Detailed Implementation

[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0016] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please refer to Figures 1 to 8 This utility model provides an automatic cup counting and packaging machine, including a feeding mechanism 1, a counting mechanism 2, a conveying mechanism 3, and a packaging host 4; the feeding mechanism 1 and the conveying mechanism 3 are arranged opposite to each other with a gap between them; the counting mechanism 2 is mounted on the conveying mechanism 3 and is arranged opposite to the feeding mechanism 1; the packaging host 4 is arranged opposite to the discharge end of the conveying mechanism 3 and is used to package cups 5; The counting mechanism 2 includes an adjustment component 21, a first counting screw 22, a second counting screw 23, a drive component 24, an air blowing component 25, a support plate 26, and a protective cover 27. The adjustment component 21 is connected to the conveying mechanism 3. The first counting screw 22 and the second counting screw 23 are respectively disposed on the adjustment component 21. The adjustment component 21 is used to drive the first counting screw 22 and the second counting screw 23 to move closer or further apart from each other. The drive component 24 is disposed on the conveying mechanism 3 and is drivenly connected to the first counting screw 22 and the second counting screw 23 respectively. The air blowing component 25 is used to blow the cup 5 toward the conveying mechanism 3. The support plate 26 is disposed below the first counting screw 22 and the second counting screw 23. The protective cover 27 is connected to the adjustment component 21.

[0019] In the embodiments of this utility model, the feeding mechanism 1, the counting mechanism 2, the conveying mechanism 3, and the packaging host 4 are connected in sequence to form a continuous process of "feeding → counting → conveying → packaging", which eliminates the need for manual transfer or segmented operation, reduces process interruptions, and improves overall production efficiency.

[0020] Specifically, the feeding mechanism 1 can be a belt conveyor 2411 to receive stacks of cups 5. The counting mechanism 2 is directly integrated into the conveying mechanism 3, eliminating the need for an additional independent mounting base and effectively saving equipment floor space. Since the counting mechanism 2 requires a drive assembly 24 to drive the first counting screw 22 and the second counting screw 23, a gap is provided between the feeding mechanism 1 and the conveying mechanism 3. Part of the drive assembly 24 can extend to the side from the gap to transmit power. The split structure allows for arbitrary selection of the size of the feeding mechanism 1, making it well-suited for existing equipment. The adjustment assembly 21 can move the first and second counting screws 23 closer together or further apart, flexibly adapting to cups 5 of different diameters and mouth sizes. The entire counting mechanism 2 does not need to be replaced; simply adjusting the screw spacing can meet the counting requirements of multiple product specifications. The first counting screw 22 and the second counting screw 23 work in conjunction with the drive assembly 24 to ensure stable separation and transport of the cups 5, preventing issues such as missed or excessive counting caused by cups 5 stacking or jamming. The air blowing assembly 25 blows air towards the feed end of the conveyor mechanism 3, separating the counted cups 5 a certain distance to better coordinate with the conveyor mechanism 3. The conveyor mechanism 3 can be a scraper or chain conveyor, allowing the blown cups 5 to quickly enter the conveyor mechanism 3. The conveyor mechanism 3 directly connects to the packaging host 4, allowing the counted cups 5 to quickly enter the packaging stage, shortening the transport path, reducing secondary displacement of the cups 5 during transport, and further improving packaging efficiency. The pallet 26 is located below the twin screws, supporting the cups 5 during the counting process, especially lightweight plastic cups and thin wallpaper cups, preventing them from tipping over, falling, or shifting in position. The protective cover 27 is installed on the adjustment component 21 to prevent operators from accidentally touching the operating screw and drive components, avoid the risk of mechanical injury, and improve operational safety. On the other hand, it can block dust and debris from entering the counting mechanism 2, reduce the wear of screw, bearing and other components, extend the service life of the equipment, and prevent debris from contaminating the cup 5, thus ensuring the cleanliness of the product.

[0021] The working process of this utility model is as follows: According to the specifications of the cups 5 to be packaged, the first counting screw 22 and the second counting screw 23 are driven to move closer or further apart by the adjusting component 21 to adjust the spacing to suit the cups 5. The feeding mechanism 1 transports the cups 5 in batches to the docking gap with the conveying mechanism 3. The driving component 24 is started, which drives the first counting screw 22 and the second counting screw 23 to operate synchronously. The two screws work together to separate individual cups 5 and transport them one by one. The pallet 26 supports the cups 5 below to prevent them from tipping over or shifting. The air blowing component 25 blows air toward the cups 5 that have been counted, blowing the cups 5 a certain distance before they enter the conveying mechanism 3. The cups 5 move toward the discharge end with the conveying mechanism 3. After arriving at the docking position of the packaging host 4, the packaging host 4 automatically packages the quantitative cups 5, completing the entire counting and packaging process.

