[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0040] like Figure 1-Figure 3 As shown, a blister forming mold for a packaging box proposed in one embodiment of the present application includes:

[0041] A support frame 1 is provided with a conveyor belt 2, and a heating plate 3 is installed on the support frame 1 and is located above the conveyor belt 2. It should be noted that the heating plate 3 adopts an existing blowing heater, which can heat and soften the sheet material and press the material toward the mold, so as to facilitate the subsequent blister processing;

[0042] The supporting plates 4 are multiple in number and are detachably connected to the conveyor belt 2 by connecting bolts 401. The connecting bolts 401 are installed at the end of the supporting plate 4 moving toward the conveyor belt 2, so that the supporting plate 4 can automatically flip upward when it moves to the corner of the conveyor belt 2, so that the material bonded thereon can be automatically demoulded without external force, thereby increasing the convenience of the device. A mold base 5 is installed on the supporting plate 4, and a mold block 10 is detachably installed in the mold base 5. The supporting plates 4 are connected end to end to minimize the loss of material as much as possible, and the mold block 10 is detachably installed on the supporting plate 4 through the mold base 5, so that the mold block 10 can be easily replaced, thereby increasing the flexibility and adaptability of the device;

[0043] The connecting pipe 6 is installed at both ends of the mold base 5. The connecting pipe 6 includes a one-way valve pipe 601 connected to the mold base 5. The other end of the one-way valve pipe 601 is connected to a sleeve 602. The sleeve 602 is connected to the mold base 5 through the one-way valve pipe 601. The mold base 5 is used to communicate with the mold block 10, so as to facilitate the suction of air in the mold to complete the vacuum forming operation;

[0044] There are two docking suction pieces 7, which are respectively arranged on both sides of the support frame 1. The two docking suction pieces 7 are respectively arranged opposite to two adjacent support plates 4. The docking suction pieces 7 include mounting plates 701 fixedly connected to both sides of the support frame 1. A movable seat 702 arranged toward the support plate 4 is slidably mounted on the mounting plate 701. A cannula 703 for connecting with the sleeve 602 is connected to the movable seat 702. It should be noted that one end of the cannula 703 is connected to the sleeve 602 and the other end is used to communicate with the existing vacuum equipment to provide power for air extraction;

[0045] When the device is in use, it needs to be used in conjunction with a roll material. Compared with the traditional single sheet material that is vacuum-formed in sequence, the roll material can be fitted with the mold blocks 10 on multiple support plates 4, and then the docking suction piece 7 is replaced to dock with different connecting pipes 6, so that the material can be continuously vacuum-formed without waiting for the material to cool and form, saving cooling and demolding time and improving the flexibility and processing efficiency of the device.

[0046] like Figure 1 As shown, in some embodiments, the support frame 1 includes a base frame 101, and two U-shaped support plates 102 are fixedly connected to the upper end of the base frame 101, and a supporting frame 103 is fixedly connected to the upper side of the two U-shaped support plates 102. The conveyor belt 2 is installed in the supporting frame 103 and moves through the two U-shaped support plates 102. Part of the mold seat 5 slides against the U-shaped support plate 102, and the openings of the two U-shaped support plates 102 are arranged opposite to each other. The inner bottom thereof is used to support the flipped support plate 4 and the mold seat 5 thereon, so that the mold seat 5 and the support plate 4 can still maintain horizontal movement when they are located at the bottom of the conveyor belt 2, so as to facilitate the subsequent circulation movement to proceed smoothly.

[0047] like Figure 3 and Figure 5As shown, in some embodiments, the mold base 5 includes two fixed plates 501 constructed on the support plate 4, and the opposite sides of the two fixed plates 501 are provided with clamps 502 slidably installed on the support plate 4, and the clamps 502 are rotatably installed with adjusting studs 503 that thread through the fixed plates 501, and the one-way valve tube 601 is connected to the fixed plate 501. The clamps 502 are penetrated by a plug-in tube 504 with one end inserted in the one-way valve tube 601 and the other end protruding. The clamps 502 are slidably installed on the support plate 4, and the distance between the two clamps 502 can be changed by rotating the adjusting studs 503, so as to adapt to mold blocks 10 of different sizes, facilitate replacement, and increase the adaptability and flexibility of the device.

