[0003] In the prior art, in order to facilitate the packaging of wear-resistant balls, a packaging bag is usually placed below the tail end of the grinding ball conveyor, so that when the grinding balls are transported to the tail end by the conveyor, the packaging bag can effectively receive the grinding balls from below the tail end of the conveyor;

[0004] However, most of the existing grinding ball packaging bags are made of cloth and have a certain flexibility. Without external force support, their openings are extremely prone to bending deformation. Therefore, during actual grinding ball packaging, it is necessary for workers to pull the opening of the packaging bag for a long time to shape the opening of the packaging bag. The actual operation is generally time-consuming and laborious, and seriously affects the work efficiency of manual operations. Content of the Utility Model

[0005] To solve the above technical problems, an opening bracket for assisting in grinding ball bagging is provided, which solves the problem that most of the existing grinding ball packaging bags are made of cloth and have a certain flexibility. Without external force support, their openings are extremely prone to bending deformation. Therefore, during actual grinding ball packaging, it is necessary for workers to pull the opening of the packaging bag for a long time to shape the opening of the packaging bag. The actual operation is generally time-consuming and laborious, and seriously affects the work efficiency of manual operations.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: an opening bracket for assisting in grinding ball bagging, including a carrier plate, a semi-circular notch is provided on one side of the carrier plate, a mouth-fixing part is arranged above the semi-circular notch, a supporting part is arranged outside the carrier plate, and a clamping part is arranged above the carrier plate;

[0007] The mouth-fixing part includes a shaping ring arranged in a ring shape above the semi-circular notch and a support plate fixed between the shaping ring and the carrier plate;

[0008] The clamping part includes two clamping plates symmetrically and slidably arranged on both sides of the shaping ring respectively and a connecting plate fixed to the bottom end of the clamping plate. The bottom end of the connecting plate is fixed with a movable plate slidably connected to the top surface of the carrier plate, and an extrusion assembly is arranged between the two movable plates.

[0009] Preferably, the supporting part includes two groups of bracket groups symmetrically arranged on both sides of the carrier plate. Each bracket group consists of two legs distributed in a mirror image. The top ends of the legs are fixedly connected to the side walls of the carrier plate, and several C-shaped reinforcing ribs are fixed between the four legs.

[0010] Preferably, the extrusion assembly includes a push-pull plate slidably arranged above the carrier plate and extrusion rods fixed to both ends of the push-pull plate. A pressure-receiving groove with a right-angled trapezoidal cross-section is formed in the inner wall of the movable plate. The end of the extrusion rod is elliptical and penetrates into the pressure-receiving groove, and the elliptical end of the extrusion rod abuts against the inclined inner wall of the pressure-receiving groove.

[0011] Preferably, the extrusion assembly further includes a transmission screw rod threadedly penetrating through the middle of the push-pull plate, and one end of the transmission screw rod is rotatably connected to the outer wall of the support plate.

[0012] Preferably, a T-shaped slider is fixed to the bottom end of the movable plate, a sliding slot adapted to the slider is formed on the top surface of the carrier plate, and a return spring is fixed between the slider and one inner wall of the sliding slot.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] (1) Through the arrangement of the carrier plate and the fixed mouth part, when the grinding balls are to be bagged, the packaging bag is pre-placed inside the semi-circular notch, and then its opening is turned outwards and placed on the shaping ring. In this way, the shaping ring is used to stably shape the opening of the packaging bag instead of manual operation, so as to prevent the opening of the packaging bag from bending and deforming, which affects the material receiving effect.

[0015] (2) Through the arrangement of the clamping part, after the opening of the packaging bag is turned outwards and placed on the shaping ring, the extrusion assembly in the clamping part is used to make the movable plate under the two clamping plates slide towards each other on the top surface of the carrier plate until the clamping plates are clamped on the outer periphery of the shaping ring. In this way, the fixing effect of the opening of the packaging bag on the shaping ring can be further enhanced, making it difficult for the opening of the packaging bag to break away from the shaping ring, and improving the practicability.

[0021] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0022] Referring to Figures 1 - 3 As shown, an opening bracket for assisting in bagging grinding balls includes a carrier plate 1. A semi-circular notch is formed on one side of the carrier plate 1. A mouth-fixing part is arranged above the semi-circular notch, and a support part is arranged outside the carrier plate 1.

[0023] The mouth-fixing part includes a shaping ring 2 arranged in a ring shape above the semi-circular notch and a support plate 3 fixed between the shaping ring 2 and the carrier plate 1.

