Description

Technical Field

[0001] This utility model relates to the field of cooling technology for coated wood veneer production, specifically a cooling device for coated wood veneer production. Background Technology

[0002] Wood veneer, also known as thin wood, is a thin sheet of wood with the characteristics of precious tree species. Its thickness is usually between 0.1mm and 1mm. It is mainly obtained from wood by slicing or rotary cutting. In the production process of coated wood veneer, the cooling process is crucial.

[0003] Existing cooling devices for coated wood veneer production typically place the wood veneer inside a space that drives the cooling system. The cooling system cools the wood veneer to ensure its performance.

[0004] However, existing cooling devices for coated wood veneer production place the veneer directly into a space with a cooling system. If the temperature emitted by the cooling system is too low, the cooling rate is too fast, resulting in uneven shrinkage of the veneer surface and interior, causing surface stress and cracking. If the pre-cooling temperature is too high, the cooling time for the veneer is prolonged. Utility Model Content

This device solves the problem that if the temperature emitted by the cooling system is too low when the wood veneer is placed directly into a space with a cooling system, the cooling rate will be too fast, resulting in uneven shrinkage of the surface and interior of the wood veneer, which will cause stress on the surface and thus cracking.

The top is fitted with a water inlet pipe fixed to the front of the cabinet and connected to the front of the storage tank. The cooler is fixed to the front of the cabinet, with one end extending into the interior of the cabinet away from the electric slider, and the other end penetrating the front of the cabinet and extending into the interior of the storage tank. Three isolation devices are provided, all located inside the cabinet. The circulating pump draws water from inside the storage tank into the water drains inside the two cooling tanks through a distribution pipe. The water inlet pipe and the cooler provide water to the storage tank and cool the cooling tanks, respectively. The isolation devices divide the cabinet into multiple cooling spaces.

[0008] Preferably, the isolation device includes a housing, which is fixedly connected to the bottom of the inner wall of the box; a partition is inserted into the inner wall of the housing, and its top is respectively attached to the bottom of the electric slide rail and the top of the inner wall of the box; a telescopic rod is fixedly connected to the bottom of the inner wall of the box, and its output end is fixedly connected to the top of the outer wall of the partition; wherein, the partition is moved inside the housing by the telescopic rod to achieve the separation of the internal space of the box.

[0011] Beneficial effects

[0012] This invention provides a cooling device for the production of coated wood veneer. It offers the following advantages: The cooling device, through the cooperation of a cooling box, a storage box, and a refrigerator, cools two separate cooling spaces within the box, divided by an isolation device. The rightmost cooling space, directly affected by the refrigerator, has the lowest internal temperature. The space closest to the electric slider has the highest temperature because the refrigerator's output first cools the liquid inside the storage box before a circulating pump draws it into the water drain. The middle cooling space is cooled by controlling the isolation device, allowing air to slowly circulate from the coldest space to the middle space. This results in a uniform cooling effect with different temperatures in the three spaces separated by the isolation device. After a period of time, the isolation device is activated, and the electric slider moves the wood veneer into the second coldest space, and finally into the coldest space, until the cooling process is complete. This step-by-step cooling process gradually lowers the temperature of the wood veneer, allowing for uniform contraction of the surface and interior, reducing stress.

[0013] Through the cooperation of the casing, partitions, and telescopic rods, when the veneer enters the space with the highest temperature, all three partitions are closed. After the veneer has passed through the first space for a period of time, the leftmost telescopic rod is activated. The output end of the telescopic rod drives the partition to move towards the inner wall of the casing, allowing the veneer to pass through the second space. Then, the telescopic rod drives the partition to reset, ensuring that the air inside each space does not circulate excessively. After cooling for a period of time in the second space, the middle telescopic rod performs the same movement. Finally, the veneer undergoes gradual cooling, allowing the surface and interior of the veneer to shrink evenly, reducing stress generation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Existing cooling devices for coated wood veneer production place the veneer directly into a space equipped with a cooling system. If the temperature emitted by the cooling system is too low, the cooling rate is too fast, resulting in uneven shrinkage of the veneer surface and interior, causing surface stress and cracking. If the pre-cooling temperature is too high, the cooling time for the veneer is prolonged.

