A stuffing device

Abstract

This invention relates to the field of food production equipment technology and discloses a filling device, including a machine base, a conveying mechanism, a rolling mechanism, a filling feeding mechanism, and an oiling mechanism. The oiling mechanism includes a first support plate, an oil storage tank vertically mounted on the first support plate, a brush body located downstream of the oil storage tank, and a clamping mechanism fixedly connected to the first support plate; the upper part of the brush body is clamped on the clamping mechanism. By setting up the oiling mechanism, after the dough is rolled into a roll by the rolling mechanism and filled, the dough with filling is moved by the conveying mechanism to the area below the oil storage tank, receiving the edible oil dripping from the oil outlet pipe. This allows the edible oil to be evenly applied to the surface of the dough by the brush body, effectively preventing the dough from sticking to the equipment, reducing dough friction damage and cracking, and ensuring a continuous and stable oiling process by storing a sufficient amount of edible oil in the oil storage tank at once, eliminating the need for frequent oil replenishment.

Description

Technical Field

[0001] This invention relates to the field of food production equipment technology, and in particular to a filling device. Background Technology

[0002] A filling device is a piece of equipment used in food processing (such as pastries and mooncakes) to wrap fillings inside dough, completing operations such as quantitative filling supply, rolling, and covering. Existing filling devices typically include a machine base, a conveying mechanism mounted on the machine base, a rolling mechanism mounted on the conveying mechanism, and a filling feeding mechanism. To prevent the dough from sticking to the equipment after filling and to reduce dough breakage and leakage, it is often necessary to coat the surface of the filled dough with oil. Current technology generally involves applying edible oil to the dough surface using a towel soaked in edible oil. However, this method requires workers to frequently refill the towel with oil, which is not only cumbersome but also prone to being overlooked due to other production activities. This can lead to insufficient oil supply to the towel, incomplete oiling of the dough surface, and consequently, dough sticking to the equipment, friction damage, and dough cracking and leakage.

[0003] It is evident that existing technologies need improvement and enhancement. Summary of the Invention

[0007] In the filling device, a first portal-shaped support is provided across the conveying mechanism on the machine platform; the top of the first portal-shaped support is provided with a strip-shaped through hole along the width direction of the conveying mechanism; the bottom of the first support plate is provided with a slider that cooperates with the strip-shaped through hole, and the first support plate is magnetically attracted to the top of the first portal-shaped support.

[0008] In the filling device, the top of the first gate-shaped bracket is also provided with a through-beam photoelectric sensor; the through-beam photoelectric sensor is electrically connected to a controller, and the through-beam photoelectric sensor includes a transmitter and a receiver; the controller is electrically connected to an alarm; transparent observation windows are respectively embedded on both sides of the lower part of the oil storage tank, and the two transparent observation windows are respectively arranged opposite to the transmitter and receiver.

[0009] In the filling device, the rolling mechanism includes a second portal frame that is inclined at an angle to the conveying direction of the conveying mechanism, a dough roll roller that is rotatably mounted on the second portal frame, a first drive mechanism connected to the second portal frame, a transmission mechanism located between the first drive mechanism and the dough roll roller, a first connecting seat fixed on the second portal frame and located above the dough roll roller, a second screw that is horizontally inserted through the first connecting seat, a second support plate that is vertically mounted on the machine base and used to support the second screw, a first adjusting handwheel fixed to one end of the second screw, and guide rods located on both sides of the second screw and horizontally inserted through the first connecting seat; The dough roll is used to roll the dough laid flat on the conveying mechanism into an oblique hollow roll; the first connecting seat is provided with a threaded hole; the second screw is threaded to the inner wall of the threaded hole; the two ends of the guide rod are respectively fixedly connected to two second support plates.

[0010] In the filling device, the filling feeding mechanism includes a first support platform next to the machine base, a round bucket vertical extruder on the first support platform, an extrusion nozzle at the extrusion port of the round bucket vertical extruder, a weighing sensor at the bottom of the round bucket vertical extruder and located on the machine base, and a weight display on the machine base; the extrusion nozzle is arranged facing the hollow dough roll.

[0011] In the filling device, two sets of guide components are also provided above the conveying mechanism; the two sets of guide components are arranged in a direction parallel to the length direction of the conveying mechanism, and the guide components are located between the rolling mechanism and the oiling mechanism; the guide components include a strip mounting plate and guide rollers that are vertically arranged and spaced apart on the strip mounting plate; A boom is fixed above the conveying mechanism along its width; a connector is movably sleeved on the boom; the connector is fixedly connected to a strip mounting plate, and a fastening screw that abuts against the boom is inserted into the connector.

