Description

Technical Field

[0001] This utility model relates to the field of conveyor belt forming technology, and in particular to a highly adaptable automatic pressure-adjustable conveyor belt forming device. Background Technology

[0002] In the conveyor belt forming process, the calender is a key piece of equipment for realizing the composite of rubber and reinforcing materials and controlling the thickness and precision of the materials. Its core function is to process rubber or plastic materials into sheets of a specific thickness and to achieve precise bonding with reinforcing materials such as fabrics and steel wire ropes, so as to provide qualified composite substrates for subsequent forming processes.

[0003] Chinese Patent No. 202121730289.4 discloses a novel calender for the production and processing of rubber conveyor belts, comprising a fixed support plate and a connecting pipe. The connecting pipe is provided on one side of the fixed support plate, and an adjustment knob is provided on one side of the connecting pipe. A fixing hole is provided on the surface of the adjustment knob, and a fixing rod is provided inside the fixing hole. Then, the drive motor is started, and the transmission shaft on one side of the drive motor drives the pressure pipe. The two pressure pipes rotate and process the rubber conveyor belt by extrusion. After long-term processing of the conveyor belt, due to frictional heat, high temperatures are generated on the surface of the rubber conveyor belt and the pressure pipe. The pressurization pump is started to pressurize the cooling water in the cooling tank and add the cooling water into the connecting pipe through a hose. The cooling water is sprayed onto the surface of the pressure pipe through an atomizing nozzle at the top of the guide pipe on the surface of the connecting pipe, reducing the temperature of the pressure pipe and the surface of the rubber conveyor belt, reducing the adhesion between the conveyor belt and the calender, and improving the efficiency of the calender in processing the conveyor belt.

[0004] When using the above technical solution, the tension of the material cannot be adjusted, which can easily lead to accumulation and blockage during material transmission, affecting the processing effect of the material. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a highly adaptable pressure-adjustable conveyor belt forming device. Through a tension adjustment mechanism, it solves the problem of material tension not being adjustable, which easily leads to accumulation and blockage during material transmission.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly adaptable pressure-adjustable conveyor belt forming device, comprising a calendering forming apparatus; the calendering forming apparatus consists of a worktable, guide wheels, a tension adjusting mechanism, and a fixed frame; the guide wheels are mounted on the left side of the upper end of the worktable via bearing seats at both ends; the fixed frame is located on the right side of the upper end of the worktable; a support and adjusting mechanism is installed around the fixed frame and between it and the worktable; a distance measuring mechanism is installed between the front end of the fixed frame and the front end of the worktable; an upper calendering mechanism is installed on the upper side of the fixed frame; a lower calendering mechanism is installed on the upper side of the worktable; the tension adjusting mechanism is installed on the upper side of the worktable between the guide wheels and the fixed frame; and a tension adjusting wheel is installed on the upper side of the tension adjusting mechanism.

[0007] Furthermore, both the upper and lower calendering mechanisms consist of two pressure rollers, a power mechanism, and a transmission mechanism. The front end of the pressure rollers is mounted on the rear end of the power mechanism, the power mechanism is mounted on the front end of the fixed frame and the front end of the worktable, and the transmission mechanism is mounted on the rear end of the pressure rollers.

[0008] Furthermore, the power mechanism consists of an electric motor and a transmission, with the electric motor mounted at the front end of the transmission.

[0009] Furthermore, the transmission mechanism consists of a synchronous belt and a synchronous pulley, with the synchronous pulley mounted at the rear end of the pressure roller and the synchronous belt meshing with the outer side of the synchronous pulley.

[0010] Furthermore, the ranging mechanism consists of a ruler and an electronic dial. The ruler is mounted on the front end of the fixed frame, and the electronic dial is mounted on the front end of the workbench. The bottom end of the ruler is slidably mounted inside the electronic dial. A display is mounted on the upper side of the front end of the electronic dial, and control buttons are mounted below the display on the front end of the electronic dial.

[0011] Furthermore, the tension adjustment mechanism consists of a mounting frame, a guide rod, a spring, and a slider. The mounting frame is installed at the front and rear ends of the left side of the upper end of the workbench. The guide rod is installed inside the mounting frame.

The pressure sensor is installed on the upper side of the telescopic rod, and the telescopic rod is installed at the front and rear ends of the left and right sides of the worktable.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The tension adjustment mechanism is the key to ensuring uniform force on the raw material. When tension fluctuations occur during the conveying process, the tension adjustment wheel can adjust the tension of the raw material by adapting its own position and cooperating with relevant components. This avoids uneven tension causing wrinkles or excessive stretching of the raw material, which in turn affects the uniformity of thickness after calendering.

