Description

Technical Field

[0001] This utility model relates to the technical field of vulcanization heating, and in particular to a heating device for a conveyor belt vulcanization joint. Background Technology

[0002] In industrial production, conveyor belts are key equipment for material transportation, and their performance directly affects production efficiency and cost. The vulcanized joint of the conveyor belt is a crucial element in ensuring its continuous operation; the quality of the vulcanized joint determines the service life and operational stability of the conveyor belt.

[0003] Traditional conveyor belt vulcanizing joint heating devices have several shortcomings. Firstly, it's difficult to achieve uniform pressure and precise heating of the conveyor belt vulcanizing joint during the heating process.

Secondly, existing heating devices lack an effective shaping mechanism after vulcanization, failing to ensure rapid and stable shaping of the hot-melted conveyor belt vulcanized joint. The joint is prone to deformation during cooling, reducing its precision and reliability. Utility Model Content

[0048] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0049] like Figures 1 to 4 As shown, the present invention provides a heating device for a conveyor belt vulcanizing joint, comprising:

[0050] Support base 1, movable and set on the ground;

[0051] Heating mechanism 2, mounted on support base 1, is used to pressurize and heat the vulcanized joint of the conveyor belt;

[0052] Two shaping mechanisms 3 are symmetrically arranged on the support base 1 and are used to shape the vulcanized joint of the conveyor belt after hot melting.

[0053] The heating mechanism 2 includes:

[0054] Heating bracket 21 is fixedly installed on support base 1;

[0055] Two main guide pillars 22 are symmetrically and vertically arranged in the heating bracket 21;

[0056] The upper pressure plate 23 is slidably mounted on the two main guide posts 22.

[0057] The heating substrate 24 is slidably mounted on the two main guide posts 22.

[0058] Two shock-absorbing components are disposed between the upper pressure plate 23 and the heating base plate 24 to connect the upper pressure plate 23 and the heating base plate 24 and to dampen the heating base plate 24.

[0059] The lower pressure plate 25 is slidably mounted on the two main guide posts 22.

[0060] Two heating plates 26 are respectively disposed on the heating base plate 24 and the lower pressure plate 25;

[0061] Two sets of linkage components are respectively set on both sides of the heating bracket 21, which are used to drive the heating base plate 24 and the lower pressure plate 25 to slide up and down in a linkage manner.

[0062] The linkage components include:

[0063] Linkage plate 27 is mounted on heating bracket 21 with its own center as the axis of rotation. Linkage plate 27 is set in a rhombus shape.

[0064] Two linkage rods 28 are respectively oscillatingly connected to both ends of the linkage plate 27;

[0065] Two transmission plates 29 are fixedly connected to the upper pressure plate 23 and the lower pressure plate 25 respectively, and the transmission plates 29 are hinged to the linkage rod 28.

[0066] The working process and principle of the device are as follows: The conveyor belt joint to be vulcanized is placed between the heating plates 26 of the heating mechanism 2, ensuring the joint is correctly positioned; the overall position of the device is adjusted so that the shaping mechanism 3 can be easily moved to the welding position after heating and welding; the heating device is started, and the linkage assembly begins to work; the linkage disc 27 rotates around its own center axis, driving the two linkage rods 28 to swing; the swing of the linkage rods 28 is transmitted to the upper pressure plate 23 and the lower pressure plate 25 through the transmission plate 29, causing them to move along the main guide post 22 to pressurize the conveyor belt joint; the heating plate 26 begins to heat, transferring heat to the joint to achieve uniform heating; the shock absorption assembly acts as a buffer between the upper pressure plate 23 and the heating base plate 24, ensuring the stability of the pressurization process; after the pressurization and heating are completed, the linkage assembly continues to work, causing the upper pressure plate 23 and the lower pressure plate 25 to separate, releasing the pressure on the joint; at this point, the joint has completed vulcanization and welding; next, by moving the support base 1, the entire device is moved horizontally to the shaping position, aligning the two shaping mechanisms 3 with the welding position. The shaping mechanism 3 begins operation, clamping the welded joint. Through mechanical clamping force, the shaping mechanism 3 maintains a stable shape for the joint during cooling, preventing deformation. After shaping, the shaping mechanism 3 releases the clamping force, removing the vulcanized conveyor belt joint. The linkage assembly enables synchronous movement of the upper pressure plate 23 and the lower pressure plate 25, thus applying uniform pressure to the conveyor belt joint. Heating plates 26 are respectively positioned on the heating base plate 24 and the lower pressure plate 25, ensuring uniform heating of the joint while applying pressure, improving the vulcanization effect. The symmetrical arrangement and mobility of the shaping mechanism 3 ensure that the joint can be quickly and stably shaped after hot melting. The shaping mechanism 3 uses mechanical clamping force or cooling to fix the shape of the joint, preventing deformation during cooling and improving the precision and reliability of the joint. The linkage assembly achieves uniform pressure and precise heating of the conveyor belt joint, and the movable shaping mechanism ensures rapid and stable shaping of the joint after hot melting, improving the quality and stability of the vulcanized joint and extending the overall service life of the conveyor belt.

