Spiral cloth storage tank structure of cloth dyeing machine

Abstract

This invention provides a spiral fabric storage tank structure for a dyeing machine, comprising: a central column, which is an inverted cone; a spiral body disposed on the outer edge of the central column, the spiral body gradually widening from top to bottom, and the spiral pitch gradually narrowing from top to bottom, with the top end being the fabric inlet and the bottom end being the fabric outlet; a plurality of arc-shaped surrounding plates covering and fixed to the outer periphery of the spiral body, thereby forming a cylindrical spiral fabric storage tank; and a nozzle disposed above the spiral fabric storage tank for guiding the passing fabric into the fabric inlet, allowing the fabric to be immersed and dyed along the spiral body in a swirling motion. Because the volume of the flow channel in the spiral fabric storage tank gradually increases from top to bottom, the water flow velocity gradually slows down under the combined effect of the widening and heightening of the flow channel, thereby enabling the fabric to achieve full expansion and thorough dyeing within the flow channel. This invention solves the problem of smooth fabric circulation in the spiral fabric storage tank without the need for a fabric arrangement device, thus also reducing equipment costs and energy consumption.

Description

Technical Field

[0001] This invention relates to a dyeing machine, and more particularly to a spiral storage tank structure for a dyeing machine in which the spiral body of the storage tank gradually expands in width and gradually widens in pitch from top to bottom, so that the fabric can be fully stretched and dyed in response to the water flow speed and centrifugal force, thereby avoiding creases. Background Technology

[0002] like Figure 1 The diagram shows the structure of a spiral dyeing machine 900, which discloses a fabric storage tank 930 disposed within a body 920; a spiral body 940 disposed within the fabric storage tank 930, spiraling downwards, with its bottom end connected to an outlet 933; and a nozzle 950 disposed above the fabric storage tank 930 to guide the passing fabric 960 above the fabric storage tank 930, allowing the fabric 960 to be dyed along the spiral body 940 in a swirling motion. While this spiral dyeing machine offers the benefit of reducing the bath ratio and saving energy, when the fabric is stacked from top to bottom, due to water flow velocity, gravity, and the weight of the fabric, the layers become increasingly compacted towards the bottom, leading to poor fabric flow and resulting in creases.

[0003] like Figures 2A-2C The diagram shows the structure of a dyeing machine 810 equipped with a fabric-swinging device. The dyeing machine 810 includes a fabric storage cylinder 811, a fabric inlet 812, an outer cylinder wall 813, a nozzle 820, a sliding assembly 830, and a swing assembly 840. The swing assembly 840 drives the sliding assembly 830 to slide laterally, supporting the horizontal swing of the fabric-swinging guide tube 823, guiding the fabric C through the fabric inlet 812 into the fabric storage cylinder 811, thereby improving the smoothness of the dyeing machine's operation. However, after the fabric C passes through the nozzle 820 and the fabric-swinging guide tube 823, it enters the fabric storage cylinder 811. Because the width of the flow channel in the fabric storage cylinder 811 suddenly increases relative to the fabric guide tube 823, the fabric C will be driven to move rapidly in a straight line along the outer side of the inner edge of the fabric storage cylinder 811 under the combined action of the impact of the high-speed water flow generated by the nozzle 820 and the centrifugal force generated by the spiral motion of the fabric C in the fabric storage cylinder 811. This phenomenon not only makes the swing of the fabric guide tube 823 ineffective, but also causes the fabric C to be arranged inconsistently, resulting in twisting. In addition, the accumulation of fabric due to gravity makes the cyclic dyeing effect not smooth. Summary of the Invention

[0004] Therefore, the main objective of this invention is to provide a dyeing machine with a spiral fabric storage tank structure, wherein the spiral body has a gradually expanding width and a gradually widening pitch, so as to drive the fabric to fully stretch in response to the water flow speed and centrifugal force, thereby achieving a smooth circulating dyeing effect.

