In the traditional production process, the demoulding process mainly relies on manual operation. The high-temperature mold box is manually inverted and knocked, and the soup base is separated from the box body by physical vibration. Then, the demoulding soup base is clamped to the packaging station using tools. However, the efficiency of manual demoulding is limited by the worker's operating speed, resulting in high labor intensity and low demoulding efficiency for the workers, which cannot meet the large-scale production needs of the modern food industry. In order to solve the above technical problems, the prior art has a technology that relies on heating to separate the hot pot soup base from the box body, such as the demoulding production line disclosed in the patent document with the publication number CN111439562A, which heats the surface of the hot pot soup base to melt so that it is separated from the box body. However, the use of heating to separate the hot pot soup base from the box body requires precise control of the heating temperature and heating area, otherwise it will cause the hot pot soup base to melt over a large area, which is difficult to control.

Through the sliding cooperation between the L-shaped support module and the first arc-shaped mold support track, during the chain transmission process, the mold support track can guide the movement of the sliding connection part, thereby realizing the progressive opening action of the mold support mechanism at a preset position. The expansion force is applied to the side walls of the mold box through the L-shaped support module, so that the side walls of the box body are opened to both sides, the side walls of the box body are separated from the product, and the product is separated from the box body under the action of its own gravity, thereby realizing automatic demolding of the product.

During this process, the box body is flipped 180°; The demoulding module continues to drive the box body to move toward the demoulding channel, and the product in the box body is separated from the box body in the demoulding channel by the combined action of the demoulding module and the die pressing module; The separated product slides down from the drop opening of the limiting groove to the third conveying module, and the product is conveyed to the packaging equipment for product packaging through the third conveying module; The box body after demoulding continues to stay in the limiting groove and continues to move along the chain movement direction of the first sprocket transmission mechanism, and falls from the end of the demoulding module to the second conveying module, and is driven by the second conveying module to be conveyed to the cleaning system; The product in the box body is in the demoulding channel, and the demoulding module and the pressing module work together to separate the product from the box body, including: The supporting module enters from one end of the first arc section of the supporting mold track and continues to move along the first arc section. The distance between the two groups of supporting modules gradually increases. The supporting module stretches the side wall of the box body outward, and the side wall of the box body is gradually separated from the side of the product. After the supporting module moves a preset length along the first arc segment, the pressing rod enters from one end of the third arc segment of the pressing track and continues to move along the pressing track, and the height of the pressing rod gradually decreases, and the pressing rod with continuously decreasing height presses the bottom of the box; at this time, the extrusion rod also enters from one end of the second arc segment of the extrusion track and continues to move along the extrusion track, and the distance between the two groups of extrusion rods gradually decreases, and the extrusion rods with continuously decreasing distance squeeze the edge of the bottom of the box inward; the pressing rod presses the bottom of the box and the extrusion rod squeezes the edge of the bottom of the box inward, so that the bottom of the box is concave downward, pushing the product to move toward the mouth of the box body until the product is completely separated from the box body.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a list of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0026] As mentioned in the background technology, manual demoulding is inefficient and cannot meet the large-scale production needs of the modern food industry. The use of heating to separate the hot pot base from the box requires precise control of the heating temperature and heating area, otherwise the hot pot base will melt over a large area and be difficult to control.

[0027] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, the present invention provides the following embodiments.

[0028] Embodiment 1: This embodiment provides an automatic demoulding and packaging system for hot pot soup base. Figure 1 As shown, the demoulding packaging system includes a demoulding module 300, which receives the box body 900 grabbed by the transfer module 200 from the first conveying module 100. After the transfer module grabs the box body, it drives the box body to flip 180°, and the demoulding module drives the box body to move. When it moves to a preset position, the side walls of the box body are opened to both sides, so that the product 800 is separated from the box body and falls to the third conveying module 700. The product is driven to move to the product packaging equipment through the third conveying module. The box body stays on the demoulding module and continues to move to the end of the demoulding module, and falls onto the second conveying module 600. The box body is driven to move to the cleaning system through the second conveying module. Specifically, taking hot pot soup base as an example, the first conveying module, the second conveying module and the third conveying module can select belt conveyors and chain conveyors. The first conveying module is connected to the cooling and molding equipment of the hot pot soup base, and the box body and the hot pot soup base after cooling and molding inside it are transported to the grabbing module through the first conveying module; in this embodiment, the grabbing module can be a flipping clamp cooperating with a mechanical arm, and the mechanical arm can drive the flipping clamp to approach the box body, and the flipping clamp clamps or absorbs the box body, and the mechanical arm moves again to drive the box body to move toward the demolding module. In this process, the flipping clamp The rotating clamp will flip the box body 180°, thereby turning the box body upside down on the demoulding module; the second conveying module can be arranged below one end of the demoulding module to receive the empty box body dropped from one end of the demoulding module, and the second conveying module can be connected to the box body cleaning equipment, through which the empty box body can be conveyed to the box body cleaning equipment for cleaning, and the third conveying module can be arranged below the preset position of the demoulding module. When the hot pot base material is separated from the assembly and falls onto the third conveying module, the third conveying module can be connected to the packaging equipment, through which the hot pot base material can be driven to move toward the packaging equipment.

