Description

Technical Field

[0001] This utility model relates to the field of wire drawing and filling machine technology, specifically a cooling device for a wire drawing and filling machine with protective function. Background Technology

[0002] For water-based injection products, the filling process includes stations such as bottle entry, filling, string sealing, and bottle exit. Among them, the string sealing station uses a filling and sealing machine to seal the product. The filling and sealing process is an important process in the pharmaceutical production process. This process is a crucial link that determines the intrinsic quality of the product. Therefore, the equipment must maintain a stable operating state during the filling process.

[0003] The utility model CN215323390U discloses a wire drawing and sealing machine. An air-infusing device, a filling device, a heating and wire drawing device, a heat dissipation device, and a detection device are sequentially arranged on a support frame. A conveyor chain is installed directly below these devices to transport ampoules. The ampoules undergo air inflation, filling, and heating and wire drawing sealing in sequence. After sealing, the heat dissipation device cools the sealed ampoules to prevent workers from being burned during packing. An infrared transmitter and receiver are used to detect whether the ampoules are missing or empty, saving manpower. Finally, the sealed ampoules are conveyed to the finished product outlet.

[0004] The above-mentioned technical solutions have several drawbacks. The drawing-sealing machine cannot automatically inspect whether the filling is qualified, and the ampoules are not cooled after drawing and sealing before being packed, which can easily burn operators and affect the sealing shape. Furthermore, after drawing and sealing, the distance between the flame nozzle and the upper plate is relatively short, resulting in a constant high-temperature flame at the drawing and sealing station. This causes the temperature of the metal components of the upper plate to gradually rise, leading to thermal deformation. Severe deformation of the upper plate and support beam causes the lower plate to deform downwards as well. Since the lower plate is close to the bottom rail, the rotating bearing on the lower plate may jam against the bottom rail, affecting the rotation of the reagent bottle. This also prevents cooling of the upper plate at the drawing and sealing position to reduce the impact of continuous high-temperature deformation. Summary of the Invention

[0005] The purpose of this invention is to provide a cooling device for a wire drawing and filling machine with protective function, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cooling device for a wire drawing and filling machine with protective function includes a body, and a cooling component is provided on the upper surface of the body near the conveying port;

[0008] The cooling assembly includes a bottom rail and a support beam located near the rear end of the upper surface of the bottom rail. A connecting rod is located near the left end of the top upper surface of the support beam. An upper back plate is located near the top of the front end of the connecting rod. The upper surface of the upper back plate is covered with heat insulation cotton, and a cooling cavity is located on the upper surface of the heat insulation cotton. A lower back plate is located below the upper back plate on the upper surface of the support beam. Several rotary bearings are located on the front end faces of both the lower back plate and the upper back plate. A nozzle bracket is located in the middle of the upper surface of the bottom rail. A nozzle pipe is located at the end of the nozzle bracket. Several flame nozzles are located on the nozzle pipe corresponding to the upper back plate.

[0009] Furthermore, a guide plate is provided on the upper surface of the machine body near the right end of the bottom rail, and a tray is provided on the upper surface of the machine body at the end of the guide plate.

[0010] In this invention, the guide plate helps to guide the sealed medicine bottles into the corresponding trays. The trays are symmetrically equipped with handles for easy carrying and handling.

[0011] Specifically, the bottom of the bottom rail fits tightly against the upper surface of the machine body and is fixedly connected by screws, and the tray is inserted into the machine body.

[0012] In this invention, the bottom rail is fixedly installed with the machine body, and the middle position of the bottom rail corresponds to the conveying port of the machine body, which facilitates the continuous feeding and conveying of medicine bottles into the bottom rail.

[0013] It should be noted that the bottom of the support beam is fixedly connected to the top of the bottom rail by screws, the bottom of the connecting rod is welded to the top of the support beam, and the lower surface of the lower support plate is symmetrically provided with columns. The top of the columns is welded to the bottom of the lower support plate, and the bottom of the columns is fixedly connected to the support beam by screws.

[0014] In this invention, the lower support plate is fixedly installed by the column and the support beam, which increases the stability of the assembly. The installation of the connecting rod helps to connect the upper support plate and provide a point of force.

[0015] Furthermore, a fixing plate is provided at the left end of the upper back plate, and the fixing plate is fixedly connected to the connecting rod by bolts. The rotating bearings are distributed at equal intervals, and the rotating bearings are rotatably connected to the corresponding upper back plate and lower back plate respectively.

[0016] In this invention, the rotary bearing is rotatably engaged with the upper and lower support plates. The rotary bearing does not affect the rotation of the medicine bottle. The fixed plate is fixed in combination with the connecting rod to achieve the upper support plate lifting engagement. The two sets of rotary bearings facilitate the flexible rotation of the medicine bottle as a whole.

