Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a product packaging device. Background Technology

[0002] Currently, various dumpling wrapping equipment has emerged in the industry, such as the "Automatic Dumpling Machine" with publication number CN201120387278.0. This equipment integrates a frame, dough-making mechanism, feeding mechanism, wrapping mechanism, pushing mechanism, conveying mechanism, rotating worktable, forming mechanism, and transmission mechanism. The dough-making mechanism automatically prepares dumpling wrappers, the feeding mechanism precisely delivers filling, the wrapping mechanism completes the initial wrapping of dumpling wrappers and filling, and then, through the coordinated operation of the pushing mechanism, conveying mechanism, and rotating worktable, the forming mechanism finally completes the shaping of the dumplings. This improves dumpling production efficiency, reduces labor costs, and ensures the hygiene, safety, and uniformity of dumpling appearance through standardized mechanical movements. It has become an important piece of equipment for food processing enterprises to achieve large-scale production and is widely used in restaurant chains, food processing plants, and other scenarios.

[0003] However, existing automatic dumpling machines still have the following defects in actual production and maintenance. In automatic dumpling machines, the support plate is connected to the mounting base of the forming mechanism by multiple hexagonal bolts or countersunk head bolts evenly distributed along the edge or bottom of the support plate and penetrating the support plate. Some machines also use locating pins to circumferentially limit the support plate on the basis of bolt connection. The locating pins need to be embedded in the corresponding pin holes opened in the support plate and the mounting base, forming a double fixing structure of "bolt fastening + locating pin limit". Although it improves the installation accuracy, it makes the disassembly and assembly of the support plate extremely inconvenient. During long-term operation of the equipment, the support plate is prone to wear and deformation due to frequent contact with dumpling skins and bearing the pressure of the blank. It needs to be disassembled and replaced regularly to ensure the quality of dumpling forming. However, under the existing connection structure, operators need to use special tools to perform complicated disassembly operations, which is time-consuming and laborious. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a product wrapping device, including a forming mechanism, which includes: A fixing plate, which is fixedly installed on the turntable; A hollow mold base, which is fixedly mounted on a fixed plate; The skin support mechanism includes a skin support plate disposed on the top of the hollow mold base. The skin support mechanism has a skin support cavity corresponding to the position of the hollow mold base, and a hole matching the hollow mold base is opened in the skin support cavity. The skin support plate is fixedly installed on the mounting block by a connecting structure. A connecting rod is provided on the surface of the mounting block for mounting the support plate. The connecting rod has a frustum portion, and a step is formed at the connection between the frustum portion and the main body of the connecting rod. The connection structure includes: A housing, which is fixed to the lower surface of a support plate, has a slot corresponding to a connecting rod. A knob, which is rotated and mounted on the outside of the housing; A rotating block, which is rotatably mounted inside the housing and connected to the knob, has a notch on its periphery; An active plate is rotatably mounted inside the box, with one end positioned within a notch. When the rotating block rotates, it drives the active plate to rotate. The driven plate is rotatably installed inside the box. The driven plate is connected to the driving plate by a spring. An arc-shaped groove is provided on the driven plate at the slot position. The width of the arc-shaped groove is greater than the diameter of the connecting rod body and less than the diameter of the step.

[0005] This invention uses a rotating knob to drive a connected rotating block to rotate synchronously. The notch pushes the active plate to rotate, and the active plate, in turn, drives the driven plate to rotate via a spring. This causes the arc-shaped groove on the driven plate to disengage from or engage with the step of the connecting rod. The entire process eliminates the need to disassemble bolts and remove locating pins one by one, reducing the time spent replacing the support plate.

[0006] Furthermore, the forming mechanism also includes an ejector mechanism, which includes: Top plate, which is slidably disposed within the hollow mold base; A top material rod, one end of which is connected to a top material plate, and the top material rod is slidably engaged with a fixed plate.

[0007] Once the dumplings are shaped, the external cylinder mechanism allows the ejector rod to slide stably along the fixed plate, pushing the ejector plate upward within the hollow mold base. This applies force evenly from the bottom of the dumpling, ejecting it from the dough support cavity. The ejector mechanism, in conjunction with the external cylinder mechanism, enables automatic ejection of the dumplings after they are formed, improving dumpling production efficiency.

[0008] Furthermore, the material feeding mechanism also includes a limiting frame, which is arranged parallel to the fixed plate below it. The material feeding rod is fixedly installed on the limiting frame, and an elastic element is provided between the limiting frame and the fixed plate.

