Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a material conveying device. Background Art

[0002] The blister machine, also known as the thermoplastic forming machine, is a machine that blister-forms heated and plasticized thermoplastic coils such as PVC, PE, PP, PET, HIPS, etc. into various shapes of high-end packaging boxes, frames and other products. During the blister processing, a conveyor belt is used to transport the materials. The tension of the existing conveyor belt will change after long-term use, making the surface loose, which will cause the position of the material on it to shift, thereby increasing the working error of the blister machine. Later, the staff will need to manually adjust the tightness of the conveyor belt, which reduces the degree of automation of the device and increases the work intensity of the workers. In addition, the staff is required to shut down the equipment during the adjustment process, which further reduces the working efficiency of the device and makes the equipment more limited by the conveying device.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figures 1 to 4 As shown, a material conveying device in the embodiment of the first aspect of the utility model comprises a cross bar 1, a baffle 2 is fixedly installed on the top of the cross bar 1, a blister body 3 is fixedly installed on the top of the baffle 2, support legs 4 are fixedly installed on both left and right ends of the cross bar 1, a transmission device 5 is slidably installed inside the top of the support leg 4, a motor frame 8 is fixedly installed on the inner side of the top of the support leg 4, a motor 9 is fixedly installed inside the motor frame 8, and a screw 10 is fixedly sleeved on the output end of the motor 9;

[0023] The transmission device 5 includes a linkage base plate 501, a slot 502 is provided on the inner side of the linkage base plate 501, and convex strips 503 are integrally formed on the inner and outer sides of one end of the linkage base plate 501. A driving rod 504 is fixedly installed on the top of the linkage base plate 501, and a transmission roller 505 is installed inside the top of the driving rod 504 for transmission. A conveyor belt 6 is installed on the surface of the transmission roller 505, and a pressure sensor 506 is embedded inside the surface of the transmission roller 505. A quick-release linkage device 7 is detachably installed inside the slot 502, one end of the pressure sensor 506 is electrically connected to a controller, and the motor 9 is electrically connected to the pressure sensor 506 through the controller. The linkage base plate 501 is slidably installed inside the top of the supporting leg 4 through the convex strip 503, and the shapes of the two are adapted to each other.

[0024] In the above embodiment, it should be noted that there are several pressure sensors 506. Therefore, when the transmission roller 505 rotates with the conveyor belt 6, the controller can perform a comprehensive comparison based on the signals transmitted by multiple pressure sensors 506 to determine whether it is necessary to control the motor 9 to drive the screw 10 to rotate.

[0025] The technical effect achieved by the above embodiment is: the convex strip 503 can ensure that the sliding of the linkage bottom plate 501 is smoother and prevent residual shaking, thereby improving the stability of the device movement, and the pressure sensor 506 is used to effectively receive the pressure signal of the conveyor belt 6 and its surface.

[0026] Example 2

[0027] like Figure 1 and Figure 4 As shown, a material conveying device includes all the contents of Example 1. In addition, the quick-release linkage device 7 includes a collar 701, and sliding cavities 702 are fixedly installed on the left and right ends of the collar 701. The bottom ends of the sliding cavity 702 are respectively provided with sliding grooves and fixedly installed limit rods 703. A rotating rod 704 is rotatably installed inside the limit rod 703. Studs 705 are integrally formed on the left and right ends of the rotating rod 704. A transmission plate 706 is threadedly installed on the surface of the stud 705. An insert plate 707 is fixedly installed on the top of the transmission plate 706. The collar 701 is threadedly installed on the surface of the screw rod 10. The upper end of the transmission plate 706 is slidably installed in the sliding groove at the bottom of the sliding cavity 702. The thread directions of the two studs 705 are set oppositely, and the size of the insert plate 707 is adapted to the size of the slot 502.

[0028] The technical effect achieved by the above embodiment is: the opposite directions of the two studs 705 are used to make the transmission plate 706 move towards or away from each other, so that the plug plate 707 enters or leaves the interior of the slot 502 at the same time, thereby achieving the purpose of quick disassembly and assembly, and the limit rod 703 is used to limit the rotation of the rotating rod 704 in place, thereby achieving the purpose of limiting.

[0029] Working principle: After the conveyor belt 6 has been used for a period of time, its overall length is stretched, and the pressure at the connection with the transmission roller 505 is reduced. The pressure sensor 506 receives the signal and transmits it to the inside of the controller, through which the motor 9 is driven to rotate the screw 10, so that the ring 701 moves outward. At the same time, the ring 701 drives the linkage bottom plate 501 to move outward as a whole through the plug plate 707 embedded in the slot 502. When the transmission roller 505 moves outward, it fits more closely with the conveyor belt 6. Then the pressure sensor 506 recognizes that the pressure signal has returned to normal, and the motor 9 stops rotating to achieve automatic adjustment. When the conveyor belt 6 needs to be replaced, the rotating rod 704 is directly driven to drive the transmission plate 706 to control the plug plate 707 to disengage from the inside of the slot 502, so that the transmission device 5 can be separated from the motor 9 alone, and finally replaced separately.
