Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, and specifically relates to a cam-driven konjac sol quantitative dispenser. Background Technology

[0002] Konjac sol holds a key position in many fields due to its unique gelling, thickening, and water-retaining properties. In food processing, it is used to improve the texture and stability of jellies and meat products; in cosmetics manufacturing, it can improve the texture of emulsions; and in pharmaceutical preparations, it can serve as an excellent binder and disintegrant.

[0003] Traditional gravity-flow distribution equipment relies on the gravity of the konjac sol itself for distribution. Once the viscosity of the sol changes, the flow rate becomes difficult to control. Mechanical extrusion equipment, while able to actively apply external force, suffers from significant fluctuations in the distribution volume due to the lack of a precise adjustment mechanism. Electronically controlled distribution equipment, while offering advantages in precision, suffers from complex structures and high costs due to the configuration of sophisticated sensors and circuits, and is subject to stringent requirements regarding cleanliness, temperature, and humidity. Pneumatic distribution equipment, while achieving good distribution results, requires a large air supply and control system, occupying significant space and incurring high procurement, maintenance, and operating costs. These technological shortcomings severely restrict the efficient development of the konjac sol industry. In other words, existing technologies suffer from low distribution precision, unstable distribution volumes, complex equipment structures, and high costs. Utility Model Content

[0004] In view of this, the present invention provides a cam-driven konjac sol quantitative dispenser, which can solve the technical problems of low dispensing accuracy, unstable dispensing volume, complex equipment structure, and high cost of konjac sol.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a cam-driven konjac sol quantitative dispenser, including a base, a cam drive mechanism mounted on the base, a dispensing pump body that is drively connected to the cam drive mechanism, a piston assembly mounted in the dispensing pump body, and a dispensing nozzle connected to the outlet end of the dispensing pump body. The cam drive mechanism includes a cam wheel and a push rod that contacts the contour surface of the cam wheel. The other end of the push rod is connected to the piston assembly. The rotation of the cam wheel drives the push rod to reciprocate, thereby realizing the quantitative dispensing of konjac sol.

[0007] The technical advantages of the cam-driven konjac sol metering dispenser provided by this utility model are as follows: the cam-driven mechanism converts the rotary motion into linear reciprocating motion, driving the piston assembly to reciprocate within the dispensing pump body, thereby realizing the intake and discharge of konjac sol and ensuring the accuracy and continuity of the dispensing.

[0008] Based on the above technical solution, the cam-driven konjac sol metering dispenser of this utility model can be further improved as follows:

[0009] The cam wheel has multiple protrusions and recesses on its contour surface, with the protrusions and recesses alternating. The radial height of the protrusions is greater than that of the recesses.

[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the alternating distribution of the convex and concave parts of the cam wheel disk enables the push rod to produce regular reciprocating motion. The convex part pushes the push rod forward, and the concave part allows the push rod to retract, ensuring the periodicity and stability of the distribution action.

[0011] Furthermore, a roller is provided at the end of the push rod, and the roller makes rolling contact with the contour surface of the cam wheel. The roller is mounted at the end of the push rod via a bearing.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the roller at the end of the push rod makes rolling contact with the cam wheel, reducing frictional resistance and improving transmission efficiency; the bearing installation method ensures that the roller rotates flexibly, extends service life, and reduces maintenance requirements.

[0013] Furthermore, the piston assembly includes a piston rod and a piston head mounted at the end of the piston rod, the piston head forming a sealed chamber within the dispensing pump body.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the piston assembly, through the cooperation of the piston rod and the piston head, forms a variable-volume sealed chamber in the dispensing pump body, realizing the precise intake and discharge of konjac sol and ensuring accurate control of the dispensing amount.

[0015] Furthermore, the distribution pump body is equipped with an inlet and an outlet. The inlet is connected to the konjac sol storage tank, and the outlet is connected to the distribution nozzle.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the inlet and outlet of the distribution pump are connected to the storage tank and the distribution nozzle respectively, forming a complete konjac sol flow path, ensuring that the material can be smoothly transported from the storage container to the distribution point.

[0017] Furthermore, the feed inlet is equipped with a one-way valve, which allows konjac sol to flow from the storage tank into the distribution pump body and prevents konjac sol from flowing back.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the one-way valve at the feed inlet prevents konjac sol from flowing back during the distribution process, ensures the singleness of the distribution direction, improves the distribution accuracy, and avoids material waste and distribution errors.

