The inner wall of the feeding bucket 1 is provided with a quantitative mechanism 2, and both sides of the outer wall of the feeding bucket 1 are fixedly connected with a support frame 3, and two groups of support frames 3 are fixedly connected with a guide frame 4 at one end away from the feeding bucket 1. By providing two groups of support frames 3, the feeding bucket 1 and the guide frame 4 can be fixedly connected in series. The inner wall of the guide frame 4 is provided with a feeding component 7, and the bottom end of the outer wall of the feeding bucket 1 is fixedly connected with a telescopic hose 5. The telescopic hose 5 is a prior art and has its own telescopic line, so that the feeding head 75 automatically retracts and retracts when following the slider 73 to move back and forth. The outer wall of the guide frame 4 is fixedly connected with four groups of mounting feet 6. By providing four groups of mounting feet 6, the overall matching bolts can be connected to the machine where the material needs to be fed, so that the plastic additive can be conveniently fed into the machine.

[0034] Reference Figure 2 - Figure 4 The quantitative mechanism 2 includes a moving rod 21, and the bottom end of the outer wall of the moving rod 21 is fixedly connected to a positioning block A22. The surface of the positioning block A22 is provided with an inclined surface, which facilitates the plastic additives falling on its surface to be discharged outward along the inclined surface. The outer wall of the top of the moving rod 21 is fixedly connected to a connecting rod 25. In the process of moving up and down, the connecting rod 25 will drive the moving rod 21 to move up synchronously with it, and the rising position of the moving rod 21 is guided by the connecting rod 25. A slide groove is provided on the left inner wall of the delivery bucket 1. The connecting rod 25 passes through and is slidably connected to the inner wall of the slide groove of the delivery bucket 1. The inner wall on the left side of the top of the delivery bucket 1 is limited by a spring The spring 26 is elastically connected to the plug block 27. One end of the limit spring 26 is fixedly connected to the inner wall of the top left side of the delivery bucket 1, and the other end of the limit spring 26 is fixedly connected to the surface of the plug block 27. The function of the limit spring 26 is to automatically reset the position of the plug block 27 after it is pulled outward. The plug block 27 passes through and is slidably connected to the inner wall of the top left side of the delivery bucket 1. A plurality of through holes are provided on the surface of the connecting rod 25. The plug block 27 is plugged into the inner wall of the through hole. The plugging between the two fixes the multiple positions of the connecting rod 25 to drive the moving rod 21 and the rotating rod 23 to rise, so that the storage capacity inside the delivery bucket 1 can be adjusted according to actual needs.

[0035] Reference Figure 4The inner wall of the moving rod 21 is elastically connected to the rotating rod 23 through a spiral spring 28. One end of the spiral spring 28 is fixedly connected to the surface of the rotating rod 23, and the other end of the spiral spring 28 is fixedly connected to the inner wall of the top of the moving rod 21. The function of the spiral spring 28 is to automatically reset the position of the positioning block B24 after the rotating rod 23 drives the positioning block B24 to rotate. The rotating rod 23 passes through and is rotatably connected to the inner wall of the moving rod 21. The bottom end of the outer wall of the rotating rod 23 is fixedly connected to the positioning block B24. When the rotating rod 23 rotates, it will drive the positioning block B24 to rotate synchronously, so that the gap on the right half of the positioning block A22 can be opened, thereby allowing the accumulated objects on the positioning block A2 2. The plastic additives on the surface can fall into the telescopic hose 5 along its inclined surface and be released outward from the release head 75. The outer wall of the movable rod 21 contacts the inner side wall of the release bucket 1. The outer wall of the positioning block B24 contacts the inner side wall of the release bucket 1. The top end of the outer wall of the positioning block B24 is rotatably connected to the bottom end of the outer wall of the positioning block A22. The size of the positioning blocks A22 and B24 is only half of the cavity of the inner wall of the release bucket 1. The positioning block B24 is opened at the bottom end of the positioning block A22, so that the plastic additives accumulated on the surfaces of the positioning blocks A22 and B24 can be discharged outward from the inclined surface of the positioning block A22.

