Description

Technical Field

[0001] This invention relates to the field of brick-making machine technology, and more specifically, to a guide column assembly mechanism for an energy-saving brick-making machine with a special mold vibration mechanism. Background Technology

[0002] The vibration brick-making machine is a widely used molding equipment in the building materials industry. It combines mold vibration with hydraulic pressing to compress mixtures of cement, fly ash, and sand into energy-saving bricks. Its core moving components include an upper mold frame, a lower mold frame, and a multi-guide column assembly mechanism connecting the two. The guide column assembly mechanism typically consists of a guide sleeve (or guide column outer sleeve) fixed to the frame and guide columns sliding through it, ensuring precise guidance of the upper mold during high-frequency vertical reciprocating motion. In actual operation, the guide columns must withstand tens of thousands of impacts and vibrations per day, while also being exposed to a high-concentration dust environment, placing extremely high demands on the sealing and wear resistance of the guiding system.

[0003] However, existing guide post assembly mechanisms generally employ a passive dust prevention method using smooth guide posts with rubber sealing rings or scraper lips. While this structure can block some external dust, it cannot remove micron-sized particles that have already infiltrated the gap between the guide post and the guide sleeve. Over time, dust caking leads to increased friction, sluggish movement, and even surface damage. Although some solutions have attempted to introduce air curtains or external blowing systems, these often rely on additional air sources, resulting in high energy consumption and fixed airflow direction, failing to meet the diverse dust removal needs of reciprocating motion.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a guide column assembly mechanism for an energy-saving brick-making machine with special mold vibration. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a guide column assembly mechanism for an energy-saving brick-making machine with special mold vibration.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a guide column assembly mechanism for an energy-saving brick-making machine, comprising a guide column disposed on a clamping block and a guide column inner sleeve sleeved on the outside of the guide column, wherein the guide column inner sleeve and the guide column form a sliding guide fit, characterized in that: a spiral groove is provided on the outer circumferential surface of the guide column, wherein during the movement of the guide column relative to the guide column inner sleeve, the spiral groove is used to discharge dust particles that have entered between the two along the extension direction of the spiral groove to the end area of ​​the guide sleeve;

[0007] The guide column assembly mechanism of this energy-saving brick-making machine also includes:

[0008] An inner sleeve of a guide post is set outside the inner sleeve of the guide post, and an air cavity is formed between the inner sleeve of the guide post and the outer sleeve of the guide post. The inner sleeve of the guide post is connected to the air cavity through a piston hole. An air pressure regulating component is set between the piston hole and the clamping block to change the air cavity pressure when the guide post and the inner sleeve of the guide post are displaced.

[0009] The jet mechanism is mounted on the outer sleeve of the guide column and is connected to the air pressure regulator via a transmission mechanism. The jet mechanism is also equipped with an air pipe. When the guide column is pressed down, the air pressure regulator controls the air chamber pressure to increase, and the gas in the air chamber is ejected through the air pipe and forms an air curtain on the outer side of the inner sleeve of the guide column. When the guide column is pressed down to its maximum stroke, the transmission mechanism controls the jet mechanism to bring the air pipe closer, causing the inner sleeve surface to deflect. When the guide column rises and the air chamber pressure decreases, dust-laden air is drawn in through the air pipe.

[0010] Preferably, the jetting mechanism includes a turntable disposed on the inner sleeve of the guide post, and a hollow rod is installed between the turntable and the outer sleeve of the guide post via a rotary seal. One end of the hollow rod is connected to the air chamber, and the air pipe is installed on the other end of the hollow rod via a corrugated pipe.

[0011] Preferably, the transmission mechanism includes a gear set disposed in the air chamber and meshing with each other, and the air pressure regulating component is provided with a telescopic rod, and one of the gears is connected to the telescopic end of the telescopic rod through a spiral groove guide pin mechanism.

[0012] Preferably, the gear corresponding to the hollow rod in the gear set is connected to the end of the hollow rod extending into the air chamber. The turntable is provided with a curved groove, and the curved groove is in contact with the outer surface of the air pipe. The bottom surface of the turntable and the outer surface of the hollow rod are respectively provided with tooth 2 and tooth 1, and tooth 2 and tooth 1 are meshed.

