Description

[0001] This application is a divisional application of the application filed on October 9, 2025, with application number 202511434559X and invention title "A Continuous Intelligent Sorting Device for Defective Products in Food Production and Processing". Technical Field

[0002] This invention relates to the field of food sorting technology, and in particular to a continuous intelligent sorting device for defective products used in food production and processing. Background Technology

[0003] After food production and processing are completed, the integrity of the finished product packaging must be strictly inspected (to check for damage, missing seals, etc.), and qualified products must be accurately separated from defective products. This process requires the use of professional food defective product sorting equipment to ensure that the food that finally enters the market meets packaging safety standards.

[0004] In practical applications, most existing food defect sorting devices rely on camera equipment to visually detect damage to food packaging. However, as electronic components, camera equipment is prone to failure and damage during long-term, high-frequency use. Moreover, these devices usually require multiple camera devices, and to ensure accurate detection angles, they are often fixedly installed in specific locations on the device. This fixed layout makes it difficult for staff to quickly access and disassemble multiple camera devices, causing significant inconvenience for subsequent maintenance or replacement operations. This not only prolongs equipment downtime but may also affect food production efficiency. Summary of the Invention

[0005] This invention relates to a continuous intelligent sorting device for defective products in food production and processing. It only requires the rotation of a drive motor to quickly move two drive rollers inward, thus releasing the tension on the sorting belt. This allows the loosened sorting belt to be easily disassembled, facilitating replacement or maintenance. During the de-tensioning process, the corresponding structure also controls the rise of the limiting sleeve to release the clamping and positioning of the limiting plate, thus removing the fixation of the limiting plate and the sorting cylinder, facilitating disassembly, replacement, or maintenance of the sorting cylinder. When the limiting sleeve rises to release the positioning of the sorting cylinder, the corresponding structure also controls the clamping bar, clamping plate, and clamping turntable to move backward, so that the clamping turntable no longer clamps and positions the inspection camera on the fixed sleeve, facilitating replacement or maintenance of the inspection camera.

[0006] In a first aspect, this invention provides a continuous intelligent sorting device for defective products in food production and processing, specifically comprising: a support base and a detection frame; a drive rod rotatably mounted at the bottom of the support base; sliding grooves formed at the left and right ends of the rear side of the support base; a sliding block slidably mounted inside the sliding groove; a drive shaft rotatably mounted on the sliding block; a drive roller fixedly mounted on the outer circumference of the drive shaft; a sorting belt tensioned and mounted on the drive roller; a support plate fixedly mounted at the center of the inner side of the detection frame; limiting plates fixedly mounted on the left and right sides of the top of the support plate; a conversion component slidably mounted on the top of the support plate; a conversion plate fixedly mounted at the bottom rear side of the conversion component; a conversion groove formed on the rear side of the conversion plate; a detection plate fixedly mounted at the top front side of the detection frame; a fixing sleeve rotatably mounted at the center of the front side of the detection plate; a detection camera inserted inside the fixing sleeve; a clamping strip slidably mounted on the detection plate; a force-bearing groove formed at the bottom of the clamping strip; and a clamping disc fixed at the front end of the clamping strip.

[0007] Furthermore, the drive rod has two opposite threads symmetrically arranged; a drive motor is fixedly installed on the right side of the support base; the output shaft of the drive motor is splinedly connected to the right end of the drive rod.

[0008] Furthermore, the drive rod is connected to the sliding block via threads; a transmission component is fixedly installed on the inner side of the sliding block; a rotating motor is fixedly installed on the rear side of the sliding block on the left side; and the rear end of the drive shaft on the left side is splinedly connected to the output shaft of the rotating motor.

[0009] Furthermore, a collection box is placed on the bottom front side and bottom left end of the sorting belt; a transmission column is fixedly installed at the rear end of the transmission component; and the transmission component is slidably connected to the detection frame.

[0010] Furthermore, a sorting cylinder is placed on the support plate; a sorting push plate is fixedly installed on the output end of the sorting cylinder; limiting insert plates are fixedly installed on the left and right sides of the sorting cylinder; the limiting insert plates are inserted into the limiting plate.

[0011] Furthermore, the conversion groove has an inclined structure; the transmission column is slidably installed inside the conversion groove; and a limiting sleeve is fixedly installed on the inner side of the conversion component.

[0012] Furthermore, the limiting sleeve is pressed against the limiting insert plate while being fitted onto the limiting plate; a connecting plate is fixedly installed on the top of the conversion component.

[0013] Furthermore, a push block is fixedly installed at the center of the top of the connecting plate; the top of the push block has an inclined structure.

[0014] Furthermore, a locking bolt is threaded onto the outer wall of the fixing sleeve; the rear end of the force-bearing groove has an inclined structure.

[0015] Furthermore, a spring is embedded between the rear side of the clamping plate and the front side of the detection plate; a clamping turntable is rotatably mounted on the front side of the clamping plate; and the front side of the clamping turntable clamps and adheres to the detection camera.

