Description

Technical Field

[0001] This utility model relates to a rolling and forming equipment for round and square skins, belonging to the technical field of food machinery and equipment. Background Technology

[0002] Traditional round and square dumpling wrappers are made by manually pressing them using molds, which requires a lot of manpower and has low output, making it difficult to meet the needs of industrial production. With the rapid development of the food industry, people have higher requirements for the size, thickness, and quality of dumpling wrappers. To meet the needs of the food industry, CN202323274264.X discloses a dumpling wrapper forming machine. Through the combination of electro-hydraulic push rods, pressure plates, forming blocks, and forming grooves, the electro-hydraulic push rods are controlled to move the forming blocks downwards to cut and shape the dumpling wrappers. Although different sizes of dumpling wrappers can be produced by changing the forming molds, only a single shape of dumpling wrappers can be produced. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the problems existing in the prior art and provide a round and square skin rolling forming equipment with high production capacity and good quality.

[0004] The technical solution of this utility model to solve its technical problem is as follows: A round and square leather rolling forming equipment includes a round leather rolling mold mechanism, a square leather rolling mold mechanism, and a rolling mold conveyor. The rolling mold conveyor is located below the round leather rolling mold mechanism and the square leather rolling mold mechanism. The round leather rolling mold mechanism includes a round leather rolling mold, and a set of mold pieces are provided on the outer circumferential surface of the round leather rolling mold. The round leather rolling mold is connected to the rolling mold drive motor of the rolling mold conveyor. The square leather rolling mold mechanism includes a square leather rolling cutter, and the square leather driving cutter is connected to the square leather driving motor.

[0005] The further improved technical solution of this utility model is as follows:

[0006] Preferably, the end of the round skin rolling die is movably connected to a bearing seat mounted on an adjusting handwheel via a rotating bearing, the adjusting rod of the adjusting handwheel is threadedly connected to a bushing, and the bushing is mounted on the frame of the round skin rolling die mechanism.

[0007] This invention allows for the adjustment of the handwheel to control the up-and-down movement of the round skin rolling die, thereby adjusting the distance between the round skin rolling die and the conveyor belt of the rolling die conveyor, and thus adjusting the state of the round skin rolling die. When the round skin rolling die moves downward, the rolling die drive motor drives the round skin rolling die to run; when the round skin rolling die moves upward, the round skin rolling die does not perform rolling and cutting.

[0008] Preferably, the rolling die conveyor includes a round skin drive roller, a round skin drive roller gear, a rolling die conveying drive roller, and a rolling die conveying belt. The rolling die conveying drive roller and the round skin drive roller are respectively connected to a rolling die drive motor. The rolling die conveying belt covers the surface of the rolling die conveying drive roller and extends to the rolling die conveying passive roller. The round skin drive roller gear is located at the end of the round skin drive roller and meshes with the round skin rolling die gear.

[0009] Preferably, the input end of the roll forming conveyor is connected to the dough conveyor belt, and the dough conveyor belt is provided with a dough cutting mechanism. The dough cutting mechanism includes a cutting knife assembly, and the cutting knife assembly is connected to a cutting knife motor.

[0010] In the above structure, when the equipment produces square wrappers, the wrappers are fed into the strip-cutting assembly, where they are cut into strips of the required width for wonton wrappers. These strips are then conveyed to the roller conveyor. When the equipment produces round wrappers, the wrappers are directly conveyed to the roller conveyor without passing through the strip-cutting assembly.

[0011] Preferably, the output end of the rolling die conveyor is connected to the input end of the leather making conveyor, and the output end of the leather making conveyor is connected to the input end of the leather receiving conveyor.

[0012] Preferably, the leather conveying mechanism includes a leather conveying conveyor belt and a leather conveying drive roller. The leather conveying drive roller is connected to a leather conveying drive motor. The leather conveying conveyor belt covers the surface of the leather conveying drive roller and extends to the leather conveying passive roller.

