Description

Technical Field

[0001] The invention relates to the technical field of toothpaste filling, and in particular to an automatic filling device based on toothpaste production. Background Art

[0002] The process flow of toothpaste production includes three main steps: paste making, filling and packaging.

[0003] Paste making is a key link in toothpaste production, and the paste making process can be divided into multiple steps, including metering, glue making, paste kneading, grinding, vacuum degassing, aging, etc. The main task of this stage is to mix various raw materials according to the formula ratio, and through grinding and vacuum degassing and other processes, make the paste reach the required uniformity and stability.

[0004] Filling is the process of pouring the toothpaste into an empty tube and capping and sealing it with a filling machine. This process requires highly automated production line operations to ensure that each tube is completely closed to ensure the hygiene and safety of the product.

[0005] Packaging is the final packaging of toothpaste after filling, including color boxes, outer packaging films, etc., which not only increases the aesthetics of the product, but also protects the product from pollution and damage.

[0006] Among them, the filling process mostly adopts the process of filling toothpaste from the end of the toothpaste tube away from the toothpaste cap. Automated equipment is used to insert the filling tube into the toothpaste tube, and then the filling tube is pulled out of the toothpaste tube while completing the extrusion and filling of the toothpaste. After the filling is completed, the sealing equipment is used to curl and seal the end of the toothpaste tube away from the toothpaste cap. There are problems with the existing toothpaste filling technology: since curling and sealing are required after filling, and the sealing area is large, the toothpaste filling amount cannot be filled. Filling will cause a large amount of toothpaste to overflow during the sealing process. Solving this problem can reduce the raw material input for each toothpaste tube based on the rated single toothpaste can weight.

[0007] The Chinese invention patent with the announcement number CN114229066B: A device for toothpaste canning, which discloses a technical solution for realizing intermittent discharging and sealing the toothpaste can by cooperating between an intermittent discharging mechanism and a sealing mechanism;

[0008] The Chinese invention patent with announcement number CN100460283C: A double-row toothpaste packaging production line and its configuration method, which discloses a technical solution that can produce two different specifications of toothpaste at the same time, and can shut down one side to save energy when the production capacity is insufficient, thereby improving the comprehensive utilization rate of the equipment;

[0009] The Chinese utility model patent with announcement number CN216186506U: A toothpaste filling device discloses a technical solution in which the guide block of the support seat can drive the support seat to rotate under the guidance of the guide groove. After the toothpaste tube is filled, the support seat rotates when it is away from the filling tube to force the toothpaste wire drawing to automatically disconnect.

[0010] The above patents are unable to achieve technological progress in reducing toothpaste waste and reducing the cost of toothpaste tubes by improving the filling process. Therefore, the art urgently needs automated filling equipment based on toothpaste production to solve the problems existing in the prior art. Summary of the invention

[0011] The purpose of the present invention is to provide an automated filling device based on toothpaste production to solve the technical problems in the prior art of waste in toothpaste filling and high cost of toothpaste tubes.

[0012] In order to achieve the above object, the present invention provides the following technical solutions:

[0013] The automated filling equipment based on toothpaste production includes a frame assembly and a filling assembly installed in the frame assembly, wherein a transmission member is installed on the top of the filling assembly; the frame assembly includes at least three arc-shaped side panels arranged in a circumferential array, wherein the tops of all the arc-shaped side panels are fixedly connected to a top panel, and the bottoms of all the arc-shaped side panels are fixedly connected to a connecting plate; at least three first connecting rods are fixedly installed on the bottom of the connecting plate in a circular array, and the bottoms of all the first connecting rods are fixedly connected to a bottom plate; a first sleeve is vertically penetrated and fixed in the center of the connecting plate, and a second sleeve is vertically penetrated and fixed in the center of the bottom plate, and the frame assembly is fixedly connected to an external mounting platform, so that the filling equipment is suspended and fixed;

