Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt processing technology, specifically a hot pressing device. Background Technology

[0002] In the production and processing of conveyor belts, hot pressing is one of the key processes, used to connect the two ends of the conveyor belt together to form a continuous conveyor belt loop. Traditional conveyor belt hot pressing devices have some problems in practical applications. Typically, when performing hot pressing operations, the two ends of the conveyor belt are simply placed on the platform under the hot press without a dedicated fixing device to ensure the stability of the conveyor belt during the hot pressing process. Because the hot press generates a large pressure and a certain impact force during the pressing process, the conveyor belt is easily affected by these external forces and may shift without effective fixing. This shift will lead to inaccurate hot pressing position, which in turn affects the bonding strength and sealing of the conveyor belt joint. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a hot pressing device, which solves the problem that in traditional hot pressing devices, when the two ends of the conveyor belt are simply placed on the platform under the hot press, the conveyor belt is easily displaced by the large pressure and impact force generated by the hot press during the pressing process, without effective fixation. This displacement will lead to inaccurate hot pressing position, which in turn affects the connection quality of the conveyor belt.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hot pressing device, including a base, a support rod fixedly connected to one end of the base, a crossbeam fixedly connected to one side of the support rod near its top, a hot press machine located below the crossbeam, four fixing mechanisms located at the four corners of the hot press machine, each fixing mechanism including an outer sleeve rod fixedly connected to the side of the hot press machine, a sliding rod slidably connected to the end of the outer sleeve rod, two columns fixedly connected to opposite sides of the inner sides of the outer sleeve rod and the sliding rod, compression springs fitted around the two columns, a fixing block fixedly connected to the bottom of the sliding rod, and two fixed supports symmetrically fixedly installed above the crossbeam, telescopic rods fixedly connected inside the fixed supports, the ends of the two telescopic rods penetrating the crossbeam and connecting to the top of the hot press machine.

[0005] As a further embodiment of this utility model: a placement platform is fixedly connected to one side of the support rod near its middle part, a conveyor belt is provided above the placement platform, the conveyor belt is sleeved on the outside of the placement platform, and the position of the hot press corresponds to the connection end of the conveyor belt.

[0006] As a further embodiment of this utility model: two support plates are symmetrically fixedly connected to the upper end of the base away from the support rod. Two flattening mechanisms are respectively provided above the two support plates. The flattening mechanism includes a support block. The support block is fixedly connected to the top of the support plate. The top of the support block is provided with a pillar.

[0007] As a further embodiment of this utility model: the support column passes through the top of the support block and slides on its top, the bottom end of the support column is fixedly connected to a pressure block, the top end of the support column is fixedly connected to a baffle, and the outer wall of the support column is sleeved with a return spring above the pressure block.

[0008] As a further embodiment of this utility model: a flattening roller is attached to the top of the placement platform, the flattening roller is rotatably connected between two pressure blocks, and the flattening roller is located at the end of the placement platform away from the support rod.

[0009] As a further embodiment of this utility model: two limiting grooves are respectively opened on both sides of the support block, and the limiting grooves are through-type designs.

[0010] As a further embodiment of this utility model: two limiting blocks are symmetrically fixedly connected to both sides of the pressure block, and the two limiting blocks slide in two limiting grooves respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This hot pressing device, through the setting of a fixing mechanism, ensures that when the hot press is started and the telescopic rod drives the hot press to press down, the fixing block in the fixing mechanism will first contact the conveyor belt. Under the pressure of the hot press, the sliding rod slides and contracts on the inner wall of the outer rod, causing the compression spring to be tightened and generating elastic force. Under the action of this elastic force, the fixing block tightly presses the conveyor belt and fixes it in the predetermined position. In this way, it can ensure that the conveyor belt is stable and does not move during the hot pressing process, avoiding the impact on processing accuracy due to the displacement of the conveyor belt, thereby ensuring the accuracy and reliability of the hot pressing operation and improving the quality of the conveyor belt after hot pressing.

[0013] 2. This hot pressing device, by setting a flattening mechanism, allows the conveyor belt to be removed from the top of the placement platform. The flattening roller rotates between two pressure blocks under the friction of the conveyor belt, while simultaneously being squeezed upwards by the thickness of the conveyor belt. This causes the pressure blocks and supports to slide within the support block and squeeze the return spring. The elastic force of the return spring then drives the flattening roller downwards through the pressure blocks, flattening the hot-pressed joint of the conveyor belt. This structural operation can automatically adjust the pressure of the flattening roller according to the thickness of the conveyor belt, avoiding excessive squeezing damage to the conveyor belt, while ensuring a flat joint. This improves the adaptability of the device to conveyor belts of different specifications and the appearance quality and performance of the conveyor belt after hot pressing.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-5 As shown, this utility model provides a technical solution: a hot pressing device, including a base 1, a support rod 2 fixedly connected to one end of the base 1, a crossbeam 3 fixedly connected to one side of the support rod 2 near its top, a hot press 4 provided below the crossbeam 3, and four fixing mechanisms 5 respectively provided at the four corners of the hot press 4. The fixing mechanism 5 includes an outer rod 501, which is fixedly connected to the side of the hot press 4. A sliding rod 502 is slidably connected to the end of the outer rod 501. Through the cooperation between the outer rod 501 and the sliding rod 502, the sliding rod 502 can slide and retract on the inner wall of the outer rod 501 when the hot press 4 is pressed down, so that the hot press 4 can perform hot pressing operation according to the predetermined pressing speed and pressure without being subject to additional resistance, thus ensuring the stability of the hot pressing process.

