Description

Technical Field

[0001] This invention belongs to the field of transportation operation technology, specifically relating to equipment for the production line operation of granite boards. Background Technology

[0002] Glamboard, also known as Glam polymer quartz board, typically involves several key production processes, including substrate pretreatment, surface lamination (such as fiberglass cloth bonding), coating roller coating, coating curing, stabilization and maintenance, and finished product stacking. Among these, the drying and curing process of the coating directly determines the surface hardness, weather resistance, dimensional stability, and overall production cycle time of the product, making it a core process affecting the final product quality and production efficiency.

[0003] Currently, tunnel-type drying ovens are widely used in the industry for coating curing. After coating, the boards are laid flat and continuously enter the drying oven, where solvent evaporation, cross-linking reaction, and chemical curing are completed under the action of a hot air circulation system. However, this technology has many limitations: First, tunnel-type drying ovens are bulky, typically tens of meters long, occupying a large amount of factory space, resulting in low space utilization and making it difficult to adapt to compact or high-density production line layouts; second, to ensure full curing of the coating, the boards need to stay in the oven for a long time, leading to a longer production cycle, limiting the overall capacity increase, and creating a bottleneck problem of "long process, low efficiency".

[0004] Furthermore, residual stress may still exist inside the board after high-temperature curing, and its physical properties are not yet fully stable. Traditional natural cooling or short-term static curing methods cannot effectively eliminate internal stress, easily leading to quality defects such as warping and cracking during subsequent processing or use, affecting product yield and end-application performance. During the curing stage, if conventional flat storage is used, the floor space occupied by each board is large, especially for large-area, thin-sized granite boards, whose planar projection area directly restricts storage density, resulting in wasted factory space and low logistics turnover efficiency. If an automated storage and retrieval system is used, higher requirements are placed on the lifting stroke, positioning accuracy, and structural strength of the palletizing robot, significantly increasing equipment investment and maintenance costs, further compressing production efficiency. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a production line equipment for granite boards to solve the problems existing in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is a glide board production line equipment for processing glide board coatings; it includes a coating drying component for curing the glide board coating; the coating drying component includes a drying chamber, and the drying chamber is provided with a support plate for placing the glide board, the support plate being able to move up and down in the vertical direction; by driving the support plate to move the glide board back and forth in the drying chamber, the glide board moves in the vertical direction, thereby extending the effective running path of the glide board in the drying environment, making full use of the vertical space of the drying chamber, increasing the residence time during the heat treatment process, and enhancing the coating curing effect.

[0007] Preferably, the coating drying component includes an annular guide rail for driving the support plate, the annular guide rail having a slider connected to the support plate; the annular guide rail includes a feeding section, a discharging section, and a circulation section connecting the feeding section and the discharging section; the support plate remains horizontal during operation in both the feeding section and the circulation section, ensuring that the coating on the granite plate remains stable during the drying and curing process, preventing the coating from flowing or becoming uneven, and ensuring the coating quality.

[0008] Furthermore, the coating drying component includes a limiting assembly, which includes a limiting block and a guide plate. The limiting block and the slider are rotatably connected via a rotating shaft. The limiting block has a first guide post and a second guide post, which are horizontally positioned. The annular guide rail is composed of a combination of a linear guide rail and a circular arc guide rail. The linear guide rail is used to guide the slider in a straight line in the vertical or horizontal direction, and the circular arc guide rail is disposed between adjacent linear guide rails to achieve a transitional connection for a 90° direction change.

[0009] The first guide post is located on the outer side of the arc guide rail, and the second guide post is located on the inner side of the arc guide rail. The guide plate is provided with a first slide groove, a second slide groove, a third slide groove, and a sliding cavity connecting the second slide groove and the third slide groove. The first slide groove and the third slide groove are connected by an arc slide groove. The radius of the arc slide groove is equal to the radius of the arc guide rail. The arc slide groove is tangent to the first slide groove and the third slide groove, respectively.

[0010] Furthermore, when the slider moves vertically along the linear guide rail, the first guide post slides into the first groove, and the second guide post slides into the second groove. When the slider enters the arc guide rail and begins to turn, the second guide post slides from the second groove into the sliding cavity. Simultaneously, under the coordinated limiting action of the first guide post, the first groove, and the rotating shaft, the first and second guide posts are kept in a horizontal state. Subsequently, the slider continues to move along the arc guide rail, and the first guide post moves from the first groove to the third groove, smoothly transitioning to the third groove along the slider's movement trajectory. The second guide post simultaneously slides from the sliding cavity into the third groove. When the slider leaves the arc guide rail and enters the horizontal linear guide rail, both the first and second guide posts are located in the third groove. Under the limiting action of the second guide post, the third groove, and the rotating shaft, the first and second guide posts remain horizontal during the movement of the sliding cavity, completing the vertical to horizontal turning process.

