[0002] The long strip metal foil folding mechanism refers to a mechanism for folding long strip metal foil in half, stacking and forming a fold line, and then compacting the long strip metal foil. The existing long strip metal foil folding still relies on manual folding by workers, which not only has high labor intensity of workers and high cost of enterprises, but also has low efficiency. In addition, the folding precision may be affected by the proficiency of workers, and the demand cannot be met. SUMMARY

[0003] The present application provides a folding mechanism for folding long strip metal foil, which can fold long strip metal foil into foil with a fold line, and can replace manual folding of metal foil, thereby reducing labor, improving production efficiency and precision.

[0004] The technical scheme of the present application is implemented in the following manner:

[0005] The folding mechanism comprises a flexible horizontal progressive foil mechanism (1), a flexible vertical forming mechanism (2), an intermittent transmission composite gear train (3), a foil compacting and material returning mechanism (4), a base (5), and a foil end tensioning mechanism (6). The flexible horizontal progressive foil mechanism (1) is arranged on the base (5) and is bolted to the base (5) through a first sliding rail a (104a). The flexible vertical forming mechanism (2) is arranged on the flexible horizontal progressive foil mechanism (1) and is bolted to the horizontal sliding block connecting piece a (105a) through a second sliding rail a (208a), so as to move horizontally with the flexible horizontal progressive foil mechanism (1). The intermittent transmission composite gear train (3) can realize horizontal and vertical movement of the flexible horizontal progressive foil mechanism (1) and the flexible vertical forming mechanism (2). The foil compacting and material returning mechanism (4) is arranged on the base (5) and is bolted to the base (5) through a third sliding rail (408), so as to compact the aluminum foil after folding to form a fold line and return the obtained finished product. The foil end tensioning mechanism (6) is arranged on the base (5) and provides a certain tension to the aluminum foil. The parts in the flexible horizontal progressive foil mechanism (1), the flexible vertical forming mechanism (2), and the intermittent transmission composite gear train (3) are symmetric about the metal foil, and the upper part is named a and the lower part is named b.

[0006] The flexible horizontal progressive foil mechanism (1) comprises a first spring limiting piece a (101a), a first spring a (102a), a first slider a (103a), a first slide rail a (104a), a horizontal slider connecting piece a (105a), a bolt a (106a). The first spring limiting piece boss (101a-1) is perpendicular to the base (5), and the boss has two threaded through holes. The bolt a (106a) can be adjusted in the threaded hole. The first spring limiting piece boss (101a-2) is parallel to the base (5), and the boss has four through holes for connecting the bottom plate (5). The two first springs a (102a) are arranged in the threaded hole of the first spring limiting piece boss (101a-1) and the round hole of the horizontal slider connecting piece boss (105a-1). The first spring a (102a) can provide the first slider a (103a) with left elastic force after being compressed, realizing horizontal left movement. The first slider a (103a) is arranged on the first slide rail a (104a) and can slide thereon. The first slide rail a (104a) is connected to the base (5) by a bolt. The horizontal slider connecting piece boss (105a-1) is perpendicular to the base (5) and closely attached to the first slider a (103a) on one side. The boss has two through holes for limiting the spring. The horizontal slider connecting piece boss (105a-2) is horizontal to the base (5). The boss has four large holes for connecting the first slide rail a (104a) and two small holes for connecting the second slide rail a (208a).

