[0002] Foam plastic processing refers to the process of making foam plastic products with specific shapes, properties and uses through a series of processes. Foam plastic is a lightweight, porous plastic material with good heat insulation, sound absorption, cushioning and buoyancy properties. It is widely used in packaging, construction, transportation, furniture, sporting goods and other fields.

[0003] During the processing of foam plastics, the foam plastics need to be clamped to achieve fixation and displacement of the foam plastics. For foam plastics of different thicknesses, clamping mechanisms of corresponding sizes are generally required to maintain the clamping effect, which means that it is not convenient to make a certain degree of adjustment according to the size range of the foam parts to be clamped, which is inconvenient to use. In addition, the surface of the foam plastics is soft and easy to deform, so clamping marks are likely to appear during the clamping process, thereby affecting the appearance of the foam plastics. Utility Model Content

[0004] The utility model aims to provide a clamping device for foam plastic processing, so as to solve the technical problems in the prior art that the same clamping device has poor adaptability to foam plastics of different thicknesses and is prone to produce clamping marks.

[0005] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0006] A clamping device for foam plastic processing, comprising a motor, a transmission threaded rod fixedly connected to the output end of the motor, and guard plates fixedly connected to both sides of the motor. The device also includes an adjusting mechanism, a connecting mechanism and a pressure detection mechanism. The adjusting mechanism includes two groups of observation boxes respectively fixedly connected to the corresponding guard plates, and the adjusting threaded rod is rotatably connected inside the observation box; the connecting mechanism is provided with two groups, and the two groups of the connecting mechanisms are mirror-matched and arranged between the two groups of adjusting threaded rods, and a clamping arm is rotatably arranged on each group of the connecting mechanisms; the pressure detection mechanism includes a threaded block threadedly connected to the transmission threaded rod, elastic detection components are symmetrically arranged on both sides of the threaded block, a ball is arranged at one end of the elastic detection component away from the threaded block, a roller is cooperated with one side of the ball, the two groups of the clamping arms are respectively arranged between the corresponding ball and the roller, and the clamping arms are movably hinged with a clamping plate at one end away from the connecting mechanism.

[0008] As a further solution of the utility model: the elastic detection component includes a guide column fixedly connected to the threaded block, the guide column is fixedly connected to a detection plate at one end away from the threaded block, a measuring spring and a sliding sleeve are slidably sleeved on the outer side of the guide column in sequence, the measuring spring is fixedly arranged between the detection plate and the sliding sleeve, a second observation port is opened on one side of the sliding sleeve, the pressure range is marked on one side of the second observation port, and the second observation port cooperates with the detection plate.

[0009] As a further solution of the utility model: each group of the sliding sleeves is fixedly connected to a partition, and each group of the partitions is fixedly connected to a pressure spring on the side away from the detection plate.

[0012] Beneficial effects of the utility model:

[0013] 1. The utility model drives the adjusting threaded rod to rotate by rotating the adjusting knob, thereby driving the two sets of hinge blocks to move away from or closer to each other, and then adjusting the minimum spacing after clamping by the clamping end of the clamping arm, that is, the larger the spacing between the two sets of hinge blocks, the smaller the minimum spacing after clamping by the clamping end of the clamping arm, and the smaller the thickness of the clampable foam plastic plate adapted thereto, so as to achieve the effect of being able to adapt to a variety of foam plastics of different thicknesses through debugging.

DETAILED DESCRIPTION

[0021] 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 of 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.

[0022] like Figure 1-Figure 4As shown, a clamping device for foam plastic processing includes a motor 1, a transmission threaded rod 2 is fixedly connected to the output end of the motor 1, and guard plates 3 are fixedly connected to both sides of the motor 1. The device also includes an adjusting mechanism 4, a connecting mechanism 5 and a pressure detection mechanism 7. The adjusting mechanism 4 includes two groups of observation boxes 401 respectively fixedly connected to the corresponding guard plates 3, and the inside of the observation box 401 is rotatably connected with an adjusting threaded rod 403; the connecting mechanism 5 is provided with two groups, and the two groups of connecting mechanisms 5 are mirror-matched and arranged between the two groups of adjusting threaded rods 403, and the positions of the two groups of connecting mechanisms 5 can be adjusted by adjusting the threaded rods 403, and a clamping arm 6 is rotatably arranged on each group of connecting mechanisms 5; the pressure detection mechanism 7 includes a threaded block 701 threadedly connected to the transmission threaded rod 2, and elastic detection components are symmetrically arranged on both sides of the threaded block 701, and the elastic detection components are responsible for detecting the force applied to the clamping arm 6, and the elastic detection component is provided at one end away from the threaded block 701. The ball 707 is provided with a roller 708 on one side of the ball 707. The two groups of clamping arms 6 are respectively arranged between the corresponding ball 707 and the roller 708, and the clamping arm 6 is movably hinged with a clamping plate 9 at one end away from the connecting mechanism 5. The ball 707 and the roller 708 are responsible for clamping and limiting the clamping arm 6. The starting motor 1 drives the transmission threaded rod 2 to rotate, and the transmission threaded rod 2 drives the threaded block 701 to move forward and backward, driving the clamping arm 6 to rotate around the connecting mechanism 5, thereby realizing the clamping operation of the clamping arm 6. By adjusting the threaded rod 403, the position of the connecting end of the clamping arm 6 is adjusted, and then the clamping end of the clamping arm 6 and the minimum spacing after clamping are adjusted. After the clamping arm 6 clamps the foam plastic, the foam plastic will squeeze the clamping arm 6 in the opposite direction. By observing the elastic detection component, the clamping force is judged, which is convenient for subsequent targeted adjustment, data recording and unified processing of the clamping device.

