Description

Technical Field

[0001] This invention relates to the technical field of vacuum insulation panels, and more specifically to an automatic bagging and sealing device for the production of vacuum insulation panels. Background Technology

[0002] Vacuum insulation panels (VIP panels) are a type of vacuum insulation material, composed of a core filling material and a vacuum protective surface layer. They effectively prevent heat transfer caused by air convection, thus significantly reducing the thermal conductivity to 0.002-0.004 W / mK, which is 1 / 10 of the thermal conductivity of traditional insulation materials.

[0003] Currently, when producing vacuum insulation panels, companies need to manually open the vacuum barrier film, transfer the core board inside the film, and position it as centrally as possible before using a vacuum sealer. As can be seen, manual processing accounts for a significant portion of the edge-sealing process for vacuum insulation panels, making it highly dependent on human skill. This increases labor costs and hinders production efficiency and economic benefits for companies. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic bagging and sealing device for the production of vacuum insulation panels, so as to solve the above-mentioned defects caused by the prior art.

[0005] An automatic bagging and sealing device for vacuum insulation panel production includes an opening and closing mechanism and a displacement mechanism, wherein...

[0006] The opening and closing mechanism is used to automatically expand the vacuum barrier film to facilitate the automatic insertion of the core board, and then automatically close the vacuum barrier film to facilitate subsequent vacuum sealing.

[0007] The displacement mechanism is located behind the opening and closing mechanism and is used to adjust the spatial orientation of the opening and closing mechanism, the vacuum barrier membrane, and the core plate, so as to facilitate the placement of the vacuum barrier membrane into the opening and closing mechanism and the sliding of the core plate into the vacuum barrier membrane.

[0008] Preferably, the opening and closing mechanism includes a mounting box, guide strips, suction strips, linkage blocks, and a hydraulic cylinder. The mounting box has two pairs of connecting strips symmetrically arranged on the left and right sides. Each pair of connecting strips is vertically arranged and parallel to each other front and back. The two connecting strips are connected to the front and rear sides of the mounting box respectively by a set of connecting pins. A return spring is fitted onto the outside of the mounting box via the connecting pins. There is one pair of suction strips arranged horizontally front and back. The left and right ends of each suction strip are connected to the upper ends of adjacent connecting strips. Rectangular suction grooves are evenly distributed on the inner side of each suction strip. Suction pipes are connected to both sides of each suction strip and connect to an external negative pressure air source. There are two pairs of linkage blocks arranged symmetrically on the left and right sides. Each pair of linkage blocks is connected to the lower end of an adjacent pair of connecting strips. The vertical cross-section of the linkage block is an isosceles trapezoidal structure. A pair of hydraulic cylinders are provided and symmetrically distributed on the front and rear sides of the mounting box. The hydraulic cylinder is vertically upward and connected to the outside of the mounting box through a fixing plate. The piston rod of the hydraulic cylinder is horizontally connected to a lifting strip. Both ends of the lifting strip are connected to an "L"-shaped lifting frame. The lower ends of two adjacent lifting frames are connected to a "T"-shaped lifting plate. A pair of lifting blocks are symmetrically connected in the middle of the lifting plate. The vertical cross-section of the lifting block is a right-angled trapezoidal structure. The lower inclined waist surface of the adjacent linkage block slides in contact with the upper inclined waist surface of the lifting block.

[0009] Preferably, the displacement mechanism includes a mounting plate, a second fixing plate, and a second hydraulic cylinder. The mounting plate has a rectangular discharge port in the middle. The second fixing plate has a pair of cylinders symmetrically installed on the left and right sides of the discharge port. The second hydraulic cylinder has a pair of cylinders symmetrically distributed on the left and right sides. Adjacent second hydraulic cylinders are vertically connected to the front of the second fixing plate. The piston rod of the second hydraulic cylinder is connected to a hinge seat, and a "┌"-shaped hinge frame is hinged to the hinge seat. The rear of the second fixing plate is connected to a hinge seat, and a "│"-shaped hinge frame is hinged to the hinge seat. The other end of the first hinge frame on the same side is hinged to the other end of the second hinge frame. The first hinge frames on both sides are connected to the left and right sides of the mounting box.

