Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to an aluminum foil bag cutting assembly capable of high-precision positioning. Background Technique

[0002] Before making the aluminum foil bag, it is necessary to cut the aluminum foil bag coil into an appropriate width so as to facilitate the introduction of the aluminum foil bag coil into the bag-making equipment for processing. According to different widths, aluminum foil bags of different specifications are produced. For the existing equipment for cutting the aluminum foil bag coil, since the distance between its cutting knives is fixed, the width of the produced aluminum foil bag coil is fixed. When it is necessary to produce aluminum foil bag coils of other widths, only the equipment can be replaced, thus reducing the production efficiency.

[0003] Based on the above situation, in the prior art, the patent with the publication number of CN219133393U discloses a slitting mechanism for aluminum foil bag production, including two columns. The tops of the two columns are fixedly connected with a cover plate. A lifting mechanism is arranged near the center of the bottom of the cover plate. The bottom of the lifting mechanism is connected with a support plate. The bottom of the support plate is connected with an adjustment box. An adjustment mechanism is arranged inside the adjustment box, and two slitting knives are installed on the adjustment mechanism; the above slitting mechanism drives the first conical gear to rotate through the second motor, drives the bidirectional lead screw to rotate through the transmission of the first conical gear, and limits the moving range of the strip groove so that the nut slides towards the middle or both sides on the outer wall of the bidirectional lead screw, and the nut drives the connecting block and the slitting knife to translate, so that the distance between the two slitting knives changes, thereby completing the adjustment of the cutting distance of the two slitting knives and enabling slitting of different specifications and sizes.

[0004] However, the slitting mechanism in this patent still has some deficiencies in combination with the actual situation. The distance adjustment between the two slitting knives of the above slitting mechanism is not free enough, and only two width specifications of aluminum foil bag coils can be cut, which reduces the practicability of the above slitting mechanism to a certain extent. At the same time, the above slitting mechanism also has the problem of insufficient positioning accuracy. When adjusting the distance, the position of the cutting line cannot be visually observed.

Detailed implementation manners

[0021] The following combines the drawings with related embodiments to illustrate the implementation manners of the present utility model. The implementation manners of the present utility model are not limited to the following embodiments, and the relevant necessary components involved in the present utility model should be regarded as well-known technologies in the technical field, which can be known and mastered by those skilled in the technical field.

[0022] As Figures 1 to 4 shown, the present utility model provides a technical solution: an aluminum foil bag cutting component capable of high-precision positioning, including a frame 1, a fixedly connected mounting frame 12 is provided in the middle of the frame 1, a cutting table 11 connected to the frame 1 is provided below the mounting frame 12, clamping and conveying components 2 are fixedly connected to the feeding end and the discharging end of the frame 1 respectively, a positioning and adjusting component 5 is provided below the mounting frame 12, the positioning and adjusting component 5 includes a first adjusting component 51 and a second adjusting component 52, the first adjusting component 51 and the second adjusting component 52 are parallel to each other and movably connected to the mounting frame 12, pressing components 4 are fixedly connected below the first adjusting component 51 and the second adjusting component 52 respectively, a cutting component 3 is fixedly connected below the pressing component 4, and a laser locator 6 is fixedly connected above the pressing component 4 and the cutting component 3.

[0023] The utility model realizes high-precision positioning of the cutting component 3 when cutting the aluminum foil bag coil. The first adjusting component 51 and the second adjusting component 52 are screw nut transmission mechanisms. The first adjusting component 51 and the second adjusting component 52 are respectively connected to the cutting component 3. The first adjusting component 51 and the second adjusting component 52 can respectively adjust the position of the cutting component 3 on the surface of the aluminum foil bag coil, so that the cutting component 3 can achieve high-precision positioning on the surface of the aluminum foil bag coil, can accurately control the cutting width of the aluminum foil bag coil, and can cut three aluminum foil bag coils of different widths. The laser locator 6 projects a straight laser line On the surface of the aluminum foil bag, the cutting path of the cutting component 3 is displayed. The cutting width of the aluminum foil bag coil can be adjusted by measuring the width between the laser lines, thereby increasing the accuracy of cutting. The first clamping and transporting components 21 and the second clamping and transporting components 22 arranged at both ends of the frame 1 can clamp and transport the aluminum foil bag coil to avoid the deviation of the aluminum foil bag coil during the cutting process. The pressing components 4 are respectively arranged on both sides of the cutting component 3, which can press the aluminum foil bag coil during cutting, so that the aluminum foil bag coil is close to the surface of the cutting table 11, avoiding the deviation of the aluminum foil bag coil, and further increasing the accuracy of cutting.

