Description

Technical Field

[0001] This utility model relates to the field of fabric spreading machine technology, specifically to a pneumatic fabric pressing structure for the pressure plate at the cutter of a multi-layer fabric spreading machine. 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 the cutting table for easy subsequent cutting. During fabric spreading, the fabric is first clamped by a clamping mechanism, then the fabric spreading jaws grab the fabric, and the fabric is spread by driving the jaws to move.

[0003] However, the following problems exist when clamping and pressing the fabric: (1) When clamping the fabric with a clamping mechanism before pulling the fabric, the clamping plate on the clamping mechanism is usually a whole piece, which causes the fabric to be completely covered and makes it difficult to grab the fabric with the fabric pulling claw; (2) After pulling the fabric, the fabric needs to be cut. If the fabric is not pressed after cutting, the movement of the new fabric when pulling the new fabric can easily cause the cut fabric to shift. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pneumatic fabric pressing structure for the pressure plate at the cutter of a multi-layer fabric spreading machine, which solves the problem that the fabric spreading claws are difficult to grip due to the large coverage area of ​​the fabric after it is clamped.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A pneumatic fabric pressing structure for the cutting edge of a multi-layer fabric spreading machine includes two symmetrical wall panels. An upper beam is fixedly connected to the upper part between the two wall panels. Multiple cylinders are installed on the upper beam. All cylinders have a pressure rod connected to their extension and retraction ends. Several equidistant upper pressure blocks are fixed to the bottom surface of the pressure rod. A lower beam is fixedly connected to the lower part between the two wall panels. A support plate is fixedly connected to the lower beam. Several lower pressure blocks that cooperate with the upper pressure blocks are connected to one side of the support plate. The upper pressure blocks and lower pressure blocks correspond one-to-one. There are equal gaps between adjacent upper pressure blocks and between adjacent lower pressure blocks.

[0007] Preferably, the bottom surface of the lower beam is fixedly connected to an outwardly extending pressure plate, the pressure plate is in the same direction as the lower pressure block, and the pressure plate is located below the outer side of the lower pressure block.

[0008] In the above technical solution, after the fabric is cut, the pressure plate can press the fabric onto the fabric spreading machine, so that the cut fabric is also in a compressed state.

[0009] Preferably, a strip-shaped cover is fixedly connected to one side between the two wall panels, and the cover is located above the pressure plate.

[0010] The above technical solution involves installing a linear displacement mechanism inside the housing, and installing a cutting mechanism on the linear displacement mechanism. The linear displacement mechanism drives the cutting mechanism to move laterally, thereby cutting the pulled-out fabric.

[0011] Preferably, mounting plates are fixedly connected to the side of both wall panels away from the pressure plate, and guide rollers are rotatably connected to the two mounting plates via rotary bearings.

[0012] In the above technical solution, the guide rollers play a role in guiding the fabric during the fabric spreading process.

[0013] Preferably, the outer sidewall of the wall panel is fixedly connected to four shafts arranged in a rectangular shape, and rolling bearings are rotatably connected to the shafts. The rolling bearings are slidably connected to the frame of the fabric spreading machine.

[0014] The above technical solution includes a lifting mechanism on the fabric spreading machine, which is connected to the upper beam. The lifting mechanism drives the entire structure of the device to rise. During the rising process, the rolling bearings ensure that the wall panel moves smoothly and evenly along the frame of the fabric spreading machine.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Before the fabric is pulled, the cylinder extends and drives the pressure rod to descend. The upper pressure block presses the fabric tightly onto the lower pressure block. Since there are gaps between adjacent upper pressure blocks and adjacent lower pressure blocks, the fabric pulling claws can easily grab the fabric exposed between the gaps, thus improving the convenience of pulling the fabric.

