Description

Technical Field

[0001] The present invention relates to the technical field of calendering equipment, in particular to a production device for a graphene-modified foamed floor heating reflective film material. Background Art

[0002] By utilizing the thermal insulation, cushioning, sound absorption, formability and environmental protection properties of graphene-modified foam materials and combining them with reflective films, a new type of graphene-modified foam material floor heating reflective film can be formed.

[0003] During the calendering production process of graphene-modified foamed materials, the tension on the graphene-modified foamed materials in the length direction (calendering conveying direction) is greater than the tension on the width direction, and the graphene-modified foamed materials are in a high temperature state during the calendering process. This causes the two ends in the width direction to shrink inward after leaving the roller, resulting in inconsistent thickness in the middle and thickness on both sides of the width direction of the graphene-modified foamed materials. In order to ensure thickness consistency, multi-stage calendering is generally adopted for calendering, which leads to more calendering processes and reduced efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a graphene-modified foamed floor heating reflective film material production device, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a graphene modified foamed floor heating reflective film material production equipment, comprising a calender for calendering a graphene reflective film blank, a flat belt conveyor arranged at the calender outlet and used to convey the graphene reflective film blank, and a force-adding mechanism that applies a width-direction tensioning force to the reflective film blank during the conveying process, the flat belt conveyor comprising a frame and a belt, a column being provided on the surface of the belt, and a transmission rack arranged along the conveying direction being fixed on both outer facades of the frame; the force-adding mechanism comprises an Mounting slide, one end of the mounting slide is fixed with a support beam, a frame is mounted on the support beam, a driving column and a transmission column are rotatably mounted on the frame, the driving column and the transmission column are transmission-connected together, a driving wheel is fixedly sleeved on the outer surface of the transmission column, a force-adding wheel is transmission-connected below the driving wheel, and the force-adding wheel is rotatably mounted on the frame below the support beam through an axle rod; one end of the driving column away from the transmission column passes through the mounting slide and is fixedly connected with a driving gear, which is meshed with a transmission rack; the mounting slide is slidably mounted on the frame, and the mounting slide sleeve is arranged on the surface of the column;

[0006] The force-applying mechanism also includes a stud and a screw sleeve. One end of the stud is fixedly connected to the frame, and the other end is threadedly provided with a screw sleeve. One end of the screw sleeve is embedded in the mounting slide and rotates with the mounting slide, and the other end is transmission-connected to the prism. The frame is slidably mounted on the surface of the support beam, and an interlocking structure is formed between the frame and the support beam.

[0007] It also includes two vertical circulation rails, which are respectively installed at both ends of the frame along the conveying direction, and the two sets of force-applying mechanisms move correspondingly on the two vertical circulation rails; a reset rack is respectively installed on the upper part of the two vertical circulation rails, and the reset rack is engaged with the driving gear.

[0008] Preferably, the driving column includes a cylinder and a prism, one end of the cylinder passes through and rotates to connect the frame, and the other end is connected to the driving column through a right-angle transmission mechanism, one end of the prism is inserted into the cylinder, and the other end passes through and rotates to connect the mounting slide through a bearing, and the prism is coaxially fixed with the driving gear.

[0009] Preferably, two groups of force adding mechanisms are provided, and are slidably mounted on the top of the frames on both sides of the belt respectively. Each group of force adding mechanisms is provided with a plurality of force adding mechanisms, and are spaced apart along the conveying direction.

[0010] Preferably, two groups of columns are provided, each group of columns is provided with a plurality of columns, and the columns are evenly spaced along the rotation direction of the belt.

[0011] Compared with the prior art, the present invention provides a graphene-modified foamed floor heating reflective film material production device, which has the following beneficial effects:

[0012] 1. The force wheel rolls on the surface of the rolled graphene reflective film blank after rolling, and the force wheel moves with the movement of the graphene reflective film blank, which can apply tension in the width direction of the graphene reflective film blank without affecting the tension in the length direction of the graphene reflective film blank; by making the force wheel move toward the edge in the width direction of the graphene reflective film blank during rotation, the edge of the graphene reflective film blank can be flattened from the inside out, which further reduces or even avoids edge shrinkage, thereby ensuring that the edge thickness and middle thickness of the graphene reflective film blank are consistent, thereby reducing the number of rolling times.

[0013] 2. By setting up two groups of force-adding mechanisms, a symmetrical tensioning force can be formed in the width direction. By providing multiple force-adding mechanisms in each group and allowing them to circulate along the vertical circulating track, the graphene reflective film blank just out of the calender can match the corresponding force-adding mechanism, thereby achieving tensioning of the edges of each width during the calendering production of the graphene reflective film blank and ensuring consistency of edge thickness.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 7 A graphene-modified foamed floor heating reflective film material production device includes a calender 1 for calendering a graphene reflective film blank 11, a flat belt conveyor 2 arranged at the outlet of the calender 1 and used to convey the graphene reflective film blank 11, and two sets of force-applying mechanisms 3 for applying width-direction tensioning force to the reflective film blank during conveying. The two sets of force-applying mechanisms 3 are symmetrically arranged along the central axis in the conveying direction.

