Description

Technical Field

[0001] The present invention relates to the technical field of plastic processing, and more specifically to processing equipment for high-temperature resistant plastic containers. Background Art

[0002] Processing equipment for high-temperature resistant plastic containers refers to mechanical equipment specifically used for producing high-temperature resistant plastic containers. These devices can process plastic raw materials under high-temperature conditions to form plastic containers with high-temperature resistance characteristics. Processing equipment for high-temperature resistant plastic containers is widely used in fields such as food, medicine, and chemical industry.

[0003] During the use of existing processing equipment, due to different model specifications requirements for high-temperature resistant plastic containers in various fields, when processing high-temperature resistant plastic containers of different sizes, corresponding die heads and blow molding dies need to be replaced. In traditional extrusion equipment, the die head is directly installed on the discharge nozzle of the extrusion equipment with multiple-point screws. When replacing the die head, the replacement operation is cumbersome, time-consuming, and laborious. Moreover, the molten raw materials discharged into the die head in the extrusion equipment are easily affected by impurities, reducing the quality of the processed containers. High-temperature resistant plastics have higher requirements for impurities. If impurities are embedded inside, the material at the impurity part will be weak after the container is formed, thus reducing the high-temperature resistance performance, causing the container to be easily broken at high temperatures and affecting the product quality. If a filter screen is directly added for blocking, after the filter screen blocks impurities, the impurities blocked on the filter screen are likely to affect the discharge speed, resulting in low equipment efficiency, difficult control of the discharge volume, and also reducing the container processing quality. In view of the deficiencies of the existing technology, the present invention provides processing equipment for high-temperature resistant plastic containers to solve the above problems.

Among them, the design of the filter seat, extrusion die head, and loading unit enables the extrusion die head to be conveniently replaced according to the model of various target containers to be processed, thereby facilitating the subsequent blow molding system to produce high-temperature resistant plastic containers of various models. Through the design of the filter seat and the filtering mechanism, the raw materials discharged from the main body of the extruder into the extrusion die head are filtered, avoiding impurities from reducing the quality of the tube blank extruded by the extrusion die head. Coupled with the design of the cleaning component, the cleaning component facilitates maintaining the filtering mechanism unobstructed, smooth discharge at the position of the extrusion die head, and accurate discharge volume, thereby enabling good processing effects of high-temperature resistant plastic containers of various models and meeting the usage requirements.

[0013] Preferably, an embedding groove is formed on the first docking seat, and the first embedding seat is movably snap-connected in the embedding groove.

[0014] Preferably, a feed hopper is arranged on the main body of the extruder.

[0015] The present invention discloses processing equipment for high-temperature resistant plastic containers, and its beneficial effects are as follows: 1. The processing equipment for high-temperature resistant plastic containers improves the extrusion system. Among them, the design of the filter seat, extrusion die head, and loading unit enables the extrusion die head to be conveniently replaced according to the types of target containers to be processed, thus facilitating the subsequent blow molding system to produce various types of high-temperature resistant plastic containers. Through the design of the filter seat and the filtering mechanism, the raw materials discharged from the main body of the extruder into the extrusion die head are filtered, avoiding impurities from reducing the quality of the tube billets extruded by the extrusion die head. Coupled with the design of the cleaning component, the cleaning component facilitates keeping the filtering mechanism unobstructed, smooth discharging at the position of the extrusion die head, and accurate discharging volume. Furthermore, the processing effects of various types of high-temperature resistant plastic containers are good, meeting the usage requirements.

[0016] 2. The processing equipment for high-temperature resistant plastic containers, through the design of the pressing component, enables the first embedding seat and the second embedding seat to be installed inside the filter seat. When the filter seat is docked with the discharge nozzle, it can ensure that the second embedding seat receives the thrust of the ejector rod. Therefore, a positive pressure is always maintained between the first embedding seat and the second embedding seat, thereby driving the filter net and the scraper to fit tightly, improving the cleaning effect of the cleaning component on the filter net in the filtering mechanism.

