[0018] 1. This stamping and bending device adopts the design of storage components. Through the cooperation between the conveying belt and the pushing belt, the device can automatically convey materials when in use, thereby improving the working efficiency of the device. At the same time, since the surface of the pushing belt is higher than the design, the top surface of the pushing belt can be against the upper stamping plate to prevent the upper stamping plate from being tilted when the stamping plate at the bottom is pushed away, thereby affecting the normal transmission of the stamping plate and making the device more stable when in use.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1

[0034] like Figure 1 As shown, a stamping and bending machine for printer parts includes a device base 1, and a plurality of transmission wheels 11 for transmitting stamping plates are arranged on the upper end of the device base 1. A storage component 2 for storing stamping plates is arranged on the left side of the rear upper end of the device base 1. When the stamping plate to be used moves onto the transmission wheel 11, the transmission wheel 11 can transmit it to the stamping component 3, so that the stamping component 3 bends it. A stamping component 3 is also arranged on the right side of the upper end of the device base 1.

[0035] like Figure 2 and Figure 4 As shown, the storage assembly 2 includes a support frame 21 fixed to the upper end of the device base 1, and a conveyor belt 22 is commonly provided between the two vertical parts of the support frame 21. A single stamping plate required for use by the device when in use is located at the upper end of the conveyor belt 22. When the conveyor belt 22 is working (that is, when the conveyor belt 22 rotates), the stamping plate can be transported forward, so that the stamping plate is moved above the multiple transmission wheels 11. A push belt 23 is fixed to the outer surface of the conveyor belt 22, and the cross-sectional area of ​​the push belt 23 accounts for half of the cross-sectional area of ​​the conveyor belt 22 (such as Figure 3 and Figure 4As shown), when the conveyor belt 22 is working, the push belt 23 can push the stamping plate at the bottom to move forward. At the same time, since the surface of the push belt 23 is higher than the design of the conveyor belt 22, the top surface of the push belt 23 can be against the stamping plate above, preventing the stamping plate at the bottom from being pushed away. When a gap is generated above the conveyor belt 22, the stamping plate above will be tilted, thereby affecting the normal transmission of the stamping plate, making the device more stable when in use.

[0036] In addition, a storage frame 24 for storing the stamping plates is fixed to the upper end of the support frame 21, a cover plate 25 is fixed to the upper end of the storage frame 24, a plurality of springs 26 are fixed to the lower end of the cover plate 25, and a push plate 27 is fixed to one end of the two springs 26 away from the cover plate 25. Due to the design of the springs 26, the push plate 27 can push the stamping plates downward, so that the lowest stamping plate contacts the outer surface of the conveyor belt 22, which facilitates the conveyor belt 22 to transport the lowest stamping plate. A plurality of balls (not shown in the figure) can also be designed on the side of the outer surface of the push belt 23 away from the conveyor belt 22. , which can reduce the friction between the push belt 23 and the upper stamping plate (under the action of the stamping plate's own gravity and the elastic force of the spring 26, the friction between the lowest stamping plate and the push belt 23 becomes larger, which can easily cause a lot of wear on the push belt 23 after long-term use, shortening the service life of the device). A first motor 28 for driving the conveyor belt 22 is also provided at the upper end of the device base 1. When the first motor 28 is working, it can drive the conveyor belt 22 to rotate, and then through the mutual cooperation between the conveyor belt 22 and the push belt 23, the function of automatic material conveying is realized.

[0037] The specific implementation of this embodiment is as follows: when the device is used, the stamping plate to be used is first placed in the storage frame 24, and then the cover plate 25 is covered. Due to the design of the spring 26 and the push plate 27, the lowest stamping plate can be tightly fitted with the conveyor belt 22, which facilitates the conveyor belt 22 to transport the stamping plate. At this time, the notch of the push belt 23 is located behind the lowest stamping plate (such as Figure 3 and Figure 4 shown);

[0038] Then start the first motor 28, and the first motor 28 drives the conveyor belt 22 to rotate. When the conveyor belt 22 rotates, the push belt 23 pushes out the lowest stamping plate. At the same time, since the push belt 23 is designed to be higher than the conveyor belt 22, the push belt 23 can also support the upper stamping plate to prevent the stamping plate at the bottom from being pushed away. The gap above the conveyor belt 22 will cause the upper stamping plate to tilt, thereby affecting the normal transmission of the stamping plate, making the device more stable when in use.

[0039] Embodiment 2

[0040] This embodiment further improves the stamping assembly 3 on the basis of the first embodiment, so that the device can bend the stamping plate when in use.

