The end of the upper transverse part 10 close to the center of the limiting sleeve 8 is a disc-shaped structure 13, and all disc-shaped structures 13 are arranged in the limiting space between the top of the thinner part of the bottom of the sliding sleeve 6 and the top of the limiting plate 4. The top of the end of the lower transverse part 12 facing the center of the limiting sleeve 8 is a guide plate 14 inclined upward and facing the center of the limiting sleeve 8. The bottom of the lower transverse part 12 is provided with a radial direction that is the same as the limiting sleeve 8 and is inclined downward relative to the vertical direction, and is wide outside and narrow inside. The arc-shaped cutting plate 15, the top of the middle vertical part 11 is rotatably connected to the lifting mechanism and the vertical plane where its rotation trajectory is located is radially parallel to the limiting sleeve 8. The lifting mechanism is specifically composed of a lower hinged part 16, a middle limiting part 17 and an upper mounting part 18. The lower hinged part 16 is hinged to the top of the middle vertical part 11. The middle limiting part 17 is specifically a long columnar structure with parallel vertical walls on both sides. The upper mounting part 18 is specifically a cylindrical structure and is staggeredly connected to the middle limiting part 17. The inner part thereof is suspended. A threaded sleeve 19, a mounting clip 20, a mounting sleeve 21 and a mounting clip 22 are sleeved from top to bottom on the thinner part of the limiting sleeve 8. An annular limiting plate 22, the bottom of which is tightly pressed against the top of the thicker part of the limiting sleeve 8, and grooves 23 corresponding to the middle limiting part 17 are evenly opened on the outer edge of the annular limiting plate 22, each middle limiting part 17 is arranged in the corresponding groove 23 and the suspended part of the upper mounting part 18 is mounted on the top of the annular limiting plate 22, the upper mounting parts 18 are embedded in the bottom of the mounting sleeve 21, the threaded sleeve 19 is threadedly connected to the top of the limiting sleeve 8, the top of the sliding sleeve 6 is arranged directly above the limiting sleeve 8 and an annular limiting ring 24 is also arranged on its outer edge, and the outer diameter of the annular limiting ring 24 is larger than the inner diameter of the limiting sleeve 8.

[0032] The installation steps of the pleating mechanism are mainly as follows: first, prepare the pleating knife. In this embodiment, there are 24 pleating knives, each of which is composed of an upper transverse part 10, a middle vertical part 11 and a lower transverse part 12. The outer end of the upper transverse part 10 is connected to the top of the middle vertical part 11, and the bottom end of the middle vertical part 11 is connected to the top of the outer end of the lower transverse part. The three can be an integrated structure or a split structure. In this embodiment, in order to facilitate the processing of the equipment, combined Figure 4 The pleating knife structure of this embodiment;

[0033] In this embodiment, in order to achieve the purpose of pleating, a structure is required to perform internal pressure operation on the local area on the top of the bun (combined with the shape of the bun, the local area is in the shape of a line), and at the same time, in order to be able to create an indentation rotation effect (the folds on the bun are not straight but rotating), so in order to achieve the above purpose, the bottom of the lower transverse part 12 is provided with an arc-shaped cutting plate 15 with the same extension direction as the radial direction of the limiting sleeve 8 and inclined downward relative to the vertical direction, and wide outside and narrow inside. Through the above arrangement, when the lower transverse part 12 is driven to move around the axis, the inner end of the lower transverse part 12 first contacts the top of the bun, and then the arc-shaped cutting plate 15 continues to press. Combined with the setting that the arc-shaped pressing plate 15 is inclined and wide outside and narrow inside, the indentation generated is gradually offset from the radial direction to the non-pressed area, thereby generating a rotation effect, and at the same time generating a pleat layering effect (the compressed area extends to the inside of the non-pressed area, so that the non-pressed area adjacent to the compressed area produces the phenomenon of bun skin on both sides, which is closer to the effect of handmade), and the number of pleats can be effectively adjusted according to the number of pleating knives to achieve the purpose of pleating;

[0034] In particular, in this embodiment, in order to combine the hemispherical structure of the dough top so that the wrinkles can be smoothly prepared, the end of the lower transverse portion 12 facing the center of the limiting sleeve 8 is specifically a guide plate 14 that is wide at the top and narrow at the bottom and has a rounded corner at the top;