[0010] Preferably, a pair of hinged bars are hinged to the middle of the connecting bar, and a linkage bar is hinged to the other end of the pair of hinged bars. An "L"-shaped adjustment plate is connected in parallel on the inner wall of the linkage bar, and a linkage column is connected vertically on the outer wall of the linkage bar. The front and rear sides of the mounting box are provided with through grooves that match the movement trajectory of each linkage column. Rectangular lifting grooves are symmetrically provided on the left and right sides of the lifting bar. Adjacent linkage columns slide through the through grooves and lifting grooves.

[0011] Preferably, a pair of guide strips are symmetrically connected to the inner wall of the mounting box, and the inner wall of the guide strips is provided with V-shaped guide grooves, with the guide grooves on the same side corresponding to the top of the lifting plate.

[0012] Preferably, the mounting box is designed to be vertically continuous, the middle of the lifting plate is provided with a rectangular clearance groove, and a pair of lifting blocks on the lifting plate are symmetrically distributed on the front and rear sides of the clearance groove.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. When the unexpanded vacuum barrier membrane is placed between the two adsorption strips, the piston rods of the two hydraulic cylinders retract and drive the corresponding lifting strips and the lifting blocks on the left and right sides to move downwards, thereby bringing the pair of linkage blocks and connecting strips on the same side closer to each other, and thus bringing the two adsorption strips closer to each other and adsorbing them on the front and back sides of the vacuum barrier membrane.

[0015] 2. When the unexpanded vacuum barrier membrane is adsorbed between the two adsorption strips, the piston rods of the two hydraulic cylinders extend and drive the corresponding lifting strips and the lifting blocks on the left and right sides to move upward, thereby pushing the pair of linkage blocks and connecting strips on the same side away from each other, thereby driving the two adsorption strips to move away from each other and expand the vacuum barrier membrane.

[0016] 3. After the core plate is inserted into the expanded vacuum barrier membrane, the piston rods of the two hydraulic cylinders retract and drive the corresponding lifting strips and the lifting blocks on the left and right sides to move downward, thereby bringing the pair of linkage blocks and connecting strips on the same side closer to each other, and thus bringing the two adsorption strips at the front and rear closer to each other and closing the opening of the vacuum barrier membrane.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figures 1 to 6 As shown, an automatic bagging and sealing device for vacuum insulation panel production includes an opening and closing mechanism 10 and a displacement mechanism 20, wherein...

[0028] The opening and closing mechanism 10 is used to automatically open the vacuum barrier film 30 to facilitate the automatic insertion of the core board 40, and then automatically close the vacuum barrier film 30 to facilitate subsequent vacuum sealing.

[0029] The displacement mechanism 20 is located on the rear side of the opening and closing mechanism 10 and is used to adjust the spatial orientation of the opening and closing mechanism 10, the vacuum barrier membrane 30 and the core plate 40, so as to put the vacuum barrier membrane 30 into the opening and closing mechanism 10 and slide the core plate 40 into the vacuum barrier membrane 30.

