[0002] In the production of photovoltaic modules, several factors have hindered the development of automation. For example, during the edge sealing process of photovoltaic panels, there are issues such as the lack of recycling of the adhesive tape backing paper. These defects make it easy for encapsulation failures to occur during the automated production of photovoltaic resistors. Accumulation of adhesive tape backing paper can cause blockages, leading to machine malfunctions. Repairing these issues is time-consuming, labor-intensive, costly, and inefficient.

[0003] To address the aforementioned issues, Chinese Patent Application No. 201721800924.5 discloses an automatic tape backing paper recycling device. This disclosed automatic recycling device includes: a support assembly; a drive element; a rotating shaft, one end of which is connected to the drive element; a recycling assembly, sleeved on and pivotally connected to the rotating shaft, comprising a recycling tray and a recycling cover; the recycling tray and the recycling cover are connected; a synchronization control assembly, sleeved on and engaged with the rotating shaft, comprising a locking piece abutting against the recycling cover, an elastic element, and a fixing block; the fixing block is fixed to the rotating shaft, and both ends of the elastic element abut against the fixing block and the locking piece, respectively; and a guide assembly, connected to the support assembly. Chinese Patent Application No. 201921462215.X discloses a tape sealing module and its automatic reel changing device. The disclosed tape sealing module includes a tape roll with tape wound around it. The tape includes a backing paper and tape segments. The tape segments are distributed at fixed lengths and intervals on the backing paper. The tape passes over a backing paper drive wheel and a second guide wheel before entering a first tape channel. Then, it passes over the pasting end and enters a second tape channel. Finally, it connects and is fixed to a backing paper recycling wheel after passing the first guide wheel. The first tape channel, the second tape channel, and the pasting end are all set on the tape guide shell. The end of the tape guide shell away from the pasting end is assembled and fixed to the frame. The frame is also hinged to the housing of the tape cylinder, and the tape extension shaft of the tape cylinder is hinged to the drive connecting plate.

The other end of the first connecting plate is assembled and fixed to one end of the second connecting plate, and the other end of the second connecting plate is rotatably assembled to the pressure wheel.

[0004] In the aforementioned prior art, a drive element drives a rotating shaft to rotate, and a recycling assembly is fitted onto the rotating shaft. The recycling of the bottom paper is achieved by rotating the recycling disc. In the above scheme, the conveyor belt and the recycling of the bottom paper are carried out separately. When recycling the bottom paper, the recycling of the bottom paper and the conveyor belt are easily out of sync, which can cause the bottom paper to accumulate or become over-tensioned and break during recycling, thus making it impossible to effectively complete the recycling of the bottom paper. Utility Model Content

[0005] The present invention aims to overcome the defects in the prior art and provide a packaging tape supply device that enables the self-recycling of the backing paper without accumulation or breakage due to tension during recycling.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a packaging tape supply device with self-recovering bottom paper, comprising a fixed frame and a tape supply mechanism and a bottom paper recycling mechanism mounted on the fixed frame, wherein the tape supply mechanism and the bottom paper recycling mechanism rotate on the fixed frame; the tape supply mechanism includes a tape reel for placing the tape and a tape wheel for driving the tape reel to rotate; the bottom paper recycling mechanism includes a bottom paper reel for winding the bottom paper and a bottom paper wheel for driving the bottom paper reel to rotate.

[0007] In a preferred embodiment of this utility model, the belt pulley is located in the middle of the belt reel, and a drive pulley connected to the belt pulley is located below the belt pulley.

[0008] As a preferred embodiment of this utility model, the belt pulley is provided with a one-way rotating shaft connected to the drive pulley, and the one-way rotating shaft drives the belt pulley to rotate unidirectionally in the direction of belt movement.

[0012] In a preferred embodiment of this utility model, both the driving wheel and the driven wheel are located at the bottom of the fixed frame, and the driving wheel and the driven wheel are at the same height.

[0013] As a preferred embodiment of this utility model, the fixing frame is equipped with tape guide wheels for guiding the tape. The tape guide wheels are all arranged on the moving path of the tape, and the tape guide wheels are located at the point where the tape separates from the backing paper.

[0014] As a preferred embodiment of this utility model, the fixing frame is equipped with a bottom paper guide wheel for guiding the bottom paper. The bottom paper guide wheel is located on the movement path of the bottom paper and is located at the point where the tape separates from the bottom paper.

