Description

Technical Field

[0001] This application relates to the field of automatic roll changing technology, and in particular to an automatic roll changing device that does not require the machine to stop. Background Technology

[0002] In industrial production, the processing of roll-type raw materials is widely used in textiles, packaging, printing, and other fields. The unwinding mechanism, as a key piece of equipment, passively or actively unwinds the raw materials, ensuring a stable material supply during processing. Its high-precision tension control capabilities greatly improve processing quality and efficiency, driving the development of related industries and providing crucial technical support for modern manufacturing.

[0003] Currently, for unwinding roll-type raw materials, common unwinding mechanisms mainly adopt a fixed design, typically including components such as a reel, drive unit, and tension control system. These mechanisms achieve continuous material supply by fixing the raw material to the reel and combining it with the drive unit. To ensure the stability of the processing, tension sensors and adjustment devices are usually equipped to monitor and adjust the material tension in real time. In addition, some improved solutions introduce auxiliary devices, such as guide rollers and clamping mechanisms, to further optimize the material conveying performance.

[0004] However, existing unwinding mechanisms generally suffer from a significant drawback: they cannot achieve automatic splicing or material changing without stopping the machine. When a roll of raw material is used up, the machine must be stopped, the used material fixing device manually removed, and the next roll of raw material reinstalled. This process is time-consuming and severely impacts production efficiency. Therefore, solving the problem of excessive downtime during material changing has become a pressing technical bottleneck that needs to be overcome. Utility Model Content

[0005] To overcome the aforementioned technical problems, this application provides an automatic roll changing device that does not require the machine to stop.

[0006] This application provides an automatic roll changing device that does not require machine operation, employing the following technical solution:

[0008] By adopting the above technical solution, a non-stop automatic roll changing mechanism is realized, which can effectively solve the problem of the need to stop the machine during material changing in existing unwinding mechanisms. The fixing plate is equipped with a bonding mechanism, an adhesive dispensing mechanism, and a roll feeding mechanism, forming an integrated roll changing structure to ensure that all components work together and improve roll changing efficiency. A bonding pressure roller is installed on the bonding table and driven by a downward pressure cylinder, which can precisely control the bonding pressure and ensure the stability and reliability of material joining. Cutting jaws are arranged adjacent to the bonding pressure roller to achieve rapid cutting and fixing of materials, shortening roll changing time. An adhesive retention groove is opened on the bonding table, which, together with the peeling block in the adhesive dispensing mechanism, achieves accurate peeling and positioning of the sponge adhesive, ensuring the bonding quality at the material joining point.

[0013] Preferably, the fixed plate is provided with a movable slide groove, and at least two transfer rollers are provided in the movable slide groove.

[0014] By adopting the above technical solution, the movable chute allows the transfer roller to move flexibly on the fixed plate. The configuration of at least two transfer rollers can achieve stable support and guidance for the raw materials, thereby ensuring a smooth transition of materials during the roll changing process and improving the reliability and efficiency of the automatic roll changing mechanism without stopping the machine.

[0015] Preferably, the movable chute consists of three chutes connected end to end, with a discharge port provided at the connection of two of the chutes, and a discharge channel provided in the discharge port.

[0016] By adopting the above technical solution, the moving chute consists of three chutes connected end to end, enabling the transfer roller to move and be positioned flexibly within the chute. A discharge port is opened at the junction of two chutes, and a discharge chute is installed within the discharge port to easily discharge waste materials or excess material, avoiding interference with the normal production process and thus improving the stability and efficiency of equipment operation.

[0017] Preferably, the cutting gripper can retract into the fixing plate.

[0018] By adopting the above technical solution, the retractable function of the cutting gripper in the automatic roll changing mechanism without stopping the machine is realized. The cutting gripper can retract into the fixed plate, avoiding interference with the material conveying path when not in operation, thus improving the stability of equipment operation.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses an automatic roll changing device that does not require machine operation, referring to... Figure 1 and Figure 2 It includes a fixing plate 4, on which an adhesive mechanism, an adhesive dispensing mechanism and a roll feeding mechanism are provided.

[0033] The winding feeding mechanism includes a winding storage bin 31 for storing coil material. The winding storage bin 31 has an outlet 32 ​​connected to a guide ramp 34. A transfer platform 35 is fixedly installed at the end of the guide ramp 34. An electrically controlled door 33 is also installed on the outlet 32. The electrically controlled door 33 controls the opening and closing of the outlet 32. When the electrically controlled door 33 is open, the coil material can roll out through the guide ramp 34 at the outlet 32. The coil material rolling out of the outlet 32 ​​rolls along the guide ramp 34 to the transfer platform 35. A baffle is installed at the end of the transfer platform 35 to block the coil material and keep it on the transfer platform 35 for loading.

