AI Technical Summary
In existing cup bottom rolling forming devices, the radial movement of the slider is unstable and difficult to adjust, resulting in poor stability of the slider's radial movement.
An inclined hole is made on the slider, and a mating block is set on the push rod. The axial movement of the push rod is converted into the radial movement of the slider by the engagement of the inclined surface of the inclined hole and the inclined surface of the mating block. The axial position of the push rod is adjusted by adjusting the screw, so as to achieve smooth radial movement and reset of the slider.
This achieves smooth radial movement of the slider and easy adjustment, improving the slider's movement stability and adjustment accuracy.

[0026] Please refer to Figures 1 to 3 The present application provides a cup bottom rolling forming device 1, which comprises a bottom roller 100, a top rod mechanism 200 and a lifting mechanism 300. The bottom roller 100 comprises a sliding block 110, a sliding block base 120, a knurling wheel 130, a knurling die 140, a shell 150 and a belt pulley 160. The sliding block 110 and the belt pulley 160 are respectively installed at both ends of the sliding block base 120, and the belt pulley 160 drives the sliding block base 120 and the sliding block 110 to rotate together. The knurling die 140 is installed on the shell 150, and the knurling wheel 130 is installed in the inner wall of the knurling die 140 and connected to the sliding block 110. The knurling wheel 130 has a concentric position with the knurling die 140 and an eccentric position relative to the knurling die 140. When the knurling die 140 is located at the concentric position, the outer wall of the knurling wheel 130 and the inner wall of the knurling die 140 are spaced apart to form a gap, and the gap between the outer wall of the knurling wheel 130 and the inner wall of the knurling die 140 is used to place the bottom of the paper cup. The top rod mechanism 200 comprises a top rod 210, which is installed inside the sliding block base 120 and connected to the sliding block base 120 through a top rod oblique square pin 240, so that the top rod 210 can rotate synchronously with the sliding block base 120 and also can move axially relative to the sliding block base 120. The lifting mechanism 300 is connected to the top rod mechanism 200 and is used to drive the top rod 210 to move axially relative to the bottom roller 100.
[0027] With the upward movement of the ejector rod 210 along its own axial direction relative to the roller 100, the ejector rod 210 pushes the slider 110 to move radially, and the slider 110 drives the knurling wheel 130 to move from the concentric position to the eccentric position. Since the ejector rod 210 rotates synchronously with the slider base 120, the knurling wheel 130 rotates eccentrically along the inner wall of the knurling die 140, so as to form the cup bottom by rolling. With the downward movement of the ejector rod 210 along its own axial direction relative to the roller 100, the knurling wheel 130 returns to the concentric position.
[0028] Specifically, as shown in Figure 2 and Figure 3 , the cup bottom rolling forming device 1 further comprises an adjusting screw 230, the slider 110 is provided with an inclined hole 111, the inclined hole 111 has a first inclined surface 112 and a second inclined surface 113 which are arranged obliquely relative to the axial direction of the slider 110, one end of the ejector rod 210 is provided with a matching block 211 which can be inserted into the inclined hole 111, and the matching block 211 has a third inclined surface 212 for abutting against the first inclined surface 112 and a fourth inclined surface 214 for abutting against the second inclined surface 113, and the other end of the ejector rod 210 is connected to a jacking mechanism 300 through the adjusting screw 230, so that the ejector rod 210 can be adjusted up and down along its own axial direction relative to the jacking mechanism 300. The jacking mechanism 300 is used to drive the ejector rod 210 to move axially, and with the upward movement of the ejector rod 210 along its own axial direction, the third inclined surface 212 can push the slider 110 to move radially outward, and with the downward movement of the ejector rod 210 along its own axial direction, the fourth inclined surface 214 can drive the slider 110 to reset.
[0029] It can be understood that, by providing the inclined hole 111 in the slider 110 and the matching block 211 in the ejector rod 210, the first inclined surface 112 of the inclined hole 111 cooperates with the third inclined surface 212 of the matching block 211, and the second inclined surface 113 of the inclined hole 111 cooperates with the fourth inclined surface 214 of the matching block 211, the axial movement of the ejector rod 210 can be converted into the radial movement of the slider 110, and the slider 110 can be reset, so that the slider 110 can move radially more smoothly. Furthermore, by providing the adjusting screw 230, the adjusting screw 230 enables the ejector rod 210 to be adjusted up and down along its own axial direction relative to the jacking mechanism 300, so that the height of the matching block 211 relative to the jacking mechanism 300 changes accordingly. Therefore, under the condition that the jacking mechanism 300 drives the ejector rod 210 to move axially with the same stroke, the maximum height of the matching block 211 in the inclined hole 111 changes accordingly, so as to adjust the displacement of the slider 110 along the radial direction, and further to adjust the eccentric displacement of the knurling wheel 130 from the concentric position to the eccentric position.
