Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliance manufacturing, and more specifically to a length folding system of a clothes folding machine. Background Art

[0002] In the related art, a folding machine is disclosed, such as patent document CN112746477A, ​​which specifically discloses a clothes conveying mechanism for conveying clothes after transverse folding and performing at least one longitudinal folding on the clothes. The clothes conveying mechanism includes an upper clothes conveying mechanism and a lower clothes conveying mechanism, wherein the lower clothes conveying mechanism includes a first clothes conveying mechanism and a second clothes conveying mechanism, and the first clothes conveying mechanism and the second clothes conveying mechanism need to further cooperate with mechanical structures such as a first lifting drive assembly and a first translation drive assembly to achieve their longitudinal folding requirements. In addition, patent document CN111433403A discloses a household compact article folding machine with a holding conveyor, specifically discloses a first, second and third main conveyors, and at least two of them are in a stacking form, but actually only discloses 3 embodiments in a stacking form, and also includes a first and a second holding conveyor, each holding conveyor includes at least three holding rollers, and at the same time needs to further cooperate with at least a first length folder to be configured in the article to form a length folding layer.

[0003] It can be seen that the length folding system of the existing clothes folding machine either has many levels, which takes up a lot of space vertically, or needs to be equipped with many mechanical components, which makes the overall structure complicated, affects the miniaturization design of the whole machine, and is not convenient to promote to household use. Utility Model Content

[0004] The utility model aims to overcome at least one defect of the above-mentioned prior art, and aims to provide a length folding system of a clothes folding machine, which is used to solve the problems of complex structure and large space size.

[0005] The technical solution adopted by the utility model is to provide a length folding system of a clothes folding machine, including a frame and a first conveying mechanism and a first clothes clamping mechanism arranged on the frame, the first clothes clamping mechanism corresponds to the middle and rear part of the first conveying mechanism and can be raised and lowered relative to the upper surface of the first conveying mechanism, the first conveying mechanism conveys the clothes backwards and cooperates with the first clothes clamping mechanism to clamp the clothes located on the surface of the first conveying mechanism to perform a length folding on the clothes.

[0006] In the present scheme, the first clothing clamping mechanism is arranged as a whole above the first conveying mechanism, and the first conveying mechanism conveys the clothing forward through the space where the first clothing clamping mechanism is located and continues to convey it forward. When the clothing is conveyed to the first preset position, the first conveying mechanism stops conveying, and the first clothing clamping mechanism clamps a part of the clothing downward and lifts the part of the clothing. At this time, a first length folding space is formed between the clothing brought up by the first clothing clamping mechanism and the first conveying mechanism located below the rear side of the first clothing conveying mechanism; thereafter, the first conveying mechanism is started to continuously convey the clothing backward, and the clothing located in front of the first clothing clamping mechanism passes through the first length folding space for length folding, until the clothing is conveyed backward to the second preset position, the first conveying mechanism stops running, the first clothing clamping mechanism releases the clothing and stays above the first conveying mechanism, and the clothing completes one length folding. The clothing length folding system of the present invention can complete the entire process of folding clothing in length only through the cooperation of the mechanisms on the same layer, which greatly reduces the longitudinal size of the length folding system and contributes to the miniaturization design of the entire clothes folding machine. At the same time, the length folding system of the present invention can be realized only through the cooperation of the first conveying mechanism and the first clothing clamping mechanism, and the mechanical structure is simple, which greatly reduces the structural complexity of the clothes folding machine equipped with the length folding system.

[0007] Furthermore, a first pressing mechanism installed on a frame is provided above the first conveying mechanism located on the rear side of the first clothing clamping mechanism, and the first pressing mechanism can be adjusted up and down relative to the upper surface of the first conveying mechanism, and / or a second pressing mechanism installed on the frame is provided above the first conveying mechanism located on the front side of the first clothing clamping mechanism, and the second pressing mechanism can be adjusted up and down relative to the upper surface of the first conveying mechanism.

[0008] This solution adjusts the first pressing mechanism and the second pressing mechanism to press the clothes down against the upper surface of the first conveying mechanism, thereby increasing the friction between the clothes and the first conveying mechanism during the conveying process, and making the conveying process reliable. In particular, when the clothes are folded in length, the first clothes clamping mechanism clamps the clothes and lifts them, which will cause the pressure of the clothes on the first conveying mechanism to be significantly reduced, which may have an adverse effect on the reliability of the clothes when they are conveyed forward and backward. At this time, the first pressing mechanism and the second pressing mechanism of this solution continue to press the clothes down against the upper surface of the first conveying mechanism, so that the clothes and the surface of the first conveying mechanism maintain sufficient downward pressure, thereby avoiding the problem of insufficient friction between the clothes and the upper surface of the first conveying mechanism. In addition, the pressing mechanism can also continuously compress the thickness of the clothes, thereby improving the flatness of the clothes.

[0009] Optionally, the first pressing mechanism is a first pressing roller device, and / or the second pressing mechanism is a second pressing roller device.

[0010] The first pressing roller device and / or the second pressing roller device presses down on the clothes. When the clothes are transported back and forth, the friction of the upper surface of the clothes drives the rollers of the corresponding pressing roller devices to roll to continuously press down the clothes. At the same time, since there is rolling contact between the roller component and the upper surface of the clothes, the friction resistance during the relative movement between the two can be reduced, thereby ensuring that the conveying mechanism conveys the clothes continuously and smoothly.

