Description

Technical Field

[0001] The utility model relates to the field of cotton-filling integrated machines, in particular to a cotton-filling integrated machine for sofa production. Background Art

[0002] A sofa is a piece of furniture that typically features a soft seat and backrest for sitting or relaxing. Sofas are made from a variety of materials, with fabric and leather being common. Sofas come in a variety of styles, including single-seater sofas, double-seater sofas, multi-seater sofas (such as long sofas), and modular sofas. They also come in a variety of designs, including modern minimalist, European classical, and Chinese styles, to suit different home decor needs. To ensure the comfort of a sofa, a cotton padded lining is typically installed on the sofa's inner layer to increase its softness and enhance its performance. However, the existing cotton padded lining is typically manually filled, resulting in low efficiency. Therefore, a new all-in-one cotton filling machine is needed to improve the efficiency of cotton padded filling.

[0003] An existing cotton-filling machine for sofa production places cotton material in the cotton-filling machine for processing, then discharges the cotton material through a cotton guide tube to a cotton guide nozzle provided at one end of the cotton guide tube, and discharges the cotton material into an empty cotton bale through the cotton guide nozzle, thereby achieving a quick cotton-filling effect.

[0004] However, for the existing cotton filling machines for sofa production, since the cotton bales required for sofas are usually large, the cotton material discharged through the cotton guide nozzle is usually discharged to the center of the cotton material, and the edges and corners of the cotton bales cannot be filled, resulting in uneven cotton material discharge, reducing the comfort of sofa use, and the actual device cannot achieve the desired effect. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a cotton-filling integrated machine for sofa production, so as to solve the technical problem that the existing cotton-filling integrated machine for sofa production has poor performance.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a cotton-filling integrated machine for sofa production, comprising a filling machine, a cotton feeding pipe being provided on one side of the filling machine, the cotton feeding pipe being fixedly mounted on a mounting platform, a cotton feeding nozzle being provided at one end of the cotton feeding pipe, a cotton dividing plate being provided in the cotton feeding nozzle, a first mounting base being provided at one end of the cotton dividing plate, a second mounting base being provided at the other end of the cotton dividing plate, a side panel being movably mounted between the first mounting base and the second mounting base, a fixed block being provided at one end of the side panel, a limiting groove being provided on the top of the first mounting base, a limiting block being fixedly mounted on the top of the first mounting base, an inner cavity being provided in the second mounting base, a spring being provided on one side of the inner cavity, one end of the spring being connected to the sliding plate, and a movable sleeve being provided in the sliding plate.

[0007] By adopting the above technical solution, the problem of poor use effect of the existing cotton-filling integrated machine for sofa production is solved. A cotton-dividing plate is provided, one end of the cotton-dividing plate is provided with a first mounting base, and the other end is provided with a second mounting base.

[0015] Preferably, by setting the cross-section of the limiting groove to a fan-shaped surface and the fixing block being sleeved in the limiting groove, a limiting effect can be exerted on the side panel to prevent the side panel from rotating automatically. A circular groove is provided in the limiting block, and a limiting rod provided on one side of the side panel is sleeved in the limiting block, so that the side panel can be movably installed between the first mounting base and the second mounting base.

[0016] The utility model is further configured such that another set of limiting rods is provided at one end of the side plate away from the fixed block, and the limiting rods are sleeved in a movable sleeve fixedly installed on one side of the sliding plate.

[0017] Preferably, another set of limit rods is provided at one end of the side panel away from the fixed block, and the limit rods are sleeved in a movable sleeve fixedly installed on one side of the sliding plate, so that the limit rods can slide upward by squeezing the spring, thereby enabling the side panel to achieve the effect of adjusting the angle.

[0018] The present invention is further configured such that the length of the limiting rod is greater than the thickness of the sliding plate and the inner cavity, and the side plate is not in contact with the first mounting base and the second mounting base.

[0019] Preferably, by setting the length of the limit rod to be greater than the thickness of the sliding plate and the inner cavity, the side plate does not contact the first mounting base and the second mounting base, so that the side plate will not collide with the inner wall of the cotton feed nozzle when sliding upward, thereby affecting the use effect of the side plate.

[0020] The utility model is further configured such that the surface of the side plate is smooth, and one side of the side plate is passivated.

[0021] Preferably, by setting the surface of the side panel to be smooth and passivating one side of the side panel, it is possible to prevent cotton material from hanging on the side panel, thereby affecting the normal use of the side panel.

[0022] The utility model is further configured such that the first mounting base and the second mounting base are connected to the back surface of the cotton separating plate and are smoothed.

[0023] Preferably, by interconnecting the first mounting base and the second mounting base with the back of the cotton separating plate and smoothing them, the volume of the first mounting base and the second mounting base and the cotton separating plate can be reduced, avoiding excessive contact between the first mounting base and the second mounting base and the cotton separating plate and the cotton material, thereby causing blockage of the cotton material.

[0024] The utility model is further configured such that the thickness of the side panels is smaller than the thickness of the cotton separating panels, and the cotton separating panels are not in direct contact with the side panels.

[0025] Preferably, by setting the thickness of the side panel to be smaller than the thickness of the cotton separating panel, and the cotton separating panel is not in direct contact with the side panel, the cotton material can smoothly pass through the cotton separating panel to one side of the side panel, and there will be no blockage of the cotton material, so that the device can operate smoothly.

When it is necessary to pass the cotton feeding nozzle, When filling the cotton bale, you need to hold the side of the side panel and slide it upwards. The limiting rod installed in the movable sleeve at one end of the side panel will push the sliding plate to make the sliding plate slide to one side of the inner cavity, so that the fixed block is taken out of the limiting groove, and then the angle of the side panel is adjusted according to the size of the cotton bale. The fixing block is installed in another set of limiting grooves to limit the side panel again. The filling machine is started to allow the cotton material to be discharged from the cotton feed nozzle. Since the cotton feed nozzle is provided with a cotton dividing plate and an inclined side panel, part of the cotton material can be filled to the side of the cotton bale, so that the cotton material can be arranged more evenly in the cotton bale, which can achieve better use effect.
