Description

Technical Field

[0001] The present invention relates to the technical field of compression equipment, and in particular to a compressor and a compression method. Background Art

[0002] For some flexible items, such as mattresses, pillows, etc., these items are generally filled with memory foam or latex materials. In order to make these items more convenient to transport, these items are generally compressed by a compressor to reduce their volume before transportation.

[0003] Existing compressors for bedding generally include a compression platform and a pressure head assembly located above the compression platform, and the pressure head assembly includes a pressing plate and a driver that drives the pressing plate to move toward the compression platform. The compression process of this type of compressor is as follows: first place the items to be compressed on the compression platform, then start the driver, the driver drives the pressing plate to move toward the compression platform, and when the pressing plate moves to the set position, it stops, completing the compression process of the items. After the compression is completed, the items can be plastic-sealed and fixed by other packaging components.

[0004] After the compressors currently on the market compress the products, since the compression direction is from top to bottom in the height direction, the compressed products will extend in the horizontal direction, that is, the width of the compressed products will be greater than the width of the products before compression. This will cause difficulties in subsequent packaging and inconvenience in use. For some compressed items, the internal fillings will extend in the horizontal direction, thereby expanding the outer cover of the items. If the compression is not released for a long time, the items will be damaged. Summary of the invention

[0023] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, device, product or server that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or servers.

[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The present invention discloses a specific implementation of a compressor, see Figure 1 The compressor includes a pressing plate 1, a driver (not shown) for driving the pressing plate 1 to move downward, a conveyor belt (not shown) located directly below the pressing plate 1 and used to convey the objects to be compressed, and a plastic sealing mechanism (not shown). It should be noted that the conveyor belt and the plastic sealing mechanism are both conventional conveyor belts and plastic sealing mechanisms. The conveyor belt acts as a compression platform and cooperates with the pressing plate 1 to compress the objects to be compressed. The conveyor belt can transfer the objects to be compressed and the compressed objects. The plastic sealing mechanism acts as a packaging mechanism, which can be a film-coated heat seal or a bag-type solid seal, and is mainly used to plastic seal the compressed objects to prevent the compressed objects from rebounding.

[0027] As an improvement, see Figures 1 to 3 The pressing plate 1 is provided with a side stop mechanism, which includes two side stop members 2. Each side stop member 2 is arranged along the circumference of the object to be compressed so that each side stop member 2 together forms a cavity for accommodating the object to be compressed.

[0028] Optionally, there are two side blocks 2, which are arranged opposite to each other and are arranged on the left and right sides of the bottom surface of the pressing plate 1. In other embodiments, the two side blocks 2 can also be arranged on the front and rear sides of the bottom surface of the pressing plate 1. In this embodiment, each side block 2 is a rectangular strip, and the side block 2 itself is elastic and can be compressed. Specifically, it can be made of elastic materials such as latex, rubber, silicone, memory foam, etc.

[0029] In order to make the side stop mechanism suitable for objects of various specifications, each side stop member 2 can move relative to the pressing plate 1. Figure 2 and Figure 3The side block mechanism also includes a driving motor 31, a screw body 35, a screw nut 36, a synchronous belt 34, a driving wheel 32, a driven wheel 33, a slide rail 37 and a slide seat 38. The driving motor 31 is fixedly mounted on the top of the pressure plate 1, the slide rail 37 is fixedly mounted on the top side of the pressure plate 1, and the slide seat 38 is slidably mounted on the slide rail 37. The slide seat 38 and the slide rail 37 are both conventional guide rail components on the market. The screw body 35 is rotatably mounted on the top of the pressure plate 1 through the bearing mounting seat 4. Specifically, the bearing mounting seat 4 can be fixedly mounted on the top or side of the pressure plate 1. The bearing body is fixedly mounted in the bearing mounting seat 4. The screw body 35 is inserted into the bearing body, and the screw body 35 is relatively fixed to the inner ring of the bearing body. The outer ring of the bearing body is fixed relative to the bearing mounting seat 4 and the pressure plate 1, so that the screw body 35 can be rotated relative to the pressure plate 1. The screw nut 36 is sleeved on the outer peripheral side of the screw body 35, and the screw nut 36 is meshed with the screw body 35. The rotation of the screw body 35 will drive the screw nut 36 to slide along the axial direction of the screw body 35. In addition, the screw nut 36 is fixedly connected to the slide seat 38. The screw nut 36 can be directly fixedly connected to the slide seat 38, or the screw nut 36 can be fixedly connected to the slide seat 38 through other connecting parts. The driving wheel 32 is transmission-connected to the output shaft of the driving motor 31. The output shaft of the driving motor 31 can be transmission-connected to the driving wheel 32 through a gear set and a transmission shaft. It can be understood that the driving motor 31 can drive the driving wheel 32 to rotate. The driven wheel 33 is fixedly sleeved on the end of the screw body 35, and the synchronous belt 34 is sleeved on the outer peripheral side of the driving wheel 32 and the driven wheel 33. Combined with Figure 2 The pressure plate 1 is provided with a long hole 11, and a connecting rod 39 that can slide along the long hole 11 is passed through the long hole 11. The connecting rod 39 is placed parallel to the axial direction of the long hole 11. The top end of the connecting rod 39 is fixedly connected to the sliding seat 38, and the bottom end of the connecting rod 39 is fixedly connected to the side stopper 2. The number of the connecting rod 39 can be one or more than two, and can be selectively set according to actual needs.

