[0002] The existing cloth spreading machine mainly moves linearly on the cloth spreading platform, spreads the cloth on the cloth roll on the platform, and cuts it into neatly stacked layers of cloth. However, the cloth spreading machine has a fixed working state because the fixed component of the output end is only set in one direction when discharging the material. Therefore, it can only perform one-way cloth spreading, that is, the workstation is unique. It starts from the origin and moves back to the cloth discharging end, and does not perform cloth spreading work during the return movement. Therefore, it can only perform single-station cloth spreading. The cloth spreading speed is therefore slow and the production efficiency is relatively low. In addition, the cloth spreading machine requires personnel to move with it on the standing platform of the cloth spreading machine, or at one end of the platform, observe whether there is any misalignment of the cloth so as to level the cloth, which is more troublesome to handle. Moreover, the general cloth spreading machine is equipped with a distance measuring device. When it detects that there is someone at one end, it will stop moving and spreading the cloth. Therefore, when the staff is leveling, the cloth spreading efficiency of the cloth spreading machine is affected.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 10 As shown, the present invention provides a double-station cloth processing spreading machine, comprising a spreading platform 100 and a spreading machine body 200 slidably mounted thereon, the spreading machine also comprising flattening components 300 arranged on both sides of the spreading platform 100, the flattening components 300 are used to press and flatten the ends of the cloth at both ends of the cloth respectively; wherein, the spreading machine body 200 comprises a guide plate 201 arranged on one side thereof for pulling the cloth, a cloth placing mechanism 400 is arranged at the bottom of the guide plate 201; the cloth placing mechanism 400 comprises a channel steel 401 fixedly connected to the bottom end of the guide plate 201, two active rollers 402 are installed inside the channel steel 401 for biting and conveying the cloth, a driving gear 403 is installed on the top of the channel steel 401, cutting mechanisms 404 are slidably mounted on both sides of the channel steel 401, and the driving gear 403 is transmission-connected with the guide plate 202.

[0021] The present application provides flattening components 300 at both ends of the spreading platform 100, so that the flattening components 300 can respectively press the two ends of the cloth after the spreading machine body 200 puts down the cloth, and can flatten it at the same time. In this way, the spreading machine can spread the cloth in both directions on the spreading platform 100. The cutting mechanism 404 is installed on both sides of the channel steel 401, and can cut the cloth pulled out in two directions respectively, so as to assist the double-station spreading of the spreading machine.

[0022] like Figure 4 and Figure 5As shown, two driving gears 403 are provided and meshed with each other, and two guide plates 202 are provided and are respectively installed on one driving gear 403; The two guide plates 202 are respectively located on both sides of the channel steel 401 and are driven synchronously.

[0023] The active gear 403 can rotate to control the angle between the guide plate 202 and the horizontal plane, thereby adjusting the height of the guide plate 202 from the table surface, so as to continuously adapt to the changing thickness of the cloth layer. The active roller 402 is used to actively pull the cloth down. Since the cloth in this application needs to be released from both ends of the cloth spreading platform 100, the cutting mechanism 404 is set on both sides of the channel steel 401 to cut the cloth when it points to two different directions.

[0024] When the cloth is pulled to one end of the spreading platform 100 and reaches the flattening assembly 300, the cloth is in a straight state as a whole because the flattening assembly 300 at the other end is in a compressed state, so the cloth does not have wrinkles at this time. Alternatively, the two active rollers 402 can also be configured so that one of the active rollers 402 has a spiral rib, which is designed as a flattening roller to further flatten the cloth when released. Ensure that the tail end of the cloth is in a straight state.

[0025] Since the cloth put down again at this end has no fixed position temporarily, it is difficult to ensure that it is a flat state without wrinkles and an aligned state with the lower layer of cloth. Therefore, after the paving machine body 200 is withdrawn and released, the flattening assembly 300 returns to one side of the cloth, compacts it and starts to flatten it.

[0026] The height of the cloth placing mechanism 400 can be adjusted to make it as close to the surface of the cloth spreading platform 100 as possible, so as to ensure that the placed cloth will not be folded.

[0027] like Figure 1-6 As shown, the flattening assembly 300 includes a slide rail 306 disposed on the cloth spreading platform 100, a fixed plate 301 is slidably mounted on the slide rail 306, and a flattener 302 is mounted on the fixed plate 301 for being placed on the end of the cloth to flatten it and fix its position; Ribs with opposite spiral directions are respectively provided at two ends of the outer circumference of the leveler 302 .

