Description

Technical Field

[0001] The invention relates to the technical field of pressing, and in particular to a pressing device for producing container bottom plates. Background Art

[0002] The hot pressing equipment in the pressing equipment for container bottom production is a key equipment for processing the raw materials of container bottom by hot pressing method. It is mainly composed of a heating system, a hydraulic or mechanical transmission system, a pressing plate and a control system. When working, the heating system heats up the pressing plate, and the hydraulic or mechanical transmission system applies pressure to put the raw materials such as wood and plywood and glue between the pressing plates under high temperature and high pressure, so that the glue solidifies and the water evaporates, so that each layer of material is tightly pressed together to form a container bottom that meets the quality requirements, such as the production process of facing plywood for container bottom disclosed in publication number CN100553908C.

[0003] Existing pressing equipment often removes bubbles in the base plate by vacuum exhaust, natural exhaust due to pressure difference, and exhaust due to vibration of the base plate before hot pressing. The vacuum exhaust method requires placing raw materials such as wood, plywood, and glue in a closed space of the vacuum equipment, and starting the vacuum device to rapidly reduce the air pressure in the space. Since gas always diffuses from areas with high air pressure to areas with low air pressure, bubbles originally existing in the gaps between raw materials and in the glue will continue to escape under the effect of this air pressure difference. When a certain vacuum degree is reached and maintained for a period of time, most of the bubbles are effectively removed, and then the raw materials that have been pre-treated by vacuum are placed between the pressing plates of the hot pressing equipment for subsequent hot pressing operations. However, this type of bubble removal equipment is only suitable for regular base plates; because the closed space and vacuuming method of the vacuuming equipment determine that it has poor adaptability to the shape of the material; the regular base plate can fit tightly into the sealing structure of the vacuuming equipment to ensure that no large amount of outside air will flow in during the vacuuming process, thereby maintaining a stable vacuum environment and effectively removing bubbles. However, for base plates with irregular shapes, their edges or surfaces have complex structures such as unevenness, protrusions, and depressions, which make it difficult to achieve a good seal with the sealing parts of the vacuuming equipment. Outside air can easily enter through these gaps, interfering with the vacuuming process, resulting in the inability to fully remove bubbles, and even more quality problems may be caused by residual air during the hot pressing process. Therefore, it is impossible to effectively remove bubbles from irregular base plates; The vibrator generates vibration waves to cause the bubbles in the bottom plate to rise and be discharged. However, for irregular bottom plates, the vibrator cannot remove the bubbles in the bottom plate because the irregular bottom plate has a complex structure, and the material distribution and thickness of each part are different. When the vibration wave propagates in it, it will be unevenly distributed due to reflection, refraction and scattering. For example, in the concave part, the energy of the vibration wave is weakened, and the bubbles are difficult to be discharged; the protruding parts are easily damaged due to the concentration of the vibration wave. At the same time, it is difficult for the irregular bottom plate to maintain a good relative position and contact state with the vibrator when placed, which greatly reduces the vibration exhaust effect, and it is difficult to effectively remove bubbles and meet the production quality requirements.

[0014] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. Through the concave frame, electric lifting plate, limit assembly and spoiler assembly in the hot and cold mechanism, the bottom plate before the pressing mechanism can be preheated and the bubble removal operation can be realized. When the bottom plate enters the concave frame through the bottom plate slider, the electric lifting plate will descend, and then the concave frame will be sealed, so that the bottom plate is sealed in the concave frame, and the limit assembly is in contact with the upper end surface of the bottom plate. At the same time, the particles in the heat conduction box begin to be transported to the limit assembly, and the limit assembly can spray the heated particles in the heat conduction box onto the surface of the bottom plate, thereby achieving the heated particles. The purpose of preheating the bottom plate is to preheat the particles. When the particles are transported to the limiting component, the hot air blower is also started. The hot air blower begins to transport air into the concave frame. The air transported by the hot air blower will change into irregular turbulence through the transformation of the spoiler component. The turbulence will then act on the particles, causing the particles to flip over, and the flipped particles will collide with the bottom plate, thereby achieving the purpose of eliminating bubbles in the glue of the bottom plate to avoid the generation of voids, improving the quality and performance of the bottom plate, reducing product defects caused by glue problems, and improving production efficiency and finished product qualification rate.

