Description

Technical Field

[0001] The utility model relates to a trimming device for yoga mats, and more specifically, to a stamping and cutting device for yoga mats. Background Art

[0002] The processing of yoga mats includes the following processes:

[0003] 1. Preparation of slurry: Select corresponding raw materials according to the formula and mix and stir them into a latex-like mixture;

[0004] 2. Machine debugging and slurry brushing: Include the boiler worker heating up and preheating, setting and debugging parameters in each area, and putting the relevant slurry and mesh fabric onto the machine in place;

[0005] 3. Slurry brushing: Pull the mesh fabric to the needle rail, tension and flatten it, and then brush the slurry for production;

[0006] 4. High-temperature foaming: Pull the mesh fabric with the slurry brushed on it to the temperature chamber through the needle plate for high-temperature foaming and forming;

[0007] 5. Cooling and shaping: After the product is foamed and formed, lead it out of the temperature chamber to gradually dissipate heat and then cool and shape it;

[0008] 6. Trimming and cutting: Adjust the distance of the tail knife rest to cut the material according to the order requirements.

[0009] In the sixth step of the process, the factory needs to place the yoga mat on the stamping equipment for stamping and cutting to remove the burrs. For the existing cutting equipment, the worker needs to place the yoga mat on the sliding lower template, then push the lower template under the upper template, and then start the upper template to press down. The upper template is provided with a cutting knife, and after stamping, the edge of the yoga mat is cut.

[0010] However, such a cutting device has a defect that every time the worker places the yoga mat on the lower template, they need to judge whether the front position of the placement is accurate, and there are often situations where the cutting position is not aligned, resulting in the scrapping of the yoga mat. Summary of the Utility Model

[0011] The purpose of the utility model is to provide a stamping and cutting device for yoga mats, which can more accurately position the placement position of the yoga mat on the lower template, improve the cutting accuracy of the yoga mat, and reduce the cutting scrap rate of the yoga mat.

[0012] The above technical purpose of the utility model is achieved through the following technical solutions:

[0013] A stamping and cutting device for yoga mats includes a machine base. The machine base is provided with an upper template and a lower template. The upper template is provided with a cutting knife. The machine base is provided with two transverse slide rails. The lower template slides on the slide rails. The machine base is provided with a power component for pushing the lower template in and out directly below the upper template;

[0014] The lower template is provided with a first positioning block for front-end positioning, and the first positioning block protrudes on the upper surface of the lower template; the lower template is provided with a mounting block, and the first positioning block slides vertically on the mounting block, and the mounting block is provided with a first spring to lift the first positioning block; the first positioning block is a prism structure, and the first positioning block is located on the outside of the cutter.

[0015] Preferably, the power assembly is a screw assembly.

[0016] Preferably, there are two first positioning blocks.

[0017] Preferably, the lower template is provided with a slide groove, a guide rod is provided in the slide groove, the mounting block slides on the guide rod, the guide rod sleeve is provided with a compression spring, one end of the compression spring abuts against the end of the slide groove, and the other end of the compression spring abuts against the mounting block; the guide rod is threadedly connected to a nut for positioning the mounting block; the nut and the compression spring clamp the mounting block.

[0018] Preferably, the screw assembly is provided with a driving motor, and the edge of the lower template is provided with an anti-collision touch strip that turns off the motor when compressed. The anti-collision touch strip is located at the side edge of the lower template and is located between the two slide rails.

[0019] Preferably, a flexible strip is provided on the outer surface of the anti-collision contact strip.

[0020] Preferably, a left positioning block is provided on the left side of the lower template, and a right positioning block is provided on the right side of the lower template. The left positioning block and the right positioning block have the same structure as the first positioning block.

[0021] Preferably, the left positioning block and the right positioning block are symmetrically arranged on both sides of the first positioning block.

[0022] In summary, the present invention has at least one of the following beneficial effects:

[0023] (1) Description of pyramid: A pyramid is cut with a plane parallel to its base. The part between the base and the cross section is called a pyramid.

[0024] This design uses a first positioning block that can be extended up and down to provide a barrier and positioning for the front end of the yoga mat, so that the front end of the yoga mat can be accurately positioned when placed in the lower mold, avoiding the occurrence of cutting and scrapping of the yoga mat due to inaccurate positioning of the front end by the staff. Cutting and scrapping may be due to inaccurate positioning, resulting in excessive or insufficient cutting of the edge of the yoga mat, resulting in an irregular overall shape of the yoga mat.

[0025] The first positioning block must be retractable because the first positioning block will also be squeezed during the pressing process of the upper and lower templates. The first positioning block must have a retractable performance to provide sufficient vertical space to allow the upper and lower templates to be closed smoothly.

