Description

Technical Field

[0001] The utility model relates to the technical field of food machinery, in particular to an automatic turning mechanism for grilled skewers. Background Art

[0002] An automatic grilling machine generally refers to equipment that automatically controls the grilling process and is typically used for grilling food. These devices can have a variety of functions, such as setting the grilling time and temperature, automatically flipping food for even cooking, monitoring food doneness, and spreading ingredients. Current automatic grilling machines typically feature a sprocket-shaped metal plate fixed to the bottom of the skewer, with moving chains installed on both sides of the grill. The chain meshes with the sprocket to achieve the flipping function. This sprocket-chain system is relatively complex, and the chain tension may need to be adjusted during use, which requires high operator skill and increases the difficulty of use. Furthermore, in a grilling environment, the chain and sprockets easily accumulate grease, dust, and food debris, making cleaning difficult and time-consuming. Utility Model Content

[0003] The utility model aims to provide an automatic turning mechanism for skewers, so as to solve the problem that the turning mechanism of existing barbecue machines is relatively complicated and difficult to use.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an automatic flipping mechanism for barbecue skewers, comprising at least one skewer clamping head and a flipping mechanism that drives the skewer clamping head to rotate, the skewer clamping head being used to clamp and fix the barbecue skewers, the flipping mechanism comprising at least one set of transmission gears, a flipping motor that drives each set of transmission gears to rotate, and a mounting shell for the transmission gears; each set of transmission gears comprises at least one transmission gear, which is rotatably mounted on the mounting shell via a rotating shaft, one end of the rotating shaft extending out of the mounting shell and fixedly connected to the skewer clamping head, the other end of the rotating shaft corresponding to at least one transmission gear in each set of transmission gears extending out of the mounting shell and fixedly connected to the flipping motor, and the transmission gears of a single set are meshed with each other.

[0005] The principle of this solution is as follows: first, connect the skewer clamping head with the corresponding rotating shaft, then insert the barbecue skewer into the clamping hole of the skewer clamping head, the barbecue skewer and the clamping hole are loosely matched, and the barbecue skewer is fixed in the clamping hole. Then, start the flip motor, which first drives the rotating shaft directly connected to it to rotate, and then the transmission gear on the rotating shaft drives the transmission gear meshing with it to rotate.

[0006] Advantages of this solution: This solution can control the rotation of the skewer clamping head through a flip motor and a transmission gear, reducing the intermediate transmission structure, making the transmission structure simpler and convenient for accurately controlling the rotation angle of the skewers and performing maintenance; at the same time, through the mutual engagement between a single set of transmission gears, a flip motor can drive multiple transmission gears to rotate, controlling the synchronous flipping of multiple skewers, thereby improving barbecue efficiency and reducing energy consumption; the transmission mechanism is protected by installing a shell.

[0007] Preferably, the mounting housing includes a gear fixing plate and a gear box rear cover, with both ends of the rotating shaft passing through the gear fixing plate and the gear box rear cover, respectively, and the gear fixing plate and the gear box rear cover are fixedly connected. The gear fixing plate and the gear box rear cover protect the transmission gear and reduce the erosion of the transmission gear by oil smoke.

[0008] Preferably, a gear cover is also included, which is used to seal the rotating shaft at the end of the gear fixing plate. When there are fewer skewers, some of the skewer heads are not in use. By fixing the gear cover on the corresponding rotating shaft, the rotating shaft is protected and direct contact with the operator is prevented, which may cause injury to the operator.

[0009] Preferably, the skewer clamp head includes a clamp body, a clamp hole for mounting the barbecue skewers is axially provided at one end of the clamp body, a socket for fixing the barbecue skewers is provided at the contact end between the clamp hole and the barbecue skewers, and a connecting hole for connecting to the rotating shaft is provided at the other end of the clamp body.

[0010] Preferably, the inner wall of the connecting hole is provided with a thread, and the rotating shaft is provided with a thread matching the thread of the connecting hole.

[0011] Preferably, the contact end of the clamping hole and the skewer is provided with a tapered opening, the tapered opening being connected to the clamping hole, the diameter of the tapered opening decreasing from the outside to the inside. The tapered opening facilitates quick alignment of the skewer with the clamping hole and quickly completes the connection between the skewer and the clamping hole.

[0012] Preferably, the inner and outer surfaces of the threaded sleeve are provided with internal and external threads, respectively, and the clamping hole is provided with threads that mate with the threaded sleeve external threads. When the threaded sleeve internal threads rotate with the chuck body, their spiral rotation draws the skewer into the clamping hole, thereby securing the skewer within the clamping hole, preventing the skewer from becoming disengaged from the clamping hole during rotation and simplifying the method of clamping the skewer.

