DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] As Figures 1-7 indicated, the utility model provides a kind of weighing mechanism for plastic particles, mainly for the effect of completing plastic particle automatic feeding and weighing, when the weight of plastic particle of weighing reaches specified setting data, can automatically stop feeding, entire feeding process does not need manual intervention, it is easy to operate.

[0028] The entire weighing mechanism includes weighing base 1 and feeding head 2 two parts, when connecting, one side of weighing base 1 is connected with feeding head 2 by support frame 3, so that feeding head 2 is arranged above weighing base 1. Feeding is mainly completed by one end of feeding head 2, and weighing is completed by one end of weighing base 1.

[0029] Sensor 4 is installed in weighing base 1, sensor 4 is connected with weighing plate 6, weighing plate 6 is detachably connected with charging container 8, charging container 8 is clamped and fixed by the clamp ring 9 of the upward protrusion of weighing plate 6, and the plastic particles falling from feeding head 2 fall directly into charging container 8, at this time, sensor 4 can detect the weight of plastic particles in real time.

[0030] When sensor 4 and weighing plate 6 are installed on weighing base 1, mounting groove 13 for installing sensor 4 and weighing plate 6 is opened in weighing base 1, wherein weighing plate 6 is ejected towards the upper side of weighing base 1 after installation.

[0031] In order to further reinforce the position of the loading container 8 and ensure that it will not move during the discharging process, a clamping ring 9 is arranged in the middle of the weighing plate 6 and a clamping groove 15 matching the clamping ring 9 is arranged in the bottom of the loading container 8. The arrangement of the clamping ring 9 avoids the movement of the loading container 8 affecting the weighing during the discharging process and facilitates the replacement of different sizes of the loading container 8.

[0032] At one end of the discharging head 2, a discharging channel 10 is arranged in the discharging head 2 and the bottom opening of the discharging channel 10 is aligned with the loading container 8. When the plastic particles are discharged, they directly fall into the loading container 8 from the discharging channel 10 for real-time weighing. In order to facilitate feeding, a feeding port 16 is arranged in the top of the discharging head 2 and is in communication with the discharging channel 10. The cross section of the feeding port 16 is in an inverted trapezoidal structure. At this time, all the plastic particles will slide along the inner wall of the feeding port 16 and fall into the discharging channel 10.

[0033] In order to control the speed of discharging, a rotating plate 12 that can rotate is arranged in the discharging channel 10 to control the speed of discharging. When installed, a motor 11 is arranged on the outside of the discharging head 2 and the output end of the motor 11 is connected with the rotating plate 12 arranged horizontally in the discharging channel 10. At this time, when the rotating plate 12 rotates, the two ends of the rotating plate 12 close to the output end of the motor 11 are tightly attached to the inner wall of the discharging channel 10 and the two ends of the rotating plate 12 away from the output end of the motor 11 are in contact with the inner wall of the discharging channel 10 when they are rotated to a horizontal state. When the rotating plate 12 is connected with the motor 11, a plug hole 18 is arranged in the middle of the side surface of the rotating plate 12 and is in plug-in connection with the output end of the motor 11. The output end of the motor 11 is provided with a clamping part 19 embedded in the inner wall of the plug hole 18 and fixed.

[0034] When the discharging starts, the rotating plate 12 can be in a completely vertical state and the speed of discharging is the largest at this time. When the weight approaches the set value, the rotating plate 12 can be gradually rotated horizontally under the control of the motor 11 to reduce the speed of discharging and stop the discharging through the horizontal arrangement.

[0035] The inner wall of the discharging channel 10 is provided with two concave arc surfaces 17 and the curvature of the arc surfaces 17 is the same as the curvature of the two ends of the rotating plate 12 away from the output end of the motor 11. This arrangement can avoid the gap between the rotating plate 12 and the discharging channel 10.

[0036] In order to realize the linkage between the weighing and the discharging, a controller 5 is arranged in the weighing base 1. At this time, the controller 5 is connected with the sensor 4 and the motor 11. In addition, an adjusting panel 7 connected with the controller 5 is arranged on one side of the weighing base 1 to complete the linkage operation of the pre-setting, discharging and weighing detection before the discharging. The adjusting panel 7 is arranged on one side of the weighing base 1 and an inclined surface 14 is arranged on one side of the weighing base 1. The adjusting panel 7 is installed on the inclined surface 14 to facilitate the operation adjustment.

[0037] Before use, the user can set the weight of the plastic particles through the adjusting panel 7, and the motor 11 drives the rotating plate 12 to gradually start the feeding, when the sensor 4 detects that the weight of the plastic particles gradually approaches the preset value, at this time the motor 11 can control the rotating plate 12 to rotate horizontally, slow down the feeding speed, until the weight of the plastic particles is enough, the rotating plate 12 rotates to the horizontal state to stop feeding. It needs to be noted that, in order to reduce the error of feeding, the rotating plate 12 should be set at one end close to the discharge port of the feeding channel 10, and the discharge port of the feeding channel 10 is also close to the charging container 8, at this time the weighing amount can be met, and the error will not be too large.

[0038] Compared with the prior art, the weighing mechanism provided by the technical scheme adds the controller 5 connected with the sensor 4, the adjusting panel 7 and the motor 11, realizes the synchronous detection and control of the plastic particle weighing and feeding, ensures the accuracy of weighing, and improves the efficiency of weighing. In addition, the rotating plate 12 controlled by the motor 11 can control the speed of the plastic particle feeding according to the angle of rotation, and has good flexibility. The charging container 8 is fixed by the protruding snap ring 9, which avoids the movement of the charging container 8 affecting the weighing during feeding, and facilitates the user to replace the charging container 8 of different sizes for use.

[0039] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application, and any reference signs in the claims should not be regarded as limiting the claims.
