Description

Technical Field

[0001] The invention relates to the technical field of lunch box production equipment, in particular to a degradable plastic lunch box production equipment. Background Art

[0002] Degradable tableware refers to tableware that can undergo biochemical reactions under the action of microorganisms (bacteria, mold, algae) and enzymes in the natural environment, causing changes in appearance and internal quality, and finally forming carbon dioxide and water. There are two types of materials used for degradable tableware: one is made of natural materials, such as paper products, straw, starch, etc., which are degradable and also called environmentally friendly products; the other is made of plastic as the main component, with starch, photosensitizers and other substances added.

[0003] Degradable lunch boxes are the main part of degradable tableware. The production process of degradable lunch boxes is roughly as follows: drying of raw materials, melt extrusion, cooling of sheets, blister forming, inspection, sorting and packaging, etc. In the production process of degradable lunch boxes, the sheets after blister forming are cut and separated, and then stacked by robotic arms, and then transferred to the packaging area for workers to check one by one, remove defective products, and then pack and give certificates of conformity to qualified products.

[0004] However, during the final step of inspection and packing, workers need to take out the stacked lunch boxes on the production line, move them to the workbench and check them one by one to confirm that there are no defective products. Then, they stack the lunch boxes into piles according to the approximate quantity and put them into packing boxes one by one. This process requires workers to have a certain estimate of the width of the packing boxes, and unskilled workers may spend more time.

[0033] See also Figure 1-6 The present invention provides a technical solution: a degradable plastic lunch box production device, comprising:

[0036] A conveying platform 8 is placed on the ground and is used to convey the packing box 7. A conveyor belt 81 is also provided on the conveying platform 8. The conveyor belt 81 can be driven on the conveying platform 8 to change the position of the packing box 7.

[0037] A clamping assembly 2, the clamping assembly 2 is located on the surface of the slide housing 1 and is used to block the lunch box from being divided into two parts;

[0038] The sensing component 3 is fixed on the slide housing 1 and is located below the clamping component 2;

[0039] A support platform 6 is placed on the ground to support other components;

[0040] Pushing component 1 4, which is located on the supporting platform 6, is used to push the lunch box into the packing box 7.

[0041] The clamping assembly 2 also includes a clamping member 21, a clamping member 22, a clamping plate 1 211, a clamping plate 221, a pin 23, a fixing block 24, a nut moving plate 25, a roller 27, a screw 1 28 and a power assembly 29; the clamping member 1 21 and the clamping member 2 22 are symmetrically distributed on the surface of the slide housing 1; the symmetry centers of the clamping member 1 21 and the clamping member 2 22 are connected through the pin 23; the clamping member 1 21 and the clamping member 2 22 are respectively rotatably connected to the pin 23; the clamping plate 1 211 and the clamping plate 2 221 pass through the slide housing 1 and are fixedly connected to the clamping member 1 21 and the clamping member 2 22, respectively, for clamping the lunch box; the fixing block 24 is fixedly connected to the pin 23, Used to support the lead screw 28; the lead screw 28 is rotatably connected to the fixed block 24 and the power assembly 29 respectively; the clamping member 21 and the clamping member 22 are also provided with a slide groove 26 symmetrical with respect to the pin shaft 23; there are two rollers 27, which can roll and slide in the slide groove 26; the two ends of the roller 27 are rotatably connected to the limit buckle 271, which is used to limit the position of the roller 27 to only be in the slide groove 26, and the diameter of the limit buckle 271 is larger than the diameter of the roller 27 and the width of the slot of the slide groove 26; the two ends of the nut moving plate 25 are rotatably connected to the roller 27 respectively, and the middle nut part cooperates with the lead screw 28; the power assembly 29 is used to provide power and support for the clamping assembly 2.

[0042] The power assembly 29 also includes a servo motor 291, a rotating shaft 292, a bevel gear 293, a bevel gear 294 and a support plate 295; the servo motor 291 is fixedly connected to the slide housing 1 for providing a power torque; the rotating shaft 292 is rotationally connected to the servo motor 291 for transmitting power; the bevel gear 293 is fixedly connected to the screw 28; the bevel gear 294 is fixedly connected to the rotating shaft 292 and meshes with the bevel gear 293; the support plate 295 is fixedly connected to the servo motor 291, and the other end is rotationally connected to the screw 28.

