Description

Technical Field

[0001] This utility model relates to the field of inspection machine technology, specifically to a waste removal device that effectively improves the waste detection rate. Background Technology

[0002] Currently, with technological innovation in the printing inspection industry, competition is intensifying, and printing plant customers are demanding higher speeds and greater capacity from their inspection machines. The speed of an inspection machine is affected by various components; any failure in any component will limit the machine's speed and consequently impact capacity. High-speed waste removal devices often use an air-blowing method. When the product width is too large or the paper weight is too heavy, waste products may not be able to enter the waste channel. Therefore, a waste removal device that can effectively remove waste products is needed to address the issues of air-blowing and excessively large product widths. Summary of the Invention

[0003] This utility model addresses the issue of waste removal devices using an air-blowing mode, where excessively large product widths or paper weights prevent waste from entering the waste channel. To resolve this, this application presents a waste removal device employing a box-tapping mode, effectively preventing waste from flowing into the bulk shipment due to excessive paper weight or width.

[0004] This utility model provides a scrap removal device that effectively improves the scrap detection rate. The scrap removal device is set on the original empty space of the detection mechanism and uses the original gate-shaped frame on the empty space. The waste removal device includes: The scrap board is kicked out, and the first end of the board edge is turned 90 degrees, while the second end is fixed with the main pivot. The main pivot penetrates the two side walls of the portal frame and is hinged to the portal frame. The main telescopic cylinder is located on the outside of the portal frame, and a second block is installed on the telescopic end; The first block is rectangular, with two circular through holes on its long side. The first through hole is used for detachable connection with the main rotating shaft. The block with the second through hole also has a U-shaped groove. The second block is inserted into the U-shaped groove and is hinged to the second through hole. The limiting head is coaxially set with the telescopic axis of the main telescopic cylinder and is located below the second block. The limiting head is made of plastic cylinder.

[0005] The device of this utility model adopts a scrap-kick mechanism. When the detection section of the detection mechanism detects a defective printed product, it sends a scrap-kick command to the scrap-kick device. When the front end of the defective printed product is conveyed to the empty area of ​​the detection mechanism, the traditional solution uses air blowing to make the defective printed product enter the waste channel downwards. However, the device of this application uses the first end of the scrap-kick plate to knock the defective printed product into the waste channel. At the same time, due to the existence of the 90-degree flip edge, the scrap-kick plate has a certain guiding effect.

[0006] The pneumatic telescopic cylinder drive mode has a faster response speed than traditional motor or spring structures. At the same time, the limit head setting avoids overshooting of the telescopic cylinder and also provides some assistance for the telescopic cylinder to reset.

[0007] Preferably, the support structure of the limiting head includes a metal push rod, a limiting cylinder, a spring structure, and a fixing block. The limiting head is fixed to the top of the metal push rod, which is sleeved on the center of the limiting cylinder. The middle section of the metal push rod has a protrusion to cooperate with the spring structure. The top surface of the fixing block has a through hole containing internal threads. The through hole is screwed to the limiting cylinder, and the bottom of the through hole is sealed. The limiting cylinder through hole forms an inner cavity, and a spring structure is installed inside the inner cavity.

[0008] The built-in spring structure of the limit pin helps to further reduce the pressure on the limit pin and extend its service life.

[0009] Preferably, with the axial parallel line of the main rotating shaft as the length direction, the length of the scrap kick plate is greater than the width between the outer walls of the detection mechanism.

[0010] Regarding the issue of excessively large paper width described in the background technology, the traditional air-blowing method not only fails to blow thicker paper but also has the problem of not being able to blow the edges. Therefore, the length of the scrap board determines the width of the unqualified printed products that can be scrapped.

[0011] Preferably, the first end of the scrap kick plate is close to the detection side of the detection mechanism, and the width of the scrap kick plate is greater than or equal to 3 times the diameter of the main rotating shaft and less than or equal to 4 times the diameter of the main rotating shaft.

[0012] Preferably, the waste-kicking device also includes an auxiliary baffle, which is set inside the portal frame, below the waste-kicking plate, and is the same width as the waste-kicking plate, and works in conjunction with the waste-kicking plate; the auxiliary baffle is set vertically, and both its upper and lower edges are provided with flanges.

