Description

Technical Field

[0001] The invention relates to a material dropping device. Background Art

[0002] In the catering industry, especially in the field of automatic vending or automatic cooking, auxiliary materials and vegetables are often automatically packaged into containers (such as bowls). In particular, cooked meat (beef brisket) is often in block shape. Due to the presence of soup, each piece of beef brisket sticks to each other, and the shapes and sizes of each piece of beef brisket are not consistent.

[0003] There is no effective device for automatically dispensing cooked meat (beef brisket) into containers (bowls) in the prior art, which seriously restricts the development of the field of automatic catering vending and automatic cooking. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a blanking device.

[0005] The material dropping device of the present invention comprises a material bladder including a material cavity, a material shifting plate, and a spiral conveying device;

[0006] The partition separates the material chamber into a material holding chamber and a material distribution chamber, and a material transfer gap D is set between the material holding chamber and the material distribution chamber; the screw conveying device is installed in the material distribution chamber, and the material shifting plate is rotatably installed in the material transfer gap D and separates the material holding chamber and the material distribution chamber; after the material shifting plate rotates and flips the material in the material holding chamber and falls into the screw conveying device in the material distribution chamber, the material is sent out by the screw conveying device.

[0007] When in use, materials (meat chunks, beef brisket) are placed in the material holding chamber. Since the material shifting plate is located at the material passing gap, the material shifting plate can block the materials in the material holding chamber when the material shifting plate is stationary and not rotating, to prevent the materials from entering the material distribution chamber. When the materials need to be delivered, the material shifting plate is driven to rotate, and the material shifting plate shifts the materials in the material holding chamber into the material distribution chamber. The materials entering the material distribution chamber fall onto the screw conveying device, and are finally delivered out of the material distribution chamber via the screw conveying device.

[0008] The material shifting plate is located between the material holding chamber and the material dividing chamber, and its rotating shaft drives the material shifting plate to flip so as to shift the material in the material holding chamber into the material dividing chamber, and then the spiral conveying device performs secondary material division and conveys the material out; the material shifting plate of the present technical solution can shift a small amount of irregular and mutually adhering materials (meat chunks, etc.) in the material holding chamber into the material dividing chamber, and finally the spiral conveying device performs secondary separation and drops the materials, that is, it can automatically separate a pile of disordered and mutually adhering materials (meat chunks, etc.) into an appropriate amount of materials (meat chunks, etc.), so as to better achieve the purpose of automatic quantitative material taking, meet the requirements of automatic quantitative addition of auxiliary materials and vegetables in the field of automatic catering vending and automatic cooking, and ultimately promote the development of the field of automatic catering vending and automatic cooking.

[0009] In some specific embodiments, it also includes a power device and a side plate for driving the material shifting plate to rotate; the partition plate, the material shifting plate, the side plate and the power device constitute a material shifting assembly, and the material shifting assembly can be detachably installed in the material cavity; when the material shifting assembly is installed in the material cavity, the partition plate, the side plate and the inner wall of the material cavity together form a material holding cavity.

[0010] In view of the scenarios in which the technology of the present invention is used, it often needs to be cleaned after use. The material shifting assembly of the present technical solution is made into a detachable structure. After using the material dropping device, the entire material shifting assembly can be directly taken out, and then the material chamber and the material holding chamber are connected to form a material bladder. When cleaning, the material bladder and the material shifting assembly can be cleaned separately. It can be cleaned without dead corners, ensuring hygiene. Especially in the catering industry, this design can reduce the difficulty of cleaning for staff.

[0011] In some specific embodiments, the outer wall of the material distribution chamber extends outward from the material discharging chamber, and an opening is arranged at the end of the extending portion of the material distribution chamber, and a downward-facing discharge port is arranged on the bottom wall of the extending portion of the material distribution chamber, and the screw conveying device is detachably installed in the material distribution chamber through the opening; the screw conveying device conveys materials, and the materials fall when they are conveyed to the discharge port.

[0012] The spiral conveying device is designed as a detachable structure. When cleaning, the spiral conveying device can be disassembled and cleaned to ensure that the blanking device is clean and hygienic after use to prevent bacteria from breeding.

[0013] In some specific embodiments, a fixed plate is provided at one end of the screw conveying device, and a matching hole is provided at the other end of the screw conveying device; a rotating shaft matching with the matching hole is provided at the other end of the material distribution chamber opposite to the opening; when installing the screw conveying device, the screw conveying device is extended into the material distribution chamber through the opening at the end of the material distribution chamber, so that the rotating shaft is inserted into the matching hole, at this time, the fixed plate is abutted against the open end of the material distribution chamber, and the fixed plate is fixed to the end of the material distribution chamber with screws.

