Description

Technical Field

[0001] The utility model relates to the technical field of counting and packaging industry, and more specifically to a chamfered anti-stuck material structure of a back plate at the rear of a feed bin. Background Art

[0002] The counting packaging industry uses counting machines to accurately count the products in the package to ensure that the product quantity matches the label, thereby protecting the brand reputation after purchase, reducing product waste, and improving marketing effectiveness. The implementation of counting packaging relies on advanced counting technologies that can ensure the accuracy of counting, thereby protecting the interests of consumers and enhancing brand trust.

[0003] When using a grain counting machine with a pull-out door structure to count materials with hard outer packaging bag edges, there is a certain friction between the material and the pull-out door, and the material will move inward and outward with the pull-out door, causing the material to be stuck between the two rear backboards of the receiving hopper, reducing the counting accuracy and easily pinching and damaging the material; although making wavy grooves on the backboard and the pull-out door can solve the problem, it will increase the processing cost. In view of this, we propose a chamfered anti-stuck material structure at the rear backboard of the discharge hopper. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide a chamfered anti-stuck material structure on the rear backboard of the unloading hopper to solve the technical problem that the pulling and inserting door in the receiving hopper of the current grain counting machine easily causes the material to be stuck between the two rear backboards of the receiving hopper, thereby reducing the counting accuracy and easily clamping and damaging the material.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a chamfered anti-stuck structure for the back panel of a lower material bin, comprising a side panel of a receiving material bin, wherein a rear upper back panel, a rear middle back panel-upper, a rear middle back panel-lower and a rear lower back panel are sequentially arranged on the front side of the side panel of the receiving material bin from top to bottom, an opening is reserved between the rear middle back panel-upper and the rear middle back panel-lower, the rear middle back panel-lower and the rear lower back panel, chamfers are added to the lower sides of the rear middle back panel-upper and the rear middle back panel-lower, a module bracket is arranged on one side of the rear middle back panel-lower, and drawer doors corresponding to the openings are arranged above and below the module bracket;

[0006] Extension plates are hingedly arranged on the top and bottom of the drawer door toward one side of the material receiving bin side plate, and a rectangular hole is opened on the top of the drawer door facing away from the material receiving bin side plate, and a driving structure is arranged inside the rectangular hole.

[0007] The present invention solves the problem of material jamming by adding a chamfer to the lower sides of the rear middle back panel-upper and the rear middle back panel-lower of the material receiving bin side panels, so that when the drawer door is fully moved inward, the packaging edge of the material has no force point, so that it can be stuck between the two rear back panels, thereby solving the problem of material jamming; the present invention also solves the problem of material jamming by hingedly arranging extension panels at the upper and lower ends of the drawer door, and arranging a driving structure on the drawer door, so that when the drawer door moves outward, the driving structure can synchronously control the upper and lower sets of extension panels of the drawer door to slowly extend or retract, so that the surfaces of the two sets of extension panels can respectively come into close contact with the opening edges between the rear middle back panel-upper, the rear middle back panel-lower and the rear lower back panel, thereby effectively preventing the material from being subjected to friction when the drawer door moves outward, causing the material packaging to be stuck in the gap between the drawer door and the rear middle back panel-upper, the rear middle back panel-lower and the rear lower back panel, thereby further avoiding the material jam phenomenon and better ensuring the integrity of the material.

[0008] Preferably, the driving structure includes a second cylinder and a cross bar, the cross bar is slidably arranged inside the rectangular hole, the second cylinder is arranged in the center of one side of the rectangular hole, and the piston end of the second cylinder is connected to the cross bar, and the upper and lower ends of the cross bar are hingedly arranged with connecting rods, the two groups of connecting rods above the cross bar are hingedly connected to the top extension plate of the pull-out door, and the two groups of connecting rods below the cross bar are hingedly connected to the bottom extension plate of the pull-out door.

[0009] Preferably, the rectangular hole is provided with sliding grooves at the front and rear, and the two ends of the cross bar are arranged inside the sliding grooves.

[0010] Preferably, the front side panel of the receiving bin is provided with a front window-upper and a front window-lower in sequence from top to bottom on the side facing away from the rear upper back panel. The front window-upper and the rear upper back panel are tilted symmetrically, and the front window-lower is vertically symmetrical with the rear middle back panel-upper, the rear middle back panel-lower and the rear lower back panel.

[0011] Preferably, a first cylinder is arranged on the top and bottom of the module bracket on the side facing away from the side plate of the material receiving bin, and a connecting plate is arranged on the piston end of the first cylinder, and the connecting plate is connected to the insertion and extraction door.

[0012] Preferably, the connection plate is symmetrically arranged with directional rods diagonally facing one side of the first cylinder, and the directional rods pass through the module bracket.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model adds a chamfer to the lower side of the rear middle back plate - upper and the rear middle back plate - lower of the side plate of the material receiving bin, so that when the insertion and withdrawal door moves completely inward, the packaging edge of the material has no force point so that it can be stuck between the two rear back plates, thereby solving the problem of material jamming. It also solves the technical problem that the insertion and withdrawal door in the material receiving bin of the current grain counting machine easily causes the material to be stuck between the two rear back plates of the material receiving bin, thereby reducing the grain counting accuracy and easily clamping and damaging the material. Therefore, the utility model has the advantages of not being easy to jam the material, having high grain counting accuracy and not being easy to clamp and damage the material.

[0015] 2. The present invention also provides extension plates hinged at the upper and lower parts of the drawer door, and provides a driving structure on the drawer door. Therefore, when the drawer door moves outward, the driving structure can synchronously control the upper and lower groups of extension plates of the drawer door to slowly extend or retract, so that the surfaces of the two groups of extension plates can be in close contact with the opening edges between the rear middle back plate-upper, the rear middle back plate-lower and the rear lower back plate respectively, thereby effectively preventing the material from being subjected to friction when the drawer door moves outward, causing the material packaging to be stuck in the gap between the drawer door and the rear middle back plate-upper, the rear middle back plate-lower and the rear lower back plate, thereby further avoiding the material from being stuck and better ensuring the integrity of the material.
