Description

Technical Field

[0001] The present invention relates to the technical field of sheet processing equipment, in particular to an automatic plate feeding and discharging machine for a hot press with a narrow layer spacing, and a usage method applied to the automatic plate feeding and discharging machine for a hot press with a narrow layer spacing. Background Art

[0002] In modern industrial production, as an important processing equipment, hot presses are widely used in multiple fields, such as wood processing, plastic molding, metal pressing, etc. In the production process of a hot press, the feeding of sheet materials and the discharging of finished plates are crucial, and the operation efficiency and quality directly affect the efficiency of the entire production process and the quality of products.

[0003] Currently, when the existing sheet material hot press feeder performs the feeding operation on the hot press, it generally adopts a method of pushing out the hot-pressed finished sheet material while feeding the sheet core to be hot-pressed. This design concept aims to improve the continuity of production, reduce the idle time of the equipment, and thus enhance the overall production efficiency. Moreover, in order to better connect this process, the existing sheet material hot press feeder is also designed with a material retaining mechanism, whose function is to retain the sheet core in the hot press after pushing in the sheet core to be hot-pressed, so as to perform subsequent hot pressing processing procedures.

[0004] However, through actual production verification, this traditional design method has many insurmountable problems. First, during the simultaneous operation of pushing and feeding, since it is necessary to coordinate the actions of pushing out the finished sheet material and feeding the sheet core to be hot-pressed at the same time, in order to avoid interference between the two, the plate spacing must be designed to be large enough. In the case of a limited space in the hot press, a larger plate spacing means that the number of sheet cores that can be accommodated in a single hot pressing process within the same height layer spacing is significantly reduced, which directly leads to limited processing times per unit time of the equipment, low production efficiency, and inability to meet the requirements of large-scale and high-efficiency production in modern industry.

[0005] Secondly, the simultaneous operation of pushing and feeding brings great inconvenience to the cleaning and maintenance of the equipment. During the hot pressing process, impurities, waste materials, etc. will inevitably remain on the hot press table. Due to the synchronization of the pushing and feeding actions, workers cannot effectively clean the hot press table in time after the hot pressing process. In this regard, if the remaining impurities cannot be removed in time, they may be mixed between the sheet materials during the next hot pressing process, affecting the bonding degree and forming quality of the sheet materials, thereby causing defects in the products, reducing the overall quality stability of the products, and affecting the market competitiveness of the products.

[0006] In summary, the existing feeding machines for sheet hot presses have obvious defects in design and operation methods, and it is difficult to meet the dual requirements of modern industrial production for improving production efficiency and ensuring product quality. Therefore, there is an urgent need for a new type of sheet feeding and discharging equipment that can effectively solve the above problems and achieve efficient and high-quality hot pressing processing production. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides an automatic sheet feeding and discharging machine for a narrow layer spacing hot press, which separates the operations of pushing out and pushing in the sheet. The pushing plate structure is compact and is adapted to the placement of sheets with narrow spacing, improving the quantity and efficiency of sheets processed by hot pressing at one time. Moreover, the frame is designed to be movable. After pushing out the finished sheet, the table surface of the hot press can be cleaned to ensure the quality of subsequent processing and improve the stability of the product.

[0008] The present invention also provides a method of using the above-mentioned automatic sheet feeding and discharging machine for a narrow layer spacing hot press.

[0029] In the description of the present invention, each hydraulic cylinder is only one solution, and mechanical telescopic devices such as air cylinders have the same function as hydraulic cylinders.

[0030] In modern industrial production, as an important processing equipment, hot presses are widely used in multiple fields, such as wood processing, plastic molding, metal pressing, etc. In the production process of hot presses, the feeding of sheet materials and the discharging of finished sheets are crucial, and the efficiency and quality of their operations directly affect the efficiency of the entire production process and the quality of products.

[0031] Currently, when the existing sheet material hot press feeder performs the feeding operation on the hot press, it generally adopts a method of feeding the sheet core to be hot pressed while pushing out the finished sheet after hot pressing. This design concept aims to improve the continuity of production, reduce the idle time of the equipment, and thus improve the overall production efficiency. Moreover, in order to better connect this process, the existing sheet material hot press feeder is also designed with a material retaining mechanism, whose function is to retain the sheet core in the hot press after pushing in the sheet core to be hot pressed for subsequent hot pressing processing procedures.

