Moreover, it requires manual work for stringing on and off; Tabletop automatic barbecue equipment, one type realizes electric flipping, but still generates fumes, which are only removed by exhaust ventilation. The production capacity is low; Another type uses the principle of an automatic rotating sun gear to achieve automatic flipping of the skewers, and also suppresses the generation of smoke from the source by allowing oil droplets to drip onto the bottom oil tray during heating. However, the production capacity and power are relatively small, and manual work is required for stringing on and off, which is suitable for home-style tabletop barbecue; The automatic flipping barbecue invented by Italians realizes rapid manual stringing on, automatic flipping, and relatively large-scale baking, but it cannot suppress the generation of smoke, and the judgment of taste and degree of ripeness is arbitrary by hand without a standard process; Drawer-type automatic barbecue: realizes a controllable process for degree of ripeness and taste, and also suppresses the generation of smoke, but the production capacity is relatively low, and the oil from the upper layer of skewers will drip onto the lower layer of skewers, and if they are different varieties of skewers, they will definitely have a flavor mix.

[0043] The following further details a skewer clamping device and a smokeless automatic barbecue machine proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following description and the claims, the advantages and features of the present invention will be clearer.

[0044] Embodiment 1

[0045] Refer to Figure 1 and Figure 4, this embodiment provides a skewer clamping device 2, including: a first transmission member 22, a rotating member 23, an elastic member 21, a fixing member 24, and a clamping member 26;

[0046] The fixing member 24 is sleeved on the rotating member 23 and is rotatably connected to the rotating member 23. One end of the rotating member 23 is fixedly connected to the first transmission member 22. An installation hole is provided at the other end of the rotating member 23. One ends of the elastic member 21 and the clamping member 26 are both arranged in the installation hole. One end of the elastic member 21 is connected to the installation hole, and the other end of the elastic member 21 is connected to the clamping member 26. The clamping member 26 slides along the direction of the installation hole, and a skewer hole is provided in the clamping member 26 along the direction of the installation hole;

[0047] Among them, the clamping member 26 has a sliding tendency towards the outside of the installation hole under the elastic force of the elastic member 21. Along the sliding tendency direction, the inner wall surface of the circumferential side of the installation hole and the outer wall surface of the end side of the clamping member 26 arranged in the installation hole are both arranged in a tightened manner and are mutually extruded under the elastic force of the elastic member 21; in the mutually extruded state, the skewer hole is in a tightened state. Overcoming the elastic force of the elastic member 21, the clamping member 26 slides into the installation hole, and the skewer hole is in a relaxed state.

[0048] Preferably, a plurality of steel balls 25 evenly distributed at the same level are further provided on the circumferential side of the skewer hole in the clamping member 26. Preferably, a guiding member 27 is further provided. The guiding member 27 is connected to one end of the clamping member 26 far from the rotating member 23. Along the insertion direction of the skewer hole, the guiding member 27 is provided with a guiding surface for insertion guiding.

[0049] Now, a detailed description of this embodiment 1 is given:

[0050] Refer to Figure 1 , this embodiment is used for clamping skewers. This embodiment includes: a first transmission member 22, a rotating member 23, an elastic member 21, a fixing member 24, and a clamping member 26;

[0051] In this embodiment, the elastic member 21 is a compressed spring, which provides a downward elastic pressure to the clamping member 26. Therefore, the clamping member 26 has a sliding tendency towards the outside of the installation hole. However, due to being blocked by the rotating member 23 and receiving the supporting force of the rotating member 23, an inward pressure is generated on the clamping member 26. When the skewer is inserted, the pressure provided by the clamping member 26 helps the skewer to be fixed; when the clamping member 26 is lifted, a gap is generated between the clamping member 26 and the rotating member 23, resulting in the disappearance of the inward pressure of the clamping member 26, and the fixed skewer will fall off. In addition, a plurality of steel balls 25 are provided in the clamping member 26, and the sliding of the steel balls 25 helps the bamboo skewer to be inserted smoothly; at the same time, when the clamping member 26 is lifted, under the action of the gravity of the skewers and the rolling of the steel balls 25, the skewers fall off.

