[0002] Pasting skins on pastries refers to the process of attaching decorative skins to the surface of pastries, including cutting and fitting the decorative skins. The aesthetic appearance and taste of the pastries after skin pasting are both improved, and they are favored by more and more consumers.

[0003] Currently, the process of cutting and fitting decorative skins is usually achieved by combining a manipulator with a mold, a sliding table with a mold, or a rotating platform with a mold. However, when using the combination of a manipulator with a mold or a sliding table with a mold, it is necessary to pick up the skin first and then perform the skin pasting operation, resulting in low production efficiency. Moreover, when replacing the mold in the above three methods, it is necessary to disconnect the connection between the air pipe on the mold and the corresponding air source connecting pipe. After replacing the new mold, the air pipe needs to be connected to the corresponding air source connecting pipe again. Due to the heavy weight of the mold, the installation time is long during replacement, and the installation efficiency is low. In addition, due to the large number of air pipes, the connection is troublesome, and there is a risk of incorrect connection, which requires professional maintenance personnel to operate. Therefore, there is an urgent need for a device with high production efficiency and convenient and fast mold replacement to solve the above problems.

[0024] Figure 1This is a schematic structural diagram of the automatic pastry skin - pasting and forming device in the embodiments of the present application. As Figure 1 shown and referring to Figures 2 to 4 , the embodiments of the present application provide an automatic pastry skin - pasting and forming device 100, which includes a frame 110, a skin - cutting and decorating component 120, a dough conveyor 130, and a pastry conveyor 140 arranged on the frame 110. The skin - cutting and decorating component 120 includes a rotatable rotary mounting plate 121 in the horizontal plane, two quick - change mechanisms 122 arranged at opposite ends of the bottom of the rotary mounting plate 121, and a mold 123 arranged at the bottom of the corresponding quick - change mechanism 122. The dough conveyor 130 and the pastry conveyor 140 are respectively located below the corresponding mold 123. The quick - change mechanism 122 includes an upper mounting plate 1221 fixedly connected to the bottom of the rotary mounting plate 121, a lower mounting plate 1222 fixedly connected to the top of the mold 123, a plurality of medium channels communicating the interiors of the upper mounting plate 1221 and the lower mounting plate 1222, and a connecting structure connecting the upper mounting plate 1221 and the lower mounting plate 1222. The dough conveyor 130 includes a dough conveyor belt 131 and a first lifting mechanism 132 located below the dough conveyor belt. The first lifting mechanism 132 is used to lift the dough conveyor belt 131 upward, so that the dough on the dough conveyor belt 131 moves upward to be extruded and sheared by the cutter of the mold 123 to correspondingly form a decorative skin. The mold 123 above the pastry conveyor 140 is used to attach the decorative skin thereon to the pastry on the pastry conveyor 140.

[0025] The working process of the automatic pastry skin - pasting and forming device 100 in the embodiments of the present application is as follows: The dough conveyor belt 131 conveys the dough to the lower part of the corresponding mold 123. The first lifting mechanism 132 lifts the dough conveyor belt 131 upward, driving the dough to move upward and be extruded by the cutter on the mold 123 to shear out the decorative skin. The rotary mounting plate 121 rotates the mold 123 with the decorative skin to the upper part of the pastry conveyor 140, and the mold 123 attaches the decorative skin to the pastry on the pastry conveyor 140 to form a pastry with a decorative skin. At the same time, the first lifting mechanism 132 lifts again and cooperates with the corresponding mold 123 to achieve skin - cutting. Then, the rotary mounting plate 121 rotates again to achieve skin - pasting. In this way, the cycle is repeated, enabling skin - cutting and skin - pasting to be carried out simultaneously. When replacing the mold 123, the lower mounting plate 1222 is detached from the upper mounting plate 1221, thereby realizing the disassembly of the mold 123. Then, the new mold 123 is installed on the upper mounting plate 1221 through the lower mounting plate 1222 to realize the replacement of the mold 123, and the medium channels in the upper mounting plate 1221 and the lower mounting plate 1222 are automatically connected.

[0026] The automatic pastry skin - pasting and forming device 100 of the present application drives two molds 123 to rotate through a rotating mounting disk 121, and the two molds 123 are respectively used in cooperation with a dough conveyor 130 and a pastry conveyor 140, so that the skin - cutting work and the skin - pasting work can be carried out simultaneously, thereby greatly improving the production efficiency. In addition, through the quick - change mechanism 122 provided, the quick replacement of the mold 123 is realized, the installation efficiency is improved, the replacement difficulty is reduced, and at the same time, due to the relatively fast replacement speed, the pollution generated during the replacement is avoided, and the cleanliness of the device can be maintained. Further, through the installation connection of the upper mounting plate 1221 and the lower mounting plate 1222, the communication of the medium cavity can be realized, avoiding the trouble of connection and the risk of easy connection error when using multiple pipelines for connection.

