DETAILED DESCRIPTION

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 making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-8 The present invention provides a technical solution: a heat-sealing packaging device for glass fiber cloth, comprising a lowering structure 1, a heat-sealing structure, two pairs of dragging and dropping structures 5, a pair of pads 6, a pair of pad arms 7 and a pair of picking units 8; the lowering structure 1 is used to carry the rolled packaging plastic, and to perform lifting and lowering transportation, the heat-sealing structure is fixedly arranged on the lowering structure 1 and is located below the packaging plastic, the heat-sealing structure is used to drive the packaging plastic to fold relative to each other and seal, the two pairs of dragging and dropping structures 5 are symmetrically arranged on the heat-sealing structure, a pair of pads 6 are symmetrically arranged on one of the pairs of dragging and dropping structures 5, the dragging and dropping structure 5 is used to limit the rolled fiber cloth and can complete the unloading after packaging, a pair of pad arms 7 are respectively symmetrically arranged on the pads 6, a pair of picking units 8 are symmetrically arranged on the hot air structure, and the picking units 8 can contact the packaging plastic, and the picking units 8 are used to pull the packaging plastic.

[0022] As a preferred solution, further, the lowering structure 1 includes a base 11, a conveyor belt main body 12, a carriage 13, a first electric slide rail 14, a lifting rod 15, and a lowering unit 16; the conveyor belt main body 12 is fixedly arranged on the upper wall of the right end of the base 11 and near the front end, one end of the carriage 13 is fixedly arranged on the upper wall of the right end of the base 11 and behind the conveyor belt main body 12, the other end of the carriage 13 is obliquely located on the left side of the conveyor belt main body 12, and the other end of the carriage 13 has a certain height. A force application groove is provided in the middle of the other end of the carriage 13. The first electric slide rail 14 is fixedly arranged on the upper wall of the rear end of the base 11 and in front of the carriage 13. One end of the lifting rod 15 is fixedly arranged on the first electric slide rail 14, and the lifting rod 15 moves left and right. The lifting rod 15 is a rectangular rod body, and the lowering unit 16 is movably arranged on the rod of the lifting rod 15; supported by the base 11, the packaged rolled fiber cloth can be moved by the conveyor belt main body 12. The lowering unit 16 is driven to move by the first driving slide rail and limited by the carriage 13 and the lifting rod 15, so that the lowering unit 16 is lifted and lowered synchronously during the movement.

[0023] Specifically, the overall structure is supported by the base 11. The conveyor belt main body 12 receives the fiber cloth roll after packaging and completes the discharging and conveying. The first electric slide rail 14 drives the lifting rod 15 to move left and right, driving the lowering unit 16 to move horizontally synchronously; the guide roller 166 of the lowering unit 16 penetrates through the force application groove of the carriage 13. Using the inclination angle of the carriage 13, during the horizontal movement of the lowering unit 16, through the sliding of the guide roller 166 along the force application groove, the vertical lifting movement is synchronously realized, so as to adapt to plastic films of different heights and upper and lower positions; through the linkage limit of the first electric slide rail 14 and the inclined carriage 13, the compound movement of the horizontal movement and vertical lifting of the lowering unit 16 is realized, accurately controlling the lowering position, tension of the packaging plastic and the replacement of the plastic film, and improving the automation degree and stability of the packaging process.

[0024] As a preferred solution, further, the lowering unit 16 includes a sleeve 161, a chassis 162, a first motor 163, a roller shaft 164, a nut 165, and a guide roller 166; one end of the sleeve 161 is movably sleeved on the lifting rod 15, the chassis 162 is fixedly arranged on the other end of the sleeve 161 and in front of the lifting rod 15, the first motor 163 is fixedly arranged in the chassis 162, one end of the roller shaft 164 is connected to the driving end of the first motor 163, a packaging plastic roll is detachably sleeved on the roller shaft 164, the nut 165 is detachably screwed on the roller shaft 164, one end of the guide roller 166 is movably connected to the rear side wall of one end of the sleeve 161, and the other end of the guide roller 166 movably penetrates through the force application groove of the carriage 13; as the guide roller 166 rises with the inclination of the carriage 13 in the carriage 13, the sleeve 161 is lifted on the limiting rod. The first motor 163 can drive the roller shaft 164 to rotate, and the rolled plastic film can be installed on the roller shaft 164 through the nut 165.

