Description

Technical Field

[0001] This invention is an automated production line for processing facing bricks, belonging to the field of building materials production equipment. Background Technology

[0002] In the brick pressing production process, raw materials such as sand are first filled into the forming groove of the lower mold base of the brick press by a horizontal feeder. Then, the upper and lower molds are closed and pressed to form the green body. The scraping mechanism is the key link to ensure the forming quality. Its core function is to scrape off the excess raw material along the surface of the lower mold base after the sand is filled, so that the sand in the groove is of uniform height and the surface is flat, providing a uniform raw material base for subsequent pressing and forming, and ensuring that the brick green body has uniform thickness and dense structure.

[0003] In the field of building material processing such as facing bricks, traditional translation feeders generally adopt an open design at the bottom without a dedicated closed or guiding structure. Their core operating logic is: the hopper is driven by a cylinder to make a back-and-forth reciprocating translational movement. The bottom of the hopper has an opening. During the movement, the sand is evenly spread from the opening to the forming area of ​​the lower mold base, completing the quantitative and uniform filling of raw materials, which is suitable for the feeding needs of continuous batch production of facing bricks.

[0004] Existing translational feeders of this type have high requirements for the precision of component fitting. After long-term use, wear can easily lead to increased fitting gaps and decreased fit, resulting in sand leakage. Furthermore, the fully open bottom design not only allows sand to easily scatter and cause sand waste, but also fails to effectively restrain the sand, exacerbating the adverse effects of precision deviations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide an automated production line for brick processing.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an automatic production line for brick processing, the structure of which includes: a brick press, wherein a retractable scraping and feeding mechanism is installed in the middle of the brick press, a pressing brick module is provided in front of the scraping and feeding mechanism, the pressing brick module includes a lower mold base and an upper pressing mold, a waste sand discharge trough is provided on one side of the scraping and feeding mechanism, and a material support plate is provided at the bottom of the scraping and feeding mechanism;

[0007] The brick press is equipped with a sliding guide rail in the middle that is at the same level as the top surface of the lower mold base, and the scraping and feeding mechanism slides back and forth on the sliding guide rail;

[0008] The material scraping and feeding mechanism further comprises a material supporting and limiting assembly, a material scraping and guiding assembly and a driving assembly.

[0009] Preferably, the material scraping and guiding assembly is fastened and installed in front of the material scraping and feeding mechanism, and comprises an outer mounting plate, an inner scraping plate, a set of guide rails, a set of pressing mechanisms, two sets of guide rails and two sets of pressing mechanisms.

[0010] The outer mounting plate is fixedly assembled at the front end surface of the material scraping and feeding mechanism, and a avoiding sliding groove is formed in the middle of the outer mounting plate.

[0011] A set of pressing mechanisms is symmetrically arranged above the left and right sides of the inner scraping plate, and the end of the set of pressing mechanisms is fastened and installed on the outer mounting plate.

[0012] Preferably, two sets of guide rails are parallelly arranged and fixedly installed at the left and right ends in front of the outer mounting plate, and the scraping member is slidingly assembled on the two sets of guide rails.

[0013] Two sets of pressing mechanisms are symmetrically installed above the scraping member, and are used to continuously apply downward pressure to the scraping member, so that the bottom of the scraping member is always tightly attached to the top surface of the lower mold base and the bearing surface of the guide rail.

[0014] Preferably, a fixed scraping base plate is integrally formed on the bottom of the side of the outer mounting plate facing the inner scraping plate, and a triangular scraping boss is integrally formed on the bottom of the inner scraping plate facing the inner side of the material scraping and feeding mechanism.

[0015] A sand guiding slope is arranged on the front end upper surface of the material supporting and limiting assembly, and a waste sand recycling groove is formed in the bottom of the front end of the material supporting and limiting assembly.

[0016] As preferred, the waste sand discharge groove on the lower die seat is integrally formed with a limiting support ridge on the left and right sides near the middle part, and the top surface of the limiting support ridge is flush with the top surface of the lower die seat;

[0017] A waste sand recovery assembly is arranged at the front of the lower die seat and below the waste sand discharge groove.

[0018] As preferred, the waste sand recovery assembly comprises a sand guide chute, a water injection device and a waste sand recovery barrel. The sand guide chute is a semi-closed tubular structure, and a feeding opening is formed at the top end of the sand guide chute corresponding to the position of the waste sand discharge groove. The sand guide chute is tightly installed below the waste sand discharge groove, and the inside of the sand guide chute is inclined from high on the left to low on the right to form a guide channel with a preset slope.