[0027] In some embodiments of the present application, the dough conveyor 130 and the pastry conveyor 140 are arranged in parallel. When the rotating mounting disk 121 rotates 180 degrees, the mold 123 located above the dough conveyor 130 can reach above the pastry conveyor 140, and the mold 123 above the pastry conveyor 140 can reach above the dough conveyor 130.

[0028] In some embodiments of the present application, as Figure 3 and Figure 4 shown, a plurality of upper medium cavities are formed inside the upper mounting plate 1221. A plurality of medium inlets 1223 communicating with the corresponding upper medium cavities are opened on the upper mounting plate 1221. A plurality of lower medium cavities are formed inside the lower mounting plate 1222, and each lower medium cavity communicates with the corresponding upper medium cavity to form a medium channel. A plurality of medium outlets 1224 communicating with the corresponding lower medium cavities are opened on the lower mounting plate 1222. The connection structure includes a snap - lock mechanism 1225 for pre - fixing the upper mounting plate 1221 and the lower mounting plate 1222 and a plurality of locking structures 1226 for locking the upper mounting plate 1221 and the lower mounting plate 1222.

[0029] In this embodiment, during installation, the lower mounting plate 1222 is aligned with the upper mounting plate 1221, then pre - fixed through the snap - lock mechanism 1225, and finally the upper mounting plate 1221 and the lower mounting plate 1222 are locked using the locking structure 1226. At this time, the upper medium cavities on the upper mounting plate 1221 communicate with the lower medium cavities on the lower mounting plate 1222 one by one to form a medium channel. The medium flows through the medium inlet 1223, the upper medium cavity, the lower medium cavity, and the medium outlet 1224 in sequence to realize different functions. Through the pre - fixing of the snap - lock mechanism 1225, the installation difficulty and labor intensity are reduced, the installation speed can be increased, and the installation efficiency is improved. The locking structure 1226 can be a bolt - nut locking piece.

[0030] In some embodiments of the present application, the medium inlet 1223 is used to communicate with the corresponding gas source. In this embodiment, different medium inlets 1223 can communicate with different gas sources, such as a positive pressure gas source and a negative pressure gas source. The positive pressure gas source can also include positive pressure gas sources with different pressure magnitudes, and the negative pressure gas source can also include negative pressure gas sources with different pressure magnitudes. By communicating different gas sources through the medium inlet 1223, different usage requirements of the mold 123 connected to the medium outlet 1224 can be met.

[0031] In some embodiments of the present application, the quick-change mechanism 122 further includes a positioning structure. The positioning structure includes a positioning hole located on the upper mounting plate 1221 and a positioning post located on the lower mounting plate 1222 that cooperates with the positioning hole. By providing the positioning hole and the positioning post, rapid positioning between the upper mounting plate 1221 and the lower mounting plate 1222 is achieved, saving time and improving the installation efficiency.

[0032] In some embodiments of the present application, the mold 123 includes a main body portion, a cutter located at the bottom of the main body portion, a core that can move vertically within the cutter, a blowing air passage located within the main body portion for blowing off residual skin, and a suction air passage located within the main body portion for adsorbing decorative skin. The blowing air passage communicates with the positive pressure gas source of the medium outlet 1224, and the suction air passage communicates with the negative pressure gas source of the medium outlet 1224. The cutter is used to squeeze and shear the decorative skin when the first lifting mechanism 132 lifts the noodle belt 131 and the noodle dough thereon, and the core is used to push the decorative skin out of the cutter and attach it to the pastry.

[0033] In some embodiments of the present application, as Figure 3 shown, the main body portion includes a frame 1231, a bottom plate 1232 mounted at the bottom of the frame 1231, a negative pressure cavity plate 1233, and a cutter mounting plate. The lower mounting plate 1222 is connected to the upper end of the frame 1231. The bottom plate 1232 is provided with a through first through hole, and a blowing air passage communicating with the first through hole is provided on the side surface of the bottom plate 1232. The cutter mounting plate is arranged on the bottom plate 1232, and a cutter is provided at the bottom of the cutter mounting plate. The cutter passes through the first through hole on the bottom plate 1232. The negative pressure cavity plate 1233 is an inwardly concave structure, sleeved on the cutter mounting plate, and connected to the bottom plate 1232. A cavity is formed between the negative pressure cavity plate 1233 and the cutter mounting plate. A second through hole is provided at the top end of the negative pressure cavity plate 1233, and a suction air passage is provided on its side surface. The core passes through the second through hole of the negative pressure cavity plate 1233 and is in sealing cooperation with the second through hole. The core moves up and down within the cutter driven by the skin-attaching cylinder 1234. The air inlet of the skin-attaching cylinder 1234 communicates with the medium outlet 1224, and this medium outlet 1224 communicates with an external positive pressure gas source.

