The application provides a infantees machine spool includes: the mounting shaft 10 is provided with a mounting groove 11; the movable piece 20, the movable piece 20 is arranged in the mounting groove 11 through the elastic piece 1.

The mounting groove 11 is formed on the surface of the mounting shaft 10 and has a certain receiving space recessed inward.

The elastic member 1 has characteristics of deformation and restoration. The elastic member 1 may be made of a flexible material (such as rubber, plastic, etc.), or the elastic member 1 may be an elastic structural member such as a spring. One end of the elastic element 1 is connected with the movable element 20, and the other end is connected with the mounting shaft 10; so that the elastic element 1 is in a compressed state and the movable element 20 can sink into the mounting groove 11; so that the elastic member 1 is restored and at least a portion of the movable member 20 can be lifted from the mounting groove 11.

As will be readily appreciated, when the movable member 20 is recessed into the mounting slot 11, the radial dimension of the axial structure formed by the mounting axle 10 and the movable member 20 is reduced; when at least a portion of the movable member 20 is lifted from the mounting groove 11, the radial dimension of the shaft structure formed by the mounting shaft 10 and the movable member 20 becomes large.

Wherein, the mounting shaft 10 is matched with the moving part 20 and is used for mounting the yardage roll 30; the cloth roll 30 is provided with a through hole 31 and a limiting hole 32, and the limiting hole 32 is communicated with the through hole 31.

Specifically, the cloth roll 30 includes a sleeve and a cloth (such as nylon cloth) wound around the sleeve to form a roll, and a through hole 31 and a stopper hole 32 are formed in the sleeve. When in use, the elastic element 1 is firstly in a compressed state, and after the radial dimension of the shaft structure formed by the mounting shaft 10 and the moving element 20 is reduced, the shaft structure can be conveniently inserted into the through hole 31; then, the elastic element 1 is restored, at least a part of the movable element 20 rises and enters the limiting hole 32, and the movable element 20 and the limiting hole 32 are limited mutually, so that the cloth roll 30 can be prevented from rotating relative to the mounting shaft 10.

More specifically, the yardage roll 30 is relatively fixed on the mounting shaft 10 and the movable member 20, and the installation shaft 10 and the movable member 20 can be driven to rotate around the bead ring according to the angle and the gap required by the process when the cloth wrapping machine is in operation, so that the shaft structure releases the cloth and winds the cloth onto the bead ring at the same time.

It should be added that at least one end of the through hole 31 extends through the end of the roll 30 to facilitate the insertion of the mounting shaft 10 and the movable member 20. In order to facilitate the insertion of the mounting shaft 10 and the movable member 20, the aperture of the through hole 31 is not smaller than the outer diameter of the shaft structure when the elastic member 1 is in a compressed state; meanwhile, in order to ensure that the movable member 20 and the limiting hole 32 can be limited to each other, the aperture of the through hole 31 is smaller than the outer diameter of the shaft structure when the elastic member 1 is in the release state.

In one embodiment, the elastic member 1 is restored, and at least a portion of the movable member 20 is lifted and enters the limiting hole 32; when the movable member 20 contacts the limiting hole 32, the elastic member 1 is still in a compressed state, and the elastic force of the elastic member 1 acts on the movable member 20, so that the movable member 20 abuts against the limiting hole 32, and the yardage roll 30 can be prevented from translating relative to the mounting shaft 10 by using the friction force between the shaft structure and the hole wall.

In another embodiment, referring to fig. 2 and 3, the through hole 31 extends along the axial direction of the cloth roll 30, and both ends of the through hole 31 penetrate through the cloth roll 30; when the yardage roll 30 is connected with the shaft structure, the mounting shaft 10 and the movable element 20 can extend into one end of the through hole 31 and penetrate out from the other end of the through hole 31.