[0014] After the matching hole of the screw conveying device and the rotating shaft match, the rotation of the screw conveying device is driven by the rotating shaft to achieve the purpose of conveying materials (the rotating shaft can be driven by a motor installed on the outer wall of the material bladder).

[0015] In some specific embodiments, the power device includes a rack, a cylinder installed on the material diverting assembly and used to drive the rack to move, a gear meshing with the rack, and a one-way bearing; the one-way bearing is installed on a rotating shaft, and the gear is installed on the one-way bearing; the rack drives the gear to rotate in the forward direction, and the rotating shaft drives the material diverting plate to rotate from the material holding chamber to the material distributing chamber, so as to divert the material in the material holding chamber into the material distributing chamber; the rack drives the gear to rotate in the reverse direction, and the gear rotates alone.

[0016] The one-way bearing is a bearing that can rotate freely in one direction and is locked in the other direction. Here, the positive rotation of the rack-driven gear is the rotation of the one-way bearing in the locked direction, and the bearing does not rotate in this rotation direction. It can be understood that the bearing and the rotating shaft are integrated, that is, the rotation of the gear-driven bearing drives the rotating shaft to rotate, thereby driving the material stripping plate to rotate, so as to transport the material from the material holding chamber to the material distribution chamber; on the contrary, the reverse rotation of the rack-driven gear is the free rotation of the one-way bearing in one direction, in which direction, the one-way bearing can rotate freely on the rotating shaft (which can be understood as the rotating shaft of the material stripping plate), that is, the rack moves in the opposite direction (this movement can be understood as the movement of the rack returning to its initial position in the forward movement), and the reverse movement of the rack drives the rotation of the gear, and the gear drives the bearing to rotate freely, that is, in this process, the bearing rotates freely relative to the rotating shaft, and the rotation of the bearing cannot drive the rotating shaft to rotate at the same time. At this time, the rotating shaft cannot drive the material stripping plate to rotate, and the material stripping plate does not strip the material from the material holding chamber to the material distribution chamber.

[0017] The above design, on the one hand, can ensure the continuous unidirectional rotation of the material plate from the material holding chamber to the material distribution chamber, and on the other hand, can be designed for intermittent rotation of the material plate. Each time the material plate rotates, a specific amount of material is conveyed into the material distribution chamber. The specific amount can be determined by the diameter of the material plate and the size of the space formed by each material plate.

[0018] In some specific embodiments, an adjustment plate is further included, and the adjustment plate is installed on the partition plate; the height of the adjustment plate is adjustable to adjust the size of the material passing gap D.

[0019] In some specific embodiments, it also includes a heat-insulating layer and a heating chamber; the heating chamber is in close contact with the outer wall of the material bladder, and the heat-insulating layer is in close contact with the outer wall of the heating chamber.

[0020] When in use, a certain amount of water is injected into the heating chamber, and then the water can be heated by heating elements such as electric heating wires and steam pipes. The heated water can be insulated by the insulation layer to reduce heat diffusion. In this way, the materials (meat and vegetables) in the material cavity in the material tank can be insulated.

[0021] In some specific embodiments, the material distribution chamber is provided with sieve holes and conduits connected to the sieve holes; the sieve holes are located at the bottom of the material distribution chamber at the extended portion.

[0022] Meat and vegetable materials often contain liquids such as soup. When the meat and vegetables are transported by the spiral conveyor, the meat and vegetables first pass through the sieve holes, so that the soup leaks through the sieve holes and enters the conduit for discharge. Then the meat and vegetables are transported to the discharge port and discharged through the discharge port. On the other hand, when the material dropping device of the present invention is cleaned, the water flushed from the material chamber can flow through the sieve holes.

[0023] In some specific embodiments, it further includes a base, a spring, and a vibrator;

[0024] The vibrator is installed on the material liner, one end of the spring is connected to the base, and the other end of the spring is connected to the material liner; the bottom of the material holding cavity is an inclined plate, and the bottom end of the inclined plate borders the material distribution cavity.

