[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. 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 scope of protection of the present application.

[0030] Referring to Figures 1 to 11 : The utility model provides an automatic broken stack device for narrow material processing, including first conveying belt 1 and second conveying belt 2 that distribute and reverse drive up and down, the output of first conveying belt 1 is provided with broken unit, and the output of second conveying belt 2 is provided with stacking unit;The output of first conveying belt 1 is arranged in the vertical direction movement and is provided with first material supporting platform 3a and second material supporting platform 3b of lifting material receiving frame 3, second material supporting platform 3b can change the interval with first material supporting platform 3a along the horizontal movement of first conveying belt 1 conveying direction, when lifting material receiving frame 3 is located at the top, the surface of first material supporting platform 3a and second material supporting platform 3b is flush with the surface of first conveying belt 1 and first material supporting platform 3a is attached to first conveying belt 1, when lifting material receiving frame 3 is located at low position, first material supporting platform 3a and second material supporting platform 3b are lower than the surface of second conveying belt 2;The output of first conveying belt 1 is provided with pressing plate 4, and the gap between pressing plate 4 and first material supporting platform 3a is same with the thickness of the plate, and the working end of broken unit is aligned with the top end of pressing plate 4.

[0031] When the utility model processes narrow material, first conveying belt 1 transports the narrow material to be processed to the output horizontally, at this time, lifting material receiving frame 3 is at the top position, the surface of first material supporting platform 3a and second material supporting platform 3b is flush with the surface of first conveying belt 1 and first material supporting platform 3a is attached to first conveying belt 1, and the narrow material continuously transports through the gap between pressing plate 4 and first material supporting platform 3a;When the narrow material is transported to the preset broken length, the top end of the narrow material moves to second material supporting platform 3b;The staff can adjust the interval between second material supporting platform 3b and first material supporting platform 3a before processing to adapt the broken requirement of the current narrow material;Then, the working end of broken unit is aligned with the top end of pressing plate 4, and the force is applied to the narrow material to complete the broken work; Figures 8 to 11As shown, after the folding is completed, the first supporting table 3a and the second supporting table 3b support the two ends of the folded narrow material, and then the lifting material receiving frame 3 moves downward to the low position, at this time, the first supporting table 3a and the second supporting table 3b are lower than the surface of the second conveying belt 2, the folded narrow material falls onto the second conveying belt 2, and the second conveying belt 2 conveys it to the stacking unit at the output end, and finally completes the automatic stacking of the narrow material. The folding unit and the stacking unit in the embodiment are both relatively mature prior art, which are not shown in the figure; the first conveying belt 1, the second conveying belt 2, the lifting material receiving frame 3, the pressing plate 4 and the folding unit in the embodiment are cooperated to realize the automatic and consecutive operation of the narrow material cutting, folding and stacking processes, completely replace the step-by-step operation mode of manual operation and semi-automatic equipment, and significantly improve the production efficiency, which can be adapted to large-batch production scenarios; the second supporting table 3b in the embodiment can be horizontally moved to adjust the distance with the first supporting table 3a, which can flexibly adapt to the folding processing requirements of narrow materials of different specifications and ensure the application range of the equipment; the gap between the pressing plate 4 and the first supporting table 3a in the embodiment is accurately matched with the thickness of the plate, and the working end of the folding unit is aligned with the top end of the pressing plate 4, which avoids the edge deformation and cracking of the narrow material caused by the traditional rigid impact folding, and is especially suitable for processing of thin-walled and high-precision narrow materials, and effectively reduces the material damage rate.

[0032] In order to realize the lifting movement of the lifting material receiving frame 3 and ensure the accuracy of the reset, the following features are specifically provided: A fixed seat 3c is arranged on one side of the second conveying belt 2, two parallel and equal length rotating arms 3c1 are rotatably installed at the same height position of the fixed seat 3c, connecting shafts 3c2 are arranged at both ends of the fixed seat 3c and are horizontally arranged perpendicular to the length direction of the fixed seat 3c, the fixed seat 3c is rotatably installed on the fixed seat 3c through the rotating arms 3c1, synchronous wheels 3c3 are coaxially installed on the two connecting shafts 3c2 on the fixed seat 3c, the synchronous wheels 3c3 are drivingly connected through a synchronous belt 3c4, and a rotating driver 3c5 for driving the fixed seat 3c to rotate around the connecting shaft 3c2 is arranged on the fixed seat 3c; the connecting shafts 3c2 at the other ends of the rotating arms 3c1 are rotatably installed at the same horizontal height of the lifting material receiving frame 3.

