Description

Technical Field

[0001] The utility model relates to the technical field of automation, and more specifically, to a limiting device for a dental floss box. Background Art

[0002] A dental floss rod, also known as a dental floss pick, is a product used in daily oral care in conjunction with a toothbrush. Before dental floss rods, people used dental floss to achieve the same effect. Compared with dental floss, dental floss rods have the advantages of being more convenient, efficient, safe, and hygienic. In the sales of dental floss rod products, several dental floss rods are placed in a box or a bag and sold in whole boxes or whole bags. In the prior art, after multiple dental floss rods are simultaneously molded in an injection molding machine, a manipulator grabs them onto a carrying rack, and then workers place them into a box according to the specified quantity to complete the box loading operation. However, during the manual box loading process, it is inevitable to contaminate the dental floss rods, which cannot guarantee product hygiene. Moreover, the operation time is long and the efficiency is low, seriously affecting the production efficiency of enterprises. At the same time, the labor cost is also relatively high.

Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention, where the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0019] Refer to Figures 1-4 As shown, a limiting device for a dental floss box includes a limit base 1, a limiting member 2 disposed on the limit base 1 and capable of abutting against one side of the dental floss box, and a clamping member 3 disposed on the limit base 1 and capable of cooperating with the limiting member 2 to clamp the dental floss box. The limiting member 2 includes a widthwise limiting post 21 located on one side of the dental floss box in the width direction and a lengthwise limiting post 22 located on one side of the dental floss box in the length direction. The limiting posts are detachably and fixedly connected to the limit base 1, and in order to improve the limiting stability of the dental floss box, the number of limiting posts or the contact area with the dental floss box can be increased;

[0020] The clamping member 3 includes a widthwise clamping block 31 located on one side of the dental floss box in the width direction and a lengthwise clamping block 32 located on one side of the dental floss box in the length direction. The widthwise clamping block 31 is slidably connected to the limit base 1, and the sliding direction of the widthwise clamping block 31 on the limit base 1 is the width direction of the dental floss box. The lengthwise clamping block 32 is slidably connected to the limit base 1, and the sliding direction of the lengthwise clamping block 32 on the limit base 1 is the length direction of the dental floss box. Clamping elastic members 33 are disposed between the widthwise clamping block 31 and the lengthwise clamping block 32 and the limit base 1. The widthwise clamping block 31 can cooperate with the widthwise limiting post 21 to clamp both sides of the dental floss box in the width direction through the clamping elastic member 33, and the lengthwise clamping block 32 can cooperate with the lengthwise limiting post 22 to clamp both sides of the dental floss box in the length direction through the clamping elastic member 33.

[0021] When the dental floss box is placed on the limit base 1, one side of the dental floss box fits against the limit member 2, and the other side is clamped by the clamping member 3 to achieve positioning and clamping of the dental floss box. Therefore, this limiting device can achieve detachable clamping of the dental floss box through the cooperation of the limit and the clamping block, making it possible for the automatic feeding and installation of the dental floss box, and then realizing full automation, which is beneficial to improving production efficiency and reducing labor costs.

[0022] On the sides of the wide clamping block 31 and the long clamping block 32 away from the dental floss box, there are guiding slide rods 34 slidably connected to the limit base 1. The clamping elastic member 33 includes a clamping spring, and the clamping spring is sleeved on the guiding slide rod 34. The clamping block can achieve sliding connection on the limit base 1 through the guiding slide rod 34, and a conducting slide hole for the guiding slide rod 34 to slidably connect can be opened on the limit base 1. In order to provide the stability of the sliding of the clamping block, it is preferably that the outer diameter dimension of the guiding slide rod 34 matches the inner diameter dimension of the conducting slide hole, and the clamping spring sleeved on the guiding slide rod 34 can drive the clamping block to slide.

[0023] On the wide clamping block 31, the long clamping block 32 and the limit base 1, there are positioning grooves 11 for the ends of the clamping springs to be embedded. The positioning grooves 11 can accommodate the ends of the clamping springs, improving the positioning effect of the clamping springs, which is beneficial to further improving the stability of driving the clamping block to slide by the clamping springs.

[0024] On the sides of the wide clamping block 31 and the long clamping block 32 away from the dental floss box, there are stroke limiting rods 35 that can limit their sliding stroke on the limit base 1. A stroke nut 36 that can abut against the limit base 1 is screwed on the stroke limiting rod 35. When the clamping elastic member 33 pushes the wide clamping block 31 and the long clamping block 32 to clamp the dental floss box, there is a gap between the stroke nut 36 and the limit base 1. When the stroke nut 36 abuts against the limit base 1 after the dental floss box is removed, it can limit the reset of the clamping elastic member 33. The stroke limiting rod 35 and the stroke nut 36 can flexibly adjust the distance between the clamping block and the limit post, so that when the dental floss box has not been placed on the limit base 1, the distance between the clamping block and the limit post can be slightly smaller than the size of the dental floss box, thus facilitating the insertion of the dental floss box until the clamping limit is completed.

[0025] On the wide limit post 21, the long limit post 22, the wide clamping block 31 and the long clamping block 32, there are guiding inclined surfaces 4 for the dental floss box to slide in conveniently. The setting of the guiding inclined surfaces 4 is beneficial to guiding the dental floss box to slide into the accurate position, greatly improving the fault tolerance of the matching device.

[0026] A push-through opening 12 penetrating through the thickness direction is provided on the limit base 1, and the push-through opening 12 is located in the middle of the limit component 2 and the clamping component 3. The size of the push-through opening 12 needs to be smaller than the size of the dental floss box, so that the limit base 1 can not only hold the dental floss box, but also cooperate with the lifting cylinder 7 that pushes the dental floss box open from the limit base 1 for operation, facilitating the removal of the dental floss box from the limit base 1.

[0027] Two groups of limit components 2 and clamping components 3 are provided on a limit base 1. The limit component 2 includes a wide-direction limit post 21 located in the middle of the limit base 1 and two long-direction limit posts 22 respectively located on both sides of the wide-direction limit post 21. The two groups of clamping components 3 are respectively located on the corresponding two sides of the wide-direction limit post 21. This solution realizes the position optimization of the limit component 2 and the clamping component 3, which is beneficial to simplifying the limit device and improving the operation efficiency.

[0028] Disassembly and assembly structures capable of being detachably connected to the conveying chain 5 are provided on both sides of the limit base 1. The disassembly and assembly structure can be bolts and nuts. A plurality of limit bases 1 are provided, and each limit base 1 can be detachably connected to the conveying chain 5 through bolts and nuts, facilitating the maintenance and replacement of each component; when the motor drives the conveying chain 5 to rotate, it can drive each limit base 1 to move and convey, facilitating the feeding of dental floss; to improve the automation degree of dental floss rod filling, a box loading manipulator 6 capable of fitting the dental floss box onto a limit device can also be provided at the feeding end of the conveying chain 5, and a lifting cylinder 7 capable of removing the dental floss box from the limit device and a transfer cylinder 8 capable of cooperating with the lifting cylinder 7 to move the dental floss box away are also provided at the discharging end of the conveying chain 5.

[0029] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