[0032] However, through actual production verification, this traditional design method has many problems that are difficult to overcome. First of all, during the simultaneous operation of pushing and feeding, since it is necessary to coordinate the actions of pushing out the finished sheet and feeding the sheet core to be hot pressed at the same time, in order to avoid interference between the two, the distance between the sheets must be designed to be large enough. In the case of limited space in the hot press, a larger distance between the sheets means that the number of sheet cores that can be accommodated for single - time hot pressing processing within the same height layer spacing is significantly reduced, which directly results in limited processing times of the equipment per unit time, low production efficiency, and inability to meet the requirements of large - scale and high - efficiency production in modern industry.

[0033] Secondly, the way of simultaneous pushing and feeding operations brings great inconvenience to the cleaning and maintenance of the equipment. During the hot pressing process, some impurities and waste materials will inevitably remain on the tabletop of the hot press. Due to the synchronization of the pushing and feeding actions, after the hot pressing process is completed, workers cannot effectively clean the tabletop of the hot press in a timely manner. In this regard, if the remaining impurities cannot be removed in time, they may be mixed between the sheet materials during the next hot pressing process, affecting the fitting degree and forming quality of the sheet materials, thereby causing defects in the products, reducing the overall quality stability of the products, and affecting the market competitiveness of the products.

[0034] In summary, the existing sheet material hot press feeder has obvious defects in design and operation mode, and it is difficult to meet the dual requirements of modern industrial production for improving production efficiency and ensuring product quality. Therefore, there is an urgent need for a new type of sheet material feeding and discharging equipment that can effectively solve the above problems and achieve high-efficiency and high-quality hot pressing production.

[0035] For this reason, as Figures 1 to 5As shown in the figure, the automatic plate feeding and discharging machine for a narrow layer spacing hot press proposed by the present invention includes a frame 100, a first push rod 231 assembly 200 connected to the frame 100, a second push rod assembly 400 connected to the frame 100, and a position changing assembly 300 connected to the frame 100 and used to drive the frame 100 to move along one side towards or away from the hot press 500. Among them, after the position changing assembly 300 drives the frame 100 to move along one side towards the hot press 500 to the in-place position, the frame 100 is at the working station. Specifically, the first push rod 231 assembly 200 includes a first lifting drive assembly 210, a first horizontal drive assembly 220, and a multi-layered first push frame 230. The first lifting drive assembly 210 is used to drive the first push frame 230 to align with the feeding position of the hot press 500, and the first horizontal drive assembly 220 is used to drive the first push frame 230 into the hot press 500 to push out the finished plate. Optionally, after the finished plate is pushed out, when the position changing assembly 300 drives the frame 100 to move along one side away from the hot press 500 to the in-place position, the frame 100 is at the cleaning station. At this time, the worker can clean the tabletop of the hot press 500. Further, the frame 100 is provided with a multi-layered carrier 110. For example, the carrier 110 has a supporting plane to support the plate to be processed. For another example, the carrier 110 is provided with supporting rollers to roll and support the plate to be processed, so as to facilitate the plate to be processed to enter and slide out of the frame 100. The second push rod assembly 400 includes a second lifting drive assembly 410, a second horizontal drive assembly 420, and a multi-layered second push frame 430. The second push frame 430 can sink into the carrier 110 to allow the plate to be processed to enter the carrier 110. The second lifting drive assembly 410 is used to drive the second push frame 430 to align with the feeding position of the hot press 500, and the second horizontal drive assembly 420 is used to drive the plate to be processed into the hot press 500.It should be noted that the multi-layer structure support bracket 110 provided on the frame 100 provides a stable and orderly space for storing the plates to be processed. Moreover, the first lifting drive assembly 210 drives the first push frame 230 to align with the feeding position of the hot press 500, and then the first horizontal drive assembly 220 pushes it into the hot press 500, which can accurately push out the finished plates located in the hot press 500, realizing the automated and precise operation of pushing out the finished plates. Optionally, after pushing out the finished plates, the frame 100 is moved to the cleaning station by the position-changing assembly 300, providing space for workers to clean the tabletop of the hot press 500. This design ingeniously solves the problem that the traditional equipment cannot effectively clean the tabletop of the hot press 500, ensuring the cleanliness of the tabletop of the hot press 500 and avoiding the influence of impurities on subsequent processing. In addition, after the hot press 500 is cleaned, the position-changing assembly 300 moves the frame 100 to the working station. Since the second push frame 430 can sink into the support bracket 110, the plates to be processed can conveniently enter the support bracket 110. Then, the second lifting drive assembly 410 drives the second push frame 430 to align with the feeding position of the hot press 500, and the second horizontal drive assembly 420 pushes the plates to be processed into the hot press 500, realizing the automated operation of pushing in the plates to be processed. Overall, through reasonable structural layout and design, the separate operations of pushing out the finished plates and pushing in the plates to be processed are realized, making the push plate structure more compact, effectively adapting to the placement method of the plates to be processed with narrow spacing, increasing the number of plates to be processed in a single hot pressing process under the same height condition, greatly improving the production efficiency. At the same time, the movable frame 100 can leave a cleaning passage after pushing out the finished plates, facilitating workers to clean the tabletop of the hot press 500, avoiding the influence of impurities on the quality of subsequent processing, ensuring the stability and consistency of the product quality, and enhancing the overall quality and market competitiveness of the product.

