Description

Technical Field

[0001] The utility model relates to the technical field of quick-freezing food processing of prefabricated dishes, in particular to a conveyor for quick-freezing food processing of prefabricated dishes. Background Technique

[0002] Quick-frozen food of prefabricated dishes refers to food that has been prepared or processed and is quickly cooled to a very low temperature through quick-freezing technology during the production process, so as to maintain the freshness and nutritional components of the food. However, a conveyor can automatically transport the prepared or processed food to the quick-freezing area, reducing manual handling and improving production efficiency.

[0003] For traditional conveyors for quick-freezing food processing of prefabricated dishes, the output shaft of a single-chip motor is usually fixedly connected to the driving roller at the starting end of the conveyor. The rotation of the output shaft of the motor drives the driving roller to rotate. The driving roller transmits power to the conveyor belt through direct contact with the conveyor belt, causing the conveyor belt to start moving, and the remaining evenly distributed rollers support the weight of the conveyor belt, reducing friction and helping to keep the conveyor belt running smoothly.

[0004] Traditional conveyors for quick-freezing food processing of prefabricated dishes have the following problems: During the quick-freezing food processing, sometimes it is necessary to keep the food staying for a certain period of time in some links. Since the motor of the traditional conveyor continuously rotates to drive the conveyor belt, it is difficult to achieve processing steps that require precise time control, which may affect the freezing effect and quality of prefabricated dishes. For this reason, we propose a conveyor for quick-freezing food processing of prefabricated dishes. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a conveyor for quick-freezing food processing of prefabricated dishes, which can accurately control the staying time of prefabricated dishes in the quick-freezing area, ensure that each batch of food is evenly frozen, and thus significantly improve the stability and production quality of the conveyor for quick-freezing food processing of prefabricated dishes, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A conveyor for quick-freezing food processing of prefabricated dishes, including a mounting frame and an intermittent motion mechanism;

[0007] Mounting frame: A plurality of evenly distributed rollers are rotatably connected between the front and rear inner walls thereof.

The front end of the rotating shaft is fixedly sleeved with a round block. The right end of the outer surface of the round block is provided with teeth, and the teeth are fitted and installed with the tooth grooves, which can accurately control the residence time of the prefabricated dishes in the quick-freezing area, ensure that each batch of food is evenly frozen, and thus significantly improve the stability and production quality of the conveyor for prefabricated dish quick-freezing food processing.

[0009] Furthermore, it also includes a single-chip microcomputer. The single-chip microcomputer is arranged at the right end of the front side of the mounting frame, and the input end of the single-chip microcomputer is electrically connected to an external power supply, which is convenient for regulating the operation of each electrical appliance.

[0010] Furthermore, it also includes legs. The number of legs is four. The top ends of the four legs are fixedly connected to the adjacent ends of the lower surface of a mounting frame. The bottom ends of the four legs are all installed with universal wheels through bolts to realize the movement of the mounting frame.

[0011] Furthermore, the intermittent motion mechanism also includes circular positioning grooves. The circular positioning grooves are all opened on the outer surface of the turntable. The circular positioning grooves are circumferentially misaligned with the tooth grooves, and the circular positioning grooves are all fitted and installed with a round block, providing accurate stopping points.

[0012] Furthermore, it also includes a housing. The housing is fixedly connected to the left end of the front side of the mounting frame, which is convenient for protecting the intermittent motion mechanism from damage.

[0013] Furthermore, the intermittent motion mechanism also includes a driving mechanism. The driving mechanism includes a worm gear and a worm. The worm is rotatably connected between the left and right inner walls of the housing. The worm gear is fixedly sleeved on the front end of the rotating shaft. The worm gear is located on the front side of the round block.

The left end of the output shaft of the motor is fixedly connected to the right end of the worm. The input end of the motor is electrically connected to the output end of the single-chip microcomputer to drive the intermittent motion mechanism.

[0015] Compared with the prior art, the beneficial effects of the present utility model are: The conveyor for prefabricated dish quick-freezing food processing of the present invention has the following advantages:

[0016] Place the prefabricated dishes on the conveyor belt. Control the operation of the motor through a single-chip microcomputer. The motor drives the worm and the worm gear to rotate, and then drives the turntable and the roller, so that the conveyor belt starts to move. The rotation of the turntable is controlled by the meshing of the teeth on the round block and the tooth grooves on the turntable, ensuring that the conveyor belt stops temporarily when the round block rotates 180 degrees and then continues to move. In this way, the prefabricated dishes can stay in the quick-freezing area for enough time to ensure uniform freezing, improving the stability and production quality of the conveyor for processing prefabricated quick-frozen foods.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , this embodiment provides a technical solution: A conveyor for processing prefabricated quick-frozen foods, including a mounting frame 1 and an intermittent motion mechanism 4;

[0025] Mounting frame 1: There are evenly distributed rollers 8 rotatably connected between its front and rear inner walls. The rollers 8 on the leftmost and rightmost sides are drivingly connected by a conveyor belt 2. The rollers 8 in the middle are all in contact with the inner wall surface of the conveyor belt 2. After reaching the quick-freezing area, the pre-prepared dishes are placed on the upper surface of the conveyor belt 2. It also includes a single-chip microcomputer 7, which is arranged at the right end of the front side of the mounting frame 1. The input end of the single-chip microcomputer 7 is electrically connected to an external power supply. It also includes legs 5, and the number of legs 5 is four. The tops of the four legs 5 are fixedly connected to the adjacent ends of the lower surface of a mounting frame 1. Universal wheels 6 are installed at the bottoms of the four legs 5. The mounting frame 1 is pushed to the quick-freezing area through the universal wheels 6. It also includes a housing 3, which is fixedly connected to the left end of the front side of the mounting frame 1;

