Description

Technical Field

[0001] This invention relates to a fish oil nutritional paste for preventing pet hair loss, as well as its low-temperature filling device and process, belonging to the technical field of fish oil nutritional paste. Background Technology

[0002] The core drawback of maintaining low-temperature filling in the current production of fish oil nutritional paste is that the filling environment temperature fluctuates greatly, the paste is prone to layering and solidification, and the sealing and label adhesion are poor. These drawbacks are caused by the lack of professional thermal insulation design, the inability of conventional refrigeration equipment to maintain a stable low-temperature field, and the poor temperature connection between filling, sealing and labeling processes. The oil phase and water phase components in the raw materials are prone to separation due to differences in solubility when the temperature changes. The abnormal increase in the viscosity of the paste at low temperatures can also lead to flow obstruction. Conventional solutions include temporarily increasing the power of refrigeration equipment, shortening the filling process time, manually adjusting the temperature and viscosity of the paste, and increasing the ambient temperature during labeling. These methods have significant drawbacks: simply increasing the refrigeration power can lead to energy waste, and excessively low local temperatures can exacerbate paste solidification; shortening the process time may result in inaccurate filling volume and insufficient sealing; manually adjusting temperature and viscosity is difficult to control precisely, easily causing uneven mixing of ingredients; increasing the labeling temperature will disrupt the low-temperature environment of the filling process, leading to a decline in paste quality. At the same time, temporary adjustments cannot fundamentally solve the temperature fluctuation problem and may also increase equipment and production losses, affecting product qualification rate and stability. Therefore, there is an urgent need for a fish oil nutritional paste that prevents pet hair shedding and its low-temperature filling device and process to solve the above problems. Summary of the Invention

[0004] The technical solution of the present invention is implemented as follows: a low-temperature filling device for fish oil nutritional paste that prevents pet hair shedding includes a top cover, a low-temperature filling component, and a discharge end. The lower end of the top cover is provided with a set of low-temperature filling components for filling fish oil nutritional paste.

The middle left side of the low-temperature filling component has a feed end for importing the fish oil nutritional paste into the bottle. The rear left side of the low-temperature filling component has two sets of material tubes for importing the raw materials of the fish oil nutritional paste to be filled. First, start the cold air compressor on the upper left side of the top cover. Using the cavity on the lower inner side of the top cover and the upper part of the low-temperature filling component, create the required low-temperature filling environment for the low-temperature filling component. Then, introduce the raw material of the fish oil nutritional paste to be filled through the two sets of material pipes on the left rear side of the low-temperature filling component. At the same time, feed the filling bottle from the feed end in the middle of the left side of the low-temperature filling component. Then, use the guide component to fill and guide the bottle and paste. During the process, the limiting strips on the front and rear sides of the upper end of the guide component limit the position of the bottle, and the support legs support the bottom of the guide component. After filling is completed, the filled bottle is discharged from the discharge end in the middle of the right side of the low-temperature filling component, thus completing the entire filling operation process.

At the lower end of the limiting component, there is a set of motor housing for providing rotational power. Inside the motor housing, there is a set of drive motors. In actual use, the low-temperature filling component and the internal components of the conveying cavity work together to have many beneficial effects. The outer insulation layer on the inner side of the outer protective shell and the inner insulation layer on the inner side of the inner pipe cavity constitute a double insulation design, which can effectively prevent the cold air inside the conveying cavity from dissipating. The annular low-temperature air circulation pipe inside the inner pipeline cavity can evenly deliver low-temperature cold air. The two work together to ensure that the delivery cavity always maintains a stable low-temperature filling environment, avoiding problems such as layering and abnormal viscosity of fish oil nutritional paste due to temperature fluctuations, thus ensuring the quality of the paste. The temperature sensor inside the temperature sensor bracket can monitor the release temperature of the cold air release pipe in real time, which can facilitate timely adjustment of the refrigeration state and improve the control accuracy of the low-temperature environment. The side limit bracket can fix the position of the cold air release pipe. The inner insulation layer and the inner protective shell with the inner perforation and the inner sealing lining can prevent cold air leakage. The two work together to avoid cold air waste and ensure the stable operation of the cold air release pipe, reducing the risk of equipment failure. The filling component on the left side of the guide cavity can complete the filling of fish oil nutritional paste, the labeling component on the right side of the guide cavity can realize the hot stamping of the label on the outside of the bottle, the capping component on the right side of the labeling component can complete the sealing of the cap at the bottle opening, the limiting component can limit and guide multiple groups of bottles in the process, and the drive motor inside the motor box can provide stable power for the limiting component. The two work together to ensure that the bottle moves in an orderly manner in the guide cavity and avoid the bottle deviating.