[0014] The filling assembly includes an inner sleeve filling tube with an inner filling hole extending through the side wall, an outer sleeve filling tube being sleeved on the outside of the inner sleeve filling tube, an outer filling hole extending through the side wall of the outer sleeve filling tube, a bottom cover being fixedly installed on the bottom end of the outer sleeve filling tube, the outer sleeve filling tube being vertically slidably installed inside the first sleeve tube and the second sleeve tube at the same time, a bottom filling hole extending through the middle height position of the bottom cover, a feeding hose being fixedly connected to the top end of the inner sleeve filling tube, the feeding hose being connected to an external automatic toothpaste supply device at one end away from the inner sleeve filling tube, and a transmission member being fixedly connected to the top end of the outer wall of the inner sleeve filling tube; the transmission member can drive the inner sleeve filling tube to make reciprocating motion in the vertical direction.

[0015] As a preferred solution, the transmission member includes an upper transmission plate, a lower transmission plate, and a second connecting rod. At least three second connecting rods are fixedly installed in a circular array on the bottom surface of the upper transmission plate. A lower transmission plate is fixedly installed on the bottom ends of all the second connecting rods. The lower transmission plate is fixedly connected to the outer wall of the inner sleeve filling tube, and the upper transmission plate is transmission-connected to the external power source equipment.

[0016] As a preferred solution, a number of metal springs are fixedly installed in a circular array at the bottom end of the second sleeve, the gap between adjacent metal springs is less than 1 mm, and the bottom area of ​​the metal springs is flanged away from the axis of the inner sleeve filling tube, so that the bottom of the metal spring has an arc-shaped structure. When the bottom cover and the outer sleeve filling tube move downward, the bottom end of the metal spring can be pushed outward. At this time, the area of ​​the metal spring close to the bottom cover or the outer sleeve filling tube is an arc-shaped convex surface, so that the metal spring will not be stuck with the outer filling hole, so that the outer sleeve filling tube can be displaced vertically smoothly.

[0017] As a preferred embodiment, the filling equipment also includes a sliding limit assembly, which includes a limit slide groove opened on the top of the side wall of the outer sleeve filling tube, and a limit protrusion fixed on the side wall of the inner sleeve filling tube. The limit protrusion vertically slides and fits inside the limit slide groove, so that the inner sleeve filling tube can drive the outer sleeve filling tube upward, and at the same time can avoid the coaxial relative rotation of the outer sleeve filling tube and the inner sleeve filling tube. When the inner filling hole and the outer filling hole need to communicate with each other, the inner filling hole and the outer filling hole will not be misaligned and can be coaxially aligned.

[0018] As a preferred solution, the outer sleeve filling tube has a diameter of 5-7 mm, so that the method of filling toothpaste into the toothpaste tube from the paste outlet can be applied to most toothpaste tube diameters, which can not only ensure the toothpaste circulation efficiency, but also leave a gap between the outer sleeve filling tube and the inner filling hole for the gas in the toothpaste tube to be discharged.

[0019] As a preferred solution, the distance between the bottom end of the metal shrapnel and the axis of the second sleeve is smaller than the distance between the top end of the metal shrapnel and the axis of the second sleeve, so that all the metal shrapnel are combined to form an approximately inverted cone-shaped whole. When the method of filling the toothpaste tube with toothpaste from the paste outlet direction is adopted, the metal shrapnel and the second sleeve can be efficiently inserted into the paste outlet, and the matching connection with the paste outlet is highly accurate.

[0020] As a preferred solution, the diameter of the inner filling hole at a high position is smaller than the diameter of the inner filling hole at a low position; in the process of the toothpaste paste being squeezed downward from the top of the inner sleeve filling tube, most of the paste is prevented from being squeezed out from the inner filling hole at a high position, thereby preventing the inner filling hole at a low position from losing its function.

[0021] As a preferred solution, the wall thickness of the bottom cover is greater than the wall thickness of the outer casing filling tube, and the diameter of the top end of the outer wall of the bottom cover is equal to the diameter of the outer wall of the outer casing filling tube.

[0022] As a preferred solution, the bottom cover is a hollow hemisphere with the concave surface facing upward, and the outer sleeve filling tube is integrally formed with the bottom cover.

