DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the embodiments and drawings. The schematic implementation mode and description of the utility model are only used to explain the utility model and are not intended to limit the utility model. It should be noted that the utility model is already in the actual development and use stage.

[0031] In the existing quantitative filling device, a valve is usually set at the discharge port below the silo, and then when the amount of discharged material (volume or mass) reaches the preset quantitative filling value, the valve is controlled to close, and the discharged material is used for one-time quantitative packaging. However, such a quantitative filling device needs to frequently open and close the valve at the discharge port of the silo, resulting in intermittent discharge of the silo. This intermittent discharge and filling mode seriously reduces the efficiency of quantitative filling. The utility model proposes a hopper device for pellet filling, which can realize quantitative filling of plastic pellets, and during the filling process, the silo discharges continuously, and the filling efficiency is high.

[0032] Embodiment 1:

[0033] like Figure 1 , Figure 3 , Figure 4 As shown, the present embodiment provides a hopper device for pellet packaging, comprising a silo 2 fixedly mounted on a bracket 1, and further comprising:

[0034] Rotate the turntable 3 mounted on the bracket 1;

[0035] A plurality of sub-filling buckets 4 are arranged in a circular array along the rotation axis of the turntable 3, and the discharge port 21 of the silo 2 is connected to the top of any sub-filling bucket 4; for any of the sub-filling buckets 4, the sub-filling bucket 4 is installed on the turntable 3 through a weighing sensor 5; and,

[0036] A control component, each of the weighing sensors 5 is electrically connected to the control component, and the control component can control the turntable 3 to rotate to a preset angle.

[0037] Based on this, the embodiment of the utility model provides a hopper device for pellet packaging, through multiple packaging hoppers 4 corresponding to a silo 2, when the weight of the pellets injected into one of the packaging hoppers 4 from the silo 2 reaches the preset quantitative packaging amount, the control component controls the rotation of the turntable 3, so that the discharge port 21 of the silo 2 is connected to the top of the next packaging hopper 4, and then the pellets are injected into the next silo 2. Therefore, when the hopper device for pellet packaging provided by this embodiment is used for quantitative pellet packaging, the silo 2 is in a state of continuous feeding, which directly saves the "idle" time of the valve of the discharge port 21 of the silo 2 from closing to reopening, greatly improving the efficiency of quantitative packaging.

[0038] Specifically, this embodiment adopts the following method to realize the rotation of the turntable 3:

[0039] A motor 6 is fixedly mounted on the bracket 1, and the motor 6 is electrically connected to the control assembly; a first gear 61 is arranged on the output shaft of the motor 6; and a second gear 31 is sleeved on the outer circumference of the turntable 3 and meshes with the first gear 61. Thus, according to the transmission ratio between the first gear 61 and the second gear 31, the rotation angle of the motor 6 is controlled by the control assembly, and the turntable 3 can be controlled to rotate by a preset angle. More specifically, the motor 6 is a stepper motor 6 or a servo motor 6. By using a stepper motor 6 or a servo motor 6 to drive the rotation of the turntable 3, the rotation angle of the turntable 3 can be accurately controlled. It should be understood that in order to facilitate the timely departure of the sub-packaging bucket 4 from the bottom of the discharge port 21, the rotation of the turntable 3 should be intermittent. When rotating, the sub-packaging bucket 4 is rotated to a position about to leave the bottom of the discharge port 21 and stops rotating. When the particles in the sub-packaging bucket 4 reach a preset mass, the motor 6 drives the turntable 3 to rotate again, so that the sub-packaging bucket 4 leaves the bottom of the discharge port 21 in time.

[0040] Preferably, in order to improve the accuracy of quantitative packaging and reduce packaging errors, a material guide 13 fixedly mounted on the turntable 3 is further provided above any two adjacent packaging buckets 4, the middle portion of the material guide 13 protrudes upward to form a sharp ridge, and the two ends of the material guide 13 are respectively located above the two adjacent packaging buckets 4. Thus, the position where the turntable 3 stops rotating can be set at the position of the discharge port 21 close to the sharp ridge, and then, when the particles in the packaging bucket 4 on one side of the sharp ridge reach a preset mass, the rotation of the turntable 3 can make the particles discharged from the discharge port 21 completely injected into the packaging bucket 4 on the other side of the sharp ridge, which can reduce the amount of particles still injected into the packaging bucket 4 from the time when the particles in the packaging bucket 4 reach the preset mass to the time when the packaging bucket 4 completely leaves the discharge port 21.

[0041] Furthermore, in order to facilitate the integration of the hopper device for pellet subpackaging and the subsequent subpackaging device (a device on the pellet production line for loading pellets into a preset container and packing and sealing the container) into the same production line, in a hopper device for pellet subpackaging provided in this embodiment, for any of the subpackaging hoppers 4, a discharge port 41 is provided at the lower part of the subpackaging hopper 4, and a discharge valve is also provided on the subpackaging hopper 4, and the discharge valve is used to control the opening and closing of the discharge port 41. A collection hopper 12 is also provided on the bracket 1, and the collection hopper 12 is used to feed the packaging device; a connecting pipe 32 corresponding to each of the subpackaging hoppers 4 is also provided on the turntable 3, and the feed end 321 of the connecting pipe 32 is located below the corresponding discharge port 41, and the discharge end 322 of each of the connecting pipes 32 is connected to the collection hopper 12.