[0036] Reference Figure 1 and Figure 5 The delivery assembly 7 includes a servo motor 71, the output shaft of the servo motor 71 is fixedly connected to a threaded rod 72, and the surface of the threaded rod 72 is threadedly connected to a slider 73. The servo motor 71 is a prior art. The servo motor 71 can drive the threaded rod 72 to rotate forward and reverse, so that the slider 73 can drive the delivery head 75 to move back and forth, so that the plastic additives entering the delivery head 75 from the telescopic hose 5 can be delivered back and forth, avoiding direct delivery and accumulation on one side of the working box. The servo motor 71 is fixedly connected to the right outer wall of the guide frame 4, the threaded rod 72 is rotatably connected to the inner wall of the guide frame 4, the slider 73 is slidably connected to the inner wall of the top of the guide frame 4, and the bottom end of the outer wall of the slider 73 is rotatably connected to the delivery head 75 The telescopic hose 5 passes through and is fixedly connected to the inner wall of the slider 73. The end of the telescopic hose 5 away from the delivery bucket 1 is fixedly connected to the top of the outer wall of the delivery head 75. The elasticity of the telescopic hose 5 allows the threaded rod 72 to automatically extend and retract when driving the delivery head 75 to move back and forth. The outer wall of the top of the delivery head 75 is fixedly connected with a tooth block 74, which meshes with the rack 76. The meshing between the two allows the slider 73 to reciprocate on the surface of the threaded rod 72. The tooth block 74 on the outer wall of the delivery head 75 at its bottom end will mesh with the rack 76, so that the delivery head 75 will rotate itself when it reciprocates, making the delivery range of the plastic additives wider. Multiple sets of racks 76 are fixedly connected to the inner side wall of the delivery bucket 1.

[0037] Working principle: First, use bolts to cooperate with the mounting feet 6 to fix the whole on the top of the equipment to be dosed. Observe the position of the quantitative mechanism 2 through the observation window on the surface of the delivery barrel 1 to adjust it according to the amount of plastic additive to be delivered. Pull the plug 27 outward to disengage it from the through hole on the surface of the connecting rod 25. At this time, the connecting rod 25 can be moved up and down. Since the connecting rod 25 is fixedly connected to the moving rod 21, the moving rod 21 rises or falls in the delivery barrel 1 accordingly. After adjusting to the appropriate position, release the plug 27. Under the action of the limit spring 26, the plug 27 is inserted into the corresponding through hole to fix the connecting rod 25 and the moving rod 21, thereby adjusting the capacity of the delivery barrel 1 for storing additives.

[0038] When additives need to be added, the rotating rod 23 is rotated. Since the rotating rod 23 is elastically connected to the moving rod 21 through the spiral spring 28, the rotating rod 23 drives the positioning block B24 to rotate, opening the gap on the right half of the positioning block A22. At this time, the plastic additives accumulated on the surfaces of the positioning blocks A22 and B24 will fall into the telescopic hose 5 along the inclined surface of the positioning block A22.

[0039] The servo motor 71 is started, and its output shaft drives the threaded rod 72 to rotate forward and reverse. Since the threaded rod 72 is threadedly connected to the slider 73, and the slider 73 is slidably connected to the inner wall of the top of the guide frame 4, the slider 73 drives the delivery head 75 to reciprocate under the drive of the threaded rod 72. During the reciprocating movement of the slider 73, the tooth block 74 on the outer wall of the top of the delivery head 75 engages with the rack 76 fixed to the inner side wall of the delivery barrel 1. This engagement allows the delivery head 75 to rotate while the slider 73 reciprocates on the surface of the threaded rod 72.

[0040] Since the telescopic hose 5 is telescopic, when the delivery head 75 moves back and forth following the slider 73, the telescopic hose 5 will automatically expand and contract, ensuring that the plastic additive entering the delivery head 75 from the telescopic hose 5 can be delivered more widely and evenly under the reciprocating movement and rotation of the delivery head 75, avoiding direct delivery and causing the additive to accumulate on one side.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
