Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a bag dropping and stacking device, particularly a novel automatic bag dropping and stacking device. Background Technology

[0002] Large quantities of granular and powdery goods, including cement, fertilizer, grain, feed, and chemical raw materials, are currently packaged in woven bags, which is the most common packaging method. The handling, transfer, and loading / unloading of bagged materials rely on manual stacking of each bag, supplemented by some mechanical equipment for lifting, transfer, and unloading. This not only consumes a lot of manpower and resources, resulting in high work intensity and low efficiency, but also easily leads to damage to the bagged packaging and loss of goods. Bagged materials used for powdery goods generate a large amount of dust during handling, polluting the environment and seriously threatening the health of workers.

[0003] For example, an automatic bag-dropping and stacking device disclosed in Chinese patent literature (application number: 201610687848.5) includes a support base, a positioning baffle, a rotating shaft one, and a rotating shaft two. A double door one is fixedly connected to rotating shaft one, and a double door two, opposite to double door one, is fixedly connected to rotating shaft two. A drive structure for driving rotating shaft one and rotating shaft two to rotate synchronously in opposite directions is provided in front of the positioning baffle. The drive structure is connected to a controller. A sensor switch for sensing the position of the bag is also provided on the positioning baffle. The sensor switch is connected to the controller. The drive structure includes a box with a cavity one at the front and a cavity two at the rear. Input shaft one and input shaft two are provided inside the box. Input shaft one and input shaft two rotate synchronously in opposite directions. Input shaft one is driven to rotating shaft one through a crank-connecting rod mechanism one, and input shaft two is driven to rotating shaft two through a crank-connecting rod mechanism two. However, the structure of this automatic bag-dropping and stacking device is relatively complex and the size is relatively large. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a novel automatic bag-dropping and stacking device that is compact in structure and reliable and stable in operation.

[0005] The purpose of this utility model can be achieved through the following technical solution: a novel automatic bag-dropping and stacking device, comprising a base and a side plate vertically fixed to one end of the base plate, wherein two horizontally arranged rotating shafts are axially fixed to the base, and the two rotating shafts can rotate synchronously in opposite directions, and double doors are respectively fixed to the inner sides of the two rotating shafts, characterized in that two parallel input shafts are axially fixed to the side plate, and a crank-connecting rod mechanism is provided between the two input shafts and the two rotating shafts, and the crank-connecting rod mechanism is close to the outer side wall of the side plate, and a driving mechanism is fixed to the inner side wall of the side plate, and the driving mechanism can drive the two crank-connecting rod mechanisms to rotate synchronously in opposite directions.

[0006] The new automatic bag-dropping and stacking device is connected to the input device, which conveys the bagged material to two double doors. The drive mechanism drives the corresponding double doors to rotate through the crank-connecting rod mechanism, causing the double doors to open and the bagged material to fall through the double doors. Then the drive mechanism drives the double doors to reset. Since the crank-connecting rod mechanism is close to the outer wall of the side plate and the drive mechanism is fixed to the inner wall of the side plate, this new automatic bag-dropping and stacking device has the advantages of compact structure and reliable and stable operation.

[0007] In the aforementioned novel automatic bag-dropping and stacking device, the drive mechanism includes a gearbox whose housing is fixedly connected to the inner wall of the side plate, and a motor whose housing is fixedly connected to the gearbox housing. The output end of the gearbox is fixedly connected to one of the input shafts, and the main shaft of the motor is fixedly connected to the input end of the gearbox. The motor and gearbox are located inside the side plate, giving this novel automatic bag-dropping and stacking device the advantages of reliable and stable operation and a compact structure.

[0008] In the aforementioned novel automatic packing and stacking device, the driving mechanism is a geared motor whose housing is fixedly connected to the inner wall of the side plate, and the main shaft of the geared motor is fixedly connected to one of the input shafts. This configuration offers the advantages of reliable and stable operation as well as a compact structure.

[0009] In the aforementioned novel automatic bag-dropping and stacking device, the crank-connecting rod mechanism includes a crank, a swing arm, and a connecting rod. The crank is fixedly connected to the corresponding input shaft, the swing arm is fixedly connected to the corresponding rotating shaft, and both ends of the connecting rod are fixedly connected to the corresponding crank and the swing arm, respectively. The drive mechanism drives the two rotating shafts to rotate synchronously through the crank-connecting rod mechanism, which has the advantages of reliable operation and structural reliability.

[0010] In the aforementioned novel automatic packing and stacking device, the crank employs gears fixedly connected to the input shafts. Two gears mesh, and these gears are close to the outer wall of the side plate. Through the two meshing gears, the two input shafts rotate synchronously in opposite directions, offering the advantage of reliable operation.

[0011] In the aforementioned novel automatic packing and stacking device, a cover is fixedly connected to the outer wall of the side plate, and both sets of the crank-connecting rod mechanisms are located inside the cover. Protecting the crank-connecting rod mechanisms with the cover provides advantages such as good protection and a compact and reliable structure.

[0012] In the aforementioned novel automatic bag-dropping and stacking device, the housing is provided with several doors, and these doors are capable of opening and closing relative to the housing. By providing these doors, it is convenient to add lubricating oil to the crank-connecting rod mechanism inside the housing, offering the advantage of ease of use.

