Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dumpling machines, in particular to a stuffing conveying device for a dumpling machine. BACKGROUND

[0002] With the acceleration of the industrialization of food, as the core equipment for batch production of dumplings, the stability of the stuffing conveying mechanism of the dumpling machine directly determines the production efficiency and product quality. At present, the main stuffing conveying mechanism of the dumpling machine on the market adopts the combination structure of feeding hopper, spiral blade and conveying pipeline. The spiral blade is driven to rotate by the motor, and the axial extrusion force of the spiral angle of the blade is used to continuously push the stuffing in the feeding hopper to the conveying pipeline, and finally to the dumpling wrapping station, realizing automatic feeding.

[0003] At present, when the stuffing in the feeding hopper is consumed to the vicinity of the spiral blade, on the one hand, the connection between the bottom of the feeding hopper and the conveying pipeline has an angle or a dead angle due to the structure, and the stuffing is easy to flow slowly due to its own viscosity and is easy to accumulate at the bottom of the feeding hopper, which cannot be effectively grabbed by the spiral blade. On the other hand, the spiral blade needs to rely on the continuous filling of the stuffing to generate stable extrusion force. When the blade is near the lack of material, the blade idles, cannot apply enough pushing force to the remaining stuffing in the conveying pipeline, and the stuffing in the pipeline stagnates and accumulates, which causes the lack of stuffing or the leakage of stuffing at the dumpling wrapping station, and even the equipment stops cleaning, which seriously affects the production continuity.

Detailed Implementation

[0023] With reference to the accompanying drawings: the technical solutions in the embodiments of the present application will be described clearly and completely, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of the present application.

[0024] In order to solve the technical problem that when the material near the blade is insufficient, the remaining stuffing in the conveying pipe 3 cannot be pushed with enough force, resulting in the accumulation of the stuffing in the conveying pipe 3, as shown in Figures 1-8 The following preferred technical solutions are provided: As shown in Figures 1-2 A stuffing conveying device for a dumpling machine, comprising a dumpling machine body 1 and a material bin 2 fixedly installed on one side of the dumpling machine body 1, one end of the material bin 2 being communicated with a conveying pipe 3, the material bin 2 being directly fixed on one side of the dumpling machine body 1, the conveying pipe 3 being communicated therebetween, shortening the stuffing conveying path, reducing the residual and loss of stuffing in the intermediate links, and avoiding the problems of stuffing accumulation or material breakage caused by the excessively long pipe in the traditional split layout, a driving seat 4 being installed inside the material bin 2, a housing 5 being fixedly installed on one side of the driving seat 4, an air pump 6 being installed on one side of the housing 5, a plurality of air inlet pipes 7 being communicated on the surface of the housing 5, the plurality of air inlet pipes 7 extending from the housing 5 to the inside of the material bin 2, the distribution of the plurality of air inlet pipes 7 being reasonably arranged according to the distribution of the accumulation area at the bottom of the material bin 2, so as to ensure that the accumulation points can be covered when the subsequent gas-assisted pushing is performed, and to avoid the local accumulation and residual caused by the uneven gas supply of a single air inlet pipe 7.