[0036] In some embodiments of the present invention, since both the second push frame 430 and the first push frame 230 have lifting structures, such as Figures 1 to 3As shown, the second pusher 430, the supporting bracket 110, and the first pusher 230 can be in the same horizontal position. Specifically, the first pusher 230 is provided with a plurality of first push rods 231 arranged at intervals in the vertical direction, the second pusher 430 is provided with a plurality of second push rods arranged at intervals in the vertical direction, and the supporting bracket 110 is provided with a plurality of supporting rollers arranged at intervals in the vertical direction. At the same structural position, the first push rod 231 and the second push rod can be lower than or flush with the upper ends of the supporting rollers. From the perspective of structural coordination, the three being in the same horizontal position makes the entire process of feeding and discharging the board more smooth and stable. During the process of loading the board to be processed onto the supporting bracket 110 and then pushing it into the hot press 500, the smoothness of the board transfer can be ensured, and problems such as board shaking and jamming caused by height differences or position deviations can be reduced, improving the reliability of the equipment operation. At the same time, this design is beneficial to maximizing the realization of the structural design with a narrow layer distance. For example, at the same horizontal position, the first pusher 230 surrounds the outside of the supporting bracket 110 to be suitable for moving outwards to push out the finished board of the hot press 500, and the second pusher 430 surrounds part of the supporting bracket 110 to be suitable for protruding from the supporting bracket 110 to push out the board to be processed at an appropriate time. In this regard, the supporting bracket 110 of the present application can support the board to be processed with a relatively narrow layer distance. Compared with the existing board feeding and discharging machine of the same height, the supporting bracket 110 can place 1 to 2 times more board materials, adapting to the processing equipment of the hot press 500 with the same narrow layer distance.

[0037] In some embodiments of the present invention, the first lifting drive assembly is directly connected to and drives the first pusher to move in the vertical direction. For example, a cylinder or a linear motor is installed on the frame, and the drive shaft of the cylinder or the linear motor is fixedly connected to the first pusher. For another example, a rotary motor is installed on the frame, and a transmission mechanism is provided between the drive shaft of the rotary motor and the first pusher to drive the first pusher to move linearly (not shown in the figure). Referring again to Figure 2 and Figure 3, in some embodiments of the present invention, the first lifting drive assembly 210 is connected to and drives the frame 100 and the first pushing frame 230 to move together. For example, an external power can be used to drive the entire frame 100 to move upward to drive the first pushing frame 230 to align with the feeding position of the hot press 500. After the finished board is pushed out by the first pushing frame 230, the external power then drives the entire frame 100 to move downward to drive the supporting bracket 110 to align with the tabletop of the hot press 500. Then, the second pushing frame 430 moves upward to align with the feeding position of the hot press 500 to push out the board to be processed. This provides more flexibility and adaptability for the operation of the equipment. When only driving the first pushing frame 230 to move in the vertical direction, the lifting position of the first pushing frame 230 can be controlled more precisely, enabling it to accurately align with the feeding position of the hot press 500, improving the accuracy and stability of the pushing. When driving the frame 100 and the first pushing frame 230 to move together, the overall movement state of the equipment can be better coordinated. In some complex working conditions, such as when there are certain deviations in the installation foundation of the equipment or overall adjustment is required, this joint lifting movement can better adapt to the actual situation, ensure that the equipment is always in the best working state, thereby improving the versatility and practicality of the equipment, and reducing equipment failures and production problems caused by environmental factors or installation issues.

