Description

It includes main packaging materials such as metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, chemical fibers, composite materials, etc., and auxiliary materials such as strapping, decoration, and printing materials. Among them, plastic packaging materials are generally processed by blister forming. The main principle of blister forming is to heat and soften the flat plastic hard sheet, then use vacuum adsorption to the mold surface, and then cool it to form.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0034] Embodiment 1, refer to Figures 1 to 10 As shown, the present invention provides a technical solution: a packaging material surface forming mechanism, comprising a body 1, a feeding plate 2 is fixedly connected to the bottom surface of the body 1, a cutting table 3 is fixedly connected to the left side of the feeding plate 2, the cutting table 3 is lower than the height of the feeding plate 2, and the height difference between the cutting table 3 and the feeding plate 2 is adapted to the thickness of the formed packaging material, a cutting mechanism is arranged on the cutting table 3, a collecting mechanism is arranged for lifting below the cutting table 3, an opening is formed between the left bottom of the body 1 and the feeding plate 2, two opposite feeding mechanisms are arranged on the feeding plate 2, and a heating mechanism, a forming mechanism, a guiding mechanism and a cooling mechanism are arranged in sequence from right to left inside the body 1.

[0035] The above scheme is adopted: a feed roller is arranged on the right side of the machine body 1, and the packaging material is conveyed by the feed roller and heated by the heating mechanism, and then the packaging material is formed by the forming mechanism, and then the packaging material is conveyed downward by the guiding mechanism, and cooled and positioned by the cooling mechanism to ensure the subsequent normal collection. After the packaging material is formed in the machine body 1, it can be conveyed out through the opening between the feeding plate 2 and the machine body 1, and then the two sides of the packaging material are positioned and fed by the two feeding mechanisms to ensure the normal movement of the packaging box of the packaging material to avoid deformation on the feeding plate 2, and the packaging material is also cooled as the feeding mechanism moves to ensure the subsequent collection and stacking. When it reaches the cutting table 3, the packaging box will automatically fall into the cutting groove on the cutting table 3, and then the cutting mechanism is used to cut the packaging box on the packaging material, so that it automatically falls on the collecting mechanism below the cutting table 3, thereby automatically completing the cutting and collection and stacking of the packaging box, without the need for personnel to stack the cut packaging boxes in sequence.

[0036] It is worth noting here that the forming mechanism is in a rotating state inside the machine body 1, which can greatly improve the efficiency of forming the surface of the packaging material, so that the packaging material can be formed while being conveyed, shortening the forming time of the packaging material, improving the forming efficiency of the packaging material, and the device saves more space.

[0037] like Figure 1 to, Figure 2 , Figure 3 and Figure 5As shown, the cutting mechanism includes a bracket 6 and a cutting board 8, a cutting knife is arranged on the bottom surface of the cutting board 8, a first electric push rod 7 is installed on the top of the bracket 6, the telescopic end of the first electric push rod 7 is connected to the cutting board 8, a second electric push rod 9 is installed on the cutting board 8, the telescopic end of the second electric push rod 9 passes through the cutting board 8 and is fixedly connected to the extrusion plate 33.

[0038] The above scheme is adopted: when the formed packaging material is conveyed to the cutting table 3, the packaging box will fall into the cutting groove, and then the cutting plate 8 will be lowered by the operation of the first electric push rod 7 to cut the packaging box on the packaging material, so that the cut packaging box will automatically slide down to the collecting mechanism. When the height of the packaging box on the collecting mechanism is relatively high, the next time the packaging material is cut, the operation of the second electric push rod 9 can be controlled to drive the squeezing plate 33 to descend, and then the squeezing plate 33 squeezes the packaging box, thereby ensuring that more packaging boxes can be stacked.

[0039] like Figures 1 to 4 As shown, the material collecting mechanism includes a base plate 4 and a support plate 5, the two bottom ends of the bracket 6 are fixedly connected to the base plate 4, and the four corners of the base plate 4 are fixedly connected with support columns 11, and the top of each support column 11 is fixedly connected to the bottom surface of the cutting table 3, and the support plate 5 is sleeved on each support column 11. The surface of each support column 11 is sleeved with a first compression spring 12, and the two ends of the first compression spring 12 are respectively fixedly connected to the base plate 4 and the support plate 5, and a first conveyor belt 10 is installed in the middle of the support plate 5. Two opposite tooth plates 13 are fixedly connected to the support plate 5, and two opposite U-shaped guide plates 14 are fixedly connected to the cutting table 3, and the two tooth plates 13 are respectively slidably arranged in the two U-shaped guide plates 14, and a positioning mechanism for limiting the displacement of the tooth plate 13 is arranged on one side of each U-shaped guide plate 14, and a pressing mechanism for driving the two tooth plates 13 to descend is arranged on the cutting plate 8.