[0043] When the servo motor receives a signal drive, under the transmission action of the rotating shaft 292 and the bevel gear set, the lead screw 28 rotates, driving the nut moving plate 25 forward or backward; when the nut moving plate 25 moves forward or backward, it drives the roller 27 to roll, so that the clamping member 21 and the clamping member 2 22 move synchronously, driving the clamping plate 1 211 and the clamping plate 2 221 to be clamped or loosened synchronously in the sliding shell; when clamped, the clamping plate 1 211 and the clamping plate 2 221 block the lunch boxes falling from above, thereby separating the set number of lunch boxes.

[0044] The sensing component 3 also includes a laser emitter 31, a processor 32 and a laser sensing board 33; the laser emitter 31 is fixed on the slide housing 1 and is used to emit laser to detect the position of the lunch box; the laser sensing board 33 is used to receive laser signals; the processor 32 is used to process laser signal feedback and control the clamping component 2 and the pushing component 4.

[0046] When a lunch box falls from above in the slide housing 1, the laser emitter 31 will be blocked for a short period of time when the lunch box passes through the sensing component 3. At this time, the laser sensing plate 33 is blocked and cannot receive the laser signal; when the stacking height of the lunch boxes above the support platform 6 reaches the height of the sensing component 3, the laser emitter 31 will be blocked for a long time; when the laser sensing plate 33 does not receive the laser signal for a short time, the clamping component 2 will not move temporarily; after the laser sensing plate 33 does not receive the laser signal for a long time, the processor 32 sends an instruction to control the clamping component 2 to clamp. At this time, the lunch box falling from above will be clamped by the clamping component 2, and the lunch boxes above and below the clamping component 2 are separated.

[0047] After that, the push component 14 is activated, the servo motor 2 42 rotates to drive the lead screw 2 41 to rotate, and the nut support plate 1 44 is controlled to move, so that the vertical push plate 43 pushes the lunch box into the packing box 7 according to the set path. By setting the height of the laser emitter 31 and the laser sensor plate 33 to be the same as the width of the packing box 7, or setting the height of the laser emitter 31 and the laser sensor plate 33 to be slightly smaller than the width of the packing box 7, the number of lunch boxes pushed in each time can be controlled to roughly fill the packing box 7 vertically. Each time the push component 1 4 is pushed in, the conveyor 8 controls the conveyor belt 81 to move forward a distance of the width of the lunch box until one layer of the lunch box is filled. When one layer is full, the conveyor 8 controls the packing box 7 to move backward and refill the second layer. At this time, the vertical push plate 43 pushes forward a distance less than the distance of a box body than before, and so on and so forth until the packing box is completely filled.

[0048] The slideway housing 1 is also provided with an inspection slot 11, which is used to facilitate the operator to check whether the lunch box has fallen downwards. When the lunch box is stuck in the slideway housing 1, the lunch box can be moved by the inspection slot 11 to make it fall downwards.

[0049] According to the above embodiment, referring to Figure 5-7 , Embodiment 2:

[0050] A pushing component 2 5 is also provided on the support platform 6; the pushing component 2 5 also includes a lead screw 3 51, a servo motor 3 52, a horizontal moving plate 53 and a nut support plate 2 54; the servo motor 3 52 is fixed under the support platform 6; the lead screw 3 51 is rotatably connected to the servo motor 3 52; the horizontal moving plate 53 is located between the slide housing 1 and the support platform 6; the nut support plate 2 54 is fixedly connected to the horizontal moving plate 53, and the nut part at the other end cooperates with the lead screw 3 51.

[0051] After the processor 32 controls the clamping assembly 2 to clamp, the push assembly 1 4 and the push assembly 2 5 act simultaneously, respectively controlling the vertical push plate 43 and the horizontal moving plate 53 to move forward, at which time the stacked meal boxes are stacked on the horizontal moving plate 53; when the vertical push plate 43 and the horizontal moving plate 53 send the meal boxes into the packing box 7, the processor 32 controls the horizontal moving plate 53 to withdraw first, and then controls the vertical push plate 43 to withdraw. In this embodiment, when the push assembly 1 4 and the push assembly 2 5 push the meal boxes, the stability of the meal boxes is guaranteed when they are moved, and the meal boxes are prevented from tipping over during transportation.

[0052] According to the above embodiment, referring to Figure 5 , Embodiment 3:

[0053] The sensing assembly 3 also includes a pressure sensor 34, which replaces the laser emitter 31 and the laser sensing plate 33 and is located above the horizontal moving plate 53 to weigh the weight of the lunch box above. When the weight of the lunch box above the pressure sensor 34 reaches a set amount, the processor 32 controls the clamping assembly 2 to clamp and separate the lunch boxes. When the lunch box above the pressure sensor 34 is pushed away, the weight is reset, the clamping assembly 2 is released, and the process is repeated.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
