Description

Technical Field

[0001] The present invention relates to the technical field of checkweighers, and in particular to a sliding transmission type automatic checkweigher. Background Art

[0002] A checkweigher, also known as a weight checker or weight sorter, is a device used on production lines for high-speed, high-precision weight checks and automatic sorting of underweight or overweight products. This equipment significantly improves product quality and optimizes production processes, thereby controlling costs, eliminating waste, and increasing profits. Checkweighers are widely used in the pharmaceutical, food, and chemical industries. They can detect overweight or underweight products in real time, ensuring that manufacturers' products fully comply with national regulations, including standard weights or accessories, while also ensuring consumers receive a verified, high-quality product.

[0003] When checking the weight of spherical objects, in order to prevent the objects from rolling, a special tray needs to be designed to limit the position of the spheres. In the existing technology, the spheres are generally placed on the tray for check weighing by hand, which is relatively inefficient. The spheres are rolled onto the check weighing scale by a machine. Since the position of the spheres on the check weighing scale is not fixed, the test results are inaccurate. Equipping each sphere with a special tray increases the cost of check weighing. Summary of the Invention

DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example:

[0037] See also Figures 1-8 The present invention provides a technical solution: a sliding transmission automatic checkweigher, comprising:

[0038] A working platform 1, with at least one set of checkweigher bodies 11 provided on one side above the working platform 1, and a limiting mechanism corresponding to the checkweigher bodies 11 provided above the working platform 1;

[0039] The limiting mechanism includes a tray 21. The side of the tray 21 close to the checkweigher body 11 is open. A groove is formed inside the tray 21. The inner upper surface of the tray 21 is inclined. A support plate 24 is provided on the side of the tray 21 away from the checkweigher body 11. A moving component that can drive the support plate 24 toward or away from the checkweigher body 11 is provided on the side of the support plate 24 away from the tray 21.

[0040] Among them, the side of the tray 21 close to the checkweigher body 11 and the support plate 24 are magnetic and attract each other. Two sets of clamps 22 are slidably inserted into the interior of the tray 21. The two sets of clamps 22 are respectively located on both sides of the tray 21. An adjustment component that can drive the two sets of clamps 22 to move closer or farther away from each other is provided between the two sets of clamps 22 and the support plate 24. A plurality of groups of balls 23 are provided on the adjacent sides of the two sets of clamps 22. The balls 23 are in contact with both sides of the tray 21.

[0041] A material unloading mechanism is provided below the working platform 1 and can drive the tray 21 to rotate.

[0042] Specifically, the adjustment component includes a support frame 31, which is slidably installed on the side of the support plate 24 away from the tray 21. A push block 32 is slidably installed above the support frame 31 through a slide rail. Connecting plates 33 are rotatably installed on both sides of the push block 32 through a rotating seat. The ends of the two groups of connecting plates 33 away from the push block 32 are rotatably connected through the rotating seat and the two groups of clamps 22 close to the support frame 31.

[0043] A lifting structure is provided above the support frame 31, which can drive the support plate 24 to move up and down. The lifting structure includes a push plate 41, a push rod 42 and a support block 43. The push plate 41 is slidably installed above the support frame 31 through a slide rail. One end of the push rod 42 is rotatably connected to the push plate 41 through a mounting seat, and the other end of the push rod 42 is rotatably connected to the push block 32 through a mounting seat. The support block 43 is fixedly installed on the side of the push block 32 close to the support plate 24. A card slot is provided on the side of the support plate 24 close to the push block 32 to cooperate with the support block 43. The support block 43 is magnetic and the support block 43 and the support plate 24 are attracted to each other.

[0044] The moving assembly includes a fixed plate 51 and an adjusting plate 52. The fixed plate 51 is arranged between the adjusting plate 52 and the support plate 24. An elastic member 53 is provided between the fixed plate 51 and the adjusting plate 52. The fixed plate 51 is fixedly connected to the support frame 31. The adjusting plate 52 is fixedly connected to the push plate 41. A limit plate 54 is fixedly installed on one side of the working platform 1 close to the checkweigher body 11. The limit plate 54 is in contact with the fixed plate 51. A driving member is provided on the side of the adjusting plate 52 away from the fixed plate 51.

[0045] The driving member is a hydraulic rod 6, which is fixedly mounted above the working platform 1 on a side away from the checkweigher body 11. The hydraulic rod 6 is arranged horizontally, and the output end of the hydraulic rod 6 is fixedly connected to the side of the adjustment plate 52 away from the fixed plate 51.

