[0045] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0046] See also Figure 1 The present invention provides a material stringing machine for completing material stringing, especially realizing mechanized assembly line material stringing operations, thereby improving material stringing efficiency, reducing labor costs, and avoiding accidental injuries caused by stringing.

[0047] In a specific embodiment, the stringing machine includes a material spreading platform 1, a material setting mechanism 2, a skewer stringing mechanism 3, a skewer supply mechanism 4, a material cutting mechanism 5 and a material unloading mechanism 6. The material spreading platform 1 is used to place food materials and keep the food materials in a fixed state so that the skewers 11 can pass through at one time; the skewer stringing mechanism 3 is used to push the skewers 11 toward the material spreading platform 1 so that the skewers 11 pass through the food materials to complete the stringing operation; the material setting mechanism 2 is used to press the food materials on the material spreading platform 1 during the stringing operation to ensure that the food materials will not shift when the skewer stringing mechanism 3 performs the stringing operation, thereby achieving the function of assisting the stringing; the skewer supply mechanism 4 is used to provide the skewers 11 in a row to the skewer stringing mechanism 3; the material cutting mechanism 5 is used to cut the food materials on the material spreading platform 1 into multiple portions; and the material unloading mechanism 6 is used to move the skewers 11 with food materials away from the material spreading platform 1.

[0048] The top surface of the material-laying platform 1 is provided with a material-discharging trough, such a configuration allows the food to be placed on the material-laying platform 1 without being easily displaced by external forces. The top surface of the material-laying platform 1 is provided with a skewer-threading groove that penetrates the material-laying platform and the material-discharging trough 1, that is, the skewer-threading groove penetrates the top surface of the material-laying platform 1 and the material-discharging trough, such a configuration allows the skewer to pass through the skewer-threading groove while also passing through the food on the material-laying platform 1, and the skewer can also be picked up from bottom to top at this time.

[0049] Since it is suitable for batch skewers, at least two skewers are provided, so that the ingredients on one material spreading platform 1 can be used to make multiple skewers. A cutter clearance groove is provided between adjacent skewers. The cutter clearance groove is used to make room for the cutter to cut the ingredients when cutting the ingredients, so that the cutter 506 can cut the ingredients. The depth of the cutter clearance groove is greater than the depth of the material placing groove, so that the cutter can cut through the ingredients and the ingredients can be cut.

[0050] See also Figure 1 In a preferred embodiment, a material transfer mechanism is also included, and the material transfer mechanism can move the material spreading platform to the material cutting mechanism, the stringing mechanism and the unloading mechanism respectively. Specifically, the material transfer mechanism includes a turntable 8 and a turntable rotation drive mechanism 9; the turntable 8 is used to support the material spreading platform 1, and the turntable rotation drive mechanism 9 is used to drive the turntable to rotate. The material spreading platform 1 is arranged on the turntable 8. The stringing mechanism 3, the material cutting mechanism 5, and the unloading mechanism are all arranged around the turntable, the material setting mechanism 2 is arranged on the turntable, and is arranged opposite to the stringing mechanism 3, and the signing mechanism 4 is arranged above the stringing mechanism 3.

[0051] In order to further improve the efficiency, in a preferred embodiment, four material spreading tables 1 are provided, and the four material spreading tables 1 are all provided on a turntable and three of them cooperate with the cutting mechanism, the stringing mechanism and the unloading mechanism respectively. After the three material spreading tables are placed with food, the four material spreading tables can respectively perform the cutting operation, the stringing operation, the unloading operation and the loading operation at the same time. In this way, the four material spreading tables 1 can be in different operations at the same time, thereby further improving the efficiency.

[0052] In a further embodiment, a whole machine bracket 10 is further included, and the whole machine bracket 10 is erected above the turntable, and the material ordering mechanism 2, the stringing mechanism 3, the supply mechanism 4, the cutting mechanism 5 and the unloading mechanism are all connected to the whole machine bracket 10.

[0053] The material setting mechanism 2 includes a pressing plate 200 and a pressing drive mechanism 201, and the bottom surface of the pressing plate 200 is adapted to the top surface of the material spreading platform 1. The body of the pressing drive mechanism 201 is connected to the whole machine support 10, and the output end of the pressing drive mechanism 201 is connected to the pressing plate 200, which is used to drive the pressing plate 200 to press down the material spreading platform 1 before stringing. Specifically, the pressing drive mechanism 201 can be a linear motor, a cylinder or an oil cylinder, and the output end of the pressing drive mechanism 201 is connected to the pressing plate 200.

