Description

Technical Field

[0001] The utility model relates to the field of bean product processing, in particular to an automatic stringing machine for coated tofu. Background Art

[0002] Patinated tofu is a delicacy made from soybeans and other foods. The so-called patina means that after the outer layer of the tofu is baked, the inner layer is still slurry. At present, skewers are often inserted into the patinated tofu to facilitate baking. The existing skewering equipment includes a base, and a mold conveying mechanism, a skewer feeding mechanism and a skewer pushing mechanism arranged on the base; the skewer feeding mechanism is provided with a skewer slot; the output end of the skewer pushing mechanism is connected to a top skewer shaft, which is arranged toward the skewer slot, and the skewer pushing mechanism is used to push the top skewer shaft into or out of the skewer slot; the mold conveying mechanism is arranged at one end of the skewer feeding mechanism away from the skewer pushing mechanism, and the conveying direction of the mold conveying mechanism is perpendicular to the length direction of the skewer slot. The utility model can automatically skewer, has high skewering efficiency, is conducive to reducing labor costs, and has high skewering safety.

[0003] The existing skewering equipment has the following problems: the skewering position is not easy to adjust, and due to the special texture of the coated tofu, when the skewering position deviates too far from the center, the tofu may easily break.

[0004] Based on the above situation, an automatic skewering machine for coating tofu is urgently needed to solve the problem that the skewering position is inconvenient to adjust. Utility Model Content

[0005] The utility model aims to solve the problem that the threading position is not easy to adjust in existing skewering equipment and the tofu may be easily broken when the threading position deviates too far from the center due to the special texture of the coated tofu.

[0006] The technical solution of the utility model is as follows:

[0007] An automatic skewering machine for coated tofu, comprising:

[0008] The main conveyor belt is used to transport the coated tofu;

[0009] A string threading mechanism, cooperating with the main conveyor belt and used for string threading;

[0010] The stick delivery mechanism is used to deliver the sticks to the stringing mechanism;

[0011] A height adjustment component is installed on the skewering mechanism and is used to adjust the skewering height.

[0012] The existing skewering equipment is not easy to adjust the skewering position. Due to the special texture of coated tofu, the tofu may easily break if the skewering position deviates too far from the center. In the present solution, the skewer feeding mechanism transports the skewer stick to the skewering mechanism, and the skewering height is adjusted by the height adjustment component to avoid the skewering position deviating too far from the center, thereby solving the problem of the skewering position being difficult to adjust and making the coated tofu more firm after skewering.

[0013] Furthermore, the present solution does not limit the specific structure of the skewering mechanism. One feasible solution is: the skewering mechanism includes a sub-conveyor belt that rotates synchronously with the main conveyor belt, and a push plate driven by a cylinder. When this solution is adopted, since the sub-conveyor belt rotates synchronously with the main conveyor belt, the skewers on the sub-conveyor belt and the coated tofu on the main conveyor belt can move synchronously, thereby ensuring the accuracy of the horizontal position of the skewers.

[0014] Furthermore, the present solution does not limit the specific structure of the height adjustment component. One feasible solution is: the height adjustment component includes a fixed seat and a movable plate installed on the fixed seat, and the movable plate is used to adjust the height of the auxiliary conveyor belt. When this solution is adopted, the height of the auxiliary conveyor belt is adjusted by the movable plate, thereby adjusting the stringing height.

[0015] Furthermore, the present scheme does not solely limit the specific adjustment method of the auxiliary conveyor belt. One feasible scheme is: a fixed rack is formed on the fixed seat, a movable rack is formed on the movable plate, a gear is installed between the fixed rack and the movable rack, and the gear is connected to a lifting rod, and the lifting rod is in contact with the auxiliary conveyor belt. When this scheme is adopted, when the movable plate moves, the moving distance of the gear is always half of the moving distance of the movable plate. When the distance between the movable plate and the fixed seat is the thickness of the coated tofu, the threading position of the skewer stick is exactly located in the center of the coated tofu, thereby ensuring the accuracy of the vertical position of the threading.

[0016] Furthermore, in order to achieve automatic adjustment, one feasible solution is: an infrared generator is installed on the movable plate and a receiver is installed on the main conveyor belt. When this solution is adopted, the distance between the movable plate and the fixed seat can be automatically adjusted to the thickness of the coated tofu through the cooperation of the infrared generator and the receiver.

