Description

Technical Field

[0001] This application relates to the technical field of bath salt production equipment, and particularly to a bath salt mixer and a mixing method. Background Art

[0002] Bath salt, also known as bathing salt, is a solid particulate composed of a combination of various herbs, ground salt, minerals, spices, and plant essential oils. It is rich in various trace elements such as iron, calcium, selenium, and magnesium required by the human body and can be used for bathing, foot bathing, or showering, which can play roles such as cleaning, moisturizing, and relieving fatigue. Long-term use of bath salt can eliminate melanin on the skin, making the skin gradually return to fair, smooth, and elastic, and also has a positive effect on removing facial acne, acne, and freckles. In the production of bath salt, various components need to be stirred and mixed, and a mixer is required during the stirring and mixing process.

[0003] In the prior art, the stirring device generally includes a stirring barrel placed on the ground and a stirring paddle arranged in the stirring barrel for stirring raw materials. The stirring paddle is generally driven to rotate by a motor. However, the bath salt after being stirred evenly contains a certain amount of water and viscous substances such as plant essential oils. Due to the low content of water and plant essential oils, the fluidity of the bath salt after stirring is poor and the viscosity is strong.

[0004] Based on this, it is usually necessary to scrape the bath salt out of the container with a scraper. Currently, the common stirring barrel of the stirring device is generally vertically placed with the opening facing upward, which requires the staff to reach into the stirring barrel to scrape the bath salt. At the same time, the stirring paddle is located in the stirring barrel, further compressing the operating space in the barrel and greatly increasing the difficulty for the staff to scrape out the bath salt. Therefore, it needs to be improved. Summary of the Invention

[0005] In order to facilitate scraping the stirred bath salt out of the container, this application provides a bath salt mixer.

[0006] In a first aspect, a bath salt mixer provided by this application adopts the following technical solution: A bath salt mixer includes a base, a support frame, a mixing tank, a rotating assembly, a lifting assembly, and a stirring assembly. The support frame is arranged on the base. The mixing tank is rotatably connected to the support frame, the rotating shaft of the mixing tank is horizontally arranged, and there is a gap between the bottom of the mixing tank and the support plane of the base. The rotating assembly is connected to the mixing tank and is used to control the rotation of the mixing tank. The lifting assembly is arranged on the base, and the stirring assembly is arranged on the lifting assembly in a lifting manner and is used to stir the raw materials in the mixing tank.

[0007] By adopting the above technical solution, when producing bath salts, the staff first add the raw materials into the mixing tank, then operate the lifting assembly to control the mixing assembly to extend into the mixing tank, and then operate the mixing assembly to mix the raw materials.

[0008] After the mixing is completed, use the lifting assembly to control the mixing assembly to move away from the mixing tank, so that the mixing assembly disengages from the mixing tank; then operate the rotating assembly to control the mixing tank to rotate, so that the mixing tank is inclined, so that the staff can take out the bath salts. During the taking-out process, since there is no mixing assembly in the mixing tank, the staff can have a larger scraping operation space, facilitating the scraping of the mixed bath salts from the container.

[0009] Preferably, the lifting assembly includes a lifting cylinder and a lifting frame. The lifting cylinder is fixed on the base, the lifting frame is connected to the piston rod of the lifting cylinder, and the mixing assembly is arranged on the lifting frame.

[0010] By adopting the above technical solution, the lifting cylinder can control the lifting frame to move up and down, thereby driving the entire mixing assembly to move up and down.

[0011] Preferably, the mixing assembly includes a mixing motor and mixing paddles. The mixing motor is arranged on the lifting frame, the mixing paddles are connected to the drive shaft of the mixing motor, and the rotation axis of the mixing paddles is parallel to the moving direction of the lifting frame.

[0012] By adopting the above technical solution, the mixing motor can control the mixing paddles to rotate, so that the mixing paddles continuously stir the raw materials in the mixing tank. After the mixing paddles rotate, the raw materials can be evenly mixed to realize the production of bath salts.

