They have been replaced by plastic lunch boxes, paper lunch boxes, wooden lunch boxes, degradable lunch boxes, etc. Degradable lunch boxes are usually made of starch as the main raw material, and are produced by adding other plant fibers and special additives.

[0003] The patent CN221540302U discloses a high-efficiency disposable lunch box raw material stirring device, including a drum, a mixing device is fixedly connected to the middle of the lower end of the base, a fixing device is sleeved in the middle of the outer surface of the drum, a feed hopper is fixedly connected to the middle of the upper end of the mixing device, a feed slot is provided in the middle of the upper end of the feed hopper, a discharge pipe is fixedly connected to the right part of the outer surface of the mixing device, and a round cover is threadedly connected to the right part of the outer surface of the discharge pipe. The high-efficiency disposable lunch box raw material stirring device described in the utility model is used in conjunction with the provided mixing device and the connecting assembly, and a plurality of reinforcing rods are staggeredly distributed with the side rod as the center, so that the raw material stirring is disordered, and multiple disposable lunch box raw materials are further fully stirred, which greatly speeds up the stirring efficiency and effect, facilitates the cleaning of the inner wall of the drum, and is easy to operate, thereby improving work efficiency.

When the upper mold moves upward, it can drive the feeding gear and the feeding roller to rotate through the lifting rack. The feeding roller rotates to send the lunch box blank on the discharge support plate to the top of the lower mold. When the upper mold descends, it cooperates with the lower mold to cut and press the lunch box blank into shape, realizing the function of automatic feeding during the pressing process.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: A device for producing a degradable lunch box, such as Figure 1-Figure 10As shown, it includes a fixed bracket 1, a mixing barrel 101, a feeding frame 102, a control motor 103, a mixing shaft 104, a mixing belt transmission member 105, a spiral mixing blade 106, an inner baffle 107 and a discharging mechanism. The mixing barrel 101 is fixedly connected to the fixed bracket 1, and the feeding frame 102 is fixedly connected to the mixing barrel 101. The material is added to the mixing barrel 101 through the feeding frame 102, and then mixed evenly in the mixing barrel 101. The control motor 103 is installed outside the mixing barrel 101, and the inner baffle 107 is fixedly connected to the mixing barrel 101. The inner baffle 107 rotates on the inner baffle 107. A mixing shaft 104 is connected, and the control motor 103 is connected to the mixing shaft 104 through a mixing belt transmission part 105. The control motor 103 can drive the mixing shaft 104 to rotate through the mixing belt transmission part 105. The mixing shaft 104 is fixedly connected to a spiral mixing blade 106. The mixing shaft 104 rotates through the spiral mixing blade 106 and stirs and mixes the materials added into the mixing barrel 101. The discharging mechanism is installed in the mixing barrel 101. After mixing is completed, the discharging mechanism opens the bottom outlet of the inner partition 107 to allow the mixed materials to fall downward.

[0031] like Figure 2-Figure 6 As shown, the discharging mechanism includes a discharging barrel 1071, a reciprocating screw 2, a movable push plate 201, a guide rod 202, a lifting push plate 203, a first buffer spring 204, a lifting plate 205, a rotating baffle 206, a discharging push rod 207 and a stirring and anti-blocking component. The outlet on the inner partition 107 is fixedly connected with the discharging barrel 1071, and the mixed material falls downward through the discharging barrel 1071. The bottom of the inner partition 107 is rotatably connected with the reciprocating screw 2, and the reciprocating screw 2 is fixedly connected to the mixing shaft 104. The mixing shaft 104 can drive the reciprocating screw 2 to rotate. A guide rod 202 is fixedly connected in the mixing barrel 101, and a movable push plate 201 is slidably connected to the guide rod 202. The movable push plate 201 is threadedly connected to the reciprocating screw 2. When the reciprocating screw 2 rotates, the movable push plate 20 1 slides up and down along the guide rod 202, and the outer side of the discharge barrel 1071 is rotatably connected with a rotating baffle 206. The reciprocating screw rod 2 is slidably connected with a lifting push plate 203 and a lifting plate 205. The lifting push plate 203 is fixed with a vertical rod. The lifting plate 205 is slidably connected to the vertical rod at the top of the lifting push plate 203. The lifting push plate 203 and the lifting plate 205 are connected through a first buffer spring 204. One end of the first buffer spring 204 is fixed on the lifting push plate 203, and the other end is fixed on the lifting plate 205. A discharge push rod 207 is rotatably connected to the lifting plate 205, and the other end of the discharge push rod 207 is rotatably connected to the rotating baffle 206. The tumbling and anti-blocking assembly is installed in the discharge barrel 1071. The tumbling and anti-blocking assembly rotates and prevents materials from being blocked in the discharge barrel 1071.