[0013] Preferably, the skin-receiving conveying mechanism includes a skin-receiving conveyor belt, a skin-receiving conveying drive motor, and a skin-receiving conveying drive roller. The skin-receiving conveying drive roller is connected to the skin-receiving conveying drive motor, and the skin-receiving conveying drive roller is connected to the skin-receiving passive roller via the skin-receiving conveyor belt.

[0014] Preferably, the output end of the rolling die conveyor is also connected to the input end of the round leather residue crushing mechanism, and the input end is provided with a square leather residue crushing mechanism.

[0015] Preferably, the round leather scrap crushing mechanism includes a round leather scrap conveyor, scrap crushing blades, a first cutting blade assembly, and a scrap crushing output conveyor. The input end of the round leather scrap conveyor is connected to the output end of the rolling die conveyor. A set of scrap crushing blades is provided below the output end. The first cutting blade assembly is provided below the scrap crushing blades. The scrap crushing output conveyor is provided below the first cutting blade assembly. The output end of the scrap crushing output conveyor is provided with a collection and concentration frame.

[0016] In this way, the round leather rolling die mechanism rolls and cuts the whole sheet of dough into several round leathers, which are then conveyed to the leather making conveyor mechanism and the round leather residue crushing mechanism. The residual leathers after the round leathers are produced enter the round leather residue conveyor and are then conveyed to the residual leather crushing knife and the first cutting knife assembly for crushing. The round leathers produced by rolling and cutting fall onto the leather making conveyor belt of the leather making conveyor mechanism under the action of gravity.

[0017] Preferably, the square leather scrap crushing mechanism includes a crushing motor, a second cutting blade assembly, and a flow plate. The crushing motor is connected to the second cutting blade assembly, the flow plate is arranged facing the inlet of the second cutting blade assembly to convey the square leather scraps to the second cutting blade assembly, and a collection frame is provided below the outlet of the second cutting blade assembly.

[0018] With the above structure, before the strips of dough produced by the dough cutting mechanism enter the roller conveyor, the dough ends of the strips are manually fed into the flow plate, guided by the flow plate into the second cutting assembly, cut by the second cutting assembly, and fall into the collection box.

[0019] This utility model's equipment has two working states: round leather forming and square leather forming. During round leather forming, the round leather rolling die mechanism and the round leather residue crushing mechanism are in operation. During square leather forming, the surface leather cutting mechanism, the square leather rolling die mechanism, and the square leather residue crushing mechanism are in operation. In both states, the rolling die conveyor, the leather making conveyor, and the leather receiving conveyor are all running.

[0020] The advantages of this invention are that it uses a rolling cut method to produce round and square wrappers, resulting in a compact structure, high degree of automation, and convenient maintenance and disassembly. This not only greatly reduces labor costs but also significantly increases the yield of wrappers, improves production efficiency, and enhances product quality to a certain extent. It is suitable for production lines of noodle products such as dumpling wrappers and wonton wrappers. Attached Figure Description

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. However, the present invention is not limited to the examples given.

[0040] like Figure 1 and Figure 16As shown, a round and square leather rolling forming equipment includes a round leather rolling mold mechanism 1, a square leather rolling mold mechanism 2, a rolling mold conveyor 3, a leather making conveyor 4, a round leather scrap crushing mechanism 5, a leather receiving conveyor 6, a square leather scrap crushing mechanism 7, a dough strip cutting mechanism 9, and a frame 8. The round leather rolling mold mechanism 1, the square leather rolling mold mechanism 2, the dough conveyor 3, the leather making conveyor 4, and the round leather scrap crushing mechanism 5 are all fixed to the frame 8 by bolts. The round leather rolling mold mechanism 1, the square leather rolling mold mechanism 2, and the round leather scrap crushing mechanism 5 are located above the frame 8. The rolling mold conveyor 3 is located below the round leather rolling mold mechanism 1 and the square leather rolling mold mechanism 2. The leather making conveyor 4 is located behind the rolling mold conveyor 3. The round leather scrap crushing mechanism 5 is located above the leather making conveyor 4. The leather receiving conveyor 6 is installed at the tail end of the frame 8, and the square leather scrap crushing mechanism 7 is installed at the front end of the frame 8. The dough sheet produced by the dough pressing unit is conveyed to the dough sheet cutting mechanism 9 via a conveyor. The dough sheet cutting mechanism 9 cuts the dough sheet into the required strips. The cut strips are then conveyed to the input end of the roller mold conveyor 3 via a conveyor belt. The output end of the roller mold conveyor 3 is connected to the input end of the dough making conveyor 4 and the round dough scrap crushing mechanism 5, respectively. Both round dough rolling and square dough rolling are completed on the conveyor belt of the roller mold conveyor 3. At the same time, the roller mold conveyor 3 conveys the rolled round or square dough to the rear dough making conveyor 4 via a conveyor belt. The output end of the dough making conveyor 4 is connected to the input end of the dough receiving conveyor 6.

