Description

Technical Field

[0001] This utility model relates to the technical field of bag feeding mechanisms, specifically a bag feeding mechanism for an automatic bag making machine with counting function. Background Technology

[0002] The bag feeding mechanism is a key component in packaging machinery, mainly used to accurately and efficiently transport packaging bags from one workstation to another. In automatic bag making machines, the bag feeding mechanism transports the packaging bags cut by the sealing and cutting mechanism to the bag receiving mechanism and packages the packaging bags and the goods. However, existing bag feeding mechanisms have some shortcomings in use. In order to meet market needs, there is a need for a bag feeding mechanism with counting function for automatic bag making machines.

[0003] Existing bag feeding mechanisms typically lack automatic counting capabilities, making it difficult to accurately count the number of bags fed and hindering real-time monitoring and adjustment of the production process. Furthermore, their guiding and feeding effects on the packaging bags are insufficient, preventing the mechanism from limiting the bags' movement during transport and compromising feeding accuracy. In addition, existing bag feeding mechanisms are inefficient, resulting in low bag feeding efficiency and reduced overall operational efficiency. Utility Model Content

A negative pressure tube is provided on the surface of the feeding plate. One end of the negative pressure tube is connected to the inside of the connecting tube. Multiple sets of negative pressure suction cups are arrayed on the surface of the bottom position of the feeding plate. The negative pressure suction cups are connected to the inside of the connecting tube. A laser positioning sensor is mounted on one side of the surface of the feeding plate by screws. The output end of the laser positioning sensor is electrically connected to the output end of the controller.

[0007] Preferably, the high-efficiency bag feeding mechanism consists of a servo motor, a rotating shaft, a holding cavity, a lead screw, an adjusting screw, and a guide groove. The holding cavity is formed on the inner wall of the mechanism frame, and a lead screw is installed inside the holding cavity. The lead screw rotates and engages with the inner wall of the holding cavity. An adjusting screw is threaded onto the surface of the lead screw. A guide groove is formed on the inner wall of the mechanism frame, and the guide groove slides and engages with the inner wall of the adjusting screw. The surface at the bottom of the adjusting screw is fixed to the surface at the top of the electric push rod.

[0008] Preferably, a servo motor is installed on the inner wall of the mechanism frame. The input end of the servo motor is electrically connected to the output end of the controller. The output end of the servo motor is connected to a rotating shaft via a coupling. One end of the rotating shaft extends into the interior of the holding cavity and is fixed to the surface of one end of the lead screw.

[0009] Preferably, the automatic counting mechanism consists of a mounting frame, mounting studs, a photosensitive counter, and a mounting block, and the mounting frame is provided on the surface of the top position of the baffle plate.

[0010] Preferably, two sets of mounting blocks are symmetrically mounted on the surfaces of both sides of the mounting frame. The mounting blocks are connected to the baffle plate by mounting studs. A photosensitive counter is installed on the inner wall of the mechanism frame. The output end of the photosensitive counter is electrically connected to the input end of the controller.

[0011] Preferably, the guiding and feeding mechanism includes an L-shaped support frame, a guide plate, a spring, a wheel frame, and a guide wheel. The L-shaped support frame is installed on the surfaces of both sides of the conveyor frame, the inner wall of the L-shaped support frame is provided with a guide plate, and the wheel frame is installed on the surface at the bottom of the guide plate.

[0012] Preferably, a guide wheel is provided on the inner side of the wheel frame. The guide wheel is used to limit the position of the packaging bag body. The guide wheel rotates and cooperates with the inner wall of the wheel frame. Multiple sets of elastic devices are installed in an array on the inner wall of the L-shaped support frame. The bottom end of the elastic device is fixed to the surface at the top position of the guide plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the automatic bag making machine with counting function can not only accurately count the number of bags fed, so as to monitor and adjust the production process in real time, but also limit the packaging bag body during the conveying process, and ensure the accuracy of feeding the packaging bag body. Moreover, it can efficiently feed the packaging bag body, making the working efficiency of the bag feeding mechanism higher.

