Description

Technical Field

[0001] This invention relates to the field of bagging machine technology, specifically a sortable potato bagging machine and its usage method. Background Technology

[0002] Potatoes are annual herbaceous plants belonging to the Solanaceae family and the Solanum genus. They are sweet in taste and neutral in nature, and have the effects of invigorating qi, strengthening the spleen, harmonizing the stomach, detoxifying, and reducing swelling. Potato tubers contain a variety of vitamins and inorganic salts, which can prevent scurvy, stimulate hematopoietic function, protect cardiovascular health, and promote overall health. In the food processing industry, potatoes can be processed into various quick-frozen convenience foods and snack foods, such as dehydrated products, fried potato chips, quick-frozen French fries, and puffed foods. At the same time, they can also be further processed into fructose syrup, citric acid, biodegradable plastics, adhesives, reinforcing agents, and various pharmaceutical additives.

[0003] Before food processing, potatoes need to be sorted and bagged according to their size for storage. Existing bagging machines can only bag potatoes and cannot sort them according to the required size. In addition, because the bags are deep, the potatoes that are put in first are far from the bottom of the bag and are prone to bumping and knocking when they fall, which makes the potatoes easy to break during bagging. Summary of the Invention

[0004] To address the problems of inconvenient sorting and easy damage to potatoes when they fall to the bottom of the packaging bag in existing potato bagging machines, this invention provides a sortable potato bagging machine and its usage method to solve the above problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A sortable potato bagging machine and its usage method include a conveyor frame and support legs. Support legs are symmetrically fixed at the bottom of two conveyor frames.

The gears of the several conveyor rollers are connected by a chain. A protective cover is provided on the outside of the chain. The protective cover is fixed to the side wall of the conveyor frame by bolts. The distance between any two adjacent conveyor rollers gradually increases from the feeding end to the unloading end.

[0007] A conveyor belt is provided between the two conveyor frames on the side of the conveyor roller at the feeding end. Both ends of the conveyor belt are connected to belt rollers. The belt rollers are rotatably connected to the conveyor frames through bearings. A servo motor is provided on the outside of the protective cover near the end of the conveyor belt. The output end of the servo motor rotates through the inside of the protective cover. One end of the servo motor extending into the inside of the protective cover is fixed to the conveyor roller. Both the output end of the servo motor and the end of the belt roller extending to the outside of the conveyor frame are fixed with pulleys. The two pulleys are connected by a conveyor belt.

[0008] The bottom of the conveyor roller is provided with several guide components, and a support component is provided below the guide components. A limit component is provided inside the conveyor frame above the connection between the conveyor roller and the conveyor belt.

[0009] Furthermore, the guiding assembly includes a guide sleeve, a detachable guide sleeve is fixed to the bottom of the conveying roller, a support ring is fixed below the bottom of the guide sleeve, a fixing ring is fitted on the top of the support ring, a groove is opened at the bottom of the fixing ring to cooperate with the support ring, an anti-slip rubber sleeve is glued and fixed inside the groove, a connecting plate is symmetrically fixed at the bottom of each bottom support ring, and a side support rod is fixed on the top surface of the connecting plate on the outer side of the support ring, and each side support rod is fixed to the bottom side of the guide sleeve by bolts.

[0010] Furthermore, two adjacent guide sleeves are fitted together, each guide sleeve is configured as a hollow bucket shape with an expanded opening facing the conveyor roller, each fixed ring sleeve has a sliding sleeve fixed on both sides, each sliding sleeve is slidably fitted on the side support rod, each side support rod has a handle fixed on its outer side, and the sum of the lengths of each fixed ring sleeve, sliding sleeve and handle is less than the length of the guide sleeve.

[0011] Furthermore, each guide sleeve is fixed with a fixed side plate on both sides, and a support groove is provided on the inner side of the conveyor frame below the conveyor roller. Each fixed side plate is slidably inserted into the support groove. A fixed through groove is provided inside the conveyor frame at the bottom of each support groove. A threaded hole is provided at the end of each fixed side plate. A bolt that passes through the fixed through groove is threaded into each threaded hole for fixing the guide sleeve and the conveyor frame. The ends of the two support grooves away from the conveyor belt are both set to be open.

