Description

Technical Field

[0001] The present invention relates to the technical field of hot pressing composite processing, and in particular, to a hot pressing composite punching processing device. Background Art

[0002] As an important processing method, the hot pressing composite process is widely used in the composite processing scenarios of fabrics and plastic skeletons. Through the hot pressing method, the plastic skeleton can be firmly compounded on the fabric, thereby forming products with specific functions and structures, which are significantly applied in many industries such as clothing, luggage, and automotive interiors.

[0003] However, there are certain technical bottlenecks in the existing hot pressing composite process. In the actual processing, multiple plastic skeletons are usually compounded on a single fabric. After hot pressing, these multiple products are connected together. At this time, in order to obtain individual products, manual fabric cutting is required to separate the multiple products. This manual cutting method has many disadvantages. On the one hand, the efficiency of manual operation is low, and a large amount of labor and time costs are required, making it difficult to meet the efficiency requirements of large-scale industrial production. In the current increasingly competitive market, the low production efficiency will seriously affect the production capacity and economic benefits of enterprises. On the other hand, there is a risk of cutting damage in manual cutting. Due to the subjectivity and instability of manual operation, during the cutting process, the operator may, due to inaccurate grasp of the cutting size and shape, or improper control of factors such as the force and angle during operation, cause damage to the fabric or product, resulting in waste of raw materials and a decline in product quality. In addition, with the continuous improvement of market requirements for product quality, this method relying on manual cutting is increasingly difficult to meet the needs of high-quality production, and there is an urgent need for an improved device that can improve production efficiency and reduce the risk of damage. Summary of the Invention

[0004] The purpose of the present application is to provide a hot pressing composite punching processing device, which has the advantages of improving production efficiency and reducing the risk of damage in manual cutting.

[0006] Compared with the prior art, a hot-pressing composite punching and cutting processing device of the present application has the following advantages: Through the integrated design of the punching and cutting device and the extrusion forming device, fabric blanking is synchronously completed in the hot-pressing composite process, replacing the manual separation step, realizing integrated processing of composite and punching and cutting, and directly outputting independent finished products, thereby improving efficiency and reducing the risk of breakage.

[0007] In a possible implementation manner, two pressing blocks for cooperating with the punching and cutting base are arranged on the tool holder, a gap for the punching and cutting blade to pass through is formed between the two pressing blocks, and when the two pressing blocks and the punching and cutting base cooperate to squeeze the fabric together, the gap communicates with the punching and cutting groove. Compared with the prior art, the cooperation and extrusion of the pressing block and the punching and cutting base keep the fabric in a flat state, and the punching and cutting blade can accurately cut, improving the notch quality.

[0008] In a possible implementation manner, the punching and cutting base includes a fixed seat plate, a lifting plate, a lifting cylinder and a resisting block, the fixed seat plate is fixed on the lower die carrier, the lifting plate is connected to the fixed seat plate in a lifting manner through the lifting cylinder, the resisting block is fixed on the lifting plate and is used for cooperating with the pressing block, and the punching and cutting groove is opened on the top surface of the resisting block. Compared with the prior art, the height adjustability of the punching and cutting base is realized, the accuracy and quality of punching and cutting are ensured, and burrs and deformation at the edge of the fabric are reduced.

[0009] In a possible implementation, the heating device includes a moving bracket, a moving driver, and a heating source. The heating source is installed at the bottom of the moving bracket. The moving bracket is movably connected to the lower die carrier along the front-back direction by the moving driver. The lower die core is located below the moving path of the moving bracket. Compared with the prior art, the automatic movement of the heating device is realized, and the heating efficiency is improved. The heating source can be accurately positioned above the lower die core to ensure heating uniformity. The design of the moving bracket enables the heating device to withdraw from the working area when not in use, avoiding interference with other processes and improving the space utilization rate and overall working efficiency of the equipment.

[0010] In a possible implementation, the heating source includes several groups of composite infrared lamp tubes controlled by power supplies. The shape of the composite infrared lamp tubes matches the forming surface of the lower die core. Compared with the prior art, the processing quality and efficiency of the hot pressing composite process are improved, and product defects caused by uneven heating are reduced, thereby enhancing the overall quality of the product.

