Problems solved by technology

[0004] In order to solve the above-mentioned problems, the present invention proposes a paper pulp repairing machine and its control method using the bottom water inlet method, which realizes the water supply of the repair tank by using the bottom water inlet method, can effectively utilize the structure and volume of the repair tank, and effectively filter out water flow fluctuations , make the water flow more stable, prevent excessive fluctuations in the water supply flow from causing damage to the paper to be repaired in the repair tank, and the drainage process does not require a water pump, which effectively avoids excessive negative pressure in the repair tank caused by pump suction and avoids waiting for repair The problem of damaged paper effectively guarantees the safety of the paper to be repaired

Embodiment 1

[0034] like figure 1 As shown in the figure, this embodiment provides a pulp repairing machine that adopts the water inlet method, which can be used for repairing damaged and moth-eaten document paper. The pulp repairing machine in this embodiment includes a repairing tank 1, a first pipeline 2, a first A valve 3, a second pipe 4, a water storage tank 5, a water pump 6, a return pipe 7, a third valve 8, a drain pipe 9, a fourth valve 10, a water inlet pipe 11, a second valve 12, a water supply pipe 13, and a water supply device 14 ;

[0035] The repair groove 1 has a water passage 101 at the lower end; it can be understood that the function of the water passage 101 is that the water in the repair groove can be injected through the water passage 101 or discharged through the water passage 101;

[0036] The first pipe 2 communicates with the repair groove 1 through the water passage 101; a deflector 106 is provided at the connection between the water passage 101 and the repair ...

Embodiment 2

[0057] The present embodiment provides a method for controlling a pulp repairing machine using the water inlet method, and adopts the pulp repairing machine adopting the lower water inlet method as described in Embodiment 1, including:

[0058] The repair tank 1 is supplied with water, the first valve 3, the second valve 12 and the third valve 8 are closed, the fourth valve 10 is opened, and the water in the water storage tank 5 passes through the return pipe 7, the fourth valve 10 and the water pump 6 under the action of the water pump 6. The water inlet pipe 11 flows into the first pipe 2, and the water in the first pipe 2 enters the repair tank 1 through the water passage 101 at the lower end of the repair tank 1;

[0059] The repair tank 1 is drained, the first valve 3 is opened, the second valve 12, the third valve 3 and the fourth valve 10 are closed, the water in the repair tank 1 flows into the first pipe 2 under the action of gravity, and the water in the first pipe 2 ...

Abstract

The invention belongs to the technical field of protection of paper literature cultural relics and provides a paper pulp repairing machine adopting a lower water inlet mode and a control method of the paper pulp repairing machine. After a second valve is opened and a first valve is closed, water flow in a water inlet pipe passes through a first pipeline and then enters a repairing groove from a water passing opening in the lower end of the repairing groove; water supply of the repairing groove can be achieved in a lower water inlet mode, water flow is effectively buffered, water flow fluctuation is avoided, and the problem that to-be-repaired paper in the repairing groove is damaged due to the fact that water supply flow fluctuation is too large is solved. Meanwhile, after the second valve is closed and the first valve is opened, water in the repairing groove can flow to the first pipeline, the valve and the second pipeline at the water passing opening under the action of gravity and is finally discharged into the water storage tank, and a water pump is not needed in the water discharging process; the problem that the negative pressure of the repairing groove is too large due to suction of the water pump, and the to-be-repaired paper is damaged is effectively solved, and the safety of the to-be-repaired paper is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of the protection of paper documents and cultural relics, and in particular relates to a pulp repairing machine and a control method thereof adopting a water inlet method. Background technique [0002] The pulp repairing machine is a special equipment for repairing damaged paper documents. Fill the damaged area to achieve the purpose of repairing damaged paper. [0003] The inventor found that the existing pulp repairing machine adopts the top water inlet or side water inlet method, that is, the inlet of the water inlet pipe is arranged above or on the side wall of the repair tank / repair tank, and the water flow is large and the water flow fluctuates when the water enters. The excessive fluctuation of water flow will cause damage to the paper to be repaired in the repair tank to a certain extent; at the same time, in the existing pulp repair machine, the realization of the water outlet method is to set a pu...
