Description

Technical Field

[0001] This utility model relates to the field of cream paper production technology, and more specifically, to a cream viscosity control device and system for cream paper production. Background Technology

[0002] Cream-coated paper, as a type of household paper, is increasingly favored by consumers due to its "softness" and "smoothness." During its production, cream is added to the base paper to make it softer. However, because the cream has a high viscosity and is greatly affected by temperature, current technologies often use heating of the storage tank or emulsion tank to maintain a certain temperature and fluidity of the cream in order to ensure more even coating. However, due to the large volume of the storage tank or emulsion tank and the large amount of cream, uneven heating of the cream is prone to occur. Furthermore, the temperature can easily drop during pipeline transportation. Since the cream is a mixture and its viscosity is significantly affected by temperature, this leads to fluctuations in coating amount and unstable product quality.

[0003] In view of this, the applicant has innovatively designed the cream viscosity control device and system for cream paper production, which aims to achieve automated control of cream viscosity through multi-stage heating and real-time monitoring, thereby ensuring stable coating amount. Utility Model Content

[0004] This invention provides a cream viscosity control device and system for cream paper production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cream viscosity control device for cream paper production includes a heat-insulating shell, a heating pipe is provided inside the shell, the inlet and outlet ends of the heating pipe extend through the heat-insulating shell to the outside of the heat-insulating shell, and a temperature sensor and a viscosity sensor are provided at the inlet and outlet ends of the heating pipe.

[0007] The heating pipe includes a metal pipe and a heating wire wound around the metal pipe.

[0008] The thermal insulation shell is equipped with a controller that is electrically connected to the heating wire, temperature sensor and viscosity sensor.

[0009] The thermal insulation shell is filled with thermal insulation material.

[0010] The thermal insulation shell includes an outer shell and an inner shell, with thermal insulation cotton sandwiched between the inner and outer shells.

[0011] A cream viscosity control system for cream paper production includes a storage tank, an emulsion tank, a coating device, and a vibrating screen connected in sequence via a liquid delivery pipeline. The discharge port of the vibrating screen is connected to the emulsion tank via a liquid delivery pipeline. The aforementioned cream viscosity control device is installed on the liquid delivery pipeline between the storage tank and the emulsion tank, the liquid delivery pipeline between the emulsion tank and the coating device, and the liquid delivery pipeline between the coating device and the vibrating screen.

[0012] The infusion pipeline is covered with an insulation layer.

[0013] This utility model discloses a cream viscosity control device for cream paper production. By arranging heating pipes inside an insulated housing, a heat-insulated heating space is formed, improving heating efficiency. Temperature and viscosity sensors are installed at both the inlet and outlet of the heating pipes to monitor and control the temperature and viscosity of the cream entering and exiting the device in real time. This allows for automatic adjustment of the heating power of the electric heating wire, stabilizing the cream viscosity within a preset range. Combined with dynamic adjustment of the heating power using the insulation filler, the device avoids excessively high or low heating temperatures, ensuring a stable cream viscosity.

[0014] During the material feeding process of the coating equipment, the control system utilizes two control devices to achieve two-stage heating of the cream, improving the viscosity stability of the cream during coating. During the material recovery process, the control devices further adjust the temperature and viscosity to compensate for heat loss during coating, increasing the cream's recycling rate and reducing waste.

[0015] This invention features high precision in controlling cream viscosity, uniform coating amount, and stable product quality; improved heating efficiency and reduced energy consumption; and a high degree of system automation, reducing manual intervention. It is characterized by simple structure, low cost, strong practicality, and good performance, and is worthy of widespread promotion and use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] See Figure 1 and 2A cream viscosity control system for cream paper production includes a liquid delivery pipe 5 with an insulation layer.

[0020] The system consists of a storage tank 1, an emulsion tank 2, a coating device 3, and a vibrating screen 4 connected in sequence. The storage tank 1 stores the emulsion raw material, the emulsion tank 2 receives the emulsion delivered by the storage tank 1, the coating device 3 applies the emulsion to the surface of the base paper, and the vibrating screen 4 filters and recovers paper scraps from the emulsion. The storage tank 1 is connected to the emulsion tank 2 via a first infusion pipe, the emulsion tank 2 is connected to the coating device 3 via a second infusion pipe, the coating device 3 is connected to the vibrating screen 4 via a third infusion pipe, and the discharge port of the vibrating screen 4 is connected to the emulsion tank 2 via a fourth infusion pipe, forming a circulating loop of emulsion liquid supplemented by the storage tank 1. The storage tank 1 replenishes the emulsion liquid into the emulsion tank 2 to maintain it within a certain range, the emulsion tank 2 supplies the emulsion liquid to the coating device 3, and the coating device 3 applies the emulsion to the base paper. Excess emulsion liquid flows back to the vibrating screen 4 for filtration and is then recycled back to the emulsion tank 2 for reuse. Among them, cream viscosity control devices 6 are installed on the first liquid delivery pipeline between the storage tank 1 and the emulsion tank 2, the second liquid delivery pipeline between the emulsion tank 2 and the coating equipment 3, and the third liquid delivery pipeline between the coating equipment 3 and the vibrating screen 4.

[0021] The cream viscosity control device 6 includes a heat-insulating shell 6-1. A heating pipe 6-2 is installed inside the shell 6-1. The heating pipe 6-2 includes a metal tube 6-2-1 and a heating wire 6-2-2 wound around the metal tube 6-2-1. The metal tube 6-2-1 is preferably made of copper. Both the inlet and outlet ends of the metal tube extend through the heat-insulating shell 6-1 and connect to the delivery pipe 5 outside the shell 6-1. A temperature sensor 6-3 and a viscosity sensor 6-4 are installed at both the inlet and outlet ends of the heating pipe 6-1. Both the temperature sensor 6-3 and the viscosity sensor 6-4 are located outside the shell 6-1. The head extends into the metal tube 6-2-1 and is sealed to both the metal tube 6-2-1 and the housing 6-1. It monitors the temperature and viscosity of the cream at the inlet and outlet of the control device 6 in real time. In this embodiment, the heating pipe 6-2 adopts an S-shaped layout structure, which effectively increases the length of the pipe inside the control device and extends the heating time. A controller 6-5 is provided outside the heat-insulating housing 6-1 and is electrically connected to the heating wire, temperature sensor and viscosity sensor. The controller 6-5 adjusts the heating power of the electric heating wire 6-2-2 according to the monitoring signals fed back by the temperature sensor 6-3 and the viscosity sensor 6-4, so that the cream maintains a stable viscosity and avoids the heating temperature being too high or too low.

[0022] More preferably, the thermal insulation shell 6-1 includes an outer shell and an inner shell, with thermal insulation cotton sandwiched between the inner and outer shells. The thermal insulation shell 6-1 is filled with thermal insulation filler 6-6, such as perlite or mineral wool, to further improve heating efficiency.

[0023] In the control system, during the feeding process of coating equipment 3, the cream can be heated in two stages through the cooperation of two control devices on the first conveying pipe and the second boundary pipe. This improves the viscosity stability and accuracy of the cream during coating, resulting in a more uniform coating amount and more stable product quality. The temperature and viscosity are further adjusted by a control device on the third conveying pipe to compensate for heat loss during coating, improve the recovery rate of the cream liquid on the vibrating screen 4, and reduce waste.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
