Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliance manufacturing, and more specifically, to a conveying 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 folding the clothes longitudinally at least once, and 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 conveying 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 of all being in a stacking form, and also includes a first and a second holding conveyor, each holding conveyor includes at least three holding rollers.

[0003] It can be seen that the existing conveying mechanism of the folding machine either has many levels, which takes up a lot of space in the vertical direction, or needs to match and set up many mechanical parts, resulting in a complex overall structure, which affects the miniaturization design of the whole machine and is inconvenient to promote to household use. In addition, in the prior art, there is a lack of control means when the clothes are in contact with the conveying mechanism during the continuous conveying process, which may cause the clothes conveying process to be unstable and may affect the flatness of the clothes. 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 conveying system of a clothes folding machine, which is used to solve the problems of complex structure and unstable conveying.

[0005] The technical solution adopted by the utility model is to provide a conveying system of a clothes folding machine for conveying clothes, comprising a frame and a first conveying mechanism, a second conveying mechanism and a flipping and holding mechanism arranged on the frame; the first conveying mechanism and the second conveying mechanism are arranged up and down, the flipping and holding mechanism is arranged behind the first conveying mechanism and above the second conveying mechanism, and the flipping and holding mechanism is configured to transfer the clothes conveyed by the first conveying mechanism to the second conveying mechanism; wherein, a pressing mechanism installed on the frame is respectively arranged above the first conveying mechanism and the second conveying mechanism, and the pressing mechanisms are configured to press down the clothes.

[0006] In this solution, the clothes that have completed the previous process are first sent to the upper surface of the first conveying mechanism. The first conveying mechanism conveys the clothes from front to back and turns the clothes over through the connection of the flipping and holding mechanism and then transfers them to the upper surface of the second conveying mechanism. Then, the second conveying mechanism continues to convey the clothes until entering the next process. In this solution, by configuring a downward pressure mechanism above the first conveying mechanism and the second conveying mechanism, the clothes are subjected to continuous downward pressure during the conveying process. On the one hand, it can compress the thickness of the clothes to improve the flatness, and on the other hand, it can increase the friction between the clothes and the surface of the conveying mechanism to make the conveying process stable and efficient. In addition, this solution only uses two layers of conveying mechanisms, and cooperates with the downward pressure mechanism to achieve continuous and stable conveying of clothes, which reduces the complexity of the mechanical structure of the conveying system and reduces the space it occupies, which is conducive to the miniaturization of the whole clothes folding machine.

[0007] Furthermore, the flipping and holding mechanism is a second crawler device having a flexible crawler, and the second crawler device is closely attached to the rear edge of the first conveying mechanism.

[0008] In this solution, there is elastic contact between the rear edge of the first conveying mechanism and the flipping and holding mechanism. After the first conveying mechanism conveys the clothes from front to back to the flipping and holding mechanism, the clothes are "squeezed" on the front surface of the flipping and holding mechanism by the rear edge of the first conveying mechanism. The front surface of the flipping and holding mechanism is configured to convey the clothes from top to bottom, thereby transferring the clothes to the upper surface of the second conveying mechanism below.

[0009] Optionally, the first conveying mechanism is a first crawler device.

[0010] Optionally, the crawler track of the first crawler device is a flexible crawler track.

[0011] In this solution, the pressing mechanism is elastically in contact with the flexible crawler. When the clothes are pressed down by the pressing mechanism on the surface of the first crawler device, on the one hand, the pressure applied to the clothes creates a greater friction between the clothes and the flexible crawler to achieve smooth transportation. On the other hand, excessive downward pressure can be avoided to clamp the clothes between the pressing mechanism and the surface of the first crawler device.

[0012] Optionally, the second crawler device is arranged obliquely relative to the upper surface of the first conveying mechanism and forms an obtuse inclination angle with the upper surface of the first conveying mechanism.

[0013] This solution ensures that when the second crawler device is conveying clothes, the clothes are supported upward, which, combined with the "squeezing" effect of the rear edge of the first conveying mechanism, can make the clothing conveying process more reliable.

[0014] Optionally, the first track device comprises a track component and a first drive assembly, the track component is provided with at least a pair of traction rollers located on both sides of the track component, and the first drive assembly drives at least one of the traction rollers.

[0015] Optionally, the first driving assembly includes a first motor and a first pulley assembly, the first pulley assembly is provided with a first synchronous belt and two first gears, the two first gears are respectively connected to the first motor and the traction roller and are meshed and driven by the first synchronous belt.

[0016] Optionally, a lower edge of the flipping and holding mechanism is spaced apart from an upper surface of the second conveying mechanism.

