Description

Technical Field

[0001] This application relates to the field of mechanical manufacturing and bonding equipment technology, and in particular to a movable hand-expanding shaft. Background Technology

[0002] In traditional lamination equipment, tension adjustment belts or rollers are typically added to regulate product tension during the lamination process for smooth operation. This method requires additional structural elements, increasing the overall complexity of the equipment and making design, manufacturing, installation, and commissioning more cumbersome. The extra components also raise production costs. Furthermore, tension belts and rollers are prone to wear and aging due to frequent operation, requiring regular inspection, maintenance, and replacement. This undoubtedly increases operating costs and downtime, negatively impacting production efficiency. Furthermore, traditional hand-operated expansion shafts have structural limitations; their connection to the equipment is relatively fixed, and they cannot flexibly adjust their position according to the tension requirements of the unwound product. When it is necessary to adjust the tension of the unwound product, one can only rely on the aforementioned additional tension adjusting belt or tension adjusting roller, which makes it difficult to achieve convenient, efficient, and precise tension adjustment. Therefore, a movable hand-operated expansion shaft is provided. Utility Model Content

[0003] The purpose of this application is to provide a movable hand-expanding shaft that eliminates the need for traditional tension adjustment belts or rollers, simplifies the equipment structure, reduces costs, and avoids maintenance problems caused by wear of additional parts, enabling the laminating machine to adjust tension even without a traditional tension adjustment structure.

[0004] The movable hand-operated expansion shaft provided in this application adopts the following technical solution: it includes a hand-operated expansion shaft body and a worktable. The hand-operated expansion shaft body is disposed on the front side of the worktable. A T-shaped track is provided on the front side of the worktable. Two sets of T-shaped tracks are provided and symmetrically arranged on the front side of the worktable. A mounting base is fixedly connected to the rear end of the hand-operated expansion shaft body. Fixing blocks are fixedly connected to the upper and lower sides of the mounting base near the T-shaped track. Both sets of fixing blocks have through holes. Screws pass through the through holes. The head of the screw is a T-shaped structure adapted to the T-shaped track. The screw shaft passes through the through hole inside the fixing block and is fastened by a nut. By adopting the above technical solution, and by setting up a hand-operated expansion shaft body, a worktable, a T-shaped track, a mounting base, a fixing block, through holes, and screws, the hand-operated expansion shaft body is connected to the worktable via the mounting base. The through holes on the fixing block allow the screws to pass through, and the T-shaped heads of the screws are adapted to the T-shaped track. The screw rod is secured with a nut. This structure allows the hand-operated expansion shaft body to move along the T-shaped track to adjust the tension, eliminating the need for traditional tension adjusting belts or rollers, simplifying the equipment structure, reducing costs, and facilitating installation and disassembly, thus improving equipment flexibility.

[0005] Preferably, a roller is provided on the rear side of the mounting base, and the roller makes rolling contact with the surface of the worktable.

[0006] By adopting the above technical solution, the rollers on the rear side of the mounting base roll into contact with the worktable surface. When the hand-expanding shaft body drives the mounting base to move, the rollers can reduce friction, making the movement smoother and less strenuous, facilitating operators to quickly adjust the position of the hand-expanding shaft, and improving adjustment efficiency.

[0007] Preferably, limit blocks are provided at both ends of the two sets of T-shaped tracks, and the limit blocks are used to limit the range of movement of the mounting base on the T-shaped tracks.

[0008] By adopting the above technical solution, the limiting blocks at the left and right ends of the two sets of T-shaped tracks can block the mounting base when it moves to the extreme position, limit the range of movement of the mounting base, prevent it from leaving the T-shaped track, ensure the safe operation of the equipment, and avoid failures or production accidents caused by leaving the track.

[0009] Preferably, the hand-expanding shaft body is made of alloy steel.

[0010] By adopting the above technical solution, the hand-expanding shaft body is made of alloy steel. Alloy steel has high strength and good wear resistance, which enables the hand-expanding shaft body to withstand greater tension and pressure when carrying products for unwinding, making it less prone to deformation and damage, extending its service life, and ensuring long-term stable operation.

[0011] Preferably, the workbench is made of cast iron.

[0012] By adopting the above technical solution, the workbench is made of cast iron. Cast iron has good rigidity and strong stability. As a support base, it can stably support the hand-expanding shaft body, mounting base and other components. It is not easy to shake or deform during equipment operation, and provides reliable support for the stable movement and tension adjustment of the hand-expanding shaft.

[0013] Preferably, the roller is made of rubber.

[0014] By adopting the above technical solution, the rollers are made of rubber. Rubber is elastic and wear-resistant, which can reduce the noise when the rollers come into contact with the worktable, avoid scratching the worktable surface, and the elasticity can alleviate the vibration during movement, making the movement more stable.

[0015] Preferably, the limiting block is made of stainless steel.

