Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a single-arm hot melt adhesive machine sliding arm anti-collision protective device. Background Art

[0002] The single-arm hot melt glue machine is a device that uses a single sliding arm to pull the glue dispensing mechanism and spray glue onto the fabric on the operating table. The single-arm hot melt glue machine drives the sliding arm to move through the sliding table. One end of the sliding arm is fixed on the slider, and the other end is installed with the glue spraying mechanism. Due to the long length of the sliding arm, the end of the sliding arm fixed to the slider is short, and the end of the sliding arm suspended is long, forming a lever structure, so the weight is uneven. After the sliding arm accidentally collides with the equipment on the workbench or the operators around the workbench, the end of the sliding arm fixed to the slider is easily damaged by the collision. Frequent maintenance wastes a lot of production and processing time. Therefore, a new type of single-arm hot melt glue machine sliding arm anti-collision protection device is proposed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a single-arm hot melt glue machine sliding arm anti-collision protection device, which is used to solve the problem that the existing single-arm hot melt glue machine sliding arm is too long and easily damaged by the end fixed to the slider after accidentally colliding with equipment on the workbench or operators around the workbench.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A single-arm hot melt adhesive machine sliding arm anti-collision protection device comprises a long hollow fixed groove plate fixedly installed on the top of a sliding block slidably connected to a frame, a fixed plate is arranged above the fixed groove plate, a sliding arm is fixedly installed on the fixed plate, a plurality of arched limit frames perpendicular to the fixed groove plate are fixedly connected to the bottom of the inner wall of the fixed groove plate at equal distances along the length direction, buffer springs are fixedly installed horizontally on both sides of the inner wall of the limit frame, a plurality of clamping blocks are fixedly connected to the bottom of the fixed plate at equal distances along the length direction, the clamping block is movably clamped between two buffer springs, and one end of the fixed groove plate is threadedly connected to a positioning screw for supporting the fixed clamping block.

[0006] Preferably, one end of the positioning screw is fixedly connected to a hand wheel.

[0007] Preferably, both sides of the fixed slot plate are fixedly connected with stop frames located on both sides of the sliding arm.

[0008] Preferably, at least two groups of the sliding blocks are arranged along the length direction of the sliding arm.

[0009] Preferably, the fixing plate is fixed to the sliding arm by bolts.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model provides a fixed groove plate on the slider to cooperate with the fixed plate, and buffer springs are arranged on both sides of the clamping block below the fixed plate. When the longer slide arm above the fixed plate is hit, the fixed plate and the fixed groove plate are driven to move left or right, and they will contact and squeeze the buffer spring. The buffer spring contracts to achieve buffering and giving way, and then generates a reverse elastic force to reset the slide arm, thereby realizing anti-collision protection for the slide arm, greatly reducing the phenomenon of damage to the slide arm due to accidental collision, and solving the problem that the slide arm of the existing single-arm hot melt adhesive machine is long and the end fixed to the slide block is easily damaged after accidentally colliding with equipment on the workbench or operators around the workbench.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-5 As shown, the utility model provides a technical solution: a single-arm hot melt adhesive machine slide arm anti-collision protection device, comprising a long strip hollow fixed groove plate 3 fixedly installed on the top of a slide block 2 slidably connected to a frame 1, the slide block 2 is provided with at least two groups along the length direction of the slide arm 7, a fixed plate 4 is provided above the fixed groove plate 3, a slide arm 7 is fixedly installed on the fixed plate 4, and the slide arm 7 is fixedly installed on the fixed plate 4 by bolts;

[0020] A plurality of bow-shaped limit frames 301 perpendicular to the fixed slot plate 3 are fixedly connected to the bottom of the inner wall of the fixed slot plate 3 at equal intervals along the length direction, and buffer springs 302 are horizontally fixedly installed on both sides of the inner wall of the limit frame 301. A plurality of clamping blocks 401 are fixedly connected to the bottom of the fixed plate 4 at equal intervals along the length direction, and the clamping block 401 is movably clamped between two buffer springs 302. A positioning screw 5 for supporting the fixed clamping block 401 is threadedly connected to one end of the fixed slot plate 3, and a hand wheel 501 is fixedly connected to one end of the positioning screw 5. Stop frames 6 located on both sides of the sliding arm 7 are fixedly connected to both sides of the fixed slot plate 3.
