Description
TECHNICAL FIELD
[0001] The utility model relates to a measuring article, especially a portable ruler for measuring the width of rubber. BACKGROUND
[0002] In the process of soft capsule pill pressing, manufacturers often only pay attention to the thickness of rubber, but ignore the width of rubber, and the width of rubber reflects the stretching degree of rubber during pill pressing. When the rubber is excessively stretched, especially the rubber near the nozzle, it will cause the freshly pressed rubber pill to shrink sharply, affecting the joint, so the width of rubber needs to be measured during pill pressing to ensure that the width of rubber is within a suitable range. The width of rubber near the nozzle can be measured directly by an ordinary ruler, but the width of rubber near the nozzle can best reflect the stretching degree of rubber during pill pressing. For the rubber near the nozzle, due to the small space, combined with the movement of the rubber, it is difficult to detect by a ruler, and there is a risk of damaging the pill pressing mold by the ruler. SUMMARY
[0003] The utility model solves the technical problem of providing a portable ruler for measuring the width of rubber, which can measure the width of rubber without being close to the nozzle, is more accurate, has no risk of damaging the pill pressing mold, is convenient to carry, and is easy to operate.
[0004] To solve the above technical problems, the technical scheme adopted is as follows:
[0005] A portable ruler for measuring the width of rubber, comprising a scale ruler, characterized in that: it further comprises a fixed laser emitter and a movable laser emitter, the laser emission directions of the fixed laser emitter and the movable laser emitter are both perpendicular to the scale ruler, the fixed laser emitter is fixedly arranged on the scale ruler, and the fixed laser emitter is aligned with the zero scale line of the scale ruler, the movable laser emitter is installed on the scale ruler and can move along the length direction of the scale ruler; the upper part of the scale ruler is provided with a handle.
[0006] The portable ruler is used in the process of pressing the soft capsule, and a staff member can hold the handle to suspend the scale above the rubber, and then open the fixed laser emitter and the movable laser emitter. The laser emitted by the fixed laser emitter is first aligned with one side edge of the rubber, and then the position of the movable laser emitter is adjusted until the laser emitted by the movable laser emitter is aligned with the other side edge of the rubber. At this time, the distance between the lasers emitted by the fixed laser emitter and the movable laser emitter is the width of the rubber, and the width can be directly read from the scale. When the width of the rubber is measured, the portable ruler can be used without approaching the spray body, and the risk of damaging the pressing die is avoided. The laser irradiation method can also ensure that the scale is parallel to the rubber (when the scale is not parallel to the rubber, the irradiated laser is inclined, which can be easily found), so that the width of the rubber can be accurately measured without direct contact.
[0007] In the preferred embodiment, the portable ruler further comprises a moving piece, which is installed on the scale and can move along the length direction of the scale, and the movable laser emitter is fixedly installed at the lower end of the moving piece. When in use, the position of the movable laser emitter is adjusted by moving the moving piece on the scale.
[0008] In the further preferred embodiment, the moving piece is a sleeve, the inner hole of the sleeve is matched with the scale in shape and size, and the sleeve is sleeved on the scale. When the position of the movable laser emitter is adjusted, the sleeve is directly dragged to move on the scale, so that the laser of the movable laser emitter is not blocked.
[0009] In the still further preferred embodiment, the side wall of the sleeve is transparent, the front side wall of the sleeve is provided with a mark extending in the up-down direction, the mark corresponds to the scale position of the scale, and the extension direction of the mark is the same as the laser emission direction of the movable laser emitter. With this structure, the mark and the laser emission direction of the movable laser emitter are on the same straight line, so that when the position of the movable laser emitter is adjusted, the mark on the sleeve points to the position of the corresponding scale on the scale, which is the width of the rubber, and the staff member can directly read the number.
[0010] In the still further preferred embodiment, the portable ruler further comprises a locking bolt, the rear side wall of the sleeve is provided with a screw hole, the locking bolt is threadedly connected with the screw hole, and the rod end of the locking bolt is in contact with the side wall of the scale. When the position of the movable laser emitter needs to be adjusted, the locking bolt is loosened, so that the sleeve can move on the scale. After adjustment, the locking bolt is tightened to fix the position of the sleeve and the movable laser emitter, which is suitable for continuous measurement and rapid checking of the over-stretched rubber.