[0052] In this embodiment, the first transmission member 22 is respectively connected to the rotating member 23 and the elastic member 21, and the first transmission member 22 drives this embodiment to rotate self - rotatably; since the fixing member 24 is rotationally connected to the rotating member 23 by bearings, when the rotating member 23 rotates, the fixing member 24 remains stationary. This embodiment also has a guiding member 27, and the guiding member 27 is connected to one end of the clamping member 26 away from the rotating member 23. Along the insertion direction of the skewer hole, there is a guiding surface for insertion guiding, which improves the efficiency of feeding skewers for roasting.

[0053] In this embodiment, the roasting skewer is locked when inserted and disengaged when pressed and lifted, which is convenient for feeding and discharging roasted skewers; the roasting skewer clamping device can rotate self - rotatably, driving the roasting skewer to rotate self - rotatably, with uniform heating, without manual flipping of the roasted skewers, reducing the labor intensity of workers.

[0054] Embodiment 2

[0055] This embodiment provides a smokeless automatic barbecue machine based on Embodiment 1, and this device uses the roasting skewer clamping device 2 in any one of Embodiments 1.

Among them, the first transmission member 22 is a gear, the second transmission member 8 is a rack, and the rack and the gear are in meshing transmission to realize the self - rotation of the rotating member 23.

[0057] Among them, the transmission mechanism 1 includes a transmission belt and a motor, the motor is used to drive the transmission belt to rotate around the furnace body 10, and the conveyor belt is used to drive the moving connectors 17 to move along the conveyor belt.

[0058] Now, a detailed description of Embodiment 2 is given:

[0059] The main structure of this embodiment consists of a base 9 and a furnace body 10, with the furnace body 10 mounted on the base 9. The transmission mechanism 1 includes a motor and a drive belt. The drive belt is mounted around the furnace body 10, and the motor drives the drive belt to rotate around the furnace body 10. The motor's transmission speed is controllable. Multiple movable connectors 17 are evenly distributed on the drive belt, each of which is equipped with a corresponding skewer clamping device 2. As the motor drives the drive belt, the skewer clamping device 2 rotates simultaneously, grilling the skewers held by the skewer clamping device 2.

[0060] In this embodiment, the first transmission member 22 is a gear of the skewer clamping device 2, and the second transmission member 8 is a rack; the racks are arranged on both sides of the oven body 10 near the heating portion. The racks and gears are meshed for transmission, and the transmission belt drives the skewer clamping device 2. The gear and the rack move relative to each other. Since the rack is fixed, the gear rotates and drives the rotating member 23 to rotate together, so that the skewer clamping device 2 can realize the function of self-rotation, and the heating is more uniform during the grilling process.

[0061] See Figure 2 In one embodiment, the heating part includes: an infrared heating tube 5 and a heating mounting plate 4, the infrared heating tube 5 is detachably connected to the heating mounting plate 4, and the heating mounting plate 4 is hinged to the base 9.

[0062] Likewise, in another embodiment, the heating portion may further include a heating box and a heating mounting plate 4 , wherein the heating box and the heating mounting plate 4 are detachably connected, and the heating box is used to place barbecue fuel, such as charcoal fire.