[0032] The degradable base material, bamboo pulp and wood pulp are added into the mixing drum 101 through the feeding frame 102, and the raw materials fall on the inner partition 107 in the mixing drum 101. Then the control motor 103 is started, and the control motor 103 drives the mixing shaft 104 to rotate through the mixing belt transmission member 105. When the mixing shaft 104 rotates, the raw materials are stirred by the spiral mixing blades 106, so that the degradable base material, bamboo pulp and wood pulp are evenly mixed. During the rotation of the mixing shaft 104, the reciprocating screw 2 is driven to rotate, and during the rotation of the reciprocating screw 2, the moving push plate 201 is driven The movable push plate 201 slides up and down along the guide rod 202 during the mixing process. During the rising process of the movable push plate 201, it will contact the lifting push plate 203. Then the movable push plate 201 pushes the lifting plate 205 to rise through the lifting push plate 203, and the first buffer spring 204 rises accordingly. When the lifting plate 205 rises, the discharging push rod 207 drives the rotating baffle plate 206 to rotate, so as to open the bottom outlet of the discharging barrel 1071, so that the mixed materials can fall downward from the discharging barrel 1071. When the bottom of the plate 107 contacts, the mobile push plate 201 continues to push the lifting push plate 203 to rise, and the first buffer spring 204 between the lifting push plate 203 and the lifting plate 205 is compressed, so that the rotating baffle 206 remains in the open state for a long time, so that the materials mixed on the top of the inner partition 107 can all pass through the discharge barrel 1071 and fall downward. During the mixing process, the stirring and anti-blocking component will stir the materials in the discharge barrel 1071. During the discharging process, the stirring and anti-blocking component will continue to operate to prevent the materials from clogging the discharge barrel 1071. After the plate 201 rises to the highest point of the reciprocating screw 2, the reciprocating screw 2 continues to rotate, and the moving push plate 201 will slide downward along the guide rod 202. At this time, under the push of the first buffer spring 204, the lifting push plate 203 moves downward first. When the first buffer spring 204 returns to its original state, the lifting plate 205, the lifting push plate 203 and the first buffer spring 204 slide downward along the reciprocating screw 2 under the influence of gravity and return to their original state. The lifting plate 205 descends and pulls the rotating baffle 206 to rotate and return to its original state through the discharge push rod 207, and the bottom outlet of the discharge barrel 1071 is closed.

[0033] like Figure 5 and Figure 6As shown, the stirring and anti-blocking component includes a rotating push rod 1061, an arc-shaped rack 1062, a stirring gear 1072 and an anti-blocking spiral blade 1073. The rotating push rod 1061 is fixedly connected to the spiral mixing blade 106. The bottom surface of the rotating push rod 1061 contacts the top surface of the inner partition 107. The rotating push rod 1061 is fixedly connected to the arc-shaped rack 1062. The spiral mixing blade 106 drives the arc-shaped rack 1062 to rotate through the rotating push rod 1061. The discharging barrel 1071 is rotatably connected with the stirring gear 1072. The arc-shaped rack 1062 can engage with the stirring gear 1072 during rotation. The discharging barrel 1071 is rotatably connected with the anti-blocking spiral blade 1073. When the stirring gear 1072 rotates, it drives the anti-blocking spiral blade 1073 to rotate.

[0034] When the spiral mixing blade 106 rotates, the arc-shaped rack 1062 is driven to rotate by rotating the push rod 1061. When the arc-shaped rack 1062 rotates, it can engage with the stirring gear 1072. The arc-shaped rack 1062 can drive the stirring gear 1072 to rotate. When the stirring gear 1072 rotates, it drives the anti-blocking spiral blade 1073 to rotate. The anti-blocking spiral blade 1073 can stir the material in the discharge barrel 1071. A large space is left between the anti-blocking spiral blade 1073 and the discharge barrel 1071. During the discharging process, the anti-blocking spiral blade 1073 rotates from time to time to prevent the material from accumulating and clogging in the discharge barrel 1071.

[0035] Embodiment 2: Based on embodiment 1, Figure 3 , Figure 7 and Figure 8 As shown, it also includes a material receiving frame 3, a bottom baffle 301, a heating cylinder 302, an electric heating wire 303, a material discharging frame 304 and a rotating extrusion blade 305. The bottom of the mixing cylinder 101 is fixedly connected to the bottom baffle 301, and the material receiving frame 3 is fixedly connected to the bottom baffle 301. The material receiving frame 3 is located below the discharging cylinder 1071. The material falling downward through the discharging cylinder 1071 will enter the material receiving frame 3. The bottom baffle 301 is fixedly connected to the heating cylinder 302. The material receiving frame 3 passes through the bottom baffle 301 and is connected to the heating cylinder 302. The heating cylinder 302 is connected, and an electric heating wire 303 is fixedly connected to the outside of the heating cylinder 302. The material entering the heating cylinder 302 is heated by the electric heating wire 303. A discharge frame 304 is fixedly connected to the bottom outlet of the heating cylinder 302. A rotating extrusion leaf 305 is rotatably connected to the heating cylinder 302. The rotating extrusion leaf 305 is connected to the reciprocating screw rod 2. The reciprocating screw rod 2 drives the rotating extrusion leaf 305 to rotate, so as to extrude the heated material in the heating cylinder 302 into the discharge frame 304.