[0067] It also includes four omnidirectional casters 11, which are fixedly installed at the bottom of the support base 1 in a four-corner shape. The four omnidirectional casters 11 are fixedly installed at the bottom of the support base 1 in a four-corner shape, so that the entire device can be easily moved and positioned on the ground. The conveyor belt joint to be vulcanized is placed between the heating plates 26 of the heating mechanism 2 to ensure that the joint is in the correct position. The overall position of the device is adjusted by the omnidirectional casters 11 so that the shaping mechanism 3 can be easily moved to the welding position after the heating and welding are completed. The entire device can be easily moved horizontally to the shaping position by the omnidirectional casters 11 so that the two shaping mechanisms 3 are aligned with the welding position. The conveyor belt vulcanization joint heating device behind the four omnidirectional casters 11 not only realizes uniform pressure and precise heating of the conveyor belt joint, but also ensures that the joint is quickly and stably shaped after heat melting through the movable shaping mechanism and omnidirectional casters, while improving the flexibility and production efficiency of the device.

[0068] The damping components include:

[0069] The shock-absorbing guide post 2a is fixedly installed on the heating base plate 24, and the main body of the shock-absorbing guide post 2a is slidably inserted into the upper pressure plate 23.

[0070] The elastic spring 2b is sleeved on the outer end of the shock-absorbing guide post 2a, and the elastic spring 2b is disposed between the upper pressure plate 23 and the heating base plate 24.

[0071] The shock-absorbing guide post 2a serves as a guide and support element, ensuring that the upper pressure plate 23 maintains a stable movement trajectory during its up-and-down sliding. The elastic spring 2b, as an elastic element, provides shock absorption and cushioning. When the linkage assembly operates, the linkage disc 27 rotates, causing the linkage rod 28 to swing, which in turn pushes the upper pressure plate 23 and the lower pressure plate 25 along the main guide post 22 towards the heating base plate 24 via the transmission plate 29, applying pressure to the conveyor belt joint. During this process, the upper pressure plate 23 slides downward along the shock-absorbing guide post 2a, compressing the elastic spring 2b. The elastic spring 2b absorbs energy during compression, providing a cushioning effect and preventing the upper pressure plate 23 from generating excessive impact force on the heating base plate 24 and the joint. After the upper pressure plate 23 and the lower pressure plate 25 apply sufficient pressure to the joint, they maintain this pressure for a period of time to ensure sulfur content. The vulcanization process proceeds smoothly. During this stage, the elastic spring 2b is in a compressed state, continuing to provide stable support force to ensure that the pressure of the heating plate 24 on the joint remains constant. The combination of the damping guide post 2a and the elastic spring 2b constitutes a damping system. During the pressurization and depressurization processes, the elastic spring 2b can absorb and release energy, reducing the impact and vibration of the upper pressure plate 23 on the heating plate 24 and the joint, protecting the joint from damage. During the pressurization process, the buffering effect of the elastic spring 2b causes the pressure of the upper pressure plate 23 on the joint to gradually increase, avoiding excessive instantaneous impact force. During the depressurization process, the elastic force of the elastic spring 2b causes the upper pressure plate 23 to gradually rise, ensuring that the joint remains stable during the depressurization process, protecting the joint from the impact and vibration, and improving the quality and stability of the vulcanized joint.

[0072] It also includes a limiting ring 2c, which is fastened to the top of the shock-absorbing guide post 2a to limit the upper pressure plate 23. The main function of the limiting ring 2c is to limit the sliding range of the upper pressure plate 23 on the shock-absorbing guide post 2a. The limiting ring 2c is fastened to the top of the shock-absorbing guide post 2a to ensure that the upper pressure plate 23 will not detach from the shock-absorbing guide post 2a when sliding upward. The limiting ring 2c does not directly participate in the pressurization process at this stage, but it serves as the upper limit of the sliding range of the upper pressure plate 23, preventing the upper pressure plate 23 from detaching from the shock-absorbing guide post 2a under abnormal conditions, protecting the safety of equipment and operators, and improving the reliability and durability of the conveyor belt vulcanizing joint heating device.

[0073] The shaping mechanism 3 includes:

[0074] The shaping bracket 31 is fixedly installed on the support base 1;

[0075] Adjusting slider 32 is slidably mounted in shaping bracket 31;

[0076] Screw 33 is rotatably mounted on the shaping bracket 31, and screw 33 is threadedly engaged with the adjusting slider 32;

[0077] The clamp mounting bracket 34 is horizontally slidably mounted on the shaping bracket 31, and the clamp mounting bracket 34 is fixedly connected to the adjusting slider 32.

