Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing, in particular to an O-shaped cloth trough for a dyeing cylinder with an adjustable baffle. Background Art

[0002] The O-type dyeing vat is a new type of fabric printing and dyeing equipment with the advantage of water saving. It is composed of a vat body, a tower head, a fabric trough, etc. The vat body is a closed cylindrical structure with a horizontal axis and a fabric inlet on its side. The tower head is located above the vat body, and the tower head has a fabric circulation conveying mechanism and a spray pipe. The fabric trough is a C-shaped structure and is located inside the vat body. The fabric trough has an upper fabric inlet and a lower fabric outlet. The fabric inlet is connected to the outlet of the spray pipe, and the fabric outlet is connected to the inlet of the fabric circulation conveying mechanism.

[0003] Chinese patent CN217127762U discloses an eco-friendly and water-saving O-type dyeing vat, the working process of which is to twist the cloth into a rope shape, feed it into the vat from the cloth inlet, and then pass through the spray pipe, the cloth inlet and the cloth outlet in sequence under the action of the cloth circulation conveying mechanism, return to the vicinity of the cloth inlet, and then connect the head and tail of the cloth. The tower head allows the cloth to continuously pass through the spray position, so that the cloth is printed with color, and the cloth is straightened through a section of the tower head and passes through a very narrow spray pipe, while the rest of the cloth is relaxed and accommodated in the cloth groove in a reciprocatingly curved serpentine shape.

[0004] Ideally, the cloth in the cloth slot is always close to the lower wall, and there will be no multi-layer stacking. Otherwise, it will be entangled and cannot return to the cloth circulation conveying mechanism in a single strand state, so it is easy to get stuck when passing through the cloth circulation conveying mechanism. In the prior art, the width of the cloth inlet is often fixed. If the density of the cloth is relatively small, it will be piled up in the vertical plane after passing through the cloth inlet, and the structure is easy to collapse, resulting in abnormal stacking and entanglement, which is easy to hinder the continuous conveying of the cloth during circulation, which is not conducive to the normal printing and dyeing.

[0005] Therefore, it is necessary to improve the cloth groove structure to meet the safety requirements. Summary of the invention

[0006] The main purpose of the utility model is to provide an O-shaped cloth trough for dyeing vats with adjustable baffles, which can make the inlet width of the cloth trough adapt to the width of the cloth by using the baffle with variable turning angle, so that the cloth can be orderly distributed in a serpentine shape when falling to the lower part of the cloth trough, thereby ensuring the continuous cycle of printing and dyeing.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: an O-shaped cloth trough for dyeing vats with adjustable baffles, comprising a trough body, a baffle and a flip control mechanism;

[0008] The cross-section of the trough body is C-shaped. The trough body has a cloth inlet at the upper part and a cloth outlet at the lower part. The cloth inlet is a waist-shaped hole with a longer transverse dimension.

[0009] The baffle is rotatably connected inside the trough body, and the rotating shaft is located below the cloth inlet. The vertical length of the baffle is 50% - 70% of the height of the trough body.

[0010] The flipping control mechanism is arranged outside the trough body and controls the rotation angle of the baffle.

[0011] Specifically, the cross-section of the baffle is J-shaped. The baffle includes a flat part, a rear-bending part, and a support frame. The flat part is connected to the upper part of the rear-bending part and is rotatably connected inside the trough body. The rear-bending part bends away from the large cylindrical surface of the trough body. The support frame is composed of criss-crossed profiles and connects the flat part and the back of the rear-bending part.

[0012] Further, the flat part is rectangular. The baffle also includes four reinforcing strips. Three of the reinforcing strips are respectively located on the three sides of the flat part away from the rear-bending part, and one reinforcing strip is located on the side of the rear-bending part away from the flat part.

[0013] Further, the flipping control mechanism includes a cylinder, a first connecting rod, a transmission shaft, and several second connecting rods. The cylinder is rotatably connected to one side of the trough body. The transmission shaft is rotatably connected outside the trough body. The axis of the transmission shaft is parallel to the axis of the trough body. The two ends of the first connecting rod are respectively hinged to the end of the cylinder shaft of the cylinder and one end of the transmission shaft. Multiple swing blocks are provided in the middle of the transmission shaft. The two ends of each second connecting rod are respectively hinged to the end of the swing block and the support frame.

[0014] Further, the cloth trough includes a plurality of trough bodies arranged side by side. The axes of the plurality of trough bodies are collinear. Each trough body is provided with a baffle inside, and the transmission shaft drives the rotation of the multiple baffles simultaneously in the same way.

[0015] The beneficial effects of the technical solution of the present utility model are:

[0016] In the present utility model, a fabric falling channel with a variable width is formed between the baffle and the large cylindrical surface outside the trough body, and the width of the channel depends on the rotation angle of the baffle, that is, when the baffle droops, the width of the channel becomes larger, and when the baffle tilts upward, the width of the channel becomes smaller, so that it can adapt to the density of various fabrics. The length of the baffle cannot be too short, otherwise when the fabric passes through the above channel, the angle between the arc tangent plane of the trough body contacted by the fabric and the horizontal direction exceeds 45°. When the fabric is pressed, the structural instability is relatively high and the risk of collapse is relatively large. Therefore, the length of the baffle needs to make the fabric located within the lower 45° range of the large cylindrical surface of the trough body when it separates from the baffle. At this time, the upward support component force of the trough body on the fabric is greater than the lateral support component force, which can better avoid the problem of fabric collapse, enable the fabric to be orderly distributed in a snake-like state, and ensure the continuous progress of circular printing and dyeing.

