Description

Technical Field

[0001] This utility model relates to the field of veterinary drug packaging equipment technology, and in particular to an intermittent bottle stop and capping device for veterinary drug filling. Background Technology

[0002] In the veterinary drug packaging process, after the veterinary drug liquid is filled into the veterinary drug bottle, a veterinary drug bottle capping device is used to install the cap onto the veterinary drug bottle. During this process, the filled veterinary drug bottle is transported downstream by a conveyor belt. The existing veterinary drug bottle capping device first places the cap one by one at the mouth of the veterinary drug bottle through a cap placement mechanism, and then tightens the cap through a capping mechanism. However, during the capping process, the veterinary drug bottle needs to pass through the capping mechanism one by one. The existing veterinary drug bottle capping device does not have a stop mechanism, which causes the veterinary drug bottles to accumulate upstream of the cap placement mechanism and the capping mechanism. An additional sensing device is required, and the sensing device needs to cooperate with the capping mechanism to determine the position of the veterinary drug bottle in order to accurately clamp the veterinary drug bottle and perform the capping action, which has poor reliability.

[0003] Therefore, there is a need for an intermittent bottle stop and capping device for veterinary drug filling that solves the above problems. Utility Model Content

[0004] This utility model proposes an intermittent bottle-stopping and capping device for veterinary drug filling. Through the cooperation of a cam, a swing arm and a locking plate, the limiting rod intermittently blocks the veterinary drug bottle, so that the veterinary drug bottle passes through the capping mechanism and the capping mechanism one by one at a certain distance, thereby improving the reliability of the capping device.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An intermittent bottle-stopping and capping device for veterinary drug filling includes a frame. A conveying mechanism for transporting veterinary drug bottles forward is mounted on the frame. Along the forward direction of the veterinary drug bottles, a stopping mechanism, a capping mechanism, and a capping mechanism are sequentially mounted on the frame. The stopping mechanism includes a rotating shaft rotatably mounted on the frame. The rotating shaft is vertically oriented. A plurality of limiting rods for intermittently blocking the forward movement of the veterinary drug bottles are fixedly mounted on the upper end of the rotating shaft. The limiting rods are horizontally oriented and radially evenly distributed on the rotating shaft. A locking disc is fixedly mounted on the rotating shaft. A plurality of locking grooves are evenly distributed on the outer circumference of the locking disc. A swing arm is hinged to the frame. A locking block adapted to the locking grooves is fixedly mounted on the free end of the swing arm. A tension spring for bringing the locking block closer to the locking disc is provided between the frame and the swing arm. A cam that abuts against the inner side of the swing arm is rotatably mounted on the frame.

[0007] As a preferred technical solution, the conveying mechanism includes a driving synchronous pulley and a driven synchronous pulley rotatably mounted on the frame, a conveyor belt is provided between the driving synchronous pulley and the driven synchronous pulley, two baffles are fixedly installed on the frame, the two baffles are positioned above the conveyor belt, and the veterinary drug bottle is positioned between the two baffles.

[0008] As a preferred technical solution, the cap-dispensing mechanism includes a cap slide groove with an open bottom. The cap slide groove is fixedly installed on the frame and is inclined. The lower end of the cap slide groove is provided with a cap outlet. First elastic limiting plates for limiting the two sides of the cap are fixedly installed on both sides of the cap outlet, and a second elastic limiting plate for limiting the top of the cap is fixedly installed on the top of the cap outlet.

[0009] As a preferred technical solution, the capping mechanism includes a pair of clamping plates for holding the veterinary drug bottle. The two clamping plates are slidably mounted on the frame in the horizontal direction. A support frame is provided on the frame, and two sliding plates are slidably mounted on the support frame in the horizontal direction. Two vertically arranged rotating shafts are rotatably mounted on each sliding plate. The two rotating shafts are connected by a drive. A damping wheel for tightening the bottle cap is fixedly mounted on each rotating shaft. A pressure plate is provided between the two sliding plates, and the pressure plate is slidably mounted on the support frame in the vertical direction.

