DETAILED DESCRIPTION

[0020] See also Figure 1-5 The utility model provides the following technical solutions: an anti-rotation easy-pull cover drop cover device, comprising a lower cover sleeve 1, a cover separation wheel 2, a damping block 4, an adjustment mechanism 3, a pressing mechanism 5 and an electromagnet 6, two cover separation wheels 2 are symmetrically installed at the bottom of the lower cover sleeve 1, an electromagnet 6 is installed at the bottom of the lower cover sleeve 1, an adjustment mechanism 3 is installed on the top surface of the lower cover sleeve 1, a plurality of damping blocks 4 are installed on the adjustment mechanism 3, and a pressing mechanism 5 is symmetrically installed on the top surface of the lower cover sleeve 1;

[0021] The adjustment mechanism 3 includes a gear ring 31, a motor 32, a slide rail 33, a gear 34, a support rod 35 and an arc groove 36. Several slide rails 33 are installed on the top of the lower cover sleeve 1. The damping block 4 is slidably installed on the slide rail 33 through the side wall protrusion. The support rod 35 is installed on the side wall protrusion of the damping block 4. Several protrusions are installed on the inner wall of the gear ring 31. The inner wall protrusion of the gear ring 31 is provided with an arc groove 36 matching the support rod 35. The motor 32 is installed on the side wall protrusion of the lower cover sleeve 1, and the motor 32 is installed with a gear 34 meshing with the gear ring 31.

[0022] The lower cover sleeve 1 is used to store the easy-open lid, and the cover separating wheel 2 can send the fallen easy-open lid out of the device. The cover separating wheel 2 is installed on the same side of the lower cover sleeve 1 to ensure the working effect of the cover separating wheel 2. The electromagnet 6 and the cover separating wheel 2 are located on the same side. After the easy-open lid falls, the electromagnet 6 will attract the easy-open lid to move toward the electromagnet 6. The easy-open lid contacts the cover separating wheel 2 during the movement, and is thus sent out of the device by the cover separating wheel 2. The cooperation of the cover separating wheel 2 and the electromagnet 6 makes the device suitable for easy-open lids of different sizes. In the process of the easy-open lid falling, the damping block 4 can limit the easy-open cover to prevent the easy-open cover from rotating during the downward movement. The damping block 4 can also prevent the easy-open cover from rubbing and colliding with the device during the downward movement, causing damage to the easy-open cover and the device. The adjustment mechanism 3 can adjust the position of the damping block 4 so that the device can be suitable for easy-open covers of different sizes, thereby improving the applicable scope of the device. The pressing mechanism 5 can press the easy-open covers stacked together to prevent the easy-open covers from colliding with each other during the downward movement, causing damage to the easy-open covers.

[0023] The damping block 4 can be moved on the lower cover sleeve 1 by the cooperation of the slide rail 33 and the side wall protrusion of the damping block 4. The support rod 35 is installed on the arc groove 36. When the gear ring 31 rotates, the arc groove 36 rotates together with the gear ring 31. During the rotation of the arc groove 36, the support rod 35 starts to move along the slide rail 33 under the push of the side wall of the arc groove 36. The damping block 4 starts to move under the action of the support rod 35, thereby realizing the adjustment of the position of the damping block 4. Several protrusions with arc grooves 36 are installed on the inner wall of the gear ring 31. The gear ring 31 starts During rotation, all the protrusions start to rotate, thereby achieving synchronous movement of all the damping blocks 4 and improving the efficiency of the user in adjusting the position of the damping block 4. The shape of the protrusions on the inner wall of the gear ring 31 should ensure that the rotation of the gear ring 31 will not be hindered. The motor 32 can provide power for the rotation of the gear ring 31. The power generated by the motor 32 is transmitted to the gear ring 31 through the cooperation of the gear 34 and the gear ring 31 to achieve the rotation of the gear ring 31. The number of teeth of the gear 34 is less than the number of teeth of the gear ring 31, which improves the accuracy of the adjustment mechanism 3 in adjusting the position of the damping block 4.

