Description

Technical Field

[0001] The utility model relates to the technical field of improvement of tobacco processing equipment packaging machines, in particular to a strip box hot melt adhesive spraying device specially used for a C800-BV packaging machine. Background Art

[0002] In the past, ordinary cold glue could meet the bonding requirements of cigarette boxes and strip packaging. The original cold glue spraying system had problems such as uneven glue spraying and glue point loss, which may be due to the following reasons:

[0003] 1. The viscosity of cold glue is greatly affected by the environment: The viscosity of cold glue is easily affected by environmental factors such as temperature and humidity, resulting in unstable fluidity under different conditions, thus affecting the uniformity and accuracy of glue spraying.

[0004] 2. Cold glue takes a long time to cure: Compared with the quick curing characteristics of hot melt adhesive, cold glue takes longer to cure. During this period, if the product moves or the production line speed is fast, it is easy to cause the glue points to be misplaced or lost.

[0005] 3. Precision limitations of cold glue injection systems: Traditional cold glue injection systems may rely on simple mechanical or pneumatic controls, which may not be as accurate as modern electronic control systems, such as hot melt glue systems controlled by PLCs and amplifiers.

[0006] Nowadays, with the application of high-speed packaging machines and the continuous introduction of new packaging materials, packaging adhesives with faster bonding and stronger adhesion are needed. Compared with water-based adhesives, hot melt adhesives have become the first choice for some high-speed packaging machines and some materials that are difficult to bond because of their fast bonding speed and adaptability to bonding of materials that are not easily penetrated. Summary of the invention

[0007] In order to solve the above-mentioned deficiencies and defects in the prior art, the inventor has designed and tested a stably operating hot melt glue spraying device for strip boxes. The device has the characteristics of scientific and reasonable structure, convenient assembly, stable operation, and the ability to fine-tune the spray gun position, and realizes the function of applying hot melt glue to the strip box paper on the C800-BV packaging machine. Specifically, the utility model is implemented as follows:

[0008] The basic structure of a stably operated strip box hot melt adhesive spraying device consists of:

[0009] Install the side panel: It consists of the left side panel and the right side panel, and is responsible for fixing it on the gluing station of the packaging machine from the outer side;

[0010] Bottom plate: installed between the inner sides of the left and right side plates, arranged horizontally, used as a mounting platform for the spray gun bracket; Left connecting seat and right connecting seat: provide stable lateral fixation to ensure the stability of the entire device.

[0011] Spray gun bracket: installed horizontally on the bottom plate, carrying and installing multiple spray guns and branch pipelines to ensure the distribution and supply of branch pipelines of hot melt adhesive;

[0012] Spray gun: Arranged in a specific layout, the nozzles can directly act on different bonding areas of the box paper, including the left ear of the box, the left and right points of the bonding edge of the box, and the right ear of the box.

[0013] Auxiliary functions - adjustment and positioning:

[0014] Rotating chassis and card slot design: The rotating chassis at the bottom of the spray gun allows the spray gun to be fine-tuned by deflecting left and right along the center axis along the card slot, which is convenient for accurately adjusting the glue spraying position without affecting the stable docking and glue supply between the glue hose and the glue outlet hole.

[0015] Deflection dial and reading rod: The design of the reading rod makes it easy to record and reproduce the deflection angle of the spray gun, thereby improving the repeatability and efficiency of the operation.

[0016] Bracket baffle: Isolate the hot melt glue gluing device from the carton paper conveying channel. Only grooves are made on the baffle to allow the glue to be accurately applied to the gluing points of the carton paper, which can prevent glue from being sprayed accidentally on other non-gluing areas.

[0017] Layout and spraying mode:

[0018] Spray gun layout: The four spray guns are spaced 85mm, 165mm and 85mm apart to achieve precise spraying of the sides and long sides of the strip box.

[0019] Spraying mode: The 1st and 4th spray guns spray the sides multiple times, while the 2nd and 3rd spray guns spray the two ends of the long side once respectively to meet different bonding requirements.

[0020] Auxiliary safety measures:

[0021] Spray gun cover: protects the spray gun and surrounding parts while leaving necessary openings to avoid obstruction of operation.

[0022] Heat insulation board: isolates heat sources to prevent heat from being transferred to the cigarette package conveying channel, ensuring the safety of equipment and products.

[0023] Air pipe interface: Use compressed air to stabilize the output of glue liquid, ensure the smoothness of glue spraying and controllable glue output accuracy, so as to improve the quality of glue spraying.

