Description

Technical Field

[0001] This invention relates to the field of binding devices, and more particularly to a binding device fixing fixture and fixing method. Background Technology

[0002] Driven by the rapid development of the logistics industry, the demand for related auxiliary technology fields is increasing. As a core component for securing large cargo, the production process of strapping devices needs to be efficient and uniform. In the production process of strapping devices, the combination and sewing between the strapping machine and the strapping strap is prone to errors. In order to ensure that the sewing area of ​​each strapping strap is uniform, the strapping machine and the strapping strap are usually placed on a tooling pallet to limit the position and improve the accuracy and uniformity of the sewing machine.

[0003] For example, publication number "CN217649847U" discloses "a strapping tray," which includes a tray body with several elastic clamps for fixing strapping devices and several positioning clamps for fixing strapping. Additionally, the tray body has several positioning seats for positioning hooks, located between the elastic clamps and the positioning clamps. Each positioning seat has a sewn opening between itself and the elastic clamps / positioning clamps for strapping insertion. However, in practical applications, due to the tray's cyclical use on the production line, the strapping and elastic clamps are frequently fastened and disassembled. The elastic clamps have a short lifespan, and the operation of fastening the strapping is laborious for workers. Furthermore, the edges of the strapping are prone to warping during fastening, and there is no fixed constraint in the strapping's extension direction. Summary of the Invention

[0004] In view of the problems mentioned in the background art, such as repeated disassembly and assembly affecting service life, laborious installation, easy warping of edges, and limited constraint range, the present invention provides a fixing fixture for a binding device, which can limit the binding strap in multiple directions through fixing teeth, so as to prevent the binding strap from being pulled back and displaced along the extension direction during subsequent conveying. At the same time, the binding strap is quick to install and does not change the overall shape of the binding strap. The fixing fixture has fewer moving parts and a longer service life.

[0005] The second objective of this invention is to protect the operational safety of workers, standardize operating procedures and operating areas, and improve the quality control of the binding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] A fixing fixture for a binding device includes a fixture base plate, on which a binding device assembly is disposed. The binding device assembly includes a binding main unit and binding straps. A sewing area is disposed on the fixture base plate, and the binding straps include an upper sewing piece and a lower sewing piece. A fixing bar is disposed next to the sewing area. When the binding device assembly is fixed to the fixture base plate, the fixing bar simultaneously penetrates the upper sewing piece and the lower sewing piece. Fixing spikes are installed on the tooling base plate. After the binding host is fixed, the binding strap is pressed into the fixing spikes, so that the area to be sewn on the binding strap corresponds to the sewing area. Since the binding strap is made by weaving and winding threads during the production process, the fixing spikes can pierce the binding strap through the gaps between the threads. The fixing operation is simple and quick, and does not damage the binding strap. The shape of the binding strap fixed on the tooling base plate will not change, ensuring that the surface of the binding strap is flat. After the fixing spikes pierce the binding strap, the binding strap is constrained in all directions except the vertical direction of the tooling base plate. When the sewing piece is also pierced by the fixing spikes, the binding strap will not be pulled back or displaced, ensuring the stable positioning of the binding strap. At the same time, the fixing spikes will not move or deform during the fixing process. Therefore, the fixing spikes have a long service life and can adapt to the production line process of frequent disassembly and assembly.

[0008] Preferably, slide rails are provided on both sides of the sewing area, and pressure sliders are detachably connected to the slide rails. The slide rails provide lateral positioning for the binding strap, ensuring its straightness and preventing misalignment. The slide rails also have slide rails, on which pressure sliders are detachably connected. The slide rails have slider mounting openings, and the pressure sliders have slide rail grooves. By aligning the slide rail grooves with the slide rails through the slider mounting openings, the pressure sliders are slid into the slide rails. Sliding the pressure sliders back and forth presses down on the surface of the binding strap, ensuring its flatness and uniform insertion depth relative to the fixing spikes at all points on the binding strap.

