Description

Technical Field

[0001] This utility model relates to the field of chopsticks processing, and in particular to a disposable chopsticks bagging machine. Background Technology

[0002] In the field of automated packaging for disposable tableware, disposable chopsticks, as common catering supplies, directly impact the overall efficiency of the production line due to their packaging efficiency and ease of operation. Currently, widely used disposable chopsticks bagging machines typically include core components such as a feeding mechanism, a bag-opening mechanism, and a sealing mechanism. The bag-opening mechanism is used to open and secure the bag opening, allowing chopsticks to be easily inserted into the bag to complete the bagging process.

[0003] However, existing disposable chopsticks bagging machines still have many shortcomings in practical applications. First, the bag-supporting mechanism is generally located at a high position on the equipment, requiring operators to frequently raise their arms during manual bagging operations. Prolonged operation can easily lead to fatigue, affecting work efficiency and ergonomics. Second, during the bag-supporting process, operators must manually fully open the soft and easily deformable plastic bag opening to its maximum extent and accurately align it with the elastic support plates on both sides of the bag-supporting mechanism. This process is not only cumbersome but also requires a high level of skill. Slight carelessness can cause the bag opening to slip off or not be fully secured, leading to subsequent bagging failures, material jams, or even equipment shutdowns. When the equipment jams, workers need to stand on A-frame ladders to work, increasing the risk of accidents.

[0004] Therefore, there is an urgent need to develop a disposable chopsticks bagging machine that optimizes and improves the bag-supporting structure, reduces the difficulty of manual bagging, and increases bagging efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a disposable chopsticks bagging machine that optimizes and improves the bag support structure, reduces the difficulty of manual bagging, and improves bagging efficiency.

[0006] The technical solution of this utility model is as follows: a disposable chopsticks bagging machine, including a frame, a conveying mechanism, a feeding mechanism, a bag-supporting mechanism, and a conveying mechanism. The conveying mechanism is installed on the top of the frame. The conveying mechanism is in an asymmetrical inverted V shape.

The feeding mechanism is connected to the chopsticks forming machine at the inlet end of the conveying mechanism. The bag-supporting mechanism is connected to the discharge end of the conveying mechanism. The bag-supporting mechanism has the function of bidirectionally opening the packaging bag. The bag-supporting mechanism can slide up and down. When installing the packaging bag, the bag-supporting mechanism is at the bottom. A conveying mechanism is installed below the bag-supporting mechanism. After the chopsticks are filled, the packaging bag is conveyed out of the equipment through the conveying mechanism. The height of the conveying mechanism can be adjusted according to the amount of chopsticks in the bag.

[0007] In one embodiment, the material conveying mechanism includes a first drive wheel, a second drive wheel, a third drive wheel, a steering wheel, a material conveying belt, a material conveying motor, and a gear transmission assembly.

The steering wheel supports the material conveying belt below the second drive wheel. The material conveying motor is mounted on the upper right side of the frame, and the output shaft of the material conveying motor is driven by the end of the second drive wheel through a gear transmission assembly.

[0008] In one embodiment, the material conveying mechanism further includes a baffle bar, which is slidably mounted on the front and rear sides of the conveying belt and can be fixed.

[0009] In one embodiment, the feeding mechanism further includes an arc-shaped clamping plate, which is installed above the frame and positioned above the second transmission wheel. The position of the arc-shaped clamping plate can be vertically adjusted.

[0010] In one embodiment, the feeding mechanism further includes baffles, with baffles connected to the bottom of each baffle bar, and the baffles adjusting their positions synchronously with the baffle bars.

[0011] In one embodiment, the material conveying mechanism further includes a limiting strip. The first drive wheel, the second drive wheel and the third drive wheel are all provided with limiting grooves in their circumference. The limiting strip is provided on the inner side of the material conveying belt on the same vertical horizontal plane as the limiting groove, and the limiting strip is stuck in the limiting groove.

[0012] In one embodiment, the feeding mechanism includes a receiving hopper, a limiting plate, a baffle plate, a swing plate, a follower wheel, and a cam. The receiving hopper is located on the left side of the frame. Two limiting plates are installed in parallel inside the receiving hopper. The front and rear positions of the limiting plates can be adjusted. A baffle plate is located near the feeding end of the conveying mechanism in the receiving hopper. The height of the baffle plate can be adjusted. The baffle plate is located between the limiting plates. A swing plate is rotatably installed at the bottom of the receiving hopper. A follower wheel is provided on the swing plate. A cam is provided on the side of the first transmission wheel. The top of the cam contacts the bottom of the follower wheel.

