Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and particularly relates to a cutting device. Background Art

[0002] Nowadays, automated cutting has become a common technical means in the field of product production. By using automated cutting equipment, the accuracy of cutting dimensions and the cutting efficiency can be improved, and production safety accidents caused by manual cutting can be avoided. Existing automated cutting technologies are often set as a link in the production line of products. The products to be cut are in a continuous flowing state on the production line. Especially for flexible materials such as fabrics and papers, they need to move continuously on the production line. Therefore, in order to enable the products to keep moving without stopping during the flow process and improve production efficiency, the cutting equipment is required to have a non-stop cutting interval, which is also beneficial to improving the service life of the cutting equipment. Summary of the Invention

[0003] To solve the problems of the existing technology, an embodiment of the present invention provides a cutting device. The technical solution is as follows:

[0004] A cutting device is provided, including a cutter mechanism, and the cutter mechanism includes:

[0005] A transmission assembly, including: a rotating shaft eccentrically driven by a motor;

[0006] A cutting assembly, including: a cutter and a guide rod. The cutter is connected to the rotating shaft and the guide rod. The rotating shaft and the guide rod are vertically arranged. The rotating shaft rotates eccentrically relative to the output shaft of the motor under the drive of the motor, and then drives the cutter to perform a reciprocating motion along the guide rod.

[0007] Further, one end of the rotating shaft connected to the output shaft of the motor is provided with a connecting portion, and the connecting portion is eccentrically connected to a connecting member, and the connecting member is driven by the motor.

[0008] Further, the connecting portion includes a first cutting surface structure axially arranged on the end surface of the rotating shaft, and the connecting member includes a second cutting surface structure axially arranged on the end surface of the connecting member. The maximum thickness of the first cutting surface structure is inconsistent with the maximum thickness of the second cutting surface structure, so as to realize the eccentric connection between the connecting portion and the connecting member.

[0009] Further, the first cutting surface structure and the second cutting surface structure are relatively fitted and installed and fixed by bolts.

[0010] Further, the cutting knife is arranged on the floating seat through a fixed seat. The floating seat is sleeved on the rotating shaft and the guiding rod. The eccentric rotation of the rotating shaft relative to the output shaft of the motor drives the floating seat to move along the guiding rod, so that the cutting knife performs cutting.

[0011] Further, the side surface of the cut block is a cutting edge surface.

[0012] Further, the device includes two cutting knife mechanisms arranged up and down. The cutting target is arranged between the two cutting knife mechanisms. When the cutting knives included in the two cutting knife mechanisms move relative to each other, the cutting edge surfaces of the two cutting knives are attached to each other, so as to cut off the cutting target.

[0013] Further, one end of the guiding rod of the cutting knife mechanism arranged below is fixed on the floating seat of the cutting knife mechanism arranged above, and one end of the guiding rod of the cutting knife mechanism arranged above is fixed on the floating seat of the cutting knife mechanism arranged below.

[0014] Further, a cutting edge rib is provided on the bottom surface of the cutting knife.

[0015] Further, the device further includes a receiving plate. The receiving plate is arranged below the cutting knife mechanism. The cutting target is arranged between the cutting knife mechanism and the receiving plate. The guiding rod is fixed on the receiving plate. The cutting knife moves downward along the guiding rod and contacts the receiving plate, so as to cut off the cutting mechanism.

[0016] The beneficial effects brought by the technical solution provided by the embodiment of the present invention are as follows:

[0017] 1. In the present invention, the rotational motion of the output shaft of the motor is converted into the linear motion of the floating block along the guiding shaft through the eccentric transmission of the rotating shaft and the motor, so that the cutting mechanism has a non-stop cutting interval, which is beneficial to improving the cutting efficiency and the service life of the cutting device;

[0018] 2. The present invention includes two cutting knife mechanisms arranged up and down, and realizes the cutting function of the cutting target moving therebetween through the opposite movement of the two, without affecting the movement of the cutting target on the production line, which is beneficial to improving the production efficiency.

