Description

Technical Field

[0001] This utility model relates to the technical field of packaging bag production equipment, and in particular to an automatic pressure regulating hot pressing forming equipment for food packaging bags. Background Technology

[0002] Food packaging bags are thin-film containers that come into direct contact with food and are used to hold and protect food. They are generally made of PE (polyethylene) and PP (polypropylene). During the processing of food packaging bags, heat sealing is generally used. The flat, cylindrical bag material is heat-pressed at equal intervals to create multiple seals, and then cut open with a cutting tool to obtain individual packaging bags.

[0003] Existing heat-sealing devices commonly use a single heat-sealing method, which easily leads to local leaks and cannot be matched with the structure of the food packaging bag, resulting in poor sealing effect. To address the above problems, application number 202220136488.0 discloses a heat-sealing device for food packaging bags, which includes a bottom support assembly, a top support assembly, an elastic transition assembly, a bottom heat-sealing assembly, and a top heat-sealing assembly. This heat-sealing device for food packaging bags uses an inlet support strip and an outlet support strip to form the bottom heat-sealing assembly, and uses inlet pressure strips and outlet pressure strips adapted to the shape of the inlet support strip and the outlet pressure strip to form the top heat-sealing assembly. At the same time, an adjusting rod is set in the top support seat to finely adjust the position of the inlet pressure strip and the outlet pressure strip, so that the food packaging bag is subjected to heat-sealing treatment with inlet pressure strips and outlet pressure strips of different shapes in succession during the transportation process, which matches the structure of the food packaging bag, thereby improving the sealing effect and improving product quality.

[0004] However, a thorough reading of the aforementioned patent documents reveals the following issues: When performing heat sealing, different sizes of packaging bags require different sizes and shapes of seals to be imprinted according to the needs of the enterprise. Existing methods require stopping the machine to disassemble and replace the heat press plate, which is inconvenient. Moreover, since different packaging bags have different thicknesses, the required heat pressing pressure is different, and existing methods do not have an automatic pressure adjustment mechanism, which can easily affect the quality of the packaging bags, leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic pressure-adjusting hot-pressing forming device for food packaging bags.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic pressure-adjusting hot-pressing forming equipment for food packaging bags includes a housing, an adjustment mechanism, a hot-pressing mechanism, and a control module;

[0008] The housing is equipped with a workbench, a tray is provided on the workbench, and the same food packaging bag is provided on the workbench and the tray. A horizontal plate is fixedly connected inside the housing, and multiple hot pressing mechanisms are provided on the horizontal plate. Each of the multiple hot pressing mechanisms corresponds to the food packaging bag. An adjustment mechanism is provided on the housing, which corresponds to the multiple hot pressing mechanisms. A control module is provided on the housing, and the adjustment mechanism is connected to the control module.

[0009] The adjustment mechanism includes a hydraulic cylinder, a bracket, an adjusting roller, a pusher block, and an electric motor. The hydraulic cylinder is fixedly installed on the housing. Through the cooperation of various components, it can not only perform heat embossing of different specifications and shapes on the food packaging bag, but also adjust the heat embossing pressure of the food packaging bag according to the user's needs.

[0010] Specifically, the output end of the hydraulic cylinder is fixedly connected to a bracket, and an adjusting roller is rotatably connected to the bracket. Multiple sets of push blocks are arranged on the adjusting roller, and the multiple sets of push blocks are arranged at equal intervals on the adjusting roller. The shapes of the multiple sets of push blocks on the adjusting roller are all different. Because the shapes of the multiple sets of push blocks on the adjusting roller are all different, the sliders at different positions drive the corresponding heat-conducting pressing plates to move downwards, thereby achieving the effect of heat-pressing and sealing the food packaging bags with different specifications and shapes, improving the applicability and convenience.

[0011] Specifically, an electric motor is fixedly installed on the bracket, and the output end of the electric motor is connected to one end of the adjusting roller. The output end of the electric motor drives the adjusting roller to rotate on the bracket, and one set of push blocks on the adjusting roller corresponds to multiple sliders.

[0012] Specifically, both the electric motor and the hydraulic cylinder are connected to the control module, which drives and controls the hydraulic cylinder and the electric motor.

