[0002] The adjustable feeding structure for pickling additive production is a device that can control the amount of raw materials conveyed for pickling additives, and can flexibly adjust the feeding speed and amount according to production needs.

[0003] To address the aforementioned issues, existing patents offer solutions, but the existing feeding structures lack a structure that allows for the adjustment and conversion of the storage tank. This necessitates replacing or cleaning the storage tank when switching to produce pickling additives with different formulations to prevent cross-contamination of different raw materials, thereby reducing the continuous operation capability of the production line.

[0004] Therefore, an adjustable feeding structure for the production of pickling additives is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable feeding structure for the production of pickling additives, which solves the problem that existing pickling additive production lacks an adjustable and convertible storage tank structure. This results in the need to replace or clean the storage tank when switching to produce pickling additives with different formulations, thus avoiding cross-contamination of different raw materials and reducing the continuous operation capability of the production line.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable feeding structure for pickling additive production, comprising a conveyor belt, an adjustment mechanism welded to the top of the conveyor belt, and a feeding mechanism welded to the surface of the adjustment mechanism. The adjustment mechanism includes four support rods, a support shell, a lead screw, a limit rod, a servo motor, two threaded blocks, two sliders, and a PLC controller. The support rods are welded to the top of the conveyor belt. The left support shell is welded to the top of the left rear support rod and the left front support rod, and the right support shell is welded to the top of the right rear support rod and the right front support rod. The lead screw is rotatably connected to the inside of the left support shell, and the limit rod is welded to the inside of the right support shell. The servo motor is installed on the rear side of the left support shell, and a connecting shaft is connected to the rear side of the lead screw via a flat key.

[0007] Preferably, the output end of the servo motor passes through the support shell and is fixedly connected to the rear side of the connecting shaft; the threaded block is threadedly connected to the surface of the lead screw; the slider is slidably connected to the surface of the limit rod; and the PLC controller is installed on the right front side of the conveyor belt.

[0008] Preferably, the feeding mechanism includes four connecting rods, three storage bins, a fixed rod, a discharge hopper, a discharge pipe, and a flow regulating valve. The connecting rods are respectively welded to the right side of the two threaded blocks and the left side of the two sliders.

[0009] Preferably, the storage bin is welded to the side of the connecting rod away from the threaded block and the slider, and the fixing rod is welded between adjacent storage bins.

[0010] Preferably, the hopper is welded to the bottom of the storage box, the discharge pipe is fixedly connected to the bottom of the hopper, and the flow regulating valve is installed on the surface of the discharge pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The adjustment mechanism of this application uses a servo motor as a power source and drives the lead screw to rotate through the connecting shaft connected by a flat key. With the threaded transmission relationship between the threaded block and the lead screw, the feeding mechanism can move smoothly. The limit rod and the slider in the right support shell form a guiding constraint, which effectively prevents the threaded block from shifting with the lead screw rotation, ensuring that the movement trajectory of the feeding mechanism is controllable. This allows the feeding mechanism to adjust its position according to the feeding requirements of the conveyor belt, solving the problem that the traditional feeding structure has a fixed position and cannot adapt to multiple working conditions. The PLC controller realizes intelligent control of the servo motor. The operator does not need to adjust it manually. The start, stop, speed and rotation direction of the servo motor can be set by the PLC controller, thereby controlling the movement speed and position of the feeding mechanism.

[0016] 2. The feeding mechanism of this application is equipped with three independent storage bins, which can store different components of pickling additives respectively. They are fixedly connected to the threaded blocks and sliders of the adjusting mechanism through connecting rods, so as to realize the synchronous movement and positioning of multiple storage bins. There is no need to frequently change the storage device, which improves the overall production efficiency. The discharge hopper welded to the bottom of the storage bin adopts a funnel-shaped structure, which can guide the raw materials to be discharged in a concentrated manner and avoid the accumulation and residue of raw materials at the bottom of the storage bin. The flow regulating valve installed on the discharge pipe can control the discharge amount of each component raw material according to the production formula requirements, ensuring accurate raw material ratio and reducing raw material waste caused by flow control failure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] An adjustable feeding structure for pickling additive production includes a conveyor belt 1, an adjustment mechanism 2 welded to the top of the conveyor belt 1, and a feeding mechanism 3 welded to the surface of the adjustment mechanism 2. The adjustment mechanism 2 includes four support rods 21, a support shell 22, a lead screw 23, a limit rod 24, a servo motor 25, two threaded blocks 26, two sliders 27, and a PLC controller 28. The support rods 21 are welded to the top of the conveyor belt 1. The left support shell 22 is welded to the top of the left rear support rod 21 and the left front support rod 21. The right support shell 22 is welded to the top of the right rear support rod 21 and the right front support rod 21. The lead screw 23 is rotatably connected to the inside of the left support shell 22. The limit rod 24 is welded to the inside of the right support shell 22. The servo motor 25 is installed on the rear side of the left support shell 22. The rear side of the lead screw 23 is connected to a connecting shaft via a flat key.

