Description

Technical Field

[0001] The utility model relates to the technical field of dyeing, in particular to an automatic pressing structure for loose fiber dyeing. Background Art

[0002] In the prior art, a loose fiber dyeing machine comprises an outer cylinder, and a loose fiber cage is arranged inside the outer cylinder. The loose fiber cage comprises an inner net cylinder and an outer net cylinder. An annular cylinder bottom is connected between the lower ends of the inner and outer net cylinders, and a cage cover is arranged above the inner and outer net cylinders. An automatic locking mechanism for a loose fiber cage cover disclosed in the authorized publication number CN221192619U. During the dyeing process, when the volume of the loose fibers between the inner and outer net cylinders becomes smaller and precipitates downward, the cage cover will automatically descend under the gravity of the counterweight disk, overcoming the friction force on the outer tooth surface of the rack and the elastic force of the spring, and automatically lock when it can no longer descend, thus avoiding the situation that a gap is generated between the cage cover and the loose fibers in the inner and outer net cylinders.

[0003] However, the above structure only descends by relying on the gravity of the counterweight disk. Although it avoids the situation that a gap is generated between the cage cover and the loose fibers in the inner and outer net cylinders, due to the too small pressing force on the loose fibers, some of the loose fibers are relatively loose, and the dye liquor will smoothly pass through the loose part, resulting in uneven dyeing. Summary of the Utility Model

[0004] The utility model provides an automatic pressing structure for loose fiber dyeing to always press the loose fibers in order to solve the above technical deficiencies.

[0005] The utility model discloses an automatic pressing structure for loose fiber dyeing, which comprises an inner net cylinder, an outer net cylinder, an annular cylinder bottom, an annular counterweight, a fixing plate, a column body, a pressing plate, a fastener, a spring, a first lifting ring and a second lifting ring. An annular cylinder bottom is arranged between the lower ends of the inner net cylinder and the outer net cylinder. The space between the inner net cylinder and the outer net cylinder is filled with loose fibers. An annular counterweight is placed between the upper ends of the inner net cylinder and the outer net cylinder, and the annular counterweight presses on the upper side of the loose fibers. A fixing plate is arranged at the upper end of the inner net cylinder. A column body is vertically arranged on the fixing plate. An external thread is arranged on the outer side surface of the column body. A first through hole is arranged in the middle of the pressing plate. The pressing plate is sleeved on the column body through the first through hole. Springs are evenly arranged between the pressing plate and the annular counterweight. One end of each spring is fixed to the pressing plate, and the other end of each spring is fixed to the annular counterweight. A fastener is screwed on the column body, and the lower end of the fastener presses against the upper end surface of the pressing plate. Two second through holes are symmetrically arranged on the pressing plate with respect to the center of the column body. Threaded holes are arranged on the annular counterweight directly below the second through holes. A plug rod is arranged on the first lifting ring, and an external thread is arranged on the plug rod. The plug rod passes through the second through hole and is screwed into the threaded hole. A second lifting ring is arranged at the upper end of the column body.

[0006] The principle of the above technical solution is that the spring is compressed by the fastener pressing the pressing plate. The annular counterweight presses the loose fibers by its own gravity and the elastic force of the spring. When the loose fibers are dyed at high temperature, their volume becomes smaller and they settle downward. At this time, the annular counterweight moves downward, avoiding the situation of generating a gap between the annular counterweight and the loose fibers. At the same time, the elastic force of the spring is still transmitted to the annular counterweight, so as to always press the loose fibers. The functions of the first lifting ring and the second lifting ring are to facilitate hoisting.

[0007] In order to facilitate the worker to tighten the fastener by hand, a handle is provided on the side of the fastener. By means of the handle, the force arm is increased, so that the fastener can be tightened by hand.

[0008] An automatic pressing structure for loose fiber dyeing obtained by the present utility model has the beneficial effect that, through the settings of the pressing plate, the spring and the annular counterweight, when the loose fibers are dyed at high temperature and their volume becomes smaller and they settle downward, the annular counterweight moves downward, avoiding the situation of generating a gap between the annular counterweight and the loose fibers. At the same time, the elastic force of the spring is continuously transmitted to the annular counterweight, so as to always press the loose fibers. Brief Description of the Drawings

[0009] Figure 1 It is a schematic structural diagram of Embodiment 1 of the present utility model. Detailed Embodiment

[0010] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following describes in detail the specific embodiments, structures, features and their effects of the present utility model in combination with the accompanying drawings and preferred embodiments.

[0011] Embodiment 1:

[0012] As Figure 1As shown in the figure, the utility model discloses an automatic pressing structure for loose fiber dyeing, which includes an inner net cylinder 2, an outer net cylinder 3, an annular cylinder bottom 1, an annular counterweight 5, a fixing plate 14, a cylinder 10, a pressing plate 7, a fastener 12, a spring 6, a first lifting ring 9, and a second lifting ring 11. An annular cylinder bottom 1 is arranged between the lower ends of the inner net cylinder 2 and the outer net cylinder 3. The space between the inner net cylinder 2 and the outer net cylinder 3 is filled with loose fibers 4. An annular counterweight 5 is placed between the upper ends of the inner net cylinder 2 and the outer net cylinder 3, and the annular counterweight 5 presses on the upper side of the loose fibers 4. A fixing plate 14 is arranged at the upper end of the inner net cylinder 2. A cylinder 10 is vertically arranged on the fixing plate 14. An external thread is arranged on the outer side surface of the cylinder 10. A first through hole is arranged in the middle of the pressing plate 7. The pressing plate 7 is sleeved on the cylinder 10 through the first through hole. Springs 6 are evenly arranged between the pressing plate 7 and the annular counterweight 5. One end of each spring 6 is fixed to the pressing plate 7, and the other end of each spring 6 is fixed to the annular counterweight 5. A fastener 12 is screwed on the cylinder 10. A handle 13 is arranged on the side surface of the fastener 12. The lower end of the fastener 12 presses on the upper end surface of the pressing plate 7. Two second through holes are symmetrically arranged about the center of the cylinder 10 on the pressing plate 7. A threaded hole is arranged on the annular counterweight 5 directly below the second through holes. A plug rod 8 is arranged on the first lifting ring 9. An external thread is arranged on the plug rod 8. The plug rod 8 passes through the second through holes and is screwed into the threaded holes. A second lifting ring 11 is arranged at the upper end of the cylinder 10.

[0013] The principle of the above technical solution is that the pressing plate 7 is pressed by the fastener 12, so that the spring 6 is in a compressed state. The annular counterweight 5 presses the loose fibers 4 by its own gravity and the elastic force of the spring 6. When the loose fibers 4 are dyed at high temperature, their volume becomes smaller and they precipitate downward. At this time, the annular counterweight 5 moves downward, avoiding the situation of generating a gap between the annular counterweight 5 and the loose fibers 4. At the same time, the elastic force of the spring 6 is continuously transmitted to the annular counterweight 5, so as to always press the loose fibers 4. The functions of the first lifting ring 9 and the second lifting ring 11 are to facilitate hoisting.
