AI Technical Summary
Existing sponge rolls suffer from low trimming precision and insufficient flatness during the trimming process. In particular, when trimming the sponge while it is suspended in the air, the middle of the sponge sheet is prone to arching, affecting the flatness and dimensional accuracy of the trimming.
The system employs a combination of support rollers and trimming units. The support rollers support the sponge sheet for trimming, and the connecting sleeve is rotated by a cylinder to achieve contact or separation of the trimming blades. This ensures that the blades retract during the traction installation of the sponge and only come into contact with the sponge again after winding, thus avoiding the impact of uneven traction on trimming.
It improves the trimming precision and the flatness of the sponge roll, avoids sponge deformation caused by trimming in a suspended state, and improves the flatness and dimensional accuracy of the sponge after trimming.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to sponge processing equipment technical field relates to a kind of sponge coiled material trimming device. BACKGROUND
[0002] Cylindrical sponge is formed into coiled material by continuous sheet winding after rotary cutting, due to the flatness defects of two flat end faces of cylindrical sponge and the error of flatness in winding process, so that the edge part of coiled material is not flat and neat, and it is necessary to form specified width coiled material finished product by trimming, the existing method is to place trimming knife above the spread sheet in sheet spread traction state, the edge part is trimmed by trimming knife when sheet passes, due to the existence of sheet extrusion force, sponge is not in flat traction state at cutting position, which easily causes the middle arch state of sponge sheet between two trimming knives, and further affects the flatness and size accuracy of trimming. SUMMARY
[0003] The utility model aims at the above-mentioned problems existing in prior art, provide a kind of sponge coiled material trimming device, the technical problem to be solved by the utility model is how to improve trimming accuracy.
[0004] The utility model discloses a kind of sponge coiled material trimming device, it is characterized by including cloth guide bracket, the cloth guide bracket includes upper mounting plate and the lower mounting plate below upper mounting plate, the upper mounting plate is fixedly provided with a control shaft, the control shaft is rotatably connected with a support roller, two trimming units located at the two sides of support roller are arranged between the lower mounting plate and support roller, the trimming unit includes the connecting sleeve rotatably connected on the control shaft and the cylinder arranged on the lower mounting plate, the cylinder body is hinged on the lower mounting plate, the push rod of the cylinder is hinged on the connecting sleeve, a knife seat is also fixedly arranged on the connecting sleeve, and trimming blade is installed on the knife seat;The connecting sleeve rotation can make trimming blade contact with the sponge sheet on support roller.
[0005] Further, the lower mounting plate is rotatably connected with two cloth guide rollers located at the two sides of support roller.
[0006] The present scheme trims the sponge pulled through the position of support roller at support roller, which is different from the way of trimming down in the state of suspended sponge in prior art, the sponge at support roller will not be deformed due to the contact between trimming blade and sponge, so that trimming accuracy and flatness of sponge after trimming are improved.In addition, trimming blade realizes contact or separation with sponge by the mode that cylinder pushes connecting sleeve to rotate, which can retract trimming blade when sponge cloth is pulled and installed, and make trimming blade contact with sponge when continuous winding is completed after pulling and installation, so that the influence of unevenly pulling sponge cloth on trimming and the influence of trimming blade on pulling and installation can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a structural schematic diagram of this trimming device.
[0008] Figure 2 It is a structural diagram of the support roller.
[0009] In the figure, 11, upper mounting plate; 12, lower mounting plate; 2, control shaft; 3, support roller; 4, cylinder; 5, connecting sleeve; 6, trimming blade; 7, cloth guide roller. DETAILED DESCRIPTION
[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0011] like Figure 1 and Figure 2 The sponge roll trimming device shown includes a cloth guide bracket, which includes an upper mounting plate 11 and a lower mounting plate 12 located below the upper mounting plate 11. A control shaft 2 is fixedly provided on the upper mounting plate 11, and a support roller 3 is rotatably connected to the control shaft 2. Two trimming units are provided between the lower mounting plate 12 and the support roller 3, respectively located on both sides of the support roller 3. The trimming unit includes a connecting sleeve 5 rotatably connected to the control shaft 2 and a cylinder 4 provided on the lower mounting plate 12, the cylinder body of the cylinder 4 is hinged on the lower mounting plate 12, and the push rod of the cylinder 4 is hinged on the connecting sleeve 5. A knife holder is also fixedly provided on the connecting sleeve 5, and a trimming blade 6 is installed on the knife holder; the rotation of the connecting sleeve 5 can make the trimming blade 6 contact the sponge sheet on the support roller 3; two cloth guide rollers 7 are rotatably connected to the upper mounting plate 12, respectively located on both sides of the support roller 3.
[0012] This solution trims the sponge at the support roller 3 as it is pulled through. Unlike the prior art method of trimming with a knife while the sponge is suspended, the sponge at the support roller 3 is not deformed by the contact between the trimming blade 6 and the sponge, thereby improving trimming accuracy and the smoothness of the sponge after trimming. Furthermore, the trimming blade 6 utilizes the cylinder 4 to rotate the connecting sleeve 5 to achieve contact and separation with the sponge. This method allows the trimming blade 6 to be retracted during the sponge cloth's pulling and installation, and then re-engaged during the continuous rewinding process after the pulling and installation are completed. This prevents the effects of uneven sponge cloth pulling on the trimming process and the effects of the trimming blade 6 on the pulling and installation process.
[0013] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