[0016] By adopting the above technical solution, the limit block is made of stainless steel. Stainless steel is corrosion-resistant, has high strength, can withstand the impact force of the mounting base, and is not easy to rust or be damaged during long-term use, ensuring the long-term effectiveness of the limit function and extending its service life.

[0017] Preferably, the fixing block is made of carbon structural steel.

[0018] By adopting the above technical solution, the fixing block is made of carbon structural steel. Carbon structural steel has good strength and toughness, which can stably connect the mounting base and screws, withstand the force when the hand expansion shaft moves, and is not easy to break or deform, thus ensuring structural stability and ensuring the normal movement and fixation of the hand expansion shaft.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This movable hand-operated tension shaft comprises a T-shaped track, screws, a mounting base, and a fixing block. The T-shaped track is symmetrically arranged on the front side of the worktable. The fixing block is fixed to one end of the mounting base near the T-shaped track. The screws pass through the through holes of the fixing block, with their T-shaped heads embedded in the T-shaped track. The screw portion is secured by a nut. When tension adjustment is required, the nut is loosened, pushing the hand-operated tension shaft body. The mounting base then moves the screws along the T-shaped track, thereby moving the hand-operated tension shaft body. This eliminates the need for traditional tension adjustment belts or rollers, simplifying the equipment structure, reducing costs, and avoiding maintenance issues caused by wear of additional components. It enables tension adjustment in the bonding machine without a traditional tension adjustment structure.

[0020] 2. This movable hand-operated expansion shaft features rollers located on the rear side of the mounting base, making rolling contact with the worktable surface. As the hand-operated expansion shaft moves along the T-shaped tracks, the rollers roll accordingly, reducing friction between the mounting base and the worktable. This makes the movement of the hand-operated expansion shaft smoother and less strenuous, facilitating quick position adjustments by the operator and improving efficiency. Limit blocks are located at both ends of the two sets of T-shaped tracks. When the mounting base moves the hand-operated expansion shaft to its extreme position along the T-shaped tracks, the limit blocks prevent further movement, preventing the mounting base from detaching from the T-shaped tracks, avoiding equipment damage or production disruptions, and ensuring operational safety.

[0021] 3. This movable hand-operated expansion shaft features an alloy steel body, which boasts high strength and wear resistance. During product unwinding, the shaft can withstand significant tension and pressure, resisting deformation or damage and extending its service life to ensure long-term stable operation. The worktable, made of cast iron, offers excellent rigidity and stability. As a support base, it firmly supports the shaft body, mounting base, and other components, preventing shaking or deformation during operation and providing reliable support for stable movement and tension adjustment. The rollers, made of rubber, offer elasticity and wear resistance. Their contact with the worktable reduces friction noise and prevents scratches on the worktable surface. Furthermore, the rubber's elasticity alleviates minor vibrations during movement, resulting in smoother motion. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A movable hand-operated expansion shaft, see reference. Figure 1 , Figure 2 and Figure 4The device includes a hand-operated shaft body 1 and a worktable 2. The hand-operated shaft body 1 is located on the front side of the worktable 2. A T-shaped rail 3 is provided on the front side of the worktable 2. Two sets of T-shaped rails 3 are provided and symmetrically arranged on the front side of the worktable 2. A mounting base 4 is fixedly connected to the rear end of the hand-operated shaft body 1. Fixing blocks 5 are fixedly connected to the upper and lower sides of the end of the mounting base 4 near the T-shaped rail 3. Both sets of fixing blocks 5 have through holes 6 inside. Screws 7 pass through the through holes 6. The head of the screw 7 is a T-shaped structure that matches the T-shaped rail 3. The screw part of the screw 7 passes through the through hole 6 inside the fixing block 5 and is fastened with a nut. By setting up the hand-operated shaft body 1, the worktable 2, the T-shaped rail 3, the mounting base 4, the fixing blocks 5, the through holes 6, and the screws 7, the hand-operated shaft body 1 is connected to the worktable 2 through the mounting base 4. The through holes 6 on the fixing blocks 5 allow the screws 7 to pass through. The T-shaped head of the screw 7 matches the T-shaped rail 3, and the screw part is fastened with a nut. This structure allows the hand-operated expansion shaft body 1 to move along the T-shaped track 3 to adjust the tension, eliminating the need for traditional tension adjustment belts or rollers, simplifying the equipment structure, reducing costs, and facilitating installation and disassembly, thus improving equipment flexibility.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The mounting base 4 is equipped with rollers 8 on its rear side, which roll in contact with the surface of the worktable 2. Limiting blocks 9 are provided at both ends of the two sets of T-shaped rails 3. The limiting blocks 9 are used to limit the range of movement of the mounting base 4 on the T-shaped rails 3. The rollers 8 on the rear side of the mounting base 4 roll in contact with the surface of the worktable 2. When the hand-operated shaft body 1 drives the mounting base 4 to move, the rollers 8 can reduce friction, making the movement smoother and less strenuous, and making it easier for operators to quickly adjust the position of the hand-operated shaft, thus improving adjustment efficiency. The limiting blocks 9 at both ends of the two sets of T-shaped rails 3 can act as a stop when the mounting base 4 moves to the extreme position, limiting the range of movement of the mounting base 4, preventing it from falling off the T-shaped rails 3, ensuring the safe operation of the equipment, and avoiding malfunctions or production accidents caused by falling off.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The hand-operated shaft body 1 is made of alloy steel, and the worktable 2 is made of cast iron. The high strength and wear resistance of alloy steel allow the hand-operated shaft body 1 to withstand greater tension and pressure when unwinding products, making it less prone to deformation and damage, extending its service life, and ensuring long-term stable operation. The worktable 2 is made of cast iron, which has good rigidity and stability. As a support base, it can stably support the hand-operated shaft body 1, mounting base 4, and other components, making it less prone to shaking and deformation during equipment operation, and providing reliable support for the stable movement and tension adjustment of the hand-operated shaft.

