Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a stone mill trough cleaning device for sesame seeds. Background Technology

[0002] Stone mills, as traditional food processing tools, are still widely used in the production of products such as sesame paste. Their unique grinding method effectively preserves the flavor and nutrients of the ingredients. During the grinding of sesame seeds, because sesame seeds are rich in oil, a thick, difficult-to-remove residue adheres to the inner wall of the stone mill after processing.

[0003] To ensure food safety and hygiene, and to prevent cross-contamination between different batches of products, the stone mill troughs must be thoroughly cleaned after each production run. Currently, most manufacturers rely on manual cleaning, which is not only labor-intensive and time-consuming, but also often leaves cleaning blind spots when dealing with oily dirt, making it difficult to achieve ideal cleanliness standards and posing potential risks to food safety.

[0004] To address the drawbacks of manual cleaning, the industry has considered installing fixed mechanical cleaning devices on stone mills. However, the stone mill trough serves as both a material channel and a finished product collection area during grinding. Any cleaning structure fixed near or inside the trough would directly hinder the normal grinding of sesame seeds and the smooth discharge of the finished product, making the entire production process difficult to operate normally. This functional structural conflict makes it difficult to apply and promote automated cleaning devices on traditional stone mill equipment.

[0005] Therefore, this utility model proposes a stone mill trough cleaning device for sesame seeds to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the difficulties in cleaning the existing stone mill troughs for sesame seeds, and the fact that automated cleaning devices are difficult to apply due to their obstruction of the grinding production process, this utility model aims to provide a sesame stone mill trough cleaning device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a stone mill trough cleaning device for sesame seeds, including a base and a stone mill trough body fixedly connected to the base; the device also includes a cleaning mechanism and an avoidance mechanism installed inside the base.

[0008] The cleaning mechanism includes a housing, which is driven and slidably connected to the base via a clearance mechanism. A motor is fixedly connected inside the housing, and a rotating rod is fixedly connected to the output shaft of the motor. A guide rail is also fixedly connected inside the housing, and a sliding rack is slidably connected to the guide rail. A slider is fixedly connected to the sliding rack, and the slider is rotatably connected to the end of the rotating rod. This combination converts the rotational motion of the motor into the linear reciprocating motion of the sliding rack.

[0009] Furthermore, a sliding rack plate is engaged with a gear, which is fixedly connected to a cleaning plate via a rotating shaft. A cleaning brush for scrubbing the main body of the stone mill trough is fixedly connected to the cleaning plate. Through the meshing of the gear and rack, the linear reciprocating motion of the sliding rack plate is converted into the reciprocating oscillation of the cleaning brush, thereby achieving automated mechanical scrubbing of the inner wall of the stone mill trough.

[0010] Preferably, to ensure the stability and accuracy of the internal transmission of the cleaning mechanism, a slide rail is fixedly connected inside the housing, a sliding rack plate is slidably mounted on the slide rail, a rotating shaft is rotatably connected to the bottom of the housing through a bearing seat, and a motor is fixedly connected inside the housing through a bearing seat. These support and guiding structures ensure the smooth operation of each moving part.

[0011] Preferably, the cleaning mechanism also includes a cleaning component, which includes a high-pressure nozzle fixedly connected to the chassis. The high-pressure nozzle sprays towards the interior of the stone mill trough body, and is used to perform high-pressure water rinsing while mechanically brushing, so as to achieve a combination of brushing and rinsing and improve cleaning efficiency and cleanliness.

[0012] Preferably, the avoidance mechanism includes a second motor fixedly mounted in the base via a motor mounting bracket, a second rotating shaft fixedly connected to the output shaft of the second motor, a second gear fixedly connected to the second rotating shaft, a second sliding rack meshing with the second gear, and the end of the second sliding rack fixedly connected to the bottom of the housing, thus forming a power transmission device for driving the overall translation of the cleaning mechanism.