[0012] Furthermore, the supporting assembly includes a support plate, a support plate is provided below each guide sleeve, a support plate is provided above each support plate, a support rod is fixed at the corner of the top surface of each support plate, each support rod is slidably inserted into the support plate, a spring is sleeved on the support rod on the bottom surface of each support plate, the upper and lower ends of the spring are respectively fixed to the bottom surface of the support plate and the top surface of the support plate, and a limit washer is fixed to one end of each support rod extending above the support plate.

[0013] Furthermore, each support plate has a shock-absorbing sponge fixed on its top surface, and each support plate has through holes at its four corners that mate with the support rod. The diameter of each limiting gasket is larger than the diameter of the through hole. The length of each support plate and support plate is smaller than the length of the guide sleeve. Each support plate has a limiting post fixed at its center on its top surface. Each limiting post has a pressure sensor installed inside it, and each limiting post has a buffer pad glued to its top surface.

[0014] Furthermore, a base is provided under the support plate, and a sliding groove is provided inside the base. A slider is fixed at the center of the bottom surface of each support plate. Each slider is slidably inserted into the base. A fixing screw is threaded into the support plate on both sides of each slider. A fixing block is fixed at one end of each fixing screw extending to the bottom of the support plate.

[0015] Furthermore, each slider is configured as an inverted T-shape, and support pads are symmetrically fixed on the bottom surface of the support plates on both sides of each slider. Anti-slip pads are glued to the bottom surface of each fixing block. The thickness of each support pad is greater than the sum of the thicknesses of the fixing block and the anti-slip pads. The height of each fixing screw is less than the height of the limiting post.

[0016] Furthermore, the limiting component includes a guide plate. The guide plate is slidably disposed inside the conveyor frame above the connection between the conveyor roller and the conveyor belt. A fixing plate is symmetrically fixed on the side of the guide plate away from the conveyor belt. Fixing screws are threaded into the interior of both fixing plates. Fixing blocks are fixed to the ends of the two fixing screws near the conveyor frame. Anti-slip pads are glued to the side of the fixing blocks facing the conveyor frame. The guide plate is set to be inclined upwards towards the side away from the conveyor roller. A rubber support plate is fixed to the top surface inside the conveyor belt. The top surface of the rubber support plate is in contact with the bottom surface of the upper conveyor belt.

[0017] Furthermore, a method of using a sorting potato bagging machine includes the following steps:

[0018] Step A: Install guide sleeves and adjust support plates and guide plates according to the sorting range requirements;

[0019] Step A1: According to the sorting range of potato size, select the corresponding length and number of guide sleeves. Insert the fixed side plates on both sides of the guide sleeve into the support groove. Then screw bolts into the threaded holes on both sides of the guide sleeve furthest from the conveyor belt. When screwing in, pass the bolts through the fixed through groove and fix them with the threaded holes. The bolts abut against the bottom surface of the conveyor frame to fix the guide sleeve.

[0020] Step A2: After the guide sleeve is installed, pull the support plate to make the support plate and support pad slide on the top surface of the base, and at the same time make the slider slide inside the slide groove. Adjust the support plate to be directly below the guide sleeve. After the adjustment is completed, tighten the fixing screw one to make the fixing pressure block one abut against and fix it on the base, and fix the support plate below the guide sleeve.

[0021] Step A3: Adjust the position of the guide plate according to the sorting quantity and potato volume. When adjusting, turn the two fixing screws on both sides to make the two fixing blocks move away from the conveyor frame. Pull the guide plate to adjust the distance between the guide plate and the top surface of the conveyor belt. After the adjustment is completed, turn the two fixing screws in the opposite direction to drive the two fixing blocks to abut and fix on the conveyor frame.

[0022] Step B: Pour in the potatoes for sorting;

[0023] Step B1: First, place the packaging bag inside the support ring and fold the opening of the packaging bag outwards onto the support ring. Hold the handle and press down on the sliding sleeve to move the fixing ring down onto the packaging bag on the support ring, thus fixing the packaging bag onto the support ring. At this time, the bottom of the packaging bag rests on the support plate.

[0024] Step B2: After the packaging bags are completed, pour the potatoes onto the conveyor belt outside the guide plate. When pouring, the potatoes are supported by the rubber trays inside the conveyor belt to prevent the conveyor belt from deforming and to dampen the potatoes falling onto the conveyor belt.

