[0028] The drawings are only used for illustrative purposes and should not be construed as limitations of this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product.

[0029] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the utility model is further described below in conjunction with the drawings and embodiments.

[0030] As shown in the accompanying drawings, a material quantitative feeding machine for plastic products comprises a horizontally arranged fixed cylinder 1, and a movable cylinder 2 rotatably sleeved in the fixed cylinder 1, a feed trough 11 is provided on the upper side of the fixed cylinder 1, a discharge trough 12 is provided on the lower side of the fixed cylinder 1, an accommodating cavity 21 is formed on the outer side wall of the movable cylinder 2, and a loading hopper 3 is slidably connected in the accommodating cavity 21;

[0031] The loading hopper 3 can pass through the feeding trough 11 and extend to the outside of the fixed cylinder 1, or retract into the accommodating chamber 21, but the loading hopper 3 cannot pass through the discharging trough 12;

[0032] The end of the loading hopper 3 is integrally connected to a support seat 31, the end of the moving cylinder 2 is integrally connected to a cover body 4, the cover body 4 is provided with a long strip-shaped avoidance hole 41 for the support seat 31 to pass through, the end of the fixed cylinder 1 is integrally connected to a base 13, a first elastic member 51 is connected between the base 13 and the support seat 31, a limiting rod 61 parallel to the avoidance hole 41 is provided on the support seat 31, and a limiting hole 62 adapted to the limiting rod 61 is provided at the top end of the base 13, and the limiting rod 61 can be inserted into or withdrawn from the limiting hole 62;

[0033] It also includes a feeding assembly, which can drive the moving cylinder 2 to rotate when the loading hopper 3 is retracted into the accommodating chamber 21 and the limiting rod 61 is not inserted into the limiting hole 62.

[0034] Preferably, the feeding assembly includes a guide rail 71 and a transmission belt 72 which are parallel to each other, a feeding hopper 73 is slidably connected to the guide rail 71 , and the feeding hopper 73 is integrally connected to the transmission belt 72 .

[0035] Preferably, a moving seat 81 is slidably connected to the feeding hopper 73, a second elastic member 52 is connected between the moving seat 81 and the feeding hopper 73, a push plate 82 is integrally connected to the moving seat 81, a follower 42 abutting against the push plate 82 is integrally connected to the cover body 4, and a third elastic member 53 is connected between the follower 42 and the base 13.

[0036] In the unloaded state of the utility model, the first elastic member 51 allows the loading hopper 3 to extend through the feed trough 11 to the outside of the fixed cylinder 1. At this time, the loading hopper 3 is restricted by the feed trough 11, resulting in the inability of the moving cylinder 2 to rotate. When the weight of the material loaded in the loading hopper 3 is within the preset range of the supply amount, the loading hopper 3 overcomes the force of the first elastic member 51 and retracts into the accommodating chamber 21, and the limiting rod 61 is not inserted into the limiting hole 62. In this way, in the process of the transmission belt 72 driving the feeding hopper 73 to approach the fixed cylinder 1, the push plate 82 on the feeding hopper 73 can drive the moving cylinder 2 to rotate through the driven member 42, so that the loading hopper 3 is aligned with the discharge trough 12. Subsequently, the material in the loading hopper 3 falls into the feeding hopper 73 through the discharge trough 12, thereby achieving better control of the material supply amount.

[0037] After all the materials in the loading hopper 3 fall into the feeding hopper 73, the transmission belt 72 drives the feeding hopper 73 away from the fixed cylinder 1. Under the action of the third elastic member 53, the movable cylinder 2 rotates again until the loading hopper 3 is aligned with the feeding trough 11 again.

[0038] It is understandable that if the loading hopper 3 is restricted by the feed trough 11, resulting in the movable cylinder 2 being unable to rotate, in the process of the transmission belt 72 driving the feeding hopper 73 close to the fixed cylinder 1, the driven member 2 cannot move, thereby causing the movable seat 81 to compress the second elastic member 52, which helps to avoid a hard collision between the push plate 82 and the driven member 42.

[0039] Preferably, the end of the base 13 is rotatably connected to a rotating seat 91, and an adjustment rod 92 parallel to the avoidance hole 41 is threadedly connected to the rotating seat 91. One end of the first elastic member 51 is integrally connected to the support seat 31, and the other end of the first elastic member 51 is integrally connected to the adjustment rod 92.

[0040] It is understood that when the weight of the material loaded in the loading hopper 3 is equal to the minimum end value of the preset range of the supply amount, the open end of the loading hopper 3 is flush with the outer wall of the moving cylinder body 2, and the limit rod 61 is not inserted into the limit hole 62. At this time, the moving cylinder body 2 can rotate around the axis. By rotating the adjustment rod 92 to change the initial compression of the first elastic member 51, it is possible to change the force that needs to be overcome when the loading hopper 3 moves to the point where its open end is flush with the outer wall of the moving cylinder body 2, thereby changing the preset range of the supply amount. For example, when the initial compression of the first elastic member 51 increases, a greater force needs to be overcome to make the open end of the loading hopper 3 flush with the outer wall of the moving cylinder body 2, and then more material needs to be poured into the loading hopper 3. The operator can adjust the initial compression of the first elastic member 51 by rotating the adjustment rod 92 according to the approximate supply amount required for the product.

[0041] Preferably, the limiting rod 61 is threadedly connected to the supporting seat 31 .

[0042] It is understandable that when the weight of the material loaded in the loading hopper 3 exceeds the maximum end value of the preset range of the supply amount, the limit rod 61 will be inserted into the limit hole 62, causing the movable cylinder 2 to be unable to rotate around the axis. By rotating the limit rod 61 to change the initial distance between the limit rod 61 and the limit hole 62, the maximum end value of the preset range of the supply amount can be changed without changing the minimum end value of the preset range of the supply amount. For example, under the condition that the initial compression amount of the first elastic member 51 is constant, that is, the minimum end value of the preset range of the supply amount is unchanged, if the initial distance between the limit rod 61 and the limit hole 62 is reduced, the maximum end value of the preset range of the supply amount will become smaller, thereby reducing the preset range of the supply amount, and vice versa, the preset range of the supply amount is increased. The operator can adjust the initial distance between the limit rod 61 and the limit hole 62 by rotating the limit rod 62 according to the supply amount accuracy required by the product.

[0043] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
