If the specific posture changes, the directional indications will also change accordingly.

[0039] like Figure 1As shown in the utility model, the wine label product inspection machine comprises a paper feeding mechanism 2, a detection mechanism 3, a waste removing mechanism 4 and a paper collecting mechanism 5 arranged from front to back; the product output port of the paper feeding mechanism 2 is arranged correspondingly with the product input port of the detection mechanism 3; the product output port of the detection mechanism 3 is arranged correspondingly with the product input port of the waste removing mechanism 4; the finished product output port and the waste product output port of the waste removing mechanism 4 are arranged correspondingly with the finished product input port and the waste product input port of the paper collecting mechanism 5, and the specific introduction is as follows.

[0040] As shown in the utility model, Figures 3 to 5 The waste removing mechanism 4 comprises a waste kicking port arranged behind the product output port, a finished product conveying channel arranged above the waste kicking port and extending rearward, and a waste product conveying channel arranged below the waste kicking port and extending rearward and downward.

[0041] The finished product conveying channel comprises an upper belt pressing strip 403, two air blowing nozzles 401 arranged on both sides of the front end of the upper belt pressing strip 403, a suction box 402 mounted on the side surface of the front end of the upper belt pressing strip 403, an upper pressing strip belt 413 mounted on the bottom of the upper belt pressing strip 403, and a finished product conveying lower belt 414 arranged below the upper pressing strip belt 413; and the upper pressing strip belt 413 and the finished product conveying lower belt 414 both extend rearward to the finished product output port.

[0042] The waste product conveying channel comprises a waste product conveying upper belt 415 arranged below the finished product conveying lower belt 414, and a waste product conveying lower belt 416 arranged below the waste product conveying upper belt 415; and the waste product conveying upper belt 415 and the waste product conveying lower belt 416 both extend rearward and downward to the waste product output port.

[0043] And, as shown in the utility model, Figure 8 、 Figure 9 The upper pressing strip belt 413 is uniformly provided with a row of through holes along the length direction; the suction box 402 is a horizontally arranged U-shaped hollow shell, the top branch of which is arranged above the upper belt pressing strip 403, and the top surface of which is provided with a circular hole and mounted with a suction fan 412; the bottom branch of which is arranged below the upper belt pressing strip 403, and the bottom surface of which is uniformly provided with a row of long circular holes and is attached to the upper surface of the upper pressing strip belt 413.

[0044] The following is a detailed description of the working principle of each component of the waste removing mechanism 4.

[0045] The upper belt pressing strip 403 provides a stable conveying channel for the finished product.

[0046] The two blowing nozzles 401 are respectively placed above the two sides of the upper belt pressure strip 403. When waste is detected, the blowing nozzle 401 will blow air downwards, blowing the waste quickly and accurately to the waste conveying channel and into the space between the waste conveying upper belt 415 and the waste conveying lower belt 416. In addition, the air supply components of the two blowing nozzles 401 can adopt a conventional design, for example: consisting of a compressor, an air tank, a filter, and a pressure regulating valve. The compressor is responsible for compressing the air to a certain pressure and then storing it in the air tank. When the blowing nozzle 401 needs to work, the pressure regulating valve will adjust the air pressure in the air tank to a pressure suitable for the operation of the blowing nozzle 401. The filter is used to filter impurities and particulate matter in the air to protect the blowing nozzle 401 and other pneumatic components.

[0047] The upper layer belt 413 is installed along the length direction of the upper layer belt 403, and is characterized in that a row of through holes is evenly provided along the length direction. These through holes correspond to the oblong holes on the bottom surface of the suction box 402, forming a negative pressure adsorption channel together.

[0048] The suction box 402 is a hollow, special-shaped box that can be fixed to the side of the upper pressure strip 403 with screws. The upper pressure strip belt 413 of the previous inspection machine was not perforated, and there was no structure similar to the suction box 402. However, the top surface of the suction box 402 of the present invention is provided with a circular hole for connecting the suction fan 412; the bottom surface of the suction box 402 is a flat surface with a row of oblong holes, which are used to stick to the upper pressure strip belt 413. When the suction fan 412 is running, negative pressure is generated in the suction box 402, which is transmitted to the bottom of the upper pressure strip belt 413 through the oblong holes in the bottom of the box and the through holes on the upper pressure strip belt 413, so that the upper pressure strip belt 413 can absorb the product.

[0049] The finished product conveying lower belt 414 is placed below the upper layer belt 413 and is used to convey the finished products.

