Description

Technical Field

[0001] This utility model relates to the technical field of laundry detergent production equipment, and in particular to an automatic feeding device for laundry detergent production. Background Technology

[0002] In the production of laundry detergent, precisely controlling the amount of various raw materials added is crucial to ensuring product quality. Currently, there are two main methods for adding materials in laundry detergent production: manual addition and traditional automatic addition devices. Manual addition relies on the operator's experience and manual operation, which has many drawbacks. On the one hand, manual operation makes it difficult to guarantee the accuracy of each addition, easily leading to deviations in the amount of raw materials added, affecting the quality stability of the laundry detergent. On the other hand, manual addition is inefficient, labor-intensive, and prone to problems such as spillage and splashing of raw materials, resulting in waste and environmental pollution. While traditional automatic addition devices improve addition efficiency to some extent, they still have some problems. For example, some devices have complex structures and high costs, increasing the company's production investment; some devices lack effective coordination mechanisms when adding multiple materials simultaneously, easily leading to chaotic addition sequences and inaccurate addition amounts, failing to meet the high requirements of laundry detergent production for addition accuracy and efficiency.

[0003] Therefore, it is necessary to develop an automatic dispensing device for laundry detergent production to address the aforementioned shortcomings. Utility Model Content

[0024] In one specific implementation, such as Figures 1-5 As shown, an automatic feeding device for laundry detergent production includes a mixing chamber 1, with a stirring device extending into the top of the mixing chamber 1. The stirring device is used to mix and stir the raw materials and additives in the mixing chamber 1 evenly. Several storage tanks 2 are provided on one side of the mixing chamber 1, with at least three storage tanks 2 to meet the need for simultaneous addition of multiple raw materials. Five are preferred here. A transition chamber 3 is fixedly installed at the upper end of the mixing chamber 1 via a bracket, and the bottom of the transition chamber 3 is connected to the mixing chamber 1 via a pneumatic butterfly valve 4. The side wall of the mixing chamber 1 has an inlet 12, and the bottom has an outlet 13. A flow meter 6 for detecting the amount of raw materials entering is provided at the inlet 12, and both the inlet 12 and the outlet 13 are equipped with pneumatic ball valves 14 to control the material flow. The mixing chamber 1 serves as the site for the mixing and reaction of raw materials and additives. The mixing chamber 1 receives additives pushed in from the transition chamber 3 and raw materials entering through the inlet 12, achieving uniform mixing under the action of the stirring device. The pneumatic ball valves 14 at the feed inlet 12 and the discharge outlet 13 can flexibly control the entry and exit of raw materials, ensuring the continuity and stability of the production process.

[0025] In one specific implementation, such as Figures 1-5 As shown, each storage tank 2 is connected to the transition chamber 3 via an independent conveying pipeline 5. The pipeline 5 is equipped with a flow meter 6 and a conveying pump 7. Each pipeline 5 is fitted with a pneumatic shut-off valve 16, located near the inlet side of the transition chamber 3. The storage tanks 2 are used to store various additives required for laundry detergent production. Different storage tanks 2 can store different types of additives to meet production formula requirements. The independent conveying pipelines 5 connect to the transition chamber 3, facilitating the control of the addition amount and timing of different additives according to production needs.

[0026] In one specific implementation, such as Figures 1-5As shown, a first weighing sensor 8 is installed between the transition chamber 3 and the support frame to monitor the weight of the additive added to the transition chamber 3 in real time. The transition chamber 3 has a liftable conical pusher 9 inside, driven by a cylinder 10. The cylinder 10 is fixedly installed on the top of the transition chamber 3, and a vertical plate is provided on the top of the transition chamber 3, with the cylinder 10 fixed to the vertical plate. The lower end of the transition chamber 3 has a taper, and the lower end of the pusher 9 has a matching taper, forming a sealed fit between the lower end of the transition chamber 3 and the matching taper of the pusher 9. The transition chamber 3 serves as a material transfer station from the storage tank 2 to the mixing chamber 1, and its design makes the additive delivery more precise and controllable. The first weighing sensor 8 can accurately measure the weight of the material in the transition chamber 3, and combined with the flow meter 6 and the delivery pump 7 on the delivery pipeline 5, it can precisely control the amount of material added. The cylinder 10 pushes the pusher 9 to smoothly push the material in the transition chamber 3 into the mixing chamber 1, improving the efficiency and accuracy of material delivery.