[0007] In a preferred embodiment, the filling component includes an inner frame and a mixing tube. The inner frame is a rectangular structure and has two sets. The rear inner frame is a fixed structure, while the front inner frame is a movable structure. Each set of inner frames has a clamping frame at its lower end for positioning the bottle to be filled. The two sets of clamping frames are arranged symmetrically. The inner side of the clamping frames is provided with several sets of positioning and filling grooves for positioning and fitting the upper end of the filling bottle. The positioning and filling grooves are arc-shaped. When the distance between the two sets of clamping frames and the inner frame is shortened, the two sets of positioning and filling grooves form an elliptical overall filling groove. The left inner end of the two sets of inner frames is provided with a set of clamping electric cylinders one for adjusting the distance between them, and the right inner end of the two sets of inner frames is provided with a set of clamping electric cylinders two for adjusting the distance between them. The clamping electric cylinders one and two have the same structure and move synchronously. The clamping electric cylinder one and clamping electric cylinder two are connected and fixed to the front inner frame by bolts. The driving ends of clamping electric cylinder one and clamping electric cylinder two are both located on the rear side and are connected and fixed to the rear inner frame by bolts. Several sets of filling heads for filling fish oil nutritional paste are provided in the middle position between the two sets of inner frames. The number of filling heads corresponds to the number of filling tanks in the whole. Each set of filling heads has a filling column at the upper end for guiding and supplying fish oil nutritional paste. The filling column has a control valve for controlling the filling amount and an inner cavity for storing fish oil nutritional paste raw materials. The upper end of the filling column has a buffer spring one for supporting the reverse force when the upper end of the bottle contacts. The lower end of the buffer spring has an inner locking groove at the contact position with the filling column. The upper end of each of the several sets of buffer springs is provided with an upper fixing frame for supporting its top. The upper end of each of the filling columns is provided with a conveying pipe for conveying the raw materials of fish oil nutritional paste. The conveying pipe is connected to the inner cavity. The lower outer side of the conveying pipe is provided with a fixing nut for fixing its position. The fixing nut is connected to the lower outer side of the conveying pipe by thread until the bottom of the fixing nut is in contact with the upper surface of the upper fixing frame. The upper left side of the upper fixing frame is provided with a lifting electric cylinder II for controlling the height of the upper fixing frame. The upper right side of the upper fixed frame is equipped with a set of lifting electric cylinders (first and second) for controlling the height of the upper fixed frame. Lifting electric cylinders (first and second) are of the same specifications and operate synchronously. Above the lifting electric cylinders (first and second) is a set of top beams for supporting their tops. The top beams have a hollow internal structure. Inside the top beams is a set of mixing pipes (second) for synchronously introducing other mixed raw materials of the fish oil nutritional paste. At the upper end of mixing pipes (second), there is a mixing pipe (first) for conveying the raw materials of the fish oil nutritional paste. Mixing pipes (first and second) are connected at right angles, and a mixing tee is provided at the connection point. In actual use, when the filling component is working, the two sets of inner frames, fixed at the rear and movable at the front, are on their inner left... The clamping electric cylinders 1 and 2, which move synchronously at both ends on the right, adjust their spacing under the drive, causing the symmetrical clamping frame at the lower end to move closer together. This allows the arc-shaped positioning filling grooves inside the clamping frame to be spliced ​​into an elliptical integral filling groove, thus achieving the positioning of the bottle. Inside the top beam, mixing pipe 1 and mixing pipe 2, which are connected at right angles, simultaneously introduce fish oil nutritional paste raw materials and other mixed raw materials, which are then transported to the inner cavity of the filling column through the conveying pipe. The control valve inside the filling column regulates the filling volume, and the filling head at the lower end fills the positioned bottle. Lifting electric cylinders 1 and 2, which move synchronously on the left and right sides of the upper fixed frame, can adjust the height of the upper fixed frame. The buffer spring 1 at the upper end of the filling column provides a reverse force support when the bottle contacts the container, ensuring a stable and accurate filling process.

The upper end of the connecting end is fixedly connected to the bottom of the telescopic universal joint by bolts. The lower end of the connecting end is equipped with a set of capping heads for easy installation of bottle caps of various sizes. The inner side of the capping head is equipped with a cap groove, and the inside of the cap groove is mutually positioned and fitted with the upper cap of the bottle. The middle position of the lower end of the support frame is equipped with a set of connecting support columns for supporting its bottom. In actual use, when the capping component is working, the support frame is supported by the connecting support columns. The bottom is stably supported, and an adjustable electric cylinder with a fixed plate is installed at the top. This cylinder drives the telescopic column to move the movable seat plate up and down. The movable fitting seat on the right side of the movable seat plate engages with the guide rail to ensure precise guidance when the movable seat plate moves. The upper front end of the movable seat plate is bolted to the support frame, which in turn supports the capping motor. The lower end of the capping motor is connected to the connecting end via a telescopic universal joint. The buffer spring on the outside of the telescopic universal joint can buffer the reverse force during capping. The cap tightening head installed at the lower end of the connecting end is positioned and engaged with the cap body at the top of the bottle through the inner cap groove. The capping motor drives the cap tightening head to rotate and complete the capping. In the entire process, all components work together to achieve precise positioning and stable capping of the bottle and cap. The buffer structure can prevent damage to the cap or bottle, and the guiding structure ensures operational accuracy, ultimately achieving a high-efficiency and high-quality capping effect and ensuring that the product's sealing performance meets the standards.

[0009] In a preferred embodiment, the limiting component includes a locking plate and a synchronous connecting column 2. The locking plate has a circular cross-section when viewed from above. The outer side of the locking plate is uniformly provided with several sets of locking grooves for mutually limiting and fitting with the outer side of the bottle body. The several sets of locking grooves are arranged in a ring structure. The cross-section of the several sets of locking grooves when viewed from above is an arc-shaped semi-circular structure. Each set of the chuck slots has a set of reinforcing liner plates on the outer side of the upper end to enhance the strength of the outer side of the chuck slots. The reinforcing liner plates are fixed to the chuck disc by bolts. The upper end of the middle position of the chuck disc has a set of fixing flanges to provide transmission effect. The fixing flanges are fixed to the chuck disc by several sets of bolts. The middle position of the fixing flange has a set of core rods to transmit the power inside the motor box. The core rods pass through the fixing flanges and are fixed to them. The lower end of the card head plate is evenly distributed with several sets of synchronous connecting posts 2 for connecting and fixing with the bottle carding plate 1. The lower end of the several sets of synchronous connecting posts 2 is provided with a bottle carding plate 1 for rotating and guiding the filling bottle body. The outer side of the bottle carding plate 1 is evenly distributed with several sets of bottle carding grooves 1 for providing fitting and positioning to the outer side of the filling bottle body. The number of bottle carding grooves 1 is the same as the number of card head grooves. The inner diameter of the bottle carding groove 1 in the top view cross-section is greater than the inner diameter of the card head groove in the top view cross-section.

