Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for winding machines, and in particular to an automatic spindle loading device for a spare spindle of a winding machine. Background Technology

[0002] Currently, in non-woven fabric and film winding equipment, after the finished product is rolled to the specified length and the roll is pushed out, the spare winding shaft above enters the winding position, and the original spare position needs to be replenished with a new spare shaft. Some equipment manufacturers have overhead cranes in their workshops, making it convenient to hoist the winding shaft; however, some equipment manufacturers do not have overhead cranes, or are unable to use them due to workshop space limitations. In this case, the shaft needs to be manually lifted and placed in the designated position.

[0003] Manually lifting the shaft is time-consuming and labor-intensive. When the preparation position is high or the winding shaft is heavy, it requires a certain level of physical fitness from the workers lifting the shaft, which is not conducive to safe production. In addition, lifting the shaft requires the intervention of two people, which increases labor costs.

[0004] Therefore, it is necessary to improve the structure of the upper shaft device of the spare shaft of the winding machine to improve the efficiency and safety of the upper shaft. Utility Model Content

[0005] The purpose of this invention is to provide an automatic spindle loading device for a winding machine, which can automate the loading process and reduce the risks caused by manual operation.

[0006] To achieve the above-mentioned utility model objectives, this utility model provides an automatic spindle mounting device for a winding machine, comprising a frame, a spindle clamping mechanism, a positioning mechanism, and a drive mechanism;

[0007] The clamping mechanism is provided on both sides of the frame and is connected to the drive mechanism. The clamping mechanism includes a swing arm, a first clamping plate, a second clamping plate, a clamping cylinder, a lifting cylinder, and a first sensing element. The first clamping plate is connected to the swing arm, and the clamping cylinder is connected to the second clamping plate via the first clamping plate. The first clamping plate has a clamping groove, and the second clamping plate has a clamping head. The clamping groove and the clamping head are positioned to match each other. The sensing head of the first sensing element faces the clamping groove. The lifting cylinder is connected to the first clamping plate via the swing arm.

[0008] Positioning mechanisms are provided on both sides of the frame. Each positioning mechanism includes a positioning cylinder, a connecting plate, a positioning plate, and a second sensing element. The positioning cylinder is connected to the positioning plate through the connecting plate, and the top surface of the positioning plate is provided with a positioning groove. The sensing head of the second sensing element faces the positioning groove.

[0009] As a further improvement of the utility model, the driving mechanism includes a driving component and a chain drive assembly, the chain drive assembly being connected to the driving component, and the swing arm being connected to the chain drive assembly.

[0010] Furthermore, the drive mechanism also includes a tension wheel and a buffer cylinder, the tension wheel being in contact with the chain of the chain drive assembly, and the tension wheel being connected to the buffer cylinder.

[0011] As a further improvement of the utility model, the swing arm is provided with a guide rail assembly, and the swing arm is connected to the first clamping plate through the guide rail assembly.

[0012] As a further improvement of the utility model, the positioning plate is provided with a limiting inclined surface, and the lowest position of the limiting inclined surface is connected to the positioning groove.

[0013] This utility model discloses an automatic spare shaft mounting device for a winding machine. The spare shaft to be mounted is positioned on both sides of the machine frame, above a positioning plate. A second sensor, such as a proximity switch, detects the spare shaft's positioning and sends a signal to the control box. The control box then controls a positioning cylinder to raise the connected positioning plate, lifting the spare shaft and positioning it in the positioning slots at both ends to prevent shaft movement or misalignment. The control box then sends a command to the drive mechanism, causing the swing arm to rotate and the second clamping plate to approach the spare shaft. When the first sensor (which can be a proximity switch) detects the spare shaft at a certain distance, it sends a signal to the control box. The clamping cylinder receives the command and moves the second clamping plate, clamping the spare shaft in the clamping slots. The clamping head provides positioning and clamping. The drive mechanism then rotates and resets the swing arm, completing the spare shaft mounting process and placing the spare shaft in the spare position on the winding machine.

[0014] The advantages of the automatic spare shaft loading device for a winding machine of this utility model compared with the prior art are as follows:

[0015] (1) By setting up sensors, the position of the spare shaft can be identified, making automatic clamping more accurate;

[0016] (2) The positioning mechanism can both position the shaft and remove the shaft from the frame, making it convenient to clamp the shaft;

[0017] (3) Install lifting cylinders to avoid interference with the winding operation when the swing arm swings back and forth;

[0018] (4) The backup shaft is automatically loaded, reducing human intervention and ensuring safety and stability. Attached Figure Description

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

[0028] like Figure 1 As shown, the present invention discloses an automatic spindle loading device for a winding machine, comprising a frame 1, a spindle clamping mechanism 2, a positioning mechanism 3, and a drive mechanism 4.

