Description

Technical Field

[0001] This application relates to the field of cutting machine technology, specifically to a turntable mechanism and a cutting machine. Background Technology

[0002] The turntable mechanism of related cutting machines is usually equipped with multiple cutters, which are evenly distributed around the circumference of the turntable. This ensures a uniform mass distribution of the turntable mechanism and avoids vibration caused by uneven mass distribution. However, the large number of cutters results in a shorter cutting length for the material to be cut. To increase the cutting length, the rotation speed of the turntable mechanism or the production speed of the material to be cut must be reduced. Reducing the production speed of the material to be cut will lead to a decrease in production capacity. Reducing the rotation speed of the turntable mechanism will result in the material to be cut not being cut, resulting in "tailed filaments" or "double-length filaments".

[0003] Therefore, how to solve the problem of short cutting length of materials under the premise of ensuring material production quality and efficiency has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this application is to provide a turntable mechanism for a cutting machine and a cutting machine in general, which solves the problem of short cutting length of the material to be cut while ensuring material production quality and efficiency. The specific solution is as follows:

[0005] A turntable mechanism for a cutting machine includes a turntable part, a cutting part, and a counterweight part. The turntable part is rotatable about a rotation axis. The cutting part and the counterweight part have equal masses. The cutting part and the counterweight part are detachably connected to the turntable part and are evenly arranged along the circumference of the turntable part.

[0006] Optionally, the turntable includes a turntable body and at least two connecting shafts. The connecting shafts are mounted on the turntable body, extend radially along the turntable body, and are evenly distributed circumferentially along the turntable body. The outer ends of the connecting shafts extend to the outside of the turntable body. The cutter and the counterweight are detachably connected to the corresponding connecting shafts.

[0007] Optionally, the included angle between two adjacent connecting shafts is 60°, the number of the cutter part and the number of the counterweight part are both one, and the included angle between the counterweight part and the cutter part is 180°.

[0008] Optionally, the included angle between two adjacent connecting shafts is 60°, the number of the cutting blade is one, the number of the counterweight is two, the included angle between the two counterweights is 120°, and the included angle between the cutting blade and the counterweight is 120°.

[0009] Optionally, the included angle between two adjacent connecting shafts is 60°, the number of cutting parts is one, the number of counterweight parts is five, the included angle between two adjacent counterweight parts is 60°, and the included angle between the cutting part and the adjacent counterweight part is 60°.

[0010] Optionally, the connecting shaft includes a first diameter section, the counterweight is fitted onto the first diameter section, and connected by a spline;

[0011] The connecting shaft has a first limiting part, and the cutting machine further includes a fixing member, which is detachably connected to the connecting shaft. The counterweight is axially limited and installed between the first limiting part and the fixing member.

[0012] Optionally, the connecting shaft further includes a second diameter segment, the first diameter segment is connected to the outer end of the second diameter segment, the diameter of the first diameter segment is smaller than the diameter of the second diameter segment, and a stepped wall is formed between the first diameter segment and the second diameter segment, the stepped wall being the first limiting part.

[0013] Optionally, the connecting shaft further includes a third diameter section connecting the first diameter section, the third diameter section being close to the outer end of the connecting shaft, the diameter of the third diameter section being smaller than the diameter of the first diameter section, the outer wall of the third diameter section being provided with external threads, and the length L of the first diameter section being greater than the thickness T of the counterweight.

[0014] The fastener includes a fixing nut and a washer. The washer is fitted onto the first diameter section and abuts against the outer wall of the counterweight. The fixing nut is fitted onto the third diameter section and threadedly connected. The fixing nut abuts against the outer wall of the washer.

[0015] This application also provides a cutting machine, including the aforementioned cutting machine's turntable mechanism.

[0016] Optionally, the cutting machine further includes a machine body, the turntable is rotatably connected to the lower side of the machine body, the machine body is provided with a through hole for the material to be cut to pass through, and the projection of the counterweight toward the machine body and the lower port of the through hole are offset from each other.

[0017] The technical effects of this application are as follows:

[0018] This application adds a counterweight to the cutting machine. The mass of the cutting part and the counterweight are equal. Both the cutting part and the counterweight are detachably connected to the turntable and are evenly distributed along the circumference of the turntable, so that the mass of the entire turntable mechanism is evenly distributed, avoiding vibration of the cutting machine caused by uneven mass distribution. The detachable connection method allows the number of cutting parts to be adjusted according to production needs. When there is only one cutting part, the cutting part only cuts the material to be cut once for every 360° rotation of the turntable, increasing the cutting length of the material to be cut and meeting the needs of producing long materials. There is no need to reduce the rotation speed of the turntable or the production speed of the material to be cut. While ensuring the production rate of the material to be cut, it avoids the phenomenon of uncut material and "tailed filaments" or "double-length filaments". Thus, the problem of short cutting length of the material to be cut is solved while ensuring the production quality and efficiency of the material. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] It should be understood that the phrase "some embodiments" throughout the specification means that a specific feature, structure, or characteristic related to an embodiment is included in at least one embodiment of this application. Therefore, "some embodiments" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0029] In this description, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art will understand the specific meaning of these terms in this document based on the specific circumstances.

