Description

Technical Field

[0001] The invention relates to the technical field of plastic film production, in particular to a particle raw material packaging machine for plastic film production. Background Art

[0002] Plastic film, also known as heat-mounted film, card protection film, laminating film or over-laminated film, is a good helper for protecting documents and photos. It generally includes a PET film layer and an EVA resin layer that are bonded to each other. The specific processing process is to coat the molten EVA resin on the surface of the PET film, and then dry the EVA resin melt glue into sheets to compound it on the PET film layer. Then, by cutting and slicing the scraps, the plastic film is cut into the target size and finally packaged. The molten EVA resin is usually formed by heating the EVA masterbatch particles. Before the molten material is processed, in order to improve the performance of the EVA resin, it is usually necessary to add stabilizer, antioxidant and other additive particles to the EVA masterbatch particles. At present, the raw materials for the production of plastic films are usually selected by weighing to quantitatively select EVA masterbatch particles and a variety of additive granular raw materials. However, since the production of plastic films is a continuous batch production, the corresponding raw materials need to be continuously prepared during the continuous production process, resulting in the production process of plastic films being too cumbersome and the production efficiency being low. Therefore, it is necessary to use material dividing equipment to quantitatively package a variety of different granular raw materials.

[0003] For example, the utility model patent document with patent publication number CN215196786U discloses a physical mixed water-soluble fertilizer production device. The specific scheme is to use multiple batching bins to carry different fertilizers, use electromagnetic valves to control the output of the batching bins, and set a weight loss scale under the batching bin. After the electromagnetic valve is opened, the fertilizer mixing and packaging process can be controlled by the weight loss scale and the electromagnetic valve. When this production device is applied to the packaging production of plastic film granular raw materials, the production device can classify and package different granular raw materials one by one according to the style of the plastic film, but it is impossible to simultaneously hold and package multiple granular raw materials according to the type of plastic film, and the production efficiency needs to be improved. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing particle raw material classification device cannot perform synchronous packaging on a variety of particle raw materials required for the production of plastic packaging films.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a granular raw material packaging machine for plastic film production, including a discharging device, a valve body device installed on the discharging device, a receiving device arranged under the valve body device, and a conversion device that drives the receiving device to move, the discharging device includes a plurality of silos and a temporary storage box installed below the silos, the valve body device includes a valve pipe installed on the temporary storage box and corresponding to the silo, and a rotatable bent plate rotatably installed in the valve pipe, a permanent magnet is installed on the rotatable bent plate, and the permanent magnet controls the rotatable bent plate to seal the valve pipe after being attached, The receiving device includes a support plate that is supported on the rotating bent plate, a sleeve ring fixedly installed under the valve plate, and a pressure ring installed on the support plate. A support column is installed on the side wall of the valve tube. A push groove for accommodating the support column is opened on the support plate. The groove wall of the push groove away from the rotating bent plate is inclined. The push groove and the support column support each other. When the support plate moves in the valve tube, it is pushed by the support column to move toward the sleeve ring. The rotating bent plate is pushed by the support plate to rotate in the valve tube. The rotating device includes a pushing cylinder, which can push the support plate to move in the valve tube.

[0006] Furthermore, the end of the abutting plate that abuts against the rotating bent plate is in a sloped state, and the sloped surface of the abutting plate can push the rotating bent plate.

[0007] Furthermore, the receiving device also includes a travel frame sleeved on the end of the abutment plate, the travel frame is arranged on the end of the abutment plate away from the rotating bent plate, and the collar is fixedly mounted on the inner wall of the travel frame.

[0008] Furthermore, the pushing cylinder is fixedly connected to the travel frame, a travel groove is opened on the side wall of the travel frame, a travel shaft is fixedly inserted in the abutment plate, and both ends of the travel shaft can be slidably inserted into the travel groove.

[0009] Furthermore, a connecting rod is fixedly mounted on the collar, and the collar is fixedly mounted on the inner wall of the travel frame through the connecting rod.

[0010] Furthermore, a push rod is fixedly mounted on the pressure ring, and the fixed rod is fixedly connected to the abutment plate.

[0011] Furthermore, the rotating device also includes a push plate installed on the travel frame, the push plate is connected to each of the travel frames, and the pushing cylinder is fixedly connected to the push plate.

[0012] Furthermore, the rotating device also includes a rotating frame installed on the pushing cylinder, and the rotating frame includes a rotating plate fixedly installed on the cylinder body of the pushing cylinder, a rotating rod fixedly connected to the rotating plate, and a rotating cylinder sleeved on the rotating rod.

[0013] Furthermore, the valve body device also includes a rotating shaft fixedly installed in the valve tube, a rotating block is fixedly installed in the corner of the rotating bent plate, and the rotating bent plate is rotatably installed on the rotating shaft through the rotating block.

[0014] Furthermore, a partition is provided in the temporary storage box corresponding to the silo, the partition separates the cavity of the temporary storage box corresponding to the silo, and the valve pipe is connected to each cavity of the temporary storage box corresponding to the silo.

