Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste recycling, in particular to a paper knife, fork and spoon stamping waste recycling processing unit and method. BACKGROUND

[0002] Paper knife, fork and spoon is a disposable tableware made of food-grade paper or plant fiber (such as wood pulp, cane pulp) as raw material, which is used to replace traditional plastic knife, fork and spoon. Its core advantage is that it can be naturally degraded, which can significantly reduce "white pollution" and meet the global plastic restriction policy direction. The industrial production of paper knife, fork and spoon usually adopts multi-layer paper compounding and molding process to ensure product strength, hygiene and biodegradability. The main steps are to glue the multi-layer food-grade paper, then roll and compound it through multiple rollers to form the base material layer; then use a cutting knife or stamping equipment to cut the compounded paper into the main outline shape of knife, fork and spoon, which is similar to cutting out the preliminary shape of the mold; finally, put the cut paper into a special mold and mold it into a concave-convex shape (such as a spoon concave or a fork tooth part) through a hot press or hydraulic press.

[0003] At present, the utilization rate of single raw paperboard in the production of paper knife, fork and spoon by molding process is about 85% at most, so a large amount of stamping waste will be generated during production. After crushing, these wastes can be converted into paper pulp for reuse. At present, the stamping waste is mostly processed in single batches, that is, the weight of the paperboard is first determined, then a certain proportion of water is added for crushing according to the weight of the paperboard, and the next processing is carried out after the processing of this batch of waste is completed. However, this single processing method can process a small amount of waste in unit time, which is not conducive to improving work efficiency. The water ratio is not easy to control in the flow line processing method. If the water ratio is small, the load of the motor will increase, and the motor may be damaged seriously; if the water ratio is large, the paper will be dispersed, the crushing efficiency will be low, and the crushing effect will be poor.

DETAILED DESCRIPTION

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0039] The present application will be further described below in connection with the embodiments.

[0040] Embodiment: Reference Figures 1-11 A paper knife, fork, and spoon stamping waste recycling processing unit, comprising a processing tank 1, a crushing cylinder 3 is rotatably installed inside the processing tank 1, a crushing motor 4 is fixedly installed above the processing tank 1, a crushing knife 8 and a spiral knife 9 located inside the crushing cylinder 3 are installed on the driving shaft of the crushing motor 4. The crushing knife 8 provides the main crushing function, the spiral knife 9 can deliver the material downward under the condition of providing a certain crushing capacity, so that the waste always has a downward moving trend, so that the material entering the crushing cylinder 3 can be smoothly crushed by the crushing knife 8, and after the preliminary crushing by the crushing knife 8, it continues to move downward, with the accumulation of paper pulp, the paper pulp is forced to reach the upper part again to be processed by the crushing knife 8, which helps to improve the processing effect. As a better embodiment of the present application, the outer diameter of the spiral knife 9 is selected as half of the inner diameter of the crushing cylinder 3, so that the material delivered downward by the spiral knife 9 can move from the periphery of the spiral knife 9.

[0041] The pulverizing cylinder 3 comprises a cylinder body 301, an annular flange 302 is arranged on the outer wall of the top end of the cylinder body 301, an annular groove 7 is arranged on the inner wall of the top end of the processing tank 1, the annular flange 302 is rotatably arranged on the processing tank 1 through the annular groove 7, a discharge net 305 is arranged on the middle part of the cylinder body 301, the discharge net 305 is selected to have a proper aperture, so that the standard pulp particles are discharged from the discharge net 305 and fall into the processing tank 1, and a discharge pipe is arranged at the bottom end of the processing tank 1, so that the pulverized pulp can be discharged and wait for subsequent processing.

[0042] With reference to Figure 5 The inner wall of the annular groove 7 is provided with a fixed plate, the outer wall of the annular flange 302 is provided with a connecting plate 303 which is elastically connected with the fixed plate, the outer wall of the annular flange 302 is further provided with an electrode plate 304, the electrode plate 304 is provided with a contact electrode, the inside of the annular groove 7 is provided with two electrode sheets 71, the electrode plate 304 is located between the two electrode sheets 71, the top end of the processing tank 1 is provided with a water supply pipe 5, the water supply pipe 5 is provided with a solenoid valve, and the solenoid valve is opened when the contact electrode contacts any one of the electrode sheets 71.