[0033] A limiting block 3c6 is installed on the fixed seat 3c and located on the rotating path of the rotating arm 3c1, when the rotating arm 3c1 rotates to abut against the limiting block 3c6, the first supporting table 3a of the lifting material receiving frame 3 is flush with the surface of the first conveying belt 1.

[0034] As Figures 5 to 7As shown, the rotating driver 3c5 on the fixed seat 3c drives the rotating arm 3c1 to rotate around the connecting shaft 3c2 on the fixed seat 3c; because the coaxial synchronous wheels 3c3 are installed on the connecting shaft 3c2 at both ends of the fixed seat 3c, and the two synchronous wheels 3c3 are drivingly connected through the synchronous belt 3c4, the two rotating arms 3c1 are synchronously rotated around the connecting shaft 3c2, respectively, the other end of the rotating arm 3c1 is drivingly connected with the lifting material receiving frame 3 through the connecting shaft 3c2, and under the support and transmission of the rotating arm 3c1, the lifting material receiving frame 3 realizes stable change of height position; when the lifting material receiving frame 3 needs to be lifted and reset, the rotating arm 3c1 continuously rotates until it abuts against the limiting block 3c6 on the fixed seat 3c, at this time, the limiting block 3c6 limits the rotating arm 3c1 from continuing to rotate, and the lifting material receiving frame 3 stops lifting, and the first material supporting table 3a is just flush with the surface of the first conveying belt 1, and the precise reset is completed; when it needs to be lowered, the rotating driver 3c5 is reversely driven to reversely rotate the rotating arm 3c1, and the lifting material receiving frame 3 is lowered to the low position. The rotating driver 3c5 in the embodiment can be a servo motor or the like; the synchronous rotating action of the two parallel and equal-length rotating arms 3c1 in the embodiment makes the lifting process of the lifting material receiving frame 3 stable and without inclination, ensures that the first material supporting table 3a and the second material supporting table 3b always keep balance, and stably moves the narrow material, the length of the rotating arm 3c1 cooperates with the existence of the limiting block 3c6 to ensure the precision of the lifting material receiving frame 3 after reset, without complex parameter adjustment, and is convenient and efficient.

[0035] In order to facilitate the broken narrow material on the lifting material receiving frame 3 to fall on the second conveying belt 2, the following features are specifically provided: The second conveying belt 2 is provided with an avoiding gap 2a avoiding the first material supporting table 3a, and the first material supporting table 3a moves to the lower side of the second conveying belt 2 through the avoiding gap 2a.

[0036] As shown in Figure 3 and Figure 11 The second conveying belt 2 in the embodiment can be a drum conveying belt, when the lifting material receiving frame 3 moves downward, the position-fixed first material supporting table 3a passes through the avoiding gap 2a on the second conveying belt 2, which ensures that the narrow material between the first material supporting table 3a and the second material supporting table 3b can fall on the second conveying belt 2 and be separated from the first material supporting table 3a and the second material supporting table 3b, and the broken narrow material is conveyed to the stacking unit by the second conveying belt 2.

[0037] In order to change the distance between the first material supporting table 3a and the second material supporting table 3b, the following features are specifically provided: The second material supporting table 3b is slidingly installed on the lifting material receiving frame 3, and the bottom of the second material supporting table 3b is screw-installed with a fixing bolt 3b1 for locking the second material supporting table 3b.

[0038] As shown in Figure 7As shown, the embodiment adopts the combination structure of sliding installation and fixed bolt 3b1 locking to realize the quick and convenient adjustment of the distance between the first supporting table 3a and the second supporting table 3b.

[0039] In order to accurately control the breaking position of the narrow material, the following features are specifically set: The second supporting table 3b is provided with a material blocking plate 3b2 at the end away from the first supporting table 3a.