[0019] Furthermore, the dispensing nozzle is equipped with an adjusting nut, which is used to adjust the size of the discharge orifice of the dispensing nozzle.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the adjusting nut of the dispensing nozzle can adjust the size of the discharge orifice to adapt to konjac sol of different viscosities and different dispensing requirements, thereby improving the applicability and dispensing accuracy of the equipment.

[0021] Furthermore, the cam drive mechanism also includes a transmission gear set, which is coaxially connected to the cam wheel.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the transmission gear set provides a speed reduction and torque increase function, so that the cam wheel can obtain a suitable speed and torque, ensuring that the distribution action is smooth and powerful, and adapting to the viscous characteristics of konjac sol.

[0023] Furthermore, the base is provided with a guide groove, and the push rod makes a linear reciprocating motion within the guide groove.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the guide groove on the base restricts the push rod to only perform linear reciprocating motion, preventing the push rod from deviating or swaying during the movement, and ensuring the accuracy and stability of the piston assembly movement.

[0025] Furthermore, a sealing ring is provided between the piston head and the inner wall of the distribution pump body, and the sealing ring is made of corrosion-resistant rubber material.

[0026] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the sealing ring between the piston head and the inner wall of the distribution pump body ensures the sealing performance of the sealing chamber, preventing konjac sol leakage; and the corrosion-resistant rubber material adapts to the chemical properties of konjac sol.

[0027] Compared with existing technologies, the advantages of the cam-driven konjac sol quantitative dispenser provided by this utility model are as follows: The cam-driven mechanism precisely converts rotary motion into linear reciprocating motion, which, in conjunction with the piston assembly and dispensing pump, achieves precise quantitative dispensing of konjac sol, solving the technical problems of low dispensing accuracy and unstable dispensing volume in existing technologies. The special contour design of the cam wheel causes the push rod to produce regular reciprocating motion, ensuring consistency in the dispensing volume each time. The one-way valve prevents backflow and improves dispensing accuracy. The design of the adjusting nut enhances the applicability of the equipment, allowing it to adapt to konjac sol of different viscosities. The overall structure is simple and reliable, easy to maintain, and reduces equipment costs and ease of use. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] like Figure 1Figure 2 shows a cam-driven konjac sol dispensing device provided by this utility model, comprising a base 1, a cam drive mechanism 2 mounted on the base 1, a dispensing pump body 6 connected to the cam drive mechanism 2, a piston assembly 7 installed in the dispensing pump body 6, and a dispensing nozzle 10 connected to the outlet end of the dispensing pump body 6. The cam drive mechanism 2 includes a cam wheel 3 and a push rod 4 in contact with the contour surface of the cam wheel 3, the other end of which is connected to the piston assembly 7. The contour surface of the cam wheel 3 has multiple protrusions 19 and recesses 20, which are alternately distributed. The radial height of the protrusions 19 is greater than the radial height of the recesses 20, forming a periodic contour change. The end of the push rod 4 is provided with a roller 5, which is mounted on the end of the push rod 4 through a bearing 18, forming a rolling contact with the contour surface of the cam wheel 3 to reduce frictional resistance. The piston assembly 7 includes a piston rod 8 and a piston head 9 installed at the end of the piston rod 8, the piston head 9 forming a variable-volume sealed chamber in the dispensing pump body 6. The distribution pump body 6 has an inlet 11 and an outlet 12. The inlet 11 is connected to the konjac sol storage tank 21 via a connecting flange 24, and the outlet 12 is connected to the distribution nozzle 10. The inlet 11 is equipped with a one-way valve 13, which allows konjac sol to flow from the storage tank 21 into the distribution pump body 6 and prevents backflow of konjac sol. The distribution nozzle 10 is equipped with an adjusting nut 14, which is used to adjust the size of the outlet hole 22 of the distribution nozzle 10. The cam drive mechanism 2 also includes a transmission gear set 15, which is coaxially connected to the cam wheel 3 to provide a speed reduction and torque increase function. The base 1 is provided with a guide groove 16, and the push rod 4 makes linear reciprocating motion within the guide groove 16. The guide groove 16 restricts the direction of movement of the push rod 4. A sealing ring 17 is provided between the piston head 9 and the inner wall of the distribution pump body 6. The sealing ring 17 is made of corrosion-resistant rubber material to ensure the sealing of the sealed chamber. A spring 23 is provided between the push rod 4 and the piston rod 8, and the spring 23 provides the restoring force for the push rod 4 during its return stroke.