[0025] The inside of the bin 2 is provided with a guide plate 8, which is usually designed in an inclined structure and can guide the stuffing in the bin 2 to converge to the area of the hollow screw rod 20, so as to avoid the long-term accumulation of the stuffing at the edge of the bin 2, reduce the risk of accumulation from the source, and the plurality of air inlet pipes 7 are communicated with the guide plate 8, the guide plate 8 is internally provided with elastic push plates 9 corresponding to the air inlet pipes 7, the elastic push plates 9 correspond to the air inlet pipes 7 one by one, the airflow of each air inlet pipe 7 only drives the elastic push plate 9 in the corresponding area, so as to accurately force the accumulation points at different positions of the bottom of the bin 2, avoid the problem that the local accumulation cannot be removed, the inside of the shell 5 is rotationally connected with an annular through-hole plate 10, the driving seat 4 is provided with a hollow screw rod 20 on one side, and the hollow screw rod 20 is communicated with the shell 5, the inside of the hollow screw rod 20 is provided with an elastic push rod 30, the hollow screw rod 20 not only retains the extrusion conveying function of the traditional screw rod, but also provides an installation and movement channel for the elastic push rod 30 through the internal hollow design, so that it is not necessary to additionally add a pushing component in the conveying pipeline 3, the equipment structure is simplified, the cleaning dead angle is reduced, the elastic push rod 30 can move downward under the pushing of the gas, directly push the stagnant stuffing in the conveying pipeline 3, avoid the occurrence of the vicious cycle of material breakage and accumulation in the pipeline, and after the bin 2 is empty, the elastic push rod 30 can continuously push the material until the stuffing in the conveying pipeline 3 is completely conveyed, so as to realize the non-residual feeding, reduce the waste and deterioration risk of the stuffing.

[0026] The inside of the shell 5 is provided with a guide 40, the surface of the guide 40 is provided with a sealing seat 50, the sealing seat 50 is slidingly connected with the shell 5, the sealing seat 50 is drivingly connected with the annular through-hole plate 10, and the sealing seat 50 is in contact with one end of the hollow screw rod 20, the annular through-hole plate 10 can realize the switching between the communication with the air inlet pipe 7 and the dislocation with the air inlet pipe 7 through rotation, and in cooperation with the sliding of the sealing seat 50, the gas supply demand of the bin 2 when lacking material and the conveying pipeline 3 when having material can be met respectively, without manual adjustment of the gas circuit, so as to realize the automatic adaptation of the working condition.

[0027] Firstly, the driving seat 4 is started to drive the hollow screw rod 20 connected therewith to rotate, the helical blades of the hollow screw rod 20 generate an axial extrusion force on the stuffing in the bin 2, continuously push the stuffing along the helical channel to the bottom of the bin 2, and extrude the stuffing to the inlet of the conveying pipeline 3, at this time, the annular through-hole plate 10 in the shell 5 is in the initial position and is completely dislocated with the air inlet pipe 7, at the same time, the sealing seat 50 tightly fits the end of the hollow screw rod 20 under the limiting of the guide 40, and blocks the internal channel, the air pump 6 is not started temporarily, so as to ensure that the stuffing is conveyed only through the screw extrusion force, and avoid the interference of the gas with the normal feeding rhythm, when the bottom of the hollow screw rod 20 lacks material, the stuffing is accumulated in the bottom dead angle and the inlet of the conveying pipeline 3 due to the inclined characteristics of the bottom of the bin 2, the air pump 6 injects compressed gas into the inside of the shell 5, as the air pressure in the shell 5 gradually rises to the preset threshold value, the controller (the controller is prior art and not shown in the figure) triggers the guide 40 to start.

[0028] The guide 40 drives the sealing seat 50 to slide along the inner wall of the shell 5, and the sealing seat 50 synchronously drives the annular through-hole plate 10 to rotate synchronously until the annular through-hole plate 10 is completely aligned and communicated with the plurality of air inlet pipes 7, and at the same time, the sealing seat 50 is separated from the end of the hollow spiral rod 20 to release the blockage of the internal passage thereof. The compressed gas enters the plurality of air inlet pipes 7 through the through holes of the annular through-hole plate 10 and is injected into the inside of the guide plate 8 in a pulse air flow. The pulse air flow pushes the elastic push plate 9 in the guide plate 8 to move, and the plurality of elastic push plates 9 synchronously generate force to push the stuffing accumulated at the bottom of the material bin 2 to the spiral blade area of the hollow spiral rod 20, which is assisted by gravity due to the inclined design at the bottom of the material bin 2 to speed up the speed of the stuffing to the inlet of the conveying pipeline 3. At the same time, part of the pulse air flow enters the inside of the hollow spiral rod 20 to push the elastic push rod 30 to move downward along the axis of the hollow spiral rod 20. The end of the elastic push rod 30 directly contacts the stuffing in the conveying pipeline 3 to push the stuffing that is stalled due to insufficient spiral extrusion force downward by a distance to ensure that the stuffing in the conveying pipeline 3 continuously moves to the dumpling machine body 1 and avoid the occurrence of material breakage or accumulation in the conveying pipeline 3.