[0011] In a possible implementation, a limiting portion for limiting the moving bracket is provided on the lower die carrier. When the moving bracket abuts against the limiting portion, the heating source is directly opposite to the lower die core. Compared with the prior art, the accurate alignment of the heating source and the lower die core is realized. The setting of the limiting portion avoids the deviation of the position of the heating source, ensuring the accuracy and consistency of the heating process. This mechanical positioning method is simple and reliable, reducing the need for a complex electronic control system and lowering the failure rate of the equipment. At the same time, the precise positioning also improves the heating efficiency, reduces energy waste, and is beneficial to improving product quality and production efficiency.

[0012] In a possible implementation, a placement plate is provided at the top of the moving bracket. The placement plate is used for temporarily placing the fabric to be processed, and cooperating with the grasping device to realize the orderly feeding of the fabric. Compared with the prior art, the temporary storage and orderly feeding of the fabric are realized. The placement plate provides a stable temporary placement platform for the fabric. The cooperation with the grasping device ensures that the fabric can be accurately grasped and fed into the processing area in accordance with the predetermined order and position, improving the accuracy and efficiency of feeding. In addition, the setting of the placement plate also optimizes the working process of the operator, making the placement and grasping process of the fabric smoother and reducing the possibility of operation errors.

[0013] In a possible implementation, the grasping device includes two groups of grasping mechanisms for grasping the edges of the fabric. The two groups of grasping mechanisms are symmetrically arranged on the left and right sides of the upper die carrier respectively. The grasping ends of the grasping mechanisms are lower than the forming bottom surface of the upper die core. The distance between the two groups of grasping mechanisms is adjustable, so that the tension of the fabric can be adjusted, which is beneficial to fitting the die core. Compared with the prior art, the risk of punching and breaking caused by fabric positioning deviation is significantly reduced by automatic control instead of manual adjustment.

[0014] In a possible implementation, the grasping mechanism includes a mounting frame, an upper clamping block, a lower clamping block, a clamping rod, and a clamping cylinder. The mounting frame is arranged on the upper die holder. The upper clamping block is fixed to the mounting frame. The lower clamping block is fixed to the front end of the clamping rod. The lower clamping block and the upper clamping block are arranged opposite to each other. The middle of the clamping rod is hinged to the mounting frame, and the rear end of the clamping rod is hinged to the output end of the clamping cylinder. The clamping cylinder is mounted on the mounting frame and is used to swing the clamping rod so that the lower clamping block and the upper clamping block cooperate to grasp the edge of the fabric. Compared with the prior art, through the combination of rigid connection and hinge, while simplifying the driving structure, the repeated accuracy of fabric positioning is ensured, providing a stable basis for subsequent hot pressing and punching processes.

[0015] In a possible implementation, the grasping device further includes a transverse moving frame and a transverse moving driver. The transverse moving frame is connected to the upper die holder in a horizontally movable manner through the transverse moving driver, and the mounting frame is fixed to the transverse moving frame. Compared with the prior art, the automatic control of the horizontal position of the grasping device is realized, enabling the clamping point of the fabric edge to be adaptively adjusted according to the product specifications, ensuring that the fabric always maintains a uniform tightness state during the transfer process, avoiding wrinkles or slippage caused by clamping deviation, and significantly improving the yield rate of the hot pressing and composite process.

[0017] First of all, those skilled in the art should understand that these implementation manners are only used to explain the technical principles of the embodiments of the present application, and are not intended to limit the protection scope of the embodiments of the present application. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.

[0018] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0019] In the embodiments of the present application, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the first feature has a lower horizontal height than the second feature.

[0020] In the traditional existing hot-pressing composite processing process, after the plastic skeleton and the fabric are combined by the hot-pressing process, since multiple composite products are still connected to the same piece of fabric, manual cutting and separation are required. There is a contradiction between the cutting efficiency and the finished product yield in this operation: manual cutting cannot synchronously match the processing rhythm of the hot-pressing process, resulting in a decrease in the overall throughput of the production line; at the same time, the shear stress distribution of the fabric during the cutting process is uneven, and tears or burrs are likely to occur at the hot-melt adhesive bonding boundary, resulting in an increase in the product rejection rate.

[0021] If the above problems are not solved, the production rhythm of the hot pressing and composite process will be limited by the manual cutting speed for a long time, and full-process automation cannot be achieved. At the same time, the quality fluctuations caused by the burr defects will increase the screening costs in the product inspection process and reduce the trust of end customers in the product size accuracy, directly affecting the qualified rate of order delivery.