[0048] like Figure 5-Figure 7 As shown, in some embodiments, two plug holes 1001 are configured at both ends of the mold block 10, and positioning columns 5021 for plugging with the plug holes 1001 are configured on the opposite sides of the two clamping plates 502. The cooperation between the positioning columns 5021 and the plug holes 1001 can facilitate the installation of the mold block 10, so as to facilitate its positioning and fixing, prevent it from being easily separated, and increase safety. Connecting holes 1002 for plugging with one end of the plug-in tube 504 are configured at both ends of the mold block 10, and a stepped groove 1003 is configured on the top of the mold block 10. A forming groove plate 1004 can be detachably installed in the stepped groove 1003, and the forming groove plate 1004 can be bolted. It can be detachably installed in the stepped groove 1003, which is convenient for replacing the molding groove plate 1004 and increasing the flexibility of the device. It should be noted that a plurality of fine holes for ventilation are constructed in the molding groove plate 1004, and a suction cavity 1005 connected to the connecting hole 1002 is arranged between the molding groove plate 1004 and the stepped groove 1003. When it is necessary to perform vacuum forming operation on the mold block 10, air can be extracted by docking the suction piece 7 with the connecting hole 1002 and the suction cavity 1005, so as to suck the air under the material through the fine holes on the molding groove plate 1004, so that it fits inside the molding groove plate 1004 to ensure the molding of the material.

[0049] like Figure 3-Figure 4As shown, in some embodiments, the one-way valve tube 601 includes a column tube 6011 that is installed on the fixed plate 501, and an arc hole 6012 is configured at one end of the column tube 6011 facing the plug-in tube 504, and a ring block 6013 is configured at the other end of the column tube 6011 and arranged opposite to the arc hole 6012, and a support spring 6014 is fixedly connected to the ring block 6013, and a sealing ball 6015 that abuts against the arc hole 6012 is connected to the other end of the support spring 6014, and the sleeve 602 is fixedly connected to the end of the column tube 6011, and components for connecting the docking suction piece 7 are provided at both ends of the mold block 10 and the mold seat 5, which can be connected through two docking suction pieces. The suction piece 7 performs suction molding operations on different mold blocks 10 respectively, wherein the one-way valve tube 601 serves to block the other end. When air is sucked out at one end, the sealing ball 6015 in the column tube 6011 at this end squeezes the supporting spring 6014 to generate compression, thereby opening the arc hole 6012, while the sealing ball 6015 in the column tube 6011 at the other end squeezes the arc hole 6012 to close it, thereby ensuring the suction effect. The two docking suction pieces 7 are arranged in this way, on the one hand, to improve the processing efficiency, and on the other hand, the first docking suction piece 7 can be used to perform suction molding operations on the material, and the second one can perform secondary suction molding on the material to ensure the quality of the product.

[0050] like Figure 8 As shown, in some embodiments, a horizontal rail 7011 is fixedly connected to the mounting plate 701, and the moving seat 702 is slidably mounted on the horizontal rail 7011, and also includes a driving member 8 for driving the moving seat 702 to move. The driving member 8 includes a screw 801 that is rotatably mounted in the horizontal rail 7011 and threadedly penetrates the moving seat 702, and one end of the screw 801 is fixedly connected to a transmission gear 802. A linkage member 9 for driving the transmission gear 802 to reciprocate is installed on the support frame 1. It should be noted that the length direction of the horizontal rail 7011 is consistent with the moving direction of the conveyor belt 2. It is arranged vertically. When the mold block 10 on the support plate 4 needs to be subjected to the vacuum forming operation, the linkage member 9 will drive the transmission gear 802 to rotate forward. At this time, the screw 801 and the movable seat 702 produce threaded cooperation, which can drive the insertion tube 703 thereon to be inserted into the sleeve 602 for connection. When the transmission gear 802 rotates in the opposite direction, it will drive the insertion tube 703 to be separated from the sleeve 602. The reciprocating cycle can connect the mold blocks 10 on different support plates 4 with the docking suction member 7 under the movement of the conveyor belt 2, thereby realizing continuous vacuum forming operation.

