Description

A tracking and cutting device CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is based on and claims priority to a Chinese patent application with an application date of "December 29, 2023", application number "2023236477817", and invention name "A tracking and cutting device". The full text of the Chinese patent application is hereby cited in this application as a part of this application. Technical Field

[0002] The present invention relates to the technical field of slitting equipment, and in particular to a tracking slitting device. Background Art

[0003] Slitting equipment is an indispensable auxiliary equipment for BFS (Blow-Fill-Seal) unreinforced continuous sheet materials.

[0004] Chinese Patent Publication No. CN 212312224 U discloses a die-cutting structure for waste bottles, comprising a first die and a second die positioned opposite each other. By positioning an ejector pin between a second connecting plate and a pre-pressing plate, when the die-cutting die driving device drives the second die-cutting plate to trim, the ejector pin passes through the pre-pressing plate to secure the waste bottle. When the die-cutting die driving device resets the second die-cutting plate, the ejector pin resets through the pre-pressing plate, and the waste bottle pinned to the ejector pin is squeezed out of the pre-pressing plate. The cutting, securing, and dropping of the waste bottle are driven by a single driving device, resulting in low cost, simple structure, and easy assembly. The applicant discovered that this technical solution effectively provides a static, fixed sheet material slitting mechanism. The positions of the first and second dies, which perform the cutting function, do not move with the conveyor line for the bottle sheets to be cut. This die-cutting mechanism operates reliably when the cutting speed requirement is low (a cycle of more than three seconds), but is unsuitable for situations where the cutting speed requirement is less than three seconds. In order to meet the slitting requirements of high-speed BFS products, a matching high-speed slitting equipment is urgently needed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a tracking slitting device with a high slitting speed.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A tracking slitting device includes a slitting mechanism and a bottle row input mechanism. The bottle row input mechanism inputs materials into the slitting mechanism for slitting. It also includes a linear drive mechanism. The slitting mechanism is located on the linear drive mechanism and can reciprocate along the bottle row output direction under the drive of the linear drive mechanism.

[0008] In some embodiments of the present invention, the slitting mechanism includes a slitting unit, a clamping unit and a tensioning unit. Multiple slitting units are relatively arranged on both sides of the bottle row input mechanism. The clamping unit is connected to the slitting unit and is used to drive the relatively arranged slitting units to close or open. The two ends of the slitting unit are respectively connected to the tensioning unit, and the tensioning unit is used to tighten the material when the relatively arranged slitting units are closed.

[0009] The clamping unit further includes a first mounting seat and an opening and closing driving member, wherein the first mounting seat is connected to the linear driving mechanism, and the opening and closing driving member is used to drive the relatively arranged slitting unit to close or open.

[0010] The slitting mechanism further includes a first positioning member, which is connected to the first mounting seat and is used to position the material.

[0011] The cutting unit includes a cutting block and a first support base. A plurality of cutting blocks are arranged at intervals along the bottle row output direction and connected to the first support base. The opening and closing driving member is connected to the first support base.

[0012] The linear drive mechanism includes a slide rail, and the slitting mechanism is slidably connected to the slide rail.

[0013] The tracking and cutting device further comprises a side guard mechanism, which is arranged on both sides of the bottle row input mechanism and is used to prevent materials from dumping.

[0014] The edge retaining mechanism includes a second mounting seat and a first stop block and a second stop block located on the second mounting seat. The two second mounting seats are respectively arranged on both sides of the slitting mechanism. The first stop block and the second stop block are respectively connected between the two second mounting seats. The height of the first stop block is lower than that of the second stop block.

[0015] The slitting mechanism further includes a second positioning member, which is connected to the second stopper and is used to position the material.

[0016] The tracking and cutting device further comprises a frame, and the cutting mechanism, the bottle row input mechanism and the linear drive mechanism are mounted on the frame.

For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements.

[0028] As shown in Figures 1 to 3, the tracking slitting device of the present invention includes a slitting mechanism 3 and a bottle row input mechanism 5. The bottle row input mechanism 5 inputs material into the slitting mechanism 3 for slitting. The device also includes a linear drive mechanism 2. The slitting mechanism 3 is located on the linear drive mechanism 2 and is driven by the linear drive mechanism 2 to reciprocate along the bottle row output direction. The linear drive mechanism 2 of the present invention drives the slitting mechanism 3 to reciprocate along the bottle row output direction, allowing the slitting mechanism 3 to track the material (in this embodiment, unreinforced continuous support sheet material) as it is transported and slit during slitting. This improves the slitting speed compared to static slitting of fixed sheet material, reducing the slitting speed to less than 3 seconds, meeting the slitting requirements of high-speed BFS products and achieving high-speed slitting.

