Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Components of the embodiments of the present utility model usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.
[0034] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.
[0035] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0036] During the production process of pharmaceutical glass tubes, mechanical grinding wheels and water are generally used for cutting. During cutting, the glass tube needs to be heated first, and then water is dropped on the grinding wheel to perform cutting using the temperature difference and the grinding wheel. This cutting method will generate a large amount of glass debris, which not only pollutes the product but also may bring potential pollution risks to the subsequent medicine filling process. At the same time, when the grinding wheel wrapped with water is cutting, the water will splash on the glass tube to produce watermarks, affecting the appearance quality of the product.
[0037] In view of this, the present utility model provides a flame cutting device for the production of pharmaceutical glass tubes, including a burner 100, a conveying component 200, a rotating component 300, a separating component 400, and a gas nozzle 500; the burner 100 is used to heat the cutting position of the glass tube; the conveying component 200 is used to drive the glass tube to move; the rotating component 300 includes a belt 310, and the belt 310 contacts the glass tube to drive the glass tube to rotate around its own axis; the separating component 400 includes a clamp 410, and the clamp 410 clamps the cut-off section of the glass tube and can move axially along the glass tube to break the glass tube from the cutting position; the gas nozzle 500 is used to blow air at the cut glass tube to blow through the heat-sealed glass tube.
[0038] The flame cutting device for the production of medicinal glass tubes provided by the present utility model drives the glass tube to move forward and rotate around its own axis through the cooperation of the conveying component 200 and the rotating component 300, so that the cutting position of the glass tube is uniformly heated to the softening point temperature by the burner 100, facilitating the clamping of the glass tube by the clamping jaw 410 to be cut off and pulling off the cut-off section and the reserved section from the cutting position. This cutting method avoids the problems of chip pollution and water marks in the mechanical grinding wheel cutting method, has the advantages of high cutting quality and high production efficiency, and is suitable for the large-scale production of medicinal glass tubes.
[0039] The following Figures 1 - 5 will describe in detail the structure and shape of the flame cutting device for the production of medicinal glass tubes provided in this embodiment:
[0040] In this embodiment, the burner 100 extends along the conveying direction of the glass tube to ensure uniform heating of the glass tube during its movement, as Figure 1 , Figure 2 shown, so that the glass tube is easily pulled off from the heated place and chips are avoided.
[0041] In this embodiment, the conveying component 200 includes a conveying chain 210, a limiting block 220, a driving sprocket 230 and a driven sprocket 240, as Figure 3 shown. The driving sprocket 230 and the driven sprocket 240 are connected by the conveying chain 210 to form a chain drive structure; a plurality of limiting blocks 220 are arranged along the length direction of the chain, and the glass tube is arranged between two adjacent limiting blocks 220 to ensure that the glass tubes do not affect each other and ensure that the belt 310 can drive the glass tube to rotate around its own axis.
[0042] In this embodiment, the rotating component 300 includes a belt 310, a driving pulley 320 and a driven pulley 330, as Figure 4 shown. The driving pulley 320 and the driven pulley 330 are connected by the belt 310 to form a belt drive structure. The driving pulley 320 is driven by a motor to accurately control the rotation speed of the glass tube and ensure its uniform heating.
[0043] In this embodiment, the moving direction of the belt 310 is the same as or opposite to the direction in which the conveying component 200 drives the glass tube. When the moving direction of the belt 310 is the same as the direction in which the conveying component 200 drives the glass tube, their speeds should be kept unequal to drive the glass tube to rotate around its own axis by the friction force of the belt 310 on the glass tube. Preferably, the moving direction of the belt 310 is opposite to the direction in which the conveying component 200 drives the glass tube, so that the glass tube can obtain a faster rotation speed with the minimum energy consumption. That is, the driving sprocket 230 rotates counterclockwise and the driving pulley 320 rotates clockwise. In addition, the belt 310 can also remain stationary.
[0044] In this embodiment, the flame cutting device for the production of medicinal glass tubes includes two conveying components 200 and two rotating components 300, as Figure 1 shown. The rotating component 300 and the conveying component 200 are both arranged along the length direction of the glass tube, and the two rotating components 300 are arranged between the two conveying components 200. That is, a stable support for both ends of the glass tube is formed to ensure the smoothness of the conveying process and the cutting process.
