Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for a dry-mix mortar machine, in particular to a quantitative conveying mechanism for a dry-mix mortar machine. Background Art

[0002] Dry-mix mortar is one of the emerging dry-mix materials in the field of building materials. It is a mixture of cement as the main binder and dry-screened fine aggregate, mineral admixtures, reinforcing materials and admixtures in a certain proportion. It is transported to the construction site in bags or bulk. It can be used directly after adding water and mixing. It is also called mortar dry powder, dry mix, and dry mix powder. Some building adhesives also belong to this category. Dry-mix mortar plays a bonding, cushioning, protective and decorative role in the construction industry with a thin layer. It is widely used in construction and decoration projects. In order to meet different usage needs, dry-mix mortar machines are transported in bulk or bags during transportation. Usually, the packaging bag is manually placed on the discharge port, and then the valve is opened to inject the material, and then the bag is sealed and packaged. This packaging method usually determines the weight according to the size of the bag. Therefore, the weight of each bag varies.

[0003] For example, a quantitative conveying mechanism for a dry-mix mortar machine disclosed in a Chinese patent document (Announcement No.: CN219361388U) enters the containing frame through a connecting pipe, drives the containing frame and the No. 2 telescopic rod to move down and contact the trigger, and the electric push rod pushes the fixed plate and the No. 1 telescopic rod to stretch, and the containing frame tilts. The raw materials in the containing frame are poured out from the baffle onto the conveying assembly, so that the mortar raw materials can be accurately and quantitatively discharged, avoiding uneven weight. However, after each weighing, the material needs to be poured onto the conveying assembly first, and then bagged through conveying. The operation is cumbersome, the bagging efficiency is low, and the trigger cannot be adjusted, resulting in the problem of being unable to quantitatively load materials of different weights according to usage needs.

[0022] Furthermore, the tooth surface of the gear 7 meshes with the tooth surface of the rack 4, and the upper surface of the rotating block 6 is provided with symmetrically distributed placement grooves 71. A servo electric cylinder 72 is fixedly installed on the inner wall of one side of the movable base 1. The rack 4 moves stably through the cooperation of the guide rod 3. The reciprocating movement of the rack 4 drives the rotating rod 5 and the rotating block 6 to rotate reciprocatingly through the meshing gear 7.

[0023] Furthermore, one end of the piston rod of the servo electric cylinder 72 is fixedly connected to a connecting block 73, the back side of the connecting block 73 is fixedly connected to the front side of the rack 4, and the upper surface of the movable base 1 is fixedly connected to a fixed bracket 74. The telescopic movement of the piston rod of the servo electric cylinder 72 drives the rack 4 to perform reciprocating motion through the connecting block 73.

[0024] Furthermore, a storage sleeve 75 is fixedly sleeved on the inner wall of the fixed bracket 74, a first discharge pipe 76 is fixedly connected to the lower surface of the storage sleeve 75, a first solenoid valve 77 is fixedly installed on the outer surface of the first discharge pipe 76, and a limiting rod 78 distributed in a ring array is fixedly connected to the upper surface of the fixed bracket 74, and the fixed bracket 74 serves to fix and support the storage sleeve 75.

[0025] Furthermore, the outer surfaces of the plurality of limit rods 78 are movably connected with an annular lifting block 79, and the outer surfaces of the limit rods 78 are movably connected with a support spring 710. One ends of the plurality of support springs 710 are fixedly connected to the lower surface of the annular lifting block 79, and the other ends of the plurality of support springs 710 are fixedly connected to the upper surface of the fixed bracket 74. The elastic force of the support spring 710 drives the annular lifting block 79 to reset and move through the cooperation of the limit rod 78.

[0026] Furthermore, a metering sleeve 711 is fixedly sleeved on the inner wall of the annular lifting block 79, a second discharge pipe 712 is fixedly connected to the lower surface of the metering sleeve 711, a second solenoid valve 713 is fixedly installed on the outer surface of the second discharge pipe 712, and a threaded block 714 is fixedly connected to the outer surface of the annular lifting block 79. Addition of material in the metering sleeve 711 will drive the annular lifting block 79 to move downward.

[0027] Furthermore, a screw rod 715 is threadedly connected to the inner wall of the threaded block 714, a mounting block 716 is installed on the outer surface of one end of the screw rod 715 through a bearing, a contact switch 717 is fixedly installed on the lower surface of the mounting block 716, a vertical rod 718 is fixedly connected to the upper surface of the mounting block 716, one end of the vertical rod 718 penetrates and extends to the upper surface of the threaded block 714, and the other end of the screw rod 715 is fixedly connected to a driving handle, which can be started to drive the screw rod 715 to rotate and adjust.

[0028] The quantitative packaging device can realize automatic weighing of dry-mixed mortar, thereby avoiding uneven weight of bags. The height of the contact switch 717 can be adjusted to make it suitable for packaging of different weights, thereby improving practicality. The rotation of the rotating block 6 can realize synchronous operation of packaging and discharging, thereby improving the packaging efficiency.

[0029] Working principle: Step 1, the mobile base 1 is moved by moving the self-locking universal wheel 2, and the metering sleeve 711 is moved to the bottom of the mortar machine. Then, two packaging bags are placed in the two placement slots 71 respectively, and then the material can be discharged. The addition of materials causes the metering sleeve 711 to squeeze the support spring 710 through the annular lifting block 79, and the annular lifting block 79 drives the metering sleeve 711 to move downward. When the contact switch 717 moves to contact the top of the fixed bracket 74, the mortar machine stops discharging, and the second solenoid valve 713 is opened, and the material in the metering sleeve 711 enters the storage sleeve 75 through the second discharge pipe 712;

[0030] Step 2: After the second discharge pipe 712 has finished discharging, the second solenoid valve 713 is closed, and the mortar machine continues to discharge. At the same time, the first solenoid valve 77 is opened, and the material is discharged and packaged to the packaging bag in the placement groove 71 through the first discharge pipe 76. When the packaging is completed, the first solenoid valve 77 is closed, and the piston rod of the servo electric cylinder 72 is started to extend, and the rack 4 is driven to move through the connecting block 73. The movement of the rack 4 drives the rotating rod 5 to rotate through the meshing gear 7. The rotation of the rotating rod 5 drives the rotating block 6 to rotate 180 degrees, so that another empty bag is rotated to the bottom of the first discharge pipe 76;

[0031] Step three, at this time the staff will remove the packaged dry mortar and place a new empty bag. At the same time, the quantitative sleeve 711 continues to discharge the storage sleeve 75 through the second discharge pipe 712 after the contact switch 717 moves to contact the fixed bracket 74, and the cycle continues like this. The staff can rotate the screw 715 clockwise to drive the mounting block 716 to move downward through the limit of the vertical rod 718, thereby reducing the amount of sand inside the quantitative sleeve 711. Conversely, rotating the screw 715 counterclockwise will increase the amount of sand inside the quantitative sleeve 711, thereby achieving adjustment according to usage requirements.