[0026] In this embodiment: the conveyor belt 1 supports and limits the adjustment mechanism 2, and also has continuous conveying capability, which can transport the pickling additive raw materials discharged from the feeding mechanism 3 to the downstream production stage. The support rod 21 stably supports the support shell 22 above the conveyor belt 1. The support shell 22 supports and limits the lead screw 23, servo motor 25 and limit rod 24. The screw 23 and the threaded block 26 form a helical transmission structure, which converts the rotational motion of the servo motor 25 into the linear motion of the threaded block 26, thereby driving the feeding mechanism 3 to achieve position adjustment. The limit rod 24 slides against the slider 27. The connection provides stable guidance for the movement of the feeding mechanism 3. The servo motor 25 is rigidly connected to the lead screw 23 through the connecting shaft, which can accurately output power to drive the lead screw 23 to rotate. The threaded block 26 is sleeved on the surface of the lead screw 23 through the threaded connection, which converts the rotational motion of the lead screw 23 into its own linear motion, thereby driving the connecting rod 31 welded to it and the feeding mechanism 3 to move synchronously. The slider 27 provides stable support for the right side of the feeding mechanism 3. The PLC controller 28 can preset the control program to realize the control of the start, stop, speed and direction of the servo motor 25, thereby automatically adjusting the position of the feeding mechanism 3 and reducing manual operation intervention.

[0027] Specifically, such as Figure 2 , Figure 3 As shown, the output end of the servo motor 25 passes through the support shell 22 and is fixedly connected to the rear side of the connecting shaft. The threaded block 26 is threadedly connected to the surface of the lead screw 23. The slider 27 is slidably connected to the surface of the limit rod 24. The PLC controller 28 is installed on the right front side of the conveyor belt 1.

[0028] Specifically, such as Figure 4 As shown, the feeding mechanism 3 includes four connecting rods 31, three storage boxes 32, a fixed rod 33, a discharge hopper 34, a discharge pipe 35, and a flow regulating valve 36. The connecting rods 31 are respectively welded to the right side of the two threaded blocks 26 and the left side of the two sliders 27.

[0029] Specifically, such as Figure 4 As shown, the storage box 32 is welded to the side of the connecting rod 31 away from the threaded block 26 and the slider 27, and the fixing rod 33 is welded between adjacent storage boxes 32.

[0030] In this embodiment: the feeding mechanism 3 is stably fixed to the adjusting mechanism 2 by setting the connecting rod 31, ensuring that the power of the adjusting mechanism 2 can be transmitted to the feeding mechanism 3. The three storage boxes 32 can store different components of pickling additive raw materials respectively, realizing the classified storage of multi-component raw materials, avoiding cross-contamination of raw materials, and ensuring the purity of raw materials. They are connected to the adjusting mechanism 2 by the connecting rod 31 and can move synchronously with the adjusting mechanism 2 to ensure accurate discharge position. The fixing rod 33 connects the three independent storage boxes 32 into an integrated structure, enhancing the overall rigidity and stability of the feeding mechanism 3. The hopper 34 adopts a funnel-shaped structure design with a smooth inner wall and an inclined angle, which can guide the raw materials in the storage boxes 32 to flow to the discharge pipe 35, avoiding the accumulation and residue of raw materials at the bottom of the storage boxes 32 and reducing raw material loss. The discharge pipe 35 can make the raw materials fall vertically to the conveyor belt 1, avoiding raw material splashing and reducing material loss. The flow regulating valve 36 can control the discharge flow rate and rate of raw materials in each storage box 32 by adjusting the valve opening according to the formula requirements of the pickling additive, ensuring that the raw materials are fed in proportion.