[0024] The beneficial technical effects of the utility model are as follows: the hot melt glue spraying device for strip boxes of the utility model has a reasonable and simple structure. The hot melt glue spraying system structure is integrated within the original design space, and the space occupied is no more than the original cold glue spraying system. After installation, it will not interfere with the normal operation of the equipment; the glue spraying position of the spray gun meets the basic requirements of strip box packaging, and can avoid the occurrence of strip box debonding and the like; the high-temperature heating of the hot melt glue spraying will be isolated by the insulation board, which has burn protection and will not affect the quality of the cigarette packs; the accurate spraying of glue is achieved through the adjustable spray gun installation design, and the overall structure is convenient for disassembly, assembly and maintenance, realizing an efficient, accurate and safe hot melt glue spraying process, which is particularly suitable for the automated production line of the C800-BV packaging machine, and effectively improves the quality and efficiency of strip box packaging.

[0044] The spray gun bracket 4 is horizontally mounted on the bottom plate 3, and is used to mount a plurality of spray guns 5, and has a plurality of branch pipelines built therein, and the branch pipelines are used to connect with each spray gun 5; the branch pipelines are connected to the glue inlet 41, and the glue inlet 41 is used to connect with the rubber hose 42 to provide hot melt adhesive supply and delivery, and the hot melt adhesive is sprayed from the nozzle of the spray gun 5. The spray gun bracket 4 is designed to be 385mm long, 65.5mm wide, and 79mm high. The spray gun 5 on the original cold glue spray system spray gun bracket 4 can be rotated for easy cleaning, and the hot melt glue spray system spray gun 5 is relatively clean and does not require frequent maintenance;

[0045] The left side plate 1 and the right side plate 2 are fixed in cooperation with the original equipment station, thereby fixing the entire glue spraying device, so that the entire hot melt glue spraying assembly can complete the glue spraying work well without interfering with the equipment operation and causing major modifications to the equipment structure.

[0046] Preferably, the spray guns 5 are installed on the spray gun bracket 4 in a horizontally parallel arrangement in sequence, and the positions of the spray guns 5 correspond to several areas of the strip box paper 6 passed through, and the areas at least include: the left bonding ear, the left point of the strip box bonding edge, the right point of the strip box bonding edge, and the right bonding ear of the strip box.

[0047] Preferably, a circular arc-shaped rotating chassis 51 is provided at the bottom of the spray gun 5, and a spray gun mounting seat 52 is also installed on the spray gun bracket 4. The spray gun mounting seat 52 is provided with four semi-circular arc-shaped slots 53, and the edges of the slots 53 are provided with arc edges that are compatible with the rotating chassis 51. The flange of the rotating chassis 51 can be inserted into the arc edges, so that the spray gun 5 can deflect left and right along the center of the arc edges. The center of the rotating chassis 51 is provided with a glue outlet hole 55 opened at the center of the arc edges, and the rubber hose 42 can be connected and inserted into the branch pipeline for glue supply.

[0048] Preferably, a deflection dial 56 is installed on the spray gun bracket 4 just in front of each spray gun 5 , so that after the spray gun 5 is installed, the nozzle can be placed above the deflection dial 56 .

[0049] Preferably, a left connecting seat 43 and a right connecting seat 44 are installed on both ends of the bottom plate 3, and are installed and fixed to the left side plate 1 and the right side plate 2 by bolts passing through the left connecting seat 43 and the right connecting seat 44.

[0050] Preferably, a support baffle 7 is further included, which is longitudinally installed between the spray gun support 4 and the strip box conveying channel to isolate the hot melt glue spraying from the strip box paper 6. A slot 71 is opened on the plate surface of the support baffle 7 at the position corresponding to the nozzle of each spray gun 5, and the hot melt glue can be applied to the strip box paper 6 passing below in the slot 71. The slot 71 is designed to be 10 mm wide, so that the hot melt glue can be sprayed smoothly on the strip box surface.

[0051] Preferably, the spray guns 5 are arranged on the same plane, and spraying at different positions on the strip box packaging paper is achieved by adjusting the spray gun 5 instructions. There are four spray guns 5, which are arranged from left to right in sequence, with an interval of 85mm / 165mm / 85mm. The first and fourth spray guns 5 are actually aimed at the glue points on the side of the strip box for 6 times each, and the second and third spray guns 5 are used to spray once at each end of the long side of the strip box. The arrangement of the spray guns 5 is not limited to the above description. According to the process requirements of the strip box packaging, the number of spray guns 5 can be appropriately adjusted to change the number of longitudinal glue point groups in the direction of movement of the strip box, and the number of times each spray gun 5 sprays glue on each strip box packaging paper can also be adjusted to change the number of glue points in the same longitudinal direction.

