Description

Technical Field

[0001] The utility model relates to the technical field of spectacle case processing, and specifically, to a processing device for the shell material of a spectacle case. Background Art

[0002] In essence, a spectacle case is a box for holding glasses. The existing shell materials of spectacle cases are usually composite materials, which are composed of five layers of leather material, glue film, EVA, glue film, and fabric laminated in sequence. When processing such composite materials, workers usually manually cover and laminate the five materials in sequence. During the lamination process, the edges of each layer must be aligned. Otherwise, waste will be generated. Moreover, during the lamination process, it is also necessary to avoid blisters and protrusions between two layers. After perfect alignment, fixing parts are nailed at both ends and then taken for processing into spectacle cases. The process is very troublesome and inefficient. Content of the Utility Model

[0003] In summary, to overcome the deficiencies of the prior art, the utility model provides a processing device for the shell material of a spectacle case with high efficiency.

[0004] To achieve the above object, the utility model provides the following technical solution: A processing device for the shell material of a spectacle case, including a frame body, a feeding mechanism, a connecting mechanism, and a cutting mechanism. The feeding mechanism, the connecting mechanism, and the cutting mechanism are arranged in sequence on the frame body. The feeding mechanism includes a conveyor belt, a first feeding roller, a second feeding roller, a third feeding roller, a fourth feeding roller, and a limiting member. The first feeding roller and the second feeding roller are located above the conveyor belt. The third feeding roller and the fourth feeding roller are located below the conveyor belt. The limiting member is located on one side of the conveyor belt facing the connecting mechanism. A gap is provided between the limiting member and the conveyor belt. The connecting mechanism includes a connecting component and two pressing rollers. The connecting component is located on the side of the pressing rollers facing the cutting mechanism. The connecting component connects multiple layers of materials. The cutting mechanism cuts the multiple layers of materials.

[0005] With such a setting, when in use, first place the leather material and a film on the first feeding roller and the second feeding roller respectively, and then place the other film and the fabric on the third feeding roller and the fourth feeding roller, or vice versa. The EVA materials are stacked on the conveyor belt in multiple layers. When processing is required, start the equipment, and the conveyor belt starts to operate, sending the EVA materials on the conveyor belt to the position between the two pressing rollers of the connecting mechanism. Since the path is limited by the limiting member, only one piece can pass through at a time. In this way, only one piece will move towards the pressing roller. After one piece of EVA passes through the limiting member, the second piece will fall onto the conveyor belt and be driven by it again. The second piece will push the first piece to continue moving. At the same time, the leather material, the two films, and the fabric on each feeding roller will also be sent to this position and are successively laminated on the EVA material and passed through the pressing rollers to be pressed by them. When the head of the material just enters, the connecting component will make a connection to it once, fixing one end of it. After one piece of material completely passes through the pressing rollers, the connecting component will make a second connection to its tail, fixing both ends of it. Then it is continuously pushed to the position of the cutting mechanism to be cut, disconnecting the leather material, the film, and the fabric and trimming the edges. In this way, the processing of a composite material is completed. Except for loading the materials, the process is automatic, without the need for manual operations such as aligning, laminating, and connecting the materials, and the efficiency is higher.

[0006] Further, the feeding mechanism further includes a pressing component, and the pressing component applies a force towards the conveyor belt direction.

[0007] With such a setting, the pressing component will continuously apply pressure to the stacked EVA sheets on the conveyor belt, enabling them to tightly adhere to the conveyor belt and be driven by the frictional force of the conveyor belt, and will not bounce during the conveying process, resulting in the inability to continue pushing.

[0008] Further, the pressing component includes a first cylinder and a pressing plate. The frame body is provided with a pressing frame at the position of the conveyor belt. The first cylinder is connected to the pressing frame. The first cylinder is arranged towards the conveyor belt direction. The pressing plate is connected to the output head of the first cylinder, and the pressing plate is located above the conveyor belt.

[0009] With such a setting, when in use, the first cylinder will press down the pressing plate at the output head position, and the pressing plate will press on the EVA sheet to apply pressure to it. Using a cylinder as the pressing device, the output force is small, it is easier to control, and it is not easy to cause the situation that the conveyor belt cannot drag the EVA sheet due to excessive pressure.

[0010] Further, the frame body is provided with two tensioning rollers. One of the tensioning rollers is located between the first feeding roller and the second feeding roller and the pressing roller, and the other tensioning roller is located between the third feeding roller and the fourth feeding roller and the pressing roller.

[0011] With such arrangement, the tensioning roller can tension the upper leather material, the rubber film and the lower rubber film and the cloth, thereby reducing the possibility of bubbling when they are pressed together and increasing the quality of the finished product.