[0022] The following further describes the present application in detail with reference to the drawings and specific embodiments.

[0023] See Figures 1 to 9 , an embodiment of the present application discloses a hot pressing, composite, punching and cutting processing device, including a frame 1, an extrusion forming device 2, a heating device 3, a grasping device 4 and a punching and cutting device 5.

[0024] The frame 1 serves as the support structure of the entire hot pressing, composite, punching and cutting processing device. It can be welded or bolt-assembled with metal materials into a rigid frame, having sufficient strength and rigidity to withstand various forces and vibrations generated during the processing. A leveling device is provided at the bottom of the frame 1, which can be adjusted according to the ground conditions to ensure that the entire device is placed horizontally. A forklift slot 11 is also provided at the bottom of the frame 1 to facilitate the movement and transportation of the overall device.

[0025] Continue to refer to Figure 2 , the extrusion forming device 2 includes an upper die holder 21, a lower die holder 22 and a die holder driving source; the upper die holder 21 is connected to the frame 1 in a lifting manner through the die holder driving source. The die holder driving source can adopt a hydraulic cylinder, which can provide sufficient pressure to make the upper die holder 21 descend smoothly and extrude and form the material; two upper die cores 211 are arranged at intervals left and right on the upper die holder 21. The upper die cores 211 are made of high-strength alloy materials, and the surfaces are hardened, having good wear resistance and heat resistance; the lower die holder 22 is fixedly connected to the frame 1 and is located below the upper die holder 21. A lower die core 221 corresponding to and matching the upper die core 211 is provided on the lower die holder 22. The lower die core 221 can also be made of high-strength alloy materials, and the surface is also hardened; a positioning groove is provided on the lower die core 221 for the placement and fixation of the plastic skeleton to ensure that the plastic skeleton will not be displaced during the processing. Cooling devices are provided inside the upper die core 211 and the lower die core 221 for cooling the products after hot pressing and composite.

[0026] Continue to refer to Figure 8 and Figure 9, the heating device 3 is installed on the lower mold base 22 and is used to heat and activate the hot melt adhesive layer on the plastic skeleton. The heating device 3 includes a moving bracket 31, a moving driver, and a heat source 32; the heat source 32 is installed at the bottom of the moving bracket 31, and the moving bracket 31 is movably connected to the lower mold base 22 in the front-rear direction through the moving driver; the moving driver can adopt a servo motor combined with a lead screw transmission mechanism, which can achieve precise positioning and stable movement of the heating device 3; the lower mold core 221 is located below the moving path of the moving bracket 31. When the heating device 3 moves to the working position, the heat source 32 is directly opposite the lower mold core 221, and the plastic skeleton placed on the lower mold core 221 can be heated. Specifically, when it is necessary to heat the plastic skeleton, the moving driver pushes the moving bracket 31 to move forward along a predetermined path until the heat source 32 reaches directly above the lower mold core 221; at this time, the heat energy emitted by the heat source 32 directly acts on the plastic skeleton on the surface of the lower mold core 221 to activate its hot melt adhesive layer; after the heating is completed, the moving driver drives the moving bracket 31 to move backward and reset to make room for the subsequent punching process; through the directional movement of the moving bracket 31, the heating process is only started when the lower mold core 221 needs to be heated, reducing heat energy loss and improving heating efficiency.

[0027] The heat source 32 includes several groups of power-controlled composite infrared lamp tubes. The shape of the composite infrared lamp tubes matches the forming surface of the lower mold core 221 to ensure that the heat can be evenly distributed on the surface of the plastic skeleton; the power of the composite infrared lamp tubes is adjustable and the temperature is controllable, and the hot melt adhesive layer can be heated to the molten state in a short time.