[0005] To achieve the above objectives, the technical means adopted by the present invention include: a central column, which is an inverted cone-shaped structure with a larger upper end and a smaller lower end; a spiral body disposed on the outer periphery of the central column, spiraling downwards, with a progressive structure that is narrow at the front end and wide at the rear end, and its top end being the fabric inlet and its bottom end being the fabric outlet; a plurality of arc-shaped surrounding plates covering and fixing the outer periphery of the spiral body, so that the spiral body forms a flow channel and thereby constitutes a cylindrical spiral fabric storage tank, and the spiral body, in conjunction with the gradually narrowing outer diameter of the inverted cone central column, causes the width of the spiral body to spirally and progressively expand downwards with the height difference, so that the flow channel has a spiral rotation and gradually widening pattern; and a nozzle disposed above the spiral fabric storage tank, used to guide the passing fabric into the fabric inlet, so that the fabric is immersed and dyed along the flow channel.

[0006] In this way, the spiral gradually widens from top to bottom, and the water flow from the nozzle gradually slows down under the effect of the widened flow channel. The water flow will further drive the fabric to fully extend in the flow channel, thereby achieving the effect of smooth circulation and dyeing of the fabric.

[0007] Based on the aforementioned features, the inverted cone of the central column forms an angle of 5 to 30 degrees with its central axis.

[0008] Based on the aforementioned features, the spiral body is composed of more than N plates, where N > 3. Each plate has a circular hole in the middle that matches the central column, and the outer periphery of each plate is a circular edge. The plate is radially cut from the circular hole to the circular edge, forming a first tangent and a corresponding second tangent. The first tangent and the second tangent are staggered vertically along the axial direction of the central column, forming a pitch with a height difference. The pitch of the first to the Nth plates increases sequentially from top to bottom. This connects and fixes the plates to the central column, forming a spiral body that gradually opens from top to bottom.

[0009] Based on the aforementioned features, the width ratio of the second cut edge at the bottom of each plate to the adjacent first cut edge at the top must be greater than 1, and so on, so that the width of the spiral gradually widens from top to bottom; at the same time, the pitch ratio of the lower plate to the adjacent upper plate must also be greater than 1, and so on, so that the pitch gradually increases from top to bottom.

[0010] Based on the aforementioned features, among the N plates of the spiral, one or more plates can be selected as needed to further provide a sandwich structure. The sandwich structure is located at a predetermined position of the plate, and a clamping plate forms a sandwich space with the plate. A plurality of perforations are provided in the sandwich space, and a water inlet is provided on one side of the sandwich space, so that water enters the sandwich space through the water inlet and overflows from the perforation.

[0011] Based on the aforementioned features, it further includes a platform disposed below the spiral fabric storage trough, and the platform surface is provided with a plurality of mesh holes, and the periphery of the platform is provided with two or more guide wheels.

[0012] Based on the aforementioned features, it further includes a receiving groove disposed on the side of the spiral fabric storage trough and positioned relative to the fabric outlet, for receiving the fabric output from the fabric outlet.

[0013] Using the aforementioned features, the "spiral fabric storage tank structure of the dyeing machine" of this invention combines a central column of an inverted cone and a spiral body extending downwards to form a spiral fabric storage tank structure. The width of the spiral body gradually expands from top to bottom, and its pitch gradually widens from top to bottom. As the volume of the flow channel gradually increases, the water flow velocity gradually slows down under the combined effect of the widening and heightening of the flow channel. The fabric is carried by the water flow and rotates along the spiral body, allowing the fabric to fully extend in the flow channel, thereby achieving a full dyeing effect. Since this invention can solve the problem of smooth circulation of fabric in the spiral fabric storage tank without the need for a fabric placement device, this invention also has the benefits of reducing equipment costs and energy consumption.