[0017] Furthermore, the present solution does not limit the specific structure of the stick delivery mechanism. One feasible solution is: a conveying channel is formed in the stick delivery mechanism, and a conveying gear is installed in the conveying channel. When this solution is adopted, the conveying gear can convey the sticks in the conveying channel to the stringing mechanism one by one.

[0018] Compared with the existing technology, the beneficial effects of the utility model are:

[0019] 1. The skewer stick is transported to the skewer stick mechanism by the skewer delivery mechanism, and the skewer stick height is adjusted by the height adjustment component to prevent the skewer stick position from being too far from the center, thereby solving the problem of the skewer stick position being difficult to adjust and making the skewered tofu more solid;

[0020] Second, the skewering mechanism includes a secondary conveyor belt that rotates synchronously with the main conveyor belt, and a push plate driven by a cylinder. When this solution is adopted, since the secondary conveyor belt rotates synchronously with the main conveyor belt, the skewers on the secondary conveyor belt and the tofu wrapped on the main conveyor belt can be moved synchronously, thereby ensuring the accuracy of the horizontal position of the skewers;

[0021] 3. Since a fixed rack is formed on the fixed seat, a movable rack is formed on the movable plate, a gear is installed between the fixed rack and the movable rack, and the gear is connected to a lifting rod, and the lifting rod is in contact with the auxiliary conveyor belt. When the movable plate moves, the moving distance of the gear is always half of the moving distance of the movable plate. When the distance between the movable plate and the fixed seat is the thickness of the coated tofu, the skewering position of the skewer is just located in the center of the coated tofu, thereby ensuring the accuracy of the vertical position of the skewering.

[0033] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0034] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0035] Example:

[0036] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , an automatic skewering machine for coated tofu, comprising:

[0037] A main conveyor belt 1, used for conveying the coated tofu;

[0038] A string threading mechanism 2 cooperates with the main conveyor belt 1 and is used for string threading;

[0039] The stick delivery mechanism 3 is used to deliver the stick 4 to the stringing mechanism 2;

[0040] The height adjustment component 5 is installed on the stringing mechanism 2 and is used to adjust the stringing height.

[0041] The existing skewering equipment is not easy to adjust the skewering position. Due to the special texture of coated tofu, the tofu may easily break if the skewering position deviates too far from the center. In the present solution, the skewer feeding mechanism 3 conveys the skewer stick 4 to the skewering mechanism 2, and the skewering height is adjusted by the height adjustment component 5 to avoid the skewering position deviating too far from the center. This solves the problem of the inconvenient adjustment of the skewering position and can make the coated tofu more firm after skewering.

[0042] Reference Figure 3-Figure 5This solution does not limit the specific structure of the skewering mechanism 2. One feasible solution is: the skewering mechanism 2 includes a sub-conveyor belt 21 that rotates synchronously with the main conveyor belt 1, and a push plate 23 driven by a cylinder 22. When this solution is adopted, since the sub-conveyor belt 21 rotates synchronously with the main conveyor belt 1, the skewers 4 on the sub-conveyor belt 21 can be moved synchronously with the coated tofu on the main conveyor belt 1, thereby ensuring the accuracy of the horizontal position of the skewering.

[0043] Preferably, in this embodiment, a plurality of limiting grooves for limiting the position of the stick 4 are formed on the auxiliary conveyor belt 21 .

[0044] Reference Figure 5 This solution does not limit the specific structure of the height adjustment component 5. One feasible solution is: the height adjustment component 5 includes a fixed seat 51 and a movable plate 52 installed on the fixed seat 51, and the movable plate 52 is used to adjust the height of the auxiliary conveyor belt 21. When this solution is adopted, the height of the auxiliary conveyor belt 21 is adjusted by the movable plate 52, thereby adjusting the threading height.