[0050] Described waste conveying upper belt 415 is placed below the finished product conveying lower belt 414, and tilts downwardly. When waste is blown off the finished product conveying line by the blowing nozzle 401, it can fall on the waste conveying upper belt 415, and be transported to the waste collection area.

[0051] Described waste conveying lower belt 416 is placed below waste conveying upper belt 415, and tilts downward and backward equally. It, together with waste conveying upper belt 415, stably transports waste to the waste collection area.

[0052] It should be noted that the upper pressure strip belt 413, the finished product conveying lower belt 414, the waste conveying upper belt 415, and the waste conveying lower belt 416 are single narrow belts, such as a 30 mm wide belt, so as to match the size of small papers such as wine labels.

[0053] In specific implementation, the working principle and process of the waste rejection mechanism 4 are as follows: when the wine label product on the suction belt 31 of the detection mechanism 3 is conveyed to the upper pressure strip belt 413 of the waste rejection mechanism 4, if the wine label product is detected to be a finished wine label product, the blowing nozzle 401 does not blow air, but the suction box 402 generates negative pressure, so that the upper pressure strip belt 413 absorbs the finished wine label product, ensuring that the finished wine label product will not fall or deflect during the conveying process, and then the upper pressure strip belt 413 and the finished product conveying lower belt 414 are supported up and down together, so that the finished wine label product passes smoothly through the waste rejection port and continues to be conveyed backward. If the detection mechanism 3 detects that the wine label product is a waste wine label, it issues a waste rejection instruction. At this time, the blowing nozzle 401 will blow air downwards, blowing the waste product quickly and accurately between the waste conveying upper belt 415 and the waste conveying lower belt 416, and then convey it to the waste conveying belt 407 of the paper collection mechanism 5 through the waste conveying channel, thereby achieving accurate waste rejection.

[0054] As can be seen, to accommodate the transport of small-sized paper such as wine labels, the waste rejection mechanism 4 utilizes an upper pressure strip belt 413 and a lower belt 414 for conveying finished products to form a finished product conveying channel, while an upper belt 415 and a lower belt 416 for conveying scrap products form a scrap conveying channel. Furthermore, each conveying channel utilizes a single, centrally positioned upper and lower belt clamping mechanism. Specifically, the upper pressure strip belt 413 and the lower belt 414 for conveying finished products are each a single, narrow belt positioned in the middle of the finished product conveying channel, supporting the finished product by placing it above and below it. Similarly, the upper belt 415 and the lower belt 416 for conveying scrap products are each a single, narrow belt positioned in the middle of the scrap conveying channel, supporting the scrap by placing it above and below it. Furthermore, through the coordinated use of the air nozzle 401 and the suction box 402, the waste rejection mechanism 4 enables rapid and accurate scrap removal, improving production efficiency and product quality.

[0055] In other embodiments, Figure 4 、 Figure 5 As shown, the waste rejection mechanism 4 also includes two finished product paper supporting bridge plates 404 and two waste paper supporting bridge plates 405; and the two finished product paper supporting bridge plates 404 are respectively placed on both sides of the finished product conveying lower belt 414; the two waste paper supporting bridge plates 405 are respectively arranged on both sides of the waste conveying lower belt 416.

[0056] Specifically, the waste rejection mechanism 4 is equipped with finished product paper supporting bridge plates 404 on both sides of the finished product conveying lower belt 414, and is equipped with waste paper supporting bridge plates 405 on both sides of the waste conveying lower belt 416, so as to assist the finished product conveying lower belt 414 and the waste conveying lower belt 416 in supporting large-size paper products, so that the products can be conveyed smoothly and the product application scope of the utility model is expanded.

[0057] In other embodiments, Figure 2As shown, the detection mechanism 3 includes a suction belt 31 connected to the inspection product output port and the inspection product output port, a main motor 36 that drives the suction belt 31, a detection light source 33, a detection camera 34, a detection photoelectric 32 and an encoder 35 installed above the suction belt 31, and a detection host; the detection photoelectric 32 is electrically connected to the encoder 35; the detection light source 33, the detection camera 34, and the encoder 35 are electrically connected to the detection host respectively; the detection host is electrically connected to the air supply component of the blowing nozzle 401.

[0058] The following is a detailed description of the components of the detection mechanism 3 and its working principle.

[0059] The main motor 36 is used to provide a power source to drive the suction belt 31 to operate.

[0060] The suction belt 31 is used to absorb the product evenly on the belt through adsorption force and transport it backward.

[0061] The detection light source 33 is used to provide stable and uniform lighting conditions to ensure that the detection camera 34 can capture clear and shadow-free images.

[0062] The detection camera 34 is used to take pictures of the product and capture image information of the product surface.

