Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to a contouring and deflashing device for a gallon barrel injection blow molding machine. Background Technology

[0002] When producing gallon buckets, molten plastic is blow-molded using an injection blow molding machine. However, after molding, flash is generated at the top and in the cavity between the handle and the top. This flash needs to be removed. Since the top of the gallon bucket is irregularly shaped, it is usually removed manually. First, the flash at the top of the gallon bucket is removed, and then the flash in the cavity between the handle and the top is removed. This method is not only inefficient, but also increases the labor intensity of workers. Utility Model Content

[0003] The purpose of this invention is to provide a contour-flash removal device for gallon barrel injection blow molding machines that can quickly remove the fringe from the top of gallon barrels.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a contouring and deflashing device in a gallon barrel injection blow molding machine, comprising: an upper and lower adjusting plate, a left and right adjusting plate, and a cutting plate. Two longitudinal elongated holes are provided on the upper and lower adjusting plates, and a first adjusting bolt is movably inserted through the longitudinal elongated holes. The first adjusting bolt is threadedly connected to the moving arm of the injection blow molding machine. Two clearance holes and several transverse elongated holes are provided on the left and right adjusting plates, and a second adjusting bolt is movably inserted through the transverse elongated holes. The left and right adjusting plates are slidably mounted on the upper and lower adjusting plates. The two first adjusting bolts on the upper and lower adjusting plates are respectively located in the two clearance holes of the left and right adjusting plates. The second adjusting bolts on the left and right adjusting plates are threadedly connected to the upper and lower adjusting plates. A fixing plate is provided at each of the left and right ends of the left and right adjusting plates. A rotating shaft is rotatably mounted between the two fixing plates and connected to a drive mechanism. The cutting plate is fixed on the rotating shaft. A contouring blade is provided on one side wall of the cutting plate. An arc-shaped plate extending towards the contouring blade is provided on the cutting plate, and a scraper is connected to the arc-shaped plate.

[0005] Furthermore, in the aforementioned gallon barrel injection blow molding machine, the contouring and deflashing device includes a drive mechanism comprising a cylinder and a gearbox. The gearbox is fixed on any fixed plate, and a rack is slidably arranged and a shafted gear is rotatably arranged in the gearbox. The shafted gear meshes with the rack. The cylinder is fixed below the gearbox, and the piston rod in the cylinder is connected to the rack in the gearbox. The shafted gear is connected to a rotating shaft through a coupling.

[0006] Furthermore, in the aforementioned gallon barrel injection blow molding machine, a contouring and deflashing device is provided on the side wall of the cutter plate away from the contouring blade, and a sensor that can cooperate with the contouring plate is provided on the fixed plate on which the gearbox is fixed.

[0007] Furthermore, in the aforementioned gallon barrel injection blow molding machine, the contouring and deflashing device has a milling plane on the rotating shaft, and the cutter plate abuts against the milling plane of the rotating shaft and is connected by a countersunk bolt threaded connection.

