Technical Field
[0001] This utility model relates to the field of plastic production technology, and in particular to a discharge device for a plastic packaging bag welding machine. Background Technology
[0002] Plastic packaging bag welding machines are specialized equipment for welding plastic packaging bags. They fuse specific parts of the plastic film through heating, pressurization, or ultrasonic vibration to form strong weld points or weld lines, thus meeting the needs of bag handle installation and sealing.
[0003] When welding the edge of a plastic film, after placing the plastic bag in the corresponding position on the welding machine, the worker can adjust the direction and speed of the welding blade according to the actual position of the plastic bag to accommodate weldments of different sizes.
[0004] However, in the existing technology, novice employees may experience misalignment when placing plastic packaging bags. Furthermore, due to their lack of operational experience, adjustments are required, resulting in a longer time to reach the correct welding position. Consequently, the plastic packaging bags are fed slowly, leading to low welding efficiency.
[0005] Therefore, it is necessary to solve the above problems by using a discharge device for a plastic packaging bag welding machine. Utility Model Content
[0006] The purpose of this utility model is to provide a material discharge device for a plastic packaging bag welding machine to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a discharge device for a plastic packaging bag welding machine, comprising a machine body, an adsorption component and a moving component inside the machine body, a plastic bag placed on the adsorption component, a welding table and a support column on the top surface of the machine body, a control center on the side of the machine body, a first electric hydraulic cylinder on the support column, a welding knife fixedly connected to the output end of the first electric hydraulic cylinder, a mounting frame on the bottom surface of the first electric hydraulic cylinder, and a camera mounted on the mounting frame.
[0008] Preferably, the moving component includes an adjusting motor, and a rotating shaft is fixedly connected to the output shaft of the adjusting motor.
[0009] Preferably, the moving component further includes a support plate, which is fixedly installed on the inner side of the machine body, and a moving plate is slidably disposed on the support plate, and the adjusting motor is fixedly installed on the moving plate.
[0010] Preferably, a second electric hydraulic cylinder is fixedly installed on the inner side of the machine body below the support plate, and a traction plate is fixedly connected to the output end of the second electric hydraulic cylinder. The traction plate is fixedly installed on the bottom surface of the moving plate.
[0011] Preferably, the adsorption assembly includes a movable disk, on which adsorption tubes are evenly arranged. A flexible tube is fixedly connected to the end of the adsorption tube away from the movable disk, and a suction machine is fixedly connected to the end of the flexible tube away from the adsorption tube. The top end of the rotating shaft is fixedly connected to the movable disk, and the central axis of the rotating shaft coincides with the central axis of the movable disk.
[0012] Preferably, the movable disk is slidably disposed on the top surface of the machine body, and an elliptical through hole is provided on the top surface of the machine body for the movable disk to slide and rotate. One end of the adsorption tube is located above the elliptical through hole, and the other end passes through the elliptical through hole and is fixedly connected to the flexible tube.
[0013] Preferably, the welding knife is located directly above the welding table, and the camera is mounted at an angle on the mounting bracket with its shooting end facing the welding table.
[0014] The technical effects and advantages of this utility model are as follows: 1. In this utility model, a camera is set up to capture real-time images of the positional relationship between the welding table and the plastic bag. The captured image data is transmitted to the control center, which determines whether the plastic bag has moved into place. If it has not moved into place, the adsorption component and the moving component are controlled to adjust the plastic bag so that it can move into place quickly and intelligently. This avoids the need for manual adjustment by the staff and improves the subsequent material feeding speed and welding efficiency.
[0015] 2. In this utility model, by setting and adjusting the motor, rotating shaft, and moving plate, the control center can determine the current deflection angle and the distance to be moved of the plastic bag based on the image data transmitted by the camera. Then, it controls the adjusting motor to drive the plastic bag to rotate through the rotating shaft to correct the angle deflection. Then, it controls the moving plate to quickly move the plastic bag to the welding position. After welding, it moves back to the loading position, thereby quickly completing the loading and unloading. This avoids the problem of low welding efficiency of plastic packaging bags caused by factors such as improper placement by the staff or lack of operating skills, and ensures the welding efficiency of plastic bags.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0019] To address the problem in existing technologies that novice workers may experience misalignment when placing plastic packaging bags, and the time required for adjustments due to unfamiliarity with the operation leads to a longer time to reach the correct welding position, resulting in slow plastic packaging bag feeding speed and low welding efficiency, the following embodiments are proposed.
