Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, specifically relating to a high-thrust, high-precision servo pressing and edge-wrapping machine. Background Technology

[0002] In the footwear, bag, and textile industries, edge binding and bonding of certain materials is frequently required. Traditional edge binding and bonding is primarily done manually, using pressing and folding mechanisms. In the pressing process, cylinders typically drive pressure blocks directly for pressing and maintaining pressure. This method suffers from poor processing precision and inconsistent force retention, especially when working with low-strength materials like EVA. Controlling the downward pressure is difficult, leading to poor bonding results or even product damage. Furthermore, current edge binding operations mainly rely on molds and spade-like structures, which are relatively complex and inefficient. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a high-thrust, high-precision servo pressing and edge banding machine, which solves the problems of difficult pressure control, low precision, complex edge banding mold movements, and low efficiency of existing pressing and edge banding machines.

[0004] This utility model is achieved through the following technical solution: a high-thrust, high-precision servo pressing and edge-sealing machine, comprising a main worktable, a servo pressing device mounted above the main worktable, and an edge-sealing mold mounted on the main worktable; wherein: the servo pressing device comprises an upper fixed main board, a movable frame plate located below the upper fixed main board, a lower pressure plate assembly mounted on the lower surface of the movable frame plate, a motor bracket mounted on the rear of the upper surface of the upper fixed main board, a reducer and a servo motor mounted on the motor bracket, and a lead screw and nut assembly longitudinally mounted in the middle of the upper fixed main board; wherein, the servo motor and the reducer are connected to the lead screw and nut assembly via a transmission mechanism, the lead screw and nut are rotatably mounted on the upper fixed main board via a lead screw and nut seat, and the lower end of the lead screw of the lead screw and nut assembly passes through the upper fixed main board and is connected to the movable frame plate below;

[0005] The edging mold includes a mold base, a lower template mounted on the mold base, and a front positioning template and a rear positioning template respectively mounted on the mold base and located before and after the lower template. The lower template has several main material limiting concave surfaces, and the upper outer periphery of each main material limiting concave surface is also formed with an edging auxiliary material positioning step surface that connects to the sidewall of the main material limiting concave surface. The front and rear positioning templates each have a main material positioning part equal in number to the main material limiting concave surfaces, and a set of opposing main material positioning parts on the front and rear positioning templates are aligned. The mold forms a main material positioning cavity. When the main material is placed in the main material positioning cavity, the upper end of the main material protrudes from the upper surface of the front and rear positioning templates, and the protrusion height is not less than the depth of the main material limiting concave surface. This ensures that the main material and auxiliary material can be fully compacted when pressed together, and avoids the main material falling entirely into the main material positioning cavity and the pressing force being insufficient. The mold base is also equipped with template driving cylinders and template guide rail mechanisms that drive the front and rear positioning templates respectively. That is, the front and rear positioning templates move in opposite directions through the template driving cylinders to perform mold opening and closing actions.

[0006] The upper fixed main board of the servo pressing device is connected to the four corners of the main worktable through four columns; four sets of first longitudinal guide rail assemblies passing through the movable frame plate are also installed between the upper fixed main board and the main worktable, and the movable frame plate moves up and down along the first longitudinal guide rail assemblies; two second longitudinal guide rail assemblies are also connected to the movable frame plate, and the second longitudinal guide rail assemblies pass through the upper fixed main board with the upper end of the second longitudinal guide rail assembly facing upward, and the upper end of the second longitudinal guide rail assembly is connected to the upper end of the lead screw of the lead screw nut assembly through a connecting plate.

[0007] A support frame is connected to the rear of the main workbench and the upper fixed motherboard. A positioning sensor is installed on the support frame, and a baffle corresponding to the positioning sensor is installed at the rear of the movable frame plate.

[0008] The main body of the support frame is equipped with an adjustment groove.

[0009] The lower pressure plate assembly includes an upper transition plate connected to the lower surface of the movable frame plate, a lower transition plate connected to the upper transition plate via five equal-height connecting columns, and a lower pressure plate installed on the lower surface of the lower transition plate; the five equal-height connecting columns are distributed at the four corners and the middle of the upper and lower transition plates.