[0024] like Figure 1 and Figure 3 As shown, as a preferred embodiment of the utility model, the clamping and conveying assembly 2 includes an upper clamping roller 23 and a lower clamping roller 24, a gear 25, a chain 26 and a driving motor 27 which are arranged in parallel above and below, and the two ends of the upper clamping roller 23 and the lower clamping roller 24 are respectively movably connected to the frame 1, and the ends of one end of the upper clamping roller 23 and the lower clamping roller 24 pass through the side wall of the frame 1 and are fixedly connected to the gear 25, and the gears 25 are connected by a chain 26 for transmission, and the power output shaft of the driving motor 27 is connected to the lower clamping roller 24 and connected to one end of the gear 25.

[0025] The clamping and conveying components 2 are symmetrically arranged at the feed end and the discharge end of the equipment. The first clamping and conveying component 21 is arranged at the feed end, and the second clamping and conveying component 22 is arranged at the discharge end. The first clamping and conveying component 21 and the second clamping and conveying component 22 are the same in structure and components, and are both composed of an upper clamping roller 23 and a lower clamping roller 24, a gear 25, a chain 26 and a driving motor 27.

[0026] The clamping and conveying assembly 2 includes an upper clamping roller 23 and a lower clamping roller 24 which are arranged in parallel up and down. Both ends of the upper clamping roller 23 and the lower clamping roller 24 can be movably connected to the frame 1 through bearings (not shown). One end of the upper clamping roller 23 and the lower clamping roller 24 passes through the side wall of the frame 1 and is fixedly connected to a gear 25. The gears 25 are connected to each other through a chain 26 to form a gear transmission system. When the driving motor 27 is started, the power of the driving motor 27 drives the lower clamping roller 24 to rotate through the power output shaft. Since the gears 25 are connected through the chain 26, the gear 25 connected to the upper clamping roller 23 will also rotate with the transmission of the chain 26, thereby driving the upper clamping roller 23 to rotate. When the upper clamping roller 23 and the lower clamping roller 24 rotate at the same time, the aluminum foil bag coil will be clamped and conveyed in the feeding direction, thereby effectively preventing the aluminum foil bag coil from deflecting or slipping during the conveying process, so that the aluminum foil bag coil can be stably clamped and conveyed during the entire processing process.

[0027] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the utility model, the first adjustment component 51 includes a first motor 511, a first lead screw 512, a first threaded sleeve 513, and a first telescopic electric cylinder 514. One end of the first lead screw 512 is movably connected to the mounting frame 12, and the other end of the first lead screw 512 is transversely mounted on the mounting frame 12 and connected to the first motor 511 arranged outside the mounting frame 12. The first threaded sleeve 513 is movably sleeved on the outside of the first lead screw 512. The first telescopic electric cylinder 514 is arranged below the first threaded sleeve 513, and the cylinder end of the first telescopic electric cylinder 514 is installed at the bottom of the first threaded sleeve 513. The surface of the first lead screw 512 is provided with a first external thread 515, and the interior of the first threaded sleeve 513 is provided with an internal thread that can cooperate with the first external thread 515; the second The adjusting assembly 52 includes a second motor 521, a second lead screw 522, a second threaded sleeve 523, and a second telescopic electric cylinder 524. One end of the second lead screw 522 is movably connected to the mounting frame 22, and the other end of the second lead screw 522 is transversely mounted on the mounting frame 22 and connected to the second motor 522 arranged on the outside of the mounting frame 22. The second threaded sleeve 523 is movably sleeved on the outside of the second lead screw 522. The second telescopic electric cylinder 524 is arranged below the second threaded sleeve 523, and the cylinder end of the second telescopic electric cylinder 524 is installed at the bottom of the second threaded sleeve 523. The surface of the second lead screw 522 is provided with a second external thread 525, and the inside of the second threaded sleeve 523 is provided with an internal thread that can cooperate with the second external thread 525. The spiral direction of the first external thread 515 is opposite to that of the second external thread 525.

