Description

Technical Field

[0001] The invention relates to the technical field of label printing, in particular to a label embossing machine. Background Art

[0002] When stamping product labels, a hot stamping machine is generally used. A hot stamping machine is a machine that stamps anti-counterfeiting labels to a specified position by pressing. It is mainly composed of a frame, a heating system, a hot stamping plate, a pressure device and a control system. The hot stamping machine heats the hot stamping plate through the heating system. After reaching a certain temperature, the template is installed under the hot stamping plate, and then the metal foil or thermal transfer ink layer is placed under the hot stamping plate. After ensuring that it is aligned with the substrate, the pressure device starts to work and applies appropriate pressure to the metal foil or thermal transfer ink layer. Under the combined action of heat and pressure, the hot-melt dyed resin layer and adhesive of the metal foil or thermal transfer ink layer melt. At this time, the viscosity of the dyed resin layer decreases, while the viscosity of the special thermal adhesive increases after melting, so that the aluminum layer is peeled off from the electrochemical aluminum base film and transferred to the substrate at the same time. After the pressure and heating are removed, the adhesive quickly cools and solidifies, and the aluminum layer is firmly attached to the substrate.

[0003] During the stamping process, high-temperature glue is generally used to stick the template under the hot stamping plate, and the hot stamping plate is used to heat the template. However, the existing hot stamping plate is heated in a way that the entire hot stamping plate is evenly heated by a resistance wire. Some labels have a relatively small area, and the corresponding template area is also relatively small. When the template is installed on the hot stamping plate, the template only occupies a very small area of ​​the hot stamping plate, which causes a large part of the heat emitted by the hot stamping plate to dissipate in the air, thereby causing energy waste.

[0004] To this end, a label embossing machine is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a label stamping machine. In order to solve the problem that when the heating area of ​​the hot stamping plate is larger than the heating area of ​​the template, the heat of a large area of ​​the hot stamping plate cannot be effectively utilized, resulting in heat waste. The heated area of ​​the hot stamping plate is divided into multiple small parts, and then the heating area of ​​the small part in contact with it is pushed by the template to connect with the heating component to form a heating area similar to the area of ​​the template to heat the template, thereby solving the problem that when the heating area of ​​the hot stamping plate is larger than the heating area of ​​the template, the heat cannot be effectively utilized, resulting in heat waste. At the same time, the edge of the heating area limits the edge of the template, avoiding the template from shifting during stamping, thereby improving the stamping quality.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A label stamping machine comprises a base, a hydraulic component and a template, and also comprises a hot stamping plate, a heating component and a fixed component, wherein the hot stamping plate is connected to the bottom of the hydraulic component, the hot stamping plate comprises an outer shell, a connecting plate, a movable shell, a movable column, a limit plate and a lifting spring, the outer shell is connected to the hydraulic component, the connecting plate is connected to the inside of the outer shell, a plurality of movable columns are slidably connected to the connecting plate, the lifting spring is connected to the outer wall of the movable column, and the top is connected to the bottom of the connecting plate, the limit plate is connected to the inside of the outer shell and is located above the connecting plate, the movable shell is slidably connected to the outer wall of the outer shell and is connected to the limit plate, the fixed component is connected to the outer wall of the movable column, the heating component is connected to the inside of the outer shell and is located above the movable column, when the template is installed, the hot stamping plate is driven downward by the hydraulic component to connect the template to the movable column, the movable column is connected to the heating component under the reverse thrust of the template, and is fixed by the fixed component when the movable column moves upward, and when the stamping is finished, the limit plate is driven by pushing down the movable shell to release the fixation of the fixed component.

[0008] In the existing technology, the hot stamping plate is generally heated by several large thermal resistors. When stamping large product labels, most of the heat source can be utilized. However, when stamping small product labels, since the area of ​​the product label is smaller than the area of ​​the hot stamping plate, the heating area will be larger than the heated area, resulting in heat waste. In this solution, the stamping object is placed on the base, and the template is placed in the area where the stamping object needs to be stamped. The hot stamping plate is pressed down by the hydraulic component to make the template fit with the bottom of the moving column, and the moving column in contact with the template is pushed upward to connect the moving column with the heating component. The heating component is used to heat the moving column moving upward, thereby avoiding heating of the entire hot stamping plate, and making the heating area close to the template area, reducing heat waste.

[0009] Preferably, the movable column comprises an upper column and a lower column, the cross section of the upper column is set to be circular and is slidably connected to the connecting plate and the limiting plate, and the cross section of the lower column is set to be square.