[0013] Specifically, the hot pressing mechanism includes sliders, heat-conducting pressing plates, and springs. Multiple sliders are slidably connected to the horizontal plate. One set of pushers abuts against multiple sliders, and each set of pushers corresponds to a slider. One end of each slider is provided with a heat-conducting pressing plate, which contacts the food packaging bag. A spring is fixedly connected to the slider, and one end of the spring is fixedly connected to the horizontal plate. Activating the hydraulic cylinder causes its output end to move the support upwards. Simultaneously, the support moves the adjusting roller synchronously, and the adjusting roller moves the multiple sets of pushers downwards. One set of pushers interacts with the sliders, causing the corresponding sliders to slide downwards on the horizontal plate. This compresses the corresponding springs, and the sliders move the corresponding heat-conducting pressing plates synchronously downwards, causing the heat-conducting pressing plates to interact with the support plate, thereby achieving the effect of hot pressing the food packaging bag.

[0014] Specifically, a groove is provided on the worktable, and a pressure sensor is fixedly installed in the groove. The support plate is connected to the pressure sensor. Both the pressure sensor and the support plate correspond to multiple hot pressing mechanisms. The pressure sensor is connected to the control module. During the interaction between the heat-conducting pressing plate and the support plate, the pressure applied by the hydraulic cylinder is transmitted to the pressure sensor through the transmission of the support plate. When the pressure value of the pressure sensor reaches a preset value, the pressure sensor transmits information to the control module, causing the control module to control the hydraulic cylinder to drive in the reverse direction.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The present invention provides an automatic pressure regulating hot pressing forming equipment for food packaging bags. The output end of the motor drives the adjusting roller to rotate on the support, and one of the multiple sets of push blocks on the adjusting roller corresponds to multiple sliders. Since the shapes of the multiple sets of push blocks arranged on the adjusting roller are different, the sliders at different positions drive the corresponding heat-conducting pressing plates to move downward, thereby achieving the effect of hot pressing and sealing the food packaging bags with different specifications and shapes, improving the applicability and convenience.

[0017] (2) The automatic pressure regulating hot pressing forming equipment for food packaging bags of this utility model can adjust the pressure of hot pressing of the food packaging bags according to the user's needs through the cooperation between the worktable, control module, pressure sensor and pallet, thereby improving the applicability and product quality.

[0025] Reference Figure 1-4 An automatic pressure-adjusting hot-pressing forming device for food packaging bags includes a housing 1, an adjusting mechanism 6, a hot-pressing mechanism 5, and a control module 8.

[0026] The housing 1 is equipped with a workbench 2, on which a tray 7 is provided. The same food packaging bag 3 is provided on the workbench 2 and the tray 7. A horizontal plate 4 is fixedly connected inside the housing 1. Multiple hot pressing mechanisms 5 are provided on the horizontal plate 4. Each of the multiple hot pressing mechanisms 5 corresponds to the food packaging bag 3. An adjustment mechanism 6 is provided on the housing 1. The adjustment mechanism corresponds to the multiple hot pressing mechanisms 5. A control module 8 is provided on the housing 1. The adjustment mechanism 6 is connected to the control module 8.

[0027] The adjustment mechanism 6 includes a hydraulic cylinder 61, a bracket 62, an adjustment roller 63, a pusher block 64, and a motor 65. The hydraulic cylinder 61 is fixedly installed on the housing 1. Through the cooperation of various components, it can not only achieve the sealing effect of heat-pressing different specifications and shapes on the food packaging bag 3, but also adjust the heat-pressing pressure of the food packaging bag 3 according to the user's needs.

[0028] See attached document Figure 2-3 The output end of the hydraulic cylinder 61 is fixedly connected to a bracket 62, and an adjusting roller 63 is rotatably connected to the bracket 62. Multiple sets of push blocks 64 are arranged on the adjusting roller 63, and the multiple sets of push blocks 64 are arranged at equal intervals on the adjusting roller 63. The shapes of the multiple sets of push blocks 64 on the adjusting roller 63 are different. Because the shapes of the multiple sets of push blocks 64 on the adjusting roller 63 are different, the sliders 51 at different positions drive the corresponding heat-conducting pressing plates 52 to move downward, thereby achieving the effect of heat-pressing different specifications and shapes of sealing on the food packaging bag 3, improving the applicability and convenience. A motor 65 is fixedly installed on the bracket 62, and the output end of the motor 65 is connected to one end of the adjusting roller 63. Driven by the motor 65, the output end of the motor 65 drives the adjusting roller 63 to rotate on the bracket 62, and one set of push blocks 64 on the adjusting roller 63 corresponds to multiple sliders 51.

[0029] See attached document Figure 1 Both the electric motor 65 and the hydraulic cylinder 61 are connected to the control module 8, which drives and controls the hydraulic cylinder 61 and the electric motor 65.