[0030] In this article, along the radial direction of the turntable body 11, the direction closer to the interior of the turntable body 11 is called "inner", and the direction closer to the exterior of the turntable body 11 is called "outer".

[0031] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a specific embodiment of the cutting machine provided in this application.

[0032] This application provides a turntable mechanism for a cutting machine, including a turntable part 1, a cutting part 2, and a counterweight part 3. The turntable part 1 can rotate around a rotation axis L. The cutting part 2 and the counterweight part 3 have equal masses. The cutting part 2 and the counterweight part 3 are detachably connected to the turntable part 1 and are evenly arranged along the circumference of the turntable part 1.

[0033] Related cutting machines typically employ multiple cutters evenly distributed around the circumference of the turntable. This ensures uniform mass distribution across the rotating structure, preventing vibration caused by uneven mass distribution. However, a large number of cutters results in shorter cutting lengths for the material. If the machine has two cutters at a 180° angle, the cutter cuts the material once for every 180° rotation of the turntable. With three cutters at a 120° angle, the cutter cuts the material once for every 120° rotation of the turntable. With six cutters at a 60° angle, the cutter cuts the material once for every 60° rotation of the turntable. In practice, it has been found that, with constant turntable speed and material production speed, the cutting machine can only produce materials with a maximum cutting length of 51mm.

[0034] In this embodiment, the turntable mechanism of the cutting machine is equipped with a counterweight 3. The weights of the cutting blade 2 and the counterweight 3 are equal. Both the cutting blade 2 and the counterweight 3 are detachably connected to the turntable 1 and are evenly distributed along the circumference of the turntable 1, so that the weight of the entire turntable mechanism is evenly distributed, avoiding vibration of the cutting machine caused by uneven weight distribution. The detachable connection method allows the number of cutting blades 2 to be flexibly adjusted according to production needs. For example, if there is only one cutting blade 2, the cutting blade 2 will cut the material to be cut once for every 360° rotation of the turntable 1, increasing the cutting length of the material to be cut and meeting the needs of long-specification material production. With the rotation speed of the turntable 1 and the production speed of the material to be cut remaining unchanged, the cutting machine can complete the production of materials with a maximum cutting length of 90mm. There is no need to reduce the rotation speed of the turntable 1 or the production speed of the material to be cut. While ensuring the production rate of the material to be cut, it avoids the phenomenon of the material to be cut not being able to be cut, resulting in "tailed filaments" or "double-length filaments". Thus, the problem of short cutting length of the material to be cut is solved while ensuring the production quality and efficiency of the material.

[0035] In this embodiment, the cutter part 2 includes a cutter holder 21 and a cutter (not shown in the figure). The cutter holder 21 is connected to the turntable part 1, and the cutter is connected to the cutter holder 21. The sum of the masses of the cutter holder 21 and the cutter is equal to the mass of each counterweight part 3.

[0036] As set above, this embodiment of the application takes into account the mass of both the knife holder 21 and the cutter, making the mass of the cutter part 2 more accurate. The sum of the mass of the knife holder 21 and the cutter is set to be equal to the mass of each counterweight part 3, making the mass distribution of the entire rotating structure more uniform, reducing the eccentric vibration of the turntable part 1, and improving the smoothness of the rotation of the turntable part 1.

[0037] Please continue to refer to this. Figure 1In this embodiment of the application, the turntable part 1 includes a turntable body 11 and at least two connecting shafts 12. The connecting shafts 12 are mounted on the turntable body 11, extend radially along the turntable body 11, and are evenly distributed circumferentially along the turntable body 11. The outer ends of the connecting shafts 12 extend to the outside of the turntable body 11. The cutter part 2 and the counterweight part 3 are detachably connected to the corresponding connecting shafts 12.

[0038] As set above, in the cutting machine of this application embodiment, the cutting blade 2 and the counterweight 3 are connected to the turntable 1 through the same connecting structure (connecting shaft 12). The connecting shaft 12 is evenly distributed along the circumference of the turntable body 11, so that the mass distribution of the turntable 1 is uniform, minimizing the vibration of the turntable 1 during rotation, improving the operational stability of the turntable 1, and extending its service life.

[0039] In some embodiments of this application, the number of connecting shafts 12 is six, the included angle between two adjacent connecting shafts 12 is 60°, the number of cutting parts 2 is one, and the number of counterweight parts 3 can be one, two, or five. Specifically:

[0040] The number of counterweights 3 is one, and the included angle between the counterweights 3 and the cutter 2 is 180°, that is, the counterweights 3 and the cutter 2 are arranged opposite each other along the radial direction of the turntable 1;

[0041] There are two counterweights 3, and the included angle between the two counterweights 3 is 120°. The included angle between the cutter part 2 and the counterweights 3 is also 120°.

[0042] There are five counterweights 3, and the included angle between two adjacent counterweights 3 is 60°. The included angle between the cutter part 2 and the adjacent counterweight 3 is also 60°.