[0028] The lower mold base 22 is provided with a limiting portion 222 for limiting the moving bracket 31. When the moving bracket 31 abuts against the limiting portion 222, the heat source 32 is directly opposite the lower mold core 221; the position of the limiting portion 222 can be finely adjusted according to actual needs to ensure that the heat source 32 can be accurately positioned at the optimal heating position. Specifically, when the moving driver drives the moving bracket 31 to move in the front-rear direction, the moving range of the moving bracket 31 is determined by the position of the limiting portion 222; when the moving bracket 31 reaches the position of the limiting portion 222, the two abut against each other to form a hard limit. At this time, the heat source 32 of the moving bracket 31 is exactly located directly above the lower mold core 221; during this process, the physical blocking effect of the limiting portion 222 eliminates the displacement deviation caused by the stroke error or mechanical clearance of the moving driver, ensuring that the spatial position of the heat source 32 and the lower mold core 221 strictly corresponds; the precise alignment of the heat source 32 with the lower mold core 221 enables the hot melt adhesive layer on the plastic skeleton to be evenly heated and activated, avoiding local overheating or insufficient heating caused by position deviation.

[0029] The top of the moving support 31 is provided with a placement plate 311, which is used to temporarily place the fabric to be processed, and cooperate with the grasping device 4 to achieve orderly feeding of the fabric; the placement plate 311 can be made of smooth stainless steel plate, and its surface is polished to reduce the friction between the fabric and the placement plate 311, facilitating the movement and grasping of the fabric. Specifically, when the moving support 31 moves to directly above the lower die insert 221, the placement plate 311 is in a stationary state. At this time, the fabric to be processed is pre-laid on the surface of the placement plate 311 manually or by a robotic arm; the placement plate 311 serves as an intermediate transition platform, preventing the fabric from directly piling up in the heating area or other positions of the frame 1, ensuring that the fabric position is fixed during each feeding, and reducing the positioning error of the grasping mechanism 41 caused by fabric offset; through the coordinated cooperation of the placement plate 311 and the grasping device 4, the fabric is always in a controlled state during the transfer process, effectively reducing the frequency of manual intervention and improving the processing continuity.

[0030] Continue to participate Figure 7 , the grasping device 4 is installed on the upper die holder 21 and is used to transfer the fabric between the upper die insert 211 and the lower die insert 221. The grasping device 4 includes two sets of grasping mechanisms 41 for grasping the edges of the fabric, and the two sets of grasping mechanisms 41 are symmetrically arranged on the left and right sides of the upper die holder 21 respectively; the grasping end of the grasping mechanism 41 is lower than the forming bottom surface of the upper die insert 211 to ensure that it will not interfere with the upper die insert 211 when grasping the fabric.

[0031] The grasping mechanism 41 includes a mounting bracket 411, an upper clamping block 412, a lower clamping block 413, a clamping rod 414 and a clamping cylinder 415; the mounting bracket 411 is arranged on the upper die holder 21, the upper clamping block 412 is fixed on the mounting bracket 411, the lower clamping block 413 is fixed at the front end of the clamping rod 414, and the lower clamping block 413 and the upper clamping block 412 are arranged opposite to each other; the middle of the clamping rod 414 is hinged on the mounting bracket 411, the rear end of the clamping rod 414 is hinged on the output end of the clamping cylinder 415, and the clamping cylinder 415 is installed on the mounting bracket 411 and is used to swing the clamping rod 414 to make the lower clamping block 413 and the upper clamping block 412 cooperate to grasp the edge of the fabric. The clamping cylinder 415 can provide sufficient clamping force to ensure that the fabric will not fall off during the movement. Specifically, when the fabric is placed on the placement plate 311 at the top of the moving support 31, the grasping device 4 is driven by the upper die holder 21 to move downward, and then the clamping cylinder 415 is activated to push the rear end of the clamping rod 414, and the clamping rod 414 swings around the hinge point, and the lower clamping block 413 and the upper clamping block 412 close to clamp the two edges of the fabric.

[0032] The distance adjustment between the two sets of grasping mechanisms 41 enables the adjustment of the tension of the fabric, which is beneficial for conforming to the mold core. That is, the grasping device 4 further includes a transverse moving frame 42 and a transverse moving driver 43. The transverse moving frame 42 is connected to the upper mold base 21 so as to move in the left-right direction through the transverse moving driver 43, and the mounting frame 411 is fixed on the transverse moving frame 42. Specifically, the transverse moving driver 43 drives the transverse moving frame 42 to move transversely along the guiding tracks on both sides of the upper mold base 21, driving the mounting frame 411 and the grasping mechanism 41 thereon to move synchronously. The two sets of grasping mechanisms 41 respectively adjust their left and right positions through independently controlled transverse moving drivers 43, so that the distance between the clamping points at the edge of the fabric matches the width of the mold core. After clamping the fabric, the transverse moving driver 43 can further finely adjust the clamping distance, so that the fabric forms a moderately tight state on the surface of the mold core, ensuring the conforming stability with the mold core. The transverse moving driver 43 can be made of a cylinder.