[0029] Specifically, Figure 2 , 3 As shown, the demoulding module includes: A first power unit 310; A first sprocket transmission unit 320, which is connected to the first power unit and drives the first sprocket transmission unit to move through the first power unit; A limiting unit 330, which is fixed on the chain of the first sprocket transmission unit and is arranged equidistantly along the moving direction of the chain, and defines the opening of the accommodating box body; A die support unit, which is provided with an array, wherein the die support units of the array are arranged corresponding to the limit units, and each group of the die support units includes a pair of oppositely arranged die support mechanisms 360, the die support mechanisms are in contact with the inner side wall of the box body mouth, and the die support mechanisms are connected to the chain through the telescopic mechanism 350; The mold support rail 340, such as Figure 6 As shown, the mold support track is provided with two groups, and the two groups of mold support tracks are arranged opposite to each other. The upper part of the mold support track has a first arc section 341 bent along the opening direction of the box body. Each mold support mechanism of each group of mold support units is slidably arranged on the two groups of mold support tracks, and the mold support mechanism moves along the mold support track with the movement of the chain. like Figure 7 As shown, the mold support mechanism may include: A first sliding connection part 363, which is slidably connected to the mold support track and is driven to move along the mold support track by the movement of the chain; The supporting module 361 is L-shaped as a whole, and one end of the supporting module is connected to the first sliding connection part.

[0030] Specifically, the demoulding module also includes a first frame, and the first power unit and the first sprocket transmission unit are both installed on the first frame. The first power unit can select a servo motor, a stepper motor or other devices that can realize the movement of the first sprocket transmission unit. A T-shaped groove can be set on the outer surface of the mold support track, and the end of the first sliding connection part can be set to a T-shaped block matching the T-shaped groove, a guide wheel or other structures that can slide and match the T-shaped groove. In addition, in addition to the T-shaped groove, other guide structures can also be set. For example, two sets of guide wheels can be set at the end of the first sliding connection part, and the two sets of guide wheels clamp the track inside and contact the side of the track.

[0031] For example, Figure 8 As shown, the telescopic mechanism may include: A fixed rod 352, one end of which is fixedly connected to the chain of the first sprocket transmission unit; The movable rod 351 is partially wrapped in the fixed rod and keeps relative sliding with the fixed rod. One end of the movable rod is fixedly connected to the first sliding connection part, and a spring 353 is installed on the part of the movable rod wrapped in the fixed rod.

[0032] Specifically, when the support module moves in the first arc segment, the support module will stretch or squeeze the movable rod, so that the movable rod moves linearly along its own axis, thereby achieving connection with the chain while avoiding interference with the movement of the support module perpendicular to the conveying direction.

[0033] When this embodiment is in use, the box body and the hot pot base materials after cooling and forming inside it are conveyed toward the grabbing module through the first conveying module. The grabbing module grabs the box body on the first conveying module and drives the box body to move toward the demolding module. During this process, the grabbing module will flip the box body 180°, and then place the box body upside down in the limiting unit. The first power unit drives the first sprocket transmission mechanism to move, and the limiting unit moves with the chain of the first sprocket transmission mechanism to drive the box body in the limiting unit to move together. At the same time, the chain of the first sprocket transmission mechanism will drive the supporting module to move along the supporting mold track. When the supporting module enters from one end of the first arc segment of the supporting mold track and continues to move along the first arc segment, the distance between the two groups of supporting modules gradually increases, and the supporting module will stretch the side wall of the box body outward, and the side wall of the box body and the side of the product Gradually separate, the product gradually separates from the box body under the action of its own gravity and falls onto the third conveying module, and the product is driven to move toward the packaging equipment through the third conveying module, while the empty box body continues to stay in the limiting unit and continues to move toward the end of the demoulding module with the limiting unit. When the support module moves to the midpoint of the first arc segment, the distance between the two groups of support modules reaches the maximum. Thereafter, as the support module continues to move, the distance between the two groups of support modules begins to gradually decrease until the support module leaves the first arc segment. At this time, the distance between the two groups of support modules reaches the minimum, and no longer forms stretching or contact with the side wall of the box body. When the box body moves to the end of the demoulding module, it continues to move and flip with the sprocket drive unit, and falls onto the second conveying module under the action of its own weight, and the empty box body is driven to move toward the box body cleaning equipment through the second conveying module.

