Description

Technical Field

[0001] This utility model is a locking device for capsule filling, belonging to the field of capsule filling. Background Technology

[0002] Capsule filling mainly refers to the process of filling a specific substance into an empty capsule shell. This is common in the preparation of pharmaceuticals, health products, and certain special foods. Capsule filling locking equipment is a device used to precisely close the capsule cap and capsule body after the capsule is filled. Its core function is to ensure the sealing and stability of the capsule.

[0003] Existing capsule filling locking equipment mainly involves placing a half-shell capsule filled with material into the lower medicine plate capsule slot. The half-shell capsule to be locked engages with the upper medicine plate capsule slot. The upper medicine plate moves downward to press down on the lower medicine plate, locking the upper and lower half-shell capsules together. However, to make the capsule locking more secure, the medicine plate applies a large pressure to the top half-shell capsule when pressing downward. Since the end of the capsule shell is curved, the curved surface of the top half-capsule shell is easily deformed. The deformed capsule shell cannot automatically recover, resulting in the finished capsules failing to meet the qualification requirements and reducing the capsule production qualification rate. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a locking device for capsule filling to solve the problems mentioned in the background art. This utility model ensures that the capsules after locking by the device will not have a dented shell, thereby improving the capsule production qualification rate.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a locking device for capsule filling, including a worktable, a bottom capsule support component is provided on the top of the worktable, a frame is fixedly connected to the top of the worktable, a cylinder is fixedly connected to the inner top wall of the frame, and a locking component is provided at the bottom of the cylinder.

[0006] The locking component includes a support frame, a support groove is provided on one side of the support frame, a top medicine plate is slidably connected to the inner wall of the support groove, a top capsule support component is provided on the top of the top medicine plate, a spring is fixedly connected to the top of the support frame, a pressure plate is fixedly connected to the top of the spring, the top of the pressure plate is fixedly connected to the bottom of the cylinder, and a pressing component is provided at the bottom of the pressure plate.

[0007] Furthermore, a second magnetic block is provided at the bottom of the top medicine plate, and a first magnetic block is provided on the inner wall of the support groove. The first magnetic block and the second magnetic block attract each other.

[0008] Furthermore, a slide rail is provided at the top of the support frame, and a slide rod is fixedly connected to the bottom of the pressure plate. The outer wall of the slide rod is slidably connected to the inner wall of the slide rail.

[0009] Furthermore, the bottom capsule support component includes a support base fixedly connected to the top of the workbench. The top of the support base has a support groove, the inner bottom wall of the support groove is provided with a vacuum suction cup, the inner wall of the support groove is movably engaged with a bottom medicine plate, the top of the bottom medicine plate has a bottom capsule groove, and the outer wall of the bottom medicine plate is fixedly connected with a handle.

[0010] Furthermore, the top capsule support component includes a capsule channel, which is formed on the top of the top medicine plate, and the inner wall of the capsule channel is provided with protruding particles.

[0011] Furthermore, the pressing component includes a pressing rod fixedly connected to the bottom of the pressing plate. The bottom of the pressing rod has a pressing groove, and a silicone pad is fixedly connected to the inner wall of the pressing groove. An adsorption groove is formed on the inner wall of the silicone pad, and the pressing rod is slidably sleeved with the support frame.

[0012] Furthermore, the groove is an arc-shaped structure, and the shape of the silicone pad is the same as the shape of the groove.

[0013] The beneficial effects of this utility model are: 1. Because the shape of the pressure groove is compatible with the top of the top half-shell capsule, it can fit the top of the top half-shell capsule more closely. When the pressure rod applies pressure to the top half-shell capsule, the top half-shell capsule is subjected to more uniform force, reducing the probability of deformation. When the silicone pad presses the top half-shell capsule, the air inside the adsorption groove is discharged. Through the action of air pressure, an adsorption force is exerted on the top half-shell capsule. When the pressure rod returns to its original position and the silicone pad is separated from the top half-shell capsule, the top half-shell capsule has an upward adsorption force. If there is any deformation in the top half-shell capsule, it can also be reset and restored. This ensures that the capsule after locking by the device will not have a dented outer shell, thus improving the capsule production qualification rate.

[0014] 2. After the top half-shell capsule and the bottom half-shell capsule are locked together, the vacuum suction cup can adsorb the capsule, so that the locked capsule is located inside the bottom capsule groove. The operation of the cylinder drives the support frame to move downward until it contacts the support base. Then, the bottom of the top half-shell capsule extends into the bottom capsule groove, which further meets the working requirements of the device and improves the practicality of the device.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-8 This utility model provides a technical solution: a locking device for capsule filling, including a workbench 1, a bottom capsule support component is provided on the top of the workbench 1, a frame 5 is fixedly connected to the top of the workbench 1, a cylinder 6 is fixedly connected to the inner top wall of the frame 5, and a locking component is provided at the bottom of the cylinder 6.

[0019] The locking component includes a support frame 7, a support groove 701 is provided on one side of the support frame 7, a top medicine plate 8 is slidably connected to the inner wall of the support groove 701, a top capsule support component is provided on the top of the top medicine plate 8, a spring 704 is fixedly connected to the top of the support frame 7, a pressure plate 705 is fixedly connected to the top of the spring 704, the top of the pressure plate 705 is fixedly connected to the bottom of the cylinder 6, and a pressing component is provided at the bottom of the pressure plate 705.

