Description

[Technical Field]

[0001] This utility model belongs to the field of material coil feeding technology, and in particular relates to a material coil feeding mechanism. [Background Technology]

[0002] With the rapid development of photovoltaic power generation, double-glass photovoltaic modules have gradually become a mainstream technology in domestic photovoltaic power generation construction. The basic structure of a double-glass photovoltaic module is a double-layer glass laminate, which consists of an upper glass layer, a lower glass layer, and the encapsulating film and photovoltaic cells sandwiched between them, laminated into a single unit. During transportation and daily use, the edges of double-glass photovoltaic modules are inevitably subject to bumps and knocks, which can easily generate burrs or even cause the module to break. Therefore, edge sealing is a necessary measure. Currently, the industry typically uses edge-wrapping technology for edge protection of double-glass photovoltaic modules, employing edge tape to adhere to the edges of the module. For example, in the case of double-glass photovoltaic modules, the edges are often sealed with edge tape. The photovoltaic module sealing tape module disclosed in Chinese Patent Publication No. CN109326669B can automatically seal the edges of double-glass photovoltaic modules, ensuring the tape is firmly bonded to the photovoltaic module. It includes a single-axis driver, a push-pull cylinder, a tape-applying guide rail, a tape-applying push plate, a tape fixing seat, an edge-sealing initiator, an edge-sealing pressure roller assembly, a cutting assembly, a tape-pressing assembly, and a blocking support. The tape-applying push plate is equipped with a tape fixing seat for holding the tape roll. The tape sequentially passes through the edge-sealing initiator, the cutting assembly, the edge-sealing pressure roller assembly, and the tape-pressing assembly to adhere to the side of the photovoltaic module. However, the following problems exist during continuous material supply:

[0003] (1) Since the material roll is placed horizontally, it tends to shift downward during continuous feeding. Moreover, the shaft on the tape fixing seat in this solution is fixed and the height of the material roll cannot be adjusted, which will cause the tape to shift when it is pasted, reducing the accuracy of tape pasting and thus reducing the yield of sealing.

[0004] (2) The rotation speed of the material roll cannot be adjusted in this solution. If the edge sealing speed of the edge trimming machine needs to be adjusted, the above solution cannot be implemented.

[0005] (3) Place the material roll on the outer periphery of the tape holder, and connect the material roll head to the material pulling mechanism of the processing device. The material roll head moves forward under the pull of the material pulling mechanism, while the material roll rotates on the shaft of the tape holder. During the material roll rotation and feeding process, if the material pulling mechanism stops running due to malfunctions, the material roll will still rotate a certain number of times under the action of inertia because the rotation speed of the material roll cannot be adjusted. This will result in excessive material output and failure to provide a flat feeding effect, thereby affecting the next processing step and wasting a large amount of tape.

[0006] Therefore, it is necessary to provide a material coil feeding mechanism to solve the above-mentioned technical problems. [Utility Model Content]

[0007] The main purpose of this utility model is to provide a material roll feeding mechanism that can solve the problem of downward offset during the material roll feeding process, ensure the accuracy of tape pasting, and also adjust the rotation speed of the material roll to avoid material waste.

[0008] This utility model achieves the above-mentioned objective through the following technical solution: a material roll feeding mechanism, comprising a base, a support shaft with adjustable vertical position disposed on the base, a material roll fixing seat rotatably disposed on the outer periphery of the support shaft, a support plate sleeved on the outer periphery of the support shaft and disposed at the bottom of the material roll fixing seat for supporting the material roll, and an adjustment module disposed on the top of the support shaft for adjusting the rotation speed of the material roll fixing seat. The bottom of the base is provided with a first pressing member pressing against the bottom of the support shaft, and the side of the base is provided with a second pressing member pressing against the outer wall of the support shaft and restricting the movement of the support shaft. The height of the support shaft can be adjusted by adjusting the height of the first pressing member and locking it with the second pressing member.