[0009] After the ejector mechanism completes the ejection action, no additional drive components are needed. The elastic element can automatically pull the limit frame towards the fixed plate to reset itself using its own elastic force. This, in turn, causes the ejector rod and ejector plate to fall back to their initial positions within the hollow mold base, achieving automatic and rapid reset of the ejector assembly. During the process of the ejector rod pushing the ejector plate upward to push the dumpling, the elastic element between the limit frame and the fixed plate can buffer the instantaneous impact force generated by the ejection action through its own deformation, reducing damage to the mating surfaces of the ejector plate and the bottom of the dumpling, and the ejector rod and the fixed plate caused by rigid impact.

[0010] Furthermore, the hollow mold base and the support plate maintain relative sliding. The support mechanism also includes a movable plate with a limit groove on one side, which is movably connected to the mounting block by bolts, and rotatably connected to the fixed plate on the other side. A top rod is fixed on the side where the movable plate connects to the fixed plate.

[0011] While the top plate of the top feeding mechanism pushes the dumpling upward to demold, an external force acts on the top rod, driving the movable plate to rotate around the fixed plate, which in turn drives the supporting plate to descend synchronously, so that the dumpling is separated from the supporting cavity. This reduces the pushing resistance of the pushing mechanism, allowing the dumpling to leave the top plate without having to overcome a large resistance under the pushing mechanism of the top plate. This avoids local pulling caused by resistance with the inner wall of the supporting cavity, which could lead to dumpling skin breakage, wrinkling, deformation, or filling squeezing out.

[0012] Furthermore, a roller is installed at the end of the push rod.

[0013] When an external force drives the push rod to rotate the movable plate, the rollers convert the "sliding friction" between the push rod and the mating parts into "rolling friction," which can reduce the wear at the end of the push rod and reduce scratches, dents, and other damage to the surface of the mating parts caused by friction.

[0014] Furthermore, the skin support mechanism also includes a guide rod, which is slidably engaged with the fixed plate, and the skin support plate has an interference fit hole corresponding to the guide rod; An elastic element is provided between the support plate and the fixing plate, and the elastic element is fitted onto the guide rod.

[0015] The guide rod and the fixed plate work together to provide axial guidance and constraint for the lifting and lowering movement of the support plate. After the support plate is driven to descend and complete demolding by external force, the elastic element can automatically push the support plate upward along the guide rod to return to its initial working position by its own elastic force. When the support plate is driven to descend by external force, the elastic element is compressed, absorbing the instantaneous impact force generated by the descent, which can reduce the rigid collision between the support plate and the fixed plate or the bottom of the hollow mold base; when the support plate rises and returns to its original position under the action of the elastic element, the elastic force of the elastic element is slowly released, slowing down the rising speed of the support plate and reducing its impact with the components above. The interference fit between the guide rod and the support plate can fix the guide rod and the support plate without affecting the assembly and disassembly efficiency of the support plate.

[0016] Furthermore, an elastic layer is provided on the inner wall of the socket.

[0017] The elastic layer has a certain deformation capacity, which can adapt to the slight dimensional deviations between the guide rod and the socket, ensuring the tightness of the interference fit, reducing the difficulty of assembly, and minimizing damage to the support plate or guide rod caused by forced assembly.

[0018] This utility model has the following advantages: During installation, the connecting rod is inserted into the slot of the housing. As the connecting rod is inserted, the diameter of the conical part of the connecting rod continuously increases, constantly squeezing the driven plate and forcing it to rotate until the main body of the connecting rod aligns with the slot. Turning the knob then rotates the driven plate, allowing the main body of the connecting rod to enter the slot. The stepped surface and the surface of the driven plate form a limiting position, achieving axial limiting of the support plate. During disassembly and assembly, rotating the knob synchronously rotates the connected rotating block, pushing the driving plate to rotate through the notch. The driving plate then drives the driven plate to rotate via a spring, causing the arc-shaped slot on the driven plate to disengage from or engage with the step of the connecting rod. The entire process eliminates the need to disassemble bolts and remove locating pins one by one, reducing the time spent replacing the support plate. Attached Figure Description

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0022] As described in the background section, in automatic dumpling machines, the support plate is connected to the mounting base of the forming mechanism by multiple hexagonal or countersunk head bolts evenly distributed along the edge or bottom of the support plate and penetrating it. Some machines also use locating pins to circumferentially limit the support plate in addition to the bolt connection. The locating pins need to be embedded in the corresponding pin holes opened on the support plate and the mounting base, forming a double fixing structure of "bolt fastening + locating pin limiting". Although this improves the installation accuracy, it makes the disassembly and assembly of the support plate extremely inconvenient. During long-term operation of the equipment, the support plate is prone to wear and deformation due to frequent contact with dumpling skins and bearing the pressure of the dough. It needs to be disassembled and replaced regularly to ensure the quality of dumpling forming. However, under the existing connection structure, operators need to use special tools to perform complex disassembly operations, which is time-consuming and labor-intensive.

