Description

Technical Field

[0001] This utility model relates to staple production equipment, and more specifically, to a staple thread plate adhesive pretreatment device. Background Technology

[0002] In the production process of staples, thin metal wires need to be fed side by side and arranged closely together. The arranged metal wires are coated with glue by the gluing mechanism, and then the glue is cured by the heating mechanism, which bonds the metal wires to form a sheet of metal wire. The sheet of metal wire is then cut and shaped to obtain the desired staple product.

[0003] During the glue application process, the relatively smooth surface of the metal wires leads to poor glue adhesion, which can easily result in glue leakage or insufficient glue. This affects the bonding strength and uniformity between the metal wires, and consequently the quality of the metal wire board and the final staple product.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a staple thread board glue pretreatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a staple thread board glue pretreatment device, comprising a frame and a support roller one, a wiping table, and a support roller two mounted on the frame. The support roller one and the support roller two are respectively located on both sides of the wiping table. The support roller two is located on the output side of the metal wire and is rotatably connected to the frame. A flexible wiping part is provided on the upper side of the wiping table for wiping the metal wire. The support roller one can be fixed relative to the frame for rubbing against the surface of the metal wire.

[0007] The present invention is further configured such that an upper platform is formed on the upper side of the wiping table, and a groove is provided on the upper platform. The wiping part is partially embedded in the groove and partially protrudes upward from the upper platform.

[0008] The present invention is further configured such that the wiping part is a flexible fabric or sponge.

[0009] The present invention is further configured such that the metal wire passes over the upper side of the first support roller and the second support roller, and the highest position of the upper side of the first support roller and the second support roller is higher than the upper surface of the wiping table and lower than the upper side of the wiping part; the metal wire can be embedded in the upper side of the wiping part.

[0010] The present invention is further configured such that the support roller has a rough surface, which is used to form a rough surface by friction with the surface of the metal wire.

[0011] The present invention is further configured such that the two ends of the first support roller are rotatably connected to the first support base and the second support base, respectively, and are locked and fixed by locking bolts.

[0012] The present invention is further configured such that two locking bolts are rotatably connected to support base one and support base two respectively, and the ends of the locking bolts can be pressed and locked against support roller one.

[0013] The present invention is further configured such that: the first support base is installed on the frame by a first bolt, the first support base can be adjusted to deflect around the first bolt, and the first bolt passes through the first support base vertically; the second support base is installed on the frame by a second bolt, the frame is provided with a guide groove, the guide groove is arc-shaped around the first bolt, and the second bolt slides and adjusts along the guide groove.

[0014] The present invention is further configured such that at least two sets of the second bolts are provided, and both of them penetrate downward through the guide groove and are locked and fixed by nuts.

[0015] The present invention is further configured to include two wire breakage detection rods, which are arranged parallel to each other vertically, with a metal wire passing between the two wire breakage detection rods; when the metal wire breaks, it can contact at least one wire breakage detection rod, thereby connecting the wire breakage detection rod and the support roller to achieve a wire breakage indication.

[0016] In summary, this utility model has the following beneficial effects:

[0017] By setting up a support roller, the support roller can be fixed in the working state. The metal wire passes over the upper side of the support roller, and friction is generated at the contact point between the two. This friction can create a rough surface on the lower side of the metal wire. When applying glue, the rough surface can improve the adhesion of the glue and enhance the bonding effect after application. During the glue application process, the glue can easily adhere to the rough surface on the lower side of the metal wire and overflow into the gaps between the metal wires through the tension of the glue, thereby enabling the metal wires to be stably and evenly bonded.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] This embodiment discloses a staple thread board glue pretreatment device, referring to... Figures 1-3 As shown, the device is located before the metal wire 2 is coated and bonded with adhesive. It includes a frame 1 and a support roller 3, a wiping table 4, and a support roller 5 installed on the frame 1. The support roller 3 and the support roller 5 are located on both sides of the wiping table 4, and the support roller 5 is located on the output side of the metal wire 2, that is, closer to the adhesive coating equipment.

[0027] The second support roller 5 is rotatably connected to the frame 1. The metal wire 2 passes over the upper side of the second support roller 5, which can guide and position the metal wire 2. A flexible wiping part 41 is provided on the upper side of the wiping table 4. The wiping part 41 is a flexible fabric or sponge that plays the role of wiping and cleaning the metal wire 2.

[0028] The support roller 3 is supported at both ends by support base 31 and support base 32 respectively. The support roller 3 can be fixed relative to the frame 1 and is used to rub against the surface of the metal wire 2. In use, the support roller 3 is in a fixed state, and the metal wire 2 passes over the upper side of the support roller 3. Friction occurs at the contact point between the two, which rubs against the lower side of the metal wire 2, forming a rough surface. This rough surface improves the adhesion of the adhesive when applying it, thus enhancing the bonding effect after application. Furthermore, the rough surface of the metal wire, after the staple is formed, is located on the inside of the staple and will not affect its stability.