[0010] In the above scheme, the cross-section of the lower cylinder is set to be square rather than circular or other polygonal, because there is a heating blank area at the edge connection of the circular heating surface and other polygonal heating surfaces, and the edges of the square heating surface are in contact with each other, and the heating blank area is smaller than the blank area formed by the circular heating surface and other polygonal heating surfaces, so that the mold is heated more evenly. Although the heating surface composed of triangles and the heating surface composed of squares both have the characteristics of small heating blank areas, the template in the prior art is usually rectangular, and the edge of the square heating surface is in closer contact with the edge of the template than the triangular heating surface.

[0011] Preferably, the upper cylinder and the lower cylinder are hollow, the top of the upper cylinder is connected to a positive contact, the top of the lower cylinder is connected to a negative contact, the lower cylinder is connected to a heating component, the heating component includes an upper electric plate, a lower electric plate and a thermal resistor, the upper electric plate and the lower electric plate are both connected to the inner wall of the outer shell, the upper electric plate is located above the upper cylinder, the lower electric plate is located above the lower cylinder and below the connecting plate, the thermal resistor is connected to the inside of the lower cylinder, the bottom of the upper electric plate and the bottom of the lower electric plate are connected to connecting contacts, the connecting contacts are arranged in a rectangular array, and each column of connecting contacts are connected in parallel, and the connecting contacts respectively cooperate with the positive contact and the negative contact.

[0012] In the above scheme, the negative contact and the positive contact are connected to the connecting contact, and the thermistor inside the movable column forms a loop with the upper power plate and the lower power plate, so that the thermistor is energized and generates heat. The connection between each connecting contact is in parallel, so that the thermistors are also in a parallel relationship, so that the loops between each thermistor do not affect each other, so that each thermistor can generate heat independently.

[0013] Preferably, the fixing assembly includes a fixing plate, a compression spring and a first slide groove, the first slide groove is opened inside the upper column, the compression spring is connected to the middle of the first slide groove, the two fixing plates are connected to the two ends of the first slide groove, the two ends of the compression spring are respectively connected to the fixing plates on both sides, and the upper and lower sides of the fixing plate are respectively matched with the bottom of the limiting plate and the bottom of the connecting plate.

[0014] In the above scheme, when the fixed plate moves to the top of the connecting plate under the drive of the upper column, the fixed plate is moved out of the second slide groove under the push of the compression spring, and the bottom of the fixed plate and the top of the connecting plate are connected, limiting the downward movement of the movable column. At the same time, the upper side of the fixed plate contacts the bottom of the limit plate, thereby limiting the upward movement distance of the movable column, thereby fixing the movable column and avoiding damage caused by excessive pressure between the movable column and the upper and lower power plates.

[0015] Preferably, a second slide groove is provided on the inner wall of the shell, a return spring is connected to the inside of the second slide groove, the limit plate is slidably connected to the second slide groove, and the bottom is connected to the return spring, a second through hole is provided at the bottom of the limit plate, the cross-section of the second through hole is funnel-shaped, and the minimum diameter is the same as the diameter of the upper column, the upper column contacts the upper power plate through the second through hole, the fixed plate is a right-angled trapezoid, the right-angled side of the fixed plate is parallel to the connecting plate, the second through hole cooperates with the hypotenuse of the fixed plate, and the total width of the two fixed plates is greater than the width of the first slide groove.

[0016] In the above scheme, the movable shell is pushed downward to move the limit plate downward, and the fixed plate is squeezed to push the fixed plate into the first slide groove, thereby releasing the fixation of the movable column, and the second through hole is set to a funnel shape, so that the bottom of the second through hole fits better with the side of the fixed plate, thereby making it easier to push the fixed plate into the first slide groove, and the total width of the fixed plate is greater than the width of the first slide groove, so that the fixed plate cannot be completely retracted into the first slide groove, thereby limiting the depth of the fixed plate entering the second through hole, and then limiting the upward movement distance of the movable column, avoiding damage caused by excessive pressure on the upper and lower power plates.

[0017] Preferably, a first through hole is opened on the top of the connecting plate, and the upper column passes through the first through hole, and the diameter of the first through hole is larger than the diameter of the upper column.

[0018] In the above scheme, since the total width of the two fixed plates is greater than the total width of the first slide groove, the fixed plates cannot be completely retracted into the first slide groove, resulting in the overall width of the upper column being greater than the diameter of the upper column. Therefore, the diameter of the first through hole is greater than the diameter of the upper column, so that when the fixed plates are retracted into the first slide groove, the upper column can still move inside the first through hole.

