[0001] The utility model belongs to the field of medicine bottle processing equipment, and particularly relates to a medicine bottle printing device. Background Art

[0002] During the production process of medicine bottles such as ampoules, it is often necessary to print batch numbers, production dates and other information on the bottle body. After the bottle body is printed, a UV lamp is required to irradiate it to accelerate the curing of the printing ink. Since the bottle body is circular, the UV lamp can only irradiate a partial area of the bottle body, resulting in an unsatisfactory curing effect and affecting the printing quality. Content of the Utility Model

[0003] In order to solve the deficiencies of the prior art, the utility model aims to provide a medicine bottle printing device, which can rotate the printed medicine bottle, and then can cure the printing area of the bottle body in all directions, thus significantly improving the printing quality of the medicine bottle.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A medicine bottle printing device includes a machine shell and a printing mechanism. The machine shell is arranged above a chain conveyor, and the medicine bottles are placed flat between the chains above the chain conveyor; along the feeding direction of the chain conveyor, a printing mechanism and a plurality of curing lamps are installed below the machine shell. A bottle rubbing mechanism is also arranged between adjacent curing lamps, and the bottle rubbing mechanism is in sliding contact with the upper surface of the medicine bottle to rotate it by a certain angle.

[0006] Preferably, the bottle rubbing mechanism includes a bottle rubbing roller horizontally installed between two adjacent curing lamps.

[0007] Preferably, a resistance increasing layer is arranged on the bottle rubbing roller; the lower part of the bottle rubbing roller is designed as a non-concentric arc shape.

[0008] Preferably, the bottle rubbing roller is arranged to move up and down, and the bottle rubbing roller is connected with an elastic limiting component.

[0009] Preferably, the elastic limiting component includes a connecting rod, a rotating shaft, an elastic pressing component and a swing arm component. One end of the connecting rod is vertically fixed to the end of the bottle rubbing roller, and the other end of the connecting rod is vertically fixed to one end of the rotating shaft. The rotating shaft is horizontally rotatably installed on the machine shell; the swing arm component includes a first linkage arm and a second linkage arm, and both the first linkage arm and the second linkage arm are vertically fixed to the other end of the rotating shaft; a lower limiting part is arranged on the machine shell, and the lower limiting part limits the swing angle of the second linkage arm; the elastic pressing component vertically presses on the first linkage arm.

[0010] Preferably, the lower limiting part includes a limiting block and an adjusting screw. The limiting block is fixed on the machine shell, the upper end of the adjusting screw threadedly penetrates through the limiting block and abuts against the lower part of the second linkage arm, and the lower end is provided with a first adjusting part.

[0011] Preferably, the elastic crimping member includes a connecting block, a spring and a pressing rod. The connecting block is installed on the casing. A sliding hole is vertically formed at the bottom of the connecting block. The pressing rod is vertically slidably arranged in the sliding hole and abuts against the spring in the sliding hole. The lower end of the pressing rod is crimped on the first linkage arm.

[0012] Preferably, a lead screw is vertically installed on the casing. The connecting block is threadedly sleeved on the lead screw, and a second adjusting portion is provided at the end of the lead screw.

[0013] Preferably, a light-shielding plate is fixedly provided on the casing between the printing mechanism and the adjacent curing lamp.

[0014] Preferably, a plurality of rotating rings are coaxially installed on the chain of the chain conveyor, and the medicine bottles are horizontally supported on the rotating rings.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. When the chain conveyor carries the medicine bottles forward and contacts the bottle rubbing mechanism, the bottle rubbing mechanism will rub the upper surface of the medicine bottles to rotate. The rotatably arranged rotating rings can effectively reduce the friction between the medicine bottles and the chain, so that the rotation of the medicine bottles is smoother.

[0017] 2. The bottle rubbing mechanism includes a bottle rubbing roller horizontally installed between two adjacent curing lamps. The lower half of the bottle rubbing roller is designed as a non-concentric arc shape, which can increase the contact area between the bottle rubbing roller and the medicine bottles.

