Description

Technical Field

[0001] This application relates to the field of woven bag manufacturing, and in particular to an inner film laminating machine for convenient transport. Background Technology

[0002] With the development of the woven bag manufacturing industry, woven tubular fabric lined with plastic film is now widely used in the market. This type of woven tubular fabric is a composite packaging bag; the outer layer is a woven layer, usually woven from ethylene-vinyl acetate flat yarns, and the inner layer is a film layer, typically composed of a continuous film blown from polyethylene. These woven bags are aesthetically pleasing, structurally strong, and offer good moisture and dust resistance.

[0003] Inner film laminating machines for processing and manufacturing the aforementioned woven bags are already available on the market. In related technologies, the inner film laminating machine includes a conveying device, a heating oven, and a cooling device. The conveying device includes two sets of conveyor rollers, with the heating oven and cooling device located between the two sets of conveyor rollers. In actual processing, the woven fabric is first directly woven and fitted onto the outer layer of the inner film. The two are then conveyed by the conveying device. Before the woven fabric and inner film enter the heating oven, the inner film is inflated by an air compressor. The heating oven heats the air inside the inner film. Because the melting point of the inner film material is lower than that of the woven fabric material, the heating oven melts the hot melt adhesive on the outer layer of the inner film, causing the inner film to bond with the woven fabric. Finally, the inner film is cooled by the cooling device.

[0004] Before using the aforementioned internal adhesive film laminating machine, the woven fabric and the inner film are typically fed manually through a set of conveyor rollers, a hot oven, a cooling device, and another set of conveyor rollers (hereinafter referred to as the initial conveying). Then, the internal adhesive film laminating machine is started for lamination. However, since the hot oven is open at both ends and has an inner cavity, but no opening in the middle, and the hot oven is quite long, manually feeding the woven fabric and the inner film for the initial conveying as described above is inconvenient and labor-intensive. Summary of the Invention

[0005] To improve the ease of initial conveying of woven fabric and inner membrane, this application provides an inner membrane laminating machine for convenient conveying.

[0006] This application provides a convenient conveying internal adhesive film laminating machine, which adopts the following technical solution: An easy-to-carry inner film laminating machine includes a hot drying oven that extends along the conveying direction of the woven fabric. The hot drying oven has openings at both ends in the extending direction and has an inner cavity. It also includes a conveying device, which includes a conveying drive source and a conveying component. The conveying drive source drives the conveying component to slide. The conveying component can slide along the extending direction of the hot drying oven within the inner cavity of the hot drying oven. The conveying component is detachably connected to the beginning of the woven fabric and the inner film.

[0007] By adopting the above technical solution, during the initial conveying of the woven fabric and inner film, the woven fabric and inner film are fixed to the conveyor at the entrance of the hot drying oven. The conveyor is driven by a conveyor drive source to slide, carrying the woven fabric and inner film through the inner cavity of the hot drying oven to the outlet, where the woven fabric and inner film are then removed from the conveyor. By setting a conveyor that can slide within the inner cavity of the hot drying oven and is detachably connected to the beginning of the woven fabric and inner film, and driven by a conveyor drive source, the initial conveying of the woven fabric and inner film into the hot drying oven is automated. This effectively solves the inconvenience and labor-intensive problems caused by the traditional manual material feeding operation due to the enclosed and narrow structure of the hot drying oven with only openings at both ends, significantly improving the convenience and efficiency of initial material feeding and reducing operational difficulty and labor intensity.

[0008] Optionally, the conveying device further includes a locking structure. The conveying component includes a base and a cover movably disposed on the base. The locking structure is used to fix the cover relative to the base. The cover and the base are used to clamp and fix the woven fabric.

[0009] By adopting the above technical solution, and by setting up a conveyor component including a base and a cover, as well as a locking structure, a specific and reliable clamping and fixing method is provided. The cover and base work together to firmly clamp the woven fabric, ensuring that the woven fabric will not loosen during conveying; the locking structure can stably fix the cover to the base, maintain the clamping state, ensure the stability and reliability of the conveying, prevent material feeding failure or material damage due to clamping failure, and can also release the locking structure to allow the cover to detach from the woven fabric, so that the woven fabric and inner film can be removed from the conveyor component.

