Description

Technical Field

[0001] The invention belongs to the technical field of thermos cup processing equipment, and in particular relates to a thermos cup necking machine. Background Art

[0002] In the field of workpiece processing, such as the processing of thermos cups and thermos pots, shrinking the blanks of thermos cups and thermos pots is a very common process. Shrinking refers to putting the pre-formed cylindrical or tubular blanks on a rotating cup pressing mold, and then using the blank positioning component to press the blank onto the cup pressing mold so that the blank rotates with the mold, and finally using a rotatable shrinking roller or shaping disk to press against the outside of the blank to shrink the corresponding position of the blank.

[0003] The existing thermos cup shrinking machines basically have a motor driving a single feed tray, and the single feed tray drives a single blank to shrink. This structure is inefficient. There are also single shrinking machines equipped with two motors and two feed trays in parallel to shrink two blanks at the same time. This structure cannot use robots for effective high-speed production. For example, Chinese patent publication number CN110918801A discloses an efficient and compact thermos cup shrinking machine, which adopts double-station shrinking. However, the two shrinking rollers are located on one side of the feed turntable. When robots are needed to pick up and place cups to realize automated assembly line production, the two robots can only be placed on the other side of the frame. It is easy for robots to interfere with each other during operation. In order to avoid interference, the robot needs to change its movement and rhythm to avoid it during operation, which will have a greater impact on the robot's work efficiency, so it is impossible to use robots for efficient automated production. In addition, in order not to affect the removal of the blank from the cup pressing mold and the placement of the blank on the cup pressing mold, the blank positioning component used for pressing needs to move up and down a long distance. The current thermos cup shrinking machine uses top vertical long-stroke upper and lower cylinders for pressing. The stroke of the upper and lower cylinders is as long as 500mm. It takes a long time for the cylinders to extend and retract once, resulting in long waiting time and low efficiency. In addition, the cylinder is installed at a high place, which occupies a large space, and the structure is unstable, which affects the pressing effect. Summary of the invention

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] Combination Figures 1 to 3 As shown, an insulation cup necking machine provided by an embodiment of the present invention comprises a frame 1, the frame 1 is in the shape of a platform as a whole, two rotating tables 2 are arranged on the frame 1 at intervals, and a rotating table driving component 3 for driving the rotating table 2 to rotate is arranged below the frame 1, and the rotating table driving component 3 is a motor. A cup pressing mold 4 is fixedly arranged on the rotating table 2, and the cup pressing mold 4 can be foldably fixed on the rotating table 2 by fasteners, so that it is convenient to replace the cup pressing mold 4 to perform necking operations on insulation cup blanks of different height sizes. The frame 1 is provided with a pressing mechanism 5 between the two rotating tables 2, and the pressing mechanism 5 comprises a pressing base 51 arranged on the frame 1, two pressing heads 52 which can be vertically lifted and rotatably arranged on the pressing base 51, and a pressing head lifting driving component 53 which drives the pressing heads 52 to lift and lower so that the two pressing heads 52 are respectively close to or away from the upper ends of the two pressing cup molds 4, and the pressing head lifting driving component 53 is preferably a cylinder. The frame 1 is symmetrically provided with at least one shaping mechanism 6 on the outside of the two rotating tables 2. In this embodiment, one shaping mechanism 6 is symmetrically provided on the outside of the two rotating tables 2. Alternatively, two or more shaping mechanisms 6 may be symmetrically provided on the outside of the two rotating tables 2 according to the need of shrinking the blank at multiple positions (such as shrinking the mouth, middle or bottom at the same time). The shaping mechanism 6 includes a shaping base 61 provided on the frame 1, a shaping disk 62 which can be laterally moved on the shaping base 61 in the inner and outer directions, and a lateral movement driving component 63 which drives the shaping disk 62 to move laterally so that the shaping disk 62 approaches or moves away from the side of the corresponding cup pressing mold 4. The lateral movement driving component 63 is preferably a screw nut mechanism driven by a motor, and the lateral movement direction of the shaping disk 62 is substantially parallel to the line between the two rotating tables 2. The rotation axes of the rotating table 2, the lower pressure head 52 and the shaping disk 62 are all parallel to the vertical direction.

