Technical Field

[0001] This application relates to the field of food processing, and in particular, to an automatic folding mechanism for louvers. Background Art

[0002] After the louvers are processed, they need to be folded and then transported for subsequent processes such as cutting.

[0003] Currently, after the louvers are processed, they are conveyed to a workbench by a conveyor belt, and then manually folded and formed. As shown in Figure 1 , there are a first folding end and a second folding end after the louvers are folded. The manual folding method is inefficient and has a low degree of automation, and there is room for improvement. Summary of the Invention

[0004] In order to improve the automation degree of louver folding and improve the folding efficiency, this application provides an automatic folding mechanism for louvers.

[0005] The automatic folding mechanism for louvers provided by this application adopts the following technical solution:

[0006] An automatic folding mechanism for louvers includes a machine body. Two mounting plates are oppositely arranged on the machine body. A storage plate for storing louvers is arranged between the two mounting plates on the machine body, and the louvers are vertically conveyed downward above the storage plate. A first clamping member and a second clamping member are slidably arranged on the mounting plate. The first clamping member and the second clamping member alternately clamp the louvers. A first sliding groove and a second sliding groove are formed on the mounting plate. Both the first sliding groove and the second sliding groove are inclined. The upper ends of the first sliding groove and the second sliding groove are communicated. The first clamping member slides in the first sliding groove, and the second clamping member slides in the second sliding groove. The first clamping member clamps the louvers and folds them to form a first folding end, and the second clamping member clamps the louvers and folds them to form a second folding end.

[0007] By adopting the above technical solution, when the louvers are conveyed from the conveyor belt to the storage plate, the louvers are conveyed vertically downward. In the initial state, the first clamping member is located at the connection of the first sliding groove and the second sliding groove, and the first clamping member clamps the louvers. Then, by sliding along the first sliding groove, the louvers can be driven to fold to form a first folding end. Then, the second clamping member is located at the connection of the first sliding groove and the second sliding groove, and the second clamping member clamps the louvers and slides along the second sliding groove, so as to drive the louvers to fold to form a second folding end. The first clamping member and the second clamping member reciprocate, and the louvers can be continuously driven to perform folding operations. Moreover, when the first clamping member is at the highest position of the first sliding groove, the second clamping member is at the lowest position of the second sliding groove; when the first clamping member is at the lowest position of the first sliding groove, the second clamping member is at the highest position of the second sliding groove. In this way, the automatic folding of the louvers is realized, which helps to improve the folding efficiency.

[0008] Preferably, a conveying chain is wound around the installation plate in the first sliding groove and the second sliding groove. A first sliding block and a second sliding block are fixedly connected to the conveying chain. The first clamping member is arranged on the first sliding block, and the second clamping member is arranged on the second sliding block. A driving sprocket is rotatably arranged on the installation plate. The driving sprocket is engaged with the conveying chain, and a servo motor for driving the driving sprocket to rotate is arranged on the installation plate.

[0009] By adopting the above technical solution, the servo motor drives the driving sprocket to rotate, and the sprocket drives the conveying chain to move, so as to realize the sliding of the first sliding block and the second sliding block. The first sliding block and the second sliding block can drive the corresponding clamping members to slide, realizing the folding of the louvers.

[0010] Preferably, both the first clamping member and the second clamping member are set as jaw cylinders, and the jaws of the jaw cylinders perform clamping and opening actions.

[0011] By adopting the above technical solution, the first clamping member and the second clamping member are set as jaw cylinders. The jaws on the jaw cylinders can clamp the louvers, and then during the sliding process, the louvers can be driven to move along a track to realize folding, and then the jaws open and reset.

[0012] Preferably, a plurality of guide posts are arranged on the installation plate. The conveying chain is wound around all the guide posts. A cover plate is installed on the installation plate, and the cover plate covers all the guide posts. A limiting plate is further arranged on the circumferential side of the installation plate where the cover plate is located. The first sliding groove and the second sliding groove are formed between the limiting plate and the guide posts. A sprocket group for driving the conveying chain is also arranged on the installation plate.