[0010] As a preferred technical solution, a horizontally arranged guide column is fixedly installed on the support frame, and both sliding plates are slidably installed on the guide column. Two sliding plate drive cylinders are fixedly installed on the support frame, and the piston rod of each sliding plate drive cylinder passes through the support frame and is fixedly connected to the corresponding sliding plate. This is an intermittent veterinary drug bottle stop-stop capping device for veterinary drug filling.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0012] Because the intermittent bottle stop and capping device for veterinary drug filling includes a stop mechanism, a cap placement mechanism, and a capping mechanism, in engineering projects using this device, the filled veterinary drug bottles are conveyed by the conveying mechanism and pass through the stop mechanism, the cap placement mechanism, and the capping mechanism in sequence. The stop mechanism intermittently blocks the veterinary drug bottles by a limit rod, causing the veterinary drug bottles to pass through the cap placement mechanism and the capping mechanism one by one at a certain distance, so that the caps are placed on the veterinary drug bottles one by one. The veterinary drug bottles with caps are then passed through the capping mechanism one by one, and the caps are tightened on the veterinary drug bottles, thus realizing the automatic capping of veterinary drug bottles.

[0013] Because the intermittent bottle-stopping and capping device for veterinary drug filling includes a stopping mechanism, as a train of veterinary drug bottles moves downstream, when the first bottle passes the stopping mechanism, it is blocked by a limit rod. The cam rotates, and the proximal end of the cam abuts against the swing arm, causing the locking block to move out of the limiting groove. The locking disc unlocks, and under the conveying mechanism, the first bottle moves forward and pushes the limit rod to rotate. When the first bottle moves between the two limit rods located above the conveying mechanism, the second bottle moves to the original position of the first bottle. At this time, the proximal end of the cam abuts against the swing arm, and under the action of the tension spring, the limit block moves to the other position. Within the limiting groove, the locking disc is unlocked. As the cam continues to rotate, the locking disc unlocks again, and the first veterinary drug bottle disengages from the stopping mechanism and moves downstream, passing sequentially through the capping mechanism and the screwing mechanism. At this point, the second veterinary drug bottle moves between the two limiting rods located above the conveying mechanism, and the third veterinary drug bottle moves back to the original position of the second bottle. As the cam continues to rotate, the second veterinary drug bottle disengages from the stopping mechanism and moves downstream sequentially. At this point, the third veterinary drug bottle moves between the two limiting rods located above the conveying mechanism, and the fourth veterinary drug bottle moves back to the original position of the third bottle. This process repeats, intermittently blocking the veterinary drug bottles.

[0014] In this invention, the swing arm is driven by the cam to swing, and the locking plate is intermittently locked by the cooperation of the locking block and the locking groove. This causes the limiting rod to intermittently block the veterinary drug bottles, allowing the veterinary drug bottles to be transported downstream one by one at a certain distance. This ensures the continuity of the veterinary drug production line. Compared with existing devices, this invention avoids the accumulation of veterinary drug bottles at the capping mechanism and the screwing mechanism, thus improving the reliability of the equipment.

[0015] Because the intermittent bottle stop and capping device for veterinary drug filling includes a cap placement mechanism, which includes an inclined cap groove, so that the cap at the outlet is inclined, when the veterinary drug bottle passes the outlet under the conveying mechanism, the bottle mouth of the veterinary drug bottle will abut against the inside of the cap at the outlet. As the veterinary drug bottle moves forward, the bottle mouth of the veterinary drug bottle pulls the cap out from the outlet. After being pulled out, the cap falls down and covers the bottle mouth. The upper cap moves down to the outlet under the action of gravity and is limited by the first elastic limiting piece and the second elastic limiting piece at the outlet, preparing for the next cap placement. In this utility model, the forward veterinary drug bottle will pull out the cap at the outlet, and the pulled-out cap will automatically cover the veterinary drug bottle, thus realizing automatic capping.

[0016] Because the intermittent bottle stop and capping device for veterinary drug filling includes a capping mechanism, the veterinary drug bottle with the cap is passed through the capping mechanism at a certain distance by the stop mechanism. The veterinary drug bottle is clamped and fixed by two clamping plates, and the pressure plate presses against the top of the cap. Under the drive of the sliding plate drive cylinder, both sliding plates move towards the cap, so that the four damping wheels abut against the side of the cap. The cap is tightened on the veterinary drug bottle by the rotation of the four damping wheels. After tightening, the damping wheels, pressure plate and clamping plate are reset to prepare for the next capping. In this utility model, the tightening of the cap is realized one by one by the cooperation of the two clamping plates, four damping wheels and pressure plate. Attached Figure Description
