Description

Technical Field

[0001] The present invention belongs to the technical field of knitting glove production equipment, and specifically relates to an automatic salt adding device and its process for an intelligent dipping production line of knitting gloves. Background Art

[0002] In the production process of knitting gloves, the dipping process plays a crucial role in enhancing the functionality and quality of gloves. As an important additive in the dipping process, the uniformity and accuracy of salt addition directly affect the performance of the dipping solution, and thus determine the quality and production efficiency of gloves.

[0003] However, the existing salt adding methods have many drawbacks. On the one hand, when adding salt, the salt is usually scattered out as a whole, and the uniform mixing is completely dependent on later stirring. This method not only consumes a large amount of time and energy, prolongs the production cycle, and increases the production cost, but also makes it difficult to ensure that the salt dissolves quickly and fully in the dipping solution, thus affecting the consistency and stability of glove dipping and resulting in uneven product quality; on the other hand, the existing salt adding method has a small salt scattering range, which is extremely easy to cause excessive local salt amount and form salt accumulation. The local salt aggregation will cause uneven concentration distribution of the dipping solution, resulting in different dipping effects on different parts of the gloves during the glove dipping process, reducing the product quality and increasing the defective rate.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: An automatic salt adding device for an intelligent dipping production line of knitting gloves, including a bath salt cover.

[0006] A pair of temporary storage hoppers filled with salt are installed on the side wall of the bath salt cover, and a blocking block is slidably installed at the discharge port of the temporary storage hopper. A salt scattering cover is horizontally slidably arranged inside the bath salt cover; A circumferential quantitative salt scattering component is installed inside the salt scattering cover. The circumferential quantitative salt scattering component includes a top plate inserted inside the salt scattering cover and a jacking groove for jacking the salt above the top plate to move. A guide plate is installed inside the salt scattering cover, and a number of pairs of arc-shaped guide protrusions are installed on the guide plate. A dial rod is rotatably installed at the center of the guide plate; A transmission component for driving the salt scattering cover to reciprocate is installed inside the bath salt cover. During the movement of the salt scattering cover, the top plate is driven to move and the dial rod rotates automatically to complete the circumferential quantitative salt scattering operation. After moving to one side of the temporary storage hopper, it squeezes through the blocking block to automatically complete the quantitative filling operation; A stirring component driven by the transmission component is also installed inside the bath salt cover.

[0007] As a preferred embodiment of the present invention, a substrate is installed at the bottom of the bath salt cover. A number of pairs of positioning holes for positioning connection are installed on the surface of the substrate.

One end of the positioning spring is clamped on the positioning plate, and the other end is clamped on the side wall of the sliding plate.

[0010] As a preferred embodiment of the present invention, the transmission assembly includes a shifting roller. A transmission shaft is installed at the rotation center of the shifting roller. The transmission shaft movably penetrates the side wall of the bath salt cover. The end of the transmission shaft is connected to the output end of a driving motor installed on the side wall of the bath salt cover. A cylindrical cam groove is formed on the surface of the shifting roller. A guiding slider is slidably arranged on the cylindrical cam groove. A guiding rod is movably penetrated inside the guiding slider, and both ends of the guiding rod are installed on the inner wall of the bath salt cover. A connecting rod is installed at the end of the guiding slider, and the connecting rod is connected to the side wall of the salt spreading cover. A top block is installed on the side wall of the transmission shaft, and the top block is used to drive the stirring assembly to stir.

[0011] As a preferred embodiment of the present invention, a pair of fixing plates are installed on the inner side wall of the bath salt cover. Lifting grooves and guiding grooves are respectively formed on the side walls of the pair of fixing plates. The lifting groove and the guiding groove are connected to each other. The guiding groove is a straight groove, and the lifting groove is an inclined groove. The guiding groove corresponds to the position of the discharge port of the temporary storage hopper. A sliding rod is slidably arranged inside the lifting groove. A top rod is installed on the sliding rod, and the top rod movably penetrates the salt spreading cover. The top of the top rod is connected to the top plate, and a partition plate is installed on the top rod. A compression spring is sleeved on the top rod. One end of the compression spring is clamped on the side wall of the salt spreading cover, and the other end is clamped on the partition plate.