[0023] When the vacuum flask necking machine provided by the embodiment of the present invention is used, Figure 2As shown, the two robots are respectively placed on the upper and lower sides of the frame, and the space between the two shaping mechanisms forms a blank taking and placing channel. The lower pressure head lifting and lowering driving component 53 drives the lower pressure head 52 to rise, and the lower pressure head 52 is away from the upper end of the cup pressing mold 4. The transverse driving component 63 drives the shaping disk 62 to move laterally away from the corresponding side of the cup pressing mold 4. The robot puts the cylindrical or pipe blank to be shrunken on the cup pressing mold 4, and the lower pressure head lifting and lowering driving component 53 drives the lower pressure head 52 to descend, so that the lower pressure head 52 is stuck in the upper end of the blank. The rotating table driving component 3 drives the rotating table 2 to rotate, and the blank can rotate with the cup pressing mold 4. The transverse driving component 63 drives the shaping disk 62 to move laterally against the mouth, middle or bottom outer side of the blank on the cup pressing mold 4 to shrink the corresponding position of the blank. After the necking is completed, the lateral drive component 63 drives the shaping disk 62 to move horizontally away from the upper side of the corresponding cup pressing mold 4, and the lower pressure head lifting drive component 53 drives the lower pressure head 52 to rise away from the upper end of the cup pressing mold 4, and the robot takes the necked blank out of the cup pressing mold 4. The thermos cup necking machine provided by the embodiment of the present invention adopts a double station, which can perform necking processing on two thermos cup blanks at the same time, with high processing efficiency. The lower pressure mechanism is arranged between the two rotating tables, and the two shaping mechanisms are symmetrically arranged on the outside of the two rotating tables, and the shaping mechanisms can move horizontally left and right. The left and right symmetrical arrangement reserves enough space for the two middle rotating tables as blank picking and placing channels, so that the robot can be directly placed on both sides of the frame, and there is no interference between robots and robots, or robots and equipment during operation, which is conducive to the use of robots to achieve efficient automated assembly line production, and transform the thermos cup processing industry from the existing manual intensive to processing automation.

[0024] As a further preferred embodiment, the shaping mechanism 6 further includes a guide rail mounting plate 64 disposed on the shaping base 61, a guide rail 65 disposed on the guide rail mounting plate 64, a slider 66 slidably matched with the guide rail 65, and a shaping disk mounting frame 67 disposed on the slider 66. The guide rail 65 is two rails arranged in an upper and lower manner, and the extending direction of the guide rail 65 is parallel to the lateral movement direction of the shaping disk 62. The lateral movement driving component 63 is disposed between the slider 66 and the guide rail mounting plate 64 to drive the slider 66 to slide on the guide rail 65. The shaping disk 62 is rotatably mounted on the shaping disk mounting frame 67, and the rotation axis of the shaping disk 62 is parallel to the vertical direction. In this way, a smooth lateral movement of the shaping disk 62 can be achieved.

[0025] As a further preferred embodiment, the guide rail mounting plate 64 can be vertically lifted and lowered on the shaping base 61, and a shaping disk lifting driving component 68 for driving the guide rail mounting plate 64 to lift and lower is provided between the shaping base 61 and the guide rail mounting plate 64. The shaping disk lifting driving component 68 is preferably a screw lifter, which is specifically a screw nut mechanism driven by a motor, and the shaping disk lifting driving component 68 can drive the guide rail mounting plate 64, the slider 66, and the shaping disk 62 to lift and lower as a whole, so as to adapt to the shrinking operation of the thermos cup blanks of different heights.

[0026] As a further preferred embodiment, a lifting guide sleeve 69 is provided on the guide rail mounting plate 64, and a lifting guide rod 60 cooperating with the lifting guide sleeve 69 is provided on the shaping base 61. There are two lifting guide sleeves 69 and two lifting guide rods 60 to guide the lifting action of the guide rail mounting plate 64 to ensure the smoothness of the lifting action. In order to further increase the smoothness of the lifting action, a linear bearing can also be provided between the lifting guide sleeve 69 and the lifting guide rod 60.

