Description

Technical Field

[0001] This invention belongs to the technical field of glutinous rice ball processing equipment, specifically relating to a glutinous rice ball cutting and decorating production line and production process. Background Technology

[0002] Tangyuan are spherical foods made from glutinous rice flour and other ingredients. They are usually filled and eaten cooked in soup. The variety of fillings for tangyuan is becoming increasingly diverse, including black sesame, peanut, fruit, flower, cheese, and meat fillings.

[0003] To automate the production of glutinous rice balls (tangyuan), tangyuan machines and production processes have developed rapidly. For example, Chinese patent documents CN112655730B, CN215013503U, and CN220255524U disclose a "fully automatic tangyuan machine," among others. These machines can all produce traditionally spherical tangyuan. To further shape the tangyuan, such as by adding decorative pieces, the process is usually done manually. These decorative pieces are typically made of dough. First, the dough is made, usually 1-2 mm thick, using a dough-making device similar to those in dumpling machines. Then, decorative pieces are cut manually from the dough, and these pieces can be various shapes such as leaves, fish, ovals, triangles, and pentagons. The decorative pieces are then manually pasted onto the glutinous rice balls. Currently, the above processing is a semi-automated production line, meaning that the production of the glutinous rice balls and the making of the dough are done using automated machinery; however, the cutting of decorative pieces from the dough and the pasting of the decorative pieces onto the glutinous rice balls are done manually. Therefore, the semi-automated production line has disadvantages such as low efficiency, poor consistency of finished products, and high labor costs. Summary of the Invention

[0072] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0073] The glutinous rice ball 10 in this application is an undecorated glutinous rice ball, which is spherical in shape. The decorated glutinous rice ball in this application refers to a semi-finished product formed by pressing the decorative piece 11 onto the glutinous rice ball 10.

[0074] The glutinous rice ball (tangyuan) cutting and decorating production line includes a frame 1, a dough-making device 2, a glutinous rice ball conveying device 4, a dough feeding conveying device 3, a dough-cutting and decorating device 5, and a glutinous rice ball shaping device 7. The dough-cutting and decorating device 5 and the glutinous rice ball shaping device 7 are arranged sequentially along the conveying direction L1 of the glutinous rice ball conveying device 4. The forming surface 731 of the glutinous rice ball shaping device 7 and the dough-cutting and decorating device 5 are located above the conveying surface of the glutinous rice ball conveying device 4. The dough-cutting and decorating device 5 includes a dough-cutting drive mechanism 510, a decorating drive mechanism 511, a mounting base 512, and a support. The machine includes a support base 513, a cutter holder 514, a mold holder 516, and at least one set of leather cutting and appliqué components; the support base 513, cutter holder 514, and mold holder 516 are arranged sequentially from top to bottom; the support base 513 is connected to the frame 1, the support base 513 is connected to the mold holder 516 via a connector, and the mounting base 512 is connected to the cutter holder 514; the leather cutting and appliqué components include a cooperating cutter 520 and a push rod 519; the cutter 520 is mounted on the cutter holder 514 and located below the cutter holder 514; the lower end of the cutter 520... A first cutting edge 5201 with a closed shape; a vertically arranged push rod 519 passes sequentially through the cutter holder 514 and the cutting tool 520, and is slidably engaged; the decal drive mechanism 511 is mounted on the mounting base 512, and the push rod 519 moves vertically up and down through the decal drive mechanism 511; the leather cutting decal assembly moves vertically up and down through the leather cutting drive mechanism 510; there is a leather conveying space 523 between the leather cutting processing surface on the mold base 516 and the cutter holder 514 for the leather to pass through; the mold base 516 has... A material discharge channel is provided that communicates with the dough conveying space 523. The material discharge channel is arranged coaxially with the first blade 5201. A second blade 5168 adapted to the first blade 5201 is provided at the upper end of the material discharge channel. The first blade 5201 and the second blade 5168 are arranged coaxially and used in conjunction. The feeding end of the dough feeding conveying device 3 is arranged correspondingly to the discharging end of the dough making device 2. The discharging end of the dough feeding conveying device 3 is arranged adjacent to the feeding end of the dough conveying space 523.