[0030] In this embodiment, the opening and closing mechanism 10 includes a mounting box 101, guide strips 102, suction strips 106, a linkage block 112, and a hydraulic cylinder 113. The mounting box 101 has two pairs of connecting strips 103 symmetrically arranged inside, each pair being vertically arranged and parallel to each other. The two connecting strips 103 are connected to the front and rear sides of the mounting box 101 respectively via a set of connecting pins 104. A return spring 105 is fitted onto the outside of the mounting box 101 via the connecting pins 104. The suction strips 106 are arranged in pairs horizontally, with their left and right ends connected to the upper ends of adjacent connecting strips 103. Rectangular suction grooves 106a are evenly distributed on the inner side of the suction strips 106. Suction pipes 107 are connected to both sides of the suction strips 106, and these suction pipes 107 are connected to an external negative pressure air source. The linkage block 112 has two... The linkage blocks 112 are symmetrically arranged on both sides, and each pair of linkage blocks 112 is connected to the lower end of an adjacent pair of connecting strips 103. The vertical cross-section of the linkage block 112 is an isosceles trapezoidal structure. A pair of hydraulic cylinders 113 are provided and symmetrically distributed on the front and rear sides of the mounting box 101. The hydraulic cylinders 113 are vertically arranged and connected to the outside of the mounting box 101 through a fixing plate 114. The piston rod of the hydraulic cylinder 113 is horizontally connected to a lifting strip 115. Both ends of the lifting strip 115 are connected to an "L"-shaped lifting frame 116. The lower ends of two adjacent lifting frames 116 are connected to a "T"-shaped lifting plate 117. A pair of lifting blocks 118 are symmetrically connected to the middle of the lifting plate 117. The vertical cross-section of the lifting block 118 is a right-angled trapezoidal structure. The lower inclined waist surface of the adjacent linkage block 112 slides in contact with the upper inclined waist surface of the lifting block 118. The piston rods of the two hydraulic cylinders 113 extend and drive the corresponding lifting bars 115 and the lifting blocks 118 on the left and right sides to move upward, thereby pushing the pair of linkage blocks 112 and connecting bars 103 on the same side away from each other, and thus driving the two adsorption bars 106 on the front and rear to move away from each other, so as to facilitate the automatic placement of the core plate 40 inside the mounting box 101. Afterwards, the piston rods of the two hydraulic cylinders 113 retract and drive the corresponding lifting bars 115 and the lifting blocks 118 on the left and right sides to move downward, thereby bringing the pair of linkage blocks 112 and connecting bars 103 on the same side closer to each other, and thus bringing the two adsorption bars 106 on the front and rear closer to each other, so as to facilitate subsequent vacuum sealing.

[0031] In this embodiment, the displacement mechanism 20 includes a mounting plate 201, a second fixing plate 202, and a second hydraulic cylinder 203. The mounting plate 201 has a rectangular discharge port 201a in the middle. The second fixing plate 202 has a pair symmetrically mounted on the left and right sides of the discharge port 201a. The second hydraulic cylinder 203 has a pair symmetrically distributed on the left and right sides, with adjacent second hydraulic cylinders 203 vertically connected to the front of the second fixing plate 202. The piston rod of 3 is connected to a hinge seat 204 at its end, and a "┌"-shaped hinge frame 205 is hinged on the hinge seat 204. The rear of the fixing plate 202 is connected to a hinge seat 206, and a "│"-shaped hinge frame 207 is hinged on the hinge seat 206. The other end of the hinge frame 205 on the same side is hinged to the other end of the hinge frame 207. The hinge frames 205 on both sides are connected to the left and right sides of the mounting box 101 respectively. The piston rods of the two hydraulic cylinders 203 extend and drive the corresponding hinge frame 205, opening and closing mechanism 10 and vacuum barrier membrane 30 to rotate upward and backward by 90 degrees, so as to adjust them to a horizontal state and facilitate the core plate 40 to slide forward into the empty vacuum barrier membrane 30. The piston rods of the two hydraulic cylinders 203 retract and drive the corresponding hinge frame 205 and opening and closing mechanism 10 to rotate downward and forward by 90 degrees, so as to adjust them to a vertical state and facilitate the vacuum insulation plate to flow downward out of the opening and closing mechanism 10, and the empty vacuum barrier membrane 30 to be placed into the opening and closing mechanism 10.

[0032] In this embodiment, a pair of hinged bars 108 are hinged to the middle of the connecting bar 103, and a linkage bar 109 is hinged to the other end of the pair of hinged bars 108. An "L"-shaped adjustment plate 110 is connected in parallel to the inner wall of the linkage bar 109, and a linkage column 111 is connected vertically to the outer wall of the linkage bar 109. The front and rear sides of the mounting box 101 are provided with through grooves 101a that match the movement trajectory of each linkage column 111. The left and right sides of the lifting bar 115 are symmetrically provided with rectangular lifting grooves 115a. Adjacent linkage columns 111 slide through the through grooves 101a and lifting grooves 115a. The piston rods of the two hydraulic cylinders 113 extend and drive the corresponding lifting bars 115 and the linkage columns 111 on the left and right sides to move upward, thereby pushing the adjustment plates 110 on the left and right sides away from each other, so as to facilitate the automatic placement of the core plate 40 inside the mounting box 101. Then, the piston rods of the two hydraulic cylinders 113 retract and drive the corresponding lifting bars 115 and the linkage columns 111 on the left and right sides to move downward, thereby pushing the adjustment plates 110 on the left and right sides closer to each other, thereby adjusting the core plate 40 that has slid into the vacuum barrier membrane 30 to the center position, so as to facilitate subsequent vacuum sealing and folding.

