Description

Technical Field

[0001] This utility model belongs to the technical field of curved surface offset printing machine equipment, specifically referring to a flip-plate feeding device for a curved surface offset printing machine. Background Technology

[0002] To significantly improve productivity and reduce labor costs, the automation level of equipment manufacturing is becoming increasingly higher. The printing process of plastic cups and bowls on curved surface offset printing machines starts with feeding and conveying the material into the main machine's cup-separating system, where they are separated into individual pieces and placed onto the mold. The process then proceeds sequentially through a double-cup inspection station, a pre-printing corona treatment station, a printing station, a curing station, a broken cup rejection station, and a product collection station.

[0003] Existing feeding devices mostly rely on manual assistance or complex mechanical mechanisms for flipping plates for feeding. Manual feeding is inefficient and labor-intensive, making it difficult to meet the needs of large-scale production. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model proposes a flip-plate feeding device for curved offset printing machines, which effectively solves the problem that the feeding devices of curved offset printing machines mostly rely on manual assistance or complex mechanical mechanisms for flip-plate feeding. Manual feeding is inefficient and labor-intensive, making it difficult to meet the needs of large-scale production.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a flip-plate feeding device for a curved offset printing machine, including a base, a feeding groove is opened on the rear side of the base, vertical plates are vertically arranged on the left and right sides of the base, and an adjustment structure is fixedly arranged on the side of the vertical plate, and a flip conveying structure is provided at the front end of the adjustment structure.

[0006] The adjustment structure includes hydraulic rods fixedly installed on the inner sides of two sets of vertical plates. Four sets of hydraulic rods are installed on one side of each vertical plate, with the upper two sets of hydraulic rods rotatably installed and the lower two sets of hydraulic rods fixedly installed. A rotating seat is provided at the front end of each hydraulic rod for fixed connection to a support seat, and two sets of support seats are arranged in parallel.

[0007] The flipping conveyor structure includes a fixed base fixedly mounted on a support base, a motor fixedly mounted on the fixed base with its output shaft pointing vertically toward the support base, a rotating roller rotatably mounted on the support base and fixedly connected to the output shaft of the motor, and two sets of rotating rollers arranged in front and behind for the conveyor belt to wrap and rotate.

[0008] Preferably, the base is further provided with a feeding structure, the feeding structure including a support frame fixedly and vertically mounted on the base and located in the middle of the base, a fixed seat two fixedly mounted on one side of the support frame, a fixed seat two fixedly mounted on the fixed seat two and the output shaft of the fixed seat two pointing vertically to the support frame, two sets of rotating rollers two rotatably mounted at the front and rear ends of the support frame, one set of rotating rollers two being fixedly mounted to the output shaft of the motor two, and a conveyor belt two being wrapped around the rotating rollers two.

[0009] To achieve better adjustment, the upper and lower sides of the hydraulic rod are simultaneously extended and retracted to ensure that the width of the turning trough between the two sets of conveyor belts remains consistent, thus preventing material leakage.

[0010] To achieve the purpose of conveying more quickly, the second conveyor belt is located behind the center of the two sets of first conveyor belts.

[0011] Furthermore, an anti-slip coating is applied to one outer side of the conveyor belt.

[0012] To achieve the effect of flipping different products, the conveyor belt tilts at an angle of 45-90 degrees.

[0013] The beneficial effects of this utility model using the above structure are as follows: The curved offset printing machine flip-plate feeding device proposed in this solution has two sets of hydraulic rods controlling the tilt adjustment of the conveyor belts on the upper and lower support seats, so that the two sets of conveyor belts form an opening that is wider at the top and narrower at the bottom. At this time, when the plastic cups and bowls fall from the second conveyor belt to the middle of the two sets of conveyor belts, the small end of the plastic cups and bowls is at the bottom and the large opening is at the top, thereby flipping the whole thing and improving efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes a curved offset printing machine flip-plate feeding device, including a base 1, a feeding groove 2 opened on the rear side of the base 1, vertical plates 3 vertically arranged on the left and right sides of the base 1, and an adjustment structure 4 fixedly arranged on the side of the vertical plates 3, and a flip conveying structure 5 arranged at the front end of the adjustment structure 4.

[0022] The adjustment structure 4 includes hydraulic rods 7 fixedly installed on the inner side of two sets of vertical plates 3. Four sets of hydraulic rods 7 are installed on one side of the vertical plate 3, with the upper two sets of hydraulic rods 7 rotatably installed and the lower two sets of hydraulic rods 7 fixedly installed. A rotating seat is installed at the front end of the hydraulic rods 7 for fixed connection to the support seats 8, and two sets of support seats 8 are arranged in parallel.

[0023] The flipping conveyor structure 5 includes a fixed base 9 fixedly mounted on a support base 8, a motor 10 fixedly mounted on the fixed base 9 with its output shaft pointing vertically toward the support base 8, a rotating roller 11 rotatably mounted on the support base 8 and fixedly connected to the output shaft of the motor 10, two sets of rotating rollers 11 are arranged in front and behind for wrapping and rotating the conveyor belt 13, the outer side of the conveyor belt 13 is coated with an anti-slip coating, and the flipping tilt angle of the conveyor belt 13 is 45-90 degrees.

[0024] like Figure 1 , Figure 3 and Figure 4As shown, the base 1 is also provided with a feeding structure 6. The feeding structure 6 includes a support frame 14 fixedly and vertically mounted on the base 1 and located in the middle of the base 1. A fixed seat 15 is fixedly mounted on one side of the support frame 14. The fixed seat 15 is fixedly mounted on the fixed seat 15 and the output shaft of the fixed seat 15 is perpendicular to the support frame 14. Two sets of rotating rollers 17 are rotatably mounted on the front and rear ends of the support frame 14. One set of rotating rollers 17 is fixedly mounted to the output shaft of the motor 16. A conveyor belt 18 is wrapped around the rotating roller 17. The conveyor belt 18 is located behind the center of the two sets of conveyor belts 13.

[0025] like Figure 2 and Figure 4 As shown, the upper and lower sides of the hydraulic rod 7 are synchronously extended and retracted to ensure that the width of the turning trough between the two sets of conveyor belts 13 is consistent, thus preventing material leakage.

[0026] In practical use, the width of the two sets of lower hydraulic rods 7 is adjusted by controlling their extension and retraction according to the size of the plastic cups or bowls. Then, the angle of the two sets of upper hydraulic rods 7 is adjusted by controlling their extension and retraction, so that a conveyor tilting trough is formed between the two sets of conveyor belts 13. Then, the motor 10 drives the front rotating roller 11 to rotate, thereby driving the conveyor belt 13 to rotate. At this time, the conveyor belt 13 rotates cyclically between the front and rear sets of rotating rollers 11. Then, the motor 2 16 drives the front rotating roller 2 17 to rotate, thereby driving the conveyor belt 2 18 to rotate. The conveyor belt 2 18 rotates cyclically between the front and rear sets of rotating rollers 2 17. The finished plastic cups or bowls are placed on the conveyor belt 2 18. The conveyor belt 2 18 rotates and transports the plastic cups or bowls above the conveyor belt 13. When the plastic cups or bowls fall onto the conveyor belt 13, the narrow opening at the bottom of the plastic cup or bowl is at the bottom, and the wide opening at the top is at the top. Thus, the conveyor belt 13 neatly arranges the plastic cups or bowls for feeding, improving production efficiency. The above is the entire process of using the tilting feeding device of the curved offset printing machine.