[0036] The stirred and mixed material passes through the discharge barrel 1071 and falls downward into the material receiving frame 3, and then the material slides downward along the material receiving frame 3 into the heating barrel 302. At this time, the electric heating wire 303 will heat the material in the heating barrel 302, and the rotating extrusion leaves 305 in the heating barrel 302 will rotate with the reciprocating screw rod 2. When the rotating extrusion leaves 305 rotate, they can extrude the heated material downward from the outlet at the bottom of the heating barrel 302, and the extruded material will enter the discharge frame 304, and then continue to slide downward along the discharge frame 304.

[0037] like Figure 3 and Figure 4 As shown, it also includes a feeding screw 4, a feeding barrel 401, a material storage barrel 402, a feeding push plate 403, a feeding baffle 404, a feeding push rod 405 and a control feeding assembly. The feeding screw 4 is rotatably connected in the feeding frame 102, the feeding barrel 401 is fixedly connected in the feeding frame 102, the material storage barrel 402 is fixedly connected to the top of the feeding frame 102, the feeding barrel 401 is communicated with the material storage barrel 402, the feeding baffle 404 is rotatably connected to the feeding barrel 401, the feeding push plate 403 is threadedly connected to the feeding screw 4, the feeding push plate 403 is rotatably connected to the feeding push rod 405, the other end of the feeding push rod 405 is rotatably connected to the feeding baffle 404, and the control feeding assembly is installed in the mixing barrel 101, and the control feeding assembly is used to connect the feeding screw 4 and the mixing shaft 104, so that the feeding screw 4 rotates and adds material into the mixing barrel 101.

[0038] like Figure 3 and Figure 4As shown, the control feeding assembly includes a spline shaft 2001, a sliding shaft 4001, a first lifting frame 406, a second lifting frame 407, a second buffer spring 408, a support spring 409, a connecting card plate 410 and a connecting ring 411. The spline shaft 2001 is slidably connected to the mixing shaft 104 and the reciprocating screw rod 2. A connecting ring 411 is fixed to the bottom of the spline shaft 2001. The second lifting frame 407 is slidably connected to the bottom partition 301. The first lifting frame 406 is slidably connected to the second lifting frame 407. The first lifting frame 406 and the second lifting frame 407 are connected through the second buffer spring 408. One end of the second buffer spring 408 is fixed to the first lifting frame 406, and the other end is fixed to the second lifting frame 407. A support spring 409 is provided between the second lifting frame 407 and the bottom partition 301. One end of the support spring 409 The second lifting frame 407 is fixed on the second lifting frame 407, and the other end is fixed on the bottom partition 301. When the push plate 201 is moved down along the reciprocating screw 2, it pushes the second lifting frame 407 to descend through the first lifting frame 406. A connecting card plate 410 is fixedly connected to the bottom of the second lifting frame 407, and the connecting card plate 410 is connected to the spline shaft 2001 through a connecting ring 411. A sliding shaft 4001 is slidably connected in the feeding screw 4, and the sliding shaft 4001 is connected to the spline shaft 2001. When the second lifting frame 407 descends, the spline shaft 2001 is pushed to slide downward by the connecting card plate 410 and the connecting ring 411. When the spline shaft 2001 drives the sliding shaft 4001 to slide downward, the sliding shaft 4001 will slide into the mixing shaft 104, so that the feeding screw 4 is connected to the mixing shaft 104, and the mixing shaft 104 can drive the feeding screw 4 to rotate through the sliding shaft 4001.

[0039] As the movable push plate 201 slides downward along the guide rod 202 driven by the reciprocating screw rod 2, the movable push plate 201 will contact the first lifting frame 406, and because the elastic force of the first buffer spring 204 is greater than the elastic force of the supporting spring 409, as the movable push plate 201 continues to descend, the first lifting frame 406 will push the second lifting frame 407 to descend through the second buffer spring 408, and the supporting spring 409 is compressed first. When the second lifting frame 407 descends, it drives the connecting card plate 410 to descend, and the connecting card plate 410 moves downward. The spline shaft 2001 is driven to descend along the mixing shaft 104 through the connecting ring 411, and the spline shaft 2001 drives the sliding shaft 4001 to slide downward along the feeding screw 4 and slide into the mixing shaft 104. At this time, the mixing shaft 104 is connected to the feeding screw 4 through the sliding shaft 4001. When the mixing shaft 104 rotates, it can drive the feeding screw 4 to rotate through the sliding shaft 4001. When the feeding screw 4 rotates, it drives the feeding push plate 403 to move upward. The feeding push plate 403 rises and pushes the feeding baffle 4 through the feeding push rod 405. 04 rotates, the feeding baffle 404 rotates to open the bottom outlet of the feeding barrel 401, and the material in the storage barrel 402 is added to the feeding frame 102 through the feeding barrel 401. After the feeding push plate 403 rises to the highest point, due to the bidirectional thread opened on the outside of the feeding screw 4, the feeding push plate 403 will move downward under the action of the feeding screw 4. When the feeding push plate 403 descends, the feeding baffle 404 is driven to rotate and reset through the feeding push rod 405 to block the bottom outlet of the feeding barrel 401, and the lifting push plate 203 descends to the reciprocating thread. After the rod 2 reaches the lowest point, it will rise again.
