Description

Technical Field

[0001] The invention belongs to the technical field of packaging box compression resistance, and in particular, relates to an online compression resistance detection system and method for food packaging boxes. Background Art

[0002] Food packaging plays a vital role in the storage, transportation and sales of food. Its compression resistance directly affects the safety and integrity of food during transportation and storage. If the packaging box is not able to withstand enough pressure, it will be easily deformed or even broken when stacked or squeezed by external forces, causing food to be damaged, deteriorated or scattered, causing economic losses to the company and possibly affecting food safety.

[0003] A search of CN116148032A discloses an online compression resistance detection system and method for food packaging boxes. The present invention sets a driving mechanism on an extension plate. Under the action of the driving mechanism, the sliding seat moves intermittently on the base, and a pushing mechanism is provided between the base and the detection table. When in use, the pushing mechanism pushes the detection table to the conveying table on one side. After the compression resistance detection of the food packaging box is completed, it can be automatically pushed out for transportation, and then reset for the next operation. Before the next food packaging box is tested, the entire detection system does not need to stop working, and the next operation can be performed after resetting, which effectively improves the efficiency of the compression resistance detection of food packaging boxes.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0005] In actual use, it is found that the conveyor table is always in the state of conveying goods. Therefore, when pushing operations are carried out, the pushed goods may interfere with the goods conveyed inside the conveyor table, causing the goods to be squeezed together, damaged, or even dropped. In addition, when the inspection table drives the packaging box to move to the surface of the conveyor table, due to the large friction at the bottom of the packaging box, the packaging box may not be smoothly conveyed along the conveyor table, and the packaging box is still on the surface of the inspection table, affecting the normal use of the equipment.

[0021] As a preferred embodiment of the present invention, the detection method of the online compression resistance detection system of the food packaging box comprises the following steps:

[0022] Step 1: Place the food packaging box on the surface of the receiving table and test the compression resistance of the food packaging box using a compression tester;

[0023] Step 2: Start the drive motor, and drive the turntable to rotate through the drive motor. The inner groove on the turntable is offset from the position of the ejector rod. The turntable squeezes the ejector rod and the synchronous plate to slide outward. The synchronous plate drives the rocker arm to swing. The rocker arm rotates and drives the fence to rotate at the same time. The fence rotates to the conveyor belt. At this time, the packaging boxes transported on the conveyor belt are intercepted by the fence to ensure smooth unloading at the current station.

[0024] Step 3: The turntable drives the adjusting roller to rotate, and the adjusting slider on the adjusting roller slides from the blocking groove to the spiral groove. While the blocking groove slides, the rocker arm is in a rotating state. When it slides to the spiral groove, the rocker arm is in a stationary state, and the rotation of the spiral groove drives the adjusting slider to slide. The adjusting slider drives the receiving table to move through the vertical plate, and the packaging box on the receiving table is moved as a whole to the conveyor belt;

[0025] Step 4: During the movement of the receiving table, the synchronous slider is pushed on the T-shaped guide rail by the vertical plate to ensure that the push plate and the receiving table slide synchronously. When the synchronous slider moves to the end, the inclined positioning plate is clamped on the surface of the clamping block, and the positioning plate positions the synchronous slider as a whole;

[0026] Step 5: With the continuous rotation of the spiral groove, the receiving table moved to the unloading position begins to reset, but the positioning plate is in a stuck state, and the push plate is in a stationary state. Finally, the push plate and the receiving table are relatively displaced to ensure that the packaging box enters the conveyor belt smoothly. When the receiving table moves to the end, the slider is adjusted to squeeze the pressure plate, the pressure plate drives the push rod to move, the push rod pulls the U-shaped bracket to rotate, and the U-shaped bracket drives the positioning plate to rotate in the opposite direction, the positioning plate is separated from the block, and the push plate is pushed to reset.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] By providing a blocking unit, the turntable is driven to rotate by a driving motor, the inner groove on the turntable is offset from the position of the push rod, the turntable squeezes the push rod and the synchronous plate to slide outward, the synchronous plate drives the rocker arm to swing, the rotation of the rocker arm drives the guardrail to rotate at the same time, the guardrail rotates onto the conveyor belt, at this time the packaging boxes transported on the conveyor belt are intercepted by the guardrail, ensuring smooth unloading of the current workstation, the unloaded packaging boxes will not interfere with the packaging boxes on the conveyor belt, ensuring smooth transportation of the packaging boxes.