[0013] By adopting the above technical solution, actually, the first sliding groove and the second sliding groove are in an arc triangular shape. The arrangement of the guiding columns makes the shape of the conveying chain in an arc triangular shape, that is, finally makes the moving track of the gripper cylinder driving the louver in an arc shape, which is convenient for the smooth folding of the louver. Through the cover plate, the guiding columns and the conveying chain can be shielded to ensure the aesthetics of the mechanism.

[0014] Preferably, guiding baffles are arranged on both sides of the machine body where the storage plate is located.

[0015] By adopting the above technical solution, the guiding baffles can guide and limit the louvers to ensure that the louvers can be neatly folded on the storage plate.

[0016] Preferably, a driving cylinder is installed on the machine body, and the end of the piston rod of the driving cylinder is fixedly connected to the storage plate.

[0017] By adopting the above technical solution, during the folding process of the louvers, since the lowest end of the moving track of the gripper cylinder is fixed, when the folded louvers gradually increase in height, the gripper cylinder will contact the folded louvers, affecting the folding operation. Therefore, the driving cylinder will drive the storage plate to gradually descend to ensure that the gripper cylinder will not touch the already folded louvers.

[0018] Preferably, an air spray pipe is arranged on the machine body. There are two air spray pipes arranged oppositely. The air spray pipes spray moisture onto the louvers. A rotating shaft is rotatably arranged at the air jet outlet of the air spray pipe. A first baffle is arranged on the rotating shaft. Two second baffles are also symmetrically arranged along the first baffle on the rotating shaft. The included angle between the first baffle and any one of the second baffles is greater than 120 degrees. The air jet outlet of the air spray pipe is arranged in an arc shape, adapting to the rotating track of the first baffle.

[0019] By adopting the above technical scheme, during the folding process of the shutter, the moisture in the middle of the folded part of the shutter will not be lost due to the folding, but the moisture at the edge of the shutter will gradually dissipate. In order to ensure the taste and quality of the shutter, the air jet pipe is used to continuously spray moisture to the edge of the shutter to ensure the moisture at the edge of the shutter during the folding process. In the process of the air jet pipe spraying moisture, the rotating shaft rotates back and forth, that is, the first baffle plate makes a reciprocating motion. When the first baffle plate moves to one side of the air jet port of the air jet pipe, the moisture sprayed from the air jet pipe will flow along the first baffle plate and one of the second baffle plates and spray to one side of the shutter, and then when the first baffle plate rotates to the other side of the air jet port, the moisture The flow area of the air changes, and in practice, when the first baffle moves back and forth, the flow area of the moist air can cover the length range of the edge of the louver, ensuring the moisture at the edge of the louver; and because the sprayed moisture is in mist form, the moisture will diffuse in the folded area, which can further humidify the louver to prevent the louver from drying out and affecting the taste; in addition, the louver may have wrinkles during the folding process, and when the moist air is sprayed, a certain amount of wind force will be generated, which can remove the wrinkles on the louver and make the louver fold smoothly, and during the reciprocating rotation of the first baffle, the direction of the wind force is also in a reciprocating process, and the wind force covers a wide area, thereby improving the effect of removing wrinkles.

[0020] Preferably, a driving gear is coaxially fixed on the rotating shaft, a driving rack is slidably provided on the body, the driving rack is meshed with the driving gear, and the body is rotatably connected to a linkage wheel, a connecting rod is eccentrically provided on the linkage wheel, one end of the connecting rod is hinged with the linkage wheel, and the other end of the connecting rod is hinged with the driving rack; the sprocket group includes three driven sprockets, the three driven sprockets are all meshed with the conveying chain, and the three driven sprockets are distributed at the triangle of the conveying chain, the first connecting shaft is rotatably connected to the mounting plate, the first connecting shaft is coaxially fixed with the first sprocket, one of the driven sprockets located on the bottom side is coaxially fixed with the first connecting shaft, and the mounting plate is also rotatably connected to the second connecting shaft, the second sprocket is coaxially fixed on the second connecting shaft, a transmission chain is wound around the first sprocket and the second sprocket, and the linkage wheel is coaxially fixed on the second connecting shaft.

