Abstract

The present invention relates to the technical field of knitted glove production equipment, and discloses an automatic salt adding device and process for an intelligent dipping production line for knitted gloves, comprising a bath salt hood, a salt spreading hood, a circumferential quantitative salt spreading assembly, a transmission assembly, and a stirring assembly. The present invention realizes continuous and efficient salt spreading during the salt spreading operation. When the sliding rod enters the lifting trough, the lifting trough pushes the sliding rod by virtue of its inclined structure, driving the top rod and the top plate to rise, and the salt is quantitatively pushed out from the through hole of the salt spreading hood. In this way, the horizontal movement of the salt spreading hood is cleverly converted into the lifting movement of the top plate, and the quantitative outward salt spreading is accurately achieved, reducing the occurrence of excessive local content. Moreover, when the salt spreading hood slides in the lifting trough, the positioning rack and the positioning gear engage with each other, driving the shifting rod to rotate, and the shifting rod drives the salt to rotate. When the salt moves to the arc-shaped guide protrusion, under the action of the guide protrusion, the salt is dispersed to the surroundings along a specific arc, greatly increasing the salt spreading range and making the salt more evenly distributed in the operating area.

Description

Technical Field

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

[0002] In the production of knitted gloves, the dipping process plays a crucial role in enhancing the functionality and quality of the gloves. Salt, a crucial additive in the dipping process, is used uniformly and precisely, directly impacting the properties of the dipping solution and, in turn, determining glove quality and production efficiency.

[0003] However, existing salting methods have numerous drawbacks. First, salt is typically sprinkled outward in a single mass, relying entirely on subsequent stirring to achieve uniform mixing. This method not only consumes significant time and energy, prolongs production cycles, and increases production costs, but also makes it difficult to ensure rapid and complete dissolution of the salt in the dipping solution, thereby impacting the consistency and stability of glove dipping and leading to inconsistent product quality. Furthermore, existing salting methods have a narrow salting range, making it prone to localized excess salt accumulation, which can lead to uneven concentration distribution in the dipping solution. This results in varying dipping results in different glove areas during the dipping process, reducing product quality and increasing the defective rate. It is with these considerations that the present invention was developed. Summary of the Invention

[0017] As a preferred embodiment of the present invention, the stirring assembly includes a pair of stirring shafts, which are rotatably mounted on the side walls 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.

[0018] As a preferred embodiment of the present invention, the automatic salting process of the intelligent dipping production line for knitted gloves comprises the following steps:

[0019] Step 1: Start the drive motor, which drives the transmission shaft and the shift roller to rotate. The cylindrical cam groove of the shift roller drives the guide slider to slide along the guide rod, and drives the salt spreader to move back and forth in the bath salt cover through the connecting rod, accurately controlling the movement trajectory of the salt spreader and improving the stability of the device.

[0020] Step 2: When the salt hood moves, the top block on the drive 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 is separated, the torsion spring drives the stirring shaft to rotate in the opposite direction, enhancing the stirring effect without the need for additional power.

[0021] Step 3: During the movement of the salt spreading hood, the slide rod slides in the guide groove and the lifting groove. When the slide rod is in the guide groove, the salt spreading hood fits the discharge port of the temporary storage hopper, and the salt enters the salt spreading hood. After the slide rod enters the lifting groove, the ejector rod pushes the top plate up, and the salt comes out from the through hole of the salt spreading hood, realizing the precise switching between feeding and salt spreading;

[0022] Step 4: When the salt spreading cover slides in the lifting groove, the positioning rack engages with the positioning gear, driving the lever to rotate, and the lever drives the salt to rotate. After the salt hits the arc-shaped guide protrusion, it spreads to the surrounding area, expanding the salt spreading range and ensuring uniform salt spreading;

