Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a pneumatic warping machine. Background Technology

[0002] Warping machines are key equipment in the textile industry used to wind yarn onto a drum in a specific pattern. Their core functional chambers provide uniform and tension-stable warp yarns for subsequent weaving processes.

[0003] When changing the drum on an existing warping machine, it is usually necessary to first fix the drive end, connect the assembly head on one side of the drum to the drive end of the warping machine through a keyway or flange, and tighten it with bolts. Then, assemble the other side of the drum onto the connector of the warping machine. During this process, because the drum is heavy, it is necessary to manually stabilize the drum and continuously adjust its position to align the assembly head with the connector to finally complete the installation of the drum.

[0004] However, changing the warping machine drum according to the above operation is not only time-consuming and laborious, but also poses safety hazards to operators and equipment if not operated properly. Utility Model Content

[0005] The purpose of this invention is to provide a pneumatic warping machine to solve the above-mentioned problems.

[0006] The technical solution of this utility model is implemented as follows:

[0007] This utility model provides a pneumatic warping machine, including a machine body on which a drum is mounted and driven to rotate via a drive end. A mounting base is also movable up and down on the machine body. A bracket is rotatably mounted on the mounting base and equipped with a motor for driving the bracket to rotate. Symmetrically arranged fasteners are hinged to one end of the bracket away from the mounting base, and a compression spring is fixed between the two fasteners. A cavity extending to the center is opened on the side of the drum away from the drive end of the machine body. The cavity spirals inward from the outside to the inside, and the fasteners slidably press against the inner wall of the cavity.

[0008] In one embodiment, the fastener includes a drive section and two force-applying sections. One end of the drive section is hinged to a bracket, and the two force-applying sections are respectively hinged to the two sides of the drive section away from the bracket. The other ends of the two force-applying sections extend in a direction away from each other and press against the inner wall of the cavity.

[0009] In one embodiment, a protrusion is fixed at one end of the force-applying section that abuts against the inner wall of the cavity. The protrusion is arc-shaped, and the orientation of the arc-shaped end of the protrusion is consistent with the path direction of the fastener as it spirals along the inner wall of the cavity.

[0010] In one embodiment, a telescopic member is fixed between the two drive sections, and the compression spring is telescopically sleeved on the outside of the telescopic member.

[0011] In one embodiment, the cavity located in the middle of the roller is provided with a ring-shaped groove, and the protrusion is slidably embedded in the groove.

[0012] In one embodiment, limiting members are fixed on the upper and lower sides of the drive section, which are used to limit the maximum swing amplitude of the force application section.

[0013] In one embodiment, a vertical guide rail is fixed on the body, and a slider is fixed at one end of the mounting base facing the vertical guide rail. The slider is slidably engaged with the vertical guide rail, allowing the mounting base to slide up and down along the vertical guide rail.

[0014] In one embodiment, the machine body is further provided with an electric telescopic rod, the telescopic end of which is fixed to the mounting base.

[0015] The advantages or beneficial effects of the above technical solutions include at least the following:

[0016] In this invention, during the entire installation process of the drum, the operator only needs to lower the mounting base, start the motor, and push the drum so that the fastener slides into the deep cavity. Then, the motor is stopped, the mounting base is raised, and the drum is connected to the drive end of the machine body. When connecting to the drive end, the fastener provides support for the drum. This not only eliminates the need for manual adjustment of components such as bolts and the steps of adjusting the drum position, but also greatly shortens the operation time for changing the drum, improves production efficiency, and reduces the labor intensity and possibility of misoperation for the operator.

