Description

Technical Field

[0001] The utility model belongs to the field of PBT engineering plastic processing, and particularly relates to a mixing device for PBT engineering plastic processing with a cleaning structure. Background Technique

[0002] PBT (polybutylene terephthalate) is a commonly used engineering plastic with excellent mechanical properties, heat resistance and chemical resistance, and is widely used in industries such as electronics, electrical and automotive. In the processing of PBT, the mixing device plays a crucial role, mainly used to uniformly mix PBT resin with other additives (such as fillers, toughening agents, masterbatches, etc.) to achieve the required performance and characteristics.

[0003] For example, a Chinese published patent with the patent number CN218139147U points out a mixing device for PBT engineering plastic processing with a self-scraping and cleaning structure; in this cited document, the raw materials on the inner wall of the outer shell are scraped off by a scraper, and then the outer wall of the outer shell is knocked by a movable rod, which can cooperate with the scraper to better clean the inner wall of the outer shell.

[0004] In the actual use of the above-cited patent, although the inner wall of the mixing device is cleaned, it still has certain limitations in use; that is, the cleaning structure in this document can only clean the inside of the device and cannot clean the feeding pipe of the device; due to the slender and different lengths of the feeding pipes of the PBT engineering plastic mixing device, the cleaning is more cumbersome, and the traditional cleaning method mostly uses manual cleaning. It is difficult for manual cleaning to clean according to the depth of different feeding pipes, so that every corner of the pipeline cannot be reached, resulting in residues at the feeding pipe orifice that cannot be completely removed. If the cleaning is not thorough, the residual materials may cross-contaminate the materials processed subsequently, thus affecting the quality of the products produced subsequently. Therefore, a mixing device for PBT engineering plastic processing with a cleaning structure is proposed to solve the cleaning method in the cited document. Summary of the Utility Model

[0005] In view of one or more of the above defects or improvement requirements in the prior art, the utility model provides a mixing device for PBT engineering plastic processing with a cleaning structure, which has the advantages of supplementing the cleaning of the mixing device for PBT engineering plastic processing, being able to clean the feeding pipe of the device, having thorough cleaning, and being adaptable to feeding pipes of different sizes.

[0006] To achieve the above object, the utility model provides a mixing device for PBT engineering plastic processing with a cleaning structure, including a PBT engineering plastic mixing device body, and two feeding pipes are assembled on the PBT engineering plastic mixing device body;

[0007] An installation bracket is installed on the main body of the PBT engineering plastic mixing device; two sets of lifting and adjusting components are installed on the installation bracket, and a set of cleaning structures are assembled on each of the two sets of lifting and adjusting components;

[0008] The two sets of cleaning structures move vertically and are arranged directly above one of the feed pipes;

[0009] Among them, each of the two sets of lifting and adjusting components includes an installation base arranged on the installation bracket, an adjusting seat is installed on the installation base, a threaded lead screw is rotatably arranged in the adjusting seat, a lead screw nut is externally engaged with the threaded lead screw, and a slider seat is sleeved outside the lead screw nut;

[0010] The cleaning structure includes a bearing seat arranged on the side of the slider seat, a threaded bushing is installed at the bottom of the bearing seat, a cleaning brush rod is in threaded connection with the threaded bushing, and a number of soft brush hairs are wound around the outside of the cleaning brush rod.

[0011] As a further improvement of the present utility model, the lifting and adjusting component further includes a bearing seat arranged in the adjusting seat, a deep groove ball bearing member is arranged in the bearing seat, and the bottom of the threaded lead screw is in rotational cooperation with the deep groove ball bearing member.

[0012] As a further improvement of the present utility model, a reciprocating motor is assembled at the top end of the adjusting seat, and the output end of the reciprocating motor penetrates through the adjusting seat and is connected to the top end of the threaded lead screw.

[0013] As a further improvement of the present utility model, the bearing seat is hollow, and a cleaning water tank is installed above it. A communicating water pipe is connected to the bottom of the cleaning water tank and extends into the bearing seat.

[0014] As a further improvement of the present utility model, a solenoid valve is installed on the communicating water pipe, and the solenoid valve is used to control the conduction of the communicating water pipe.

[0015] As a further improvement of the present utility model, the cleaning brush rod is of a hollow tube structure, and its upper part passes through the threaded bushing and is communicated with the bearing seat; a number of holes are opened through the outside of the cleaning brush rod.

[0016] Generally speaking, compared with the prior art, the beneficial effects of the above technical solutions conceived by the present utility model include:

Thus, through cooperation with the water flow conduction in the bearing seat, the cleaning brush rod and the soft brush in the cleaning structure can reciprocally brush the inner wall of the feed pipe. Compared with the cleaning method in the cited document, the processing and mixing equipment of the present application, by adding a lifting adjustment component at the feed pipe and performing reciprocating lifting cleaning on it with the cleaning structure, enables the feed pipe in the PBT engineering plastics mixing equipment body to be thoroughly cleaned by the cleaning structure. At the same time, the flushing effect of the water flow can quickly carry away the residues cleaned by the soft brush, avoiding the need for repeated cleaning and improving the cleaning efficiency of the feed pipe.

