Description

Technical Field

[0001] The utility model relates to the technical field of bulk food transportation, in particular to a bulk food sales and transportation unloading anti-fall device. Background Art

[0002] Bulk food refers to food that is not pre-packaged and requires weighing for sale. This includes both unpackaged and non-packaged food, also known as "naked" food, which is sold without packaging. Traditional transport machines unload food directly and roughly, causing it to fall, damage its shape, and result in defective food, which affects sales. To prevent food damage, manual unloading is required, which is slow, labor-intensive, and time-consuming, increasing production costs and inefficiency.

[0003] A Chinese patent with publication number CN215043973U was searched and disclosed, which discloses a device for preventing bulk food from falling during transportation and unloading.

[0004] The utility model includes a support frame, a conveyor belt is fixed on the support frame, and a first fixed plate is fixed on the conveyor belt; the utility model adjusts the height of the lifting rod through a lifting mechanism, and places the rotating rod in a limit groove close to one side of the fixed rod so that the end of the slider contacts the inner wall of the lifting rod. When the slider contacts the inner wall of the lifting rod, the slider squeezes the spring and enters the fixed block. When the slider is in the third groove, the spring pushes the slider to contact the inner wall of the third groove, and then moves the pressure rod from top to bottom to move the lifting rod, and then inserts the rectangular insertion rod into the third slot. The rectangular insertion rod passes through the third groove on the lifting rod to fix the position of the lifting rod, and the item is placed between the two first fixed plates. The item moves to the slide plate through the baffle and falls into the collection box to reduce the height and ensure the safety of the item.

[0005] However, this patent still has the following problems: the device uses the design of the slide to make the bulk food fall onto the surface of the slide first, and then fall into the collection box through the inclined design of the slide. However, with only the inclined design of the slide, it is easy for the bulk food to stay on the surface of the slide due to friction, which makes it easy for the bulk food to accumulate and collide with each other on the surface of the slide, which increases the probability of the bulk food falling and affects the normal collection of the collection box. Utility Model Content

[0006] The purpose of the utility model is to provide a device for preventing bulk food from falling when being sold, transported or unloaded, which automatically transports the bulk food by setting a conveyor belt to prevent the bulk food from staying on the surface of the conveyor belt and being piled up and falling.

[0017] The utility model is provided with a buffer mechanism, and rotating the hand wheel can drive the worm to rotate, so that the worm can drive the rotating shaft to rotate together by meshing with the worm wheel, which makes the connecting plate drive the rotating table to rotate together, so that the inclination angle of the conveyor belt can be adjusted, and the conveyor belt can be more easily aligned with the material receiving mechanism. When the conveyor transports bulk food to the top of the conveyor belt, the side baffle can block the bulk food to prevent it from detaching from the conveyor belt surface during the falling process. When the bulk food falls on the conveyor belt surface, the rubber pad can be compressed and deformed, thereby buffering the impact force exerted on the conveyor belt, so that the impact effect exerted on the bulk food can also be reduced, thereby achieving buffering protection for the bulk food. After that, the reduction motor is started, and the transmission roller drives the conveyor belt to move, so that the bulk food on the surface of the conveyor belt can be conveyed to the inside of the material receiving mechanism, thereby completing the transmission operation of the bulk food.

[0025] See also Figures 1-6 A bulk food sales and transportation unloading anti-fall device includes a conveyor 1, a buffer mechanism 2 and a material receiving mechanism 3 are provided on one side of the conveyor 1;

