Technical Field
[0001] The utility model relates to the technical field of brick making, in particular to a pressure head vibration reduction and limiting mechanism. Background Art
[0002] Brick making machine is a mechanical equipment for producing block bricks. It generally uses stone powder, fly ash, slag, slag, gravel, sand, water, etc. as raw materials. It is made into block bricks through processes such as mixing, extruding bricks, drying, baking, and sintering.
[0003] The brick making machine in the prior art usually includes a brick making frame, a mold frame and a pressing head. When making bricks, the material is first placed in the mold frame, and then the pressing head is pressed down to press the material in the mold frame to form bricks. However, the pressing head of the brick making machine in the prior art has poor vibration reduction effect when pressing the material. In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus the present case was produced. Utility Model Content
[0004] The utility model aims to solve at least one of the technical problems in the above-mentioned technology to a certain extent. To this end, the purpose of the utility model is to provide a pressure head vibration reduction and limiting mechanism, which has a good vibration reduction effect when the pressure head is pressed down, and by setting a limiting plug block and a limiting slot, the pressure head will not shake forward and backward or left and right when it is pressed down, so that the pressure head is more stable when it is pressed down.
[0005] In order to achieve the above-mentioned purpose, the utility model proposes a pressure head vibration reduction and limiting mechanism, including a pressure head frame, a vibration reduction component, a locking component, a limiting component, a transition frame and a pressure head;
[0006] The vibration reduction assembly includes a vibration reduction block, an upper screw, an upper nut, a lower screw and a lower nut. The vibration reduction block is located between the pressure head frame and the transition frame. One end of the upper screw is arranged in the vibration reduction block, and the other end of the upper screw passes through the pressure head frame and is connected to the upper nut. One end of the lower screw is arranged in the vibration reduction block, and the other end of the lower screw passes through the transition frame and is connected to the lower nut.
[0007] The locking assembly includes a locking screw, an upper locking nut and a lower locking nut. The locking screw passes through the pressure head frame and the transition frame. The upper locking nut is connected to the upper end of the locking screw, and the lower locking nut is connected to the lower end of the locking screw.
[0008] The limiting assembly is arranged between the pressure head frame and the transition frame, and the limiting assembly includes a limiting plug and a limiting convex seat. The height of the limiting plug is less than the thickness of the vibration damping block. A limiting slot for inserting the limiting plug is formed in the limiting convex seat, and the inner diameter of the limiting slot is equal to the outer diameter of the limiting plug.
[0009] The pressure head is arranged on the transition frame.
[0010] Furthermore, the limiting plug block is arranged on the transition frame, and the limiting convex seat is arranged on the pressure head frame.
[0011] Furthermore, the limiting plug block is arranged on the pressure head frame, and the limiting boss is arranged on the transition frame.
[0012] Furthermore, the vibration reduction assembly is arranged in multiple groups, and the vibration reduction blocks of the multiple groups of vibration reduction assemblies are evenly distributed between the pressure head frame and the transition frame.
[0013] Furthermore, in the same set of vibration reduction components, the axial center line of the upper screw coincides with the axial center line of the lower screw.
[0014] Furthermore, a guide surface is provided at the end of the limiting plug block.
[0015] Furthermore, the pressure head is fixed on the transition frame by bolts.
[0016] Furthermore, it also includes a brick-making frame and a pressure head cylinder. The pressure head cylinder is arranged on the brick-making frame, and the pressure head cylinder is connected to the pressure head frame and drives the pressure head frame to rise and fall.
[0017] Furthermore, a guide rod is arranged on the brick making frame, and the pressing head frame is movably arranged on the guide rod through a guide sleeve assembly.
[0018] Furthermore, the guide sleeve assembly includes a guide sleeve and a guide sleeve locking piece. The guide sleeve is movably arranged on the guide rod, and the guide sleeve locking piece is connected to the guide sleeve after passing through the pressure head frame.