[0075] As attached Figure 1 , 2As shown, frame 1 provides mounting support for the dough-making device 2, the dough feeding and conveying device 3, the glutinous rice ball conveying device 4, and the dough cutting and appliqué device 5. The dough-making device 2 and the dough feeding and conveying device 3 are located to the side of the glutinous rice ball conveying device 4. Preferably, the discharge end of the dough-making device 2 is located above the feed end of the dough feeding and conveying device 3, so that the dough sheets exiting from the discharge end of the dough-making device 2 can fall onto the feed conveying surface of the dough feeding and conveying device 3. (See attached diagram) Figures 3-10 The illustrated cutting and appliqué device 5 has a support base 513 mounted on the frame 1, which is connected to the mold base 516 via a connector. A cutting drive mechanism 510 is mounted on the frame 1 and connected to a mounting base 512, which is mounted on a cutter holder 514. An appliqué drive mechanism 511 is mounted on the mounting base 512 and connected to the upper end of a push rod 519. A cutter 520 is mounted on the cutter holder 514, and the push rod 519 passes through the cutter holder 514 and the cutter 520 in a sliding fit.

[0076] The first blade 5201 and the second blade 5168 are adapted to each other, specifically meaning that the first blade 5201 and the second blade 5168 have the same shape and are fitted with a clearance. The skin-cutting and appliqué device 5 is located above the conveying surface of the glutinous rice ball conveying device 4, specifically meaning that the mold base 516 is located above the conveying surface of the glutinous rice ball conveying device 4.

[0077] The glutinous rice ball tray has grooves for placing individual glutinous rice balls, and the number of grooves can be set according to actual needs. Glutinous rice balls 10 are placed in the grooves on the tray, which is then placed on the conveying surface of the glutinous rice ball conveying device 4 for transport. When the dough is conveyed to the cutting surface and the tray is conveyed below the mold base 516, the conveying of the dough and tray stops, and the glutinous rice balls 10 in the tray are positioned directly below the material drop channel. Specifically, one glutinous rice ball corresponds to one material drop channel to ensure that one set of cutting and decorating components corresponds to one glutinous rice ball. At this time, the lower end of the push rod 519 is located in the cutter 520, and the cutting drive mechanism 510 drives the cutting and decorating components to move downwards in a straight line. Through the cooperation of the first blade 5201 and the second blade 5168, decorative pieces 11 that meet the requirements are cut out from the dough. The decal drive mechanism 511 then drives the ejector pin 519 to extend downwards from the lower end of the cutter 520, pressing the decorative piece 11 onto the top of the glutinous rice ball 10 to form a decal glutinous rice ball. This prevents the decorative piece from sticking crookedly. By setting the downward drive stroke of the decal drive mechanism 511, the stroke of the ejector pin 519 in each downward linear movement is kept consistent, thus ensuring consistent pressure on the decorative piece 11 and preventing damage to the glutinous rice ball, improving product consistency. The decal drive mechanism 511 drives the ejector pin 519 upwards in a linear motion, returning the lower end of the ejector pin 519 to the cutter 520; the skin-cutting drive mechanism 510 drives the skin-cutting decal assembly upwards in a linear motion, returning the skin-cutting decal assembly to above the mold base 516. The lower end surface of the ejector pin 519 is set as a plane. The glutinous rice ball conveying device 4 continues to convey the glutinous rice ball tray. When the tray is conveyed to the glutinous rice ball shaping device 7, and the forming surface 731 of the shaping device 7 is directly above the decorated glutinous rice ball, the shaping device 7 stops conveying. The forming surface 731 of the shaping device 7 presses down to adhere the decorative piece 11 to the glutinous rice ball 10, thus forming the finished decorated glutinous rice ball. This achieves fully automated operation of dough making, cutting the decorative piece 11 from the dough, and attaching the decorative piece 11 to the glutinous rice ball 10.