[0029] Both sides of the frame 1 are equipped with shaft clamping mechanisms 2, which are connected to the drive mechanism 4, such as... Figure 2 As shown, the clamping mechanism 2 includes a swing arm 21, a first clamping plate 22, a second clamping plate 23, a clamping cylinder 24, a lifting cylinder 26, and a first sensing element 27. The first clamping plate 22 is connected to the swing arm 21, and the clamping cylinder 24 is connected to the second clamping plate 23 through the first clamping plate 22. The first clamping plate 22 is provided with a clamping groove 221, and the second clamping plate 23 is provided with a clamping head 231. The clamping groove 221 and the clamping head 231 are positioned to match each other. The sensing head of the first sensing element 27 faces the clamping groove 221. The lifting cylinder 26 is connected to the first clamping plate 22 through the swing arm 21.

[0030] The drive mechanism 4 includes a drive component 41 and a chain drive assembly 42. The chain drive assembly 42 is connected to the drive component 41, and the swing arm 21 is connected to the chain drive assembly 42. The drive component 41 can be a combination of a motor and a reducer, using the meshing of the chain and sprocket teeth to transmit power and motion, causing the connected swing arm 21 to rotate. The rotation angle and direction of the swing arm 21 can be controlled as needed by controlling the running time or forward and reverse rotation of the motor.

[0031] The drive mechanism 4 also includes a tension wheel 43 and a buffer cylinder 44. The tension wheel 43 contacts the chain of the chain drive assembly 42, and the tension wheel 43 and the buffer cylinder 44 are connected. The tension wheel 43 and the buffer cylinder 44 cooperate with each other to ensure smooth chain drive and ensure that a heavy spare shaft can be supported when the shaft is being loaded.

[0032] Positioning mechanisms 3 are provided on both sides of the frame 1, such as Figure 3 As shown, the positioning mechanism 3 includes a positioning cylinder 31, a connecting plate 32, a positioning plate 33, and a second sensing element 34; the positioning cylinder 31 is connected to the positioning plate 33 through the connecting plate 32, and the top surface of the positioning plate 33 is provided with a positioning groove 331; the sensing head of the second sensing element 34 faces the positioning groove 331.

[0033] This utility model discloses an automatic spindle loading device for a winding machine's spare spindle, such as... Figure 4 As shown, the two ends of the spare shaft 5, which needs to be mounted, are placed on both sides of the frame 1 and above the positioning plate 33. The second sensor 34 can be a proximity switch. When the second sensor 34 senses that the spare shaft 5 is in place, it transmits a signal to the control box. The control box controls the positioning cylinder 31 according to the signal to raise the positioning plate 33 connected to it, thereby lifting the spare shaft 5 and positioning it in the positioning grooves 331 at both ends to prevent the shaft from shaking or deviating. Figure 5 As shown, the control box then sends a command to the drive mechanism 4, causing the swing arm 21 to rotate and the second clamping plate 23 to move closer to the spare shaft 5, as shown. Figure 6-7 As shown, when the first sensing element 27 (which can be a proximity switch) senses the spare shaft 5 at a certain distance, it sends a signal to the control box. The clamping cylinder 24 receives the command and moves the second clamping plate 23, clamping the spare shaft 5 in the clamping groove 221. The clamping head 231 performs positioning and clamping functions. Figure 8 As shown, the drive mechanism 4 then rotates and resets the swing arm 21, completing the process of mounting the spare shaft 5, that is, placing the spare shaft 5 in the spare position of the winding machine.

[0034] During the loading of the spare shaft 5, in order not to interfere with the winding shaft in operation, before the swing arm 21 rotates to clamp the shaft, the first clamping plate 22 and the second clamping plate 23 can be pushed to the top of the swing arm 21 by the lifting cylinder 26. The position of the positioning mechanism 3, i.e. the position of the shaft placement, is also selected in a suitable position. After the swing arm 21 returns to its position with the spare shaft 5, the position of the spare shaft 5 can be lowered by the lifting cylinder 26 to facilitate the loading of the spare shaft in the future.

[0035] The swing arm 21 is equipped with a guide rail assembly 25, and the swing arm 21 is connected to the first clamping plate 22 through the guide rail assembly 25. The guide rail assembly 25 can be an existing straight rail and slider assembly. The first clamping plate 22 is connected to the straight rail through the slider. The first clamping plate 22 is raised and lowered under the action of the lifting cylinder 26. The straight rail plays a guiding and limiting role to prevent the first clamping plate 22 from being misaligned and affecting the position of the clamping shaft.

[0036] The positioning plate 33 is provided with a limiting inclined surface 332. The lowest position of the limiting inclined surface 332 is connected to the positioning groove 331. When the second clamping plate 23 moves toward the spare shaft 5, the spare shaft 5 can adjust the distance along the limiting inclined surface 332 within a small range, so that the second clamping plate 23 can clamp the shaft surface more accurately.

[0037] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