[0013] Preferably, it further includes a cover plate. The cover plate is arranged on the mixing paddles. The mixing paddles penetrate through the cover plate and are connected to the cover plate through bearings. The cover plate is located directly above the mixing tank and is used to cover the opening of the mixing tank.

[0014] By adopting the above technical solution, when the lifting assembly controls the mixing paddles to gradually approach the mixing tank, the cover plate will also follow and approach the mixing tank. When the mixing paddles are inside the mixing tank, the cover plate just engages with the opening of the mixing tank, realizing the blocking of the raw materials, avoiding the situation of raw material splashing during the mixing process; at the same time, it also avoids the possibility of foreign impurities entering the mixing tank, improving the hygiene. The existence of the bearings can realize the relative rotation of the mixing paddles and the cover plate, that is, when the mixing paddles rotate, the cover plate will not rotate.

[0015] Preferably, the rotating assembly includes a rotating motor and a connecting rod. The driving shaft of the rotating motor is connected to the mixing tank. One end of the connecting rod is connected to the mixing tank, and the other end is rotatably connected to the support frame. The driving shaft of the rotating motor and the connecting rod are on the same straight line, and the driving shaft of the rotating motor has a self-locking function.

[0016] By adopting the above technical solution, the rotating motor can drive the entire mixing tank to rotate, causing the mixing tank to tilt at a certain angle, which is convenient for the bath salt to be discharged. The self-locking function of the driving shaft can prevent the output shaft from continuing to rotate when the motor stops running, thus avoiding the rotation of the mixing tank. This function can be achieved by using existing technical means such as mechanical self-locking structures, electromagnetic self-locking structures, or hydraulic self-locking structures.

[0017] Preferably, it further includes a support block. The support block is arranged on the base in a lifting manner and is located directly below the mixing tank. The support block is used to support the mixing tank.

[0018] By adopting the above technical solution, during the production of bath salt, due to the gap between the mixing tank and the base, the weight of the entire mixing tank is relatively large, and there is a situation where the mixing tank is not stable enough relying only on the support of the rotating assembly. By adding a support block, the support block can play a supporting role for the mixing tank, thereby improving the stability of the mixing tank during the mixing process. After the mixing is completed, control the support block to move away from the mixing tank to facilitate the rotation of the mixing tank.

[0019] Preferably, it further includes a linkage assembly. The linkage assembly is used to connect the lifting frame and the support block. The linkage assembly includes a transmission rack, a transmission gear, a synchronous belt, and a lifting cam. The transmission rack is arranged vertically and is connected to the lifting frame. The transmission gear is rotatably connected to the base and meshes with the transmission rack. The transmission rack is used to control the rotation of the transmission gear; The lifting cam is rotatable on the base and is located below the support block. The lifting cam is used to lift the support block. The lifting cam is connected to the transmission gear through the synchronous belt; when the lifting frame moves in the direction close to the base, the transmission rack drives the transmission gear to rotate, and the lifting cam follows the transmission gear to rotate through the synchronous belt. The long axis of the lifting cam lifts the support block, and the support block moves in the direction close to the mixing tank; When the support block abuts against the bottom of the mixing tank, the cover plate is snap-fitted to the opening of the mixing tank.

[0020] By adopting the above technical solution, after the raw materials are placed in the mixing tank, the lifting cylinder controls the lifting frame to move in the direction close to the mixing tank, and the transmission rack moves vertically downward synchronously, driving the transmission gear to rotate. Under the transmission action of the synchronous belt, the transmission gear can drive the lifting cam to rotate, and at this time the long axis of the lifting cam can lift the support block, so that the support block gradually approaches the mixing tank.

[0021] That is to say, while the stirring assembly gradually extends into the stirring tank, the support block gradually approaches the bottom of the stirring tank. When the support block abuts against the bottom of the stirring tank, the cover plate is just connected to the opening of the stirring tank, and then the lifting frame stops moving. The lifting cylinder has a self-locking function. After the cylinder stops moving, the piston rod will not extend or retract, and can maintain the current position without falling back or slipping.

[0022] Preferably, an anti-slip layer is provided on the supporting surface of the supporting block.