[0040] By adopting the above scheme: when the positioning mechanism releases the restricted displacement of the support plate 5, the support plate 5 can be pushed up by the elastic force of the first compression spring 12, so as to facilitate the collection of the packaging boxes cut by the cutting table 3. By setting the first conveyor belt 10, the packaging boxes cut on the cutting table 3 can be collected. When the packaging boxes on the first conveyor belt 10 are stacked too high, the operation of the first conveyor belt 10 can be started, and the stacked packaging boxes at the bottom of the cutting table 3 can be conveyed to the left side, which is convenient for personnel to directly take away for packaging. In addition, the operation of the first conveyor belt 10 will not affect the subsequent stacking. 10 follows the support plate 5 to reset and rise, and can collect the subsequent packaging boxes. Through the setting of the downward pressing mechanism, when the cutting plate 8 is cutting the packaging material on the cutting table 3 downward, the tooth plate 13 will be driven down together through the downward pressing mechanism, so as to avoid the packaging boxes on the first conveyor belt 10 being stacked too high and affecting the subsequent cutting. The descent of the tooth plate 13 is a short distance descent, so it will not affect the normal stacking of the packaging boxes on the first conveyor belt 10, which effectively saves labor and makes the forming of packaging materials more automated. When the cutting plate 8 is rising, it will not drive the downward pressing mechanism to rise the tooth plate 13.

[0041] like Figure 8 and Fig.10 As shown, the positioning mechanism includes a cylinder 47, which is installed on the side of the cutting table 3. The side of the tooth plate 13 is provided with positioning holes 31 arranged at equal distances. A positioning rod 44 is provided through the side of the U-shaped guide plate 14, and one end of the positioning rod 44 is inserted into the corresponding positioning hole 31. A vertical block 43 is fixedly connected to the positioning rod 44, and a second tension spring 42 is fixedly connected to the vertical block 43, and one end of the second tension spring 42 is fixedly connected to the surface of the positioning rod 44. A sliding groove 45 is provided on the side of the positioning rod 44, and a connecting rod 46 is fixedly connected to the telescopic end of the cylinder 47, and the connecting rod 46 is slidably set in the sliding groove 45.

[0042] By adopting the above scheme: through the setting of the positioning mechanism, when the positioning rod 44 is inserted into the corresponding positioning hole 31, it can be ensured that the tooth plate 13 can only descend in the U-shaped guide plate 14 and will not rise, and when the tooth plate 13 descends, it will push the positioning rod 44 to move to the right, so that the vertical block 43 pulls the second tension spring 42 to move, so that the second tension spring 42 is stretched, until the tooth plate 13 stops moving, the positioning rod 44 can be used to automatically position the tooth plate 13 under the elastic force of the second tension spring 42 to prevent it from rising. When it is necessary to release the positioning of the positioning rod 44 and the tooth plate 13, it is only necessary to use the operation of the cylinder 47 to make the connecting rod 46 drive the positioning rod 44 to move to the right, so that the tooth plate 13 moves upward through the support plate 5, and the operation is more convenient and flexible.

[0043] like Figure 2 , Figure 4 , Figure 5 and Fig. 9 As shown, the pressing mechanism includes a top plate 32, a vertical plate 35 and a mounting plate 38. The top plate 32 is fixedly connected to the support plate 5, the vertical plate 35 is fixedly connected to the cutting plate 8, two guide rods 36 are fixedly connected to the vertical plate 35, and the mounting plate 38 is sleeved on the two guide rods 36. Each guide rod 36 is sleeved with a first tension spring 37, and the two ends of the first tension spring 37 are respectively fixedly connected to the mounting plate 38 and the vertical plate 35. An inclined groove 39 is opened on the mounting plate 38, and the top end of the top plate 32 passes through the inclined groove 39 and extends to the top of the mounting plate 38. The bottom end of the mounting plate 38 is hinged with a lower pressing plate 34, and the right side of the bottom of the mounting plate 38 contacts the upper surface of the second compression spring 48. One end of the lower pressing plate 34 is inserted into the tooth plate 13, and the lower pressing plate 34 is fixedly connected with a second compression spring 48, and the top end of the second compression spring 48 is fixedly connected to the bottom surface of the mounting plate 38.