[0041] like Figure 5 and Figure 6 As shown, the stamping assembly 3 includes a mounting plate 31 fixed to the upper end of the device base 1, and a roller group 32 with a vertically symmetrical design is fixed to the front end of the mounting plate 31, wherein the lower roller group 32 is adapted to the transmission wheel 11, so that the stamping plate transmitted by the transmission wheel 11 can continue to be transmitted, and at the same time, the roller group 32 adopts a vertically symmetrical design, and can also clamp the stamping plate when it is transmitted, to prevent the stamping plate from being displaced when the device bends the stamping plate, thereby affecting the bending accuracy of the device, each group of roller groups 32 includes a plurality of rollers arranged in an array, and an extension rod is slidably installed at one end of the roller, and a roller is also slidably installed at the front end of the extension rod, so that the roller group 32 The length in actual use can be adjusted so that it can be suitable for bending stamping plates of different lengths. A mounting plate 2 33 is also fixed to the front end of the roller group 32. The mounting plate 2 33 is connected to the mounting plate 1 31 by a telescopic bracket 34, wherein the telescopic bracket 34 is a prior art, and the telescopic bracket 34 is used to increase the stability of the roller group 32. Since the multiple rollers can also be telescopically designed, when the rollers are extended longer, the rollers will shake compared to the mounting plate 1 31. Therefore, the telescopic bracket 34 is required to support the end of the roller away from the mounting plate 1 31, so that the device is more stable when clamping and bending the stamping plate, and the front end of the mounting plate 2 33 below is also rotatably installed with an adjustment component 4.

[0042] like Figure 6 - Figure 8As shown, the adjustment component 4 includes a support plate 41, which is rotatably installed on the front end of the mounting plate 23 below, and mounting brackets 42 are fixed at both ends of the support plate 41. A limiting groove 43 is provided at the left end of the mounting bracket 42. A screw 44 is rotatably installed on the top surface of the inner cavity of the limiting groove 43, and a connecting block 45 is threadedly installed on the outer surface of the screw 44, wherein the limiting groove 43 is used for the installation of the screw 44 and the connecting block 45, and the limiting groove 43 can also play a role in limiting the connecting block 45. At the same time, due to the threaded connection between the screw 44 and the connecting block 45, the connecting block 45 can be moved upward or downward when the screw 44 is rotated, and one end of the two connecting blocks 45 is jointly fixed with a bending plate for bending the stamping plate The knife 46 is designed to be able to move upward or downward relative to the support plate 41 because the support plate 41 is rotatably connected to the mounting plate 33 below, and the connecting block 45 slides in the inner cavity of the limiting groove 43, so that the bending knife 46 can only move upward or downward relative to the support plate 41. When the support plate 41 rotates relative to the mounting plate 33, the bending knife 46 can also rotate relative to the mounting plate 33. A second motor 48 for driving the screw 44 is also provided at the upper end of the mounting bracket 42. The second motor 48 can drive the screw 44 to rotate when working. Due to the threaded connection between the screw 44 and the connecting block 45, the bending knife 46 can further move upward or downward. When the bending knife 46 moves downward, it can bend the stamping plate clamped by the two roller groups 32.

[0043] like Fig. 9 As shown, a rolling wheel 47 is rotatably installed at one end of the bending knife 46 close to the roller group 32. When the bending knife 46 bends the stamping plate, the rolling wheel 47 contacts the stamping plate. At the same time, due to the design of the support plate 41, the support plate 41 supports the stamping plate, and the bending knife 46 moves to the side away from the second motor 48, so that the rolling wheel 47 and the support plate 41 squeeze the stamping plate. When the rolling wheel 47 rolls and squeezes the stamping plate, the friction between the bending knife 46 and the stamping plate can be reduced, thereby reducing the wear of the stamping plate.

[0044] Furthermore, in order to facilitate the adjustment of the tilt angle of the support plate 41, as Figure 6 As shown, the inner cavity of the device base 1 is also provided with a lockable wire reel 5, the outer surface of the wire reel 5 is wrapped with a connecting wire, one end of the connecting wire is fixedly connected to the support plate 41, when the connecting wire contracts, the support plate 41 can be rotated, so that the bending angle of the device when bending the stamping plate can be adjusted.

[0045] The specific implementation of this embodiment is as follows: when the device is in use, the length of the second mounting plate 33 is adjusted according to different stamping plates, and then the inclination angle of the support plate 41 can be adjusted by adjusting the take-up reel 5. When the stamping plate moves between the two roller groups 32, the second motor 48 is started. The second motor 48 cooperates with the screw rod 44 and the connecting block 45 to move the bending knife 46 downward. When the bending knife 46 moves downward, it can stamp and bend the stamping plate.

[0046] At the same time, due to the design of the rolling wheel 47, while ensuring that the device can punch the punching plate, it can also reduce the friction between the bending knife 46 and the punching plate, thereby reducing the wear of the punching plate.

[0047] When designing the device, it is necessary to control the working time of the second motor 48 and the first motor 28 to prevent the storage component 2 from continuously transmitting the stamping plate when the device is bending the stamping plate, thereby affecting the normal bending operation of the device.

[0048] It should be noted that the specific installation method, circuit connection method and control method of the take-up reel 5, motor and roller group 32 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0049] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