[0019] 4. A lower limit member is provided on the casing. The lower limit member limits the swinging angle of the second linkage arm, and effectively limits the descending height of the bottle rubbing roller through the linkage cooperation of the rotating shaft and the connecting rod. By changing the elongation length of the adjusting screw above the limit block, the maximum downward swinging angle of the second linkage arm can be adjusted, so as to adjust the lowest descending height of the bottle rubbing roller, and thus it can be adapted to the bottle rubbing rotation of medicine bottles with different diameter models.

[0020] 5. By rotating the lead screw to drive the connecting block to move up and down, the magnitude of the elastic force exerted by the spring in the sliding hole on the pressing rod can be adjusted. Furthermore, through the cooperation of the first linkage arm, the rotating shaft and the connecting rod, the force exerted by the bottle rubbing roller downward on the medicine bottles can be adjusted, which is more convenient for installation and debugging during the bottle rubbing operation of medicine bottles with different diameter models.

[0021] 6. Since the bottom of the bottle rubbing roller is lower than the top of the medicine bottles on the chain conveyor, when the medicine bottles are conveyed to the bottle rubbing roller, the bottle rubbing roller will be pushed upward, the connecting rod will swing, and the rotating shaft will rotate, causing the first linkage arm to swing upward to lift the pressing rod and compress the spring. Under the elastic force of the spring, the bottle rubbing roller can be closely abutted against the medicine bottles, avoiding slipping and improving the quality of bottle rubbing rotation.

[0022] 7. A light-shielding plate is fixedly installed on the machine shell between the printing mechanism and its adjacent curing lamp, which can prevent the curing lamp from affecting the printing mechanism in front. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and do not limit the scope of use of the present utility model.

[0029] As Figures 1-5 shown, the present utility model provides a medicine bottle printing device, which includes a machine shell 2 and a printing mechanism 3. The machine shell 2 is provided above the chain conveyor 1. The medicine bottles are placed flat between the chains above the chain conveyor 1 and are conveyed forward as the chain conveyor 1 moves forward. Two rotating rings are coaxially installed on the chains of the chain conveyor 1, and the medicine bottles are horizontally supported on the rotating rings. Specifically, in implementation, the rotating rings can adopt a bearing structure. When the chain conveyor 1 carries the medicine bottles forward and contacts the bottle rubbing mechanism, the bottle rubbing mechanism will rub the upper surface of the medicine bottles to rotate, and the rotatably arranged rotating rings can effectively reduce the friction between the medicine bottles and the chains, thereby making the rotation of the medicine bottles smoother.

[0030] Along the feeding direction of the chain conveyor 1, a printing mechanism 3, two bottle rubbing mechanisms and three curing lamps 4 (UV lamps) are installed under the casing 2. The bottle rubbing mechanisms are installed between adjacent curing lamps 4. The bottle rubbing mechanism is in sliding contact with the upper surface of the medicine bottle to rotate it by a certain angle. Specifically, the bottle rubbing mechanism includes a bottle rubbing roller 5 horizontally installed between two adjacent curing lamps 4. The lower half of the bottle rubbing roller 5 is designed with non-concentric arcs, which can increase the contact area between the bottle rubbing roller 5 and the medicine bottle. The bottle rubbing roller 5 is provided with a resistance-increasing layer, and the resistance-increasing layer can be an O-ring 50 made of silica gel sleeved on the bottle rubbing roller 5, which can effectively increase the friction between the bottle rubbing roller 5 and the medicine bottle, improve the stability during bottle rubbing, and prevent slipping during bottle rubbing.

[0031] The bottle rubbing roller 5 is arranged to move up and down, and the bottle rubbing roller 5 is connected to an elastic limiting component. Among them, the elastic limiting component includes a connecting rod 51, a rotating shaft 52, an elastic pressing member 6 and a swing arm assembly 53. One end of the connecting rod 51 is vertically and fixedly connected to the end of the bottle rubbing roller 5, and the other end of the connecting rod 51 is vertically and fixedly connected to one end of the rotating shaft 52. The rotating shaft 52 is horizontally rotatably installed on the casing 2; the swing arm assembly 53 includes a first linkage arm 531 and a second linkage arm 532, and both the first linkage arm 531 and the second linkage arm 532 are vertically and fixedly connected to the other end of the rotating shaft 52; a lower limiting member is provided on the casing 2, and the lower limiting member limits the swinging angle of the second linkage arm 532, and effectively limits the descending height of the bottle rubbing roller 5 through the linkage cooperation of the rotating shaft 52 and the connecting rod 51.