[0015] In a preferred embodiment of this utility model, the tape guide wheel and the bottom paper guide wheel are located on opposite sides of the tape.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 2. Furthermore, through the synchronous belt connected to the driving wheel and the driven wheel, the driven wheel drives the bottom paper wheel and bottom paper tray to rotate with the driving wheel under the action of the synchronous belt, thereby ensuring that the supply of tape and the recycling of bottom paper are synchronized, thus ensuring that the bottom paper can be recycled smoothly.

[0019] 3. Furthermore, by setting a one-way rotating shaft, the belt pulley and belt reel can only rotate in one direction, ensuring that the belt and the bottom paper do not move in opposite directions during belt supply and bottom paper recycling. Attached Figure Description

Detailed Implementation

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1-5 As shown, a self-recovering packaging tape supply device includes a chassis 6. The chassis 6 is equipped with a tape supply mechanism 1, a bottom paper recycling mechanism 2, a tape packaging mechanism 3, a feed reset mechanism 4, and a cutting mechanism 5. The feed reset mechanism 4 includes a fixed frame 403 mounted on the chassis 6. The tape supply mechanism 1, the bottom paper recycling mechanism 2, the tape packaging mechanism 3, and the cutting mechanism 5 are all mounted on the fixed frame 403. The chassis 6 is also equipped with a first reset cylinder 401 for controlling the working state of the tape packaging mechanism 3 and a second reset cylinder 402 for controlling the working state of the cutting mechanism 5. The tape packaging mechanism 3 includes a tape application wheel assembly 3011, a tape anti-detachment clamp 3021, a solar panel guide wheel 303, and an anti-detachment wheel assembly 3041 arranged sequentially along the tape movement path.

[0029] Furthermore, the tape supply mechanism 1 and the bottom paper recycling mechanism 2 are both fixedly mounted on the fixed frame 403. The tape packaging mechanism 3 and the cutting mechanism 5 are slidably connected to the fixed frame 403. The output end of the first reset cylinder 401 is connected to the tape packaging mechanism 3, and the tape packaging mechanism 3 is moved through the first reset cylinder 401. The output end of the second reset cylinder 402 is connected to the cutting mechanism 5, and the cutting mechanism 5 is moved through the second reset cylinder 402.

[0030] In addition, the tape passes through the tape-applying wheel assembly 3011, the tape anti-detachment clip 3021, the solar panel guide wheel 303, and the anti-detachment wheel assembly 3041 in sequence. The tape-applying wheel assembly 3011 and the anti-detachment wheel assembly 3041 are arranged opposite to each other, and the tape anti-detachment clip 3021 and the solar panel guide wheel 303 are both located between the tape-applying wheel assembly 3011 and the anti-detachment wheel assembly 3041. The solar panel passes through the tape-applying wheel assembly 3011, the tape anti-detachment clip 3021, the solar panel guide wheel 303, and the anti-detachment wheel assembly 3041 in sequence.

[0031] During adhesive application, the solar panel is clamped by the adhesive application wheel assembly 3011, and the tape anti-detachment clip 3021 moves the tape to the edge of the solar panel, ensuring the tape adheres to the panel. The anti-detachment wheel assembly 3041 then presses the tape firmly onto the solar panel, guaranteeing a secure bond and preventing it from detaching. This improves both the quality and efficiency of the edge sealing process. Simultaneously, the tape anti-detachment clip 3021 prevents collisions between the tape sealing mechanism 3 and the solar panel, and also prevents the tape from folding, ensuring the safety of the solar panel. The solar panel guide wheel 303 provides guidance and support to the applied solar panel, preventing uneven tape application.

[0032] The tape sealing mechanism 3 also includes a tape-applying cylinder 301 for controlling the clamping state of the tape-applying roller assembly 3011, a tape anti-detachment reset cylinder 302 for controlling the position of the tape anti-detachment clamp 3021, and an anti-detachment cylinder 304 for controlling the clamping of the anti-detachment roller assembly 3041. Furthermore, the tape-applying cylinder 301, tape anti-detachment reset cylinder 302, and anti-detachment cylinder 304 are all mounted on the fixed frame 403. The tape-applying cylinder 301 adjusts the spacing of the tape-applying roller assembly 3011, thereby clamping the solar panel. The tape anti-detachment reset cylinder 302 moves the tape anti-detachment clamp 3021, ensuring that the tape anti-detachment clamp 3021 is pushed out to the tape fold edge. The anti-detachment cylinder 304 adjusts the spacing of the anti-detachment roller assembly 3041, ensuring that the anti-detachment roller assembly 3041 can clamp the solar panel and firmly adhere the tape to the solar panel.