[0023] Example 1: Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a product wrapping device, including a forming mechanism, such as... Figure 1 As shown, the molding mechanism includes: Fixed plate 100, which is fixedly installed on the turntable; Hollow mold base 300, which is fixedly mounted on a fixed plate; Skin care institution 200, such as Figure 2 , 3 As shown, the skin support mechanism includes a skin support plate 210, which is disposed on the top of the hollow mold base. The skin support mechanism has a skin support cavity corresponding to the position of the hollow mold base, and a hole matching the hollow mold base is opened in the skin support cavity. The skin support mechanism is fixedly installed on the mounting block 260 through the connecting structure 270. like Figure 6 As shown, a connecting rod 261 is provided on the surface of the mounting block for mounting the support plate. The connecting rod has a truncated cone portion, and a step is formed at the connection between the truncated cone portion and the main body of the connecting rod. like Figure 4 , 5 As shown, the connection structure includes: Box 271, which is fixed to the lower surface of the support plate, has a slot 271A corresponding to the connecting rod; Knob 275, which is rotated and mounted on the outside of the housing; Rotating block 276, which is rotatably mounted in the housing and connected to the knob, has a notch on its periphery; Active plate 273 is rotatably installed inside the box, with one end set in the notch. When the rotating block rotates, it drives the active plate to rotate. The driven plate 272 is rotatably installed inside the box. The driven plate is connected to the driving plate by a spring. An arc-shaped slot 272A is provided on the driven plate at the slot position. The width of the arc-shaped slot is greater than the diameter of the connecting rod body and less than the diameter of the step.

[0024] In this embodiment, when installing the support plate, hold the support plate 210 and align the slot 271A inside the housing 271 with the connecting rod 261 on the mounting block 260. Slowly push the support plate 210 downwards, allowing the connecting rod 261 to gradually insert into the slot 271A. During insertion, the diameter of the frustum portion of the connecting rod 261 gradually increases with the insertion depth, continuously squeezing the driven plate 272. This forces the driven plate 272 to rotate slightly around its own axis, continuing to push the support plate 210 until the diameter of the main body of the connecting rod 261 is smaller than the frustum portion and moves to the corresponding position of the arc-shaped groove 272A of the driven plate 272. At this time, the operator rotates the knob 275 on the outside of the box 271 clockwise. The knob 275 drives the rotating block 276 connected inside the box to rotate synchronously. The notch on the side of the rotating block 276 pushes the active plate 273 to rotate around its own axis. The active plate 273 pulls the driven plate 272 to rotate through the spring, so that the arc-shaped slot 272A is engaged with the main body of the connecting rod 261. Finally, the stepped surface of the connecting rod 261 fits against the surface of the driven plate 272, forming an axial limit.

[0025] After the equipment is powered on and started, the turntable drives the fixed plate 100, hollow mold base 300, and dumpling wrapper support mechanism 200 to rotate to the initial position and remain stationary. At this time, the dumpling wrapper support cavity of the support plate 210 is directly above the hollow mold base 300, waiting to receive dumpling wrappers and fillings. The wrapper making mechanism transports the pre-made dumpling wrappers to the surface of the support cavity, and the feeding mechanism precisely injects a fixed amount of filling into the dumpling wrapper. When the filling is injected, it squeezes the dumpling wrapper into the hollow mold base, causing it to bend. After the filling is injected, the turntable starts, driving the fixed plate 100, support mechanism 200, and dumpling blank to rotate to the forming position. The pressing component of the forming mechanism presses and shapes the edges of the dumpling.

[0026] When the tray plate 210 becomes worn or deformed, or when it needs to be replaced with a different size tray plate to adapt to different dumpling production, the operator should first stop the equipment and rotate the turntable to a maintenance position that is easy to operate.

[0027] The operator rotates the knob 275 on the outside of the box 271 counterclockwise. The knob 275 drives the rotating block 276 to rotate in the opposite direction. The rotating block 276 drives the active plate 273 to rotate in the opposite direction, pulling the driven plate 272 to rotate, causing the arc-shaped slot 272A to disengage from the main body of the connecting rod 261, thus releasing the axial limit. After the arc-shaped slot 272A is completely disengaged from the connecting rod 261, the operator lifts the support plate 210 upwards, causing the slot 271A of the box 271 to be pulled out from the connecting rod 261, completing the disassembly of the support plate 210. If a new support plate needs to be replaced, the "support plate mechanism installation process" can be repeated, without the need to remove bolts or pull out positioning pins, greatly reducing the replacement time.

[0028] This invention uses a rotating knob to drive a connected rotating block to rotate synchronously. The notch pushes the active plate to rotate, and the active plate, in turn, drives the driven plate to rotate via a spring. This causes the arc-shaped groove on the driven plate to disengage from or engage with the step of the connecting rod. The entire process eliminates the need to disassemble bolts and remove locating pins one by one, reducing the time spent replacing the support plate.

