Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic production equipment, and in particular relates to a manual filling machine which can be used for adjusting the volume of liquid cosmetics. Background Art

[0002] At present, there are more and more categories of cosmetics, and the classifications are becoming more and more detailed. Cosmetics are in liquid or paste form. After the production of cosmetics is completed, the cosmetic containers will be filled in sequence. Although the equipment used for filling is becoming more and more abundant nowadays, this equipment is only suitable for large-scale production, so as to give full play to the advantages of filling machines and save a lot of costs. However, when testing samples or small-scale trial production, using large-scale filling machines will not only fail to save costs, but will increase cost investment and accelerate equipment loss, especially to calibrate and adjust quantitative filling, which will increase labor costs. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a manual filling machine that can be used to adjust the volume of liquid cosmetics. The quantitative amount of each filling is adjusted by twisting the nut on the screw. The equipment has a simple structure and only requires the intervention of a cylinder and manual start-up to complete the quantitative filling. It is suitable for small-scale trial production and has low cost.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A manual filling machine for adjusting the volume of liquid cosmetics comprises a material storage tank, a filling assembly and a driving assembly, wherein a material guide cylinder is provided at the lower end of the material storage tank, a material outlet is provided on the side wall of the material guide cylinder, and a detachably connected guide cylinder is provided at the opening of the material outlet; the filling assembly comprises a feed sheet, a receiving sheet and a limit ring embedded in the material guide cylinder, and the limit ring is located below the material outlet; the driving assembly comprises a cylinder, a screw and a nut, the output end of the cylinder is connected to the screw, and the screw passes through the limit ring from bottom to top The nut is screwed on the screw rod and the upper end face of the nut is connected to the bottom of the supporting piece. The lower end of the outer edge of the supporting piece is connected to the upper end face of the limiting ring. The feeding piece extends from the material guide barrel into the storage tank under the drive of the cylinder. The supporting piece is a columnar structure, and a flat surface and an inclined surface are provided on the upper end face of the supporting piece. When the bottom face of the supporting piece is in contact with the limiting ring, the flat surface, the inclined surface and the discharge port form a continuous discharge cavity.

[0006] The filling assembly also includes a limit column, which is vertically arranged in the material guiding barrel, and the lower end face of the limit column is connected to the limit ring. The supporting piece is provided with a limit groove, which is vertically arranged on the outer wall of the supporting piece and located in the middle position of the flat surface, and the limit groove cooperates with the limit column; the feeding piece is provided with a matching hole which passes through from top to bottom, and the matching hole cooperates with the limit column.

[0007] It also includes a support assembly, which includes a fixed seat and a support cover. The fixed seat is arranged on the outer wall of the material guide barrel, and the support cover is detachably connected to the lower end of the fixed seat. The support cover is provided with a through hole for the discharge port to pass through, and the cylinder is arranged on the support cover; the drive assembly also includes a connecting plate, which is horizontally placed in the support cover, and the output end of the cylinder is connected to the screw through the connecting plate.

[0008] The manual filling machine adopting this structure can be used for adjusting the volume of liquid cosmetics. The storage tank is used to hold the liquid cosmetics, which can flow out from the discharge port along the direction guided by the guide cylinder after following the guide cylinder at the lower end of the storage tank. The fixed seat and the support cover are for stabilizing the effect. In order to achieve quantitative adjustment of the volume of each outflow, a filling component is added. The feed sheet on the filling component is connected by the screw of the driving component. The lower end of the screw is connected to the cylinder through a connecting plate, forming a Z-shaped structure. Therefore, when the cylinder is driven, the feed sheet enters / exits the storage tank from the guide cylinder. The cylinder limits the upward movement limit to that the feed sheet is slightly higher than the connection between the storage tank and the guide cylinder, so that the liquid cosmetics in the storage tank can enter the guide cylinder along the gap between the feed sheet and the guide cylinder. When the feed sheet moves down After entering the material guide barrel, since the outer edge of the feed sheet cooperates with the inner wall of the material guide barrel, the liquid cosmetics in the storage tank can be isolated at the upper end of the feed sheet; in order to perform quantitative control, a receiving sheet can be movably connected to the screw, and the receiving sheet of a columnar structure is matched with the screw at the connection point, and the outer wall of the receiving sheet also cooperates with the inner wall of the material guide barrel, so that the liquid cosmetics entering from the upper end can be restricted to the upper end of the receiving sheet, so the space between the feed sheet and the receiving sheet can be adjusted to achieve the effect of quantitative control. In order to limit the distance between the feed sheet and the receiving sheet to achieve the effect of limiting the capacity, a nut is screwed into the screw at the lower end of the receiving sheet, so that the upper end face of the nut abuts against the lower end of the receiving sheet, and the distance between the feed sheet and the receiving sheet can be adjusted by twisting the nut.