[0017] When certain processes are performed, the clothes need to be transported backwards by the second transport mechanism. This solution can prevent the clothes transported backwards from being blocked by the lower edge of the flipping and holding mechanism.

[0018] Furthermore, the pressing mechanism comprises a first pressing roller device, and the first pressing roller device can be adjusted up and down relative to the upper surface of the first conveying mechanism.

[0019] This solution can adjust the appropriate downward pressure according to the thickness, material and other properties of the clothes to ensure smooth transportation of the clothes.

[0020] Optionally, the first pressing roller device includes a first support member, a roller bracket and at least one roller, the first support member is fixed to the frame and is located above the roller, the rear end of the roller bracket is movably arranged on the first support member so that the front end of the roller bracket can swing up and down, and the front end of the roller bracket is sleeved with the roller.

[0021] In this solution, the clothes are sent to the surface of the first conveying mechanism below the first pressing roller device. The first pressing roller device is movable and controlled at the rear end of the roller bracket of the first support member, so that the front end of the roller bracket swings downward, thereby driving the roller to press the clothes against the upper surface of the conveying mechanism. When the first conveying mechanism conveys the clothes backward, the roller is driven by the conveying mechanism to rotate and continuously press the clothes passing below it. The use of the roller structure can not only continuously press the clothes by the rotation of the roller itself, but also reduce the wear of the roller structure on the surface of the clothes.

[0022] Furthermore, the second conveying mechanism includes two conveying devices connected with a front and rear gap and a second driving assembly, and the pressing mechanism is arranged above at least one of the conveying devices.

[0023] This solution can avoid mutual interference between the two conveying devices during operation by setting a gap, and can also make the clothes more smoothly transported frontward and rearward.

[0024] Furthermore, the two conveying devices are respectively a third crawler device and a fourth crawler device, and the pressing mechanism also includes a second pressure roller device and a third pressure roller device, wherein the second pressure roller device can be adjusted up and down relative to the surface of the third crawler device, and the third pressure roller device can be adjusted up and down relative to the surface of the fourth crawler device.

[0027] In this solution, a second motor can synchronously drive the front traction roller of the third crawler device and the rear traction roller of the fourth crawler device, so that the front traction roller of the third crawler device serves as its active roller to pull the third crawler device, and the rear traction roller of the fourth crawler device serves as its active roller to pull the fourth crawler device, and the third crawler device and the fourth crawler device maintain the same direction during the forward and backward conveying process.

[0028] Optionally, the second pressing roller device and the third pressing roller device both include a roller and a pair of support seats for supporting the corresponding rollers, the support seats are respectively arranged on the frames on both sides, and oblong holes are opened on the support seats.

[0029] In this solution, the rollers of the second pressing roller device and the third pressing roller device can be adjusted up and down through the oblong holes 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.

[0030] Optionally, the support seat is a bearing support seat.

[0031] Furthermore, a third conveying mechanism is provided, at least a part of which is located in front of the second conveying mechanism, and a third pressing mechanism installed on the frame is provided above the third conveying mechanism, and the third pressing mechanism can be adjusted up and down relative to the upper surface of the third conveying mechanism.

[0032] Optionally, the third conveying mechanism is located in front of the second conveying mechanism, and a rear edge of the third conveying mechanism is gap-connected with a front edge of the second conveying mechanism.

[0033] In this solution, the clothes can be efficiently transported back and forth between the second conveying mechanism and the third conveying mechanism, and the third conveying mechanism continues to transport the clothes forward to send the clothes out of the conveying system.

[0034] Optionally, the third conveying mechanism is arranged to be gradually inclined upward from below the second conveying mechanism to the front of the second conveying mechanism.

[0035] In this solution, when conveying clothes forward, the clothes conveyed by the second conveying mechanism fall from the rear edge of the second conveying mechanism to the front edge of the third conveying mechanism, and then the third conveying mechanism drives the clothes to continue to be conveyed forward; in addition, when the clothes are located as a whole on the upper surface of the third conveying mechanism, the third mechanism can send the clothes out of the conveying system by conveying the clothes backward.

[0036] Optionally, the third conveying mechanism is a fifth crawler device.

[0037] Optionally, the crawler track of the fifth crawler device is a flexible crawler track.

[0038] Optionally, the fifth crawler device includes at least a pair of traction rollers arranged at the front and rear ends and a crawler track pulled by the traction rollers.

[0039] Optionally, it also includes a third pulley assembly, which is provided with a third synchronous belt and two third gears. The two third gears are respectively arranged on the front traction roller of the fourth crawler device and the rear traction roller of the fifth crawler device and are both driven by the third synchronous belt.

