Description

Technical Field

[0001] This utility model relates to the field of mouse pad manufacturing technology, and specifically to an automatic edge-locking machine for mouse pads. Background Technology

[0002] In the process of manufacturing mouse pads, in order to ensure that the stitches on the sides of the mouse pad are neat, beautiful, flat and firm, an overlock machine is usually needed to repair and process the sides of the mouse pad.

[0003] However, existing mouse pad edge-locking machines are not suitable for automated positioning of mouse pads during edge-locking. Manual positioning is usually required to ensure the quality of the edge-locking. However, human operation is subject to certain errors. When affected by external factors, the mouse pad may shift, affecting the processing quality, resulting in defective products, and reducing work efficiency and quality.

[0004] To address the aforementioned issues, a Chinese utility model patent application (application number 202223333369.3) entitled "An Edge-Sealing Machine for Mouse Pad Production" has been filed. This machine includes a main body, a positioning mechanism, and an edge-sealing mechanism. The positioning mechanism is located above the main body, and the edge-sealing mechanism is located above the positioning mechanism. The main body includes an edge-sealing machine body, support feet, anti-slip pads, and a support plate. The support feet are fixedly installed at the lower end of the edge-sealing machine body and are evenly distributed there. The anti-slip pads are fixedly installed at the lower end of the support feet. This edge-sealing machine for mouse pad production, by installing the positioning mechanism, enables the machine body to position the mouse pad during edge-sealing, preventing the mouse pad from shifting during the edge-sealing process and affecting processing quality. It also solves the problem of traditionally requiring manual fixing of the mouse pad, improving the automation and stability of the mouse pad production process.

[0005] However, mouse pads are generally rectangular, requiring edge locking on all four sides. The aforementioned edge locking machine used in mouse pad production can only lock one side of the mouse pad. As a result, after locking one side of the mouse pad, the positioning mechanism needs to be released, and the mouse pad needs to be manually rotated so that the other side of the mouse pad is below the positioning mechanism. Then the positioning mechanism is used to position it again, and finally the edge locking mechanism locks the edge. This process requires multiple manual operations to complete the edge locking of all four sides of the mouse pad. This results in low production efficiency, high labor intensity, and is not conducive to improving market competitiveness.

[0006] In view of the above, the inventors propose the following technical solution. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic edge-locking machine for mouse pads.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The automatic mouse pad edge-locking machine includes: a worktable for supporting the mouse pad and an edge-locking device installed on one side of the worktable for sewing the edge of the mouse pad to achieve edge locking.

[0014] Furthermore, in the above technical solution, the pressing component is a buffer with a spring buffer head at its end; a baffle for guiding the edge of the mouse pad is also provided on one side of the worktable.

[0015] Furthermore, the above technical solution also includes a pressing and conveying device for pressing down the mouse pad and driving the mouse pad to move linearly.

[0024] Figure 6 This is a partial cross-sectional view of Embodiment 2 of this utility model. Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments and accompanying drawings. Example 1:

[0026] See Figure 1-4 As shown, an automatic mouse pad edge-locking machine includes a worktable 1 and an edge-locking device 2. The worktable 1 is used to support the mouse pad, and the edge-locking device 2 is installed on one side of the worktable 1 and is used to sew the edges of the mouse pad to achieve edge locking.

[0027] The workbench 1 is also provided with an auxiliary edge-locking device 3 for pressing down the mouse pad and driving the mouse pad to rotate around the part where its corner is connected to the seam to change direction. The auxiliary edge-locking device 3 includes: a pressing member 31 for pressing down the non-corner part of the mouse pad, a lifting drive module 32 for driving the pressing member 31 to rise and fall, and a rotation drive mechanism 33 for driving the lifting drive module 32 to rotate. The rotation axis of the rotation drive mechanism 33 is located directly above the part where the corner of the mouse pad is connected to the seam.