[0033] In this embodiment, a pair of guide strips 102 are symmetrically connected to the inner wall of the mounting box 101. The inner wall of each guide strip 102 has a V-shaped guide groove 102a, with the guide groove 102a on the same side positioned directly above the lifting plate 117. The guide grooves 102a on both sides can limit the left and right edges of the vacuum barrier film 30, and the lifting plates 117 on both sides can limit the lower edge of the vacuum barrier film 30.

[0034] In this embodiment, the mounting box 101 is designed to be vertically continuous, and the lifting plate 117 has a rectangular clearance groove 117a in the middle. A pair of lifting blocks 118 on the lifting plate 117 are symmetrically distributed on the front and rear sides of the clearance groove 117a. After the vacuum insulation board is sealed, it can automatically flow away under its own gravity, passing through the bottom of the mounting box 101, the clearance groove 117a, and the discharge port 201a in sequence.

[0035] In practical applications, this automatic bagging and sealing device for vacuum insulation panel production demonstrates the following:

[0036] Step 1: The piston rods of the two hydraulic cylinders 113 extend and drive the corresponding lifting bars 115 and the lifting blocks 118 on the left and right sides to move upward, thereby pushing the pair of linkage blocks 112 and connecting bars 103 on the same side away from each other, thereby driving the two suction bars 106 at the front and rear to move away from each other.

[0037] Step 2: The piston rods of the two hydraulic cylinders 203 on the left and right retract and drive the corresponding hinge frame 205 and opening and closing mechanism 10 to rotate downward and forward 90 degrees to adjust them to a vertical state.

[0039] Step 4: The piston rods of the two hydraulic cylinders 113 retract and drive the corresponding lifting strips 115 and the lifting blocks 118 on the left and right sides to move downward, thereby making the pair of linkage blocks 112 and connecting strips 103 on the same side approach each other, and thus making the two adsorption strips 106 approach each other and adsorb on the front and rear sides of the vacuum barrier membrane 30.

[0040] Step 5: The piston rods of the two hydraulic cylinders 113 extend and drive the corresponding lifting bars 115 and the lifting blocks 118 on the left and right sides to move upward, thereby pushing the pair of linkage blocks 112 and connecting bars 103 on the same side away from each other, thereby driving the two adsorption bars 106 to move away from each other and opening the vacuum barrier membrane 30.

[0041] Step 6: The piston rods of the two hydraulic cylinders 203 extend and drive the corresponding hinge frame 205, opening and closing mechanism 10 and vacuum barrier diaphragm 30 to rotate upward and backward 90 degrees to adjust them to a horizontal state.

[0042] Step 7: Slide the forward-moving core plate 40 horizontally into the interior of the expanded vacuum barrier membrane 30;

[0043] Step 8: The piston rods of the two hydraulic cylinders 203 retract and drive the corresponding hinge frame 205, opening and closing mechanism 10, vacuum barrier membrane 30 and core plate 40 to rotate downward and forward 90 degrees to adjust them to a vertical state.

[0044] Step 9: The piston rods of the two hydraulic cylinders 113 retract and drive the corresponding lifting strips 115 and the lifting blocks 118 on the left and right sides to move downward, thereby making the pair of linkage blocks 112 and connecting strips 103 on the same side move closer to each other, thereby making the two adsorption strips 106 move closer to each other and close the opening of the vacuum barrier membrane 30.

[0045] Step 10: Vacuum seal the edges of the vacuum barrier film 30 containing the core board 40 using a vacuum sealing machine;

[0046] Step 11: The piston rods of the two hydraulic cylinders 113 extend and drive the corresponding lifting bars 115 and the lifting blocks 118 on the left and right sides to move upward, thereby pushing the pair of linkage blocks 112 and connecting bars 103 on the same side to move away from each other. The vacuum insulation board obtained, under its own gravity, passes through the bottom of the mounting box 101, the clearance groove 117a and the discharge port 201a in sequence and flows away automatically.

[0047] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
