Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder packaging machine technology, and in particular to a real-time cooling device for longitudinal and transverse sealing of a powder packaging machine. Background Technology
[0002] Currently, existing powder packaging machines (such as patent publication number: CN218519875U) disclose a powder packaging machine that adjusts the position of the limiting plate by adjusting the component, which guides and limits the packaging can, preventing the packaging can from shifting or tipping. The conveyor belt moves the packaging can to the feeding pipe, and the positioning block clamps and positions the lower part of the side wall of the packaging can, improving the positional stability of the packaging can.
[0003] In the aforementioned patent, the heating temperature of the encapsulation is too high and heat dissipation cannot be achieved in time. Excessive melting will damage the film structure. In particular, high temperature causes the material to crystallize after melting during the packaging process (especially the heat sealing process), resulting in sealing contamination, unqualified sealing performance, and bag deformation. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a real-time cooling device for the longitudinal and transverse sealing of a powder packaging machine, which solves the technical problems, especially those caused by high temperatures, which lead to the crystallization or deterioration of materials after melting during the packaging process (particularly the heat sealing process), resulting in sealing contamination, unqualified sealing performance, and bag deformation.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A real-time cooling device for longitudinal and transverse sealing of a powder packaging machine includes a housing body and two drive shafts, with the same frame body arranged on the inner side of the two drive shafts.
[0007] A support plate is slidably installed on the inner side of the outer shell body, and a longitudinal sealing unit is fixedly installed on the side end of the support plate. A water inlet pipe is provided in the lower half of the longitudinal sealing unit, and a water outlet pipe is provided in the upper half of the longitudinal sealing unit.
[0008] A horizontal sealing module is located inside the frame body. The horizontal sealing module includes a front heat sealing module, a rear heat sealing module, a front condenser pipe, and a rear condenser pipe. Pre-tightening clamps are provided on the inner sides of both the front heat sealing module and the rear heat sealing module.
[0009] Preferably, two interface ends are fixedly installed on both sides of the front condenser, and the interior of each interface end is in communication with the front condenser.
[0010] Each of the interface ends has an arc-shaped structure, and a first conveying pipe is fixedly installed at the top of the interface end. Both ends of the post-condenser pipe are fixedly installed with second conveying pipes.
[0011] Preferably, a junction box is provided at the side end of the frame body, and the side end of the junction box is connected to the first conveying pipe and the second conveying pipe respectively;
[0012] Two electrically operated telescopic rods connected to the front heat sealing module are fixedly installed on the side end of the rear heat sealing module.
[0013] The inlet pipe and outlet pipe are respectively fixed to the two sides of the longitudinal sealing unit, and the interior of the longitudinal sealing unit is a hollow structure.
[0014] Compared with the prior art, the present invention has the following beneficial effects;
[0015] In this invention, the support plate drives the longitudinal sealing unit to be fixed inside the outer shell. The longitudinal sealing unit is hollow inside, and circulating cooling water is introduced through the water inlet pipe and then flows out through the water outlet pipe to form a circulation. This cooling method can keep the feeding screw related to the longitudinal sealing unit at a low temperature, preventing the material from melting due to excessive temperature, thereby ensuring the quality of the material and the packaging effect.
[0016] In this invention, the electric telescopic rod adjusts the distance between the front and rear heat-sealing modules according to the heat-sealing effect of the horizontal sealing strip. Then, the pre-tightening clamps at the top of both modules pre-clamp the material, keeping it about 2cm above the heat-sealing station to prevent it from contacting the heat-sealing strip and the front and rear heat-sealing modules, thus reducing melting due to heat. A cooling zone is formed above the pre-clamping device, and forced convection is used to lower the temperature of the material contact surface, further preventing the material from melting. The electric telescopic rod can adjust the distance between the front and rear heat-sealing modules to ensure the heat-sealing effect of the horizontal sealing strip, while the pre-tightening clamps ensure tightness during the heat-sealing process.