[0040] Optionally, the third pressing mechanism is a fourth pressing roller device, which includes a roller and a pair of support seats for supporting the corresponding rollers, the support seats are respectively arranged on the frames on both sides, and the support seats are provided with oblong holes.

[0041] In this solution, the roller of the fourth pressing roller device can be 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-to-back conveying of clothes.

[0042] Optionally, the support seat is a bearing support seat.

[0043] Furthermore, a first clothing clamping mechanism is provided, which is arranged between the two conveying devices and can be raised and lowered relative to the upper surface of the conveying device. The second conveying mechanism conveys the clothing backwards and cooperates with the first clothing clamping mechanism to fold the clothing once in length.

[0044] In this solution, the two conveying devices of the second conveying mechanism are connected and cooperated to continuously convey the clothes forward. When the first preset position of the rear part of the clothes passes through the first clothes clamping mechanism, the second conveying mechanism stops running, and the first clothes clamping mechanism clamps the clothes and lifts them; then, the second conveying mechanism is operated to convey the clothes backward and pass under the first clothes clamping mechanism to perform a length folding, until the clothes are conveyed backward to the second preset position at the rear, the second conveying mechanism stops running, the first clothes clamping mechanism releases the clothes and stays above the second conveying mechanism, at this time, the clothes complete a length folding. During the above-mentioned length folding process, this solution also continuously presses down the clothes through the pressing mechanism to offset the lifting effect of the first clothes clamping mechanism on the clothes, so that sufficient friction is generated between the clothes and the upper surface of the conveying mechanism to ensure smooth conveying of the clothes.

[0045] Furthermore, a second clothing clamping mechanism is provided, which is located between the second conveying mechanism and the third conveying mechanism and can be raised and lowered relative to the upper surface of the second conveying mechanism. The second conveying mechanism and the third conveying mechanism convey the clothing forward and cooperate with the second clothing clamping mechanism to fold the clothing once in length.

[0046] In the present scheme, during the process of the second conveying mechanism and the third conveying mechanism cooperating to convey the clothes backward, when the first preset position of the front part of the clothes passes through the second clothes clamping mechanism, the second conveying mechanism and the third conveying mechanism stop running, the second clothes clamping mechanism clamps the clothes and lifts them, and a folding space of a second length is formed between the second clothes clamping mechanism, the lifted clothes and the conveying mechanism below; then, the second conveying mechanism and the third conveying mechanism are restarted to convey the clothes forward, and the clothes continue to be conveyed forward through the length folding space below the second clothes clamping mechanism to perform a length folding, until the clothes are conveyed forward to the second preset position in front, the second conveying mechanism and the third conveying mechanism stop running, the second clothes clamping mechanism releases the clothes and stays on the upper side of the second conveying mechanism, and at this time, the clothes complete a length folding.

[0047] Optionally, both the first clothing clamping mechanism and the second clothing clamping mechanism have an extended length, and both ends of the first clothing clamping mechanism and the second clothing clamping mechanism are respectively arranged on two side frames.

[0048] The first clothing clamping mechanism and the second clothing clamping mechanism of the present invention have a larger clamping area when clamping clothing, thereby improving the clamping stability.

[0049] Optionally, the first clothing clamping mechanism and the second clothing clamping mechanism each include an upper clamping portion and a lower clamping portion that are matched with each other in upper and lower directions.

[0050] Optionally, the lower clamping portion can be raised and lowered relative to the upper clamping portion.

[0051] Optionally, the lowest position of the lower clamping portion for downward adjustment is located below the upper surface of the second conveying mechanism.

[0052] When the length folding is not performed, the clothes need to continue to pass through the upper surface of the second conveying mechanism. The setting method of the lower clamping part of this scheme can avoid blocking the clothes and ensure continuous and smooth conveyance of the clothes.

[0053] Optionally, the upper clamping parts are each provided with an inverted "V"-shaped groove, and the lower clamping part is a rotating part.

[0054] 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.

[0055] Compared with the prior art, the beneficial effects of the utility model are as follows: by disposing a downward pressing mechanism above the mutually connected conveying mechanisms, the clothes always maintain sufficient friction with the surface of the conveying mechanism during the conveying process, thereby improving the stability and efficiency of the conveying process, and having a flattening effect on the thickness of the clothes, which is helpful for the subsequent folding process; by providing the flipping and holding mechanism with a flexible crawler component, elastically abutting against the rear edge of the first conveying mechanism, the clothes transferred by the rear edge of the first conveying mechanism are elastically squeezed on the surface of the flipping and holding mechanism, and in conjunction with the obtuse angle tilting setting of the flipping and holding mechanism, the clothes are smoothly conveyed between the first conveying mechanism and the second conveying mechanism; in addition, one length folding is completed by the third conveying crawler and the third conveying crawler cooperates with the first clothes clamping mechanism, and another length folding is completed by the second conveying mechanism, the third conveying mechanism and the second clothes clamping mechanism cooperate, and the clothes that have completed the first length folding can also be folded by the other length folding, thereby performing a second length folding on the same piece of clothes.

