Description

Technical Field

[0001] This utility model relates to carpet laser printing, and in particular to a positioning device for carpet laser printing. Background Technology

[0002] Carpets can generally have designed text and patterns printed on their surface through methods such as printing, spraying, embroidery, and laser printing. Laser printing typically uses specialized laser printing equipment, which generally includes a placement table for the carpet, a laser printing module, and a two-axis module that moves the laser printing module planarly. During laser printing, the two-axis module moves the laser printing module according to the designed text and patterns. Therefore, the positioning of the carpet on the placement table is crucial, determining whether the laser-printed text and patterns are in the designed positions. Currently, an L-shaped strip is typically placed on the placement table, and the carpet is placed on the table with one corner aligned with the L-shaped strip for positioning. When the carpet's positioning needs adjustment, the L-shaped strip is moved. However, this positioning method has a problem: the positioning is not stable enough. Utility Model Content

[0003] This application provides a positioning device for carpet laser printing, which can solve the problems mentioned in the background art.

[0004] This application provides a positioning device for carpet laser printing, comprising:

[0005] The first limiting bar is horizontal, with a sliding groove on the bottom surface and a waist-shaped groove on the top surface;

[0006] The connecting block includes: an upper block that is laterally slidably connected to the slide groove, and a lower block that extends beyond the bottom surface of the first limiting strip;

[0007] The bolt and nut are rectangular; the stud has a first vertical plane and passes through the connecting block and the waist-shaped groove in sequence.

[0008] Nut, a threaded connection to the portion of a bolt that protrudes from the slot;

[0009] The connector is connected to the first limiting strip and covers the waist-shaped groove in the lateral direction; it can also adjust its position in the longitudinal direction relative to the first limiting strip and switch between the following two states: contacting the first vertical plane to keep the nut in a lateral limiting state, and separating from the first vertical plane to allow the bolt to rotate in an unlimited state.

[0010] The second limiting bar is longitudinal; it is connected to the first limiting bar and is restricted from lateral movement.

[0011] In some embodiments, a set of elastic members is provided between the connector and the first limiting strip, the elastic members being used to keep the connector in a limited state.

[0012] In some embodiments, the stud also has a second vertical plane; the connector contacts the second vertical plane to keep the nut longitudinally aligned.

[0013] In some embodiments, the connector has an outer portion that retains the portion extending beyond the first limiting strip, and a second limiting strip is fixedly connected to the outer portion.

[0014] In some embodiments, the stud has a slot at the top, and the slot is oriented in the same direction as the nut.

[0015] In summary, this application discloses a positioning device for carpet laser printing, comprising a first limiting strip, a connecting block, a bolt, a nut, and a second limiting strip. The positioning device is installed in any one of the convex grooves in the placement platform. The carpet is placed on the placement platform, with its lateral edge abutting the vertical side of the first limiting strip and its longitudinal edge abutting the vertical side of the second limiting strip, thus completing the positioning. When the carpet's positioning needs adjustment, loosening the nut allows: 1. the first limiting strip, the second limiting strip, and the connecting block to move together longitudinally, thereby adjusting the carpet's position in the longitudinal direction; 2. the first limiting strip and the second limiting strip to move together laterally, thereby adjusting the carpet's position in the lateral direction; 3. when the lateral adjustment range is large, rotating the bolt switches the nut to longitudinal, allowing the positioning device to be removed upwards and installed in another suitable convex groove. The advantages include: more stable positioning, easier adjustment operations, and a simpler structure. Attached Figure Description

[0037] Please see Figure 1 , Figure 2 and Figure 3A positioning device for carpet laser printing includes a first limiting strip 1, a connecting block 2, a bolt 3, a nut 4, and a second limiting strip 6.

[0038] The carpet is placed on the placement table 7 of the laser printing equipment. The placement table 7 is provided with multiple parallel convex grooves 7a, and the convex grooves 7a are oriented longitudinally. The positioning device is installed in any one of the convex grooves 7a.

