In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0037] like Figure 1 and Figure 2As shown, this embodiment provides a cap stopping device, which is arranged on one side of the cap feeding device 200. The cap feeding device 200 includes a conveyor belt, which is used to convey the caps 100 so that the caps 100 move along the extension direction of the conveyor belt, and the cap stopping device can block the caps 100 in conveyance, so that a preset number of caps 100 can be conveyed to the intermittent sterilization equipment in batches.

[0038] Specifically, the cover stopping device includes a cover stopping star wheel 1 and a stop assembly 2, wherein the cover stopping star wheel 1 includes a star wheel body 11 and a stop pin 12, the stop pin 12 is arranged on the star wheel body 11, the star wheel body 11 is provided with a plurality of slots 111 along its circumference, the cover stopping device is arranged on one side of the cover feeding device 200, some of the slots 111 of the star wheel body 11 will be located above the conveyor belt, when the cover 100 moves, one cover 100 can be located in a slot 111 correspondingly, the cover 100 located in the slot 111 moves to push the star wheel body 11 to rotate, and the stop pin 12 rotates synchronously with the star wheel body 11. The stop assembly 2 includes an abutment 22, the abutment 22 can move relative to the star wheel body 11, and when the abutment 22 moves to the first position, it will abut against the stop pin 12, thereby limiting the rotation of the star wheel body 11. The cap stopping device of this embodiment utilizes the stopped rotation of the star wheel body 11 to block the caps 100 on the conveyor belt, and the caps 100 are located in the slots 111 when passing through the star wheel body 11, and the stop assembly 2 only abuts against the stop pin 12 on the star wheel body 11, and will not cause squeezing to the caps 100.

[0039] Optionally, a counterweight hole 112 is further provided on the star wheel body 11, and the counterweight hole 112 is used to reduce the weight of the star wheel body 11 on the side where the anti-rotation pin 12 is provided, so that the star wheel body 11 maintains balance during rotation. In specific implementation, the number, position and size of the counterweight hole 112 can be adjusted according to the size of the star wheel body 11 and the weight and position of the anti-rotation pin 12.

[0040] Optionally, the stop assembly 2 further includes a stop cylinder 21, and the abutment member 22 is disposed on the output shaft of the stop cylinder 21, and the stop cylinder 21 is used to drive the abutment member 22 to move along the axial direction of the output shaft. Figure 2 As shown, in this embodiment, the axial direction of the output shaft of the stop cylinder 21 is perpendicular to the extension direction of the conveyor belt of the cover feeding device 200, the abutment 22 reciprocates along the ab direction in the figure, and the conveyor belt moves along the c direction in the figure, then the cover 100 drives the star wheel body 11 to rotate along the d direction. In order to limit the star wheel body 11 from continuing to rotate, when the driving cylinder 21 drives the abutment 22 to be in the first position, the stop pin 12 is located downstream of the abutment 22 in the moving direction of the cover 100.

[0041] Furthermore, the cover stop device further includes a detection member 4, which is disposed above the star wheel body 11, and is used to detect the number of rotations of the star wheel body 11, and the detection member 4 is connected to the stop cylinder 21 by signal. That is, when the detection member 4 detects that the star wheel body 11 has rotated a preset number of times, the detection member 4 will output a stop signal to the stop cylinder 21, so that the stop cylinder 21 drives the abutment member 22 to the first position to abut against the stop pin 12, thereby limiting the rotation of the star wheel body 11.

[0042] Optionally, the stop assembly 2 further includes a stopper 23, on which a stopper groove is arranged, the stopper groove extends along the axial direction of the output shaft, and the abutment member 22 is driven by the stopper cylinder 21 to slide in the stopper groove.

The compression gasket is sleeved on the first section and abuts against the first step surface formed by the first section and the second section. The fastening bolt is threadedly connected to the first section to press the compression gasket on the first step surface. The star wheel support 13 is vertically arranged, and when the star wheel body 11 is sleeved on the second section, the star wheel body 11 will abut against the second step surface formed by the second section and the third section under the action of gravity, and the star wheel body 11 is located between the stopper 14 and the second step surface, which can prevent the star wheel body 11 from moving in the axial direction of the star wheel support 13 when rotating. In this embodiment, the sliding sleeve 15 includes a cylinder and an outward-turned edge arranged at one end of the cylinder, the cylinder is inserted into the center hole, and the outward-turned edge is sandwiched between the star wheel body 11 and the second step surface, so as to effectively reduce the sliding friction between the star wheel body 11 and the star wheel support 13.

[0044] Optionally, the star wheel support 13 further includes a fourth section, the fourth section is connected to the third section, and the star wheel support 13 is connected to the support frame 3 of the stop cover device through the fourth section, so as to ensure the stability of the star wheel support 13 when the star wheel body 11 rotates. In other embodiments, the star wheel support 13 may also only include the first section, the second section and the third section, that is, the star wheel support 13 is connected to the support frame 3 of the stop cover device through the third section.

[0045] Optionally, when the star wheel support 13 includes the fourth section, the cover stop star wheel 1 provided in this embodiment further includes an adjusting member 16, which is sleeved on the fourth section and is located between the third section and the support frame 3. In this embodiment, the adjusting member 16 is an adjusting gasket, and the position of the star wheel body 11 in the vertical direction can be adjusted by increasing the number of adjusting gaskets, so that the star wheel body 11 can adapt to covers 100 of different sizes.

[0046] Optionally, the stopper assembly 2 is also arranged on the support frame 3. In specific implementation, the stopper cylinder 21 and the stopper 23 are arranged on the support frame 3, so that the cover stopper device can be assembled as a whole, which is convenient for transportation and installation.

[0048] Optionally, the cap feeding device 200 includes a conveyor belt, which is used to feed the caps 100. The conveyor belt provides a transmission force to the caps 100 so that the caps 100 can push the star wheel body 11 to rotate when they are located in the slot 111 of the star wheel body 11. When the star wheel body 11 is restricted from rotating by the stop assembly 2, the caps 100 will be blocked upstream of the star wheel body 11, thereby realizing intermittent cap feeding by the cap feeding device 200.