[0011] Furthermore, the limiting block has a third guide post and a fourth guide post, which are vertically arranged and symmetrically distributed on both sides of the rotation axis. The guide plate is provided with a vertically arranged fourth slide groove. When the slider moves vertically along the linear guide rail, the third guide post and the fourth guide post slide in the fourth slide groove, providing vertical guidance and lateral constraint for the limiting block. During the turning process of the slider through the arc guide rail, at least one of the third guide post and the fourth guide post is located in the fourth slide groove, continuously providing guidance and effectively suppressing the deflection tendency of the limiting block during the turning process, further ensuring that the first guide post and the second guide post always maintain a horizontal posture.

[0012] Furthermore, when a 180° directional change is required between two adjacent linear guide rails, a U-shaped transition structure is formed by symmetrically arranging two arc guide rails at the turning point to achieve a reverse switching of the slider's running direction. The arc guide rails are set in a mirror symmetric manner, and the bending radii of the two arc guide rails are equal, ensuring that the slider's movement trajectory is smooth and continuous during the turning process. Correspondingly, the guide plate and limiting component are also configured in a mirror symmetric manner along the turning center axis, so that during the process of the slider completing a 180° turn by passing through the two arc guide rails in sequence, the first guide post and the second guide post always maintain a horizontal posture under the cooperative limiting of each slide groove.

[0013] Furthermore, when the support plate is running in the feeding section and the circulation section, the limiting block and the support plate are fixedly connected. The first guide post, the second guide post, the third guide post and the fourth guide post set on the limiting block cooperate with the slides on the guide plate. Under the action of the slider, the limiting block directly limits and maintains the spatial posture of the support plate during the lifting and turning process. Throughout the entire process of the support plate moving in the vertical direction, turning through the arc guide rail and entering the horizontal section, the limiting block always provides posture constraints for the support plate, ensuring that the support plate remains horizontal throughout the entire running path. This prevents the coating on the plate from flowing, accumulating or having uneven thickness due to tilting, vibration or shaking, and ensures the consistency of the coating curing quality.

[0014] Furthermore, when the support plate is running in the unloading section, the limiting block and the support plate can switch between a fixed connection and a rotating connection; the unloading section is equipped with a steering mechanism, which, by switching the connection relationship to a rotating connection state and activating the steering mechanism, gradually switches the support plate from a horizontal conveying state to a vertical placement state; after the posture is flipped, the processed granite is arranged vertically with the support plate, which facilitates centralized picking and compact storage, effectively reduces the floor space occupied, and improves the space utilization efficiency at the end of the production line.

[0015] Furthermore, the limiting block has a through hole structure, including a coaxially arranged pivot hole and a circumferentially located slot; the support plate has a connecting shaft, one end of which is fixed to the support plate, and the other end of which slides axially through the pivot hole and extends to the outside of the limiting block, with a control plate at its end; a control spring is provided between the control plate and the limiting block, and a locking block adapted to the slot is provided on the connecting shaft; in normal operation, the control spring pushes the control plate, keeping the locking block embedded in the slot, and the limiting block and the support plate are in a rigid fixed connection state, ensuring that the support plate remains horizontal during lifting and turning; by pressing the control plate, the elastic force of the control spring is overcome, causing the connecting shaft to move axially inward, causing the locking block to disengage from the slot, at which point the circumferential constraint between the limiting block and the support plate is released, forming a relatively rotatable hinged connection state, providing a degree of freedom of movement for subsequent posture flipping.

[0016] Furthermore, the control board has a fitting groove; the steering mechanism includes a rotary motor and a linear moving component. The rotary motor is located on the moving end of the linear moving component, and the output end of the rotary motor has a push block adapted to the fitting groove. The linear moving component controls the push block to move towards the fitting groove, so that the push block is aligned and inserted into the fitting groove, and continues to push forward to press the control board, overcoming the elastic force of the control spring, driving the connecting shaft to move axially inward, so that the locking block disengages from the locking groove; subsequently, the rotary motor drives the push block to rotate in the fitting groove. Under the action of the fitting groove and the control board, the carrier plate gradually switches from a horizontal conveying state to a vertical placement state.

