[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Please also refer to Figures 1 to 6 The present invention provides a device for stringing block foods, which is described below. The device comprises a conveyor 1 and two sets of loading platforms 2. The conveyor 1 is suitable for conveying block foods 5 in a straight line. The conveyor 1 has a conveyor belt 11 for circulating transmission. The conveyor belt 11 is provided with a plurality of groups of receiving slots 12 at intervals along its length. The length direction of the receiving slots 12 is along the width direction of the conveyor belt 11. The receiving slots 12 are provided with a plurality of slots 13 arranged in a string and suitable for placing block foods 5. The plurality of slots 13 are interconnected, and the slots 13 near the two sides of the conveyor belt 11 are connected to the receiving slots 12. On the side of the conveyor belt 11, the minimum width of the accommodating groove 12 is greater than the diameter of the bamboo stick 6. The conveyor 1 has an input end 14 and an output end 15. The conveying direction of the conveyor belt 11 is from the input end 14 to the output end 15; two groups of material holding tables 2 are used to hold block foods 5, which are respectively arranged on both sides of the conveying direction of the conveyor 1. The material holding tables 2 are suitable for pouring block foods 5 onto the conveyor 1. After the block foods 5 are placed on the conveyor belt 11, they fall into the accommodating groove 12. The block foods 5 located on the conveyor belt 11 and moved to the output end 15 are arranged in multiple groups of strings.

[0040] The present invention provides a device for stringing block foods. Compared with the prior art, a conveyor 1 is provided to accommodate multiple block foods 5, which is conducive to the automatic arrangement of the block foods 5 into a string. When the block foods 5 fail to automatically form a string, manual operation can be used to move the block foods 5 into the corresponding receiving grooves 12, thereby solving the technical problems of high labor intensity and low efficiency of the manual operation of arranging the block foods 5 into a string before stringing. The device can put the block foods 5 into the receiving grooves 12 to form a string, thereby helping to improve the efficiency of the manual operation of arranging the block foods 5 into a string and reducing labor intensity.

[0041] The two groups of material holding platforms 2 in the present embodiment are located on both sides of the conveyor belt 11, and their height is greater than the height of the conveyor belt 11, so as to facilitate pouring the block food 5 onto the conveyor belt 11. The block food 5 poured onto the conveyor belt 11 can automatically fall into the receiving groove 12, and then be arranged in a string. When there is block food 5 that does not fall into the receiving groove 12, it can be operated manually at this time. If some block food 5 falls into or half falls into the receiving groove 12 (tank body 13) in a tilted or skewed shape, it can be manually centered, aligned, etc. This utility model greatly improves the efficiency of the block food 5 stringing operation, and helps to manually string. When the conveyor belt 11 transports the block food 5 and arrives at the output end 15, that is, as the conveyor belt 11 is slowly transported, the block food 5 is manually straightened or filled into the receiving groove 12 at the same time. At this time, when the block food 5 arrives at the output end 15, most of the block food 5 can be arranged in a string. When there are fewer bulk foods 5 on the conveyor belt 11, the loading platform 2 can be flipped to allow the bulk foods 5 to be poured onto the conveyor belt 11. In this embodiment, the length of the conveyor belt 11 is greater than the length of the loading platform 2, which is located near the input end 14. The depth of the receiving groove 12 is consistent with the thickness or height of the bulk foods 5, or slightly lower than the thickness or height of the bulk foods 5. When the bulk foods 5 in a string arrive at the output end 15, bamboo sticks 6 can be used to string the multiple bulk foods 5 together (either manually or using a machine). To facilitate the passage of the bamboo sticks 6 through the receiving groove 12, the ends of the receiving groove 12 are extended to the sides of the conveyor belt 11. The bamboo sticks 6 are inserted into the receiving groove 12 from a position below the height of the upper end of the conveyor belt 11, allowing multiple bulk foods 5 to be skewered simultaneously. After stringing, the bamboo sticks 6 and the multiple bulk foods 5 can be removed from the receiving groove 12. In this embodiment, each groove body 13 is used to hold one bulk food 5.

[0042] In order to realize that the conveyor belt 11 can accommodate a plurality of block foods 5 while rotating and can arrange the block foods 5 into strings, in some embodiments, refer to Figures 1 to 6 The conveyor belt 11 includes multiple hinged plates 16 connected end to end along its length, forming a closed structure. The receiving slots 12 are formed on the hinged plates 16. Along the length of the conveyor belt 11, the ends of the hinged plates 16 are hingedly connected to the adjacent hinged plates 16. This connection method is similar to that of crawler belts or plate chains in the prior art. Through the circulation of the multiple hinged plates 16 connected end to end, multiple groups of block-shaped food products 5 arranged in a string shape can be moved, and when they reach the output end 15, they can be easily threaded.

