Description

Technical Field

[0001] This invention relates to the field of cold compress ice pack preparation technology, and in particular to a cold compress ice pack preparation system and preparation method. Background Technology

[0002] Cold compress ice packs are a type of health product that can be reused. By changing the temperature of the ingredients inside the ice pack, it can achieve both hot and cold effects. When using it, it can be applied directly to the affected or injured area. Cold compress ice packs generally have the functions of cold compress, hot compress, refrigeration and preservation, swelling reduction and cooling.

[0003] In the production process of cold compress ice packs, the first step is to prepare the ice pack body, which can be made into a bag shape by means of blown film, rolling, and cutting. Then, the ingredients required for the ice pack are sealed inside the bag by sealing the edges.

[0004] However, in the existing bag-making process, excessive wrinkles can easily occur in the bag film during the winding stage. This makes the wound bag film easily damaged when it enters the next cutting process, resulting in inconsistent bag film sizes that cannot be formed into square bags. This directly affects the subsequent processing and use of the bag film.

[0005] During the bag making process, the conveyed bag film is prone to positional deviation on the conveyor rollers, resulting in inconsistent seam positions on the wound bag film, which will directly affect subsequent production.

[0006] To this end, the inventors designed and developed a cold compress ice pack preparation system and its preparation method, which can avoid wrinkles and positional shifts during the bag film transportation process in the preparation of cold compress ice packs. Summary of the Invention

[0011] Preferably, the balance frame is provided with a hanger, the hanger is provided with a truss, and the truss is provided with a connecting plate for connection with the crane.

[0012] Preferably, the hanger is provided with a guide groove, a transverse frame is movably fitted on the guide groove, and a wire groove sleeve is provided on the transverse frame.

[0013] Preferably, the end of the transverse frame is provided with a limiting mechanism, which includes a connecting column connected to the end of the transverse frame, a buffer rod movably mounted on the connecting column, a return spring connected to the inner cavity of the connecting column at one end of the buffer rod, and a sticking roller support foot that contacts the surface of the film conveying roller at the other end of the buffer rod.

[0014] Preferably, an adjusting shaft is rotatably mounted on the hanger, and both ends of the adjusting shaft are provided with internal threaded grooves that are threaded into the threaded groove sleeve. One end of the adjusting shaft is provided with a drive motor fixed on the hanger.

[0015] Preferably, the truss is provided with a gearbox and a rotary motor. The gearbox is provided with an input shaft connected to the power shaft of the rotary motor, and the gearbox is also provided with an output shaft connected to the rotary shaft. The gearbox is provided with gear sets that are respectively connected to the input shaft and the output shaft.

[0016] Preferably, both ends of the truss are provided with cleaning mechanisms. The cleaning mechanism includes an assembly frame connected to the end of the truss. A horizontal plate frame is provided on the assembly frame. An adjusting screw is threaded onto the horizontal plate frame. An installation plate is provided at the bottom end of the adjusting screw. A screw cap is provided at the top end of the adjusting screw. Brushes that act on the surface of the wrinkle strip and the surface of the conveyor belt are provided on the installation plate.

[0017] Preferably, the cleaning mechanism further includes a suction pipe connected to the top of the mounting plate, and a dust suction port connected to the suction pipe is provided at the bottom of the mounting plate. The suction pipe is connected to an external suction device.

[0018] A method for preparing a cold compress ice pack includes the following steps:

[0019] S1: The raw materials for bag making are processed by the cutting device;

[0020] S2: The processed raw materials are processed by the bag making mechanism, and the raw materials are sequentially conveyed through the blown film machine, bag film guide, film feeding roller and winding machine to the winding roller for winding. After winding, the bag roll is cut into the shape of a cold compress ice pack.

[0021] S3: The ingredients loaded in the bag are mixed by the dispensing device, and then the processed ingredients are filled into the cold pack by the filling device.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. By using the conveyor belt and the gear set, input shaft and output shaft inside the gearbox, the wrinkle-smoothing strip can be driven to act on the surface of the bag film to smooth out the wrinkles on the surface of the bag film and avoid material damage caused by the wrinkles in subsequent processing.

