According to the utility model, after the vertical buffer structure is arranged between the supporting frame and the supporting frame, when a needle head in a machine head of the pile cutting and looping equipment is aligned with a base cloth root at the edge to plant knitting wool, the condition that the vertical deformation quantity at the edge of the base cloth is relatively small can be made up through the vertical buffer structure; therefore, the situation that the edge of the base cloth is damaged due to the fact that the needle head excessively punctures the edge of the base cloth can be avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of cut pile and loop pile equipment, in particular to a base cloth supporting component of cut pile and loop pile equipment. Background Art

[0002] The cut pile loop pile equipment is a equipment used to root the pile yarn into the base cloth. In the process of rooting the pile yarn into the base cloth by the cut pile loop pile equipment currently available on the market, the outer edge of the base cloth is fixed on the support frame in the cut pile loop pile equipment. When the machine head in the cut pile loop pile equipment moves horizontally and the needle in the machine head moves back and forth vertically, the needle can root the pile yarn into the base cloth located on the support frame. However, in the cut pile loop pile equipment currently available on the market, the support frame in the cut pile loop pile equipment does not have a vertical buffer structure, and after the base cloth is clamped on the support frame, the edge of the base cloth is in a relatively tight state, and the middle part of the base cloth is in a relatively loose state, and when the needle in the machine head of the cut pile loop pile equipment moves vertically, the moving stroke of the needle is fixed. Therefore, when the needle roots the pile yarn into the base cloth located at the edge, due to the small vertical deformation amount at the edge of the base cloth, it is easy to cause the edge of the base cloth to be damaged due to excessive puncture by the needle. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a base cloth support assembly for a cut pile loop pile device, which, by arranging a vertical buffer structure between the support frame and the support frame, can compensate for the small vertical deformation amount at the edge of the base cloth by the vertical buffer structure when the needle in the machine head of the cut pile loop pile device is flocking the base cloth root located at the edge, thereby avoiding the damage to the edge of the base cloth caused by excessive puncture of the edge of the base cloth by the needle.

[0004] The utility model provides a base cloth supporting assembly of a cut pile loop pile equipment, comprising a frame, a supporting frame and a supporting frame; the supporting frame is connected to the frame, the supporting frame is located above the supporting frame and is used to support the base cloth, the outer edge of the base cloth is clamped on the supporting frame, a vertical buffer structure is arranged between the middle part of each side of the supporting frame and the supporting frame, and the supporting frame is connected to the supporting frame through the vertical buffer structure.

[0005] After the utility model sets a vertical buffer structure between the support frame and the support frame, when the needle in the machine head of the pile loop cutting device is flocking the pile thread at the base cloth root located at the edge, the vertical buffer structure can be used to compensate for the small vertical deformation amount at the edge of the base cloth, thereby avoiding the situation that the edge of the base cloth is damaged due to excessive puncture of the needle at the edge of the base cloth.

[0006] In a possible embodiment, each vertical buffer structure includes a support block and a spring; two guide posts are fixed at the lower end of each support block and are horizontally spaced apart; the lower end of each guide post is vertically movably arranged in the support frame; each spring is arranged between the support frame and the corresponding support block; each spring is used to apply a thrust to the support block at the corresponding position to drive the support block to move upward; an annular boss is arranged on the outer wall of the lower end of each guide post, and the annular boss is used to abut against the lower end surface of the support frame to prevent the guide post from detaching from the support frame from bottom to top; each side of the support frame is connected to the support block at the corresponding position; after the base cloth is clamped on the support frame, the edge of the base cloth is in a relatively tight state, the middle part of the base cloth is in a relatively loose state, and the needle in the head of the cutting pile loop equipment moves up and down, and the moving stroke of the needle is fixed. By adopting this buffer After the structure is constructed, when the needle in the machine head of the pile cutting and loop pile device pierces the edge of the base cloth from top to bottom, the edge of the base cloth is relatively tight. In order to avoid the damage to the edge of the base cloth caused by excessive piercing of the needle, when the needle pierces the edge of the base cloth, the support frame and the support block can compress the spring and move downward, thereby avoiding the situation where the needle excessively pierces the edge of the base cloth, that is, avoiding damage to the edge of the base cloth; when the needle in the machine head of the pile cutting and loop pile device is reset upward, the needle can be separated from the edge of the base cloth, and at this time, the spring can drive the support block, the support frame and the base cloth located on the support frame to move upward and reset; in addition, when the needle in the machine head of the pile cutting and loop pile device pierces the middle part of the base cloth from top to bottom, since the middle part of the base cloth is relatively loose, the support frame will not move downward relative to the support frame or the downward movement of the support frame relative to the support frame will be small.

[0007] In a possible implementation, the upper end of each spring is vertically inserted into the lower end of the support block at the corresponding position, and the lower end of each spring is abutted against the support frame; by adopting this structure, the spring can be limited to prevent the spring from detaching from the support block and the support frame.

[0008] In a possible implementation manner, the upper end of each guide column is threadedly connected to the support block; by adopting this structure, the upper end of each guide column can be reliably fixed to the support block.

[0009] In a possible implementation, the support block is made of magnetic material, and each side of the support frame is magnetically attracted to the support block at a corresponding position; by adopting this structure, the support frame can be easily connected to each support block, and the support frame can be easily removed from the support block.

[0010] In a possible embodiment, the support frame is connected to the frame so as to be movably forward and backward by two guide rail assemblies that are symmetrically arranged on the left and right; a linear drive mechanism is installed on the frame, and the support frame is fixed to the driving end of the linear drive mechanism, and the linear drive mechanism is used to drive the support frame to move forward and backward relative to the frame; after adopting this structure, the linear drive mechanism can drive the support frame to move forward and backward relative to the frame, so that the front and rear positions of the support frame and the base cloth can be easily adjusted. In addition, the linear drive mechanism is a linear drive mechanism composed of a servo motor, a screw rod and a nut sleeve, and the support frame is fixed to the nut sleeve in the linear drive mechanism. The linear drive mechanism is an existing drive device on the market, so it will not be described here. BRIEF DESCRIPTION OF THE DRAWINGS
