The utility model discloses a cold press capable of pressing special-shaped aluminum profiles, which relates to the field of cold press devices and comprises an operation table, a hydraulic mechanism is arranged above the operation table and comprises a top plate, a hydraulic lifting column and a pressing plate, and supporting structures are arranged on two sides of the operation table. The supporting structure comprises a supporting base, a supporting column and a groove, a first switch is installed at the position, close to the upper portion, in the groove, a second switch is installed at the position, close to the lower portion, in the groove, and reset grooves are formed in the positions, close to the front and rear portions, of the surfaces of the two sides of the pressing plate. The first switch, the second switch and the reset groove are arranged in the hydraulic cylinder, so that the oil pressure sealing load of the hydraulic cylinder can be reduced, the service life of the hydraulic cylinder is effectively prolonged, meanwhile, after pressing is completed, demolding operation is facilitated, and the production efficiency is improved.

The utility model discloses a thickness measuring device for bipolar plate production, which comprises a measuring column, a sliding block and a measuring plate, the sliding block is slidably connected to the surface of the measuring column, the measuring plate is fixedly connected to the front side of the surface of the sliding block, the bottom of the measuring column is fixedly connected with a measuring mechanism, and the measuring mechanism comprises a reference platform. And the reference platform is fixedly mounted at the bottom of the measuring column. According to the utility model, the distance measuring sensor is used for automatically detecting the distance and transmitting data to the control panel, so that the intelligentization of the thickness measurement of the bipolar plate is realized, the workload of operators is greatly reduced, and when a large number of bipolar plate measurement tasks are performed, the measurement efficiency can be obviously improved, and the time and energy are saved; and meanwhile, the arrangement of the reference platform can ensure the flatness of the bipolar plate when the bipolar plate is placed, so that the problem that in the practical application process of the patent equipment, an operator needs to manually rotate the rotating block so as to push the threaded rod to fix the measuring block, and the operation process is relatively complicated is solved.

This invention relates to the field of medical device technology and discloses a surgical pack waste collection device, comprising a housing, within which three waste dispensing boxes are fixedly installed, arranged side-by-side in a front-to-back direction. A first waste chute and two second waste chutees are also fixedly installed on the housing. The inner cavity of the first waste chute communicates with both second waste chutees, and the first waste chute communicates with the middle waste dispensing box. The two second waste chutes communicate with the other two waste dispensing boxes respectively. Two valve mechanisms and a stiffness detection mechanism are provided within the first waste chute. This surgical pack waste collection device, within the waste collection box, utilizes the gradient stiffness detection mechanism to trigger different sliding rods based on the stiffness differences of the waste itself, thereby controlling the valve mechanisms located at the connections of different chutees, achieving automatic waste sorting and collection.

The probe for the computerized flat knitting machine is an elastic probe, and the elastic structure with the automatic reset function and the buffering function is integrally arranged on the probe. The utility model also relates to a broken needle alarm device, which comprises two probes arranged on the left and right of the machine head through insulating bases, an alarm control assembly, the probe is an elastic probe, the elastic structure with the automatic reset function and the buffering function is integrally arranged on the probe, the upper portion of the probe is connected with a weak current lead, and the machine head moves left and right on the needle plate to realize knitting. When the probe lower portion and the broken needle needle foot falling from the needle plate contact, the circuit of the alarm control assembly is connected to realize the broken needle alarm. The elastic probe can effectively reduce the impact force of the needle foot contact and automatically reset after the broken needle alarm is removed. In addition, the probe is arranged at the inner bottom plate of the machine head of the computerized flat knitting machine and located between the left and right sides of the needle lifting cam and the needle returning cam, so that the detection of the broken needle is more timely and accurate, and the knitting product quality is improved.
