Description

Technical Field

[0001] This utility model relates to a binding strap tightener reel, which is particularly suitable for the coil tightening of webbing in applications. Background Technology

[0002] Currently, strapping tighteners are widely used in cargo packaging and transportation securing. Common strapping tighteners fall into two types: one is a ratchet tightener connected to the strapping, which serves two purposes: tightening and connecting the strapping; the other is a strapping strapping machine, used in conjunction with a connecting buckle. After the strapping machine tightens the strapping, the machine is removed, and the connecting buckle serves to connect the strapping.

[0003] The essential components of a strapping tightener include a spool, ratchet mechanism, handle, and main body. When the strapping tightener is used as a reusable packing machine, its components need to include a strap pressing mechanism and presser feet; to simplify the cutting process of excess strapping, a cutting device can be added. The function of the spool is to connect the strapping to the tightener and to shorten and tighten the strapping through its rotation. The main body of the spool is cylindrical, and the strapping coiling area of ​​the spool consists of two parallel clamping posts, spaced apart to form an elongated through hole, which serves as the strapping coiling hole. The spool achieves its function through the clamping posts and the strapping coiling hole. The strapping passes through the coiling hole, clamping the strapping body between the two clamping posts. The strapping bends at the coiling hole, connecting the strapping to the tightener; the rotation of the spool causes the strapping to be squeezed and wrapped around the clamping posts, thereby shortening and tightening the strapping body. There are two types of clamping columns: one type has two clamping columns connected at both ends, with the two ends of the coil hole formed by the two clamping columns being closed; the other type has two clamping columns connected at one end and not connected at the other end, with one end of the coil hole formed by the two clamping columns being closed and the other end being open.

[0004] When both ends of the tape reel hole are closed, the strap passes through the reel hole and is clamped between the two clamping posts. This is achieved by inserting the end of the strap into the reel hole and pulling it to ensure that the excess strap passes through the reel hole. When one end of the reel hole is closed and the other end is open, the strap passes through the reel hole and is clamped between the two clamping posts. This is achieved by directly inserting the main body of the strap horizontally into the reel hole at the open end; in this case, it is not necessary to pass the strap through the reel hole from the end.

[0005] Currently, ratchet tighteners connected to straps typically consist of two separate crescent-shaped bars on the spool. These bars serve as the main body of the spool and also act as clamping posts. The two crescent-shaped bars are spaced apart to form a coiling hole. Both ends of the crescent-shaped bars connect to the tightener body and the ratchet mechanism, while the coiling hole is closed at both ends. In use, the tightening end of the strap is passed through the coiling hole, clamping the strap body between the two crescent-shaped bars. The strap bends at the coiling hole, connecting the strap to the ratchet tightener. Turning the handle rotates the spool, causing the strap to be squeezed and wrapped around the clamping posts, thus shortening and tightening the strap body.

[0006] The ratchet tightener connected to the binding strap consists of a reel made of two crescent-shaped bars. Because both ends of the reel are connected to the tightener body and the ratchet mechanism, the two ends forming the coil hole are closed. When the binding strap is connected to the reel, the binding strap at the tightening end needs to pass through the coil hole from its end, which is cumbersome, especially when the excess binding strap at the tightening end is long, the amount of work involved in threading and pulling the strap is large, causing inconvenience to the operation.

[0007] Current strapping machines often require multiple straps to be used on the same machine. To facilitate the connection between the strap and the reel, the reel's coiling hole is designed with one end closed and the other open. This allows the strap to be inserted laterally into the open end of the coiling hole. The reel itself is a cylindrical, one-piece structure. One end of the cylinder is split in half to form a forked section, with the two forks serving as the strap clamping posts. The split slit forms the coiling hole, its width sufficient to allow the strap to pass through. The other end of the cylinder remains unsplit and connects to the machine body and ratchet mechanism. During use, when connecting the strap to the reel, it is not necessary to pass the strap through the coiling hole from its end. After straightening the tightened section of the strap, it is directly inserted laterally into the coiling hole from the open end, clamping the strap between the two clamping posts. This method simplifies the connection between the strap and the reel. Because the strapping needs to enter the coiling hole directly through the open end of the coiling hole, the main body of the coil at the open end of the coiling hole cannot be connected to the main body of the packing machine or the ratchet device, so as to avoid the open end being closed due to connection.

