Description

Technical Field

[0001] The utility model relates to the technical field of cotton carding machines, in particular to a self-adjusting and leveling device of a cotton carding machine for color spinning. Background Art

[0002] The working principle of the carding machine is to open, comb and remove impurities from the cotton rolls sent from the previous process or the oily cotton layer supplied by the cotton box, so that all the curled cotton loops become basically straight single fibers. In the process, the broken seeds, impurities and short fibers left over from the cotton cleaning process are removed, and then cotton strips of a certain specification are integrated and stored in cotton tubes for use in the drawing process.

[0003] When a cotton carding machine produces cotton slivers, the thickness of the generated cotton slivers often varies due to the different thickness of the cotton roll layer input at the feeding end of the cotton carding machine, which is not conducive to the subsequent processing and production of the cotton slivers. In actual production, it is necessary to strictly control the thickness of the cotton roll layer input, and then unify the production specifications of the cotton slivers to improve the production quality of the cotton slivers. Therefore, we proposed a self-adjusting and leveling device for a cotton carding machine for color spinning to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a self-leveling device for a carding machine for color spinning.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A self-adjusting and leveling device of a carding machine for color spinning, comprising a carding machine, a platform fixedly mounted on the side of the carding machine, a cotton roll rack fixedly mounted on the platform, cotton rolls rotatably mounted between the cotton roll racks, a cotton material inlet is provided at the carding machine corresponding to the platform, a plurality of support rods are fixedly mounted between the platform and the carding machine, a sensing mechanism is mounted on the side of the platform, a support plate fixedly mounted on the side of the carding machine, and an adjustment mechanism is mounted on the support plate.

[0007] Preferably, a controller is installed on the carding machine.

[0008] Preferably, the sensing mechanism includes a column barrel, a slide groove, a resistor column and a slip ring, wherein the column barrel is fixedly mounted on the upper side of the platform, the slide groove is provided on the side of the column barrel, the resistor column is mounted on the inner side of the column barrel, and the slip ring is slidably sleeved on the outer side of the resistor column.

[0009] Preferably, insulating pads are provided between the upper and lower ends of the resistor column and the column tube, a number of ball bearings are installed on the inner side of the slip ring, a conductive carbon brush is installed on the bottom of the slip ring, the conductive carbon brush is in sliding contact with the resistor column, a lightweight floating plate is fixedly installed on the right side of the slip ring, the lightweight floating plate is in sliding contact with the slide groove, and wires are connected to the conductive carbon brush and the resistor column.

[0010] Preferably, a collar is fixedly mounted on the left side of the slip ring, a stabilizing rod is slidably connected to the inner side of the collar, and the stabilizing rod is fixedly mounted on the inner wall of the column.

[0011] Preferably, the adjustment mechanism includes an electric telescopic rod, a mounting plate and a pressure roller, the electric telescopic rod is fixedly mounted on the bottom of the support plate, the mounting plate is fixedly mounted on the output end of the electric telescopic rod, and the pressure roller is rotatably mounted on the bottom of the mounting plate.

[0012] Preferably, two sliding rods are symmetrically fixedly mounted on the upper side of the mounting plate, and the upper ends of the sliding rods slide through to the upper side of the supporting plate.

[0013] In the utility model, the self-adjusting and leveling device of the cotton carding machine for color spinning is provided with an induction mechanism. When the cotton roll layer is input into the cotton carding machine from the cotton material inlet on the platform, the light floating plate in the induction mechanism is placed on the upper side of the cotton roll layer. The distance between the bottom of the light floating plate and the platform is the thickness of the cotton roll layer. When the thickness of the cotton roll layer changes, the light floating plate will drive the slip ring to slide on the resistance column, and the conductive carbon brush will also slide on the resistance column at the same time. Since the conductive carbon brush is connected with a wire, the effective resistance value connected to the circuit will indirectly change with the sliding of the conductive carbon brush on the resistance column. The controller can obtain the effective on-resistance value on the resistor column through the current value in the sensing mechanism according to the program calculation. It is known that the effective resistance of the resistor column is proportional to the conduction length, so the on-resistance length can be calculated, plus the fixed thickness of the insulating pad and the bottom of the column, and finally the fixed distance between the conduction carbon brush and the bottom of the lightweight floating plate, to obtain the distance between the bottom of the lightweight floating plate and the platform, that is, the thickness of the cotton roll layer. The above measurement method adopts indirect circuit calculation measurement, which is accurate, timely and sensitive, and can monitor the thickness value input of the cotton roll layer in real time.

[0014] In the utility model, a self-adjusting and leveling device of a cotton carding machine for color spinning is described. Through the setting of an adjustment mechanism, a controller timely adjusts the extension and retraction of an electric telescopic rod according to a set thickness value. When the electric telescopic rod is extended, it drives the pressure roller below to move downward, thereby reducing the thickness of the cotton roll layer. When the electric telescopic rod is contracted, the thickness of the cotton roll layer is increased, thereby real-time adjusting the thickness of the cotton roll layer entering the cotton carding machine.

[0015] The utility model has a reasonable design and adopts an indirect circuit calculation and measurement method through the setting of the sensing mechanism. It has the characteristics of accuracy, timely response and sensitivity. It can monitor the thickness value of the cotton roll layer input in real time, and cooperate with the adjustment mechanism to adjust the thickness of the cotton roll layer entering the carding machine in real time, thereby ensuring the uniformity of the cotton roll layer input thickness, thereby improving the uniformity of the cotton strip production of the carding machine.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A self-adjusting and leveling device of a carding machine for color spinning comprises a carding machine 1, a platform 3 is fixedly installed on the side of the carding machine 1, a cotton roll rack 6 is fixedly installed on the platform 3, and a cotton roll 7 is rotatably installed between the cotton roll racks 6. A cotton material inlet 5 is arranged at the carding machine 1 corresponding to the platform 3, a plurality of support rods 4 are fixedly installed between the platform 3 and the carding machine 1, a sensing mechanism 8 is installed on the side of the platform 3, a support plate 10 is fixedly installed on the side of the carding machine 1, an adjusting mechanism 9 is installed on the support plate 10, and a controller 2 is installed on the carding machine 1.

