Description

Technical Field

[0001] This invention relates to the field of bamboo and wood processing machinery technology, specifically to a bamboo strip crushing device for the production of environmentally friendly packaging boxes. Background Technology

[0002] The bamboo strip crushing device for the production of environmentally friendly packaging boxes is a specialized mechanical equipment adapted to the characteristics of bamboo fiber. Its core function is to transform natural bamboo strips into uniform bamboo filaments through graded crushing, providing a skeleton or filling material for environmentally friendly packaging boxes. This device uses renewable bamboo as the processing material, replacing traditional wood or plastic fillers, which is in line with the concept of environmental protection. At the same time, through mechanical linkage design, it improves the efficiency of filament formation and reduces the breakage rate, ensuring both the environmental protection attributes of packaging box production and taking into account the practicality of production. It is a key supporting equipment for the environmentally friendly packaging industry.

[0003] Operators push bamboo strips into a multi-stage crushing roller assembly. Through gear linkage, the rollers rotate synchronously in opposite directions. With the help of an adaptive gap adjustment structure, the bamboo strips are gradually crushed into uniform bamboo filaments. The crushed bamboo filaments are then transported to the sorting mechanism through the discharge channel to complete length straightening and collection. The entire process relies on mechanical linkage to achieve semi-automatic operation without the need for additional power assistance. This meets the needs of renewable bamboo processing and aligns with the green concept of environmentally friendly packaging box production.

[0004] When manually pushing bamboo strips, fingers need to be close to the crushing roller or pre-compression roller at the feed inlet. If the bamboo strip slips, breaks, or the pushing force is too great, the fingers are easily caught in the crushing mechanism, causing work-related injuries such as squeezing and scratches. Especially when the end of the bamboo strip enters the equipment, the operator's hand will be too close to the feed inlet in order to prevent the bamboo strip from falling off or to adjust the feeding direction, which further increases the risk.

[0014] Beneficial effects The bamboo strip crushing device for producing environmentally friendly packaging boxes provided by this invention has the following beneficial effects: 1. As the extension slide bar continues to slide down, the contact shaft extends into the interior of the lower pressure groove, and the pressing block located directly above the feed groove slides down synchronously under the drive of the extension slide bar. At this time, the pressing block extends into the interior of the feed groove, thereby applying a downward pressure to both ends and the middle of the bamboo board located inside the feed groove. This restricts the range of motion of the bamboo board during the feeding process, reducing the problem of the bamboo board being too curved and not being restricted during the feeding process. This prevents the curved parts from leaving the feed groove, causing the bamboo board to deviate or get stuck during the feeding process, disrupting the feeding continuity, and leading to a decrease in the quality of the fibers. This ensures that the bamboo board is in full contact with the rolling roller surface during the feeding process, ensuring uniform fiber diameter and fiber integrity.

[0015] 2. The bamboo board is pushed between the feeding gears by the pushing mechanism. Compared with manually holding the bamboo board and pushing it between the feeding gears, the mechanical structure isolates the hand from the feeding gears, eliminating the risk of entanglement and making the protection more reliable. It can also achieve continuous and uniform pushing, eliminating the need for manual adjustment of the feeding direction according to the curvature of the bamboo board, which greatly improves the feeding rate and equipment utilization.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] refer to Figures 1 to 10 According to a preferred embodiment of the present invention, a bamboo strip crushing device for the production of environmentally friendly packaging boxes will be described in detail below. It includes a processing base 1, a processing component 11 on the upper surface of the processing base 1, a feeding port 12 on one side of the processing component 11, a side base 2 on the side of the processing component 11 near the feeding port 12, and a storage platform 21 on the upper surface of the side base 2. By stacking bamboo boards on the surface of the storage platform 21, it is easy to pick them up in the subsequent feeding process. A feeding groove 22 is opened on the upper surface of the storage platform 21. Two feeding gears are provided inside the feeding groove 22. The lower inner wall of the feeding groove 22 is located below the center line of the two feeding gears. By inserting bamboo boards between the two feeding gears, and the bamboo boards entering the processing component 11 under the pushing action of the two feeding gears, the crushing process is carried out. The storage platform 21 is equipped with a feeding mechanism that feeds bamboo boards into the feed inlet 12. The feeding mechanism inserts the bamboo boards into the processing component 11 for crushing. The surface of the storage platform 21 is equipped with a pressing mechanism that ensures the stability of the bamboo board feeding process. The pressing mechanism restricts the movement range of the bamboo boards placed in the feed trough 22 to prevent the bent bamboo boards from swinging back and forth during the feeding process. The storage platform 21 is equipped with a power mechanism that provides power to the pressing mechanism.

