Description

Technical Field

[0001] The present invention relates to a machine for making cloth, and more particularly to a cloth pulling machine. Background Art

[0002] A cloth pulling machine is a machine for making cloth that emerged in the early 1990s. Since flexible materials are mostly produced and transported in rolls, when they reach the user's factory, an important process is to convert the rolled materials into a multi-layer planar state for convenient cutting and use. Automated production equipment such as automatic cloth pulling machines and automatic cloth laying machines came into being. In the process of making automobile seats, pulling out the fabric is the first process, and the quality of cloth pulling and cutting is an important prerequisite for making automobile seats that meet the specifications. Existing cloth pulling machines include a workbench, a fabric placement rack, and an automatic cutting mechanism. The fabric placement rack is installed at the end of the workbench, and the automatic cutting mechanism is arranged on the work platform. During operation, two workers need to stand on both sides of the work platform to place the fabric on the fabric placement rack, and then the two of them pull the fabric until the required length and lay it flat on the work platform, and then cut it through the automatic cutting mechanism. The workers then pull the material and cut again, and so on in a cycle. With a cloth pulling machine having such a structure, although automatic cutting of the fabric can be achieved, two workers are still required to pull the cloth, resulting in high labor costs and low work efficiency; on the other hand, work areas for the workers are left on both sides of the work platform, occupying a large area. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a cloth pulling machine with a simple structure, simple operation and capable of single-person operation. Using a device with such a mechanism can reduce labor costs and improve work efficiency.

[0004] The technical solution adopted by the present invention to solve the above technical problems is as follows: A cloth pulling machine includes a frame, a work platform and a cutting device. The work platform is slidably arranged on the frame. The frame is provided with front and rear limit devices for restricting the movement stroke of the work platform. A fabric pressing device is arranged between the work platform and the frame. An automatic feeding device is arranged at the end of the frame. The cutting device is arranged on one side of the automatic feeding device.

[0005] The described fabric pressing device includes a first pressing shaft, a second pressing shaft, a pressing shaft connecting member, and a pressing shaft lifting mechanism. The first pressing shaft and the second pressing shaft are respectively rotatably connected to the working platform through the pressing shaft connecting member. The frame includes a base and a mounting frame. The working platform is slidably disposed on the base. The mounting frame includes a first support column and a second support column respectively disposed on both sides of the base. A first support crossbar is horizontally disposed on the first support column. The pressing shaft lifting mechanism includes a roller, a lifting plate, and a lifting plate reset assembly. The roller is rotatably connected to the outer end of the first pressing shaft. The upper end of the lifting plate has a lifting surface that slopes downward from top to bottom towards the front end of the working platform. The roller can slide along the lifting surface. A roller limiting groove is provided at the highest point of the lifting surface. The lower end of the lifting plate is provided with a roller avoiding portion protruding outward. The roller avoiding portion is disposed opposite to the roller limiting groove. An opening roller avoiding groove is provided inside the roller avoiding portion. The roller avoiding portion is mounted on the first support crossbar through a mounting shaft. The lifting plate reset assembly is disposed at the free end of the lifting plate.

[0006] In this structure, the first pressing shaft and the second pressing shaft are rotatably connected to the working platform through the pressing shaft connecting member. At this time, the first pressing shaft and the second pressing shaft press on the working platform. Manually push the working platform to slide along the base. After the first pressing shaft moves to the starting end of the lifting plate, the roller on the first pressing shaft moves upward along the lifting surface and is caught in the roller limiting groove. At this time, the first pressing shaft and the second pressing shaft are lifted. The worker straightens the fabric and makes the front end of the fabric flush with the front end of the working platform. Continue to push the working platform to drive the roller out of the limiting groove, so that the first pressing shaft and the second pressing shaft fall to press the fabric. Push the working platform until the front and rear limiting devices catch the working platform, and pull the working platform back to make the fabric straighten to the required length (that is, the front and rear limiting devices catch the working platform), realizing a single person to pull out the fabric; Since the roller avoiding portion of the lifting plate is mounted on the first support crossbar through a mounting shaft, the free end of the lifting plate can rotate around the mounting shaft. During the roller reset process, the roller first moves along the roller avoiding groove, and then the lifting plate is pushed outward by extrusion during the forward movement of the roller, so that the roller smoothly avoids the lifting plate. The lifting plate is reset under the action of the lifting plate reset assembly; It can be seen that the worker can easily lift the first pressing shaft and the second pressing shaft through the lifting plate and press the fabric, which has the advantages of simple operation and easy implementation.