[0027] As a further preferred embodiment, Figure 3As shown, the pressing mechanism 5 also includes a pressing mounting seat 54, a pressing shaft 55, a pressing arm 56 and a pressing shaft rotation driving component 57. The pressing mounting seat 54 can be vertically lifted and lowered on the pressing base 51. The pressing head lifting driving component 53 is arranged between the pressing base 51 and the pressing mounting seat 54 to drive the pressing mounting seat 54 to rise and fall. The pressing shaft 55 is rotatably arranged on the pressing mounting seat 54. The rotation axis of the pressing shaft 55 is parallel to the vertical direction. The upper end of the pressing shaft 55 is fixedly connected to the middle part of the pressing arm 56. The two pressing heads 52 are respectively rotatably arranged below the two ends of the pressing arm 56. The pressing shaft rotation driving component 57 is arranged between the pressing mounting seat 54 and the pressing shaft 55 to drive the pressing shaft 55 to rotate. When the pressing mechanism is pressing the blank, the insulation cup blank to be shrunken is placed on the cup pressing mold 4, and the pressing shaft rotation driving component 57 is controlled to drive the pressing shaft 55 to rotate, and the pressing shaft 55 drives the pressing arm 56 to rotate, so that the pressing head 52 under the end of the pressing arm 16 is facing the mouth of the insulation cup blank to be shrunken, and then the pressing head lifting driving component 53 is controlled to drive the pressing mounting seat 54 to descend, so that the pressing head 52 is stuck in the mouth of the insulation cup blank, so that the insulation cup blank is fixed on the cup pressing mold and rotates with the cup pressing mold, which is convenient for the shrinking operation of the insulation cup blank. When the shrinking operation is completed, the pressing head lifting driving component 53 is controlled to drive the pressing mounting seat 54 to rise, so that the pressing head 52 is moved out of the mouth of the thermos cup blank, and then the pressing shaft rotation driving component 57 is controlled to drive the pressing shaft 55 to rotate, and the pressing shaft 55 drives the pressing arm 56 to rotate, and the pressing head 52 below the end of the pressing arm 56 is moved away from the mouth of the thermos cup blank, so that the robot can take the shrinking thermos cup blank out of the pressing cup mold. In this way, the stroke of the lifting driving component can be small, and the action time can be greatly shortened, thereby shortening the pressing time and improving the efficiency of shrinking the thermos cup. In addition, the pressing mechanism 5 can be installed at a lower position, occupying less space, and the structural stress is better, which ensures the pressing effect.

[0028] As a further preferred embodiment, a guide sleeve 58 is provided on the pressing base 51, and a guide rod 59 cooperating with the guide sleeve 58 is provided on the pressing mounting seat 54. There are two guide sleeves 58 and two guide rods 59 to guide the lifting action of the pressing mounting seat 54 to ensure the stability of the lifting action. In order to further increase the stability of the lifting action, a linear bearing can be further provided between the guide sleeve 58 and the guide rod 59.

[0029] As a further preferred embodiment, the pressing base 51 can be vertically lifted and lowered on the frame 1, and an elevator 7 for driving the pressing base 51 to be lifted and lowered is provided between the frame 1 and the pressing base 51. The elevator 7 is preferably a screw elevator, which is specifically a screw nut mechanism driven by a motor, and the pressing mechanism 5 can be driven to be lifted and lowered as a whole by the elevator 7 to adapt to the shrinking operation of the thermos cup blanks of different heights.

[0030] As a further preferred embodiment, the lower pressure head lifting drive component 53 is preferably a cylinder, which can be a short-stroke cylinder, such as a 50mm stroke. The short-stroke cylinder has a fast action, which is conducive to shortening the time of pressing the blank. The lower pressure head lifting drive component 53 can also be an electric push rod, and the lower pressure shaft rotation drive component 57 is a worm gear mechanism driven by a rotating cylinder or a motor.

[0031] As a further preferred embodiment, the pressing shaft rotation driving component 57 drives the pressing shaft 55 to rotate back and forth, and the rotation angle is 90 degrees. In this way, in the non-pressing state, the pressing arm 56 and the pressing head 52 can avoid the robot to the greatest extent. In addition, the rotation action time is also relatively short, which is conducive to shortening the time of pressing the blank and improving the efficiency of shrinking the mouth of the thermos cup.

[0032] Many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein, and therefore, they should not be construed as limiting the scope of protection of the present invention.

[0033] In summary, although the present invention lists the above-mentioned preferred embodiments, it should be noted that although technicians in this field can make various changes and modifications, unless such changes and modifications deviate from the scope of the present invention, they should be included in the protection scope of the present invention.
