Description

Technical Field

[0001] The present application relates to the technical field of belt production, and in particular to a belt production line. Background Art

[0002] In modern fashion, suit pants are a common and classic style. The matching belt not only serves a practical function, tightening the waistband, but also often serves as a decorative element, showcasing personal style. To ensure belt quality and meet consumer demand for durability and aesthetics, many manufacturers generally adopt a double-layer construction when producing belts. This design, by combining two layers of belt, enhances the belt's strength and toughness, making it less susceptible to deformation and breakage during daily use. Due to their excellent quality, double-layer belts are widely popular in the market and a popular choice among consumers.

[0003] The bonding process is crucial in the production of double-layer belts. Currently, manufacturers generally use glue to secure the two layers together. During this process, workers first evenly apply glue to one side of each belt, ensuring the coating area and thickness meet the required requirements. After the glue is applied, another team of workers presses the two glued sides together. This process ensures the two layers are tightly bonded, forming a solid whole, thus ensuring the belt's quality and stability.

[0004] After the glue is applied, due to its fluidity, when the two belts are crimped together, the glue will flow in all directions under the pressure. This flow results in uneven glue distribution across the bonding surface. Excess glue in some areas may overflow, affecting the belt's appearance; while insufficient glue in others may result in insufficient bond strength, affecting the belt's service life. To address this issue, manufacturers typically leave the glue to stand for a period of time after application to allow the glue to initially cure and reduce flow. However, while this method facilitates bonding, it significantly increases production cycles and reduces overall processing efficiency, leaving significant room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a belt production line to solve the problem of low quality of the finished belt due to the fluidity of the glue during the crimping process after the two belt bodies are coated with glue in the above-mentioned related technology.

[0006] The belt production line provided in this application adopts the following technical solution: A belt production line comprises a glue injection station, a drying station and a crimping station arranged in sequence along a straight line direction, a glue injection assembly is provided above the glue injection station, and a crimping assembly is provided on the crimping station; a conveyor belt and a driving member for driving the conveyor belt are provided on the upper surface of the drying station, and the two ends of the conveyor belt are respectively close to the upper surface edges of the glue injection station and the crimping station; a receiving plate is provided above the drying station, and downwardly bent support plates are fixed on the opposite side surfaces of the receiving plate, and the lower sides of the two support plates are respectively fixed to the opposite upper edges of the drying station; the receiving plate, the support plate and the conveyor belt together constitute a drying chamber for the belt body to move into, and a drying member for heating is fixed on the side of the receiving plate close to the conveyor belt.

[0007] By adopting the above technical solution, after the glue coating is completed at the glue injection station, the belt body enters the drying station via the conveyor belt. The drying chamber above the drying station, which is composed of a receiving plate, a support plate and a conveyor belt, provides a relatively closed drying space for the belt body. The drying parts of the receiving plate close to the side of the conveyor belt can dry the glue on the belt body in time. This can quickly make the glue initially solidify, reduce the flow of glue during the subsequent crimping process, and avoid uneven glue distribution. Unlike the traditional static method, it will not significantly extend the production cycle and reduce processing efficiency. It can also ensure that the glue is evenly distributed on the bonding surface, preventing the appearance of the belt from being affected by excessive glue overflow in some areas, and insufficient bonding strength due to insufficient glue in some areas. It effectively improves the quality and stability of the finished belt and meets consumers' demand for belt durability and aesthetics.

[0008] Optionally, the upper surface of the glue injection platform is higher than the upper surface of the drying platform, and a guide plate is obliquely arranged above the drying platform; one side edge of the guide plate is detachably connected to the upper edge of the side of the glue injection platform close to the drying platform, and the other side edge is in contact with the upper side of the drying platform.

[0009] By adopting this technical solution, during the belt production process, the glue-injected belt body can slide easily and smoothly from the glue injection table to the drying table thanks to the tilted angle of the guide plate. This eliminates the need for complex conveyor devices or excessive manual intervention, streamlining the production process and improving production efficiency. Furthermore, the detachable connection allows for flexible adjustment of the guide plate's position or replacement and maintenance based on actual production needs, enhancing the equipment's versatility and maintainability.

