Description

Technical Field

[0001] This utility model relates to the technical field of sealing strip processing equipment, specifically to a tooling for edge wrapping and flocking of sealing strips. Background Technology

[0002] Sealing strips are widely used in automobiles, doors and windows, and other fields, mainly for waterproofing, dustproofing, noise reduction, and sealing. To improve the aesthetics and practicality of sealing strips, flocking material is often applied to the edge of their sealing lip to improve the feel, reduce noise and friction, and enhance the overall assembly quality.

[0003] Traditional edge-sealing and flocking processes typically involve first extruding the sealing strip into shape, then cooling it before applying flocked tape to the edge of the sealing lip through heating, bonding, or secondary lamination. However, these methods are complex, require large amounts of equipment, consume a lot of energy, and suffer from problems such as unstable bonding strength, low efficiency, and poor automation, making it difficult to meet the needs of efficient and continuous production. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a tooling for edge wrapping and flocking of sealing strips, so as to solve the problems of the traditional edge wrapping and flocking process of sealing strips, which adopts a secondary processing method of extrusion followed by bonding, resulting in a complicated process, high energy consumption, and unstable bonding quality, making it difficult to meet the needs of efficient and continuous production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tooling for attaching fleece to the edge of a sealing strip, installed on an extrusion die, includes:

[0007] The mounting bracket is located on the discharge side of the extrusion die and is equipped with a guide block for guiding the sealing lip of the sealing strip into the flocked tape.

[0008] At least one edge-binding component, including a positioning block and an edge-binding block disposed on the positioning block;

[0009] An adjusting component, connecting the mounting bracket and the positioning block, is used to adjust the relative distance between the positioning block and the edge-sealing block and the extruded section of the sealing strip.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. By directly installing this fixture on the discharge side of the extrusion die, the guide block, positioning block, and edge-sealing block work together to ensure precise alignment of the flocked tape and the sealing lip of the sealing strip, avoiding misalignment and wrinkles. Utilizing the high temperature immediately after extrusion, the flocked tape's base film melts rapidly and simultaneously adheres to the sealing lip, eliminating the need for a secondary heating process and improving efficiency. Furthermore, because the flocked tape is melted and adhered at the high temperature of the sealing lip, the bond is tighter, the adhesion is stronger, and it is less prone to detachment.

[0012] 2. The adjustable parts allow for flexible adjustment of the relative position of the edge-sealing components to accommodate the different requirements of the felt application position of the sealing strips, thus improving its versatility and applicability.

[0013] Furthermore, the guide block has a guide groove; the positioning block has a mounting surface, and the edge-sealing block has an edge-sealing surface, the mounting surface and the edge-sealing surface being adapted to the sealing lip of the sealing strip.

[0014] Furthermore, the guide groove includes a large-diameter end and a small-diameter end, the inner diameter of which gradually decreases from the large-diameter end to the small-diameter end, and the large-diameter end is close to the discharge side of the extrusion die.

[0015] Furthermore, the adjusting component includes an adjusting block and a pressing bolt threaded to the adjusting block; the mounting frame includes a fixing block disposed on the discharge side of the extrusion die and an adjusting frame mounted on the fixing block, the adjusting block being slidably disposed on the adjusting frame, and the end of the pressing bolt abutting against the adjusting frame.

[0016] Furthermore, the adjusting bracket is connected to the fixing block via a first adjusting bolt, so as to adjust the distance between the edge block and the lip of the sealing strip via the first adjusting bolt.

[0017] Furthermore, the positioning block is connected to the adjusting frame via a second adjusting bolt, so as to adjust the distance between the positioning block and the lip tip of the sealing strip via the second adjusting bolt.

[0018] Furthermore, the fixing block is connected to the extrusion die via a third adjusting bolt.

[0019] Furthermore, the guide block is connected to the fixing block via a fourth adjusting bolt. Attached Figure Description

[0032] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance.

[0034] like Figure 1-5 As shown in the figure, this utility model embodiment proposes a tooling for edge banding and flocking of a sealing strip, which is installed on an extrusion die 9 and includes a mounting frame 1, at least one edge banding component 3, and an adjusting component 4. The mounting frame 1 is located on the discharge side of the extrusion die 9 and is equipped with a guide block 2 for guiding the sealing lip of the sealing strip 10 into the flocked tape 11. The edge banding component 3 includes a positioning block 31 and an edge banding block 32 disposed on the positioning block 31. The adjusting component 4 connects the mounting frame 1 and the positioning block 31 and is used to adjust the relative distance between the positioning block 31 and the edge banding block 32 and the extrusion section of the sealing strip 10.