[0018] The mixing equipment for PBT engineering plastics processing with a cleaning structure according to the present utility model, in actual use, replaces the traditional manual cleaning with the automatic cleaning of the lifting adjustment component and the cleaning structure, greatly reducing the participation degree of workers, and thus significantly reducing the labor intensity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment

[0026] As Figures 1-4 shown, a mixing device for processing PBT engineering plastics with a cleaning structure includes a PBT engineering plastic mixing device body 1, and two feed pipes 11 are assembled on the PBT engineering plastic mixing device body 1;

[0027] An installation bracket 2 is installed on the PBT engineering plastic mixing device body 1; two sets of lifting and adjusting components 3 are installed on the installation bracket 2, and a set of cleaning structures 4 are assembled on each of the two sets of lifting and adjusting components 3;

[0028] The two sets of cleaning structures 4 move vertically and are arranged directly above one of the feed pipes 11;

[0029] Among them, each of the two sets of lifting and adjusting components 3 includes an installation base 31 arranged on the installation bracket 2, an adjusting seat 32 is installed on the installation base 31, a threaded lead screw 34 is rotatably arranged in the adjusting seat 32, a lead screw nut 35 is externally engaged with the threaded lead screw 34, and a slider seat 36 is sleeved outside the lead screw nut 35;

[0030] The cleaning structure 4 includes a bearing seat 41 arranged on the side of the slider seat 36, a threaded shaft sleeve 45 is installed at the bottom of the bearing seat 41, a cleaning brush rod 46 is threadedly connected inside the threaded shaft sleeve 45, and a plurality of soft brush hairs 47 are arranged around the cleaning brush rod 46.

[0031] In this embodiment, in actual use, through the mutual movement and cooperation of multiple structures in the lifting and adjusting component 3 and the cleaning structure 4, the provided lifting and adjusting component 3 can drive the cleaning structure 4 to perform reciprocating lifting motion in the vertical direction. Thus, by cooperating with the water flow conduction in the bearing seat 41, the cleaning brush rod 46 and the soft brush hairs 47 in the cleaning structure 4 can reciprocally brush the inner wall of the feed pipe 11; compared with the cleaning method in the cited document, the processing and mixing device of the present application performs reciprocating lifting cleaning on the feed pipe 11 by adding a lifting and adjusting component 3 and a cleaning structure 4 at the feed pipe 11, so that the feed pipe 11 in the PBT engineering plastic mixing device body 1 can be thoroughly cleaned by the cleaning structure 4. At the same time, the scouring effect of the water flow can quickly carry away the residues cleaned by the soft brush hairs 47, avoiding the need for repeated cleaning and improving the cleaning efficiency of the feed pipe 11.

[0032] Furthermore, in actual use, the automated cleaning by the lifting and adjusting component 3 and the cleaning structure 4 replaces the traditional manual cleaning, greatly reducing the degree of worker participation and significantly reducing the labor intensity. Especially when cleaning high-temperature, high-pressure, hazardous chemicals or relatively narrow feed pipes 11, mechanized cleaning not only reduces the manpower burden but also improves the efficiency of the cleaning work.

[0033] Specifically, referring to Figures 1-3 , the lifting and adjusting component 3 further includes a bearing seat 33 disposed within the adjusting seat 32. A deep groove ball bearing is disposed within the bearing seat 33, and the bottom of the threaded lead screw 34 is rotationally engaged with the deep groove ball bearing.

[0034] In this embodiment, in actual use, the deep groove ball bearing disposed within the bearing seat 33 can provide smoother rotational control for the threaded lead screw 34. Thus, when the cleaning structure 4 is assembled on the side of the slider seat 36, it can provide higher load capacity for the slider seat 36 and ensure the stable rotation of the threaded lead screw 34.

[0035] Specifically, referring to Figures 1-3 , a reciprocating motor 37 is assembled at the top of the adjusting seat 32. The output end of the reciprocating motor 37 penetrates through the adjusting seat 32 and is connected to the top end of the threaded lead screw 34.

[0036] In this embodiment, the reciprocating motor 37 provided can be used to control the rotation of the threaded lead screw 34. In use, the user connects a power supply to the reciprocating motor 37, enabling the output end of the reciprocating motor 37 to drive the threaded lead screw 34 to rotate.