[0063] The detection photoelectric device 32 is used to cooperate with the encoder 35 to count steps and determine the position of the product.

[0064] The encoder 35 is used to be connected to the detection photoelectric 32 to record the moving distance and position of the product.

[0065] The inspection host is used to control the inspection light source 33, inspection camera 34, and encoder 35. It distinguishes finished products from rejects based on the collected data and inspection standards. The main quality defects of rejects include dirty spots, missing prints, pulled lines, ink flying, plate smearing, overprint offset, incomplete hot stamping, wrinkles, scratches, unevenness, missing varnish, and incomplete lamination. In addition, the inspection host controls the air supply unit of the air blowing nozzle 401, thereby controlling the timing of the air blowing nozzle 401's downward blowing.

[0066] In practice, the inspection mechanism 3 is specifically designed to inspect the surface quality of each product delivered by the paper feed mechanism 2. Its operating principle and process are as follows: A single wine label product delivered by the paper feed mechanism 2 is sucked and flattened by the suction belt 31 of the inspection mechanism 3, and then continues to be conveyed backward as the suction belt 31 rotates. As the wine label product passes through the inspection light source 33 and inspection camera 34, the inspection light source 33 provides stable illumination, while the inspection camera 34 takes a photo of the product, capturing image information of the label's surface. The inspection system analyzes and compares the captured image, determining whether the product is finished or defective based on pre-set inspection criteria. Furthermore, the inspection photoelectric sensor 32 cooperates with the encoder 35 to count the steps of the wine label product and determine its location. When a defective wine label is detected at the rejection port, the inspection mechanism 3 issues a rejection command, causing the blow nozzle 401 of the rejection mechanism 4 to blow air downward, blowing the defective label into the waste conveyor channel.

[0067] As can be seen from the above, the detection mechanism 3 is an efficient, accurate and automated quality detection system, which is of great significance for improving product quality and production efficiency, and has the following technical advantages:

[0068] a. High degree of automation: The entire detection process does not require human intervention, which improves production efficiency and accuracy.

[0069] b. High detection accuracy: Through the high-resolution detection camera 34 and the stable detection light source 33, tiny defects on the product surface can be captured.

[0070] c. Strong flexibility: It can be adjusted and optimized according to different product characteristics and testing standards.

[0071] d. Accurate waste removal: In conjunction with the waste removal mechanism 4, waste products can be accurately removed from the production line to prevent them from flowing into the next process.

[0072] In other embodiments, Figures 3 to 5 As shown, the paper collection mechanism 5 includes a finished product conveyor belt 406 connected to the finished product input port, and a waste conveyor belt 407 placed below the finished product conveyor belt 406 and connected to the waste input port; a finished product paper collection tray 408 is placed behind the finished product conveyor belt 406, and a finished product paper collection pressure wheel 410 is placed above it; a waste paper collection tray 409 is placed behind the waste conveyor belt 407, and a waste paper collection pressure wheel 411 is placed above it.

[0073] The following is a detailed description of the components of the paper delivery mechanism 5 and its working principles.

[0074] The finished product conveyor belt 406 is connected to the finished product conveying lower belt 414 of the waste rejection mechanism 4 and is responsible for conveying the finished paper from the waste rejection mechanism 4.

[0075] The finished product paper receiving tray 408 is placed behind the finished product conveyor belt 406 for receiving and stacking finished paper.

[0076] The finished paper delivery pressing wheel 410 is located above the finished paper delivery supporting plate 408, and helps the finished paper to be stacked into a fish scale shape on the conveyor belt by blocking, slowing down and pressing.

[0077] The waste conveyor belt 407 is located below the finished product conveyor belt 406 and is connected to the waste conveyor lower belt 416 of the waste rejection mechanism 4 to convey waste paper.

[0078] The waste paper receiving tray 409 is placed behind the waste conveyor belt 407 and is used to receive and stack waste paper.

[0079] The waste paper collecting and pressing wheel 411 is located above the waste paper collecting and holding plate 409, and also helps the waste paper to be stacked into a fish scale shape on the conveyor belt by blocking, slowing down and pressing.

[0080] It should be noted that the finished product conveyor belt 406 and the waste product conveyor belt 407 are single narrow belts, such as 30 mm wide belts, to match the size of small papers such as wine labels.