[0010] Optionally, two vertically upward positioning rods are installed relatively on the upper side edge of the receiving plate close to the glue injection platform; two support arms arranged relatively to each other for supporting the glue injection assembly are fixed on the upper side edge of the glue injection platform; a protective curtain is provided above the drying platform, and a number of hooks are fixed on the opposite sides of the protective curtain, and snap rings for the hooks to be engaged are provided on the sides close to each other of the support arms and the upper parts of the positioning rods.

[0011] By adopting this technical solution, during the belt production process, the protective curtain effectively blocks dust and impurities from entering the area between the glue injection station and the drying station, preventing these contaminants from adhering to the glue-coated belt surface, ensuring effective adhesion and ultimately improving the quality of the finished belt. Furthermore, this detachable installation method allows for flexible adjustment of the curtain's installation based on actual production conditions, facilitating equipment maintenance and cleaning, as well as easy replacement of the curtain. This reduces production costs, improves production efficiency, and enhances equipment usability.

[0012] Optionally, an extrusion plate is provided on the upper opposite edges of the drying table, whose length direction is parallel to the sliding direction, and an elastic reset part is provided to drive the extrusion plate to slide away from the drying table, and an adjusting part is provided on the positioning rod to drive the extrusion plate to slide toward the drying table; the first plug-in block and the second plug-in block are rotatably connected to the opposite side surfaces of the guide plate respectively, and a first slot for inserting the first plug-in block is provided on the side of the glue injection table facing the drying table, and a second slot for inserting the second plug-in block is provided on the side of the extrusion plate close to the glue injection table; the second plug-in block can remain inserted into the second slot under the action of the adjusting part.

[0013] By adopting the above technical solution, during normal production, the adjustment member drives the extrusion plate closer to the drying table, so that the second plug remains inserted into the second slot, and the first plug is inserted into the first slot. This can firmly install the guide plate, ensuring that the strip slides smoothly from the injection station into the drying table, ensuring a smooth production process. When the equipment needs to be stored or adjusted, the adjustment member releases the pressure on the extrusion plate, and the elastic reset member drives the extrusion plate away from the drying table. The first and second plugs can easily be removed from the slots, facilitating the removal and storage of the guide plate. This design not only ensures the stability of the guide plate during production, but also improves the convenience of equipment storage and adjustment, optimizes the production space layout, and improves production efficiency and equipment flexibility.

[0014] Optionally, the elastic return member includes a first spring, a baffle fixed on the extrusion plate and a limit plate fixed on the upper surface of the drying table, the baffle and the limit plate are located on the sides relatively far away from the two extrusion plates, the baffle is located on the side of the limit plate away from the injection platform, and the two ends of the first spring are respectively fixedly connected to the sides of the baffle and the limit plate close to each other.

[0015] By adopting the above-mentioned technical solution, when the adjusting member drives the extrusion plate to move toward the drying table, the first spring is compressed, generating a reverse elastic force. When the extrusion plate needs to be released, the elastic force of the first spring can quickly drive the extrusion plate to slide and reset in the direction away from the drying table. The fast response speed can ensure that the extrusion plate returns to its initial position in time, facilitating the removal or subsequent operation of the guide plate. At the same time, the setting of the baffle and the limit plate plays a good role in positioning and protecting the first spring, preventing the first spring from being offset or damaged during the extension and retraction process, thereby ensuring the stability and reliability of the elastic reset member. Moreover, this structure has low cost, is easy to install and maintain, can effectively reduce production costs, improve production efficiency, and ensure the normal operation of the belt production line.

[0016] Optionally, the lower end of the positioning rod is rotatably connected to the vertical side of the support plate, and the adjusting member is an adjusting rod fixed on the outer periphery of the lower end of the positioning rod, the adjusting rod is perpendicular to the length direction of the positioning rod, and a limiting slot is provided on the side of the extrusion plate away from the guide plate; when the end of the adjusting rod rotates to a horizontal state in the direction close to the extrusion plate, it can squeeze the extrusion plate and be stuck into the limiting slot, and the positioning rod is in a vertical upward state and fixed in this state.