[0013] Preferably, the outer surface of the hollow rod inside the air cavity is configured with a hollow structure.

[0014] Preferably, a baffle is provided on the inner surface of the segment near the telescopic end of the telescopic rod, and the baffle is in contact with the end of the telescopic end.

[0015] Preferably, the air pressure regulating component includes a rod fixedly mounted on the clamping block, and a piston is provided after the end of the rod extends into the piston hole, the piston being adapted to the piston hole, and the telescopic rod is provided on the lower surface of the piston.

[0016] Preferably, the trachea is tapered, and the diameter near the trachea opening is smaller than the diameter away from the trachea opening.

[0017] Preferably, a rubber ring that fits onto the surface of the guide post is provided at the edge of the top opening of the inner sleeve of the guide post.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The spiral grooves on the guide post surface utilize reciprocating linear motion to achieve directional dust conveying, which can self-clean without rotation, and the higher the frequency of use, the better the cleaning effect;

[0020] 2. The air chamber is powered by the movement of the guide column. The downward jet of air forms a positive pressure air curtain to effectively repel dust, while the upward negative pressure actively sucks in the dust from the top, achieving bidirectional active protection.

[0021] 3. The air tube adopts a conical design to increase the jet flow rate and suction negative pressure intensity, thereby enhancing the air curtain barrier effect and dust collection efficiency;

[0022] 4. The gear set not only transmits motion, but also achieves mechanical logic judgment of "only driving when compressed and locked, and only resetting when stretched to the end" through torque threshold design. This avoids false triggering caused by friction interference from the telescopic rod, and ensures that the tracheal deflection is strictly limited to the end of the stroke, making the action precise and reliable.

Detailed Implementation

[0032] like Figure 1-7 As shown, the present invention provides a guide column 1 assembly mechanism for an energy-saving brick-making machine with special mold vibration, comprising a guide column 1 disposed on a clamping block 2, and a guide column inner sleeve 3 sleeved on the outside of the guide column 1, wherein the guide column inner sleeve 3 forms a sliding guide fit with the guide column 1. The feature is that: the outer circumferential surface of the guide column 1 is provided with a spiral groove 21. During the movement of the guide column 1 relative to the guide column inner sleeve 3, the spiral groove 21 is used to discharge dust particles that have entered between the two along the extension direction of the spiral groove 21 to the end area of ​​the guide sleeve.

[0033] Although the guide post 1 and the guide sleeve are fitted with precision (e.g., H8 / f7 tolerance grade), and the clearance on one side is controlled within the range of 0.10–0.25 mm, under high-frequency vibration and high-dust conditions, such as during the operation of a mold vibration brick making machine, micron-sized particles such as cement and fly ash in the environment can still intrude into the annular gap between the guide post 1 and the guide sleeve through gravity settling, airflow disturbance, or equipment opening and closing actions.

[0034] To solve the above-mentioned problem of removing intrusive dust, the present invention has a continuous right-hand spiral groove 21 processed on the outer peripheral surface of the guide post 1; the pitch of the spiral groove 21 is 8–20 mm, the groove depth is 0.3–1.0 mm, and the groove shape is a U-shaped with a rounded bottom. Its depth is greater than the particle size of the largest dust particle in the environment, so as to ensure that the particles can fall into the groove rather than cross the groove ridge.

[0035] Specifically: When the guide post 1 reciprocates linearly relative to the guide sleeve (as in the downstream pressing stage), the dust particles intruding into the gap are effectively captured and directionally transported along the spiral path under the combined action of the following mechanisms:

[0036] First, the dust particles are constrained by the inner wall of the guide sleeve. Due to the limited clearance, the particles cannot suspend freely, but are "squeezed" between the side wall of the spiral groove 21 and the inner wall of the guide sleeve during the movement of the guide post 1, forming a three-point contact state (the particles simultaneously contact the bottom of the groove, the side wall of the groove, and the inner wall of the guide sleeve), thus being mechanically clamped.