[0010] Optionally, the locking structure includes a locking block and a locking groove through which the locking block is inserted. The locking block is slidably disposed on the base in a direction perpendicular to the vertical direction and perpendicular to the extension direction of the hot oven. A locking elastic element is connected between the locking block and the base to allow the locking block to be inserted into the locking groove. The locking groove is formed through the cover.

[0011] By adopting the above technical solution, a simple and reliable self-locking mechanism is provided. The locking elastic element automatically drives the lock block into the lock groove to achieve locking, resulting in a simple and compact structure. The lock block is slidably set in a specific direction, making its operation stable and reliable, and not easily disturbed by forces in other directions. This ensures the stability of the clamping and the controllability of the operation, improving the durability of the equipment and the user experience. Furthermore, the lock groove penetrates through the cover, facilitating the unlocking of the cover and base. Unlocking can be achieved simply by pressing the lock block to disengage it from the lock groove.

[0012] Optionally, the locking block has an inclined pushing surface. When the cover moves to clamp the woven fabric, the cover can slide against the pushing surface, pushing the locking block to slide in the opposite direction to the direction in which the locking block is inserted into the locking groove.

[0013] By adopting the above technical solution, when the cover needs to be closed (to clamp the woven fabric), the cover will naturally slide and abut against the pushing inclined surface during its movement. The inclined surface guides the locking block in the direction of exiting the locking groove until the cover moves to the point where the locking groove aligns with the locking block. The locking block then inserts into the locking groove under the action of the locking elastic element, thus achieving automatic locking. This further simplifies the locking operation, eliminating the need for additional manual operation of the locking block and improving the convenience and efficiency of the equipment.

[0014] Optionally, a reset elastic element is connected between the cover and the base to allow the cover to move to the point of disengaging from the woven fabric. The base is provided with a limiting element, which abuts against the cover after the cover moves to the point of disengaging from the woven fabric.

[0015] By adopting the above technical solution, firstly, the reset elastic element can automatically spring the cover open to the position where it is detached from the clamped woven fabric, making it convenient for users to quickly insert or remove the woven fabric without manually opening the cover, thus improving the ease of operation; secondly, the setting of the limiting element restricts the range in which the cover is springed open, preventing the cover from being over-opened and causing damage or affecting operation, ensuring that the cover is always in a controllable and easy-to-operate position, thereby enhancing the reliability and safety of the equipment.

[0016] Optionally, it also includes a front conveyor roller group and a rear conveyor roller group. The front conveyor roller group, the hot drying oven, and the rear conveyor roller group are arranged along the extension direction of the hot drying oven. The front conveyor roller group and the rear conveyor roller group each include a rotation drive source, a driving wheel, and a driven wheel. The rotation drive source is used to drive the driving wheel to rotate. The driving wheel and the driven wheel are used to clamp and convey the woven fabric. A handwheel is detachably connected to the driven wheel.

[0017] By adopting the above technical solution, firstly, the front and rear conveyor roller groups provide stable and continuous conveying power for the woven fabric before and after the hot drying oven, realizing smooth conveying of the entire production line (initial feeding and subsequent continuous production); secondly, the detachable connection design of the handwheel on the driven wheel allows the woven fabric and inner film to be smoothly passed through the front and rear conveyor roller groups by turning the handwheel during the initial feeding, facilitating feeding; furthermore, in debugging or emergency situations, the driven wheel can be easily turned manually for precise position adjustment or manual pulling of the woven fabric, enhancing the operational flexibility and emergency handling capability of the equipment.

[0018] Optionally, it also includes a support cylinder located between the front conveyor roller group and the hot drying oven. The support cylinder extends along the extension direction of the hot drying oven, and both axial ends of the support cylinder are open and have an inner cavity.

[0019] By adopting the above technical solution, the support cylinder provides a stable and continuous support transition channel for the woven fabric before the inlet of the hot drying oven, avoiding problems such as jamming, wrinkling or even tearing of the woven fabric due to suspension, sagging or displacement at the inlet of the hot drying oven, which significantly improves the stability and smoothness of the conveying; and the support cylinder can control the expansion size of the inner cavity of the inner membrane, ensuring the composite quality.

[0020] Optionally, the conveying component extends along the extension direction of the support cylinder, and the length of the conveying component is greater than the distance between the hot oven and the support cylinder.