[0019] Preferably, a positioning assembly is connected above the base, and the positioning assembly includes a positioning platform, a positioning plate, a moving block, a telescopic rod and a pressure plate. The positioning platform is slidably connected to the top of the base, the positioning plate is connected to the top of the positioning platform, the moving block is slidably connected to the top of the positioning platform, the telescopic rod is hinged to the base, the pressure plate is connected to the telescopic rod, the cross-section of the pressure plate is set to L-shape, and the edge of the pressure plate is aligned with the edge of the lower column.

[0020] In the above scheme, the imprinting object is positioned by the positioning plate and the moving block to ensure that the imprinting object is aligned with the hot stamping plate and does not tilt. In the prior art, after the imprinted object is positioned, the template is placed in the area to be imprinted, and the position of the template is manually adjusted. It is easy to tilt during adjustment, thereby affecting the quality of imprinting. Therefore, after the imprinting object is positioned, the template is positioned by the pressing plate and the moving block so that the template still maintains the correct position when it contacts the hot stamping plate. At the same time, the edge of the pressing plate is aligned with the edge of the lower column, so that the edge of the template is aligned with the edge of the lower column, and the edge of the template is fit with the edge of the lower column that is not pushed by the template. In the prior art, the template is connected to the hot stamping plate by high-temperature glue. The glue has a certain fluidity and is easy to deviate during imprinting, causing the imprinted label to deviate, thereby affecting the quality of imprinting. In this scheme, the edge of the lower column that is not pushed by the template is fit with the edge of the template, which plays a limiting role on the template, thereby avoiding the deviation of the template during imprinting, thereby improving the quality of imprinting.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By setting up a moving column and a heating component, when the hot stamping plate moves downward and contacts the template, the reverse thrust of the template is used to push the moving column upward and connect with the heating component, so that the moving column that moves upward forms a heating area with an area close to that of the template, avoiding the entire bottom of the hot stamping plate from being heated. Instead, the heating area is adjusted according to the area of ​​the template, thereby reducing energy waste. The edge of the heating area limits the edge of the template, preventing the template from shifting during embossing, thereby improving the embossing quality.

[0023] 2. By setting a fixed plate and a limit plate, when the movable column moves upward, the fixed plate pops out from the second slide groove and contacts with the limit plate and the connecting plate, thereby fixing the movable column and improving the stability of the movable column during the stamping process. At the same time, the limit plate limits the upward movement distance of the movable column by limiting the movement of the fixed plate, thereby avoiding damage caused by excessive pressure between the movable column and the upper and lower power plates.

[0024] 3. By setting up the positioning component, the positioning plate and the moving block in the positioning component are used to position the stamping object, and the template is positioned by the pressing plate to avoid the template from tilting when it contacts the hot stamping plate and affecting the quality of stamping. At the same time, the pressing plate also makes the template flush with the edge of the moving column, so that the edge of the heating area formed by the moving column fits with the edge of the template, avoiding the template from shifting during stamping and affecting the stamping quality.

When the template 3 is installed, the hydraulic component 2 drives the hot stamping plate 4 to move downward so that the template 3 is connected to the movable column 404. The movable column 404 is connected to the heating component 5 under the reverse thrust of the template 3. The heating component 5 is used to heat the movable column 404 moving upward, thereby avoiding heating the entire hot stamping plate 4, thereby reducing heat waste. When the movable column 404 moves upward, it is fixed by the fixed component 6. When the stamping is completed, the movable shell 403 is pushed down to drive the limit plate 405 to release the fixation of the fixed component 6.

[0037] As an embodiment of the present invention, refer to Figure 2 and Figure 3 The movable column 404 includes an upper column 4041 and a lower column 4042. The cross section of the upper column 4041 is set to be circular and is slidably connected to the connecting plate 402 and the limiting plate 405. The cross section of the lower column 4042 is set to be square, so that the edges between the lower columns 4042 fit each other, thereby reducing the heating blank area and making the mold heating more uniform. At the same time, the square heating surface fits better with the edge of the template 3.