[0040] As shown, Figures 5 to 7 As shown, the embodiment transports the narrow material to be processed by the first conveying belt 1, and after the narrow material passes through the gap between the pressing plate 4 and the first supporting table 3a, it continues to move towards the second supporting table 3b until the front end of the narrow material abuts against the material blocking plate 3b2 at the end of the second supporting table 3b away from the first supporting table 3a; At this time, the narrow material reaches the preset breaking length. The embodiment can also set a sensor on the material blocking plate 3b2, which automatically stops the first conveying belt 1 and starts the breaking unit after the narrow material contacts the material blocking plate 3b2.

[0041] In order to guide the movement of the narrow material, the following features are specifically set: The upper surfaces of the first supporting table 3a and the second supporting table 3b are slidingly installed with two side limiting plates 3a1, the side limiting plates 3a1 are rotatably connected to the adjusting bolts 3a2 outside, the adjusting bolts 3a2 are screw installed on both sides of the first supporting table 3a and the second supporting table 3b, and the axis of the adjusting bolt 3a2 is horizontally arranged perpendicular to the conveying direction of the first conveying belt 1.

[0042] The two sides of the first conveying belt 1 are provided with guide baffles 1a flush with the side limiting plates 3a1.

[0043] As shown, Figures 5 to 8 As shown, the embodiment can rotate the adjusting bolts 3a2 on both sides of the first supporting table 3a and the second supporting table 3b according to the width specification of the narrow material to be processed, so that the side limiting plates 3a1 slide along the upper surfaces of the first supporting table 3a and the second supporting table 3b until the distance between the two side limiting plates 3a1 is adapted to the width of the narrow material; At the same time, ensure that the guide baffles 1a on both sides of the first conveying belt 1 are flush with the side limiting plates 3a1 to form a continuous guide channel, which provides protection for the subsequent movement and accurate breaking of the narrow material.

[0044] In order to be able to change the height position of the pressing plate 4 according to the thickness of the narrow material, the following features are specifically set: The output end of the first conveying belt 1 is provided with a vertical mounting bracket 4a, the pressing plate 4 is provided with a plurality of vertical guide rods 4b, the guide rods 4b are inserted and mounted on the mounting bracket 4a, the mounting bracket 4a is provided with a linear actuator 4c, and the working end of the linear actuator 4c is arranged in a vertical direction and fixedly connected with the pressing plate 4.

[0045] AsFigure 4 As shown, according to the thickness specification of the narrow material to be processed, the linear driver 4c on the output end mounting frame 4a of the first conveying belt 1 is started, the working end of the linear driver 4c moves in the vertical direction, and the pressing plate 4 fixedly connected thereto is synchronously lifted; it is ensured that the narrow material can pass through the gap between the pressing plate 4 and the first supporting table 3a, and the narrow material can be fixed during breaking; when the pressing plate 4 moves, the several vertical guide rods 4b arranged on the surface thereof slide along the corresponding mounting holes of the mounting frame 4a, and play a guiding and limiting role.

[0046] As shown, in order to facilitate the movement of the narrow material under the clamping of the pressing plate 4 and the first supporting table 3a, the following features are specifically provided: Figure 4 A plurality of pressing rollers 4d are rotatably installed on the pressing plate 4, the rotating shafts of the pressing rollers 4d are arranged horizontally and perpendicular to the conveying direction of the first conveying belt 1, and the lower surfaces of the pressing rollers 4d protrude from the lower surface of the pressing plate 4 and are attached to the upper side of the plate.

[0047] The whole working principle of the present application is that, during the processing of the narrow material, the first conveying belt 1 horizontally conveys the narrow material to be processed to the output end, and the narrow material is continuously conveyed through the gap between the pressing plate 4 and the first supporting table 3a; when the narrow material is conveyed to the preset breaking length, the top end of the narrow material moves to the second supporting table 3b; then an acting force is applied to the narrow material to complete the breaking operation; after the breaking is completed, the lifting material receiving frame 3 moves downward to the low position, and the broken narrow material falls onto the second conveying belt 2, which conveys it to the stacking unit at the output end, and finally completes the automatic stacking of the narrow material.
