[0032] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figures 1 to 3 , an embodiment of the first aspect of the present utility model provides a chemical feeding safety baffle structure, including a substrate 1 with a through hole, a sleeve 2, an elastic component 3, and a movable feeding cylinder 4 with an opening on one side of the bottom wall.

[0034] Wherein, the sleeve 2 is arranged on the substrate 1 and communicates with the through hole, and is used to form a feeding channel, facilitating the output of the movable feeding cylinder 4 from the inside of the sleeve 2 to the outside to complete the feeding function.

[0035] A chute 21 is arranged on the inner wall of the sleeve 2, which is used to install the elastic component 3 and to limit the movement of the movable feeding cylinder 4 in the vertical direction.

[0036] Specifically, the elastic component 3 is arranged inside the chute 21 and has a sliding abutting end 31. By setting the sliding abutting end 31, it is used to support the movable feeding cylinder 4, enabling the movable feeding cylinder 4 to slowly move downwards to prevent situations such as deviation.

[0037] The movable feeding cylinder 4 is arranged inside the sleeve 2, and a positioning block 41 extending into the inside of the chute 21 is arranged on the outer wall, and the positioning block 41 abuts against the sliding abutting end 31.

[0038] It should be particularly noted that the movable feeding cylinder 4 can slide inside the chute 21 through the positioning block 41 to move relative to the sleeve 2 in the vertical direction.

[0039] Moreover, during the movement of the movable feeding cylinder 4 in the vertical direction, it can deflect relative to the sleeve 2 with the positioning block 41 as the axis, making the movable feeding cylinder 4 in an inclined state. Correspondingly, the bottom wall of the movable feeding cylinder 4 is an inclined surface. At this time, the material can flow out along the bottom wall to the opening under the action of gravity to complete the feeding.

[0040] In addition, during the process of the movable feeding cylinder 4 deflecting relative to the sleeve 2, the positioning block 41 and the sliding contact end 31 are in reciprocating vibration contact, that is, the positioning block 41 and the sliding contact end 31 can vibrate relative to each other during the deflection of the movable feeding cylinder 4, and thus a vibration acting force can be provided to the movable feeding cylinder 4, which can accelerate the discharge of materials and effectively avoid the situation of material residue. Therefore, the time spent on manual cleaning of residual materials can be saved, the feeding rate can be increased, and the accuracy of subsequent feeding can be ensured.

[0041] By providing the sleeve 2 and the movable feeding cylinder 4 that can move and deflect inside the sleeve 2 in this device, when feeding is required, only the movable feeding cylinder 4 needs to be moved to a specified height and then deflected, so that the bottom wall of the movable feeding cylinder 4 is inclined. Then, under the action of gravity, the materials can be discharged to the outside through the opening and the through hole in sequence to complete the feeding function. By providing the elastic component 3 and arranging the positioning block 41 on the outer wall of the movable feeding cylinder 4, the positioning block 41 is in contact and fit with the sliding contact end 31 of the elastic component 3, and during the process of the movable feeding cylinder 4 deflecting relative to the sleeve 2, the positioning block 41 can be in reciprocating vibration contact with the sliding contact end 31, that is, the sliding contact end 31 will apply a reciprocating vibration acting force to the movable feeding cylinder 4 to accelerate the discharge of materials. And by the vibration method, the situation of material residue is effectively avoided to ensure the accuracy of subsequent feeding, and the time required for manual cleaning of materials can be saved to achieve the purpose of improving the production rate.

[0042] In this embodiment, a specific positioning block 41 and sliding contact end 31 are proposed, so that when the movable feeding cylinder 4 deflects, the sliding contact end 31 can apply a vibration acting force to the positioning block 41, so that the movable feeding cylinder 4 can swing when deflecting, to accelerate the discharge of materials and avoid the situation of material residue.

[0043] Specifically, the positioning block 41 includes a positioning column 411 and a first protrusion 412, and the first protrusions 412 are arranged at equal intervals in a ring shape on the outer wall of the positioning column 411.

[0044] The upper surface of the sliding contact end 31 is set as an arc structure and has a plurality of second protrusions 311 that are in contact or separated from the first protrusions 412.

[0045] When the positioning block 41 deflects, the first protrusion 412 and the second protrusion 311 are switched between the extrusion and separation states. Among them, when the first protrusion 412 is separated from the second protrusion 311, under the elastic action, the second protrusion 311 is inserted into the card slot between adjacent first protrusions 412 to apply a vibration force to the positioning column 411. Since the positioning column 411 is connected to the movable feeding cylinder 4, the movable feeding cylinder 4 will also be affected by this vibration force. Therefore, it can accelerate the discharge of the material at the bottom wall of the movable feeding cylinder 4 and avoid the situation where the material remains on the bottom wall of the movable feeding cylinder 4, saving the time required for material cleaning and improving the feeding rate.

[0046] In this embodiment, to reduce the frictional resistance between the first protrusion 412 and the second protrusion 311 and avoid jamming, the first protrusion 412 and the second protrusion 311 are both set to arc-shaped structures to reduce the contact area between the two, thereby avoiding jamming.

[0047] In other embodiments, the elastic component 3 includes a compression spring 32 for providing a reset elastic force to the sliding contact end 31, so that the second protrusion 311 can be inserted into the card slots of two adjacent first protrusions 412 to achieve the function of vibrating the movable feeding cylinder 4.

[0048] Specifically, one end of the compression spring 32 is connected to the bottom wall of the chute 21, and the other end is connected to the sliding contact end 31.

[0049] In addition, to facilitate controlling the downward pressure or deflection of the movable feeding cylinder 4, a pull rod 42 extending in the vertical direction is fixedly installed on the upper surface of the movable feeding cylinder 4.

[0050] It should be noted that when the movable feeding cylinder 4 moves to the bottommost end, one end of the pull rod 42 is still exposed outside the sleeve 2, facilitating manual operation.

[0051] It should also be noted that a gap is reserved between the outer wall of the movable feeding cylinder 4 and the inner wall of the sleeve 2 for the deflection of the movable feeding cylinder 4 to prevent the situation where the movable feeding cylinder 4 can only move in the vertical direction due to the same dimensions of the outer diameter of the movable feeding cylinder 4 and the inner diameter of the sleeve 2.

[0052] In other embodiment sets, the outer wall of the sleeve 2 is rotatably connected to the inner wall of the through hole, so that the opening can be inclined in any direction towards the substrate 1 to be input into the receiving containers at different positions, meeting the feeding requirements at different positions and having stronger applicability.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
