Description

Technical Field

[0001] This utility model relates to the field of copper clad laminate manufacturing technology, and in particular to a vacuum sealing packaging device suitable for copper clad laminate packaging. Background Technology

[0002] In the copper clad laminate industry, the board packaging process refers to packaging the cut boards according to the quantity required by the customer's order, and the packaging system is the main equipment in this process.

[0003] See Figure 1 As shown, the existing packaging system mainly includes: sheet weighing and lifting conveyor B1, packaging paper unwinding device B3, sheet conveying device B4, first sealing and cutting device B5, sheet conveying device B7, left and right sealing devices B8, wooden pallet straightening device B9, roller shutter conveying and stacking device B10, and inlet and outlet conveying devices B11 and B12. Combined with... Figures 2-3 As shown, during packaging, the packaging paper 200 is folded in half by the board conveying device B4 to package the board 300. Then, it is conveyed to the first sealing and cutting device B5 to seal the end opening of the packaging paper 200, forming the first sealing position 210. When it is conveyed to the board conveying device B7, the left and right sealing devices B8 seal the left and right openings of the packaging paper 200, forming the left sealing position 230 and the right sealing position 220. This completes the packaging of the board 300.

[0004] Combination Figure 2 , Figure 3 As shown, the problem with the existing packaging system is that after the first sealing and cutting device B5 and the left and right sealing devices B8 seal the three openings of the packaging paper 200, the resulting packaging paper 200 contains air, which leads to problems such as slippage, scratches, and uneven stacking of the board 300 during transportation. This is mainly due to the loose packaging causing slippage during transportation.

[0005] Currently, the solution to the above problem is to fix the four corners of the boards with paper corner protectors to improve the misalignment issue when stacking the boards. This measure has some effect, but manually reinforcing the four corners of the boards is time-consuming and labor-intensive. On the one hand, it increases labor costs, thereby increasing production costs; on the other hand, it leads to longer packaging times and reduces production efficiency.

[0006] Therefore, it is necessary to provide a vacuum-sealed packaging device that can solve the problem of uneven stacking of sheet materials due to stress during transportation, in order to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a vacuum sealing packaging device that can solve the problem of uneven stacking of sheet materials due to stress during transportation.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows: A vacuum sealing packaging device is provided, comprising an upper seal, a lower seal, a support mechanism, a lifting mechanism, and a vacuuming mechanism arranged opposite to each other; wherein, the support mechanism is pivotally supported at one end of the lower seal; the lifting mechanism is supported at the other end of the lower seal, and the lifting mechanism can move vertically up and down to drive the lower seal to pivot up and down relative to the support mechanism; the vacuuming mechanism includes a first driving member and a vacuum tube, the vacuum tube is installed above the highest position of the lower seal and connected to a vacuum generator, the vacuum tube is also connected to the first driving member, the first driving member is used to drive the vacuum tube to extend and retract to insert between the lower seal and the upper seal to perform vacuuming or to retract and detach from the lower seal and the upper seal.

[0009] Preferably, the support mechanism includes a rotating shaft mounted below the lower seal, with the shaft's axis perpendicular to the lower seal's axis. The bottom of the lower seal is pivotally connected to the rotating shaft, allowing it to pivot and rise around the shaft when driven by the lifting mechanism. The lower seal's downward pivoting opens the side opening of the packaging paper, facilitating the insertion of a vacuum tube into the packaging paper for vacuuming. Conversely, the lower seal's upward pivoting, engaging with the upper seal, seals the package while simultaneously clamping the vacuum tube for vacuuming.

[0010] Preferably, the support mechanism further includes a bearing seat and a shaft seat, the shaft seat being fixed below the lower seal, the rotating shaft being mounted on the shaft seat, and the bearing seat being fixed to the bottom of the lower seal and pivotally connected to the rotating shaft.

[0011] Preferably, the bearing seat includes a first fixing part and a first mounting part protruding from the first fixing part. The first mounting part has a first mounting hole. The first fixing part is fixed to the bottom of the lower seal and pivotally connected to the rotating shaft through the first mounting hole. The bearing seat includes a second fixing part and a second mounting part protruding from the second fixing part. The second mounting part has a second mounting hole. The second fixing part is fixed to the bottom of the lower seal, and the rotating shaft is installed in the second mounting hole.

