Description

Technical Field

[0001] The utility model relates to the technical field of gravity quilt manufacturing, in particular to a crystal sand paving structure. Background Art

[0002] A gravity quilt is a type of quilt that is filled with additional weight-added fillers to affect human sleep by increasing the mass of the quilt. Its specific structure is as follows: a weight-added filler and a quilt body; the weight-added filler is a granular filler; a plurality of weight-added fillers are provided and filled in the quilt body.

[0003] The specification states that the quilt body is evenly divided into a plurality of small cells; each of the small cells is filled with the weight-increasing filler; the small cells are square in shape, and the side length is 15 cm to 20 cm.

[0004] In order to replace manual spreading during mass production, the applicant has designed a gravity quilt spreading device, application number 2024205726220, which includes a slide rail and a spreading device, the spreading device is arranged on the slide rail, a spreading trough is provided on the spreading device, and a spreading hole is provided at the bottom of the spreading trough that passes through from top to bottom. The design adopts a spreading trough with uniform spreading holes, so that it moves above the quilt core through the slide rail during spreading and spreads the crystal sand on the quilt core.

[0005] In actual use, it is found that the amount of material at each paving point depends on the length of time its paving hole is open, and the time the paving hole is open depends on the moving speed of the paving device on the slide rail. When less material needs to be laid at a paving point, the paving device needs to move faster, and the fall of the material will be affected. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to:

[0007] 1. Design a paving bracket for laying gravity fillers in a gravity blanket so that the material laying amount at each paving point can be controlled without adjusting the moving speed of the paving bracket.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crystal sand paving structure, comprising a material storage trough, a discharging rod, a discharging baffle, a material paving bracket and a slide rail, the material paving bracket slides on the slide rail, the material storage trough is fixedly mounted on the material paving bracket, the first discharging port is arranged at the lower part of the material storage trough, the discharging rod is provided with a plurality of discharging holes which pass through from top to bottom, the upper end of the discharging hole corresponds to the position of the first discharging port, the material storage baffle is arranged near the upper end of the discharging hole, the shape of the material storage baffle corresponds to the shape of the first discharging port, the lower end of the discharging hole corresponds to the shape of the discharging baffle, the discharging rod is rotatably connected to the material paving bracket through a first swing rod, the first swing rod is connected to the second swing rod, the first swing rod and the second swing rod move synchronously, and a detachable adjustment strip is arranged on the slide rail, and a plurality of protrusions are arranged on the adjustment strip, and the protrusions correspond to the far end position of the second swing rod.

[0009] When in use, first pour crystal sand into the storage tank as the material to be laid. After the crystal sand enters the storage tank, it enters the discharge hole from the first discharge port at the bottom of the storage tank. At this time, the lower end of the discharge hole is blocked by the discharge baffle, so that the material cannot fall from the lower end of the discharge hole.

[0010] When the material paving operation starts, the material paving bracket slides on the slide rail, which can be driven by a uniform motor or a non-uniform manual drive. The far end of the second swing rod hits the protrusion on the adjustment bar and then rotates relative to the material paving bracket. The first swing rod rotates synchronously and drives the discharge rod to move. At this time, the material storage baffle on the discharge rod gradually covers the first discharge port until it is completely blocked, and the lower end of the discharge hole on the discharge rod gradually gets rid of the blockage of the discharge baffle, and the material inside falls to pave the material.

[0011] After the far end of the second swing rod rotates to the maximum angle and passes the position of the protrusion, the discharging rod, the first swing rod, and the second swing rod are affected by gravity and return to the original position synchronously. The material storage baffle on the discharging rod gradually leaves the first discharging port until the first discharging port is connected with the upper end of the discharging hole, and the material can continue to enter the discharging hole. The lower end of the discharging hole is gradually covered and blocked by the discharging baffle, so that the material cannot fall from the lower end of the discharging hole.

[0012] The discharge rod in this scheme should be replaceable according to the use requirements. In this scheme, the controlling factor affecting the material quantity at each paving point is the capacity of the discharge hole. The staff can adjust the capacity of the discharge hole to make the material quantity at each paving point meet the design requirements.

[0013] Optionally, there are two first swing rods, and the two first swing rods are respectively connected to two ends of the discharging rod.