[0008] Currently, there are two types of coil holes on the reel of a strap tightener: one where both ends of the coil hole are closed, and the other where one end is closed and the other is open. The drawbacks of these two types are: when both ends of the coil hole are closed, both ends of the reel can be connected to the tightener body, which improves the stability of the reel under tension. However, with both ends of the coil hole closed, the strap must pass through the coil hole from its end when connecting to the reel, which is cumbersome, especially when the excess strap at the tightening end is long, resulting in a large workload for threading and pulling the strap. When one end of the coil hole is closed and the other is open, the strap does not need to pass through the coil hole from its end when connecting to the reel; the strap of the tightening section can be directly threaded through the hole. The strap is inserted horizontally into the hole from the open end of the strapping hole, which facilitates the connection between the strap and the reel. However, because one end of the strapping hole must remain open, the main body of the reel at the open end of the strapping hole cannot be connected to the main body of the tensioner. This means that only one end of the main body of the reel can be connected to the main body of the tensioner, which reduces the stability of the reel when subjected to tension. During the process of rotating and tightening the strapping, the reel is prone to breakage and deformation when the tightening tension is large. This structure is particularly problematic when dealing with heavy binding of large or heavy goods. Summary of the Invention

[0009] To overcome the shortcomings of existing tie-up strap tightener reels in application, this utility model provides a tie-up strap tightener reel. This tie-up strap tightener reel allows both ends of the reel to be connected to the tightener body, ensuring the stability of the reel under tension. Furthermore, when connecting the tie to the reel, it is not necessary to pass the tie through the coil hole at its end, thus simplifying the connection between the tie and the reel.

[0010] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides a binding strap tightening device reel. The main body of the reel is cylindrical. A long, narrow through-hole runs longitudinally through the middle region of the reel, with both ends closed. The long, narrow through-hole serves as the reel's winding hole. Two clamping posts of the reel are separated on either side of the winding hole. One clamping post has a break in its middle region, dividing it into two parts. The break is a dedicated entrance for the binding strap to enter the winding hole. In use, the connecting section between the binding strap and the reel is folded longitudinally, with the edges of the binding strap overlapping. The overlapping edges of the binding strap are then inserted horizontally into the break on the clamping post. During insertion, the overlapping edges of the binding strap are inserted first. After the binding strap is inserted horizontally into the break on the clamping post, the binding strap is pressed inwards and pulled to unfold it flat within the winding hole, thus achieving the connection between the binding strap and the reel.

[0011] To further explain, there is a fracture in the middle area of ​​one of the clamping columns. The fracture is the entrance for the strap to enter the coil hole. The outer width of the fracture needs to be greater than the total thickness of the strap after it is stacked to ensure that the stacked strap can enter the fracture smoothly. The fracture wall is V-shaped to increase the internal width of the fracture, thereby facilitating the strap to unfold flat in the coil hole.

[0012] To further explain, there is a coiling hole between the two clamping posts. The break in the middle area of ​​one of the clamping posts is a dedicated channel for the strap to enter the coiling hole. This channel is connected to the coiling hole. The fact that both ends of the coiling hole are closed does not affect the horizontal insertion of the strap into the coiling hole, thus ensuring that both ends of the reel can be connected to the main body of the tensioner.

[0013] To further explain, the strap passes through a break in the middle of a clamping post and enters the coiling hole. The main body of the strap is clamped between the two clamping posts. The strap bends at the coiling hole, connecting the strap to the tightener. The rotation of the reel causes the strap to be squeezed and wrapped around the clamping posts, thus shortening and tightening the main body of the strap. When the reel rotates to tighten the strap, the clamping posts bear the tensile force. One of the clamping posts has a break in the middle. There are two ways to improve the tensile strength of the clamping post with the break: one is to shift the longitudinal center line of the coiling hole towards the clamping post without the break, thereby increasing the cross-sectional area of ​​the clamping post with the break and thus improving its tensile strength; the other is to increase the width of the break in the middle of the clamping post, thereby shortening the suspended length of the clamping posts on both sides of the break and thus improving its tensile strength.

[0014] The beneficial effects of this utility model of a strap tightener reel are as follows: both ends of the reel's coil hole are closed, ensuring that both ends of the reel can be connected to the tightener body, thereby ensuring the stability of the reel when subjected to tension; at the same time, the reel has a dedicated channel for the strap to enter the coil hole, and the strap can be directly inserted into the coil hole laterally through the dedicated channel, without having to thread the strap through its end into the coil hole, thus facilitating the connection between the strap and the reel.

[0033] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the following preferred embodiments are provided, but the technical concept of this utility model is not limited to the following embodiments.

[0034] Example 1

[0035] This embodiment illustrates the application of the binding strap tightener reel of this utility model in a binding strap packaging machine.