[0029] By providing a discharging unit, the turntable drives the adjusting roller to rotate, and the adjusting slider on the adjusting roller slides from the blocking groove to the spiral groove. While the blocking groove slides, the rocker arm is in a rotating state. When sliding to the spiral groove, the rocker arm is in a stationary state, and the rotation of the spiral groove drives the adjusting slider to slide. The adjusting slider drives the receiving table to move through the vertical plate, and the packaging box on the receiving table is moved as a whole to the conveyor belt. At this time, the packaging box is synchronously located above the conveyor belt. During the movement of the receiving table, the synchronous slider is pushed by the vertical plate to move on the T-shaped guide rail to ensure that the push plate and the receiving table slide synchronously. When the synchronous slider moves to the most end, the inclined positioning plate is clamped on the surface of the clamping block. At this time, the positioning plate positions the synchronous slider as a whole. With the continuous rotation of the spiral groove, the receiving table moved to the unloading position begins to reset, but the positioning plate is in a clamping state, and the push plate is in a stationary state. Finally, the push plate and the receiving table are relatively displaced to ensure that the packaging box enters the conveyor belt smoothly and the packaging box will not be stuck on the receiving table, so that the detection efficiency is higher.

At this time, the positioning plate 305 is separated from the block 3054, and then the guide spring 3035 is used to ensure that the push plate 3032 can be reset to the initial state, which is convenient for continued use in the future.

[0064] The present invention also discloses a detection method of an online compression resistance detection system for a food packaging box, the steps of which are as follows:

[0065] Step 1: Place the food packaging box on the surface of the receiving table 3021, and test the compression resistance of the food packaging box by using the compression resistance detector 401;

[0066] Step 2: Start the driving motor 201, and drive the turntable 202 to rotate through the driving motor 201. The inner groove 2021 on the turntable 202 is offset from the position of the push rod 2031. The turntable squeezes the push rod 2031 and the synchronous plate 203 to slide outward. The synchronous plate 203 drives the rocker arm 2043 to swing. The rocker arm 2043 rotates and drives the fence 204 to rotate at the same time. The fence 204 rotates to the conveyor belt 500. At this time, the packaging boxes transported on the conveyor belt 500 are intercepted by the fence 204 to ensure smooth unloading of the current station.

[0067] Step 3: The turntable 202 drives the adjusting roller 301 to rotate, and the adjusting slider 3013 on the adjusting roller 301 slides from the blocking groove 3012 to the spiral groove 3011. When the blocking groove 3012 slides, the rocker arm 2043 is in a rotating state. When sliding to the spiral groove 3011, the rocker arm is in a stationary state, and the spiral groove 3011 rotates to drive the adjusting slider 3013 to slide. The adjusting slider 3013 drives the receiving platform 3021 to move through the vertical plate 302, and the packaging box on the receiving platform 3021 is moved as a whole to the conveyor belt 500;

[0068] Step 4: During the movement of the receiving platform 3021, the vertical plate 302 pushes the synchronous slider 303 to move on the T-shaped guide rail 304 to ensure that the push plate 3032 and the receiving platform 3021 slide synchronously. When the synchronous slider 303 moves to the end, the inclined positioning plate 305 is clamped on the surface of the clamping block 3054. At this time, the positioning plate 305 positions the synchronous slider as a whole.

[0069] Step 5: With the continuous rotation of the spiral groove 3011, the receiving platform 3021 moved to the unloading position begins to reset, but the positioning plate 305 is in a locked state, and the push plate 3032 is in a stationary state. Finally, the push plate 3032 and the receiving platform 3021 are relatively displaced to ensure that the packaging box enters the conveyor belt 500 smoothly. When the receiving platform 3021 moves to the very end, the adjustment slider 3013 is squeezed with the pressure plate 3063, and the pressure plate 3063 drives the push rod 306 to move, and the push rod 306 pulls the U-shaped bracket 3051 to rotate, and the U-shaped bracket 3051 drives the positioning plate 305 to rotate in the opposite direction, and the positioning plate 305 is separated from the block 3054, and the push plate 3032 is pushed to reset.

[0070] The implementation principle of the online compression resistance detection system and method of a food packaging box of this embodiment is as follows:

[0071] The food packaging box is placed on the surface of the receiving table 3021, and the compression resistance of the food packaging box is tested by the compression detector 401, wherein the compression detector 401 is a prior art and the working principle is not described in detail here.