[0012] The filling device further includes a cutting mechanism; the cutting mechanism is located downstream of the oiling mechanism, and the cutting mechanism includes a second support platform horizontally fixed above the conveying mechanism, a third support plate movably mounted on the second support platform along the width direction of the conveying mechanism, a cylinder mounted on the third support plate, a cutter located below the third support plate and connected to the cylinder extension rod, a guide rail mounted on the second support platform for guiding the third support plate, and an adjustment mechanism for driving the third support plate to move.

[0015] Beneficial effects: This invention provides a filling-wrapping device. An oil-coating mechanism, consisting of an oil storage tank, a brush, a first support plate, and a clamping mechanism, is installed above a conveying mechanism downstream of a rolling mechanism. After the dough is rolled into a roll and filled, the dough with filling is conveyed by the rolling mechanism to a position below the oil storage tank, where it receives edible oil dripping from the oil outlet. This allows the edible oil to be evenly coated onto the surface of the dough through the brush, effectively preventing the dough from sticking to the equipment and reducing dough friction damage, cracking, and leakage. Furthermore, the oil storage tank can store a sufficient amount of edible oil at once, eliminating the need for frequent oil replenishment and ensuring a continuous and stable oil-coating process.

This ensures that the oil dripping and brushing actions correspond to the dough conveying trajectory, thereby avoiding uneven oiling caused by the oiling position shift. At the same time, the brush body is stably clamped by the clamping mechanism and is not easy to shake, which can further improve the uniformity and reliability of oiling. Attached Figure Description

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0034] Please see Figures 1 to 11 The present invention provides a filling device for wrapping filling inside dough and has the function of conveying the dough containing filling to a forming device (not shown in the figure) for forming (e.g., forming into the shape of a pastry).

[0035] Specifically, the filling device includes a machine base 1 and a conveying mechanism 2. Figure 1 The arrows indicate the conveying direction of the conveying mechanism 2, the rolling mechanism 3, the filling feeding mechanism 4, and the oiling mechanism 5. The conveying mechanism 2 is arranged along the length of the machine platform 1 and is equipped with a motor-driven conveyor belt to transport dough sheets. The dough sheets are then wrapped with filling by the filling device, and the filled dough is conveyed to the forming device for shaping. The rolling mechanism 3 is located on the conveying mechanism 2 and is inclined at a certain angle to the conveying direction of the conveying mechanism 2, allowing it to roll the dough sheets laid flat on the conveying mechanism 2 into hollow rolls. The filling feeding mechanism 4 is located beside the machine platform 1 and works with the rolling mechanism 3 to feed the filling into the hollow dough roll, thus realizing the filling operation.

[0036] In order to coat the surface of the dough containing the filling with oil, the oiling mechanism 5 is mounted above the conveying mechanism 2 and is located downstream of the rolling mechanism 3.

[0037] Specifically, the oil coating mechanism 5 includes a first support plate 51 horizontally fixed above the conveying mechanism 2, an oil storage tank 52 vertically mounted on the first support plate 51, an oil outlet pipe 53 located at the bottom of the oil storage tank 52 and extending downward through the first support plate 51, an oil outlet control valve 54 mounted on the oil outlet pipe 53, a brush body 55 located downstream of the oil storage tank 52, and a clamping mechanism 56 fixedly connected to the first support plate 51 and used to clamp the upper part of the brush body 55.

[0038] After the dough is rolled into a roll by the rolling mechanism 3 and filled, the dough with filling is moved to the bottom of the oil storage tank 52 by the conveying mechanism 2. At this time, the edible oil in the oil storage tank 52 drips down onto the surface of the strip-shaped dough through the oil outlet pipe 53. Then, the surface of the dough is evenly coated by the brush body 55 located downstream of the oil storage tank 52, so that the edible oil is evenly covered on the surface of the dough. This can effectively prevent the dough from sticking to the equipment, reduce the occurrence of dough friction damage and cracking leakage. In addition, the oil storage tank 52 can store a sufficient amount of edible oil at one time, so that there is no need to frequently replenish the oil, ensuring a continuous and stable oiling process.

