Description

Technical Field

[0001] This utility model relates to the field of high-accuracy counting structure technology for packaging machines, specifically a high-accuracy counting structure for packaging machines. Background Technology

[0002] Packaging machines use high-accuracy particle counting structures to accurately count solid particles, ensuring that the number of particles in each package of product meets the set value.

[0003] For example, a quantitative counting mechanism based on an automatic packaging machine, authorized by announcement number "CN211224177U", can intermittently block the material fed into the trough through the pusher assembly and slide plate, ensuring that the amount of granules falling into the cavity each time is equal, thereby achieving accurate counting. Compared with existing technologies, it has the advantages of high counting accuracy and high efficiency, and will not produce the phenomenon of too many or too few materials. However, in the use of high-accuracy counting structures in packaging machines, the space between the pusher structure and the feeding position is larger than the material. This makes it impossible to guarantee the amount of material falling into the space. When the material fills the space, the pusher plate will compact the material and prevent it from being conveyed, causing blockage of the high-accuracy counting structure in the packaging machine, affecting the normal feeding of the high-accuracy counting structure in the packaging machine. Utility Model Content

[0004] The purpose of this invention is to address the problem of blockage in high-accuracy counting structures used in packaging machines, which affects the normal feeding of these structures. This invention proposes a high-accuracy counting structure for packaging machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a high-accuracy counting structure for a packaging machine, comprising an outer shell and straight plates. The bottom left and right sides of the outer shell are fixedly connected to the inner sides of the two straight plates respectively. A feeding structure is connected to the inner wall of the outer shell. An opening and closing structure is connected to the top of the outer shell. Curved plates are fixedly connected to the top left side of the front and rear sides of the outer shell respectively. Bolts are threadedly connected to the top front and rear sides of the straight plates respectively.

[0007] Preferably, the feeding structure includes a round rod and a motor. The front and rear sides of the outer wall of the round rod are rotatably connected to the front and rear sides of the inner wall of the outer shell, respectively. The front side of the round rod is fixedly connected to the output shaft of the motor. A cylinder is fixedly connected to the outer wall of the round rod. Curved blocks are adjacent to the left and right sides of the outer wall of the cylinder, and the outer walls of the curved blocks are fixedly connected to the inner wall of the outer shell.

[0008] Preferably, a bracket is fixedly connected to the top of the motor, and the rear end face of the bracket is fixedly connected to the front face of the housing.

[0009] Preferably, the opening and closing structure includes a top plate and a curved plate. The bottom outer side of the top plate is attached to the top of the outer shell. The right side of the top plate is fixedly connected to the left side of the curved plate. A screw is rotatably connected to the inner wall of the curved plate. A nut is threadedly connected to the lower part of the outer wall of the screw. A slotted plate is inserted into the outer wall of the screw. The left side of the slotted plate is fixedly connected to the top right side of the outer shell.

[0010] Preferably, the left side of the outer wall of the top plate is rotatably connected to the upper inner side of the curved plate.

[0011] Preferably, a protective pad is fixed to the inner wall of the top plate.

[0012] The present invention proposes a high-accuracy counting structure for packaging machines, which has the following advantages: When the motor in the feeding structure is powered on, the motor output shaft drives the round rod to rotate, and the rotating round rod drives the cylinder to rotate. The granular material in the groove on the outer wall of the rotating cylinder rotates along with it. When the cylinder rotates to the bottom, the granular material inside the groove falls downward and enters the packaging machine for packaging. At this time, the grooves in other positions on the outer wall of the cylinder rotate to the top, and the granular material inside the outer shell enters the groove for collection. This avoids clogging of the high-accuracy counting structure for packaging machines and ensures normal feeding of the high-accuracy counting structure for packaging machines.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Please see Figure 1-5 In this embodiment, a high-accuracy counting structure for a packaging machine includes a housing 1 and a straight plate 4. The bottom of the left and right sides of the housing 1 are respectively fixed to the inner sides of the two straight plates 4. The inner wall of the housing 1 is connected to a feeding structure 2. The top of the housing 1 is connected to an opening and closing structure 3. The left side of the top of the front and rear sides of the housing 1 is respectively fixed to a curved plate 6. The front and rear sides of the top of the straight plate 4 are respectively threaded with bolts 5.