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0026] It should be noted that the descriptions of the present invention regarding directions such as "left", "right", and "lower" are all defined based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device must be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention. The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. In the description of the present invention, the meaning of "multiple" or "several" is more than two, unless otherwise clearly and specifically defined.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, mechanical terms such as "installation" and "setting" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] In existing automated cutting devices, since the cutting tool needs to move up and down reciprocally, the transmission component that drives the reciprocating movement of the cutting tool also needs to rotate reciprocally. This will cause the cutting device to have a paused cutting interval, thereby reducing the service life of the cutting device.

[0029] To solve the above technical problems, the present invention discloses a cutting device, and the specific technical solution is as follows:

[0030] As shown in Figure 1 and Figure 2 , a cutting device includes at least one cutting tool mechanism. The cutting tool mechanism includes a transmission component 1.1 and a cutting component 1.2, wherein the transmission component 1.1 is used to drive the cutting component 1.2 to achieve the cutting function.

[0031] The transmission component 1.1 includes a rotating shaft 1.1.1, and the rotating shaft 1.1.1 is eccentrically driven by a motor (not shown).

[0032] The cutting component 1.2 includes a cutting tool 1.2.1 and a guide rod 1.2.2. The cutting tool 1.2.1 is connected to the rotating shaft 1.1.1 and the guide rod 1.2.2. The rotating shaft 1.1.1 is perpendicularly arranged with the guide rod 1.2.2. The rotating shaft 1.1.1 performs eccentric drive relative to the motor under the drive of the motor, and then drives the cutting tool 1.2.1 to perform reciprocating movement along the guide rod 1.2.2.

[0033] As described above, the rotating shaft 1.1.1 can be directly eccentrically connected to the output shaft of the motor, or achieve eccentric drive with the motor through the transmission of the connecting piece 1.1.3. The cutting tool 1.2.1 can be directly or indirectly sleeved on the rotating shaft 1.1.1, and at the same time can be directly or indirectly sleeved on the guide rod 1.2.2. Since the rotating shaft 1.1.1 rotates eccentrically and the rotating shaft 1.1.1 is perpendicularly arranged with the guide rod 1.2.2, the rotational movement of the rotating shaft 1.1.1 can be converted into a linear movement along the guide rod 1.2.2. The eccentric rotation of the rotating shaft enables the motor to achieve the linear reciprocating movement of the cutting tool without having to rotate back and forth, thereby enabling the cutting device to have a non-paused cutting interval.

[0034] Figure 3 For Figure 2 the detailed structure schematic diagram at position A in Figure 4 , as shown in

[0035] As described above, a technical solution is provided in which the rotating shaft is indirectly connected to the motor, and the connecting portion 1.1.2 of the rotating shaft 1.1.1 is eccentrically connected to the connecting member 1.1.3. There are two specific forms of the transmission between the connecting member 1.1.3 and the motor: the first is that the motor directly drives the connecting member 1.1.3 to rotate, and the second is that the motor drives the connecting member 1.1.3 to rotate through a gear or a belt.

[0036] Furthermore, as Figure 3 shown, as an embodiment, the connecting portion 1.1.2 includes a first cut surface structure axially provided on the end surface of the rotating shaft 1.1.1. The connecting member 1.1.3 is driven to rotate by the motor and includes a second cut surface structure axially provided on the end surface of the connecting member 1.1.3. The maximum thickness of the first cut surface structure is inconsistent with the maximum thickness of the second cut surface structure.

[0037] As described above, the first cut surface structure is the vertical surface structure in the stepped structure composed of a vertical surface and a flat surface at the end of the rotating shaft 1.1.1, and the second cut surface structure is the vertical surface structure in the stepped structure composed of a vertical surface and a flat surface at the end of the connecting member 1.1.3. The different maximum thicknesses of the first cut surface structure and the second cut surface structure can ensure the eccentric connection between the rotating shaft 1.1.1 and the connecting member 1.1.3.

[0038] As an embodiment, the relative fitting and installation of the first cut surface structure and the second cut surface structure are fixed by bolts.