[0021] By adopting the above technical solution, it is ensured that when the conveyor transitions from the inner cavity of the support cylinder to the inner cavity of the hot drying oven, the head end of the conveyor has already entered the inner cavity of the hot drying oven before the end of the conveyor leaves the inner cavity of the support cylinder. This size design enables the conveyor to achieve seamless connection and conveying from the hot drying oven to the support cylinder, smoothly bringing the woven fabric from the support cylinder into the hot drying oven, avoiding the risk of the woven fabric loosening, jamming, or positional displacement at the gap between the two, further improving the success rate and reliability of the first feeding; it also eliminates the need for manual movement of the conveyor from the end of the support cylinder to the beginning of the hot drying oven, realizing the automation of the first feeding.

[0022] Optionally, it also includes two guide rods that can slide vertically. The two guide rods are arranged in a direction perpendicular to the vertical direction and perpendicular to the extension direction of the support cylinder. The guide rods extend along the extension direction of the support cylinder. Two guide holes communicating with the inner cavity of the support cylinder are opened on the circumferential side wall of the support cylinder. The guide holes correspond one-to-one with the guide rods and allow the guide rods to be inserted. The guide rods can pass through the guide holes and extend into the inner cavity of the support cylinder.

[0023] By adopting the above technical solution, since the circumferential sidewalls of the hot drying oven must be sealed, it is impossible to open guide holes on the hot drying oven to guide the conveying components. By inserting two guide rods into the guide holes of the support cylinder and extending them into its inner cavity, a temporary guide channel composed of two guide rods can be formed inside the support cylinder. This channel can effectively guide and constrain the position of the conveying components within the support cylinder, preventing them from deviating and sliding around the circumferential inner wall of the support cylinder. This allows the conveying components to continue moving in the same direction after they have moved into the hot drying oven, improving the sliding stability of the conveying components.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. It realizes the automated conveying of the woven fabric and inner film during the initial insertion into the hot drying oven, which significantly improves the convenience and efficiency of the initial material insertion of the equipment and reduces the difficulty of operation and labor intensity; 2. The locking elastic element can automatically drive the lock block to insert into the lock groove to achieve locking. The structure is simple and compact, easy to operate, and self-locking is reliable. 3. By inserting two guide rods into the guide holes of the support cylinder and extending them into its inner cavity, a temporary guide channel consisting of two guide rods can be formed inside the support cylinder to guide the sliding of the conveying component.

The conveying component 22 is detachably connected to the beginning of the woven fabric and the inner film.

[0037] Reference Figure 1 and Figure 3 The convenient internal adhesive film laminating machine also includes a front conveyor roller group 6 and a rear conveyor roller group 7, which are arranged along the conveying direction of the woven fabric. The front conveyor roller group 6 and the rear conveyor roller group 7 have the same structure. Both the front conveyor roller group 6 and the rear conveyor roller group 7 include a mounting frame 64, a rotation drive source 61, a driving wheel 62, and a driven wheel 63. The driving wheel 62 and the driven wheel 63 are rotatably mounted on the mounting frame 64, and their rotation axes extend in a direction perpendicular to the vertical direction and the extension direction of the heating box 1. The driving wheel 62 and the driven wheel 63 are arranged vertically and clamp and convey the woven fabric. The rotation drive source 61 is fixedly mounted on the mounting frame 64. The rotation drive source 61 is a drive motor, and its output shaft is fixedly connected to the driving wheel 62, thereby driving the driving wheel 62 to rotate.

[0038] Reference Figure 3 A handwheel 8 is detachably connected to the driven wheel 63 via a key and keyway, allowing the operator to rotate the driven wheel 63 by turning the handwheel 8. In other embodiments, the handwheel 8 may be omitted.

[0039] Reference Figure 1 The convenient internal adhesive film laminating machine also includes a support cylinder 9, which is located between the front conveying roller group 6 and the hot drying oven 1. The support cylinder 9 extends along the extension direction of the hot drying oven 1, and both axial ends of the support cylinder 9 are open and have an inner cavity. In other embodiments, the support cylinder 9 may not be provided.

[0040] Reference Figure 4The convenient internal adhesive film laminating machine also includes a lifting drive source 110 and guide rods 100. Two guide rods 100 are provided, arranged perpendicular to the vertical direction and the extension direction of the support cylinder 9. The lifting drive source 110 is an electric push rod, and its drive rod is fixedly connected to the two guide rods 100, thereby driving the two guide rods 100 to rise and fall synchronously.