[0037] Secondly, the inclined sidewall of the spiral groove 21 generates a normal reaction force during the linear motion of the guide post 1. Taking the right-hand spiral groove 21 as an example, when the guide post 1 moves downward, the right sidewall of the groove (facing the relative motion direction) applies an upward-sloping normal force N to the clamped particles. According to the principle of force decomposition, this normal force N can be decomposed into two components:

[0038] An axial component Nz, directed upwards along the axis of guide post 1;

[0039] A circumferential component Nθ, the direction of which is clockwise around guide post 1 (viewed from top to bottom);

[0040] Driven by these two components, the dust particles move downwards along the guide post 1 while simultaneously moving upwards along the trajectory of the spiral groove 21. Their movement trajectory is a spiral upward path, and they are eventually continuously transported to the upper opening area of ​​the guide sleeve.

[0041] Furthermore, the high-frequency vibration of the mold vibration brick making machine itself plays an auxiliary role: the vibration keeps the dust particles in a loose and active state, making it easier for them to fall into the clamping area between the spiral groove 21 and the inner wall of the guide sleeve, and reducing the static friction resistance between the particles and the metal surface, thereby improving the conveying efficiency.

[0042] The higher the operating frequency and the more frequent the reciprocating stroke, the higher the efficiency of the spiral groove in removing intruding dust. Specifically, each reciprocating motion of the guide post 1 relative to the guide sleeve drives the spiral groove to perform a "capture-grip-convey" cleaning cycle on the dust particles in the gap. As the operating frequency increases, the number of cleaning cycles completed per unit time increases accordingly, and the time window for dust accumulation in the gap is greatly compressed, thereby effectively preventing particle deposition, caking, or embedding on the friction pair surface. This characteristic makes the present invention particularly suitable for high-frequency, high-dust working conditions (such as fully automatic block forming machines, mold vibration brick making machines, powder pressing and molding equipment, etc.). Its cleaning ability is positively correlated with the working intensity of the equipment, achieving an adaptive protection effect where the higher the working intensity, the better the dust removal effect.

[0043] The guide column 1 assembly mechanism of this energy-saving brick-making machine also includes:

[0044] A guide post outer sleeve 11 is provided outside the guide post inner sleeve 3, and an air cavity 13 is formed between the guide post inner sleeve 3 and the guide post outer sleeve 11. The guide post inner sleeve 3 is connected to the air cavity 13 through the piston hole 4. An air pressure regulating component is provided between the piston hole 4 and the clamping block 2 to change the pressure of the air cavity 13 when the guide post 1 and the guide post inner sleeve 3 are displaced.

[0045] The jet mechanism is mounted on the outer sleeve 11 of the guide column and is connected to the air pressure regulator through the transmission mechanism. The jet mechanism is also equipped with an air pipe 7. When the guide column 1 is pressed down, the air pressure regulator controls the pressure of the air chamber 13 to increase. The gas in the air chamber 13 is ejected through the air pipe 7 and forms an air curtain on the outside of the inner sleeve 3 of the guide column. When the guide column 1 is pressed down to the maximum stroke, the transmission mechanism controls the jet mechanism to deflect the air pipe 7 close to the surface of the inner sleeve 3 of the guide column. When the guide column 1 rises, the pressure of the air chamber 13 is reduced, and dust-laden air is drawn in through the air pipe 7.

[0046] The energy-saving brick-making machine guide column 1 assembly mechanism of the present invention further integrates self-powered air curtain dust prevention and return active dust suction functions on the basis of traditional guide structure.

[0047] The mechanism includes a guide post 1, an inner guide post sleeve 3, and an outer guide post sleeve 11. The inner guide post sleeve 3 is fitted around the outer periphery of the guide post 1 and forms a sliding guide engagement with the guide post 1. The outer guide post sleeve 11 is fixed to the equipment frame and fits outside the inner guide post sleeve 3, forming a closed annular air chamber 13 between the two. The inner guide post sleeve 3 is provided with a piston hole 4, and a pressure regulating component is provided between the piston hole 4 and the clamping block 2 area on the guide post 1. When the guide post 1 undergoes axial displacement relative to the inner guide post sleeve 3, the pressure regulating component adjusts the volume of the air chamber 13 accordingly, thereby changing the internal pressure of the air chamber 13.