[0020] When the bamboo board is being rolled, the feeding mechanism inserts the bamboo board between two feeding gears. During this process, the pressing mechanism restricts the movement range of the bamboo board, thereby ensuring that the bamboo board slides stably during the feeding process. The bamboo board enters the processing assembly 11 under the pushing action of the two feeding gears, thereby performing the rolling process. like Figure 2 and Figure 3 In the middle, the power mechanism includes multiple extending grooves 3 arranged in a linear array on the surface of the storage platform 21, and extending slide rods 31 are slidably connected inside the extending grooves 3, such as Figure 4 In the middle, multiple extension grooves 3 are provided with power grooves 32 on the inner wall of their lower ends. Annular frames 33 are slidably connected inside the multiple power grooves 32. Extension circular plates 34 are rotatably connected inside the multiple annular frames 33. One end of the extension circular plate 34 is fixedly connected to the extension slide rod 31. A drive groove 35 is provided on the inner wall of the middle power groove 32 on the side away from the extension slide rod 31. A power telescopic rod 36 is provided inside the drive groove 35. The output shaft of the power telescopic rod 36 is fixedly connected to the annular frame 33. The extension circular plate 34 slides inside the annular frame 33 to ensure that the extension slide rod 31 does not rotate synchronously with the annular frame 33. A transverse connecting rod 37 is fixedly connected between adjacent annular frames 33. The power telescopic rod 36 drives the middle annular frame 33 to slide, and the transverse connecting rod 37 drives the adjacent annular frames 33 to slide downward synchronously.

[0021] like Figure 5In the process, the pressing mechanism includes a switching groove 4 formed on the inner wall of the extension slide 3. A switching circular frame 41 is fixedly connected to the inner wall of the switching groove 4. The extension slide rod 31 passes through the interior of the switching circular frame 41. An arc groove 42 is formed on the surface of the switching circular frame 41. The arc groove 42 is set from top to bottom from the side away from the feed chute 22 to the side close to the feed chute 22. A pressing groove 43 is formed on the inner wall of the lower end of the arc groove 42. A contact shaft 44 is fixedly connected to the surface of the extension slide rod 31. Initially, the contact shaft 44 is located inside the upper end of the arc groove 42. A connecting rod 45 is fixedly connected to the upper end of the extension slide rod 31. A pressing block 46 is fixedly connected to the surface of the connecting rod 45 away from the extension slide rod 31. The pressing block 46 is located on the side away from the feed chute 22 under the drive of the connecting rod 45.