[0017] The main technical effects of this invention are reflected in the following aspects:

[0018] This invention abandons the traditional tunnel-type drying oven that relies on horizontal extension, and innovatively adopts a vertical reciprocating lifting and lowering cyclic operation mode. By setting up a ring guide rail system inside the drying chamber, the carrying plate drives the grate board to move up and down in multiple layers within a limited area. This allows the board to pass through high-temperature zones multiple times in vertical space, thereby significantly extending its residence time and effective operating path in the thermal environment without increasing the equipment's planar projection. This design achieves a space optimization strategy of "trading height for length," reducing the equipment's footprint and greatly improving the efficiency of factory space utilization. It is particularly suitable for modern production lines with limited space or high-density layouts, effectively solving the core pain points of traditional processes: "long process, low efficiency, and large footprint."

[0019] To address the issue of coating infill thickness and flow caused by tilting before complete curing of the glamping plate, this invention designs a precise two-dimensional guiding and limiting system. This system utilizes the coordinated action of the first and second horizontal guide posts on the limiting block and the first, second, and third sliding grooves and arc-shaped sliding grooves on the guide plate. When the slider rotates 90° or 180° along the arc-shaped guide rail, the guide posts are forced to remain horizontal, ensuring the stability of the support plate throughout lifting and turning. Simultaneously, the cooperation of the third and fourth vertical guide posts and the fourth sliding groove further suppresses lateral offset and torsional tendencies of the limiting block. This multi-directional constraint mechanism effectively eliminates attitude disturbances during movement, fundamentally avoiding quality defects caused by coating tilting or vibration, and significantly improving product surface flatness and yield.

[0020] This invention innovatively introduces a switchable connection state carrying mechanism in the unloading section. This allows the carrying plate to remain rigidly fixed during operation to ensure process stability, while switching to a hinged state for automatic flipping during the unloading stage. By controlling the cooperation of springs, locking blocks, and locking slots, a rigid connection between the limiting block and the carrying plate is maintained under normal conditions. When entering the unloading section, the push block of the steering mechanism inserts into the fitting slot and presses against the control plate, causing the locking block to disengage from the slot and releasing the circumferential constraint. Subsequently, the rotating motor drives the push block to rotate, smoothly flipping the carrying plate from a horizontal conveying state to a vertical placement state. This design allows finished grate boards to be arranged vertically, reducing the floor space of a single board by more than 70%, facilitating centralized picking and high-density storage, and significantly improving the space utilization efficiency and logistics automation level at the end of the production line.

[0030] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. In the embodiments, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art, etc., and therefore will not be described in detail in this embodiment.

[0031] The granite production line equipment provided by this invention is mainly used in the drying, curing, and stabilization conveying process of the coating on granite polymer quartz boards after coating. It is particularly suitable for continuous production lines with high requirements for space utilization, curing efficiency, and coating surface quality. However, it is not limited to this and can also be used in other similar or identical production processes, such as the manufacturing of non-metallic sheets with similar coating and thermosetting process requirements, such as artificial quartz stone slabs, ceramic thin slabs, glass fiber reinforced composite boards, and resin-based decorative boards. Its core technologies, such as vertical circulating conveying, multi-directional collaborative guiding and limiting, and variable posture bearing, can also be adapted to industrial scenarios that require extending the heat treatment path within a limited space, ensuring process stability, or achieving automatic end-of-line flipping and material handling.

[0032] Furthermore, as is common knowledge in this industry, the hot air circulation system inside the drying oven, the temperature sensor and PLC automatic control system, the servo motor or stepper motor transmission device driving the slider movement, the standard structural forms of linear and circular guide rails, the mechanical limit switches, and the photoelectric detection elements for position recognition, etc., mentioned above, are all common modules widely used in existing technologies. Meanwhile, the glamping board production line is also equipped with an automated loading and unloading system, palletizing equipment, and roller coating and brushing equipment required for glamping board coating production and processing. Since this is common knowledge, its principles and structure will not be elaborated further.

[0033] Example 1

[0034] The glamping board production line equipment disclosed in this embodiment mainly addresses the core problems existing in the traditional glamping board coating curing process, such as low equipment space utilization, short curing path, insufficient dwell time, and long production cycle.

