Description

Technical Field

[0001] The utility model relates to the technical field of carpet production equipment, and particularly relates to a counting device for measuring the length of a carpet. Background Art

[0002] The varieties of household foot pad carpets and automotive carpets include nylon flat cut pile carpets, high cut low loop tufted woven carpets, etc. Their production process involves using yarn to weave tufts on the bottom base fabric and then cutting the lines, and performing processes such as applying glue on the bottom surface or covering the bottom strip and fixing the plastic on the back. During the preparation process of the carpet, it is necessary to measure the length of the carpet in order to know the production quantity for winding and cutting. Currently, in the carpet production workshop, generally, a roller counter rolls on the carpet, and then the length of the carpet is obtained by multiplying the rolling circumference by the number of rolling circles. This measured length will be displayed on the digital display screen of the roller counter.

[0003] However, after long-term use of the above-mentioned roller counter, the rollers will show different degrees of wear, and it is easy to slip, resulting in inaccurate measurement results. In addition, the counting of the roller counter is only displayed on its digital display screen and cannot be connected to the control system of the carpet production equipment. It is necessary for workers to specifically observe the value on the roller counter, and it is impossible to stop production or mark in a timely manner according to the counting value in real time; moreover, the error range of the online roller counter is one rolling circumference, and the error range is relatively large, which cannot meet the purpose of accurately measuring the production length of the carpet online. Summary of the Invention

[0004] The purpose of the utility model is to solve the deficiencies of the prior art and provide a counting device for measuring the length of a carpet that can prevent slipping, has high measurement accuracy, and can meet the on-line production requirements of the carpet.

[0006] Preferably, each row of nails extends to both ends of the nail roller, and adjacent two rows of nails are arranged in a staggered manner.

[0007] Preferably, the number of rows of the nails is 18 rows.

[0008] Preferably, the nail spacing between adjacent two nails is 10 - 20 mm.

[0026] To deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the implementation cases and the drawings. The present utility model can be implemented in the following ways:

[0027] Refer to Figures 1-6 , a counting device for measuring the length of a carpet, including a nail roller 1 movably installed between a plurality of traction rollers 5 of a winding device 4. A plurality of rows of nails 2 are evenly distributed on the circumferential surface of the nail roller 1; one end of the nail roller 1 is provided with an encoder 3 for counting, and the encoder 3 is electrically connected to the control system 6 of the carpet production equipment. The control system 6 of this embodiment is controlled by a PLC program. The PLC control system 6 controls the encoder 3 to count, and the current production number and the total production number can be monitored in real time on the display screen of the production equipment.

[0028] Specifically, the nail roller 1 is a seamless pipe. The diameter of the nail roller 1 is 89 mm. The wall thickness of the nail roller 1 is 8 mm. Each row of nails 2 extends to both ends of the nail roller 1, and two adjacent rows of nails 2 are arranged in a staggered manner. The staggered arrangement can reduce the probability of slipping. The number of rows of nails 2 in this embodiment is 18 rows. The nail spacing between two adjacent nails 2 is 10 - 20 mm. The nail spacing between two adjacent nails 2 in this embodiment is 15 mm. The denser the number of rows of nails 2, the less the probability of slipping and the higher the accuracy. However, if it is too dense, the nails 2 on the surface of the nail roller 1 will form a supporting surface, resulting in the nails 2 being unable to insert into the carpet 7, and then the nail roller 1 cannot be driven to rotate during the traction process of the carpet 7, so that the length of the carpet 7 cannot be counted. The number of rows of nails 2 set in this embodiment is 18 rows, which is exactly between the balance of the above two, while improving the counting precision, enabling each row of nails 2 to be inserted into the carpet 7.

[0029] The nail 2 includes an embedding part 21 and a pointed cone 22 arranged at one end of the embedding part 21, and the pointed cone 22 protrudes from the roller surface. The circumferential surface of the nail roller 1 is provided with nail holes 11 for the nails 2 to be embedded. The nail 2 is made of stainless steel material to prevent rust from contaminating the carpet 7. When driving the nails, the embedding part 21 of the nail 2 is planted into the nail holes 11. The nail 2 in this embodiment protrudes 1.5 mm from the roller surface.

[0030] Both ends of the described nail roller 1 are provided with shaft heads 12, and a shaft hole 13 threadedly connected to the encoder 3 is provided at the outer end of one of the shaft heads 12. The shaft hole 13 is centered on the roller body. The working principle of the encoder 3 in this embodiment is mainly to convert the angular displacement into an electrical signal, and then convert this electrical signal into a counting pulse, and use the number of pulses to represent the magnitude of the displacement, and finally feedback it to the control system 6 of the carpet production equipment. When the count reaches the preset value, the entire carpet production equipment will stop production. At this time, production can be stopped according to the actual situation to complete winding or marking and continue production.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