[0028] Reference Figures 1-4A pneumatic warping machine includes a body 1, on which a drum 2 is mounted and driven to rotate via a drive end. A mounting base 3 is also movable vertically on the body 1. A bracket 4 is rotatably mounted on the mounting base 3 and equipped with a motor 5 for driving the bracket 4 to rotate. Symmetrically arranged fasteners 6 are hinged to the end of the bracket 4 away from the mounting base 3, and a compression spring 7 is fixed between the two fasteners 6. A cavity 8 extending to the center is formed on the side of the drum 2 away from the drive end of the body 1. This cavity 8 spirals inward from the outside to the inside. The fasteners 6 slidably press against the inner wall of the cavity 8. With this configuration, when mounting the drum 2, the mounting base 3 is first driven to slide downward. This causes the entire bracket 4 and fasteners 6 to move closer to the drum 2. At this point, the two fasteners 6 are slid into the cavity 8 opened in the drum 2. Then, the motor 5 is started to rotate the bracket 4 and fasteners 6. During this process, the end of the drum 2 furthest from the mounting base 3 is pushed towards the mounting base 3. As the bracket 4 rotates and the drum 2 slides, the fasteners 6 slide into the depth of the cavity 8 in a spiral motion. When the fasteners 6 reach the deepest point of the cavity 8, the motor 5 is stopped. Since the cavity 8 spirals inward from the outside, when the end of the fastener 6 slides inward along this gradually narrowing spiral cavity 8, it is squeezed inward by the inner wall of the cavity 8, compressing the spring 7. Initially, the two fasteners 6 tend to push outwards. When the fasteners 6 are forcibly pressed inwards, the compression spring 7 is further compressed. At this time, the reaction force generated by the compression spring 7 will continue to try to push the fasteners 6 outwards. However, due to the constraint of the inner wall of the cavity 8, this reaction force is eventually transformed into a radial clamping force on the central axis of the drum 2. Therefore, after the fasteners 6 slide into the cavity 8 of the drum 2, under the dual action of the reaction force of the compression spring 7 and the constraint of the inner wall of the cavity 8, the fasteners 6 will generate a strong and uniform radial clamping force towards the center of the drum 2 to firmly fix the drum 2 to the fasteners 6. Finally, the mounting base 3 is controlled to rise so that the drum 2 rises. The installation of drum 2 can be completed by aligning the centerline with the drive end of machine body 1 and connecting the other end of drum 2 to the drive end of machine body 1. During the installation process, the operator only needs to lower the mounting base 3, start the motor 5, and push the drum 2 so that the fastener 6 slides into the cavity 8. Then, stop the motor 5 and raise the mounting base 3. Then connect the drum 2 to the drive end of machine body 1. When connecting to the drive end, the fastener 6 provides support for the drum 2. This not only eliminates the need for manual adjustment of parts such as bolts and the steps of adjusting the position of drum 2, but also greatly shortens the operation time for replacing drum 2, improves production efficiency, and reduces the labor intensity and possibility of misoperation of operators.

[0029] In one specific embodiment, when it is necessary to disassemble the drum 2, first disconnect the connection between the drive end of the machine body 1 and the drum 2, then control the mounting base 3 to descend and start the motor 5 to rotate in the opposite direction. At this time, pull the drum 2 away from the mounting base 3 so that the drum 2 can be disassembled by detaching it from the fastener 6.

[0030] During the replacement of drum 2, the spirally tapering cavity 8 is designed to forcefully guide the fastener 6 to move along a specific path, ensuring that the clamping force always points towards the central axis of drum 2. The compression spring 7 ensures that the clamping force applied by the two fasteners 6 is basically the same. The combination of the two points ensures that drum 2 is firmly, concentrically and evenly clamped on the fastener 6. At the same time, when the fastener 6 is constrained in the cavity 8, the outward pushing force of the compression spring 7 is transformed into a strong radial clamping force through the action of the spiral surface. It has the characteristics of mechanical self-locking, thus effectively preventing shaking, eccentricity and jumping when drum 2 rotates at high speed, ensuring operational stability and safety.

[0031] The presence of the compression spring 7 gives the mechanism a certain degree of elasticity and self-adaptability. For the drum 2 with slight dimensional deviations, the compression spring 7 can automatically adjust the clamping stroke, absorb some of the dimensional tolerances, ensure reliable clamping effect, and improve the equipment's compatibility with the drum 2.

