Description

Technical Field

[0001] The invention relates to the technical field of bag making machine design, in particular to a high-protective conveying mechanism for a bag making machine. Background Art

[0002] A bag making machine is a machine used to make various plastic bags or bags of other materials. Taking the production of plastic vest bags as an example, the bag making machine generally needs to fold, hot-press, cut the raw materials into bags and stack them for transportation. In order to facilitate cutting out the shape of the vest bags, it is also necessary to cut off the excess materials at one time when the bags are stacked to form the shape of the vest bags.

[0003] However, in this processing flow, multiple factors will affect the working stability and safety of the processing process. First of all, the transportation mechanism itself needs to cooperate with the cutting knife to perform the final cutting of the bag, and the existing transportation mechanism lacks isolation protection. It is easy for the operator to touch the knife or other moving parts due to misoperation and cause accidents. At the same time, if external foreign matter enters the transportation mechanism, the existing transportation mechanism cannot identify and discharge these foreign matter, thereby causing safety hazards. At the same time, the existing transportation mechanism cannot ensure the accuracy of the cutting process, which can easily cause uneven cutting surfaces. Waste chips are mixed near the bags that have not been cut and spread to other areas during subsequent transportation. At the same time, the waste chips cannot be effectively discharged after cutting, so it is easy for the waste chips to affect the normal operation of the equipment, thereby causing safety hazards.

[0004] Therefore, we need a highly protective conveying mechanism for bag making machines to solve the problem of lack of safety protection in the existing transportation mechanism of bag making machines, which can effectively reduce safety hazards and improve the working stability of the equipment.

[0035] Embodiment 1

[0036] See also Figures 1 to 8 The present invention provides a technical solution: a highly protective conveying mechanism for a bag making machine, comprising:

[0037] Rack 1, see Figures 1 to 4 The frame 1 is provided with a first conveyor belt 11 for transporting bags 18 and a second conveyor belt 13 for transporting cutting waste, and a material guide table 12 arranged above the first conveyor belt 11 and the second conveyor belt 13 is fixedly installed on the frame 1, and a protective shell 17 is fixedly installed on the outer side of the frame 1, and a protective door 15 for easy maintenance is hingedly installed on the protective shell 17. The protective shell 17 is used to isolate the transport mechanism from the external space, so as to prevent external debris from falling into the transport mechanism, and also to avoid accidents caused by operators being too close to the transport mechanism, so that the transport mechanism can work stably. After the protective door 15 is opened, it is convenient for maintenance personnel to maintain the interior of the transport mechanism;

[0038] Feeding station 9, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 8The receiving platform 9 is used to dock with the discharge port of the external cutting device. The external cutting device cuts the raw materials of the bag 18 and separates them into individual bags 18 and sends them to the receiving platform 9 for stacking.

The adjusting push rod 201 and the extruding push rod 204 are both electrically connected to the controller 10, and the controller 10 is electrically connected to the adjusting push rod 201. The drive of the overdrive motor 8 can make the rotating guide plate 7 overlap the material guide table 12 or rotate to a position parallel to the material receiving table 9. When the rotating guide plate 7 overlaps the material guide table 12, the bag 18 can be moved to the material guide table 12 under the push of the pushing device 3, and when the rotating guide plate 7 moves to a horizontal position with the material receiving table 9, the cutting device 2 can move to the top of the material guide table 12 and then cut the bags 18 in a stacked state above the material guide table 12. Specifically, first adjust the push rod 201 to push the movable frame 203 to the designated working position on the material guide table 12, and then squeeze the cutting knife 202 downward by squeezing the push rod 204 so as to use the cutting knife 202 to cut the bags 18 in a stacked state, and then adjust the push rod 201 to pull the cutting knife 202 back to the rear end and use the cutting knife 202 to push the waste generated after cutting to the second conveyor belt 13 for discharge, and then adjust the push rod 201 and the squeezing push rod 204 to return to the initial state again and wait for the next cutting;

