked packaging paper bags, so that the packaging paper bags can smoothly enter the gap between the third and fourth roller shafts. Equipped with a material conveying structure, the first and second rollers can limit the uppermost layer of packaging paper bags, and the third and fourth rollers drive each other to convey the packaging paper bags to a specific position inside the guide cavity at a specific frequency. The adhesive component automatically attaches the bottom cardboard to the bottom of the packaging bag, ensuring a smooth and secure bond and reducing manual operation. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0020] Example 1:

[0021] Please see Figure 1 - Figure 3As shown, a semi-automatic bottom-applying device includes an adhesive application module 1, a conveyor module 2, a linear bearing guide rail 3, a suction cup assembly 4, a linear motor 6, and a compaction and drying module 7. The linear motor 6 reciprocates along the linear bearing guide rail 3, feeding the bottom-applying cardboard into the adhesive application module 1, whereby the adhesive application module 1 applies adhesive to the bottom-applying cardboard, creating a layer of adhesive on its surface. The bottom-applying cardboard then enters the surface of the conveyor module 2, where the suction cup assembly 4 adheres to the surface of the conveyor module 2. The linear motor 6 rotates the suction cup assembly 4 along the linear bearing guide rail 3. The suction cup assembly 4 of machine 6 moves directly above the adhesive assembly 5, allowing the bottom cardboard to be adhered to the packaging paper bag. After the bottom cardboard is adhered to the bottom of the packaging paper bag, it can enter the compaction device. The compaction device conveys and compacts the packaging paper bag with the bottom cardboard attached. The adhesive assembly 5 is located below one end of the linear bearing guide rail 3 and on one side of the conveyor module 2. The adhesive assembly 5 includes a material storage structure 510 for lifting the packaging paper bag and a material conveying structure 520 for conveying the packaging paper bag. The material storage structure 510 includes a section located directly below the linear bearing guide rail 3. The storage box 511 is located on one side of the conveyor module 2. The reciprocating motion of the suction cup assembly 4 causes it to fall onto the top of the storage box 511. The storage box 511 contains a lifting plate 512, a first magnetic block 514, and a second magnetic block 515. The lifting plate 512 is located above the second magnetic block 515. The first magnetic block 514 is located at the bottom of the storage box 511. The second magnetic block 515 is fixed to the lower surface of the lifting plate 512, and the first magnetic block 514 is fixed to the bottom of the storage box 511. The magnetic poles of the first magnetic block 514 and the magnetic poles of the second magnetic block 515 are specified. With the same pole name, the first magnetic block 514 and the second magnetic block 515 repel each other to lift the packaging paper bag upwards. The movable suction cup assembly 4 is used to stick the adhesive-coated bottom cardboard to the bottom of the packaging paper bag at a specific position. The packaging paper bags are stacked on the upper surface of the lifting plate 512 in advance. Under the action of magnetism, the first magnetic block 514 and the second magnetic block 515 move away from each other, thereby lifting the packaging paper bags arranged on the surface of the lifting plate 512 upwards. The top layer of packaging paper bags comes into contact with the first roller shaft 522 and the second roller shaft 523. Under the action of the material conveying structure 520, the top layer of bottom cardboard is conveyed.

[0022] Please see Figure 3 - Figure 5As shown, the storage box 511 has two vertically arranged guide rods 513 inside. The two guide rods 513 are located on both sides of the inside of the storage box 511. The lifting plate 512 is raised and lowered by the guide rods 513, so that the lifting plate 512 lifts the bottom cardboard upward along the guide rods 513. Guide holes are opened on both sides of the lifting plate 512. The guide rods 513 are slidably connected to the guide holes of the lifting plate 512. The lifting plate 512 rises and falls in the vertical direction. The first magnetic block 514 and the second magnetic block 515 move away from each other, thereby pushing the bottom cardboard to the top of the storage box 511.

[0023] Please see Figure 3 - Figure 5 As shown, the cross-sectional shape of the lifting plate 512 is the same as that of the storage box 511. The lifting plate 512 is slidably connected to the inner wall of the storage box 511. The lifting plate 512 is fixed to the second magnetic block 515. The first magnetic block 514 is fixed to the bottom of the storage box 511. The position of the first magnetic block 514 is aligned with the position of the second magnetic block 515. The lifting plate 512 moves up and down synchronously with the second magnetic block 515. The first magnetic block 514 is fixed to the storage box 511, so that the first magnetic block 514 drives the second magnetic block 515 and the lifting plate 512 to move up and down synchronously.

