Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology transformation, and in particular to a feeding structure for a PE bag packaging machine. Background Technology

[0002] Packaging machine technology upgrades are an important means to improve production efficiency, reduce costs, and improve product quality. Among them, PE bag packaging machines are automated equipment specifically designed to package products in polyethylene (PE) bags. They are widely used in industries such as food, pharmaceuticals, chemicals, and daily necessities. They can efficiently complete product packaging, improve production efficiency, ensure packaging quality, and meet the packaging needs of different industries.

[0003] Chinese patent discloses a feeding device for an efficient automatic PE bag packaging machine (authorization announcement number CN206125550U). This patented technology uses an automated mechanism to achieve the adsorption, flipping, lifting, and lateral movement of PE bags, thus achieving automatic feeding. Multiple PE bags can be adsorbed at once, facilitating the simultaneous packaging of multiple products and significantly improving packaging efficiency. It boasts advantages such as high automation and good product consistency. However, the inventors discovered that during the use of the aforementioned feeding device, the PE bags cannot expel internal air during transport, easily leading to bag expansion or irregular shape. This not only affects the appearance quality of the PE bags but may also cause bag jamming and blockages in subsequent packaging processes, impacting production efficiency or affecting the precise positioning of the equipment, thereby affecting the stability and reliability of the entire packaging process. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing device does not have the function of effectively expelling the air inside the PE bag, which leads to the PE bag easily expanding and becoming irregular in shape during the conveying and use process. To this end, we propose a feeding structure for a PE bag packaging machine.

[0005] To achieve the above objectives, this application adopts the following technical solution: a feeding structure for a PE bag packaging machine, including a base, a control console mounted on one side of the base, a support mounted on the top of the base, a conveyor belt mounted on the top of the support, a servo motor mounted on one side of the support near the conveyor belt, a pressing roller mounted on the output end of the servo motor, an inclined surface mounted on one end of the conveyor belt, a rotary motor mounted inside one end of the support, a transmission turntable mounted on the output end of the rotary motor, a cylinder moving support mounted on one side of the support, and a guide rail cooperating with the cylinder moving support inside the support. The telescopic end of the movable support is equipped with an induction suction cup. A feeding box is placed on the inner wall of the support. A first lifting cylinder is installed at the bottom of the base. A sliding plate aligned with the telescopic end of the first lifting cylinder is installed at the bottom of the feeding box. A motor rotating support is installed at one end of the top of the base. A T-shaped support is fixedly connected to the inner wall of the motor rotating support. A motor rotating lower clamp is installed at both ends of the T-shaped support. A second lifting cylinder is installed at the bottom of one end of the motor rotating lower clamp. An upper clamp is installed at the telescopic end of the second lifting cylinder. A bag opening device is installed at one end of the top of the base. A feeding conveyor belt is installed on one side of the top of the base.

[0006] Preferably, both sides of the feeding box are fixedly connected to the groove blocks, and both sides of one end of the bracket are rotatably connected to the clips via a rotating shaft, with one end of the clips forming an insertion connection with the inner wall of the groove block.

[0007] Preferably, an extension block is fixedly connected to one side of the feeding box, and a limiting rod is slidably connected to the inner wall of the extension block. The inner wall of the limiting rod is slidably connected to the surface of the clamp.

[0008] Preferably, one end of the limiting rod has a circular groove, and a sliding rod is slidably connected to the inner wall of the circular groove. The two ends of the sliding rod are fixedly connected to the inner wall of the extension block.

[0009] Preferably, a spring is fixedly connected to one side of the limiting rod, and the other end of the spring is fixedly connected to one side of the inner wall of the extension block, with the spring sleeved on the outer periphery of the slide rod.

[0010] Preferably, a moving assist device is installed around the bottom of the feeding box, and a discharge slope is installed at one end of the base.

[0011] Preferably, the bracket has mounting slots on both sides inside, a drive motor is installed inside the mounting slot, and a guide plate is installed at the output end of the drive motor.