[0081] In specific implementation, the paper collection mechanism 5 is an efficient and orderly paper collection system, which is specially designed to process and sort finished and waste paper. Its working principle and process are as follows:

[0082] (1) Finished product collection: First, the finished wine labels delivered by the waste rejection mechanism 4 arrive at the finished product conveyor belt 406. The conveying speed of the finished product conveyor belt 406 is set to be slower than the conveying speed of the finished product conveying lower belt 414 in the waste rejection mechanism 4, so as to better control the stacking of the paper. At the same time, the finished product paper collection pressure wheel 410 blocks, slows down and presses the finished wine labels, so that the finished wine labels are stacked in a fish scale shape on the conveyor belt. Then, the stacked finished wine labels are slowly conveyed backwards to the finished product paper collection tray 408. Finally, on the finished product paper collection tray 408, the finished wine labels are manually collected into stacks.

[0083] (2) Waste collection: First, the waste wine labels conveyed by the waste rejection mechanism 4 arrive at the waste conveyor belt 407. The conveying speed of the waste conveyor belt 407 is also set to be slower than the conveying speed of the waste conveyor belt 416 in the waste rejection mechanism 4. In addition, the waste paper collection pressure wheel 411 blocks, slows down and suppresses the waste wine labels, causing the waste wine labels to be stacked in a fish scale shape on the conveyor belt. Then, the stacked waste wine labels are slowly conveyed backwards to the waste paper collection tray 409. Finally, on the waste paper collection tray 409, the waste wine labels are manually collected into stacks.

[0084] From the above, the function of the paper collecting mechanism 5 is to stack the finished products and waste products delivered by the waste removing mechanism 4 into a fish scale shape and deliver them to the respective paper collecting pallets, and finally collect them into stacks by manual operation, which has the following technical advantages:

[0085] 1. Efficient classification: through the separate design of the finished product conveying belt 406 and the waste product conveying belt 407, the finished products and waste products are quickly and accurately classified.

[0086] 2. Orderly stacking: the finished product paper collecting pressure roller 410 and the waste product paper collecting pressure roller 411 are used to block, slow down and press the paper, so that the paper is stacked into a fish scale shape on the conveying belt, which is convenient for subsequent manual collection.

[0087] 3. Strong adaptability: the single narrow belt design can well adapt to the size requirements of small paper such as wine labels.

[0088] 4. Easy to operate: the entire paper collecting mechanism 5 is simple in structure and easy to operate, which is convenient for daily maintenance and operation of the staff.

[0089] In addition, in order to adapt to small and thin printed matter, the utility model makes applicability adjustment in size, and the width and the grammage of the applicable product change as follows: the maximum width is 200*200mm, the minimum width is 53*42mm, the product grammage is 90-350g, and the fastest transmission speed is 150m / min.

[0090] In summary, the utility model provides an efficient and automated detection method for small printed matter such as wine labels, and the specific process is as follows:

[0091] A, place the product to be detected: place a stack of wine label products to be detected in the detection product placement place of the paper feeding mechanism 2.

[0092] B, paper feeding and conveying: the paper feeding mechanism 2 starts to work, and the wine label products are sent out one by one and sequentially enter the detection mechanism 3.

[0093] C, surface quality detection: the detection mechanism 3 detects the printing surface of each wine label product in detail. Through advanced image processing technology or sensor technology, the detection mechanism 3 can accurately judge the quality of the wine label product. At the same time, the detection mechanism 3 can also analyze the reasons for the specific quality defects of the waste wine label, such as printing errors, color difference, defects, etc.

[0094] D, waste removing operation: after the judgment of the detection mechanism 3, the waste removing mechanism 4 accurately removes the recognized waste wine label. The waste removing mechanism 4 usually adopts the blowing removing method to quickly and accurately separate the waste products from the main conveying line.

[0095] E. Collection and Stacking: Rejected waste wine labels are transported via waste conveyor belt 407 to waste paper collection tray 409. Meanwhile, qualified finished wine labels are transported via finished product conveyor belt 406 to finished product paper collection tray 408. On the paper collection mechanism 5, the finished wine labels and waste wine labels are manually collected and stacked separately for subsequent processing.

[0096] From the above, it can be seen that the utility model has the advantages of high efficiency, automation, high precision, clear classification and strong adaptability for the detection of small printed materials such as wine labels, providing strong technical support for the quality inspection of printed materials.

[0097] Although the principles of the present invention have been described in detail above in conjunction with preferred embodiments, those skilled in the art should understand that the above embodiments are merely illustrative of the implementation of the present invention and are not intended to limit the scope of the present invention. The details in the embodiments do not constitute a limitation on the scope of the present invention. Without departing from the spirit and scope of the present invention, any obvious changes such as equivalent transformations and simple substitutions based on the technical solutions of the present invention fall within the scope of protection of the present invention.
