Description

Technical Field

[0001] This utility model relates to gravity blanket production technology, specifically to a cutting device for producing gravity blankets that facilitates tensioning. Background Technology

[0002] Gravity blankets are functional fabrics that use the pressure generated by gravity to simulate the feeling of being hugged by filling the blanket with evenly distributed high-density particles (such as quartz sand, glass beads, etc.) inside the blanket body. They can relieve stress and help with sleep.

[0003] In the production process of gravity blankets, the cutting device is used to precisely cut the rolled gravity blanket blanks according to the design dimensions. It usually consists of a feeding mechanism, positioning components, cutting blades, and a receiving table. By replacing manual cutting with mechanized operation, the cutting dimensional accuracy of gravity blankets is ensured and production efficiency is improved.

[0004] In practical applications, existing cutting devices for gravity blanket production suffer from several drawbacks. Because gravity blankets are filled with high-density particles, the raw material is prone to localized sagging or wrinkling due to the weight of the particles in its natural state, and the fabric itself has a certain degree of elasticity. When the cutting device directly cuts this unstretched material, the contact point between the blade and the fabric is easily shifted due to the unevenness of the fabric, resulting in rough and irregular edges such as burrs and serrated notches. These irregular edges not only affect the visual appeal of the finished gravity blanket but may also lead to particle leakage due to edge wear during subsequent use, reducing product quality. Furthermore, manually trimming these irregular edges requires additional labor time, increasing production costs. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for producing gravity blankets that facilitates tensioning, in order to solve the problem of irregular cutting surfaces caused by the structure of gravity blankets in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for producing gravity blankets that facilitates tensioning, comprising a conveyor, a winding section provided on one side of the upper surface of the conveyor, a gravity blanket body wound around the outer surface of the winding section, a support frame provided at the middle position of the outer surface of the conveyor, a support shaft symmetrically and rotatably mounted on the bottom of the support frame, adjusting support plates fixedly connected to both sides of the outer surface of the support shaft, a fixed pressure plate fixedly mounted on the upper surface of the two adjusting support plates on the same side, and a pressing mechanism provided on the outer surface of the adjusting support plates for pressing the gravity blanket body onto the fixed pressure plate;

[0007] The clamping mechanism includes a second drive unit, which is fixedly installed at the middle position of the support shaft. A fixed frame is installed at the output end of the upper surface of the second drive unit. A connecting plate is fixedly installed at the top of the fixed frame. The front and rear ends of the connecting plate are sleeved on the outer surface of the adjusting support plate and fixed with an outer sleeve.

[0008] The outer surface of the support shaft is provided with a relative rotation component for controlling the tension of the gravity blanket body at the cutting position;

[0009] The upper surface of the equipment support is also provided with a cutting structure for cutting the main body of the gravity blanket.

[0010] Furthermore, the relative rotation assembly includes a gear, which is fixedly installed on the outer surface of the support shaft near the inner groove of the adjusting support plate. A first drive unit is provided on one side of the support shaft extending to the outside of the equipment bracket, and a tension sensor is provided on one side of the outer surface of the support shaft near the first drive unit.

[0011] Furthermore, the two gears have the same structural dimensions, and the teeth on the outer surfaces of the two gears interlock and mesh.

[0012] Furthermore, the cutting structure includes a cutting device, which is disposed on the upper surface of the device support. A guide groove is provided at the middle of the bottom end of the cutting device, and a cutting blade is movably disposed inside the guide groove.

[0013] Furthermore, the bottom surface of the fixed pressure plate is provided with several fixed grooves, and several limiting protrusions are fixedly connected to the upper surface of the connecting plate at positions corresponding to the fixed grooves. The bottom of the limiting protrusions extends into the interior of the fixed grooves, and the fixed grooves and limiting protrusions engage with each other.

[0014] Furthermore, a through hole is provided at the center of the top of the outer sleeve, and one side of the outer surface of the adjusting support plate is located in the through hole, with the adjusting support plate and the through hole fitting together.

[0015] Compared with the prior art, the cutting device for producing gravity blankets that facilitates tensioning, provided by this utility model, has the following beneficial effects:

[0016] 1. This utility model uses the second drive unit of the pressing mechanism to drive the connecting plate to rise along the adjusting support plate. With the engagement of the limiting protrusion and the fixing groove, the main body of the gravity blanket is tightly pressed between the fixed pressure plate and the connecting plate. This not only prevents the gravity blanket from sliding and shifting during the tightening and cutting process, but also ensures the stability of the pressing action through the fitting of the outer sleeve and the adjusting support plate, providing a solid foundation for subsequent tightening and cutting.

[0017] 2. This utility model uses gear meshing transmission of the relative rotation component to realize the relative rotation of the two support shafts under the drive of the first drive unit, so that the adjusting support plate moves synchronously in opposite directions to tighten the main body of the gravity blanket. At the same time, the tension sensor monitors the tension in real time and controls the rotation amplitude, accurately tightening the gravity blanket to a taut state without tearing it. This effectively solves the problem of rough and irregular cutting surface caused by the looseness of the blank in traditional cutting, and improves the flatness and aesthetics of the cutting edge.