[0011] Optionally, the first pressing roller device includes a first roller and a pair of first support seats for supporting and setting the first roller, the first support seats are respectively arranged on the frames on both sides of the first conveying mechanism, and the first roller is configured to be movable relative to the first support seat so as to adjust its own position up and down relative to the upper surface of the first conveying mechanism. Preferably, an oblong hole is provided on the support seat, and the two ends of the first roller are supported and set in the oblong holes; and / or, the second pressing roller device includes a second roller and a pair of second support seats for supporting and setting the second roller, the second support seats are respectively arranged on the frames on both sides of the first conveying mechanism, and the second roller is configured to be movable relative to the second support seat so as to adjust its own position up and down relative to the upper surface of the first conveying mechanism. Preferably, the second support seats are respectively arranged on the frames on both sides, and the second support seats are provided with oblong holes.

[0012] In this solution, the roller of the pressure roller device is adjusted up and down through the oblong hole on the support seat, so that the appropriate downward pressure amplitude can be adjusted for different clothes to achieve efficient front and back conveying of clothes.

[0013] Optionally, the support seats are all bearing support seats.

[0014] In some embodiments, the first conveying mechanism includes a front conveying device and a rear conveying device connected with each other in a front-to-rear gap, and the first clothing clamping mechanism is located between the front conveying device and the rear conveying device.

[0015] In this solution, the gap between the front conveying device and the rear conveying device can be used to arrange the first clothing clamping mechanism. In this case, at least two settings of the first clothing clamping mechanism can be realized. In the first case, the first clothing clamping mechanism can be arranged to be located above the first conveying mechanism as a whole. When it is necessary to clamp clothing, the first clothing clamping mechanism descends to the surface of the clothing to clamp the clothing, and then lifts up the clothing. In the second case, the first clamping mechanism can be provided with a matching upper part and a lower part, the lower part is located in the gap between the front conveying device and the rear conveying device, and the upper part is located above the first conveying mechanism. When it is necessary to clamp clothing, the lower part rises to bring the clothing and clamps it to the upper part. In the second case, when it is not necessary to clamp clothing, the lower part of the first clothing clamping mechanism is hidden in the gap, which will not hinder the forward and backward transportation of clothing. When it is necessary to clamp clothing, the clothing is lifted up from the lower surface of the clothing, which has better clamping stability, and only needs to be lifted once to clamp clothing, and can avoid the adverse effect on the flatness of the clothing surface when the clothing is clamped downward in the first case.

[0016] Furthermore, a first pressing mechanism installed on the frame is provided above the rear conveying device, and the first pressing mechanism can be adjusted up and down relative to the upper surface of the rear conveying device; and / or, a second pressing mechanism installed on the frame is provided above the front conveying device, and the second pressing mechanism can be adjusted up and down relative to the upper surface of the front conveying device.

[0017] In the process of conveying clothes forward and backward, the present solution can continuously press the clothes against the surface of the conveying mechanism through the pressing mechanism, increase the friction between the clothes and the surface of the conveying mechanism, and thus improve the reliability of the conveying process. At the same time, the continuous pressing can also reduce the thickness of the clothes, which plays a role in flattening the clothes. In particular, when folding the clothes in length, the first clothes clamping mechanism clamps the clothes and lifts the clothes upward. During this process, the clothes tend to separate from the surface of the conveying mechanism. In the present solution, the first pressing mechanism and / or the second pressing mechanism apply pressure on the surface of the clothes, so that the clothes always maintain sufficient friction with the conveying mechanism when folding the clothes in length.

[0018] Further, the rear conveying device is a first conveying crawler device, and / or the front conveying device is a second conveying crawler device.

[0019] Optionally, the first conveying crawler device comprises a first crawler component and a drive assembly, and the first crawler component is arranged on the frame, and / or the second conveying crawler device comprises a second crawler component and a drive assembly, and the second conveying crawler component is arranged on the frame.

[0020] Optionally, the first track component includes a first track and at least one pair of first traction rollers movably arranged on two side frames, and the pair of first traction rollers are respectively arranged at two ends of the inner side of the first track to cooperate in traction of the first track, and / or, the second track component includes a second track and at least one pair of second traction rollers movably arranged on two side frames, and the pair of second traction rollers are respectively arranged at two ends of the inner side of the second track to cooperate in traction of the second track.

[0021] Optionally, the first crawler is a flexible crawler, and / or the second crawler is a flexible crawler.

[0022] When the pressure roller device presses the clothes down on the surface of the conveying mechanism through the flexible track, the surface of the conveying mechanism has a certain self-adjustment ability and can adapt to the downward pressure of the pressure roller device within a certain range, thereby ensuring sufficient friction between the clothes and the surface of the conveying mechanism while avoiding the clothes from being stuck between the conveying mechanism and the pressure roller device.

[0023] Optionally, the rear conveying device and the front conveying device are driven by the same set of driving components.

[0024] Driven by the same set of driving components, the rear conveying device and the front conveying device realize synchronous and unidirectional conveying, and also reduce the overall structural complexity of the clothing feeding system.

[0025] Optionally, the driving assembly includes a first motor and a first pulley assembly, the first pulley assembly is provided with a first synchronous belt and at least three first gears, wherein the first motor, the front traction roller of the first conveying crawler device, and the rear traction roller of the second conveying crawler device are all provided with at least one first gear and are meshed and driven by the first synchronous belt.

[0026] Furthermore, a second conveying mechanism and a second clothing clamping mechanism are provided, wherein at least a portion of the second conveying mechanism is located in front of the first conveying mechanism, and the second clothing clamping mechanism is located between the first conveying mechanism and the second conveying mechanism and can be raised and lowered relative to the upper surface of the first conveying mechanism; the first conveying mechanism and the second conveying mechanism convey the clothing forward and cooperate with the second clothing clamping mechanism to fold the clothing once in length.