[0048] An air jet mechanism is provided on the guide post outer sleeve 11, which is linked to the aforementioned air pressure regulating component via a transmission mechanism. The air jet mechanism includes an adjustable air pipe 7, the outlet of which faces the upper region of the guide post inner sleeve 3. During the downward pressing of the guide post 1, the guide post 1 drives the air pressure regulating component to compress the air chamber 13, causing the pressure inside the air chamber 13 to increase. The high-pressure gas is ejected at high speed through the air pipe 7, forming a positive pressure air curtain that diffuses from the inside out at the inlet on the outer side of the guide post inner sleeve 3. This air curtain effectively prevents external dust from intruding into the guide gap, achieving active protection during the downward phase.

[0049] When the guide post 1 is pressed down to the maximum stroke position, the air pressure regulator triggers the transmission mechanism, causing the outlet end of the air pipe 7 in the jet mechanism to deflect around its mounting axis, so that its pipe opening is close to the top surface of the inner sleeve 3 of the guide post, and the jet direction is adjusted to be close to the outer wall of the inner sleeve 3 of the guide post; this state is in preparation for the return cleaning.

[0050] After the brick making is completed, the guide column 1 begins to rise and reset, and the air chamber 13 generates negative pressure due to the increase in volume. Under this negative pressure, the air pipe 7 draws in air in the reverse direction. Since the outlet of the air pipe 7 has deflected to the vicinity of the top opening of the inner sleeve 3 of the guide column at this time, the air drawn in mainly comes from this area, thereby drawing in the loose dust attached to the top of the guide column 1 or accumulated at the inlet of the inner sleeve 3 of the guide column into the air chamber 13. This design is not a passive dust intake, but rather an intentional use of the negative pressure naturally formed by the return of the guide column 1 to carry out directional suction of high-risk pollution areas.

[0051] To prevent the inhaled dust from accumulating in the air chamber 13 and causing blockage or secondary pollution, this solution includes a miniature dust pump installed on the outside of the guide column jacket 11. The pump's inlet is connected to the air chamber 13 and can be activated during each return stroke to extract the dust-laden gas from the air chamber 13 and transport it to the central dust removal system of the equipment. Since the amount of dust inhaled at one time is small and limited to a local area, the power required by the miniature dust pump is reduced, far lower than that of conventional dust collection devices. In other words, the main driving force for dust inhalation and removal still comes from the reciprocating motion of the guide column 1 itself, and the miniature pump only undertakes an auxiliary transfer function. The overall system still maintains a high degree of energy saving.

[0052] It should be noted that the guide gap between the air chamber 13 and the guide post 1 and guide post inner sleeve 3 is completely isolated by the dynamic sealing structure in the piston hole 4 area. The sucked-in dust exists only inside the air chamber 13 and cannot enter the guide friction pair area, thus preventing the aggravation of wear or jamming between the guide post 1 and guide post inner sleeve 3. In addition, the inner wall of the air chamber 13 can be treated with a dust-repellent coating to further reduce the tendency of dust adhesion and ensure that the miniature dust pump can efficiently complete the chamber cleaning task.

[0053] In summary, this embodiment cleverly utilizes the pressure changes generated by the movement of the guide column 1 to achieve dust protection by forming an air curtain for dust repellency during downward jetting and suction for dust removal during return. It is especially suitable for high-frequency, high-dust environments such as mold vibration brick making machines, and effectively solves the problems of short lifespan and frequent maintenance caused by dust accumulation in traditional guiding mechanisms.

[0054] In another embodiment of the present invention, the jetting mechanism includes a turntable 9 disposed on the inner sleeve 3 of the guide column. A hollow rod 10 is installed between the turntable 9 and the outer sleeve 11 of the guide column via a rotary seal. One end of the hollow rod 10 is connected to the air chamber 13, and an air pipe 7 is installed on the other end of the hollow rod 10 via a bellows 8. When the guide column 1 moves downward, the pressure in the air chamber 13 increases, and gas is ejected from the air pipe 7 through the hollow rod 10 to form an air curtain to prevent dust from entering.

