Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of expansion raw material belt detection, and specifically relates to a workbench for expansion raw material belt detection. BACKGROUND

[0002] The expansion raw material belt is prepared by coating a waterproof layer on non-woven fabric, and has multiple length specifications, so that the length of the expansion raw material belt needs to be sampled and detected before leaving the factory to check whether the length is within the allowable deviation range and whether the thickness meets the requirements. However, when the length and thickness of the expansion raw material belt are detected, the raw material belt is first laid along a measuring scale to measure the length, and then multiple measuring points are uniformly selected to measure the thickness with a thickness gauge. However, the expansion raw material belt has the following problems: 1) the raw material belt is usually manually unwound and rewound, which consumes a lot of time, and in particular, the rewinding process has the problem of uneven rewinding tightness; 2) when the raw material belt is laid along the measuring scale, the raw material belt is usually longer than the measuring scale, so that the raw material belt needs to be bent several times, and the bent part is easily displaced due to uneven force or accidental contact with the laid raw material belt, so that the laid raw material belt needs to be rearranged, which is laborious and seriously affects the detection efficiency. SUMMARY

[0003] The utility model aims at overcoming the defect that the bent part is easily displaced when the length of the raw material belt is measured in the prior art, and provides a workbench for expansion raw material belt detection.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] A workbench for expansion raw material belt detection, comprising a workbench table, two guide rods respectively arranged at two ends of the workbench table, a measuring scale arranged on the workbench table and located between the two guide rods, and a clamp arranged at one end of the workbench table; the start scale and the end scale of the measuring scale are respectively aligned with the corresponding guide rods.

[0006] As a further technical scheme, the clamping part of the clamp is arranged directly below the corresponding guide rod.

[0007] As a further technical scheme, at least two limiting plates are arranged on the guide rod away from the clamp, and at least two positioning scale lines are arranged on the guide rod close to the clamp.

[0008] As a further technical scheme, a foot pedal rewinding mechanism is further arranged on one side of the workbench table.

[0009] As a further technical solution, the foot-operated rewinding mechanism includes a motor, a raw material tape clamping mechanism disposed on the output shaft of the motor, a guiding mechanism disposed on one side of the raw material tape clamping mechanism, and a foot switch disposed under the workbench table, wherein the foot switch is electrically connected to the motor.

[0010] As a further technical solution, the foot-operated rewinding mechanism also includes a motor controller, which is electrically connected to the motor.

[0011] As a further technical solution, the snap-fit ​​mechanism includes a limiting baffle fixedly mounted on the rotating output shaft, and a snap-fit ​​component mounted on the limiting baffle, wherein the snap-fit ​​component is interference-fitted with the roll of the expanded raw material tape.

[0012] As a further technical solution, the snap-fit ​​component includes two snap-fit ​​plates symmetrically arranged on the limiting baffle.

[0013] As a further technical solution, the end of the snap-fit ​​plate away from the limiting baffle is bent inward.

[0014] As a further technical solution, the guiding mechanism includes a guiding rod and two guiding plates disposed on the guiding rod, with a raw material conveyor belt travel channel formed between the two guiding plates.

[0015] As a further technical solution, a thickness gauge is also included, and a shelf is provided on the workbench, on which the thickness gauge is placed.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model has a clamp at one end of the workbench and guide rods at both ends, and the guide rods are aligned with the end scale of the measuring ruler. In this way, when measuring the length, the PTFE tape can be wrapped around the two guide rods, thereby avoiding the displacement of the bending part due to uneven force or accidental contact, as in the traditional technology.

[0018] 2. This utility model is equipped with a foot-operated rewinding mechanism on the workbench. The hands and feet work together in conjunction with the motor to achieve semi-automatic rewinding of raw material tape. This not only improves the rewinding efficiency, but also solves the problem of uneven tension of each loop of raw material tape caused by manual rewinding. Attached Figure Description

[0029] As an embodiment of the workbench for testing expanded raw material strips according to this utility model, the vertical distance between the guide rod 2 and the measuring ruler 3 is less than or equal to 10cm; because during testing, if Figure 2 As shown, the starting end of the expanded raw material tape 20 is fixed to the workbench 1 by the clamp 4, and the guide rod 2 is located a distance above the table surface. Therefore, when the tape is first wound, it is tilted upward, which causes the actual length of the raw material tape to be greater than the measured length. In order to reduce this error and keep it within the standard deviation range, this utility model sets the vertical distance between the guide rod 2 and the measuring ruler 3 to be less than or equal to 10cm.