[0034] In some embodiments of the present application, as Figure 1 and Figure 2As shown, the skin-cutting and appliqué component 120 further includes a motor for driving the rotation of the rotary mounting plate 121 and a slip ring 124 for supplying a power source and / or a signal source to the mold 123. In this embodiment, when the mold 123 rotates, operations such as the extension and retraction, blowing, and suction of the skin-applying cylinder 1234 are carried out simultaneously, and there must be tracheal or electrical wire connections to provide a power source or a signal source. Therefore, the provided slip ring 124 can prevent the tracheal or electrical wires from being wound together during rotation, affecting operations such as skin application. Among them, the slip ring 124 is an electrical component responsible for connecting and transporting energy and signals to the rotating body. The slip ring 124 is usually installed at the rotation center of the device and mainly consists of two major parts: a rotating part and a stationary part. The rotating part is connected to the rotating structure of the device and rotates with it, called the "rotor", and the stationary part is connected to the energy of the fixed structure of the device, called the "stator". The slip ring 124 as a whole relies on the elastic lapping principle, the rolling lapping principle, or the sealing principle, as well as the ingenious design of the motion structure and the sealing structure, the precise manufacturing of parts, and the reasonable selection of materials, etc., to form a stable and reliable rotating connection system. As long as the slip ring 124 is attached to an infinitely rotating device, power energy can be provided to the rotating body, enabling the rotating body to carry out other motions or detect the working conditions under the infinite rotating motion while rotating infinitely.

[0035] In some embodiments of the present application, as Figure 1 shown, the dough conveyor 130 further includes a buffer pad 133 located between the dough conveyor belt 131 and the first lifting mechanism 132. One side edge of the buffer pad 133 is fixedly installed on one side of the mounting frame of the dough conveyor 130. The buffer pad 133 is made of silica gel or rubber. The first lifting mechanism 132 includes a skin-taking cylinder and a first top plate connected to the skin-taking cylinder.

[0036] Skin cutting is achieved by the skin-taking cylinder pushing upward and relying on the impact between the dough conveyor belt 131 and the cutter to squeeze and shear the dough to form a decorative skin. Since the dough conveyor belt 131 is relatively thin, the impact between the cutter and the skin-taking cylinder will cause damage to the cutter and reduce the service life of the cutter. In this embodiment, by providing the buffer pad 133, the impact between the cutter and the skin-taking cylinder can be mitigated, preventing damage to the cutter and extending the service life of the cutter. Moreover, since the texture of the buffer pad 133 is relatively soft, better fitting between the cutter and the dough can be achieved, improving the forming quality of the decorative skin and enabling the shearing of decorative skins with complex shapes.

[0037] In some embodiments of the present application, during skin cutting, the mold 123 has a small swing in the horizontal direction, which plays a role in shearing the dough, making it easier to shear and separate the decorative skin.

[0038] In some embodiments of the present application, as Figure 1As shown in the figure, the pastry conveyor 140 includes a pastry conveyor belt 141 and a second lifting mechanism 142 located below the pastry conveyor belt 141. The second lifting mechanism 142 is used to lift the pastry conveyor belt 141 upward and drive the pastries on the pastry conveyor belt 141 to move upward, so as to reduce the distance between the pastries and the corresponding molds 123. The second lifting mechanism 142 includes a motor, a cam, and a second top plate. The motor drives the cam to rotate, and the cam drives the second top plate to move upward to lift the pastry conveyor belt 141.

[0039] In this embodiment, since there is a certain distance between the mold 123 and the pastries, in order to prevent the decorative skin from drifting during skin pasting, a second lifting mechanism 142 is provided. By using the second lifting mechanism 142 to lift the pastry conveyor belt 141 and the pastries thereon, the distance between the mold 123 and the pastries is reduced, which can prevent the drifting of the decorative skin and improve the quality of the decorative skin attachment. Each time the pastry conveyor belt 141 moves, the cam lifts upward once, repeating in a cycle, with a high degree of automation. Of course, the second lifting mechanism 142 can also be a cylinder.