[0012] Furthermore, the frame is provided with guide plates at a position between the feeding mechanism and the connecting mechanism and at a position between the connecting mechanism and the cutting mechanism.

[0013] With such arrangement, the guide plate can guide the EVA sheet, making it easier for the EVA sheet to enter between the two pressing rollers and the cutting mechanism.

[0014] Furthermore, the connecting mechanism also includes a pressing plate and a rotating rod, the rotating rod passes through the pressing plate, the rotating rod is located on the side of the clamping roller facing the feeding mechanism, the pressing plate is located above the guide plate, and a raised head is provided on the end of the pressing plate facing the feeding mechanism.

[0015] With such arrangement, the pressing sheet can be put on the rotating rod when installed, so that it can swing on the rotating rod. When the EVA sheet has not passed through, the pressing sheet will fall on the guide plate at this position, and when the EVA sheet passes through, it will first hit the position of the lifting head, and lift the pressing sheet against the bottom of the lifting head. The pressing sheet will then be pressed on the EVA sheet to prevent it from lifting before entering the clamping roller.

[0016] Furthermore, the connecting assembly includes a second cylinder and a heat sealing head, the heat sealing head is connected to the output head of the second cylinder, and two of the second cylinder and the heat sealing head are provided, and the two second cylinders are arranged opposite to each other above and below the side of the clamping roller facing the cutting mechanism.

[0017] With this arrangement, after the five layers of material are initially pressed together by the two pressing rollers, they will move to the position of the heat sealing head. At this time, the second cylinder will drive the heat sealing head to press toward the composite material. The upper and lower heat sealing heads will clamp and heat the composite material to heat seal it. After the heat sealing is completed, the composite material will continue to be pushed until its tail end reaches the position of the heat sealing head again and is clamped and heat sealed by it again. The structure is simple and the heat sealing connection effect is better.

[0018] Furthermore, the cutting mechanism includes a cutting table, a cutting frame, a cutting knife, an eccentric wheel and a driving motor, the cutting frame is slidably connected to the cutting table at one end facing away from the connecting mechanism, the sliding direction of the cutting frame is vertically arranged toward the top surface of the cutting frame, the cutting knife is connected to the cutting frame at a position above the cutting table, the cutting frame is provided with two driving rods, the spacing between the two driving rods is adapted to the outer diameter of the eccentric wheel, and the eccentric wheel is connected to the output head of the driving motor.

[0019] With such arrangement, when the heat-sealed composite material is moved to the cutting table, it will be pushed to its end. When the position to be cut moves to the end, the driving motor will operate to drive the eccentric wheel at the output head position to rotate, so that the eccentric wheel will rotate between the two driving rods. Since its rotation center is eccentrically set, it will push the two driving rods to rise or fall during the rotation process. When shearing, it will be lowered first, and the cutting knife on the top will descend toward the end of the cutting table to cut the composite material. After shearing, it will rise again, and then the composite material sheet after cutting will continue to be pushed for unloading. The structure is simple and the cutting force is strong.

[0020] Furthermore, the cutting table is provided with a sliding limit plate with an L-shaped cross-section at one end facing away from the connecting mechanism. Two sliding limit plates are provided. The two sliding limit plates are arranged opposite to each other on the cutting table, and the cutting frame is adapted between the two sliding limit plates.

[0021] With such arrangement, the two sliding limit plates will buckle the cutting frame, so that the cutting frame can slide between the two, the structure is simple, and the sliding process is stable.

[0022] Furthermore, a guide frame is provided on the side of the top surface of the cutting table facing away from the connecting mechanism, and a top plate of the guide frame is tilted toward one side of the connecting mechanism.

[0023] In this way, the guide frame will establish a shrinkage area at the end of the cutting table to prevent the composite material from warping at the cutting position. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] This specific embodiment is only an explanation of this embodiment, and it is not a limitation of this embodiment. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of this embodiment, they are protected by the patent law.

[0031] Referring to the attached drawings, the present invention provides the following technical solution: A processing device for spectacle case shell materials, including a frame body 1, a feeding mechanism 2, a connecting mechanism 3 and a cutting mechanism 4. The feeding mechanism 2, the connecting mechanism 3 and the cutting mechanism 4 are arranged in sequence on the frame body 1. The feeding mechanism 2 includes a conveyor belt 201, a first feeding roller 202, a second feeding roller 203, a third feeding roller 204, a fourth feeding roller 205 and a limiting member 206. The first feeding roller 202 and the second feeding roller 203 are located above the conveyor belt 201. The third feeding roller 204 and the fourth feeding roller 205 are located below the conveyor belt 201. The limiting member 206 is located on the side of the conveyor belt 201 facing the connecting mechanism 3. There is a gap between the limiting member 206 and the conveyor belt 201. The connecting mechanism 3 includes a connecting component 301 and two pressing rollers 302. The connecting component 301 is located on the side of the pressing rollers 302 facing the cutting mechanism 4. The connecting component 301 connects multiple layers of materials. The cutting mechanism 4 cuts multiple layers of materials. The above settings are not limited. The number of feeding rollers can also be increased or decreased and their positions can be changed according to actual needs. A baffle can also be provided on the side of the conveyor belt 201 to limit the width direction of the EVA sheet, and a structure with adjustable position can also be added to adapt to different sizes. If the connecting mechanism 3 is set as a movable structure, a connecting frame can also be added as an outer shell, and the structures in the connecting mechanism 3 are all connected to the connecting frame.

