[0009] Furthermore, the cutting device with protective function includes: a second rotating bracket, one end of which is mounted with a cutting blade near the product, and the other end of which is rotatably arranged around a second preset axis to drive the cutting blade to move closer to or away from the product; and a second driving assembly, which is drivenly connected to the second rotating bracket to drive the second rotating bracket to rotate around the second preset axis.

[0010] Furthermore, the second drive assembly includes: a second pulley group, the second pulley group including at least two pulleys, wherein the second pulley group includes a second pulley, the axis of the second pulley is arranged along a second preset axis, and the second pulley is fixedly connected to the second rotating bracket; a second belt, the second belt being wound around the second pulley group; and a second drive component, the second drive component being drivenly connected to the second belt or the second pulley group to drive the second pulley to rotate.

[0011] Furthermore, the second rotating bracket includes: a first support member and a second support member disposed opposite to each other, the first support member and the second support member being spaced apart along a second preset axis; a mounting base, the two ends of the mounting base being connected to the first support member and the second support member respectively, the extension direction of the mounting base being consistent with the extension direction of the cutting blade, the cutting blade being fixedly mounted on the mounting base, and the cutting blade being able to extend out of the mounting base and abut against the material strip.

[0012] Furthermore, the cutting device with protective function includes: a first conveying roller, which is located at the output end of the material conveying roller group, guides the material strip onto the product, and when the cutting blade cuts the material strip, the cutting blade is located between the first conveying roller and the protective component; a first fixed shaft, the extension direction of the first fixed shaft is parallel to the extension direction of the cutting blade, and the first conveying roller is rotatably mounted on the first fixed shaft.

[0015] Beneficial effects:

[0016] 1. Specifically, the protective component extends parallel to the cutting blade. It is positioned on the side of the cutting blade closest to the product, maintaining a certain distance from it to create an effective shielding area on the product surface. The protective component isolates the cutting blade from the product, mechanically preventing contact between them. When the cutting blade cuts the material strip, the protective component, through its physical blocking effect on the product side, prevents the cutting blade or its movement trajectory from directly contacting the product, thus avoiding product damage caused by the cutting action. Furthermore, the movable design of the protective component allows for automatic or manual adjustment of its distance from the tire according to product specifications, ensuring a relatively consistent positional relationship with the tire.

[0017] 2. The protective component is movably positioned relative to the product, allowing it to move closer to or further away from the product depending on the cutting blade's movement. That is, before cutting, the protective component must be in position before the cutting blade can begin cutting. This invention, by setting the protective component and placing it on the side of the cutting blade closest to the product while maintaining a distance from the cutting blade, mechanically prevents contact between the cutting blades. Applying this protective cutting device to the tire packaging process achieves active isolation and protection of the tire surface while cutting the tape, improving the safety and yield of the packaging process. It solves the technical problem in related technologies where the tape cutting process easily damages the tire during packaging.

[0018] 3. By adjusting the airflow rate of the second cylinder, the rotation speed of the second rotating bracket is adjusted, thereby achieving a neat, burr-free cross-section of the material strip. Applying the protective cutting device in this embodiment to the tire packaging process can ensure that the cross-section of the tape is burr-free, thus guaranteeing the aesthetics of the tire packaging.

[0019] 4. The first conveying roller, the first pulley and the second pulley are collinear, that is, the first preset axis and the second preset axis are collinear. This can reduce the space occupied by the rotation process of the first rotating bracket and the second rotating bracket. The movement trajectories of the first rotating bracket and the second rotating bracket form concentric circles with the same center but different radii, so they will not interfere with each other. At the same time, it can save space and reduce the overall installation space of the cutting device with protective function. Attached Figure Description

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

[0027] According to an embodiment of this utility model, a cutting device with protective function is provided. Please refer to [link / reference]. Figures 1 to 4 The device includes: a cutting blade 1, which is movably disposed for cutting the material strip connected to the product; and a protective component 2, the extension direction of which is parallel to the extension direction of the cutting blade 1, the protective component 2 being disposed on the side of the cutting blade 1 closer to the product, and the protective component 2 being spaced apart from the cutting blade 1; wherein the protective component 2 is movably disposed relative to the product so as to move closer to or further away from the product depending on the operating state of the cutting blade 1.

[0028] Specifically, the cutting blade 1 is used to cut the strip connected to the product to separate the product from the strip. The extension direction of the cutting blade 1 is reasonably set according to the product shape and the direction of the strip to ensure that the cutting blade 1 can effectively cut into the strip. Preferably, the extension direction of the cutting blade is consistent with the width direction of the strip.