[0021] By adopting the above technical solution, when the blinds are folding, the conveying chain will drive the driven sprocket to rotate, the driven sprocket will drive the first sprocket to rotate synchronously, the first sprocket will drive the second sprocket to rotate through the transmission chain, the second sprocket will drive the interlocking wheel to rotate synchronously, when the interlocking wheel rotates, it will drive the connecting rod to move, the connecting rod will drive the driving rack to slide, the driving rack will drive the driving gear to rotate, thereby realizing the rotation of the rotating shaft and the rotation of the first baffle. Since the conveying chain moves back and forth, the chain will rotate back and forth, that is, the first baffle will slide back and forth at the jet outlet of the jet pipe.

[0022] Preferably, rotary cylinders are provided on both the first sliding block and the second sliding block, and the jaw cylinder is fixed on the rotating shaft of the rotary cylinder. During the process of the jaw cylinder driving the louvers to fold, the rotary cylinder drives the jaw cylinder to swing reciprocally; the rotation directions of the two rotating shafts are always the same.

[0023] By adopting the above technical solution, the sliding trajectories of the first sliding block and the second sliding block are arc-shaped. Therefore, during the sliding process of the sliding block, it will tilt. When the jaw cylinder finishes folding the louvers, the two jaws need to open and disengage from the louvers. However, if the jaws are tilted at this time, they may interfere with the louvers. Therefore, the use of the rotary cylinder can ensure that the two jaws are horizontal, facilitating the disengagement of the jaw cylinder and the louvers; when the jaw cylinder clamps the louvers for folding, the two jaws do not clamp the louvers tightly. The two jaws only surround the periphery of the louvers and there is a gap between them and the louvers. Then, the louvers are driven to move along a certain trajectory for folding. During the process of driving the louvers to move, the rotary cylinder drives the jaw cylinder to swing reciprocally. Therefore, the jaws will drive the louvers to swing continuously. On the one hand, it can eliminate the wrinkles on the louvers, and on the other hand, it can make the slag adhering to the louvers fall off; after the slag falls off, under the action of the air jet from the air jet pipe, the slag can be blown off from the surface of the louvers; because the rotation directions of the two rotating shafts are the same, the jet directions of the two air jet pipes are staggered. That is, during the blowing process, the wind force acting surface is wide, which can improve the blowing effect of the slag.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. First, the first clamping member clamps the louvers and drives the louvers to fold to the first folding end, and then the second clamping member drives the louvers to fold to the second folding end. Repeating this process can achieve the automatic folding of the louvers, which helps to improve the folding efficiency of the louvers;

[0026] 2. With the help of the air jet pipe, moisture can be blown to the edges of the louvers, which can ensure the moisture of the edges of the louvers. Due to the folding of the middle part of the louvers, the moisture will not be lost too quickly, which can ensure the quality of the louvers. And due to the rotation of the rotating shaft, the first baffle will rotate reciprocally at the air jet outlet of the air jet pipe, changing the jet flow direction of the air jet pipe. During the rotation of the first baffle, the jet area can cover the length range of the edges of the louvers;

[0027] 3. During the folding process, the rotary cylinder will drive the jaw cylinder to swing reciprocally. During the swinging process, the louvers will be driven to shake. On the one hand, it can eliminate the wrinkles on the surface of the louvers, and on the other hand, it can make the slag adhering to the louvers fall off. And after the slag falls off, under the action of the air jet from the air jet pipe, the slag is blown off from the surface of the louvers. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0037] The following further describes this application in detail with reference to the attached Figures 2 - 8 drawings.

[0038] The embodiment of this application discloses an automatic folding mechanism for louvers.

