Description

Technical Field

[0001] The present invention belongs to the technical field of plastic part processing, and more specifically, relates to an assembled grain strip and a manufacturing method thereof. Background Art

[0002] Non-standard plastic parts are usually manufactured by processing methods such as extrusion, injection molding, and cutting. Among them, the parts manufactured by extrusion must have the same shape in the relative radial direction. For plastic parts with large injection-molded sizes, higher requirements are imposed on injection equipment and molds. For plastic parts processed by cutting, after processing, the internal stress is released, resulting in large deformations. For plastic materials, the current manufacturing processes cannot produce high-precision parts with extremely long lengths. Therefore, there is an urgent need for a technical solution in the prior art that can process high-precision plastic parts with relatively long lengths. Summary of the Invention

[0003] In view of the above deficiencies in the prior art, the present invention provides an assembled grain strip that can meet the needs of extremely long parts and has high precision, as well as a manufacturing method thereof.

[0004] To achieve the above object, the present invention is realized through the following technical solutions:

[0005] An assembled grain strip includes a grain plate, and the grain plate includes an upper grain plate and a lower grain plate that are buckled with each other up and down. Both sides of the upper grain plate are provided with upper grain plate through grooves, both sides of the lower grain plate are provided with lower grain plate through grooves, the upper grain plate is provided with upper grain holes, the lower grain plate is provided with lower grain holes, and the upper grain holes and the lower grain holes are vertically communicated;

[0006] Both sides of the grain plate are provided with end plates, and the end plates include an upper end plate and a lower end plate. Both sides of the upper end plate have upper end plate through grooves, both sides of the lower end plate have lower end plate through grooves, and a serrated groove is provided inside the lower end plate through groove;

[0007] A side bar is penetrated through the upper end plate through groove, the lower end plate through groove, the upper grain plate through groove, and the lower grain plate through groove, and a tooth alveolar groove that meshes with the serrated groove is provided on the lower side of the side bar.

[0008] The total length of the lower end plate through groove and the lower grain plate through groove is the same as the length of the side bar.

[0009] The sum of the widths of the upper grain plate through groove and the lower grain plate through groove, and the sum of the widths of the upper end plate through groove and the lower end plate through groove are both the same as the width of the side bar.

[0010] The thicknesses of the upper end plate through groove, the lower end plate through groove, the upper grain plate through groove, and the lower grain plate through groove are all the same as the thickness of the side bar.

[0011] The side strip is a steel strip.

[0012] The serrated groove is a square groove, the tooth alveolar groove is a trapezoidal groove, and the distance between the trapezoidal grooves is shorter than the width of the square groove.

[0013] The present invention also provides another technical solution, and the specific content is as follows:

[0014] A manufacturing method of an assembled grain counting strip, comprising the following steps:

[0015] (1) Processing a plurality of upper grain counting plates, lower grain counting plates, two upper end plates and two lower end plates by an injection molding method;

[0019] The beneficial effects of the present invention compared with the prior art are as follows: The grain counting strip is formed by sequentially connecting a plurality of grain counting plates end to end, and a grain counting strip with an extremely long length can be manufactured. The grain counting strip has grain counting holes for allowing granular medicines or foods such as pills to pass through one by one. The grain counting strip can be lengthened as required as much as possible, and is no longer limited by the low machining accuracy and easy deformation of large-sized plastic parts.

Detailed implementation manner

[0029] As Figure 1-8 shown, the assembled grain counting bar includes a grain counting plate 2, and the grain counting plate 2 includes an upper grain counting plate 1 and a lower grain counting plate 3 that are buckled up and down with each other. Upper grain counting plate through grooves 11 are provided on both sides of the upper grain counting plate 1, lower grain counting plate through grooves 5 are provided on both sides of the lower grain counting plate 3, upper grain counting holes 7 are provided on the upper grain counting plate 1, lower grain counting holes 8 are provided on the lower grain counting plate 3, and the upper grain counting holes 7 and the lower grain counting holes 8 communicate with each other up and down;

[0030] End plates 4 are provided on both sides of the grain counting plate 2. The end plates 4 include an upper end plate 9 and a lower end plate 10. Upper end plate through grooves 12 are provided on both sides of the upper end plate 9, lower end plate through grooves 13 are provided on both sides of the lower end plate 10, and serrated grooves 14 are provided inside the lower end plate through grooves 13;

[0031] A side bar 6 is penetrated through the upper end plate through groove 12, the lower end plate through groove 13, the upper grain counting plate through groove 11 and the lower grain counting plate through groove 5. A tooth alveolar groove 15 that meshes with the serrated groove 14 is provided on the lower side of the side bar 6.

