[0031] See also Figures 1 to 3 The embodiment of the utility model provides a sleeve 7 opening device, which includes: a sleeve jig 1 and a cutting blade 2. The sleeve jig 1 is provided with a through hole 11, and the through hole 11 is used to pass the sleeve 7. The sleeve jig 1 is also provided with a knife slot 12, and the knife slot 12 is connected to the through hole 11. The cutting blade 2 is inserted into the knife slot 12 and one end extends into the through hole 11. When the sleeve 7 passes through the through hole 11, the cutting blade 2 cuts the sleeve 7 from the side wall. It should be explained that when the sleeve 7 passes through the through hole 11, the cutting blade 2 only cuts into the tube wall of the sleeve 7 once, so that one side of the tube wall is cut to produce an opening, and the entire sleeve 7 is not cut to divide it into two. Specifically, the knife slot 12 has at least two openings, one opening is connected to the through hole 11, and the other opening is located on the outer surface of the sleeve jig 1, so that the cutting blade 2 can be inserted into the through hole 11 from the outside of the sleeve jig 1 through the knife slot 12.

[0032] Optionally, the fixed sleeve 7 in this embodiment is a closed sleeve 7. The worker inserts the sleeve 7 from one end of the perforation 11 and then pulls it out from the other end of the perforation 11. When the sleeve 7 moves in the perforation 11, the cutting blade 2 continuously cuts the tube wall of the sleeve 7, so that it changes from a closed sleeve 7 to an open sleeve 7. Therefore, when the order demand for the open sleeve 7 is small, it is not necessary to purchase it from the brand original factory according to the minimum order quantity. The purchased closed sleeve 7 can be processed by the sleeve 7 opening device of this embodiment to obtain an open sleeve 7. The processing quantity can be set according to the order demand, avoiding the inventory material backlog caused by purchasing two types of sleeves 7 at the same time.

[0033] In one embodiment, the sleeve jig 1 is a rectangular metal part, the through hole 11 is a circular hole opened at the central axis of the sleeve jig 1, the inserting knife groove 12 is a through groove extending radially upward along the through hole 11, and the setting length of the inserting knife groove 12 is the same as the setting length of the through hole 11. Specifically, the slot width of the inserting knife groove 12 is greater than or equal to the thickness of the cutting blade 2. Specifically, the sleeve jig 1 is an integrated structure. Specifically, the sleeve jig 1 is a symmetrical structure, and further, the sleeve jig 1 is a left-right symmetrical structure. Specifically, the through hole 11 is a straight hole opened along the axial direction of the sleeve jig 1.

[0034] Furthermore, a guide groove 13 is provided at the opening of one end of the through hole 11, and the opening of the guide groove 13 gradually becomes larger and trumpet-shaped in the direction away from the through hole 11, so that the guide groove 13 can guide the sleeve 7 to automatically align and smoothly enter the through hole 11, which reduces the difficulty of operation and improves work efficiency.

[0035] In one embodiment, the through hole 11 has two openings at two ends, namely an inlet and an outlet, and the guide groove 13 is disposed at the inlet of the through hole 11 .

[0036] Further, in order to ensure that the sleeve 7 passes smoothly through the through hole 11, the diameter of the through hole 11 is greater than or equal to the diameter of the sleeve 7. Preferably, the diameter of the through hole 11 is greater than the diameter of the sleeve 7.

[0037] Furthermore, the sleeve 7 opening device also includes at least two positioning members 3, which are penetrated through the two side groove walls of the knife slot 12 and the cutting blade 2, so that there are at least two connection points between the cutting blade 2 and the groove wall of the knife slot 12, so that the cutting blade 2 cannot be displaced or rotated in the knife slot 12.

[0038] Specifically, the positioning member 3 is detachably connected to the casing jig 1, that is, the casing jig 1 is provided with first positioning holes having the same number as the positioning member 3, and the cutting blade 2 is provided with second positioning holes having the same number as the positioning member 3. When the positioning member 3 is inserted into the first positioning hole and the second positioning hole, the cutting blade 2 is relatively fixed to the casing jig 1; the positioning member 3 is removed, and the cutting blade 2 is separated from the casing jig 1. In one embodiment, the width of the blade insertion groove 12 can also be made smaller than the thickness of the cutting blade 2, and the cutting blade 2 can be inserted into the blade insertion groove 12 by external force, and the casing jig 1 and the cutting blade 2 can be relatively fixed by the squeezing force of the groove wall of the blade insertion groove 12. In this embodiment, the number of the positioning members 3 is two, and correspondingly, the number of the first positioning holes is two, and the number of the second positioning holes is two.

[0039] In one embodiment, the middle of the first positioning hole is connected to the blade insertion groove 12, and the inner wall of the first positioning hole is provided with an internal thread, and the positioning member 3 is provided with an external thread matching the internal thread, and the positioning member 3 is screwed with the sleeve fixture 1, so that the positioning member 3 can position the cutting blade 2 more stably. Optionally, the positioning member 3 is a screw.

[0040] Furthermore, in order to enable the cutting blade 2 to cut into the sleeve 7 more effectively, reduce the time and force required for cutting, and thus improve production efficiency, the angle between the cutting blade 2 and the central axis of the perforation 11 in this embodiment is greater than 20 degrees and less than 80 degrees. Preferably, the end of the cutting blade 2 extending into the perforation 11 is inclined toward the travel direction of the sleeve 7, and the angle between the cutting blade 2 and the central axis of the perforation 11 is 45 degrees.

[0041] Furthermore, in order to fix the sleeve jig 1 to the external workbench, the sleeve 7 opening device of this embodiment also includes a fixing clamp 4, and there is a gap between the two ends of the fixing clamp 4. The sleeve jig 1 is clamped in the gap. During operation, the sleeve jig 1 only needs to be clamped into the gap, and the fixing clamp 4 can provide stable support to prevent the sleeve jig 1 from moving or shaking during operation.

[0042] Specifically, in order to enhance the applicability of the sleeve jig 1 in different environments, the sleeve 7 opening device also includes a fixing member 5, and a threaded hole is provided at one end of the fixing clamp 4, and the fixing member 5 is screwed into the threaded hole. When the fixing member 5 is rotated, the fixing member 5 will extend into or out of the gap. It should be explained that when the fixing member 5 is rotated and extends into the gap, the sleeve jig 1 will be located between the other end of the fixing clamp 4 and the fixing member 5. The more the fixing member 5 extends into the gap, the smaller the gap between the fixing member 5 and the other end of the fixing clamp 4 will be, so that the sleeve jig 1 is clamped between the fixing member 5 and the other end of the fixing clamp 4. It can be understood that, generally, the fixing member 5 and the other end of the fixing clamp 4 include the sleeve jig 1 and the external workbench, and the staff can adjust the fixing member 5 according to actual needs to tightly clamp the sleeve jig 1 and the external workbench between the fixing member 5 and the other end of the fixing clamp 4.

[0043] Furthermore, in order to make the fixing member 5 rotate more conveniently and labor-savingly, a rotating rod 6 is provided on the fixing member 5 . Preferably, the rotating rod 6 is perpendicular to the central axis of the fixing member 5 .

[0044] Compared with the prior art, in the casing opening device of the utility model, when the casing passes through the perforation, the cutting blade will cut through the tube wall of the casing, thereby realizing the conversion of the closed casing into an open casing.

[0045] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