[0022] The bamboo board needs to be inserted into the processing component 11, and the bamboo board is crushed into filaments by the processing component 11. When the bamboo board is placed inside the feeding trough 22, the output shaft of the power telescopic rod 36 pulls the extension slide rod 31 to slide down synchronously through the annular frame 33. At this time, the contact shaft 44 slides down synchronously under the pull of the extension slide rod 31, and the contact shaft 44 gradually rotates along the switching circular frame 41 from the side away from the feeding trough 22 to the side close to the feeding trough 22. At this time, the extension slide rod 31 rotates synchronously under the drive of the contact shaft 44. When the contact shaft 44 slides to the junction of the arc groove 42 and the lower pressing groove 43, the extension slide rod 31 rotates 180 degrees under the drive of the contact shaft 44. At this time, the extension slide rod 31 drives the pressing block 46 to rotate 180 degrees synchronously through the connecting rod 45, and the pressing block 46 is located directly above the feed groove 22. As the extension slide bar 31 continues to slide down, the contact shaft 44 extends into the interior of the lower pressure groove 43, and the pressing block 46 located directly above the feed groove 22 slides down synchronously under the drive of the extension slide bar 31. At this time, the pressing block 46 extends into the interior of the feed groove 22, thereby applying a downward pressure to both ends and the middle of the bamboo board located inside the feed groove 22, thus restricting the range of motion of the bamboo board during the feeding process. This reduces the problem of the bamboo board being not restricted during the feeding process due to its large curvature, preventing the curved parts from leaving the feed groove 22, which would cause the bamboo board to deviate or get stuck during the feeding process, disrupt the feeding continuity, and lead to a decrease in the quality of the filaments. This ensures that the bamboo board is in full contact with the surface of the pressing roller during the feeding process, ensuring uniform filament diameter and fiber integrity.

[0023] like Figure 6The power mechanism includes a push slide 5 located inside the storage platform 21. A slide bar groove 52 is formed on the inner wall of the push slide 5 on the side away from the processing base 1, extending out of the storage platform 21 away from the processing base 1. A power push block 51, which is U-shaped, is slidably connected inside the push slide 5. A resisting spring 59 is fixedly connected to the inner wall of the push slide 5, and the resisting spring 59 is fixedly connected to the power push block 51. Initially, the resisting spring 59 is in its normal state, and the power push block 51 is located within the push slide 5. Inside the slide groove 52 on the side away from the processing base 1, a feeding push rod 53 is slidably connected. The feeding push rod 53 extends out of the slide groove 52. A circular push plate is provided at the end of the feeding push rod 53 away from the power push block 51. By pushing the circular push plate, the power push block 51 is driven to slide synchronously. Both sides of the feeding groove 22 are provided with loading grooves 54. The loading grooves 54 are connected to the push slide groove 5. The protruding part of the power push block 51 extends into the loading groove 54 that is close to it. A connecting mechanism is provided on the upper surface of the power push block 51.

[0024] like Figure 6 and Figure 9 In the process, the connecting mechanism includes a guide rail 55 fixedly connected to the upper surface of the protruding part of the power push block 51. A power slider 56 is provided inside the feeding groove 54. The power slider 56 is engaged with the surface of the guide rail 55 and is slidably connected to the guide rail 55. A contact plate 58 is fixedly connected to the side of the two guide rails 55 that are close to each other. A support spring 57 is fixedly connected between the contact plate 58 and the power slider 56. A contact mechanism is provided inside the power slider 56. By sliding the power slider 56 on the surface of the guide rail 55, it is ensured that the power slider 56 slides stably back and forth along the surface of the guide rail 55. Initially, the power slider 56 is located on the side of the guide rail 55 away from the feeding groove 22, and the support spring 57 is in the normal state.

[0025] like Figure 9 In the process, the contact mechanism includes two extension slots 6 symmetrically opened inside the power slider 56. The inside of the extension slot 6 is slidably connected to the abutment slide plate 62. The inner wall of the extension slot 6 is fixedly connected to the extension spring 61. The extension spring 61 is fixedly connected to the abutment slide plate 62. The lower surface of the end of the abutment slide plate 62 away from the extension spring 61 is rotatably connected to the abutment wheel 63. The inner wall above the feeding groove 54 is provided with a feeding mechanism. Initially, multiple abutment wheels 63 are symmetrically distributed on both sides of the feeding groove 22. At this time, the extension spring 61 is in the normal state.

