Description
Technical Field
[0001] This utility model relates to the field of hot press technology for veneer, and in particular to a hot press for veneer of irregular curved surfaces. Background Technology
[0002] In the field of hot press technology for veneer, the operational stability of hot presses for irregular curved surfaces is closely related to product quality. Currently, the main structure of a hot press typically includes key components such as heating elements, hot press plates, and transmission devices. These components work together to achieve hot pressing processing of irregular curved materials.
[0003] However, in actual long-term use, existing hot press machines for laminating irregular curved surfaces have revealed many problems. On the one hand, when the hot press body is running continuously, the heating element will continuously generate heat, and dust is very easy to accumulate at the heat dissipation holes of the hot press body. The accumulation of dust seriously hinders heat dissipation, causing the internal temperature of the hot press body to rise continuously. The excessively high temperature accelerates the aging of the hot press body parts, which not only increases the maintenance cost of the equipment, but also frequently leads to equipment failure, reduces production efficiency, and affects the continuity of production.
[0004] On the other hand, during the hot pressing process, operators may accidentally touch the buttons on the hot press machine body. Once accidentally touched, the preset hot pressing parameters of the hot press machine will change, which directly affects the hot pressing effect, resulting in unqualified product quality, waste of raw materials and increased production costs. These problems need to be solved in order to improve the performance and reliability of the irregular curved surface laminating hot press machine.
[0005] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: During long-term use, the heating element of the hot press body generates heat for a long time. Due to the large amount of dust at the heat dissipation holes of the hot press body, the heat dissipation is slow, resulting in excessively high internal temperature of the hot press body and accelerated aging of the hot press body parts. Therefore, in order to solve the above problems, an irregular curved surface bonding hot press is proposed. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the heating elements generating heat for extended periods during long-term use of the hot press body, and the slow heat dissipation due to dust accumulation at the heat dissipation holes, leading to excessively high internal temperatures and accelerated aging of the hot press body components. Therefore, this invention proposes a hot press for bonding irregular curved surfaces.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a hot press for bonding irregular curved surfaces, comprising a hot press body, wherein a plurality of heat dissipation holes are provided on the surface of the hot press body, and a dustproof device is provided on the surface of the hot press body, the dustproof device comprising a fixed frame, the fixed frame being fixedly connected to the surface of the hot press body, a dustproof plate being slidably connected to the surface of the fixed frame, a rotating rod being rotatably connected to the surface of the fixed frame, and a baffle being fixedly connected to the arc surface of the rotating rod.
[0008] The effect achieved by the above-mentioned components is as follows: by setting up a dustproof device, the dust adhesion on the heat dissipation hole surface of the hot press body can be reduced. This avoids the situation where the heating element generates heat for a long time during the long-term use of the hot press body. Due to the large amount of dust at the heat dissipation hole of the hot press body, the heat dissipation is slow, which leads to the internal temperature of the hot press body being too high, causing the hot press body parts to age faster, thus improving the service life of the equipment.
[0009] Preferably, sliding rods are fixedly connected to both sides of the fixed frame, and irregularly shaped plates are slidably connected to the arc surfaces of the sliding rods.
[0010] The effect achieved by the above components is to restrict the rotation of the baffle. The operation is simple and convenient, allowing workers to quickly open the baffle and remove the dust cover.
[0011] Preferably, square blocks are fixedly connected to both sides of the fixed frame, and a limiting rod is slidably inserted into the square block, with a limiting block fixedly connected to one end of the limiting rod.
[0012] The aforementioned components achieve the following effect: the limiting block can restrict the movement of the irregularly shaped plate, preventing vibrations caused by workers disassembling the dustproof plate, which could lead to the irregularly shaped plate sliding, or collisions between the baffle and the irregularly shaped plate when workers close the baffle, resulting in damage to the baffle.
[0013] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are respectively fixedly connected to the fixed frame and the baffle.
[0014] The effect achieved by the above components is that the torsion spring's torque automatically opens the baffle while keeping it open, thus facilitating the removal of the dust cover by the staff.
[0015] Preferably, the surface of the hot press body is provided with a protective device, the protective device including a U-shaped frame, the U-shaped frame being fixedly connected to the surface of the hot press body, the surface of the U-shaped frame having two sliding holes, the surfaces of the two U-shaped frame sliding holes being slidably connected to a protective plate, the surface of the U-shaped frame having two fixed rods being fixedly connected to the surface, the arc surface of the fixed rods being slidably connected to an operating plate, the side of the operating plate near the U-shaped frame being fixedly connected to a plug rod, and the surface of the protective plate having two slots.
