Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0043] At present, metal cans are generally assembled by hinged lids and can bodies. In the process of can body processing, many steps of the can body processing technology cannot be carried out on the production line. After one process is completed manually, it needs to be transferred to the next station for manual processing, which is time-consuming and labor-intensive, and has low production efficiency. At the same time, the multiple processes required to process the sheet into the can body are generally controlled by multiple drive mechanisms, which is costly and inconvenient to synchronize.

[0044] In order to solve the above problems, this embodiment discloses a small bone buckling machine, the structure of which is as follows: Figures 1 to 7 As shown, the small buckle machine includes a frame 103, a feeding mechanism 100, a driving mechanism 102, a feeding mechanism 101 installed at one end of the feeding mechanism 100, a first folding hook mechanism 200, a first arc pressing mechanism 300, a can body discount mechanism 400 and an interface forming mechanism 500 arranged in sequence from one end to the other end of the feeding mechanism 100, the first folding hook mechanism 200 and the first arc pressing mechanism 300 are respectively located on one side of the feeding mechanism 100, and the other side of the feeding mechanism 100 is provided with a second folding hook mechanism 209 and a second arc pressing mechanism 308, and the feeding mechanism 100, the driving mechanism 102, the feeding mechanism 101, the first folding hook mechanism 200, the first arc pressing mechanism 300, the can body discount mechanism 400, the interface forming mechanism 500, the second folding hook mechanism 209 and the second arc pressing mechanism 308 are all installed on the frame 103;

[0045] The feeding mechanism 100 is used to transport the material sheet from one end of the feeding mechanism 100 to the other end, the feeding mechanism 101 is used to load the material sheet to the feeding mechanism 100, the first folding hook mechanism 200 and the second folding hook mechanism 209 are used to fold the two ends of the material sheet into a first hook structure and a second hook structure respectively, the first arc pressing mechanism 300 and the second arc pressing mechanism 308 are used to press the two ends of the material sheet into an arc structure respectively, the can body discount mechanism 400 is used to bend the material sheet into a can body and buckle the hook structures at both ends into a buckling structure, the interface forming mechanism 500 is used to press the buckling structure of the can body, and the driving mechanism 102 is used to drive the feeding mechanism 100, the first folding hook mechanism 200, the first arc pressing mechanism 300, the second folding hook mechanism 209, the second arc pressing mechanism 308, the can body discount mechanism 400 and the interface forming mechanism 500 to perform the above processing actions simultaneously.

[0046] In this embodiment, the driving mechanism 102 is composed of at least a motor, a pulley, a belt, a plurality of rotating shafts, gears, a chain and a cam. Figure 2It can be seen that the driving mechanism 102 is roughly divided into three parts. The first part is a structure composed of a motor, a pulley and a belt; the second part is located below the can body discount mechanism 400 and the interface forming mechanism 500, and is composed of a rotating shaft, gears and a number of cams; the third part is located below the first folding hook mechanism 200 and the first arc pressing mechanism 300, and is composed of a rotating shaft and gears. The second part and the third part are synchronously driven through the cooperation of gears and chains; the second part and the can body discount mechanism 400, the interface forming mechanism 500 and other structures are synchronously driven through the relevant linkage structures in the above-mentioned mechanisms; the third part and the first folding hook mechanism 200 and the second folding hook mechanism 209 are synchronously driven through the cooperation of gears and chains, and the first arc pressing mechanism 300 and the second arc pressing mechanism 308 are synchronously driven through the cooperation of gears set on the folding hook rotating shaft 202, gears on the arc pressing rotating shaft 302 and chains. By simply configuring the wheel diameter, angle, direction of the cam mentioned above and the internally related linkage structure within the above-mentioned mechanism, a single motor can be used to drive the feeding mechanism 100 to transport the material sheets while all the above-mentioned mechanisms perform various processing actions at the same time, which effectively reduces the cost and achieves a higher synchronization rate.

[0047] It should be noted that the feeding mechanism 100 in this embodiment at least includes a feeding channel and a feeding mechanism for reciprocatingly pushing the sheet. Figure 2 And its principle belongs to the prior art, and will not be repeated here.

[0048] Next, the structure and principle of each of the above-mentioned mechanisms will be further explained.

[0049] Specifically, the first folding hook mechanism 200 includes a first folding hook frame 201, a folding hook shaft 202 rotatably arranged on the first folding hook frame 201, a first folding hook swing arm 203 and a second folding hook swing arm 204, the folding hook shaft 202 is drivingly connected to the output end of the driving mechanism 102, and the folding hook shaft 202 is coaxially provided with a first folding hook cam 205 and a second folding hook cam 206; one end of the first folding hook swing arm 203 away from the feeding mechanism 100 abuts against the first folding hook cam 205, and the other end of the first folding hook swing arm 203 is provided with a first A folding hook pressure block 207, and a first folding hook block 208 is provided at one end of the second folding hook swing arm 204 close to the feeding mechanism 100, and the other end of the second folding hook swing arm 204 abuts against the second folding hook cam 206; when the cam surface of the first folding hook cam 205 abuts against one end of the first folding hook swing arm 203, the cam surface of the second folding hook cam 206 abuts against the other end of the second folding hook swing arm 204, the first folding hook pressure block 207 presses one end of the material sheet against the first folding hook frame 201, and at the same time the first folding hook block 208 folds one end of the material sheet into a first hook-shaped structure.

