Description

Technical Field

[0001] This application relates to the field of dry mortar packaging technology, and in particular to a bagged dry mortar packaging structure. Background Technology

[0002] Dry-mix mortar, also known as dry mortar powder, dry-mixed mortar, or dry-mixed powder, refers to a granular or powdery material made by physically mixing aggregates (such as quartz sand), inorganic cementitious materials (such as cement), and additives (such as polymers) in a certain proportion after drying and screening. It is transported to the construction site in bagged or bulk form and can be used directly after being mixed with water. Dry-mix mortar requires packaging structures when bagged and packaged.

[0003] In existing packaging structures, the packaging bag is usually placed on a platform, the discharge pipe of the packaging structure is inserted into the opening of the packaging bag, and then dry mortar is injected. Because there is a gap between the opening of the packaging bag and the discharge pipe, the packaging bag is prone to falling off the discharge pipe when the packaging machine injects dry mortar into the packaging bag. Therefore, an improvement is now made to a packaging structure for bagged dry mortar. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a bagged dry mortar packaging structure that overcomes the deficiencies of existing technologies. It aims to solve the problem that there is a gap between the discharge pipe of the existing packaging machine and the opening of the packaging bag, which makes the packaging bag easily fall off the discharge pipe when the packaging machine injects dry mortar into the packaging bag.

[0005] To achieve the above objectives, this application provides the following technical solution: a bagged dry powder mortar packaging structure, including a conveyor belt, a plurality of packaging machine frames fixedly installed on one side of the conveyor belt, a discharge pipe fixedly connected to the front side of each of the packaging machine frames, a positioning platform fixedly installed on the front side of the packaging machine frame below the discharge pipe, a cylinder two fixedly installed on the front side of the packaging machine frame between the discharge pipe and the positioning platform, a movable platform fixedly connected to the front end of the cylinder two, the movable platform being in contact with the positioning platform, an inner valve-mouth packaging bag placed on the upper surface of the movable platform, the inner valve-mouth packaging bag being fitted onto the outer wall of the discharge pipe, an extension arm fixedly installed on the front side of the packaging machine frame above the discharge pipe, a cylinder one fixedly installed on the lower surface of the extension arm, and an abutment block fixedly connected to the output end of the cylinder one.

[0006] By adopting the above technical solution, the inner valve packaging bag is placed on the moving platform, and the opening of the inner valve packaging bag is placed on the outer wall of the discharge pipe. The cylinder is activated to drive the abutment block to move downward, so that the inner valve packaging bag is pressed tightly against the outer wall of the discharge pipe, ensuring that the inner valve packaging bag will not detach from the discharge pipe during the subsequent filling process. After filling, the material inside the inner valve packaging bag will squeeze and seal the valve opening from the inside, thereby achieving automatic sealing. The cylinder is then driven to move the abutment block upward, so that the abutment block no longer abuts against the inner valve packaging bag. At this time, the cylinder pushes the moving platform outward, and the moving platform drives the inner valve packaging bag to move away from the discharge pipe to separate the two. Afterward, the inner valve packaging bag will slide off the moving platform onto the conveyor belt.

[0007] As a preferred technical solution of this application, the inner valve port packaging bag is located between the discharge pipe and the abutment block. The bottom of the abutment block is provided with a semi-circular groove, and the inner diameter of the semi-circular groove is adapted to the outer diameter of the discharge pipe. The inner wall of the semi-circular groove is provided with anti-slip texture.

[0008] By adopting the above technical solution, the cooperation between the semi-circular groove and the discharge pipe allows the inner valve opening packaging bag to be tightly abutted against the outer wall of the discharge pipe, ensuring that the inner valve opening packaging bag will not fall off. By setting anti-slip texture, the friction between the inner valve opening packaging bag and the abutting block is increased, further improving the clamping force of the abutting block.

[0009] As a preferred technical solution of this application, the front end of the discharge pipe is provided with a bevel, and the bevel direction of the bevel is set downward.

[0010] By adopting the above technical solution, the oblique cut design allows dry mortar to flow out more smoothly, which can prevent dry mortar from accumulating at the outlet and reduce residue on the pipe wall.

