Description

Needling mechanism sliding guide upright column displacement driving device of felt sleeve conical needling machine

Technical Field

The utility model belongs to the technical field of non-woven felt sleeve needling equipment, and particularly relates to a needling mechanism sliding guide upright column displacement driving device of a felt sleeve conical needling machine.

Background

The felt cover blank mentioned above essentially refers to a protective sleeve-shaped blank which is obtained by the previous process, needs to be subjected to secondary needling to achieve densification (also called as "stiffening") and has a round table shape or a shape as seen in daily life. The previous process is as follows: the method comprises the steps of needling a non-woven felt made of carbon fibers by a needling machine, cutting the non-woven felt into a trapezoidal felt piece according to a required size, and sewing two sides of the trapezoidal felt piece in the length direction by an industrial sewing machine or similar equipment to form a round table-shaped green body with a small diameter at one end and a large diameter at the other end, so as to form a felt sleeve embryonic form. Since common needling machines such as CN101149286B (automatic multifunctional needling machine), CN102808290B (roller needling machine), CN106087258B (double-sided butt needling machine), CN105734836a (a low-noise needling machine), CN106087259a (a high-speed biaxial-guiding ectopic butt needling machine) and CN106988023a (a small blanket-covering needling machine), CN211036324U (a needling machine for processing carbon fiber products), CN211171122U (flat-plate carbon fiber needling machine), CN212771285U (a needling machine for carbon fiber products), CN103161033B (a needling machine for processing carbon fiber products) and the like cannot perform secondary needling on the round-table-shaped blanket-covering embryonic form, at least the following technical elements are required in terms of structure: the device comprises a frame, a felt cover die rotary driving mechanism arranged at the lower part of the frame and used for driving the felt cover die to rotate, a felt cover die arranged on the felt cover die rotary driving mechanism and driven to rotate by the felt cover die rotary driving mechanism, a felt cover embryonic needling mechanism, a needling frame up-and-down displacement driving mechanism capable of enabling the felt cover embryonic needling mechanism to move up and down, a needling mechanism sliding guide upright post used for guiding the felt cover embryonic needling mechanism in a sliding manner, a needling mechanism sliding guide upright post driving device used for enabling the needling mechanism sliding guide upright post to move left and right, and the like.

From the above description, it is basically known that: the secondary needling of the felt cover embryonic form sleeved on the felt cover die is performed by a felt cover embryonic form needling mechanism from top to bottom, and as the diameter of the felt cover die gradually increases from top to bottom, the felt cover embryonic form needling mechanism needs to be slowly moved from top to bottom in the needling process, meanwhile, the sliding guide upright post of the needling mechanism and the felt cover embryonic form needling mechanism need to be gradually moved (translated) towards the direction away from the felt cover die, and after the needling of the felt cover embryonic form sleeved on the felt cover die is completed, a finished product is obtained, namely the felt cover for heat preservation, heat insulation and impact resistance packaging of industrial products and military products which need special protection is taken off from the felt cover die, and meanwhile, the felt cover embryonic form needling mechanism returns upwards and the felt cover embryonic form needling mechanism slides and guides the upright post to move towards the direction of the cover die so as to needle the next felt cover embryonic form.

The driving device of the sliding guide upright of the needling mechanism for driving the needling mechanism to move together with the felted embryonic needling mechanism is a very important device in the structural system of the felted embryonic needling machine, because the simplicity of the structure of the driving device is considered, the moving stability of the sliding guide upright of the needling mechanism is ensured, and the driving device needs to pay attention to the factors such as no interference with a frame and other mechanisms. However, since there is no reference to how to optimize the above-mentioned factors, neither in the patent nor non-patent documents disclosed so far, the technical solutions to be described below are produced in this context.

