Description

Technical Field

[0001] The utility model relates to the technical field of plate splicing clamps, in particular to a plate splicing clamp. Background Art

[0002] PET is a polyester plastic, mainly made from the reaction of ethylene glycol and terephthalic acid. In the process of making PET sheets, it may be necessary to splice multiple PET sheets together to form a large area of ​​material, and special clamps are needed to fix the PET sheets.

[0003] In order to ensure the quality and accuracy of PET sheet splicing, it is necessary to clamp and fix the sheet with the help of a splicing clamp. For example, the prior art Chinese patent publication number "CN215660775U" discloses a fastening clamping device for sheet splicing, which is characterized in that it includes two "C"-shaped clamping seats, one end of the clamping seat located at the top is screwed with a threaded push rod, and the lower end of the threaded push rod is provided with a clamping head. The two clamping seats are placed in parallel and connected by parallel guide rods and threaded pull rods. One clamping seat is fixedly connected to one end of the guide rod, and the other clamping seat is movably connected to the guide rod through a light hole and can slide along the guide rod. The threaded pull rod is rotatably fixedly connected to one clamping seat and screwed to the other clamping seat through a threaded hole.

[0004] Some splicing clamps drive a pair of clamping heads to tighten the plates by rotating a handle, but in actual operation, similar clamps control the pressure of the clamping heads on the plates by manually rotating the handle. The pressure on the plates can only be controlled by manual feel, and the different pressures of different plates cannot be accurately controlled. When the force is not appropriate, the plates may be too tight or too loose, which may cause damage to the plates or poor quality of the plate splicing. Utility Model Content

[0023] Furthermore, the driving assembly 5 includes a motor 51, which is fixedly mounted on the top of the support seat 2. The shaft end of the motor 51 passes through the support seat 2 and is fixedly connected to a first rotating rod 52. The end of the first rotating rod 52 is located in the mounting groove 21 and is fixedly mounted with a first bevel gear 53. Another second rotating rod 54 is rotatably connected in the mounting groove 21 of the support seat 2, and the shaft end of the second rotating rod 54 is fixedly mounted with the first bevel gear 53.

[0024] Furthermore, a round rod 55 is provided between a pair of the support seats 2, and both ends of the round rod 55 pass through the support seats 2 and are fixedly installed with a second bevel gear 56 in the mounting groove 21. The second bevel gear 56 meshes and rotates with the first bevel gear 53, and the first rotating rod 52 and the second rotating rod 54 are driven simultaneously by the motor 51, ensuring that the two rotating rods are driven by the same pressure, thereby ensuring that the same pressing force can be applied to both ends of the plate.

[0025] In more detail, the first rotating rod 52 and the second rotating rod 54 are threaded rods and are threadedly connected to the cross plate 4. Straight rods 7 are slidably connected to both sides of the cross plate 4. A pressure block 71 is fixedly installed on the other end of the straight rod 7. A first spring 72 is sleeved on the outer periphery of the straight rod 7. The two ends of the first spring 72 are respectively fixedly connected to the bottom surface of the cross plate 4 and the top of the pressure block 71. The pressure block 71 is used to press and fix the plate. The first spring 72 plays a role of buffering and shock absorption to prevent the pressure block 71 from applying excessive pressing force to the plate.

[0026] In general, the limiting assembly 6 includes a straight plate 61, a first guide groove 62 and a second guide groove 63 are formed in the straight plate 61, a rack 65 is fixedly installed in the first guide groove 62, and a straight plate 61 has a straight groove 64, and the straight groove 64 runs through the straight plate 61 and the rack 65.

[0027] Finally, a claw 66 is longitudinally slidably connected in the first guide groove 62 and the second guide groove 63, and the claw 66 is transversely slidably connected in the one-shaped groove 64. A second spring 67 is sleeved on the axial end of the claw 66 in the second guide groove 63. One end of the second spring 67 is in contact with the end surface of the second guide groove 63, and the other end is fixedly connected to the axial end of the claw 66. The claw 66 can be engaged with the teeth of the rack 65. The teeth of the claw 66 are in an M-shaped structure, which can better engage and lock with the rack 65. When the claw 66 is pushed, it can be moved in the one-shaped groove 64, and then the rack 65 continues to engage the claw 66 under the action of the second spring 67.

[0028] In addition, a wedge block 41 is fixedly installed on one side of the cross plate 4, and a button 661 is provided at one end of the claw 66. The button 661 is electrically connected to the motor 51. When the cross plate 4 moves, the wedge block 41 can contact and press the button 661. When the cross plate 4 drives the wedge block 41 to move to a suitable position, the wedge block 41 contacts and presses the button 661, so that the motor 51 stops driving to control the pressure block 71 to clamp and fix the plate with different forces, and the position of the button 661 can be changed by clamping the claw 66 by the rack 65.

[0029] Working mode: When working, the plate is placed on the end face of the support seat 2, and the motor 51 drives the first bevel gear 53 and the first rotating rod 52 to rotate, and the first bevel gear 53 drives the round rod 55 through the second bevel gear 56 on one side to drive the second bevel gear 56 on the other side, so that the cross plate 4 is subjected to the same movement drive on the two rotating rods, and the same pressing force is applied to both ends of the plate to ensure the splicing accuracy of the plate, and the claw 66 is pushed to disengage the claw from the teeth of the rack 65. After the claw 66 moves to the appropriate position, it returns to its original position under the action of the second spring 67, and the rack 65 continues to clamp the claw 66. When the cross plate 4 drives the wedge block 41 to contact the pressing button 661, the motor 51 stops driving, and the pressing block 71 is changed to apply different pressing forces to the plate.
