Description

Technical Field

[0001] The utility model relates to the technical field of choppers, in particular to a food chopper. Background Art

[0002] In the process of making pre-prepared dishes, a variety of foods need to be used to match to ensure the nutritional balance of the dishes. Different foods contain different nutrients, such as protein, fat, carbohydrates, vitamins and minerals. By matching a variety of foods together, the nutritional components of pre-prepared dishes can be made more comprehensive and meet the human body's needs for multiple nutrients. When processing fruits and vegetables and other foods, these foods need to be diced or shredded, collectively referred to as shredding. There are several reasons why these foods need to be shredded. First, it is easy to cook. Chopping foods can make them easier to cook thoroughly. For some foods that are hard or difficult to cook, dicing or shredding them can reduce their volume and increase the heating area, thereby speeding up the cooking speed. Second, it is easy to taste. Chopping foods can make it easier for seasonings to penetrate into the food, making the food more flavorful. This is especially important for some pre-prepared dishes that need to be marinated or stewed. Third, it is easy to eat. Chopping foods can make it easier for consumers to chew and swallow. This is especially important for people with bad teeth or weak digestive function. At the same time, diced or shredded food is easier to eat with other ingredients, increasing the diversity of the dish.

[0003] The current shredding devices mainly have the following problems: first, the internal structure is too complicated, and it is difficult to clean the interior after each use; second, the current shredding devices are difficult to switch functions. When switching between the dicing and shredding functions, many components need to be dismantled and installed. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a food chopper that can quickly chop food, quickly switch functions, and is easy to clean after use, so as to solve the problems described in the background technology.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A food chopper comprises a support frame arranged on a base, a connecting rod is arranged horizontally at a fixed height in the middle of the support frame, a cylinder with upper and lower openings is fixedly arranged at the end of the connecting rod, a cutting frame is detachably installed at the opening at the lower end of the cylinder, a cutting net is fixedly arranged in the cutting frame, the top of the cutting net does not exceed the bottom surface of the cylinder upward, a knife entry groove is also arranged between the cutting net and the inner side wall of the cutting frame, a piston column is slidably inserted in the cylinder at the upper end of the cutting frame, a feeding port is also arranged on the side wall of the cylinder just above the knife entry groove, and a top is fixedly arranged on the top of the support frame A pneumatic push rod is fixedly arranged at the bottom of the top frame, a telescopic rod of the pneumatic push rod extends downward and is connected to the top of the piston column, a cutter matching the cutter groove is arranged at the edge of the bottom surface of the piston column just above the cutter groove, the width of the cutter and the cutter groove is greater than the width of the feed port, when the piston column moves to the lowest position, the bottom of the piston column is flush with the bottom of the cylinder body and the side wall of the piston column completely blocks the feed port, a feeding device is connected to the outside of the feed port, and a cutting device for transversely cutting the extrudate at the bottom of the cylinder body is also arranged outside the cylinder.

[0007] When using the above scheme, fruits and vegetables are put into the feeding device and then enter the feeding port. When the pneumatic push rod pulls the piston column upward, the fruits and vegetables enter the cylinder from the feeding port. When the pneumatic push rod pushes the piston column downward, the cutter at the bottom of the piston column cuts the fruits and vegetables that are extending out of the feeding port. The fruits and vegetables pushed downward by the bottom of the piston column are cut by the cutting net and come out from the bottom of the cutting net to form extrudates. The cutting device then cuts the extrudates horizontally to shred the fruits and vegetables. When the piston column is pressed to the bottom, the fruits and vegetables in the cylinder are basically cut, and at this time the side wall of the piston column blocks the feeding port, and new fruits and vegetables are blocked in the feeding device. When the piston column rises again, the feeding port is exposed, and fruits and vegetables are fed again, and this cycle repeats.

[0008] When the cutting net is a rectangular grid knife, the extrudate is a strip, and after the cutting device cuts horizontally, the strip is cut into granules. When the cutting net is a grid knife, the extrudate is a sheet, and after the cutting device cuts horizontally, the sheet is cut into filaments. By replacing the cutting frame and the cutting net inside it, you can switch between the dicing function and the shredding function. And because the cutting frame is exposed at the bottom of the cylinder, it is more convenient to disassemble the cutting frame.

[0009] When the shredding operation is completed, the cutting frame can be disassembled to rinse the inner wall of the cylinder and the cutting net, which is convenient and quick.

[0010] By setting the knife entry groove, the cutter can have space to be inserted, so that the bottom of the piston column and the top of the cutting net can achieve zero distance contact as much as possible.

