AI Technical Summary
Traditional bag feeding components have complex structures, are difficult to install and maintain, are prone to wear, have insufficient friction causing the packaging bags to slip, have poor compatibility, and are difficult to meet diverse production needs.
It adopts a closed-loop stepper motor to drive the polyurethane-coated shaft and the hardened knurled shaft, combined with a synchronous belt drive system and auxiliary devices. The wear-resistant material of the polyurethane-coated shaft and the surface treatment of the hardened knurled shaft enhance the friction, and the hook spring provides continuous clamping force, combined with modular design and adaptive adjustment function.
It achieves high-precision, low-noise, and anti-slip conveying of packaging bags, is compatible with various materials, reduces maintenance difficulty and noise, and improves the reliability and applicability of the equipment.

Abstract
Claims
1. An anti-slip bag feeding mechanism, characterized in that: The device includes a closed-loop stepper motor (8), a polyurethane-coated shaft (1), a hardened knurled shaft (2), a cam (3), a balance ring, a hook spring (9), a timing belt (7), a timing pulley (5), a bearing, a stabilizing sheet metal (6), a handle (10), a mounting plate (11), and a hexagonal column (12). The cylinder of the closed-loop stepper motor (8) is fixed to the device by a pair of mounting plates (11). The output end of the closed-loop stepper motor (8) is fixedly provided with a timing pulley (5). The timing pulley (5) and the timing belt (7) cooperate to transmit power to the polyurethane-coated shaft (1). The polyurethane-coated shaft (1) is rotatably connected to the mounting plate (11) through a bearing. The two ends of the hardened knurled shaft (2) are respectively fitted with a cam (3) and a balance ring. The end of the hook spring (9) on the balance ring is connected to the hexagonal column (12) fixed on the outer wall of the mounting plate (11).
2. The anti-slip bag delivery mechanism of claim 1, wherein: The surface of the polyurethane-coated shaft (1) is coated with a polyurethane layer to increase friction, and the surface of the hardened knurled shaft (2) is processed by knurling and hardening to enhance surface roughness and hardness.
3. The anti-slip bag delivery mechanism of claim 2, wherein: The bearing is a self-aligning bearing (4) with an adaptive adjustment function to adjust the level of the polyurethane-coated shaft (1) in real time, so as to avoid abnormal noise or jamming caused by uneven force on the shaft during operation.
4. The anti-slip bag delivery mechanism of claim 1, wherein: The bottom of the cam (3) is designed to be horizontal to prevent the balance ring from tilting when the hook spring (9) is tightened. The cam (3) works with the handle (10) to pass the bag through the gap between the hardened knurled shaft (2) and the polyurethane coated shaft (1).
5. The anti-slip bag delivery mechanism of claim 4, wherein: There are four hook springs (9), which are respectively set at both ends of the balance ring. The elastic deformation applies tension to the balance ring so that the hardened knurled shaft (2) always fits tightly against the polyurethane coated shaft (1).
6. The anti-slip bag delivery mechanism of claim 1, wherein: The stabilizing sheet metal (6) has an L-shaped cross section and is fixedly installed on the outer wall of the mounting plate (11). Its top abuts against the cam (3) to support and stabilize the cam (3).
7. The anti-slip bag feeding mechanism as described in claim 1, characterized in that: The bearings include a deep groove ball bearing (14) and a self-aligning ball bearing (13). The bearing on the left mounting plate (11) is a deep groove ball bearing (14), and the bearing on the driven end of the right mounting plate (11) is a self-aligning ball bearing (13). The mounting plate (11) is an aluminum plate.