[0015] 2. The pressing box, heat pipe assembly, shock-collecting assembly and base heating assembly in the pressing mechanism can realize the pressing of the base plate, wherein a liquid heater is used to transport heated liquid into the heat pipe assembly to heat the pressing block by the heat pipe assembly, and the pressing of the base plate is realized by the heated pressing block, while the protective cover can lock the heat released by the heat pipe assembly in the pressing block, and when the liquid flows in the heat pipe assembly, the heat pipe assembly can also vibrate slightly, and the vibration waves of the heat pipe assembly through the shock-collecting assembly are collected and transmitted to the pressing block, so that the pressing block also squeezes slight vibration, and the micro-vibration can promote the uniform distribution and full penetration of the glue layer, and enhance the bonding force between the layers of materials, and the base heating assembly can heat the other side of the base plate, thereby realizing the heating of both sides of the base plate during pressing, ensuring the overall uniform heating, and avoiding deformation and uneven curing caused by single-sided heating.

[0016] 3. Through the liquid heater, heat transfer box and particle cooling assembly in the circulation mechanism, it is possible to transport heated or cooled particles to the limit assembly, and it is also possible to transport heated liquid to the heat pipe assembly and the base heating assembly. The heat transfer box can use the heat generated by the liquid heater to heat the particles, and transfer the heated liquid to the limit assembly that needs to be pretreated to achieve the purpose of preheating the bottom plate. The preheated particles will then enter the particle cooling assembly, and the particle cooling assembly can cool the particles. The cooled particles will be transported back to the limit assembly after the bottom plate is pressed together to cool the bottom plate, and return to the heat transfer box after cooling. The particles are heated by the residual heat of the liquid heater to preheat the bottom plate, so that the glue can be more evenly distributed and solidified during subsequent pressing, thereby improving the bonding strength between the layers of the bottom plate and ensuring its structural stability. After the bottom plate is pressed together, the cooled particles can cool it down again, effectively avoiding deformation, internal stress concentration and other problems caused by sudden temperature changes, and ensuring the dimensional accuracy and stable performance of the bottom plate.

[0036] Reference Figure 12 to Figure 13 A boost pump 46 and a suction pump 47 are fixedly connected to the inner bottom of the base 1 near the particle cooling assembly 45, and the output end of the heat conduction box 42 is fixedly connected to a connecting pipe 421, the other end of the connecting pipe 421 is connected to the input of the suction pump 47, the output end of the suction pump 47 is connected to the second particle conveying pipe 26, and the output end of the boost pump 46 is connected to the other end of the first particle conveying pipe 25.

[0037] The suction pump 47 uses the connecting pipe 421 to transport the particles in the heat transfer box 42 to the inner arc box 231, and can also absorb the particles sprayed on the bottom plate. The booster pump 46 uses the first particle delivery pipe 25 and has the same purpose as the suction pump 47. The booster pump 46 is responsible for absorbing the preheated particles into the particle cooling assembly 45, and after the bottom plate is pressed, the cold particles in the particle cooling assembly 45 are transferred to the inner arc box 231 to cool the bottom plate, and after the bottom plate is cooled, the suction pump 47 absorbs the particles into the heat transfer box 42.

[0038] Reference Figure 1 to Figure 2 , Figure 12 to Figure 13 The particle cooling assembly 45 includes an outer box 451 fixedly connected to the inner bottom of the base 1, an inner box 452 is sleeved inside the outer box 451, and there is a gap between the inner box 452 and the outer box 451, particles are stored in the inner box 452, and the four opposite surfaces of the inner box 452 and the outer box 451 are fixedly connected with a plurality of heat conducting plates 455 in a linear array from top to bottom, at least one exhaust fan 453 is installed on one side of the outer box 451, and a plurality of air inlet holes 454 are opened in a rectangular array on the other side of the outer box 451, a plurality of liquid capsules 456 are fixedly connected to the inner wall of the inner box 452 in a rectangular array, and coolant is stored in the liquid capsules 456, a suction and exhaust device 457 is clamped on the inner bottom of the inner box 452, and a connecting valve 48 is fixedly connected to the upper end face of the outer box 451, the input end of the connecting valve 48 is connected with the suction and exhaust device 457 through a pipeline, and the output end of the connecting valve 48 is connected with the input end of the boost pump 46 through a pipeline.

[0039] The connecting valve 48 can be used to connect the boost pump 46 to the inner box 452 in the particle cooling assembly 45, and the liquid capsule 456 can cool the particles entering therein by using the coolant stored therein. The coolant stored in the liquid capsule 456 can release the absorbed heat into the gap between the inner box 452 and the outer box 451 by using the heat conductive sheet 455, and release the heat released into the gap into the air through the air inlet 454 and the exhaust fan 453, so as to complete the cooling of the coolant.

