Description

Technical Field

[0001] This utility model relates to the field of injection molding auxiliary equipment, and in particular to a material tube cleaning device. Background Technology

[0002] In injection molding production lines, the feeder connects to the hopper on the injection molding machine via a conveying pipe, continuously supplying plastic granules. However, when production plans change and a different type of plastic needs to be used, cleaning the residual plastic in the conveying pipe becomes an indispensable process. Currently, this cleaning mainly relies on manual operation, requiring workers to use specific tools to scrape and clean deep inside the pipe. However, this traditional manual cleaning method has significant drawbacks: low cleaning efficiency, making it difficult to meet the needs of rapid production changes. More problematic is that as the length of the conveying pipe increases, cleaning efficiency declines significantly, and the cleaning difficulty increases exponentially. This not only consumes substantial manpower and time costs but may also affect the quality of subsequent products due to incomplete cleaning. Therefore, it is necessary to develop a pipe cleaning device to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a material pipe cleaning device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A material pipe cleaning device includes a pipe connecting block, a conveying pipe, a feeding pipe, a mounting base, a filter, and a switching assembly. The pipe connecting block has a first cavity. The conveying pipe is fixed to the pipe connecting block and communicates with the first cavity. The feeding pipe is fixed to the pipe connecting block and communicates with the first cavity. The mounting base has a second cavity and is fixed to the pipe connecting block. The first cavity and the second cavity communicate with each other. The filter is fixed to the mounting base and communicates with the second cavity. The switching assembly includes a telescopic cylinder, a control valve, a drive rod, and an elastic plug. The telescopic cylinder is fixed to the mounting base. The control valve is fixed to the mounting base and communicates with the telescopic cylinder via a hose. The left end of the drive rod corresponds to the second cavity and is connected to the power output end of the telescopic cylinder. The right end of the drive rod corresponds to the first cavity. The elastic plug is fixed to the right end of the drive rod and corresponds to the feeding pipe. The elastic plug is cylindrical and its diameter is larger than the diameter of the feeding pipe.

[0006] Further description of the present invention: The right end of the conveying pipe is connected to the left side of the first cavity, the feeding pipe is connected to the right side of the first cavity, and the lower end of the pipe connecting block is provided with a guiding slope, which corresponds to the right side of the conveying pipe and the lower part of the feeding pipe.

[0007] Further description of the present invention: It also includes a viewing window, which is fixed on the pipe connection block and corresponds to the feed pipe and the elastic rubber plug. The viewing window is made of transparent material.

[0008] Further description of this utility model: Two sets of viewing windows are provided and fixed on the front and rear sides of the pipe connection block respectively.

[0009] Further description of this utility model: The elastic rubber stopper is made of natural rubber or nitrile rubber.

[0010] Further description of the present invention: The switching assembly also includes a first nut and a second nut, the right end of the drive rod is threaded, the first nut and the second nut are both threadedly connected to the right end of the drive rod, and the elastic rubber plug is sleeved on the drive rod and corresponds between the first nut and the second nut.

[0011] The beneficial effects of this utility model are as follows: When the injection molding machine is running normally, the drive rod is in the retracted state, and the elastic plug seals the connection between the first cavity and the second cavity. Under the action of the airflow from the feeder, the plastic particles pass through the conveying pipe, the first cavity, and the feeding pipe in sequence, and then enter the hopper of the injection molding machine, thus completing the conveying of plastic. At the same time, a suction machine is configured and connected to the conveying pipe through a pipe. At this time, the suction machine is not working. When it is necessary to change the plastic type, the injection molding machine and the feeder stop working, and the control valve controls the telescopic cylinder to extend the drive rod. The elastic plug seals the opening of the feeding pipe, and the first cavity and the second cavity are connected. The suction machine is started. Under the action of the airflow from the suction machine, the external gas enters the second cavity after being filtered to remove external dust. Then, it passes through the first cavity and the conveying pipe in sequence and flows to the suction machine, thereby driving the residual plastic particles in the conveying pipe to be conveyed and collected towards the suction machine, quickly completing the cleaning work of the conveying pipe. The advantage of this design is that it can quickly and thoroughly clean residual plastic in the conveying pipe, and it can adapt to the cleaning of conveying pipes of various lengths, saving time and effort.