[0009] Preferably, the fixing spikes include spaced-apart piercings and short spikes. The thickness of the lower sewing piece is H1, the thickness of the upper sewing piece is H2, the thickness of the piercings is h1, and the thickness of the short spikes is h2, where h2 < H1 < h1 < H1 + H2. The fixing spikes include piercings and short spikes. The piercings can pierce the lower sewing piece and simultaneously penetrate the upper sewing piece, but not the upper sewing piece. The short spikes only penetrate the lower sewing piece without piercing it. When installing the fixing straps, the lower sewing piece is first fixed to the tool base plate. Because the short spikes and piercings are spaced apart, during fixing, after the piercings pass through the lower sewing piece, the worker can press the area between the two piercings with their fingers. Due to the impenetrability of the short spikes, the lower sewing piece is securely fixed, while protecting the worker. The fingers will not be pricked. Then, the binding strap is passed through the hook lock inside the binding host and then wrapped back to the sewing area. The upper sewing piece is fixed by piercing. Since the lower sewing piece will be subjected to more tensile force during installation, the short barbs and piercing are arranged alternately to ensure that the lower sewing piece is stabilized by enough fixing barbs while reducing the number of piercing holes formed by the lower sewing piece. At the same time, when the upper sewing piece is pulled back to fix it, the short barbs distribute the tensile force of the piercing and avoid excessive deformation and displacement due to the high piercing height.

[0010] Preferably, slide rails are provided on both sides of the sewing area, and pressure sliders are detachably connected to the slide rails. Several pressure protrusions are provided on the side of the pressure slider near the tool base plate, and clearance grooves are provided between adjacent pressure protrusions. The pressure protrusions correspond to short thorns, and the clearance grooves correspond to punctures. When the fixing bar has short barbs and piercing points, the pressure slider has corresponding pressure protrusions and clearance grooves. When the sewing lower piece is flattened and pressurized by the pressure slider, the pressure protrusion corresponds to the short barb area, and the clearance groove corresponds to the piercing area. The pressure protrusion simulates the manual pressing of the worker, improving the efficiency of fixing the binding strap. At the same time, since the distance between the slide rails is uniform, when the pressure slider is installed on the slide rail, the pressure protrusion corresponds to the short barb area. Therefore, there is no need to press the binding strap initially to expose the piercing points, which simplifies the fixing and installation steps of the sewing lower piece. After the sewing lower piece is fixed, the pressure slider can be removed from the slider installation port to install the sewing upper piece. Since the slider installation port is a notch set on the slide rail, the sewing needle moves horizontally through the slider installation port during the sewing process, realizing the sewing connection of multiple sewing straps on the tool base plate.

[0011] Preferably, the slide rail is an arc-shaped spring piece. When the binding strap is fixed on the sewing area, the arc-shaped spring piece abuts against both sides of the binding strap, and simultaneously abuts against the edge of the upper sewing piece away from the lower sewing piece. By setting the slide rail in the shape of an arc-shaped spring piece, when the binding strap is placed between the slide rails, the slide rails can provide vertical limiting constraints on the binding strap.

[0012] Preferably, the pressure slider can be mounted on the slide rail plate in both directions and slide relative to it. The pressure slider includes a lower pressure surface and an upper pressure surface. The thickness of the lower sewing piece is H1, and the thickness of the upper sewing piece is H2. When the lower pressure surface is positioned close to the tooling base plate, the distance between it and the tooling base plate is A1, and when the upper pressure surface is positioned close to the tooling base plate, the distance between it and the tooling base plate is A2, where A1=H1 and A2=H2+H1. The lower and upper pressure surfaces are provided on the front and back of the pressure slider, and the pressure slider can be mounted on the slide rail plate in both directions and slide relative to it. By mounting the pressure slider in both directions, the upper or lower sewing piece can be fixed and pressurized respectively, improving the fixing efficiency and protecting the labor intensity of the workers. Furthermore, the pressure slider includes a sliding block and a pressure block. The sliding block is detachably connected to the slide rail plate, and the pressure block is rotatably connected to the sliding block.

[0013] Preferably, the tooling base plate is provided with several main clamps, each with an inclined backing plate. The binding host is provided with a crank handle, and the inclined backing plate abuts against the crank handle. There is an angle difference α between the inclined backing plates on adjacent main clamps. During the fixing process of the binding host, the crank handle needs to be opened to avoid interfering with the worker's fixing of the binding strap. It also facilitates the subsequent gripping of the sewn binding device by the robotic arm. The inclined backing plate can limit the opening angle of the crank handle, ensuring a uniform opening angle. At the same time, setting different inclination angles for adjacent inclined backing plates creates an angle between adjacent crank handles, preventing insufficient placement space due to the width of the crank handle, and preventing the adjacent crank handles from pressing against the worker's hand due to being too close during the opening process, thus protecting operational safety.