[0025] Step B3: After pouring, turn on the servo motor to make it run and drive the connected conveyor roller to rotate. The conveyor roller drives the chain to move through the gear, thereby driving all the conveyor rollers to rotate synchronously. At the same time, the conveyor belt and pulley drive the belt roller inside the conveyor belt to rotate, and the belt roller drives the conveyor belt to move.

[0026] Step B4: The conveyor belt transports the potatoes to the top of the conveyor roller. The conveyor roller rotates and drives the potatoes forward. During the forward movement, potatoes smaller than the distance between two conveyor belts fall into the guide sleeve and enter the packaging bag under the guidance of the guide sleeve. When the potatoes fall into the packaging bag, they hit the support plate. After being hit, the support plate compresses the spring to buffer the impact force generated by the potatoes.

[0027] Step C: Replace the packaging bag after bagging is complete;

[0028] Step C1: As the number of potatoes inside the packaging bag increases and the weight increases, the support plate slides down on the support rod under the compression spring until the bottom surface of the support plate abuts against the buffer pad. The gravity sensor inside the limit post detects the signal and issues an alarm.

[0029] Step C2: After receiving the alarm, the staff pulls the fixing ring upward to remove the top of the packaging bag from the support ring, and pulls the packaged bag out from the side of the conveyor frame. The new packaging bag is then quickly placed into the support ring for packaging. At this time, the pressure on the support plate is released, and the support plate is pushed by the spring to abut against the limit pad again.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. In this invention, potatoes passing on the conveyor rollers are sorted by gradually increasing the interval between the conveyor rollers. Smaller potatoes are selected first and bagged, which solves the problem that existing potato bagging machines are inconvenient to sort during use. This allows the bagging machine to distinguish the volume of potatoes during bagging, which is convenient for subsequent production and processing.

[0032] 2. In this invention, a liftable support plate supports the packaging bag. When the number of potatoes in the packaging bag is small and the volume is light, the spring at the bottom pushes the support plate close to the guide sleeve, preventing the potatoes from falling to the bottom of the packaging bag and causing damage. This solves the problem that existing potato bagging machines are prone to damage when potatoes fall to the bottom of the packaging bag. As the number of potatoes inside increases and the weight increases, the support plate compression spring moves downward, ensuring the amount of potatoes collected in the packaging bag.

[0033] 3. In this invention, the adjustable design of the guide sleeve and the support plate allows for the replacement of the sorting section end according to production needs. By adjusting the length of the guide sleeve, potatoes of different size ranges can be sorted, improving the practicality of the bagging machine. Furthermore, the guide sleeve is easy to remove and clean.

[0034] 4. In this invention, the top support ring and fixing ring can open and fix the opening of the packaging bag, which facilitates feeding before the packaging bag is collected and unloading after collection. With the conveyor belt at the feeding port, feeding potatoes is also more convenient, making the bagging machine easier and less labor-intensive to operate. Attached Figure Description

The bottom of each support groove 25 has a fixing through groove 26 inside the conveyor frame 1. Each fixing side plate 27 has a threaded hole 28 at its end. Each threaded hole 28 has a bolt threaded through the fixing through groove 26 for fixing the guide sleeve 8 and the conveyor frame 1. The ends of the two support grooves 25 away from the conveyor belt 5 are both open.

[0051] As a further optimization, the support assembly includes a support plate 12. Each guide sleeve 8 is provided with a support plate 12 below it, and a support plate 13 is provided above each support plate 12. A support rod 14 is fixed at the corner of the top surface of each support plate 12. Each support rod 14 is slidably inserted into the support plate 13. A spring 15 is sleeved on the support rod 14 on the bottom surface of each support plate 13. The upper and lower ends of the spring 15 are respectively fixed to the bottom surface of the support plate 13 and the top surface of the support plate 12. A limit pad 16 is fixed at one end of each support rod 14 that extends above the support plate 13.

[0052] Specifically, each support plate 13 has a shock-absorbing sponge fixed to its top surface, and each support plate 13 has through holes at its four corners that mate with the support rod 14. The diameter of each limiting gasket 16 is larger than the diameter of the through hole. The length of each support plate 12 and support plate 13 is less than the length of the guide sleeve 8. A limiting post 17 is fixed at the center of the top surface of each support plate 12. A pressure sensor is installed inside each limiting post 17.

