Description

Technical Field

[0001] The invention belongs to the technical field of vacuum forming, in particular to an environmentally friendly plastic vacuum forming processing equipment. Background Art

[0002] The blister forming machine is also called the thermoplastic forming machine. The process of this forming equipment mainly uses the vacuum suction force generated by a vacuum pump to heat and soften thermoplastic plastic sheets such as PVC, PET, PETG, APTT, PP, PE, PS, etc. through a mold to form plastic products of various shapes.

[0003] At present, when plastic products are vacuum-formed, it is necessary to manually place a plastic sheet on the upper surface of the mold, and then use a vacuum pump to evacuate the mold cavity. The plastic sheet is deformed into the mold cavity under the vacuum effect and then forms a plastic product with a characteristic shape. However, manually attaching the plastic sheet to the upper surface of the mold is labor-intensive, resulting in a relatively low vacuum forming efficiency. On the other hand, when the vacuum pump is evacuated, the plastic sheet cannot be in close contact with the upper surface of the mold, resulting in external air entering the mold cavity through the gap between the plastic sheet and the mold, making it impossible for the plastic product to deform quickly into the mold cavity, resulting in a relatively low vacuum forming efficiency of the plastic product. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide an environmentally friendly plastic vacuum forming processing equipment.

[0010] The unwinding assembly is arranged on the upper part of the support platform and is used to unwind the plastic layer.

[0011] The second driving assembly is arranged at the side of the forming block. When the forming block slides away from the position directly below the sealing plate, the second driving assembly is used to drive the unwinding assembly to rotate so as to pull the plastic layer to the position directly below the sealing plate.

The two groups of reels are rotatably matched with the bracket plate, and the bracket plate is fixedly arranged on the upper part of the support platform. The two ends of the plastic layer are respectively wound around the outside of the two groups of reels.

[0018] The second driving assembly includes helical teeth, an elastic member and a first gear.

[0019] The first gear is fixedly arranged at one of the ends of the reels, and the bevel teeth are provided with several groups, and the several bevel teeth are hingedly arranged on the side of the support rod away from the several straight teeth. One side of each group of bevel teeth is connected to the support rod through a group of elastic members, and the several bevel teeth can be unidirectionally meshed with the first gear.

[0020] As a further improvement of the present invention: the cutter is annular in structure, and a cutting groove having the same shape as the cutter is formed on the upper edge of the forming block.

[0021] As a further improvement of the present invention: the width of the plastic layer is greater than the width of the forming block and the sealing plate.

Then, the first driving component is used to drive the sealing plate to move downward. At this time, the third driving component drives the forming block to slide to a position directly below the sealing plate. The plastic layer is located between the sealing plate and the forming block. When the sealing plate moves downward, the cutter at the bottom of the sealing plate cuts the plastic layer to cut a sheet-like plastic body in the middle of the plastic layer. Then, the sealing plate presses the sheet-like plastic body against the upper part of the forming block and seals the forming cavity. Then, the vacuum pump is started to evacuate the inside of the forming cavity through the negative pressure hole. The sheet-like plastic body is deformed into the inside of the forming cavity under the vacuum effect and fits tightly against the inner wall of the forming cavity, thereby completing a blister processing. Then, the first driving component drives The sealing plate moves up, and the third driving assembly drives the forming block to slide in the opposite direction, so that the forming block slides away from the position directly below the sealing plate, and at the same time, the second driving assembly drives the unwinding assembly to rotate, thereby pulling the plastic layer to move, so that the subsequent uncut plastic layer moves to the position directly below the sealing plate, thereby realizing automatic feeding of the plastic layer.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] See also Figure 1 , Figure 2 as well as Figure 3The present embodiment provides an environmentally friendly plastic blister processing and forming device, including a support table 10, a forming block 20, a winding assembly 30, a plastic layer 40, a sealing plate 50, a first driving assembly 60, a second driving assembly 70 and a third driving assembly 80. The forming block 20 is slidably arranged on the upper part of the support table 10, and a forming cavity 201 is opened on the upper part of the forming block 20. A vacuum pump (not shown in the figure) is arranged inside the forming block 20. A negative pressure hole 202 connected to the vacuum pump is arranged at the bottom of the forming cavity 201. The sealing plate 50 is arranged above the forming block 20 and is controlled to move up and down by the first driving assembly 60. A cutter 501 is arranged at the bottom of the sealing plate 50. The third driving assembly 80 The third driving assembly 80 is arranged on the side of the forming block 20. When the sealing plate 50 moves downward, the third driving assembly 80 is used to drive the forming block 20 to slide to the position directly below the sealing plate 50. When the sealing plate 50 moves upward, the third driving assembly 80 is used to drive the forming block 20 to slide away from the position directly below the sealing plate 50. The winding assembly 30 is arranged on the upper part of the support platform 10, and is used to wind and unwind the plastic layer 40. The second driving assembly 70 is arranged on the side of the forming block 20. When the forming block 20 slides away from the position directly below the sealing plate 50, the second driving assembly 70 is used to drive the winding assembly 30 to rotate so as to pull the plastic layer 40 to the position directly below the sealing plate 50.