[0026] Intermittent motion mechanism 4: It includes a turntable 41, tooth grooves 42, a rotating shaft 44, a round block 46, and teeth 47. The turntable 41 is fixedly sleeved on the front end of the leftmost roller 8. The outer surface of the turntable 41 is provided with evenly distributed tooth grooves 42. The rotating shaft 44 is rotatably connected to the left end of the front side of the mounting frame 1. The front end of the rotating shaft 44 is fixedly sleeved with a round block 46. The right end of the outer surface of the round block 46 is provided with teeth 47. The teeth 47 are fitted and installed with the tooth grooves 42. The intermittent motion mechanism 4 further includes circular positioning grooves 43, which are all opened on the outer surface of the turntable 41. The circular positioning grooves 43 are all circumferentially offset from the tooth grooves 42. The circular positioning grooves 43 are all fitted and installed with a round block 46. The intermittent motion mechanism 4 further includes a driving mechanism 45. The driving mechanism 45 includes a worm gear 451 and a worm 453. The worm 453 is rotatably connected between the left and right inner walls of the housing 3. The worm gear 451 is fixedly sleeved on the front end of the rotating shaft 44. The worm gear 451 is located on the front side of the round block 46. The worm gear 451 is meshed and connected with the worm 453. The driving mechanism 45 further includes a motor 452. The motor 452 is installed on the right side of the housing 3 by bolts. The left end of the output shaft of the motor 452 is fixedly connected to the right end of the worm 453. The input end of the motor 452 is electrically connected to the output end of the single-chip microcomputer 7. By controlling the operation of the motor 452 through the single-chip microcomputer 7, the output shaft of the motor 452 rotates to drive the worm 453 to rotate. The worm 453 meshes and rotates with the worm gear 451, causing the rotating shaft 44 to start rotating. The rotating shaft 44 drives the round block 46 to rotate and drives the teeth 47 on its outer surface to mesh with the tooth grooves 42 on the turntable 41, causing the turntable 41 to start rotating. The rotation of the turntable 41 drives the leftmost roller 8 to rotate. The leftmost roller 8 is driven by the conveyor belt 2 to the rightmost roller 8, causing the other rollers 8 to also start rotating, so that the conveyor belt 2 starts to convey the prefabricated dishes. When the round block 46 rotates 180 degrees, the teeth 47 on its outer surface are separated from the adjacent tooth grooves 42 on the turntable 41. At this position, the outer surface of the round block 46 contacts the circular positioning groove 43 and rotates within the circular positioning groove 43, which causes the turntable 41 to stop rotating, and the conveyor belt 2 will also temporarily stop operating. When the round block 46 continues to rotate and separates from the circular positioning groove 43, the teeth 47 on the round block mesh with the tooth grooves 42 at another position on the turntable 41 again, which causes the turntable 41 to start rotating again and drives the conveyor belt 2 to continue conveying. Through this intermittent conveying mode, the prefabricated dishes can stay in the quick-freezing area for enough time, ensuring that the prefabricated dishes in the freezing unit can be evenly frozen, thus guaranteeing the quality and freezing effect of the products.

[0027] The working principle of a conveyor for processing prefabricated frozen food provided by the present utility model is as follows: First, the mounting frame 1 is pushed to the quick-freezing area through the universal wheels 6. After reaching the quick-freezing area, the prefabricated dishes are placed on the upper surface of the conveyor belt 2. Then, the single-chip microcomputer 7 is used to control the operation of the motor 452. The output shaft of the motor 452 rotates to drive the worm 453 to rotate. The worm 453 meshes with the worm wheel 451 to rotate, so that the rotating shaft 44 starts to rotate. The rotating shaft 44 drives the round block 46 to rotate, and drives the teeth 47 on its outer surface to mesh with the tooth grooves 42 on the turntable 41, so that the turntable 41 starts to rotate. The rotation of the turntable 41 drives the leftmost roller 8 to rotate. The leftmost roller 8 is driven by the conveyor belt 2 to the rightmost roller 8, so that the other rollers 8 also start to rotate, thereby enabling the conveyor belt 2 to convey the prefabricated dishes. When the round block 46 rotates 180 degrees, the teeth 47 on its outer surface are separated from the adjacent tooth grooves 42 on the turntable 41. At this position, the outer surface of the round block 46 contacts the circular positioning groove 43 and rotates within the circular positioning groove 43, which causes the turntable 41 to stop rotating and the conveyor belt 2 to temporarily stop operating. When the round block 46 continues to rotate and separates from the circular positioning groove 43, the teeth 47 on the round block mesh with the tooth grooves 42 at another position on the turntable 41 again, which causes the turntable 41 to start rotating again and drives the conveyor belt 2 to continue conveying. Through this intermittent conveying mode, the prefabricated dishes can stay in the quick-freezing area for enough time, ensuring that the prefabricated dishes in the freezing unit can be evenly frozen, thus guaranteeing the quality and freezing effect of the product.

[0028] It should be noted that the specific model of the single-chip microcomputer 7 disclosed in the above embodiments is STM32F207VCT6, and the motor 452 is preferably selected as D180M-0160030B-E. The single-chip microcomputer 7 controls the operation of the motor 452 by using the commonly used methods in the prior art.

[0029] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
