As shown in fig. 1-4 and 6:

a palm folding and abrasion preventing device of a palm folding machine for label production comprises a bottom plate 1, two sliding rails 1a are fixedly arranged on the bottom plate 1, the two sliding rails 1a are symmetrically arranged relative to the axis of the bottom plate 1, and the palm folding and abrasion preventing device further comprises a pressing assembly 2, a fixing assembly 3 and a driving assembly 4; the pressing assemblies 2 are multiple, each fixing assembly 3 comprises a sliding block 3a, a plurality of movable limiting blocks 3b, a first elastic part 3c and a limiting groove 3d, the sliding blocks 3a are multiple, the sliding blocks 3a are symmetrically and slidably mounted on the two sliding rails 1a, each pressing assembly 2 is mounted on the corresponding sliding block 3a, the two movable limiting blocks 3b are slidably mounted on each sliding block 3a, the bottom of each movable limiting block 3b is provided with a fillet, the first elastic parts 3c are multiple and located between the corresponding sliding blocks 3a and the corresponding movable limiting blocks 3b, two ends of each first elastic part 3c are fixedly connected with the corresponding sliding block 3a and the corresponding movable limiting block 3b respectively, the limiting grooves 3d are multiple and located at the corresponding sliding rails 1a, and two limiting grooves 3d are formed in each sliding rail 1 a; the driving assembly 4 is provided in plurality, and one driving assembly 4 is mounted on each slide block 3a for driving the first elastic member 3c to slide.

Based on the above embodiments, the technical problem to be solved by the present application is how to speed up the installation and adjustment of the hold-down assembly 2. Therefore, the function of the palm folding abrasion-proof device of the palm folding machine can be quickly assembled, disassembled and adjusted through the bottom plate 1, the pressing assembly 2, the fixing assembly 3 and the driving assembly 4. When an operator installs the pressing assembly 2, the sliding block 3a is installed on the sliding rail 1a until the movable limiting block 3b moves to the position of the limiting groove 3d, the movable limiting block 3b is driven by the driving assembly 4 to slide towards the outer side of the sliding block 3a and enter the limiting groove 3d, and the friction force between the movable limiting block 3b and the limiting groove 3d is enhanced through the driving force of the driving assembly 4, so that the sliding block 3a is fixed on the sliding rail 1 a; when an operator needs to adjust the position of the pressing assembly 2 or detach the pressing assembly 2, the driving of the driving assembly 4 is stopped, the movable limiting block 3b is driven by the elasticity of the first elastic piece 3c to move into the sliding block 3a, and the sliding block 3a is taken out of the sliding rail 1 a.

Further, in order to solve the technical problem of how to drive the movable limiting block 3b to slide against the resistance of the first elastic member 3c, as shown in fig. 5:

the driving assembly 4 comprises a lifting block 4a and a wedge strip 4b, the lifting block 4a is slidably mounted on the sliding block 3a, and the wedge strip 4b is fixedly arranged at the bottom of the lifting block 4 a.

Based on the above-mentioned embodiment, the technical problem that the present application intends to solve is how to drive the movable stopper 3b to slide outward against the resistance of the first elastic member 3 c. Therefore, the lifting block 4a and the wedge strip 4b have the function that the wedge strip 4b overcomes the elasticity of the first elastic piece 3c to extrude the two movable limiting blocks 3b out of the sliding block 3a and support the movable limiting blocks 3 b. When an operator installs the pressing assembly 2, the sliding block 3a is installed on the sliding rail 1a until the movable limiting block 3b moves to the position of the limiting groove 3d, and then the lifting block 4a is pressed, so that the movable limiting block 3b is extruded by the wedge strip 4b at the bottom of the lifting block 4a, the movable limiting block 3b slides towards the outer side of the sliding block 3a and enters the limiting groove 3d, and the friction force between the movable limiting block 3b and the limiting groove 3d is enhanced through the support of the wedge strip 4b, so that the sliding block 3a is fixed on the sliding rail 1 a; when an operator needs to adjust the position of the pressing assembly 2 or detach the pressing assembly 2, the lifting block 4a is pulled upwards, so that the wedge strip 4b stops supporting the movable limiting block 3b, the movable limiting block 3b is driven to move into the sliding block 3a through the elasticity of the first elastic piece 3c, and the sliding block 3a is taken out of the sliding rail 1 a.

Further, the compressing assembly 2 provided by the present application still has a defect that the processed film material after the startup of the hand-closing machine continuously generates sliding friction with the compressing assembly 2, so that the compressing assembly 2 is seriously worn, and in order to solve this problem, as shown in fig. 2 and fig. 9:

the pressing assembly 2 comprises a rotating shaft 2a and a guide roller 2b, two ends of the rotating shaft 2a are respectively rotatably arranged on two sliding blocks 3a, and the guide roller 2b is sleeved on the rotating shaft 2 a.