[0017] It is worth noting that the width of the outer wall of the heat insulation cotton is adapted to the width of the position where the rotating bearing is installed on the upper plate, the width of the outer wall of the cooling cavity is adapted to the width of the outer wall of the heat insulation cotton, the interior of the cooling cavity is hollow, an air outlet is provided at the left end of the rear end face of the cooling cavity, and an air inlet is provided at the right end of the rear end face of the cooling cavity.

[0018] In this invention, the heat insulation cotton is made of glass fiber, which is resistant to high temperature and has a low thermal conductivity. It isolates the heat transfer between the upper plate and the cooling cavity. The air inlet pipe is connected to the external air blowing pipe, which continuously blows air into the cooling cavity to accelerate the air circulation inside the cooling cavity. The air circulation dissipates heat and reduces the deformation of the upper plate caused by high temperature.

[0019] Furthermore, the rear end face of the upper back plate is symmetrically provided with cavity fixing ears at the cooling cavity. The bottom of the cavity fixing ears is integrally formed with the upper back plate, and the height of the cavity fixing ears is adapted to the sum of the height of the heat insulation cotton from the cooling cavity.

[0020] In this invention, the cavity fixing ears facilitate the interception and connection of the heat insulation cotton and the cooling cavity, enabling the heat insulation cotton and the cooling cavity to be stably installed on the upper plate. The cooling cavity is fixedly connected to the cavity fixing ears by screws, increasing the stability of the installation.

[0021] Specifically, the bottom of the nozzle bracket is fixedly connected to the upper surface of the bottom rail by bolts, the nozzle pipe is fixedly connected to the nozzle bracket by screws, the flame nozzles are evenly distributed, and the flame nozzles and the nozzle pipe are integrally formed.

[0022] In this invention, the nozzle is connected to a gas and oxygen mixing pipeline. With the cooperation of multiple flame nozzles, the mouth of the medicine bottle is heated and sealed. After the mouth of the medicine bottle is rotated and cooled, it naturally fuses and seals the medicine bottle.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-5 This embodiment provides a technical solution:

[0036] A cooling device for a wire drawing and filling machine with protective function includes a body 1, and a cooling component 2 is provided on the upper surface of the body 1 near the conveying port;

[0037] Furthermore, the cooling assembly 2 includes a bottom rail 20 and a support beam 21 located on the upper surface of the bottom rail 20 near the rear end. The bottom of the bottom rail 20 is tightly fitted to the upper surface of the body 1 and is fixedly connected by screws. The tray 11 is inserted into the body 1.

[0038] In this invention, the bottom rail 20 is fixedly installed with the body 1, and the middle position of the bottom rail 20 corresponds to the conveying port of the body 1, which facilitates the continuous entry of medicine bottles into the bottom rail 20 for conveying and coordination.

[0039] Specifically, a connecting rod 210 is provided on the upper surface of the support beam 21 near the left end. An upper backing plate 22 is provided on the front end face of the connecting rod 210 near the top. A heat insulation cotton 23 is provided on the upper surface of the upper backing plate 22. A cooling cavity 24 is provided on the upper surface of the heat insulation cotton 23. The width of the outer wall of the heat insulation cotton 23 is adapted to the width of the position where the rotary bearing 27 is installed on the upper backing plate 22. The width of the outer wall of the cooling cavity 24 is adapted to the width of the outer wall of the heat insulation cotton 23. The interior of the cooling cavity 24 is hollow. An air outlet pipe 240 is provided on the left end of the rear end face of the cooling cavity 24. An air inlet pipe 241 is provided on the right end of the rear end face of the cooling cavity 24.

[0040] In this invention, the heat insulation cotton 23 is made of glass fiber, which is resistant to high temperature and has a low thermal conductivity. It isolates the heat transfer between the upper back plate 22 and the cooling cavity 24. The air inlet pipe 241 is connected to the external air blowing pipe. The air blowing pipe continuously blows air into the cooling cavity 24, which accelerates the air circulation inside the cooling cavity 24. The air circulation dissipates heat and reduces the deformation of the upper back plate 22 caused by high temperature.

[0041] It should be noted that a lower support plate 25 is provided on the upper surface of the support beam 21 below the upper support plate 22. The bottom of the support beam 21 is fixedly connected to the top of the bottom rail 20 by screws. The bottom of the connecting rod 210 is welded and fixed to the top of the support beam 21. Columns 250 are symmetrically provided on the lower surface of the lower support plate 25. The top of the column 250 is welded and fixed to the bottom of the lower support plate 25. The bottom of the column 250 is fixedly connected to the support beam 21 by screws.

[0042] In this utility model, the lower support plate 25 is fixedly installed to the support beam 21 via the column 250, which increases the stability of the assembly. The installation of the connecting rod 210 helps to connect the upper support plate 22 to the corresponding support plate and provide a point of force.

