Description

Technical Field

[0001] This application relates to the technical field of pharmaceutical manufacturing, and in particular to an intermittent feeding device. Background Technology

[0002] After capsule production, they are typically placed in a feeding hopper and then transported to the packaging area. A horizontal receiving hopper is installed at the bottom of the feeding hopper, with a discharge port at the end furthest from the feeding hopper. Below the discharge port, a conveyor hopper with a bottom wall sloping downwards towards the side furthest from the receiving hopper is installed. During transport, the capsules move through the opening at the bottom of the feeding hopper into the receiving hopper, and then along the length of the receiving hopper to the discharge port. From there, they move downwards through the discharge port into the conveyor hopper and continue to be transported along the sloping bottom wall of the conveyor hopper.

[0003] As the capsules move downwards from the discharge port to the conveyor hopper, a large number of capsules may accumulate at the discharge port, making it difficult to discharge the capsules. This requires manual cleaning of the clogged capsules, which can easily increase labor costs. Utility Model Content

[0004] To reduce the potential increase in labor costs, this application provides an intermittent feeding device.

[0005] The intermittent feeding device provided in this application adopts the following technical solution:

[0006] An intermittent feeding device includes a feeding hopper, a receiving hopper installed below the feeding hopper, and a conveying hopper installed below the receiving hopper at one end away from the feeding hopper. The receiving hopper has a feeding port on its lower side at the end away from the feeding hopper. A vibrating plate with its sidewall in contact with the sidewall of the receiving hopper is provided at the feeding port. The upper side of the vibrating plate is hinged to the receiving hopper. The receiving hopper is provided with a vibration assembly for driving the vibrating plate to vibrate.

[0007] By adopting the above technical solution, the vibration component drives the vibration plate to vibrate back and forth along its own hinge end. At this time, the cross-sectional area of ​​the capsule through the feed port changes continuously, which facilitates feeding and makes it less likely for the capsule to accumulate at the feed port, reducing the possibility of manually cleaning the clogged capsules and thus reducing the possibility of increased labor costs.

[0008] Optionally, a drive shaft is provided and fixedly connected to the upper side of the vibrating plate. The ends of the drive shaft pass through the side wall of the receiving hopper and are rotatably connected to the receiving hopper. The vibration assembly includes a torsion spring sleeved on the end of the drive shaft and connecting the end of the drive shaft and the receiving hopper. The receiving hopper is provided with a vibrating element that drives the vibrating plate to rotate toward the feeding hopper. At this time, the torsion spring is deformed.

[0009] By adopting the above technical solution, the vibrating component drives the lower end of the vibrating plate to rotate towards the feeding hopper, and the torsion spring deforms. When the vibrating component stops driving the vibrating plate to rotate, the torsion spring recovers its deformation and drives the vibrating plate to reciprocate. Thus, the vibrating component and the torsion spring work together to drive the vibrating plate to vibrate back and forth, reducing the possibility of capsules accumulating at the feeding port, thereby reducing the possibility of increased labor costs.

[0010] Optionally, the vibrating element includes a vibrating block fixedly connected to the vibrating plate on the side away from the hopper. The end of the vibrating block away from the hopper is arc-shaped and passes through the side wall of the receiving hopper. A vibrating rod is slidably connected to the outer side wall of the receiving hopper. One end of the vibrating rod is bent towards the vibrating block and always in contact with the arc-shaped surface of the vibrating block, and presses the vibrating block towards the side of the hopper.

[0011] By adopting the above technical solution, the vibrating rod is driven to move back and forth. At this time, the bent end of the vibrating rod continuously squeezes the arc surface of the vibrating block and drives the vibrating block to move the vibrating plate closer to the hopper. The torsion spring cooperates with the vibrating rod and continuously drives the vibrating plate to reset, thereby making the vibrating plate vibrate back and forth, reducing the possibility of capsules accumulating at the discharge port, and thus reducing the possibility of increased labor costs.