[0022] In view of this, the present invention provides a cooling device for the production of coated wood veneer. Through the cooperation of a cooling box, a storage box, and a refrigerator, the two output ends of the refrigerator cool the cooling spaces on both sides of the box, which are separated by an isolation device. Since the rightmost cooling space is directly affected by the refrigerator, its internal temperature is the lowest. The space closest to the electric slider has the highest internal temperature because the output end of the refrigerator first cools the liquid inside the storage box and then pumps the liquid into the water drain via a circulation pump. The middle cooling space is cooled by controlling the isolation device, allowing air from the coldest space to slowly circulate to the middle cooling space. Ultimately, the three spaces separated by the isolation device inside the box have different internal temperatures, achieving a uniform cooling effect. After a period of time, the isolation device is activated, and the electric slider moves the wood veneer into the second lowest temperature space, and finally into the lowest temperature space, until the cooling of the wood veneer is completed. Through the step-by-step cooling process, the wood veneer gradually cools down, allowing the surface and interior of the wood veneer to shrink evenly, reducing stress generation.

[0023] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0024] Example 1: By Figure 1-5 It is known that a cooling device for producing coated wood veneer includes a housing 1. An electric slide rail 11 is fixedly connected to the top of the inner wall of the housing 1, and an electric slider 12 is slidably engaged with the outer wall of the electric slide rail 11. The cooling device for producing coated wood veneer also includes a cooling unit 2, a sensing device 3, and a fixing device 4. The cooling unit 2 is disposed inside the housing 1; the sensing device 3 is disposed on the housing 1; and the fixing device 4 is disposed below the electric slider 12. The cooling unit 2 uniformly cools the wood veneer, the sensing device 3 senses the movement of the electric slider 12 and the temperature of each space in the housing 1, and the fixing device 4 fixes the wood veneer.

[0025] In the specific implementation process, it is worth noting that by setting the cooling unit 2 at the front and back inside the box 1, uniform cooling of the wood veneer is achieved. The cooling unit 2 is controlled by the sensing device 3, and the fixing device 4 completes the fixing of the wood veneer. The electric slide rail 11 is model HGH20CA, and the electric slider 12 is model MS20.

[0026] Furthermore, the cooling unit 2 includes a cooling tank 21, a storage tank 22, a circulating pump 23, a distribution pipe 24, a water drain 25, a water inlet pipe 26, a cooler 27, and an isolation device 28. Two cooling tanks 21 are provided, respectively located on the front and rear sides of the inner wall of the housing 1 near the electric slider 12, and fixedly connected to the bottom of the inner wall of the housing 1. The storage tank 22 is located between the two cooling tanks 21 and fixedly connected to the bottom of the inner wall of the housing 1. The circulating pump 23 is fixedly connected to the bottom of the inner wall of the storage tank 22, and its output end penetrates through the outer wall of the storage tank 22. One end of the distribution pipe 24 near the circulating pump 23 is connected to the output end of the circulating pump 23, and the other two ends extend into the interior of the two cooling tanks 21. The water drain 25 is located inside the cooling tank 21. Both ends are connected to the end of the diversion pipe 24 and the top of the storage tank 22 respectively; the water inlet pipe 26 is fixed to the front of the tank 1 and connected to the front of the storage tank 22; the cooler 27 is fixed to the front of the tank 1, with one end extending into the side of the tank 1 away from the electric slider 12, and the other end penetrating the front of the tank 1 and extending into the interior of the storage tank 22; three isolation devices 28 are provided, all of which are located inside the tank 1; wherein, the circulation pump 23 draws water from the inside of the storage tank 22 into the water drains 25 inside the two cooling tanks 21 through the diversion pipe 24, and provides water to the storage tank 22 and cools the cooling tank 21 through the water inlet pipe 26 and the cooler 27 respectively, and the isolation devices 28 divide the tank 1 into multiple cooling spaces;

