It includes a heating assembly for heating and drying both sides of the water-soluble film. The heating assembly includes two side plates horizontally opposite each other, positioned above the side guard plates of the water-soluble film conveying mechanism.

Description

Technical Field

[0001] This utility model relates to the field of water-soluble film production technology, specifically to a water-soluble film production device that facilitates stable heating. Background Technology

[0002] Water-soluble membranes, as an environmentally friendly functional material, have wide applications in various fields such as pharmaceuticals, pesticides, and detergent packaging. In their production process, the drying stage is a crucial step affecting the final physical properties and solubility characteristics of the membrane. Currently, most common water-soluble membrane production equipment uses hot air drying, accelerating moisture evaporation by blowing air onto the membrane surface.

[0003] However, many existing drying devices struggle to achieve uniform and synchronous drying of both sides of the membrane in practical applications. They often only apply hot air to one side or employ an asymmetrical structure, resulting in inconsistent drying rates on both sides of the membrane. This can easily cause curling, deformation, or localized differences in moisture content, affecting the consistency of the finished product quality. Furthermore, the air supply of the hot air system is usually not adjustable according to the actual moisture content of the membrane, leading to energy waste and reduced production efficiency, thus presenting certain drawbacks. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a water-soluble film production device that facilitates stable heating, comprising a heating component for heating and drying both sides of the water-soluble film, the heating component comprising two side plates horizontally arranged opposite each other above the guard plates on both sides of the water-soluble film conveying mechanism, the heating component being installed above the conveying mechanism and located between the middle and the tail end.

[0005] The heating assembly also includes a roller mechanism disposed on the opposite sides of the two side plates to assist in turning the water-soluble film over, and a drying mechanism for heating and drying the water-soluble film on one side.

[0006] The heating assembly also includes a control mechanism located on opposite sides of the two side plates for adjusting the roller spacing.

[0007] With the above technical solution, four limiting grooves are provided on both side plates.

[0008] The roller mechanism includes four rotating rollers arranged between two side plates and sequentially opposite four limiting grooves. Each end of the rotating roller is threaded with a connector, and one end of the connector is rotatably connected to a sliding button, which is slidably connected in the corresponding limiting groove.

[0009] More specifically, the four limiting slides are centered on the middle of the side plate, so that the rotating rollers connected to the two limiting slides at both ends form a set of conveying mechanisms. With the cooperation of the two sets of transmission mechanisms, the water-soluble film is flipped over, and one side of the water-soluble film is conveyed in the bonding state through each set of transmission mechanisms.

[0010] With the above technical solution, an adjustment mechanism is provided on the opposite sides of the two side plates. The adjustment mechanism includes a rotating knob fixed on the axis of the back of the side plate, and a sleeve is movably sleeved on the side of the rotating knob. The sleeve is fixed on the guard plates on both sides of the water-soluble film conveying mechanism.

[0011] More specifically, by rotating the knob inside the sleeve, the tilt angle of the side plate and the roller mechanism and drying mechanism between them can be adjusted, thereby twisting the water-soluble film through the two sets of roller mechanisms, so that the water-soluble film adheres tightly to the rotating roller.

[0012] With the above technical solution, a positioning rod is threaded onto the sleeve, and one end of the positioning rod is attached to the side of the rotary knob.

[0013] More specifically, by adjusting the side plate to the appropriate angle, the positioning rod is rotated so that its bottom end is tightly attached to the corresponding position on the side of the rotating knob, thereby fixing the angle of the side plate.

[0014] The drying mechanism, as described above, includes an air delivery head positioned between every two limiting slides.

[0015] An air supply pipe is threaded between the two air supply heads opposite each other on the two side plates, and an exhaust groove is provided at the bottom of the air supply pipe.

[0016] The gas delivery head is fixed with a gas delivery hose at its tail end.

[0017] More specifically, the end of the gas delivery hose is connected to an external gas supply device, so that gas is delivered through the gas delivery hose and gas delivery head into the gas delivery pipe, and then blown to the surface of the water-soluble film through the exhaust groove opened at the bottom.

[0018] The control mechanism includes a connecting button fixed to one end of the sliding button, a control rod threaded into the connecting button, and a rotating gear fixed between every two control rods.

[0019] More specifically, when rotating the gear, the control rods at both ends rotate simultaneously. Through the reverse design of the threads of the control rods at both ends, the force of the connection between the control rod and the internal thread of the connecting button causes the connecting button to drive the rotating roller to move. This causes the rotating rollers in the two sets of transmission mechanisms to move in opposite or relative directions, adjusting the distance between the rotating rollers. This allows the conveying operation of water-soluble films of different thicknesses to be completed under stable support, preventing the water-soluble film from sinking between the two rotating rollers due to its thickness.