[0038] As an embodiment of the present invention, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7, the upper cylinder 4041 and the lower cylinder 4042 are hollow, the top of the upper cylinder 4041 is connected to a positive contact 4043, the top of the lower cylinder 4042 is connected to a negative contact 4044, the lower cylinder 4042 is connected to the heating component 5, the heating component 5 includes an upper electric plate 501, a lower electric plate 502 and a thermal resistor 503, the upper electric plate 501 and the lower electric plate 502 are both connected to the inner wall of the shell 401, the upper electric plate 501 is located above the upper cylinder 4041, the lower electric plate 502 is located above the lower cylinder 4042 and below the connecting plate 402, the thermal resistor 503 is connected to the inside of the lower cylinder 4042, the bottom of the upper electric plate 501 and the bottom of the lower electric plate 502 are both connected to connecting contacts 504, the connecting contacts 504 are arranged in a rectangular array, and each column of connecting contacts 504 is connected in parallel, The connecting contact 504 cooperates with the positive contact 4043 and the negative contact 4044 respectively, and is connected to the connecting contact 504 through the negative contact 4044 and the positive contact 4043, so that the thermal resistor 503 inside the moving column 404 forms a loop with the upper power plate 501 and the lower power plate 502, so that the thermal resistor 503 is energized and generates heat. The connection mode between each connecting contact 504 is parallel, so that the thermal resistors 503 are also in a parallel relationship, so that the loops between each thermal resistor 503 do not affect each other, so that each thermal resistor 503 can generate heat separately. When the connecting contact 504 contacts with the positive contact 4043 and the negative contact 4044, a certain gap will be retained between the connecting contact 504 and the positive contact 4043 and the negative contact 4044, thereby avoiding damage caused by excessive pressure between the connecting contact 504 and the positive contact 4043 and the negative contact 4044.

[0039] As an embodiment of the present invention, refer to Figure 4 and Figure 6 The fixing assembly 6 includes a fixing plate 601, a compression spring 602 and a first slide groove 603. The first slide groove 603 is opened inside the upper column 4041. The compression spring 602 is connected to the middle of the first slide groove 603. The two fixing plates 601 are connected to both ends of the first slide groove 603. The two ends of the compression spring 602 are respectively connected to the fixing plates 601 on both sides. When the fixing plate 601 moves to the top of the connecting plate 402 under the drive of the upper column 4041, the fixing plate 601 is pushed by the compression spring 602. 01 moves out of the second slide groove 4011, and connects the bottom of the fixed plate 601 and the top of the connecting plate 402, limiting the downward movement of the movable column 404. The upper and lower sides of the fixed plate 601 cooperate with the bottom of the limiting plate 405 and the bottom of the connecting plate 402 respectively. At the same time, the upper side of the fixed plate 601 contacts the bottom of the limiting plate 405 to limit the upward movement distance of the movable column 404, thereby fixing the movable column 404 and avoiding damage caused by excessive pressure between the movable column 404 and the upper and lower power plates 501 and 502.

[0040] As an embodiment of the present invention, refer to Figure 4 , Figure 5 and Figure 6 The inner wall of the shell 401 is provided with a second slide groove 4011, and a return spring 4012 is connected inside the second slide groove 4011. The limiting plate 405 is slidably connected to the second slide groove 4011, and the bottom is connected to the return spring 4012. The bottom of the limiting plate 405 is provided with a second through hole 4051, and the cross section of the second through hole 4051 is set to be funnel-shaped, and the minimum diameter is the same as that of the upper column 4041. By pushing the movable shell 403 to move downward, the limiting plate 405 is driven to move downward, squeezing the fixed plate 601, and pushing the fixed plate 601 into the first slide groove 603, thereby releasing the fixation of the movable column 404, and setting the second through hole 4051 to be funnel-shaped, so that the bottom of the second through hole fits better with the side of the fixed plate 601, The upper column 4041 passes through the second through hole 4051 and contacts the upper power board 501. The fixed plate 601 is a right-angled trapezoid. The right-angled side of the fixed plate 601 is parallel to the connecting plate 402. The second through hole 4051 cooperates with the hypotenuse of the fixed plate 601. The total width of the two fixed plates 601 is greater than the width of the first slide groove 603. The total width of the fixed plate 601 is greater than the width of the first slide groove 603, so that the fixed plate 601 cannot be completely retracted into the first slide groove 603, thereby limiting the depth of the fixed plate 601 entering the second through hole 4051, and further limiting the upward movement distance of the movable column 404, thereby avoiding damage to the upper power board 501 and the lower power board 502 due to excessive pressure.

[0041] As an embodiment of the present invention, refer to Figure 4 and Figure 7 A first through hole 4021 is formed on the top of the connecting plate 402, and the upper column 4041 passes through the first through hole 4021. The diameter of the first through hole 4021 is larger than the diameter of the upper column 4041. Since the total width of the two fixing plates 601 is larger than the total width of the first slide groove 603, the fixing plate 601 cannot be completely retracted into the first slide groove 603, resulting in the overall width of the upper column 4041 being larger than the diameter of the upper column 4041. Therefore, the diameter of the first through hole 4021 is larger than the diameter of the upper column 4041, so that when the fixing plate 601 is retracted into the first slide groove 603, the upper column 4041 can still move inside the first through hole 4021.