[0029] In addition, this embodiment may also have a positioning hole on the side of the box where the knob is located, and a flange that protrudes outward along the radial direction near the end of the knob. A positioning rod is provided on the flange, and the positioning rod is elastically connected to the flange. When the connecting rod is locked, the top rod, under the action of the elastic element, causes its end to enter the positioning hole to circumferentially constrain the knob.

[0030] In this embodiment, as Figure 1 As shown, the forming mechanism also includes an ejector mechanism 440, as... Figure 7 As shown, the top-feeding mechanism includes: Ejector plate 420, which is slidably disposed within the hollow mold base; The top material rod 430 is connected at one end to the top material plate, and the top material rod is slidably engaged with the fixed plate.

[0031] Once the dumplings are shaped, the external cylinder mechanism allows the ejector rod to slide stably along the fixed plate, pushing the ejector plate upward within the hollow mold base. This applies force evenly from the bottom of the dumpling, ejecting it from the dough support cavity. The ejector mechanism, in conjunction with the external cylinder mechanism, enables automatic ejection of the dumplings after they are formed, improving dumpling production efficiency.

[0032] In this embodiment, the material feeding mechanism may further include a limiting frame 410, which is arranged parallel to the fixed plate below it. The material feeding rod is fixedly installed on the limiting frame, and an elastic element is provided between the limiting frame and the fixed plate.

[0033] After the ejector mechanism completes the ejection action, no additional drive components such as cylinders or motors are needed. The elastic element can automatically pull the limit frame towards the fixed plate to reset itself using its own elastic force. This, in turn, causes the ejector rod and ejector plate to fall back to their initial positions within the hollow mold base, achieving automatic and rapid reset of the ejector assembly. During the process of the ejector rod pushing the ejector plate upward to push the dumpling, the elastic element between the limit frame and the fixed plate can buffer the instantaneous impact force generated by the ejection action through its own deformation, reducing damage to the mating surfaces of the ejector plate and the bottom of the dumpling, and the ejector rod and the fixed plate caused by rigid impact.

[0034] In this embodiment, the hollow mold base and the support plate slide relative to each other. The support mechanism also includes a movable plate 230. One side of the movable plate has a limit groove and is movably connected to the mounting block by bolts. The other side is rotatably connected to the fixed plate. A top rod 221 is fixed on the side where the movable plate connects to the fixed plate.

[0035] While the top plate of the top feeding mechanism pushes the dumpling upward to demold, an external force acts on the top rod, driving the movable plate to rotate around the fixed plate, which in turn drives the supporting plate to descend synchronously, so that the dumpling is separated from the supporting cavity. This reduces the pushing resistance of the pushing mechanism, allowing the dumpling to leave the top plate without having to overcome a large resistance under the pushing mechanism of the top plate. This avoids local pulling caused by resistance with the inner wall of the supporting cavity, which could lead to dumpling skin breakage, wrinkling, deformation, or filling squeezing out.

[0036] In this embodiment, a roller 221 is installed at the end of the top rod.

[0037] When an external force drives the push rod to rotate the movable plate, the rollers convert the "sliding friction" between the push rod and the mating parts into "rolling friction," which can reduce the wear at the end of the push rod and reduce scratches, dents, and other damage to the surface of the mating parts caused by friction.

[0038] In this embodiment, the skin support mechanism further includes a guide rod 250, which is slidably engaged with the fixed plate, and the skin support plate has an interference fit hole corresponding to the guide rod; An elastic element 240 is provided between the support plate and the fixing plate, and the elastic element is fitted on the guide rod.

[0039] The guide rod and the fixed plate work together to provide axial guidance and constraint for the lifting and lowering movement of the support plate. After the support plate is driven to descend and complete demolding by external force, the elastic element can automatically push the support plate upward along the guide rod to return to its initial working position by its own elastic force. When the support plate is driven to descend by external force, the elastic element is compressed, absorbing the instantaneous impact force generated by the descent, which can reduce the rigid collision between the support plate and the fixed plate or the bottom of the hollow mold base; when the support plate rises and returns to its original position under the action of the elastic element, the elastic force of the elastic element is slowly released, slowing down the rising speed of the support plate and reducing its impact with the components above. The interference fit between the guide rod and the support plate can fix the guide rod and the support plate without affecting the assembly and disassembly efficiency of the support plate.

[0040] In this embodiment, an elastic layer is provided on the inner wall of the socket.

[0041] The elastic layer has a certain deformation capacity, which can adapt to the slight dimensional deviations between the guide rod and the socket, ensuring the tightness of the interference fit, reducing the difficulty of assembly, and minimizing damage to the support plate or guide rod caused by forced assembly.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
