Description

Technical Field

[0001] The utility model relates to the technical field of metering equipment, in particular to an output quantity control device and a counting machine. Background Art

[0002] In product packaging applications, before bulk products are bagged and packaged, a common counting method is to count by manual counting, taking a specified number of products and putting them into packaging bags.

[0003] The design of counting machines is extended from this. The application of counting machines is generally provided for a large number of products that need to be counted. The products are arranged in a certain structure and output in a set quantity.

[0004] Based on the understanding of counting machines, a counting machine with the Chinese publication number CN114408304B discloses a basic structure consisting of a feeding device, a feeding device, a first leveling mechanism, an output quantity control device, a material guide and a detection and counting device. It is found in the current literature that in the output quantity control device for material counting and output, its specific function is that the driving mechanism drives the transverse movement seat to move back and forth laterally along the mounting seat, and the transverse movement seat that moves back and forth laterally drives the longitudinal movement seat to move back and forth longitudinally relative to the transverse movement seat, and the coordinated cooperation of the transverse movement seat and the longitudinal movement seat drives the material control plate to swing back and forth, thereby realizing the opening / closing of the material control plate. However, it is found that when realizing the opening and closing of the material control plate, the linkage movement between the transverse movement seat and the longitudinal movement seat is involved, and the required precision is relatively high, resulting in a slight deviation causing the material control plate to be stuck in the feeding trough or the material control plate to be broken. Although it can be realized in terms of function, the technical complexity is relatively high. Utility Model Content

[0035] like Figure 1 As shown, an output quantity control device is provided, which is used to control the output quantity of materials on the material output path, and includes:

[0036] A push rod 1; a push rod mechanism 2, wherein the driving end of the push rod mechanism 2 is connected to one end of the push rod 1, and the push rod mechanism 2 is used to push the one end of the push rod 1 to move along the direction constrained by the push rod mechanism 2;

[0037] The material control assembly 3 includes a rotating shaft 31 and a material control plate 32. One end of the material control plate 32 is rotatably mounted on the rotating shaft 31, and one end of the material control plate 32 away from the rotating shaft 31 is connected to the other end of the push rod 1;

[0038] When the push rod mechanism 2 pushes one end of the push rod 1 to move, the other end of the push rod 1 moves synchronously and is restrained by the material control plate 32 to push the material control plate 32 to swing around the rotation axis 31 .

[0039] In this embodiment, an output quantity control device is provided, in which the push rod 1 is pushed by the push rod mechanism 2 to move, so that the material control plate 32 is restricted to swing by the rotating shaft 31, and then the material conveying path can be partially or completely blocked by the material control plate 32, thereby achieving the purpose of controlling material output and controlling material flow. The output quantity control device in the scheme is designed to be implemented only by the push rod 1, the push rod mechanism 2 and the material control component 3, and the overall design structure is simple and practical.

[0040] It should be noted that the partial blocking and complete blocking methods indicated in the above description are mainly implemented by the push rod mechanism 2. The push rod mechanism 2 can control the pushing distance of the push rod 1 and then control the position of the material control plate 32 after the swing. When applied to material transportation, the size of the material output port can be controlled; for the state of partial blocking, the material control plate 32 is swung to partially close the material conveying path, and for the state of complete blocking, the material control is swung to completely close the material conveying path.

[0041] In this embodiment, the specific structure of the push rod mechanism 2 includes:

[0042] The U-shaped mounting base 21 provides a mounting space for the screw rod 22;

[0043] A screw rod 22 rotatably mounted on the mounting base 21 ;

[0044] A moving block 23 is mounted on the screw rod 22. The moving block 23 is capable of reciprocating on the screw rod 22 by the rotation of the screw rod 22. One end of the push rod 1 is fixed to the upper end of the moving block 23.

[0045] The drive motor 24 is mounted on one side of the mounting base 21 . The drive end of the drive motor 24 is in transmission connection with the screw rod 22 to drive the screw rod 22 to rotate.

[0046] The driving motor 24 drives the screw rod 22 to rotate, so that the screw rod 22 and the moving block 23 drive the moving block 23 to move left and right on the screw rod 22 in a transmission manner, and one end of the push rod 1 is installed on the moving block 23, so that one end of the push rod 1 can be moved. In addition, the other end of the push rod 1 is installed on the material control plate 32. When one end of the push rod 1 moves, the other end of the push rod 1 is restricted by the material control plate 32, so that the storage state of the push rod 1 moves from a state close to parallel to the screw rod 22 to a state perpendicular to the screw rod 22. At this time, the other end of the push rod 1 is away from the mounting seat 21, so that the swing of the material control plate 32 can be controlled.

[0047] In addition, the push rod mechanism 2 also includes:

[0048] A guide rod 25 , which is fixedly mounted on the base and arranged close to the screw rod 22 ;

[0049] The guide rod 25 passes through the moving block 23 , and the moving block 23 can slide relative to the guide rod 25 .

[0050] One of the functions of the guide rod 25 is to prevent the moving block 23 from being constrained in its moving state when moving on the screw rod 22, and to prevent the moving block 23 from swinging. The second function of the guide rod 25 is to specify the moving path of the moving block 23, to prevent it from having movement deviation, and to make the swing position of the material control plate 32 accurate.

[0051] Furthermore, in order to make the installation position between the drive motor 24 and the mounting base 21 compact enough, the push rod mechanism 2 also includes: a transmission assembly 26, the transmission assembly 26 includes a driving wheel (not shown), a driven wheel (not shown) and a belt 261 arranged around the driving wheel (not shown) and the driven wheel (not shown), the driving wheel (not shown) is installed on the driving end of the drive motor 24, the driven wheel (not shown) is sleeved on the screw rod 22, the driving end of the drive motor 24 drives the driving wheel (not shown) to rotate and then drives the driven wheel (not shown) to rotate through the belt 261 to drive the screw rod 22 to rotate.

[0052] This design allows the drive motor 24 and the mounting base 21 to be arranged in an upper and lower state, thereby achieving compact installation. Since the output quantity control device is one of the linear structures in material processing, such as one of the assembly line processing devices, it is necessary to keep the occupation of horizontal space reduced, and thus the structure of the counting machine using the output quantity control device of this embodiment can be as compact as possible.

[0053] Preferably, the material control plate 32 is an elongated material control plate 32 , which can meet the application requirements of blocking the material conveying path and can meet the application requirements of controlling the size of various material output ports.

[0054] Regarding the arrangement structure of the push rod 1, based on the application principle of the output control device in this embodiment, the push rod 1 needs to rotate relative to the push rod mechanism 2 and the material control plate 32, so mounting holes 11 are configured at both ends of the push rod 1;

[0055] The two ends of the push rod 1 are respectively mounted on the push rod mechanism 2 and the material control plate 32 via a pin shaft 12 passing through the corresponding mounting holes 11 ; the two ends of the push rod 1 can rotate around the pin shaft 12 .