[0024] The flat belt conveyor 2 includes a frame 21 and a belt 22. Two groups of columns 23 are provided on the surface of the belt 22. The ends of the columns 23 away from the belt 22 are contracted into a frustum shape. A transmission rack 24 arranged along the conveying direction is fixed on both outer surfaces of the frame 21.

[0025] The cam 33 is provided with a plurality of support rods 34 on the support rod 31, and the support rods 35 are provided with a plurality of support rods 35 on the support rod 31. The support rods 35 are provided with a plurality of support rods 35 on the support rod 31. The support rods 35 are provided with a plurality of support rods 35 on the support rod 31. The support rods 35 are provided with a plurality of support rods 35 on the support rod 31. When the graphene reflective film blank 11 is transported by the belt 22, the mounting slide 31 is driven to move by the column 23, so that the mounting slide 31 moves downstream along the frame 21, driving the force-adding wheel 352 and the graphene reflective film blank 11 to move downstream synchronously. In this process, the driving gear 36 rolls on the transmission rack 24, and drives the transmission column 35 to rotate through the driving column 34, so that the driving wheel 351 drives the force-adding wheel 352 to rotate. The rotation of the force-adding wheel 352 applies tension in the width direction to the graphene reflective film blank 11, thereby reducing the shrinkage deformation of the graphene reflective film blank 11 in the width direction.

[0026] As a further illustration of the above technical solution, the frame 33 is slidably mounted on the surface of the support beam 32, and an interlocking structure is formed between the frame 33 and the support beam 32, so that the frame 33 slides along the length direction of the support beam 32; the drive column 34 includes a cylinder 341 and a prism 342, one end of the cylinder 341 passes through and rotates to connect to the frame 33, and the other end is connected to the drive column 35 through a right-angle transmission mechanism, one end of the prism 342 is inserted into the cylinder 341 and forms a transmission fit with the cylinder 341 that can slide mutually along the axial direction, and the other end passes through and rotates to connect to the mounting slide 31 through a bearing, and the prism 342 is coaxially fixed with the drive gear 36; the drive gear 36 rotates, driving the prism 342 to rotate, thereby driving the cylinder 341 to rotate, thereby realizing the action of the right-angle transmission mechanism. It should be noted that the right-angle transmission mechanism provided in this embodiment is composed of two mutually matching bevel gears, which are fixedly sleeved on the surface of the cylinder 341 and the surface of the transmission column 35 respectively.

[0027] The force-applying mechanism 3 further includes a stud 37 and a screw sleeve 371. One end of the stud 37 is fixedly connected to the frame 33, and the other end is threadedly provided with a screw sleeve 371. One end of the screw sleeve 371 is embedded in the mounting slide 31 and rotates with the mounting slide 31. The other end is connected to the prism 342 via a gear transmission mechanism. The prism 342 drives the screw sleeve 371 to rotate through the gear transmission mechanism, pulling the stud 37, thereby driving the frame 33 to slide on the support beam 32. It should be noted that the gear transmission mechanism is composed of a transmission wheel 1 372 and a transmission wheel 2 373 that match each other.

[0028] Through the above-mentioned structure, when the driving gear 36 rolls on the transmission rack 24, the frame 33 slides toward the side of the mounting slide 31, so that the force-adding wheel 352 moves toward the edge in the width direction of the graphene reflective film blank 11 while rotating. This can further reduce the shrinkage of the graphene reflective film blank 11 in the width direction, and play a role in thinning the edge of the graphene reflective film blank 11, so that the edge thickness of the graphene reflective film blank 11 is consistent with the middle thickness.

[0029] It should be noted that, since a single force-applying mechanism 3 applies tensioning force to the graphene reflective film blank 11 while moving downstream with the graphene reflective film blank 11, the graphene reflective film blank 11 that has just come out of the calender 1 also requires a corresponding force-applying mechanism 3 to be tensioned in the width direction. Therefore, in this embodiment, each group of force-applying mechanisms 3 is provided with multiple ones, and they are spaced apart along the conveying direction, and each group of columns 23 is provided with multiple ones, and they are evenly spaced apart along the rotation direction of the belt 22; after moving to the downstream, each force-applying mechanism 3 can move back to the upstream to cooperate with the graphene reflective film blank 11 that has just come out of the calender 1.

[0030] To enable the urging mechanism 3 to circulate between the upstream and downstream sides, this embodiment further includes two vertical circulating rails, mounted at either end of the frame 21 along the conveying direction. The two sets of urging mechanisms 3 correspondingly move along the two vertical circulating rails. A reset rack 9 is mounted on the upper portion of each vertical circulating rail. The reset rack 9 meshes with the drive gear 36 to restore the distance between the urging wheel 352 and the mounting slide 31 to its initial state when the urging mechanism 3 moves on the upper portion of the vertical circulating rails.