[0023] This application provides a real-time cooling device for the longitudinal and transverse sealing of a powder packaging machine. This effectively solves the problems caused by high temperatures, which lead to the material melting and crystallizing during the packaging process (especially the heat sealing process), resulting in sealing contamination, unqualified sealing performance, and bag deformation. The longitudinal sealing unit is hollow inside, and circulating cooling water is introduced through the water inlet pipe and then flows out through the water outlet pipe to form a circulation. This cooling method can keep the feeding screw related to the longitudinal sealing unit at a low temperature, preventing the material from melting due to excessive temperature, thereby ensuring the quality of the material and the packaging effect.
[0024] Example
[0025] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problems, especially the crystallization of materials after melting during the packaging process (particularly the heat sealing process) caused by high temperatures, resulting in sealing contamination, unqualified sealing performance, and bag deformation. The overall idea is as follows:
[0026] To address the problems existing in the prior art, this utility model provides a real-time cooling device for longitudinal and transverse sealing of a powder packaging machine, including a housing body 11 and two drive shafts 16. The same frame body 17 is provided on the inner side of the two drive shafts 16. The drive shafts 16 drive the frame body 17 to move, thereby adjusting the position and working state of the frame body 17 and the transverse sealing module installed on it. The frame body 17 provides a platform for the installation and operation of the transverse sealing module, realizing effective cooling and heat sealing of the material.
[0027] A support plate 12 is slidably installed on the inner side of the outer shell 11. A longitudinal sealing unit 13 is fixedly installed on the side end of the support plate 12. A water inlet pipe 15 is provided in the lower half of the longitudinal sealing unit 13, and a water outlet pipe 14 is provided in the upper half of the longitudinal sealing unit 13. The longitudinal sealing unit 13 has a hollow internal structure. Circulating cooling water is introduced through the water inlet pipe 15 to cool the longitudinal sealing unit 13. Then the cooling water flows out through the water outlet pipe 14 to form a circulation.
[0028] The horizontal sealing module is located inside the frame body 17. The horizontal sealing module includes a front heat sealing module 18, a rear heat sealing module 19, a front condenser 21, and a rear condenser 22. The inner sides of the front heat sealing module 18 and the rear heat sealing module 19 are provided with pre-tightening clamps. The electric telescopic rod adjusts the distance between the front heat sealing module 18 and the rear heat sealing module 19 according to the heat sealing effect of the horizontal sealing strip. Then, the pre-tightening clamps at the top of the two modules will pre-clamp the material, keeping the material about 2cm above the heat sealing station, avoiding contact with the heat sealing strip and the front and rear heat sealing modules 19, and reducing heat melting. The electric telescopic rod can adjust the distance between the front heat sealing module 18 and the rear heat sealing module 19.
[0029] Two interface ends 26 are fixedly installed on both sides of the front condenser pipe 21. The interior of each interface end 26 is interconnected with the front condenser pipe 21. Each interface end 26 has an arc-shaped structure, and a first conveying pipe 23 is fixedly installed at its top. Two conveying pipes 24 are fixedly installed at both ends of the rear condenser pipe 22. Circulating cooling water enters the front condenser pipe 21 and the rear condenser pipe 22 through the first conveying pipe 23 and the second conveying pipe 24 respectively, forming a cooling area above the pre-clamping device.
[0030] Each interface end 26 has an arc-shaped structure. A first conveying pipe 23 is fixedly installed at the top of the interface end 26. A second conveying pipe 24 is fixedly installed at both ends of the rear condenser pipe 22. The first conveying pipe 23 and the second conveying pipe 24 are respectively connected to the interface end 26 of the front condenser pipe 21 and the rear condenser pipe 22, so as to transport circulating cooling water to the front condenser pipe 21 and the rear condenser pipe 22.
