Description

Technical Field

[0001] This invention relates to the field of plastic weaving and processing technology, and more specifically to a spool cutter. Background Technology

[0002] Currently, manual wire cutters use a sliding shaft to guide the cutter along a straight line for cutting. However, this type of wire cutter still has the following shortcomings in practical use: Firstly, the start of the cutter and the clamping of the wire spool are independent of each other. Cutting can start even if the wire spool is not properly clamped, posing a significant safety hazard. Secondly, one end of the wire spool needs to be manually fixed during the cutting process. This not only increases the risk of hand injury due to the easy proximity of the hand to the cutter area, but also makes it difficult to ensure stability. The spool is prone to shaking or shifting during cutting, affecting the accuracy and integrity of a single cut. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a wire winding spool cutter to solve the technical problems of scattered operation steps and unstable wire winding spool fixation, resulting in insufficient safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] On one hand, a spool cutter is provided, including:

[0006] First installation area;

[0007] A push rod having a first support surface and configured to move in a controlled manner relative to the first mounting area;

[0008] The second installation area has a second support surface arranged opposite to the first support surface, for supporting the two opposite end faces of the winding drum;

[0009] The conversion structure includes a locking component and a cutting component. The locking component is movably disposed in the second mounting area to restrict or allow the cutting component to move relative to the second mounting area. The locking component is configured to be triggered by the push rod moving into the second mounting area and to release the restriction on the cutting component.

[0010] In one embodiment, the locking component includes:

[0011] A first slider is slidably disposed in the second mounting area. The sliding direction of the first slider is the same as that of the push rod, and the first slider is driven by the push rod.

[0012] A return member is disposed between the second mounting area and the first slider. When the first slider slides, the return member deforms and accumulates a rebound force that drives the first slider to return to its original position.

[0013] The second slider is slidably disposed in the second mounting area and connected to the first slider via a connecting rod, so as to slide the second slider in conjunction with the first slider when the first slider slides, and to restrict or allow the movement of the cutting assembly.

[0014] In one embodiment, the connection points between the connecting rod and the first slider and the second slider respectively form a first hinge point and a second hinge point.

[0015] In one embodiment, the sliding directions of the first slider and the second slider are perpendicular to each other.

[0016] In one embodiment, the second support surface is provided with a clearance hole through which the push rod can pass, and the first slider is provided with a guide rod, which is inserted into the clearance hole with a gap, so as to abut or separate from the push rod.

[0017] In one embodiment, the cutting assembly includes:

[0018] The cutter is configured to move in a controlled manner relative to the second mounting area;

[0019] A stop block is connected to the cutter and abuts against or separates from it when the second slider slides.

[0020] In one embodiment, the second mounting area is provided with a guide rail, and the cutter is slidably mounted on the guide rail.

[0021] In one embodiment, an elastic element is provided between the guide rail and the cutter. When the cutter slides, the elastic element deforms and accumulates an elastic force that drives the cutter to return to its original position.

[0022] In one embodiment, the first mounting area is provided with a drive member for pushing the push rod to move.

[0023] In one embodiment, a receiving port is provided between the first installation area and the second installation area.

[0024] Compared to existing technologies, this invention offers the following advantages: By setting a conversion structure to link the movement of the push rod with the unlocking action of the cutting component, an interlocking mechanism is achieved where cutting can only commence when the device is properly clamped. When the push rod is moved to the second installation area, its first support surface mates with the second support surface of the second installation area, jointly clamping the two opposite end faces of the wire winding drum. Simultaneously, the movement of the push rod triggers the locking component to release the restriction on the cutting component. In terms of safety, the cutting component is only allowed to move after the wire winding drum has been pushed to a reliably clamped state by the push rod, avoiding the possibility of the wire winding drum not being secured due to the independent operation of clamping and cutting. The system eliminates the safety hazard of accidental start-up of the cutting mechanism. Regarding operational safety, the automatic clamping of both ends of the wire winding drum via push rod movement replaces the manual fixing method, allowing operators to keep their hands away from the cutting area and reducing the risk of cuts. In terms of cutting stability, the cutting component is unlocked only after the push rod is in position, ensuring the wire winding drum remains stable throughout the cutting process. This solves the problems of skewed cutting trajectories and difficulty in achieving a single cut due to shaking or displacement during manual fixing. Finally, the combined clamping and unlocking actions simplify the operation and improve efficiency during batch processing. Attached Figure Description

[0039] The present invention will be further described in detail below through specific embodiments:

[0040] In embodiments of the present invention, such as Figures 1-2 As shown, the spool cutter includes: a first mounting area 1, a push rod 2, a second mounting area 3, and a conversion structure; the push rod 2 has a first support surface 201 and is configured to move in a controlled manner relative to the first mounting area 1; the second mounting area 3 has a second support surface 301 arranged opposite to the first support surface 201 for supporting two opposite end faces of the spool; the conversion structure includes a locking assembly 4 and a cutting assembly 5, the locking assembly 4 being movably disposed in the second mounting area 3 for restricting or allowing the cutting assembly 5 to move relative to the second mounting area 3, wherein the locking assembly 4 is configured to be triggered by the push rod 2 moving into the second mounting area 3 and releasing the restriction on the cutting assembly 5.

[0041] Specifically, in this embodiment of the invention, the mounting base includes a first mounting area 1 and a second mounting area 3 arranged opposite to each other, forming a cutting space between the two mounting areas for cutting the spool. Furthermore, since the spool has a hollow internal structure, a push rod 2 is provided in the first mounting area 1. This push rod 2 passes through the inside of the spool for initial positioning (of course, the diameter and shape of the push rod 2 can be adjusted adaptively according to the diameter and shape of the spool, and are not limited here). Simultaneously, the push rod 2 is provided with a push block, which is integrally formed with the push rod 2 and forms a first support surface 201 facing the second mounting area 3. Thus, when the spool is fitted onto the push rod 2, one end face abuts against the first support surface 201. In addition, to fix the spool before cutting, the push rod 2 can move relative to the first mounting area 1 under external force and gradually approach the second mounting area 3, so that the first support surface 201 and the second support surface 301 formed in the second mounting area 3 cooperate to clamp the spool between them. Conversely, as the push rod 2 gradually moves away from the second mounting area 3, the wire spool can be gradually released to facilitate unloading. Thus, the moving push rod 2 can transport the wire spool to the second mounting area 3, allowing the first support surface 201 and the second support surface 301 to clamp the wire spool together. This prevents the wire spool from shifting during cutting and eliminates the need for manual support to keep it away from the cutting area, thus avoiding scratches.

[0042] In this embodiment of the invention, the switching structure includes a locking component 4 and a cutting component 5. The locking component 4 is movably disposed in the second mounting area 3, enabling it to restrict or allow the cutting component 5 to move relative to the second mounting area 3. When the cutting component 5 is in a restricted state, it cannot move to the cutting space; conversely, when it is in a permitted state, it can move to the cutting space to cut the wire spool. To link the switching mechanism to the positioning of the wire spool, the cutting component 5 is only triggered to unlock after the wire spool is properly clamped, thereby improving the safety of the cutter.

[0043] Specifically, when the first support surface 201 and the second support surface 301 clamp the wire winding drum together, the end of the push rod 2 is located in the second installation area 3 and can trigger the locking component 4 to move, switching it from the locked state to the unlocked state, thereby releasing the restriction on the cutting component 5, and allowing the cutting component 5 to move under the action of external force to cut the wire winding drum during the clamping process.

[0044] This embodiment achieves axial and radial positioning of the wire winding drum through the cooperation of push rod 2, first support surface 201, and second support surface 301. This eliminates the need for manual fixing of the wire winding drum, avoiding proximity to the cutting area and reducing the risk of scratches. Simultaneously, once the wire winding drum is fixed in place, push rod 2 triggers the locking structure to unlock, allowing the cutting assembly 5 to move and cut the wire winding drum. During this process, the unlocking action of push rod 2 is linked to the locking structure, ensuring that cutting can only proceed after the wire winding drum is properly clamped. This interlocking mechanism enables the clamping and cutting to be synchronized, preventing safety hazards caused by accidental cutting when the wire winding drum is not fixed. Furthermore, combining the clamping and unlocking actions into one not only simplifies the operation but also improves the efficiency of batch operations.

[0045] like Figure 3 , Figure 4 As shown, in one embodiment, the locking assembly 4 includes: a first slider 401, a return member 402, and a second slider 403; the first slider 401 is slidably disposed in the second mounting area 3, the first slider 401 slides in the same direction as the push rod 2, and is driven by the push rod 2; the return member 402 is disposed between the second mounting area 3 and the first slider 401, and when the first slider 401 slides, the return member 402 deforms and accumulates a rebound force to drive the first slider 401 to reset its movement; the second slider 403 is slidably disposed in the second mounting area 3 and is connected to the first slider 401 by a connecting rod 404, so as to link the second slider 403 to slide when the first slider 401 slides, and to restrict or allow the movement of the cutting assembly 5.