[0010] The lower template is equipped with a heating module.

[0011] This invention utilizes the aforementioned equipment, employing a servo motor and reducer to drive the lead screw and pressing assembly for pressing action. This achieves a high-precision, high-thrust pressing effect, improving the accuracy of product pressing, especially for edge binding operations on EVA material main materials. Furthermore, this invention, in conjunction with an edge binding mold, can simultaneously perform pressing and edge binding operations on multiple products, thereby increasing efficiency.

[0013] Figure 3 , Figure 4 This is a schematic diagram of the edge-wrapping mold in this utility model. Detailed Implementation

[0014] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0015] like Figure 1 , Figure 2 As shown, this utility model describes a high-thrust, high-precision servo pressing and edge-sealing machine, including a main worktable 1, a servo pressing device 2 mounted above the main worktable 1, and an edge-sealing mold 3 mounted on the main worktable 1; wherein: the servo pressing device 2 includes an upper fixed main plate 21, a movable frame plate 22 located below the upper fixed main plate 21, a lower pressure plate assembly 23 mounted on the lower surface of the movable frame plate 22, a motor bracket 24 mounted on the rear of the upper surface of the upper fixed main plate 21, a reducer 25 and a servo motor 26 mounted on the motor bracket 24, and a lead screw and nut assembly 27 longitudinally mounted in the middle of the upper fixed main plate 21; wherein, the servo motor 26 and the reducer 25 are connected to the lead screw and nut assembly 27 via a transmission mechanism 251, the lead screw 270 is rotatably mounted on the upper fixed main plate 21 via a lead screw seat 271, and the lower end of the lead screw 272 of the lead screw and nut assembly 27 passes through the upper fixed main plate 21 and is connected to the movable frame plate 22 below;

[0016] The lead screw nut of the lead screw nut assembly 27 rotates under the drive of the transmission mechanism 251, causing the lead screw 272 to move up and down, which in turn drives the movable frame plate 22 and the lower pressure plate assembly 23 below it to move up and down, thereby realizing the pressing and lifting actions; the servo motor 26 can convert high speed and low torque into low speed and high torque transmission through the reducer 25, thereby generating a high thrust and high precision pressing action to the movable frame plate 23 and the lower pressure plate assembly 24 through the lead screw 272;

[0017] Combination Figure 3 , Figure 4As shown, the edge-binding mold 3 includes a mold base 31, a lower template 32 disposed on the mold base 31, and a front positioning template 33 and a rear positioning template 34 respectively mounted on the mold base 31 and located in front of and behind the lower template 32; the lower template 32 is provided with several main material limiting concave surfaces 321, the shape of which matches the shape of the end face of the main material to be edged; the upper outer periphery of each main material limiting concave surface 321 is also formed with an edge-binding auxiliary material positioning step surface 322 that connects to the side wall of the main material limiting concave surface 321; the front positioning template 33 and the rear positioning template 34 are respectively formed with main material positioning parts 331 and 341 in number equal to the number of main material limiting concave surfaces 321, and the front positioning template 33... A set of opposing main material positioning parts 331 and 341 of the rear positioning template 34 form a main material positioning cavity 300 when the mold is closed. When the main material is placed in the main material positioning cavity 300, the upper end of the main material protrudes from the upper end surface of the front and rear positioning templates and the protrusion height is not less than the depth of the main material limiting concave surface 321. This ensures that the main material and auxiliary material can be fully compacted when pressed together, and avoids the main material falling into the main material positioning cavity 300 and the pressing force being insufficient. The mold base 31 is also provided with a template driving cylinder 35 and a template guide rail mechanism 351 that drive the front positioning template 33 and the rear positioning template 34 respectively. That is, the front positioning template 33 and the rear positioning template 34 perform mold opening and mold closing actions by moving towards each other through the template driving cylinder 35 respectively.

