Description

Technical Field

[0001] This utility model relates to the field of nonwoven bag making machine technology, and in particular to an automated feeding module for a bag making machine. Background Technology

[0002] With the rapid development of the modern packaging industry, bag making machines, as the core equipment for producing various plastic and non-woven packaging bags, directly affect product quality and corporate benefits in terms of their automation level and production efficiency. In the bag making process, the feeding module is a key component, mainly responsible for the stable unwinding and conveying of the roll material. Its performance directly affects the accuracy and continuity of subsequent cutting, sealing and other processes.

[0003] Currently, although some automated feeding modules for bag making machines have appeared on the market, these modules have obvious shortcomings in adapting to non-woven fabric rolls of different widths. The structural design of many feeding modules is relatively fixed, and the positional relationship between the roll support shaft and the frame cannot be flexibly adjusted. When it is necessary to change non-woven fabric rolls of different widths, a complicated disassembly and reinstallation process is often required, which consumes a lot of time and manpower and seriously affects production efficiency. Therefore, it is necessary to design an automated feeding module for bag making machines. Utility Model Content

[0004] The purpose of this invention is to provide an automated feeding module for a bag-making machine to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An automated feeding module for a bag making machine includes:

[0007] A frame, wherein a crossbeam is fixedly installed at the bottom end of the frame, and a crossbar is fixedly installed on the front side of the crossbeam;

[0008] Adjustment mechanisms are provided on both sides of the front end of the frame;

[0009] A connecting mechanism is provided at the bottom of the adjusting mechanism. The connecting mechanism includes a first connecting unit and a second connecting unit. The first connecting unit is provided at the front left end of the frame, and its two ends are respectively rotatably connected to a crossbar and an adjusting mechanism located at the left end of the frame. The second connecting unit is provided at the front right end of the frame, and its two ends are respectively rotatably connected to a crossbar and an adjusting mechanism located at the right end of the frame. The first connecting unit and the second connecting unit are provided with the same round rod on their respective sides that are close to each other.

[0010] A braking mechanism is provided on the first connecting unit, and the braking mechanism is used to prevent the rotation of the round rod.

[0011] By adopting the above technical solution, the non-woven fabric roll is attached to the cylinder. By adjusting the extension length of the adjustment mechanism, and then changing the positional relationship between the cylindrical rod and the frame through the connecting mechanism, the device can adapt to non-woven fabric rolls of different widths and sizes, thereby meeting different feeding effects.

[0012] In a further embodiment, the adjustment mechanism includes:

[0013] The cylinder includes a fixed part and a movable part. The movable part of the cylinder is located at the bottom end of the cylinder body. The top of the cylinder is provided with a first ear plate and a second ear plate at intervals. The first ear plate and the second ear plate are rotatably connected to the front end of the frame. A first locking bolt is provided at the connection between the first ear plate, the second ear plate and the frame. The first locking bolt is used to fix the first ear plate and the second ear plate on the frame.

[0014] The connector is fixedly installed at the bottom of the cylinder, with its opening facing downwards, and is rotatably connected to the first connecting unit / second connecting unit.

[0015] In a further embodiment, the first connection unit and the second connection unit have the same structure, and the first connection unit includes:

[0016] A connecting plate is provided at intervals from front to back on the front side of the frame. The end of the connecting plate near the frame is rotatably connected to the crossbar. The top of the connecting plate extends with an upward protrusion that passes through the opening of the joint.

[0017] The bearing has a downward-facing receiving groove at the top front end of the connecting plate. The left and right sides of the receiving groove are completely open. The rear side of the receiving groove has a rearward-facing arc-shaped groove. The bearing is installed in the arc-shaped groove, and one end of the round rod passes through the bearing.

[0018] A rotating handle is rotatably mounted on the end of the connecting plate away from the frame. A second locking bolt is provided at the connection between the rotating handle and the connecting plate to fix the rotating handle to the connecting plate.

[0019] By adopting the above technical solution, by adjusting the extension and retraction length of the cylinder's movable part, the connecting plate can rotate clockwise or counterclockwise around the crossbar within a certain range, thereby causing the round bar to move closer to or further away from the frame. The bearing is engaged in the arc groove. By rotating the rotating handle, the end face of the rotating handle near the bearing is tightly fitted with the bearing. Then, the rotating handle is locked onto the connecting plate by the third locking bolt, so that the rotating handle cannot be rotated, thereby locking the bearing onto the connecting plate.