[0034] Through this embodiment, the entire process of box grabbing, flipping, mold support, material removal and recycling is automated, thereby improving production efficiency. Through the sliding cooperation between the L-shaped support module and the first arc-shaped mold support track, during the chain transmission process, the mold support track can guide the movement of the sliding connection part, thereby realizing the progressive opening action of the mold support mechanism at a preset position. The L-shaped support module applies an expansion force to the side walls of the mold box, so that the side walls of the box body are opened to both sides, the side walls of the box body are separated from the product, and the product is separated from the box body under the action of its own gravity, thereby realizing automatic demolding of the product. At the same time, the packaging efficiency is improved by arranging multiple sets of mold support mechanisms along the movement direction of the chain.

[0035] For example, Figure 3 As shown, the limiting unit may include: A first limiting plate 331, which is provided with two groups, and the two groups of the first limiting plates are arranged opposite to each other and are fixed to the chain; Second limiting plates 332, which are provided in four groups, with every two groups of the second limiting plates being fixed on one group of the first limiting plates, and the four groups of the second limiting plates being arranged opposite to each other; A limiting groove defining the opening of the accommodating box body is formed between the four groups of the second limiting plates and the two groups of the first limiting plates, and a drop opening for the product to fall is provided in the middle of the limiting groove.

[0036] In this embodiment, a double constraint is formed by the limiting groove composed of the first limiting plate and the second limiting plate, thereby ensuring that the box body remains in a preset position and improving the placement and positioning accuracy of the box body. The drop opening in the middle of the limiting groove provides a vertical falling channel for the product, which is convenient for the product to be discharged from the box body.

[0037] For example, Figure 4 , 5 As shown, a first waist-shaped hole 331B is provided at the connection between the first limiting plate and the chain, and a second waist-shaped hole 331A is provided at the connection between the first limiting plate and the second limiting plate; In this embodiment, the first limit plate is fixedly connected to the chain link of the chain of the first sprocket transmission unit by a first bolt, the first bolt passes through the first waist-shaped hole and the chain link from top to bottom, and the first nut is threadedly installed to fix the first limit plate, the second limit plate includes a connecting portion 332A and a limiting portion 332B vertically arranged with the connecting portion, a connecting hole 332C is provided on the connecting portion corresponding to the second waist-shaped hole, the connecting hole and the second waist-shaped hole are sequentially driven by the second bolt, and the second nut is threadedly installed to achieve relative fixation of the second limit plate and the first limit plate; like Figure 7 As shown, the mold support mechanism also includes a connecting rod 362, which is fixed to the first sliding connection part, and a third waist-shaped hole 364 is provided at both ends of the connecting rod. A threaded rod is provided at one end of the support module, and the threaded rod passes through the third waist-shaped hole. The connecting rod is clamped inside by two sets of nuts threadedly engaged on the threaded rod to keep the support module and the connecting rod fixed.

[0038] Before demolding, the first limit plate and the second limit plate can be slid according to the specifications of the box body to adjust the distance between the two groups of first limit plates and the distance between the second limit plates on the same group of limit plates. At the same time, the support module can be slid horizontally to adjust the distance between the two groups of support modules in the same group of support mechanisms and the distance between the two groups of support mechanisms. After the adjustment is completed, tighten the nuts of the respective connecting bolts to fix them.

[0039] The position adjustment of the limit unit in the horizontal and vertical directions is realized through the first waist-shaped hole at the connection between the first limit plate and the chain and the second waist-shaped hole at the connection between the first limit plate and the second limit plate. The support module and the connecting rod adopt the double nut locking structure of the third waist-shaped hole and the threaded rod, so that the horizontal position and extension length of the support module can be flexibly adjusted according to the internal contour of the box body, so that the size of the limit slot and the position of the support module can be adjusted according to the specifications of the box body, thereby improving the practical flexibility of the system.

