[0073] In another embodiment of the utility model, the feeding mechanism 2 includes a feeding assembly 210 and a feeding barrel 220. The feeding assembly 210 is arranged on the frame 1 for conveying products. The feeding barrel 220 is arranged on the frame 1 and is located at the output port of the feeding assembly 210.

It can be understood that the number of products to be packaged is manually confirmed first, and then all the products are placed in the feed shell 211. Since the feed port and the feed belt 213 are located at the same position, when the products are placed in the feed shell 211, they will automatically flow into the feed belt 213, and the feed plate 214 on the feed belt 213 can drive the products on the feed belt 213 to move upward, so that the products can smoothly reach the position of the feed barrel 220; the feed barrel 220 is in a bent tubular shape, with an inlet at one end, which is aligned with the end of the feed belt 213, and an outlet at the other end, which is aligned with the feed port of the feed barrel 220, so as to ensure that the products can be fed into the feed barrel 220 through the feed assembly 210, and the products are automatically placed.

[0076] In a preferred embodiment of the present invention, Figure 3 As shown, a feeding sensor 215 for sensing the product is provided on the feeding belt 213 , and the feeding sensor 215 is electrically connected to the control system 3 .

[0077] When implementing it, Figure 3As shown, the feeding sensor 215 is any one of a photoelectric sensor, a weight sensor, an image sensor, and an infrared sensor. The feeding machine 212 is triggered by the feeding sensor 215, and the feeder 212 triggers the feeding belt 213, so that the product can be automatically fed on the feeder 212, with a higher degree of automation and more convenient and quick to use.

[0079] During the specific implementation, the packaging bag raw material on the forming shell 420 is pulled into the transverse heat sealing component 430 by the film pulling component 440, and then the packaging bag raw material is heat-sealed by the transverse heat sealing component 430 to form the starting bottom edge of the packaging bag. Then the film pulling component 440 continues to pull the film according to the preset film size, and the vertical heat sealing component 450 heat-seals the vertical edge of the film to form a packaging bag with only one opening. Finally, the product is fed into the bag opening of the packaging bag by the feeding component 210. After the feeding is completed, the bag opening of the packaging bag is heat-sealed again by the transverse heat sealing component 430, and then the cutting component 460 cuts off the connected packaging bag raw materials to complete the formation of the packaging bag and the packaging of the product.

[0080] It is worth noting that the film drawing component 440 can continue to draw film from the packaging bag raw material according to the pre-set film drawing length (or color code) and number of times. Each time the film is drawn, the packaging bag is heat-sealed vertically and horizontally once. When the film is drawn to the preset packaging bag size, a packaging bag with a bag opening will be formed waiting for the product to be put into the bag.

[0081] In a preferred embodiment of the present invention, please also refer to Figure 2The packaging bag forming mechanism 4 also includes a vibration component 470, and the vibration component 470 includes a vibration motor and a vibration plate. The vibration motor is arranged on the frame 1, and the vibration plate is arranged on the vibration motor and is located below the forming shell 420. The vibration plate is used to vibrate the packaging bag.

[0082] In specific implementation, Figure 2 As shown, it can be seen from the above that the control system 3 is installed in the control box, the vibration component 470 is composed of a vibration motor and a vibration disk, the vibration motor is installed in the control box, the output shaft of the vibration motor extends out of the control box and is connected to the vibration disk, the vibration disk is a disc-shaped structure, and the position of the vibration disk is exactly at the falling position of the packaging bag. The vibration time and the number of vibrations are set by the control system 3, and the vibration disk vibrates the front and back of the packaging bag to ensure that the product can enter the bag mouth of the packaging bag more accurately.

[0083] In a preferred embodiment of the present invention, please also refer to Figure 2 The packaging bag forming mechanism 4 also includes a material shaking component 480, and the material shaking component 480 includes a telescopic cylinder, a material shaking block and a material blowing component. The telescopic cylinder is arranged on the frame 1; the material shaking block is arranged on the telescopic cylinder and is located below the vibration component 470, and the material shaking block is provided with a material shaking surface inclined downward in the direction of the discharge machine 510 mechanism 5; the material blowing component is arranged on the frame 1, and the blowing direction of the material blowing component is toward the feed port of the forming shell 420, and the material blowing component is used to blow air into the packaging bag.

[0084] For specific implementation, see Figure 2 and Figure 3 As shown, the shaking material assembly 480 is composed of a telescopic cylinder, a shaking material block and a blowing material component.

More specifically, the blowing material component is composed of an air pipe and a fan, the end of the air pipe is located at the feed port, and the fan is located in the installation box. When the material needs to be shaken, the control system 3 is first used to control the telescopic cylinder to drive the shaking block to move back and forth. Since the shaking block will directly contact the back of the packaging bag, at this time, the shaking block keeps shaking the packaging bag, and then air is blown from top to bottom into the forming shell 420 through the air pipe on the blowing component, so that the product can smoothly enter the packaging bag from the forming shell 420. The products entering the packaging bag are gathered toward the bottom of the packaging bag due to the action of the blowing component, so as to gather the products in the effective space in the packaging bag.