[0034] Initially, the forming block 20 is located at a position obliquely below the sealing plate 50 and is in an up-and-down misalignment state with the sealing plate 50. During the blister processing, the unwinding assembly 30 can be used to unwind the plastic layer 40 so that the plastic layer 40 is located directly below the sealing plate 50. Subsequently, the first driving assembly 60 is used to drive the sealing plate 50 to move downward. At this time, the third driving assembly 80 drives the forming block 20 to slide to a position directly below the sealing plate 50. The plastic layer 40 is located between the sealing plate 50 and the forming block 20. When the sealing plate 50 moves downward, the cutter 501 at the bottom of the sealing plate 50 cuts the plastic layer 40 to cut out a sheet-like plastic body in the middle of the plastic layer 40. Subsequently, the sealing plate 50 presses the sheet-like plastic body against the upper part of the forming block 20 and seals the forming cavity 201. Subsequently, the vacuum pump is started to evacuate the inside of the forming cavity 201 through the negative pressure hole 202. The sheet-like plastic body is deformed into the inside of the forming cavity 201 by the vacuuming effect and tightly fits against the inner wall of the forming cavity 201. The plastic layer 40 is tightly fitted, thereby completing a vacuum forming process. Subsequently, the first driving component 60 drives the sealing plate 50 to move upward. At this time, the third driving component 80 drives the forming block 20 to slide in the opposite direction, so that the forming block 20 slides away from the position directly below the sealing plate 50. At the same time, the second driving component 70 drives the winding and unwinding component 30 to rotate, thereby pulling the plastic layer 40 to move, so that the subsequent uncut plastic layer 40 moves to the position directly below the sealing plate 50, thereby realizing automatic feeding of the plastic layer 40. When the forming block 20 slides away from the position directly below the sealing plate 50, the staff can take out the plastic product formed in the molding cavity 201, and then the first driving component 60 drives the sealing plate 50 to move downward again, and the third driving component 80 drives the forming block 20 to slide again to the position directly below the sealing plate 50, the cutter 501 cuts the plastic layer 40 again, and the vacuum pump vacuumizes the molding cavity 201 again to realize secondary vacuum forming process. Such a reciprocating cycle can realize continuous vacuum forming process of the plastic layer 40.

[0035] See also Figure 1 and Figure 4In one embodiment, a plurality of vertical rods 102 are fixedly provided on the upper edge of the support platform 10, a top plate 103 is fixedly provided on the upper ends of the vertical rods 102, the first driving component 60 is a hydraulic cylinder, the hydraulic cylinder is installed at the bottom of the top plate 103, the sealing plate 50 is arranged at the output end of the hydraulic cylinder, and a support rod 502 is fixedly provided on the side wall of the sealing plate 50, the third driving component 80 includes a spur gear 801, a second gear 802, a third gear 803, a rack 804 and a rotating shaft 805, the support platform A support base 101 is fixedly set on the upper part of 10, the rotating shaft 805 passes through the supporting base 101 and rotates with the supporting base 101, the second gear 802 and the third gear 803 are fixedly set at both ends of the rotating shaft 805, the rack 804 is fixedly set on the side wall of the forming block 20 and meshes with the second gear 802, and the spur teeth 801 are provided with a plurality of groups, a plurality of the spur teeth 801 are fixedly set on one side of the support rod 502, and a plurality of the spur teeth 801 are meshed with the third gear 803.