[0021] The feeding structure 2 includes a round rod 201 and a motor 202. The front and rear sides of the outer wall of the round rod 201 are rotatably connected to the front and rear sides of the inner wall of the outer shell 1, respectively. The round rod 201 rotates under force through the sealed bearings on the front and rear sides of the inner wall of the outer shell 1. The front side of the round rod 201 is fixedly connected to the output shaft of the motor 202. The motor 202 is a servo motor. A cylinder 203 is fixedly connected to the outer wall of the round rod 201. There are curved blocks 204 adjacent to the left and right sides of the outer wall of the cylinder 203. The outer wall of the curved blocks 204 is fixedly connected to the inner wall of the outer shell 1. A bracket 7 is fixedly connected to the top of the motor 202. The bracket 7 supports the motor 202 and ensures the stability of the motor 202 during operation. The rear end face of the bracket 7 is fixedly connected to the front side of the outer shell 1.

[0022] When the motor 202 in the feeding structure 2 is powered on, the output shaft of the motor 202 drives the round rod 201 to rotate, and the rotating round rod 201 drives the cylinder 203 to rotate. The granular material in the groove on the outer wall of the rotating cylinder 203 rotates along with it. When the cylinder 203 rotates to the bottom, the granular material inside the groove falls downward and enters the packaging machine for packaging. At this time, the grooves in other positions on the outer wall of the cylinder 203 rotate to the top, and the granular material inside the outer shell 1 enters the groove for collection. This avoids clogging of the high-accuracy counting structure of the packaging machine and ensures the normal feeding of the high-accuracy counting structure of the packaging machine.

[0023] The opening and closing structure 3 includes a top plate 301 and a curved plate 302. The bottom outer side of the top plate 301 is attached to the top of the outer shell 1. The right side of the top plate 301 is fixedly connected to the left side of the curved plate 302. A screw 303 is rotatably connected to the inner wall of the curved plate 302. The upper part of the outer wall of the screw 303 is rotated through a pin on the inner wall of the curved plate 302 under force. A nut 304 is threadedly connected to the lower part of the outer wall of the screw 303. The nut 304 rotates up and down through the outer wall of the screw 303 under force. A slotted plate 305 is inserted into the outer wall of the screw 303. The left side of the slotted plate 305 is fixedly connected to the top right side of the outer shell 1. The left side of the outer wall of the top plate 301 is rotatably connected to the upper inner side of the curved plate 6. The left side of the outer wall of the top plate 301 is rotated through a pin on the upper inner side of the curved plate 6 under force. A protective pad 8, which is a rubber plate, is fixedly connected to the inner wall of the top plate 301.

[0024] Working principle:

[0025] Preparation for installing a high-accuracy counting structure for packaging machines:

[0026] Align the bottom of the outer casing 1 with the material inlet on the top of the packaging machine. At this point, the bottom of the straight plate 4 is flush with the top of the packaging machine. Then, the bolt 5, threaded from top to bottom, passes through the straight plate 4 and connects to the round thread on the top of the packaging machine, completing the fixation of the straight plate 4 and the outer casing 1. Subsequently, the nut 304 rotates downward through the screw 303, causing the top of the nut 304 to disengage from the bottom of the groove plate 304. Next, the upper part of the outer wall of the screw 303, which is engaged with the inner wall of the curved plate 302, rotates to the right to disengage from the groove plate 305. Then, the outer wall of the top plate 301 rotates to the left. The side plate 6 is opened by rotating the pin shaft upwards through the inner wall of the bending plate 6. Then, the granular material (candy or plastic granules are produced by special equipment and the granules are basically the same size) is poured into the outer shell 1. Then, the top plate 301 rotates to press the inner wall pad 8 tightly against the top of the outer shell 1. Then, the screw 303 rotates downwards and inserts into the groove plate 305. Then, the nut 304 rotates upwards on the outer wall of the screw 303, so that the top of the nut 304 abuts against the bottom of the groove plate 305, thus completing the positioning of the screw 303 and the groove plate 305.

[0027] The packaging machine operates with a high-accuracy counting mechanism:

[0028] The outer wall of cylinder 203 has multiple grooves, and the granular materials are all the same size. Therefore, the grooves on the outer wall of cylinder 203 can hold the same amount of granular materials (there will be gaps when the granular materials are piled up, and a few extra materials may be placed, but it will not exceed the error value, thus improving the accuracy). When motor 202 is powered on, the output shaft of motor 202 drives the round rod 201 to rotate. The rotating round rod 201 drives the cylinder 203 to rotate. The granular materials in the grooves on the outer wall of cylinder 203 rotate along with it. When cylinder 203 rotates to the bottom, the granular materials inside the grooves fall downwards into the packaging machine for packaging. At this time, the grooves in other positions on the outer wall of cylinder 203 rotate to the top, and the granular materials inside the outer shell 1 enter the grooves for collection.

[0029] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
