Description

Technical Field

[0001] The present invention relates to the technical field of food production, and particularly to a tart shell production line and a method for producing tart shells. Background Art

[0002] In the field of food processing, the forming process of egg tart shells is a key link affecting their taste and quality. Traditional egg tart shell production mostly adopts a one-step forming method using a die head stamping. However, due to the one-step die head stamping method, the obtained egg tart shells have a firm texture and poor taste.

[0003] Therefore, a method of using multiple die heads to sequentially stamp the egg tart shells is designed. The texture of this method is relatively soft, but compared with handmade ones, its layering is still insufficient.

[0004] Based on the above problems, there is a Chinese invention patent with the publication number CN115363065 A, which discloses a tart shell forming method and its forming production line. The dough is fed by multiple feeding units. After the feeding is completed, a stamping and forming unit or a rotary trimming device is provided to extrude the inner side of the tart shell, and finally a complete tart shell is obtained. Moreover, the obtained tart shell has a soft texture and rich layering.

[0005] However, it is found in actual applications that although this production line significantly improves the layering problem, the finished product still has the limitation of insufficient softness. The specific reason is that: finally, stamping or extrusion is still required to ensure the complete shape of the inner side of the tart shell, but it is precisely this stamping and extrusion that will cause the originally soft dough fed by the feeding unit to become firm again. Summary of the Invention

[0006] Aiming at the deficiencies in the prior art, the present invention provides a tart shell production line and a method for producing tart shells, which solve the technical problem that the egg tart shells produced by the existing tart shell production line still have insufficient softness.

[0007] According to an embodiment of the present invention, a tart shell production line includes:

[0008] A pre-stamping device: provided with a stamping head that moves in the vertical direction;

[0009] A first feeding device: including a rotating device and a first feeding mechanism arranged above the rotating device. The first feeding mechanism is provided with a feeding head that swings or moves in the horizontal direction;

[0010] At least one double-rod feeding device: including a rotating device and a double-rod feeding mechanism arranged above the rotating device. The double-rod feeding mechanism is provided with a set of feeding heads that swing or move in the horizontal direction; the set of feeding heads includes two feeding heads that swing or move away from each other, and perform feeding at multiple different heights and different strokes;

[0011] Transfer device: The pre-stamping device, the first material feeding device, and at least one double-rod material feeding device are sequentially arranged on the transfer device;

[0012] The transfer device is evenly distributed with bearing plates, the bearing plates move along the conveying direction of the transfer device, the stamping head, the first material feeding mechanism, and all the double-rod material feeding mechanisms are arranged on the upper side of the bearing plates, and all the rotating devices are arranged on the lower side of the bearing plates.

[0013] The technical principle of the present invention is as follows: During use, the dough is first pre-pressed so that the dough adheres closely to the bottom of the egg tart cup, and then it enters the first material feeding device for the first material feeding, which can also be called pre-material feeding, in order to quickly form a depression on the dough. And during the material feeding process, a depression close to the shape of the egg tart crust is quickly formed. Then it enters the double-rod material feeding device, and two material feeding heads moving away from each other are used to perform multiple material feedings on the egg tart crust. Among them, multiple material feedings can be completed by the same double-rod material feeding device at different heights, or by multiple double-rod material feeding devices at different heights; after completion, the final egg tart crust can be obtained without performing forming stamping or extrusion. Therefore, the egg tart crust produced by it has almost the same softness as the hand-made egg tart crust.

[0014] Because the material feeding method of the double-rod material feeding device adopted in this application is symmetric, the shape of each material feeding is controllable. Then, by cooperating with material feedings at different heights and different strokes, the inner shape of the egg tart crust can be directly processed into the required shape during the material feeding process.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By using the first material feeding device in cooperation with at least one double-rod material feeding device to perform material feeding on the egg tart crust, a finished egg tart crust can be obtained, which solves the technical problem that the egg tart crust produced by the existing egg tart crust production line still has insufficient softness.

[0016] Preferably, because the process of forming stamping is reduced, it has the effects of reducing the production line cost and improving the production efficiency.

[0017] Preferably, the material feeding heads of the double-rod material feeding device adopt a horizontal movement mode, and their shapes are easier to control, and the inner shape of the produced egg tart crust is better.

[0018] Furthermore, processing positions are evenly distributed in a rectangle on the bearing plates, stamping heads are evenly distributed in a rectangle on the pre-stamping device, material feeding heads are evenly distributed in a rectangle on the first material feeding device, a group of material feeding heads are evenly distributed in a rectangle on the double-rod material feeding device, and a corresponding rotating device is provided under each material feeding head of the first material feeding device and each group of material feeding heads of the double-rod material feeding device; the number of a row of the processing positions is the same as the number of a row of stamping heads, a row of material feeding heads, and a row of groups of material feeding heads.

[0019] By making the number of a row of processing positions the same as the number of a row of punching heads, a row of material shifting heads and a row of material shifting head groups, the original single production production line is expanded into multiple production production lines, and the pre-punching device, the first material shifting device and all the double-rod material shifting devices are connected through a conveying device, so that the above devices can work perfectly together, which can effectively improve work efficiency.

[0020] Furthermore, the first material shifting mechanism includes a support frame and a moving mechanism arranged on the support frame;

[0021] The moving mechanism includes a driving motor and a screw mechanism connected to the driving motor, and the driving motor and the screw mechanism are both installed at one end of the support frame; movable rods are evenly distributed along the width direction of the support frame, and the movable rods can move along the length direction of the support frame, and one end of all the movable rods is connected to a transmission plate, and the transmission plate is connected to the screw mechanism; a row of the material diverting heads are installed on the same movable rod.