[0040] In addition, in this embodiment, Figure 1 As shown, the demoulding packaging system may further include a die pressing module 500, which is arranged above the demoulding module corresponding to the mold support track, and the die pressing module presses the bottom of the box body to eject the product.

[0041] For example, Fig. 9 As shown, the die module comprises: A second power unit 510; A second sprocket transmission unit 520, which is connected to a second power unit and driven by the second power unit to move in a direction parallel to the movement direction of the first sprocket transmission unit; A pressing unit 550 is connected to the chain of the second sprocket transmission unit. Fig.10 As shown, the pressing unit includes a pressing rod 552; The pressing rail 540, the pressing rod is slidably fitted on the pressing rail, and the pressing rod moves along the pressing rail along with the movement of the second sprocket. Fig.12 As shown, the top pressing track includes a top mold track 542, and a third arc segment 542A that bends vertically downward is provided at the lower portion of the top mold track corresponding to the first arc segment of the supporting mold track.

[0042] In this embodiment, the die module may also include a second frame, and the top pressing rail, the second power unit and the second sprocket transmission unit can all be installed on the second frame, and connected to the first frame through the second frame, so that the second sprocket transmission unit is parallel to the top of the first sprocket transmission unit as a whole, and the second power unit can select a servo motor, a stepper motor or other devices that can realize the movement of the second sprocket transmission unit.

[0043] Specifically, when the box body is driven to the entrance of the demoulding channel formed by the demoulding module and the pressing module, the pressing rod is above the bottom of the box, and the pressing unit moves synchronously with the box body in the demoulding channel. When the pressing rod enters from one end of the third arc section of the pressing track and continues to move along the pressing track, the height of the pressing rod gradually decreases, and the pressing rod that continuously decreases in height presses against the bottom of the box to make the bottom of the box concave downward, pushing the product to move toward the mouth of the box body until the product is completely separated from the box body. When the pressing rod moves to the midpoint of the third arc section, the height of the pressing rod reaches the lowest point. As the pressing unit continues to move, the height of the pressing rod gradually increases, and the bottom of the box gradually returns to its original state until the pressing rod leaves the third arc section. At this time, the distance between the two sets of extrusion rods reaches the minimum, and no longer extrudes or contacts the side walls of the box body.

[0044] In this embodiment, the first arc segment 341 of the mold support track guides the support module to laterally expand the side wall of the box body to separate the side of the product from the side wall of the box body, and the third arc segment of the pressing track guides the pressing rod to lower its height, thereby applying vertical pressing pressure to the bottom of the box body to improve the demolding effect of the product.

[0045] In addition, if Fig.10 As shown, the pressing unit may further include a pressing rod 554, which is arranged on both sides of the pressing rod opposite to each other, and an L-shaped groove matching the edge of the box bottom is provided at the end of the pressing rod; The die module further comprises an extrusion track 530, which is arranged corresponding to the extrusion rod, and one end of the extrusion rod away from the L-shaped groove is slidably matched with the extrusion track. Fig.11 As shown, a second arc segment 531 is provided at the lower part of the extrusion track corresponding to the third arc segment and is bent in a direction opposite to the expansion direction of the box body side wall.

[0046] When the pressing rod enters from one end of the third arc section of the pressing track and moves continuously along the pressing track, the height of the pressing rod gradually decreases, and the pressing rod with a continuously decreasing height presses the bottom of the box; at this time, the extrusion rod also enters from one end of the second arc section of the extrusion track and moves continuously along the extrusion track, and the spacing between the two groups of extrusion rods gradually decreases, and the extrusion rods with a continuously decreasing spacing squeeze the edge of the bottom of the box inward; through the pressing of the bottom of the box by the pressing rod and the squeezing of the edge of the bottom of the box inward by the squeezing rod, the bottom of the box is concave downward, pushing the product to move toward the mouth of the box body until the product is completely separated from the box body; when the supporting module moves to the midpoint of the first arc section, the squeezing rod also moves to the midpoint of the second arc section, and the spacing between the squeezing rods reaches the minimum. As the pressing unit continues to move, the spacing between the squeezing rods increases, and the bottom of the box gradually returns to its original state, until the pressing rod leaves the third arc section and the squeezing rod leaves the second arc section. At this time, the spacing between the two groups of squeezing rods reaches the minimum, the height of the pressing rod reaches the maximum, and no longer squeezes or contacts the side wall of the box body; In this embodiment, the curvature trajectory of the second arc section of the extrusion track is opposite to that of the first arc section of the support mold track, so that the extrusion rod can tighten the edge of the box bottom inward, cooperate with the support module to expand the side wall of the box body outward, reduce the demoulding resistance, and through the inward extrusion of the extrusion rod and the downward pressing of the pressing rod to press the bottom of the box, the bottom of the box shrinks inward and sinks downward, thereby forming a downward driving force on the bottom of the product, which can push the product downward, thereby improving the separation efficiency of the product and the box body.

