Description

Technical Field

[0001] This invention relates to the field of hand mask processing equipment technology, and in particular to a hand mask liquid dispensing device and its liquid dispensing rod. Background Technology

[0002] This hand mask contains a variety of natural plant extracts and abundant bioactive cell molecules. It gently dissolves dead skin cells, deeply moisturizes, and nourishes nails from the root, improving the hands' defense and self-repair capabilities. Combined with natural vitamins, it makes calluses and rough skin on the hands soft, smooth, delicate, white, and elastic.

[0003] During the production of hand masks, a hand mask paste is injected between two membrane fabrics, which are then heat-fused and cut into finished hand masks. Traditional hand mask paste injection mechanisms mostly rely on pumps and valves to inject the paste. This requires controlling the start and stop of multiple electronic components, making injection malfunctions common and difficult to achieve quantitative and uniform injection. Furthermore, traditional hand mask injection rods are mostly tubular, spraying the paste only onto the palm, failing to achieve uniform injection on the inner side of the mask, impacting the customer experience. Additionally, because the paste is paste-like, some paste remains on the injection rod during injection. This residue can fall onto other parts of the membrane fabric. If the paste falls onto the heat-fusion interface, it can affect the heat fusion, leading to poor heat fusion stability and a poor seal. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of poor quantitative and uniform spraying of hand mask ointment, excessive liquid injection components leading to liquid injection failure, poor uniformity of liquid addition to the mask cloth, and poor stability of the heat fusion of the two mask cloths. Therefore, a hand mask liquid addition device and its liquid addition rod are proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hand mask liquid dispensing device includes a base and a liquid injection tank fixed to the top of the base via a connecting column. A receiving sleeve is fixedly connected to the inner side of the liquid injection tank. The receiving sleeve is connected to a conformal dispensing rod via a liquid inlet pipe penetrating the liquid injection tank. A one-way valve is installed at one end of the liquid inlet pipe near the receiving sleeve. The inner side of the liquid injection tank has a lifting and conveying mechanism for conveying the hand mask ointment to the top of the lifting sleeve. Above the receiving sleeve is a plunger block for squeezing and conveying the hand mask ointment to the inner side of the conformal dispensing rod. A one-way air inlet valve is installed on the plunger block. The plunger block has a reciprocating drive mechanism that operates synchronously with the lifting and conveying mechanism. The reciprocating drive mechanism can drive the plunger block to move up and down reciprocally.

[0007] As a further description of the above technical solution:

[0008] The lifting and conveying mechanism includes a lifting sleeve fixed to the inside of the injection tank by multiple support columns. There is a gap between the bottom of the lifting sleeve and the bottom of the inside of the injection tank. A conveying screw is rotatably connected to the inside of the lifting sleeve. A first drive motor for driving the conveying screw to rotate is installed at the bottom of the injection tank. The top of the outer side of the lifting sleeve near the receiving sleeve has an inclined discharge trough.

[0009] As a further description of the above technical solution:

[0010] The reciprocating drive mechanism includes a cam for driving the plunger block to move downward. A support plate is installed on the top of the lifting sleeve. A horizontally distributed mounting shaft is rotatably connected to the support plate. A large helical gear and a cam are fixedly connected to both ends of the mounting shaft, respectively. A connecting shaft penetrating the lifting sleeve is coaxially fixedly connected to the top of the feeding screw. A small helical gear that meshes with the large helical gear is coaxially fixedly connected to the outside of the connecting shaft.

[0011] As a further description of the above technical solution:

[0012] The reciprocating drive mechanism also includes multiple transmission bends. The receiving sleeve is fixedly connected to an installation ring, and the bottom of the installation ring is fixedly connected to the bottom of the inner side of the injection tank through multiple support rods. The first ends of the multiple transmission bends slide through the installation ring, and the second ends of the multiple transmission bends are fixedly connected to the plunger block. The outside of the multiple transmission bends is fitted with a reset spring for driving the multiple transmission bends to reset upward.

