Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a feeding mechanism for a donut frying machine and a frying machine using the feeding mechanism. Background Technology

[0002] Donut frying machines are mainly used for frying donuts. They replace manual frying with machine frying, increasing the yield of fried foods. In existing technology, traditional donut frying machines mainly consist of an oil tank, a frying frame, and a heater. For example, Chinese patent CN213695486U discloses a novel donut frying machine, including a frying mechanism, a feeding mechanism, and an electrical box. The frying mechanism includes: a base with a frying groove; a first rotating rod and a second rotating rod, rotatably positioned at the bottom of the center of the frying groove; a first synchronous belt surrounding the first and second rotating rods; a third rotating rod rotating at the bottom of one end of the frying groove; a fourth rotating rod rotating at the top of one end of the frying groove; and a second synchronous belt surrounding the third and fourth rotating rods. The first synchronous belt has multiple first flow holes spaced apart, and the second synchronous belt has multiple second flow holes spaced apart. Through the above method, the synchronous belt of the new donut fryer used to convey donuts is equipped with flow holes, which makes it less likely for the output donuts to carry oil residue and impurities, and also makes the output donuts carry less oil. However, the above-mentioned donut fryer and the existing donut fryers generally have the following defects: (1) The feeding mechanism is complicated and the feeding efficiency is slow. The center hole of the blank is easily blocked during feeding, which causes the center hole to be blocked after frying, resulting in unqualified donuts; (2) The degree of automation is low and the frying efficiency is low. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model proposes a feeding mechanism for a donut fryer, which features a simple structure, high feeding efficiency, and solves the problem of easy clogging of the center hole of the dough during feeding. This utility model also provides a donut fryer using this feeding mechanism.

[0004] To achieve the above technical solution, this utility model provides a feeding mechanism for a donut frying machine, comprising: a support rod; a mounting plate fixed to the top of the support rod via a mounting plate fixing bushing; a feeding motor mounted on the mounting plate; a turntable mounted on the output shaft of the feeding motor; a protrusion mounted on the end edge of the front side of the turntable; and a discharge pull rod limiting block mounted on the mounting plate below the turntable, the discharge pull rod limiting block having a limiting groove; and the discharge pull rod penetrating from top to bottom. The limiting block has a limiting groove, and the protrusion on the turntable is connected to the top of the discharge rod by a connecting rod. A conical discharge barrel is installed at the bottom of the mounting plate. The discharge rod extends downward to the discharge pipe at the bottom of the conical discharge barrel. A piston sealing ring that matches the discharge pipe at the bottom of the conical discharge barrel is installed at the bottom of the discharge rod. A hollow hole plug is provided in the center of the piston sealing ring. A forming blade is installed on the discharge rod above the piston sealing ring, and a pressure cap is installed on the discharge rod above the forming blade.

[0005] In the above technical solution, during actual operation, the dough is simply placed inside the conical discharge hopper. When the discharge rod pushes the piston sealing ring to the discharge pipe at the bottom of the conical discharge hopper, the conical discharge hopper is in a closed state. When the feeding motor drives the turntable to rotate, the turntable, through the connecting rod installed on the protrusion, drives the discharge rod to move up and down periodically along the limiting groove set on the discharge rod limiting block under the restriction of the discharge rod limiting block. When the discharge rod drives the piston sealing ring to move upward to above the discharge pipe, the dough falls into the discharge pipe under the action of gravity. Then, the discharge rod drives the piston sealing ring to move downward. Through the forming blade installed on the discharge rod, the piston sealing ring, and the hollow hole plug installed in the center of the piston sealing ring, it is ensured that the pressed blank can maintain a central hole during the forming process, preventing the central hole of the blank from being blocked during feeding, thereby improving the quality of the blank during forming. Because the discharge rod moves up and down periodically under the drive of the feeding motor, it can continuously drive the piston seal ring to move up and down periodically inside the discharge pipe, continuously pressing the billet up and down, thereby improving the feeding efficiency and stability of the billet.

[0006] Preferably, the conical discharge hopper is fixed to the bottom of the mounting plate by multiple end locking plates to ensure that the conical discharge hopper can be stably fixed to the bottom of the mounting plate.

[0007] This utility model also provides a donut frying machine, including the above-mentioned feeding mechanism and frying mechanism. In actual operation, the feeding mechanism presses the dough into the frying mechanism, and the frying mechanism frys the dough to form donuts.

