An automatic alignment structure between a clamping device and a discharge port

Abstract

This utility model discloses an automatic alignment structure between a clamping device and a discharge port, comprising two symmetrically arranged wall panels, each with a slidingly connected lifting side plate on its opposite surface. A clamping device for gripping fabric is connected between the two lifting side plates. The wall panels are equipped with a lifting mechanism that controls the simultaneous raising and lowering of the two lifting side plates. One wall panel has an outwardly extending first bracket with a position receiver mounted on it. A second bracket, opposite the first bracket, is installed at the discharge port, with a position transmitter cooperating with the position receiver mounted on it. The position transmitter emits a signal, and the position receiver receives the signal. Before clamping the fabric, a signal is emitted by the position transmitter at the discharge port and received by the position receiver on the wall panel. When the position receiver receives the signal, it indicates that the clamping device is aligned with the discharge port and has reached the desired fabric-pulling height, thus adapting to a discharge port with a constant height.

Description

Technical Field

[0001] This utility model relates to the field of fabric spreading machine technology, specifically to a structure for automatic alignment of a clamping device and a discharge port. Background Technology

[0002] Fabric spreading machines are mainly used in the pre-process of garment or textile production. They are responsible for unrolling rolls of fabric and laying them layer by layer on a cutting table for subsequent cutting. During fabric spreading, a conveyor feeds the fabric from the outlet, then a clamping device holds the fabric. Driving the clamping device pulls the fabric. After spreading, a cutting mechanism cuts the fabric. After cutting, a pressure plate presses the fabric firmly onto a support plate below the outlet, and the clamping device continues to spread new fabric. Due to the continuous spreading and cutting, the thickness of the fabric on the support plate gradually increases, causing the new fabric exiting the outlet to rise higher and higher. This makes it difficult for the clamping device to accurately pull the newly output fabric each time. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic alignment structure between the clamping device and the discharge port, thereby solving the problem that the current clamping device is difficult to align with the discharge port, making it difficult to grab newly produced fabric.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] An automatic alignment structure for a clamping device and a discharge port includes two symmetrically arranged wall panels. Lifting side plates are slidably connected to the opposite surfaces of the two wall panels. A clamping device for gripping fabric is connected between the two lifting side plates. A lifting mechanism is provided on the wall panels to control the simultaneous lifting of the two lifting side plates. One wall panel has an outwardly extending first bracket, on which a position receiver is mounted. A second bracket, opposite to the first bracket, is mounted at the discharge port. A position transmitter, cooperating with the position receiver, is mounted on the second bracket. The position transmitter transmits a signal, and the position receiver receives the signal.

[0006] Preferably, the lifting mechanism includes a drive shaft rotatably connected to the upper end of the two wall panels via a rotary bearing, a motor installed on the outer side of one of the wall panels, the motor shaft of the motor being connected to one end of the drive shaft via a coupling, the lifting mechanism also includes sprockets fixedly connected to both ends of the drive shaft, connecting plates fixedly connected to the outer sides of the two lifting side panels, and connecting blocks fixed to the wall panels and located below the drive shaft, each sprocket being connected to a chain, one end of each chain being fixedly connected to the connecting plate on its respective side, and the other end of each chain being fixedly connected to the connecting block on its respective side.

[0007] The above technical solution involves starting the motor, which drives the transmission shaft to rotate. The two sprockets on the transmission shaft drive the chain to move, and the two chains drive the two lifting side plates to move together, thereby driving the clamping device to lift and lower.

[0008] Preferably, vertical guide rails are fixedly connected to the opposite surfaces of the two wall panels, and sliding grooves are provided on both sides of the guide rails. Multiple opposing axles are connected to the outer sides of the two lifting side panels, and pulleys are rotatably connected to the outer ends of the axles through rotary bearings. The two opposing pulleys slide in the sliding grooves on both sides of the guide rails respectively.

[0009] The above technical solution improves the stability of the lifting side panel during lifting by using pulleys, guide rails, and slide rails.

[0010] Preferably, a limiting rod is fixedly connected to the upper part of the inner side of the two wall panels, and a limiting wheel is rotatably connected to the limiting rod via a rotary bearing. The limiting wheel is located above the sprocket to restrict the movement of the chain between the sprocket and the limiting wheel.

[0011] The above technical solution prevents the chain from falling off the sprocket when it moves along the sprocket, thus improving the stability of the sprocket and the chain.

[0012] Preferably, a fixing rod is connected to the upper part between the two lifting side plates.