[0027] In one specific implementation, such as Figures 1-5 As shown, the mixing chamber 1 is equipped with a rotary spray cleaning assembly 11. The rotary high-pressure nozzle 1102 can perform comprehensive cleaning of the interior of the mixing chamber 1, ensuring its cleanliness and hygiene and preventing cross-contamination between different batches of laundry detergent. The cleaning assembly 11 includes a water inlet pipe 1101, a rotary high-pressure nozzle 1102, a water inlet valve 1103, and a water meter 1104. The water inlet pipe 1101 is horizontally installed at the upper end of the mixing chamber 1, away from the feed inlet 12. The water inlet pipe 1101 passes through the side wall of the mixing chamber 1, and the rotary high-pressure nozzle 1102 is vertically installed at its front end. The water inlet pipe 1101 is equipped with a water inlet valve 1103, which is located on the outside of the mixing chamber 1. A water meter 1104 for measuring the amount of water entering the mixing chamber is located on the outside of the water inlet valve 1103. The rotary high-pressure nozzle 1102 can perform comprehensive cleaning of the interior of the mixing chamber 1, ensuring its cleanliness and hygiene and preventing cross-contamination between different batches of laundry detergent. The inlet valve 1103 and the water meter 1104 can precisely control the amount of cleaning water used, improving the cleaning effect while saving water resources.

[0028] In one specific implementation, such as Figures 1-5 As shown, a second weighing sensor 15 for calibrating the total weight of the raw materials in the mixing chamber 1 is provided at the lower end, forming a dual metering system with the first weighing sensor 8. The input amount of various additives is calculated based on the amount of raw materials in the mixing chamber 1, facilitating subsequent control of increasing the input amount of additives.

[0029] The operation process of this automatic feeding device for laundry detergent production is as follows: Based on the laundry detergent production formula, the pneumatic ball valve 14 is first opened to input the raw materials of the laundry detergent into the mixing chamber 1. The second weighing sensor 15 transmits the weight in the mixing chamber 1 to the controller. The type and quantity of additives to be added are determined based on the function of the laundry detergent to be processed. The pneumatic shut-off valve 16 on the corresponding storage tank 2's conveying pipeline 5 is opened, and the conveying pump 7 is started to convey the material from the storage tank 2 to the transition chamber 3. The flow meter 6 monitors the flow rate of the additives in real time, and the first weighing sensor 8 monitors the weight of the material in the transition chamber 3. When the additive reaches the set amount, the conveying pump 7 and the pneumatic shut-off valve 16 are closed. The cylinder 10 is started, pushing the pusher plug 9 down to push the material in the transition chamber 3 into the mixing chamber 1. The above steps are repeated to add the additives from other storage tanks 2 to the mixing chamber 1 in sequence. After all the required materials have been added to the mixing chamber 1, the stirring device is started to thoroughly mix the materials. After uniform mixing, the mixture is output through the outlet 13 at the lower end of the mixing chamber 1 for filling. After the material in mixing chamber 1 has been discharged, the cleaning component 11 inside mixing chamber 1 is opened. Rotating the high-pressure nozzle 1102 allows for comprehensive cleaning of the interior of mixing chamber 1, ensuring its cleanliness and hygiene and preventing cross-contamination between different batches of laundry detergent. The water inlet valve 1103 and water meter 1104 can precisely control the amount of cleaning water used, improving the cleaning effect while conserving water resources.
