The cantilever structure shuttle plate reciprocating motion has a large load, large equipment shaking, high drive energy consumption, and loud noise. The linear bearings also require regular lubrication and maintenance, which is costly. If the linear bearings are damaged, replacement is troublesome and costly. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a device for the reciprocating motion of a shuttle plate of a fabric spreading machine. The device is guided and supported by two wheel sets in the middle and two side roller sets. The overall motion device is a non-cantilever structure, the overall structure of the shuttle plate is lighter, the driving energy consumption is lower, the operation is quiet and stable, and the maintenance cost is lower.

[0004] The technical solution of the present invention is: a device for the reciprocating motion of a shuttle plate of a fabric spreading machine, comprising a shuttle plate, two fixed plates, a rotating shaft, a drive motor, two sets of shuttle plate guiding mechanisms and two sets of shuttle plate transmission mechanisms;

[0005] The two fixing plates are placed horizontally, one on the left and one on the right, and the top of the fixing plates is fixed to the main frame of the spreading machine.

[0006] The rotating shaft is arranged horizontally in the left-right direction, and both ends of the rotating shaft are rotatably fixed to the front of the two fixing plates.

[0007] The drive motor is fixed on the main frame of the fabric spreading machine, and the output shaft of the drive motor is connected to the rotating shaft through a motor conveyor belt. The rotation of the drive motor drives the rotating shaft to rotate synchronously.

[0008] The two sets of shuttle board guiding mechanisms are symmetrically fixed to the bottom of the two fixed plates. Each set of shuttle board guiding mechanisms includes a central guide shaft and a set of central wheels. The central wheels include a central wheels connecting plate and multiple pairs of upper and lower guide wheels symmetrically arranged vertically on the central wheels connecting plate. The central guide shaft is horizontally arranged at the bottom of the fixed plate in the front-back direction, and the central part of the central guide shaft passes between the upper and lower guide wheels. The front and rear ends of the central guide shaft are fixed to the bottom of the fixed plate. The two central wheels connecting plates are fixedly connected to the shuttle board through central wheels connecting brackets, so that the shuttle board can move back and forth along the direction of the central guide shaft.

[0009] The two sets of shuttle plate transmission mechanisms are symmetrically fixed to the bottom of the two fixed plates. Each set of shuttle plate transmission mechanisms includes a shuttle plate conveyor belt arranged horizontally in the front-to-back direction. One end of the shuttle plate conveyor belt is sleeved on the rotating shaft, so that the shuttle plate conveyor belt can rotate synchronously with the rotating shaft. The two shuttle plate conveyor belts are fixedly connected to the shuttle plate through conveyor belt connecting brackets, so that the shuttle plate conveyor belts can drive the shuttle plate to move synchronously when they move.

[0010] Furthermore, it also includes two sets of shuttle plate side guide mechanisms; the two sets of shuttle plate side guide mechanisms are respectively disposed at both ends of the shuttle plate;

[0011] Each shuttle board side guide mechanism includes a side guide rail, a side wheel set, and a side wheel set connecting plate; the side wheel set includes multiple horizontal guide wheels and multiple vertical guide wheels. The horizontal guide wheels are fixed to the side wheel set connecting plate and can roll in contact with the inner surface of the side plate of the side guide rail. The vertical guide wheels are fixed to the side wheel set connecting plate and can roll in contact with the inner surface of the bottom plate of the side guide rail.

[0012] The two side wheel assembly connecting plates are fixedly connected to both ends of the shuttle plate, so that the shuttle plate moves in a rolling motion when it moves back and forth.

[0013] Furthermore, each set of intermediate wheels has three pairs of upper guide wheels and lower guide wheels.

[0014] Furthermore, each set of side wheels has 2 lateral guide wheels and 4 vertical guide wheels.

[0015] The beneficial effects of this invention are: it provides a device for the reciprocating motion of a shuttle board in a fabric spreading machine, which uses two central wheel sets and two side roller sets for guidance and load-bearing. The overall motion device is not a cantilever structure, making the overall shuttle board structure lighter, reducing drive energy consumption, ensuring quiet and stable operation, and lowering maintenance costs. It solves the various drawbacks of cantilever structures in shuttle board reciprocating motion, which require greater driving force, increase noise over long operating times, and have high manufacturing and maintenance costs.

[0016] This device avoids the cantilevered motion posture of the shuttle plate reciprocating motion device of the fabric spreading machine. It uses two wheel sets in the middle and a guide shaft to guide and bear the weight of the shuttle plate reciprocating motion. At the same time, the side roller sets on both sides cooperate with the side rails to share the weight and guide the reserve on both sides of the shuttle plate. Attached Figure Description

Detailed Implementation

[0030] The present invention will now be further described with reference to the accompanying drawings.

[0031] The function of the fabric spreading machine is to allow the manual hanging of two corners of the washed linens, sheets, or duvet covers on the fabric feeding clamp, and then the fabric spreading machine flattens the linens and sends the flat linens to the ironing machine for ironing.

[0032] To describe the reciprocating motion principle of the shuttle board Figure 1 , 2 The main structural modules of the fabric spreading machine are shown, including the main frame 1, fabric feeding mechanism 2, fabric spreading mechanism 3, shuttle plate reciprocating motion device 4, and linen conveyor belt mechanism 5.