[0055] The transmission mechanism includes a gear set that is disposed in the air chamber 13 and meshes with each other. The gear set consists of a first gear 16, a second gear 17, a third gear 18 and a fourth gear 20 that are rotatably mounted. The second gear 17 is located between the first gear 16 and the fourth gear 20. The fourth gear 20 is rotatably disposed on the outside of the inner sleeve 3 of the guide post, forming a transmission chain. The air pressure regulating component is fixed on the clamping block 2 and includes a rod 5 and a piston 15 located at its end. The piston 15 is adapted to be inserted into the piston hole 4 of the inner sleeve 3 of the guide post. The telescopic rod 19 is fixed to the lower surface of the piston 15 and moves together with the piston 15.

[0056] The telescopic rod 19 has a multi-segment nested structure. A baffle 24 is provided on the inner surface of each segment near the telescopic end. This baffle 24 initially remains in contact with the lowermost telescopic end. During the initial downward movement of the guide post 1, the piston 15 drives the entire telescopic rod 19 downward. At this time, the segments of the telescopic rod 19 can slide relative to each other and are in a compressible state. Therefore, although there is displacement, the telescopic end has not yet applied effective drive to the spiral groove 21 guide pin mechanism.

[0057] As the guide post 1 continues to descend to near its maximum stroke, the telescopic rod 19 is compressed to its limit, and the baffle 24 is fully pressed against the end of the telescopic rod, making the entire telescopic rod 19 a rigid unit. Thereafter, further downward movement of the piston 15 no longer causes the telescopic rod 19 to shorten, but instead forces the locked telescopic end to move linearly. This telescopic end is connected to gear 3 18 via a guide pin mechanism of the helical groove 21, and its linear displacement is converted into the rotational motion of gear 3 18 under the action of the inclined surface of the helical groove 21.

[0058] The rotation of gear 3 18 is transmitted to gear 16 via gear 2 17 and gear 4 20, which drives the hollow rod 10 connected to it to rotate. The outer surface of the hollow rod 10 extending into the air chamber 13 is provided with tooth 1 22, which meshes with tooth 2 23 on the bottom side of the turntable 9, thereby driving the turntable 9 to rotate. The turntable 9 is provided with a curved groove 6, and the outer side of the air pipe 7 is attached to the curved groove 6; when the turntable 9 rotates, the curved groove 6 pushes the air pipe 7 to bend and deflect, so that its pipe opening turns from the initial position to the direction close to the top surface of the inner sleeve 3 of the guide post, completing the switch from air curtain to dust collection mode.

[0059] When the guide column 1 begins to rise, the piston 15 drives the telescopic rod 19 to return to its original position. At this time, the telescopic rod 19 is in a stretched state, and each section can be freely extended. Therefore, in the initial stage of rising, the telescopic end does not generate reverse drive, the gear 3 18 remains stationary, and the air pipe 7 remains in a deflected state so as to use the negative pressure of the air chamber 13 to suck in the dust from the top.

[0060] As the guide column 1 rises to near its initial position, the telescopic rod 19 is stretched to its maximum length, and the baffle 24 re-fits the end of the telescopic rod, restoring the telescopic rod 19 to a rigid whole. The subsequent upward movement pulls the telescopic end upward, driving the gear 18 to rotate in the opposite direction via the guide pin mechanism of the spiral groove 21. This, in turn, causes the hollow rod 10 and the turntable 9 to rotate in the opposite direction via the gear set. Guided by the curved groove 6, the air pipe 7 returns to its original vertical or outward-sloping position, preparing for the formation of a dustproof air curtain when the guide column 1 is pressed down again.

[0061] It is worth noting that the gear set not only undertakes the function of motion transmission, but also plays a role in dynamic force control and stroke locking. Since the telescopic rod 19 has a multi-segment nested structure, there is sliding friction resistance between each segment. During reciprocating motion, the following may occur: in the early stage of descent, the telescopic end is driven prematurely due to resistance, or in the late stage of ascent, the release is delayed due to jamming, thus causing the trachea 7 to deflect at the wrong time.