Detailed Implementation

[0030] The present invention relates to a "spiral fabric storage trough structure for a fabric dyeing machine," wherein the spiral fabric storage trough is disposed within the body of the fabric dyeing machine; the structure of the fabric dyeing machine is as follows: Figures 3A-3CAs shown, it includes: a torso 10, two side covers 11, a fabric inlet 12, a pump 13, an inlet pipe 14, and an outlet pipe 15; a spiral fabric storage trough 20, which is disposed inside the torso 10 corresponding to the fabric inlet 12, and has a fabric lifting wheel 16 and a fabric guide pipe 17 at its front end; the spiral fabric storage trough 20 structure includes: a central column 21, which is a vertical inverted cone with a larger upper end and a smaller lower end, and the angle θ between the inverted cone and its central axis is designed and adjusted to be between 5 and 30 degrees according to the type of fabric and the height of the spiral fabric storage trough 20, which will be explained later; a spiral body 22 with a pitch P, disposed on the outer periphery of the central column 21, spiraling from top to bottom, and having a gradually expanding structure that is narrow at the front end and wide at the rear end, and The top end is the inlet 24, and the bottom end is the outlet 25. The inlet 24 is connected to the aforementioned guide tube 17. A plurality of arc-shaped circumferential plates 26 cover and fix the outer periphery of the spiral body 22, so that the spiral body 22 forms a flow channel 27 and thereby constitutes a cylindrical spiral storage tank 20. A nozzle 28 is provided above the spiral storage tank 20 to push the fabric C lifted by the lifting wheel 16. The fabric C is pushed by the water flow in the nozzle 28 and guided by the guide tube 17 into the inlet 24. Then, the fabric C will move forward in the spiral storage tank 20 along the flow channel 27 formed by the spiral body 22 and finally flow out through the outlet 25 to perform swirling dyeing of the fabric C.

[0031] In the spiral storage trough 20 structure of the present invention, the arc-shaped surrounding plate 26 may have one or more maintenance holes 261, as shown in the figure. Figure 4A As shown; the maintenance hole 261 can also serve as an overflow hole, allowing the dye liquor contained in the fabric passing through the spiral body 22 to flow out of the spiral fabric storage tank 20 through the maintenance hole 261. Simultaneously, when the spiral fabric storage tank 20 is being maintained, the maintenance hole 261 can also serve as a spray hole for the washing liquid used to clean the spiral fabric storage tank 20. This embodiment further includes a platform 40 disposed below the spiral fabric storage tank 20, with a plurality of mesh holes 41 on the platform surface and four guide wheels 42 on the periphery of the platform 40. The body 10 contains... The lower end is further provided with two sets of tracks (not shown) corresponding to the guide wheel 42. When the spiral storage groove 20 inside the torso 10 needs adjustment or maintenance, the user can easily push the spiral storage groove 20 out of the torso 10 using these tracks, thus saving time and effort in maintenance work. In this invention, the spiral body 22 is composed of more than N plates 30, where N>3, and the spiral body 22, in conjunction with the tapered outer diameter of the inverted cone central column 21, causes the width of the spiral body 22 to gradually increase spirally from top to bottom with the height difference, as shown in the figure. Figure 6 and 4BAs shown, in this embodiment, there are 5 plates 30. The width of the first plate 30a adjacent to the inlet 24 is W1, the width of the second plate 30b connected to the first plate 30a is W2, the width of the third plate 30c is W3, the width of the fourth plate 30d is W4, and the width of the fifth plate 30e adjacent to the outlet 25 is W5. W5 > W4 > W3 > W2 > W1. Therefore, the spiral structure 22 will make the flow channel 27 gradually widen in a spiral rotation.

[0032] The spiral fabric storage trough 20 of the present invention further includes a receiving groove 50, the structure of which is as follows: Figures 4C-4D As shown, the spiral storage tank 20 is positioned on the side of the spiral storage tank 20, relative to the outlet 25, to receive the fabric output from the outlet 25. Therefore, after the fabric C enters the inlet 24, it will travel along the flow channel 27 formed by the spiral body 22 in the spiral storage tank 20 constructed between the central column 21 and the arc-shaped partition 26, and finally flow out of the receiving tank 50 through the outlet 25 for the swirling dyeing of the fabric C.

[0033] The spiral body 22 structure of the present invention, as follows: Figure 4E As shown, in this embodiment, the spiral 22 has N plates 30. One or more plates 30 can be selected as needed and further provided with a sandwich structure 35. The sandwich structure 35 is located at a predetermined position of the plate 30. It forms a sandwich space 36 with the plate 30 by a clamping plate 351. A plurality of perforations 361 are provided on the sandwich space 36, and a water inlet 37 is provided on one side of the sandwich space 36 so that water enters the sandwich space 36 through the water inlet 37 and overflows from the perforation 361.