[0012] Optionally, the end of the vibrating rod away from the vibrating block is hinged to a hinge rod, and a vibrating disc parallel to the length direction of the receiving bucket is provided on the lower side of the hinge rod. The end of the hinge rod away from the vibrating rod is hinged to the edge of the vibrating disc.

[0013] By adopting the above technical solution, the vibratory plate rotates continuously. When the vibratory plate rotates to the point where the end of the hinge rod is hinged to the vibratory plate and is located on the side of the vibratory plate axis away from the vibrating block, the bent end of the vibratory rod is located on the side of the vibrating block close to the vibratory plate. When the end of the hinge rod is hinged to the vibratory plate and is located on the side of the vibratory plate axis close to the vibrating block, the bent end of the vibratory rod is located on the side of the vibrating block away from the vibratory plate. This works in conjunction with the torsion spring to continuously drive the vibratory plate to vibrate, reducing the possibility of capsules accumulating at the discharge port.

[0014] Optionally, a feeding assembly is provided inside the receiving hopper and at one end near the feeding hopper.

[0015] By adopting the above technical solution, the capsules are fed from the feeding hopper to the receiving hopper at the end away from the feeding port. At this time, the feeding component moves the capsules that have entered the receiving hopper toward the feeding port, thereby controlling the number of capsules that move to the feeding port at a time and reducing the possibility of a large number of capsules moving to the feeding port and causing blockage.

[0016] Optionally, the feeding assembly includes a mounting shaft located on the side of the feeding hopper near the vibrating plate and rotatably connected to the bottom wall of the receiving hopper, and a plurality of feeding plates located in the receiving hopper and in contact with the bottom wall of the receiving hopper are fixedly connected to the side wall of the mounting shaft.

[0017] By adopting the above technical solution, the drive mounting shaft drives the dial plate to rotate. At this time, the capsule moves to the gap between the adjacent dial plates and moves to the discharge port under the drive of the dial plate. Thus, the number of capsules moving to the discharge port at one time is controlled by the gap between the adjacent dial plates, reducing the possibility of a large number of capsules moving to the discharge port and causing blockage.

[0018] Optionally, the lower end of the mounting shaft passes through the receiving hopper, a fixed shaft is installed at the center of the vibrating plate, and a connecting piece is provided between the end of the mounting shaft passing through the receiving hopper and the fixed shaft to connect the two.

[0019] By adopting the above technical solution, the connecting component connects the mounting shaft and the fixed shaft, so that when the dial plate moves the capsule to the discharge port, the vibrating plate vibrates continuously, further reducing the possibility of a large number of capsules clogging the discharge port.

[0020] Optionally, the connector includes a belt connecting the mounting shaft and the fixed shaft, with a motor mounted at the end of the fixed shaft.

[0021] By adopting the above technical solution, while the motor drives the fixed shaft to rotate the vibratory plate, the belt drives the mounting shaft to rotate with the fixed shaft. This causes the vibratory plate to vibrate continuously when the pusher moves the capsule to the feeding port, further reducing the possibility of a large number of capsules clogging the feeding port.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The vibrating component drives the lower end of the vibrating plate to rotate towards the hopper, causing the torsion spring to deform. When the vibrating component stops driving the vibrating plate to rotate, the torsion spring returns to its original deformation and drives the vibrating plate to reciprocate. Thus, through the cooperation of the vibrating component and the torsion spring, the vibrating plate is driven to vibrate back and forth, reducing the possibility of capsules accumulating at the discharge port.

[0024] 2. Drive the vibrating rod to move back and forth. At this time, the bent end of the vibrating rod continuously squeezes the arc surface of the vibrating block and drives the vibrating block to move the vibrating plate closer to the hopper. The torsion spring and the vibrating rod cooperate with each other and continuously drive the vibrating plate to reset, so that the vibrating plate vibrates back and forth, reducing the possibility of capsules accumulating at the discharge port.