[0013] In one embodiment, the bag-supporting mechanism includes a vertical track, a sliding mounting plate, a horizontal track, a sliding plate, a support rod, a sliding block, a hinge rod, a cylinder, and a stop block. A vertical track is vertically arranged at the rear of the frame, and a sliding mounting plate is slidably mounted on the vertical track via a slider. A horizontal track extends to the left and right sides of the front side of the sliding mounting plate, and sliding plates are slidably mounted on both the left and right sides of the horizontal track. Support rods extending downward are arranged on the front and rear sides of the bottom of the sliding plate, and the front and rear positions of the support rods can be adjusted. The support rods are located on both sides of the discharge end of the material conveying mechanism. A cylinder is rotatably connected between the sliding plates. A sliding block is slidably mounted on the vertical track below the sliding mounting plate, and a hinge rod is rotatably connected between the sliding block and the sliding plate. A stop block is fixed on the frame below the sliding mounting plate, and the top of the stop block contacts the bottom of the sliding mounting plate.

[0014] In one embodiment, the conveying mechanism includes a lifting motor, a lead screw, a lifting plate, and a conveyor belt. The lifting motor is installed on the upper rear side of the frame, and a lead screw is connected to the output shaft of the lifting motor. The lead screw is installed parallel to the vertical rail, and a lifting plate is threaded onto the lead screw. The lifting plate is slidably connected to the vertical rail via a slider, and a conveyor belt is installed at the bottom of the lifting plate, which is below the bag-supporting mechanism.

[0015] In one embodiment, a straightening mechanism is also included. The straightening mechanism is installed in the middle of the frame and includes a swing arm, a pressure rod, a hook plate, and a spring. The swing arm is rotatably installed in the middle of the frame, and the pressure rod is rotatably installed on the upper part of the swing arm. The pressure rod presses against the inner side of the conveyor belt. The hook plate is vertically installed on the frame below the swing arm, and a spring connects the hook plate and the swing arm.

[0016] Beneficial effects: The conveying mechanism of this utility model is an asymmetrical inverted V-shape. Compared with the prior art, the installation position of the packaging bag is lower, and when the chopsticks are being bagged, the bag-supporting mechanism is at its lowest position and in a closed state. The packaging bag can be quickly and conveniently placed on the bag-supporting mechanism, and then quickly fixed by the bidirectionally opening bag-supporting mechanism. At the same time, the conveying mechanism adjusts its height according to the amount of chopsticks in the packaging bag to support the packaging bag, so that the bag-supporting mechanism does not bear the weight of the packaging bag. The opening force of the bag-supporting mechanism on the packaging bag can be reduced to prevent damage to the packaging bag; the conveying belt is sleeved between the first drive wheel, the second drive wheel, and the third drive wheel. The three drive wheels provide enhanced stability and load-bearing capacity. Simultaneously, a single conveyor belt transports the chopsticks, reducing material scrambling and overcoming the problems associated with existing two-section chain conveyors. Chain conveyors are prone to chain elongation, leading to poor chain-sprocket connection and uneven material transfer. The conveyor belt overcomes these issues and reduces material jamming and downtime. When the material outlet is near the bottom of the packaging bag, a lifting motor maintains the position of the lifting plate and conveyor belt before chopstick filling begins. This ensures the packaging bag is filled from the bottom, guaranteeing fullness. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0026] Example: Disposable chopsticks bagging machine, such as Figures 1-7 As shown, the machine includes a frame 1, a conveying mechanism 2, a feeding mechanism 3, a bag-supporting mechanism 4, and a conveying mechanism 5. The conveying mechanism 2 is installed above the frame 1. The conveying mechanism 2 is an asymmetrical inverted V-shape, with the length of the discharge section being shorter than the length of the feeding section. The left side of the conveying mechanism 2 is the inlet end, and the right side is the outlet end. The feeding mechanism 3 is provided at the inlet end of the conveying mechanism 2. The feeding mechanism 3 is connected to the chopstick forming machine. The formed disposable chopsticks enter the feeding mechanism 3 and are then intermittently conveyed to the conveying mechanism 5. 2. The feeding mechanism 2 conveys the chopsticks to the packaging bag. The discharge end of the feeding mechanism 2 is connected to the bag-supporting mechanism 4. The bag-supporting mechanism 4 has the function of opening the packaging bag in both directions. The bag-supporting mechanism 4 can slide up and down. When installing the packaging bag, the bag-supporting mechanism 4 closes. After the packaging bag is put on the bag-supporting mechanism 4, the bag-supporting mechanism 4 opens to fix the packaging bag. A conveying mechanism 5 is installed below the bag-supporting mechanism 4. After the packaging bag is filled with chopsticks, it is conveyed out of the equipment through the conveying mechanism 5. The conveying mechanism 5 can adjust the height according to the amount of chopsticks in the bag.