[0038] Specifically, referring again to Figure 2 and Figure 3, in some embodiments of the present invention, the displacement assembly 300 includes a horizontal moving member 310. The frame 100 is slidably disposed on the horizontal moving member 310 in the vertical direction. The first lifting drive assembly 210 includes a first lifting drive hydraulic cylinder 211. The cylinder body of the first lifting drive hydraulic cylinder 211 is fixedly connected to the frame 100. The drive shaft of the first lifting drive hydraulic cylinder 211 can extend outwards and push downwards against the horizontal moving member 310 to drive the frame 100 to move upwards. It is easy to understand that by realizing the horizontal movement of the frame 100 through the horizontal moving member 310, the switching position of the frame 100 between the working station and the cleaning station can be accurately controlled, ensuring the accuracy and stability of the movement of the frame 100. And the first lifting drive hydraulic cylinder 211 is fixedly connected to the frame 100 through the cylinder body. Through the unique design of pushing down the horizontal moving member 310 by the drive shaft, the lifting movement of the frame 100 is made more stable and controllable. On the one hand, a large force is generated on the horizontal moving member 310 at the moment when the first lifting drive hydraulic cylinder 211 pushes, which can press down the horizontal moving member 310 to a certain extent to make it stop, and a large static friction force needs to be overcome to start again, so that its sliding can be avoided. On the other hand, the shaking and vibration of the frame 100 during the lifting process can be effectively reduced, avoiding unnecessary impacts and damages to other components of the equipment and prolonging the service life of the equipment. Optionally, the horizontal moving member is a slider, and a guide rail (not shown in the figure) cooperating with the slider is provided on the ground. In some manual applications, the frame 100 is directly pushed by hand. In some automated applications, the slider can be driven to move along the length direction of the guide rail through a hydraulic motor screw structure (not shown in the figure). In some embodiments of the present invention, as Figures 1 to 3 shown, the horizontal moving member 310 is a roller, which can greatly reduce the friction force during the horizontal movement of the frame 100, making the movement of the frame 100 smoother and lighter. At this time, the roller has a wheel frame, and a vertically arranged guide rod 311 is fixed on the wheel frame. A vertically arranged guide sleeve 212 is fixed on the frame 100. The drive shaft of the first lifting drive hydraulic cylinder 211 is fixedly connected to the wheel frame. When the first lifting drive hydraulic cylinder 211 operates, it drives the guide sleeve 212 to slide up and down relative to the guide rod 311. Compared with other traditional sliding friction methods, the use of rollers reduces energy loss, improves the operating efficiency of the equipment. At the same time, the service life of the rollers is relatively long, and the maintenance cost is low, and good performance can be maintained during long-term use. In addition, the installation and adjustment of the rollers are relatively simple, and the position and spacing of the rollers can be adjusted according to actual needs to adapt to different working environments and equipment installation requirements, further enhancing the flexibility and adaptability of the equipment. For example, the roller can have a braking function, and a track (not shown in the figure) restricting the linear movement of the roller can also be provided on the ground.

[0039] Refer again to Figure 4, in some embodiments of the present invention, the first pusher 230 includes a plurality of first push rods 231 arranged at intervals in the vertical direction. A claw seat 2311 is provided at the end of the first push rod 231. A tension spring 2313 and a rotating push rod 2312 are provided on the claw seat 2311. The plate to be processed can flatten the rotating push rod 2312 and enter the hot press 500. The tension spring 2313 is connected and drives the rotating push rod 2312 to be vertically arranged and protrude upward from the first push rod 231. It should be noted that the cooperative design of the claw seat 2311, the tension spring 2313 and the rotating push rod 2312 realizes a more intelligent and flexible pushing function. The tension spring 2313 is connected and drives the rotating push rod 2312 to be vertically arranged and protrude upward from the first push rod 231. This structure can keep the rotating push rod 2312 erected in the normal state, and can effectively and reliably push the finished plate in the hot press 500 out of the hot press 500. With a slight force, the rotating push rod 2312 can be flattened, and the plate to be processed can flatten the rotating push rod 2312 under the push of the second pusher 430 and smoothly enter the hot press 500, ensuring the smoothness and accuracy of the pushing process, and improving the working efficiency and reliability of the equipment. It can be understood that the plate to be processed is loaded on the side of the supporting bracket 110 away from the rotating push rod 2312. To a certain extent, the rotating push rod 2312 can prevent the plate to be processed from sliding into the supporting bracket 110 excessively and slipping out. For example, a tension spring 2313 with a larger pulling force can be selected. Only under the pushing action of the second pusher 430 can the plate to be processed smoothly flatten the rotating push rod 2312 and enter the hot press 500.