[0010] In a preferred embodiment, the lower end of the bottle-holding disc is provided with several sets of synchronous connecting posts 1 for connecting and fixing it to the bottle-holding disc 2. The lower end of the several sets of synchronous connecting posts is provided with a set of bottle-holding disc 2 for driving the outer side of the bottom of the filling bottle to rotate. The bottle-holding disc 1 and bottle-holding disc 2 are of the same specifications, and the bottle-holding disc 2 is evenly provided with several sets of bottle-holding grooves 2. The bottle-holding grooves 1 and bottle-holding grooves 2 are of the same specifications and are completely overlapped in the vertical direction. The center position of both the bottle-holding disc 1 and bottle-holding disc 2 is provided with a set of rod grooves for the core rod to pass through. The lower end of the core rod is provided with a set of driven gears for power transmission. The middle position of the driven gear is connected and fixed to the outer side of the lower end of the core rod. A set of driving gears for power connection is provided on the front side of the driven gear. The driving gears mesh with the driven gears. A set of drive rods for transmitting power is provided at the lower end of the middle position of the driven gear. The lower end of the drive rods passes through the inside of the motor box. The motor box contains a rotary motor for providing rotation for several sets of filling bottles. A set of universal joints is provided at the connection between the driven gear and the drive rods. A set of base plates for supporting the universal joints is provided on the outer side of the lower end of the universal joints. Four sets of stable support frames are provided at the lower end of the base plates for stable support. In actual use, the rotary motor in the motor box drives the driven gear through the drive rods and universal joints. After meshing with the driving gears, the driven gears are efficiently transmitted through the core rod. With the synchronous rotation structure formed by the clamping head plate, the first clamping plate, and the second clamping plate through the synchronous connecting columns one and two, the rotation speed of multiple sets of components can be kept consistent, avoiding positional deviation caused by speed deviation during bottle conveying, and providing a stable bottle conveying state for subsequent processes. In terms of positioning and limiting, the arc-shaped semi-circular groove on the outer side of the clamping head plate vertically overlaps with the bottle clamping grooves on the first and second bottle clamping plates. The inner diameter of the bottle clamping groove is adapted to the bottom of the bottle body, and the clamping head groove is adapted to the upper middle part of the bottle body, achieving dual positioning of the upper and lower ends of the bottle body. At the same time, the reinforcing liner on the outer side of the clamping head groove increases the strength of the groove body and prevents the groove body from deforming after long-term use, thus affecting the positioning accuracy and effectively preventing the bottle body from shaking or tilting during rotation and conveying. In terms of structural support, the base plate and four sets of stable support structures form a solid bottom support system, reducing vibration when components rotate and further improving overall operational stability. This not only reduces the risk of equipment failure but also ensures that each process can be precisely connected, ultimately improving production efficiency and product qualification rate, and meeting the needs of large-scale, high-precision production of anti-pet hair shedding fish oil nutritional paste.

[0011] A process for filling fish oil nutritional paste using a low-temperature filling device includes the following steps: S1: The temperature environment is controlled at 0-5℃. This temperature range needs to be maintained stably, with fluctuations not exceeding ±0.5℃. In the raw material pretreatment stage, the basic raw materials of fish oil nutritional paste and the auxiliary mixing raw materials are introduced into the internal cavity of the top beam through mixing pipe one and mixing pipe two, respectively. The raw materials need to be filtered through an 80-mesh filter in advance to remove impurities with a particle size greater than 0.18mm. After the cold air compressor starts, it continuously delivers cold air to the delivery chamber through the low-temperature air circulation pipe. The temperature sensor monitors the internal temperature of the delivery chamber in real time. When the temperature is higher than 5°C, the cold air compressor automatically increases its power, and when it is lower than 0°C, it reduces its output to ensure that the insulation layer between the inner pipe chamber and the delivery chamber plays its role and prevents the cold air from dissipating. At the same time, the support legs adjust their height through an electric telescopic rod to keep the overall horizontal error of the device within 0.3 mm / m, ensuring the subsequent filling accuracy. S2: The temperature environment is maintained at 0-5℃, consistent with the pretreatment stage, with no temperature fluctuation deviation. The filling bottle is introduced through the feeding end. After the limiting component is activated, the drive motor drives the active gear to rotate through the drive rod, which in turn meshes with the driven gear to make the core rod rotate. The carding plate and the upper and lower bottle carding plates rotate synchronously. The head slot, bottle slot one, and bottle slot two respectively fit and position the upper, middle, and bottom of the bottle body. The inner diameter of the bottle slot is 0.2-0.3mm larger than the outer diameter of the corresponding position on the bottle body to ensure a close fit without jamming. The limiting strips are fixed by connecting support rods. The three sets of limiting strips are distributed in a straight line. The uppermost strip is located at three-quarters of the height of the bottle body, limiting the left and right deviation of the bottle body during the conveying process to no more than 0.5mm. The bottle conveying speed is set to 10-15 bottles / minute to match the subsequent filling rhythm. S3: The temperature environment is maintained at 0-3℃. This temperature can prevent the fish oil nutritional paste from becoming abnormally fluid due to excessive temperature during the filling process. Clamping cylinder one and clamping cylinder two operate synchronously, driving the two sets of inner frames to move closer to each other. The positioning filling groove on the clamping frame surrounds the elliptical integral filling groove, which is precisely aligned with the upper opening of the bottle body. The alignment deviation does not exceed 0.2mm. Lifting cylinder one and lifting cylinder two drive the upper fixed frame to descend, and the filling head slowly extends into the bottle opening to a depth of one-third of the bottle height. The delivery pipe introduces the filtered raw material into the inner cavity of the filling column. The control valve adjusts the opening and closing degree according to the preset dosage. The filling volume error of a single bottle is controlled within ±0.5g. The buffer spring provides reverse support force when the filling head contacts the bottle body. The buffer stroke is 5-8mm to avoid the bottle body being damaged by pressure. S4: Maintain the temperature environment at 0-5℃ to ensure the finished product remains at a low temperature before discharge. The labeling component hot stamps the label onto the filled bottle, with the hot stamping temperature controlled at 40-50℃ and the stamping time at 2-3 seconds to avoid high temperature affecting the quality of the paste. During the capping stage, the adjusting electric cylinder drives the movable seat plate to descend along the guide rail, and the capping screw head is positioned and engaged with the cap at the top of the bottle. The capping motor drives the capping screw head to rotate through the telescopic universal joint at a speed of 30-40 revolutions per minute. The buffer spring buffers the reverse force during the capping process, ensuring that the tightening torque of the cap is between 0.8-1.2 N·m, preventing bottle damage caused by loosening or over-tightening. After capping, the bottle clamping plate continues to rotate, exporting the finished bottle through the discharge end. During the export process, the distance between the bottles is maintained at 5-8 cm to avoid collision and wear.

The remaining component is deionized water, which accounts for 36.1% of the total composition.