[0012] Preferably, the lifting mechanism includes a second driving member, which is fixed below the lower seal and abuts against the lower seal. The second driving member can move up and down in a vertical direction to drive the lower seal.

[0013] Preferably, the vacuum tube includes a main body and connecting pipes and a flat nozzle connected to both ends of the main body. The connecting pipes are connected to the first driving member, and the flat nozzle is positioned above the highest position of the lower seal.

[0014] Preferably, the main body includes a first connecting end and a second connecting end opposite to each other. The first connecting end has an arc-shaped structure, and the second connecting end is formed by gradually narrowing from the first connecting end. The first connecting end is sealed to the connecting tube, and the second connecting end is sealed to the flat nozzle.

[0015] Preferably, the connecting tube has a cylindrical structure, the flat nozzle has a cuboid structure, and the surface of the flat nozzle is smooth, so that the flat nozzle can be easily inserted between the upper and lower seals and pulled out, and will not damage the packaging paper when pulled out.

[0016] Preferably, the vacuuming mechanism further includes a fixed bracket and an air pipe clamp, the fixed bracket being used to fix the first driving member, and the air pipe clamp being fixed to the telescopic end of the first driving member and connected to the vacuum air pipe.

[0017] Preferably, the vacuum sealing packaging device further includes a guiding mechanism, which is installed at one end away from the support mechanism and has a guide groove. The lower seal is slidably installed in the guide groove and can move up and down along the guide groove. The guide groove prevents the lower seal from shifting or tilting during the up and down movement, making the movement of the lower seal more stable.

[0018] Preferably, the guiding mechanism includes a guide seat fixed below the lower seal, the top of the guide seat is recessed with the guide groove extending in a vertical direction, and the lower seal is slidably installed in the guide groove.

[0019] Preferably, the vacuum sealing packaging device further includes a controller, which is electrically connected to the lifting mechanism and the vacuuming mechanism respectively. The controller is used to control the lifting mechanism to descend so that the lower seal pivots and descends, and to control the lifting mechanism to rise and the upper seal to descend for sealing. At the same time, the controller is also used to control the first driving member to extend so as to drive the vacuum tube to extend between the upper seal and the lower seal, and to control the first driving member to retract so as to pull out the vacuum tube. It is also used to control the vacuum tube to perform vacuuming.

[0020] Compared with existing technologies, the vacuum sealing packaging device of this utility model has a support mechanism and a lifting mechanism respectively set below both ends of the lower seal, forming a fulcrum rotation lifting structure for the lower seal. A vacuum tube is set above the highest position of the lower seal, and the vacuum tube is driven to extend and retract by a first driving member. Therefore, after the lifting mechanism descends and the lower seal descends, the first driving member drives the vacuum tube to extend into the packaging paper between the lower and upper seals to draw a vacuum. After the vacuum tube extends, the lifting mechanism rises to drive the lower seal to rise and cooperate with the upper seal to seal the packaging paper. Before the packaging paper is completely sealed, the first driving member drives the vacuum tube to retract and detach from the upper and lower seals. This achieves simultaneous sealing and vacuuming of the side opening of the packaging paper, forming a vacuum packaging inside the packaging bag to secure the product inside. When the vacuum sealing packaging device is used for packaging boards, it fixes the boards by vacuum packaging, thereby effectively solving problems such as slippage, scratches, and uneven stacking caused by stress during the transportation of the boards. Furthermore, since vacuuming is performed simultaneously during the sealing process, it does not prolong the packaging time, thus improving production efficiency and eliminating the need for additional manpower, thereby reducing labor and production costs.

[0039] Embodiments of the present invention will now be described with reference to the accompanying drawings, in which similar element reference numerals represent similar elements. It should be noted that the directional descriptions involved in the present invention, such as up, down, left, right, front, and back, indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the technical solutions of this application or / and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first," "second," etc., described are only used to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0040] Combination Figure 1 , Figures 4-18As shown, the vacuum sealing packaging device 100 provided by this utility model is particularly suitable for copper-clad laminate packaging systems, serving as a left and right sealing device to seal and vacuum the left and / or right seals of the packaging paper 200. Of course, it is not limited to use in copper-clad laminate packaging systems, but can also be used in any other products requiring vacuum sealing of packaging paper / bags.