[0036] The hydraulic cylinder is extended, thereby driving the sealing plate 50 to move downward. When the sealing plate 50 moves downward, it drives the support rod 502 to move downward. Through the meshing action of a plurality of spur teeth 801 and the third gear 803, the rotating shaft 805 is driven to rotate. The rotating shaft 805 drives the second gear 802 to rotate. Through the meshing action of the second gear 802 and the rack 804, the forming block 20 is driven to slide along the upper part of the support platform 10. When the forming block 20 slides to the position directly below the sealing plate 50, the plurality of spur teeth 801 are disengaged from the third gear 803, and the forming block 20 remains stationary. The cutter 501 at the bottom of the sealing plate 50 acts on the plastic layer 40 to cut out a sheet of plastic body, and the sealing plate 50 presses the sheet of plastic body against the forming block 20. At the top, the molding cavity 201 is sealed, and then the vacuum pump is started to evacuate the inside of the molding cavity 201. The sheet plastic body is deformed toward the inside of the molding cavity 201 by the vacuum negative pressure and adheres tightly to the inner wall of the molding cavity 201 to achieve one-time vacuum forming processing. Then the hydraulic cylinder retracts to drive the sealing plate 50 to move up, and the sealing plate 50 drives the support rod 502 to move up, and through the reverse meshing of a number of straight teeth 801 and the third gear 803, the rotating shaft 805 and the second gear 802 are driven to rotate in the opposite direction, and through the reverse meshing of the second gear 802 and the rack 804, the molding block 20 is driven to slide away from the position directly below the sealing plate 50, so that the staff can pick up the plastic products inside the molding cavity 201.

[0037] See also Figure 1 and Figure 4In one embodiment, the unwinding assembly 30 includes two groups of reels 302, which are distributed on both sides below the sealing plate 50, and the two groups of reels 302 are supported by a bracket plate 301. The two groups of reels 302 are rotatably matched with the bracket plate 301, and the bracket plate 301 is fixedly arranged on the upper part of the support platform 10. The two ends of the plastic layer 40 are respectively wound around the outside of the two groups of reels 302. The second driving assembly 70 includes a bevel gear 701, an elastic member 702 and a first gear 703. The first gear 703 is fixedly arranged at the end of one group of the reels 302. The bevel gear 701 is provided with a plurality of groups, and the plurality of bevel teeth 701 are hingedly arranged on a side of the support rod 502 away from the plurality of straight teeth 801. One side of each group of bevel teeth 701 is connected to the support rod 502 through a group of elastic members 702, and the plurality of bevel teeth 701 can be unidirectionally meshed with the first gear 703.

[0038] When the sealing plate 50 drives the support rod 502 to move downward, the plurality of bevel teeth 701 act on the first gear 703 in turn and deflect in the opposite direction of the support rod 502 in turn. The plurality of bevel teeth 701 cannot mesh with the first gear 703, and thus cannot drive the first gear 703 and the corresponding reel 302 to rotate. The plastic layer 40 remains stationary. When the cutter 501 cuts out a sheet of plastic from the middle of the plastic layer 40, and the vacuum pump absorbs the sheet of plastic into the molding cavity 201 and completes a vacuum molding process, the sealing plate 50 drives the support rod 502 to move downward. The support rod 502 moves upward, and at this time, the plurality of bevel teeth 701 can mesh with the first gear 703, thereby driving the corresponding reel 302 to rotate. When the reel 302 rotates, it can pull the plastic layer 40 to move, and the plastic layer 40 is unwound from another set of reels 302. When the plastic layer 40 moves, its uncut part can be moved to the position directly below the sealing plate 50, so that when the sealing plate 50 moves downward subsequently, the cutter 501 can continue to cut the sheet plastic body in the middle part of the plastic layer 40, thereby achieving the purpose of continuous blister processing.

