Description

Technical Field

[0001] This utility model relates to the technical field of paper cup processing equipment, and in particular to a width-adaptive heat-sealing adhesive coating machine for reinforcing high-durability paper cups. Background Technology

[0002] A heat-sealing adhesive coating machine is an automated device used for packaging materials. Its main function is to quickly bond substrates such as paper and film by precisely applying hot melt adhesive (an adhesive that melts upon heating and solidifies upon cooling). In the traditional high-durability paper cup reinforcement process, the heat-sealing adhesive coating machine is mainly used to apply adhesive to key areas such as the overlapping edges of the cup body and the joint between the cup bottom and the cup. The operation involves manually adjusting the fixed coating width and position according to the dimensions of different parts of the paper cup beforehand. During production line operation, the machine heats and melts the solid hot melt adhesive, then precisely and evenly applies the adhesive strip to the designated paper area through a fixed coating die. It then quickly bonds and solidifies with another layer of material at the pressing station. This significantly enhances the sealing, leak-proofness, and overall structural strength of the paper cup, and is a key step in achieving its "high durability."

[0003] However, existing equipment often encounters the following problems during use:

[0004] Traditional leveling mechanisms are mostly fixed or have only a limited range of manual adjustment, with a fixed lateral span of the rollers. When production shifts from narrow-width to wide-width materials, machine downtime is often required, with operators painstakingly disassembling, repositioning, and reinstalling the leveling components using tools. This process is not only time-consuming and labor-intensive, but more importantly, manual adjustment makes it difficult to ensure strict horizontal alignment of two or more sets of leveling rollers, easily leading to blind spots of "misalignment" or "missed pushes." Every change in product specifications is accompanied by lengthy downtime for adjustments. Operators must perform tedious adjustments inside the high-temperature, complex equipment, a process fraught with uncertainty, making it difficult to guarantee adjustment accuracy and often requiring repeated trial and error. Utility Model Content

[0005] The main objective of this invention is to provide a width-adaptive heat-sealing adhesive coating machine for reinforcing high-durability paper cups. This effectively addresses the problem mentioned in the background art: existing traditional flattening mechanisms are mostly fixed or have only a limited manual adjustment range, with a fixed lateral span of the rollers. When switching production from narrow-width to wide-width materials, the machine often needs to be stopped, requiring operators to painstakingly disassemble, reposition, and reinstall the flattening components using tools. This process is not only time-consuming and labor-intensive, but more importantly, manual adjustment makes it difficult to ensure strict horizontal alignment of two or more sets of flattening rollers, easily leading to "misalignment" or "missed push" blind spots. This invention, through a central drive motor and gear rack mechanism, precisely controls the lateral expansion or contraction of the flattening mechanisms on both sides. When the coating width needs adjustment, no manual intervention is required; the system automatically drives the entire sleeve sliding assembly to slide outward along the slide rail, seamlessly extending the working range of the flattening rollers and solving the "blind spots" and "missed push" problems caused by manual adjustment misalignment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A width-adaptive heat-sealable adhesive coating machine for reinforcing high-durability paper cups, comprising:

[0008] Tension the coating machine body;

[0009] A crossbeam frame is located above the rollers of the tension coating machine body, and both ends of the crossbeam frame are fixedly connected to the frame of the tension coating machine body.

[0010] A vertical member, the top of which is fixedly connected to the middle section of the crossbeam frame;

[0011] A pressure-applying mechanism, which is installed on one side of the vertical member;

[0012] The leveling mechanism is provided in two sets, both sets of which are fixedly installed on the same side of the vertical member, and the two sets of leveling mechanisms are distributed in a vertically symmetrical relationship.

[0013] The leveling mechanism includes:

[0014] A slide rail, which is horizontally mounted on the side wall of the vertical member;

[0015] A sliding housing is fitted onto the slide rail;

[0016] A sliding rod, which is fixed to the hollow part of the bottom surface of the sleeve sliding shell;

[0017] A sliding element, which is slidably sleeved onto the body of the sliding rod;

[0018] An auxiliary plate, wherein the auxiliary plate is arranged horizontally, and one end of the auxiliary plate is connected to the bottom surface of the sliding member;

[0019] A linkage plate, one side of which is vertically connected to the other end of the auxiliary plate;

[0020] A roller shell, the top surface of which is laterally connected to the bottom end of the linkage plate, and the bottom end of the roller shell has a hollow structure;

[0021] A flattening roller is installed inside the roller housing.

