Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a double-row donut frying machine. 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.

[0003] In the existing technology, the traditional donut fryer mainly consists of an oil tank, a donut fryer frame, and a heater, which can replace some manual frying. The existing donut fryers generally have the following defects: (1) They can only perform single-row feeding, with low automation and low frying efficiency; (2) The feeding mechanism is complicated, the feeding efficiency is slow, and the center hole of the dough is easily blocked during feeding, resulting in blockage of the center hole after frying, which leads to unqualified donuts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a double-row donut frying machine. By modifying the structure of the feeding mechanism and the feeding movement drive mechanism, the feeding mechanism can achieve double-row feeding, thereby improving feeding efficiency.

[0005] To achieve the above technical solution, this utility model provides a double-row donut frying machine, comprising: a frying mechanism, the frying mechanism including a frying tank, a support rod fixing plate provided on the rear end side of the frying tank, and a flipping component and an electric heating tube installed inside the frying tank; a feeding mechanism installed on the frying mechanism, the feeding mechanism including a support rod, the bottom of the support rod being fixed to the support rod fixing plate provided on the rear end side of the frying tank by a bearing, an upper mounting frame being installed on the top of the support rod, and a discharge component being installed on the upper mounting frame; and a feeding moving drive mechanism installed on the frying mechanism, the feeding moving drive mechanism including a transmission shaft installed on the frying tank, one end of the transmission shaft being connected to a support rod moving drive motor through a coupling, the other end of the transmission shaft being installed with a turntable, one end of a transmission connecting rod being connected to the end edge of the turntable through a pin, and the other end of the transmission connecting rod being connected to the support rod through a support rod connecting rod.

[0006] In the above technical solution, during actual operation, the feeding and moving drive mechanism drives the transmission shaft to rotate via the support rod moving drive motor. The transmission shaft drives the turntable to rotate. During the rotation of the turntable, the support rod on the feeding mechanism is driven to rotate back and forth periodically on the support rod fixing plate of the frying mechanism through the transmission connecting rod and the support rod connecting rod. This causes the discharge component installed on the top of the support rod to swing back and forth periodically. Combined with the intermittent discharge of the discharge component, the feeding mechanism can move and feed in double rows, continuously dropping the blanks into the frying tank. The flipping component installed in the frying tank can both agitate the oil in the frying tank from back to front and flip the blanks, achieving double-sided frying of the blanks.

[0007] Preferably, the discharge assembly includes a feeding drive motor mounted on the upper mounting frame. A turntable is mounted on the output shaft of the feeding drive motor. A protrusion is mounted on the end edge of the front side of the turntable. A lower mounting frame is provided on the top of the conical discharge barrel. The lower mounting frame and the upper mounting frame are fastened together by bolts. A discharge pull rod limiting block is mounted on the lower mounting frame. A limiting groove is provided on the discharge pull rod limiting block. The discharge pull rod passes through the limiting groove provided on the discharge pull rod limiting block from top to bottom. The protrusion on the turntable is connected to the top of the discharge pull rod by a connecting rod. The discharge pull rod extends downward to the discharge pipe at the bottom of the conical discharge barrel. A piston sealing ring matching the discharge pipe at the bottom of the conical discharge barrel is installed on the bottom of the discharge pull rod. A forming blade is installed on the discharge pull rod above the piston sealing ring. In actual operation, the dough is simply placed inside the conical discharge hopper. When the discharge lever pushes the piston sealing ring to the discharge pipe at the bottom of the conical discharge hopper, the hopper is closed. When the feeding drive motor drives the turntable to rotate, the turntable, via a connecting rod mounted on a protrusion, drives the discharge lever to move up and down periodically along the limiting groove on the discharge lever limiting block, under the constraint of the discharge lever limiting block. When the discharge lever moves the piston sealing ring upwards to above the discharge pipe, the dough falls into the discharge pipe under gravity. Then, the discharge lever moves the piston sealing ring downwards, and through the forming blades and piston sealing ring mounted on the discharge lever, the dough in the discharge pipe is pressed downwards into the frying tank. Because the discharge lever moves up and down periodically under the drive of the feeding drive motor, the piston sealing ring can be continuously driven to move up and down periodically within the discharge pipe, continuously pressing the dough, thereby improving the feeding efficiency and stability of the dough. Furthermore, it can be used in conjunction with a feeding and moving drive mechanism to drive the support rod to rotate, thereby achieving double-row feeding and further improving frying efficiency.