[0054] In order to prevent the pressing plate 200 from pressing the food too tightly and damaging the food, in a further embodiment, pressure limiting protrusions are provided on both sides of the top surface of the material laying table 1, and the top of the pressure limiting protrusion is slightly higher than the top surface of the material laying table, and is used to press against the pressing plate 200 to limit the degree of compression of the pressing plate 200.

[0055] See also Figure 2 The signing mechanism 3 includes a signing table and a signing pushing mechanism. The signing table is used to arrange the signs that need to be threaded into the signing slot in sequence, and the signing pushing mechanism is used to push the signs placed on the signing table into the signing slot, thereby completing the signing operation.

[0056] The signing table is provided with a signing slot that runs through the signing table. By providing the signing table, the position of the signs placed on the signing table can be prevented from being offset, and the alignment of the signs with the sign-threading slot at the material laying table 1 can also be facilitated. There are at least two signing slots, and the spacing between adjacent signing slots is consistent with the spacing between adjacent sign-threading slots, that is, one signing slot corresponds to one sign-threading slot. When the signing slot and the sign-threading slot are aligned, the sign at the signing slot can be pushed to the sign-threading slot by a sign-pushing mechanism. The sign-pushing mechanism is provided on the signing table, and is used to drive the sign in the signing slot to be inserted into the sign-threading slot when the signing slot and the sign-threading slot are facing each other.

[0057] The length of the signing table is shorter than the length of the sign. When the sign is placed in the signing slot of the signing table, both ends of the sign are suspended. In a further embodiment, the sign pushing mechanism includes a roller, a roller rotation drive mechanism 304, a push plate 308 and a push plate drive mechanism 309. The roller is used to play the main role of driving the sign to move. The roller rotation drive mechanism 304 is used to drive the roller to rotate; the push plate 308 is used to assist the roller in driving the sign to move. Specifically, the push plate 308 moves the sign until the sharpened end of the sign is located at the roller; the push plate drive mechanism 309 is used to drive the push plate 308 to move. The push plate drive mechanism 309 can be a cylinder, an oil cylinder or a linear motor, and the output end of the push plate drive mechanism 309 is connected to the push plate 308.

[0058] The roller and the push plate 308 are respectively located at the two ends of the sign slot of the sign table. Specifically, the roller is located between the turntable and the sign table, and the sharpened end of the sign placed at the sign slot faces the roller. There are two rollers, which are arranged up and down. The two rollers are axially horizontal and arranged orthogonally to the sign slot. For the convenience of explanation, the roller located at the top is referred to as the upper roller 302, and the roller located at the bottom is referred to as the lower roller 303; there is a gap between the two rollers for the sign to pass through; the roller rotation drive mechanism 304 is connected to the roller transmission, and is used to drive the roller to rotate. The direction of the roller rotation is the direction that can drive the sign at the sign slot to move in the direction of the turntable, that is, drive the sign that passes through the gap to move away from the sign slot. The main driving force for the sign to move is the rolling drive of the two rollers. This driving method limits the thrust to the position close to the food. When the sign is subjected to resistance when the food is inserted, it avoids the problem of the sign being broken due to the thrust and resistance being too far apart, and can ensure the smooth movement of the sign.

[0059] See also Figure 3 In one embodiment, a circular sign-giving slot 3020 is provided on the outer wall of one of the rollers, and preferably a circular sign-giving slot 3020 is provided on the outer wall of the lower roller 303; the slot cavity of the sign-giving slot 3020 is the gap, and such a setting can not only leave a gap between the two rollers for the sign to pass through, but also play a role in limiting the trajectory of the sign movement, ensuring that the sign moves accurately from the list sign slot to the corresponding pass-through slot. The number of sign-giving slots 3020 is consistent with the number of list sign slots; each sign-giving slot 3020 is arranged in sequence along the axial direction of the roller, and the spacing between adjacent sign-giving slots 3020 is consistent with the spacing between adjacent list sign slots, that is, one sign-giving slot 3020 corresponds to one list sign slot, and one sign-giving slot 3020 corresponds to one pass-through slot.