DETAILED DESCRIPTION

[0064] 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.

[0065] Example 1

[0066] like Figure 1-2As shown, the present embodiment provides a conveying system 11 of a clothes folding machine 1, which is used to convey clothes, and includes a frame 12 and a first conveying mechanism 100, a second conveying mechanism 200 and a flipping and holding mechanism 300 arranged on the frame 12; the first conveying mechanism 100 and the second conveying mechanism 200 are arranged up and down, the flipping and holding mechanism 300 is arranged behind the first conveying mechanism 100 and above the second conveying mechanism 200, and the flipping and holding mechanism 300 is configured to transfer the clothes conveyed by the first conveying mechanism 100 to the second conveying mechanism 200; wherein, the first conveying mechanism 100 and the second conveying mechanism 200 are respectively matched with a first pressing mechanism 410 and a second pressing mechanism installed on the frame 12, and the first pressing mechanism 410 and the second pressing mechanism are both configured to press down the clothes.

[0067] During operation, the clothes that have completed the previous process are first sent to the upper surface of the first conveying mechanism 100. The first conveying mechanism 100 conveys the clothes from front to back and turns the clothes over and transfers them to the upper surface of the second conveying mechanism 200 through the connection of the flipping and holding mechanism 300. Then, the second conveying mechanism 200 continues to convey the clothes until entering the next process. Since the pressing mechanism is respectively arranged above the first conveying mechanism 100 and the second conveying mechanism 200, the clothes are subjected to continuous pressing action during the conveying process. On the one hand, it can compress the thickness of the clothes to improve the flatness, and on the other hand, it can also increase the friction between the clothes and the surface of the conveying mechanism to make the conveying process stable and efficient. In addition, since the continuous and stable conveying of clothes can be achieved by only two layers of conveying mechanisms and the corresponding pressing mechanisms, the mechanical structure complexity of the conveying system 11 is reduced and the space it occupies is reduced, which is conducive to the miniaturization of the whole machine of the clothes folding machine 1.

[0068] like Figure 2 , Figure 4 As shown, the flipping and holding mechanism 300 is a second crawler device with a flexible crawler, and the second crawler device is close to the rear edge of the first conveying mechanism 100. In specific implementation, the second crawler device at least includes a second crawler 310 and a pair of second traction rollers 320 arranged at both ends of the second crawler 310, and the two ends of the second traction roller 320 are supported on the frames 12 on both sides.

[0069] During operation, the rear edge of the first conveying mechanism 100 is in elastic contact with the flipping and holding mechanism 300. After the first conveying mechanism 100 conveys the clothes from front to back to the flipping and holding mechanism 300, the clothes are "pressed" on the front surface of the flipping and holding mechanism 300 by the rear edge of the first conveying mechanism 100. The front surface of the flipping and holding mechanism 300 is configured to convey the clothes from top to bottom through the friction of the first conveying mechanism, thereby transferring the clothes to the upper surface of the second conveying mechanism 200 below. In order to better connect with the first conveying mechanism 100, the upper edge of the second crawler device is located above the rear edge of the first conveying mechanism 100.

[0070] The first conveying mechanism 100 is a first crawler belt 110 device. In a specific implementation, in order to better cooperate with the pressing mechanism, the crawler belt of the first crawler belt 110 device is a first flexible crawler belt.

[0071] During implementation, the pressing mechanism and the flexible crawler are elastically abutted against each other. When the clothes are pressed down on the surface of the first crawler 110 device by the pressing mechanism, on the one hand, the pressure applied to the clothes creates a greater friction between the clothes and the flexible crawler to achieve smooth transportation. On the other hand, excessive downward pressure can be avoided to cause the clothes to be stuck between the pressing mechanism and the surface of the first crawler 110 device.

[0072] like Figure 3-4 As shown, the second crawler device is inclined relative to the upper surface of the first conveying mechanism 100 and forms an obtuse inclination angle with the upper surface of the first conveying mechanism 100. During the process of the second crawler device conveying clothes, the clothes can be supported by an upward force, which, combined with the "squeezing" effect of the rear edge of the first conveying mechanism 100, can make the clothing conveying process more reliable.