[0035] In this embodiment of the invention, the tooling is installed on the discharge side of the extrusion die 9 during use. After the sealing strip 10 is formed by the extrusion die 9, it is still at a high temperature. Its sealing lip, guided by the guide block 2, accurately enters the pre-positioned flocked tape 11, forming a preliminary fit. Subsequently, the positioning block 31 in the edge-wrapping assembly 3 ensures that the edge-wrapping block 32 and the sealing lip are in the correct position. The edge-wrapping block 32 then presses and shapes the flocked tape 11, causing its base film to melt under the high temperature of the sealing lip and firmly adhere to the lip surface, completing the edge-wrapping and flocking operation. Furthermore, through the adjustment of the adjusting component 4, the distance between the positioning block 31 and the edge-wrapping block 32 relative to the extruded section of the sealing strip 10 can be adjusted according to different specifications of the sealing strip 10 or the requirements of the flocking process, achieving flexible adaptation and improving its versatility and applicability. Moreover, this tooling can be used in conjunction with an extrusion production line to achieve continuous and automated edge-wrapping and flocking operations, reducing manual intervention and improving overall production efficiency.

[0036] Specifically, such as Figure 3-4As shown in the embodiment of this utility model, the guide block 2 has a guide groove 21; the positioning block 31 has a mounting surface 311, and the edge-wrapping block 32 has an edge-wrapping surface 321. The mounting surface 311 and the edge-wrapping surface 321 are adapted to the sealing lip of the sealing strip 10. The guide groove 21 includes a large diameter end and a small diameter end. The inner diameter of the large diameter end gradually decreases from the small diameter end to the large diameter end. The large diameter end is close to the discharge side of the extrusion die 9, and the transition from the large diameter end to the small diameter end is a smooth contraction. The guide groove 21 has a gradually narrowing guide structure, which improves the smoothness of the sealing strip 10 in guiding the flocking tape 11, so that it accurately enters the edge-wrapping area, reduces the offset, and improves the accuracy and consistency of the flocking position, thereby improving the efficiency of the entire edge-wrapping and flocking process and the finished product qualification rate.

[0037] During use, the guide groove 21 guides the sealing lip of the extruded sealing strip 10 into the inside of the flocked tape 11 during the movement process, forming an initial fit position relationship. Subsequently, the mounting surface 311 of the positioning block 31 and the edge-wrapping surface 321 of the edge-wrapping block 32 enable the flocked tape 11 to closely fit the surface of the sealing lip when the flocked tape is applied, thereby enhancing the fusion bonding effect between the flocked tape 11 and the sealing strip 10.

[0038] Specifically, such as Figure 3 As shown in the embodiment of this utility model, the adjusting member 4 includes an adjusting block 41 and a pressing bolt 42 threadedly connected to the adjusting block 41; the mounting frame 1 includes a fixing block 101 disposed on the discharge side of the extrusion die 9 and an adjusting frame 102 mounted on the fixing block 101. The adjusting block 41 is slidably disposed on the adjusting frame 102, and the end of the pressing bolt 42 abuts against the adjusting frame 102. By rotating the pressing bolt 42, the adjusting block 41 can be pushed to slide on the adjusting frame 102, thereby driving the positioning block 31 and the edge-binding block 32 connected to the adjusting block 41 to achieve displacement, which facilitates the control of the relative position between the edge-binding member and the lip of the sealing strip 10 to meet different velour application requirements.

[0039] Based on the above solutions, such as Figure 5 As shown in this embodiment of the present invention, the adjusting frame 102 is connected to the fixing block 101 by the first adjusting bolt 5, so as to adjust the distance between the edging block 32 and the lip edge of the sealing strip 10 by the first adjusting bolt 5; the positioning block 31 is connected to the adjusting frame 102 by the second adjusting bolt 6, so as to adjust the distance between the positioning block 31 and the lip tip of the sealing strip 10 by the second adjusting bolt 6. The first adjusting bolt 5 and the second adjusting bolt 6 are used to adjust the contact position and contact distance between the mounting surface 311 of the positioning block 31 and the edging surface 321 of the edging block 32 and the sealing lip of the sealing strip 10, so as to meet the requirements of the felt application.

[0040] Based on the above solutions, such as Figure 5As shown in this embodiment of the utility model, the fixing block 101 is connected to the extrusion mold 9 by the third adjusting bolt 7. The third adjusting bolt 7 serves as a connection and adjustment mechanism between the fixing block 101 and the extrusion mold 9, which can accurately position the entire edge-wrapping and flocking fixture relative to the discharge port of the extrusion mold 9, ensuring that the flocking assembly is aligned with the extrusion section of the sealing strip 10.

[0041] Specifically, such as Figure 3 As shown in this embodiment of the utility model, the guide block 2 is connected to the fixed block 101 by the fourth adjusting bolt 8. The fourth adjusting bolt 8 enables the guide block 2 to be independently fine-tuned on the fixed block 101, thereby precisely controlling the angle and guiding starting point of the guide groove 21, and ensuring that the lip of the sealing strip 10 smoothly enters the edge area of ​​the flocked tape 11.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
