Description

Technical Field

[0001] This utility model relates to the technical field of friction brick presses, specifically a safety hopper for a friction brick press. Background Technology

[0002] Friction brick press is a traditional brick and tile forming equipment. It mainly uses friction transmission to drive the crankshaft connecting rod mechanism, converting rotational motion into linear pressing motion to pressurize and form brick blanks. Its structure is relatively simple and easy to operate. It was once widely used in small and medium-sized brick and tile factories, and is especially suitable for producing solid clay bricks, hollow bricks, etc.

[0003] In existing technologies, friction brick presses require a hopper for auxiliary feeding of raw materials. However, the accumulation of raw materials inside the hopper can easily lead to blockages due to compression, affecting subsequent stable feeding. Furthermore, the pressure load on the hopper from the compressed material inside creates a significant pressure load. If the operating efficiency of the friction brick press cannot be adjusted according to the material level inside the hopper, the hopper's lifespan will be affected. Therefore, this application designs a safety hopper for friction brick presses. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a safety hopper for a friction brick press to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0006] This utility model provides a safety hopper for a friction brick press, including a hopper and a support. The support is fixedly connected to the bottom of the hopper. A through groove is opened at the connection between the hopper and the support. A cylinder is fixedly connected to the side wall of the hopper. A fixed shaft is fixedly connected to the hopper inside the through groove. A sleeve is movably sleeved on the shaft wall of the fixed shaft. A tilting frame is fixedly connected to the sleeve wall. A connecting plate is fixedly connected to the top of the tilting frame. The piston rod end of the cylinder extends into the interior of the hopper and is hinged to a connecting seat. The end of the connecting plate opposite to the tilting frame is hinged inside the connecting seat.

[0007] Preferably, the bracket has multiple threaded holes inside.

[0008] Preferably, the bracket is fixedly connected to a connecting frame at the bottom of the through groove, and a material guide cover is provided at the bottom of the connecting frame.

[0009] Preferably, the material guide cover is configured as a folded square tube.

[0010] Preferably, a plurality of levers are fixedly connected to the sleeve wall, and the ends of the plurality of levers opposite to the sleeve are respectively provided with rounded corners.

[0011] Preferably, a controller and multiple pressure sensors are fixedly connected to the side wall of the hopper, and multiple wires are electrically connected to the connection points of the multiple pressure sensors and the controller.

[0012] Preferably, the hopper has a rectangular groove inside, and the plurality of pressure sensors extend into the hopper inside the rectangular groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This friction brick press uses a safety hopper. When the piston rod of the cylinder extends, it pushes the connecting plate to cause the tilting frame to rotate upward around the fixed axis, pushing the raw material in the hopper towards the through groove. When the piston rod retracts, the tilting frame returns to its original position, completing one feeding action. Multiple levers on the cylinder wall of the tilting frame rotate synchronously with the tilting frame, which can more evenly agitate the raw material and avoid raw material clumping and blockage. At the same time, the rounded corner design can reduce scratch damage to the raw material.

[0015] 2. The friction brick press uses a safety hopper. The guide cover below the bottom connecting frame of the through groove is set as a folded square tube. The length can be flexibly adjusted according to the height of the brick press inlet, so as to accurately guide the raw materials into the brick press and reduce the spillage of raw materials.

[0016] 3. This friction brick press uses a safety hopper. Multiple pressure sensors inside the rectangular groove of the hopper are used to monitor the amount of raw material in the hopper. The pressure sensors are electrically connected to the controller on the side wall of the hopper via wires. When the amount of raw material is sufficient, the raw material applies pressure to the pressure sensor, and the sensor transmits the signal to the controller. The controller maintains the normal feeding rhythm. When the amount of raw material is insufficient, the pressure signal weakens or disappears, and the controller can issue an early warning to remind the operator to replenish the material in time to avoid the brick press running idle and causing equipment damage.