[0032] Set up like this. When in use, first place the leather material and a film on the first feeding roller 202 and the second feeding roller 203 respectively, then place the other film and the fabric on the third feeding roller 204 and the fourth feeding roller 205, or vice versa. The EVA materials are stacked on the conveyor belt 201. When processing is required, start the equipment, and the conveyor belt 201 starts to operate, sending the EVA materials on the conveyor belt 201 to the position between the two pressing rollers 302 of the connecting mechanism 3. Due to being limited by the limiting member 206 on the path, only one piece can pass through at a time. In this way, only one piece will move towards the pressing roller 302. After one piece of EVA passes through the limiting member 206, the second piece will fall onto the conveyor belt 201 and be driven by it again. The second piece will push the first piece to continue moving. At the same time, the leather material, the two films and the fabric on each feeding roller will also be sent to this position and are successively laminated on the EVA material and pass through the pressing roller 302 and are pressed by it. When the head of the material just enters, the connecting component 301 will make a connection to it once, fixing one end of it. After one piece of material completely passes through the pressing roller 302, the connecting component 301 will make a second connection to its tail, fixing both ends of it. Then it is continuously pushed to the position of the cutting mechanism 4 and is cut by it, disconnecting the leather material, the film and the fabric and trimming the edges. In this way, the processing of a composite material is completed. Except for loading materials, it is all automatic, without the need for manual operations such as aligning, laminating, and connecting materials, and the efficiency is higher.

[0033] Preferably in this embodiment, the feeding mechanism 2 further includes a pressing component 207, and the pressing component 207 applies a force towards the conveyor belt 201.

[0034] Set up like this, the pressing component 207 will continuously apply pressure to the stacked EVA sheets on the conveyor belt 201, enabling them to tightly adhere to the conveyor belt 201 and be driven by the frictional force of the conveyor belt 201, and will not bounce during the conveying process and cause inability to continue pushing.

[0035] Preferably in this embodiment, the pressing component 207 includes a first air cylinder 2071 and a pressing plate 2072. The frame 1 is provided with a pressing frame 101 at the position of the conveyor belt 201. The first air cylinder 2071 is connected to the pressing frame 101. The first air cylinder 2071 is arranged towards the conveyor belt 201. The pressing plate 2072 is connected to the output head of the first air cylinder 2071. The pressing plate 2072 is located above the conveyor belt 201. The above setting is not limited. The pressing component 207 can also use hydraulic, electric, heavy objects or other structures for pressing. Two first air cylinders 2071 and two pressing frames 101 can also be provided.

[0036] With such an arrangement, when in use, the first cylinder 2071 will press down the pressure plate 2072 at the output head position, and the pressure plate 2072 will press on the EVA sheet to apply pressure thereto. By using a cylinder as a pressurizing device, the output force is small and easier to control, and it is not easy for the conveyor belt 201 to be unable to drag the EVA sheet due to excessive pressure.

[0037] In the present embodiment, the frame 1 is preferably provided with two tensioning rollers 102, one of which is located between the first feed roller 202, the second feed roller 203 and the pressure roller 302, and the other is located between the third feed roller 204, the fourth feed roller 205 and the pressure roller 302. The above setting is not limiting, and the number of tensioning rollers 102 can be adjusted according to the distance between each feed roller and the pressure roller 302, and can be set to one, three or more. A tensioning roller 102 that can play a guiding role can also be added, and conical discs are set on both sides of the tensioning roller to guide it axially while tensioning.

[0038] With such arrangement, the tensioning roller 102 can tension the leather material and the rubber film above and the rubber film and the cloth below, thereby reducing the possibility of bubbling when they are pressed together and increasing the quality of the finished product.

[0039] Preferably, in this embodiment, the frame 1 is provided with guide plates 103 at a position between the feeding mechanism 2 and the connecting mechanism 3 and at a position between the connecting mechanism 3 and the cutting mechanism 4. The above setting is not limiting, and a limit plate may be further provided on the guide plate 103 to limit the height and width of the composite material.

