[0031] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] like Figure 1-2 The present embodiment provides a cleaning device for laboratory extruder parts, comprising: a mounting frame 1; a cleaning assembly 2, the cleaning assembly 2 comprising a fixed rod 21 and a vibrating and rotating cleaning unit 22, one end of the fixed rod 21 being movably and lockedly connected to the mounting frame 1, and the other end of the fixed rod 21 being connected to the vibrating and rotating cleaning unit 22; a plurality of cooling assemblies 3, the cooling assemblies 3 comprising a cooling plate 31 movably and lockedly connected to the mounting frame 1, and a circulation pipe 32 connected to the cooling plate 31, with a water inlet 321 and a water outlet 322 respectively provided at both ends of the circulation pipe 32; a heating assembly 4 and a storage net 5, both of which are connected to the mounting frame 1.

[0034] Specifically, the mounting frame 1 is used to carry the cleaning component 2, several cooling components 3, the heating component 4 and the storage net 5; the fixing rod 21 is used to fix the vibration and rotation cleaning unit 22 on the mounting frame 1, and one end of the fixing rod 21 and the mounting frame 1 can be manually rotated and raised and lowered, and locked by fasteners, or can be rotated by a motor and raised and lowered by a telescopic cylinder; the vibration and rotation cleaning unit 22 is used to vibrate and rotate and clean the die head, the feed hopper and the extruder head and other parts, and the double cleaning is convenient for making the cleaning thorough; the heating component 4 is used to heat the parts, and the heating component 4 can be heated by resistance heating, infrared heating and the like; the cooling The cooling plate 31 is used to contact the parts, and the circulation pipe 32 circulates the coolant through the water inlet 321 and the water outlet 322, so as to take away the heat of the cooling plate 31 in time, so that the cooling plate 31 always has good cooling performance, avoids using water to directly rinse the parts during cooling, and then wipes the water on the parts, so that the cooling step is simple, thereby making the cleaning step simple, and thus facilitating shortening the cleaning time. Among them, the cooling plate 31 and the mounting frame 1 can be manually rotated and raised and lowered, and locked by fasteners, or can be rotated by a motor and raised and lowered by a telescopic cylinder; the storage net 5 is used to place parts and facilitate the cleaned impurities to pass through the storage net 5.

[0035] Further, such as Figure 2 The vibration and rotation cleaning unit 22 includes a vibration motor 221 and a plurality of rotation motors 222, both of which are connected to the other end of the fixed rod 21. The output shafts of the plurality of rotation motors 222 are each connected to a cleaning brush 223. Specifically, the vibration motor 221 drives the fixed rod 21, the plurality of rotation motors 222, and the plurality of cleaning brushes 223 to vibrate in sequence through its own vibration, so that the plurality of cleaning brushes 223 can achieve vibration cleaning. The plurality of rotation motors 222 are used to drive the plurality of cleaning brushes 223 to achieve rotation cleaning. This double cleaning method ensures thorough cleaning.

[0036] Further, such as Figure 2 The vibration and rotation cleaning unit 22 further includes a fixed plate 224 connected to the other end of the fixed rod 21. The vibration motor 221 and the plurality of rotating motors 222 are all connected to the fixed plate 224. Specifically, the fixed plate 224 is used to fix the vibration motor 221 and the plurality of rotating motors 222 on the fixed rod 21, so that the vibration motor 221 can vibrate by itself, thereby driving the fixed plate 224, the plurality of rotating motors 222 and the plurality of cleaning brushes 223 to vibrate in turn.

[0037] Further, such as Figure 1The heating assembly 4 includes: a heater 41; two flexible heat-conducting wires 42, one end of each of the two flexible heat-conducting wires 42 being connected to the heater 41; and two first clamps 43 correspondingly connected to the other ends of the two flexible heat-conducting wires 42. Specifically, the heater 41 is used for heating and transmits heat to the two first clamps 43 via the two flexible heat-conducting wires 42. The two first clamps 43 clamp the component to facilitate heating. The heater 41 preferably uses a resistive heating method, and the flexible heat-conducting wires 42 are themselves flexible, thereby facilitating adjustment of the position of the first clamps 43. The first clamps 43 can be clamped with bolts or springs. The number of flexible heat-conducting wires 42 and the number of first clamps 43 are both two, which facilitates comprehensive heating of the component.