[0007] The lifting plate reset assembly described above includes a reset spring, a spring mounting shaft, and a support arm. The support arm includes a fixed portion and a mounting portion perpendicularly connected to the fixed portion. The fixed portion is fixed to the first support crossbar through a mounting post. The spring mounting shaft is disposed between the free end of the mounting portion and the free end of the lifting plate. The reset spring is sleeved on the spring mounting shaft and is located between the mounting portion and the lifting plate. In this structure, after the free end of the lifting plate is pushed outwards by the roller, it slowly resets under the action of the reset spring, which has a protective effect on the lifting plate and prevents the lifting plate from hitting the working platform.

[0008] The pressing shaft connecting member described above includes a connecting rod, a first connecting shaft, and a second connecting shaft. The connecting rod is disposed below the working platform. The first connecting shaft is vertically disposed at one end of the connecting rod, and the first connecting shaft is rotatably fixed to a side wall of the working platform through a rotating shaft. The second connecting shaft is vertically disposed at the other end of the connecting rod, and the second connecting shaft is rotatably fixed to the other side wall of the working platform through a rotating shaft. One end of the first pressing shaft is fixed to the upper end of the first connecting shaft. One end of the second pressing shaft is fixed to the upper end of the second connecting shaft. A buffer is disposed between the second connecting shaft and the working platform. One end of the buffer is fixed to the lower bottom surface of the second connecting shaft, and the other end of the buffer is fixed to the lower bottom surface of the working platform. In this structure, the second pressing shaft is connected to the first pressing shaft through the connecting rod. When the first pressing shaft is lifted by the lifting plate, the second pressing shaft is lifted simultaneously, which simplifies the structure and facilitates operation. In addition, a buffer is disposed between the second connecting shaft and the working platform. The buffer ensures that the first pressing shaft and the second pressing shaft slowly press on the fabric to be cut, avoiding the first pressing shaft and the second pressing shaft falling rapidly and damaging the fabric or the working platform, and has the advantage of being silent. The buffer is a prior art, such as a door closer.

[0009] The base described above includes two horizontally disposed support rods and support legs disposed at both ends of each support rod. A plurality of sliding wheels are disposed on the bottom surface of the working platform. An upwardly protruding slide rail is disposed on the support rod. A chute matching the slide rail is disposed on the sliding wheel. In this structure, it is ensured that the working platform slides smoothly on the base.

[0010] The front and rear limiting device described above includes a front limiting member, a rear limiting member, a left limiting rod, and a right limiting rod. The left limiting rod and the right limiting rod are respectively arranged on both sides of the slide rail on the left side. Both ends of the left limiting rod are fixed on the support leg, and both ends of the right limiting rod are fixed on the support leg. The front limiting member is movably arranged on the right limiting rod. The front limiting member includes a first clamping hoop and a front limiting block arranged at one end of the first clamping hoop. The front limiting block is arranged opposite to the hub of the sliding wheel at the front. The rear limiting member is movably arranged on the left limiting rod. The rear limiting member includes a second clamping hoop and a rear limiting block arranged at one end of the second clamping hoop. The rear limiting block is arranged opposite to the hub of the sliding wheel at the rear. In this mechanism, the left limiting rod and the right limiting rod are provided to prevent the sliding wheel from derailing. The first clamping hoop is arranged on the right limiting rod, and the second clamping hoop is arranged on the left limiting rod. The first clamping hoop and the second clamping hoop are of a detachable connection structure, and their specific positions can be adjusted according to actual needs. The front limiting block and the rear limiting block play a role in limiting, ensuring the movement stroke of the working platform, and thus ensuring that the sizes of each piece of cut fabric are the same.