[0025] Specifically, the packaging plastic roller is sleeved on the roller shaft 164 and fixed by tightening the nut 165 to achieve quick clamping. The guide roller 166 forms a limit fit with the carriage 13 through the force application groove to ensure the stability when the lowering unit 16 moves along the inclined direction of the carriage 13. When the first electric slide rail 14 drives the lifting rod 15 to move horizontally, the guide roller 166 slides along the inclined force application groove of the carriage 13. Due to the height difference at the inclined end of the carriage 13, the sliding track of the guide roller 166 forces the sleeve 161 to move up and down synchronously along the lifting rod 15, thereby adjusting the height position of the packaging plastic roller, driving the roller shaft 164 to rotate, releasing the packaging plastic film, and achieving continuous feeding. The detachable design of the nut 165 supports the quick replacement of the packaging plastic roll and improves the versatility of the equipment. The linkage structure between the guide roller 166 and the carriage 13 enables the lowering unit 16 to automatically complete the lifting during the horizontal movement, simplifies the mechanical transmission structure, and improves the packaging efficiency.

[0026] As a preferred solution, furthermore, the heat-sealing structure includes two folding components 2, a cutting unit 3, and a bearing table 4. The two folding components 2 are symmetrically arranged at the left end of the base 11 and on the left side of the conveyor belt main body 12. The cutting unit 3 is fixedly arranged between the left ends of the folding components 2. The bearing table 4 is fixedly arranged on the upper wall of the base 11 and between the folding components 2. The folding components 2 are used for folding the packaging plastic and applying force during heat-sealing. The cutting unit 3 is used for cutting the plastic during heat-sealing. The bearing table 4 is used for bearing the fiber cloth roller to be packaged and bearing one end of it to be flipped by the folding components 2. Through the folding components 2, the rolled fiber cloth can be flipped and clamped, and the plastic film can be folded in half and heat-sealed outside the fiber cloth. Through the cutting unit 3, the plastic film can be cut during the heat-sealing process. Through the bearing table 4, the space at the bottom between the folding components 2 is borne, and one end of the fiber cloth is placed vertically on the bearing table 4.

[0027] Specifically, the fiber cloth roller is placed on the dragging structure 5 and supported by one end on the bearing table 4. When the folding arms 22 of the two folding components 2 are in the relative flipping state, the cloth roller is flipped and clamped between the dragging structures 5, and the cloth roller is perpendicular to the bearing table 4. At the same time, the packaging plastic film is driven to be folded from both sides of the fiber cloth roller to the middle to form a package around the fiber cloth roller. After folding, the first electric heating plate 23 and the second electric heating plate 33 are respectively in contact with the cushion table 6 and the cushion arm 7 for force application and extrusion to achieve hot melt sealing in the shape of a portal frame. After heat-sealing, the cutter 36 of the cutting unit 3 synchronously contacts the cushion table 6 to cut the plastic film to form the separation of individual packages. The automatic folding and heat-sealing of the plastic film are achieved through the symmetrically arranged folding components 2, avoiding manual intervention and improving the packaging efficiency. The linkage design between the bearing table 4 and the folding components 2 ensures the stability of the fiber cloth roller during the packaging process and adapts to rolled products with different diameters. The integrated design of the cutting unit 3 and the heat-sealing mechanism achieves the synchronous completion of "heat-sealing and cutting".