[0027] Disposable chopsticks bagging machine: When bagging chopsticks, the bag-supporting mechanism 4 first moves to the bottom. Furthermore, the conveying mechanism 2 of this application has an asymmetrical inverted V-shape on both sides. Compared with existing technologies, the installation position of the packaging bag is lower, facilitating bag installation. Then, the bag-supporting mechanism 4 closes, placing the bag opening over it. The bag-supporting mechanism 4 then opens to secure the bag opening. At this time, the conveying mechanism 5 moves upward to the top, and the bottom of the packaging bag contacts the conveying surface of the conveying mechanism 5. The formed chopsticks enter the feeding mechanism 3. The feeding mechanism 3 then intermittently places the chopsticks on the conveying mechanism 2, which then conveys the chopsticks into the packaging bag at the bag-supporting mechanism 4. As the number of chopsticks in the packaging bag increases, the conveying mechanism 5 slowly moves downward. The bottom of the bag also moves downwards to accommodate the increasing number of chopsticks inside. After the bag is filled with chopsticks, the bag-supporting mechanism 4 closes, and the conveying mechanism 5 transports the bag away after the chopsticks are filled, replacing it with a new bag to continue the bagging process. Compared with the prior art, when bagging chopsticks, the bag-supporting mechanism 4 is at its lowest position and in a closed state, allowing the bag to be placed quickly and conveniently on it. The bidirectionally opening bag-supporting mechanism 4 then quickly secures the bag. At the same time, the conveying mechanism 5 adjusts its height according to the amount of chopsticks in the bag, supporting it so that the bag-supporting mechanism 4 does not bear the weight of the bag. The force exerted by the bag-supporting mechanism 4 on the bag can be reduced to prevent damage to the bag.

[0028] like Figure 2 , Figure 3 and Figure 4As shown, the material conveying mechanism 2 includes a first transmission wheel 21, a second transmission wheel 22, a third transmission wheel 23, a steering wheel 24, a material conveying belt 25, a material conveying motor 26, a gear transmission group 27, a stop bar 28, an arc-shaped clamping plate 29, a baffle 210, and a limiting bar 212. The first transmission wheel 21 is rotatably mounted on the lower left side of the frame 1 via a shaft, the second transmission wheel 22 is rotatably mounted on the middle right side of the frame 1 via a shaft, and the third transmission wheel 23 is rotatably mounted on the upper right side of the frame 1 via a shaft. A steering wheel 24 is rotatably mounted on the frame 1 below 23. A conveyor belt 25 is fitted between the first drive wheel 21, the second drive wheel 22, and the third drive wheel 23. The three drive wheels provide stronger conveying stability and load-bearing capacity. The steering wheel 24 supports the conveyor belt 25 below the second drive wheel 22, increasing the contact area between the conveyor belt 25 and the drive wheels, thus improving conveying stability. A conveyor motor 26 is bolted to the upper right of the frame 1. The output shaft of the conveyor motor 26 is driven by a gear transmission group 27 to the end of the second drive wheel 22. A stop bar 28 is slidably mounted on the front and rear sides of the conveyor belt 25. The stop bar 28 has oblong holes extending forward and backward, allowing it to be fixed by bolts passing through the oblong holes. An arc-shaped clamping plate 29 is mounted above the frame 1, positioned above the second drive wheel 22. The arc-shaped clamping plate 29 has oblong holes extending vertically, allowing it to be fixed by bolts passing through the oblong holes. The position of 9 can be adjusted vertically. The bottom of each baffle 28 is connected to a baffle 210. The baffle 210 adjusts its position synchronously with the baffle 28. The first drive wheel 21, the second drive wheel 22 and the third drive wheel 23 are all provided with limit grooves 211 in the circumference. The inner side of the conveyor belt 25 located on the same vertical horizontal plane as the limit groove 211 is provided with a limit strip 212. The limit strip 212 is stuck in the limit groove 211, so that the conveyor belt 25 will not be displaced during the conveying of chopsticks.