[0039] The first limiting bar 1 is horizontal, with a sliding groove 1a on the bottom surface and a waist-shaped groove 1b on the top surface.

[0040] Please see Figure 3 and Figure 5 The connecting block 2 includes an upper block 2a and a lower block 2b. The upper block 2a is slidably connected to the slide groove 1a in a transverse direction; more specifically, the width of the upper block 2a may be the same as the width of the slide groove 1a. The lower block 2b extends beyond the bottom surface of the first limiting strip 1. That is, when the positioning device is installed in the convex groove 7a, the bottom surface of the first limiting strip 1 is in contact with the placement platform 7, and the lower block 2b enters the narrower part of the convex groove 7a, with the width of the lower block 2b being the same as the width of the narrower part.

[0041] Please see Figure 1 The second limiting strip 6 is longitudinally connected to the first limiting strip 1 and is restricted from lateral movement. More specifically, the bottom surface of the first limiting strip 1 is also in contact with the placement surface 7.

[0042] In some embodiments, the connection between the second limiting strip 6 and the first limiting strip 1 can be a fixed connection.

[0043] With the platform 7 as a fixed reference object, the first limit bar 1 and the second limit bar 6 can move together laterally, and the first limit bar 1, the second limit bar 6, and the connecting block 2 can move together longitudinally.

[0044] Please see Figure 4 and Figure 7 The bottom of bolt 3 is a rectangular nut 3-1, and stud 3-2 passes through connecting block 2 and waist-shaped groove 1b. That is, when the positioning device is installed in convex groove 7a, the first limiting strip 1 is attached to the placement platform 7, and nut 3-1 is located in the wider part of convex groove 7a. When nut 3-1 and the first limiting strip 1 are both horizontal, the length of nut 3-1 is greater than the width of the narrower part, and bolt 3 cannot move upward away from convex groove 7a; when nut 3-1 and convex groove 7a are both vertical, the width of nut 3-1 is less than the width of the narrower part, and bolt 3 can move upward away from convex groove 7a.

[0045] Please see 2 and Figure 3Because the stud 3-2 passes through the waist-shaped groove 1b, when the first limiting strip 1 and the second limiting strip 6 move laterally together, the lateral movement range of the first limiting strip 1 is limited by the waist-shaped groove 1b. Based on the distance between two adjacent convex grooves 7a, the lateral length of the waist-shaped groove 1b is designed to be greater than the distance.

[0046] Please see Figure 6 The connector 5 is connected to the first limiting strip 1 and can also adjust its position longitudinally relative to the first limiting strip 1.

[0047] In some embodiments, the position adjustment of the connector 5 can be achieved by: setting a screw on the connector 5 and setting a matching screw nut 4 on the first limiting strip 1; the relative rotation of the screw and the screw nut 4 can drive the connector 5 to move longitudinally relative to the first limiting strip 1.

[0048] The connector 5 covers the waist-shaped groove 1b in the lateral direction. That is, based on the length of the waist-shaped groove 1b in the lateral direction, the length of the connector 5 in the lateral direction and the installation position of the connector 5 in the first limiting strip 1 are designed so that when the first limiting strip 1 moves alone in the lateral direction, the bolt 3 can remain corresponding to the connector 5.

[0049] Please see Figure 3 and Figure 8 The stud 3-2 also has a first vertical plane 3-2a. More specifically, a notch is cut into the stud 3-2 to form the first vertical plane 3-2a. The connector 5 switches between two states by adjusting its position relative to the first limiting strip 1 along the longitudinal direction: contacting the first vertical plane 3-2a to keep the nut 3-1 in a lateral limiting state, and separating from the first vertical plane 3-2a to allow the bolt 3 to rotate in an unlimited state. That is to say, the connector 5 covers the waist-shaped groove 1b laterally so that the connector 5 can maintain the limiting state when the first limiting strip 1 moves laterally.