With continued reference to fig. 1, since the structure and arrangement of the right needling frame up-down displacement driving mechanism 40 is the same as that of the left needling frame up-down displacement driving mechanism 30, the applicant only describes the left needling frame up-down displacement driving mechanism 30 below, the left needling frame up-down displacement driving mechanism 30 includes a left needling frame up-down displacement driving motor 301, a left needling frame up-down displacement driving reduction gearbox 302 and a left needling frame up-down displacement driving screw 303, the left needling frame up-down displacement driving motor 301 is a motor with a forward and backward rotation function, the left needling frame up-down displacement driving motor 301 is in transmission connection with the left needling frame up-down displacement driving reduction gearbox 302 and is fixed with the left needling frame up-down displacement driving reduction gearbox fixing seat 3021 by the left needling frame up-down displacement driving reduction gearbox 302 together with the left needling frame up-down displacement driving motor 301, the left needling frame up-down displacement driving reduction gearbox fixing seat 3021 is fixed with the left side of the upper end of the left upright post 10, the left needling frame up-down displacement driving reduction gearbox final stage power output shaft of the left needling frame up-down displacement driving reduction gearbox 302 is in transmission connection with a screw head of the upper end of the left needling frame up-down displacement driving screw 303 through a left needling frame up-down displacement driving reduction gearbox final stage power output shaft coupling 3022, the upper end of the left needling frame up-down displacement driving screw 303 is in threaded fit with a driving screw upper supporting seat 3031, the driving screw upper supporting seat 3031 is fixed with the left side of the left upright post 10, the lower end of the left needling frame up-down displacement driving screw 303 is rotatably supported on a driving screw lower supporting seat 3032, and the driving screw lower supporting seat 3032 is fixed with the left side of the lower end of the left upright post 10; the left needling rotating seat angle adjusting mechanism 5 is matched with the left needling mechanism 7 in a transmission way with the left needling frame up-down displacement driving screw 303; the structure of the right needling rotary seat angle adjusting mechanism 6 is the same as that of the left needling rotary seat angle adjusting mechanism 5; the structure of the right needling mechanism 8 is the same as that of the left needling mechanism 7.

When the left needling frame up-down displacement driving motor 301 with the forward-backward rotation function works, the left needling frame up-down displacement driving reduction gearbox 302 is driven by the left needling frame up-down displacement driving reduction gearbox 302, the left needling frame up-down displacement driving reduction gearbox final power output shaft drives the left needling frame up-down displacement driving screw 303 to rotate through the left needling frame up-down displacement driving reduction gearbox final power output shaft coupling 3022, so that the left needling frame angle adjusting mechanism 5 is driven by the left needling frame up-down displacement driving screw 303 to correspondingly displace upwards or downwards along with the left needling mechanism 7, the upward or downwards displacement depends on the rotation direction of the left needling frame up-down displacement driving screw 303, such as clockwise or anticlockwise rotation direction, the rotation direction of the left needling frame up-down displacement driving screw 303 depends on the working state of the forward rotation or reverse rotation of the left needling frame up-down displacement driving motor 301, and the limit of the upward displacement of the left needling frame angle adjusting mechanism 5 is controlled by the left needling frame up-down limit signal collectors 102 and 103 respectively, namely, the left needling frame up-down limit signal collectors 102 and the electric control device control the upper needle frame 301.

Also shown in fig. 1 is a mat sheath blank 50 to be needled for a second time and placed over mat sheath former 9. In this embodiment, the applicant adopts travel switches for the left column fixing base left limit position signal collector 261, the left column fixing base right limit position signal collector 262, the right column fixing base right limit position signal collector 361, the right column fixing base left limit position signal collector 362, the left needling frame upper and lower limit signal collectors 102, 103, and the right needling frame upper and lower limit signal collectors 202, 203, but may also adopt micro switches, position proximity switches, reed switches, or hall sensing elements.

