Description

Technical Field

[0001] The utility model relates to the technical field of rice distribution machine equipment, in particular to a post-disk conveyor mechanism of a rice distribution machine. Background Technique

[0002] With the development of the times, kitchen catering equipment is becoming more and more automated. In order to achieve rapid meal distribution, automatic meal distribution equipment has been gradually introduced into people's daily lives and has been developed.

[0003] The Chinese patent application number is CN201822136788.5, which discloses a rice distribution machine, a plate conveyor and a rice distribution device, and a plate placement, conveyor and rice distribution device. The automatic plate placing device can be set on the plate station at the starting point of the conveyor of the plate conveyor. The automatic plate distribution device is provided with a spiral mechanism. Users can put the plates into the spiral mechanism of the automatic plate distribution device in advance. The spiral rolls down all the time, and the plates are in a waiting state. When a plate drops down and enters the plate conveyor device, the plate conveyor device can then automatically convey the plate under the rice distribution machine, and the rice distribution machine automatically distributes rice to the plate, and then automatically conveys the plate after rice distribution to the dishwashing assembly line, realizing the full automation of the meal distribution assembly line. However, the disclosed spiral plate distribution device in this solution occupies a large area and can only distribute one plate at a time, with low plate distribution efficiency. The disclosed plate conveyor device in this solution can also only convey one plate at a time, with low conveying efficiency, and cannot meet the needs of the high-speed development of the existing industry. Moreover, due to the three-dimensional nature of the spiral, the placement surface of the plate is not on a horizontal plane, so the placement of the plate in the spiral mechanism is not stable. During the actual working process, the plate is likely to roll along with the rolling of the spiral mechanism, thus prone to problems of inaccurate positioning. In addition, the disclosed automatic plate placing device in this patent has low interchangeability among rice distribution machines in the same field and is very inconvenient to disassemble during actual use. Therefore, it is also very inconvenient to clean the equipment.

Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1-8 , in the embodiment of the present invention, a conveying mechanism after the plate dropping of a rice distributing machine includes an automatic plate dropping assembly 100 and a conveying assembly 200. The conveying assembly 200 is arranged below the automatic plate dropping assembly 100. The automatic plate dropping assembly 100 includes a fixing plate assembly 10, a driving mechanism 20, a first driven mechanism 30, a second driven mechanism 40 and a protective cover assembly 50. The fixing plate assembly 10, the driving mechanism 20, the first driven mechanism 30 and the second driven mechanism 40 are all arranged inside the protective cover assembly 50. The conveying assembly 200 includes a chain plate assembly 210 and a driving assembly 220. The driving assembly 220 is connected to the chain plate assembly 210 and drives the chain plate assembly 210 to perform a reciprocating conveying movement.

[0028] Preferably, in the above-mentioned conveying mechanism after the plate dropping of a rice distributing machine, the fixing plate assembly 10 includes a motor fixing plate 1 and a turbine fixing plate 2. The fixing plate assembly 10, the driving mechanism 20 and the first driven mechanism 30 are symmetrically distributed in 2 groups. Each group of the first driven mechanisms 30 is respectively connected to 2 groups of the second driven mechanisms 40. The 2 groups of the second driven mechanisms 40 are respectively used to complete the plate separation and plate dropping of the left and right plate eaves of the dinner plate during the plate dropping process. During the plate separation and plate dropping process, both the left and right sides are carried out simultaneously and synchronously, so as to ensure that the downward forces received by both sides of the dinner plate are the same, that is, the plate separation and plate dropping process is stable.

[0029] Preferably, for the post-disk conveyor mechanism of a meal distribution machine as described above, the drive mechanism 20 includes a motor 21, a first driving wheel 22, a support column 23, a support column fixing member 24, and a disk separation induction disk 25. The motor 21 is fixedly arranged at the bottom of the motor fixing plate 1. The output shaft of the motor 21 passes through the motor fixing plate 1 and is fixedly connected to the first driving wheel 22. The motor 21 drives the driving wheel 22 to rotate through its output shaft, thereby driving the first driven mechanism 30 to rotate. The support column 23 and the support column fixing member 24 are symmetrically distributed on the left and right sides of the bottom of the motor fixing plate 1, and two groups are respectively arranged. One end of the support column 23 is fixed on the support column fixing member 24, and the other end is fixedly connected to the motor fixing plate 1. The support column 23 and the support column fixing member 24 serve as a support structure to help support and fix the overall turbine-type automatic disk dropping mechanism. By driving in or removing screws, the installation or disassembly of the support column fixing member on the equipment can be achieved. Also, by setting the height of the support column, the height adjustment of the overall mechanism can be completed. In the meal distribution machines of the same field, the interchangeability is high, and the cleaning, installation, and maintenance of the equipment are simple. A sensor disk fixing block 26 is arranged on one side of the first driving wheel 22. The disk separation induction disk 25 is fixedly arranged on the sensor disk fixing block 26 and is located above the first driving wheel 22. The disk separation induction disk 25 is used to receive the disk separation signal and instruct the motor 21 to rotate, and start to separate the dinner plates.