[0041] like Figure 6 and Figure 7As shown, the roller die conveyor 3 includes a roller die conveying side frame 301, a round drive roller 302, a round drive roller gear 303, a square drive roller 304, a roller die conveying drive roller 305, and a roller die conveying belt 306. The roller die conveying side frame 301 is fixedly connected to the frame 8 by bolts. Roller die conveying passive rollers are respectively provided at both ends of the roller die conveying side frame 301. The roller die conveying passive rollers are connected to the roller die conveying drive roller 305 through the roller die conveying belt 306, and a tensioning pulley is abutted on the outgoing belt. The round drive roller 302 and the square drive roller 304 are both mounted on the roller die conveying side frame 301, and the shafts of the round drive roller 302 and the square drive roller 304 are movably connected to the roller die conveying side frame 301 through bearings to realize the free rotation of the round drive roller 302 and the square drive roller 304. During the square skin rolling process, the square skin drive roller 304 supports the conveyor belt, preventing the square skin from being cut incompletely when rolling on the conveyor belt at step 203. There are two sets of round skin drive rollers 302, each with a gear 303 at its shaft end. The rolling die conveying drive roller 305 and any set of round skin drive rollers 302 are connected to the rolling die drive motor via a conveyor belt. Specifically, the rolling die drive motor is installed inside the frame 8, and its output end is connected to a central drive shaft via a coupling. Each end of the central drive shaft is equipped with a drive pulley; one drive pulley is connected to the driven pulley of the round skin drive roller 302 via the conveyor belt, and the other drive pulley is connected to the driven pulley of the rolling die conveying drive roller 305 via the conveyor belt.

[0042] like Figure 2 and Figure 3 As shown, the round skin rolling mold mechanism 1 includes a round skin rolling mold mechanism frame 101, an adjusting handwheel 104 mounted on the frame 101, and a round skin rolling mold 102. The round skin rolling mold mechanism frame 101 is mounted on a frame 8 and can be disassembled and replaced as a whole. The round skin rolling mold 102 is cylindrical and is mounted on the round skin rolling mold mechanism frame 101 via the adjusting handwheel 104. Specifically, the two ends of the round skin rolling mold 102 are movably connected to bearing seats via bearings, enabling the free rotation of the round skin rolling mold 102. The bearing seats are connected to the lower end of the adjusting handwheel 104. A round skin rolling mold gear 103 is provided at the shaft end of the round skin rolling mold 102, and the round skin rolling mold gear 103 meshes with the round skin drive roller gear 303. In this way, when the rolling die drive motor drives the round skin drive roller 302 to rotate through the conveyor belt, the round skin rolling die 102 is driven to rotate through the meshing between the round skin rolling die gear 103 and the round skin drive roller gear 303.

[0043] A set of die plates is provided on the outer circumference of the round skin rolling die 102. The die plates can be annular protrusions, with the outward-facing ends of the protrusions sharpened to form cutting blades. The size of the die plates is the same as the size of the round skin to be produced, but the size of the die plates on the round skin rolling die 102 can be customized according to customer requirements, facilitating the production of round skins of different specifications. When different specifications of round skins need to be rolled, the size of the die plates can be adjusted by changing the round skin rolling die 102. When the round skin rolling die 102 rotates, it drives the die plates on it to rotate together, so that the die plates contact the skin on the rolling die conveyor 3, thereby rolling and cutting out the round skin.