[0046] The sphere is placed inside the groove above the tray 21, and the hydraulic rod 6 is connected to an external power supply. The hydraulic rod 6 drives the adjustment plate 52 to move closer to or away from the direction of the checkweigher body 11 above the work platform 1. Under the action of the elastic member 53, the adjustment plate 52 can drive the fixed plate 51 to move synchronously (it should be noted that the elastic member 53 is composed of a rod and a spring, the rod and the fixed plate 51 are fixedly connected, and the rod slides through the adjustment plate 52, the spring is movably sleeved on the outside of the rod, and the spring is located between the fixed plate 51 and the adjustment plate 52), the fixed plate 51 and the support frame 31 are fixedly connected, and when the fixed plate 51 moves, it can drive the support plate 24 and the tray 21 to move synchronously through the support frame 31.

[0047] When the fixed plate 51 moves, it contacts the limit plate 54 and stops moving. At this time, the clamp 22 drives the tray 21 to move above the checkweigher body 11, and the hydraulic rod 6 drives the adjusting plate 52 to continue moving. The distance between the adjusting plate 52 and the fixed plate 51 gradually decreases, and the adjusting plate 52 can drive the push plate 41 to slide above the support frame 31. Under the action of the push rod 42, the push plate 41 can drive the push block 32 to move along the guide rail on the surface of the support frame 31. When the push block 32 moves in the direction of the support frame 31, the push block 32 drives the two groups of clamps 22 away from each other inside the support plate 24 through the connecting plate 33. At this time, the clamp 22 is separated from the tray 21, and the tray 21 can drive the ball to fall above the checkweigher body 11 under the action of gravity.

[0048] Furthermore, as the push block 32 continues to approach the support plate 24, the push block 32 can drive the support block 43 to insert into the slot opened on the support plate 24. Since the support plate 24 and the support block 43 are both magnetic and attract each other, when the support block 43 is inserted into the slot, the support plate 24 can be tightly connected to the support block 43. At this time, the push block 32 is separated from the guide rail on the support frame 31, and the push plate 41 continues to move toward the direction of the support plate 24. The push plate 41 can drive the push rod 42 to rotate, so that the push rod 42 can drive the support plate 24 to move upward on the outer surface of the support frame 31, thereby further reducing the influence of the clamp 22 and the support plate 24 on the tray 21, and ensuring the accuracy of the detection results.

[0049] After the detection of the sphere is completed, the adjustment plate 52 drives the fixed plate 51 to move in the direction away from the weighing scale body 11. The support plate 24 and the support block 43 are magnetic and attract each other. Therefore, when the push plate 41 moves in the direction away from the support plate 24, the support plate 24 can move downward along the outer surface of the support frame 31. When the support plate 24 moves to above the weighing scale body 11, the support plate 24 stops moving. Since the support plate 24 and the tray 21 are attracted to each other, the tray 21 can fit tightly with the support plate 24. At the same time, the push plate 41 can pull the push block 32 to move in the direction away from the support plate 24. The push block 32 drives the two groups of clamps 22 away from each other through the two groups of connecting plates 33, and the clamps 22 clamp the tray 21.

[0050] Furthermore, a storage slot 81 is provided between the checkweigher body 11 and the tray 21. The storage slot 81 is slidably connected to the work platform 1 through a guide rail. The storage slot 81 opens to the tray 21. The inner upper end surface of the storage slot 81 is inclined away from the side of the tray 21. The side of the clamp 22 close to the storage slot 81 is provided with a toggle structure that can toggle the ball into the inside of the tray 21. A power structure that can drive the storage slot 81 to move up and down is provided between the storage slot 81 and the fixed plate 51.

[0051] The toggle structure includes a toggle plate 71 and a rotating shaft 72. The toggle plate 71 is rotatably mounted on the side of the clamp 22 close to the storage slot 81 through the rotating shaft 72. The rotating shaft 72 is arranged in a vertical shape. The fixed sleeve on the circumferential outer surface of the rotating shaft 72 is provided with a gear 73. The lower surface of the clamp 22 is fixedly mounted with a slide rod 75. The outer surface sliding sleeve of the slide rod 75 is provided with a rack 74 that is slidably connected to the clamp 22. The rack 74 is in contact with the storage slot 81, and the rack 74 is meshed with the gear 73. The movable sleeve on the circumferential outer surface of the slide rod 75 is provided with a reset spring 76, and the reset spring 76 is fixedly connected to the rack 74.