Finally, the wedge-shaped clamping block is inserted into the locking groove. When the inclined surface of the wedge-shaped clamping block contacts and presses against the inner wall of the locking groove, the wedge-shaped clamping block exerts a lateral thrust on the inner wall of the locking groove, realizing the locking of the position of the insertion block while applying a thrust to the insertion block, so that the insertion block drives the second docking seat to move horizontally and squeeze the first docking seat, thereby ensuring a good locking effect between the first docking seat and the second docking seat.

Detailed implementation manners

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] By providing a processing device for high-temperature resistant plastic containers in the embodiments of the present application, the problems in the prior art during the use of processing devices are solved. In traditional extrusion devices, the die head is directly installed on the discharge nozzle of the extrusion device by multiple screws. When replacing the die head, the replacement operation is cumbersome, time-consuming and laborious. Moreover, the molten raw material discharged into the die head in the extrusion device is easily affected by impurities, reducing the quality of the processed containers. High-temperature resistant plastics have higher requirements for impurities. If impurities are embedded inside, the material at the impurity part will be weak after the container is formed, thus reducing the high-temperature resistance and causing the container to be easily broken at high temperatures, affecting the product quality. If a filter screen is directly added for blocking, after the filter screen blocks impurities, the impurities blocked on the filter screen are likely to affect the discharging speed, resulting in low equipment efficiency, difficult control of the discharging amount, and also reducing the container processing quality.

[0023] To better understand the above technical solution, the following will specifically describe the above technical solution in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0024] Embodiments of the present invention disclose a processing device for high-temperature resistant plastic containers. As shown in the attached Figures 1-12 figure, it includes an extrusion system and a blow molding system. The extrusion system includes an extrusion machine main body 1. A discharge nozzle 11 is provided on the extrusion machine main body 1. A filter seat 2 is installed on the discharge nozzle 11. An extrusion die head 3 is provided on the filter seat 2. The extrusion die head 3 is used to form the molten raw material discharged from the discharge nozzle 11 on the extrusion machine main body 1 into a tubular blank state, facilitating subsequent blow molding. The molten raw material is arranged between the extrusion die head 3 and the extrusion machine main body 1 and is used to filter the raw material; A loading unit 4 is provided between the discharge nozzle 11 and the filter seat 2. The loading unit 4 includes a first docking seat 41 provided on the discharge nozzle 11 and a second docking seat 42 provided on the filter seat 2. The second docking seat 42 and the first docking seat 41 are snap-connected, and the second docking seat 42 and the first docking seat 41 are easy to dock, making the disassembly and assembly between the discharge nozzle 11 and the filter seat 2 convenient. Therefore, the replacement operation of the extrusion die head 3 is ensured to be convenient; A filtering mechanism 5 is provided in the inner cavity of the filter seat 2. The filtering mechanism 5 includes a first embedding seat 51 and a second embedding seat 52 that are movably snap-connected inside the second docking seat 42. A filter screen 53 is provided inside the second embedding seat 52. A cleaning component 6 for preventing the filter screen 53 from being blocked is provided inside the first embedding seat 51; The cleaning component 6 includes a rotating shaft 63 provided inside the first embedding seat 51 and multiple groups of scraping plates 64 provided on the rotating shaft 63.

[0025] The high-temperature resistant plastic container processing equipment improves the extrusion system. Among them, the design of the filter seat 2, the extrusion die head 3 and the loading unit 4 enables the extrusion die head 3 to be conveniently replaced according to the types of target containers to be processed as required, so as to facilitate the subsequent blow molding system to manufacture high-temperature resistant plastic containers of various types. Through the design of the filter seat 2 and the filtering mechanism 5, the equipment filters the raw materials discharged from the main body 1 of the extruder into the extrusion die head 3, avoiding impurities from reducing the quality of the tube blank extruded by the extrusion die head 3. Coupled with the design of the cleaning component 6, the cleaning component 6 facilitates keeping the filtering mechanism 5 unobstructed, the discharge at the position of the extrusion die head 3 is smooth, and the discharge amount is accurate. Furthermore, the processing effect of high-temperature resistant plastic containers of various types is good, meeting the use requirements.

