Description

Technical Field

[0001] This utility model relates to the field of sealing strip adhesive injection technology, and more specifically, to a luggage sealing strip adhesive injection device. 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 conveyor rollers on luggage sealing strips are fixedly mounted on the frame, they can only be used for gluing and edge-joining of luggage sealing strips of a single size. They cannot be used for gluing and edge-joining of luggage sealing strips of different sizes. As a result, when changing product sizes, it is necessary to switch to another gluing machine, which increases production costs. Furthermore, during the edge-joining process, the conveyor rollers on both sides of the edge-joining machine cannot be adjusted, making it impossible to adapt to different sizes of luggage sealing strips for edge-joining. This results in poor versatility of the existing gluing 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, resulting in poor versatility. To overcome the above-mentioned defects of the prior art, this invention provides a method to adjust the conveyor guide wheels through a horizontal adjustment component and a vertical adjustment component, which facilitates the adaptation to different sizes of luggage sealing strips. At the same time, the combination of the edge-fixing guide wheel assembly and the edge-adjusting guide wheel assembly can also adapt to the width of the edge of different sizes of luggage sealing strips, greatly improving the versatility of the equipment.

[0030] like Figures 1 to 8 As shown, a luggage sealing strip adhesive injection device includes a frame, a guide wheel tension adjustment mechanism 1, and an adhesive injection and edge-sealing mechanism 2. A vertical support panel 101 is provided on the front side of the frame. The guide wheel tension adjustment mechanism 1 includes a horizontal adjustment component 11, a vertical adjustment component 12, and a transmission drive component 13, all mounted on the frame. The horizontal adjustment component 11 includes a horizontal guide wheel 111, which is located on the front side of the support panel 101. Under the drive of the horizontal adjustment component 11, the horizontal guide wheel 111 moves laterally and is positioned laterally on the frame. The vertical adjustment component 12 includes a vertical guide wheel 121, which is located on the front side of the support panel 101. Under the drive of the vertical adjustment component 12, the vertical guide wheel 121 moves vertically and is positioned vertically on the frame. The luggage sealing strip is tensioned on the transmission drive assembly 13, the horizontal guide wheel 111, and the vertical guide wheel 121. The transmission drive assembly 13 drives the luggage sealing strip to rotate. The horizontal guide wheel 111 and the vertical guide wheel 121 can be adjusted to accommodate luggage sealing strips of different sizes, which also increases the flexibility of the equipment. The glue injection and edge-joining mechanism 2 includes an edge-joining bracket 20, an edge-joining fixed guide wheel group, an edge-joining adjusting guide wheel group, and a glue injection assembly 23. The edge-joining bracket 20 is set on the frame, and the platform of the edge-joining bracket 20 is set horizontally. The edge-joining fixed guide wheel group is fixedly set on the edge-joining bracket 20. The edge-joining adjusting guide wheel group is movably connected to the edge-joining bracket 20. The edge-joining fixed guide wheel group and the edge-joining adjusting guide wheel group are distributed at intervals, and an edge-joining channel 24 is formed between the edge-joining fixed guide wheel group and the edge-joining adjusting guide wheel group for pressing the luggage sealing strip to join the edges. The glue injection assembly 23 is lifted and connected to the frame and is located above the edge-joining channel 24. The glue injection assembly 23 is used to inject glue during edge joining. The device, through its horizontally adjustable lateral guide wheel 111 and vertically adjustable vertical guide wheel 121, can better adapt to luggage sealing strips of different sizes. It can also adjust the optimal tension of the luggage sealing strip during actual production, thereby achieving better conveying effect and conveying stability, and facilitating better edge-joining processing. The front-to-back adjustable edge-joining guide wheel group can change the width of the edge-joining channel 24, thereby better adapting to luggage sealing strips of different sizes for edge-joining, ensuring better edge-joining effect and quality.