[0027] In the present scheme, during the process of the first and second conveying mechanisms cooperating to convey the clothes backward, when the clothes move to the third preset position, the first and second conveying mechanisms stop running, the second clothes clamping mechanism clamps the clothes and lifts them upward, at which time a second length folding space is formed between the clothes clamped by the second clothes clamping mechanism and the surface of the conveying mechanism below; then, the first and second conveying mechanisms are restarted to convey the clothes forward, and the clothes are folded in length once through the second length folding space, until the clothes are conveyed forward to the fourth preset position, the first and second conveying mechanisms stop running, the second clothes clamping mechanism releases the clothes and stays above the first conveying mechanism, at which time the clothes complete one length folding.

[0028] Optionally, the second conveying mechanism is located in front of the first conveying mechanism, and a rear edge of the second conveying mechanism is gap-connected with a front edge of the first conveying mechanism.

[0029] In this solution, clothes can be efficiently transported back and forth between the first conveying mechanism and the second conveying mechanism, and the second conveying mechanism continues to transport the clothes forward to send the clothes out of the length folding system. At this time, the device corresponding to the storage process can be correspondingly arranged in front of the second conveying mechanism.

[0030] Optionally, the second conveying mechanism is arranged to be gradually inclined upward from below the first conveying mechanism to the front of the first conveying mechanism.

[0031] In this solution, when conveying clothes forward, the clothes conveyed by the first conveying mechanism fall from the rear edge of the first conveying mechanism to the front edge of the second conveying mechanism, and then the second conveying mechanism drives the clothes to continue to be conveyed forward; when the clothes complete the length folding process, the clothes are located as a whole on the upper surface of the second conveying mechanism, and then the clothes are conveyed backward by the second conveying mechanism to make the clothes out of the length folding system. At this time, the device corresponding to the storage process can be arranged under the first conveying mechanism, without occupying additional space in the front and rear directions, which is conducive to the miniaturization of the overall layout of the machine.

[0036] Optionally, the third support seat is a bearing support seat.

[0037] Optionally, the third conveying crawler device includes a third crawler component and a transmission assembly for driving the third crawler component.

[0038] Optionally, the third track components include a third track and at least one pair of third traction rollers movably arranged on the frame, and the pair of third traction rollers are respectively located at two ends of the inner side of the third track to cooperate in traction of the third track.

[0039] Optionally, the transmission assembly is a second pulley assembly, which is provided with a second synchronous belt and two second gears. The two second gears are respectively arranged on the front traction roller of the second conveying crawler device and the rear traction roller of the third conveying crawler device and are both meshed and driven by the third synchronous belt.

[0040] Further, the first clothing clamping mechanism includes a first clamping assembly and a first clamping drive device, and the first clamping drive device drives the first clamping assembly to be adjusted up and down relative to the upper surface of the first conveying mechanism to clamp the clothing conveyed on the first conveying mechanism; preferably, the first clamping assembly includes a matching first upper clamping part and a first lower clamping part, and the first upper clamping part is located above the first conveying mechanism, and the first clamping drive device drives the first lower clamping part to be adjusted up and down relative to the upper surface of the first conveying mechanism to cooperate with the first upper clamping part to clamp the clothing conveyed on the first conveying mechanism.

[0041] Further, the first clothing clamping mechanism includes a first clamping assembly and a first clamping drive device both installed on the frame, the first clamping assembly is located between the front conveying device and the rear conveying device, and the first clamping drive device drives the first clamping assembly to be adjusted up and down relative to the upper surfaces of the front conveying device and the rear conveying device to clamp the clothing; preferably, the first clamping assembly includes a first upper clamping part and a first lower clamping part that cooperate with each other, the first upper clamping part is located above the first conveying mechanism, and the first clamping drive device drives the first lower clamping part to be adjusted up and down relative to the upper surface of the first conveying mechanism to cooperate with the first upper clamping part to clamp the clothing conveyed on the first conveying mechanism.

[0042] In the present solution, the lower clamping part that can be raised and lowered and adjusted can be lowered into the gap between the two conveying mechanisms when in a non-clamping state, so as to avoid obstruction of the lower clamping part when the clothes are conveyed forward and backward. When the clothes need to be clamped, the corresponding clamping drive device drives the corresponding lower clamping part to rise and lift the clothes and finally clamp the clothes between the upper clamping part and the lower clamping part. At this time, a length folding space is formed under the clothes clamping mechanism that clamps the clothes, and the conveying mechanism continuously transports the clothes through the length folding space for length folding.

[0043] Preferably, the first clamping drive device is an electromagnetic locking mechanism, which includes an electromagnetic generating part and an electromagnetic matching part, and the electromagnetic generating part and the electromagnetic matching part are respectively arranged on the first upper clamping part and the first lower clamping part. Optionally, the lowest point of the lifting adjustment of the first lower clamping part is located below the upper surface of the first conveying mechanism.

[0044] Furthermore, the second clothing clamping mechanism includes a second clamping assembly and a second clamping drive device both mounted on the frame, the second clamping assembly being located between the first conveying mechanism and the second conveying mechanism, and the second clamping drive device driving the second clamping assembly to be adjustable up and down relative to the upper surface of the first conveying mechanism to clamp clothing; preferably, the second clamping assembly includes a second upper clamping portion and a second lower clamping portion that cooperate with each other, the second upper clamping portion being located above and in front of the first conveying mechanism, and the second clamping drive device driving the second lower clamping portion to be adjustable up and down relative to the upper surface of the first conveying mechanism to cooperate with the second upper clamping portion to clamp clothing conveyed on the first conveying mechanism and the second conveying mechanism.

[0047] When the first clothing clamping mechanism or the second clothing clamping mechanism clamps the clothing, the "V"-shaped groove of the present scheme cooperates with the rotating member to form a larger clamping area for the clothing and obtain a reliable clamping force. In addition, when the clamped clothing portion needs to change direction, the clothing can be rotated around the rotating member as the axis to achieve this.