[0022] Two uprights 503 are fixedly connected to opposite sides of the inner sides of the outer rod 501 and the slide rod 502, respectively. Compression springs 504 are fitted over the two uprights 503. A fixing block 505 is fixedly connected to the bottom of the slide rod 502. Two fixed supports 6 are symmetrically fixedly installed above the crossbeam 3. Telescopic rods 7 are fixedly connected inside the fixed supports 6. The ends of the two telescopic rods 7 pass through the crossbeam 3 and connect to the top of the hot press 4. Because of the fixing mechanism 5, during the hot pressing process, the fixing block 505 in the fixing mechanism 5 contacts the conveyor belt 9 before the hot press 4. As the heat... When the press 4 presses down, the slide bar 502 slides and retracts on the inner wall of the outer sleeve bar 501, and the compression spring 504 begins to tighten. Under the elastic force of the compression spring 504, the slide bar 502 and the fixing block 505 press the conveyor belt 9 and fix it in the predetermined position to ensure that the conveyor belt 9 will not shift during the hot pressing process, thereby ensuring the accuracy of processing. A placement table 8 is fixedly connected to one side of the support rod 2 near the middle. The conveyor belt 9 is provided above the placement table 8 and is sleeved on the outside of the placement table 8. The position of the hot press 4 corresponds to the connection end of the conveyor belt 9.

[0023] Two support plates 10 are symmetrically fixedly connected to the upper end of the base 1, away from the support rod 2. Two flattening mechanisms 11 are respectively provided above the two support plates 10. Each flattening mechanism 11 includes a support block 1101, which is fixedly connected to the top of the support plate 10. A support column 1102 is provided at the top of the support block 1101, passing through the top of the support block 1101 and sliding at its top. A pressing block 1103 is fixedly connected to the bottom end of the support column 1102, and a pressure block 1103 is fixedly connected to the top end of the support column 1102. A return spring 1105 is sleeved on the outer wall of the baffle 1104 and the support column 1102 above the pressure block 1103. Because of the return spring 1105, when the conveyor belt 9 is thicker, the return spring 1105 will be compressed more accordingly. When the conveyor belt 9 is thinner, the compression of the return spring 1105 is smaller. The flattening roller 1106 can also provide appropriate pressure to flatten the joint of the conveyor belt 9, avoid excessive squeezing damage to the conveyor belt 9, and improve the adaptability of the device to conveyor belts 9 of different specifications.

[0024] A flattening roller 1106 is attached to the top of the placement platform 8. The flattening roller 1106 is rotatably connected between two pressure blocks 1103. The flattening roller 1106 is located at the end of the placement platform 8 away from the support rod 2. Because a flattening mechanism 11 is provided, when the conveyor belt 9 passes through the flattening mechanism 11 after hot pressing, the flattening roller 1106 rotates between the two pressure blocks 1103 under the friction of the conveyor belt 9, and will move upward due to the compression of the thickness of the conveyor belt 9. The elastic force of the return spring 1105 drives the flattening roller 1106 to press down again, flattening the hot-pressed joint of the conveyor belt 9 and eliminating wrinkles or unevenness that may occur during the hot pressing process. To achieve a smooth surface, two limiting grooves 1107 are respectively opened on both sides of the support block 1101, and two limiting blocks 1108 are symmetrically fixedly connected to both sides of the pressing block 1103. The two limiting blocks 1108 slide in the two limiting grooves 1107 respectively. Through the cooperation between the limiting blocks 1108 and the limiting grooves 1107, the pressing block 1103 drives the limiting blocks 1108 on both sides to slide in the two limiting grooves 1107 during the sliding process. This can limit the movement range of the pressing block 1103 and prevent the flattening roller 1106 from shifting position or rotating unevenly due to external force, thereby improving the working reliability of the flattening mechanism 11.

[0025] The working principle of this utility model is as follows: When using this device, the conveyor belt 9 to be processed is first sleeved on the placement platform 8. The first and second ends of the conveyor belt 9 are stacked on top of the placement platform 8 and below the hot press 4. When hot pressing begins, the hot press 4 is started, and the two telescopic rods 7 synchronously drive the hot press 4 to press down. The four fixing mechanisms 5 at the four corners of the hot press 4 press down together with the hot press 4. During the pressing process, the fixing block 505 in the fixing mechanism 5 contacts the conveyor belt 9 before the hot press 4. As the hot press 4 presses down, the slide rod 502 slides and contracts on the inner wall of the outer rod 501, and the compression spring 504 tightens to generate elastic force. Under the elastic force of the compression spring 504, the fixing block 505 presses the conveyor belt 9 and fixes it in the predetermined position. When the hot press 4 contacts the conveyor belt 9, the hot press 4 heats the conveyor belt 9. The component heats and applies sufficient pressure to the connecting end of the conveyor belt 9, making the connection of the conveyor belt 9 tightly bonded and performing hot pressing treatment. After hot pressing is completed, the conveyor belt 9 is pulled to remove it from the placement platform 8. During the process of the conveyor belt 9 being pulled, the connection of the first and second ends of the conveyor belt 9 will pass through the flattening mechanism 11. The flattening roller 1106 in the flattening mechanism 11 will be squeezed upward by the conveyor belt 9, causing the pressure block 1103 and the support column 1102 to slide in the support block 1101 and squeeze the return spring 1105. The elastic force of the return spring 1105 will again drive the flattening roller 1106 to press down through the pressure block 1103, so that the flattening roller 1106 presses down evenly, flattening the hot pressing connection of the conveyor belt 9, ensuring that the connection of the conveyor belt 9 is flat, and completing the hot pressing treatment of the conveyor belt 9.