[0011] The automatic feeding device described above includes a fabric placement rack and a driving mechanism. The fabric placement rack is installed on the base through a mounting seat. The fabric placement rack includes a support shaft, fabric placement arms, and a transfer arm. The support shaft is rotatably connected to the mounting seat. The fabric placement arms are fixed to both ends of the support shaft through the transfer arm. The fabric placement arms and the transfer arm are perpendicular to each other. A fabric mounting plate is arranged at the top of the fabric placement arms. Mounting holes are arranged on the fabric mounting plate. A fabric placement entrance communicating with the mounting holes is also arranged on the fabric mounting plate. The driving mechanism drives the support shaft to rotate so that the fabric placement arms are in a horizontal or vertical state with respect to the ground. In this structure, the driving mechanism drives the support shaft to rotate, driving the transfer arm to rotate 90°, so that the transfer arm is perpendicular to the ground. At this time, the fabric placement arms are parallel to the ground and descend, facilitating workers to place the heavy fabric roll to be cut on the fabric support arms. After placement, the driving mechanism drives the support shaft to rotate in the reverse direction, driving the transfer arm to rotate 90°, so that the transfer arm is horizontal with respect to the ground. At this time, the fabric placement arms are perpendicular to the ground and the fabric roll to be cut rises, facilitating the fabric to be cut to be pulled into the working platform.

[0012] The driving mechanism includes a servo motor, a speed reducer, a first sprocket, a second sprocket and a chain. The output end of the servo motor is connected to the speed reducer. The first sprocket is installed on the output end of the speed reducer. The second sprocket is fixed on the support shaft. The first sprocket and the second sprocket are connected by the chain. A tensioning sprocket is further arranged between the first sprocket and the second sprocket.

[0013] It further includes a fabric flattening mechanism and a fabric anti-slip mechanism. The fabric flattening mechanism is arranged at the rear side of the cutting device. The fabric flattening mechanism includes two columns and two central shafts arranged vertically. The central shafts are horizontally fixed between the two columns. Sleeve tubes are sleeved on the central shafts. A gap for the fabric to pass through is left between the upper and lower sleeve tubes. The two columns are respectively fixed on the first support column and the second support column.

[0014] The fabric anti-slip mechanism includes an anti-slip cloth and an anti-slip cloth mounting rod. The anti-slip cloth mounting rod is fixed on the lower central shaft through a mounting rod connecting arm. One end of the anti-slip cloth is fixed on the anti-slip cloth mounting rod, and the other end of the anti-slip cloth is fixed on the cutting tool holder of the cutting device. The anti-slip cloth mounting rod is located below the cutting tool holder. The fabric flattening machine is used to prevent the fabric from wrinkling when being pulled out. After the fabric to be cut is cut by the cutting device, part of it remains on the anti-slip cloth, which can prevent the fabric to be cut from slipping and is convenient for the worker to pull it next time.

[0015] A fabric baffle is arranged at the front end of the working platform. The fabric baffle is installed on the front wall of the working platform through a hinge. A magnet for attracting the fabric baffle is arranged on the front wall of the working platform. A pushing handle is further arranged at the front end of the working platform. The fabric baffle is installed on the front wall of the working platform through a hinge, and a magnet for attracting the fabric baffle is arranged on the front wall of the working platform, which is convenient for the fixing and downward turning of the fabric baffle. When the fabric baffle is fixed, it is convenient for the front end of the fabric to be aligned; when the fabric baffle is turned downward, it is convenient for the cut fabric to be taken out of the working platform.

[0016] Compared with the prior art, the present invention discloses a fabric pulling machine. Since the working platform is slidably arranged on the frame, front and rear limiting devices for restricting the movement stroke of the working platform are arranged on the frame. A fabric pressing device is arranged between the working platform and the frame, and an automatic feeding device is arranged at the end of the frame. During operation, only one worker needs to push the working platform, pull the fabric to the front end of the working platform, continue to push the working platform to press the front end of the fabric to be cut through the fabric pressing device. After the front and rear limiting devices limit the rear end of the working platform, pull back the working platform until the front and rear limiting devices limit the front end of the working platform, and the cutting device cuts the fabric to obtain the required length. Repeating the above steps can continue cutting. Thus, it can be seen that using this equipment can not only achieve automatic cutting, but also realize single-person fabric pulling, reduce labor costs, improve work efficiency, and at least double the work benefit compared to the original; on the other hand, since only one person stands in front of the working platform instead of on both sides of the working platform, it reduces the floor area occupied by the application of this fabric pulling machine.