[0019] After adopting the above structure, the pressure head vibration reduction and limiting mechanism of the utility model has at least the following beneficial effects:
[0020] First, when in use, the pressure head frame rises or falls under the action of the pressure head oil cylinder. When the pressure head frame falls, it drives the pressure head to fall synchronously. The pressure head falls and compacts the material in the mold frame. In the process of the pressure head descending and compacting the material, the vibration reduction block is squeezed, thereby achieving a vibration reduction effect, making the pressure head less likely to be damaged. Since the height of the limit plug is less than the thickness of the vibration reduction block, when the vibration reduction block is squeezed, the limit plug moves in the limit slot. Since the inner diameter of the limit slot is equal to the outer diameter of the limit plug, when the vibration reduction block is squeezed, the pressure head will not shake back and forth or left and right under the action of the limit plug and the limit slot, thereby making the pressure head more stable when pressing down.
[0021] Second, in the initial state and the compression state, the ends of the limit plug are located in the limit slot. In the initial state, the limit plug does not move, while in the compression state, the limit plug moves along the limit slot. When the pressure head compacts the material tightly, the end of the limit plug can rest against the bottom of the limit slot, thereby preventing the vibration damping block from being further compressed and preventing the vibration damping block from being damaged due to excessive compression.
[0022] Third, by setting a locking assembly, the locking assembly connects the pressure head frame and the transition frame together, so that the vibration damping block will not deform downward under the gravity of the transition frame. In the initial state, the upper locking nut abuts against the surface of the pressure head frame, and the lower locking nut abuts against the surface of the transition frame to connect the pressure head frame and the transition frame together. In the compressed state, since the vibration damping block is compressed, the lower locking nut will be away from the surface of the transition frame, that is, there is a gap between the lower locking nut and the surface of the transition frame. After the compression is completed, when the pressure head rises, the lower locking nut abuts against the surface of the transition frame again under the elastic action of the vibration damping block. Therefore, the locking assembly does not affect the vibration damping effect of the vibration damping assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0030] like Figures 1 to 4As shown, a pressure head vibration reduction and limiting mechanism of the utility model includes a pressure head frame 1, a vibration reduction assembly 2, a locking assembly 3, a limiting assembly 4, a transition frame 5 and a pressure head 6; the vibration reduction assembly 2 includes a vibration reduction block 21, an upper screw rod 22, an upper nut 23, a lower screw 24 and a lower nut 25, the vibration reduction block 21 is located between the pressure head frame 1 and the transition frame 5, one end of the upper screw rod 22 is arranged in the vibration reduction block 21, and the other end of the upper screw rod 22 passes through the pressure head frame 1 and is connected with the upper nut 23, one end of the lower screw 24 is arranged in the vibration reduction block 21, and the other end of the lower screw 24 passes through the transition frame 5 and is connected with the lower nut 25; the locking assembly 3 includes a locking Screw 31, upper locking nut 32 and lower locking nut 33, the locking screw 31 passes through the pressure head frame 1 and the transition frame 5, the upper locking nut 32 is connected to the upper end of the locking screw 31, and the lower locking nut 33 is connected to the lower end of the locking screw 31; the limit assembly 4 is arranged between the pressure head frame 1 and the transition frame 5, the limit assembly 4 includes a limit plug 41 and a limit boss 42, the height of the limit plug 41 is less than the thickness of the vibration damping block 21, and a limit slot 421 is formed in the limit boss 42 for the limit plug 41 to be inserted, and the inner diameter of the limit slot 421 is equal to the outer diameter of the limit plug 41; the pressure head 6 is arranged on the transition frame 5.
[0031] In this way, the present utility model relates to a pressure head vibration reduction and limiting mechanism. When in use, the pressure head frame 1 rises or falls under the action of the pressure head oil cylinder 8. When the pressure head frame 1 falls, it drives the pressure head 6 to fall synchronously. The pressure head 6 falls and compacts the material in the mold frame. In the process of the pressure head 6 falling and compacting the material, the vibration reduction block 21 is squeezed, thereby achieving a vibration reduction effect, making the pressure head 6 not easy to be damaged. Since the height of the limit plug 41 is less than the thickness of the vibration reduction block 21, when the vibration reduction block 21 is squeezed, the limit plug 41 moves in the limit slot 421, and since the inner diameter of the limit slot 421 is equal to the outer diameter of the limit plug 41, when the vibration reduction block 21 is squeezed, the pressure head 6 will not shake back and forth or left and right under the cooperation of the limit plug 41 and the limit slot 421, so that the pressure head 6 is more stable when pressing down.
