Figures 1 to 5 As shown: A continuous automatic feeding and pushing mechanism includes a main support mechanism, a material box lifting mechanism, a material box clamping mechanism, and a material strip pushing mechanism;

[0028] The main support mechanism includes a base plate 5, a left support plate 11, a right support plate 12, a support end bearing seat 41, and a cover plate 43;

[0030] The material box clamping mechanism includes a lead screw motor 22, a motor mounting plate 23, a wide linear guide rail 26, a tensioning drive plate 16, a fixed stop bar A13, a fixed stop bar B14, a side stop bar A18, a side stop bar B17, a front stop bar 15, a rubber pad 31, a spring 36, a rubber-coated bearing 37, a male and female buckle 38, a home stop plate body 40, a home optocoupler 35, a switch bracket 19, and a photoelectric switch 20;

[0032] In this embodiment, the lead screw nut plate 8 is fixed on the slide plate 7, so that the rotation of the ball screw 42 can precisely drive the slide plate 7 to move up and down, ensuring smooth movement and accurate positioning during the lifting and lowering of the material box, while avoiding shaking of the slide plate 7 during high-frequency operation, thus improving the reliability of the entire feeding mechanism.

[0033] In a further preferred embodiment of this utility model, the left support plate 11 and the right support plate 12 are symmetrically arranged on both sides of the base plate 5. The support end bearing seat 41 is fixed on the left support plate 11 and the right support plate 12. The cover plate 43 is arranged between the support plates. The two ends of the ball screw 42 are supported by the fixed bearing seat 4 and the support bearing seat 27 respectively. The coupling 2 connects the stepper motor and the ball screw 42. The motor seat 3 is fixed on the base plate 5. The screw nut plate 8 is fixed on the slide plate 7. The support plate 6 is installed on the slide plate 7.

[0034] In this embodiment, the support end bearing seat 41 is fixed on the left support plate and the right support plate 12, providing a stable support point for the ball screw 42, so that the ball screw 42 remains coaxial when rotating, reducing the influence of eccentric torque on the slide plate 7 and the support plate 6, and improving the motion accuracy and service life of the entire lifting mechanism.

[0035] In a further preferred embodiment of this utility model, the lead screw motor 22 is fixed on the support end bearing seat 41 by the motor mounting plate 23, and the lead screw at its output end is connected to the lead screw nut on the tension drive plate 16. The front stop bar 15 is connected to the rubber-coated bearing 37 by the spring piece 36. The rubber-coated bearing 37 is fitted with a snap fastener 38, and the front stop bar 15 is provided with a rubber pad 31.

[0036] In this embodiment, the lead screw motor 22 is fixed to the support end bearing seat 41 by the motor mounting plate 23, so that the motor and the support structure are firmly connected, ensuring that the rotational motion output by the lead screw can be stably transmitted to the tension drive plate 16, realizing precise linear adjustment of the clamping mechanism. The front stop bar 15 is connected to the rubber-coated bearing 37 by the spring piece 36. The rubber-coated bearing 37 is fitted with a male and female buckle 38. The front stop bar 15 is provided with a rubber pad 31, so that the material bar is subjected to uniform force and buffers the impact during the clamping process, while reducing damage to the surface of the material bar and improving the reliability and service life of the clamping.

[0037] In a further preferred embodiment of this utility model, fixed stop bar A13 and fixed stop bar B14 are respectively fixed on the left support plate 11 and the right support plate 12, side stop bar A18 and side stop bar B17 are respectively fixed on fixed stop bar A13 and fixed stop bar B14, the slide cylinder 21 of the pushing mechanism is mounted on the cylinder mounting plate 24, the cylinder push rod drive plate 28 is connected to the push rod 29, the push rod 29 is connected to the outside of the push rod 30, the position of the push rod 30 is adjustable to adapt to different material strip widths, the photoelectric switch 20 is fixed on the switch bracket 19, the switch bracket 19 is mounted on the fixed stop bar B14, and the origin optocoupler 35 is mounted on the right support plate 12.

