Description

Technical Field

[0001] The present application relates to the technical field of mixer discharge doors, and in particular to a mixer discharge door with a self-locking function. Background Art

[0002] Mixers are commonly used equipment in industrial production, used to evenly mix multiple materials. The mixer discharge door is an important component of the mixer, responsible for discharging the materials from the mixer after mixing. The discharge door is usually designed as a rotatable or sliding door panel, and its opening and closing are controlled by mechanical or pneumatic means. Its structure and performance directly affect the mixing efficiency and material discharge efficiency.

[0003] Existing mixer discharge doors are mostly pneumatically or electrically driven, and the door panels are opened and closed by control signals. During operation, when the discharge door is closed, the material is locked inside the mixer to prevent leakage.

[0004] Although the existing discharge door design can meet the usage requirements in most cases, in some cases, due to the gravity of the material and the pressure inside the mixer, the discharge door may be accidentally opened in the closed state, causing material leakage. Especially when the material is accumulated or the pressure inside the mixer is high, the discharge door does not have a certain self-locking property and may not be sufficient to resist these external forces, thereby causing leakage problems. For this reason, the present application provides a mixer discharge door with a self-locking function. Utility Model Content

[0005] The purpose of this application is to solve the problem that the discharge door may be accidentally opened in a closed state due to the gravity of the material and the pressure inside the mixer, resulting in material leakage. This application provides a mixer discharge door with a self-locking function.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A mixer unloading door with a self-locking function comprises a mixer body, wherein the interior of the mixer body is symmetrically connected to two rotating shafts, two support plates are symmetrically fixedly connected to the two rotating shafts, and the ends of the two support plates away from the rotating shafts are fixedly connected to the unloading door body, the unloading door body is fitted with the discharge port at the bottom of the mixer body, two drive assemblies are symmetrically installed on one side of the mixer body, and two limit assemblies are symmetrically installed on one side of the discharge port of the mixer body.

[0008] By adopting the above technical solution, the driving component is first started to drive the rotating shaft to rotate, so as to drive the discharge door body to fit tightly with the discharge port at the bottom of the mixer body through the support plate. After the discharge door body fits with the discharge port, the limiting component can be started to operate. The position of the discharge door body after closing can be limited by the limiting component, so that the discharge door body can always fit with the discharge port and remain in a closed state, preventing material leakage or accidental discharge, thereby reducing material waste, improving production efficiency, and reducing safety risks in the workplace.

[0009] Furthermore, the drive assembly includes two cylinders symmetrically hinged on one side of the mixer body, the output ends of the two cylinders are hinged with a connecting block, one end of the connecting block is hinged with a connecting rod 1, one end of the two rotating shafts is fixedly connected to a connecting plate, and the end of the connecting plate away from the rotating shaft is fixedly connected to one end of the connecting rod 1.

[0010] By adopting the above technical solution, the cylinder is started to push the connecting block to move. At this time, the rotation of the connecting rod 1 will drive the connecting plate to drive the rotating shaft to rotate, thereby driving the discharge door body through the support plate to fit tightly with the discharge port at the bottom of the mixer body.

[0011] Furthermore, the end of the connecting block away from the connecting rod 1 is hinged with the connecting rod 2, one side of the mixer body is fixedly connected with a fixed plate, and the end of the connecting rod 2 away from the connecting block is rotatably connected to one end of the fixed plate.

[0012] By adopting the above technical solution, when the unloading door body is closed and the equipment malfunctions, causing the cylinder and the limit assembly to fail to operate, at this time, since the connecting block, connecting rod 1 and connecting rod 2 are in the same horizontal straight line, the fixing plate can play a role of limiting the collision between the connecting block, connecting rod 1 and connecting rod 2, thereby preventing the rotating shaft from rotating.

