Description

Technical Field

[0001] This application relates to the technical field of ton bag production equipment, specifically a heating and stretching device. Background Technology

[0002] The general production process of ton bags involves injection molding to heat-melt and form a "fabric"-like roll, which is then cut into threads. These threads are woven into "fabric"-like rolls, cut into individual units, and then sewn together to form ton bags. During the initial cutting of the "fabric"-like material into threads, these threads undergo heat stretching treatment. This step significantly improves the physical properties of the threads, such as strength and toughness, ensuring that the final ton bags can withstand significant weight and possess good durability. Finally, after careful weaving, these unit blocks are assembled into complete ton bags, providing a reliable packaging solution for the storage and transportation of goods.

[0003] However, in the existing technology, it is found that the cut filaments need to be fed into a heating box for heating. Heating helps with ductility. Finally, they are stretched by multiple rollers. However, the distance between the upper and lower rollers is fixed, which means that the stretching force can only remain constant when stretching the filaments. When the diameter of the stretched filaments does not meet the requirements or is overstretched, it affects the product quality and easily leads to a reduction in the durability of the ton bags produced. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a heating and stretching device that can determine whether the stretching force is sufficient by detecting the diameter of the stretched material, thereby adjusting the distance between the lower and upper rollers, adjusting the stretching force, and improving product quality. This solves the problem in existing technologies where the distance between the upper and lower rollers used for stretching is fixed, resulting in the stretching force remaining constant. When the diameter of the stretched filament does not meet the requirements or the stretching is excessive, it affects product quality and easily leads to a reduction in the durability of the manufactured ton bags.

[0005] To achieve the above objectives, this application provides the following technical solution: a heating and stretching device, comprising a mounting rod, a laser diameter gauge fixedly mounted on the right side of the mounting rod, a fixed plate fixedly connected to the left side of the mounting rod, two upper rollers rotatably connected to the inner wall of the fixed plate, a motor fixedly mounted on the back of the fixed plate, a threaded rod fixedly connected to the output shaft of the motor, a threaded block threadedly connected to the outer surface of the threaded rod, a sliding plate fixedly connected to the front of the threaded block, two lower rollers rotatably connected to the inner wall of the sliding plate, two fixed blocks fixedly connected to the front of the sliding plate, a guide rod fixedly connected to the inner wall of each fixed block, and the outer surface of each guide rod slidably connected to the inner wall of the fixed plate.

[0006] The above scheme enables real-time detection of the stretched material to check if the diameter meets the standard, thereby adjusting the distance between the upper and lower rollers and adapting the appropriate tensile force to improve product quality. A laser diameter gauge is installed on the right side of mounting rod one. This gauge detects the diameter of the stretched material. When the diameter is below standard, motor one is activated, causing the threaded rod to rotate. This rotation raises and lowers the threaded block, which in turn raises and lowers the threaded block, sliding plate, lower roller, and fixed block. The fixed block drives the guide rod, which connects to the fixed plate, limiting the movement of the sliding plate and adjusting the height of the lower roller. This allows the device to detect the diameter of the stretched material in real-time, ensuring the tensile force is sufficient, and adjusting the distance between the upper and lower rollers to regulate the tensile force. This ensures the material is subjected to the appropriate tensile force, improving product quality.

[0007] Furthermore, an mounting plate is fixedly installed at the bottom end of the mounting rod, and the upper surface of the mounting plate is rotatably connected to the bottom end of the threaded rod.

[0008] The above scheme connects the mounting plate to the bottom of the mounting rod, providing support for the mounting rod. The bottom of the threaded rod is connected to the upper surface of the mounting plate, forming a rotatable connection to limit the movement of the threaded rod and ensure its stable rotation.

[0009] Furthermore, a second mounting rod is fixedly mounted on the upper surface of the mounting plate, and the right side of the second mounting rod is fixedly connected to the left side of the fixed plate.

[0010] The above method involves installing the second mounting rod on the upper surface of the mounting plate and fixing it in place. This allows for the installation of the second mounting rod, and the right side of the second mounting rod is fixed to the fixed plate, thus supporting and installing the fixed plate.

[0011] Furthermore, a second motor is fixedly installed on the back of the fixed plate, and the output shaft of the second motor is fixedly connected to the end of the corresponding upper roller.

[0012] The above method connects motor 2 to the fixed plate and motor 2 to the corresponding upper roller. Motor 2 enables the corresponding upper roller to rotate and pull the material.

[0013] Furthermore, a mounting frame is provided on the left side of the mounting plate, and a lower housing is fixedly connected to the upper surface of the mounting frame.

[0014] The above method involves placing the mounting frame on the left side of the mounting plate and fixing the lower housing to the mounting frame, thereby achieving support and installation of the lower housing.

[0015] Furthermore, an upper shell is fixedly installed on the upper surface of the lower shell, and conveying rollers arranged at equal intervals are rotatably connected to the inner wall of the upper shell.

[0016] The above scheme involves installing the upper housing on the upper surface of the lower housing and fixing it with bolts to achieve the installation of the upper housing. The conveying roller is installed on the inner wall of the upper housing and set as a rotatable connection to achieve the limiting of the conveying roller and facilitate the transfer of materials through the conveying roller.

[0017] Furthermore, a heating wire is fixedly installed on the inner wall of the upper housing, and two temperature sensors are fixedly installed on the inner side wall of the upper housing.

[0018] The above scheme involves installing a heating wire on the inner wall of the upper housing. Through the heating wire and external heating components, the heating wire can heat the inside of the upper housing, thereby heating the material on the surface of the conveyor roller. Temperature sensors are installed on the inner wall of the upper housing, with one on each of the left and right sides, to monitor the temperature inside the upper housing in real time and prevent the temperature from being too high or too low.