[0028] During operation, the edge-locking device 2 first sews a stitch along one straight edge of the mouse pad placed on the workbench 1 to achieve edge locking. When the edge-locking device 2 sews to or is about to sew to the corner of the mouse pad, the lifting drive module 32 in the auxiliary edge-locking device 3 drives the pressing member 31 to press down. The pressing member 31 presses down on the non-corner position of the mouse pad, and the rotation drive mechanism 33 drives the lifting drive module 32 and the pressing member 31 to rotate. Since the rotation axis of the rotation drive mechanism 33 is located at the corner of the mouse pad and connected to the stitching, The mouse pad is positioned directly above the corner, which is connected by stitching. This causes the pressing member 31 to press down on the mouse pad and drive it to rotate around the point where the corner connects to the stitching, thus changing its direction. Simultaneously, the edge-locking device 2 is also sewing stitches around the corner of the mouse pad to achieve edge locking. After the mouse pad has changed direction, the edge-locking device 2 sews stitches around the other straight edge of the mouse pad to achieve edge locking. This process is repeated to complete the stitching of all four edges of the mouse pad to achieve edge locking. In other words, this invention can achieve continuous stitching of all four edges of the mouse pad to achieve edge locking in one go, eliminating the need for manual reversal of the mouse pad while the machine is stopped. This not only improves edge-locking efficiency but also reduces labor intensity, giving it a strong competitive edge in the market.

[0029] The workbench 1 is provided with a plurality of scrolling elements 11 to facilitate the movement of the mouse pad. The upper end of each scrolling element 11 protrudes beyond the upper surface of the workbench 1, forming a rolling contact surface. The mouse pad is placed on the rolling contact surface, minimizing friction between the mouse pad and the workbench, thus facilitating smoother movement of the mouse pad on the workbench. It is worth noting that the upper end of each scrolling element 11 only slightly protrudes beyond the upper surface of the workbench 1. The scrolling element 11 is either a ball bearing or a scroll wheel.

[0030] In order to enable the stitching of the mouse pad edge for edge locking, a guide strip 10 is provided on one side of the workbench 1 for guiding the edge of the mouse pad. The guide strip 10 is used to block the straight edge of the mouse pad that the auxiliary edge locking device 3 reverses, so that the straight edge of the mouse pad that needs to be stitched is pressed against the inner surface of the guide strip 10, so that the guide strip 10 plays a guiding role for the edge of the mouse pad, and the quality of the edge locking achieved by the subsequent stitching of the straight edge of the mouse pad placed on the workbench 1 by the edge locking device 2 is better.

[0031] The pressing component 31 is a buffer (such as a hydraulic buffer, spring buffer, etc.), and its end has a spring buffer head 311. The spring buffer head 311 presses down on the mouse pad, which achieves non-rigid contact. This not only protects the mouse pad, but also ensures the stability of the compression, and can press down on the mouse pad gently.

[0032] The rotary drive mechanism 33 includes a first motor 331 mounted on the bracket 4 and a rotating frame 333 mounted on the lower end of the rotating shaft 332 of the first motor 331. The lifting drive module 32 is fixedly connected to the rotating frame 333 and is not coaxial with the rotating shaft 332. The rotating shaft 332 is located directly above the sewing needle of the overlock device 2, so that the rotation axis of the rotary drive mechanism 33 is located directly above the part where the corner of the mouse pad is connected to the stitching. The structure of the entire rotary drive mechanism 33 is extremely simple.

[0033] The rotating frame 333 is L-shaped, and a coupling sleeve 334 is provided at the upper end of one side. The upper end of the coupling sleeve 334 is sleeved on the lower end of the rotating shaft 332 of the first motor 331. The first screw is horizontally screwed to the outer side of the upper end of the coupling sleeve 334, and the end of the first screw is locked and fixed to the outer side of the rotating shaft 332, so that the assembly structure of the rotating frame 333 and the rotating shaft 332 of the first motor 331 is extremely stable.

[0034] To enhance structural stability, the following design was also implemented: the bracket 4 is further provided with a support frame 41, which contains a bearing 42, and the bearing 42 is also fitted with a support shaft 43. The support shaft 43 is rotatable relative to the support frame 41. The support shaft 43 is fitted inside the lower end of the connecting sleeve 334, and a second screw is horizontally screwed to the outer side of the lower end of the connecting sleeve 334. The end of the second screw is engaged and fixed to the outer side of the support shaft 43. The support shaft 43 is coaxial with the rotating shaft 332 and rotates synchronously.

[0035] The lifting drive module 32 includes a first cylinder 321 fixed to the lower end of the rotating frame 333 and a first lifting frame 322 mounted on the upper end of the first cylinder 321 and driven by the first cylinder 321 to achieve lifting. The pressing member 31 is mounted on one side of the first lifting frame 322. The structure of the lifting drive module 32 is extremely simple.

