Description

Technical Field

[0001] This utility model relates to the field of plaster production technology, specifically to a feeding mechanism for the production of lightweight plaster. Background Technology

[0002] Plastering gypsum, also known as plastering plaster, is a plastering material for the interior walls and ceilings of buildings. It is made from gypsum cementitious materials as a base. Specifically, it is made from calcium sulfate dihydrate through dehydration or anhydrous calcium sulfate through calcination and / or activation. The products are calcium sulfate hemihydrate and type II anhydrous calcium sulfate, either alone or in combination with additives. Aggregates can also be added to make the plastering material.

[0003] A search revealed an existing patent (publication number: CN 217597455 U) disclosing a quantitative feeding mechanism for lightweight plaster, relating to the field of feeding equipment technology. The mechanism includes a base plate, a filtering and screening unit, and a quantitative feeding unit. The base plate is rectangular. The filtering and screening unit comprises rectangular support columns, sliding columns, springs, a connecting plate, a motor, a semi-circular weight, a motor support plate, a slider, a screening box, and filter holes. The two ends of the upper surface of one end of the base plate are fixedly connected to the lower ends of two corresponding rectangular support columns. The upper ends of the two rectangular support columns are fixedly connected to the lower ends of two sliding columns, and the upper ends of the two sliding columns are fixedly connected to the two ends of the lower surface of the connecting plate. This mechanism can filter and screen plaster, thereby preventing lumpy particles in the plaster from entering the mixing equipment and preventing particles in the mortar from causing unevenness on the plastered wall surface, resulting in a better plastering effect.

[0004] However, in the above scheme, after the equipment completes the screening, the unscreened plaster needs to be manually processed, and the screening plate used for screening will accumulate a lot of dust on its surface after long-term use, making it impossible to disassemble for cleaning.

[0005] In view of this, the present invention proposes a feeding mechanism for the production of lightweight plaster. Utility Model Content

[0006] This utility model proposes a feeding mechanism for the production of lightweight plaster, which solves the problems of the need for manual processing of unscreened plaster after screening in related technical equipment, and the problem that the screening plate will accumulate a lot of dust on its surface after long-term use and cannot be disassembled for cleaning.

[0007] The technical solution of this utility model is as follows: A feeding mechanism for the production of lightweight plaster includes a base, a side plate fixedly connected to the top of the base, a first servo motor fixedly connected to the base at one end of the side plate, a turntable fixedly connected to the output end of the first servo motor, a push plate fixedly connected to the top of the turntable, a slider slidably connected inside the side plate, a force plate fixedly connected to the bottom of the slider, a first spring fixedly connected to the side plate on both sides of the slider, a screening chamber fixedly connected to one end of the slider, a baffle fixedly connected inside the screening chamber, a filter plate attached to the bottom of the baffle, a positive and negative lead screw rotatably connected to the surface of the screening chamber, and two sets of fixing blocks slidably connected to the screening chamber and attached to the bottom of the filter plate connected to the surface of the positive and negative lead screw.

[0008] Preferably, a screw is threadedly connected to the inside of the screening chamber, and a second servo motor with its output end fixedly connected to the screw is fixedly connected to the outer wall of the screening chamber. A movable plate that is slidably connected to the screening chamber is threadedly connected to the surface of the screw. A push rod is fixedly connected to the right side of the movable plate, and a connecting plate is fixedly connected to the right side wall of the screening chamber. A limit rod is fixedly connected inside the connecting plate, and a closing plate is fixedly connected to one side of the limit rod. A second spring that is fixedly connected to the connecting plate is fixedly connected to one side of the closing plate. A transmission belt located at the top of the base is provided below the screening chamber.

[0009] Preferably, the force plate is perpendicular to the slider, and the force plate is located on the motion trajectory of the push plate.

[0010] Preferably, the slider and the side plate are in a close fit, and the slider compresses the first spring through the force plate.

[0011] Preferably, the filter plate is fixed by fixing blocks, and the two sets of fixing blocks are connected by positive and negative lead screws to form a reverse sliding structure.

[0012] Preferably, both the moving plate and the closing plate are flush with the inner wall of the screening chamber, and the moving plate and the closing plate form a closed state on both sides of the screening chamber.

[0013] Preferably, the sealing plate is located on the movement trajectory of the push rod, and the limiting rod forms a sliding structure inside the connecting plate through the push rod.

[0014] Preferably, the transmission belt coincides with the central axis of the screening chamber.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, a push plate is set up. When the push plate rotates, it pushes the force plate, causing the force plate to slide along the inside of the side plate and squeeze the first spring. When the push plate disengages from the force plate, the first spring drives the slider back to the initial position. When the push plate rotates back and forth, it cooperates with the first spring to drive the screening chamber to sway left and right, thereby screening the plaster through the filter plate. At this time, the fine plaster will pass through the filter plate and fall onto the transmission belt to be transported to the processing area, realizing the feeding operation. When it is necessary to remove the filter plate to clean the dust on its surface, the positive and negative screws can be rotated to control the two sets of fixed blocks to slide in opposite directions and disengage from the bottom of the filter plate. At this time, the filter plate can be removed.

