Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and in particular to a water-based adhesive for standby quantitative feeding device. Background Technology

[0002] Recombinant collagen is widely used in tissue engineering scaffolds, drug delivery systems, cosmetic fillers, and wound dressings due to its excellent biocompatibility, biodegradability, and low immunogenicity. Hydrogels are one of its most common formulations. The key steps in preparing recombinant collagen hydrogels typically include: precisely mixing an aqueous solution of recombinant collagen with a thickener (such as carbomer), a pH adjuster (such as arginine), and a cross-linking agent to induce gelation. Currently, manual pipetting or simple peristaltic pumps are commonly used for feeding in laboratory and small-scale production.

[0003] However, in the aforementioned prior art, manual pipetting has large errors and low precision, which affects the subsequent preparation of hydrocolloids and increases costs. Summary of the Invention

[0004] The purpose of this invention is to provide a quantitative feeding device for preparing hydrocolloids, which aims to solve the problems of large errors and low precision in manual pipetting in the prior art, which affect the subsequent preparation of hydrocolloids and increase costs.

[0005] To achieve the above objectives, the present invention provides a water-based adhesive pre-filled metering device, comprising a housing and a feeding connection assembly. The feeding connection assembly includes a temporary storage tank, a storage bin, a conveying pipe, a flow meter, a solenoid valve, a discharge pipe, a non-stick coating, a pushing component, a temperature control component, and a conveying component. The feeding connection assembly is connected to the housing. The temporary storage tank is disposed on the inner wall of the housing. The storage bin is fixedly connected to the housing and located on the inner wall of the housing. The conveying pipe communicates with the storage bin and is located below the storage bin. The flow meter communicates with the conveying pipe and is located in the middle of the conveying pipe. The solenoid valve communicates with the conveying pipe and is located at the lower end of the conveying pipe. The discharge pipe communicates with the temporary storage tank and is located on the outer wall of the temporary storage tank. The non-stick coating is fixedly connected to the discharge pipe and is located on the inner wall of the discharge pipe. The pushing component is connected to the temporary storage tank. The temperature control component is connected to the temporary storage tank. The conveying component is connected to both the storage bin and the housing.

[0006] The storage bin, the conveying pipe, the flow meter, and the solenoid valve are arranged in three arrays on the inner wall of the housing.

[0007] The pushing component includes a cylinder, a piston plate, and a sealing ring. The cylinder is installed on the outer side wall of the temporary storage bucket. The piston plate is slidably connected to the temporary storage bucket and located on the inner side wall of the temporary storage bucket. The piston plate has a groove that is adapted to the sealing ring. The sealing ring is installed on the inner side wall of the groove and contacts the temporary storage bucket.

[0008] The temperature control component includes a mounting base, an electric heating roller, and a temperature sensor. The mounting base is fixedly connected to the temporary storage tank and is located on the outer side wall of the temporary storage tank. The electric heating roller is fixedly connected to the mounting base and is located on one side of the mounting base. The temperature sensor is fixedly connected to the temporary storage tank and is located on the inner side wall of the temporary storage tank.

[0009] The temperature control component further includes a protective frame and a controller. The protective frame is fixedly connected to the temporary storage tank and located on the inner side wall of the temporary storage tank. The controller is fixedly connected to the housing and located on the outer side wall of the housing. The controller is electrically connected to the solenoid valve, the flow meter, the cylinder, the heating roller, and the temperature sensor, respectively.

[0010] The material conveying component includes a pump body, a raw material tank, a connecting pipe, a sealing ring, and a lifting component. The pump body is connected to the storage silo and located above the storage silo. The raw material tank is disposed on one side of the housing. The lifting component is connected to both the housing and the raw material tank. The connecting pipe is connected to the pump body and located at the input end of the pump body, with its end inserted into the raw material tank. The sealing ring is fixedly connected to the connecting pipe and located on the outer wall of the connecting pipe, and the sealing ring is in contact with the raw material tank.

[0011] The lifting component includes a side plate, an electric telescopic rod, and a lifting platform. The side plate is fixedly connected to the housing and located on one side of the housing. The electric telescopic rod is installed below the side plate. The lifting platform is fixedly connected to the electric telescopic rod and located at the output end of the electric telescopic rod. The lifting platform is in contact with the raw material tank. The output end of the electric telescopic rod passes through the side plate.