[0029] The slitting mechanism 3 includes a slitting unit 32, a clamping unit 31, and a tensioning unit 33. Multiple slitting units 32 are positioned opposite each other on either side of the bottle row input mechanism 5. The clamping unit 31 is connected to the slitting unit 32 and is used to drive the opposing slitting units 32 to close or open. Tensioning units 33 are connected to each end of the slitting unit 32 to tension the material when the opposing slitting units 32 are closed. During slitting, the material moves along the bottle row input mechanism 5, and the linear drive mechanism 2 drives the slitting mechanism 3 to track the material's movement. The clamping unit 31 drives the slitting unit 32 to first clamp the sheet material to be cut. During this movement, the tensioning unit 33 tensions the sheet material. After the slitting unit 32 completes slitting, the linear drive mechanism 2 drives the slitting mechanism 3 to quickly return to its original position and begin the next slitting cycle.

[0030] The clamping unit 31 further includes a first mounting seat 311 and an opening and closing driving member 312 . The first mounting seat 311 is connected to the linear driving mechanism 2 . The opening and closing driving member 312 is used to drive the relatively arranged slitting unit 32 to close or open.

[0031] The slitting mechanism 3 also includes a first positioning member 34, which is connected to the first mounting base 311 and is used to locate the material. When the material on the bottle row input mechanism 5 moves to the position determined by the first positioning member 34, the first positioning member 34 transmits information to the controller, which controls the clamping unit 31 to drive the slitting unit 32 to clamp the material to be cut, thereby starting slitting.

[0032] The slitting unit 32 includes a slitting block 321 and a first support base 322. Multiple slitting blocks 321 are spaced apart along the bottle delivery direction and connected to the first support base 322. The opening and closing drive 312 is connected to the first support base 322. Multiple slitting blocks 321 connected via the first support base 322 can be slid by a single opening and closing drive 312, providing convenient operation and cost savings.

[0033] In this embodiment, the linear drive mechanism 2 includes a slide rail 21, and the slitting mechanism 3 is slidably connected to the slide rail 21. The slide rail 21 is arranged along the bottle output direction. In other embodiments, the linear drive mechanism 2 includes a slide bar or a chain, etc., which can also achieve the same technical effect.

[0034] In this embodiment, the first support base 322 is slidably disposed on the slide rail 21 .

[0035] The tracking and slitting device also includes a side guard mechanism 4, which is arranged on both sides of the bottle row input mechanism 5 and is used to prevent the material from dumping. It is generally difficult for the sheet material to stand on the bottle row input mechanism 5 by itself, so the side guard mechanism 4 is used to limit the sheet material.

[0036] The edge retaining mechanism 4 includes a second mounting base 41 and a first stopper 42 and a second stopper 43 located on the second mounting base 41. The two second mounting bases 41 are respectively arranged on both sides of the slitting mechanism 3. The first stopper 42 and the second stopper 43 are respectively connected between the two second mounting bases 41. The height of the first stopper 42 is lower than that of the second stopper 43. The use of the first stopper 42 and the second stopper 43 of different heights to provide a double anti-dumping restriction for the sheet material is more stable and reliable than the anti-dumping arrangement with only one stopper.

[0037] In this embodiment, each second mounting seat 41 includes two vertically arranged main mounting seats 411 and a secondary mounting seat 412, the secondary mounting seat 412 is detachably connected to the main mounting seat 411, the first stop block 42 is installed between the main mounting seats 411 of the two second mounting seats 41, and the second stop block 43 is installed between the secondary mounting seats 412 of the two second mounting seats 41.

[0038] In this embodiment, the main mounting seat 411 and the auxiliary mounting seat 412 are respectively provided with support ears, and the support ears of the main mounting seat 411 and the auxiliary mounting seat 412 are connected by bolts or screws. By adjusting the bolts or screws to change the distance between the two support ears, the technical effect of the height of the auxiliary mounting seat 412 relative to the main mounting seat 411 is achieved to meet the needs of anti-dumping of sheet materials of different heights.

[0039] In this embodiment, the lugs of the auxiliary mounting seat 412 are located at the lower part of the auxiliary mounting seat 412 , and the lugs of the main mounting seat 411 are located at the upper part of the main mounting seat 411 . The lugs of the main mounting seat 411 and the auxiliary mounting seat 412 are arranged facing each other.

[0040] The slitting mechanism 3 also includes a second positioning member 35, which is connected to the second stopper 43 and is used to determine the position of the material. The second positioning member 35 is located above and between the two second stoppers 43 and is used to determine whether the material is in the middle of the bottle row input mechanism 5, thereby facilitating better clamping and slitting.

[0041] The tracking and cutting device further comprises a frame 1 , on which a cutting mechanism 3 , a bottle row input mechanism 5 , and a linear drive mechanism 2 are mounted.

[0042] In this embodiment, the second mounting seat 41 is mounted on the rack 1 . Preferably, the main mounting seat 411 is mounted on the rack 1 , and the auxiliary mounting seat 412 is mounted on the main mounting seat 411 and spaced apart from the rack 1 .

[0043] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes.