[0052] The power structure includes a vertical plate 82, which is fixedly installed under the working platform 1. The vertical plate 82 contacts one side of the opening of the storage groove 81 and is fixedly inserted with a cross bar 83 on both sides of the working platform 1. The cross bar 83 is arranged horizontally, and the sliding sleeve on the circumferential outer surface of the cross bar 83 is provided with a mounting block 84 that is slidably connected to the working platform 1. The sliding sleeve on the circumferential outer surface of the cross bar 83 is provided with a coil spring 85, and the coil spring 85 is fixedly connected to the mounting block 84. The lower surface of the mounting block 84 is rotatably installed with a connecting rod 86 through a mounting seat, and the end of the connecting rod 86 away from the mounting block 84 is rotatably connected to the lower end of the storage groove 81 through the mounting seat.

[0053] The spheres to be tested are placed inside the storage slot 81. In the initial state, the storage slot 81 is located between the tray 21 and the checkweigher body 11, and the storage slot 81 is above the work platform 1. When the tray 21 moves toward the storage slot 81, the rack 74 contacts the protruding portion in the middle of the upper surface of the storage slot 81. As the clamp 22 continues to move, the rack 74 can move on the circumferential outer surface of the slide bar 75 away from the storage slot 81. At this time, the reset spring 76 is compressed. Since the gear 73 and the rack 74 are engaged, the rack 74 can drive the rotating shaft 72 to rotate through the gear 73 when moving. The rotating shaft 72 drives the dial plate 71 to rotate, and the dial plate 71 can gather the spheres inside the storage slot 81 to the top of the tray 21.

[0054] The fixed plate 51 continues to move above the working platform 1, and the fixed plate 51 contacts the mounting block 84 and drives the mounting block 84 to slide on the circumferential outer surface of the cross bar 83. At this time, the coil spring 85 is deformed by the force, and the mounting block 84 drives the storage slot 81 to move downward through the connecting rod 86. Under the action of the vertical plate 82, when the storage slot 81 moves to the bottom of the working platform 1, the balls inside the storage slot 81 will not roll out through the opening.

[0055] Furthermore, when the rack 74 is separated from the storage groove 81, under the action of the reset spring 76, the reset spring 76 drives the paddle 71 to reset through the rack 74, and the two sets of paddles 71 are in an open state. Since the inner upper surface of the tray 21 is inclined, the balls that fall into the groove are processed, and the other balls can fall into the storage groove 81 along the surface of the tray 21, so that only one ball is left inside the tray 21 for weight inspection.

[0056] The ball that falls into the storage slot 81 can roll to the side of the storage slot 81 away from the checkweigher body 11 because the side of the storage slot 81 close to the checkweigher body 11 is inclined, making it easier for the tray 21 to take the material from the storage slot 81 again.

[0057] It should be noted that when the fixing plate 51 moves away from the checkweigher body 11, under the action of the coil spring 85, the coil spring 85 drives the mounting block 84 to move away from the checkweigher body 11. At this time, the storage slot 81 can be moved to the top of the work platform 1 again.

[0058] Furthermore, the unloading mechanism includes a unloading port 91, a driven shaft 92 and a driving shaft 94. The unloading port 91 is opened on the side of the working platform 1 close to the checkweigher body 11. The driven shaft 92 is rotatably inserted into the inside of the unloading port 91. The driving shaft 94 is rotatably inserted into the inside of the working platform 1 on the side of the driven shaft 92 away from the checkweigher body 11. The external movable sleeve of the driving shaft 94 and the driven shaft 92 is provided with a crawler 95. A protrusion 96 is fixedly installed above the circumferential outer surface of the driving shaft 94. The protrusion 96 is in contact with the fixed plate 51. A protrusion 93 is fixedly installed above the circumferential outer surface of the driven shaft 92 close to the side of the checkweigher body 11. The external movable sleeve of the driven shaft 92 is provided with a torsion spring 97 fixedly connected to the working platform 1.

[0059] The tray 21 drives the ball that has been tested to move away from the checkweigher body 11. The fixed plate 51 contacts the protrusion 96 during the movement and drives the driving shaft 94 to rotate through the protrusion 96. Under the action of the crawler 95, the driving shaft 94 can drive the driven shaft 92 to rotate synchronously. At this time, the protrusion 93 rotates to the top of the working platform 1. At this time, the protrusion 93 is located on the side of the bottom of the tray 21 close to the support plate 24. When the protrusion 93 rotates, with the cooperation of the ball 23, it can drive the multi-functional tray 21 to rotate, so that the ball above the tray 21 can fall into the inside of the discharge port 91 and be discharged through the discharge port 91.

[0060] It should be noted that when the fixed plate 51 moves toward the checkweigher body 11, the contact between the fixed plate 51 and the protrusion 96 can drive the active shaft 94 to rotate toward the checkweigher body 11. At this time, the driven shaft 92 drives the protrusion 93 to rotate synchronously, and the protrusion 93 rotates toward the bottom of the work platform 1 without contacting the tray 21. When the fixed plate 51 is separated from the protrusion 96, under the action of the torsion spring 97, it can ensure that the protrusion 96 is always located above the active shaft 94.