[0013] Preferably, to ensure the stability of the avoidance mechanism transmission, the second rotating shaft is rotatably connected to the base through the third shaft seat, providing reliable support for the rotation of the second rotating shaft.

[0014] Preferably, the chassis is also connected to a telescopic belt. The telescopic belt is used to cover the sliding groove formed on the base when the chassis slides, which can play a role in dust prevention and protection of internal transmission components, and extend the service life of the equipment.

[0015] Preferably, to form a complete grinding device, the device also includes a support frame, which is fixedly connected to the base; a guide hopper is fixedly connected to the support frame, and the guide hopper is connected to the stone mill feed port set on the stone mill body through a feed pipe. The stone mill body is set inside the stone mill trough body, together forming a complete material grinding path.

[0016] Preferably, a discharge guide plate located below the main body of the stone mill trough is also fixedly connected to the base for convenient collection of the ground product. Furthermore, the cleaning brush is a cylindrical nylon brush, which combines good wear resistance and flexibility, effectively removing residue without damaging the inner surface of the stone mill trough.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of high labor intensity, low efficiency, and difficulty in thoroughly removing oily residues in the manual cleaning of stone mill troughs in the prior art by setting up a cleaning brush driven by a motor and linked by a rotating rod, slider, sliding rack plate and gears for reciprocating brushing, and cooperating with a high-pressure nozzle for rinsing. It achieves the technical effect of automated and deep cleaning of stone mill troughs, effectively ensuring the hygiene standards of food production.

[0019] 2. This utility model, by setting an avoidance mechanism, can drive the entire cleaning mechanism to slide along the guide rail to an avoidance position away from the stone mill trough when sesame grinding is required. This solves the problem of spatial interference and impact on normal production process caused by the cleaning device during grinding and discharge. It achieves the technical effect of seamless switching and non-interference between grinding and cleaning processes, and significantly improves the automation level and overall production efficiency of the equipment.

[0020] 3. This utility model integrates the cleaning mechanism and the avoidance mechanism into the main body of the sesame stone mill equipment, resulting in a compact overall structure and ingenious design. The cleaning action and the avoidance action are controlled by two independent motors, with clear functional division and simple operation. This solves the problem of the traditional equipment having a scattered structure and requiring manual intervention to assist in the installation or relocation of the equipment, thus achieving the technical effect of improving the integration of the equipment and the convenience of use.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Reference Figures 1 to 5 This utility model provides a stone mill trough cleaning device for sesame seeds, which aims to solve the problems of difficult stone mill trough cleaning and the cleaning device hindering grinding production in the prior art.

[0031] The sesame stone mill trough cleaning equipment includes a base 1 and a stone mill trough body 2 fixedly connected to the base 1. The equipment also includes a cleaning mechanism 6 and a clearance mechanism 7 installed inside the base 1. The housing 61 of the cleaning mechanism 6 is driven and slidably connected to the base 1 through the clearance mechanism 7, thereby realizing the clearance and repositioning of the cleaning mechanism 6 relative to the stone mill trough body 2.

[0032] The cleaning mechanism 6 is used for automated cleaning of the stone mill trough body 2. Its core transmission structure is located inside the housing 61. A motor 62, which serves as the power source, is fixedly connected inside the housing 61. A rotating rod 63 is fixedly connected to the output shaft of the motor 62. A guide rail 64 is also fixedly connected inside the housing 61. A sliding rack plate 65 is slidably connected to the guide rail 64. In order to convert the rotational motion of the motor 62 into the linear reciprocating motion of the sliding rack plate 65, a slider 696 is fixedly connected to the sliding rack plate 65. The slider 696 is rotatably connected to the rotating rod 63. The end of the crank-connecting rod mechanism is formed. When the motor 62 drives the rotating rod 63 to rotate, the slider 696 drives the sliding rack plate 65 to slide back and forth on the guide rail 64. In order to convert the linear reciprocating motion into reciprocating oscillation, the sliding rack plate 65 is meshed with a gear 66. The gear 66 is fixedly connected to the cleaning plate 68 through the rotating shaft 67. The cleaning plate 68 is fixedly connected with a cleaning brush 691 for directly brushing the stone mill trough body 2. Through this series of transmission relationships, the automatic reciprocating oscillation brushing of the cleaning brush 691 in the stone mill trough body 2 is realized.