[0060] In a further embodiment, an upper roller bracket 305 and a roller lifting drive mechanism 306 are also included; the upper roller bracket 305 is arranged at the whole machine bracket 10, and the roller located above (i.e., the upper roller 302) can be axially rotatably arranged at the upper roller bracket 305, and the roller rotation drive mechanism 304 is arranged at the upper roller bracket 305, and is connected to the roller located above (i.e., the upper roller 302). Specifically, the roller rotation drive mechanism 304 can be a rotating motor, which can be connected by a coupling, a gear, or a belt.

[0061] The roller lifting drive mechanism 306 is transmission-connected to the upper roller bracket 305, and is used for driving the upper roller away from the lower roller, or approaching to the roller circumscribed to the lower roller. Specifically, the roller lifting drive mechanism 306 can be a cylinder, an oil cylinder or a linear motor. The body of the roller lifting drive mechanism 306 is connected to the whole machine bracket 10, and the output end of the roller lifting drive mechanism 306 is connected to the upper roller bracket 305. Such an arrangement allows the upper roller 302 to be lifted or lowered. When the sharpened end of the stick has not yet been pushed between the two rollers, the upper roller 302 is in a lifted state. When the sharpened end of the stick has been pushed between the two rollers, the upper roller 302 can be lowered to abut against the lower roller 303, and the roller rotation drive mechanism 304 can be started to drive the stick to move. In this way, the upper roller 302 can be prevented from affecting the stick to be pushed into the stick yielding slot 3020, and the stick in the stick yielding slot 3020 can be driven to move.

[0062] The stringing mechanism 3 also includes a lower roller bracket 307; the roller located below is axially rotatably arranged at the lower roller bracket 307 through a bearing, and the lower roller bracket 307 can also be arranged at the whole machine bracket 10. If the turntable is provided with four material laying platforms 1, at this time, in a preferred embodiment, four lower rollers 303 can be provided, and the four lower rollers 303 are respectively arranged on the side walls of the turntable through four lower roller brackets 307, and are respectively arranged opposite to the four material laying platforms 1. The sign giving slot 3020 of each lower roller 303 is respectively arranged opposite to the sign passing slot of each material laying platform 1, that is, each material laying platform 1 is equipped with a lower roller 303.

[0063] See also Figure 4 In order to avoid affecting the operation of supplying signatures, in a further embodiment, a moving platform is further included, the moving platform is arranged at the whole machine bracket 10, the signing table is arranged on the moving platform, the moving platform is used to drive the signing table to move close to or away from the roller, when the signing mechanism 4 is in the state of issuing signatures, the signing table is in a state of being away from the roller, when the signing mechanism 4 completes issuing signatures, the moving platform can drive the signing table to move close to the roller with the signatures until the sharpened end of the signature is located at the signature yielding groove 3020, on this basis, the push plate 308 and the push plate driving mechanism 309 can be omitted, that is, the signatures on the signing table are moved to the signature yielding groove 3020 by relying on the moving platform; because there is friction in the process of the signatures moving to the signature yielding groove 3020, therefore, the push plate 308 and the push plate driving mechanism 309 can also be provided, that is, in the process of the signatures on the signing table moving to the signature yielding groove 3020 by relying on the moving platform, the push plate 308 and the push plate driving mechanism 309 assist the moving platform to make the signatures enter the signature yielding groove 3020.

[0064] In a further embodiment, the mobile platform includes a base 310, a pallet 311 and a pallet driving mechanism 312; the base 310 is connected to the whole machine support 10, and the pallet 311 is arranged at the base 310 so as to be linearly movable; the pallet driving mechanism 312 is connected to the pallet 311 for driving the pallet 311 to move linearly; the sign-in table is arranged on the pallet 311. Specifically, a first slide rail 314 may be arranged at the bottom of the pallet 311, a first slider 313 may be arranged on the base 310, and the first slide rail 314 may be slidably connected to the first slider 313; the push plate driving mechanism 309 may be a cylinder, an oil cylinder or a linear motor, and the linear motor may be a lead screw motor.

