Description

Technical Field

[0001] The invention relates to the technical field of raw material processing, in particular to a device for processing raw materials of degradable packaging bags. Background Art

[0002] With the rapid development of the global economy and the improvement of people's living standards, the use of packaging bags in daily life and industrial production has increased dramatically. However, traditional plastic packaging bags, due to their non-degradable characteristics, have brought convenience while also causing serious pollution problems to the environment. These plastic packaging bags are difficult to decompose in the natural environment and have been accumulated in the land, rivers and oceans for a long time, not only occupying a large amount of land resources, but also causing serious damage to the ecosystem and biodiversity. In order to solve this problem, researchers and enterprises have begun to actively explore the research and development and production of degradable packaging bags. However, in the production process of degradable packaging bags, the processing of raw materials is a key link.

[0003] In the prior art, there is a device for processing raw materials for degradable packaging bags, such as the one disclosed in CN117341090A, which relates to the technical field of packaging bag processing, and comprises a first collecting box, the lower surface of which is fixedly connected to a first fixed block, the lower surface of which is fixedly connected to a supporting leg; a diverter device, by setting up the diverter device, raw materials with different particle sizes can be screened, so that when processing the packaging bags, raw materials with different particle sizes can be processed separately, the diverter device comprises a first clamping ring, the first clamping ring is fixedly connected to the lower surface of the first collecting box, a second clamping ring is sleeved on the inner cavity of the first clamping ring, the setting of the first clamping ring and the second clamping ring can enable the internal threaded ring to be connected to and removed from the first collecting box, so as to break up the agglomerated degradable packaging bag raw materials and sort the raw materials with different particle sizes.

[0004] In order to solve the problem that raw materials may agglomerate into lumps after being exposed to humid weather, thereby affecting processing efficiency, the prior art uses a breaking device to break up the agglomerated raw materials in the inner cavity of a processing box.

[0005] In actual use, the raw materials of degradable packaging bags are crushed first during pre-treatment. However, due to factors such as transportation and storage, some metal particles and impurities will be mixed in the raw materials. The metal particles and impurities can easily damage the blades during the pre-crushing of the materials, causing wear on the crushing knife group, reducing its service life and affecting the processing efficiency of the raw materials for the packaging bags.

[0006] Therefore, we proposed a degradable packaging bag raw material processing device to solve the problems of iron filings impurities mixed into the existing degradable packaging bag raw materials before pre-crushing, which causes wear of the subsequent crushing knife group and limited processing. When the raw materials are crushed, the raw materials can be further removed from the raw materials to improve the crushing processing effect of the raw materials. Summary of the invention

The raw materials enter the pretreatment cavity through the feed port 11. Under the linkage transmission action of the transmission mechanism 2, integrated transmission is realized to drive the raw material impurity removal mechanism 4 to operate as a whole, ensuring that the raw materials received on the receiving frame plate 42 are carried out in the process of horizontal movement. The iron filings particles mixed therein are adsorbed and screened out by the electromagnetic block 43 to avoid subsequent wear of the crushing knife group 214; the problem that the iron filings impurities mixed in the raw materials of the existing degradable packaging bags before pre-crushing cause subsequent wear of the crushing knife group and limited processing is solved. When the raw materials are crushed, the raw materials can be further cleaned, which improves the crushing processing effect of the raw materials and improves the yield rate of the final product.

[0039] Embodiment 2, refer to the attached Figure 1-16 On the basis of the first embodiment, in order to realize the integrated processing of the whole device, one driving source realizes the role of multiple linkages:

[0040] A driving pulley 211 is fixedly mounted on the output shaft of the motor 21, a driven pulley 212 is arranged on one side of the driving pulley 211, the outer surface of the driving pulley 211 is connected to the outer surface of the driven pulley 212 by a belt, a rotating rod 213 is fixedly mounted on the central inner surface of the driven pulley 212, a toothed disc 2131 is fixedly mounted on one end of the rotating rod 213, a toothed disc 2132 is meshed and rotated on the outer surface of one side of the toothed disc 2131, a rotating rod 2 is fixedly mounted on the central inner surface of the toothed disc 2132, and two groups of crushing knife groups 214 are arranged, and the two groups of crushing knife groups 214 are respectively mounted on the rotating rod 1 213 and the rotating rod 2. On the outer surface, two groups of crushing knife groups 214 are distributed in a staggered manner, and the crushing knife groups 214 include crushing teeth 2141 and cutting knives 2142. A driving pulley 22 is fixedly installed on the outer surface of one end of the rotating rod 1 213 close to the driven pulley 1 212. A driven pulley 221 is arranged on the outer side of the driving pulley 22. The outer surface of the driving pulley 22 is rotatably connected with the outer surface of the driven pulley 221 through a belt. The central inner surface of the driven pulley 221 is fixedly connected with a central rotating rod 222. The outer surface of the central rotating rod 222 is rotatably connected with the inner wall of the raw material crusher 1, and the outer surface of the central rotating rod 222 is fixedly connected with the central inner surface of the connecting turntable 41.