[0013] After adopting the above technical solution, the beneficial effects of the device of the present invention are: in actual use, the low temperature filling component and the internal components of the delivery cavity work together to have many beneficial effects. The outer insulation layer on the inner side of the outer protective shell and the inner insulation layer on the inner side of the inner pipe cavity constitute a double insulation design, which can effectively prevent the cold air inside the delivery cavity from dissipating. The annular low-temperature air circulation pipe inside the inner pipeline cavity can evenly deliver low-temperature cold air. The two work together to ensure that the delivery cavity always maintains a stable low-temperature filling environment, avoiding problems such as layering and abnormal viscosity of fish oil nutritional paste due to temperature fluctuations, thus ensuring the quality of the paste. The temperature sensor inside the temperature sensor bracket can monitor the release temperature of the cold air release pipe in real time, which can facilitate timely adjustment of the refrigeration state and improve the control accuracy of the low-temperature environment. The side limit bracket can fix the position of the cold air release pipe. The inner insulation layer and the inner protective shell with the inner perforation and the inner sealing lining can prevent cold air leakage. The two work together to avoid cold air waste and ensure the stable operation of the cold air release pipe, reducing the risk of equipment failure. The filling component on the left side of the guide cavity can complete the filling of fish oil nutritional paste, the labeling component on the right side of the guide cavity can realize the hot stamping of the label on the outside of the bottle, the capping component on the right side of the labeling component can complete the sealing of the cap at the bottle opening, the limiting component can limit and guide multiple groups of bottles in the process, and the drive motor inside the motor box can provide stable power for the limiting component. The two work together to ensure that the bottle moves in an orderly manner in the guide cavity and avoid the bottle deviating. In actual use, when the filling component is working, the two sets of inner frames, which are fixed at the rear and movable at the front, are adjusted in distance by the clamping electric cylinders 1 and 2 moving synchronously at their inner left and right ends. This causes the symmetrical clamping frame at the lower end to move closer, so that the arc-shaped positioning filling grooves on the inner side of the clamping frame are spliced ​​into an elliptical integral filling groove, thus achieving the positioning of the bottle. The mixing pipe 1 and the mixing pipe 2, which are connected at right angles inside the top beam, simultaneously introduce the fish oil nutritional paste raw materials and other mixed raw materials, and then transport them to the inner cavity of the filling column through the conveying pipe. The control valve inside the filling column regulates the filling volume, and the filling head at the lower end fills the positioned bottle. The lifting electric cylinders 1 and 2, which move synchronously on the left and right sides of the upper fixed frame, can adjust the height of the upper fixed frame. The buffer spring 1 at the upper end of the filling column provides a reverse force support when the bottle contacts the frame, ensuring a stable and accurate filling process. In practical use, when the capping component is working, the support back frame achieves stable support at the bottom through the connecting support column. The upper end of the frame is equipped with an adjustable electric cylinder that is fixed to the plate. This cylinder can drive the telescopic column to move the movable seat plate up and down. The movable fitting seat on the right side of the movable seat plate is movablely fitted with the guide rail to ensure accurate guidance when the movable seat plate moves. The upper front end of the movable seat plate is fixed to the support base frame with bolts. The support base frame supports the capping motor. The lower end of the capping motor is connected to the connecting end via a telescopic universal joint. The buffer spring on the outside of the telescopic universal joint can buffer the reverse force during capping. The cap tightening head installed at the lower end of the connecting end is positioned and fitted with the cap body at the upper end of the bottle through the inner cap groove. The capping motor drives the cap tightening head to rotate and complete the capping. In the whole process, all components work together to achieve accurate positioning and stable capping of the bottle and cap. The buffer structure can prevent damage to the cap or bottle. The guiding structure ensures the accuracy of operation and ultimately achieves efficient and high-quality capping effect, ensuring that the product's sealing performance meets the standards. In practical use, the rotary motor inside the motor box drives the driven gear through the drive rod and universal joint. After meshing with the driving gear, the driven gear is efficiently transmitted through the core rod. Together with the chuck, bottle chuck one, and bottle chuck two, the synchronous rotation structure formed by the synchronous connecting columns one and two can ensure that the speed of multiple components is consistent, avoid the positional deviation caused by speed deviation during bottle conveying, and provide a stable bottle conveying state for subsequent processes. In terms of positioning and limiting, the arc-shaped semi-circular groove on the outer side of the clamping head plate vertically overlaps with the bottle clamping grooves on the first and second bottle clamping plates. The inner diameter of the bottle clamping groove is adapted to the bottom of the bottle body, and the clamping head groove is adapted to the upper middle part of the bottle body, achieving dual positioning of the upper and lower ends of the bottle body. At the same time, the reinforcing liner on the outer side of the clamping head groove increases the strength of the groove body and prevents the groove body from deforming after long-term use, thus affecting the positioning accuracy and effectively preventing the bottle body from shaking or tilting during rotation and conveying. The structural support system consists of a base plate and four sets of stable support structures to form a robust bottom support structure, reducing vibration during component rotation and further improving overall operational stability. This reduces the risk of equipment failure and ensures precise connection of each process, ultimately improving production efficiency and product qualification rate, and meeting the needs of large-scale, high-precision production of anti-pet hair shedding fish oil nutritional paste. After adopting the above technical solution, the beneficial effects of the process of the present invention are as follows: This process, through the combination of precise temperature control and structural design, ensures the stability of the filling quality of fish oil nutritional paste. The low temperature environment of 0-5℃ runs through the entire process, and the filling stage is further controlled at 0-3℃ to suppress the fluidity changes of raw materials caused by temperature fluctuations, reduce the layering or uneven texture of the paste, and retain the activity of effective ingredients. The temperature sensor and the cold air compressor are linked to adjust to ensure that the ambient temperature fluctuation does not exceed ±0.5℃, providing a basic guarantee for product quality. The raw material pretreatment stage uses an 80-mesh filter to remove impurities with a particle size greater than 0.18mm, reducing the risk of filling head clogging and improving product purity. Multiple positioning structures work together, with the head slot and bottle slot working in conjunction with the limiting strip to control the bottle offset within 0.5mm. The alignment deviation between the filling head and the bottle opening does not exceed 0.2mm, ensuring filling accuracy. The dosage error of a single bottle is controlled within ±0.5g. The buffer mechanism design reduces the risk of physical damage. Buffer spring one provides a 5-8mm buffer stroke to prevent breakage when the filling head contacts the bottle. Buffer spring two, in conjunction with capping torque control, prevents damage to the bottle or cap during capping. It also avoids the impact of high temperature on the quality of the ointment in low-temperature environments while completing the labeling process. After adopting the above technical solution, the beneficial effects of the ointment of the present invention are as follows: the active ingredients contained therein can repair the cell membrane of pet hair follicles, reduce dryness and breakage, and inhibit skin inflammation and relieve hair loss caused by allergies, thereby improving the health of the hair from the root. The carrier matrix can effectively prevent the nutritional paste from hardening, improve the smoothness of the paste, increase the pet's willingness to eat and provide the pet with basic energy, and help the pet easily absorb nutrients. The nutritional fortifier can enhance the pet's immunity, promote hair growth, and reduce hair loss caused by abnormal sebaceous gland secretion, further strengthening hair health. The stabilizer can ensure uniform flow during filling of the nutritional paste, improve the stable fluidity of the paste, and extend the shelf life of the product, ensuring stable quality. The remaining ingredients, as solvents, can dissolve water-soluble substances and assist each ingredient in playing its role, providing comprehensive support for the health of pet hair. Long-term use helps reduce pet hair loss and maintain a good hair condition. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-8As the first embodiment of the present invention: a low-temperature filling device for fish oil nutritional paste to prevent pet hair shedding, including a top cover 1, a low-temperature filling component 6 and a discharge end 7. The lower end of the top cover 1 is provided with a set of low-temperature filling components 6 for filling fish oil nutritional paste. The inner side of the lower end of the top cover 1 and the upper end of the low-temperature filling component 6 are provided with cavities for storing cold air compressor 2. The upper left side of the top cover 1 is provided with a set of cold air compressor 2 for providing a low-temperature filling temperature environment for the low-temperature filling component 6. The middle position inside the low-temperature filling component 6 is provided with a set of guiding components 4 for filling and conveying fish oil nutritional paste. The guiding components 4 penetrate through the center position inside the low-temperature filling component 6. The upper end of the guide component 4 is provided with a set of limiting bars 3 on the front and rear sides to limit the position of the fish oil nutritional paste filling bottle. The limiting bars 3 are distributed in a straight line and there are three sets of limiting bars 3 on the same side. The three sets of limiting bars 3 on the same side are connected and fixed by connecting support rods. The height of the uppermost limiting bar 3 is located at three-quarters of the height of the filling bottle. The lower ends of the left and right sides of the guide component 4 are provided with a set of support legs 5 to support its bottom. The right side of the support leg 5 has an inverted Y-shaped cross-section. The support leg 5 also includes a set of electric telescopic rods for adjusting the support height. The middle right side of the low-temperature filling component 6 has a set of discharge end 7 for exporting the filled bottle.