[0033] A slide rail 692 is fixedly connected inside the housing 61. A sliding rack plate 65 is slidably mounted on the slide rail 692. The slide rail 692 provides stable support and precise guidance for the linear reciprocating motion of the sliding rack plate 65, preventing it from deflecting or shaking during meshing transmission. A rotating shaft 67 is rotatably connected to the bottom of the housing 61 through a bearing seat 693. The bearing seat 693 provides reliable support for the rotation of the rotating shaft 67 and the gear 66, ensuring smooth meshing transmission. A motor 62 is fixedly connected inside the housing 61 through a bearing seat 694. The bearing seat 694 provides a stable mounting base for the motor 62, ensuring the stability of power output.

[0034] The cleaning mechanism 6 also includes a cleaning component 69, which includes a high-pressure nozzle 695 fixedly connected to the housing 61. The high-pressure nozzle 695 sprays towards the inside of the stone mill trough body 2. While the cleaning brush 691 performs mechanical brushing, the high-pressure nozzle 695 can spray high-pressure water to powerfully rinse the inner wall of the stone mill trough body 2, achieving a synergistic effect of brushing and rinsing and improving the cleaning effect.

[0035] The obstacle avoidance mechanism 7 includes a second motor 71 fixedly installed in the base 1 via a motor mounting bracket 76. The output shaft of the second motor 71 is fixedly connected to a second rotating shaft 72. A second gear 73 is fixedly connected to the second rotating shaft 72. The second gear 73 meshes with a second sliding rack plate 74. The end of the second sliding rack plate 74 is fixedly connected to the bottom of the housing 61. The second motor 71 drives the second gear 73 to rotate, thereby driving the second sliding rack plate 74 to make linear motion, ultimately realizing the translation of the entire housing 61. The structure has reliable transmission and accurate positioning. To ensure the stable rotation of the second rotating shaft 72, the second rotating shaft 72 is rotatably connected to the base 1 via a third shaft seat 75.

[0036] The chassis 61 is also connected to a telescopic belt 77, which is used to cover the sliding groove formed on the base 1 when the chassis 61 slides. This effectively prevents external dust or debris from entering the sliding mechanism, ensuring smooth sliding and extending the service life of the equipment.

[0037] The support frame 5 is fixedly connected to the base 1. The guide hopper 10 is fixedly connected to the support frame 5. The guide hopper 10 is connected to the stone mill feed port 8 set on the stone mill body 4 through the feed pipe 9. The stone mill body 4 is set inside the stone mill trough body 2. The sesame raw material enters the stone mill through this path for grinding. In order to collect the ground product, the base 1 is also fixedly connected to the discharge guide plate 3 located below the stone mill trough body 2. In order to achieve a better cleaning effect, the cleaning brush 691 is preferably a cylindrical nylon cleaning brush 691, which is wear-resistant and does not easily damage the inner surface of the stone mill trough body 2.

[0038] The implementation principle of this application embodiment is as follows: A sesame stone mill trough cleaning device mainly consists of a stone mill trough body 2 placed on a base 1, a stone mill body 4 on the stone mill trough body 2, and a cleaning mechanism 6 connected to the base 1. Two identical devices are mirror images of each other. A support frame 5 is connected to the base 1 of the two identical devices. A guide hopper 10 is connected above the support frame 5, and a discharge guide plate 3 is fixedly connected below it. The discharge cone of the guide hopper 10 is connected to the stone mill feed inlets 8 installed on both sides of the stone mill body 4 through the feed pipe 9. An avoidance mechanism 7 is installed inside the base 1.