[0022] The evenly distributed movable rods are driven by a driving motor and a screw mechanism, and the movable rods are evenly provided with feeding heads, so that one driving motor controls multiple feeding heads, thereby realizing the simultaneous production of multiple egg tart crusts, and effectively improving the working efficiency of the first feeding mechanism.

[0023] Furthermore, the double-rod material-moving mechanism comprises a support frame and two moving mechanisms symmetrically arranged on the support frame;

[0024] The moving mechanism includes a driving motor and a screw mechanism connected to the driving motor, and the two driving motors and the screw mechanism are respectively installed at two end positions of the support frame; movable rod groups are evenly distributed along the width direction of the support frame, and each of the movable rod groups includes two parallel movable rods, and the movable rods can move along the length direction of the support frame, and one end of a movable rod in all the movable rod groups is connected to a transmission plate, and the other end of another movable rod in all the movable rod groups is also connected to a transmission plate, and the two transmission plates are respectively connected to the screw mechanisms of the two moving mechanisms; the two material shifting heads of a row of the material shifting head groups are respectively installed on the two movable rods of a movable rod group.

[0025] The evenly distributed movable rods are driven by a driving motor and a screw mechanism, and a feeding head group is evenly arranged on the movable rods, so that one driving motor controls multiple feeding heads, thereby realizing the simultaneous production of multiple egg tart crusts, and effectively improving the working efficiency of the double-rod feeding device.

[0026] Furthermore, all the rotating devices of the first material shifting device or the double-rod material shifting device are provided with a common lifting frame, and the lifting frame is provided with a rotating motor, and the rotating motor is transmission-connected to at least one row of the rotating devices.

[0027] By driving multiple rotating devices through a rotating motor, in cooperation with the first material shifting device or the double-rod material shifting device, multiple egg tart crusts can be produced simultaneously, effectively improving the working efficiency of the double-rod material shifting device.

[0028] Furthermore, the rotating device includes a rotating tube, a rotating disk arranged on the top of the rotating tube, and a driving gear arranged at the bottom of the rotating tube. The driving gear is connected to the rotating motor. A bearing seat is provided on the rotating tube, and the bearing seat is installed on the lifting frame. Each rotating disk is aligned with a processing position. A mounting hole is provided at the supporting plate corresponding to the processing position. A rotating ring is provided in the mounting hole, and the bottom of the rotating ring is connected to the rotating disk.

[0029] The rotating ring is connected to the rotating disk to ensure that the rotating device can drive the egg tart cup to rotate, thereby avoiding the situation where the rotating ring fails to follow the rotation of the rotating disk, that is, avoiding the situation of losing steps. Once losing steps occurs, it will lead to failure in the material removal of the egg tart crust, resulting in unqualified egg tart crust.

[0030] Furthermore, a lifting device is provided on both sides of the lifting frame and the supporting frame, and the lifting device includes a height plate and an upper motor screw module arranged on the top of the height plate and a lower motor screw module arranged at the bottom of the height plate. The bottom of the upper motor screw module is connected to the supporting frame, and the top of the lower motor screw module is connected to the lifting frame.

[0031] By setting a lifting device, it is possible to control when the rotating device rises, when the first material shifting mechanism and the double-rod material shifting mechanism descend to shift materials, and the descending height.

[0032] Furthermore, an adsorption head is provided at the center of the rotating disk, an adsorption tube is provided at the center of the rotating tube, all the adsorption tubes are connected to a common negative pressure adsorption machine, and the adsorption tubes are connected to the adsorption head.

[0033] By setting the adsorption head, negative pressure can be formed at the bottom of the egg tart cup to ensure that the egg tart cup can rotate with the rotating ring to avoid losing steps.

[0034] Furthermore, the pre-punching device includes a punching frame and a lifting frame, the punching heads are evenly distributed on the punching frame in a rectangular shape, the lifting frame is arranged on the lower side of the bearing plate, and the lifting frame is evenly distributed with supporting heads in a rectangular shape, and the supporting heads correspond to the punching heads one by one;

[0035] A lifting device is provided on both sides of the stamping frame and the lifting frame, and the lifting device includes a height plate, an upper motor screw module arranged on the top of the height plate, and a lower motor screw module arranged at the bottom of the height plate. The bottom of the upper motor screw module is connected to the stamping frame, and the top of the lower motor screw module is connected to the lifting frame.

[0036] Through the cooperation of the stamping frame and the lifting frame, multiple stamping heads can work simultaneously, effectively improving the working efficiency of the pre-stamping device. At the same time, the lifting frame and the supporting head can ensure that the stamping head can press the dough firmly against the bottom of the egg tart cup. Without the supporting head, the dough may not adhere firmly to the bottom of the egg tart cup, resulting in the movement of the dough during subsequent material feeding.

[0037] Further, the conveying device includes two chain conveying mechanisms arranged symmetrically. The chain drive mechanism includes a driving sprocket, a driven sprocket, and a conveyor chain connecting the driving sprocket and the driven sprocket. There are drive rods connecting between the two driving sprockets and between the two driven sprockets. The driving sprocket is connected to a conveying motor, and both ends of the bearing plate are installed on two conveyor chains.

[0038] Using two chain conveying mechanisms to form the conveying device can provide installation space for the rotating device arranged on the lower side of the bearing plate, effectively improving the space utilization rate of the production line.

[0039] Further, connecting blocks are evenly distributed on the conveyor chain. A limiting block is provided at the top of the connecting block, and a limiting hole is provided at the top of the bearing plate. The limiting block is snapped into the limiting hole;

[0040] A frame is provided outside the conveying device. The chain conveying mechanisms are all installed on the frame. The frame is provided with side edges at the bottom and both sides close to the two conveyor chains.