[0026] A socket 43 is fixedly connected to the first docking seat 41, a plug 44 is fixedly connected to the second docking seat 42, the plug 44 is movably inserted into the socket 43, and a locking mechanism 45 for limiting the plug 44 is provided on the first docking seat 41. When the device needs to dock the first docking seat 41 and the second docking seat 42, directly insert the plug 44 into the socket 43, and use the locking mechanism 45 to lock the position after insertion.

[0027] The locking mechanism 45 includes a support frame 451 fixedly connected to the first docking seat 41. An adjustment seat 452 is sleeved on the support frame 451. A carrier frame 453 is fixedly connected to the adjustment seat 452. A support plate 454 is provided on the carrier frame 453. A wedge-shaped clamping block 455 is provided on the support plate 454. A locking groove 441 is formed on the plug 44. The wedge-shaped clamping block 455 passes through the socket 43 and is movably clamped in the locking groove 441. The structure of the locking mechanism 45 is compact. The locking operation after the plug 44 and the socket 43 are clamped is simple, and the locking effect is good. After the plug 44 is inserted into the socket 43, adjust the position of the adjustment seat 452 on the support frame 451, so that the adjustment seat 452 drives the carrier frame 453 to move, the carrier frame 453 drives the support plate 454 to move, and the support plate 454 drives the wedge-shaped clamping block 455 to move. Finally, the wedge-shaped clamping block 455 is inserted into the inside of the locking groove 441. When the inclined surface of the wedge-shaped clamping block 455 contacts and presses against the inner wall of the locking groove 441, the wedge-shaped clamping block 455 exerts a lateral thrust on the inner wall of the locking groove 441, realizing the locking of the position of the plug 44 and applying a thrust to the plug 44, so that the plug 44 drives the second docking seat 42 to laterally move and press against the first docking seat 41, thereby ensuring a good position locking effect between the first docking seat 41 and the second docking seat 42.

[0028] A lead screw 456 is rotatably connected to the support frame 451. The lead screw 456 is threadedly connected to the adjustment seat 452. Through the design of the lead screw 456, the position adjustment of the adjustment seat 452 is made convenient. When adjusting the position of the adjustment seat 452, simply rotate the lead screw 456 directly. The lead screw 456 drives the adjustment seat 452 to move along the support frame 451 and adjust the position. When the rotation of the lead screw 456 stops, the adjustment seat 452 is self-locked.

[0029] When it is necessary to use the locking mechanism 45 to release the position locking of the insertion block 44 and the socket 43, simply rotate the lead screw 456 in the reverse direction directly. When the lead screw 456 rotates, it drives the adjustment seat 452 to move. The adjustment seat 452 moves along the support frame 451 and drives the carrier frame 453 to move. The carrier frame 453 drives multiple groups of support plates 454 provided thereon. The support plates 454 drive multiple groups of wedge-shaped locking blocks 455 provided thereon to move. Therefore, multiple groups of wedge-shaped locking blocks 455 move synchronously to unlock the multiple groups of insertion blocks 44 and sockets 43 that are clamped and limited synchronously. After the locking state is released, pull the filter seat 2 horizontally, and the filter seat 2 can drive the second docking seat 42 to move. The second docking seat 42 drives the insertion block 44 to move and disengage from the socket 43, so that the first docking seat 41 and the second docking seat 42 are disengaged, realizing the disassembly of the extrusion die head 3 and the filter seat 2.

[0030] After the extrusion die head 3 and the filter seat 2 are disassembled, the filter mechanism 5 and the cleaning component 6 provided inside can be directly taken out, that is, the first embedding seat 51 and the second embedding seat 52 are pulled out, so as to ensure that the internal filter screen 53, the scraping plate 64, the rotating shaft 63 and other components are convenient for regular inspection and maintenance, and also make the whole device convenient for quickly replacing the model of the extrusion die head 3.