[0035] Firstly, traditional tunnel-type drying ovens rely on horizontal linear conveying, necessitating a significant increase in oven length to extend curing time, resulting in substantial waste of factory space. This embodiment employs a vertical lifting and circulating operation mode. A ring-shaped guide rail system with loading, unloading, and circulation sections drives the support plate to move the grate board reciprocally up and down within the drying chamber. This design fully utilizes the vertical space of the factory, enabling the grate board to traverse multiple layers within a limited footprint, significantly extending its effective operating path and residence time in high-temperature environments. Compared to traditional flat-layout long tunnel ovens, this structure can achieve equivalent or even longer heat treatment strokes in a very small space, greatly improving space utilization efficiency, and is particularly suitable for modern production lines with limited space or high-density layouts.

[0036] Secondly, since the coating on the glam plate remains in a semi-fluid state during the curing process, any tilting or vibration can lead to quality defects such as coating flow and uneven thickness. Therefore, in this embodiment, the guiding limiting component, through the coordinated action of the first and second horizontal guide posts on the limiting block and the first, second, and third sliding grooves and sliding cavities on the guide plate, ensures that the carrying plate maintains a horizontal posture throughout the transition from the vertical running section to the horizontal running section (i.e., turning via the arc guide rail).

[0037] See Figure 1 , Figure 2Preferably, the assembly line equipment includes a coating drying component for curing the coating on the glide board. The coating drying component includes a drying chamber, the interior of which creates a controllable high-temperature environment to meet the process requirements of solvent evaporation and cross-linking reaction. The drying chamber is equipped with a support plate for placing the glide board, which can move vertically, causing the glide board to periodically move up and down within the drying chamber. By driving the support plate to reciprocate up and down within the drying chamber, the glide board moves vertically, extending its effective path in the drying environment, fully utilizing the vertical space of the drying chamber, increasing the residence time during heat treatment, and enhancing the coating curing effect. This vertical movement mode overcomes the limitations of traditional horizontal conveying, allowing the glide board to traverse high-temperature areas multiple times within a limited space, thus significantly extending its effective residence time in the thermal environment. Compared to fixed-path linear conveying, this reciprocating lifting method greatly increases the length of the heat treatment path and improves the processing capacity per unit space. Simultaneously, vertical movement fully utilizes the three-dimensional space of the factory, greatly reducing the equipment's floor area requirement and achieving efficient use of space resources. In addition, the lifting and lowering motion of the support plate not only extends the curing time, but also helps the circulation and disturbance of hot air inside the chamber, promotes the uniform distribution of the temperature field, avoids local overheating or insufficient curing, and further ensures the uniformity and consistency of coating curing.

[0038] Further, see Figure 3 , Figure 4 The coating drying component includes an annular guide rail for driving the support plate, enabling the support plate to circulate in an orderly and stable manner within the drying chamber. The annular guide rail has a slider connected to the support plate; the slider can roll or slide along a preset path on the guide rail. The slider is rigidly or flexibly connected to the support plate, allowing the slider's movement on the guide rail to directly drive the support plate synchronously. After receiving the plate in the loading section, the slider moves up and down along the circulation section. During this process, the support plate remains horizontal, ensuring the grate plate remains flat during curing, preventing quality defects such as flow, accumulation, or uneven thickness of the coating in the uncured state due to tilting or flipping. The annular guide rail includes a loading section, a unloading section, and a circulation section connecting the loading and unloading sections. The support plate remains horizontal during operation in both the loading and circulation sections, ensuring the grate plate coating remains stable during drying and curing, preventing flow or unevenness, and guaranteeing coating quality. This fundamentally ensures the physical stability of the coating during high-temperature curing, improving the consistency and yield of the product surface quality.

[0039] Further, see Figure 5 , Figure 6To ensure the stability of the bearing plate and the accuracy of its movement trajectory during the curing process of the glamping board, the system solves the problems of posture tilting and swaying that are prone to occur during the direction conversion of traditional lifting or circulating conveying systems, and ensures the flatness and uniformity of the coating in the high-temperature semi-fluid state. The coating drying component includes a limiting assembly, which includes a limiting block and a guide plate. The limiting block and the slider are rotatably connected by a rotating shaft. The limiting block has a first guide post and a second guide post, which are horizontally arranged. The annular guide rail is composed of a linear guide rail and a circular arc guide rail. The linear guide rail is used to guide the slider in a straight line in the vertical or horizontal direction. The circular arc guide rail is arranged between adjacent linear guide rails and is used to achieve a transition connection for 90° direction conversion. The first guide post is located outside the circular arc guide rail, and the second guide post is located inside the circular arc guide rail. The guide plate is provided with a first slide groove, a second slide groove, a third slide groove, and a sliding cavity connecting the second slide groove and the third slide groove. The first slide groove and the third slide groove are connected by a circular arc slide groove. The radius of the circular arc slide groove is equal to the radius of the circular arc guide rail, and the circular arc slide groove is tangent to the first slide groove and the third slide groove, respectively.

