Description

Technical Field

[0001] The invention relates to the technical field of packaging, in particular to a bag clamping hopper mechanism with an air cavity. Background Art

[0002] Packaging equipment plays a vital role in industries such as chemicals and fertilizers. Products in these industries need to be packaged accurately and efficiently to meet market demand and transportation, storage and other requirements.

[0003] At present, there are many types of bag clamping mechanisms in packaging equipment in the chemical, fertilizer and other industries. Whether it is a storage or non-storage packaging machine, most of them use the door panel opening and closing method to unload materials, and clamp the packaging bag through the door panel structure to realize the operation mode of unloading to packaging bags.

[0004] Considering that in the process of clamping the two sides of the packaging bag through the door panel, due to the lack of effective sealing and control measures at the bag mouth, dust is easily generated. This dust will not only pollute the packaging environment and affect the health of operators, but also may cause product losses and increase the production costs of enterprises. At the same time, dust may also have adverse effects on the surrounding environment, which does not meet the environmental protection requirements of modern industry. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a bag clamping hopper mechanism with an air chamber, which solves the problem of dust being easily generated due to the lack of effective sealing and control measures at the bag opening during the process of clamping the two sides of the packaging bag through the door panels.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a bag clamping hopper mechanism with an air chamber, comprising a hopper shell, the inner wall of the hopper shell is rotatably connected with a rotating shaft, the rotating shaft is provided with two groups, the outer wall of one group of the rotating shafts is fixedly connected with a bag clamping door panel A, and the outer wall of the other group of the rotating shafts is fixedly connected with a bag clamping door panel B, the inner wall of the hopper shell is hinged with a door panel cylinder, the output end of the door panel cylinder is hinged with the bottom of the bag clamping door panel A, the outer wall of the bag clamping door panel B is hinged with the bag clamping cylinder, the outer wall of the bag clamping door panel A is hinged with the output end of the bag clamping cylinder, the inner wall of the hopper shell is threadedly connected with a threaded rod, and one end of the threaded rod is rotatably connected with a bag closing adjustment plate;

[0007] The outer wall of the hopper shell is provided with a cavity auxiliary mechanism. When the bag clamping door panel A and the bag clamping door panel B move outward to clamp the packaging bag, the cavity auxiliary mechanism assists in adsorbing the cavity position formed in the center of the device to reduce dust pollution. At the same time, the pore size of the activated carbon filter is changed by rotation. When bagging materials of different sizes, the adsorption efficiency is guaranteed and the filtering effect is improved.

[0008] Preferably, an air chamber plate is fixedly connected to the outer wall of the hopper shell, and a sealing strip is fixedly connected to the outer walls of the bag clamping door panel A and the bag clamping door panel B.

[0009] Preferably, the top of the bag closing adjustment plate is slidably connected to the inner wall of the hopper shell, the outer wall of the bag closing adjustment plate is fixedly connected with a bag clamping plate, and the inner wall of the bag clamping plate is plugged into the outer wall of the sealing strip.

[0010] Preferably, the cavity auxiliary mechanism includes: a shell, an inner wall of the shell is fixedly connected to a blower, the inner wall of the shell is fixedly connected to a partition plate, the bottom of the shell is rotatably connected to an outer rod, and the outer wall of the outer rod is fixedly connected to an activated carbon filter.

[0011] Preferably, the inner wall of the outer shell is slidably connected with an inclined panel, the bottom of the inclined panel is elastically connected to the inner wall of the outer shell through a spring A, the outer wall of the activated carbon filter is fixedly connected with an extrusion plate, the inner wall of the outer rod is slidably connected with the inner rod, the outer wall of the inner rod is fixedly connected with a slider, and the inner wall of the outer rod is elastically connected to the outer wall of the slider through a spring B.

[0012] Preferably, a plug-in block is fixedly connected to the outer wall of the inner rod, and a limiting ring is fixedly connected to the outer wall of the outer shell.

[0013] Preferably, the inner wall of the outer rod is fixedly connected to one end of the spring B, and the other end of the spring B is fixedly connected to the outer wall of the slider.

[0014] Preferably, a slot is provided on the inner wall of the limiting ring, and the inner wall of the slot is plugged into the outer wall of the plug-in block.

[0015] Preferably, the bottom of the inclined plate is fixedly connected to one end of the spring A, and the other end of the spring A is fixedly connected to the inner wall of the shell.

[0016] Preferably, the outer wall of the outer shell is fixedly connected to the outer wall of the hopper shell by bolts, and the outer wall of the sliding block is slidably connected to the inner wall of the outer rod.

[0017] Working principle: Open the bag opening, and make the front and rear sides of the bag opening contact with the bag clamping door panel A and the bag clamping door panel B respectively, and start the door panel cylinder and the bag clamping cylinder, so that the door panel cylinder drives the bag clamping door panel A to rotate outward, and the bag clamping cylinder drives the bag clamping door panel B to flip outward at the same time, so that the bag clamping door panels A and B cooperate with the bag closing adjustment plate to clamp and fix the two sides of the bag opening of the packaging bag.