[0020] This utility model provides, for example Figures 1 to 4 The device shown is a discharge device for a plastic packaging bag welding machine, including a machine body 1. Inside the machine body 1, there is an adsorption component 2 and a moving component 3. A plastic bag 4 is placed on the adsorption component 2. A welding table 5 and a support column 11 are arranged on the top surface of the machine body 1. A control center 6 is arranged on the side of the machine body 1. A first electric hydraulic cylinder 7 is arranged on the support column 11. A welding knife 8 is fixedly connected to the output end of the first electric hydraulic cylinder 7. A mounting frame 9 is arranged on the bottom surface of the first electric hydraulic cylinder 7. A camera 10 is mounted on the mounting frame 9. The welding knife 8 is located directly above the welding table 5. The camera 10 is mounted at an angle on the mounting frame 9, with the shooting end facing the welding table 5.
[0021] When in use, the staff places the plastic bag 4 on the moving plate 201. The camera 10 captures real-time images of the position of the welding table 5 and the plastic bag 4 and transmits them to the control center 6. After receiving the image data, the control center 6 makes a judgment on the difference between the current position of the plastic bag 4 and the welding table 5 and the actual welding position, such as the deflection angle and the distance that needs to be moved.
[0022] Camera 10 is set up to capture real-time images of the positional relationship between welding station 5 and plastic bag 4. The captured image data is transmitted to control center 6. Control center 6 determines whether plastic bag 4 has moved into place. If it has not moved into place, it controls adsorption component 2 and moving component 3 to adjust plastic bag 4 so that it can move into place quickly and intelligently, thereby avoiding the need for manual adjustment by staff and improving the subsequent material feeding speed and welding efficiency.
[0023] like Figure 3 As shown, the adsorption assembly 2 includes a movable disk 201, on which adsorption tubes 202 are evenly arranged. A flexible tube 203 is fixedly connected to one end of the adsorption tube 202 away from the movable disk 201. The flexible tube 203 is long enough to be unaffected when the movable disk 201 rotates. A suction machine 204 is fixedly connected to one end of the flexible tube 203 away from the adsorption tube 202. When the suction machine 204 is started, the top of the adsorption tube 202 generates suction, thereby adsorbing and fixing the plastic bag 4. The movable disk 201 is slidably disposed on the top surface of the machine body 1. An elliptical through hole is provided on the top surface of the machine body 1 for the movable disk 201 to slide and rotate. One end of the adsorption tube 202 is located above the elliptical through hole, and the other end passes through the elliptical through hole and is fixedly connected to the flexible tube 203.
[0024] When in use, the control center 6 starts the suction machine 204, and the suction tube 202 generates suction force to fix the plastic bag 4 onto the moving plate 201.
[0025] like Figure 4 As shown, the moving component 3 includes an adjusting motor 301, a rotating shaft 302 fixedly connected to the output shaft of the adjusting motor 301, the top end of the rotating shaft 302 fixedly connected to the moving disk 201, and the central axis of the rotating shaft 302 coinciding with the central axis of the moving disk 201; the moving component 3 also includes a support plate 304, which is fixedly installed on the inner side of the machine body 1, and a moving plate 303 is slidably arranged on the support plate 304, with the adjusting motor 301 fixedly installed on the moving plate 303; a second electric hydraulic cylinder 305 is fixedly installed on the inner side of the machine body 1 below the support plate 304, and a traction plate 306 is fixedly connected to the output end of the second electric hydraulic cylinder 305, with the traction plate 306 fixedly installed on the bottom surface of the moving plate 303.
[0026] When in use, the control center 6 starts the adjustment motor 301 to rotate based on the angle data and distance data of the required deflection. The adjustment motor 301 drives the moving disk 201 to rotate according to the deflection angle through the rotating shaft 302, thereby driving the plastic bag 4 to deflect at the correct angle to ensure that the plastic bag 4 is fed at the correct angle.
