Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and more specifically to a novel blanket printing equipment. Background Technology

[0002] Blankets are a common bedding item with warmth-retaining properties. Their raw materials are mostly animal fibers (such as wool, mohair, rabbit hair, cashmere, camel hair, and yak wool) or chemical fibers such as acrylic and viscose fibers. Some are blends of animal and chemical fibers. Printing is a process of applying patterns to textiles using dyes or pigments. Printing can be categorized into fabric printing, yarn printing, and thread printing, with fabric printing being the most common. Roller printing is one of the most common methods for printing on blankets. Chinese patent (CN209888396U) discloses a "novel blanket printing device," which includes two sets of supporting side plates arranged vertically parallel to each other. Limiting grooves are formed on the side walls of the supporting side plates, and positioning sliders are engaged within the inner cavity of these grooves. This invention uses a positioning shaft to fix the printing roller between the two sets of positioning sliders. By adjusting the positions of the two sets of positioning sliders in the limiting grooves, the printing height of the printing roller can be adjusted, thus facilitating the printing roller to print on blankets of different thicknesses.

[0003] However, the printing roller still has defects when adjusting its height: for example, the roller is prone to tilting during the adjustment process. That is, the height adjustment mechanisms at both ends of the roller are independent mechanisms and cannot be linked and operated synchronously. This causes distance errors to easily occur when the two ends of the roller are adjusted synchronously, affecting the normal operation of the roller. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a novel blanket printing device to solve the problem that the printing pressure roller is prone to tilting when the height is adjusted in the traditional device mentioned in the background art.

[0005] This utility model provides the following technical solution: a novel blanket printing device, comprising a lifting and adjusting frame assembly and a printing pressure roller. The lifting and adjusting frame assembly includes two upright frames, each with a rail groove and an accessory groove on its side wall. A sealing plate is fixedly installed on both sides of each upright frame, the sealing plate being used to close the accessory groove. A threaded shaft is rotatably sleeved within each of the two rail grooves, and a sliding component is slidably sleeved within each of them. The sliding component is threaded onto the side wall of the threaded shaft. A transmission assembly is installed in each of the two accessory grooves. The top ends of the two threaded shafts penetrate into the two accessory grooves and respectively connect with the two transmission assemblies. A connecting rod assembly is provided on the inner side of each of the two upright frames. Both ends of the connecting rod assembly penetrate the sealing plate and respectively connect with the two transmission assemblies. A motor is installed on the side wall of one sealing plate, the motor output shaft penetrating the sealing plate and connecting with one transmission assembly. The printing pressure roller is rotatably sleeved on the inner side of the two sliding components.

[0006] Furthermore, the sliding component includes a slider, a side block is fixedly connected to one side of the slider, a columnar groove is provided on the top of the side block, an ear block is slidably sleeved in the columnar groove, the side wall of the ear block is used to install the printing pressure roller, a top plate is fixedly connected to the top of the inner wall of the columnar groove of the side block, the bottom of the top plate is connected to the top of the ear block through a spring, and the slider is threadedly sleeved on the side wall of the threaded shaft.

[0007] Furthermore, a central column is fixedly connected inside the columnar groove, the spring is sleeved on the side wall of the central column, and the ear block is slidably sleeved on the side wall of the central column.

[0008] Furthermore, the ear block is configured in an L-shape.

[0009] Furthermore, the connecting rod assembly includes a central rod and two side posts. Each of the two side posts has a shaft groove inside, and an inner block is slidably sleeved in each of the two shaft grooves. The two ends of the central rod pass through the shaft grooves of the two side posts respectively and are fixedly connected to the end faces of the two inner blocks.

[0010] Furthermore, the inner block is polygonal, and the cross-section of the axial groove of the side post is polygonal and adapted to the inner block.

[0011] Furthermore, the transmission assembly includes a rotating column, the two ends of which are rotatably sleeved on the inner sides of two sealing plates. A driving bevel gear is fixedly connected to the side wall of the rotating column, and a driven bevel gear meshes with the side wall of the driving bevel gear. The top end of the threaded shaft is fixedly connected to the bottom of the driven bevel gear. One end of the connecting rod assembly is connected to one end of the rotating column, and the motor output shaft is connected to the other end of the rotating column.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention, by setting up a lifting and adjusting frame assembly, can achieve single-power, synchronous and same-speed lifting and adjusting of both ends of the printing roller. Compared with the traditional method of setting two independent height adjustment structures to adjust the two ends of the printing roller independently, it can improve the convenience of adjusting the height of the printing roller and avoid the printing roller from tilting during the adjustment process. In addition, the sliding parts of the lifting and adjusting frame assembly have been structurally optimized so that the printing roller can achieve a pressure self-adaptive effect during the printing process on the blanket, avoiding excessive pressure on the blanket and thus preventing damage to the blanket fibers, which is conducive to improving the product processing qualification rate.