[0029] In some embodiments, the protective component 2 is a roller, i.e. a protective roller, which can be rotatably set. On the one hand, it reduces the frictional force when in contact with the product or the material strip. On the other hand, during the packaging process, the protective component 2 contacts the material strip on the surface of the product and can also play the role of smoothing the material strip.

[0030] Specifically, the extension direction of the protective component 2 is parallel to the extension direction of the cutting blade 1. Simultaneously, the protective component 2 is positioned on the side of the cutting blade 1 closest to the product, maintaining a certain distance from it, forming an effective shielding area on the product surface. The function of the protective component 2 is to isolate the cutting blade 1 from the product, mechanically preventing contact between the two blades. When the cutting blade 1 cuts the material strip, the protective component 2, through its physical blocking effect on the product side, prevents the cutting blade 1 or its movement trajectory from directly contacting the product, thereby avoiding product damage caused by the cutting action. Furthermore, the movable design of the protective component 2 allows for automatic or manual adjustment of its distance from the tire according to product specifications, ensuring a relatively consistent positional relationship with the tire.

[0031] In this invention, the protective component 2 is movably positioned relative to the product, allowing it to move closer to or further away from the product depending on the movement of the cutting blade 1. That is, before cutting, the protective component 2 must be in position before the cutting blade 1 can begin cutting. By setting the protective component 2 and positioning it on the side of the cutting blade 1 closest to the product, while maintaining a distance from the cutting blade 1, this invention mechanically prevents contact between the cutting blade 1 and the product. Applying this protective cutting device to the tire packaging process achieves active isolation and protection of the tire surface while cutting the tape, improving the safety and yield of the packaging process. This solves the technical problem in related technologies where the tape cutting process during tire packaging easily causes tire damage.

[0032] In the cutting device with protective function in this embodiment, see... Figure 1 The cutting device with protective function includes: a first rotating bracket 3, with a protective component 2 installed at one end of the first rotating bracket 3 near the product, and the other end of the first rotating bracket 3 rotatably arranged around a first preset axis to drive the protective component 2 closer to or away from the product; and a first driving assembly 4, which is drivenly connected to the first rotating bracket 3 to drive the first rotating bracket 3 to rotate around the first preset axis. Thus, by controlling the first rotating bracket 3 to reciprocate, the first driving assembly 4 drives the protective component 2 closer to or away from the product. When the protective component 2 approaches the product, it reaches a preset position, effectively shielding the product surface. At this time, the cutting blade can perform the action of cutting the material strip. When it moves away from the product, the first driving assembly 4 reverses its action, causing the first rotating bracket 3 to drive the protective component 2 back to its original position, preparing for the next cutting operation.

[0033] In the cutting device with protective function in this embodiment, see... Figure 1 The first drive assembly 4 includes: a first pulley group, which includes at least two pulleys, wherein the first pulley group includes a first pulley 41, the axis of which is arranged along a first preset axis, and the first pulley 41 is fixedly connected to the first rotating bracket 3; a first belt 42, which is wound around the first pulley group; and a first drive component 43, which is drivenly connected to the first belt 42 or the first pulley group to drive the first pulley 41 to rotate. By driving the first pulley group or the first belt 42 to move, the first pulley 41 is driven to rotate, thereby driving the first rotating bracket 3 to rotate around the first preset axis.

[0034] In the cutting device with protective function in this embodiment, see... Figure 1 The first driving component 43 includes a first cylinder. The extension direction of the telescopic arm of the first cylinder is the same as the extension direction of the first belt 42. A belt clamping component is installed on the telescopic arm of the first cylinder, and the belt clamping component clamps onto the first belt 42. By using a cylinder as the driving component, when the telescopic arm of the cylinder extends, it can drive the first belt 42 to rotate, thereby driving the first pulley 41 to rotate, and driving the first rotating bracket 3 to swing.

[0035] It should be noted that the rotation speed of the first rotating bracket 3 is adjusted by regulating the airflow rate of the first cylinder.