[0028] As a preferred solution, further, the folding component 2 includes a folding frame 21, a pair of folding arms 22, a first electric heating plate 23, a mounting seat 24, a second motor 25, a pair of linkage arms 26, a pair of first driving arms 27, and a second driving arm 28; the folding frame 21 is T-shaped, one end of the folding frame 21 is fixedly arranged on the upper wall of the base 11, a pair of folding arms 22 are both L-shaped, one end of a pair of folding arms 22 is respectively movably arranged on the folding frame 21, and the folding arms 22 are symmetrically staggered on the front and back sides of the folding arms 22 respectively, the other ends of a pair of folding arms 22 are respectively oppositely parallel in the reverse direction, the first electric heating plate 23 is fixedly arranged on the upper wall of the other end of one of the folding arms 22 and is located on the left side of the folding frame 21, one end of the mounting seat 24 is fixedly connected to the left side wall of one end of the folding frame 21, and the other end of the mounting seat 24 is located on the left side of the folding frame 21, the other end of the mounting seat 24 is located below the other end of one of the folding arms 22, and the other end of the mounting seat 24 is concave, the second motor 25 is fixedly arranged on the front side of the other end of the mounting seat 24, one end of a pair of linkage arms 26 is respectively movably connected to one end of the folding arms 22, and the linkage arms 26 are oppositely staggered, one end of a pair of first driving arms 27 is respectively movably connected to the driving end of the second motor 25 and the rear side wall of the other end of the mounting seat 24, and the other ends of the first driving arms 27 are oppositely parallel in the reverse direction, both ends of the second driving arm 28 are respectively movably connected to the first driving arms 27, and the second driving arm 28 is located between the first driving arms 27, the second driving arm 28 is located in the middle of the other end of the mounting seat 24, and the other ends of the linkage arms 26 are respectively movably connected between the second driving arm 28 and the first driving arms 27; the second motor 25 on the mounting seat 24 drives one of the first driving arms 27 to rotate, and by means of the second driving arm 28, the other first driving arm 27 is driven to rotate, achieving a rotation effect similar to that of an automobile crankshaft, so as to drive the two staggered linkage arms 26 to swing alternately, and finally drive the staggered and symmetrically arranged folding arms 22 to relatively flip on the folding frame 21.

[0029] Specifically, the driving shaft of the second motor 25 rotates, driving the first driving arm 27 connected thereto, and this first driving arm 27 is connected to the other first driving arm 27 through the second driving arm 28 to achieve synchronous movement, forming a reverse linkage effect similar to that of an automobile crankshaft. When the two first driving arms 27 swing in the reverse direction, the two folding arms 22 are respectively pushed and pulled by the linkage arms 26 to rotate around the folding frame 21; since the two folding arms 22 are symmetrically staggered in the front and back, their moving directions are opposite, so that the reversely parallel ends of the extending ends gradually approach each other, realizing the folding and clamping of the packaging plastic and applying force for heat sealing; the reverse synchronous movement of the two folding arms 22 realizes flipping, folding, clamping, sealing, cloth roller transposition, and facilitating the discharging after packaging.

Compensation grooves are arranged in the middle parts of both ends of the turning arm 32. The second electric heating plate 33 is fixedly arranged on the middle part of the turning arm 32, and the second electric heating plate 33 is relatively fitted with the left ends of the pair of first electric heating plates 23. After the second electric heating plate 33 and the first electric heating plate 23 are relatively fitted, they form a portal frame.

One ends of the pair of first hydraulic cylinders 35 are respectively movably connected to the other ends of the folding arms 22, and the telescopic ends of the first hydraulic cylinders 35 are respectively inclined to the right and movably connected to the movable seat 34. The cutter 36 is fixedly arranged on the middle part of the turning arm 32 and on the left side of the turning arm 32. The cutting edge of the cutter 36 is on the same plane as the upper arm of the second electric heating plate 33. By the telescopic movement of the first hydraulic cylinder 35, the turning arm 32 is driven to turn on the vertical rod 31 by means of the movable seat 34, so that the second electric heating plate 33 can be docked with the first electric heating plate 23 or turned below the first electric heating plate 23, which is convenient for the cloth roller to be put in from other equipment.

[0031] Specifically, when the telescopic end of the first hydraulic cylinder 35 extends out, the turning arm 32 is pushed to turn upward around the vertical rod 31 through the movable seat 34; the second electric heating plate 33 in the middle of the turning arm 32 gradually fits with the first electric heating plate 23 of the folding arm 22 to form a closed portal heat-sealing frame; the first electric heating plate 23 and the second electric heating plate 33 are electrified and heated to perform hot-melt sealing on the edges of the packaging plastic wrapping the fiber cloth roller.