[0063] In this embodiment, the heating mounting plate 4 is arranged on both sides of the base 9. Since the heating mounting plate 4 and the base 9 are hingedly connected, the heating mounting plate 4 can be flipped over; the infrared heating tube 5 is arranged in the heating mounting plate 4 for grilling skewers, and the working temperature of the infrared heating tube 5 is controlled between 260 and 300 degrees; when the power is insufficient, the infrared heating tube 5 can be replaced by a heating box, and the heating box can be detachably connected to the heating mounting plate 4 by pulling, snapping, magnetic attraction, etc. Preferably, the heating box can be pulled out in any direction along the heating mounting plate 4, and a handle can be provided along the pulling direction of the heating box; since the infrared heating tube 5 and the heating box are detachably connected, it is convenient to clean the heating mounting plate 4 and keep the device tidy and clean; the infrared heating tube 5 is used to reduce the generation of oil smoke during the baking process. In addition, the infrared heating tube 5 can be started to peak power or extinguished immediately in just 2 seconds, saving energy and being convenient and quick to use; the heating box can be used when the power is insufficient, which reduces the restriction range of the use conditions of this embodiment.

[0064] See Figure 3, in this embodiment, it further includes an automatic feeding mechanism 14. The automatic feeding mechanism 14 is arranged on one side of the furnace body 10 and is used to automatically string the roasting skewers of the skewer clamping device 2. Among them, the automatic feeding mechanism 14 is a manipulator, and the manipulator is also provided with a scanning module. The scanning module is used to identify the barbecue information on the roasting skewers and transmit it to the control unit 13. The control unit 13 is also used to control the transmission mechanism 1 and the heating unit to perform corresponding barbecue operations according to the barbecue information.

[0065] In this embodiment, the roasted skewers are strung at the automatic feeding mechanism 14. The automatic feeding mechanism 14 is a manipulator, which is used for automatic stringing. The roasting skewers of the roasted skewers are inserted into the clamping member 26, and it can also arrange the roasted skewers after roasting and put them into the blanking buffer area 16. The blanking buffer area 16 has a heat preservation storage function; the identification module of the manipulator can identify the bar code on the special string bamboo skewers to judge the type of the string and transmit the information to the control unit 13. The control unit 13 makes the barbecue machine execute the process corresponding to the to-be-roasted roasted skewers, such as: heating temperature and roasting time.

[0066] See Figure 2 and Figure 4 , in this embodiment, it further includes an automatic blanking mechanism 3. The automatic blanking mechanism 3 is arranged on one side of the furnace body 10 and is used to automatically lift the clamping member 26 of the skewer clamping device 2. Among them, in one implementation manner, the automatic blanking mechanism 3 includes a lifting member 31 and a lifting driving part. The lifting driving part is a cylinder drive or a hydraulic drive or a motor drive, and is used to drive the lifting member 31 to automatically lift and lower.

[0067] Similarly, in another implementation manner, the automatic blanking mechanism 3 may further include: a lifting member 31, a pressing member 33 and a lever connecting member 32. One end of the lever connecting member 32 is connected to the lifting member 31, and the other end of the lever connecting member 32 is connected to the pressing member 33; the end of the pressing member 33 away from the lever connecting member 32 is located on the movement path of the moving connecting member 17; the moving connecting member 17 is driven by the transmission mechanism 1 to push the pressing member 33 downward, and the pressing member 33 presses downward to lift the lifting member 31 through the lever connecting member 32, so as to realize the automatic lifting of the clamping member 26.

[0068] In this embodiment, the automatic blanking mechanism 3 is arranged at one end of the furnace body 10. After the grilled skewers are rotated one week after baking, they will automatically fall off through the automatic blanking mechanism 3. The automatic blanking mechanism 3 includes a pressing member 33, a lifting member 31 and a lever moving connecting member 17. The pressing member 33 is arranged on the movement path of the moving connecting member 17. When the moving connecting member 17 touches the pressing member 33, the pressing member 33 is pressed down under the pushing of the moving connecting member 17, and the lifting member 31 is lifted upward through the lever moving connecting member 17. The lifting member 31 presses the clamping member 26, and the grilled skewers automatically fall off. When the clamping mechanism passes through the automatic blanking mechanism 3, the clamping member 26 slides down under the action of gravity and the elasticity of the elastic member 21 and returns to the state before lifting, and can re-load skewers. In addition, the lifting member 31 can also be lifted by means of cylinder drive, hydraulic drive or motor drive.