[0041] In this embodiment, when the raw materials of the degradable packaging bag are put into the raw material crusher 1 through the feed port 11, the raw materials will first enter the pretreatment chamber. At this time, the transmission mechanism 2 is controlled to be driven as a whole, and the driving motor 21 is turned on to rotate its output shaft, and its output shaft drives the active pulley 1 211 to rotate. Under the connection of the belt, the active pulley 1 211 and the driven pulley 1 212 rotate synchronously, and then drive the rotating rod 1 213 to rotate, and cooperate with the adaptive meshing between the toothed disc 1 2131 and the toothed disc 2 2132. The two groups of crushing knife groups 214 rotate in opposite positions, and the two groups of crushing knife groups 214 are staggered, so as to achieve efficient crushing of the raw materials; and under the continuous driving action of the motor 21, the active pulley 22 rotates, and drives the driven pulley 2 221 to rotate synchronously through the belt, as shown in the attached figure. Figure 3 It can be seen intuitively that the overall transmission of the raw material impurity removal mechanism 4 is realized in this way, and the overall device is designed as an integrated linkage, realizing the operation of multiple transmission structures driven by one motor, which greatly saves production energy consumption and reduces production costs.

[0042] Embodiment 3, refer to the attached Figure 1-16 On the basis of the second embodiment, in order to realize the continuous shaking and dropping of the material received on the receiving net 421:

[0043] The horizontal movable assembly includes a connecting turntable 41 and a material receiving frame plate 42. An eccentric boss 411 is fixedly installed on the outer surface of one side of the connecting turntable 41. The cross-section of the eccentric boss 411 is a "T"-shaped structure. The outer surface of the eccentric boss 411 is movably connected to a limited annular plate 412. One end of the limited annular plate 412 is fixedly connected to a sector tooth 413. The outer surface of the sector tooth 413 is meshed and rotated with a movable tooth plate 414. The outer surface of the movable tooth plate 414 is connected to the raw material crusher. 1 is slidably connected to the inner wall of the raw material crusher 1, the lower end of the movable tooth plate 414 is fixedly connected to the limited bottom plate 415, the deflection assembly includes a rotating motor 44, the rotating motor 44 is fixedly installed on the outer surface of one side of the raw material crusher 1, and a pin 441 is fixedly installed on the output shaft of the rotating motor 44, the outer surface of the pin 441 is rotatably connected to the inner wall of the raw material crusher 1, and two groups of pins 441 are provided, and one end of the two groups of pins 441 is respectively fixedly connected to the inner walls of the two ends of the material receiving frame plate 42;

[0044] In this embodiment, under the transmission action of the motor 21, the linkage transmission drives the central rotating rod 222 to rotate, thereby realizing the rotation of the connecting turntable 41, and the limiting annular plate 412 arranged on the outer side of the connecting turntable 41 moves within the upper limit of the eccentric boss 411. When the connecting turntable 41 rotates, the eccentric boss 411 moves eccentrically about the central axis of the connecting turntable 41, thereby realizing the left and right swinging of the limiting annular plate 412 and the sector teeth 413. Subsequently, the sector teeth 413 and the upper teeth of the movable tooth plate 414 are meshed with each other, thereby driving the horizontal limiting movement of the movable tooth plate 414. As shown in the attached Figure 4 , 11 As shown in Figure 12, the lower end of the movable tooth plate 414 is connected to the limiting bottom plate 415, and the outer surface of the limiting bottom plate 415 slides between the movable groove 31 provided on the inner wall of the lower end of the protective square cover 3, and the movable groove 31 provides an auxiliary limiting effect for the limiting bottom plate 415 to ensure the stable movement of the limiting bottom plate 415. Through such an arrangement, the limiting bottom plate 415 and the material receiving frame plate 42 connected to the inner side thereof can be effectively shaken to ensure the rapid separation of iron filings and impurities in the receiving material; and through the arrangement of the deflection component, the raw materials that have been shaken for a certain period of time are dropped, refer to Fig. 9 The specific operation is to control the driving of the rotating motor 44, and its output shaft rotates and drives the pin shaft 441 to rotate, so as to realize the deflection of the overall angle of the connecting material frame plate 42, so that the material received on the receiving net 421 can be quickly dropped and enter the subsequent crushing processing procedure, further solving the problem of iron filings impurities mixed in the existing degradable packaging bag raw materials before pre-crushing causing wear of the subsequent crushing knife group.

