A high-strength, high-capacity dewatering roller

Abstract

This utility model discloses a high-strength, high-capacity dewatering roller, comprising a roller body, a locking device, and a stainless steel sheet. The roller body has external threads at both ends. The locking device includes two rings with internal threads inside, which engage with the external threads. The two rings are tightened and fixed to both ends of the roller body. The stainless steel sheet wraps around the outside of the roller body, and its outer edge is cylindrical. The stainless steel sheet is pressed and fixed to the outside of the roller body by the rings. The width of the stainless steel sheet's cross-section near the roller body is greater than the width away from the roller body. Several grooves for drainage are formed on the outer edge of the stainless steel sheet. Compared to traditional dewatering rollers with rubber and polyurethane coatings on metal rollers, the stainless steel sheet forms more water-holding grooves, improving its dewatering capacity and effectively enhancing its wear resistance and service life. Furthermore, the roller body itself has no openings or grooves, ensuring rigidity and preventing deformation even when the roller length is increased.

Description

Technical Field

[0001] This utility model relates to the field of paper dewatering roller technology, specifically a high-strength, high-water-capacity dewatering roller. Background Technology

[0002] In the production of blankets, fibers, and paper products, washing or dissolving with water is often necessary to achieve certain technical specifications. However, the final product cannot contain excessive water. Therefore, it is crucial to remove moisture from the product, and the key equipment for this is the roller, which removes excess water through compression. In recent years, with the expansion of production scale, increased width, and faster speeds, higher demands have been placed on the performance of compression rollers.

[0003] Traditional extrusion rollers are typically made by coating the surface of a steel roller with rubber, polyurethane, or composite materials. However, this approach has the following problems: the surface coating with rubber, polyurethane, or composite materials has poor wear resistance and the surface is easily damaged by other products it comes into contact with; at the same time, it is necessary to groove or drill holes on the material surface, but the rigidity of the coating material itself is limited, so the number of holes cannot be increased, which leads to insufficient water-holding space; and the maintenance cost of this type of coating material is high, and the maintenance interval is short.

[0004] (I) Technical Solution

[0005] To solve the above-mentioned technical problems, this utility model provides a high-strength, high-capacity dewatering roller.

[0006] The specific technical solution is as follows: a high-strength, high-capacity dewatering roller, comprising a roller body, a locking device, and a stainless steel sheet. The roller body has external threads at both ends. The locking device includes two rings with internal threads inside. The internal threads cooperate with the external threads. The two rings are tightened and fixed at both ends of the roller body. The stainless steel sheet is wrapped around the outside of the roller body, and the outer edge of the stainless steel sheet is cylindrical. The stainless steel sheet is pressed and fixed to the outside of the roller body by the rings. The width of the cross-section of the stainless steel sheet on the side closer to the roller body is greater than the width on the side farther from the roller body. The outer edge of the stainless steel sheet forms several grooves for drainage.

[0007] Furthermore, the stainless steel sheet is an integral structure with an overall spiral shape. The cross-section of the stainless steel sheet is irregular, consisting of upper and lower parts, with the upper part being rectangular or trapezoidal and the lower part being rectangular. In the axial section of the stainless steel sheet along the roller body, a groove for drainage is formed between the cross-sections of two adjacent stainless steel sheets.

[0008] Furthermore, the stainless steel sheet is an integral structure with an overall spiral shape and a trapezoidal cross-section. In the axial section of the stainless steel sheet along the roller body, a groove for drainage is formed between two adjacent stainless steel sheet sections.

[0009] Furthermore, the stainless steel sheet has a split structure, including multiple annular units fitted on the roller body. The inner diameter of each annular unit is the same as the outer diameter of the roller body. The cross-section of the annular unit is irregular, consisting of upper and lower parts, with the upper part being rectangular or trapezoidal and the lower part being rectangular. A groove for drainage is formed between two adjacent annular units.

[0010] Furthermore, the groove formed by the stainless steel sheet is provided with protrusions, the width of which is the same as the width of the groove.

[0011] Furthermore, the stainless steel sheet is a one-piece structure, with an overall spiral shape. The cross-section of the stainless steel sheet is irregular, consisting of upper and lower parts, both of which are rectangular. The lower part has a thickness of 2-3mm and a height of 5-10mm, while the upper part has a thickness of 1-1.5mm and a height of 3-10mm. The groove is 0.5-15mm wide and 3-10mm deep. Adjacent cross-sections form a drainage channel.