[0022] Preferably, the first counting screw 22 and the second counting screw 23 have the same structure; the first counting screw 22 includes a screw body 221 and a screw shaft 222, the screw body 221 is sleeved on the screw shaft 222, and the surface of the screw body 221 is provided with helical teeth 223. In this embodiment, the counting screws with the same structure, driven by the drive assembly 24, have completely consistent rotation speed and helical tooth 223 advance rhythm, which can form a symmetrical and synchronous conveying force, ensuring that the cups 5 are smoothly and evenly separated and conveyed between the two screws, avoiding uneven force and inconsistent conveying speed caused by differences in screw structure, and effectively preventing the cups 5 from jamming, stacking, or being missed. The spiral teeth 223 on the surface of the screw body 221 can effectively mesh with the rim of the cup 5. When rotating, the propulsive force of the spiral teeth 223 drives the cups 5 to move forward one by one. At the same time, the pitch of the spiral teeth 223 separates two adjacent cups 5, thereby achieving the effect of conveying cups 5 one by one and accurate counting, avoiding counting errors caused by multiple cups 5 passing through the counting station at the same time.

[0023] Furthermore, by calculating the transmission and controlling the length of the spiral teeth 223, the screw body 221 can rotate one or more times for each specific number of cups 5 packaged by the packaging host 4, thereby better meeting packaging requirements.

[0024] Preferably, the distance between two adjacent tips on the spiral tooth 223 is equal to the distance between the rims of two adjacent cups 5. In this embodiment, the tip spacing perfectly matches the rim spacing, so that each tip of the spiral tooth 223 corresponds exactly to the rim position of a cup 5. When the screw rotates, each tip only drives one cup 5 forward, structurally preventing one tip from driving multiple cups 5 or cups 5 from leaking into the tip gap. This ensures that the number of cups 5 conveyed during counting strictly corresponds to the number of screw rotations and the number of tips, avoiding problems of over-counting or under-counting.

[0025] Preferably, the adjusting assembly 21 includes a pair of mounting plates 211, a pair of sliding support shafts 212, a first upright plate 213, a second upright plate 214, a positive and negative threaded rod 215, and a handle 216; the pair of mounting plates 211 are symmetrically arranged on both sides of the conveying mechanism 3, and the pair of sliding support shafts 212 are arranged parallel to each other between the pair of mounting plates 211; the first upright plate 213 and the second upright plate 214 are slidably mounted on the pair of sliding support shafts 212; the positive and negative threaded rod 215 is rotatably mounted on the pair of sliding support shafts 212. The first upright plate 213 and the second upright plate 214 are respectively located on the positive and negative threads of the positive and negative threaded rod 215, which is used to drive the first upright plate 213 and the second upright plate 214 to move closer or further apart; the handle 216 is connected to the end of the positive and negative threaded rod 215; the first counting screw 22 is rotatably connected to the first upright plate 213, and the second counting screw 23 is rotatably connected to the second upright plate 214.

[0026] In this embodiment, when the lead screw 215 rotates, the first vertical plate 213 and the second vertical plate 214 respectively engage with the lead screw's forward and reverse thread sections, moving synchronously towards the center or away from both sides. This ensures that the spacing adjustment of the first and second counting screws 23 is always symmetrical and synchronous, avoiding the problem of non-parallelism of the twin screw axes 222 caused by unilateral screw offset, and ensuring uniform force on the cup 5 during counting. Simultaneously, the synchronous adjustment method requires only one operation to complete the spacing adjustment, adapting to the rapid changeover needs of multiple cup sizes 5. The handle 216 is directly connected to the end of the lead screw 215, eliminating the need for an additional motor or electrical control system. Adjustment can be completed by manually rotating the handle 216, resulting in a low operating threshold and reducing equipment manufacturing and maintenance costs.

[0027] Furthermore, the accuracy of operation can be further improved by setting up a digital position display.