[0014] Preferably, a method for securing a strapping device includes the following steps:

[0015] S1. Fix the main unit to the tool base plate and align the sewing piece with the sewing area;

[0016] S2. Press the sewing piece into the fixed thorn. The pressing position on the sewing piece corresponds to the top of the short thorn. The short thorn pierces into the sewing piece, penetrates through the sewing piece, and then pierces out.

[0017] S3. After passing the sewing piece through the binding machine, align it with the sewing area;

[0018] S4. Press the upper sewing piece into the fixing thorn. The pressing position on the upper sewing piece is the entire upper surface of the upper sewing piece, and the thorn is inserted into the upper sewing piece. After fixing the binding host on the tool base plate, pull the lower sewing piece flat and align it with the sewing area. Press down on the lower sewing piece so that the thorn passes through the lower sewing piece. At this time, press the area between the two thorns with your fingers to press the lower sewing piece a second time, so that the lower sewing piece is completely penetrated by the thorn and the short thorn enters into the lower sewing piece. After the lower sewing piece is fixed, pass the binding strap through the hook lock and fix the hook lock to the tool base plate. Then pull back the upper sewing piece to fix it through the thorn. During the sewing process, when the sewing needle starts to sew the first stitch, the upper sewing piece and the lower sewing piece can be fixedly connected. Therefore, during the sewing process, only one side of the upper sewing piece or the lower sewing piece needs to be stably fixed by the fixing thorn to maintain the overall fixation. This method can ensure that... The method of fixing the number of punctures effectively avoids excessive punctures that could create too many holes in the sewing lower piece. Simultaneously, due to the slender shape of the punctures and the small size and deformation of the short punctures, the punctures are prevented from breaking during the retraction of the sewing upper piece. After passing through the sewing lower piece, the punctures are fixedly connected to the sewing upper piece, thus constraining it and preventing misalignment between the sewing upper and lower pieces when they are transported to the sewing machine area after installation. Furthermore, this method ensures that the pressing area is fixed between the two punctures when pressing the sewing lower piece, avoiding the risk of operator injury from punctures. It also unifies the pressing actions and areas of each worker, improving the uniformity of the binding strap installation. This solution achieves the second objective of the invention.

[0019] Preferably, in step S2, the pressure slider is connected to the slide rail and slides along the slide rail, with the pressure protrusion abutting against the upper surface of the sewing piece corresponding to the short thorn. During the worker's process of fixing and pressurizing the sewing piece, the pressure slider directly fixes the sewing piece, the thorn, and the short thorn together, avoiding the situation where the worker cannot confirm the position of the short thorn before pressing it because the thorn has not yet passed through the sewing piece. Therefore, the step of initially passing the thorn through the sewing piece can be reduced, thereby improving work efficiency and further reducing the risk of the worker being scratched by the fixing thorn.

[0020] Preferably, in step S4, after the lower pressing surface slides into contact with the sewing lower piece, the pressing slider is removed from the slide rail plate, inverted, and reinstalled into the slide rail plate, with the upper pressing surface abutting against the sewing upper piece, and the pressing slider slides. By placing the upper and lower pressing surfaces within the same pressing slider and controlling different dimensions to ensure contact with binding straps of varying thicknesses, the number of pressing sliders required is reduced, preventing confusion among workers and improving work efficiency.

[0021] The beneficial effects of this invention are as follows:

[0022] (1) By inserting the fixing piercing into the binding strap, the binding strap is constrained in multiple directions to ensure the stability of the binding strap on the tool base plate. At the same time, the fixing piercing does not move during the fixing process, has a long service life, and is quick to install.

[0023] (2) The strapping is pressurized as a whole by the movement of the slide rail plate and the pressure slider. The pressurization effect is comprehensive and highly uniform, which can improve work efficiency.

[0024] (3) By arranging the puncture and short punctures at intervals, the staff can avoid contact with the fixed punctures, reduce the risk of scratches, and at the same time ensure that the staff can press the same area during the operation.

[0025] (4) By setting pressure protrusions and sliding pressure sliders of clearance grooves, the work efficiency of workers when piercing through sewing pieces is improved, and the risk of being scratched by fixed thorns is further reduced.