[0008] Preferably, the frying mechanism includes a frying tank, with a support rod connecting sleeve provided on the end edge of the frying tank. The support rod of the feeding mechanism is fixed inside the support rod connecting sleeve. An oil stirring impeller is installed inside the frying tank. The drive shaft of the oil stirring impeller is connected to a stirring motor installed outside the frying tank. A tilting drive motor is installed on the front side of the stirring motor. A swing plate is installed on the output shaft of the tilting drive motor. The swing plate is connected to the top of a tilting lever via a connecting rod. The bottom of the tilting lever is connected to one end of a deflecting plate. The other end of the deflecting plate is connected to the rear end of a first pull rod. The front end of the first pull rod is connected to the rear end of a first tilting plate shaft and a second pull rod, respectively. A first tilting plate is installed on the first tilting plate shaft. A second tilting plate shaft is installed on the front end of the second pull rod. A second tilting plate is installed on the second tilting plate shaft. In the above technical solution, during actual operation, the frying tank is filled with hot oil at high temperature. The oil is slowly pushed forward by the tumbling of the oil agitator impeller, which in turn moves the dough forward. When the fried dough moves to the first flipping plate, the flipping drive motor drives the first flipping plate to rotate 90° through the transmission of the plate, flipping lever, deflector plate, first pull rod, and first flipping plate shaft. This flips the dough at the first flipping plate to the rear of the first flipping plate for frying on the other side, and pushes the fried donuts to continue moving forward to the second flipping plate. Similarly, through the transmission of the plate, flipping lever, deflector plate, first pull rod, second pull rod, and second flipping plate shaft, the second flipping plate rotates, flipping the fried donuts out of the frying tank to the external collection tank for collection.

[0009] Preferably, both the first and second flip plates are provided with perforated oil leakage holes to prevent hot oil from splashing during the flipping process.

[0010] Preferably, the frying tank is equipped with an oil inlet pipe and an oil outlet pipe to facilitate the entry and exit of hot oil.

[0011] Preferably, a heater is installed inside the frying tank, and a control box is installed outside the frying tank. The control box is electrically connected to the feeding motor, the stirring motor, the tilting drive motor, and the heater. In actual operation, various operating parameters of the equipment can be set through the control box.

[0012] The beneficial effects of the feeding mechanism of the donut fryer provided by the utility model are as follows:

[0013] (1) The feeding mechanism of this donut frying machine has a simple structure, is easy to operate, and has high feeding efficiency, solving the problem of easy blockage of the center hole of the dough during feeding. In actual operation, the dough is simply placed in the conical discharge hopper. When the discharge rod pushes the piston sealing ring to the discharge pipe at the bottom of the conical discharge hopper, the conical discharge hopper is in a closed state. When the feeding motor drives the turntable to rotate, the turntable rotates and, through the connecting rod installed on the protrusion, drives the discharge rod to move up and down periodically along the limiting groove set on the discharge rod limiting block under the limiting action of the discharge rod limiting block. When the discharge rod drives the piston sealing ring to move upward to the top of the discharge pipe, the dough falls into the discharge pipe under the action of gravity. Then the discharge rod drives the piston sealing ring to move downward. Through the forming blade installed on the discharge rod, the piston sealing ring, and the hollow hole plug installed in the center of the piston sealing ring, it is ensured that the pressed dough can maintain a center hole during the forming process, preventing the center hole of the dough from being blocked during feeding, thereby improving the quality of the dough during forming. Because the discharge rod moves up and down periodically under the drive of the feeding motor, it can continuously drive the piston seal ring to move up and down periodically inside the discharge pipe, continuously pressing the billet up and down, thereby improving the feeding efficiency and stability of the billet.

[0014] (2) This donut frying machine has a high degree of automation, realizing automatic feeding, double-sided frying and automatic discharging in the donut making process, with high working efficiency and stable frying quality. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: A feeding mechanism for a donut frying machine.

[0026] Reference Figures 1 to 5As shown, a feeding mechanism for a donut frying machine includes: a support rod 101, a mounting plate 103 fixed to the top of the support rod 101 by a mounting plate fixing bushing 102, a feeding motor 104 mounted on the mounting plate 103, a turntable 107 mounted on the output shaft of the feeding motor 104, a protrusion 108 mounted on the front side edge of the turntable 107, a discharge pull rod limiting block 110 mounted on the mounting plate 103 below the turntable 107, a limiting groove provided on the discharge pull rod limiting block 110, and a discharge pull rod 106 passing through the limiting groove provided on the discharge pull rod limiting block 110 from top to bottom. The protrusion 108 on the turntable 107 and the top of the discharge pull rod 106 are connected by a connecting rod 109. A conical discharge barrel 111 is installed at the bottom of the mounting plate 103. The conical discharge barrel 111 is fixed to the bottom of the mounting plate 103 by multiple end locking plates 105 to ensure that the conical discharge barrel 111 can be stably fixed at the bottom of the mounting plate 103. The discharge rod 106 extends downward to the discharge pipe 116 at the bottom of the conical discharge barrel 111. A piston sealing ring 115 matching the discharge pipe 116 at the bottom of the conical discharge barrel 111 is installed at the bottom of the discharge rod 106. A hollow hole plug 114 is provided in the center of the piston sealing ring 115. A forming blade 113 is installed on the discharge rod 106 above the piston sealing ring 115. A pressure cap 112 is installed on the discharge rod 106 above the forming blade 113.