[0039] Refer to Figure 2, the automatic louver folding mechanism includes a body 1, on which a mounting plate 2 is relatively fixed. A folding space 21 for folding the louvers is formed between the two mounting plates 2 of the body 1. A storage plate 3 is arranged to lift between the two mounting plates 2 of the body 1. The storage plate 3 is used to store the folded louvers. The louvers are transported by a conveying device and enter the folding space 21 in the vertical direction. A first clamping member 4 and a second clamping member 5 are slidably arranged on the mounting plate 2. Both the first clamping member 4 and the second clamping member 5 are set as jaw cylinders 41. The jaws of the jaw cylinder 41 perform clamping and opening actions. The first clamping member 4 and the second clamping member 5 alternately clamp the louvers. On the opposite sides of the two mounting plates 2, a first sliding groove 22 and a second sliding groove 23 are respectively formed. Both the first sliding groove 22 and the second sliding groove 23 are inclined. The upper ends of the first sliding groove 22 and the second sliding groove 23 are connected. The first clamping member 4 slides in the first sliding groove 22, and the second clamping member 5 slides in the second sliding groove 23.

[0040] When the louvers are transported from the conveying device above the folding space 21, the louvers are transported vertically downward. The first clamping member 4 is located at the connection of the first sliding groove 22 and the second sliding groove 23, and at this time, the second clamping member 5 is located at the lowest end of the second sliding groove 23. The first clamping member 4 clamps the louvers and drives the louvers to move along a certain track, and folds to form a first folding end. When the first clamping member 4 drives the louvers to move, the second clamping member 5 gradually moves to the connection of the first sliding groove 22 and the second sliding groove 23. The second clamping member 5 clamps the louvers and moves along a certain track, and folds to form a second folding end. Repeating this process, the automatic folding of the louvers can be realized. In this way, it helps to improve the folding efficiency of the louvers.

[0041] Refer to Figure 2 and Figure 3 , a number of guide posts 24 are distributed on the mounting plate 2. A conveying chain 25 is wound around all the guide posts 24. The conveying chain 25 is arranged in a closed loop and has an arc triangular shape. A cover plate 26 is fixedly connected to the mounting plate 2. The cover plate 26 covers all the guide posts 24 to ensure aesthetics. A limiting plate 27 is also fixedly connected to the periphery of all the guide posts 24 of the mounting plate 2. The first sliding groove 22 and the second sliding groove 23 are formed between the limiting plate 27 and the guide posts 24. A sprocket group for driving the conveying chain 25 to move is also arranged on the mounting plate 2. The sprocket group includes three driven sprockets 6, all of which are engaged with the conveying chain 25 and are respectively located at the three corners of the conveying chain 25.

[0042] Refer to Figure 2 , Figure 3 and Figure 4, a first sliding block 7 and a second sliding block 8 are fixedly connected to the conveying chain 25. Since the structures of the first sliding block 7 and the second sliding block 8 are the same, only the first sliding block 7 is shown as an example in the figure. The first clamping member 4 is arranged on the first sliding block 7, and the second clamping member 5 is arranged on the second sliding block 8. Since both sliding blocks are fixed on the conveying chain 25, the first clamping member 4 and the second clamping member 5 move synchronously. When the first clamping member 4 slides from the highest end to the lowest end of the first sliding groove 22, the second clamping member 5 slides from the lowest end to the highest end of the second sliding groove 23. A transmission shaft 9 is rotatably connected between the two mounting plates 2. Two driving sprockets 91 are coaxially fixed to the transmission shaft 9. The two driving sprockets 91 correspond to the two conveying chains 25 one by one. The bottom corner of the conveying chain 25 is wound around the driving sprocket 91. A servo motor 11 is also fixedly installed on the machine body 1, and the output shaft of the servo motor 11 is fixedly connected to the transmission shaft 9.

[0043] The servo motor 11 drives the transmission shaft 9 to rotate, drives the driving sprocket 91 to rotate, and the driving sprocket 91 drives the conveying chain 25 to move, so as to realize the sliding of the first sliding block 7 and the second sliding block 8. The first sliding block 7 and the second sliding block 8 can drive the corresponding clamping jaw cylinders 41 to slide, realizing the folding of the louver; and the conveying chain 25 makes a reciprocating motion, that is, driving the first sliding block 7 and the second sliding block 8 to make a reciprocating sliding motion in the corresponding sliding grooves.