[0025] The vibrator vibrates, thereby driving the material bladder to shake, causing the material in the material holding chamber to slide toward the bottom along the inclined plate, and thus cling to the material stripping plate waiting for the rotation of the material stripping plate. Finally, the rotation of the material stripping plate will flip the material clinging to the material stripping plate and divert it into the material distribution chamber. In this way, the cyclic vibration can ensure that the material in the material holding chamber keeps sliding down and clinging to the material stripping plate, and the material stripping plate can block the material to prevent it from falling directly into the material distribution chamber. Finally, the material stripping plate can be rotated as needed to divert the material in the material holding chamber into the material distribution chamber, waiting for the spiral conveying device to separate and convey the material again. In addition, when the present blanking device is installed on an auxiliary machine (or other table top) for use, the base is fixed on the machine. Since the base and the material bladder are separated by a spring, the base can reduce the impact of the vibration of the vibrator and the vibration of the entire machine.

[0026] In some specific embodiments, a weight metering module is also included, which includes a material bowl, a flip cylinder, a weight detector and a rocker arm; the rocker arm is installed on the flip cylinder, the weight detector is installed on the rocker arm, and the material bowl is installed on the weight detector, and the material bowl is used to hold materials conveyed from the screw conveying device; wherein the material is block meat or block fruit.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0038] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, which can be said to be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances. The technical solution of the invention is further explained below in conjunction with the drawings and embodiments.

[0039] refer to Figure 1-Figure 4, a material dropping device according to an embodiment of the present invention comprises a material bladder 6 including a material cavity 612, a material shifting plate 206, and a screw conveying device 80; a partition plate 261 divides the material cavity 612 into a material holding cavity 60 and a material distribution cavity 40, and a material transfer gap D is set between the material holding cavity 60 and the material distribution cavity 40; the screw conveying device 80 is installed in the material distribution cavity 40 (the screw conveying device 80 is installed at the bottom of the material distribution cavity 40, wherein the shape of the bottom of the material distribution cavity 40 is adapted to the outer contour of the screw conveying device 80, and forms a clearance fit), the material shifting plate 206 is rotatably installed in the material transfer gap D (filling the material transfer gap D), and the material shifting plate 206 separates the material holding cavity 60 and the material distribution cavity 40 (reference Figure 3 ); the material transfer plate 206 rotates to flip the material in the material holding chamber 60 and falls into the spiral conveying device 80 in the material distribution chamber 40, and the material is sent out by the spiral conveying device 80.

[0040] The screw conveying device 80 (commonly known as an auger) can be an auger without a center rod or an auger with a center rod. The present invention uses an auger with a center rod as a specific embodiment. The principle that the auger can separate materials by rotating is a prior art and will not be repeated here. A specific embodiment of the rotation of the auger can be driven by a motor (the specific motor can be installed on the outer wall of the material gallbladder, and the rotating shaft 802 driven by the motor extends into the material distribution chamber 40 for connection with the center of the screw conveying device 80). In addition, a specific embodiment of the material transfer plate 206 mentioned in the present technology includes a central rotating shaft 246 and two or more blades 266 evenly distributed on the central rotating shaft 246, refer to Figure 5 (In the figure, five blades 266 are arranged evenly on a central rotating shaft 246, and the material can fall into the gap between two adjacent blades 266, and then be turned over and enter the material distribution chamber when the material plate 206 rotates);

[0041] refer to Figure 2 , Figure 3In one embodiment of the material holding chamber 60 and the material distribution chamber 40, the bottom of the material holding chamber 60 is an inclined structure, that is, an inclined plate 603, the bottom end of the inclined plate 603 borders the material distribution chamber 40, and the partition plate 261 is arranged just above the border of the material holding chamber 60 and the material distribution chamber 40, and the partition plate 261 extends downward, and its end forms a material transfer gap D at the border of the material holding chamber 60 and the material distribution chamber 40, and the material transfer plate 206 is installed in the material transfer gap formed at the border of the material holding chamber 60 and the material distribution chamber 40. The gap D (it is best when the central rotation axis 245 of the material-dividing plate 206 is located directly below the partition 261) is finally achieved to separate the material-containing chamber 60 and the material-dividing chamber 40, while the rotation of the material-dividing plate 206 can flip the meat and vegetables in the material-containing chamber 60 and transfer them into the material-dividing chamber 40; in view of the need for the material-dividing plate 206 to rotate, an arc plate 67 adapted to the rotation radius of the outer contour of the material-dividing plate 206 is also provided at the junction of the material-containing chamber 60 and the material-dividing chamber 40 to accommodate the material-dividing plate 206.