[0012] As a preferred embodiment of the present invention, a positioning rack is installed inside one of the fixing plates. The length of the positioning rack is adapted to the horizontal length of the jacking groove. A positioning gear is meshed with the side wall of the positioning rack. A synchronous shaft is installed at the rotation center of the positioning gear. The synchronous shaft movably penetrates through the salt spreading cover and the top plate, and the end of the synchronous shaft is connected to a lever. The lever movably penetrates through a through hole formed on the surface of the guiding plate.

[0013] As a preferred embodiment of the present invention, a reset rod is installed at the bottom of the guiding plate. The bottom of the reset rod is movably inserted into a reset cover. The reset cover is installed at the bottom of the salt spreading cover and movably penetrates through the top plate. A pressing plate is slidably arranged in the cavity of the reset cover. The pressing plate is connected to the reset rod, and a reset spring is clamped between the cavity of the reset cover and the pressing plate. The compression direction of the reset spring and the moving direction of the pressing plate are on the same straight line.

[0014] As a preferred embodiment of the present invention, the stirring assembly includes a pair of stirring shafts. The pair of stirring shafts are rotatably installed on the side wall of the bath salt cover. Stirring plates are installed on each stirring shaft, and the stirring plates on different stirring shafts are arranged staggeredly. A torsion spring is clamped between the stirring shaft and the side wall of the bath salt cover. A rocker arm is installed on the stirring shaft, and the side wall of the rocker arm is in contact with the corresponding top block.

[0015] As a preferred embodiment of the present invention, the automatic salt adding process of an intelligent dipping production line for knitted gloves is as follows: Step 1: Start the driving motor. The motor drives the transmission shaft and the shifting roller to rotate. The cylindrical cam groove of the shifting roller drives the guiding slider to slide along the guiding rod. The salt spreading cover is driven to reciprocate in the bath salt cover through the connecting rod, accurately controlling the movement track of the salt spreading cover and improving the stability of the device. Step 2: When the salt spreading cover moves, the top block on the transmission shaft pushes the rocker arm of the stirring shaft, driving the stirring plate to stir the salt-containing butyl latex. The rotation of the stirring shaft deforms the torsion spring. After the top block disengages, the torsion spring drives the stirring shaft to rotate in the reverse direction, strengthening the stirring effect without additional power. Step 3: During the movement of the salt spreading cover, the sliding rod slides in the guiding groove and the jacking groove. When the sliding rod is in the guiding groove, the salt spreading cover fits against the discharge port of the temporary storage hopper, and the salt enters the salt spreading cover. After the sliding rod enters the jacking groove, the ejector rod pushes the top plate to rise, and the salt comes out from the through hole of the salt spreading cover, realizing the precise switching between feeding and salt spreading. Step 4: When the salt spreading cover slides in the jacking groove, the positioning rack meshes with the positioning gear, driving the lever to rotate. The lever drives the salt to rotate. When the salt hits the arc-shaped guiding protrusion, it scatters in all directions, expanding the salt spreading range and ensuring uniform salt spreading. Step 5: After the salt sprinkling cover completes the salt sprinkling cycle and returns to the initial position, the extrusion plugging block is separated from the connecting pipe. The salt sprinkling cover moves to the bottom of the connecting pipe. The guiding protrusion is pressed to drive the reset rod to compress the reset spring, and the sliding plate of the plugging block compresses the positioning spring, realizing quantitative filling of the salt sprinkling cover.