[0073] Among them, the first crawler 110 device includes a crawler component and a first drive assembly 130. The crawler component is provided with at least a pair of first traction rollers 120 located on both sides of the crawler component and a first crawler 110 pulled by the first traction rollers 120. The first drive assembly 130 is used to drive at least one of the first traction rollers 120.

[0074] In a preferred embodiment, if Figure 2-4 As shown, the first driving assembly 130 includes a first motor 131 and a first pulley assembly 132. The first pulley assembly 132 is provided with a first synchronous belt 132a and two first gears 132b. The two first gears 132b are respectively connected to the first motor 131 and the first traction roller 120, and are meshed and transmitted through the first synchronous belt 141.

[0075] like Figure 3 As shown, the lower edge of the flipping and holding mechanism 300 is spaced apart from the upper surface of the second conveying mechanism 200. When the clothes are conveyed backwards by the second conveying mechanism 200, the clothes can smoothly pass through the gap between the flipping and holding mechanism 300 and the second conveying mechanism 200, avoiding the clothes being blocked by the lower edge of the flipping and holding mechanism 300.

[0076] like Figure 2As shown, the first pressing mechanism 410 is specifically configured as a first pressing roller device, and the first pressing roller device can be adjusted up and down relative to the upper surface of the first conveying mechanism 100. During implementation, the first pressing roller device can be adjusted to perform a suitable downward pressing amplitude according to the thickness, material and other properties of the clothes to ensure smooth conveying of the clothes. In addition, in order to facilitate coordination with corresponding devices of other processes, in a preferred embodiment, a pair of first pressing roller devices are provided, and are arranged at intervals in the width direction of the first conveying mechanism 100. The space between the pair of first pressing roller devices is convenient for the corresponding devices of other processes to pass through when moving forward and backward, which can make the overall structure of the folding machine compact and conducive to miniaturized layout.

[0077] Among them, Figure 2 , Figure 4 As shown, the first pressing roller device includes a first support member 411, a roller bracket 412 and at least one first roller 413. The first support member 411 is fixed to the frame 12 and is located above the first roller 413. The rear end of the roller bracket 412 is movably arranged on the first support member 411 so that the front end of the roller bracket 412 can swing up and down, and the front end of the roller bracket 412 is sleeved with the first roller 413.

[0078] When working, the clothes are sent to the first conveying mechanism 100 below the first pressing roller device. The first pressing roller device is controlled by the rear end of the roller bracket 412 of the first support member 411, so that the front end of the roller bracket 412 swings downward, thereby driving the first roller 413 to press the clothes against the upper surface of the first conveying mechanism 100. When the first conveying mechanism 100 conveys the clothes backward, the first roller 413 is driven by the first conveying mechanism 100 to rotate and continuously press the clothes passing below it. The use of the roller structure can not only continuously press the clothes by the rotation of the roller itself, but also reduce the wear of the roller structure on the surface of the clothes.

[0079] like Figure 3 , Figure 5 As shown, the second conveying mechanism 200 includes two conveying devices connected with a gap in the front and back and a second driving assembly 230, and a pressing mechanism is provided on at least one of the conveying devices. The gap setting can not only avoid the two conveying devices from interfering with each other during operation, but also make the clothes more smoothly transported in the front and back.

[0080] Among them, the two conveying devices are the third crawler device 210 and the fourth crawler device 220, and the second pressing mechanism includes a second pressure roller device 420 and a third pressure roller device 430, wherein the second pressure roller device 420 can be adjusted up and down relative to the surface of the third crawler device 210, and the third pressure roller device 430 can be adjusted up and down relative to the surface of the fourth crawler device 220.

[0081] When implementing it, Figure 5As shown, the third crawler device 210 includes at least two third traction rollers 212 arranged at the front and rear ends and a third crawler 211 pulled by the third traction rollers 212, and the two ends of the third traction rollers 212 are respectively supported on the frames 12 on both sides.

[0082] In addition, the fourth crawler device 220 includes at least two fourth traction rollers 222 arranged at the front and rear ends and a fourth crawler 221 pulled by the fourth traction rollers 222. The two ends of the fourth traction rollers 222 are respectively supported on the frames 12 on both sides.

[0083] In order to cooperate with the downward pressure of the downward pressure mechanism to smoothly transport the clothes forward and backward, the third crawler belt 211 is a third flexible crawler belt, and the fourth crawler belt 221 is a fourth flexible crawler belt.

[0084] Among them, Figure 3 , Figure 5 As shown, the second drive assembly 230 includes a second motor 231 and a second pulley assembly 232. The second pulley assembly 232 is provided with a second synchronous belt 232a and three second gears 232b. The three second gears 232b are respectively provided on the second motor 231, the front third traction roller 212 of the third crawler device 210, and the rear fourth traction roller 222 of the fourth crawler device 220, and are all driven by the second synchronous belt 232a.