[0042] In view of the above design, the working principle of the present technical solution is that the material (meat chunks, beef brisket) is placed in the material holding chamber 60. Since the material shifting plate 206 is located at the material passing gap D, when the material shifting plate 206 is stationary and not rotating, the material shifting plate 206 can block the material in the material holding chamber 60 to prevent the material from entering the material distribution chamber 40. When the material needs to be delivered, the material shifting plate 206 is driven to rotate, and the material shifting plate 206 shifts the material in the material holding chamber 60 into the material distribution chamber 40. The material entering the material distribution chamber 40 falls onto the screw conveying device 80 and is finally transported out of the material distribution chamber via the screw conveying device 80.

[0043] The material shifting plate 206 is located between the material holding chamber 60 and the material dispensing chamber 40. The rotating shaft of the material shifting plate 206 drives the material shifting plate 206 to flip over and shift the material in the material holding chamber 60 into the material dispensing chamber 40, and then the spiral conveying device 80 performs secondary material dispensing to further disperse the material and transmits the dispersed material out piece by piece. The material shifting plate 206 of the present technical solution can shift a small amount of irregular and mutually adhered materials (meat chunks, etc.) in the material holding chamber 60 into the material dispensing chamber 40, and finally the spiral conveying device 80 performs secondary separation and discharges the materials, that is, it can automatically separate a pile of disordered and mutually adhered materials (meat chunks, etc.) into an appropriate amount of materials (meat chunks, etc.), so as to better achieve the purpose of automatic quantitative material taking, meet the requirements of adding auxiliary materials and vegetables in the field of automatic catering vending and automatic cooking, and ultimately promote the development of the field of automatic catering vending and automatic cooking.

[0044] In view of the fact that the utensils used in the catering industry need to be cleaned and the characteristics of paying attention to hygiene; the present invention is specially designed as follows:

[0045] The material shifting assembly 20 is also comprised of a power device 21 and a side plate 262 for driving the material shifting plate 206 to rotate; the partition plate 261, the material shifting plate 206, the side plate 262 and the power device 21 are assembled on a mounting frame to form a material shifting assembly 20 (refer to Figure 6 ), the material shifting assembly 20 can be detachably installed in the material cavity 612; when the material shifting assembly 20 is installed in the material cavity 612, the partition plate 261, the side plate 262 and the inner wall of the material cavity 612 are combined to form a material holding cavity 60.

[0046] refer to Figure 2 , Figure 3 and Figure 4 The material shifting assembly 20 is installed before the material chamber 612. The material chamber 612 is an integral volume including the material holding chamber 60 and the material distributing chamber 40. When cleaning, the material shifting assembly 20 is disassembled, and the material holding chamber 60 and the material distributing chamber 40 are combined into an integral volume (material chamber 612), which is easier to clean, and the obstructions are greatly reduced. There is no dead angle for cleaning, which is convenient for operators to operate.

[0047] When in use, the material-digging component 20 is vertically inserted into the material cavity 612. The outer wall of the material-digging component 20 can be provided with a positioning component, or the top of the outer wall can be folded and matched with the outer wall of the material bladder 6, so that the material-digging component 20 is fixed at a specific position of the material cavity 612. That is, after the material-digging component 20 is fixed at a specific position of the material cavity 612, the partition plate 261, the side plate 262 and part of the inner wall of the material cavity 612 are combined to form the material cavity 60. The material cavity 612 is surrounded by the material cavity 60. The space outside the material chamber 40 is used as a material distribution chamber 40 and a power chamber 771 for accommodating the power device 21 (the power chamber 771 can be formed by the outer wall of the side plate 262 that is bent at the end and abuts against the inner arm of the material chamber 612 and part of the inner wall of the material chamber 612); finally, the approximate relationship between the material chamber 612, the power chamber 771, the material holding chamber 60 and the material distribution chamber 40 is: the volume of the material chamber 612 is equal to the sum of the power chamber 771, the material holding chamber 60 and the material distribution chamber 40. The reason for enclosing a power chamber 771 here is to separate the material and the power device 21 (after the material transfer assembly 20 is vertically loaded into the material chamber, the power device 21 is just accommodated in the power chamber 771) to prevent them from contacting each other.