[0048] Optionally, the first clothing clamping mechanism is further provided with an elastic member connected between the upper clamping part and the lower clamping part.

[0049] When the corresponding clothing clamping mechanism stops clamping the clothing, the elastic member accelerates the separation between the clamping portion and the lower clamping portion, so that the clothing clamping mechanism quickly returns to a non-clamping state.

[0050] Optionally, the elastic member is provided in a group, and the elastic member in the group is respectively connected to the two ends of the upper clamping part and the lower clamping part.

DETAILED DESCRIPTION

[0061] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0062] For the convenience of explanation, the left and right directions of the drawings of the present invention correspond to the rear and front directions described in the embodiments based on the viewing angle, respectively.

[0063] Example 1

[0064] like Figure 1 , Figure 2 As shown, the present embodiment provides a length folding system 11 of a clothes folding machine 1, comprising a frame 12 and a first conveying mechanism 100 and a first clothes clamping mechanism 400 arranged on the frame 12, the first clothes clamping mechanism 400 corresponds to the middle and rear part of the first conveying mechanism 100 and can be raised and lowered relative to the upper surface of the first conveying mechanism 100, the first conveying mechanism 100 conveys clothes backwards and cooperates with the first clothes clamping mechanism 400 to clamp the clothes located on the surface of the first conveying mechanism 100 to perform a length folding on the clothes.

[0065] During implementation, the first clothing clamping mechanism 400 of this embodiment is located as a whole above the first conveying mechanism 100. During specific implementation, the first clothing clamping mechanism 400 of this embodiment can be a clamp-like device to downwardly grab the clothing conveyed by the first conveying mechanism 100. During the process of the first conveying mechanism 100 conveying the clothing forward, when the clothing is conveyed forward to the first preset position, the first conveying mechanism 100 stops conveying, and the first clothing clamping mechanism 400 clamps a part of the clothing downward and lifts the part of the clothing. At this time, a first length folding space is formed between the first clothing clamping mechanism 400 and the upper surface of the first conveying mechanism 100 located at the rear side of the first clothing clamping mechanism 400 below; thereafter, the first conveying mechanism 100 is started to continuously convey the clothing backward, and the clothing passes through the first length folding space for length folding until the clothing is conveyed backward to the second preset position, and the first conveying mechanism 100 stops running, and the first clothing clamping mechanism 400 releases the clothing and stays above the first conveying mechanism 100, and the clothing completes one length folding. The entire process of folding the length of clothing by the clothing length folding system 11 of the present invention can be completed only through the cooperation of the mechanisms on the same layer, which greatly reduces the longitudinal size of the length folding system 11 and contributes to the miniaturization design of the entire folding machine 1. At the same time, the length folding system 11 of the present invention can be realized only through the cooperation of the first conveying mechanism 100 and the first clothing clamping mechanism 400, and the mechanical structure is simple, which greatly reduces the structural complexity of the folding machine 1 provided with the length folding system 11.

[0066] In specific implementation, the first preset position can be flexibly adjusted according to the actual folding effect to be achieved or when facing different clothes. In order to fully fold the clothes in the length direction, it is usually required that when the clothes are conveyed to the first preset position, at least 1 / 2 of the length of the clothes has passed through the first clothes clamping mechanism 400 corresponding to the position on the first conveying mechanism 100. In a preferred embodiment, when the clothes are conveyed forward to the first preset position, it can correspond to the rear end of the clothes just passing under the first clothes clamping mechanism 400, and the first clothes clamping mechanism 400 can clamp the rear end of the clothes accordingly. After that, when the clothes are continuously conveyed backward for folding, the clothes located in front of the first clothes clamping mechanism 400 can be folded to the first length space according to actual needs to form a sufficient length fold.

[0067] In addition, during specific implementation, the second preset position can be flexibly adjusted according to the actual folding effect to be achieved or when facing different clothes, especially when other conveying mechanisms are connected to the rear of the first conveying mechanism 100 and other clothing clamping mechanisms are configured, the position of the clothes at the second preset position needs to be adjusted accordingly to obtain a good folding effect. In some embodiments, when the clothes are conveyed to the second preset position, the front end of the corresponding clothes can be folded just below the first clothing clamping mechanism 400 in the raised state, and the clothes are just folded once.

[0068] In a specific implementation, in order to accurately detect the above-mentioned first preset position and the second preset position, a number of sensors can also be set on the first conveying mechanism 100, and the distance traveled by the clothes can be detected by the sensors. By controlling the sensors, the first conveying mechanism 100, and the first clothes clamping mechanism 400 through the control system of the clothes folding machine 1, the length folding system 11 can perform corresponding operations at the first preset position and the second preset position.

[0069] like Figure 1 , Figure 2 As shown, a first pressing mechanism 500 installed on the frame 12 is provided above the first conveying mechanism 100 located at the rear side of the first clothing clamping mechanism 400, and the first pressing mechanism 500 can be adjusted up and down relative to the upper surface of the first conveying mechanism 100. A second pressing mechanism 600 installed on the frame 12 is provided above the first conveying mechanism 100 located at the front side of the first clothing clamping mechanism 400, and the second pressing mechanism 600 can be adjusted up and down relative to the upper surface of the first conveying mechanism 100.

[0070] When conveying clothes forward and backward, the first pressing mechanism 500 and the second pressing mechanism 600 press the clothes downward against the upper surface of the first conveying mechanism 100, thereby increasing the friction between the clothes and the first conveying mechanism 100 and making the conveying process reliable. In particular, when folding the clothes in length, the first clothes clamping mechanism 400 clamps the clothes and lifts them, which will cause the pressure of the clothes on the first conveying mechanism 100 to be significantly reduced, which will have an adverse effect on the reliability of conveying clothes forward and backward. At this time, the first pressing mechanism 500 and the second pressing mechanism 600 continue to press the clothes down against the upper surface of the first conveying mechanism 100, thereby avoiding the problem of insufficient friction between the clothes and the upper surface of the first conveying mechanism 100. In addition, the pressing mechanism can also continuously compress the thickness of the clothes, thereby improving the flatness of the clothes.