[0043] Furthermore, the front ends of the lower back plate 25 and the upper back plate 22 are provided with a number of rotary bearings 27. The left end of the upper back plate 22 is provided with a fixing plate 220. The fixing plate 220 is fixedly connected to the connecting rod 210 by bolts. The rotary bearings 27 are distributed at equal intervals and are rotatably connected to the corresponding upper back plate 22 and lower back plate 25 respectively.

[0044] In this utility model, the rotary bearing 27 is rotatably engaged with the upper support plate 22 and the lower support plate 25. The rotary bearing 27 does not affect the rotation of the medicine bottle. The fixed plate 220 is fixedly combined with the connecting rod 210 to achieve the upper support plate 22 lifting engagement. The two sets of rotary bearings 27 facilitate the flexible rotation of the medicine bottle as a whole.

[0045] Specifically, a nozzle support 26 is provided in the middle of the upper surface of the bottom rail 20, and a nozzle pipe 261 is provided at the end of the nozzle support 26. Several flame nozzles 262 are provided on the nozzle pipe 261 at the position corresponding to the upper support plate 22.

[0046] Secondly, a guide plate 10 is provided on the upper surface of the body 1 near the right end of the bottom rail 20, and a tray 11 is provided on the upper surface of the body 1 at the end of the guide plate 10.

[0047] In this utility model, with the cooperation of the receiving plate 10, it helps to guide the medicine bottle after the wire can is sealed to the corresponding tray 11. The tray 11 is symmetrically provided with pull handles, which makes it convenient to pick up and carry the tray 11.

[0048] It should be noted that the rear end face of the upper back plate 22 is also symmetrically provided with cavity fixing ears 221 at the cooling cavity 24. The bottom of the cavity fixing ears 221 and the upper back plate 22 are integrally formed. The height of the cavity fixing ears 221 is matched with the sum of the height of the heat insulation cotton 23 from the cooling cavity 24.

[0049] In this invention, with the cooperation of the cavity fixing ear 221, it is convenient to intercept and cooperate with the heat insulation cotton 23 and the cooling cavity 24, so as to realize the stable installation of the heat insulation cotton 23 and the cooling cavity 24 on the upper plate 22. The cooling cavity 24 is fixedly connected to the cavity fixing ear 221 by screws, which increases the stability of the installation.

[0050] Specifically, the bottom of the nozzle bracket 26 is fixedly connected to the upper surface of the bottom rail 20 by bolts, the nozzle pipe 261 is fixedly connected to the nozzle bracket 26 by screws, the flame nozzles 262 are evenly distributed, and the flame nozzles 262 and the nozzle pipe 261 are integrally formed.

[0051] In this invention, the nozzle 261 is connected to a gas and oxygen mixing pipeline. With the cooperation of multiple flame nozzles 262, the mouth of the medicine bottle is heated and sealed. After the mouth of the medicine bottle is rotated and cooled, it naturally fuses and seals the medicine bottle.

[0052] When using the cooling device of the wire drawing and filling machine with protective function in this embodiment, firstly, the bottom rail 20 with support beam 21 is fixed on the machine body 1 with receiving plate 10 and tray 11. Then, the lower back plate 25 with rotating rotary bearing 27 is fixed on the support beam 21 by column 250. The upper back plate 22 with rotating rotary bearing 27 is fixed on the connecting rod 210 by connecting rod 210. The heat insulation cotton 23 is installed on the upper back plate 22. The cooling cavity 24 with air inlet pipe 241 and air outlet pipe 240 is placed on the heat insulation cotton 23. The cooling cavity 24 is fixed to the cavity fixing ear 221 by screws. The nozzle 261 with flame nozzle 262 is fixed on the nozzle bracket 26.

[0053] When the medicine bottles discharged from the conveying port of the machine body 1 enter the bottom rail 20 in sequence, the medicine bottles are rotated horizontally at the rotating bearings 27 of the upper support plate 22 and the lower support plate 25, respectively. The medicine bottles move horizontally and rotate horizontally between the two adjacent rotating bearings 27. The flame nozzle 262 heats the mouth of the medicine bottle. After the mouth of the bottle is rotated and cooled, it naturally fuses and seals the medicine bottle. The air inlet pipe 241 is connected to the external air supply pipe, and the air outlet pipe 240 is opened to continuously accelerate the air circulation inside the cooling chamber 24. The air circulation carries away the heat and reduces the heat accumulation. With the cooperation of the heat insulation cotton 23, the heat transferred from the upper support plate 22 to the cooling chamber 24 is reduced, and the deformation of the upper support plate 22 caused by continuous heating is avoided, which would affect the rotating bearing 27 to drive the medicine bottle to rotate and cool down. The medicine bottles discharged from the end of the bottom rail 20 enter the tray 11 through the receiving plate 10 for centralized collection and processing.