[0022] The pressure-applying mechanism includes:

[0023] A strip-shaped opening, which is vertically formed on the vertical member;

[0024] A rack, the rack being located inside the strip-shaped opening;

[0025] A lower pressure plate, which is connected to the rack;

[0026] A drive motor is mounted on one side of the vertical member;

[0027] A drive gear is mounted on the output end of the drive motor and meshes with the rack;

[0028] Two downward pressure rods are arranged symmetrically, and one end of each downward pressure rod is movably connected to one side of the downward pressure plate;

[0029] The force-applying plate is provided in a number corresponding to the linkage plate, and one side of the force-applying plate is fixedly connected to one side of the corresponding linkage plate.

[0030] In the lower set of the pushing mechanism, the slide rod is fixed to the top surface of the sleeve slide, and the sliding member and the additional plate are located above the slide rod.

[0031] The sleeved sliding housing and the slide rail form a sliding connection.

[0032] The slider and the slide rod are in a sliding connection.

[0033] The rack and the strip-shaped opening are in a sliding connection.

[0034] The other ends of the two pressure rods are respectively connected to the corresponding force-applying plates.

[0035] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a central drive motor and gear rack mechanism to precisely control the lateral expansion or contraction of the flattening mechanisms on both sides. When the coating width needs adjustment, no manual intervention is required; the system automatically drives the entire sleeve sliding assembly to slide outward along the slide rail, seamlessly extending the working range of the flattening rollers and solving the problems of "blind spots" and "missed pushes" caused by manual adjustment misalignment. Simultaneously, this integrated drive mechanism ensures that the upper and lower flattening rollers maintain consistent height and uniform pressure at any width, thus transforming the originally tedious, experience-dependent, and imprecise manual adjustment process into a highly efficient and repeatable automated process.

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.

[0043] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] like Figure 1-4 As shown, this utility model provides a width-adaptive heat-sealing adhesive coating machine for reinforcing high-durability paper cups. The width-adaptive heat-sealing adhesive coating machine for reinforcing high-durability paper cups includes a tension coating machine body 1, a crossbeam frame 2, a vertical component 3, a pressure applying mechanism 4, a flattening mechanism 5, a slide rail 51, a sleeve sliding shell 52, a slide rod 53, a sliding component 54, an auxiliary plate 55, and a linkage plate 56.

[0045] The crossbeam frame 2 is located above the rollers of the tension coating machine body 1. Both ends of the crossbeam frame 2 are fixedly connected to the frame of the tension coating machine body 1. The top of the vertical member 3 is fixedly connected to the middle section of the crossbeam frame 2. The pressure applying mechanism 4 is installed on one side of the vertical member 3. Two sets of leveling mechanisms 5 are provided, both fixedly installed on the same side of the vertical member 3, and distributed symmetrically vertically. In the lower set of leveling mechanisms 5, the slide rod 53 is fixed to the top surface of the sleeve sliding shell 52, and the sliding member 54 and the auxiliary plate 55 are located above the slide rod 53.

[0046] In this utility model, the leveling mechanism 5 includes: a slide rail 51 horizontally mounted on the side wall of the vertical member 3; a sliding shell 52 sleeved on the slide rail 51; the sliding shell 52 and the slide rail 51 form a sliding connection; a sliding rod 53 is fixed to the hollowed-out part of the bottom surface of the sliding shell 52; a sliding member 54 is slidably sleeved on the rod body of the sliding rod 53; the sliding member 54 and the sliding rod 53 form a sliding connection; an auxiliary plate 55 is horizontally arranged, with one end of the auxiliary plate 55 connected to the bottom surface of the sliding member 54; one side of the linkage plate 56 is vertically connected to the other end of the auxiliary plate 55; the movement of the linkage plate 56 is converted into the stable linear movement of the leveling roller 58 through the guide system composed of the auxiliary plate 55 and the sliding rod 53.

[0047] In this invention, initially, the entire sliding shell 52 assembly is fixed on the slide rail 51, and the flattening roller 58 only performs linear flattening perpendicular to the paper's forward direction. When wider sheets of paper need to be processed, the lower pressure plate 43 continues to move downward. After the lower pressure rod reaches a certain angle, the horizontal thrust overcomes the static friction between the sliding shell 52 and the slide rail 51, pushing the entire sliding shell 52 assembly to slide outward along the slide rail 51, thereby extending the stroke of the flattening roller 58 and achieving adaptive expansion of the flattening width. The two flattening mechanisms 5 are arranged symmetrically, and by installing the middle set of components such as the slide rod 53 on the top surface of the sliding shell 52, the working heights of the two flattening rollers 58 are ensured to be flush, guaranteeing consistent coating quality. The top surface of the roller shell 57 is horizontally connected to the bottom end of the linkage plate 56, and the bottom end of the roller shell 57 has a hollow structure, with the flattening roller 58 installed inside the roller shell 57.

