[0018] This utility model provides, for example Figures 1 to 3The diagram shows a stretching and spinning structure for a metered inhalation aerosol can, which includes a longitudinal mounting base 1, a transverse mounting base 13, and a platform 17 fixed to a spinning device.

[0019] A first limiting groove is formed on the vertical mounting base 1, and a first sliding block 2 is slidably mounted in the first limiting groove. A horizontal support plate is welded and fixed on the first sliding block 2. A drive shaft 3 is vertically placed on the support plate, and the drive shaft 3 passes through the support plate and is rotatably connected to the support plate.

[0020] A first drive mechanism is mounted on the support plate, and the first drive mechanism is connected to the drive shaft 3. The first drive mechanism includes a first motor 4, which is fixed to the support plate. A first pulley 6 is fixedly sleeved on both the output shaft of the first motor 4 and the drive shaft 3, and the two first pulleys 6 are driven by a drive belt 5.

[0021] The bottom end of the drive shaft 3 is coaxially fixedly connected to the fixing sleeve 20, and a mandrel 19 is coaxially inserted into the fixing sleeve 20. The mandrel 19 is fixedly connected to the fixing sleeve 20.

[0022] A tripod 16 is fixed on the platform 17, and a cylinder 15 is fixedly installed on the tripod 16. The output shaft of the cylinder 15 is vertically upward and fixedly connected to a support base. A tray 18 for placing aerosol cans is rotatably installed on the top of the support base.

[0023] The support platform 18 is located below the spindle 19, which is inserted into the aerosol can and engages with it in a transmission mechanism.

[0024] A second limiting groove is formed on the horizontal mounting base 13 along the horizontal direction. A second sliding block 12 is slidably mounted in the second limiting groove. A support frame 11 is welded to the top of the second sliding block 12. A pressure roller shaft 14 is vertically placed on the support frame 11 and is rotatably connected to the support frame 11.

[0025] A second drive mechanism is mounted on the support frame 11, and the second drive mechanism is connected to the pressure roller shaft 14. The second drive mechanism includes a second motor 8, which is fixed on the support frame 11. A second pulley 10 is fixedly sleeved on both the output shaft of the second motor 8 and the pressure roller shaft 14, and the two second pulleys 10 are driven by a belt 9.

[0026] A pressure roller 7 is fixedly sleeved on the pressure roller shaft 14, and the pressure roller 7 rolls and abuts against the neck of the aerosol can.

[0027] Working principle: The aluminum material used to manufacture the aerosol cans undergoes seven processes in sequence on the stretching machine: cup punching, stretching, edge pressing, edge trimming, shoulder reduction, mouth reduction, and bottom arching. The semi-finished quantitative inhalation aerosol cans then pass through a transition section and arrive at the designated station of the spinning machine. The spinning machine can be multiple machines, and the transition section includes multiple conveying and diversion channels.

[0028] The shapes of the aerosol cans for the seven processes of the stretching machine are as follows. Figure 2 In this context, 'a' represents the aluminum sheet used in the production of aerosol cans, after... Figure 2 After the b-shaped cup is initially formed into a can shape, it undergoes gradual stamping. Figure 2 c, d, and e in the figure achieve the stretching of the can body, and the outer diameter and wall thickness of the aerosol can decrease in sequence. Figure 2 In the figure, f represents the pressure edge, and the can opening forms a smooth, outward-expanding profile. Figure 2 In this context, 'g' represents the cutting edge. The tool trims along the outward-expanding contour edge, leaving only a small section of the contour. Figure 2 The 'h' in the figure represents the shoulder, where the upper part of the aluminum can shrinks inward after molding, forming a shoulder with a smaller diameter. Figure 2 In the figure, 'i' represents the narrowing, where a small section of the can opening narrows inwards. Figure 2 In the diagram, 'j' represents the arched bottom. After the bottom of the aerosol can is pressurized, it arches upwards to form a specific shape. At this point, except for the spinning process, the aerosol can has basically completed its body forming.

[0029] After that, as Figure 3 Initially, the output shaft of cylinder 15 is in a retracted state, the support platform 18 is in a low position, and the first slide 2 and the second slide 12 are in the upper limit position and the right limit position, respectively. When the semi-finished aerosol can reaches the support platform 18, the output shaft of cylinder 15 extends upward and drives the support platform 18 to lift the aerosol can through the support seat until the neck of the aerosol can to be processed is at the same height as the pressure roller 7.

[0030] Then, the first slide block 2 slides downwards until the spindle 19 is inserted into the aerosol can. This process can be driven by a hydraulic cylinder to slide the first slide block 2, which is prior art and will not be described in detail here.

[0031] Subsequently, the second slide block 12 slides horizontally to the left, causing the support frame 11 to slide horizontally to the left. The support frame 11 then drives the pressure roller 7 to gradually approach and press against the neck of the aerosol can. This process can also be achieved by driving the second slide block 12 to slide using an existing hydraulic cylinder.

[0032] The mandrel 19 is fitted against the inner right wall of the aerosol can. Then, the first motor 4 and the second motor 8 start, and the mandrel 19 and the pressure roller 7 maintain the same rotation speed to prevent relative slippage between the aerosol can and the pressure roller during the spinning process. After spinning is completed, the support table 18, the first slide 2, and the second slide 12 all return to their initial positions, and the aerosol can is transported off the support table 18, allowing the next semi-finished aerosol can to enter the processing position. Optionally, in actual production, the contour shape of the pressure roller 7 can be designed according to the required spinning shape; the sliding distance of the second slide 12 can be adjusted according to the required spinning depth; and the stroke of the cylinder 15 can be adjusted according to the required spinning position to adjust the height of the pressure roller relative to the aerosol can.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