[0028] The operating principle of the first adjusting component 51 and the second adjusting component 52 is a lead screw-nut transmission mechanism. Combining the drive of the motor and the fine-tuning function of the electric cylinder, it realizes the precise adjustment of the position of the cutting component 3 on the surface of the aluminum foil bag coil. The first motor 511 drives the first lead screw 512 to rotate. Since the surface of the first lead screw 512 is provided with a first external thread 515, and the first external thread 515 is a right-handed thread, which mates with the internal thread inside the first thread sleeve 513, the first thread sleeve 513 moves along the axial direction of the first lead screw 512. The second motor 521 drives the second lead screw 522 to rotate. The surface of the second lead screw 522 is provided with a second external thread 525, and the second external thread 525 is a left-handed thread, which mates with the internal thread inside the second thread sleeve 523, causing the second thread sleeve 523 to move along the axial direction of the second lead screw 522.

[0029] The spiral directions of the first external thread 515 and the second external thread 525 are opposite. When the first motor 511 and the second motor 521 rotate in the same direction, the first thread sleeve 513 and the second thread sleeve 523 will move in opposite directions. Conversely, when the first motor 511 and the second motor 521 rotate in opposite directions, the first thread sleeve 513 and the second thread sleeve 523 will move in the same direction, thus increasing the convenience of adjusting the cutting position of the cutting component 3.

[0030] By controlling the rotation direction and speed of the first motor 511 and the second motor 521, the relative position between the cutting components 3 installed on the first adjusting component 51 and the second adjusting component 52 can be adjusted, and the width between them can be adjusted. In the initial state, the initial positions of the two cutting components 3 are adjusted through the first adjusting component 51 and the second adjusting component 52 respectively. The initial position of the cutting component 3 connected to the first adjusting component 51 is at the end of the first lead screw 512 close to the first motor 511, that is, the right end of the first lead screw 512. The initial position of the cutting component 3 connected to the second adjusting component 52 is at the end of the second lead screw 522 far from the second motor 521, that is, the left end of the second lead screw 522.

[0031] Then, start the first motor 511 to drive the first adjustment component 51 to move the connected cutting component 3 to the left end of the first lead screw 512. When the distance between the cutting edge of the cutting circular knife 32 of the cutting component 3 and the right side edge of the aluminum foil bag coil is equal to the width of the right section of the aluminum foil bag coil, the first motor 511 stops running. Then, the first telescopic electric cylinder 514 drives the cutting component 3 to descend, making the cutting edge of its cutting circular knife 32 closely adhere to the surface of the aluminum foil bag coil so that the cutting circular knife 32 can perform cutting. After that, start the second motor 521 to drive the second adjustment component 52 to move the connected cutting component 3 to the right end of the second lead screw 522. When the distance between the cutting edge of the cutting circular knife 32 of the cutting component 3 and the left side edge of the aluminum foil bag coil is equal to the width of the left section of the aluminum foil bag coil, the second motor 521 stops running. Then, the second telescopic electric cylinder 524 drives the cutting component 3 to descend, making the cutting edge of its cutting circular knife 32 closely adhere to the surface of the aluminum foil bag coil. Thus, the cutting circular knives 32 of the two cutting components 3 cut the aluminum foil bag coil into three sections, namely the left section, the middle section, and the right section. The widths between the left section, the middle section, and the right section can be the same or different.

[0032] During the process of determining the cutting distances of the left and right sections of the aluminum foil bag coil, the laser locator 6 projects laser lines onto the surface of the aluminum foil bag, clearly showing the cutting path of the cutting circular knife 32. The operator can adjust the cutting width by measuring the width between the laser lines to ensure the accuracy and precision of the cutting.