[0071] The first pressing mechanism 500 is a first pressing roller device, and the second pressing mechanism 600 is a second pressing roller device.

[0072] When conveying clothes back and forth, the first pressing roller device and / or the second pressing roller device presses down on the clothes, and the friction of the upper surface of the clothes drives the rollers of the corresponding pressing roller devices to roll to continuously press down the clothes. At the same time, since there is rolling contact between the roller components and the upper surface of the clothes, the friction resistance between the two during relative movement can be reduced, thereby ensuring that the conveying mechanism conveys clothes continuously and smoothly.

[0073] like Figure 1 , Figure 2 As shown, the first pressing roller device includes a first roller 510 and a pair of first support seats 520 for supporting the first roller 510. The first support seats 520 are respectively arranged on the frame 12 on both sides of the first conveying mechanism, and an oblong hole is opened on the first support seats 520.

[0074] Similarly, in a specific implementation, the second pressing roller device may also include a second roller 610 and a pair of second support seats 620 for supporting the second roller 610. The second support seats 620 are respectively arranged on the frame 12 on both sides of the first conveying mechanism, and an oblong hole is opened on the second support seats 620.

[0075] When working, the roller of the pressing roller device is adjusted up and down through the oblong hole on the support seat, so that the appropriate downward pressure amplitude can be adjusted for different clothes to achieve efficient front and back conveying of clothes. In specific implementation, in order to achieve better support effect, the first support seat 520 and the second support seat 620 are both bearing support seats.

[0076] In addition, during the specific implementation, the first conveying mechanism 100 is a conveying crawler device, and more preferably a conveying crawler device with a flexible crawler is used, so as to cooperate with the first pressure roller device and the second pressure roller device to achieve appropriate downward pressure on the surface of the clothes. On the one hand, it can ensure that there is sufficient friction between the lower surface of the clothes and the upper surface of the first conveying mechanism 100 to reliably convey the clothes. On the other hand, the rolling downward pressure of the pressure roller device can avoid excessive friction resistance between the upper surface of the clothes and the pressure roller device.

[0077] When this embodiment is used specifically, first, the first conveying mechanism 100 conveys the clothes forward, and the first pressing roller device and the second pressing roller device always press the clothes on the upper surface of the first conveying mechanism 100. When the rear end of the clothes just passes through the position of the first clothes conveying mechanism 400 corresponding to the upper surface of the first conveying mechanism 100, the first conveying mechanism 100 stops conveying; then, the first clothes clamping mechanism 400 clamps the rear end of the clothes and lifts them to the top of the first conveying mechanism 100, and a first length folding space is formed between the first clothes clamping mechanism 400 and the upper surface of the first conveying mechanism 100 located at the rear side of the first clothes clamping mechanism 400; thereafter, the first conveying mechanism 100 is started to continuously convey the clothes backward, and the clothes located at the front side of the first clothes clamping mechanism 400 pass through the first length folding space backward to be folded in length, until the front end of the clothes is folded to the bottom of the first conveying mechanism 400, the first conveying mechanism 100 stops running, the first clothes clamping mechanism 400 releases the clothes and stays above the first conveying mechanism 100, and the clothes are folded in half in the length direction.

[0078] Example 2

[0079] like Figure 1 , Figure 3 As shown, the first conveying mechanism 100 of this embodiment includes a front conveying device 300 and a rear conveying device 200 connected with a front-to-back gap, and the first clothing clamping mechanism 400 is located between the front conveying device 300 and the rear conveying device 200. During implementation, the front conveying device 300 and the rear conveying device 200 are both horizontally arranged.

[0080] In this embodiment, if Figure 3 As shown, a first pressing mechanism 500 is correspondingly arranged above the rear conveying device 200, and the first pressing mechanism 500 can be adjusted up and down relative to the upper surface of the rear conveying device 200; a second pressing mechanism 600 is correspondingly arranged above the front conveying device 300, and the second pressing mechanism 600 can be adjusted up and down relative to the upper surface of the rear conveying device 200.

[0081] In a specific implementation, the rear conveying device 200 is a first conveying crawler device, and the front conveying device 300 is a second conveying crawler device.

[0082] like Figure 3-6 As shown, the first conveying crawler device includes a first crawler component and a driving assembly 230, and the first crawler component is arranged on the frames 12 on both sides. The second conveying crawler device includes a second crawler component and a driving assembly 230, and the second crawler component is arranged on the frames 12 on both sides.

[0083] Among them, the first track component includes a first track 210 and at least one pair of first traction rollers 220 movably arranged on the two side frames 12, and the pair of first traction rollers 220 are respectively arranged at the two ends of the inner side of the first track 210 to cooperate with traction of the first track 210; the second track component includes a second track 310 and at least one pair of second traction rollers 320 movably arranged on the two side frames 12, and the pair of second traction rollers 320 are respectively arranged at the two ends of the inner side of the second track 310 to cooperate with traction of the second track 310.

[0084] In a preferred embodiment, the first track 210 is a flexible track, and the second track 310 is a flexible track. When the pressure roller device presses the clothes down on the surface of the conveying mechanism, the flexible track has a certain self-adjustment ability and can adapt to the downward pressure of the pressure roller device within a certain range, thereby ensuring that there is sufficient friction between the clothes and the surface of the conveying mechanism while avoiding the clothes from being stuck between the conveying mechanism and the pressure roller device. The flexible track can also protect the conveyed clothes from damage.