[0031] The cleaning component 6 further includes an arc-shaped limiting plate 61 fixedly connected inside the first embedding seat 51. A material passing opening 62 is formed on the arc-shaped limiting plate 61. Through the design of the cleaning component 6, the filter screen 53 in the filter mechanism 5 is convenient to clean. The principle is that when the molten raw material passes through the inside of the filter seat 2, it directly passes through the first embedding seat 51 and the second embedding seat 52, and finally passes through the filtration of the filter screen 53. The molten raw material enters the extrusion die head 3 from the inside of the filter seat 2. The cleaning component 6 includes a rotating shaft 63 and a scraping plate 64. The scraping plate 64 is attached to the filter screen 53. When the molten raw material enters the inside of the first embedding seat 51, it will push the scraping plate 64 to rotate along the rotating shaft 63. Therefore, the scraping plate 64 is used to clean the surface of the filter screen 53. Among them, the arc-shaped limiting plate 61 forms a limit on the scraping plate 64, and the material passing opening 62 guides the molten raw material, so that the raw material flows and pushes the scraping plate 64. Finally, the impurities rotate continuously in the space formed by the scraping plate 64, the first embedding seat 51 and the second embedding seat 52, and will not block the mesh holes of the filter screen 53.

[0032] The filter base 2 is provided with a pressing component 7. The pressing component 7 includes a sleeve 71 fixedly connected to the filter base 2. A spring 72 is fixedly connected inside the sleeve 71. A slider 73 is fixedly connected to the spring 72. The slider 73 is slidably connected inside the sleeve 71. A ejector rod 74 is provided on the slider 73. The ejector rod 74 passes through the filter base 2 and fits with the second embedded seat 52. Through the design of the pressing component 7, when the first embedded seat 51 and the second embedded seat 52 are installed inside the filter base 2 and the filter base 2 is docked with the discharge nozzle 11, it can ensure that the second embedded seat 52 is subjected to the thrust of the ejector rod 74. Therefore, a positive pressure is always maintained between the first embedded seat 51 and the second embedded seat 52, thereby driving the filter screen 53 and the scraper 64 to fit tightly, improving the cleaning effect of the cleaning component 6 on the filter screen 53 in the filtering mechanism 5.

[0033] A limiting hole 521 corresponding to the position of the ejector rod 74 is formed on the second embedded seat 52. The thrust of the ejector rod 74 is provided by the spring 72. The elastic force of the spring 72 is applied to the slider 73, and then applied to the ejector rod 74 through the slider 73. Through the design of the limiting hole 521, the ejector rod 74 is easily clamped inside the limiting hole 521, thereby realizing axial limitation and ensuring stable force at the contact position between the second embedded seat 52 and the ejector rod 74.

[0034] When the first embedded seat 51 and the second embedded seat 52 are installed inside the filter base 2 and the first docking seat 41 and the second docking seat 42 are docked, after the first embedded seat 51 and the second embedded seat 52 are installed, they will synchronously squeeze the ejector rod 74, causing the ejector rod 74 to drive the slider 73 to move and squeeze the spring 72, thereby increasing the elastic potential energy of the spring 72. The elasticity of the spring 72 is finally applied to the slider 73, the ejector rod 74 and the second embedded seat 52, thereby improving the fitting between the first embedded seat 51 and the second embedded seat 52, that is, ensuring the tight fitting state of the filter screen 53 and the scraper 64, and improving the cleaning effect of the cleaning component 6 on the filter screen 53.

[0035] A filter screen support 531 is provided on the outer side of the filter screen 53. The filter screen support 531 is movably clamped inside the second embedded seat 52. A round hole is provided on the filter screen support 531. A threaded hole is provided inside the second embedded seat 52. Therefore, it is convenient to fix the filter screen support 531 with bolts, making the disassembly and assembly of the filter screen 53 convenient. Therefore, it is ensured that the filter screen 53 is easy to maintain. When the filter screen 53 is damaged subsequently, it is convenient to quickly remove the first embedded seat 51 and the second embedded seat 52 and replace the filter screen 53, making the overall maintenance of the device convenient.

[0036] An embedding groove 411 is formed in the first docking seat 41, and the first embedding seat 51 is movably clamped in the embedding groove 411. Through the design of the embedding groove 411, the device provides a limit for the first embedding seat 51 to ensure the stable installation force of the first embedding seat 51. A feed hopper 12 is provided on the main body 1 of the extruder, and the feed hopper 12 facilitates the addition of plastic pellet raw materials into the main body 1 of the extruder.
