Description

Technical Field

[0001] This application relates to the technical field of vial manufacturing, and in particular to a device for reducing the temperature of the whole vial by changing the heating sequence. Background Art

[0002] Currently, vials, also known as: borosilicate glass or soda-lime glass controlled (molded) injection vials, are small vials sealed with rubber stoppers and aluminum-plastic combination caps. Penicillin was mostly filled in them in the early days, so they are named vials.

[0003] In the existing process of processing vials, there is a step: plastifying the position of the vial neck; the general processing method for heating and plastifying the vial neck is uniformly: first, use a flame to heat the bottle mouth, second, heat the neck, third and fourth steps continue to heat the bottle mouth, and fifth step extrude and plastify the neck.

[0004] The above-mentioned existing technical solutions have the following defects: The above processing technology is mainly applicable to heating most specifications of vials. Therefore, the position of the flame tube that sprays the flame on the machine body is in a fixed state and cannot be adjusted. And the above process is mainly to heat the bottle mouth multiple times before plastifying the neck when heating large-diameter vials, so as to avoid bottle explosion; however, for small-diameter vials, the neck is heated in the second step and the neck is plastified until the fifth step. It is necessary to ensure that the neck still maintains the plastifying temperature after the second step of heating the neck, resulting in energy waste. Summary of the Utility Model

[0005] In order to plastify the neck of a small-diameter vial, this application provides a device for reducing the temperature of the whole vial by changing the heating sequence of the vial, so as to achieve the effect of reducing production energy.

[0006] The above technical object of this application is achieved through the following technical solutions:

[0007] A device for reducing the temperature of the whole vial by changing the heating sequence, wherein an adjustable clamping assembly is provided on the machine body. The clamping assembly is used for clamping the flame tube, and can adjust the spraying angle of the flame tube on the vial and the distance between the nozzle of the flame tube and the vial.

[0008] By adopting the above scheme, the position of the flame tube spraying on the vial can be adjusted by adjusting the clamping assembly. When the vial processed by the machine body has a small diameter, the height of the flame in the second step is adjusted to align with the position of the mouth of the vial, and the position of the height of the flame in the fourth step is adjusted to align with the position of the bottleneck of the vial. Then, after preheating the bottleneck, the bottleneck can be directly plastically deformed in the next step. Compared with the existing method of heating the bottleneck in the second step and then plastically deforming the bottleneck in the fifth step, the temperature requirement of the flame for heating the bottleneck is reduced, thus achieving the effect of reducing production energy.

[0009] Further, the clamping assembly includes a clamping frame and a connecting column. The clamping frame is fixedly connected to the machine body, and both ends of the connecting column are rotatably connected to the clamping frame. The connecting column is used to connect the flame tube.

[0010] By adopting the above scheme, by adjusting the rotation of the connecting column around the clamping frame, the flame tube can be driven to rotate synchronously, and thus the position of the nozzle of the flame tube spraying on the vial can be adjusted.

[0011] Further, both ends of the connecting column are fixedly connected with rotating rods. Rotating holes are respectively opened at positions on both sides of the clamping frame corresponding to the rotating rods. The two rotating rods are respectively rotatably connected to their corresponding rotating holes; a locking assembly is further provided on the clamping frame. The locking assembly is used to lock the relative positions of the rotating hole and the rotating rod after their relative positions are determined; both ends of the two rotating rods facing away from each other penetrate through the rotating holes.

[0012] By adopting the above scheme, the rotation of the rotating rod around the rotating hole can drive the relative rotation between the connecting column and the clamping frame, and thus drive the flame tube to rotate, and thus the heating position of the flame tube on the vial can be adjusted; the setting of the locking assembly can lock the relative positions of the rotating rod and the rotating hole after the position of the flame tube is determined, and thus lock the relative positions of the connecting column and the clamping frame, and thus lock the position of the flame tube.

[0013] Further, the locking assembly includes a locking cylinder, a locking rod and a locking pin. The locking cylinder is sleeved outside the rotating rod. The side wall of the locking cylinder is fixedly connected to the outer wall of the support frame. One end of the locking rod is fixedly connected to the inner wall of the locking cylinder. A groove is provided at the other end of the locking rod. An elastic member is arranged in the groove. One end of the elastic member is fixedly connected to the groove, and the other end of the elastic member is fixedly connected to the locking pin; a plurality of locking grooves are uniformly opened on the outer wall of the rotating rod corresponding to the locking pin, and the locking grooves are in plug-in fit with the locking pin.

[0014] Further, the locking pin includes a flat end and an arc end, and the flat end is fixedly connected to the elastic member.