[0085] like Figure 3 , Figure 5 As shown, the rear conveying device 200 and the front conveying device 300 are driven by the same set of driving components 230 .

[0086] Since a group of driving components 230 are used to drive the operation, the rear conveying device 200 and the front conveying device 300 can realize synchronous and unidirectional conveying, and also reduce the overall structural complexity of the clothing feeding system.

[0087] Among them, the driving component 230 includes a first motor 231 and a first pulley component 232, the first pulley component 232 is provided with a first synchronous belt 232a and at least three first gears 232b, wherein the first motor 231, the front traction roller of the first conveying crawler device, and the rear traction roller of the second conveying crawler device are all provided with at least one first gear 232b and are meshed and driven by the first synchronous belt 232a.

[0088] like Figure 3-6 As shown, a second conveying mechanism 700 and a second clothing clamping mechanism 800 are also provided. The second conveying mechanism 700 is arranged to be gradually inclined upward from the bottom of the front conveying device 300 to the front of the front conveying device 300. The second clothing clamping mechanism 800 is located between the first conveying mechanism 100 and the second conveying mechanism 700 and can be raised and lowered relative to the upper surface of the first conveying mechanism 100. The first conveying mechanism 100 and the second conveying mechanism 700 convey the clothing forward and cooperate with the second clothing clamping mechanism 800 to fold the clothing once in length.

[0089] During operation, the rear conveying device 200, the front conveying device 300, and the second conveying mechanism 700 cooperate to convey the clothes backward. When the clothes move to the third preset position, the rear conveying device 200, the front conveying device 300, and the second conveying mechanism 700 stop running, and the second clothes clamping mechanism 800 clamps the clothes and lifts them to the top between the front conveying device 300 and the second conveying mechanism 700. At this time, a second length folding space is formed between the second clothes clamping mechanism 800 and the upper surface of the second conveying mechanism 700 below; then, the rear conveying device 200, the front conveying device 300, and the second conveying mechanism 700 are restarted to convey the clothes forward instead, and the clothes located at the rear side of the second clothes clamping mechanism 800 are folded forward into the second length folding space until the clothes are conveyed forward to the fourth preset position, the rear conveying device 200, the front conveying device 300, and the second conveying mechanism 700 stop running, and the second clothes clamping mechanism 800 releases the clothes and stays above between the front conveying device 300 and the second conveying mechanism 700, and the clothes complete one length folding.

[0090] During specific implementation, the third preset position can be flexibly adjusted according to different actual folding requirements or when facing different clothes. In a preferred embodiment, the third preset position can correspond to the position where the front end of the clothes is just transported backward through the second clothes clamping mechanism 800, and the second clothes clamping mechanism 800 can clamp the front end of the clothes, which is conducive to fully folding the clothes in the length direction. The fourth preset position can also be flexibly adjusted according to different actual folding requirements or when facing different clothes. In a preferred embodiment, the fourth preset position can correspond to the position where the rear end of the clothes is transported forward and completely folded to the bottom of the second clothes clamping mechanism 800. At this time, the rear end of the clothes is just below the front end of the aforementioned clothes. When the second clothes clamping mechanism 800 releases the clothes, the front end of the clothes falls and aligns with the rear end of the clothes, and the clothes are fully folded in the length direction.

[0091] At this time, during specific implementation, this embodiment conveys the clothes forward, and the clothes conveyed by the first conveying mechanism 100 fall from the front edge of the front conveying device 300 to the rear edge of the second conveying mechanism 700. Thereafter, the second conveying mechanism 700 drives the clothes to continue to be conveyed forward; when the clothes complete the length folding process, the clothes are located as a whole on the upper surface of the second conveying mechanism 700, and the clothes can be sent out of the length folding system 11 by continuing to convey the clothes through the second conveying mechanism 700. At this time, a preferred method is that the second conveying mechanism 700 continues to convey the clothes backward to send the clothes out of the length folding system 11, and the subsequent storage process or the corresponding device for the further folding process can be arranged below the front conveying device 300, without occupying additional space in the front and rear directions, which is conducive to the miniaturized layout of the whole machine.

[0092] like Figure 3-6 As shown, a third pressing mechanism 900 installed on the frame 12 is also provided above the second conveying mechanism 700 , and the third pressing mechanism 900 can be adjusted up and down relative to the upper surface of the second conveying mechanism 700 .

[0093] The second conveying mechanism 700 is a third conveying crawler device. The third pressing mechanism 900 is a third pressing roller device.

[0094] like Figure 6 As shown, the third roller device includes a third roller 910 and a pair of third support seats 920 for supporting and setting the third roller 910. The third support seats 920 are respectively arranged on the frames 12 on both sides. The third support seats 920 are provided with oblong holes, and the two ends of the third roller 910 are adjusted up and down in the oblong holes. In specific implementation, the third support seats 920 are bearing support seats.

[0095] like Figure 6 As shown, the third conveying crawler device includes a third crawler component and a transmission assembly for driving the third crawler component.

[0096] The third track components include a third track 710 and at least one pair of third traction rollers 720 movably disposed on the frame 12 , and the pair of third traction rollers 720 are respectively located at both ends of the inner side of the third track 710 to cooperate with traction of the third track 710 .

[0097] like Figure 6 As shown, the transmission assembly is a second pulley assembly 730, and the second pulley assembly 730 is provided with a second synchronous belt 731 and two second gears 732. The two second gears 732 are respectively arranged on the front traction roller of the second conveying crawler device and the rear traction roller of the third conveying crawler device and are both driven by the third synchronous belt.