[0013] The auxiliary baffle is designed to facilitate the removal of defective printed products. After some paper enters the waste removal channel, the waste removal baffle can be reset to prepare for the next waste removal, with the auxiliary baffle providing guidance.

[0014] The beneficial effects of this utility model are as follows: by adopting the box-making mode, the situation of waste products flowing into the bulk order due to excessive paper weight and paper width is effectively avoided, which can ensure the stability of product batches and improve customer satisfaction.

Detailed Implementation

[0016] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0017] like Figure 1 and Figure 2 As shown, the scrap removal device that effectively improves the scrap detection rate is set on the original empty area of ​​the detection mechanism and uses the original gate frame 1 on the empty area; The waste removal device includes: a waste removal plate 6, with a 90-degree flange at the first end and a main rotating shaft fixed at the second end; it is installed on the conveying plane formed by the detection section A1 and the output section A2 of the detection mechanism, and includes two working positions, the first working position as follows: Figure 1 As shown, this is the standby state, with the second working position... Figure 1 Based on this, it is rotated counterclockwise until it engages with the auxiliary baffle 7. Figure 2 The foundation is the first block 3 rotating clockwise.

[0018] The main pivot 4 penetrates the two side walls of the portal frame and is hinged to the portal frame. The main telescopic cylinder 2 is located on the outside of the portal frame, and a second block is provided on the telescopic end; The first block 3 is a rectangular block with two circular through holes on its long side. The first through hole is used for detachable connection with the main rotating shaft. The block with the second through hole also has a U-shaped groove. The second block is inserted into the U-shaped groove and is hinged to the second through hole. The limiting head 5 is coaxially set with the telescopic axis of the main telescopic cylinder and is located below the second block. The limiting head is made of plastic cylinder.

[0019] The device of this utility model adopts a scrap-kick mechanism. When the detection section A1 of the detection mechanism detects a defective printed product, it sends a scrap-kick command to the scrap-kick device. When the front end of the defective printed product is conveyed to the empty area of ​​the detection mechanism, the traditional solution uses air blowing to make the defective printed product enter the waste channel downwards. However, the device of this application uses the first end of the scrap-kick plate to kick the defective printed product into the waste channel. At the same time, due to the existence of the 90-degree flip edge, the scrap-kick plate has a certain guiding effect.

[0020] The pneumatic telescopic cylinder drive mode has a faster response speed than traditional motor or spring structures. At the same time, the limit head setting avoids overshooting of the telescopic cylinder and also provides some assistance for the telescopic cylinder to reset.

[0021] The supporting structure of the limiting head includes a metal push rod, a limiting cylinder, a spring structure, and a fixing block. The limiting head is fixed to the top of the metal push rod, which is sleeved on the center of the limiting cylinder. The middle section of the metal push rod has a protrusion to cooperate with the spring structure. The top surface of the fixing block has a through hole containing internal threads. The through hole is screwed to the limiting cylinder, and the bottom of the through hole is sealed. The limiting cylinder through hole forms an inner cavity, and a spring structure is installed inside the inner cavity.

[0022] The built-in spring structure of the limit pin helps to further reduce the pressure on the limit pin and extend its service life.

[0023] With the axial parallel line of the main rotating shaft as the length direction, the length of the scrap kick plate is greater than the width between the outer walls of the detection mechanism.

[0024] Regarding the issue of excessively large paper width described in the background technology, the traditional air-blowing method not only fails to blow thicker paper but also has the problem of not being able to blow the edges. Therefore, the length of the scrap board determines the width of the unqualified printed products that can be scrapped.

[0025] The first end of the scrap kick plate is close to the detection side of the detection mechanism. The width of the scrap kick plate is greater than or equal to 3 times the diameter of the main rotating shaft and less than or equal to 4 times the diameter of the main rotating shaft.

[0026] The waste-kicking device also includes an auxiliary baffle 7, which is set inside the portal frame, below the waste-kicking plate, and is the same width as the waste-kicking plate, and works in conjunction with the waste-kicking plate; the auxiliary baffle is set vertically, and both the top and bottom edges are provided with flanges.

[0027] The auxiliary baffle is designed to facilitate the removal of defective printed products. After some paper enters the waste removal channel, the waste removal baffle can be reset to prepare for the next waste removal, with the auxiliary baffle providing guidance.