[0038] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0039] S1. The equipment is stably placed through the base 11. After the equipment is powered on, the first electric slide rail 14 in the lower structure 1 can be driven to drive the lifting rod 15 to move left and right, and the guide roller 166 in the lowering unit 16 is stressed in the inclined carriage 13, so that the sleeve 161 can move up and down on the lifting rod 15 with the translation to adjust the height; the packaging plastic film can be sleeved on the roller shaft 164 and limited and fixed by the nut 165, and then the plastic film is moved above the bearing table 4 by the limit of the carriage 13; then the first motor 163 in the chassis 162 is driven to drive the roller shaft 164 to rotate, and the plastic film is rotated and lowered by a certain length. S2. Secondly, the folding assembly 2 is driven to relatively turn the folding arms 22, so that the picking unit 8 on the folding arms 22 faces the plastic film. With the imaging of the camera 83, the turning angle of the folding arms 22 is controlled and the second electric slide rail 81 is driven to lift the mechanical claw body 82, and the mechanical claw body 82 clamps the lower end of the plastic film. With the turning and resetting of the folding arms 22, the plastic film is pulled to realize traction, so that the plastic film covers the folding arms 22 on the left side of the folding frame 21 and the dragging and placing structure 5. S3. Then the plastic film is moved to the right and lowered by a certain length, so that the plastic film covers the bearing table 4. S4. The cutting unit 3 at the left end of the folding assembly 2 is driven. By the contraction of the first hydraulic cylinder 35, the turning arm 32 is driven to turn on the vertical rod 31 by the movable seat 34, so that the second electric heating plate 33 and the cutter 36 are located below the folding arms 22, that is, the opening at the left end of the folding arms 22 is opened, which is convenient for placing the cloth roller on the dragging and placing structure 5 between the folding arms 22 at the left end of the folding assembly 2, and the cloth roller is located above the traction plastic film, and then the turning arm 32 and the cutter 36 are reset. S5. At this time, the cloth roller is limited between the symmetrically arranged carrier rollers 54 and cannot move forward or backward; and according to the diameter of the cloth roller, the second hydraulic cylinder 55 can be driven to expand and contract. With the movable connection between the second hydraulic cylinder 55 and the linkage shaft 53, the swing arm 52 is driven to flip on the mounting rod 51 to adjust the relative inclination angle and spacing of the carrier rollers 54; S6. Then, by driving the second motor 25 in the folding assembly 2, the second motor 25 drives one of the first driving arms 27 to rotate, and the two first driving arms 27 are symmetrically connected in the reverse direction through the second driving arm 28 to form an effect similar to a crankshaft, which can drive the two linkage arms 26 to push and pull the folding arms 22 respectively to achieve relative flipping on the folding frame 21; furthermore, through the relative movement of the dragging and placing structure 5, the cloth roller is driven to flip, clamp and limit on the carrier table 4, and at the same time, the flipping and folding of the plastic film and the fitting after folding are realized. The first electric heating plate 23 and the second electric heating plate 33 form a portal frame to clamp the plastic film on the cushion table 6 and the cushion arm 7. Since the folding arms 22 on the left and right sides of the folding frame 21 are staggered and cannot be fitted after flipping, the cushion arm 7 and the cushion table 6 are used to dock and clamp with one pair of folding arms 22; S7. After clamping, the front, rear and upper sides of the cloth roller are clamped and heat-sealed. The lower part of the cloth roller is blocked as a whole due to the bending of the plastic film and does not need heat-sealing. When heat-sealing and clamping, the cutter 36 will also contact the cushion table 6 to cut the upper plastic film, and at the same time, the plastic film is clamped again by the picking unit 8; after sealing, since the cloth roller is perpendicular to the carrier table 4, by driving the dragging and placing structure 5 close to the cutting unit 3, the carrier rollers 54 on the swing arm 52 are pushed upward from the bottom of the folding arm 22 to push the cloth roller, and the distance between the carrier rollers 54 in the dragging and placing structure 5 above the conveyor belt main body 12 is slowly increased. Then, through mutual cooperation, the cloth roller is tilted and carried between the folding arms 22 on the right side after packaging through the dragging and placing structure 5; S8. Finally, through the flipping and resetting of the folding arms 22, the cloth roller is flipped and packaged and changed from between the folding arms 22 on the left side to between the folding arms 22 on the right side. After the folding arms 22 are reset, the carrier rollers 54 of the dragging and placing structure 5 are relatively separated to open the lower part of the cloth roller, so that the cloth roller falls onto the conveyor belt main body 12 by its own gravity and is transferred through the conveyor belt main body 12.