[0098] like Figure 3 , Figure 4 , Figure 8 As shown, the first clothing clamping mechanism 400 includes a first clamping component 410 and a first clamping drive device 420, and the first clamping drive device 420 drives the first clamping component 410 to be adjusted up and down relative to the upper surface of the first conveying mechanism 100; the second clothing clamping mechanism 800 includes a second clamping component 810 and a second clamping drive device 820, and the second clamping drive device 820 drives the second clamping component 810 to be adjusted up and down relative to the upper surface of the first conveying mechanism 100 and the upper surface of the first conveying mechanism 100.

[0099] The first clamping assembly 410 includes a first upper clamping portion 411 and a first lower clamping portion 412 that match each other. The first upper clamping portion 411 is located above the first conveying mechanism 100. The first clamping driving device 420 drives the first lower clamping portion 412 to be adjusted up and down relative to the upper surface of the first conveying mechanism 100. The second clamping assembly 810 includes a second upper clamping portion 811 and a second lower clamping portion 812 that match each other. The second upper clamping portion 811 is located above the first conveying mechanism 100. The second clamping driving device 820 drives the second lower clamping portion 812 to be adjusted up and down relative to the upper surface of the first conveying mechanism 100. In specific implementation, in order to avoid interference with the clothes transported in front and behind, the lowest point of the first lower clamping portion 412 for adjustment of the lifting and lowering is located below the upper surface of the front conveying device 300 and the rear conveying device 200; the lowest point of the second lower clamping portion 812 for adjustment of the lifting and lowering is located below the upper surface of the front conveying device 300 and the rear conveying device 200.

[0100] In actual applications, when in a non-clamping state, the corresponding lower clamping part can be lowered into the gap between the corresponding two conveying mechanisms, thereby avoiding obstruction of the lower clamping part when the clothes are conveyed back and forth; when in the process of clamping clothes, the corresponding clamping drive device drives the corresponding lower clamping part to rise and lift the clothes and finally clamp the clothes between the upper clamping part and the lower clamping part. At this time, a length folding space is formed under the clothes clamping mechanism that clamps the clothes, and the conveying mechanism continues to transport the clothes through the length folding space for length folding.

[0101] like Figure 3 , Figure 4 , Figure 8 As shown, in a specific implementation, the first clamping drive device 420 is an electromagnetic locking device, which includes an electromagnetic generating part 421 and an electromagnetic matching part 422, and the electromagnetic generating part 421 and the electromagnetic matching part 422 are respectively correspondingly arranged on the first upper clamping part 411 and the first lower clamping part 412; similarly, the second clamping drive device 820 is an electromagnetic locking device, which includes an electromagnetic generating part 421 and an electromagnetic matching part 422, and the electromagnetic generating part 421 and the electromagnetic matching part 422 are respectively correspondingly arranged on the second upper clamping part 811 and the second lower clamping part 812.

[0102] like Figure 8 As shown, the first lower clamping portion 412 is a rotating member with a certain extension length, which is used to cooperate with the extension length of the first conveying mechanism to better clamp the clothes on the first conveying mechanism, and the first upper clamping portion 411 is provided with an inverted "V"-shaped groove 411a that cooperates with the rotating member; similarly, the second lower clamping portion 812 is a rotating member with a certain extension length, which is used to cooperate with the extension length of the first conveying mechanism to better clamp the clothes on the first conveying mechanism, and the second upper clamping portion 811 is provided with an inverted "V"-shaped groove 411a that cooperates with the rotating member.

[0103] It can be understood that when the first clothing clamping mechanism 400 or the second clothing clamping mechanism 800 clamps clothing, the "V"-shaped groove 411a cooperates with the rotating member to form a larger clamping area for the clothing, obtain reliable clamping force, and also form a larger clamping space, which can be adapted to clamp clothing of different thicknesses. In addition, when the clamped clothing part needs to change its direction, the clothing can be rotated around the rotating member as the axis to achieve this.

[0104] When implementing it specifically, Figure 8 As shown, the first clothing clamping mechanism 400 is further provided with an elastic member 430 connected between the upper clamping portion and the lower clamping portion; similarly, the second clothing clamping mechanism 800 is also provided with an elastic member 430 connected between the upper clamping portion and the lower clamping portion;

[0105] When the corresponding clothing clamping mechanism stops clamping the clothing, the elastic member 430 accelerates the separation between the clamping portion and the lower clamping portion, so that the clothing clamping mechanism quickly returns to a non-clamping state.

[0106] In a specific implementation, a group of elastic members 430 is provided, and a group of elastic members 430 is respectively connected to the two ends of the upper clamping part and the lower clamping part.

[0107] When the present embodiment is used, the front conveying device 300 and the rear conveying device 200 are connected and cooperated to continuously convey the clothes forward. After the clothes pass through the first clothes clamping mechanism 400, they continue to be conveyed forward. When the rear end of the clothes just passes through the position of the first clothes clamping mechanism 400 corresponding to the upper surface of the front conveying device 300 and the rear conveying device 200, the front conveying device 300 and the rear conveying device 200 both stop running, and the first clothes clamping mechanism 400 clamps the clothes and lifts them to the upper part between the front conveying device 300 and the rear conveying device 200. At this time, the first clothes clamping mechanism 400 brings up the clothes and connects with the rear conveying device below. A first length folding space is formed on the upper surface of the device 200; then, the front conveying device 300 and the rear conveying device 200 are operated to jointly convey the clothes backward and pass through the first length folding space below the first clothes clamping mechanism 400 to perform a length folding, until the front end of the clothes just passes the front edge of the front conveying device 300. At this time, the first and second conveying crawler devices stop running, the first clothes clamping mechanism 400 releases the clothes and stays above the first conveying mechanism, and the rear end of the clothes falls on the clothes surface located on the upper surfaces of the rear conveying device 200 and the front conveying device 300, and the clothes complete the first length folding.