[0029] The indirect pushing of the elastic push plate 9 and the elastic push rod 30, together with the natural flow of the stuffing due to gravity, can better push the stuffing into the conveying pipeline 3. When there is still remaining stuffing in the conveying pipeline 3, the sealing seat 50 is reversely moved by the guide 40 to drive the annular through-hole plate 10 to rotate again so that the through holes of the annular through-hole plate 10 are misaligned with the air inlet pipes 7, thereby cutting off the gas supply to the guide plate 8. The continuous reverse movement of the sealing seat 50 can keep the end of the hollow spiral rod 20 open. The air pump 6 continuously injects gas into the shell 5, and the gas is only delivered through the internal passage of the hollow spiral rod 20. The continuous air flow pushes the elastic push rod 30 to move downward along the axis of the hollow spiral rod 20 at a constant speed. The end of the elastic push rod 30 is always in contact with the stuffing in the conveying pipeline 3 to continuously push the remaining stuffing in the conveying pipeline 3 to the dumpling machine body 1 with a stable pushing force until the stuffing in the pipeline is completely delivered, achieving no residual feeding and avoiding the deterioration of the stuffing due to long-term accumulation in the pipeline.

[0030] Therefore, through the cooperation of the air pump 6, the annular through-hole plate 10, the elastic push plate 9 and the elastic push rod 30, when there is insufficient material at the bottom of the hollow spiral rod 20, auxiliary power can be provided in time to speed up the speed of the stuffing to the inlet of the conveying pipeline 3. The elastic push rod 30 can relay the pushing of the material when the spiral extrusion force is insufficient, and continuously push the remaining stuffing in the conveying pipeline 3 after the material bin 2 is empty, thereby avoiding the occurrence of material breakage and accumulation in the conveying pipeline 3.

[0031] As Figures 3-6As shown, the surface of the bin 2 is fixedly provided with a support frame 21, and the support frame 21 is fixedly connected with the dumpling machine body 1, and the support frame 21 can support the bin 2 and improve the stability of the bin 2. The bin 2 is connected with a feeding shell 22 at one side, and the feeding shell 22 extends to the inside of the guide plate 8 at one end. The stuffing is placed in the feeding shell 22, so that the stuffing enters the inside of the bin 2.

[0032] The driving seat 4 includes a concave frame 41 and a shell 42 fixed on one side of the concave frame 41. The hollow screw rod 20 is rotatably connected with the concave frame 41 and the shell 42. The first motor 43 is fixedly installed in the shell 42. The first gear 44 is fixedly installed at the output end of the first motor 43. The shell 42 provides a closed and fixed installation space for the first motor 43, so that the stuffing debris, dust and other impurities cannot enter the inside of the first motor 43, and the motor failure is prevented. At the same time, the first motor 43 directly drives the hollow screw rod 20 through the first gear 44. The transmission path is short and the loss is small, so that the rotation speed of the hollow screw rod 20 is stable, and the problem of fast and slow conveying of the stuffing caused by unstable power transmission is avoided.

[0033] The concave plate 51 is fixedly installed in the shell 5. The pressure sensor 52 is also fixedly installed in the shell 5, and the pressure sensor 52 is electrically connected with the guide piece 40 through the controller. The pressure sensor 52 can monitor the pressure change in the shell 5 in real time, and replace the traditional timing or manual control mode. When the pressure in the shell 5 reaches the preset threshold value, the guide piece 40 can be accurately triggered to act, so that the timing of the communication between the annular through-hole plate 10 and the air inlet pipe 7 and the unblocking of the sealing seat 50 is just right, and the problems of insufficient auxiliary power caused by insufficient air pressure or component damage caused by excessive air pressure are avoided.