[0019] The water injection device is tightly installed on the inner side wall of the brick press by bolts, and is used to deliver water flow into the chute. The waste sand recovery barrel is placed below the discharge end of the sand guide chute at the front of the lower die seat. The bottom end of the sand guide chute is connected to the waste sand recovery barrel.

[0020] As preferred, the scraping and feeding mechanism comprises a driving assembly, which comprises a double-acting cylinder, a first support arm and a second support arm. The double-acting cylinder is installed in the middle of the brick press. The front end of the first support arm is installed on the rear end of the rack of the brick press by a hinge. The piston rod end of the double-acting cylinder is connected to the middle part of the first support arm by a fastening block. The second support arm is axially connected and installed at the tail of the first support arm. The other end of the second support arm is connected to the left and right side walls of the scraping and feeding mechanism. The double-acting cylinder, the first support arm and the second support arm are mirror-symmetrically arranged on the left and right sides of the scraping and feeding mechanism.

[0021] A sand stirring assembly is arranged inside the scraping and feeding mechanism. A sand conveying track is arranged at the front of the brick press. A sand grinder is arranged at the rear of the sand conveying track.

[0022] As preferred, the material supporting bottom plate moves forward together with the scraping and feeding mechanism. When the material supporting bottom plate passes through the waste sand discharge groove, the movement is paused by the limiting structure. Then the scraping and feeding mechanism is separated from the material supporting bottom plate and continues to move forward, pushing the face brick blank carried thereby into the forming cavity of the lower die seat to complete the feeding. After the feeding is completed, the scraping and feeding mechanism is retracted back. When the scraping and feeding mechanism is retracted to the corresponding position of the material supporting bottom plate, the material supporting bottom plate is retracted back synchronously with the scraping and feeding mechanism. During the retraction, the scraping and feeding mechanism sweeps the residual blank waste sand into the waste sand discharge groove to complete the cleaning.

[0023] The automatic production line for face brick processing has the following effects:

[0024] 1. Through the cooperation of the waste sand recycling groove formed by the triangular scraping convex boss at the bottom of the inner scraping plate, the fixed scraping base plate at the bottom of the outer mounting plate, and the cooperation of the front end of the material supporting bottom plate and the limiting convex boss, the problem of incomplete raw material recycling and serious waste in traditional tile production line is solved. Traditional equipment can only simply clean the surface residual material, and a large amount of raw material is lost due to ineffective recycling. The accumulation of residual material can cause equipment jamming and affect the precision of subsequent processes. In the design, the triangular scraping convex boss uses the slope structure to efficiently guide most of the recycled raw material back to the scraping and feeding mechanism for recycling. The fixed scraping base plate closely adheres to the surface of the lower mold seat, scraping off a small amount of residual material in the gap and corners and guiding it into the waste sand recycling groove, which not only improves the utilization rate of raw materials, but also avoids the interference of residual material accumulation on equipment operation, reducing equipment maintenance frequency and cost.

[0025] 2. Through the linkage design of the two sets of pressing mechanisms and the scraping piece, in combination with the limiting support rib integrally formed on both sides of the waste sand discharge groove, the problem of incomplete residual material cleaning and easy jamming of equipment movement in traditional tile production is completely solved. Traditional equipment relies on a single scraping structure and lacks continuous pre-tightening and precise guiding design, which causes the lower mold seat surface and the edge of the cavity to easily accumulate sand material. These residual materials can directly affect the flatness of the subsequent green body forming, and even cause the green body to be damaged during mold closing. In the design, the two sets of pressing mechanisms are symmetrically arranged above the scraping piece, continuously applying downward uniform pre-tightening force to the scraping piece, ensuring that the bottom of the scraping piece is always in close contact with the top surface of the lower mold seat and the bearing surface of the guide rail. Whether it is the initial cleaning after the green body is pushed or the secondary scraping when the mechanism is retracted, the residual sand and debris can be completely removed, providing a clean and flat working reference for subsequent forming. In addition, the residual material scraped by the scraping piece can directly fall into the waste sand discharge groove below, eliminating the need for additional manual cleaning, reducing the process interval, and improving the automation level and work efficiency of the production line.

