Description

Technical Field

[0001] The present invention relates to the field of natural alkaline old lake salt processing, and specifically relates to a natural alkaline old lake salt filling machine with adjustable flow rate. Background Art

[0002] Filling machines are a type of packaging machine primarily used to mechanically fill materials. Based on the type of material being filled, filling machines can be categorized as liquid, paste, powder, and granule. Based on the degree of automation, filling machines can be divided into semi-automatic filling machines and fully automatic filling lines.

[0003] A search revealed a utility model patent application with authorization announcement number CN221316751U, which discloses a salt filling production line that facilitates precise control of filling volume. The production line includes multiple volumetric canning machines arranged in parallel, multiple filling conveyor belts, a finished product conveyor belt for conveying finished salt that has passed weighing and re-inspection to the next process for boxing or bagging, a conveyor belt weighing machine installed on the finished product conveyor belt for weighing and re-inspecting the finished salt after filling, a weighing QR code reader / writer, and multiple filling QR code readers / writers. Based on the QR code on the salt packaging, the utility model uses the QR code reader / writer to establish a correlation between the weight of the finished salt and the volumetric filling machine, facilitating timely adjustment of the volumetric cylinder volume to precisely control the weight range of the bagged salt.

[0004] In the existing technology, when using a filling machine to fill natural alkaline old lake salt, the natural alkaline old lake salt will always maintain a stable feeding rate for filling. However, when the filling is about to be completed, even if the feeding is stopped in time, the natural alkaline old lake salt remaining in the feeding pipe will continue to fall, which makes the amount of each filling have a certain error. At the same time, as the natural alkaline old lake salt continues to fall into the carrier, it will also cause a certain impact on the carrier, which will cause the carrier to deviate on the conveying device, affecting the filling process. Utility Model Content

[0005] The purpose of this solution is to provide a natural alkaline old lake salt filling machine with adjustable flow rate, so as to solve the problem in the existing technology that the discharge flow rate is constant, resulting in residual material in the discharge pipe causing errors in the filling volume, and at the same time solve the problem of unstable carrier during filling.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a natural alkaline old lake salt filling machine with adjustable flow rate, comprising a support frame, which is a U-shaped frame with an open horizontal arrangement, a material tank being installed on the top of the support frame, a discharge pipe being installed on the bottom of the material tank, the discharge pipe being a square tube and passing through the support frame, a fixed seat being installed on one side of the discharge pipe, a cavity being provided inside the fixed seat and the width of the cavity being consistent with the inner diameter length of the discharge pipe, the cavity being connected to the discharge pipe, a block being provided in the cavity, the outer wall of the block being gap-fitted with the inner wall of the cavity, an inclined surface being provided facing the discharge pipe on the top of the block, an electric push rod being connected to the end of the block away from the discharge pipe, the electric push rod being installed on the outer wall of the fixed seat, a conveying mechanism being provided below the discharge pipe, and a clamping mechanism being also provided below the discharge pipe.

[0007] The principle of this solution is: when in use, first place the carrier for natural alkaline old lake salt on the conveying mechanism, let the conveying mechanism convey the carrier to the bottom of the discharge pipe, then the clamping mechanism will clamp and fix the carrier, and then the electric push rod will pull the block to move into the cavity. At this time, the natural alkaline old lake salt in the material tank will fall into the carrier through the discharge pipe. As the natural alkaline old lake salt in the carrier is continuously loaded, the electric push rod can push the block out of the cavity to adjust the size of the inner cavity of the discharge pipe, thereby reducing the amount of natural alkaline old lake salt falling, until the block closes the discharge pipe, reducing the residual amount of natural alkaline old lake salt in the discharge pipe when filling is stopped, and reducing filling errors.

[0008] The technical effect of this solution is that the natural alkaline old lake salt in the discharge material is blocked by the movement of the block in the discharge pipe, thereby slowing down the falling rate of the natural alkaline old lake salt, thereby adjusting the flow rate of the natural alkaline old lake salt in the discharge path. At the same time, the blocking of the block also reduces the falling amount of the natural alkaline old lake salt, which can reduce the residual amount in the discharge pipe before filling is completed and reduce the occurrence of errors during filling.

[0009] Furthermore, a guide shaft 1 is provided parallel to the side of the electric push rod 1, one end of which is fixed to the stopper, and the other end of which slides through the fixing seat. The movement of the stopper is guided by the guide shaft 1, thereby improving the stability of the stopper during movement.

[0010] Furthermore, a telescopic hose is connected to the bottom of the discharge pipe, and a second electric push rod is provided on the side of the telescopic hose. The top of the second electric push rod is fixed to the support frame, and the bottom of the second electric push rod is mounted on a connecting seat, and the connecting seat is fixed to the bottom of the telescopic hose. By the second electric push rod extending and retracting the telescopic hose, the discharge height of the natural alkaline old lake salt can be adjusted according to the size of the natural alkaline old lake salt filling carrier, thereby preventing the natural alkaline old lake salt from splashing out during filling.

[0011] Furthermore, a sleeve is provided on the side of the telescopic hose, the top of which is fixed to the support frame, and a connecting shaft is built into the bottom of the sleeve, the bottom of which is fixed to the connecting seat. The connecting shaft slides within the sleeve to guide the upward and downward extension of the telescopic hose, thereby ensuring that the telescopic hose is aligned with the natural alkaline old lake salt filling body after extension and contraction.

[0012] Furthermore, the conveying mechanism includes two parallel beams, each with a support leg mounted at both ends of the bottom of the beams. Drive rollers are mounted at both ends between the two beams, the ends of the drive rollers being rotatably connected to the beams. A conveyor belt is mounted on the drive rollers, and the conveyor belt is located below the discharge pipe. A drive motor is mounted at one end of one of the drive rollers, and the drive motor is mounted on the beam. Multiple support rollers are mounted on the inner side of the conveyor belt, and the ends of the support rollers are rotatably connected to the beams. The natural alkaline old lake salt filling carrier placed on the conveyor belt is transported by the drive of the conveyor belt, thereby completing the loading and unloading operations of the carrier.

[0013] Furthermore, the clamping mechanism includes a first clamping plate and a second clamping plate. Both the first clamping plate and the second clamping plate are arc-shaped plates and are relatively arranged on both sides below the discharge pipe. The side of the second clamping plate away from the first clamping plate is installed with an electric push rod 3, and the electric push rod 3 is installed on the support frame. The side of the first clamping plate away from the second clamping plate is installed with a support shaft. The support shaft slides through the L-shaped frame, and the bottom of the L-shaped frame is fixed to the bottom of the support frame. The top of the L-shaped frame is threadedly connected with a locking bolt, and the end of the locking bolt corresponds to the support shaft. By bringing the first clamping plate and the second clamping plate closer together, the natural alkaline old lake salt filling carrier moved to the bottom of the discharge pipe can be relatively clamped, thereby ensuring the stability of the carrier during filling.

[0014] Furthermore, a guide shaft 2 is provided on the side of the electric push rod 3, one end of which is fixed to the second clamping plate, and the other end of which slides through the support frame. The guide shaft 2 guides the movement of the second clamping plate, ensuring that the second clamping plate and the first clamping plate are always aligned. BRIEF DESCRIPTION OF THE DRAWINGS
