[0027] The positioning assembly comprises two clamping plates 301 sleeved on the base 1 in a mouth shape, the bottom of the base 1 is provided with a bidirectional threaded rod 302, the two clamping plates 301 are in threaded cooperation with the bidirectional threaded rod 302, one end of the bidirectional threaded rod 302 is fixedly installed with a rotating block 5, the other end of the bidirectional threaded rod 302 is rotatably installed with a mounting block 6, and the top of the mounting block 6 is fixedly installed with the bottom of the base 1.

[0028] When the bidirectional threaded rod 302 is rotated, the two clamping plates 301 are moved relative to or away from each other due to the threaded cooperation of the two clamping plates 301 with the bidirectional threaded rod 302 and the opposite threaded directions, so that the bottles can be preliminarily positioned according to the diameter of the plastic medicine bottles, and the capping requirements of different sizes of bottles are met.

[0029] The opposite ends of the two clamping plates 301 are provided with first sliding grooves 7, the inside of each first sliding groove 7 is fixedly installed with a limiting rod 8, each limiting rod 8 is sleeved with a first sliding block 9, one end of each first sliding block 9 is rotatably installed with a connecting plate 10, one end of each two adjacent connecting plates 10 is hingedly connected, the hinged portions of each two adjacent connecting plates 10 are rotatably installed with fixed plates 11, arc-shaped plates 12 are fixedly installed between each two adjacent fixed plates 11, springs 13 are sleeved on each limiting rod 8, and the two ends of each spring 13 are in abutment with the adjacent first sliding block 9 and the inner wall of the first sliding groove 7.

[0030] When the clamping plates 301 are moved relative to each other, the first sliding blocks 9 slide on the limiting rods 8, the connecting plates 10 are driven to rotate, the springs 13 always push the first sliding blocks 9 to move, the connecting plates 10 push the arc-shaped plates 12 to move, the arc-shaped plates 12 push the two sides of the bottles to more closely adhere to the surface of the bottles, the precise positioning of the bottles is realized, the elastic force of the springs 13 makes the arc-shaped plates 12 always maintain a certain pressure on the bottles, the bottles are further stabilized during the positioning process, the bottles are prevented from shaking before capping, and the clamping force on the bottles can be buffered to a certain extent, so that the bottles are prevented from being damaged by clamping.

[0031] Second sliding grooves 14 are formed in the top of the base 1, second sliding blocks 15 are slidably arranged in the second sliding grooves 14, and the top of each second sliding block 15 is fixedly installed with the bottom of the adjacent arc-shaped plate 12.

[0032] The second sliding blocks 15 slide in the second sliding grooves 14, so that the arc-shaped plates 12 are more stable during movement, and the precision of the positioning of the bottles is further improved.

[0033] The fixing assembly comprises a ratchet wheel 401 fixedly sleeved on the rotating block 5, and one side of the base 1 is provided with a limiting block 402 internally provided with a torsion spring, and a clamping block 403 for clamping the ratchet wheel 401 is fixedly installed on the cylindrical surface of the limiting block 402.

[0034] When the position of the clamping plate 301 is adjusted by rotating the rotating block 5, the clamping block 403 is clamped into the tooth groove of the ratchet wheel 401 under the action of the torsion spring, the rotation of the ratchet wheel 401 is limited, the accidental rotation of the bidirectional threaded rod 302 is prevented, the fixing effect of the positioning assembly on the medicine bottle is ensured, and the displacement of the medicine bottle in the capping process is avoided.

[0035] The implementation principle of the capping machine for plastic medicine bottles in the embodiment of the application is as follows: first, the medicine bottle to be capped is placed on the base 1, and at this time, the equipment is in an initial state.

[0036] When the operator rotates the rotating block 5, the rotating block 5 drives the bidirectional threaded rod 302 fixedly connected thereto to rotate, since the bidirectional threaded rod 302 is threadedly connected with the two clamping plates 301, and the rotation directions of the two threads on the bidirectional threaded rod 302 are opposite, when the bidirectional threaded rod 302 rotates, the two clamping plates 301 move relatively along the bidirectional threaded rod 302, and gradually approach each other.

[0037] In the process that the two clamping plates 301 gradually approach each other, the first sliding blocks 9 on the two clamping plates 301 also approach each other, so that the adjacent connecting plates 10 are pushed to approach each other, and the connecting plates 10 approach each other. In this process, the spring 13 sleeved on each limiting rod 8 plays an important role. The two ends of the spring 13 are respectively in abutment with the adjacent first sliding block 9 and the inner wall of the first sliding groove 7. The spring 13 is always in a compressed or stretched state and generates a spring force. The spring force pushes the first sliding block 9, and further pushes the connecting plate 10 connected thereto, so that the connecting plate 10 drives the fixed plate 11 and the arc-shaped plate 12 fixed between the fixed plates 11 to move towards the medicine bottle.

[0038] In the moving process of the arc-shaped plate 12, the arc-shaped plate 12 gradually approaches the medicine bottle and is in contact with the surface of the medicine bottle. Since the arc-shaped plate 12 is designed in the shape, it can well fit the outer wall of the medicine bottle. Under the continuous spring force of the spring 13, the arc-shaped plate 12 continuously pushes the medicine bottle, until the medicine bottle is adjusted to the center position of capping, and precise positioning is realized.

[0039] Meanwhile, the second sliding block 15 in the second sliding groove 14 on the top of the base 1 is fixedly installed at the top of the adjacent arc-shaped plate 12. When the arc-shaped plate 12 moves, the second sliding block 15 slides in the second sliding groove 14. This structure ensures the stability of the arc-shaped plate 12 in the moving process, prevents the arc-shaped plate 12 from shaking or deviating, and further ensures the accuracy of the positioning of the medicine bottle.

[0040] When the medicine bottle is accurately positioned, the fixing assembly works, the ratchet 401 fixed on the rotating block 5 rotates with the rotating block 5, when the medicine bottle is positioned and the rotating block 5 stops rotating, the limiting block 402 installed on one side of the base 1 and internally provided with a torsion spring, the clamping block 403 fixed on the cylindrical surface of the limiting block 402, will be automatically clamped into the tooth groove of the ratchet 401 under the action of the torsion spring, so that the rotation of the ratchet 401 is limited, and in turn the rotation of the bidirectional threaded rod 302 is prevented, so that the positioning state of the medicine bottle by the positioning assembly is fixed, and it is ensured that the medicine bottle will not be displaced in the subsequent capping process.

[0041] At this time, the capping assembly 2 is started, the capping assembly 2 starts to work, and the medicine bottle located at the center position and stably positioned is subjected to capping operation, the capping assembly 2 accurately presses the bottle cap on the bottle opening through a specific mechanical structure and a power device, the whole capping process is completed, and in the whole operation process, the components are matched with each other, the positioning and capping of the medicine bottle are accurately realized, and the quality and efficiency of capping are effectively improved.

[0042] The above-mentioned embodiments are only preferred embodiments of the utility model, and cannot be used to limit the range of protection of the utility model, and any non-substantial change and replacement made by the person skilled in the art on the basis of the utility model belongs to the range of protection required by the utility model.