[0017] By adopting the above technical solution, when it is necessary to slide the extrusion plate toward the drying table, the adjustment rod at the lower end of the positioning rod is rotated to a horizontal state. The end of the adjusting rod can exert an extrusion effect on the extrusion plate and simultaneously engage the limit slot provided on the side of the extrusion plate away from the guide plate, thereby fixing the extrusion plate in a suitable position. At this time, the positioning rod is in a vertically upward state, providing stable support for the installation of the guide plate, ensuring that the guide plate is firmly connected to the injection table and the drying table, and ensuring the smooth transfer of the belt body. When it is necessary to remove the guide plate or adjust the equipment, it is only necessary to rotate the adjustment rod in the opposite direction to disengage it from the limit slot, and the extrusion plate can be reset under the action of the elastic reset member. This design is simple and convenient to operate, does not require complex tools and a large amount of manpower, greatly improves the efficiency of equipment adjustment, reduces the difficulty of operation, helps to quickly respond to changes in production needs, and improves the overall operating efficiency of the belt production line.

[0018] Optionally, after the first plug block is disengaged from the first slot, the guide plate can be rotated in the direction away from the injection molding table to be in a horizontal storage state between the two extrusion plates; the two extrusion plates are close to each other and a first notch is provided on the side surfaces for the first plug block to be rotated into when the guide plate is in the horizontal storage state; after the adjusting rod is disengaged from the limit slot, the positioning rod can be rotated in the direction close to the injection molding table to a horizontal folding state abutting against the side surfaces of the extrusion plates.

[0019] By adopting this technical solution, after the first insert is removed from the first slot, the guide plate can be rotated to be stored horizontally between the two extrusion plates, saving space. A first notch is provided on the side of the extrusion plate to accommodate the first insert, making storage more organized. After the adjustment rod is removed from the limit slot, the positioning rod can be rotated to a horizontal folded position that abuts the side of the extrusion plate, further reducing space usage and facilitating storage and organization of the device when not in use or when adjusting its layout, thereby improving space utilization.

[0020] Optionally, a connecting rod is provided above the drying table, and both ends of the connecting rod are respectively connected and fixed to the side surfaces of the two positioning rods that are close to each other.

[0021] By adopting the above technical solution, the connecting rod connects and fixes the sides of the two positioning rods that are close to each other, thereby enhancing the overall stability of the positioning rods. The positioning rods can better maintain their own state during operations such as adjusting the position of the extrusion plate and supporting the protective curtain, reducing shaking or offset, thereby ensuring that the guide plate is firmly installed and the extrusion plate slides smoothly, thereby improving the stability and reliability of the belt production line operation.

[0022] Optionally, both ends of the connecting rod are slidably connected to the positioning rod, and the connecting rod can slide back and forth along the length direction of the positioning rod, and a locking piece is provided on the outside of the positioning rod to fix the sliding state of the positioning rod; when the guide plate is in a horizontal storage state, a locking protrusion is fixed on the side away from the drying platform, and a locking notch is opened on the outer periphery of the connecting rod, and the connecting rod can slide until the locking protrusion is engaged in the locking notch.

[0023] By adopting this technical solution, when the guide plate and positioning rod are both in the horizontal storage position, the connecting rod can slide until the locking protrusion engages the locking notch, further securing the guide plate and preventing it from shaking, ensuring a stable storage state. This design also allows for flexible adjustment of the connecting rod position based on actual conditions, improving the flexibility of the device and the stability of its storage.

[0024] Optionally, a storage cavity for placing the protective curtain is opened on one side of the connecting rod, and a cover plate for sealing the storage cavity is detachably installed.

[0025] By adopting this technical solution, the connecting rod provides a storage cavity for the protective curtain. When the equipment is not in use or needs adjustment, the protective curtain can be stored inside, preventing damage or loss due to random placement, saving space and facilitating management. A removable cover effectively seals the storage cavity, preventing dust and other impurities from entering, keeping the protective curtain clean and intact. It also allows for quick access when needed, enhancing the convenience of equipment use.

