Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulp molding production technology, and in particular to a single-cycle pulping system for pulp molding based on automatic control. Background Technology
[0002] In the field of pulp molding product manufacturing, product quality is directly related to a company's market competitiveness and economic benefits. Among these issues, the dark color of the product has become a key factor restricting the improvement of production yield, seriously affecting the product's appearance quality and application range.
[0003] Currently, most pulping systems adopt a cyclical operation mode of "pulp feeding tank - pulp pump - pressure screen - molding machine - return pulp tank - return pulp pump - pulp feeding tank". While this method of recycling pulp achieves resource conservation to some extent, it has significant drawbacks. During mold repair and other maintenance operations on the molding machine, pulp contamination is easily triggered, resulting in numerous dark spots on the product surface and a significant reduction in product qualification rate. Even more problematic is that if a molding machine malfunctions and requires repair, the impurities it generates will rapidly spread with the circulating pulp, contaminating the entire pulping system. This not only causes production to halt on the faulty molding machine but also affects other normally operating molding machines, leading to a decline in product quality and ultimately resulting in a decrease in overall capacity and production efficiency, causing serious economic losses to the enterprise.
[0004] It is evident that the existing pulping system circulation mode can no longer meet the demands of high-quality and high-efficiency production. There is an urgent need to develop a new technical solution that can effectively avoid pulp contamination during molding machine maintenance, reduce the impact of product dark coloring, and improve overall production stability and efficiency. Utility Model Content
[0005] To overcome the technical defects of the existing technology, this utility model provides a single-cycle pulping system for pulp molding based on automatic control. This solves the problem that the pulp used in the above-mentioned molding machine is recycled, but when the molding machine is repaired, it is easy to cause an increase in dark spots on the product. More seriously, when a molding machine malfunctions and needs repair, the impurities generated will contaminate the entire pulping system.
[0006] The technical solution adopted by this utility model is: a single-cycle pulping system for pulp molding based on automatic control, including a machine mechanism with a unidirectional opening at the top, a U-shaped mounting mechanism is attached to the top of the machine mechanism, and a screw hole is opened inside the longitudinal component located on the rear side of the mounting mechanism.
[0007] The mounting mechanism has a screw hole with a fixing bolt screwed inside. The mounting mechanism is limited above the machine platform mechanism by the fixing bolt. The front end of the mounting mechanism is fixedly connected to a longitudinally arranged guide frame assembly. The guide frame assembly has a longitudinal groove inside. A longitudinally arranged servo push rod is fixedly connected inside the longitudinal groove. The bottom end of the servo push rod is fixedly connected to a liquid level module. The top end of the liquid level module is fixedly connected to a ribbon cable for connecting to external control equipment.
[0008] Preferably, a slider assembly is fixedly connected to the outside of the liquid level module. The slider assembly has a structure that protrudes from the liquid level module, and there are two slider assemblies.
[0009] Preferably, the two slider assemblies are fixedly connected to the left and right sides of the liquid level module in opposite directions, and a pad assembly is fixedly connected to the bottom surface of the machine mechanism. The pad assembly is made of rubber.
[0010] Preferably, the pad assembly has four locations, and the four pad assemblies are fixedly connected to the four corners of the bottom surface of the machine mechanism. The pad assembly and the machine mechanism together form a support structure, and an L-shaped slurry supply pipe is fixedly connected to the left end of the machine mechanism.
[0011] Preferably, a supply flange is fixedly connected to the side of the slurry supply pipe away from the machine mechanism, and a control valve A is also installed on the outside of the slurry supply pipe, while an air supply pipe is fixedly connected to the inside of the machine mechanism.
[0012] Preferably, an air supply flange is fixedly connected to the front end of the air supply pipe, and a control valve B is also fixedly connected to the outside of the air supply pipe.
[0013] Preferably, a transversely arranged diversion pipe is fixedly connected to the rear side of the air supply pipe, the diversion pipe is connected to the air supply pipe, and an aeration pipe is fixedly connected to the outer side of the diversion pipe.
[0014] Preferably, there are two aeration pipes, which are fixedly connected to the left and right sides of the diversion pipe in opposite directions, and the top of the outer peripheral surface of the two aeration pipes are provided with aeration holes in a straight array.
[0015] The beneficial effects of this utility model are:
[0016] 1. In this utility model, the pulping system adopts a single-circulation mode. The liquid level module monitors the liquid level in the machine mechanism in real time and transmits the data to the external control equipment for regulation. This can accurately control the amount of pulp and avoid impurities from mixing into the pulp due to abnormal liquid level, thereby reducing the generation of dark spots in the product. At the same time, in the single-circulation mode, each machine mechanism operates independently. Impurities generated during the maintenance of one machine will not spread to the pulp of other machines, effectively preventing contamination of the entire pulping system and ensuring the quality of products produced by other molding machines.