[0023] In some specific embodiments, in order to achieve seamless clamping of foam plastics of various thicknesses, each group of connecting mechanisms 5 includes an articulated block 501, and the two articulated blocks 501 of the two groups of connecting mechanisms 5 are both movably articulated with the corresponding clamping arms 6 on the sides away from each other. The articulated blocks 501 are fixedly connected with through plates 502 on both sides, and the through plates 502 are threadedly connected with the corresponding adjusting threaded rods 403. The adjusting threaded rods 403 are provided with upper and lower sections of threads, and the two sections of threads are in opposite directions. The top of each group of adjusting threaded rods 403 is fixedly connected with an adjusting knob 402, and a first observation port 404 is provided on one side of the observation box 401. An adjustment range is marked on one side of the first observation port 404, and the spacing of the articulated blocks 501 is calculated by comparing the adjustment range; the adjustment knob 402 is rotated to drive the adjustment threaded rod 403 to rotate, thereby driving the two groups of articulated blocks 501 to move away from or closer to each other, and then adjusting the minimum spacing after clamping by the clamping end of the clamping arm 6, that is, the larger the spacing between the two groups of articulated blocks 501, the smaller the minimum spacing after clamping by the clamping end of the clamping arm 6, and the smaller the thickness of the foam plastic board that can be clamped accordingly. The most suitable spacing of the articulated blocks 501 is obtained through debugging and applied to other clamping devices, saving the time of re-debugging and improving the debugging efficiency.

[0024] In some specific implementation schemes, in order to more conveniently determine the clamping force and facilitate debugging by the debugging personnel, the elastic detection component includes a guide column 702 fixedly connected to the threaded block 701, and the end of the guide column 702 away from the threaded block 701 is fixedly connected to the detection plate 703, and the outer side of the guide column 702 is slidably sleeved with a measuring spring 704 and a sliding sleeve 705 in sequence. The measuring spring 704 is fixedly arranged between the detection plate 703 and the sliding sleeve 705. The measuring spring 704 has a strong elastic strength, and a second Observation port 710, the second observation port 710 is longitudinally distributed on one side of the sliding sleeve 705, and the pressure range is marked on one side of the second observation port 710. The pressure range is divided into three parts, corresponding to the three clamping strengths of weak, medium and strong. The second observation port 710 is matched with the detection plate 703, and the detection plate 703 is painted with bright colors to facilitate observation during the debugging process; during the debugging process, the debugger will constantly adjust the spacing between the two sets of hinge blocks 501 and conduct a clamping experiment. When the clamping arm 6 is clamped, the foam plastic will cause the clamping arm 6 to reverse. The clamping arm 6 is subjected to force, and the clamping arm 6 squeezes the roller 708. The roller 708 drives the sliding sleeve 705 to move along the guide column 702. At this time, the guide column 702 and the detection plate 703 are stationary relative to the threaded block 701, and the sliding sleeve 705 is moving relative to the guide column 702 and the detection plate 703. The pressure range on one side of the sliding sleeve 705 will move relative to the detection plate 703 along with the sliding sleeve 705. The sliding sleeve 705 will squeeze the measuring spring 704 between the detection plate 703, and the greater the pressure, the greater the deformation of the measuring spring 704. The pressure range corresponding to the position of the detection plate 703 is observed through the second observation port 710 to determine the force applied to the measuring spring 704. At the same time, the measuring spring 704 can also be used as a pressure buffer component to reduce damage to the foam plastic during the clamping process. It should be noted that since the direction of the reaction force given by the foam plastic to the corresponding clamping arm 6 is unchanged, and the device only needs to measure the reaction force of the clamping arm 6, the clamping arm 6 will only generate a tensile force on the pressure detection mechanism 7 during the clamping process, and no extrusion force will be generated.