[0016] 2. During use, the pressure sensor of the support adjustment mechanism monitors the pressure on the telescopic rod in real time. When the pressure exceeds or falls below the set range, it sends a signal to the control system. The control system then adjusts the telescopic rod's extension and retraction to keep the pressure within a suitable range during the calendering process, ensuring the calendering effect and safe operation of the equipment. At the same time, the support adjustment mechanism can make the fixed frame bear force evenly, ensuring the stability of the calendering mechanism and further improving the quality of the conveyor belt forming.

[0024] Example 1

[0025] like Figure 1-4 As shown, this embodiment provides a highly adaptable pressure-adjustable automatic conveyor belt forming device, including a calendering forming device 1. The calendering forming device 1 consists of a worktable 2, guide wheels 3, a tension adjusting mechanism 5, and a fixed frame 24. The guide wheels 3 are mounted on the upper left side of the worktable 2 through shaft seats at both ends. The fixed frame 24 is located on the upper right side of the worktable 2. A support adjusting mechanism 23 is installed around the fixed frame 24 and between it and the worktable 2. A distance measuring mechanism 15 is installed between the front end of the fixed frame 24 and the front end of the worktable 2. An upper calendering mechanism 6 is installed on the upper side of the fixed frame 24. A lower calendering mechanism 9 is installed on the upper side of the worktable 2. The tension adjusting mechanism 5 is installed on the upper side of the worktable 2 between the guide wheels 3 and the fixed frame 24. A tension adjusting wheel 4 is installed on the upper side of the tension adjusting mechanism 5.

[0026] Preferably, both the upper calendering mechanism 6 and the lower calendering mechanism 9 consist of two pressure rollers 25, a power mechanism 20, and a transmission mechanism 26. The front end of the pressure roller 25 is installed at the rear end of the power mechanism 20, which is installed at the front end of the fixed frame 24 and the front end of the worktable 2. The transmission mechanism 26 is installed at the rear end of the pressure roller 25. The two pressure rollers 25 are positioned correspondingly at the upper and lower positions to form a calendering channel. When the conveyor belt material passes between the two pressure rollers 25, it completes the forming process under pressure. The power mechanism 20 provides rotational power to the pressure rollers 25, thereby driving the pressure rollers 25 to rotate and realize the continuous conveying and calendering of the conveyor belt. The transmission mechanism 26 ensures that the two pressure rollers 25 in the same mechanism rotate synchronously, avoiding scratches or uneven calendering on the surface of the conveyor belt due to differences in rotation speed, and ultimately ensuring the uniformity of the thickness and the flatness of the surface of the conveyor belt.

[0027] Preferably, the power mechanism 20 consists of an electric motor 22 and a gearbox 21. The electric motor 22 is installed at the front end of the gearbox 21. The electric motor 22 outputs rotational torque as a power source. Through the transmission connection with the gearbox 21, the gearbox 21 can precisely adjust the speed and torque output by the electric motor 22 according to the material and thickness of the conveyor belt and the requirements of the calendering process, so that the pressure roller 25 obtains a suitable rotational speed and pressure, which not only ensures that the calendering effect meets the process standards, but also avoids damage to the conveyor belt or overload of the equipment due to improper power output.

[0028] Preferably, the transmission mechanism 26 consists of a synchronous belt 27 and a synchronous pulley 28. The synchronous pulley 28 is installed at the rear end of the pressure roller 25, and the synchronous belt 27 is engaged with the outer side of the synchronous pulley 28. The synchronous pulley 28 is fixedly connected to the rear end of the pressure roller 25 and rotates together with the pressure roller 25. The toothed structure on the inner side of the synchronous belt 27 precisely meshes with the toothed groove on the outer side of the synchronous pulley 28. When one of the pressure rollers 25 rotates under the drive of the power mechanism 20, the synchronous belt 27 can drive the other synchronous pulley 28 and the corresponding pressure roller 25 to rotate at the same speed, ensuring that the linear speed of the two pressure rollers 25 is consistent, thereby avoiding the conveyor belt from shifting or deforming due to uneven force during the calendering process.