[0032] The total length of the lower end plate through groove 13 and the lower grain counting plate through groove 5 is the same as the length of the side bar 6.

[0033] The sum of the widths of the upper grain counting plate through groove 11 and the lower grain counting plate through groove 5, and the sum of the widths of the upper end plate through groove 12 and the lower end plate through groove 13 are both the same as the width of the side bar 6.

[0034] The thicknesses of the upper end plate through groove 12, the lower end plate through groove 13, the upper grain counting plate through groove 11 and the lower grain counting plate through groove 5 are all the same as the thickness of the side bar 6.

[0035] The side bar 6 is a slender strip-shaped steel belt and is formed by laser cutting.

[0036] The serrated groove 14 is a square groove, the tooth alveolar groove 15 is a trapezoidal groove, and the distance between the trapezoidal grooves is shorter than the width of the square groove.

[0037] The manufacturing method of the above-mentioned assembled grain counting bar includes the following steps:

[0038] (1) Process a plurality of upper counting plates 1, lower counting plates 3, two upper end plates 9 and two lower end plates 10 by injection molding. The number of upper counting plates 1 is the same as that of lower counting plates 3, and the specific number is determined according to the required length of the counting strip;

[0039] (2) Arrange a plurality of lower counting plates 3 neatly in a "one" shape, and place the two lower end plates 10 on the outer sides of the lower counting plates 3 at both ends, that is, on the left side of the leftmost counting plate 2 and on the right side of the rightmost counting plate 2;

[0040] (3) Insert the side strip 6 into the lower counting plate through groove 5 and the lower end plate through groove 13, and make the tooth alveolar groove 15 on the lower side of the side strip 6 engage with the sawtooth groove 14 in the lower end plate through groove 13; the tooth alveolar grooves 15 on the left and right sides below the side strip 6 are trapezoidal grooves, and the sawtooth grooves 14 in the lower end plate through groove 13 are square grooves. The distance between the trapezoidal grooves is slightly shorter than the width of the square groove, so that the trapezoidal grooves can be stuck into the square grooves;

[0041] (4) Snap the upper counting plate 1 onto the lower counting plate 3, and snap the upper end plate 9 onto the lower end plate 10. Each lower counting plate 3 corresponds to an upper counting plate 1, and each lower end plate 10 corresponds to an upper end plate 9. Since the sum of the widths of the upper counting plate through groove 11 and the lower counting plate through groove 5, and the sum of the widths of the upper end plate through groove 12 and the lower end plate through groove 13 are both the same as the width of the side strip 6, therefore, press the upper counting plate 1 and the upper end plate 9 so that the side strip 6 just snaps into the upper end plate through groove 12 and the upper counting plate through groove 11; since the distance between the trapezoidal grooves is slightly shorter than the width of the square groove, during the pressing process, the plastic material undergoes a slight deformation, pressing the upper end plate 9 to ensure the straightness of the overall lengthened counting strip; there are ultrasonic welding lines and melting grooves left between the upper end plate through groove 12 and the lower end plate through groove 13, and between the upper counting plate through groove 11 and the lower counting plate through groove 5. Then use an ultrasonic welding machine to weld each group of upper counting plates 1 and lower counting plates 3 into a sealed whole, and weld each group of upper end plates 9 and lower end plates 10 into a whole.

[0042] The upper counting holes 7 on the upper counting plate 1 are aligned with the lower counting holes 8 on the lower counting plate 3 one by one and penetrate up and down, so that granular medicines or foods such as pills can pass through one by one, completing the function of the counting strip. The above-mentioned assembled counting strip is spliced by a plurality of counting plates 2 and end plates 4 at both ends. Processing a single counting plate 2 alone can ensure the processing accuracy and avoid the problems such as low processing accuracy caused by directly processing a counting strip part with too long dimensions. The end plate 4 is designed as a hollow structure, which can save plastic materials.

[0043] The above is only the preferred embodiment of the present invention, but the present invention is not limited to the above specific embodiments. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