[0014] 1. With an automatic counting mechanism, the user places the mounting frame on the surface of the baffle plate and tightens the mounting studs on the surface of the mounting block. Under the action of the mounting studs, the mounting frame is installed on the surface of the baffle plate. When the packaging bag passes under the photosensitive counter, the photosensitive counter generates an electrical signal, thereby realizing counting. The photosensitive counter can accurately count the number of bags fed and feed the data back to the controller. The counting result is displayed on the surface of the controller, realizing the automatic counting function of the bag feeding mechanism. This allows the bag feeding mechanism to accurately count the number of bags fed, so as to monitor and adjust the production process in real time.

[0015] 2. With the addition of a guiding feeding mechanism, after the conveying component transports the packaging bag body to the designated position, the packaging bag body will pass under the guide wheel. The packaging bag body drives the guide wheel to rotate on the inner wall of the wheel frame. Under the elastic force of the elastic device, a certain force is applied to the wheel frame and the guide wheel, which can guide and feed the two sides of the packaging bag body. At the same time, the elastic device, wheel frame and guide wheel will not affect the normal conveying efficiency of the conveying component to the packaging bag body. They only play the role of pressing and guiding the sides of the packaging bag body, realizing the function of guiding and feeding the packaging bag body by the bag feeding mechanism. This allows the bag feeding mechanism to limit the packaging bag body during conveying and ensure the accuracy of feeding the packaging bag body.

[0016] 3. A high-efficiency bag feeding mechanism is installed, controlling the operation of a servo motor inside the frame. The servo motor drives a rotating shaft, which in turn rotates a lead screw within the holding cavity. The lead screw, in its threaded engagement with the adjusting screw, slides along the inner wall of a guide groove, guiding the adjusting screw. As the adjusting screw moves, it drives an electric push rod, a feeding plate, and a negative pressure suction cup. The negative pressure suction cup supports the packaging bag body conveyed by the conveying components while simultaneously moving it towards the item to be packaged, placing the packaging bag body over the item's surface. This allows the item to be packaged inside the packaging bag body, achieving a highly efficient bag feeding function. This results in a more efficient bag feeding operation and higher working efficiency for the bag feeding mechanism. Attached Figure Description

[0024] The present invention provides a bag feeding mechanism for an automatic bag making machine with counting function, the structure of which is as follows: Figures 1 to 4As shown, the device includes a frame 1, a conveyor frame 14 mounted on the surface of the frame 1, a controller 11 (e.g., LA series) mounted on the surface of the conveyor frame 14, a conveying assembly 12 on the surface of the conveyor frame 14, a packaging bag body 13 on the top surface of the conveying assembly 12, and an electric push rod 15 (e.g., DG series) mounted on the inner wall of the frame 1. The input end of the electric push rod 15 is electrically connected to the output end of the controller 11, and a feeding plate 16 is mounted on the output end of the electric push rod 15 via screws. The feed plate 16 has a connecting pipe 17 installed inside. A negative pressure pipe 18 is provided on the surface of the feed plate 16. One end of the negative pressure pipe 18 is connected to the inside of the connecting pipe 17. Multiple sets of negative pressure suction cups 19 are installed in an array on the surface of the bottom position of the feed plate 16. The negative pressure suction cups 19 are connected to the inside of the connecting pipe 17. A laser positioning sensor 101 is installed on one side of the surface of the feed plate 16 by screws. The laser positioning sensor 101 can be of the LDM series. The output end of the laser positioning sensor 101 is electrically connected to the output end of the controller 11. A baffle plate 10 is installed on the surface of the conveying assembly 12.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, a high-efficiency bag feeding mechanism 2 is provided on the inner wall of the mechanism frame 1 and the surface of the electric push rod 15. The high-efficiency bag feeding mechanism 2 consists of a servo motor 21, a rotating shaft 22, a holding cavity 23, a lead screw 24, an adjusting screw 25, and a guide groove 26. The inner wall of the mechanism frame 1 has a holding cavity 23, and a lead screw 24 is installed inside the holding cavity 23. The lead screw 24 rotates and engages with the inner wall of the holding cavity 23. The adjusting screw 25 is threaded onto the surface of the lead screw 24. The inner wall of the mechanism frame 1 has a guide groove 26. The groove 26 and the inner wall of the adjusting screw 25 slide against each other. The surface at the bottom of the adjusting screw 25 is fixed to the surface at the top of the electric push rod 15. A servo motor 21 is installed on the inner wall of the mechanism frame 1. The servo motor 21 can be of the HF series. The input end of the servo motor 21 is electrically connected to the output end of the controller 11. The output end of the servo motor 21 is connected to a rotating shaft 22 through a coupling. One end of the rotating shaft 22 extends into the interior of the holding cavity 23 and is fixed to the surface of one end of the lead screw 24.