[0011] As a preferred technical solution of this application, the upper surface of the mobile platform is inclined, and a push plate is fixedly connected to the side of the upper surface of the mobile platform near the frame of the packaging machine.

[0012] By adopting the above technical solution, the moving platform applies an outward pushing force to the inner valve opening packaging bag through the push plate during the outward movement, which helps the inner valve opening packaging bag to detach from the discharge pipe. The inclined moving platform allows the inner valve opening packaging bag to slide off the moving platform under the action of gravity.

[0013] As a preferred technical solution of this application, the top of the positioning platform is provided with a sliding groove, and the bottom of the moving platform is fixedly connected with a slider that matches the sliding groove. The moving platform is slidably connected to the positioning platform through the slider.

[0014] By adopting the above technical solution, the slider is fixed at the bottom of the moving platform and embedded in the sliding groove at the top of the positioning platform to form a linear guide, so that the moving platform can move smoothly along the direction of the sliding groove.

[0015] As a preferred technical solution of this application, protective plates are symmetrically connected to both sides of the upper surface of the conveyor belt, and herringbone anti-slip texture is provided on the outer surface of the conveyor belt.

[0016] By adopting the above technical solution, the protective plate can not only limit and guide the inner valve packaging bag to prevent it from falling off the conveyor belt, but also protect the staff from accidentally stepping on the conveyor belt and falling. The herringbone anti-slip pattern increases the friction between the conveyor belt and the conveyed items, ensuring the stability and safety of the inner valve packaging bag during the transportation process.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this invention, the inner valve-mouth packaging bag is placed on a moving platform, and the opening of the inner valve-mouth packaging bag is fitted onto the outer wall of the discharge pipe. A cylinder is activated to drive the abutment block downwards, ensuring that the inner valve-mouth packaging bag is pressed tightly against the outer wall of the discharge pipe. This prevents the inner valve-mouth packaging bag from detaching from the discharge pipe during subsequent filling. After filling, the material inside the inner valve-mouth packaging bag is squeezed from the inside to seal the valve opening, thus achieving automatic sealing. The cylinder then drives the abutment block upwards, so that it no longer abuts against the inner valve-mouth packaging bag. At this point, a cylinder pushes the moving platform outwards, causing the inner valve-mouth packaging bag to move away from the discharge pipe, separating the two. The inner valve-mouth packaging bag then slides off the moving platform onto the conveyor belt.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 4 As shown, this embodiment provides a bagged dry powder mortar packaging structure, including a conveyor belt 1. Several packaging machine frames 2 are fixedly installed on one side of the conveyor belt 1. Each packaging machine frame 2 has a discharge pipe 4 fixedly connected to its front side. A positioning platform 9 is fixedly installed below the discharge pipe 4 on the front side of the packaging machine frame 2. A cylinder 10 is fixedly installed between the discharge pipe 4 and the positioning platform 9 on the front side of the packaging machine frame 2. A moving platform 11 is fixedly connected to the front end of the cylinder 10. The moving platform 11 is in contact with the positioning platform 9. An inner valve-mouth packaging bag 3 is placed on the upper surface of the moving platform 11, and the inner valve-mouth packaging bag 3 is fitted onto the outer wall of the discharge pipe 4. An extension arm 5 is fixedly installed above the discharge pipe 4 on the front side of the packaging machine frame 2. A cylinder 6 is fixedly installed on the lower surface of the extension arm 5. An abutment block 7 is fixedly connected to the output end of the cylinder 6. During use, the inner valve opening packaging bag 3 is placed on the moving table 11, and the opening of the inner valve opening packaging bag 3 is placed on the outer wall of the discharge pipe 4. The cylinder 6 is activated to drive the abutment block 7 to move downward, so that the inner valve opening packaging bag 3 is pressed against the outer wall of the discharge pipe 4 through the abutment block 7, ensuring that the inner valve opening packaging bag 3 will not detach from the discharge pipe 4 during the subsequent filling process. After the filling is completed, the material inside the inner valve opening packaging bag 3 will squeeze and close the valve opening from the inside, thereby achieving automatic sealing. The cylinder 6 drives the abutment block 7 to move upward, so that the abutment block 7 no longer abuts against the inner valve opening packaging bag 3. At this time, the cylinder 10 pushes the moving table 11 outward, and the moving table 11 drives the inner valve opening packaging bag 3 to move away from the discharge pipe 4 to separate the two. After that, the inner valve opening packaging bag 3 will slide off the moving table 11 onto the conveyor belt 1.

