Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting device technology, and more specifically, to a mushroom-shaped hook and loop fastener cutting device. Background Technology
[0002] The mushroom-shaped hook and loop fastener consists of two plastic backing strips with mushroom-shaped plastic protrusions, known as "mushroom heads." Different mesh counts are available per square inch for these mushroom heads, commonly 170, 250, and 400 mesh; higher mesh counts result in greater closure strength. The mushroom heads can be fitted with different adhesive backings or left unbacked. When the two pieces of the hook and loop fastener are pressed together, the mushroom heads lock together, forming a secure connection and producing a snapping sound, allowing for quick fastening. To separate, the two pieces can be easily peeled apart from the mushroom heads, allowing for disassembly. It can be opened and closed repeatedly up to 1000 times.
[0003] Existing mushroom snap production methods require cutting the rolled mushroom strips into corresponding lengths. Most existing cutting devices rely on manual measurement for length determination, which results in poor precision and affects the production quality of standardized, uniform mushroom strips. Therefore, we propose a mushroom snap cutting device. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a mushroom-shaped hook and loop fastener cutting device to solve the technical problems of poor accuracy of manual measurement and inconsistent cut lengths and poor quality of finished products in the current cutting process.
[0005] To solve the above technical problems, this utility model provides the following technical solution: a mushroom snap-on cutting device, including a mushroom strip, a base, a cutting mechanism, and a rotating mechanism. The rotating mechanism is rotatably installed on the front side of a back plate. The rotating mechanism consists of a positioning cylinder and a rear cover. The rear end of the positioning cylinder is fixed in the middle of the rear cover. An inner cylinder is fixed inside the positioning cylinder. An adjustment mechanism is provided at the front end of the inner cylinder. Outer covers are provided on the upper and lower sides of the front opening of the positioning cylinder, and the outer covers are connected to the adjustment mechanism. After the mushroom strip is rolled up, it is sleeved on the outside of the positioning cylinder. The bottom of the back plate is installed on the base. There are two cutting mechanisms, and the two cutting mechanisms are slidably installed at both ends of the adjustment groove on the base. The cutting mechanism consists of an adjustment seat and an outer frame. An outer cover is provided at the upper front end of the back plate, and the outer cover is adapted to the upper side of the mushroom strip.
[0006] When in use, this utility model is powered by an external power source. The operator starts the device through an external control device, which activates the rear-mounted motor to drive the rotating mechanism. The rotating mechanism drives the mushroom-shaped belt, which is wound up and fitted onto the outside of the positioning cylinder, to rotate. The mushroom-shaped belt end is manually pulled and guided to the inner side of the outer frame of the cutting mechanism. Based on the encoder control system, the encoder records the motor rotation data and calculates the conveying length of the mushroom-shaped belt. Once the set length is reached, the cutting is precisely controlled to ensure that the cutting length is consistent each time. The device has cutting mechanisms on both sides, which can be processed according to the different positions of the forward and reverse winding output ends of the mushroom-shaped belt. At the same time, the distance of the cutting mechanism is adjustable, and the displacement of the arc pressure surface of the adjustment seat is adjusted according to the thickness of the mushroom-shaped belt. When the thickness of the mushroom-shaped belt decreases due to continuous release, the adjustable position design makes the arc pressure surface correspond to the mushroom-shaped belt, and the electric telescopic rod is activated to drive the outer frame to retract. The cutting blade cuts the mushroom-shaped belt. Through the above structural design, the device can perform precise cutting to ensure the quality of the finished product. At the same time, the cutting components are provided in both directions, which facilitates processing according to the winding direction of the mushroom-shaped belt and makes it highly operable.
[0007] Preferably, the positioning cylinder has a ring array of limiting rods at its front end opening, the outer cover has an arc-shaped structure, and both ends of the inner side of the outer cover have vertical limiting grooves, with the outer ends of the limiting rods slidably installed in the limiting grooves.
[0008] Preferably, the inner cylinder has front slots on both sides of its front end. The adjustment mechanism consists of a slider and a linkage arm. The slider is slidably installed in the front slot. There are two sets of linkage arms, and the inner and outer ends of the linkage arms are scissor-shaped and are connected to the outer cover and the slider by hinges.