[0013] Furthermore, the limiting assembly includes a fixed block symmetrically fixedly connected to one side of the mixer body discharge port, the internal rotation of the fixed block is connected to a screw rod, one end of the fixed block is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to one end of the screw rod, an adjustment block is threadedly connected to the screw rod, a slot is provided on one side of the discharge door body, the shape and size of the slot are consistent with one end of the adjustment block, and a clamping piece is provided at one end of the adjustment block.

[0014] By adopting the above technical solution, the servo motor is started to drive the adjustment block to move, so that one end of the adjustment block gradually enters the interior of the slot, limiting the position of the discharge door body after closing.

[0015] Furthermore, both ends of the adjusting block are fixedly connected with T-shaped blocks, and both sides of the fixed block are provided with sliding grooves, and the T-shaped blocks are slidably connected in the sliding grooves.

[0017] Furthermore, the clamping part includes grooves symmetrically opened on both sides of one end of the adjustment block, the interior of the grooves is fixedly connected to a spring, the interior of the grooves is slidably connected to a clamping block, one end of the clamping block is fixedly connected to one end of the spring, and limiting grooves are opened on both sides of the interior of the clamping groove.

[0018] By adopting the above technical solution, when one end of the adjusting block is fully inserted into the slot, one end of the block is squeezed into the limit slot according to the rebound of the spring, so that the position of the discharge door body is locked again through the mutual cooperation between the block and the limit slot.

[0019] Furthermore, the end of the clamping block away from the spring is arc-shaped, and the shape and size of the limiting groove are consistent with the arc-shaped end of the clamping block.

[0020] By adopting the above technical solution, one end of the adjusting block enters the card slot, and the inner wall of the card slot squeezes the arc-shaped end of the card block, making it convenient to squeeze it into the inside of the groove.

[0021] Furthermore, a sealing plate is fixedly connected to the top of the discharge door body.

[0022] By adopting the above technical solution, the sealing plate provided can effectively improve the sealing between the discharge door body and the discharge port, preventing material leakage or accidental discharge, thereby reducing material waste.

[0024] 1. This application provides a limit assembly and a clamping piece. When the discharge door body is fitted against the discharge port, the limit assembly can be started to operate. The position of the discharge door body after closing can be limited by the limit assembly and the clamping piece, so that the discharge door body can always fit against the discharge port and remain in a closed state, preventing material leakage or accidental discharge, thereby reducing material waste, improving production efficiency, and reducing safety risks in the workplace. At the same time, it can also prevent the discharge door body from accidentally opening due to material pressure or gravity, reducing damage to the discharge door body.

[0025] 2. The present application is provided with a driving assembly. If, after the discharge door body is closed, an abnormality occurs in the equipment, causing the cylinder and the limit assembly to fail to operate, at this time, since the connecting block, connecting rod 1 and connecting rod 2 are in the same horizontal straight line, the fixing plate can limit the interference between the connecting block, connecting rod 1 and connecting rod 2, thereby preventing the rotating shaft from rotating. In this way, the discharge door body can still maintain a certain degree of support and self-locking in the event of an abnormality in the equipment, thereby greatly reducing the risk of material leakage.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1 —4 provides further details of this application.

[0033] The embodiment of the present application discloses a mixer discharge door with a self-locking function.

[0034] Reference Figure 1 and Figure 2 A mixer unloading door with a self-locking function comprises a mixer body 1, wherein the interior of the mixer body 1 is symmetrically connected to two rotating shafts 2, two support plates 3 are symmetrically fixedly connected to the two rotating shafts 2, and the ends of the two support plates 3 away from the rotating shafts 2 are fixedly connected to a unloading door body 4, and the unloading door body 4 is fitted with the discharge port at the bottom of the mixer body 1, two driving assemblies are symmetrically installed on one side of the mixer body 1, and two limit assemblies are symmetrically installed on one side of the discharge port of the mixer body 1;

[0035] Secondly, the driving assembly includes two cylinders 5 symmetrically hinged on one side of the mixer body 1, the output ends of the two cylinders 5 are hinged with a connecting block 6, one end of the connecting block 6 is hinged with a connecting rod 1 7, one end of the two rotating shafts 2 is fixedly connected with a connecting plate 8, the end of the connecting plate 8 away from the rotating shaft 2 is fixedly connected to one end of the connecting rod 1 7, the end of the connecting block 6 away from the connecting rod 1 7 is hinged with a connecting rod 2 9, one side of the mixer body 1 is fixedly connected with a fixed plate 10, and the end of the connecting rod 2 9 away from the connecting block 6 is rotatably connected to one end of the fixed plate 10.