[0007] The flexible vertical forming mechanism (2) comprises a second bolt a (201a), a second spring limiting part a (202a), a vertical sliding block connecting part a (203a), a folding knife fixing part a (204a), a folding knife a (205a), a second sliding block a (206a), a second spring a (207a), and a second sliding rail a (208a). The second spring limiting part boss (202a-1) is perpendicular to the base (5), and the boss has two threaded through holes. The second bolt a (201a) can be adjusted in the threaded hole. The first spring limiting part boss (202a-2) is parallel to the base (5), and the boss has four through holes for connecting the base plate (5). The vertical sliding block connecting part boss (203a-1) is perpendicular to the base (5), and the boss has two through holes for limiting the second spring a (207a). The vertical sliding block connecting part boss (203a-4) is parallel to the base (5), and the boss has four holes for connecting the second sliding block a (206a) and the folding knife fixing part a (204a). The vertical sliding block connecting part boss (203a-2) is perpendicular to the second sliding rail a (208a), and the lower side of the boss is in contact with the roller a (304a). The roller fixing part a (303a) drives the roller to rotate around the first shaft a (301a). The roller a (304a) lifts the vertical sliding block connecting part boss (203a-2) to realize the vertical movement of the mechanism. The vertical sliding block connecting part boss (203a-3) is parallel to the second sliding rail a (208a), and the cam a (305a) acts on the left side of the boss. The lift pushes the vertical sliding block connecting part boss (203a-3) to move to the right, thereby driving the overall mechanism to move to the right. The folding knife fixing part a (204a-1) is parallel to the base (5), and the boss has four through holes for connecting the vertical sliding block connecting part boss (203a). The vertical sliding block connecting part boss (203a-2) is perpendicular to the base (5), and the boss has two through holes for fixing the folding knife a (205a). The second sliding block a (206a) is arranged on the second sliding rail a (208a) and can slide thereon. The second sliding rail a (208a) is connected to the base (5) by a bolt.

[0008] The intermittent drive composite wheel train (3) comprises a first shaft a (301a), a first gear a (302a), a roller fixing piece a (303a), a roller a (304a), a cam a (305a), a third shaft a (306a), an incomplete gear a (307a), a fourth shaft a (308a), a second gear a (309a), and a third gear a (310a). The first gear a (302a) is connected with the first shaft a (301a) through a key. When the toothed part of the incomplete gear a (307a) meshes with the first gear a (302a) to drive, the first gear a (302a) rotates one circle. The roller fixing piece boss (303a-1) is parallel to the bottom plate, and the boss has a through hole which is in interference fit with the first shaft a (301a) and can rotate with the first shaft a (301a). The rod boss (303a-2) is perpendicular to the base (5), and the boss is in interference fit with the inner ring of the roller a (304a). When the roller fixing piece a (303a) rotates, it drives the roller a (304a) to rotate around the first shaft a (301a). When the roller a (304a) rotates to the uppermost position, the lifting height of the mechanism is the highest. The inner ring of the roller a (304a) is in interference fit with the roller fixing piece boss (303a-2), and the outer ring of the roller a (304a) can slide on (203a-2). The cam a (305a) can be divided into a folding knife folding stage, a feeding stage, and a horizontal mechanism non-working static stage. The folding knife folding stage and the feeding stage further include a push stage, a static stage, and a return stage. The time required for the push stage and the return stage is relatively short compared to the static stage. The angle of the static stage in the feeding stage is slightly smaller than that in the folding knife folding stage. In this way, the folding knife which is relatively far from the stop block can be returned to the stop block in advance by the spring action, so as to realize feeding. The third shaft a (306a) is connected with the second gear a (309a), the incomplete gear a (307a), and the cam a (305a) through a key. The incomplete gear a (307a) has toothed and toothless parts. When the toothed part meshes with the first gear a (302a), the first gear a (302a) rotates one circle, and the mechanism lifts. When the toothless part acts, the first gear a (302a) does not rotate, and the mechanism does not lift. The fourth shaft a (308a) is connected with the third gear a (310a) through a key, so as to rotate the fourth shaft a (308a) to realize transmission.

[0009] The foil compaction and unloading mechanism (4) includes a stop block (401), a handle (402), a torsion spring (403), a plunger (404), a third spring (405), a bolt (406), a limit block (407), a third slide rail (408), a third slider (409), a third connecting plate (410), and a hinge (411). The stop block (401) has a U-shaped cross-section and is hollow inside. It is bolted to the third connecting plate (410). The folded long strip of metal foil will continuously enter the cavity. The handle boss (402-1) is a boss for the worker to grip. The worker can grab the boss and rotate it. The handle boss (402-2) is used to limit the slider. Since the long strip of metal foil will exert a certain force on the plug (404) when it enters the stop block (401), the entire unloading mechanism will move to the left. The handle boss (402-2) can push against the third slide rail (408) to prevent it from moving to the left. The torsion spring (403) is set in the groove of the handle (402) and the stop block (401). The plug (404) can be positioned relative to the stop block. (401) Sliding, when the folded aluminum foil enters the stop (401), it will push against the plug (404) and move to the left relative to the stop. The plug boss (404-2) has a hole for placing the third spring (405). The third spring (405) will give the plug boss (404-2) a force to the right. In this way, the folded metal foil will be subjected to a force to the right during storage, thereby achieving a certain compaction effect. The third connecting plate (410) is set on the third slider (409) by bolts. The third slider (409) is set on the third slide rail (408) and can slide relative to it. The third slide rail (408) is connected to the base (5) by bolts and is parallel to the first slide rail (104).