[0085] In a preferred embodiment of the present invention, Figure 4 As shown, the packaging bag raw material assembly 410 includes a placement rack 411, two guide rods 413, a roll 412 and a film. The placement rack 411 is arranged on the frame 1, and the two guide rods 413 are arranged on the placement rack 411 at intervals. A guide groove is formed between the two guide rods. The roll 412 is rotatably arranged on the placement rack 411 and is located above the guide rods 413; one end of the film is wound on the roll 412, and the other end passes through the guide groove and is sleeved on the forming shell 420.

[0086] For specific implementation, please refer to Figure 1 , Figure 4 and Figure 5 The placing frame 411 is a frame composed of multiple connecting rods welded together. The placing frame 411 is installed on the control box. A rotatable reel 412 is arranged on the placing frame 411. One end of the film is wound on the reel 412. Two guide rods 413 are installed on the placing frame 411 below the reel 412. A guide groove is formed between the two guide rods 413. The other end of the film passes through the guide groove and is downwardly mounted on the forming shell 420, so that the film can be more easily formed into a bag shape under the guidance of the guide rod 413.

[0087] Further, in another embodiment, Figure 4 As shown, there is also a sliding rod 414 under the guide rod 413. The sliding rod 414 can be slidably installed on the placement rack 411. A sliding groove is set on the placement rack 411. The sliding rod 414 can slide in the sliding groove. The other end of the film passes through the guide groove and then the sliding rod 414, and finally is put on the molding shell 420, so that the film can be better wrapped around the molding shell 420.

[0088] In a preferred embodiment of the present invention, Figure 4 As shown, the film-drawing assembly 440 includes a film-drawing wheel pair 441 and a guide wheel pair 442.

The guide wheel pair 442 is installed in the transverse heat-sealing assembly 430 to guide the film to continue sliding. More specifically, the film-pulling wheel pair 441 is composed of a first pulley and a first motor. The first motor is installed in the control box. The first pulley is installed on the output shaft of the first motor. The vertical side of the film is between the two first pulleys. The guide wheel pair 442 is composed of a second pulley and a second motor. The second motor is installed in the control box. The second pulley is installed on the output shaft of the second motor. The peripheral side of the film is between the second pulleys. The guide spokes 442 can play a certain degree of guiding role, so that the peripheral side of the film continues to move downward along the first opening to maintain the size formed by the film. In actual use, since the vertical heat sealing component 450 needs to heat seal the vertical edge of the film, at this time, the film-pulling wheel pair 441 is installed under the vertical heat sealing component 450, which can drive the film to move downward, and the guide wheel pair 442 is installed in the horizontal heat sealing component 430. The film is guided to move by the guide wheel pair 442, so that the film can be moved by the film-pulling wheel pair 441 and the guide wheel pair 442, thereby achieving the film movement effect.

[0090] In a preferred embodiment of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, the transverse heat sealing assembly 430 includes a shell 453, two transverse cylinders 432 and two transverse heating plates 431.

[0092] In a preferred embodiment of the present invention, the cutting assembly 460 includes a cutter, which is disposed in the transverse heat sealing assembly 430 .

[0093] In a specific implementation, the cutter is a cutting machine used to cut the film to facilitate the forming of the packaging bag. The cutter is installed in the transverse heat sealing component 430 and is connected to the control system 3.

[0094] In another preferred embodiment, Figure 5 As shown, the cutter is configured as a blade, which is directly mounted on the transverse heating plate 431 and is located at the bottom of the transverse heating plate 431. It should be noted that the transverse heating plate 431 can be configured with a certain recessed size to facilitate the installation of the blade without affecting the closure of the transverse heating plate 431. By pre-setting the film size and stroke, when the peripheral side of the film reaches the transverse heating plate 431, the upper heating part of the transverse heating plate 431 is first used to clamp the film for transverse heat sealing, and after the heat sealing is completed, the lower blade of the transverse heating plate 431 is used to cut the film forming the bottom edge, which can not only save the space occupied by the transverse heat sealing assembly 430, but also reduce the equipment cost.

[0095] In a preferred embodiment of the present invention, Figure 5 As shown, the vertical heat sealing assembly 450 includes two vertical cylinders 452 and two vertical heating plates 451 . The two vertical cylinders 452 are arranged on the frame 1 at intervals, and the two vertical heating plates 451 are arranged on the two vertical cylinders 452 .

[0096] In specific implementation, Figure 5 As shown, two vertical cylinders 452 are respectively installed on the left and right sides of the control box, and two vertical heating plates 451 are arranged on the two vertical cylinders 452; more specifically, the combined positions of the vertical heating plates 451 correspond exactly to the gap positions of the film-drawing wheel pair 441; when the film is pulled by the film-drawing assembly 440, the vertical edge of the film is located in the two vertical heating plates 451, and the vertical edge of the film is also located in the two first film-drawing wheel spokes, that is, the vertical edge of the film can be pulled and the vertical edge of the film can be heat-sealed.

