Description

Technical Field

[0001] The invention relates to the technical field of mixer design, in particular to a bottom material output mechanism of a mixer. Background Art

[0002] As a key equipment in industrial production, mixers are widely used in chemical, pharmaceutical, food, construction and other fields. In these fields, it is often necessary to mix a variety of materials with different properties to meet specific process requirements. Traditional mixers may use top or side discharge methods, but in some cases, these methods may have problems such as uneven discharge, easy clogging or complicated operation. Therefore, the bottom discharge mechanism came into being and became an effective solution to these problems.

[0003] The applicant has found that the discharge port valves of existing mixers still require a lot of manual intervention, and most of the valves are installed on the edge of the discharge port. During long-term use, the part in contact with the material is prone to wear, which affects the sealing and service life of the valve. When the wear is severe, it may even cause the valve to be unable to close or close loosely, further aggravating the problems of uneven discharge and leakage. For example, a concrete mixer with high mixing efficiency announced in the authorized patent number CN106584675A has improved the blockage of the discharge part, but still has not effectively solved the shortcomings of the valve.

[0004] Therefore, the applicant proposes a bottom material discharging mechanism of a mixer to solve the above technical problems. Summary of the invention

[0007] Preferably, a linear guide is installed on one side wall of the slide rail, and the linear guide is located on one side of the top fixing frame. A linear pulley is installed on one side wall of the long connecting rod, and the linear pulley slides linearly in contact with the bottom of the linear guide, and moves along the arc surface on one side of the linear guide when the cover is sealed.

[0008] Preferably, connecting rod lower limit rods are fixed behind the long connecting rod on both sides of the top fixing frame. When the linear pulley fits on the bottom of the linear guide rail for linear sliding, the connecting rod lower limit rod fits against the side wall of the long connecting rod, and the oil cylinder is in a horizontal state at this time.

[0009] Preferably, a lateral positioning block is installed on the side wall of the connecting block between the two slide rails, and the lateral positioning block can be abutted against the notch at one end of the top plate, and at this time the linear pulley moves to the arc position on one side of the linear guide rail.

[0010] Preferably, a cylinder fixing block is respectively installed on both sides of the two slide rails, the cylinder fixing blocks are fixedly connected by a fixing rod, and the cylinder fixing blocks are rotatably connected to a cylinder seat fixed to the outside of the cylinder.

[0011] Preferably, rack seat connecting plates are respectively installed on the sides and tops of both sides of the two slide rails, and the rack seat connecting plates are used to be fixedly connected to the crossbeams inside the rack.

[0012] Preferably, the frame is provided with a limit clamping plate at the bottom of the platform on which the mixing box is installed, and the limit clamping plate is inserted into the notches at the top of the long connecting rod and the short connecting rod when the cover is sealed.

[0013] Preferably, a connecting rod connecting block is rotatably connected between adjacent sides of the long connecting rod and the short connecting rod close to the top fixing plate.

[0014] Preferably, a sealing ring is installed on the top of the sealing cover, and the sealing ring is in contact with the inner wall of the bottom outlet of the mixing box.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention adopts the design of the discharge structure. When the discharge is opened, the telescopic rod of the oil cylinder contracts, and the cover first rotates and sinks and then retreats. In this way, the discharge port of the mixing box can be automatically opened without manual intervention, and the cover does not contact the material, which effectively extends the service life.

[0017] 2. The present invention uses a connecting rod connecting block to ensure good stability between the long connecting rod and the short connecting rod close to one end of the top fixing plate, thereby strengthening the connection strength between the two and preventing this end from breaking due to the impact force of stirring. It should be noted that the long connecting rod and the short connecting rod rotate in coordination with the connecting rod connecting block.

[0018] 3. The present invention designs a limit card plate, so that when the long connecting rod and the short connecting rod rotate to drive the cover to rotate for cover sealing, the limit card plate will passively snap into the notches on the top of the long connecting rod and the short connecting rod for limiting, thereby enhancing stability.