[0039] As described above, the relative installation of the first cut surface structure and the second cut surface structure means that the vertical surfaces of the first cut surface structure and the second cut surface structure are attached.

[0040] As an embodiment, the cutting assembly 3 further includes: a fixed seat 1.2.4 and a floating seat 1.2.3. The above-mentioned cutting knife 1.2.1 is arranged on the fixed seat 1.2.4, and the fixed seat 1.2.4 is arranged on the floating seat 1.2.3. The floating seat 1.2.3 is provided with a sleeve hole penetrating through its bottom surface and top surface, and is sleeved on the guide rod 1.2.2 through this sleeve hole. In addition, the floating seat 1.2.3 is also provided with a sleeve hole penetrating through its front surface and rear surface, and is sleeved on the rotating shaft 1.1.1 through this sleeve hole.

[0041] As described above, the floating seat 1.2.3 can reciprocate along the guide rod 1.2.2, and the fixed seat 1.2.4 mainly serves to install the cutting knife 1.2.1. Further, the cutting knife 1.2.1 can be arranged on the bottom surface or the side surface of the fixed seat 1.2.4.

[0042] As described above, the present invention provides a cutting device including at least one cutter mechanism. The cutting device has a structure in which a rotating shaft is eccentrically connected to a motor. Therefore, the rotating shaft can continuously rotate driven by the output shaft of the motor, and the reciprocating motion of the cutter can be realized. The following provides two structural solutions of the cutting device including the above cutter mechanism:

[0043] As an embodiment, a cutting edge ridge (not shown) is provided on the bottom surface of the cutter, and the cutting edge ridge is used to provide a cutting function. A receiving plate is provided below the cutter mechanism, and the cutting target is arranged between the cutter mechanism and the receiving plate. The guide rod is fixed on the receiving plate, and the cutter moves downward along the guide rod to contact the receiving plate, thereby cutting off the cutting mechanism.

[0044] As described above, the provided cutting device includes only one cutter mechanism. Among them, the receiving plate (not shown) is fixedly arranged, the cutter of the cutter mechanism moves relative to the receiving plate, and the cutting target is placed on the receiving plate. When the cutter moves to contact the receiving plate, the cutting function is realized.

[0045] As Figure 4 shown, as an embodiment, the cutter 1.2.1 is a rectangular block, and the side surface of the block is a cutting edge surface 1.2.1.1, and the cutting edge surface 1.2.1.1 can perform a cutting function. The cutting device includes two cutter mechanisms arranged up and down, and the cutting target is arranged between the two cutters. Among the two cutter mechanisms arranged up and down, the upper cutter mechanism has the same structure as the lower cutter mechanism. However, it is the structure obtained by symmetrically setting the lower cutter mechanism with respect to the horizontal line and then flipping it 180° along the vertical axis, that is, as Figure 4 shown by the arrow direction in, when the cutters included in the two cutter mechanisms move relative to each other, the cutting edge surfaces 1.2.1.1 of the two cutters can be attached, the cutter of the upper cutter mechanism exerts a downward force, and the cutter of the lower cutter mechanism exerts an upward force, thereby cutting off the cutting target 3 between the two cutters.

[0046] As described above, in the disclosed cutting device, the cutters in the upper and lower cutter mechanisms move relatively and alternately, and the cutting target can be cut off. The two cutters support each other for the cutting target, and no additional receiving structure is required, which can ensure the uninterrupted flow of the cutting target on the production line.

[0047] Furthermore, one end of the guide rod 1.2.2 of the cutter mechanism arranged below is fixed on the floating seat 1.2.3 of the cutter mechanism arranged above, and one end of the guide rod 1.2.2 of the cutter mechanism arranged above is fixed on the floating seat 1.2.3 of the cutter mechanism arranged below.

[0048] As described above, the setting method of the guide rod 1.2.2 can simplify the overall structure of the cutting device without additional guide rod fixing components.

[0049] Any combination of the above optional technical solutions can form an optional embodiment of the present invention. The following provides a preferred implementation manner, and various other implementation manners will not be elaborated one by one here.