[0010] The foil end tensioning mechanism (6) includes a fixing member (601), a friction wheel (602), and an aluminum foil (603).

[0011] An intermittent long strip metal foil folding mechanism has the following effects:

[0012] 1) When the flexible vertical forming mechanism moves vertically, the pushing stroke is achieved through incomplete gear meshing, and the return stroke is achieved through spring force, thus avoiding rigid impact during the transmission process.

[0013] 2) When the flexible horizontal progressive foil mechanism moves horizontally, the push stroke is achieved by the cam and the return stroke is achieved by the spring force, thus avoiding rigid impact during the transmission process.

[0014] 3) Only one power source drives the entire folding mechanism, making the transmission more precise and the cost lower.

[0015] 4) The cam and incomplete gear transmission structure is simple and compact, and the cam profile and the number of teeth of the incomplete gear can be easily designed to achieve the expected motion law of the horizontal and vertical followers.

[0016] 5) Foil compaction mechanism can be folded after the aluminum foil compaction, and then the finished material, the worker simple operation. BRIEF DESCRIPTION OF DRAWINGS

[0033] As Figure 1-6 shown, an intermittent long strip metal foil folding mechanism includes a flexible horizontal progressive foil mechanism (1), a flexible vertical forming mechanism (2), an intermittent transmission compound gear train (3), a foil compaction and material return mechanism (4), a base (5), and a foil end tensioning mechanism (6). The flexible horizontal progressive foil mechanism (1) is arranged on the base (5) and is bolted to the base (5) through a first sliding rail (104). The flexible vertical forming mechanism (2) is arranged on the flexible horizontal progressive foil mechanism (1) and is bolted to the horizontal sliding block connecting piece a (105a) through a second sliding rail a (208a), and can move horizontally with the flexible horizontal progressive foil mechanism (1). The intermittent transmission compound gear train (3) can realize the horizontal and vertical movement of the flexible horizontal progressive foil mechanism (1) and the flexible vertical forming mechanism (2). The foil compaction and material return mechanism (4) is arranged on the base (5) and is bolted to the base (5) through a third sliding rail (408), and can compact the aluminum foil after folding to form a crease and return the finished product. The foil end tensioning mechanism (6) is arranged on the base (5) and provides a certain tension to the aluminum foil. The parts in the flexible horizontal progressive foil mechanism (1), the flexible vertical forming mechanism (2), and the intermittent transmission compound gear train (3) are symmetrical about the metal foil, with the upper part named a and the lower part named b.

[0034] Take the complete process of long metal foil feeding, folding, and material returning as an example. The worker places the long metal foil on the fixed part (601), folds it in advance at one crease, and places it on the outside folding knife a (205a), and rotates the fourth shaft (308a).

[0035] To achieve the folding function, the incomplete gear a (307a) rotates counterclockwise, the incomplete gear b (307b) rotates clockwise, and the keyway is 90° when assembled, that is, at 1 / 4 of a period, the incomplete gear a (307a) engages with the first gear a (302a), driving the first shaft a (301a), the roller fixing part a (303a), and the roller a (304a) to rotate, thereby lifting the vertical sliding block connector a (203a), at 3 / 4 of a period, the incomplete gear b (307b) engages with the first gear b (302b), driving the first shaft b (301b), the roller fixing part b (303b), and the roller b (304b) to rotate, thereby lifting the vertical sliding block connector b (203b).