[0008] Furthermore, in the aforementioned gallon barrel injection blow molding machine, the contouring and deflashing device has several first jet holes on the side of the cutter plate near the contouring blade, and a first air passage connected to the first jet holes is provided in the cutter plate. The first air passage is connected to a compressed air source through an air pipe.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0020] like Figures 1 to 8As shown, the conformal trimming device in the gallon barrel injection blow molding machine of this utility model includes: an upper and lower adjusting plate 1, a left and right adjusting plate 2, and a cutting plate 3. Two longitudinal elongated holes 11 are provided on the upper and lower adjusting plate 1, and a first adjusting bolt 12 is movably inserted through the longitudinal elongated holes 11. The first adjusting bolt 12 is threadedly connected to the mounting base of the injection blow molding machine. Two clearance holes 21 and several transverse elongated holes 22 are provided on the left and right adjusting plate 2, and a second adjusting bolt 23 is movably inserted through the transverse elongated holes 22. The left and right adjusting plate 2 is slidably mounted on the upper and lower adjusting plate 1. The two first adjusting bolts 12 on the upper and lower adjusting plate 1 are respectively located in the two clearance holes 21 of the left and right adjusting plate 2. The second adjusting bolts 23 on the left and right adjusting plate 2 are connected to the upper and lower adjusting plate 3. Plate 1 is threadedly connected. A fixed plate 4 is set at each of the left and right ends of the left and right adjustment plates 2. A reinforcing angle plate 24 is set between the left and right adjustment plates 2 and the fixed plate 4 to improve the connection strength between the fixed plate 4 and the left and right adjustment plates 2. A rotating shaft 41 is rotatably set between the two fixed plates 4. The rotating shaft 41 is connected to the drive mechanism. The drive mechanism includes a cylinder 5 and a gearbox 51. The gearbox 51 is fixed on any one of the fixed plates 4. A rack 52 is slidably set in the gearbox 51 and a shafted gear 53 is rotatably set in the gearbox 51. The shafted gear 53 meshes with the rack 52. The cylinder 5 is fixed below the gearbox 51. The piston rod in the cylinder 5 is connected to the rack 52. The shafted gear 53 is connected to the rotating shaft 41 through a coupling 54. The cylinder 5 drives the piston rod, which in turn drives the rack 52 to slide up and down, thereby driving the shaft gear 53 to rotate in both directions. This, in turn, drives the rotating shaft 41 to rotate in both directions. The cutter plate 3 is fixed on the rotating shaft 41, and a milling surface is provided on the rotating shaft 41. The cutter plate 3 abuts against the milling surface of the rotating shaft 41 and is connected by a countersunk bolt threaded connection, which improves the connection strength between the cutter plate 3 and the rotating shaft 41. A contoured blade 31 is provided on one side wall of the cutter plate 3. The curve of the contoured blade 31 is the same as the top curve of the produced gallon barrel. If it is necessary to remove the burrs from gallon barrels of different sizes, this can be achieved by replacing the cutter plate 3 with a contoured blade 31 with the same curve. Several first air jet holes 32 are provided on the side of the cutter plate 3 near the contoured blade 31. The cutting plate 3 is provided with a first air passage 33 that communicates with the first jet hole 32. The first air passage 33 is connected to a compressed air source through an air pipe. A sensing plate 34 is provided on the side wall of the cutting plate 3 away from the contour blade 31. A sensor 42 that can cooperate with the sensing plate 34 is provided on the fixing plate 4 on which the gearbox 51 is fixed. An arc plate 6 extending towards the contour blade 31 is provided on the cutting plate 3. A scraper 61 is connected to the arc plate 6. Several second jet holes 62 are provided on the scraper 61. A second air passage 63 that communicates with the second jet holes 62 is provided in the scraper 61. The second air passage 63 is connected to a compressed air source through an air pipe. A slot 64 that can hold the air pipe is provided on the side wall of the arc plate 6.

[0021] In use, first fix the upper and lower adjusting plate 1 to the moving arm of the injection blow molding machine, loosen the first adjusting bolt 12 to adjust the height so that the cutter plate 3 is flush with the top of the gallon can after injection blowing, then loosen the second adjusting bolt 23 to adjust the left and right position so that the contouring blade 31 on the cutter plate 3 is in contact with the top of the gallon can. The installation direction of the contouring and deflashing device in the gallon can injection blow molding machine of this utility model is as follows: Figure 7 , Figure 8 As shown, when the blow-molded gallon bucket moves to the front of the deburring device in the gallon bucket injection blow molding machine of this utility model, the moving arm drives the deburring device in the gallon bucket injection blow molding machine of this utility model to move forward. The deburring blade 31 on the cutter plate 3 cuts off the flash on the top of the gallon bucket. Then, the cylinder 5 is started to drive the rotating shaft 41 and the cutter plate 3 to rotate. The scraper 61 on the cutter plate 3 extends into the cavity between the gallon bucket handle and the top to remove the flash in the cavity. When the cutter plate 3 rotates, the sensing plate 34 will rotate together. The sensor 42 no longer senses the sensing plate 34. After the scraper 61 completes the cutting work, the cutter plate 3 reverses. When the sensor 42 senses the sensing plate 34 again, it means that the cutter plate 3 has completed the reset and can perform the next deburring work. When removing the burr from the top of the gallon barrel, some of the burr on the cutting plate 3 will stick to the cutting blade 31. When the compressed air source is turned on, the compressed air will blow out through the air pipe, the first air passage 33 and the first jet hole 32, causing the burr stuck to the cutting plate 3 to be blown away. When the scraper 61 removes the burr, some of the burr will also stick to the scraper 61. When the compressed air source is turned on, the compressed air cavity will blow away the burr stuck to the scraper 61 through the air pipe, the second air passage 63 and the second jet hole 62.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model.