[0033] Both the tape supply mechanism 1 and the bottom paper recycling mechanism 2 are fixedly installed on the fixed frame 403, and the tape supply mechanism 1 and the bottom paper recycling mechanism 2 rotate on the fixed frame 403. The tape supply mechanism 1 includes a tape reel 101 for placing tape and a tape wheel 102 for driving the tape reel 101 to rotate. The tape reel 101 is provided with a tape wheel 102 in the middle, which drives the tape reel 101 to rotate synchronously. The tape reel 101 and the tape wheel 102 are coaxially arranged.

[0034] The belt pulley 102 is located in the middle of the belt reel 101. Below the belt pulley 102, there is a drive pulley 103 connected to the belt pulley 102. The drive pulley 103, the belt pulley 102 and the belt reel 101 are coaxially arranged. The belt pulley 102 is used to install the belt, and the belt reel 101 is used to carry the belt. The drive pulley 103, the belt pulley 102 and the belt reel 101 rotate synchronously.

[0035] In addition, both the tape reel 101 and the bottom paper reel 201 are located above the fixing frame 403, and the tape reel 101 and the bottom paper reel 201 are at the same height.

[0036] The belt pulley 102 is provided with a one-way rotating shaft 104, and the drive wheel 103 is installed at the end of the one-way rotating shaft 104 to connect the bottom paper recycling mechanism 2 and drive the bottom paper recycling mechanism 2 to rotate.

[0037] The one-way rotating shaft 104 includes a one-way bearing disposed in the belt pulley 102 and a rotating shaft connected to the one-way bearing. The drive wheel 103 is disposed at the bottom end of the rotating shaft. Through the cooperation between the one-way bearing and the rotating shaft, the belt pulley 102 is driven to rotate unidirectionally in the direction of belt movement.

[0038] The bottom paper recycling mechanism 2 includes a bottom paper tray 201 rotatably mounted on a fixed frame 403. The bottom paper tray 201 has a bottom paper wheel 202 for winding the bottom paper in the middle. The bottom paper wheel 202 has a rotating shaft 204 on it. The end of the rotating shaft 204 has a driven wheel 203. A synchronous belt 105 for driving the driven wheel 203 to rotate is connected between the driven wheel 203 and the driving wheel 103.

[0039] Furthermore, the bottom paper roller 202 is used to recycle the bottom paper of the adhesive tape, and the bottom paper tray 201 is used to carry the adhesive tape. The bottom paper tray 201, the bottom paper roller 202, the rotating shaft 204 and the driven wheel 203 are coaxially arranged. The bottom paper roller 202 is located in the middle of the bottom paper tray 201, and the rotating shaft 204 is connected to the bottom paper roller 202 and drives the bottom paper roller 202 to rotate. The rotating shaft 204 drives the bottom paper tray 201, the bottom paper roller 202 and the driven wheel 203 to rotate. At the same time, the driving wheel 103 and the driven wheel 203 are connected by the synchronous belt 105, thereby realizing the rotation of the adhesive tape supply mechanism 1 and the bottom paper recycling mechanism 2.

[0040] In addition, both the driving wheel 103 and the driven wheel 203 are located at the bottom of the fixed frame 403, and the driving wheel 103 and the driven wheel 203 are at the same height.

[0041] When adhesive is applied to the solar panel, the tape drives the tape pulley 102 to rotate, which in turn drives the tape reel 101, the one-way rotating shaft 104, and the drive wheel 103 to rotate synchronously. At the same time, the drive wheel 103 drives the synchronous belt 105 to move, which in turn drives the driven wheel 203 to rotate, which in turn drives the rotating shaft 204, the bottom paper wheel 202, and the bottom paper reel 201 to rotate synchronously, so that the rotating bottom paper wheel 202 can retract the bottom paper.

[0042] A tape guide wheel 4032 is installed on the fixing frame 403 to guide the tape. The tape guide wheel 4032 is set on the movement path of the tape and is located at the separation point of the tape and the backing paper. At the same time, a tape guide wheel 4032 is also set at the tape entry end of the tape anti-detachment clamp 3021. The tape guide wheel 4032 guides the movement path of the tape, thereby ensuring that the tape will not get tangled or jammed during the movement, thus ensuring that the solar panel can be applied smoothly.

[0043] The mounting frame 403 is equipped with a bottom paper guide wheel 4033 for guiding the bottom paper. The bottom paper guide wheel 4033 is set on the movement path of the bottom paper and is located at the separation point of the tape and bottom paper. The bottom paper guide wheel 4033 guides the movement path of the bottom paper, thereby ensuring that the bottom paper will not get tangled during the recycling process and ensuring the smooth recycling of the bottom paper.

[0044] Furthermore, the tape guide wheel 4032 and the backing paper guide wheel 4033, located at the point where the tape separates from the backing paper, are respectively located on opposite sides of the tape, guiding the tape and the backing paper in two directions respectively.