[0041] Combination Figure 2-3 As shown, it should be noted that the vacuum sealing packaging device 100 of this application is particularly suitable for packaging large-sized copper-clad laminates 300, for example, copper-clad laminates 300 with dimensions between 1.2m x 1.38m and 1.2m x 2.2m. Understandably, it is equally feasible to use the vacuum sealing packaging device 100 to seal and package small-sized copper-clad laminates or other sheet materials.

[0042] Let's combine the following... Figures 4-7 As shown, in one embodiment of this utility model, the vacuum sealing packaging device 100 includes an upper sealing opening 110 and a lower sealing opening 120 arranged opposite to each other. The upper sealing opening 110 can move up and down in the vertical direction to cooperate with the lower sealing opening 120 to seal the packaging paper 200. The structure and movement method of the upper sealing opening 110 are conventional in the art and will not be described in detail.

[0043] In this embodiment, the vacuum sealing packaging device 100 further includes a support mechanism 130, a lifting mechanism 140, and a vacuuming mechanism 150. The support mechanism 130 and the lifting mechanism 140 are respectively located below both ends of the lower seal 120. The support mechanism 130 provides pivot support to one end of the lower seal 120, allowing the lower seal 120 to pivot relative to the support mechanism 130. The lifting mechanism 140 is supported at the other end of the lower seal 120 and can move vertically up and down to drive the lower seal 120 to pivot relative to the support mechanism 130, thereby causing the lower seal 120 to pivot away from or towards the upper seal 110. The vacuuming mechanism 150 includes a first driving member 151 and a vacuum tube 152. The vacuum tube 152 is installed above the highest position of the lower seal 120 and connected to a vacuum generator. The vacuum tube 152 is also connected to the first driving member 151. The first driving member 151 is used to drive the vacuum tube 152 to extend or retract, so that the vacuum tube 152 extends between the lower seal 120 and the upper seal 110 to evacuate the packaging paper 200 or retracts to detach from the lower seal 120 and the upper seal 110. This application, through the provision of the support mechanism 130 and the lifting mechanism 140, enables the lower seal 120 to form a fulcrum rotation lifting structure. This facilitates the insertion of the vacuum tube 152 into the packaging paper 200 for vacuuming, and allows the vacuum tube 152 to be pulled out before the packaging paper 200 is completely sealed. This allows the vacuum tube 152 to be pulled out without damaging the packaging paper 200 and without causing vacuum leakage, achieving vacuum sealing of the packaging paper 200 without prolonging the packaging time, thereby improving production efficiency.

[0044] The following is combined Figure 4-5 , Figure 8 , Figure 10-13 As shown, in one embodiment of this utility model, the support mechanism 130 includes a rotating shaft 132, which is located below the lower sealing opening 120, and the axial direction of the rotating shaft 132 is perpendicular to the axial direction of the lower sealing opening 120. One end of the lower sealing opening 120 is pivotally connected to the rotating shaft 132, thereby forming a pivotal support for the lower sealing opening 120. When the lifting mechanism 140 moves up and down in the vertical direction, it drives the lower sealing opening 120 to pivot around the rotating shaft 132 to achieve the lifting and lowering.

[0045] Continue to combine Figure 4-5 , Figure 8 , Figure 10-13As shown, in one embodiment of this utility model, the support mechanism 130 further includes a bearing seat 131 and a shaft seat 133. The shaft seat 133 is fixed below the lower sealing opening 120. In this embodiment, the shaft seat 133 is fixed to the base frame 170 below the lower sealing opening 120, but this is not a limitation. The rotating shaft 132 is fixed to or fastened to the shaft seat 133, such that the axial direction of the rotating shaft 132 is perpendicular to the axial direction of the lower sealing opening 120. The bearing seat 131 is fixed to the bottom of the lower sealing opening 120 and pivotally connected to the rotating shaft 132, thereby achieving pivotal support for the lower sealing opening 120. (See also...) Figure 4-5 As shown, when the lifting mechanism 140 descends, the end of the lower seal 120 it pushes down also descends, causing the other end of the lower seal 120 to pivot around the pivot 132, thus achieving the pivotal descent of the lower seal 120. This pivotal descent of the lower seal 120 removes support from the edge of the packaging paper 200, opening the side opening of the packaging paper 200 and facilitating the insertion of the vacuum tube 152 into the packaging paper 200 for vacuuming. Then, the lower seal 120 rises under the push of the lifting mechanism 140 and engages with the upper seal 110 to seal the packaging paper 200. During this process, the vacuum tube 152 is held in place for vacuuming; that is, vacuuming and sealing of the packaging paper 200 are performed simultaneously, thus not prolonging the packaging time and improving production efficiency.