[0028] 2. By setting up a limiting mechanism, and utilizing the cooperation between the adjusting shaft, drive motor, transverse frame and wire groove sleeve frame, the two transverse frames can move synchronously close to each other or far apart, so that the distance between the two limiting mechanisms can be adjusted, so that the sticking roller support can limit the position of the bag film of different sizes conveyed by the film feeding roller.

[0029] 3. By setting up a cleaning mechanism, the conveyor belt drives the rotation of the arc strip, so that both the pleating strip and the conveyor belt can come into contact with the brush bristles. This allows the brush bristles to remove dust and adhering substances from the surface of the conveyor belt and the surface of the pleating strip, reducing the impact of dust or adhering substances on the smoothing operation of the pleating strip on the bag film.

[0030] 4. By setting up the suction tube and connecting it with the dust inlet, the dust and debris swept down by the brush can enter the external suction device through the dust inlet and the suction tube in sequence.

[0031] 5. By utilizing the crane setup and the coordination between the crane, connecting plate, and truss, the distance between the conveyor belt and the film feeding roller can be adjusted, thereby adjusting the gap between the crease strip and the film feeding roller to meet the smoothing operation of bags of different thicknesses.

[0032] In summary, this invention overcomes the shortcomings of the prior art and has a reasonable design. During the bag making process, the rollers convey the bag film to smooth out surface wrinkles, avoiding damage to the bag film caused by wrinkles in later processing. It has high social use value and application prospects. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1

[0051] Reference Figure 1-14 A cold compress ice pack preparation system includes a material opening device, a bag making mechanism, a material dispensing device, a filling device, and a sealing and packaging device. The bag making mechanism includes a film frame 100, a blown film machine 200, a bag film guide frame 300, a winding machine 400, a crane 500, a film feeding roller 1, and a conveyor belt 5. The film feeding roller 1 is rotatably mounted on the winding machine 400. The crane 500 is located directly above the film feeding roller 1. The conveyor belt 5 is located between the crane 500 and the film feeding roller 1. The conveyor belt 5 is provided with an arc-shaped strip 6, and the arc-shaped strip 6 is provided with a wrinkle-reducing strip 61.

[0052] The winding machine 400 is equipped with a reversing roller 4001 and a winding roller 4002.

[0053] Specifically, the conveyor belt 5 has an internal toothed groove 51, and a transmission gear 421 that meshes with the internal toothed groove 51 is provided inside the conveyor belt 5. A rotating shaft 42 is provided on the transmission gear 421, and a balance frame 41 is provided at both ends of the rotating shaft 42. The balance frame 41 has a support frame 7 to provide surface stability for the conveyor belt 5 during rotation. The balance frame 41 has a bearing seat 411 for mounting the rotating shaft 42. There are four hangers 4, with two hangers 4 used to fix one set of balance frames 41. One set of balance frames 41 consists of two units, positioned on both sides of the conveyor belt 5. The balance frame 41 is used to cooperate with the bearing seat 411 to complete the rotational connection of the rotating shaft 42, so that the rotation of the transmission gear 421 can cooperate with its meshing with the internal tooth groove 51 to drive the conveyor belt 5 to rotate. The conveyor belt 5 located on the left side of the truss 3 rotates clockwise, and the conveyor belt 5 located on the right side of the truss 3 rotates counterclockwise. During the rotation of the conveyor belt 5, the frame 7 can provide stability to the outer surface of the conveyor belt 5, and prevent the concavity of the conveyor belt 5 from causing the position of the arc strip 6 to be inconvenient, so that the wrinkle strip 61 can contact the bag film conveyed by the film feeding roller 1.

[0054] Specifically, the balance frame 41 is equipped with a hanger 4, the hanger 4 is equipped with a truss 3, and the truss 3 is equipped with a connecting plate 2 connected to the crane 500. The connection between the crane 500 and the connecting plate 2 is used to control the working height of the truss 3, so that the gap between the wrinkle-smoothing strip 61 and the surface of the film conveying roller 1 can ensure the passage of the bag film, and allow the wrinkle-smoothing strip 61 to act on the surface of the bag film to complete the wrinkle-smoothing treatment of the bag film.