[0030] The rolling bottom device 100 further comprises a cover plate 170, the sliding block base 120 is provided with a groove 121, the sliding block 110 comprises a first section 115 and a second section 116 connected with each other, the diameter of the first section 115 is smaller than that of the second section 116, the second section 116 is embedded in the groove 121 and fixed to the sliding block base 120 through the cover plate 170. The inclined hole 111 penetrates the sidewall of the second section 116 from the bottom of the second section 116.
[0031] Optionally, as shown in Figure 3 The shell 150 comprises an inner sleeve 152, an outer sleeve 153 and a clamp 154. The outer sleeve 153 is sleeved on the outer periphery of the inner sleeve 152, and the relative height between the outer sleeve 153 and the inner sleeve 152 can be adjusted up and down along the axial direction. The clamp 154 is used to lock and fix the outer sleeve 153 and the inner sleeve 152 after the height adjustment of the outer sleeve 153 and the inner sleeve 152 is completed.
[0032] As shown in Figure 3 The jacking mechanism 300 comprises a connecting plate 310 provided with a threaded hole 311. The top rod 210 is connected to one side of the top rod base 250, and the adjusting screw 230 is installed on the other side of the top rod base 250 and threadedly matched with the threaded hole 311.
[0033] Further, the top rod mechanism 200 further comprises a butterfly spring 260, which acts on the top rod 210 at one end and on the top rod base 250 at the other end along the axial direction of the top rod 210. It can be understood that the butterfly spring 260 plays a buffering role in the process of driving the top rod 210 to move axially by the jacking mechanism 300.
[0034] Specifically, the top rod mechanism 200 further comprises a top rod base bearing 270 and a gasket 280. The top rod base bearing 270 is sleeved on the outer periphery of the top rod 210 and installed on the top rod base 250, and the gasket 280 is installed on the top of the top rod base bearing 270. The top rod 210 is provided with an assembly groove 215, and the butterfly spring 260 is installed in the assembly groove 215 and abuts against the inner wall of the assembly groove 215 at one end and against the gasket 280 at the other end along the axial direction of the top rod 210.
[0035] The top rod mechanism 200 further comprises a circular spring 290, and the two ends of the circular spring 290 act on the shell 150 and the top rod base 250, respectively. When the jacking mechanism 300 drives the top rod 210 to move upward along the axial direction, the circular spring 290 is compressed. Then, the compressed circular spring 290 can push the top rod 210 to move upward along the axial direction, thereby facilitating the rapid resetting of the sliding block 110.
[0036] Please refer to Figure 2 and Figure 3The roller bottoming device 100 further comprises a bearing assembly 400 arranged between the slider base 120 and the housing 150. Specifically, the bearing assembly 400 comprises four pairs of bearings arranged axially along the slider base 120. In this way, when any one of the bearings is damaged, the slider base 120 can still rotate normally, thereby avoiding the slider base 120 from being damaged by impact.
[0037] Optionally, in an embodiment, two of the bearings are configured as deep groove ball bearings 410, and the other two are configured as tapered roller bearings 420, and the two tapered roller bearings 420 are arranged closer to the pulley 160 than the two deep groove ball bearings 410. It can be understood that the tapered roller bearing 420 and the deep groove ball bearing 410 are two common types of bearings, and the tapered roller bearing 420 can bear greater axial and radial loads than the deep groove ball bearing 410.
[0038] Further, as shown in Figure 2 , the slider base 120 has a first limiting surface 122, and the housing 150 has a second limiting surface 151, the first limiting surface 122 and the second limiting surface 151 are arranged opposite along the axial direction of the slider base 120 and are staggered along the radial direction of the slider base 120; wherein one deep groove ball bearing 410 and one tapered roller bearing 420 are axially stopped between the first limiting surface 122 and the second limiting surface 151. In this way, the deep groove ball bearing 410 and the tapered roller bearing 420 are axially limited.
[0039] As shown in Figure 1 and Figure 2 , the jacking mechanism 300 is provided with a camshaft 320 at an end away from the connecting plate 310, and the camshaft 320 is used to connect an external driving component.
[0040] The technical features of the above-mentioned embodiments can be combined in any manner. In order to make the description simple, not all possible combinations of the technical features in the above-mentioned embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.
[0041] The above-mentioned embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application.