[0030] The working process of the side stop mechanism is that the driving motor 31 is started and drives the driving wheel 32 to rotate. The driving wheel 32 rotates and drives the driven wheel 33 to rotate through the synchronous belt 34. Since the driven wheel 33 is fixedly connected to the screw body 35, the rotation of the driven wheel 33 will drive the screw body 35 to rotate. The rotation of the screw body 35 drives the screw nut 36 to slide along the axial direction of the screw body 35. Since the screw nut 36 is fixedly connected to the sliding seat 38, the connecting rod 39 and the side stop 2 in sequence, the side stop 2 will be driven to slide in the horizontal direction during the axial sliding of the screw body 35, thereby realizing the horizontal sliding of the side stop 2 relative to the pressure plate 1, and the distance between the side stops 2 can be adjusted, thereby improving the applicability of the compressor and being able to meet the compression work requirements of various items.

[0031] The compressor of this embodiment is provided with a side stop mechanism. The side stop 2 can prevent the object from extending in the horizontal direction during the compression process, thereby ensuring that the width of the object is consistent before and after compression, solving the problem of increased width of the object after compression in the past, providing convenience for subsequent packaging and transportation, avoiding the problem of the internal filler of the object expanding the outer cover of the object, and ensuring the compression quality.

[0032] In other embodiments, the number of side blocks 2 can be four, and the four side blocks 2 are arranged on the front side, the rear side, the left side and the right side of the bottom surface of the pressing plate 1. The four side blocks 2 together form a rectangular cavity, which can ensure that the length and width of the compressed object do not change. In addition, the side blocks 2 can also be arranged in an L shape, and the two side blocks 2 are symmetrically installed at the bottom of the pressing plate 1 with the center being mutually centered. The two side blocks 2 can move toward or away from each other along the diagonal line of the pressing plate 1, which can also play the role of side block anti-extension.

[0033] In other embodiments, a side stopper driver is provided above or to the side of the pressing plate 1, and the side stopper driver is provided with a telescopic rod that can telescope in the horizontal direction and is located at the bottom of the pressing plate 1, and the end of the telescopic rod is fixedly connected to the side stopper 2 through a connector. For example, a cylinder, an oil cylinder or a linear guide is provided on the top of the pressing plate 1, and the working end of the cylinder, the working end of the oil cylinder or the working end of the linear guide is fixedly connected to the side stopper 2 through a heterosexual connector (L-shaped, U-shaped), which can also realize the movement of the side stopper 2 relative to the pressing plate 1.

[0034] A specific implementation of a compression method of this embodiment includes the following steps: Step a, moving the object to be compressed to the bottom of the pressing plate 1, driving the two side blocks 2 to move backwards, so that the distance between the two side blocks 2 is greater than the width of the object to be compressed.

[0035] Step b, driving the pressing plate 1 to move downward, and the pressing plate 1 stops moving downward after contacting the object to be compressed.

[0036] Step c: driving the two side blocks 2 to move toward each other so that the distance between the two side blocks 2 is equal to or smaller than the width of the object to be compressed.

[0037] Step d, driving the pressing plate 1 to continue to move downward for compression, and stopping the downward movement of the pressing plate 1 after the compressed object is completely compressed.

[0038] Step e, driving the two side blocks 2 to move backwards to separate the two side blocks 2 from the compressed objects, and finally driving the pressing plate 1 to move upwards to complete a compression process.

[0039] The compression method of this embodiment can ensure that the width of the article before and after compression remains consistent by reasonably designing the compression process, and can also prevent the side stopper 2 from clamping the compressed article and moving it upward during the return process of the equipment, thereby ensuring the smoothness of the subsequent article conveying process and effectively improving the work efficiency of compression packaging.

[0040] Finally, it should be noted that the compressor disclosed in the embodiment of the present invention is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, it should be understood by those skilled in the art that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