[0036] Figure 1 , Figure 2 , Figure 3 , Figure 4 In the middle, the main body of the packing machine reel (1) is cylindrical. Figure 3 , Figure 4 In the middle section of the main body of the baling machine reel (1), there is a longitudinal through hole, which is a coiling hole. The longitudinal center line of the coiling hole is located below the longitudinal center line of the main body of the baling machine reel (1). The coiling hole divides the shaft into upper and lower parts, which are the clamping columns of the baling machine reel (1). The cross-sectional area of ​​the upper clamping column is larger than that of the lower clamping column. There is a fracture in the middle section of the upper clamping column. This fracture is the entrance for the strapping to enter the coiling hole. The outer width of the fracture is larger than the total thickness of the strapping after stacking, so as to ensure that the stacked strapping can smoothly enter the fracture. The fracture wall is V-shaped to increase the internal width of the fracture, thereby facilitating the strapping to unfold flat in the coiling hole. The fracture divides the upper clamping column into two sections, one end of which is suspended. The cross-sectional area of ​​the upper clamping column is larger than that of the lower clamping column, which is intended to increase the tensile strength of the upper clamping column.

[0037] Figure 5 , Figure 6 In this design, one end of the baling machine reel (1) is directly connected to the baling machine body (4) and the ratchet assembly (8), while the other end is connected to the shaft of the baling machine body (4) and the pressing mechanism (3) via a connector (6). Both ends of the baling machine reel (1) are connected to the baling machine body (4), which improves the stability of the baling machine reel (1) when it is under tension during the tape winding process.

[0038] Figure 7 In the middle, the strapping mechanism (3) of the strapping machine connects the strapping machine with the strapping strap (11). The folded end of the strapping strap (11) passes through the strapping cutting device (2). By turning the handle (7), the clamping column with the broken end on the strapping machine reel (1) is turned upward, and the strapping strap (11) adjacent to the clamping column is folded downward longitudinally. The two sides of the strapping strap (11) are overlapped together, and the overlapping edges of the strap body are inserted into the broken end on the clamping column first.

[0039] Figure 8 In the middle, the fracture wall on the clamping column is V-shaped, and the internal width of the fracture is greater than the entrance width. The edge of the stacked strip is inserted into the fracture first. By pressing the strip inward and pulling the excess binding strip (11), the binding strip (11) is spread out flat in the coil hole of the baling machine reel (1). The baling machine reel (1) is rotated by the handle (7) to squeeze and wrap the binding strip (11) around the outside of the shaft, thereby shortening and tightening the main body of the binding strip (11).

[0040] Example 2

[0041] This embodiment illustrates the application of the binding strap tightener reel of this utility model in a ratchet tightener.

[0042] Figure 9 , Figure 10 , Figure 11 , Figure 12 In the ratchet tightener reel (21), the main body is cylindrical. The middle section of the main body of the ratchet tightener reel (21) has a longitudinal through-hole, which serves as a strapping hole. This hole divides the shaft into upper and lower parts, which are the strapping posts of the ratchet tightener reel (21). The middle section of the upper strapping post has a fracture, which is the entrance for the strap into the strapping hole. The fracture wall is V-shaped to increase the internal width of the fracture, thus facilitating the strapping to unfold flat within the strapping hole. The fracture divides the upper strapping post into left and right sections, each with one end suspended. The fracture of the upper strapping post is widened overall to shorten the suspended length of the left and right sections, aiming to increase the tensile strength of the upper strapping post.

[0043] Figure 13 , Figure 14 In the middle, the two ends of the ratchet tensioner spool (21) are connected to the ratchet tensioner (22).

[0044] Figure 15 In the middle, by turning the handle of the ratchet tightener (22), the clamping post with the break on the ratchet tightener spool (21) is turned outward, and the folded-back binding strap (11) is folded downward longitudinally near the clamping post. The two sides of the binding strap (11) are overlapped together, and the overlapped edges of the strap body are first inserted into the break on the clamping post.

[0045] Figure 8 In the process, the fracture wall on the clamping post is V-shaped, and the internal width of the fracture is greater than the entrance width. The edges of the overlapping straps are first inserted into the fracture. By pressing the straps inward and pulling the excess binding strap (11), the binding strap (11) is spread out flat in the coil hole of the ratchet tightener spool (21). By driving the ratchet tightener spool (21) to rotate, the binding strap (11) is squeezed and wrapped around the outside of the spool, thereby shortening and tightening the main body of the binding strap (11).