[0045] Embodiment 4, refer to the attached Figure 1-16 On the basis of the third embodiment, in order to realize the buffering protection of the material receiving frame plate 42 in the reciprocating horizontal activity, the present embodiment adds a buffer component:

[0046] A movable groove 31 is provided on the inner wall of the lower end of the protective square cover 3, and a buffer assembly is provided on the inner surface of the movable groove 31. The buffer assembly includes a guide rod 6, and both ends of the guide rod 6 are fixedly connected to the inner wall of the movable groove 31, and both ends of the guide rod 6 are slidably sleeved with a buffer spring 61, and both ends of the buffer spring 61 are fixedly connected to the inner wall of the movable groove 31, and the other end of the buffer spring 61 is fixedly connected to the outer surfaces of both sides of the limiting bottom plate 415, and the inner wall of the limiting bottom plate 415 is slidably connected to the inner wall of the guide rod 6;

[0047] In this embodiment, the movable groove 31 is provided to assist the limiting bottom plate 415 in limiting the position. Figure 13-14 As shown, when the limiting bottom plate 415 is subjected to left and right movement, the limiting bottom plate 415 is guided on the outer surface of the guide rod 6, and at this time, the buffer springs 61 at both ends of the guide rod 6 will be continuously pushed by the limiting bottom plate 415, and continuously generate compression deformation, so that the impact of the limiting bottom plate 415 is weakened by the elastic force of the buffer spring 61, and on the other hand, the shaking effect of the receiving material above the receiving net 421 can be increased, which can further accelerate the raw material processing efficiency and improve the raw material crushing effect.

[0048] Embodiment 5, refer to the attached Figure 1-16 On the basis of the fourth embodiment, in order to protect the entire material receiving frame plate 42 for receiving the material:

[0049] A receiving net 421 is fixedly provided at the lower end of the material receiving frame plate 42, and protruding rings 423 are fixedly connected to the two sides of the material receiving frame plate 42. The material receiving frame plate 42 and the protruding ring 423 are an integrally formed plate-shaped frame, and side grooves 4231 are respectively provided on the inner walls of the two sides of the protruding ring 423. The two ends of the electromagnetic block 43 are movably connected to the inner side of the protruding ring 423, and a quick-release component 5 is provided between the electromagnetic block 43 and the protruding ring 423; elastic collision strips 422 are also provided on the outer surfaces of the two sides of the material receiving frame plate 42, and the elastic collision strips 422 are arranged in two groups, and the two groups of elastic collision strips 422 are symmetrically distributed about the horizontal central axis of the material receiving frame plate 42, and the elastic collision strips 422 are made of soft elastic rubber material throughout;

[0050] In this embodiment, the raw materials of the degradable packaging bag introduced into the pre-treatment chamber are received by the receiving net 421. The protruding rings 423 are added on both sides of the receiving net 421 to assemble the electromagnetic block 43 as a whole inside. By adding elastic bumpers 422 on both sides of the receiving net 421, it can be ensured that during the reciprocating horizontal shaking of the receiving net 421, the side of the material receiving frame plate 42 is directly prevented from hitting the side wall of the raw material crusher 1. The elastic bumpers 422 enhance the protection effect on the material receiving frame plate 42. And the reason why the length of the elastic bumper 422 is longer than that of the protruding ring 423 is to prevent the protruding ring 423 and the electromagnetic block 43 inside it from falling or being damaged during the shaking process, further improving the range of raw material processing.