[0013] Preferably, a skewer separation hole is provided on the outside of the clamping hole of the clamp body, which can be used to clamp a skewer with multiple barbecue skewers.

[0014] Preferably, the chuck body with the skewers hole is fixedly connected to the rotating shaft and the output shaft of the flip motor. The skewers with multiple skewers are generally heavy, and the separate flip motor drives the skewers to flip, and the flip speed is controlled in a targeted manner, so that the ingredients are grilled better.

[0015] Preferably, the transmission gears of a single group are arranged linearly. This linear arrangement makes the skewer clamping heads also linear, which is convenient for dispersing the skewers and ensuring a certain distance between the skewers, making it convenient for grilling and controlling the placement and removal of the skewers.

[0018] Figure 3 It is a partial cross-sectional schematic diagram of an embodiment of the present utility model. DETAILED DESCRIPTION

[0019] The following is further described in detail through specific implementation methods:

[0020] The reference numerals in the drawings of the specification include: a clamping head 1, a clamping hole 11, a tapered mouth 12, a flip motor 2, a rotating shaft 3, a transmission gear 4, a bearing 5, a gear tooth cover 6, a gear fixing plate 7, a gear box rear cover 8, and a tooth sleeve 9.

[0021] Example:

[0022] Automatic flip mechanism for skewers, as shown Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, it includes at least one clipping head 1 and a flipping mechanism for driving the clipping head 1 to rotate.

[0023] The skewer holder 1 is used to secure the skewers. It comprises a cylindrical holder body, which facilitates control of the skewer's tilting force and angle, ensuring a smoother grilling process. The cylindrical shape also makes cleaning easier, eliminating corners and hard-to-reach areas. A skewer holder hole 11 is axially defined at one end of the holder body. A threaded cap 9 is located at the contact point between the holder hole 11 and the skewer to secure the skewer.

[0024] The contact end of the clamping hole 11 with the skewer is provided with a tapered opening 12, which communicates with the clamping hole 11. The diameter of the tapered opening 12 decreases from the outside inward. This tapered opening 12 facilitates quick alignment of the skewer with the clamping hole 11, allowing for a quick connection. The section of the clamping hole 11 where the threaded sleeve 9 is mounted is located inside the tapered opening 12. The minimum diameter of the tapered opening 12 is equal to or greater than the diameter of the clamping hole 11, facilitating easy installation of the threaded sleeve 9 into the clamping hole 11.

[0025] The inner and outer surfaces of the threaded sleeve 9 are respectively provided with internal and external threads. The clamping hole 11 is provided with threads that mate with the outer threads of the threaded sleeve 9. The directions of the internal and external threads align with the rotation direction of the skewer holder 1, preventing the threaded sleeve 9 from disengaging from the skewer holder body during rotation. As the internal threads of the threaded sleeve 9 rotate with the skewer holder body, their spiral rotation draws the skewer toward the interior of the clamping hole 11, thereby securing it within the clamping hole 11 and preventing it from disengaging from the clamping hole 11 during rotation. This makes the skewer clamping easier. The threaded sleeve 9 is made of a rigid material and has a groove on one end facing outward for receiving a screwdriver, making it easy to screw the threaded sleeve 9 into the clamping hole 11.

[0026] The flip mechanism includes at least one set of transmission gears, a flip motor 2 that drives each set of transmission gears to rotate, and a mounting housing for the transmission gears 4. In this embodiment, three sets of transmission gears are provided. The spacing between each set of transmission gears can be set according to actual conditions.

[0027] Each transmission gear set includes at least one transmission gear 4. The transmission gears 4 of each set mesh with each other and are arranged linearly. This linear arrangement also forms a linear pattern for the skewer holder 1, facilitating the distribution of the skewers and ensuring a certain distance between them, making it easier to grill and control the placement of the skewers. The number of transmission gears 4 in each set can be adjusted based on actual conditions.

[0028] The transmission gear 4 is rotatably mounted on the mounting housing via the rotating shaft 3. One end of the rotating shaft 3 extends out of the mounting housing and is fixedly connected to the skewer holder 1. In this embodiment, the other end of the skewer holder is provided with a connecting hole for connecting to the rotating shaft 3. The inner wall of the connecting hole is threaded, and the rotating shaft 3 is provided with matching threads. This threaded connection facilitates connection and disassembly. The rotation direction of the skewer is the same as the tightening direction of the rotating shaft 3 and the skewer holder, preventing the skewer holder from separating from the rotating shaft 3 during rotation.