[0023] By adopting the above technical solution, the friction coefficient of the anti-slip layer is relatively large, which can increase the contact static friction between the support block and the stirring tank.

[0024] In a second aspect, the present application also provides a stirring method for producing bath salts, comprising the following steps: S1, the raw materials are first added into the stirring tank, then the lifting component is operated to control the stirring component to extend into the stirring tank, and then the stirring component is operated to stir the raw materials; S2. After the stirring is completed, the lifting component is used to control the stirring component to move away from the stirring tank; and then the rotating component is operated to control the stirring tank to rotate so that the bath salt can be taken out.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: (1) By setting a rotating component, a lifting component and a stirring component, when the raw materials are stirred, the lifting component is used to control the stirring component to move away from the stirring tank, so that the stirring component is separated from the stirring tank; then the rotating component is operated to control the stirring tank to rotate, so that the stirring tank is tilted so that the staff can take out the bath salt. During the removal process, since there is no stirring component in the stirring tank, the staff can have a larger scraping operation space, so that the stirred bath salt can be scraped out of the container conveniently.

[0026] (2) By setting a cover plate, the cover plate can be snapped into the opening of the mixing tank to block the raw materials and avoid splashing of the raw materials during the mixing process; at the same time, it also prevents the possibility of external impurities entering the mixing tank, thereby improving production hygiene.

[0027] (3) By setting the support block and the linkage assembly, when the cover plate gradually covers the opening of the mixing tank, the linkage assembly can drive the support block to gradually approach the bottom of the mixing tank to achieve support. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will describe in detail some embodiments of the present application with reference to the drawings. Without conflict, those skilled in the art can combine and combine the different embodiments or examples represented in the present application and the features of different embodiments or examples.

[0035] The embodiments of the present application disclose a bath salt mixer. Referring to Figure 1 and Figure 2 , the bath salt mixer includes a base 1, a support frame 2, a mixing tank 3, a rotating assembly 4, a lifting assembly 5, and a mixing assembly 6. The base 1 serves as a carrier and is fixedly installed on the ground. The support frame 2 is fixed on the base 1, the mixing tank 3 is rotatably connected to the support frame 2, the rotating shaft of the mixing tank 3 is in the horizontal direction, and there is a gap between the bottom of the mixing tank 3 and the support surface of the base 1. The rotating assembly 4 is installed on the support frame 2 and is connected to the mixing tank 3, and the rotating assembly 4 is used to control the rotation of the mixing tank 3. The lifting assembly 5 is installed on the base 1, the mixing assembly 6 is arranged to be lifted and is connected to the lifting assembly 5, and the mixing assembly 6 is used to stir the raw materials in the mixing tank 3.

[0036] During the bath salt production process, the staff first adds the raw materials into the mixing tank 3. Then, the lifting assembly 5 is started, and the mixing assembly 6 is controlled to descend and penetrate into the mixing tank 3. Immediately afterwards, the mixing assembly 6 is turned on to fully stir the raw materials in the tank. After the stirring process is completed, the lifting assembly 5 is used again to drive the mixing assembly 6 to rise until it completely disengages from the mixing tank 3. Subsequently, the rotating assembly 4 is started to rotate the mixing tank 3 and tilt it to an appropriate angle to facilitate the staff to take out the bath salt. During this process, since there is no mixing assembly 6 in the mixing tank 3 to obstruct, the staff has a more ample operating space for scraping operations, so that the stirred bath salt can be conveniently scraped out of the tank.

[0037] Specifically, the lifting assembly 5 includes a lifting cylinder 51 and a lifting frame 52. The lifting cylinder 51 is fixed on the base 1 and is located on one side of the mixing tank 3. The lifting frame 52 is located above the base 1 and is connected to the piston rod of the lifting cylinder 51. The mixing assembly 6 is installed on the lifting frame 52. The lifting cylinder 51 can control the up and down movement of the lifting frame 52, thereby driving the entire mixing assembly 6 to move up and down. In this embodiment, two lifting cylinders 51 are provided. The two lifting cylinders 51 are located on both sides of the mixing tank 3. The lifting frame 52 is connected to the two lifting cylinders 51. The two lifting cylinders 51 jointly apply force to the lifting frame 52 to improve the stability of the lifting frame 52 during movement.