[0034] In this invention, the spiral 22 is composed of N or more plates 30, where N > 3. In this embodiment, the number of plates 30 is 5, wherein the first plate 30a to the fifth plate 30e are as follows: Figures 5-6As shown, each plate 30 has a circular hole 31 in the middle that mates with the central post, and the outer periphery of each plate 30 is a circular edge 32. The plate 30 is radially cut from the circular hole 31 to the circular edge 32, forming a first cut edge 33 and a corresponding second cut edge 34 in the radial direction. These first cut edges 33 and second cut edges 34 are staggered vertically along the axial extension of the central post 21, forming a pitch P with a height difference. This allows the first to fifth plates to... The pitches P1 and P5 increase sequentially from top to bottom, i.e., pitch P1 < pitch P2 < pitch P3 < pitch P4 < pitch P5; thereby connecting and fixing the plates 30 to each other and to the central column 21, that is, connecting the second cut edge 34 of the previous plate to the first cut edge 33 of the next plate, for example, connecting the second cut edge 34a of the first plate 30a to the first cut edge 33b of the second plate 30b, and so on, thus forming a spiral body 22 that gradually opens from top to bottom.

[0035] In this invention, the ratio of the width of the second cut edge 34 at the bottom of each plate 30 to the width of the adjacent first cut edge 33 at the top must be greater than 1. This width ratio is designed and adjusted based on factors such as the type of fabric, the height of the spiral 22, and the inverted cone angle θ of the central column 21. A width ratio between 1.1 and 1.4 is preferred. This process is repeated to ensure that the width of the spiral 22 gradually expands from top to bottom. Furthermore, the ratio of the pitch (e.g., P2) of the lower plate (e.g., 30b) to the pitch (e.g., P1) of the adjacent upper plate (e.g., 30a) must also be greater than 1. The design is adjusted according to the type of fabric and the height of the spiral 22, with a pitch ratio between 1.1 and 1.4 being preferred, but not limited to this. Thus, the spiral 22 gradually widens from top to bottom, while the pitch P gradually increases from top to bottom. The two complement each other, resulting in a synergistic effect of 1+1>2. Furthermore, as the spiral 22 gradually increases in volume from top to bottom, the water flow gradually slows down due to the combined effect of the widening and heightening of the flow channel. This water flow further promotes the complete expansion and full saturation of the fabric within the flow channel, thereby achieving a smooth circulation of the fabric. Figure 7 The diagram illustrates the movement of fabric C in a spiral fabric storage tank. Fabric C enters the spiral fabric storage tank 20 through inlet 24. Due to the high-speed water flow from nozzle 28, and the fact that the central column 21 of the inverted cone is larger at the top and smaller at the bottom, the width of the first plate is narrower, while the width of the Nth plate is wider. Therefore, the water flow is faster at the upper end of the spiral fabric storage tank 20, and fabric C moves almost in a straight line. At the lower end of the spiral fabric storage tank 20, the water flow gradually slows down as the volume of the flow channel gradually increases. Thus, fabric C will achieve full stretching and thorough dyeing near the outlet 25.

[0036] The present invention, "Spiral Fabric Storage Tank Structure of a Dyeing Machine," combines a central column 21 of an inverted cone and a spiral body 22 extending downwards to form a spiral fabric storage tank 20 structure. The width of the spiral body 22 gradually expands from top to bottom, and its pitch P gradually widens from top to bottom. As the volume of the flow channel 27 gradually increases, the water flow velocity gradually slows down under the combined effect of the widening and heightening of the flow channel 27. The fabric C is carried by the water flow and rotates along the spiral body 22, allowing the fabric C to fully extend in the flow channel 27, thereby achieving a thorough dyeing effect. Since the present invention can solve the problem of smooth circulation of the fabric C in the spiral fabric storage tank 20 without the need for a fabric placement device, the present invention also has the benefits of reducing equipment costs and energy consumption.

[0037] The above description is illustrative only and not restrictive of the present invention. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the claims, and all such modifications, variations or equivalents will fall within the protection scope of the present invention.