[0041] Reference Figure 5 A guide hole 91 communicating with the inner cavity of the support cylinder 9 is provided on the lower surface of the circumferential side wall of the support cylinder 9. The guide hole 91 extends along the extension direction of the support cylinder 9. Two guide holes 91 are provided, each corresponding to a guide rod 100. The guide holes 91 allow the guide rod 100 to be inserted and pass through. The guide rod 100 can be raised to pass through the guide hole 91 and extend into the inner cavity of the support cylinder 9, thereby guiding the sliding of the conveyor 22.

[0042] Reference Figure 6 The conveying component 22 extends along the extension direction of the support cylinder 9. The length of the conveying component 22 is greater than the distance between the hot oven 1 and the support cylinder 9, so that the conveying component 22 can move smoothly from the inner cavity of the support cylinder 9 to the inner cavity of the hot oven 1.

[0043] Reference Figure 7 The conveying component 22 includes a base 221 and a cover 222, with the cover 222 rotatably mounted above the base 221. The cover 222 can rotate to fit against the base 221, thereby clamping and fixing the woven fabric. In other embodiments, the cover 222 can slide on the base 221 along the arrangement direction of the cover 222 and the base 221.

[0044] Reference Figure 7 and Figure 8 A reset elastic element 4, which is a torsion spring, is connected between the cover 222 and the base 221 to allow the cover 222 to rotate away from the base 221. The reset elastic element 4 is sleeved on the rotation axis of the cover 222. A limit element 5 is fixedly installed on the base 221. When the cover 222 rotates away from the base 221, the limit element 5 abuts against the cover 222, thereby limiting the rotation angle of the cover 222.

[0045] Reference Figure 7 and Figure 9The conveying device 2 also includes a locking structure 23, which can fix the cover 222 relatively to the base 221, so that the cover 222 is held in a clamping state on the woven fabric. The locking structure 23 includes a locking block 231 and a locking groove 232 through which the locking block 231 is inserted. The base 221 has a sliding groove 223 extending along the width direction of the base 221 on its surface in the width direction. The locking block 231 is slidably installed in the sliding groove 223 along the width direction of the base 221. A locking elastic member 3 is connected between the locking block 231 and the bottom wall of the sliding groove 223. The locking elastic member 3 is a compression spring, which is used to push the locking block 231 to slide to the end, exit the sliding groove 223, and insert into the locking groove 232. The locking groove 232 is formed through the cover 222.

[0046] Reference Figure 7 and Figure 9 On the upper surface of the end of the locking block 231 away from the bottom wall of the slide groove 223, an inclined pushing surface 233 is formed by a chamfering process. The distance between the pushing surface 233 and the bottom wall of the slide groove 223 increases vertically downward. When the cover 222 rotates toward the base 221, the cover 222 slides against the pushing surface 233, pressing the locking block 231 back into the locking groove 232.

[0047] Reference Figure 2 and Figure 4 Multiple sets of rollers 120 are rotatably mounted on the lower surface of the base 221, with each set of rollers 120 arranged along the length of the base 221. Each set has two rollers 120, which are arranged along the width of the base 221. The two rollers 120 are located between two guide rods 100, which guide and limit the rollers 120. The conveying drive source 21 is a drive motor, and the output shaft of the conveying drive source 21 is fixedly connected to one of the rollers 120, thereby driving the roller 120 to rotate.

[0048] The implementation principle of the convenient conveying inner film laminating machine of this application embodiment is as follows: First, place the beginning ends of the woven fabric and the inner film between the driving wheel 62 and the driven wheel 63 of the front conveying roller group 6, and rotate the handwheel 8 so that the beginning ends of the woven fabric and the inner film can pass smoothly through the driving wheel 62 and the driven wheel 63. Then, place the woven fabric and the inner film on the upper surface of the base 221, and rotate the cover 222 so that the cover 222 clamps the woven fabric and the inner film on the base 221. The locking block 231 is inserted into the locking groove 232 to fix the cover 222. Then, start the conveying drive source 21 to drive the conveying component 22 to move along the extension direction of the support cylinder 9 until the conveying component 22 moves the beginning ends of the woven fabric and the inner film to the outlet of the hot drying oven 1. Unlock the cover 222, remove the woven fabric and the inner film, and finally, in the same way as in the front conveying roller group 6, pass the beginning ends of the woven fabric and the inner film through the rear conveying roller group 7 to complete the first conveying of the woven fabric and the inner film.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