[0024] Please see Figure 3 - Figure 5 As shown, the top side of the storage box 511 is provided with a transfer cavity 516 and a discharge port 517. The transfer cavity 516 is connected to the interior of the storage box 511. The packaging paper bag at the top is fed into the interior of the transfer cavity 516. Inside the transfer cavity 516, the bottom cardboard of the suction cup assembly 4 can be attached to the inside of the packaging paper bag. The discharge port 517 is opened at the top of one side of the storage box 511. The transfer cavity 516 is used to transfer one of the packaging paper bags. The discharge port 517 is used to transport the attached bottom cardboard and the packaging paper bag. The compaction and drying module 7 is located on one side of the discharge port 517. When the suction cup assembly 4 descends, it can press the bottom cardboard on the lower surface of the suction cup assembly 4 down to the bottom of the packaging paper bag.

[0025] Please see Figure 3 - Figure 5 As shown, the inner wall of the storage box 511 is provided with a guide cavity 518. The horizontal cross-section of the guide cavity 518 is defined by the same shape as the packaging paper bag. The guide cavity 518 is used to raise and lower the position of the stacked packaging paper bags. The vertical cross-section edge of the guide cavity 518 is shaped like a "7". The top of the guide cavity 518 is used to send the packaging paper bag into the conveying structure 520. The lifting plate 512 can lift the stacked packaging paper bags. When the packaging paper bags move along the direction of the guide cavity 518, they will move back and forth slightly horizontally.

[0026] It should be noted that the backing cardboard is conveyed along the inside of the gluing module 1, allowing a layer of glue to be applied to its surface. The backing cardboard enters the surface of the conveyor module 2 from the gluing module 1. Because the surface of the conveyor module 2 is equipped with several thin support strips, the backing cardboard is prevented from contacting and sticking to the conveyor belt of the conveyor module 2. The suction cup assembly 4 uses a cylinder to lower the suction cup and adsorb the backing cardboard. The linear motor 6 drives the suction cup assembly 4 to move along the linear bearing guide rail 3 until it reaches the top of the pasting assembly 5. When the pasting component 5 is in operation, the first magnetic block 514 and the second magnetic block 515 repel each other, so that the lifting plate 512 moves up and down along the guide rod 513. The lifting plate 512 lifts the packaging paper bag to the top, and the uppermost packaging paper bag comes into contact with the conveying structure 520. The conveying structure 520 sends the top packaging paper bag into the transfer chamber 516. The packaging paper bag in the transfer chamber 516 is attached to the bottom cardboard. The third roller shaft 524 and the fourth roller shaft 525 continue to rotate, so that the packaging paper bag is discharged from the discharge port 517.

[0027] Please see Figure 2 , Figure 5 and Figure 6 As shown, the conveying structure 520 includes a third roller 524 and a fourth roller 525. A gear set 528 consisting of two meshing spur gears is installed at the same end of both rollers 524 and 525. The rotation direction of the third roller 524 is opposite to that of the fourth roller 525. The gap between the third roller 524 and the fourth roller 525 is used to convey the uppermost packaging paper bag to a specific position. The lifting plate 512 lifts the packaging paper bag upwards, bringing the uppermost packaging paper bag into contact with the first roller 522 and the second roller 523, preventing the packaging paper bag from falling out of the storage box 511. When the top layer of packaging paper bags is discharged, the drive motor 521 drives the first roller shaft 522, the second roller shaft 523 and the third roller shaft 524 to rotate, conveying the top layer of packaging paper bags to the discharge port 517. When the top layer of packaging paper bags reaches a specific position, the drive motor 521 stops rotating. At this time, the suction cup assembly 4 descends, so that the bottom cardboard below the suction cup is attached to the bottom of the packaging paper bag, ensuring that the bottom cardboard is attached to the packaging paper bag. After completion, the drive motor 521 drives the third roller shaft 524 and the fourth roller shaft 525 to continue rotating, thereby discharging the attached packaging paper bags from the discharge port 517.

[0028] Please see Figure 5 and Figure 6As shown, the ends of the third roller shaft 524, the second roller shaft 523, and the first roller shaft 522 are all provided with a synchronous pulley group 526 composed of several synchronous pulleys. A synchronous belt 527 is provided between each synchronous pulley of the synchronous pulley group 526. A drive motor 521 is provided at the end of the first roller shaft 522. The drive motor 521 is used to drive the first roller shaft 522, the second roller shaft 523, and the third roller shaft 524 to rotate synchronously and intermittently.