[0030] Preferably, for the post-disk conveyor mechanism of a meal distribution machine as described above, the first driven mechanism 30 is symmetrically distributed on the left and right sides of the top of the motor fixing plate 1 and is set to two groups. Each group respectively includes a first driven wheel 31 and a first synchronous belt 32. The first driven wheel 31 is arranged on the left or right side of the top of the motor fixing plate 1. The first synchronous belt 32 bypasses the first driving wheel 22 and the first driven wheel 31 and is meshed and connected with the first driving wheel 22 and the first driven wheel 31. The first synchronous belts 32 in the two groups of first driven mechanisms 30 symmetrically distributed on the left and right sides of the top of the motor fixing plate 1 are respectively distributed up and down and bypass the driving wheel 22. This setting enables the first driven wheel 31 to rotate synchronously with the driving wheel 22, thereby driving the second driven mechanism 40 to rotate.

[0031] Preferably, in the above-mentioned post-plate conveying mechanism of the rice dispensing machine, two groups of second driven mechanisms 40 are symmetrically distributed on both sides of each group of the driving mechanism 20, and each group of the second driven mechanisms 40 includes multiple turbines 41, turbine transmission wheels 42, turbine synchronous belts 43, plate guide rods 44, first guide fixing seats 45 and second guide fixing seats 46. The turbine 41 passes through and is fixedly set at the bottom of the turbine fixing plate 2, and the turbine transmission wheel 42 is set at the top of the turbine fixing plate 2 and is connected to the turbine 41 through the rotating shaft on the turbine 41. The multiple turbine transmission wheels 42 and the turbine transmission wheel 42 and the first driven wheel 31 are all connected through the turbine synchronous belt 43, so that the turbine transmission wheel 42 can achieve synchronous rotation with the first driven wheel 31, thereby driving the turbine 41 to rotate and complete the plate dispensing work. The plate guide rod 44 is fixedly arranged on the first guide fixing seat 45 or the second guide fixing seat 46, and a first plate drop area 61 and a second plate drop area 62 are formed between the plurality of turbines 41 and the plate guide rod 44. Through the design of the first plate drop area 61 and the second plate drop area 62, it is possible to complete the drop of two plates at a time, thereby effectively improving the drop efficiency of the overall mechanism. When dropping the plates, the plates are vertically separated along the direction of the plate guide rod 44, and the plates are stably dropped after being separated without deviation.

[0032] Preferably, in the above-mentioned post-plate-dropping conveying mechanism of the rice dispensing machine, the turbine 41 includes a turbine connecting shaft 411 and a wheel body 412, the turbine connecting shaft 411 is arranged on the top of the wheel body 412, and the wheel body 412 is spirally provided with a spiral groove 413 along its outer wall from the upper end face to the lower end face, a plate-dropping end 414 is formed between the spiral groove 413 and the outer wall and upper end face of the wheel body 412, and a plate-dropping end 415 is formed between the spiral groove 413 and the outer wall and lower end face of the wheel body 412. When separating plates, the turbine 41 keeps rotating and circulating. When the turbine 41 rotates until the upper end surface of the separating plate end 414 is located at the lower end surface of the plate brim of the first plate at the bottom, a motion connection is generated between the plate brim and the turbine 41, which causes the plate brim to move downward as the turbine 41 continues to rotate until it enters the spiral groove 413, thereby completing the separation of the plates. As the turbine 41 continues to rotate, the plate brim continues to move downward along the spiral groove 413, and the plate brim will leave the spiral groove 413 and reach the plate drop end 415. The turbine 41 continues to rotate, and the motion connection between the plate brim and the turbine 41 is lost, thereby completing the plate drop. Since the entire action from separating plates to dropping plates is more or less completed in the turbine, the turbine not only performs the operations of separating and dropping plates, but also limits the range of motion of the plates, thereby making the entire separation and dropping process more accurate, safe, and stable.

[0033] Preferably, for the post-dish-dropping conveying mechanism of the above-mentioned rice distributing machine, the protective cover assembly 50 includes two first protective covers 51 and two second protective covers 52 that are horizontally and vertically spaced apart. The first protective covers 51 and the second protective covers 52 are sequentially connected end to end in pairs to form a rectangular frame. The motor fixing plate 1 and the turbine fixing plate 2 are respectively sleeved at the bottoms of the first protective covers 51 and the second protective covers 52. This design makes the overall mechanism safer, simpler and more beautiful.