[0078] The support base 513 has various structural forms. Preferably, the support base 513 is a horizontally arranged plate structure with an installation window at its center, and the mounting seat 512 is located in the installation window. The upper surface of the support base 513 is connected to a handle 5131. There are two handles 5131, and the installation window is located between the two handles 5131.

[0079] The mounting base 512 can be an integral structure. Preferably, the mounting base 512 includes a first mounting bracket 5121 and a second mounting bracket 5122. Both the first mounting bracket 5121 and the second mounting bracket 5122 are mounted on the knife holder 514. The peeling drive mechanism 510 is connected to the first mounting bracket 5121, and the decal drive mechanism 511 is mounted on the second mounting bracket 5122.

[0080] The dough-making device 2 can adopt the dough-making mechanism of a dumpling machine, including a multi-stage dough-pressing mechanism. The dough feeding and conveying device 3 adopts an active belt conveyor mechanism, which includes a horizontally arranged feeding conveyor surface and a feeding drive motor that drives the feeding conveyor surface to move towards the dough conveying space 523. The glutinous rice ball conveying device 4 adopts an active belt conveyor mechanism or an active roller conveyor mechanism. The dough-making device 2, the dough feeding and conveying device 3, and the glutinous rice ball conveying device 4 are all existing technologies.

[0081] The connector can have various structural forms, including a plate-like structure. Specifically, the connector includes a column 517, and at least two columns 517 are provided, with the at least two columns 517 evenly distributed between the support base 513 and the mold base 516.

[0082] To improve the reliability of the up-and-down movement of the cutting appliqué assembly, a vertical motion guide mechanism is preferably included, through which the cutter holder 514 and the connector are connected via a transmission mechanism.

[0083] The vertical motion guide mechanism can be implemented in various ways, such as a slider-groove structure or a gear-rack structure. Preferably, the vertical motion guide mechanism includes a linear bearing 518 slidably mounted on the column 517, and the linear bearing 518 is fixedly connected to the cutter holder 514. The sliding engagement between the linear bearing 518 and the column 517 improves the reliability of the vertical movement of the cutter holder 514, thereby improving the reliability of the vertical movement of the leather appliqué assembly.

[0084] Because the dough has a certain degree of stickiness, the residual dough after cutting the decorative piece 11 easily sticks to the first cutting edge 5201 of the cutter 520. To solve the above technical problem, preferably, a material unloading seat 515 is also included between the cutter holder 514 and the mold holder 516. The bottom of the material unloading seat 515 has a material unloading surface; the material unloading seat 515 is provided with a through hole structure for the cutter 520 to pass through, and the through hole structure is coaxially arranged with the material dropping channel; the lower end of the through hole structure has a material unloading hole 5154, and the material unloading hole 5154 is adapted to the first cutting edge 5201; the material unloading seat 515 and the mold holder 516 are connected by a support member 522. By providing the material unloading seat 515, when the residual dough sticks to the first cutting edge 5201 and the cutting driving mechanism 510 drives the cutting appliqué assembly to move upward and reset, the material unloading surface at the bottom of the material unloading seat 515 prevents the residual dough from moving upward with the cutter 520, causing the residual dough to detach from the cutter 520. The discharge hole 5154 is adapted to the first cutting edge 5201. Specifically, the discharge hole 5154 and the first cutting edge 5201 have the same shape, are properly fitted together, and do not affect the up-and-down movement of the cutting tool 520. This improves the effect of removing residual material from the cutting tool 520 and avoids incomplete discharge. The discharge surface is preferably a horizontally arranged planar structure. The support member 522 can be a columnar structure, a vertically arranged plate structure, etc.