[0039] Furthermore, the present invention clamps the upper part of the brush body 55 with the clamping mechanism 56, and the clamping mechanism 56 is fixedly connected to the first support plate 51, so that the oil dripping positions of the brush body 55 and the oil outlet pipe 53 can be on the movement path of the dough. This ensures that the oil dripping and brushing action correspond to the dough conveying trajectory, thereby avoiding uneven oiling caused by the oiling position shift. At the same time, the brush body 55 is stably clamped by the clamping mechanism 56 and is not easy to shake, which can further improve the uniformity and reliability of oiling.

[0040] like Figures 2 to 5 As shown, in a preferred embodiment, the clamping mechanism 56 includes multiple L-shaped support frames 561 fixedly mounted on the first support plate 51, a first screw 562 horizontally penetrating and fixedly mounted on the L-shaped support frames 561, a first clamping plate 563 vertically and fixedly sleeved on the first screw 562, a second clamping plate 564 vertically and fixedly sleeved on the first screw 562, and a limiting nut 565 sleeved on the first screw 562 and abutting against both sides of the second clamping plate 564. In this embodiment, by sleeved the first clamping plate 563 and the second clamping plate 564 on the first screw 562 and cooperating with the limiting nut 565, the distance between the first clamping plate 563 and the second clamping plate 564 can be flexibly adjusted, thereby adapting to and clamping brush bodies 55 of different specifications, thus meeting the usage requirements of different oiling widths and different bristle 552 sizes. At the same time, when the limiting nut 565 loosens its contact with the second clamping plate 564, the clamping position of the upper part of the brush body 55 can be adjusted at will, thereby ensuring that the oil dripping positions of the brush body 55 and the oil outlet pipe 53 are both on the movement path of the dough, which helps to improve the uniformity of oil coating.

[0041] like Figure 4 and Figure 5As shown, in a preferred embodiment, the brush body 55 includes an inverted T-shaped handle 551 and bristles 552 fixedly disposed at the bottom of the handle 551; the upper part of the handle 551 is clamped between a first clamping plate 563 and a second clamping plate 564. Using an inverted T-shaped handle 551 allows for flexible adjustment of the clamping height of the handle 551 in the vertical direction, thus adjusting the distance between the bristles 552 and the dough. This adapts to the oiling requirements of doughs of different thicknesses and allows for adjustment of the brushing force according to production conditions, ensuring even and thorough oiling.

[0042] As an example, the bristles 552 can be strip bristles 552 or curved bristles 552 adapted to the shape of the dough. Curved bristles 552 can conform to the outer contour of the dough, further improving the integrity of the oil coating.

[0043] like Figures 1 to 4 As shown, in a preferred embodiment, a first portal frame 6 is provided across the conveying mechanism 2 on the machine base 1; the top of the first portal frame 6 has a strip-shaped through hole 61 along the width direction of the conveying mechanism 2; the bottom of the first support plate 51 has a slider 57 that cooperates with the strip-shaped through hole 61, and the first support plate 51 is magnetically attached to the top of the first portal frame 6. In this embodiment, the strip-shaped through hole 61, in conjunction with the slider 57 at the bottom of the first support plate 51, can limit the position of the oil storage tank 52 and the brush body 55, so that the oil storage tank 52 and the brush body 55 can only be adjusted in position along the width direction of the conveying mechanism 2, thereby ensuring that the oil dripping positions of the brush body 55 and the oil outlet pipe 53 are both on the movement path of the dough. When the first support plate 51 is magnetically attached to the top of the first portal frame 6, the oil storage tank 52 and the brush body 55 can be moved without tools, facilitating the adjustment of the position of the oil storage tank 52 and the brush body 55.

[0044] For example, the first support plate 51 can be fixed to the first portal frame 6 using a magnetic base. The first portal frame 6 can be a stainless steel bracket.

[0045] like Figure 3 , Figure 4 as well as Figure 6 As shown, in a preferred embodiment, the top of the first portal frame 6 is also provided with a through-beam photoelectric sensor; the through-beam photoelectric sensor is electrically connected to a controller, and the through-beam photoelectric sensor includes a transmitter 7 and a receiver 8; the controller is electrically connected to an alarm; transparent observation windows 9 are respectively embedded on both sides of the lower part of the oil storage tank 52, and the two transparent observation windows 9 are respectively arranged opposite to the transmitter 7 and the receiver 8.