[0016] The effect achieved by the above-mentioned components is as follows: by setting up protective devices, the buttons on the hot press body can be protected, which avoids the situation where the hot press body is accidentally touched by the operator during product processing, causing the hot pressing parameters set by the hot press body to change, thereby resulting in the product quality of the hot press body being unqualified, thus improving the practicality of the equipment.
[0017] Preferably, the arc surface of the fixing rod is fitted with a spring, and the two ends of the spring are fixedly connected to the operating plate and the U-shaped frame, respectively.
[0018] The effect achieved by the above components is that the spring's rebound force automatically inserts the plug rod, while limiting the movement of the plug rod driven by the operating plate, thus improving the stability of the plug rod when fixing the protective plate.
[0019] Preferably, a groove is provided at the end of the fixing rod away from the U-shaped frame, and a blocking block is fixedly connected to the surface of the groove of the fixing rod.
[0020] The effect achieved by the above components is that the blocking block can restrict the movement of the control panel, preventing the control panel from moving too far and causing excessive deformation of the spring, which could lead to spring damage.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] 1. In this utility model, by setting a dustproof device, the effect of reducing dust adhesion to the heat dissipation holes of the hot press body is achieved. This avoids the situation where the heating element generates heat for a long time during the long-term use of the hot press body. Due to the large amount of dust at the heat dissipation holes of the hot press body, the heat dissipation is slow, which leads to the internal temperature of the hot press body being too high and causes the hot press body parts to age faster, thus improving the service life of the equipment.
[0023] 2. In this utility model, by setting a protective device, the buttons on the hot press body can be protected, which avoids the situation where the hot press body is accidentally touched by the operator during product processing, causing the hot pressing parameters set by the hot press body to change, thereby resulting in the product quality of the hot press body being unqualified, thus improving the practicality of the equipment.

[0031] Reference Figure 1As shown, this utility model provides a technical solution: a hot press for bonding irregular curved surfaces, including a hot press body 1. The surface of the hot press body 1 has several heat dissipation holes, and a dustproof device 2 is provided on the surface of the hot press body 1. By setting the dustproof device 2, the effect of reducing dust adhesion to the surface of the heat dissipation holes of the hot press body 1 is achieved. This avoids the situation where, during long-term use, the heating element of the hot press body 1 generates heat for an extended period. Due to the large amount of dust at the heat dissipation holes of the hot press body 1, the heat dissipation is slow, leading to excessively high internal temperatures of the hot press body 1 and accelerated aging of the components, thus improving the service life of the equipment. A protective device 3 is provided on the surface of the hot press body 1. By setting the protective device 3, the button of the hot press body 1 is protected, preventing accidental touches by workers during product processing, which could alter the set hot pressing parameters and cause the processed products to be of substandard quality, thus improving the practicality of the equipment.
[0032] The specific setup and function of its dustproof device 2 and protective device 3 will be explained below.