[0024] Specifically, the opening of the slide rail 33 faces the center of the lower cover sleeve 1 .

[0025] The positions of the centers of the circles of the damping blocks 4 and the lower cover sleeve 1 are the same, and the orientation of the slide rail 33 ensures that after the easy-open cover is stored in the device, the easy-open cover is located in the center of the device, so that the cover separating wheel 2 can send the easy-open cover out of the device.

[0026] Specifically, a protrusion that contacts the top surface of the inner wall protrusion of the gear ring 31 is provided on the top of the support rod 35 .

[0027] The top protrusion of the support rod 35 can press the inner wall protrusion of the gear ring 31 to prevent the gear ring 31 from moving longitudinally during the rotation process, thereby ensuring the stability of the gear ring 31 during the rotation process.

[0028] Specifically, the bottom surface of the damping block 4 and the bottom surface of the lower cover sleeve 1 are on the same horizontal plane.

[0029] The position of the bottom surface of the damping block 4 ensures that no matter how many easy-open covers are accommodated in the lower cover sleeve 1 , the damping block 4 can hinder the rotation of the easy-open covers, thereby ensuring the working effect of the damping block 4 .

[0030] Specifically, the pressing mechanism 5 includes a mounting frame 51, a guide rod 52, a mounting frame 53, a second motor 54, a trapezoidal block 55, a pressure block 56, a guide wheel 57, a pull wire 58 and a spring 59. The mounting frame 51 is symmetrically installed on the top surface of the lower cover sleeve 1. Two guide rods 52 are installed on the mounting frame 51. The mounting frame 53 is slidably installed on the guide rod 52 through the side wall protrusion. The trapezoidal block 55 is installed on the inner wall of the mounting frame 53 through the spring 59. Two second motors 54 are installed on the top of the mounting frame 51. A pull wire 58 is installed on the protruding shaft of the second motor 54. The pull wire 58 runs through the top surface of the mounting frame 51. One pull wire 58 is installed on the top surface of the side wall protrusion of the mounting frame 53. A guide wheel 57 is installed on the top surface of the lower cover sleeve 1. The other pull wire 58 is installed on the bottom surface of the side wall protrusion of the mounting frame 53 after bypassing the guide wheel 57 installed on the lower cover sleeve 1.

[0031] The mounting frame 53 is slidably mounted on the mounting bracket 51 through the guide rod 52. The guide rod 52 ensures the stability of the mounting frame 53 during the lifting process. By setting two guide rods 52, the mounting frame 53 is prevented from rotating during the movement, and the stability of the mounting frame 53 during the movement is further improved. The inclined surface of the trapezoidal block 55 faces upward. When the easy-open cover is placed inside the lower cover sleeve 1, the easy-open cover will push the trapezoidal block 55 into the mounting frame 53, so that the user can avoid the easy-open cover from rotating during the process of placing the easy-open cover into the lower cover sleeve 1. When the external force on the trapezoidal block 55 disappears, the trapezoidal block 55 returns to its original position under the action of the spring 59. At this time, the bottom surface of the trapezoidal block 55 contacts the top of the stacked easy-open lids, thereby achieving the pressing of the easy-open lids by the pressing mechanism 5, avoiding the easy-open lids from colliding with each other during the descent process, thereby ensuring the stability of the easy-open lids during the descent process. The installation frame 53 moves by the cooperation of the pull wire 58 and the motor 2 54, and the The guide wheel 57 can change the movement direction of the pull wire 58 connected to the bottom surface of the side wall protrusion of the installation frame 53, ensuring that the motor 2 54 can move the installation frame 53 downward through the pull wire 58. When the installation frame 53 moves upward, the motor 2 54 equipped with the pull wire 58 connected to the top surface of the side wall protrusion of the installation frame 53 reels the pull wire 58, and the other motor 2 54 releases the pull wire 58. When the installation frame 53 descends, the motor 2 54 connected to the top surface of the side wall protrusion of the installation frame 53 releases the pull wire 58, and the other motor 2 54 The two motors 54 reel in the pull wire 58, and the two motors 54 rotate in opposite directions, ensuring that the movement of the mounting frame 53 will not be hindered. During the falling process of the easy-open cover, the mounting frame 53 moves downward under the action of the motor 54 and the pull wire 58, ensuring that the easy-open cover is always in a suppressed state during the falling process, thereby ensuring the working effect of the pressing mechanism 5. The pull wire 58 has a certain elasticity, which reduces the damage to the pull wire 58 during the operation of the pressing mechanism 5 and extends the service life of the pull wire 58.