[0041] Through the cooperation of the limiting block and the limiting hole, the bearing plate can be lifted by devices such as the supporting head and the rotating device, facilitating the work of the pre-stamping device, the first material feeding device, and all double-rod material feeding devices.

[0042] Further, a moving device is also provided at one end of the conveying device close to the double-rod material feeding device;

[0043] The moving device includes an ejecting mechanism arranged on the lower side of the bearing plate and a grasping and moving structure arranged on the upper side of the conveying device. The ejecting mechanism is evenly distributed with ejecting heads in a rectangular shape. The grasping and moving structure is provided with a number of moving positions, and the moving positions correspond to the ejecting heads one by one. The number of processing positions in a row is the same as the number of moving positions in a row.

[0044] By setting the moving device, the conveying of subsequent processes can be effectively disconnected from the conveying device of the present application, so that the conveying device of the present application only needs to cooperate with the pre-stamping device, the first material feeding device, and all double-rod material feeding devices of the present application.

[0045] Further, one end of the conveying device close to the pre-stamping device is connected to a feeding production line, and the feeding production line includes:

[0046] Egg tart cup storage device: It includes storage positions evenly distributed in a rectangle, and egg tart cups are stacked vertically on each of the storage positions;

[0047] Flip feeding device: It includes a robotic arm mechanism and adsorption vacuum heads evenly distributed in a rectangle. A grasping plate is provided at the top of the robotic arm, and the adsorption vacuum heads are all arranged on the grasping plate, and the adsorption vacuum heads correspond to the storage positions one by one;

[0048] Conveyor device: A conveyor device connecting the flip feeding device and the tart shell production line;

[0049] Tart stick cutting device: It includes a tart stick conveyor belt mechanism and an ultrasonic cutting knife device arranged on the tart stick conveyor belt mechanism. A tart stick storage position is provided on one side of the tart stick conveyor belt mechanism where the ultrasonic cutting knife device is located, and the number of the tart stick storage positions corresponds to the number of a row of storage positions;

[0050] Height difference conveyor belt: It is arranged at one end of the tart stick conveyor belt mechanism close to the ultrasonic cutting knife device, and the upper surface of the height difference conveyor belt at the end close to the tart stick conveyor belt mechanism is lower than the upper surface of the tart stick conveyor belt mechanism. A grasping device is provided at the other end of the height difference conveyor belt. The grasping device is evenly distributed with grasping heads in a rectangle, and the number of a row of the grasping heads corresponds to the number of a row of storage positions;

[0051] The height difference conveyor belt and the tart stick cutting device are arranged on the conveyor device and are located between the flip feeding device and the conveyor device of the tart shell production line.

[0052] The technical principle of the present invention is: Manually stack the egg tart cups in the storage positions, and then the flip feeding device sucks the egg tart cups through the vacuum adsorption heads and moves them to the conveyor device by the robotic arm mechanism. At the same time, the tart stick cutting device conveys the tart sticks placed on the tart stick conveyor belt mechanism to the ultrasonic cutting knife device and cuts them into thin cylindrical blocks. Then, when reaching the height difference conveyor belt, due to the height difference, they will become lying flat states, and finally reach the grasping device and are grasped by the grasping heads into the egg tart cups on the conveyor device, and finally conveyed to the pre-stamping device.

[0053] Compared with the prior art, the present invention has the following beneficial effects: Through the feeding production line cooperating with the tart shell production line, the full-automatic production of tart shells from tart sticks is realized. The steps that require manual labor are only to place the egg tart cups into the storage positions and place the tart sticks on the tart stick storage positions, effectively improving the automation degree of tart shell production.

[0054] Furthermore, there are two egg tart cup storage devices, and a rotating plate is provided under the two egg tart cup storage devices. A rotating motor is connected to the center of the rotating plate.

[0055] Setting two egg tart cup storage devices can achieve the combination of manual placement of egg tart cups and automatic feeding without interference, effectively improving the work efficiency.

[0056] Further, more than one set of conveyor belts with height differences and a tower stick cutting device are provided on the conveying device.

[0057] By setting multiple sets of conveyor belts with height differences and a tower stick cutting device, the efficiency of placing the dough into the egg tart cups is effectively improved, that is, the feeding efficiency is improved.

[0058] Further, a moving device is provided between the conveying device of the feeding production line and the conveying device of the tart shell production line;

[0059] The moving device includes two ejecting mechanisms and a grasping and moving structure. The two ejecting mechanisms are respectively arranged on the lower sides of the bearing plates of the two conveying devices. Half of the moving device is arranged on the upper side of the conveying device of the feeding production line, and the other half of the moving device is arranged on the upper side of the conveying device of the tart shell production line.

[0060] By setting the moving device, the conveying devices of the feeding production line and the tart shell production line are two, so that the two conveying devices only need to cooperate with their respective production equipment, reducing the control complexity of the two conveying devices.

[0061] A tart shell production method of a tart shell production line according to an embodiment of the present invention includes:

[0062] S1. Pre-pressing: The conveying device conveys the egg tart cups with dough to the pre-stamping device, and the pre-stamping device presses the dough against the bottom of the egg tart cup so that the dough closely adheres to the bottom of the egg tart cup;

[0063] S2. First feeding: The conveying device conveys the egg tart cups that have completed step S1 to the first feeding device. The first feeding device presses a pit in the center of the dough in the tart shell with a feeding head. The pit is the deepest depth of the tart shell, and then the feeding head moves left and right. At the same time, the rotating device of the first feeding device drives the egg tart cup to rotate to complete the first feeding;

[0064] S3. Two-time feeding: The conveying device conveys the egg tart cups that have completed step S2 to the double-rod feeding device. The rotating device of the double-rod feeding device drives the egg tart cup to rotate, and the two feeding heads of the double-rod feeding device make reciprocating motions of moving away from and approaching each other at the center of the tart shell;

[0065] Step S3 is performed at least twice, and the height and stroke of the reciprocating motion of the two feeding heads are different each time, and are shallower and shallower in sequence according to time, and the stroke is larger and larger in sequence according to time. The height of the first reciprocating motion is higher than the height of the feeding head of the first feeding device;

[0066] S4. Discharging: The conveying device conveys the tart shells that have completed the last step S3 to the next process.