[0043] When processing paper knife fork spoon stamping waste, the pulverizing motor 4 is kept on, and an appropriate amount of paperboard waste is continuously fed into the pulverizing cylinder 3, after the stamping waste enters the pulverizing cylinder 3, it is gradually changed into pulp particles through the crushing of the pulverizing knife 8 and the spiral knife 9, and the material in the pulverizing cylinder 3 is always rotating. Since the pulverizing cylinder 3 is elastically installed and rotatable through the connecting plate 303, when the pulp is too thick, the adhesion between the pulp and the inner wall of the pulverizing cylinder 3 will make the pulverizing cylinder 3 rotate by a certain angle, so that the contact electrode on the electrode plate 304 contacts the electrode sheet 71, the solenoid valve on the water supply pipe 5 is opened, water is added to the inside of the pulverizing cylinder 3, with the addition of water flow, the pulp becomes thin, the adhesion between the pulp and the pulverizing cylinder 3 becomes low, and the pulverizing cylinder 3 is reset under the action of the elastic force, and the solenoid valve is closed. Therefore, through the design of the present application, the function of automatically controlling the water adding time can be realized, and manual calculation of water adding amount is also not required, which is more efficient and convenient. The water adding time controlled by the solenoid valve each time can be set through a program, and it is not necessary to stop adding water until the pulverizing cylinder 3 is reset, because the pulp becomes thin with a certain hysteresis, and if the water adding is stopped until the pulverizing cylinder 3 is reset, excessive water may be added, which will cause the pulp to become thin. The specific water adding time can be set according to the actual situation, which will not be described here.

[0044] With reference to Figure 4, the spiral knife 9 is located below the crushing knife 8, so that the crushing knife 8 is located above the spiral knife 9, the waste is preliminarily crushed by the crushing knife 8 and then input to the lower part by the spiral knife 9, and then moves to the height of the crushing knife 8 again with the accumulation of the pulp and is further crushed, so that the crushing effect is improved. A plurality of convex ribs 306 are installed on the inner wall of the bottom of the crushing cylinder 3. The convex ribs 306 can hinder the pulp to some extent, so that the driving effect of the crushing cylinder 3 is more obvious when the pulp rotates, so that the crushing cylinder 3 can rotate a larger angle, and the solenoid valve can be stably opened.

[0045] Further, the discharge net 305 is located above the crushing knife 8. This design makes the height of the pulp accumulated in the crushing cylinder 3 always slightly higher than the crushing knife 8. The paperboard waste just falling into the inside of the crushing cylinder 3 can smoothly enter the inside of the pulp and be downwardly transported by the spiral flow generated by the spiral knife 9. After being fully crushed by the crushing knife 8 and the spiral knife 9, the paperboard waste is finally discharged, so that the crushing effect is ensured and the probability of the discharge net 305 being blocked is reduced. If the position of the discharge net 305 is lower, a large amount of pulp particles which are not completely crushed will be stuck on the discharge net 305, which will affect the smooth discharge of the pulp.

[0046] Referring to Figure 3 and Figure 4 , the upper and lower surfaces of the annular lap plate 302 are both installed with annular strips, and the top surface and the bottom surface of the annular groove 7 are both provided with clamping grooves matched with the annular strips. The positions of the crushing cylinder 3 are fixed by the matching of the annular strips and the clamping grooves, so that the crushing cylinder 3 can stably rotate.

[0047] Referring to Figure 2 and Figure 4 , the treatment tank 1 is also provided with a scraping mechanism 6. The scraping mechanism 6 comprises two symmetrical reciprocating screw rods 601. The two reciprocating screw rods 601 are both rotationally installed on the bottom wall of the treatment tank 1, and the bottom ends of the two reciprocating screw rods 601 both extend to the lower part of the treatment tank 1 and are synchronously connected. The bottom ends of the two reciprocating screw rods 601 are both installed with synchronous wheels 606, and the two synchronous wheels 606 are connected through a synchronous belt. One of the synchronous wheels 606 is driven by a motor installed at the bottom of the treatment tank 1 to rotate, so that the two reciprocating screw rods 601 can synchronously rotate. The two reciprocating screw rods 601 are both provided with lifting blocks 602. The lifting blocks 602 are both horizontally inserted with slide rods 603, and one end of the slide rod 603 is installed with a scraper 604 matched with the outer wall of the crushing cylinder 3. The inside of the treatment tank 1 is installed with a guide frame 605. The guide frame 605 controls the scraper 604 to move in a racetrack type route.

[0048] Referring to Figure 4 and Figure 8 , the guide frame 605 is provided with a guide groove 607. The guide groove 607 is in a racetrack type, that is, the two ends are in a semicircular rectangular structure, and the end of the slide rod 603 away from the scraper 604 is provided with a slide ball 608 matched with the guide groove 607.