[0025] In some specific implementation schemes, in order to adapt to the state changes of the clamping arm 6 and ensure the smooth progress of the clamping operation, each set of sliding sleeves 705 is fixedly connected with a partition 709, and each set of partitions 709 is fixedly connected with a pressure spring 706 on the side away from the detection plate 703. The pressure spring 706 is fixedly connected with a bead shell on the end away from the partition 709. The bead shell and the corresponding ball 707 are rotatably arranged to ensure that the ball 707 can still roll while the pressure spring 706 squeezes the ball 707 upward. The ball 707 is rotatably arranged on the end of the sliding sleeve 705 away from the threaded block 701. In the process of the transmission threaded rod 2 driving the threaded block 701 to move forward and backward, the clamping arm 6 located between the ball 707 and the roller 708 will undergo a certain The tilted state will squeeze the ball 707 and the roller 708, causing the ball 707 to move downward, thereby adapting to the state change of the clamping arm 6 and ensuring the smooth progress of the clamping operation. It should be noted that the pressure spring 706 and the measuring spring 704 have different implementation objects. When the pressure detection mechanism 7 moves along the transmission threaded rod 2, the compression degree of the pressure spring 706 will change with the change of the tilt angle of the clamping arm 6, while the measuring spring 704 will not be compressed. When the clamping plate 9 clamps the foam plastic, the clamping arm 6 will lift the sleeve 705, so that the measuring spring 704 located between the sleeve 705 and the detection plate 703 is compressed, and at this time, the compression degree of the pressure spring 706 still depends on the tilt angle of the clamping arm 6.

[0026] In some specific implementation schemes, in order to ensure the stability of the transmission component during implementation and extend its service life, an outer frame 8 is fixedly connected to one side of the observation box 401, and glass plates are fixedly installed on both sides of the outer frame 8 to facilitate the debugging personnel to observe the elasticity detection component. The pressure detection mechanism 7 and the transmission threaded rod 2 are both arranged inside the outer frame 8; the outer frame 8 is responsible for protecting the internal components and reducing the impact of external dust, waste, foam plastic blocks and other objects on the internal components of the outer frame 8.

[0027] In some specific embodiments, in order to improve the stability of the foam plastic during clamping or transportation, two sets of clamping plates 9 are fixedly connected to adjacent surfaces with flexible pads, which may be rubber pads or elastic foams; the two sets of clamping arms 6 are clamped by the clamping plates 9, and the flexible pads are responsible for increasing the friction coefficient with the foam plastic to ensure stability during clamping or transportation.

[0028] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0029] When the foam plastic needs to be clamped, the motor 1 is started to drive the transmission threaded rod 2 to rotate, and the transmission threaded rod 2 drives the threaded block 701 to move forward and backward, and drives the clamping arm 6 to rotate around the connecting mechanism 5, thereby realizing the clamping operation of the clamping arm 6. The adjusting knob 402 is rotated to drive the adjusting threaded rod 403 to rotate, thereby driving the two sets of articulated blocks 501 to move away from or approach each other, and then adjusting the minimum spacing after the clamping end of the clamping arm 6 is clamped, that is, the larger the spacing between the two sets of articulated blocks 501, the smaller the minimum spacing after the clamping end of the clamping arm 6 is clamped, and the smaller the thickness of the foam plastic board that can be clamped is, and the most suitable spacing between the articulated blocks 501 is obtained through debugging and applied to other clamping devices, saving the time of re-debugging and improving the debugging efficiency. During the debugging process, the debugger will constantly adjust the spacing between the two sets of hinge blocks 501 and conduct a clamping experiment. During clamping, the foam plastic will cause the clamping arm 6 to be subjected to a reverse force. The clamping arm 6 squeezes the roller 708, and the roller 708 drives the sliding sleeve 705 to move. The sliding sleeve 705 squeezes the measuring spring 704, and the measuring spring 704 contracts to cause the relative position of the sliding sleeve 705 and the detection plate 703 to move. By observing the pressure range corresponding to the position of the detection plate 703, the force applied to the measuring spring 704 can be determined. The pressure range is divided into three parts, corresponding to the three clamping strengths of weak, medium and strong. The detection plate 703 is painted with bright colors for easy observation during the debugging process. At the same time, the measuring spring 704 can also be used as a pressure buffer component to reduce damage to the foam plastic during the clamping process.

[0030] In the process of the transmission threaded rod 2 driving the threaded block 701 to move forward and backward, the clamping arm 6 between the ball 707 and the roller 708 will tilt to a certain extent. The tilted state will squeeze the ball 707 and the roller 708, so that the ball 707 moves downward, thereby adapting to the state change of the clamping arm 6 to ensure the smooth progress of the clamping operation. It should be noted that the pressing spring 706 and the measuring spring 704 are implemented on different objects. When the pressure detection mechanism 7 moves along the transmission threaded rod 2, the compression degree of the pressing spring 706 will change with the change of the tilt angle of the clamping arm 6, while the measuring spring 704 will not be compressed. When the clamping plate 9 clamps the foam plastic, the clamping arm 6 will lift the sliding sleeve 705, so that the measuring spring 704 between the sliding sleeve 705 and the detection plate 703 is compressed, and at this time, the compression degree of the pressing spring 706 still depends on the tilt angle of the clamping arm 6. The outer frame 8 is responsible for protecting the internal components and reducing the influence of external dust, waste, foam plastic blocks and other objects on the internal components of the outer frame 8. The two groups of clamping arms 6 are clamped by the clamping plate 9, and the flexible cushion is responsible for increasing the friction coefficient with the foam plastic to ensure stability during clamping or transportation.

[0031] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
