Description

Technical Field

[0001] This utility model relates to the field of compression equipment technology, and in particular to a compressor. Background Technology

[0002] For some flexible items, such as mattresses and pillows, the interior is usually filled with memory foam or latex. To make these items easier to transport, they are usually compressed by a compressor to reduce their volume before transport.

[0003] Existing compressors for bedding typically include a compression platform and a pressure head assembly located above the compression platform. The pressure head assembly includes a pressure plate and a driver that moves the pressure plate toward the compression platform. The compression process of this type of compressor is as follows: first, the item to be compressed is placed on the compression platform; then, the driver is activated, causing the pressure plate to move toward the compression platform. When the pressure plate reaches a set position, it stops, completing the compression process. After compression, the item can be sealed and secured using other packaging components.

[0004] Currently, compressors on the market compress products vertically from top to bottom, causing the compressed product to expand horizontally. This means the width of the compressed product is greater than the width before compression, which makes subsequent packaging difficult and inconvenient to use. In some cases, the internal filling material of the compressed item will expand horizontally, stretching the outer casing. If the compression is not released for a long time, it will damage the item. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a compressor that solves the problem of increased width after compression of items by adding a side baffle mechanism.

[0006] To solve the above-mentioned technical problems, this utility model discloses a compressor, including a pressure plate and a driver that drives the pressure plate to move downward. The pressure plate is provided with a side blocking mechanism, which includes at least two side blocking members. Each side blocking member is arranged along the circumference of the item to be compressed so that the side blocking members together form a cavity for accommodating the item to be compressed. Each side blocking member can move relative to the pressure plate.

[0007] There are two side stops, which are arranged opposite each other on the left and right sides of the bottom surface of the pressure plate.

[0008] The side guard is rectangular in shape.

[0009] The number of side stops is four, which are located on the front, rear, left and right sides of the bottom surface of the pressure plate.

[0010] The side guard is L-shaped.

[0011] The side stop mechanism includes a drive motor, a lead screw body, a lead screw nut, a timing belt, a drive pulley, a driven pulley, a slide rail, and a slide block. The drive motor is fixedly mounted on the top of the pressure plate, the slide rail is fixedly mounted on the top of the pressure plate, and the slide block is slidably mounted on the slide rail. The lead screw body is rotatably mounted on the top of the pressure plate via a bearing mounting seat. The lead screw nut is sleeved on the outer periphery of the lead screw body and is fixedly connected to the slide block. The drive pulley is connected to the output shaft of the drive motor. The driven pulley is fixedly sleeved on the end of the lead screw body. The timing belt is sleeved on the outer periphery of the drive pulley and the driven pulley. The pressure plate has an elongated hole, and a connecting rod that can slide along the elongated hole passes through the hole. The top end of the connecting rod is fixedly connected to the slide block, and the bottom end of the connecting rod is fixedly connected to the side stop.

[0012] The pressure plate is provided with a side stop actuator above or to the side. The side stop actuator is provided with a telescopic rod that can move horizontally and is located at the bottom of the pressure plate. The end of the telescopic rod is fixed to the side stop through a connector.

[0013] This also includes a conveyor belt, which is located directly below the pressure plate.

[0014] This also includes a sealing mechanism for sealing compressed items.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By setting a side baffle mechanism, the compressor can prevent the item from extending in the horizontal direction during the compression process, ensuring that the width of the item is consistent before and after compression. This solves the problem of the item's width increasing after compression, provides convenience for subsequent packaging and transportation, avoids the problem of the internal filling material expanding the outer cover of the item, and ensures the compression quality.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, 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 not listed, or may optionally include other steps or units inherent to these processes, methods, products, or servers.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model discloses a specific embodiment of a compressor, please see... Figure 1 The compressor includes a pressure plate 1, a driver (not shown) that drives the pressure plate 1 downward, a conveyor belt (not shown) located directly below the pressure plate 1 for conveying the items to be compressed, and a sealing mechanism (not shown). It should be noted that the conveyor belt and sealing mechanism are conventional conveyor belts and sealing mechanisms. The conveyor belt, as a compression platform, works with the pressure plate 1 to compress the items to be compressed. The conveyor belt can transfer the items to be compressed and the compressed items. The sealing mechanism, as a sealing mechanism, can be a film-type heat seal or a bag-type solid seal, mainly used to seal the compressed items to prevent them from springing back.

[0024] As an improvement, please see Figures 1 to 3 The pressure plate 1 is provided with a side blocking mechanism, which includes two side blocking parts 2. Each side blocking part 2 is arranged along the circumference of the item to be compressed, so that each side blocking part 2 together forms a cavity for accommodating the item to be compressed.

[0025] Optionally, there are two side stops 2, which are arranged opposite each other on the left and right sides of the bottom surface of the pressure plate 1. In other embodiments, the two side stops 2 can also be arranged on the front and rear sides of the bottom surface of the pressure plate 1. In this embodiment, each side stop 2 is a rectangular strip. The side stops 2 are elastic and compressible, and can be made of elastic materials such as latex, rubber, silicone, or memory foam.

