Description

Technical Field

[0001] The utility model relates to the technical field of bag making, in particular to a linkage type heat sealing quick freezing mechanism. Background Art

[0002] Bag making is a processing process mainly used to produce various non-rigid containers, such as plastic bags, paper bags, etc. These bags are usually closed at one or both ends, and leave an opening to put in the packaged products. Plastic bags include but are not limited to OPP, PE, POF, PPE, PP, etc. In the processing of this type of material, a heat sealing mechanism is required to seal the edge of the film to form a bag structure.

[0003] After conventional heat sealers heat and seal materials such as films, high temperature will remain. On the one hand, the residual temperature will affect the material currently being processed, which may affect its sealing structure. At the same time, it will also cause the sealing of the next round of materials to be affected to varying degrees, resulting in a reduction in the sealing effect and quality.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a linkage heat-sealing quick-freezing mechanism is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a linkage type heat sealing quick freezing mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a linkage heat-sealing quick-freezing mechanism, comprising a device frame group and a cooling mechanism, an electric push rod is vertically installed in the middle of the upper end of the device frame group, and the bottom end of the electric push rod is connected to a spring buffer column, and the bottom of the spring buffer column is connected to a pressure plate assembly, and an electric heating platform is arranged directly below the pressure plate assembly, the cooling mechanism is symmetrically installed on the left and right sides of the electric heating platform, the cooling mechanism comprises an air cooler, an air pipe, a push-type valve, a touch-pressure rod and a nozzle, one side of the air cooler is vertically connected to the air pipe, and the top of the air pipe is connected to the push-type valve, and the top of the push-type valve is vertically installed with a touch-pressure rod, and the end of the push-type valve away from the air pipe is horizontally connected to the nozzle.

[0007] Furthermore, the device frame group includes a base, a support frame, a guide rail and a beam frame, the support frame is vertically installed on the left and right sides of the base, the guide rail is installed on the inner upper end of the support frame, and the beam frame is horizontally installed on the top of the support frame.

[0008] Furthermore, the support frame is arranged in an "H"-shaped structure, and the support frame is vertically fitted on the inner walls on both sides of the upper end of the support frame.

[0009] Furthermore, the electric push rod and the spring buffer column are located on the same vertical central axis, and the electric push rod and the spring buffer column are both vertically installed at the bottom of the beam frame in a bilaterally symmetrical manner.

[0010] Furthermore, the spring buffer column is vertically connected between the electric push rod and the pressure plate assembly, and the pressure plate assembly and the electric heating table are parallel to each other.

[0011] Furthermore, the pressure plate assembly includes a sealing plate, an extension frame, a pressure block and a slider, the left and right sides of the sealing plate are horizontally connected with the extension frame, and a pressure block is installed at the bottom of one end of the extension frame away from the sealing plate, and the left and right sides of the extension frame are horizontally connected with the slider.

[0012] Furthermore, the pressure block is arranged directly above the touch pressure rod, the surface structure of the slider matches the surface structure of the guide rail, and the slider and the guide rail are slidably connected.

[0013] Furthermore, the push-type valve is structurally closed by pressing the pressure rod, and the output end of the nozzle faces one side of the vertical central axis of the electric heating platform.

[0014] The utility model provides a linkage type heat sealing quick freezing mechanism, which has the following beneficial effects:

[0015] 1. The utility model is provided with a push-type valve. Under normal conditions, the push-type valve is in an open state. When the pressure rod is pressed, the push-type valve is in a closed state. Therefore, the low-temperature airflow generated by the cold air fan can be effectively arbitrarily selected for delivery or terminal according to the frequency of bag making and sealing. At the same time, the opening or closing of the above structure depends on the pressing frequency of the pressure plate assembly driven by the electric push rod. In addition, the use of the above structure can effectively avoid unnecessary cooling effect when the electric heating table heats the bag making material, thereby reducing the processing effect on the sealing. As the pressure plate assembly is separated from the electric heating table, the structural closure of the push-type valve will be released at the same time, so that the low-temperature airflow generated by the cold air fan is quickly blown to the surface of the heated and sealed bag making material, thereby realizing structural linkage and completing the effect of synchronous cooling, thereby avoiding the influence of high temperature residue on the effect of the next group of processing operations.

[0016] 2. The utility model provides guide rails symmetrically on both sides of the inner upper end of the support frame, and cooperates with the pressure blocks on both sides of the extension frame, so that the pressure plate assembly, driven by the electric push rod, performs the vertical up and down translation, and utilizes the sliding connection between the pressure blocks and the guide rails, so as to maximize the protection of the entire pressure plate assembly from left and right deviations during the up and down translation, thereby reducing the situation where the bag-making materials pressed between the pressure plate assembly and the electric heating table are not heated and sealed in place. In addition, by arranging a spring buffer column between the electric push rod and the pressure plate assembly, the elastic damping property of the spring buffer column can be utilized to alleviate the structural downward pressure caused by the pressure block on the contact pressure rod after the electric push rod pushes the pressure plate assembly downward, thereby avoiding structural damage caused by excessive downward pressure, and playing a good structural relief and protection role.

