Description

Technical Field

[0001] The utility model relates to the field of plastic straw processing, and more specifically, to a limiting device for straw transmission. Background Art

[0002] After the processing of disposable plastic straws is completed, the straws need to be collected for sorting and packaging. Currently, disposable plastic straw processing equipment discharges the processed straws periodically, mainly by setting a downward-inclined plate at the discharge port. The straws fall onto the plate and slide down to the collection device under the action of gravity. However, during the sliding process of the straws, the straws may deflect, resulting in the difficulty in ensuring the uniform direction of the straws when they finally fall onto the collection device. As a result, when the straws fall onto the collection device, it takes a lot of manual effort to align the straws before packaging them, which reduces the efficiency of the later packaging of the straws. Utility Model Content

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0020] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] Figure 1-Figure 3 A limiting device for straw transmission provided in an embodiment of the utility model comprises:

[0022] A belt conveyor mechanism 1, wherein a plurality of position limiting components are evenly distributed on the conveyor belt;

[0023] The limiting assembly includes two limiting members 2, which are respectively arranged on both sides of the conveyor belt and connected to the conveyor belt through a connecting rod 3. The limiting members 2 are provided with a receiving groove 4 corresponding to the straw, and the bottom wall of the receiving groove 4 is flush with the conveyor belt.

[0024] The pressure strip 5 is arranged parallel to the conveyor belt and forms a limiting cavity between the pressure strip 5 and the conveyor belt to limit the position of the straw. The pressure strip 5 can be made of a material with a certain elasticity and density such as a rubber belt to ensure the limiting effect on the straw, prevent the straw from moving relative to the limiting member 2, and ensure that the straw moves with the conveyor belt. During the specific installation, the two ends of the pressure strip 5 can be fixed on the frame of the belt conveyor mechanism 1 by installation, which will not be repeated here, and it is also drawn in the attached figure.

[0025] In this embodiment, the belt conveyor mechanism 1 can be made of existing technology, which will not be described in detail here. The feeding end of the belt conveyor mechanism 1 is arranged below the discharge port of the disposable plastic straw processing equipment, and the discharge end of the belt conveyor mechanism 1 is located above the feeding port of the disposable plastic straw collection equipment. The upper horizontal part of the conveyor belt is not directly arranged below the discharge port of the processing equipment, but is arranged as follows: Figure 2As shown, there is a certain distance between the upper horizontal parts of the conveyor belt. When the conveyor belt drives multiple limiting components to rotate synchronously, when any limiting component rotates to below the discharge port of the disposable plastic straw processing equipment, the straws falling from below the discharge port fall horizontally into the receiving grooves 4 of the two limiting members 2 of the limiting component and move therewith. The moving trajectory of the straws is guided by the two limiting members 2 so that the straws enter between the upper horizontal part of the conveyor belt and the pressing strip 5. The pressing strip 5 limits the straws and prevents them from moving relative to the limiting members 2. When the limiting assembly moves to the upper horizontal part of the conveyor belt, the straws are placed on the conveyor belt, with their two ends respectively located in the receiving grooves 4, and the straws are limited by the two limiting members 2. The straws falling from the discharge port of the processing equipment fall onto multiple limiting components in turn and move therewith. When the straws move to above the feed port of the collection equipment, as shown in Figure 3 As shown, when the stopper 2 leaves the horizontal portion of the conveyor belt, the stopper 2 rotates, and the opening of the receiving slot 4 also rotates, so that the straws fall from the stopper 2 under the action of gravity and finally fall into the collection device. In this embodiment, the movement trajectory of the straws is guided by the stopper assembly to prevent the straws from rotating during movement, so that all the straws can enter the collection device at a uniform angle.

[0026] Preferably, as another embodiment of the present utility model, Figure 4 As shown, the bottom wall of the accommodating groove 4 is an arc shape matching the straw, and its two side walls are expanded outward, and the height of the side close to the feeding end of the belt conveyor mechanism 1 is greater than the height of the other side.

[0027] In this embodiment, if Figure 2-4 As shown, the height of one side of the receiving groove 4 close to the feeding end of the belt conveyor mechanism 1 is greater than the height of the other side, so that when the straw falls into the receiving groove 4, it can contact with the stopper 2 for a longer time and the moving track is more stable. When the straw needs to be separated from the stopper 2, it can also fall from the receiving groove 4 quickly.

[0028] Preferably, as another embodiment of the present invention, the limiting member 2 is detachably connected to the connecting rod 3 .

[0029] In this embodiment, if Figure 5 As shown, a square rod 6 is provided at the end of the connecting rod 3, a threaded hole 7 is provided at the end of the square rod 6, and a limiting hole corresponding to the square rod 6 is provided on the limiting member 2. The limiting member 2 is inserted into the square rod 6 through the limiting hole to position the limiting member 2 so that relative rotation does not occur between the limiting member 2 and the square rod 6. Then, a bolt 8 is installed in the threaded hole 7, and the bolt 8 is tightened until it contacts the limiting member 2 to connect and fix the limiting member 2 to the connecting rod 3.

[0030] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the embodiments shown and described herein.