[0027] Control center 6 then restarts the second electric hydraulic cylinder 305, controlling its output end to extend, thereby driving the traction plate 306 to move towards the welding table 5. This, in turn, drives the adjusting motor 301 to move towards the welding table 5 via the moving plate 303. The adjusting motor 301 then drives the moving plate 201 and the plastic bag 4 to move towards the welding table 5 for material loading. This continues until the image data captured by camera 10 shows that the plastic bag 4 has moved to the actual welding position. At this point, control center 6 stops the extension of the output end of the second electric hydraulic cylinder 305, completing the material loading process.
[0028] Then, the control center 6 controls the output end of the first electric hydraulic cylinder 7 to extend, driving the welding knife 8 to descend and press onto the plastic bag 4, thereby welding the sealing position of the plastic bag 4.
[0029] After welding is completed, the control center 6 controls the output end of the first electric hydraulic cylinder 7 to retract, driving the welding knife 8 to rise back to its original position. Then, it controls the output end of the second electric hydraulic cylinder 305 to retract, thereby moving the plastic bag 4 away from the welding table 5 through the moving plate 201. Then, the suction machine 204 is turned off, the suction force of the suction tube 202 disappears, and the suction on the plastic bag 4 is canceled, thus completing the unloading.
[0030] By adjusting the motor 301, the rotating shaft 302, and the moving plate 303, the control center 6 can determine the current deflection angle and the distance to be moved of the plastic bag 4 based on the image data transmitted by the camera 10. Then, it controls the motor 301 to drive the plastic bag 4 to rotate through the rotating shaft 302 to correct the angle deflection. Then, it controls the moving plate 303 to quickly move the plastic bag 4 to the welding position. After welding, it moves back to the loading position, thus quickly completing the loading and unloading. This avoids the problem of low welding efficiency of plastic packaging bags caused by factors such as improper placement by the staff or lack of operating skills, and ensures the welding efficiency of the plastic bag 4.
[0031] The working principle of this utility model is as follows: First, the plastic bag 4 to be welded is fixed. The worker places the plastic bag 4 on the moving plate 201, and then starts the suction machine 204 through the control center 6, so that the suction tube 202 generates suction force and fixes the plastic bag 4 on the moving plate 201.
[0032] Secondly, to determine the offset of plastic bag 4, the staff activates camera 10 through control center 6. Camera 10 takes real-time pictures of the positions of welding table 5 and plastic bag 4 and transmits the image data to control center 6. After receiving the image data, control center 6 makes a judgment on the difference between the current position of plastic bag 4 and welding table 5 and the actual welding position, such as the deflection angle and the distance that needs to be moved.
[0033] Then, the plastic bag 4 is adjusted for feeding. Based on the determined angle and distance data, the control center 6 starts the adjustment motor 301. The adjustment motor 301 drives the moving plate 201 to rotate according to the deflection angle via the rotating shaft 302, thereby causing the plastic bag 4 to deflect at the correct angle during feeding. Next, the second electric hydraulic cylinder 305 is activated, controlling its output end to extend, thereby moving the traction plate 306 towards the welding table 5. This, in turn, drives the adjustment motor 301 towards the welding table 5 via the moving plate 303. The adjustment motor 301 then moves the moving plate 201 and the plastic bag 4 towards the welding table 5 for feeding, until the image data captured by the camera 10 shows that the plastic bag 4 has moved to the actual welding position. The control center 6 then stops the extension of the output end of the second electric hydraulic cylinder 305, completing the feeding process.
[0034] Next, the plastic bag 4 is welded. The control center 6 controls the output end of the first electric hydraulic cylinder 7 to extend, driving the welding knife 8 to descend and press onto the plastic bag 4, thereby welding the sealing position of the plastic bag 4.
[0035] Finally, the plastic bag 4 is unloaded. After welding, the control center 6 controls the output end of the first electric hydraulic cylinder 7 to retract, driving the welding knife 8 to rise back to its original position. Then, the output end of the second electric hydraulic cylinder 305 is controlled to retract, thereby moving the plastic bag 4 away from the welding table 5 through the moving plate 201. Then, the suction machine 204 is turned off, the suction force of the suction tube 202 disappears, and the suction on the plastic bag 4 is canceled, thus completing the unloading.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