[0028] Preferably, the first upright plate 213 and the second upright plate 214 have the same structure. The first upright plate 213 includes an upright plate 213a, an upright plate 213b, a bearing seat 213c, and a bearing seat 213d. The upright plate 213a is threadedly connected to the positive and negative threaded screws 215. The upright plate 213b is disposed on the upright plate 213a. The bearing seat 213c and the bearing seat 213d are respectively disposed on both sides of the upright plate 213b. One end of the first counting screw 22 is rotatably connected to the bearing seat 213c, and the other end is rotatably connected to the bearing seat 213d. In this embodiment, the upright plates with the same structure ensure that the installation height and horizontal position of the first and second counting screws 23 are completely consistent, further enhancing the synchronization of the twin-screw drive. Bearing housing 213c and bearing housing 213d support the two ends of the first-point screw 22 respectively, forming a support structure with fixed ends. Compared with single-sided support or single-point support, this can effectively limit the radial wobble and axial movement of the screw during rotation, ensuring the coaxiality and stability of the screw operation. At the same time, it disperses the force generated by the screw rotation, reduces the wear of the bearings and screw, extends the service life of the screw and bearings, and reduces the probability of equipment failure.

[0029] Preferably, the air blowing assembly 25 includes a first air blowing unit and a second air blowing unit. The first air blowing unit is disposed on the first upright plate 213, and the second air blowing unit is disposed on the second upright plate 214. The first air blowing unit and the second air blowing unit have the same structure. The first air blowing unit includes a fixing block 251 and an air pipe 252. The fixing block 251 is connected to the side of the first upright plate 213, and the air pipe 252 is disposed on the fixing block 251. One end of the air pipe 252 is connected to an air pump, and the other end is disposed towards the feed end of the conveying mechanism 3. In this embodiment, the first air blowing unit is disposed on the first upright plate 213, and the second air blowing unit is disposed on the second upright plate 214, forming a symmetrical air blowing layout. Air is blown synchronously from both sides of the cup 5, which can more efficiently drive the cup 5 forward and reduce the probability of positional deviation during the forward movement of the cup 5. The blowing unit moves synchronously with the upright plate, and the spacing of the upright plate is adjusted by the positive and negative threaded rods 215 to accommodate the width of cups 5 of different sizes. It always keeps the blowing direction facing both sides of the cup 5, ensuring that the blowing effect remains stable no matter how the size of the cup 5 is adjusted.

[0030] Preferably, the device further includes a cup-pressing assembly, which includes a pressing strip and a pressing block 28. The pressing block 28 is adjustablely mounted on the sliding support shaft 212, and the pressing strip is connected to the pressing block 28. The pressing strip is used to press down on the cup 5. In this embodiment, the pressing block 28 is mounted on the sliding support shaft 212, and its position can be adjusted along the axial direction of the sliding support shaft 212. The pressing strip is made of an elastic material, which can press down on the top of the cup 5 without damaging the cup 5. Specifically, the pressing strip acts directly on the top or rim of the cup 5, which can effectively suppress the bouncing or displacement of the cup 5 during the separation and conveying process of the twin screw, especially for lightweight plastic cups, tall paper cups and other easily shaken products, ensuring that the cup 5 always maintains a stable posture when passing through the counting mechanism 2, improving counting accuracy and conveying continuity.

[0031] Preferably, the drive assembly 24 includes a drive shaft 241, a drive bevel gear 242, a driven bevel gear 243, a driven shaft 244, a first sprocket 245, a second sprocket 246, a third sprocket 247, a fourth sprocket 248, a fifth sprocket 249, a sixth sprocket 2410, a belt 2411, and a tensioning part 2412; the drive shaft 241 and the driven shaft 244 are rotatably mounted on the conveying mechanism 3, the drive bevel gear 242 is located at the end of the drive shaft 241, and the two ends of the driven shaft 244 are respectively connected to the driven bevel gear 243 and the first sprocket 2410. 5. The driving bevel gear 242 meshes with the driven bevel gear 243; the second sprocket 246 and the third sprocket 247 are respectively disposed on the adjusting assembly 21, the fourth sprocket 248 is disposed on the second counting screw 23, the fifth sprocket 249 is disposed on the tensioning part 2412, and the sixth sprocket 2410 is disposed on the first counting screw 22; the belt 2411 is connected to the first sprocket 245, the second sprocket 246, the third sprocket 247, the fourth sprocket 248, the fifth sprocket 249, and the sixth sprocket 2410 respectively.