[0047] For example, Fig.10As shown, the pushing unit also includes a connecting plate 551, and the extrusion rod and the pushing rod are both installed on the connecting plate. The connecting plate is kept connected with the chain of the second sprocket transmission unit. A sliding groove 551A extending along the expansion direction parallel to the side wall of the box body is provided at the connection between the connecting plate and the extrusion rod. The extrusion rod is inserted in the sliding groove. A sliding sleeve 553 is also fixed on the connecting plate. The pushing rod is inserted in the sliding sleeve and maintains a sliding fit with the sliding sleeve.

[0048] In this embodiment, the extrusion rod, the pressure rod and the second sprocket transmission mechanism are connected through a connecting plate, so that the extrusion rod and the pressure rod can move synchronously when the second sprocket mechanism moves. By setting a sliding groove and a sliding sleeve, the movement of the extrusion rod or the pressure rod can be constrained without interfering with the horizontal linear movement of the extrusion rod perpendicular to the chain movement direction or the vertical linear movement of the pressure rod, thereby improving the movement accuracy of the extrusion rod and the pressure rod.

[0049] In this embodiment, a guide track 541 is further provided on the outer side of the top mold track and is arranged parallel to the chain of the second sprocket transmission unit, and the sliding sleeve is slidably fitted in the guide track.

[0050] In this embodiment, the cooperation mode between the top mold track and the top pressure rod, and the cooperation mode between the extrusion track and the extrusion rod can refer to the cooperation mode between the above-mentioned support mold track and the support module.

[0051] For example, Fig.13 As shown, the die module may also include: An adjusting portion 570, which is fixed on the extrusion track; The screw rod 560 is threadably matched with the adjusting portion.

[0052] In this embodiment, the position of the extrusion track can be adjusted by the threaded cooperation between the screw rod and the adjusting part.

[0053] In addition, a hand wheel, a motor or other device or structure capable of driving the screw to rotate can be installed at the position of the screw of the second frame to facilitate the staff to control the rotation of the screw.

[0054] For example, Figure 1 As shown, the demoulding packaging system may further include a lifting module 400, which is disposed between the demoulding module and the die pressing module, and drives the die pressing module to move vertically linearly; like Fig.14 As shown, the lifting module includes: A mounting portion 450, which is fixed to the side of the demoulding module and has a second guide groove 451; A third power unit 440, the third power unit is mounted on the mounting portion; A slide plate 430, which is connected to the third power unit and has a pulley disposed in the second guide groove mounted on the slide plate; A cross-link structure 420, the bottom of which is pivotally connected to the mounting portion and the slide plate respectively; A lifting part 410 is fixed to the die module, and a first guide groove 411 is provided on the lifting part. A pulley matching the first guide groove is provided on the top of the cross-link structure.

[0055] Specifically, the third power unit can be selected from a pneumatic cylinder, an electric cylinder, a hydraulic cylinder or other linear drive devices. In this embodiment, the third power unit can drive the slide plate to move horizontally linearly along the second guide groove, thereby driving the connecting rods of the cross-connection structure to rotate relative to each other along the rotating axis of their intersection, changing the angle between the connecting rods, thereby realizing the lifting and lowering movement of the lifting part.

[0056] In this embodiment, the pressing die module can be driven to vertically move up and down by the lifting module, thereby achieving height adjustment of the pressing die module.