[0055] Specifically, the hanger 4 is provided with a guide slot 43, and a transverse frame 9 is movably mounted on the guide slot 43. The transverse frame 9 is provided with a threaded groove sleeve 10. The guide slot 43 allows the transverse frame 9 to perform transverse movement within it. In conjunction with the connection between the hanger 4 and the truss 3, the transverse frame 9 can be adjusted in terms of transverse movement and height position during use, and can be adjusted together with the hanger 4.

[0056] Specifically, the end of the transverse frame 9 is provided with a limiting mechanism 11. The limiting mechanism 11 includes a connecting column 1101 connected to the end of the transverse frame 9. A buffer rod 1102 is movably mounted on the connecting column 1101. One end of the buffer rod 1102 is provided with a return spring 1103 connected to the inner cavity of the connecting column 1101. The other end of the buffer rod 1102 is provided with a sticking roller support 1104 that contacts the surface of the film conveying roller 1. By setting the limiting mechanism 11, the width of the bag film can be limited during the conveying process of the film conveying roller 1, so as to avoid the bag film from shifting position when it is conveyed on the film conveying roller 1. In addition, the return spring 1103 can be elastically adjusted according to the flatness of the surface of the film conveying roller 1, so that the bottom surface of the sticking roller support 1104 is always in contact with the surface of the film conveying roller 1.

[0057] Specifically, an adjusting shaft 8 is rotatably mounted on the hanger 4. Both ends of the adjusting shaft 8 are provided with internal threaded grooves 801 that are threaded into the threaded groove sleeve 10. One end of the adjusting shaft 8 is provided with a drive motor 81 fixed on the hanger 4. Through the setting of the threaded groove sleeve 10, the drive motor 81 drives the adjusting shaft 8 to rotate, so that the threaded groove sleeve 10 can drive the two transverse moving frames 9 to move synchronously close to each other or far apart.

[0058] Specifically, the truss 3 is equipped with a gearbox 12 and a rotary motor 121. The gearbox 12 is equipped with an input shaft 1201 connected to the power shaft of the rotary motor 121, and an output shaft 1202 connected to the rotary shaft 42. The gearbox 12 is equipped with gear sets that are respectively connected to the input shaft 1201 and the output shaft 1202. Through the gearbox 12, the rotation of the conveyor belt 5 can be powered by the rotary shaft 42 and the transmission gear 421, so that the two conveyor belts 5 can rotate synchronously in opposite directions.

[0059] Example 2

[0060] Reference Figure 1-14 The difference between this embodiment and embodiment 1 is that a cleaning mechanism 13 is provided at both ends of the truss 3. The cleaning mechanism 13 includes an assembly frame 1301 connected to the end of the truss 3. A horizontal plate frame 1302 is provided on the assembly frame 1301. An adjusting screw 1303 is threaded onto the horizontal plate frame 1302. An installation plate 1305 is provided at the bottom end of the adjusting screw 1303. A screw cap 1304 is provided at the top end of the adjusting screw 1303. A brush bristle 1307 is provided on the installation plate 1305 to act on the surface of the wrinkle strip 61 and the surface of the conveyor belt 5. By using the cleaning mechanism 13, the brush bristle 1307 can contact the surface of the conveyor belt 5 and the surface of the wrinkle strip 61 during the rotation of the conveyor belt 5 and the curved strip 61, so as to clean the dust on the surface of the conveyor belt 5 and the surface of the wrinkle strip 61 and prevent the dust from sticking to the bag film.

[0061] Specifically, the cleaning mechanism 13 also includes a suction pipe 1308 connected to the top of the mounting plate 1305. The bottom of the mounting plate 1305 is provided with a dust suction port 1306 connected to the suction pipe 1308. The suction pipe 1308 is connected to an external suction device. Through the connection between the suction pipe 1308 and the external suction device, the dust swept down by the brush bristles 1307 can enter the suction pipe 1308 through the dust suction port 1306 and be drawn away.

[0062] Other undescribed structures are described in Example 1.