[0034] As shown in the figure, Figure 7 The elastic push plate 9 includes a first circular plate 91 and a first push rod 92 connected on one side of the first circular plate 91. The first push rod 92 is slidably connected with the inner wall of the guide plate 8. The first spring 93 is fixedly installed on one side of the first circular plate 91, and one end of the first spring 93 is fixedly connected with the first push rod 92. The first push rod 92 is fixedly installed with a push plate 94 at one end, and the push plate 94 is slidably connected with the guide plate 8. When the bin 2 is out of material at the bottom, the pulse gas delivered by the air pump 6 enters the guide plate 8, and the first push rod 92 and the push plate 94 of the elastic push plate 9 are moved, which can push the stuffing accumulated at the bottom of the bin 2 to the middle, speed up the flow speed of the stuffing, ensure the continuous supply of the stuffing, and avoid the problem of poor conveying caused by the accumulation and slow flow of the stuffing. When there is no pulse gas in the guide plate 8, the first push rod 92 and the push plate 94 can return to the initial position through the elastic force of the first spring 93, which is convenient for the next triggering.

[0035] As shown in the figure, Figure 5As shown, the surface of the annular through-hole plate 10 is provided with a gas outlet hole 101 corresponding to the air inlet pipe 7. The gas outlet hole 101 precisely corresponds to the air inlet pipe 7. Only when the annular through-hole plate 10 is rotated to a specific angle, the gas outlet hole 101 will communicate with the air inlet pipe 7, ensuring that the pulse gas delivered by the air pump 6 can accurately enter the material guide plate 8, avoiding the gas from entering too early or delaying, preventing waste of auxiliary power, and ensuring that the push plate 94 starts to push only when there is a lack of material, matching the conveying rhythm of the device. The annular through-hole plate 10 is fixedly installed with a limiting ring 102 on the surface, and the limiting ring 102 is rotationally connected with the shell 5. The limiting ring 102 limits the free rotation of the annular through-hole plate 10 through the friction force with the shell 5, so that it always maintains the initial state of being out of position with the air inlet pipe 7 when not driven by power, effectively blocking the air inlet pipe 7 to prevent gas leakage during normal conveying, ensuring that the air pump 6 can quickly increase the pressure in the shell 5 to accumulate enough power for pulse gas supply when there is a lack of material. The annular through-hole plate 10 is fixedly installed with a rotating plate 103 on one side, and the rotating plate 103 is rotationally connected with the concave plate 51. One end of the rotating plate 103 is fixed with the annular through-hole plate 10, and the other end is rotationally connected with the concave plate 51, forming a double support structure that disperses the rotating stress of the annular through-hole plate 10, avoiding deformation of the components due to excessive unilateral stress after long-term operation, prolonging the service life of the annular through-hole plate 10. The rotating plate 103 is fixedly installed with a support column 104 on one side, and the support column 104 is fixedly installed with a second gear 105 on one end.

[0036] As shown in Figure 4 The hollow spiral rod 20 is fixedly installed with a third gear 201 on the surface, and the first gear 44 is meshingly connected with the third gear 201. The first gear 44 is meshingly connected with the third gear 201, forming a direct transmission path from the first motor 43 to the hollow spiral rod 20. The meshing transmission has the characteristics of precise transmission ratio and small power loss, which can stably transmit the torque of the first motor 43 to the hollow spiral rod 20, ensuring uniform speed and avoiding the problem of fast and slow filling material conveying caused by unstable power transmission, ensuring the continuous extrusion force of the spiral blade on the filling material, reducing the risk of filling material stagnation and accumulation in the conveying pipeline 3. One end of the hollow spiral rod 20 is rotationally connected with an annular plate 202, and the annular plate 202 is fixedly connected with the shell 5. First, the compressed gas enters the inside of the hollow spiral rod 20 through the annular plate 202, which can ensure the stability of the gas entering the inside of the hollow spiral rod 20.

