Description

Technical Field

[0001] This utility model belongs to the technical field of fabric equipment, specifically relating to a swing fabric device. Background Technology

[0002] For conveyor belt dryers, a swinging material distribution device is typically installed at the dryer inlet. This device evenly distributes the material onto the conveyor belt in a zigzag pattern, and then a leveling device smooths the material on the conveyor belt. Currently, swinging material distribution devices on the market are mainly divided into two categories based on their drive method: crank-rocker drive and screw-slider drive. Crank-rocker drive refers to a four-bar linkage mechanism with a crank and a rocker. Typically, the crank is the driving element and rotates at a constant speed, while the rocker is the driven element, oscillating back and forth at varying speeds, and the connecting rod performs a planar composite motion. In some crank-rocker mechanisms, the rocker is used as the driving element, converting its reciprocating oscillation into crank rotation. Because crank-rocker mechanisms have a quick-return characteristic, if used in a swinging material distribution device, it can cause differences in the velocity components of the distribution mechanism perpendicular to the wide conveyor, resulting in uneven material distribution height on the wide conveyor and uneven drying of subsequent materials entering the dryer.

[0003] Screw-slider drives convert rotary motion into linear motion or torque into reciprocating axial force. Ball screws, as precision components, are expensive and difficult to maintain. Furthermore, the oscillating fabric feeding device used in dryers requires a large oscillation angle and a wide oscillation range, thus demanding high rigidity from the screw. This increases design redundancy in the ball screw and raises costs. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. If not specifically indicated, the technical means used in the embodiments are conventional means familiar to those skilled in the art.

[0026] In the description of the present application, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0027] As shown in Figures 1-6 The present application discloses a swing material distributing device, which comprises a rack main body 4, a material distributing mechanism, a driving mechanism and a limiting mechanism installed on the rack main body 4. The inlet end of the material distributing mechanism is hingedly installed on the rack main body 4. The driving mechanism drives the outlet end of the material distributing mechanism to reciprocatingly swing horizontally above the inlet end of the conveyor belt. The material distributing mechanism uniformly distributes the material on the conveyor belt. In use, the position of the outlet end of the material distributing mechanism corresponds to the position of the inlet end of the conveyor belt, i.e. the outlet end of the material distributing mechanism is arranged above the inlet end of the conveyor belt, and the horizontal swinging range of the outlet end of the material distributing mechanism in the width direction of the conveyor belt does not exceed the width of the conveyor belt, so that the material from the outlet end of the material distributing mechanism falls into the inlet end of the conveyor belt. The material at the inlet end of the conveyor belt is flattened by the flattening device on the conveyor, and then the material at the inlet end of the conveyor belt is conveyed to the outlet end of the conveyor belt by the conveyor belt.

[0028] The driving mechanism comprises a driving chain 8, a driving part, an adjusting part and a movable tension sprocket 14. The driving chain 8 is tightly installed on the driving sprocket 7 and the driven sprocket 13. The driving sprocket 7 is driven by a motor. The driving sprocket 7 and the driven sprocket 13 are symmetrically arranged along the swing center line of the material distributing mechanism. The movable tension sprocket 14 is arranged between the driving sprocket 7 and the driven sprocket 13 and inside the driving chain 8. The fixed tension sprocket 15 is arranged between the driving sprocket 7 and the driven sprocket 13 and outside the driving chain 8, so that the driving chain 8 presents a "┤" shape.

[0029] The drive unit is fixedly installed at the lower end of the drive chain 8, and its upper end is fixedly connected to the lower part of the fabric dispensing end of the fabric mechanism. This causes the drive chain 8 to drive the drive unit to reciprocate horizontally, thereby causing the drive unit to drive the fabric dispensing end to reciprocate horizontally. The drive unit cooperates with the limiting mechanism, which restricts the drive unit's movement along an arc-shaped trajectory. The angular velocity of the drive unit is the same as the angular velocity of the fabric dispensing end. Because the drive unit moves along an arc-shaped trajectory, the chain length on the side where the drive chain 8 connects to the drive unit will change. An adjustment unit is provided, which drives the movable tension sprocket 14 to move (to...). Figure 4 Taking the arrangement of the movable tension sprocket 14 as an example, the movable tension sprocket 14 moves left or right to accommodate the chain length on the right side of the driving sprocket 7 and driven sprocket 13 in section 4, allowing the drive unit to perform arc-shaped trajectory movement, thus accommodating the change in the swing angle of the drive chain 8 as the material outlet end of the fabric mechanism changes. For ease of understanding, the chain length located on the side where the drive chain 8 connects to the drive unit refers to... Figure 4 The chain length on the right side of the driving sprocket 7 and the driven sprocket 13 is the sum of the chain length between the driving sprocket 7 and the adjusting slider 11 and the chain length between the driven sprocket 13 and the adjusting slider 11.

[0030] The drive unit and the limiting mechanism can cooperate in various ways, such as the pulley 10 cooperating with the arc-shaped track, the slider cooperating with the arc-shaped groove, or the T-shaped slider cooperating with the T-shaped arc-shaped groove. No particular method is limited here. Any structure that can enable the limiting mechanism to control the drive unit to move along the arc-shaped trajectory is within the protection scope of this application.