[0034] Reference Figure 3The fixed plate 4 has a movable chute 44, and a transfer roller 43 is installed in the movable chute 44. In this embodiment, there are two transfer rollers 43. The movable chute 44 consists of three chutes connected end to end. A discharge port 45 is opened at the connection of two of the chutes, and a discharge slide 46 is opened in the discharge port 45. The transfer roller 43 can move along the chute, which facilitates the feeding and transportation of the roll material and the unloading and transportation of the used roll waste. The arrangement of the three chutes makes the movable chute 44 triangular in shape, and a feeding position 47, a discharging position 48 and a feeding position 49 are formed at the three corners of the movable chute 44, respectively. Among them, the feeding position 49 is close to the transfer table 35, the feeding position 47 is located directly above the feeding position 49, and the discharge port 45 is opened at the discharging position 48. Both the loading position 49 and the unloading position 48 are equipped with drive devices for retracting or extending the intermediate transfer roller 43 from the fixed plate 4. This arrangement facilitates the loading and unloading of the coil material. The intermediate transfer roller 43 first transports the coil material from the transfer table 35 upwards to the conveying position 47 at the loading position 49. Upon reaching the conveying position 47, the intermediate transfer roller 43 rotates and unloads the coil material. Several intermediate conveying rollers 16 are provided on the fixed plate 4, and the coil material is transported towards the processing equipment under the guidance of the intermediate conveying rollers 16.

[0035] Reference Figure 4 A bonding platform 14 is fixedly mounted on the fixed plate 4, and a scraper 51 is provided at one end of the bonding platform 14 facing the transfer platform 35. The scraper 51 extends a certain distance towards the transfer platform 35, so that the roll material on the transfer platform 35 can directly contact the scraper 51. After the transfer roller 43 feeds the roll material at the feeding position 49, it will first rotate at the feeding position 49 to make the roll material rotate and fall off. The detached end of the newly fed roll material will move along the scraper 51. As the transfer roller 43 continues to rotate, the end of the roll material will move onto the bonding platform 14. The bonding platform 14 has a glue retention groove 52, and a position sensor is provided in the glue retention groove 52. The end of the roll material will continue to move onto the glue retention groove 52. When the position sensor detects the end, the transfer roller 43 stops driving the roll material to rotate.

[0036] The bonding mechanism includes a bonding pressure roller 11 positioned above the bonding table 14. The bonding mechanism also includes a pressing cylinder 15 that drives the bonding pressure roller 11. An intermediate conveying roller 16 guides the roll material's transfer path to the bonding pressure roller 11, allowing the roll material to pass through the bonding pressure roller 11 during discharge. Adjacent to the bonding pressure roller 11 are cutting grippers 13, which are used to cut the roll material. To maintain stable equipment operation and prevent the cutting grippers 13 from interfering with the movement of the roll material, a driving device is installed within the fixed plate 4. This driving device allows the cutting grippers 13 to retract into the fixed plate 4 when not in use.

[0037] The adhesive dispensing mechanism is configured as conventionally, including a peeling block 21 for peeling the sponge adhesive, an dispensing roller 22, a take-up roller 23, and a driven conveyor roller 24. One side of the sponge adhesive has adhesive residue. When the sponge adhesive passes through the peeling block 21, it will separate from the film material. The film material will then be guided by the driven conveyor roller 24 to the take-up roller 23 to be rolled up. The sponge adhesive will remain on the adhesive retention trough 52 with the adhesive side of the sponge adhesive facing upwards.

[0038] The implementation principle of this application embodiment is as follows: The non-stop automatic roll changing device provided in this application has the effect of changing roll material without stopping the machine. Before operation, the operator needs to place several rolls of material into the storage hopper 31 in advance to ensure that the device has a certain replacement margin. The electrically controlled door 33 is controlled by the device. When there is no replaceable roll material on the transfer table 35, the electrically controlled door 33 will open, allowing the internal roll material to roll along the guide ramp to the transfer table 35.

[0039] When the device is used for the first time, the roll material needs to be fed. The device drives the transfer roller 43 to move along the moving chute 44 to the feeding position 47. The first feeding requires manual arrangement of the roll material feeding route so that the plastic route is transported along a fixed route. The transfer roller 43 will rotate and feed the roll material at the feeding position 47.

[0040] The glue dispensing mechanism automatically feeds the sponge glue, ensuring that there is always a piece of sponge glue waiting to be used in the glue retention tank 52.

[0041] The end of the newly fed roll material will move along the scraper 51 to the glue retention groove 52. Under the control of the position sensor, the end of the new roll material will be pressed on the sponge glue, and the pressed area will not exceed half of the sponge glue area.

[0042] When the roll material is about to run out, the device first controls the cutting gripper 13 to extend and place the material in the middle of the cutting blade. The pressing cylinder 15 drives the bonding roller 11 to press down, pressing the material at the bottom of the bonding roller 11 onto the sponge adhesive at the bottom. During this process, the bonding roller 11 simultaneously presses the end of the new roll material together with the old material, thus bonding the new and old materials. Then, the cutting gripper 13 cuts the old roll material. The transfer roller 43 moves the used roll material waste to the feeding port. At the feeding port, the transfer roller 43 is driven by the drive device to retract into the fixed plate 4. During this process, the roll material waste is detached and falls into the feeding chute below. The transfer roller 43 moves the new roll material along the moving chute 44 to the feeding position 47, and begins to rotate and discharge the new roll material.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