[0011] A further technical solution is that the cutting device includes a servo motor fixedly mounted on the outer wall of the cylinder, the output shaft of the servo motor extends downward and is provided with a driving gear, the cutting device also includes a sleeve fixedly mounted on the outer wall of the cylinder, a rotating shaft is rotatably passed through the sleeve, a driven gear is provided on the top of the rotating shaft, the driving gear and the driven gear are meshed, a cutter head seat is detachably mounted on the bottom of the rotating shaft, cutting knives are symmetrically arranged horizontally on the cutter head seat, and the cutting knife covers the lower end opening range of the cylinder when the cutter head seat rotates.

[0012] When using the above solution, the servo motor drives the active gear to rotate, the active gear drives the driven gear to rotate, the driven gear drives the shaft to rotate, the shaft drives the cutter head seat to rotate, and the cutter head seat drives the cutting knife installed thereon to rotate. The servo motor can effectively control the cutting speed, and with the downward pressing speed of the pneumatic push rod, it can effectively control the size of the required cutting object.

[0013] A further technical solution is that the feeding device includes a feeding transverse pipe horizontally connected to the feeding port, a feeding inclined pipe obliquely connected to the upper end of the feeding transverse pipe, and a feeding hopper connected to the upper end of the feeding inclined pipe.

[0014] When the above solution is used, the feed hopper provides a wide feeding area for easy feeding, and the cooperation of the feed inclined tube and the feed horizontal tube can make the food always maintain the kinetic energy of sliding downward outside the feed port, which is convenient for automatic feeding.

[0015] A further technical solution is that the inner cross-section of the cylinder is rectangular, and the feed port is completely opened on one inner side wall of the cylinder.

[0016] A further technical solution is that a plurality of threaded holes are opened upward from the bottom of the side wall of the cylinder, a groove is opened upward from the bottom of the cutting frame, the positions of the grooves correspond one to one with the positions of the threaded holes, a through hole is opened upward from the top of the groove, a bolt is slidably passed through the through hole, the cutting frame is screwed into the threaded hole of the cylinder by the bolts, and the bottom of the bolt does not exceed the bottom surface of the cutting frame.

[0017] The grooves, through holes and threaded holes are provided in combination with the screw connection of bolts, which facilitates installation and disassembly on the one hand, and makes the bolt part extend beyond the bottom of the cutting frame on the other hand, so that the cutting knife can be closer to the cutting frame.

[0018] A further technical solution is that the support frame includes two groups of separately arranged vertical rods, the cylinder is arranged between the two groups of vertical rods, each group of vertical rods includes at least two vertical rods, one end of the connecting rod is fixed on the vertical rod, and the other end of the connecting rod is fixed on the outer wall of the cylinder.

[0019] By setting up two sets of vertical rods, the structure is made more stable.

[0020] A further technical solution is that the upper end surface of the piston column is recessed downward to form a hole, so that the piston column forms a rectangular barrel structure with an open upper end, the pneumatic push rod is partially arranged within the hole, and the telescopic rod of the pneumatic push rod is connected to the bottom of the hole.

[0021] By providing a concave hole and arranging the pneumatic push rod part within the concave hole, the height dimension of the whole device can be reduced.

[0022] A further technical solution is that it also includes a controller and a five-position three-way solenoid valve, the pneumatic push rod is electrically connected to the controller through the five-position three-way solenoid valve, and the servo motor is electrically connected to the controller.

[0023] By setting up a controller, the pneumatic push rod and the servo motor can be better connected and coordinated.

[0024] The beneficial effects of the utility model are:

[0025] 1. Efficient cutting function: The pneumatic push rod and piston rod move up and down, in conjunction with the cutting net, to achieve efficient cutting of fruits and vegetables. At the same time, the servo motor controls the cutting speed, and in conjunction with the downward pressure speed of the pneumatic push rod, the size of the cut object can be accurately controlled.

[0026] 2. Versatility: By replacing the cutting frame and the cutting net inside it, you can easily switch between dicing and shredding functions to meet different cutting needs.

[0027] 3. Easy to clean and maintain: By setting grooves, through holes, threaded holes and bolt connection, the installation and disassembly of the equipment is convenient, and the inner wall of the cylinder and the cutting net are flushed, which greatly improves the convenience of cleaning and maintenance of the equipment.

[0028] 4. Compact structure: By setting a concave hole and placing the pneumatic push rod part within the concave hole, the height of the entire equipment is effectively reduced, making the equipment structure more compact.

[0029] 5. By setting the knife entry groove, there is space for the cutter to be inserted, and the bottom of the piston column and the top of the cutting net are in zero distance contact as much as possible, ensuring that the fruits and vegetables are completely cut.