[0020] In a further embodiment, the braking mechanism includes a brake, a main gear, and a driven gear. The brake is fixedly installed on the left side of the connecting plate of the first connecting unit. The main gear and the driven gear are spaced apart on the right side of the connecting plate of the first connecting unit. The output shaft of the brake passes through and extends to the right side of the connecting plate. The main gear is sleeved on the right end of the output shaft of the brake, and the driven gear is sleeved on the left end of the round rod. The main gear and the driven gear mesh.

[0021] By adopting the above technical solution, since the bearing is locked inside the connecting plate, when the nonwoven fabric roll is pulled by external force, the round rod will also rotate. At this time, the output shaft of the brake will briefly stop the main gear from rotating. Because the main gear and the driven gear are meshed, the driven gear will also stop rotating, thereby driving the round rod to stop rotating, providing a short processing time for the subsequent welding work of the nonwoven fabric.

[0022] In a further embodiment, a plurality of anti-slip strips are fixedly installed on the surface of the round rod.

[0023] By adopting the above technical solution, the anti-slip strip can increase the friction between the round rod and the inner wall of the non-woven fabric roll.

[0024] In a further embodiment, a control cabinet is fixedly mounted on one side of the rack.

[0025] By adopting the above technical solution, operators can adjust the cylinder extension and retraction amount, braking mechanism parameters, etc. in a timely manner through the control cabinet to ensure that the feeding module always operates stably and to guarantee the efficient production of the bag making machine.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. By attaching the nonwoven fabric roll to the cylinder, adjusting the telescopic length of the adjustment mechanism, and then changing the positional relationship between the cylindrical rod and the frame through the connecting mechanism, this device can adapt to nonwoven fabric rolls of different widths and sizes, and can meet the feeding effect of different nonwoven fabric rolls.

[0037] The braking mechanism 7 includes a brake 71, a main gear 72, and a driven gear 73.

[0038] Specific implementation process: Before starting work, the operator needs to adjust the feeding module according to the width of the non-woven fabric roll to be processed. The frame serves as the supporting structure for the entire module, with a crossbeam 2 fixedly installed at its bottom and a crossbar 3 fixedly installed on the front side of the crossbeam. Adjustment mechanisms 4 are set on both sides of the front end of the frame 1. The cylinder 41 of each adjustment mechanism 4 is rotatably connected to the front end of the top of the frame 1 through the first ear plate and the second ear plate, and is fixed by the first locking bolt. The connector 42 at the bottom of the cylinder 41 will drive the connecting mechanism 5 connected to it to rotate. The extension and retraction of the cylinder 41 will drive the connecting mechanism 5 to move, and the connecting mechanism 5 will be adjusted to... To accommodate the roll width, the connecting mechanism 5 includes a first connecting unit 51 and a second connecting unit 52, both with identical structures. Taking the first connecting unit 51 as an example, the end of the connecting plate 511 closest to the frame 1 is rotatably connected to the crossbar 3, and its top protrusion passes through the opening of the connector 42. When the movable part of the cylinder 41 extends or retracts, the connecting plate 511 rotates clockwise or counterclockwise around the crossbar 3, thereby changing the distance between the round rod 6 and the frame 1. The operator adjusts the cylinders 41 on both sides according to the roll width of the nonwoven fabric to move the round rod 6 to a suitable position to fit the roll. Afterward, the end of the connecting plate 511 away from the frame 1 is rotated. Rotate the handle 513 until it is close to the end face of the bearing 512 and fits tightly against the bearing 512. Then, use the second locking bolt to fix the handle 513 to the connecting plate 511, thereby locking the bearing 512 in the arc groove of the connecting plate 511 and ensuring the stability of the round rod 6. The multiple anti-slip strips installed on the surface of the round rod 6 can increase the friction with the inner wall of the nonwoven fabric roll and prevent the roll from slipping. After completing the above adjustments, put the nonwoven fabric roll onto the round rod 6. At this time, start the equipment, and the braking mechanism 7 begins to work. The brake 71 is fixed on the left side of the connecting plate 511 of the first connecting unit 51. The output shaft of 1 passes through the connecting plate 511. The main gear 72 is installed at the right end of the output shaft, and the driven gear 73 is sleeved at the left end of the round rod 6. The main gear 72 and the driven gear 73 mesh. When the nonwoven fabric roll is pulled by an external force, the round rod 6 rotates. The output shaft of the brake 71 will briefly stop the main gear 72 from rotating. Since the main gear 72 and the driven gear 73 are meshed, the driven gear 73 also stops, thereby causing the round rod 6 to stop rotating briefly, providing processing time for subsequent welding and other work on the nonwoven fabric. After that, the equipment continuously and stably pulls the nonwoven fabric out of the roll and conveys it to the next process of the bag making machine according to the preset program.