[0036] When in use, first start the cylinder 5 to drive the connecting block 6 to move, thereby driving the connecting rod 1 7 to rotate through the movement of the connecting block 6. As the connecting block 6 gradually moves, the connecting block 6, the connecting rod 1 7 and the connecting rod 2 9 will be in the same straight line. At this time, the rotation guidance of the connecting rod 1 7 will drive the connecting plate 8 to drive the rotating shaft 2 to rotate, thereby driving the discharge door body 4 to fit tightly with the discharge port at the bottom of the mixer body 1 through the support plate 3. After the discharge door body 4 fits the discharge port, the limit assembly can be started to operate. The limit assembly can limit the position of the discharge door body 4 after closing, so that the discharge door body 4 can always fit with the discharge port and remain closed to prevent material leakage. Or accidentally discharged, thereby reducing material waste, improving production efficiency, reducing safety risks in the workplace, and at the same time preventing the discharge door body 4 from accidentally opening due to material pressure or gravity, thereby reducing damage to the discharge door body 4. In addition, in daily use, if after the discharge door body 4 is closed, the equipment malfunctions and the cylinder 5 and the limit assembly cannot operate, at this time, because the connecting block 6, connecting rod 1 7 and connecting rod 2 9 are in the same horizontal straight line, the fixing plate 10 can limit the collision of the connecting block 6, connecting rod 1 7 and connecting rod 2 9, thereby preventing the rotating shaft 2 from rotating, so that in the event of an abnormality in the equipment, the discharge door body 4 can still maintain a certain degree of support and self-locking property, greatly reducing the risk of material leakage.

[0037] Reference Figure 3 and Figure 4 The limit assembly includes a fixed block 11 symmetrically fixedly connected to one side of the discharge port of the mixer body 1, and a screw rod 12 is rotatably connected inside the fixed block 11. One end of the fixed block 11 is fixedly connected to a servo motor 13, and the output end of the servo motor 13 is fixedly connected to one end of the screw rod 12. An adjusting block 14 is threadedly connected to the screw rod 12. A slot 20 is provided on one side of the unloading door body 4. The shape and size of the slot 20 are consistent with one end of the adjusting block 14. A clamping piece is provided at one end of the adjusting block 14. Both ends of the adjusting block 14 are fixedly connected with T-shaped blocks 15. Slide grooves 16 are provided on both sides of the fixed block 11, and the T-shaped block 15 is slidably connected in the slide groove 16.

[0038] When in use, first start the servo motor 13 to drive the screw rod 12 to rotate, and as the screw rod 12 rotates, the adjusting block 14 will move inside the fixed block 11 according to the guidance of the T-shaped block 15 and the slide groove 16, so that one end of the adjusting block 14 gradually enters the interior of the card slot 20. Through the mutual connection between the adjusting block 14 and the card slot 20, the position of the discharge door body 4 after closing can be limited, so that the discharge door body 4 can always fit with the discharge port and maintain a closed state, preventing material leakage or accidental discharge, thereby reducing material waste, improving production efficiency, and reducing safety risks in the workplace. At the same time, it can also prevent the discharge door body 4 from accidentally opening due to material pressure or gravity, reducing damage to the discharge door body 4.

[0039] Reference Figure 3 and Figure 4 The clamping parts include grooves 17 symmetrically opened on both sides of one end of the adjusting block 14, the interior of the grooves 17 is fixedly connected to the spring 18, the interior of the grooves 17 is slidably connected to the clamping block 19, one end of the clamping block 19 is fixedly connected to one end of the spring 18, and limiting grooves 21 are opened on both sides of the interior of the clamping groove 20, the end of the clamping block 19 away from the spring 18 is arc-shaped, and the shape and size of the limiting groove 21 are consistent with the arc-shaped end of the clamping block 19.