[0016] The present invention has the following beneficial effects compared with the prior art: During the salt sprinkling operation process of the present invention, continuous and efficient salt sprinkling is achieved. When the sliding rod enters the jacking groove, the jacking groove uses its inclined structure to push the sliding rod, driving the ejector rod and the top plate to rise. Salt is quantitatively ejected from the through holes of the salt sprinkling cover. In this way, the horizontal movement of the salt sprinkling cover is ingeniously converted into the lifting movement of the top plate, accurately realizing quantitative outward salt sprinkling and reducing the occurrence of excessive local salt content. At the same time, when the salt sprinkling cover slides in the jacking groove, the positioning rack and the positioning gear mesh with each other, driving the lever to rotate. The lever drives the salt to make a rotational movement. When the salt moves to the arc-shaped guiding protrusion, under the action of the guiding protrusion, the salt is dispersed around along a specific arc, greatly increasing the salt sprinkling range and making the salt distribution more uniform in the operation area, meeting the requirements of different scenarios for the salt sprinkling effect. At the same time, through the transmission component, the stirring component is linked, which not only avoids using an additional power source, simplifies the structure, reduces energy consumption and costs, but also through the reciprocating stirring of the stirring shaft, prevents the salt from getting damp and caking, maintains the fluidity of the salt, and ensures the continuous and efficient progress of the salt sprinkling action.

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0021] Embodiment 1: As Figures 1 to 10 shown, an automatic salt - adding device for an intelligent dipping production line of knitted gloves includes a bath salt cover 1.

[0022] A pair of temporary storage hoppers 12 filled with salt are installed on the side wall of the bath salt cover 1. Salt materials are stored in the hoppers. A plugging block 13 is slidably installed at the discharge port of the temporary storage hopper 12, and a salt - spreading cover 3 is horizontally slidably arranged inside the bath salt cover 1; A circumferential quantitative salt sprinkling component is installed inside the salt sprinkling cover 3. The circumferential quantitative salt sprinkling component includes a top plate 31 inserted inside the salt sprinkling cover 3 and a jacking groove 321 for jacking the movement of salt above the top plate 31. A guide plate 34 is installed inside the salt sprinkling cover 3, and a number of pairs of arc-shaped guide protrusions 342 are installed on the guide plate 34. A dial rod 333 is rotatably installed at the center of the guide plate 34; A transmission component for driving the salt sprinkling cover 3 to reciprocate is installed inside the bath salt cover 1. During the movement of the salt sprinkling cover 3, it drives the movement of the top plate 31 and the self-rotation of the dial rod 333 to complete the circumferential quantitative salt sprinkling operation. After moving to one side of the temporary storage hopper 12, it squeezes through the blocking block 13 to automatically complete the quantitative filling operation; A stirring component driven by the transmission component is also installed inside the bath salt cover 1.

[0023] As Figures 1 to 10 shown, a base plate 11 is installed at the bottom of the bath salt cover 1. A number of pairs of positioning holes 112 for positioning and connection are installed on the surface of the base plate 11. These positioning holes can be accurately docked with other equipment components, greatly improving the accuracy of the overall installation of the equipment, shortening the installation and debugging time, and reducing the installation technical threshold. A vertical plate 111 is installed on the base plate 11, and the vertical plate 111 is welded to the side wall of the bath salt cover 1.

[0024] As Figures 1 to 10 shown, further, a connecting plate 124 is installed on the side wall of the temporary storage hopper 12, and the connecting plate 124 is connected to the side wall of the bath salt cover 1, so that the temporary storage hopper 12 and the bath salt cover 1 form a stable overall structure, ensuring the stability of the salt material during temporary storage and transmission, and reducing the risk of salt material spilling or leaking; a cover plate 121 is installed on the top of the temporary storage hopper 12, a transmission pipe 122 is installed at the bottom of the temporary storage hopper 12, a connecting pipe 123 is installed at the end of the transmission pipe 122, and the connecting pipe 123 is mutually attached to the upper surface of the blocking block 13. The lower surface of the connecting pipe 123 is attached to the upper surface of the salt sprinkling cover 3, and the surface of the guide protrusion 342 close to the connecting pipe 123 is chamfered. This design greatly reduces the resistance when the salt sprinkling cover 3 is docked with the connecting pipe 123, so that the guide protrusion 342 can move downward after receiving the extrusion force, making the docking process smoother, improving the filling efficiency and accuracy of the salt sprinkling cover 3, and at the same time reducing the wear between components and extending the equipment maintenance cycle.