[0033] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the dustproof device 2 includes a fixed frame 201, which is fixedly connected to the surface of the hot press body 1. A dustproof plate 202 is slidably connected to the surface of the fixed frame 201. A rotating rod 203 is rotatably connected to the surface of the fixed frame 201. A baffle 204 is fixedly connected to the arc surface of the rotating rod 203. Sliding rods 205 are fixedly connected to both sides of the fixed frame 201. A shaped plate 206 is slidably connected to the arc surface of the sliding rod 205. During the use of the hot press body 1, dust and other impurities in the air are blocked by the dustproof plate 202. After prolonged use, dust may clog the dustproof plate 202. At this time, the operator can clean the dust on the surface of the dustproof plate 202 and move the shaped plate 206. The irregularly shaped plate 206 slides on the arc surface of the sliding rod 205. When the irregularly shaped plate 206 is completely detached from the surface of the baffle 204, the irregularly shaped plate 206 releases its fixation to the baffle 204. The baffle 204 is rotated, and when the baffle 204 is fully opened, the dustproof plate 202 is moved. The dustproof plate 202 slides on the surface of the fixed frame 201. When the dustproof plate 202 is completely detached from the surface of the fixed frame 201, the dustproof plate 202 is disassembled. At this time, the staff can clean the dust on the surface of the dustproof plate 202. After cleaning, the dustproof plate 202 is put back in its original position. Then the baffle 204 is rotated back to its original position, and the irregularly shaped plate 206 is pushed. When the irregularly shaped plate 206 moves to the surface of the baffle 204, the irregularly shaped plate 206 can fix the baffle 204, thus achieving the goal of restricting the baffle 205. The rotation effect of 04 is simple and convenient, allowing workers to quickly open the baffle 204 and remove the dustproof plate 202. Square blocks 207 are fixedly connected to both sides of the fixed frame 201. A limiting rod 208 is slidably inserted into the square block 207, and a limiting block 209 is fixedly connected to one end of the limiting rod 208. When workers need to remove the dustproof plate 202, they move the irregular plate 206. When the irregular plate 206 is completely detached from the surface of the baffle 204, they push the limiting rod 208, which drives the limiting block 209 to move. When the limiting block 209 moves between the irregular plate 206 and the fixed frame 201, the limiting block 209 restricts the movement of the irregular plate 206. Rotating the baffle 204 fully opens it, allowing workers to... After removing and cleaning the dustproof panel 202, close the baffle 204. Move the limiting rod 208 to move the limiting block 209 until the limiting block 209 no longer obstructs the movement of the irregularly shaped plate 206. Move the irregularly shaped plate 206 to the surface of the baffle 204. The limiting block 209 effectively restricts the movement of the irregularly shaped plate 206, preventing vibrations during the removal of the dustproof panel 202 that could cause the irregularly shaped plate 206 to slide. This also prevents the baffle 204 from colliding with the irregularly shaped plate 206 and causing damage when the baffle 204 is closed. The rotating rod 203 has two torsion springs 210 on its arc surface. The two ends of the torsion springs 210 are fixedly connected to the fixed frame 201 and the baffle 204, respectively. When the baffle 204 needs to be opened...The irregularly shaped plate 206 is moved. When the irregularly shaped plate 206 is completely detached from the surface of the baffle 204, the irregularly shaped plate 206 is released from its fixation to the baffle 204. The torque of the torsion spring 210 drives the baffle 204 to rotate, which in turn drives the rotating rod 203 to rotate until the baffle 204 is fully open. The torque of the torsion spring 210 achieves the effect of automatically opening the baffle 204 while keeping it in the open state, thus facilitating the removal of the dustproof plate 202 by the staff.
[0034] Reference Figure 5 and Figure 6As shown, specifically, the protective device 3 includes a U-shaped frame 31, which is fixedly connected to the surface of the hot press body 1. Two sliding holes are formed on the surface of the U-shaped frame 31, and protective plates 32 are slidably connected to the surfaces of the two sliding holes. Two fixing rods 33 are fixedly connected to the surface of the U-shaped frame 31, and an operating plate 34 is slidably connected to the arc surface of the fixing rods 33. A plug rod 35 is fixedly connected to the side of the operating plate 34 near the U-shaped frame 31. Two slots are formed on the surface of the protective plate 32, and a spring 36 is fitted onto the arc surface of the fixing rod 33. The two ends of the spring 36 are fixedly connected to the operating plate 34 and the U-shaped frame 31, respectively. When the operator needs to use the protective plate 32 to protect the buttons on the hot press body 1, the protective plate 32 is moved. The protective plate 32 slides across the surface of the sliding hole in the U-shaped frame 31. When the surface of the protective plate 32 contacts the insert rod 35, due to the unique shape of the insert rod 35 and the protective plate 32, the protective plate 32 will first press the insert rod 35. The insert rod 35 then moves the operating plate 34, stretching the spring 36. Continuing to move the protective plate 32, when it reaches the front of the buttons on the hot press body 1, the insert rod 35 is fully inserted into the surface of the slot in the protective plate 32, at which point the insert rod 35 can fix the protective plate. 32. The rebound force of spring 36 achieves the effect of automatically inserting the insertion rod 35, while limiting the movement of the insertion rod 35 driven by the operating plate 34, thus improving the stability of the insertion rod 35 when fixing the protective plate 32. The end of the fixing rod 33 away from the U-shaped frame 31 has a groove, and a blocking block 37 is fixedly connected to the surface of the groove of the fixing rod 33. When the operator needs to use the button of the hot press body 1, the operating plate 34 is moved, the spring 36 is stretched, and the operating plate 34 drives the insertion rod 35 to move. When the surface of the operating plate 34 contacts the blocking block 37, the operating plate 34 stops moving, and the insertion rod 35 is completely disengaged from the protective plate 32. On the surface of the groove, the insertion rod 35 releases the fixing of the protective plate 32. At this time, the protective plate 32 slides downward under the action of gravity. When the protective plate 32 is completely separated from the front of the button of the hot press body 1, the operator can use the button of the hot press body 1 normally. Release the operating plate 34, and the rebound force of the spring 36 drives the operating plate 34 to move until the operating plate 34 moves to the appropriate position. The blocking block 37 achieves the effect of restricting the movement of the operating plate 34, avoiding the situation where the operating plate 34 moves too far when the operator moves the operating plate 34, causing the spring 36 to deform excessively and be damaged.
