Description

Technical Field

[0001] This utility model belongs to the field of ton bag packaging machines, and specifically relates to a ton bag packaging machine for precipitated silica. Background Technology

[0002] Silica, as an important chemical additive, is widely used in rubber, coatings, toothpaste, and other fields. In the ton bag packaging process, to reduce dust and improve efficiency, automated packaging equipment is typically used for quantitative filling. To facilitate subsequent transfer and adapt to loading and unloading processes, traditional ton bag packaging machines often use a lifting and weighing method. However, existing technology has insufficient safety in traditional ton bag packaging machines. To facilitate filling, the ton bags are often suspended during filling, especially when they are full. To avoid folding and affecting capacity, the ton bags often need to be lifted in advance, which increases the stress time on the lifting mechanism and makes it easy to damage the lifting or weighing mechanism. Furthermore, if the lifting mechanism loses power or malfunctions and becomes unloaded, the ton bags or lifting mechanism may fall directly due to their weight, impacting the equipment frame and other structures, resulting in low safety and potential damage to the equipment and danger to workers. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To overcome the shortcomings of existing technologies, a precipitated silica ton bag packaging machine is proposed. This addresses the safety issues of traditional ton bag packaging machines. To facilitate filling, the ton bags are often suspended during filling, especially when they are quite full. To prevent folding and other issues that could affect capacity, the ton bags often need to be lifted prematurely. This increases the stress time on the lifting mechanism, making it prone to damage. Furthermore, if the lifting mechanism loses power or malfunctions and becomes unloaded, the ton bags or lifting mechanism may fall due to their weight, impacting the equipment frame and other structures. This low safety level poses a risk of equipment damage and worker hazards.

The top of the assembly is fitted with an assembly plate via the hydraulic buffer, and a buffer block is fixed to the top of the assembly plate. Limiting grooves are provided on both sides of the lifting slide of the lifting frame. The limiting grooves are used to limit the sliding of the buffer block within the lifting slide. The maximum force on the safety pin is less than the maximum force on the hydraulic buffer.

[0009] Furthermore, the fall arrestor also includes a pressure sensor and a warning device. The pressure sensor is mounted between the mounting plate and the buffer block, and the warning device is mounted inside the mounting plate. The warning device is electrically connected to the pressure sensor.

[0010] Furthermore, the buffer block is made of an elastic material.

The receiving hopper is fixedly connected to the first assembly ring, the third assembly ring, or the connecting rod. Three or more assembly rods are fixed to the side end face of the first assembly ring. The end of the assembly rod away from the first assembly ring is fitted with the lifting structure.

[0013] Furthermore, the hoisting structure includes a movable rod, a hoisting head, a venting connector, a switch groove, a movable connecting head, a connecting seat, a first wheel body, a connecting piece, a second wheel body, and a piston head. The second wheel body is mounted on the mounting rod via a shaft, and the second wheel body is connected to the first wheel body via a connecting piece. The first wheel body is mounted on the connecting seat via a shaft, and the bottom of the connecting seat is rotatably connected to the hoisting head via the movable connecting head.

[0018] (III) Beneficial Effects

[0019] One of the above technical solutions has the following advantages or beneficial effects:

[0020] Packaging machines equipped with lifting platforms and anti-fall devices utilize a triple-buffered anti-fall combination of rubber buffer blocks, hydraulic buffers, and safety pins. During ton bag filling, the lifting platform supports the ton bags, gradually lowering them to ensure the bags remain supported at the bottom. Only after filling is complete is the lifting platform lowered again for suspended weighing. This prevents the ton bags from being in a filling state for extended periods or requiring pre-emptive lifting, ensuring smooth bag filling, preventing folding and other issues affecting bag capacity, reducing stress on the lifting and weighing mechanisms, increasing service life and safety. Furthermore, in the event of a fall, the triple-buffered design provides more buffer space and a longer buffer time, better preventing impact damage to the equipment frame and other structures, ensuring safe operation.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0029] Example 1:

[0030] This utility model provides a fumed carbon black ton bag packaging machine: its structure includes a lifting platform 1, a bag filling and weighing mechanism 2, a lifting frame 3, a lifting trolley 4 and an anti-fall device 5. The lifting frame 3 is equipped with a lifting trolley 4, and the bag filling and weighing mechanism 2 is fixed on one side of the lifting trolley 4. The lifting platform 1 is equipped at the bottom of the lifting frame 3, and the lifting platform 1 is located directly below the bag filling and weighing mechanism 2.

[0031] The lifting frame 3 has a lifting slide 301 on its side end face;

[0032] The fall arrestor 5 includes an assembly 501, a hydraulic buffer 502, a limiting groove 503, an assembly plate 504, a buffer block 505, and a safety pin 508. The assembly 501 is mounted in the lifting slide 301 of the lifting frame 3 via the safety pin 508. The top of the assembly 501 is mounted with the assembly plate 504 via the hydraulic buffer 502. The top of the assembly plate 504 is fixed with the buffer block 505. The lifting slide 301 of the lifting frame 3 is provided with limiting grooves 503 on both sides. The limiting grooves 503 are used to limit the sliding of the buffer block 505 in the lifting slide 301. The maximum force of the safety pin 508 is less than the maximum force of the hydraulic buffer 502.

[0033] The fall arrestor 5 further includes a pressure sensor 506 and a warning device 507. The pressure sensor 506 is mounted between the mounting plate 504 and the buffer block 505, and the warning device 507 is mounted inside the mounting plate 504. The warning device 507 is electrically connected to the pressure sensor 506.

