Description

Technical Field

[0001] This utility model relates to the field of plastic bag processing technology, and in particular to an online processing device for sealing strips used in bag making. Background Technology

[0002] To enable reusable opening, many bags have a sealing strip at the opening. However, during bag manufacturing, the sealing strip is installed before cutting. This cutting process can cause burrs on the sealing strip's ends, and even result in uneven edges, affecting the bag's appearance and the sealing performance. Furthermore, while the sealing strip is closed when connected to the bag, it needs to be opened during subsequent filling, impacting production capacity.

[0003] Therefore, there is a need to research a sealing strip processing device that can reinforce and open the sealing strip online. Utility Model Content

[0004] The purpose of this invention is to provide an online processing device for sealing strips used in bag making, which can improve production capacity and welding effect of sealing strips.

[0005] To achieve the above-mentioned utility model objectives, this utility model provides an online processing device for sealing strips used in bag making, including a frame, a transmission roller group, a strip opening plate, a spot welding structure, and a sensing and positioning mechanism;

[0006] The transmission roller group, the slitting plate, the spot welding structure, and the sensing positioning mechanism are arranged sequentially on the frame, with the slitting plate located between the transmission roller group and the spot welding structure.

[0007] The slitting plate is provided with a slitting rod, the side of which is an inclined side facing the conveyor roller group;

[0008] The spot welding structure includes a connecting plate, a pressure plate, a mounting plate, a cylinder, and an ultrasonic welding machine. The connecting plate is connected to the side of the frame, the pressure plate is located on the connecting plate, the pressure plate has a through window, the welding head of the ultrasonic welding machine is located directly above the through window, and the ultrasonic welding machine is connected to the cylinder through the mounting plate.

[0009] The frame is provided with a connecting beam, and the sensing and positioning mechanism includes a camera and a mounting bracket. The mounting bracket is provided with a sensing port, which is located directly below the camera. The mounting bracket is connected to the connecting beam.

[0010] As a further improvement of the utility model, the slatted plate is provided with a plurality of mounting holes, and the first fastener detachably connects the slatted plate to the connecting plate through the mounting holes.

[0011] As a further improvement of the utility model, a driven plate is provided between the ultrasonic welding machine and the cylinder, and a guide rod is connected between the driven plate and the mounting plate.

[0012] As a further improvement of the utility model, the spot welding structure also includes an adjusting screw, and the connecting plate is connected to the frame through the adjusting screw.

[0013] As a further improvement to the utility model, a protective cloth is provided at the bottom of the mounting bracket.

[0014] As a further improvement of the utility model, the mounting bracket is detachably connected to the connecting beam by a second fastener, the end of which abuts against the connecting beam.

[0015] This utility model discloses an online processing device for sealing strips in bag making. The transmission roller group is a combination of two existing upper and lower transmission rollers. The transmission rollers are driven by a motor to rotate, thereby realizing the transmission of the bag body. The bag body with processed sealing strips is transmitted from the transmission roller group. The bag body is transmitted between the pressure plate and the connecting plate. Before spot welding, since the sealing strip is in a closed state during bag making, the opening rod is inserted into the opening of the bag body. As the bag body is transmitted, the opening rod pulls open the sealing strip at the opening of the bag body, which facilitates the subsequent filling of the bag body. The welding head of the ultrasonic welding machine is raised and lowered at a certain frequency by a cylinder. The welding head performs spot welding on both ends of the sealing strip through a through window, which facilitates the subsequent cutting of the bag body. The camera is an existing optical camera. The optical camera identifies the cursor or target image of the bag body below, and then transmits the cursor or image information to the terminal. The terminal sends a signal to the motor of the transmission roller group according to the signal, thereby controlling the transmission speed of the bag body and adapting it to the operation program of the cylinder, so as to cooperate with the spot welding of the sealing strip and achieve precise positioning of the spot welding.

[0016] The advantages of this online processing device for sealing strips used in bag making compared with the prior art are as follows:

[0017] (1) The pressure plate positions the bag body to prevent the upper film of the bag body from lifting up when spot welding the sealing strip, which would affect the welding quality;

[0018] (2) Before the bag body is cut, the sealing strip at the opening of the bag body is opened and spot welded in sequence to open the sealing strip to facilitate subsequent filling. Spot welding at both ends of the sealing strip can strengthen the end of the sealing strip and prevent damage to the end structure of the sealing strip when the bag body is cut.

[0029] This utility model discloses an online processing device for sealing strips in bag making. The transmission roller group 2 is a combination of two existing upper and lower transmission rollers. The transmission rollers are driven by a motor to rotate, thereby realizing the transmission of the bag body. The bag body 6 with the processed sealing strip is transmitted from the transmission roller group 2. The bag body 6 is transmitted between the pressure plate 42 and the connecting plate 41. Before spot welding, since the sealing strip 61 is in a closed state during bag making, the opening rod 31 is inserted into the opening of the bag body 6. Figure 4As shown, as the bag 6 is conveyed, the opening rod 31 pulls open the sealing strip 61 at the opening of the bag 6, facilitating subsequent filling of the bag 6; the welding head of the ultrasonic welding machine 45 is raised and lowered at a certain frequency by the cylinder 44, and the welding head performs spot welding on both ends of the sealing strip 61 through the through window 421, facilitating subsequent cutting of the bag; the camera 51 is an existing optical camera, which identifies the cursor or target image of the bag below, and then transmits the cursor or image information to the terminal. The terminal sends a signal to the motor 21 of the conveying roller group 2 according to the signal, thereby controlling the conveying speed of the bag 6 and matching the operation program of the cylinder 44, so as to cooperate with the spot welding of the sealing strip 61 and achieve precise positioning of the spot welding.

[0030] The slit plate 3 is provided with several mounting holes 31. The first fastener 34 is detachably connected to the connecting plate 41 through the mounting holes 31. According to the position of different bag sealing strips, the slit position of the slit rod 31 can be adjusted by selecting different mounting holes 31 to ensure that the slit rod 31 is always kept in the appropriate slit position.

[0031] A driven plate 48 is provided between the ultrasonic welding machine 45 and the cylinder 44. A guide rod 46 is connected between the driven plate 48 and the mounting plate 43. The guide rod 46 guides the lifting and lowering of the welding head of the ultrasonic welding machine 45, preventing the welding head from being misaligned and affecting the accuracy of the spot welding position.

[0032] The spot welding structure 4 also includes an adjusting screw 47, and the connecting plate 41 is connected to the frame 1 via the adjusting screw 47. Depending on the width of the film, the lateral position of the welding head can be adjusted by turning the adjusting screw 47 to accommodate spot welding of bags of different sizes.

[0033] Mounting bracket 52 serves both as a connection to camera 51 and as a positioning device for the film, preventing the film from warping and affecting the recognition of camera 51. The bottom of mounting bracket 52 is provided with protective cloth 54, which directly contacts the surface of the film instead of the bracket body, preventing the surface of the film from being scratched.