[0085] The unloading base 515 can be a one-piece molded structure. Preferably, the unloading base 515 includes an unloading base plate 5151 and an unloading plate 5152 arranged vertically. The unloading base plate 5151 and the unloading plate 5152 are both horizontally arranged and detachably connected. The bottom surface of the unloading plate 5152 serves as the unloading surface. The support member 522 connects the unloading base plate 5151 and the mold base 516. The through-hole structure includes a first through-hole 5153 and an unloading hole 5154 arranged vertically and coaxially. On the horizontal projection plane, the unloading hole 5154 is located within the first through-hole 5153. The first through-hole 5153 is disposed on the unloading base plate 5151, and the unloading hole 5154 is disposed on the unloading plate 5152. The unloading plate 5152 and the unloading base plate 5151 are detachably connected by bolts. When changing different cutting tools 520, the stripper plate 5152 used with the cutting tool 520 is also changed to ensure that the cutting tool 520 can extend downward through the stripper hole 5154 and that the residual material can be removed from the cutting tool 520. The first through hole 5153 on the stripper plate 5151 can be used with stripper holes 5154 of different sizes for processing decorative pieces 11 of different sizes.

[0086] The mold base 516 is provided with a horizontally arranged cutting surface, and the space between the cutting surface and the unloading surface serves as the surface material conveying space 523. After the surface material is conveyed to the cutting surface, the conveying is paused, and then the cutting action is performed. After the cutting action is completed, the pressing action is performed. After the cutting and appliqué components are reset, the surface material is conveyed into the surface material conveying space 523 again.

[0087] The mold base 516 can be a one-piece molded structure. Preferably, the mold base 516 includes a detachably connected template 5161 and a supporting base plate 5162. Both the template 5161 and the supporting base plate 5162 are horizontally arranged, with the template 5161 located above the supporting base plate 5162. The material discharge channel includes a material discharge hole 5164 and a second through hole 5165 arranged vertically and coaxially. The second cutting edge 5168 is disposed adjacent to the material discharge hole 5164 above it, and the second cutting edge 5168 and the material discharge hole 5164 are disposed on the template 5161. The second through hole 5165 is disposed on the supporting base plate 5162. The first through hole 5153, the unloading hole 5154, the material discharge hole 5164, and the second through hole 5165 are coaxially arranged. The template 5161 and the supporting base plate 5162 are detachably connected by bolts. In this case, the upper surface of the template 5161 serves as the surface for skin cutting. While changing different cutting tools 520, the template 5161 is also changed to ensure that the cutting tool 520 extends into the material drop hole 5164 and cuts out the decorative piece 11 through the cooperation of the first cutting edge 5201 and the second cutting edge 5168.

[0088] Because the dough has a certain degree of stickiness, to prevent the cut residue from sticking to the second cutting edge 5168 at the upper end of the material drop hole 5164, a third through hole 5166 is preferably included, which is disposed on the mold base 516 and coaxially arranged with the material drop channel. The third through hole 5166 is located above and adjacent to the second cutting edge 5168; on the horizontal projection plane, the second cutting edge 5168 is located within the third through hole 5166. The third through hole 5166 and the second cutting edge 5168 form a stepped structure. After the decorative piece 11 is cut from the dough, the cut edge of the residue is inclined downward towards the center of the second cutting edge 5168. Through its own elastic deformation, the cut edge of the residue retracts away from the second cutting edge 5168 to prevent the residue from sticking to the second cutting edge 5168. Preferably, the shape of the third through hole 5166 is consistent with the shape of the second cutting edge 5168.