[0050] Please see Figure 5 and Figure 6 In some embodiments, the position adjustment of the connector 5 can be achieved by providing a set of elastic elements 8 between the connector 5 and the first limiting strip 1. Under the action of the elastic elements 8, the connector 5 contacts the first vertical plane 3-2a, keeping the connector 5 in a limited state. By manually overcoming the elastic elements 8, the connector 5 can be moved longitudinally relative to the first limiting strip 1.

[0051] More specifically, the elastic element 8 can be a compression spring, and the first limiting strip 1 also has a mounting groove 1c that connects to the sliding groove 1a. Two longitudinal sleeves 1d are fixedly connected in the mounting groove 1c by screws. The connecting piece 5 allows the sleeves 1d to pass through, and there are two compression springs, which are respectively sleeved on the two sleeves 1d. Compared with setting a screw and screw nut 4, using the elastic element 8 results in a simpler structure and is more convenient to install.

[0052] Please see Figure 7 The nut 4 is threaded onto the part of the stud 3-2 that protrudes from the waist-shaped groove 1b. That is, the thickness of the lower block 2b is less than the thickness of the narrower part, so that the nut 3-1 can fit into the stepped surface of the convex groove 7a.

[0053] Installation of the positioning device and the convex groove 7a: When the connector 5 is in an unlimited state, rotate the bolt 3 to adjust the nut 3-1 to the longitudinal direction; insert the nut 3-1 into the convex groove 7a, rotate the bolt 3 to switch the nut 3-1 to the transverse direction; switch the connector 5 to the limited state, tighten the nut 4 so that the nut 4 abuts against the top surface of the first limiting strip 1, and the nut 3-1 abuts against the step surface of the convex groove 7a, thereby squeezing and generating friction, and fixing the first limiting strip 1 to the placement platform 7.

[0054] Please see Figure 6 In some embodiments, based on the above embodiment of "a set of elastic members 8 is provided between the connecting member 5 and the first limiting strip 1", the connection method between the second limiting strip 6 and the first limiting strip 1 can also be: the connecting member 5 has an outer portion that is held to extend out of the first limiting strip 1, and the second limiting strip 6 is fixedly connected to the outer portion.

[0055] During the tightening of bolt 3, one hand can hold the second limiting strip 6 to keep the connecting piece 5 more stably in the limiting state.

[0056] Please see Figure 9 In some embodiments, the stud 3-2 also has a second vertical plane 3-2b. More specifically, considering the possibility of having two vertical planes, which may affect the threaded connection between the nut 4 and the stud 3-2, the stud 3-2 can be composed of a threaded portion with a smaller diameter and a smooth portion with a larger diameter. Both the first vertical plane 3-2a and the second vertical plane 3-2b are located on the smooth portion. The contact between the connector 5 and the second vertical plane 3-2b keeps the nut 3-1 longitudinally aligned.

[0057] After rotating bolt 3 to adjust nut 3-1 to the longitudinal direction, connector 5 and second vertical plane 3-2b are brought into contact. Nut 3-1 remains longitudinal, making it easier to insert nut 3-1 into convex groove 7a.

[0058] Please see Figure 9 In some embodiments, the top of the stud 3-2 has a slot 3-2c, and the orientation of the slot 3-2c is the same as that of the nut 3-1.

[0059] The orientation of nut 3-1 can be easily determined by using the slot 3-2c.

[0060] Please see Figure 1The carpet 9 is placed on the placement table 7, with its horizontal edge attached to the vertical side of the first limiting strip 1 and its vertical edge attached to the vertical side of the second limiting strip 6, thus completing the positioning.

[0061] When the positioning of carpet 9 needs to be adjusted, loosen nut 4: 1. First limit strip 1, second limit strip 6, and connecting block 2 can move together longitudinally to adjust the position of carpet 9 in the longitudinal direction; 2. First limit strip 1 and second limit strip 6 can move together transversely to adjust the position of carpet 9 in the transverse direction; 3. When the transverse adjustment range is relatively large, turn bolt 3 to switch nut 3-1 to longitudinal direction, remove the positioning device upwards, and select another suitable convex groove 7a for installation.