[0031] Furthermore, such as Figure 5 As shown, an adjustment through hole 19 is provided on the frame body 4, located on the swing center line of the fabric mechanism; the adjustment part includes an elastic element 12 and an adjustment slider 11. One end of the elastic element 12 is fixedly connected to the frame body 4, and the other end is fixedly connected to the lower part of the adjustment slider 11; the upper part of the adjustment slider 11 is slidably disposed in the adjustment through hole 19, and the movable tension sprocket 14 is installed on the top of the elastic element 12. The elastic element 12 here can be in the form of an elastic block, a rectangular spring, an elastic diaphragm, a helical spring, etc.

[0032] The working principle of the regulating unit is as follows: Figure 6As shown, when the drive unit is located at the center line of the fabric mechanism's swing, the elastic element 12 is in a compressed state and tends to elongate. When the drive unit moves from the center line of the fabric mechanism's swing to both sides, the length of the side of the drive chain 8 connected to the drive unit decreases. The adjusting slider 11 and the movable tension wheel 14 move to the right under the rebound force of the elastic element 12, thus putting the entire drive chain 8 in a tensioned state. When the drive unit moves from both sides towards the center line of the fabric mechanism's swing, the length of the side of the drive chain 8 connected to the drive unit increases. The movable tension wheel 14 and the adjusting slider 11 move to the left, the elastic element 12 is compressed, and the entire drive chain 8 is in a tensioned state. It should be noted that the elastic element 12 is always in a compressed state.

[0033] Furthermore, the drive unit includes a pulley 10 and a connecting column 9 connected to the drive chain 8. The pulley 10 is provided at the bottom of the connecting column 9, and the top of the connecting column 9 is connected to the discharge end of the fabric mechanism, specifically to the bottom surface of the discharge end of the fabric mechanism. The drive chain 8 is connected to the middle part of the connecting column 9.

[0034] The driving unit and the limiting mechanism can cooperate in the following way: the limiting mechanism includes a limiting track, the pulley 10 is slidably disposed on the limiting track, and the limiting track is an arc-shaped track corresponding to the movement trajectory of the driving unit.

[0035] Or, such as Figure 3 As shown, the limiting mechanism includes a limiting arc plate 6. In a preferred embodiment, the limiting arc plate 6 is provided with an arc-shaped track or an arc-shaped groove corresponding to the movement trajectory of the driving part, and the pulley 10 is slidably disposed on the limiting arc plate 6.

[0036] To prevent the drive chain 8 from falling off the drive sprocket 7 and the driven sprocket 13, a support plate 5 is provided below the drive chain 8 and on the frame body 4. The support plate 5 supports the drive chain.

[0037] Furthermore, the limiting mechanism is provided with second limiting blocks 17 at both ends, which restrict the movement position of the drive unit. A second position sensor 18 is provided beside the second limiting block 17 to detect the position of the drive unit. The extreme positions of the drive unit at both ends on the limiting mechanism are jointly limited by the second limiting blocks 17 and the second position sensor 18, ensuring safe operation of the device. The second position sensor 18 includes photoelectric encoders, magnetoelectric encoders, etc.

[0038] Further, the swing material distributing device comprises a control mechanism and a first motor 16, the material distributing mechanism is hinged to the frame body 4 at the inlet end, a first position sensor is arranged on the frame body 4, the first position sensor detects the position of the outlet end of the material distributing mechanism, the control mechanism controls the rotating speed of the first motor 16 according to the position of the outlet end of the material distributing mechanism, thereby controlling the rotating speed of the driving chain 8. The first position sensor comprises an optical encoder, a magneto-electric encoder and the like, and the optical encoder is recommended. Specifically, the first position sensor collects the position of the driving part, the control mechanism outputs different speeds according to the different positions of the driving part, so that the outlet end of the material distributing mechanism can uniformly distribute materials in the width direction of the conveyor (conveyor belt).

[0039] In order to make the control process of the control mechanism more simple, N detection points are uniformly arranged along the swing center line of the material distributing mechanism, N is a positive integer, the greater the value of N is, the more uniform the material distribution is, and 4N detection points are detected in one cycle of the back-and-forth swing of the material distributing mechanism, the first position sensor collects the position of each detection point and feeds back to the control mechanism, the control mechanism controls the first motor 16 to output corresponding rotating speeds according to different positions, and the speed of the corresponding driving chain 8 changes, thereby changing the swing speed of the material distributing mechanism. It should be noted that the control mechanism is internally provided with a control program which is set in advance, and different rotating speeds are output according to specific detection points. The control mechanism can be a control chip, a microprocessor or the like.

[0040] Further, the material distributing mechanism comprises a material distributing frame 1 and a conveying belt 2, the conveying belt 2 is arranged on the material distributing frame 1, and the conveying belt 2 is driven by a second motor 3.

[0041] A working process of the swing material distributing device: the inlet end of the material distributing mechanism is hingedly installed on the frame body 4, the outlet end of the material distributing mechanism is fixedly installed with a driving part at the lower part, the driving part is fixedly connected with a driving chain, the pulley of the driving part is slidingly and matchingly connected with a limiting track arranged on the frame body, the driving part is controlled to move in a circular arc track through the cooperation of the limiting track and the pulley, thereby driving the outlet end of the material distributing mechanism to swing back and forth horizontally, the first position sensor detects the position of the driving part in real time, and the control mechanism controls the rotating speed of the first motor 16 in real time according to the position of the driving part, thereby controlling the rotating speed of the driving chain 8, and thus the material distributing mechanism can uniformly distribute materials in the width direction of the conveyor belt.
