Description

Technical Field

[0001] This utility model belongs to the field of printing machinery, specifically relating to the paper loosening and splitting blower mechanism in a paper feeder. Background Technology

[0002] Paper feeders are commonly used feeding mechanisms in sheet-fed printing and packaging equipment (such as offset printing presses and laminating machines). The paper feed head is the core component of the paper feeder, and its function is to accurately separate the top sheet of paper from the stack and transport it to the next workstation. The paper loosening blower mechanism in the paper feed head plays a crucial role in the paper conveying and separation process. Currently used paper loosening blower mechanisms are simple unidirectional direct blowing; the blowing coverage area is small, requiring multiple identical paper loosening blower mechanisms to meet the demand, and increasing the difficulty and cost of laying the blowing air pipes. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a paper-loosening and splitting blower mechanism, which adopts the following technical solution:

[0004] The paper-blowing blower mechanism includes a Y-shaped nozzle, which is assembled from an upper shell and a lower shell. Both the upper and lower shells have grooves on one side and can be symmetrical. One side is shell-shaped on the outside and hollow inside, while the other side is forked to form two air outlets. Each air outlet has a gap to form an air vent. When the upper and lower shells are assembled, they can be completely spliced ​​together on one side of the groove to form an air inlet channel, and the gaps between the upper and lower shells at the air outlets can be completely spliced ​​together to form two air outlets.

[0005] Furthermore, a recessed portion is formed in the middle of the air outlet of the upper housing, and a protruding portion is formed in the middle of the air outlet of the lower housing. The recessed portion of the air outlet of the upper housing and the protruding portion of the air outlet of the lower housing cooperate to form a complete air outlet. Alternatively, an opposite splicing structure can be adopted, that is, a protruding portion is formed in the middle of the air outlet of the upper housing, and a recessed portion is formed in the middle of the air outlet of the lower housing. The protruding portion of the air outlet of the upper housing and the recessed portion of the air outlet of the lower housing cooperate to form a complete air outlet. This concave-convex splicing structure can ensure the integrity of the splicing and is simple and reliable to assemble. After the two are spliced, the upper housing and the lower housing can be connected together by bolts or by other methods, such as screws or welding, to ensure that the upper housing and the lower housing are completely assembled together, forming a reliable air intake channel and air outlet.

[0006] Furthermore, the air intake channel is connected to one side of the air blowing pipe, the other side of the air blowing pipe is connected to the base, the top of the base is connected to one end of the movable tube, the other end of the movable tube can move up and down in the sleeve, the movable tube is provided with a limiting pin, one end of the sleeve is connected to the clamp, the clamp is clamped on the frame, the sleeve is provided with a gap for the limiting pin of the movable tube to move up and down, the outer side of the sleeve is threaded, an adjusting nut is installed on the sleeve, the adjusting nut is located below the limiting pin, a spring is sleeved on the movable tube, one end of the spring abuts against the top of the base, and the other end abuts against the bottom of the sleeve.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] The bifurcated structure of the upper and lower shells allows one air inlet pipe to connect to multiple air outlets, reducing the need for additional air pipes and increasing the airflow coverage. Meanwhile, the assembly structure of the upper and lower shells is simple and reliable, easy to disassemble and assemble, and cost-effective. The use of springs, adjusting nuts, and limit pins ensures a wide height adjustment range, broad airflow coverage, and excellent paper conveying and separation performance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-3 As shown, a paper-blowing blower mechanism mainly consists of a Y-shaped nozzle. The Y-shaped nozzle is assembled from an upper shell 7 and a lower shell 6. One side of both the upper shell 7 and the lower shell 6 is an open groove-type shell structure. The other side of both the upper shell 7 and the lower shell 6 is bifurcated to form two air outlets. Each air outlet has a gap to form an air outlet hole. The bottom surface of the upper shell 7 is open, and the top surface of the lower shell 6 is open. The upper shell 7 and the lower shell 6 are symmetrically assembled. They can be completely spliced ​​together on one side of the groove to form an air inlet channel 16. The air inlet channel 16 can be connected to the air blowing pipe 4. The gaps on the bifurcated air outlets of the upper shell 7 and the lower shell 6 are completely spliced ​​together to form two air outlets 15. Air enters the air inlet channel 16 through the air blowing pipe 4 and is blown out from the air outlets 15.

[0017] The lower bottom surface of the bifurcated air outlet of the upper housing 7 is recessed on both sides of the gap, and the upper top surface of the bifurcated air outlet of the lower housing 6 protrudes on both sides of the gap. The recessed part of the bifurcated air outlet of the upper housing 7 and the corresponding protruding part of the bifurcated air outlet of the lower housing 6 cooperate to form a complete air outlet. The upper housing 7 and the lower housing 6 can be locked together with nuts 11 and bolts 12 to ensure that the upper housing 7 and the lower housing 6 are completely assembled together to form a reliable air intake channel 16 and air outlet 15.

[0018] The air intake channel 16 is connected to one side of the air blowing pipe 4, and the other side of the air blowing pipe 4 is fixedly connected through the through hole of the base 14. The upper part of the base 14 is connected to one end of the movable pipe 5, and the other end of the movable pipe 5 can move up and down in the sleeve 2. A limit pin 9 is provided on the movable pipe 5. One end of the sleeve 2 is connected to the clamp 3. The clamp 3 can be clamped and fixed on the frame by fastening bolts 12 and locking screws 13. A gap is provided on the sleeve 2 for the limit pin 9 of the movable pipe 5 to move up and down. The outer side of the sleeve 2 is threaded. An adjusting nut 1 is installed on the sleeve 2. The adjusting nut 1 is located below the limit pin 9. A spring 8 is sleeved on the movable pipe 5. One end of the spring 8 abuts above the base 14, and the other end abuts below the sleeve 2. Rotating the adjusting nut 1 can drive the limiting pin 9 and the movable tube 5 to move up and down in the sleeve 2. The compressed spring 8, under the action of elastic force, pushes the movable tube 5 to move in the direction of spring force release, thereby driving the limiting pin 9 to fit tightly against the adjusting nut 1, thus realizing the height adjustment of the air outlet 15 relative to the clamp 3, meeting the height requirements of different working conditions. When an accident or extreme working condition occurs, the material pushes the bottom surface of the base 14 of the entire mechanism upward, thereby pushing the movable tube 5 to move upward in the sleeve 2 and compressing the spring 8. At this time, the limiting pin 9 disengages from the adjusting nut 1, thus protecting the mechanism from damage by the material. When the accident or extreme working condition is resolved, the compressed spring 8 resets, thereby driving the movable tube 5 and the limiting pin 9 back to their original working positions.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
