Description

Technical Field

[0001] This utility model relates to the field of sealing strip glue injection technology, specifically to a glue injection equipment edge fitting device and the glue injection equipment. Background Technology

[0002] In the existing process of applying glue to luggage seals, the luggage seals need to be fitted onto all the conveyor rollers. By rotating and conveying the luggage seals, the seals are pressed together after being injected with glue by the glue injection machine. This process continues until the entire luggage seal is joined together after one full rotation.

[0003] Because the existing luggage sealing strips cannot adjust the conveyor rollers on both sides during the sealing process, they cannot be adapted to different sizes of luggage sealing strips for sealing, resulting in poor versatility of the existing glue injection equipment. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing glue injection equipment cannot adapt to different sizes of luggage sealing strips during the edge-joining process, resulting in poor versatility. To overcome the above-mentioned defects of the prior art, this invention provides a method that can also adapt to the width of luggage sealing strips of different sizes by using an edge-joining fixed guide wheel assembly and an edge-joining adjustable guide wheel assembly, greatly improving the versatility of the equipment.

[0005] To achieve the purpose of this utility model, the following technical solution is adopted:

[0006] A glue-applying device for edge joining includes a frame and a glue-applying edge joining mechanism mounted on the frame. The glue-applying edge joining mechanism includes an edge joining bracket, an edge joining fixed guide wheel assembly, an edge joining adjustable guide wheel assembly, and a glue-applying component. The edge joining bracket is mounted on the frame, the edge joining fixed guide wheel assembly is fixedly mounted on the edge joining bracket, and the edge joining adjustable guide wheel assembly is movably connected to the edge joining bracket. The edge joining fixed guide wheel assembly and the edge joining adjustable guide wheel assembly are distributed at a front-to-back interval, forming an edge joining channel for joining luggage sealing strips. The glue-applying component is flexibly connected to the frame and located above the edge joining channel, and is used to apply glue during edge joining. This device, through the front-to-back adjustable edge joining guide wheel assembly, can change the width of the edge joining channel, thereby better adapting to the edge joining of luggage sealing strips of different sizes, ensuring better edge joining effect and quality.

[0007] Preferably, the edge-fixing guide wheel assembly includes several horizontally arranged and spaced-apart edge-fixing guide wheels; the edge-adjusting guide wheel assembly includes several horizontally arranged and spaced-apart edge-adjusting guide wheels; each edge-adjusting guide wheel has a connecting seat at its bottom; and the connecting seat is movably connected to the edge-fitting bracket. The adjustable edge-fitting guide wheels allow for adjustment of the edge-fitting channel, thus adapting to different sizes of luggage sealing strips.

[0008] Preferably, the connecting seat is U-shaped with its opening facing downwards, and the edge-fitting adjusting guide wheel is rotatably connected to the top of the intermediate plate. The edge-fitting bracket has several adjusting through holes arranged at intervals in a front-to-back direction. The two side plates of each connecting seat are inserted into two corresponding adjusting through holes, and all the side plates of the connecting seats inserted into the adjusting through holes are connected together by an adjusting plate. An adjusting drive component is provided inside the edge-fitting bracket. The fixing part of the adjusting drive component is fixedly connected to the inner wall of the edge-fitting bracket, and the driving part of the adjusting drive component is connected to the adjusting plate, thereby driving the edge-fitting adjusting guide wheel on the adjusting plate to move back and forth for positioning.

The combination of the second edge-fitting limiting groove and the first edge-fitting limiting groove facilitates better matching with the luggage compartment sealing strip, thereby further improving the edge-fitting effect and quality.

[0011] Preferably, the feeding end of the edge-joining bracket is rotatably connected to a feeding auxiliary guide wheel via a feeding bracket; the discharging end of the edge-joining bracket is rotatably connected to a discharging auxiliary guide wheel via a discharging bracket. The feeding and discharging auxiliary guide wheels further ensure the flatness and stability of the luggage compartment sealing strip during edge joining, preventing the luggage compartment sealing strip from deviating from the conveying trajectory during edge joining.

[0012] Preferably, the glue injection assembly includes a glue injection bracket, an injection drive, and a glue injection machine. The glue injection bracket is vertically connected to the frame via the injection drive, and the glue injection machine is connected to the glue injection bracket, with the glue injection head at the bottom of the machine positioned above the edge-joining channel.

