Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber hose production, in particular to a raw material discharge and tensioning system for glass fiber hose production. Background Art

[0002] In the production of fiberglass hoses, the stability and tension control of raw material unloading are crucial. Traditional unloading systems often have many shortcomings and cannot meet the needs of high-quality production.

[0003] In the early days of fiberglass hose production, the raw material unwinding process often relied on simple mechanical structures for support and transmission, lacking precise tension adjustment devices. For example, relying solely on a conventional fixed shaft to position the coiled material prevented flexible adjustment of the raw material tension based on actual production needs. This resulted in the raw material becoming loose or overly tensile during the unwinding process. Loose material can easily lead to uneven winding, disrupting subsequent processing steps and even requiring production interruptions for re-reading. Excessive tension can damage the raw material's physical properties, such as breaking the glass fiber or damaging the internal structure, reducing the hose's quality and strength.

[0004] With technological advancements, some unwinding systems have begun to incorporate simple brake devices to control tension. However, these devices suffer from low control accuracy. They struggle to accurately set and dynamically adjust tension in real time, and they are unable to quickly respond to and appropriately adjust tension when faced with varying raw material coils and fluctuating production process parameters. For example, when switching between glass fiber coils of varying thicknesses or widths, traditional brakes can't adjust braking force in a timely manner, affecting unwinding stability and uniformity.

[0005] Furthermore, the support structure design of traditional unloading systems is not rational. It often lacks consideration for compatibility with coils of varying sizes, leading to issues such as awkward installation and inaccurate positioning. Furthermore, the lack of effective auxiliary structures can easily lead to system instability during long-term operation due to uneven weight distribution of the coils or vibration during rotation, impacting production efficiency and product quality.

[0006] Therefore, it is necessary to provide a raw material unloading and tensioning system for making a glass fiber hose to solve the above technical problems. Utility Model Content

[0007] In order to overcome the above problems, the utility model provides a raw material discharge and tensioning system for manufacturing a glass fiber hose.

[0008] The technical implementation scheme of the present utility model is a raw material discharge tensioning system for producing a glass fiber hose, including a tensioning device and a support frame. The tensioning device is arranged on the top of the support frame, and the tensioning device includes multiple magnetic powder brakes, a tension controller and an air shaft. The support frame includes multiple L-shaped horizontal support rods, horizontal support rods and vertical support rods. One end of the vertical support rods is connected by an L-shaped horizontal support rod, and the other end of the vertical support rods is connected by a horizontal support rod.

[0009] Preferably, the vertical support rods are symmetrically arranged on the left and right, with horizontal support rods fixedly connected between the vertical support rods on the left, and the length of the vertical rods of the horizontal support rods increasing by 20 cm from left to right, and L-shaped horizontal support rods fixedly connected between the side vertical support rods on the right, and the length of the sides of the L-shaped horizontal support rods parallel to the horizontal support rods increasing by 20 cm from front to back and the lengths of the four L-shaped horizontal support rods at the rear end remain consistent.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0025] See also Figures 1-6A tensioning system for raw material discharge of glass fiber hose production includes a tensioning device and a support frame. A tensioning device is provided on the top of the support frame. The tensioning device includes multiple magnetic powder brakes 4, a tension controller 8 and an air shaft 9. The support frame includes multiple L-shaped horizontal support rods 5, horizontal support rods 10 and vertical support rods 2. One end of the vertical support rods 2 is connected by the L-shaped horizontal support rod 5, and the other end of the vertical support rods 2 is connected by the horizontal support rod 10. The vertical support rods 2 are arranged symmetrically on the left and right. The horizontal support rods 10 are fixedly connected between the vertical support rods 2 on the left. The length of the vertical rods of the horizontal support rods 10 increases by 2 from left to right. 0 cm, an L-shaped horizontal support rod 5 is fixedly connected between the side vertical support rods 2 on the right side, and the length of the side of the L-shaped horizontal support rod 5 parallel to the horizontal support rod 10 increases by 20 cm from front to back, and the lengths of the four L-shaped horizontal support rods 5 at the rear end remain consistent; the horizontal support rod 10, the L-shaped horizontal support rod 5 and the middle position of the side parallel to the horizontal support rod 10 are fixedly connected with a safety chuck 7, and the horizontal support rod 10 and the L-shaped horizontal support rod 5 are rotatably connected with an inflatable shaft 9 through the safety chuck 7, and the safety chuck 7 away from the side of the horizontal support rod 10 is provided with a magnetic powder brake 4.

[0026] Among them, the length of the transverse rod of the L-shaped cross support rod 5 increases by 20 cm from left to right. During work, it can ensure that there is a certain distance of misalignment between the material rolls in the middle of each inflatable shaft 9, so that when the material rolls are pulled apart, the side edges of each layer of material have a fixed distance, which is convenient for the later overlap of each layer of material to make pipelines. This design reduces the labor intensity of workers and enhances work efficiency; and the inflatable shaft 9 plays the role of fixing the material roll in the middle of the inflatable shaft 9 when working, preventing the material roll from slipping during work and affecting the work quality; the inflatable shaft 9 is rotatably connected between the safety chuck 7 to facilitate the disassembly and installation of the inflatable shaft 9. During work, if the material roll in the middle of the inflatable shaft 9 is used up, the safety chuck 7 at one end of the inflatable shaft 9 can be opened to take out one end of the inflatable shaft 9 and replace the used material roll.

[0027] See also Figure 1 and Figure 3 The horizontal support rods 10 are fixedly connected with tension controllers 8 , and the tension controllers 8 are electrically connected to the magnetic powder brakes 4 .

[0028] The tension controller 8 can adjust the braking torque of the magnetic powder controller 4 at any time. As the braking torque of the magnetic powder controller 4 changes, the rotation speed of the pneumatic shaft 9 will be reduced, thereby ensuring that the material remains in a tensioned state after being pulled out, ensuring the overall stability and the tightness of the fit of each layer of material.

[0029] See also Figure 1-Figure 3The tops of the vertical support rods 2 are fixedly connected to bearing seats 3, and guide rollers 1 are rotatably connected between the bearing seats 3. The length of the guide rollers 1 increases from left to right; the bottoms of the vertical support rods 2 are fixedly connected to fixed bases 6.

[0030] When the guide roller 1 is working, the guide roller 1 can support the material of the material roll on the inflatable shaft 9 to continuously move forward and guide the movement of the material, while the fixed base 6 plays a role in stabilizing the device.

[0031] When working, first place the material roll in the middle of the inflatable shaft 9, then place the inflatable shaft 9 in the safety chuck 7, and lock the safety chuck 7 to limit the inflatable shaft 9, then re-inject compressed air into the inflatable shaft 9 to prop up the key strip in the inflatable shaft 9 until it is tightly fitted with the core of the material roll, and then pass the joint of the material roll from the guide roller 1 in front of the inflatable shaft 9 to the guide roller 1 at the far right end. After completing this step, adjust the tension controller 8. The tension controller 8 keeps the braking torque of the magnetic powder brake 4 at a certain value. During work, as the material roll continues to rotate, if the tension force at some positions is inappropriate, adjust the tension controller 8 at the corresponding position. When the material of the material roll is used up, release the gas in the inflatable shaft 9 until it is separated from the core of the material roll, then open the safety chuck 7 at both ends of the inflatable shaft 9, and take out the inflatable shaft 9 to replace the material roll. After the replacement is completed, repeat the installation steps to make it continue to work.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