[0029] Material conveying mechanism 2: Before conveying chopsticks, adjust the front and rear positions of the baffle bar 28 according to the length of the chopsticks. The baffle bar 28 limits the front and rear movement of the conveyed chopsticks. After the position of the baffle bar 28 is adjusted, adjust the height of the arc-shaped clamping plate 29 according to the thickness of the chopsticks to prevent the chopsticks from colliding with the arc-shaped clamping plate 29 during conveying. At the same time, when the conveying direction of the chopsticks changes, the chopsticks will not fall off the conveyor belt 25. Then the chopsticks conveying operation begins. The chopsticks are clamped on the conveyor belt 25, and the conveyor motor 26 is controlled to rotate counterclockwise. Through the gear transmission group 27, the second transmission wheel 22 is driven to rotate clockwise, so that the conveyor belt... The chopsticks are conveyed by rotating clockwise 25 and are placed into the packaging bag fixed at 4 points of the bag-supporting mechanism. When the chopsticks fall into the packaging bag, the baffle 210 limits the chopsticks so that they can enter the packaging bag more neatly. This application uses a conveyor belt 25 to convey chopsticks, which can reduce the problem of messy material and overcome the problem of messy material caused by the two-section chain conveying method in the prior art. At the same time, the chain conveying method is prone to chain elongation, which can cause poor connection between the chain and the sprocket and result in uneven material transmission. The conveyor belt 25 can overcome the above problems and also reduce the problems of equipment jamming and downtime.

[0030] like Figure 5 As shown, the feeding mechanism 3 includes a receiving hopper 31, a limiting plate 32, a baffle plate 33, a swing plate 34, a follower wheel 35, and a cam 36. The receiving hopper 31 is fixed to the left side of the frame 1 by bolts. The receiving hopper 31 is used to receive disposable chopsticks after molding. Two limiting plates 32 are installed in parallel inside the receiving hopper 31. The upper side of each limiting plate 32 is provided with a waist-shaped hole extending forward and backward. The forward and backward position of the limiting plate 32 can be adjusted. The limiting plate 32 is fixed by bolts passing through the waist-shaped holes. A baffle plate 33 is provided near the feeding end of the conveying mechanism 2 in the hopper 31. The upper part of the baffle plate 33 has an elongated waist-shaped hole. The height of the baffle plate 33 can be adjusted. The position of the baffle plate 33 is fixed by bolts passing through the elongated hole. The baffle plate 33 is located between the limiting plates 32. A swing plate 34 is rotatably installed at the bottom of the receiving hopper 31. A follower wheel 35 is provided on the swing plate 34. A cam 36 is provided on the side of the first transmission wheel 21. The top of the cam 36 contacts the bottom of the follower wheel 35.

[0031] Feeding Mechanism 3: Before feeding the chopsticks, adjust the height of the baffle plate 33 so that the gap between the bottom of the baffle plate 33 and the swing plate 34 is adjusted, thereby controlling the speed at which the chopsticks enter the feeding mechanism 2. At the same time, adjust the distance between the limiting plates 32. The limiting plates 32 are used to limit the front and rear ends of the chopsticks. After the positions of the limiting plates 32 and the baffle plate 33 are adjusted, the bagging operation of the chopsticks begins. During the rotation of the first transmission wheel 21, the cam 36 is driven to rotate, which in turn drives the follower wheel 35 to move up and down, causing the swing plate 34 to swing up and down. The swing of the swing plate 34 changes the gap between the swing plate 34 and the baffle plate 33, and the chopsticks intermittently enter the feeding belt 25 through the gap for feeding.

[0032] like Figure 6 and Figure 7 As shown, the bag-supporting mechanism 4 includes a vertical track 41, a sliding mounting plate 42, a horizontal track 43, a sliding plate 44, a support rod 45, a sliding block 46, a hinge rod 47, a cylinder 48, and a stop block 49. The vertical track 41 is bolted to the rear of the frame 1. A sliding mounting plate 42 is slidably mounted on the vertical track 41 via a slider. A horizontal track 43 is bolted to the left and right sides of the front side of the sliding mounting plate 42. Sliding plates 44 are slidably mounted on both the left and right sides of the horizontal track 43. Support rods 45 extend downwards on both the front and rear sides of the bottom of the sliding plate 44. Waist-shaped holes are extended forward and backward on the sliding plate 44 above the support rods 45. The front and rear positions of 45 can be adjusted. It can be fixed by screwing the bolt through the waist-shaped hole into the support rod 45. The support rod 45 is located on the left and right sides of the discharge end of the material conveying mechanism 2. The sliding plates 44 are rotatably connected by a cylinder 48. By controlling the extension and retraction of the cylinder 48, the sliding plates 44 are driven to separate or close. A sliding block 46 is slidably installed on the vertical track 41 below the sliding mounting plate 42. The sliding block 46 and the sliding plate 44 are rotatably connected by a hinge rod 47. A stop block 49 is fixed on the frame 1 below the sliding mounting plate 42. The top of the stop block 49 contacts the bottom of the sliding mounting plate 42, so that the sliding mounting plate 42 and its device cannot move downward.