[0048] refer to Figure 4 , Figure 8 and Fig. 9The distributing cavity 40 extends out of the outer wall C of the material gallbladder 6, and an opening 401 is arranged at the end of the distributing cavity 40 of the extending part (the length of the distributing cavity of the extending part is shown as M in the figure), and a discharge port 402 facing downward is arranged on the bottom wall of the distributing cavity 40 of the extending part (the length of the distributing cavity of the extending part is shown as M in the figure), and the screw conveying device 80 is detachably installed in the distributing cavity 40 through the opening 401; the screw conveying device 80 conveys the material, and the material falls when it is conveyed to the discharge port 402, that is, the material is transferred by the material transfer plate 206 to the part of the distributing cavity corresponding to the material holding cavity, and then conveyed out by the screw conveying device 80, and falls after passing through the discharge port 402.

[0049] It should be noted that the above emphasis on "the screw conveying device 80 can be detachably installed in the material distribution chamber 40 through the opening 401" means that the screw conveying device 80 can be extended into the material distribution chamber 40 through the opening 401 and installed in the material distribution chamber 40, and can also be pulled out of the material distribution chamber 40 through the opening 401, thereby achieving the purpose of convenient disassembly and assembly.

[0050] More specifically, the present invention provides a specific embodiment of the disassembly of the screw conveying device 80, referring to Figure 4 , Figure 8 and Fig. 9 A fixing plate 803 is provided at one end of the screw conveying device 80, and a matching hole 8011 is provided at the other end of the screw conveying device 80 (provided on the central axis of the screw conveying device. In the case of using a rodless screw conveying device, a small section of the central axis can be additionally provided at both ends to complete the design of the fixing plate 803 and the matching hole 8011); a rotating shaft 802 matching with the matching hole 8011 is provided at the other end of the material distribution chamber 40 opposite to the opening 401, and the rotating shaft 802 is driven by a motor (not shown in the figure) installed on the material gallbladder.

[0051] When the screw conveying device 80 is installed, the screw conveying device 80 extends into the material distribution cavity 40 through the opening 401 at the end of the material distribution cavity 40 (such as Fig. 9 t direction in the figure), finally the rotating shaft 802 is inserted into the matching hole 8011 (so that the rotation of the rotating shaft 802 can drive the installation screw conveying device 80 to rotate), at this time, the fixing plate 803 is against the end of the opening 401 of the material distribution chamber 40, and finally, the fixing plate 803 is fixed to the end of the material distribution chamber 40 with a screw 804. When it is necessary to disassemble, the screw 804 is screwed out, and then the fixing plate 803 can be grasped by hand to pull the screw conveying device 80 out of the material distribution chamber.

[0052] The screw conveying device 80 of the present invention adopts an auger with a center rod, a fixing plate 803 is vertically fixed to one end of the center rod, and a matching hole 8011 is provided at the end of the other end of the center rod.

[0053] It can be seen that the blanking device of the present invention can be disassembled into three parts, namely the spiral conveying device 80, the material dispensing assembly 20 and the material bladder 6. The integrated structure of each module is reasonable, which is convenient for disassembly and installation, and finally easy to clean, keep clean and hygienic, and prevent bacterial growth.

[0054] The power device 21 mentioned above may be a motor, or may be implemented in the following specific manner:

[0055] refer to Figure 6 and Figure 7 The power device 21 includes a rack 202, a cylinder 201 installed on the material-moving assembly 20 and used to drive the rack 202 to move, a gear 205 meshing with the rack 202, and a one-way bearing 207; the one-way bearing 207 is installed on the rotating shaft 802 (the inner ring of the one-way bearing 207 is coaxially sleeved and fixed to the rotating shaft 802), and the gear 205 is installed on the one-way bearing 207 (the gear 205 is coaxially sleeved and fixed to the outer ring of the one-way bearing 802).

[0056] The telescopic rod of the cylinder 201 drives the vertical movement of the rack 202, so that the rack 202 drives the gear 205 to rotate in the forward direction. At this time, the rotating shaft 802 drives the material-pickup plate 206 to rotate from the material-containing chamber 60 to the material-distributing chamber 40, so as to transfer the material in the material-containing chamber 60 into the material-distributing chamber 40; the rack 202 drives the gear 205 to rotate in the reverse direction, and the gear 205 rotates alone. At this time, the gear 205 rotates with the outer ring of the one-way bearing 207, and the rotating shaft 802 does not rotate with it, so the material-pickup plate 206 is stationary.