[0043] In order to satisfy the requirement of threading different types of block foods 5, in some embodiments, please refer to Figures 1 to 6The top view of the trough 13 is square, circular, oval, rectangular or diamond-shaped. If the trough 13 is diamond-shaped or square, it can accommodate fish tofu; if it is round, it can accommodate meatballs, etc. When the block food 5 is filled with multiple troughs 13, it is convenient to thread them later. Figure 6 The fish tofu is contained in the groove body 13 and is pierced by the bamboo sticks 6 to form a string of fish tofu.

[0044] In some embodiments, see Figures 1 to 6 The conveyor 1 includes a lifting frame 17, a driving roller 18, a driven roller 19, and a drive motor. The lifting frame 17 has the freedom to rise and fall in the height direction. The driving roller 18 is arranged horizontally and is rotatably connected to one end of the lifting frame 17. The driven roller 19 is arranged horizontally and is rotatably connected to the other end of the lifting frame 17. The conveyor belt 11 is wrapped around the driving roller 18 and the driven roller 19. The drive motor is connected to the lifting frame 17, and the power output end 15 is in power transmission connection with the driving roller 18. The drive motor is used to drive the driving roller 18 to rotate, thereby driving the conveyor belt 11 to rotate. The rotation speed of the conveyor belt 11 is controlled by the speed of the drive motor. In this embodiment, the rotation speed of the conveyor belt 11 is relatively slow. By adjusting the height of the lifting frame 17, the height of the conveyor belt 11 can be adjusted to match the height of the material receiving platform 2. The lifting frame 17 can be of existing technology, and its height is adjustable and can be locked after adjustment.

[0045] In some embodiments, see Figures 1 to 6 The material table 2 includes a support frame 21 and a material table 22. The material table 22 is located at the upper end of the support frame 21 and is hingedly connected to the lifting frame 17 and the support frame 21. The upper end of the material table 22 is used to hold the block food 5. The material table 22 has the freedom to flip in the direction close to or away from the conveyor belt 11. After flipping the material table 22, the block food 5 is poured onto the conveyor belt 11 from the side close to the conveyor belt 11. The top view structure of the material table 22 is rectangular, with its long side located close to the conveyor belt 11. The side of the material table 22 close to the conveyor belt 11 is not provided with a baffle, while the other three sides are provided with baffles 23. The block food 5 is located at the upper end of the material table 22 and is surrounded by three baffles 23. The block food 5 will not fall from the material table 22. When the material table 22 flips, the block food 5 can automatically fall onto the conveyor belt 11 from the side close to the conveyor belt 11. In actual operation, according to the amount of block food 5 placed on the conveyor belt 11 , each group of the holding tables 2 can be appropriately used to pour the block food 5 onto the conveyor belt 11 .

[0046] In order to realize automatic pouring of block food 5 onto the conveyor belt 11, in some embodiments, refer to Figures 1 to 6The side of the feeding platform 22 closest to the conveyor belt 11 is hingedly connected to the lifting frame 17. The support frame 21 is a telescopic rod hinged to the bottom of the side of the feeding platform 22 facing away from the conveyor belt 11. The telescopic rod is used to push the feeding platform 22 to tilt. By controlling the extension and retraction of the telescopic rod, the tilting angle of the feeding platform 22 can be controlled. When the feeding platform 22 is not tilted, it is horizontal. When it is tilted, the side away from the conveyor belt 11 faces upward. In other words, the telescopic rod extends, pushing the feeding platform 22 to rotate. The food blocks 5 on the feeding platform 22 are then automatically dropped onto the conveyor belt 11. By controlling the tilting angle of the feeding platform 22, the amount of food blocks 5 poured onto the conveyor belt 11 can be controlled. It is important to note that there is a gap between the feeding platform 22 and the conveyor belt 11. The width of this gap is smaller than the length, width, height, or diameter of the food blocks 5, meaning that the food blocks 5 will not fall through this gap. If some food blocks 5 do not fall onto the conveyor belt 11, manual assistance can be used. The telescopic rod in this embodiment is conventional and conveniently adjustable. Preferably, the telescopic rod is an electric telescopic rod. A controller 3 is provided on the conveyor 1. This controller 3 is electrically connected to the telescopic rod and controls its extension length, thereby controlling the tilting angle of the feeding table 22 and the amount of block food 5 poured onto the conveyor belt 11.

[0047] In order to reduce the workload of manually moving the block food 5 into the receiving groove 12, in some embodiments, refer to Figures 1 to 6 The device for stringing block foods also includes a material shifting assembly 4 , which is used to shift the block foods 5 on the conveyor belt 11 into the interior of the receiving groove 12 .