With continued reference to fig. 2 and 3, the moveable member 20 has two axially spaced projections; two limiting holes 32 are formed in the cloth roll 30 corresponding to the two bumps; when the cloth roll 30 is mounted in place, the bumps correspond to the limiting holes 32 one by one; the elastic piece 2 is recovered, and the lug can extend into the corresponding limiting hole 32; because the lower end of the limiting hole 32 is open and the front, rear, left, and right sides are closed, the limiting hole 32 can prevent the lug from moving along the axial direction and the circumferential direction.

In this embodiment, even if the elastic member 1 is in the release state, the limiting hole 32 can prevent the yardage roll 30 from translating relative to the mounting shaft 10 as long as the protrusion is ensured to be in the limiting hole 32.

In summary, the winding shaft of the cloth wrapping machine provided by the application is provided with the movable piece 20 capable of elastically moving, so that the radial size of the shaft structure can be changed by deforming the elastic piece 1, and the cloth roll 30 can be conveniently installed or removed, thereby playing the roles of simplifying the roll changing operation and improving the roll changing efficiency.

Further, at least part of the moving part 20 enters the limiting hole 32, and by utilizing the mutual limiting action of the moving part 20 and the limiting hole 32, after the yardage roll 30 is installed in place, the yardage roll can neither move axially along the installation shaft 10 nor rotate relative to the installation shaft 10, so that the installation shaft 10 can be accurately braked by the cloth wrapping machine, and the winding of cloth is realized.

Optionally, a stop 12 is disposed on the mounting shaft 10 or the movable member 20, and the stop 12 is used for limiting the mounting position of the cloth roll 30.

In particular, so that the elastic element 1 is in a compressed state, the shaft structure enters the through hole 31; as the shaft structure continues to penetrate through hole 31, roll 30 approaches stop 12, and roll 30 is mounted in place as roll 30 abuts stop 12.

Stop 12 can quickly prompt an assembler that roll 30 is in place and can prevent roll 30 from continuing to move so that roll 30 stays in the correct mounting position.

Further, the stop 12 can also be used to prevent the roll 30 from translating relative to the mounting shaft 10.

Specifically, the stop 12 includes a first stop 12a and a second stop 12b spaced apart along the axial direction of the mounting shaft 10; after the cloth roll 30 is installed on the installation shaft 10 and the movable member 20, the elastic member 1 is restored, and the cloth roll 30 is located between the first stopper 12a and the second stopper 12b.

After the elastic member 1 is restored, the first stopper 12a and the second stopper 12b cannot enter the through hole 31 and can respectively abut against one end surface of the cloth roll 30, that is, the first stopper 12a and the second stopper 12b can be used for preventing the cloth roll 30 from moving axially along the mounting shaft 10.

In one embodiment, referring to fig. 1, the movable element 20 has a first stopper 12a at a left end and a second stopper 12b at a right end. When the yardage roll 30 is installed, the elastic piece 1 can be compressed by pressing the movable piece 20 or the stop block 12, so that the movable piece 20 and the stop block 12 sink into the installation groove 11; the mounting shaft 10, the movable block 20 and the stopper 12 enter the through hole 31 together; after the yardage roll 30 is installed in place, the first stop block 12a and the second stop block 12b are positioned outside the yardage roll 30; the elastic piece 1 is released, the movable piece 20 and the stop block 12 are lifted, the upper part of the movable piece 20 enters the limit groove 32, and the first stop block 12a and the second stop block 12b are higher than the limit groove 32 and can be matched with and clamp two ends of the cloth roll 30.

In other embodiments, one of the first stop 12a and the second stop 12b is disposed on the mounting shaft 10, and the other is disposed on the movable member 20.

The particular configuration and mounting location of the stop 12 is not a limitation of the present application.

In order to improve the stability of the installation of the movable member 20, in one embodiment, a first end of the movable member 20 is rotatably connected to the installation shaft 10, and a second end of the movable member 20 is connected to the installation shaft 10 through the elastic member 1.