[0026] In summary, this application has the following beneficial technical effects: After the glue is applied at the glue injection station, the strip passes through a conveyor belt and enters the drying station. A drying chamber above the drying station, consisting of a receiving plate, support plates, and conveyor belt, provides a relatively enclosed drying space for the strip. Drying elements on the receiving plate, located near the sides of the conveyor belt, allow for immediate drying of the glue on the strip. This ensures a rapid initial curing of the glue, minimizing glue flow during the subsequent crimping process and preventing uneven glue distribution. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Reference Figure 2 The crimping assembly 6 includes two crimping rollers 61 installed on the crimping table 3 and distributed up and down, and a driving source for driving the crimping rollers 61. The driving source is a conventional motor. A crimping gap is preset between the two crimping rollers 61 for the two strips to be placed and pressed. The specific structure is not repeated here. After the glue on the two belts is initially dried, the staff on one side of the crimping table 3 is arranged to press the sides of the two belts coated with glue toward each other, and then place the two belts that have been initially pressed together into the crimping gap. As the crimping roller 61 rotates, the two belts are fully pressed and fall onto the crimping table 3.

[0034] Reference Figure 2 The drying assembly 5 includes a receiving plate 51 located above the drying table 2, wherein downwardly bent support plates 52 are integrally formed on opposite sides of the receiving plate 51, and the lower sides of the two support plates 52 are respectively fixed to the two opposite upper edges of the drying table 2; A drying component 53 for heating is fixedly provided on the side of the receiving plate 51 close to the conveyor belt 21, wherein the drying component 53 is a heating tube 531 fixed on the receiving plate 51. The heating tube 531 is a conventional heating structure and will not be described in detail here. After the drying component 5 is installed, the receiving plate 51, the support plate 52 and the conveyor belt 21 together constitute a drying chamber 511 for the belt body to move into.

[0035] The implementation principle of the embodiment of this application is: After the belt body is coated with glue by the glue injection component 4 of the glue injection station 1, it slides into the conveyor belt 21 on the drying station 2. After being dried by the drying component 5, the staff presses the glue-coated surfaces of the belt body toward each other and places it in the gap between the crimping rollers 61 of the crimping station 3 to complete the production.

[0036] Example 2: Reference Figure 3 and Figure 4 The difference between the embodiment of the present application and embodiment 1 is that a protective component 7 is provided above the receiving plate 51, wherein the protective component 7 includes two positioning rods 72 installed relatively vertically upward on the edge of the upper side of the receiving plate 51 close to the glue injection platform 1; a protective curtain 71 of flexible material is provided above the drying platform 2, wherein two hooks 711 are fixed on the opposite sides of the protective curtain 71, and a snap ring 721 for the hook 711 to be engaged is provided on the side close to each other on the upper part of the support arm 11 and the positioning rod 72; in this way, the upper part between the glue injection platform 1 and the receiving plate 51 is sealed by the protective curtain 71, reducing the ingress of external dust or other impurities into the upper side of the belt body coated with glue.

[0037] Reference Figure 5 The upper surface of the glue injection platform 1 is higher than the upper surface of the drying platform 2, and a guide plate 8 is arranged obliquely above the drying platform 2; one side edge of the guide plate 8 is detachably connected to the upper edge of the side of the glue injection platform 1 close to the drying platform 2, and the other side edge is in contact with the upper side of the drying platform 2; it is convenient for the strip body that has been glued to slide from the upper edge of the glue injection platform 1 to the drying platform 2 along the guide plate 8.

[0038] Reference Figure 5 and Figure 6 A squeezing assembly 9 for adjusting the installation state of the guide plate 8 is provided above the drying table 2, wherein the squeezing assembly 9 includes two squeezing plates 91 slidably arranged on two opposite edges of the upper side of the drying table 2, and an elastic reset member 92 installed on the drying table 2 to drive the squeezing plates 91 to slide away from the drying table 2, wherein the length direction of the squeezing plates 91 is parallel to the sliding direction, and the positioning rod 72 is provided with an adjusting member 93 that drives the squeezing plates 91 to slide toward the drying table 2; The guide plate 8 is rotatably connected to the first plug-in block 81 and the second plug-in block 82 on the opposite sides thereof.

A second slot 911 for inserting the second plug-in block 82 is provided on the side of the extrusion plate 91 close to the glue injection station 1. When the positioning rod 72 rotates to the vertical upward state, the adjusting member 93 on the positioning rod 72 overcomes the elastic force of the elastic reset member 92 to squeeze the extrusion plate 91 toward the guide plate 8. At this time, the second plug block 82 can remain inserted into the second slot 911 under the action of the adjusting member 93.

