The purpose of this arrangement is: through the preset operation of the automatic cutting machine, quantitative length rubber floor cloth with specified requirements is selected, then the cutter 251 and the tensioning roller 21 are ensured to move synchronously, then when the length of the rubber floor cloth entering the lower part of the driving roller 121 reaches the specified length, the pressing of the driving roller 121 and the driven roller 122 is completed, so that the driving roller 121 does not rotate, namely the rubber floor cloth is not conveyed downwards, the requirement of the total length required by cutting the rubber floor cloth is ensured, multiple cutting of the specified length requirement of the rubber floor cloth is realized under the cooperation of a plurality of groups of sliding tensioning groups 24 structures below, single automatic cutting operation is realized, and the manufacturing of a plurality of rubber floor cloth single products with specified lengths can be completed, thereby greatly improving the automation degree of the device and simultaneously improving the cutting operation efficiency of the rubber floor cloth.

Further preferred embodiments are shown in fig. 9: the adjusting mechanism 4 includes an adjusting column 41, an adjusting lever 42, and an adjusting block 43. The adjusting columns 41 are vertically distributed, extend downwards to the jacking groove 85 through the jacking plate 83, and can rotate relative to the jacking plate 83. The adjusting rod 42 is coaxially arranged below the adjusting column 41, and the outer side wall is provided with threads. The adjusting block 43 is arranged at the lower end of the adjusting rod 42, is internally provided with a groove, and keeps relative rotation with the adjusting rod 42, thereby realizing the telescopic change of the whole length of the adjusting mechanism 4. The adjusting block 43 is of a square structure and is installed in a matched manner with the square groove 56; a spring 44 is also provided in the pressing groove 85 and below the moving lever 55. One end of the spring 44 is connected with the bottom wall of the pressing groove 85, and the other end is connected with the bottom wall of the moving rod.

The purpose of this arrangement is: the height between the ram block 82 and the center of the drive roll 121 determines the length of transport of the rubber floor cloth into the "cutter structure". Specifically, as long as the driving roller rotates, the feeding of the rubber floor cloth can be driven, which means that when the length requirement of the rubber floor cloth entering the cutter structure area is met, the driving roller is controlled not to rotate any more. The smaller the height between the top press block 82 and the center of the drive roller 121, the smaller the overall conveying length into the "cutter structure", and the smaller the length of the rubber floor cloth spread out into each set of sliding tension set 24 structures; therefore, through the arrangement of the adjusting mechanism 4, the rotation of the driving mechanism 3 can be realized, and through the transmission cooperation of the transmission structure 5, the initial adjustment of the descending height of the jacking structure 8 is driven, so that the time and the labor are saved, and the problem that the length requirement of the rubber floor cloth sheet can be adjusted only by disassembling and replacing the assembly is avoided; greatly improves the high efficiency and the service life of the cutting machine.

The working process comprises the following steps:

firstly, a worker adjusts the adjusting mechanism 4 according to the length requirements of rubber floor cloth items with different specifications, particularly rotates the adjusting column 41, and the adjusting block 43 is not moved due to the limiting effect of the adjusting block 43 and the square groove 56, so that the adjusting rod 42 can move in the groove of the adjusting block 43 relatively. That is, the length of the adjusting rod 42 can be changed by driving the adjusting column 41 to rotate in the forward and reverse directions, so that the length change of the whole adjusting mechanism 4 is satisfied. Further, since the sliding block 54 and the rotating sleeve 534 are fixed at this time, the lower end of the moving rod 55 has the spring 44 and is supported by enough elastic force, the length adjustment of the adjusting rod 42 becomes long, and the top pressing block 82 and the top pressing plate 83 are driven to integrally rise, so that the distance between the top pressing block 82 and the driving roller 121 and the driven roller 122 is prolonged, and the feeding stroke and time of the rubber floor cloth are relatively long, namely, the automatic production operation of cutting the long single rubber floor cloth is realized.

Secondly, the worker starts a servo motor, and the servo motor rotates to drive the driving roller 121 to rotate, so that the rubber floor cloth flatly laid on the transmission table 111 is pulled to integrally move under the extrusion drive of the driving roller 121 and the driven roller 122 on the rubber floor cloth. In the initial state, the end portion of the rubber floor cloth is caused to pass through the driving roller 121 and the driven roller 122. Until the end of the rubber floor cloth passes through the crosswise distributed tensioning rollers 21 to the lowest tensioning roller 21 position. Then, the cylinder 62 is started, the cylinder 62 drives the cylinder arm 63 to stretch, the end part of the cylinder arm 63 can be arranged into an arc shape, and further under the cooperation of the tensioning roller 21, the fastening and positioning of the bottom end of the rubber floor cloth are formed, so that the subsequent tensioning and cutting are facilitated.

