Description

Technical Field

[0001] This utility model relates to the technical field of spreading devices, specifically a device for uniformly spreading material for summer cooling blankets on slopes. Background Technology

[0002] As a common summer bedding item, the core quality of summer quilts depends on the evenness of the filling material (such as down, polyester fiber, silk, etc.). Uneven distribution of the filling material can easily lead to problems such as localized clumping and significant differences in thickness, which not only reduces the fluffiness and comfort of the quilt but also affects its warmth, breathability, and lifespan. In the industrial production of summer quilts, the spreading of the filling material is a crucial process. Currently, there are two main technical solutions in the industry, both of which have significant drawbacks. Existing mechanical devices often use cylinders or motors to directly drive the pressure plate downwards for spreading. The pressure plate drive structure lacks a stable guiding mechanism, making it prone to tilting during the pressing process, resulting in uneven force on the filling material and further exacerbating the spreading differences. Pressure control is unbalanced: without an effective buffering mechanism, the pressure plate directly acts on the filling material, easily leading to excessive pressure causing compaction and clumping, or insufficient pressure resulting in inadequate spreading. Therefore, improvements to existing technologies are needed. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: A summer quilt slope filling uniform spreading device includes a spreading machine body 1. A spreading frame 2 is mounted on the upper end of the spreading machine body 1. A forming mechanism 3 is mounted on the upper end of the spreading frame 2. A summer quilt spreading frame 4 is mounted at the center of the upper end of the spreading machine body 1. A spreading cavity 5 is mounted inside the summer quilt spreading frame 4. The forming mechanism 3 includes an electric push rod 11 installed at the center of the upper end of the spreading frame 2. A drive plate 7 is mounted at the bottom end of the spreading frame 2. The drive plate 7 is connected to the drive end of the electric push rod 11. A spreading pressure plate 8 is mounted at the bottom end of the drive plate 7. A buffer assembly is mounted between the spreading pressure plate 8 and the drive plate 7.

[0019] In the specific implementation process, the spreading machine body 1 serves as the basic load-bearing structure of the entire device, ensuring the overall stability of the device during operation. The spreading frame 2 is fixed to the upper end of the spreading machine body 1 by welding, forming an upper support frame and providing an installation benchmark for the forming mechanism 3. The size of the summer quilt spreading frame 4 is adapted to the specifications of the summer quilt to be processed. Its inner sidewall can be coated with a smooth coating to reduce friction between the edges of the summer quilt and the frame, avoiding fabric wear. The spreading cavity 5 is a closed space for spreading the summer quilt filling material. During use, the summer quilt blank to be filled is laid flat in the spreading cavity 5. The uniform distribution of the filling material is achieved through the action of the forming mechanism 3. The forming mechanism 3 is the core driving part of the device. The electric push rod 11 is a servo electric push rod, which can adjust the thrust and stroke through the control system to meet the requirements. The spreadability requirements of summer quilts of different thicknesses are met; the drive plate 7 is made of aluminum alloy, which combines lightweight and structural strength. It is rigidly connected to the drive end of the electric push rod 11 through a flange to ensure efficient power transmission; the bottom surface of the spreading pressure plate 8 is parallel to the top surface of the spreading cavity 5, and its size is slightly smaller than the inner diameter of the spreading cavity 5 to avoid interference with the inner wall of the spreading frame 4 during movement; the buffer component is located between the spreading pressure plate 8 and the drive plate 7, which is used to convert the rigid driving force of the electric push rod 11 into flexible pressure to prevent the filling material from clumping due to excessive instantaneous pressure.

[0020] In some technical solutions, the buffer assembly includes a buffer body 13 installed at the bottom of the drive plate 7. A buffer spring 15 is installed inside the buffer body 13. A buffer plate 14 is installed at the end of the buffer spring 15. An I-shaped groove 18 is opened at the bottom of the buffer plate 14. An I-shaped slider 19 is installed at the top of the spreading pressure plate 8. The I-shaped slider 19 is installed in the I-shaped groove 18.

[0021] In the specific implementation process, the buffer body 13 is a rectangular cavity structure with an open bottom, and its hollow internal area provides expansion and contraction space for the buffer spring 15. The buffer spring 15 is a cylindrical helical compression spring, and different stiffness coefficients can be designed according to the fluffiness of the summer quilt filling material. When the drive plate 7 moves down, the buffer spring 15 is compressed and generates elastic force to achieve pressure buffering. The bottom end of the buffer plate 14 is welded to the bottom end of the buffer spring 15, and the I-shaped groove 18 on its bottom surface is clearance-fitted with the I-shaped slider 19 at the top of the spreading pressure plate 8. The design of the I-shaped structure can withstand the pressure in the vertical direction and the shear force in the horizontal direction, preventing the spreading pressure plate 8 from separating from the buffer plate 14 and improving the reliability of the connection.