[0015] By adopting the above solution, when it is necessary to adjust the relative position relationship between the connecting column and the clamping bracket, the connecting column is driven to rotate around the clamping bracket. Under the action of an external force, the rotating rod rotates around the rotating hole. During the process of the rotating rod rotating around the rotating hole, the side wall of the rotating rod applies a force to the locking pin in the direction close to the groove, and the locking pin contracts in the groove. When the relative position between the connecting column and the clamping bracket is determined, and at this time the position where the flame tube drives the heating of the vial is determined, at this time the locking pin is exactly opposite to one of the locking grooves opened on the rotating rod. Under the push of the elastic member, the locking pin tightly abuts against the locking groove, thereby fixing the relative position between the rotating rod and the locking cylinder. Since the locking cylinder is fixedly connected to the clamping bracket, further limiting the relative position relationship between the rotating rod and the clamping bracket, and further limiting the relative position relationship between the connecting column and the clamping bracket, and further fixing the angle of the flame tube for heating the vial.

[0016] Furthermore, a sliding hole is opened on the side wall of the connecting column, and both ends of the sliding hole penetrate through both sides of the connecting column. The flame tube is inserted into the sliding hole and is slidably connected with the sliding hole; a fixing component is arranged on the connecting column for locking the relative position between the sliding hole and the flame tube.

[0017] Furthermore, the fixing component includes a pushing member and a pressing block. One end of the pushing member is fixedly connected to the side wall of the sliding hole, the other end of the pushing member is fixedly connected to the pressing block, and the other end of the pressing block abuts against the flame tube.

[0018] Furthermore, a handrail rod is fixedly connected to one end of the pressing block close to the pushing member, and the other end of the handrail rod passes through the pushing member and the side wall of the sliding hole.

[0019] By adopting the above solution, pulling the handrail rod in the direction away from the flame tube, at this time the handrail rod drives the pressing block to disengage from the flame tube, thereby enabling the flame tube to slide in the sliding hole, and further enabling the control of the distance between the flame tube and the vial; when the relative position between the flame tube and the sliding hole is determined, releasing the handrail rod, at this time the pushing member drives the pressing block to move in the direction close to the flame tube under its own elastic action, thereby pushing the flame tube tightly against the inner wall of the sliding hole, and further locking the relative position relationship between the flame tube and the sliding hole.

[0020] Furthermore, a pulling ring is fixedly connected to one end of the handrail rod away from the elastic member.

[0021] By adopting the above solution, the setting of the pulling ring facilitates pulling the handrail rod to slide along the sliding hole.

[0022] In summary, the present application has the following technical effects:

[0023] 1. By providing a clamping assembly, the position of the flame tube spraying on the vial can be adjusted by adjusting the clamping assembly. When the vials processed by the machine body are of small caliber, the height of the flame in the second step is adjusted to align with the mouth of the vial, and the position of the flame height in the fourth step is adjusted to align with the bottleneck of the vial. Then, after preheating the bottleneck, the bottleneck can be directly plastically deformed in the next step. Compared with the existing method of heating the bottleneck in the second step and then plastically deforming the bottleneck in the fifth step, the temperature requirement of the flame for heating the bottleneck is reduced, thereby achieving the effect of reducing production energy.

[0024] 2. By providing a handrail, pulling the handrail away from the flame tube, at this time the handrail drives the pressing block to disengage from the flame tube, so that the flame tube can slide in the sliding hole, and thus the distance between the flame tube and the vial can be controlled; when the relative position between the flame tube and the sliding hole is determined, release the handrail, at this time the pushing member drives the pressing block to move towards the flame tube under its own elastic force, and then pushes the flame tube tightly against the inner wall of the sliding hole, thereby locking the relative position relationship between the flame tube and the sliding hole.

[0025] 3. By providing a locking assembly, under the push of the elastic member, the locking pin tightly abuts against the locking groove, thereby fixing the relative position between the rotating rod and the locking cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

In the present embodiment, four clamping assemblies 2 are provided, and each clamping assembly 2 clamps a flame tube 1.

[0041] Reference Figure 1 - Figure 2 Each clamping assembly 2 includes a clamping frame 21 and a connecting column 22. The clamping frame 21 is U-shaped as a whole and has an opening facing upward. The bottom wall of the clamping frame 21 is fixedly connected to the body, and rotating holes are provided on both sides of the clamping frame 21. Rotating rods 221 are fixedly connected on both sides of the connecting column 22. Each rotating rod 221 is rotatably connected to the corresponding rotating hole, and the ends of the two rotating rods 221 that are away from each other pass through two rotating holes; a locking assembly 3 is arranged between the rotating rod 221 and the rotating hole, and the locking assembly 3 is used to lock the relative position relationship between the rotating rod 221 and the rotating hole after the relative position relationship between the rotating rod 221 and the rotating hole is determined.

