[0029] The present invention provides a feeding mechanism 1000 .

[0030] See also Figures 1 to 4 In one embodiment of the present invention, the feeding mechanism includes a conveying platform 1 and a pressing plate assembly 2, the conveying platform 1 is provided with a track 11; the pressing plate assembly 2 includes a base 21, a pressing plate and a driving unit 23, the pressing plate is arranged on the conveying platform 1, the pressing plate is rotatably connected to the base 21, and one end of the pressing plate away from the connection with the base 21 is arranged toward the track, the driving unit 23 is arranged on one side of the conveying platform, the driving end of the driving unit 23 is connected to one end of the pressing plate, and the driving end of the driving unit 23 can drive the pressing plate to rotate relative to the base 21, so that a limiting space for limiting tablets is formed between the pressing plate 21 and the track 11.

[0031] In this embodiment, the feeding mechanism is used to transport materials such as tablets. The conveying platform 1 is used to place materials and the basis for conveying, and the track 11 provides a clear path for the conveying of materials to ensure that the materials move along a predetermined trajectory. The pressure plate assembly 2 is used to achieve the technical effect of flattening the materials during the conveying process. Accordingly, a hole is provided on the first pressure plate 22 and the base, and a rotating shaft is inserted in the middle, and a rotation connection is achieved through the cooperation of the rotating shaft and the hole. The first pressure plate 22 presses down from the edge of materials such as tablets. Furthermore, when the material is transported to the area of ​​the pressure plate assembly 2 on the track 11, the driving end of the driving unit 23 is lifted up and down to drive the connection between the first pressure plate 22 and the driving unit 23 to rotate relative to the base, so that the first pressure plate 22 performs a flattening operation on the track 11.

[0032] The technical solution of the present invention is to set a pressing plate assembly 2 so that when the feeding mechanism is feeding, the material is tilted due to the vibration of the track 11, and the driving end of the driving part 23 in the pressing plate assembly 2 is raised and lowered, so that the pressing plate can be rotated from the end away from the track 11 to the end close to the track 11 to flatten the material, so as to ensure that the material will not be displaced during the transportation of the track 11. The above-mentioned setting method effectively prevents the material from tilting when the track 11 vibrates, improves the stability of material transportation, and improves the overall production efficiency.

[0033] In one embodiment of the present invention, the pressing plate includes a first pressing plate 22, two mounting seats 24 and a second pressing plate 25. Each mounting seat 24 is arranged on the conveying platform 1 and is respectively located on two adjacent sides of the base 21. The first pressing plate 22 is connected to one end of the driving part 23, and the two ends of the second pressing plate 25 are respectively rotatably connected to a mounting seat 24. The first pressing plate 22 rotates relative to the base 21 so that the second pressing plate 25 and the track 11 form a limiting space for limiting tablets.

[0034] In this embodiment, the mounting seat 24 is used to mount the second pressing plate 25, and the second pressing plate 25 is used to flatten the material during the conveying process. Accordingly, in order to increase the flattening area of ​​the material, the second pressing plate 25 is set to flatten the material more effectively. The second pressing plate 25 is located on the lower side of the first pressing plate 22. The first pressing plate 22 is lifted and lowered by the driving end of the driving part 23 so that the connection between the first pressing plate 22 and the base rotates relative to the base. The first pressing plate 22 rotates and presses down, driving the second pressing plate 25 to press down, and the connection between the second pressing plate 25 and the mounting seat 24 rotates relative to the mounting seat 24. It can be understood that when the first pressing plate 22 descends under the action of the driving part 23, it directly applies pressure to the material. Since the connection between the first pressing plate 22 and the base can rotate, this pressure transmission can effectively transmit the downward pressure of the first pressing plate 22 through the rotation mechanism. The downward pressing action of the first pressing plate 22 is transmitted to the second pressing plate 25 through its mechanical connection with the second pressing plate 25, so that the second pressing plate 25 is also pressed down. This linkage effect ensures that the two platens work together to apply even pressure to the material.

[0035] The above arrangement not only improves the flattening effect and efficiency, increases the pressure on the material, and flattens the material more effectively, but also enhances the adaptability and automation level of the equipment by adding the second pressing plate 25 and utilizing the linkage mechanism of the first pressing plate 22. At the same time, it improves the flatness of the material, reduces the local excessive pressure on the material, and thus reduces the risk of damage to the material during the flattening process.

[0036] In an embodiment of the present invention, the pressing plate assembly 2 further includes a first elastic member 26 , and two ends of the first elastic member 26 are respectively connected to the mounting seat 24 and the second pressing plate 25 .