[0036] In the cutting device with protective function in this embodiment, see... Figure 1 The cutting device with protective function includes: a second rotating bracket 5, with a cutting blade 1 mounted at one end of the second rotating bracket 5 near the product, and the other end of the second rotating bracket 5 rotatably arranged around a second preset axis to drive the cutting blade 1 closer to or away from the product; and a second driving assembly 6, which is drivenly connected to the second rotating bracket 5 to drive the second rotating bracket 5 to rotate around the second preset axis. Thus, by controlling the reciprocating swing of the second rotating bracket 5 through the second driving assembly 6, the cutting blade 1 is driven closer to or away from the product. When the cutting blade 1 approaches the product, it performs a cutting action on the material strip; when it moves away from the product, the second driving assembly 6 reverses its action, causing the second rotating bracket 5 to drive the cutting blade 1 back to its original position, preparing for the next cutting operation.

[0037] It can be understood that while the cutting blade 1 achieves controllable movement through the second rotating bracket 5, the protective component 2 is also synchronously adjusted through the first rotating bracket 3. Both are controlled by independent drive components. Before the cutting action begins, the protective component 2 reaches the protective position before the cutting blade 1, forming an effective shielding of the product surface; then the cutting blade 1 performs the cutting action, ensuring that the entire cutting process is safe and reliable.

[0038] It is understandable that the first preset axis and the second preset axis are parallel to each other.

[0039] In some embodiments, the first preset axis and the second preset axis are collinear.

[0040] In the cutting device with protective function in this embodiment, see... Figure 1 The second drive assembly 6 includes: a second pulley group, which includes at least two pulleys, wherein the second pulley group includes a second pulley 61, the axis of which is arranged along a second preset axis, and the second pulley 61 is fixedly connected to the second rotating bracket 5; a second belt 62, which is wound around the second pulley group; and a second drive component 63, which is drivenly connected to the second belt 62 or the second pulley group to drive the second pulley 61 to rotate. By driving the second pulley group and the second belt 62, the second rotating bracket 5 is driven to rotate around the second preset axis.

[0041] In the cutting device with protective function in this embodiment, the second drive assembly 6 includes a second cylinder. The extension direction of the telescopic arm of the second cylinder is the same as the extension direction of the second belt 62. A belt clamping component is installed on the telescopic arm of the first cylinder, and the belt clamping component clamps onto the second belt 62. Using a cylinder as the drive component, when the telescopic arm of the cylinder extends, it drives the second belt 62 to rotate, thereby driving the second pulley 61 to rotate, and driving the second rotating bracket 5 to swing.

[0042] It should be noted that the rotation speed of the second rotating bracket 5 is adjusted by regulating the airflow rate of the second cylinder, thereby achieving a neat and burr-free cross-section of the material strip. Applying the protective cutting device in this embodiment to the tire packaging process can ensure that the cross-section of the tape is burr-free, thus guaranteeing the aesthetics of the tire packaging.

[0043] In the cutting device with protective function in this embodiment, see... Figure 2The second rotating bracket 5 includes: a first support member 51 and a second support member 52 arranged opposite to each other, the first support member 51 and the second support member 52 being spaced apart along a second preset axis; and a mounting base 53, the two ends of which are respectively connected to the first support member 51 and the second support member 52, the extending direction of the mounting base 53 being consistent with the extending direction of the cutting blade 1, the cutting blade 1 being fixedly mounted on the mounting base 53, and the cutting blade 1 being able to extend out of the mounting base 53 and abut against the material strip. By including the first support member 51 and the second support member 52 arranged opposite to each other, and the mounting base 53 connecting the two, a stable and flexible support for the cutting blade 1 is achieved.

[0044] Specifically, the blade body of the cutting blade is fixedly mounted on the mounting base 53, and the blade body of the cutting blade is in close contact with the mounting base 53, while the cutting edge extends out of the mounting base 53 and abuts against the material strip.

[0045] In the cutting device with protective function in this embodiment, see... Figure 3-4 The cutting device with protective function includes: a first conveyor roller 71, located at the output end of the material conveyor roller group, which guides the material strip onto the product. When the cutting blade 1 cuts the material strip, the cutting blade 1 is located between the first conveyor roller 71 and the protective component 2; and a first fixed shaft 8, whose extension direction is parallel to the extension direction of the cutting blade 1. The first conveyor roller 71 is rotatably mounted on the first fixed shaft 8. With the cutting blade 1 located between the first conveyor roller 71 and the protective component 2, the first conveyor roller 71 can support the material strip during cutting by the cutting blade 1, thereby ensuring the cutting effect.

[0046] Specifically, the cutting device with protective function includes a strip conveyor roller assembly for conveying the strip to the product, the strip conveyor roller assembly including an output end that is close to the product.