[0013] The above technical solution allows the two lifting side plates to be further connected into a whole through the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention is installed on a fabric spreading machine. The clamping and pulling device is used to clamp the fabric output from the discharge port and pull the fabric. Before clamping the fabric, a signal is sent through the position transmitter at the discharge port and received by the position receiver on the wall plate. When the position receiver receives the signal, it indicates that the clamping and pulling device is aligned with the discharge port and has reached the fabric spreading height, thus adapting to the discharge port with a constant height.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1-5 An automatic alignment structure between the clamping and pulling device and the discharge port is applied to a fabric pulling machine. The fabric pulling machine has a clamping and pulling device 1 and a discharge port 2. The fabric is fed into the discharge port 2 by a conveying device, and then the fabric is clamped by the clamping and pulling device 1. The fabric is pulled by driving the clamping and pulling device 1. After the fabric is pulled, the fabric is cut by a cutting mechanism. After the cutting is completed, the fabric is pressed tightly onto the bearing plate 22 below the discharge port by a pressure plate. Then, the clamping and pulling device 1 continues to pull new fabric.

[0025] The clamping and pulling device and the automatic alignment structure of the discharge port described in this embodiment include two symmetrically arranged wall plates 3. The wall plates 3 have screw holes and are fixed to both sides of the fabric spreading machine by bolts. Lifting side plates 4 are slidably connected to the opposite surfaces of the two wall plates 3. Specifically, vertical guide rails 15 are fixedly connected to the opposite surfaces of the two wall plates 3. Slide grooves 16 are provided on both sides of the guide rails 15. Multiple opposing axles 17 are connected to the outer sides of the two lifting side plates 4. The outer ends of the axles 17 are rotatably connected to pulleys 18 via rotary bearings. The two opposing pulleys 18 slide within the slide grooves 16 on both sides of the guide rails 15. During movement, the lifting side plates 4, through the cooperation of the pulleys 18, guide rails 15, and slide grooves 16, improve the stability of their lifting motion.

[0026] A clamping device 1 for gripping fabric is connected between the two lifting side plates 4. The clamping device 1 here can be a number of finger cylinders arranged side by side. Finger cylinders are existing technology and are not the technical solution to be solved in this embodiment. Therefore, this embodiment will not describe the specific structure and principle of the clamping device in detail.

[0027] The wall panel 3 is equipped with a lifting mechanism that controls the simultaneous lifting and lowering of the two lifting side panels 4. Specifically, the lifting mechanism includes a drive shaft 9 rotatably connected to the upper ends of the two wall panels 3, a motor 10 installed on the outer side of one of the wall panels, and a motor shaft 10 connected to one end of the drive shaft 9 via a coupling. The lifting mechanism also includes sprockets 11 fixedly connected to both ends of the drive shaft, connecting plates 12 fixedly connected to the outer sides of the two lifting side panels, and a connecting block 13 fixed to the wall panel and located below the drive shaft. Each sprocket 11 is connected to a chain 14, one end of which is fixedly connected to the connecting plate 12 on its respective side, and the other end of which is fixedly connected to the connecting block 13 on its respective side. When the motor 10 is started, it drives the drive shaft 9 to rotate, and the two sprockets 11 on the drive shaft 9 drive the chains 14 to move. The two chains 14 drive the two lifting side panels 4 to move together, thereby driving the clamping device 1 to lift and lower, so as to adjust the height of the clamping device.

[0028] Limiting rods 19 are fixedly connected to the upper inner sides of the two wall panels 3. Limiting wheels 20 are rotatably connected to the limiting rods 19 via rotary bearings. The limiting wheels 20 are located above the sprocket 11 to restrict the movement of the chain 14 between the sprocket 11 and the limiting wheels 20. When the chain 14 moves along the sprocket 11, the limiting wheels 20 prevent the chain 14 from falling off the sprocket 11, thus improving the stability of the sprocket 11 and the chain 14.

[0029] One of the wall panels 3 has an outwardly extending first bracket 5, on which a position receiver 6 is mounted. A second bracket 7, opposite the first bracket 5, is mounted on one side of the discharge port 2. A position transmitter 8, cooperating with the position receiver 6, is mounted on the second bracket 7. The position transmitter 8 emits a signal, and the position receiver 6 receives the signal. The position transmitter 8, position receiver 6, and motor 10 are all electrically connected to the main controller of the fabric spreading machine. In this embodiment, both the position transmitter 8 and the position receiver are photoelectric sensors. The position transmitter 8 emits infrared light or laser light, and the position receiver 6 receives the infrared light or laser light. When the position receiver 6 receives the light emitted by the position transmitter 8, the motor stops working, indicating that the clamping device has reached the required height.

[0030] The working principle of this embodiment is as follows:

[0031] The clamping and pulling device 1 is used to clamp the fabric output from the discharge port 2 and pull the fabric. Before clamping the fabric, a signal is sent through the position transmitter 8 at the discharge port 2 and received through the position receiver 6 on the wall panel. When the position receiver 6 receives the signal, it indicates that the clamping and pulling device 1 is aligned with the discharge port 2 and reaches the fabric pulling height, thus adapting to the discharge port 2 with a constant height.

[0032] Example 2

[0033] Based on Embodiment 1, a fixing rod 21 is connected to the upper part between the two lifting side panels 4. The lower ends of the two wall panels are connected together by a clamping device, and the upper ends of the two wall panels are further connected together by the fixing rod 21, which improves the stability of the overall structure.
