Description

Technical Field

[0001] The present invention belongs to the technical field of automatic discharging and weighing devices for dyes, and particularly relates to a powder dye discharging device with an anti-accumulation function. Background Art

[0002] At present, most dyeing processes in dyeing factories are such that process personnel issue a material list according to the formula, and then go to the material storage to weigh out the dyes. Each dye is weighed manually by an electronic balance and then enters production. If color difference occurs during the production process, the dye formula in the dye vat is adjusted. In this way, there are often problems such as color difference caused by inaccurate manual weighing, and even taking the wrong dye, resulting in serious economic losses. Since the powdered dye is weighed spoon by spoon manually, the whole process is purely manual, cumbersome, and the dye often spills out, causing waste and polluting the working environment. The weighing accuracy of the whole operation process is not high, the repeatability is poor, the efficiency is low, and the waste is serious.

[0003] At present, some manufacturers have also adopted an automatic weighing system. For example, the invention patent with the publication number of "CN103274232B" discloses a powdered dye feeding device, which sets a spiral discharging mechanism (composed of a spiral conveying rod, a feeding front end cover, a feeding rear end cover, and a rotary dialing manipulator) at the bottom of the dye tank. It discharges materials through a large screw rod to control the dye weighing, and it is very difficult to accurately control the weighing amount in this way.

[0004] In addition, during the dye feeding process, the powdered dye around the spiral conveying rod is continuously discharged from the dye tank. Since the powdered dye itself has a certain degree of cohesion, the powdered dye above the spiral conveying rod may agglomerate and stay in place without falling or fall untimely, resulting in unstable discharging, and further affecting the accuracy of dye weighing. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a powder dye discharging device with an anti-accumulation function.

[0006] The present invention is realized through the following technical solutions:

[0007] A powder dye discharging device with an anti-accumulation function includes a discharging front end cover, a spiral discharging shaft, a discharging port cover, a rotary discharging sleeve, a driving cylinder for driving the rotary discharging sleeve, and a disturbing wheel;

[0008] The discharging front end cover is arranged on the front side of the material tank;

[0009] The spiral discharging shaft is horizontally arranged in the material tank. The front section of the spiral discharging shaft is placed inside the discharging front end cover. When the spiral discharging shaft is driven to rotate, it will drive the dye in the material tank to move in the discharging direction;

[0010] The discharge port cover is arranged at the discharge port of the front discharge cover;

[0011] The rotating discharge sleeve is sleeved on the front discharge cover, and leakage holes are respectively arranged on the front discharge cover and the rotating discharge sleeve;

[0012] The driving cylinder is installed on the front discharge cover, and the action rod end of the driving cylinder is connected to the rotating discharge sleeve. The rotating discharge sleeve is driven by the driving cylinder to rotate on the circumference of the front discharge cover. When the leakage holes on the front discharge cover and the rotating discharge sleeve are opposite, a leakage channel is formed;

[0013] The disturbing wheel is rotatably installed above the spiral discharge shaft. The circumference of the disturbing wheel is provided with teeth, which are in transmission engagement with the spiral auger blades on the spiral discharge shaft. When the spiral discharge shaft is driven to rotate, it will drive the disturbing wheel to rotate, and then the disturbing wheel disturbs the dye in the material box to prevent material accumulation.

[0014] In the above technical solution, the disturbing wheel is provided with disturbing rods. The disturbing rods are vertically arranged on the disturbing wheel. A distance of 3 - 5 cm is left between the two ends of the disturbing rods and the inner wall of the material box. The number of disturbing rods is multiple, and they are arranged equidistantly along the circumference on the disturbing wheel.

[0015] In the above technical solution, the driving cylinder is installed on the front discharge cover through a bracket. The tail end of the cylinder body of the driving cylinder is hinged on the bracket, and the action rod end of the driving cylinder is hinged on the rotating discharge sleeve.

[0016] In the above technical solution, a limiting post is arranged on the front discharge cover, and a limiting long hole for cooperating with the limiting post is arranged on the rotating discharge sleeve. The limiting post is located in the limiting long hole, so as to limit the rotation angle of the rotating discharge sleeve.

[0017] In the above technical solution, a discharge net is arranged at the discharge port of the front discharge cover. The discharge net ensures the micro - discharge of the powdered dye and prevents the powdered dye from gushing out.