[0067] Through at least two S3 steps, with the depth gradually decreasing and the stroke gradually increasing each time, the egg tart dough can be directly shaped into the required egg tart crust shape without the need for forming processing. In the pre-pressing step, the dough is only pressed tightly at the bottom of the egg tart cup, ensuring the firmness of the connection between the dough and the bottom of the egg tart cup, and preventing the dough from clinging to the side wall of the egg tart cup. In this way, while ensuring that the dough does not move during the feeding process, the crispness of the edge of the egg tart crust can be maximally guaranteed. The dough clinging to the side wall of the egg tart cup is gradually formed in the S2 and S3 steps.

[0068] Further, before the S1 step, the following steps are also included:

[0069] a. Material storage: Stack the empty egg tart cups on the storage positions of the egg tart cup storage device in sequence;

[0070] b1. Loading: The flipping loading device controls its robotic arm mechanism to make the adsorption vacuum head approach the egg tart cup storage device, adsorb the top layer of egg tart cups on the adsorption vacuum head, and then move to the conveyor device;

[0071] b2. Dough cutting: Place the tartlet rods on the tartlet rod conveyor mechanism, and cut them into sheet-like dough by the ultrasonic cutter device. Then, the dough is conveyed to the height difference conveyor by the tartlet rod conveyor mechanism. Since the height difference conveyor is lower than the tartlet rod conveyor mechanism, the dough will change from a vertical state to a flat state here;

[0072] c. Dough grasping: The dough in step b2 is conveyed to the grasping device, and the grasping mechanism grasps the dough into the egg tart cups on the conveyor device in step b1;

[0073] d. Material transfer: The conveyor device transfers the egg tart cups with dough to the pre-stamping device for the S1 step.

[0074] In step b2, after the dough is changed to a flat state and then grasped into the egg tart cup, it is convenient for the pre-stamping device to stamp the dough, which can ensure that the dough is not overly compacted due to its shape.

[0075] Preferably, through steps a - d, the automatic feeding of the egg tart cups and the dough is realized. Brief Description of the Drawings

[0102] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0103] As Figure 1 shown in the tart shell production method of the tart shell production line, including:

[0104] a. Storage: Stack the empty egg tart cups on the storage positions of the egg tart cup storage device 71 in sequence.

[0105] Specifically, in this step, there are two egg tart cup storage devices 71. After one egg tart cup storage device 71 is filled with egg tart cups, rotate it 180° and then place the egg tart cups on the other egg tart cup storage device 71. At the same time, step b1 can be carried out.

[0106] b1. Feeding: The flipping feeding device 72 controls its robotic arm mechanism 721 to make the adsorption vacuum head 723 approach the egg tart cup storage device 71, adsorb the top layer of egg tart cups on the adsorption vacuum head 723, and then move to the conveyor device 4 to complete the feeding of the empty egg tart cups.

[0107] b2. Cutting the material: Place the tart sticks on the tart stick conveyor mechanism 81, cut them into sheet-like dough by the ultrasonic cutter device 82, and then convey them to the height difference conveyor 9 by the tart stick conveyor mechanism 81. Since the height difference conveyor 9 is lower than the tart stick conveyor mechanism 81, the dough will change from a vertical state to a flat state here, that is, the process from tart sticks to dough is completed. Specifically, steps b2 and a and b1 are synchronized and there is no sequence.

[0108] c. Grabbing the material: The dough in step b2 will be conveyed to the grabbing device 91, and the grabbing mechanism grabs the dough into the egg tart cups on the conveyor device 4 in step b1 to complete the combination of the dough and the empty egg tart cups.

[0109] d. Shifting the material: The conveyor device 4 conveys the egg tart cups with dough to the conveyor device 4 on the tart shell production line.

[0110] S1. Pre-pressing: The conveyor device 4 conveys the egg tart cups with dough to the pre-stamping device 1, and the pre-stamping device 1 presses the dough against the bottom of the egg tart cup, making the dough closely adhere to the bottom of the egg tart cup. Here, mainly to make the dough tightly pressed against the bottom of the egg tart cup to prevent the dough from shifting during subsequent material shifting.

[0111] S2. First material shifting: The conveyor device 4 conveys the egg tart cups that have completed step S1 to the first material shifting device 2. The first material shifting device 2 uses the material shifting head 311 to press a concave pit in the center of the dough in the egg tart shell. The concave pit is the deepest depth of the egg tart shell, and then the material shifting head 311 moves left and right. At the same time, the rotating device 6 of the first material shifting device 2 drives the egg tart cup to rotate to complete the first material shifting. The first material shifting is carried out by one material shifting head 311. One material shifting head 311 can quickly make the dough approach the shape of the egg tart shell and improve production efficiency.

