Description

Technical Field

[0001] This utility model relates to the field of pulp molding technology, specifically to a pulp molding suction mold that ensures uniform pulp suction. Background Technology

[0002] Pulp molding is a three-dimensional papermaking technology that uses waste paper as raw material and molds it into paper products of a certain shape using special molds on a molding machine. This technology does not require any adhesives and can produce paper products with complex shapes and high dimensional accuracy requirements, making it a technology for obtaining ideal packaging materials.

[0003] Existing patent document CN222275098U discloses a pulp molding suction mold for uniform pulp absorption. This device, through its pressing function, repeatedly squeezes the pulp with pressure plates, thereby fully discharging the liquid inside the pulp. This facilitates the suction equipment to absorb the discharged liquid. Therefore, the device in this application improves the pulp absorption effect. This invention, through its reverse pressing function, can completely press the entire pulp. While this device has many advantages, it still has the following problems: during pulp pressing, solid lumps in the pulp are easily adhered to the outer wall of the support mesh under pressure, making it inconvenient to unload the pressed material and to feed the pulp between the pressure plates and the base. Therefore, we propose a pulp molding suction mold for uniform pulp absorption. Utility Model Content

[0004] The purpose of this invention is to provide a pulp molding die that can uniformly absorb pulp, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pulp molding suction mold for uniform pulp suction, comprising a tank, wherein multiple support columns are provided on the side wall of the tank, multiple support legs are fixedly connected to the bottom of the tank, a top plate is provided on the top of the support columns, a telescopic liquid cylinder assembly is provided on the top of the top plate, and a chassis assembly that is easy to quickly disassemble is provided inside the tank.

[0006] Preferably, the chassis assembly includes a tray disposed inside the tank body, a perforated plate fitted to the bottom of the tray, a mesh plate disposed at the bottom of the tray, a support frame integrally formed on the inner wall of the tank body, and a plurality of vertical columns fixed to the inside of the tank body.

[0007] Preferably, the side wall of the tank is provided with a side opening, and the bottom of the tank is provided with multiple drainage holes.

[0008] Preferably, the hydraulic cylinder assembly includes multiple hydraulic cylinders fixed to the top of the top plate, a small pump station disposed on the side wall of the hydraulic cylinder, a reinforcing frame fixed to the power output end of the hydraulic cylinder, and a pressure plate fixed to the bottom of the reinforcing frame.

[0009] Preferably, the tray has a handle on its side wall and a perforated plate inside.

[0010] Preferably, the outer wall of the tank is provided with a plurality of fixing blocks, which are fixed to the bottom of the support column.

[0011] Preferably, the pressure plate is fitted to the top of the tank, and the mesh plate is disposed inside the tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model has a removable tray inside the tank. When the pulp is placed on the tray and pressed repeatedly with the pressure plate of the liquid cylinder assembly to achieve a uniform pulp absorption effect, the tray can be removed for pulp loading and unloading operations. This solves the problems of material debris adhering to the tray during repeated pressing, which makes unloading inconvenient, and the problem of the tray being located inside the operation and being obstructed by the structure, which makes loading inconvenient. This is conducive to pressing the pulp and achieving uniform pulp absorption for subsequent pulp molding.

[0014] 2. After the pulp is pressed, the tray can be removed from the inside of the tank, and then the wire mesh can be removed from the inside of the tank through the side opening. This allows the internal structure of the tank to be easily removed, making it easier to clean the liquid adhering to the inner wall, thus facilitating the reuse of the device.

Detailed Implementation

[0021] 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.

[0022] Example

[0023] Please see Figures 1-5 The figure shows a pulp molding die for uniform pulp suction, including a tank 100. Multiple support columns 110 are bolted to the side wall of the tank 100. Multiple support legs 101 are bolted to the bottom of the tank 100. A top plate 111 is bolted to the top of the support columns 110. A telescopic hydraulic cylinder assembly is bolted to the top of the top plate 111. A chassis assembly that can be quickly disassembled is provided inside the tank 100.

[0024] Specifically, the chassis assembly includes a tray 130 disposed inside the tank 100, a perforated plate 132 fitted to the bottom of the tray 130, a mesh plate 140 disposed at the bottom of the tray 130, a support frame 150 integrally formed on the inner wall of the tank 100, and a plurality of vertical columns 151 fixed to the inside of the tank 100 by bolts.

[0025] Furthermore, the tank body 100 has a side opening 141 on its side wall and multiple drainage holes 152 are machined at the bottom of the tank body 100. After connecting the pipes at the bottom of the drainage holes 152, it is convenient to collect the slurry and facilitate subsequent slurry suction treatment.

[0026] Furthermore, the hydraulic cylinder assembly includes multiple hydraulic cylinders 112 bolted to the top of the top plate 111, a small pump station 113 disposed on the side wall of the hydraulic cylinder 112, a reinforcing frame 121 fixed to the power output end of the hydraulic cylinder 112, and a pressure plate 120 fixed to the bottom of the reinforcing frame 121. The hydraulic cylinder 112 uses a common model on the market. The hydraulic cylinder is composed of a cylinder body, piston, piston rod, sealing device, end cover and oil port, etc. It is connected to a common external small pump station 113. The small pump station 113 is composed of a hydraulic pump, oil tank, pressure regulating valve, etc. It mainly converts mechanical energy into high-pressure liquid energy through the hydraulic pump, and then delivers it to the hydraulic cylinder or other actuators through pipelines to realize force transmission and motion control. In simple terms, the working principle of a hydraulic pump station is to use a pump to generate high-pressure oil, and control valves to regulate the direction and pressure of the oil flow, thereby driving the hydraulic cylinder to complete various mechanical actions. The small pump station 113 is equipped with a control panel with common electrical connections. The control panel is powered by an external power source connected by a power cord. The extension and retraction of the hydraulic cylinder 112 causes the piston rod to pass through the top plate 111, causing the pressure plate 120 to move downward to press the pulp on the tray 130.

[0027] Furthermore, the side wall of the tray 130 is fixed with a handle 131 by bolts, and the inside of the tray 130 is provided with a perforated plate 132.

[0028] It is worth noting that the outer wall of the tank 100 has multiple fixing blocks connected by bolts, and the fixing blocks are fixed to the bottom of the support column 110 by bolts.

[0029] It is worth noting that the pressure plate 120 is fitted to the top of the tank 100, and the mesh plate 140 is disposed inside the tank 100.

[0030] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0031] Working principle: By providing an outwardly removable tray 130 inside the tank 100, the pulp can be repeatedly pressed on the tray 130 in conjunction with the pressure plate 120 of the liquid cylinder assembly to achieve uniform pulp absorption. During processing, the tray 130 can be removed for pulp loading and unloading operations. This solves the problems of material debris adhering to the tray 130 during repeated pressing, which makes unloading inconvenient, and the problem of the tray 130 being obstructed by the structure inside the operation, which makes loading inconvenient. This facilitates the pressing of the pulp and enables uniform pulp absorption for subsequent pulp molding. After the pulp pressing, the tray 130 can be removed from inside the tank 100, and then the wire mesh 140 can be removed from inside the tank 100 through the side opening 141. This allows for convenient removal of the internal structure of the tank 100, facilitating the cleaning of liquid adhering to the inner wall, and thus promoting the reuse of the device.