[0040] It should be noted that if the finished plate in the hot press 500 does not warp and deform, the claw seat 2311 may not be provided. And referring again to Figure 7 , in some embodiments of the present invention, a pushing rubber plate 2314 is provided at the end of the first push rod 231. The pushing rubber plate 2314 is sleeved on the first push rod 231 from the outside and can be used to isolate the direct contact between the first push rod 231 and the inner plate such as the stainless steel plate or the laminated board of the hot press 500 when pushing out the finished plate, thereby preventing direct rigid friction with the inner plate of the hot press 500.

[0041] Referring again to Figure 3In some embodiments of the present invention, the frame 100 is connected with a material blocking hydraulic cylinder 120 and a material blocking rod 121. The material blocking rod 121 is located on the side of the frame 100 facing the hot press 500. The material blocking hydraulic cylinder 120 is connected and drives the material blocking rod 121 to move to prevent the plate to be processed from sliding out of the frame 100, which effectively solves the problem of the plate to be processed slipping during the operation of the equipment and improves the safety and stability of the equipment. In the process of loading the plate to be processed onto the support frame 110, the material blocking rod 121 can be driven by the material blocking hydraulic cylinder 120 to timely and accurately block the plate to be processed, preventing it from sliding out of the frame 100 due to unexpected situations such as equipment vibration, operating errors, etc., avoiding injuries to operators and damage to equipment and other components. At the same time, the realization of the material blocking function also helps to ensure the continuity and stability of the production process, ensuring that the plate to be processed can be processed in accordance with the predetermined process and sequence for subsequent processing operations, thereby improving production efficiency and product quality. Optionally, there is one material blocking rod and one material blocking hydraulic cylinder, and the material blocking hydraulic cylinder is connected and drives the material blocking rod to move to the middle position of the frame to prevent the plate to be processed from sliding out (not shown in the figure). In some embodiments of the present invention, there are two material blocking rods 121, and the two material blocking rods 121 can move toward each other and close to prevent the plate to be processed from sliding out, and the two material blocking rods 121 can move back to back and open to allow the plate to be processed to slide out and enter the hot press 500. For this, two corresponding material blocking hydraulic cylinders can be set to drive (not shown in the figure), or four material blocking hydraulic cylinders 120 can be set in pairs, and the two material blocking hydraulic cylinders 120 are respectively connected to the upper and lower ends of the material blocking rod 121 and synchronously drive the material blocking rod 121 to move horizontally to prevent the plate to be processed from sliding out. In addition, it is easy to understand that in addition to being directly connected to the frame, the material blocking hydraulic cylinder and the material blocking rod can be set on the periphery of the frame (not shown in the figure), and when the two material blocking rods are closed, they reach a position that can prevent the plate to be processed from sliding out.

[0042] In some embodiments of the present invention, Figure 4 As shown, the first horizontal drive assembly 220 includes a first horizontal drive hydraulic motor, a chain transmission mechanism, a helical gear matching mechanism and a spur gear matching mechanism which are sequentially connected in transmission. Figure 1 and Figure 2 The spur gear matching mechanism includes a rack fixedly arranged on the frame 100, and a gear fixedly connected to the first push frame 230. The arrangement direction of the rack is parallel to the direction in which the finished board is pushed out of the hot press 500, so that the gear can engage with the rack to drive the first push frame 230 to push out the finished board located in the hot press 500.

[0043] In some embodiments of the present invention, Figure 3 and Figure 5As shown, the second lifting drive assembly 410 includes a second lifting drive hydraulic cylinder 411 and a guiding cross bar 412. The second pushing frame 430 is connected with traveling wheels 432, and the traveling wheels 432 are abutted against the upper surface of the guiding cross bar 412. The second lifting drive hydraulic cylinder 411 is connected to and drives the guiding cross bar 412, the traveling wheels 432 and the second pushing frame 430 to move together in the vertical direction. By adopting the way that the traveling wheels 432 are in rolling contact with the guiding cross bar 412, the second lifting drive hydraulic cylinder 411 can conveniently lift the second pushing frame 430. Moreover, the guiding cross bar 412 provides an accurate guiding effect for the horizontal movement of the second pushing frame 430, ensuring that the movement track of the second pushing frame 430 in the horizontal direction is accurate and error-free, and enabling it to accurately align with the feeding position of the hot press 500, thus improving the accuracy and stability of the pushing plate. In addition, the traveling wheels 432 are abutted against the upper surface of the guiding cross bar 412, which not only reduces the friction force of the second pushing frame 430 during the horizontal movement, making the movement smoother, but also further ensures the smoothness of the movement and reduces the influence of vibration and impact on the equipment. It can be understood that the second lifting drive hydraulic cylinder 411 can be single, two or four. For example, a single second lifting drive hydraulic cylinder directly drives the guiding cross bar to lift (not shown in the figure). For another example, two second lifting drive hydraulic cylinders are respectively connected to both ends of the guiding cross bar and operate synchronously to lift the guiding cross bar (not shown in the figure). For still another example, there are two guiding cross bars 412 symmetrically arranged on both sides of the second pushing frame 430. The four second lifting drive hydraulic cylinders 411 are grouped in pairs. The two second lifting drive hydraulic cylinders 411 in the same group are respectively connected to both ends of the same guiding cross bar 412, and the four second lifting drive hydraulic cylinders 411 in the two groups operate synchronously to lift the guiding cross bar 412.