[0039] Beam 5, see Figure 2 , Figure 3 and Figure 5A second screw motor 6 is fixedly mounted on the cross beam 5, and the second screw motor 6 drives a pushing device 3 that moves along the cross beam 5 through a screw rod. The pushing device 3 is used to push the bag 18 to move and scrape and clean the surfaces of the docking station 9, the rotating guide plate 7 and the guide station 12. The pushing device 3 includes a moving seat 301 that is slidably mounted with the cross beam 5 and driven by the second screw motor 6, and a multi-stage telescopic push rod 303 is fixedly mounted on the bottom of the moving seat 301, and a pressing plate 304 for pressing the bag 18 is installed at the output end of the multi-stage telescopic push rod 303, and a pair of second angle adjustment members are fixedly mounted at the rear end of the pressing plate 304. The motor 306 is provided, and the output end of the second angle adjustment motor 306 drives a push piece 308 for pushing the bag 18 to move. The front end of the pressing plate 304 is fixedly installed with a scraper 307 for scraping the surfaces of the docking material platform 9, the material guide platform 12 and the rotating guide plate 7. The multi-stage telescopic push rod 303 and the second angle adjustment motor 306 are both electrically connected to the controller 10. The output end of the multi-stage telescopic push rod 303 is fixedly installed with a first angle adjustment motor 305, and the output end of the first angle adjustment motor 305 is used to drive the pressing plate 304 to rotate. The first angle adjustment motor 305 is electrically connected to the controller 10, through The second screw motor 6 can drive the pushing device 3 to move forward and backward along the cross beam 5, and the multi-stage telescopic push rod 303 can change the up and down position of the pressure plate 304, thereby driving the pushing device 3 to work. The pushing device 3 adopts the following three stages to work in stages: in the first stage, when the bags 18 on the receiving platform 9 are stacked to a specified number, the pushing device 3 is driven by the second screw motor 6 to move to the working position at the top of the receiving platform 9, and then the second angle adjustment motor 306 rotates the pushing piece 308 to the specified working angle, and at the same time the first angle adjustment motor 305 rotates the pressure plate 304 to the specified The push piece 308 is pushed to the position where it fits the top of the receiving platform 9 through the multi-stage telescopic push rod 303. At the same time, the rotating guide plate 7 is pre-rotated to the position where it overlaps with the guide platform 12. The limiting device 4 on the receiving platform 9 will also stop limiting. Then the second screw motor 6 drives the pushing device 3 to move forward. At this time, the pushing piece 308 will also push the rear end of the bag 18 so that the bag 18 can move along the rotating guide plate 7 to the guide platform 12. Then the limiting device 4 on the receiving platform 9 re-enters the limiting state, and the rotating guide plate 7 returns to the position parallel to the receiving platform 9.In the second stage, when the bags 18 in the stacked state move into the limiting device 4 located on the material guide table 12, the second screw motor 6 fine-tunes the position of the pushing device 3, thereby using the pushing piece 308 to push the rear end of the bags 18 in the stacked state so that the rear end of each bag 18 is aligned with the surface of the pushing piece 308 as the reference plane, and then the pushing piece 308 is rotated to the non-working position, and then the multi-stage telescopic push rod 303 drives the pressing plate 304 to press downward. At this time, the upper surface of the bags 18 in the stacked state can be flattened by the pressing plate 304, and then the pushing device 3 retreats upward to the non-working position, and then the bags 18 are cut by the cutting device 2. After the cutting is completed, the limiting device 4 located on the material guide table 12 is adjusted to the non-working state, and the bags 18 that have been cut are pushed to the first conveyor belt 11 by the pushing device 3 again, and then the pushing device 3 enters the third stage; in the third stage, when the pushing device 3 pushes the bags After the scraper 307 is sent onto the first conveyor belt 11, the pushing device 3 returns to the cleaning working position of the material receiving platform 9, and then adjusts the scraper 307 to a position perpendicular to the ground through the first angle adjustment motor 305, and then adjusts the scraper 307 to a position that fits the upper surface of the material receiving platform 9 through the multi-stage telescopic push rod 303. This position is close to the rotating guide plate 7 and will not affect the normal operation of the limit device 4 on the material receiving platform 9. At the same time, the rotating guide plate 7 is again overlapped with the material guide platform 12. Then the second screw motor 6 drives the pushing device 3 to move forward. At this time, the position of the scraper 307 is adjusted by the multi-stage telescopic push rod 303, so that the scraper 307 can scrape and brush the upper surface of the material receiving platform 9, the upper surface of the rotating guide plate 7 and the upper surface of the material guide platform 12 in turn, thereby removing the debris on the material receiving platform 9, the rotating guide plate 7 and the material guide platform 12. After the scraping and brushing is completed, the pushing device 3 returns to the top of the material receiving platform 9 and waits to re-enter the first stage;