[0044] A shaft hole is provided at the end of the frame 101 of the round leather rolling die mechanism, and a bushing is installed in the shaft hole. The adjusting handwheel 104 includes a handwheel and an adjusting rod. The handwheel is installed at the upper end of the adjusting rod, and the lower end of the adjusting rod is connected to a bearing seat. The end bearing of the round leather rolling die 102 is set in the bearing seat. The adjusting rod is set in the bushing, and the outer surface of the adjusting rod is provided with an external thread. The inner wall of the bushing is provided with an internal thread that matches the external thread, so that the adjusting rod and the bushing are connected by a threaded engagement. By rotating the handwheel, the adjusting rod is controlled to move up and down relative to the bushing, which in turn moves the round leather rolling die 102 up and down through the bearing seat. The distance of the up and down movement of the round leather rolling die 102 is controlled by the adjusting handwheel 104. There are two adjusting handwheels 104 and two sets of round leather rolling dies 102. Each adjusting handwheel 104 corresponds to one set of round leather rolling dies 102. The die pieces on the two sets of round leather rolling dies 102 are of different sizes, which can roll cut two specifications of round leather. During round leather cutting, one set of round leather cutting dies 102 is raised by adjusting handwheel 104 and does not participate in the cutting operation; the other set of round leather cutting dies 102 is lowered by adjusting handwheel 104, and is simultaneously driven to rotate by the cutting die drive motor to perform round leather cutting. When changing the size of the round leather to be cut, it is necessary not only to control the raising or lowering of the round leather cutting die 102 by adjusting handwheel 104, but also to replace the round leather drive roller 302 corresponding to the round leather cutting die 102 to be used and connect it to the cutting die drive motor.

[0045] The round leather rolling mechanism 1 rolls and cuts a whole sheet of dough into several round pieces, which are then conveyed to the leather-making conveying mechanism 4 and the round leather residue crushing mechanism 5. At this time, the front end of the residual leather after the round pieces are produced is manually fed into the round leather residue conveyor 501 of the round leather residue crushing mechanism 5. Under the action of traction force, the subsequent residual leather automatically enters the round leather residue conveyor 501 and is then conveyed to the residual leather crushing blade 502 and the first cutting blade assembly 503 for crushing. The round pieces produced by rolling and cutting fall onto the leather-making conveyor belt 402 of the leather-making conveying mechanism 4 under the action of gravity.

[0046] like Figure 17As shown, the dough sheet cutting mechanism 9 includes a dough sheet cutting frame 901, a dough sheet cutting conveyor 902, a cutting knife assembly 903, and a dough sheet cutting frame wall panel 904. The dough sheet cutting frame wall panel 904 is mounted on the dough sheet cutting frame 901. The dough sheet cutting conveyor 902 and the cutting knife assembly 903 are both mounted on the dough sheet cutting frame wall panel 904. The cutting knife assembly 903 is located below the input end of the dough sheet cutting conveyor 902. A dough sheet conveyor 905 is located below the dough sheet cutting frame wall panel 904. The cutting knife assembly 903 includes a pair of interlocking toothed rollers, one of which is connected to the cutting knife motor via a gearbox. The dough sheet is conveyed by the dough sheet cutting conveyor 902 to the cutting knife assembly 903, where it is cut into strips of the required width for wonton wrappers. These strips then fall into the dough sheet conveyor 905, which transports them to the rolling die conveyor 3. It should be noted that during round wrapper forming, the entire dough sheet is directly conveyed to the rolling die conveyor 3 via the dough sheet conveyor 905, without needing to be cut into strips by the dough sheet cutting mechanism 9.