[0008] Preferably, the piston sealing ring is provided with a hollow hole plug at its center to ensure 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 blank forming.

[0009] Preferably, the flipping assembly includes a drive shaft installed laterally within the frying tank, a flipping plate mounted on the drive shaft, and perforations evenly distributed on the surface of the flipping plate. One end of the drive shaft is connected to a flipping drive motor. In actual operation, the flipping drive motor drives the flipping plate to rotate. During rotation, the flipping plate can both push the oil forward and flip the blanks that have moved to the flipping plate, thus achieving frying on the other side.

[0010] Preferably, a heating control box is installed on one side of the frying tank. The heating control box is connected to the electric heating tube installed in the frying tank. In actual operation, the heating parameters of the electric heating tube can be controlled through the heating control box.

[0011] Preferably, a front baffle is installed at the front end of the frying tank, and the fried donuts will be collected at the front baffle for the operator to collect.

[0012] The advantages of the double-row donut fryer provided by this utility model are as follows: This double-row donut fryer has a simple structure and is easy to operate. Through the structural design of the feeding mechanism and the feeding moving drive mechanism, the feeding mechanism can achieve double-row feeding, thereby improving feeding efficiency. In actual operation, the feeding moving drive mechanism drives the transmission shaft to rotate through the support rod moving drive motor. The transmission shaft drives the turntable to rotate. During the rotation of the turntable, the transmission connecting rod and the support rod connecting rod drive the support rod on the feeding mechanism to rotate back and forth periodically on the support rod fixing plate of the frying mechanism. This, in turn, drives the discharge component installed on the top of the support rod to swing back and forth periodically. Combined with the intermittent discharge of the discharge component, the feeding mechanism can achieve double-row feeding, continuously dropping the dough into the frying tank. The flipping component installed in the frying tank can both agitate the oil in the frying tank from back to front and flip the dough, achieving double-sided frying of the dough.

[0019] 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.

[0020] Example: A double-row donut frying machine.

[0021] Reference Figures 1 to 5 As shown, a double-row donut frying machine includes:

[0022] A frying mechanism 200 includes a frying tank 201 with a support rod fixing plate 207 at its rear end. A flipping assembly 202 and an electric heating element 204 are installed inside the frying tank 201. The flipping assembly 202 includes a drive shaft installed laterally within the frying tank 201, a flipping plate mounted on the drive shaft, and perforations evenly distributed on the surface of the flipping plate. One end of the drive shaft is connected to a flipping drive motor. In actual operation, the flipping drive motor drives the flipping plate to rotate. During rotation, the flipping plate can both push the oil forward and flip the material that has moved to the flipping plate, achieving frying on the other side. A heating control box 203 is installed on one side of the frying tank 201, connected to the electric heating element 204 installed inside the frying tank 201. In actual operation, the heating parameters of the electric heating element 204 can be controlled through the heating control box 203. A front baffle 205 is installed at the front end of the frying tank 201, where fried donuts will gather and wait for collection by the operator. An oil outlet pipe is installed at the bottom of the frying tank 201 for easy oil replacement.