The rear left side of the low-temperature filling component 6 has two sets of material tubes for importing the raw materials of the fish oil nutritional paste to be filled. First, start the air compressor 2 on the upper left side of the top cover 1. Using the cavity on the lower inner side of the top cover 1 and the upper part of the low-temperature filling component 6, create the required low-temperature filling environment for the low-temperature filling component 6. Then, introduce the raw material of the fish oil nutritional paste to be filled through the two sets of material pipes on the left rear side of the low-temperature filling component 6. At the same time, feed the filling bottle from the feed end in the middle position on the left side of the low-temperature filling component 6. Then, use the guide component 4 to fill and guide the bottle and paste. During the process, the limiting strips 3 on the front and rear sides of the upper end of the guide component 4 limit the position of the bottle, and the support leg 5 supports the bottom of the guide component 4. After filling is completed, the filled bottle is discharged from the discharge end 7 in the middle position on the right side of the low-temperature filling component 6, thus completing the entire filling operation process.

[0018] Please see Figures 1-4As a second embodiment of the present invention: based on the description in Embodiment 1, the low-temperature filling component 6 further includes an outer protective shell 61 and a temperature sensor bracket 601. The outer protective shell 61 has an outer insulation layer 62 on its inner side to prevent the cold air inside the delivery cavity 66 from dissipating. The outer insulation layer 62 has an inner pipe cavity 63 on its inner side for installing a low-temperature air circulation pipe 68. The right cross-section of the inner pipe cavity 63 is a U-shaped structure. The inner pipe cavity 63 has an annular low-temperature air circulation pipe 68 inside. The length of the low-temperature air circulation pipe 68 corresponds to the length of the front cross-section of the inner pipe cavity 63. The inner walls of the front and rear sides of the inner pipe cavity 63 are treated with moisture-proof and corrosion-proof measures. The inner side of the inner pipe cavity 63 is provided with an inner insulation layer 64 for providing insulation for the low temperature inside the guide cavity 66. The inner side of the inner insulation layer 64 is provided with an inner protective shell 65 for protecting the inner insulation layer 64 from damage. The inner insulation layer 64 and the inner protective shell 65 are respectively provided with several sets of inner perforations for the cold air release pipe to pass through. The inner side of each inner perforation is provided with a sealing liner. The inner side of the low temperature air circulation pipe 68 is provided with several sets of cold air release pipes for introducing low temperature cold air into the guide cavity 66 at equal intervals. The cold air release pipe is sealed through the inner insulation layer 64 and the inner protective shell 65. The inside of the cold air release pipe is connected to the inside of the low temperature air circulation pipe 68 and the inside of the delivery cavity 66. A set of side limiters 69 is provided in the middle between every two sets of low temperature cold air delivery pipes to limit their position. Each set of side limiters 69 has a set of temperature sensor brackets 601 at the upper end to detect the temperature of the cold air release pipe. Each set of temperature sensor brackets 601 has a set of temperature sensors inside.

[0019] The guide cavity 66 includes a filling component 6a, a capping component 6b, a labeling component 6c, a limiting component 6d, and a motor housing 6e. The filling component 6a is located inside the left side of the guide cavity 66. On the right side of the guide cavity 66, there is a set of labeling components 6c for hot stamping trademarks on the outside of the filling bottle. On the right side of the labeling component 6c, there is a set of capping components 6b for sealing the opening of the filling bottle. In front of the capping component 6b and the labeling component 6c, there is a set of limiting components 6d for guiding and limiting the flow of several groups of filling bottles. At the lower end of the limiting component 6d, there is a set of motor housing 6e for providing rotational power. Inside the motor housing 6e, there is a set of drive motors. In actual use, the low-temperature filling component 6 and the internal components of the guide cavity 66 work together to have many beneficial effects. The outer insulation layer 62 on the inner side of the outer protective shell 61 and the inner insulation layer 64 on the inner side of the inner pipe cavity 63 constitute a double insulation design, which can effectively prevent the cold air inside the guide cavity 66 from dissipating. The annular low-temperature air circulation pipe 68 inside the inner pipeline cavity 63 can evenly deliver low-temperature cold air. The two work together to ensure that the delivery cavity 66 always maintains a stable low-temperature filling environment, avoiding problems such as layering and abnormal viscosity of fish oil nutritional paste due to temperature fluctuations, thus ensuring the quality of the paste. The temperature sensor inside the temperature sensor bracket 601 can monitor the release temperature of the cold air release pipe in real time, which facilitates timely adjustment of the refrigeration state and improves the accuracy of low-temperature environment control. The side limit bracket 69 can fix the position of the cold air release pipe. The inner insulation layer 64 and the inner protective shell 65 have internal perforations and inner side sealing lining to prevent cold air leakage. The two work together to avoid cold air waste and ensure the stable operation of the cold air release pipe, reducing the risk of equipment failure. The filling component 6a on the left side of the guide cavity 66 can complete the filling of fish oil nutritional paste. The labeling component 6c on the right side of the guide cavity 66 can realize the hot stamping of the trademark on the outside of the bottle. The capping component 6b on the right side of the labeling component 6c can complete the sealing of the cap at the bottle opening. The limiting component 6d can limit and guide multiple groups of bottles in the process. The drive motor inside the motor box 6e can provide stable power to the limiting component 6d. The two work together to ensure that the bottle moves in an orderly manner in the guide cavity 66 and avoid the bottle from deviating.