[0047] like Figure 4 and Figure 5 As shown, the square dough rolling mechanism 2 includes a square dough rolling mechanism frame 201, a square dough drive motor 202, and a square dough rolling cutter 203. The square dough rolling mechanism frame 201 is bolted to the frame 8. The square dough drive motor 202 is mounted on the square dough rolling mechanism frame 201 and connected to the power input shaft of the square dough rolling cutter 203. There are two sets of square dough rolling cutters 203, which are mounted on a cutter holder connected to the power input shaft. The square dough drive motor 202 drives the cutter holder to rotate, causing the square dough rolling cutter 203 to contact the dough on the rolling mold conveyor 3, thus achieving square dough rolling and cutting. During square dough rolling and cutting, the strip-shaped dough is conveyed to the bottom of the square dough rolling mechanism 2 via the rolling mold conveyor 3. The square dough drive motor 202 drives the square dough rolling cutter 203 to rotate, cutting the strip-shaped dough into square wonton wrappers.

[0048] like Figure 8 and Figure 9As shown, the leather-making conveying mechanism 4 includes a leather-making conveying side frame 401, a leather-making conveying belt 402, and a leather-making conveying drive roller 403. The leather-making conveying side frame 401 is fixedly connected to the frame 8 by bolts. Both ends of the leather-making conveying side frame 401 are respectively equipped with leather-making conveying passive rollers. The leather-making conveying drive roller 403 is connected to a leather-making conveying drive motor. The leather-making conveying belt 402 covers the surface of the leather-making conveying drive roller 403 and extends to the leather-making conveying passive roller, with a tensioning pulley abutting on the return belt. The rolling die conveyor 3 and the leather-making conveying mechanism 4 are each a separate integrated conveyor. The entire conveyor can be quickly disassembled for easy maintenance and replacement of vulnerable parts. The rolled round or square leather is conveyed to the leather-making conveying mechanism 4 via the rolling die conveyor 4, and then the leather-making conveying mechanism 4 conveys the round or square leather to the receiving conveyor 6 at the rear.

[0049] like Figure 11 and Figure 12 As shown, the leather receiving and conveying mechanism 6 includes a leather receiving conveyor belt 601, a leather receiving conveying drive motor 602, a leather receiving conveying drive roller 603, and a leather receiving conveying side frame 604. The leather receiving conveying side frame 604 is fixedly connected to the frame 8 by bolts. The leather receiving conveying drive roller 603 is installed at one end of the leather receiving conveying side frame 604, and a leather receiving passive roller is installed at the other end of the leather receiving side frame 604. The leather receiving conveying drive roller 603 is connected to the leather receiving conveying drive motor 602, and the leather receiving drive roller 603 is connected to the leather receiving passive roller through the leather receiving conveyor belt 601. The leather receiving conveying drive motor 602 is servo controlled. The round or square leathers to be collected are stacked to a certain height before being conveyed to the subsequent equipment. The round or square leathers are conveyed to their tail end by the leather making conveyor mechanism 4, flipped, and fall onto the leather receiving conveyor mechanism 6. The leather receiving conveyor mechanism 6 pauses operation. After the round or square leathers are stacked to a certain height on the leather receiving conveyor mechanism 6, operation resumes, and the round or square leathers are conveyed to the subsequent equipment.