[0051] like Figure 8As shown, in some embodiments, the linkage member 9 includes a transmission rack 901 slidably mounted on the end of the cross rail 7011 and meshing with the transmission gear 802, a toothed disc 902 is rotatably mounted on the side of the support frame 1, a connecting rod 903 is eccentrically hinged on the toothed disc 902, and the other end of the connecting rod 903 is hinged on the transmission rack 901, and the edges on both sides of the support plate 4 are fixedly connected with a driving rack 904 meshing with the toothed disc 902. When the conveyor belt 2 moves, the driving rack 904 on the support plate 4 will be driven to move synchronously, and the driving rack 904 will drive the toothed disc 902 to mesh and rotate in one direction. At this time, the toothed disc 902 and the connecting rod 903 are connected. A reciprocating motion of the crank slider is formed between the rod 903 and the transmission rack 901, so that the transmission rack 901 moves back and forth on the cross rail 7011. It should be noted that when the conveyor belt 2 moves a distance of a support plate 4, the transmission rack 901 will produce a reciprocating motion, thereby driving the transmission gear 802 and the screw 801 to rotate back and forth, that is, the moving seat 702 will drive the insertion tube 703 to be pulled out of the original sleeve 602 and inserted into the next sleeve 602, so as to realize the automatic switching operation of connecting different mold blocks 10, without the need for additional driving force, saving resources, and improving the linkage of the device.

[0052] like Figure 3-Figure 4 As shown, in some embodiments, the sleeve 602 includes a bend pipe 6021 fixedly connected to the end of the one-way valve tube 601, the other end of the bend pipe 6021 is fixedly connected to a telescopic tube 6022 whose length direction is arranged toward the moving direction of the conveyor belt 2, and the other end of the telescopic tube 6022 is connected to a bend pipe 6023 for connecting to the insert tube 703. When the driving rack 904 moves, the insert tube 703 will be driven to move synchronously. At this time, the telescopic tube 6022 can adapt to the displacement to avoid damage caused by obstruction of components and increase the safety of the device.

[0053] like Figure 4 As shown, in some embodiments, the telescopic tube 6022 includes an outer tube 60221, an annular baffle 60222 is constructed at one end of the outer tube 60221, a tension spring 60223 is fixedly connected to the annular baffle 60222, the other end of the tension spring 60223 is fixedly connected to an inner tube 60224 slidably inserted in the outer tube 60221, the outer tube 60221 is connected to the bend tube 1 6021, the inner tube 60224 is connected to the bend tube 2 6023, and a tension spring 60223 is arranged between the inner tube 60224 and the outer tube 60221, so that the inner tube 60224 can be automatically reset when the inner tube 60224 is extended by the insertion tube 703, so as to facilitate the smooth insertion of the subsequent insertion tube 703 and ensure the subsequent smooth operation of the device.

[0055] S1: First, one end of the roll material needs to be laid on the mold block 10, and the material is heated and softened by the heating plate 3 so that it fits into the forming groove plate 1004 of one of the mold blocks 10;

[0056] S2: The conveyor belt 2 drives the support plate 4 on the upper side to move horizontally. At the same time, the driving rack 904 on the edge of the support plate 4 meshes with the toothed disc 902 for transmission. The toothed disc 902 drives the transmission rack 901 to move through the connecting rod 903. The transmission rack 901 drives the transmission gear 802 and the screw 801 to rotate. The screw 801 and the moving seat 702 are threadedly matched, so that the insertion tube 703 on the moving seat 702 is connected with the sleeve 602;

[0057] S3: The conveyor belt 2 continues to move, and the linkage member 9 cooperates with the driving member 8 to form a reciprocating rotation of the screw 801. A single reciprocating rotation corresponds to a moving distance of a single support plate 4, so that the insertion tube 703 is connected with different sleeves 602 in sequence;

[0058] S4: The sleeves 602 at both ends of the mold block 10 on the support plate 4 are connected to the two docking suction pieces 7 in sequence, the first molding, the second molding, and the separation from the docking suction pieces 7 to continue moving for cooling;