[0035] The production and usage process of this solution is as follows: First, the konjac sol storage tank 21 is connected to the inlet 11 of the distribution pump body 6 via the connecting flange 24. The transmission gear set 15 is started to drive the cam wheel 3 to rotate. When the protrusion 19 of the cam wheel 3 contacts the roller 5 at the end of the push rod 4, the push rod 4 moves forward in the guide groove 16, and the piston assembly 7 moves forward accordingly. The piston head 9 compresses the sealed chamber in the distribution pump body 6, and the konjac sol is squeezed out through the outlet 12 and the outlet hole 22 of the distribution nozzle 10. When the cam wheel 3 continues to rotate to the recessed position 20, the push rod 4 retracts under the action of the spring 23, the piston assembly 7 moves backward, the volume of the sealed chamber increases, generating negative pressure, and the konjac sol is sucked into the distribution pump body 6 from the storage tank 21 through the one-way valve 13. The size of the outlet hole 22 can be adjusted by adjusting the nut 14 to adapt to different viscosities of konjac sol and different distribution requirements. Operators can adjust the distribution frequency by controlling the rotational speed of the transmission gear set 15 to achieve different distribution rhythms.

[0036] Building upon the above, by doubling the number of protrusions 19 and recesses 20 on the cam disc 3, a denser contour variation is created, enabling higher-frequency distribution actions. Simultaneously, the push rod 4 is designed as a double-push rod structure, with push rods 4 positioned on both sides of the cam disc 3. The two push rods 4 are connected to the same piston assembly 7 via connecting rods, forming a symmetrical drive. The distribution pump body 6 adopts a dual-chamber design, with two independent sealed chambers, each equipped with an independent piston head 9. The inlet 11 and outlet 12 of the two chambers are connected separately, achieving parallel dual-path distribution. The distribution nozzle 10 adopts a multi-hole design, with multiple outlet holes 22, each equipped with an independent adjusting nut 14, enabling simultaneous multi-point distribution or distribution requirements of different specifications. The transmission gear set 15 adopts a planetary gear structure, providing a larger reduction ratio and smoother transmission characteristics.

[0037] The improved production process is as follows: the double pusher structure generates symmetrical propulsion force when the cam wheel 3 rotates, eliminating the offset and vibration that may be caused by unilateral force and improving the smoothness of movement. The dual-chamber design allows the two sealed chambers to work alternately; when one chamber is in the discharge state, the other chamber is in the suction state, realizing a continuous and uninterrupted distribution process. The multi-hole distribution nozzle 10 can simultaneously distribute konjac sol to multiple positions, or adjust the opening of different discharge holes 22 as needed to achieve different combinations of distribution amounts. The planetary gear transmission gear set 15 provides higher transmission accuracy and lower noise levels, while also having a stronger load-bearing capacity, suitable for long-term continuous operation. Operators can select single-chamber or dual-chamber working modes according to production needs, flexibly adapting to different production requirements.

[0038] The improved design surpasses the basic design by doubling the distribution frequency, significantly increasing production efficiency. The dual-pushrod symmetrical drive eliminates motion deviation, further enhancing distribution accuracy. Compared to existing technologies, the technical advantages include: parallel operation of the dual chambers enables continuous distribution, eliminating the intermittent distribution defects of traditional single-chamber equipment and greatly improving production continuity and efficiency; the symmetrical drive structure significantly reduces equipment vibration and noise, improving the comfort of the working environment; the multi-hole distribution design meets the needs of simultaneous or combined distribution at multiple points, enhancing the equipment's process adaptability; and the planetary gear transmission system provides higher transmission accuracy and load-bearing capacity, ensuring the stability and reliability of the equipment under high-intensity working conditions. The overall design maintains the simplicity and reliability of mechanical transmission, avoiding the cost and maintenance problems of complex control systems, achieving a harmonious balance of high efficiency, high precision, and low cost.