[0039] In one embodiment, the elastic member 702 may be a spring or a metal spring, which is not limited here.

[0040] See also Figure 2 and Figure 3 In one embodiment, the cutter 501 is annular in structure, and a cutting groove 203 having the same shape as the cutter 501 is formed on the upper edge of the forming block 20 .

[0041] When the sealing plate 50 drives the cutter 501 to move downward and the cutter 501 cuts out a sheet of plastic from the middle part of the plastic layer 40, the cutter 501 can be inserted into the cutting groove 203 to facilitate cutting of the plastic layer 40. When the cutter 501 is inserted into the cutting groove 203, the sealing plate 50 can press the cut sheet of plastic against the upper edge of the forming block 20, so that the sheet of plastic can be better deformed into the forming cavity 201 under the action of negative pressure, thereby improving the blister processing effect.

[0042] In one embodiment, the width of the plastic layer 40 is greater than the width of the forming block 20 and the sealing plate 50, so that when the cutter 501 acts on the plastic layer 40, it only cuts out a sheet of plastic in the middle of the plastic layer 40, thereby avoiding the entire plastic layer 40 from being directly cut off, thereby ensuring that the reel 302 can smoothly pull and reel the cut plastic layer 40, and at the same time pull the subsequent plastic layer 40 to be directly below the sealing plate 50.

[0043] See also Figure 1 and Figure 3 In one embodiment, a slide rail 104 is fixedly provided on the upper portion of the support platform 10 , and a slide rail groove 204 adapted to the slide rail 104 is opened at the bottom of the forming block 20 .

[0044] The bottom of the forming block 20 is slidably matched with the slide rail 104 through the slide rail groove 204 , so that the forming block 20 can slide smoothly along the upper part of the support platform 10 .

[0045] In the embodiment of the present invention, initially, the forming block 20 is located at a position obliquely below the sealing plate 50 and is in an up-down misalignment state with the sealing plate 50. When the blister processing is performed, the unwinding assembly 30 can be used to unwind the plastic layer 40 so that the plastic layer 40 is located directly below the sealing plate 50. Then, the first driving assembly 60 is used to drive the sealing plate 50 to move downward. At this time, the third driving assembly 80 drives the forming block 20 to slide to a position directly below the sealing plate 50. The plastic layer 40 is located between the sealing plate 50 and the forming block 20. When the sealing plate 50 moves downward, the cutter 501 at the bottom of the sealing plate 50 cuts the plastic layer 40 to cut out a sheet of plastic body in the middle of the plastic layer 40. Then, the sealing plate 50 presses the sheet of plastic body against the upper part of the forming block 20 and seals the forming cavity 201. Then, the vacuum pump is started to evacuate the inside of the forming cavity 201 through the negative pressure hole 202. The sheet of plastic body is deformed into the inside of the forming cavity 201 by the vacuum effect and fits tightly to the inner wall of the forming cavity 201, thereby completing a vacuum forming process. Then, the first drive The moving assembly 60 drives the sealing plate 50 to move upward. At this time, the third driving assembly 80 drives the forming block 20 to slide in the opposite direction, so that the forming block 20 slides away from the position directly below the sealing plate 50. At the same time, the second driving assembly 70 drives the winding assembly 30 to rotate, thereby pulling the plastic layer 40 to move, so that the subsequent uncut plastic layer 40 moves to the position directly below the sealing plate 50, thereby realizing automatic feeding of the plastic layer 40. When the forming block 20 slides away from the position directly below the sealing plate 50, the staff can take out the plastic product formed in the forming cavity 201, and then the first driving assembly 60 drives the sealing plate 50 to move downward again, and the third driving assembly 80 drives the forming block 20 to slide again to the position directly below the sealing plate 50, the cutter 501 cuts the plastic layer 40 again, and the vacuum pump evacuates the forming cavity 201 again to realize secondary vacuum forming processing. Such a reciprocating cycle can realize continuous vacuum forming processing of the plastic layer 40. Compared with the prior art, it can realize automatic and continuous vacuum forming of plastic products, and has the advantages of high processing efficiency and good forming effect of plastic products.

[0046] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
