Description

Technical Field

[0001] This utility model belongs to the field of transparent film packaging technology, and in particular relates to a plastic clay packaging machine. Background Technology

[0002] Packaging machines, also known as transparent film packaging machines, are widely used for three-dimensional skin packaging of cosmetics, pharmaceuticals, food, health products, audio-visual products, stationery, daily necessities, and other products using transparent film. The packaging film is cut to the required length, small boxes are conveyed by a conveyor, and stacked by a cylinder. The film is then wrapped and folded to form a three-dimensional package. For example, Chinese utility model patent CN202121307029.6 discloses a fully automatic three-dimensional wrapping machine with an easy-tear processing component.

[0003] When using the aforementioned patent, products need to be arranged one by one and then transported to the pushing mechanism via a feeding conveyor belt. The pushing mechanism then pushes the products to the easy-tear processing component for film coating. Therefore, when the above packaging machine transports sticky products, the products will stick together, making it impossible for the pushing mechanism to push individual products. In addition, when the pushing mechanism pushes out and resets the product, the sticky product will also be carried out by the pushing mechanism. In summary, the existing packaging machine is not suitable for sticky products, and a packaging machine that can transport and coat sticky products such as modeling clay is needed. Utility Model Content

[0004] The purpose of this invention is to provide a plastic clay packaging machine to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a plastic clay packaging machine, comprising a frame, wherein the frame is provided with a film feeding mechanism, a film covering mechanism, a material pushing mechanism, a material pressing mechanism, a material discharging mechanism, a drive mechanism, and a control mechanism; a material conveying frame is provided on one side of the frame, and a feeding conveyor belt is provided between the material conveying frame and the frame; the feeding conveyor belt is provided with several stops, and a feeding position for placing clay is formed between adjacent stops; the output port of the feeding conveyor belt is correspondingly provided on one side of the material pushing mechanism; the material pressing mechanism includes a pressure plate correspondingly provided below the film covering mechanism and a transmission mechanism for driving the pressure plate to move up and down, and the material pressing mechanism is used to press the clay to be filmed.

[0006] Furthermore, the transmission mechanism includes a cam connected to the output end of the transmission motor and a first crank connecting rod connected to the cam transmission. The first crank connecting rod has a transmission surface for contacting the cam. The end of the first crank connecting rod away from the cam is connected to a push block via a push rod. A guide rail is provided on one side of the push block. A slider that slides with the guide rail is provided on the push block. The pressure plate is fixedly mounted on the upper end of the push block.

[0007] Furthermore, it also includes a connecting plate, on one side of which the drive motor is mounted, and the first crank connecting rod is movably disposed on the connecting plate. The connecting plate has a slot above it for the push block to extend upward.

[0008] Furthermore, the laminating mechanism includes an easy-tear processing component, a film pulling mechanism, and a film cutting mechanism. The easy-tear processing component is used to cut a tear line on the transparent film. The film pulling mechanism is used to flatten the transparent film and provide a continuous driving force for conveying the transparent film. The film cutting mechanism is used to cut the transparent film.

[0009] Furthermore, the pushing mechanism includes a push plate, a transfer slide plate, and a guide slide rail disposed within the frame. The transfer slide plate and the guide slide rail are slidably engaged. The push plate is fixedly mounted on the upper end of the transfer slide plate. A first transmission rod is movably disposed on the transfer slide plate. The end of the first transmission rod away from the transfer slide plate is rotatably disposed on a mounting base within the frame. A second transmission rod is connected to the first transmission rod. The second transmission rod is connected to a second crank connecting rod. The second crank connecting rod is connected to the main motor via a gear transmission mechanism.

[0010] Furthermore, the adapter slide is provided with an auxiliary block, and the auxiliary block has a movable groove. One end of the first transmission rod is slidably disposed in the movable groove through a guide wheel. The frame is also provided with a wire groove for the adapter slide to move.

[0011] Furthermore, the feeding rack has a platform for placing the clay to be processed. The feeding conveyor belt crosses the platform and divides it into two picking areas. The connecting shafts at both ends of the feeding conveyor belt are fixed to the feeding rack and the machine frame, respectively, with one end of the connecting shaft connected to the motor output end.