Based on the above embodiments, the technical problem that the present application intends to solve is how to slow down the wear of the hold-down assembly 2. For this reason, the present application achieves the function of slowing down the wear of the hold-down assembly 2 by rolling instead of sliding, by means of the rotating shaft 2a and the guide roller 2 b. When an operator adjusts the pressing assemblies 2 to proper positions through the pressing assemblies 2, the fixing assemblies 3 and the driving assemblies 4, the palm closing machine is started, the film material is compacted through the guide rollers 2b, and the guide rollers 2b rotate around the rotating shafts 2a under the action of friction force along with the movement of the film material, so that the guide rollers 2b are prevented from being seriously abraded due to sliding friction between the guide rollers 2b and the film material.

Further, the driving assembly 4 provided by the present application still has a defect that the sliding block 3a is mounted on the sliding rail 1a each time, the lifting block 4a needs to be manually pressed, and if an operator forgets to press the lifting block 4a, the machine is directly started, which may cause the pressing assembly 2 to shift or fall off, in order to solve the problem, as shown in fig. 6 and 8:

the driving assembly 4 further comprises a second elastic member 4c, and two ends of the second elastic member 4c are respectively fixedly connected with the sliding block 3a and the lifting block 4 a.

Based on the above embodiments, the technical problem that the present application intends to solve is how to prevent the situation that the operator mistakenly operates to cause the fixed component 3 not to fix the position of the sliding block 3a when installing the pressing component 2. For this reason, the present application realizes the function of driving the pull-up block 4a to move downward by the elastic force of the second elastic member 4 c. When the sliding block 3a is not affected by the outside, the lifting block 4a moves downwards under the influence of the elasticity of the second elastic piece 4c, so that the movable limiting block 3b is extruded by the wedge strip 4b, and the movable limiting block 3b is positioned outside the sliding block 3 a; when the operator installs the compressing component 2, the lifting block 4a is pulled upwards against the elasticity of the second elastic piece 4c, then the movable limiting block 3b is pulled by the elasticity of the first elastic piece 3c to enable the movable limiting block 3b to slide into the sliding block 3a, then the sliding block 3a is arranged on the sliding rail 1a until the movable limiting block 3b moves to the position of the limiting groove 3d, the lifting block 4a is loosened, after the lifting block 4a loses the external force support, the lifting block 4a is driven to move downwards by the elasticity of the second elastic piece 4c, thereby the movable limiting block 3b is extruded by the wedge strip 4b at the bottom of the lifting block 4a, the movable limiting block 3b slides to the outer side of the slide block 3a and enters the limiting groove 3d, the friction force between the movable limiting block 3b and the limiting groove 3d is enhanced through the support of the wedge strip 4b, so that the sliding block 3a is fixed on the sliding rail 1 a; when an operator needs to adjust the position of the pressing assembly 2 or detach the pressing assembly 2, the lifting block 4a is pulled upwards, so that the wedge strip 4b stops supporting the movable limiting block 3b, the movable limiting block 3b is driven to move into the sliding block 3a through the elasticity of the first elastic piece 3c, and the sliding block 3a is taken out of the sliding rail 1 a.

Further, when the fixing assembly 3 still has the installation sliding block 3a, the sliding block 3a needs to be manually installed on the sliding rail 1a by an operator, but the operator may loosen the sliding block 3a without installing the sliding block 3a in place, which results in a defect that the fixing assembly 3 cannot fix the pressing assembly 2, and in order to solve the problem, as shown in fig. 3, 4 and 6:

For this reason, this application has realized the function of reinforcing activity stopper 3b surface frictional property through slipmat 3b 1. Through evenly setting up unevenness's non-slip texture on slipmat 3b1, increase slipmat 3b 1's roughness to reinforcing the frictional force between slipmat 3b1 and the slide rail 1a lateral wall, thereby strengthening movable stopper 3 b's non-slip performance, and design into flexible material with slipmat 3b 1's material, reduced the wearing and tearing between slide rail 1a and the slipmat 3b 1.

Further, when the wedge strip 4b provided by the present application still has the movable limiting block 3b, the movable limiting block 3b has a large resistance to the wedge strip 4b, and in order to solve the problem, as shown in fig. 5:

the bottom of the wedge strip 4b is fixedly provided with a guide angle 4d, and the guide angle 4d is arc-shaped.

Based on the above embodiments, the technical problem that the present application intends to solve is how to slow down the wear rate of the wedge 4b and the movable stopper 3 b.