[0023] As a preferred solution, a transmission hole is vertically penetrated through the center of the top plate, and an external power source device can use a rod to drive the transmission member in a vertical direction through the transmission hole.

[0024] As a preferred solution, automated programming is used to set the cyclic driving process of the transmission parts by the external power source equipment, and the toothpaste supply positive pressure of the external toothpaste automatic supply equipment is set according to the diameter of the toothpaste tube. When filling large-diameter toothpaste tubes, the toothpaste supply pressure parameters are increased, that is, the toothpaste flow efficiency is improved. When filling small-diameter toothpaste tubes, the toothpaste supply pressure parameters are reduced.

[0025] Toothpaste filling includes the following steps:

[0026] 1. Tube embedding: first, insert the metal spring and the second sleeve tube into the inside of the toothpaste outlet. This process can be automated by relying on the external toothpaste tube clamping equipment. The external power source equipment drives the transmission part, thereby driving the inner sleeve filling tube and the outer sleeve filling tube to move downward. In this process, the outer sleeve filling tube can be subjected to the resistance caused by the clamping of the metal spring, so that the inner sleeve filling tube can be inside the outer sleeve filling tube and move downward relative to the outer sleeve filling tube until the bottom end of the inner sleeve filling tube hits the top of the bottom cover, thereby driving the bottom cover and the outer sleeve filling tube to move downward together, and at the same time, the bottom end of the metal spring can be stretched outward. After the inner filling hole and the outer filling hole are completely immersed in the toothpaste tube, the inner sleeve filling tube and the outer sleeve filling tube stop moving downward.

[0027] 2. Basic filling link: after the inner filling tube and the outer filling tube stop moving downward, the external toothpaste automatic supply equipment feeds toothpaste into the inner filling tube at high pressure, and the toothpaste is squeezed out from the inner filling hole and the outer filling hole. Because the toothpaste is pushed by the high pressure, it has a tendency to fill the area near the inner wall of the toothpaste tube. Therefore, after filling for 2-3 seconds, the toothpaste density near the inner wall of the toothpaste tube is greater than the toothpaste density in the center of the toothpaste tube;

[0028] 3. Filling and filling stage: After the basic filling stage lasts for 2-3 seconds, the external toothpaste automatic supply equipment reduces the toothpaste supply pressure to the inner sleeve filling tube, and at the same time, the external power source equipment indirectly drives the inner sleeve filling tube to lift up. The lifting time lasts for 1.5-2 seconds. During the lifting process of the inner sleeve filling tube, the friction between the inner sleeve filling tube wall and the outer sleeve filling tube wall is less than the friction resistance caused by the metal shrapnel to the outer sleeve filling tube. Therefore, when the inner sleeve filling tube starts to be lifted, it will move upward relative to the outer sleeve filling tube, so that the inner filling hole and the outer filling hole are staggered. At this time, only the bottom filling hole can continue to flow into the toothpaste tube. Fill toothpaste; at the same time, when the inner filling tube just starts to be lifted up, the limiting protrusion slides from the bottom end of the limiting slide groove to the top end of the limiting slide groove, and then the limiting protrusion pushes the outer filling tube upward, and the inner filling tube and the outer filling tube move up at a uniform speed, while the bottom filling hole fills the center of the toothpaste tube in the vertical direction; in the process of the outer filling tube moving up, the metal spring can scrape off the toothpaste attached to the outer wall of the outer filling tube, and after the inner filling tube and the outer filling tube are completely moved up and reset, the toothpaste filling of a toothpaste tube is completed; with the help of automated programs and external auxiliary transmission equipment, the filling efficiency can be further improved.

[0029] As a preferred solution, the length of the metal shrapnel is greater than the length of the paste outlet. During filling, all the metal shrapnel are inserted into the paste outlet, and the upper and lower ends of the metal shrapnel protrude from the upper and lower ends of the paste outlet respectively. With this solution, even if the metal shrapnel is expanded by the outer sleeve filling tube and the outer wall is in close contact with the paste outlet, the gap between the metal shrapnel can be used to vent the inside of the toothpaste tube to the outside, so that this solution can maximize the diameter of the outer sleeve filling tube and the inner sleeve filling tube under the limited diameter condition of the paste outlet, thereby improving the filling efficiency and the applicability to toothpaste tubes with small-diameter paste outlets.