[0063] Example 3

[0064] Reference Figure 1-4 A method for preparing a cold compress ice pack includes the following steps:

[0065] S1: The raw materials for bag making are processed by the cutting device;

[0066] S2: The processed raw materials are processed by the bag making mechanism, and the raw materials are sequentially conveyed through the blown film machine 200, the bag film guide frame 300, the film conveying roller 1 and the winding machine 400 to the winding roller 4002 for winding. After winding, the bag roll is cut into the shape of a cold compress ice pack.

[0067] S3: The ingredients loaded in the bag are mixed by the dispensing device, and then the processed ingredients are filled into the cold pack by the filling device.

[0068] S4: Perform light inspection on the cold compress ice pack and simultaneously remove air bubbles from the cold compress ice pack to ensure that there are no air bubbles inside the pack;

[0069] S5: The filled cold packs are sealed and packaged using a sealing and packaging device;

[0070] S6: Conduct finished product testing on the sealed and packaged cold compress ice packs;

[0071] S7: After the cold compress ice pack passes the inspection, it will be put into storage.

[0072] Working principle: In this invention, the raw materials for bag making are first processed by the cutting device, and then the processed raw materials are fed into the blown film machine 200. The blown film machine 200 blows the film onto the bag film guide 300. The bag film guide 300 squeezes the bag film blown out by the blown film machine 200, so that the squeezed bag film can be conveyed to the winding roller 4002 through the reversing roller 4001 and the film feeding roller 1 in sequence. The winding roller 4002 winds up the film and cuts the wound bag film into individual cold packs. The ice packs are fixed on the filling device, and the ingredients configured by the dispensing device are filled into the cold packs. Then, the cold packs loaded with ingredients are inspected by light and air bubble removal. After passing the inspection, the cold packs can be sealed and packaged. Then, the packaged cold packs are inspected as finished products. After passing the inspection, they are put into storage.

[0073] During the bag-making process, the bag film passes over the surface of the film feeding roller 1 and passes through the gap between the wrinkle-smoothing strip 61 and the film feeding roller 1. During the process of the film feeding roller 1 conveying the bag film, the rotary motor 121 needs to be turned on to drive the input shaft 1201 to rotate. Through the gear set inside the gearbox 12, the two output shafts 1202 can rotate synchronously in opposite directions, so that the arc strips 6 on the conveyor belts 5 on both sides of the bottom of the truss 3 can cooperate with the wrinkle-smoothing strip 61 to smooth the wrinkles of the bag film. During the smoothing process, the wrinkle-smoothing strip 61 can move from the middle of the bag film to both sides, thereby eliminating the wrinkles on the surface of the bag film conveyed by the film feeding roller 1.

[0074] When conveying bags of different sizes via the surface of the film conveying roller 1, the rotation of the drive motor 81 power shaft can be controlled to drive the adjustment shaft 8 to rotate, thereby driving the thread groove sleeve 10 threaded on the inner thread groove 801 to drive the two transverse frames 9 to move synchronously away from or close to each other. The guide groove 43 provides guidance and balance for the displacement of the transverse frames 9, and is used to adjust the position of the cleaning mechanism 13 on the surface of the film conveying roller 1. The distance between the two cleaning mechanisms 13 indicates the width of the bag conveyed via the surface of the film conveying roller 1, avoiding wrinkles caused by positional deviation of the bag during conveying.

[0075] When the conveyor belt 5 drives the wrinkle-smoothing strips 61 on the arc-shaped strip 6 to smooth the bag film, the suction pipe 1308 connected to the external suction equipment can drive the dust suction port 1306 to act on the outer surface of the conveyor belt 5, and the bristles 1307 can clean the surface of the conveyor belt 5. The dust and impurities that are swept off will be extracted by the external suction equipment through the dust suction port 1306 and the suction pipe 1308 to clean the outer surface of the conveyor belt 5. When the wrinkle-smoothing strips 61 pass through the bristles 1307, they will also be cleaned by the bristles 1307. The dust and impurities that are swept off will also be extracted by the external suction equipment through the dust suction port 1306 and the suction pipe 1308.