[0011] In the preferred solution, the handle is arched, and the two ends of the handle are hingedly connected to the two ends of the scale.
[0012] In the preferred solution, the scale has a range of 0-350 mm, and the scale is accurate to the millimeter. According to actual needs, scales with different ranges and different scale accuracies can also be used.

[0017] The present application will be further described below in combination with the drawings and specific embodiments:
[0018] As shown in the drawings, a portable ruler for measuring rubber width comprises a scale 1, a fixed laser emitter 2 and a movable laser emitter 3. Figures 1-3 The laser emission directions of the fixed laser emitter 2 and the movable laser emitter 3 are both perpendicular to the scale 1. The fixed laser emitter 2 is fixedly arranged on the scale 1, and the fixed laser emitter 2 is aligned with the zero scale line of the scale 1. The movable laser emitter 3 is installed on the scale 1 and can move along the length direction of the scale 1. An upper portion of the scale 1 is provided with a handle 4.
[0019] The portable ruler is used in the process of pressing the soft capsule, and the staff can suspend the scale ruler 1 above the rubber by holding the handle 4, and then open the fixed laser emitter 2 and the movable laser emitter 3. First, the laser emitted by the fixed laser emitter 2 is aligned with one side edge of the rubber, and then the position of the movable laser emitter 3 is adjusted until the laser emitted by the movable laser emitter 3 is aligned with the other side edge of the rubber. At this time, the distance between the lasers emitted by the fixed laser emitter 2 and the movable laser emitter 3 is the width of the rubber, and can be directly read by the scale ruler 1. When measuring the width of the rubber, the portable ruler can be used without approaching the spray body, and the risk of damaging the pressing die is avoided. The laser irradiation method can also ensure that the scale ruler 1 is parallel to the rubber (when the scale ruler 1 is not parallel to the rubber, the irradiated laser will be inclined, which can be easily found), so that the width of the rubber can be accurately measured without direct contact.
[0020] The portable ruler also includes a moving piece 5, which is installed on the scale ruler 1 and can move along the length direction of the scale ruler 1. The movable laser emitter 3 is fixedly installed at the lower end of the moving piece 5. When used, the position of the movable laser emitter 3 is adjusted by moving the moving piece 5 on the scale ruler 1.
[0021] The moving piece 5 is a sleeve, and the inner hole shape and size of the sleeve match the scale ruler 1. The sleeve is sleeved on the scale ruler 1. When adjusting the position of the movable laser emitter 3, the sleeve is directly dragged to move on the scale ruler 1, which will not block the laser of the movable laser emitter 3.
[0022] The side wall of the sleeve is transparent, and the front side wall of the sleeve is provided with a mark 501 extending in the upward and downward direction. The mark 501 corresponds to the scale position of the scale ruler 1, and the extension direction of the mark 501 is the same as the laser emission direction of the movable laser emitter 3. With this structure, the mark 501 and the laser emission direction of the movable laser emitter 3 are on the same straight line, so when the position of the movable laser emitter 3 is adjusted, the mark 501 on the sleeve points to the position of the corresponding scale on the scale ruler 1, which is the width of the rubber, and the staff can directly read the number.
[0023] The portable ruler also includes a locking bolt 6, and a screw hole is opened in the rear side wall of the sleeve. The locking bolt 6 is threadedly connected with the screw hole, and the rod end of the locking bolt 6 is in contact with the side wall of the scale ruler 1. When the position of the movable laser emitter 3 needs to be adjusted, the locking bolt 6 can be loosened, so that the sleeve can move on the scale ruler 1. After adjustment, the locking bolt 6 can be tightened to fix the position of the sleeve and the movable laser emitter 3, which is suitable for continuous measurement and rapid checking of over-stretched rubber.
[0024] The handle 4 is arched, and the two ends of the handle 4 are hingedly connected with the two ends of the scale ruler 1.
[0025] The scale 1 has a range of 0-350 mm and is graduated to the nearest mm. Depending on the actual requirements, scales 1 having a different range and graduation accuracy can also be used.