Referring to fig. 4, in the embodiment, the right end of the movable member 20 is rotatably disposed in the mounting groove 11, and the left end is connected to the elastic member 1; the lower end of the elastic element 1 is connected with the groove bottom of the mounting groove 11, and the upper end is connected with the left end of the movable element 20. When the elastic element 1 is compressed, the movable element 20 can rotate anticlockwise and sink into the mounting groove 11; when the elastic member 1 is restored, the movable member 20 can rotate clockwise, and the left end of the movable member 20 can be lifted upward so as to be adjacent to the roll 30.

In one embodiment, the first end of the movable member 20 is rotatably disposed in the mounting slot 11 via the rotary latch 4.

Referring specifically to fig. 4, in the illustrated embodiment, the right end of the movable member 20 is provided with a through hole, and the through hole penetrates through the movable member 20 along a direction perpendicular to the paper; the direction perpendicular to the paper surface in the figure is defined as the width direction, and at this time, two groove surfaces in the width direction of the installation groove 11 are respectively provided with an installation hole; so that the mounting hole is opposite to the through hole, and the rotary lock pin 4 can pass through the through hole and be connected with the mounting hole.

More specifically, one of the through hole and the mounting hole is rotatably connected to the rotary lock pin 4, and the other is fixedly connected to the rotary lock pin 4.

For example, two ends of the rotary lock pin 4 are respectively and rotatably arranged in one mounting hole, and the movable piece 20 is fixedly connected with the rotary lock pin 4; thus, when the elastic element 1 deforms, the movable element 20 can drive the rotating lock pin 4 to rotate relative to the mounting hole.

At this time, the rotary latch 4 may serve as a rotation shaft so that the movable member 20 stably rotates. Meanwhile, the function of the rotary lock pin 4 is added, the pin shaft and the pin hole are arranged, the rotation amplitude of the moving part 20 can be limited, the moving part 20 is prevented from excessively rotating, and therefore the structural reliability of the rotating shaft of the whole cloth wrapping machine is improved.

In one embodiment, a first stop 12a is disposed on the second end of the movable member 20; after the cloth roll 30 is installed in the installation shaft 10 and the movable element 20, the elastic element 1 is restored, and the first stop 12a rotates towards the cloth roll 30 and abuts against the end surface of the cloth roll 30.

Referring specifically to fig. 4, in the illustrated embodiment, a first stop 12a is disposed at the left end of the movable member 20, and the first stop 12a is protruded from the upper surface of the movable member 20; both the through hole 31 and the limiting hole 32 axially penetrate through the cloth roll 30. When the yardage roll 30 is installed, the shaft structure needs to be inserted from the right end of the through hole 31; the elastic part 1 is in a compressed state, the first stop 12a is not higher than the through hole 31 and the limiting hole 32, and the shaft structure can easily enter the through hole 31; after the first stop block 12a enters the through hole 31, the hole wall acts on the first stop block 12a, and the compression state of the elastic part 1 can be kept without manual force application; after the first stop block 12a penetrates out of the left end of the through hole 31, the pressure of the hole wall is lost, the elastic element 1 recovers, so that the movable element 20 rotates clockwise along with the first stop block 12a, the first stop block 12a continuously rises, is finally higher than the through hole 31 and the limiting hole 32, and can abut against the left end surface of the cloth roll 30; and the left end of the movable member 20 connected to the first stopper 12a can enter the stopper hole 32; at this time, the movable member 20 interacts with the limiting hole 32 to prevent the roll 20 from rotating on the shaft structure, and the first stopper 12a prevents the roll 20 from moving leftward.

Further, in order to better prevent the cloth roll 30 from moving axially along the mounting shaft 10, a second stop 12b is provided on the side of the mounting shaft 10 or the movable member 20 away from the first stop 12 a.

For example, in the embodiment shown in fig. 4, two second stops 12b are provided on the right side of the mounting shaft 10. When the yardage roll 30 is installed, the yardage roll 30 is sleeved into the shaft structure from left to right; when the right end face of the cloth roll 30 abuts against the second stop block 12b, the cloth roll 30 comes into position, and the first stop block 12a penetrates out of the left end of the through hole 31; the first stop 12a is able to press the cloth roll 30 against the second stop 12b. In this way, the first stopper 12a and the second stopper 12b are engaged with each other, and the cloth roll 30 can be further fixed.