[0089] The third through hole 5166 can be provided on the template 5161. Preferably, the template base 516 further includes a horizontally arranged panel 5163. The supporting base plate 5162 is provided with an upward-facing mounting groove 5167. The template 5161 is installed in the mounting groove 5167. The panel 5163 is detachably connected to the supporting base plate 5162 and covers the opening of the mounting groove 5167. The third through hole 5166 is provided on the panel 5163, and the second through hole 5165 is located at the bottom of the mounting groove 5167. At this time, the upper surface of the panel 5163 serves as the surface for cutting the skin. By providing the panel 5163, it is beneficial to process and form the third through hole 5166. The template 5161 is installed in the mounting groove 5167 on the supporting base plate 5162, and then the panel 5163 is connected to the supporting base plate 5162 by bolts.

[0090] Preferably, the panel 5163 extends towards the discharge end of the dough feeding and conveying device 3 and is arranged adjacent to the discharge end of the dough feeding and conveying device 3. This prevents the dough from collapsing downwards from the gap between the discharge end of the dough feeding and conveying device 3 and the feed end of the dough conveying space 523, thereby improving the conveying effect of the dough.

[0091] To prevent the outer layer from sticking to the panel 5163, preferably, an anti-stick layer is provided on the panel 5163. The anti-stick layer is preferably made of Teflon.

[0092] Preferably, the assembly also includes a connecting seat 521, the upper end of the top rod 519 being connected to the connecting seat 521, and the decal driving mechanism 511 being connected to the connecting seat 521; multiple sets of the cut-leather decal assembly are provided, and the top rod 519 in each set of the cut-leather decal assembly is connected to the connecting seat 521. The connecting seat 521 provides mounting support for the top rods 519 in the multiple sets of cut-leather decal assemblies.

[0093] When there is a horizontal distance between the discharge end of the dough-making device 2 and the feed end of the dough feeding conveyor 3, in order to ensure that the dough output from the discharge end of the dough-making device 2 can reliably fall onto the feed conveying surface of the dough feeding conveyor 3, preferably, a dough suspension conveyor 9 mounted on the frame 1 is also included. The dough suspension conveyor 9 has an inclined suspension conveying surface 901, which conveys dough from its lower end to its upper end. The discharge end of the dough-making device 2 is located above the suspension conveying surface 901, and the upper end of the suspension conveying surface 901 is located above the feed end of the dough feeding conveyor 3. The dough suspension conveyor 9 uses an active belt conveyor mechanism, which is existing technology. It includes a belt conveyor mechanism and a drive motor that drives the belt conveyor mechanism. The belt conveyor mechanism of the dough suspension conveyor 9 conveys dough upwards at an inclined angle via the drive motor. The frame 1 provides mounting support for the dough suspension conveyor 9. By setting up the dough sheet suspension conveyor 9, the dough sheets output from the discharge end of the dough-making device 2 fall onto the suspension conveyor surface 901 under the action of gravity. Then, through the suspension action of the high end of the suspension conveyor surface 901 and the conveying action of the suspension conveyor surface 901, the dough sheets fall onto the feeding conveyor surface of the dough sheet feeding conveyor 3. During the conveying process, the dough sheets are also prevented from collapsing downwards at the gap between the discharge end of the dough-making device 2 and the feeding end of the dough sheet feeding conveyor 3. The dough-making device 2 continuously outputs dough sheets, while the dough sheet feeding conveyor 3 intermittently conveys dough sheets. The suspension conveyor 9 also effectively prevents the dough sheets from piling up on the feeding conveyor surface of the dough sheet feeding conveyor 3.

[0094] Preferably, the system also includes a scrap dough discharge conveying device 6, with the discharge end of the dough conveying space 523 arranged adjacent to the feed end of the scrap dough discharge conveying device 6. The scrap dough discharge conveying device 6 is mounted on the frame 1 and employs an active belt conveyor mechanism, which is existing technology. The conveying speed and start / stop actions of the scrap dough discharge conveying device 6 and the dough feed conveying device 3 are kept consistent, which can be achieved by controlling the discharge drive motor of the scrap dough discharge conveying device 6 and the feed drive motor of the dough feed conveying device 3. This avoids pulling on the dough, which could cause deformation or even breakage.