[0035] Working principle: During use, dust and other impurities in the air are blocked by the dustproof plate 202. After prolonged use, dust may clog the dustproof plate 202. At this time, the operator can clean the dust off the surface of the dustproof plate 202 and move the shaped plate 206. The shaped plate 206 slides on the arc surface of the sliding rod 205. When the shaped plate 206 is completely detached from the surface of the baffle 204, the shaped plate 206 releases its fixation to the baffle 204. The torque of the torsion spring 210 drives the baffle 204 to rotate. The baffle 204 drives the rotating rod 203 to rotate until the baffle 204 is fully open, pushing the limit rod 208. The limit rod 208 drives the limit block 209 to move. When the limit block 209 moves between the shaped plate 206 and the fixed frame 201, the limit block 209 can restrict the movement of the shaped plate 206. At this time, the operator can move the dustproof plate 202. The fixed frame 201 slides on the surface. When the dustproof plate 202 is completely detached from the surface of the fixed frame 201, the dustproof plate 202 is disassembled. At this time, the staff can clean the dust on the surface of the dustproof plate 202. After cleaning, the dustproof plate 202 is put back in its original position. Then the baffle 204 is rotated back to its original position. The moving limit rod 208 drives the limit block 209 to move until the limit block 209 no longer blocks the movement of the irregular plate 206. The irregular plate 206 is pushed. When the irregular plate 206 moves to the surface of the baffle 204, the irregular plate 206 can fix the baffle 204. At this time, the effect of reducing dust adhering to the surface of the heat dissipation hole of the hot press body 1 is achieved. This avoids the situation where the heating element of the hot press body 1 generates heat for a long time during long-term use. Because there is a lot of dust at the heat dissipation hole of the hot press body 1, the heat dissipation is slow, which leads to the internal temperature of the hot press body 1 being too high, causing the parts of the hot press body 1 to age faster.
[0036] When the operator needs to use the protective plate 32 to protect the buttons on the hot press body 1, the protective plate 32 is moved. The protective plate 32 slides on the surface of the sliding hole in the U-shaped frame 31. When the surface of the protective plate 32 contacts the insert rod 35, due to the special shape of the insert rod 35 and the protective plate 32, the protective plate 32 will first squeeze the insert rod 35. The insert rod 35 drives the operating plate 34 to move, and the spring 36 is stretched. The protective plate 32 continues to move. When the protective plate 32 moves to the front of the buttons on the hot press body 1, the insert rod 35 is fully inserted into the surface of the slot in the protective plate 32. At this time, the insert rod 35 can fix the protective plate 32. When the operator needs to use the buttons on the hot press body 1, the operating plate 34 is moved. The spring 36 is stretched, and the operating plate 34 drives the insert rod 35 to move. When the surface of the operating plate 34... When the operating plate 34 contacts the blocking block 37, it stops moving, and the insert rod 35 completely disengages from the surface of the slot in the protective plate 32. The insert rod 35 releases its fixation to the protective plate 32, and the protective plate 32 slides downward under the force of gravity. When the protective plate 32 is completely disengaged from the front of the button on the hot press body 1, the operator can use the button on the hot press body 1 normally. Releasing the operating plate 34 causes the spring 36 to move the operating plate 34 until it moves to the appropriate position. At this point, the button on the hot press body 1 is protected, preventing the operator from accidentally touching the button on the hot press body 1 while processing products, which could cause the hot pressing parameters set on the hot press body 1 to change, resulting in unqualified product quality.