[0057] One-way bearing 207 is a kind of bearing that can rotate freely in one direction and is locked in the other direction. Figure 6 , the positive rotation of the rack 202 (the rack 202 moves downward) drives the gear 205 to rotate in the locking direction, as shown in the figure M, that is, the outer ring of the one-way bearing 207 cannot rotate relative to its inner ring, that is, the gear 205 drives the inner ring and the outer ring of the one-way bearing 207 to rotate simultaneously in this rotation direction, and the outer ring of the one-way bearing 207 cannot rotate freely relative to its inner ring. Since the inner ring is fixedly installed on the rotating shaft 802 of the material stripping plate 206, and the rotating shaft 802 is affected by an inner ring of the one-way bearing 207, the outer ring of the one-way bearing 207 cannot rotate freely relative to the inner ring. When the rotational force of the circle is exerted, the rotating shaft 802 can rotate on the rotating shaft seat (the rotating shaft 802 can be rotatably installed on the material tapping assembly 20), thereby driving the material tapping plate 206 to rotate; at this time, it can be understood that the one-way bearing 207 rotates with the gear 105 and the one-way bearing 207 and the rotating shaft 802 rotate together, that is, the gear 205 drives the rotation of the one-way bearing 207 to drive the rotating shaft 802 to rotate, thereby driving the material tapping plate 206 matched with the rotating shaft 802 to rotate, so that the material tapping plate 206 can tap the material in the material holding chamber into the material dispensing chamber.

[0058] When in use, it can be set that the stroke of the rack 202 corresponds to a specific rotation angle of the gear 205, and the specific rotation angle corresponds to the rotation angle of the material shifting plate 206, that is, the amount of vegetables and meat that can be shifted from the material holding cavity into the material distribution cavity when the material shifting plate 206 is turned once. Figure 6 In the M direction, for example, refer to Figure 5 If the material dispensing plate 206 is specifically designed to have five blades 266 evenly distributed on a central rotating shaft 246, it can be designed that one stroke of the rack 202 corresponds to a blade flipping angle of 360° / 5=72° (the flipping angle just pushes the material between adjacent blades 266 into the material dispensing chamber).

[0059] On the contrary, the reverse rotation of the rack 202 driving the gear 205 is that the one-way bearing 207 is freely rotating in one direction, in which direction, the one-way bearing 207 can rotate freely on the rotating shaft 802, that is, the rack 202 moves in the reverse direction (the rack 202 moves upward), and the rotation direction of the gear 205 is shown as N in the figure (the reverse movement of the rack 202 can be understood as the movement of the rack 202 returning to its initial position of the forward movement). The reverse movement drives the gear 205 to rotate, and the gear 205 drives the one-way bearing 207 to rotate freely. That is, in this process, the one-way bearing 207 rotates freely relative to the rotating shaft 802, and the rotation of the one-way bearing 207 cannot drive the rotating shaft 802 to rotate at the same time (the outer ring of the one-way bearing 207 rotates with the gear 202, and the inner ring is fixed to the rotating shaft 802, that is, the outer ring rotates, and the inner ring does not rotate), that is, the rotating shaft 802 cannot drive the material plate 206 to rotate, and the material plate 206 does not push the material into the material distribution chamber.

[0060] In summary, reference Figure 6, the rack 202 drives the gear 205 to rotate in the forward direction, that is, the cylinder 201 drives the rack 202 to move downward, and the gear 205 meshing with the rack 202 rotates in the M direction, driving the inner and outer rings of the one-way bearing 207 (because the one-way bearing is locked in this direction, its outer ring cannot rotate relative to the inner ring) to rotate in the M direction at the same time, and because the rotating shaft 802 rotatably installed on the material-dispensing assembly 20 is fixedly installed on the inner ring of the one-way bearing 207, as shown, the rotating shaft 802 also rotates in the M direction, thereby driving the material-dispensing plate 206 to rotate. The angle of rotation of the material-dispensing plate 206 driven by a downward movement of the rack 202 can correspond to the amount of a portion of material (vegetables and meat) dialed from the material holding chamber into the material dispensing chamber. When the rack 202 moves downward for a stroke, the rack 202 is located at the bottom, the cylinder 201 drives the rack 202 in the reverse direction, the rack 202 moves upward, and the gear 205 rotates in the N direction, that is, the gear 205 drives the outer ring of the one-way bearing 207 to rotate in the N direction (the one-way bearing 207 is in a non-locked working state, the outer ring of the one-way bearing 207 rotates with the gear 202, and the inner ring is fixed to the rotating shaft 802, that is, the outer ring rotates, and the inner ring does not rotate), that is, the rack 202 drives the gear 205 to rotate in the reverse direction, the gear 205 rotates alone, and the material stripping plate 206 does not rotate with it. This process is the process of the rack 202 returning to its original position, waiting for the material stripping of the next stroke.