[0085] When working, a second motor 231 can synchronously drive the front third traction roller 212 of the third crawler device 210 and the rear fourth traction roller 222 of the fourth crawler device 220, so that the front third traction roller 212 of the third crawler device 210 serves as its active roller to pull the third crawler device 210, and the rear fourth traction roller 222 of the fourth crawler device 220 serves as its active roller to pull the fourth crawler device 220, and the third crawler device 210 and the fourth crawler device 220 maintain the same direction during the forward and backward transportation.

[0086] like Figure 2 , Figure 5 As shown, the second roller device 420 includes a second roller 421 and a pair of second support seats 422 for supporting the second roller 421; the third roller device 430 includes a third roller 431 and a pair of third support seats 432 for supporting the third roller 431. The second support seat 422 and the third support seat 432 are respectively arranged on the frame 12 on both sides, and oblong holes are opened on the support seats. When working, the rollers of the second roller device 420 and the third roller device 430 can be adjusted up and down through the oblong holes on the support seats, so that the appropriate downward pressure amplitude can be adjusted for different clothes, and the clothes can be efficiently transported forward and backward. In addition, in order to better support the rollers, the support seats are all bearing support seats.

[0087] like Figure 2 , Figure 3 , Figure 5 As shown, a third conveying mechanism 500 is also provided, at least a portion of which is located in front of the second conveying mechanism 200, and a fourth pressing roller device 440 is installed on the frame above the third conveying mechanism 500, and the fourth pressing roller device 440 can be adjusted up and down relative to the upper surface of the third conveying mechanism 500.

[0088] In some embodiments, the third conveying mechanism 500 is located in front of the second conveying mechanism 200, and the rear edge of the third conveying mechanism 500 is gap-connected with the front edge of the second conveying mechanism 200. During operation, the clothes can be continuously transported back and forth between the second conveying mechanism 200 and the third conveying mechanism 500, and the clothes are finally sent out of the conveying system 11 from the front edge of the third conveying mechanism 500. At this time, a storage device can be provided in front of the third conveying mechanism 500 to store the clothes.

[0089] like Figure 5 As shown, in a preferred embodiment, the third conveying mechanism 500 is arranged to be inclined upward from the bottom of the second conveying mechanism 200 to the front of the second conveying mechanism 200. In specific implementation, in order to better receive the clothes sent from the front edge of the second conveying mechanism 200 and continue to reliably convey the clothes forward, it is necessary to adjust the inclination angle formed between the third conveying mechanism 500 and the lower surface of the second conveying mechanism 200.

[0090] During operation, when conveying clothes forward, the clothes conveyed by the second conveying mechanism 200 fall from the rear edge of the second conveying mechanism 200 to the front edge of the third conveying mechanism 500, and then the third conveying mechanism 500 drives the clothes to continue to be conveyed forward; in addition, when the clothes are located as a whole on the upper surface of the third conveying mechanism 500, the third mechanism conveys the clothes backward and finally sends the clothes out of the conveying system 11 from the rear edge of the third conveying mechanism 500. A storage device can be provided under the second conveying mechanism 200 to store the clothes. At this time, the storage device can be located in the space covered by the second conveying mechanism 200, which helps to miniaturize the overall setting of the clothes folding machine 1.

[0091] In a specific implementation, the third conveying mechanism 500 is a fifth crawler 510 device, wherein the fifth crawler 510 device at least includes two fifth traction rollers 520 arranged at the front and rear ends and the fifth crawler 510 pulled by the fifth traction rollers 520. In order to ensure that the clothes can be smoothly conveyed on the conveying mechanism when the pressing mechanism is pressed down, the crawler of the fifth crawler 510 device is set to be a fifth flexible crawler.

[0092] like Figure 3 , Figure 5As shown, it also includes a third pulley assembly 530, which is provided with a third synchronous belt 531 and two third gears 532. The two third gears 532 are respectively arranged on the front fourth traction roller 222 of the fourth crawler device 220 and the rear fifth traction roller 520 of the fifth crawler device 510, and are both meshed and driven by the third synchronous belt 531.

[0093] As shown in the figure, the fourth pressing roller device 440 includes a fourth roller 441 and a pair of fourth support seats 442 for supporting and setting the fourth roller 441. The support seats are respectively arranged on the frame 12 on both sides, and oblong holes are opened on the support seats. In specific implementation, in order to improve the support stability, the fourth support seat 442 is set as a bearing support seat.