[0045] In this embodiment, the separating component 400 includes a clamping jaw 410, a telescopic rod 420, a linear movement module 430, and a bracket 470, as Figure 5 shown. Among them, the clamping jaw 410 is set as a pneumatic clamping jaw for grasping the cut-off section of the glass tube; the telescopic rod 420 is connected to the clamping jaw 410 and installed on the linear movement module 430 for driving the clamping jaw 410 to move in the vertical direction; the linear movement module 430 is installed on the bracket 470 for driving the telescopic rod 420 to move in the horizontal direction; the bracket 470 is fixed to the ground.
[0046] During cutting, the linear movement module 430 drives the telescopic rod 420 and the clamping jaw 410 to move to the cutting station. Subsequently, the telescopic rod 420 extends downward to drive the clamping jaw 410 to move, and then the clamping jaw 410 clamps the cut-off section of the glass tube. After clamping, the linear movement module 430 drives the telescopic rod 420 and the clamping jaw 410 to move along the axial direction of the glass tube, so as to break the cut-off section of the glass tube from the remaining section. Then the clamping jaw 410 releases to release the cut-off section.
[0047] In this embodiment, to control the stroke of the telescopic rod 420 and the linear movement module 430, the separating component 400 further includes a cutting limit switch 440, a reset limit switch 450, and a magnetic induction switch 460. Specifically, the cutting limit switch 440 and the reset limit switch 450 are arranged along the moving direction of the telescopic rod 420 to indicate the position of the telescopic rod 420 and the clamping jaw 410 in the horizontal direction. When the telescopic rod 420 and the clamping jaw 410 reach the cutting station, the cutting limit switch 440 is triggered, and at this time, the telescopic rod 420 can start to extend downward; the triggering of the reset limit switch 450 indicates that the telescopic rod 420 and the clamping jaw 410 have moved away from the glass tube to avoid blocking the subsequent glass tubes. The magnetic induction switch 460 is installed on the telescopic rod 420 to indicate that the telescopic rod 420 has extended in place, and the clamping jaw 410 can perform an action to clamp the glass tube to ensure accurate clamping of the glass tube.
[0048] In an alternative solution of this embodiment, the telescopic rod 420 can be selected from an electric telescopic cylinder, a cylinder, etc., and a cylinder is preferably used to ensure efficiency.
[0049] The working process of the flame cutting device for the production of medicinal glass tubes provided in this embodiment is as follows:
[0050] The conveying assembly 200 drives the glass tube to move forward, and under the action of the rotating assembly 300, the glass tube rotates around its own axis, so that the cutting position of the glass tube is uniformly heated by the high-temperature and concentrated flame generated by the burner 100, and the cutting position of the glass tube reaches the softening point temperature.
[0051] Subsequently, the separating assembly 400 clamps the cut-off section of the glass tube and moves axially away from the remaining section of the glass tube, so as to break the glass tube from the softened cutting position to complete the cutting.
[0052] As the conveying assembly 200 continues to convey the remaining section of the glass tube, the glass tube moves to the nozzle 500, and the nozzle 500 blows out a compressed air flow towards the cut section of the glass tube to blow through the port that is closed due to heating and softening.
[0053] In this embodiment, the pressure and flow rate of the compressed air flow can be adjusted to adapt to glass tubes of different specifications.
[0054] It should be noted that when cutting the glass tube by pulling it apart, there is no need to additionally fix the remaining section of the glass tube. Since the glass tube itself is relatively long, the friction between the glass tube and the belt 310 etc. can ensure that the glass tube does not move when being pulled by the clamp 410.
[0055] The maintenance of the water cooling system and the water treatment cost also increase the production cost. Therefore, a new cutting method is needed, which can not only ensure the cutting quality, but also avoid the problems of pollution and water marks, so as to improve the cleanliness and appearance quality of the product.
[0056] The flame heating device for continuous cutting of medicinal glass tubes provided in this embodiment solves the problems of chip pollution and water marks of the existing mechanical grinding wheel cutting method through the combination of fixed flame heating, self-rotation driven by the belt 310, separation of the glass tube by the separating assembly 400, and blowing through by the compressed air flow. It can work continuously, has the advantages of high cutting quality and high production efficiency, and is suitable for large-scale production of medicinal glass tubes. At the same time, the use of the water cooling system is avoided, the equipment cost is reduced, and the maintenance of the water cooling system and the water treatment cost are eliminated.
[0057] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