When the linear pulley moves to the arc surface at one end of the linear guide rail, the lateral positioning block just abuts against the notch at one end of the top fixing plate. At this time, the short connecting rod and the long connecting rod rotate upward, and the linear pulley just rolls upward along the arc surface at one end of the linear guide rail. Then, when the cover is opened, the linear pulley will also move downward due to the limit rotation. Naturally, the cover can also be rotated first, and the long connecting rod touches the lower limit rod of the connecting rod and then retreats horizontally, so that the overall operation is very stable and efficient.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0036] like Figure 1-Figure 11 As shown, a bottom discharge material mechanism of a mixer of the present invention comprises a frame 2, two slide rails 3 are installed on the inner side of the frame 2 and a mixing box 1 is installed on a side platform, a discharge material mechanism is installed on the slide rail 3, including an oil cylinder 4 rotatably installed under the slide rail 3, a telescopic rod of the oil cylinder 4 is fixed on a joint 5, the joint 5 is passed through by a top cover push rod 6, short connecting rods 7 are fixed on both sides of the top cover push rod 6, one end of the short connecting rod 7 is rotatably connected to the side wall of a top fixing plate 8, a sealing cover 9 on the top of the top fixing plate 8 blocks the bottom opening of the mixing box 1, long connecting rods 10 are also rotatably installed on both sides of the top fixing plate 8, one end of the long connecting rod 10 and the short connecting rod 7 are rotatably connected to a top fixing frame 11, a top plate 12 is fixed on the top of the top fixing frame 11, a sliding block 13 is installed on the top of the top plate 12, and the sliding block 13 slides at the bottom of the slide rail 3.

[0037] When the oil cylinder 4 is in a state of being horizontal, the sealing cover 9 is slightly tilted. When the oil cylinder 4 is started, the driving joint 5 drives the top cover push rod 6 to move. The top cover push rod 6 applies thrust to the short connecting rod 7, the long connecting rod 10, the top fixing plate 8, the top fixing frame 11 and the top plate 12 and makes each structure cooperate with the two slide rails 3 to move horizontally through the slider 13. When it moves to the end of the slide rail 3, the top fixing frame 11 and the top plate 12 cannot move. Then the telescopic rod of the oil cylinder 4 continues to extend, so that the short connecting rod 7 rotates upward, the top fixing plate 8 rotates and drives the long connecting rod 10 to rotate in coordination. In this process, the top fixing plate 8 and the sealing cover 9 rotate and finally fit into the sealing part of the bottom end of the mixing box 1, and the oil cylinder 4 is tilted. Then when opening, the telescopic rod of the oil cylinder 4 contracts, and the sealing cover 9 will first rotate and sink and then retreat. In this way, the material outlet of the mixing box 1 can be automatically opened without manual intervention, and the sealing cover 9 does not contact the material, which effectively prolongs the service life.

[0038] A linear guide 14 is installed on the side wall of a slide rail 3, and the linear guide 14 is located on one side of the top fixing frame 11. A linear pulley 15 is installed on the side wall of a long connecting rod 10. The linear pulley 15 fits in the bottom of the linear guide rail 14 for linear sliding, and when the cover 9 is blocked, the linear pulley 15 moves along the arc surface of one side of the linear guide rail 14. Connecting rod lower limit rods 16 are fixed on both sides of the top fixing frame 11 behind the long connecting rod 10. When the linear pulley 15 fits in the bottom of the linear guide rail 14 for linear sliding, the connecting rod lower limit rod 16 fits with the side wall of the long connecting rod 10, and at this time the cylinder 4 is in a horizontal state, and a lateral positioning block 17 is installed on the side wall of the connecting block between the two slide rails 3. The lateral positioning block 17 can be abutted against the notch at one end of the top plate 12, and at this time the linear pulley 15 moves to the arc surface position on one side of the linear guide rail 14.

[0039] Through the design of the auxiliary parts, in the initial state, one end of the long connecting rod 10 is in contact with the lower limit rod 16 of the connecting rod, and the linear pulley 15 on the side of the long connecting rod 10 is in contact with the bottom of the linear guide rail 14 and slides linearly, and the linear pulley 15 is located at one end of the rotation point of the long connecting rod 10 and is away from the lower limit rod 16 of the connecting rod. Then, at this time, the long connecting rod 10 cannot rotate, and the long connecting rod 10 and the short connecting rod 7 and the top fixing plate 8 rotate synchronously due to the shaft linkage, and then can maintain linear motion. When the linear pulley 15 moves to the linear When the pulley 15 moves to the arc surface at one end of the linear guide 14, the lateral positioning block 17 just contacts the notch at one end of the top plate 12, and the blockage is performed at this time. The short connecting rod 7 and the long connecting rod 10 rotate upward, and the linear pulley 15 just rolls upward along the arc surface at one end of the linear guide 14. Then, when the cover 9 is opened, the linear pulley 15 will also move downward due to the limit rotation. Naturally, the cover 9 can also be rotated first, and the long connecting rod 10 touches the lower limit rod 16 of the connecting rod and then retreats horizontally, making the overall operation very stable and efficient.

