Description
Technical Field
[0001] This utility model relates to the field of textile machinery technology, and in particular, to a material feeding machine for car window sunshade curtains. Background Technology
[0002] A sunshade curtain fabric unwinding machine is an automated mechanical device for winding sunshade curtains. During operation, a taut tensioning strap presses down on the sunshade curtain roll to increase friction between the strap and the curtain, thereby improving the stability of the roll during rotation. However, in actual production, as the curtain roll is released, its diameter gradually decreases, leading to reduced friction between the tensioning strap and the curtain, making it difficult to maintain continuous and stable rotation.
[0003] To address the aforementioned issues, Chinese patent CN214652376U discloses a fabric guiding machine. When the sliding block moves the piston shaft end of the pendulum cylinder on the track plate, it changes the position of the pendulum cylinder against the rocker arm, thereby altering the effect of the pendulum cylinder against the rocker arm and adjusting the friction between the elastic band and the nonwoven fabric roll on the core rod. This solution partially solves the problem of reduced friction caused by a smaller fabric roll diameter. However, during the operation of the rocker arm device, as the position of the elastic band changes, the position and direction of the force exerted by the elastic band on the fabric roll also change. This makes it difficult to control the squeezing force of the elastic band on the fabric roll, thus affecting the stable rotation of the roll. Utility Model Content
[0004] The technical problem to be solved by this utility model is that in the prior art, the position and direction of the force exerted by the elastic band on the sunshade roller will change during the deflection process, which is not conducive to controlling the squeezing force on the sunshade roller and makes it difficult to ensure the stable rotation of the sunshade roller. Based on this, this utility model provides a car window sunshade curtain fabric pouring machine that can promote the stable rotation of the sunshade roller.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a car window sunshade curtain fabric feeding machine, including a frame and a sunshade curtain roll rotatably mounted on the frame, and further including a support component movably disposed below the sunshade curtain roll along the longitudinal direction and a drive component for driving the support component to move. The support component includes a movable frame, a driving wheel and a driven wheel rotatably mounted on the movable frame, a drive motor for driving the driving wheel to rotate, and a belt sleeved on the outside of the driving wheel and the driven wheel. The movable frame has an inverted triangular plate-shaped structure. The driving wheel is installed at the bottom of the movable frame. There are two driven wheels, which are installed at the top of the movable frame and symmetrically arranged about the line connecting the sunshade curtain roll and the driving wheel. An arc-shaped clearance groove is opened at the middle position of the top of the movable frame. The drive component drives the movable frame to move.
[0006] Furthermore, the body of the drive motor is fixedly mounted on the movable frame, and the drive wheel is fixedly connected to the output shaft of the drive motor.
[0007] Furthermore, bearings are provided at the connection points between the central shaft of the driving wheel and the central shaft of the driven wheel and the movable frame.
[0008] Furthermore, the frame includes a base and two support plates, which are symmetrically arranged on both sides of the base, and the sunshade roller is rotatably mounted between the two support plates.
[0009] Furthermore, the drive assembly includes a telescopic member, a lead screw, and a power structure. The telescopic member is installed between the movable frame and the base. The lead screw is rotatably connected to the base. The upper end of the lead screw is threadedly connected to the movable frame. The power structure is used to drive the lead screw to rotate.
[0010] Furthermore, the telescopic component includes a fixed sleeve and a movable rod. The fixed sleeve is vertically fixedly connected to the base, and the movable rod is slidably inserted into the fixed sleeve. The upper end of the movable rod is fixedly connected to the movable frame.
[0011] Furthermore, there are two telescopic members, which are arranged on opposite sides of the movable frame.
[0012] Furthermore, the power structure includes a lead screw motor mounted on the base, a driving gear mounted on the output shaft of the lead screw motor, and a driven gear mounted on the lead screw, wherein the driven gear meshes with the driving gear.