[0069] See Figure 2 and Figure 6 , preferably, a dipping trough 7 is further arranged on the base 9, and the dipping trough 7 is arranged on one side of the furnace body 10. In this embodiment, the dipping trough 7 is made of food-grade 304 stainless steel and has a heating function, and the temperature is controlled at about 80 degrees. When the baking reaches half of the stroke, the grilled skewers are transported to the dipping trough 7 through the transmission mechanism 1. Through the cooperation of the guide plate 18 and the skewer clamping device 2, the grilled skewers are lifted and then lowered into the dipping trough 7 to dip the sauce. At this time, the skewers are in a semi-cooked state, and the slightly dry surface is conducive to absorbing the sauce. Then, the grilled skewers are lifted and restored to the baking state and continue to move forward.

[0070] See Figure 2 , preferably, an oil receiving trough 6 is further arranged on the base 9, and the oil receiving trough 6 is located at the bottom of the heating space. In this embodiment, the oil receiving trough 6 has a water circulation function. When the oil drops, it falls into the cold water and will not produce oil fumes, which can inhibit the generation of oil fumes from the source. At the same time, the circulating water also has the function of purifying and cooling the oil.

[0071] See Figure 3 and Figure 5 , preferably, an oil fume treatment mechanism is further provided. The oil fume treatment mechanism includes an oil fume collection fan 11 and an oil fume purification device 12. The oil fume collection fan 11 is arranged on the top of the furnace body 10, and the output end of the oil fume collection fan 11 is connected to the oil fume purification device 12. In this embodiment, when food is heated, gas will evaporate. The trace fumes generated during baking are inhaled into the pipeline by the oil fume collection fan 11 and become purified gas after being filtered by the oil fume purification device 12 and can be directly discharged, achieving an environmentally friendly and smokeless effect, protecting the health of the staff and the environmental hygiene.

[0072] See Figure 2 and Figure 3, baking process of this embodiment: Manually pre-place the skewers from the refrigerated area into the feeding buffer area 15; then the manipulator grabs the grilled skewers. During the skewer loading process, the barcode sensor of the manipulator will read and identify the variety of the skewers on the skewer, and upload the result to the control unit 13 and select the corresponding baking process. In addition, the control unit 13 has an information interaction function to collect data such as the quantity, variety, and machine failure problems of the grilled skewers during the baking process of the barbecue machine; under the action of the transmission mechanism 1 and the rack, the skewer clamping device 2 is driven, so that the grilled skewers rotate while walking, and the rotation effect is similar to the repeated turning during manual charcoal baking to make the skewers evenly heated; during the baking process, the heating unit is used to heat the grilled skewers; when baking to half of the stroke, the grilled skewers will automatically lift up and soak into the dipping sauce tank, then automatically lift up and then return to the baking state and continue to move forward; at the end of baking, through the automatic blanking mechanism 3, the automatic separation of the grilled skewers is realized under the combined action of the blanking mechanism and the transmission mechanism 1; then the manipulator grabs and transfers them to the buffer heat preservation area for storage in sequence, and the baking process ends.

[0073] In this embodiment, since an infrared heating tube is used for heating, the generation of oil fumes is reduced. In addition, the electric baking can reach the peak power or be instantly extinguished in only 2 seconds, solving the problems of difficult ignition in charcoal barbecue and waste caused by the inability to extinguish the charcoal in time; when the power is insufficient, it can be replaced with a heating box and use barbecue fuel for heating, reducing the limitation range of the use conditions of this embodiment; an oil receiving tank is provided, and a water circulation function is added to the oil receiving tank. When the oil drips down and falls into the cold water, it will not produce smoke, suppressing the generation of oil fumes from the source. The circulating water can also purify and cool the oil, further reducing the generation of oil fumes; in addition, the oil fume collection fan and the oil fume purification equipment can process the generated trace oil fumes, reduce environmental pollution, and achieve the effect of environmental protection and smokelessness;