[0032] Among them, the lower limiting member includes a limiting block 22 and an adjusting screw 221. The limiting block 22 is fixedly arranged on the casing 2. The upper end of the adjusting screw 221 threadedly penetrates through the limiting block 22 and abuts against the lower part of the second linkage arm 532, and the lower end is provided with a first adjusting part. The combination of the first adjusting part and the adjusting screw 221 can adopt a bolt structure. By changing the extension length of the adjusting screw 221 above the limiting block 22, the maximum downward swinging angle of the second linkage arm 532 can be adjusted, so as to adjust the lowest descending height of the bottle rubbing roller 5, and thus it can be adapted to the bottle rubbing and rotation of medicine bottles of different diameter models.

[0033] The elastic crimping member 6 is vertically crimped on the first linkage arm 531. Among them, the elastic crimping member 6 includes a connecting block 61, a spring 64 and a pressing rod 63. A sliding hole 610 is vertically formed at the bottom of the connecting block 61. The pressing rod 63 is vertically slidably arranged in the sliding hole 610 and abuts against the spring 64 in the sliding hole 610. The lower end of the pressing rod 63 outside the sliding hole 610 is crimped on the first linkage arm 531. In addition, a lead screw 62 is vertically installed on the machine shell 2. The connecting block 61 is threadedly sleeved on the lead screw 62. A second adjusting portion 621 is provided at the end of the lead screw 62. The second adjusting portion 621 can adopt the adjusting form of an internal hexagonal hole. By rotating the lead screw 62 to drive the connecting block 61 to move up and down, the elastic force applied by the spring 64 in the sliding hole 610 to the pressing rod 63 can be adjusted. Furthermore, through the cooperation of the first linkage arm 531, the rotating shaft 52 and the connecting rod 51, the force applied by the bottle rubbing roller 5 downward on the medicine bottle can be adjusted, which is more convenient for the installation and debugging during the bottle rubbing operation of medicine bottles with different diameter models.

[0034] Since the bottom of the bottle rubbing roller 5 is lower than the top of the medicine bottle on the chain conveyor 1, when the medicine bottle is conveyed to the bottle rubbing roller 5, it will push the bottle rubbing roller 5 upward. The connecting rod 51 swings, the rotating shaft 52 rotates, so that the first linkage arm 531 swings upward to push up the pressing rod 63 and compress the spring 64. Under the elastic force of the spring 64, the bottle rubbing roller 5 can be tightly abutted against the medicine bottle to avoid slipping and improve the quality of bottle rubbing and rotation.

[0035] A light-shielding plate 21 is fixedly provided on the machine shell 2 between the printing mechanism 3 and the adjacent curing lamp 4 to prevent the curing lamp 4 from affecting the printing mechanism 3 in front.

[0036] When using the present utility model, the medicine bottle is horizontally placed on the chain conveyor 1 and steadily conveyed forward. After being spray-printed by the printing mechanism 3, the first curing lamp 4 first irradiates and cures the printing area at the top of the medicine bottle. As the medicine bottle continues to be conveyed forward, the first bottle rubbing roller 5 slides against the upper part of the medicine bottle and rubs it to rotate a certain angle, so that the adjacent uncured printing area is directly above. Then, the second curing lamp 4 irradiates and cures it; then the second bottle rubbing roller 5 rubs the medicine bottle to rotate, and the subsequent curing lamps 4 irradiate and cure the remaining printing areas, so as to realize the all-round irradiation and curing of the printing area of the medicine bottle, and significantly improve the printing quality of the medicine bottle.