[0095] Preferably, the scrap leather discharge conveying device 6 has a horizontally arranged discharge conveying surface, and the dough sheet feeding conveying device 3 has a horizontally arranged feeding conveying surface. As a further preferred embodiment, the feeding conveying surface of the dough sheet feeding conveying device 3, the cutting surface of the mold base 516, and the discharge conveying surface of the scrap leather discharge conveying device 6 are flush.

[0096] To facilitate the collection and reuse of residual hides, preferably, a residual hide recycling and conveying device 8 is also included; the inlet end of the residual hide recycling and conveying device 8 is arranged adjacent to the outlet end of the residual hide outlet conveying device 6, and the outlet end of the residual hide recycling and conveying device 8 is correspondingly located above the inlet end of the leather-making device 2. The residual hide recycling and conveying device 8 adopts an active belt conveyor mechanism, which is existing technology, and includes a belt conveyor mechanism and a recycling drive motor that drives the belt conveyor mechanism.

[0097] The peeling drive mechanism 510 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. Preferably, the peeling drive mechanism 510 includes a drive motor mounted on the frame 1, and the shaft extension end of the drive motor is connected to the first mounting bracket 5121 via a crank mechanism. The decal drive mechanism 511 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0098] As attached Figures 11-14 As shown, the glutinous rice ball shaping device 7 includes a support 710, on which a lifting mechanism 720 is provided. A forming mold 730 is mounted on the lifting mechanism 720 and can drive the forming mold 730 to rise and fall synchronously. A forming surface 731 is provided on the lower surface of the forming mold 730, and the forming surface 731 is an upwardly concave curved surface. When the forming mold 730 is at its lower limit position, the distance from the top of the forming surface 731 to the bottom surface of the decorated glutinous rice ball is less than the original height of the decorated glutinous rice ball. The forming surface 731 is located above the decorated glutinous rice ball, and multiple decorated glutinous rice balls are evenly arranged in a glutinous rice ball tray. The glutinous rice ball tray is located on the conveying surface of the glutinous rice ball conveying device 4, which conveys the decorated glutinous rice balls to the area below the forming surface 731.

[0099] In use, the lifting mechanism 720 drives the forming mold 730 and the forming surface 731 to descend synchronously, pressing the decorative piece 11 onto the glutinous rice ball 10 and ensuring a tight bond between the glutinous rice ball 10 and the inner surface of the decorative piece 11. At this point, the forming surface 731 adheres to the outer surface of the decorative piece 11, completing the shaping of the decal glutinous rice ball. After shaping, the decal glutinous rice ball enters the next process, and the lifting mechanism 720 drives the forming mold 730 to reset. During the shaping process, the decorative piece 11 and the glutinous rice ball 10 undergo a certain degree of plastic deformation, but this deformation is not easily noticeable to the naked eye. Using the lifting and movable forming surface 731 to compress the decal glutinous rice ball makes the adhesion between the glutinous rice ball 10 and the decorative piece 11 tighter, preventing them from separating and affecting the transportation and sale of the product, thus improving product quality; improving the consistency of the shape of the finished decal glutinous rice ball, enhancing its aesthetics, increasing production efficiency, and saving manpower.

[0100] The forming surface 731 is used to directly contact the decorated glutinous rice ball to shape it. It has various structural forms, and the shape of the forming surface 731 is designed according to the shape of the upper surface of the finished decorated glutinous rice ball. Preferably, the forming surface 731 is adapted to the shape of the upper surface of the glutinous rice ball 10, and the size of the forming surface 731 is greater than or equal to the size of the decorative piece 11 on the decorated glutinous rice ball. The aforementioned "shape adaptation" means that the shape of the forming surface 731 is the same as the shape of the upper surface of the glutinous rice ball 10, that is, the radius of curvature of the forming surface 731 and the upper surface of the glutinous rice ball 10 are equal. Generally, the forming surface 731 has a spherical cap structure. When the molding die 730 is at its lower limit position, the molding surface 731 is completely in contact with the decorative piece 11 on the decal glutinous rice ball. The molding surface 731 completely covers the decorative piece 11, so that the decorative piece 11 and the glutinous rice ball 10 are completely in contact and bonded together, eliminating the gap between the decorative piece 11 and the glutinous rice ball 10, increasing the contact area between the decorative piece 11 and the glutinous rice ball 10, further improving the bonding stability between the two, ensuring the consistency of the shape of the finished decal glutinous rice ball, and improving the product quality.

