Description

Technical Field

[0001] This utility model relates to the field of frameless painting processing technology, specifically to a material transfer device for an automatic painting stretching machine. Background Technology

[0002] Frameless paintings, as the name suggests, are paintings without an outer frame, representing a modern decorative trend. By reducing the cost of the outer frame, they are more economical, possess a greater sense of originality, and better align with modern aesthetic preferences.

[0003] There is also a semi-automatic frameless painting processing equipment that can tighten the canvas and perform some steps by machine. Compared with manual operation, it effectively avoids uneven canvas and improves work efficiency to a certain extent. However, the market demand for frameless paintings is increasing, and the existing semi-automatic equipment can no longer meet market needs. The loading process still relies on manual loading, placing the frame on the back of the canvas or paper before feeding the frame and canvas into the semi-automatic equipment. This results in low efficiency, poor accuracy, and inconsistent finished product quality. Furthermore, it can only tighten the canvas on opposite sides of the frame at a time. When tightening the other sides, the frame needs to be manually turned before the canvas and frame are put back into the tightening equipment. This type of equipment cannot process finished products in one go, has low automation, is complex to operate, and has high production costs. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide a material transfer device for an automatic stretching machine.

[0005] To address the above problems, the following technical solution is provided: A material transfer device for an automatic fabric stretching machine, comprising a material placement platform, a first fabric stretching and nailing device, a connecting platform, and a second fabric stretching and nailing device arranged sequentially. The first and second fabric stretching and nailing devices are arranged in an L-shape. The connecting platform is located between the first and second fabric stretching and nailing devices. Each of the first and second fabric stretching and nailing devices is equipped with a clamping and transferring mechanism. The clamping and transferring mechanism includes a support, two sets of clamping components respectively disposed at both ends of the support, and a sliding component that drives the support to move. The material placement platform is provided with a sliding groove for the support to slide. The connecting platform is provided with a T-shaped groove for the two sets of clamping and transferring mechanisms to slide. The T-shaped groove includes a first sliding groove corresponding to the feeding direction of the first fabric stretching and nailing device and a second sliding groove corresponding to the feeding direction of the second fabric stretching and nailing device.

[0006] By adopting the above technical solution, the drawing paper (which can also be canvas, and its material is not limited; for ease of description, it will be referred to as drawing paper below; canvas stretching refers to the action of stretching and stapling the two sides of the drawing paper, not the material of the drawing paper), the drawing paper and the frame are placed on the placement platform one after the other. When the front clamping component clamps the frame and drawing paper on the placement platform, the rear clamping component clamps the semi-finished product with the canvas stretching completed on both sides. The sliding component drives the two sets of clamping components to move backward through the bracket. The clamping components move the frame, drawing paper and semi-finished product to the first stretching and stapling device and the connecting platform respectively. The first stretching and stapling device performs canvas stretching on both sides of the frame and drawing paper. One end of the clamping and transferring mechanism in the direction of the second stretching and stapling device moves to the second slide groove, and the front clamping component clamps the semi-finished product. Then, the two sets of clamping components of the clamping and transferring mechanism in the direction of the first stretching and stapling device release, and the front clamping component in the direction of the second stretching and stapling device moves the semi-finished product into the second stretching and stapling device. The other two sides of the canvas are fastened (simultaneously, the clamping assembly at the rear end of the second fabric fastening device moves the finished canvas fastening product from the second fabric fastening device to the discharge station). When the clamping assembly in the direction of the second fabric fastening device moves the material, the clamping assembly in the direction of the first fabric fastening device retracts to the previous station and repeats the previous step. Compared with existing canvas stretching machines that mostly use platform-type material transfer, where the canvas fastening requires the cooperation of the platform and the fabric fastening device, and the platform moves the canvas fastening to the next station after completing the process at that station, and the work can only continue after the platform is reset, in this technical solution, the material transfer and canvas fastening do not interfere with each other, that is, the two can work simultaneously, which greatly improves work efficiency. At the same time, the clamping and transferring mechanism cooperates with the first fabric fastening device, the connecting platform, and the second fabric fastening device to realize automatic reversing fabric fastening, which is fully automated, greatly improving production efficiency and reducing labor costs.

[0007] The utility model further includes: the first fabric stretching and nailing device includes a first frame, the first frame includes a first support guide rail for placing the picture frame and the drawing paper, the first support guide rail is set at the same height as the material placement platform and the connecting platform, and the first support guide rail is respectively set on both sides of the clamping and transferring mechanism; the second fabric stretching and nailing device includes a second frame, the second frame includes a second support guide rail for placing the picture frame and the drawing paper, the second support guide rail is set at the same height as the connecting platform, and the second support guide rail is respectively set on both sides of the clamping and transferring mechanism.