[0013] As a further description of the above technical solution:

[0014] A liquid dispensing device for hand membranes includes a dispensing rod, comprising a mounting base and a palm-shaped dispensing rod. The palm and fingers of the dispensing rod are provided with multiple injection nozzles. The mounting base is fixed to a base by a mounting bracket. The dispensing rod is mounted on the mounting base. The mounting base has a scraping and receiving assembly for scraping material from the bottom of the injection nozzles.

[0015] As a further description of the above technical solution:

[0016] The top of the mounting base has a mounting groove for mounting a contoured liquid injection rod, and the interior of the mounting base near the lower part of the mounting groove has a through hole for use with multiple liquid injection nozzles, the bottom of the multiple liquid injection nozzles being flush with the bottom of the mounting base.

[0017] As a further description of the above technical solution:

[0018] The scraping and receiving assembly includes a scraper that slides on the bottom of the mounting base. A detachable sliding receiving groove is fixedly connected to the bottom of the scraper. Positioning blocks are fixedly connected to both sides of the front wall of the base. A transmission frame is fixedly connected to the front wall of the sliding receiving groove. Two sets of positioning rods that pass through the two positioning blocks are fixedly connected to both sides of the transmission frame. The transmission frame has a transmission groove inside, and a transmission column is provided on the inner side of the transmission groove. A second drive motor is installed on the front wall of the mounting base. A transmission rod is fixedly connected to the side wall of the output shaft of the second drive motor, and the transmission rod is fixedly connected to the transmission column. The second drive motor drives the transmission column to slide in the transmission groove, which can drive the transmission frame to slide left and right.

[0019] As a further description of the above technical solution:

[0020] The mounting base has detachable material receiving grooves fixedly connected to both sides of its bottom.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. In this invention, the lifting and conveying mechanism continuously transports the hand mask ointment from the bottom of the injection tank towards the receiving sleeve, thereby filling the receiving sleeve when it separates from the plunger block. This ensures that the receiving sleeve receives the same amount of ointment each time, thus guaranteeing that the amount of hand mask ointment sprayed by the contouring injection rod is the same each time. Furthermore, the lifting and conveying mechanism mixes the hand mask ointment inside the injection tank while conveying the ointment, preventing sedimentation. The quantitative delivery and mixing of the hand mask ointment through mechanical structures ensures the uniformity and stability of the quantitative delivery of the hand mask ointment. Moreover, the synchronous operation of the lifting and conveying mechanism and the reciprocating drive mechanism ensures the continuity and matching of receiving and discharging of the receiving sleeve. It eliminates the need for multiple electronic components to control the quantitative injection and discharge of the hand mask ointment, preventing injection failures caused by control errors between injection and discharge. This solves the problems of poor quantitative and uniform spraying of hand mask ointment and injection failures caused by too many electronic components.