[0040] When the slider moves vertically along the linear guide rail, the first guide post slides into the first groove, and the second guide post slides into the second groove. When the slider enters the arc guide rail and begins to turn (90° turn), the second guide post slides from the second groove into the sliding cavity. Simultaneously, under the synergistic limiting action of the first guide post, the first groove, and the rotating shaft, combined with the fulcrum action of the rotating shaft, a stable lever limiting structure is formed, maintaining the first and second guide posts in a horizontal state. Even if the slider itself rotates on the arc guide rail, the limiting block can still maintain the horizontal position of the mounting plate installed on it through this synergistic mechanism, effectively preventing the coating from flowing or accumulating due to tilting of the plate during turning. Subsequently, the slider continues to move along the arc guide rail, and the first guide post moves from the first groove to the third groove, smoothly transitioning to the third groove along the slider's movement trajectory. The second guide post simultaneously slides from the sliding cavity into the third groove.

[0041] After the slider disengages from the circular arc guide rail and enters the horizontal linear guide rail, both the first guide post and the second guide post are located in the third slide groove. With the limiting cooperation of the second guide post, the third slide groove and the rotating shaft, the first guide post and the second guide post remain horizontal during the movement of the sliding cavity, completing the vertical to horizontal turning process.

[0042] To further enhance system stability, the limiting block has a third guide post and a fourth guide post, which are vertically arranged and symmetrically positioned on both sides of the rotation axis. The guide plate has a vertically arranged fourth groove. When the slider moves vertically along the linear guide rail, the third and fourth guide posts slide within the fourth groove, providing vertical guidance and lateral constraint to the limiting block. During the slider's turning motion along the arc guide rail, at least one of the third and fourth guide posts remains within the fourth groove, continuously providing guidance and effectively suppressing the limiting block's deflection tendency during turning, further ensuring that the first and second guide posts always maintain a horizontal orientation.

[0043] Example 2

[0044] This embodiment, based on Embodiment 1, further expands the structural adaptability and operational flexibility of the ring guide rail system, targeting application scenarios requiring 180° reverse rotation in specific process layouts. Details are as follows:

[0045] See Figure 3 When a 180° directional change is required between two adjacent linear guide rails (e.g., to achieve a close parallel arrangement of up and down channels in a vertical lifting loop), traditional single-segment circular arc guide rails are difficult to complete large-angle turns. Therefore, this embodiment uses two symmetrically arranged circular arc guide rails at the turning point to form a U-shaped transition structure, enabling reverse switching of the slider's running direction. The two circular arc guide rails are arranged in a mirror-symmetrical manner with respect to the turning center axis, each bent into a 90° arc, connecting end to end to form a complete semi-circular (180°) transition path. The circular arc guide rails are set in a mirror-symmetrical manner, and the bending radii of the two circular arc guide rails are equal, ensuring a smooth and continuous movement trajectory of the slider during the turning process. Correspondingly, the guide plate and limiting components are also arranged in a mirror-symmetrical manner along the turning center axis, so that during the process of the slider sequentially passing through the two circular arc guide rails to complete a 180° turn, the first guide post and the second guide post always maintain a horizontal posture under the cooperative limiting of each slide groove.

[0046] The guide plate's sliding system includes a first sliding groove, a second sliding groove, a third sliding groove, a sliding cavity, an arc-shaped sliding groove, and a fourth sliding groove—all arranged in a mirror-symmetrical configuration along the steering center axis. Specifically, in the first half of the U-shaped transition (the first 90° turn), the first guide post enters the third sliding groove from the first sliding groove via the arc-shaped sliding groove, and the second guide post enters the sliding cavity from the second sliding groove. When entering the second half (the second 90° turn), the symmetrical structure of the guide plate allows the first and second guide posts to repeat the aforementioned movement path in reverse, that is, the first guide post returns from the third sliding groove to the first sliding groove via the arc-shaped sliding groove on the other side, and the second guide post returns from the sliding cavity to the second sliding groove.