[0031] like Figure 1 and Figure 2As shown, the lateral adjustment assembly 11 also includes a lateral drive component, a first guide wheel bracket 112, and a first connecting shaft 113. The support panel 101 is provided with lateral adjustment sliding holes 102 arranged horizontally, and these holes extend through the entire assembly. The first guide wheel bracket 112 is mounted on the frame and located on the back of the support panel 101. The drive part of the lateral drive component is connected to the first guide wheel bracket 112. In this embodiment, the lateral drive component achieves horizontal movement using a drive cylinder, but it can also be driven using a hydraulic cylinder or an electric cylinder. The lateral guide wheel 111 is located on the front of the support panel 101. One end of the first connecting shaft 113 is connected to the first guide wheel bracket 112, and the other end of the first connecting shaft 113 passes through the lateral adjustment sliding holes 102 and is centrally connected to the lateral guide wheel 111, causing the lateral guide wheel 111 to rotate and connect to the first connecting shaft 113. A first conveying limiting groove 114 for limiting the luggage compartment sealing strip is provided on the outer peripheral wall of the lateral guide wheel 111, ensuring that the luggage compartment sealing strip does not detach from the lateral guide wheel 111 during conveying. The lateral drive component, via a cylinder, moves the lateral guide wheel 111 on the first guide wheel bracket 112 laterally for positioning, further accommodating luggage sealing strips of different sizes. For example... Figure 2 As shown, in this embodiment, there are two transverse guide wheels 111 and two transverse adjustment sliding holes 102, which are spaced vertically and parallel to each other. The first guide wheel bracket 112 is vertically mounted on the back of the support panel 101, and the two transverse guide wheels 111 are rotatably connected to the upper and lower sides of the first guide wheel bracket 112 via the first connecting shaft 113. A transverse drive component enables the two transverse guide wheels 111 to move laterally and synchronously along the corresponding two transverse adjustment sliding holes 102. The synchronous movement of the two transverse guide wheels 111 further increases the transverse adjustment range and tension, ensuring that the luggage compartment sealing strip can be stably tensioned and transported.

[0032] like Figure 1 and Figure 3As shown, the vertical adjustment assembly 12 also includes a vertical drive component, a second guide wheel bracket 122, and a second connecting shaft 123; a vertical adjustment sliding hole 103 is provided on the support panel 101, and the vertical adjustment sliding hole 103 is arranged through the front and rear; the second guide wheel bracket 122 is arranged on the frame and located on the back of the support panel 101; the driving part of the vertical drive component is connected to the second guide wheel bracket 122; in this embodiment, the vertical drive component realizes horizontal movement in the form of a driving cylinder, or it can also be driven in the form of a hydraulic cylinder or an electric cylinder. The vertical guide wheel 121 is located on the front of the support panel 101. One end of the second connecting shaft 123 is connected to the second guide wheel bracket 122, and the other end of the second connecting shaft 123 passes through the vertical adjustment sliding hole 103 and is connected to the center of the vertical guide wheel 121, allowing the vertical guide wheel 121 to be rotatably connected to the second connecting shaft 123. A second conveying limiting groove 124 is provided on the outer peripheral wall of the vertical guide wheel 121 to limit the luggage compartment sealing strip, ensuring that the luggage compartment sealing strip will not detach from the vertical guide wheel 121 during conveying. The vertical guide wheel 121 on the second guide wheel bracket 122 is driven vertically and positioned by a vertical drive component in the form of a cylinder, further matching luggage compartment sealing strips of different sizes. In this embodiment, there are two vertical guide wheels 121 and two second guide wheel brackets 122, and two vertical adjustment sliding holes 103, which are spaced apart and parallel to each other. The second guide wheel brackets 122 are vertically arranged on the back of the support panel 101, and the two vertical guide wheels 121 are rotatably connected to the two second guide wheel brackets 122 through the second connecting shafts 123. The two vertical guide wheels 121 are vertically moved and positioned along the corresponding two vertical adjustment sliding holes 103 by two vertical driving components. The two vertical guide wheels 121 can be controlled separately, thereby further increasing the vertical adjustment range and vertical tension, ensuring that the luggage compartment sealing strip can be stably tensioned and transported. At the same time, the two synchronously moving horizontal guide wheels 111 can make the luggage compartment sealing strip more fully tensioned, thereby further ensuring the stable transport and stable sealing of the luggage compartment sealing strip.

