Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology and relates to an auxiliary tool for a calibration ring blower box. Background Technology

[0002] Patent CN202195891U points out that the ring blowing cooling device is mainly used for the production of porous fine denier and ultrafine denier fibers. Porous fine denier and ultrafine denier fibers have extremely high precision requirements for the ring blowing cooling device. In addition to ensuring the cleanliness of each layer of filter components, it is also necessary to ensure that the central axis of the internal ring blowing filter element coincides with the central axis of the component groove on the spinneret.

[0003] like Figure 5 and Figure 6 As shown, in the prior art, the annular blower box 1 is detachably fixed to the blower box base plate 22 of the blower box bracket. Specifically, two positioning pins 2 are fixed to the bottom of the annular blower box 1, and two through holes 23 are provided on the blower box base plate 22. During installation, the annular blower box 1 is placed on the blower box base plate 22 through the cooperation of the positioning pins 2 and the through holes 23, and then fixed by two nuts 24 threadedly connected to the positioning pins 2. However, the inner diameter of the through holes 23 is slightly larger than that of the positioning pins 2, which makes the position of the annular blower box on the blower box base plate not unique, and there will be slight deviations. It cannot be guaranteed that the central axis of the annular blower filter element in the annular blower box will coincide with the central axis of the component groove on the spinneret plate. To address this problem, the operator needs to correct the position of the annular blower box.

[0004] Patent CN205741321U discloses a novel and practical spinning bellows correction device. In use, the device's positioning block is aligned and adsorbed onto the lower end of the spinning assembly. The spinning bellows are then raised to their normal operating position. A correction measuring tool is used to measure whether the fine thread is centered in the hole, and the scale values ​​for the front, back, left, and right sides are measured to determine the deviation. If a deviation exists, the bellows base and slider are moved accordingly to correct the bellows. This method measures the actual positional deviation by visual reading, which is prone to inaccurate readings due to the limited space in the spinning area. Even a deviation of only 1-3 mm in the bellows can affect its performance, leading to a low success rate for subsequent corrections and a high probability of requiring secondary rework, thus doubling the time consumption.

[0005] Patent CN109811417A provides a multi-functional ring-blowing correction device that can achieve precise alignment between the center of the component and the center of the filter element. This patent uses a positioning device to emit a laser to locate the central axis of the component chamber. However, this method cannot obtain the horizontal coordinates of the central axis of the component, nor can it obtain the displacement vector that makes the central axis of the component coincide with the center of the filter element. Although the endpoint direction of the bellows correction is located, the actual distance that the bellows needs to be displaced is not clear. In actual operation, repeated adjustments by visual inspection are still required.

[0006] Therefore, it is of great significance to study an auxiliary tool for calibrating the ring blower box to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to solve the problems existing in the prior art and to provide an auxiliary tool for a calibration ring blower box.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An auxiliary tool for calibrating a ring blower box includes a telescopic positioner and a drive mechanism; the telescopic positioner includes a main support rod, a side support rod, a circular hoop I, an outer tube, and a positioning sensor;

[0010] The outer tube is placed vertically; the outer tube is a hollow round tube sealed at the top.

[0011] The number of main support rods is ≥3; one end of the main support rod is movably connected to the upper part of the outer tube;

[0012] The circular hoop I is fitted onto the outer tube and is slidably connected to the outer tube; the circular hoop I is located below the connection point between the main support rod and the outer tube;

[0013] The number of side support rods is the same as the number of main support rods; one end of each side support rod is movably connected to a main support rod, and they correspond one-to-one; the end of each side support rod that is not connected to a main support rod is movably connected to a circular hoop I; the ends of each main support rod that are not connected to the outer tube are on the same circle.

[0014] The drive mechanism is used to push the circular hoop I up and down; in the prior art, the inner diameter of the annular filter element is smaller than the inner diameter of the component groove; when the drive mechanism is not started, the circle where the end of all the main support rods is not connected to the outer pipe is denoted as circle A, and the diameter of circle A is smaller than the inner diameter of the annular filter element; when the drive mechanism is at its maximum range, the circle where the end of all the main support rods is not connected to the outer pipe is denoted as circle B, and the diameter of circle B is larger than the inner diameter of the component groove.

[0015] The positioning sensor is fixed to the top of the outer tube and is used to locate the horizontal coordinates of the center of the top of the outer tube.

[0016] The specific usage process is as follows: The upper part of the outer tube is inserted into the component slot. Then, the drive mechanism drives the circular hoop I to unfold the main support rod. Since the cross-section of the component slot is circular, the ends of all the main support rods that are not connected to the outer tube are always on the same circle. Therefore, during the unfolding process, the horizontal position of the outer tube is automatically adjusted. When all the main support rods are in contact with the inside of the component slot, the circle on which the ends of all the main support rods are not connected to the outer tube is equal to the inner diameter of the component slot. At this time, the central axis of the outer tube coincides with the central axis of the component slot, and the positioning sensor detects the horizontal coordinate of the central axis of the component slot. Similarly, the plane coordinates of one component slot and two annular blow filter elements are detected respectively (when detecting the plane coordinates of the annular blow filter elements, the end of the outer tube with the positioning sensor is inserted upside down into the annular blow filter element). Then, based on the measured plane coordinates of the two component slots and two annular blow filter elements, the annular blow box is moved so that the annular blow box is aligned with the spinneret.