[0015] The beneficial effect of the present invention is that a plastic sealing bag for containing raw material particles is sleeved on the sleeve ring, and the edge of the plastic sealing bag can be folded along the sleeve ring to be between the sleeve ring and the pressure ring. When the push plate moves in the valve tube, the pressure ring is pressed onto the sleeve ring to clamp the plastic sealing bag. At the same time, due to the push of the push plate on the rotating bent plate, the magnetic attraction between the two rotating bent plates is released, and the internal cavity of the valve tube opens. That is, while the plastic sealing bag is fixed under the valve tube, the channel for conveying raw material particles in the valve tube is opened, and the raw material particles can fall from the valve tube into the plastic sealing bag until the raw material particles in the plastic sealing bag reach a specified number. Since the plastic sealing bag corresponds to the valve tube and the silo arrangement, multiple raw material particles can be packaged simultaneously, thereby simplifying the sorting of raw material particles used for the plastic sealing film.

DETAILED DESCRIPTION

[0023] 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 with 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 are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0024] like Figures 1 to 5 As shown, the present invention provides a raw material particle packaging machine 100 for plastic film production, including a discharging device 10, a valve body device 20 installed on the discharging device 10, a receiving device 30 arranged below the valve body device 20, and a conversion device 40 for driving the receiving device 30 to move.

[0025] like Figure 1 and Figure 2 As shown, the discharging device 10 includes a plurality of silos 110 , a discharging pipe 120 installed below the silos 110 , and a temporary storage box 130 installed at the end of the discharging pipe 120 .

[0026] The silo 110 is used to carry raw material particles of different components, such as EVA resin masterbatch particles and various additive particles, which can be added by the user according to the processing needs of the plastic film. Multiple silos 110 are arranged in parallel, and the silos 110 are all arranged in a bucket shape. A transition silo 111 is installed at the outlet of the silo 110, and the transition silo 111 is connected to the silo 110. The discharge pipe 120 is connected to the transition bin 111, and the raw material particles cleaned in the transition bin 111 are discharged through the discharge pipe 120. The temporary storage box 130 is installed on the end of the discharge pipe 120 away from the transition bin 111. The raw material particles can be discharged into the temporary storage box 130 through the discharge pipe 120. The raw material particles can be stored in the temporary storage box 130 in a classified manner. A partition 131 is provided in the temporary storage box 130 corresponding to the silo 110. The partition 131 divides the cavity of the temporary storage box 130 into multiple parts. The cavity of the temporary storage box 130 is provided corresponding to the discharge pipe 120, and a square discharge port 132 is opened on the side wall of the temporary storage box 130 away from the discharge pipe 120.

[0027] like Figure 3 As shown, the valve body device 20 includes a valve tube 210 fixedly mounted on the discharge port 132 , a rotating shaft 220 fixedly mounted in the valve tube 210 , and a rotating bent plate 230 rotatably mounted on the rotating shaft 220 .

[0028] The valve tube 210 is provided with a cover for the discharge port 132, and the shape of the valve tube 210 corresponds to the shape of the discharge port 132. The rotating shaft 220 is fixedly inserted into the side wall of the valve tube 210, and the rotating shaft 220 is arranged in parallel in the valve tube 210. The rotating bent plate 230 is a vertical plate structure, and a rotating block 231 is fixedly installed in the bending corner of the rotating bent plate 230. The rotating block 231 is rotatably sleeved on the rotating shaft 220. There are at least two rotating bent plates 230, and one end of the two rotating bent plates 230 is abutted against the side wall of the valve tube 210, and the other ends of the two rotating bent plates 230 are fitted together. When the rotating bent plate 230 rotates in the valve tube 210, a gap for material falling can be generated between the two rotating bent plates 230. A permanent magnet (not shown) is disposed in the rotating bent plate 230. The permanent magnet is disposed on the sides of the two rotating bent plates 230 that are in contact with each other. Under the magnetic attraction of the permanent magnet, the rotating bent plate 230 is in a closed and fitted state in the valve tube 210. Under the sealing of the rotating bent plate 230, the internal cavity of the valve tube 210 is closed.

[0029] like Figures 3 to 5 As shown, the receiving device 30 includes a support plate 310 that is supported on the rotating bent plate 230, a travel frame 320 sleeved on the end of the support plate 310, a sleeve ring 330 installed in the travel frame 320, and a pressure ring 340 installed on the support plate 310.

[0030] A resist column 211 pointing to the rotating shaft 220 is fixedly installed on the valve tube 210, and the end of the resist plate 310 that resists the rotating bent plate 230 is in a slope structure. The slope surface of the resist plate 310 is set in the direction of the rotating shaft 220, and the end cross-section where the slope surface of the resist plate 310 is located gradually increases in the direction away from the discharge port 132. Specifically, when the resist plate 310 moves toward the rotating bent plate 320, the slope surface of the resist plate 310 can push the rotating bent plate 320, and the end of the resist plate 310 extends between the rotating bent plate 320 and the valve tube 210. A pushing groove 311 is provided on the side of the push plate 310 which is away from the slope surface. The pushing groove 311 can accommodate the push column 211. The groove wall of the push groove 311 away from the discharge port 132 is inclined. Specifically, the groove wall of the inclined pushing groove 311 is arranged toward the push column 211. The cross-section of the inclined pushing groove 311 gradually decreases in the direction away from the discharge port 132. When the push plate 310 moves in the valve tube 210, the push column 211 can push the groove wall of the pushing groove 311. Under the obstruction of the push column 211, the push plate 310 can move in the valve tube 210, thereby expanding the pushing stroke of the push plate 310 on the rotating bent plate 230.