[0044] Further, the second horizontal drive assembly 420 can refer to the structure of the first horizontal drive assembly 220 and adopt similar chain drive mechanisms, helical gear mating mechanisms and spur gear mating mechanisms. In addition, in some embodiments of the present invention, with reference to Figure 3 and Figure 5The second horizontal driving assembly 420 includes a second horizontal driving hydraulic motor 421 and a connecting vertical rod 422. The connecting vertical rod 422 is provided with a sliding rod 431 fixed to the second push frame 430 in a vertical sliding direction. The guide cross bar 412 extends along a side toward the hot press 500. The second horizontal driving hydraulic motor 421 can drive the second push frame 430 to move along the extension direction of the guide cross bar 412. It is easy to understand that the second horizontal driving hydraulic motor 421, as a power source, can provide a stable and powerful driving force for the horizontal movement of the second push frame 430, ensuring that the plate to be processed can be accurately and quickly pushed into the hot press 500. Furthermore, the connecting vertical rod 422 is provided with a sliding rod 431 sliding in the vertical direction, so that the second lifting driving hydraulic cylinder 411 can drive the sliding rod 431 to lift and lower through the cooperation of the guide cross bar 412 and the walking wheel 432, and the sliding rod 431 is fixed to the second push frame 430, so that the second push frame 430 can be lifted and lowered synchronously, and the whole lifting can also be driven by the second horizontal driving hydraulic motor 421 to move horizontally. In addition, the guide cross bar 412 extends along the side facing the hot press 500, providing a clear path for the movement of the walking wheel 432, further ensuring the accuracy and reliability of the movement of the second push frame 430.

[0045] Refer to Figure 6 , the use method according to the embodiment of the present invention is applied to the automatic plate feeding and unloading machine of the narrow layer spacing hot press according to the embodiment of the present invention, wherein the use method comprises the following steps: S100, loading the blank plate: loading the blank plate to be processed onto the support frame 110; S200, push out the finished board: the displacement assembly 300 drives the frame 100 to move to the working position, and the first push rod 231 assembly 200 pushes out the finished board located in the hot press 500; S300, manual cleaning: after the finished board is pushed out, the displacement assembly 300 drives the frame 100 to move to the cleaning station to clean the hot press 500; S400 , pushing in the embryonic plate: after manually cleaning and loading the embryonic plate, the displacement assembly 300 drives the frame 100 to move to the working station, and the second push rod assembly 400 pushes the plate to be processed into the hot press 500 .

[0046] According to the method of use of the embodiment of the present invention, by adopting the automatic plate entry and exit machine of the narrow layer spacing hot press of the embodiment of the present invention, the plate to be processed is placed on the support frame 110 in an orderly manner through the step of loading the embryo plate, so as to prepare for subsequent processing. Then, in the step of pushing out the finished plate, the first push rod 231 component 200 is used to accurately push out the finished plate in the hot press 500, thereby realizing the continuity of the production process. Then, in the manual cleaning step, after the finished plate is pushed out, the frame 100 is moved to the cleaning station through the displacement component 300, so that the workers can clean the table of the hot press 500 conveniently, thereby ensuring the cleanliness and normal operation of the equipment and helping to improve the product quality. Then, in the step of pushing in the embryo plate, after the cleaning is completed, the displacement component 300 is used again to move the frame 100 to the working station, and the second push rod component 400 is used to push the plate to be processed into the hot press 500, thereby completing the entire production cycle. In this regard, the various advantages of the equipment are fully utilized, the production efficiency is improved, the product quality is ensured, and the maintenance and management of the equipment are also convenient, and the equipment has good practicality and operability.