[0040] A cylinder fixing block 18 is installed on both sides of the two slide rails 3 respectively. The cylinder fixing blocks 18 are fixedly connected by fixing rods, and the cylinder fixing blocks 18 are rotatably connected through a cylinder seat 19 fixed to the outside of the cylinder 4. Frame seat connecting plates 20 are installed on the sides and top of both sides of the two slide rails 3 respectively. The frame seat connecting plates 20 are used to be fixedly connected to the crossbeam inside the frame 2.

[0041] By means of the cylinder fixing block 18 and the cylinder seat 19, the two sides of the cylinder 4 can be stably connected and supported for rotation, and the two slide rails 3 can be stably fixed on the crossbeam inside the frame 2 through the frame seat connecting plate 20 to avoid shaking during the operation of the discharging mechanism, thereby effectively improving the sliding stability of the cylinder 4 and the top plate 12.

[0042] The frame 2 is provided with a limit clamping plate 21 at the bottom of the platform on which the mixing box 1 is installed. The limit clamping plate 21 is inserted into the notches at the top of the long connecting rod 10 and the short connecting rod 7 when the cover 9 is sealed.

[0043] By designing the limiting card plate 21, when the long connecting rod 10 and the short connecting rod 7 rotate to drive the cover 9 to rotate and close, the limiting card plate 21 will passively snap into the notches on the top of the long connecting rod 10 and the short connecting rod 7 to limit the position, thereby enhancing stability.

[0044] A connecting rod connecting block 23 is rotatably connected between the adjacent sides of the long connecting rod 10 and the short connecting rod 7 close to the top fixing plate 8 .

[0045] The connecting rod connecting block 23 ensures good stability between the long connecting rod 10 and the short connecting rod 7 close to one end of the top fixing plate 8, thereby strengthening the connection strength between the two and preventing this end from breaking due to the impact force of stirring. It should be noted that the long connecting rod 10 and the short connecting rod 7 rotate in coordination with the connecting rod connecting block 23.

[0046] A sealing ring 22 is installed on the top of the sealing cover 9 , and the sealing ring 22 is in contact with the inner wall of the bottom outlet of the mixing box 1 .

[0047] The sealing performance of the cover 9 can be effectively improved by the sealing ring 22, and the sealing ring 22 is corrosion-resistant and durable.

[0048] Working principle: Start the oil cylinder 4 to drive the joint 5 to drive the top cover push rod 6 to move. The top cover push rod 6 applies thrust to the short connecting rod 7, the long connecting rod 10, the top fixing plate 8, the top fixing frame 11 and the top plate 12, and makes each structure move horizontally through the slider 13 in cooperation with the two slide rails 3. At the same time, the linear pulley 15 slides linearly at the bottom of the linear guide rail 14. When it moves to the end of the slide rail 3, the linear pulley 15 moves to the arc surface at one end of the linear guide rail 14, and the lateral positioning block 17 just contacts the notch at one end of the top plate 12. The top fixing frame 11 and the top plate 12 cannot move. Then the oil cylinder 4 The telescopic rod continues to extend, causing the short connecting rod 7 to rotate upward, and the top fixing plate 8 rotates and drives the long connecting rod 10 to rotate in coordination. In this process, the top fixing plate 8 and the cover 9 rotate and finally fit together at the seal at the bottom end of the mixing box 1, and the cylinder 4 tilts. Then, the material is added for mixing. When it is opened for discharge, the telescopic rod of the cylinder 4 contracts, and the linear pulley 15 rolls upward along the arc surface at one end of the linear guide rail 14. Then, when the cover 9 is opened, the linear pulley 15 will also move downward due to the limit rotation. Naturally, the cover 9 can also be rotated first, and the long connecting rod 10 touches the lower limit rod 16 of the connecting rod and then retreats horizontally to complete the opening operation.
