Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging box rejection, in particular to a defective product rejection structure for packaging box conveyance. Background Art
[0002] Conveyor systems play a vital role in the production and packaging of packaging boxes. These systems are typically responsible for smoothly and efficiently transporting boxes from production to the next processing stage, such as filling, sealing, or packaging. Defective product rejection mechanisms are a key component of box conveyor systems. Their primary function is to detect and quickly and effectively remove defective boxes from the production process, preventing them from entering the market.
[0003] However, existing rejection mechanisms have limitations when performing the rejection operation. In particular, push-rod rejection mechanisms, due to the long push rod, often require a brief production line stoppage to ensure safe and accurate operation when pushing defective products out. While this downtime is brief, in a continuous, high-speed production environment, frequent downtime can significantly impact overall production efficiency and output.
[0004] Therefore, the existing defective product rejection structure still has room for optimization in terms of improving production efficiency and reducing downtime. Utility Model Content
[0005] In view of this, the utility model provides a defective product rejection structure for packaging box conveying, which can reject defective products without stopping the machine, thereby improving production efficiency.
[0006] In order to solve the above technical problems, the utility model provides a defective product rejection structure for packaging box conveying, including a bracket and a pushing assembly, a pushing assembly is provided at the bottom of the bracket, the pushing assembly includes a support rod, a support plate, a telescopic rod, an electric push rod, a discharging rod and a rotating motor, one side of the bottom of the bracket is fixedly connected to the support rod, the bottom of the support rod is fixedly connected to the support plate, the side of the support plate close to the middle of the bracket is fixedly connected to the telescopic column, the top of the bracket is fixedly connected to the electric push rod, the telescopic end of the electric push rod is fixedly connected to the discharging rod, the bottom of the discharging rod is fixedly connected to the rotating motor, and the output shaft of the rotating motor is provided with the discharging assembly, which realizes the rejection of defective products without stopping the machine, thereby improving production efficiency and reducing downtime.
[0007] The telescopic end of the telescopic column is fixedly connected to a push plate, which expands the contact area and improves the accuracy and reliability of the rejection operation.
[0008] A plurality of pads arranged in an array are fixedly connected to one side of the push plate close to the bracket; that is, the friction between the push plate and the defective products is enhanced, ensuring the stability of the defective products during the removal process.
[0009] The discharging assembly includes a base plate and a discharging plate. The output shaft of the rotating motor is fixedly connected to the base plate. The bottom of the base plate is fixedly connected to two discharging plates symmetrically distributed with the rotating motor as the center. The base plate is circular, so that defective products can be removed stably and effectively, thereby improving the efficiency of the rejection process.
[0010] The discharge plates are all arc-shaped, and the inner arc surfaces of the discharge plates are all facing the middle of the bottom plate; that is, it helps to guide the defective products inward, avoiding side slippage or deviation during the discharge process.
[0011] The inner arc surface of the discharge plate is fixedly connected with multiple anti-slip strips distributed in an upper and lower array; that is, the friction is enhanced to prevent the defective products from sliding during the discharge process.
[0012] A slot is provided on one side of the bracket, the width of which is greater than the width of the discharge assembly, ensuring that defective products have enough space to pass through during the rejection process.
[0013] In summary, compared with the prior art, this application has at least one of the following beneficial technical effects:

[0024] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.
[0025] like Figure 1-4 As shown: This embodiment provides a defective product rejection structure for packaging box conveying, including a bracket 100 and a pushing assembly 200. The pushing assembly 200 is provided at the bottom of the bracket 100, and the pushing assembly 200 includes a support rod 201, a support plate 202, a telescopic rod 203, an electric push rod 204, a discharging rod 205 and a rotating motor 206. The support rod 201 is fixedly connected to one side of the bottom of the bracket 100, the support rod 201 is fixedly connected to the support plate 202 at the bottom, and the side of the support plate 202 close to the middle of the bracket 100 is fixedly connected to the telescopic column, the top of the bracket 100 is fixedly connected to the electric push rod 204, the telescopic end of the electric push rod 204 is fixedly connected to the discharging rod 205, the bottom of the discharging rod 205 is fixedly connected to the rotating motor 206, and the output shaft of the rotating motor 206 is provided with a discharging assembly 300;
[0026] When defective products need to be removed, the telescopic rod 203 is driven to extend and retract to directly push the defective products out of the transportation queue of the packaging box, and then the telescopic rod 203 is retracted. At this time, the transportation device is still running, and the electric push rod 204 is driven to run at the same time, driving the discharge rod 205 and the rotating motor 206 to approach the defective products. After the defective products are pushed out of the packaging box queue, the telescopic rod 203 only needs to extend a short distance to push the defective products out. The rotation motor 206 drives the discharge assembly 300 to receive the defective products and move the defective products out of the transportation device. In this way, the subsequent step of moving the defective products out of the transportation device will not affect the conveying process of other packaging boxes, thereby realizing the removal of defective products without stopping the machine, improving production efficiency and reducing downtime.