[0034] The buffer block 505 is made of elastic materials such as rubber, polyurethane elastomer or EVA plastic.

[0035] The lifting trolley 4 includes a first sprocket set 401, lifting pulleys 402, a frame 403, a chain 404, a second sprocket set 405, and a motor 406. The first sprocket set 401 is mounted on the upper side inside the lifting frame 3, and the second sprocket set 405 is mounted on the lower side inside the lifting frame 3. Lifting pulleys 402 are mounted on all four sides of the frame 403 via axles. The lifting pulleys 402 are mounted in the lifting groove 301 on the side away from the frame 403. One end of the chain 404 is fixed to the bottom of the frame 403, and the other end of the chain 404 passes through the second sprocket set 405 and the first sprocket set 401 and is fixedly connected to the top of the frame 403. The motor 406 is used to drive the second sprocket set 405 to rotate.

[0036] In use, the ton bag is assembled through the bagging and weighing mechanism 2, then the lifting trolley 4 is raised, and the lifting platform 1 is simultaneously raised to connect with the bottom of the ton bag. Then, the bag is filled through the bagging and weighing mechanism 2. During the filling process, the lifting platform 1 supports the ton bag and gradually lowers it to ensure the ton bag remains in a supported assembly state at the bottom. Only after filling is completed is the lifting platform lowered again for suspended weighing. This avoids the ton bag being in a filling state for a long time or requiring early lifting, and ensures smooth bag filling, preventing folding and other issues affecting the filling capacity. It also reduces the stress on the lifting and weighing mechanisms, increasing service life and safety. Furthermore, in the event of a fall, the lifting trolley 4 will first impact the buffer block 505. This allows the buffer block 505 to slide within the limiting groove 503. Since the buffer block 505 is made of elastic material, it provides the first layer of buffering. At the same time, the buffer block 505 will press against the hydraulic buffer 502 for the second layer of buffering. If the impact force is too large, the buffer block 505 will provide some obstruction before leaving the limiting groove 503. As the force increases, if the buffer block 505 leaves the limiting groove 503 and continues to compress towards the hydraulic buffer 502, and before exceeding the limit of the hydraulic buffer 502, it will press against the assembly 501 to break the safety pin 508 for the third layer of buffering. This provides more buffer space and a longer buffer time, which can better avoid impact damage to the equipment frame and other structures, and ensure the safety of use.

The second assembly ring 204 is fixedly connected to the lifting trolley 4. The third assembly ring 205 is assembled on the top of the second assembly ring 204 through the weighing sensor 207. The bottom of the third assembly ring 205 is fixedly connected to the first assembly ring 203 through the connecting rod 208. The receiving hopper 206 is assembled through the inner ring ends of the first assembly ring 203, the second assembly ring 204, and the third assembly ring 205. The receiving hopper 206 is fixedly connected to the first assembly ring 203, the third assembly ring 205, or the connecting rod 208. Three or more assembly rods 202 are fixed on the side end face of the first assembly ring 203. The lifting structure 201 is assembled on the end of the assembly rod 202 away from the first assembly ring 203.

[0039] The hoisting structure 201 includes a movable rod 20101, a hoisting head 20102, a vent connector 20103, a switch slide 20104, a movable connector 20105, a connecting seat 20106, a first wheel body 20107, a connecting piece 20108, a second wheel body 20109, and a piston head 20110. The second wheel body 20109 is mounted on the mounting rod 202 via a shaft. The second wheel body 20109 and the first wheel body 20107 are connected via a connecting piece 20108. The first wheel body 20107 is mounted on the connecting seat 20106 via a shaft. The bottom of the connecting seat 20106 is connected via a movable joint. The connector 20105 is rotatably connected to the lifting head 20102. The lifting head 20102 has a switch slide groove 20104 inside. The piston head 20110 is assembled in the switch slide groove 20104. One end of the piston head 20110 is fixedly connected to one end of the movable rod 20101. The bottom of the lifting head 20102 has an opening. The movable rod 20101 is used to control the opening and closing of the bottom opening of the lifting head 20102. The end of the piston head 20110 away from the movable rod 20101 in the switch slide groove 20104 communicates with the vent connector 20103. The vent connector 20103 is located on the side end face of the lifting head 20102.

[0040] The connector 20108 is a rope, and the first wheel 20107 and the second wheel 20109 are pulleys.

[0041] The switch slide 20104 and the movable rod 20101 are concentric arc-shaped bodies.

[0042] Wherein, the maximum stroke of the piston head 20110 within the switch slide groove 20104 is greater than the stroke of the movable rod 20101 disengaging from the bottom opening of the lifting head 20102.

[0043] In use, the receiving hopper 206 facilitates the bagging and guiding of silica. At the same time, the first wheel body 20107 and the second wheel body 20109 connected by ropes can be easily adjusted in direction to accommodate ton bags at different hanging positions. When the ton bag is hung up, gas or liquid can be introduced through the vent connector 20103, causing the piston head 20110 to slide in the switch slide groove 20104, thereby driving the movable rod 20101 to slide on the lifting head 20102. It can also control the sealing or opening of the bottom opening of the lifting head 20102, which facilitates the assembly of ton bags. The rest of the structure and effect remain unchanged.

[0045] Compared to the previous embodiments, the connector 20108 in this embodiment is a chain, the first wheel 20107 and the second wheel 20109 are sprockets, and the rest of the structure and effects remain unchanged.