[0029] Preferably, the ranging mechanism 15 consists of a ruler 17 and an electronic dial 16. The ruler 17 is installed at the front end of the fixed frame 24, and the electronic dial 16 is installed at the front end of the worktable 2. The bottom end of the ruler 17 is slidably installed inside the electronic dial 16. A display 18 is installed on the upper side of the front end of the electronic dial 16, and a control button 19 is installed below the display 18 at the front end of the electronic dial 16. The ruler 17 moves synchronously with the fixed frame 24. When the position of the fixed frame 24 is adjusted, the bottom end of the ruler 17 slides inside the electronic dial 16. The electronic dial 16 accurately detects the displacement of the ruler 17 through an internal sensor and converts the measurement data into an electrical signal, which is transmitted to the display 18 to intuitively display the current spacing of the pressure rollers 25. The operator can perform operations such as clearing data and switching units through the control button 19 to achieve precise control of the spacing of the pressure rollers 25, ensure that the calendering thickness meets the process requirements, and improve the adjustment accuracy and ease of operation of the equipment.

[0030] Preferably, the tension adjustment mechanism 5 consists of a mounting frame 14, a guide rod 13, a spring 12, and a slider 11. The mounting frame 14 is installed at the front and rear ends of the upper left side of the workbench 2. The guide rod 13 is installed inside the mounting frame 14. The slider 11 is slidably installed inside the mounting frame 14 on the upper side of the guide rod 13. The spring 12 is installed inside the mounting frame 14 on the outer side of the guide rod 13 at the bottom end of the slider 11. The tension adjustment wheel 4 is rotatably installed between the sliders 11. The mounting frame 14 provides support for the entire mechanism. The guide rod 13 guides the movement of the slider 11. When the conveyor belt tension increases, it will drive the tension adjustment wheel 4 to move upward. At this time, the slider 11 slides upward along the guide rod 13 and compresses the spring 12. The reverse elastic force generated by the spring 12 will offset part of the tension. When the conveyor belt tension decreases, the elastic force of the spring 12 pushes the slider 11 to slide downward, driving the tension adjustment wheel 4 to press down on the conveyor belt and increase the contact tension. Through the elastic deformation of the spring 12 and the sliding cooperation of the slider 11, the tension of the conveyor belt can be dynamically adjusted in real time to keep the tension stable within the set range.

[0031] Preferably, a damping sleeve 10 is installed inside the slider 11. The damping sleeve 10 is slidably installed on the outside of the guide rod 13. The function of the damping sleeve 10 is to provide a certain damping force during the sliding process of the slider 11, reduce the sliding speed of the slider 11, and prevent the slider 11 from causing violent shaking or vibration due to sudden external force. This helps to improve the stability and accuracy of tension adjustment, so that the tension of the conveyor belt can be adjusted more smoothly.

[0032] Preferably, the support adjustment mechanism 23 consists of a telescopic rod 8 and a pressure sensor 7. The pressure sensor 7 is installed on the upper side of the telescopic rod 8, which is installed at the front and rear ends on the left and right sides of the worktable 2. The pressure sensor 7 is installed at the front and rear ends on the left and right sides of the fixed frame 24. During use, the pressure sensor 7 monitors the pressure on the telescopic rod 8 in real time. When the pressure exceeds or falls below the set range, it sends a signal to the control system. The control system then adjusts the telescopic rod 8 to keep the pressure within a suitable range during the calendering process, ensuring the calendering effect and safe operation of the equipment. At the same time, the support adjustment mechanism 23 can make the fixed frame 24 bear force evenly, ensuring the stability of the calendering mechanism and further improving the quality of the conveyor belt forming.

[0033] Work steps

[0034] When the calendering device 1 is in use, the guide wheel 3 guides the raw material from the conveyor belt to smoothly enter the processing area, providing a stable feeding foundation for subsequent calendering processes. The tension adjustment mechanism 5 is crucial to ensuring uniform stress on the raw material. When tension fluctuations occur during the conveying process, the tension adjustment wheel 4 can adjust the tension of the raw material by adapting its own position and cooperating with relevant components, avoiding uneven tension that could lead to wrinkles or excessive stretching of the raw material, thus affecting the uniformity of the thickness after calendering. The fixed frame 24 serves as the mounting carrier for the upper calendering mechanism 6, and its surrounding support adjustment mechanism 23 can precisely control the position of the fixed frame 24. On the one hand, it ensures the relative position stability between the upper calendering mechanism 6 and the lower calendering mechanism 9, providing structural protection for the consistency of calendering thickness. On the other hand, when the raw material experiences local thickening or thinning, the support adjustment mechanism 23 can cooperate with the movement of the calendering mechanism to provide reliable support and adjustment space for adjusting the roller spacing, ensuring the stability of the entire calendering process. The distance measuring mechanism 15 monitors the relative distance between the fixed frame 24 and the worktable 2 in real time, providing data reference for the precise adjustment of the roller spacing.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