[0031] As a further illustration of the above technical solution, Figure 4 As shown, the vertical circulating track includes a circulating track 4, a driving mechanism 1 5, a driving mechanism 2 6 and a driving mechanism 3 7.

[0032] The circulating track 4 includes a column 1 41, a lower guide rail 44 and a column 2 42 which are sequentially installed on the frame 21 along the conveying direction. The tops of the column 1 41 and the column 2 42 are commonly connected and fixed with a connecting beam 43, and an upper guide rail 45 is fixed to the lower surface of the connecting beam 43. An inclined trough frame 1 46 and an inclined trough frame 2 47 are respectively fixed on the opposite surfaces of the column 1 41 and the column 2 42, and the inclined trough frame 1 46 and the inclined trough frame 2 47 are arranged in a V shape; a positioning guide rail 10 is arranged between the upper guide rail 45 and the lower guide rail 44, and the positioning guide rail 10 is connected and fixed to the connecting beam 43 through a suspension rod 8.

[0033] The driving mechanism 5 includes a driver 51 fixed to the top of the column 41, the output end of the driver 51 is downward and fixedly connected to the connecting rail 52, a slider 53 is slidably installed on the surface of the connecting rail 52, one end of the slider 53 is fixed to a guide post 531, and the guide post 531 is slidably set in the groove of the inclined groove frame 46; the driver 51 drives the connecting rail 52 to move, so that the connecting rail 52 has a first position and a second position. In the first position, the connecting rail 52 cooperates with the upper guide rail 45, and the slider 53 is in a position away from the upper guide rail 45, as shown in FIG. Figure 6 As shown, in the second position, the connecting rail 152 cooperates with the positioning rail 10, and the slider 153 is close to the positioning rail 10. Figure 7 shown.

[0034] The driving mechanism 2 6 includes a driver 2 61 fixed to the top of the column 2 42, the output end of the driver 2 61 is downwardly directed and fixedly connected to the seat plate 62, a connecting rail 2 63 is slidably mounted on the surface of the seat plate 62, one end of the connecting rail 2 63 is fixed to a guide post 2 631, and the guide post 2 631 is slidably arranged in the groove of the inclined slot frame 2 47; the driver 2 61 drives the seat plate 62 to move, so that the connecting rail 2 63 has a third position and a fourth position. In the third position, the connecting rail 2 63 cooperates with the guide rail 45, as shown in FIG. Figure 7 As shown, in the fourth position, the connecting rail 2 63 cooperates with the lower guide rail 44, as shown in FIG. Figure 6 shown.

[0035] Driving mechanism three 7 is a linear motor module. The mobile end of the linear motor module drives the connecting frame 33 and the support beam 32. When the linear motor module pushes the force-adding mechanism 3 to move from driving mechanism two 6 to driving mechanism one 5, the mobile end first drives the connecting frame 33. After the force-adding wheel 352 moves and resets, the mobile end then drives the connecting support beam 32.

[0036] The bottom of the mounting slide 31 is provided with a slide groove 1 311 and a slide groove 2 312 which are interconnected, and the top of the mounting slide 31 is provided with a slide groove 313. The mounting slide 31 cooperates with the lower guide rail 44 through the slide groove 1 311, and the mounting slide 31 cooperates with the connecting rail 2 63 through the slide groove 2 312. The mounting slide 31 cooperates with the upper guide rail 45, the connecting rail 1 52 and the positioning guide rail 10 through the slide groove 313.

[0037] In the process of the force-adding mechanism 3 moving from the upstream of the flat belt conveyor 2 to the downstream of the flat belt conveyor 2 and then back to the upstream of the flat belt conveyor 2 along the vertical circulation guide rail, the installation slide 31 slides between the positioning guide rail 10 and the lower guide rail 44, and slides to the connecting rail 2 63 downstream. The driver 2 61 pulls up the connecting rail 2 63 to move the installation slide 31 upward, so that the connecting rail 2 63 moves upward along the inclined slot frame 2 47. The slide slot 313 is opposite to the upper guide rail 45, and the linear motor module moves the installation slide 31 is pushed onto the upper guide rail 45, and the installation slide 31 slides along the upper guide rail 45 toward the connecting rail 1 52 until it slides onto the connecting rail 1 52 and abuts against the slider 1 53. Then, the driver 1 51 drives the connecting rail 1 52 to move downward, causing the slider 1 53 to move downward along the inclined slot frame 1 46. The installation slide 31 moves downward and is sleeved on the column 23 and the lower guide rail 44. The slide slot 313 is opposite to the positioning guide rail 10, and then slides between the positioning guide rail 10 and the lower guide rail 44 under the conveyance of the belt 22.

[0038] It should be noted that the reset rack 9 is fixed between the connecting beam 43 and the positioning guide rail 10 through the suspension rod 8 .

[0039] It should be noted that the first driver 51 and the second driver 61 are both selected from any one of an electric push rod, a hydraulic cylinder and a pneumatic cylinder.