[0029] The other end of the rotating shaft 3 corresponding to at least one transmission gear 4 in each group of transmission gears extends out of the mounting shell and is fixedly connected to the flip motor 2. A flip motor 2 can drive multiple transmission gears 4 to rotate, thereby controlling the synchronous flipping of multiple skewers, which has higher barbecue efficiency and lower energy consumption.

[0030] The mounting housing includes a gear retaining plate 7 and a gearbox rear cover 8. The rotating shaft 3 extends through both ends of the gear retaining plate 7 and the gearbox rear cover 8, respectively. The rotating shaft 3 is rotatably connected to the gear retaining plate 7 via bearings 5. The gear retaining plate 7 and the gearbox rear cover 8 are fixedly connected. The gear retaining plate 7 and the gearbox rear cover 8 protect the transmission gear 4 from oil smoke. The gear retaining plate 7 and the gearbox rear cover 8 are detachably connected, specifically by bolts. In this embodiment, the rotating shaft 3 is rotatably mounted on the gear retaining plate 7 via bearings 5.

[0031] The device also includes a gear cover 6, which is located at the end of a gear fixing plate 7 and serves to seal the rotating shaft 3. When a small number of skewers are being used and some of the skewer holders 1 are not in use, the gear cover 6 is secured to the corresponding rotating shaft 3 to protect the shaft 3 and prevent direct contact between the shaft 3 and the operator, which could result in injury. In this embodiment, the gear cover 6 is fixedly connected to the rotating shaft 3 via a threaded connection. In this embodiment, a gear cover 6 can also be installed on the transmission gear 4 connected to the flipping motor 2, corresponding to the end of the rotating shaft 3 near the skewer holder 1. This minimizes the impact of the skewers on the flipping motor 2's speed, making it easier to control the flipping speed of the skewers.

[0032] The overturning motor 2 that drives each group of transmission gears to rotate is connected to the transmission gear 4 in the middle of the corresponding group. In this way, when the middle transmission gear 4 rotates, the transmission gears 4 on both sides are synchronously meshed with the transmission gears 4 on both sides, and the overturning speed of the skewers is faster.

[0033] Some chuck bodies have separate holes outside the clamping hole 11, allowing for holding multiple skewers. The chuck body with the separate holes is fixedly connected to the output shaft of the flip motor 2, corresponding to the rotating shaft 3. Skewers with multiple skewers are generally heavy, and a separate flip motor 2 drives the skewers to flip, allowing for targeted control of the flipping speed and achieving better grilling results.

[0034] The specific implementation process is as follows:

[0035] First, connect the skewer clamping head 1 with the corresponding rotating shaft 3, install the gear tooth cover 6 on the rotating shaft 3 without the skewer clamping head 1, and then insert the barbecue skewer into the clamping hole 11 of the skewer clamping head 1. The barbecue skewer and the clamping hole 11 are clearance-matched, and the barbecue skewer is fixed in the clamping hole 11. Then start the flip motor 2. First, the flip motor 2 drives the rotating shaft 3 directly connected to it to rotate, and then the transmission gear 4 on the rotating shaft 3 drives the transmission gear 4 engaged with it to rotate. The transmission gear 4 rotates linearly in sequence, so that one flip motor 2 drives multiple skewer clamping heads 1 to rotate. When the internal thread of the socket 9 rotates with the chuck body, its spiral rotation pulls the barbecue skewer into the clamping hole 11, and then fixes the barbecue skewer in the clamping hole 11 to prevent the barbecue skewer from being separated from the clamping hole 11 during rotation. The way of clamping the barbecue skewer is simpler.

[0036] In this solution, the transmission gear 4 is arranged linearly, and the transmission structure is simpler. One flip motor 2 drives multiple skewer clamping heads 1 to rotate, making it easier to evenly control the flipping speed of the skewers and lowering energy consumption. The skewers are fixed by the clearance between the skewers and the clamping holes 11, which makes the structure simpler and the installation and disassembly speeds faster. The internal thread of the socket 9 is used to pull the skewers into the clamping holes 11 when the skewer clamping heads 1 rotate, preventing the skewers from being separated from the clamping holes 11 during rotation. The transmission gear 4 is protected by the gear fixing plate 7 and the gear box rear cover 8, minimizing the influence of the barbecue environment on the transmission structure and extending its service life.