[0033] As Figure 3 and Figure 4 shown, as a preferred embodiment of the present invention, the cutting component 3 includes a rotating motor 31 and a cutting circular knife 32. The power output shaft of the rotating motor 31 is fixedly connected to the cutting circular knife 32. When the cutting component 3 operates, the power output shaft of the rotating motor 31 rotates and drives the cutting circular knife 32 to rotate together, thereby realizing the cutting of the aluminum foil bag coil. The cutting circular knife 32 installed on the first adjustment component 51 and the cutting circular knife 32 installed on the second adjustment component 52 are arranged oppositely, which is convenient for the operator to measure the widths of the left and right sections of the aluminum foil bag coil respectively.

[0034] As Figure 3 and Figure 4 shown, as a preferred embodiment of the present invention, the pressing component 4 includes a mounting plate 41, a pressing member 42, and a connecting column 43. The pressing member 42 is vertically arranged and is respectively installed at both ends of the lower surface of the mounting plate 41. The connecting column 43 is arranged below the mounting plate 41. One end of the connecting column 43 is connected to the lower surface of the mounting plate 41, and the other end of the connecting column 43 is connected to the rotating motor 31.

[0035] The pressing component 42 includes a connecting rod 421, a U-shaped connecting frame 422, a pressing wheel 423, and a wheel shaft 424. The pressing wheel 423 is movably connected to the wheel shaft 424. The wheel shaft 424 radially penetrates the pressing wheel 423 at the central position of the pressing wheel 423. Both ends of the wheel shaft 424 are fixedly connected to the U-shaped connecting frame 422. The end portions of both ends of the wheel shaft 424 respectively penetrate through the lower ends of the U-shaped connecting frame 422. The connecting rod 421 is arranged above the U-shaped connecting frame 422. The top of the U-shaped connecting frame 422 is fixedly connected to the lower end of the connecting rod 421. The upper end of the connecting rod 421 is connected to the lower surface of one end of the mounting plate 41.

[0036] The pressing component 42 is connected to the mounting plate 41 through the connecting rod 421. The mounting plate 41 is connected to the rotating motor 31 through the connecting column 43, so that the pressing assembly 4 can move together with the cutting assembly 3. When the cutting assembly 3 is positioned above the aluminum foil bag coil and ready to cut, the pressing wheel 423 in the pressing component 42 will descend until it contacts the surface of the aluminum foil bag coil. The pressing wheel 423 is fixedly connected to the U-shaped connecting frame 422 through the wheel shaft 424, and the U-shaped connecting frame 422 is connected to the mounting plate 41 through the connecting rod 421, enabling the pressing wheel 423 to firmly press the aluminum foil bag coil, which can not only provide sufficient pressure to make the aluminum foil bag coil closely adhere to the cutting table 11, but also will not damage the aluminum foil bag.

[0037] When the pressing assembly 4 presses the aluminum foil bag coil onto the cutting table 11, the cutting assembly 3 starts to work. The rotating motor 31 is started, and the power output shaft of the rotating motor 31 drives the cutting circular knife 32 to rotate. The blade of the cutting circular knife 32 contacts the aluminum foil bag coil, and the cutting process begins. The laser line projected by the laser locator 6 is on the surface of the aluminum foil bag, providing an intuitive indication of the cutting path for the operator and helping to ensure the accuracy of the cutting width.

[0038] The pressing assembly 4 is connected to the cutting assembly 3 through the connecting column 43, ensuring that the two can move synchronously during the cutting process and maintaining the relative position stability between the cutting circular knife 32 and the pressing wheel 423. Before the cutting starts, the pressing assembly 4 first presses the aluminum foil bag coil, and then the cutting assembly 3 starts to rotate the cutting circular knife 32 for cutting, thus avoiding the offset of the aluminum foil bag coil during the cutting process and improving the cutting accuracy. By adjusting the first adjustment component 51 and the second adjustment component 52, the distance between the two cutting circular knives 32 can be flexibly changed, so as to meet the cutting requirements for different widths of the aluminum foil bag coil. At the same time, the assistance of the laser locator 6 makes the width adjustment more accurate.

[0039] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