[0033] like Figure 1 , Figure 4 and Figure 5As shown, the transmission drive assembly 13 includes a drive support plate 131, a first drive shaft 132, a first drive wheel 133, a second drive shaft 134, a second drive wheel 135, a drive timing belt 136, and a rotary drive component. The drive support plate 131 is mounted on the frame. The first drive shaft 132 and the second drive shaft 134 are rotatably connected to the drive support plate 131. Both the first drive shaft 132 and the second drive shaft 134 are arranged in a front-rear direction and are laterally spaced. The front end of the first drive shaft 132 is connected to the first drive wheel 135. A drive wheel 133 is connected to the first drive wheel 133, and the front end of the second drive shaft 134 is connected to the second drive shaft 134. A drive timing belt 136 is tensioned and connected to the first drive wheel 133 and the second drive wheel 135. The drive timing belt 136, the horizontal guide wheel 111, and the vertical guide wheel 121 are on the same plane, and the luggage compartment sealing strip is tensioned and connected to the drive timing belt 136, the horizontal guide wheel 111, and the vertical guide wheel 121. A rotary drive component is connected to the first drive shaft 132 or the second drive shaft 134 and is used to drive the first drive shaft 132 or the second drive shaft 134 to rotate. By using a rotary drive component to drive the drive wheel on one of the drive shafts to rotate in the form of a motor, the drive timing belt 136 can be rotated, which in turn can drive the luggage compartment sealing strip tensioned on the drive timing belt 136 to rotate and be conveyed, achieving a stable conveying effect.

[0034] like Figure 5 As shown, the conveyor drive assembly 13 also includes a conveyor baffle 137; the conveyor baffle 137 is vertically arranged, and one rear side of the conveyor baffle 137 is connected to the end of the first drive shaft 132 via a first bearing; the other rear side of the conveyor baffle 137 is connected to the end of the first drive shaft 132 via a second bearing, and the area of ​​the conveyor baffle 137 is larger than the area surrounded by the drive timing belt 136. The conveyor baffle 137 can further limit the luggage compartment sealing strip, preventing the luggage compartment sealing strip from detaching from the drive timing belt 136 during conveying.

[0035] like Figure 1 and Figure 6 As shown, the edge-fixing guide wheel assembly includes several horizontally arranged and spaced-apart edge-fixing guide wheels 21; the edge-adjusting guide wheel assembly includes several horizontally arranged and spaced-apart edge-adjusting guide wheels 22; each edge-adjusting guide wheel 22 has a connecting seat 221 at its bottom; and the connecting seat 221 is movably connected to the edge-fitting bracket 20. The edge-fitting channel 24 can be adjusted by the adjustable edge-fitting guide wheels 22, thereby adapting to different sizes of luggage sealing strips. Figure 7As 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.

[0036] like Figure 1 and Figure 8 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. The adhesive 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 is used to lift and lower 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.

[0037] During operation, the luggage sealing strip is fitted onto all the horizontal guide rollers 111, vertical guide rollers 121, feeding auxiliary guide rollers 203, discharging auxiliary guide rollers 205, and the drive timing belt 136. Simultaneously, the luggage sealing strip is positioned 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 rollers 22 are adjusted, it is ensured 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 rollers 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 compartment sealing strip is tensioned and fitted, the first drive wheel 133 on the first drive shaft 132 is driven to rotate by a drive motor via a rotary drive component, thereby driving the drive timing belt 136 to rotate. The friction between the drive timing belt 136 and the luggage compartment sealing strip is used to rotate and transport the luggage compartment sealing strip. During transport, under the pressure of the edge fixing guide wheel 21 and the edge adjusting guide wheel 22, and with glue injected into the gap of the luggage compartment sealing strip by the glue injection machine 233, the luggage compartment sealing strip is closed. Finally, the entire luggage compartment sealing strip is glued and closed by the luggage compartment sealing strip going around once. After the glue is injected, the luggage compartment sealing strip is removed, and the above actions are repeated for the next luggage compartment sealing strip to be glued and closed.

[0038] The advantages of this invention are that the horizontally adjustable guide wheel 111 and the vertically adjustable guide wheel 121 can better adapt to luggage sealing strips of different sizes. At the same time, the optimal tension of the luggage sealing strip can be adjusted in actual production, thereby achieving better conveying effect and conveying stability, and also facilitating better edge-joining processing. The front-to-back adjustable edge-joining guide wheel group can change the width of the edge-joining channel 24, thereby better adapting to luggage sealing strips of different sizes for edge-joining, ensuring better edge-joining effect and edge-joining quality.