[0038] Further, such as Figure 1 , further comprising: two screws 61 connected to the two ends of the mounting frame 1; two second clamps 62 threadedly connected to the two screws 61; and a clamping space 63 formed between the two second clamps 62. Specifically, the size of the clamping space 63 can be adjusted by rotating the two second clamps 62 along the two screws 61 to facilitate clamping parts of different sizes.

[0039] Further, such as Figure 1 , further comprising a collecting hopper 7 detachably connected to the mounting frame 1. The storage net 5 and the collecting hopper 7 are sequentially arranged along the direction of gravity. Specifically, the collecting hopper 7 is used to collect impurities that fall from the storage net 5. Since the collecting hopper 7 is detachably connected to the mounting frame 1, the impurities in the collecting hopper 7 can be easily dumped in a timely manner.

[0040] Further, such as Figure 1 , also includes a retractable lighting assembly 8 connected to the mounting frame 1. Specifically, the retractable lighting assembly 8 is used for lighting, which is convenient for real-time observation of the cleaning status of parts. The retractable lighting assembly 8 can be specifically retracted and adjusted through a metal shaped hose.

[0041] Further, such as Figure 1 , further comprising: a plurality of universal wheels 91 connected to the mounting frame 1; and a retractable handle 92 connected to the mounting frame 1. Specifically, the plurality of universal wheels 91 facilitates the movement of the cleaning device of the present application; and the retractable handle 92 facilitates the staff to hold and thus facilitate the staff to move the cleaning device of the present application.

[0042] During cleaning, according to different operation requirements, it is divided into three types, as follows:

[0043] Type 1: The simplest cleaning method without any additional requirements: place the parts such as the feed hopper on the storage net 5, fix them with two second clamps 62, rotate and lift the fixing rod 21 and the vibration and rotation cleaning unit 22 to the appropriate position, start the vibration and rotation cleaning unit 22 to perform dual cleaning of the parts by vibration and rotation. The impurities generated during the cleaning process enter the collection bucket 7 from the storage net 5. After the experiment, the impurities can be poured out through the collection bucket 7. During the operation, the retractable lighting component 8 can be used to pay attention to the cleaning process and the post-cleaning inspection and confirmation, so as to achieve the purpose of fast, clean and no damage to the extruder, and avoid the appearance of old rubber due to multiple cleaning failures, which makes a part of the extruder unable to meet the experimental requirements and scrapped;

[0044] Type 2: Components need to be kept at a certain temperature for the next test. Under high temperature conditions, cleaning is easier or the time required to clean the equipment is shorter. When the temperature drops and repeated heating is required, the heater 41 heats the components to the required temperature and then uses the cleaning method of type 1 to clean them. This allows the components to always maintain the experimental temperature, reduces the difficulty of cleaning, greatly shortens the reheating time after assembly, and avoids the repeated heating and cleaning caused by slow manual cleaning speed.

[0045] Type three, when parts such as feed hoppers need to be kept at room temperature in the next experiment after high-temperature experiments, they should first be cleaned using the cleaning method in type two, and then the cooling plate 31 and the circulation pipe 32 should be moved to a suitable position so that the cooling plate 31 and the parts are in conflict with each other, avoiding the use of water to directly rinse the parts during cooling, and then the water on the parts should be wiped off, so that the cooling step is simple, thereby making the cleaning step simple, and thus shortening the cleaning time, eliminating the adverse effects of residual water vapor on the experimental results. The cleaning device of the present application also has a retractable handle 92 and several universal wheels 91 so that it will not be limited to a certain position and has a wider application space.

[0046] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
