Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder packaging, in particular to a ton bag inner bag restraint tooling. Background Art
[0002] Graphite and other industrial raw materials are often packaged in ton bags. During packaging, a plastic bag is placed inside the ton bag to avoid powder contamination. During the feeding process, a restraining ring or a mechanism that can open and close is usually used to tighten the mouth of the plastic bag to avoid powder contamination. However, the tightening mechanism currently used has a general tightening effect on plastics, and powders are prone to overflow during the feeding process. Of course, the mouth of the plastic bag needs to be connected to the external environment to avoid affecting the feeding. Utility Model Content
[0003] The utility model provides a ton bag inner bag restraint tooling to solve the above-mentioned deficiencies in the prior art and the problem of powder material pollution caused by poor sealing effect of plastic bags, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:
[0005] A ton bag inner bag restraint tooling includes a tank body, the lower end of the tank body is connected with a discharge pipe, the lower end of the discharge pipe is symmetrically mounted with a pair of mounting blocks, the outer end of the mounting block is provided with an extension plate, a pair of guide holes are opened on the extension plate, a movable rod is passed through the guide hole, an upper movable plate is provided at the upper end of the movable rod, a pair of guide rods are passed through the upper movable plate, the guide rods are arranged on the mounting block, a lower movable plate is installed at the lower end of the movable rod, a mounting platform is installed at the lower end of the lower movable plate, a restraining arc plate is provided at the inner side end of the mounting platform, an inner top plate is provided on the outer wall of the upper movable plate, an inclined surface is provided on the outer wall of the inner top plate, a hinged head is provided at the upper end of the mounting block, a concave plate is hinged on the hinged head, a pressure rod is provided in the concave plate, and the outer periphery of the pressure rod is tangent to the outer wall of the inner top plate. The pressure rod can act on the outer wall of the inner top plate, thereby causing the upper movable plate and the restraining arc plate to move inward, thereby restraining the bag mouth of the plastic bag through the restraining arc plate.
[0006] Furthermore, a spring is sleeved on the guide rod, and the spring is located between the mounting block and the upper movable plate. The arrangement of the spring can cancel the restraining effect of the restraining arc plate when the pressure rod cancels its effect.
[0007] Furthermore, a waist-shaped hole is provided on the horizontal section of the concave plate, and the two ends of the pressure rod are inserted into the waist-shaped hole. The two ends of the pressure rod are provided with movable concave parts, which are sleeved on the outer end of the concave plate. The outer end of the movable concave part is screwed with an adjusting screw rod, and the outer end of the adjusting screw rod is provided with a holding head. The adjusting screw rod is rotated to make the pressure rod press against the outer wall of the inner top plate, thereby ensuring the reliability after the constraint.
[0008] Furthermore, an inner ring is provided on the outer circumference of the discharge pipe, an inner groove is opened on the inner circumference of the constraining arc plate, and the inner ring passes through the inner groove. The inner ring and the inner groove can enhance the constraint and sealing effects.
[0009] Furthermore, the inner ring is in an isosceles trapezoidal structure, the inner embedded groove is in an isosceles trapezoidal structure, and the inner wall of the inner embedded groove is provided with a soft layer to prevent the plastic bag from being damaged during the restraint process.
[0010] The advantages of the above technical solution are:
[0011] The utility model facilitates the restraining operation of the bag mouth of the plastic bag and improves the restraining effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1~Figure 4 As shown, a ton bag inner bag restraint tooling comprises a tank body 1, the lower end of the tank body 1 is connected with a discharge pipe 10, the lower end of the discharge pipe 10 is symmetrically mounted with a pair of mounting blocks 2, the outer end of the mounting block 2 is provided with an extension plate 20, the extension plate 20 is provided with a pair of guide holes 21, movable rods are passed through the guide holes 21, the upper ends of the movable rods are provided with an upper movable plate 25, the upper movable plate 25 is passed through with a pair of guide rods 23, the guide rods 23 are sleeved with springs 24, the springs 24 are located between the mounting block 2 and the upper movable plate 25, the guide rods 23 are arranged on the mounting block 2, the lower end of the movable rods is mounted with a lower movable plate 34, the lower end of the lower movable plate 34 is mounted with a mounting platform 35, and the inner end of the mounting platform 35 is provided with a restraining arc plate 36. An inner ring 39 is provided on the outer periphery of the discharge pipe 10, and an inner groove is provided on the inner periphery of the constraining arc plate 36. The inner ring 39 passes through the inner groove. The inner ring 39 is an isosceles trapezoidal structure, the inner groove is an isosceles trapezoidal structure, and a soft layer is provided on the inner wall of the inner groove.
[0018] The outer wall of the upper movable plate 25 is provided with an inner top plate 22, and the outer wall of the inner top plate 22 is provided with an inclined surface. The upper end of the mounting block 2 is provided with a hinge head 26, and a concave plate 27 is hinged on the hinge head 26. A pressure rod 29 is provided in the concave plate 27, and the outer periphery of the pressure rod 29 is tangent to the outer wall of the inner top plate 22. A waist-shaped hole 28 is opened on the horizontal section of the concave plate 27, and both ends of the pressure rod 29 are passed through the waist-shaped hole 28. Both ends of the pressure rod 29 are provided with a movable concave member 32, and the movable concave member 32 is sleeved on the outer end of the concave plate 27. The outer end of the movable concave member 32 is screwed with an adjusting screw rod 30, and the outer end of the adjusting screw rod 30 is provided with a holding head 31.
[0019] When operating the present embodiment, the operator inserts the bag mouth of the plastic bag into the lower end of the discharge pipe 10 .
[0020] Then the operator rotates the concave plate 27 downward, and when the concave plate 27 rotates downward, the pressure rod 29 will act on the outer wall of the inner top plate 22, so that the upper movable plate 25 and the constraint arc plate 36 at its lower end move inward, so that the upper end of the plastic bag is constrained and limited by the constraint arc plate 36. During the process of constraint and limitation, the plastic bag will be constrained in the inner ring 39 and the embedded groove, and in order to facilitate ventilation, the smaller position at the upper end of the packaging bag can be made not to be constrained. And when the constraint is completed, the spring 24 will also be compressed, and then when the constraint is completed, the elastic force generated by the spring 24 and the internal top force of the pressure rod 29 make it reach a balanced state at this time, thereby ensuring the stability after the constraint. Of course, the constraint effect on the plastic bag can also be further improved by rotating the adjustment screw 30.