[0033] Continue to participate Figure 5 and Figure 6 The punching device 5 includes a punching blade 51, a lifter 52, a tool holder 53 and a punching base 54. The tool holder 53 is fixed on the upper mold base 21 and is located between two adjacent upper mold cores 211. The punching blade 51 is connected to the tool holder 53 through the lifter 52 so as to move up and down. The lifter 52 can be driven by a cylinder and can provide sufficient punching force. The punching base 54 is connected to the lower mold base 22 and is arranged opposite to the punching blade 51. A punching groove 55 for the punching blade 51 to be embedded is provided on the punching base 54. The punching blade 51 is made of high-speed steel material, and the cutting edge has been specially heat-treated, with a hardness reaching above HRC60, having good cutting performance and durability. The cutting edge of the punching blade 51 has a serrated structure, improving the punching reliability of the blade.

[0034] Two pressing blocks 531 for cooperating with the punching base 54 are provided on the tool holder 53. A gap for the punching blade 51 to pass through is formed between the two pressing blocks 531. When the two pressing blocks 531 and the punching base 54 cooperate to squeeze the fabric together, the gap communicates with the punching groove 55. Among them, the two pressing blocks 531 are symmetrically arranged on both sides of the tool holder 53, and the width of the gap is slightly larger than the thickness of the punching blade 51, ensuring that the blade is not hindered when cutting vertically downward. The pressing blocks 531 can be made of high-temperature resistant polyurethane material, with a smooth surface, which can effectively fix the fabric, prevent the fabric from displacing during the punching process, and ensure the punching accuracy.

[0035] The punching base 54 includes a fixed base plate 541, a lifting plate 542, a lifting cylinder 543 and a pressing block 544; the fixed base plate 541 is fixed on the lower die holder 22, the lifting plate 542 is connected to the fixed base plate 541 in a liftable manner through the lifting cylinder 543, the pressing block 544 is fixed on the lifting plate 542 and is used to cooperate with the pressing block 531, and a punching groove 55 is formed on the top surface of the pressing block 544; the lifting cylinder 543 can provide sufficient supporting force to ensure that the punching base 54 will not sink during the punching process. Among them, the fixed base plate 541 is fixed on the lower die holder 22 by bolts or welding to form a stable supporting foundation; the lifting plate 542 is slidably connected to the fixed base plate 541 through a guide rail, and the end of the piston rod of the lifting cylinder 543 is connected to the bottom of the lifting plate 542. Specifically, when the punching blade 51 performs a cutting action, the lifting cylinder 543 drives the lifting plate 542 to move vertically, driving the pressing block 544 to contact the pressing block 531; at this time, the pressing block 544 and the pressing block 531 form a clamping area, and the fabric is pressed tightly between the two; when the punching blade 51 moves down along the gap, it accurately fits into the punching groove 55 to complete the cutting operation. The pressing block 544 can be made of aluminum alloy material and has good wear resistance.

[0036] The working process of the hot pressing and composite punching processing equipment is as follows: First, place the plastic skeleton on the lower die insert 221 and fix it through the positioning groove; then, the heating device 3 moves to the working position and places the fabric on the placement plate 311; the grasping device 4 grasps the fabric from the placement plate 311; then, the heating device 3 heats and activates the hot melt adhesive layer on the plastic skeleton; after the heating is completed, the heating device 3 moves out of the working area; the upper die holder 21 descends under the drive of the die holder drive source, and the upper die insert 211 and the lower die insert 221 are extrusion-fitted to perform hot pressing and composite on the fabric and the plastic skeleton; after the hot pressing and composite is completed, the punching device 5 performs punching processing on the composite product to separate adjacent products; finally, the upper die holder 21 rises and the processed product is taken out. The entire processing process has a high degree of automation, high production efficiency, and stable product quality. The hot pressing and composite and punching processing are completed on the same equipment, reducing the process transfer, lowering the production cost, improving the production efficiency, realizing the full-process automation of the hot pressing and composite process, and meeting the requirements of large-scale industrial production for efficiency and quality.