[0044] Two guiding baffles 12 are symmetrically installed on the upper part of the machine body 1. The two guiding baffles 12 are located on both sides of the storage plate 3. The guiding baffles 12 guide and limit the louver, which can ensure that the louver can be neatly folded on the storage plate 3.

[0045] A driving cylinder 13 is fixedly installed on the lower side of the machine body 1. The driving cylinder 13 is arranged vertically upward, and the end of the piston rod of the driving cylinder 13 is fixedly connected to the storage plate 3. During the folding process of the louver, since the lowest position of the sliding track of the clamping jaw cylinder 41 is fixed, when the folded louver gradually increases in height, the clamping jaw cylinder 41 will contact the louver, affecting the folding effect. Therefore, the driving cylinder 13 will drive the storage plate 3 to gradually descend to ensure that the clamping jaw cylinder 41 does not touch the folded louver.

[0046] The implementation principle of an automatic louver folding mechanism in an embodiment of the present application is as follows: The louver is conveyed to the folding mechanism and enters the folding space 21 in the vertical direction. The first clamping member 4 clamps the louver and drives the louver to move along the track of the first sliding groove 22, folding it into a first folding end. Then the second clamping member 5 clamps the louver and drives the louver to move along the track of the second sliding groove 23, folding it into a second folding end. Repeating this process, the automatic folding of the louver can be realized, which helps to improve the folding effect.

[0047] Embodiment 2

[0048] Refer toFigure 5 and Figure 6 Differently from Embodiment 1, in the embodiment of the present application, a guiding baffle 12 is not provided on the machine body 1, and an air injection pipe 10 is installed on the machine body 1. There are two air injection pipes 10 which are arranged oppositely, and the air injection pipes 10 spray moisture to the edge of the hundred-leaf. Two rotating shafts 20 are rotatably arranged on the machine body 1. The two rotating shafts 20 correspond to the two air injection pipes 10 one by one, and the rotating directions of the two rotating shafts 20 are always the same. A first baffle 201 is fixedly connected to the rotating shaft 20, and two second baffles 202 are also fixed on the rotating shaft 20. The two second baffles 202 are symmetrically arranged along the first baffle 201. The included angle between the first baffle 201 and any one of the second baffles 202 is greater than 120 degrees. The air jet openings of the air injection pipes 10 are arc-shaped and are adapted to the rotation trajectory of the first baffle 201. When the first baffle 201 rotates at the air jet opening of the air injection pipe 10, the flow direction of the air flow can be changed.

[0049] The hundred-leaf needs to maintain moisture to ensure the taste. After the hundred-leaf is folded, the moisture in the middle is not easy to lose, but the moisture at the edge of the hundred-leaf is in contact with the air all the time, so the moisture loss is relatively fast. In order to ensure the moisture of the hundred-leaf, the air injection pipe 10 sprays moisture, and the moisture will adhere to the edge of the hundred-leaf to ensure the moisture of the hundred-leaf. In practice, the rotating shaft 20 makes a reciprocating motion, that is, the first baffle 201 makes a reciprocating motion. When the first baffle 201 just moves to one side of the air jet opening, the moisture will flow along the first baffle 201 and one of the second baffles 202 and spray to the edge of the hundred-leaf. When the first baffle 201 is located in the middle position of the air jet opening, the air flow can flow out from both sides of the first baffle 201. In practice, referring to Figure 7 , during the reciprocating movement of the first baffle 201, the flow area of the air flow changes continuously, and the flow area can cover the length range of the edge of the hundred-leaf to ensure the moisture of the edge of the hundred-leaf. And after the moisture is sprayed out, part of it is in a misty state, and the misty moisture will diffuse in the folding space 21 to further humidify the hundred-leaf. In addition, during the folding process of the hundred-leaf, there may be wrinkles. When spraying moisture, a certain wind force will be generated, and the wind force acting on the wrinkles can remove the wrinkles. And during the rotation of the first baffle 201, the air flow is in a sweeping state. Therefore, when the air flow sweeps to the wrinkles, the wind force will change. Compared with the case where the wind force is constant and blows directly on the wrinkles, the effect of removing wrinkles is better.