[0040] The operating principle of this embodiment is as follows: Step 1: First, the bottom plate to be pressed by the staff is placed on the bottom plate slider 11. The bottom plate slider 11 can be driven by manual or mechanical means, and the bottom plate of this scheme refers to the container bottom plate, so that the bottom plate slider 11 slides on the upper end surface of the base 1, so as to transport the bottom plate into the concave frame 21. When the bottom plate slider 11 drives the bottom plate into the concave frame 21, the staff sends a descending command to the sliding driver of the electric lifting plate 22 through the controller, and the sliding driver drives the slide plate to descend until the electric lifting plate 22 completely closes the two side openings of the concave frame 21. The other side was not sealed before, forming a relatively sealed space; When the electric lifting plate 22 descends in the concave frame 21, the liquid heater 41 starts to work, thereby heating the liquid stored therein. The liquid stored in the liquid heater 41 needs to have good thermal conductivity, stability and boiling point, such as: thermal oil, silicone oil, water-ethylene glycol solution, etc., and the heating temperature of the liquid by the liquid heater 41 can be controlled by the staff in the controller according to the material properties of the bottom plate, the type of glue and the process requirements. For example, the bottom plate of the container is made of poplar multi-layer plywood. The poplar material is relatively soft and has general heat resistance. It is prone to deformation, carbonization and other problems when heated for a long time at high temperature. The heating temperature is usually 120-160°C, and phenolic resin glue is used. Phenolic resin glue has good bonding strength and heat resistance, but it needs to be fully cured within a specific temperature range. The suitable curing temperature is usually between 150-180°C, so the staff needs to combine the material and glue characteristics to set the heating temperature of the liquid heater 41 to about 150°C on the controller. The specific temperature is adjusted by the staff in the controller according to the actual situation.

[0041] During the process of liquid heating by the liquid heater 41, the heat it dissipates is transferred to the particles in the heat-conducting box 42 through the heat-conducting contact surface with the heat-conducting box 42 to heat it up. The particles need to have the characteristics of good softness, fine particles and relatively low heat resistance, such as vermiculite particles, perlite particles and silica gel particles, and a temperature detector is provided in the heat-conducting box 42. The temperature detector is a prior art and is not drawn in the figure. When the temperature detector detects that the particles have been heated to about 80°C, the temperature detector will feedback information to the controller, and the controller will start the suction pump 47 to pump the hot particles in the heat-conducting box 42 through the connecting pipe 421. The particles are conveyed to the diverter valve 235 of the limit assembly 23 through the second particle conveying pipe 26 and the telescopic pipe 236, and the diverter valve 235 evenly distributes the hot particles to the four transmission pipes 232, and then enter the inner arc box 231 through the transmission pipe 232, and finally sprayed onto the surface of the base plate from the spray hole 2311. Since the inner arc box 231 and the electric lifting plate 22 are slidably connected, when the electric lifting plate 22 descends, the inner arc box 231 and the base plate are in contact. During the spraying process, the hot particles are in full contact with the base plate, and the heat is transferred to the base plate to preheat the base plate, so that the glue is initially activated and the subsequent bonding effect is enhanced.

[0042] Among them, when the suction pump 47 is started, the hot air blower 213 is also started. At this time, the suction pump 47 rotates forward, thereby sucking the outside air into the concave frame 21. The hot air blower 213 of this scheme has an air filtering function to remove impurities such as air dust, and then enters the inside of the concave frame 21. When the input air passes through the second screen 234 and enters the air vent 233, the hot air blower 213 has a heating function, so the air transported to the air vent 233 has a temperature, thereby further improving the preheating effect of the hot particles on the bottom plate. The air flow will impact the inclined plate 242 of the spoiler component 24. After the inclined plate 242 is impacted by the air, The fixed rod 241 is driven to rotate, and the baffle 244 and the spoiler 245 are also rotated together. The rotation of the baffle 244 and the spoiler 245 changes the flow direction of the air, making it irregular turbulence. The turbulence acts on the hot particles being sprayed on the bottom plate, causing the hot particles to flip. The flipped hot particles continuously collide with the surface of the bottom plate. This collision can break the bubbles in the glue because the glue has been initially activated and has a liquefied phenomenon at this time, thereby avoiding the generation of cavities due to the presence of bubbles in the subsequent pressing process, thereby improving the quality of the bottom plate. The air transported to the air permeable cover 233 will be discharged through the first screen 212; It should be noted that: this scheme uses particles to preheat regular base plates and irregular base plates and remove most of the bubbles in the base plates, thereby enhancing the subsequent pressing operation of the pressing mechanism 3. On the one hand, the preliminary treatment greatly reduces the number of bubbles in the base plate glue, reduces the burden of the subsequent pressing mechanism 3 during vibration and exhaust, and makes it easier for residual bubbles to be vibrated out, reducing the risk of bubble residue, avoiding defects such as voids and stratification, and improving the quality of the base plate; on the other hand, the preliminary preheating reduces the viscosity of the glue and enhances its fluidity. When the pressing mechanism 3 vibrates, the glue can better fill the gaps between the materials, be evenly distributed and fully penetrate into each layer of the material, enhance the bonding effect between the layers of the material, and improve the overall structural stability of the base plate. At the same time, it reduces the wear of the equipment caused by handling a large number of bubbles, extends the service life of the equipment, reduces maintenance costs, and improves production efficiency.