[0047] Throughout the entire 180° turn, the first and second guide posts remain horizontal under the coordinated limiting action of the various grooves and the rotating shaft. Even if the overall movement direction of the slider is completely reversed, the limiting block, through the cooperation of its symmetrically arranged guide posts and grooves, still forces it to maintain its own posture, thereby ensuring that the connected support plate always remains horizontal. This design effectively avoids the tilting of the plate caused by large-angle turns and prevents defects such as coating flow, accumulation, or edge thickening due to gravity in the uncured state.

[0048] Furthermore, the sliding engagement of the third and fourth guide posts within the fourth groove also plays a continuous role in the symmetrical structure. Throughout the entire U-turn, at least one vertical guide post remains within the fourth groove, providing stable vertical guidance and lateral constraint for the limiting block, suppressing its torsional tendency under complex trajectories, and further enhancing the structural rigidity and operational reliability of the system.

[0049] Example 3

[0050] This embodiment, based on Embodiments 1 and 2, further innovates the connection method between the support plate and the limiting component to meet the differentiated requirements of the glamping board for spatial posture and operational stability at different process stages. This solution not only ensures the absolute horizontal stability of the support plate during curing but also achieves automatic posture flipping during the unloading stage, significantly improving the space utilization efficiency and logistics automation level at the end of the production line.

[0051] See Figure 7 , Figure 8 When the support plate is running in the feeding section and the circulation section, in order to ensure that the coating does not suffer from defects such as flow, accumulation or uneven thickness due to changes in posture during high-temperature curing, the limiting block and the support plate are fixedly connected. The first guide post, second guide post, third guide post and fourth guide post set on the limiting block cooperate with the sliding grooves on the guide plate. Under the action of the slider, the limiting block directly limits and maintains the spatial posture of the support plate during lifting and turning. Throughout the entire process of the support plate moving in the vertical direction, turning through the arc guide rail and entering the horizontal section, the limiting block always provides posture constraints for the support plate, ensuring that the support plate remains horizontal throughout the entire running path, preventing the coating on the plate from flowing, accumulating or uneven in thickness due to tilting, vibration or shaking, and ensuring the consistency of coating curing quality.

[0052] In the unloading section, the process requirements change: to facilitate subsequent part retrieval, stacking, and storage, the flat-lying grate boards need to be converted to a vertically arranged state to reduce the floor space occupied by each board and improve space utilization. Therefore, when the support plate is running in the unloading section, the limiting block and the support plate can switch between a fixed connection and a rotating connection. The unloading section is equipped with a steering mechanism; by switching the connection relationship to a rotating connection state and activating the steering mechanism, the support plate is gradually switched from a horizontal conveying state to a vertical placement state. After the posture flip is completed, the processed grate boards are arranged vertically along with the support plate, facilitating centralized part retrieval and compact storage, effectively reducing the floor space occupied and improving the space utilization efficiency at the end of the production line.

[0053] The specific structure is as follows: The limiting block has a through hole structure, including a coaxially arranged rotating shaft hole and a circumferential slot; the bearing plate has a connecting shaft, one end of which is fixed to the bearing plate, and the other end of which slides axially through the rotating shaft hole and extends to the outside of the limiting block, with a control plate at its end; a control spring is provided between the control plate and the limiting block, and a locking block adapted to the slot is provided on the connecting shaft; in normal operation, the control spring pushes the control plate, keeping the locking block embedded in the slot, and the limiting block and the bearing plate are in a rigid fixed connection state, ensuring that the bearing plate remains horizontal during lifting and turning; by pressing the control plate, the elastic force of the control spring is overcome, causing the connecting shaft to move axially inward, causing the locking block to disengage from the slot. At this time, the circumferential constraint between the limiting block and the bearing plate is released, forming a hinged connection state that can rotate relative to each other, providing freedom of movement for subsequent posture flipping. The control panel has a fitting slot; the steering mechanism includes a rotary motor and a linear moving component. The rotary motor is located on the moving end of the linear moving component, and the output end of the rotary motor has a push block adapted to the fitting slot. The linear moving component controls the push block to move towards the fitting slot, so that the push block is aligned and inserted into the fitting slot, and continues to push forward to press the control panel, overcoming the elastic force of the control spring, driving the connecting shaft to move axially inward, so that the locking block disengages from the locking slot; subsequently, the rotary motor drives the push block to rotate in the fitting slot, and under the action of the fitting slot and the control panel, the carrier plate gradually switches from a horizontal conveying state to a vertical placement state.