[0033] Bag-supporting mechanism 4: Before the chopsticks are bagged, the bottom of the sliding mounting plate 42 contacts the stop block 49. At this time, the sliding mounting plate 42 is at its lowest position. Then, the control cylinder 48 retracts, causing the sliding plates 44 on both sides to close, so that the supporting rods 45 close, making it easier to install the packaging bag. At this time, the opening of the packaging bag is placed between the supporting rods 45, and the control cylinder 48 extends, causing the sliding plates 44 to separate, so that the supporting rods 45 separate and open and fix the opening of the packaging bag.

[0034] like Figure 6 and Figure 7As shown, the conveying mechanism 5 includes a lifting motor 51, a lead screw 52, ​​a lifting plate 53, and a conveyor belt 54. The lifting motor 51 is fixedly installed on the upper rear side of the frame 1 by bolts. The output shaft of the lifting motor 51 is connected to the lead screw 52. The bottom end of the lead screw 52 is rotatably connected to the frame 1. The lead screw 52 is installed parallel to the vertical rail 41. The lifting plate 53 is threadedly connected to the lead screw 52. The lifting plate 53 is slidably connected to the vertical rail 41 by a slider. The conveyor belt 54 is installed at the bottom of the lifting plate 53 and is located below the bag-supporting mechanism 4.

[0035] Conveying Mechanism 5: After the packaging bag is installed on the bag-supporting mechanism 4, the lifting motor 51 drives the lead screw 52 to rotate, causing the lifting plate 53 and the conveyor belt 54 to move upward. When the lifting plate 53 moves upward and contacts the sliding block 46, it pushes the bag-supporting mechanism 4 and the packaging bag on it to move upward. When the discharge port of the conveying mechanism 2 is close to the bottom of the packaging bag, the lifting motor 51 maintains the position of the lifting plate 53 and the conveyor belt 54, and then the chopsticks filling operation begins. In this way, when filling the packaging bag with chopsticks, it can start from the bottom, ensuring the fullness of the packaging bag. As the amount of chopsticks in the packaging bag increases, the bottom of the packaging bag and the conveyor belt... At the top contact point 54, the conveyor belt 54 supports the packaging bag. At this time, the lifting motor 51 drives the lifting plate 53 and the conveyor belt 54 to move downward. During the downward movement, the bottom of the packaging bag is always in contact with the top of the conveyor belt 54, so that the conveyor belt 54 can always support the packaging bag. After the sliding mounting plate 42 contacts the stop block 49, the bag supporting mechanism 4 stops moving downward, and the lifting plate 53 and the conveyor belt 54 continue to move downward. The packaging bag is straightened until the packaging bag completes the chopsticks filling operation. The bag supporting mechanism 4 releases the packaging bag, and the conveyor belt 54 transports the packaged bag with chopsticks to the next location and replaces it with a new packaging bag for the next operation.

[0036] like Figure 2 and Figure 3 As shown, it also includes a straightening mechanism 6. The straightening mechanism 6 is installed in the middle of the frame 1. The straightening mechanism 6 includes a swing arm 61, a pressure rod 62, a hook plate 63, and a spring 64. The swing arm 61 is rotatably installed in the middle of the frame 1. The pressure rod 62 is rotatably installed on the upper part of the swing arm 61. The pressure rod 62 presses against the inner side of the conveyor belt 25. The hook plate 63 is vertically fixed to the frame 1 below the swing arm 61 by bolts. The spring 64 connects the hook plate 63 and the swing arm 61. According to the tension of the conveyor belt 25, the position of the connection point between the spring 64 and the hook plate 63 is adjusted. The lower the connection point between the spring 64 and the hook plate 63, the higher the tension of the conveyor belt 25. The higher the connection point between the spring 64 and the hook plate 63, the lower the tension of the conveyor belt 25.