[0044] By adopting the above scheme, through the setting of the downward pressing mechanism, when the cutting plate 8 moves downward to cut the packaging material on the cutting table 3, it will drive the tooth plate 13 to move downward, and further move the support plate 5 and the first conveyor belt 10 downward, so that the packaging box has the effect of automatically adjusting the height stacking, and improves the collection adaptability of the packaging box. In the specific action, by utilizing the descent of the cutting plate 8, the top end of the top plate 32 will contact the inner wall of the inclined groove 39, so that the mounting plate 38 will be squeezed and moved in the direction of the tooth plate 13, and slide on the two guide rods 36, and at the same time, it will also pull the first tension spring 37 to stretch, and at the same time, one end of the lower pressing plate 34 will also be inserted into the corresponding tooth plate 13, At this time, the cutting plate 8 has not completed cutting the packaging material. When officially cutting, the cutting plate 8 will move downward, so that the lower pressure plate 34 will move the tooth plate 13 downward, thereby realizing the cutting of the packaging material and also realizing the adjustment of the lowering height of the support plate 5. When the cutting plate 8 completes the cutting action, it can be raised by the first electric push rod 7. When the cutting plate 8 is rising, the end of the lower pressure plate 34 inserted into the tooth plate 13 will swing downward, and the other end will be pushed up and squeeze the second compression spring 48, which will not drive the tooth plate 13 to move upward, and the top plate 32 will also be separated from the mounting plate 38, and the mounting plate 38 can be automatically pulled back to its original position under the elastic force of the first tension spring 37.

[0045] like Figure 3 and Figure 6As shown, the forming mechanism includes a forming seat 21, which is rotatably arranged on the inner wall of the body 1, a second motor 19 is installed on the back of the body 1, and the output end of the second motor 19 is connected to the central part of the back of the forming seat 21, a plurality of forming grooves 28 are provided on the surface of the forming seat 21, a plurality of exhaust pipes 22 are embedded in the middle of the forming seat 21, a plurality of groups of exhaust holes 23 are provided inside the forming seat 21, and the exhaust holes 23 are connected with the corresponding exhaust pipes 22 and the forming grooves 28, a suction pipe 41 is provided on the front of the forming seat 21, and the suction pipe 41 is rotatably connected to the front of the body 1, a first wireless solenoid valve 40 is installed at the front end of each exhaust pipe 22 and is connected to the suction pipe 41, the suction pipe 41 is connected to the vacuum pump 20 through a rotating joint, and the vacuum pump 20 is installed on the front of the body 1, the four sides of the forming seat 21 are all arc surfaces, and the four arc surfaces of the forming seat 21 are rotatably connected to the rotating roller 24.

[0046] The above scheme is adopted: when the heated packaging material is conveyed to the forming seat 21, the first wireless solenoid valve 40 at the top is opened, and the other first wireless solenoid valves 40 are closed, and then the uppermost forming groove 28 is vacuumized by the operation of the vacuum pump 20, so that the packaging material above the forming seat 21 is subjected to vacuum forming. After forming, as the forming seat 21 continues to rotate counterclockwise, it will be conveyed downward, and its first wireless solenoid valve 40 will be closed, and the subsequent packaging material will be subjected to vacuum forming through the rotated forming groove 28 in turn, which effectively improves the forming efficiency of the packaging material, and the vacuum pump 20 is fixed on the front side of the machine body 1. Therefore, the vacuum pump 20 will not rotate with the first wireless solenoid valve 40, and the vacuum pump 20 and the suction tube 41 are connected by a rotating joint, thereby ensuring that the vacuum pump 20 can operate normally and that the suction tube 41 rotates with the forming seat 21. When the packaging material is being formed, the first wireless solenoid valve 40 is an existing mature technology and will not be described in detail here. A battery can be installed in the first wireless solenoid valve 40 for power storage. When the top first wireless solenoid valve 40 rotates downward from one side, it is in a closed state, thereby ensuring that only the top first wireless solenoid valve 40 is in an open state, so as to ensure that the top forming groove 28 can normally form the packaging material.

[0047] like Figure 3 As shown, the heating mechanism includes two opposite electric heating plates 29, both of which are installed on the inner wall of the machine body 1, and a plurality of guide rollers 30 are rotatably connected to the lower electric heating plate 29.

[0048] The above solution is adopted: the packaging material entering into the machine body 1 is heated by the electric heating plate 29 , so that it is formed by the forming seat 21 , and the setting of the guide roller 30 can ensure that the packaging material is transported between the two electric heating plates 29 .