[0035] Through the above arrangement, when the lower transverse portion 12 is arranged horizontally, the indentation produced on the top of the inner dough in the space surrounded by the pleating knife is uniform and consistent (the guide plate 14 is wide at the top and narrow at the bottom, combined with the spherical shape of the top of the dough, the indentation can be uniform during the initial contact), and when the inner end of the lower transverse portion 12 is driven by an external force to tilt upward and move around the axis, the arc-shaped cutting plate 15 gradually contacts the dough from the inside to the outside, and the indentation produced on the initial guide plate 14 is further expanded. At the same time, combined with its downward tilting characteristic, the dough portion corresponding to the indentation can be gradually tilted and extended downward, thereby producing a laminated pleat effect. Moreover, because the arc-shaped cutting plate 15 is narrow at the inside and wide at the outside, the pleats produced are shallow at the top and deep at the bottom, and the indentation is in the shape of an oblique line, thereby producing a tilted rotation effect, which is more in line with the handmade form.

[0036] In particular, in this embodiment, when the pleating knife is ready, in order to effectively support it and enable it to operate stably, each pleating knife is hoisted on the corresponding hoisting mechanism. In this embodiment, each hoisting mechanism is composed of a lower hinged part 16, a middle limiting part 17 and an upper mounting part 18. In this embodiment, the above three parts are an integrated structure. The lower hinged part 16 is hinged to the top of the middle vertical part 11, so that the pleating knife can be effectively hoisted. After the lower hinged part 16 hoists the pleating knife, it needs to be limited and fixedly installed to avoid instability during operation. In this embodiment, the middle limiting portion 17 is specifically a long columnar structure with vertical walls parallel to each other on both sides. Through this arrangement, it is only necessary to limit the middle limiting portion 17 to stabilize the pleating knife at the bottom thereof. In order to limit all the middle limiting portions 17 and make all the pleating knives form a circle for pleating, in this embodiment, a ring-shaped limiting plate 22 is further provided with evenly arranged grooves 23 corresponding to the middle limiting portion 17 on its outer edge, so that each middle limiting portion 17 can be effectively limited to prevent it from rotating by installing it in the corresponding groove 23.

[0037] In particular, in this embodiment, in order to prevent the middle limiting part 17 from sliding up and down, the upper mounting part 18 is specifically a cylindrical structure and is staggeredly connected to the middle limiting part 17, and its inner part is suspended. After the middle limiting part 17 is installed, it only needs to have its inner wall pressed against the inner wall of the slot 23, so that the suspended part of the upper mounting part 18 is mounted in the annular limiting plate 22, so that the middle limiting part 17 can be prevented from moving downward relative to the sliding limiting plate 22. At the same time, in order to prevent it from moving upward, in this embodiment, a mounting sleeve 21 is further provided, and all the upper mounting parts 18 are embedded in the mounting sleeve 21, and the two ends of the upper mounting part 18 are respectively pressed against the annular limiting plate 22 and the mounting sleeve 21, so that they can be prevented from moving up and down relative to each other;

[0038] In particular, in order to effectively support and limit the annular limiting plate 22 and the mounting sleeve 21, and at the same time enable the pleating knife to effectively contact the top of the dough, in the present embodiment, a limiting sleeve 8 is provided which is cylindrical, has an annular skirt on the outer edge of the bottom end, and is thin at the top and thick at the bottom. The thicker part at the bottom of the limiting sleeve 8 and the annular skirt form an overall structure evenly provided with a vertical L-shaped limiting groove 9 which is radially parallel to the limiting sleeve 8 and penetrates its body. A pleating knife is arranged in each limiting groove 9. The lower transverse portion 12 of the pleating knife is arranged in the skirt. When it is horizontal, the guide plate 14 can effectively make initial contact with the top of the dough. When it is brought to move around the axis, the subsequent arc-shaped cutting plate 14 can also effectively contact the dough, thereby achieving the purpose of pleating. At the same time, the lower transverse portion 12 is suspended in the skirt through the middle vertical portion, and the middle transverse portion 12 is arranged directly above the skirt. In order to effectively set up the annular limiting plate 22 and achieve the purpose of supporting it, in this embodiment, the main part of the limiting sleeve 8 is set to have a thin upper and thick lower structure, so that the annular limiting plate 22 is sleeved on the bottom of the thinner part of the upper part of the limiting sleeve 8, and the installation sleeve 21 is pressed down to make its lower structure in close contact. After being locked by the threaded sleeve 19, the pleating knife can be effectively limited and stably installed;