A cushioning pad 18 is fixed at the center of the bottom surface of each support plate 12. Each slider 21 is slidably inserted into the base 19. Each slider 21 has a fixed screw 23 threadedly connected to the support plate 12 on both sides. Each fixed screw 23 is fixed to a fixed pressure block 24 at one end extending below the support plate 12. Each slider 21 is designed as an inverted T-shape. Each slider 21 has a support pad 22 symmetrically fixed to the bottom surface of the support plate 12 on both sides. Each fixed pressure block 24 has an anti-slip pad glued to the bottom surface. The thickness of each support pad 22 is greater than the sum of the thicknesses of the fixed pressure block 24 and the anti-slip pad. The height of each fixed screw 23 is less than the height of the limiting post 17.

[0053] Working principle: Based on the sorting range of potato sizes, select guide sleeves 8 of corresponding length and number. Insert the fixed side plates 27 on both sides of the guide sleeve 8 into the support groove 25. Then, screw bolts into the threaded holes 28 on both sides of the guide sleeve 8 furthest from the conveyor belt 5. When screwing in, the bolts pass through the fixed through groove 26 and are fixed with the threaded holes 28. The bolts abut against the bottom surface of the conveyor frame 1, thereby fixing the guide sleeve 8. After the guide sleeve 8 is installed, pull the support plate 12, causing the support plate 12 and the support pad 22 to slide on the top surface of the base 19, while simultaneously causing the slider 21 to slide in the groove 20. Slide the internally to adjust the support plate 12 to be directly below the guide sleeve 8. After the adjustment is completed, turn the fixing screw 23 to drive the fixing block 24 to abut and fix it on the base 19, and fix the support plate 12 below the guide sleeve 8. Adjust the position of the guide plate 32 according to the sorting quantity and potato volume. When adjusting, turn the fixing screws 35 on both sides to make the fixing block 34 move away from the conveyor frame 1, pull the guide plate 32, and adjust the distance between the guide plate 32 and the top surface of the conveyor belt 5. After the adjustment is completed, turn the fixing screw 35 in the opposite direction to drive the fixing block 34 to abut and fix it on the conveyor frame 1.

[0054] When sorting potatoes, first place the packaging bag inside the support ring 9, and fold the opening of the packaging bag outwards onto the support ring 9. Hold the handle and press down on the sliding sleeve 31 to move the fixing ring 10 down and onto the packaging bag on the support ring 9, fixing the packaging bag onto the support ring 9. At this time, the bottom of the packaging bag rests on the support plate 13. After the packaging bag is set, pour the potatoes onto the conveyor belt 5 outside the guide plate 32. When pouring, the rubber support plate inside the conveyor belt 5 prevents the conveyor belt 5 from deforming and also dampens the potatoes falling on the conveyor belt 5. After pouring, turn on the servo motor 4 to drive its connected... The conveyor roller 3 rotates, and the conveyor roller 3 drives the chain to move through the gear, thereby driving all the conveyor rollers 3 to rotate synchronously. At the same time, the conveyor belt 6 and the pulley drive the belt roller inside the conveyor belt 5 to rotate. The belt roller drives the conveyor belt 5 to move. The conveyor belt 5 conveys the potatoes to the top of the conveyor roller 3. The rotation of the conveyor roller 3 drives the potatoes forward. During the forward movement, potatoes smaller than the distance between two conveyor belts 5 fall into the guide sleeve 8 and enter the packaging bag under the guidance of the guide sleeve 8. When the potatoes fall into the packaging bag, they hit the support plate 13. After the support plate 13 is hit, it compresses the spring 15 to buffer the impact force of the potatoes.

[0055] After bagging is completed, the packaging bag is replaced. As the number of potatoes inside the packaging bag increases and the weight increases, the support plate 13 slides down on the support rod 14 under the compression spring 15 until the bottom surface of the support plate 13 abuts against the buffer pad 18. The gravity sensor inside the limit post 17 detects the signal and issues an alarm. After receiving the alarm, the staff pulls the fixing ring 10 upward to remove the top of the packaging bag from the support ring 9 and pulls the bagged packaging bag out from the side of the conveyor 1. The new packaging bag is quickly placed into the support ring 9 for fitting. At this time, the squeezing pressure on the support plate 13 is released, and the support plate 13 abuts against the limit pad 16 again under the push of the spring 15.