[0108] Afterwards, the second clothing clamping mechanism 800 clamps the front end of the clothing just passing through the front edge of the front conveying device 300 and lifts it, and at this time, a second length folding space is formed between the second clothing clamping mechanism 800 and the upper surface of the second conveying mechanism 700 below; then, the rear conveying device 200, the front conveying device 300 and the second conveying mechanism 700 cooperate to continue to convey the clothing that has been folded in length for the first time forward, and the clothing passes through the second length folding space and falls on the second conveying mechanism 700, and then, the clothing continues to be conveyed forward for the second length folding until the rear end of the clothing. The clothes pass completely forward through the second clothing clamping mechanism 800 corresponding to the position on the upper surface of the second conveying mechanism 700, that is, the rear end of the clothes falls on the upper surface of the second conveying mechanism 700. At this time, the front conveying device 300, the rear conveying device 200 and the second conveying mechanism 700 stop running, and the second clothing clamping mechanism 800 releases the clothes and stays above the front conveying device 300 and the second conveying mechanism 700. The rear end of the clothes falls on the surface of the clothes located on the upper surface of the second conveying mechanism 700, and the above-mentioned ends of the clothes and the rear end of the clothes are stacked correspondingly, and the clothes complete the second length folding.

[0109] Example 3

[0110] like Figure 7 As shown, the main difference between this embodiment and Embodiment 2 is that the second conveying mechanism 700 is located in front of the first conveying mechanism 100 as a whole and is arranged horizontally, and the rear edge of the second conveying mechanism 700 is gap-connected with the front edge of the first conveying mechanism 100 .

[0111] like Figure 7 , Figure 8 As shown, the second clothing clamping mechanism 800 of this embodiment is arranged corresponding to the gap between the first conveying mechanism 100 and the second conveying mechanism 700. In specific implementation, the second upper clamping portion 811 of the second clothing clamping mechanism 800 is located above the first conveying mechanism 100 and the second conveying mechanism 700, and the second lower clamping portion 812 is adjusted up and down between the lower part of the gap and the second upper clamping portion 811. Similarly, the first upper clamping portion 411 of the first clothing clamping mechanism 400 is located above the rear conveying device 200 and the front conveying device 300, and the first lower clamping portion 412 is adjusted up and down between the lower part of the gap and the second upper clamping portion 811.

[0112] During operation, the clothes can be efficiently transported back and forth between the first conveying mechanism 100 and the second conveying mechanism 700. In the non-clamping state, the corresponding lower clamping part of the first clothes clamping mechanism 400 or the second clothes clamping mechanism 800 is located at the bottom of the gap between the two adjacent conveying mechanisms, which can avoid blocking the clothes transported back and forth. In the clamping state, the corresponding lower clamping part of the first clothes clamping mechanism 400 or the second clothes clamping mechanism 800 rises to bring up the clothes and finally clamps the clothes on the corresponding upper clamping part. At this time, a length folding space is formed between the lower part of the clamping mechanism clamping the clothes and the corresponding conveying mechanism. In this embodiment, the clothes that have completed the length folding are finally transported and stopped above the second conveying mechanism 700. The clothes can be sent out of the length folding system 11 by continuing to transport the clothes forward through the second conveying mechanism 700. At this time, the device corresponding to the storage process can be set in front of the second conveying mechanism 700 to receive the clothes that fall from the front edge of the second conveying mechanism 700.

[0113] During specific operation, the front conveying device 300, the rear conveying device 200, and the second conveying mechanism 700 are connected and coordinated front and back to continuously convey the clothes forward. After the clothes pass through the first clothes clamping mechanism 400, they continue to be conveyed forward. When the rear end of the clothes just passes through the position of the first clothes clamping mechanism 400 corresponding to the upper surface of the front conveying device 300 and the rear conveying device 200, the front conveying device 300 and the rear conveying device 200 both stop running, and the first clothes clamping mechanism 400 clamps the clothes and lifts them to the top between the front conveying device 300 and the rear conveying device 200. At this time, the first clothes clamping mechanism 400 brings up the clothes and the rear clothes clamping mechanism below A first length folding space is formed on the upper surface of the conveying device 200; then, the front conveying device 300 and the rear conveying device 200 are operated to jointly convey the clothes backward and pass through the first length folding space below the first clothes clamping mechanism 400 to perform a length folding, until the front end of the clothes just passes the front edge of the front conveying device 300. At this time, the first and second conveying crawler devices stop running, the first clothes clamping mechanism 400 releases the clothes and stays above the first conveying mechanism, and the rear end of the clothes falls on the clothes surface located on the upper surfaces of the rear conveying device 200 and the front conveying device 300, and the clothes complete the first length folding.

[0114] Afterwards, the second clothing clamping mechanism 800 clamps the front end of the clothing just passing through the front edge of the front conveying device 300 and lifts it, at this time, a second length folding space is formed between the second clothing clamping mechanism 800 and the upper surface of the second conveying mechanism 700 below; then, the rear conveying device 200, the front conveying device 300 and the second conveying mechanism 700 cooperate to continue to convey the clothing that has been folded in length for the first time forward, the clothing passes through the second length folding space and falls on the second conveying mechanism 700, thereafter, the clothing continues to be conveyed forward for the second length folding until the rear end of the clothing completely passes forward through the position of the second clothing clamping mechanism 800 corresponding to the upper surface of the second conveying mechanism 700, at this time, the front conveying device 300, the rear conveying device 200 and the second conveying mechanism 700 stop running, the second clothing clamping mechanism 800 releases the clothing and stays above between the front conveying device 300 and the second conveying mechanism 700, the rear end of the clothing falls on the clothing surface located on the upper surface of the second conveying mechanism 700, the above-mentioned ends of the clothing and the rear ends of the clothing are stacked correspondingly, and the clothing completes the second length folding.