[0026] Secondly, the purpose of the prism structure design of the first positioning block is that during the downward movement of the first positioning block, due to the inclined structure of the prism, the gap between the first positioning block and the yoga mat becomes larger and larger, so that the first positioning block will not push the yoga mat due to the friction generated by the relative vertical movement, ensuring that the yoga mat can be cut smoothly and smoothly. If the positioning surface of the positioning block is vertically flat, then the positioning surface will rub against the yoga mat during the downward movement, pushing the yoga mat to twist slightly, resulting in a small amount of undulation on the edge of the yoga mat. When cutting, if the edge undulates, it will cause the edge of the cut yoga mat to be irregular. Therefore, a prism or frustum-type positioning block is required. The frustum will cause the yoga mat and its conflict position to be a point, not a plane. Therefore, this design adopts a prism design.

[0027] The design of the screw assembly is to save employees' physical energy and reduce fatigue because employees do not need to push the lower template to move. During the stamping and cutting process, the stamping action poses a high risk to the human body. Manually pushing the lower template increases the probability of employees being injured by stamping, and excessive fatigue can make employees dazed and prone to work errors. Therefore, a screw drive method is adopted to improve employee safety performance.

[0028] (2) The cooperation of the guide rod, compression spring and nut is used to adjust the front and rear position of the first positioning block on the lower template. This design is to adapt to different yoga mat products. Because the width specifications of yoga mats are different during the cooling and shaping steps of yoga mat production, there are also many sizes of yoga mats. However, during the production process, sometimes due to the need for expedited orders, some large-sized stock yoga mats will be cut into small areas to meet the customer's needs for fast delivery. Therefore, the first positioning block needs to be adjusted to match the positioning cutting of the large-sized blank yoga mat.

[0029] (3) The anti-collision strip is set to prevent employees from being injured by the movement of the lower template.

[0030] (4) The arrangement of the left positioning block and the right positioning block is used to place the yoga mat more accurately on the lower template. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The following is combined with Figure 1 -Attached Figure 10 The utility model is described in further detail.

[0051] Example 1, a yoga mat punching and cutting device, referring to Figures 1 - 8 Provide explanation;

[0052] Reference Figure 1 -and Figure 2, including a machine base 1, the machine base 1 is provided with an upper template 2 and a lower template 3. A vertical guide post is fixed on the machine base 1, the upper template 2 slides on the guide post, a connecting plate is fixed at the top of the guide post, and a vertical air cylinder is installed on the connecting plate. The vertical air cylinder drives the upper template 2 to move up and down.

[0053] The upper template 2 is provided with a cutting knife 21, and the cutting knife 21 is annular, in the shape of a waist ring or a rectangular ring.

[0054] The lower template 3 is located below the upper template 2. The lower template 3 places the blank yoga mat, and the upper template 2 presses down to perform stamping and cutting on the yoga mat.

[0055] The lower template 3 can move horizontally, and the specific structure is as follows.

[0056] The machine base 1 is provided with two horizontal slide rails 32. The slide rails 32 protrude horizontally from the machine base 1, and the two slide rails 32 are arranged in parallel.

[0057] The outer ends of the two slide rails 32 are connected and fixed with a cross beam 33. The cross beam 33 prevents employees from entering between the two slide rails 32 and ensures the operation safety of employees.

[0058] The lower template 3 slides on the slide rails 32 to achieve the purpose of horizontal sliding.

[0059] The sliding of the lower template 3 is driven by a power component on the machine base 1. The switch of the power component can adopt a foot switch, and the foot switch can be arranged below the slide rails 32 for employees to control.

[0060] Refer to Figures 2 - 4 , in order to avoid the situation that during the process of the lower template 3 moving out, an employee carelessly puts his hand on the moving track of the lower template 3 and causes his hand to be violently hit by the lower template 3, this design adopts an anti-collision strip 71;

[0061] The machine base 1 is provided with a motor 62 for driving the power component, and the motor 62 is installed on the machine base 1;

[0062] The edge of the lower template 3 is provided with an anti-collision strip 71 that shuts down the motor 62 when compressed; the edge of the lower template 3 is provided with a sliding cavity 74, and an emergency stop button 73 is arranged in the sliding cavity 74. The anti-collision strip 71 slides in the sliding cavity 74; a partition component is arranged between the anti-collision strip 71 and the inner wall of the sliding cavity 74 to prevent the anti-collision strip 71 from slipping out of the sliding cavity 74; and a second spring is arranged in the sliding cavity 74 to push the anti-collision strip 71 and the emergency stop button 73 to maintain a gap.

[0063] When an employee's hand collides with the anti-collision strip 71 on the edge of the sliding lower template 3, the anti-collision strip 71 is compressed and moves inward, squeezing the emergency stop button 73. The emergency stop button 73 turns off the motor 62, causing the lower template 3 to move further outwards, thus avoiding the situation where the employee's hand is severely injured by the lower template 3. Its advantages are as follows: the anti-collision strip 71 increases the contact area, which can reduce the pressure when the hand is hit; secondly, the timely shutdown of the motor 62 can stop further impact damage. There is a control line connected between the emergency stop button 73 and the motor 62, and the control line can be installed through a cable drag chain, so that the lower template 3 will not be interfered by the control line during the movement process.