[0025] As Figures 1 to 10As shown in the figure, further, the plugging block 13 movably penetrates through the side wall of the bath salt cover 1. A fixing block 131 is installed on the side wall of the plugging block 13, a sliding plate 132 is installed on the side wall of the fixing block 131, positioning rods 134 are movably installed at both ends of the sliding plate 132, a base 133 is installed at the end of the positioning rods 134, the base 133 is installed on the side wall of the bath salt cover 1, a positioning plate 135 is installed at the top of the positioning rods 134, a positioning spring 136 is sleeved on the positioning rods 134, one end of the positioning spring 136 is clamped on the positioning plate 135, and the other end is clamped on the side wall of the sliding plate 132. This structural design enables the plugging block 13 to move flexibly under the action of an external force. After the external force disappears, it can quickly reset with the help of the elastic restoring force of the positioning spring 136, effectively ensuring the sealing effect at the connecting pipe 123, preventing salt material leakage, reducing material waste, and prolonging the service life of the plugging block 13.

[0026] Embodiment 2: The difference between this embodiment and Embodiment 1 is as follows: As Figures 1 to 10 shown in the figure, the transmission assembly includes a shifting roller 2. A transmission shaft 211 is installed at the rotation center of the shifting roller 2. The transmission shaft 211 movably penetrates through the side wall of the bath salt cover 1. The end of the transmission shaft 211 is connected to the output end of a driving motor 21 installed on the side wall of the bath salt cover 1. A cylindrical cam groove 22 is formed on the surface of the shifting roller 2. A guiding slider 221 is slidably arranged on the cylindrical cam groove 22. A guiding rod 222 movably penetrates through the inside of the guiding slider 221. Both ends of the guiding rod 222 are installed on the inner wall of the bath salt cover 1. A connecting rod 223 is installed at the end of the guiding slider 221, and the connecting rod 223 is connected to the side wall of the salt spreading cover 3. A top block 431 is installed on the side wall of the transmission shaft 211, and the top block 431 is used to drive the stirring assembly to stir. Compared with the traditional linear driving method, this driving method through the cooperation of the cylindrical cam groove and the guiding slider can accurately control the moving track and position of the salt spreading cover 3, significantly improving the stability and reliability of the device operation, enabling the salt spreading operation to be carried out strictly according to the preset path, reducing the deviation of the salt spreading position, and meeting the production scenarios with higher requirements for salt spreading accuracy.

[0027] As Figures 1 to 10As shown, in the specific implementation manner, a pair of fixing plates 32 are installed on the inner side wall of the bath salt cover 1. Lifting grooves 321 and guiding grooves 322 are respectively formed on the side walls of the pair of fixing plates 32. The lifting groove 321 and the guiding groove 322 are connected to each other. The guiding groove 322 is a straight groove, and the lifting groove 321 is an inclined groove. The guiding groove 322 corresponds to the position of the discharge port of the temporary storage hopper 12. Through the ingenious design of the lifting groove 321 and the guiding groove 322, the horizontal movement of the salt spreading cover 3 is converted into the lifting movement of the top plate 31, realizing the precise switching between feeding and discharging during the salt spreading process, greatly improving the coherence and efficiency of the salt spreading action, reducing the pauses and waiting time during the salt spreading process, and enhancing the overall working efficiency of the equipment. A sliding rod 314 is slidably arranged inside the lifting groove 321. A top rod 311 is installed on the sliding rod 314, and the top rod 311 movably penetrates through the salt spreading cover 3. The top of the top rod 311 is connected to the top plate 31, and a partition plate 312 is installed on the top rod 311. A compression spring 313 is sleeved on the top rod 311. One end of the compression spring 313 is clamped on the side wall of the salt spreading cover 3, and the other end of the compression spring 313 is clamped on the partition plate 312. After the sliding rod 314 enters the lifting groove 321, the inclined structure of the lifting groove 321 causes the sliding rod 314 to drive the top rod 311 to rise. The top rod 311 pushes the top plate 31 upward, and the compression spring 313 is compressed. The compression spring 313 facilitates the later reset operation.