[0017] 2. In this utility model, the slider assembly on the outside of the liquid level module ensures the stability of liquid level monitoring, making the liquid level data more accurate and reliable, and providing a guarantee for the precise control of the pulping system. The rubber pad assembly at the bottom of the machine mechanism plays a buffering and shock-absorbing role, reducing the impact of equipment operation vibration on the pulping process, which is conducive to improving the stability of pulp mixing and reaction, thereby improving pulping quality. The reasonable design of the pulp supply pipe and air supply pipe and the setting of related control valves can accurately control the delivery of pulp and gas, further ensuring the stability of the pulping process and the consistency of product quality, effectively solving the problems of poor stability of the pulping system and the impact on product quality in the prior art.

[0025] The present invention will be further described below with reference to the accompanying drawings:
[0026] like Figures 1-6As shown, this embodiment provides a single-cycle pulping system for pulp molding based on automatic control, including a machine mechanism 1 with a one-way opening at the top, a U-shaped mounting mechanism 3 hanging at the top of the machine mechanism 1, and a screw hole opened inside the longitudinal component located on the rear side of the mounting mechanism 3.
[0027] A fixing bolt 301 is screwed into the screw hole in the mounting mechanism 3. The mounting mechanism 3 is limited above the machine base mechanism 1 by the fixing bolt 301. A longitudinally arranged guide frame assembly 3011 is fixedly connected to the front end of the mounting mechanism 3. A longitudinal groove is opened inside the guide frame assembly 3011. A longitudinally arranged servo push rod 3012 is fixedly connected inside the longitudinal groove. A liquid level module 3013 is fixedly connected to the bottom end of the servo push rod 3012. A ribbon cable 3015 for connecting external control equipment is fixedly connected to the top end of the liquid level module 3013.
[0028] The mounting mechanism 3 is limited by the fixing bolt 301, and the front end is connected to the guide frame assembly 3011. The guide frame assembly 3011 is equipped with a servo push rod 3012, which is connected to the liquid level module 3013 and the cable 3015. This structure realizes the automatic monitoring and control of the liquid level in the machine mechanism 1, and facilitates the transmission of liquid level data to external control equipment so as to adjust the pulping system according to the liquid level.
[0029] Among them, a slider assembly 3014 is fixedly connected to the outside of the liquid level module 3013. The slider assembly 3014 is a structure that protrudes from the liquid level module 3013, and there are two slider assemblies 3014. The two slider assemblies 3014 are fixedly connected to the left and right sides of the liquid level module 3013 in opposite directions. A pad assembly 101 is fixedly connected to the bottom surface of the machine mechanism 1. The pad assembly 101 is made of rubber.
[0030] Two opposing slider assemblies 3014 are connected to the outside of the liquid level module 3013, and a rubber pad assembly 101 is connected to the bottom of the machine mechanism 1. The slider assembly 3014 ensures that the liquid level module 3013 slides smoothly within the guide frame assembly 3011, improving the stability of liquid level monitoring; the rubber pad assembly 101 not only supports the machine mechanism 1, but also buffers and reduces vibration, minimizing the impact of vibration during equipment operation on the pulping process.
[0031] The pad assembly 101 has four parts, which are fixedly connected to the four corners of the bottom surface of the machine mechanism 1. The pad assembly 101 and the machine mechanism 1 together form a support structure. The left end of the machine mechanism 1 is fixedly connected to an L-shaped slurry supply pipe 1011. The side of the slurry supply pipe 1011 away from the machine mechanism 1 is fixedly connected to a supply flange 1012. A control valve A1013 is also installed on the outside of the slurry supply pipe 1011. An air supply pipe 2 is fixedly connected to the inside of the machine mechanism 1.
[0032] There are four pad block assemblies 101, distributed at the four corners of the bottom end face of the machine mechanism 1. The left end of the machine mechanism 1 is connected to the L-shaped slurry supply pipe 1011. The four pad block assemblies 101 make the support more stable. The slurry supply pipe 1011 is used to deliver slurry to the machine mechanism 1. Its L-shaped design makes it easy to connect to external slurry supply equipment and ensure a stable supply of slurry.
[0033] Among them, the front end of the air supply pipe 2 is fixedly connected to the air supply flange 201, and the outer side of the air supply pipe 2 is also fixedly connected to the control valve B2011. The rear side of the air supply pipe 2 is fixedly connected to the transversely arranged diversion pipe 2012, which is connected to the air supply pipe 2. The outer side of the diversion pipe 2012 is fixedly connected to the aeration pipe 2013. There are two aeration pipes 2013. The two aeration pipes 2013 are fixedly connected to the left and right sides of the diversion pipe 2012 in opposite directions. The top of the outer peripheral surface of the two aeration pipes 2013 are provided with aeration holes 2014 in a straight array.