10. A method of using the sortable potato bagging machine according to any one of claims 1-9, characterized in that: The method of use includes the following steps: Step (A): Install guide sleeve (8) according to the sorting range requirements; adjust support plate (12) and guide plate (32); Step (A1): Select the guide sleeve (8) of the corresponding length and number according to the sorting range of potato size. Insert the fixed side plates (27) on both sides of the guide sleeve (8) into the support groove (25). Then screw the bolts into the threaded holes (28) on both sides of the guide sleeve (8) that are farthest from the conveyor belt (5). When screwing in, pass the bolts through the fixed through groove (26) and fix them with the threaded holes (28). The bolts abut against the bottom surface of the conveyor frame (1) to fix the guide sleeve (8). After step (A2) and guide sleeve (8) are installed, pull support plate (12) to drive support plate (12) and support pad (22) to slide on the top surface of base (19), and at the same time drive slider (21) to slide inside slide groove (20) to adjust support plate (12) to be directly below guide sleeve (8). After adjustment, turn the fixing screw (23) to drive fixing pressure block (24) to abut and fix on base (19) to fix support plate (12) below guide sleeve (8). Step (A3): Adjust the position of the guide plate (32) according to the sorting quantity and potato volume. When adjusting, turn the two fixing screws (35) on both sides so that the two fixing blocks (34) are away from the conveyor frame (1). Pull the guide plate (32) to adjust the distance between the guide plate (32) and the top surface of the conveyor belt (5). After the adjustment is completed, turn the two fixing screws (35) in the opposite direction to drive the two fixing blocks (34) to abut and fix on the conveyor frame (1). Step (B): Pour in the potatoes for sorting; Step (B1): First, place the packaging bag inside the support ring (9), and turn the opening of the packaging bag outward and put it on the support ring (9). Hold the handle and press down the sliding sleeve (31) to drive the fixing ring sleeve (10) to move down and put it on the packaging bag on the support ring (9), and fix the packaging bag on the support ring (9). At this time, the bottom of the packaging bag falls on the support plate (13). Step (B2): After the packaging bag is completed, pour the potatoes onto the conveyor belt (5) outside the guide plate (32). When pouring, the potatoes falling onto the conveyor belt (5) are damped by the rubber support plate inside the conveyor belt (5) to prevent the conveyor belt (5) from deforming. Step (B3): After pouring, turn on the servo motor (4) so ​​that the servo motor (4) runs and drives the connected conveyor roller (3) to rotate. The conveyor roller (3) drives the chain to move through the gear, thereby driving all the conveyor rollers (3) to rotate synchronously. At the same time, the belt roller inside the conveyor belt (5) is driven to rotate through the conveyor belt (6) and the pulley. The belt roller drives the conveyor belt (5) to move. Step (B4): The conveyor belt (5) transports the potatoes to the top of the conveyor roller (3). The conveyor roller (3) rotates and drives the potatoes forward. During the forward movement, potatoes smaller than the distance between the two conveyor belts (5) fall into the guide sleeve (8) and enter the packaging bag under the guidance of the guide sleeve (8). When the potatoes fall into the packaging bag, they hit the support plate (13). After the support plate (13) is hit, the spring (15) is compressed to buffer the impact force generated by the potatoes. Step (C): Replace the packaging bag after bagging is complete; Step (C1): As the number of potatoes inside the packaging bag increases and the weight increases, the support plate (13) slides down on the support rod (14) under the compression spring (15) until the bottom surface of the support plate (13) abuts against the buffer pad (18). The gravity sensor inside the limit post (17) detects the signal and issues an alarm. Step (C2): After receiving the alarm, the staff pulls the fixing ring (10) upward to remove the top of the packaging bag from the support ring (9), and pulls the packaged bag out from the side of the conveyor (1) after it is filled. The new packaging bag is quickly placed into the support ring (9) for packaging. At this time, the squeezing force on the support plate (13) is released, and the support plate (13) is pushed by the spring (15) and abuts against the limiting pad (16) again.