[0013] In the aforementioned novel automatic bag-dropping and stacking device, a sensing strip is fixedly connected to one of the gears, and a sensing switch is fixedly connected to the side plate. When the gear drives the sensing strip to one side, the sensing switch can sense the sensing strip. In the aforementioned novel automatic bag-dropping and stacking device, this device also includes a sensing device capable of sensing bagged goods located near the inner wall of the side plate.

[0014] In the aforementioned novel automatic bag-dropping and stacking device, the sensing device includes a swing arm hinged in the middle to the upper end of the side plate.

When the lower side of one end of the swing arm is pushed to the inner wall of the side plate, the second sensing switch can sense the second sensing strip.

[0015] In the aforementioned novel automatic bag-dropping and stacking device, the swing arm includes a long, narrow connecting portion. Both ends of the connecting portion are connected to a rod-shaped force-receiving portion and a limiting portion, respectively. The lower end of the limiting portion abuts against the outer wall of the side plate. The force-receiving portion and the limiting portion are located on the inner and outer sides of the side plate, respectively. The connecting portion is hinged to the upper end of the side plate, and the sensing strip is fixedly connected to the connecting portion. This configuration allows the swing arm to swing at a set angle, offering advantages such as simple structure and reliable operation.

[0016] In the aforementioned novel automatic bag-dropping and stacking device, the device also includes a controller. The first and second induction switches, as well as the motor, are all connected to the controller. The input device conveys the bagged material to two double doors. The bagged material pushes the force-bearing part, causing the swing arm to rotate. This causes the second induction switch to sense the second sensing strip. The second induction switch sends a signal to the controller, which then controls the motor to drive the gears to rotate. Through the corresponding swing arm and connecting rod, the double doors rotate, opening them. The bagged material falls through the double doors, and the gears continue to rotate until the double doors are in a horizontal, closed state. At this point, the first induction switch senses the first sensing strip on the gear and sends a signal to the controller. The controller then stops the motor. This device has the advantages of reliable and stable operation and high efficiency.

The motor and gearbox are located on the inside of the side plate, which makes this new automatic bag dropping and stacking device reliable, stable and compact in structure; 3. The crank and connecting rod mechanism is protected by a cover, which has the advantages of good protection and compact and reliable structure. Attached Figure Description

The motor 7b and the gearbox 7a are located on the inner side of the side plate 2, which makes the new automatic packing and stacking device reliable, stable and compact.

[0026] Alternatively, the drive mechanism 7 is a geared motor 7b whose housing is fixed to the inner wall of the side plate 2, and the main shaft of the geared motor 7b is fixed to one of the input shafts 5.

[0027] The crank-connecting rod mechanism 6 includes a crank 6a, a rocker arm 6b, and a connecting rod 6c. The crank 6a is fixedly connected to the corresponding input shaft 5, the rocker arm 6b is fixedly connected to the corresponding rotating shaft 3, and both ends of the connecting rod 6c are fixedly connected to the corresponding crank 6a and rocker arm 6b, respectively. The crank 6a uses a gear fixedly connected to the input shaft 5. The two gears mesh and are close to the outer wall of the side plate 2. The drive mechanism 7 drives the two rotating shafts 3 to rotate synchronously through the crank-connecting rod mechanism 6, which has the advantages of reliable operation and structural reliability. Through the two meshing gears, the two input shafts 5 rotate synchronously in opposite directions, which also has the advantage of reliable operation.

[0028] A sensing strip 10 is fixedly connected to one of the gears, and a sensing switch 11 is fixedly connected to the side plate 2. When the gear drives the sensing strip 10 to one side of the sensing strip 10, the sensing switch 11 can sense the sensing strip 10.

[0029] A cover 8 is fixed to the outer side wall of the side plate 2. Both sets of crank connecting rod mechanisms 6 are located inside the cover 8. The cover 8 is provided with three doors 9, and the doors 9 can be opened and closed relative to the cover 8, which makes it convenient to add lubricating oil to the crank connecting rod mechanism 6 inside the cover 8, and has the advantage of being easy to use.

[0030] The device also includes a sensing device 12 capable of sensing bagged goods located near the inner wall of the side panel 2. The sensing device 12 includes a swing arm 12a hinged at the middle of the upper end of the side panel 2. The swing arm 12a is located between the two double doors 4. The lower side of one end of the swing arm 12a can be close to the inner wall of the side panel 2. A second sensing strip 12b is also fixedly connected to the swing arm 12a.

It has the advantages of simple structure and reliable operation.

[0032] The new automatic bag dropping and stacking device also includes a controller, and induction switch 11, induction switch 2 12c and motor 7b are all connected to the controller.

[0033] The input device conveys bagged materials to two double doors 4. The bagged materials push the force-receiving part 12a2, causing the swing arm 12a to rotate. This causes the second induction switch 12c to sense the second induction strip 12b. The second induction switch 12c sends a signal to the controller, which controls the motor 7b to drive the gear to rotate. Through the corresponding swing arm 6b and connecting rod 6c, the double doors 4 rotate, causing the double doors 4 to open. The bagged materials fall through the double doors 4. The gear continues to rotate until the double doors 4 are in a horizontal and closed state. At this time, the first induction switch 11 senses the first induction strip 10 on the gear and sends a signal to the controller. The controller controls the motor 7b to stop rotating. This device has the advantages of reliable and stable operation and high efficiency. At the same time, this new automatic bag-dropping and stacking device has the advantages of compact structure and reliable and stable operation.