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figures 1 to 2 As shown, a material pipe cleaning device includes a pipe connecting block 1, a conveying pipe 2, a feeding pipe 3, a mounting base 4, a filter 5, and a switching assembly 6. The pipe connecting block 1 has a first cavity 11. The conveying pipe 2 is fixed to the pipe connecting block 1 and communicates with the first cavity 11. The feeding pipe 3 is fixed to the pipe connecting block 1 and communicates with the first cavity 11. The mounting base 4 has a second cavity 41 and is fixed to the pipe connecting block 1. The first cavity 11 communicates with the second cavity 41. The filter 5 is fixed to the mounting base 4 and communicates with the second cavity 41. The switching assembly 6... Component 6 includes a telescopic cylinder 61, a control valve 62, a drive rod 63, and an elastic plug 64. The telescopic cylinder 61 is fixed on the mounting base 4. The control valve 62 is fixed on the mounting base 4 and is connected to the telescopic cylinder 61 through a hose. The left end of the drive rod 63 corresponds to the second cavity 41 and is connected to the power output end of the telescopic cylinder 61. The right end of the drive rod 63 corresponds to the first cavity 11. The elastic plug 64 is fixed to the right end of the drive rod 63 and corresponds to the feed pipe 3. The elastic plug 64 is cylindrical and its diameter is larger than the diameter of the feed pipe 3.

[0018] When the injection molding machine is operating normally, the drive rod 63 is in the retracted state, and the elastic plug 64 seals the connection between the first cavity 11 and the second cavity 41. Under the airflow of the feeder, the plastic granules pass sequentially through the conveying pipe 2, the first cavity 11, and the feeding pipe 3 before entering the hopper of the injection molding machine, thus completing the plastic conveying process. A suction machine is also configured, connected to the conveying pipe 2 via a pipe. At this time, the suction machine is not in operation. When it is necessary to change the plastic type, the injection molding machine and the feeder stop working, and the control valve... The telescopic cylinder 61 extends the drive rod 63, and the elastic plug 64 seals the opening of the feed pipe 3. Simultaneously, the first chamber 11 and the second chamber 41 are connected. The suction machine is activated, and under the airflow of the suction machine, external gas passes through the filter 5 to remove dust before entering the second chamber 41. It then passes through the first chamber 11 and the conveying pipe 2 before flowing towards the suction machine, thereby conveying and collecting the residual plastic particles in the conveying pipe 2, quickly completing the cleaning of the conveying pipe 2. The advantage of this design is that it can quickly and thoroughly clean the residual plastic in the conveying pipe 2, and it can adapt to cleaning conveying pipes of various lengths, saving time and labor.

[0019] The right end of the conveying pipe 2 is connected to the left side of the first cavity 11, and the feeding pipe 3 is connected to the right side of the first cavity 11. The lower end of the pipe connecting block 1 is provided with a guiding slope 12, which corresponds to the right side of the conveying pipe 2 and the lower part of the feeding pipe 3.

[0020] In the plastic conveying state, plastic granules are sent out from the right end of the conveying pipe 2 and flow into the feed pipe 3 quickly through the guiding effect of the guide slope 12, so that the plastic will not accumulate in the first cavity 11.

[0021] This design also includes a viewing window 7, which is fixed to the pipe connection block 1 and corresponds to the area between the feed pipe 3 and the elastic rubber stopper 64. The viewing window 7 is made of transparent material. Through the viewing window 7, the material conveying status inside the first cavity 11 and the operating status of the elastic rubber stopper 64 can be observed at any time.

[0022] Two sets of viewing windows 7 are provided and fixed on the front and rear sides of the pipe connection block 1, respectively. This allows operators to observe the situation inside the first cavity 11 from both the front and rear sides.

[0023] The elastic rubber stopper 64 is made of natural rubber or nitrile rubber. Natural rubber has excellent elasticity and softness; it is resistant to low temperatures (-50℃~60℃); and it is resistant to water, weak acids and weak alkalis. Nitrile rubber, on the other hand, has excellent oil resistance (mineral oil, lubricating oil); it has good wear resistance and better heat resistance than natural rubber (-40℃~100℃).

[0024] The switching assembly 6 also includes a first nut 65 and a second nut 66. The right end of the drive rod 63 is threaded, and the first nut 65 and the second nut 66 are both threadedly connected to the right end of the drive rod 63. An elastic rubber plug 64 is sleeved on the drive rod 63 and corresponds between the first nut 65 and the second nut 66.

[0025] The elastic rubber plug 64 is clamped and fixed by the first nut 65 and the second nut 66, which facilitates the installation and removal of the elastic rubber plug 64 and also makes it easy to fine-tune the position of the elastic rubber plug 64.

[0026] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