[0017] 2. In this utility model, by setting a moving plate, after the plaster is screened, the second servo motor can be turned on to control the screw to rotate. When the screw rotates, it will drive the moving plate to move along the inside of the screening chamber. Finally, during the movement, some plaster that has not been screened down will be pushed to the right along the filter plate. Finally, the push rod will push open the closed plate and push the plaster onto the transmission belt for transport. When the push rod moves to the left, the closed plate will return to the initial position under the action of the second spring. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] A preferred embodiment of the feeding mechanism for producing lightweight plastering gypsum provided by this utility model is as follows: Figures 1 to 5 As shown: A feeding mechanism for the production of lightweight plaster includes a base 1, a side plate 2 fixedly connected to the top of the base 1, a first servo motor 3 fixedly connected to the base 1 at one end of the side plate 2, a turntable 4 fixedly connected to the output end of the first servo motor 3, a push plate 5 fixedly connected to the top of the turntable 4, a slider 7 slidably connected inside the side plate 2, a force plate 6 fixedly connected to the bottom of the slider 7, a first spring 8 fixedly connected to the side plate 2 on both sides of the slider 7, a screening chamber 9 fixedly connected to one end of the slider 7, a baffle 10 fixedly connected inside the screening chamber 9, a filter plate 11 attached to the bottom of the baffle 10, a positive and negative lead screw 12 rotatably connected to the surface of the screening chamber 9, and two sets of fixing blocks 13 threadedly connected to the screening chamber 9 and attached to the bottom of the filter plate 11.

[0028] In this embodiment, the force plate 6 and the slider 7 are perpendicular to each other. The force plate 6 is located on the motion trajectory of the push plate 5. The first servo motor 3 is turned on to control the turntable 4 to rotate. The push plate 5 rotates accordingly and pushes the force plate 6 during rotation, causing the force plate 6 to drive the slider 7 to slide along the inside of the side plate 2 and squeeze the first spring 8.

[0029] In this embodiment, the slider 7 and the side plate 2 are in a close fit. The slider 7 is compressed by the force plate 6 against the first spring 8. When the push plate 5 is separated from the force plate 6, the first spring 8 drives the slider 7 back to the initial position. When the push plate 5 rotates back and forth, it will cooperate with the first spring 8 to drive the screening chamber 9 to sway left and right, so as to screen the plaster gypsum through the filter plate 11.

[0030] In this embodiment, the filter plate 11 is fixed by the fixing block 13. The two sets of fixing blocks 13 are connected by the positive and negative screws 12 to form a reverse sliding structure. When the filter plate 11 needs to be removed to clean the dust on its surface, the positive and negative screws 12 can be rotated to control the two sets of fixing blocks 13 to slide in opposite directions and disengage from the bottom of the filter plate 11. At this time, the filter plate 11 can be removed.

[0031] Example 2

[0032] Based on Example 1, a preferred embodiment of the feeding mechanism for producing lightweight plastering gypsum provided by this utility model is as follows: Figures 1 to 5 As shown: a screw 14 is threadedly connected to the inside of the screening chamber 9. A second servo motor 22 with its output end fixedly connected to the screw 14 is fixedly connected to the outer wall of the screening chamber 9. A moving plate 15 that is slidably connected to the screening chamber 9 is threadedly connected to the surface of the screw 14. A push rod 16 is fixedly connected to the right side of the moving plate 15. A connecting plate 17 is fixedly connected to the right side wall of the screening chamber 9. A limit rod 19 is fixedly connected inside the connecting plate 17. A closing plate 18 is fixedly connected to one side of the limit rod 19. A second spring 20 that is fixedly connected to the connecting plate 17 is fixedly connected to one side of the closing plate 18. A transmission belt 21 located at the top of the base 1 is provided below the screening chamber 9.

[0033] In this embodiment, both the moving plate 15 and the closing plate 18 are flush with the inner wall of the screening chamber 9. The moving plate 15 and the closing plate 18 form a closed state on both sides of the screening chamber 9. Closing the two sides of the screening chamber 9 can prevent plaster from falling out of the screening chamber 9 during screening.

[0034] In this embodiment, the closed plate 18 is located on the movement trajectory of the push rod 16, and the limiting rod 19 forms a sliding structure inside the connecting plate 17 through the push rod 16. When the screw 14 rotates, it will drive the moving plate 15 to move along the inside of the screening chamber 9. Finally, during the movement, some plaster that has not been screened down will be pushed to the right along the filter plate 11. Eventually, the closed plate 18 will be pushed open by the push rod 16, and the plaster will be pushed onto the transmission belt 21 for transport.

[0035] In this embodiment, the central axis of the transmission belt 21 coincides with that of the screening chamber 9, so that the plaster that is pushed off can fall precisely onto the transmission belt 21.

[0036] The working principle and usage process of this utility model are as follows: First, when feeding is required, the material can be poured into the screening chamber 9. Then, the first servo motor 3 is turned on to control the turntable 4 to rotate, and the push plate 5 rotates accordingly. During rotation, it pushes the force plate 6, causing the force plate 6 to drive the slider 7 to slide along the inside of the side plate 2 and squeeze the first spring 8. When the push plate 5 disengages from the force plate 6, the first spring 8 drives the slider 7 back to the initial position. When the push plate 5 rotates back and forth, it will cooperate with the first spring 8 to drive the screening chamber 9 to sway left and right, thereby screening the plaster through the filter plate 11. At this time, the fine plaster will pass through the filter plate 11 and fall onto the transmission belt 21 to be transported to the processing area, thus realizing the feeding operation. When it is necessary to remove the filter plate 11 to clean the dust on its surface, the positive and negative screws 12 can be rotated to control the two sets of fixed blocks 13 to slide in opposite directions and disengage from the bottom of the filter plate 11. At this time, the filter plate 11 can be removed.

[0037] After the plaster is sieved, the second servo motor 22 can be turned on to control the screw 14 to rotate. When the screw 14 rotates, it will drive the moving plate 15 to move along the inside of the sieve chamber 9. Finally, during the movement, some plaster that has not been sieved will be pushed to the right along the filter plate 11. Eventually, the push rod 16 will push open the closing plate 18 and push the plaster onto the transmission belt 21 for transport. When the push rod 16 moves to the left, the closing plate 18 will return to the initial position under the action of the second spring 20.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