In this embodiment, the control modes of the operation of the servo motor, the driving motor 31 and the cylinder 62 may be manual operation, or may be automatic control by a PLC controller, i.e. the control circuit of the PLC controller is simply controlled to start and close, and may be implemented by simple programming by a person skilled in the art, which belongs to the common general knowledge in the art, and the present application is mainly used for protecting mechanical devices, so the present application does not explain the control modes and circuit connections in detail.

Next, the driving motor 31 is started, the driving motor 31 drives the transmission gear 33 to rotate synchronously with the first bevel gear 51, wherein the transmission gear 33 rotates clockwise and drives the two transverse connecting rods 221 which are in meshed transmission to move reversely, namely, the transverse connecting rods 221 of the left moving plate 22 move leftwards, the transverse connecting rods 221 of the right moving plate 22 move rightwards, and finally, the two vertical connecting rods 222 move away from each other. In this movement, the two connecting arms 23 that are adjacently distributed drive the correspondingly connected tensioning rollers 21 away from each other, so that a movement is formed in which the tensioning rollers 21 pull the rubber floor cloth, so that the rubber floor cloth that enters into the areas of the plurality of tensioning rollers 21 is pulled to form a tensioned "fold line structure", so that a preset first tensioning length of the rubber floor cloth is reached. In this process, the tension roller 21 moves synchronously with the cutter 251 and the locking blade 72, and the distance between the tension roller and the cutter is unchanged.

In synchronization with this, the first bevel gear 51 and the second bevel gear 52 are engaged to drive the transmission rod 53 to rotate clockwise in synchronization. The connection protrusion 533 near the transmission post 531 and the fixing base 76 are kept rotatable relatively and immovable relatively. The connection post 532 and the rotating sleeve 534 move synchronously, that is, the transmission post 531 rotates synchronously with the second bevel gear 52, so as to drive the rotating sleeve 534 to rotate, and further drive the sliding block 54 to move downwards along the rotating sleeve 534. The friction resistance between the top pressing plate 83 and the mounting groove 84 is small and can be ignored, the elastic force support of the spring 44 is large enough, and then the sliding block 54 moves downwards, so that the top pressing plate 83 and the top pressing block 82 are synchronously driven to move downwards integrally until the top pressing block 82 contacts the driving roller 121 and the driven roller 122 to form a top pressing locking structure, the driving roller 121 does not rotate any more, and the servo motor stops working.

Then, the driving motor 31 continues to rotate clockwise, and at this time, the driving motor 31 continues to rotate, and the transmission gear 33 and the racks on the two transverse links 221 continue to transmit. Thus, the two vertical links 222 continue to move in a side-to-side horizontal direction, increasing tension, a transition of the tensioning operation. Further improves the tension of the rubber floor cloth, and is convenient for subsequent efficient and automatic cutting operation.

Meanwhile, in the process of changing the tension of the rubber floor cloth, the sliding block 54 continues to move downwards along the threads of the rotating sleeve 534 under the action of the spring 44 in the jacking groove 85, and the sliding block 54 moves downwards to press the spring 44 until the sliding block 54 is not moving because the jacking block 82 forms a jacking and locking state with the driving roller 121. In this process, the tension roller 21 and the cutter 251 and the locking cutter 72 are synchronously moved, and the interval between the tension roller and the cutter is unchanged.

Further, the driving motor 31 continues to rotate clockwise, and the rotating sleeve 534 continues to rotate clockwise, so that the sliding block 54 is not moved down, and the rotating sleeve 534 tends to move up. Further, the rotating sleeve 534 moves upwards, so that the pressure spring 538 above the rotating sleeve 534 is compressed, the grooved wheel 537 drives the lock blade 73 to move upwards, and then drives the lock blade arm structure to move upwards, and finally the clamping plate 724 is formed to move to the positioning structure of the fixing groove 74, at this time, the lock blade 72 completes the fixing operation, and even if the driving motor 31 continues to rotate, the lock blade 72 and the cutter 251 do not move left and right any more.

At the same time, the rack on the transmission gear 33 and the two transverse links 221 still continue to be transmitted during the positioning and fixing process of the locking knife 72. Thus, the two vertical links 222 continue to move in the left-right horizontal direction. The length change is smaller, and the tension degree of the single-product floor cloth is continuously increased. When the lock blade 72 is fixed, the cutter 251 is also not moved, and the tension roller 21 continues to move a slight distance along with the connecting arm 23, that is, the distance between the cutter 251 and the tension roller 21. At this time, the preset second tensioning length of the rubber floor cloth is realized, and the rubber floor cloth between the two adjacent tensioning rollers 21 in this state meets the preset single-product length requirement. The tension roller 21 drives the rubber floor cloth to move toward the cutter 251 until the flat cutting is completed. Therefore, the inclined pre-tensioning operation of the rubber floor cloth is realized, the length limitation of quantitative input of the rubber floor cloth is also realized, the continuous tensioning of the rubber floor cloth with quantitative length and the automatic cutting of single product leveling and high efficiency required by the appointed length are further completed, and the automatic cutting degree and the intelligent degree of the equipment are greatly improved.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