[0018] In the above technical solution, the discharge port cover is connected to the front discharge cover through a connecting arm. The front end of the connecting arm is fixedly connected to the discharge port cover, and the middle part of the connecting arm is connected to the front discharge cover through a rotating shaft, and a torsion spring is arranged at the rotating shaft. The torsion spring provides a closing force for the discharge port cover. When the tail end of the connecting arm is forced to move backward, the connecting arm rotates around the rotating shaft against the elastic force of the torsion spring, and the discharge port cover opens.

[0019] In the above technical solution, spiral auger blades are arranged on the spiral discharge shaft. When the spiral discharge shaft rotates, under the action of the spiral auger blades, the dye can be conveyed towards the discharge direction. A circle of evenly - arranged discharge blades is arranged along the circumference at the discharge end of the spiral discharge shaft.

[0020] In the above technical solution, the shape of a single uniform discharging blade is rectangular, and the number of uniform discharging blades is preferably 8 - 12.

[0021] In the above technical solution, the uniform discharging blades of the spiral discharging shaft are located above the material leakage through - hole on the front discharging cover, and the distance from the material leakage through - hole is preferably 2 - 5 mm. When the spiral discharging shaft rotates, the uniform discharging blades act on the dye above the material leakage through - hole, promoting the flow of the dye and enabling the dye to continuously and uniformly fall out from the material leakage through - hole, preventing the dye from accumulating.

[0022] In the above technical solution, there are multiple material leakage through - hole areas with different specifications on the front discharging cover.

[0023] In the above technical solution, a first larger - diameter material leakage through - hole area and a second smaller - diameter material leakage through - hole area are provided on the front discharging cover. By switching the material leakage through - hole on the rotating discharging sleeve to the first larger - diameter material leakage through - hole area or the second smaller - diameter material leakage through - hole area, different material leakage rates can be adjusted.

[0024] The advantages and beneficial effects of the present invention are as follows:

An openable discharging port cover is provided at the discharging port of the front discharging cover for large - dose discharging; moreover, a rotating discharging sleeve is provided on the front discharging cover, and material leakage through - holes are respectively provided on the front discharging cover and the rotating discharging sleeve. The rotating discharging sleeve is driven by a driving cylinder to rotate on the circumference of the front discharging cover. When the material leakage through - holes on the front discharging cover and the rotating discharging sleeve are opposite to each other, a material leakage channel is formed for small - dose discharging.

[0026] Multiple material leakage through - hole areas with different specifications are provided on the front discharging cover of the present invention. By switching the material leakage through - hole on the rotating discharging sleeve to different - specification material leakage through - hole areas, different discharging rates can be further adjusted.

[0037] In order to enable the personnel in the technical field to better understand the solution of the present invention, the technical solution of the present invention will be further described below in conjunction with specific embodiments.

[0038] Embodiment 1

[0039] See the attached Figures 1-3 , a powder dye discharging device with anti - material - accumulation function, includes a discharging front end cover 1, a spiral discharging shaft 2, a discharging port cover 3, a rotating discharging sleeve 4, a driving cylinder 5 for driving the rotating discharging sleeve and a disturbing wheel 6.

[0040] The discharging front end cover 1 is cylindrical and is arranged on the front side of the material box 0;

[0041] The spiral discharging shaft 2 is horizontally arranged in the material box 0. The front section of the spiral discharging shaft 2 is placed inside the discharging front end cover 1. When the spiral discharging shaft is driven to rotate, it will drive the dye in the material box to move in the discharging direction;

[0042] The discharging port cover 3 is arranged at the discharging port of the discharging front end cover 1;

[0043] The rotating discharging sleeve 4 is sleeved on the discharging front end cover 1. Leakage holes are respectively arranged on the discharging front end cover and the rotating discharging sleeve;

[0044] The driving cylinder 5 is installed on the front end cover of the discharge port. The end of the operating rod of the driving cylinder is connected to the rotary discharge sleeve 4. By driving the driving cylinder 5, the rotary discharge sleeve 4 is driven to rotate on the circumference of the front end cover of the discharge port. When the leakage through-hole on the front end cover of the discharge port and the leakage through-hole on the rotary discharge sleeve are opposite to each other, a leakage channel is formed, and the dye leaks out from the front end cover of the discharge port.