[0028] In this embodiment, the flattening assembly 300 has the function of flattening and pressing the cloth, and the flattening method is a rotating roller with spiral ribs, which is a general method of flattening. Different from the prior art, the flattening roller itself can move. When new cloth is put down, the flattener 302 as a whole temporarily withdraws with the flattening assembly 300. After the cloth is put down, the flattener 302 returns to the top of the cloth with the flattening assembly 300, presses the put down cloth and starts flattening. The movement method of the flattening assembly 300 is not limited in this embodiment, and it can be active movement or passive movement.

[0029] Therefore, the flattening assembly 300 can flatten and compact the cloth at both ends, which is different from the conventional single-side compaction. The compaction method of the present application provides the conditions for bidirectional spreading, and realizes the double-station processing and flattening of the cloth.

[0030] like Figure 4-10 As shown, the flattening assembly 300 further includes a cantilever 303, which is fixedly mounted on the outer side of the fixing plate 301; The force-applying wheel group 304 is composed of a driving wheel located at the bottom and a passive wheel located at the top. The driving wheel and the passive wheel are connected by a belt transmission. The driving wheel is installed on the fixed plate 301, and the passive wheel is installed on the top of the cantilever 303; The transmission wheel set 305 is rotatably mounted on the cantilever 303 and is drivingly connected to the passive wheel; The driving wheel is in rolling contact with the table surface of the cloth spreading platform 100; The leveler 302 is movably mounted on the fixed plate 301 through a rotating arm 3022. One end of the leveler 302 is elastically connected to a spring 3029. When the cloth-laying machine body 200 moves to the flattening assembly 300, the guide plate 202 lifts up the leveler 302 that presses the cloth and connects it with the transmission wheel group 305 in a rolling connection. The transmission wheel group 305 drives the leveler 302 to rotate and stores power through the spring 3029.

[0031] In this embodiment, the paving machine body 200 moves to the flattening assembly 300, and first lifts up the leveler 302 to make it roll in contact with the transmission wheel set 305. Since the transmission wheel set 305 is installed through the cantilever 303, there is no transmission space between the cantilever 303 and the fixed plate 301, so the paving machine body 200 continues to move forward, which will push the flattening assembly 300 to slide as a whole. The active wheel of the force wheel set 304 rolls in contact with the table of the paving platform 100. As the flattening assembly 300 moves, its rolling will drive the passive wheel to rotate. This drives the transmission wheel set 305 to rotate and transmit torque to the leveler 302. Here, the design of the active wheel on the force wheel set 304 can be that the roller and the pulley are coaxial, the roller rolls in contact with the table of the paving platform 100, and the pulley is driven and connected to the passive wheel, and the passive wheel is also a pulley.

[0032] like Figure 6 As shown, one end of the leveler 302 is connected to a rotating wheel 1 3023, a groove 3021 is provided in the middle of the leveler 302, and one end and the middle of the transmission wheel group 305 are fixedly sleeved with a rotating wheel 2 3051 that can be rollingly connected with the rotating wheel 1 3023 and the groove 3021; The rotating wheel 3023 and the groove 3021 are coaxial and have the same circular diameter.

[0033] The second wheel 3051 rolls synchronously with the groove 3021 and the first wheel 3023, so that the second wheel 3051 can drive the leveler 302 to rotate and store force. The first wheel 3023 and the groove 3021 are coaxial and have the same diameter to ensure that the force applied by the two second wheels 3051 to the leveler 302 is uniform, which is necessary.

[0034] like Figure 8 and Fig. 9 As shown, the leveler 302 also includes a rotating shaft 3024 fixedly connected to the rotating arms 3022 on both sides, and the rotating shaft 3024 is used to control the rotating arms 3022 on both sides to rotate synchronously; The other end of the leveler 302 is coaxially connected with a ratchet 3025, and the rotating arm 3022 is provided with a ratchet 3026 which can engage with the ratchet 3025 and thus control the ratchet 3025 to rotate in only one direction; There is a slide table 3027 at the end of the rotating arm 3022, and both ends of the leveler 302 are installed on the slide table 3027 for synchronous lifting and lowering with the slide table 3027.

[0035] In this embodiment, the elastic force of the spring 3029 after the power is stored is preserved by the cooperation of the ratchet 3025 and the ratchet 3026, so as to prevent the elastic force from being completely released when the leveler 302 reaches the top of the cloth. In the process of the leveler 302 returning to the cloth layer, the ratchet 3025 and the ratchet 3026 are in a locked state. When the leveler 302 reaches the top of the cloth, the slide 3027 is controlled to move upward relative to the rotating arm 3022, thereby driving the ratchet 3025 to move upward and disengage from the ratchet 3026, so that the leveler 302 body can rotate to level the cloth. The displacement of the slide 3027 relative to the rotating arm 3022 can be achieved in an active or passive manner, and the specific design is made according to the working environment. The specific method is not limited in this embodiment.