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] like Figures 1 to 4As shown, a linkage heat-sealing quick-freezing mechanism comprises a device frame group 1 and a cooling mechanism 6, an electric push rod 2 is vertically installed at the middle of the upper end of the device frame group 1, and the bottom end of the electric push rod 2 is connected to a spring buffer column 3, and the bottom of the spring buffer column 3 is connected to a pressure plate assembly 4, and an electric heating platform 5 is arranged directly below the pressure plate assembly 4, the cooling mechanism 6 is symmetrically installed on the left and right sides of the electric heating platform 5, the cooling mechanism 6 comprises a cold air blower 601, an air supply pipe 602, a push-type valve 603, a pressure rod 604 and a nozzle 605, one side of the cold air blower 601 is vertically connected to the air supply pipe 602, and the top of the air supply pipe 602 is connected to the push-type valve 603, and the push-type valve 603 is A touch-pressure rod 604 is vertically installed on the top, and a nozzle 605 is horizontally connected to the end of the push-type valve 603 away from the air supply pipe 602. The push-type valve 603 is structurally closed by pressing the touch-pressure rod 604, and the output end of the nozzle 605 is toward the side of the vertical central axis of the electric heating table 5. Under normal conditions, the push-type valve 603 is in an open state. When the touch-pressure rod 604 is pressed, the push-type valve 603 is in a closed state. Therefore, the low-temperature airflow generated by the cold air fan 601 can be effectively selected for delivery or terminal according to the frequency of bag making and sealing. At the same time, the opening or closing of the above structure depends on the pressing frequency of the electric push rod 2 driving the pressure plate assembly 4.

[0024] like Figures 1 to 4As shown, the device frame group 1 includes a base 101, a support frame 102, a guide rail 103 and a beam frame 104. The support frames 102 are vertically installed on the left and right sides of the base 101, and the guide rail 103 is installed on the inner upper end of the support frame 102, and the beam frame 104 is horizontally installed on the top of the support frame 102. The support frame 102 is arranged in an "H" shape, and the support frame 102 is vertically fitted on the inner walls on both sides of the upper end of the support frame 102. The electric push rod 2 and the spring buffer column 3 are on the same vertical central axis, and the electric push rod 2 and the spring buffer column 3 are vertically installed at the bottom of the beam frame 104 symmetrically on the left and right. The spring buffer column 3 is vertically connected between the electric push rod 2 and the pressure plate assembly 4, and the pressure plate assembly 4 and the electric heating table 5 are parallel to each other. The pressure plate assembly 4 includes a sealing plate 401, an extension frame 402, a pressing block 403 and a slider 404. The sealing The left and right sides of the plate 401 are horizontally connected with extension frames 402, and a pressure block 403 is installed at the bottom of one end of the extension frame 402 away from the sealing plate 401, and sliders 404 are horizontally connected with the left and right sides of the extension frame 402. The pressure block 403 is arranged directly above the touch-pressure rod 604, and the surface structure of the slider 404 matches the surface structure of the guide rail 103, and the slider 404 and the guide rail 103 are slidably connected. By symmetrically arranging the guide rails 103 on both sides of the inner part of the upper end of the support frame 102 and cooperating with the pressure blocks 403 on both sides of the extension frame 402, the pressure plate assembly 4 is driven by the electric push rod 2 to perform the up and down translation in the vertical direction. The sliding connection between the pressure block 403 and the guide rail 103 is utilized, thereby ensuring to the greatest extent that the entire pressure plate assembly 4 is prevented from left and right deviation during the up and down translation.

[0025] In summary, if Figures 1 to 4 As shown, when the linkage heat-sealing quick-freezing mechanism is used, the bag-making material that needs heat-sealing processing can be moved and placed on the center of the surface of the electric heating table 5 by manual or equipment transmission, and the cold air blower 601 will keep operating synchronously and generate low-temperature airflow, which is blown out from the output end of the nozzle 605 under the transmission of the air pipe 602 and the push-type valve 603. This process can remove unnecessary impurities on the surface of the electric heating table 5 and the material to avoid affecting the heat-sealing process;

[0026] Then the electric push rod 2 at the bottom of the beam frame 104 starts to operate, and pushes the pressing plate assembly 4 connected to the bottom through the spring buffer column 3 downward in the vertical direction. At the same time, the sliders 404 on both sides of the extension frame 402 will slide synchronously along the surface of the guide rail 103 inside the upper end of the support frame 102 until the entire sealing plate 401 contacts the top surface of the electric heating table 5. Under the action of the electric push rod 2, the material will also be pressed tightly between the electric heating table 5 and the pressing plate assembly 4;

[0027] As the structure of the pressing plate assembly 4 and the electric heating platform 5 are connected, the pressing block 403 at one end of the extension frame 402 will press the contact pressure rod 604 in the vertical direction, so that the pressing valve 603 triggers the structure to close, so that the low-temperature airflow transmitted by the air pipe 602 is interrupted;

[0028] Afterwards, the electric heating table 5 is started to melt the film after heating and seal it. Subsequently, under the extension and retraction operation of the electric push rod 2, the pressure plate assembly 4 will reset its structure. As the structure of the pressure plate assembly 4 rises, the pressure rod 604 pressed by the pressure block 403 will reset synchronously, thereby releasing the closure of the push-type valve 603, allowing the low-temperature airflow to be quickly output from the open end of the nozzle 605, effectively cooling the surface of the sealed film, and then the next round of processing operations will be carried out.

[0029] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