[0013] Furthermore, a semi-circular notch is provided on the upper surface of both support plates, and the two ends of the central axis of the sunshade roller are respectively placed on the semi-circular notch. A pressure plate is detachably installed on the top of both support plates, and a notch is provided on the lower surface of the pressure plate to cooperate with the semi-circular notch. The notch and the semi-circular notch together form a mounting hole, and the central axis of the sunshade roller rotatably passes through the mounting hole.
[0014] Furthermore, both ends of the central axis of the sunshade roller are provided with flanges protruding radially outward, and the two flanges respectively abut against the outer side of the support plate.
[0015] The beneficial effects of this utility model are: the car window sunshade curtain fabric feeding machine provided by this utility model has an upward movement of the supporting component under the action of the driving component, which causes the belt to squeeze the bottom of the sunshade curtain roll. As the belt moves upward with the diameter of the sunshade curtain roll decreasing, the pressure point of the sunshade curtain roll being squeezed by the belt remains constant, and the force on the sunshade curtain roll is easy to control, thereby ensuring the stable rotation of the sunshade curtain roll.

[0023] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0024] Please see Figures 1-5 This utility model provides a car window sunshade fabric unloading machine, including a frame 10, a sunshade roll 20 rotatably mounted on the frame 10, a support component 30 longitudinally movably disposed below the sunshade roll 20, and a drive component 40 for driving the support component 30. In use, the sunshade roll 20 is rotatably mounted on the frame 10, and the drive component 40 drives the support component 30 to move upward, so that the support component 30 abuts against the bottom of the sunshade roll 20. Thus, during the unloading process of the sunshade roll 20, the sunshade roll 20 will always be subject to the resistance applied by the support component 30, which can effectively prevent the sunshade roll 20 from reversing or over-rotating, and ensure the continuous and stable rotation of the sunshade roll.
[0025] Please see Figure 3 The frame 10 includes a base 11 and support plates 12. The base 11 is placed on a supporting plane (e.g., a factory floor) to support the entire unloading machine. Two support plates 12 are symmetrically arranged on both sides of the base 11. A sunshade roller 20 is rotatably mounted between the two support plates 12. Specifically, each support plate 12 has a semi-circular notch 121 on its upper surface. The two ends of the central axis of the sunshade roller 20 rest on the semi-circular notch 121. A pressure plate 122 is detachably mounted on the top of each support plate 12. A notch 1221 that mates with the semi-circular notch 121 is formed on the lower surface of the pressure plate 122. The notch 1221 and the semi-circular notch 121 together form a mounting hole (not shown in the figure). The central axis of the sunshade roller 20 rotatably passes through the mounting hole. In one specific embodiment, the pressure plate 122 and the support plate 12 are detachably connected by bolts 123.
[0026] Both ends of the central axis of the sunshade roller 20 are provided with flanges 201 protruding radially outward. The two flanges 201 abut against the outer side of the support plate 12, thereby restricting the axial movement of the sunshade roller 20.
[0027] Please refer to it again. Figure 1 , Figure 5 The supporting assembly 30 includes a movable frame 31, a driving wheel 32 and a driven wheel 33 rotatably mounted on the movable frame 31, a drive motor 34 for driving the driving wheel 32 to rotate, and a belt 35 sleeved on the outside of the driving wheel 32 and the driven wheel 33.
[0028] The movable frame 31 is roughly in the shape of an inverted triangular plate. The driving wheel 32 is installed at the bottom of the movable frame 31. There are two driven wheels 33, which are installed at the top of the movable frame 31 and are symmetrically arranged about the line connecting the sunshade roller 20 and the driving wheel 32. The body of the drive motor 34 is fixedly installed on the movable frame 31. The driving wheel 32 is fixedly connected to the output shaft of the drive motor 34. An arc-shaped clearance groove 311 is provided at the middle position of the top of the movable frame 31. This clearance groove 311 can provide space for the belt 35 to be occupied due to deformation. In use, the drive assembly 40 drives the movable frame 31 to move upward or downward longitudinally. When the movable frame 31 moves upward, it will drive the belt 35 to move upward as well, so that the belt 35 abuts against the bottom of the sunshade roller 20. As the sunshade roller 20 continues to unroll, the diameter gradually decreases. The upward movement of the belt 35 can ensure that the belt 35 always abuts against the sunshade roller 20, and the abutment point is always directly below the sunshade roller 20, which ensures the constancy of the force point of the sunshade roller 20 and is conducive to the stable rotation of the sunshade roller 20.