[0112] S3. Two - time material feeding: The conveying device 4 conveys the egg tart cups that have completed step S2 to the double - rod material - feeding device 3. The rotating device 6 of the double - rod material - feeding device 3 drives the egg tart cups to rotate. The two material - feeding heads 311 of the double - rod material - feeding device 3 make reciprocating motions of moving away from and approaching each other at the center of the egg tart crust. Through the reciprocating motions of the two material - feeding heads 311 moving away from and approaching each other, a fine material - feeding motion is carried out. Because of its symmetry, the egg tart crust can be directly fed into the required shape of the egg tart crust without the need for later stamping and shaping.

[0113] Specifically, step S3 is carried out at least twice. In the embodiment, the method of three - time material feeding is adopted. Moreover, the height and stroke of the reciprocating motion of the two material - feeding heads 311 are different each time, and they become shallower in sequence according to time, and the stroke becomes larger in sequence according to time. The height of the first reciprocating motion is higher than the height of the material - feeding head 311 of the first material - feeding device 2. This method can directly produce the egg tart crust into the required shape. In essence, it is achieved through the specific shape of the material - feeding head 311 and the designed material - feeding stroke. Among them, the optimal one is to adopt the material - feeding method of horizontal movement because its moving distance is easy to control, and thus the final forming effect of the egg tart crust can be effectively guaranteed.

[0114] S4. Discharging: The conveying device 4 conveys the egg tart crust that has completed the last step S3 to the next process.

[0115] For the above - mentioned egg tart crust production method of the egg tart crust production line, after trial operation, when producing 1000 egg tart crusts, none of them have unqualified shapes.

[0124] As Figure 3 shown, the pre-stamping device 1 includes a stamping frame 11 and a lifting frame 12. Among them, the stamping heads 111 are evenly distributed in a rectangle on the stamping frame 11. The lifting frame 12 is arranged on the lower side of the bearing plate 41. The lifting frame 12 is evenly distributed with support heads 121 in a rectangle. The support heads 121 correspond to the stamping heads 111 one by one. Lifting devices 5 are provided on both sides of the stamping frame 11 and the lifting frame 12. While driving the stamping heads 111 to move downward, they can drive the support heads 121 to move up and down to support the egg tart cups.

The movable rods 31 can move along the length direction of the support frame 21. One end of all the movable rods 31 is connected with a transmission plate 32, and the transmission plate 32 is connected with the screw mechanism 222; a row of blanking heads 311 is installed on the same movable rod 31. Furthermore, all the blanking heads 311 can be controlled to move by one movable rod 31, and all the movable rods 31 can be controlled to move by one screw mechanism 222.

[0126] In this embodiment, it is a horizontal movement mode, which can realize the precise control of the blanking heads 311 through the above simple structure and realize the batch production of egg tart crusts.

[0127] As shown Figure 5 in the figure, the double-rod feeding mechanism includes a support frame 21 and two moving mechanisms 22 symmetrically arranged on the support frame 21; among them, the moving mechanism 22 includes a driving motor 221 and a screw mechanism 222 connected to the driving motor 221, and the two driving motors 221 and the screw mechanism 222 are respectively installed at both ends of the support frame 21; a set of movable rods is evenly distributed along the width direction of the support frame 21, and each set of movable rods includes two movable rods 31 arranged in parallel. The movable rod 31 can move along the length direction of the support frame 21. One end of one movable rod 31 in all sets of movable rods is connected to a transmission plate 32, and the other end of the other movable rod 31 in all sets of movable rods is also connected to a transmission plate 32. The two transmission plates 32 are respectively connected to the screw mechanisms 222 of the two moving mechanisms 22; two feeding heads 311 of a row of feeding head groups are respectively installed on the two movable rods 31 of a set of movable rods, and the two feeding heads 311 are installed on the side where the two movable rods 31 are close to each other. Furthermore, the two movable rods 31 can support each other, making the movement of the two feeding heads 311 more stable.

[0128] The double-rod feeding mechanism in this application can replace the first feeding mechanism and the rotating device 6 to form the first feeding device 2, that is, the double-rod feeding device 3 can replace the first feeding device 2 to complete the first feeding step of S2. However, because the structure of the first feeding device 2 is simpler than that of the double-rod feeding device 3, it helps to reduce the cost of the entire production line.

[0129] As shown Figures 6 - 8 in the figure, all the rotating devices 6 of the first feeding device 2 or the double-rod feeding device 3 are provided with a shared lifting frame 64. A rotating motor 641 is provided on the lifting frame 64, and the rotating motor 641 is drivingly connected to at least one row of rotating devices 6.

[0130] Specifically, the rotating device 6 includes a rotating tube 61, a rotating disk 62 provided at the top of the rotating tube 61, and a driving gear 63 provided at the bottom of the rotating tube 61. The driving gear 63 is drivingly connected to the rotating motor 641 by belt transmission, and the driving connection method therein can be a transmission method of sequential gear meshing; a bearing seat 611 is provided on the rotating tube 61, and the bearing seat 611 is installed on the lifting frame 64 to realize the installation of the rotating tube 61. Each rotating disk 62 is aligned with a processing position 401. An installation hole 411 is provided at the corresponding processing position 401 of the bearing plate 41. A rotating ring 412 is provided in the installation hole 411, and the bottom of the rotating ring 412 is connected to the rotating disk 62, so that the rotating disk 62 can drive the rotating ring 412 to rotate, and thus the egg tart cups placed on the rotating ring 412 also rotate accordingly.

[0131] Specifically, the rotating ring 412 is provided with stripes, and conical blocks 621 are circumferentially and evenly distributed on the inner side of the rotating disk 62. A spring is provided between the conical blocks 621 and the rotating disk 62, so as to ensure that the conical blocks 621 can abut against the stripes.