[0039] Reference Figure 7The elastic return member 92 includes a first spring 921 in a compressed state, a baffle 922 fixed on the extrusion plate 91, and a limit plate 923 fixed on the upper surface of the drying table 2, wherein the baffle 922 and the limit plate 923 are located on the sides relatively far away from the two extrusion plates 91, and the baffle 922 is located on the side of the limit plate 923 away from the injection table 1. The two ends of the first spring 921 are respectively fixedly connected to the sides of the baffle 922 and the limit plate 923 close to each other.

[0040] Reference Figure 7 The lower end of the positioning rod 72 is rotatably connected to the vertical side of the support plate 52, wherein the adjustment member 93 is an adjustment rod 931 fixedly mounted on the outer periphery of the lower end of the positioning rod 72, and the adjustment rod 931 is perpendicular to the length direction of the positioning rod 72. A limiting slot 912 is provided on the side of the extrusion plate 91 away from the guide plate 8; When the adjusting rod 931 rotates to a horizontal state in the direction close to the extrusion plate 91, the end of the adjusting rod 931 can squeeze the extrusion plate 91 and be snapped into the limiting slot 912. At this time, the positioning rod 72 is in a vertical upward state and fixed, which not only realizes the limiting fixation of the vertical state of the positioning rod 72, but also realizes the extrusion plate 91, ensuring the installation stability of the guide plate 8.

At this time, the first plug 81 is rotated and inserted into the corresponding first notch 913; finally, the positioning rod 72 is rotated towards the injection station 1 to a horizontal folded state. The positioning rod 72 now abuts against the upper side of the extrusion plate 91; this arrangement allows the structure on the drying station 2 to be stored and folded, making it easier to pack and transport. There is a gap between the inner wall of the first notch 913 and the outer side of the first plug 81, so the two can be smoothly plugged in, and the plugging will not affect the subsequent rotation of the first plug 81. Reference Figure 11, guide sliders 731 are fixed at both ends of the connecting rod 73, and guide grooves 722 for the guide sliders 731 to be inserted and slide are opened on the sides of the two positioning rods 72 close to each other, thereby realizing the sliding connection between the connecting rod 73 and the positioning rod 72, and the connecting rod 73 can slide back and forth along the length direction of the positioning rod 72; A locking member 74 is provided on the outside of the positioning rod 72 to fix the sliding state of the positioning rod 72. A locking screw hole is provided on the guide slider 731. The positioning rod 72 is provided with a plurality of locking through holes that are connected to the guide slide groove 722 and can coincide with the locking through holes. The locking member 74 is a locking bolt 741 that passes through the locking through hole and is screwed into the locking screw hole. The locking bolt 741 is a butterfly bolt; it is convenient for adjusting and fixing the installation position of the connecting rod 73.

[0043] Reference Figure 12 On one side of the connecting rod 73 is a receiving cavity 733 for placing the protective curtain 71, and a cover plate 75 for blocking the receiving cavity 733 is detachably installed; one side of the cover plate 75 is rotatably connected to the opening edge of the receiving cavity 733, and the other side of the cover plate 75 is detachably fixed to the other side of the opening edge of the receiving cavity 733 by screws, so that the protective curtain 71 (see Figure 3 ) storage and use.

[0044] The implementation principle of the embodiment of this application is: The application process of the assembly line is divided into normal production mode and storage and transportation mode: In normal production mode, after the belt body is coated with glue by the glue injection assembly 4 of the glue injection station 1, it slides onto the conveyor belt 21 on the drying station 2 through the guide plate 8. After drying by the drying assembly 5, the staff presses the glue-coated surfaces of the belt body together and places it in the gap between the crimping rollers 61 of the crimping station 3 to complete the production. At the same time, the protective curtain 71 prevents dust and impurities from falling in. In the storage and transportation mode, by adjusting the positioning rod 72, the extrusion plate 91, the guide plate 8 and the connecting rod 73 and other structures, the guide plate 8 and the positioning rod 72 are folded and stored above the drying table 2, and the protective curtain 71 can be stored in the storage cavity 733 of the connecting rod 73, which is convenient for packaging and transportation.