[0018] The upper fixed main board 21 of the servo pressing device 2 is connected to the four corners of the main worktable 1 through four columns 211; four sets of first longitudinal guide rail assemblies 212 passing through the movable frame plate 22 are also installed between the upper fixed main board 21 and the main worktable 1, and the movable frame plate 22 moves up and down along the first longitudinal guide rail assemblies 212; two second longitudinal guide rail assemblies 221 are also connected to the movable frame plate 22, and the second longitudinal guide rail assemblies 221 pass through the upper fixed main board 21 with their upper ends facing upwards. The upper ends of the second longitudinal guide rail assemblies 221 are connected to the upper ends of the lead screw 272 of the lead screw nut assembly 27 through a connecting plate 222, that is, the two second longitudinal guide rail assemblies 221 make the rise and fall of the lead screw 272 more stable and more accurate.

[0019] A support frame 11 is connected to the rear of the main worktable 1 and the upper fixed motherboard 21. Two positioning sensors 12 are installed on the support frame 11, and a baffle 223 corresponding to the positioning sensors 12 is installed at the rear of the movable frame plate 22. The baffle 223 and the positioning sensors 12 are used to precisely control the stroke of the servo motor 26 driving the movable frame plate 22 and the lower pressure plate assembly 23, thereby achieving the purpose of high-precision pressing.

[0020] The main body of the stand 11 is provided with an adjustment groove 111 to adjust the position of the upper and lower positioning sensors, thereby adapting to the pressing needs of products of different specifications.

[0021] The lower pressure plate assembly 23 includes an upper transition plate 231 connected to the lower surface of the movable frame plate 22, a lower transition plate 233 connected to the upper transition plate 231 via five equal-height connecting columns 232, and a lower pressure plate 234 installed on the lower surface of the lower transition plate 233. The five equal-height connecting columns 232 are distributed at the four corners and the middle of the upper and lower transition plates, which can make the downward pressure of the lower pressure plate assembly 23 stably and evenly applied to the product, avoiding uneven pressing and improving pressing accuracy.

[0022] The lower template 32 is equipped with a heating module (not shown in the figure). This is used in situations such as hot melt adhesive being applied to the edge-sealing auxiliary material. When pressing together, the lower template is heated, causing the hot melt adhesive on the edge-sealing auxiliary material to melt and press together with the main material for edge sealing.

[0023] Before the pressing operation, the edge-binding mold 3 is in the open state, that is, the front positioning template 33 and the rear positioning template 34 are separated, and the lower template 32 and its main material limiting concave surface 321 and edge-binding auxiliary material positioning step surface 322 are all exposed upwards. At this time, the edge-binding auxiliary material coated with adhesive is first placed on the edge-binding auxiliary material positioning step surface 322 that matches its shape. Then, the template drive cylinder 35 is activated to close the front positioning template 33 and the rear positioning template 34, forming the main material positioning cavity 300. The main material is then placed into the main material positioning cavity 300, so that its lower end face contacts the edge-binding auxiliary material and its upper end face protrudes from the upper surface of the positioning template. The servo pressing device 2 at the rear and upper part is activated, and the lower pressure plate assembly 23 is pressed downward through the servo drive component. The lower pressure plate 234 at the bottom of the lower pressure plate assembly 23 directly presses against the upper end surface of the main material and is precisely positioned and pressed down by the servo motor 26, so that both the main material and the edging auxiliary material are embedded in the main material limiting concave surface 321. Under the action of the side wall of the main material limiting concave surface 321, the edging auxiliary material is wrapped together with the side of the main material, realizing the integrated pressing and edging operation. After pressing for a few seconds or a period of time, the front and rear positioning templates open the mold, and the product can be removed. For products with symmetrical shapes, the above operation can be repeated to complete the pressing and edging operation on the other end face. In this embodiment, the edging mold 3 has two sets of positioning cavities, that is, it can press and edge two products at a time, and of course, it can be expanded as needed.

[0024] This invention utilizes the aforementioned equipment, employing a servo motor and reducer to drive the lead screw and pressing assembly for pressing action. This achieves a high-precision, high-thrust pressing effect, improving the accuracy of product pressing, especially for edge binding operations on EVA material main materials. Furthermore, this invention, in conjunction with an edge binding mold, can simultaneously perform pressing and edge binding operations on multiple products, thereby increasing efficiency.

[0025] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