[0016] This invention provides a continuous intelligent sorting device for defective products in food production and processing, which has the following beneficial effects: 1. Simply start the motor to rotate, and the two drive rollers will move inward quickly, simultaneously releasing the tension on the sorting belt. At this time, the sorting belt is in a loose state, and the staff can easily disassemble it, greatly simplifying the replacement or maintenance of the sorting belt.

[0017] 2. As the tension of the sorting belt is gradually released, the linkage structure of the device will synchronously control the limiting sleeve to move upward, thereby releasing the pressing and positioning of the limiting insert plate. This action can directly cancel the fixed relationship between the limiting insert plate and the sorting cylinder, enabling the sorting cylinder to be quickly disassembled, which is convenient for subsequent replacement or maintenance of the sorting cylinder.

[0018] 3. When the limiting sleeve rises and completely releases the positioning of the sorting cylinder, the corresponding transmission structure of the device will further control the clamping bar, clamping plate and clamping turntable to move backward as a whole. This action will cause the clamping turntable to disengage from the clamping state of the inspection camera, and no longer fix the inspection camera to the fixed sleeve, thus facilitating the replacement or maintenance of the inspection camera.

[0019] 4. With a single run of the drive motor, this sorting device can be quickly switched to the inspection standby state. In this state, the sorting belt remains loose, and the sorting cylinder and inspection camera are in a non-fixed state. All core components can be directly and quickly disassembled, which significantly improves the ease of replacement and maintenance of these key components. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please refer to Figures 1 to 8 Example 1: This invention proposes a continuous intelligent sorting device for defective products in food production and processing, comprising: a support base 1 and a detection frame 2. A drive rod 101 is rotatably mounted on the bottom of the support base 1. Sliding grooves 103 are formed on the left and right ends of the rear side of the support base 1. A sliding block 104 is slidably mounted inside the sliding groove 103. A drive shaft 107 is rotatably mounted on the sliding block 104. A drive roller 108 is fixedly mounted on the outer circumference of the drive shaft 107. A sorting belt 109 is tensioned and mounted on the drive roller 108. A support plate 201 is fixedly mounted at the center of the inner side of the detection frame 2. Limiting plates 202 are fixedly mounted on the left and right sides of the top of the support plate 201. A conversion component 206 is slidably mounted on the top of the support plate 201. The bottom of the conversion component 206 is... A conversion plate 207 is fixedly installed at the end; a conversion groove 208 is opened on the rear side of the conversion plate 207; a detection plate 2012 is fixedly installed on the top front side of the detection frame 2; a fixing sleeve 2013 is rotatably installed at the center of the front side of the detection plate 2012; a detection camera 2014 is inserted inside the fixing sleeve 2013; a clamping bar 2016 is slidably installed on the detection plate 2012; a force groove 2017 is opened at the bottom of the clamping bar 2016; a clamping disc 2018 is fixed at the front end of the clamping bar 2016; only the rotation of the drive motor 102 is needed to quickly move the two drive rollers 108 inward, canceling the tension of the sorting belt 109, making the loose sorting belt 109 easy to disassemble, and facilitating the replacement or maintenance of the sorting belt 109; The motor 106 operates, and under the action of the drive shaft 107 and drive roller 108, the motor 106 drives the sorting belt 109 to move, so that the sorting belt 109 transports the packaged food from right to left. During the transportation process, the detection camera 2014 will detect the food packaging during transportation. If the food packaging is damaged, the transmission module inside the detection camera 2014 can transmit the signal to the receiving module inside the sorting cylinder 203 in a timely manner, so that the sorting cylinder 203 controls the sorting push plate 204 to move forward and push the damaged food into the appropriate collection box, thereby realizing the sorting of defective products. Moreover, the detection mechanism in the device has two sets, which can continuously and intelligently sort, and it is not easy to miss the detection of defective products.

[0025] In Example 2, based on Example 1, two opposite threads are symmetrically formed on the drive rod 101; a drive motor 102 is fixedly mounted on the right side of the support base 1; the output shaft of the drive motor 102 is splinedly connected to the right end of the drive rod 101; the drive rod 101 is connected to the sliding block 104 via threads; a transmission component 105 is fixedly mounted on the inner side of the sliding block 104; a rotating motor 106 is fixedly mounted on the rear side of the left sliding block 104; the rear end of the left drive shaft 107 is splinedly connected to the output shaft of the rotating motor 106; a collection box is placed on the bottom front side and bottom left end of the sorting belt 109; the rear of the transmission component 105... A transmission column 1010 is fixedly installed at one end; a transmission component 105 is slidably connected to the detection frame 2; a sorting cylinder 203 is placed on the support plate 201; a sorting push plate 204 is fixedly installed on the output end of the sorting cylinder 203; limiting insert plates 205 are fixedly installed on the left and right sides of the sorting cylinder 203; the limiting insert plates 205 are inserted into the limiting plate 202; during the process of untensioning the sorting belt 109, the corresponding structure will also control the limiting sleeve 209 to rise and cancel the pressing and positioning of the limiting insert plate 205, and cancel the fixing of the limiting insert plate 205 and the sorting cylinder 203, so as to facilitate the disassembly of the sorting cylinder 203 and the replacement or maintenance of the sorting cylinder 203; When this device requires maintenance, the drive motor 102 can be started to rotate the drive rod 101. The drive rod 101 uses opposite threads to move the two sliding blocks 104, the two drive shafts 107 and the two drive rollers 108 inward relative to each other. The inward movement of the two drive rollers 108 cancels the tension on the sorting belt 109, which is convenient for the staff to disassemble, maintain or replace the sorting belt 109.

