Description

Technical Field

[0001] This utility model belongs to the field of waterproof membrane production technology, specifically, it relates to a printing device for waterproof membrane production. Background Art

[0002] The prior art (application number: CN201821082351.1) discloses a secondary roll printing device for waterproof roll material, which includes a frame; a first conveying drum and a second conveying drum installed on the frame; a rolling drum located on the second conveying drum, the two ends of the rolling drum being driven by a drive assembly to move closer to or further away from the rolling drum; and a printing assembly disposed on the frame, the printing assembly having a lower printing roller and a movable upper roller.

[0003] This prior art uses a rotating roller within its device to contact the wall surface of the waterproof membrane, thereby achieving printing on the waterproof membrane. Printing on waterproof membranes is an essential process in their production, as it not only enhances their appearance but also strengthens their stability. However, there are many types of waterproof membranes on the market, and their different structures result in varying thicknesses. Since the roller in this prior art cannot be adjusted in height, over-printing occurs when printing on thicker waterproof membranes, potentially damaging their structure and weakening their waterproofing effect. Therefore, this prior art can only print on waterproof membranes of a specific size, limiting its applicability.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A printing device for producing waterproof roll material includes a frame and a printing roller. The printing roller is movably connected to the top of the frame. The top of the frame is provided with an adaptive structure, which includes an elastic block and a sliding block. The elastic block and the sliding block are elastically connected. The elastic block is fixedly connected to the top of the frame. The sliding block and the printing roller are movably connected. The adaptive structure can automatically adjust the height of the printing roller.

[0007] In a preferred embodiment of this utility model, the adaptive structure further includes a rebound block, a sliding rod, a sliding block, a positioning slider, a locking rod, a sliding groove, a connecting groove, a locking groove, a baffle, an adaptive groove, and an anti-detachment plate. The adaptive groove is formed on the side wall of the elastic block, the rebound block is in the adaptive groove, the top of the rebound block is elastically connected to the top of the elastic block, the bottom of the rebound block is fixedly connected to the sliding rod, the bottom of the sliding rod is fixedly connected to the sliding block, the wall of the positioning slider is formed through the sliding groove, the positioning slider is slidably connected to the sliding rod through the sliding groove, the connecting groove is formed on the wall of the sliding block, the locking groove is formed on the wall of the locking groove, the locking rod is in the locking groove and slidably connected to the sliding block, the anti-detachment plate is fixedly connected to the positioning slider, and the baffle is fixedly connected to the wall of the elastic block.

[0008] In a preferred embodiment of this utility model, the rebound block can slide within the adaptive groove, and the length of the baffle is half that of the adaptive groove.

[0009] In a preferred embodiment of this utility model, the sliding groove is adapted to the sliding rod, and two sliding grooves are opened through the wall of the positioning slider. The sliding grooves are symmetrically distributed on the wall of the positioning slider, and the number and position of the sliding rods on the wall of the sliding block are consistent with the sliding grooves.

[0010] In a preferred embodiment of this utility model, the wall dimension connecting the anti-detachment plate and the positioning slider is equal to the corresponding wall dimension of the positioning slider plus the sliding block. The wall surface of the anti-detachment plate is also provided with a locking groove, which is adapted to the locking rod, and the locking rod is in the shape of a rectangular column.

[0011] In a preferred embodiment of this utility model, the sliding block is movably connected to an interconnecting block, the interconnecting block is fixedly connected to a rotating motor, and the other end of the rotating motor is rotatably connected to the printing roller.

[0012] In a preferred embodiment of this utility model, the wall of the interconnecting block is inverted L-shaped, the connecting groove is adapted to the interconnecting block, the interconnecting block is slidably connected to the sliding block through the connecting groove, and the adaptive structure, the interconnecting block and the rotating motor are symmetrically arranged at both ends of the printing roller.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The adaptable structure enables printing on waterproof membranes of varying thicknesses because the springs within the device push the printing rollers close to the membrane's surface. When dealing with thicker waterproof membranes, the springs in this solution will spring back to accommodate the thickness. Compared to existing technologies where the internal rollers cannot be adjusted, this solution has a wider range of applications because it can adapt to waterproof membranes of different thicknesses.

[0015] 2. By setting up a detachable interconnecting block, when the printing roller needs to be replaced, it is only necessary to separate the locking rod from the locking groove and then slide the positioning slider along the slide bar to disassemble and replace the printing roller. Compared with the existing technology where the roller cannot be replaced, which requires the purchase of another machine to print different patterns on the wall of the waterproof membrane, this solution only requires disassembling and replacing the printing roller. This solution has a wider range of applications.

[0016] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0024] like Figure 1 and Figure 2 As shown, a printing device for producing waterproof membrane includes a frame 20 and a printing roller 42. The printing roller 42 is movably connected to the top of the frame 20. The frame 20 can place the device in the desired position. The printing roller can apply pressure to the surface of the waterproof membrane to form a special pattern on the wall of the waterproof membrane. This is prior art and will not be described in detail here.