[0026] (5) By setting a lower pressing surface and an upper pressing surface on the front and back of the pressing slider, the need to replace different models of pressing sliders can be avoided, thereby improving the overall work efficiency;

[0027] (6) By opening the hand crank, interference with the binding strap is reduced. At the same time, by tilting the backboard, the degree of opening is ensured to be uniform. There is an angle between adjacent hand cranks to avoid mutual interference and to protect the staff from being pinched. Attached Figure Description

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] Example 1:

[0042] like Figure 1 , 2 As shown, a fixing fixture for a binding device includes a fixture base plate 1, on which a binding device assembly 2 is disposed. The binding device assembly 2 includes a binding host 21 and a binding strap 22. A sewing area 11 is disposed on the fixture base plate 1. The binding strap 22 includes a sewing upper piece 222 and a sewing lower piece 221. A fixing spike 3 is disposed next to the sewing area 11. When the binding device assembly 2 is fixed on the fixture base plate 1, the fixing spike 3 simultaneously penetrates the sewing upper piece 222 and the sewing lower piece 221.

[0043] A fixing spike 3 is set on the tooling base plate 1. After the binding host 21 is fixed, the binding strap 22 is pressed into the fixing spike 3 so that the area to be sewn on the binding strap 22 corresponds to the sewing area 11. Since the binding strap 22 is made by weaving and winding the thread during the production process, the fixing spike 3 can pierce the binding strap 22 through the gap between the threads. The fixing operation is simple and quick and does not damage the binding strap 22. The shape of the binding strap 22 fixed on the tooling base plate 1 will not change, ensuring that the surface of the binding strap 22 is flat. After the fixing spike 3 pierces the binding strap 22, the binding strap 22 obtains the limiting constraint in all directions except the vertical direction of the tooling base plate 1. When the sewing upper piece 222 is also pierced by the fixing spike 3, the binding strap 22 will not be pulled back or displaced, ensuring the stable positioning of the binding strap 22. At the same time, the fixing spike 3 will not move or deform during the fixing process. Therefore, the fixing spike 3 has a long service life and can adapt to the production line process of frequent disassembly and assembly.

[0044] like Figure 5 ,6 As shown, the fixed thorn 3 includes piercing thorns 31 and short thorns 32 arranged at intervals. The thickness of the sewing lower piece 221 is H1, the thickness of the sewing upper piece 222 is H2, the thickness of the piercing thorn 31 is h1, and the thickness of the short thorn 32 is h2, where h2 < H1 < h1 < H1 + H2. The fixing spikes 3 include piercing spikes 31 and short spikes 32. Piercing spikes 31 can pierce the lower sewing piece 221 and simultaneously pierce the upper sewing piece 222, but not pierce the upper sewing piece 222. Short spikes 32 only pierce the lower sewing piece 221, without piercing it. When installing the fixing straps 22, the lower sewing piece 221 is first fixed to the tool base plate 1. Since the short spikes 32 and piercing spikes 31 are arranged alternately, during fixing, after the piercing spikes 31 pass through the lower sewing piece 221, the worker can press the area between the two piercing spikes 31 with their fingers. Due to the impenetrability of the short spikes 32, the fixing of the lower sewing piece 221 is stable, while ensuring... To prevent staff from getting their fingers pricked, the binding strap 22 is then passed through the hook lock 212 inside the binding host 21 and then wrapped back onto the sewing area 11. The upper sewing piece 222 is fixed by the puncture 31. Since the lower sewing piece 221 will be subjected to a lot of pulling force during installation, the short thorns 32 and the puncture 31 are arranged alternately to ensure that the lower sewing piece 221 is stabilized by enough fixing thorns 3 while reducing the number of puncture holes formed by the lower sewing piece 221. At the same time, when the upper sewing piece 222 is pulled back to fix it, the short thorns 32 share the pulling force of the puncture 31, avoiding excessive deformation and displacement due to the high height of the puncture 31.

[0045] like Figure 3 , 4 As shown, several main fixtures 4 are provided on the tooling base plate 1. Each main fixture 4 has an inclined backing plate 41. A crank handle 211 is provided on the binding host 21. The inclined backing plate 41 abuts against the crank handle 211, and there is an angle difference α between the inclined backing plates 41 on adjacent main fixtures 4. During the fixing process of the binding host 21, the crank handle 211 needs to be opened to avoid interfering with the worker's fixing of the binding strap 22. This also facilitates the subsequent gripping of the sewn binding by the robotic arm. The inclined backing plate 41 limits the opening angle of the crank handle 211, ensuring a uniform opening angle. Furthermore, setting different inclination angles for adjacent inclined backing plates 41 creates an angle between adjacent crank handles 211. This prevents insufficient placement space due to the width of the crank handle 211 and avoids squeezing the worker's hand due to adjacent crank handles 211 being too close together during the opening process, thus protecting operational safety.