[0009] Furthermore, the adjustment module includes a brake pad sleeved on the outer periphery of the upper end of the support shaft, a disc spring assembly sleeved on the outer periphery of the support shaft and pressed against the upper surface of the brake pad, and a screw disposed on the top of the support shaft and pressed against the disc spring assembly.

[0010] Furthermore, a bearing sleeve is fixedly installed inside the material roll fixing seat, and several bearings are sleeved on the outer periphery of the support shaft. The support shaft is installed inside the bearing sleeve through several of the bearings.

[0011] Furthermore, the bearing sleeve has a receiving groove at its top for accommodating the brake pad, and the support shaft has a threaded hole at its top for engaging with the screw.

[0012] Furthermore, the upper end of the bearing sleeve is provided with a radially extending annular limiting part that restricts the upward movement of the material roll fixing seat, and the support plate is fixedly disposed at the bottom of the bearing sleeve by a plurality of screws and extends out of the outer periphery of the material roll fixing seat.

[0013] Furthermore, the material roll fixing base includes an annular body and a plurality of elastic support components distributed annularly on the outer periphery of the annular body, and the outer periphery of the annular body is provided with grooves for installing the elastic support components.

[0014] Furthermore, the elastic support assembly includes a support member that is engaged within the groove and is capable of moving radially along the annular body, and a spring disposed inside the support member, the other end of which is disposed on the inner wall of the groove.

[0015] Furthermore, the support member includes an outer support portion and a locking portion that engages with the groove. The groove includes a first groove for mounting the support portion and a second groove for mounting the locking portion. The width of the support portion is smaller than the width of the locking portion, and the width of the first groove is smaller than the width of the second groove.

[0016] Furthermore, the base is provided with a first mounting hole for mounting the support shaft, a second mounting hole for cooperating with the first clamping member, and a third mounting hole for cooperating with the second clamping member. The second mounting hole and the third mounting hole both extend into the first mounting hole and communicate with the first mounting hole. The lower end of the support shaft is set as a plane on the side facing the second clamping member.

[0017] Furthermore, the base is provided with a sensor to detect whether there is a material roll on the support plate or to detect the material usage of the material roll, and the support plate is provided with a first avoidance opening to avoid the detection light of the sensor.

[0018] Compared with the prior art, the beneficial effects of the material roll feeding mechanism of this utility model are as follows:

The height of the support shaft can be adjusted by adjusting the height of the first clamping member and locking it with the second clamping member.

[0020] (2) An adjustment module for adjusting the rotation speed of the material roll fixing seat is provided at the upper end of the support shaft. On the one hand, the rotation speed of the material roll fixing seat can be adjusted by turning the screw up and down, thereby adjusting the rotation speed of the material roll. On the other hand, if a malfunction occurs during the material roll rotation feeding process, the material pulling mechanism can be stopped by directly tightening the screw down to stop the rotation of the material roll fixing seat, thus avoiding a large amount of material waste.

Detailed Implementation Methods

[0034] Please refer to Figures 1-5This embodiment is a material roll feeding mechanism 100. The material roll feeding mechanism 100 includes a base 1, a support shaft 2 that is adjustable in height and is mounted on the base 1, a material roll fixing seat 3 that is rotatably mounted on the outer periphery of the support shaft 2, a support plate 4 that is sleeved on the outer periphery of the support shaft 2 and located at the bottom of the material roll fixing seat 3 to support the material roll 200, and an adjustment module 5 located at the top of the support shaft 2 to adjust the rotation speed of the material roll fixing seat 3. The bottom of the base 1 is provided with a first clamping member 11 that is pressed against the bottom of the support shaft 2, and the side of the base 1 is provided with a second clamping member that is pressed against the outer wall of the support shaft 2 and restricts the movement of the support shaft 2. The height of the support shaft 2 can be adjusted by adjusting the height of the first clamping member 11 and locking it with the second clamping member. Specifically, if it is necessary to adjust the height of the support shaft 2, first loosen the second clamping member, then tighten the first clamping member 11. Adjusting the height of the first clamping member 11 adjusts the height of the support shaft 2. Then, tighten the second clamping member to press it against the outer wall of the support shaft 2, fixing the support shaft 2 to the base 1 and restricting its movement. Therefore, even if the material roll tends to shift downwards during continuous feeding, this problem can be solved by adjusting the height of the support shaft 2, thereby preventing the tape from shifting during application and ensuring the accuracy of tape application.

