Description

Technical Field

[0001] The present invention relates to the technical field of square can production, in particular to a quick-change process of a three-station mold. Background Art

[0002] Existing square cans are all produced using a linear production line. During normal production, one type of can requires a complete linear production line to produce it. In actual production, when the production line needs to produce another type of can, it is necessary to manually replace the corresponding molds at the original square expansion station, printing station, and flanging station, which makes mold replacement time-consuming and labor-intensive, delaying production progress. In addition, the existing linear production line needs to store and place the replaced corresponding molds, which requires additional storage space. Therefore, how to develop a production line that can adapt to both types of cans at the same time and the corresponding quick-change equipment is a technical problem that needs to be solved urgently. Summary of the Invention

DETAILED DESCRIPTION

[0019] A three-station mold quick change process, see Figure 1-Figure 3 : A pair of can type quick change modules 20 are independently set on the outside of the linear conveyor line 10. After the round can is placed at the operating station through the external clamping and positioning mechanism 30, the corresponding square expansion, printing and flanging processes are carried out in sequence according to the can shape. After that, the round can is returned to the rear station of the linear conveyor line 10 again through the external clamping and positioning mechanism 30;

[0020] The double-tank quick-change module 20 includes a base 40, on which two operating stations are arranged. A lifting mechanism 50 is provided at the bottom of each operating station. A turntable 60 is provided on the upper part of the base 40. An upper processing mold is provided at every 60° in the outer ring area of ​​the turntable 60. The upper processing molds are the first square expansion mold 61, the first printing mold 62, the first flanging mold 63, the second square expansion mold 64, the second printing mold 65, and the second flanging mold 66 in sequence. The turntable 60 rotates in steps of 60°.

[0021] In a specific implementation, all products of the same model of the upper processing mold correspond to a set of jacking mechanisms, that is, a first operating station 41 and a second operating station 42 are provided on the base 40. The first square expansion mold 61, the first printing mold 62, and the first flanging mold 63 correspond to the first operating station 41 for making the first can shape, and the second square expansion mold 64, the second hidden danger mold 65, and the second flanging mold 66 correspond to the second operating station 42 for making the second can shape.

[0022] When the two groups of can types need to be switched, the external clamping and positioning mechanism 30 transfers the round cans to the first operating station 41 or the second operating station 42 for can type switching.

[0023] During specific implementation, the first square expansion mold 61 and the second square expansion mold 64 are set corresponding to the two ends of the first diameter of the turntable 60, the first printing mold 62 and the second printing mold 65 are set corresponding to the two ends of the second diameter of the turntable 60, and the first flanging mold 63 and the second flanging mold 66 are set corresponding to the two ends of the third diameter of the turntable 60. Each group of upper processing molds is equipped with an independent driving mechanism.

[0024] In specific implementation, the first and second operating stations 41, 42 on the base 40 are arranged in a straight line. An upper convex support column 43 is provided between the first and second operating stations 41, 42. The turntable 60 is mounted at a corresponding height of the upper convex support column 43 via a bearing, and the turntable 60 rotates around the upper convex support column 43.

[0025] Specific embodiment 1, see Figure 1 It only includes a straight conveyor line 10 and an external clamping and positioning mechanism 30. A double-can quick-change module 20 is arranged next to the straight conveyor line 10. A ring gear 601 is set on the outer periphery of the turntable 60. The external motor is engaged with the ring gear 601 through a transmission gear 70. The external motor drives the outer periphery of the turntable 60 to rotate around the center of the circle through the transmission gear, driving the turntable 60 to rotate 60° twice in a clockwise direction, and then quickly reset 120° in a counterclockwise direction, so that the turntable 60 drives the corresponding square expansion mold, printing mold, and flanging mold to complete the processing of the can body and then quickly reset again.

[0026] Specific embodiment 2, see Figure 2 , a double-can quick-change mold 20 is provided with straight conveyor lines 10 for processing different types of square cans on both sides. By configuring two sets of external clamping and positioning mechanisms 30, the first operating station 41 and the second operating station 42 respectively combine the square expansion mold, the printing mold, and the flanging mold to produce two types of square cans. At this time, a synchronous belt groove 602 is provided on the outer periphery of the turntable 60, and the external motor is connected to the synchronous belt groove 602 through the synchronous belt 80 and the synchronous pulley 90. The external motor drives the synchronous pulley 90 to rotate, thereby driving the outer periphery of the turntable 60 to rotate around the center of the circle, driving the turntable 60 to rotate 60° twice in a clockwise direction, and then quickly reset 120° in a counterclockwise direction, so that the turntable 60 drives the corresponding two sets of square expansion molds, printing molds, and flanging molds to complete the processing of the can body of the two sets of straight conveyor lines 10, and quickly reset; it greatly improves production efficiency and saves a lot of land area.

[0027] Its working principle is as follows: a double-can quick-change module capable of producing two types of cans is placed next to the linear conveyor line. After the round cans are placed at the operating station through an external clamping and positioning mechanism, the corresponding square expansion, printing, and flanging processes are performed in sequence according to the can type. After that, the round cans are returned to the rear station of the linear conveyor line through the external clamping and positioning mechanism. When the two groups of can types need to be switched, the external clamping and positioning mechanism transfers the round cans to different operating stations for quick switching, which saves production line area and reduces land costs.