[0039] In particular, in order to be able to drive the lower transverse part 12 to move around the axis, the present embodiment achieves the purpose of driving the lower transverse part 12 to move around the axis by driving the inner end of the upper transverse part 10. Therefore, a sliding sleeve 6 is also provided. The sliding sleeve 6 is arranged in the limiting sleeve 8 and can slide freely up and down. In the present embodiment, in order to facilitate installation and form a limiting space, the sliding sleeve 6 is specifically thin at both ends and thick in the middle. In order to prevent it from sliding out of the limiting sleeve 8 from top to bottom during use, in the present embodiment, an annular limiting ring 24 is provided on the top of the sliding sleeve 6 (the two are an integrated structure). After the bottom end of the sliding sleeve 6 is installed into the limiting sleeve 8 from top to bottom, in order to form A limiting space is formed. In this embodiment, a central axis 5 of a bottom plate to be limited is provided. After the top end of the central axis 5 penetrates into the sliding sleeve 6 from bottom to top and is connected with a locking nut 7 provided in the top of the sliding sleeve 6, the relative positions of the two can be effectively locked. The limiting space formed by the thinner portion of the limiting plate 4 and the lower portion of the sliding sleeve 6 can effectively limit and drive the upper transverse portion 10. In order to reduce the friction during the driving process, in this embodiment, the end portion of the upper transverse portion 10 close to the center of the limiting sleeve 8 is a disc-shaped structure 13, and all disc-shaped structures 13 are provided in the limiting space between the top of the thinner portion of the bottom of the sliding sleeve 6 and the top of the limiting plate 4.

[0040] Through the above arrangement, when the sliding sleeve 6 moves up and down, all the disc-shaped structures 13 can be limited by the limiting space formed by the limiting plate 4 and the top of the thinner part of the bottom thereof, so that they can be driven to synchronously reciprocate up and down, and then effectively drive the pleating knife to move around the axis to achieve the purpose of pleating;

[0041] The above is the operating principle and installation process of the pleating mechanism of this embodiment.

[0042] In particular, in order to effectively drive the pleating mechanism, in the present embodiment, the first displacement mechanism includes a first screw adjustment mechanism 25 installed on the front end of the machine body 1 for adjusting the height of the pleating mechanism in the vertical direction as a whole. A first cylinder 26 with an output shaft vertically downward is installed on the front end of the upper and lower sliding platforms of the first screw adjustment mechanism 25. The bottom end of the output shaft of the first cylinder 26 is fixedly connected to one end of the first connecting platform 27. In the present embodiment, in order to effectively set up the installation limit sleeve 8, an installation clip 20 is also sandwiched between the threaded sleeve 19 and the installation sleeve 21. The clamping piece 20 is installed on the first connecting platform 27, and its position can be relatively adjusted by bolts, etc. In order to drive the sliding sleeve 6 to complete the pleating purpose, in the present embodiment, a vertical frame 28 is also provided on the top of the first connecting platform 27, and a second cylinder 29 with an output shaft vertically downward is installed at the front end of the vertical frame 28. The output shaft of the second cylinder 29 is connected to one end of the second connecting platform 30 for clamping the thinner part of the top of the sliding sleeve 6. The first cylinder 26 drives the pleating mechanism to move up and down as a whole, and the second cylinder 29 drives all the pleating knives to move around the axis through the sliding sleeve 6.

[0043] Through the above arrangement, the purpose of pleating can be effectively achieved, that is, when the dough moves to the bottom of the pleating mechanism, the pleating mechanism moves downward as a whole under the drive of the first cylinder 26 (in this process, all the pleating knives are spread outward, that is, the second cylinder 29 drives the sliding sleeve 6 downward to the limit, and the outer end of the lower transverse part 12 is tilted outward), and after it moves downward to the set position, the second cylinder 29 drives the sliding sleeve 6 upward to drive the pleating knives to make pleats. After completion, the second cylinder 29 moves downward again until the pleating knives are opened, and the first cylinder 26 drives the device upward as a whole, waiting for the next dough to be transported to complete the entire operation;

[0044] Among them, the first screw adjustment mechanism 25 is composed of a screw, two guide rods, two transverse supports and a sliding platform. Like the traditional screw adjustment mechanism, the middle part of the sliding platform is sleeved on the screw and threadedly connected to it, and its horizontal ends are respectively sleeved on two guide rods for guidance (combined with the attached drawings). Through the above arrangement, the overall height of the pleating mechanism can be effectively adjusted, thereby improving the application range of the equipment.

