Description

Technical Field

[0001] The utility model relates to the technical field of sealing strip production equipment, in particular to a cutting device for refrigerator sealing strips. Background Art

[0002] The refrigerator sealing strip is a refrigerator accessory used to seal between the refrigerator door and the refrigerator body. It consists of two parts, one is a soft polyvinyl chloride (SPVC) jacket, and the other is a magnetic strip. The sealing strip must go through a cutting process during the production process, that is, the long sealing strip is cut into short strips of specified requirements.

[0003] However, the existing cutting devices mainly rely on manpower for cutting, which has high work intensity and large error in the cut length, thus affecting the subsequent welding work.

[0004] For example, a seal cutting device for refrigerator production disclosed in Chinese patent CN208375353U inserts the seal into the guide slot, starts the drive motor to make the material conveying roller start to rotate and push the seal forward, the driving shaft drives the driven shaft to rotate through the bevel gear, drives the driving gear and the driven gear to rotate, and the driven gear rotates while moving around the driving gear, and uses the second connecting rod to push the cutting knife frame to reciprocate on the supporting beam to cut the seal. When the cutting knife needs maintenance and repair, remove the locking screw, pull the cutting knife out of the T-slot, and perform maintenance or replacement.

[0005] However, in the prior art, when the seal is cut, there is no corresponding limiting structure when the seal is transmitted, which causes the seal to be skewed when it is transmitted to the bottom of the cutting structure for cutting, resulting in uneven cutting ends of the seal.

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.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0028] A refrigerator seal cutting device comprises a support leg 1. A conveying structure is arranged on the top and left side of the support leg 1. A power structure is installed on the top of the support leg 1. A cutting structure is connected to the front of the power structure.

[0029] The transmission structure includes a transmission unit and a supporting connection unit. The transmission unit includes a rotating motor 102, the output end of the rotating motor 102 is connected to a driving shaft 103, the outer surface of the driving shaft 103 is connected to a driving wheel 104, the outer surface of the driving wheel 104 is connected to a driven wheel 107, the driven wheel 107 is connected to a driven shaft 108 inside, and a guide groove 110 is provided on the right side of the driving wheel 104. The supporting connection unit includes a mounting frame 101, a support rod 105 is provided on the front of the mounting frame 101, a fixed rod 106 is fixedly connected to the right end of the support rod 105, and a support rod 2 109 is provided on the lower side of the support rod 105.

[0030] The left side of the mounting frame 101 is detachably connected to the rotating motor 102, a circular hole is opened at the left end of the front side of the support rod 105, and the inside of the circular hole is rotatably connected to the outer surface of the driving shaft 103, and a circular hole 1 is opened at the left end of the front side of the support rod 2 109, and the inside of the circular hole 1 is rotatably connected to the outer surface of the driven shaft 108.

[0031] By setting up the transmission structure, the rotating motor 102 is used to drive the driving shaft 103 and the driving wheel 104 to rotate, thereby driving the driven wheel 107 and the driven shaft 108 to rotate synchronously. The sealing strip can be transmitted by utilizing the grooves provided on the surfaces of the driving wheel 104 and the driven wheel 107. At the same time, the setting of the guide groove 110 can ensure that the sealing strip will not be skewed during the transmission process, and the incision will be more neat when cutting.

[0032] When the sealing strip needs to be transported, the sealing strip is passed through the grooves formed on the outer surfaces of the driving wheel 104 and the driven wheel 107, and then the rotating motor 102 is started to drive the driving shaft 103 and the driving wheel 104 to rotate, thereby driving the driven wheel 107 to rotate synchronously, so as to transport the sealing strip and allow the sealing strip to enter the rectangular through hole formed on the left side of the guide groove 110, so that the sealing strip will not be skewed during the transportation process, and the incision can be more neat when the sealing strip is cut.

[0033] Embodiment 2:

[0034] On the basis of the first embodiment, the power structure includes a workbench 201, a back plate 202 is fixedly connected to the back of the workbench 201, a mounting plate 203 is fixedly installed on the top of the back plate 202, an asynchronous motor 204 is detachably installed on the left side of the mounting plate 203, and a threaded rod 205 is connected to the output end of the asynchronous motor 204. The top surface of the workbench 201 is fixedly connected to the bottom surface of the guide groove 110, the left side of the back plate 202 is fixedly connected to the right end of the mounting frame 101, the left side of the workbench 201 is fixedly connected to the right end of the supporting rod 2 109, and the left side of the front of the back plate 202 is fixedly connected to one end of the back of the fixing rod 106.

[0035] The cutting structure includes a slider 301, a connecting plate 302 is fixedly installed on the front of the slider 301, a slide cylinder 303 is fixedly installed on the bottom of the connecting plate 302, a slide column 304 is slidably connected to the bottom end of the slide cylinder 303, a spring 305 is fixedly connected to the bottom of the slide cylinder 303, a pressing plate 306 is fixedly connected to the bottom end of the slide column 304, a cutter 307 is fixedly installed on the bottom of the pressing plate 306, and a tool holder 308 is arranged at the bottom of the cutter 307. A threaded hole is opened in the middle of the top surface of the slider 301 near the back end, the inside of the threaded hole is threadedly connected to the outer surface of the threaded rod 205, the outer surface of the slider 301 is slidably connected to the inside of the slide groove opened in the middle of the front of the back plate 202, and the tool holder 308 is fixedly installed inside the rectangular groove opened in the middle of the top surface of the workbench 201.

[0036] By setting up the power structure and the cutting structure, the asynchronous motor 204 is used to drive the threaded rod 205 to rotate, thereby driving the slider 301 to reciprocate, so that the slide cylinder 303, the slide column 304, the pressing plate 306 and the cutter 307 can be reciprocated, and the seal can be cut in equidistant segments. The setting of the knife holder 308 can prevent the blade from being damaged when cutting with the cutter 307.

[0037] After the sealing strip is transmitted to the bottom of the cutter 307 via the transmission structure, the asynchronous motor 204 is started to drive the threaded rod 205 to rotate. The threaded connection between the slider 301 and the threaded rod 205 can drive the slide cylinder 303, the slide column 304 and the pressing plate 306 to reciprocate, so that the cutter 307 descends to cut the sealing strip. At the same time, when the cutter 307 abuts against the sealing strip, the slide column 304 slides inside the slide cylinder 303 to compress the spring 305. The stress of the spring 305 can make the cutter 307 cut the sealing strip more thoroughly. The setting of the knife holder 308 can effectively prevent the cutter 307 from colliding during the cutting process to avoid damage to the blade.