[0026] like Figure 7 and Figure 8In the feeding mechanism, there is an abutment groove 7 on the upper surface of the power slider 56. An abutment shaft 72 is slidably connected inside the abutment groove 7, and a connecting spring 71 is fixedly connected inside the abutment groove 7. The connecting spring 71 is fixedly connected to the abutment shaft 72. An inclined groove 73 is formed on the inner wall above the feeding groove 54. The inclined groove 73 gradually moves towards the feeding groove 22 from the end away from the processing base 1 to the end close to the processing base 1. A shrinkage groove 74 is formed at the end of the inclined groove 73 close to the feeding groove 22. The shrinkage groove 74 is L-shaped. One end of the horizontal part of the shrinkage groove 74 is connected to the inclined groove 73. A recovery groove 75 is provided between the end away from the feed trough 22 and the inclined groove 73 and the shrinkage groove 74. The depth of the end of the recovery groove 75 near the transverse part of the shrinkage groove 74 is greater than the depth of the inclined groove 73. The depth of the end of the recovery groove 75 near the abutment shaft 72 is less than the depth of the inclined groove 73. The depth of the end of the recovery groove 75 connected to the shrinkage groove 74 gradually decreases towards the end of the abutment shaft 72. The abutment shaft 72 extends into the interior of the inclined groove 73. A one-way mechanism is provided on the surface of the abutment wheel 63. Initially, the abutment shaft 72 is located inside the end of the inclined groove 73 away from the feed trough 22.

[0027] like Figure 10 In the process, the one-way mechanism includes a limiting circular groove 8 opened inside the abutting slide plate 62. The limiting circular groove 8 is arranged in a circumferential array with multiple inclined tooth grooves. A limiting circular plate 81 is fixedly connected to one side of the abutting wheel 63. The limiting circular plate 81 extends into the interior of the limiting circular groove 8. A pawl 82 is rotatably connected to the surface of the limiting circular plate 81 via a rotating shaft. A spring pawl 83 is fixedly connected to the surface of the limiting circular plate 81. The spring pawl 83 is located on the rotation path of the pawl 82. Initially, the spring pawl 83 is in the normal position, and the pawl 82 extends into the interior of the inclined tooth groove.

[0028] When the pressing block 46 extends into the feed trough 22 and restricts the movement range of the bamboo board, the feeding push rod 53 is manually pushed to slide towards the processing base 1, thereby driving the power slider 56 to slide synchronously through the power push block 51. During the process of the power slider 56 sliding towards the processing base 1, the abutment shaft 72 slides along the inclined surface of the inclined groove 73 under the drive of the power slider 56, and then drives the power slider 56 to move closer towards the feed trough 22 through the abutment shaft 72. When the contact shaft 72 is located at the junction of the inclined groove 73 and the shrinkage groove 74, the bamboo board on the surface of the feed groove 22 is clamped by the contact wheels 63 on both sides. As the contact shaft 72 extends into the interior of the shrinkage groove 74, the contact wheels 63 can only slide towards the processing base 1 under the contact of the pawl 82. Thus, the bamboo board is driven by the contact wheels 63 on both sides to slide synchronously with the power slider 56, thereby stuffing the bamboo board on the surface of the feed groove 22 between the two feed gears. The feed gears pull the bamboo board to slide, and the contact surface between the bamboo board and the contact wheel 63 drives the contact wheel 63 to rotate synchronously. At this time, the pawl 82 contacts the inclined groove, and the spring pawl 83 is compressed under the push of the pawl 82. When the abutment shaft 72 slides to the junction of the horizontal and vertical portions of the shrinkage groove 74, the abutment shaft 72 loses the restriction of the vertical portion of the shrinkage groove 74, and the power slider 56 slides away from the feed groove 22 under the push of the support spring 57. The abutment shaft 72 slides along the horizontal portion of the shrinkage groove 74 to the junction of the recovery groove 75 and the shrinkage groove 74. At this time, the abutment wheel 63 disengages from the inside of the feed groove 22. When the operator releases the force on the feed push rod 53, the power push block 51 slides away from the processing base 1 under the push of the contact spring 59. At this time, the contact shaft 72 slides along the inclined surface of the recovery groove 75 towards the inclined groove 73 under the drive of the power slider 56, until the contact shaft 72 falls back into the inclined groove 73 at the end away from the feed groove 22, so as to facilitate the next use. The bamboo board is pushed between the feeding gears by a pushing mechanism. Compared with manually holding the bamboo board and pushing it between the feeding gears, the mechanical structure isolates the hand from the feeding gears, eliminating the risk of entanglement and providing more reliable protection. It can also achieve continuous and uniform pushing, eliminating the need for manual adjustment of the feeding direction according to the curvature of the bamboo board, thus greatly improving the feeding rate and equipment utilization.