[0031] Specifically, such as Figure 4 As shown, the feeding hopper 34 is welded to the bottom of the storage box 32, the discharge pipe 35 is fixedly connected to the bottom of the feeding hopper 34, and the flow regulating valve 36 is installed on the surface of the discharge pipe 35.

[0032] Specifically, such as Figure 5 As shown, reinforcing rings 4 are welded to both sides of the fixing rod 33, and the surface of the reinforcing rings 4 is coated with anti-corrosion paint.

[0033] In this embodiment: by setting a reinforcing ring 4, the contact area between the fixing rod 33 and the storage box 32 is increased through the ring structure, so that the force of the fixing rod 33 is transmitted to the storage box 32 more evenly, further strengthening the connection strength between adjacent storage boxes 32. By setting an anti-corrosion coating, the chemical corrosion of pickling additive raw materials can be effectively resisted, and the service life of the reinforcing ring 4 and the fixing rod 33 can be extended.

[0034] Specifically, such as Figure 5 As shown, support columns 5 are welded to both sides of the bottom of the support shell 22, and anti-slip textures are engraved on the bottom of the support columns 5.

[0035] Specifically, such as Figure 5 As shown, a sealing cover 6 is rotatably connected to the top of the storage box 32, and a handle 7 is welded to the top of the sealing cover 6.

[0036] In this embodiment: by setting support columns 5, the load transmitted by the support shell 22 is distributed, and the overall support stability of the adjustment mechanism 2 is improved. By setting anti-slip texture, the friction between the material and the ground is increased. By setting a sealing box cover 6, the opening of the storage box 32 can be sealed and opened. When closed, it can effectively isolate external air, dust and moisture from entering the storage box 32, and prevent the raw materials from getting damp, clumping, oxidizing and deteriorating or being contaminated. By setting a handle 7, a convenient force point is provided for the operator to open or close the sealing box cover 6.

[0037] Working Principle: First, the operator opens the sealed box cover 6 using handle 7 and loads the different components of the pickling additive into three independent storage boxes 32. After loading, the sealed box cover 6 is closed. Next, the operator presets parameters through the PLC controller 28 and sends a control signal to the servo motor 25. After the servo motor 25 starts, its front output end drives the lead screw 23 inside the left support shell 22 to rotate smoothly through the connecting shaft that passes through the support shell 22. Since the threaded block 26 is threadedly connected to the lead screw 23, and the limiting rod 24 inside the right support shell 22 forms a guiding constraint on the feeding mechanism 3 through the slider 27, the rotational motion of the lead screw 23 is converted into the linear motion of the threaded block 26. The slider 27 slides synchronously along the limiting rod 24, driving the feeding mechanism 3 fixed thereto to move as a whole through the connecting rod 31 until the discharge pipe 35 at the bottom of the storage box 32 is aligned with the feeding area of ​​the conveyor belt 1. The PLC controller 28 controls the servo motor 25 to stop, completing the position adjustment. Then, the operator... According to the preset formula parameters in the PLC controller 28, the operator adjusts the opening of the flow regulating valve 36. The raw materials in the storage tank 32 flow into the bottom discharge hopper 34 under the action of gravity. The funnel-shaped structure of the discharge hopper 34 guides the raw materials to flow to the discharge pipe 35, avoiding the accumulation of raw materials at the bottom of the storage tank 32. After the raw materials are controlled by the flow regulating valve 36, they fall vertically onto the conveyor belt 1 below through the discharge pipe 35. Afterwards, when it is necessary to change the raw materials, the operator controls the servo motor 25 to start again through the PLC controller 28 to switch the storage tank 32. Then, after the conveyor belt 1 starts, it transports the mixed raw materials on the surface to the downstream production stage at a uniform speed. Finally, after a batch of production is completed, the operator controls the servo motor 25 to reverse through the PLC controller 28, driving the feeding mechanism 3 back to the initial position. The operator then opens the sealing box cover 6 again through the handle 7 to replenish the raw materials, or cleans the storage tank 32 and the discharge hopper 34 to prepare for the next batch of production.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