[0012] This invention discloses a water-based adhesive for standby quantitative feeding device. First, the conveying component begins operation, extracting and transporting external raw materials to the storage hopper for temporary storage. When quantitative feeding is required, the solenoid valve on the conveying pipe at the lower end of the storage hopper opens, allowing the raw materials to flow through the conveying pipe to the temporary storage hopper under gravity or pressure. During this process, the flow meter monitors and provides real-time feedback on the flow rate or cumulative volume of the raw materials flowing through the conveying pipe to achieve precise measurement and control of the feeding amount. After the raw materials enter the temporary storage hopper, the temperature control component immediately activates, rapidly and accurately adjusting the temperature of the raw materials inside the hopper to ensure their physicochemical stability. When it is necessary to discharge the raw materials to downstream processes... In the initial stage, the pushing component is activated, smoothly pushing the raw material in the temporary storage tank at a controllable rate. The raw material then flows out through the discharge pipe, whose inner wall is coated with the non-stick coating, thus completing a high-precision raw material addition operation. The entire process is automatically coordinated by the control system to operate the conveying component, the solenoid valve, the flow meter, the temperature control component, and the pushing component, realizing fully enclosed and automated quantitative addition. In this way, the problems of large errors and poor reproducibility in manual pipetting in the prior art are fundamentally solved. Its high-precision control effectively ensures the uniformity of the formulation and the stability of product performance in the subsequent hydrocolloid preparation, and ultimately reduces the cost caused by raw material waste and batch non-compliance.

[0021] This invention provides a water-based adhesive pre-filling metering device, comprising a housing 101 and a feeding connection assembly. The feeding connection assembly includes a temporary storage tank 102, a storage bin 103, a conveying pipe 104, a flow meter 105, a solenoid valve 106, a discharge pipe 107, a non-stick coating 108, a pushing component, a temperature control component, and a conveying component. The pushing component includes a cylinder 109, a piston plate 110, and a sealing ring 111. The temperature control component includes a mounting base 112, an electric heating roller 113, a temperature sensor 114, a protective frame 115, and a controller 116. The conveying component includes a pump body 117, a raw material tank 118, a connecting pipe 119, a sealing ring 120, and a lifting component. The lifting component includes a side plate 121, an electric telescopic rod 122, and a lifting platform 123. The piston plate 110 has a groove 124. The water-based adhesive pre-filling metering device also includes a stabilizing component, which includes a mounting frame 125 and a connecting ring 126.

[0022] The feeding connection assembly is connected to the housing 101; the temporary storage tank 102 is disposed on the inner side wall of the housing 101; the storage bin 103 is fixedly connected to the housing 101 and located on the inner side wall of the housing 101; the conveying pipe 104 communicates with the storage bin 103 and is located below the storage bin 103; the flow meter 105 communicates with the conveying pipe 104 and is located in the middle of the conveying pipe 104; the solenoid valve 106 is connected to the conveying... Pipe 104 is connected and located at the lower end of the conveying pipe 104. The discharge pipe 107 is connected to the temporary storage tank 102 and located on the outer side wall of the temporary storage tank 102. The non-stick coating 108 is fixedly connected to the discharge pipe 107 and located on the inner side wall of the discharge pipe 107. The pushing component is connected to the temporary storage tank 102. The temperature control component is connected to the temporary storage tank 102. The conveying component is connected to the storage bin 103 and the shell 101 respectively.

[0023] In this embodiment, firstly, the conveying component starts working, extracting and conveying external raw materials to the storage bin 103 for temporary storage. When quantitative feeding is required, the solenoid valve 106 on the conveying pipe 104 at the lower end of the storage bin 103 opens, and the raw materials flow through the conveying pipe 104 to the temporary storage tank 102 under gravity or pressure. During this process, the flow meter 105 monitors and provides feedback on the flow rate or cumulative volume of the raw materials flowing through the conveying pipe 104 in real time to achieve precise measurement and control of the feeding amount. After the raw materials enter the temporary storage tank 102, the temperature control component immediately starts, rapidly and accurately adjusting the temperature of the raw materials inside the temporary storage tank 102 to ensure their physicochemical properties remain stable. When it is necessary to discharge the raw materials to the next storage tank, the temperature control component is activated. During the feeding process, the feeding component is activated to smoothly push the raw material out of the temporary storage tank 102 at a controllable rate. The raw material then flows out through the discharge pipe 107, which is coated with the non-stick coating 108 on its inner wall, thus completing a high-precision raw material addition operation. The entire process is automatically coordinated by the control system to operate the feeding component, the solenoid valve 106, the flow meter 105, the temperature control component, and the feeding component, realizing fully enclosed and automated quantitative addition. In this way, the problems of large errors and poor reproducibility of manual pipetting in the prior art are fundamentally solved. Its high-precision control effectively ensures the uniformity of the formulation and the stability of product performance in the subsequent hydrocolloid preparation, and ultimately reduces the cost caused by raw material waste and batch non-conformity.

[0024] Furthermore, the storage bin 103, the conveying pipe 104, the flow meter 105, and the solenoid valve 106 are arranged in three arrays on the inner side wall of the housing 101.

[0025] In this embodiment, the storage bin 103, the delivery pipe 104, the flow meter 105, and the solenoid valve 106 are arranged in an array on the inner side wall of the housing 101, which facilitates the addition of recombinant collagen aqueous solution, thickener (such as carbomer), pH adjuster (such as arginine), and crosslinking agent by the operator.

[0026] Furthermore, the cylinder 109 is installed on the outer side wall of the temporary storage bucket 102, the piston plate 110 is slidably connected to the temporary storage bucket 102 and located on the inner side wall of the temporary storage bucket 102, the piston plate 110 has a groove 124, the groove 124 is adapted to the sealing ring 111, the sealing ring 111 is installed on the inner side wall of the groove 124 and contacts the temporary storage bucket 102.