[0009] Preferably, the outer cover and the rear cover are respectively attached to the front and rear end faces of the mushroom strip, and the output end of the mushroom strip is guided to the inner side of the outer frame of the cutting mechanism.
[0010] Preferably, an outer frame is slidably mounted on the outer side of the adjusting seat, and the sliding end of the outer frame is connected to the adjusting seat slot via an electric telescopic rod. A cutting blade is embedded in the middle of the outer frame.
[0011] Preferably, the inner side of the adjusting seat is provided with an arc-shaped surface, and the arc-shaped surface is adapted to the size of the positioning cylinder, and the outer side of the upper end of the adjusting seat is provided with an arc-shaped pressure surface.
[0012] Preferably, both the adjusting groove and the front groove are provided with lead screws, and the lead screws are threaded through the bottom sliding end of the adjusting seat and the inner end of the slider, respectively.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the design of a rotating mechanism, uses a manual traction guide at the mushroom belt end to guide the inner side of the outer frame of the cutting mechanism. Based on an encoder-based control system, the encoder records motor rotation data, calculates the conveying length of the mushroom belt, and precisely controls the cutting after reaching the set length, ensuring consistent cutting length each time. The device has cutting mechanisms on both sides, which can be processed according to the different positions of the forward and reverse winding output ends of the mushroom belt. At the same time, the distance of the cutting mechanism is adjustable, and the displacement of the arc pressure surface of the adjustment seat is adjusted according to the thickness of the mushroom belt. When the continuous release causes the thickness of the mushroom belt to decrease, the adjustable position design makes the arc pressure surface correspond to the mushroom belt. Through the above structural design, the device can perform precise cutting, ensuring the quality of the finished product. At the same time, cutting components are provided in both directions, which facilitates processing according to the winding direction of the mushroom belt, making it highly operable.
[0015] 2. This utility model also incorporates an adjustment mechanism. The mushroom strip is fitted onto the outside of the positioning cylinder. During continuous rotation, if the mushroom strip's winding tension is poor and it is prone to loosening, the outer cover and rear cover shield the cross-section of the mushroom strip. Simultaneously, the outer cover prevents the mushroom strip from unraveling during rotation. When the mushroom strip roll is exhausted, the screw thread inside the front slot drives the slider to move. The slider pulls the outer cover via the linkage arm, and both ends of the outer cover are simultaneously pulled inward to complete the closure. The outer cover is limited by the limiting rod to maintain vertical lifting. At this time, the positioning cylinder port facilitates the installation of the wound mushroom strip, making feeding easier. Simultaneously, after closure, the wound mushroom strip is shielded to prevent loosening. Attached Figure Description

The outer ends of the limiting rods 506 are slidably installed in the limiting grooves. Front grooves 505 are provided on both sides of the front end of the inner cylinder 504. The adjusting mechanism 6 consists of a slider 601 and a linkage arm 602. The slider 601 is slidably installed in the front groove 505. Two sets of linkage arms 602 are provided, and the inner and outer ends of the linkage arms 602 are hinged. The chain rotates to connect the outer cover 501 and the slider 601. The outer cover 501 and the rear cover 503 respectively fit the front and rear end faces of the mushroom belt 2. The output end of the mushroom belt 2 is guided to the inner side of the outer frame 402 of the cutting mechanism 4. The end of the mushroom belt 2 is manually pulled and guided to the inner side of the outer frame 402 of the cutting mechanism 4. The control system is based on an encoder. The encoder records the motor rotation data and calculates the conveying length of the mushroom belt 2. After reaching the set length, the cutting is precisely controlled to ensure that the cutting length is consistent each time. The device is equipped with cutting mechanisms 4 on both sides, which can be processed according to the different positions of the forward and reverse winding output ends of the mushroom belt 2. At the same time, the distance of the cutting mechanism 4 is adjustable. The displacement of the arc pressure surface 405 of the adjusting seat 401 is adjusted according to the thickness of the mushroom belt 2. When the thickness of the mushroom belt 2 decreases due to continuous release, the arc pressure surface 405 is aligned with the mushroom belt 2 through the adjustable position design. Through the above structural design, the device can perform precise cutting to ensure the quality of the finished product. At the same time, cutting components are provided in both directions to facilitate processing according to the winding direction of the mushroom belt 2, making it highly operable.