[0097] In a preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the discharging mechanism 5 includes a discharging machine 510 and a discharging belt 520. The discharging machine 510 is arranged on the frame 1, and the discharging belt 520 is arranged on the discharging machine 510. A plurality of discharging plates 530 are arranged at intervals on the discharging belt 520, and the input end of the discharging belt 520 is located in the shaking assembly 480.

[0098] In specific implementation, Figure 2 and Figure 4As shown, the discharging mechanism 5 includes a discharging machine 510 and a discharging belt 520. The discharging machine 510 is a belt conveyor, and the discharging belt 520 is equivalent to a belt. More specifically, the installation direction of the discharging machine 510 is as follows: Figure 1 As shown, the discharging belt 520 of the discharging machine 510 is gradually raised from right to left, and a plurality of discharging plates 530 are installed on the discharging belt 520, so that the packaging bags falling on the discharging belt 520 are not easy to slip off from the inclined discharging belt 520. It is worth noting that the lowest point of the discharging belt 520 is matched with the position of the shaking block, that is, the shaking block can play a certain guiding role, so that the packaging bags can just slide onto the discharging belt 520 under the action of the shaking surface of the shaking block, and then the discharging machine 510 is started, so as to output the finished packaging bags, reduce manual labor and improve work efficiency.

[0099] In a preferred embodiment of the present invention, Figure 4 As shown, the discharging belt 520 is provided with a discharging sensor for sensing the packaging bag, and the discharging sensor is electrically connected to the control system 3.

[0100] In specific implementation, Figure 4 As shown, the discharging sensor is any one of a photoelectric sensor, a weight sensor, an image sensor, and an infrared sensor, and the discharging sensor is installed at the lowest end of the discharging mechanism 5, that is, the lowest position of the discharging belt 520. More specifically, the discharging sensor is connected to the control system 3, and the control system 3 is connected to the discharging mechanism 5. When the discharging sensor senses that there are finished packaging bags, the discharging mechanism 5 is started to feed the materials. When the discharging sensor does not sense that there are finished packaging bags, the discharging mechanism 5 is not started, which can not only save the power of the discharging mechanism 5 and improve the economic benefits of the equipment, but also make the discharging mechanism 5 more automated and reduce the labor intensity.

[0101] Based on all the above embodiments, the use process of the utility model is as follows:

[0102] First, the film on the roll 412 is slid downward by the film-pulling wheel pair 441 and the guide wheel pair 442. When the film is pulled into the transverse heat-sealing assembly 430 and is at the position of the transverse cylinder 452 and the transverse heating plate 451, the bottom edge of the film is heat-sealed by the transverse cylinder 432 and the transverse heating plate 431 to form the initial bottom edge of the packaging bag.

[0103] Next, the film is continuously pulled from the roll 412 according to the preset film drawing length (color code) and number of times, so that after the film passes through the guide rod 413, the slide rod 414, and the forming shell 420, the openings at both ends of the film are located in the vertical heat sealing assembly 450. Each time the film is pulled, the vertical edge openings of the film are heat-sealed by the vertical heat sealing assembly 450. When the film is pulled to a suitable size, a packaging bag with an upward bag opening is formed.

[0104] Manually pour the required products into the feeding shell 211, and the products in the feeding shell 211 will smoothly fall onto the feeding belt 213, and the feeding sensor 215 on the feeding belt 213 will sense and trigger the feeder 212. The control system 3 starts the feeder 212 to transport the products on the feeding belt 213 to the feeding cylinder 220, and then smoothly enter the feed port of the forming shell 420 through the feeding cylinder 220, and then flow out from the feed port of the forming shell 420 to the discharge port. At this time, the product enters the bag opening of the packaging bag, and the vibration component 470 starts to vibrate the front and back of the packaging bag at a predetermined frequency and predetermined time to ensure that all the products enter the packaging bag. After the vibration ends, the shaking component 480 blows air into the bag opening of the packaging bag from top to bottom according to the set shaking times and in cooperation with the blowing component, which can ensure that all the products are effectively loaded into the limited space of the packaging bag. At this point, the packaging bag process is completed;

[0105] Finally, the transverse bag opening of the packaging bag is cut and heat-sealed by the transverse heat-sealing component 430 and the cutting component 460, and the packaging bag and the product are packaged. The vibration component 470 vibrates again to ensure that the packaging bag falls smoothly onto the discharge belt 520 of the discharge mechanism 5. The discharge sensor on the discharge belt 520 senses the finished packaging bag, and triggers the discharge machine 510 to take the finished packaging bag on the discharge belt 520 to complete the output of the finished packaging bag.

[0106] In summary, the utility model provides an automatic packaging device, which, by setting a frame, a feeding mechanism, a packaging bag forming mechanism, a discharging mechanism and a control system, first controls the feeding mechanism through the control system to feed the product to be packaged into the packaging bag forming mechanism, then controls the packaging bag forming mechanism through the control system to complete the packaging, and finally controls the discharging mechanism through the control system to output the packaged product, which can automatically complete the packaging of the product and can be reused, greatly improving the work efficiency.