[0132] As Figure 8 shown, an adsorption head 65 is provided at the center of the rotating disk 62, and an adsorption tube 651 is provided at the center of the rotating tube 61. Of course, the hollow structure of the rotating tube 61 can also be used to replace the adsorption tube 651. All the adsorption tubes 651 are connected to a common negative pressure adsorption machine, and the adsorption tube 651 communicates with the adsorption head 65, which can give an adsorption force to the bottom of the egg tart cup to ensure that the egg tart cup can rotate with the rotating ring 412.

[0133] As Figures 2 - 6 shown in FIGS. 8 and 9, lifting devices 5 are provided on both sides of the lifting frame 64 and the support frame 21. The lifting device 5 includes a height plate 51, an upper motor screw module 52 provided at the top of the height plate 51, and a lower motor screw module 53 provided at the bottom of the height plate 51. The bottom of the upper motor screw module 52 is connected to the support frame 21, and the top of the lower motor screw module 53 is connected to the lifting frame 64. In the lifting devices 5 of the stamping frame 11 and the lifting frame 12, the bottom of the upper motor screw module 52 is connected to the stamping frame 11, and the top of the lower motor screw module 53 is connected to the lifting frame 12, that is, the same lifting structure is adopted, which helps to control the vertical height of the pre-stamping device 1, the first material feeding device 2 and the double-rod material feeding device 3 through the control system. Of course, the pre-stamping device 1, the first material feeding device 2 and the double-rod material feeding device 3 can also be provided with separate lifting structures for lifting during work, while the lifting device 55 is only used to control the overall height.

[0134] As Figures 10 - 12 shown, the conveying device 4 includes two symmetrically arranged chain conveying mechanisms 42. The chain transmission mechanism includes a driving sprocket 421, a driven sprocket 422, and a transmission chain 423 connecting the driving sprocket 421 and the driven sprocket 422. Transmission rods 424 are provided between the two driving sprockets 421 and between the two driven sprockets 422. The driving sprocket 421 is connected to a conveying motor 425. Through the above structure, it is convenient to install structures such as the support head 121 and the rotating device 6 between the two transmission chains 423.

[0135] Specifically, connecting blocks 43 are symmetrically installed on the two transmission chains 423, and both ends of the bearing plate 41 are respectively connected to the two transmission chains 423 through the connecting blocks 43, so that the transmission chain can drive the bearing plate 41 to move.

[0136] As Figure 2 、 11As shown in FIG. -12, a limiting block 431 is provided on the connecting block 43, and limiting holes 413 are provided at both ends of the bearing plate 41. The limiting blocks 431 are inserted into the limiting holes 413 at both ends, and the bearing plate 41 can move along the height direction of the limiting block 431, facilitating the support head 121 and the rotating device 6 to jack up.

[0137] As Figure 12 shown, two connecting pieces 432 are provided at the bottom of the connecting block 43, and two connecting holes 4321 are provided on each connecting piece 432. The connecting block 43 is connected to two adjacent pin shafts of the conveyor chain 423 through the two connecting holes 4321, ensuring that the connecting block 43 can move along with the conveyor chain 423.

[0138] As Figures 10 - 11 shown, the outside of the conveying device 4 is supported by a frame 44, and the chain conveying mechanism 42 is installed on the frame 44. The frame 44 is fixed with edge guards at the bottom and both sides near the outside of the two conveyor chains 423. The edge guards block the bearing plate 41 at the bottom and both sides, preventing the bearing plate 41 from detaching from the limiting block 431. Specifically, the edge guards on both sides are arc-shaped edge guards 441, and the edge guard at the bottom is a straight edge guard 442. The distance between the arc-shaped edge guard 441 and the transmission chain is greater than the distance between the straight edge guard 442 and the transmission chain, because the bearing plate 41 requires more space to pass when moving along the driving sprocket 421 and the driven sprocket 422, so a larger distance needs to be set.

[0139] As Figures 11 - 12 shown, a support bar 443 is installed at the top position of the frame 44 near the inside of the two conveyor chains 423. When the conveyor chain 423 is at the top position, it is closely attached to the support bar 443. Specifically, a groove 4431 is provided at the top of the support bar 443, and the conveyor chain 423 is stuck in the groove 4431 to ensure the stable conveying direction of the conveyor chain 423.

[0140] As Figure 13 shown, a tensioning mechanism 45 is provided at both sides of the frame 44 near the two driven sprockets 422. Specifically, the tensioning mechanism 45 includes a movable frame 451, a spiral frame 452, and a spiral rod 453. A chute 444 is provided on the frame 44, the movable frame 451 is installed on the chute 444, the driven sprocket 422 is installed on the movable frame 451, the spiral frame 452 is installed on the frame 44, the spiral rod 453 is connected to the driven sprocket 422 by a bearing structure, and the spiral rod 453 is threadedly connected to the spiral frame 452. Only by rotating the spiral rod 453 can the driven sprocket 422 and the movable frame 451 be driven to move along the chute 444, realizing the adjustment of the tension of the conveyor chain 423.

[0141] When the above-mentioned conveying device 4 is in operation, the bearing plate 41 is used to carry the egg tart cups, the transmission chain is used to drive the bearing plate 41, the support bar 443 is used to support the bearing plate 41, and the limiting hole 413 and the limiting block 431 enable the bearing plate 41 to be lifted by structures such as the support head 121 and the rotating device 6. As for the edge, it ensures that the bearing plate 41 does not break away from the limiting block 431 when it rotates, that is, at the two sides and the bottom positions.

[0142] As Figure 14 shown, one end of the conveying device 4 close to the pre-stamping device 1 is connected to a feeding production line, and the feeding production line includes an egg tart cup storage device 71, a flipping feeding device 72, a conveying device 4, a tower stick cutting device 8, and a height difference conveyor belt 9.