The clamping drive, in the form of a cylinder, drives the clamping guide wheel on the clamping connecting plate to press against the conveyed luggage sealing strip, applying a certain pressure to the luggage sealing strip to ensure stability during conveying and prevent the luggage sealing strip from lifting or detaching from the edge-joining channel at the discharge end, further ensuring the edge-joining effect and stability.

[0014] An adhesive injection device includes the aforementioned adhesive injection device edge-joining device.

[0015] In summary, the advantages of this utility model are that the adjustable edge-fitting guide wheel assembly can change the width of the edge-fitting channel, thereby better adapting to different sizes of luggage sealing strips for edge-fitting, ensuring better edge-fitting effect and quality. Furthermore, the pressure drive component, in the form of a cylinder, drives the pressure guide wheel on the pressure connecting plate to press against the luggage sealing strip being conveyed, giving the luggage sealing strip a certain pressure to ensure stability during the conveying process, and also preventing the luggage sealing strip from lifting or detaching from the edge-fitting channel at the discharge end, further ensuring the edge-fitting effect and stability.

[0025] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 4As shown, an adhesive injection device includes an edge-joining device, which includes a frame and an adhesive injection edge-joining mechanism 2. The adhesive injection edge-joining mechanism 2 includes an edge-joining bracket 20, an edge-joining fixed guide wheel assembly, an edge-joining adjustable guide wheel assembly, and an adhesive injection component 23. The edge-joining bracket 20 is mounted on the frame, and the platform of the edge-joining bracket 20 is horizontal. The edge-joining fixed guide wheel assembly is fixedly mounted on the edge-joining bracket 20, and the edge-joining adjustable guide wheel assembly is movably connected to the edge-joining bracket 20. The edge-joining fixed guide wheel assembly and the edge-joining adjustable guide wheel assembly are distributed at intervals, and an edge-joining channel 24 is formed between the edge-joining fixed guide wheel assembly and the edge-joining adjustable guide wheel assembly for pressing the luggage compartment sealing strip to join the edges. The adhesive injection component 23 is flexibly connected to the frame and located above the edge-joining channel 24. The adhesive injection component 23 is used to inject adhesive during edge joining. The device can change the width of the sealing channel 24 by using a front-to-back adjustable sealing guide wheel assembly, thereby better adapting to different sizes of luggage sealing strips for sealing, ensuring better sealing effect and sealing quality.

[0027] like Figure 2 and Figure 3 As shown, the edge-locking guide wheel assembly includes several horizontally arranged and spaced-apart edge-locking guide wheels 21. Each edge-locking guide wheel 21 has a first annular edge-locking limiting groove 210 on its outer peripheral wall. The first edge-locking limiting groove 210 facilitates better matching with the luggage compartment sealing strip, thereby further improving the edge-locking effect and quality. The edge-locking adjusting guide wheel assembly includes several horizontally arranged and spaced-apart edge-locking adjusting guide wheels 22. The outer peripheral wall of each edge-locking adjusting guide wheel 22 has a second edge-locking limiting groove 220 that cooperates with the first edge-locking limiting groove 210. The cooperation between the second edge-locking limiting groove 220 and the first edge-locking limiting groove 210 facilitates better matching with the luggage compartment sealing strip, thereby further improving the edge-locking effect and quality. Each edge-locking adjusting guide wheel 22 has a connecting seat 221 at its bottom; and the connecting seat 221 is movably connected to the edge-locking bracket 20. The adjustable edge guide rollers 22 allow for adjustment of the edge channel 24, thus adapting to different sizes of luggage sealing strips.

[0028] like Figure 3As shown, in this embodiment, the connecting seat 221 is U-shaped and the opening is facing downwards. The side adjustment guide wheel 22 is rotatably connected to the top of the middle plate. Several adjustment through holes 201 are arranged at intervals in the front-to-back direction on the side support 20. The two side plates of each connecting seat 221 are inserted into the two adjustment through holes 201 respectively, and all the side plates of the connecting seats 221 inserted into the adjustment through holes 201 are connected together by the adjustment plate 222. An adjustment drive is provided in the side support 20. The adjustment drive can be driven by a cylinder to move horizontally, or it can be driven by a hydraulic cylinder or an electric cylinder. The fixing part of the adjusting drive component is fixedly connected to the inner wall of the edge-closing bracket 20, and the driving part of the adjusting drive component is connected to the adjusting plate 222, thereby driving the edge-closing adjusting guide wheel 22 on the adjusting plate 222 to move back and forth for positioning. The feeding end of the edge-closing bracket 20 is rotatably connected to the feeding auxiliary guide wheel 203 through the feeding bracket 202. The discharging end of the edge-closing bracket 20 is rotatably connected to the discharging auxiliary guide wheel 205 through the discharging bracket 204. The feeding auxiliary guide wheel 203 and the discharging auxiliary guide wheel 205 further ensure the flatness and stability of the luggage compartment sealing strip when closing the edge, preventing the luggage compartment sealing strip from deviating from the conveying trajectory when closing the edge.