[0037] In this embodiment, in order to avoid damage to the material due to excessive downward pressure, a first elastic member 26 is provided to provide a buffering effect during the material conveying process. Accordingly, the first elastic member 26 is preferably in the form of a spring here. Furthermore, the two ends of the spring are respectively fixed to the surface of the mounting seat 24 and the side surface of the second pressing plate 25 facing the mounting seat 24 by welding. When the second pressing plate 25 is not subjected to the downward pressure of the first pressing plate 22, the spring is in an initial state; when the second pressing plate 25 is subjected to the downward pressure generated by the first pressing plate 22, due to the presence of the spring, the second pressing plate 25 is pressed downward, which can reduce the impact of the second pressing plate 25 on the material, thereby protecting the material. The above-mentioned setting method provides a certain buffer when the second pressing plate 25 applies pressure, reduces the impact on the material, and can also absorb the vibration generated by the pressing plate during the flattening process.

[0038] In one embodiment of the present invention, the loading mechanism also includes a pushing structure 3 and a driving structure 4. A first opening 111 and a second opening 112 are respectively provided on the upper and lower sides of the track 11. Part of the structure of the pushing structure 3 is exposed in the first opening 111, and part of the structure of the driving structure 4 is exposed in the second opening 112.

[0039] In this embodiment, the pusher structure 3 is used to realize the conveying of materials such as tablets, and the drive structure 4 is used to provide a power source for the pusher structure 3. The first opening 111 and the second opening 112 cooperate to push the material forward, ensuring that the material can be effectively pushed and conveyed. The pusher structure 3 contacts the material through the first opening 111, and the drive structure 4 provides the required power through the second opening 112. It can be understood that in order to further avoid damage to the material during the pushing process, the pusher structure 3 is made of rubber. Correspondingly, the pusher structure 3 and the drive structure 4 use the roller 33 to push the material, and the friction between the contact surface between the roller 33 and the material is used to push and convey the material. The roller 33 in the pusher structure 3 and the roller 33 in the drive structure 4 rotate in opposite directions, so that the material is pushed forward. The material of the roller 33 is a wear-resistant material, etc., which is not limited here. The above-mentioned setting method effectively feeds the tablets into the track 11, improving the efficiency and stability of feeding.

[0040] In one embodiment of the present invention, the pushing structure 3 includes a support seat 31, a sliding base 32 and a roller 33. The support seat 31 is arranged on the conveying platform 1. The support seat 31 is provided with a slide rail. The sliding base 32 is slidably connected to the slide rail. The sliding base 32 is provided with a through hole. The roller 33 is clamped in the through hole, and the roller 33 is exposed in the first opening 111.

[0041] In this embodiment, the support seat 31 is used to provide a stable installation foundation to ensure the stability and reliability of the structure during operation; accordingly, the connection between the support seat 31 and the conveying platform 1 can be achieved by means of clamping, plugging, etc. The sliding base 32 is used to achieve sliding movement. Accordingly, a slide rail is provided on the side of the support seat 31 facing the sliding base 32, and the sliding base 32 is slidably connected to the slide rail. Further, a through hole is provided at one end of the sliding base 32 close to the first opening 111, and a rotating shaft is installed in the through hole, and a roller 33 is sleeved on the rotating shaft, and the roller 33 is exposed in the first opening 111. Accordingly, the roller 33 is an elastic pressure wheel here, and the material includes but is not limited to rubber. It can be understood that since the feeding mechanism may push materials of different sizes, in order to adapt to tablets of different thicknesses, the position relationship of the sliding base 32 on the slide rail can be adjusted so that the roller 33 can just contact the material and cooperate with the rotating wheel 42 of the driving structure 4 to push the material forward. The above arrangement can adapt to different sizes and shapes of tablets, provide stable support and positioning, and improve the adaptability of feeding.

[0042] In an embodiment of the present invention, the pushing structure 3 further includes a second elastic member 34 , and the second elastic member 34 is connected to the supporting seat 31 and the sliding base 32 respectively.

[0043] In this embodiment, in order to further ensure the smooth operation of the pusher structure 3 during the conveying process, the support seat 31 is elastically connected to the sliding base 32. Correspondingly, the second elastic member 34 can be connected to the support seat 31 and the sliding base 32 respectively by bonding, bolting, etc. A card slot can be preset on the support seat 31 and the sliding base 32, and the second elastic member 34 is connected to the card slot at both ends to play a role of elastic support and buffering. The second elastic member 34 can also be designed as an embedded structure, directly embedded in the groove or fixing hole in the support seat 31 or the sliding base 32. It is not limited here and can be set according to needs. Preferably, the second elastic member 34 here can be a spring. The above-mentioned setting method can absorb a certain impact force and vibration through the elastic connection between the support seat 31 and the sliding base 32, alleviate external pressure changes, protect the transmission system from damage, and improve durability and service life.

[0044] In one embodiment of the present invention, the roller 33 is made of rubber.