[0023] Step 5: The salt spreading hood returns to its initial position after completing the salt spreading cycle, and the sealing block is squeezed to separate it from the connecting pipe. The salt spreading hood moves to the bottom of the connecting pipe. The guide protrusion is pressed to drive the reset rod to compress the reset spring, and the slide of the sealing block compresses the positioning spring to achieve quantitative filling of the salt spreading hood.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention realizes the continuous and efficient salt spreading during the salt spreading operation. When the sliding rod enters the lifting trough, the lifting trough pushes the sliding rod by means of the inclined structure, driving the top rod and the top plate to rise, and the salt is pushed out quantitatively from the through hole of the salt spreading cover, thereby cleverly converting the horizontal movement of the salt spreading cover into the lifting movement of the top plate, accurately achieving the quantitative outward salt spreading and reducing the occurrence of excessive salt content in the local area. At the same time, when the salt spreading cover slides in the lifting trough, the positioning rack and the positioning gear engage with each other, driving the shifting rod to rotate, and the shifting rod drives the salt to rotate. When the salt moves to the arc-shaped guide protrusion, under the action of the guide protrusion, the salt is dispersed to the surrounding areas along a specific arc, greatly increasing the salt spreading range, making the salt more evenly distributed in the working area, and meeting the requirements of the salt spreading effect in different scenarios. At the same time, the stirring assembly is linked by the transmission assembly, which not only avoids the use of an additional power source, simplifies the structure, reduces energy consumption and cost, but also prevents the salt from getting damp and agglomerating through the reciprocating stirring of the stirring shaft, maintains the fluidity of the salt, and ensures the continuous and efficient salt spreading operation. The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0043] Example 1: Figures 1 to 10As shown, an automatic salt adding device for an intelligent dipping production line for knitted gloves includes a bath salt cover 1.

[0044] A pair of temporary storage hoppers 12 filled with salt are installed on the side wall of the bath salt cover 1. The salt material is stored in the hoppers. A blocking block 13 is slidably installed at the discharge port of the temporary storage hopper 12. A salt spreading cover 3 is horizontally slidably provided inside the bath salt cover 1.

[0045] A circumferential quantitative salt spreading assembly is installed inside the salt spreading hood 3. The circumferential quantitative salt spreading assembly includes a top plate 31 inserted into the salt spreading hood 3 and a lifting groove 321 for lifting the salt above the top plate 31. A guide plate 34 is installed inside the salt spreading hood 3, and a plurality of pairs of arc-shaped guide protrusions 342 are installed on the guide plate 34. A lever 333 is rotatably installed at the center of the guide plate 34.

[0046] The bath salt cover 1 is internally provided with a transmission assembly for driving the salt spreading cover 3 to slide back and forth. During the movement, the salt spreading cover 3 drives the top plate 31 to move and the lever 333 to rotate, thereby completing the circumferential quantitative salt spreading operation. After moving to one side of the temporary storage hopper 12, the sealing block 13 is squeezed to automatically complete the quantitative filling operation.

[0047] A stirring assembly driven by a transmission assembly is also installed inside the bath salt cover 1.

[0048] like Figures 1 to 10 As shown, a base plate 11 is installed at the bottom of the bath salt cover 1, and several 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 lowering 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.

[0049] like Figures 1 to 10 As shown, further, a connecting plate 124 is installed on the side wall of the temporary storage hopper 12, and the connecting plate 124 is interconnected with 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 the temporary storage and transmission process, 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, and 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 fitted with the upper surface of the blocking block 13, and the lower surface of the connecting pipe 123 is fitted with the upper surface of the salt spreading cover 3, and the surface of the guide protrusion 342 close to the side of the connecting pipe 123 is chamfered. This design greatly reduces the resistance when the salt spreading cover 3 and the connecting pipe 123 are docked, so that the guide protrusion 342 can move downward after receiving the extrusion force, making the docking process smoother, improving the efficiency and accuracy of the salt spreading cover 3 filling, while reducing wear between components and extending the equipment maintenance cycle.

[0050] like Figures 1 to 10As shown, further, the blocking block 13 is movable through the side wall of the bath salt cover 1, and a fixed block 131 is installed on the side wall of the blocking block 13. A slide 132 is installed on the side wall of the fixed block 131. Positioning rods 134 are movably installed at both ends of the slide 132. A base 133 is installed at the end of the positioning rod 134. The base 133 is installed on the side wall of the bath salt cover 1. A positioning plate 135 is installed on the top of the positioning rod 134. A positioning spring 136 is sleeved on the positioning rod 134. One end of the positioning spring 136 is clamped to the positioning plate 135, and the other end is clamped to the side wall of the slide 132. This structural design allows the blocking block 13 to move flexibly under the action of an external force. After the external force disappears, it is 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 leakage, reducing material waste, and extending the service life of the blocking block 13.