[0040] With such arrangement, the guide plate 103 can guide the EVA sheet, making it easier for it to enter between the two pressing rollers 302 and the cutting mechanism 4 .

[0041] Preferably, in this embodiment, the connecting mechanism 3 also includes a pressing plate 303 and a rotating rod 304. The rotating rod 304 is arranged to pass through the pressing plate 303. The rotating rod 304 is located on the side of the clamping roller 302 facing the feeding mechanism 2. The pressing plate 303 is located above the guide plate 103. The end of the pressing plate 303 facing the feeding mechanism 2 is provided with a tilting head 3031.

[0042] With such arrangement, the pressing sheet 303 can be mounted on the rotating rod 304 during installation, so that it can swing on the rotating rod 304. When the EVA sheet has not passed through, the pressing sheet 303 will fall on the guide plate 103 at this position, and when the EVA sheet passes through, it will first hit the position of the lifting head 3031, and lift the pressing sheet 303 against the bottom of the lifting head 3031. The pressing sheet 303 will then be pressed on the EVA sheet to prevent it from lifting before entering the clamping roller 302.

[0043] Preferably in this embodiment, the connecting assembly 301 includes a second cylinder 3011 and a heat-sealing press head 3012. The heat-sealing press head 3012 is connected to the output head of the second cylinder 3011. There are two second cylinders 3011 and two heat-sealing press heads 3012. The two second cylinders 3011 are oppositely arranged above and below the side of the pressing roller 302 facing the cutting mechanism 4. The above setting is not a limitation. Only one set of the second cylinder 3011 and the heat-sealing press head 3012 can also be provided and clamped by one cylinder. The connecting assembly 301 can also use a binding machine to staple the two ends of the composite material. The cylinder can also be replaced by equipment such as a hydraulic cylinder or a motor.

[0044] With such a setting, after the five-layer material is preliminarily pressed by the two pressing rollers 302, it will move to the position of the heat-sealing press head 3012. At this time, the second cylinder 3011 will drive the heat-sealing press head 3012 to press towards the composite material. The upper and lower heat-sealing press heads 3012 will clamp and heat the composite material and perform heat-sealing treatment on it. After the heat-sealing is completed, the composite material continues to be pushed until its tail comes to the position of the heat-sealing press head 3012 again and is clamped and heat-sealed again. The structure is simple and the heat-sealing connection effect is better.

[0045] Preferably in this embodiment, the cutting mechanism 4 includes a cutting table 401, a cutting frame 402, a cutting knife 403, an eccentric wheel 404, and a driving motor 405. The cutting frame 402 is slidably connected to one end of the cutting table 401 facing away from the connecting mechanism 3. The sliding direction of the cutting frame 402 is perpendicular to the top surface of the cutting frame 402. The cutting knife 403 is connected to the cutting frame 402 at a position above the cutting table 401. The cutting frame 402 is provided with two driving rods 4021. The distance between the two driving rods 4021 is adapted to the outer diameter of the eccentric wheel 404. The eccentric wheel 404 is connected to the output head of the driving motor 405. The above setting is not a limitation. The cutting mechanism 4 can also adopt a structure of directly shearing with a cylinder and a blade or other structures.

[0046] With such a setting, after the heat-sealed composite material moves onto the cutting table 402, it will be pushed towards its end. When the position to be cut moves to the end, the driving motor 405 will operate, driving the eccentric wheel 404 at the position of its output head to rotate. In this way, the eccentric wheel 404 will rotate between the two driving rods 4021. Since its rotation center is eccentrically arranged, it will push the two driving rods 4021 to rise or fall during the rotation process. When cutting, it will first descend, and the cutting knife 403 at its top will descend towards the end of the cutting table 401 to cut the composite material. After cutting, it will rise again. Then the cut composite material sheet will be continuously pushed for blanking. The structure is simple and the cutting force is strong.

[0047] Preferably, at one end of the cutting table 401 facing away from the connecting mechanism 3, there are sliding limit plates 4011 with an L-shaped cross-section. There are two sliding limit plates 4011, and the two sliding limit plates 4011 are oppositely arranged on the cutting table 401. The cutting frame 402 is adapted between the two sliding limit plates 4011.

[0048] With this arrangement, the two sliding limit plates 4011 will hold the cutting frame 402 and enable it to slide between them. The structure is simple and the sliding process is stable.

[0049] Preferably, on one side of the top surface of the cutting table 401 facing away from the connecting mechanism 3, there is a guiding frame 4012. The top plate of the guiding frame 4012 is tilted upward on the side facing the connecting mechanism 3.

[0050] With this arrangement, the guiding frame 4012 will create a constriction area at the end of the cutting table 401 to prevent the composite material from warping at the cutting position.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
