Description

Technical Field

[0001] The present application relates to the technical field of heating of aluminum-plastic packaging machines, for example, to a practical heating mechanism of an aluminum-plastic packaging machine. Background Art

[0002] Aluminum-plastic packaging machine is a packaging machine mainly used for packaging solid medicines such as capsules and tablets. It generally adopts internal heating. The process flow of aluminum-plastic packaging machine is divided into discharge mechanism, heating mechanism, forming mechanism, stepping mechanism, unloading mechanism, plastic sealing mechanism, etc.

[0003] In the early process of aluminum-plastic packaging machine, the heating mechanism is particularly important, because the heating effect of the material sheet affects all subsequent processes, especially the traction operation in the process of the material sheet. The traditional heating mechanism is basically a single heating plate that directly bakes and heats the entire material sheet. Because it is fully covered, the heating area of the material sheet is the same, and the side of the material sheet is also heated by the same heating effect as the middle. In this way, the side of the material sheet shrinks due to the heat shrinkage effect, which causes the traction clamp to often interrupt the clamping of the side of the material sheet. This will cause frequent shutdowns and re-clamping, seriously affecting work efficiency. Utility Model Content

[0004] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0005] The disclosed embodiments provide a practical heating mechanism for an aluminum-plastic packaging machine to solve the problem that the side edges of a material sheet shrink due to heating temperature, resulting in interrupted clamping and affecting work efficiency.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A practical heating mechanism of an aluminum-plastic packaging machine includes a top heating group, a top lifting group, a bottom heating group, and a bottom lifting group. The top heating group and the bottom heating group are both arranged within the outer frame of the aluminum-plastic packaging machine and are respectively arranged on the upper and lower sides of the material plate. The top of the top heating group is provided with a top lifting group, and the bottom of the bottom heating group is provided with a bottom heating group. The top heating group and the bottom heating group, as well as the top lifting group and the bottom lifting group, have the same structure and are arranged in opposite directions. The top heating group is mainly composed of a main heating plate, a side heating plate, a hinge rod, and a driving sleeve. The main heating plate is located at the top of the middle position of the material plate and is mainly used to heat the middle of the material plate. The main heating plates of the top heating group and the bottom heating group simultaneously heat the middle of the top side and the bottom side of the material plate. The positions are heated simultaneously to ensure heating efficiency. Side heating plates are respectively provided on both sides of the main heating plate, and the side heating plates are respectively located at the top position of the side edges of the material plates and are used to heat the sides of the material plates. The side walls of the side heating plates are hinged to the side walls of the main heating plate, and the top of the main heating plate is connected with an adjusting screw. The top side of the side heating plate is provided with a hinge rod, and the outer side of the adjusting screw is movably sleeved with a driving sleeve. One end of the hinge rod is hinged to the corresponding top side of the side heating plate, and the other end is hinged to the side wall of the driving sleeve, thereby achieving the effect of guiding the hinge rod to flip the side heating plates up and down by rotating the driving sleeve. The main heating plate and the side heating plates are both electrically charged heating rods to achieve the heating effect, and the side heating plates are controlled by By flipping up and down, the distance between the side heating plate and the side of the material plate can be adjusted, and the temperature at which the side of the material plate is heated during the working process can be changed. In the application field, the material plate is generally PVDC material. In order to realize the blowing hole of the subsequent molding process, the heating temperature of the main heating plate to the material plate needs to be higher than 115℃. By adjusting the drive sleeve upward along the adjusting screw, the hinge rod will be driven to pull the side heating plate to flip upward, and the distance between the side heating plate and the side of the material plate will be increased. With the effect of the increased distance, the heating temperature of the side heating plate to the side of the material plate will be lower, so that during the working process, only the temperature of the middle part corresponding to the main heating plate of the material plate can always be higher than 115℃, ensuring the temperature of the molding blowing hole, and the side The temperature of the side can be regulated, and the side temperature will not be too high and affected by the heat shrinkage effect, which will affect the clamping of the subsequent traction clamp on its side, thereby ensuring the stability of the working process of the material plate, and there is no need to frequently stop the machine due to clamping problems, thereby achieving the purpose of increasing work efficiency. The top of the adjusting screw is connected to the top lifting group, and the top lifting group can adjust the screw to drive the main heating plate and the side heating plate to move up and down as a whole, so that the heating temperature of the material plate can be adjusted at any time during the working process, so that the material plates of different materials can be heated and adapted. The top lifting group and the bottom lifting group respectively adjust the distance between the top side heating group and the bottom heating group to facilitate the adjustment of the heating temperature of the material plate at any time, thereby greatly increasing practicality.