[0017] (2) After the fabric is cut, the cut fabric falls onto the support plate. Then, by controlling the overall rise of this utility model, the cut fabric can slide onto the fabric pulling machine. When a new fabric is pulled, the entire utility model descends and the cut fabric is pressed tightly onto the fabric pulling machine by the pressure plate. Pulling a new fabric will not affect the cut fabric, thereby preventing the cut fabric from shifting. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-4 A pneumatic fabric pressing structure for the cutting edge of a multi-layer fabric spreading machine includes two symmetrical wall panels 1. An upper beam 2 is fixedly connected to the upper part between the two wall panels 1. A lifting mechanism (not shown in the attached diagram) is installed on the top of the upper beam, and the lifting mechanism is mounted on the fabric spreading machine. The lifting mechanism can be a cylinder, hydraulic cylinder, etc., used to control the raising or lowering of the upper beam.

[0026] Multiple cylinders 3 are installed on the upper beam 2. The telescopic ends of all cylinders 3 are connected to a pressure rod 4. Several upper pressure blocks 5 are fixedly arranged at equal intervals on the bottom surface of the pressure rod 4. A lower beam 6 is fixedly connected between the two wall panels 1. A support plate 7 is fixedly connected to the lower beam 6. Several lower pressure blocks 8 that cooperate with the upper pressure blocks 5 are connected to one side of the support plate 7. The upper pressure blocks 5 and the lower pressure blocks 8 correspond one-to-one. There are equal gaps between adjacent upper pressure blocks 5 and adjacent lower pressure blocks 8. When the upper pressure blocks and lower pressure blocks overlap, the fabric can be clamped and the fabric at the gaps can be exposed for clamping.

[0027] A pressure plate 9 extending outward is fixedly connected to the bottom surface of the lower beam 6. The pressure plate 9 is in the same direction as the lower pressure block 8 and is located below and outside the lower pressure block 8. After the fabric is cut, the pressure plate can press the fabric onto the fabric spreading machine, so that the cut fabric is in a compressed state.

[0028] A strip-shaped cover 10 is fixedly connected to one side between the two wall panels 1, and the cover 10 is located above the pressure plate 9. A linear displacement mechanism (not shown in the attached drawing) is installed inside the cover. This linear displacement mechanism is a screw drive mechanism, and a cutting mechanism (not shown in the attached drawing) is installed on the linear displacement mechanism. The cutting mechanism includes a bracket, a drive motor mounted on the bracket, and a cutter connected to the motor shaft of the drive motor. The bracket is connected to the linear displacement mechanism, and the cutting mechanism is driven to move laterally through the linear displacement mechanism, thereby cutting the pulled-out fabric. The linear displacement mechanism and the cutting mechanism described in this embodiment are both prior art, and will not be described in detail in this embodiment.

[0029] Mounting plates 11 are fixedly connected to the side of each wall panel 1 away from the pressure plate. Guide rollers 12 are rotatably connected to the two mounting plates 11 via rotary bearings. When the fabric is pulled, the guide rollers guide the fabric to be fed between the upper and lower pressure blocks.

[0030] The working principle of this embodiment is as follows: Before pulling the fabric, the extension of the cylinder 3 drives the pressure rod 4 to descend, and the upper pressure block 5 presses the fabric tightly onto the lower pressure block 8. Since there are gaps between adjacent upper pressure blocks 5 and adjacent lower pressure blocks 8, it is convenient for the fabric pulling claw to grab the fabric exposed between the gaps, thus improving the convenience of pulling the fabric. The fabric pulling claw here can be a finger cylinder.

[0031] After the fabric is cut, the cut fabric falls onto the support plate 9. Then, the lifting mechanism pulls the feeding plate 2, controlling the entire device to rise, causing the cut fabric to slide onto the fabric spreading machine. When the fabric spreading claws pull new fabric, the entire device is lowered again, and the pressure plate presses the cut fabric tightly onto the fabric spreading machine (e.g., ...). Figure 2 As shown in the diagram, pulling on new fabric will not affect the fabric being cut, thus preventing the cut fabric from shifting.

[0032] Example 2

[0033] Based on Embodiment 1, four rectangularly arranged shafts 13 are fixedly connected to the outer sidewall of the wall panel 1, and rolling bearings 14 are rotatably connected to the shafts 13. A lifting mechanism is provided on the fabric spreading machine, which is connected to the upper beam. Through the action of the lifting mechanism, the entire structure of this utility model is lifted. During the lifting process, the rolling bearings ensure that the wall panel moves smoothly and evenly along the frame of the fabric spreading machine, improving stability.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