[0048] In this invention, the pressure applying mechanism 4 includes a strip-shaped opening 41 vertically formed on a vertical member 3, and a rack 42 located inside the strip-shaped opening 41. The rack 42 and the strip-shaped opening 41 are slidably connected, and a lower pressure plate 43 is connected to the rack 42. The lower pressure plate 43 converts the vertical force into a horizontal thrust through two movable lower pressure rods and transmits it to the force applying plates 47 on both sides. Since the lower pressure rods are obliquely arranged, the angle between them and the horizontal plane changes as the lower pressure plate 43 rises and falls. When the lower pressure plate 43 moves downward, the lower pressure rods tend to be horizontal, and the horizontal component of the force increases, thereby pushing the force applying plate 47 and the linkage plate 56 fixed thereto to move outward. During this process, the amount of downward movement of the lower pressure plate 43 directly controls the pressure applied to the flattening roller 58. A drive motor 44 is installed on one side of the vertical member 3. The drive motor 44, as a power source, converts the rotational motion into the vertical linear motion of the rack 42 through the meshing of the drive gear 45. The rack 42 drives the lower pressure plate 43 to move synchronously. The drive gear 45 is installed at the output end of the drive motor 44 and meshes with the rack 42. Two lower pressure rods 46 are symmetrically arranged. One end of the two lower pressure rods 46 is movably connected to one side of the lower pressure plate 43. The other end of the two lower pressure rods 46 is connected to the corresponding force application plate 47. The number of force application plates 47 corresponds to the number of linkage plates 56, and one side of the force application plate 47 is fixedly connected to one side of the corresponding linkage plate 56.

[0049] It should be noted that, in the wide-adaptive heat-sealing adhesive coating machine for reinforcing high-durability paper cups designed in this utility model, before the device is started, the initial position is that the lower pressure plate 43 is in a high position, and the lower pressure rods are relatively vertical. At this time, the two sets of flattening mechanisms 5 are in a retracted state under the action of the force plate 47 and the internal force component (such as a spring, if not described, it is considered as mechanical clearance), and the flattening roller 58 is located near the center, which is a narrow-width coating or standby state. When the coating machine starts working, when the paper carrying hot melt adhesive passes under the flattening roller 58, the drive motor 44 starts, and the drive gear 45 rotates, driving the rack 42 and the lower pressure plate 43 to move downward. The lower pressure plate 43 presses the two lower pressure rods 46, causing them to rotate around the movable connection point and tend to be horizontal. The horizontal thrust generated by the downward pressure rod pushes the force plates 47 on both sides. The force plates 47 drive the linkage plate 56, the auxiliary plate 55, and the entire roller housing 57 to move linearly outward away from the center along the guide of the slide rod 53, so that the flattening roller 58 is pressed against the coating adhesive surface, and the first stage of the flattening operation begins. If the wide paper needs to be coated, the drive motor 44 continues to work, and the downward pressure plate 43 moves further down. At this time, the horizontal thrust of the downward pressure rod on the force plate 47 continues to increase. When this force is sufficient to overcome the friction between the sleeve sliding housing 52 and the slide rail 51, the push of the downward pressure rod will cause the sleeve sliding housing 52, along with the entire internal flattening mechanism 5 including the slide rod 53, the sliding member 54, the auxiliary plate 55, the linkage plate 56, the roller housing 57, and the flattening roller 58, to slide outward along the transverse slide rail 51. This process realizes the lateral expansion of the working range of the flattening roller 58, ensuring that the hot melt adhesive at the edge of the wide paper can also be effectively flattened. When the coating operation is completed or needs to be stopped, the drive motor 44 reverses, causing the rack 42 and the lower pressure plate 43 to move upward. The lower pressure rod is lifted, increasing the angle with the horizontal plane and tending towards verticality. This action pulls the force plate 47 inward through the movable connection point, which in turn drives the linkage plate 56, the auxiliary plate 55, and the sleeve sliding shell 52 to reset along the slide rail 51 and slide rod 53 to the center position if they have been previously extended, causing the flattening roller 58 to leave the adhesive surface and return to the initial retracted position, waiting for the next work cycle.