[0029] Working principle: When the bamboo board is being rolled, the feeding mechanism inserts the bamboo board between the two feeding gears. During this process, the pressing mechanism restricts the movement range of the bamboo board, thereby ensuring that the bamboo board slides stably during the feeding process. Under the pushing action of the two feeding gears, the bamboo board enters the processing component 11 for rolling. The bamboo board needs to be inserted into the processing component 11, and the bamboo board is crushed into filaments by the processing component 11. When the bamboo board is placed inside the feeding trough 22, the output shaft of the power telescopic rod 36 pulls the extension slide rod 31 to slide down synchronously through the annular frame 33. At this time, the contact shaft 44 slides down synchronously under the pull of the extension slide rod 31, and the contact shaft 44 gradually rotates along the switching circular frame 41 from the side away from the feeding trough 22 to the side close to the feeding trough 22. At this time, the extension slide rod 31 rotates synchronously under the drive of the contact shaft 44. When the contact shaft 44 slides to the junction of the arc groove 42 and the lower pressing groove 43, the extension slide rod 31 rotates 180 degrees under the drive of the contact shaft 44. At this time, the extension slide rod 31 drives the pressing block 46 to rotate 180 degrees synchronously through the connecting rod 45, and the pressing block 46 is located directly above the feed groove 22. As the extension slide bar 31 continues to slide down, the contact shaft 44 extends into the interior of the lower pressure groove 43, and the pressing block 46 located directly above the feed groove 22 slides down synchronously under the drive of the extension slide bar 31. At this time, the pressing block 46 extends into the interior of the feed groove 22, thereby applying a downward pressure to both ends and the middle of the bamboo board located inside the feed groove 22, thereby restricting the range of motion of the bamboo board during the feeding process. This reduces the problem of the bamboo board being not restricted during the feeding process due to its large curvature, and avoids the bent parts leaving the feed groove, which would cause the bamboo board to deviate or get stuck during the feeding process, disrupt the feeding continuity, and lead to a decrease in the quality of the filaments. This ensures that the bamboo board is in full contact with the surface of the pressing roller during the feeding process, ensuring that the diameter of the filaments is uniform and the fiber integrity is maintained.

[0030] When the power slider 46 extends into the feed trough 22 and restricts the movement range of the bamboo board, the feed push rod 53 is manually pushed to slide towards the processing base 1. This causes the power slider 56 to slide synchronously via the power push block 51. During the sliding of the power slider 56 towards the processing base 1, the abutment shaft 72 slides along the inclined surface of the inclined groove 73 under the drive of the power slider 56. This causes the power slider 56 to move closer to the feed trough 22 via the abutment shaft 72. When the abutment shaft 72 is located at the junction of the inclined groove 73 and the shrinkage groove 74, the bamboo board on the surface of the feed trough 22 is clamped by the abutment wheels 63 on both sides. As the abutment shaft 72 extends into the shrinkage groove 74, the abutment wheels 63 can only slide towards the processing base 1 under the abutment of the pawl 82. This causes the bamboo board to slide synchronously with the power slider 56 via the abutment wheels 63 on both sides, thus stuffing the bamboo board on the surface of the feed trough 22 between the two feed gears. The bamboo board is pushed between the feeding gears by a pushing mechanism. Compared with manually holding the bamboo board and pushing it between the feeding gears, the mechanical structure isolates the hand from the feeding gears, eliminating the risk of entanglement and providing more reliable protection. It can also achieve continuous and uniform pushing, eliminating the need for manual adjustment of the feeding direction according to the curvature of the bamboo board, thus greatly improving the feeding rate and equipment utilization.
