Detailed Implementation

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0018] First, combine Figures 1-8 This invention describes a horizontal spiral weighing and packaging machine according to an embodiment of the present invention, used for the rapid and accurate packaging of large quantities of materials.

[0019] like Figures 1-8 As shown, a horizontal spiral weighing and packaging machine according to an embodiment of the present invention includes: a machine body assembly 1, a feeding assembly 2, a packaging assembly 3, and a feeding assembly 4; The machine body assembly 1 includes: a feeding cylinder 11 and a frame 12; The feeding cylinder 11 is located at the top of the frame 12, and the unloading assembly 2 is located between the feeding cylinder 11 and the frame 12. The outlet end of the feeding cylinder 11 is connected to the unloading assembly 2. The feeding assembly 2 includes: a feeding box 21, a first screw conveyor, a second screw conveyor, and a feeding cylinder 22; The feeding box 21 is located on the frame 12 and its top is connected to the outlet end of the feeding cylinder 11. The inlet ends of the first screw conveyor and the second screw conveyor are located inside the feeding box 21 and their outlet ends are connected to the inlet end of the feeding cylinder 22. The pitch of the first screw conveyor is greater than that of the second screw conveyor. The packaging component 3 is located at the outlet of the feed cylinder 22 and is used to fix the packaging bag. The feeding component 4 is mounted on the frame 12 and located below the packaging component 3, and is used to transport the packaged materials to the next process.

[0020] This application places the packaging bag on the feeding assembly 4 and fixes the packaging bag by the packaging assembly 3. The opening of the packaging bag is set below the feeding cylinder 22. The material is added into the feeding cylinder 11, and the material in the feeding cylinder 11 enters the feeding box 21. The material is conveyed to the feeding cylinder 22 by the first screw conveyor, so that the material enters the packaging bag. When the weight of the material in the packaging bag is close to the weight of the packaging, the first screw conveyor stops conveying the material, and the material is conveyed into the packaging bag by the second screw conveyor, which ensures accurate packaging of the material and improves the efficiency of material packaging.

[0021] like Figures 1-3 As shown, the packaging component 3 includes: an adjustment mechanism and a clamping mechanism; The adjustment mechanism is located on the frame 12 and is connected to the clamping mechanism. It is used to adjust the height of the clamping mechanism. The clamping mechanism is located at the outlet end of the feed cylinder 22 and is used to fix the opening of the packaging bag.

[0022] The clamping mechanism includes: a clamping cylinder 36, a clamping plate 37, and a clamping cylinder 38; The inlet end of the clamping cylinder 36 is set to correspond to the outlet end of the feeding cylinder 22. The clamping cylinder 36 is funnel-shaped. Clamping cylinders 38 are hinged to both sides of the clamping cylinder 36. Clamping plates 37 are connected to the output ends of the clamping cylinders 38. The clamping plates 37 are hinged to the clamping cylinder 36. Both clamping plates 37 are set to correspond to the outlet end of the clamping cylinder 36. The two clamping plates 37 are used to fix the opening of the packaging bag.

[0023] In this embodiment, the clamping cylinder 38 drives the clamping plate 37 to rotate, separating the clamping plate 37 from the outlet end of the clamping cylinder 36 to both sides, and placing the packaging bag on the outlet end of the clamping cylinder 36. The clamping cylinder 38 drives the clamping plate 37 to rotate, so that the two clamping plates 37 clamp the opening of the packaging bag. The material in the feeding cylinder 22 enters the clamping cylinder 36, and the funnel-shaped clamping cylinder 36 allows the material to enter the packaging bag.

[0024] like Figures 1-3 As shown, the adjustment mechanism includes: a telescopic rod 31, an adjustment handle 32, a reducer 33, an adjustment rod 34, and a connecting arm 35; The telescopic rod 31 is mounted on the frame 12, and the reducer 33 is mounted on the top of the telescopic rod 31. The input end of the reducer 33 is connected to the adjusting handle 32, and the output end of the reducer 33 is connected to the adjusting rod 34. The adjusting rod 34 is located inside the telescopic rod 31 and is threadedly connected to the telescopic rod 31 for adjusting the extension and retraction of the telescopic rod 31. One end of the connecting arm 35 is connected to the top of the telescopic rod 31, and the other end is connected to the clamping mechanism.

[0025] In this embodiment, by manually rotating the adjusting handle 32, the speed is reduced by the reducer 33, causing the adjusting rod 34 to rotate, which controls the telescopic rod 31 to extend and retract, thereby adjusting the height of the clamping mechanism.

[0026] like Figures 6-8 As shown, the feeding assembly 4 includes: a feeding mechanism 41 and a positioning arm 42; The feeding mechanism 41 is located below the feeding cylinder 22. Positioning arms 42 are provided on both sides of the feeding mechanism 41, and the positioning arms 42 are provided on the two sides of the packaging bag.

[0027] In this embodiment, the feeding mechanism 41 includes: a frame assembly, a slack assembly, and a conveyor belt; The frame assembly includes: a mounting frame, a movable plate, a fixed roller, and a movable roller; Both sides of the mounting frame are provided with movable plates. The movable plates are located at the first end of the mounting frame and are slidably disposed on the inner side of the mounting frame. A movable roller is provided between the two movable plates. A fixed roller is provided at the second end of the mounting frame. The conveyor belt is sleeved on the fixed roller and the movable roller. The relaxation assembly includes: a relaxation handle, a relaxation lever, a first link, and a second link; The relaxation lever is rotatably mounted on the mounting frame. One end of the relaxation lever passes through the mounting frame and is connected to the relaxation handle. Both ends of the relaxation lever are fixed with a first connecting rod. The first connecting rod is hinged to the first end of the second connecting rod, and the second end of the second connecting rod is hinged to the movable plate.