[0052] Preferably, it also includes: a spray gun cover 8, which is used to cover the spray gun bracket 4 from above the spray gun bracket 4, and the side of the spray gun cover 8 is provided with a plurality of slots corresponding to the nozzle of the spray gun 5 and the installation position of the hose 42. The spray gun cover 8 fixedly surrounds the entire spray gun bracket 4 to prevent dust from contaminating the spray gun 5, and at the same time prevent glue leakage to a certain extent to affect the operation of the equipment.

[0053] Preferably, a heat insulation board 9 is installed between the spray gun support 4 and the bottom plate 3 and fixed by bolts to prevent the high temperature of the spray gun 5 from being transmitted to the cigarette pack conveying channel below. The heat insulation board 9 can be replaced with different thicknesses according to needs and is a ceramic heat insulation material. In terms of structure, it can also be used as a way to adjust the relative height of the spray gun 5.

[0054] Preferably, the back of the spray gun bracket 4 is also provided with an air pipe interface 45 for connecting with an air pipe 46, which can apply air pressure to the hot melt adhesive in the hose 42 through compressed air, so as to enable the adhesive to be sprayed out from the nozzle stably, evenly and controllably.

[0055] In this embodiment, the hose 42 is used to connect to the hot melt adhesive cylinder, which stores and heats the hot melt adhesive to a liquid state, ensuring that the colloid is in a flow state suitable for spraying. The piston pump built into the adhesive cylinder is located inside the adhesive cylinder and is responsible for pumping the liquid hot melt adhesive to the hose 42, while maintaining a constant pressure of the adhesive liquid in the hose 42, ensuring the stability of the glue transmission and the consistency of the spraying. The hose 42 serves as a transmission channel for the hot melt adhesive, transporting the liquid glue from the adhesive cylinder and the piston pump to the spray gun 5 module. The entire process is precisely controlled by the PLC controller, ensuring timely and appropriate glue supply.

[0056] Example 2: Actual operation steps:

[0057] Installation device: First, the device is closely matched and fixed with the gluing station of the C800-BV packaging machine through the left side plate 1 and the right side plate 2, and the bottom plate 3 is located between the two side plates, serving as the support base of the entire glue spraying system. At the same time, the left connecting seat 43 and the right connecting seat 44 at both ends of the bottom plate 3 are connected to the two side plates by bolts to ensure that the entire device is stable and reliable.

[0058] Access to hot melt adhesive supply: connected to the hot melt adhesive cylinder through the rubber hose 42 and connected to the control system. The glue cylinder is responsible for storing and heating the hot melt adhesive to a liquid state, so that it maintains a fluid state suitable for spraying. The built-in piston pump continuously extracts the liquid hot melt adhesive from the glue cylinder and transports it to the branch pipeline on the spray gun bracket 4 through the rubber hose 42. This process is precisely controlled by the PLC controller to ensure timely and appropriate supply of glue.

[0059] Determine the layout and adjustment of the spray gun 5: Four spray guns 5 are installed on the spray gun bracket 4, and they are arranged horizontally, each corresponding to a specific bonding area on the strip paper 6, such as the left ear, the strip box bonding edge, etc., to determine whether the nozzle is in the specific corresponding bonding area, and determine through the dial whether the nozzle position is precisely arranged as required. The rotating chassis 51 at the bottom of each spray gun 5 allows the spray gun 5 to deflect left and right along the arc edge, which is convenient for precise alignment of the glue spraying position, and a deflection dial 56 and a reading rod are installed in front of each spray gun 5 to facilitate fine adjustment of the spraying angle and monitoring of the spraying position.

[0060] Precise spraying: Start the equipment and when the strip paper 6 passes through the glue spraying device, the hot melt glue is precisely sprayed to the set area through the nozzle of the spray gun 5. The bracket baffle 7 isolates the hot melt glue from the strip paper conveying channel, and the slot 71 on it allows the hot melt glue to act directly on the strip paper surface, ensuring the accuracy of the glue point and the neatness of the strip paper. The number and position of the glue spraying of the spray gun 5 can be flexibly changed by adjusting the spray gun 5 instructions to meet different packaging process requirements.

[0061] Safety and maintenance: The spray gun cover 8 covers the entire spray gun bracket 4 to prevent dust pollution and reduce the risk of glue overflow. The installation of the heat insulation board 9 effectively isolates the high temperature of the spray gun 5 from the impact of the cigarette pack conveying channel below, and also provides the function of height adjustment of the spray gun 5. The air pipe interface 45 applies compressed air to the hot melt glue in the hose 42 to ensure stable and uniform output of the glue. Although the hot melt glue system is cleaner than the cold glue system and reduces the need for frequent maintenance, if the spray gun 5 needs to be cleaned or maintained, the structure of the spray gun 5 is still designed to facilitate quick disassembly and cleaning.

[0062] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