[0022] In this embodiment, the sensing mechanism 8 includes a column barrel 81, a slide groove 82, a resistor column 83 and a slip ring 85. A sleeve ring 87 is fixedly installed on the left side of the slip ring 85. A stabilizing rod 88 is slidably connected to the inner side of the sleeve ring 87. The stabilizing rod 88 is fixedly installed on the inner wall of the column barrel 81. The column barrel 81 is fixedly installed on the upper side of the platform 3. The resistor column 83 is installed on the inner side of the column barrel 81. The slip ring 85 is slidably sleeved on the outer side of the resistor column 83. A lightweight floating plate 86 is fixedly installed on the right side of the slip ring 85. Insulating pads 84 are provided between the upper and lower ends of the resistor column 83 and the column barrel 81. The slide groove 82 is opened on the side of the column barrel 81. A plurality of ball bearings are installed on the inner side of the slip ring 85. A conducting carbon brush 89 is installed at the bottom of the slip ring 85. The conducting carbon brush 89 is in sliding contact with the resistor column 83. The lightweight floating plate 86 is in sliding contact with the slide groove 82. Wires 810 are connected to the conducting carbon brush 89 and the resistor column 83.

[0023] Through the above structure, the setting of the ring 87 increases the sliding support points of the slip ring 85. When the slip ring 85 slides on the resistor column 83, the ring 87 slides on the stabilizing rod 88 at the same time, which increases the stability of the slip ring 85 when it moves. At the same time, a number of balls are arranged on the inner side of the slip ring 85, which reduces the friction resistance of the slip ring 85 when it slides, improves the sliding sensitivity, and thus improves the sensing sensitivity of the sensing mechanism 8.

[0024] In this embodiment, the adjustment mechanism 9 includes an electric telescopic rod 91, a mounting plate 92 and a pressure roller 94. The mounting plate 92 is fixedly mounted on the output end of the electric telescopic rod 91, the electric telescopic rod 91 is fixedly mounted on the bottom of the support plate 10, the pressure roller 94 is rotatably mounted on the bottom of the mounting plate 92, and two sliding rods 93 are symmetrically fixedly mounted on the upper side of the mounting plate 92, and the upper end of the sliding rod 93 slides through to the upper side of the support plate 10.

[0025] Through the above structure, the sliding rods 93 are symmetrically installed on both sides of the mounting plate 92. When the mounting plate 92 moves up and down driven by the electric telescopic rod 91, the sliding rods 93 also slide between the support plate 10, thereby ensuring the stability of the mounting plate 92, and then ensuring the stable working performance of the pressure roller 94, and further improving the stable and uniform ability of the pressure roller 94 to control the thickness of the cotton roll layer.

[0026] In the utility model, when in use, the power of the sensing mechanism 8 and the regulating mechanism 9 is connected through the controller 2, and the input control thickness of the cotton roll layer is input into the controller 2. When the cotton roll layer is input into the cotton combing machine 1 from the cotton material inlet 5 on the platform 3, the light floating plate 86 in the sensing mechanism 8 is placed on the upper side of the cotton roll layer, and the distance between the bottom of the light floating plate 86 and the platform 3 is the thickness of the cotton roll layer. When the thickness of the cotton roll layer changes, the light floating plate 86 will drive the slip ring to slide on the resistor column 83, and the conductive carbon brush 89 will also slide on the resistor column 83 at the same time. Since the conductive carbon brush 89 is connected to the conductive carbon brush 89, the effective resistance value connected to the circuit is indirectly changed as the conductive carbon brush 89 slides on the resistor column 83. The controller 2 can obtain the effective conductive resistance value on the resistor column 83 through the current value in the sensing mechanism 8 according to the program calculation. It is known that the effective resistance of the resistor column 83 is related to the conductive carbon brush 89. The length is proportional, then the conduction resistance length can be calculated, plus the fixed thickness of the insulating pad 84 and the bottom of the column 81, and finally the fixed distance between the conduction carbon brush 89 and the bottom of the light floating plate 86. The controller can calculate the distance between the bottom of the light floating plate 86 and the platform 3, that is, the thickness of the cotton roll layer. The above measurement method adopts an indirect circuit calculation measurement method, which is accurate, timely and sensitive, and can monitor the input thickness value of the cotton roll layer in real time; the controller 2 compares the real-time thickness of the surface roll layer measured by the sensing mechanism 8 with the input control thickness of the set cotton roll layer. When the thickness is thicker, when the electric telescopic rod 91 is started to extend, it drives the pressure roller 94 below to move downward, thereby reducing the thickness of the cotton roll layer; when the thickness is thinner, the electric telescopic rod 91 contracts, driving the pressure roller 94 to float, thereby increasing the thickness of the cotton roll layer. The above is the working process and principle of the utility model. The sensing mechanism 8 provided in the utility model adopts an indirect circuit calculation and measurement method, which is accurate, timely and sensitive. It can monitor the thickness value of the cotton roll layer input in real time, and cooperate with the adjustment mechanism 9 to adjust the thickness of the cotton roll layer entering the carding machine 1 in real time, thereby ensuring the uniformity of the cotton roll layer input thickness, thereby improving the uniformity of the cotton strip production of the carding machine 1.