[0078] A shaping clamp 35 is fixedly installed on a clamp mounting bracket 34.

[0079] Before the shaping process, the shaping mechanism 3 is in its initial state, and the distance between the shaping clamps 35 is pre-adjusted according to the width of the conveyor belt and the size of the vulcanizing joint. After heating, the entire device moves horizontally via the universal casters 11, moving the shaping mechanism 3 to the welding position. The position of the shaping clamps 35 needs to be finely adjusted according to the specific position and size of the vulcanizing joint. By rotating the screw 33, since the screw 33 is threadedly engaged with the adjusting slider 32, the adjusting slider 32 slides horizontally along the guide rail of the shaping bracket 31. The clamp mounting bracket 34 is fixedly connected to the adjusting slider 32, and therefore also slides along with the adjusting slider 32, thereby adjusting the position of the shaping clamps 35. When the shaping clamps 35 are adjusted... Once in the appropriate position, the vulcanized joint of the conveyor belt after hot melting is clamped. The shaping clamp 35 provides a stable clamping force to ensure that the vulcanized joint maintains its shape during cooling and prevents deformation. During the shaping process, the shaping clamp 35 is held in the clamping state for a period of time as needed to ensure that the vulcanized joint is fully shaped. After shaping is completed, the screw 33 is rotated to loosen the shaping clamp 35 and move the shaping mechanism 3 back to the initial position or prepare for the next shaping process. The shaping mechanism 3 achieves precise adjustment of the position of the shaping clamp 35 through the threaded engagement of the screw 33 and the adjusting slider 32. By clamping the vulcanized joint of the conveyor belt after hot melting, it ensures that it maintains its shape during cooling, thereby improving the accuracy and reliability of the vulcanized joint.

[0080] A handwheel is provided at the end of the screw 33; the screw 33 is fixed at the end of the screw 33, providing a manual operation interface for easy rotation by the operator; the handwheel provides a convenient manual operation interface, allowing the operator to easily rotate the screw 33 without using additional tools or equipment; the shaping mechanism 3 is adjustable, and by rotating the handwheel to drive the screw 33 to rotate, the position of the shaping clamp 35 can be easily adjusted to adapt to conveyor belt vulcanization joints of different widths and sizes; the handwheel makes the operation process more convenient and efficient.

[0081] The shaping mechanism 3 also includes:

[0082] The first cylinder 36 is fixedly mounted on the clamp mounting bracket 34;

[0083] The second cylinder 37 is mounted on the clamp mounting bracket 34 and its lifting and lowering are controlled by the first cylinder 36.

[0084] The fan bracket 38 is horizontally movable and mounted on the clamping plate mounting bracket 34, and its horizontal movement is controlled by the second cylinder 37.

[0085] Cooling fan 39 is fixedly mounted on fan bracket 38;

[0086] The shaping clamp 35 closes to hold the hot-melted vulcanized joint of the conveyor belt. After clamping, the first cylinder 36 is activated, pushing the second cylinder 37 to rise or fall to the appropriate position. The lifting and lowering movement of the second cylinder 37 drives the fan bracket 38 to move up and down. Then, the second cylinder 37 controls the fan bracket 38 to move horizontally, so that the cooling fan 39 is aligned with the vulcanized joint. The cooling fan 39 is started, blowing out cold air to quickly cool the hot-melted vulcanized joint of the conveyor belt. The cold air helps the vulcanized joint to quickly set, reducing deformation during the cooling process and improving the accuracy and reliability of the joint. The transmission of the cylinder and the cooling effect of the cooling fan work together to improve the setting efficiency and the joint quality, realizing the rapid and accurate clamping and cooling setting of the vulcanized joint of the conveyor belt, thus improving the setting efficiency and the joint quality.

[0087] A counterweight is provided on the support base 1; the counterweight is fixedly installed on the support base 1 to increase the weight and stability of the entire device; the presence of the counterweight makes the entire device more stable during the heating process, reducing displacement or tilting caused by external forces or vibrations; although the counterweight increases the weight of the device, it also improves its stability during movement, reducing damage caused by bumps or collisions; during heating, vulcanization and shaping, the counterweight helps resist external forces or vibrations, ensuring that the device remains stable; the counterweight lowers the center of gravity of the device, improving its anti-overturning ability; even on uneven ground or under lateral forces, the counterweight helps the device remain stable and prevents overturning.

[0088] The heating device for the vulcanized joint of the conveyor belt of this utility model has common mechanical methods in terms of installation, connection or setting. It can be implemented as long as it can achieve its beneficial effect.

[0089] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