Alternatively, in the embodiment shown in fig. 5, both ends of the rotary lock pin 4 in the length direction protrude from the through hole 31; with the cloth roll 30 continuously sleeved into the shaft structure, the end part of the rotary lock pin 4 is finally abutted; at this time, the protruding end portion of the rotary lock pin 4 serves as the second stopper 12b.

Alternatively, the farther away from the first end of the movable member 20, the smaller the thickness of the first stop 12 a.

Referring to fig. 4 specifically, in the illustrated embodiment, the first stopper 12a is disposed at the left end of the movable member 20, the first stopper 12a is substantially triangular, the upper surface of the first stopper 12a is an inclined surface, and the upper surface of the first stopper 12a inclines upward from left to right, so that the left end of the limiting block 12 has a small thickness and the right end of the limiting block has a large thickness, and the right end of the limiting block having the large thickness protrudes from the upper surface of the movable member 20, and the protruding portion can abut against the left end surface of the cloth roll 30.

The gradual change of the thickness of the limiting block 12 is beneficial to the nesting and the taking out of the yardage roll 30.

Optionally, the width of the limiting hole 32 is equal to the width of the mounting groove 11.

Wherein, the width direction of the limiting hole 32 and the mounting groove 11 is perpendicular to the radial direction and the axial direction of the mounting shaft 10. The width of the limiting hole 32 is equal to the width of the mounting groove 11, so that the movable member 20 can sink into the mounting groove 11 and can enter the limiting hole 32.

To improve the applicability of the spreader reel provided by the present application, the length of the mounting shaft 10 is optionally adjustable.

The length of the mounting shaft 10 is adjusted to be beneficial to adapting to yardage rolls 30 with different specifications. Especially when the stop 12 is disposed on the mounting shaft 10, the length of the mounting shaft 10 can be adjusted to ensure that the yardage rolls 30 of different specifications can be accurately abutted against the stop 12.

In one embodiment, the mounting shaft 10 includes at least two mounting sections, which can be assembled together by means of insertion, screwing, magnetic attraction, etc.; the number of assembled mounting sections is reduced, i.e. the length of the mounting shaft 10 can be reduced; increasing the number of mounting sections that are assembled increases the length of the mounting shaft 10.

In another embodiment, the mounting shaft 10 is in a telescoping rod configuration; the installation axle 10 includes a fixed axle and at least one loose axle, and the loose axle slides and sets up in the fixed axle, through tensile loose axle, can increase the length of installation axle 10, through the tamponade loose axle, can reduce the length of installation axle 10.

In yet another embodiment, the moveable member 20 includes: the first section 21 is provided with a first screw hole; the second section 22, the second section 22 is equipped with the second screw; the winding shaft of the cloth wrapping machine also comprises a stud bolt 2, and threads at two ends of the stud bolt 2 are positive and negative threads; the first screw hole and the second screw hole are respectively in threaded connection with one end of the stud bolt 2.

In this embodiment, the insertion depth of the threaded rod into the threaded hole can be adjusted by rotating the stud 2, thereby adjusting the distance between the first section 21 and the second section 22, and thus the length of the movable member 20.

Optionally, the stud 2 is provided with four outer corners 3, and the connection depth between the stud 2 and the movable member 20 can be adjusted by screwing the four outer corners 3.

Wherein, the outer four corners 3 can be integrally formed with the stud bolts 2 and positioned between the threaded rods at the two ends. Or, the inner circle of outer four corners 3 is provided with the internal thread, and through the threaded rod of one end wherein, rotatory outer four corners 3 can twist outer four corners 3 in stud 2's middle part, and the threaded rod of the reuse other end revolves to the opposite settlement of settlement and prescribes a limit to outer four corners 3, avoids outer four corners 3 to remove through rotatory on the threaded rod of the other end, so, twists outer four corners 3 towards the threaded rod of the other end, can rotate stud 2 to realize the adjustment of moving part 20 length.