[0046] The following is combined Figure 10-11 As shown, in this embodiment, the bearing housing 131 includes a first fixing portion 1311 and a first mounting portion 1312 protruding from the first fixing portion 1311. The first mounting portion 1312 has a through first mounting hole 1313. The inner diameter of the first mounting hole 1313 is larger than the outer diameter of the rotating shaft 132. Figure 4-5 As shown, the first fixing part 1311 is fixed to the bottom of the lower sealing opening 120 and is pivotally connected to the rotating shaft 132 through the first mounting hole 1313.

[0047] Combination Figure 12-13 As shown, in this embodiment, the bearing seat 133 includes a second fixing part 1331 and a second mounting part 1332 protruding from the second fixing part 1331. The second mounting part 1332 has a second mounting hole 1333. The inner diameter of the second mounting hole 1333 preferably corresponds to the outer diameter of the rotating shaft 132. Figure 4-5As shown, the second fixing part 1331 is fixed to the base frame 170 below the lower sealing opening 120, and the rotating shaft 132 is fastened in the second mounting hole 1333, thereby achieving a fixed connection between the rotating shaft 132 and the bearing seat 133. In one specific embodiment, two bearing seats 133 are provided, and the two bearing seats 133 are fixed to the base frame 170 below the lower sealing opening 120 at intervals. The two ends of the rotating shaft 132 are respectively fastened to the two bearing seats 133, making the installation of the rotating shaft 132 more convenient. Of course, it is not limited to using two bearing seats 133 to install the rotating shaft 132. The rotating shaft 132 can also be fixed to the bearing seat 133 in other ways.

[0048] The following is combined Figure 4-5 , Figure 9 As shown, in one embodiment of this utility model, the lifting mechanism 140 includes a second driving member 141 and a bracket 142. The bracket 142 has an L-shaped structure, but is not limited to this. The second driving member 141 is fixed to the base frame 170 below the lower sealing opening 120 via the bracket 142. Specifically, both ends of the bracket 142 are engaged and fixed to the top and side surfaces of the base frame 170, and the second driving member 141 is fixed to one end of the bracket 142. The telescopic end 1411 of the second driving member 141 abuts against the bottom of the lower sealing opening 120, and the telescopic end 1411 of the second driving member 141 can move up and down vertically, thereby driving the lower sealing opening 120 to rise and fall. In this embodiment, the telescopic end 1411 of the second driving member 141 has a relatively highest and lowest position. When the telescopic end 1411 extends to the highest position, it drives the lower sealing opening 120 to rise to a horizontal position, such as... Figure 4 As shown, the sealing of the packaging paper 200 can be achieved by being parallel to the upper sealing opening 110. The lowest position of the retracted telescopic end 1411 is not specifically limited, as long as it allows the lower sealing opening 120 to move downwards and form a certain angle with the upper sealing opening 110, such as... Figure 5 As shown, this allows the edge of the wrapping paper 200 to be unsupported, with the aim of opening the side opening of the wrapping paper 200 to facilitate the insertion of the vacuum tube 152.

[0049] In this embodiment, the second drive component 141 is preferably a large-diameter, thin-type cylinder, but it is not limited to this and other drive components can also be used.