[0027] Push plate 101 Figure 1 、 2 As shown,
[0028] The telescopic end of the telescopic column is fixedly connected to a push plate 101;
[0029] The push plate 101 effectively expands its surface area, thereby increasing the contact area with defective products and ensuring that defective products are stably and effectively pushed out during the rejection process. This helps improve the accuracy and reliability of the rejection process and reduces the possibility of defective products being incompletely rejected or mistakenly rejected due to insufficient surface area of the push plate 101.
[0030] Pad 102 as Figure 2 As shown,
[0031] A plurality of pads 102 arranged in an array are fixedly connected to one side of the push plate 101 close to the bracket 100;
[0032] The spacer 102 increases the friction between the push plate 101 and the defective products, thereby improving the stability and reliability of the defective products during the rejection process. This increased friction helps ensure that the defective products do not slip or rotate when being pushed by the push plate 101, reducing the possibility of rejection failure or damage caused by unstable movement of defective products.
[0033] The discharge assembly 300 is as follows Figure 3 、 4 As shown,
[0034] The discharge assembly 300 includes a bottom plate 301 and a discharge plate 302. The output shaft of the rotary motor 206 is fixedly connected to the bottom plate 301. The bottom of the bottom plate 301 is fixedly connected to two discharge plates 302 symmetrically distributed around the rotary motor 206. The bottom plate 301 is circular.
[0035] When the defective products are pushed out of the packaging box queue, they are located at the bottom of the bottom plate 301. At this time, the rotation motor 206 is controlled to operate, driving the bottom plate 301 and the discharge plate 302 to rotate, so that the discharge plate 302 on one side rotates to the side of the defective products, and then the electric push rod 204 is driven to move to drive the discharge plate 302 to apply thrust to the defective products, and completely remove the defective products from the conveying queue. The two symmetrically arranged discharge plates 302 can prevent the defective products from falling to the other side when being moved, and provide support for the other side of the defective products. The stability of the defective products during movement is improved through the two discharge plates 302.
[0036] Discharge plate 302 Figure 4 As shown,
[0037] The discharge plates 302 are all arc-shaped, and the inner arc surfaces of the discharge plates 302 are all facing the middle of the bottom plate 301;
[0038] The arc shape can make the defective products move closer to the middle of the inner arc surface when discharging, preventing the defective products from sliding or deflecting when passing through the discharging plate 302, thereby ensuring the stability and accuracy of the discharging process.
[0039] Anti-slip strip 103 Figure 4 As shown,
[0040] The inner arc surface of the discharge plate 302 is fixedly connected with a plurality of anti-slip strips 103 distributed in an upper and lower array;
[0041] The anti-slip strip 103 can increase friction. During operation, when the rotary motor 206 drives the discharge plate 302 to rotate to the side of the defective products, the anti-slip strip 103 can effectively grab the defective products and prevent them from sliding during the discharge process.
[0042] Notch 104 Figure 1 、 3 As shown,
[0043] A slot 104 is formed on one side of the bracket 100 , and the width of the slot 104 is greater than the width of the discharge assembly 300 ;
[0044] The slot 104 leaves enough space for the defective products to be pushed out, ensuring that the defective products can pass through the bracket 100 smoothly during the rejection process. The width of the slot 104 is greater than the width of the discharge assembly 300, so that even if the discharge assembly 300 swings or deflects during the rotation process, the defective products have enough space to pass safely without colliding with the bracket 100.
[0045] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0046] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
