Description

Technical Field

[0001] This utility model relates to the technical field of paper testing equipment, specifically a paper tear test device. Background Technology

[0002] Molded pulp tableware is made from various plant fiber pulps, such as sugarcane bagasse, through processes including structural design, pulping, mixing, molding, pressing, drying, and sterilization. It produces various shapes and sizes of paper tableware, a technology already well-developed abroad and newly emerging in China. These environmentally friendly green fast food utensils are characterized by advanced technology, pollution-free production, low energy consumption, and environmental friendliness. The pulp undergoes changes in fiber morphology, such as expansion, splitting, cutting, fibrillation, and crushing, after passing through beating equipment. This gives the pulp a certain binding force, allowing it to interweave well on the paper wire during papermaking and adapt to the different properties of various papers. The process of mechanically processing fibers to meet process quality requirements is called beating, and the degree of beating is expressed as beating degree. Beating degree refers to the degree of fiber splitting and fibrillation after refining, increasing the specific surface area and giving the fibers better adsorption capacity. In actual production, it is necessary to ensure that the wet pulp has a high degree of beating and that the fiber length is appropriate, so that the pulp can be easily dewatered under specific conditions. Therefore, rapid detection of pulp beating is a prerequisite for guiding actual production. In order to ensure the accuracy of the detection and ensure that the detection data can effectively guide production, there is a need for a detection device that can quickly detect pulp beating. However, existing detection devices for pulp beating mostly rely on centrifuge drying and multiple measurements, which cannot quickly detect pulp beating.

[0004] The purpose of this invention is to provide a paper tear test device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A paper beating test device includes a base, with connecting rods fixed at the four corners of the lower surface of the base, and a knob on the other side of each connecting rod. The connecting rods have threads on the side near the knobs, and a threaded hole matching the threads is formed in the center of the knob. A rubber layer is laid on the lower surface of the knob. A filter bucket is placed above the base, and a separation chamber is formed inside the filter bucket. A filter screen is placed inside the separation chamber, and a side flow pipe is inserted into the bottom of the side wall of the separation chamber. A bottom hole is formed at the bottom of the separation chamber. A mounting platform is fixed to the side wall of the filter bucket, and a support column is fixed between the bottom of the mounting platform and the upper surface of the base. A support rod is fixed to the upper surface of the mounting platform, and a rope wheel is rotatably connected to the top of the support rod. A handle is fixed to the side wall of the rope wheel, and a connecting rope is wound around the rope wheel. A counterweight is fixed to the other end of the connecting rope. A rack is meshed with one side of the rope wheel, and a sealing cone is fixedly installed at the bottom end of the rack.

[0007] As a further embodiment of this utility model, the inner cavity of the separation chamber is composed of two parts: the upper part is a straight cylindrical part with an inner diameter of 112.9 mm and a height of 35 mm, and the lower part of the separation chamber is a conical part with a cone angle of 40°.

[0008] As a further embodiment of this utility model, the upper inner diameter of the filter bucket is 137mm, the lower inner diameter is 112.9±0.1mm, and the angle of the transition part connecting the upper and lower parts of the sealing cone is 45°.

[0009] As a further embodiment of this invention, the filter screen is installed between the straight cylinder and the conical section of the separation chamber. The filter screen material is phosphor bronze wire, and the working area of ​​the filter screen is 100 cm². 2 The filter screen is 0.4mm thick, with 24 weft threads and 32 warp threads per 10mm, where the diameter of the weft threads is 0.17mm and the diameter of the warp threads is 0.16mm.

[0010] As a further embodiment of this utility model, the insertion angle between the side flow tube and the lower conical part of the separation chamber is 49°, the outer diameter of the side flow tube is 19±0.1mm, the inner diameter is 16±0.1mm, and a bevel is cut at the upper end of the side flow tube, with the bevel forming an angle of 12° with the center line of the cone.

Two axially mounted blades are located on the symmetrical part of the outer circle at the bottom of the copper tube to prevent the pulp suspension from generating vortices. A rubber sealing ring is embedded on the reverse conical surface at the bottom of the sealing cone. The hardness of the rubber sealing ring is 30° Shore.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention utilizes a separation chamber. By gripping the handle and rotating the rope wheel, a rack engaged with one side of the rope wheel descends, causing the sealing cone at the bottom of the rack to be placed into the separation chamber within the filter bucket. The suspension sample is then poured into the filter bucket. After five seconds, the handle is reversed, causing the weight at the other end of the connecting rope to fall under gravity. At this point, the sealing cone is released, and the suspension sample is discharged through the filter bucket mesh via the bottom hole and the side flow pipe. Once the side flow pipe stops dripping, the reading on the SR measuring cylinder at the bottom of the side flow pipe is taken, which is the measurement result. Compared to the existing technology that involves centrifuging and multiple measurements, this invention allows for a faster and more convenient detection of pulp beating degree.