[0049] like Figure 3 As shown, the guiding mechanism includes a first guide roller 26 and a second guide roller 25. The second guide roller 25 and the first guide roller 26 are both rotatably connected to the inner wall of the machine body 1, and the distance between the second guide roller 25 and the feeding plate 2 is adapted to the thickness of the formed packaging material.

[0050] By adopting the above scheme: through the setting of the first guide roller 26, the upper surface of the packaging material can be guided to ensure that the packaging material is conveyed downward, and the formed side will be rotated and conveyed on the forming seat 21. Through the setting of the second guide roller 25, it can be ensured that the formed packaging material is conveyed to the left, and the formed side of the packaging material will automatically detach from the forming seat 21, making it easier to demold.

[0051] like Figures 1 to 3 As shown, the cooling mechanism includes an air cooler 49 and a cooling air duct 27. The air cooler 49 is installed on the left side of the body 1, and the cooling air duct 27 is arranged inside the body 1 and located on the left side of the forming seat 21. The air outlet end of the air cooler 49 passes through the body 1 and is connected to the cooling air duct 27.

[0052] The above scheme is adopted: when the formed packaging material is transported downward on the left side of the forming seat 21, the gear 18 is used to blow cold air through the cooling air duct 27 to cool the formed packaging material, which is conducive to the subsequent separation of the packaging material from the forming seat 21.

[0053] like Figures 1 to 3 , Figure 7 As shown, the feeding mechanism includes a mounting seat 15, which is fixedly connected to the feeding plate 2. Two second conveyor belts 16 are installed on the inner side of the mounting seat 15. The transmission shafts of the two second conveyor belts 16 pass through the mounting seat 15 and are fixedly connected with gears 18, and the two gears 18 are meshed with each other. A first motor 17 is installed on the outer side of the mounting seat 15, and the output end of the first motor 17 is connected to the transmission shaft of one of the second conveyor belts 16.

[0054] With the above solution, when the packaging material is conveyed to the left by the second guide roller 25, both sides of the packaging material will be conveyed between the two sets of second conveyor belts 16 respectively, thereby providing a conveying effect for subsequent cutting.

[0055] Embodiment 2, see Figures 11 to 13As shown, the present invention provides another technical solution: a packaging material surface forming mechanism, including a machine body 1, an injection molding upper mold mechanism is arranged on the machine body 1, and an injection molding lower mold mechanism is rotatably arranged inside the machine body 1. By using the cooperation of the injection molding upper mold mechanism and the injection molding lower mold mechanism, the device can perform injection molding on the packaging material, and the injection molding lower mold mechanism is in a rotating state, so after one material is injected, the next material can be injected, and the rotating injection molding lower mold mechanism is also convenient for subsequent cooling and demoulding. The left side of the machine body 1 is provided with A cooling mechanism is provided, and the cooling mechanism is arranged on the left side of the injection lower mold mechanism. With the setting of the cooling mechanism, the packaging material after injection molding can be cooled, which is beneficial to the final demoulding. The bottom surface of the machine body 1 is open, and the material on the injection lower mold mechanism can be dropped downward, so as to be automatically stacked and collected. An observation port is opened on the right side of the machine body 1, and an inspection door is installed on the right side of the machine body 1. The setting of the observation port makes it convenient for the staff to observe the working status inside the machine body 1, and the inspection door also facilitates the maintenance of the structural components inside the machine body 1.

[0056] like Figures 11 to 13 As shown, the injection molding upper mold mechanism includes an extruder 50, a lifting cylinder 51 and an upper mold base 60. The extruder 50 is fixedly connected to the upper surface of the machine body 1. The lifting cylinder 51 is installed on the machine body 1 through a bracket. The telescopic end of the lifting cylinder 51 is fixedly connected with a lifting plate 52. The bottom end of the lifting plate 52 is fixedly connected with a guide rod that penetrates into the machine body 1. The upper mold base 60 is fixedly connected to the bottom end of the guide rod. The operation of the lifting cylinder 51 drives the lifting plate 52 to rise and fall, so that the lifting plate 52 drives the guide rod to lift and lower the upper mold base 60. The bottom of the extruder 50 is connected with an extrusion tube 53, and the bottom end of the extrusion tube 53 slides through the machine body 1 and is connected to the upper mold base 60. When the upper mold base 60 is lifted or lowered, it can drive the extrusion tube 53 to move together, so that the extrusion tube 53 can normally transport the packaging material in the extruder 50 to the bottom of the upper mold base 60.