[0029] like Figure 1 and Figure 4 As shown, the glue injection assembly 23 includes a glue injection bracket 231, an injection driving component 232, and a glue injection machine 233. The glue injection bracket 231 is vertically connected to the frame via the injection driving component 232. The glue injection machine 233 is connected to the glue injection bracket 231, and the glue injection head 234 at the bottom of the glue injection machine 233 is located above the edge-joining channel 24. The injection driving component 232 drives the glue injection machine 233 to move up and down for positioning, thereby adjusting the glue injection head 234 on the glue injection machine 233 to the optimal glue injection position, thus ensuring the glue injection effect and stability in the actual production process.

[0030] like Figure 4As shown, the glue injection and edge-joining mechanism 2 also includes a sealing strip pressing assembly 25; the sealing strip pressing assembly 25 includes a pressing drive 251, a pressing connecting plate 252 and at least one pressing guide wheel 253, which in this embodiment are two pressing guide wheels 253; the pressing drive 251 is vertically connected to the frame through a pressing bracket 254, the pressing connecting plate 252 is connected to the bottom of the pressing drive 251 and the pressing drive 251 realizes the lifting and lowering of the pressing connecting plate 252, the pressing guide wheel 253 is rotatably connected to the pressing connecting plate 252, the two pressing guide wheels 253 are arranged laterally at intervals, and the pressing guide wheels 253 are located above the edge-joining channel 24. The pressing drive component 251, in the form of a cylinder, drives the pressing guide wheel 253 on the pressing connecting plate 252 to press against the luggage sealing strip being conveyed, giving the luggage sealing strip a certain pressure to ensure stability during the conveying process, and also preventing the luggage sealing strip from lifting up or detaching from the edge-joining channel 24 at the discharge end, further ensuring the edge-joining effect and edge-joining stability.

[0031] During operation, the luggage sealing strip is fitted onto the rotary drive mechanism of the glue-dispensing equipment, while simultaneously positioning the luggage sealing strip within the edge-joining channel 24. The width of the edge-joining channel 24 is adjusted by the adjusting plate 222 driven by the adjusting drive component. After the edge-joining adjusting guide wheel 22 is adjusted, it ensures that the edge-joining channel 24 matches the luggage sealing strip. The pressing drive component 251 on the sealing strip pressing assembly 25 drives the two pressing guide wheels 253 to press down on the luggage sealing strip, applying a certain force to it. This ensures stable transport of the luggage sealing strip while preventing it from detaching from the edge-joining channel 24. After the luggage sealing strip is tensioned and fitted, the synchronous belt is driven to rotate by a rotary drive mechanism in the form of a drive motor and a synchronous belt. The friction between the synchronous belt and the luggage sealing strip is used to rotate and transport the luggage sealing strip. During transport, under the pressure of the edge fixing guide wheel 21 and the edge adjusting guide wheel 22, glue is injected into the gap of the luggage sealing strip by the glue injection machine 233 to achieve edge sealing of the luggage sealing strip. Finally, the entire luggage sealing strip is glued and sealed by going around it once. After glue injection, the luggage sealing strip is removed, and the above actions are repeated for the next luggage sealing strip to be glued and sealed.

[0032] The advantage of this invention is that the width of the edge-fitting channel 24 can be changed by the adjustable edge-fitting guide wheel assembly, thereby better adapting to different sizes of luggage sealing strips for edge-fitting, ensuring better edge-fitting effect and quality. Furthermore, the pressing drive component 251 drives the pressing guide wheel 253 on the pressing connecting plate 252 in the form of a cylinder to press against the luggage sealing strip being conveyed, giving the luggage sealing strip a certain pressure to ensure stability during the conveying process, and also preventing the luggage sealing strip from lifting or detaching from the edge-fitting channel 24 at the discharge end, further ensuring the edge-fitting effect and stability.