[0028] As Figures 1 to 10 shown, further, a positioning rack 33 is installed inside one of the fixing plates 32. The length of the positioning rack 33 is adapted to the horizontal length of the lifting groove 321. A positioning gear 331 is meshed on the side wall of the positioning rack 33. A synchronous shaft 332 is installed at the rotation center of the positioning gear 331. The synchronous shaft 332 movably penetrates through the salt spreading cover 3 and the top plate 31, and the end of the synchronous shaft 332 is connected to a dial rod 333. The dial rod 333 movably penetrates through a through hole 341 formed on the surface of a guiding plate 34. During the process of the salt spreading cover 3 sliding in the lifting groove 321, the positioning rack 33 meshes with the positioning gear 331. The rotation of the positioning gear 331 drives the synchronous shaft 332 to rotate, and the synchronous shaft 332 drives the dial rod 333 to rotate. During the rotation process of the dial rod 333, it will contact the salt accumulated inside the salt spreading cover 3. Relying on its rotational motion characteristics, it drives the salt to perform a rotational motion outward. When the salt in the rotational motion state moves to the arc-shaped guiding protrusion 342 on the periphery of the salt spreading cover 3, the arc-shaped guiding protrusion 342 exerts a guiding effect on the salt due to its special arc. Under the action of the guiding protrusion 342, the salt rotates and disperses around along a specific arc, thereby greatly increasing the spreading range of the salt and ensuring that the salt spreading process can cover a larger area. Example 3: The difference between this example and Example 2 is: As Figures 1 to 10As shown in the figure, a reset rod 343 is installed at the bottom of the guide plate 34. The bottom of the reset rod 343 is movably inserted with a reset cover 344. The reset cover 344 is installed at the bottom of the salt spreading cover 3, and the reset cover 344 penetrates through the top plate 31 movably. A pressing plate 345 is slidably arranged in the inner cavity of the reset cover 344. The pressing plate 345 is connected to the reset rod 343. A reset spring 346 is clamped between the inner cavity of the reset cover 344 and the pressing plate 345. The compression direction of the reset spring 346 and the moving direction of the pressing plate 345 are on the same straight line. The cooperation of the reset spring 346 and related components enables the guide plate 34 to quickly reset after being pressed, ensuring the stable and reliable functions of the salt spreading cover 3 during continuous operation of the equipment, reducing equipment failures caused by the failure of components to reset in time, extending the service life of the equipment, and reducing the equipment maintenance cost.

[0029] As Figures 1 to 10 shown, in the specific implementation manner, the stirring assembly includes a pair of stirring shafts 4. The pair of stirring shafts 4 are rotatably installed on the side wall of the bath salt cover 1. Stirring plates 42 are installed on each stirring shaft 4, and the stirring plates 42 on different stirring shafts 4 are staggered. A torsion spring 41 is clamped between the stirring shaft 4 and the side wall of the bath salt cover 1. A rocker arm 43 is installed on the stirring shaft 4, and the side wall of the rocker arm 43 is in contact with the corresponding top block 431. The staggered stirring plates 42 increase the stirring area and improve the stirring effect. By means of the transmission shaft to link the stirring assembly and using the torsion spring 41 to realize the reciprocating rotation of the stirring shaft 4, no additional power source is required. This not only simplifies the device structure, reduces the complexity and maintenance cost of the equipment, but also reduces energy consumption, meeting the development requirements of energy conservation and environmental protection.