[0020] Please see Figures 1-6 As a third embodiment of the present invention: based on the description in Embodiments 1 and 2, the filling component 6a further includes an inner frame a1 and a mixing tube a15. The inner frame a1 is a rectangular structure. There are two sets of inner frames a1. The rear inner frame a1 is a fixed structure and the front inner frame a1 is a movable structure. Each set of inner frames a1 has a clamping frame a10 for positioning the bottle to be filled at its lower end. Two sets of clamping frames a10 are arranged symmetrically. Several sets of positioning filling grooves are opened on the inner side of the clamping frame a10 for positioning and fitting the upper end of the filling bottle. The positioning filling grooves are arc-shaped. When the distance between the two sets of clamping frames a10 and the inner frame a1 is shortened, the two sets of positioning filling grooves form an elliptical overall filling groove. A set of clamping electric cylinder a2 is provided on the left inner side of the two sets of inner frames a1 for adjusting the distance between them. A set of clamping electric cylinder a2 is provided on the right inner side of the two sets of inner frames a1 for adjusting the distance between them. The clamping electric cylinder a2 and the clamping electric cylinder a2 have the same structure and move synchronously. Clamping cylinder a2 and clamping cylinder a2 are connected and fixed to the front inner frame a1 by bolts. The driving ends of clamping cylinder a2 and clamping cylinder a2 are both located on the rear side and are connected and fixed to the rear inner frame a1 by bolts. Several sets of filling heads a8 for filling fish oil nutritional paste are provided in the middle position between the two sets of inner frames a1. The number of filling heads a8 corresponds to the number of filling tanks in the whole. Each set of filling heads a8 has a filling column a7 at the top for guiding and supplying fish oil nutritional paste. The filling column a7 has a control valve for controlling the filling amount and an inner cavity for storing fish oil nutritional paste raw materials. The filling column a7 has a buffer spring a6 at the top for supporting the reverse force when the bottle is in contact with the top. The lower end of the buffer spring a6 has an inner locking groove at the contact position with the filling column a7. Several sets of buffer springs a6 are provided with an upper fixed frame a4 for supporting their top. Each set of filling columns a7 is provided with a conveying pipe a5 for conveying the raw materials of fish oil nutritional paste. The conveying pipe a5 is connected to the inner cavity. A set of fixing nuts is provided on the outer side of the lower end of the conveying pipe a5 for fixing its position. The fixing nuts are connected to the outer side of the lower end of the conveying pipe a5 by thread until the bottom of the fixing nut is in contact with the upper surface of the upper fixed frame a4. A set of lifting electric cylinders a11 is provided on the upper left side of the upper fixed frame a4 for controlling the height of the upper fixed frame a4.

A mixing pipe a14 is provided on the upper end of mixing pipe a15 to transport the raw materials of fish oil nutritional paste. Mixing pipes a14 and a15 are connected at right angles and a mixing tee is provided at the connection. In actual use, when the filling component 6a is working, the two sets of inner frames a1, which are fixed at the rear and movable at the front, are simultaneously connected at their left and right ends. The clamping electric cylinders a2 and a11, driven by the step movement, adjust their distance, causing the symmetrical clamping frame a10 at the lower end to move closer, so that the arc-shaped positioning filling grooves on the inner side of the clamping frame a10 are spliced ​​into an elliptical integral filling groove, thus achieving the positioning of the bottle. The mixing pipe a14 and the mixing pipe a15 connected at right angles inside the top beam a13 simultaneously introduce the fish oil nutritional paste raw materials and other mixed raw materials, and then transport them to the inner cavity of the filling column a7 through the conveying pipe a5. The control valve inside the filling column a7 regulates the filling volume, and the filling head a8 at the lower end fills the positioned bottle. The lifting electric cylinders a3 and a11, which operate synchronously on the left and right sides of the upper fixed frame a4, can adjust the height of the upper fixed frame a4. The buffer spring a6 at the upper end of the filling column a7 provides a reverse force support when the bottle contacts, ensuring a stable and accurate filling process.

[0021] Please see Figures 1-4 as well as Figure 8 As a fourth embodiment of the present invention: based on the description in embodiments one and two, the capping component further includes a capping motor b1 and a capping screw head b12. The lower end of the capping motor b1 is provided with a set of support bases b2 for supporting its bottom. The lower end of the support bases b2 is provided with a set of movable seat plates b5 for connecting to the support bases b2 and driving the support bases b2 to move up and down. The upper front end of the movable seat plates b5 is fixed to the support bases b2 by bolts. The right side of the movable seat plate b5 is considered to be an L-shaped structure. The right side of the movable seat plate b5 is provided with two sets of movable inserts for guiding its up and down movement. The movable inserts are fixed to the movable seat plate b5 by bolts. The right side of the movable insert is provided with a set of guide rails b7, which are movably fitted and connected to the movable inserts.

The upper front end of the movable seat plate b5 is fixed with a support frame b2 by bolts. The support frame b2 supports the capping motor b1. The lower end of the capping motor b1 is connected to the connecting end b11 via a telescopic universal joint. The buffer spring b10 on the outside of the telescopic universal joint can buffer the reverse force during capping. The cap tightening head b12 installed at the lower end of the connecting end b11 is positioned and fitted with the cap body at the upper end of the bottle through the inner cap groove. The capping motor b1 drives the cap tightening head b12 to rotate and complete the capping. In the whole process, all components work together to achieve accurate positioning and stable capping of the bottle and cap. The buffer structure can avoid damage to the cap or bottle, and the guiding structure ensures the accuracy of operation, ultimately achieving a high-efficiency and high-quality capping effect and ensuring that the product's sealing performance meets the standards.