[0040] In some embodiments of the present application, as Figure 1 shown, the automatic pastry skin pasting and forming device 100 further includes a feeding conveyor 151, a positioning conveyor 152, and a spraying conveyor 160 arranged in sequence. The end of the spraying conveyor 160 is connected to the pastry conveyor 140. The feeding conveyor 151 is used to receive the pastries conveyed by the front-end equipment and perform positioning and sawing on the pastries. The positioning conveyor 152 is used to control the spacing between adjacent pastries. The spraying conveyor 160 includes a spray head 161 for spraying the pastries, a strip conveyor belt 162, and a water receiving tray 163 located below the strip conveyor belt 162. After spraying water on the pastries, it makes it easier for the decorative skin to adhere. And the remaining sprayed water flows into the water receiving tray 163 through the gaps of the strip conveyor belt 162.

[0041] In some embodiments of the present application, the automatic pastry skin pasting and forming device 100 further includes a skin making mechanism. The skin making mechanism includes a multi-stage rolling mechanism connected in sequence. Each stage of the rolling mechanism includes a first rolling roller, a second rolling roller, and a pitch opening and closing mechanism. The pitch opening and closing mechanism is used to adjust the spacing between the first rolling roller and the second rolling roller. As Figure 1 shown, the skin making mechanism includes a first-stage rolling mechanism 171, a second-stage rolling mechanism 172, a third-stage rolling mechanism 173, and a fourth-stage rolling mechanism 174 connected in sequence. The first-stage rolling mechanism 171 is provided with a feeding port.

[0042] In this embodiment, when it is used for the first time, it is necessary to manually assist in guiding the dough sheet from the first-stage rolling mechanism 171 to the fourth-stage rolling mechanism 174. After that, the dough sheet flows into the dough sheet conveyor belt 131 driven by the motor. The operator adds dough according to the amount of dough in the feed inlet, and there is no need to guide the dough sheet again during subsequent production. The dough is put into the feed inlet, and the dough passes through the first-stage rolling mechanism 171, the second-stage rolling mechanism 172, the third-stage rolling mechanism 173, and the fourth-stage rolling mechanism 174 in sequence for rolling to form a dough sheet that meets the requirements. Since the fourth-stage rolling mechanism 174 is adopted, the dough can be rolled into a dough sheet with the required thickness and width, and the thickness and width of the dough sheet are uniform, thus improving the quality of the dough sheet. By adjusting the pitch opening and closing mechanism, the distance between the first pressing roller and the second pressing roller can be adjusted, which can not only gradually reduce the rolling ratio of the dough to ensure the quality of the dough sheet, but also adjust the required thickness of the dough sheet at any time to meet the requirements of different products, greatly improving the practicability of the device.

[0043] In some embodiments of the present application, as Figure 1 shown, the automatic pastry skin pasting and forming device 100 further includes a waste skin recycling conveyor 180, which is located above the dough sheet conveyor 130 and the skin making mechanism, and is used to convey the waste skin at the end of the dough sheet conveyor 130 to the feed inlet of the skin making mechanism.

[0044] In this embodiment, when starting production, residual dough sheets are generated at the end of the dough sheet conveyor belt 131. When it is used for the first time, it is necessary to manually place the residual dough sheets on the waste skin recycling conveyor 180, and then the residual dough sheets automatically flow into the feed inlet of the first-stage rolling mechanism 171. The waste skin recycling conveyor 180 includes a waste skin recycling conveyor belt and waste skin pressing rollers located thereon. The waste skin pressing rollers press the residual dough sheets to prevent the residual dough sheets from slipping. By setting the waste skin recycling conveyor 180, the waste skin can be recycled and utilized, improving the utilization rate of materials, and through automated production, the production efficiency is improved, enabling an operator to operate multiple devices simultaneously.

[0045] In some embodiments of the present application, as Figure 1 shown, the automatic pastry skin pasting and forming device 100 further includes a powder sprinkling mechanism for sprinkling powder on the upper and lower surfaces of the dough sheet. The powder sprinkling mechanism includes a first powder sprinkling mechanism 191 and a second powder sprinkling mechanism 192, which sprinkle powder on the upper and lower surfaces of the dough sheet respectively. By sprinkling powder on the dough sheet, it is prevented that the dough sheet adheres to the dough sheet conveyor belt 131, resulting in skin breakage when the mold 123 picks up the skin, thereby improving the yield rate of the product.

[0046] In some embodiments of the present application, as Figure 1 shown, the automatic pastry skin pasting and forming device 100 further includes a control box and a touch screen, which facilitate the operation of the user through the control box and the touch screen to achieve automated production.
