Description

Technical Field

[0001] The utility model relates to the technical field of microbiology detection, in particular to a slapping device. Background Art

[0002] There are many national standard methods for food microbiology testing, and most testing items usually use the coating method and pouring method. The main steps of the pouring method and coating method for food microbiology testing are as follows: ① Pouring method: adding liquid to the sample, tapping to homogenize, taking liquid, gradient dilution, adding samples to the culture dish, pouring and shaking the culture medium, covering the top culture medium, culturing, and counting colonies; ② Coating method: adding liquid to the sample, tapping to homogenize, taking liquid, gradient dilution, adding samples to the culture dish, coating with a coating rod, culturing, and counting colonies.

[0003] It can be seen that both methods include the step of tapping homogenization. However, the traditional inspection method usually requires manual tapping homogenization, which is inefficient and not very accurate, and cannot meet the needs of the modern food industry for food safety testing. Secondly, the traditional manual inspection method still has certain human errors and subjectivity, which needs to be improved. Utility Model Content

[0028] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 It is a structural schematic diagram of an embodiment of the striking assembly of the utility model; Figure 2 It is a structural schematic diagram of an embodiment of the slapping driving part of the utility model; Figure 3 FIG. 1 is a schematic diagram of the structure of an embodiment of the guide rod of the utility model. Figure 3 As shown, the slapping device includes two slapping plates 5 , two guide rods 1 and a slapping driving unit 3 .

[0030] The first end of each guide rod 1 ( Figure 1 The right end of the substrate (in the middle) can slide through the substrate 2 in the horizontal direction and is connected to a slapping plate 5. The substrate 2 can be fixed to the bottom plate laid at the bottom. Figure 1 The slapping device of the utility model is used to solve how to perform a slapping operation on a homogenizing bag. As for how to slap the homogenizing bag, those skilled in the art can implement it according to common knowledge or existing technology.

[0031] The two guide rods 1 are spaced apart along the width direction of the substrate 2. The second end ( Figure 1 The left end of the slapping plate 5 is connected to the slapping driving unit 3. In the working state, the slapping driving unit 3 can drive the two slapping plates 5 to reciprocate through the two guide rods 1, and then the two slapping plates 5 alternately slap the homogenizing bag.

[0032] In order to better restrict the sliding direction of the two guide rods 1, two guide blocks 4 are provided on the base plate 2. The guide blocks 4 may be provided with through holes. The two guide rods 1 may slidably pass through the through holes of the guide blocks 4 in a one-to-one correspondence. The provision of the guide blocks 4 enables the guide rods 1 to slide in the horizontal direction, thereby restricting the slapping direction of the slapping plate 5, thereby making the slapping process more stable and reliable.

[0033] The slapping driving part 3 may be two cylinders, and the telescopic ends of the two cylinders are extended and retracted alternately, so that the two guide rods 1 and the slapping plate 5 slap the homogenizing bag alternately.

[0034] like Figure 1 and Figure 2 As shown, an optimal embodiment is provided, wherein the slapping driving unit 3 includes a driving wheel 31 and two driven wheels 32 connected by a synchronous belt 33. The driving wheel 31 and the two driven wheels 32 can be pivotally connected to a fixed plate 37. The fixed plate 37 can be connected to the bottom plate through a fixed seat.

[0035] The two driven wheels 32 are both provided with pulleys 34. The pulleys 34 are provided at the edge of the driven wheel 32, that is, away from the axis of the driven wheel 32. The second end of the guide rod 1 is connected with a connecting plate 35. The connecting plate 35 is provided with a slide groove 36, and the slide groove 36 is embedded in the pulley 34. As the driving wheel 31 drives the driven wheel 32 to rotate, the pulley 34 slides relative to the slide groove 36, and under the restriction of the guide block 4, the guide rod 1 and the slap plate 5 reciprocate in the horizontal direction.

[0036] like Figure 1 As shown, the two pulleys 34 can be symmetrical with respect to the center of the midpoint of the axis connecting the two driven wheels 32. Thus, the two guide rods 1 and the clapping plate 5 can be staggered and extended. As an example, if the two driven wheels 32 rotate clockwise, since the two pulleys 34 are symmetrically arranged, the upper ( Figure 1 The driven wheel 32 in the middle direction will drive the guide rod 1 and the slap plate 5 to move to the right. Figure 1 The driven wheel 32 (in the direction of the middle) will drive the guide rod 1 and the clapping plate 5 to move to the left. In this way, the moving directions of the two clapping plates 5 are opposite, thereby realizing the alternating clapping action of the two clapping plates 5.

[0037] like Figure 2 As shown, a driving motor 38 is disposed on the fixing plate 37, and the output shaft of the driving motor 38 passes through the fixing plate 37 and is connected to the driving wheel 31. The driving motor 38 can drive the driving wheel 31 so that the synchronous belt 33 drives the two driven wheels 32 to rotate. As an example, the driving motor 38 can be a servo motor.

[0038] The above-mentioned embodiment of the utility model drives two clapping plates 5 to reciprocate in the horizontal direction through a driving motor 38, and at the same time, the two clapping plates 5 alternately clap the homogenizing bag. Compared with the common method of using two driving motors 38, this implementation method can reduce the manufacturing cost.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