[0026] The buffer mechanism 2 includes a support platform 201, a lifting cylinder 202 is fixed on the surface of the support platform 201, a movable platform 203 is fixed at one end of the lifting cylinder 202, a U-shaped plate 204 is fixed on the top of the movable platform 203, a worm 206 is rotatably connected to the surface of the U-shaped plate 204, two first side plates 205 are fixed on the top of the U-shaped plate 204, and the first side plates 205 on both sides are rotatably connected to the opposite surfaces of the rotating shaft 207, a connecting plate 208 is fixed on the surface of the rotating shaft 207, a rotating platform 209 is fixed on the top of the connecting plate 208, and the rotating platform 209 is slidably connected to the surface of the first side plate 205. A rubber pad 210 is provided with a second side plate 211 fixed on the top of the rubber pad 210. Two transmission rollers 212 are connected to the opposite surfaces of the second side plates 211 on both sides for rotation. A reduction motor 217 is fixed to the surface of the front second side plate 211. The output shaft of the reduction motor 217 passes through the second side plate 211 and is fixedly connected to the surface of the transmission roller 212 at one end. Conveyor belts 213 are installed on the surfaces of the transmission rollers 212 on both sides. A side baffle 214 is fixed to the top of the second side plate 211. A worm gear 218 is fixed to the surface of the rotating shaft 207. The worm gear 218 is meshed with the worm 206. One end of the worm 206 passes through the U-shaped plate 204 and is fixed with a handwheel.

[0027] The rotating handwheel can drive the worm 206 to rotate, so that the worm 206 can drive the rotating shaft 207 to rotate together by meshing with the worm gear 218, which makes the connecting plate 208 drive the rotating table 209 to rotate together, so that the inclination angle of the conveyor belt 213 can be adjusted, so that the conveyor belt 213 can be more easily aligned with the material receiving mechanism 3. When the conveyor 1 conveys bulk food to the top of the conveyor belt 213, the side baffle 214 can block the bulk food to prevent it from falling off the surface of the conveyor belt 213 during the falling process. When the bulk food falls on the surface of the conveyor belt 213, the rubber pad 210 can be compressed and deformed, thereby buffering the impact force on the conveyor belt 213, so that the impact effect on the bulk food can also be reduced, thereby achieving buffering protection for the bulk food. After that, the reduction motor 217 is started, so that the transmission roller 212 drives the conveyor belt 213 to move, so that the bulk food on the surface of the conveyor belt 213 can be conveyed to the inside of the material receiving mechanism 3, completing the transmission operation of the bulk food.

[0028] Furthermore, support plates 215 are fixed to the opposite surfaces of the second side plates 211 on both sides, and the top surface of the support plates 215 is slidably connected to the inner surface of the conveyor belt 213;

[0029] The support plate 215 can support the surface of the conveyor belt 213 to prevent the surface of the conveyor belt 213 from sinking downward when bulk food falls onto the surface of the conveyor belt 213 .

[0030] Furthermore, four guide plates 216 are fixed to the bottom of the movable platform 203, and four slide grooves are provided on the top of the support platform 201 to fit the guide plates 216. The guide plates 216 are slidably connected to the surface of the slide grooves.

[0031] The guide plate 216 can slide in the slide groove on the surface of the support platform 201, so that the movable platform 203 can obtain a linear guiding effect, thereby improving the stability of the guide plate 216 when moving.

[0032] Furthermore, the material receiving mechanism 3 includes a mounting platform 301, which is located on the right side of the support platform 201. A rotating cylinder 302 is fixed on the top of the mounting platform 301, a rotating plate 303 is fixed on the surface of the rotating cylinder 302, two weighing scales 304 are fixed on the top of the rotating plate 303, a storage shell 305 is fixed on the surface of the weighing scale 304, a material receiving shell 306 is slidably connected to the surface of the storage shell 305, and the top of the material receiving shell 306 is located below the rotating platform 209;

[0033] The bulk food transported by the conveyor belt 213 can fall into the receiving shell 306, and the weighing scale 304 can measure the weight of the receiving shell 306. The operator can judge whether the receiving shell 306 is loaded with the required weight by observing the surface data of the weighing scale 304. After the loading requirement is met, the rotating cylinder 302 can be started to rotate the rotating plate 303 180 degrees to swap the positions of the receiving shells 306 on both sides, so that the receiving shell 306 that has not received the material can receive the bulk food, and the receiving shell 306 on the other side can be taken out from the surface of the storage shell 305 and transported again.