[0012] Technical effects and advantages of this utility model:

[0013] In this invention, when the user transports the PE bag to the next process via the feeding conveyor belt, the servo motor drives the crushing roller to crush the PE bag, effectively expelling the air inside the bag and keeping it flat during transport. This avoids expansion or irregular shape caused by air inside the bag, thereby improving the stability of the PE bag during transport. When the PE bag is transported to the front end of the conveyor belt and enters the transmission turntable along the inclined surface, the rotating motor drives the transmission turntable to rotate, ensuring that the bag opening of the PE bag always faces forward. This precise positioning operation provides a stable prerequisite for the subsequent bag opening and clamping processes, ensuring the stability and reliability of the PE bag in each stage.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a feeding structure for a PE bag packaging machine, including a base 1, a control console 2 installed on one side of the base 1, a bracket 3 installed on the top of the base 1, a conveyor belt 4 installed on the top of the bracket 3, a servo motor 5 installed on one side of the bracket 3 near the conveyor belt 4, a crushing roller 6 installed at the output end of the servo motor 5, an inclined surface 7 installed at one end of the conveyor belt 4, a rotary motor 8 installed inside one end of the bracket 3, a transmission turntable 9 installed at the output end of the rotary motor 8, a cylinder moving bracket 10 installed on one side of the bracket 3, a guide rail 11 cooperating with the cylinder moving bracket 10 inside the bracket 3, an induction suction cup 12 installed at the telescopic end of the cylinder moving bracket 10, and a feeding box 13 placed on the inner wall of the bracket 3. A first lifting cylinder 14 is installed at the bottom of the base 1. A sliding plate 15 aligned with the telescopic end of the first lifting cylinder 14 is installed at the bottom of the feeding box 13. A motor rotating bracket 16 is installed at one end of the top of the base 1. A T-shaped bracket 17 is fixedly connected to the inner wall of the motor rotating bracket 16. A motor rotating lower clamping plate 18 is installed at both ends of the T-shaped bracket 17. A second lifting cylinder 19 is installed at the bottom of one end of the motor rotating lower clamping plate 18. An upper clamping plate 20 is installed at the telescopic end of the second lifting cylinder 19. A bag opening device 21 is installed at one end of the top of the base 1. A feeding conveyor belt 22 is installed on one side of the top of the base 1. When the user needs to start the equipment for production, the user places the feeding box 13 filled with PE bags into the feeding trough of the feeding box 13. Afterwards, the user starts the equipment via the control panel 2. This drives the first lifting cylinder 14 to extend and retract upwards, pushing the sliding plate 15 inside the loading box 13. When the induction suction cup 12 on the inner wall of the guide rail 11 senses the PE bag, the cylinder moving bracket 10 drives the induction suction cup 12 to suck up the PE bag on top of the loading box 13. The cylinder moving bracket 10 then moves along the inner wall of the guide rail 11 to the top of the conveyor belt 4, lowering the PE bag. The bag is then driven forward on the conveyor belt 4 with its tail as the front end. The servo motor 5 drives the crushing roller 6 to crush the PE bag on the surface of the conveyor belt 4, squeezing out the air inside. When the bag reaches the front end of the conveyor belt 4, it is fed along the inclined plane 7 onto the surface of the transmission turntable 9. At this time, the rotating motor 8 rotates the transmission turntable 9. The turntable 9 rotates, causing the PE bag's opening to face forward. The conveyor belt inside the turntable 9 then transports the bag to a designated position. The motor-driven bracket 16 rotates via a bottom motor, aligning the T-shaped bracket 17 with the turntable 9. The second lifting cylinder 19 drives the upper clamping plate 20 and the lower clamping plate 18 to clamp the PE bag. The lower clamping plate 18 is then driven by the motor to stand the PE bag upright. The motor-driven bracket 16 then rotates again. When the T-shaped bracket 17 reaches the position of the bag-opening device 21, the pneumatic opening head of the bag-opening device 21 opens the PE bag on the T-shaped bracket 17. After the PE bag is opened, the motor-driven bracket 16 rotates the bag to the top of the unloading conveyor belt 22.The extension and retraction of the second lifting cylinder 19 causes the motor to rotate, releasing the PE bag held by the lower clamping plate 18 and upper clamping plate 20. This allows the bag to fall onto the surface of the feeding conveyor belt 22 and be transported to the next process. The servo motor 5 drives the crushing roller 6 to crush the PE bag, effectively expelling air from the bag and keeping it flat during transport. This prevents expansion or irregular shape caused by air inside the bag, thus improving the stability of the PE bag during transport. When the PE bag reaches the front end of the conveyor belt 4 and enters the transmission turntable 9 along the inclined plane 7, the rotating motor 8 drives the transmission turntable 9 to rotate, ensuring that the bag opening always faces forward. This precise positioning operation provides a stable prerequisite for subsequent bag opening and clamping processes, ensuring the stability and reliability of the PE bag at each stage.