[0026] 3. Through the integrated design of the material supporting bottom plate, the core problems of traditional tile production equipment caused by the lack of effective bearing structure, such as material leakage, high precision dependence, and unstable operation, are solved. In the traditional equipment, the area below the scraping and feeding mechanism is usually designed as a suspended structure without a dedicated bearing and protection structure. On the one hand, it can cause some raw materials that have not entered the cavity to leak from the lower gap. On the other hand, traditional equipment requires high overall assembly precision, increasing the difficulty of maintenance. In the design, the material supporting bottom plate, as the bearing core of raw material transportation, not only provides a stable support surface when the scraping and feeding mechanism moves forward, ensuring smooth movement and accurate feeding, but also avoids feeding deviation caused by force deviation. It can completely cover the waste sand discharge groove below during the raw material pushing process, forming a closed protection. At the same time, the linkage design of the material supporting bottom plate and the scraping and feeding mechanism can realize stable transportation without relying on extremely high equipment assembly precision, reducing the dependence of the equipment on machining and assembly precision, and improving the reliability and durability of the equipment operation.

The extension 3221 passes through the avoiding sliding groove 3211 and is in sliding cooperation with the set of guide sliding rails 323a. The outer mounting plate 321 serves as the installation reference for each component. The avoiding sliding groove 3211 formed in the middle of the outer mounting plate 321 provides space redundancy for the movement of the inner scraping plate 322.

[0054] The waste sand discharge groove 2a1 on the lower mold base 2a is wider than the width of the scraping member 325, and the waste sand discharge groove 2a1 is integrally formed with a limiting support rib 2a2 on the left and right sides near the middle part, and the top surface of the limiting support rib 2a2 is flush with the top surface of the lower mold base 2a; the front of the lower mold base 2a and the position corresponding to the lower part of the waste sand discharge groove 2a1 are provided with a waste sand recovery assembly 4, and the size of the waste sand discharge groove 2a1 opened on the lower mold base 2a is adapted to the core purpose of ensuring that the scraping range of the scraping member 325 during the forward and backward scraping movement can completely cover the slot area of the waste sand discharge groove 2a1, so that all the sand particles scraped off by the scraping member 325 can fall into the discharge groove without omission, and the limiting support rib 2a2 can provide a continuous and flat movement support surface for the scraping member 325 and the material supporting bottom plate 311 through the design of “the top surface being flush with the top surface of the lower mold base 2a”, which can avoid the jamming or tilting of the components due to the existence of the discharge groove when the scraping member 325 scrapes along the surface of the lower mold base 2a or the material supporting bottom plate 311 translates above the discharge groove, thereby ensuring the stability of the scraping and horizontal movement, and the flush top surface can also assist in calibrating the scraping height of the scraping member 325, so as to ensure that the bottom of the scraping member 325 and the surface of the lower mold base 2a always maintain close contact.

[0055] The waste sand recovery assembly 4 includes a sand guide chute 41, a water injection device 42 and a waste sand recovery bucket 43, the sand guide chute 41 is a semi-closed tubular structure, an inlet opening 411 is formed at the position corresponding to the waste sand discharge groove 2a1 at the top end of the sand guide chute 41, the sand guide chute 41 is tightly installed below the waste sand discharge groove 2a1, and the inside of the sand guide chute 41 is arranged in a left-high-right-low inclination to form a pre-set slope guide channel 412; the semi-closed structure of the sand guide chute 41 can effectively prevent the waste sand from scattering outward during the water-sand mixed conveying process, the inlet opening 411 is formed at the position corresponding to the waste sand discharge groove 2a1 at the top end of the sand guide chute 41, the size of the opening is matched with the slot of the waste sand discharge groove 2a1, and the chute is fixed below the waste sand discharge groove 2a1 through a tight installation mode, so as to ensure that the waste sand falling from the discharge groove can completely fall into the inlet opening 411, in addition, the inside of the sand guide chute 41 is arranged in a left-high-right-low inclination to form a pre-set slope guide channel 412, and the slope design provides guidance and power assistance for the flow of the water-sand mixture, after the water injection device 42 injects water flow into the chute, the water flow forms a stable flow trend along the pre-set slope, the sand falls into the chute and fully mixes with the water flow, and the water-sand mixture slides along the guide channel 412 by means of the impact force and driving effect of the water flow.