[0026] During implementation, the servo motor 21 inside the control mechanism frame 1 operates, driving the rotating shaft 22 to rotate. When the rotating shaft 22 rotates, it drives the lead screw 24 to rotate inside the holding cavity 23. Under the threaded engagement of the lead screw 24 and the adjusting screw 25, the adjusting screw 25 slides on the inner wall of the guide groove 26. Under the action of the guide groove 26, the adjusting screw 25 is guided. When the adjusting screw 25 moves, it drives the electric push rod 15, the feeding plate 16, and the negative pressure suction cup 19 to move. The negative pressure suction cup 19 supports the packaging bag body 13 conveyed on the surface of the conveying component 12 while moving towards the direction of the item to be packaged, so that the packaging bag body 13 is placed on the surface of the item, allowing the item to be packaged inside the packaging bag body 13, thereby realizing the efficient bag feeding function of the bag feeding mechanism.

[0027] Furthermore, such as Figure 2 and Figure 3 As shown, a guiding feeding mechanism 4 is provided on the surface of the conveyor frame 14. The guiding feeding mechanism 4 includes an L-shaped support frame 41, a guide plate 42, an elastic device 43, a wheel frame 44, and a guide wheel 45. The L-shaped support frame 41 is installed on both sides of the conveyor frame 14. The inner wall of the L-shaped support frame 41 is provided with a guide plate 42. The surface at the bottom of the guide plate 42 is provided with a wheel frame 44. The inner side of the wheel frame 44 is provided with a guide wheel 45. The guide wheel 45 is used to limit the positioning of the packaging bag body 13. The guide wheel 45 and the inner wall of the wheel frame 44 rotate and cooperate with each other. Multiple sets of elastic devices 43 are arrayed on the inner wall of the L-shaped support frame 41. The bottom end of the elastic device 43 is fixed to the surface at the top of the guide plate 42.

[0028] During implementation, the packaging bag body 13 passes under the guide wheel 45. The packaging bag body 13 drives the guide wheel 45 to rotate on the inner wall of the wheel frame 44. Under the elastic force of the elastic device 43, a certain force is applied to the wheel frame 44 and the guide wheel 45, which can guide and feed the two sides of the packaging bag body 13. At the same time, the elastic device 43, the wheel frame 44 and the guide wheel 45 will not affect the normal conveying efficiency of the conveying component 12 to the packaging bag body 13. They only play the role of pressing and guiding the sides of the packaging bag body 13, so as to realize the function of guiding and feeding the packaging bag body 13 by the bag feeding mechanism.

[0029] Furthermore, such as Figure 2 , Figure 3 and Figure 5As shown, an automatic counting mechanism 3 is provided on the surface of the baffle plate 10. The automatic counting mechanism 3 consists of a mounting frame 31, mounting studs 32, a photosensitive counter 33, and mounting blocks 34. The mounting frame 31 is provided on the surface at the top position of the baffle plate 10. Two sets of mounting blocks 34 are symmetrically installed on the surfaces on both sides of the mounting frame 31. The mounting blocks 34 are connected to the baffle plate 10 through mounting studs 32. A photosensitive counter 33 is installed on the inner wall of the mechanism frame 1. The photosensitive counter 33 can be of the LB series. The output terminal of the photosensitive counter 33 is electrically connected to the input terminal of the controller 11.

[0030] In practice, the user places the mounting bracket 31 on the surface of the baffle plate 10 and then tightens the mounting studs 32 on the surface of the mounting block 34. Under the action of the mounting studs 32, the mounting bracket 31 is installed on the surface of the baffle plate 10 for use. When the packaging bag body 13 passes under the photosensitive counter 33, the photosensitive counter 33 generates an electrical signal, thereby realizing counting. The photosensitive counter 33 can accurately count the number of bags fed and feed the data back to the controller 11. The counting result is displayed on the surface of the controller 11 to realize the automatic counting function of the bag feeding mechanism.