[0030] See attached document Figure 2-4The hot pressing mechanism 5 includes a slider 51, a heat-conducting pressing plate 52, and a spring 53. Multiple sliders 51 are slidably connected to the horizontal plate 4. One set of push blocks 64 abuts against multiple sliders 51, and each set of push blocks 64 corresponds to a slider 51. A heat-conducting pressing plate 52 is provided at one end of each slider 51, and the heat-conducting pressing plate 52 contacts and connects to the food packaging bag 3. A spring 53 is fixedly connected to the slider 51, and one end of the spring 53 is fixedly connected to the horizontal plate 4. Activating the hydraulic cylinder 61 causes its output end to drive the support... The frame 62 moves upward, and at the same time, the support 62 drives the adjusting roller 63 to move synchronously. Simultaneously, the adjusting roller 63 drives multiple sets of push blocks 64 to move downward, and causes one set of push blocks 64 to interact with multiple sliders 51, so that the corresponding sliders 51 slide downward on the horizontal plate 4, and the corresponding springs 53 are compressed. At the same time, the sliders 51 drive the corresponding heat-conducting pressing plates 52 to move downward synchronously, and cause the heat-conducting pressing plates 52 to interact with the support plate 7, thereby achieving the effect of hot pressing the food packaging bag 3.

[0031] See attached document Figure 2 A groove is provided on the workbench 2, and a pressure sensor is fixedly installed in the groove. The support plate 7 is connected to the pressure sensor. Both the pressure sensor and the support plate 7 correspond to multiple hot pressing mechanisms 5. The pressure sensor is connected to the control module 8. During the action of the heat-conducting pressing plate 52 and the support plate 7, the pressure applied by the hydraulic cylinder 61 is transmitted to the pressure sensor through the transmission of the support plate 7. When the pressure value of the pressure sensor reaches the preset value, the pressure sensor transmits information to the control module 8, and the control module 8 controls the hydraulic cylinder 61 to drive in reverse.

[0032] Working principle: During use, the hydraulic cylinder 61 and the electric motor 65 are driven and controlled by the control module 8, and the pressure sensor box in the groove on the worktable 2 is electrically connected to the control module 8.

[0033] First, the food packaging bag 3 is placed between multiple heat-conducting pressing plates 52 and the support plate 7. Then, the hydraulic cylinder 61 is activated, causing the output end of the hydraulic cylinder 61 to drive the bracket 62 to move upward. At the same time, the bracket 62 drives the adjusting roller 63 to move synchronously. Simultaneously, the adjusting roller 63 drives multiple sets of push blocks 64 to move downward, and one set of push blocks 64 interacts with multiple sliders 51, so that the corresponding sliders 51 slide downward on the horizontal plate 4, and the corresponding springs 53 are compressed. At the same time, the sliders 51 drive the corresponding heat-conducting pressing plates 52 to move downward synchronously, and the heat-conducting pressing plates 52 interact with the support plate 7, thereby achieving the effect of hot pressing the food packaging bag 3.

[0034] During the interaction between the heat-conducting pressing plate 52 and the support plate 7, the pressure applied by the hydraulic cylinder 61 is transmitted to the pressure sensor through the transmission of the support plate 7. When the pressure value of the pressure sensor reaches the preset value, the pressure sensor transmits information to the control module 8, and the control module 8 controls the hydraulic cylinder 61 to drive in the reverse direction, thereby causing the adjusting roller 63 to return to its original state and causing its push block 64 to disengage from the corresponding slider 51. At the same time, through the elastic potential energy of the spring 53, the slider 51 returns to its original state and the heat-conducting pressing plate 52 disengages from the food packaging bag 3.

[0035] Furthermore, the pressure sensor can be used to adjust the pressure of the food packaging bag 3 during hot pressing according to the user's needs, thereby improving the applicability and product quality.

[0036] Driven by the motor 65, the output end of the motor 65 drives the adjusting roller 63 to rotate on the bracket 62, and one of the multiple sets of push blocks 64 on the adjusting roller 63 corresponds to multiple sliders 51. Since the shapes of the multiple sets of push blocks 64 arranged on the adjusting roller 63 are different, the sliders 51 at different positions drive the corresponding heat-conducting pressing plates 52 to move downward, thereby achieving the effect of heat-pressing different specifications and shapes of sealing on the food packaging bag 3, improving the applicability and convenience.

[0037] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, it can not only achieve the sealing effect of heat-pressing different specifications and shapes on the food packaging bag 3, but also adjust the heat-pressing pressure of the food packaging bag 3 according to the user's needs, thereby improving convenience and applicability. Moreover, the structure is simple and the practicality is higher.
