Description

TECHNICAL FIELD

[0002] The filling of emulsion explosive is the core process in the production of emulsion explosive, which is to fill the bulk explosive into cartridges according to specifications after the preparation is completed, and then to buckle and seal the two ends of the cartridge through a carding device to prevent the leakage of the explosive material. However, the existing carding device has some problems in actual application. First, the storage capacity of the buckle disc is small, and it can only maintain continuous feeding for 3-4 hours when processing small-diameter cartridges, so the replacement frequency of the buckle disc is too high, which requires the operator to frequently enter the production line to replace the buckle disc, not only increasing the labor cost, but also significantly increasing the exposure risk of personnel due to the high-risk nature of the emulsion explosive production line. In addition, the frequent disc replacement operation also causes the residual buckles in the buckle disc to be not fully utilized, increasing the waste of materials. In addition, the buckles will rub against the pipe wall of the feeding port during transportation, which can cause wear, deformation or even breakage of the buckle surface, greatly affecting the sealing accuracy of the cartridge, leading to length error of the cartridge exceeding the standard, and further causing problems such as unqualified product weight.

DETAILED DESCRIPTION

[0018] The technical scheme of the utility model will be further illustrated below with reference to the drawings and specific embodiments.

[0019] The buckle feeding device of the emulsion explosive filling machine in the embodiment is shown in Fig. 1, which comprises a buckle feeding assembly 1. Figures 1-3 The buckle feeding assembly 1 comprises a buckle disc 11, a limiting support 12, a base 13 and a feeding structure 14. The buckle disc 11 is rotatably fixed on the base 13 through the limiting support 12. The feeding structure 14 comprises a vertical pipe section 141, a guide pipe section 142 and a feeding port 143. The vertical pipe section 141 is arranged on the base 13 and extends below the base 13. One end of the guide pipe section 142 is connected with the vertical pipe section 141, and the other end of the guide pipe section 142 is provided with the feeding port 143. The feeding port 143 is arranged in the tangential direction of the buckle disc 11. The feeding port 143 has a gradually narrowing curved surface. The outer diameter of the buckle disc 11 is 3-5 times the diameter of the inner shaft of the buckle disc 11.

[0020] By increasing the outer diameter of the buckle disc 11 to 3-5 times the diameter of the inner shaft of the buckle disc 11, the storage capacity of the buckle disc 11 for buckles is increased, and the frequency of replacing the buckle disc 11 is reduced, thereby reducing the number of times that the operator enters the emulsion explosive production line and reducing the risk coefficient to meet the requirements of safety regulations. At the same time, the waste of buckles caused by frequent replacement of the chuck is avoided, and the cost is reduced. By providing the feeding port 143 with a gradually narrowing curved surface, the friction between the buckle and the feeding port 143 is reduced, the risk of buckle disconnection is reduced, and the accuracy of buckle positioning is improved.

[0021] Preferably, the surface of the feeding port 143 is provided with a wear-resistant layer, which can be made of polytetrafluoroethylene material. By providing the surface of the feeding port 143 with a wear-resistant layer, the friction coefficient of the surface of the feeding port 143 is reduced, thereby effectively avoiding the surface wear of the buckle caused by the friction between the buckle and the surface of the feeding port 143. This helps to maintain the original shape and size accuracy of the buckle, thereby further improving the sealing quality of the cartridge, reducing the problems of loose sealing and cartridge length error caused by buckle wear, and improving the qualification rate of the product.

[0022] Preferably, the curvature radius of the curved surface at the feeding port 143 is R=5-8mm. By setting the appropriate curvature, the possibility of jamming, easy to appear jam or deviation from the transport path, further reducing the possibility of wear, deformation or even breakage of the buckle surface, better guarantee the integrity and quality of the buckle, and further improve the sealing precision of the cigarette and the product quality.

[0023] Preferably, the included angle between the guide pipe section 142 and the vertical pipe section 141 is 130°-150°. Since the buckle will be subjected to a greater friction force at the turning of the feeding structure 14, by setting the included angle between the guide pipe section 142 and the vertical pipe section 141 to be 130°-150°, the buckle is more smoothly into the vertical pipe section 141, reducing the surface wear, deformation or breakage caused by excessive friction and collision.

[0024] Preferably, the limiting support 12 includes a fixed seat 121 and two sets of limiting roller shafts 122, the fixed seat 121 is arranged on the base 13, the two sets of limiting roller shafts 122 are arranged in front of and behind each other, the end of the limiting roller shaft 122 is rotatably connected with the fixed seat 121, the buckle disc 11 is arranged between the two sets of limiting roller shafts 122, and the two sets of limiting roller shafts 122 are in sliding fit with the outer side of the buckle disc 11.

During the rotation of the buckle disc 11, the limiting roller shaft 122 plays a limiting role on the buckle disc 11, so that the buckle disc 11 is fixed on the base 13 and always keeps a stable rotating state, ensuring that the buckle can continuously and stably enter the feeding structure 14 from the buckle disc 11, improving the working stability. When it is necessary to replace the buckle disc 11, it can be installed or disassembled by taking out or putting in the buckle disc 11 between the two sets of limiting roller shafts 122, improving the efficiency of replacing the buckle disc 11 and reducing the residence time of the operator on the production line.

[0026] Preferably, the limiting roller shaft 122 is further provided with a limiting baffle 123 at both ends, and the inner side of the limiting baffle 123 is in close contact with the outer side of the buckle disc 11. By setting the limiting baffle 123 at the end of the limiting roller shaft 122 in close contact with the outer side of the buckle disc 11, the limiting baffle 123 plays a role in limiting the axial direction of the buckle disc 11, ensuring that the buckle disc 11 is fixed on the base 13.

[0027] Preferably, the buckle feeding assembly 1 is multiple groups, the multiple groups of buckle feeding assemblies 1 are uniformly distributed on the outer periphery above the rotating disc 2, the positioning assembly 3, the carding assembly 4 and the cutter assembly 5 are all arranged below the rotating disc 2, the positioning assembly 3 is used for grabbing the buckle of a set length to the carding assembly 4, the carding assembly 4 is used for carding the cartridge case and cutting the cartridge case into segments, and the cutter assembly 5 is used for cutting the cartridge case after carding.
