Problems solved by technology

[0003] As disclosed in Chinese patent CN201710977622, ​​there is a screening system for finished toilet paper rolls. This structural system is aimed at the weight detection of a single toilet paper belt scale. The belt scale uses a dynamic sensor and the stability of the belt. During transportation For weight detection, due to the limitations of the structure of the belt scale, the entire paper roll cannot be detected

Embodiment 1

[0031] Such as figure 2 , image 3 , Figure 4 It is the front view, top view and axial side view of the weighing equipment, which includes guide unit, lifting unit, weighing unit, blocking unit and feed plate 5, body plate 2 and foot plate 1, due to the accuracy required for weighing data It must be within 5%, so the anchor plate 1 and the fuselage plate 2 should be fixed with anchor bolts to prevent vibration.

[0032] The most important thing in the whole equipment is the weighing unit. Since the error of the whole system is inversely proportional to the number of load cells, one load cell cannot support the entire weighing platform 3. The load cell uses two beam sensors, In order to make the load cell 9 be subjected to a single force and a small part of the bending moment, a V-shaped block 4 is installed on the weighing platform 3. The function of the V-shaped block 4 is to make the toilet paper 10 on the weighing platform 3 centered. At the same time, the distributio...

Embodiment 2

[0041] On the basis of Embodiment 1, the cylinder 15 of the lifting unit will have an air circuit buffer design, in order to realize that the cylinder has two speeds, high and low, so that the toilet paper can fall steadily on the weighing platform without vibration, allowing the The paper finally falls slowly on the weighing platform 3, which reduces the detection time and improves the detection accuracy.

Embodiment 3

[0043] On the basis of Embodiment 1, the weighing unit cylinder 15 will have three sensors, the lowest position and the highest position respectively have a magnetic switch, and there is a magnetic switch at the position where the cylinder falls to the position where the toilet paper touches the weighing platform 3, The function of this magnetic switch is to switch the air path and change the movement speed of the cylinder. The movement of the weighing unit cylinder is divided into two parts. From the maximum stroke of the cylinder to the toilet paper just touching the weighing platform, the distance from the cylinder is high speed, and it is low speed after entering the weighing platform.

Abstract

The invention provides a weighing machine and a weighing method for toilet paper. The weighing machine is characterized by comprising a weighing unit, which is arranged on a machine body plate, and isformed by a feeding plate, a weighing platform and V-shaped blocks, weighing sensors, and a PLC controller. The weighing platform is designed in an axial manner, and two ends of the weighing platformare set up and fixed by the machine body plates and are connected with an outlet of the feeding plate. The weighing platform is provided with a plurality of V-shaped blocks at equal intervals along the axial direction. Toilet paper is arranged on the weighing platform by using the plurality of V-shaped blocks. The weighing platform is rigidly connected with two groups of weighing sensors and display instruments to fix thereof along the axial direction. The weighing sensor and a PLC controller are connected in a wired manner through a signal line. The weighing machine and the weighing method detect in a static manner, and a single point beam sensor is selected to put the toilet paper on the weighing platform through a specific mechanism for weight detection, and the toilet paper is removedfrom the platform after being weighed. A whole weighing process does not affect subsequent production, and continuity of production is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of toilet paper weight detection, in particular to a toilet paper weighing machine and a weighing method, which can realize hygienic weight detection and adjust the weight of toilet paper in production in real time. Background technique [0002] In recent years, toilet paper production equipment at home and abroad is in a stage of rapid development. The weight error of toilet paper in the market should be within 5% of the marked quality. In order to sell qualified products in toilet paper manufacturing, product quality must be strictly controlled. This requires testing the weight of toilet paper. Due to the blankness of automatic weight detection, toilet paper manufacturers mainly conduct weight detection through manual random sampling. Because the quality of toilet paper web production is not uniform, and the weight also has a certain randomness, there will be toilet paper with unqualified weight during pr...