[0009] However, during the downward movement of the material receiving piece, if it is lower than the position of the discharge port, the liquid cosmetics on its upper end will move downward along with the downward movement of the material receiving piece, making it impossible for the liquid cosmetics to flow out completely, and the capacity limitation between the feed piece and the material receiving piece will also lose its meaning. Therefore, a limit ring is set at the lower end of the connection between the guide barrel and the discharge port, and the screw and the nut both pass through the middle of the limit ring. The material receiving piece is located at the upper end of the limit ring. Therefore, when the material receiving piece moves downward and is blocked by the limit ring, the flat surface, inclined surface and discharge port at the upper end of the material receiving piece form a continuous discharge cavity, and the screw continues to move downward with the nut, driving the feed piece to continue to press down the liquid cosmetics in the guide barrel and flow out smoothly along the discharge cavity. The liquid cosmetics will not accumulate at the upper end of the material receiving piece, so that quantitative control can be achieved. The downward movement limit of the cylinder is that the feed piece will not be lower than the discharge port. Therefore The liquid cosmetics on the upper end of the feed sheet can be prevented from flowing out from the discharge port. Since the receiving sheet can prevent the liquid cosmetics from penetrating downwards from the gap between it and the guide barrel, the lower end surface of the guide barrel is downwardly open, which can facilitate the nut to pass through the guide barrel as the screw moves downward, and also facilitates the quantitative adjustment of the nut by twisting the up and down position. In order to ensure that the flat surface, inclined surface and discharge port on the receiving sheet can form a continuous discharge cavity, it is necessary to limit the lateral position of the receiving sheet. Therefore, a vertical limit column is arranged in the guide barrel, and the limit column cooperates with the limit groove on the outer wall of the receiving sheet. Therefore, the receiving sheet will move up and down along the direction of the limit column during the up and down movement. At the same time, a matching hole cooperating with the limit column is provided on the feed sheet, so that the feed sheet can still keep the liquid cosmetics on its upper end isolated during the downward movement.

[0010] Therefore, the working process of the manual filling machine is to load the liquid cosmetics into the storage tank and keep it ready for use. The screw is pushed upward by manually starting the cylinder, and the nut on the screw will also lift the receiving piece to move upward until the feed piece extends into the storage tank. The liquid cosmetics follow the gap between the feed piece and the guide barrel and enter between the feed piece and the receiving piece for filling. Because it is liquid cosmetics, the filling speed is fast and there will be no gaps. After the filling is completed, the screw is moved downward, so that the feed piece moves downward and enters the guide barrel, and the receiving piece also moves downward synchronously. The space is the quantitative capacity. During the downward movement, the receiving sheet moves down first and passes through the discharge port, and part of the liquid cosmetics on it will flow out through the discharge port first. The receiving sheet that continues to move down abuts against the limiting ring, and the screw and nut continue to move downward, so that the feed sheet continues to be pressed downward, and the liquid cosmetics at its lower end flows out of the discharge cavity. After the discharge is completed, the screw is moved up again until the nut abuts against the lower end of the receiving sheet again and moves up for refilling. When the nut moves to the lowest end, the nut can be twisted to adjust the distance between the nut and the feed sheet, thereby changing the capacity.

[0011] Furthermore, it also includes a stroke component, which includes a buffer ring and a touch head. The buffer ring is embedded in the material guide barrel and is located between the storage tank and the discharge port. The flat surface is connected to the buffer ring in an abutment manner. The touch head is arranged in the support cover, and the connecting plate is connected to the touch head in an abutment manner.