[0038] Combined with Figure 3 and Figure 4 , the mixing assembly 6 includes a mixing motor 61 and a mixing paddle 62. The mixing motor 61 is installed on the lifting frame 52. The mixing paddle 62 is connected to the drive shaft of the mixing motor 61. The rotation axis of the mixing paddle 62 is parallel to the moving direction of the lifting frame 52. The mixing paddle 62 is used for mixing raw materials. The mixing motor 61 can control the rotation of the mixing paddle 62, so that the mixing paddle 62 continuously stirs the raw materials in the mixing tank 3. After the mixing paddle 62 rotates, it can mix various raw materials evenly to realize the production of bath salts.

[0039] Among them, a cover plate 7 is also installed on the mixing paddle 62. The mixing paddle 62 penetrates through the cover plate 7. The cover plate 7 and the mixing paddle 62 are connected by a bearing. The cover plate 7 is located directly above the mixing tank 3 and is used to cover the opening of the mixing tank 3. When the lifting assembly 5 drives the mixing paddle 62 to gradually approach the mixing tank 3, the cover plate 7 also approaches the mixing tank 3 synchronously. When the mixing paddle 62 completely enters the interior of the mixing tank 3, the cover plate 7 just engages with the opening part of the mixing tank 3, thereby achieving an effective barrier to the raw materials. This design can prevent the raw materials from splashing during the mixing process and avoid foreign impurities from entering the mixing tank 3, greatly improving the hygiene level of the production process. In addition, the setting of the bearing enables the mixing paddle 62 and the cover plate 7 to rotate relative to each other, that is, when the mixing paddle 62 rotates, the cover plate 7 remains stationary and does not rotate synchronously.

[0040] The rotating assembly 4 includes a rotating motor 41 and a connecting rod 42. The drive shaft of the rotating motor 41 is fixedly connected to the side wall of the mixing tank 3. One end of the connecting rod 42 is fixedly connected to the mixing tank 3, and the other end is rotatably connected to the support frame 2. The drive shaft of the rotating motor 41 and the connecting rod 42 are on the same straight line. The rotating motor 41 can drive the entire mixing tank 3 to rotate, causing the mixing tank 3 to tilt at a certain angle, facilitating the feeding of bath salts. Among them, the drive shaft of the rotating motor 41 has a self-locking function. The self-locking function of the drive shaft is to prevent the output shaft from continuing to rotate when the motor stops running, thereby avoiding the rotation of the mixing tank 3. This function can be achieved by using existing technical means such as mechanical self-locking structures, electromagnetic self-locking structures, or hydraulic self-locking structures. These structures belong to the prior art and can be directly applied to this application without further elaboration.

[0041] In some embodiments, a support block 8 is also arranged on the base 1 in a lifting manner. The structure for the support block 8 to lift can adopt the cooperation of a sliding block and a sliding groove. The support block 8 is located directly below the mixing tank 3 and is used to support the mixing tank 3. A linkage assembly 9 is also installed on the base 1, and the linkage assembly 9 is used to connect the lifting frame 52 and the support block 8. The linkage assembly 9 includes a transmission rack 91, a transmission gear 92, a synchronous belt 93, and a jacking cam 94. The transmission rack 91 is arranged vertically and is fixedly connected to the lifting frame 52. The transmission gear 92 is rotatably connected to the base 1 and meshes with the transmission rack 91. The transmission rack 91 is used to control the rotation of the transmission gear 92.