[0051] Example 2: Based on Example 1, the difference from this example is that: Figures 1 to 10 As shown, the transmission assembly includes a shift roller 2, a transmission shaft 211 is installed at the rotation center of the shift roller 2, the transmission shaft 211 movably penetrates the side wall of the bath salt cover 1, and the end of the transmission shaft 211 is connected to the output end of the drive motor 21 installed on the side wall of the bath salt cover 1, and a cylindrical cam groove 22 is opened on the surface of the shift roller 2, and a guide slider 221 is slidably provided on the cylindrical cam groove 22, and a guide rod 222 is movably installed inside the guide slider 221, and both ends of the guide rod 222 are installed on the inner wall of the bath salt cover 1, and a connecting rod 223 is installed at the end of the guide slider 221, and the connecting rod 223 is connected to the side wall of the salt spreading cover 3, and 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 drive method, this transmission method through the cooperation of the cylindrical cam groove and the guide slider can accurately control the moving trajectory and position of the salt spreading hood 3, significantly improve the stability and reliability of the device operation, make the salt spreading operation strictly follow the preset path, reduce the salt spreading position deviation, and meet the production scenarios with high requirements for salt spreading accuracy.

[0052] like Figures 1 to 10As shown, in a specific embodiment, a pair of fixing plates 32 are installed on the inner side wall of the bath salt cover 1, and a pair of fixing plates 32 side walls are respectively provided with a lifting groove 321 and a guide groove 322, the lifting groove 321 and the guide groove 322 are connected to each other, and the guide groove 322 is a straight groove, and the lifting groove 321 is an inclined groove, and the guide groove 322 corresponds to the discharge port position of the temporary storage bucket 12. Through the ingenious design of the lifting groove 321 and the guide groove 322, the horizontal movement of the salt spreading cover 3 is converted into the lifting movement of the top plate 31, so that the precise switching of feeding and discharging during the salt spreading process is realized, which greatly improves the consistency and efficiency of the salt spreading action, reduces the pause and waiting time during the salt spreading process, and improves the overall working efficiency of the equipment. The lifting groove 321 is provided with a sliding rod 314 for sliding inside, and a push rod 311 is installed on the sliding rod 314, and the push rod 311 movably passes through the salt spreading hood 3, the top of the push rod 311 and the top plate 31 are connected to each other, and a partition 312 is installed on the push rod 311, and a compression spring 313 is sleeved on the push rod 311, one end of the compression spring 313 is clamped on the side wall of the salt spreading hood 3, and the other end of the compression spring 313 is clamped on the partition 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 push rod 311 to rise, and the push rod 311 pushes the top plate 31 to move upward, and the compression spring 313 is compressed, and the compression spring 313 facilitates the later reset operation.

[0053] like Figures 1 to 10 As shown, a positioning rack 33 is mounted within one of the fixed plates 32. The length of the positioning rack 33 matches the horizontal length of the lifting slot 321. A positioning gear 331 is meshed with the sidewall of the positioning rack 33. A synchronization shaft 332 is mounted at the rotation center of the positioning gear 331. The synchronization shaft 332 movably extends through the salt spreading hood 3 and the top plate 31. The end of the synchronization shaft 332 is connected to a lever 333, which movably extends through a through-hole 341 defined in the surface of the guide plate 34. As the salt spreading hood 3 slides within the lifting slot 321, the positioning rack 33 and the positioning gear 331 mesh with each other. The rotation of the positioning gear 331 drives the synchronization shaft 332, which in turn drives the lever 333. During rotation, the lever 333 contacts the salt accumulated within the salt spreading hood 3 and, due to its rotational characteristics, drives the salt to rotate outward. When the salt in a rotating state moves to the arc-shaped guide protrusions 342 around the salt spreading cover 3, the arc-shaped guide protrusions 342 guide the salt with their special curvature. Under the action of the guide protrusions 342, the salt is dispersed along a specific arc while rotating, thereby greatly increasing the salt spreading range and ensuring that the salt spreading process can cover a larger area.