[0034] Preferably, for the post-dish-dropping conveying mechanism of the above-mentioned rice distributing machine, the chain plate assembly 210 includes a plurality of chain plates 2101 arranged horizontally in parallel, a second driving wheel 2102 and a second driven wheel 2103. A plurality of plate blocking blocks 2104 are evenly spaced on the chain plate 2101. The distance between adjacent plate blocking blocks 2104 can be determined according to the length of the plate. The plate blocking blocks 2104 are mainly used to limit the position of the plate in the length direction and prevent the plate from shifting during the conveying process. The chain plate 2101 bypasses the second driving wheel 2102 and the second driven wheel 2103 and is meshed and connected with the second driving wheel 2102 and the second driven wheel 2103. During the conveying process of the plate, the chain plate 2101 makes a reciprocating conveying movement along the second driving wheel 2102 and the second driven wheel 2103, so as to complete the conveying of the plate from dish dropping to the rice distribution and blanking of the rice distributing machine.

[0035] Preferably, for the post-dish-dropping conveying mechanism of the above-mentioned rice distributing machine, the driving assembly 220 includes a conveying main shaft 2201, a conveying transmission shaft 2202, a driving motor 2203, a speed reducer 2204 and a transmission chain 2205. A plurality of second driven wheels 2103 sequentially pass through and are fixed on the conveying transmission shaft 2202, and a plurality of second driving wheels 2102 sequentially pass through and are fixed on the conveying main shaft 2201. One end of the conveying main shaft 2201 is provided with a first gear 2206. The output end of the driving motor 2203 is connected to the speed reducer 2204. The output end of the speed reducer 2204 is provided with a second gear 2207. The transmission chain 2205 bypasses the first gear 2206 and the second gear 2207 and is meshed and connected with the first gear 2206 and the second gear 2207. The driving motor 2203 drives the speed reducer 2204 and the second gear 2207 to make a rotational movement, thereby driving the transmission chain 2205, the first gear 2206 and the conveying main shaft 2201 to make a rotational movement, and further driving the second driving wheel 2102, the chain plate 2101, the second driven wheel 2103 and the conveying transmission shaft 2202 to make a rotational movement, so as to complete the conveying of the plate from dish dropping to the rice distribution and blanking of the rice distributing machine. The use of the speed reducer 2204 helps the driving motor 2203 reduce the transmission error during deceleration and reduce the production cost of the product.

[0046] Working principle:

[0047] The working principle of the automatic plate dropping assembly is as follows: through the design of the first plate dropping area 61 and the second plate dropping area 62, it is possible to complete the separation and dropping of two plates at one time; when the plate separation sensor plate 25 receives the plate separation signal, it instructs the motor 21 to rotate and start separating the plates. The motor 21 drives the driving wheel 22 to rotate through its output shaft, thereby driving the first driven wheel 31, the turbine transmission wheel 42 and the turbine 41 to rotate, thereby completing the work of separating the plates; when separating the plates, the turbine 41 keeps rotating and circulating. When the turbine 41 rotates until the upper end surface of the separating end 414 is located at the lower end surface of the eaves of the first plate at the bottom, a motion connection is generated between the eaves of the plate and the turbine 41, which makes the eaves of the plate move downward as the turbine 41 continues to rotate until it enters the spiral groove 413, thereby completing the work of separating the plates; as the turbine 41 continues to rotate, the eaves of the plate continue to move downward along the spiral groove 413, and the eaves of the plate will separate from the spiral groove 413 and reach the plate dropping end 415. The turbine 41 continues to rotate, and the motion connection between the eaves of the plate and the turbine 41 is lost, thereby completing the work of dropping the plates. The turbine 41 rotates one circle to complete the work of separating and placing a plate. When the work of placing the previous plate is completed, the work of separating and placing the second plate will be immediately carried out, and this cycle will be repeated until the work of separating and placing the plates in the entire rice dispensing machine is completed.

[0048] The working principle of the conveying assembly is: the drive motor 2203 drives the reducer 2204 and the second gear 2207 to rotate, thereby driving the transmission chain 2205, the first gear 2206 and the conveying main shaft 2201 to rotate, and then driving the second driving wheel 2102, the chain plate 2101, the second driven wheel 2103 and the conveying drive shaft 2202 to rotate, thereby completing the transportation of the meal plate from the placement of the plate to the dispensing of the rice dispensing machine.

[0049] The above detailed description is for the specific description of a feasible embodiment of the present utility model. However, the embodiment is not used to limit the patent scope of the present utility model. Any equivalent implementation or modification made without departing from the technical spirit of the present utility model should be included in the patent scope of this case.