[0043] Among them, after the hot particles complete preheating of the bottom plate (to determine whether the bottom plate is preheated, the staff sets the contact time between the bottom plate and the hot particles in the controller according to the same material bottom plate, different glues and specific processes, combined with production experience), the controller will control the start of the boost pump 46 to rotate forward, so that the boost pump 46 is connected with the limit component 23 and the inner box 452 of the particle cooling component 45 through the first particle conveying pipe 25 and the connecting valve 48. Under the action of the suction force of the boost pump 46, the preheated hot particles are sucked into the inner box 452 of the hot particle cooling component 45 from the inner arc box 231 of the limit component 23 through the diverter valve 235 and the telescopic tube 236, and then through the first particle conveying pipe 25, so as to achieve cooling of the hot particles; It should be noted that: before the bottom plate enters the concave frame 21, the lifting plate of the electric lifting plate 22 is in an ascending state, so that the openings on both sides of the concave frame 21 are open, so that the bottom plate can enter through the bottom plate slider 11. When the bottom plate enters the concave frame 21 and is in place, the controller sends an electrical signal to the sliding driver of the electric lifting plate 22, and the sliding driver converts electrical energy into mechanical energy to drive the slide plate to descend until the electric lifting plate 22 completely closes the openings on both sides of the concave frame 21 to achieve sealing of the concave frame 21, creating a relatively closed environment for preheating the bottom plate of the particles and removing bubbles. When the particles are preheated and the bottom plate is ready to enter the pressing mechanism 3, the controller sends an instruction again, and the sliding driver drives the slide plate to rise, opens the openings on both sides of the concave frame 21, so that the bottom plate can slide out smoothly and enter the subsequent pressing process, and the hot air blower 213 is also turned off.

[0044] Step 2: After the pretreatment is completed, the bottom plate slider 11 will drive the bottom plate into the pressing box 31. When the bottom plate enters the pressing box 31, the staff controls the telescopic end of the electric drive hydraulic device 32 to extend through the controller, pushing the protective cover 33 and the pressing block 34 connected thereto to move downward, and the pressing block 34 gradually approaches and contacts the bottom plate, exerting pressure on the bottom plate; The bottom plate slider 11 drives the bottom plate to enter the pressing box 31, and the liquid delivery pump 43 starts in advance, so as to extract the hot liquid heated by the liquid heater 41 and deliver it to the first diverter valve 44. The first diverter valve 44 delivers the hot liquid to the water inlet pipe 3511 of the heat pipe assembly 35 and the input pipe 374 of the base heating assembly 37 respectively. The hot liquid delivered by the water inlet pipe 3511 flows in the S-shaped curved pipe 351. Since the S-shaped curved pipe 351 has a confluence ball 352, the S-shaped curved pipe 351 will vibrate slightly when the liquid flows. The reason why the flow confluence ball 352 in the S-shaped curved tube 351 causes slight vibration when the liquid flows is: Since the confluence ball 352 in the S-shaped curved tube 351 changes the flow state of the liquid in the pipeline, when the liquid flows through the confluence ball 352, its cross-sectional area changes. According to the principles of fluid mechanics, the flow velocity will change accordingly. The change in flow velocity will cause pressure fluctuations. At the same time, the flow direction of the liquid also changes when flowing through the confluence ball 352, which impacts the pipe wall. The combined effect of these changes in flow velocity, pressure and flow direction causes the S-shaped curved tube 351 to be subjected to an unstable force, thereby generating slight vibrations when the liquid flows.

[0045] Among them, since the shock-guiding rod 361 and the shock-guiding block 362 of the shock-focusing assembly 36 are located in the gap of the S-shaped curved tube 351, they can collect the vibration waves generated by the S-shaped curved tube 351 and transmit the vibration waves to the pressing block 34, so that the pressing block 34 also generates slight vibrations. This micro-vibration helps the glue to be evenly distributed and fully penetrated between the various layers of the base plate materials, thereby enhancing the bonding force. At the same time, this vibration can also further remove a small amount of bubbles in the base plate. The elastic tube 372 of the base heating assembly 37 is filled with hot liquid to heat the bottom of the base plate, and together with the heat pipe assembly 35, double-sided heating of the base plate is achieved to ensure that the overall base plate is heated evenly, avoiding deformation, uneven curing and other problems caused by single-sided heating.