[0012] Furthermore, the film feeding mechanism includes an upper film unit and a guiding film unit. A transparent film is mounted on the upper film unit, and the guiding film unit is used to transport the transparent film to the coating mechanism.

[0013] Furthermore, the frame is also equipped with a film folding mechanism and a heat sealing mechanism. The film folding mechanism is located downstream of the film coating mechanism. The frame is equipped with a worktable, and the upper surface of the worktable is equipped with two opposing film folding and heat sealing fixing plates. Each of the two film folding and heat sealing fixing plates is fixedly installed with a film folding plate and a heat sealing plate. The heat sealing plate is installed downstream of the film folding plate. The two film folding plates are arranged facing each other, and the two heat sealing plates are arranged facing each other. The film folding mechanism includes two film folding plates, and the heat sealing mechanism includes two heat sealing plates and heat sealing cylinders respectively connected to the two heat sealing plates.

[0014] Furthermore, it also includes a lower ironing and upper folding mechanism, which is located downstream of the film coating mechanism and includes a drive device, a cam rocker transmission structure, an upper folding film assembly, and a lower ironing film assembly.

[0015] Through the above technical solution, compared with the prior art, this utility model has the following beneficial effects: 1. By setting a feeding frame on one side of the frame, the feeding conveyor belt is driven between the frame and the feeding frame. The outlet of the feeding conveyor belt is set relative to the pushing mechanism. At the same time, several stops are set sequentially on the feeding conveyor belt, and a feeding position for placing clay is formed between adjacent stops. The feeding frame can be used to store clay to be coated. The clay is placed into each feeding position by manual sorting, and then transported to the front of the pushing end of the pushing mechanism by the feeding conveyor belt. Since the clay placed on the feeding conveyor belt is separated by stops, the products will not stick together during the conveying process. This allows the pushing mechanism to accurately push individual products, solving the technical problem that existing packaging machines will cause products to stick together when conveying highly viscous products such as clay, resulting in the pushing mechanism being unable to push individual products.

[0016] By setting a pressing mechanism below the laminating mechanism, the pressing mechanism consists of a pressing plate and a transmission mechanism. The transmission mechanism drives the pressing plate to move up and down, while the pressing plate presses the clay. When the clay to be laminated is conveyed to the front of the pushing end of the pushing mechanism via the feeding conveyor belt, the pushing mechanism starts and pushes the clay to be laminated to the bottom of the laminating mechanism through its pushing end. At this time, one side and the bottom of the clay will contact the transparent film. Then, the transmission mechanism of the pressing mechanism starts to work and lifts the pressing plate upward, restricting the clay between the lower heating and upper folding mechanism. Then the pushing mechanism will be pulled out. Since the pressing plate is pressing the clay at this time, the pushing mechanism will not bring out the sticky clay at the same time when it is pulled out. This solves the technical problem in the existing packaging machine that the sticky product will also be brought out by the pushing mechanism when the product is pushed out and reset during the pushing process.

[0017] In summary, this product solves the technical problem that existing packaging machines cannot be used for products with stickiness. Attached Figure Description

[0031] like Figure 1-6 As shown: A plastic clay packaging machine includes a frame 1, on which a film feeding mechanism 2, a film covering mechanism 3, a pushing mechanism 4, a pressing mechanism 5, a discharging mechanism, a driving mechanism, and a control mechanism 6 are provided. A material conveying frame 7 is provided on one side of the frame 1, and a feeding conveyor belt 8 is provided between the material conveying frame 7 and the frame 1. The feeding conveyor belt 8 is provided with a plurality of stops 9, and a feeding position 10 for placing clay is formed between adjacent stops 9. The output port of the feeding conveyor belt 8 is correspondingly provided on one side of the pushing mechanism 4. The pressing mechanism 5 includes a pressing plate 501 correspondingly provided below the film covering mechanism 3 and a transmission mechanism for driving the pressing plate 501 to move up and down. The pressing mechanism 5 is used to press the clay to be filmed.