[0040] Controller 10, see Figures 1 to 3 , the controller 10 is fixedly mounted on the frame 1, and the controller 10 is electrically connected to the drive motor 8;

[0041] See also Figure 2 , Figure 3 and Figure 6The limiting device 4 includes a mounting frame 402 fixedly mounted on the material receiving platform 9 or the material guiding platform 12, and a pair of first screw motors 401 are fixedly mounted on the mounting frame 402, and the output end of each first screw motor 401 drives a side limiting piece 403 sliding along the top of the mounting frame 402, and the side limiting piece 403 is used to limit the side of the bag 18, and a third angle adjustment motor 405 is fixedly mounted on the front end of the side limiting piece 403, and the output end of the third angle adjustment motor 405 drives a front baffle 406 for limiting the moving position of the front end of the bag 18, and the first screw motor 401 and the third angle adjustment motor 405 are both electrically connected to the controller 10, and a guide plate 404 for guiding the bag 18 to enter the middle of the two side limiting pieces 403 is fixedly mounted on the side limiting piece 403, The guide plate 404 is an arc-shaped guide plate. When the limit device 4 enters the working state, the two first screw motors 401 are used to adjust the left and right positions of the side limit plates 403, so that the side limit plates 403 limit the movement path of the bag 18. At the same time, the third angle adjustment motor 405 is used to adjust the front baffle 406 to a horizontal position, so that the front baffle 406 can be used to block the position of the front end of the bag 18, so that the bags 18 can be aligned with the end face of the front baffle 406 when stacking, thus avoiding the problem of misalignment of bags 18 at different heights when cutting. When the limit device 4 does not need to work, the third angle adjustment motor 405 will drive the front baffle 406 to rotate to a position perpendicular to the ground, so that the front baffle 406 will no longer prevent the movement of the bag 18.

[0042] In this embodiment, the bags 18 in a stacked state can be sent to the cutting device 2 and accurately cut under the precise pushing of the pushing device 3 and the precise limiting of the limiting device 4, and the waste generated after cutting will also be discharged by the second conveyor belt 13. At the same time, the pushing device 3 can also identify obstacles and remove obstacles to reduce safety risks. The protective shell 17 arranged on the frame 1 can also prevent obstacles from entering the conveying mechanism, and at the same time, it also avoids the problem of accidents caused by direct contact between the operator and the inside of the transportation mechanism, thereby solving the problem of lack of safety protection of the transportation mechanism of the existing bag making machine, which can effectively reduce safety hazards and improve the working stability of the equipment.

[0043] Embodiment 2

[0044] See also Figure 2 , Figure 3 and Figure 5On the basis of the first embodiment, a camera 302 is fixedly installed on the movable seat 301 for identifying debris on the surfaces of the docking station 9, the guide station 12 and the rotating guide plate 7 through image recognition technology, and the camera 302 is electrically connected to the controller 10. By installing the camera 302 on the movable seat 301, the pushing device 3 can collect images through the camera 302 during the movement, so as to timely identify abnormal debris through the image recognition system located in the controller 10. In this way, when the bag 18 cannot be discharged normally through the first conveyor belt 11, the external foreign matter enters the path where the bag 18 needs to move, etc., the production line can be stopped in time through the controller 10, thereby avoiding further failures, effectively ensuring the safety of the equipment, and further solving the problem of lack of safety protection of the transportation mechanism of the existing bag making machine. It can effectively reduce safety hazards and improve the working stability of the equipment.