[0034] Furthermore, a plurality of springs 307 are fixed on both sides of the inner wall of the storage shell 305, a clamping plate 308 is fixed on the surface of the spring 307, and an inclined surface is provided on the top of the clamping plate 308;

[0035] When the material receiving shell 306 is located inside the storage shell 305, the two side surfaces of the material receiving shell 306 can contact the two side surfaces of the clamping plate 308, and the spring 307 will be in a compressed state, so that the material receiving shell 306 can obtain a clamping effect, thereby preventing the material receiving shell 306 from moving during the material receiving process. At the same time, the design of the inclined surface also enables the material receiving shell 306 to be directly placed downward into the storage shell 305. The cooperation between the bottom of the material receiving shell 306 and the inclined surface can make the clamping plate 308 move by itself.

[0036] Furthermore, a plurality of guide rods 309 are fixed on the surface of the clamping plate 308. The guide rods 309 slide through the storage shell 305. A pull plate 310 is fixed on the surface of the storage shell 305.

[0037] The guide rod 309 helps to maintain the stability of the splint 308 when it moves, so that the guide rod 309 can only move in a straight line. Together with the pull plate 310, it allows the user to move the splint 308 more conveniently. At the same time, it also limits the maximum movement range of the splint 308, ensuring that the bottom of the material receiving shell 306 can contact the inclined surface at the top of the splint 308 when it moves downward.

[0038] Furthermore, a slide rail 311 is fixed on the top of the mounting platform 301, a slider 312 is slidably connected to the surface of the slide rail 311, and the top of the slider 312 is fixedly connected to the bottom of the rotating plate 303;

[0039] The slider 312 slides along the surface of the slide rail 311 to help maintain the center position of the rotating plate 303, ensure that the rotating plate 303 rotates more smoothly and accurately, improve the rotation accuracy, and enhance the support effect of the rotating plate 303.

[0040] Furthermore, a plurality of partition plates 4 are fixed to the surface of the conveyor belt 1, and the top position of the conveyor belt 213 is lower than the bottom position of the conveyor belt 1;

[0041] The design of multiple partitions 4 makes it easier for the bulk food to be manually separated and placed, so that the bulk food can be more evenly distributed on the surface of the conveyor belt 1. The design of the position of the conveyor 1 and the conveyor belt 213 ensures that the bulk food transported on the surface of the conveyor 1 can fall normally onto the surface of the conveyor belt 213, and also avoids collision between the partitions 4 and the surface of the conveyor belt 213.

[0042] Working principle: By rotating the hand wheel, the inclination angle of the conveyor belt 213 can be adjusted through the cooperation of the worm 206 and the worm gear 218, so that the conveyor belt 213 can be more easily aligned with the receiving shell 306. When the conveyor 1 conveys bulk food to the surface of the conveyor belt 213, the rubber pad 210 can be compressed and deformed, thereby buffering the impact force on the conveyor belt 213 and the bulk food, and realizing buffering protection for the bulk food. After that, the reduction motor 217 is started, so that the bulk food on the surface of the conveyor belt 213 can be conveyed to the inside of the receiving shell 306, and the conveyor belt 213 is completely loaded. In order to complete the transmission operation of bulk food, the weighing scale 304 can measure the weight of the receiving shell 306. The operator can judge whether the inside of the receiving shell 306 is loaded with the required weight by observing the surface data of the weighing scale 304. After the loading requirement is met, the rotating cylinder 302 can be started to rotate the rotating plate 303 180 degrees to swap the positions of the receiving shells 306 on both sides, so that the receiving shell 306 that has not received the material can receive the bulk food, and the receiving shell 306 on the other side can be taken out from the surface of the storage shell 305 and transported again.

[0043] The above are only preferred embodiments of the present invention and are 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.