[0026] The present utility model will be further described in detail below with reference to specific embodiments.

[0027] Embodiment:

[0028] As Figure 1 shown, a cloth trough for an O-shaped dyeing vat with an adjustable baffle of the present utility model includes a trough body 1, a baffle 2 and a flipping control mechanism 3.

[0029] As Figures 1 to 4As shown, the cross section of the trough body 1 is C-shaped, and the trough body 1 has a cloth inlet 11 at the top and a cloth outlet 12 at the bottom, and the cloth inlet 11 is a laterally long waist-shaped hole.

[0030] The cloth enters the tank 1 from the cloth inlet 11 in a horizontal reciprocating conveying mode, so it will present a serpentine state when it is accumulated at the lower part of the tank 1. The cloth leaves the tank 1 from the cloth outlet 12 by being pulled out, so the original serpentine state will become a linear state.

[0031] The baffle 2 is rotatably connected to the inside of the trough body 1 and the rotating shaft is located below the cloth inlet 11. The upper and lower lengths of the baffle 2 are 50% to 70% of the height of the trough body 1. The cross-section of the baffle 2 is J-shaped. The baffle 2 includes a plane portion 21, a rear bend portion 22, a support frame 23 and four reinforcement strips 24. The plane portion 21 is rectangular, and the plane portion 21 is connected to the upper part of the rear bend portion 22 and is rotatably connected to the trough body 1. The rear bend portion 22 is bent in a direction away from the large cylindrical surface of the trough body 1. The support frame 23 is composed of criss-crossed profiles and connects the plane portion 21 and the back of the rear bend portion 22. Three reinforcement strips 24 are respectively located on the three sides of the plane portion 21 away from the rear bend portion 22, and one reinforcement strip 24 is located on the side of the rear bend portion 22 away from the plane portion 21.

[0032] The smaller cylindrical surface on the inner side of the trough body 1 is the small cylindrical surface, and the larger cylindrical surface on the outer side is the large cylindrical surface. A cloth falling channel with variable width is formed between the baffle 2 and the large cylindrical surface outside the trough body 1, and the width of the channel depends on the turning angle of the baffle 2, that is, when the baffle 2 sags, the channel width becomes larger, and when the baffle 2 tilts up, the channel width becomes smaller, so that it can adapt to the density of various cloths (reflected in the approximate diameter of the cloth when it is in strands). The length of the baffle 2 cannot be too short, otherwise the angle between the arc section direction of the cloth contacting the trough body 1 and the horizontal direction exceeds 45° when passing through the above channel. When the cloth is piled up, the structural instability is high and the risk of collapse is relatively large. Therefore, the length of the baffle 2 needs to make the cloth be located within the lower 45° range of the large cylindrical surface of the trough body 1 when it is separated from the baffle 2. At this time, the upward support component of the cloth by the trough body 1 is greater than the lateral support component, which can better avoid the problem of cloth collapse, so that the cloth can be distributed in a serpentine state in an orderly manner, and ensure the continuous progress of cyclic printing and dyeing. In order to prevent the lower edge of the baffle 2 from hooking the fabric, the rear bend 22 is bent into an arc surface, so that the contact position between the rear bend 22 and the fabric is smooth. The support frame 23 and the reinforcement strip 24 are used to improve the structural rigidity of the baffle 2, prevent the baffle 2 from being twisted and deformed by the reaction force of the fabric, and ensure the stability of the channel width between the baffle 2 and the trough body 1.

[0033] like Figures 1 to 4As shown in the figure, an overturning control mechanism 3 for controlling the rotation angle of the control baffle 2 is provided outside the tank body 1. The overturning control mechanism 3 includes a cylinder 31, a first connecting rod 32, a transmission shaft 33 and a plurality of second connecting rods 34. The cylinder 31 is rotatably connected to one side of the tank body 1, and the transmission shaft 33 is rotatably connected outside the tank body 1. The axis of the transmission shaft 33 is parallel to the axis of the tank body 1. The two ends of the first connecting rod 32 are respectively hinged to the end of the cylinder shaft of the cylinder 31 and one end of the transmission shaft 33. A plurality of swing blocks 331 are provided in the middle of the transmission shaft 33. The two ends of each second connecting rod 33 are respectively hinged to the end of the swing block 331 and the support frame 23.

[0034] The first connecting rod 32, the transmission shaft 33 and the second connecting rod 34 constitute a transmission system, which transmits the telescopic action of the cylinder 31 into the rotational action of the baffle 2. The support frame 23 also provides a hinged position for the second connecting rod 34. In this embodiment, when the cylinder shaft of the cylinder 31 extends, the baffle 2 swings upward and the channel becomes narrower; on the contrary, the channel becomes wider, realizing the automatic control of the channel width.

[0035] As Figure 1 shown, the cloth trough includes two tank bodies 1 arranged side by side. The axes of the two tank bodies 1 are collinear, and the transmission shaft 33 drives the rotation of the two baffles 2 in the same way at the same time.

[0036] In this way, the volume of the cloth trough is doubled. Each of the two tank bodies 1 dyes a piece of cloth, and correspondingly, the entire O-shaped dyeing vat will also have two tower heads. And the two tank bodies 1 share a set of overturning control mechanism 3, saving parts. In practical applications, the number of tank bodies 1 is not limited to two. The number of baffles 2 is the same as the number of tank bodies 1. Therefore, each tank body 1 is provided with a baffle 2 inside, and all the baffles 2 are driven to rotate together by the transmission shaft 33.

[0037] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