[0050] The following is combined Figures 4-7As shown, in one embodiment of this utility model, the vacuuming mechanism 150 is positioned at the end where the lifting mechanism 140 is located, and the vacuum tube 152 is positioned higher than the highest position of the lower seal 120. Thus, when the lifting mechanism 140 descends vertically, the end of the lower seal 120 supported by the lifting mechanism 140 also descends, forming an angle with the upper seal 110. The lower seal 120 does not support the edge of the packaging paper 200, thereby facilitating the insertion of the vacuum tube 152 into the packaging paper 200.

[0051] The following is combined Figure 6-7 As shown, in one embodiment of this utility model, the vacuuming mechanism 150 further includes an air tube clamp 153 and a fixed bracket 154. The fixed bracket 154 is fixed to the existing crossbeam 155, and the first driving member 151 is fixed to the fixed bracket 154. The telescopic end of the first driving member 151 is connected to the air tube clamp 153, which clamps the vacuum tube 152. The vacuum tube 152 is positioned higher than the highest point of the lower seal 120. The first driving member 151 telescopically drives the air tube clamp 153 and the vacuum tube 152 to move horizontally back and forth, so that the vacuum tube 152 extends between the lower seal 120 and the upper seal 110 to evacuate the interior of the packaging paper 200. Figure 7 As shown, or the vacuum tube 152 can be pulled out from between the lower seal 120 and the upper seal 110, as... Figure 6 As shown.

[0052] In this embodiment, the first driving component 151 is preferably a cylinder, but it is not limited to this and other driving components can also be used.

[0053] The following is combined Figure 17-18 As shown, in one embodiment of this utility model, the vacuum tube 152 includes a main body 1521 and connecting tubes 1522 and a flat nozzle 1523 connected to both ends of the main body 1521. The main body 1521 has a first connecting end and a second connecting end. The first connecting end has an arc-shaped structure, gradually narrowing to form the second connecting end. Specifically, the sidewall of the main body 1521 gradually slopes and narrows from the first connecting end to the second connecting end. The first connecting end is sealed to the connecting tube 1522, and the second connecting end is sealed to the flat nozzle 1523. The flat nozzle 1523 has a smooth surface and a small thickness; therefore, the lower sealing opening 120 only needs to descend a small height for the flat nozzle 1523 to be inserted into the packaging paper 200 for vacuuming, and the flat nozzle 1523 will not damage the packaging paper 200 when it is pulled out.

[0054] In one specific embodiment, the side view of the main body 1521 is approximately teardrop-shaped, such as... Figure 17As shown. The connecting tube 1522 is cylindrical, and the flat nozzle 1523 is cuboid. The first connecting end of the main body 1521 is sealed to the cylindrical connecting tube 1522, and the second connecting end is sealed to the flat nozzle 1523. More specifically, the main body 1521 is preferably formed by bending a 1mm stainless steel plate, with both ends of the stainless steel plate tapering at an angle to form the second connecting end, and a port with a length of 20mm and a width of 1mm is formed at the second connecting end; simultaneously, the bending position of the stainless steel plate forms an arc-shaped first connecting end, and a port with a diameter of 10mm is provided at the first connecting end. The connecting tube 1522 is made of a stainless steel pipe with an outer diameter of 10mm, and the connecting tube 1522 is fixed to the first connecting end by welding or other methods to seal the circular port at that end. The flat nozzle 1523 is preferably formed by bending a 1mm stainless steel plate, and is fixed to the second connecting end by welding or other methods to seal the rectangular port at that end. Understandably, the shape, size, etc. of the vacuum tube 152 are not limited to those in this embodiment.

[0055] The following is combined Figure 4-5 , Figure 14-16 As shown, in one embodiment of this utility model, the vacuum sealing packaging device 100 further includes a guide mechanism 160. The guide mechanism 160 is installed at the end away from the support mechanism 130, specifically at the end near the lifting mechanism 140. The guide mechanism 160 is provided with a guide groove 161a extending vertically. The lower seal 120 is slidably installed in the guide groove 161a and can rise and fall along the guide groove 161a. The guide groove 161a prevents the lower seal 120 from shifting or tilting during its up-and-down movement, making the movement of the lower seal 120 more stable and forming a better sealing effect in conjunction with the upper seal 110.