[0032] In the initial state and the compression state, the ends of the limit plug 41 are both located in the limit slot 421. In the initial state, the limit plug 41 does not move, while in the compression state, the limit plug 41 moves along the limit slot 421. When the pressure head 6 compacts the material tightly, the end of the limit plug 41 can rest against the bottom of the limit slot 421, thereby preventing the vibration damping block 21 from being further compressed and preventing the vibration damping block 21 from being damaged due to excessive compression.
[0033] By setting the locking assembly 3, the locking assembly 3 connects the pressure head frame 1 and the transition frame 5 together, so that the vibration damping block 21 will not deform downward under the gravity of the transition frame 5. In the initial state, the upper locking nut 32 abuts against the surface of the pressure head frame 1, and the lower locking nut 33 abuts against the surface of the transition frame 5 to connect the pressure head frame 1 and the transition frame 5 together. In the compressed state, since the vibration damping block 21 is compressed, the lower locking nut 33 will be away from the surface of the transition frame 5, that is, there is a gap between the lower locking nut 33 and the surface of the transition frame 5. After the pressing is completed, when the pressure head 6 rises, under the elastic action of the vibration damping block 21, the lower locking nut 33 abuts against the surface of the transition frame 5 again. Therefore, the locking assembly 3 does not affect the vibration damping effect of the vibration damping assembly 2.
[0034] Optionally, the limiting plug block 41 is arranged on the transition frame 5, and the limiting convex seat 42 is arranged on the pressure head frame 1. Of course, the limiting plug block 41 can also be arranged on the pressure head frame 1, and the limiting convex seat 42 is arranged on the transition frame 5 accordingly.
[0035] Furthermore, the vibration reduction assembly 2 is provided in multiple groups, and the vibration reduction blocks 21 of the multiple groups of vibration reduction assemblies 2 are evenly distributed between the pressure head frame 1 and the transition frame 5. By providing multiple groups of vibration reduction assemblies 2, the vibration reduction and buffering effects are further improved.
[0036] In this example, in the same set of vibration reduction components 2 , the axial center line of the upper screw 22 coincides with the axial center line of the lower screw 24 , thereby preventing the vibration reduction block 21 from being subjected to uneven force when being squeezed, thereby increasing the service life of the vibration reduction block 21 .
[0037] Furthermore, a guide surface 411 is provided at the end of the limiting plug 41. By providing the guide surface 411, it is convenient to connect the limiting plug 41 with the limiting slot 421 during installation. In this example, the pressure head 6 is fixed to the transition frame 5 by bolts, such as the pressure head 6 is fixed to the transition frame 5 by multiple bolts, so that the pressure head 6 is firmly fixed to the transition frame 5.
[0038] In some examples, a brick-making frame 7 and a pressure head oil cylinder 8 are also included. The pressure head oil cylinder 8 is arranged on the brick-making frame 7, and the pressure head oil cylinder 8 is connected to the pressure head frame 1 and drives the pressure head frame 1 to rise and fall. When in use, the piston rod of the pressure head oil cylinder 8 drives the pressure head frame 1 to rise or fall, and when the pressure head frame 1 falls, the pressure head 6 is driven to fall synchronously to realize the pressing and forming of the material.
[0039] In some examples, a guide rod 71 is provided on the brick making frame 7, and the pressure head frame 1 is movably provided on the guide rod 71 through a guide sleeve assembly 9. By providing the guide sleeve assembly 9, the pressure head frame 1 is more stable when it is lifted or lowered. The guide sleeve assembly 9 includes a guide sleeve 91 and a guide sleeve locking member 92. The guide sleeve 91 is movably provided on the guide rod 71. The guide sleeve locking member 92 passes through the pressure head frame 1 and is connected to the guide sleeve 91. In this way, the pressure head frame 1 is firmly fixed on the guide sleeve 91, and the guide sleeve 91 can be lifted or lowered smoothly along the guide rod 71, further improving the stability of the pressure head frame 1 when it is lifted or lowered.
[0040] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