[0050] Referring to Figure 5 and Figure 8, a first connecting shaft 30 is rotatably connected to the mounting plate 2 in the horizontal direction. A first sprocket 301 is coaxially fixed on the first connecting shaft 30. The driven sprocket 6 on one of the bottom sides is coaxially fixed to the first connecting shaft 30. A second connecting shaft 40 is also rotatably connected to the mounting plate 2. A second sprocket 401 is coaxially fixed on the second connecting shaft 40. A transmission chain 402 is wound around the first sprocket 301 and the second sprocket 401. The diameter of the second sprocket 401 is larger than that of the first sprocket 301. A driving gear 203 is coaxially fixed on the rotating shaft 20. A driving rack 50 is slidably connected to the machine body 1. The driving rack 50 and the driving gear 203 are engaged. A linkage wheel 403 is also coaxially fixed on the second connecting shaft 40. A connecting rod 60 is hinged to the linkage wheel 403. The hinge point of the connecting rod 60 and the linkage wheel 403 is eccentrically arranged with respect to the linkage wheel 403. The other end of the connecting rod 60 is hinged to the driving rack 50.

[0051] When the louver is folded, the conveyor chain 25 drives the driven sprocket 6 to rotate. The driven sprocket 6 drives the first sprocket 301 to rotate synchronously. The first sprocket 301 drives the second sprocket 401 to rotate through the transmission chain 402. The second sprocket 401 drives the linkage wheel 403 to rotate synchronously. The linkage wheel 403 drives the driving rack 50 to slide through the connecting rod 60, thereby realizing the rotation of the driving gear 203. The driving gear 203 realizes the rotation of the first baffle 201 through the rotating shaft 20. Since the conveyor chain 25 moves reciprocally, the first baffle 201 also rotates reciprocally accordingly.

[0052] Refer to Figure 4 , rotary cylinders 70 are installed on both the first sliding block 7 and the second sliding block 8. A connecting plate 701 is fixedly connected to the rotating shaft 20 of the rotary cylinder 70. The clamping jaw cylinder 41 is fixedly installed on the connecting plate 701. During the process of the clamping jaw cylinder 41 driving the louver to move, the rotary cylinder 70 drives the clamping jaw cylinder 41 to swing reciprocally.

[0053] The sliding trajectories of the first sliding block 7 and the second sliding block 8 are arc-shaped. Therefore, during the sliding process of the sliding blocks, they will tilt. When the gripper cylinder 41 drives the louver to be folded, the two grippers need to open and separate from the louver. However, if the grippers are tilted at this time, they may interfere with the louver. Therefore, the rotary cylinder 70 can ensure that the two grippers are horizontal, facilitating the separation of the gripper cylinder 41 and the louver; when the gripper cylinder 41 holds the louver for folding, the two grippers do not clamp the louver tightly. The two grippers only surround the periphery of the louver, with a gap between them and the louver, and then drive the louver to move along a certain trajectory for folding. During the process of driving the louver to move, the rotary cylinder 70 drives the gripper cylinder 41 to swing reciprocally. Therefore, the grippers will drive the louver to swing continuously. On the one hand, it can eliminate the wrinkles on the louver, and on the other hand, it can make the slag adhering to the louver fall off; after the slag falls off, under the action of the air jet from the air jet pipe 10, the slag can be blown off from the surface of the louver; since the rotation directions of the two rotating shafts 20 are the same, the jet directions of the two air jet pipes 10 are staggered. That is, during the blowing process, the wind force acts on a wide area, which can improve the blowing effect of the slag.

[0054] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