[0036] like Figure 8 and Fig. 9 As shown, an elastic member 3028 is elastically connected to the slide 3027, and the elastic member 3028 is used to elastically support the slide 3027 downward.

[0037] When the leveler 302 that has accumulated power is put back on the cloth, since the body of the leveler 302 is in contact with the cloth, the rotating arms 3022 installed on both sides of the body of the leveler 302 will automatically compress the elastic member 3028 to contract, causing the ratchet 3025 to move upward along with the slide 3027, thereby disengaging the ratchet 3025 and the ratchet tooth 3026 from the engagement relationship. Therefore, the power-accumulating spring 3029 can release its elastic force, driving the body of the leveler 302 to rotate, and the leveler 302 starts to level the cloth.

[0038] like Figure 8 As shown, a rubber layer is provided on the outer periphery of the second rotating wheel 3051 , and the rubber layer can only rotate along with the second rotating wheel 3051 in the direction of axially storing force for the leveler 302 , and will slip with the second rotating wheel 3051 if it rotates in the opposite direction.

[0039] This is one embodiment of the second rotating wheel 3051. The purpose of such a configuration is to enable the outer periphery of the second rotating wheel 3051 to drive the leveler 302 to rotate synchronously in the initial first stage, i.e., during the force accumulation movement of the leveler 302. However, in the second stage, i.e., during the return of the fixed plate 301, the force-applying wheel set 304 is still in rolling contact with the table surface, so its reverse rotation will cause rotational conflict with the leveler 302 that has been locked and not rotated by the ratchet 3025 and the ratchet teeth 3026. Therefore, the outer periphery of the second rotating wheel 3051 can be coated with a rubber layer that can only rotate in one direction, and the configuration form can be a structure in which there is a forward and reverse tooth rotation between the rubber layer and the outer periphery of the second rotating wheel 3051.

[0040] In other embodiments of the present application, it is assumed that the outer side of the second rotating wheel 3051 is not provided with a rubber layer, and sliding friction is used to overcome the conflict phenomenon.

[0041] like Figure 6-8 As shown in FIG. 10 , a spring rod 307 is also installed on the cloth-laying platform 100 , and one end of the spring rod 307 is supported on the fixed plate 301 to push it back to the initial position.

[0042] The spring rod 307 here is used to push the flattening assembly 300 as a whole to finally return to the initial position. When its elasticity acts on the flattening assembly 300 of the cloth spreading machine body 200, the cloth spreading machine body 200 props up the rotating arm 3022 and its elastic compression does not appear until the second wheel 3051 and the groove 3021 and the first wheel 3023 roll and squeeze, the spring rod 307 begins to compress, and the fixed plate 301 begins to slide backward along the slide rail 306, causing the active wheel on the force wheel group 304 to roll with the surface of the cloth spreading platform 100, driving the transmission wheel group 305 to rotate and accumulate force on the leveler 302. When the cloth spreading machine body 200 cuts the cloth and puts down the new cloth and moves in another direction, the spring rod 307 synchronously props up the fixed plate 301 and other components thereon to return.

[0043] like Figure 1-4 As shown, top plates 2021 are welded on both sides of the guide plate 202. When the paving machine body 200 moves to the flattening assembly 300, the top plates 2021 are supported on the end of the rotating arm 3022 to drive the leveler 302 to rotate and lift up.

[0044] The top plate 2021 is a protruding portion on the second guide plate 202, which extends out to contact the top support of the rotating arm 3022, and can avoid large-area compression between the surface of the second guide plate 202 and the body surface of the leveler 302, thereby reducing the resistance to the rotation of the leveler 302. The top plate 2021 can be set to a plate of various shapes, including but not limited to a triangle, a polygon, or a curved surface with an arc transition curve, and can be set according to actual needs.

[0045] The working principle and use process of the present invention: The cloth spreading machine body 200 moves to one end of the cloth spreading platform 100, pushing the flattening assembly 300 there to move a small distance, temporarily breaking away from the pressing of the cloth so as to put down new cloth. After the cloth spreading machine body 200 is evacuated, the flattening assembly 300 is supported by the spring rod 307 to return to the work station, and in the process of going back and forth, it rotates and accumulates power for the leveler 302 and locks it. After being lowered above the cloth, the leveler 302 can press the cloth on the one hand, and on the other hand, it can be unlocked and start to rotate to flatten the cloth.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