[0029] Please see Figure 5 and Figure 6 As shown, the rotation directions of the first roller 522, the second roller 523, and the third roller 524 are the same as the direction of conveying the packaging paper bags. Both ends of the first roller 522, the second roller 523, and the third roller 524 are rotatably connected to the top of the storage box 511. The drive motor 521 drives the synchronous wheel set 526 at the ends of the first roller 522, the second roller 523, and the third roller 524 to rotate, so that the first roller 522, the second roller 523, and the third roller 524 rotate in the same direction, which can drive the top packaging paper bag to move. The third roller 524 and the fourth roller 525 can send the top packaging paper bag into the discharge port 517. After the pasting is completed, the packaging paper bag can be discharged from the discharge port 517.

[0030] It should be noted that the rotation of the drive motor 521 drives the end of the first roller shaft 522 to work, and the synchronous pulley set 526 and synchronous belt 527 at the ends of the second roller shaft 523 and the third roller shaft 524 to work. As a result, the stacked packaging paper bags are lifted by the lifting plate 512, so that the first roller shaft 522, the second roller shaft 523 and the third roller shaft 524 can transport the top layer of packaging paper bags. And through the rotation of the third roller shaft 524 and the fourth roller shaft 525, the packaging paper bags are discharged from the gap between the third roller shaft 524 and the fourth roller shaft 525. After the packaging paper bags and the bottom cardboard are glued together, they are discharged from the discharge port 517.

[0031] Please see Figure 7 As shown, a semi-automatic bottom-applying method, using the aforementioned semi-automatic bottom-applying device, includes the following steps: S1. Place the un-adhesive bottom cardboard into the glue coating module 1. Feed the bottom cardboard between two paper feeding traction rollers. Apply glue and press the bottom cardboard with the glue roller and rubber pressure roller to apply a uniform layer of glue to the surface of the bottom cardboard. Use the two closely spaced paper feeding traction rollers to feed the bottom cardboard between the glue roller and the rubber pressure roller so that the glue on the glue roller comes into contact with the bottom cardboard and applies a portion of glue to the bottom cardboard. Then the cardboard continues to move forward into the inside of the conveyor module 2. S2. The adhesive-coated backing cardboard is adsorbed using the suction cup assembly 4. The coated backing cardboard enters the surface of the conveyor module 2. The conveyor module 2 has partitions on the surface of the conveyor belt to support the backing cardboard. The partitions are evenly spaced around the surface of the conveyor belt to prevent the backing cardboard from contacting the surface of the conveyor belt. The suction cup assembly 4 adsorbs the backing cardboard on the surface of the conveyor module 2. The suction cup assembly 4 is moved along the linear bearing guide rail 3. Since the conveyor belt surface of the conveyor module 2 has a ring of supporting thin plates, the backing cardboard will not contact the surface of the conveyor belt. The suction cup assembly 4 adsorbs the backing cardboard. S3, the linear motor 6 moves the suction cup assembly 4 directly above the adhesive assembly 5. The suction cup assembly 4 moves along the linear bearing guide rail 3 until the linear motor 6 is located at the transfer cavity 516. The suction cup assembly 4 delivers the adhesive-coated bottom cardboard to the adhesive assembly 5, and then places the bottom cardboard on the top of the adhesive assembly 5. S4. The pasting component 5 pastes the bottom cardboard to the bottom of the packaging paper bag. After the packaging paper bag is lifted by the lifting plate 512, it is transported to the transfer chamber 516 through the material conveying structure 520. The descending suction cup component 4 pastes the bottom cardboard to the bottom of the packaging paper bag. After the lifting plate 512 lifts the packaging paper bag, the bottom cardboard is pasted to the bottom of the packaging paper bag. Then the packaging paper bag and the bottom cardboard come into contact, thereby sticking the bottom cardboard and the packaging paper bag together. S5. The bottom cardboard pasted on the packaging paper bag is compacted using the compaction and drying module 7. The packaging paper bag discharged from the outlet 517 is sent into the compaction and drying module 7. The packaging paper bag is conveyed and compacted at the same time by multiple pairs of pressure rollers. Some of the pressure rollers are heated steel rollers to ensure that the glue on the bottom cardboard is level and dried with the packaging paper bag. The initially pasted packaging paper bag and bottom cardboard are sent between multiple pairs of pressure rollers. The packaging paper bag is conveyed and compacted at the same time by the pressure rollers. Some of the pressure rollers are heated steel rollers, so that the glue is compacted and dried at the same time, so that the packaging paper bag and bottom cardboard are fully pasted together.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