[0019] Furthermore, a controller is fixedly mounted on the front of the upper housing, and the controller is electrically connected to the temperature sensor.

[0020] With the above solution, the controller is installed on the front of the upper housing, and the temperature sensor is connected to the controller via an electrical signal. When the temperature sensor detects that the temperature is below or above the standard, it transmits the signal to the controller, which then controls the start and stop of the heating wire.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This heating and stretching device incorporates components such as a laser diameter gauge, a threaded rod, a lower roller, and a guide rod. The laser diameter gauge detects the diameter of the stretched material. If the diameter is below standard, the motor is activated, causing the threaded rod to rotate. This, in turn, raises and lowers the threaded block. Simultaneously, the threaded block, sliding plate, lower roller, and fixed block move together. The guide rod, connected to the fixed plate, limits the sliding plate's movement, allowing for height adjustment of the lower roller. This enables the device to determine if the stretching force is sufficient by detecting the diameter of the stretched material, and then adjust the distance between the lower and upper rollers to regulate the stretching force, ensuring the material is suited to the appropriate stretching force and improving product quality. A temperature sensor monitors the internal temperature of the upper casing in real time. When the temperature is below or above standard, an electrical signal is transmitted to the controller, which then starts and stops the heating wire, preventing the material from being heated too high or too low.

The mounting frame 15 is set on the left side of the mounting plate 12, and the lower housing 16 is fixed to the mounting frame 15 to achieve support and installation of the lower housing 16.

[0036] Please see Figure 1 , Figure 2 and Figure 5 An upper housing 17 is fixedly installed on the upper surface of the lower housing 16. Conveying rollers 18 arranged at equal intervals are rotatably connected to the inner wall of the upper housing 17.

[0037] Please see Figure 1 and Figure 5A heating wire 19 is fixedly installed on the inner wall of the upper housing 17. Two temperature sensors 20 are fixedly installed on the inner side wall of the upper housing 17. By installing the heating wire 19 on the inner wall of the upper housing 17 and the external heating components, the heating wire 19 can heat the inside of the upper housing 17, thereby heating the material on the surface of the conveying roller 18. The temperature sensors 20 are installed on the inner side wall of the upper housing 17, with one on each of the left and right sides of the upper housing 17, so that the temperature inside the upper housing 17 can be detected in real time to prevent the temperature from being too high or too low.

[0038] Please see Figure 1 , Figure 2 and Figure 5 A controller 21 is fixedly installed on the front of the upper housing 17. The controller 21 is electrically connected to the temperature sensor 20. The controller 21 is installed on the front of the upper housing 17, and the temperature sensor 20 is connected to the controller 21 through an electrical signal. When the temperature sensor 20 detects that the temperature is not up to standard or the temperature is over standard, it transmits the signal to the controller 21, and then the controller 21 controls the start and stop of the heating wire 19.

[0039] This embodiment of a heating and stretching device includes components such as a laser diameter gauge 2, a threaded rod 6, a lower roller 8, and a guide rod 10. The laser diameter gauge 2 detects the diameter of the stretched material. If the diameter is below standard, the motor 5 is started to rotate the threaded rod 6, which in turn raises and lowers the threaded block 7. At this time, the threaded block 7, the sliding plate 11, the lower roller 8, and the fixed block 9 rise and fall together. The guide rod 10 is connected to the fixed plate 3 to limit the sliding plate 11, thereby adjusting the height of the lower roller 8. This allows the device to determine whether the stretching force is sufficient by detecting the diameter of the stretched material, and then adjust the distance between the lower roller 8 and the upper roller 4 to adjust the stretching force, so that the material can be adapted to the appropriate stretching force, thus improving product quality. A temperature sensor 20 is installed to detect the temperature inside the upper housing 17 in real time. When the temperature is below or above standard, an electrical signal is transmitted to the controller 21, which controls the start and stop of the heating wire 19, preventing the material from being heated too high or too low.

[0040] It should be noted that both motor 5 and motor 14 are servo motors. Motor 5 controls the forward and reverse rotation of the threaded rod 6 to control the height of the lower roller 8. Motor 14 controls the rotation of one of the upper rollers 4 to adjust the speed of the upper roller 4. After the thread is stretched by the upper roller 4 and the lower roller 8, the diameter of the thread can be detected by the laser diameter measuring instrument 2 to determine whether the stretched thread meets the standard.

[0041] The working principle of the above embodiments is as follows:

[0042] Heating is achieved through heating wire 19, allowing the material inside the upper housing 17 to be heated. Temperature sensor 20 monitors the temperature in real time. When the temperature is below or above the standard, an electrical signal is transmitted to controller 21, which then starts and stops the heating wire 19 to prevent the material from being heated too high or too low. Motor 21 rotates the upper roller 4, facilitating the pulling of the heated material. The heated material is stretched through the winding path between the upper roller 4 and the lower roller 8. The diameter of the stretched material is then detected by laser diameter measuring instrument 2. If the diameter is below the standard, motor 15 is started to rotate the threaded rod 6, which in turn raises and lowers the threaded block 7. At this time, the threaded block 7, sliding plate 11, lower roller 8, and fixed block 9 rise and fall together. The guide rod 10 is connected to the fixed plate 3 to limit the sliding plate 11, thereby adjusting the height of the lower roller 8. This allows the device to determine whether the stretching force is sufficient by detecting the diameter of the stretched material, and then adjust the distance between the lower roller 8 and the upper roller 4 to adjust the stretching force, ensuring that the material is subjected to the appropriate stretching force and improving product quality.