[0061] The above design, on the one hand, can ensure the continuous unidirectional rotation of the material plate from the material holding chamber to the material distribution chamber (as long as the control rack works fast enough), and on the other hand, it can be designed to be an intermittent rotation of the material plate. Each time the material plate rotates, a specific amount of material is conveyed into the material distribution chamber. The specific amount can be determined by the diameter of the material plate and the size of the space formed by each plate.

[0062] refer to Figure 2 , Figure 3 and Figure 7 , and may also include an adjustment plate 203, which is mounted on the partition 261; the adjustment plate 203 is height-adjustable to adjust the size of the material gap D. Specifically, the partition 261 is provided with a threaded hole, and the adjustment plate 203 is provided with a through slot of a certain length, and the height of the adjustment is determined by the length of the through slot. The adjustment screw 204 cooperates with the threaded hole. When the adjustment plate 203 is installed, the adjustment screw passes through the through slot, and the back of the nut of the adjustment screw presses the adjustment plate 203. As the adjustment screw is screwed into the threaded hole, the adjustment plate 203 is fixedly installed on the partition 261. When the material gap D needs to be adjusted, the adjustment screw is loosened. Since the through slot has a gap for the adjustment plate 203 to move up and down relative to the adjustment screw 203, the adjustment plate 203 is moved up and down, so that the height of the adjustment plate 203 extending out of the partition 261 changes. After the required material gap D is finally obtained, the adjustment screw is tightened.

[0063] In view of the randomness of the size or shape of the meat chunks and the randomness of their positions when they are pushed in and turned over by the material pusher plate 206, the material passing gap D can be adjusted according to the size of the meat chunks when using the material dropping device of the present invention. On the one hand, leaving an appropriate gap can allow the meat chunks to be pushed up and located at a high position and to enter the distributing chamber smoothly from the material holding chamber. On the other hand, the excess meat chunks pushed in by the material pusher plate 206 can be blocked and returned to the material holding chamber to facilitate quantitative material removal.

[0064] Preferably, refer to Figure 7 The end of the adjusting plate 203 (the bottom end that participates in forming the material passing gap D) is bent toward the material holding chamber. When the material plate 206 pushes the excessively high material from the material holding chamber (the material is higher than the outer contour of the material plate 206 due to stacking), when the material plate 206 flips over from the material holding chamber to the material distribution chamber with the material, the excessively high material on the material plate 206 hits the curved part at the end of the adjusting plate 203 and is shoveled down and falls back into the material holding chamber, so as to prevent the excessively high material and the end of the partition 261 from being squeezed and sheared.

[0065] refer to Figure 3 More preferably, it further includes a heat-insulating layer 604 and a heating chamber 601 ; the heating chamber 601 is in close contact with the outer wall of the material bladder 6 , and the heat-insulating layer 604 is in close contact with the outer wall of the heating chamber 601 .

[0066] Heating elements such as electric heating wires (such as steam heating) can be set in the heating chamber 601. When in use, appropriate water is added to the heating chamber 601 and heated by heating elements such as electric heating wires 605. The heated water can be kept warm by the insulation layer to reduce heat diffusion. In this way, the materials (meat and vegetables) in the material chamber in the material tank can be kept warm. More preferably, a liquid level sensor and a temperature sensor can be set in the heating chamber 601 respectively to detect the water added to the heating chamber. When the water is less than a preset amount, the valve can be automatically controlled to open, so that water flows from the pipeline into the heating chamber 601 to replenish water until the appropriate amount of water is reached. The temperature sensor is used to detect the temperature in the heating chamber 601. When the temperature drops to a certain value, the heating element such as the electric heating wire is driven to automatically heat to a preset temperature, and finally keep the temperature constant.

[0067] refer to Figure 4 , Figure 8 as well as Fig. 9 Preferably, the distributing chamber 40 is provided with a sieve hole 16 and a conduit 161 connected to the sieve hole 16; the sieve hole 16 is located at the bottom of the distributing chamber 40 (as shown in M ​​in the figure) of the extended part. The conduit 161 is fixed to the outer wall of the distributing chamber 40 and surrounds the sieve hole to drain the juice flowing out of the sieve hole 16.

[0068] Meat and vegetable materials often contain liquids such as soup. When the meat and vegetables are conveyed by the spiral conveying device 80, the meat and vegetables first pass through the sieve holes 16, so that the soup leaks through the sieve holes and enters the conduit for discharge. Then the meat and vegetables continue to be conveyed, and finally are conveyed to the discharge port 402 and discharged through the discharge port 402. In addition, when the material dropping device of the present invention is cleaned, the water flushed from the material chamber can flow through the sieve holes.