[0032] In addition, this product can also be used for packaging square modeling clay, polymer clay, kneadable erasers, cylindrical erasers, and hexagonal erasers.

[0033] In this embodiment, the driving mechanism includes a drive motor, which controls the film feeding mechanism 2, the film covering mechanism 3, the material pushing mechanism 4, the material pressing mechanism 5, and the material discharging mechanism to move. The control mechanism 6 is equipped with a PLC control chip to control each component. The feeding conveyor belt 8 is powered by the motor. Several stops 9 are fixedly installed in the same direction of the feeding conveyor belt 8. The feeding positions 10 separated by adjacent stops can be adjusted according to different sizes of clay.

[0034] The discharge mechanism is located downstream of the film cutting mechanism and is used to transport the cut and wrapped products out of the receiving end.

[0035] like Figure 5 As shown: The transmission mechanism includes a cam 502 connected to the output end of the transmission motor and a first crank connecting rod 503 connected to the cam 502. The first crank connecting rod 503 has a transmission surface for contacting the cam 502. The end of the first crank connecting rod 503 away from the cam 502 is connected to a push block 505 via a push rod 504. A guide rail 506 is provided on one side of the push block 505. A slider 507 that slides with the guide rail 506 is provided on the push block 505. A pressure plate 501 is fixedly mounted on the upper end of the push block 505.

[0036] In this embodiment, the convex and planar distribution of the cam 502 contacts the first crank connecting rod 503 to control the swing of the first crank connecting rod 503, thereby causing the pressure plate 501 to move up and down through the cooperation of the push block 505 and the guide rail 506, thus achieving the pressing and releasing of the clay.

[0037] like Figure 5 As shown: It also includes a connecting plate 11, a drive motor is installed on one side of the connecting plate 11, a first crank connecting rod 503 is movably disposed on the connecting plate 11, and a slot for the push block 505 to extend upward is provided on the upper part of the connecting plate 11. In this embodiment, the connecting plate 11 is fixedly mounted on the frame 1. The assembly can be facilitated by installing each pressing mechanism 5 transmission mechanism on the connecting plate 11.

[0038] like Figure 6 As shown: The laminating mechanism 3 includes an easy-tear processing component, a film pulling mechanism, and a film cutting mechanism. The easy-tear processing component is used to cut a tear line on the transparent film. The film pulling mechanism is used to flatten the transparent film and provide a continuous driving force for conveying the transparent film. The film cutting mechanism is used to cut the transparent film. In this embodiment, the easy-tear processing component, the film pulling mechanism, and the film cutting mechanism are all existing technologies and will not be described in detail here.

[0039] like Figure 1-4 As shown: The feeding mechanism 4 includes a push plate 401, a transfer slide plate 402, and a guide slide 403 disposed in the frame 1. The transfer slide plate 402 and the guide slide 403 are slidably engaged. The push plate 401 is fixedly mounted on the upper end of the transfer slide plate 402. A first transmission rod 404 is movably disposed on the transfer slide plate 402. One end of the first transmission rod 404 away from the transfer slide plate 402 is rotatably disposed on the mounting base 405 in the frame 1. A second transmission rod 406 is connected to the first transmission rod 404. The second transmission rod 406 is connected to a second crank connecting rod 407. The second crank connecting rod 407 is connected to the main motor through a gear transmission mechanism.

[0040] like Figure 4 As shown: The adapter slide plate 402 is provided with an auxiliary block 408, and the auxiliary block 408 is provided with a movable groove 409. One end of the first transmission rod 404 is slidably set in the movable groove 409 through a guide wheel. The frame 1 is also provided with a wire groove 410 for the adapter slide plate 402 to move.

[0041] In addition, a test handwheel is provided on one side of the frame 1. The test handwheel is connected to a gear shaft for driving the second crank connecting rod 407 via a chain. Since the end of the second crank connecting rod 407 away from the test handwheel is connected to the second transmission rod 406, the second transmission rod 406 can be controlled to move by means of the test handwheel.