[0043] Reference Figure 1 and Figure 5 A sliding hole is opened in the middle of each connecting column 22, and both ends of the sliding hole pass through the side walls of the connecting column 22. The flame tube 1 is inserted into the sliding hole, and the flame tube 1 is slidably connected with the sliding hole. A fixing component 4 is arranged between each flame tube 1 and the sliding hole. The fixing component 4 is used to lock the relative position relationship between the flame tube 1 and the sliding hole after the relative position relationship between the flame tube 1 and the sliding hole is determined.

[0044] Reference Figure 5, each fixed component 4 includes a pushing member 41 and a pressing block 42. One end of the pushing member 41 is fixedly connected to the side wall of the sliding hole, and the other end of the pushing member 41 is fixedly connected to the pressing block 42. The end of the pressing block 42 away from the pushing member 41 abuts against the flame tube 1, so as to be able to push tightly between the flame tube 1 and the sliding hole, and thus be able to lock the relative positional relationship between the flame tube 1 and the sliding hole; One end of each pressing block 42 close to the pushing member 41 is fixedly connected with a handrail rod 5. The other end of the handrail rod 5 passes through the pushing member 41 and the side wall of the sliding hole. One end of each handrail rod 5 away from the elastic member 33 is fixedly connected with a pulling ring 51; By pulling the pulling ring 51 in the direction away from the flame tube 1, the pulling ring 51 can drive the handrail rod 5 to pull the pressing block 42 away from the flame tube 1, so as to control the sliding of the flame tube 1 in the sliding hole and control the distance between the flame tube 1 and the vial; In this embodiment, the pushing member 41 is selected as a spring.

[0045] The implementation principle of the device for reducing the temperature of the whole bottle by changing the heating sequence in the embodiment of the present application is as follows: Pull the pulling ring 51 in the direction away from the flame tube 1. The pulling ring 51 can drive the handrail rod 5 to pull the pressing block 42 away from the flame tube 1, so as to control the sliding of the flame tube 1 in the sliding hole and then adjust the distance between the flame tube 1 and the vial; Then release the pulling ring 51. At this time, the pushing member 41 drives the pressing block 42 to move towards the flame tube 1 under its own elastic action, so as to push tightly between the flame tube 1 and the inner wall of the sliding hole, and thus lock the relative positional relationship between the flame tube 1 and the sliding hole; Repeat the above steps to adjust the distances between the four flame tubes 1 and the vial respectively; Then adjust the angles of the flame tubes 1 in the three steps of S1, S2, and S3, drive the connecting column 22 to rotate around the clamping frame 21. Under the action of an external force, the rotating rod 221 rotates around the rotating hole. During the rotation of the rotating rod 221 around the rotating hole, the side wall of the rotating rod 221 applies a force to the locking pin 34 in the direction close to the groove. The locking pin 34 contracts in the groove. When the relative position between the connecting column and the clamping frame 21 is determined, that is, the flame tube 1 is horizontally aligned with the mouth of the vial, at this time, the locking pin 34 is exactly opposite to one of the locking grooves 2211 opened on the rotating rod 221. Under the pushing of the elastic member 33, the locking pin 34 tightly abuts against the locking groove 2211, so as to fix the position between the rotating rod 221 and the locking cylinder 31, and thus determine the relative positional relationship between the connecting main body and the clamping frame 21, and then determine the position of the flame tube 1; Adjust in step S4 according to the above method so that the flame tube 1 corresponds to the bottleneck of the vial.

[0046] Through the above settings, the three steps of S1 - S3 uniformly heat the bottle mouth, the step of S4 heats the bottleneck, and then S5 immediately plastifies the bottleneck. The flame tube 1 for heating the bottleneck and the working station for plastifying the bottleneck are only separated by one, reducing the time for the temperature of the bottleneck part to drop after using the flame tube 1 to heat the bottleneck. Thus, the requirement for the flame temperature when heating the bottleneck is reduced. Furthermore, when plastifying the bottleneck of the vial, the temperature of the flame is reduced, saving energy.

[0047] Moreover, by processing in the above - mentioned manner, the overall temperature of the vial is reduced. The molecules of the vial will be more stable at a lower temperature. Therefore, the production with temperature reduction can also improve the stability of the vial and increase the yield of finished products.