[0012] Compared with the prior art, the advantages of the utility model are: the screw is driven up and down by the cylinder to realize the process of filling, feeding and discharging, the inclined receiving piece can facilitate the liquid cosmetics on it to be discharged from the discharge port in time, and the nut on the screw is adjusted up and down to change the distance between the receiving piece and the feeding piece, thereby changing the size of the space between them, and finally achieving the effect of quantitative adjustment. By manually starting the cylinder, quantitative filling of liquid cosmetics can be carried out, which can be used in trial production or small batch production. Its power consumption is only that of the cylinder drive, the use cost is low, and the quantitative adjustment is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Description of the working method of this utility model:

[0031] The manual filling machine with this structure can be used for adjusting the volume of liquid cosmetics. The storage tank 1 is used to hold the liquid cosmetics, which can flow out from the discharge port 12 along the direction guided by the guide cylinder 13 after following the guide cylinder 11 at the lower end of the storage tank 1. The fixing seat 41 and the support cover 42 are for stabilizing the flow. In order to achieve quantitative adjustment of the volume of each outflow, a filling component 2 is added. The feed sheet 21 on the filling component 2 is connected by the screw 32 of the driving component 3. The lower end of the screw 32 is connected to the cylinder 31 through a connecting plate 34, forming a Z-shaped structure. Therefore, when the cylinder 31 is driven, the feed sheet 21 enters / exits the storage tank 1 from the guide cylinder 11. The cylinder 31 limits the upward movement limit in that the feed sheet 21 is slightly higher than the connection between the storage tank 1 and the guide cylinder 11, so that the liquid cosmetics in the storage tank 1 can enter the guide cylinder 11 along the gap between the feed sheet 21 and the guide cylinder 11. When the feed sheet 21 moves down into After entering the material guide barrel 11, since the outer edge of the feed sheet 21 cooperates with the inner wall of the material guide barrel 11, the liquid cosmetics in the storage tank 1 can be isolated at the upper end of the feed sheet 21; in order to perform quantitative control, a receiving sheet 22 can be movably connected to the screw rod 32. The receiving sheet 22 of the columnar structure is matched with the screw rod 32 at the connection point. The outer wall of the receiving sheet 22 also cooperates with the inner wall of the material guide barrel 11. Therefore, the liquid cosmetics entering from the upper end can be restricted to the upper end of the receiving sheet 22. Therefore, the space between the feed sheet 21 and the receiving sheet 22 can be adjusted to achieve the effect of quantitative control. In order to limit the distance between the feed sheet 21 and the receiving sheet 22 to achieve the effect of limiting the capacity, a nut 33 is screwed into the screw rod 32 at the lower end of the receiving sheet 22, so that the upper end surface of the nut 33 abuts against the lower end of the receiving sheet 22. The distance between the feed sheet 21 and the receiving sheet 22 can be adjusted by twisting the nut 33.

[0032] However, when the receiving sheet 22 is moving downward, if it is lower than the position of the discharge port 12, the liquid cosmetics on its upper end will move downward along with the receiving sheet 22, so that the liquid cosmetics cannot flow out completely, and the capacity limitation between the feed sheet 21 and the receiving sheet 22 is meaningless. Therefore, a limiting ring 23 is provided at the lower end of the connection between the guide barrel 11 and the discharge port 12, and the screw rod 32 and the nut 33 both pass through the middle of the limiting ring 23. The receiving sheet 22 is located at the upper end of the limiting ring 23. When the receiving piece 22 moves downward and is blocked by the limiting ring 23, the flat surface 221, the inclined surface 222 and the discharge port 12 at the upper end of the receiving piece 22 form a continuous discharge cavity, and the screw 32 continues to move downward along with the nut 33, driving the feed piece 21 to continue to press down the liquid cosmetics in the guide cylinder 11 and flow out smoothly along the discharge cavity, and the liquid cosmetics will not accumulate at the upper end of the receiving piece 22, so that quantitative control can be achieved. The downward movement limit of the cylinder 31 is that the feed piece 21 will not be lower than the discharge port 12, This can prevent the liquid cosmetics on the upper end of the feed sheet 21 from flowing out of the discharge port 12. Since the receiving sheet 22 can prevent the liquid cosmetics from penetrating downward from the gap between it and the guide barrel 11, the lower end surface of the guide barrel 11 is downwardly open, which can facilitate the nut 33 to pass through the guide barrel 11 as the screw rod 32 moves downward, and it is also convenient to screw the nut 33 up and down to adjust the quantitative position; in order to ensure that the flat surface 221, the inclined surface 222 and the discharge port 12 on the receiving sheet 22 can form For a continuous discharge cavity, it is necessary to limit the lateral position of the receiving piece 22. Therefore, a vertical limiting column 24 is arranged in the material guiding cylinder 11. The limiting column 24 cooperates with the limiting groove 223 on the outer wall of the receiving piece 22. Therefore, the receiving piece 22 will move up and down along the direction of the limiting column 24 during the up and down movement. At the same time, a matching hole 211 that cooperates with the limiting column 24 is provided on the feeding piece 21, so that the feeding piece 21 can still keep the liquid cosmetics on its upper end isolated during the downward movement.