[0030] Beneficial effects:

[0031] 1. This solution reduces the waste in the toothpaste filling process and reduces the cost of toothpaste tubes by improving the filling process;

[0032] 2. This solution can directly fill the toothpaste from the toothpaste mouth, so that the toothpaste tube can be directly produced and then filled, and then sealed and capped after filling, which improves the filling degree of toothpaste into the toothpaste tube;

[0033] 3. After the toothpaste filling is completed, the toothpaste attached to the surface of the outer filling tube can be effectively scraped off inside the toothpaste tube, and the scraped toothpaste can be retained inside the toothpaste tube;

[0034] 4. This equipment is small in size and low in cost, and can be afforded by both large and small enterprises. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0051] Embodiment 1, as Figure 1-Figure 11 As shown, the automated filling equipment based on toothpaste production includes a frame assembly and a filling assembly installed in the frame assembly, and a transmission member is installed on the top of the filling assembly; the frame assembly includes three arc-shaped side panels 101 arranged in a circular array, and the tops of all the arc-shaped side panels 101 are commonly fixedly connected to a top plate 102, and the bottoms of all the arc-shaped side panels 101 are commonly fixedly connected to a connecting plate 103; three first connecting rods 104 are fixedly installed in a circular array at the bottom of the connecting plate 103, and the bottoms of all the first connecting rods 104 are commonly fixedly connected to a bottom plate 105; a first sleeve 107 is vertically penetrated and fixed in the center of the connecting plate 103, and a second sleeve 108 is vertically penetrated and fixed in the center of the bottom plate 105, and the frame assembly is fixedly connected to an external mounting platform, so that the filling equipment is suspended and fixed;

[0052] The filling assembly includes an inner sleeve filling tube 301 with an inner filling hole 302 extending through the side wall, an outer sleeve filling tube 303 is sleeved on the outside of the inner sleeve filling tube 301, an outer filling hole 304 is extended through the side wall of the outer sleeve filling tube 303, a bottom cover 305 is fixedly installed at the bottom end of the outer sleeve filling tube 303, the outer sleeve filling tube 303 is vertically slidably installed inside the first sleeve 107 and the second sleeve 108 at the same time, a bottom filling hole 306 is extended through the middle height position of the bottom cover 305, a feeding hose 307 is fixedly connected to the top end of the inner sleeve filling tube 301, and the feeding hose 307 is connected to an external toothpaste automatic supply device at one end away from the inner sleeve filling tube 301, and a transmission member is fixedly connected to the top end of the outer wall of the inner sleeve filling tube 301; the transmission member can drive the inner sleeve filling tube 301 to make reciprocating motion in the vertical direction.

[0053] The transmission parts include an upper transmission plate 201, a lower transmission plate 202, and a second connecting rod 203. Three second connecting rods 203 are fixedly installed in a circular array on the bottom surface of the upper transmission plate 201. A lower transmission plate 202 is fixedly installed at the bottom ends of all the second connecting rods 203. The lower transmission plate 202 is fixedly connected to the outer wall of the inner sleeve filling tube 301, and the upper transmission plate 201 is connected to the external power source equipment.

[0054] A plurality of metal springs 401 are fixedly installed in a circular array at the bottom end of the second sleeve 108, and the gap between adjacent metal springs 401 is 0.9 mm. The bottom area of ​​the metal springs 401 is flanged away from the axis of the inner sleeve filling tube 301, so that the bottom of the metal springs 401 has an arc structure. When the bottom cover 305 and the outer sleeve filling tube 303 move downward, the bottom of the metal springs 401 can be pushed outward. At this time, the area of ​​the metal springs 401 close to the bottom cover 305 or the outer sleeve filling tube 303 is an arc-shaped convex surface, so that the metal springs 401 will not be stuck with the outer filling hole 304, so that the outer sleeve filling tube 303 can be smoothly displaced vertically.