[0026] To enable the side guard mechanism to be adapted to various sizes of items, each side guard 2 can move relative to the pressure plate 1. Figure 2 and Figure 3 The side-blocking mechanism also includes a drive motor 31, a lead screw body 35, a lead screw nut 36, a timing belt 34, a driving pulley 32, a driven pulley 33, a slide rail 37, and a slide block 38. The drive 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 block 38 is slidably mounted on the slide rail 37. Both the slide block 38 and the slide rail 37 are conventional guide rail assemblies available on the market. The lead screw body 35 is rotatably mounted on the top of the pressure plate 1 via a bearing mounting seat 4. Specifically, the bearing mounting seat 4 can be fixedly mounted on the top or side of the pressure plate 1. A bearing body is fixedly installed inside the bearing mounting seat 4, and the lead screw body 35 passes through the bearing body. The inner ring of the lead screw body 35 is fixed relative to the inner ring of the bearing body, and the outer ring of the bearing body is fixed relative to the bearing mounting seat 4 and the pressure plate 1, thus enabling the lead screw body 35 to rotate relative to the pressure plate 1. A lead screw nut 36 is sleeved on the outer periphery of the lead screw body 35. The lead screw nut 36 is engaged with the lead screw body 35, and rotation of the lead screw body 35 will cause the lead screw nut 36 to slide along the axial direction of the lead screw body 35. Additionally, the lead screw nut 36 is fixedly connected to the slide block 38. The lead screw nut 36 can be directly fixed to the slide block 38, or it can be fixed to the slide block 38 through other connecting parts. The driving wheel 32 is driven by the output shaft of the drive motor 31. The output shaft of the drive motor 31 can be driven by the driving wheel 32 through a gear set and a transmission shaft. This means that the drive motor 31 can drive the driving wheel 32 to rotate synchronously. The driven wheel 33 is fixedly sleeved on the end of the lead screw body 35, and the synchronous belt 34 is sleeved on the outer periphery of the driving wheel 32 and the driven wheel 33. Figure 2 The pressure plate 1 has an elongated hole 11, and a connecting rod 39 that can slide along the elongated hole 11 is inserted inside the elongated hole 11. The connecting rod 39 is placed parallel to the axis of the elongated hole 11. The top end of the connecting rod 39 is fixedly connected to the slide block 38, and the bottom end of the connecting rod 39 is fixedly connected to the side stop 2. The number of connecting rods 39 can be one or more, and can be selectively set according to actual needs.

[0027] The working process of the side stop mechanism is as follows: the drive motor 31 starts and drives the drive wheel 32 to rotate. The rotation of the drive wheel 32 drives the driven wheel 33 to rotate through the synchronous belt 34. Since the driven wheel 33 is fixedly connected to the lead screw body 35, the rotation of the driven wheel 33 will drive the lead screw body 35 to rotate. The rotation of the lead screw body 35 will drive the lead screw nut 36 to slide along the axial direction of the lead screw body 35. Since the lead screw nut 36 is fixedly connected to the slide block 38, the connecting rod 39 and the side stop 2 in sequence, the sliding of the lead screw nut 36 along the axial direction of the lead screw body 35 will drive the side stop 2 to slide in the horizontal direction. This allows the side stop 2 to slide relative to the pressure plate 1 in the horizontal direction, thereby adjusting the distance between the side stops 2, improving the applicability of the compressor and meeting the compression needs of various items.

[0028] The compressor in this embodiment uses a side baffle mechanism. The side baffle 2 can prevent the item from expanding horizontally during compression, ensuring that the width of the item is consistent before and after compression. This solves the problem of the item's width increasing after compression, providing convenience for subsequent packaging and transportation. It also avoids the problem of the internal filler expanding the outer cover of the item, ensuring the compression quality.

[0029] In other embodiments, the number of side stops 2 can be four. The four side stops 2 are located on the front, rear, left, and right sides of the bottom surface of the pressure plate 1, forming a rectangular cavity that ensures the length and width of the compressed item remain unchanged. Alternatively, the side stops 2 can be L-shaped, with two side stops 2 symmetrically mounted on the bottom of the pressure plate 1. The two side stops 2 can move towards or away from each other along the diagonal of the pressure plate 1, similarly serving to prevent stretching.

[0030] In other embodiments, a side stop actuator is provided above or to the side of the pressure plate 1. The side stop actuator has a telescopic rod that can extend and retract in the horizontal direction and is located at the bottom of the pressure plate 1. The end of the telescopic rod is fixedly connected to the side stop 2 through a connector. For example, a cylinder, hydraulic cylinder, or linear guide is provided on the top of the pressure plate 1. The working end of the cylinder, the working end of the hydraulic cylinder, or the working end of the linear guide is fixedly connected to the side stop 2 through a non-standard connector (L-shaped, U-shaped), which can also realize the movement of the side stop 2 relative to the pressure plate 1.

[0031] The compression method of the compressor in this embodiment includes the following steps: Step a, the item to be compressed is moved to the bottom of the pressure plate 1, and the two side baffles 2 are driven to move in opposite directions so that the distance between the two side baffles 2 is greater than the width of the item to be compressed.

[0032] Step b: Drive the pressure plate 1 downwards, and stop moving downwards after the pressure plate 1 contacts the item to be compressed.

[0033] Step c: Drive the two side stops 2 to move towards each other, so that the distance between the two side stops 2 is equal to or less than the width of the item to be compressed.

[0034] Step d: Drive the pressure plate 1 to continue moving downwards to compress the item. Once the item is fully compressed, stop moving the pressure plate 1 downwards.

[0035] Step e: Drive the two side stops 2 to move in opposite directions, so that the two side stops 2 are separated from the compressed item. Finally, drive the pressure plate 1 to move upward back to its original position, completing one compression process.

[0036] The compression method in this embodiment, through reasonable design of the compression process, can not only ensure that the width of the item remains consistent before and after compression, but also prevent the side baffle 2 from clamping the compressed item and causing it to move upward during the return process, thus ensuring the smoothness of subsequent item conveying processes and effectively improving the work efficiency of compression and packaging.

[0037] Finally, it should be noted that the compressor disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