[0046] The assembly and operation process of the binding fixture in this embodiment is as follows: In this embodiment, multiple clamps are provided on the fixture base plate 1 for clamping the binding device, and a corresponding number of sewing areas 11 are provided. When the production line transports the binding fixture to the worker's workbench, the worker first fixes the binding host 21 and opens the crank 211, placing the crank 211 against the inclined backing plate 41, with different inclination angles between adjacent cranks 211. Then, the binding strap 22 is aligned with the sewing area 11, and the binding strap 22 is... The binding strap 22 is pressed into the fixing puncture 3 for pre-compression, so that the puncture 31 passes through the sewing lower piece 221. The worker then presses the position between the two punctures 31 to further fix the sewing lower piece 221. After passing the binding strap 22 through the hook lock 212, the sewing upper piece 222 is pulled back to the sewing area 11. Then, the sewing upper piece 222 is pressed directly down and inserted into the puncture 31 to fix the sewing upper piece 222. The above operation is then repeated for the remaining binding devices to complete the binding device fixing operation.

[0047] Example 2:

[0048] like Figure 7 , 8 As shown, unlike Embodiment 1, in this embodiment, slide rails 12 are provided on both sides of the sewing area 11. A pressure slider 13 is detachably connected to the slide rail 12. The pressure slider 13 is provided with a plurality of pressure protrusions 131 on the side near the tool base plate 1. A clearance groove 132 is provided between adjacent pressure protrusions 131. The pressure protrusions 131 correspond to the short thorns 32, and the clearance grooves 132 correspond to the punctures 31.

[0049] When the fixed barb 3 is provided with short barbs 32 and punctures 31, the pressure slider 13 is provided with corresponding pressure protrusions 131 and clearance grooves 132. When the sewing piece 221 is flattened and pressured by the pressure slider 13, the position corresponding to the pressure protrusion 131 is the area of ​​the short barbs 32, and the position corresponding to the clearance groove 132 is the area of ​​the punctures 31. Thus, the pressure protrusion 131 simulates the manual pressing of the worker, improving the efficiency of fixing the binding strap 22. At the same time, since the distance between the slide rails 12 is uniform, the pressure slider 13 is installed on the slide rails 12. When the pressure protrusion 131 corresponds to the area of ​​the short thorn 32, there is no need to press the binding strap 22 initially to expose the thorn 31, which simplifies the fixing and installation steps of the sewing lower piece 221. After the sewing lower piece 221 is fixed, the pressure slider 13 can be removed from the slider mounting port 122 to install the sewing upper piece 222. Since the slider mounting port 122 is a notch set on the slide rail plate 12, the sewing needle moves horizontally through the slider mounting port 122 during the sewing process to realize the sewing connection of multiple sewing tapes on the tool base plate 1.

[0050] Example 3:

[0051] like Figure 9 As shown, unlike Embodiment 2, in this embodiment, the pressure slider 13 can be mounted on the slide rail 12 in both directions and can slide relative to it. The pressure slider 13 includes a lower pressure surface 133 and an upper pressure surface 134. The thickness of the lower sewing piece 221 is H1, and the thickness of the upper sewing piece 222 is H2. When the lower pressure surface 133 is positioned close to the tooling base plate 1, the distance between it and the tooling base plate 1 is A1. When the upper pressure surface 134 is positioned close to the tooling base plate 1, the distance between it and the tooling base plate 1 is A2. A1 = H1, A2 = H2 + H1. (In the illustration, a gap is left between the pressure slider and the binding strap for clarity; in reality, they are in a fitted state.)

[0052] The pressure slider 13 has a lower pressing surface 133 and an upper pressing surface 134 on its front and back sides. The pressure slider 13 can be mounted on the slide rail 12 in both directions and slide relative to each other. By mounting the pressure slider 13 in both directions, the upper sewing piece 222 or the lower sewing piece 221 can be fixed and pressed respectively, which improves the fixing efficiency and protects the labor intensity of the workers. The pressure slider 13 further includes a sliding block and a pressure block. The sliding block is detachably connected to the slide rail 12, and the pressure block is rotatably connected to the sliding block.

[0053] Example 4:

[0054] like Figure 10 As shown, this embodiment discloses a method for securing a strapping device, which includes the following steps:

[0055] S1. Fix the binding host 21 onto the tool base plate 1, and align the sewing lower piece 221 with the sewing area 11.