[0025] 3. The drive mounting shaft drives the dial plate to rotate. At this time, the capsule moves to the gap between the adjacent dial plates and moves to the discharge port under the drive of the dial plate. Thus, the number of capsules that move to the discharge port at one time is controlled by the gap between the adjacent dial plates, reducing the possibility of a large number of capsules moving to the discharge port and causing blockage.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses an intermittent feeding device. (Refer to...) Figure 1 and Figure 2 An intermittent feeding device includes a frame 11, with a vertical feeding hopper 1 mounted on the upper side of the frame 11 and a horizontal receiving hopper 2 mounted on the lower side of the feeding hopper 1. The lower end of the feeding hopper 1 is inserted into the receiving hopper 2 and located at one end of the receiving hopper 2. A horizontally oriented, square-section feeding port 21 is opened on the bottom wall of the receiving hopper 2 at the end away from the feeding hopper 1. A conveying hopper 3, perpendicular to the length direction of the receiving hopper 2, is fixedly connected to the lower side of the feeding port 21. The conveying hopper 3 has an open upper side and its bottom wall gradually slopes downward towards the side away from the receiving hopper 2.

[0033] Reference Figure 1 , Figure 2 and Figure 3A vertical vibrating plate 4 is provided inside the receiving hopper 2, at the end furthest from the discharging hopper 1. The lower end of the vibrating plate 4 passes through the discharging port 21 and is located in the conveying hopper 3. The side walls on both sides of the vibrating plate 4 are in contact with the inner side wall of the receiving hopper 2. A horizontal drive shaft 41 is provided and fixedly connected to the upper end of the vibrating plate 4, which is arranged along the width direction of the receiving hopper 2. The ends of the drive shaft 41 pass through the side wall of the receiving hopper 2 and are rotatably connected to the receiving hopper 2. The receiving hopper 2 is provided with a vibrating assembly 5 that drives the vibrating plate 4 to swing along the drive shaft 41, and a feeding assembly 6 that feeds capsules to the discharging port 21 is provided at the end of the receiving hopper 2 near the discharging hopper 1.

[0034] The capsules are fed from the feeding hopper 1 to the receiving hopper 2 at the end away from the feeding port 21. At this time, the feeding component 6 moves the capsules that have entered the receiving hopper 2 toward the feeding port 21, thereby controlling the number of capsules that move to the feeding port 21 at a time and reducing the possibility of a large number of capsules moving to the feeding port 21 and causing blockage. At the same time, the vibration component 5 drives the vibration plate 4 to vibrate back and forth along its own hinge end, so that the cross-sectional area of ​​the channel through which the capsules pass at the feeding port 21 changes continuously, which facilitates feeding and makes it less likely for the capsules to accumulate at the feeding port 21.

[0035] Reference Figure 2 and Figure 3 The vibration assembly 5 includes two torsion springs 51, each corresponding to a drive shaft 41 and sleeved on the corresponding end of the drive shaft 41. The torsion springs 51 are located outside the receiving hopper 2. Limiting blocks 52 are fixedly connected to the ends of the drive shafts 41. The ends of the torsion springs 51 that are far apart from each other are fixedly connected to the corresponding limiting blocks 52, and the other ends are fixedly connected to the outer wall of the receiving hopper 2. When the torsion springs 51 are at their original length, the vibrating plate 4 is vertical. The receiving hopper 2 is provided with a vibrating element 53 that drives the vibrating plate 4 to rotate along the drive shaft 41 towards the discharge hopper 1.

[0036] The vibrating element 53 includes a vibrating block 531 fixedly connected to the vibrating plate 4 on the side away from the hopper 1. The end of the vibrating block 531 away from the hopper 1 passes through the side wall of the receiving hopper 2 and is slidably connected to the receiving hopper 2 along its length. The end of the vibrating block 531 passing through the receiving hopper 2 is configured as an arc shape that gradually protrudes away from the hopper 1. The receiving hopper 2 has a horizontal vibrating rod 532 on the outer side near the end of the vibrating block 531, which is arranged along the width of the receiving hopper 2. The end of the vibrating rod 532 near the vibrating block 531 is bent at a right angle towards the hopper 1. The bent end of the vibrating rod 532 can contact the arc-shaped surface of the vibrating block 531 and drive the vibrating block 531 to move towards the hopper 1.