[0022] Reference Figure 1 and Figure 5 As shown in this embodiment: both sides of the feeding box 13 are fixedly connected to the groove block 23, and both sides of one end of the bracket 3 are rotatably connected to the clamp 24 through the rotating shaft. One end of the clamp 24 is inserted into the inner wall of the groove block 23. When the user places the feeding box 13 into the feeding groove of the control console 2, the clamp 24 is rotated through the rotating shaft to make one end of the clamp 24 insert into the inner wall of the groove block 23, thereby fixing the position of the feeding box 13.

[0023] Reference Figure 1 and Figure 5 As shown in this embodiment: an extension block 25 is fixedly connected to one side of the feeding box 13, and a limiting rod 26 is slidably connected to the inner wall of the extension block 25. The inner wall of the limiting rod 26 is slidably connected to the surface of the clamp 24. When the user inserts the clamp 24 into the extension block 25, the user moves the limiting rod 26 through the inner wall of the extension block 25, so that the inner wall of the limiting rod 26 restricts the surface of the clamp 24, preventing the clamps 24 on both sides from unfolding to the sides. The limiting rod 26 restricts the clamps 24, making the insertion of the clamps 24 into the slot block 23 more secure.

[0024] Reference Figure 1 and Figure 5 As shown in this embodiment: a circular groove 27 is provided at one end of the limiting rod 26, and a sliding rod 28 is slidably connected to the inner wall of the circular groove 27. The two ends of the sliding rod 28 are fixedly connected to the inner wall of the extension block 25. When the user moves the limiting rod 26 through the circular groove 27 on the surface of the sliding rod 28, the limiting rod 26 is more stable when moving on the inner wall of the extension block 25.

[0025] Reference Figure 1 and Figure 5As shown in this embodiment: a spring 29 is fixedly connected to one side of the limiting rod 26, and the other end of the spring 29 is fixedly connected to one side of the inner wall of the extension block 25. The spring 29 is sleeved on the outer periphery of the slide rod 28. When the user is about to move the limiting rod 26 along the inner wall of the extension block 25 to release the restriction of the clip 24, the limiting rod 26 compresses the spring 29 to store force. When the user is about to move the limiting rod 26 back to its original position, the user releases the limiting rod 26, causing the spring 29 to release and rebound, pushing the limiting rod 26 back to its original position. The spring 29 makes the operation of the device simpler.

[0026] Reference Figure 1 and Figure 4 As shown in this embodiment: a moving assist device 30 is installed around the bottom of the feeding box 13, and a discharge slope 31 is installed at one end of the base 1. When the user is about to move the feeding box 13 out of the slot of the control console 2, the user pulls the limiting lever 26 to move the feeding box 13 out of the equipment along the inclined surface of the mounting slot 32 through the moving assist device 30 for replacement. The inclined surface design of the mounting slot 32 makes the movement of the feeding box 13 smoother and reduces the resistance during the replacement process. The cooperation between the limiting lever 26 and the moving assist device 30 allows the user to easily control the movement of the feeding box 13, improving the efficiency of the equipment for material replacement. This design not only simplifies the steps of replacing the feeding box 13, but also ensures the stability and safety of the replacement process, making the feeding structure of the entire PE bag packaging machine more efficient and reliable.