[0021] A safety hopper for a friction brick press, such as Figure 1-3 The device includes a hopper 1 and a support 2. The support 2 is fixedly connected to the bottom of the hopper 1. A through groove is provided at the connection between the hopper 1 and the support 2. A cylinder 6 is fixedly connected to the side wall of the hopper 1. A fixed shaft 7 is fixedly connected to the hopper 1 inside the through groove. A sleeve 8 is movably sleeved on the shaft wall of the fixed shaft 7. A tilting frame 9 is fixedly connected to the sleeve wall of the sleeve 8. A connecting plate 10 is fixedly connected to the top of the tilting frame 9. The piston rod end of the cylinder 6 extends into the interior of the hopper 1 and is hinged to a connecting seat 11. The end of the connecting plate 10 facing away from the tilting frame 9 is hinged to the interior of the connecting seat 11.

[0022] The bracket 2 has multiple threaded holes 3 inside. The bracket 2 is fixedly connected to the bottom of the through groove with a connecting frame 4. The bottom of the connecting frame 4 is provided with a guide cover 5. The guide cover 5 is set as a folded square tube. Multiple levers 12 are fixedly connected to the cylinder wall of the sleeve 8. The ends of the multiple levers 12 away from the sleeve 8 are respectively provided with rounded corners.

[0023] In summary: The hopper 1 serves as a container for storing and transporting raw materials, while the support 2 at the bottom provides stable support. Multiple threaded holes 3 inside the support 2 are used to fix the hopper in a designated position on the friction brick press with bolts, ensuring that the hopper will not shift during feeding. The through groove at the connection between the hopper 1 and the support 2 is the channel for transporting raw materials. The cylinder 6 on the side wall of the hopper 1 serves as a power source, driving the tilting frame 9 to move through the extension and retraction of the piston rod. The tilting frame 9 is movably sleeved on the fixed shaft 7 through the sleeve 8 and can rotate around the fixed shaft 7. The connecting plate 10 at the top of the tilting frame 9 is hinged to the connecting seat 11 at the end of the piston rod of the cylinder 6, forming a crank-connecting rod structure. The connecting seat 11 hinged at the end of the piston rod of the cylinder 6 can swing flexibly, providing a certain amount of movement along the trajectory of the connecting plate 10 as it swings along the fixed shaft 7, ensuring stable transmission of the cylinder 6 to the connecting plate 10.

[0024] When the piston rod of cylinder 6 extends, it pushes the connecting plate 10 to drive the tilting frame 9 to rotate upward around the fixed shaft 7, pushing the raw material in hopper 1 towards the through groove. When the piston rod retracts, the tilting frame 9 returns to its original position downward, completing one feeding action. Multiple levers 12 on the cylinder wall of the tilting frame 9 rotate synchronously with the tilting frame, which can more evenly agitate the raw material and avoid raw material clumping and blockage. At the same time, the rounded corner design can reduce scratch damage to the raw material.

[0025] The guide cover 5 below the bottom connecting frame 4 of the channel is set as a folded square tube, which can be flexibly adjusted according to the height of the brick press inlet to accurately guide the raw materials into the brick press and reduce the spillage of raw materials.

[0026] In order to monitor the material storage status inside hopper 1 in real time and accurately, such as Figure 1-3 As shown, a controller 13 and multiple pressure sensors 14 are fixedly connected to the side wall of the hopper 1. Multiple wires 15 are electrically connected to the connection points of the multiple pressure sensors 14 and the controller 13. A rectangular groove is opened inside the hopper 1, and the multiple pressure sensors 14 extend into the hopper 1 located inside the rectangular groove.

[0027] Multiple pressure sensors 14 inside the rectangular groove of the hopper 1 are used to monitor the amount of raw material in the hopper. The pressure sensors 14 are electrically connected to the controller 13 on the side wall of the hopper through wires 15. When the amount of raw material is sufficient, the raw material applies pressure to the pressure sensor 14, and the sensor transmits the signal to the controller 13. The controller maintains the normal feeding rhythm. When the amount of raw material is insufficient, the pressure signal weakens or disappears, and the controller 13 can issue an early warning to remind the operator to replenish the material in time to avoid the brick press running idle and causing equipment damage.

[0028] In addition, the pressure sensor 14 can also indirectly monitor whether there is abnormal accumulation or blockage of raw materials. If the pressure in a certain area rises abnormally, it may indicate that a blockage has occurred at that location. The controller 13 can then stop the machine or adjust the tilting rack 9 to prevent the hopper from being overloaded and damaged due to blockage.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