[0046] Specifically, when the push rod 2 moves to the second mounting area 3, in order to trigger the locking component 4 to form an unlocked state, the locking component 4 in this embodiment includes a first slider 401, a second slider 403, and a connecting rod 404. The first slider 401 is slidably disposed in the second mounting area 3 along the pushing direction of the push rod 2. The second slider 403 is also slidably disposed in the second mounting area 3, but its sliding direction is perpendicular to the sliding direction of the first slider 401. One end of the second slider 403 is connected to the first slider 401 through the connecting rod 404, and its other end is used to restrict or allow the movement of the cutting component 5. Thus, when the push rod 2 continues to feed until it can push the first slider 401, the second slider 403 moves away from the cutting component 5 after being linked by the connecting rod 404, thereby releasing the cutting component 5. Of course, in order to ensure that the first slider 401 and the second slider 403 slide along the preset path, a corresponding slide rail is provided in the second mounting area 3; at the same time, the second mounting area 3 forms a cavity for installing the locking component 4, so as to prevent the cut wire from interfering with the movement of the corresponding slider.

[0047] Additionally, after cutting is completed, push rod 2 resets to unload the material, requiring relocking of the cutting assembly 5, which necessitates the reset of the second slider 403. For this purpose, the locking assembly 4 also includes a return member 402, located between the second mounting area 3 and the first slider 401. When the first slider 401 is pushed by push rod 2 and undergoes sliding displacement, the return member 402 deforms and accumulates a rebound force to reset the first slider 401. When push rod 2 disengages from the first slider 401, the return member 402 can pull the first slider 401 back to its initial position. During this process, the second slider 403 can be reset via connecting rod 404, thereby relocking the cutting assembly 5 at that location. Figure 4 As shown, the return element 402 in this embodiment is a spring, and two springs are provided to balance the force on the first slider 401.

[0048] Furthermore, such as Figure 4 As shown, in one embodiment, the connection points of the connecting rod 404 with the first slider 401 and the second slider 403 respectively form a first hinge point 405 and a second hinge point 406. Specifically, in order to make the first slider 401 slide and thus the second slider 403 slide in conjunction, in this embodiment, the connecting rod 404 has a first end and a second end arranged along its length direction. The first end of the connecting rod 404 is rotatably connected to the first slider 401 to form the first hinge point 405; similarly, the second end of the connecting rod 404 is rotatably connected to the second slider 403 to form the second hinge point 406. Thus, when the first slider 401 slides towards the second slider 403, the two hinge points of the connecting rod 404 rotate, pushing or pulling the second slider 403 to slide.

[0049] Furthermore, such as Figure 4 As shown, in one embodiment, the sliding directions of the first slider 401 and the second slider 403 are perpendicular to each other. Specifically, on the one hand, to enable the locking assembly 4 to switch between locked and unlocked states, and on the other hand, to save installation space; this embodiment sets the sliding directions of the first slider 401 and the second slider 403 to be perpendicular to each other, so that when the first slider 401 moves forward, the connecting rod 404 can push the second slider 403 to one side or pull the second slider 403 back to the other side, thereby achieving the restriction or release of the cutting assembly 5. At the same time, the sliding directions of the two sliders are perpendicular to each other, and they do not affect each other when sliding, and the installation area can be reduced to make the structure more compact. Of course, as Figure 4 As shown, the second slider 403 has an L-shaped structure to facilitate the installation of the connecting rod 404.

[0050] like Figures 1-4As shown, in one embodiment, the second support surface 301 is provided with a clearance hole 302 through which the push rod 2 can pass. The first slider 401 is provided with a guide rod 407, which is intermittently inserted into the clearance hole 302 to abut or separate from the push rod 2. Specifically, since the push rod 2 needs to extend into the cavity of the second mounting area 3 to trigger the sliding of the first slider 401, this embodiment provides a clearance hole 302 on the second support surface 301, allowing the push rod 2 to extend into the cavity through the clearance hole 302 when it is pushed to the second mounting surface, and to push the first slider 401 to move. At the same time, providing a clearance hole 302 on the second support surface 301 does not affect the clamping of the winding drum or the linkage mechanism of the push rod 2, so as to be compatible with the clamping and unlocking functions. Furthermore, to shorten the length of the push rod 2 and enable the first slider 401 to quickly respond to the pushing action of the push rod 2, this embodiment provides a guide rod 407 at the slider. The guide rod 407 is coaxially aligned with the push rod 2 and passes through the clearance hole 302. When the push rod 2 enters the clearance hole, it contacts the guide rod 407. Upon contact, the first slider 401 slides during the continuous pushing of the push rod 2, causing the second slider 403 to release the cutting assembly 5. Simultaneously, the movement of the guide rod 407 within the clearance hole 302, combined with the use of the return member 402, allows the first slider 401 to quickly reset.

