Description

Technical Field

[0001] This invention relates to the field of warping machine technology, and in particular to a clutch-type telescopic reed for batch warping machines. Background Technology

[0002] A telescopic reed is a component used in warping machines. It mainly consists of a reed base and multiple reed blades arranged in a continuous zigzag pattern, allowing for free adjustment of the working width. Telescopic reeds play a crucial role in textile machinery, accommodating fabrics of varying widths and lengths, thereby improving production efficiency and product quality.

[0003] Existing telescopic reeds need to have the following functions: 1) reciprocating motion to ensure stable yarn winding and prevent sagging; 2) angle adjustment (density adjustment) so that when the warping machine winds different numbers of yarns, only the density of the telescopic reed needs to be adjusted, without replacing the reed. There are many ways to achieve these functions, but currently there are two main types: one uses a motor at each end of the telescopic reed, driving screws at both ends. The two motors rotate in the same direction to adjust the density, and rotate in opposite directions to drive the reciprocating motion; the other uses a single motor to drive the screws to adjust the density, with a separate mechanism for the reciprocating motion, as in the invention patent with authorization announcement number CN202440613U. The first method requires two motors to work together for adjustment, necessitating consideration of motor synchronization, thus requiring a servo motor, which increases cost and complicates program control. The second method requires a separate mechanism, resulting in a more complex structure and introducing more assembly and cost issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of the existing telescopic reeds, which have complex structures or complex control programs and thus poor operational stability, the present invention provides a clutch-type telescopic reed for batch warping machines. By improving its transmission structure, it only requires one motor to drive it, which can simultaneously realize left and right reciprocating motion and density adjustment. The structure is simple and the requirements for program control are also low.

[0005] The technical solution adopted by this invention to solve its technical problem is: a clutch-type telescopic reed for a batch warping machine, comprising a reed base, reed plates, and a transmission mechanism. Multiple reed plates are present, and adjacent reed plates are connected by a hinge structure and mounted on the reed base. The transmission mechanism is mounted on the reed base and includes a motor, a left drive screw, a left drive nut, a right drive screw, a right drive nut, and a clutch. The left and right drive screws have the same pitch and direction of rotation, and are located on the left and right sides of the clutch, respectively, and are connected via the clutch. The motor is located at the end of the transmission mechanism and drives the left or right drive screw. The connection is as follows: the left drive nut is threaded onto the left drive screw, and the upper end of the left drive nut is fixedly connected to a reed; the right drive nut is threaded onto the right drive screw, and the upper end of the right drive nut is fixedly connected to another reed; when the clutch is disengaged, the motor rotates, which can only drive the drive screw directly connected to it to rotate, thereby increasing or decreasing the distance between the left and right drive nuts, and adjusting the distance between the reeds; when the clutch is engaged, the motor rotates, which drives the left and right drive screws to rotate synchronously, the distance between the left and right drive nuts remains unchanged, and the two move synchronously in the same direction, thereby realizing the overall movement of the reeds.

[0006] To enable the rotation and support of the left drive screw, the transmission mechanism further includes a left bearing assembly and a right bearing assembly. The left bearing assembly includes a left bearing housing, a left deep groove ball bearing, and a left bearing retaining ring. The left bearing housing is fixed to the reed seat by bolts or other fasteners. The left deep groove ball bearing is installed inside the left bearing housing and fixed within the left bearing housing by the left bearing retaining ring. The left end of the left drive screw is connected to the left deep groove ball bearing. The right bearing assembly includes a right bearing housing and a right deep groove ball bearing. The right bearing housing is fixed to the reed seat by bolts or other fasteners. The right deep groove ball bearing is installed inside the right bearing housing, and the right end of the left drive screw is connected to the right deep groove ball bearing.

[0007] The drive screw is relatively long, and its expansion and contraction due to temperature changes are significant. Therefore, the left deep groove ball bearing is fixed to the left bearing housing by a left retaining ring, while the right deep groove ball bearing is not fitted with a retaining ring and remains floating, allowing it to slide axially within the right bearing housing. This structure, where one bearing remains floating, allows the axial sliding of the bearing to offset the expansion and contraction of the drive screw, preventing the bearing from being squeezed and damaged.

