The cover blocking wheels are arranged on the two sides of the cover collecting channel, and the distance between the cover blocking wheels is matched with the diameter of the tank cover; the elastic layer is arranged on the outer wall of the cover blocking wheel; the power element is arranged on one side of the cap collecting cylinder and used for driving the cap blocking wheel to rotate; the first mounting hole is formed below the cover blocking wheel and used for mounting a sensor; and the second mounting hole is formed below the first mounting hole and is used for mounting a sensor. After the cover conveying device conveys covers into the cover collecting channel, the area above the center of the cover stopping wheel is a cover storage area, the covers make contact with the elastic layer, when the sensor on the second mounting hole does not detect the covers, the power element controls the cover stopping wheel to rotate for cover falling, and when the height of the falling covers reaches the position of the first mounting hole, the cover stopping wheel stops rotating. A sensor installed in the first installation hole controls a power element to stop, and intermittent cover falling is achieved through repeated circulation.

Description

Technical Field

[0001] The utility model relates to the technical field of capping equipment, in particular to an intermittent capping device. Background Art

[0002] In high-speed sealing operations, the cap feeding device is an indispensable part of the can seamer. Currently, the high-speed cap separation and feeding of the cap feeding device adopt a rotating method. For example, the Chinese patent authorization announcement number CN208979637U discloses a synchronous cap feeding mechanism. The mechanism includes a cap collecting device arranged above the synchronous belt, and a cap feeding device is arranged below the cap collecting device. The cap feeding device includes a blanking disk, and the rotation of the blanking disk drives the caps to rotate to separate and convey the caps at the bottom of the cap collecting device. When the caps are separated and conveyed, relative rotation will occur with the adjacent caps above. Since a certain amount of caps are stored in the cap collecting device, it will cause a large pressure on the caps at the bottom of the cap collecting device, and under a certain pressure, it is possible to cause the phenomenon that the coating on the cap surface is scratched by the burrs of the cap mouth, resulting in unqualified product quality after sealing. Content of the Utility Model

[0003] To overcome the deficiencies of the background art, the utility model provides an intermittent capping device, which solves the problem that the surface of the cap is scratched when the current cap feeding device feeds the cap.

[0004] The technical solution adopted by the utility model is as follows:

[0005] The intermittent capping device includes a cap collecting cylinder, and the cap collecting cylinder is provided with a cap collecting channel, and further includes:

[0006] Blocking wheels are arranged on both sides of the cap collecting channel, and the distance between the blocking wheels matches the diameter of the can cap;

[0007] An elastic layer is arranged on the outer wall of the blocking wheel;

[0008] A power element is arranged on one side of the cap collecting cylinder and is used to drive the blocking wheel to rotate;

[0009] A first mounting hole is arranged below the blocking wheel and is used to mount a sensor;

[0010] A second mounting hole is arranged below the first mounting hole and is used to mount a sensor.

[0011] The distance between the blocking wheels is adjustable.

[0012] U-shaped grooves are arranged on both sides of the cap collecting cylinder, mounting blocks for cooperating with the blocking wheels are arranged in the U-shaped grooves, the length of the U-shaped grooves is greater than the length of the mounting blocks, and locking pieces for cooperating with the mounting blocks are arranged on the cap collecting cylinder.

[0013] One side of the mounting block is provided with a threaded rod which passes through the bottom of the U-shaped groove, and an adjusting nut is arranged on the threaded rod.

[0014] The cover blocking wheel is an I-shaped wheel, and the elastic layer is arranged on the circumferential outer walls of the upper and lower discs of the I-shaped wheel.

[0015] The elastic layer is a rubber layer.

[0016] It further includes a mounting plate arranged on the cover collecting cylinder. The first mounting hole is arranged on the mounting plate, and the mounting plate is provided with a waist-shaped hole for cooperating with the cover collecting cylinder.

[0017] Flanges are arranged at the upper and lower ends of the cover collecting cylinder.

[0018] The beneficial effects of the utility model are as follows:

[0019] The power element is a reduction motor. After the cover feeding device feeds the cover into the cover collecting channel, the area above the center of the cover blocking wheel is the cover storage area, and the cover contacts the elastic layer. When the sensor on the second mounting hole does not detect the cover, the reduction motor controls the cover blocking wheel to rotate for cover dropping. When the height of the dropped cover reaches the position of the first mounting hole, the sensor arranged on the first mounting hole controls the reduction motor to stop, and the intermittent cover dropping is realized by repeating the cycle; this device can effectively reduce the pressure on the cover at the bottom of the cover collecting channel during cover feeding, thereby ensuring that the surface of the cover will not be scratched.