[0033] In order to achieve the position limitation of the upward and downward movement limits of the cylinder 31, a buffer ring 51 and a touch head 52 are added. The buffer ring 51 is embedded in the material guide cylinder 11 and is located between the storage tank 1 and the discharge port 12. After the supporting piece 22 moves up to its flat surface 221 and abuts against the buffer ring 51, the cylinder 31 stops immediately, so that the upward movement position of the supporting piece 22 is limited. When the feed piece 21 passes over the buffer ring 51 up and down, since the feed piece 21 itself is a soft structure like silicone, it can easily pass over the buffer ring 51 up and down without affecting its effect of limiting the liquid cosmetics. The touch head 52 is arranged in the support cover 42. When the connecting plate 34 moves down to touch the touch head 52, it is the downward movement limit of the cylinder 31.

[0034] Therefore, the working process of the manual filling machine is as follows: the liquid cosmetics are loaded into the storage tank 1 and set aside, and the screw rod 32 is pushed upward by manually starting the cylinder 31, and the nut 33 on the screw rod 32 will also lift the receiving piece 22 to move upward until the feed piece 21 extends into the storage tank 1, and the liquid cosmetics enter the gap between the feed piece 21 and the guide barrel 11 and are filled between the feed piece 21 and the receiving piece 22. Because it is a liquid cosmetic, its filling speed is fast and there will be no gap. After the filling is completed, the screw rod 32 is moved downward, so that the feed piece 21 moves downward and enters the guide barrel 11, and the receiving piece 22 also moves downward synchronously, and the feed piece 21 and the receiving piece 22 are filled. The space between them is the quantitative capacity. During the downward movement, the receiving sheet 22 first moves downward through the discharge port 12, and part of the liquid cosmetics on it will flow out through the discharge port 12 first. The receiving sheet 22 that continues to move downward abuts on the limiting ring 23, and the screw 32 and the nut 33 continue to move downward, so that the feed sheet 21 continues to be pressed downward, and the liquid cosmetics at its lower end flows out from the discharge cavity. After the discharge is completed, the screw 32 is moved up again until the nut 33 abuts against the lower end of the receiving sheet 22 again and moves up for refilling. When the nut 33 moves to the lowest end, the nut 33 can be twisted to adjust the distance between the nut 33 and the feed sheet 21, thereby changing the capacity.

[0035] The beneficial effect of the utility model is that the screw rod 32 is driven up and down by the cylinder 31 to realize the process of filling, feeding and discharging. The inclined receiving piece 22 can facilitate the timely discharge of the liquid cosmetics thereon from the discharge port 12, and the nut 33 on the screw rod 32 is adjusted up and down to change the distance between the receiving piece 22 and the feeding piece 21, thereby changing the size of the space therebetween, and finally realizing the effect of quantitative adjustment. By manually starting the cylinder 31, quantitative filling of liquid cosmetics can be carried out, which can be used in trial production or small batch production. Its power consumption is only that of the drive of the cylinder 31, so the use cost is low and the quantitative adjustment is simple.

[0036] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