[0022] In some technical solutions, mounting screw holes are provided on both inner walls of the I-shaped slide 18, and mounting screw grooves are provided on both outer walls of the I-shaped slider 19. The mounting screw holes and mounting screw grooves are screwed with bolt bodies 20.

[0023] In practical implementation, the mounting screw holes on both sides of the I-shaped slide 18 and the mounting screw grooves on both sides of the I-shaped slider 19 are coaxially designed, ensuring that the bolt body 20 can simultaneously screw and fix both. After the spreading pressure plate 8 is inserted into the I-shaped slide 18 through the I-shaped slider 19, tightening the bolt body 20 can eliminate the fit gap between the slider and the slide, rigidly locking the spreading pressure plate 8 and the buffer plate 14 to prevent relative displacement due to vibration during spreading; at the same time, this structure facilitates the disassembly and replacement of the spreading pressure plate 8, improving the versatility of the device.

[0024] In some technical solutions, a circular groove 201 is provided at the bottom end of the bolt body 20, and a bolt rod 203 is installed at the bottom end of the circular groove 201. The bolt rod 203 is screwed into the mounting screw hole and mounting screw groove. A retaining ring 206 is installed at the upper outer end of the bolt rod 203. An annular pressure plate 205, a spring 207 and an annular rubber sheet 202 are fitted on the circumferential surface of the bolt rod 203. An extrusion block 204 is installed at the upper edge of the annular rubber sheet 202.

[0025] In the specific implementation process, the diameter of the circular groove 201 is slightly larger than the working end size of the screwdriver or wrench, making it easier for the tool to reach in and tighten the bolt body 20; the thread precision of the bolt shank 203 is 6g, ensuring a tight fit with the mounting screw hole and screw groove. The retaining ring 206 is welded and fixed to the bolt shank 203, used to limit the axial position of the annular pressure plate 205 and the spring 207; the spring 207 is in a pre-compressed state, and its elastic force is transmitted to the annular rubber sheet 202 through the annular pressure plate 205, so that the annular rubber sheet 202 fits tightly against the outer wall of the I-shaped slide groove 18, and the anti-loosening effect is achieved by using the friction of the rubber. The annular rubber sheet 202 is made of nitrile rubber, and the extrusion block 204 is a protruding structure on the upper edge of the annular rubber sheet 202. When the bolt body 20 is vibrated and tends to loosen, the extrusion block 204 contacts the retaining ring 206 to generate a reverse friction force, further enhancing the anti-loosening performance.

[0026] In some technical solutions, balance cavities 16 are provided on both sides of the top of the buffer body 13, and balance rods 17 are installed on both sides of the buffer plate 14, with the balance rods 17 inserted into the balance cavities 16.

[0027] In the specific implementation process, the balancing cavity 16 is a cylindrical hole opened on both sides of the top of the buffer body 13, and its axis is parallel to the extension and contraction direction of the buffer spring 15; the balancing rod 17 is a round rod welded to both sides of the buffer plate 14, which can slide along the axial direction of the balancing cavity 16. When the buffer spring 15 extends and contracts, causing the buffer plate 14 to move, the balancing rod 17 slides synchronously in the balancing cavity 16, limiting the radial displacement of the buffer plate 14, ensuring that the buffering force is evenly distributed along the width direction of the spreading pressure plate 8, and avoiding uneven local pressure on the filler material due to the tilt of the buffer plate 14.

[0028] In some technical solutions, the top of the spreading frame 2 is provided with sliding holes 6 at the four corners of the electric push rod 11, and a sliding cylinder 9 is installed inside the sliding hole 6. The top of the drive plate 7 is provided with sliding rods 10 at the four corners, and the sliding rods 10 are installed inside the sliding cylinder 9.

[0029] In the specific implementation process, the sliding hole 6 is a round hole that penetrates the spreading frame 2. It is embedded in the sliding hole 6 by interference fit. The sliding rod 10 is a round rod welded to the four corners of the top of the drive plate 7. Its diameter is clearance fit with the inner diameter of the sliding cylinder 9.

[0030] In some technical solutions, a protective pad 12 is installed at the bottom of the spreading plate 8.

[0031] In the specific implementation process, the protective pad 12 is made of flexible material.

[0032] Working Principle: The summer quilt blank to be filled is placed into the spreading cavity of the summer quilt spreading frame. The electric push rod is activated, driving the drive plate connected to the lower end to descend vertically along the slide rod-slide cylinder guide structure at the four corners of the spreading frame, causing the spreading pressure plate to move down synchronously. During the descent, the buffer spring of the buffer component is compressed, generating elastic force, which converts the rigid driving force into gentle pressure. The balance rod slides in the balance cavity to prevent the buffer plate from shifting, ensuring that the pressure is evenly applied to the spreading pressure plate. The spreading pressure plate is stably connected to the buffer plate through the I-shaped slider, and the bottom protective padding layer contacts the summer quilt. Under the action of pressure, the filling material is evenly spread in the spreading cavity. After completion, the electric push rod drives the mechanism to reset.