[0036] A guide sleeve 323 is provided on the other side of the first lifting frame 322 opposite to the pressing member 31. The guide sleeve 323 is sleeved on the outside of the support shaft 43 and can slide up and down. The support shaft 43 is coaxially arranged with the rotating shaft 332 and rotates synchronously, thereby ensuring the stability of rotation and improving the stability of the entire first lifting frame 322 sliding up and down.

[0037] This utility model also includes a pressing and conveying device 5 for pressing down the mouse pad and driving the mouse pad to move in a straight line. The pressing and conveying device 5 is located next to the auxiliary edge locking device 3. The pressing and conveying device 5 is used to press down the mouse pad and drive the mouse pad to move in a straight line, and also plays the role of assisting in edge locking.

[0038] The pressing and conveying device 5 includes a lifting module 51 mounted on a bracket 4, a second lifting frame 52 mounted on the lower end of the lifting module 51 and driven by the lifting module 51 to achieve lifting and lowering, a second motor 53 mounted on the lower end of the second lifting frame 52, and a pressing and conveying wheel 54 connected to the second motor 53 and driven by the second motor 53 to achieve rotation. During operation, the lifting module 51 drives the second lifting frame 52 and the pressing and conveying wheel 54 to descend, causing the pressing and conveying wheel 54 to press onto the mouse pad. The second motor 53 then drives the pressing and conveying wheel 54 to rotate, thereby moving the mouse pad on the worktable to achieve stable sewing and overlocking.

[0039] In this embodiment, there are three pressing conveyor wheels 54 and two second motors 53. The first second motor 53 is a single-axis motor, and the first pressing conveyor wheel 54 is mounted on the rotating shaft of the single-axis motor. The second motor is a dual-axis motor, and the second and third pressing conveyor wheels 54 are respectively mounted on the two rotating shafts of the dual-axis motor. In other words, this utility model can press the mouse pad down with three pressing conveyor wheels 54 and drive the mouse pad to move on the worktable, thereby achieving the purpose of stable delivery of the mouse pad.

[0040] In summary, this invention enables continuous sewing of all four edges of a mouse pad in a single operation to achieve edge locking, eliminating the need for manual repositioning of the mouse pad while the machine is stopped. This not only improves edge locking efficiency but also reduces labor intensity, giving it a strong competitive edge in the market. Example 2:

[0041] The difference between this second embodiment and the first embodiment described above is that: [the following is a combination of...] Figure 5-6 As shown, in this second embodiment, the support shaft 43 is shortened, and a positioning pin 30 is fixed at the lower end of the guide sleeve 323. The positioning pin 30 is coaxially arranged with the support shaft 43. The advantage of this design is that the positioning pin 30 rises and falls with the pressing member 31, so as to better drive the mouse pad to rotate and achieve reversal. Specifically:

[0042] During operation, the edge-locking device 2 first sews a stitch along one straight edge of the mouse pad placed on the workbench 1 to achieve edge locking. When the edge-locking device 2 sews to or is about to sew to the corner of the mouse pad, the lifting drive module 32 in the auxiliary edge-locking device 3 drives the pressing member 31 to press down. The pressing member 31 presses down on the non-corner position of the mouse pad. At the same time, the positioning pin 30 presses down on the corner of the mouse pad, and the rotation drive mechanism 33 drives the lifting drive module 32 and the pressing member 31 to rotate, so that the edge of the mouse pad is locked. The pressing member 31 presses down on the mouse pad and drives it to rotate around the positioning pin 30 as the axis (instead of the part where the corner of the mouse pad connects to the seam as the axis in Embodiment 1), thereby changing its direction. At the same time, the edge-locking device 2 is also sewing the corner of the mouse pad to achieve edge locking. After the mouse pad has completed its direction change, the edge-locking device 2 sews the other straight edge of the mouse pad to achieve edge locking. This process is repeated to complete the sewing of all the outer edges of the mouse pad to achieve edge locking. In other words, this utility model can achieve continuous sewing of all four edges of the mouse pad to achieve edge locking in one go, without the need for manual reversal of the mouse pad when the machine is stopped. This not only improves edge locking efficiency but also reduces labor intensity, giving it a strong competitive edge in the market.

[0043] Apart from the above, the other structures of this second embodiment are the same as those of the first embodiment, and can achieve the same technical effects, which will not be described in detail here.

[0044] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