[0008] To enable the rotation and support of the right-side drive screw, the transmission mechanism further includes a left second bearing assembly and a right second bearing assembly. The left second bearing assembly includes a left second bearing housing, a left second deep groove ball bearing, and a left second bearing retaining ring. The left second bearing housing is fixed to the reed seat by bolts or other fasteners. The left second deep groove ball bearing is installed inside the left second bearing housing and fixed inside the left second bearing housing by the left second bearing retaining ring. The left end of the right drive screw is connected inside the left second deep groove ball bearing. The right second bearing assembly includes a right second bearing housing and a right second deep groove ball bearing. The right second bearing housing is fixed to the reed seat by bolts or other fasteners. The right second deep groove ball bearing is installed inside the right second bearing housing, and the right end of the right drive screw is connected inside the right second deep groove ball bearing.

[0009] The second deep groove ball bearing on the left is fixed to the second bearing housing on the left by the second retaining ring, while the second deep groove ball bearing on the right is not equipped with a retaining ring and remains floating, and can slide axially within the second bearing housing on the right. Its structure has the same function as the first bearing assembly on the left and the first bearing assembly on the right, so it will not be described in detail here.

[0010] To connect the clutch to the two drive screws, the transmission mechanism further includes a left connecting shaft, a left coupling, a right connecting shaft, a right coupling, a left three-bearing assembly, and a right three-bearing assembly. The right end of the left connecting shaft is connected to the left end of the clutch via a key. The left end of the left connecting shaft is rotatably supported on a reed seat via the left three-bearing assembly, and its end passes through the left three-bearing assembly and connects to the right end of the left drive screw via the left coupling. Similarly, the left end of the right connecting shaft is connected to the right end of the clutch via a key. The right end of the right connecting shaft is rotatably supported on a reed seat via the right three-bearing assembly, and its end passes through the right three-bearing assembly and connects to the left end of the right drive screw via the right coupling.

[0011] Furthermore, the left three-bearing assembly and the right three-bearing assembly have the same structure. The left three-bearing assembly includes a left three-bearing housing, a left three-deep groove ball bearing, and a left three-bearing retaining ring. The left three-bearing housing is fixed to the reed seat by bolts or other fasteners. The left three-deep groove ball bearing is installed inside the left three-bearing housing and is fixed inside the left three-bearing housing by the left three-bearing retaining ring. The left end of the left connecting shaft is connected to the left three-deep groove ball bearing. The right three-bearing assembly includes a right three-bearing housing, a right three-deep groove ball bearing, and a right three-bearing retaining ring. The right three-bearing housing is fixed to the reed seat by bolts or other fasteners. The right three-deep groove ball bearing is installed inside the right three-bearing housing and is fixed inside the right three-bearing housing by the right three-bearing retaining ring. The right end of the right connecting shaft is connected to the right three-deep groove ball bearing.

[0012] To support the motor, a motor mounting base is also included. The motor mounting base is fixedly connected to the reed base, and the motor housing is fixedly connected to the motor mounting base by screws, bolts, or other fasteners.

[0013] In order to realize the transmission connection between the motor and the transmission screw, the transmission mechanism also includes a motor coupling, one end of which is connected to the output shaft of the motor, and the other end is connected to the end of one of the left and right transmission screws.

[0014] In a further preferred embodiment, the left drive screw and the left drive nut are connected by an automatic locking structure, and the right drive screw and the right drive nut are connected by an automatic locking structure.

[0015] The beneficial effects of the present invention are as follows: The clutch-type telescopic reed for batch warping machine provided by the present invention uses only one motor to drive it. By opening and closing the clutch, it can realize two functions: left and right reciprocating motion of the telescopic reed and angle adjustment (density adjustment). The structure is relatively simple, and the program control is also simpler. Therefore, the operation stability is better and the warping quality is better. Attached Figure Description