[0032] Reference Figure 1 and Figure 2The fastener 6 includes a drive section 601 and two force-applying sections 602. One end of the drive section 601 is hinged to the bracket 4, and the two force-applying sections 602 are respectively hinged to the two sides of the drive section 601 away from the bracket 4. The other ends of the two force-applying sections 602 extend in a direction away from each other and press against the inner wall of the cavity 8. In this configuration, the drive section 601 is equivalent to the central connecting rod, and the two force-applying sections 602 are equivalent to the end of the clamping force. They form a branch structure with left and right symmetry. The ends of the force-applying sections 602 form an "outward expansion" posture. When the bracket 4 drives the fastener 6 to rotate, the outward expansion ends of the two force-applying sections 602 first contact the inclined inner wall of the spiral cavity 8. At this time, the inner wall of the cavity 8 will generate a normal reaction force and friction force on the ends of the force-applying sections 602 pointing towards the center of the drum 2. Since the force-applying sections 602 are hinged to the drive end, this normal reaction force will generate a torque relative to the hinge point of the force-applying sections 602. This torque will drive the force-applying section 602 to rotate inward around its hinge point with the drive end. Even if the force-applying section 602 overcomes the tension of the compression spring 7 and retracts inward, as the fastener 6 continues to penetrate deeper into the cavity 8, the end of the force-applying section 602 slides along the spiral cavity wall toward a narrower inner side. The tilt angle of the cavity wall forces the force-applying point to continue rotating inward around the hinge point. In this way, the ends of the two force-applying sections 602 are forced to retract inward from their outward expansion shape, applying a stronger radial clamping force toward the center to the drum 2. At the same time, as the compression spring 7 is further compressed, the stored elastic potential energy is converted into an outward pushing force that is continuously applied to the force-applying section 602. The outward expansion tendency of the force-applying section 602 needs to be balanced by a tighter compression of the cavity wall to obtain a larger normal reaction force. This actually strengthens the radial reaction force applied by the cavity wall to the end of the force-applying section 602, thereby significantly enhancing the radial clamping force of the force-applying section 602 on the drum 2.

[0033] The hinged structure of fastener 6 provides excellent force transmission efficiency and adaptability. The drive section 601, through the force application section 602 as a lever arm, rotates around the hinge point, efficiently converting a small displacement into a large radial closing displacement and clamping force. The hinged structure also allows the force application section 602 to automatically adjust its posture in the inner cavity according to the contact point, ensuring that the end of the force application section 602 always slides tightly against the spiral cavity wall. This multi-degree of freedom ensures that the clamping force is accurately directed towards the center of the drum 2, making the clamping more stable. Finally, under the hinged effect, the end of the force application section 602 can also adjust the contact position through slight rotation, further increasing the reliable clamping effect and self-centering capability.

[0034] The outward expansion design of the force-applying section 602 enhances the clamping force and contact reliability. The outward expansion design at the end of the force-applying section 602 ensures that it will inevitably contact and interact with the inclined cavity wall during the process of entering the cavity 8. This forced contact ensures the reliability of the mechanism's operation. The inclined contact formed after contact can form a wedge effect, further enhancing the force transmission effect and generating a larger radial component force.

[0035] The compression spring 7 indirectly presses the end of the force-applying section 602 against the spiral cavity wall by pushing the force-applying section 602 outward. Under the centrifugal force generated by the rotation of the drum 2, the inclined surface constraint of the cavity wall on the end of the force-applying section 602, combined with the expansion tendency and friction force applied by the compression spring 7, forms an extremely strong mechanical self-locking effect, ensuring that the clamping force is extremely reliable in the working state and will not loosen.

[0036] Reference Figure 1 and Figure 2 One end of the force-applying section 602, which presses against the inner wall of the cavity 8, is fixed with a protrusion 9. The protrusion 9 is arc-shaped. When the force-applying section 602 slides along the inner wall of the cavity 8 under the drive of the bracket 4, the arc-shaped surface of the protrusion 9 becomes the main contact surface with the inner wall of the cavity 8. The orientation of the arc-shaped end of the protrusion 9 is consistent with the path direction of the fastener 6 sliding spirally along the inner wall of the cavity 8. This allows the protrusion 9 to naturally conform to and smoothly slide over the curved contour of the spiral cavity 8 during movement. After the path is matched, it can play a guiding and constraining role. At the same time, the smooth and continuous arc-shaped surface contacts the inner wall of the spiral cavity 8. Compared with flat or angular structures, it significantly reduces the relative friction speed at the contact point or contact line. When the force-applying section 602 moves spirally along the inner cavity, the protrusion 9 and the cavity wall are more likely to undergo relative rolling or compound motion with rolling components, which greatly reduces pure sliding friction. This not only reduces frictional resistance but also reduces wear.