[0055] The filling equipment also includes a sliding limit assembly, which includes a limit slot 501 opened on the top of the side wall of the outer sleeve filling tube 303, and a limit protrusion 502 fixed on the side wall of the inner sleeve filling tube 301. The limit protrusion 502 vertically slides and fits inside the limit slot 501, so that the inner sleeve filling tube 301 can drive the outer sleeve filling tube 303 upward, and at the same time, it can avoid the coaxial relative rotation of the outer sleeve filling tube 303 and the inner sleeve filling tube 301. When the inner filling hole 302 and the outer filling hole 304 need to communicate with each other, the inner filling hole 302 and the outer filling hole 304 will not be misaligned and can be coaxially aligned.

[0056] The outer outer filling tube 303 has a diameter of 6 mm, so that the method of filling toothpaste into the toothpaste tube 601 from the paste outlet 602 can be applied to most toothpaste tube diameters, which can not only ensure the toothpaste circulation efficiency, but also leave a gap between the outer outer filling tube 303 and the inner filling hole 302 for the gas in the toothpaste tube 601 to be discharged.

[0057] The distance between the bottom end of the metal shrapnel 401 and the axis of the second sleeve 108 is smaller than the distance between the top end of the metal shrapnel 401 and the axis of the second sleeve 108, so that all the metal shrapnel 401 are combined to form an approximately inverted cone-shaped whole. When the method of filling the toothpaste tube 601 with toothpaste from the direction of the paste outlet 602 is adopted, the metal shrapnel 401 and the second sleeve 108 can be efficiently inserted into the paste outlet 602, and the matching connection with the paste outlet 602 is highly accurate.

[0058] The aperture of the inner filling hole 302 at a high position is smaller than that of the inner filling hole 302 at a low position; in the process of the toothpaste paste being squeezed downward from the top of the inner sleeve filling tube 301, most of the paste is prevented from being squeezed out from the inner filling hole 302 at a high position, thereby preventing the inner filling hole 302 at a low position from losing its function.

[0059] The wall thickness of the bottom cover 305 is greater than that of the outer casing filling tube 303 , and the diameter of the top of the outer wall of the bottom cover 305 is equal to the diameter of the outer wall of the outer casing filling tube 303 .

[0060] The bottom cover 305 is a hollow hemispherical body with the concave surface facing upwards, and the outer sleeve filling tube 303 and the bottom cover 305 are integrally formed.

[0061] A transmission hole 106 is vertically penetrated through the center of the top plate 102 , and an external power source device can use a rod to drive the transmission member in a vertical direction through the transmission hole 106 .

[0062] Automatic programming is used to set the cyclic driving process of the transmission parts by the external power source equipment, and the toothpaste supply positive pressure of the external toothpaste automatic supply equipment is set according to the diameter size of the toothpaste tube 601. When filling the large-diameter toothpaste tube 601, the toothpaste supply pressure parameter is increased, that is, the toothpaste flow efficiency is improved. When filling the small-diameter toothpaste tube 601, the toothpaste supply pressure parameter is reduced.

[0063] Toothpaste filling includes the following steps:

[0064] 1. Tube embedding: first, insert the metal spring piece 401 and the second sleeve 108 into the toothpaste outlet 602. This process can be automated by relying on the external toothpaste tube clamping equipment. The external power source equipment drives the transmission part, thereby driving the inner sleeve filling tube 301 and the outer sleeve filling tube 303 to move downward. In this process, the outer sleeve filling tube 303 can be subjected to the resistance caused by the clamping of the metal spring piece 401, so that the inner sleeve filling tube 301 can move downward inside the outer sleeve filling tube 303 and relative to the outer sleeve filling tube 303 until the bottom end of the inner sleeve filling tube 301 hits the top of the bottom cover 305, thereby driving the bottom cover 305 and the outer sleeve filling tube 303 to move downward together, and at the same time, the bottom end of the metal spring piece 401 can be stretched outward. After the inner filling hole 302 and the outer filling hole 304 are completely immersed in the toothpaste tube 601, the inner sleeve filling tube 301 and the outer sleeve filling tube 303 stop moving downward.