Detailed Implementation

[0023] The invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner. Therefore, they only show the components relevant to the invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0024] like Figure 1 As shown, a clutch-type telescopic reed for a batch warping machine according to the present invention includes a reed base 17, reed pieces 19, and a transmission mechanism. There are multiple reed pieces 19, and the reed pieces 19 are interlocked with each other. Adjacent reed pieces 19 are connected by a hinge structure and are disposed on the reed base 17. The hinge structure connecting the reed pieces 19 is an existing structure, mainly composed of multiple hinges 18 and multiple support blocks 20. The hinges 18 are sequentially hinged to each other by the support blocks 20. Two hinges 18 can rotate relative to each other about the support blocks 20 as the axis of rotation. In this way, all reed pieces 19 and hinges 18 are connected as a whole and can be stretched and contracted left and right as a whole. Two reed pieces 19 are respectively connected to two transmission nuts. Therefore, the transmission nuts can drive the reed pieces 19 and hinges 18 to move as a whole.

[0025] like Figures 2-5 As shown, the transmission mechanism is mounted on the reed seat 17 and includes a motor 1, a motor mounting base 2, a left transmission screw 4a, a left transmission nut 8a, a right transmission screw 4b, a right transmission nut 8b, and a clutch 15. The motor mounting base 2 is fixedly connected to the reed seat 17, and the housing of the motor 1 is fixedly connected to the motor mounting base 2 by screws and other fasteners. In this embodiment, the structure of the entire transmission mechanism is illustrated by taking the motor 1 located on the left side of the reed seat 17 as an example. Both the left and right transmission screws 4a and 4b are trapezoidal threaded screws with the same pitch and direction of rotation. They are respectively located on the left and right sides of the clutch 15. The left transmission nut 8a is threadedly engaged with the left transmission screw 4a, and its upper end is fixedly connected to a reed plate 19. The right transmission nut 8b is threadedly engaged with the right transmission screw 4b, and its upper end is fixedly connected to another reed plate 19. The transmission screws drive the transmission nuts to move left and right. Preferably, the left drive screw 4a and the left drive nut 8a are connected by an automatic locking structure, and the right drive screw 4b and the right drive nut 8b are connected by an automatic locking structure.

[0026] The left drive screw 4a is supported on the reed seat 17 at both ends by the first left bearing assembly and the first right bearing assembly, respectively, which can realize the smooth transmission of the left drive screw 4a; the right drive screw 4b is supported on the reed seat 17 at both ends by the second left bearing assembly and the second right bearing assembly, respectively, which can realize the smooth transmission of the right drive screw 4b. The structure of the four bearing assemblies is given below.

[0027] Specifically, the left bearing assembly includes a left bearing housing 5, a left deep groove ball bearing 6, and a left bearing retaining ring 7. The left bearing housing 5 is fixed to the reed seat 17 by bolts or other fasteners. The left deep groove ball bearing 6 is installed inside the left bearing housing 5, and the left deep groove ball bearing 6 is fixed inside the left bearing housing 5 by the left bearing retaining ring 7. The left end of the left drive screw 4a is connected inside the left deep groove ball bearing 6. The right bearing assembly includes a right bearing housing 9 and a right deep groove ball bearing 10. The right bearing housing 9 is fixed to the reed seat 17 by bolts or other fasteners. The right deep groove ball bearing 10 is installed inside the right bearing housing 9, and the right end of the left drive screw 4a is connected inside the right deep groove ball bearing 10.

[0028] The structures of the left second bearing assembly and the right second bearing assembly are basically the same as those of the left first bearing assembly and the right first bearing assembly. Specifically, the left second bearing assembly includes a left second bearing housing 26, a left second deep groove ball bearing 27, and a left second bearing retaining ring 28. The left second bearing housing 26 is fixed to the reed seat 17 by bolts or other fasteners. The left second deep groove ball bearing 27 is installed inside the left second bearing housing 26, and the left second deep groove ball bearing 27 is fixed inside the left second bearing housing 26 by the left second bearing retaining ring 28. The left end of the right drive screw 4b is connected inside the left second deep groove ball bearing 27. The right second bearing assembly includes a right second bearing housing 29 and a right second deep groove ball bearing 30. The right second bearing housing 29 is fixed to the reed seat 17 by bolts or other fasteners. The right second deep groove ball bearing 30 is installed inside the right second bearing housing 29, and the right end of the right drive screw 4b is connected inside the right second deep groove ball bearing 30.