[0031] Working principle: In use, first place the frame 1 in the designated position, and install the conveyor frame 14 in the designated position of the automatic bag making machine using studs. The sealing and cutting machine of the automatic bag making machine will transport the cut packaging bags to the surface of the conveying component 12. Then, the controller 11 controls the conveying component 12 to start. After the conveying component 12 starts, it will transport the packaging bag body 13. The user places the mounting frame 31 on the surface of the baffle plate 10 and then tightens the mounting studs 32 on the surface of the mounting block 34. Under the action of the mounting studs 32, the mounting frame 31 is installed on the surface of the baffle plate 10 for use. When the packaging bag body 13 passes under the photosensitive counter 33, the photosensitive counter 33 will generate an electrical signal to achieve counting. The photosensitive counter 33 can accurately count the number of bags fed and feed the data back to the controller 11. The counting result is displayed on the surface of the controller 11 to realize the automatic counting function of the bag feeding mechanism. This allows the bag feeding mechanism to accurately count the number of bags fed, so as to monitor and adjust the production process in real time.

[0032] Subsequently, after the conveying assembly 12 conveys the packaging bag body 13 to the designated position, the packaging bag body 13 will pass under the guide wheel 45. The packaging bag body 13 drives the guide wheel 45 to rotate on the inner wall of the wheel frame 44. Under the elastic force of the elastic device 43, a certain force will be applied to the wheel frame 44 and the guide wheel 45, which can guide and feed the two sides of the packaging bag body 13. At the same time, the elastic device 43, the wheel frame 44 and the guide wheel 45 will not affect the normal conveying efficiency of the conveying assembly 12 to the packaging bag body 13. They only play the role of pressing and guiding the sides of the packaging bag body 13, so as to realize the function of guiding and feeding the packaging bag body 13 by the bag feeding mechanism. This allows the bag feeding mechanism to limit the packaging bag body 13 during conveying and ensure the accuracy of feeding the packaging bag body 13.

[0033] Subsequently, when the laser positioning sensor 101 senses the position of the packaging bag body 13, the controller 11 controls the electric push rod 15 to work. Under the action of the electric push rod 15, the feeding plate 16 and the negative pressure suction cup 19 move downward, so that the bottom surface of the negative pressure suction cup 19 moves downward to contact the surface of the packaging bag body 13. Under the action of the negative pressure pipe 18 and the connecting pipe 17, a negative pressure environment is generated inside the negative pressure suction cup 19, ensuring that the negative pressure suction cup 19 can suck up the surface of the packaging bag body 13. Then, the controller 11 controls the electric push rod 15 to move upward to reset. The electric push rod 15 drives the feeding plate 16 and the negative pressure suction cup 19 to move upward. At this time, the negative pressure suction cup 19 can open the packaging bag body 13 to the required position, so that the packaging bag body 13 does not need an additional bag-opening mechanism to open the bag.

[0034] Subsequently, the controller 11 controls the servo motor 21 inside the frame 1 to operate. Under the action of the servo motor 21, the rotating shaft 22 rotates. When the rotating shaft 22 rotates, it drives the lead screw 24 to rotate inside the holding cavity 23. Under the threaded engagement between the lead screw 24 and the adjusting screw 25, the adjusting screw 25 slides on the inner wall of the guide groove 26. Under the action of the guide groove 26, the adjusting screw 25 is guided. When the adjusting screw 25 moves, it drives the electric push rod 15, the feeding plate 16, and the negative pressure suction cup 19 to move. The negative pressure suction cup 19 then moves the conveying assembly 1. 2. While the packaging bag body 13 is being conveyed on the surface, it moves towards the item to be packaged, placing the packaging bag body 13 over the surface of the item so that the item can be packaged inside the packaging bag body 13. Subsequently, the high-efficiency bag feeding mechanism 2 drives the electric push rod 15, the feeding plate 16 and the negative pressure suction cup 19 to reset, preparing for the next bag feeding operation, so as to realize the efficient bag feeding function of the bag feeding mechanism. This allows the bag feeding mechanism to efficiently feed the packaging bag body 13 during use, making the bag feeding mechanism more efficient during use, and finally completing the use of the bag feeding mechanism.