[0022] Please see Figures 1-4 as well as Figure 8 As the fifth embodiment of the present invention: based on the description in embodiments one and two, further, the limiting member 6d includes a card head plate d1 and a synchronous connecting column d14. The card head plate d1 has a circular cross-section when viewed from above. The outer side of the card head plate d1 is uniformly provided with a number of card head grooves d5 for mutually limiting and fitting with the outer side of the bottle body. The number of card head grooves d5 are arranged in a ring structure. The cross-section of the number of card head grooves d5 when viewed from above is an arc-shaped semi-circular structure. Each set of card slots d5 has a set of reinforcing liner plates d2 on the outer side of the upper end to strengthen the outer strength of the card slots d5. The reinforcing liner plates d2 are fixed to the card plate d1 by bolts. The upper end of the middle position of the card plate d1 has a set of fixing flanges d4 to provide transmission effect. The fixing flanges d4 are fixed to the card plate d1 by several sets of bolts. The middle position of the fixing flanges d4 has a set of core rods d3 to transmit the power inside the motor box 6e. The core rods d3 pass through the fixing flanges d4 and are fixed to them. Several sets of synchronous connecting posts d14 are evenly distributed at the lower end of the card head plate d1 for connecting and fixing with the bottle card plate d6. At the lower end of the several sets of synchronous connecting posts d14, there is a set of bottle card plates d6 for rotating and guiding the filling bottle. Several sets of bottle card slots d7 are evenly distributed on the outer side of the bottle card plate d6 for providing fitting and positioning on the outer side of the filling bottle. The number of bottle card slots d7 is the same as the number of card head slots d5. The inner diameter of the bottle card slot d7 in the top view cross section is greater than the inner diameter of the card head slot d5 in the top view cross section.

[0023] The lower end of the bottle-holding disc 1 d6 is provided with several sets of synchronous connecting posts 1 d8 for connecting and fixing it to the bottle-holding disc 2. The lower end of the several sets of synchronous connecting posts 1 d8 is provided with a bottle-holding disc 2 for driving the outer side of the bottom of the filling bottle to rotate. The bottle-holding disc 1 d6 and the bottle-holding disc 2 have the same specifications, and the bottle-holding disc 2 has several sets of bottle-holding grooves 2 evenly arranged inside. The bottle-holding groove 1 d7 has the same specifications as the bottle-holding groove 2 and is completely overlapped in the vertical direction. The center position of both the bottle-holding disc 1 d6 and the bottle-holding disc 2 is provided with a rod groove d9 for the core rod d3 to pass through. The lower end of the core rod d3 is provided with a driven gear d10 for power transmission. The middle position of the driven gear d10 is connected and fixed to the outer side of the lower end of the core rod d3. A set of driving gears d11 for power connection is provided on the front side of the driven gear d10. The driving gears d11 and driven gears d10 mesh with each other. A set of drive rods d12 for power transmission is provided at the lower end of the middle position of the driven gear d10. The lower end of the drive rods d12 passes through the interior of the motor housing 6e. The motor housing 6e contains a rotary motor for providing rotation of several sets of filling bottles. A set of universal joints is provided at the connection between the driven gear d10 and the drive rods d12. A set of base plates for supporting the universal joints is provided on the outer side of the lower end of the universal joints. The lower end of the base plate is equipped with four sets of stable support frames for stable support. In actual use, the rotary motor in the motor box 6e drives the driven gear d10 through the drive rod d12 and universal joint. After meshing with the driving gear d11, the force is efficiently transmitted through the core rod d3. With the synchronous rotation structure formed by the clamping head plate d1, the bottle clamping plate one d6, and the bottle clamping plate two through the synchronous connecting column one d8, it can ensure that the rotation speed of multiple components is consistent, avoid the positional deviation caused by the speed deviation during the bottle conveying process, and provide a stable bottle conveying state for subsequent processes. In terms of positioning and limiting, the arc-shaped semi-circular groove d5 on the outer side of the clamping head plate d1 vertically overlaps with the grooves d7 and d8 on the bottle clamping plates d6 and d7, respectively. The inner diameter of the bottle clamping groove is adapted to the bottom of the bottle, and the clamping head groove d5 is adapted to the upper middle part of the bottle, thus achieving dual positioning of the upper and lower ends of the bottle. At the same time, the reinforcing liner d2 on the outer side of the clamping head groove d5 increases the strength of the groove and prevents the groove from deforming after long-term use, which would affect the positioning accuracy. This effectively prevents the bottle from shaking or tilting during rotation and conveying. In terms of structural support, the base plate and four sets of stable support structures form a solid bottom support system, reducing vibration when components rotate and further improving overall operational stability. This not only reduces the risk of equipment failure but also ensures that each process can be precisely connected, ultimately improving production efficiency and product qualification rate, and meeting the needs of large-scale, high-precision production of anti-pet hair shedding fish oil nutritional paste.