[0026] In Example 3, based on Example 2, the conversion slot 208 has an inclined structure; the transmission column 1010 is slidably installed inside the conversion slot 208; a limiting sleeve 209 is fixedly installed on the inner side of the conversion component 206; the limiting sleeve 209 is fitted onto the limiting plate 202 and also presses against the limiting insert plate 205; a connecting plate 2010 is fixedly installed on the top of the conversion component 206; a push block 2011 is fixedly installed at the center of the top of the connecting plate 2010; the top of the push block 2011 has an inclined structure; a locking bolt 2015 is threaded onto the outer wall of the fixing sleeve 2013; and the force-bearing slot 2017... The rear end has an inclined structure; a spring is embedded between the rear side of the clamping plate 2018 and the front side of the detection plate 2012; a clamping turntable 2019 is rotatably mounted on the front side of the clamping plate 2018; the front side of the clamping turntable 2019 clamps and adheres to the detection camera 2014; when the limiting sleeve 209 rises and cancels the positioning of the sorting cylinder 203, the corresponding structure will control the clamping bar 2016, the clamping plate 2018 and the clamping turntable 2019 to move backward, so that the clamping turntable 2019 no longer clamps and positions the detection camera 2014 on the fixed sleeve 2013, which facilitates the replacement or maintenance of the detection camera 2014; When the sliding block 104 moves inward, it also carries the transmission component 105 and the transmission column 1010 inward. During the inward movement, the transmission column 1010 uses the inclined structure of the conversion groove 208 to move the conversion plate 207, conversion component 206, limiting sleeve 209, and push block 2011 upward. This removes the limiting sleeve 209 from being fitted onto the limiting plate 202 and also eliminates the pressure on the limiting insert plate 205, allowing the limiting insert plate 205 and the sorting cylinder 203 to move freely, facilitating the disassembly and maintenance of the sorting cylinder 203. Alternatively, it can be replaced. Moreover, after the push block 2011 moves upward to a certain position, it will push the inclined surface of the force groove 2017, causing the force groove 2017 to be subjected to force, which will move the clamping bar 2016, clamping plate 2018 and clamping turntable 2019 backward. This will cause the clamping turntable 2019 to no longer apply clamping force to the inspection camera 2014, thus canceling the positioning of the inspection camera 2014. This makes it easier for the staff to remove the inspection camera 2014 from the inside of the fixing sleeve 2013, facilitating the maintenance or replacement of the inspection camera 2014.

[0027] The working principle of this embodiment is as follows: During use, the motor 106 is started, and its power is transmitted to the drive roller 108 via the drive shaft 107, driving the sorting belt 109 to rotate, thereby realizing the conveying of packaged food. During the conveying process, the detection camera 2014 performs real-time visual inspection of the moving food packaging. If packaging damage is detected, the built-in transmission module of the detection camera 2014 immediately sends a signal to the receiving module of the sorting cylinder 203, triggering the sorting cylinder 203 to control the sorting pusher 204 to move forward, thus... Damaged or defective food products are pushed into their corresponding collection boxes for sorting. The device is also equipped with two independent detection mechanisms for continuous intelligent sorting, effectively reducing the probability of missed defects. When maintenance is required, the drive motor 102 is activated, which rotates the drive rod 101. The drive rod 101, using opposite threads at both ends, moves the two sliding blocks 104, drive shaft 107, and drive roller 108 inwards, releasing the tension on the sorting belt 109. This allows workers to easily disassemble the sorting belt 109. During maintenance or replacement, as the sliding block 104 moves inward, it simultaneously drives the transmission component 105 and the transmission column 1010 to move inward. During the movement, the transmission column 1010, with the help of the inclined structure of the conversion groove 208, pushes the conversion plate 207, conversion component 206, limiting sleeve 209, and push block 2011 upward as a whole. This action not only disengages the limiting sleeve 209 from the limiting plate 202, but also releases the clamping and positioning of the limiting insert plate 205, allowing the limiting insert plate 205 and the sorting cylinder 203 to return to their active state. To facilitate the disassembly and maintenance or replacement of the sorting cylinder 203 by the staff, when the push block 2011 moves to a specific position, it will push the inclined surface of the force groove 2017. The force groove 2017 will transmit the force to the clamping bar 2016, which will drive the clamping plate 2018 and the clamping turntable 2019 to move backward, so that the clamping turntable 2019 no longer applies clamping force to the inspection camera 2014 and releases its positioning state. At this time, the staff can easily disassemble the inspection camera 2014 from the fixed sleeve 2013, which is convenient for maintenance or replacement operations.
