[0001] The utility model relates to the technical field of easy-open lid production lines, in particular to a waste discharging net system for an easy-open lid basic lid punching machine. Background Art

[0002] In the easy-open lid basic lid production line, aluminum sheets are used as raw materials. After the coating process, the printing process, they are formed into basic lids through die stamping by a basic lid punching machine and then formed by a curling machine, and finally deformed into basic lid products. During this production process, the sheet material is die stamped by the die of the basic lid punching machine, forming waste material and waste net sheets.

[0003] In the prior art, the characteristics of this net sheet are that it is full of holes, the residual edge is very small, it is relatively soft, and has a light weight. Due to the light weight of the aluminum sheet itself and the even smaller mass of the waste net sheet, the waste net material often cannot be discharged at the position where it exits the punching machine and accumulates at the discharge port. This causes new net sheets not to come out, resulting in the production line stopping, seriously affecting the production efficiency of the easy-open lid line. Summary of the Utility Model

Specific embodiments

[0027] The following further elaborates on the present utility model in detail with reference to the accompanying drawings.

[0028] Embodiment:

[0029] Referring to Figure 1 - Figure 5 , a waste discharging net system for an easy - pull cover basic cover punching machine disclosed by the present utility model includes a platform plate 1, on the top of which two groups of mounting brackets 5 are symmetrically arranged. A roller 7 is connected between the two groups of mounting brackets 5 through a spherical roller bearing with housing 6;

[0030] The lower pressing rubber wheel assembly 2, which is composed of a fixed bracket 21, a cylinder 22 and a rubber wheel part 23. There are two fixed brackets 21, which are respectively arranged on the outer sides of the two mounting brackets 5. A rubber wheel part 23 located directly above the roller 7 is arranged between the two fixed brackets 21, and both ends of the rubber wheel part 23 are connected to the fixed brackets 21 through cylinders 22;

[0031] The motor 3, which is installed at the bottom of the platform plate 1 and is connected to the roller 7 through a synchronous belt 8;

[0032] The tensioning assembly 4, which is arranged on the top of the platform plate 1 and is used to tension the synchronous belt 8.

[0033] In this embodiment, since the residual edge of the waste mesh sheet generated in the stamping process of the easy-open lid is very small and the weight is light, the waste mesh sheet cannot be effectively discharged when it exits the punching press, causing the waste mesh sheet to accumulate at the discharge port, resulting in the production line being shut down and affecting the production efficiency of the easy-open lid.

[0034] Therefore, observing Figure 1 it can be found that an installation bracket 5 is provided on the top of the platform plate 1, and a roller 7 is connected between the installation brackets 5 through a spherical roller bearing with housing 6. Subsequently, a fixed bracket 21 is provided outside the installation bracket 5, and a rubber wheel member 23 is connected between the two fixed brackets 21 through a cylinder 22. When the waste mesh sheet is discharged, it is detected by a sensor located at the machine tool discharge port. Subsequently, the sensor sends a signal to make the cylinder 22 operate to push the rubber wheel member 23 downward, so that the rubber wheel member 23 cooperates with the roller 7 to press the waste mesh sheet tightly, enabling sufficient friction between the roller 7 and the waste mesh sheet. Thus, when the roller 7 is driven to rotate by the motor 3, the waste mesh sheet can be pushed out, avoiding the accumulation of the waste mesh sheet at the discharge port of the punching press, effectively ensuring the continuous operation stability of the machine tool, and thus improving the production efficiency of the easy-open lid.

[0035] While observing Figure 2 and Figure 5 it can be found that the motor 3 for driving the roller 7 to rotate is installed at the bottom of the platform plate 1, and the synchronous belt passes through the platform plate 1 through the relief hole on the platform plate 1 and is bent 90 degrees through the tensioning assembly 4 to be connected to the roller 7. This structure saves the space of the entire mechanism. The motor 3 below does not affect the mechanical structure of the upper plane, and the aluminum sheet conveying is not affected either.

[0036] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, the rubber wheel member 23 includes a rubber wheel shaft 231, a clamping sleeve 232, and a rubber wheel 233. Both ends of the rubber wheel shaft 231 are connected with a cylinder connection block 9, and the top of the cylinder connection block 9 is fixedly connected to the output shaft of the cylinder 22. A rubber wheel 233 is rotatably connected to the outer peripheral side of the rubber wheel shaft 231 through a bearing. Clamping sleeves 232 for positioning the rubber wheel 233 are provided at both ends of the rubber wheel 233, and the clamping sleeves 232 and the rubber wheel 233 are connected through a positioning pad 10;

[0037] The roller 7 is a hollow steel roller, and the rubber wheel 233 is made of polyurethane with a Shore hardness of 70-75.

[0038] In this embodiment, observing Figure 3It can be found that by connecting a rubber wheel 233 to the rubber wheel shaft 231, the rubber wheel 233 can be adjusted according to the position of the roller 7, so that the rubber wheel 233 can be located above the roller 7. When the rubber wheel 233 is pressed against the roller 7, the pressing surface is uniform. The light and soft waste mesh can obtain a high linear speed through the friction of the two rollers, and the waste mesh can be better fed into the waste basket.

[0039] Since the rubber wheel 233 needs to adjust its position on the rubber wheel shaft 231 according to the position of the roller 7, the rubber wheel 233 can slide on the rubber wheel shaft 231, which will make the rubber wheel 233 unstable and cause the rubber wheel 233 to deviate during long-term use. Therefore, the position of the rubber wheel 233 needs to be corrected frequently. Therefore, clamping sleeves 232 are provided at both ends of the rubber wheel 233. By using the clamping sleeves 232 to clamp the rubber wheel 233, the rubber wheel 233 can be prevented from shifting during long-term use, making the use of the rubber wheel 233 more stable.