[0024] Through the arrangement of the carrier plate 1 and the mouth-fixing part, when bagging grinding balls, the packaging bag is pre-placed inside the semi-circular notch, and then its opening is turned outwards and placed on the shaping ring 2, so as to use the shaping ring 2 to stably shape the opening of the packaging bag instead of manual labor, so as to prevent the opening of the packaging bag from bending and deforming, affecting the material receiving effect.

[0025] Furthermore, referring to Figure 1 As shown, it should be noted that the support part includes two support groups symmetrically arranged on both sides of the carrier plate 1 respectively. Each support group is composed of two support legs 4 distributed mirror-symmetrically. The top ends of the support legs 4 are fixedly connected to the side walls of the carrier plate 1, and a number of C-shaped reinforcing ribs 5 are fixed between the four support legs 4.

[0026] Through the arrangement of the support part, the overall stability of the carrier plate 1, the shaping ring 2 and the support plate 3 can be effectively supported from the outside, and a reasonable interval is reserved between the carrier plate 1 and the ground, so as to facilitate the vertical placement of the packaging bag.

[0027] Furthermore, referring to Figures 1 - 3 As shown, it should be noted that a clamping part is arranged above the carrier plate 1;

[0028] The clamping part includes two clamping plates 6 symmetrically and slidably arranged on both sides of the shaping ring 2 respectively and a connecting plate 7 fixed to the bottom ends of the clamping plates 6. The bottom end of the connecting plate 7 is fixed with a movable plate 8 slidably connected to the top surface of the carrier plate 1. An extrusion assembly is arranged between the two movable plates 8;

[0029] Through the setting of the clamping part, after turning the opening of the packaging bag outwards and mounting it on the shaping ring 2, the extrusion component in the clamping part is used to act on the movable plate 8 below the two clamping plates 6 to slide towards each other on the top surface of the carrier plate 1 until the clamping plates 6 are clamped on the outer periphery of the shaping ring 2, so as to further enhance the fixing effect of the packaging bag opening on the shaping ring 2, making it difficult for the packaging bag opening to break away from the shaping ring 2 and improving the practicability.

[0030] Furthermore, referring to Figure 1 As shown, it is worth noting that the extrusion component includes a push-pull plate 11 slidably arranged above the carrier plate 1 and extrusion rods 10 fixed to both ends of the push-pull plate 11. A pressure-receiving groove 9 with a right-angled trapezoidal cross-section is formed in the inner wall of the movable plate 8. The end of the extrusion rod 10 is elliptical and penetrates into the pressure-receiving groove 9, and the elliptical end of the extrusion rod 10 abuts against the inclined inner wall of the pressure-receiving groove 9;

[0031] The extrusion component further includes a transmission screw rod 12 threaded through the middle end of the push-pull plate 11, and one end of the transmission screw rod 12 is rotatably connected to the outer wall of the support plate 3;

[0032] Through the setting of the extrusion component, turning the transmission screw rod 12, that is, acting on the push-pull plate 11 to slide along the rod body of the transmission screw rod 12 by the thread structure, so that the extrusion rod 10 penetrates into the inner side of the pressure-receiving groove 9 and continuously presses the inclined inner wall of the pressure-receiving groove 9, forming a thrust on the whole movable plate 8, connecting plate 7 and clamping plate 6, and acting on the clamping plate 6 to be clamped on the outer periphery of the shaping ring 2, realizing the fixing effect on the packaging bag opening.

[0033] Furthermore, referring to Figure 1 and Figure 2 As shown, it is worth noting that a T-shaped slider 13 is fixed to the bottom end of the movable plate 8, a sliding groove 14 adapted to the slider 13 is formed on the top surface of the carrier plate 1, and a return spring 15 is fixed between the slider 13 and the inner wall of one side of the sliding groove 14;

[0034] Through the setting of the slider 13, sliding groove 14 and return spring 15, when the extrusion rod 10 penetrates into the inner side of the pressure-receiving groove 9 to form an extrusion effect on the movable plate 8 and the movable plate 8 drives the clamping plate 6 to slide towards the shaping ring 2, the slider 13 can slide synchronously inside the sliding groove 14 during this process. With the cooperation of the two, the movement track of the movable plate 8, connecting plate 7 and clamping plate 6 can be limited, and during this process, the slider 13 continuously presses the return spring 15 to deform. Using the elastic force of the return spring 15, when the transmission screw rod 12 is turned in the reverse direction and the extrusion rod 10 withdraws from the inner side of the pressure-receiving groove 9, and the extrusion force on the movable plate 8 is reduced, the movable plate 8, connecting plate 7 and clamping plate 6 as a whole can be quickly reset, releasing the fixing of the packaging bag opening on the shaping ring 2 and facilitating the manual taking of the packaging bag.