[0027] In the specific implementation process, it is worth noting that when the veneer needs to be cooled, the circulation pump 23 is started first. The circulation pump 23 draws the water inside the storage tank 22 through the diversion pipe 24 to the water drains 25 inside the two cooling tanks 21. Then, the cooler 27 is started. The two outputs of the cooler 27 cool the cooling spaces on both sides of the box 1, which are separated by the isolation device 28. Since the cooling space on the far right is directly affected by the cooler 27, its internal temperature is the lowest. The space closest to the electric slider 12 needs to have the liquid inside the storage tank 22 cooled first by the output of the cooler 27, and then the liquid is drawn to the water drain by the circulation pump 23. Inside the enclosure 25, the cooling space closest to the electric slider 12 has the highest temperature. The middle cooling space is controlled by the isolation device 28 on the far right, which allows air to slowly circulate from the coldest space to the middle cooling space. Ultimately, the three spaces inside the enclosure 1 separated by the isolation device 28 have different temperatures. The space where the wood veneer first enters has the highest temperature. The electric slider 12 moves the wood veneer along the electric slide rail 11 into the enclosure 1. Both the front and back of the wood veneer are cooled by the water outlet 25, achieving uniform cooling. After a period of time, the isolation device 28 is activated, and the electric slider 12 moves the wood veneer into the space with the second highest temperature. The cooling process begins with a step-by-step cooling process, moving from the lowest temperature area to the lowest temperature area until the wood veneer is cooled completely. This gradual cooling process allows the wood veneer to cool down gradually, enabling even shrinkage of the surface and interior, reducing stress. Both the front and back of the housing 1 have access doors connected by pivot pins. A fan is installed on the side of the cooling box 21 near the access door. Both the front and back of the cooling box 21 have through-holes. The fan blows cool air from the water drain 25 into the interior of the housing 1. Water is replenished to the storage tank 22 via the water inlet pipe 26. The circulating pump 23 is a CRN2-4, and the refrigerator 27 is a Z model. The B45KQE-TFD-552 refrigerator 27 mainly consists of four components: compressor, condenser, expansion valve, and evaporator. Its working principle is roughly as follows: In the refrigeration system, the refrigerant is in a low-pressure state in the evaporator. After the low-temperature, low-pressure liquid refrigerant flowing out of the expansion valve enters the evaporator, the boiling point of the refrigerant also decreases due to the pressure reduction, and the refrigerant begins to boil and vaporize. During the vaporization process, the refrigerant needs to absorb a large amount of heat to overcome the attraction between liquid molecules, thus changing from a liquid state to a gas state. At this time, the refrigerant in the evaporator exchanges heat with the liquid that needs to be cooled. The refrigerant absorbs heat from the liquid, thereby lowering the liquid temperature and achieving the purpose of refrigeration.

[0028] Furthermore, the isolation device 28 includes a housing 281, a partition 282, and a telescopic rod 283. The housing 281 is fixedly connected to the bottom of the inner wall of the box 1; the partition 282 is inserted into the inner wall of the housing 281, and its top is respectively attached to the bottom of the electric slide rail 11 and the top of the inner wall of the box 1; the telescopic rod 283 is fixedly connected to the bottom of the inner wall of the box 1, and its output end is fixedly connected to the top of the outer wall of the partition 282; wherein, the partition 282 is moved inside the housing 281 by the telescopic rod 283, thereby separating the internal space of the box 1.

[0029] In the specific implementation process, it is worth noting that when the veneer enters the space with the highest temperature, all three partitions 282 are in the closed state. After the veneer has passed through the first space for a period of time, the leftmost telescopic rod 283 is activated. The output end of the telescopic rod 283 drives the partition 282 to move towards the inner wall of the casing 281, allowing the veneer to pass through the second space. Afterward, the telescopic rod 283 drives the partition 282 to return to its original position, ensuring that the air inside each space does not circulate excessively. After cooling for a period of time from the second space, the middle telescopic rod 283 performs the same movement. Finally, the veneer undergoes staged cooling, allowing the surface and interior of the veneer to shrink evenly, reducing stress generation. The materials of 282 and shell 281 can be set as phenolic resin board, which has excellent heat insulation performance. When dividing the space of the box 1, it can effectively prevent heat transfer between different areas, so that the temperature of each space remains relatively independent and stable. The cooling space in the middle is activated by the rightmost telescopic rod 283. The telescopic rod 283 drives the partition 282 to move slightly, so that the cold air inside the coldest space can slowly flow into the middle cooling space. The temperature inside the three cooling spaces can be monitored by the sensing device 3. When the temperature of the middle cooling space is in the middle of the three cooling spaces, the rightmost telescopic rod 283 drives the partition 282 to reset.

[0030] Specifically, when using this cooling device for coated wood veneer production, when cooling of the wood veneer is required, the circulation pump 23 is first started. The circulation pump 23 draws water from the storage tank 22 through the diversion pipe 24 into the water drains 25 inside the two cooling tanks 21. Then, the cooler 27 is started. The two outputs of the cooler 27 cool the cooling spaces on both sides of the box 1, which are separated by the isolation device 28. Because the rightmost cooling space is directly affected by the cooler 27, its internal temperature is the lowest. The space closest to the electric slider 12 has the highest internal temperature because the output of the cooler 27 first cools the liquid inside the storage tank 22, and then the liquid is drawn into the water drain 25 by the circulation pump 23. The middle cooling space is cooled by controlling the rightmost isolation device 28, allowing air to slowly circulate from the coldest space to the middle cooling space. Ultimately, the three spaces separated by the isolation device 28 inside the box 1 have different internal temperatures, with the space where the wood veneer first enters having the highest temperature. The electric slider 12 drives the wood veneer to move along the electric slide rail 11 and enter the interior of the housing 1. Both the front and back of the wood veneer are cooled by the water drain 25, achieving a uniform cooling effect. After a period of time, when the wood veneer enters the space with the highest temperature, the leftmost partition 282 is closed, and the middle partition 282 moves downward under the action of the telescopic rod 283 to ensure air circulation between the second and third spaces. After the wood veneer has passed through the first space for a period of time, the leftmost telescopic rod 283 is activated. The output end of the telescopic rod 283 drives the partition 282 to move towards the inner wall of the housing 281, allowing the wood veneer to pass through the second space. Then, the telescopic rod 283 drives the partition 282 to reset, ensuring that the air circulation in each space is not excessive. After cooling for a period of time in the second space, the middle telescopic rod 283 moves in the same way. Finally, the wood veneer undergoes a step-by-step cooling process until the cooling work is completed. Through the step-by-step cooling process, the wood veneer gradually cools down, allowing the surface and interior of the wood veneer to shrink evenly and reducing stress generation.