[0040] During use, as one end of the adjusting block 14 enters the slot 20, the inner wall of the slot 20 will squeeze the arc-shaped end of the block 19 and squeeze it into the inside of the groove 17. When one end of the adjusting block 14 is fully inserted into the slot 20, the position of the limiting groove 21 and the groove 17 will be on the same horizontal line. At this time, the block 19 will lose the squeezing of the inner wall of the slot 20, and according to the rebound of the spring 18, one end of the block 19 will be squeezed into the inside of the limiting groove 21. In this way, through the mutual cooperation between the block 19 and the limiting groove 21, the position of the discharge door body 4 is locked again, reducing the possibility of the discharge door body 4 loosening and opening.

[0041] Reference Figure 2 and Figure 3 A sealing plate 22 is fixedly connected to the top of the discharge door body 4.

[0042] During use, the provided sealing plate 22 can effectively improve the sealing between the discharge door body 4 and the discharge port, preventing material leakage or accidental discharge, thereby reducing material waste.

[0043] The implementation principle of the mixer discharge door with self-locking function in this embodiment is as follows: when in use, the cylinder 5 is first started to operate to push the connecting block 6 to move, thereby pushing the connecting rod 1 7 to rotate through the movement of the connecting block 6. As the connecting block 6 gradually moves, the connecting block 6, the connecting rod 1 7 and the connecting rod 2 9 are in the same straight line. At this time, the rotation guidance of the connecting rod 1 7 will make the connecting plate 8 drive the rotating shaft 2 to rotate, thereby driving the discharge door body 4 to fit tightly with the discharge port at the bottom of the mixer body 1 through the support plate 3. After the discharge door body 4 fits the discharge port, the servo motor 13 can be started to operate to drive the screw rod 12 to rotate. As the screw rod 12 rotates, the adjusting block 14 will move inside the fixed block 11 according to the guidance of the T-shaped block 15 and the slide groove 16, thereby making one end of the adjusting block 14 gradually enter the interior of the slot 20. Through the mutual connection between the adjusting block 14 and the slot 20, the discharge door body 4 can be adjusted. The position after closing is limited, so that the discharge door body 4 can always fit with the discharge port and maintain the closed state, preventing material leakage or accidental discharge, thereby reducing material waste, improving production efficiency, and reducing safety risks in the workplace. At the same time, it can also prevent the discharge door body 4 from being accidentally opened due to material pressure or gravity, reducing damage to the discharge door body 4. As one end of the adjusting block 14 enters the card slot 20, the inner wall of the card slot 20 will squeeze the arcuate end of the card block 19 and squeeze it into the inside of the groove 17. When one end of the adjusting block 14 is fully inserted into the inside of the card slot 20, the position of the limiting groove 21 and the groove 17 will be on the same horizontal line. At this time, the card block 19 will lose the squeezing of the inner wall of the card slot 20, and according to the rebound of the spring 18, one end of the card block 19 will be squeezed into the inside of the limiting groove 21. In this way, through the mutual cooperation of the card block 19 and the limiting groove 21, the position of the discharge door body 4 is locked again, reducing the situation that the discharge door body 4 is loose and opened.

[0044] In addition, in daily use, if after the discharge door body 4 is closed, the equipment malfunctions and the cylinder 5 and the servo motor 13 cannot operate, at this time, because the connecting block 6, the connecting rod 1 7 and the connecting rod 2 9 are in the same horizontal straight line, the fixing plate 10 can limit the interference between the connecting block 6, the connecting rod 1 7 and the connecting rod 2 9, thereby preventing the rotating shaft 2 from rotating. In this way, when the equipment malfunctions, the discharge door body 4 can still maintain a certain degree of support and self-locking, greatly reducing the risk of material leakage.
