Description

Technical Field

[0001] This utility model relates to the field of carpet packaging technology, and in particular to a carpet vacuum packaging machine. Background Technology

[0002] In the fields of carpet production, warehousing, and logistics, vacuum packaging technology has become one of the mainstream packaging solutions to achieve efficient space utilization, reduce storage costs, and protect carpets from moisture and dust contamination during circulation. Currently, most carpet vacuum packaging machines on the market operate on the principle of extracting air from the sealed packaging bag through a vacuum system, creating a negative pressure environment inside the bag. Then, a pressurizing mechanism applies pressure to the packaging bag and the carpet inside, causing the carpet volume to compress and ultimately achieving a heat seal, resulting in tight packaging of the carpet.

[0003] With the increasing variety of carpets, some products with special structures or materials pose challenges to existing vacuum packaging technologies. One type is carpets with hard adhesive backing, which form localized protrusions after the adhesive cures. Another type is decorative carpets with hard protrusions such as sequins and beads on the surface. In addition, some woven carpets have hard edges that can form sharp corners. During vacuum packaging, these hard parts come into point or line contact with the packaging bag, causing a sudden increase in local pressure and easily puncturing commonly used packaging bags. Packaging damage directly leads to vacuum failure, and the entry of air causes the carpet to rebound. Moisture and dust intrusion can cause dampness or contamination. Furthermore, damaged packaging is prone to further tearing during storage and transportation, causing carpet wear and tear, increasing rework costs and losses for enterprises, seriously affecting product quality and causing economic losses. Therefore, this application aims to solve the problem that existing carpets with hard adhesive backing, decorations, or hard edges are prone to puncturing the packaging during vacuum packaging, leading to vacuum failure, carpet rebound and contamination, and increased wear and tear during storage and transportation, as well as enterprise costs. A carpet vacuum packaging machine is proposed. Utility Model Content

[0004] To address the challenges posed by the increasing variety of carpet products and the unique structural features that require vacuum packaging, carpets with hard adhesive backing, decorative sequins or beads, or sharp edges are prone to point-to-line contact with the packaging bag during pressurization. This can lead to excessive localized pressure and puncture of the packaging. Once the packaging is damaged, vacuum failure and carpet rebound will occur, allowing moisture and dust to penetrate and potentially causing contamination. Furthermore, damage and wear during storage and transportation will be exacerbated, significantly increasing enterprise costs and product losses.

[0005] The technical solution of this utility model is as follows: a carpet vacuum packaging machine, including a packaging machine body, an internal placement groove, and a vacuum cover movably connected to the packaging machine body. The feature is that it also includes a fixed pressure plate, the bottom end of which contacts the top end of the carpet packaging bag placed in the placement groove, and a pressure guide groove penetrating the thickness of the fixed pressure plate is provided on the fixed pressure plate, and a plurality of pressure guide grooves are provided.

[0006] Preferably, the fixed pressure plate has a support bladder connected to its outer surface except for the upper and lower end faces. The support bladder is connected to a connecting pipe, and the connecting pipe is connected to a collecting head. The upper end face of the collecting head is connected to a conveying pipe, and the input end of the conveying pipe is connected to a pump, and the input end of the pump is connected to a connecting pipe.

[0007] Preferably, the input end of the connecting pipe is connected to a storage tank, and the lower end face of the storage tank is connected to a support plate, which is fixedly connected to the body of the packaging machine.

[0008] Preferably, a connector is connected to the outer surface of the connecting pipe, a fixing head is connected to the upper end face of the connector, a fixing slide rail is provided on one side of the fixing head, a fixing baffle is connected to the upper end face of the fixing slide rail, and the fixing slide rail is slidably connected to the fixing head.

[0009] Preferably, a connecting plate is connected to the fixed slide rail, and a rotating block is connected to one end face of the connecting plate, with an adjustment groove provided on the rotating block.

[0010] Preferably, the front and rear ends of the packaging machine body are rotatably connected to connecting strips, which are rotatably connected to the vacuum cover, and fixed handles are connected to both ends of the vacuum cover.

[0011] Preferably, a caster wheel is connected to the lower end face of the packaging machine body, and a vacuum sealing strip is connected to the upper end face of the packaging machine body.

[0012] The beneficial effects of this utility model are: 1. By using the frame structure formed by the placement groove, the huge concentrated force applied to one point on the packaging bag is distributed to several points. The force borne by each point becomes negligible, making it difficult to puncture the packaging bag. The frame structure also artificially creates a buffer zone between the packaging bag and the product. Even in the final state of vacuuming, the packaging bag is supported by the frame and the product together, rather than being completely forced to fit against all the sharp contours of the product. This can significantly reduce the possibility of sharp contours on the carpet puncturing the packaging bag. 2. When the fixed pressure plate is installed inside the placement groove, the oil inside the storage tank can be extracted by a pump and sent into the inside of the connecting pipe through the delivery pipe. The connecting pipe is used to fill the support bladder, thereby expanding the support bladder. The expanded support bladder supports the side wall of the placement groove, so that the fixed pressure plate can be supported in the placement groove, thus achieving stable installation of the fixed pressure plate. 3. By driving the fixed head to slide within the fixed slide rail, the vertical position of the fixed pressure plate can be adjusted, allowing the fixed pressure plate to be used with carpets of different thicknesses. By rotating the rotating block, the fixed pressure plate can be rotated to one side of the packaging machine body when not in use. Furthermore, the connecting plate ensures that the sealing performance of the entire vacuum packaging machine is not affected, thereby significantly reducing the overall operating cost of the vacuum packaging machine.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] refer to Figures 1-4The structure shown is a carpet vacuum packaging machine, including a packaging machine body 101, with a placement groove 106 inside the packaging machine body 101, a vacuum cover 103 movably connected to the packaging machine body 101, and a fixed pressure plate 204. The bottom end face of the fixed pressure plate 204 contacts the top face of the carpet packaging bag placed in the placement groove 106. The fixed pressure plate 204 has a pressure guide groove 205 that penetrates the thickness of the fixed pressure plate 204, and a plurality of pressure guide grooves 205 are provided.