[0042] Based on this, for any filling hopper 4, when the filling hopper 4 receives the preset mass of pellets, the turntable 3 rotates so that the next filling hopper 4 is located below the discharge port 21 of the silo 2, and the filling hopper 4 that receives the preset mass of pellets releases the pellets (the preset quantitative filling amount of pellets) in the filling hopper 4 by opening the discharge valve, and the pellets enter the collecting hopper 12 through the connecting pipe 32, and then are input into the preset container and packaged and sealed. When the current filling hopper 4 completes the pellet reception and pellet release process, the next filling hopper 4 is receiving pellets; before the next filling hopper 4 releases the pellets, the pellets in the current filling hopper 4 have been packaged and sealed; and the packaging and packaging of the pellets in the current filling hopper 4 and the injection of the pellets in the next filling hopper 4 are carried out simultaneously, without interfering with each other. Therefore, the hopper device for pellet packaging provided in this embodiment can be conveniently integrated with the packaging device into the same production line.

[0043] Preferably, the bracket 1 includes an annular support portion 14, and a plurality of balls 141 are embedded on the upper surface of the support portion 14; the lower end surface of the turntable 3 abuts against each of the balls 141; the lower end surface of the turntable 3 also extends downward with a limiting shaft tube 33, and the limiting shaft tube 33 is inserted into the support portion 14. Based on this, by embedding a plurality of balls 141 on the upper surface of the support portion 14 and abutting the lower end surface of the turntable 3 against the balls 141, the friction between the lower end surface of the turntable 3 and the upper surface of the support portion 14 during relative rotation can be greatly reduced, so that the rotation of the turntable 3 is smoother; by matching the limiting shaft tube 33 with the corresponding holes on the support portion 14, the radial movement of the turntable 3 is limited. In order to make the rotation smoother, a bearing can also be provided between the limiting shaft tube 33 and the holes on the support portion 14.

[0044] More preferably, a plurality of annular ridges 22 are provided on the outer peripheral surface of the silo 2. These annular ridges 22 can significantly improve the structural strength of the silo 2 while slightly increasing the weight of the silo 2.

[0045] Embodiment 2:

[0046] like Figures 1 to 6 As shown, this embodiment is based on embodiment 1, and the difference is that:

[0047] The discharge valve includes a blocking valve plate 421, and the end surface of the blocking valve plate 421 abuts against the discharge port 41;

[0048] A rotating shaft 43 is hingedly provided on the dispensing bucket 4, and the blocking valve plate 421 is connected to the rotating shaft 43 via a connecting rod 422;

[0049] Rotating the rotating shaft 43 can cause the blocking valve plate 421 to open or close the discharge port 41 .

[0050] Specifically, a push rod 44 is further provided on the rotating shaft 43, and a stop rod 11 is provided on the bracket 1;

[0051] For any of the dispensing buckets 4, when the rotary disk 3 rotates to make the dispensing bucket 4 leave the bottom of the discharge port 21, the push rod 44 abuts against the stop rod 11, so that the blocking valve plate 421 rotates around the rotating shaft 43 and opens the corresponding discharge port 41;

[0052] When the turntable 3 rotates so that the next dispensing bucket 4 leaves below the discharge port 21, the push rod 44 separates from the stop rod 11;

[0053] The discharge valve further includes a return spring, one end of which is connected to the filling bucket 4 , and the other end of which is connected to the blocking valve plate 421 .

[0054] Therefore, the embodiment of the utility model provides a hopper device for pellet packaging, in which the discharge valve of each filling hopper 4 can automatically open and close with the rotation of the turntable 3, without the need to control the opening and closing of the discharge valve separately. Figure 5 , Figure 6 ,like Figure 5 , Figure 6 As shown, when the turntable 3 rotates to make the current filling bucket 4 leave from under the discharge port 21 of the silo 2, the next filling bucket 4 enters under the discharge port 21. Thereafter, for the current filling bucket 4, its push rod 44 abuts against the stop rod 11 fixed on the bracket 1. As the turntable 3 continues to rotate, the rotating shaft 43 rotates to make the blocking valve plate 421 deflect and thus open the discharge port 41, and the return spring accumulates elastic potential energy; until the push rod 44 and the stop rod 11 are separated (the end of the push rod 44 slides away from the stop rod 11), the return spring releases the elastic potential energy to make the blocking valve plate 421 close the discharge port 41 of the filling bucket 4 again.

[0055] It should be understood that by adjusting the length of the push rod 44, the opening time of the discharge port 41 of the sub-packaging bucket 4 can be changed, and the opening time should be sufficient to discharge all the particles in the sub-packaging bucket 4. After that, the particles in the sub-packaging bucket 4 enter the subsequent packaging device through the collection bucket 12 for packaging and packaging, and the packaging and packaging are completed before the push rod 44 of the next sub-packaging bucket 4 abuts against the stop rod 11.

[0056] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