[0031] A manifold box 25 is provided at the side end of the frame body 17. The side end of the manifold box 25 is connected to the first conveying pipe 23 and the second conveying pipe 24 respectively. The manifold box 25 centrally manages and distributes the cooling medium (circulating cooling water), and delivers the cooling water to each component that needs to be cooled, so as to achieve overall cooling of the device and improve the cooling effect and the working stability of the device.
[0032] Two electrically operated telescopic rods connected to the front heat-sealing module 18 are fixedly installed on the side end of the rear heat-sealing module 19;
[0033] The inlet pipe 15 and the outlet pipe 14 are fixed to the two sides of the longitudinal sealing unit 13, and the interior of the longitudinal sealing unit 13 is hollow.
[0034] Working principle:
[0035] The first step is that the device mainly consists of an outer shell 11, two drive shafts 16, a frame body 17, a support plate 12, a longitudinal sealing unit 13, and a transverse sealing module (including a front heat sealing module 18, a rear heat sealing module 19, a front condenser pipe 21, and a rear condenser pipe 22). The same frame body 17 is set inside the two drive shafts 16. The support plate 12 is slidably installed inside the outer shell 11. The longitudinal sealing unit 13 is fixedly installed at the side end of the support plate 12. The lower half of the longitudinal sealing unit 13 is provided with a water inlet pipe 15, and the upper half is provided with a water outlet pipe 14. The interior of the longitudinal sealing unit 13 is hollow.
[0036] The electric telescopic rod adjusts the distance between the front heat sealing module 18 and the rear heat sealing module 19 according to the heat sealing effect of the horizontal sealing strip. Then, the pre-tightening clamps at the top of the two modules will pre-clamp the material, keeping the material about 2cm above the heat sealing station to avoid contact with the heat sealing strip and the front and rear heat sealing modules 19, reducing heat melting. A cooling zone is formed above the pre-clamping device, and forced convection is used to reduce the temperature of the material contact surface, further preventing the material from melting.
[0037] Two condenser pipes, namely the front condenser pipe 21 and the rear condenser pipe 22, are integrated above the pre-clamping device. Circulating cooling water at 10℃ (5-15℃) is introduced into the pipes. Two interface ends 26 are fixedly installed on both sides of the front condenser pipe 21. The interior of each interface end 26 is interconnected with the front condenser pipe 21. Each interface end 26 has an arc-shaped structure, and a conveying pipe 1 23 is fixedly installed at the top. Both ends of the rear condenser pipe 22 are fixedly installed with conveying pipe 24. Circulating cooling water enters the front condenser pipe 21 and the rear condenser pipe 22 through conveying pipe 1 23 and conveying pipe 24, respectively. By using forced convection, the temperature of the material contact surface is reduced to below 40℃, further preventing the material from melting due to excessive temperature. The distance between the condenser pipe and the pre-clamping device is maintained at 3-5mm to ensure the cooling effect.
[0038] The second step is to perform cavity treatment on the longitudinal sealing unit 13. Circulating cooling water at 10℃ (5-15℃) is introduced into the cavity. The circulating cooling water enters the cavity of the longitudinal sealing unit 13 through the water inlet pipe 15 and flows out through the water outlet pipe 14 to form a circulation. This cooling method can keep the feeding screw, which is closely adjacent to the longitudinal sealing unit 13, at a low temperature, and prevent the material from being heated during contact with the feeding screw, thereby ensuring the quality of the material and the packaging effect.
[0039] Both the front heat sealing module 18 and the rear heat sealing module 19 are provided with pre-tightening clamps on their inner sides. Two electric telescopic rods connected to the front heat sealing module 18 are fixedly installed on the side end of the rear heat sealing module 19. The electric telescopic rods can adjust the distance between the front heat sealing module 18 and the rear heat sealing module 19 to ensure the heat sealing effect of the horizontal sealing strip during the heat sealing process. At the same time, the pre-tightening clamps can ensure the tightness during the heat sealing process.
[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