[0008] Furthermore, a rotating drum is rotatably connected to the top of the driving sleeve, and the rotating drum is connected to the adjusting screw by a threaded sleeve. Operating handles are respectively provided on both sides of the rotating drum. When the side heating plate needs to be flipped and adjusted, the staff can rotate the rotating drum through the operating handle, and then the rotating drum will drive the driving sleeve to move up and down along the adjusting screw, and then drive the side heating plate to flip through the hinge rod, so as to adjust the heating temperature of the side of the material plate and ensure practical effect.

[0009] Furthermore, the top lifting group includes a mounting frame, a servo motor, a driving gear, and a passive gear. The top of the adjusting screw extends to the inside of the mounting frame and is threadedly sleeved with a passive gear. The passive gear is meshed with the driving gear, and the driving gear is fixedly connected to the output end of the servo motor. The top of the servo motor is fixedly connected to the inner side wall of the outer frame. Under the action of the servo motor, the driving gear drives the passive gear, and then the adjusting screw is driven to rise or fall under the action of the threaded sleeve connection relationship, thereby realizing the overall rise and fall of the top heating group driven by the adjusting screw, thereby achieving the purpose of increasing practicality.

[0010] Furthermore, a positioning plate is provided on the top side of the passive gear, which is sleeved on the outside of the adjusting screw, and one end of the positioning plate extends and is fixedly connected to the inner wall of the bottom of the mounting frame. The position of the passive gear is limited by cooperating with the mounting frame to ensure that no up and down movement occurs to affect the stability of the adjusting screw.

[0011] Furthermore, limiting plates are fitted on both sides of the top heating group and the bottom heating group, and the inner walls of the limiting plates are fitted on the corresponding end sides of the main heating plates. The limiting plates are fixedly connected to the inner walls of the outer frame. The positions of the main heating plates on the upper and lower sides of the material plate are limited by the limiting plates to prevent them from swinging during the lifting operation and affecting the heating effect.

[0012] Furthermore, a forming assembly is provided on one side of the top heating group and the bottom heating group. The forming assembly is a prior art. The material plate passes through the forming assembly, and the forming assembly realizes the blow-hole forming process of the heated material plate, which facilitates subsequent loading and other processes.

[0014] 1): In the utility model, the main heating plate is located at the top of the middle position of the material plate, and is used to heat the middle of the material plate. Side heating plates are respectively provided on both sides of the main heating plate, and are used to heat the side edges of the material plate. Hinge rods are provided on the top sides of the side heating plates, and one end of the hinge rod is hinged to the top side of the corresponding side heating plate, and the other end is hinged to the side wall of the driving sleeve, so as to achieve the effect of guiding the hinge rod to flip the side heating plate up and down by rotating the driving sleeve, and thus the distance between the side heating plate and the side edge of the material plate can be adjusted, and thus the temperature of the side edge of the material plate heated during the working process can be changed, and the temperature of the side edge of the material plate will not be too high and will be affected by the heat shrinkage effect, which will affect the clamping of the subsequent traction clamp on its side edge, thereby ensuring the stability of the working process of the material plate, and there is no need to frequently stop the machine due to clamping problems, thereby achieving the purpose of increasing work efficiency;

[0023] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0024] A practical heating mechanism for an aluminum-plastic packaging machine includes a top heating group 1, a top lifting group 2, a bottom heating group 3, and a bottom lifting group 4. The top heating group 1 and the bottom heating group 3 are both arranged within an outer frame 6 of the aluminum-plastic packaging machine and are respectively arranged on the upper and lower sides of a material plate 7. The top lifting group 2 is provided on the top of the top heating group 1, and the bottom heating group 3 is provided on the bottom of the bottom heating group 3. The top heating group 1 and the bottom heating group 3, as well as the top lifting group 2 and the bottom lifting group 4, all have the same structure and are arranged in opposite directions.

[0025] The top heating group 1 is mainly composed of a main heating plate 11, a side heating plate 12, a hinge rod 13, and a drive sleeve 14. The main heating plate 11 is located at the top of the middle position of the material plate 7, and is mainly used to heat the middle part of the material plate 7. The main heating plates 11 of the top heating group 1 and the bottom heating group 3 heat the top side and the middle position of the bottom side of the material plate 7 at the same time to ensure heating efficiency. Side heating plates 12 are respectively provided on both sides of the main heating plate 11. The side heating plates 12 are respectively located at the top position of the side edges of the material plate 7 and are used to heat the sides of the material plate 7. The side walls of the side heating plates 12 are hinged to the side walls of the main heating plate 11. An adjusting screw 16 is connected to the top of the main heating plate 11, and a hinge rod 13 is provided on the top side of the side heating plate 12. The outer side of the adjusting screw 16 is movably sleeved with a drive sleeve 14. One end of the hinge rod 13 is hinged to the top side of the corresponding side heating plate 12, and the other end is hinged to the side wall of the driving sleeve 14, so that the hinge rod 13 can be guided to flip the side heating plate 12 up and down by rotating the driving sleeve 14. The top of the driving sleeve 14 is rotatably connected to a rotating drum 141, and the rotating drum 141 is connected to the adjusting screw 16 by a threaded sleeve. Operating handles 15 are respectively provided on both sides of the rotating drum 141. When it is necessary to flip and adjust the side heating plate 12, the staff can rotate the rotating drum 141 through the operating handle 15, and then the rotating drum 141 will drive the driving sleeve 14 to move up and down along the adjusting screw 16, and then drive the side heating plate 12 to flip through the hinge rod 13, so as to adjust the heating temperature of the side of the material plate 7 and ensure practical effects.