[0050] The second folding hook mechanism 209 includes a second folding hook frame 210, a third folding hook swing arm 211 and a fourth folding hook swing arm 212 rotatably arranged on the second folding hook frame 210, one end of the folding hook shaft 202 passes through the first folding hook frame 201 and is rotatably connected to the second folding hook frame 210, and the folding hook shaft 202 is coaxially provided with a third folding hook cam 213 and a fourth folding hook cam 214; one end of the third folding hook swing arm 211 away from the feeding mechanism 100 abuts against the third folding hook cam 213, and the other end of the third folding hook swing arm 211 is provided with a second folding hook pressing block 21 5. A second folding hook block 216 is provided at one end of the fourth folding hook swing arm 212 away from the feeding mechanism 100, and the other end of the fourth folding hook swing arm 212 abuts against the fourth folding hook cam 214; when the cam surface of the third folding hook cam 213 abuts against one end of the third folding hook swing arm 211, the cam surface of the fourth folding hook cam 214 abuts against the other end of the fourth folding hook swing arm 212, the second folding hook pressing block 215 presses one end of the material sheet against the second folding hook frame 210, and the second folding hook block 216 folds one end of the material sheet into a second hook-shaped structure that is symmetrical with the center of the first hook-shaped structure.

[0051] from Figure 3 and Figure 4 It can be seen that when the driving mechanism 102 drives the folding hook shaft 202 to rotate, the cam surfaces of the first folding hook cam 205 and the second folding hook cam 206 respectively and simultaneously abut against the first folding hook swing arm 203 and the second folding hook swing arm 204, and the first folding hook pressing block 207 and the first folding hook block 208 form corresponding shapes after being pressed together, thereby realizing the folding of one end of the sheet, thereby forming a shape as shown in FIG. Figure 8 Similarly, the second hook mechanism 209 realizes folding the other end of the sheet into a Figure 8 The second hook-shaped structure shown, and the process and principle of the second folding hook mechanism 209 are similar to those of the first folding hook mechanism 200, which will not be repeated here.

[0052] In addition, this embodiment also provides rollers at the position where the first fold hook swing arm 203 contacts the first fold hook cam 205, the position where the second fold hook swing arm 204 contacts the second fold hook cam 206, the position where the third fold hook swing arm 211 contacts the third fold hook cam 213, and the position where the fourth fold hook swing arm 212 contacts the fourth fold hook cam 214 to reduce the friction with the cam and increase the service life.

[0053] Furthermore, the first arc pressing mechanism 300 includes a first arc pressing frame 301, an arc pressing shaft 302 rotatably arranged on the first arc pressing frame 301, a first arc pressing cam 303 coaxially arranged on the arc pressing shaft 302, a first cam slider 304 sleeved on the first arc pressing cam 303, a first arc pressing slider 305 slidably arranged on the first arc pressing frame 301, and a first arc pressing block 306 arranged at the upper end of the first arc pressing slider 305; the arc pressing shaft 302 is drivingly connected to the output end of the driving mechanism 102, the first arc pressing slider 305 is provided with a first arc pressing slide hole 307, and the first cam slider 304 is movable left and right in the first arc pressing slide hole 307.

[0055] from Figure 3 , Figure 4 , Figure 5 It can be seen that the hook shaft 202 drives the arc pressing shaft 302 to rotate synchronously through gears and chains. When the first arc pressing cam 303 rotates, the first cam slider 304 will swing along the trajectory of the first arc pressing cam 303. However, since the first arc pressing sliding hole 307 on the first arc pressing slider 305 limits the first cam slider 304 in the up and down directions, the first cam slider 304 can only slide in the horizontal direction relative to the first arc pressing slider 305. This forms the first arc pressing slider 305 driving the first arc pressing slider 305 to slide up and down relative to the first arc pressing frame 301, and during this period, the first arc pressing block 306 is driven to press one end of the sheet into Fig. 9 Similarly, the second arc pressing mechanism 308 realizes pressing the other end of the sheet into Fig. 9 The arc structure shown, the process and principle of the second arc pressing mechanism 308 are similar to those of the first arc pressing mechanism 300, and will not be repeated here.

[0056] Furthermore, the can body discount mechanism 400 includes a can body forming jig 401, a forming jig lifting mechanism 402, a first clamping mechanism 403 and a second clamping mechanism 413. The input end of the forming jig lifting mechanism 402 is drivingly connected to the output end of the driving mechanism 102. The can body forming jig 401 is installed at the output end of the forming jig lifting mechanism 402 and is connected to the other end of the feeding mechanism 100. The input end of the first clamping mechanism 403 and the input end of the second clamping mechanism 413 are drivingly connected to the output end of the driving mechanism 102 respectively. The first clamping mechanism 403 and the second clamping mechanism 413 are respectively used to bend the sheet into a can body and buckle the hook structures at both ends into a buckling structure.