[0012] (ii) Beneficial effects

[0013] Compared with the prior art, the technical solution proposed in this utility model wraps a layer of stainless steel sheet around the outside of the roller. The stainless steel sheet has an irregular shape with a smaller top and a larger bottom. This allows two adjacent stainless steel sheets to form water-retaining grooves. Compared with the traditional dewatering roller structure of rubber and polyurethane wrapped around a metal roller, the stainless steel sheet forms more water-retaining grooves, which improves its dewatering capacity, effectively improves wear resistance, and extends service life. At the same time, the roller body itself has no holes or grooves, ensuring rigidity, and there will be no deformation even if the length of the roller is increased. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0023] To address the problems existing in the relevant prior art, this utility model proposes a high-strength, high-capacity dewatering roller. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] Example 1:

[0025] Please see Figure 1 A high-strength, high-capacity dewatering roller includes a roller body 1, a locking device, and a stainless steel sheet 2. The roller body 1 has external threads at both ends. The locking device includes two rings 3 with internal threads inside. The internal threads cooperate with the external threads. The two rings 3 are tightened and fixed at both ends of the roller body 1. The stainless steel sheet 2 is wrapped around the outside of the roller body 1, and the outer edge of the stainless steel sheet 2 is cylindrical. The stainless steel sheet 2 is pressed and fixed to the outside of the roller body 1 by the rings 3. The width of the cross section of the stainless steel sheet 2 on the side closer to the roller body 1 is greater than the width on the side farther away from the roller body 1, so that the outer edge of the stainless steel sheet 2 forms several grooves 4 for drainage.

[0026] In practical use, this dewatering roller works in conjunction with another roller. Products that need to be dewatered, such as paper or blankets, pass between the two rollers. The two rollers squeeze each other to remove the moisture from the raw materials. Compared with traditional rubber materials, stainless steel sheets effectively improve wear resistance, and the irregular structure forms water-retaining grooves on the outer edge. Compared with the traditional method of opening holes on the roller surface for drainage, it also ensures the overall rigidity of the roller, so that even if the length of the roller is increased, there will be no deformation.

[0027] For details, please refer to Figures 2 to 6The stainless steel sheet 2 is an integral structure with an overall spiral shape. It can be integrally formed by the stainless steel sheet through a vertical winding process. This forming process is only for illustrative purposes and is not intended as a specific technical limitation. The cross-section of the stainless steel sheet 2 is irregular, consisting of two parts, an upper part that is rectangular or trapezoidal and a lower part that is rectangular. Here, the upper part refers to the side away from the roller body 1 when in use, and the lower part refers to the side close to the roller body 1. In the cross-section of the stainless steel sheet 2 along the axial direction of the roller body, a groove 4 for drainage is formed between the cross-sections of two adjacent stainless steel sheets.

[0028] Meanwhile, the cross-section of the stainless steel sheet 2 can also be trapezoidal, and the width on the side away from the roller body is smaller than the width on the side close to the roller body 1. In this way, in the axial section of the stainless steel sheet 2 along the roller body 1, a groove 4 for drainage is formed in the middle of the cross-section of two adjacent stainless steel sheets.

[0029] in Figure 2 This indicates that the upper and lower parts of the stainless steel sheet 2 are rectangular, and the groove 4 formed by two adjacent cross-sections is also rectangular. Figure 3 This indicates that the stainless steel sheet has a trapezoidal upper section and a rectangular lower section. In this case, the groove formed by two adjacent sections has a triangular cross section. Figure 6 This indicates that the groove structure is formed when the cross-section of the stainless steel sheet 2 is trapezoidal, and the cross-section of the two adjacent grooves 4 is triangular.

[0030] Furthermore, when the stainless steel sheet 2 is a one-piece structure, the overall shape is spiral, and the distance between two adjacent turns is not specifically limited. Please refer to [link / reference needed]. Figure 3 At this point, the distance between two adjacent rings is 0, and the stainless steel sheet 2 is tightly packed on the surface of the roller body 1. Please refer to [link / reference]. Figure 3 At this point, the distance between two adjacent rings is not 0, and the groove 4 between two adjacent rings of stainless steel sheet 2 is larger, and the water capacity is also larger.

[0031] When the stainless steel sheet 2 is a one-piece structure, the whole is spiral-shaped. The cross-section of the stainless steel sheet 2 is irregular, including upper and lower parts. The upper and lower parts are both rectangular. The thickness of the lower part is 2-3mm and the height of the lower part is 5-10mm. The thickness of the upper part is 1-1.5mm and the height is 3-10mm. The groove size is 0.5-15mm wide and 3-10mm deep. The two adjacent cross-sections form a groove for drainage.

[0032] Example 2:

[0033] The difference from Embodiment 1 is that the stainless steel sheet 2 has a split structure, including multiple annular units 5 sleeved on the roller body 1. The inner diameter of each annular unit 5 is the same as the outer diameter of the roller body 1. The cross-section of the annular unit 5 is irregular, including upper and lower parts, wherein the upper part is rectangular or trapezoidal and the lower part is rectangular. A groove for drainage is formed between two adjacent annular units 5.

[0034] In the above scheme, multiple annular units are fixed to the outside of the roller body 1, and the thickness of each annular unit 5 on the side closer to the roller body is greater than the thickness on the side farther away from the roller body 1. In this way, an annular groove is formed on the outermost side of the roller body 1, which can also effectively discharge the water generated by extrusion.

[0035] Please see Figure 7 A protrusion 6 is provided in the groove 4 formed by the stainless steel sheet 2. The width of the protrusion 6 is the same as the width of the groove 4. The protrusion 6 can play a supporting role, which can effectively prevent the groove 4 from deforming and thus affecting the water removal effect.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