[0026] The main heating plate 11 and the side heating plate 12 are both electrically charged heating rods to achieve the heating effect. By controlling the side heating plate 12 to flip up and down, the distance between the side heating plate 12 and the side of the material plate 7 can be adjusted, thereby changing the temperature at which the side of the material plate 7 is heated during the working process. In the application field, the material plate 7 is generally PVDC material. In order to achieve the blowing hole of the subsequent molding process, the main heating plate 11 needs to heat the material plate 7 to a temperature exceeding 115°C. By adjusting the drive sleeve 14 upward along the adjusting screw 16, the hinge rod 13 will be driven to pull the side heating plate 12 upward. The movement will increase the distance between the side heating plate 12 and the side edge of the material plate 7. The effect of the increased distance will cause the side heating plate 12 to heat the side edge of the material plate 7 to a lower temperature. Therefore, during the working process of the material plate 7, only the temperature of the middle part corresponding to the main heating plate 11 can always be higher than 115°C, ensuring the temperature of the forming blow hole. The side edge can regulate the temperature, and will not cause the side edge temperature to be too high and suffer from the heat shrinkage effect, which will affect the subsequent clamping of the side edge by the traction clamp, thereby ensuring the stability of the working process of the material plate 7 and eliminating the need for frequent shutdowns due to clamping problems, thereby achieving the purpose of increasing work efficiency.

[0027] The top of the adjusting screw 16 is connected to the top lifting group 2. The top lifting group 2 can adjust the screw 16 to drive the main heating plate 11 and the side heating plate 12 to move up and down as a whole, so that the temperature of the material plate 7 can be adjusted at any time during the working process, so that the material plates 7 of different materials can be heated and adapted. The top lifting group 2 and the bottom lifting group 4 respectively adjust the distance between the top side heating group and the bottom heating group 3 to facilitate the adjustment of the temperature of the material plate 7 at any time, thereby greatly increasing the practicality. The top lifting group 2 includes a mounting frame 21, a servo motor 22, a driving gear 23, and a passive gear 24. The top of the adjusting screw 16 extends to the inside of the mounting frame 21 and is threadedly sleeved with a passive gear 24. The passive gear 24 is meshed with the driving gear 23. The driving gear 23 is fixedly connected to the output end of the servo motor 22, and the top of the servo motor 22 is fixedly connected to the inner wall of the outer frame 6. Under the action of the servo motor 22, the driving gear 23 drives the passive gear 24, and then the adjusting screw 16 is driven to rise or fall under the action of the threaded connection relationship, thereby realizing the overall rise and fall of the top heating group 1 driven by the adjusting screw 16, thereby achieving the purpose of increasing practicality. A positioning plate 25 is provided on the top side of the passive gear 24, and the positioning plate 25 is sleeved on the outside of the adjusting screw 16, and one end extends to be fixedly connected to the inner wall of the bottom of the mounting frame 21. The position of the passive gear 24 is limited by the cooperation of the positioning plate 25 and the mounting frame 21 to ensure that no up and down movement occurs to affect the stability of the lifting and lowering of the adjusting screw 16.

[0028] Limiting plates 8 are fitted on both sides of the top heating group 1 and the bottom heating group 3. The inner walls of the limiting plates 8 are fitted on the end sides of the corresponding main heating plates 11. The limiting plates 8 are fixedly connected to the inner walls of the outer frame 6. The position of the main heating plates 11 on the upper and lower sides of the material plate 7 is limited by the limiting plates 8 to prevent them from swinging during the lifting operation and affecting the heating effect.

[0029] A forming assembly 5 is provided on one side of the top heating group 1 and the bottom heating group 3. The forming assembly 5 is a prior art. The material plate 7 passes through the forming assembly 5, and the forming assembly 5 realizes the blow-hole forming process of the heated material plate 7, which facilitates subsequent loading and other processes.