[0037] A vertical limiting plate 533 is fixedly connected to the outer wall of the receiving hopper 2. The vibrating rod 532 passes through the limiting plate 533 and is slidably connected to the limiting plate 533 along the width direction of the receiving hopper 2. A hinge rod 534 is hinged to the end of the vibrating rod 532 away from itself. A horizontal vibrating disk 535 is provided on the lower side of the end of the hinge rod 534 away from the vibrating rod 532 and is rotatably connected to the outer wall of the receiving hopper 2. The end of the hinge rod 534 away from the vibrating rod 532 is hinged to the upper edge of the vibrating disk 535. A vertical fixed shaft 536 is fixedly connected to the axis on the lower side of the vibrating disk 535. A motor 537 is installed at the lower end of the fixed shaft 536. A mounting platform 538 for fixing the motor 537 is provided on the lower side of the motor 537.

[0038] Motor 537 drives vibratory plate 535 to rotate continuously via fixed shaft 536. When vibratory plate 535 rotates to the point where the hinged end of hinge rod 534 is hinged to vibratory plate 535 and located on the side of vibratory plate 535 away from vibrating block 531, the bent end of vibratory rod 532 is located on the side of vibratory block 531 close to vibratory plate 535. When the hinged end of hinge rod 534 is hinged to vibratory plate 535 and located on the side of vibratory plate 535 close to vibrating block 531, the bent end of vibratory rod 532 is located on the side of vibratory block 531 away from vibratory plate 535. This causes the bent end of vibratory rod 532 to continuously press the arc surface of vibratory block 531 and drive vibratory block 531 to move vibrating plate 4 towards the direction of feeding hopper 1. At this time, torsion spring 51 and vibratory rod 532 cooperate with each other and continuously drive vibrating plate 4 to reset, thereby driving vibrating plate 4 to vibrate back and forth, reducing the possibility of capsules accumulating at feeding port 21.

[0039] Reference Figure 2 and Figure 4 The feeding assembly 6 includes a vertical mounting shaft 61 located at the lower end of the feeding hopper 1 near the feeding port 21. The lower end of the mounting shaft 61 passes through the bottom wall of the receiving hopper 2 and is rotatably connected to the receiving hopper 2. Multiple evenly distributed vertical feeding plates 62 with their lower ends in contact with the bottom wall of the receiving hopper 2 are fixedly connected circumferentially to the upper end of the mounting shaft 61. The side of each feeding plate 62 away from the mounting shaft 61 can contact the inner wall of the receiving hopper 2. A connecting member 63 is provided between the mounting shaft 61 and the fixed shaft 536. The connecting member 63 includes a first gear 631 sleeved and fixedly connected to the fixed shaft 536. A second gear 632 rotatably connected to the bottom wall of the receiving hopper 2 meshes with one side of the first gear 631. A belt 633 connecting the two is installed between the lower side of the second gear 632 and the mounting shaft 61.

[0040] While the motor 537 drives the fixed shaft 536 to rotate the vibratory feeder 535, the belt 633 drives the mounting shaft 61 through the first gear 631 and the second gear 632 to rotate the dial plate 62 with the fixed shaft 536. At this time, the capsule moves to the gap between the adjacent dial plates 62 and moves to the discharge port 21 under the drive of the dial plates 62. Thus, the number of capsules moving to the discharge port 21 at a time is controlled by the gap between the adjacent dial plates 62, reducing the possibility of a large number of capsules moving to the discharge port 21 and causing blockage.

[0041] The implementation principle of the intermittent feeding device in this application embodiment is as follows: the number of capsules moved to the discharge port 21 in a single movement is controlled by the gap between adjacent dial plates 62. At the same time, the vibrating plate 535 and the hinge rod 534 drive the bent end of the vibrating rod 532 to continuously squeeze the arc surface of the vibrating block 531, thereby cooperating with the torsion spring 51 and driving the vibrating plate 4 to vibrate back and forth, reducing the possibility of capsules accumulating at the discharge port 21.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