[0056] S2. Press the sewing piece 221 into the fixed thorn 3. The pressing position on the sewing piece 221 corresponds to the short thorn 32 above it. The short thorn 32 pierces into the sewing piece 221, and the thorn 31 pierces through the sewing piece 221 and then pierces out.

[0057] S3. After passing the sewing piece 222 through the binding host 21, align it with the sewing area 11;

[0058] S4. Press the sewing upper piece 222 into the fixing puncture 3. The pressing position on the sewing upper piece 222 is the entire upper surface of the sewing upper piece 222. The puncture 31 pierces into the sewing upper piece 222.

[0059] In step S2, the pressure slider 13 is connected to the slide rail plate 12 and slides along the slide rail plate 12, and the pressure protrusion 131 abuts against the upper surface of the sewing piece 221 corresponding to the short barb 32.

[0060] In step S4, after the lower piece pressure surface 133 slides into contact with the sewing lower piece 221, the pressure slider 13 is removed from the slide rail plate 12, inverted and reinstalled into the slide rail plate 12, the upper piece pressure surface 134 abuts against the sewing upper piece 222, and the pressure slider 13 slides.

[0061] After securing the binding host 21 to the tooling base plate 1, flatten the sewing lower piece 221 and align it with the sewing area 11. Press down on the sewing lower piece 221 so that the piercing 31 passes through it. Then, press the area between the two piercing 31s with your fingers to press the sewing lower piece 221 a second time, ensuring that the piercing 31s completely penetrate the sewing lower piece 221 and the short thorns 32 penetrate into it. After securing the sewing lower piece 221, pass the binding strap 22 through the hook lock 212 and secure the hook lock 212 to the tooling base plate 1. Then, pull back the sewing upper piece 222 to secure it through the piercing 31s. During the sewing process, when the sewing needle begins its first stitch, the upper sewing piece 222 and the lower sewing piece 221 are fixedly connected. Therefore, during the sewing process, only one side of the upper sewing piece 222 or the lower sewing piece 221 needs to be stably fixed by the fixing thorns 3 to maintain overall fixation. This method ensures the number of fixing thorns 3 and effectively avoids excessive punctures 31 that could create too many holes in the lower sewing piece 221. Furthermore, because the thorns 31 are relatively long and thin, and the short thorns 32 are small in size and have a small deformation displacement, the thorns 31 can be prevented from breaking during the pullback of the upper sewing piece 222. The lower sewing piece 221 is then fixedly connected to the upper sewing piece 222, thereby constraining the upper sewing piece 222 and preventing it from shifting from the lower sewing piece 221 when it is transported to the sewing machine area after installation. Furthermore, this method ensures that when pressing the lower sewing piece 221, the pressing area is fixed between the two punctures 31, avoiding the risk of operator injury from the punctures 31. It also unifies the pressing actions and areas of each operator, improving the uniformity of the binding strap 22's installation. During the operator's application of pressure to the lower sewing piece 221, the pressure slider 13 directly presses the sewing piece... The sewing piece 221 is fixed together with the piercing 31 and the short thorn 32 to prevent the worker from not being able to confirm the position of the short thorn 32 before pressing it because the piercing 31 has not yet passed through the sewing piece 221. Therefore, the step of initially passing the piercing 31 through the sewing piece 221 can be reduced, thereby improving work efficiency. At the same time, it further reduces the risk of the worker being scratched by the fixed thorn 3. The upper pressing surface 134 and the lower pressing surface 133 are set in the same pressing slider 13, and different sizes are controlled to ensure that they can abut against the binding straps 22 of different thicknesses, thereby reducing the number of pressing sliders 13 and preventing the worker from getting confused and reducing work efficiency.

[0062] Example 5:

[0063] like Figure 11 As shown, unlike Embodiment 1, in this embodiment, the slide rail 12 is an arc-shaped spring piece 121. When the binding strap 22 is fixed on the sewing area 11, the arc-shaped spring piece 121 abuts against both sides of the binding strap 22, and simultaneously abuts against the edge of the upper sewing piece 222 away from the lower sewing piece 221. By setting the slide rail 12 into the shape of an arc-shaped spring piece 121, when the binding strap 22 is placed between the slide rail 12, the slide rail 12 can provide vertical limiting constraint on the binding strap 22.

[0064] In addition to the above embodiments, within the scope disclosed in the claims and specification of this invention, the technical features of this invention can be reselected and combined to form new embodiments.