[0054] When the steering mechanism operates, it consists of a linear moving component and a rotary motor mounted on its moving end. The output end of the rotary motor has a push block. The linear moving component drives the push block to move precisely, aligning it with and inserting it into the fitting groove of the control plate on the limit block. Subsequently, the push block continues to advance, pressing the control plate through the fitting groove, overcoming the spring force of the control spring, and causing the axial movement of the connecting axis limit block, thereby disengaging the locking block from the groove and releasing the circumferential constraint. At this point, the limit block and the carrier plate are only hinged together through the connecting shaft, giving the carrier plate the freedom to rotate around the connecting shaft axis. Immediately afterwards, the rotary motor starts, driving the push block to rotate within the fitting groove. The push block drives the control plate and the connecting shaft fixed to it to rotate synchronously through the fitting groove, thereby driving the carrier plate to gradually flip from a horizontal conveying state to a vertical placement state. The flipping angle can be precisely controlled to 90°, turning the plate from flat to upright. After flipping, the glide boards are arranged vertically, which facilitates the centralized picking of parts by robotic arms or manual labor, while significantly reducing the storage floor space. It is especially suitable for dense stacking and logistics turnover of large-area, thin glide boards.

Claims

1. A continuous production line equipment for glide board coating processing; characterized in that, The device includes a coating drying component for curing the coating on a glide board. The coating drying component includes a drying chamber containing a support plate for placing the glide board. The support plate is capable of vertical lifting and lowering. By driving the support plate, the glide board reciprocates within the drying chamber, moving vertically and extending its effective path in the drying environment. This fully utilizes the vertical space of the drying chamber, increases the residence time during heat treatment, and enhances the coating curing effect. The coating drying component includes an annular guide rail for driving the support plate. The annular guide rail has a slider, which is connected to the support plate. The annular guide rail includes a feeding section, a discharging section, and a circulation section connecting the feeding section and the discharging section. The support plate remains horizontal during operation in both the feeding section and the circulation section to ensure that the coating on the granite plate remains stable during the drying and curing process, preventing the coating from flowing or becoming uneven, and ensuring the coating quality. The coating drying component includes a limiting assembly, which includes a limiting block and a guide plate. The limiting block and the slider are rotatably connected by a rotating shaft. The limiting block has a first guide post and a second guide post, which are horizontally arranged. The annular guide rail is composed of a linear guide rail and a circular arc guide rail. The linear guide rail is used to guide the slider in a straight line in the vertical or horizontal direction. The circular arc guide rail is arranged between adjacent linear guide rails and is used to achieve a transition connection for 90° direction conversion. The first guide post is located outside the circular arc guide rail, and the second guide post is located inside the circular arc guide rail. The guide plate is provided with a first slide groove, a second slide groove, a third slide groove, and a sliding cavity connecting the second slide groove and the third slide groove. The first slide groove and the third slide groove are connected by a circular arc slide groove. The radius of the circular arc slide groove is equal to the radius of the circular arc guide rail, and the circular arc slide groove is tangent to the first slide groove and the third slide groove, respectively. The limiting block has a third guide post and a fourth guide post, which are vertically arranged and symmetrically distributed on both sides of the rotation axis. The guide plate has a fourth sliding groove that is vertically arranged. When the slider moves vertically along the linear guide rail, the third guide post and the fourth guide post slide in the fourth sliding groove, providing vertical guidance and lateral constraint for the limiting block. During the turning process of the slider through the arc guide rail, at least one of the third guide post and the fourth guide post is located in the fourth sliding groove, continuously providing guidance and effectively suppressing the deflection tendency of the limiting block during the turning process, further ensuring that the first guide post and the second guide post always maintain a horizontal posture.