[0017] As a preferred technical solution:

[0018] As described above, the auxiliary tool for calibrating the ring blower box includes a telescopic positioner with a crossbar. The crossbar is located below the circular hoop I and is fixedly connected to the circumference of the outer tube. When the upper part of the outer tube is inserted into the component slot, the crossbar is in close contact with the spinneret surface, which ensures that the outer tube remains vertical during insertion into the component slot. Similarly, when inserted into the ring blower filter element of the spinning box, the crossbar is in close contact with the upper surface of the ring blower box, which also ensures that the outer tube remains vertical during insertion into the ring blower filter element.

[0019] As described above, in an auxiliary tool for a correction ring blower box, the main support rods are evenly distributed around the circumference of the outer tube.

[0020] As described above, an auxiliary tool for a calibration ring blower box includes a circular hoop I made of iron and an outer tube made of non-magnetic metal. The drive mechanism includes a magnetic ball and a lifting bracket.

[0021] The lifting support is a vertical rod, and the upper end of the lifting support is fixedly connected to the magnetic ball. The upper end of the lifting support is inserted into the outer tube. The lifting support is used to drive the magnetic ball to move up and down inside the outer tube, thereby controlling the up and down movement of the circular hoop I.

[0022] As described above, an auxiliary tool for a correction ring blower box includes a telescopic locator, which further includes a circular hoop II. The circular hoop II is detachably fixed to the upper part of the outer tube (which can be threaded). One end of the main support rod is movably connected to the circular hoop II, thereby indirectly connecting to the upper part of the outer tube. The purpose of designing the circular hoop II is to facilitate the disassembly of the main support rod, the side support rod, and the circular hoop I, thereby facilitating maintenance.

[0023] As described above, the auxiliary tool for a calibration ring blower box includes two magnetic balls, two lifting brackets, and two telescopic positioners; the drive mechanism also includes a three-way pipe, a T-shaped rod, and an electric lifting rod.

[0024] The tee pipe includes a horizontal pipe and a vertical pipe; both ends of the horizontal pipe are fixedly connected to the lower end of the outer pipe of a telescopic positioner; a T-shaped rod is located inside the tee pipe, and the opposite ends of the T-shaped rod are fixedly connected to the lower end of a lifting bracket; the fixed end of the electric lifting rod is fixed inside the vertical pipe, and the telescopic end of the electric lifting rod is fixedly connected to the remaining end of the T-shaped rod; the electric lifting rod is used to drive the T-shaped rod to move up and down, thereby driving the two lifting brackets to move up and down; the inner diameter of the horizontal pipe is greater than the maximum range of the electric lifting rod.

[0025] The distance between the central axes of the outer tubes of the two telescopic positioners is equal to the distance between the central axes of the two component slots;

[0026] In this scheme, the horizontal coordinates of the central axis of two component slots or the central axis of two annular filter elements can be measured simultaneously.

[0027] As described above, the auxiliary tool for the calibration ring blower also includes a controller II, which is electrically connected to the electric lifting rod and is used to control the range of the electric lifting rod.

[0028] As described above, the auxiliary tool for the calibration ring blower also includes a display; the display is electrically connected to the positioning sensor, and the display is used to display the horizontal coordinates of the positioning sensor.

[0029] As described above, the auxiliary tool for the calibration ring blower also includes a moving mechanism and a controller I.

[0030] The moving mechanism is detachably and fixedly connected to the ring blower box; the moving mechanism is used to move the horizontal position of the ring blower box; the controller I is electrically connected to the moving mechanism and is used to control the moving mechanism to move the horizontal position of the ring blower box.

[0031] As described above, an auxiliary tool for calibrating a ring blower box includes two positioning pins fixed to the bottom of the ring blower box; two through holes are provided on the base plate of the blower box; during installation, the ring blower box is placed on the base plate of the blower box by the cooperation of the positioning pins and the through holes, and then the ring blower box is fixed by the threaded connection of two nuts to the positioning pins; the auxiliary tool for calibrating the ring blower box also includes a movable bracket and a positioning pin slot.

[0032] There are two positioning pin slots, with the openings of the positioning pin slots facing upwards; the top of the movable bracket is fixedly connected to the positioning pin slot, and the bottom of the movable bracket is fixedly connected to the moving mechanism; the movable bracket is used to control the distance between the positioning pin slot and the positioning pin; each of the two positioning pin slots is used to receive one positioning pin.

[0033] In practical use, first remove two nuts, move the moving mechanism and the movable bracket so that the positioning pin is inserted into the positioning pin slot, and then move the ring blower according to the four horizontal coordinates. After the ring blower is calibrated, the auxiliary tool for calibrating the ring blower can be quickly removed so that the production line can operate normally.

[0034] Beneficial effects:

[0035] 1. This utility model uses the telescopic positioning device to extend the main support rod and fit into the inner wall of the component groove and the ring blow filter element, so that the central axis of the outer tube automatically coincides with the central axis of the component groove and the ring blow filter element. Combined with the positioning sensor, the coordinates are accurately obtained, providing a reliable basis for calibration.

[0036] 2. This utility model uses a positioning sensor to directly obtain accurate coordinates to clarify the deviation, and the main support rod automatically unfolds to achieve rapid positioning without repeated adjustments, simplifying the operation process and reducing calibration time.