[0056] like Figure 14-16 As shown, the guiding mechanism 160 includes a guide seat 161 and a pad 162. The guide seat 161 is fixed to the base frame 170 below the lower seal 120 via the pad 162. The pad 162 has a conventional structure. The top of the guide seat 161 is recessed with a guide groove 161a extending vertically, and the lower seal 120 is slidably installed in the guide groove 161a.

[0057] In one specific embodiment, the guide seat 161 includes a base plate 1611 and two side plates 1612. The side plates 1612 are fixed to the base plate 1611 at intervals. Notches 1613 are provided on the opposite surfaces of the side plates 1612, thus forming the guide groove 161a between the notches 1613 of the side plates 1612. A support portion 1614 is formed at the bottom of the notches 1613 of the side plates 1612. The two side walls of the lower seal 120 are slidably installed within the guide groove 161a formed between the side plates 1612. When the lower seal 120 descends to its lowest position, the lower seal 120 is supported by the support portion 1614. This structural design makes the processing and installation of the guide seat 161 more convenient. It is understood that the guide groove 161a is not limited to being formed through the side plates 1612; it is also feasible to directly recess the guide groove 161a into the integral structure of the guide seat 161.

[0058] Recombined Figures 4-9 As shown, in one embodiment of the present invention, the vacuum sealing packaging device 100 further includes a controller (not shown), which is electrically connected to the lifting mechanism 140 and the vacuuming mechanism 150 respectively, and is used to control the operation of the lifting mechanism 140 and the vacuuming mechanism 150. In one embodiment, the controller controls the lifting mechanism 140 to descend so that the lower seal 120 pivots and descends. Then, the controller controls the first drive member 151 to extend so that the vacuum tube 152 extends into the packaging paper 200 between the upper seal 110 and the lower seal 120. Next, the controller controls the lifting mechanism 140 to rise so that the lower seal 120 rises, while simultaneously controlling the upper seal 110 to descend so that the upper seal 110 and the lower seal 120 cooperate to seal the packaging paper 200. During this process, the controller controls the vacuum generator and the vacuum tube 152 to evacuate the interior of the packaging paper 200. That is, sealing the packaging paper 200 and evacuating the vacuum are performed simultaneously. When the vacuuming is completed, the controller controls the first drive member 151 to retract so as to pull out the vacuum tube 152, and continues to control the upper seal 110 and the lower seal 120 to seal the packaging paper 200 until the sealing is completed. Because the vacuum tube 152 has a smooth flat nozzle 1523, it can be easily inserted into the packaging paper 200 and pulled out from between the upper seal 110 and the lower seal 120, and it is not easy to leak vacuum when pulled out, and the flat nozzle 1523 will not damage the packaging paper 200.

[0059] The following is combined Figures 1-18 As shown, taking the application of the vacuum sealing packaging device 100 in a copper-clad laminate packaging system to package copper-clad laminates as an example, the working principle and process of the vacuum sealing packaging device 100 are explained.

[0060] In one embodiment of this utility model, the vacuum sealing packaging device 100 is the right sealing device of the copper-clad laminate packaging system, used to seal the right opening of the packaging paper 200. The structure of the other parts of the copper-clad laminate packaging system is the same as that in the prior art, and will not be described again.

[0061] Combination Figure 1-3 As shown, during the copper-clad laminate packaging process, when the packaging paper 200 and the stacked board 300 are conveyed to the first sealing and cutting mechanism B5, the first sealing and cutting mechanism B5 seals the end opening of the folded packaging paper 200. Then, the packaging paper 200 and the stacked board 300 are conveyed to the board conveying mechanism B7. At this time, the upper sealing 110 of the left sealing device B8 descends, pressing down on the left opening of the packaging paper 200, thereby sealing the left opening of the packaging paper 200 and preventing air leakage during subsequent vacuuming.

[0062] The vacuum sealing packaging device 100 seals and evacuates the right-side opening of the packaging paper 200. Specifically, the controller first controls the lifting mechanism 140 to descend, that is, the telescopic end 1411 of the second drive member 141 descends to cause the lower seal 120 to pivot around the rotating shaft 132 and descend, as shown. Figure 5 As shown, this leaves the right edge of the packaging paper 200 unsupported, and opens the right side opening of the packaging paper 200 to facilitate the insertion of the vacuum tube 152. Next, the controller controls the operation of the vacuum mechanism 150, and the first drive member 151 drives the vacuum tube 152 to extend horizontally, so that its flat nozzle 1523 extends into the packaging paper 200 between the lower seal 120 and the upper seal 110.