[0101] The bracket 710 is used to mount the entire device onto the mounting frame of the glutinous rice ball conveying device 4. It has various structural forms, including T-shaped brackets, L-shaped brackets, or portal frames. The bracket 710 generally uses a portal frame, which offers better stability and ease of installation. The portal frame is connected to the mounting frame of the glutinous rice ball conveying device 4 by bolts. The bracket 710 can be constructed from aluminum profiles and angle brackets, or from welded or bolted steel.

[0102] The lifting mechanism 720 is used to drive the forming mold 730 to move up and down. The lifting mechanism 720 has various structural forms; it can be a pneumatic, hydraulic, or electric actuator, or a screw assembly driven by a motor. Tangyuan (glutinous rice ball) production is a food manufacturing industry with strict hygiene requirements. Hydraulic actuators, electric actuators, and screw assemblies all require lubrication and are prone to oil leakage. Therefore, preferably, the lifting mechanism 720 is a pneumatic actuator, which is simple in structure and hygienic.

[0103] The molding die 730 can be a single, integral structure or multiple independent separate parts. The molding die 730 can be made of plastic, stainless steel, or other alloys. Considering that the molding die 730 will come into direct contact with the decorated glutinous rice balls during operation, preferably, the molding die 730 is made of 316 stainless steel. 316 stainless steel is food-grade stainless steel, which will not leach various alloys and harmful substances during food production, ensuring food safety.

[0104] In actual production, there are many types and sizes of decorated glutinous rice balls. To produce decorated glutinous rice balls of different heights, a height adjustment mechanism 740 is preferably included. The height adjustment mechanism 740 is used to adjust the lower limit position of the forming mold 730. The height adjustment mechanism 740 can adjust the lower limit position height of the forming surface 731 by adjusting the lifting stroke of the lifting mechanism 720, changing the position height of the lifting mechanism 720, or changing the position height of the forming mold 730. The lifting stroke of the lifting mechanism 720 is inconvenient to adjust. Therefore, the height adjustment mechanism 740 generally adjusts the lower limit position height of the forming surface 731 by adjusting the position height of the lifting mechanism 720 or the position height of the forming mold 730. The height adjustment mechanism 740 can be a strip hole provided along the height direction on the bracket 710, a height adjustment screw connecting the lifting mechanism 720 and the bracket 710, or multiple shims stacked along the height direction. Preferably, the height adjustment mechanism 740 includes a height adjustment screw, and the molding die 730 is mounted on the lifting end of the lifting mechanism 720 via the height adjustment screw. The height of the lower limit position of the molding die 730 can be changed by adjusting the height adjustment screw. The structure is simple and easy to adjust.

[0105] Generally, multiple decorated glutinous rice balls are evenly placed in a single glutinous rice ball tray. Preferably, the number of forming surfaces 731 is equal to the number of decorated glutinous rice balls in a single tray, and the position of the forming surfaces 731 is also equal to the number of decorated glutinous rice balls in a single tray. This allows for the simultaneous shaping of multiple decorated glutinous rice balls, improving production efficiency. Generally, the forming surfaces 731 are smooth and do not stick together when the decorated glutinous rice balls are pressed and attached, preventing damage to the surface of the finished product, ensuring the product's aesthetics, and improving product quality.