[0045] After the pleating is completed, it is necessary to drill holes on the top of the dough for later steaming. In order to achieve the above purpose, in the present embodiment, the second displacement mechanism includes a second screw adjustment mechanism 31 (with the same structure as the first screw adjustment mechanism 25) installed on the front end of the body 1 for adjusting the overall vertical height of the drilling device. The front end of the upper and lower sliding platforms of the second screw adjustment mechanism 31 is installed with a third cylinder 32 with an output shaft vertically downward. The bottom end of the output shaft of the third cylinder 32 is fixedly connected to one end of a third connecting platform 33 for installing the drilling device. The third connecting platform 33 is installed with a drilling device. The drilling device is specifically composed of a vertically arranged drilling knife 34 and a driving device 35. The driving device 35 (the driving device 35 is a motor in the present embodiment) is fixedly installed on the third connecting platform 33, and its output shaft is fixedly connected to the vertically arranged drilling knife 34 and drives it to rotate around the axis.

[0046] Through the above arrangement, the top of the dough can be effectively drilled.

[0047] In particular, in order to avoid the drilling position being off-center, in the present embodiment, the auxiliary mechanism includes a third screw adjustment mechanism 36 (with the same structure as the first screw adjustment mechanism 25) horizontally installed in the second conveyor belt 3, and two fourth cylinders 37 with output shafts facing away from each other and parallel to the sliding direction are fixedly installed on the sliding platform of the third screw adjustment mechanism 36, and the outer end of each output shaft of the fourth cylinder 37 is fixedly connected to a vertical connecting plate 38, and the top of each connecting plate 38 is fixedly connected to a mounting plate 39 arranged above the second conveyor belt 3, and each mounting plate 39 is installed with a drive plate 40 with a W-shaped cross-section and vertically arranged at the other end, and the middle parts of the two drive plates 40 are arc-shaped and the centers of the two circles are horizontally arranged and facing each other.

[0048] Through the above arrangement, the two driving plates 40 can effectively drive the dough to the bottom of the drilling device, and the positions of the two driving plates 40 relative to the second conveyor belt 3 can be adjusted by adjusting the third screw adjustment mechanism 36, thereby achieving the purpose of adaptive adjustment.

[0049] Example 2

[0050] The main structure of the device in this embodiment is similar to that of Embodiment 1, with the main difference being that the device provided in this embodiment also includes a clamping device which is arranged on the outside of the bottom end of the drilling knife 34, fixedly mounted on the bottom of the third connecting platform 33 and used to clamp the top of the dough after pleating and assist in generating a skirt when drilling.

[0051] By providing a clamping device, a small skirt can be formed on the top of the bun, so that the bun can be more in line with the shape of manual preparation.

[0052] In particular, in the present embodiment, the clamping device comprises two clamping members 41 arranged opposite to each other (suspended by a suspension plate below the bottom of the second displacement mechanism), the clamping member 41 is specifically a semicircular hourglass structure formed by connecting the upper semicircular inclined plate and the lower semicircular inclined plate at both ends, the centers of the semicircles formed in the middle of the two clamping members 41 face each other, and a driving member 42 is further installed on the outer wall of the clamping member 41, each driving member 42 is respectively connected to a driving mechanism 43 that can drive the two clamping members 41 to move relative to each other (the driving mechanism 43 can be a worm gear structure or a device composed of two cylinders respectively connected to one driving member 42, as long as the purpose of making the two clamping members 41 move relative to each other is achieved).

[0053] Through the above arrangement, a skirt can be effectively formed on the top of the dough.

[0054] In particular, in order to effectively control the shape of the skirt at the top of the dough, in the present embodiment, the bottom end of the drilling knife 34 is an inverted isosceles trapezoidal structure, in which the midline coincides with the center of the two clamping members 41, and the inclination angle of the upper inclined plate is not greater than the inclination angle of the side wall at the bottom end of the drilling knife 34, and the bottom width of the drilling knife 34 is less than the diameter of the circle formed in the middle after the two clamping members 41 contact.

[0055] Through the above arrangement, the skirt at the top of the dough can be effectively controlled to make it narrow at the top and wide at the bottom, which is closer to the actual shape prepared by hand.

[0056] The above setting can effectively control the shape of the skirt, but in the actual production process, the drilling effect is limited. Therefore, in order to improve the drilling quality, in this embodiment, the bottom of the drilling tool 34 is also provided with a pore knife 44 whose width is smaller than the bottom width of the drilling tool 34.

[0057] Through the above arrangement, holes can be effectively drilled on the top of the dough, which is convenient for later steaming of the dough.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