[0042] The jacking cam 94 is rotatably arranged on the base 1 and is located directly below the support block 8. The jacking cam 94 is used to jack up the support block 8; the jacking cam 94 is connected to the transmission gear 92 through the synchronous belt 93, and the transmission gear 92 is used to drive the jacking cam 94 to rotate. When the lifting frame 52 moves downward in the direction close to the base 1, the transmission rack 91 drives the transmission gear 92 to rotate, and the jacking cam 94 follows the transmission gear 92 to rotate through the synchronous belt 93. The long axis of the jacking cam 94 jacks up the support block 8, causing the support block 8 to move upward in the direction close to the mixing tank 3. When the support block 8 abuts against the bottom of the mixing tank 3, the cover plate 7 just engages with the opening of the mixing tank 3, and then the lifting frame 52 stops moving. The lifting cylinder 51 has a self-locking function. After the cylinder stops moving, the piston rod will not expand or contract and has the ability to maintain the current position without falling back or slipping. The structures of the cylinder self-locking function mainly include mechanical lock pin type self-locking structures, wedge block type locking mechanisms, and spherical inclined groove type self-locking structures. These structures belong to the prior art and can be directly used in this application. Among them, an anti-slip layer is provided on the support surface of the support block 8, and the anti-slip layer is used to increase the contact friction between the support block 8 and the mixing tank 3.

[0043] The implementation principle of a bath salt mixer in an embodiment of this application is as follows: When producing bath salt, the staff first add the raw materials into the mixing tank 3, and then use the lifting cylinder 51 to control the lifting frame 52 to move downward, so that the mixing assembly 6 extends into the mixing tank 3. The cover plate 7 will also gradually approach the mixing tank 3 and block the opening of the mixing tank 3. At the same time, under the action of the linkage assembly 9, the downward movement of the lifting frame 52 will drive the lifting cam 94 to rotate, and the lifting cam 94 will lift the support block 8, thus supporting the mixing tank 3. When the support block 8 abuts against the bottom of the mixing tank 3, the cover plate 7 just engages with the opening of the mixing tank 3, and then the mixing assembly 6 is operated to stir the raw materials.

[0044] After the stirring is completed, use the lifting assembly 5 to control the mixing assembly 6 to move away from the mixing tank 3, so that the mixing assembly 6 disengages from the mixing tank 3. At this time, the lifting cam 94 rotates in reverse, driving the support block 8 away from the mixing tank 3, leaving a gap between the mixing tank 3 and the base 1; Then operate the rotating assembly 4 to control the mixing tank 3 to rotate, so that the mixing tank 3 is inclined, so that the staff can take out the bath salt. During the taking-out process, since there is no mixing assembly 6 in the mixing tank 3, the staff can have a larger space for scraping operation, and it is convenient to scrape out the stirred bath salt from the container.

[0045] Based on the above embodiments, an embodiment of this application also provides a mixing method for producing bath salt. This method uses the bath salt mixer with all the above structures, and specifically includes the following steps: S1. First, add each raw material into the mixing tank 3, and then start the lifting cylinder 51 to control the lifting frame 52 to move downward, so that the mixing assembly 6 extends into the mixing tank 3; the cover plate 7 follows the mixing paddle 62 and approaches the mixing tank 3 synchronously; At the same time, the downward movement of the lifting frame 52 will drive the transmission gear 92 to rotate clockwise. Under the connection of the synchronous belt 93, the lifting cam 94 rotates clockwise synchronously. The long shaft of the lifting cam 94 lifts the support block 8, so that the support block 8 moves upward in the direction close to the mixing tank 3; When the support block 8 abuts against the bottom of the mixing tank 3, the cover plate 7 just engages with the opening of the mixing tank 3, and then start the mixing motor 61 to control the mixing paddle 62 to stir the raw materials; S2. After the stirring is completed, control the lifting frame 52 to move vertically upward, so that the mixing assembly 6 and the cover plate 7 gradually move away from the mixing tank 3; at the same time, the lifting cam 94 rotates in reverse, and the short shaft of the lifting cam 94 contacts the support block 8. The support block 8 gradually moves away from the mixing tank 3 under its own gravity, leaving a gap between the bottom of the mixing tank 3 and the base 1; S3. Finally, operate the rotating motor 41 to control the mixing tank 3 to rotate, so that the mixing tank 3 is inclined, so that the staff can take out the bath salt.

[0046] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