[0051] Embodiment Six. Refer to the attached Figure 1-16 , based on Embodiment Five, in order to achieve the rapid cleaning of the collected iron filings:

[0052] The quick-release component 5 includes a socket ring plate 51 and side sealing plates 55. The socket ring plate 51 is in a "convex" - shaped plate structure, and the connection end of the socket ring plate 51 with the electromagnetic block 43 is set as a "C" - shaped opening. The inner surface of the socket ring plate 51 is fixedly connected to both ends of the electromagnetic block 43. The side sealing plates 55 are fixedly installed on the outer surfaces of both sides of the protruding ring 423, and the side sealing plates 55 are in an overall "square" - shaped plate structure. A reserved groove 512 is opened at one end of the socket ring plate 51. An elastic support bar 53 is movably installed on the inner surface of the reserved groove 512. The elastic support bar 53 is in an overall "∞" - shaped plate structure. Both ends of the elastic support bar 53 are respectively fixedly connected with limit insertion rods 52. There are two groups of limit insertion rods 52, which are symmetrically distributed about the longitudinal central axis of the elastic support bar 53. The outer surfaces of both ends of the limit insertion rods 52 are respectively movably inserted into the inner wall of the side groove 4231 and extend to the outside of the side sealing plate 55. A receiving groove 511 is opened on the upper surface of the socket ring plate 51. A force - receiving rod 54 is slidably connected to the inner surface of the receiving groove 511. The force - receiving rod 54 is in an "L" - shaped plate structure. There are two groups of force - receiving rods 54, and the ends of the two groups of force - receiving rods 54 away from the receiving groove 511 are respectively fixedly connected to the upper ends of the limit insertion rods 52;

[0053] In this embodiment, socket ring plates 51 are respectively installed at both ends of the electromagnetic block 43. The outer surface of the socket ring plate 51 is adaptively clamped with the inner groove of the protruding ring 423, as shown in the attached Figure 5 、 6As shown in FIGS. 7 and 8, when the electromagnetic block 43 is disassembled as a whole, four fingers pinch the two groups of force rods 54 at the same time. At this time, the limiting rod 52 connected to the lower end of the force rod 54 is forced to move toward the inner side of the reserved groove 512 at the same time, and the elastic support bar 53 arranged between the two groups of limiting rods 52 is deformed by the squeezing force on both sides. When the limiting rod 52 is completely separated from the side sealing plate 55 and gradually separated from the side groove 4231, four fingers pinch the force rod 54 to pull the electromagnetic block 43 upward as a whole, so as to realize the connection between the electromagnetic block 43 and the material frame plate 42. The electromagnetic block 43 is disengaged from the groove 4231, thereby ensuring the rapid disassembly of the electromagnetic block 43 and facilitating the rapid cleaning of the iron filings adhering to its surface. When the cleaning is completed, when the electromagnetic block 43 is assembled to the inner side of the protruding ring 423, it is only necessary to pinch the force-bearing rod 54 again. When the limiting plug rod 52 is aligned with the side groove 4231, the force-bearing rod 54 is released simultaneously, and then the elastic support bar 53 is released. The certain elastic force generated pushes the limiting plug rod 52 through the side groove 4231 and into the groove opened on the inner wall of the side sealing plate 55, thereby realizing the rapid assembly of the electromagnetic block 43.

[0054] The working principle and use process of the present invention are as follows: in actual operation, first, plug in the external power supply, start the equipment, and the operator places the degradable packaging bag raw materials to be crushed into the pretreatment chamber opened on the upper part of the raw material crusher 1 through the feed port 11. At this time, the receiving net 421 is in a horizontal state and pre-receives the input materials; then, the transmission mechanism 2 is controlled to drive the movement as a whole, and the multiple groups of crushing knife groups 214 run at high speed. Under the continuous driving action of the motor 21, the active pulley 22 rotates, and the driven pulley 221 is driven by the belt to rotate synchronously, thereby realizing the overall transmission of the raw material impurity removal mechanism 4; furthermore, when the connecting turntable 41 rotates, the eccentric boss 411 moves eccentrically about the central axis of the connecting turntable 41, thereby realizing the limit. The annular plate 412 and the sector teeth 413 swing left and right, and then the sector teeth 413 mesh with the upper teeth of the movable tooth plate 414, driving the movable tooth plate 414 and the limiting bottom plate 415 to limit the movement in the horizontal direction, and the outer surface of the limiting bottom plate 415 slides between the movable groove 31 opened on the inner wall of the lower end of the protective square cover 3, to ensure the stable movement of the limiting bottom plate 415, and effectively shake the limiting bottom plate 415 and the receiving frame plate 42 connected to the inner side thereof, to ensure the rapid separation of iron filings and impurities in the received materials; in addition, the raw materials that have been shaken and removed impurities for a certain period of time are dropped through the deflection component, and finally, the impurity-removed materials enter the crushing chamber, to ensure the efficient crushing of the materials, and finally the crushed raw materials are discharged through the conveying mechanism at the lower end.
