Description

Technical Field

[0001] This utility model relates to the field of plastic bag processing technology, and in particular to a limiting mechanism for plastic bag production. Background Technology

[0002] Plastic bag production is an important industrial process widely used in packaging, shopping, and storage. It mainly includes multiple steps such as plastic material selection, extrusion molding, die cutting, printing, and cutting, with the aim of producing plastic bags with specific sizes, thicknesses, and properties.

[0003] However, traditional methods typically use movable horizontal fixed baffles to restrict the plastic bag material. This can easily cause the plastic bag material to be squeezed and embedded in the gap between the fixed baffle and the conveyor belt, thus affecting the safety of the device when processing the plastic bag material.

[0004] Therefore, those skilled in the art have provided a limiting mechanism for plastic bag production to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a limiting mechanism for plastic bag production. This device is equipped with a positioning mechanism, allowing the user to loosen the fixed slider in the fixed groove by rotating the locking screw, thereby adjusting the position of the gear on the take-up roller. This enables the user to limit the plastic bag to move away from the device by adjusting the distance between the baffles. Precise gear and limiting control helps maintain the consistency and neatness of the plastic bags, thus improving the accuracy of the limiting.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A limiting mechanism for plastic bag production includes a support frame. A flipping mechanism is provided on the upper surface of the support frame. The flipping mechanism includes a rotating shaft. A first servo motor is fixedly connected to one side inside the rotating shaft. Multiple support plates are fixedly connected to both sides of the outer wall of the rotating shaft. A lower mounting ring is fixedly connected to the outer wall of the support plate on the side away from the rotating shaft. An upper mounting ring is provided on the upper surface of the lower mounting ring.

[0008] The outer wall of the flipping mechanism is provided with multiple positioning mechanisms, each including a limiting roller. A limiting plate is engaged with one side of the outer wall of the limiting roller. Multiple fixed grooves are formed on the outer wall of the limiting roller. Baffles are slidably connected to both sides of the middle part of the outer wall of the limiting roller. Locking screws are rotatably connected to the four sides of the outer wall of the baffle. A guide groove is formed at the center of one side of the outer wall of the baffle. Limiting grooves are formed around the four sides of the inner wall of the guide groove. Fixed sliders are slidably connected to the inner wall of the limiting groove.

[0009] Through the above technical solution, the device is equipped with a flipping mechanism, which can adjust the position of multiple limit rollers under the action of the first servo motor. This allows the device to be adjusted quickly according to the width of the plastic bag raw material being processed, thereby expanding the applicability of the device and improving its ease of use.

[0010] Furthermore, the rotating shaft is rotatably connected to the upper end of the inner wall of the support frame, and the output end of the first servo motor is fixedly connected to the support frame;

[0011] Through the above technical solution, the first servo motor can control the rotating shaft to adjust the rotation at a fixed angle.

[0012] Furthermore, a fixing seat is fixedly connected to the upper end of the outer wall of the support plate on one side, a second servo motor is fixedly connected to the upper surface of the fixing seat, and a positioning block is fixedly connected to the output end of the second servo motor.

[0013] The above technical solution enables the second servo motor to control the rotation of the limit roller through the positioning block.

[0014] Furthermore, the limiting roller is rotatably connected to the middle of the upper surface of the lower mounting ring, and a connecting block is fixedly connected to the center of the outer wall of one side of the limiting plate, and a rotating component is rotatably connected to the outer wall of the connecting block;

[0015] The above technical solution enables the limiting roller to be installed between the upper mounting ring and the lower mounting ring via a rotating component.

[0016] Furthermore, the fixed slider slides inside the fixed groove, and the locking screw is threadedly engaged with the fixed slider;

[0017] The above technical solution enables users to rotate the locking screw with tools, thereby moving the position of the fixed slider.