[0046] When the through-beam photoelectric sensor is working, the light emitted from its transmitter 7 is directed to the receiver 8 through the transparent observation window 9. When the oil level in the oil storage tank 52 is normal and submerges the transparent observation window 9, the light passing through the edible oil will be refracted and attenuated, and the receiver 8 cannot receive stable light. When the oil level drops below the transparent observation window 9, the light can pass directly through the air to form a stable light path, and the receiver 8 receives the light signal. At this time, the sensor outputs an electrical signal to the controller, which drives the alarm to remind the staff to add oil in an audible and visual manner. This achieves automatic early warning for low oil levels, avoids interruption of oiling due to lack of oil, ensures continuous and stable oiling, and prevents dough from sticking to the equipment, causing friction damage, and preventing leakage.

[0047] like Figure 9 As shown, in a preferred embodiment, the roll material mechanism 3 includes a second portal frame 301 inclined at an angle to the conveying direction of the conveying mechanism 2, a sheet roll 302 rotatably mounted on the second portal frame 301, a first drive mechanism 303 connected to the second portal frame 301, a transmission mechanism 304 disposed between the first drive mechanism 303 and the sheet roll 302, a first connecting seat 305 fixed on the second portal frame 301 and located above the sheet roll 302, a second screw 306 horizontally passing through the first connecting seat 305, a second support plate 307 vertically mounted on the machine base 1 for supporting the second screw 306, a first adjusting handwheel 308 fixedly mounted on one end of the second screw 306, and guide rods 309 located on both sides of the second screw 306 and horizontally passing through the first connecting seat 305. The two ends of the guide rods 309 are respectively fixedly connected to two second support plates 307.

[0048] Specifically, the two ends of the dough roll 302 are rotatably connected to the two sides of the second portal frame 301. The first drive mechanism 303 can be a drive motor. Under the drive of the drive motor, the dough roll 302 can rotate counterclockwise, thereby cooperating with the conveying mechanism 2 to roll the dough laid flat on the conveying mechanism 2 into an oblique hollow roll. In order to transmit the power of the drive motor to the dough roll 302, the transmission mechanism 304 can be a chain drive mechanism 304 or a belt drive mechanism 304. It can be understood that when the transmission mechanism 304 is the above-mentioned mechanism, the drive wheel is coaxially arranged with the output shaft of the drive motor, and the driven wheel is coaxially arranged with the dough roll 302.

[0049] Specifically, the first connecting seat 305 is provided with a threaded hole. The second screw 306 is threadedly connected to the inner wall of the threaded hole, and the second screw 306 is rotatably connected to the second support plate 307. Since the first adjusting handwheel 308 is fixed at least at one end of the second screw 306, rotating the first adjusting handwheel 308 can drive the second screw 306 to rotate; when the second screw 306 rotates, it can drive the first connecting seat 305 and the second portal bracket 301 to move horizontally along the guide rod 309, thereby realizing the adjustment of the position of the dough roll roller 302, ensuring that the dough roll roller 302 can roll the dough into the required roll shape.

[0050] like Figure 7 As shown, in a preferred embodiment, the filling feeding mechanism 4 includes a first support platform 401 located beside the machine base 1, a cylindrical vertical extruder 402 mounted on the first support platform 401, an extrusion nozzle 403 located at the extrusion opening of the cylindrical vertical extruder 402, a weighing sensor 404 located at the bottom of the cylindrical vertical extruder 402 and on the machine base 1, and a weight display 405 located on the machine base 1; the extrusion nozzle 403 is arranged facing the hollow surface. In this embodiment, the weighing sensor 404 can monitor the weight change of the filling inside the cylindrical vertical extruder 402 in real time, and the weight display 405 can intuitively display the amount of filling used, thereby facilitating workers to promptly grasp the filling consumption and accurately determine whether filling needs to be replenished.

[0051] like Figure 1 and Figure 10 As shown, in a preferred embodiment, two sets of guide components 10 are further provided above the conveying mechanism 2; the two sets of guide components 10 are arranged in a direction parallel to the length direction of the conveying mechanism 2, and the guide components 10 are located between the winding mechanism 3 and the oiling mechanism 5; the guide component 10 includes a strip mounting plate 101 and guide rollers 102 arranged vertically and spaced apart on the strip mounting plate 101. In this embodiment, by setting the guide component 10 between the winding mechanism 3 and the oiling mechanism 5, the guide rollers 102 on the guide component 10 can stably guide and limit the strip-shaped dough, preventing the dough from deviating, tilting or scattering during the conveying process, ensuring that the dough is always conveyed smoothly along the preset path, so that the dough can pass correctly below the oil outlet pipe 53 and below the brush body 55, thereby ensuring accurate oiling position, uniform and complete oiling, and preventing local missed coating or insufficient oiling due to dough deviation.