[0050] As Figure 1 and Figure 2 shown, a cutting device includes: an upper cutter mechanism 1 and a lower cutter mechanism 2, which have the same structure and specifically include: a transmission component 1.1 and a cutting component 1.2. As Figure 3 shown, the transmission component 1.1 includes: a rotating shaft 1.1.1 and a connecting piece 1.1.3. Both ends of the rotating shaft 1.1.1 have connecting parts 1.1.2. There are two connecting pieces 1.1.3, which are respectively connected to the connecting parts 1.1.2 at both ends of the rotating shaft 1.1.1. The connecting part 1.1.2 is a first cut surface structure along the axial direction of the rotating shaft. The connecting piece 1.1.3 has a second cut surface structure along the axial direction of the connecting piece. The thickness of the first cut surface structure is less than the thickness of the second cut surface structure. The two cut surfaces are attached and fixedly installed through bolts 1.1.4, so that the rotating shaft 1.1.1 is eccentrically connected to the connecting piece 1.1.3. The connecting piece is driven by a gear (not shown) and an electric motor. Specifically, the connecting pieces 1.1.3 in the upper cutter mechanism 1 and the lower cutter mechanism 2 are both connected to a gear, and the two are meshed. Taking the rotating shaft 1.1.1 in the lower cutter mechanism 2 as the driving shaft, the electric motor drives the connecting piece 1.1.3 in the lower cutter mechanism 2 to rotate through the gear. The gear in the lower cutter mechanism 2 is in transmission with the gear of the upper cutter mechanism 1, thereby driving the connecting piece 1.1.3 in the upper cutter mechanism 1 to rotate. The connecting piece 1.1.3 is also eccentrically connected to the rotating shaft 1.1.1, so that the rotating shafts 1.1.1 of the upper cutter mechanism 1 and the lower cutter mechanism 2 rotate eccentrically simultaneously through one electric motor.

[0051] The cutting component 1.2 includes: a cutter 1.2.1, a guide rod 1.2.2, a floating seat 1.2.3, and a fixed seat 1.1.4. Among them, the fixed seat 1.1.4 is rectangular, the cutter 1.2.1 is rectangular, and its side surface is a cutting edge surface 1.2.1.1. The cutter 1.2.1 is arranged on the side surface of the fixed seat 1.2.4. The guide rod 1.2.2 penetrates through the top and bottom surfaces of the floating seat 1.2.3 so that the floating seat 1.2.3 is sleeved on the guide rod 1.2.2. The rotating shaft 1.1.1 is perpendicular to the guide rod 1.2.2 and penetrates through the front and rear surfaces of the floating seat 1.2.3.

[0052] Above, as Figure 4As shown, the guide rod 1.2.2 of the upper cutting knife mechanism 1 is fixed on the floating seat 1.2.3 of the lower cutting knife mechanism 2, and the guide rod 1.2.2 of the lower cutting knife mechanism 2 is fixed on the floating seat 1.2.3 of the upper cutting knife mechanism 1. The cutting knives 1.2.1 of the upper cutting knife mechanism 1 and the lower cutting knife mechanism 2 are respectively arranged on the inner side surfaces of their respective fixed seats 1.2.4. When the floating seat 1.2.3 of the upper cutting knife mechanism 1 moves downward and the floating seat 1.2.3 of the lower cutting knife mechanism 2 moves upward, the cutting knives 1.2.1 of the two can be arranged oppositely, so as to cut off the cutting target 3 arranged between the two cutting knives.

[0053] The beneficial effects brought by the technical solution provided by the embodiment of the present invention are as follows:

[0054] 1. In the present invention, the rotational motion of the motor output shaft is converted into the linear motion of the floating block along the guide shaft through the eccentric drive of the rotating shaft and the motor, so that the cutting mechanism has a non-stop cutting interval, which is beneficial to improving the cutting efficiency and the service life of the cutting device;

[0055] 2. The present invention includes two cutting knife mechanisms arranged up and down, and realizes the cutting function of the cutting target moving therebetween through the opposite movement of the two, which will not affect the movement of the cutting target on the production line and is beneficial to improving the production efficiency.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