[0028] Reference Figure 1 , Figure 2 and Figure 5 The roller 8 is made of rubber, the limit block 9 is made of stainless steel, and the fixing block 5 is made of carbon structural steel. The rubber material of the roller 8 is elastic and wear-resistant, which can reduce the noise when the roller 8 contacts the worktable 2, prevent scratching the surface of the worktable 2, and the elasticity can alleviate the vibration during movement, making the movement more stable. The stainless steel material of the limit block 9 is corrosion-resistant and high-strength, which can withstand the impact force of the mounting base 4. It is not easy to rust or be damaged in the long term, ensuring the long-term effectiveness of the limit function and extending its service life. The carbon structural steel material of the fixing block 5 is strong and tough, which can firmly connect the mounting base 4 and the screw 7, withstand the force when the hand expansion shaft moves, is not easy to break or deform, ensures structural stability, and ensures the normal movement and fixation of the hand expansion shaft.

[0029] In this embodiment, the movable hand-operated tension shaft is constructed using a T-shaped track 3, screws 7, a mounting base 4, and a fixing block 5. The T-shaped track 3 is symmetrically arranged on the front side of the worktable 2. The fixing block 5 is fixed to one end of the mounting base 4 near the T-shaped track 3. The screws 7 pass through the through hole 6 of the fixing block 5, with their T-shaped heads embedded in the T-shaped track 3. The screw portion is secured by a nut. When tension adjustment is required, the nut is loosened, pushing the hand-operated tension shaft body 1. The mounting base 4 then moves the screws 7 along the T-shaped track 3, thereby moving the hand-operated tension shaft body 1. This eliminates the need for traditional tension adjustment belts or rollers, simplifying the equipment structure, reducing costs, and avoiding maintenance issues caused by wear of additional components. It enables tension adjustment in the bonding machine without a traditional tension adjustment structure.

[0030] The implementation principle of this application embodiment is as follows: When it is necessary to adjust the tension of the unwound product, first loosen the nut of the screw 7 screw rod. At this time, the T-shaped head of the screw 7 is still embedded in the T-shaped track 3, but the mounting base 4 is no longer completely fixed. Push the hand-expanding shaft body 1. Since the rear end of the hand-expanding shaft body 1 is fixedly connected to the mounting base 4, the mounting base 4 will move accordingly, thereby driving the fixing blocks 5 fixed on its upper and lower sides to move. When the fixing blocks 5 move, the screw 7 passing through its internal through hole 6 will move along the length direction of the T-shaped track 3 along with the fixing blocks 5, thereby realizing the movement of the hand-expanding shaft body 1 along the T-shaped track 3. During the process of the hand-expanding shaft body 1 driving the mounting base 4 to move, the roller 8 on the rear side of the mounting base 4 rolls in contact with the surface of the worktable 2, reducing the frictional resistance between the mounting base 4 and the worktable 2, making the movement smoother. When the hand-expanding shaft body 1 moves away from the unwound device, the unwinding... As the tension on the product increases, the tension also increases. When the hand-operated expansion shaft body 1 moves closer to the unwinding device, the tension on the unwound product decreases, and the tension decreases accordingly, thus adjusting the tension of the unwound product. When the mounting base 4 moves to the end of the T-rail 3, the limiting blocks 9 at both ends of the T-rail 3 will prevent the mounting base 4 from moving further, preventing the mounting base 4 from detaching from the T-rail 3. After the tension adjustment is completed, tighten the nut on the screw 7, so that the screw 7 secures the fixing block 5 and the mounting base 4 in the current position, thereby fixing the position of the hand-operated expansion shaft body 1 and ensuring the stability of the tension during the unwinding process. During the process of the hand-operated expansion shaft body 1 bearing the product, because it is made of alloy steel, the fixing block 5 is made of carbon structural steel, and the worktable 2 is made of cast iron, the characteristics of these materials ensure the stability and reliability of each component under stress, ensuring that the entire equipment can work normally.