[0018] At the same time, the bag closing adjustment plate can still be adjusted for the second time by rotating the threaded rod, so that the inner wall of the bag closing adjustment plate is squeezed with the sealing strip, further improving the clamping and fixing effect of the packaging bag, preventing the packaging bag from falling, and playing the role of inverting the bag. A sealing strip is provided in the hopper. When the packaging bag is compressed, the door panel and the hopper side panel form an air cavity.

[0019] At the same time, considering that during the process of dust discharge upwards, since the air cavity is hollow, it is easy to be discharged outward along the air cavity, a cavity auxiliary mechanism is used. The air cavity auxiliary mechanism is installed on the outer wall of the hopper shell by bolts, and in the process of unloading, the exhaust fan is started to make the exhaust fan produce an extraction effect, so that when the generated dust is discharged into the cavity, it is quickly moved toward the cavity auxiliary mechanism due to the extraction effect.

[0020] It is also equipped with an activated carbon filter to filter dust, allowing the air flow to be discharged outwards, while the dust particles are stored separately due to the filtering effect of the activated carbon, further preventing the dust from being discharged outwards and affecting the working environment.

[0021] At the same time, taking into account the different sizes of dust particles generated in the process of packaging different granular materials, in order to further ensure the extraction efficiency of the exhaust fan and the filtering effect of the activated carbon filter, the device can first push the inner rod inward to separate the plug set on the outer wall of the inner rod from the inner wall of the card slot, and rotate the inner rod to make the inner rod drive the outer rod to rotate, so that the activated carbon filter plate is flipped during the rotation of the outer rod, so that one group of activated carbon filter plates on the inner wall of the outer shell is moved out, and the other group of activated carbon filter plates on the outside of the outer shell enters the inner wall of the outer shell, and the filter holes of the two groups of activated carbon filter plates are different in size, which is suitable for packaging and dust prevention of different granular materials, so that the activated carbon filter can be quickly replaced by rotation, so that different activated carbon filter plates can be used to ensure the filtering effect and improve the extraction efficiency.

[0022] At the same time, two groups of inclined panels are provided to seal the bottom of the shell, and the inclined surface of one group of inclined panels is at the top, while the inclined surface of the other group of inclined panels is at the bottom, to ensure the sealing effect during the extraction process of the shell, and cooperate with the extrusion plate provided on the activated carbon filter, so that the extrusion plate is driven to rotate simultaneously during the rotation of the activated carbon filter, so that the extrusion plate squeezes the inclined surface of the inclined panel, and the inclined panel moves outward due to the squeezing effect. By rotating the activated carbon filter, the two groups of inclined panels are automatically opened and closed, which ensures the sealing effect of the shell and makes the process of replacing the activated carbon filter more convenient and quicker.

[0023] The present invention provides a bag clamping hopper mechanism with an air chamber, which has the following beneficial effects:

[0024] 1. The present invention cooperates with the bag clamping door panels A and B in combination with the bag clamping pressure plate, and at the same time, sealing strips are arranged on the outer sides of the bag clamping door panels A and B, so that the sealing strips first contact with the packaging bag during the clamping process to prevent the middle of the bag opening from falling due to lack of clamping, thereby playing a role of covering the bag, so that when the material falls into the packaging bag, the bag opening is not only tightly clamped, but also sealed by an elastic member in the middle of the bag opening, thereby avoiding the generation of dust and the phenomenon of material rebound.

[0025] 2. The present invention first pushes the inner rod inward to separate the plug from the slot, and then rotates the inner rod to drive the outer rod and the activated carbon filter to rotate, thereby switching activated carbon filters with different filter hole sizes. Such a design is suitable for packaging and dust prevention of different granular materials, which can not only ensure the filtering effect, but also improve the extraction efficiency of the exhaust fan. This makes the bag clamping hopper mechanism have higher flexibility and adaptability when facing different packaging requirements, meeting the diversified packaging requirements of the chemical, fertilizer and other industries.

[0026] 3. While ensuring the dustproof effect, the present invention also pays attention to the convenience of operation. Two groups of inclined panels are provided to seal the bottom of the shell, and the inclined surface of one group of inclined panels is at the top, and the inclined surface of the other group of inclined panels is at the bottom, which ensures the sealing effect during the extraction process of the shell. At the same time, in conjunction with the extrusion plate on the activated carbon filter, during the rotation of the activated carbon filter, the extrusion plate squeezes the inclined surface of the inclined panel, so that the inclined panel automatically moves outward, and the two groups of inclined panels are automatically opened and closed by rotating the activated carbon filter. This design makes the process of replacing the activated carbon filter more convenient and faster, improves work efficiency, and reduces operation time and labor costs.