[0020] The control mechanism also includes a transmission gear rotatably connected inside the side plate and located between two limit grooves, which meshes with the rotating gear.

[0021] More specifically, while the rotating gear adjusts the distance between the rotating rollers, it also causes the transmission gear to rotate through meshing force.

[0022] Through the above technical solution, a flow-limiting pressure groove is opened on the side of the transmission gear, and the flow-limiting pressure groove is attached to the side of the gas transmission hose.

[0023] More specifically, when the transmission gear rotates, the pressure exerted by the side flow-limiting groove on the gas delivery hose controls the flow rate of the gas input.

[0024] Compared with the prior art, this utility model provides a water-soluble film production device that facilitates stable heating, and has the following beneficial effects: 1. This water-soluble film production device, which facilitates stable heating, has two sets of roller mechanisms and a drying mechanism installed on the side plate. The two sets of roller mechanisms convey the water-soluble film in an S-shape and single-sided contact manner. At the same time, the exhaust pipes in the two drying mechanisms are designed to exhaust upwards and downwards respectively, so that the upper and lower surfaces of the water-soluble film can be uniformly dried with hot air at the same time. This effectively improves the drying efficiency of the film and avoids the problems of film curling, deformation and local moisture content differences caused by traditional methods.

[0025] 2. This water-soluble film production device, which facilitates stable heating, can adjust the distance between the two rotating rollers and control the air flow rate through a regulating mechanism. This reduces the air flow rate when conveying thinner films with lower water content due to a larger roller distance, thus ensuring film drying while preventing excessive heating and deformation, and improving energy efficiency. Conversely, it increases the air flow rate when conveying thicker films with higher water content, ensuring that the film is fully and evenly heated and dried, further enhancing its practicality.

[0026] 3. This water-soluble film production device, which facilitates stable heating, allows the two sets of roller mechanisms to convey the water-soluble film in a tightened state by adjusting the inclination of the side plates. This avoids wrinkles in the water-soluble film and water content in the wrinkle gaps, further improving the drying efficiency and production quality of the water-soluble film.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0030] Please see Figure 1 - Figure 5 As shown, the water-soluble film production device for easy and stable heating proposed in this embodiment includes a heating component 01 for heating and drying both sides of the water-soluble film. The heating component 01 includes two side plates 1 horizontally arranged above the guard plates on both sides of the water-soluble film conveying mechanism. The heating component 01 is installed above the conveying mechanism and is located between the middle and the tail end.

[0031] The heating assembly 01 also includes a roller mechanism 2 disposed on the opposite side of the two side plates 1 to assist in turning the water-soluble film over, and a drying mechanism 3 for heating and drying the water-soluble film on one side.

[0032] The heating assembly 01 also includes a control mechanism 4 disposed on opposite sides of the two side plates 1 for adjusting the distance between the rollers.

[0033] Furthermore, four limiting grooves 11 are provided on both side plates 1.

[0034] The roller mechanism 2 includes four rotating rollers 21 disposed between two side plates 1 and sequentially opposite to four limiting slide grooves 11. Both ends of the rotating rollers 21 are threaded with joints 22, and one end of the joints 22 is rotatably connected to a sliding button 23, which is slidably connected in the corresponding limiting slide groove 11.

[0035] More specifically, the four limiting slide grooves 11 are centered on the middle of the side plate 1, so that the rotating rollers 21 connected to the two limiting slide grooves 11 at both ends form a set of conveying mechanisms. With the cooperation of the two sets of transmission mechanisms, the water-soluble film is flipped over, and one side of the water-soluble film is conveyed in the bonding state through each set of transmission mechanisms.

[0036] Furthermore, an adjustment mechanism 12 is provided on the opposite sides of both side plates 1. The adjustment mechanism 12 includes a rotating knob 121 fixed on the axis of the back of the side plate 1. A sleeve 122 is movably sleeved on the side of the rotating knob 121. The sleeve 122 is fixed on the guard plates on both sides of the water-soluble film conveying mechanism.

[0037] More specifically, by rotating the knob 121 inside the sleeve 122, the tilt angle of the side plate 1 and the roller mechanism 2 and drying mechanism 3 between them is adjusted, thereby twisting the water-soluble film through the two sets of roller mechanisms 2, so that the water-soluble film adheres tightly to the rotating roller 21.

[0038] Furthermore, a positioning rod 123 is threaded onto the sleeve 122, and one end of the positioning rod 123 is attached to the side of the rotary knob 121.

[0039] More specifically, when the side plate 1 is adjusted to an appropriate angle, the positioning rod 123 is rotated so that its bottom end is in close contact with the corresponding position on the side of the rotating knob 121, thereby fixing the angle of the side plate 1.