[0056] The water injection device 42 is mounted on the inner side wall of the brick press 1 by bolt fastening, and is used to deliver water flow into the chute. The waste sand recovery bucket 43 is placed in front of the lower die seat 2a and below the discharge end of the sand guide chute 41. The bottom end of the sand guide chute 41 is connected to the waste sand recovery bucket 43. After the water flow is injected, it not only can moisten the surface of the sand particles and effectively suppress the dust generated during the waste sand delivery process, but more importantly, it can provide flow power for the waste sand. Combined with the inclined slope of the sand guide chute 41, it forms a delivery mode of "water flow driving sand material". The waste sand recovery bucket 43 is the final collection component of waste sand and sewage, and is placed in front of the lower die seat 2a and directly below the discharge end of the sand guide chute 41. The bottom end of the sand guide chute 41 is connected to the waste sand recovery bucket 43.

Batch collection of water-sand mixture can be realized. After collecting to the preset capacity, manual or mechanical follow-up processing of the mixture can be facilitated.

[0057] The scraping and feeding mechanism 3 comprises a driving assembly 33, the driving assembly 33 comprising a double-acting cylinder 331, a first supporting arm 332, and a second supporting arm 333, the double-acting cylinder 331 being installed in the middle of the brick press 1, the first supporting arm 332 being installed at the front end of the rear end of the rack of the brick press 1 through a hinged piece, the piston rod end of the double-acting cylinder 331 being connected to the middle of the first supporting arm 332 through a fastening block, the second supporting arm 333 being installed on the tail of the first supporting arm 332 in an axial connection, the other end of the second supporting arm 333 being connected to the left and right side walls of the scraping and feeding mechanism 3, the double-acting cylinder 331, the first supporting arm 332, and the second supporting arm 333 being mirror-symmetrically arranged on the left and right sides of the scraping and feeding mechanism 3; the scraping and feeding mechanism 3 constructs a power transmission system through the cooperative matching of the double-acting cylinder 331, the first supporting arm 332, and the second supporting arm 333, and each component is designed in a mirror-symmetric layout to ensure the stability of the movement of the mechanism and the balance of the stress, wherein the double-acting cylinder 331 is fixedly installed in the middle of the brick press 1, has the characteristics of bidirectional output power, and can drive the piston rod to extend and retract, respectively, to provide stable power for the forward and backward movement of the scraping and feeding mechanism 3; the front end of the first supporting arm 332 is connected to the rear end of the rack of the brick press 1 through a hinged piece, the hinged structure enables the first supporting arm 332 to rotate around the hinged point to provide a flexible movement track for power transmission; the piston rod end of the double-acting cylinder 331 is fixedly connected to the middle of the first supporting arm 332 through a fastening block, this rigid connection mode can ensure that the linear movement of the piston rod is converted into the rotary movement of the first supporting arm 332, the second supporting arm 333 is installed on the tail of the first supporting arm 332 in an axial connection, the other end of the second supporting arm 333 is fixedly connected to the left and right side walls of the scraping and feeding mechanism 3, forming a complete power transmission path of “double-acting cylinder 331→first supporting arm 332→second supporting arm 333→scraping and feeding mechanism 3”, when the piston rod of the double-acting cylinder 331 extends, the first supporting arm 332 is pushed to rotate forward around the front hinged point, and then drives the scraping and feeding mechanism 3 to move forward along the sliding guide rail 12 through the second supporting arm 333 to realize the pushing of the blank; when the piston rod retracts, the first supporting arm 332 is pulled to rotate backward, and the scraping and feeding mechanism 3 is retracted through the second supporting arm 333 to complete the scraping of the waste sand.

[0058] The interior of the scraping and feeding mechanism 3 is provided with a sand stirring assembly 34, the rear of the brick press 1 is provided with a sand conveying track 5, the rear of the sand conveying track 5 is provided with a sand grinder 6, the sand stirring assembly 34 arranged in the scraping and feeding mechanism 3 has the function of pre-mixing and loosening the sand entering the mechanism, and the stirring assembly can make the components of the sand more uniformly mixed through the continuous movement of the rotating blades or stirring rods, the sand conveying track 5 arranged at the rear of the brick press 1 serves as an intermediate channel for conveying the sand from the storage link to the scraping and feeding mechanism 3, and the sand grinder 6 arranged at the rear of the sand conveying track 5 can crush the sand with oversized particle size to the particle size range required for the production of ceramic tiles through the extrusion and grinding action of the internal grinding rollers or grinding discs.

[0059] Sand pretreatment stage: the sand grinder 6 arranged at the rear of the brick press 1 first crushes and grinds the raw materials into fine sand with uniform particle size, and the ground sand is transmitted to the top of the brick press 1 through the sand conveying track 5, and then falls into the scraping and feeding mechanism 3, at this time the sand stirring assembly 34 arranged in the mechanism is continuously started to continuously stir the internal sand.

