Description

Technical Field

[0001] This solution belongs to the technical field of feeding devices, specifically relating to a feeding device for printing food packaging bags. Background Technology

[0002] Utility model patent CN222453602U discloses a conveying device for printing plastic bags, relating to the field of transportation device technology. This utility model includes a frame with a conveyor belt in the middle. A drive mechanism for controlling the rotation of the conveyor belt is mounted on the surface of the frame. A screen printing machine body is fixedly mounted on the back of the frame. A pressing component for pressing the plastic bags is mounted on the top surface of the frame. A positioning component for adjusting the position of the pressing component is also provided on the top surface of the frame. An attachment component is longitudinally inserted through the front side wall of the frame. The drive mechanism includes a motor, which is fixedly mounted on the front of the frame. The output shaft of the motor is fixedly connected to a drive roller. In use, this device facilitates continuous conveying and printing of plastic bags, effectively limits the movement of the plastic bags, and prevents the plastic bags from sticking to the screen, thus ensuring the normal printing process.

[0003] However, the device has certain shortcomings in use. If the packaging bag becomes loose during the transportation process, it will cause the printed pattern to be distorted. At the same time, the device is not convenient for guiding the movement of the packaging bag. Utility Model Content

[0004] The purpose of this solution is to provide a feeding device for printing on food packaging bags, which solves the problem that loosening of the packaging bags during transport can lead to distortion of the printed patterns, and that the device is not convenient for guiding the movement of the packaging bags.

[0005] To achieve the above objectives, this solution provides a feeding device for printing food packaging bags, including a frame, a support roller rotatably connected inside the frame, a conveyor belt mounted on the support roller, a motor fixedly mounted at the front end of the frame, the motor's shaft passing through the frame and rotatably connected to the frame, a bracket fixedly mounted at the upper end of the frame, a feeding mechanism mounted on the bracket, and a guiding mechanism mounted on the bracket.

[0006] The principle of this solution is as follows: Using the packaging bag width adjustment device, manually rotating the bidirectional screw causes the pressure plate to move, compressing the spring. The spring's elasticity moves the slide, bringing the limiting plate into contact with the side of the packaging bag. This guides the movement of the packaging bag, preventing positional deviation. The motor then drives the support roller to rotate, which in turn drives the conveyor belt. The conveyor belt moves the packaging bag. During this process, the spring acts on the guide rod, causing the support frame to move the pressure roller. This ensures that during printing, the pressure roller flattens the packaging bag on the conveyor belt, preventing misalignment of the printed patterns.

[0007] The technical effect of this solution is that the spring acts on the guide rod, which in turn causes the support frame to move the pressure roller. This allows the pressure roller to flatten the packaging bag on the conveyor belt during the printing process, thus making it less likely for the printed patterns on the packaging bag to become disordered.

[0008] By rotating the bidirectional screw and pressure plate to make a spiral motion, the compression spring elastically drives the slide to move, which in turn causes the limiting plate to contact the side of the packaging bag, thus guiding the movement of the packaging process and preventing the packaging bag from shifting position during movement.

[0009] Furthermore, the feeding mechanism includes a guide cylinder, which is fixedly installed on the top inner side of the bracket. A guide rod is slidably connected inside the guide cylinder, and a spring is installed inside the guide cylinder. A support frame is fixedly connected to the lower end of the guide rod, and a pressure roller is rotatably connected inside the support frame. The pressure roller contacts the conveyor belt. A brush roller is installed inside the support frame and contacts the conveyor belt. A liquid inlet pipe is installed on the brush roller and is fixedly connected to the bracket. The spring acts on the guide rod, causing the support frame to move the pressure roller. This allows the pressure roller to flatten the packaging bag on the conveyor belt during printing, preventing the printed patterns on the packaging bag from becoming misaligned.

[0010] Furthermore, one end of the spring is fixedly connected to the bracket, and the other end of the spring is fixedly connected to the guide rod. By setting the spring, the guide rod is elastically pressed down.

[0011] Furthermore, the guiding mechanism includes a slide, which is slidably connected inside the bracket. A bidirectional screw is movably connected inside the slide, and a pressure plate is threadedly connected to the outer side of the bidirectional screw. The pressure plate is slidably connected to the bracket, and a compression spring is provided on the outer side of the bidirectional screw. By rotating the bidirectional screw and the pressure plate to perform threaded movement, the compression spring elastically drives the slide to move, thereby causing the limiting plate to contact the side of the packaging bag. This guides the movement of the packaging process and prevents positional deviation of the packaging bag during movement.

[0012] Furthermore, a limiting plate is fixedly connected to the lower end of the carriage, and the limiting plate is slidably connected to the conveyor belt. The limiting plate guides the movement of the packaging bag.

[0013] Furthermore, a limiting block is fixedly connected to the upper end of the bracket, and the limiting block is slidably connected to the bidirectional screw. By setting the limiting block, the bidirectional screw is prevented from moving out of control.