[0014] Optionally, the second swing rod corresponds one-to-one to the first swing rod.

[0015] Optionally, a swinging space for the movement of the first swinging rod is provided between the material storage trough and the material laying bracket, and a connection point between the material storage trough and the material laying bracket is arranged outside the swinging space.

[0016] Optionally, the plurality of discharge holes are equidistantly arranged on the discharge rod.

[0017] Optionally, the size of the first discharge port is smaller than the size of the upper end of the discharge hole.

[0018] The utility model has the beneficial technical effect that: through the design of the paving structure, the capacity of the discharge hole becomes the actual paving material amount affecting each paving point. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] Reference Figure 1-4As shown, a crystal sand 10 paving structure comprises a storage trough 1, a discharging rod 2, a discharging baffle 3, a paving bracket 4 and a slide rail 5. The paving bracket 4 slides on the slide rail 5. The storage trough 1 is fixedly mounted on the paving bracket 4. A first discharging port 6 is arranged at the lower part of the storage trough 1. A plurality of discharging holes 7 which pass through from top to bottom are arranged on the discharging rod 2. The upper end of the discharging hole 7 corresponds to the position of the first discharging port 6. A storage baffle is arranged near the upper end of the discharging hole 7 of the discharging rod 2. The shape of the storage baffle corresponds to the shape of the first discharging port 6. The lower end of the discharging hole 7 corresponds to the shape of the discharging baffle 3. The discharging rod 2 is rotatably connected to the paving bracket 4 through a first swing rod 8. The first swing rod 8 is connected to the second swing rod 9. The first swing rod 8 moves synchronously with the second swing rod 9. A detachable adjustment strip is arranged on the slide rail 5. A plurality of protrusions 11 are arranged on the adjustment strip. The protrusions 11 correspond to the far end positions of the second swing rod 9.

[0026] There are two first swinging rods 8, and the two first swinging rods 8 are respectively connected to the two ends of the discharging rod 2. The second swinging rod 9 corresponds to the first swinging rod 8 one by one.

[0027] A swinging space for the first swinging rod 8 is provided between the material storage tank 1 and the material spreading support 4, and the connection point between the material storage tank 1 and the material spreading support 4 is arranged outside the swinging space. A plurality of discharge holes 7 are arranged equidistantly on the discharge rod 2. The size of the first discharge port 6 is smaller than the size of the upper end of the discharge hole 7.

[0028] When in use, first pour crystal sand 10 into the storage tank 1 as the material to be laid. After the crystal sand 10 enters the storage tank 1, it enters the discharge hole 7 from the first discharge port 6 at the lower part of the storage tank 1. At this time, the lower end of the discharge hole 7 is blocked by the discharge baffle 3, so that the material cannot fall from the lower end of the discharge hole 7.

[0029] When the material laying operation starts, the material laying bracket 4 slides on the slide rail 5, which can be driven by a uniform motor or a non-uniform manual drive. The far end of the second swing rod 9 hits the protrusion 11 on the adjustment bar and rotates relative to the material laying bracket 4. The first swing rod 8 rotates synchronously in the swing space and drives the discharge rod 2 to move. At this time, the material storage baffle on the discharge rod 2 gradually covers the first discharge port 6 until it is completely blocked, and the lower end of the discharge hole 7 on the discharge rod 2 gradually gets rid of the blockage of the discharge baffle 3, and the material inside it falls to lay the material.

[0030] After the far end of the second swing rod 9 rotates to the maximum angle, it passes over the position of the protrusion 11. At this time, the discharge rod 2, the first swing rod 8, and the second swing rod 9 are affected by gravity and return to the original position. The storage baffle on the discharge rod 2 gradually leaves the first discharge port 6 until the first discharge port 6 is connected with the upper end of the discharge hole 7, and the material can continue to enter the discharge hole 7. The lower end of the discharge hole 7 is gradually covered and blocked by the discharge baffle 3, so that the material cannot fall from the lower end of the discharge hole 7.

[0031] The discharge rod 2 in this solution should be replaceable according to the use requirements. In this solution, the controlling factor affecting the amount of material at each paving point is the capacity of the discharge hole 7. The staff can adjust the capacity of the discharge hole 7 to make the amount of material at each paving point meet the design requirements.