[0040] Furthermore, the drying mechanism 3 includes an air delivery head 31 disposed between every two limit slides 11.

[0041] An air supply pipe 32 is threaded between two air supply heads 31 opposite to the two side plates 1, and an exhaust groove 321 is provided at the bottom of the air supply pipe 32.

[0042] The end of the gas delivery head 31 is fixed with a gas delivery hose 33.

[0043] More specifically, the end of the gas supply hose 33 is connected to an external gas supply device, so that gas is fed into the gas supply pipe 32 through the gas supply head 31 via the gas supply hose 33, and then blown to the surface of the water-soluble film through the exhaust groove 321 opened at the bottom.

[0044] It should be further explained that, in the two gas supply pipes 32, the exhaust groove 321 on the side of one pipe faces upward, while the exhaust groove 321 on the side of the other pipe faces downward, so as to achieve uniform heating on both sides of the water-soluble film and complete the drying process.

[0045] Furthermore, the external gas supply device must have a temperature regulation function to ensure that the gas input into the gas supply pipe 32 is hot gas, so that when it is blown to the surface of the water-soluble membrane, the membrane surface can be dried.

[0046] In addition, the exhaust trough 321 is arranged along the length of the gas supply pipe 32, and the gas blown outward from the trough is in a fan shape, thereby blowing the water droplets on the surface of the membrane to both sides of the membrane and improving the drying efficiency.

[0047] Furthermore, the control mechanism 4 includes a connecting button 41 fixed to one end of the sliding button 23, a control rod 42 threadedly connected to the connecting button 41, and a rotating gear 43 fixed between every two control rods 42.

[0048] More specifically, when rotating the rotary gear 43, the regulating rods 42 at both ends rotate simultaneously. Through the reverse design of the threads of the regulating rods 42 at both ends, the force of the connection between the regulating rods 42 and the internal threads of the connecting button 41 is used to drive the rotating roller 21 to move, thereby causing the rotating rollers 21 in the two sets of transmission mechanisms to move in opposite or opposite directions, adjusting the distance between the rotating rollers 21, so as to meet the requirements of conveying water-soluble films of different thicknesses under stable support, and avoiding the phenomenon of water-soluble films sinking between the two rotating rollers 21 due to their thickness.

[0049] It should be further explained that during the transport of thinner water-soluble films, the distance between the two rotating rollers 21 can be increased, while during the transport of thicker water-soluble films, the distance between the two rotating rollers 21 can be reduced to improve the stable transport capability of different films.

[0050] Furthermore, the control mechanism 4 also includes a transmission gear 44 rotatably connected inside the side plate 1 and located between the two limiting slide grooves 11, the transmission gear 44 meshing with the rotating gear 43.

[0051] More specifically, while the rotating gear 43 adjusts the distance between the rotating rollers 21, it also causes the transmission gear 44 to rotate through meshing force.

[0052] Furthermore, a flow-limiting pressure groove 441 is provided on the side of the transmission gear 44, and the flow-limiting pressure groove 441 is attached to the side of the gas transmission hose 33.

[0053] More specifically, when the transmission gear 44 rotates, the force of the pressure applied to the gas delivery hose 33 by the side flow-limiting pressure groove 441 controls the flow rate of the gas input.

[0054] It should be further explained that the flow-limiting groove 441 is semi-circular, and the inner diameter of the groove matches the diameter of the gas delivery hose 33. When the flow-limiting groove 441 is completely attached to the side of the gas delivery hose 33, the gas delivery hose 33 is in a fully open state. As the transmission gear rotates, the edge of the flow-limiting groove 441 gradually presses down on the gas delivery hose 33, thereby adjusting the flow rate of the gas delivered in the gas delivery hose 33.

[0055] The working principle of the water-soluble film production device for easy and stable heating proposed in this embodiment is as follows: In use, the front end of the water-soluble film conveyed by the water-soluble film conveying mechanism passes from top to bottom between two sets of transmission mechanisms, and then the front end of the water-soluble film is fixed on the winding device equipped on the conveying mechanism. At this time, through the operation of the water-soluble film conveying mechanism and the winding device, during the process of conveying and winding the water-soluble film, while the two rotating rollers 21 in one set of transmission mechanisms are conveying the water-soluble film in a rotating state, hot air is also blown to the bottom surface of the water-soluble film through the air supply pipe 32 installed between them to dry the bottom surface of the water-soluble film. Then, while the two rotating rollers 21 in the other set of transmission mechanisms are conveying the water-soluble film in a rotating state, hot air is also blown to the top surface of the water-soluble film through the air supply pipe 32 installed between them to dry the top surface of the water-soluble film. Finally, the water-soluble film that is completely dried on both sides is wound up by the winding device.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