[0025] like Figure 1 and Figure 2As shown, the top of the frame 20 is provided with an adaptive structure, which includes an elastic block 30 and a sliding block 33. The elastic block 30 and the sliding block 33 are elastically connected. The elastic block 30 is fixedly connected to the top of the frame 20, and the sliding block 33 is movably connected to the printing roller 42. The adaptive structure can automatically adjust the height of the printing roller 42. The adaptive structure applies pressure to the sliding block 33 through a spring set inside the elastic block 30, which enables printing on waterproof rolls of different thicknesses.

[0026] like Figure 3 As shown, the adaptive structure also includes a spring block 31, a slide rod 32, a sliding block 33, a positioning slider 34, a locking rod 35, a slide groove 36, a connecting groove 37, a locking groove 38, a baffle 39, an adaptive groove 43, and an anti-detachment plate 44. The adaptive groove 43 is formed on the side wall of the elastic block 30. The spring block 31 is located in the adaptive groove 43. The top of the spring block 31 is elastically connected to the top of the elastic block 30. The bottom of the spring block 31 is fixedly connected to the slide rod 32. The bottom of the slide rod 32 is fixedly connected to the sliding block 33. The wall of the positioning slider 34 has a slide groove 36 that extends through it. The positioning slider 34 is slidably connected to the slide rod 32 through the slide groove 36. The connecting groove 37 is formed on the wall of the sliding block 33. The locking groove 38 is formed on the wall of the locking groove 38. The locking rod 35 is used for locking. The anti-detachment plate 44 and the positioning slider 34 are fixedly connected in the groove 38 and the sliding block 33. The baffle 39 is fixedly connected to the wall of the elastic block 30. The rebound block 31 can slide in the adaptive groove 43. The length of the baffle 39 is half of the adaptive groove 43. The sliding groove 36 is adapted to the sliding rod 32. The wall of the positioning slider 34 has two sliding grooves 36 through it. The sliding grooves 36 are symmetrically distributed on the wall of the positioning slider 34. The number and position of the sliding rods 32 on the wall of the sliding block 33 are the same as those of the sliding grooves 36. The wall size of the anti-detachment plate 44 and the positioning slider 34 is equal to the corresponding wall size of the positioning slider 34 plus the sliding block 33. The wall of the anti-detachment plate 44 is also provided with a locking groove 38. The locking groove 38 is adapted to the locking rod 35. The locking rod 35 is rectangular columnar.

[0027] In practical use, the rotating motor 41 is electrically connected to the power supply. The rotating motor 41 will cause the printing roller 42 to rotate. The spring block 31 is connected to the elastic block 30 through the spring. When the spring block 31 is pushed by the spring, it can drive the slide bar 32. The slide bar 32 will drive the sliding block 33. The sliding block 33 will drive the interconnecting block 40. The interconnecting block 40 will drive the printing roller 42 to move simultaneously.

[0028] In summary, by setting an adaptive structure, printing can be applied to waterproof membranes of different thicknesses. This is because the spring in this device can push the printing roller 42 close to the wall of the waterproof membrane to print on it. When dealing with thicker waterproof membranes, the spring in this solution will rebound to adapt to the thicker waterproof membrane. Compared with the prior art, which cannot adjust its internal roller, this solution has a wider range of applications because it can adapt to waterproof membranes of different thicknesses.

[0029] like Figure 4 As shown, the sliding block 33 is movably connected to the interconnecting block 40, the interconnecting block 40 is fixedly connected to the rotating motor 41, the other end of the rotating motor 41 is rotatably connected to the printing roller 42, the wall of the interconnecting block 40 is inverted L-shaped, the connecting groove 37 is adapted to the interconnecting block 40, and the interconnecting block 40 is slidably connected to the sliding block 33 through the connecting groove 37. The adaptive structure, the interconnecting block 40 and the rotating motor 41 are symmetrically arranged at both ends of the printing roller 42.

[0030] In actual use, the interlocking block 40 will be stuck inside the connecting groove 37, the anti-detachment plate 44 will block the wall of the sliding block 33 to prevent the interlocking block 40 from detaching from the connecting groove 37, and the locking rod 35 passes through the locking groove 38 of the anti-detachment plate 44 and the sliding block 33 to fix the anti-detachment plate 44 to the wall of the sliding block 33.

[0031] In summary, by setting up a detachable interconnecting block 40, when it is necessary to replace the printing roller 42, it is only necessary to separate the locking rod 35 from the locking groove 38 and then slide the positioning slider 34 along the sliding rod 32 to disassemble and replace the printing roller 42. Compared with the existing technology where the roller cannot be replaced, which requires the purchase of another machine to print different patterns on the wall of the waterproof membrane, this solution only requires disassembling and replacing the printing roller 42. This solution has a wider range of applications.

[0032] Working principle: Rotating the motor 41 will cause the printing roller 42 to rotate. The spring block 31 is connected to the elastic block 30 through the spring. When the spring block 31 is pushed by the spring, it can drive the slide bar 32. The slide bar 32 will drive the sliding block 33. The sliding block 33 will drive the interconnecting block 40. The interconnecting block 40 will drive the printing roller 42 to move simultaneously.

[0033] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