[0037] In one specific embodiment, the arc-shaped structure of the protrusion 9 provides a larger effective contact area, which disperses the huge clamping reaction force generated by the compression spring 7 and the lever mechanism to a wider area, significantly reducing the pressure on the contact surface and avoiding local plastic deformation, crushing or excessive wear. In addition, the arc-shaped mating surface provides a self-stabilizing geometric constraint, effectively preventing the force-applying segment 602 from lateral jumping, swaying or jamming during movement.

[0038] Reference Figure 2 A telescopic member 10 is fixed between the two drive sections 601. The compression spring 7 is telescopically sleeved on the outside of the telescopic member 10. With this configuration, the telescopic member 10 acts as a rigid guide rod, strictly limiting the compression spring 7 to only change length along the axial direction of the telescopic member 10. This effectively prevents the compression spring 7 from lateral bending, twisting, or becoming unstable during compression or extension. This not only greatly reduces abnormal stress and fatigue inside the spring to extend its service life, but also ensures that the compression spring 7 can work stably and reliably throughout its entire stroke range, outputting the designed elastic force. At the same time, the telescopic member 10 ensures that the central axis of the compression spring 7 is always consistent with the designed force direction. This ensures that the elastic force generated by the spring always acts precisely along the predetermined direction on the drive sections 601 on both sides, without generating harmful lateral force components.

[0039] Reference Figure 4 The cavity 8 is located in the middle of the drum and has a ring-shaped groove 11. The protrusion 9 is slidably embedded in the groove 11. With this arrangement, when the drum rotates at high speed, the protrusion 9 can slide in the groove 11. The two side walls of the groove 11 will firmly prevent the protrusion 9 from moving or displacing along the axis of the drum 2, so as to provide axial constraint on the protrusion 9 and prevent serious accidents such as loosening, displacement, eccentricity or even detachment caused by axial movement of the drum 2 during the winding process.

[0040] Reference Figure 2 Limiting members 12 are fixed on the upper and lower sides of the drive section 601, respectively. The limiting members 12 are used to limit the maximum swing amplitude of the force application section 602. With this setting, when the force application section 602 swings outward or inward to tighten to the design limit, the side of the force application section 602 will contact the limiting member 12 on the mounting plate side, forming a rigid block to prevent the force application section 602 from swinging outward beyond the set angle, ensuring that it opens within a safe and controllable range, effectively preventing the compression spring 7 from being overstretched and the hinge mechanism from being overloaded, as well as interference and collision of the internal structure of the mechanism.

[0041] In one specific embodiment, the gap between the two limiting members 12 is slightly larger than the corresponding thickness of the force-applying section 602, providing the necessary swing space, but with almost no excess gap, to limit the movement of the force-applying section 602 in the direction perpendicular to the swing direction, which significantly enhances the positional accuracy and stability of the force-applying section 602 in the clamping state during movement, and such precise limiting constraint helps to ensure that the two force-applying sections 602 on both sides remain symmetrical and synchronized in any position, avoiding uneven clamping caused by skewness.

[0042] Reference Figure 1 and Figure 3 A vertical guide rail 13 is fixed on the body 1. A slider 14 is fixed on one end of the mounting base 3 facing the vertical guide rail 13. The slider 14 can slide up and down in cooperation with the vertical guide rail 13, so that the mounting base 3 can slide up and down along the vertical guide rail 13. With this setting, the cooperation between the slider 14 and the vertical guide rail 13 further restricts the mounting base 3 to move only in the vertical direction, effectively preventing the mounting base 3 from deviating during the up and down sliding process. In addition, it can prevent the mounting base 3 from directly contacting and rubbing against the body 1, which not only makes the sliding of the mounting base 3 smoother, but also avoids the contact surface between the mounting base 3 and the body 1 from being damaged by long-term friction.

[0043] Reference Figure 1The machine body 1 is also equipped with an electric telescopic rod 15. The telescopic end of the electric telescopic rod 15 is fixed to the mounting base 3. With this setting, the mounting base 3 can be moved up and down by controlling the electric telescopic rod 15. This is more precise than manual control and can further improve the automation of the roller replacement process and reduce manual intervention.