[0038] In this embodiment, fixed baffles A13 and B14 are fixed on the left support plate 11 and the right support plate 12, respectively, and side baffles A18 and B17 are fixed on them, forming a double-layer lateral constraint structure. This ensures that the material strip moves in a straight line during the pushing process, preventing deviation or tilting. The slide cylinder 21 is connected to the push rod 29 and the push rod 30 through the cylinder mounting plate 24, so that the pushing force can be smoothly transmitted to the material strip. The position of the push rod 30 is adjustable to adapt to material strips of different widths. At the same time, the photoelectric switch 20 is mounted on the bracket and fixed to the fixed baffle B14 to ensure accurate and reliable positioning detection of the material strip.

[0039] In summary, in the initial state, the material box lifting mechanism and the material box clamping mechanism first return to zero and then to the standby position. At this time, the material box clamping mechanism is in the open state (i.e., the width of the opening is greater than the width of the material box). The manual person places the material box filled with material strips onto the support plate 6 of the lifting mechanism. Then the entire mechanism starts to operate. The material box clamping mechanism moves to the semi-clamped position, and the material box lifting mechanism drives the material box to move downward to the position of the first material strip at the bottom. Then the slide cylinder 21 drives the push rod 30 to the right from the material box. The material strips are ejected and then returned to their original positions. The next process will then pull all the material strips out of the material box for the next operation. The material box lifting mechanism continues to move downwards to the position of the second material strip, while the pushing mechanism continues to eject the material strips, creating a continuous cycle. While the mechanism is running, manual feeding can continue, with a maximum of two material boxes allowed. Because the material boxes are in a semi-compressed state, the width of the material box compression mechanism must be greater than the width of the material box to allow for the insertion of material boxes while maintaining a semi-compressed state. When the bottom layer... After the material strips in the first material box are completely pushed out, the lifting mechanism continues to move downwards, so that the upper surface of the bottom first material box is lower than the lower surface of the front stop bar 15. At this time, the material box clamping mechanism moves to the fully clamped state, so that the material boxes above the bottom are completely clamped and cannot slide downwards. The clamping mechanism continues to move downwards, and the bottom first material box is completely separated from the material box above it. When it is separated to the appropriate position, the material box unloading mechanism used in this mechanism will push the empty bottom material box from the support plate 6 of the lifting mechanism. Then the lifting mechanism moves upwards again. When it moves to the bottom position of the second material box, the material box moves to the semi-clamped state position. The second material box and the material box above it will be caught by the support plate 6 and move with the support plate 6. The support plate 6 continues to support the second material box and moves to the corresponding pushing position in sequence, performing reciprocating cycle operation. In this way, the uninterrupted fully automatic feeding function can be realized. When used for unloading and unloading: at this time, the material strip pushing mechanism is not needed, and the fully automatic uninterrupted loading and unloading operation is performed.In the initial state, the material box lifting mechanism and the material box clamping mechanism first return to zero and then to the standby position. At this time, the material box clamping mechanism is in the open state (i.e., the width of the opening is greater than the width of the material box). The operator places an empty material box onto the support plate 6 of the lifting mechanism, and then the entire mechanism starts to operate. The material box clamping mechanism moves to the semi-clamped position, and the lifting mechanism moves the material box to the bottom first strip feeding position. The strips completed from the previous process will be pushed into the material box. After each strip is pushed, the lifting mechanism continues to move to the next receiving position to wait. When the bottom first material box is full of strips, the lifting mechanism continues to move downward, so that the upper end of the bottom first material box is lower than the lower end of the front stop 15. When the clamping mechanism moves to the fully clamped state, the bottommost and above material boxes are completely clamped and cannot slide downwards. As the clamping mechanism continues to move downwards, the bottommost material box completely separates from the boxes above it. When they are separated to the appropriate position, the material box ejection mechanism, used in conjunction with this mechanism, pushes the empty bottommost material box off the lifting mechanism's support plate 6. The lifting mechanism then moves upwards until it reaches the bottom of the second material box, at which point the box is in a semi-clamped state. The second material box and the boxes above it are then caught by the support plate 6 and move with it. The support plate 6 continues to support the second material box, moving sequentially to the corresponding receiving position, repeating the cycle. This achieves uninterrupted, fully automatic material feeding.