[0023] 2. In this invention, the conformal liquid dispensing rod has a palm-shaped structure, and the bottom of the conformal liquid dispensing rod has multiple liquid injection nozzles at the palm and finger positions. This allows the hand-applied ointment sprayed by the conformal liquid dispensing rod to be evenly sprayed onto the top of the membrane fabric. Furthermore, the scraping and receiving component can scrape off any residual hand-applied ointment from the liquid injection nozzles, preventing the residual ointment from falling down to other parts of the membrane fabric and causing malfunctions in the heat-fusion connection between the two membrane fabrics. This solves the problems of poor uniformity of liquid dispensing to the membrane fabric and poor stability of the heat fusion between the two membrane fabrics. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] For examples, please refer to Figure 1-8 This invention provides a technical solution: a hand mask liquid dispensing device, including a base 1 and a liquid injection tank 3 fixed to the top of the base 1 via a connecting column 101. A receiving sleeve 18 is fixedly connected to the inner side of the liquid injection tank 3. The receiving sleeve 18 is connected to a contoured dispensing rod 4 via a liquid inlet pipe 19 penetrating the liquid injection tank 3. A one-way valve 20 is installed at one end of the liquid inlet pipe 19 near the receiving sleeve 18. The inner side of the liquid injection tank 3 has a lifting and conveying mechanism for conveying the hand mask ointment to the top of a lifting sleeve 5. Above the receiving sleeve 18 is a plunger block 15 for squeezing and conveying the hand mask ointment to the inner side of the contoured dispensing rod 4. A one-way air inlet valve 1501 is installed on the plunger block 15. The plunger block 15 has a reciprocating drive mechanism that operates synchronously with the lifting and conveying mechanism. The reciprocating drive mechanism can drive the plunger block 15 to move up and down reciprocally. Through the lifting and conveying mechanism, the hand mask ointment at the bottom of the inner side of the injection tank 3 is continuously conveyed to the receiving sleeve 18, so that the receiving sleeve 18 is filled when it separates from the plunger block 15. In addition, the lifting and conveying mechanism mixes the hand mask ointment inside the injection tank 3 while conveying the material to prevent the hand mask ointment from settling. Furthermore, the reciprocating drive mechanism can drive the plunger block... As the plunger block 15 moves up and down repeatedly, when it moves downwards to the inside of the receiving sleeve 18, it injects the hand mask ointment from inside the receiving sleeve 18 into the inside of the conformal filling rod 4. The conformal filling rod 4 then sprays the hand mask ointment onto the membrane cloth. The one-way valve 20 prevents the hand mask ointment in the inlet pipe 19 from being reabsorbed into the inside of the receiving sleeve 18 when the plunger block 15 moves upwards. The one-way air inlet valve 1501 allows air in the injection tank 3 to flow through the one-way air inlet valve 1501 to the inside of the plunger block 15 and the receiving sleeve 18 when the plunger block 15 moves upwards, thus ensuring proper flow of the ointment. The pressure at both ends of block 15 is the same, which facilitates the upward reset of plunger block 15. This ensures that the receiving sleeve 18 receives the same amount of material each time, thereby ensuring that the amount of hand mask ointment sprayed by the contouring liquid injection rod 4 is the same each time. The quantitative hand mask ointment is delivered only through mechanical structure, which ensures the uniformity and stability of the quantitative delivery of hand mask ointment. Furthermore, the synchronous operation of the conveying mechanism and the reciprocating drive mechanism can ensure the continuity and matching of receiving and discharging of material by the receiving sleeve 18. There is no need for multiple electronic components to control the quantitative injection and discharge of hand mask ointment, which prevents injection failure caused by control errors between injection and discharge.

[0036] Specifically, such as Figure 3As shown, the reciprocating drive mechanism includes a cam 12 for driving the plunger block 15 to move downward. A support plate 10 is mounted on the top of the lifting sleeve 5. A horizontally distributed mounting shaft 11 is rotatably connected to the support plate 10. Large helical gears 13 and the cam 12 are fixedly connected to both ends of the mounting shaft 11, respectively. A connecting shaft 8 that passes through the lifting sleeve 5 is coaxially fixedly connected to the top of the feeding screw 6. Small helical gears 9 that mesh with the large helical gears 13 are coaxially fixedly connected to the outside of the connecting shaft 8. The reciprocating drive mechanism also includes multiple transmission bends 14. A mounting ring 17 is fixedly connected to the receiving sleeve 18, and the mounting... The bottom of the mounting ring 17 is fixedly connected to the bottom inner side of the injection tank 3 via multiple support rods 302. The first ends of multiple transmission bends 14 slide through the mounting ring 17, and the second ends of multiple transmission bends 14 are fixedly connected to the plunger block 15. A return spring 16 is sleeved on the outside of the multiple transmission bends 14 to drive them upwards. The lifting and conveying mechanism includes a lifting sleeve 5 fixed to the inside of the injection tank 3 via multiple support columns 301. There is a gap between the bottom of the lifting sleeve 5 and the bottom inner side of the injection tank 3. A conveying screw 6 is rotatably connected to the inside of the lifting sleeve 5. The bottom of the box 3 is equipped with a first drive motor 7 for driving the feed screw 6 to rotate. The top outer side of the lifting sleeve 5, near the receiving sleeve 18, has an inclined discharge trough 501. The feed screw 6 conveys the hand-mask ointment between the bottom of the lifting sleeve 5 and the injection tank 3 to the top inner side of the lifting sleeve 5, and then through the discharge trough 501 to the inner side of the receiving sleeve 18. The rotation of the feed screw 6 drives the rotation of the connecting shaft 8 and the small helical gear 9. Through the meshing transmission of the small helical gear 9 and the large helical gear 13, the mounting shaft 11 and the cam 12 are driven to rotate. Rotation of 12 drives the plunger block 15 to move downward. As the plunger block 15 continues to rotate, the transmission bend 14 and the plunger block 15 are reset upward under the action of the return spring 16, so that the plunger block 15 can move up and down continuously. The transmission bend 14 is set for the stable up and down sliding of the plunger block 15. The small helical tooth 9 drives the large helical tooth 13. The feeding screw 6 and the small helical tooth 9 rotate multiple times to drive the large helical tooth 13 once, ensuring that the hand film balm output by the feeding screw 6 can fill the inside of the receiving sleeve 18, so that the lifting conveying mechanism and the reciprocating drive mechanism are stably connected.