[0023] A feeding mechanism 100 is installed on the frying mechanism 200. The feeding mechanism 100 includes a support rod 101. The bottom of the support rod 101 is fixed to a support rod fixing plate 207 provided on the rear end side of the frying tank 201 by a bearing 102. An upper mounting bracket 103 is installed on the top of the support rod 101. A feeding drive motor 104 is installed on the upper mounting bracket 103. A turntable 105 is installed on the output shaft of the feeding drive motor 104. A protrusion 106 is installed on the end edge of the front side of the turntable 105. A lower mounting bracket 113 is provided on the top of the conical discharge hopper 114. The lower mounting bracket 113 and the upper mounting bracket 103 are fastened together by bolts. The lower mounting bracket 113 is equipped with a discharge rod limiting block 112, which has a limiting groove. The discharge rod 108 extends from top to bottom through the limiting groove on the discharge rod limiting block 112. The protrusion 106 on the turntable 105 is connected to the top of the discharge rod 108 via a connecting rod 107. The discharge rod 108 extends downward to the discharge pipe 115 at the bottom of the conical discharge barrel 114. A piston sealing ring 110 matching the discharge pipe 115 at the bottom of the conical discharge barrel 114 is installed at the bottom of the discharge rod 108. A forming blade 109 is installed on the discharge rod 108 above the piston sealing ring 110. A hollow hole plug 111 is provided in the center of the piston sealing ring 110 to ensure 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 blank forming.

[0024] In actual operation, the dough is simply placed inside the conical discharge hopper 114. When the discharge lever 108 pushes the piston sealing ring 110 to the discharge pipe 115 at the bottom of the conical discharge hopper 114, the conical discharge hopper 114 is in a closed state. When the feeding drive motor 104 drives the turntable 105 to rotate, the turntable 105, through the connecting rod 107 mounted on the protrusion 106, drives the discharge lever 108 to move along the discharge lever limit block 112 under the restriction of the discharge lever limit block 112. The limiting groove on the discharge pull rod limiting block 112 moves up and down periodically. When the discharge pull rod 108 drives the piston sealing ring 110 upward to above the discharge pipe 115, the dough falls into the discharge pipe 115 under gravity. Then, the discharge pull rod 108 drives the piston sealing ring 110 downward, and the forming blade 109 and piston sealing ring 110 installed on the discharge pull rod 108 press the dough in the discharge pipe 115 downward into the frying tank 201. Since the discharge pull rod 108 moves up and down periodically under the drive of the feeding drive motor 104, it can continuously drive the piston sealing ring 110 to move up and down periodically in the discharge pipe 115, continuously pressing the dough up and down, thereby improving the feeding efficiency and stability of the dough. Furthermore, it can be used in conjunction with the feeding moving drive mechanism 300 to drive the support rod 101 to rotate, achieving double-row feeding and further improving the frying efficiency.

[0025] A feeding and moving drive mechanism 300 is installed on the frying mechanism 200. The feeding and moving drive mechanism 300 includes a drive shaft 303 installed on the frying tank 201. One end of the drive shaft 303 is connected to the support rod moving drive motor 301 through a coupling 302. A turntable 304 is installed on the other end of the drive shaft 303. One end of the transmission connecting rod 305 is connected to the end edge of the turntable 304 through a pin. The other end of the transmission connecting rod 305 is connected to the support rod 101 through a support rod connecting rod 306. In actual operation, the support rod moving drive motor 301 drives the transmission shaft 303 to rotate, and the transmission shaft 303 drives the turntable 304 to rotate. During the rotation, the turntable 304 drives the support rod 101 on the feeding mechanism 100 to rotate back and forth periodically on the support rod fixing plate 207 of the frying mechanism 200 through the transmission connecting rod 305 and the support rod connecting rod 306. This causes the discharge component installed on the top of the support rod 101 to swing back and forth periodically. Combined with the intermittent discharge of the discharge component, the feeding mechanism 100 can move and double-row feed, continuously dropping the blanks into the frying tank 201. The flipping component 202 installed in the frying tank 201 can both move the oil in the frying tank 201 from back to front and flip the blanks, realizing double-sided frying of the blanks.

[0026] This double-row donut frying machine has a simple structure and is easy to operate. By setting the structure of the feeding mechanism 100 and the feeding moving drive mechanism 300, the feeding mechanism 100 can move to feed in a double row, thereby improving the feeding efficiency.

[0027] The above description is only a preferred embodiment of the present utility model. However, the present utility model should not be limited to the content disclosed in the embodiment and the accompanying drawings. Therefore, any equivalent or modified embodiments made without departing from the spirit disclosed in the present utility model shall fall within the protection scope of the present utility model.