[0054] Example 3: Based on Example 2, the difference from this example is that: Figures 1 to 10As shown, a reset rod 343 is mounted at the bottom of the guide plate 34. A reset cover 344 is movably connected to the bottom of the reset rod 343. The reset cover 344 is mounted at the bottom of the salt spreading hood 3 and movably extends through the top plate 31. A pressure plate 345 is slidably disposed within the inner cavity of the reset cover 344. The pressure plate 345 is interconnected with the reset rod 343. A reset spring 346 is clamped between the inner cavity of the reset cover 344 and the pressure plate 345. The compression direction of the reset spring 346 and the movement direction of the pressure plate 345 are aligned. The coordination of the reset spring 346 and related components allows the guide plate 34 to quickly reset after being compressed, ensuring that the various functions of the salt spreading hood 3 are stable and reliable during continuous operation of the equipment, reducing equipment failures caused by the failure of components to reset in a timely manner, extending the equipment's service life, and reducing equipment maintenance costs.

[0055] like Figures 1 to 10 As shown, in a specific embodiment, the stirring assembly includes a pair of stirring shafts 4, a pair of stirring shafts 4 are rotatably mounted on the side wall of the bath salt cover 1, each stirring shaft 4 is mounted with a stirring plate 42, and the stirring plates 42 on different stirring shafts 4 are staggered, and a torsion spring 41 is provided between the stirring shaft 4 and the side wall of the bath salt cover 1, and a rocker arm 43 is mounted on the stirring shaft 4, and the side wall of the rocker arm 43 fits with the corresponding top block 431. The staggered stirring plates 42 increase the stirring area and enhance the stirring effect. With the help of the transmission shaft linkage stirring assembly, the torsion spring 41 is used to realize the reciprocating rotation of the stirring shaft 4 without the need for an additional power source. This not only simplifies the device structure, reduces the complexity and maintenance cost of the equipment, but also reduces energy consumption, which meets the development requirements of energy conservation and environmental protection.

[0056] The present invention also discloses an automatic salting process for an intelligent dipping production line for knitted gloves, which comprises the following steps:

[0057] Step 1: Start the driving motor 21, which drives the transmission shaft 211 and the shift roller 2 to rotate. The cylindrical cam groove 22 of the shift roller 2 drives the guide slider 221 to slide along the guide rod 222, and drives the salt spreader 3 to move back and forth in the bath salt cover 1 through the connecting rod 223, accurately controlling the movement trajectory of the salt spreader and improving the stability of the device;

[0058] 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 latex. The stirring shaft 4 rotates to deform the torsion spring 41. After the top block 431 is disengaged, the torsion spring 41 drives the stirring shaft 4 to rotate in the opposite direction, thereby enhancing the stirring effect without the need for additional power.

[0059] Step 3: During the movement of the salt spreading hood 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 hood 3 is close to the discharge port of the temporary storage bucket 12, and salt enters the salt spreading hood 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 hood 3, realizing the precise switching between feeding and salt spreading;

[0060] Step 4: When the salt spreading cover 3 slides in the lifting groove 321, the positioning rack 33 engages 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 guide protrusion 342, it is dispersed to the surrounding area, expanding the salt spreading range and ensuring uniform salt spreading.

[0061] Step 5: The salt spreading hood 3 returns to its initial position after completing the salt spreading cycle, and the blocking block 13 is squeezed to separate it from the connecting pipe 123. The salt spreading hood 3 moves to the bottom of the connecting pipe 123. The guide protrusion 342 is pressed to drive the reset rod 343 to compress the reset spring 346. The slide plate 132 of the blocking block 13 compresses the positioning spring 136 to achieve quantitative filling of the salt spreading hood 3.

[0062] The automatic salt adding device of the intelligent dipping production line for knitted gloves of the present invention is intended to accurately add salt to the latex in the bath salt cover 1. The specific implementation principle is as follows:

[0063] When adding salt to the latex in the bath salt cover 1, the operator first activates the transmission assembly, which drives the drive motor 21 to rotate the transmission shaft 211. The rotation of the transmission shaft 211 causes the shift roller 2 to rotate synchronously, and the cylindrical cam groove 22 on the surface of the shift roller 2 changes synchronously. The specific shape drives the guide slider 221 to slide along the guide rod 222, and the connecting rod 223 drives the salt spreading cover 3 to reciprocate. This transmission method using the cylindrical cam groove and the guide 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.