[0020] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Reference Figure 1 and Figure 2 This utility model provides a novel blanket printing device, including a lifting and adjusting frame assembly 1 and a printing pressure roller 2. The lifting and adjusting frame assembly 1 includes two upright frames 11, each with a rail groove 12 and an accessory groove 13 on its side wall. A sealing plate 16 is fixedly installed on both sides of each upright frame 11 to close the accessory groove 13. A threaded shaft 14 is rotatably sleeved in each of the two rail grooves 12, and a sliding member 15 is slidably sleeved in each. The sliding member 15 is threaded onto the side wall of the threaded shaft 14. Each accessory slot 13 is equipped with a transmission component 19. The top ends of the two threaded shafts 14 penetrate into the two accessory slots 13 and are respectively connected to the two transmission components 19. The inner sides of the two upright frames 11 are provided with connecting rod assemblies 17. The two ends of the connecting rod assemblies 17 penetrate the sealing plates 16 and are respectively connected to the two transmission components 19. A motor 18 is installed on the side wall of one sealing plate 16. The output shaft of the motor 18 penetrates the sealing plate 16 and is connected to one transmission component 19. The printing pressure roller 2 is rotated and sleeved on the inner sides of the two sliding parts 15.

[0022] In use, the motor 18 provides rotational power, which in turn drives a single transmission component 19. With the connection of the connecting rod assembly 17, the power can be transmitted, so that the two transmission components 19 can operate synchronously and at the same speed. When the two transmission components 19 are operating, they can simultaneously drive the two threaded shafts 14 to rotate. With the cooperation of the threaded structure, the two sliding parts 15 can move up and down synchronously, thereby adjusting the height of the printing roller 2. In this way, the printing roller 2 can be raised and lowered synchronously at both ends by a single power control, avoiding the skewed state of the printing roller 2 caused by the traditional adjustment method.

[0023] Reference Figure 3 The sliding component 15 includes a slider 151, a side block 152 fixedly connected to one side of the slider 151, a columnar groove 154 provided on the top of the side block 152, an ear block 153 slidably sleeved in the columnar groove 154, the side wall of the ear block 153 is used to install the printing pressure roller 2, a top plate 155 is fixedly connected to the top of the inner wall of the columnar groove 154 of the side block 152, the bottom of the top plate 155 is connected to the top of the ear block 153 through a spring 157, and the slider 151 is threadedly sleeved on the side wall of the threaded shaft 14.

[0024] This setting allows the ear block 153 to have upward displacement space, meaning that the printing roller 2 has a certain upward displacement space during operation. When the height of the printing roller 2 is too low, it is easy to put too much pressure on the blanket during the printing process. When the pressure is too high, it may damage the blanket fibers and affect the product quality. Therefore, through this structural setting, when the printing roller 2 applies too much pressure to the blanket, its reaction force causes the printing roller 2 to move upward, thereby protecting the blanket.

[0025] Reference Figure 3 A central column 156 is fixedly connected inside the columnar groove 154, a spring 157 is sleeved on the side wall of the central column 156, and an ear block 153 is slidably sleeved on the side wall of the central column 156.

[0026] By setting the central column 156, on the one hand, the lug 153 is prevented from falling out of the columnar groove 154, and the stability of the lug 153 during displacement is also improved. On the other hand, the central column 156 positions the spring 157, preventing the spring 157 from bending or falling out of the columnar groove 154 when compressed.

[0027] Reference Figure 3 Ear block 153 is set to L shape.

[0028] By designing the shape of the ear block 153, the longitudinal position of the printing roller 2 can be changed, thereby causing the printing roller 2 to be misaligned with the connecting rod assembly 17, thus preventing the printing roller 2 from colliding with the connecting rod assembly 17 when the height of the printing roller 2 is adjusted too high.

[0029] Reference Figure 4The connecting rod assembly 17 includes a central rod 173 and two side posts 171. Each of the two side posts 171 has a shaft groove inside, and an inner block 172 is slidably sleeved in each of the two shaft grooves. The two ends of the central rod 173 pass through the shaft grooves of the two side posts 171 respectively, and are fixedly connected to the end faces of the two inner blocks 172.

[0030] Through the above structural design of the connecting rod assembly 17, the connecting rod assembly 17 has a telescopic effect, and its length can be adjusted to adapt to the distance between the two upright frames 11.

[0031] Reference Figure 4 The inner block 172 is set to a polygonal shape, and the shaft groove section of the side post 171 is set to a polygonal shape and is adapted to the inner block 172.

[0032] This configuration allows one side post 171 to rotate synchronously with another side post 171 by means of the bearing and the shape matching of the inner block 172, thus preventing the connecting rod assembly 17 from spinning.

[0033] Reference Figure 5 The transmission assembly 19 includes a rotating column 191, with both ends of the rotating column 191 rotatably sleeved on the inner sides of two sealing plates 16. A driving bevel gear 192 is fixedly connected to the side wall of the rotating column 191, and a driven bevel gear 193 meshes with the side wall of the driving bevel gear 192. The top end of the threaded shaft 14 is fixedly connected to the bottom of the driven bevel gear 193. One end of the connecting rod assembly 17 is connected to one end of the rotating column 191, and the output shaft of the motor 18 is connected to the other end of the rotating column 191.

[0034] When the motor 18 outputs power, it drives the rotating column 191 to rotate. The rotating column 191 can drive the connecting rod assembly 17 and the active bevel gear 192 to rotate. Through the meshing relationship between the active bevel gear 192 and the passive bevel gear 193, the threaded shaft 14 can rotate, thereby achieving the transmission effect of the transmission assembly 19.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