[0064] The outer surface of the anti-collision strip 71 is provided with a flexible strip 72. The flexible strip 72 is a rubber strip, which reduces the impact damage.

[0065] The anti-collision strip 71 is located at the side edge of the lower template 3 and is located in the middle of the two slide rails 32.

[0066] Refer to Figure 5 and Figure 6 and Figure 7 The machine base 1 is provided with a power assembly for pushing the lower template 3 in and out directly below the upper template 2. The power assembly is a lead screw assembly 61. In other embodiments, the power assembly can also be a cylinder or an oil cylinder. The drive of the lead screw assembly 61 is controlled by the motor 62.

[0067] The lead screw assembly 61 includes a lead screw and a slide bar arranged in parallel. The lead screw and the slide bar are respectively located on the two slide rails 32.

[0068] The slide bar is fixed on the slide rail 32, and the lower template 3 is sleeved and slides on the slide bar to achieve the design of directional sliding.

[0069] The lower template 3 is sleeved on the lead screw, and a threaded ring is provided inside the lower template 3. The threaded ring is threadedly connected to the lead screw. Therefore, the forward and reverse rotation of the lead screw can control the back-and-forth movement of the lower template 3.

[0070] Bearing seats are fixed on the slide rails 32, and both ends of the lead screw are fixed on the bearing seats. The motor 62 on the machine base 1 is connected to the lead screw through a coupling. Therefore, the motor 62 can control the forward and reverse rotation of the lead screw.

[0071] When placing the blank yoga mat on the lower template 3, it is placed by the employee by hand. To ensure the accuracy of the placement, the specific structure is as follows.

[0072] Refer to Figures 5 - 8 The lower template 3 is provided with a first positioning block 41 for front-end positioning. The first positioning block 41 protrudes from the upper surface of the lower template 3. The lower template 3 is provided with a mounting block 42. The first positioning block 41 slides vertically in the mounting block 42. The mounting block 42 is provided with a first spring 43 for pushing up the first positioning block 41. The first positioning block 41 is a frustum structure and is located outside the cutting knife 21.

[0073] The lower template 3 is provided with a sliding groove 51, and a guide rod 52 is arranged in the sliding groove 51. The mounting block 42 slides on the guide rod 52. The guide rod 52 is a threaded rod, and a compression spring 53 is sleeved on the guide rod 52. One end of the compression spring 53 abuts against the end of the sliding groove 51, and the other end of the compression spring 53 abuts against the mounting block 42; a nut 54 for positioning and mounting the mounting block 42 is threadedly connected to the guide rod 52; the nut 54 and the compression spring 53 clamp and arrange the mounting block 42. In order to further stabilize the positioning of the mounting block 42, two nuts 54 can be arranged side by side on the guide rod 52.

[0074] The cutting knife 21 is annular. In a top-down view, when the lower template 3 is directly below the upper template 2, the first positioning block 41 is located outside the cutting knife 21.

[0075] The working principle is that the employee places the yoga mat on the moved-out lower template 3 outside the cross beam 33, aligns the front and back positions of the yoga mat with the edge of the yoga mat abutting against the first positioning block 41 as the standard. Then, the lower template 3 is controlled to move directly below the upper template 2, and then the lower template 3 is pressed down, and the cutting knife 21 cuts the edge of the yoga mat.

[0076] During the mold closing process of the upper template 2 and the lower template 3, the first positioning block 41 will be squeezed and moved downward by the upper template 2. And since the first positioning block 41 is a frustum structure, the distance between the first positioning block 41 and the yoga mat becomes larger and larger during the downward movement of the first positioning block 41, avoiding the situation where the side of the first positioning block 41 rubs and pushes the yoga mat.

[0077] Secondly, after loosening the nut 54, the mounting block 42 can move and adjust the front and back positions in the sliding groove 51. Synchronously, the first positioning block 41 also adjusts the front and back positions. When the nut 54 is kept in the set position, due to the thrust of the compression spring 53, the first positioning block 41 can be stably installed at the set position of the guide rod 52.

[0078] Embodiment 2, a yoga mat stamping and cutting device, the difference from Embodiment 1 is that, referring to Figure 9 , there are two first positioning blocks 41. The two first positioning blocks 41 form a straight line, which is more beneficial for the employee to position the front end of the yoga mat.

[0079] Embodiment 3, a yoga mat stamping and cutting device, the difference from Embodiment 1 or Embodiment 2 is that, referring to Figure 10 , a left positioning block 81 is provided on the left side of the lower template 3, and a right positioning block 82 is provided on the right side of the lower template 3. The left positioning block 81 and the right positioning block 82 have the same structure as the first positioning block 41. Therefore, the left positioning block 81 and the right positioning block 82 also have telescopic performance and the function of adjusting the horizontal position distance;

[0080] The left positioning block 81 and the right positioning block 82 are symmetrically arranged on both sides of the first positioning block 41.

[0081] The cooperation of the first positioning block 41, the left positioning block 81 and the right positioning block 82 can make the yoga mat be positioned and placed more accurately.

[0082] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