[0028] In this embodiment, as Figure 2 and 4As shown, the inner valve packaging bag 3 is located between the discharge pipe 4 and the abutment block 7. The bottom of the abutment block 7 is provided with a semi-circular groove 8, and the inner diameter of the semi-circular groove 8 is adapted to the outer diameter of the discharge pipe 4. The inner wall of the semi-circular groove 8 is provided with anti-slip texture. In use, through the cooperation between the semi-circular groove 8 and the discharge pipe 4, the inner valve packaging bag 3 can be tightly abutted against the outer wall of the discharge pipe 4, ensuring that the inner valve packaging bag 3 will not fall off. By setting the anti-slip texture, the friction between the inner valve packaging bag 3 and the abutment block 7 is increased, further improving the clamping force of the abutment block 7.

[0029] In this embodiment, as Figure 3 As shown, the front end of the discharge pipe 4 is provided with a bevel, and the bevel direction is set downward. During use, the bevel design allows the dry mortar to flow out more smoothly, which can prevent the dry mortar from accumulating at the outlet and reduce the residue on the pipe wall.

[0030] In this embodiment, as Figure 2 As shown, the upper surface of the moving platform 11 is inclined, and a push plate 12 is fixedly connected to the side of the upper surface of the moving platform 11 near the packaging machine frame 2. During use, the moving platform 11 applies an outward pushing force to the inner valve packaging bag 3 through the push plate 12 during outward movement, helping the inner valve packaging bag 3 to detach from the discharge pipe 4. The inclined moving platform 11 allows the inner valve packaging bag 3 to slide off the moving platform 11 under the action of gravity.

[0031] In this embodiment, as Figure 2 As shown, the top of the positioning platform 9 is provided with a sliding groove 13, and the bottom of the moving platform 11 is fixedly connected with a slider 14 that is adapted to the sliding groove 13. The moving platform 11 is slidably connected to the positioning platform 9 through the slider 14. In use, the slider 14 is fixed to the bottom of the moving platform 11 and embedded in the sliding groove 13 at the top of the positioning platform 9 to form a linear guide, so that the moving platform 11 can move smoothly along the direction of the sliding groove 13.

[0032] In this embodiment, as Figure 1 As shown, protective plates 16 are symmetrically connected to both sides of the upper surface of the conveyor belt 1. The outer surface of the conveyor belt 1 is provided with herringbone anti-slip texture 15. During use, the protective plates 16 can not only limit and guide the inner valve packaging bag 3 to prevent it from falling off the conveyor belt 1, but also protect the staff to prevent them from accidentally stepping on the conveyor belt 1 and falling. The herringbone anti-slip texture 15 increases the friction between the conveyor belt 1 and the conveyed items, ensuring the stability and safety of the inner valve packaging bag 3 during the conveying process.

[0033] The working principle of this utility model is as follows: When using the bagged dry powder mortar packaging structure of this application, the worker first places the inner valve opening packaging bag 3 on the moving table 11 and covers the bag opening of the inner valve opening packaging bag 3 on the outer wall of the discharge pipe 4. Then, the cylinder 6 is activated to drive the abutment block 7 to move downward, so that the abutment block 7 presses the inner valve opening packaging bag 3 against the outer wall of the discharge pipe 4, ensuring that the inner valve opening packaging bag 3 will not detach from the discharge pipe 4 during the subsequent filling process. After filling, the material inside the inner valve opening packaging bag 3 will squeeze and seal the valve opening from the inside, thereby achieving automatic sealing. The cylinder 6 is activated to drive the abutment block 7 to move upward, so that the abutment block 7 no longer abuts the inner valve opening packaging bag 3. At this time, the cylinder 10 is activated to push the moving table 11 outward. The moving table 11 drives the inner valve opening packaging bag 3 to move away from the discharge pipe 4, so that the two are separated. Then, the inner valve opening packaging bag 3 will slide off the moving table 11 onto the conveyor belt 1 under the action of gravity.