[0046] Step 3: After the bottom plate is pressed in the pressing mechanism 3, the bottom plate slider 11 transports the bottom plate to the concave frame 21 again, and the electric lifting plate 22 also drops again. At this time, the controller starts the reverse rotation of the boost pump 46 (it should be noted that the forward rotation of the boost pump 46 sucks the particles in the limit component 23 into the particle cooling component 45, and the reverse rotation of the boost pump 46 sucks the particles in the particle cooling component 45 into the limit component 23, and the forward rotation of the suction pump 47 sucks the particles from the heat conduction box 42 into the limit component 23, and the reverse rotation of the suction pump 47 sucks the particles from the limit component 23 into the heat conduction box 42). The cold particles in the particle cooling component 45 begin to be sucked into the boost pump 46. The particle cooling component 45 includes an outer box 451 and an inner box 452. The inner box 452 stores the cooled particles. Under the suction of the boost pump 46, the cold particles are sucked out of the inner box 452 enters the booster pump 46 through the pipeline. After the booster pump 46 sucks in the cold particles, it transports the cold particles to the limit assembly 23 through the first particle conveying pipe 25. At the same time, when the booster pump 46 transmits the cold particles to the limit assembly 23, the controller controls the two-position three-way valve 214 to switch the connection state with the first particle conveying pipe 25, and sprays the cold particles onto the surface of the bottom plate through the spray hole 2311 through the telescopic tube 236, the diverter valve 235 and the transmission pipe 232. When the cold particles come into contact with the high-temperature bottom plate, they quickly absorb the heat of the bottom plate to reduce the temperature of the bottom plate. At the same time, the temperature of the cold particles themselves increases to achieve the purpose of cooling the bottom plate. In this process, the cold particles continue to absorb heat from the bottom plate to avoid adverse effects of sudden temperature changes on the bottom plate, thereby ensuring the dimensional accuracy and stable performance of the bottom plate. In the process of cold particles cooling the bottom plate, the hot air blower 213 will not start.

[0047] Among them, when the cold particles complete cooling the bottom plate, the controller sends a start command to the suction pump 47 (at this time the suction pump 47 reverses), the suction pump 47 starts to work, and generates suction in the second particle conveying pipe 26. Since the diverter valve 235, the transmission pipe 232 and the spray hole 2311 of the limit assembly 23 are connected, the suction generated by the suction pump 47 is transmitted to the inner arc box 231 of the limit assembly 23 through the second particle conveying pipe 26. At this time, the heated particles enter the transmission pipe 232 from the spray hole 2311 of the inner arc box 231 under the action of suction, and then converge to the telescopic pipe 236 through the diverter valve 235, and finally are sucked into the suction pump 47 through the second particle conveying pipe 26. While the suction pump 47 absorbs the particles, the controller controls the two-position three-way valve 214 to switch and connect with the second particle conveying pipe 26, and the particles absorbed by the suction pump 47 will enter the heat conduction box 42 for reheating to prepare for the next preheating.

[0048] Among them, the process of cooling the particles in the particle cooling assembly 45 is supplemented; When the preheated particles enter the inner box 452 of the particle cooling assembly 45, the heat carried by the particles begins to exchange with the surrounding environment. The inner walls and the inner bottom of the inner box 452 are fixedly connected with a plurality of liquid capsules 456 in a rectangular array. The liquid capsules 456 store cooling liquid. Since the particle temperature is higher than the cooling liquid temperature, according to the heat transfer principle, the heat is transferred from the high-temperature particles to the low-temperature cooling liquid, causing the particle temperature to begin to decrease. After the cooling liquid stored in the liquid capsules 456 absorbs the heat of the particles, the temperature rises. At this time, the heat conduction of the inner box 452 and the outer box 451 on the opposite sides is The sheet 455 works by transferring the heat absorbed by the liquid capsule 456 to the gap between the inner box 452 and the outer box 451. At the same time, the exhaust fan 453 installed on one side of the outer box 451 is started, and the external cold air is sucked into the gap between the inner box 452 and the outer box 451 from the air inlet 454 on the other side. The cold air flows in the gap, continuously taking away the heat transferred by the heat conductive sheet 455, and then is discharged to the external environment through the exhaust fan 453. Such continuous air circulation can take away the heat dissipated by the coolant in time, maintain the low temperature state of the coolant, and thus continuously cool the particles.
