Technical Field
[0001] The utility model relates to the technical field of checkweighers, in particular to an earthquake-resistant packaging checkweigher. Background Art
[0002] An innovatively designed, seismic-resistant packaging checkweigher was developed based on a deep understanding of the stringent weight control requirements in the production and packaging processes of numerous industries, including food, pharmaceuticals, and daily chemicals. Ensuring that every packaged product complies with established production standards and metrology regulations is crucial in these industries. This not only impacts product quality but is also crucial for safeguarding consumer rights and corporate reputation. Therefore, automated weight checking is an essential component. By accurately weighing products within a preset acceptable weight range, it effectively distinguishes between compliant products and unqualified overweight or underweight products, ensuring that only products that meet quality requirements enter the market.
[0003] However, traditional checkweighers face a challenge in practical application: when items are transferred from the conveyor belt to the checkweigher platform, there is often a certain vertical height difference (height difference) between the two. This physical change may cause the items to be impacted at the moment of contact. This may not only cause damage to the items themselves, such as packaging damage and deformation, but may also cause wear and tear on the precision measuring components of the checkweigher, affecting its long-term accuracy and stability.
[0004] To address this common problem, we have proposed a new shock-resistant packaging checkweigher solution. This solution aims to effectively alleviate the impact force during item transportation and protect the safety of products and equipment through a series of innovative designs. Utility Model Content

After the clamping component 4 and the article are moved above one of the conveying devices 1, the controller controls the motor to stop running, and then controls the electric push rod 1 42 to run, and uses the piston rod of the electric push rod 1 42 to drive the support plate 1 44 to move downward. Then, when the lower end of the article contacts the conveyor belt surface on the conveying device 1, the electric push rod 1 42 is controlled to stop running, and then controls the electric push rod 2 48 to run, so that the piston rod on the electric push rod 2 48 is retracted, and then drives the two clamps 47 to move in the direction away from the article, and then places the article on the transmission belt surface, and transports the article to the next process through another conveying device 1.
[0045] The working principle of the earthquake-resistant packaging checkweigher is described in detail below.
[0046] like Figures 1-9 As shown, when an item needs to be weighed, the item is first conveyed to a plurality of rollers 551 through one of the conveying devices 1, and then the electric push rod 3 54 is controlled by the controller to operate. When the piston rod of the electric push rod 3 54 contracts, the contact with the slider 2 552 is released. Then, without the support of the electric push rod 3 54, the weight of the item drives the placement rack 55 to move downward, and then drives the slider 2 552 to move downward in the inner cavity of the chute 2 562, and drives the slider 3 553 to move downward in the inner cavity of the chute 1 561. When the placement rack 55 drops to a certain height, the lower end of the placement rack 55 contacts the upper end of the partition 53, and then the item can be weighed by the checkweigher body 52.
[0047] After the items are weighed, the controller controls the electric push rod 3 54 to operate, and then the piston rod output end of the electric push rod 3 54 will extend upward, and then the piston rod output end of the electric push rod 3 54 will contact the slider 2 552, which will drive the slider 2 552 to move upward together, and then the slider 2 552 will drive the placement rack 55 and the items placed on the plurality of rollers 551 to move upward together. When the upper end of the slider 2 552 contacts the top wall of the inner cavity of the slide groove 2 562, the electric push rod 3 54 stops operating, and then the controller controls the electric push rod 2 48 to operate, and the piston rod of the electric push rod 2 48 is used to push the clamping plate 47 to move toward the direction of the items, and then with the cooperation of the two clamping plates 47, the items will be clamped. Then, the controller controls the electric push rod 1 42 to operate, and the piston rod of the electric push rod 1 42 is used to drive the support plate 1 44 to move upward, and then the slider 1 46 will be driven to move upward in the inner cavity of the connecting block 43. When the support plate 1 44 moves upward, it will drive the items clamped by the clamping plate 47 to move upward together.
[0048] When the item is moved to a suitable height, the item is clamped and placed on the conveying device 1 according to its weight. Then, the motor is controlled by the controller to operate, and the motor is used to drive the threaded rod 2 34 to rotate. Then, with the cooperation of the threaded rod 2 34 and the connecting plate 4 41, the connecting plate 4 41 is driven to move. When the connecting plate 4 41 moves, the entire clamping assembly 4 is driven to move together, and then the item can be driven to move. Then, the motor is controlled by the controller to operate, and the motor is used to drive the threaded rod 1 23 to rotate. Then, with the cooperation of the threaded rod 1 23 and the connecting plate 2 31, the connecting plate 2 31 can be driven to move toward the direction of the other first moving assembly 2 conveying device 1. Then, when the connecting plate 2 31 moves, the clamping assembly is driven 4 and the article move together toward the other two conveying devices 1 of the first moving component. After the clamping component 4 and the article are moved above one of the conveying devices 1, the controller controls the motor to stop running, and then controls the electric push rod 1 42 to run, and uses the piston rod of the electric push rod 1 42 to drive the support plate 1 44 to move downward. Then, when the lower end of the article contacts the conveyor belt surface on the conveying device 1, the electric push rod 1 42 is controlled to stop running, and then controls the electric push rod 2 48 to run, so that the piston rod on the electric push rod 2 48 is retracted, and then drives the two clamping plates 47 to move in the direction away from the article, and then places the article on the transmission belt surface, and conveys the article to the next process through another conveying device 1.

[0050] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