[0031] Example 2: From Figure 1-5 It is known that the sensing device 3 includes a thermometer 31, a photoelectric sensor 32, and a controller 33. Three thermometers 31 are provided, all fixedly connected to the top of the inner wall of the box 1, and respectively located on the side of the three partitions 282 near the cooling box 21. Three photoelectric sensors 32 are provided, respectively fixedly connected to the side of the outer wall of the three partitions 282 near the electric slider 12. The controller 33 is fixedly connected to the front of the box 1. The thermometers 31 monitor the temperature of each space in the box 1, the controller 33 controls the working intensity of the cooler 27, and the photoelectric sensors 32 sense the movement of the electric slider 12.

[0032] In the specific implementation process, it is worth noting that thermometer 31 monitors the temperature of each space in the cabinet 1, and controller 33 controls the working intensity of the cooler 27, the lifting and lowering of the partition 282 between the second and third spaces, and the working intensity of the circulation pump 23. Photoelectric sensor 32 senses the movement of the electric slider 12 to ensure the timely start and reset of the telescopic rod 283. The photoelectric sensor 32 is model E3Z-LS63, and the controller 33 is model S7-1200. Regarding the connection between controller 33 and cooler 27, the controller 33 and cooler 27 are first connected... A stable power supply meeting the rated voltage requirements is supplied. Simultaneously, the power supply line of the cooler 27 is correctly connected according to its electrical specifications. The temperature signal collected by the thermometer 31 is connected to the controller 33 via an analog input module, enabling the controller 33 to acquire real-time temperature data within the cooling box 21. The controller 33 is connected to the control circuit of the cooler 27 via a digital output module. When the temperature exceeds the set upper limit, the controller 33 outputs a high-level signal, triggering the start-up circuit of the cooler 27 and causing it to begin operation. When the temperature drops to the set lower limit, the controller 33 outputs a low-level signal, stopping the cooler 27 from operating.

[0033] Furthermore, the fixing device 4 includes a first fixing plate 41, a second fixing plate 42, and a fixing bolt 43. The first fixing plate 41 is fixedly connected to the bottom of the electric slider 12; the second fixing plate 42 is disposed on the outer side of the first fixing plate 41; and the fixing bolt 43 is inserted between the first fixing plate 41 and the second fixing plate 42. The wood veneer is fixed by the first fixing plate 41, the second fixing plate 42, and the fixing bolt 43.

[0034] In the specific implementation process, it is worth noting that the combination of the first fixing plate 41, the second fixing plate 42, and the fixing bolts 43 can adapt to the fixing requirements of veneers of different sizes, improving the versatility of the device and the flexibility of production. Different fixing methods can be adopted according to the actual situation. For example, hooks can be used, with a hanger installed on the top of the veneer and connected to the hanger on the top of the veneer via hooks. Alternatively, tape can be used; a straight plate can be pre-installed at the bottom of the electric slider 12, and the top of the veneer can be fixed to the outer wall of the straight plate with tape. However, care should be taken to apply the tape smoothly to the veneer, avoiding air bubbles or wrinkles to ensure a good fixing effect. After cooling, the tape should be carefully peeled off to prevent adhesive residue from remaining on the veneer.

[0035] Specifically, based on the above embodiment 1, the thermometer 31 monitors the temperature of each space in the box 1, the controller 33 controls the working intensity of the cooler 27, and the photoelectric sensor 32 senses the movement of the electric slider 12 to ensure the timely start and reset of the telescopic rod 283. Through the combination of the first fixing plate 41, the second fixing plate 42 and the fixing bolt 43, it can adapt to the fixing requirements of different sizes of wood veneer, improving the versatility of the device and the flexibility of production.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