[0143] As Figures 15 - 16 shown, the egg tart cup feeding device includes the above-mentioned egg tart cup storage device 71 and a flipping feeding device 72 provided on one side of the top of the egg tart cup storage device 71. Specifically, the egg tart cup storage device 71 has uniformly distributed rectangular storage positions, and egg tart cups are vertically stacked on each storage position.

[0144] As Figures 15 - 16 shown, an outer frame 73 is provided outside the egg tart cup storage device 71. There are two egg tart cup storage devices 71. The outer frame 73 can protect the two egg tart cup storage devices 71. A rotating plate 731 is provided under the two egg tart cup storage devices 71. The center of the rotating plate 731 is connected to a rotating motor 732. The rotating plate 731 can be driven by the rotating motor 732 to rotate, driving the egg tart cup storage devices 71 thereon to exchange positions. The egg tart cup storage device 71 close to the flipping feeding device 72 is used for feeding, and the other egg tart cup storage device 71 is convenient for manual placement of egg tart cups.

[0145] As Figures 15 - 17 shown, the flipping feeding device 72 includes robotic arm mechanisms 721 symmetrically arranged on both sides of the outer frame 73 and uniformly distributed rectangular adsorption vacuum heads 723. Gripping plates 722 are provided at the tops of the two robotic arm mechanisms 721, and the adsorption vacuum heads 723 are all arranged on the gripping plates 722, and the adsorption vacuum heads 723 correspond to the storage positions one by one.

[0146] Specifically, a flipping device is fixed on one side of the outer frame 73. The bottoms of the two robotic arm mechanisms 721 are drivingly connected to the flipping device. A synchronous driving mechanism 725 is provided on the robotic arm mechanisms 721. The synchronous driving mechanism 725 is drivingly connected to the flipping device and the gripping plates 722. The flipping device can drive the gripping plates 722 and the robotic arm mechanisms 721 to rotate synchronously.

[0147] As Figure 17As shown in the figure, the flipping device includes a flipping motor 724 and a transmission rod 424 connected to the flipping motor 724. The transmission rod 424 is drivingly connected to the bottoms of two robotic arm mechanisms 721, so that the two robotic arm mechanisms 721 can rotate synchronously.

[0148] As Figure 17 shown in the figure, the synchronous drive mechanism 725 includes a driving pulley 7251, a driven pulley 7252, and a synchronous belt 7253 connecting the driving pulley 7251 and the driven pulley 7252. The driving pulley 7251 is installed on the transmission rod 424, and the driven pulley 7252 is installed on the top of the robotic arm mechanism 721. A synchronous rod 7254 is connected to the driven pulley 7252. The synchronous rod 7254 is respectively connected to the tops of the two robotic arm mechanisms 721 by bearings. The synchronous rod 7254 is connected to the grasping plate 722, so that the synchronous rod 7254 will drive the grasping plate 722 to rotate synchronously with the transmission rod 424, so that no matter what the rotation angle of the robotic arm mechanism 721 is, the grasping plate 722 always faces the bottom, that is, it is parallel to the egg tart cup storage device 71.

[0149] Specifically, a tension pulley 7255 is also provided between the driving pulley 7251 and the driven pulley 7252. The tension pulley 7255 is closely attached to the outer surface of the synchronous belt 7253. The tension pulley 7255 is installed on the robotic arm mechanism 721 and is used to tension the synchronous belt 7253.

[0150] As Figure 18 shown in the figure, the middle part of the synchronous rod 7254 is a hollow structure. An adsorption vacuum tube 7231 is provided in the synchronous rod 7254. The adsorption vacuum tube 7231 is connected to all adsorption vacuum heads 723. The adsorption vacuum tube 7231 passes through one end of the synchronous rod 7254 and is connected to a vacuum adsorption machine. Of course, the hollow structure of the synchronous rod 7254 can also be used to replace part of the adsorption vacuum tube 7231. By giving the adsorption vacuum heads 723 an adsorption force through the vacuum adsorption machine, the egg tart cups can be sucked.

[0151] As Figure 16 shown in the figure, the egg tart cup storage device 71 includes a bottom plate 711 and several groups of egg tart cup fixing rods 712 evenly distributed on the bottom plate 711. Each group of egg tart cup fixing rods 712 corresponds to a storage position. A feeding plate 713 is provided on the bottom plate 711. A through hole 7131 is provided on the feeding plate 713. The egg tart cup fixing rods 712 pass through the through hole 7131. Specifically, pushing mechanisms 714 are provided on both sides of the bottom of the feeding plate 713. After an egg tart cup is taken away, the feeding plate 713 will be pushed upward by the pushing mechanisms 714 by the distance of one egg tart cup.

[0152] As Figure 16As shown, there are four fixed rods 712 for each group of egg tart cups, which can ensure that the egg tart cups are restricted between the fixed rods 712 of the egg tart cups. The top of the fixed rod of the egg tart is provided with a discharge baffle 715, and a discharge port 716 is provided at the corresponding storage position of the discharge baffle 715. Specifically, one end of the discharge port 716 extends to the edge of the discharge baffle 715, so that the adsorption vacuum head 723 can pull out the egg tart cup from the discharge port 716.

[0153] As Figures 14 - 15 shown, one end of the outer frame 73 close to the robotic arm mechanism 721 is connected with a conveyor device 4. The conveyor device 4 here is connected to the conveyor device 4 of the tart shell production line, and the structures of the two are the same.