[0037] Examples, such as Figure 5-7As shown, a liquid dispensing device for hand membranes includes a dispensing rod, a mounting base 2, and a palm-shaped dispensing rod 4. The bottom of the dispensing rod 4, near the palm and fingers, has multiple injection nozzles 401. The mounting base 2 is fixed to the base 1 via a mounting bracket 102. The dispensing rod 4 is mounted on the mounting base 2. The mounting base 2 has a scraping and receiving assembly for scraping material from the bottom of the injection nozzles 401. The dispensing rod 4 has a palm-shaped structure and is a standard part matching the standard hand membrane. The multiple injection nozzles 401 at the bottom of the dispensing rod 4 allow the hand membrane paste sprayed from the dispensing rod 4 to be evenly sprayed onto the membrane fabric. The scraping and receiving assembly removes any residual hand membrane paste from the injection nozzles 401, preventing it from falling onto other parts of the membrane fabric and causing malfunctions in the heat-sealing connection between the two membrane fabrics.

[0038] Specifically, such as Figure 3 and Figure 4 As shown, the top of the mounting base 2 has a mounting groove 201 for mounting the contoured liquid injection rod 4. The interior of the mounting base 2, near the mounting groove 201, has through holes 202 for use with multiple injection nozzles 401. The bottoms of the multiple injection nozzles 401 are flush with the bottom of the mounting base 2. The scraping and receiving assembly includes a scraper 29 that slides on the bottom of the mounting base 2. A detachable sliding receiving groove 27 is fixedly connected to the bottom of the scraper 29. Positioning blocks 22 are fixedly connected to both sides of the front wall of the base 1. A transmission frame 28 is fixedly connected to the front wall of the sliding receiving groove 27. Two sets of positioning rods 21, penetrating the two positioning blocks 22, are fixedly connected to both sides of the transmission frame 28. The transmission frame 28 has a transmission groove 2801 inside, and a transmission column 25 is provided on the inner side of the transmission groove 2801. A second drive motor 23 is mounted on the front wall of the mounting base 2. A transmission rod 24 is fixedly connected to the side wall of the output shaft of the second drive motor 23. The transmission rod 24 is fixedly connected to the transmission column 25. The second drive motor 23 drives the transmission column 25 to slide in the transmission groove 2801, which can drive the transmission frame 28 to slide left and right. The bottom sides of the mounting base 2 are fixedly connected to detachable fixed receiving grooves 26. The positioning block 22 positions the positioning rod 21 and the transmission frame 28 to slide left and right. The second drive motor 23 drives the transmission rod 24 and the transmission column 25 to rotate, so that the transmission column 25 slides in the transmission groove 2801, thereby driving the transmission frame 28 to slide left and right. The transmission frame 28 drives the sliding receiving groove 27 and the scraper 29 to slide left and right. The scraper 29 scrapes the residual hand mask ointment on the injection nozzle 401 to the inside of the sliding receiving groove 27. By setting the fixed receiving groove 26, the hand mask ointment remaining on the mounting base 2 when the scraper 29 is scraped to the limit position can be collected to prevent the hand mask ointment from falling down.