[0069] Preferably, refer to Figure 1 , Figure 3 and Figure 4 , also includes a base 90, a spring 30 and a vibrator 70; the vibrator 70 is installed on the material bladder 6, one end of the spring 30 is connected to the base 90, and the other end of the spring 30 is connected to the material bladder 6; the bottom of the material holding cavity 60 is an inclined plate 603, and the bottom end of the inclined plate 603 borders the material distribution cavity 40.

[0070] The vibrator 70 vibrates, thereby driving the material chamber 6 (including other components installed on the material chamber 6, for example, the screw conveying device 80 installed on the material chamber 6 and the material shifting assembly 20, etc.) to vibrate, so that the material in the material holding chamber 60 slides down along the inclined plate 603 toward the bottom, and thus clings to the material shifting plate 206 to wait for the rotation of the material shifting plate 206. Finally, the rotation of the material shifting plate 206 will flip the material clinging to the material shifting plate 206 itself and shift it into the material distribution chamber 40. Such a cyclic vibration can ensure that the material in the material holding chamber 60 keeps sliding down and clinging to the material shifting plate 206, and the material shifting plate 206 can Block the material in the material holding chamber 60 to prevent the material from falling directly into the material distribution chamber 40. The final effect is that the material plate 206 can be rotated as needed to transfer the material in the material holding chamber 60 into the material distribution chamber 40, waiting for the spiral conveying device 80 to separate and transport the material again. Finally, the material can be sent out in a single block to facilitate subsequent measurement. In addition, when the material dropping device is installed on an auxiliary machine (or other table) for use, the base is fixed on the machine. Since the base and the material bladder are separated by a spring, the base can reduce the impact of the vibration of the vibrator and the vibration of the entire machine.

[0071] refer to Figure 1The technology of the present invention also includes a weight metering module 716, which is arranged below the discharge port 402. The material-dividing plate 206 dices an appropriate amount of meat chunks from the whole pile of meat chunks stored in the material-containing cavity 60. This process is equivalent to the first separation and removal of the meat chunks. The separated meat chunks fall onto the spiral conveying device 80 of the material-dividing cavity 40 as the material-dividing plate 206 turns over, and then undergo a second separation by the spiral conveying device 80, thereby further dispersing the meat chunks and conveying them to the discharge port 402. The effect of this process is that Take the meat from the pile of meat pieces, and disperse the taken meat, and finally achieve the purpose of a single piece of meat falling from the material port 402. The single pieces of meat that fall in sequence fall into the weight metering module 716, and the weight gradually accumulates and is recognized by the weight metering module 716. After finally reaching the required weight, the weight metering module 716 can send a signal to drive the cylinder 201 to drive the motor of the screw conveying device to stop working, so that the material transfer plate 206 stops transferring the meat pieces into the material distribution chamber, and then the meat pieces of a specific weight obtained in the weight metering module 716 can be taken out. In this way, the purpose of quantitative material removal can be achieved. The above weight metering module 716 can also be replaced by a photoelectric sensor, which is installed on the trajectory of the meat pieces falling. When the meat pieces are detected to fall, they are counted. In this way, the total count value is accumulated until the predetermined number is met, and the material dropping can be controlled to be suspended.

[0072] Specifically, the weight metering module 716 of the present invention includes a material bowl 74, a flip cylinder 75, a weight detector (which can be a gravity sensor) and a rocker arm; the rocker arm is mounted on the flip cylinder 75, the gravity sensor is mounted on the rocker arm, and the material bowl 74 is mounted on the gravity sensor; a single piece of meat falls into the material bowl 74 and is monitored and measured in real time by the gravity sensor, and the single piece of meat continues to fall, and the accumulated weight, until it reaches a predetermined weight, sends a signal to control the material plate 206 and the screw conveyor 80 to stop working, and at the same time the flip cylinder 75 drives the rocker arm to flip 180°, so that the meat of a specific weight in the material bowl 74 falls into the meat bowl 76, completing the work of taking a quantitative piece of meat. The above cycle work can take meat in a cyclical and quantitative manner.

[0073] The invention can be used for block meat or block fruit analogs, such as cooked meat, vegetables, dried fruits, grains, rice, meatballs, candies, shellfish, granular seasonings, etc.