2. The granite production line equipment as described in claim 1, characterized in that, When the slider moves vertically along the linear guide rail, the first guide post slides into the first groove, and the second guide post slides into the second groove. When the slider enters the arc guide rail and begins to turn, the second guide post slides from the second slide groove into the sliding cavity. At the same time, under the cooperative limiting effect of the first guide post, the first slide groove and the rotating shaft, the first guide post and the second guide post are kept in a horizontal state. Subsequently, the slider continues to move along the arc guide rail, the first guide post moves from the first slide groove to the third slide groove, and smoothly transitions to the third slide groove along the slider's movement trajectory, while the second guide post simultaneously slides from the sliding cavity into the third slide groove; After the slider disengages from the circular arc guide rail and enters the horizontal linear guide rail, both the first guide post and the second guide post are located in the third slide groove. With the limiting cooperation of the second guide post, the third slide groove and the rotating shaft, the first guide post and the second guide post remain horizontal during the movement of the sliding cavity, completing the vertical to horizontal turning process.

3. The granite production line equipment as described in claim 2, characterized in that, When a 180° direction change is required between two adjacent linear guide rails, a U-shaped transition structure is formed by symmetrically arranging two circular arc guide rails at the turning point to achieve the reverse switching of the slider running direction. The circular arc guide rails are set in a mirror symmetrical manner, and the two circular arc guide rails have the same bending radius, ensuring that the slider's movement trajectory is smooth and continuous during the turning process; Correspondingly, the guide plate and limiting assembly are also arranged in a mirror symmetrical configuration along the steering center axis, so that as the slider completes a 180° turn by passing through two arc guide rails in sequence, the first guide post and the second guide post always maintain a horizontal posture under the cooperative limiting of each slide groove.

4. The granite production line equipment as described in claim 3, characterized in that, When the support plate is running in the feeding section and the circulation section, the limiting block and the support plate are fixedly connected. The first guide post, the second guide post, the third guide post and the fourth guide post set on the limiting block cooperate with each slide groove on the guide plate. Under the drive of the slider, the limiting block directly limits and maintains the spatial posture of the support plate during the lifting and turning process. Throughout the entire process of the carrier plate moving vertically, turning via the arc guide rail, and entering the horizontal section, the limiting block always provides attitude constraints on the carrier plate, ensuring that the carrier plate remains horizontal throughout the entire running path. This prevents the coating on the glide plate from flowing, accumulating, or becoming uneven in thickness due to tilting, vibration, or shaking, thus ensuring the consistency of the coating curing quality.

5. The granite production line equipment as described in claim 4, characterized in that, When the support plate is running in the feeding section, the limiting block and the support plate can switch between fixed connection and rotational connection; The feeding section is equipped with a steering mechanism. By switching the connection relationship to a rotational connection state and activating the steering mechanism, the bearing plate is gradually switched from a horizontal conveying state to a vertical placement state. After the orientation is flipped, the processed grate plates are arranged vertically along with the support plate, which facilitates centralized picking and compact storage, effectively reducing the floor space and improving the space utilization efficiency at the end of the production line.

6. The granite production line equipment as described in claim 5, characterized in that, The limiting block has a through hole structure, including a coaxially arranged rotating shaft hole and a circumferentially located slot; the bearing plate has a connecting shaft, one end of which is fixed to the bearing plate, and the other end of which slides axially through the rotating shaft hole and extends to the outside of the limiting block, and has a control plate at its end; a control spring is provided between the control plate and the limiting block, and a locking block adapted to the slot is provided on the connecting shaft; Under normal operating conditions, the control spring pushes the control plate to keep the card block embedded in the card slot, and the limit block and the bearing plate are in a rigid fixed connection state, ensuring that the bearing plate remains horizontal during lifting and turning. By pressing the control plate, the elastic force of the control spring is overcome, causing the connecting shaft to move axially inward, so that the locking block is disengaged from the slot. At this time, the circumferential constraint between the limiting block and the bearing plate is released, forming a hinged connection state that can rotate relative to each other, providing a degree of freedom of movement for subsequent posture flipping.

7. The granite production line equipment as described in claim 6, characterized in that, The control board has a fitting groove; The steering mechanism includes a rotary motor and a linear moving component. The rotary motor is disposed on the moving end of the linear moving component, and the output end of the rotary motor is provided with a push block adapted to the fitting groove. The linear moving component controls the pusher to move towards the fitting groove, aligning and inserting the pusher into the fitting groove. It continues to push forward to press the control plate, overcoming the elastic force of the control spring, and driving the connecting shaft to move axially inward, causing the locking block to disengage from the slot. Subsequently, the rotary motor drives the pusher to rotate within the fitting groove. Under the action of the fitting groove and the control plate, the carrier plate gradually switches from a horizontal conveying state to a vertical placement state.