[0052] like Figure 10As shown, further, a hanging rod 11 is fixed above the conveying mechanism 2 along its width direction. The hanging rod 11 can be a square rod or a round rod, and a connecting member 12 is movably sleeved on the hanging rod 11. The connecting member 12 is fixedly connected to the strip mounting plate 101, and a fastening screw 16 that abuts against the hanging rod 11 is inserted into the connecting member 12. By moving the connecting member 12 along the length direction of the hanging rod 11, the worker can adjust the position of the strip mounting plate 101, thereby enabling flexible adjustment of the spacing of the guide components 10. This allows for adaptation to the guiding needs of dough of different widths and specifications, increasing the flexibility of the device. After adjusting the spacing of the guide components 10, the connecting member 12 can be quickly locked by the fastening screw 16, ensuring that the guide components 10 are fixed and do not loosen.

[0053] like Figure 1 , Figure 7 as well as Figure 11 As shown, in a preferred embodiment, the filling device further includes a cutting mechanism 13. The cutting mechanism 13 is located downstream of the oiling mechanism 5, and includes a second support platform 131 horizontally fixed above the conveying mechanism 2, a third support plate 132 movably mounted on the second support platform 131 along the width direction of the conveying mechanism 2, a cylinder 133 mounted on the third support plate 132, a cutter 134 located below the third support plate 132 and connected to the telescopic rod of the cylinder 133, a guide rail 135 mounted on the second support platform 131 for guiding the third support plate 132, and an adjustment mechanism 136 for driving the third support plate 132 to move. In this embodiment, by setting the cutting mechanism 13 downstream of the oiling mechanism 5, the filled dough after oiling can be cut into fixed-length segments, realizing continuous automated cutting operations. Furthermore, by setting the cutting mechanism 13 downstream of the oiling mechanism 5 rather than upstream, the brush bristles 552 of the brush body 55 can be prevented from being introduced into the filling, ensuring that the filling is pure and free of impurities.

[0054] In conjunction with the adjustment mechanism 136, the third support plate 132, on which the cylinder 133 is installed, can move along the width direction of the conveying mechanism 2, thereby adjusting the position of the cutter 134 based on the conveying path of the dough. This ensures that the dough can be correctly cut, while also meeting the cutting requirements of dough of different specifications and widths.

[0055] As an example, the adjustment mechanism 136 may include a second connecting seat 1361 fixed to the bottom of the third support plate 132, a third screw 1362 connected to a threaded hole on the second connecting seat 1361, and a second adjustment handwheel 1363 fixedly disposed at least at one end of the third screw 1362. The principle by which the adjustment mechanism 136 drives the third support plate 132 is the same as the principle by which the second screw 306 rotates and transmits power to the first connecting seat 305.

[0056] like Figure 11 As shown, in a preferred embodiment, a first protective railing 14 is fixed above the conveying mechanism 2 next to the cutter 134. The first protective railing 14 can effectively prevent operators from direct contact with the cutter 134, preventing accidents such as accidental contact and hand injuries during production.

[0057] like Figure 2 , Figure 7 as well as Figure 8 As shown, in a preferred embodiment, the filling device further includes a dough pressing mechanism 15; the dough pressing mechanism 15 includes a first dough pressing roller 151 and a second dough pressing roller 152 rotatably disposed above the conveying mechanism 2, a second drive mechanism 153 pulvinctly connected to the first dough pressing roller 151 or the second dough pressing roller 152, a support base 154 for supporting the first dough pressing roller 151 and the second dough pressing roller 152, and a second protective railing 155 erected on the support base 154. The first dough pressing roller 151 is located directly above the second dough pressing roller 152. The second drive mechanism 153 may also be a drive motor.

[0058] In the dough pressing mechanism 15, when the second drive mechanism 153 is working, the first pressing roller 151 and the second pressing roller 152 perform a rolling pressing motion, thereby uniformly pressing the dough, making the dough of consistent thickness and with a smooth surface, which facilitates subsequent rolling, filling, and oiling operations, and improves the forming quality of the dough. The second protective railing 155 can isolate the rotating pressing rollers to prevent operators from accidentally touching and getting injured, and can also prevent debris from falling between the pressing rollers, thus improving the safety of equipment use and ensuring continuous and reliable dough pressing operations.

[0059] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