[0030] The present invention also discloses an automatic salt adding process for a knitting glove intelligent dipping production line, and the steps are as follows: Step 1: Start the driving motor 21. The motor drives the transmission shaft 211 and the shifting roller 2 to rotate. The cylindrical cam groove 22 of the shifting roller 2 drives the guide slider 221 to slide along the guide rod 222, and drives the salt spreading cover 3 to reciprocate in the bath salt cover 1 through the connecting rod 223, accurately controlling the movement track of the salt spreading cover and improving the stability of the device; Step 2: When the salt spreading cover 3 moves, the top block 431 on the transmission shaft 211 pushes the rocker arm 43 of the stirring shaft 4, driving the stirring plate 42 to stir the salt-containing butyl rubber latex. The rotation of the stirring shaft 4 deforms the torsion spring 41. After the top block 431 disengages, the torsion spring 41 drives the stirring shaft 4 to rotate in the reverse direction, strengthening the stirring effect and without additional power; Step 3: During the movement of the salt spreading cover 3, the sliding rod 314 slides in the guide groove 322 and the lifting groove 321. When the sliding rod 314 is in the guide groove 322, the salt spreading cover 3 fits against the discharge port of the temporary storage hopper 12, and salt enters the salt spreading cover 3. After the sliding rod 314 enters the lifting groove 321, the ejector rod 311 pushes the top plate 31 to rise, and the salt comes out from the through hole 341 of the salt spreading cover 3, realizing the precise switching between feeding and salt spreading; Step 4: When the salt - spreading cover 3 slides in the lifting groove 321, the positioning rack 33 meshes with the positioning gear 331, driving the lever 333 to rotate. The lever 333 drives the salt to rotate. After the salt hits the arc - shaped guiding protrusion 342, it scatters in all directions, expanding the salt - spreading range and ensuring uniform salt spreading. Step 5: When the salt - spreading cover 3 completes the salt - spreading cycle and returns to the initial position, it squeezes the blocking block 13 to separate it from the connecting pipe 123. The salt - spreading cover 3 moves to the bottom of the connecting pipe 123. The guiding protrusion 342 is pressed to drive the reset rod 343 to compress the reset spring 346, and the sliding plate 132 of the blocking block 13 compresses the positioning spring 136, realizing quantitative filling of the salt - spreading cover 3.

[0031] An automatic salt - adding device for an intelligent dipping glue production line of knitted gloves according to the present invention aims to accurately add salt into the butadiene latex in the bath salt cover 1. The specific implementation principle is as follows: When salt needs to be added to the butadiene latex in the bath salt cover 1, the operator first starts the transmission component. By starting the driving motor 21, the drive shaft 211 is driven to rotate. The rotation of the drive shaft 211 causes the shifting roller 2 to rotate synchronously. The cylindrical cam groove 22 on the surface of the shifting roller 2 changes synchronously. Through a specific shape, the guiding slider 221 is driven to slide along the guiding rod 222, and the salt - spreading cover 3 is driven to move reciprocally through the connecting rod 223. This transmission method using the cylindrical cam groove and the guiding slider can accurately control the movement trajectory and position of the salt - spreading cover 3. Compared with the traditional simple linear drive, it significantly improves the stability and reliability of the device operation, ensuring that the salt - spreading operation moves along the preset path.

[0032] During the movement of the salt - spreading cover 3, the top block 431 installed on the side wall of the drive shaft 211 rotates synchronously. The top block 431 contacts and pushes the rocker arm 43 on the stirring shaft 4, causing the stirring shaft 4 to rotate. The stirring plate 42 installed on the stirring shaft 4 stirs the salt in the bath salt cover 1 to prevent the salt from caking. At the same time, when the stirring shaft 4 rotates, the torsion spring 41 undergoes elastic deformation. After the top block 431 disengages from the rocker arm 43, the torsion spring 41 drives the stirring shaft 4 to rotate in the reverse direction, realizing the reciprocating rotation of the stirring shaft 4 and enhancing the stirring effect. By linking the stirring component with the drive shaft, no additional power source is required, which not only simplifies the device structure but also reduces energy consumption and equipment costs. The reciprocating stirring of the stirring shaft ensures the fluidity of the salt, providing a guarantee for the subsequent smooth salt - spreading into the butadiene latex.