[0023] like Figures 2 to 5As shown, this utility model relates to a mushroom snap-on cutting device, including a mushroom strip 2, a base 3, a cutting mechanism 4, and a rotating mechanism 5. After the mushroom strip 2 is rolled up, it is sleeved on the outside of the positioning cylinder 502. The bottom of the back plate 1 is installed on the base 3. There are two cutting mechanisms 4, and the two cutting mechanisms 4 are slidably installed at both ends of the adjusting groove 301 on the base 3. The cutting mechanism 4 is composed of an adjusting seat 401 and an outer frame 402. The upper front end of the back plate 1 is provided with an outer cover 101, and the outer cover 101 is adapted to the upper side of the mushroom strip 2. The outer frame 402 is slidably installed on the outside of the adjusting seat 401, and the sliding end of the outer frame 402 is connected to the groove of the adjusting seat 401 through an electric telescopic rod 404. A cutting blade 403 is embedded in the middle of the outer frame 402. The inner side of the adjusting seat 401 is provided with an arc-shaped surface, and the arc-shaped surface is adapted to the size of the positioning cylinder 502. The upper outer side of the adjusting seat 401 is provided with an arc-shaped pressing surface 405. The adjusting groove 3 Both 01 and the front slot 505 are equipped with lead screws, which are threaded through the bottom sliding end of the adjusting seat 401 and the inner end of the slider 601, respectively. The mushroom strip 2 is sleeved on the outside of the positioning cylinder 502. During continuous rotation, if the tension of the mushroom strip 2 is poor, it is easy to loosen. The outer cover 501 and the rear cover 503 cover the cross section of the mushroom strip 2. At the same time, the outer cover 101 prevents the mushroom strip 2 from unraveling during rotation. When the mushroom strip 2 is consumed, the lead screw inside the front slot 505 drives the slider 601 to move. The slider 601 pulls the outer cover 501 through the linkage arm 602. The two ends of the outer cover 501 are pulled inward simultaneously to complete the closure. The outer cover 501 is limited by the limiting rod 506 to maintain vertical lifting. At this time, the port of the positioning cylinder 502 is convenient for the sleeve installation of the wound mushroom strip 2, which is convenient for the feeding operation.

[0024] Working Principle: This embodiment provides a mushroom-shaped hook and loop fastener cutting device. In use, it is powered by an external power source. The operator starts the device via an external control device. The motor behind the back plate 1 drives the rotating mechanism 5 to rotate. The rotating mechanism 5 drives the mushroom-shaped strap 2, which is wound up and fitted onto the outside of the positioning cylinder 502, to rotate. The end of the mushroom-shaped strap 2 is manually pulled and guided to the inner side of the outer frame 402 of the cutting mechanism 4. Based on an encoder-based control system, the encoder records the motor rotation data and calculates the conveying length of the mushroom-shaped strap 2. Once the set length is reached, precise cutting is controlled to ensure consistent cutting length each time. The device has cutting mechanisms 4 on both sides, which can perform corresponding processing according to the different positions of the forward and reverse winding output ends of the mushroom-shaped strap 2. The distance of the cutting mechanism 4 is adjustable. The displacement of the arc-shaped pressure surface 405 of the adjusting seat 401 is adjusted according to the thickness of the mushroom-shaped strap 2. When continuous release causes the thickness of the mushroom-shaped strap 2 to decrease... When the adjustable position design aligns the arc-pressed surface 405 with the mushroom strip 2, the electric telescopic rod 404 is activated to retract the outer frame 402, and the cutting blade 403 cuts the mushroom strip 2. The mushroom strip 2 is then fitted onto the outside of the positioning cylinder 502. During continuous rotation, if the mushroom strip 2 has poor winding tension and is prone to loosening, the outer cover 501 and the rear cover 503 are used to shield the cross-section of the mushroom strip 2. At the same time, the outer cover 101 is used to prevent the mushroom strip 2 from unraveling during rotation. When the mushroom strip 2 is completely consumed, the screw thread inside the front slot 505 is activated to drive the slider 601 to move. The slider 601 pulls the outer cover 501 through the linkage arm 602. The two ends of the outer cover 501 are simultaneously pulled inward to complete the closure. The outer cover 501 is limited by the limiting rod 506 to maintain vertical lifting. At this time, the port of the positioning cylinder 502 is convenient for winding and fitting the mushroom strip 2.