[0051] like Figure 5 As shown, in one embodiment, the cutting assembly 5 includes: a cutter 501 and a stop 502; the cutter 501 is configured to move in a controlled manner relative to the second mounting area 3; the stop 502 is connected to the cutter 501 and abuts against or separates from it when the second slider 403 slides. Specifically, in order to enable the cutting assembly 5 to be blocked or released by the second slider 403, while also fulfilling the function of cutting the spool, this embodiment divides the cutting assembly 5 into a cutter 501 and a stop 502. The cutter 501 is pulled or pushed to cut the spool, and the stop 502, as part of the cutter 501, can be blocked or released by the second slider 403, thereby locking or unlocking the cutter 501 by restricting or releasing the stop 502. Figure 5 As shown, a bracket is provided to assemble the cutter 501 and the stop block 502 together. The cutter 501 is detachably connected to the bracket for easy maintenance or replacement. The stop block 502 is fixed to the bracket. Preferably, to accommodate the shape of the second slider 403, the stop block 502 has a T-shaped structure. One end of the second slider 403 is located at the connection between the horizontal and vertical sections of the stop block 502. The stop block 502 is blocked or released by the feed or retraction of the second slider 403. In addition, a handle is provided at the cutter 501 to facilitate pulling it.

[0052] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, the second mounting area 3 is provided with a guide rail 503, and the cutter 501 is slidably mounted on the guide rail 503. Specifically, in order to enable the cutter 501 to move back and forth in the cutting space, this embodiment provides a guide rail 503 in the second mounting area 3, so that the bracket for mounting the cutter 501 is slidably mounted on the guide rail 503. Pulling the handle will move the cutter 501 relative to the second mounting area 3 to cut the spool. Of course, to extend the movement path of the cutter 501, the guide rail 503 can extend to the first mounting area 1.

[0053] like Figure 5 As shown, in one embodiment, an elastic element 504 is provided between the guide rail 503 and the cutter 501. When the cutter 501 slides, the elastic element 504 deforms and accumulates an elastic force to drive the cutter 501 to reset. Specifically, when the cutter 501 is pulled from back to front (from the second mounting area 3 to the first mounting area 1) to cut the spool, the cutter 501 is released to automatically reset and is locked again by the locking component 4. In this embodiment, by providing an elastic element 504, the elastic element 504 accumulates an elastic force to drive the cutter 501 to reset when the cutter 501 slides. Thus, when the cutter 501 is released, the elastic force generated by the elastic element 504 can cause the cutter 501 to slide back to its initial position along the guide rail 503, and the second slider 403 restricts the movement of the stop 502 again. Of course, the elastic element 504 can be a spring, or in order to meet the need for the cutter 501 to move a longer distance, the elastic element 504 can be a spiral spring and be pulled to the cutter 501 by a traction rope.

[0054] like Figure 1 , Figure 2 and Figure 6 As shown, in one embodiment, the first mounting area 1 is provided with a driving member 6 to push the push rod 2 to move. Specifically, in order for the push rod 2 to move in a straight line, this embodiment uses a driving member 6 in the first mounting area 1 to drive the push rod 2 to move back and forth. Simultaneously, the driving member 6 must have a self-locking capability to ensure that the push rod 2 continuously abuts against the guide rod 407. Figure 6 As shown, the driving component 6 includes a hinged first connecting rod and a second connecting rod. The first connecting rod is hinged to the first mounting area 1, and the second connecting rod is hinged to the push rod 2. Pushing the first connecting rod will cause the second connecting rod to move, thereby feeding the push rod 2. Conversely, pulling the first connecting rod in the opposite direction will cause the push rod 2 to gradually exit the clearance hole 302. Alternatively, the driving component 6 can be a mating gear and rack structure, a slider and slide rail structure, or other linear drive structure.

[0055] like Figure 1 , Figure 2As shown, in one embodiment, a receiving port 7 is provided between the first installation area 1 and the second installation area 3. Specifically, the cut wire falls at the cutting space, i.e., at the first installation area 1 and the second installation area 3; therefore, this embodiment provides a receiving port 7 at this location to facilitate the waste material falling into the receiving port 7, thereby facilitating the separation of the wire from the roll and the recycling of the roll. Of course, a receiving box can be provided at the receiving port 7 to collect the aforementioned waste material.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