[0106] To further ensure a tight bond between the glutinous rice ball 10 and the decorative piece 11, preferably, the molding surface 731 is also provided with a downwardly protruding clamping member 732. During the descent of the molding die 730, the clamping member 732 contacts the decorative piece 11 before the molding surface 731 contacts it. Subsequently, the clamping member 732 descends synchronously with the molding surface 731 to the lower limit position, causing the decorative piece 11 to undergo plastic deformation and embed into the glutinous rice ball 10, thus achieving a seamless bonding between the glutinous rice ball 10 and the decorative piece 11. Without affecting the aesthetics of the finished decal glutinous rice ball, the clamping member 732 increases the contact area between the decorative piece 11 and the glutinous rice ball 10 by causing plastic deformation, thereby improving the overall integrity and quality of the finished product. When the design of the finished decal glutinous rice ball has a concave curved surface, the outer surface of the clamping member 732 becomes part of the molding surface 731, and the position on the decal glutinous rice ball that contacts the clamping member 732 forms the concave curved surface of the design. To ensure the aesthetic appeal of the finished decorated glutinous rice balls, the concave curved surface is generally positioned at the center of the upper surface. For example, when the decorative piece 11 is shaped like a persimmon calyx, a concave curved surface at the center of the decorative piece 11 makes the persimmon calyx shape more realistic. Specifically, to produce this type of decorated glutinous rice ball product, the pressing member 732 is located at the center of the forming surface 731. As a further preferred embodiment, multiple pressing members 732 are provided to further increase the contact area between the glutinous rice ball 10 and the decorative piece 11, thereby improving the adhesion and stability between them.

[0107] Preferably, the forming surface 731 is further provided with a forming pattern, which is used to press the pattern onto the decorative piece 11 while the decal-decorated glutinous rice ball is being shaped, further improving the aesthetic appeal of the finished decal-decorated glutinous rice ball. The shape of the forming pattern can be designed according to requirements.

[0108] The production process uses a glutinous rice ball cutting and decorating production line, including the following steps:

[0109] S1, the dough made by the dough making device 2 is conveyed by the dough feeding conveyor 3 to the cutting and appliqué station near the glutinous rice ball conveyor 4, and the glutinous rice ball tray containing the glutinous rice balls is conveyed by the glutinous rice ball conveyor 4 along the L1 direction.

[0110] The glutinous rice ball conveying device 4 has a cutting and appliqué station and a glutinous rice ball shaping station arranged sequentially along its own conveying direction L1. The cutting and appliqué device 5 is arranged corresponding to the cutting and appliqué station, and the glutinous rice ball shaping device 7 is arranged corresponding to the glutinous rice ball shaping station.

[0111] S2, when the dough is conveyed to the cutting surface and the glutinous rice ball tray is conveyed to the bottom of the mold base 516, the glutinous rice balls 10 in the tray are located directly below the material discharge channel, and the conveying of the dough and the tray stops; the lower end of the push rod 519 is located in the cutter 520, and the cutting drive mechanism 510 drives the cutting decal assembly to move downward in a straight line. After the decorative piece 11 is cut out on the dough through the cooperation of the first blade 5201 and the second blade 5168, the decal drive mechanism 511 drives the push rod 519 to move downward in a straight line. The push rod 519 extends downward from the lower end of the cutter 520 to press the decorative piece 11 onto the top of the glutinous rice ball 10 to form a decal glutinous rice ball;

[0112] S3, the decal drive mechanism 511 drives the ejector rod 519 to move upward in a straight line, so that the lower end of the ejector rod 519 is reset in the cutter 520; the leather cutting drive mechanism 510 drives the leather cutting decal assembly to move upward in a straight line, so that the leather cutting decal assembly is reset above the mold base 516.

[0113] S4, the decorated glutinous rice balls are shaped by the forming surface 731 of the glutinous rice ball shaping device 7, so that the decorative surface is bonded to the glutinous rice balls to form the finished decorated glutinous rice balls.

[0114] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. All equivalent changes made to the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