[0048] In some embodiments, see Figures 1 to 6The material diverter assembly 4 includes a telescopic column 41, a crossbeam 42, a chute 43, a telescopic rod 44, and a diverter tooth 45. The telescopic column 41 is vertically arranged and has the freedom to extend and retract along its axial direction. The telescopic column 41 can be adjusted in length. One end of the crossbeam 42 is fixedly connected to the upper end of the telescopic column 41, and the other end is a cantilever end. The crossbeam 42 is horizontally arranged. The chute 43 is located at the bottom end of the crossbeam 42 and extends along the length of the crossbeam 42. The chute 43 is slidably connected to a slider 46, which has the freedom to slide along the length of the chute 43. The telescopic rod 44 is vertically arranged and has the upper end connected to the slider 46. The telescopic rod 44 has the freedom to extend and retract along its axial direction. The diverter tooth 45 is connected to the lower end of the telescopic rod 44 and is used to divert the block food 5 on the conveyor belt 11 into the receiving tank 12. The telescopic column 41 is a conventional product and can be an electric telescopic column. It is electrically connected to the controller 3 and its operation is controlled by the controller 3. In this embodiment, the conveyor 1 is also electrically connected to the controller 3 and its operation is controlled by the controller 3. A base 47 is provided at the lower end of the telescopic column 41. The base 47 can stably support the telescopic column 41 and always keep the telescopic column 41 in an upright position to ensure stable operation of the material-diverting tooth 45. By controlling the expansion and contraction of the telescopic column 41 and the sliding of the slider 46, the diverting position of the material-diverting tooth 45 can be adjusted, thereby automatically diverting the block food 5 into the receiving groove 12. The diverting of the material-diverting tooth 45 can reduce the labor intensity of manual operation. The diverting of the material-diverting tooth 45 is similar to the manual diverting action of the hand, and the movement trajectory of the material-diverting tooth 45 can be pre-set on the controller 3. The controller 3 includes a PLC control chip, control circuit, control buttons, etc., and is electrically connected to the material-diverting assembly 4 to automatically divert the block food 5 into the receiving groove 12. The material-selecting teeth 45 are elastic and have a structure similar to that of a comb. The material-selecting teeth 45 include a plurality of teeth arranged in an array, and the distance between the teeth is smaller than the length, width or height of the block food 5. That is, the block food 5 to be selected by the material-selecting teeth 45 can be selected, while the block food 5 located inside the receiving groove 12 cannot be selected by the material-selecting teeth 45 (the material-selecting teeth 45 are elastic and will not select the block food 5 located in the receiving groove 12 out of the receiving groove 12).

[0049] The telescopic rod 44 in this embodiment is a conventional electric telescopic rod electrically connected to the controller 3. When controlled, it automatically extends and retracts, thereby adjusting the height of the feed tooth 45. By controlling the movement distance of the feed tooth 45, the food blocks 5 on the conveyor belt 11 can be properly moved so that the food blocks 5 fall into the receiving groove 12.

[0050] In some embodiments, see Figures 1 to 6The lower end of the telescopic rod 44 is connected to an electric rotating platform 48, which has a circumferential degree of freedom of rotation. The upper end of the material-selecting tooth 45 is connected to the lower end of the electric rotating platform 48 and can be rotated and adjusted by the electric rotating platform 48. The electric rotating platform 48 is conventional and is electrically connected to the controller 3 and its operation is controlled by the controller 3. By controlling the rotation of the material-selecting tooth 45, the food block 5 can be selected to any direction to move the food block 5 into the receiving groove 12.

[0051] In order to realize the automatic reciprocating movement of the material-selecting teeth 45 to push the block food 5 into the receiving groove 12, in some embodiments, refer to Figures 1 to 6 A long through hole 49 is formed in the middle of the crossbeam 42 from its upper end to the lower end. The long through hole 49 is set inside the slide 43. A pusher 410 is set at the upper end of the crossbeam 42. The pushing top of the pusher 410 is connected to a lever 411 for passing through the long through hole 49. The pusher 410 is suitable for pushing the pusher lever 411 to move within the long through hole 49. The lower end of the lever 411 is connected to the slider 46 to push the slider 46 to slide. The pusher 410 includes a motor, a driving wheel, a driven wheel, and a conveyor belt wrapped around the driving wheel and the driven wheel. Reference can be made to the existing technology. The lower end of the conveyor belt is connected to the lever 411. The moving length of the conveyor belt is less than the length of the long through hole 49, which can realize the movement of the lever 411, thereby automatically pushing the slider 46 to slide and automatically shifting the material selection tooth 45. The pusher 410 is electrically connected to the controller 3 and its operation is controlled by the controller 3.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