[0045] The present invention does not limit the specific adjustment method of the auxiliary conveyor belt 21. One feasible solution is as follows: a fixed rack 53 is formed on the fixed seat 51, a movable rack 54 is formed on the movable plate 52, a gear 55 is installed between the fixed rack 53 and the movable rack 54, and the gear 55 is connected to a lifting rod 56, and the lifting rod 56 is in contact with the auxiliary conveyor belt 21. Specifically, in the present embodiment, the lifting rod 56 is in contact with the bottom of the auxiliary conveyor belt 21. When the lifting rod 56 rises, it drives the auxiliary conveyor belt 21 to rise synchronously. When the lifting rod 56 rises, the auxiliary conveyor belt 21 naturally descends under the action of gravity. When this solution is adopted, when the movable plate 52 moves, the moving distance of the gear 55 is always half of the moving distance of the movable plate 52. When the distance between the movable plate 52 and the fixed seat 51 is the thickness of the glazed tofu, the threading position of the skewer stick 4 is just located at the center of the glazed tofu, thereby ensuring the accuracy of the vertical position of the threading.

[0046] In order to realize automatic adjustment, one feasible solution is: an infrared generator 57 is installed on the movable plate 52 and a receiver is installed on the main conveyor belt 1. When this solution is adopted, the distance between the movable plate 52 and the fixed seat 51 can be automatically adjusted to the thickness of the coated tofu through the cooperation of the infrared generator 57 and the receiver.

[0047] Optionally, in this embodiment, a telescopic rod is installed between the fixed seat 51 and the movable plate 52 , and the movable plate 52 is adjusted by controlling the telescopic rod through feedback from the receiver.

[0048] Reference Figure 6This solution does not limit the specific structure of the stick delivery mechanism 3. One feasible solution is: a conveying channel 31 is formed in the stick delivery mechanism 3, and a conveying gear 32 is installed in the conveying channel 31. When this solution is adopted, the conveying gear 32 can convey the sticks 4 in the conveying channel 31 to the stringing mechanism 2 one by one.

[0049] Preferably, a vibration motor and a polarization block driven by the vibration motor are installed in the signature delivery mechanism 3. When this solution is adopted, the polarization block is driven by the vibration motor to vibrate the signature delivery mechanism 3, so that the signature stick 4 can enter the conveying channel 31.

[0050] The working principle of this embodiment:

[0051] The coated tofu is conveyed to the skewering mechanism 2 through the main conveyor belt 1, and at the same time the conveying gear 32 rotates and conveys the skewer sticks 4 one by one to the designated limit grooves on the auxiliary conveyor belt 21. The infrared generator 57 cooperates with the receiver to automatically adjust the distance between the movable plate 52 and the fixed seat 51 to the thickness of the coated tofu. At this time, the skewering position of the skewer stick 4 is located in the center of the coated tofu, and the cylinder 22 drives the push plate to approach the skewer stick 4 and push the skewer stick 4 into the coated tofu to complete the skewering.

[0052] In order to solve the problem that the skewering position is difficult to adjust, in the present solution, the skewer feeding mechanism 3 conveys the skewer stick 4 to the skewering mechanism 2, and the skewering height is adjusted by the height adjustment component 5 to avoid the skewering position from deviating too far from the center, thereby solving the problem that the skewering position is difficult to adjust and making the coated tofu more firm after skewering.

[0053] In order to ensure the accuracy of the horizontal position of the skewers, in the present embodiment, the skewering mechanism 2 includes a sub-conveyor belt 21 which rotates synchronously with the main conveyor belt 1, and a push plate 23 driven by a cylinder 22. When this embodiment is adopted, since the sub-conveyor belt 21 rotates synchronously with the main conveyor belt 1, the skewers 4 on the sub-conveyor belt 21 can move synchronously with the coated tofu on the main conveyor belt 1, thereby ensuring the accuracy of the horizontal position of the skewers.

[0054] In order to ensure the accuracy of the vertical position of the skewer, in the present solution, since a fixed rack 53 is formed on the fixed seat 51, and a movable rack 54 is formed on the movable plate 52, a gear 55 is installed between the fixed rack 53 and the movable rack 54, and the gear 55 is connected to a lifting rod 56, and the lifting rod 56 is in contact with the auxiliary conveyor belt 21. When the movable plate 52 moves, the moving distance of the gear 55 is always half of the moving distance of the movable plate 52. When the distance between the movable plate 52 and the fixed seat 51 is the thickness of the coated tofu, the threading position of the skewer stick 4 is just located at the center of the coated tofu, thereby ensuring the accuracy of the vertical position of the skewer.

[0055] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