[0027] In this embodiment, when the control system issues a discharge command, the piston rod of the cylinder 109 begins to move linearly, driving the piston plate 110 to slide smoothly along the inner wall of the temporary storage tank 102. Since the sealing ring 111 is installed in the groove 124 of the piston plate 110, the sealing ring 111 maintains close contact with the inner wall of the temporary storage tank 102, forming a dynamic and reliable sealing interface. This sealing interface effectively prevents the raw material from leaking from the gap between the piston plate 110 and the tank wall during the movement of the piston plate 110, ensuring that the driving force is fully applied to the raw material.

[0028] Furthermore, the mounting base 112 is fixedly connected to the temporary storage tank 102 and is located on the outer side wall of the temporary storage tank 102; the electric heating roller 113 is fixedly connected to the mounting base 112 and is located on one side of the mounting base 112; and the temperature sensor 114 is fixedly connected to the temporary storage tank 102 and is located on the inner side wall of the temporary storage tank 102.

[0029] In this embodiment, the temperature sensor 114 monitors the temperature of the raw materials inside the temporary storage tank 102 in real time and feeds the signal back to the control system. When the monitored temperature is lower than the set value, the control system starts the electric heating roller 113 to work, and the heat generated by it heats the raw materials inside the temporary storage tank 102 evenly through the wall. When the temperature reaches the set range, the control system adjusts or stops the power output of the electric heating roller 113, thereby achieving precise constant temperature control.

[0030] Furthermore, the protective frame 115 is fixedly connected to the temporary storage tank 102 and located on the inner side wall of the temporary storage tank 102, the controller 116 is fixedly connected to the housing 101 and located on the outer side wall of the housing 101, and the controller 116 is electrically connected to the solenoid valve 106, the flow meter 105, the cylinder 109, the electric heating roller 113 and the temperature sensor 114 respectively.

[0031] In this embodiment, the protective frame 115 is used to protect the temperature sensor 114, and the controller 116 is used for the electrical control of the entire device, making it convenient for staff to use.

[0032] Furthermore, the pump body 117 is connected to the storage bin 103 and is located above the storage bin 103. The raw material tank 118 is disposed on one side of the housing 101. The lifting component is connected to the housing 101 and the raw material tank 118 respectively. The connecting pipe 119 is connected to the pump body 117 and is located at the input end of the pump body 117. The end of the connecting pipe 119 is inserted into the raw material tank 118. The sealing ring 120 is fixedly connected to the connecting pipe 119 and is located on the outer side wall of the connecting pipe 119. The sealing ring 120 is in contact with the raw material tank 118.

[0033] In this embodiment, when raw materials need to be replenished to the storage bin 103, the lifting component is first activated, driving the raw material tank 118 to rise or move, so that its opening is aligned with and tightly engaged with the end of the connecting pipe 119. During this process, the end of the connecting pipe 119 is inserted into the interior of the raw material tank 118, and the sealing ring 120 on its outer wall forms a reliable static seal with the opening of the raw material tank 118, thereby establishing a closed transmission channel. Subsequently, the pump body 117 is activated, drawing the raw materials in the raw material tank 118 upward through the connecting pipe 119 and transporting them to the storage bin 103 for storage. By controlling the working time or rotation speed of the pump body 117, the amount drawn each time can be precisely controlled. After the material is conveyed, the lifting component drives the raw material tank 118 to descend, separating the connecting pipe 119 from it. This design realizes the automated and closed transfer of raw materials from the external container to the internal storage of the system, effectively avoiding pollution, volatilization or spillage that may be introduced by open operation, and ensuring the cleanliness, safety and quantitative control of the raw material transfer process.

[0034] Furthermore, the side plate 121 is fixedly connected to the housing 101 and located on one side of the housing 101. The electric telescopic rod 122 is installed below the side plate 121. The lifting platform 123 is fixedly connected to the electric telescopic rod 122 and located at the output end of the electric telescopic rod 122. The lifting platform 123 is in contact with the raw material tank 118. The output end of the electric telescopic rod 122 passes through the side plate 121.

[0035] In this embodiment, the side plate 121 is used to install the electric telescopic rod 122, which is used to drive the lifting platform 123 to move, so that the raw material tank 118 can be aligned with the connecting pipe 119.

[0036] Furthermore, the water-based quantitative feeding device also includes a stabilizing component, which includes a mounting frame 125 and a connecting ring 126. The mounting frame 125 is fixedly connected to the housing 101 and is located on one side of the housing 101. The connecting ring 126 is detachably connected to the mounting frame 125 and is located on one side of the mounting frame 125. The connecting ring 126 is adapted to the connecting pipe 119.

[0037] In this embodiment, the support structure formed by the mounting bracket 125 and the connecting ring 126 is used to improve the stability of the connecting pipe 119 and prevent the connecting pipe 119 from shaking when it is inserted into the raw material tank 118.