[0029] Of the two pairs of bearing assemblies mentioned above, one side is equipped with a bearing retainer ring and the other side is not equipped with a bearing retainer ring. This allows the bearing on the right side to remain in a floating state and slide axially within the bearing housing, absorbing the axial expansion and contraction of the transmission screw caused by temperature differences.

[0030] like Figure 4 As shown, in this embodiment, the motor 1 is located at the left end of the transmission mechanism and is therefore connected to the left transmission screw 4a. In order to achieve a smooth transmission connection between the motor 1 and the left transmission screw 4a, a motor coupling 3 is also included. One end of the motor coupling 3 is connected to the output shaft of the motor 1, and the other end is connected to the end of the left transmission screw 4a.

[0031] like Figure 5As shown, in order to achieve the connection and smooth transmission between the clutch 15 and the two drive screws, the transmission mechanism further includes a left connecting shaft 14, a left coupling 21, a right connecting shaft 16, a right coupling 22, a left three-bearing assembly, and a right three-bearing assembly. The right end of the left connecting shaft 14 is connected to the left end of the clutch 15 via a key, and the left end of the left connecting shaft 14 is rotatably supported on the reed seat 17 via the left three-bearing assembly. The end of the shaft passes through the left three-bearing assembly and is connected to the right end of the left drive screw 4a via the left coupling 21. The left end of the right connecting shaft 16 is connected to the right end of the clutch 15 via a key, and the right end of the right connecting shaft 16 is rotatably supported on the reed seat 17 via the right three-bearing assembly. The end of the right connecting shaft 16 passes through the right three-bearing assembly and is connected to the left end of the right drive screw 4b via the right coupling 22. The left three-bearing assembly and the right three-bearing assembly have basically the same structure. The left three-bearing assembly includes a left three-bearing housing 13, a left three-deep groove ball bearing 12, and a left three-bearing retaining ring 11. The left three-bearing housing 13 is fixed to the reed seat 17 by bolts or other fasteners. The left three-deep groove ball bearing 12 is installed inside the left three-bearing housing 13, and the left three-deep groove ball bearing 12 is fixed within the left three-bearing housing 13 by the left three-bearing retaining ring 11. The left end of the left connecting shaft 14 is connected to the left... The right three-groove ball bearing assembly includes a right three-groove bearing housing 23, a right three-groove ball bearing 24, and a right three-groove bearing retaining ring 25. The right three-groove bearing housing 23 is fixed to the reed seat 17 by bolts or other fasteners. The right three-groove ball bearing 24 is installed inside the right three-groove bearing housing 23 and is fixed inside the right three-groove bearing housing 23 by the right three-groove bearing retaining ring 25. The right end of the right connecting shaft 16 is connected inside the right three-groove ball bearing 24.

[0032] Working principle:

[0033] When the clutch 15 is disengaged, the motor 1 rotates, which can only drive the left drive screw 4a, which is directly connected to it, to rotate. This causes the left drive nut 8a to move, while the right drive screw 4b remains stationary, thus keeping the right drive nut 8b stationary. This increases or decreases the distance between the left drive nut 8a and the right drive nut 8b, thereby pulling the hinge 18 to extend or retract, thus adjusting the distance between the reeds 19, i.e., adjusting the angle of the reeds 19 to achieve density adjustment.

[0034] When the clutch 15 is engaged, the motor 1 rotates, driving the left drive screw 4a and the right drive screw 4b to rotate synchronously. The distance between the left drive nut 8a and the right drive nut 8b remains unchanged, and the two move synchronously in the same direction, realizing the overall movement of the reed 19.

[0035] This invention employs a clutch 15 located in the middle. The opening and closing of the clutch 15 controls the connection and disconnection between the left and right transmission screws. The transmission screws on both sides of the clutch 15 use screws with the same pitch and direction of rotation to ensure that the transmission nuts on both sides move left and right at the same speed. The transmission screws and transmission nuts have a self-locking structure; only the torque driven by the rotation of the transmission screws can cause the transmission nuts to move left and right. The torque generated by forces in other directions is balanced by the torque generated by the frictional force that occurs simultaneously.

[0036] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of the present invention. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