[0094] When working, the fourth roller 441 of the fourth pressure roller device 440 can be adjusted up and down through the oblong hole on the support seat, so that the appropriate downward pressure amplitude can be adjusted according to different clothes to achieve efficient front and back conveying of clothes.

[0095] like Figure 2 , Figure 6 As shown, a first clothing clamping mechanism 600 is also provided. The first clothing clamping mechanism 600 is provided between the third track device 210 and the fourth track device 220 and can be raised and lowered. The second conveying mechanism 200 conveys the clothing backwards and cooperates with the first clothing clamping mechanism 600 to fold the clothing once in length.

[0096] During implementation, the third crawler device 210 and the fourth crawler device 220 are connected and cooperated to continuously convey the clothes forward. When the first preset position at the rear of the clothes passes the first clothes clamping mechanism 600, the third crawler device 210 and the fourth crawler device 220 stop running, and the first clothes clamping mechanism 600 clamps the clothes and lifts them, and a folding space is formed between the first clothes clamping mechanism 600 and the upper surface of the second conveying mechanism below; then, the third crawler device 210 and the fourth crawler device 220 are operated to convey the clothes backward and pass through the folding space below the first clothes clamping mechanism 600 to perform a length folding, until the clothes are conveyed backward to the second preset position at the rear, the third crawler device 210 and the fourth crawler device 220 stop running, the first clothes clamping mechanism 600 releases the clothes and stays above the second conveying mechanism 200, at which time, the clothes complete a length folding. During the above-mentioned one-length folding process, the present solution also continuously presses down the clothes through the pressing mechanism to offset the lifting effect of the first clothes clamping mechanism 600 on the clothes, thereby generating sufficient friction between the clothes and the track device to ensure smooth transportation of the clothes.

[0097] In a specific implementation, the first preset position at the rear can be the rear end of the clothing. At this time, the first clothing clamping mechanism clamps the rear end of the clothing, which helps to fold the clothing to a sufficient length. In addition, the second preset position at the rear can be the position where the rear of the clothing is located when the front end of the clothing is conveyed backwards and just passes the front edge of the second conveying mechanism 200.

[0098] like Figure 2 , Figure 6 As shown, a second clothing clamping mechanism 700 is also provided. The second clothing clamping mechanism 700 is located between the second conveying mechanism 200 and the third conveying mechanism 500 and can be raised and lowered relative to the upper surface of the second conveying mechanism 200. The second conveying mechanism 200 and the third conveying mechanism 500 convey the clothing forward and cooperate with the second clothing clamping mechanism 700 to fold the clothing once in length.

[0099] During specific implementation, in order to avoid blocking the path of clothing in the clamping and releasing states, the first clothing clamping mechanism 600 and the second clothing clamping mechanism 700 both need to undergo certain structural designs. For example, the clothing clamping mechanism can be disposed as a whole on the upper side of the second conveying mechanism. When clothing needs to be clamped, the corresponding clothing clamping mechanism descends to the surface of the clothing to clamp the clothing.

[0100] A more preferred method is as follows Figure 2 , Figure 6 , Figure 7 As shown, the first clothing clamping mechanism 600 and the second clothing clamping mechanism 700 both include an upper clamping portion 610 and a lower clamping portion 620 that are matched with each other, wherein the lowest position of the lower clamping portion 620 for downward adjustment is located below the upper surface of the second conveying mechanism 200, while the upper clamping portion 610 is maintained above the second conveying mechanism. When the length folding is not performed, the clothing continues to pass through the upper surface of the second conveying mechanism 200, and this embodiment can avoid obstruction to the clothing and ensure that the clothing is continuously and smoothly conveyed; when the clothing needs to be clamped, the lower clamping portion 620 lifts the clothing upward and engages with the upper clamping portion 610 to clamp the clothing. At this time, a length folding space is formed between the corresponding clothing clamping mechanism and the surface of the second conveying mechanism or the third conveying mechanism, and the clothing can be folded in length by continuously conveying the clothing.

[0101] During implementation, the first clothing clamping mechanism 600 and the second clothing clamping mechanism 700 are both provided with a clamping driver 630, and the clamping driver 630 is used to drive the lower clamping part 620 to rise and fall to abut against or move away from the upper clamping part 610, thereby clamping or releasing the clothing.