[0037] As shown in Figure 6As shown, the guide 40 includes a support plate 401 and a second motor 402 fixed inside the support plate 401, a vertical plate 403 is fixedly installed inside the shell 5, a threaded rod 404 is fixedly installed at the output end of the second motor 402, and the threaded rod 404 is rotatably connected with the vertical plate 403. The second motor 402 drives the threaded rod 404 to rotate, and the threaded rod 404 can convert the rotary motion of the motor into the linear motion of the sealing seat 50. This screw transmission mode has the characteristics of high displacement accuracy and controllable speed, and can accurately control the moving distance and speed of the sealing seat 50, ensuring the position accuracy when switching between the two states of plugging and unplugging the hollow spiral rod 20, avoiding gas leakage or incomplete air flow conduction caused by displacement deviation, and combining the signal of the pressure sensor 52. The second motor 402 can accurately start or stop according to the change of the air pressure in the shell 5, so that the action of the sealing seat 50 is completely synchronized with the air pressure threshold. For example, when the air pressure reaches the threshold, the second motor 402 immediately drives the threaded rod 404 to move the sealing seat 50, ensuring that the annular through-hole plate 10 is timely connected to the air inlet pipe 7, so that the pulse gas can accurately act on the elastic push plate 9 and the elastic push rod 30.

[0038] The sealing seat 50 includes a sealing plate 501 and a sliding block 502 fixed on both sides of the sealing plate 501. The sealing plate 501 is threadedly connected with the threaded rod 404, and the rotary motion of the threaded rod 404 can be accurately converted into the linear motion of the sealing plate 501. This transmission mode has no risk of slipping, and can ensure the position accuracy of the sealing plate 501 when plugging and unplugging the hollow spiral rod 20, avoiding gas leakage in the shell 5 or incomplete air flow conduction due to displacement deviation. The sliding block 502 is slidably connected with the concave plate 51, and the sealing plate 501 is fixedly installed with a toothed plate 503 on the side close to the second gear 105. When the sealing plate 501 moves, the toothed plate 503 can drive the second gear 105 to rotate, and then drive the annular through-hole plate 10 to rotate through the support 104 and the rotating plate 103. This linkage design allows the sealing plate 501 to move and the annular through-hole plate 10 to connect the air inlet pipe 7 to be performed synchronously, without the need for an additional power source. This simplifies the structure while ensuring that the air flow control and sealing switching are completely coordinated, avoiding the failure of auxiliary delivery caused by action delay. In the initial state, the toothed plate 503 is not engaged with the second gear 105, and the reverse movement of the sealing plate 501 will not drive the second gear 105 and the annular through-hole plate 10 to rotate, so only the hollow spiral rod 20 is released, allowing the gas to be continuously delivered to the inside of the hollow spiral rod 20, and the filling inside the delivery pipeline 3 can be continuously pushed.

[0039] In order to solve the technical problem that the filling easily seeps into the inner wall of the delivery pipeline 3 from the gap when the inner wall of the delivery pipeline 3 is worn, Figure 4 and Figure 8 As shown, the following preferred technical solutions are provided: The elastic push rod 30 comprises a second circular plate 301 and a second push rod 302 connected to one side of the second circular plate 301, the second push rod 302 is in sliding connection with the inner wall of the hollow spiral rod 20, the second circular plate 301 is fixedly installed on one side and the second spring 303 is fixedly connected with one end of the second push rod 302, the second push rod 302 is fixedly installed on one end and the push column 304 is fixedly installed on one end, the pulse gas delivered by the air pump 6 enters the inside of the hollow spiral rod 20, the second push rod 302 and the push column 304 are pushed to move, the stuffing accumulated at the bottom of the stock bin 2 can be pushed into the conveying pipeline 3, the continuous supply of the stuffing is ensured, and the problem of poor conveying caused by the accumulation and slow flow of the stuffing is avoided, when there is no pulse gas in the inside of the hollow spiral rod 20, the second push rod 302 and the push column 304 can return to the initial position through the elastic force of the second spring 303, and the next triggering is facilitated.