[0047] In the cutting device with protective function in this embodiment, see... Figure 1 A first pulley 41 and a second pulley 61 are rotatably mounted on the first fixed shaft 8. The first conveying roller 71, the first pulley 41, and the second pulley 61 are spaced apart along the axial direction of the first fixed shaft 8. In this way, the axes of the first conveying roller 71, the first pulley 41, and the second pulley 61 are collinear, that is, the first preset axis and the second preset axis are collinear. This can reduce the space occupied by the rotation process of the first rotating bracket 3 and the second rotating bracket 5. The movement trajectories of the first rotating bracket 3 and the second rotating bracket 5 form concentric circles with the same center but different radii, so they will not interfere with each other. At the same time, it can save space and reduce the overall installation space of the cutting device with protective function.

[0048] In the cutting device with protective function in this embodiment, see... Figure 4The cutting device with protective function includes an anti-rotation component, which comprises: an abutment member 91, which abuts against the second conveyor roller 72 in the material conveyor roller group; and a third drive member 92, the telescopic arm of which is connected to the abutment member 91. The third drive member 92 drives the abutment member 91 to move closer to or away from the second conveyor roller 72. By setting the anti-rotation component, the second conveyor roller 72 is prevented from rotating and causing the material belt to retract. During or after the cutting process, the third drive member 92 drives the abutment member 91 to move closer to the second conveyor roller 72, thereby abutting against the second conveyor roller 72 and preventing it from rotating. This keeps the material belt taut, ensuring smooth cutting and guaranteeing the next cutting operation.

[0049] In some embodiments, the cutting device with protective function further includes a base for mounting the cutting blade 1, the protective component 2, and the material conveying roller group, and at least one drive system for driving the base to move. By setting at least one drive system, the overall movement of the base can be controlled, and the cutting device with protective function can be controlled to move closer to or further away from the product loading and unloading position, which can facilitate product loading and unloading, or loading of material belts, etc.

[0050] In some embodiments, at least one drive system includes a first drive system that controls the base to move axially along the first conveying roller 71, and a second drive system and a third drive system that control the base to move in a direction closer to or farther from the product. By providing two drive systems in the same direction, the travel distance of the base in the direction closer to or farther from the product can be extended, thereby facilitating the matching of various products of different specifications and improving the packaging efficiency of the products.

[0051] In some embodiments, the cutting device with protective function further includes a sensing device for identifying the position of the product or strip, or identifying whether the protective component is in contact with the protective component 2, and adjusting the working position of the cutting blade or the protective component 2 according to the sensing result.

[0052] It is understood that the protective cutting device in this embodiment can be applied not only to the cutting of tape during tire packaging, but also to the cutting of materials such as cord fabric during the production of semi-finished tires. This device effectively avoids damage to the tire body during the cutting process. Furthermore, this cutting device can be extended to other non-tire-related fields, demonstrating broad technical adaptability and application prospects.

[0053] When the protective cutting device in this embodiment is applied to the tire packaging process to cut the tape, the working process is as follows:

[0054] 1. First, before the material strip is attached to the tire, the first rotating bracket 3 and the second rotating bracket 5 are both in the initial position. At this time, the protective component 2 is set away from the product by the first rotating bracket 3, while the cutting blade 1 is also kept away from the product by the second rotating bracket 5.

[0055] 2. After packaging begins, the protective cutting device moves and approaches the loaded tire, conveying the tape to the product. It works in conjunction with the tire packaging equipment to attach the tape to the tire. At the same time, according to the specific size of the product to be processed and the position of the tape, the first drive assembly 4 adjusts the position of the first rotating bracket 3 so that the protective component 2 is in a protective position, providing a safety guarantee for subsequent cutting operations.

[0056] 3. After the tape is wrapped, it needs to be cut. The second drive assembly 6 is activated, causing the second rotating bracket 5 to drive the cutting blade 1 along a preset trajectory toward the product, and finally cut into the tape to complete the cutting operation. During this process, the protective component 2 effectively isolates the cutting blade 1 from the product surface, preventing any possible physical contact or damage.

[0057] 4. After cutting, the protective cutting device moves away from the tire, and the second drive assembly 6 reverses its operation, causing the second rotating bracket 5 to quickly return the cutting blade 1 to its initial position, ready for the next operation. At the same time, the first drive assembly 4 also drives the first rotating bracket 3 to move the protective component 2 away from the vicinity of the product, restoring it to its original safe distance.