[0042] As an embodiment of the present invention, refer to Figure 1 and Figure 8A positioning assembly 7 is connected above the base 1, and the positioning assembly 7 includes a positioning platform 701, a positioning plate 702, a moving block 703, a telescopic rod 704 and a pressing plate 705. The positioning platform 701 is slidably connected to the top of the base 1, the positioning plate 702 is connected to the top of the positioning platform 701, and the moving block 703 is slidably connected to the top of the positioning platform 701. The imprinting object is positioned by the positioning plate 702 and the moving block 703 to ensure that the imprinting object is aligned with the hot stamping plate 4 and does not tilt, thereby improving the quality of imprinting. The telescopic rod 704 is hinged to the base 1, and the pressing plate 705 is connected to the telescopic rod 704. The telescopic rod 704 can drive the pressing plate 705 to rotate back and forth. The cross section of the pressing plate 705 is set to be L-shaped. When the imprinting object is positioned After completion, the pressing plate 705 is pressed above the imprinting object by pulling the telescopic rod 704, and the position of the imprinting object is adjusted by pushing the positioning platform 701 and the moving block 703, which indirectly drives the template 3 to move, so that the edge of the template 3 is aligned with the edge of the pressing plate 705, thereby realizing the positioning of the template 3, avoiding the template 3 from being offset when in contact with the hot stamping plate 4, thereby affecting the quality of imprinting, and the edge of the pressing plate 705 is aligned with the edge of the lower column 4042. Because the relative position between the pressing plate 705 and the moving column 404 remains unchanged, the edge of the template 3 is aligned with the edge of the lower column 4042, and the edge of the lower column 4042 that is not pushed by the template 3 is fitted to limit the template 3, thereby avoiding the offset of the template 3 during imprinting, thereby improving the quality of imprinting.

[0043] Working principle: When stamping, first place the stamping object on the positioning plate 702 (refer to Figure 8 ), align its edges with the edges of the positioning plate 702 and the moving block 703, so that the position of the stamping object is kept correct, and then the template 3 is placed in the area where the stamping object needs to be stamped, and then the telescopic rod 704 is rotated and stretched to make the pressing plate 705 fit over the stamping object, and the positioning platform 701 and the moving block 703 are pushed, so that the stamping object drives the template 3 to move, so that the edge of the template 3 fits over the edge of the pressing plate 705, and after determining the position, high-temperature glue is applied to the top of the template 3, and finally the hydraulic component 2 is started to move the hot stamping plate 4 downward to fit the template 3, so as to realize the installation of the template 3, and then the telescopic rod 704 is rotated to separate the pressing plate 705 from the stamping object, and the heating component 5 is started to heat the template 3.

[0044] Since the area of ​​the hot stamping plate 4 is larger than that of the template 3, the heat at the bottom of the hot stamping plate 4 cannot be fully utilized by the template 3, resulting in heat waste. By setting a movable column 404, the template 3 is used to push the movable column 404 upward to connect it with the heating component 5, forming a heating area close to the area of ​​the template 3, so that the heating area matches the heated area, and the heat is fully utilized.

[0045] Specifically, when the hot stamping plate 4 moves downward and contacts the template 3, the template 3 will push the moving column 404 upward, and at the same time, the upper column 4041 drives the fixed plate 601 to move out of the first through hole 4021. When the fixed plate 601 moves out, the fixed plate 601 is pushed out of the first slide groove 603 by the compression spring 602. At this time, the lower side of the fixed plate 601 is connected to the upper side of the connecting plate 402, and the upper side of the fixed plate 601 is connected to the lower side of the limiting plate 405, so that the heated moving column 404 is fixed. When the moving column 404 moves upward, it will drive the positive contact 4043 and the negative contact 4044 to move upward, and connect with the connection contacts 504 at the bottom of the upper and lower plates 501 and 502, so that they form a parallel circuit with multiple thermal resistors 503, and then form a heating area similar to the area of ​​the template 3 through the upward moving column 404.

[0046] Since the edge of the pressing plate 705 fits with the edge of the movable column 404, when the template 3 contacts the bottom of the movable column 404, the edge of the template 3 also fits with the edge of the movable column 404 that has not moved up, thereby limiting the edge of the template 3 and avoiding the template 3 from shifting during stamping, thereby improving the stamping quality. After the installation is completed, the hydraulic assembly 2 is started to drive the hot stamping plate 4 to move downward. When the hot stamping plate 4 moves downward, it drives the template 3 to move downward to stamp the stamping object.