[0032] In this embodiment, an external power drives the drive shaft 241 to rotate, and the drive bevel gear 242 at the end of the drive shaft 241 rotates accordingly. Through meshing, it drives the driven bevel gear 243 to rotate, thereby realizing power reversal and driving the driven shaft 244 to rotate synchronously. When the driven shaft 244 rotates, it drives the first sprocket 245 on it to rotate. The first sprocket 245 transmits power sequentially to the second sprocket 246, the third sprocket 247 on the adjusting assembly 21, and the fifth sprocket 249 on the tensioning part 2412 via the belt 2411. The fifth sprocket 249 adjusts its position through the tensioning part 2412 to keep the belt 2411 taut, preventing the belt 2411 from slipping and ensuring the continuity and stability of power transmission. The belt 2411 finally transmits power to the fourth sprocket 248 on the second counting screw 23 and the sixth sprocket 2410 on the first counting screw 22, driving the first and second counting screws 23 to rotate synchronously, thereby realizing the counting and conveying action of the cup 5.

[0033] Preferably, the tensioning part 2412 includes a tensioning plate 2412a, a fixed shaft 2412b, a pad 2412c, and an end cap 2412d; one end of the tensioning plate 2412a is rotatably connected to the fifth sprocket 249, and the other end is connected to the fixed shaft 2412b; the pad 2412c is disposed on the fixed shaft 2412b; the other end of the fixed shaft 2412b is connected to the end cap 2412d conveying mechanism 3; the end cap 2412d is connected to the adjusting component 21 and the conveying mechanism 3 respectively.

[0034] In this embodiment, one end of the tension plate 2412a is rotatably connected to the fifth sprocket 249, and the other end is connected to the fixed shaft 2412b. By adjusting the swing angle of the tension plate 2412a around the fixed shaft 2412b, the spatial position of the fifth sprocket 249 can be changed, thereby flexibly adjusting the tension of the belt 2411. When the belt 2411 is slack, swinging the tension plate 2412a causes the fifth sprocket 249 to move outward, which tightens the belt 2411. When the belt 2411 is too tight, the opposite adjustment can be made. There is no need to disassemble the belt 2411 or replace parts, making the operation convenient and the adjustment precision high, which can quickly adapt to the belt 2411 tension requirements under different working conditions.

[0035] Furthermore, for ease of adjustment, the pad 2412c is designed with a hexagonal cross-section and is fixedly connected to the fixed shaft 2412b. When adjusting the position of the tension plate 2412a, a wrench can be applied to the pad 2412c, which will then drive the fixed shaft 2412b to rotate. After rotating to the correct position, the fixed shaft 2412b is locked onto the end cap 2412d. The end cap 2412d is connected to the bottom of the adjusting assembly 21 and the front end of the conveying mechanism 3, which helps to improve stability.

[0036] Preferably, the conveying mechanism 3 has a drive shaft 31 at one end near the packaging host 4, and the drive shaft 31 is connected to the packaging power output shaft of the packaging host 4. A first drive sprocket 32 ​​is mounted on the drive shaft 31, and a second drive sprocket 33 is mounted on the drive shaft 241. The first drive sprocket 32 ​​and the second drive sprocket 33 are connected by a chain. With this structural arrangement, the drive shaft 31 of the conveying mechanism 3 is connected to the packaging power output shaft of the packaging host 4, and the drive shaft 31 drives the drive shaft 241 of the counting mechanism 2 via a chain-sprocket connection, achieving power sharing. This eliminates the need for separate motors, reducers, and other power units for the conveying mechanism 3 and the counting mechanism 2, significantly reducing the equipment's power system procurement costs and installation space requirements, while also lowering the overall energy consumption and subsequent power system maintenance costs. In addition, the power of the conveying mechanism 3 comes directly from the power output shaft of the packaging host 4. The conveying speed is strictly synchronized with the packaging speed of the packaging host 4. When the packaging host 4 speeds up / down, the conveying mechanism 3 adjusts synchronously, which can effectively prevent the cups 5 at the front end of the packaging from accumulating due to excessively fast conveying, or the packaging host 4 from stopping due to insufficient material conveying due to excessively slow conveying, thus ensuring the consistency of the rhythm of the whole process and improving the overall production efficiency.

[0037] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a feeding mechanism to deliver cups to a counting mechanism, and utilizes the rotation of a first and second counting screw to separate and forward transport the stacked cups, allowing for control over the number of cups. A conveying mechanism and a packaging host are then used to package single or multiple cups. Furthermore, the adjusting component can flexibly adjust the distance between the first and second counting screws to accommodate cups of different diameters. This invention achieves integrated operation from feeding and counting of stacked cups to packaging, reducing intermediate steps and effectively improving the efficiency of cup packaging production.

Many modifications and variations will be apparent to those skilled in the art.
