Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a multi-head scale anti-blocking device. Background Art

[0002] A multi-head scale is a computer combination scale, which is actually a "weighing bucket". The multi-head scale is composed of multiple independent weighing units with feeding and discharging structures. The computer uses the principle of permutation and combination to automatically optimize and combine the load of the weighing units to obtain the best weight combination that is closest to the target weight value. The existing multi-head scales are divided into 8 buckets, 10 buckets, 12 buckets, 14 buckets, 16 buckets, 20 buckets, 24 buckets, etc. However, when using multiple groups of weighing buckets to discharge materials at the same time, it is easy to cause material jamming and discharge port blockage, affecting work efficiency.

[0003] China Patent Network discloses a new type of anti-blocking multi-head scale (publication number: CN 208765830 U), including a base, a feed hopper, a weighing hopper, and a discharge hopper. The bottom end of the feed hopper is connected to the weighing hopper, and the bottom end of the weighing hopper is arranged at the top of the discharge hopper. The discharge hopper is welded to the top of the base, and the base is a U-shaped structure. At least two groups of protrusions are arranged on the outside of the base, and at least two groups of the protrusions are welded with vertical rods at the upper ends, and a horizontal plate is welded at the top of one side of the vertical rod, and a feeding tray is welded on the other side of the horizontal plate, and a vibrating feeder is arranged at the bottom of the feeding tray. Through the use of a motor and a circular plate, the material inside the symmetrical weighing hopper can be unloaded in turn to avoid jamming; driven by an electric push rod, the distance between the tray and the ground can be changed, thereby changing the distance between the storage barrel and the ground, so that storage barrels of different heights can store materials, and the versatility is strong.

[0004] The above technology uses the motor and the circular plate to make the materials in the weighing hopper be discharged in sequence, avoiding the occurrence of material jams and thus preventing blockages. However, there are the following defects: the motor is installed in the discharge hopper through a box body and a diagonal rod support. When the food entering the discharge hopper is in the shape of strips, it is easy to cause the strips of food to hang in the diagonal rods, thereby affecting the weighing and even causing blockages. Therefore, there is room for improvement. Utility Model Content

[0005] The utility model provides a multi-head scale material blocking prevention device to solve the problems raised in the background technology.

[0006] In order to solve the above problems, the present invention provides a multi-head scale anti-blocking device, comprising a multi-head scale body, the multi-head scale body is fixedly connected to the outside with a support frame, a discharge plate is fixedly arranged below the multi-head scale body, and a plurality of discharge troughs for docking with the discharge end of the weighing bucket in the multi-head scale body are opened in the discharge plate, an anti-blocking mechanism is arranged below the discharge plate, and the anti-blocking mechanism is composed of a discharge hopper rotatably arranged below the discharge plate and a motor driving the discharge hopper to rotate, the top of the discharge hopper is rotatably connected to the lower end of the discharge plate, and a cover plate that contacts the lower surface of the discharge plate is fixedly arranged on the upper inner part of the discharge hopper, a lower trough matching the discharge trough is opened in the cover plate, a circle of gear ring is fixedly arranged around the outer surface of the discharge hopper, the motor is fixedly arranged on the support frame, and a gear meshing with the gear ring is fixedly arranged in the power output shaft.

[0007] Preferably: an annular sliding groove is provided on the outer edge of the discharge plate, and an annular sliding block slidably connected to the sliding groove is provided on the inner side of the top of the discharge hopper above the cover plate.

[0008] Preferably: a discharge port is provided at the lower part of the discharge hopper, and the discharge port is rotatably connected to the fixed plate, both ends of the fixed plate are fixedly installed in the support frame, an annular groove is provided in the outer surface of the discharge port, a mounting hole connected to the discharge port is provided in the middle part of the fixed plate, and a convex ring slidably connected to the annular groove is fixed in the mounting hole.

[0009] The beneficial effects of adopting the above technical solution are:

[0010] The rotation of the motor drives the gear ring at the end to drive the discharge hopper to rotate under the discharge plate, and then the discharge groove in the cover plate cooperates with the discharge groove in the discharge plate to allow multiple weighing hoppers in the multi-head scale body to discharge materials in sequence to prevent blockage. Since the external gear ring cooperates with the gear to rotate under the drive of the motor, the internal inclined rod can be avoided to cause hanging materials to affect the weighing. At the same time, the rotation of the discharge hopper can avoid the problem of blockage caused by internal accumulation of materials. BRIEF DESCRIPTION OF THE DRAWINGS
