Description

Technical Field

[0001] The utility model belongs to the field of plate bonding auxiliary tools, in particular to a rolling glue coating machine. Background Art

[0002] A Chinese patent with application number 202321952072.7 discloses a glue rolling device for bonding large panels, including a glue dispensing roller, a sponge roller brush, a roller shaft, a glue box, a locking frame, a handle mounting flange, and an elastic retaining ring for the handle and the shaft; a glue outlet is provided in the middle of the bottom of the glue box; the glue dispensing roller is arranged in the glue box through a mounting shaft and a nut, and is located directly above the glue outlet; a connecting seat is provided on each side of the bottom of the glue box, and a vertical groove is provided at the bottom of the connecting seat; the glue dispensing roller and the sponge roller are in direct contact after assembly, and when the sponge roller is rolled, the glue dispensing roller will also be driven to rotate under the action of friction.

[0003] The above solution realizes the glue flowing out of the glue box by rotating the glue dispensing roller, and reduces the glue flowing out by applying downward pressure to make the sponge embed into the groove of the glue dispensing roller. During normal gluing, since the gap between the groove between the glue dispensing roller and the glue box is large, when the glue is a relatively thin type of glue, it is easy to cause the glue to flow out directly from the gap of the groove, resulting in too much glue on the sponge roller brush, affecting the gluing of the plate. Utility Model Content

[0004] The utility model aims to provide a rolling glue coating machine which can prevent glue from flowing out naturally and has better sealing performance.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rolling glue coating machine, including a glue bucket for containing glue, a glue outlet with an opening facing downward at the lower end of the glue bucket, a sponge roller rotatably connected to the glue bucket and used for coating glue is provided below the glue bucket, a glue outlet roller rollingly connected to the sponge roller and rotatably connected to the glue bucket is provided between the glue outlet and the sponge roller, a plurality of mutually connected gear teeth are provided on the outer wall of the glue outlet roller, two sealing plates arranged opposite to each other are provided at the glue outlet, the opposite surfaces between the two sealing plates are both arc surfaces, the tops of the gear teeth are in contact with the arc surfaces and dynamically sealed.

[0006] When using this solution, glue is poured into the glue bucket, and then the operator places the entire glue bucket on the plate that needs to be coated with glue. The glue bucket moves to make the sponge roller roll, and the rolling of the sponge roller drives the glue output roller to roll. The rolling of the glue output roller brings the glue out of the glue bucket and makes the glue flow onto the sponge roller. The sponge roller rolls on the plate to complete the gluing.

[0007] Among them, tooth grooves will be formed between several interconnected gear teeth, and the glue in the glue bucket will flow into the tooth grooves. When the glue output roller rolls, the tooth grooves will bring the glue out and flow onto the sponge roller.

[0008] This solution makes the top of the gear teeth contact the curved surface dynamic seal, so that when the glue roller is not rotating, the glue will not overflow from between the glue roller and the curved surface, and the glue will be brought out by the tooth groove when the glue roller rotates. When the glue is relatively thin, it will not overflow naturally, so as not to affect the gluing of the plate.

[0009] Preferably, the top of the gear tooth is a plane.

[0010] The top of the gear teeth is a plane, so as to better seal the contact with the arc surface. The plane is actually an arc surface with a slight arc, but because the gear teeth are small and there are many of them, the top of the gear teeth can be almost a plane.

[0011] Preferably, sealing blocks are rotatably connected to both axial ends of the glue discharge roller, the sealing blocks are located in the glue hopper and fixed to the glue hopper, the sealing blocks are coaxially arranged with the glue discharge roller and dynamically seal with the axial end surface of the glue discharge roller.

[0012] The sealing block can be provided to reduce the glue overflowing from the axial ends of the glue discharging roller.

[0013] Preferably, the sealing block is provided with a positioning portion, the circumferential outer wall of the positioning portion contacts and seals with the arc surfaces of the two sealing plates, and the sealing block is fixedly connected to the sealing plates.

[0014] The sealing plate can be positioned by the positioning part of the sealing block, and the sealing plate and the glue discharge roller are coaxially arranged to ensure that the position between the arc surface of the sealing plate and the glue discharge roller is relatively accurate, and the top of the gear teeth is in close contact with the arc surface to achieve sealing.

[0015] Preferably, both axial ends of the glue hopper are provided with extension parts extending downward, and the extension parts are provided with long holes penetrating along the axial direction of the glue hopper and extending in the up-down direction, the rotating shaft of the sponge roller passes through the long hole and is rotatably connected with the long hole, and the rotating shaft of the sponge roller has a moving space for moving up and down in the long hole; when the glue hopper is placed on the plate, the glue hopper moves downward so that the sponge roller is in rolling contact with the glue outlet roller, and when the glue hopper is not placed on the plate, the sponge roller moves downward so that the sponge roller is not in contact with the glue outlet roller.