[0037] Furthermore, the reciprocating motor 37 provided is an existing mature structural component, and its power connection method is prior art. Also, the reciprocating control circuit can be achieved through simple programming by those skilled in the art, which belongs to the common knowledge in the field. Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0038] Specifically, referring to Figure 2 and Figure 4 , the carrier seat 41 is hollow and a cleaning water tank 42 is installed above it. A connecting water pipe 43 is connected to the bottom of the cleaning water tank 42 and extends into the carrier seat 41.

[0039] In this embodiment, through the connection between the carrier seat 41 and the cleaning water tank 42, when the user injects water source and cleaning liquid into the carrier seat 41, the water source and cleaning liquid can enter the cleaning water tank 42 from the carrier seat 41 through the connecting water pipe 43 provided.

[0040] Specifically, referring to Figure 4, a solenoid valve 44 is installed on the connecting water pipe 43, and the solenoid valve 44 is used to control the conduction of the connecting water pipe 43.

[0041] In this embodiment, during use, when the cleaning structure 4 is moving vertically up and down, the user can inject water source and cleaning liquid into the cleaning water tank 42, and at the same time open the solenoid valve 44. At this time, through the conduction control of the solenoid valve 44, the water source and cleaning liquid in the cleaning water tank 42 can enter the bearing seat 41 through the connecting water pipe 43.

[0042] Furthermore, the set solenoid valve 44 is an existing mature structural part, its power connection method is prior art, and the reciprocating control circuit can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the field. Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0043] Specifically, referring to Figure 4 , the cleaning brush rod 46 is of a hollow tube structure and its upper part passes through the threaded bushing 45 and is connected to the bearing seat 41; a number of holes are formed through the outside of the cleaning brush rod 46.

[0044] In this embodiment, through the number of holes on the set cleaning brush rod 46, when the water source and cleaning liquid in the bearing seat 41 enter the bearing seat 41, they can flow gradually downward from the top of the cleaning brush rod 46 and at the same time seep out from the holes outside the cleaning brush rod 46. At this time, when the soft brush 47 enters the feed pipe 11 for reciprocating brushing, the water source and cleaning liquid can be directly brought into the feed pipe 11, thereby cleaning the feed pipe 11.

[0045] Furthermore, it should be noted that during use, the soft brush 47 is driven by the lifting and adjusting assembly 3 to move reciprocally, which can cover every corner of the feed pipe 11 with different depths on the PBT engineering plastic mixing equipment body 1. Especially in the longer feed pipe 11, the physical contact of the soft brush 47 can directly remove the stubborn dirt, sediment and PRT engineering plastic impurities that may adhere to the inner wall of the feed pipe 11. Compared with simple water flow flushing and manual cleaning, the friction generated by the reciprocating contact of the soft brush 47 in this application enhances the cleaning effect, so that even in difficult-to-reach areas, the cleaning can be done without dead corners;

[0046] Furthermore, the user can disassemble and replace the cleaning brush rod 46 and the soft brush 47 with different diameters, so that the set cleaning structure 4 can also adapt to feed pipes 11 with different diameters, thereby realizing the thorough cleaning of the PBT engineering plastic mixing equipment body 1 and improving the cleaning adaptation range for PBT engineering plastic mixing equipment bodies 1 of different models.

[0047] PBT engineering plastic processing mixing equipment with a cleaning structure of the present utility model:

[0048] First step: When the user needs to clean the feed pipe 11, by driving the lifting and adjusting assembly 3, the cleaning structure 4 installed on the lifting and adjusting assembly 3 can perform vertical lifting movement, so that the reciprocating cleaning of the feed pipe 11 can be realized through the cleaning structure 4;

[0049] Second step: When the user drives and adjusts the lifting and adjusting assembly 3, the user connects the power supply to the reciprocating motor 37, so that the output end of the reciprocating motor 37 can drive the threaded lead screw 34 to rotate. Limited by the adjusting seat 32 to the threaded lead screw 34, the lead screw nut 35 engaged outside the threaded lead screw 34 can drive the slider seat 36 to reciprocate up and down along the stroke range of the threaded lead screw 34. At this time, 4 installed on the side of the slider seat 36 can follow the slider seat 36 to perform synchronous lifting movement;

[0050] Third step: When the cleaning structure 4 performs vertical lifting movement, the user can inject water source and cleaning liquid into the cleaning water tank 42, and at the same time open the solenoid valve 44, so that the water source and cleaning liquid in the cleaning water tank 42 can enter the bearing seat 41 through the connecting water pipe 43. Thus, through the conduction between the bearing seat 41 and the cleaning brush rod 46, the water source and cleaning liquid can seep out from the holes outside the cleaning brush rod 46, so that the soft brush 47 can adsorb them. At this time, through the reciprocating lifting movement of the cleaning structure 4 by the lifting and adjusting assembly 3, the soft brush 47 can enter the feed pipe 11, so as to realize the reciprocating brushing of the feed pipe 11.

[0051] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