[0029] Reference Figure 3As shown, an upper platform 40 is formed on the upper side of the wiping table 4. The upper platform 40 has a groove 42. The wiping part 41 is partially embedded in the groove 42 and partially protrudes upward from the upper platform 40. The groove 42 can accommodate the wiping part 41 and limit the wiping part 41, so that the wiping part 41 has a certain thickness, which can improve the oil absorption and dirt holding effect of the wiping part 41.

[0030] The highest point of the upper side of support roller 3 and support roller 5 is higher than the upper surface 40 of the wiping table 4, but lower than the upper side of the wiping part 41. The metal wire 2 passes over the upper side of support roller 3 and support roller 5. When passing over the upper surface 40 of the wiping table 4, it can avoid direct frictional contact with the upper surface 40, and can also embed the metal wire 2 into the upper side of the wiping part 41, so that the metal wire 2 can achieve the wiping and cleaning effect.

[0031] The friction between the support roller 3 and the metal wire 2 allows the surface of the support roller 3 to be roughened, forming a rough surface through friction with the surface of the metal wire 2. To improve the friction effect, knurling can be pre-processed on the outer periphery of the support roller 3, or it can be sanded with sandpaper to create a relatively rough state.

[0032] For support roller 3, both ends of support roller 3 are rotatably connected to support base 31 and support base 32 respectively, and are locked and fixed by locking bolts 33. The two locking bolts 33 are rotatably connected to support base 31 and support base 32 respectively, and the ends of the locking bolts 33 can press against and lock support roller 3.

[0033] When in use, the support roller 3 is locked and fixed. If the support roller 3 is in contact with the metal wire 2 at the same position for a long time, the friction position of the support roller 3 will be significantly worn, and may even cause the upper side of the support roller 3 to be dented.

[0034] After a period of use, the locking bolt 33 can be loosened, and the support roller 3 can be rotated and adjusted to adjust the friction contact position between the support roller 3 and the metal wire 2, thereby avoiding significant friction loss due to long-term wear of the support roller 3; after adjustment, the locking bolt 33 can be tightened to lock and fix the support roller 3.

[0035] Furthermore, in this embodiment, the device also includes two wire breakage detection rods 6, which are arranged parallel to each other vertically and supported by a detection frame 61. The metal wire 2 passes between the two wire breakage detection rods 6. A support roller 3 is connected to one end of the detection circuit, and the two wire breakage detection rods 6 are connected to the other end of the detection circuit. When the metal wire 2 breaks, it will either tilt upwards or sag and fall, making contact with at least one wire breakage detection rod 6. The metal wire 2 can then conduct electricity between the wire breakage detection rod 6 and the support roller 3, forming an alarm signal to indicate a wire breakage. For example, an audible and visual alarm can be used. In this embodiment, only the connection structure of the two terminals of the detection circuit is described. The specific form of the detection circuit has been disclosed in the applicant's previous patent (CN216622246U A Wire Breakage Detection Mechanism for a Staple Production Line), and will not be repeated here.

[0036] Example 2

[0037] This embodiment discloses a staple thread board glue pretreatment device, which is based on Embodiment 1 and refers to... Figure 4 , Figure 5 A detailed explanation is provided below. To prevent the support roller 3 from rubbing against the metal wire 2 from the same position for an extended period of time, the support roller 3 can be deflected to change the position of frictional contact between the support roller 3 and the metal wire 2.

[0038] Specifically, refer to Figure 4 , Figure 5 As shown, the support base 31 is installed on the frame 1 by the first bolt 311. The support base 31 can be adjusted by deflection around the first bolt 311. The first bolt 311 passes through the support base 31 vertically. The lower end of the first bolt 311 can be directly threaded to the frame 1.

[0039] The second support base 32 is mounted to the frame 1 by the second bolt 321. The frame 1 has a guide groove 11, which is arc-shaped around the first bolt 311. The second bolt 321 slides and adjusts along the guide groove 11. In order to improve the stability after locking, 2-3 sets of second bolts 321 can be set, all of which penetrate downward through the guide groove 11 and are locked at the lower end of the second bolt 321 by nuts.

[0040] During the adjustment process, the first bolt 311 and the second bolt 321 can be loosened, and the support base 31, the support roller 3, and the support base 32 can be adjusted and rotated around the first bolt 311, so that one end of the support roller 3 can tilt and sway along the forward and backward conveying direction of the metal wire 2. After the tilt and sway are adjusted, the first bolt 311 and the second bolt 321 can be tightened and fixed again.

[0041] After tilting and swaying, the contact position between the upper side of the support roller 3 and the metal wire 2 can also be adjusted, thereby further changing the contact position between the support roller 3 and the metal wire 2. This adjustment method can be used in conjunction with the rotation adjustment of the support roller 3 to ensure that the wear on the outer circumference of the support roller 3 is as uniform as possible, and to extend the service life of the support roller 3. In addition, shims can also be installed on the lower side of the support base 1 and the support base 2 32, between them and the frame 1, to adjust the height of the support roller 3 so that the height of the support roller 3 is kept in a reasonable and appropriate position.

[0042] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
