Technical Field

[0001] The utility model relates to the field of checkweighing equipment, in particular to a checkweighing scale. Background Art

[0002] Existing checkweighers, such as the intelligent high-speed checkweigher proposed in publication number CN210546441U, include a feeding conveyor belt, a weighing conveyor belt, and a reject conveyor belt arranged in sequence, wherein the weighing conveyor belt is entirely arranged on a weighing sensor, and the material passes through the feeding conveyor belt, the weighing conveyor belt, and the reject conveyor belt in sequence. The material is weighed while moving as it passes through the weighing conveyor belt. However, the weighing conveyor belt is entirely arranged on the weighing sensor, and the vibration generated by the operation of the weighing conveyor belt will affect the weighing accuracy. At the same time, the mobile weighing method will also affect the weighing accuracy. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to address the deficiencies of the above-mentioned prior art.

[0004] A checkweigher is provided, in which the material is stationary on the weighing device for static weighing, and the conveying device does not contact the weighing sensor, so as to avoid the vibration of the conveying device affecting the weighing accuracy.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a checkweigher, comprising a base frame and an electrical control box arranged on one side of the base frame, characterized in that: a panel is provided axially above the base frame, an opening is provided axially through the panel, a weighing device is provided in the opening, a pushing device for pushing the material displacement is provided on the panel, and the pushing device does not contact the weighing device.

[0006] A further configuration of the utility model is: the weighing device includes a weighing sensor body, a weighing panel is linked to the axially upper side of the weighing sensor body, the weighing sensor body is connected to the axially lower side of the panel through a connecting seat, the weighing panel is arranged in the opening, the weighing panel is adapted to the opening, and the upper end face of the weighing panel is flush with the axially upper end face of the panel.

[0007] The utility model is further configured as follows: the pushing device includes a driving wheel and a driven wheel relatively arranged at both ends of the panel, a transmission belt is connected between the driving wheel and the driven wheel, the transmission belt is arranged in an orderly manner with push plates, and a material placement groove is formed between adjacent push plates, and a first transmission belt groove adapted to the transmission belt is opened through the upper end surface of the panel from the driving wheel to the driven wheel, the first transmission belt groove passes through the opening, the weighing panel is provided with a second transmission belt groove, the second transmission belt groove is aligned with the first transmission belt groove, the part of the transmission belt moved to the upper end of the panel passes through the first transmission belt groove and the second transmission belt groove, and the axial depth of the second transmission belt groove is greater than the axial depth of the first transmission belt groove.

[0008] The utility model with the above-mentioned characteristics: the push plate on the transmission belt drives the material to move, the depth of the second transmission belt groove is greater than the depth of the first transmission belt groove, the transmission belt only contacts the bottom of the first transmission belt groove, and is suspended in the second transmission belt groove to avoid the transmission belt from contacting the weighing panel, thereby improving the weighing accuracy. When the material placement slot with the material reaches the weighing panel, the transmission belt stops and retreats to the push plate on the transmission belt that abuts the material to separate from the material. After the material is weighed, the transmission belt continues to move forward, and the push plate abuts against and pushes the material to move, so that the material does not contact with additional objects during weighing, thereby ensuring the accuracy of weighing.

[0009] A further configuration of the present invention is that the driving wheel is linked with a servo motor for driving the driving wheel to rotate.

[0010] The utility model with the above characteristics: the servo motor can realize the advance and retreat of the transmission belt.

[0011] A further configuration of the present invention is that the electric control box is linked to the weighing sensor body and the servo motor.

[0012] The utility model has the above characteristics: the electric control box controls the weighing sensor body and the operation of the servo motor and the signal exchange.

[0013] The beneficial effects of the utility model are as follows: the material is stationary on the weighing device for static weighing, and the conveying device does not contact the weighing sensor, thereby preventing the conveying device from vibrating and affecting the weighing accuracy.

[0014] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 —— Figure 4 The checkweigher shown in the figure includes a base frame 1 and an electric control box 2 arranged on one side of the base frame 1. A panel 3 is provided axially above the base frame 1, and an opening 4 is axially passed through the panel 3. A weighing device is provided in the opening 4. A pushing device for pushing the material displacement is provided on the panel 3, and the pushing device does not contact the weighing device. The weighing device includes a weighing sensor body 5, and a weighing panel 6 is provided on the axial upper side of the weighing sensor body 5. The weighing sensor body 5 is connected to the axial lower side of the panel 3 through a connecting seat 7. The weighing panel 6 is arranged in the opening 4, and the weighing panel 6 is adapted to the opening 4. The upper end face of the weighing panel 6 is flush with the axial upper end face of the panel 3. The pushing device includes a driving wheel 8 and a driven wheel 9 relatively arranged at both ends of the panel 3. A transmission belt 10 is connected between the driving wheel 8 and the driven wheel 9. The transmission belt 10 is arranged in an orderly manner with push plates 11, and a material placement groove 12 is formed between adjacent push plates 11, which passes through the panel 3 in the direction from the driving wheel 8 to the driven wheel 9. The first transmission belt groove 13 is provided on one side of the square end surface, which is adapted to the transmission belt 10. The first transmission belt groove 13 passes through the opening 4. The weighing panel 6 is provided with a second transmission belt groove 14. The second transmission belt groove 14 is aligned with the first transmission belt groove 13. The part of the transmission belt 10 moving to the upper end of the panel 3 passes through the first transmission belt groove 13 and the second transmission belt groove 14. The axial depth of the second transmission belt groove 14 is greater than the axial depth of the first transmission belt groove 13, so that the transmission belt 10 is suspended in the second transmission belt groove 14. A gap 15 is provided between the transmission belt 10 and the bottom of the second transmission belt groove 14. When the material placement groove 12 with the material reaches the weighing panel 6, the transmission belt 10 stops and retracts to the push plate 11 on the transmission belt 10 that abuts the material to separate from the material. After the material is weighed, the transmission belt 10 continues to move forward, and the push plate 11 abuts against and pushes the material to move. The driving wheel 8 is linked with a servo motor 16 that drives it to rotate. The electronic control box 2 is linked with the weighing sensor body 5 and the servo motor 16.