[0049] The scraping mechanism 6 is started while the pulverizing motor 4 is working, and the two reciprocating wire rods 601 keep rotating to drive the two lifting blocks 602 to reciprocatingly move up and down, so that the sliding rod 603 follows the lifting. Since the sliding ball 608 is always located in the guide groove 607, when the sliding ball 608 reaches the bottom end and the top end of the guide groove 607, the sliding ball 608 enters the other side of the guide groove 607, so that the sliding rod 603 slips, and the scraper 604 moves accordingly. Therefore, when the scraper 604 reaches the bottom end, it is pulled to deviate from the outer wall of the pulverizing cylinder 3, and when the scraper 604 reaches the top end, it approaches the pulverizing cylinder 3 and is attached to the outer wall of the pulverizing cylinder 3, so as to achieve the effect that the scraper 604 does not scrape the paper pulp upward when moving upward. It is ingenious and convenient, and avoids that the paper pulp is dried on the outer wall of the pulverizing cylinder 3 to affect the subsequent use.

[0050] With reference to Figure 9 , the inner walls of the top end and the bottom end of the guide groove 607 are each provided with an elastic tab 609, which is flattened when the sliding ball 608 passes through and pushes the sliding ball 608 forward. Figure 9 For example, when the sliding ball 608 reaches the position of the elastic tab 609, the elastic tab 609 is flattened because the sliding ball 608 still needs to move downward. When the sliding ball 608 completely reaches the lowest end of the guide groove 607, the elastic tab 609 is released at this time and pushes the sliding ball 608 forward, so that the sliding ball 608 smoothly reaches the other side of the guide groove 607. When the lifting block 602 moves upward, the sliding ball 608 can move upward from the other side of the guide groove 607 instead of returning along the original route, so as to ensure that the scraper 604 can smoothly leave the pulverizing cylinder 3. It is simple and practical. The principle is the same when the sliding ball 608 reaches the top end of the guide groove 607.

[0051] With reference to Figures 1-11 , the upper side of one side of the treatment tank 1 is provided with a wetting mechanism 2, which includes a fixed seat 201. A feeding hole is horizontally formed in the fixed seat 201. A pushing opening 202 is formed in the end of the fixed seat 201 away from the treatment tank 1 and communicates with the feeding hole. Two pin rollers 203 are symmetrically installed in the inside of the pushing opening 202. The surface of the pin roller 203 is densely covered with pins. An upper water cavity 205 and a lower water cavity 206 are respectively formed in the inside of the fixed seat 201 and located on the upper side and the lower side of the feeding hole. A plurality of water permeable holes are formed in the top surface and the bottom surface of the feeding hole. A guide plate 204 is installed at the end of the fixed seat 201 close to the treatment tank 1, which is used to guide the wetted waste paper board from the feeding hole into the pulverizing cylinder 3.

[0052] The roller 203 can be driven to rotate by an external motor, and the rotating mode is opposite rotation. Alternatively, the stamping waste paper board can be directly pushed into the two rollers 203 by manual operation to achieve the feeding effect. When the waste paper board enters between the two rollers 203, the upper and lower surfaces of the waste paper board are pierced by the needles on the rollers 203. When the waste paper board enters the feeding hole, the water flow in the upper water cavity 205 and the lower water cavity 206 quickly penetrates into the inside of the waste paper board to wet the waste paper board, so that the waste paper board is softened, and the subsequent waste paper board is crushed faster and better, and the working efficiency is improved.

[0053] It should be noted that the depth of the lower water cavity 206 is not more than 10 mm, so that the water in the lower water cavity 206 can more easily escape upward to wet the waste paper board, without the need to provide a high water pressure, thereby reducing the equipment requirements.

[0054] The application also provides a paper knife, fork and spoon stamping waste recycling processing method, which is applied to the paper knife, fork and spoon stamping waste recycling unit, and includes the following steps.

[0055] S1: water flow is introduced into the upper water cavity 205 and the lower water cavity 206, and the water pressure is maintained, so that the lower water cavity 206 is always filled and escapes outward;

[0056] S2: the stamping waste is folded to a suitable thickness and pushed into the two rollers 203, the rollers 203 pierce the upper and lower surfaces of the stamping waste, the stamping waste enters the feeding hole and is wetted by the water flow in the upward and downward directions, and then enters the crushing cylinder 3;

[0057] S3: the stamping waste in the crushing cylinder 3 is repeatedly crushed by the crushing knife 8 and the spiral knife 9, the paper pulp meeting the size falls into the treatment tank 1 from the discharge net 305, and finally flows out of the treatment tank 1 for subsequent processing.

[0058] In the application, the specific installation mode of the treatment tank 1 and the wetting mechanism 2 is determined by the actual working environment, and the application only shows the connection relationship and combination mode between the components. The installation mode is a very conventional technical means for ordinary technical personnel in the field, and therefore is not described in detail in the application.

[0059] The above embodiments are only used to illustrate the technical solutions of the application, but not to limit the application; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not change the essence of the corresponding technical solutions out of the protection scope of the technical solutions of the embodiments of the application.