[0027] This donut frying machine features a simple feeding mechanism that is easy to operate and highly efficient, solving the problem of easy clogging of the center hole of the dough during feeding. In actual operation, simply place the dough inside the conical discharge hopper 111. When the discharge rod 106 pushes the piston sealing ring 115 to the discharge pipe 116 at the bottom of the conical discharge hopper 111, the conical discharge hopper 111 is closed. When the feeding motor 104 drives the turntable 107 to rotate, the turntable 107, through the connecting rod 109 mounted on the protrusion 108, drives the discharge rod 106 to move up and down periodically along the limiting groove provided on the discharge rod limiting block 110 under the restriction of the discharge rod limiting block 110. When the material pull rod 106 moves the piston sealing ring 115 upward to above the discharge pipe 116, the dough falls into the discharge pipe 116 under gravity. Then, the material pull rod 106 moves the piston sealing ring 115 downward. Through the forming blade 113 installed on the material pull rod 106, the piston sealing ring 115, and the hollow hole plug 114 installed in the center of the piston sealing ring 115, it is ensured that the pressed blank can maintain a central hole during the forming process, preventing the central hole of the blank from being blocked during feeding, thereby improving the quality of the blank during forming. Since the material pull rod 106 moves up and down periodically under the drive of the feeding motor 104, it can continuously drive the piston sealing ring 115 to move up and down periodically in the discharge pipe 116, continuously pressing the blank up and down, thereby improving the feeding efficiency and stability of the blank.

[0028] Example 2: A donut frying machine.

[0029] Reference Figures 1 to 8 As shown, a donut frying machine includes a feeding mechanism 100 and a frying mechanism 200 as described in Example 1. In actual operation, the feeding mechanism 100 presses the dough into the frying mechanism 200, and the frying mechanism 200 frys the dough to form donuts.

[0030] Reference Figure 7 and Figure 8As shown, the frying mechanism 200 includes a frying tank 201. A support rod connecting sleeve 208 is provided on the end edge of the frying tank 201. The support rod 101 of the feeding mechanism 100 is fixed inside the support rod connecting sleeve 208. An oil stirring impeller 207 is installed inside the frying tank 201. The drive shaft of the oil stirring impeller 207 is connected to a stirring motor 206 installed on the outside of the frying tank 201. A tilting drive motor 202 is installed on the front side of the stirring motor 206. A tilting plate is installed on the output shaft of the tilting drive motor 202. The tilting plate passes through... The top of the connecting rod is connected to the flipping lever 203, the bottom of the flipping lever 203 is connected to one end of the deflecting connecting plate 211, and the other end of the deflecting connecting plate 211 is connected to the rear end of the first pull rod 212. The front end of the first pull rod 212 is connected to the rear end of the first flipping plate shaft 213 and the second pull rod 214, respectively. The first flipping plate 204 is mounted on the first flipping plate shaft 213, the front end of the second pull rod 214 is mounted on the second flipping plate shaft 215, and the second flipping plate 205 is mounted on the second flipping plate shaft 215. Both the first flipping plate 204 and the second flipping plate 205 are provided with perforated oil leakage holes to prevent hot oil from splashing during the flipping process. The frying tank 201 is provided with an oil inlet pipe 210 and an oil outlet pipe to facilitate the entry and exit of hot oil. A heater is installed inside the frying tank 201, and a control box 209 is installed outside the frying tank 201. The control box 209 is electrically connected to the feeding motor 104, the stirring motor 206, the tilting drive motor 202 and the heater. In actual operation, various working parameters of the equipment can be set through the control box.

[0031] In this embodiment, during actual operation, the frying tank 201 is filled with high-temperature hot oil. The oil is slowly propelled forward by the tumbling action of the oil agitator impeller 207, which in turn moves the food blank forward. When the fried food blank reaches the first flipping plate 204, the flipping drive motor 202, through the transmission of the swing plate, flipping lever 203, deflector plate 211, first pull rod 212, and first flipping plate shaft 213, causes the first flipping plate 204 to flip 90°. The dough at the first flipping plate 204 is flipped to the back of the first flipping plate 204 for frying on the other side, and the fried donuts are pushed forward to the second flipping plate 205. Similarly, through the transmission of the tray, flipping lever 203, deflecting connecting plate 211, first pull rod 212, second pull rod 214, and second flipping plate shaft 215, the second flipping plate 205 is flipped, and the finished donuts that have been fried on both sides are flipped out of the frying tank 201 and collected in the external collection tank.