[0039] The operator first puts sesame seeds into the feed hopper 10. The sesame seeds enter the mill feed inlet 8 on the main body 4 of the mill through the feed pipe 9 and finally enter the inside of the mill. The operator starts the mill and rotates the grinding disc to begin grinding. At this time, the cleaning mechanism 6 slides to the side of the main body 2 of the mill through the avoidance mechanism 7, away from the mill trough, so as not to interfere with the sesame processing and discharge. The finished sesame product is discharged from the mill discharge port. After collection, the processing process is completed. The power source of the mill is turned off. After confirming that the mill has completely stopped, the operator resets the cleaning mechanism 6 to the cleaning position through the avoidance mechanism 7. When cleaning begins, the operator starts the motor 62 installed in the machine box 61 through the shaft seat 694 in the cleaning component 69. The drive shaft of the motor rotates, driving the rotating rod 63 rotatably connected to the shaft to rotate. When the rotating rod 63 rotates, the slider 696 rotatably connected to the rotating rod 63 is... The mechanism drives the sliding rack plate 65, which is connected to the guide rail 64, to slide back and forth in the guide rail 64 and slide in the slide rail 692. The sliding of the sliding rack plate 65 drives the gear 66, which meshes with it, to rotate. This causes the cleaning plate 68, which is connected to the gear 66 via the rotating shaft 67, to swing back and forth. This causes the cylindrical nylon cleaning brushes 691, which are connected to both ends of the cleaning plate 68, to swing back and forth along the bottom of the stone mill trough body 2, cleaning the inside of the stone mill trough body 2. The rotating shaft 67 is rotatably connected to the bearing seat 693, and the bearing seat 693 is fixedly connected to the bottom of the machine box 61. Then, the operator connects the water supply pipe to the high-pressure nozzle 695. The cleaning water is sprayed out through the high-pressure nozzle 695 to rinse the inside of the stone mill trough body 2. Combined with the back and forth swinging of the cleaning brushes 691 to scrub the inside of the stone mill trough body 2, the cleaning effect of the stone mill trough is achieved.

[0040] When the operator needs to start the stone mill for grinding sesame seeds, the operator starts the second motor 71, which is installed inside the base 1 and mounted inside the base 1 via the motor mounting bracket 76 in the avoidance mechanism 7. When the second motor 71 starts, the drive shaft of the second motor 71 drives the rotating shaft 72 connected to it to rotate, causing the two identical gears 73 connected to the rotating shaft 72 to rotate. This causes the two identical sliding rack plates 74 meshing with the gears 73 to move backward. The sliding rack plates 74 are connected to the housing 61 in the cleaning mechanism 6. The movement of the sliding rack plates 74 causes the housing 61 connected to them to slide backward. During the sliding, the telescopic belt 77 on the sliding groove installed on the housing 61 retracts. When the cleaning mechanism 6 is slid away from the main body 2 of the stone mill, the operator... Turn on the power source of the stone mill to start grinding the sesame seeds. After the sesame processing is completed and the finished product is collected, the operator turns off the stone mill. When cleaning is required, the operator starts the motor to make gear 2 73 and shaft 2 72 rotate through the motor shaft, which drives the sliding rack plate 2 74 that meshes with it to slide forward, so that the machine box 61 connected to the sliding rack plate 2 74 returns to the working position. The telescopic belt 77 extends and retracts to protect the exposed part inside the sliding groove. Shaft 2 72 is rotatably connected through bearing seat 3 75 and connected to the drive shaft of motor 2 71. After the cleaning mechanism 6 is reset, the operator starts the cleaning mechanism 6 to clean the inside of the stone mill trough body 2. This achieves the effect of not interfering with sesame processing and output and without the need for manual installation or movement of the cleaning mechanism 6.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