[0060] Secondly, the feeding stage: the driving assembly 33 provides power support for the scraping and feeding mechanism 3, the double-acting cylinders 331 symmetrically arranged in the middle of the brick press 1 are started, when the piston rod is extended, the first support arm 332 is pushed to rotate forward around the front hinge point through the fastening block, and then the second support arm 333 connected at the tail drives the scraping and feeding mechanism 3 to move stably forward along the sliding guide rail 12 flush with the top surface of the lower die seat 2a in the middle of the brick press 1, the material supporting plate 311 at the bottom of the mechanism moves synchronously with the driving of the locking cylinder 312, when the scraping and feeding mechanism 3 pushes the uniformly stirred sand in the mechanism to the forming cavity of the lower die seat 2a and fills it, the feeding action is completed, at this time the piston rod of the double-acting cylinder 331 of the driving assembly 33 starts to retract, pulls the first support arm 332 and the second support arm 333 to rotate in the opposite direction, and drives the scraping and feeding mechanism 3 to start the retraction program.

[0061] Subsequently, the retraction phase: the scraping and feeding mechanism 3 retracts to the corresponding position of the waste sand discharge groove 2a1 of the lower mold base 2a, establishes linkage with the material supporting bottom plate 311 and drives it to move backward synchronously; during the retraction process, the triangular scraping boss 3222 at the bottom of the inner scraping plate 322 first directs the majority of the to-be-recovered material through the sand guiding slope 3111 at the front end of the material supporting bottom plate 311, and directs the flow back to the inside of the scraping and feeding mechanism 3, realizing the recycling and reuse of the main raw material. Due to the low precision requirement of the device on the cooperation of parts, there is a small amount of residual material that is not scraped back by the triangular scraping boss 3222. This part of residual material will be scraped off by the fixed scraping base plate 3212 at the bottom of the outer mounting plate 321 which is tightly attached to the lower mold base 2a. The waste sand recovery groove 3112 at the bottom of the front end of the material supporting bottom plate 311 cooperates with the fixed scraping base plate 3212 through the middle integrated limiting boss 3113 to form a waste material recovery channel with a predetermined width. The small amount of residual material scraped off is scraped into the waste material recovery channel for temporary storage. When the scraping and feeding mechanism 3 drives the material supporting bottom plate 311 to continue to retract to directly above the waste sand discharge groove 2a1, the unrecovered sand material temporarily stored in the waste material recovery channel will automatically fall into the waste sand discharge groove 2a1. At the same time, the bottom of the scraping part 325 is tightly attached to the top surface of the lower mold base 2a under the continuous downward pressure of the two sets of pressing mechanisms 324b, and the surface of the lower mold base 2a is scraped twice, which not only scrapes off most of the residual material on the surface of the lower mold base 2a, further ensures the flatness of the feeding area of the lower mold base 2a, but also corrects the flatness of the raw material in the forming cavity of the lower mold base 2a, and improves the subsequent pressing quality. When the scraping part 325 passes above the waste sand discharge groove 2a1, the residual material scraped off will directly fall into the waste sand discharge groove 2a1. The limiting support edges 2a2 integrally formed on the left and right sides near the middle of the waste sand discharge groove 2a1 have a top surface flush with the top surface of the lower mold base 2a, which can provide stable support for the scraping part 325 to avoid the scraping part 325 being pressed into the waste sand discharge groove 2a1 due to the pressure of the two sets of pressing mechanisms 324b. The scraping part 325 is finally retracted and reset smoothly with the scraping and feeding mechanism 3. After the scraping and feeding mechanism 3 is completely reset, the upper pressing mold 2b of the pressing brick module 2 moves downward to apply a predetermined pressure on the raw material in the forming cavity of the lower mold base 2a, and the pressing of the face brick body is completed.

[0062] Finally, the pressing and forming and recycling phase: after the scraping and feeding mechanism 3 completes the recycling, the upper pressing mold 2b in the pressing brick module 2 moves downward to close with the lower mold base 2a, applies a predetermined pressure on the sand material in the forming cavity, and compresses it into a face brick body. After the face brick body is formed and transported, the device is reset, the sand material conveying track 5 again conveys the ground sand material to the scraping and feeding mechanism 3, and the stirring assembly continues to stir, entering the next round of production cycle.