[0018] 3. This utility model uses the cutting blade of the cutting structure to move along the guide groove to cut the tensioned gravity blanket body. Combined with the conveying function of the equipment conveyor, it realizes a continuous operation from feeding, pressing, tensioning to cutting. There is no need for manual tensioning and positioning, which reduces manual intervention, improves production efficiency, and avoids the extra time investment of manually trimming irregular edges, thus reducing production costs.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] Example 1:

[0029] This utility model provides a cutting device for producing gravity blankets that facilitates tensioning. It includes a conveyor 1, a winding part 2 is provided on one side of the upper surface of the conveyor 1, a gravity blanket body 3 is wound around the outer surface of the winding part 2, a support 4 is provided at the middle position of the outer surface of the conveyor 1, a support shaft 5 is symmetrically and rotatably installed at the bottom of the support 4, and an adjusting support plate 8 is fixedly connected to both sides of the outer surface of the support shaft 5. A fixing pressure plate 9 is fixedly installed on the upper surface of the two adjusting support plates 8 on the same side, and a pressing mechanism is provided on the outer surface of the adjusting support plate 8 for pressing the gravity blanket body 3 onto the fixing pressure plate 9.

[0030] The clamping mechanism includes a second drive unit 15, which is fixedly installed at the middle position of the support shaft 5. The second drive unit 15 is an electric telescopic rod. A fixed frame 14 is installed at the output end of the upper surface of the second drive unit 15. A connecting plate 12 is fixedly installed at the top of the fixed frame 14. The front and rear ends of the connecting plate 12 are sleeved on the outer surface of the adjusting support plate 8 and an outer sleeve 11 is fixedly connected. A through hole is opened in the middle of the top of the outer sleeve 11. One side of the outer surface of the adjusting support plate 8 is located in the through hole. The adjusting support plate 8 and the through hole are fitted together.

[0031] The bottom surface of the fixed pressure plate 9 is provided with several fixed grooves 10, and several limiting protrusions 13 are fixedly connected to the upper surface of the connecting plate 12 at the corresponding positions of the fixed grooves 10. The bottom of the limiting protrusions 13 extends into the interior of the fixed grooves 10, and the fixed grooves 10 and the limiting protrusions 13 engage with each other.

[0032] A relative rotation component is provided on the outer surface of the support shaft 5 to control the tension of the cutting position of the gravity blanket body 3;

[0033] The upper surface of the equipment support 4 is also provided with a cutting structure for cutting the main body 3 of the gravity blanket.

[0034] Working principle: The operator installs the take-up part 2, which contains the main body 3 of the gravity blanket, onto the corresponding side of the equipment conveyor 1, allowing the main body 3 of the gravity blanket to be conveyed by the equipment conveyor 1. Next, the second drive unit 15 (electric telescopic rod) is activated. The second drive unit 15 extends and pushes the fixed frame 14 upward. The fixed frame 14 drives the connecting plate 12 and the outer sleeve 11 to move upward along the outer surface of the adjusting support plate 8. During this process, the limiting protrusion 13 on the connecting plate 12 gradually approaches the fixing groove 10 on the bottom surface of the fixed pressure plate 9. When the through hole at the top of the outer sleeve 11 fits into the adjusting support plate 8, the limiting protrusion 13 is precisely inserted into the fixing groove 10, pressing the main body 3 of the gravity blanket between the fixed pressure plate 9 and the connecting plate 12. The friction force allows the main body 3 of the gravity blanket to rotate smoothly with the subsequent rotating components, preventing slippage.

[0035] Example 2:

[0036] This embodiment is basically the same as the previous embodiment, except that the relative rotation component includes a gear 6, which is fixedly installed on the outer surface of the support shaft 5 near the inner groove of the adjusting support plate 8. A first drive unit 7 is provided on one side of the single support shaft 5 extending to the outside of the equipment bracket 4. The first drive unit 7 is a self-locking servo motor. A tension sensor 16 is provided on one side of the outer surface of the single support shaft 5 near the first drive unit 7.

[0037] The two gears 6 have the same structural dimensions, and the teeth on the outer surfaces of the two gears 6 interlock and mesh.

[0038] Working principle: After the initial placement and pressing of the gravity blanket body 3 is completed, the first drive unit 7 (self-locking servo motor) is started. The single support shaft 5 rotates under the drive unit 7. Because the teeth on the outer surfaces of the two gears 6 are interlocked, the rotation of the support shaft 5 drives the other support shaft 5 to rotate synchronously in the opposite direction through the gear 6. During the rotation of the support shaft 5, the adjusting plate 8, the fixed pressure plate 9, etc. rotate accordingly to tighten the cutting position of the gravity blanket body 3. At the same time, the tension sensor 16 monitors the tension on the outer surface of the support shaft 5 in real time. When the tension reaches the preset value that makes the gravity blanket body 3 taut, the feedback signal controls the first drive unit 7 to adjust the rotation amplitude or stop the rotation to ensure that the gravity blanket body 3 is in a suitable taut state and avoids damage.

[0039] Example 3:

[0040] This embodiment is basically the same as the previous embodiment, except that the cutting structure includes a cutting device 17, which is set on the upper surface of the device support 4. A guide groove 18 is provided in the middle of the bottom end of the cutting device 17, and a cutting blade 19 is movably arranged inside the guide groove 18.

[0041] Working principle: After the pressing and tightening operation of the gravity blanket body 3 is completed, when the gravity blanket body 3 is taut and the position is adjusted, the cutting equipment 17 is started. The operator pushes the cutting blade 19 to move along the inside of the guide slide 18. The cutting blade 19 cuts the taut gravity blanket body 3 along the trajectory of the guide slide 18, thus completing the cutting process of gravity blanket production.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