[0008] By adopting the above technical solution, the first support guide rail and the second support guide rail work together with the material placement platform and the connecting platform to play the role of platform support. Therefore, when the clamping assembly is moving, the first fabric stretching and nailing device or the second fabric stretching and nailing device can place the semi-finished product or the finished product on the first support guide rail and the second support guide rail first, without waiting for the platform to reset before putting it down, thereby further improving production efficiency.

[0009] The utility model further includes the following configuration: a feeding station is provided on the material placement platform; a first fabric stretching station is provided on the first frame; the length of the support is adapted to the distance between the feeding station and the first fabric stretching station; the length of the support is greater than the distance between the first fabric stretching station and the second chute; a second fabric stretching station and a discharge station are provided on the second frame; and the distance between the first chute and the second fabric stretching station, and the distance between the second fabric stretching station and the discharge station are both adapted to the length of the support.

[0010] By adopting the above technical solution, when the front clamping component clamps the picture frame and paper at the feeding station, the rear clamping component clamps the semi-finished products of the canvas stretching nails on both sides at the first stretching station. The sliding component drives the two sets of clamping components to move backward through the bracket. When the front clamping component moves to the first stretching station, the rear clamping component moves into the first slide groove and is located at the rear end of the second slide groove. At this time, one end of the clamping and transferring mechanism in the direction of the second stretching nailing device moves to the second slide groove, and its front clamping component clamps the semi-finished product on the connecting platform. The two clamping components of the clamping and transferring mechanism in the direction of the first fabric stretching and nailing device are released. The clamping component at the front end in the direction of the second fabric stretching and nailing device moves the semi-finished product to the second fabric stretching station. At the same time, the clamping component at the rear end in the direction of the second fabric stretching and nailing device moves the finished product with four-sided fabric stretching and nailing from the second fabric stretching station to the discharge station. Preferably, when the rear clamping component moves the frame into the first chute, the central axis of the frame coincides with the central axis of the second chute, and the central axis of the second chute coincides with the central axis of the second fabric stretching and nailing device.

[0011] The utility model is further configured such that: a first sliding frame is provided below the first supporting guide rail, and a first sliding base is provided on each side of the first sliding frame; the sliding direction of the first sliding base is perpendicular to the feeding direction of the first fabric stretching and nailing device; the first supporting guide rail is provided on the first sliding base; and the first sliding base is electrically connected to the control mechanism.

[0012] By adopting the above technical solution, the control mechanism can adjust the distance between the first support rails on both sides by controlling the first sliding base to slide along the first sliding frame. It can be applied to picture frames of different sizes, which greatly improves the applicability of the equipment. Compared with manual adjustment, CNC adjustment has high precision, simple operation, convenient use and high efficiency.

[0013] The utility model further includes: the clamping assembly includes a top clamping plate and a bottom clamping plate arranged vertically. The horizontal height of the bottom clamping plate is lower than the horizontal height of the picture frame when it is located on the material placement platform, and the horizontal height of the top clamping plate is higher than the horizontal height of the picture frame when it is located on the material placement platform. The top clamping plate and the bottom clamping plate can move relative to each other to clamp or loosen the picture frame and the drawing paper.

[0014] By adopting the above technical solution, the bottom clamp and the top clamp are inserted into the upper and lower parts of the picture frame and the drawing paper respectively, and the upper and lower clamps are used. The structure is simple and easy to operate. During the clamping process, the picture frame remains at the same height as the material placement platform. The material placement platform plays a supporting role, making it less prone to shaking and more stable when moving the material.

[0015] The utility model is further configured such that the top clamping plate is detachably connected to the bracket, and the bottom clamping plate is connected to the first cylinder on the bracket.

[0016] The utility model is further configured such that: the bottom clamping plate is detachably connected to the bracket, the top clamping plate is connected to the second cylinder on the bracket, and the top clamping plate is an extension plate extending towards the bottom clamping plate.

[0017] By adopting the above technical solution, the structure is simple and the operation is convenient.

[0018] The utility model is further configured such that: the bottom clamping plate is connected to the first cylinder on the bracket, the top clamping plate is connected to the second cylinder on the bracket, the first cylinder and the second cylinder are distributed along the sliding direction of the bracket, and the top clamping plate is an extension plate extending towards the first cylinder.

[0019] By adopting the above technical solution, two cylinders are used for double clamping to increase the clamping strength and prevent the paper and frame from shifting during the movement, thus ensuring the accuracy of material transfer. The structure is simple and highly stable. Attached Figure Description