A travel switch 16 for detecting the opening and closing state between the protective door 15 and the protective shell 17 is fixedly installed on the protective door 15, and the travel switch 16 is electrically connected to the controller 10. When the transportation mechanism is in a normal working state, the operator can observe the working process of the element mechanism through the transparent observation windows located on the protective door 15 and the protective shell 17. When the transportation mechanism needs to be maintained, the staff can perform maintenance operations by opening the protective door 15. When the protective door 15 is opened, the travel switch 16 is triggered. At this time, the controller 10 will stop the operation process of the production line, thereby avoiding the problem of accidents when the operator contacts the conveying mechanism without closing the production line, thereby improving the safety of production, further solving the problem of lack of safety protection of the transportation mechanism of the existing bag making machine, and can effectively reduce safety hazards and improve the working stability of the equipment.

[0047] Embodiment 4

[0048] On the basis of the third embodiment, the present invention further provides a method for using a high-protection conveying mechanism for a bag making machine, comprising the following steps:

[0049] Step 1: When the bag making machine is working, the bags 18 cut out by the cutting device of the bag making machine will fall into the limiting device 4 on the receiving platform 9, and will be docked in an aligned manner under the limiting position of the limiting device 4. When the bags 18 on the receiving platform 9 are stacked to a specified number, the pushing device 3 is driven by the second screw motor 6 to move to the working position at the top of the receiving platform 9, and then the second angle adjustment motor 306 rotates the pushing piece 308 to the specified working angle, and at the same time the first angle adjustment motor 305 rotates the pressing plate 304 to the specified angle, and then the pushing piece 308 is rotated to the specified working angle through the multi-stage telescopic push rod 303. The bag 18 is moved downward to the position where it fits the top of the receiving platform 9, and the rotating guide plate 7 is rotated to the position where it overlaps with the material guide platform 12 in advance. The limiting device 4 on the receiving platform 9 will also stop limiting, and then the second screw motor 6 drives the pushing device 3 to move forward. At this time, the pushing piece 308 will also push the rear end of the bag 18 so that the bag 18 can move along the rotating guide plate 7 to the material guide platform 12. Then the limiting device 4 on the receiving platform 9 re-enters the limiting state and can continue to receive the bag 18 provided by the external cutting device. At the same time, the rotating guide plate 7 returns to a position parallel to the receiving platform 9.

[0050] Step 2: When the bags 18 in the stacked state move into the limiting device 4 on the material guide table 12 under the push of the pushing piece 308, the second screw motor 6 fine-tunes the position of the pushing device 3, so that the pushing piece 308 is used to push the rear end of the bags 18 in the stacked state so that the rear end of each bag 18 is aligned with the surface of the pushing piece 308 as the reference plane, and then the pushing piece 308 is rotated to the non-working position, and then the multi-stage telescopic push rod 303 drives the pressing plate 304 to press downward, at this time, the upper surface of the bags 18 in the stacked state can be flattened by the pressing plate 304, and then the pushing device 3 retreats upward to the non-working position, and then the bags 18 are cut by the cutting device 2. After the cutting is completed, the limiting device 4 on the material guide table 12 is adjusted to the non-working state, and the bags 18 that have been cut are pushed to the first conveyor belt 11 by the pushing device 3 again using the pushing piece 308;

[0051] Step 3: After the pushing device 3 delivers the bag 18 onto the first conveyor belt 11, the pushing device 3 returns to the cleaning working position of the receiving platform 9, and then the scraper 307 is adjusted to a position perpendicular to the ground through the first angle adjustment motor 305, and then the scraper 307 is adjusted to a position in contact with the upper surface of the receiving platform 9 through the multi-stage telescopic push rod 303. This position is close to the rotating guide plate 7 and will not affect the normal operation of the limiting device 4 on the receiving platform 9. At the same time, the rotating guide plate 7 is overlapped on the guide platform 12 again, and then the second The screw motor 6 drives the pushing device 3 to move forward. At this time, the position of the scraper 307 is adjusted by the multi-stage telescopic push rod 303, so that the scraper 307 can scrape and brush the upper surface of the material receiving platform 9, the upper surface of the rotating guide plate 7 and the upper surface of the material guide platform 12 in turn, thereby removing the debris on the material receiving platform 9, the rotating guide plate 7 and the material guide platform 12. After the scraping is completed, the pushing device 3 returns to the top of the material receiving platform 9 and waits for the next round of work. At the same time, the limiting device 4 located on the material guide platform 12 returns to the working state again.