[0027] Reference Figure 1 and Figure 4 As shown in this embodiment: mounting slots 32 are provided on both sides inside the bracket 3. A drive motor 33 is installed inside the mounting slot 32. A guide plate 34 is installed at the output end of the drive motor 33. When the user starts the equipment and moves the PE bag on the surface of the conveyor belt 4, the drive motor 33 inside the mounting slot 32 drives the guide plate 34 to adjust the spacing of the guide plates 34 on both sides according to the specifications of the PE bag, thereby limiting the conveying direction of the PE bag on the surface of the conveyor belt 4, so as to ensure that the PE bag will not deviate or slip during the conveying process, thus improving the accuracy and stability of packaging.

[0028] Working principle:

[0029] Step 1: When the user needs to start the equipment for production, first place the feeding box 13 filled with PE bags into the feeding trough of the feeding box 13. Then start the equipment through the control console 2. The first lifting cylinder 14 extends and retracts upward, pushing the sliding plate 15 inside the feeding box 13. When the induction suction cup 12 on the inner wall of the guide rail 11 senses the PE bag, the cylinder moving bracket 10 drives the induction suction cup 12 to suck up the PE bag on the top of the feeding box 13 and move it along the inner wall of the guide rail 11 to the top of the conveyor belt 4, putting the PE bag down so that it is transmitted forward through the conveyor belt 4 with its tail as the front end. The servo motor 5 drives the crushing roller 6 to crush the PE bag in the transmission, expelling the air inside the bag and ensuring that the PE bag remains flat during the transmission process, avoiding expansion or irregular shape caused by air inside the bag, thereby improving the transmission stability. When the PE bag is transmitted to the front end of the conveyor belt 4 and along the inclined... When the PE bag is fed into the transmission turntable 9, the rotating motor 8 drives the transmission turntable 9 to rotate, ensuring that the opening of the PE bag always faces forward, providing a stable condition for subsequent bag opening and clamping processes. The motor rotating bracket 16 is driven to rotate by the bottom motor, aligning the T-shaped bracket 17 with the transmission turntable 9. The second lifting cylinder 19 drives the upper clamping plate 20 and the clamping plate at one end of the lower clamping plate 18 to clamp the PE bag. The lower clamping plate 18 drives the PE bag to stand upright. The motor rotating bracket 16 rotates again. When the T-shaped bracket 17 rotates to the position of the bag opening device 21, the pneumatic bag opening head of the bag opening device 21 opens the PE bag. After the bag is opened, the motor rotating bracket 16 rotates it to the top of the unloading conveyor belt 22. The second lifting cylinder 19 extends and retracts, causing the lower clamping plate 18 and the upper clamping plate 20 to release the PE bag, allowing it to fall onto the surface of the unloading conveyor belt 22 and be conveyed to the next process.

[0030] Step two: After the user places the feeding box 13 into the feeding slot of the control console 2, the user rotates the clamp 24 so that one end of it is inserted into the inner wall of the slot block 23 to fix the position of the feeding box 13. The user then inserts the clamp 24 into the extension block 25 and pushes the limiting rod 26 to move along the inner wall of the extension block 25 so that the inner wall of the clamp 24 is restricted to prevent it from unfolding to both sides, thus enhancing the firmness of the insertion. The limiting rod 26 moves through the circular groove 27 on the surface of the slide rod 28 to ensure stable movement. When it is necessary to release the restriction, the user pulls the limiting rod 26 to compress the spring 29. After releasing, the spring 29 releases and rebounds, pushing the limiting rod 26 back to its original position.

[0031] Step 3: When the user is about to move the loading box 13 out of the control console 2, by pulling the limiting lever 26, the loading box 13 is smoothly moved out of the equipment along the inclined surface of the mounting groove 32 for replacement with the help of the moving assist device 30. The inclined surface design of the mounting groove 32 reduces the moving resistance, and the cooperation between the limiting lever 26 and the moving assist device 30 allows the user to easily control the movement of the loading box 13, improving the material replacement efficiency, simplifying the replacement steps, ensuring the stability and safety of the process, and making the feeding structure more efficient and reliable. After the equipment is started, the drive motor 33 in the mounting groove 32 drives the guide plate 34, and adjusts the distance between the two guide plates 34 according to the PE bag specifications, limiting the conveying direction of the PE bag on the conveyor belt 4 to prevent it from deviating or slipping.