[0033] While the salt spreading cover 3 moves, the sliding rod 314 slides within the lifting groove 321 and the guiding groove 322. When the sliding rod 314 slides within the guiding groove 322, the salt spreading cover 3 is then in contact with the connecting pipe 123 at the bottom of the temporary storage hopper 12. The salt within the temporary storage hopper 12 enters the salt spreading cover 3 through the transfer pipe 122 and the connecting pipe 123. As the salt spreading cover 3 continues to move, the sliding rod 314 enters the lifting groove 321. The inclined structure of the lifting groove 321 causes the sliding rod 314 to drive the ejector rod 311 upward. The ejector rod 311 pushes the top plate 31 upward, compressing the compression spring 313. The compression spring 313 facilitates the subsequent reset operation. Among them, due to the push of the top plate 31, the salt within the salt spreading cover 3 begins to move towards the upper surface of the salt spreading cover 3 and finally exits through the through hole 341. This design, by means of the cooperation of the lifting groove and the guiding groove, ingeniously converts the horizontal movement of the salt spreading cover 3 into the lifting movement of the top plate 31, realizing the precise switching between feeding and discharging during the salt spreading process, and ensuring the coherence and efficiency of the salt spreading action.

[0034] During this process (when the salt spreading cover 3 slides within the lifting groove 321), the positioning rack 33 meshes with the positioning gear 331. The rotation of the positioning gear 331 drives the synchronous shaft 332 to rotate, and the synchronous shaft 332 drives the lever 333 to rotate. During the rotation of the lever 333, it will come into contact with the salt accumulated within the salt spreading cover 3. Relying on its rotating motion characteristics, it drives the salt to move outward in a rotational motion. When the salt in the rotational motion state moves to the arc-shaped guiding protrusion 342 on the periphery of the salt spreading cover 3, the arc-shaped guiding protrusion 342 exerts a guiding effect on the salt due to its special curvature. Under the action of the guiding protrusion 342, while rotating, the salt moves radially outward along a specific arc, thereby greatly increasing the spreading range of the salt, ensuring that the salt spreading process can cover a larger area, and improving the efficiency and uniformity of the automatic salt adding device during the salt adding operation. The meshing of the positioning rack 33 and the positioning gear 331 ensures the precise synchronization of the rotation of the lever 333 and the movement of the salt spreading cover 3, enhancing the synergy of the system. The cooperation between the lever 333 and the arc-shaped guiding protrusion 342 breaks through the limitations of the traditional salt spreading method, significantly increases the salt spreading area, makes the salt more evenly distributed within the working area, and meets the requirements for the salt spreading effect in different scenarios.

[0035] When the salt spreading cover 3 completes a full salt spreading cycle and returns to the initial position, the salt spreading cover 3 presses against the plugging block 13. After being pressed, the plugging block 13 slowly separates from the connecting pipe 123, and the salt spreading cover 3 can move to the bottom of the connecting pipe 123, where there is no gap between the plugging block 13 and the side wall of the salt spreading cover 3, so that salt will not leak. When the salt spreading cover 3 moves, the chamfered guiding protrusion 342 on the salt spreading cover 3 is pressed to slide downward, and the reset rod 343 at the bottom of the guiding plate 34 is driven to move along with the guiding plate 34. The bottom of the reset rod 343 moves within the reset cover 344, causing the pressing plate 345 to compress the reset spring 346, which facilitates later resetting. With continuous movement, finally the salt spreading cover 3 slides to the bottom of the connecting pipe 123. When the plugging block 13 slides, the sliding plate 132 on the side wall of the plugging block 13 moves along the positioning rod 134 at this time and compresses the positioning spring 136 on the surface of the positioning plate 135, which facilitates later resetting through the positioning spring 136.