[0042] By setting a pressing mechanism 5 below the film coating mechanism 3, the pressing mechanism 5 consists of a pressing plate 501 and a transmission mechanism. The transmission mechanism is used to drive the pressing plate 501 to move up and down, and the pressing plate 501 is used to press the clay. When the clay to be coated is conveyed to the front of the pushing end of the pushing mechanism 4 through the feeding conveyor belt 8, the pushing mechanism 4 will start and push the clay to be coated to the bottom of the film coating mechanism 3 through its pushing end. At this time, one side and the bottom of the clay will contact the transparent film. Then the transmission mechanism of the pressing mechanism 5 starts to work and lifts the pressing plate 501 upward, restricting the clay between the lower heating and upper folding mechanism. Then the pushing mechanism 5 will be pulled out. Since the pressing plate is pressing the clay at this time, the pushing mechanism 3 will not bring out the sticky clay at the same time when it is pulled out. This solves the technical problem that in the existing packaging machine, the product is sticky and will be brought out by the pushing mechanism at the same time when the product is pushed out and reset.

[0043] like Figure 1-2 As shown: A platform for placing the clay to be processed is formed on the feeding rack 7. The feeding conveyor belt 8 crosses the platform and divides it into two picking areas 701. The connecting shafts at both ends of the feeding conveyor belt 8 are fixed to the feeding rack 7 and the frame 1, respectively. One end of the connecting shaft is connected to the motor output end.

[0044] By setting a feeding frame 2 on one side of the frame 1, the feeding conveyor belt 8 is driven between the frame 1 and the feeding frame 7. The outlet of the feeding conveyor belt 8 is set relative to the pushing mechanism 3. At the same time, several stops 9 are set sequentially on the feeding conveyor belt 7, and a feeding position 10 for placing clay is formed between adjacent stops 9. The feeding frame 7 can be used to store clay to be coated. The clay is placed into each feeding position 10 by manual sorting, and then transported to the front of the pushing end of the pushing mechanism 3 by the feeding conveyor belt 8. Since the clay placed on the feeding conveyor belt 8 is separated by stops 9, the products will not stick together during the conveying process. This allows the pushing mechanism 3 to accurately push individual products, solving the technical problem that existing packaging machines will cause products to stick together when conveying highly viscous products such as clay, resulting in the pushing mechanism being unable to push individual products.

[0045] like Figure 3 As shown: The film feeding mechanism 2 includes an upper film unit 201 and a guiding film unit 202. A transparent film is installed on the upper film unit 201, and the guiding film unit 202 is used to transport the transparent film to the film coating mechanism. In this embodiment, the film feeding mechanism 2 is existing technology and is relatively mature.

[0046] like Figure 1-2 As shown: The frame 1 is also equipped with a folding mechanism 13 and a heat sealing mechanism 12. The folding mechanism 13 is located downstream of the coating mechanism 3. The frame 1 is equipped with a worktable. The upper surface of the worktable is equipped with two opposing folding and heat sealing fixing plates. Folding plates and heat sealing plates are fixedly installed on the two folding and heat sealing fixing plates. The heat sealing plates are installed downstream of the folding plates. The two folding plates are arranged facing each other. The two heat sealing plates are arranged facing each other. The folding mechanism 13 includes two folding plates. The heat sealing mechanism 12 includes two heat sealing plates and heat sealing cylinders connected to the two heat sealing plates respectively. In this embodiment, after the coated material is output from the film cutting mechanism, it will be pushed to the position of the folding plate by the pushing mechanism 3. The folding plate is equipped with two inclined grooves. There are usually extra transparent films on both sides of the coated product. The folding plate can fold these extra transparent films and stick them to the surface of the material. The heat sealing plate is designed to heat-bond the transparent films folded on the sides of the material.

[0047] It also includes a lower ironing and upper folding mechanism, which is located downstream of the film coating mechanism 3 and includes a drive device, a cam rocker transmission structure, an upper folding film assembly and a lower ironing film assembly. In this embodiment, the pressure plate 501 is provided with an opening for the lower ironing film assembly to extend upward. In addition, the lower ironing and upper folding mechanism is existing technology and will not be described in detail here.

[0048] In summary, the above structure and method solve the technical problem that existing packaging machines cannot be used for products with stickiness.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