[0154] As Figure 19 shown, the tart stick cutting device 8 includes a tart stick conveyor belt mechanism 81 and an ultrasonic cutting knife device 82 arranged on the tart stick conveyor belt mechanism 81. A tart stick storage position 811 is provided on one side of the tart stick conveyor belt mechanism 81 where the ultrasonic cutting knife device 82 is located. The number of the tart stick storage positions 811 corresponds to the number of a row of storage positions, and a row of tart sticks can be synchronously cut into dough by the ultrasonic cutting knife device 82.

[0155] As Figures 19 - 20 shown, the height difference conveyor belt 9 is arranged at one end of the tart stick conveyor belt mechanism 81 close to the ultrasonic cutting knife device 82, and the upper surface of the end of the height difference conveyor belt 9 close to the tart stick conveyor belt mechanism 81 is lower than the upper surface of the tart stick conveyor belt mechanism 81. A grasping device 91 is provided at the other end of the height difference conveyor belt 9. The grasping heads 913 are evenly distributed in a rectangle on the grasping device 91. The grasping heads 913 can adopt a suction cup structure, and the number of a row of grasping heads 913 corresponds to the number of a row of storage positions.

[0156] As Figure 14 shown, the height difference conveyor belt 9 and the tart stick cutting device 8 are arranged on the conveyor device 4 and are located between the flipping feeding device 72 and the conveyor device 4 of the tart shell production line. In this embodiment, 2 groups are set.

[0157] As Figure 14 、 20 shown, the grasping device 91 includes an X-axis transmission mechanism 911, a Z-axis transmission mechanism 912 and a plate for fixing the grasping heads 913. The plate for fixing the grasping heads 913 is installed on the Z-axis transmission mechanism 912, and the Z-axis transmission mechanism 912 is installed on the X-axis transmission mechanism 911, so as to grasp the dough, lift it, then move it, and finally lower it onto the conveyor device 4 to place the dough in the empty egg tart cups.

[0158] As Figure 14 shown, more than one group of height difference conveyor belts 9 and tart stick cutting devices 8 are provided on the conveyor device 4 to improve the feeding efficiency.

[0159] In this embodiment, both the two material feeding steps in the production method of the tart crust are completed by the same double-rod material feeding device 3.

[0160] Embodiment 2

[0161] As Figure 21 shown, the difference between this embodiment and Embodiment 1 is that three double-rod material feeding devices 3 are provided, and the two material feeding steps of S3 are completed by the three double-rod material feeding devices 3. Compared with Embodiment 1, its production efficiency is improved, but the cost of its production line will increase.

[0162] Embodiment 3

[0163] As Figures 22 - 25 shown, the difference between this embodiment and Embodiments 1-2 is that a moving device 46 is provided between the conveying device 4 of the feeding production line and the conveying device 4 of the tart crust production line.

[0164] Specifically, the moving device 46 includes two ejecting mechanisms 461 and a grasping and moving structure 462. The two ejecting mechanisms 461 are respectively arranged on the lower sides of the bearing plates 41 of the two conveying devices 4. Half of the moving device 46 is arranged on the upper side of the conveying device 4 of the feeding production line, and the other half of the moving device 46 is arranged on the upper side of the conveying device 4 of the tart crust production line. The ejecting heads 4613 are evenly distributed in a rectangle on the ejecting mechanism 461. The grasping and moving structure 462 is provided with a number of moving positions, and the moving positions correspond to the ejecting heads 4613 one by one. The number of a row of processing positions 401 is the same as the number of a row of moving positions.

[0165] A moving device 46 is also provided at one end of the conveying device 4 of the tart crust production line close to the double-rod material feeding device 3, and the structural components of this moving device 46 are the same as those of the above-mentioned moving device 46. The subsequent moving equipment can adopt a conventional conveyor belt to directly convey the egg tart crust away without using the ejecting mechanism 461.

[0166] As Figure 25 shown, the ejecting mechanism 461 includes a base 4611 and a lifting mechanism 4612 for pushing the base 4611 to rise. The ejecting heads 4613 are evenly distributed on the base 4611. A suction cup is provided at the center of the ejecting head 4613, and the suction cup is connected to a negative pressure adsorption machine to ensure that the suction cup can adsorb the egg tart cup.

[0167] As Figure 24As shown, the grasping and moving structure 462 includes two driving belt mechanisms 4621 and a mounting plate 4622 mounted between the two driving belt mechanisms 4621. That is, a protrusion is provided in the middle of the mounting plate 4622 and fixed to the driving belt of the driving belt mechanism 4621. Rod members 4623 are evenly distributed under the mounting plate 4622, and a plate member 4624 is fixed under the rod members 4623. A gap is left between two adjacent plate members 4624 for placing egg tart cups. The length direction of the plate member 4624 is parallel to the moving direction of the driving belt mechanism 4621, and the gap between the two plate members 4624 forms a row of moving positions.

[0168] During use, the lifting mechanism 4612 drives the ejecting head 4613 to lift the egg tart cups, and then the driving belt mechanism 4621 drives the plate member 4624 to move towards one side of the egg tart cups, just clamping all the egg tart cups. Then the lifting mechanism 4612 drives the ejecting head 4613 to descend, and then the driving belt mechanism 4621 drives the plate member 4624 and the egg tart cups thereon to move to the other side. After the movement is completed, the lifting mechanism 4612 of another ejecting mechanism 461 drives the ejecting head 4613 to move upward, so that the suction cup adsorbs the egg tart cups. Then the driving belt mechanism 4621 drives the plate member 4624 to move to the other side again, so that the egg tart cups are separated from the plate member 4624. Finally, the lifting mechanism 4612 drives the ejecting head 4613 to descend, so that the egg tart cups are moved to the subsequent moving device or the conveying device 4 of the tart shell production line.

[0169] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