[0033] Operation steps: The worker manually hangs the linen 6 on the clamps of the feeding mechanism 2. The feeding mechanism 2 then feeds the linen to the two spreading clamps of the spreading mechanism 3. These spreading clamps extend to both sides, straightening the linen 6. Figure 3 , 4 5. The linen 6, through other auxiliary mechanisms, will have its top edge stretched straight and pressed tightly against the shuttle plate 7 and clamped as if... Figure 6 , 7 As shown. After the shuttle plate 7 receives the linen 6, it is driven by the drive motor 8 to move backward. Then, the linen clamping clamp of the shuttle plate 7 opens, laying the linen 6 onto the linen conveyor belt mechanism 5. Figure 8 As shown, the linen conveyor belt mechanism 5 transports the linen 6 out. The shuttle plate 7 is then driven by the drive motor 8 to return to the linen receiving position in the opposite direction, and this cycle repeats.

[0034] In completing the above action cycle, a relatively important structure is the shuttle plate reciprocating motion device 4, which is the core content of this application. The basic components of this device are: shuttle plate 7, drive motor 8, intermediate guide shaft 9, intermediate wheel set 10, side guide rail 11, and side wheel set 12.

[0035] The guidance and load-bearing of the shuttle's reciprocating motion 7 are accomplished through the cooperation of the central guide shaft 9 and the central wheel assembly 10 in the middle section, and the side guide rail 11 and the side wheel assembly 12 in the side section. The cooperation of the central guide shaft 9 and the central wheel assembly 10 in the middle section provides two symmetrical sets of guidance and load-bearing for the shuttle's reciprocating motion 7. Similarly, the cooperation of the side guide rail 11 and the side wheel assembly 12 in the side section provides two symmetrical sets of guidance and load-bearing for the side sections. The guidance provided by the side guide rail 11 and the side wheel assembly 12 serves as a guide reserve; they only function when the central wheel assembly 10 malfunctions and loses its guiding function. The shuttle's reciprocating motion 4 can still operate normally without affecting production. This combination of two sets of guidance and load-bearing devices ensures the stability of the shuttle 7 throughout its reciprocating motion, preventing any shaking and extending its service life.

[0036] The mating structure between the intermediate guide shaft 9 and the intermediate wheel assembly 10 in the middle section, such as... Figure 11a , Figure 11b , Figure 11c As shown in Figure 11(d), the mating structure between the side guide rail 11 and the side wheel assembly 12 is as follows. Figure 12a , Figure 12b , Figure 12c , Figure 12d , Figure 12e and Figure 12f As shown. The specific results are as follows:

[0037] The device for the reciprocating motion of the shuttle plate of the fabric spreading machine includes a shuttle plate 7, two fixed plates 16, a rotating shaft 14, a drive motor 8, two sets of shuttle plate guiding mechanisms, two sets of shuttle plate transmission mechanisms, and two sets of shuttle plate side guiding mechanisms.

[0038] The two fixing plates 16 are placed horizontally, one on the left and one on the right, with their tops fixed to the main frame 1 of the fabric spreading machine. The rotating shaft 14 is arranged horizontally in the left-right direction, and its two ends are rotatably fixed to the front sides of the two fixing plates 16. The drive motor 8 is fixed to the main frame 1 of the fabric spreading machine, and the output shaft of the drive motor 8 is connected to the rotating shaft 14 through a motor conveyor belt 13. The rotation of the drive motor 8 drives the rotating shaft 14 to rotate synchronously.

[0039] The two sets of shuttle guide mechanisms are symmetrically fixed to the bottom of the two fixed plates 16. Each set of shuttle guide mechanisms includes a central guide shaft 9 and a set of central wheel groups 10. The central wheel group 10 includes a central wheel group connecting plate 19 and three pairs of upper guide wheels 20 and lower guide wheels 21 symmetrically arranged vertically on the central wheel group connecting plate 19. The central guide shaft 9 is horizontally arranged at the bottom of the fixed plate 16 in the front-back direction, and the central guide shaft 9 passes between the upper guide wheels 20 and the lower guide wheels 21. The front and rear ends of the central guide shaft 9 are fixed to the bottom of the fixed plate 16. The two central wheel group connecting plates 19 are fixedly connected to the shuttle 7 through central wheel group connecting brackets 18, so that the shuttle 7 can move back and forth along the direction of the central guide shaft 9.

[0040] The two sets of shuttle plate transmission mechanisms are symmetrically fixed to the bottom of the two fixed plates 16. Each set of shuttle plate transmission mechanisms includes a shuttle plate conveyor belt 15 arranged horizontally in the front-to-back direction. One end of the shuttle plate conveyor belt 15 is sleeved on the rotating shaft 14, so that the shuttle plate conveyor belt 15 can rotate synchronously with the rotating shaft 14. Both shuttle plate conveyor belts 15 are fixedly connected to the shuttle plate 7 through conveyor belt connecting brackets 17, so that the shuttle plate conveyor belts 15 can drive the shuttle plate 7 to move synchronously when they move.

[0041] The two sets of shuttle board side guide mechanisms are respectively disposed at both ends of the shuttle board 7. Each set of shuttle board side guide mechanisms includes a side guide rail 11, a side wheel set 12, and a side wheel set connecting plate 22. The side wheel set 12 includes two transverse guide wheels 24 and four vertical guide wheels 23. The transverse guide wheels 24 are fixed to the side wheel set connecting plate 22 and can roll in contact with the inner surface of the side plate of the side guide rail 11. The vertical guide wheels 23 are fixed to the side wheel set connecting plate 22 and can roll in contact with the inner surface of the bottom plate of the side guide rail 11. The two side wheel set connecting plates 22 are respectively fixedly connected to both ends of the shuttle board 7, so that the shuttle board 7 moves in a rolling motion when moving back and forth.

[0042] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