[0014] Furthermore, one end of the compression spring is fixedly connected to the pressure plate, and the other end of the compression spring is fixedly connected to the slide. By setting the compression spring, the slide is elastically compressed. Attached Figure Description

[0021] The implementation examples are basically as follows Figure 1 As shown, this embodiment provides a feeding device for printing food packaging bags, including a frame 1, a support roller 2 rotatably connected inside the frame 1, a conveyor belt 3 provided on the support roller 2, a motor 4 fixedly installed at the front end of the frame 1, the rotating shaft of the motor 4 passing through the frame 1 and rotatably connected to the frame 1, a bracket 5 fixedly installed at the upper end of the frame 1, a feeding mechanism 6 provided on the bracket 5, and a guiding mechanism 7 provided on the bracket 5.

[0022] like Figure 1 , Figure 2 , Figure 3 The feeding mechanism 6 includes a guide cylinder 61. The guide cylinder 61 is fixedly installed on the top inner side of the bracket 5. A guide rod 62 is slidably connected inside the guide cylinder 61. A spring 63 is installed inside the guide cylinder 61. One end of the spring 63 is fixedly connected to the bracket 5, and the other end of the spring 63 is fixedly connected to the guide rod 62. By setting the spring 63, the guide rod 62 is elastically pressed down. A support frame 64 is fixedly connected to the lower end of the guide rod 62. A pressure roller 65 is rotatably connected inside the support frame 64. The pressure roller 65 is in contact with the conveyor belt 3. A brush roller 66 is installed inside the support frame 64. The brush roller 66 is in contact with the conveyor belt 3. An inlet pipe 67 is set on the brush roller 66. The inlet pipe 67 is fixedly connected to the bracket 5. By the action of the spring 63 on the guide rod 62, the support frame 64 drives the pressure roller 65 to move. Thus, during the printing process, the pressure roller 65 can flatten the packaging bag on the conveyor belt 3, thereby making the printed pattern on the packaging bag less likely to be disordered.

[0023] like Figure 1 , Figure 4 The guiding mechanism 7 includes a carriage 71, which is slidably connected inside the support 5. A limit plate 72 is fixedly connected to the lower end of the carriage 71. The limit plate 72 is slidably connected to the conveyor belt 3. By setting the limit plate 72, the movement of the packaging bag is guided. A bidirectional screw 73 is movably connected inside the carriage 71. A limit block 74 is fixedly connected to the upper end of the support 5. The limit block 74 is slidably connected to the bidirectional screw 73. By setting the limit block 74, the bidirectional screw 73 is prevented from moving. A pressure plate 75 is threadedly connected to the outer side of the bidirectional screw 73. Plate 75 and bracket 5 are slidably connected. A compression spring 76 is provided on the outside of the bidirectional screw 73. One end of the compression spring 76 is fixedly connected to the pressure plate 75, and the other end of the compression spring 76 is fixedly connected to the slide 71. By setting the compression spring 76, the slide 71 is elastically compressed. By rotating the bidirectional screw 73 and the pressure plate 75 to make threaded movement, the compression spring 76 elastically drives the slide 71 to move, thereby making the limiting plate 72 contact the side of the packaging bag, thus guiding the movement of the packaging process and preventing the packaging bag from shifting position during movement.

[0024] The specific implementation process of this utility model is as follows: According to the packaging bag width adjustment device, the bidirectional screw 73 is manually rotated. The bidirectional screw 73 rotates and the pressure plate 75 makes a threaded movement, thereby causing the pressure plate 75 to move. The pressure plate 75 squeezes the compression spring 76, and the compression spring 76 elastically drives the slide 71 to move, thereby causing the limiting plate 72 to contact the side of the packaging bag, thus guiding the movement of the packaging process and preventing the packaging bag from shifting position during movement. The motor 4 is started, and the motor 4 drives the support roller 2 to rotate. The support roller 2 drives the conveyor belt 3 to rotate, and the conveyor belt 3 drives the packaging bag to move. During this process, the spring 63 acts on the guide rod 62, thereby causing the support frame 64 to drive the pressure roller 65 to move. Thus, during the printing process, the pressure roller 65 can flatten the packaging bag on the conveyor belt 3, thereby making the printed pattern on the packaging bag less likely to be disordered.

[0025] The spring 63 acts on the guide rod 62, which in turn causes the support frame 64 to move the pressure roller 65. As a result, during the printing process, the pressure roller 65 can flatten the packaging bag on the conveyor belt 3, thus making it less likely for the printed patterns on the packaging bag to become disordered.

[0026] By rotating the bidirectional screw 73 and the pressure plate 75 to make threaded movements, the compression spring 76 elastically drives the slide 71 to move, which in turn causes the limiting plate 72 to contact the side of the packaging bag, thereby guiding the movement of the packaging process and preventing the packaging bag from shifting position during movement.