[0020] Furthermore, a second magnetic block 803 is provided at the bottom of the top medicine plate 8, and a first magnetic block 702 is provided on the inner wall of the support groove 701. The first magnetic block 702 and the second magnetic block 803 attract each other. The mutual attraction between the first magnetic block 702 and the second magnetic block 803 can limit the top medicine plate 8, and the top medicine plate 8 will not automatically detach from the support groove 701.

[0021] Furthermore, a slide rail 703 is provided on the top of the support frame 7, and a slide rod 706 is fixedly connected to the bottom of the pressure plate 705. The outer wall of the slide rod 706 is slidably connected to the inner wall of the slide rail 703. The slide rod 706 can play a limiting role. When the pressure plate 705 moves towards the support frame 7, its movement trajectory is a vertical trajectory and there will be no skew.

[0022] Please see Figures 1-2 The bottom capsule support component includes a support base 2 fixedly connected to the top of the workbench 1. The top of the support base 2 has a support groove 3. The inner bottom wall of the support groove 3 is provided with a vacuum suction cup. The vacuum suction cup is an existing device, model ZP10CS. The vacuum suction cup is connected to an external vacuum system device. When the vacuum suction cup is activated, it will exert an adsorption force on the upper part of the device. The inner wall of the support groove 3 is movably engaged with a bottom medicine plate 4. The top of the bottom medicine plate 4 has a bottom capsule groove 401. The outer wall of the bottom medicine plate 4 is fixedly connected with a handle 402. The half-capsule shell containing the material at the bottom is located inside the bottom capsule groove 401. The bottom capsule groove 401 is a through groove, and the inner bottom wall of the bottom capsule groove 401 has air holes. After the top half-shell capsule and the bottom half-shell capsule are locked together, the vacuum suction cup can adsorb the capsule, thereby making the locked capsule located inside the bottom capsule groove 401.

[0023] Please see Figures 1-7 The top capsule support component includes a capsule channel 801, which is located on the top of the top medicine plate 8. The inner wall of the capsule channel 801 is provided with protruding particles 802, which can limit the top half-shell capsule. The top half-shell capsule will not automatically detach from the capsule channel 801 without external pressure.

[0024] Please see Figures 1-8The pressing component includes a pressing rod 7051 fixedly connected to the bottom of the pressing plate 705. The bottom of the pressing rod 7051 has a pressing groove 7052. A silicone pad 7053 is fixedly connected to the inner wall of the pressing groove 7052. An adsorption groove 7054 is formed on the inner wall of the silicone pad 7053. The pressing rod 7051 is slidably sleeved with the support frame 7. After the operation of the cylinder 6 drives the support frame 7 to move downward and contact the support seat 2, the bottom of the top half-shell capsule extends into the interior of the bottom capsule groove 401. Then, the pressing plate 705 continues to move under the force of the cylinder 6, which in turn drives the pressing rod 7051 to move downward. The pressing rod 7051 presses the top half-shell capsule through the pressing groove 7052, and the top half-shell capsule is pressed out of the capsule through groove 801, thereby locking the top half-shell capsule and the bottom half-shell capsule together.

[0025] Specifically, the pressure groove 7052 has an arc-shaped structure, and the shape of the silicone pad 7053 is the same as that of the pressure groove 7052. The shape of the pressure groove 7052 is adapted to the top of the top half-shell capsule, thus allowing it to fit the top of the top half-shell capsule more closely. When pressure is applied to the top half-shell capsule, the top half-shell capsule is subjected to more even force, reducing the probability of deformation. In addition, the silicone pad 7053 is made of soft material and can play a protective role. When the silicone pad 7053 presses the top half-shell capsule, the air inside the adsorption groove 7054 is discharged. Through the action of air pressure, an adsorption force is exerted on the top half-shell capsule. When the pressure rod 7051 resets and the silicone pad 7053 is separated from the top half-shell capsule, the top half-shell capsule has an upward adsorption force. If there is any deformation in the top half-shell capsule, it can also be reset and restored.

[0026] Working principle: The half-capsule shell containing the material at the bottom is located inside the bottom capsule groove 401. Then, the pressure plate 705 continues to move under the force of the cylinder 6, which in turn drives the pressure rod 7051 to move downward. The pressure rod 7051 presses the top half-capsule shell through the pressure groove 7052, thus pressing the top half-capsule shell out of the capsule through groove 801, thereby locking the top half-capsule shell and the bottom half-capsule shell together. After the top half-capsule shell and the bottom half-capsule shell are locked together, the vacuum suction cup can adsorb the capsule, so that the locked capsule is located inside the bottom capsule groove 401. The operation of the cylinder 6 drives the support frame 7 to move downward until it contacts the support base 2, and the bottom of the top half-capsule shell extends into the bottom capsule groove 401.

[0027] Because the shape of the pressure groove 7052 is adapted to the top of the top half-shell capsule, it can fit the top of the top half-shell capsule more closely. When the pressure rod 7051 applies pressure to the top half-shell capsule, the top half-shell capsule is subjected to more uniform force, reducing the probability of deformation. When the silicone pad 7053 presses the top half-shell capsule, the air inside the adsorption groove 7054 is discharged. Through the action of air pressure, an adsorption force is exerted on the top half-shell capsule. When the pressure rod 7051 resets and the silicone pad 7053 is separated from the top half-shell capsule, the top half-shell capsule has an upward adsorption force. If there is any deformed part of the top half-shell capsule, it can also be reset and restored.