[0035] A bearing sleeve 6 is fixedly installed inside the material coil fixing seat 3. Several bearings 21 are sleeved on the outer periphery of the support shaft 2. The support shaft 2 is positioned inside the bearing sleeve 6 through the bearings 21. A limiting ring 22 is provided between two adjacent bearings 21 and sleeved on the support shaft 2. The limiting ring 22 can restrict the axial movement of the bearing 21 on the support shaft 2. The support shaft 2 is a stepped shaft, and the lower bearing 21 is located on the shoulder of the support shaft 2 to prevent the bearing 21 from moving downward.

[0036] The upper end of the bearing sleeve 6 is provided with an annular limiting part 61 that extends radially and restricts the upward movement of the material roll fixing seat 3. The material roll fixing seat 3 is sleeved on the outer periphery of the bearing sleeve 6 from the bottom and is flush with the lower surface of the bearing sleeve 6. The annular limiting part 61 restricts the upward movement of the material roll fixing seat 3. The material roll fixing seat 3 and the bearing sleeve 6 are interference fit, so there is no relative rotation between the material roll fixing seat 3 and the bearing sleeve 6. Therefore, the material roll fixing seat 3 and the bearing sleeve 6 rotate together. The support plate 4 is fixed to the bottom of the bearing sleeve 6 by several screws 7 and extends out of the outer periphery of the material roll fixing seat 3. The support plate 4 can restrict the material roll fixing seat 3 from moving downward. When placing the material roll 200, the material roll 200 is fitted onto the outer periphery of the material roll fixing seat 3 and the bottom of the material roll 200 is supported on the support plate 4. On the one hand, the support plate 4 can support the material roll 200. On the other hand, the upper surface of the support plate 4 is flat. If the material roll 200 deviates when it arrives, the bottom surface of the material roll 200 supports the material roll and presses down the deviated position of the material roll, so that the bottom surface of the material roll is completely supported on the support plate 4, which can solve the problem of material roll deviating when it arrives.

[0037] The adjustment module 5 includes a brake pad 51 sleeved on the outer periphery of the upper end of the support shaft 2, a disc spring assembly 52 sleeved on the outer periphery of the support shaft 2 and pressed against the upper surface of the brake pad 51, and a screw 53 set on the top of the support shaft 2 and pressed against the disc spring assembly 52. ​​The bearing sleeve 6 has a receiving groove 62 at the top to accommodate the brake pad 51, and the top end of the support shaft 2 has a threaded hole 23 that mates with the screw 53. The adjustment module 5 can adjust the rotation speed of the material roll 200 by adjusting the rotation speed of the material roll fixing seat 3. The adjustment module 5 adjusts the rotation speed of the material roll fixing seat 3 as follows: If it is necessary to slow down the rotation speed of the material roll fixing seat 3, screw 53 is turned down, the disc spring assembly 52 is compressed, thereby pressing the brake plate 51, and the friction between the brake plate 51 and the bearing sleeve 6 increases, thereby slowing down the rotation speed of the bearing sleeve 6 and the material roll fixing seat 3; If it is necessary to speed up the rotation speed of the material roll fixing seat 3, screw 53 is turned up, and the compression of the disc spring assembly 52 increases. When the disc spring assembly 52 presses against the brake pad 51, the clamping force will decrease, and the friction between the brake pad 51 and the bearing sleeve 6 will decrease. This will increase the rotation speed of the bearing sleeve 6 and the material roll fixing seat 3. Therefore, on the one hand, the rotation speed of the material roll fixing seat 3 can be adjusted by turning the screw 53 up and down, thereby adjusting the rotation speed of the material roll 200. On the other hand, during the material roll rotation feeding process, if a malfunction occurs and the material pulling mechanism stops operating, the screw 53 can be tightened down to stop the material roll fixing seat 3 from rotating, thus avoiding a large amount of material waste.