[0039] Specifically, the principle of this invention is as follows: the cam drive mechanism, through the rotation of the cam wheel, utilizes the geometric characteristics of the cam profile to convert continuous rotary motion into intermittent linear reciprocating motion of the push rod. When the cam wheel rotates, the protrusion pushes the push rod forward, the piston assembly moves forward, the volume of the sealed chamber inside the distribution pump body decreases, and the konjac sol is squeezed out through the outlet and distribution nozzle. When the cam wheel continues to rotate to the recessed position, the push rod retracts under the action of spring force or gravity, the piston assembly moves backward, the volume of the sealed chamber increases, generating negative pressure, and the konjac sol is drawn into the chamber through the one-way valve at the inlet. By controlling the rotational speed of the cam wheel and the design of the cam profile, the distribution time interval and distribution amount can be precisely controlled. The rolling contact between the roller and the cam wheel reduces friction loss, improving transmission efficiency and equipment life. The guide groove design ensures the linearity of the push rod movement, avoiding distribution errors caused by motion deviations.

[0040] The following are two embodiments based on specific implementation methods;

Example 2

[0045] Example 2:

[0046] Based on the improved implementation scheme, a structure configuration of double push rods 4, a dual-chamber distribution pump body 6, and a multi-hole distribution nozzle 10 is adopted. The base 1 is made of ductile iron, with dimensions of 600×400×100 mm, and the surface of the base 1 is galvanized for corrosion protection. The cam wheel 3 is made of 40Cr steel with a diameter of 150 mm and a thickness of 35 mm. The contour surface has 16 protrusions 19 and 16 recesses 20. The radial height of the protrusions 19 is 20 mm, and the radial height of the recesses 20 is 10 mm. Two push rods 4 are symmetrically distributed on both sides of the cam wheel 3.

The rollers 5 at the ends of the push rods 4 have a diameter of 35 mm, and the bearings 18 are angular contact ball bearings of model 7007C. The pump body 6 features a dual-chamber design, with each chamber having an inner diameter of 55 mm and a length of 180 mm, and a chamber spacing of 120 mm. It is precision-machined from 316L stainless steel. Each chamber is equipped with an independent piston assembly 7, with a piston rod 8 measuring 220 mm in length and 22 mm in diameter, and a piston head 9 with a diameter of 53 mm.

Each chamber also has an independent one-way valve 13, with the valve body made of titanium alloy, exhibiting excellent corrosion resistance.

[0047] The dispensing nozzle 10 adopts a four-hole design, with four discharge holes 22 arranged in a square, each with a diameter of 2.5 mm. Each discharge hole 22 is equipped with an independent adjusting nut 14, allowing the diameter of the discharge hole 22 to be adjusted within the range of 1.5 to 5 mm.

The reduction ratio is 15:1, and the transmission efficiency reaches over 95%. The two push rods 4 are connected by a connecting rod made of aluminum alloy, which ensures transmission rigidity while reducing the weight of moving parts. The springs 23 are made of stainless steel spring steel, with two springs 23 for each push rod 4. Each spring 23 has a free length of 70 mm and provides a compressive force of 200 Newtons when compressed by 30 mm.

[0048] The assembly process of Example 2 is as follows: The planetary gear transmission system is installed in the center of the base 1, and the cam wheel 3 is fixed on the output shaft of the planetary gear.

The dispensing volume per time is 1.5 to 12 ml, and the dispensing accuracy can reach ±1.5%, which is 25% higher than that of Example 1. When dispensing from four holes simultaneously, the total dispensing volume can reach 9.6 liters per minute, meeting the needs of mass production. The symmetrical drive of the double push rods eliminates the vibration caused by unilateral force, and the equipment operating noise is reduced to below 58 decibels. The planetary gear transmission system has strong load-bearing capacity, smooth transmission, and a fault-free operating time of over 5000 hours. The multi-hole dispensing design can realize the simultaneous dispensing of konjac sol to four packaging containers by one machine, or the combined production of different specifications of products can be achieved by adjusting the opening of different discharge holes 22. Compared with the existing electronically controlled dispensing equipment, this example improves the production efficiency by 180% and reduces the equipment investment cost by 50% while maintaining the advantages of simple and reliable mechanical transmission, providing an efficient and economical automated dispensing solution for large-scale konjac sol production.