[0061] The process of checkweighing:

[0062] The sphere to be tested is placed inside the storage slot 81, which is above the work platform 1. The hydraulic rod 6 drives the adjustment plate 52 to move closer to or away from the direction of the checkweigher body 11 above the work platform 1. Under the action of the elastic member 53, the adjustment plate 52 can drive the fixed plate 51 to move synchronously. The fixed plate 51 is fixedly connected to the support frame 31. When the fixed plate 51 moves, it can drive the support plate 24 and the tray 21 to move synchronously through the support frame 31.

[0063] When the tray 21 moves toward the storage slot 81, the rack 74 contacts the protruding portion in the middle of the upper surface of the storage slot 81. As the clamp 22 continues to move, the rack 74 can move on the circumferential outer surface of the slide bar 75 in the direction away from the storage slot 81. At this time, the return spring 76 is compressed. When the rack 74 moves, the rotating shaft 72 is driven to rotate through the gear 73. The rotating shaft 72 drives the dial plate 71 to rotate. The dial plate 71 can gather the spheres inside the storage slot 81 to the top of the tray 21.

[0064] The fixed plate 51 continues to move above the working platform 1, and the mounting block 84 of the fixed plate 51 slides. At this time, the coil spring 85 is deformed by the force, and the mounting block 84 drives the storage slot 81 to move downward through the connecting rod 86. Under the action of the vertical plate 82, when the storage slot 81 moves to the bottom of the working platform 1, the balls inside the storage slot 81 will not roll out through the opening.

[0065] When the rack 74 is separated from the storage groove 81, under the action of the reset spring 76, the reset spring 76 drives the paddle 71 to reset through the rack 74, and the two sets of paddles 71 are in an open state. Since the inner upper surface of the tray 21 is inclined, the balls that fall into the groove are processed, and the other balls can fall into the storage groove 81 along the surface of the tray 21, so that only one ball is left inside the tray 21 for weight check.

[0066] The clamp 22 drives the tray 21 to move above the checkweigher body 11. Under the action of the limit plate 54, the fixed plate 51 stops moving, and the hydraulic rod 6 drives the adjusting plate 52 to continue moving. The distance between the adjusting plate 52 and the fixed plate 51 gradually decreases, and the adjusting plate 52 can drive the push plate 41 to slide above the support frame 31. Under the action of the push rod 42, the push plate 41 can drive the push block 32 to move along the guide rail on the surface of the support frame 31. The push block 32 drives the two groups of clamps 22 away from each other inside the support plate 24 through the connecting plate 33. At this time, the clamp 22 is separated from the tray 21, and the tray 21 can drive the ball to fall above the checkweigher body 11 under the action of gravity.

[0067] As the push block 32 continues to approach the support plate 24, the push block 32 is inserted into the slot opened on the support plate 24, and the push plate 41 continues to move toward the support plate 24. The push plate 41 can drive the push rod 42 to rotate, so that the push rod 42 can drive the support plate 24 to move upward on the outer surface of the support frame 31.

[0068] After the detection of the sphere is completed, the adjustment plate 52 drives the fixed plate 51 to move in the direction away from the weighing scale body 11. The support plate 24 and the support block 43 are magnetic and attract each other. Therefore, when the push plate 41 moves in the direction away from the support plate 24, the support plate 24 can move downward along the outer surface of the support frame 31. When the support plate 24 moves to above the weighing scale body 11, the support plate 24 stops moving. Since the support plate 24 and the tray 21 are attracted to each other, the tray 21 can fit tightly with the support plate 24. At the same time, the push plate 41 can pull the push block 32 to move in the direction away from the support plate 24. The push block 32 drives the two groups of clamps 22 away from each other through the two groups of connecting plates 33, and the clamps 22 clamp the tray 21.

[0069] The tray 21 drives the ball that has been tested to move away from the checkweigher body 11. The fixed plate 51 contacts the protrusion 96 during the movement and drives the driving shaft 94 to rotate through the protrusion 96. Under the action of the crawler 95, the driving shaft 94 can drive the driven shaft 92 to rotate synchronously. At this time, the protrusion 93 rotates to the top of the working platform 1. At this time, the protrusion 93 is located on the side of the bottom of the tray 21 close to the support plate 24. When the protrusion 93 rotates, with the cooperation of the ball 23, it can drive the multi-functional tray 21 to rotate, so that the ball above the tray 21 can fall into the inside of the discharge port 91 and be discharged through the discharge port 91.