[0057] Embodiment 2: This embodiment provides a method for automatically demoulding and packaging a hot pot soup base. The method uses an automatic demoulding and packaging system for hot pot soup base described in Embodiment 1. The method comprises: S100: The first conveying module drives the box body to move toward the grabbing position, wherein the box body contains the product formed into a solid state by self-flow cooling; Specifically, the self-flowing cooling and forming into a solid state is as follows: after the box body is sequentially filled with the bottom material layer, the oil layer and the dry material in a flowing state in a filling device, it is gradually cooled and solidified into a block-shaped hot pot bottom material in the cooling device.

[0058] S200: The grabbing module grabs the box body that moves to the grabbing position, and drives the box body to move toward the demoulding module. During this process, the box body is turned over 180°; S300: the demoulding module continues to drive the box body to move toward the demoulding channel, and the product in the box body is separated from the box body in the demoulding channel by the demoulding module and the pressing module; Specifically, the box body is placed into the limiting groove of the demoulding module by the grabbing module, and at this time, the supporting module extends into the box body from the opening of the box body; The first power unit drives the first sprocket transmission mechanism to move, and the first limit plate and the second limit plate move with the chain of the first sprocket transmission mechanism to drive the box body in the limit groove to move together, and the chain of the first sprocket transmission mechanism drives the supporting module to move along the supporting mold track; the second power unit drives the second sprocket transmission mechanism to move, and the top pressure unit moves with the second sprocket transmission mechanism; like Fig.15As shown, when the box body is driven to the inlet of the demoulding channel formed by the demoulding module and the pressing module, the edge of the box bottom is in the L-shaped groove of the extrusion rod, the pressing rod is above the box bottom, and the pressing unit moves synchronously with the box body in the demoulding channel; like Fig.16 As shown, when the supporting module enters from one end of the first arc segment of the supporting mold track and continues to move along the first arc segment, the distance between the two groups of supporting modules gradually increases, the supporting module stretches the side wall of the box body outward, and the side wall of the box body is gradually separated from the side of the product; When the push rod enters from one end of the third arc section of the push rail and moves continuously along the push rail, the height of the push rod gradually decreases, and the push rod with a continuously decreasing height presses the bottom of the box; at this time, the extrusion rod also enters from one end of the second arc section of the extrusion rail and moves continuously along the extrusion rail, and the distance between the two groups of extrusion rods gradually decreases, and the extrusion rods with a continuously decreasing distance squeeze the edge of the bottom of the box inward; the push rod presses the bottom of the box and the extrusion rod squeezes the edge of the bottom of the box inward, so that the bottom of the box is concave downward, and the product is pushed to move toward the mouth of the box body until the product is completely separated from the box body; In this embodiment, after the molding module enters from one end of the first arc segment and continues to move a preset distance, the pressing rod and the extrusion rod begin to enter the third arc segment and the second arc segment respectively.

[0059] S400: The detached product slides from the drop opening of the limiting groove to the third conveying module, and the third conveying module conveys the product to the packaging equipment for product packaging; S500: the box body after demoulding continues to stay in the limiting groove and continues to move along the chain movement direction of the first sprocket transmission mechanism, falls from the end of the demoulding module to the second conveying module, and is driven by the second conveying module to be conveyed to the cleaning system; Specifically, due to the restrictions of the first limiting plate and the supporting module, the box body will always remain in the limiting groove. When the limiting unit continues to drive the box body to move, when the supporting module moves to the midpoint of the first arc segment, the distance between the two groups of supporting modules reaches the maximum. As the supporting module continues to move, the distance between the two groups of supporting modules begins to gradually decrease until the supporting module leaves the first arc segment. At this time, the distance between the two groups of supporting modules reaches the minimum, and no longer forms stretching or contact with the side wall of the box body. When the supporting module moves to the midpoint of the first arc segment, the top pressure rod moves to the midpoint of the third arc segment, the height of the top pressure rod reaches the minimum, the extrusion rod also moves to the midpoint of the second arc segment, and the distance between the extrusion rods reaches the minimum. As the top pressure unit continues to move, the height of the top pressure rod gradually increases, the distance between the extrusion rods increases, and the bottom of the box gradually returns to its original state, until the top pressure rod leaves the third arc segment and the extrusion rod leaves the second arc segment. At this time, the distance between the two groups of extrusion rods reaches the minimum, the height of the top pressure rod reaches the maximum, and no longer forms an extrusion or contact with the side wall of the box body; The empty box body continues to move along the limiting groove to the end of the demoulding module, and falls onto the second conveying module under the action of the box body's own gravity, and the box body is conveyed to the cleaning system through the second conveying module.