[0043] All three implementation methods described above can achieve a uniform distribution of the counterweight 3 and the cutting blade 2 along the circumference of the turntable 1, resulting in a uniform mass distribution throughout the rotating structure and improving the operational stability of the turntable 1. Among these, when the counterweight 3 is singular, the number of parts in the cutting machine is minimized, which helps simplify the machine's structure and reduce costs.

[0044] Please continue to refer to this. Figure 1 In this embodiment of the application, the connecting shaft 12 includes a first diameter section 121, the counterweight 3 is fitted with the first diameter section 121 and connected by a spline;

[0045] The connecting shaft 12 has a first limiting part, and the cutting machine also includes a fixing member, which is detachably connected to the connecting shaft 12. The counterweight 3 is axially limited and installed between the first limiting part and the fixing member.

[0046] As set above, in this embodiment of the application, the counterweight 3 is fitted with the first diameter section 121 and connected by a spline, so that the counterweight 3 is reliably limited in the circumferential direction. The counterweight 3 is installed between the first limiting part and the fixing part in the axial direction, so that the counterweight 3 is reliably limited in the axial direction. This ensures that the counterweight 3 is reliably connected to the connecting shaft 12, and avoids the counterweight 3 from shifting its position or even detaching from the connecting shaft 12 during the rotation of the turntable 1, thus ensuring the safe and stable operation of the cutting machine.

[0047] Please continue to refer to this. Figure 1 In this embodiment of the application, the connecting shaft 12 further includes a second diameter segment 122, and a first diameter segment 121 is connected to the outer end of the second diameter segment 122. The diameter of the first diameter segment 121 is smaller than the diameter of the second diameter segment 122. A stepped wall is formed between the first diameter segment 121 and the second diameter segment 122, and the stepped wall is a first limiting part.

[0048] As set above, this embodiment of the application uses the variable diameter design of the connecting shaft 12 to form a stepped wall between the first diameter section 121 and the second diameter section 122. The stepped wall axially limits the counterweight 3, ensuring reliable axial limiting of the counterweight 3. It also simplifies the limiting structure of the counterweight 3, making the structure simple, easy to process, and reducing processing costs.

[0049] Please continue to refer to this. Figure 1 In this embodiment of the application, the connecting shaft 12 further includes a third diameter section 123 that connects to the first diameter section 121. The third diameter section 123 is close to the outer end of the connecting shaft 12. The diameter of the third diameter section 123 is smaller than the diameter of the first diameter section 121. The outer wall of the third diameter section 123 is provided with an external thread. The length L of the first diameter section 121 is greater than the thickness T of the counterweight 3.

[0050] The fastener includes a fixing nut 51 and a washer 52. The washer 52 is fitted onto the first diameter section 121 and abuts against the outer wall of the counterweight part 3. The fixing nut 51 is fitted onto the third diameter section 123 and threadedly connected. The fixing nut 51 abuts against the outer wall of the washer 52.

[0051] As described above, in this embodiment, the fixing nut 51 is fitted onto the third diameter section 123 and threadedly connected. By rotating the fixing nut 51, the relative position between the fixing nut 51 and the washer 52 can be precisely controlled. When the fixing nut 51 is tightened, the counterweight 3 is pressed between the stepped wall of the connecting shaft 12 and the washer 52, ensuring reliable axial positioning of the counterweight 3.

[0052] In this embodiment, the cutter part 2 and the counterweight part 3 are fixed in the same way. The cutter holder 21 is circumferentially limited by a spline and a connecting shaft 12, and axially limited by a fixing nut and a stepped wall. A washer is provided between the cutter holder 21 and the fixing nut. By fixing the cutter part 2 and the counterweight part 3 with the same fixing structure, the difference in mass caused by different fixing structures is avoided, and the mass balance of the entire rotating structure is further guaranteed.

[0053] This application also provides a cutting machine, including the aforementioned turntable mechanism of the cutting machine.

[0054] Please continue to refer to this. Figure 1 In this embodiment of the application, the cutting machine also includes a machine body 4, a turntable 1 is rotatably connected to the lower side of the machine body 4, the machine body 4 is provided with a through hole 4a for the material to be cut to pass through, and the projection of the counterweight 3 toward the machine body 4 and the lower port of the through hole 4a are offset from each other.

[0055] As described above, in this embodiment of the application, the counterweight 3 is designed such that its projection toward the machine body 4 is offset from the lower port of the through hole 4a, thereby preventing the counterweight 3 from encroaching on the falling path of the material to be cut, ensuring that the material to be cut can pass smoothly through the through hole 4a, and ensuring that the cutter 2 can smoothly complete the cutting of the material to be cut, thus improving the cutting efficiency of the cutting machine.

[0056] Depend on Figure 1 It can be seen that although the connecting shaft 12 used to connect the counterweight 3 is located directly below the through hole 4a, the distance between the connecting shaft 12 and the lower end of the through hole 4a is relatively large. When the counterweight 3 rotates to... Figure 1 When the position shown is such that the material to be cut is located above the connecting shaft 12, the material to be cut will not contact the connecting shaft 12, therefore the connecting shaft 12 will not interfere with the falling of the material to be cut.

[0057] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