[0029] Bearings are provided at the connection points between the central shaft of the driving wheel 32 and the central shaft of the driven wheel 33 and the movable frame 31, so as to provide support and reduce rotational friction.
[0030] The drive assembly 40 includes a telescopic member 41, a lead screw 42, and a power structure 43. The telescopic member 41 is installed between the movable frame 31 and the base 11 of the frame 10. The lead screw 42 is rotatably connected to the base 11 of the frame 10. The upper end of the lead screw 42 is threadedly connected to the movable frame 31. The power structure 43 is used to drive the lead screw 42 to rotate.
[0031] The telescopic component 41 includes a fixed sleeve 411 and a movable rod 412. The fixed sleeve 411 is vertically fixedly connected to the base 11, and the movable rod 412 is slidably inserted into the fixed sleeve 411. The upper end of the movable rod 412 is fixedly connected to the movable frame 31. In use, the lead screw 42 rotates, thereby driving the movable frame 31 to move up or down. The movable rod 412 slides within the fixed sleeve 411, thereby guiding the movement of the movable frame 31.
[0032] In this embodiment, there are two telescopic members 41, which are arranged on opposite sides of the movable frame 31. The two telescopic members 41 improve the stability of the movable frame 31 during movement.
[0033] The power structure 43 includes a lead screw motor 431 mounted on the base 11, a drive gear 432 mounted on the output shaft of the lead screw motor 431, and a driven gear 433 mounted on the lead screw 42. The driven gear 433 meshes with the drive gear 432. In use, the lead screw motor 431 rotates, thereby driving the drive gear 432 to rotate, which in turn drives the lead screw 42 to rotate under the drive of the driven gear 433, ultimately forcing the movable frame 31 to move up or down.
[0034] In addition, a bearing is installed between the lower end of the lead screw 42 and the base 11. The inner ring of the bearing is embedded in the base 11, and the outer ring of the bearing is nested outside the lead screw 42.
[0035] In this embodiment, the power structure 43 adopts a lead screw drive, which operates smoothly, responds sensitively, and is free from slippage, allowing for precise control of the moving distance of the movable frame 31 and improving its movement stability. In other embodiments not shown, the power structure 43 can also be directly composed of a motor, in which case the motor directly controls the rotation of the lead screw 42. Alternatively, the drive assembly 40 can be directly composed of a cylinder, in which case the cylinder directly controls the movement of the movable frame 31 during use.
[0036] The operation process of this utility model's car window sunshade curtain fabric feeding machine is as follows:
[0037] The sunshade roller 20 is rotatably mounted on two support plates 12 and limited by the pressure plate 122. Then, the screw motor 431 is started to drive the movable frame 31 to move upward, thereby driving the belt 35 to press against the bottom of the sunshade roller 20. At this time, the sunshade on the sunshade roller 20 is released under the drive of the external roller. At the same time, the belt 35 runs synchronously, which effectively avoids the sunshade 20 from reversing or rotating excessively without affecting the unrolling.
[0038] The car window sunshade fabric feeding machine provided by this utility model has a holding component 30 that moves upward under the action of the driving component 40, which causes the belt 35 to squeeze the bottom of the sunshade 20. As the belt 35 moves upward with the diameter of the sunshade 20 decreasing, the pressure point of the sunshade 20 by the belt 35 remains constant, and the force on the sunshade 20 is easy to control, thereby ensuring the stable rotation of the sunshade roll 20.
[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