[0045] The disturbing wheel 6 is rotatably installed above the spiral discharge shaft 2. The circumference of the disturbing wheel 6 is provided with teeth, which are in transmission engagement with the spiral auger blades on the spiral discharge shaft 2. When the spiral discharge shaft 2 is driven to rotate, it will drive the disturbing wheel 6 to rotate. Furthermore, the disturbing wheel 6 disturbs the dye in the material box 0 to prevent material accumulation.

[0046] Furthermore, the disturbing wheel 6 is provided with disturbing material rods 6-1. The disturbing material rods 6-1 are vertically arranged on the disturbing wheel 6. The distances between the two ends of the disturbing material rods 6-1 and the inner wall of the material box 0 are left with a spacing of 3-5 cm. The number of the disturbing material rods 6-1 is multiple, and they are arranged at equal intervals along the circumference on the disturbing wheel 6.

[0047] Furthermore, the driving cylinder 5 is installed on the front end cover 1 of the discharge port through a bracket 7. The tail end of the cylinder body of the driving cylinder 5 is hinged on the bracket 7, and the end of the operating rod of the driving cylinder is hinged on the rotary discharge sleeve 4.

[0048] Furthermore, the front end cover 1 of the discharge port is provided with a limiting post 8, and a limiting long hole 9 for cooperating with the limiting post is arranged on the rotary discharge sleeve. The limiting post is located in the limiting long hole, so as to limit the rotation angle of the rotary discharge sleeve.

[0049] Furthermore, a discharge net 12 is arranged at the discharge port of the front end cover 1 of the discharge port. The discharge net 12 can ensure the micro-quantity discharge of the powdery dye and prevent the powdery dye from gushing out.

[0050] Furthermore, the discharge port cover 3 is connected to the front end cover of the discharge port through a connecting arm 10. The front end of the connecting arm 10 is fixedly connected to the discharge port cover. The middle part of the connecting arm is connected to the front end cover of the discharge port through a rotating shaft 11, and a torsion spring 13 is arranged at the rotating shaft. The torsion spring provides a closing force for the discharge port cover. When the tail end of the connecting arm 10 is stressed and moves backward, the connecting arm rotates around the rotating shaft 11 against the elastic force of the torsion spring, and the discharge port cover 3 opens.

[0051] Embodiment 2

[0052] On the basis of Embodiment 1, furthermore, this embodiment provides a spiral discharge shaft that is particularly suitable for the above-mentioned discharge device for powdery dye.

[0053] See attached Figures 4-5, a spiral auger blade is provided on the spiral discharge shaft. When the spiral discharge shaft rotates, under the action of the spiral auger blade, the dye can be conveyed towards the discharge direction. Along the circumference of the front end (i.e., the discharge end) of the spiral discharge shaft, a circle of evenly arranged uniform discharge blades is provided. The shape of a single uniform discharge blade is rectangular, and the number of uniform discharge blades is preferably 8 - 12.

[0054] Furthermore, the uniform discharge blades of the spiral discharge shaft are located above the leakage through holes on the discharge front end cover, and the distance from the leakage through holes is preferably 2 - 5 mm. When the spiral discharge shaft rotates, the uniform discharge blades act on the dye above the leakage through holes, promoting the flow of the dye and enabling the dye to continuously and evenly fall out from the leakage through holes, preventing the dye from accumulating.

[0055] Embodiment Three

[0056] Based on Embodiment One, further, multiple leakage through hole regions with different specifications can be provided on the discharge front end cover. For example, referring to the attached Figure 6 , a first larger-diameter leakage through hole region a1 and a second smaller-diameter leakage through hole region a2 are provided on the discharge front end cover. The diameter of a single leakage through hole in the first larger-diameter leakage through hole region is 4 mm, and the diameter of a single leakage through hole in the second smaller-diameter leakage through hole region is 2 mm. By switching the leakage through hole b on the rotating discharge sleeve to the first larger-diameter leakage through hole region a1 or the second smaller-diameter leakage through hole region a2, different leakage rates can be adjusted.

[0057] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right", etc. are used in the embodiments to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0058] Moreover, relative terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0059] The above provides an exemplary description of the present invention. It should be noted that without departing from the core of the present invention, any simple deformation, modification, or equivalent replacement that can be made by those skilled in the art without creative labor falls within the protection scope of the present invention.