[0063] Next, the controller again controls the lifting mechanism 140 to operate, causing the telescopic end 1411 of the second drive member 141 to rise and push the lower seal 120. The lower seal 120 pivots around the rotating shaft 132 and rises to a horizontal position, as shown. Figure 4 As shown. Simultaneously, the controller also controls the upper seal 110 to descend, thereby pressing the right opening of the packaging paper 200 through the upper seal 110 and lower seal 120 and clamping the flat nozzle 1523 of the vacuum tube 152. The upper seal 110 and lower seal 120 seal the right opening of the packaging paper 200, while simultaneously controlling the vacuum generator to operate so that the vacuum tube 152 evacuates the interior of the packaging paper 200. Since the contact surfaces of the upper seal 110 and lower seal 120 are both made of elastic material, there will be no vacuum leakage when clamping the flat nozzle 1523 of the vacuum tube 152, nor will it damage the flat nozzle 1523 of the vacuum tube 152.

[0064] When vacuuming is complete, the upper seal 110 and lower seal 120 are not yet completely sealed to the right opening of the packaging paper 200. At this time, the controller controls the vacuuming mechanism 150 to operate again, causing its first drive component 151 to drive the vacuum tube 152 to retract horizontally, thereby forcibly pulling out the flat nozzle 1523 of the vacuum tube 152. Because the surface of the flat nozzle 1523 of the vacuum tube 152 is smooth, the packaging paper 200 will not be damaged when forcibly pulled out, and vacuum leakage is not easy when pulled out. Then, the upper seal 110 and lower seal 120 continue to seal the right opening of the packaging paper 200 until it is completely sealed.

[0065] Thus, the packaging paper 200 forms a vacuum package, thereby fixing the stacked boards 300 inside, which can effectively solve the problems of slippage, scratches, and uneven stacking caused by stress on the boards 300 during transportation.

[0066] Understandably, the vacuum sealing packaging device 100 can also be used as the left sealing device of the copper-clad laminate packaging system to seal and vacuum the left opening of the packaging paper 200; or both the left and right sealing devices can be set as the vacuum sealing packaging device 100 in this application, and both the left and right openings of the packaging paper 200 can be sealed and vacuumed at the same time.

[0067] In summary, the vacuum sealing packaging device 100 of this utility model has a support mechanism 130 and a lifting mechanism 140 respectively provided below both ends of the lower seal 120, so that the lower seal 120 forms a fulcrum rotation lifting structure, and a vacuum tube 152 is provided above the highest position of the lower seal 120. The vacuum tube 152 is driven to extend and retract by the first driving member 151. Therefore, after the lifting mechanism 140 descends and causes the lower seal 120 to descend, the first driving member 151 drives the vacuum tube 152 to extend into the packaging paper 200 between the lower seal 120 and the upper seal 110 to perform vacuuming. After the vacuum tube 152 extends in, the lifting mechanism 140 rises to drive the lower seal 120 to rise and cooperate with the upper seal 110 to seal the packaging paper 200. Before the packaging paper 200 is completely sealed, the first driving member 151 drives the vacuum tube 152 to retract and disengage from the upper seal 110 and the lower seal 120. This achieves simultaneous sealing and vacuuming of the side opening of the packaging paper 200, forming a vacuum package inside the packaging paper 200 to fix the product inside the packaging paper 200. When the vacuum sealing packaging device 100 is used for packaging boards, the board is fixed by vacuum packaging, which effectively solves the problems of slippage, scratches, and uneven stacking caused by stress during the transportation of the board. In addition, since vacuuming is carried out at the same time as sealing the packaging paper 200, the packaging time is not extended, thereby improving production efficiency and eliminating the need to increase manpower, thus reducing labor costs and production costs.

[0068] The structures of other parts of the copper-clad laminate packaging system involved in this utility model are conventional structures well known to those skilled in the art, and will not be described in detail here.

[0069] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
