Description

Technical Field

[0001] This utility model belongs to the field of mortar packaging technology, specifically an environmentally friendly filling equipment for dry-mixed mortar production. Background Technology

[0002] Mortar packaging machines are widely used in the production and packaging of dry mortar. Their automated operation can save a lot of manual labor and greatly improve work efficiency.

[0003] In practical use, the applicant found that valve bags are currently commonly used for packaging dry mortar. During filling, the valve opening of the valve bag is inserted into the discharge pipe of the mortar packaging machine, and then the clamping devices on both sides are used to help position the valve bag to prevent it from deviating and powder from overflowing during filling. However, since the valve bag opening is generally cylindrical, some powder may still overflow from the un-clamped part if only the clamping device is used for sealing. This not only pollutes the working environment but also wastes the dry mortar, which is not environmentally friendly. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly filling equipment for dry-mixed mortar production in order to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: An environmentally friendly dry-mixed mortar production filling equipment includes a mortar filling machine. The filling machine has a discharge pipe for discharging material arranged horizontally along its upper side. The outer circumferential surface of the discharge pipe is provided with a sealing structure. The sealing structure includes a convex ring, an air bladder, and an air supply component for venting and / or drawing air into the air bladder. The convex ring and the discharge pipe together form a bag mouth receiving cavity with an opening on one side. The air bladder has an annular structure and is located in the bag mouth receiving cavity. When an external valve bag is fitted into the bag mouth receiving cavity, the air supply component supplies air to the air bladder so that the air bladder expands and fits tightly against the bag mouth of the valve bag.

[0006] In a preferred embodiment, the inner wall of the convex ring is recessed in the circumferential direction to form an annular groove, and the airbag is embedded in the annular groove. When the airbag is in an inflated state, the airbag part extends out of the annular groove.

[0007] In a preferred embodiment, a proximity switch is embedded in the inner wall of the convex ring on the side of the airbag facing the mortar filling machine.

[0008] In a preferred embodiment, a vacuum cleaner with a dust collection bin is provided directly above the discharge pipe, and the vacuum cleaner has a dust suction hood facing the discharge pipe in the suction direction.

[0009] In a preferred embodiment, the filling machine is equipped with a PLC terminal, and the proximity switch and the air supply component are both controlled by the PLC terminal.

[0010] In a preferred embodiment, the air supply assembly includes an air pump, a solenoid valve, and an air pipe arranged in sequence, with one end of the air pipe connected to the airbag.

[0011] In a preferred embodiment, the air pump is a blower-suction air pump.

[0012] In a preferred embodiment, a support platform is provided directly below the discharge pipe, and a weighing sensor is provided on the support platform. The support platform is mounted on the filling machine via a support frame.

[0013] In a preferred embodiment, the end of the discharge pipe has a downwardly sloping tip.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: Using an annular airbag as the clamping structure for the valve bag opening, the airbag is inflated when the valve bag opening is inserted into the bag opening receiving cavity. The expanded airbag adheres tightly to the valve bag opening. Utilizing the cooperation of the airbag and the discharge pipe, the valve bag opening is clamped and sealed in all directions, preventing powder overflow. This saves materials while ensuring a good working environment, possessing advantages not currently available in other products. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] Reference Figure 1-3An environmentally friendly dry-mixed mortar production filling equipment includes a mortar filling machine 1. A discharge pipe 10 for discharging material is arranged laterally on the filling machine 1. A sealing structure is provided on the outer circumference of the tail end of the discharge pipe 10. The sealing structure includes a convex ring 13, an air bladder 12, and an air supply component for venting and / or drawing air into the air bladder 12. The convex ring 13 and the discharge pipe 10 together form a bag mouth receiving cavity 14 with an opening on one side. The air bladder 12 has an annular structure and is located within the bag mouth receiving cavity 14. When the external valve bag is fitted into the bag mouth receiving cavity 14, the air supply component... The airbag 12 is supplied with air to inflate it and make it fit tightly against the valve bag opening. The annular airbag 12 serves as the clamping structure for the valve bag opening. When the valve bag opening is inserted into the bag opening receiving cavity 14, the air supply component inflates the airbag 12. The expanded airbag 12 fits tightly against the valve bag opening. By cooperating with the airbag 12 and the discharge pipe 10, the valve bag opening is clamped and sealed in all directions. This provides a better fixing effect and prevents powder overflow. It saves materials and ensures a good working environment.

[0021] Among them, the mortar filling machine 1 is a commonly used and well-known piece of equipment in the existing technology. Its specific structure will not be described in detail here. It mainly includes the machine body, feeding structure (using screw or impeller feeding), etc.

[0022] Furthermore, the inner wall of the convex ring 13 is recessed in the circumferential direction to form an annular groove, and the airbag 12 is embedded in the annular groove. When the airbag 12 is in an inflated state, the airbag 12 extends out of the annular groove. When the airbag 12 is in the initial (i.e. uninflated) state, the airbag 12 retracts into the annular groove, so that the normal loading and unloading operation of the valve bag will not be affected when loading and unloading the valve bag.

[0023] Furthermore, a proximity switch 11 is embedded in the inner wall of the convex ring 13 on the side of the airbag 12 facing the mortar filling machine 1. The filling machine 1 is equipped with a PLC terminal 9. The proximity switch 11 and the air supply component are both controlled by the PLC terminal 9. When the valve bag is filled into the bag opening cavity 14, the proximity switch 11 receives the bag opening signal, and the air supply component automatically inflates the airbag 12 without manual operation. When the designed weight is reached, the air supply component automatically extracts the gas inside the airbag 12, which is convenient for operators.

[0024] Furthermore, a vacuum cleaner 2 with a dust collection bin is installed directly above the discharge pipe 10. The vacuum cleaner 2 has a dust collection hood 3 facing the discharge pipe 10. Through the cooperation of the vacuum cleaner 2 and the dust collection hood 3, dust that may be generated in the working environment (such as a small amount of dust that may overflow when the valve bag is removed) can be sucked away to ensure a good working environment. The vacuum cleaner is a commonly used device in the prior art. The specific structure will not be described here. It includes the vacuum cleaner body and a detachable dust collection bin.

[0025] Furthermore, the air supply assembly includes an air pump 8, a solenoid valve (not shown in the figure), and an air pipe 7 arranged in sequence. One end of the air pipe 7 is connected to the airbag 12. The air pump 8 is a blow-and-suction air pump, which can simultaneously supply air to and depress the airbag 12 to meet the expansion and contraction operations of the airbag 12. The preferred model of the air pump 8 is XGB-9B, but it is not limited here.

[0026] Furthermore, a support platform 5 is provided directly below the discharge pipe 10, and a weighing sensor 4 is provided on the support platform 5. The support platform 5 is installed on the filling machine 1 through the support frame 6. The weighing sensor 4 can weigh the filling material. When the detected weight reaches the weight set at the PLC terminal 9, the feeding structure of the filling machine 1 automatically stops feeding, which can realize quantitative filling operation. The weighing sensor 4 is electrically connected to the PLC terminal 9.

[0027] Reference Figure 1 As shown, the end of the discharge pipe 10 has a downward-sloping beveled tip, which facilitates the insertion of the valve bag opening.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