[0064] During the movement of the salt-spreading cover 3, the top block 431 installed on the side wall of the transmission shaft 211 rotates synchronously, and the top block 431 contacts and pushes the rocker arm 43 on the stirring shaft 4, prompting the stirring shaft 4 to rotate, and 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. When the top block 431 disengages from the rocker arm 43, the torsion spring 41 drives the stirring shaft 4 to rotate in the opposite direction, realizing the reciprocating rotation of the stirring shaft 4 and enhancing the stirring effect. With the help of the transmission shaft linkage stirring assembly, 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 and provides a guarantee for the subsequent smooth salting of the butadiene latex.

[0065] As the salt hood 3 moves, the slide bar 314 slides in the lifting groove 321 and the guide groove 322. When the slide bar 314 slides in the guide groove 322, the salt hood 3 is now in contact with the connecting pipe 123 at the bottom of the temporary storage bucket 12, and the salt in the temporary storage bucket 12 enters the salt hood 3 through the transmission pipe 122 and the connecting pipe 123. As the salt hood 3 continues to move, the slide bar 314 enters the lifting groove 321. The inclined structure of the lifting groove 321 causes the slide bar 314 to drive the push rod 311 upward, and the push rod 311 pushes the top plate 31 to move upward, compressing the compression spring 313. The compression spring 313 facilitates the subsequent reset operation. The salt in the salt hood 3 begins to move toward the upper surface of the salt hood 3 due to the push of the top plate 31, and eventually comes out of the through hole 341. This design, with the help of the cooperation of the jacking groove and the guide groove, cleverly converts the horizontal movement of the salt spreading hood 3 into the lifting movement of the top plate 31, realizes the precise switching of feeding and discharging during the salt spreading process, and ensures the continuity and efficiency of the salt spreading action.

[0066] During this process (as the salt spreading hood 3 slides within the lifting slot 321), the positioning rack 33 and the positioning gear 331 mesh with each other. The rotation of the positioning gear 331 drives the rotation of the synchronizing shaft 332, which in turn drives the lever 333 to rotate. As the lever 333 rotates, it contacts the salt accumulated within the salt spreading hood 3 and, due to its rotational motion, drives the salt outward in a rotational motion. When the rotating salt reaches the arc-shaped guide protrusions 342 on the periphery of the salt spreading hood 3, the arc-shaped guide protrusions 342, with their unique curvature, guide the salt. Under the guidance of the guide protrusions 342, the salt rotates and disperses along a specific arc, significantly increasing the salt spreading range, ensuring that the salt spreading process covers a wider area and improving the efficiency and uniformity of the automatic salt adding device during salting operations. The meshing of the positioning rack 33 and the positioning gear 331 ensures precise synchronization between the rotation of the lever 333 and the movement of the salt spreading hood 3, enhancing the system's synergy. The cooperation between the lever 333 and the arc-shaped guide protrusion 342 breaks through the limitations of traditional salt spreading methods, significantly increases the salt spreading area, makes the salt more evenly distributed in the working area, and meets the requirements for salt spreading effects in different scenarios.

[0067] When the salt hood 3 completes a complete salt spreading cycle and returns to its initial position, the salt hood 3 squeezes the blocking block 13. After being squeezed, the blocking block 13 slowly separates from the connecting pipe 123, and the salt hood 3 can move to the bottom of the connecting pipe 123. There is no gap between the blocking block 13 and the side wall of the salt hood 3, so that salt will not leak. In addition, when the salt hood 3 moves, the chamfered guide protrusion 342 on the salt hood 3 is squeezed and slides downward. The guide protrusion 342 drives the reset rod 343 at the bottom of the guide plate 34 to move with the guide plate 34. The bottom of the reset rod 343 moves in the reset cover 344, causing the pressure plate 345 to compress the reset spring 346. The reset spring 346 facilitates the subsequent reset. With continuous movement, the salt hood 3 eventually slides to the bottom of the connecting pipe 123. When the blocking block 13 slides, the slide plate 132 on the side wall of the blocking block 13 moves along the positioning rod 134 and compresses the positioning spring 136 on the surface of the positioning plate 135, which facilitates subsequent reset.