[0038] The material roll fixing base 3 includes an annular body 31 and a plurality of elastic support components 32 distributed in annularly around the outer periphery of the annular body 31. The outer periphery of the annular body 31 is provided with a groove 311 for installing the elastic support components 32. The elastic support component 32 includes a support member 321 that is engaged in the groove 311 and can move radially along the annular body 31, and a spring disposed inside the support member 321. The other end of the spring is disposed on the inner wall of the groove 311.

[0039] The support member 321 includes an outer support portion 3211 and a locking portion 3212 that engages with the groove 311. The groove 311 includes a first groove 3111 for mounting the support portion 3211 and a second groove 3112 for mounting the locking portion 3212. The width of the support portion 3211 is smaller than the width of the locking portion 3212, meaning the longitudinal section of the support member 321 is a "T" shaped structure. Correspondingly, the width of the first groove 3111 is smaller than the width of the second groove 3112. This design not only simplifies the structure but also ensures the support member 321 is stably locked within the groove 311. One end of the spring is located in the locking portion 3212. The support member 321 is located on the inner wall of the groove 311 on the side wall and on the inner wall of the groove 311. This ensures that the support member 321 can move elastically along the radial direction of the annular body 31, so that the support member 321 can be elastically pressed against the inner side of the material roll 200. When no material roll is placed, the support member 321 protrudes from the outer wall of the annular body 31. When a material roll is placed, the inner side of the material roll 200 presses the support member 321 inward. After the spring is compressed, it provides a preload force to the support member 321, thereby pressing the support member 321 against the inner side of the material roll 200. This enables the material roll 200 to be installed and fixed on the material roll fixing seat 3, making it easy for the material roll 200 to rotate together with the material roll fixing seat 3.

[0040] The base 1 is provided with a first mounting hole 13 for mounting the support shaft 2, a second mounting hole 14 that mates with the first clamping member 11, and a third mounting hole 15 that mates with the second clamping member. The second mounting hole 14 and the third mounting hole 15 both extend into the first mounting hole 13 and communicate with it, so that the first clamping member 11 and the second clamping member can be clamped to the bottom and the outer peripheral sidewall of the support shaft 2, respectively. Since the bottom of the support shaft 2 is flat, the first clamping member 11 can be stably clamped to the bottom of the support shaft 2. In order for the second clamping member to be stably clamped to the outer peripheral sidewall of the support shaft 2, the lower end of the support shaft 2 is set as a flat surface on the side facing the second clamping member. The second clamping member clamps to the flat surface, which can ensure that the second clamping member is stably clamped to the outer peripheral sidewall of the support shaft 2, avoid the shaking of the support shaft 2, and ensure the support stability of the support shaft 2. The first mounting hole 13 is a hole with a smooth inner wall, and the diameter of the bottom of the support shaft 2 is smaller than the diameter of the first mounting hole 13, which facilitates the vertical movement of the support shaft 2 and thus makes it easy to adjust the height of the support shaft 2. In this embodiment, in order to facilitate the tightening of the first clamping member 11 and the second clamping member, both the first clamping member 11 and the second clamping member are threaded screws or bolts. Correspondingly, the second mounting hole 14 and the third mounting hole 15 are threaded holes. In other embodiments, the first clamping member 11 and the second clamping member can be other structures, and their specific structures are not limited here.

[0041] The base 1 is also equipped with a sensor 16 for detecting whether there is a material roll on the support plate 4 or for detecting the material usage of the material roll. Correspondingly, the support plate 4 is equipped with a first avoidance opening 41 to avoid the detection light of the sensor 16. In this embodiment, there are two first avoidance openings 41. In other embodiments, the number of first avoidance openings 41 can be set according to the actual situation, and there is no limitation here.

[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