[0050] like Figure 10 and Figure 11As shown, the round leather scrap crushing mechanism 5 includes a round leather scrap conveyor 501, scrap crushing blades 502, a first cutting blade assembly 503, and a scrap crushing output conveyor 504. The round leather scrap conveyor 501 is mounted on the scrap crushing wall panel of the frame 8. The input end of the round leather scrap conveyor 501 is connected to the output end of the roller mold conveyor 3. A set of scrap crushing blades 502 is provided below the output end of the round leather scrap conveyor 501. The first cutting blade assembly 503 is provided below the scrap crushing blades 502. The scrap crushing output conveyor 504 is provided below the first cutting blade assembly 503. The output end of the scrap crushing output conveyor 504 is provided with a collection and concentration frame. The scrap crushing blades 502 include a pair of interlocking toothed rollers. A set of blades is formed on the surface of the toothed rollers. The distance between adjacent blades is 20mm. One of the toothed rollers is connected to the scrap crushing blade motor through a gearbox. The first cutting blade assembly 503 includes a pair of symmetrically arranged cutting blades. Each cutting blade consists of a shaft and cutting blades mounted on the shaft. The cutting blades of the two cutting blades are tangential. The shaft of one of the cutting blades is connected to a motor, which drives the cutting blade to rotate, thus achieving tangential cutting by the two cutting blades. The round leather scraps produced by the round leather rolling die mechanism 1 are manually fed into the round leather scrap conveyor 501. The round leather scraps are conveyed by the round leather scrap conveyor 501 to the scrap shredder 502, where the scrap shredder 502 shreds the whole scrap into several strips 20mm wide. The strips fall into the first cutting blade assembly 503 below, where they are cut into pieces. The pieces fall into the scrap shredder output conveyor 504, and are output by the scrap shredder output conveyor 504 into a collection and gathering frame.

[0051] like Figure 14 and Figure 15 As shown, the square leather scrap crushing mechanism 7 includes a scrap crushing side frame 701, a crushing motor 702, a second cutter assembly 703, and a flow plate 704. The scrap crushing side frame 701 is fixedly connected to the frame 8 by bolts. The crushing motor 702 is mounted on the scrap crushing side frame 701 and connected to the second cutter assembly 703. The flow plate 704 is arranged facing the inlet of the second cutter assembly 703 to convey square leather scraps to the second cutter assembly 703. A collection frame is provided below the outlet of the second cutter assembly 703. The second cutter assembly 703 consists of a pair of symmetrically arranged cutters. Each cutter consists of a shaft and cutting blades mounted on the shaft. The cutting blades of the two cutters are tangent to each other. The shaft of one of the cutters is connected to the crushing motor 702, driving the cutter to rotate, thus achieving the tangency of the two cutting blades. Before entering the roller conveyor 3, the strips of dough produced by the dough cutting mechanism 9 are manually fed into the flow plate 704. The dough strips are then guided by the flow plate 704 into the second cutter assembly 703, where they are cut and fall into the collection box.

[0052] In actual operation, before the square dough sheet is rolled and cut, the dough sheet is conveyed to the dough sheet cutting mechanism 9, where the cutting knife assembly 903 operates to cut the entire dough sheet into multiple long strips. The entire dough sheet or the strips are then conveyed to the round dough sheet rolling mechanism 1 or the square dough sheet rolling mechanism 2 via the rolling die conveyor 3. The round dough sheet rolling die 102 or the square dough sheet rolling cutter 203 operates to roll and cut the dough sheet into round or square pieces (round and square dough sheets cannot operate simultaneously). The residual dough pieces generated during round dough sheet rolling are manually fed onto the round residual dough sheet conveyor 501. These residual dough pieces are then conveyed to the residual dough sheet crushing knife 502, which crushes the entire residual dough sheet into 20mm wide strips. These strips then fall into the first cutting knife assembly 503 below and are cut into... Countless small pieces of scrap leather, cut into small pieces, eventually fall onto the scrap leather crushing and output conveyor 504, which outputs the scrap leather into a collection and gathering frame. Meanwhile, the round or square leather produced by the round leather rolling die 102 or the square leather rolling cutter 203 is conveyed backward by the rolling die conveyor belt 306 to the leather making conveyor mechanism 4. After being conveyed backward by the leather making conveyor mechanism 4, the round or square leather flips over and falls onto the leather receiving conveyor mechanism 6 at the end of the leather making conveyor mechanism 4. When the round or square leather is stacked to a certain height, the leather receiving conveyor mechanism 6 conveys the round or square leather to the rear equipment.

[0053] The advantage of this invention is that it adopts a rolling cutting mode, which not only ensures the quality of round and square skins, but also greatly increases the output of round and square skins.

[0054] In addition to the embodiments described above, this utility model may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