[0102] During operation, the second conveying mechanism 200 and the third conveying mechanism 500 cooperate to convey the clothes backwards. When the first preset position of the front part of the clothes passes through the second clothes clamping mechanism 700, the second conveying mechanism 200 and the third conveying mechanism 500 stop running, the second clothes clamping mechanism 700 clamps the clothes and lifts them, and a folding space is formed between the second clothes clamping mechanism 700 and the conveying mechanism surface below; then, the second conveying mechanism 200 and the third conveying mechanism 500 are restarted to convey the clothes forward, and the clothes continue to be conveyed forward through the folding space below the second clothes clamping mechanism 700 to perform a length folding, until the clothes are conveyed forward to the second preset position in front, the second conveying mechanism 200 and the third conveying mechanism 500 stop running, the second clothes clamping mechanism 700 releases the clothes and stays on the upper side of the second conveying mechanism 200, and the clothes complete a length folding.

[0103] In a specific implementation, the first preset position in the front may be the front end of the clothing. At this time, the second clothing clamping mechanism 700 clamps the front end of the clothing, which helps to fold the clothing to a sufficient length. In addition, the second preset position in the front may be that the entire clothing is conveyed to the front of the second conveying mechanism 200, and specifically, the entire clothing is supported on the third conveying mechanism 500 to form a sufficient length fold.

[0104] Among them, Figure 2 , Figure 6 As shown, the first clothing clamping mechanism 600 and the second clothing clamping mechanism 700 both have an extended length, and both ends of the first clothing clamping mechanism 600 and the second clothing clamping mechanism 700 are respectively arranged on the two side frames 12. Since the first clothing clamping mechanism 600 and the second clothing clamping mechanism 700 have a larger clamping area when clamping clothing, the clamping stability can be improved.

[0105] In order to optimize the clamping effect, in a specific implementation, the upper clamping part 610 is provided with an inverted "V" shaped groove 611, and the lower clamping part 620 is a rotating part. When the first clothing clamping mechanism 600 or the second clothing clamping mechanism 700 clamps the clothing, the "V" shaped groove 611 cooperates with the rotating part to form a larger clamping area for the clothing and obtain a reliable clamping force. In addition, when the clamped part of the clothing needs to change its direction, the clothing can be rotated around the rotating part as the axis to achieve this.

[0106] In specific application, the clothes are sent to the top of the first conveying mechanism 100, and the first conveying mechanism 100 conveys the clothes backward. When the clothes pass under the first pressing roller device, the first roller 413 of the first pressing roller device presses down on the clothes, and the first conveying mechanism 100 continues to convey the clothes. The friction between the surface of the clothes and the roller of the first pressing roller device continuously drives the first roller 413 to rotate, so that the first roller 413 continuously presses down the clothes conveyed backward. When the clothes are conveyed backward out of the rear edge of the first conveying mechanism 100, the clothes are conveyed by the joint friction between the rear edge of the first conveying mechanism 100 and the front surface of the flip holding mechanism 300. At this time, the rear edge of the first conveying mechanism 100 can act as a "squeezing" function, and the clothes are continuously pressed against the front surface of the flip holding mechanism 300. The flip holding mechanism 300 is tilted to provide support for the clothes, and finally the clothes are conveyed to the second conveying mechanism 200.

[0107] After that, the third crawler device 210 and the fourth crawler device 220 are connected and cooperated to continuously transport the clothes forward. When the first preset position of the rear part of the clothes passes through the first clothes clamping mechanism 600, which can be the rear end of the clothes, at this time, the third crawler device 210 and the fourth crawler device 220 stop running, and the first clothes clamping mechanism 600 clamps the clothes and lifts them, and the first clothes clamping mechanism 600 and the upper surface of the crawler device below form a first length folding space; then, the third crawler device 210 and the fourth crawler device 220 are operated to transport the clothes backward. The clothes are fed and passed through the first length folding space below the first clothes clamping mechanism 600, thereby performing a length folding, until the front end of the clothes just passes through the second clothes clamping mechanism 700, the second third crawler device 210 and the fourth crawler device 220 stop running, the second clothes clamping mechanism 700 clamps the clothes and lifts them, the second clothes clamping mechanism 700 and the upper surface of the crawler device below form a second length folding space, the first clothes clamping mechanism 600 releases the clothes and stays above the second conveying mechanism 200, and the clothes complete a length folding.

[0108] Afterwards, the second conveying mechanism 200 and the third conveying mechanism 500 cooperate to convey the clothes that have completed one length folding forward, and the clothes that have completed one length folding are continuously conveyed forward through the second length folding space under the second clothing clamping mechanism 700 to perform a second length folding, until the clothes are transported as a whole to the rear of the second conveying mechanism 200 and supported by the three conveying mechanisms, the second conveying mechanism 200 and the third conveying mechanism 500 stop running, the second clothing clamping mechanism 700 releases the clothes and stays on the upper side of the second conveying mechanism 200, and the clothes have completed the second length folding.
