Description

Technical Field

[0001] This utility model relates to the field of envelope folding technology, specifically to an automatic folding device for envelopes that are folded evenly. Background Technology

[0002] An envelope is generally a bag-shaped package used for mailing letters and protecting their contents. Envelopes are typically rectangular paper bags. Standard envelopes usually have a pre-printed writing format; simply write the recipient's postal code, address, and name, as well as the sender's address, name, and postal code, and affix sufficient postage. During the processing, the edges of the envelope are usually folded.

[0003] In the traditional process of folding envelope edges, operators usually need to manually fold each edge of the envelope one by one. This method has problems such as uneven folding and slow speed. To address these issues, we propose an automatic envelope folding device that folds evenly. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] This invention provides an automatic envelope folding device that ensures even folding. A fan blows one end of the envelope on a conveyor belt, and the folding plate and baffle fold the envelope, replacing manual folding. This ensures even folding and increases folding speed. A motor drives a lead screw to slide the baffle up and down, allowing for height adjustment and thus adjusting the folding position of the envelope, enhancing the device's practicality.

[0029] Figures 1-5 The diagram shown is a structural schematic of one embodiment of an automatic folding device for evenly folded envelopes according to this invention. Please refer to [link / reference]. Figures 1-5 The automatic folding device for evenly folded envelopes according to this embodiment includes a support conveying component 100, a blowing component 200, and a folding adjustment component 300 in its main body.

[0030] The supporting conveyor assembly 100 includes two vertically arranged side plates 110, a first conveyor belt 120 disposed on one side inside the two side plates 110, and a second conveyor belt 130 disposed on the other side inside the two side plates 110. A gap is left between the first conveyor belt 120 and the second conveyor belt 130. A limiting plate 111 is provided at the upper end of the side plate 110. Preferably, in this embodiment, a rod 112 is vertically fixed at the lower end of the limiting plate 111. A slot 113 is provided on the side plate 110, and the rod 112 is inserted into the slot 113. The limiting plate 111 is inserted into the side plate 110 under the action of the rod 112 and the slot 113. Later, the operator can manually remove the limiting plate 111 from the side plate 110 to disassemble the side plate 110.

[0031] The blower assembly 200 includes a mounting plate 210 vertically mounted inside two side plates 110 and having through holes, and a blower fan 220 disposed within the through holes of the mounting plate 210. Preferably, in this embodiment, bolts 114 are provided on the outer wall of the side plate 110, the bolts 114 penetrating the side plate 110 to the mounting plate 210. The mounting plate 210 is vertically mounted on the side plate 110 under the action of the bolts 114. Later, the operator can remove the bolts 114 to disassemble the mounting plate 210 so as to disassemble, repair or replace the blower fan 220 on the mounting plate 210. Multiple through holes are equally spaced on the mounting plate 210, and a blower fan 220 is disposed in each through hole. The multiple through holes and the blower fan 220 ensure that the envelope that needs to be folded is blown up.

[0032] The hem adjustment assembly 300 includes a hem plate 310 vertically disposed on the upper end of the side plate 110, a motor 320 disposed in the middle of the upper end of the hem plate 310, a lead screw 330 disposed at the output end of the motor 320, a slider 340 threaded outside the lead screw 330, and a baffle 350 fixed on the outside of the slider 340. The hem plate 310 is provided with a groove, and the outer wall of the slider 340 fits against the inner wall of the groove. Preferably, in this embodiment, the folding plate 310 is provided with scale lines 311 on both sides near the end of the baffle 350. The scale lines 311 on the folding plate 310 are provided to know the height of the baffle 350 during adjustment, thereby knowing the height of the envelope folding edge. Limiting blocks 351 are fixed at both ends of the inner side of the baffle 350. A limiting groove is provided on the folding plate 310. The outer wall of the limiting block 351 fits against the inner wall of the limiting groove. When the baffle 350 slides up and down with the slider 340, the limiting block 351 slides synchronously in the limiting groove. During sliding, the limiting block 351 and the limiting groove generate a certain friction force, thereby ensuring the stability of the baffle 350 during up and down sliding adjustment.

[0033] Combination Figures 1-5 This embodiment of an automatic envelope folding device for even folding is used as follows: The operator places the envelope to be folded on the first conveyor belt 120. The first conveyor belt 120 conveys the envelope. When one end of the envelope is conveyed to the gap between the first conveyor belt 120 and the second conveyor belt 130, the blower 220 in the through hole of the mounting plate 210 blows one end of the envelope up while the first conveyor belt 120 continues to convey the envelope. The blower 220 is turned off, and the first conveyor belt 120 drives the envelope to move upward along the folding plate 310. When the top of the envelope reaches the baffle 350, the first conveyor belt 120 continues to drive the envelope upward. When the envelope is folded, the bottom of the folding plate 310 folds the envelope along the part of the folding plate 310 that moves (i.e., the part perpendicular to the first conveyor belt 120), thus automatically folding the envelope. After the envelope is folded, the second conveyor belt 130 transports the folded envelope away, thus replacing the existing manual folding, ensuring uniform folding, and improving folding speed. In actual use, the motor 320 can drive the lead screw 330 to move the baffle 350 up and down to adjust the height of the baffle 350, thereby adjusting the crease position of the envelope and enhancing the practicality of the equipment.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
