Description

Technical Field

[0001] The invention belongs to the technical field of shrinking equipment, and in particular relates to a shrinking roller with random rubbing for a shrinking machine. Background Art

[0002] Utilizing the principle that the fibers in wool fabrics are intertwined and entangled and felted under the influence of moisture, temperature and pressure, the wool textile dyeing and finishing field often requires the use of felting machines to shrink wool fabrics, making the fabric structure thick and tight, forming a certain suede surface and body, thereby improving the appearance and feel of the fabric, and enhancing its elasticity, warmth retention, strength and dimensional stability.

[0003] The shrinking machine is generally composed of shrinking drum, shrinking box, pressure device, shrinking roller, dividing frame, liquid storage box, machine slot and transmission mechanism. When working, the blank enters between the upper and lower shrinking drums, squeezes the blank under pressure and friction, and sends the blank into the shrinking box for further squeezing. Therefore, the shrinking drum is a key component of the shrinking machine.

[0004] For a long time, most shrinking rollers are made of oak or synthetic materials (such as bakelite, rubber), and the surface of the roller is made of only one material. In this way, the friction between the fabric and the roller is relatively smooth, and the friction force lacks random changes. In this way, the folding of the cloth will be prone to shrinkage defects such as "warp stripe creases" due to lack of rubbing and displacement during long-term operation. In addition, shrinking agent must be added to the cloth from the liquid storage tank during shrinkage. If it is not controlled well and too much is added, slipping will occur when the vehicle speed is increased, thereby causing shrinkage defects such as "wear". Summary of the invention

Through different materials, or different sections of the same material, or different material processing, two kinds of shrinking rollers with different friction coefficients with the cloth are produced.

[0013] As a preferred embodiment of the above technical solution, the adjustment portion is in a shape of a circle, an ellipse, a regular polygon, etc.

[0014] As a preferred embodiment of the above technical solution, the adjustment portion is exposed from the circumferential roller surface, or is flush with the circumferential roller surface.

[0015] As a preferred embodiment of the above technical solution, the circumferential drum surface is divided into a left semicircular surface and a right semicircular surface, and the left semicircular surface and the right semicircular surface are respectively composed of a number of small arc surfaces connected in sequence, and the adjustment parts on each small arc surface are divided into a number of rows along the circumferential direction of the outer ring, and each row of adjustment parts is composed of a number of adjustment parts arranged radially along the outer ring.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Example 1

[0027] like Figure 1-2 As shown, a shrinking roller of a shrinking machine with random rubbing includes a shaft 1 and a roller body installed on the shaft 1, and the roller body includes a circumferential roller surface 2 and a plurality of adjustment parts 3 evenly distributed on the circumferential roller surface. The roller body includes an inner ring 4 and an outer ring 5, and the circumferential roller surface 2 is the circumferential surface of the outer ring 5. A plurality of mounting holes 6 are distributed on the circumferential roller surface 2, and plug rods 7 are fixedly installed in the mounting holes 6 respectively. The ends of the plug rods 7 are inserted into the mounting holes, and the head end surfaces of the plug rods 7 constitute the adjustment parts 3. The adjustment parts 3 are flush with the circumferential roller surface 2 and cooperate with the circumferential roller surface 2. Two shrinking rollers are arranged side by side up and down, and the cloth is shrunk between the two shrinking rollers. During the shrinking process, due to the existence of the adjustment parts, the friction force of the upper and lower shrinking rollers on the cloth will be randomly inconsistent, resulting in random rubbing of the cloth when it is rubbed and extruded, such as Figure 4 From the front (as shown Figure 5 ) It can be seen that the friction between the upper circular adjustment part of the tangent line of the two shrinking rollers and the cloth, and the friction between the circumferential roller surface 2 and the cloth will also be randomly inconsistent, resulting in left and right rubbing.

[0028] Furthermore, the ends of the insertion rods 7 are respectively perpendicular to the axis of the drum body.

[0029] Furthermore, the shrinking cylinder further includes an inner sleeve 8, which is located between the inner ring 4 and the shaft 1, the inner ring 4 and the shaft 1 are connected by a key pin 9, the inner sleeve 8 and the inner ring 4 are connected by a key pin 9, and the outer ring 5 and the inner ring 4 are connected by a plurality of screws 10. This can facilitate the assembly of the shrinking cylinder and also facilitate the disassembly and maintenance of the shrinking cylinder.

[0031] Furthermore, in this embodiment, the outer ring 5 and the insertion rod 7 are made of two kinds of wood of the same material but with different grain directions. Furthermore, in this embodiment, the adjustment portion 3 is circular.

[0032] Furthermore, the circumferential roller surface 2 is divided into a left semicircular surface 14 and a right semicircular surface 15, and the left semicircular surface 14 and the right semicircular surface 15 are respectively composed of a plurality of small arc surfaces 16 connected in sequence, and the adjustment parts on each small arc surface 16 are divided into a plurality of rows along the circumferential direction of the outer ring 5, and each row of adjustment parts is composed of a plurality of adjustment parts 3 arranged radially along the outer ring 5. The circumferential roller surface 2 is divided into a left semicircular surface 14 and a right semicircular surface 15, and the adjustment parts 3 on the left semicircular surface 14 and the adjustment parts 3 on the right semicircular surface 15 are independent of each other, so that the rubbing of the cloth on the circumferential roller surface 2 can be promoted.

[0033] Furthermore, the number of adjustment parts 3 in each row of adjustment parts on the small arc surface 16 gradually decreases along the rotation direction of the outer ring 5, the adjustment parts 3 in two adjacent rows of adjustment parts are staggered, and the small arc surface 16 on the left semicircular surface 14 and the small arc surface 16 on the right semicircular surface 15 are staggered. This can further improve the rubbing effect of the cloth on the circumferential drum surface 2.