[0031] The travel frame 320 is sleeved on the end of the anti-plate 310, and a travel groove 321 is opened on the side wall of the travel frame 320. A travel shaft 312 is fixedly inserted in the end of the anti-plate 310, and both ends of the travel shaft 312 can be slidably inserted into the travel groove 321. Under the restriction of the travel groove 321 on the travel shaft 312, the sliding stroke of the anti-plate 310 in the valve tube 210 can be limited, thereby preventing the anti-plate 310 from excessively moving in the valve tube 210.

[0032] The collar 330 is arranged corresponding to the blanking gap between the rotating bent plates 320, a connecting rod 331 is fixedly mounted on the collar 330, both ends of the connecting rod 331 are fixedly mounted on the side walls of the travel frame 320, the position of the collar 330 in the travel frame 320 is limited by the fixed connection of the connecting rod 331 on the travel frame 320, a pressing ring 340 is arranged around the outside of the collar 330, a pushing rod 341 is fixedly mounted on the pressing ring 340, the pushing rod 341 is also fixedly connected to the abutment plate 310, when the abutment plate 310 moves in the valve tube 210, the pressing ring 340 can be pushed to move toward the collar 330 until the pressing ring 340 is pressed tightly against the collar 330. A plastic bag (not shown) for carrying raw material particles is stored in the ring 330. The bag mouth of the plastic bag is turned over the ring 330 and folded into the pressure ring 340. The pressure ring 340 is pressed onto the ring 330 by the push of the abutment plate 310. The edge of the plastic bag can be fixed under the rotating bent plate 320 under the squeezing of the pressure ring 340 and the ring 330. After the blanking gap between the two rotating bent plates 320 is opened, the raw material particles can fall into the plastic bag.

[0033] like Figure 1 and Figure 2As shown, the rotating device 40 includes a push plate 410 fixedly mounted on the travel frame 320 , a pushing cylinder 420 connected to the push plate 410 , and a rotating frame 430 mounted on the pushing cylinder 420 .

[0034] The push plate 410 is arranged outside the travel frame 320, the piston rod of the push cylinder 420 is fixedly connected to the push plate 420, and the rotating frame 430 includes a rotating plate 431 fixedly mounted on the cylinder body of the push cylinder 420, a rotating rod 432 fixedly connected to the rotating plate 431, and a rotating cylinder 433 sleeved on the rotating rod 432. The travel frame 320 is provided with a plurality of travel frames 320 corresponding to the silo 110, the push plate 410 is fixedly connected to each travel frame 320, the piston rod of the push cylinder 420 is fixedly connected to the push plate 410, the rotating plate 431 is fixedly connected to the cylinder body of each push cylinder 420, the rotating rod 432 is arranged perpendicular to the push cylinder 420, and the output shaft of the rotating cylinder 433 is fixedly sleeved on the rotating rod 432. Both ends of the rotating rod 432 are connected to the rotating plate 431, and the rotating angle of the rotating cylinder 433 is preferably 180 degrees. When the rotating cylinder 433 is started, the empty plastic packaging bag can be transported to the bottom of the valve tube 210.

[0035] When the above-mentioned raw material particle packaging machine 100 for plastic film production is in use, the plastic packaging bags are first inserted into the ring 330, and each plastic packaging bag is transferred to the bottom of the valve tube 210 by the rotating cylinder 433, and then the pushing cylinder 420 is started. When the piston rod of the pushing cylinder 420 is extended, the travel frame 320 can be pushed by the push plate 410 to move relative to the valve tube 210, and the travel frame 320 drives the push plate 310 to move in the valve tube 210 through the travel shaft 312 until the push plate 310 pushes the rotating bent plate 320 under the push of the push column 211, and the rotating bent plate 320 can rotate in the valve tube 210. At the same time, the push plate 310 drives the pressure ring 340 to move toward the ring 330 in the valve tube 210, and the pressure ring 340 presses and fixes the plastic packaging bags on the ring 330, and the raw material particles in the temporary storage box 130 can be transported to the plastic packaging bags in the ring 330. When the raw material particles in the plastic bag are loaded to the specified amount, the push of the cylinder 420 on the travel frame 320 is released. When the bottom plate 310 is pulled out of the valve tube 210, the pressure ring 340 is separated from the sleeve ring 330, and the plastic bag falls from the gap between the pressure ring 340 and the sleeve ring 330. At the same time, the rotating bent plates 320 are attracted by the permanent magnet, and the two rotating bent plates 320 are re-attached to block the valve tube 210. Then, the rotating cylinder 433 is started to transfer the empty plastic bag to the bottom of the valve tube 210.

[0036] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description.