[0045] In this embodiment, the rubber has good elasticity and softness, which can reduce damage to the tablets when abutting against the tablets, and avoid the tablets from being broken or deformed due to hard materials; the rubber roller 33 can absorb part of the vibration and noise when in contact with the tablets, making the entire feeding process smoother and quieter.

[0046] In one embodiment of the present invention, the driving structure 4 includes a bearing 43, a driving motor 41, a synchronous wheel set and a rotating wheel 42. The bearing 43 is located below the track 11. The bearing 43 is provided with a second through hole for the synchronous wheel set and the rotating wheel 42 to be sleeved. The synchronous wheel set includes a first synchronous wheel and a second synchronous wheel sleeved on the synchronous belt. The first synchronous wheel is sleeved on the driving shaft of the driving motor 41. The rotating shaft of the second synchronous wheel is sleeved with the rotating wheel 42, and the rotating wheel 42 is exposed in the second opening 112.

[0047] In this embodiment, the bearing 43 is used to support and fix the rotating wheel 42, the driving motor 41 is used to provide a power source, and the synchronous wheel set ensures that the rotation of the driving motor 41 is precisely synchronized with the rotation of the rotating wheel 42 through the synchronous gear transmission principle. Accordingly, the driving motor 41 drives the first synchronous wheel to rotate through the driving shaft. The first synchronous wheel drives the second synchronous wheel to rotate through the synchronous belt transmission. The second synchronous wheel drives the rotating wheel 42 to rotate through its rotating shaft, thereby realizing motion transmission. The rotating wheel 42 is connected through the rotating shaft of the second synchronous wheel and exposed through the second opening 112, and can directly drive the material to be transported on the track 11. The above-mentioned setting method realizes efficient, stable and reliable power transmission through precise synchronous transmission, bearing 43 support and reasonable structural layout. The driving motor 41 is connected to the synchronous belt through the first synchronous wheel, drives the second synchronous wheel to rotate, thereby driving the rotating wheel 42 to rotate, and the power transmission is more efficient and reduces energy loss. The synchronous wheel set can ensure the precise synchronization between the driving motor 41 and the rotating wheel 42 through the synchronous belt transmission, avoids the error in traditional mechanical transmission, and ensures the consistency of movement.

[0048] In one embodiment of the present invention, the driving structure 4 further includes a sleeve, and the sleeve is sleeved on the synchronous belt.

[0049] In this embodiment, the sleeve is usually a component that matches the tooth shape of the synchronous belt, and its function is to transmit power through the meshing of the gear and the synchronous belt. Correspondingly, the sleeve directly meshes with the synchronous belt through its gear portion. The tooth grooves of the synchronous belt and the gears of the sleeve are perfectly matched, and stable power transmission can be achieved during operation. The above-mentioned setting method can ensure zero slip during the transmission process by matching the tooth shape of the sleeve with the synchronous belt, ensuring efficient and stable power transmission. The meshing of the gears of the sleeve on the synchronous belt ensures the accurate transmission of power, avoids transmission errors or slippage, and thus improves the transmission efficiency of the system. At the same time, the transmission accuracy is also improved.

[0050] In one embodiment of the present invention, the feeding mechanism also includes two pushing structures 3, the driving structure 4 includes a driving motor 41, a first synchronous wheel, a second synchronous wheel and a third synchronous wheel, the driving shaft of the driving motor 41 is sleeved with the first synchronous wheel, the first synchronous wheel is respectively sleeved with the second synchronous wheel and the third synchronous wheel through a synchronous belt, the second synchronous wheel cooperates with one of the pushing structures 3, and the third synchronous wheel cooperates with the other pushing structure 3.

[0051] In this embodiment, in order to further realize efficient power transmission, two pusher structures 3 are set to realize power transmission through a driving structure 4. The first synchronous wheel serves as the output end of the driving motor 41, and transmits power to the second and third synchronous wheels through a synchronous belt. The second synchronous wheel transmits power to one pusher structure 3 through a synchronous belt, thereby driving the pusher movement. The third synchronous wheel transmits power to another pusher structure 3 through a synchronous belt, driving the other pusher mechanism to move. This multi-wheel and multi-belt configuration can ensure the simultaneous driving of the two pusher structures 3, thereby ensuring the synchronization and stability during the feeding process to a certain extent. Further, when the driving motor 41 is started, the motor transmits power through the synchronous wheel set and the synchronous belt, driving the pusher structure 3 to push the material in a predetermined direction. The above-mentioned setting method reduces energy loss and improves the working efficiency of the system through the efficient cooperation of the synchronous belt and the synchronous wheel. At the same time, since the synchronous belt transmission does not produce slip, the movement accuracy of the two pusher structures 3 is ensured, and the problem of unbalanced or misaligned pushing caused by asynchronous power transmission is avoided.

[0052] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