[0057] In this embodiment, the structure of the can body forming jig 401 can refer to Figure 6 , which is a long columnar structure placed at an angle. After being processed by the aforementioned hook folding mechanism and arc pressing mechanism, the sheet enters the can body forming jig 401 from the end of the feeding channel; then the first clamping mechanism 403 and the second clamping mechanism 413 are respectively engaged with the can body forming jig 401, bending the sheet into a can body and buckling the hook structures at both ends into a buckled structure.

[0058] Specifically, the first clamping mechanism 403 includes a first clamping shaft 414, a first clamping cam 404, a first clamping slide arm 405, a first clamping swing arm 406, a second clamping slide arm 407, a second clamping swing arm 408, a third clamping swing arm 409, a fourth clamping swing arm 410 and a clamping mold 411, the first clamping shaft 414 is drivingly connected to the output end of the driving mechanism 102, the first clamping cam 404 is coaxially arranged on the first clamping shaft 414, one end of the first clamping slide arm 405 is movably connected to the output end of the driving mechanism 102, one end surface of the first clamping cam 404 is provided with a first cam groove 412, non-two end positions of the first clamping slide arm 405 are slidably connected to the first cam groove 412, and the other end of the first clamping slide arm 405 and one end of the first clamping swing arm 406 can be moved left and right The first clamping slide 405 is connected to the frame 103 for sliding rotation and is connected to the frame 103 for sliding up and down; the first clamping swing arm 406 is connected to the frame 103 for rotation at non-end positions, one end of the second clamping slide 407 is connected to the other end of the first clamping swing arm 406 for sliding left and right rotation, the other end of the second clamping slide 407 is connected to one end of the second clamping swing arm 408 for rotation and the second clamping slide 407 is connected to the frame 103 for sliding up and down, the other end of the second clamping swing arm 408 is connected to one end of the third clamping swing arm 409 for sliding left and right rotation, the third clamping swing arm 409 is connected to the frame 103 for rotation at non-end positions, the other end of the third clamping swing arm 409 is connected to one end of the fourth clamping swing arm 410 for rotation, and the other end of the fourth clamping swing arm 410 is connected to the clamping mold 411 for rotation.

[0059] from Figure 6 and Figure 7 It can be seen that the first clamping shaft 414 is driven to rotate by the driving mechanism 102, and the linkage structure formed by the first clamping cam 404, the first clamping slide arm 405, the first clamping swing arm 406, the second clamping slide arm 407, the second clamping swing arm 408, the third clamping swing arm 409 and the fourth clamping swing arm 410 drives the clamping mold 411 to perform a clamping action to form the following Fig.11 shape shown; similarly, the structure of the first clamping mechanism 403 and the structure of the second clamping mechanism 413 are symmetrically arranged about the can body forming jig 401; that is, except for the shape of the clamping mold 411, the process and principle of the second clamping mechanism 413 are similar to those of the first clamping mechanism 403, which will not be repeated here.

[0060] Further, such as Figure 8As shown, the interface molding mechanism 500 includes an interface molding mold 501, an interface molding cam 502 and a molding mold lifting slide 503. The interface molding cam 502 is drivingly connected to the output end of the driving mechanism 102 (or coaxially arranged on the first clamping shaft 414), one end of the molding mold lifting slide 503 is rotatably mounted on the interface molding cam 502 and the molding mold lifting slide 503 is slidably connected to the frame 103 up and down, and the interface molding mold 501 is installed at the other end of the molding mold lifting swing arm and is directly below the can body molding jig 401.

[0061] In this embodiment, after the can body is folded by the can body folding mechanism 400, it moves to the end of the can body forming jig 401. When it reaches the top of the interface forming mold 501, the interface forming cam 502 pushes the forming mold lifting slide arm 503 upward, and the forming mold squeezes the corresponding position of the can body, thereby forming Fig.12 The structure shown completes the processing of the can body.

[0062] In summary, a small bone buckling machine in this embodiment is provided with a feeding mechanism 100, a driving mechanism 102, a feeding mechanism 101, a first folding hook mechanism 200, a first arc pressing mechanism 300, a second folding hook mechanism 209, a second arc pressing mechanism 308, a can body discount mechanism 400 and an interface forming mechanism 500. When in use, the feeding mechanism 101 puts the material into the feeding mechanism 100, and the driving mechanism 102 is started at the same time, and the material is transported, folded, arc pressed, discounted and pressed into shape in sequence according to the frequency set by the driving mechanism 102.

[0063] Compared with the prior art, the utility model can fully automatically process the material sheets into the can bodies, and only needs to be realized through a set of driving mechanisms 102, which is more efficient, less costly and more convenient for synchronization.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