[0036] To achieve the function of compressing the folded aluminum foil, the cam a (305a) rotates counterclockwise and the cam b (305b) rotates clockwise, and the relative angle of the keyway is zero when assembled. Due to the opposite direction, the folding knife folding work of cam a (305a) corresponds to the feeding work of cam b (305b). In the static stage, the cam does not work, and there is a certain gap with the vertical sliding block connector (203). The first spring (102) applies a left spring force, making the folding knife (205) rest on the stop block, achieving the compression feeding function.

[0037] As shown in the above figure, the movement state of the cam and the incomplete gear corresponding to the different positions of the folding knife. In the initial position, the incomplete gear a (307a), the incomplete gear b (307b) is not engaged, the cam a (305a), the cam b (305b) is in the horizontal mechanism does not work static stage; In 1 / 8, the incomplete gear a (307a), the incomplete gear b (307b) is not engaged, the cam a (305a) is in the folding knife folding stage in the push stage, the cam b (305b) is in the feeding stage in the push stage, in this process, the two folding knives (205) move a distance to the right at the same time; In 2 / 8, the incomplete gear a (307a) is engaged, the incomplete gear b (307b) is not engaged, the cam a (305a) is in the folding knife folding stage in the static stage, the cam b (305b) is in the feeding stage in the static stage, in this process, the upper folding knife moves up and the lower folding knife does not move; In 3 / 8, the incomplete gear a (307a) is engaged, the incomplete gear b (307b) is not engaged, the cam a (305a) is in the folding knife folding stage in the static stage, the cam b (305b) is in the feeding stage in the static stage and completes the return, in this process, the lower folding knife moves to the left, and the upper folding knife does not move; In 4 / 8, the incomplete gear a (307a) is engaged, the cam a (305a), the cam b (305b) is in the horizontal mechanism does not work static stage, does not work, in this process, due to the action of the spring, the upper and lower folding knives are in close contact with the stop block in turn. The above is the first half of the cycle of the mechanism, the second half of the cycle is similar and will not be described here, and the whole cycle can fold a crease.

[0038] The folded long strip metal foil is stored in the stop block (401), and the push plug (404) extrudes the third spring (405). Since the lower end of the handle (402) is clamped on the third slide rail (408), the whole body cannot move to the left. When the long strip metal foil folding and compression is completed, the worker rotates and pushes the handle (402) to the left. The lower end of the handle is dislocated with the third slide rail (408), and the third slide block (409) moves to the left. At this time, the plug (404) is slowly moved to the left by the elastic force of the third spring (405) slower than the stop block (401), which can push out the aluminum foil inside the stop block (401). At the same time, the stop block (401) moves to the left with the third slide block (409) to leave a space for the aluminum foil to discharge.

7. The intermittent flexible long strip metal foil folding mechanism according to claim 1, characterized in that: The foil compaction and unloading mechanism (4) includes a stop block (401), a handle (402), a torsion spring (403), a plunger (404), a third spring (405), a bolt (406), a limiting block (407), a third slide rail (408), a third slider (409), a third connecting plate (410), and a hinge (411). The stop block (401) has a U-shaped cross-section and is hollow inside. It is bolted to the third connecting plate (410). The folded long strip of metal foil will continuously enter the cavity. The first handle protrusion (402-1) is a protrusion for the worker to grip. The worker grips the first handle protrusion (402-1) and rotates it. The second handle protrusion (402-2) is used to limit the slider. Since the long strip of metal foil will exert a certain force on the plunger (404) when it enters the stop block (401), the entire unloading mechanism will move to the left. The second handle protrusion (402-2) pushes against the stop block. The third slide rail (408) is held in place to prevent it from moving to the left. The torsion spring (403) is set in the groove of the handle (402) and the stop block (401). The plunger (404) slides relative to the stop block (401). When the folded aluminum foil enters the stop block (401), it will push the plunger (404) to move to the left relative to the stop block. The plunger boss (404-b) has a hole for placing the third spring (405). The third spring (405) will give the plunger boss (404-b) a force to the right. In this way, the folded metal foil will be subjected to a force to the right during storage, thereby achieving a certain compaction effect. The third connecting plate (410) is set on the third slider (409) by bolts. The third slider (409) is set on the third slide rail (408) and slides relative to it. The third slide rail (408) is connected to the base (5) by bolts and is parallel to the first slide rail (104).