[0016] By setting a long hole extending in the up-down direction, the sponge roller can move up-down relative to the glue bucket, so that the sponge roller and the glue outlet roller can be in contact or not in contact. When the sponge roller and the glue outlet roller are not in contact, the entire glue bucket is lifted, and the sponge roller and the glue outlet roller are not in contact. Even if the operator accidentally touches the sponge roller and the sponge roller rotates, it can only idle and cannot drive the glue outlet roller to rotate, thereby preventing the glue bucket from overflowing when not in use.

[0017] Preferably, the long hole is equipped with a locking pin, and when the locking pin is inserted into the long hole, the rotating shaft of the sponge roller cannot move up and down in the long hole.

[0018] When the glue coating of the final area of ​​the plate is completed, the glue discharge roller is not needed to continue discharging glue. At this time, in order to avoid the contact between the glue discharge roller and the sponge roller, the entire glue bucket can be lifted and the locking pin can be inserted into the long hole. After that, when the sponge roller is in contact with the plate, the glue bucket will not move down, so that the sponge roller and the glue discharge roller are not in contact, so that the sponge glue coating can be applied to the final area of ​​the plate, and the glue discharge roller will not bring out excess glue.

[0019] Preferably, the rotation axis of the glue discharging roller and the rotation axis of the sponge roller are in the same vertical plane.

[0020] The rotation axis of the glue discharge roller and the rotation axis of the sponge roller are in the same vertical plane to ensure that the sponge roller is located directly below the glue discharge roller, so that the glue discharge roller and the sponge roller can better cooperate when rolling in contact.

[0021] Preferably, a handle is provided on the outer wall of the glue bucket.

[0022] The handle can facilitate the operator to move the glue bucket back and forth and apply glue.

[0023] The utility model has the advantages of preventing glue from flowing out naturally and having better sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The utility model is further described below based on the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 4 As shown, this embodiment discloses a rolling glue coating machine, including a hopper 1 for holding glue, and a handle 6 is provided on the outer wall of the hopper 1; a glue outlet (not shown) opening downward is provided at the bottom of the hopper 1, and a glue outlet roller 2 rotatably connected to the hopper 1 is provided in the glue outlet; a sponge roller 5 for coating the plate 100 with glue is provided below the glue outlet roller 2, and the sponge roller 5 is rotatably connected to the hopper 1. The glue outlet roller 2 and the sponge roller 5 are rollingly connected, and the rotation axis of the glue outlet roller 2 and the rotation axis of the sponge roller 5 are both on the same vertical plane. Among them, the rotation connection between the glue outlet roller 2 and the sponge roller 5 and the hopper 1 can adopt any existing method that can realize the rotation connection between the roller and the hopper 1, such as the rotation connection realized by the cooperation of the rotating shaft and the bearing.

[0035] like Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, two sealing plates 4 are arranged opposite to each other at the glue outlet of the hopper 1, and the opposite surfaces between the two sealing plates 4 are arc surfaces 41. A plurality of gear teeth 21 connected to each other are arranged on the circumferential outer wall of the glue outlet roller 2, and tooth grooves are formed between two adjacent gear teeth 21; the top of the gear teeth 21 is a plane, and the top of the gear teeth 21 is in dynamic sealing contact with the arc surface 41. Two sealing blocks 3 are arranged in the hopper 1, and the sealing blocks 3 are located at the axial ends of the glue outlet roller 2 and are rotatably connected to the glue outlet roller 2, and the two are in dynamic sealing cooperation. The sealing blocks 3 are arranged coaxially with the glue outlet roller 2 and are provided with a positioning portion 33 in sealing contact with the arc surface 41. The sealing block 3 is provided with a vertically extending first sealing block fixing hole 31, and the sealing plate 4 is provided with a vertically extending sealing plate fixing hole 42. The fixing between the sealing block 3 and the sealing plate 4 is achieved by passing screws through the first sealing block fixing hole 31 and the sealing plate fixing hole 42. The sealing block 3 is also provided with a second sealing block fixing hole 32 extending along the axial direction of the glue discharging roller 2, and a screw is passed through the second sealing block fixing hole 32 to threadably engage with the hopper 1. The hopper 1 is provided with a hopper fixing hole 12 extending up and down, and a screw is passed through the sealing plate fixing hole 42 to threadably engage with the hopper fixing hole 12.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, the hopper 1 is provided with downwardly extending extensions 13 on both sides of the axial direction of the sponge roller 5, and the extension 13 is provided with a long hole 11 that penetrates the axial direction of the sponge roller 5 and extends in the up-down direction.

When the plate 100 is about to be coated with glue, the operator picks up the entire hopper 1, so that the sponge roller 5 moves downward, and the operator inserts the locking pin 7 into the long hole 11 to limit the upper and lower positions of the sponge roller 5, so that the sponge roller 5 does not contact the glue output roller 2. Then the hopper 1 is put back on the plate 100, and the sponge roller 5 completes the final gluing.