[0028] The movable plate has a strip-shaped hole, and the mounting bracket has a limiting rod at the corresponding strip-shaped hole, with a limiting plate at the end of the limiting rod.

[0029] When the belt needs to be disassembled, the loosening handle is turned to rotate the loosening lever, causing the first connecting rod to rotate. The second connecting rod then pulls the movable plate to move, which in turn pulls the movable roller inward, loosening the conveyor belt on the frame assembly. This allows the entire conveyor belt to be pulled out from the side of the mounting frame, enabling quick disassembly of the conveyor belt and improving disassembly efficiency.

[0030] By setting strip holes on the movable plate and inserting a limit rod into the strip holes, the movement range of the movable plate is limited.

[0031] like Figures 4-5 As shown, the first screw conveyor includes: a first housing 61, a first motor 62, a first screw rod 63, and a guide cover 64; The first end of the first housing 61 is located inside the feed box 21 and has an opening corresponding to the outlet end of the feed cylinder 11. The second end of the first housing 61 is connected to the guide cover 64. The guide cover 64 is connected to the feed cylinder 22. A first motor 62 is provided on one side of the guide cover 64. The output end of the first motor 62 extends into the guide cover 64 and is connected to the first screw rod 63. The first screw rod 63 is located inside the first housing 61.

[0032] The first screw conveyor includes: a second housing 71, a second motor 72, and a second screw rod 73; The first end of the second housing 71 is located inside the feed box 21 and has an opening corresponding to the outlet end of the feed cylinder 11. The second end of the second housing 71 is connected to the guide cover 64. The second motor 72 is located on one side of the guide cover 64. The output end of the second motor 72 extends into the guide cover 64 and is connected to the second screw rod 73. The second screw rod 73 is located inside the second housing 71.

[0033] In this embodiment, the first end of the first spiral rod 63 and the second spiral rod 73 are both provided with a concave joint and the second end is provided with a convex joint. The guide cover 64 is provided with a first connecting shaft. The first end of the first connecting shaft passes through the guide cover 64 and is connected to the motor, and the second end is inserted into the concave joint. The first end of the second connecting shaft passes through the housing and is rotatably connected to the housing. The second end of the second connecting shaft is provided with a connecting groove, and the protruding joint is inserted into the connecting groove. Both the concave and convex joints are provided with transmission holes, and the second ends of the first and second connecting shafts are provided with U-shaped openings, which are arranged corresponding to the transmission holes. The transmission rod passes through the U-shaped openings and the transmission holes.

[0034] An end cap is provided on one side of the housing, and the first end of the second connecting shaft extends into the end cap and is rotatably connected to the end cap.

[0035] When disassembling the first or second screw conveyor, the end cover is removed from the housing, and the second connecting shaft is removed from the housing. Since both the second end of the first and second connecting shafts are provided with U-shaped openings, the screw rod can be directly pulled out of the housing. Then, the screw rod is removed from the guide cover 64, which realizes the quick disassembly of the first or second screw conveyor and improves the disassembly efficiency.

[0036] like Figures 1-3 As shown, the machine body component 1 includes: a weighing mechanism 5; The weighing mechanism 5 is located below the feeding assembly 4 and is used to weigh the material in the packaging bag. When the weight of the material conveyed into the packaging bag by the first screw conveyor reaches a certain value, the second screw conveyor conveys the material into the packaging bag.

[0037] The body component 1 also includes: a control screen 15; The control panel 15 is mounted on the frame 12. The control panel 15 is used to adjust the weight of the material inside the packaging bag and the weight of the material when the second screw conveyor is turned on.

[0038] In this embodiment, the weighing mechanism 5 weighs the material in real time. When the weight of the material in the packaging bag is close to the set packaging weight, the first screw conveyor stops conveying the material, and the second screw conveyor is controlled to convey the material. The material is accurately conveyed and packaged by the second screw conveyor.

[0039] The weight of the packaged material and the weight of the material in the package bag when the second screw conveyor starts can be manually changed via the control panel 15.

[0040] like Figures 1-3 As shown, the body assembly 1 also includes: casters 13 and feet 14; The caster wheel 13 and the foot 14 are both located at the bottom of the frame 12, with the foot 14 located on the outer side of the caster wheel 13.

[0041] In this embodiment, casters 13 are provided at the bottom of the frame 12 to facilitate the movement of the packaging machine, and feet 14 are used to fix the packaging machine to prevent it from moving during use.

[0042] Above, refer to Figures 1-8 This invention describes a horizontal screw weighing and packaging machine according to an embodiment of the present invention. The packaging bag is placed on the feeding assembly 4 and fixed by the packaging assembly 3. The bag opening is positioned below the unloading cylinder 22. Material is added into the feeding cylinder 11, and the material in the feeding cylinder 11 enters the unloading box 21. The material is then conveyed to the unloading cylinder 22 by a first screw conveyor, allowing the material to enter the packaging bag. When the weight of the material in the packaging bag approaches the packaging weight, the first screw conveyor stops conveying the material, and a second screw conveyor conveys the material into the packaging bag, ensuring accurate packaging of the material and improving packaging efficiency.