[0062] This invention, through the rational design of the gear set's transmission ratio and meshing stiffness, ensures that the driving torque transmitted by the gear set is much greater than the sliding friction resistance between the segments of the telescopic rod 19. Therefore, during the downward movement of the guide column 1, the telescopic rod 19 is preferentially compressed as a whole. Only when it is compressed to its limit (the baffle 24 fits against the telescopic end) and forms a rigid body will subsequent displacement effectively drive the spiral groove 21 guide pin mechanism to rotate the gear 3 18. Similarly, during the upward movement of the guide column 1, the telescopic rod 19 is preferentially stretched as a whole. Only when it is fully stretched can it continue to rise and drive the gear 3 18 in the opposite direction through the spiral groove 21 guide pin mechanism.

[0063] This mechanism ensures that the deflection action of the trachea 7 is strictly limited to the end position of the guide post 1's stroke, avoiding malfunctions caused by internal friction fluctuations in the telescopic rod 19, and achieving highly reliable adaptive switching; the gear set, as the drive, plays a mechanical limiting role here, with outstanding technical effect;

[0064] It needs to be explained that the purpose of rotating the air tube 7 is to prevent dust from being effectively blocked by directly spraying air onto the surface of the guide post 1 or the guide post 1 sleeve. This is because such an approach would cause the high-speed airflow to radially impact the surface of the guide post inner sleeve 3, failing to create a continuous and stable outward positive pressure barrier in front of the gap inlet. Instead, the impact and rebound of the airflow would generate local vortices and negative pressure zones, engulfing surrounding suspended dust and actively pressing it into the tiny gap between the guide post 1 and the guide post 1 sleeve, thus having the opposite effect of conveying dust rather than blocking it. A truly effective air curtain must form an air curtain that diffuses from the inside out outside the guide gap inlet, using positive pressure to repel external dust and prevent it from approaching the gap. Therefore, during the downward phase of the guide post 1, the air tube 7 must remain vertical or tilted outward to establish the correct air curtain direction, and should not spray air onto the surface of the guide post 1 or the guide post 1 sleeve.

[0065] It should be noted that the specific structure of the spiral groove 21 guide pin mechanism is as follows: a spiral groove is formed circumferentially on the inner surface of gear 18, and the direction of rotation of the spiral groove matches the direction of movement of guide post 1; a radially protruding guide pin is provided at the telescopic end of telescopic rod 19, which is embedded and slidably fitted in the spiral groove. When telescopic rod 19 makes axial linear movement, the guide pin slides along the inclined surface of the spiral groove, forcing gear 18 to rotate around its axis, thereby converting the linear displacement of telescopic rod 19 into continuous rotation of gear 18;

[0066] Preferably, the air pipe 7 is tapered, with the diameter near the opening of the air pipe 7 being smaller than the diameter further away. This tapered structure can throttle and accelerate the airflow. According to the principle of fluid continuity, with a constant gas flow rate, the reduced pipe diameter significantly increases the airflow velocity at the opening, thereby enhancing the dynamic pressure and penetration of the air curtain and effectively improving its dust-blocking ability. Simultaneously, the high-speed airflow forms a more concentrated jet at the outlet, which helps to build a stable and dense positive pressure barrier in front of the guide column 1 inlet, preventing external dust from flowing around and intruding. Furthermore, during the dust suction phase of the guide column 1, the smaller pipe diameter helps to increase the local negative pressure intensity, enhancing the collection efficiency of loose dust in the top area.

[0067] A rubber ring is provided at the top opening edge of the inner sleeve 3 of the guide post, adhering to the surface of the guide post 1. This rubber ring acts as a flexible dust scraper lip, maintaining a tight fit with the surface of the guide post 1 during its reciprocating motion. It effectively scrapes away loose dust adhering to the surface of the guide post 1 during its return upward stroke, preventing dust from being carried into the guide gap. Simultaneously, the rubber ring has a certain degree of elasticity, accommodating slight swaying or surface wear of the guide post 1, maintaining stable contact without generating excessive frictional resistance or the risk of jamming. Furthermore, this rubber ring works synergistically with the air curtain and spiral groove 21 dust removal mechanism: the air curtain blocks most of the external dust, the spiral groove 21 removes particles that have already intruded into the gap, and the rubber ring acts as a final mechanical barrier, intercepting residual dust, forming multiple layers of protection and significantly improving the reliability and service life of the guiding mechanism in high-dust environments.

[0068] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