[0065] See also Figure 6 Before the signing is done, the signing mechanism 3 needs to provide the signing sticks, which are provided by the signing stick supply mechanism 4. In a specific embodiment, the signing stick supply mechanism 4 includes a signing bucket 400 and a signing stick removing mechanism; the signing bucket 400 is used to hold the signing sticks, and the signing stick removing mechanism is used to remove the signing sticks from the signing bucket 400 one by one. The signing bucket 400 is arranged above the signing table and can move relative to the signing table. The moving direction is orthogonal to the direction of the signing slots, and the distance of a single movement is the spacing between adjacent signing slots. Such a setting enables the signing bucket 400 to drop the signing sticks into each signing slot in turn. The initial position of the signing bucket 400 is directly opposite to the signing slot closest to the side.

[0066] The bucket 400 is used to place the sticks horizontally. The sticks lie horizontally and are placed horizontally in the bucket 400. A stick outlet 4000 is provided at the bottom of the bucket 400. The size of the outlet 4000 is only for a single stick to pass horizontally, that is, the outlet 4000 is for a single stick to pass through, and is arranged horizontally and in a strip shape. The longitudinal width of the inner cavity of the bucket 400 gradually decreases from top to bottom to the outlet 4000. Such a setting can not only make the sticks move downward gradually, but also limit the number of sticks that move downward gradually, ensuring that the number of sticks close to the outlet 4000 is not large.

[0067] The stick-picking mechanism is connected to the stick bucket 400 and is used to push the sticks out of the stick outlet 4000 one by one and drop them into the stick slots in sequence. The stick-picking mechanism includes a connecting rod 401, a thumbwheel 402 and a connecting rod rotation driving mechanism 403; the connecting rod 401 is horizontally arranged outside the stick bucket 400; the thumbwheel 402 is sequentially provided with stick-picking protrusions on its circumference, see Figure 7The thumbwheel 402 is arranged in series on the connecting rod 401, and the thumbstick-picking protrusion passes into the thumbstick bucket 400 and blocks the thumbstick outlet 4000, that is, the thumbstick-picking protrusion can just cover the cross section of the place where it passes, so that each rotation of the thumbwheel can only push a single thumbstick to the bottom of the thumbwheel. The connecting rod rotation drive mechanism 403 is connected to the connecting rod in a transmission manner, and is used to drive the connecting rod to drive the thumbwheel to rotate and push the thumbsticks out of the thumbstick outlet 4000 one by one. Specifically, the connecting rod rotation drive mechanism 403 can be a rotary motor; the connecting rod rotation drive mechanism is arranged on the outer wall of the thumbstick bucket 400, and the output end of the connecting rod rotation drive mechanism is connected to the connecting rod in a transmission manner.

[0068] In a further embodiment, the sign bucket 400 is provided with a thumbwheel hole 4001 for the thumbwheel projection to pass through, and the size of the thumbwheel hole is larger than the size of the thumbwheel, so that the thumbwheel passing through will not affect the rotation of the thumbwheel.

[0069] In order to better move the sign, in a preferred embodiment, at least two thumbwheels are provided, and the two thumbwheels are fixedly arranged in series on the connecting rod.

[0070] In a preferred embodiment, at least one pair of baffles 404 is further included, and each pair of baffles 404 includes two baffles 404; the baffles are all located under the sign bucket 400, and the top ends of the baffles are connected to the bottom surface of the sign bucket 400; the two baffles of each pair of baffles are arranged opposite to each other, and a guide channel connected to the sign outlet 4000 is formed therebetween; the bottom end of the guide channel faces the sign-listing platform, and such an arrangement can guide the sign from the sign outlet 4000 to fall accurately into the sign-listing slot.

[0071] See also Figure 5In order to realize that the signing table can move longitudinally with the signing slot relative to the signing bucket 400, in a certain embodiment, the signing table includes a screw 300 and a screw rotation driving mechanism 301, and the screw rotation driving mechanism 301 can be a rotary motor; the signing slot is a threaded groove 3000 on the side wall of the screw 300; the screw 300 is provided with at least two screws, each screw 300 is arranged in parallel, and the position of the threaded groove 3000 is consistent; the screw rotation driving mechanism 301 is connected to the screw 300 for driving the screw 300 to rotate to transport the sign. Driven by the screw rotation drive mechanism 301, the screw 300 rotates and the thread groove 3000 of the screw 300 moves, that is, the thread groove 3000 drives the ticket to move along the length direction of the screw 300 through the thread transmission.