With continued reference to fig. 1, when the aforementioned left-column lateral displacement driving motor 21 controlled by the electric controller is operated, the left-column lateral displacement driving reduction gearbox 22 is driven by the left-column lateral displacement driving motor, and since the left-column lateral displacement driving screw coupling 241 is used for driving the left-column lateral displacement driving reduction gearbox final power output shaft of the left-column lateral displacement driving reduction gearbox 22 to be in driving connection with the left end (screw head at the left end) of the left-column lateral displacement driving screw 24, the left-column lateral displacement driving screw 24 is driven by the left-column lateral displacement driving screw coupling 241 to rotate, the left-column lateral displacement driving screw nut block 25 is driven by the left-column lateral displacement driving screw nut block 25 to drive the left-column fixing seat 26 to displace, and in the process, the pair of left-column fixing plate guiding sliding seats 27 slide along the pair of left-column fixing plate guiding sliding seat guide rails 28. Because the lower end of the left upright post 10 is fixed with the side of the left upright post fixing seat 26 facing upwards, and because the upper end, namely the top of the left upright post 10 is in sliding fit with a pair of left upright post upper end sliding guide rails 1613 of the structural system of the left upright post upper end sliding guide device 161 through the pair of left upright post top guiding sliding blocks 105, the left upright post fixing seat 26 is driven to correspondingly displace while being displaced. The rightward or leftward displacement of the left column holder 16 depends on the clockwise or counterclockwise rotation of the left column lateral displacement drive screw 24, and the clockwise or counterclockwise rotation of the left column lateral displacement drive screw 24 depends on the forward or reverse operation state of the motor shaft of the left column lateral displacement drive motor 21.

In the process of the left upright post 10 moving leftwards or rightwards, the left needling frame up-and-down displacement driving mechanism 30, the left needling rotating seat angle adjusting mechanism 5 and the left needling mechanism 7 which are arranged by taking the left upright post as a carrier are driven by the left upright post to correspondingly displace.

Since the working process of the right column lateral displacement driving mechanism 3 is the same as that of the left column lateral displacement driving mechanism 2, the principle of the first to third aspect can be fully understood. Accordingly, the applicant does not repeat the description.

In the process of needling the felt cover blank 50, the felt cover die 9 (the felt cover die 9 is inserted and fixed on the rotating shaft of the felt cover die rotating driving mechanism 4) is driven by the felt cover die rotating driving mechanism 4 to rotate, so that the felt cover blank 50 sleeved outside is driven by the felt cover die 9 to correspondingly rotate. Since needling of the mat rudiment 50 is usually performed from top to bottom, in the process of rotating the mat rudiment 50, under the operation of the left needling frame up-down displacement driving mechanism 30, the left needling rotating seat angle adjusting mechanism 5 and the left needling mechanism 7 in the needling state of the mat rudiment 50 are slowly moved downwards by the rotation of the left needling frame up-down displacement driving screw 303, and at this time, the left upright post 10 moves in a direction away from the mat rudiment 50 under the operation of the left upright post transverse displacement driving mechanism 2 until the left upright post fixing seat left-going limit position signal collector 261 touches the right side of the frame left longitudinal upright post 14 and the lower part of the left needling rotating seat angle adjusting mechanism 5 touches the left needling frame lower limit signal collector 103, thereby indicating that needling of the mat rudiment 50 is completed. Then, the aforementioned left needling frame up-down displacement drive screw 303 rotates reversely and the left column lateral displacement drive screw 24 of the left column lateral displacement drive mechanism 2 rotates reversely, so that the left needling rotary seat angle adjusting mechanism 5 together with the left needling mechanism 7 displaces upward and the left column 10 displaces rightward, i.e., returns to the original state. The operation modes of the right needle frame up-down displacement drive mechanism 40 and the right column lateral displacement drive mechanism 3 are synchronized with the operation of the left needle frame up-down displacement drive mechanism 30 and the left column lateral displacement drive mechanism 2, respectively, and thus the description of the operation modes will not be repeated.