[0057] like Fig.12 and Fig.13As shown, the injection lower mold mechanism includes a lower mold base 56, a second motor 19 is installed on the back of the machine body 1, and the output end of the second motor 19 is connected to the center of the lower mold base 56, a plurality of injection cavities 61 are provided on the surface of the lower mold base 56, and the injection cavities 61 are adapted to the upper mold base 60, four blowing pipes 58 are embedded in the middle of the lower mold base 56, and a blowing hole 54 connected to the blowing pipe 58 is provided in the injection cavity 61, a rotating drum 57 is rotatably connected to the front of the machine body 1, and a second wireless solenoid valve 59 is installed at the front end of each blowing pipe 58 and is connected to the rotating drum 57, an air compressor 55 is fixedly installed on the front of the machine body 1, and the front end of the rotating drum 57 is connected to the air compressor 55 through a rotary joint, and the above mechanism is coordinated with the injection upper mold mechanism, and the upper mold base 60 is controlled to descend by the lifting cylinder 51, so that the upper mold base 60 can be lowered. The packaging material is molded between the upper mold base 60 and the injection cavity 61. After the material is molded, the upper mold base 60 is controlled to rise by the lifting cylinder 51, and then the second motor 19 is started to drive the lower mold base 56 to rotate counterclockwise, and the rotating drum 57 also rotates together. Since the air compressor 55 and the rotating drum 57 are connected by a rotating joint, the air compressor 55 will not be driven to rotate, so that the injection-molded material rotates counterclockwise to the left side with the lower mold base 56 and is cooled by the cooling mechanism. Then it rotates to the bottom and opens the second wireless solenoid valve 59 at the bottom. Then the air compressor 55 is started to transport high-pressure air through the rotating drum 57 to the corresponding blowing pipe 58, thereby demolding the molding material in the injection cavity 61 at the bottom of the lower mold base 56 and dropping it downward. There is no need for manual demolding by personnel, which improves the efficiency of material molding.

[0058] like Fig.12 As shown, the cooling mechanism includes an air cooler 49 and a cooling air duct 27. The air cooler 49 is installed on the left side of the machine body 1, and the cooling air duct 27 is arranged inside the machine body 1 and on the left side of the lower mold base 56. The air outlet end of the air cooler 49 passes through the machine body 1 and is connected to the cooling air duct 27. Through the arrangement of the above structure, when the material in the injection cavity 61 is completed after the injection molding, as the lower mold base 56 rotates counterclockwise by 90°, the cold air can be transported to the cooling air duct 27 by the air cooler 49, and finally the cold air is discharged through the cooling air duct 27 to cool the injection cavity 61 rotated to the left side, and then the lower mold base 56 is rotated counterclockwise by 90° to demold and discharge the cooled molding material, and the subsequent injection-molded material can also be cooled.

[0059] The working principle and use process of the present invention are as follows: first, the packaging material is conveyed by the feed roller and heated by the heating mechanism, and then the packaging material is formed by the forming mechanism, and then the packaging material is conveyed downward by the guiding mechanism, and cooled and positioned by the cooling mechanism to ensure subsequent normal collection. After the packaging material is formed in the machine body 1, it can be conveyed out through the opening between the feeding plate 2 and the machine body 1, and then the two sides of the packaging material are positioned and fed by the two feeding mechanisms to ensure that the packaging box of the packaging material moves normally and avoids deformation on the feeding plate 2. The packaging material also has a cooling effect as the feeding mechanism moves to ensure subsequent collection and stacking. When the formed packaging material is conveyed to the cutting table 3, the packaging box will fall into the cutting groove, and then the cutting plate 8 will descend to cut the packaging box on the packaging material under the operation of the first electric push rod 7, so that the cut packaging box will be automatically When the cutting plate 8 is lifted up, the end of the lower pressing plate 34 inserted into the tooth plate 13 will swing downward, and the other end will push up and squeeze the second compression spring 48, which will not drive the tooth plate 13 to move upward, and the top plate 32 will also be separated from the mounting plate 38, and the mounting plate 38 will be automatically pulled back to its original position under the elastic tension of the first tension spring 37. When the height of the packaging box on the collecting mechanism is high, the next time the packaging material is cut, the operation of the second electric push rod 9 can be controlled to drive the squeezing plate 33 to descend, so that the squeezing plate 33 squeezes the packaging box, thereby ensuring that more packaging boxes can be stacked, and there is no need for personnel to stack the cut packaging boxes in sequence.