[0024] A process for filling fish oil nutritional paste using a low-temperature filling device includes the following steps: S1: The temperature environment is controlled at 0-5℃. This temperature range needs to be maintained stably, with fluctuations not exceeding ±0.5℃. In the raw material pretreatment stage, the basic raw materials of fish oil nutritional paste and the auxiliary mixing raw materials are introduced into the internal cavity of the top beam through mixing pipe one and mixing pipe two, respectively. The raw materials need to be filtered through an 80-mesh filter in advance to remove impurities with a particle size greater than 0.18mm. After the cold air compressor starts, it continuously delivers cold air to the delivery chamber through the low-temperature air circulation pipe. The temperature sensor monitors the internal temperature of the delivery chamber in real time. When the temperature is higher than 5°C, the cold air compressor automatically increases its power, and when it is lower than 0°C, it reduces its output to ensure that the insulation layer between the inner pipe chamber and the delivery chamber plays its role and prevents the cold air from dissipating. At the same time, the support legs adjust their height through an electric telescopic rod to keep the overall horizontal error of the device within 0.3 mm / m, ensuring the subsequent filling accuracy. S2: The temperature environment is maintained at 0-5℃, consistent with the pretreatment stage, with no temperature fluctuation deviation. The filling bottle is introduced through the feeding end. After the limiting component is activated, the drive motor drives the active gear to rotate through the drive rod, which in turn meshes with the driven gear to make the core rod rotate. The carding plate and the upper and lower bottle carding plates rotate synchronously. The head slot, bottle slot one, and bottle slot two respectively fit and position the upper, middle, and bottom of the bottle body. The inner diameter of the bottle slot is 0.2-0.3mm larger than the outer diameter of the corresponding position on the bottle body to ensure a close fit without jamming. The limiting strips are fixed by connecting support rods. The three sets of limiting strips are distributed in a straight line. The uppermost strip is located at three-quarters of the height of the bottle body, limiting the left and right deviation of the bottle body during the conveying process to no more than 0.5mm. The bottle conveying speed is set to 10-15 bottles / minute to match the subsequent filling rhythm. S3: The temperature environment is maintained at 0-3℃. This temperature can prevent the fish oil nutritional paste from becoming abnormally fluid due to excessive temperature during the filling process. Clamping cylinder one and clamping cylinder two operate synchronously, driving the two sets of inner frames to move closer to each other. The positioning filling groove on the clamping frame surrounds the elliptical integral filling groove, which is precisely aligned with the upper opening of the bottle body. The alignment deviation does not exceed 0.2mm. Lifting cylinder one and lifting cylinder two drive the upper fixed frame to descend, and the filling head slowly extends into the bottle opening to a depth of one-third of the bottle height. The delivery pipe introduces the filtered raw material into the inner cavity of the filling column. The control valve adjusts the opening and closing degree according to the preset dosage. The filling volume error of a single bottle is controlled within ±0.5g. The buffer spring provides reverse support force when the filling head contacts the bottle body. The buffer stroke is 5-8mm to avoid the bottle body being damaged by pressure. S4: Maintain the temperature environment at 0-5℃ to ensure the finished product remains at a low temperature before discharge. The labeling component hot stamps the label onto the filled bottle, with the hot stamping temperature controlled at 40-50℃ and the stamping time at 2-3 seconds to avoid high temperature affecting the quality of the paste. During the capping stage, the adjusting electric cylinder drives the movable seat plate to descend along the guide rail, and the capping screw head is positioned and engaged with the cap at the top of the bottle. The capping motor drives the capping screw head to rotate through the telescopic universal joint at a speed of 30-40 revolutions per minute. The buffer spring buffers the reverse force during the capping process, ensuring that the tightening torque of the cap is between 0.8-1.2 N·m, preventing bottle damage caused by loosening or over-tightening. After capping, the bottle clamping plate continues to rotate, exporting the finished bottle through the discharge end. During the export process, the distance between the bottles is maintained at 5-8 cm to avoid collision and wear.

8. A process for filling fish oil nutritional paste using the low-temperature filling device according to any one of claims 1-7, characterized in that: Includes the following steps, S1: The temperature environment is controlled at 0-5℃. This temperature range needs to be maintained stably, with fluctuations not exceeding ±0.5℃. In the raw material pretreatment stage, the basic raw materials of fish oil nutritional paste and the auxiliary mixing raw materials are introduced into the internal cavity of the top beam through mixing pipe one and mixing pipe two, respectively. The raw materials need to be filtered through an 80-mesh filter in advance to remove impurities with a particle size greater than 0.18mm. After the cold air compressor starts, it continuously delivers cold air to the delivery chamber through the low-temperature air circulation pipe. The temperature sensor monitors the internal temperature of the delivery chamber in real time. When the temperature is higher than 5°C, the cold air compressor automatically increases its power, and when it is lower than 0°C, it reduces its output to ensure that the insulation layer between the inner pipe chamber and the delivery chamber plays its role and prevents the cold air from dissipating. At the same time, the support legs adjust their height through an electric telescopic rod to keep the overall horizontal error of the device within 0.3 mm / m, ensuring the subsequent filling accuracy. S2: The temperature environment is maintained at 0-5℃, consistent with the pretreatment stage, with no temperature fluctuation deviation. The filling bottle is introduced through the feeding end. After the limiting component is activated, the drive motor drives the active gear to rotate through the drive rod, which in turn meshes with the driven gear to make the core rod rotate. The carding plate and the upper and lower bottle carding plates rotate synchronously. The head slot, bottle slot one, and bottle slot two respectively fit and position the upper, middle, and bottom of the bottle body. The inner diameter of the bottle slot is 0.2-0.3mm larger than the outer diameter of the corresponding position on the bottle body to ensure a close fit without jamming. The limiting strips are fixed by connecting support rods. The three sets of limiting strips are distributed in a straight line. The uppermost strip is located at three-quarters of the height of the bottle body, limiting the left and right deviation of the bottle body during the conveying process to no more than 0.5mm. The bottle conveying speed is set to 10-15 bottles / minute to match the subsequent filling rhythm. S3: The temperature environment is maintained at 0-3℃. This temperature can prevent the fish oil nutritional paste from becoming abnormally fluid due to excessive temperature during the filling process. Clamping cylinder one and clamping cylinder two operate synchronously, driving the two sets of inner frames to move closer to each other. The positioning filling groove on the clamping frame surrounds the elliptical integral filling groove, which is precisely aligned with the upper opening of the bottle body. The alignment deviation does not exceed 0.2mm. Lifting cylinder one and lifting cylinder two drive the upper fixed frame to descend, and the filling head slowly extends into the bottle opening to a depth of one-third of the bottle height. The delivery pipe introduces the filtered raw material into the inner cavity of the filling column. The control valve adjusts the opening and closing degree according to the preset dosage. The filling volume error of a single bottle is controlled within ±0.5g. The buffer spring provides reverse support force when the filling head contacts the bottle body. The buffer stroke is 5-8mm to avoid the bottle body being damaged by pressure. S4: Maintain the temperature environment at 0-5℃ to ensure the finished product remains at a low temperature before discharge. The labeling component hot stamps the label onto the filled bottle, with the hot stamping temperature controlled at 40-50℃ and the stamping time at 2-3 seconds to avoid high temperature affecting the quality of the paste. During the capping stage, the adjusting electric cylinder drives the movable seat plate to descend along the guide rail, and the capping screw head is positioned and engaged with the cap at the top of the bottle. The capping motor drives the capping screw head to rotate through the telescopic universal joint at a speed of 30-40 revolutions per minute. The buffer spring buffers the reverse force during the capping process, ensuring that the tightening torque of the cap is between 0.8-1.2 N·m, preventing bottle damage caused by loosening or over-tightening. After capping, the bottle clamping plate continues to rotate, exporting the finished bottle through the discharge end. During the export process, the distance between the bottles is maintained at 5-8 cm to avoid collision and wear.