[0034] The end of the slurry supply pipe 1011 away from the machine mechanism 1 is connected to the supply flange 1012, and a control valve A1013 is installed on its outer side. The air supply pipe 2 is connected to the inner side of the machine mechanism 1. The supply flange 1012 facilitates the connection of the slurry supply pipe 1011 to other equipment, and the control valve A1013 can control the flow rate and on / off of the slurry. The air supply pipe 2 provides an air source for subsequent operations such as aeration of the slurry.
[0035] In this automatic control-based single-cycle pulp molding system, the machine mechanism 1 is the fundamental load-bearing component of the entire system. Its top has a one-way opening to accommodate pulp. The mounting mechanism 3 has a U-shaped structure and is screwed into the screw holes inside the longitudinal component on the rear side of the mounting mechanism 3 by fixing bolts 301, thus limiting its position above the machine mechanism 1 and achieving stable installation of the mounting mechanism 3. The front end of the mounting mechanism 3 is fixedly connected to a longitudinally arranged guide frame assembly 3011. A servo push rod 3012 is fixed in the longitudinal groove inside the guide frame assembly 3011, and the bottom end of the servo push rod 3012 is connected to the liquid level module 3. 013, The top of the liquid level module 3013 is connected to the ribbon cable 3015 for connecting to the external control device. When the system is running, the servo push rod 3012 is activated, pushing the liquid level module 3013 to move up and down along the longitudinal groove of the guide frame assembly 3011. The liquid level module 3013 monitors the liquid level height in the machine mechanism 1 in real time and transmits the data to the external control device through the ribbon cable 3015. The external control device controls the extension and retraction of the servo push rod 3012 according to the received liquid level data, thereby adjusting the position of the liquid level module 3013, so as to realize the precise automatic monitoring and control of the liquid level in the machine mechanism 1.
[0036] Two slider assemblies 3014 are fixedly connected to the outside of the liquid level module 3013 and are arranged oppositely on the left and right sides. During the up and down movement of the liquid level module 3013 with the servo push rod 3012, the slider assembly 3014 contacts the inner wall of the longitudinal groove of the guide frame assembly 3011, which plays a guiding and stabilizing role, ensuring that the liquid level module 3013 will not shake or deviate during the movement, and ensuring the accuracy and stability of the liquid level monitoring data.
[0037] Four rubber pad assemblies 101 are fixedly connected to the bottom surface of the machine mechanism 1. They are located at the four corners of the bottom surface of the machine mechanism 1. The pad assemblies 101 provide stable support for the machine mechanism 1, so that the entire pulping system can be placed stably. On the other hand, the rubber material has good buffering and shock absorption performance, which can effectively reduce the impact of the vibration generated by the equipment on the pulping process during the operation of the equipment, and avoid pulp fluctuation caused by vibration, which would affect the pulping quality.
[0038] An L-shaped slurry supply pipe 1011 is fixedly connected to the left end of the machine mechanism 1. A supply flange 1012 is fixedly connected to the side of the slurry supply pipe 1011 away from the machine mechanism 1, which facilitates connection with external slurry supply equipment. A control valve A1013 is installed on the outside of the slurry supply pipe 1011. During the slurry preparation process, when it is necessary to supply slurry to the machine mechanism 1, the control valve A1013 is opened. The slurry in the external slurry supply equipment enters the slurry supply pipe 1011 through the supply flange 1012, and is then transported to the machine mechanism 1 by the slurry supply pipe 1011. The L-shaped design allows the slurry supply pipe 1011 to be connected to external equipment more flexibly, ensuring a stable supply of slurry.
[0039] An air supply pipe 2 is fixedly connected to the inner side of the machine mechanism 1. An air supply flange 201 is fixedly connected to the front end of the air supply pipe 2 for easy connection to external air supply equipment. A control valve B2011 is fixedly connected to the outer side of the air supply pipe 2 to control the gas flow and on / off. A transversely arranged diversion pipe 2012 is fixedly connected to the rear side of the air supply pipe 2. The diversion pipe 2012 is connected to the air supply pipe 2. An aeration pipe 2013 is fixedly connected to each of the left and right sides of the diversion pipe 2012. The outer periphery of the aeration pipe 2013 is provided with aeration holes 2014 arranged in a straight array at the top. When it is necessary to aerate the slurry in the machine mechanism 1, the control valve B2011 is opened. External gas enters the air supply pipe 2 through the air supply flange 201, and then is diverted to the two aeration pipes 2013 through the diversion pipe 2012. Finally, the gas is evenly released into the slurry from the aeration holes 2014 on the aeration pipe 2013, thereby realizing the aeration treatment of the slurry and promoting the uniform mixing and reaction of the slurry.