[0065] 2. Basic filling process: after the inner filling tube 301 and the outer filling tube 303 stop moving downward, the external toothpaste automatic supply equipment feeds toothpaste into the inner filling tube 301 at high pressure, and the toothpaste is squeezed out from the inner filling hole 302 and the outer filling hole 304. Since the toothpaste is pushed by the high pressure, it has a tendency to fill the area near the inner wall of the toothpaste tube 601. Therefore, after 2.5 seconds of filling, the toothpaste density near the inner wall of the toothpaste tube 601 is greater than the toothpaste density in the center of the toothpaste tube 601.

[0066] 3. Filling link: After the basic filling link lasts for 2.5 seconds, the external toothpaste automatic supply equipment reduces the toothpaste supply pressure to the inner sleeve filling tube 301, and at the same time, the external power source equipment indirectly drives the inner sleeve filling tube 301 to be lifted up, and the lifting time lasts for 1.8 seconds. During the lifting process of the inner sleeve filling tube 301, the friction between the tube wall of the inner sleeve filling tube 301 and the tube wall of the outer sleeve filling tube 303 is less than the friction resistance caused by the metal spring 401 to the outer sleeve filling tube 303. Therefore, when the inner sleeve filling tube 301 starts to be lifted up, it will move upward relative to the outer sleeve filling tube 303, so that the inner filling hole 302 and the outer filling hole 304 are staggered. At this time, only the bottom filling hole 306 can continue to fill the toothpaste into the toothpaste tube 601; When the inner filling tube 301 just starts to be lifted up, the limiting protrusion 502 slides from the bottom end of the limiting slide groove 501 to the top end of the limiting slide groove 501, and then the limiting protrusion 502 pushes the outer sleeve filling tube 303 upward, and the inner filling tube 301 and the outer sleeve filling tube 303 move up at a uniform speed, while the bottom filling hole 306 fills the center of the toothpaste tube 601 in the vertical direction; in the process of the outer sleeve filling tube 303 moving up, the metal spring 401 can scrape off the toothpaste attached to the outer wall of the outer sleeve filling tube 303, and after the inner filling tube 301 and the outer sleeve filling tube 303 are completely moved up and reset, the toothpaste filling of a toothpaste tube 601 is completed; with the help of automated procedures and external auxiliary transmission equipment, the filling efficiency can be further improved.

[0067] Embodiment 2, on the basis of the technical scheme of embodiment 1, the length of the metal shrapnel 401 is greater than the length of the paste outlet 602. During filling, all the metal shrapnel 401 are inserted into the paste outlet 602, and the upper and lower ends of the metal shrapnel 401 protrude from the upper and lower ends of the paste outlet 602 respectively. With this scheme, even if the metal shrapnel 401 is expanded by the outer sleeve filling tube 303, and the outer wall is in close contact with the paste outlet 602, the gap between the metal shrapnel 401 can be used to vent the inside of the toothpaste tube 601 to the outside, so that this scheme can maximize the diameter of the outer sleeve filling tube 303 and the inner sleeve filling tube 301 under the condition of the limited diameter of the paste outlet 602, thereby improving the filling efficiency and the applicability to the toothpaste tube 601 with a small-diameter paste outlet 602.

[0068] Embodiment 3, as Fig.12As shown, based on the technical solution of Example 1, the technical solution of burying the tube in the first step of toothpaste filling: the metal spring 401 and the second sleeve 108 are inserted into the inside of the toothpaste outlet 602, is replaced by: the metal spring 401 and the second sleeve 108 are inserted into the end of the toothpaste tube 601 away from the toothpaste outlet 602. This allows the present solution to be applied to the common filling method of the prior art: after filling from the bottom of the toothpaste tube 601, the bottom of the toothpaste tube 601 is sealed.

[0069] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
