[0001] This utility model belongs to the field of cotton placemat production technology, and specifically relates to a cotton placemat punching machine. Background Technology

[0002] The main uses of cotton placemats include protecting the dining table, decorating the table, and enhancing the dining experience. Cotton placemats effectively protect tablecloths from oil stains and dirt, especially cotton tablecloths, avoiding the hassle of difficult cleaning. In addition, cotton placemats also have heat insulation and anti-scalding properties, effectively controlling the heat of tableware and protecting the table from damage by hot items.

[0003] Currently, a Chinese patent with publication number CN308939711S and publication date of November 15, 2024 discloses a placemat.

[0004] The placemat has through holes at the corners, which can be used for hanging. In the existing technology, when punching holes in the corners of cotton placemats, most of the time it is done manually with tools such as hole punchers. However, the efficiency of punching holes is relatively low, which is not conducive to the rapid punching of cotton placemats. Utility Model Content

[0005] The purpose of this invention is to provide a cotton placemat punching machine that can efficiently punch holes in cotton placemats.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cotton placemat punching machine, including a punching table, a column is provided on the upper side of the punching table, a driving cylinder is provided on the column, a connecting column is provided at the end of the piston rod of the driving cylinder, a punching tube is provided at the lower end of the connecting column, a through hole is provided on the punching table for the lower end of the punching tube to pass through, a connecting plate is fixed on the connecting column, guide sleeves are provided at both ends of the connecting plate, and guide posts with their upper ends passing through the guide sleeves are provided at both ends of the connecting plate, a pressure plate for pressing on the cotton placemat is provided between the lower ends of the two guide posts, an opening groove for the punching guide tube to pass through is provided at the center of the pressure plate, a connecting spring is sleeved on the guide post with one end connected to the pressure plate and the other end connected to the connecting plate, an L-shaped mounting groove is provided on the punching table, and an L-shaped positioning plate for positioning the corner of the cotton placemat slides up and down in the mounting groove.

[0007] A further feature of this invention is that: the upper end of the punch tube is provided with a mounting post with a rectangular cross-section; the lower end face of the connecting post is provided with a slot for the mounting post to be inserted and used in conjunction with the mounting post; the outer wall of the connecting post is provided with an internal threaded sleeve that communicates with the slot; and the internal threaded sleeve is internally threaded with a locking bolt whose end is used to abut against the mounting post.

[0008] A further feature of this invention is that: an elongated hole is provided on the punching tube, the extension direction of which is parallel to the extension direction of the punching tube; a crossbar is provided in the elongated hole; both ends of the crossbar are provided with connecting arms that are connected to the pressure plate; a connecting rod is provided on the lower side of the middle part of the crossbar; and a push plate is provided at the lower end of the connecting rod for pushing out the fabric embedded in the punching tube.

[0009] A further feature of this invention is that the elongated hole penetrates the mounting post.

[0010] A further feature of this invention is that a beveled section is formed on the inner wall of the lower end of the punch tube.

[0011] A further feature of this invention is that: a first connecting ear is provided on both sides of the positioning plate, a guide shaft is provided on the lower side of the first connecting ear, a second connecting ear is provided on both sides of the mounting groove and at the position corresponding to the first connecting ear, a guide hole is provided in the second connecting ear for the guide shaft to pass through, and a reset spring is sleeved on the guide shaft with one end connected to the first connecting ear and the other end connected to the second connecting ear.

[0012] A further feature of this invention is that both sides of the drilling platform are provided with start buttons that, when pressed simultaneously, control the start of the drive cylinder.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. When it is necessary to punch holes in cotton placemats, the positioning plate is used to position the corner of the cotton placemat. Then, the drive cylinder is activated. The piston rod of the drive cylinder drives the connecting column to move down until the pressure plate touches the positioning plate. This causes the positioning plate to move down and retract into the mounting groove. Then, the pressure plate can press against the cotton placemat on the punching table, and the connecting spring is compressed. As the connecting column continues to move down, the connecting column can drive the punching tube to press against the position where the hole needs to be punched at the corner of the cotton placemat. Then, the punching tube passes through the cotton placemat and enters the through hole. The drive cylinder can then return to its original position until the pressure plate leaves the cotton placemat. Compared with the existing technology that requires punching tools such as punch pliers to punch holes, it is much more labor-saving. At this time, efficient punching of cotton placemats can be achieved.

[0015] 2. When it is necessary to disassemble or assemble the punch tube, simply loosen the locking bolt, and then pull down the mounting post in the slot, which will facilitate the easy disassembly and assembly of the punch tube.

[0016] 3. When the drive cylinder returns to its original position and the connecting spring recovers its elasticity, the crossbar can move downward in the long hole. At this time, the crossbar can drive the push plate through the connecting rod. The push plate can then remove the fabric stuck in the punch tube, thereby avoiding the situation where the residual fabric after punching will block the punch tube.

[0017] 4. When it is necessary to disassemble or assemble the punch tube, use the elongated hole to pass through the mounting post. At this time, the crossbar can be moved up along the elongated hole and directly separated from the punch tube.

[0018] 5. The beveled part on the inner wall of the lower end of the punch tube makes the end of the punch tube sharper, which is conducive to smooth punching operation.

[0019] 6. The positioning plate uses the guide shaft of the first connecting ear to pass through the guide hole of the second connecting ear, and one end of the return spring is connected to the first connecting ear and the other end is connected to the second connecting ear. At this time, the positioning plate can slide up and down in the mounting groove, which is beneficial for the positioning plate to position the cotton placemat while avoiding interference with the pressure plate.

[0020] 7. When drilling is required, the operator needs to press the start button on both sides of the drilling table with both hands. This will prevent the operator's hands from being crushed by the falling drill tube, thereby improving the safety of the operation. Attached Figure Description