[0032] Specifically, a pressing block 56 is installed on the bottom surface of the trapezoidal block 55 , and the height of the pressing block 56 is the same as the height of the lower cover sleeve 1 . A through groove matching the pressing block 56 is provided at the bottom of the mounting frame 53 .

[0033] The pressing block 56 can press the easy-open lid. The pressing block 56 also increases the contact area between the trapezoidal block 55 and the easy-open lid, reduces the damage to the tip of the trapezoidal block 55 during the rising process of the trapezoidal block 55, and extends the service life of the trapezoidal block 55. The pressing block 56 can also prevent the trapezoidal block 55 from being inserted into the gap between the easy-open lids during the movement, causing the trapezoidal block 55 to be obstructed by the easy-open lids during the rising process. The height of the pressing block 56 ensures that the amount of easy-open lids stored inside the lower cover sleeve 1 will not affect the working effect of the pressing mechanism 5, and the shape of the through groove on the bottom surface of the mounting frame 53 ensures that the movement of the trapezoidal block 55 will not be hindered.

[0034] Specifically, the groove of the mounting frame 51 through which the pull wire 58 passes and the side wall protrusion of the mounting frame 53 are provided with guide wheels 57 that contact with the pull wire 58 .

[0035] The guide wheel 57 installed on the groove of the mounting frame 51 through which the pull wire 58 passes and the side wall protrusion of the mounting frame 53 can prevent the pull wire 58 from contacting the corner during movement, reduce the wear of the pull wire 58 during movement, and extend the service life of the pull wire 58. The guide wheel 57 can also reduce the friction force on the pull wire 58 during movement, thereby improving the smoothness of the pull wire 58 during movement.

[0036] The working principle and use process of the utility model are as follows: the easy-open cover is placed in the lower cover sleeve 1. As the easy-open cover falls, the trapezoidal block 55 is pushed into the installation frame 53 by the easy-open cover. After the easy-open cover is placed, the motor 2 54 connected to the top surface of the convex side wall of the installation frame 53 reels the pull wire 58, and the other motor 2 54 releases the pull wire 58. The installation frame 53 moves upward under the action of the pull wire 58. After the pressing block 56 moves to the top of the easy-open cover, the trapezoidal block 55 returns to its original position under the action of the spring 59, and the motor 1 32 is started. The power of the motor 1 32 is transmitted to the gear ring 31 under the cooperation of the gear 34 and the gear ring 31, and the gear ring 31 starts to rotate. As the gear ring 31 rotates, the arc groove 36 is provided. The protrusion starts to rotate, and the rotating arc groove 36 pushes the support rod 35. The damping block 4 starts to move under the action of the support rod 35. After the damping block 4 moves to a suitable position, the motor 1 32 is turned off, and the two motors 2 54 are started in reverse. The pressing block 56 presses the easy-open cover, and the cover-dividing wheel 2 and the electromagnet 6 are started. The easy-open cover of the lowest layer contacts the cover-dividing wheel 2 under the action of the electromagnet 6, and then the easy-open cover is sent out of the device by the cover-dividing wheel 2. After the easy-open cover of the lowest layer is sent out of the device, the easy-open cover moves downward. As the easy-open cover moves, the pressing block 56 moves downward under the action of the motor 2 54, so that the easy-open cover is always kept in a pressed state. After all the easy-open covers are discharged, the cover-dividing wheel 2, the motor 2 54 and the electromagnet 6 are turned off.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