[0072] Then the operator starts the drive motor 201, and the drive motor 201 drives the synchronous shaft 2011 to rotate on the fixed frame 3014, and finally the synchronous shaft 2011 can drive the rotating disk 202 to rotate (the rotating disk 202 rotates clockwise to Figure 4 As a reference, and initially installed, the inner groove 2021 and the guide wheel 2032 fit together).

[0073] As the turntable 202 rotates, the inner groove 2021 on the turntable 202 is offset from the position of the push rod 2031, and the guide wheel 2032 at the end of the push rod 2031 rolls on the side wall of the turntable 202. The turntable 202 squeezes the push rod 2031 and the synchronization plate 203 to slide outward. The synchronization plate 203 can slide on the limit rod 2033, and the limit spring 2035 on the limit rod 2033 is compressed synchronously. The compressed limit spring 2035 facilitates the subsequent resetting operation.

[0074] When the synchronous plate 203 moves, the slide bar 2045 on the synchronous plate 203 can slide in the strip groove 2044 of the rocker arm 2043, and then the rocker arm 2043 drives the clamping shaft 2042 to rotate, and the clamping shaft 2042 can rotate in the fixed seat 2041, and the clamping shaft 2042 can also drive the guardrail 204 to rotate, and the guardrail 204 rotates onto the conveyor belt 500. At this time, the packaging boxes transported on the conveyor belt 500 are intercepted by the guardrail 204, ensuring that the current workstation can unload smoothly without interfering with the materials on the conveyor belt 500.

[0075] When the synchronous shaft 2011 rotates, the synchronous shaft 2011 can drive the adjusting roller 301 to rotate, and the adjusting slider 3013 on the adjusting roller 301 slides from the blocking groove 3012 to the spiral groove 3011. When the adjusting slider 3013 slides in the blocking groove 3012, the rocker arm 2043 is in the process of rotating and blocking the conveyor belt 500. When the adjusting slider 3013 slides to the spiral groove 3011, the rocker arm is in a stationary state, and the rotation of the spiral groove 3011 drives the adjusting slider 3013 to slide left and right (with the adjusting slider 3013 sliding in the spiral groove 3011). Figure 7 As a reference), the adjusting slider 3013 drives the receiving platform 3021 to move to the left first through the vertical plate 302, and moves the packaging box on the receiving platform 3021 as a whole to the conveyor belt 500.

[0076] During the movement of the material receiving table 3021, the synchronous slider 303 is pushed by the vertical plate 302 to move on the T-shaped guide rail 304, ensuring that the push plate 3032 and the material receiving table 3021 slide synchronously, wherein the protrusion 3033 on the synchronous slider 303 can slide on the guide rod 3034, wherein the guide spring 3035 on the guide rod 3034 is compressed synchronously, and the guide spring 3035 is used to facilitate the subsequent resetting operation.

[0077] When the synchronous slider 303 moves to the leftmost end, the inclined positioning plate 305 is clamped on the surface of the clamping block 3054, and the positioning plate 305 positions the synchronous slider as a whole;

[0078] When the receiving platform 3021 moves to the right, since the positioning plate 305 is in a locked state, the push plate 3032 is in a stationary state. Finally, the push plate 3032 and the receiving platform 3021 are relatively displaced, and the push plate 3032 slides in the receiving platform 3021. The push plate 3032 pushes the packaging box to enter the conveyor belt 500 smoothly.

[0079] When the receiving table 3021 moves to the far right, the adjusting slider 3013 is squeezed with the pressure plate 3063, and the pressure plate 3063 will slide along the positioning rod 3064, and the positioning spring 3065 on the positioning rod 3064 is convenient for the subsequent resetting operation, wherein the baffle 3066 ensures that the positioning rod 3064 and the pressure plate 3063 will not separate.

[0080] The pressure plate 3063 can drive the push rod 306 to move, and the push rod 306 slides inside the limit seat 3061, and the insertion rod 3062 at the end of the push rod 306 pulls the U-shaped bracket 3051 to rotate, and the U-shaped bracket 3051 drives the positioning plate 305 to rotate in the opposite direction. At this time, the positioning plate 305 is separated from the block 3054, and then the guide spring 3035 is used to ensure that the push plate 3032 can be reset to the initial state, which is convenient for continued use in the future.