[0018] Furthermore, a positioning block is fixedly connected to the outer wall of the limiting roller on the side away from the limiting plate, and a positioning groove is formed on the upper surface of the positioning block;

[0019] Through the above technical solution, the limiting roller can be connected to the second servo motor through the positioning block and positioning slot, thereby enabling the second servo motor to drive the limiting roller to assist the movement of the plastic bag raw material.

[0020] Furthermore, a mounting slot is provided in the middle of the outer wall of one side of the limiting roller, and a mounting block is fixedly connected to the outer wall of the limiting plate on the side away from the connecting block;

[0021] The above technical solution uses the snap-fit ​​between the mounting slot and the mounting block to install and fix the limiting plate on the limiting roller, thereby limiting the baffle.

[0022] This utility model has the following beneficial effects:

[0023] 1. The present invention proposes a limiting mechanism for plastic bag production. Compared with traditional limiting mechanisms for plastic bag production, this device is equipped with a positioning mechanism. The user can loosen the fixed slider in the fixed groove by rotating the locking screw, thereby adjusting the position of the gear on the take-up roller. This allows the user to limit the plastic bag to move away from the device by adjusting the distance between the baffles. Precise gear and limiting control helps maintain the consistency and neatness of the plastic bags, thereby improving the accuracy of the limiting.

[0024] 2. The present invention proposes a limiting mechanism for plastic bag production. Compared with most traditional automatic plastic bag bundling devices, this device is equipped with a flipping mechanism. Under the action of a first servo motor, it can adjust the position of multiple limiting rollers, thereby enabling the device to be adjusted more quickly according to the width of the plastic bag raw material being processed. This improves the applicability of the device and enhances its ease of use. Attached Figure Description

Limiting grooves 309 are opened around the four sides of the inner wall of the guide groove 308. Fixed sliders 3010 are slidably connected to the inner wall of the limiting grooves 309. The device is provided with a flipping mechanism 2. Under the action of the first servo motor 202, the multiple limiting rollers 301 can be adjusted, so that the device can be adjusted quickly according to the width of the plastic bag raw material being processed, thereby improving the applicability of the device and the convenience of its use.

[0040] Reference Figure 2 , 3 5. The rotating shaft 201 is rotatably connected to the upper end of the inner wall of the support frame 1. The output end of the first servo motor 202 is fixedly connected to the support frame 1, so that the first servo motor 202 can control the rotating shaft 201 to rotate at a fixed angle. A fixed seat 206 is fixedly connected to the upper end of the outer wall of the support plate 203 on one side. A second servo motor 207 is fixedly connected to the upper surface of the fixed seat 206. A positioning block 208 is fixedly connected to the output end of the second servo motor 207, so that the second servo motor 207 can control the limiting roller 301 to rotate through the positioning block 208.

A connecting block 303 is fixedly connected to the center of the outer wall of one side of the limiting plate 302. A rotating part 304 is rotatably connected to the outer wall of the connecting block 303, so that the limiting roller 301 can be installed between the upper mounting ring 205 and the lower mounting ring 204 through the rotating part 304.

The locking screw 307 is threadedly engaged with the fixed slider 3010, so that the user can rotate the locking screw 307 with a tool to move the position of the fixed slider 3010.

[0043] Working principle: First, rotating the locking screw 307 loosens the restriction on the fixed slider 3010, thereby loosening the compression between the fixed slider 3010 and the fixed slide groove 305. This allows the device to adjust the distance between the baffles 306 according to the width of the plastic bag material (long strip of material to be cut). After adjustment, tightening the locking screw 307 completes the compression between the fixed slider 3010 and the fixed slide groove 305 to restrict the position of the baffles 306. Similarly, the distance between the baffles 306 on the other two limiting rollers 301 is adjusted to the corresponding distance according to the width of the plastic bag material. The second servo motor 207 can assist in the material conveying. The first servo motor 202 can flip the limiting rollers 301 to quickly complete the adjustment of the limiting rollers 301 for plastic bag materials of different widths. Finally, the user can remove the upper mounting ring 205 and the limiting plate 302 to disassemble and replace the damaged limiting rollers 301 or baffles 306.