[0045] A groove 601 is formed on the chassis 6. The bottom of the fixing frame 403 is provided with a slider 4031 that cooperates with the groove 601. Furthermore, the groove 601 is provided at opposite ends of the chassis 6. The slider 4031 is slidably disposed in the groove 601. The connection between the slider 4031 and the groove 601 is realized, thereby realizing the connection between the fixing frame 403 and the chassis 6. At the same time, the position of the fixing frame 403 can also be adjusted.

[0046] The first reset cylinder 401 and the second reset cylinder 402 are arranged in parallel. The first reset cylinder 401 controls the sliding position of the tape sealing mechanism 3 on the fixed frame 403, and the second reset cylinder 402 controls the sliding position of the cutting mechanism 5 on the fixed frame 403. Furthermore, the first reset cylinder 401 and the second reset cylinder 402 are both fixedly mounted on the chassis 6. The positions of the tape sealing mechanism 3 and the cutting mechanism 5 are adjusted by the first reset cylinder 401 and the second reset cylinder 402. When applying adhesive to the solar panel, the first reset cylinder 401 and the second reset cylinder 402 push the tape sealing mechanism 3 and the cutting mechanism 5 to the working position, respectively. After the adhesive is applied, the first reset cylinder 401 and the second reset cylinder 402 pull the tape sealing mechanism 3 and the cutting mechanism 5 back to their original positions, thereby reducing the space occupied by the tape sealing mechanism 3 and the cutting mechanism 5.

[0047] The cutting mechanism 5 is located between the tape anti-detachment clamp 3021 and the solar panel guide wheel 303. The cutting mechanism 5 includes a cutting adjustment cylinder 501 mounted on the fixed frame 403. The output end of the cutting adjustment cylinder 501 is equipped with a cutting cylinder 502 for cutting the tape. The output end of the cutting cylinder 502 is equipped with a tape cutting scissor 503. Furthermore, the cutting adjustment cylinder 501 is vertically arranged, and the output end of the cutting adjustment cylinder 501 moves upward toward the fixed frame 403. The cutting cylinder 502 is mounted on the output end of the cutting adjustment cylinder 501 and is positioned downward. The tape cutting scissor 503 is positioned toward the tape. During the cutting operation, the cutting adjustment cylinder 501 is inflated, causing the cutting cylinder 502 to move downward to the cutting position. Then, the cutting cylinder 502 inflates and closes the tape cutting scissor 503 to complete the cutting operation.

[0048] like Figure 6As shown, a copper sleeve 2021 is also provided inside the bottom paper roller 202. The copper sleeve 2021 is sleeved on the rotating shaft 204. A brake ring 2041 is sleeved on the rotating shaft 204. The lower end of the copper sleeve 2021 abuts against the brake ring 2041. A spring 2042 is provided at the top of the rotating shaft 204, and the bottom end of the spring 2042 abuts against the upper surface of the bottom paper roller 202. Specifically, the copper sleeve 2021 is fixedly connected to the bottom paper roller 202 and rotates synchronously with the bottom paper roller 202. The brake ring 2041 is fixedly set on the rotating shaft 204, and the brake ring 2041 is fixed to the rotating shaft 204. 4. Synchronous rotation; An external thread is formed on the top of the rotating shaft 204, and a nut 2043 is threadedly connected to it. The upper end of the spring 2042 abuts against the lower surface of the nut 2043. Tightening the nut 2043 downwards causes the spring 2042 to be in a compressed state. Under the pressure of the spring 2042, the copper sleeve 2021 abuts against the brake ring 2041. The friction between the copper sleeve 2021 and the brake ring 2041 causes the brake ring 2041 to drive the copper sleeve 2021 to rotate synchronously, thereby driving the bottom paper wheel 202 and the bottom paper disc 201 to rotate, thus realizing the recycling of the bottom paper.

[0049] The supply of tape causes the entire tape to rotate, which in turn drives the tape reel 101 to rotate. Under the action of the synchronous belt 105, the rotating shaft 204 rotates. When the tension of the tape is greater than the friction between the copper sleeve 2021 and the brake ring 2041, relative sliding occurs between the copper sleeve 2021 and the brake ring 2041. At this time, the bottom paper wheel 202 slips. During the process of the friction between the brake ring 2041 and the copper sleeve 2021 driving the bottom paper wheel 202 to rotate, the bottom paper wheel 202 is always tightly attached to the bottom paper being wound, thereby ensuring that the unwinding of the tape and the rewinding of the bottom paper are synchronized.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