[0040] By making the rubber wheel 233 made of polyurethane with a Shore hardness of 70-75, the rubber wheel 233 can better fit the waste mesh when pressing down on the waste mesh, increasing the friction during the transportation of the waste mesh, so that the waste mesh can be better pushed out of the discharge port of the punching machine. Figure 4 It can be found that the roller 7 is a hollow steel roller, which can effectively reduce the weight of the roller 7, thereby reducing the load on the motor 3 and further improving the energy efficiency of the motor 3.

[0041] In a further preferred embodiment of the present invention, as Figure 4 shown, the fixed bracket 21 is composed of an upper fixed seat 211 and a lower fixed seat 212. Among them, the lower fixed seat 212 is fixedly connected to the platform plate 1, the upper fixed seat 211 is fixedly connected to the top of the lower fixed seat 212, and a chute 11 is formed concave in the middle of the side where the upper fixed seat 211 contacts the lower fixed seat 212, and a slider 12 fixedly connected to the end of the rubber wheel shaft 231 is arranged in the chute 11.

[0042] In this embodiment, when the rubber wheel member 23 and the roller 7 transport the waste mesh, the rubber wheel member 23 will be pulled by the friction generated when the waste mesh moves, resulting in a tendency for the rubber wheel member 23 to move along with the waste mesh, causing the rubber wheel member 23 to exert a lateral force on the output shaft of the cylinder 22, affecting the force on the output shaft of the cylinder 22 and squeezing between the cylinder body of the cylinder 22, affecting the service life of the cylinder 22.

[0043] Therefore, observe Figure 4It can be found that the fixed bracket 21 is composed of an upper fixed seat 211 and a lower fixed seat 212. The lower fixed seat 212 is fixedly connected to the platform plate 1, and the upper fixed seat 211 is connected to the top of the lower fixed seat 212. Subsequently, a chute 11 is recessed in the middle of the side where the upper fixed seat 211 contacts the lower fixed seat 212, and a slider 12 fixedly connected to the end of the rubber wheel shaft 231 is arranged in the chute 11. This can make the rubber wheel member 23 move more stably when moving up and down under the operation of the air cylinder 22. Moreover, the slider 12 can also provide support for the rubber wheel member 23 when the rubber wheel member 23 is pulled, avoiding the swing of the air cylinder 22 and effectively extending the service life of the air cylinder.

[0044] In a further preferred embodiment of the present invention, as Figure 5 shown, the tensioning assembly 4 includes a belt pulley fixing seat 41, a flat belt pulley 42, and a synchronous belt pulley 43. A synchronous belt pulley 43 is rotatably connected to the top of the belt pulley fixing seat 41, and a flat belt pulley 42 is arranged obliquely below the synchronous belt pulley 43;

[0045] The synchronous belt pulley 43 meshes with the teeth inside the synchronous belt 8;

[0046] The flat belt pulley 42 is located on the side of the synchronous belt pulley 43 close to the roller 7, and the outer peripheral side of the flat belt pulley 42 contacts the outer side wall of the synchronous belt 8.

[0047] In this embodiment, it can be observed that Figure 5 by setting the belt pulley fixing seat 41 and connecting a synchronous belt pulley 43 inside the belt pulley fixing seat 41, the motor 3 located at the bottom of the platform plate 1 can be connected to the roller 7 located at the top of the platform plate 1 through the synchronous belt 8, so that when the motor 3 operates, it can drive the roller 7 to operate and push the waste mesh out of the discharge port of the punching machine.

[0048] Since the synchronous belt 8 needs to pass through the platform plate 1 to be connected to the roller 7, in order to ensure the transmission stability of the synchronous belt 8 and avoid the synchronous belt 8 affecting the transmission between the motor 3 and the roller 7 due to slack, a flat belt pulley 42 is also arranged on the belt pulley fixing seat 41. The flat belt pulley 42 is located on the side of the synchronous belt pulley 43 close to the roller 7, and the outer peripheral side of the flat belt pulley 42 contacts the outer side wall of the synchronous belt 8. This can make the synchronous belt 8 be supported by the flat belt pulley 42 and tightened, enabling the synchronous belt 8 to remain in a taut state during transmission and making the transmission between the motor 3 and the roller 7 more stable.

[0049] And it can also be observed that Figure 5 the motor 3 is connected to the platform plate 1 through the mounting plate, enabling the motor 3 to adjust its mounting position on the mounting plate, which can further tension the synchronous belt 8 and further ensure the stable transmission between the motor 3 and the roller 7.

[0050] In a further preferred embodiment of the present invention, asFigure 5 As shown, the mounting bracket 5 is mainly composed of a mounting base 51 and a cross bar 52. There are two mounting bases 51 arranged at intervals, and a cross bar 52 is fixedly connected between the two mounting bases 51. The spherical roller bearing 6 with housing is installed in the middle of the cross bar 52. On the outer wall of the mounting base 51 on the output side of the platform plate 1 and close to the roller 7, an anti-collision strip 53 is fixedly connected.

[0051] In this embodiment, by making the mounting bracket 5 composed of the mounting base 51 and the cross bar 52, with two mounting bases 51 arranged at intervals and a cross bar 52 fixedly connected between the two mounting bases 51, the support effect provided by the mounting base 51 to the cross bar 52 is better, so that the installation of the spherical roller bearing 6 with housing can be more stable, and the operation of the roller 7 can be more stable.

[0052] And by arranging an anti-collision strip 53 on the side of the mounting base 51 on the output side of the platform plate 1 and close to the roller 7, it is possible to prevent the mounting base 51 from colliding with and damaging the waste mesh when the roller 7 conveys the waste mesh, thereby protecting the mounting base 51 and increasing the service life of the mounting bracket 5.

[0053] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