[0017] The shapes of the fixing plate 204 and the placement groove 106 can be configured as shown in the attached figure. Figure 3 The rectangular shape shown can also be set to other shapes, such as triangles or circles. This utility model is only applicable to the situation where the placement groove 106 and the fixing plate 204 have the same shape. The shape of the pressure guide groove 205 can be set as shown in the attached figure. Figure 3 The rectangle shown can also be set to other shapes, such as a rhombus or a triangle. When the packaging machine body 101 is working, it first sucks the air out of the placement slot 106. As the air inside the placement slot 106 is sucked out, the air pressure inside the placement slot 106 drops. At this time, the air pressure inside the packaging bag is much greater than the air pressure in the placement slot 106. At this time, the packaging bag will be subjected to downward, outward, and upward forces simultaneously. The downward force towards the carpet is limited by the space occupied by the carpet itself, resulting in limited space for the packaging bag to expand downward. Similarly, the outward force is limited by the side wall of the placement slot 106 and the carpet itself. However, the upward force towards the fixed pressure plate 204 will expand upward due to the presence of the pressure guide groove 205 to fill the space formed by the decrease in external air pressure. When the packaging bag expands to its limit, it will be pressed against the placement slot 106 on the fixed pressure plate 204. The resulting grid structure provides support, creating a stable shape fixed by the grid. Since the bag opening is placed under the vacuum strip 105 and not sealed, high-pressure air inside the bag escapes through this opening, flowing into the low-pressure vacuum chamber and eventually being drawn away by the vacuum pump inside the packaging machine body 101. Once the air inside the bag is removed, the bag is pressed tightly against the fixed pressure plate 204 under atmospheric pressure, simultaneously compressing the carpet from above. The frame structure formed by the placement groove 106 distributes the immense concentrated force applied to one point on the bag to several points, making the force on each point negligible and unlikely to puncture the bag. The frame structure also artificially creates a buffer zone between the bag and the product. Even in the final vacuum state, the bag is supported by both the frame and the product, rather than being forced to conform completely to all the sharp contours of the product, thus significantly reducing the possibility of sharp contours on the carpet puncturing the bag.

[0018] Furthermore, a support bladder 401 is connected to the outer surface of the fixed pressure plate 204 except for the upper and lower end faces. A connecting pipe 402 is connected to the support bladder 401. A collection head 403 is connected to the connecting pipe 402. A conveying pipe 404 is connected to the upper end face of the collection head 403. A pump is connected to the input end of the conveying pipe 404, and a connecting pipe 408 is connected to the input end of the pump.

[0019] Furthermore, the input end of the connecting pipe 408 is connected to a storage tank 406, and the lower end face of the storage tank 406 is connected to a support plate 407, which is fixedly connected to the packaging machine body 101.

[0020] The storage tank 406 contains liquid, which can be perfluoropolyether oil or other oils, such as high vacuum silicone oil or mineral oil. When the fixed pressure plate 204 is installed inside the placement groove 106, the oil inside the storage tank 406 can be extracted by a pump and sent into the connecting pipe 402 through the delivery pipe 404. The connecting pipe 402 is used to fill the support bladder 401, thereby expanding the support bladder 401. The expanded support bladder 401 supports the side wall of the placement groove 106, so that the fixed pressure plate 204 can be supported in the placement groove 106, thus achieving stable installation of the fixed pressure plate 204.

[0021] Furthermore, a connector 303 is connected to the outer surface of the connecting pipe 402, a fixing head 203 is connected to the upper end face of the connector 303, a fixing slide rail 301 is provided on one side of the fixing head 203, a fixing baffle 302 is connected to the upper end face of the fixing slide rail 301, and the fixing slide rail 301 is slidably connected to the fixing head 203.

[0022] Among them, a rotating head 206 is rotatably connected to one end face of the fixed head 203. The rotating head 206 is fitted onto the outer surface of the connecting tube 402, and the rotating head 206 is fixedly connected to the support bladder 401. The fixed head 203 can be driven to slide within the fixed slide rail 301 to adjust the vertical position of the fixed pressure plate 204, thereby allowing the fixed pressure plate 204 to be used with carpets of different thicknesses, which can significantly reduce the overall operating cost of the vacuum packaging machine.

[0023] Furthermore, a connecting plate 202 is connected to the fixed slide rail 301, and a rotating block 201 is connected to one end face of the connecting plate 202. An adjustment groove 405 is provided on the rotating block 201.

[0024] Furthermore, connecting strips 102 are rotatably connected to the front and rear ends of the packaging machine body 101. The connecting strips 102 are rotatably connected to the vacuum cover 103. Fixed handles 104 are connected to both ends of the vacuum cover 103.

[0025] Furthermore, a caster wheel 5 is connected to the lower end face of the packaging machine body 101, and a vacuum pressure strip 105 is connected to the upper end face of the packaging machine body 101.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
